Abstract
The invention discloses a sliding protective net of a cab of a hydraulic excavator. The sliding protective net comprises a top protective net and a front protective net. The top protective net is arranged on the top of the cab, the front protective net is arranged at the front of the cab, supports which are used for supporting the front protective net are arranged at the lower end of the front of the cab, roller assemblies are arranged on the top of the front protective net, and the front protective net can freely slide on slide grooves in two sides of the top protective net by the aid of the roller assemblies. The sliding protective net has the advantages that the front protective net can freely slide on the slide grooves in the two sides of the top protective net by the aid of the roller assemblies and accordingly can be selectively opened or closed by drivers according to particular operation working conditions and different front visibility requirements on the cab; danger thread mostly comes from falling objects on the top of the cab when high-altitude demolition, natural disaster relief operation and the like are carried out, the life safety of the drivers is required to be protected by effective top protective structures, and the front protective net can selectively slide to the upper portion of the top protective net at the moment, so that double protection effects can be realized.
Description
Technical field
The present invention relates to the sliding protective screening of a kind of hydraulic crawler excavator driver's cabin, belong to excavator technical field of safety protection.
Background technology
When adopting hydraulic crawler excavator to carry out high-altitude dismantling, natural calamity rescue work, most of security threat derives from the falling object at driver's cabin top, therefore needs better top protection structural defence driver life security.Traditional hydraulic crawler excavator protective screening, be generally fixed by bolts to driver's cabin front portion and top, what be arranged on driver's cabin front portion is called front protective screening, and what be arranged on driver's cabin top is called top protective screening.Under the working condition that some are meticulous, driver needs to identify manipulating object exactly, and the existence of front protective screening can reduce the visibility in driver's cabin front greatly, at this moment before just needing dismounting, protective screening is to ensure the clear identification operation obstacle of driver's energy, but protective screening needs demounting tool before dismounting, in addition protective screening quality is general comparatively large, needs multi agent cooperation to complete dismantlement work.Therefore, traditional driver's cabin protective screening, due to the inconvenience used, reducing the flexibility of driver when switching different work operating mode, affecting operating efficiency.
Summary of the invention
The object of the invention is to, provide that a kind of structure is simple, easy to use and flexible, the safe and reliable sliding protective screening of hydraulic crawler excavator driver's cabin, to overcome prior art deficiency.
Technical scheme of the present invention: the sliding protective screening of a kind of hydraulic crawler excavator driver's cabin, comprise the top protective screening being arranged on driver's cabin top and the front protective screening being arranged on driver's cabin front, lower end, driver's cabin front is provided with the support for supporting front protective screening, front protective screening top is provided with roll wheel assembly, and front protective screening can be free to slide by roll wheel assembly on the chute of protective screening both sides, top.
Described top protective screening comprises two symmetrically arranged chutes, two chutes are welded on square steel pipe, and between two chutes, be provided with the first protective screening adopting spring steel wire drawknot, also be respectively arranged with the first steel plate and the second steel plate at the two ends of two chutes, the first steel plate offers two the first through holes.
Described front protective screening comprises outside framework, is provided with the second protective screening adopting spring steel wire drawknot, outside framework side is provided with handle, outside framework one end is provided with the second through hole in outside framework.
Described roll wheel assembly comprises the junction plate be welded and fixed with front protective screening, set square is connected with junction plate with slotted nut by hex screw, and set square can rotate around hex screw, set square is fixed with two studs, at stud, plastic roller is installed.
Described support is made up of U-shaped junction plate and the L shape gripper shoe be welded on U-shaped junction plate, is provided with third through-hole on the supporting plate.
Owing to adopting technique scheme, the invention has the advantages that: before in the present invention, protective screening can be free to slide by roll wheel assembly on the chute of protective screening both sides, top, therefore, front protective screening can when single, without easily movement when instrument, driver can, according to concrete working condition and the different visibility requirement to driver's cabin front, select to open or close front protective screening.In addition; when carrying out some such as high-altitude dismantling, natural calamity rescue works; major part security threat derives from the falling object at drivers' cab top; need better top protection structural defence driver life security; at this moment; can select front protective screening to be slid onto protective screening top, top, form duplicate protection.Therefore, the present invention has the advantages such as structure is simple, flexible and convenient to use, safety is better, and can select different protection requirements according to job site situation, and the life security of driver is effectively protected.

Detailed description of the invention
In order to make the object of the invention, technical scheme and advantage clearly, below in conjunction with drawings and Examples, the present invention is described in further detail.
Embodiment
As shown in Figure 1, the sliding protective screening of a kind of hydraulic crawler excavator driver's cabin of the present invention, comprise the top protective screening 2 being arranged on driver's cabin 1 top and the front protective screening 4 being arranged on driver's cabin 1 front, the support 5 for supporting front protective screening 4 is provided with in lower end, driver's cabin 1 front, front protective screening 4 top is provided with roll wheel assembly 3, and front protective screening 4 can be free to slide by roll wheel assembly 3 on protective screening 2 both sides, top chute 6.See Fig. 2, described top protective screening 2 comprises two symmetrically arranged chutes 6, two chutes 6 are welded on square steel pipe 10, and between two chutes 6, be provided with the first protective screening 7 adopting spring steel wire drawknot, also be respectively arranged with the first steel plate 8 and the second steel plate 9 at the two ends of two chutes 6, the first steel plate 8 offers two the first through holes 11.See Fig. 3, described front protective screening 4 comprises outside framework 12, is provided with the second protective screening 15 adopting spring steel wire drawknot, outside framework 12 side is provided with handle 13, outside framework 12 one end is provided with the second through hole 14 in outside framework 12.See Fig. 4, described roll wheel assembly 3 comprises the junction plate 16 be welded and fixed with front protective screening 4, set square 17 is connected with junction plate 16 with slotted nut 23 by hex screw 19, and set square 17 can rotate around hex screw 19, set square 17 is fixed with two studs 21, at stud 21, plastic roller 20 is installed.The upper and lower, left and right four direction of plastic roller 20 is all limited by the chute 6 of protective screening 2 both sides, top, its main actions is slide anteroposterior, because the junction plate 16 in roll wheel assembly 3 and set square 17 can relatively rotate, junction plate 16 is rigidly connected with front protective screening 4 again and welds together, before institute, protective screening 4 also can rotate by counter roller assembly 3, when protective screening 4 moves before promoting, by adjusting the relative angle of front protective screening 4 and top protective screening 2, guarantee that both do not interfere.See Fig. 5, described support 5 is made up of U-shaped junction plate 24 and the L shape gripper shoe 25 be welded on U-shaped junction plate 24, and gripper shoe 25 is provided with third through-hole 26.
