Summary of the invention
The object of the present invention is to provide one can adapt to all size cable channel cover plate, and the accident such as the damage of cable channel cover plate, the injury of personnel workmen effectively can avoided rising and falling, may occur in removal cable trench cover process; Effective raising personnel production efficiency and effectively ensure the integrity of cable channel cover plate with improve power supply reliability telescoping oilostatic cable trench cover take-off and landing device.
The technical solution realizing the object of the invention is:
A kind of telescoping oilostatic cable trench cover take-off and landing device, it comprises load-bearing underframe, scalable underframe forearm, wheel flutter, hydraulic efficiency gear, arm, scalable arm, hoist cable, main support rod, auxiliary support bar; One end of load-bearing underframe arranges scalable underframe forearm, four angles of load-bearing underframe arrange wheel flutter, load-bearing underframe is fixedly connected with main support rod, arm is arranging scalable arm with the side of scalable underframe forearm on load-bearing underframe, one end that arm is relative with scalable arm is connected by bearing with main support rod, the middle part of scalable arm is connected with the mobile terminal of hydraulic efficiency gear, the fixed end of hydraulic efficiency gear is connected with the raised platform of the bottom of main support rod, and the front end of arm has hung suspension hook from above by hoist cable.
The present invention compared with prior art, its remarkable advantage:
(1) the present invention is without manual operation, the personnel that may occur in staff's moved by hand cable channel cover plate process effectively can be avoided to injure accident by a crashing object, stopped safety in production hidden danger, effectively can improve the work efficiency of personnel;
(2) the present invention can stop the infringement that cable channel cover plate occurs in frequent unlatching, closedown, moving process and the accident of power supply caused thereof, and effectively can ensure the reliability of powering.
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of telescoping oilostatic cable trench cover take-off and landing device of the present invention.
Detailed description of the invention
