Description

Technical Field

[0001] This utility model relates to the field of cable protection technology, and in particular to a cable protection device for coal mining equipment. Background Technology

[0002] Coal mining machines are commonly used equipment in underground operations. However, due to the harsh underground working environment, the cables of coal mining machines are prone to core breakage during use because they lack protective measures. This affects the normal operation of the coal mining machine and seriously restricts coal mine production. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a cable protection device for coal mining equipment, which solves the problem that the cables of coal mining machines lack protection and are easily damaged during underground operations.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A cable protection device for coal mining equipment includes a limiting protection frame and a telescopic protection tube. Shock absorbers are respectively installed at the four corners of the inner wall of the limiting protection frame. Rubber rollers are rotatably installed on the telescopic ends of the shock absorbers. The cable is located between the four rubber rollers. There are two limiting protection frames, and the opposite sides of the two limiting protection frames are connected by the telescopic protection tube.

[0006] Furthermore, the top of the limiting protection frame is provided with a handle.

[0007] Furthermore, a positioning cone is provided at the bottom of the limiting protection frame.

[0008] Furthermore, a positioning bolt is provided at the top center of the limiting protection frame. The threaded end of the positioning bolt passes through the top of the limiting protection frame and is connected to a rubber column. The free end of the rubber column abuts against the outer wall of the cable.

[0009] Furthermore, connecting telescopic tubes are connected to opposite sides of the two limit protection frames, and docking frames are installed at the ends of the two connecting telescopic tubes, with magnets installed on the two docking frames.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: During use, when this utility model is fitted onto the cable, the cable will spread the rubber rollers, the rubber rollers will squeeze the shock absorber, and the shock absorber will perform a reset movement, so that the rubber rollers are tightly attached to the outer wall of the cable for clamping. Then, the two limit protection frames are dragged to stretch the telescopic protection tube, increasing the length of protection. This utility model can effectively protect the cable of the coal mining machine, and the retractable design not only occupies little space but is also easy to carry. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0016] A cable protection device for coal mining equipment includes a limiting protection frame 1 and a telescopic protection tube 2. Shock absorbers 3 are respectively installed at the four corners of the inner wall of the limiting protection frame 1. Rubber rollers 4 are rotatably mounted on the telescopic ends of the shock absorbers 3. The cable 12 is located between the four rubber rollers 4. There are two limiting protection frames 1, and their opposite sides are connected by the telescopic protection tube 2. In use, the device is fitted onto the cable 12. The cable 12 then expands the rubber rollers 4, causing the rubber rollers 4 to press against the shock absorbers 3. The shock absorbers 3 then return to their original position, tightly clamping the rubber rollers 4 against the outer wall of the cable 12. Then, dragging the two limiting protection frames 1 stretches the telescopic protection tube 2, increasing the protection length. This device effectively protects the cable 12 of the coal mining machine, and its retractable design not only saves space but also makes it easy to carry.

[0017] The top of the limiting protection frame 1 is provided with a handle 8.

[0018] The bottom of the limiting protection frame 1 is provided with a positioning cone 7. When used on site, the positioning cone 7 is inserted into the ground for fixation, thereby improving the stability of this design.

[0019] A positioning bolt 5 is provided at the top center of the limiting protection frame 1. The threaded end of the positioning bolt 5 passes through the top of the limiting protection frame 1 and is connected to a rubber column 6. The free end of the rubber column 6 abuts against the outer wall of the cable 12. When the telescopic protection tube 2 is stretched to a suitable length, the positioning bolt 5 is turned to fix the cable 12 through the rubber column 6.

[0020] Two limit protection frames 1 are connected to connecting telescopic tubes 9 on opposite sides. The ends of the two connecting telescopic tubes 9 are respectively equipped with docking frames 10, and magnet blocks 11 are respectively installed on the two docking frames 10. When the telescopic protection tube 2 is stretched to the limit position and cannot completely protect the cable 12, this design is added. The two designs are docked through the docking frames 10 on the connecting telescopic tube 9, and then the magnet blocks 11 are attracted to each other to connect, thereby effectively protecting the cable 12.

[0021] When using:

[0022] During use, the operator moves the limit protection frame 1 using the handle 8 installed on it and places it onto the cable 12. During placement, the cable 12 expands the rubber roller 4, which in turn squeezes the shock absorber 3. The shock absorber 3 then returns to its original position, causing the rubber roller 4 to clamp tightly against the outer wall of the cable 12. After placement, the operator presses down on the limit protection frame 1 using the handle 8, causing the positioning cone 7 installed on the lower wall of the limit protection frame 1 to penetrate into the ground for fixation. Once fixed, the operator pulls another limit protection frame 1 using the handle 8, allowing it to slide on the cable 12. This stretches the telescopic protection tube 2, increasing its protective length. After reaching its maximum length, the operator stops and presses down on the handle 8 to move the other limit protection frame... 1. The positioning cone 7 is inserted into the ground for fixation. Then, the positioning bolt 5 is tightened to fix the cable 12 through the rubber column 6, thus limiting the protection of the cable 12 segment. If the protection length needs to be increased, the above steps are repeated to install the next unit. The two units are connected by the docking frame 10 on the connecting telescopic tube 9. The magnet blocks 11 are attracted to each other to connect, which facilitates the protection of the cable 12 for its service length. For details of the telescopic protection tube 2 and the connecting telescopic tube 9, please refer to the telescopic air duct. After use, the operator pulls out the corresponding limiting protection frame 1 from the ground, loosens the positioning bolt 5, so that the two limiting protection frames 1 move relative to each other, the telescopic protection tube 2 retracts, and then the cable 12 is pulled out.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
