The utility model content
Technical problem to be solved in the utility model is to provide a kind of device that prevents that the lifting transportation device from falling, this device can in time stop the operation of jacking equipment when lifting transportation device et out of order, the safety misadventure such as prevent to fall, what guarantee to produce carries out smoothly.
The technical scheme that solves the problems of the technologies described above is:
a kind of device that prevents that the lifting transportation device from falling, its formation comprises control handle, the master control pump, the subcontrol pump, terminal pad, control tooth bar, control panel, control handle is connected with an end of the piston push rod of master control pump, the other end of the piston push rod of master control pump is connected by the end of connection pipe with the piston push rod of subcontrol pump, the other end of the piston push rod of subcontrol pump is by terminal pad and control tooth bar, control panel is connected, the master control pump is arranged on upper position in cage or elevator inboard, the subcontrol pump is arranged on cage or elevator inside front top, control tooth bar, control panel is arranged on outside cage or elevator side, the front end of controlling tooth bar is relative with cage or elevator orbit.
The above-mentioned device that prevents that the lifting transportation device from falling, it also has servo-unit, servo-unit is the pressure air receiver, servo-unit is arranged on outside the master control pump, the air extractor duct of the pressure air receiver of servo-unit is connected with the chamber of the piston movement of master control pump, air extractor duct is positioned at piston with respect to a side of control handle, and the controlled valve of air extractor duct is connected with control handle.
The beneficial effects of the utility model are:
The utility model is arranged in cage or elevator, and the orbit that pulls control handle can make the piston push rod of master control pump, subcontrol pump promote control tooth bar and cage or elevator rubs, and stops the operation of cage or elevator, prevents falling accident.The utility model is easy for installation, debugging is simple, result of use is reliable, passenger can be controlled the stop of cage or elevator internally, and the generation of safety misadventure has been avoided in the safety that has greatly improved cage or elevator, guarantee the safety in production of enterprise, improved the economic benefit of enterprise.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure, mark is as follows: control handle 1, servo-unit 2, master control pump 3, subcontrol pump 4, control tooth bar 5, control panel 6, connection pipe 7, terminal pad 8, connecting rod 9, piston 10, cage or elevator 11, track 12.
The specific embodiment
The utility model is comprised of control handle 1, servo-unit 2, master control pump 3, subcontrol pump 4, terminal pad 8, control tooth bar 5, control panel 6.
Show in figure, the utility model is arranged in cage or elevator 11, master control pump 3 is arranged on upper position in cage or elevator 11 inboards, subcontrol pump 4 is arranged on cage or elevator 11 inside front tops, control tooth bar 5, control panel 6 are arranged on outside cage or elevator 11 sides, and the front end of controlling tooth bar 5 is relative with cage or elevator 11 orbits 12.
Show in figure, control handle 1 is long handle, and its middle part has rotating shaft to fix, and the upper end of control handle 1 is connected with an end of the piston push rod of master control pump 3, and the lower end of control handle 1 is the push-and-pull part, and operating personal can carry out push-and-pull.
Show in figure, the other end of the piston push rod of master control pump 3 is connected by the end of connection pipe 7 with the piston push rod of subcontrol pump 4, and the other end of the piston push rod of subcontrol pump 4 is connected with control tooth bar 5, control panel 6 by terminal pad 8.
