Background
When the winch works, the steel wire rope is wound to the inner side of the flange of the winding drum and should rise to the upper layer and be reversely connected
And (5) continuing winding. However, for some reason, the winding of the steel wire rope is not normally continued, and the steel wire rope is climbed, that is, when the steel wire rope is wound inside one flange of the winding drum, the steel wire rope is not continuously wound toward the other flange of the winding drum, but is continuously wound on the nearest circle of steel wire rope on the original position until the winding height of the steel wire rope is higher than the flange of the winding drum, and then the steel wire rope is separated from the winding drum. When climbing rope trouble and taking place, wire rope can be followed the reel flange suddenly and deviate from to lead to pressing disconnected wire rope to take place the accident, lead to the heavy object to fall suddenly, and this trouble is hardly surveyed in advance by the operator in the normal operation of machine, and this can bring extremely people's hidden danger to people's body and property, probably even heavy people financial loss and casualties.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model aims at providing a rope-outgoing prevention protection device for a winch, which can timely provide an alarm when the winch goes out of a rope and stop the winch.
The embodiment of the utility model provides an in adopt following scheme to realize: the utility model provides a protection device that restricts is prevented out by hoist engine, including hoist engine and plunger travel limit switch, still including supporting circuit break bottom plate, round steel and travel switch fixed plate, the mounting bracket at the pivot both ends of hoist drum is installed one respectively support circuit break bottom plate, two support all to install one on the circuit break bottom plate lateral surface travel switch fixed plate, two all fix on the travel switch fixed plate plunger travel limit switch, the both ends of round steel respectively with the upper end fixed connection of the plunger travel limit switch who corresponds, plunger travel limit switch with the controller wired connection of hoist engine.
The utility model relates to an in the embodiment, two the hole of sliding has all been seted up on the upper portion of the bottom plate that opens circuit in the support, the travel switch fixed plate is fixed the middle part of the bottom plate that opens circuit in the support is located the below of hole ground that slides, two are passed respectively at the both ends of round steel the support the hole of sliding of bottom plate that opens circuit is connected with the plunger travel limit switch that corresponds.
In one embodiment of the present invention, two rib plates are symmetrically arranged on the lower portion of the outer side surface of the supporting open circuit bottom plate.
The utility model has the advantages that: the utility model provides a rope protection device is prevented out by the hoist engine, plunger stroke limit switch are used for monitoring whether the hoist engine takes place to climb the rope or go out the rope, and when the round steel was touched, drive plunger stroke limit switch and remove trigger signal, the controller of hoist engine received plunger stroke limit switch's signal after, the action of hoist engine was cut off to guarantee the safety of work. It can be seen that, the utility model discloses when the hoist engine takes place to climb the rope trouble, can in time send the action of reporting to the police and cutting off the hoist engine effectively, avoid wire rope to deviate from the reel to play safety protection's effect, this device is with low costs, and the reliability is high, easy operation. The device can greatly improve the safety of the broken steel wire rope in the hoisting process of the winch and ensure that the steel wire rope is wound in the winch drum. Effectively avoiding accidents caused by rope outgoing.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1 to 4, the present invention provides a rope-out prevention protection device for a winch, including a winch 1 and a plunger travel limit switch 5, further including a supporting circuit-breaking bottom plate 3, round steel 2 and a travel switch fixing plate 4, wherein one supporting circuit-breaking bottom plate 3 is respectively installed on an installation frame 12 at both ends of a rotating shaft of a winch drum 11, one travel switch fixing plate 4 is installed on both outer side surfaces of the two supporting circuit-breaking bottom plates 3, the plunger travel limit switch 5 is fixed on both travel switch fixing plates 4, both ends of the round steel 2 are respectively fixedly connected with the upper ends of plungers of the corresponding plunger travel limit switches 5, and the plunger travel limit switch 5 is in wired connection with a controller of the winch 1; the plunger travel limit switch can be preferably used on an SH-JM8T-A slow-speed winch, the plunger travel limit switch 5 can adopt a ZC-Q55 type, and the plunger travel limit switch 5 is electrically connected with a controller of the winch; plunger travel limit switch 5 is all installed to both sides is too much in order to deal with wire rope production unilateral serving in the position of difference, and the opposite side probably can't trigger switch's the condition, thereby after the serving exceedes appointed number of turns, causes the diameter increase to push up round steel 2, and round steel 2 drives plunger travel limit switch 5's plunger and shifts up trigger switch, and then 1 outage of hoist engine stop operation.
Please refer to fig. 1 to 4, in an embodiment of the present invention, two sliding holes 31 have been all opened on the upper portion of the supporting open circuit bottom plate 3, the travel switch fixing plate 4 is fixed at the middle portion of the supporting open circuit bottom plate 3 and located below the sliding holes 31, two ends of the round steel 2 are respectively passed through the sliding holes 31 of the supporting open circuit bottom plate 3 and connected to the corresponding plunger travel limit switch 5, the sliding holes 31 play a role in guiding and limiting the movement of the round steel 2, so that the round steel 2 can only move along a specified path, and the round steel 2 can only be pushed up by the steel wire rope to pull the plunger travel limit switch 5, thereby ensuring that the plunger travel limit switch is accurately triggered.
Referring to fig. 1 to 4, in an embodiment of the present invention, two rib plates 32 are symmetrically disposed on a lower portion of the outer side surface of the supporting open circuit bottom plate 3 to reinforce the structural strength.
