Description
Technical field
The utility model relates to a kind of safety caging device, in particular to a kind of limit for preventing steel wire rope of windlass from inverting
Device.
Background technique
On construction site, the aggregate of concrete mixing plant is conveyed based on elevator bucket material-uploading style at present.Using promotion
The concrete mixing plant of bucket material-uploading style has equipment volume small and the installation convenient advantage of transition, therefore is limited the use of by place
The favor at family.
Due to elevator bucket feeding be heavy load starting, strip operation, elevator bucket in operation process, wirerope emptying after due to
The effect of inertia, which can usually wrap back on roller, drives elevator bucket to rise, and causes elevator bucket to rush to summit, be easy to cause great wealth
Produce loss and personal injury.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of limiting device for preventing steel wire rope of windlass from inverting, tools
There is the function of preventing steel wire rope of windlass from inverting.
In order to solve the above-mentioned technical problem, the technical solution of the utility model are as follows:
A kind of limiting device for preventing steel wire rope of windlass from inverting, including elevator bucket, track, hoist engine, wirerope, it is described
Wirerope on hoist engine is connected by the elevator bucket on the fixed pulley and track on track, further includes in the wirerope
The spacing protecting mechanism for preventing wirerope from inverting after draining；The spacing protecting mechanism includes spring, to control elevator electromechanics
Travel switch, torque arm bar and the press rope wheel that machine opens or closes；The upper end of the torque arm bar is equipped with press rope wheel, lower end and installation
Hinged seat on bracket is hinged, and the press rope wheel is close to the wirerope on lifting drum；The torque arm bar be equipped with to
Impact stroke switch opening and closing block, and the travel switch be mounted on on the bracket of block the same side；The spring it is upper
End is connect with the bottom of torque arm bar, and lower end is connect with bracket.
Further, the travel switch is rounded contact.
The beneficial effects of the utility model are:
By adopting the above technical scheme, due to being provided with the limit for preventing wirerope from inverting after the wirerope drains
Protection mechanism wirerope reverse-winding and drives torque arm so that hoist engine continues to run after the wirerope of hoist engine drains
Bar is swung towards travel switch position, and spring is in stretch-like at this time, when the block on torque arm bar strikes the contact of travel switch
When, the contact movement of travel switch, the motor for closing hoist engine shuts down, and hoist engine stops working, to realize prevention volume
Raise the function of machine wirerope reversion.
Detailed description of the invention

Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
A kind of limiting device for preventing steel wire rope of windlass from inverting, including elevator bucket 1, track 2, hoist engine 3, wirerope 4,
Wirerope 4 on the hoist engine 3 is connect by the fixed pulley on track 2 with the elevator bucket 1 on track 2, the hoist engine 3 by
Motor, shaft coupling, brake, gear-box and reel composition, are commonly mounted in rack 9；It further include in the wirerope 4
The spacing protecting mechanism for preventing wirerope 4 from inverting after draining；The spacing protecting mechanism includes spring 5, to control hoist engine 3
The motor travel switch 6, torque arm bar 7 and the press rope wheel 8 that open or close；The upper end of the torque arm bar 7 is equipped with press rope wheel 8,
Lower end and the hinged seat 10 being mounted on bracket 9 are hinged, and the press rope wheel 8 is close to the wirerope 4 on 3 reel of hoist engine；It is described
Torque arm bar 7 is equipped with the block 11 that opens and closes to impact stroke switch 6, and the travel switch 6 be mounted on it is same with block 11
On the bracket 9 of side；The upper end of the spring 5 is connect with the bottom of torque arm bar 7, and lower end is connect with bracket 9.
Specifically, the travel switch 6 is rounded contact.
Working principle of the utility model is:
In use, hoist engine 3 continues to run after the wirerope 4 of hoist engine 3 drains, 4 reverse-winding of wirerope and band
Dynamic torque arm bar 7 is swung towards 6 position of travel switch, and spring 5 is in stretch-like at this time, when the block 11 on torque arm bar 7 strikes row
When the contact of Cheng Kaiguan 6, the contact of travel switch 6 is acted, and the motor for closing hoist engine 3 shuts down, and hoist engine 3 stops work
Make, to realize the function of preventing the wirerope 4 of hoist engine 3 from inverting.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
