Abstract
A falling resistant safety device of a building construction lifter is characterized in that a protection gear is installed on a falling resistant plate of the falling resistant safety device. The protection gear comprises a protection gear body meshed with a rack and back wheels close to the back of the rack. When the falling resistant safety device works, the back of the rack is provided with two back wheels, and the protection gear body meshed with the rack is stressed by deformation force firstly, thereby enabling a gear of the falling resistant safety device not to be stressed, and obtaining effects that the falling resistant safety device is stressed slightly and is protected.
Description
Technical field
The utility model relates to a kind of building construction hoist anti-dropping safety device, belongs to the construction machinery equipment field.
Background technology
Building construction hoist gear cone cydariform gradual anti-falling safety device; belong to gradual anti-falling safety device by speed control; be that the building hoist that standard knot is equipped with tooth bar prevents the safety device that cage falls; before the utility model is made; rack-and-pinion building hoist gear cone cydariform gradual anti-falling safety device; the unprotect device; adjust improper or adjust when untimely in the track adjusting wheel of building hoist cage; cage is in operation to produce and waves; thereby anti-dropping safety device is caused lateral impact forces; when the cage loaded weight departs from center of gravity on the other hand; also can cause the stressed increase of anti-dropping safety device; the power of above-mentioned generation all acts on the gear cone cydariform anti-dropping safety device; can cause the anti-falling safety device early failure, need often to change anti-dropping safety device, if anti-dropping safety device can not normally use; can have influence on the safety of building hoist, generation causes the accident.
The utility model content
At the deficiency of prior art, the utility model provides a kind of building construction hoist anti-dropping safety device.
A kind of building construction hoist anti-dropping safety device is characterized in that: on the anti-fall plate of anti-dropping safety device, the protection gear is installed, the protection gear comprises and tooth bar ingear protection gear and the close backgear in the tooth bar back side.
On the anti-fall plate of anti-dropping safety device, at least two protection gears are installed, respectively on the both sides up and down of anti-dropping safety device gear.
The back lash of protection wheel and rack is less than the back lash of anti-dropping safety device wheel and rack.
The technical scheme of a kind of building construction hoist anti-dropping safety device of the utility model is: on anti-fall plate, increase one or two protection gear is installed, absorb stressed under the various situations, anti-dropping safety device is in be not subjected to the state of unusual power, guarantee the normal use of anti-dropping safety device.
Structure of the present utility model is:
The engagement of protection wheel and rack; there are two backgears at the back side of tooth bar; since the back lash of protection gear assembly and tooth bar less than; the back lash of anti-dropping safety device wheel and rack; backgear and protection gear digest improper stressed; the anti-dropping safety device gear does not stress, and plays the effect of protection anti-dropping safety device.
During the utility model work, there are two backgears at the back side of tooth bar, with tooth bar ingear protection gear, at first bears deformation force, the anti-dropping safety device gear is not stressed, thereby it is little stressed to reach anti-dropping safety device, plays the effect of protection anti-dropping safety device.
The utility model has the advantages that:
1, protective device is convenient to the position adjustment of anti-dropping safety device output gear and tooth bar, make anti-dropping safety device output gear and tooth bar area of contact, be easier to reach requirement, alleviate the irregular wear of the gear diameter of axle and marginal lubricating bearings, avoid the mal sound and the wearing and tearing of the axially loaded of anti-dropping safety device, guarantee the normal use of anti-dropping safety device.
2; when the track adjusting wheel of building construction hoist cage is adjusted improper or is not in time adjusted; cage is in operation to produce and waves; thereby anti-dropping safety device is caused lateral impact; protective device can guarantee the gap of anti-dropping safety device and tooth bar; make gear and tooth bar normal engaged; alleviate or avoid consequent distortion and instant impact; guarantee that anti-dropping safety device is in normal guard mode; in addition; when the cage loaded weight departs from center of gravity; can cause the stressed increase of anti-dropping safety device, the anti-dropping safety device fender guard absorbs improper power, guarantees that anti-dropping safety device is in normal guard mode.
3, when anti-dropping safety device needs anti-dropping safety device to shield, two backgears and protection gear are braked under the effect of the power that is hit anti-dropping safety device, avoid distortion, thereby make the protection brake action of anti-dropping safety device more reliable.
Description of drawings
The use and the structural representation of Fig. 1, a kind of building construction hoist anti-dropping safety device of the utility model.
The specific embodiment
A kind of building construction hoist anti-dropping safety device of the utility model, the specific embodiment is:
Diagram, anti-fall plate 1 is installed in the cage, with the cage up-and-down movement;
Backgear 2 is installed on the anti-fall plate, contacts with the tooth bar back side;
Anti-dropping safety device gear 5 is with tooth bar engagement anti-dropping safety device transmitting movement;
A kind of building construction hoist anti-dropping safety device, it is characterized in that on the anti-fall plate 1 of anti-dropping safety device 6, at least two protection gears are installed, on the both sides up and down of anti-dropping safety device gear 5, the protection gear comprises the backgear 2 that protects gear 4 and be close to tooth bar 3 back sides with the tooth bar ingear respectively.
The back lash of protection wheel and rack is less than the back lash of anti-dropping safety device protection wheel and rack.
Claims (3)
