Problems solved by technology

[0003] The safety devices of the electric hoist in the prior art include safety devices such as overload limiter, torque limiter, leakage protector, limit position limiter for rising and falling; Observe the quality of the wire rope with the naked eye before using the electric hoist of the single-girder crane. Although this observation method can simply judge the quality of the wire rope, it is time-consuming and labor-intensive, and when the height of the single-girder crane is too high, the staff cannot Clearly observe the surface of the wire rope, and at the same time, this method of regular inspection of the wire rope cannot detect the safety performance of the wire rope in real time, so there are still potential safety hazards

Embodiment approach

[0042] As an embodiment of the present invention, the induction unit 5 includes an annular sleeve 51, a spring 52, an induction block 53 and a pressure sensor 54; the annular sleeve 51 is fixedly connected with the support module 4; the annular sleeve 51 is set on the wire rope 2; the annular sleeve 51 The inner wall of the inner wall is evenly provided with a circular groove 55; the bottom of the circular groove 55 is fixedly connected with the pressure sensor 54; the side of the pressure sensor 54 away from the bottom of the circular groove 55 is fixedly connected with a spring 52; the end of the spring 52 is fixed away from the bottom of the circular groove 55 An induction block 53 is connected; the side of the induction block 53 away from the bottom of the circular groove 55 protrudes and extends out of the circular groove 55 .

[0043] During operation, when the wire rope 2 is moving in the annular sleeve 51, the surface of the wire rope 2 is in contact with the side of th...

Embodiment 1

[0066] Embodiment 1: including a driving device 1, an alarm device and a steel wire rope 2; the steel wire rope 2 is wound and fixedly connected in the driving device 1; the alarm device is used to alarm the abnormal function of the present invention;

[0067] Also includes:

[0068] The sensing unit 5 is respectively set on the two movable steel wire ropes 2, and the sensing unit 5 can detect the unevenness of the surface of the steel wire rope 2;

[0069] A support module 4, the support module 4 is located below the driving device 1, and the support module 4 can make the sensing unit 5 move;

[0070] The controller is used to control the automatic operation of the electric hoist for the single-girder crane of the present invention.

[0071] The staff turns on the driving device 1 through the controller, the driver in the driving device 1 drives the two steel wire ropes 2 to rotate, the steel wire ropes 2 pass through the induction unit 5, and under the pull of the hook and ...

Embodiment 2

[0082] Embodiment 2: In this embodiment, the annular sleeve 51 is covered with an annular ring 7; the annular ring 7 is connected to the sliding rod 42; the annular ring 7 wraps and fixes the sensing unit 5.

[0083] When working, the steel wire rope 2 moves in the annular sleeve 51. When the deformed part of the steel wire rope 2 passes through the annular sleeve 51, the pressure sensor 54 in the annular sleeve 51 transmits the data corresponding to the deformed steel wire rope 2 to the controller, and the controller Control the alarm device to open and control the driving device 1 to stop working. At this time, under the action of inertial force inside the driver, the steel rope will still move a small distance. At this time, the annular sleeve 51 is to overcome the friction between the deformed steel wire rope 2 and the induction block 53. The annular sleeve 51 and the annular ring 7 are separated from the steel wire rope 2 to move. When the inertial force of the driving dev...

Abstract

The invention relates to the technical field of cranes, in particular to an electric hoist of a single-beam crane. Comprising driving devices, alarm devices and steel wire ropes, the steel wire rope is wound and fixedly connected in the driving device; the alarm device is used for giving an alarm for functional abnormity of the system; the device further comprises sensing units, the sensing units are arranged on the two movable steel wire ropes in a sleeving mode respectively, and the sensing units can detect the concave-convex degree of the surfaces of the steel wire ropes; the supporting module is located below the driving module, and the supporting module can enable the sensing unit to move; the controller is used for controlling the automatic operation of the electric hoist for the single-beam crane; the driving device drives the steel wire rope to move to be matched with the supporting unit to enable the sensing unit to slide, so that the sensing unit can move according to horizontal displacement of the steel wire rope, the situation that workers cannot judge the safety performance of the steel wire rope in real time is avoided, and production practice can be better facilitated.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to an electric hoist for single beam cranes. Background technique [0002] At present, the electric hoist is a kind of lifting equipment, which has the characteristics of small size, light weight, simple operation, and convenient use. Among them, the electric hoist for single-girder cranes is mainly used in machinery manufacturing workshops, and single-girder cranes are more convenient to use in the workshop. The ground will not hinder the workshop manufacturing work. [0003] The safety devices of the electric hoist in the prior art include safety devices such as overload limiter, torque limiter, leakage protector, limit position limiter for rising and falling; Observe the quality of the wire rope with the naked eye before using the electric hoist of the single-girder crane. Although this observation method can simply judge the quality of the wire rope, it is time-consuming and lab...
