Abstract
The utility model discloses a kind of elevator machine cylinder hawser groove separation preventing devices, including elevator machine cylinder, bracket, plate, micro limit switch and spring, plate and micro limit switch are set to hoist engine and roll on the bracket of side, spring one end is connect with plate, and the other end is connect with bracket, when the hawser on elevator machine cylinder is disengaged from the groove, hawser is outwardly against pushing plate, micro limit switch is touched while plate compressed spring, the hoist engine power contact of travel switch connection disconnects, and realizes that hoist engine shuts down.The utility model structure is simple, easy to operate, quick, hawser is prevented to be disengaged from the groove in cylinder surface cross winding, improves security performance.
Description
Technical field
The utility model relates to a kind of elevator machine cylinder hawser groove separation preventing devices.
Background technique
Hoist engine is the light and small heavy-duty hoisting equipment with roller winding hawser (wirerope or chain) promotion or traction,
Theory structure is simple, is pure electric vehicle mechanical equipment.In the course of work, with the rotation of roller by cable takeup in cylinder surface,
Wiring amount is big, is easy to happen hawser and is disengaged from the groove and cross winding operation, be easy to cause the calculating error of promotion or hauling distance, even
Reversion occurs and causes safety accident.
Summary of the invention
In order to solve the above-mentioned technical problem, it is simple to provide a kind of structure for the utility model, easy to operate, quick, prevent cable
Rope is disengaged from the groove the elevator machine cylinder hawser groove separation preventing device in cylinder surface cross winding.
The utility model is achieved through the following technical solutions:
A kind of elevator machine cylinder hawser groove separation preventing device, including elevator machine cylinder, bracket, plate, micro limit switch and bullet
Spring, plate and micro limit switch are set to hoist engine and roll on the bracket of side, and spring one end is connect with plate, the other end and bracket
Connection, when the hawser on elevator machine cylinder is disengaged from the groove, for hawser outwardly against pushing plate, plate compressed spring while, touches microstroke
The hoist engine power contact of switch, travel switch connection disconnects, and realizes that hoist engine shuts down.
Further, the plate is zigzag engineering plastic flitch.
Further, the micro limit switch is symmetrically arranged at intervals with two.
Further, there are two the spring settings, two springs are separately connected the both ends of plate.
The utility model increases substantially the utility model has the advantages that the present apparatus can prevent hawser to be disengaged from the groove in cylinder surface cross winding
The operating accuracy and security performance of hoist engine.
Detailed description of the invention
Fig. 1 is a kind of elevator machine cylinder hawser groove separation preventing device schematic diagram of the utility model；
Fig. 2 is Fig. 1 side view.
Wherein, 1- elevator machine cylinder, 2- bracket, 3- plate, 4- micro limit switch, 5- spring.
Specific embodiment
As shown in Figure 1, 2, a kind of 1 hawser groove separation preventing device of elevator machine cylinder, including elevator machine cylinder 1, bracket 2, plate 3,
Micro limit switch 4 and spring 5, plate 3 and micro limit switch 4 are set to hoist engine and roll on the bracket 2 of side, spring 5 one
End is connect with plate 3, and the other end is connect with bracket 2, when the hawser on elevator machine cylinder 1 is disengaged from the groove, hawser outwardly against pushing plate 3,
Micro limit switch 4 is touched while 3 compressed spring 5 of plate, the hoist engine power contact of travel switch connection disconnects, and realizes elevator
Machine shuts down.
In the present embodiment, plate 3 is zigzag engineering plastic flitch, and zigzag engineering plastic flitch facilitates processing, contact surface good,
Convenient for hawser outwardly against pushing plate 3.Micro limit switch 4 is symmetrically arranged at intervals with two, and there are two the settings of spring 5, and two
Spring 5 is separately connected the both ends of plate 3, should be so as to move more stable, raising security performance.
Utility model works principle: when hawser is disengaged from the groove, hawser can be outwardly against, and pushes zigzag engineering plastic flitch
It is displaced outwardly, to touch micro limit switch 4, the hoist engine power contact that micro limit switch 4 connects is disconnected, final to realize
Hoist engine shuts down.Only after hawser retracts elevator 1 card slot of machine cylinder, the zigzag engineering plastic flitch 3 of groove separation preventing device
It is resetted under the traction of two springs 5, micro limit switch 4 is just capable of resetting, and hoist engine could restart.
Technical solution provided by utility model embodiment is described in detail above, it is used herein specifically a
Example is expounded the principle and embodiment of the utility model embodiment, and the explanation of above embodiments is only applicable to help
Understand the principle of the utility model embodiment；At the same time, for those skilled in the art is implemented according to the utility model
Example, there will be changes in terms of specific embodiments and scope of application, in conclusion the content of the present specification should not be construed as
Limitation to utility model.
