Abstract

The utility model provides an automatic retractable cable device for a coal mining face. The automatic retracting and unwinding cable device of the coal mining face includes a cable reel, a transmission shaft, a rotary wheel, a rotary wheel shell and a return spring. There is a cable groove on the cable reel, which is used to fix one end of the cable, and the other end of the cable is freely retractable; the transmission shaft connects the cable reel and the rotary wheel as a whole, and rotates at the same time; one end of the return spring is connected to the rotary wheel, and the other end Connected to the casing of the rotary wheel; when the distance between the brackets increases due to the shifting of the working surface, the cable is forced to stretch outwards and drive the cable reel to rotate, and the rotary wheel is driven to rotate through the fixed shaft, and the return spring is stretched; When the distance between the brackets is reduced by moving the frame again, the cable is loosened. Under the tension of the return spring, the rotary wheel rotates in the opposite direction, driving the cable reel to rotate in the opposite direction, and the cable is automatically wrapped around the cable reel to achieve the purpose of automatically retracting and unwinding the cable. .

Description

Automatic retractable cable device in coal mining face

technical field

The utility model relates to the field of power supply equipment for a coal mining face, in particular to an automatic retractable cable device for a coal mining face.

Background technique

A variety of electrical equipment needs to be arranged in the coal mine mining face, especially the working status monitoring equipment of the fully mechanized mining support, which requires cable power supply. Most of the monitoring equipment is erected on the fully mechanized mining support in the later stage, and cables need to be powered and signal transmitted between the monitoring equipment, so a lot of cables need to be suspended between the fully mechanized mining supports in the later stage. However, due to the staggered shifting of fully-mechanized mining supports, the distance between fully-mechanized mining supports is constantly changing, so the cables must be kept long. The long cables are hung on the fully-mechanized mining support. When the frame is moved, the long cable is easy to fall between the fully-mechanized mining supports. When the frame is moved, it will be broken by the base of the fully-mechanized mining support; On the ground, it cannot be stretched freely, and it will be directly broken by the fully mechanized mining support when moving the frame; it may also trip coal mining workers and cause accidents.

Utility model content

In order to solve the above problems, the utility model provides an automatic retractable cable device for coal mining face with simple structure and stable operation.

The technical solution of the utility model to solve the above-mentioned problems is: the automatic retractable cable device of the coal mining face includes a cable reel, a transmission shaft, a rotary wheel, a rotary wheel shell and a spring.

The above-mentioned automatic retractable cable device on the coal mining face has a cable groove on the cable reel for fixing cables;

The above-mentioned automatic retractable cable device for the coal mining face, the transmission shaft thereof connects the cable reel and the rotary wheel as a whole, so that the cable reel and the rotary wheel rotate at the same time;

In the above-mentioned automatic retractable cable device for coal mining face, the upper end of the transmission shaft is provided with a cable groove, and the cable groove cooperates with the cable groove on the cable reel to fix the cables.

In the above-mentioned automatic retractable cable device for the coal mining face, the transmission shaft is a cross structure, which is installed as a whole with the cable reel and the rotary wheel, and will not rotate relative to each other.

In the above-mentioned automatic retractable cable device for the coal mining face, one end of the return spring is fixed on the casing of the rotary wheel, once fixed on the rotary wheel, and when the rotary wheel rotates, the return spring is driven to stretch or shrink.

The beneficial effect of the utility model is that one end of the cable is fixed through the cable groove, and the long cable is wound on the cable reel. Under the action of tension, the cable wound on the cable reel is pulled out from the cable reel, which drives the cable reel to rotate, drives the rotary wheel to rotate through the transmission shaft, and the rotary wheel rotates to stretch the return spring; , when the distance between the fully mechanized mining supports decreases, the pulling force of the moving frame disappears, the return spring shrinks, and the rotary wheel is driven to rotate in the opposite direction, and the cable reel is driven to rotate in the opposite direction through the transmission shaft, and the cable is wound on the cable reel again to realize automatic cable retraction. To ensure that the cable is always in a stretched state, it will not hang and be crushed, or twisted, broken or tripped.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

As Fig. 1, the utility model comprises cable reel (1), power transmission shaft (3), rotary wheel (5), rotary wheel shell (2) and back-moving spring (6). The cable reel is provided with a cable groove (7), and one end of the cable (4) passes through the cable groove (7) and is fixed, and the long cable (4) is wound on the cable reel (1).

As shown in Figure 2, one end of the return spring (6) is fixed on the rotary wheel housing (2), and the other end is fixed on the rotary wheel (5); the cable reel (1) and the rotary wheel (5) pass through the drive shaft (3) ) are connected as one to realize simultaneous rotation.

When the fully-mechanized mining supports are shifted alternately, the distance between the fully-mechanized mining supports increases, the cable (4) stretches, drives the cable reel (1) to rotate, and drives the rotary wheel (5) to rotate through the transmission shaft (3), and the rotary wheel (5) Relatively rotates with the rotary wheel housing (2), and the return spring (6) is stretched; when the adjacent total mechanized mining supports continue to move and the distance between the fully mechanized mining supports decreases, the cable (4) will When the tension disappears, under the elastic force of the return spring (6), the slewing wheel (5) rotates in the opposite direction, drives the cable reel (1) to rotate in the opposite direction through the transmission shaft (3), and winds the cable (4) back to the cable reel , to achieve the purpose of automatic retractable cable.
