Abstract
The invention relates to a portal crane crab, especially to a portal crane walking dolly which can automatically guarantee the gap of a contact surface between the wheel of the walking dolly and a guide rail. The portal crane walking dolly comprises a hoisting mechanism, a dolly travelling mechanism and a dolly frame. The portal crane walking dolly is characterized in that the hoisting mechanism is horizontally mounted at the front row of the dolly frame, the dolly travelling mechanism is composed of the wheel, a gear motor, a shaft coupling, spring dampers and a hinge, the wheel is mounted on the gear motor through the shaft coupling, the hinge is installed on a gear motor base at a position close to the shaft coupling, the two spring dampers are mounted at the end of the gear motor base far away from the shaft coupling and are adjusted to be in a pre-tension state, and the gear motor is hinged to the rear row of the dolly frame through the hinge and the two spring dampers. The portal crane walking dolly provided by the invention has an ingenious structure, automatically adjusts the gap between the wheel and the guide trail by using elastic force of the spring dampers and floating of the hinge and absorbs impact during running so as to reduce the incidence rate of rail gnawing.
Description
Technical field
The invention belongs to a kind of transfer crane crane carriage, relate in particular to a kind of transfer crane crane carriage that can guarantee voluntarily contact surface gap between walking dolly wheel and guide rail.
Background technology
Between existing each transmission device of transfer crane crane carriage, take to be fixedly connected with, when inaccuracy is installed, during the trolley frame distortion, between wheel and track gapped while causing the unstable or operation of operation mechanism impacted, while being reflected on wheel and track, will gnaw phenomenon.
Summary of the invention
A kind of transfer crane that can guarantee voluntarily contact surface gap between walking dolly wheel and guide rail that the object of the invention is to overcome deficiency of the prior art and provide.
The present invention is achieved in that a kind of transfer crane crane carriage, by lifting mechanism, wheeling mechanism and trolley frame form, it is characterized in that: the lifting mechanism level is arranged on the front row of trolley frame, described wheeling mechanism is by wheel, reducing motor, coupler, the spring damping bumper, hinge forms, wheel is installed on reducing motor by coupler, the reducing motor base is equipped with a hinge near on the direction of coupler, an end away from coupler on the reducing motor base is equipped with two spring damping bumpers, the spring damping bumper is adjusted to the pretension state, reducing motor is arranged after being linked to trolley frame by a hinge and two spring damping bumpers.
Described wheeling mechanism is split type layout, take the trolley frame symmetric line as standard, and left and right respectively arranges that one arranges after being placed in trolley frame.
A described hinge and two spring damping bumpers are equilateral triangle to be arranged, hinge arrangement is at vertex position, and two spring damping bumpers are arranged on position, two base angles.
Described wheel surface plating one deck industrial rubber.
The present invention compares with former technology, and apparatus structure is ingenious, utilizes elastic force and the unsteady autonomous adjusting trundle of hinge and the gap between track of spring damping bumper, and launching an attack in Absorption and running, reduce the incidence of gnawing simultaneously.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is along A-A to view in Fig. 1.
Specific embodiments
Embodiment 1: as Fig. 1, shown in 2, a kind of transfer crane crane carriage, by lifting mechanism 1, wheeling mechanism and trolley frame 2 form, it is characterized in that: lifting mechanism 1 level is arranged on the front row of trolley frame 2, described wheeling mechanism is by wheel 3, reducing motor 4, coupler 5, spring damping bumper 7, hinge 6 forms, wheel 3 is installed on reducing motor 4 by coupler 5, reducing motor 4 bases are equipped with a hinge 6 near on the direction of coupler 5, an end away from coupler 5 on reducing motor 4 bases is equipped with two spring damping bumpers 7, spring damping bumper 7 is adjusted to the pretension state, reducing motor 4 is linked to the rear row of trolley frame 2 by a hinge 6 and two spring damping bumpers 7, wheeling mechanism is split type layout, trolley frame 2 symmetric line of take are standard, left and right respectively arranges that one is placed in the rear row of trolley frame 2, a hinge 6 and two spring damping bumpers 7 are equilateral triangle and arrange, hinge 6 is arranged in vertex position, two spring damping bumpers 7 are arranged on position, two base angles, when inaccuracy is installed, during trolley frame 2 distortion, the gapped operation shakiness that causes between wheel 3 operating units, under the effect of hinge 6 and spring damping bumper 7 elastic force, gap smaller, gappedly between wheel 3 operating units automatically become suitable contact condition again, the transfer crane crane carriage reruns steadily.
Embodiment 2: as Fig. 1, shown in 2, a kind of transfer crane crane carriage, by lifting mechanism 1, wheeling mechanism and trolley frame 2 form, it is characterized in that: lifting mechanism 1 level is arranged on the front row of trolley frame 2, described wheeling mechanism is by wheel 3, reducing motor 4, coupler 5, spring damping bumper 7, hinge 6 forms, wheel 3 is installed on reducing motor 4 by coupler 5, reducing motor 4 bases are equipped with a hinge 6 near on the direction of coupler 5, an end away from coupler 5 on reducing motor 4 bases is equipped with two spring damping bumpers 7, spring damping bumper 7 is adjusted to the pretension state, reducing motor 4 is linked to the rear row of trolley frame 2 by a hinge 6 and two spring damping bumpers 7, wheeling mechanism is split type layout, trolley frame 2 symmetric line of take are standard, left and right respectively arranges that one is placed in the rear row of trolley frame 2, a hinge 6 and two spring damping bumpers 7 are equilateral triangle and arrange, hinge 6 is arranged in vertex position, two spring damping bumpers 7 are arranged on position, two base angles, wheel 2 plated surface one deck industrial rubbers, when moving, impacted the hoisting crane crane carriage, while being reflected on wheel 2 and track, in the time of will gnawing phenomenon, by hinge 6 and spring damping bumper 7 impact-absorbings, alleviate probability and the degree occurred of gnawing.
The present invention compares with former technology, and apparatus structure is ingenious, utilizes elastic force and the unsteady autonomous adjusting trundle of hinge and the gap between track of spring damping bumper, and launching an attack in Absorption and running, reduce the incidence of gnawing simultaneously.
