[0001] This utility model relates to the technical field of anti-slip cable clamps for coal mining machines, and in particular to a safety anti-slip cable clamp structure for underground coal mining machines. Background Technology

[0002] Cable clamps for coal mining machines are injection molded from nylon 66 with added flame retardants and antistatic agents and a steel frame. Depending on the working face requirements of the coal mining machine, they are connected by pins or bolts to form protective channels for cables or water pipes. The cable clamp structure is crucial when the coal mining machine is operating underground. However, during use, multiple cable clamps are often connected end-to-end, but this connection requires bolts, making the splicing process complex and lengthy. If a cable clamp in the middle section malfunctions, the cable clamps at both ends must be removed, extending the maintenance process and affecting the normal operation of the coal mining machine. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a safety anti-slip cable clamp structure for underground coal mining machines, which solves the technical problem of complex cable clamp assembly and achieves the goal of improving practicality.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a safety anti-slip cable clamp structure for underground coal mining machines, including a cable clamp body as a supporting foundation, wherein the cable clamp body is provided with a docking component for facilitating the connection between each other, and a clamping component for clamping and fixing the cable is provided inside the cable clamp body.

[0005] The docking assembly includes a docking seat fixedly connected to one end of the cable clamp body. The end of the cable clamp body away from the docking seat has a rotating arc-shaped groove. The middle of the rotating arc-shaped groove is a docking slot inside the cable clamp body. Limiting seats are fixedly connected to the top and bottom ends of the cable clamp body away from the docking seat. A support tube is fixedly connected to the middle of the opposite ends of the two limiting seats. Vertical sliding grooves are opened on both sides of the support tube. A limiting rod is slidably connected to the inside of the support tube. An extension sliding rod fixedly connected to the limiting rod is slidably connected to the inside of the vertical sliding groove. A return spring is connected between the limiting rod and the support tube.

[0006] Preferably, the docking seat is fitted with the docking slot, and the limiting rod is fitted with the hole on the docking seat.

[0007] Preferably, the length of the limiting rod extending out of the inner side of the support tube is less than the length of the vertical slide groove, and the portion of the limiting rod near the rotating arc groove is inclined.

[0008] Preferably, the clamping assembly includes a fixed base fixedly connected to both ends of the inner side of the cable clamp body, a horizontal adjustment groove is provided through both sides of the fixed base, a support base is rotatably connected to the inner side of the fixed base, a clamping roller is rotatably connected to the top of the support base, and a clamping limiter is spirally connected to the outer side of the connection between the support base and the fixed base.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] The use of bolts for connecting these cable clamps makes the splicing process complex and lengthy. If a problem occurs in the middle section of multiple cable clamps, the cable clamps at both ends of that section must be removed, thus prolonging the entire maintenance process and affecting the normal operation of the coal mining machine. Please refer to... Figures 1-5 This embodiment provides a safety anti-slip cable clamp structure for underground coal mining machines, solving the technical problem of complex cable clamp assembly. The device includes a cable clamp body 1 as a supporting foundation, with docking components 2 on the cable clamp body 1 for facilitating connection between pairs of clamps, and clamping components 3 on the inner side of the cable clamp body 1 for clamping and fixing the cable. The docking components 2 make the connection process between pairs of cable clamp bodies 1 more convenient and secure, while the clamping components 3 can clamp and fix the cable inside the cable clamp body 1.

[0027] In the traditional use of cable clamps, multiple cable clamps are often connected and fixed in pairs as needed. However, existing cable clamps require bolts for connection, which is cumbersome and inconvenient. To solve this problem, docking component 2 is proposed. The docking assembly 2 includes a docking seat 21 fixedly connected to one end of the cable clamp body 1. A rotating arc groove 22 is provided at the end of the cable clamp body 1 away from the docking seat 21. A docking slot 23 is provided in the middle of the rotating arc groove 22 inside the cable clamp body 1. The docking seat 21 and the docking slot 23 fit together, which makes the calibration during the docking process more convenient. Limiting seats 24 are fixedly connected to the top and bottom ends of the side of the cable clamp body 1 away from the docking seat 21. A support tube 25 is fixedly connected to the middle of the opposite ends of the two limiting seats 24. Vertical sliding grooves 26 are provided on both sides of the support tube 25. A limiting rod 27 is slidably connected to the inside of the support tube 25. The limiting rod 27 fits into the hole on the docking seat 21. An extension sliding rod 28 fixedly connected to the limiting rod 27 is slidably connected to the inside of the vertical sliding groove 26. A return spring 29 is connected between the limiting rod 27 and the support tube 25.

[0028] To ensure that the portion of the limiting rod 27 extending inside the support tube 25 can be completely retracted into the support tube 25, the length of the portion of the limiting rod 27 extending inside the support tube 25 is less than the length of the vertical slide groove 26, and the portion of the limiting rod 27 near the rotating arc groove 22 is sloped, in order to ensure that the limiting rod 27 can retract more quickly when subjected to resistance.

[0029] The two cable clamp bodies 1 are connected by engaging the docking seat 21 into the docking slot 23 on the other cable clamp body 1. During this process, the end of the docking seat 21 will first abut against the inclined part of the limiting rod 27 and retract. Then, the limiting rod 27 will retract completely into the support tube 25 until the hole on the docking seat 21 corresponds to the limiting rod 27. At that time, the return spring 29 inside the support tube 25 will push the limiting rod 27 to reset, thereby engaging it into the hole on the docking seat 21 to achieve the limiting. When disassembling, the extension slide rod 28 needs to be pulled manually to pull the limiting rod 27 out of the hole on the docking seat 21 to release the limiting.

[0030] Example 2

[0031] Based on Example 1, Example 1 solved the technical problem of complex cable clamp assembly, but it still has the problem that the clamping spacing of the clamping components cannot be adjusted according to the cable diameter. Figures 1-5As shown, the specific implementation process is as follows: In order to accommodate cables of different diameters and avoid damaging the cable sheath, the clamping assembly 3 includes fixed seats 31 fixedly connected to both ends of the inner side of the cable clamp body 1. Horizontal adjustment grooves 32 are provided through both sides of the fixed seats 31. A support seat 33 is rotatably connected to the inner side of the fixed seats 31. A clamping roller 34 is rotatably connected to the top of the support seat 33. A clamping limiter 35 is screwed to the outer side of the connection between the support seat 33 and the fixed seat 31. The clamping limiter 35 is a bolt limiter. The two fixed seats 31 are located in the middle of the inner side of the cable clamp body 1, which can ensure the stability of the clamped cable.

[0032] To facilitate the sliding adjustment of the support base 33 on the fixed base 31, the connection between the support base 33 and the fixed base 31 is slidably connected to the inside of the horizontal adjustment groove 32.

[0033] During use, the operator loosens the clamping limiter 35, then adjusts the distance between the two support seats 33 according to the cable diameter, and then flips the support seat 33 inside the fixed seat 31, thereby driving the clamping roller 34 inside the support seat 33 until both clamping rollers 34 are in a vertical state, so as to clamp the cable without damaging the cable sheath.
