Description

Technical Field

[0001] The utility model relates to the technical field of cable laying, in particular to a suspension cable card used for laying cables. Background Art

[0002] Cable holes are commonly found connecting the upper and lower midsections of underground mines and are used to lay various cables to provide power or signals to work sites. Laying cables through cable holes effectively shortens cable lengths, improves power supply reliability, and reduces cabling workload compared to laying cables through ramps or existing cable ducts.

[0003] In the existing cable hole opening, since cable clamps are mostly used with a one-side suspension rope type or a two-side suspension rope type, whether it is a one-side suspension rope type or a two-side suspension rope type, if the cable clamp is to pass through the cable hole smoothly, the diameter of the cable hole must be greater than the full length and width of the cable clamp. In actual construction applications, the full length of the cable clamp is much greater than the width, so the diameter of the cable hole must be greater than the full length of the cable clamp. When the diameter of the cable hole is large, higher requirements are placed on the drilling equipment, the construction period is longer, and the construction cost is also higher. If the rock stratum at the cable hole construction point is broken, construction will be more difficult, and the verticality and smoothness of the cable hole will be affected.

[0004] In order to solve the problem of the cable hole needing to be larger in size, the wire rope trough is fixedly connected to the side perpendicular to the cable clamp so that the distance between the two sides of the cable clamp can be roughly the same. Therefore, under the same conditions, the diameter of the constructed cable hole can be reduced, and the requirements for construction equipment can be reduced, thereby shortening the construction period, reducing construction costs and improving the quality of the cable hole.

[0005] However, during the cable laying process, the steel wire rope is exposed to the air for a long time, which may cause the surface of the steel wire rope to rust. Once the steel wire rope is rusted, its strength will be significantly reduced, and it will be prone to breakage under external forces. In addition, the rusted steel wire rope is prone to bending and tangling during use, which not only affects work efficiency but also increases maintenance costs. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a suspension cable clamp for laying cables, which solves the problem that the cable holes need to be opened with larger sizes.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A suspension cable clamp for laying cables includes two symmetrically arranged cable clamp bodies. A wire rope frame is fixedly connected to each of the cable clamp bodies on one side facing away from the other. A rotating push block is threadedly connected to each of the wire rope frames on the other side facing away from the cable clamp bodies. The cable clamp body, wire rope frame, and rotating push block are used to reduce the diameter of the cable hole to be constructed. This reduces the requirements for construction equipment, shortens the construction period, reduces construction costs, and improves the quality of the cable hole.

[0009] As a further improvement of the present invention, two threaded grooves are symmetrically formed on both sides of the cable clamp body plane. A protective pad is fixedly connected to the adjacent sides of the cable clamp body. Bolts are symmetrically threaded into the two opposing threaded grooves, and nuts are threaded into the bolts on the sides away from the hexagonal heads. This provides protection for the cables.

[0010] As a further improvement of the present invention, the steel rope frames are each provided with an oil storage tank inside, and a cover plug is movably connected to the top of the oil storage tank of each steel rope frame. The rotating push block is provided with a contact plate on the side close to the steel rope frame, and the rotating push block is fixedly connected to the side close to the contact plate. The contact plate is provided with a rotation groove on the side close to the rotating push block, and the rotating block and the rotation groove are rotatably connected. Thus, the contact plate can be fixed to the steel rope when the rotating push block is rotated.

[0011] As a further improvement of the present invention, two triangular blocks are symmetrically arranged on the inner wall of the wire rope frame on both sides of the front end of the contact plate. The sides of the triangular blocks close to the inside of the wire rope frame are fixedly connected to springs, and the ends of the springs away from the triangular blocks are fixedly connected to the inside of the wire rope frame. This allows the triangular blocks to be squeezed when the wire rope is introduced.

[0012] As a further improvement of the present invention, the triangular blocks are fixedly connected to a connecting rod on one side close to the interior of the wire rope frame, the top of each connecting rod is fixedly connected to a retaining block, and a liquid outlet groove is provided at the top of each retaining block inside the wire rope frame, so that the anti-rust oil in the oil reservoir can be applied to the surface of the wire rope.

