Description

Technical Field

[0001] The invention relates to the technical field of mining equipment, and in particular to a cable clamp group pulling device used for a long-distance working surface. Background Art

[0002] The coal mining machine on the fully mechanized mining face of the coal mine will drag a power supply cable to power the coal mining machine. The cable is generally placed in a cable clamp group connected in series, from the end of the working face through the cable trough of the scraper conveyor and finally into the coal mining machine electric control box. The cable clamp group connected in series has a structure similar to that of a bicycle chain. It is formed by hinged connection of multiple rigid modules, one end of which is fixed and the other end is connected to the coal mining machine cable device, and is arranged along the entire working face.

[0003] During the cyclic coal cutting process, the coal mining machine moves back and forth from the head to the tail and from the tail to the head. This requires dragging the traction cable clamp group back and forth along the long-distance working face. Due to the long distance and heavy load of the cable clamp group, it is inevitable that the cable clamp group will be stuck, stuck, and interfered, causing the cable clamp group to accumulate on the ground, affecting the traction movement of the coal mining machine. Generally, in actual work, it is often necessary for the on-site operators of the working face to manually drag the cable clamp group, but manual dragging of the cable clamp group is extremely laborious and there is a certain degree of danger. Moreover, in the thin coal seam and ultra-thin coal seam mining working face, it is difficult to manually drag due to the constraints of conditions such as activity space. As the working face advances, if the dragging is not timely, the coal mining machine cable will be squeezed. In severe cases, the cable clamp group will break and damage the internal cable, resulting in a failure to power supply normally, causing the coal mining work to stop, affecting the production progress.

[0004] Up to now, there are devices that provide power from the outside to pull the cable clamp group. For example, patent document CN201510368157.4 discloses a coal mining machine cable clamp pulling device. However, this device requires sensors to monitor its operation, has high cost and poor stability, and when used underground in coal mines, it requires frequent maintenance and replacement, and the actual use effect is poor, making it difficult to promote on a large scale. Summary of the invention

[0005] In order to solve the problems pointed out in the background technology, the present invention proposes a cable clamp group dragging device for long-distance working faces, which changes the original manual cable dragging method of the fully mechanized working face. When the coal mining machine is advanced, it can cooperate well with the follow-up forward movement, and no manual dragging of the cable clamp group is required, thereby improving production efficiency.

[0006] In order to achieve the above object, the technical solution of the present invention is:

[0007] A cable cleat group hauling device for a long-distance working surface comprises a group of supports placed on the ground, two supporting members are symmetrically arranged in the middle of the upper part of the supports, a roller 1 is rotatably connected between the two supporting members, and a roller 2 and a roller 3 for supporting the cable cleat group are respectively arranged on the front and rear sides of the roller 1;

[0008] The left half of the drum one is fixedly connected with a useful winding drum, and one end of the cable clamping plate group passes through the top of the right half of the drum three and the drum two in sequence, then bypasses the winding drum and passes out from the bottom of the winding drum.

[0009] Furthermore, the winding drum includes a retaining ring located on both sides of the drum body and a plurality of support rods radially extending around the retaining ring. The corresponding two support rods on the retaining ring are connected by a cross bar, and the plurality of cross bars are equally spaced and distributed with equal diameters around the drum.

[0010] Furthermore, the outer end of the support rod is welded to the retaining ring, and the inner end is welded to the fixing plate. The fixing plates are provided in two pieces and are welded to the first roller.

[0011] Furthermore, the roller is located at the top of the support, and the support includes a bracket and reinforcing ribs obliquely arranged on both sides of the bracket. A rotating shaft is arranged through the middle of the roller, and both ends of the rotating shaft are abutted against the bracket and locked with nuts.

[0012] Furthermore, the roller 2 is installed between two brackets 2, and the two brackets 2 are symmetrically distributed at the front of the base;

[0013] A rotating shaft 2 is arranged through the middle of the second roller, and two ends of the rotating shaft 2 are respectively abutted against the top of the second bracket and locked with nuts.

[0014] Further, the drum three is installed between two brackets three, and the two brackets three are symmetrically distributed at the rear of the base;

[0015] A rotating shaft 3 is arranged through the middle of the drum 3, and two ends of the rotating shaft 3 are respectively abutted against the top of the bracket 3 and locked with nuts.

[0016] Furthermore, there are two supports, and a wheel is provided at both ends of each support.

[0017] Furthermore, bearings are arranged between the rotating shaft 1 and the roller 1, between the rotating shaft 2 and the roller 2, and between the rotating shaft 3 and the roller 3.

[0018] Through the above technical solution, the beneficial effects of the present invention are:

[0019] In the present invention, one end of the cable clamp group passes over the top of the drum three and the drum two in sequence and then changes direction for the first time, then starts from the top of the winding drum, winds around the winding drum once, passes through the bottom of the winding drum and changes direction for the second time, and at the same time, the winch wire rope is fixed to the position where the cable clamp group changes direction for the first time through the steel plate, and the winch wire rope at the same speed as the coal mining machine drags the cable clamp group forward, so that the cable clamp group is driven to move towards the coal mining machine by winding around the winding drum once, and rolling is formed between the cable clamp group and the drum three and the drum two, so that the cable clamp group is dragged in the same direction and speed when the coal mining machine is towed.

[0020] The present invention completely changes the original way of manually dragging cables on the fully mechanized working face. When the coal mining machine is advanced, the device can cooperate well with the follow-up forward movement, and there is no need to manually drag the cable clamping plate group, thereby improving production efficiency. The device is easy and quick to install, has strong versatility, is a one-time investment fixed equipment, and has low production and manufacturing costs. In short, the present invention greatly reduces the labor intensity of personnel, has a very high cost performance, creates significant economic benefits for reducing production costs, and is suitable for promotion and application.

Example

[0030] like Figure 1 to Figure 5 As shown, a cable cleat group hauling device for a long-distance working surface comprises a group of supports 1 placed on the ground, two supporting members are symmetrically arranged in the middle of the upper part of the support 1, a roller 1 2 is rotatably connected between the two supporting members, and a roller 2 3 and a roller 3 4 are respectively arranged on the front and rear sides of the roller 1 2 for supporting the cable cleat group;

[0031] The left half of the drum 1 2 is fixedly connected with a useful winding drum 5, and one end of the cable clamp group passes through the top of the right half of the drum 3 4 and the drum 2 3 in sequence, then bypasses the winding drum 5 and passes out from the bottom of the winding drum 5.

[0032] In this embodiment, the winding drum 5 includes a retaining ring 501 located on both sides of the drum body and a plurality of support rods 502 radially extending around the retaining ring 501. The corresponding two support rods 502 on the retaining ring 501 are connected by a cross bar 503, and the plurality of cross bars 503 are equally spaced and distributed with equal diameters around the drum 2.

[0033] Specifically, the outer end of the support rod 502 is welded to the retaining ring 501, and the inner end is welded to the fixing plate 6. The fixing plate 6 is provided with two pieces and is welded to the roller 2.

[0034] The roller 2 is located at the top of the support, and the support includes a bracket 7 and reinforcing ribs 8 obliquely arranged on both sides of the bracket 7. A rotating shaft 9 is arranged through the middle of the roller 2, and both ends of the rotating shaft 9 are abutted against the bracket 7 and locked with nuts.

[0035] The roller 2 3 is installed between two brackets 2 10, and the two brackets 2 10 are symmetrically distributed at the front of the base; a rotating shaft 2 11 is arranged through the middle of the roller 2 3, and the two ends of the rotating shaft 2 11 are respectively abutted against the top of the bracket 2 10 and locked with nuts.
