Abstract
An emergency manual anti-falling device belongs to the field of safety protective equipment for construction hoists, and comprises a forced lifting device arranged on a suspension cage and provided with a lever; and a safety anti-falling device is connected with the front end of the lever and arranged on a tower track. The emergency manual anti-falling device is characterized in that an operating handle is fixedly arranged on a car wall of the suspension cage; and the tail end of the operating handle is connected with the tail end of the lever of the forced lifting device. When an accident happens, in case that other anti-falling measures of the construction hoist fail to work, workers in distress can use the operating handle to forcibly start the forced lifting device at the top of the car of the suspension cage under the desire for life to clamp the safety anti-falling device on the tower track for emergency brake. The utility model has the advantages that the safety of the suspension cage of the construction hoist is improved, and the subjective initiative of staff is fully used.
Description
Technical field
The utility model provides a kind of urgent manually anti-fall device, belongs to the safety protection equipment field of building hoist.
Background technology
The elevator of construction machine in the prior art generally all is equipped with disconnected rope safety dropping prevent mechanism.These safety dropping prevent mechanisms are wedge formula and the eccentric wheel type clamping mechanisms by the control of traction insurance steel cable.Also have the friction force that tightly relies on track simple in structure that wedge is taken up, grip track could be effectively when having only this moment elevator inclination and wedge sensitive.Facts have proved that there is defective in above-mentioned safety dropping prevent mechanism.
Chinese patent 200920025762.1 discloses the disconnected rope of a kind of building hoist, speed limit forced action type safety anti-falling device, pressure bont and safety anti-falling device are set at the cage top, when occurring breaking the rope situation, pressure makes skewback and frid relative motion, skewback is filled the span of a man's arms in track, make cage stop tenesmus, improved the action sensitivity of anti-fall skewback, improved the safety factor of elevator.The deficiency of its existence is, if machinery or electronic circuit are malfunctioning, when other anti-fall measures are inoperative, then lacks artificial initiatively lifesaving action in danger as last emergency treatment.
The utility model content
According to above the deficiencies in the prior art, the technical problems to be solved in the utility model is: provide a kind of and can improve building hoist cage degree of safety, make full use of the urgent manually anti-fall device of personnel's subjective initiative.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of urgent manually anti-fall device, comprise the pressure bont that is arranged on the cage, force bont to be provided with lever, the regulations and parameters front end connects the safety anti-falling device that the pylon track is provided with, it is characterized in that: fixedly install lever on the railway carriage or compartment wall of cage, lever ends connects the lever end of forcing bont.
When accident, after the anti-fall measure of other of building hoist was inoperative, workman in danger used lever to start the pressure bont of cage car top by force under the desire of seeking survival, and safety anti-falling device is fastened on the pylon track emergency braking.
Wherein preferred version is:
Described lever ends connects the lever end of forcing bont by steel rope or steel wire fuse.Also can be connected through the hinge and force the lever end of bont.Can also adopt gear transmission, perhaps leverage transmission.
Described steel rope or steel wire fuse are walked around the pulley that is arranged on the cage and are connected the lever end of forcing bont.Skidding is set, and the degree of tension of restriction steel rope makes it power transmission promptly and accurately.
The beneficial effect that the urgent manually anti-fall device of the utility model is had is: by fixedly install lever on the wall of the railway carriage or compartment of cage, lever ends connects the lever end of forcing bont, make when having an accident, after the anti-fall measure of other of building hoist is inoperative, workman in danger is under the desire of seeking survival, can use lever to start the pressure bont of cage car top by force, safety anti-falling device is fastened on the pylon track emergency braking.The utility model has improved building hoist cage degree of safety, makes full use of personnel's subjective initiative.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Wherein: 1, cage 2, permanent seat 3, parking brake 4, steel rope 5, pulley 6, lever 7, pylon track 8, safety anti-falling device.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1, the pressure bont that is arranged on the cage 1 is provided with lever 6, and regulations and parameters 6 front ends connect the safety anti-falling device 8 that pylon track 7 is provided with, and fixedly install lever on the railway carriage or compartment wall of cage 1, and lever ends connects lever 6 ends of forcing bont.
Lever both can be a parking brake 3, also can be pedal, can also be rotary handle or button.
When accident, after the anti-fall measure of other of building hoist was inoperative, workman in danger used lever to start the pressure bont of cage car top by force under the desire of seeking survival, and safety anti-falling device is fastened on the pylon track emergency braking.
Lever ends connects lever 6 ends of forcing bont by steel rope 4, also can be connected through the hinge and force the lever end of bont, also can adopt the steel wire fuse, can also adopt gear transmission, perhaps leverage transmission.
Forcing bont, safety anti-falling device and building hoist pylon in the utility model is common prior art, its setting and use to industry technical personnel and grasped.
Principle of work and use:
When taking place to break rope bob cage accident, after the anti-fall measure of other of building hoist is inoperative, workman in danger is under the desire of seeking survival, pass through manual action: manually draw and lift, pin is stepped on etc., use lever to start the pressure bont of cage 1 car top by force, safety anti-falling device 8 is fastened on the pylon track 7, realizes emergency braking.