[0013] As a further improvement of the present invention, the other end of the liquid outlet trough is opened at the bottom side of the oil storage tank, and two liquid outlets are symmetrically opened above the triangular block inside the wire rope frame. Therefore, the inclined surface design of the liquid outlet facilitates the outflow of the rust-proof oil.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The cable clamp body, wire rope frame, and rotating pusher are arranged perpendicular to the cable clamp body, making the overall length and width of the device essentially the same. This significantly reduces the diameter of the cable hole required under the same conditions. According to the volume calculation formula (V=πR²h), the engineering workload is proportional to the square of the cable hole radius. This significantly reduces the construction workload and significantly saves costs. Furthermore, the reduced cable hole diameter reduces the requirements for drilling equipment, easing operating conditions. This reduced engineering workload significantly shortens the drilling schedule. The reduced cable hole size also minimizes damage and disturbance to the stratum rock, thereby improving the overall safety factor of the mine. The reduced cable hole diameter requires less wellbore and sealing material, directly reducing material costs. Furthermore, while maintaining operating efficiency, the smaller cable hole diameter can require a more compact and robust wellbore structure, thereby improving overall stability.

[0016] 2. Through the oil storage tank, triangular block and resisting block, when the wire rope moves upward through the bottom end of the hole in the middle of the wire rope frame, the triangular block will be squeezed to move into the wire rope frame. Then, when the triangular block drives the resisting block to no longer block the opening of the liquid outlet tank, the anti-rust oil inside the oil storage tank will flow to the surface of the resisting plate and the inner wall of the wire rope frame. Then, through the movement of the wire rope along the resisting plate and the inner wall of the wire rope frame, the anti-rust oil will be applied to the surface of the wire rope. Applying anti-rust oil can form a protective layer on the surface of the wire rope, isolating the metal surface from contact with these corrosive substances, thereby effectively preventing the wire rope from being damaged by rust and corrosion, and extending its service life. Applying anti-rust oil can also reduce friction between the surfaces of the wire rope, thereby reducing wear, thereby further improving the service life and working efficiency of the wire rope.

DETAILED DESCRIPTION

[0025] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0027] As shown in the figure, a suspension cable clamp for laying cables includes a cable clamp body 101 , a protective pad 103 , a wire rope frame 201 , a rotating push block 203 , a contact plate 204 , an oil storage tank 205 and a triangular block 206 .

[0028] During the cable laying process, a cable hole must first be opened to facilitate cable entry. By arranging the wire rope frames 201 on both sides perpendicular to the two cable clamp bodies 101, the maximum distance between the rotating push blocks 203 can be substantially the same as the maximum distance between the cable clamp bodies 101. This minimizes the size of the cable hole under the same conditions. While maintaining work efficiency, minimizing the cable hole diameter makes the well structure more compact and robust, thereby improving overall stability.

[0029] Furthermore, when the cable hole is opened, the cable needs to be fixed to the cable clamp body 101, and a supporting force needs to be formed by sleeved on the wire rope. When the wire rope moves upward along the hole of the wire rope frame 201, the wire rope will resist the triangular block 206 and move toward the inside of the wire rope frame 201. At this time, since the triangular block 206 and the stop block 208 are fixedly connected by the connecting rod 209, the movement of the triangular block 206 will drive the stop block 208 away from the liquid outlet 207. Since the liquid outlet 207 and the oil storage tank 205 are penetrated, during the movement of the wire rope frame 201 along the wire rope, the anti-rust oil pre-set in the oil storage tank 205 flows through the liquid outlet 211 to the inner wall surface of the wire rope frame 201 where the wire rope is drunk. During the movement of the wire rope frame 201 along the wire rope, the anti-rust oil can be applied to the surface of the wire rope. Applying anti-rust oil can form a protective layer on the surface of the wire rope, isolating the metal surface from contact with these corrosive substances, thereby effectively preventing the wire rope from being damaged by rust and corrosion.

[0030] Furthermore, when the wire rope moves to the appropriate position, the rotating pushing block 203 is rotated to make the rotating pushing block 203 move toward the inside of the wire rope frame 201. Since the rotating block 213 fixedly connected to the side of the rotating pushing block 203 is rotatably connected to the rotating groove 212 opened in the resistance plate 204, the rotating movement of the rotating pushing block 203 will drive the resistance plate 204 to move toward the wire rope, thereby achieving the effect of fixing the wire rope. The wire rope serves as a guide and support structure for cable laying. Its fixation can ensure that the cable follows the predetermined path and position during the laying process to avoid offset or dislocation.

[0031] Furthermore, after the steel wire rope is fixed, the protective pad 103 is attached to the surface of the cable, and then the two cable card bodies 101 are fixed by the threaded connection between the bolt 104 and the nut 105. This will not only fix the cable card body 101, but also prevent the cable from being damaged by the protective pad 103. The protective measure can reduce the risk of the cable being damaged by external factors such as friction, extrusion, and impact, and the protective pad 103 can further enhance the stability of the cable to ensure that it will not loosen due to external factors.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
