Abstract
The utility model provides a counter weight tower wagon type tension device, which aims at solving the problems that: the maintenance is inconvenient, a reasonable falling-proof protective device is in urgent need, and when the start of an adhesive tape machine is unsmooth, a counter weight box swings and can be seized with a slideway. The essential points of the utility model are that the counter weight tower wagon type tension device is additionally provided with a steel rope electric block overhaul device and takes an electric block as power to tract a steel rope to sequentially pass through a fixed pulley arranged on a tower top and a moving pulley arranged on a weight box and hoist the weight box; a vertical counter weight tension falling-proof device is formed by sequentially connecting the tower top, a hanging bracket, a buffer device, the steel rope and the weight box; and a guide device is a pair of rollers which are arranged at the bottom of the weight box and respectively travel on two sides of a vertical guide rail in the center of the tower. The utility model has the advantages of bringing convenience to maintenance, eliminating safe hidden troubles and ensuring that the weight box smoothly travels without swinging.
Description
Technical field
The utility model relates to bulk material handling equipment--a kind of heavy-hammer tower vehicle-type tension device on the belt conveyer.
Background technology
Take-up device in belt conveyer is the visual plant that guarantees the belt conveyer normal operation, select suitable tension pattern, determine suitable tightening force, belt conveyer is moved more reliably, can also reduce the load of each parts, to saving great deal of investment, play crucial effect.
Long distance, big bandwidth, the conveyer that power is bigger adopts heavy-hammer tower vehicle-type tension device more, it has constant tensile force, thereby it is non-slip to produce enough big friction force assurance load-transfer device between load-transfer device and cylinder, and conveyer is normally moved, and length that can the automatic compensation adhesive tape.Present heavy-hammer tower vehicle-type tension device has the following disadvantages: 1) maintenance is inconvenient.In case need repairing; will employ great amount of manpower and various lifting appliance; 2) it lacks rational fall protection equipment; in case the adhesive tape or the tense wire rope of conveyer rupture; weight box will directly be done the movement of falling object; can form the hidden danger of great bodily injury to the personnel of below, its bottom device and weight box itself are caused major injury.3) not steady when the sealing-tape machine startup, weight box has swing and slideway to have stuck phenomenon to take place.
Summary of the invention
For overcoming the deficiency of prior art, the purpose of this utility model is to provide a kind of heavy-hammer tower vehicle-type tension device, and it is applicable to long distance, big bandwidth, large conveying quantity, the belt conveyer that power is bigger.
The purpose of this utility model is achieved in that it has pylon, weight box, tension rope and tension car, and it is characterized in that: it also is provided with
Steel-wire rope type electric block apparatus for examination and repair, this device are to be power to be arranged on ground-surface electric block, haulage cable, successively the fixed pulley by being arranged on the pylon top, be arranged on the movable pulley on the weight box, the weight box of slinging.Its effect is weight box can be risen to the optional position to overhaul, and can regulate the stroke of weight box simultaneously;
Vertical heavy-hammer tension falling proof device, this device are that pylon top, suspension bracket, shock absorber, steel rope and weight box are connected successively, and shock absorber is made up of spring and compression chamber.When adhesive tape or taut wire fracture of rope, weight box by steel rope and shock absorber, plays a protective role to the weight box of free-falling body after the movement of falling object through a segment distance;
Guide piece, this device are mounted in a pair roller of weight box bottom, respectively in the both sides walking of the vertical guide rail of pylon central authorities, to guarantee the weight box smooth running, not swing.
Compared with prior art, the beneficial effects of the utility model are: it provides convenience for maintenance, has eliminated the potential safety hazard because of adhesive tape or the generation of taut wire fracture of rope, guarantees the weight box smooth running, does not swing.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is a scheme drawing of the present utility model.
Fig. 2 is the scheme drawing of the vertical heavy-hammer tension falling proof device among Fig. 1.
Fig. 3 is the scheme drawing of Fig. 2 shock absorber.
Fig. 4 is that A among Fig. 1 is to view.
The specific embodiment
It has pylon 3, weight box 5, tension rope 10 and tension dolly 12, and it also is provided with
Steel-wire rope type electric block apparatus for examination and repair, this device are to be power to be arranged on ground-surface electric block 1, traction maintenance steel rope 2, successively the fixed pulley 8 by being arranged on the pylon top, be arranged on the movable pulley 9 on the weight box, the weight box of slinging.Steel rope 2 multiplying powers ratio is also to reduce pull of steel wire in 6: 1,8: 1 at 4: 1, with the power of 1/n counterweight weight box is risen to the optional position and overhauls, and weight box is provided with inspection platform 6 and blocks bar.This device is safe in utilization, and it is simple in structure, and is convenient and easy.Can regulate simultaneously the stroke of weight box;
Referring to Fig. 2, vertical heavy-hammer tension falling proof device 7, this device are that pylon top, suspension bracket 71, shock absorber 72, steel rope 74 are connected successively with weight box, the 73rd, and rope clamp.Referring to Fig. 3, shock absorber is made up of spring 721 and compression chamber 722.According to impact load, can adopt different compression springs such as column type spring or disk spring to make shock absorber, can satisfy the various working requirement.And the length that can regulate steel rope is voluntarily regulated the work area, the scope of actv. control survival space.The prevention vertical heavy-hammer tension is under situations such as broken belt, and when adhesive tape or taut wire fracture of rope, weight box by steel rope and shock absorber, plays a protective role to the weight box of free-falling body after the movement of falling object through a segment distance.Also can prevent simultaneously the damage of take-up device.
Adhesive tape conveyor particularly opening the tension variation that glancing impact produces, causes that the flexible drive weight box of adhesive tape slides up and down in the middle of operation.In order to guarantee that weight box steadily do not swing, promptly guarantee the tension stability of the full end face of adhesive tape, set up guide piece 4.Referring to Fig. 4, guide piece is mounted in a pair roller 41 of weight box bottom, respectively in the both sides walking of the vertical guide rail 11 of pylon central authorities, to guarantee the weight box smooth running, not swing.
