Description

Technical Field

[0001] This utility model relates to the field of high-voltage cable laying technology, and more specifically, to a model suitable for long-distance suspension of high-voltage cables. Background Technology

[0002] In underground coal mine roadways, we often see cables of various types. To maintain the aesthetic appeal of the cable routing, we frequently use metal cable hooks to suspend them. These metal hooks are relatively hard and need to be installed on roadway anchor bolts. However, due to the unevenness of the roadway walls and errors during anchor bolt installation, the distance between the cable hook holes often doesn't match the actual anchor bolt spacing, causing difficulties in installing the metal cable hooks. Furthermore, many underground roadways are affected by the environment, construction time, and roof structure, making it impossible to install anchor bolts according to requirements (typically a 1.5-meter cable hook spacing), further complicating cable suspension and necessitating improvements.

[0003] In conclusion, how to provide a model suitable for long-distance suspension of high-voltage cables is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation

[0023] 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 scope of protection of the present utility model.

[0024] The core of this utility model is to provide a model suitable for long-distance suspension of high-voltage cables, which will be described below in conjunction with... Figures 1-5 The diagrams in the document introduce and explain the various components that make up the model:

[0025] The model suitable for long-distance high-voltage cable suspension includes an anchor bolt installed in a mine roadway. A first suspension assembly 1 and a second suspension assembly 2 for suspending the cable are suspended from the outer end of the anchor bolt. A limiting mechanism 6 is installed at the outer end of the first suspension assembly 1. Grooves are formed inside both the first and second suspension assemblies 1 and 2, and connecting mechanisms 5 are installed inside these grooves. Adjustment mechanisms 3 are fitted onto the bottom of the inner walls of both the first and second suspension assemblies 1 and 2, and a driving mechanism 4 is installed inside the adjustment mechanism 3. Specifically, the second suspension assembly 2 and the first suspension assembly 1 can be used to switch the suspension of the high-voltage cable. This allows the device to change the position of the first and second suspension assemblies 1 and 2 during use, adapting to different suspension environments. This enables the device to meet the requirements of long-distance underground high-voltage cable laying and suspension work, thus expanding its applicability and improving its practicality.

[0026] The second suspension assembly 2 includes an S-shaped hook 201, the top of which is attached to the outer end of the anchor rod. An arc-shaped positioning block 202 is installed on the top of the inner wall of the S-shaped hook 201. Slots are provided on both the left and right sides of the arc-shaped positioning block 202. U-shaped locking blocks 203 are slidably connected inside the two sets of slots of the arc-shaped positioning block 202. Threaded holes are provided on the lower surface of the U-shaped locking blocks 203. Bolts 204 are threaded into the threaded holes of the U-shaped locking blocks 203. The upper surface of the bolts 204 abuts against the bottom of the anchor rod. Specifically, by pushing the S-shaped hook 201... 01. The top of the S-shaped hook 201 is suspended to the outer end of the anchor rod. Then, the U-shaped locking block 203 is pushed to engage with the two sets of slots in the arc-shaped positioning block 202. The bolt 204 is rotated to make the upper surface of the bolt 204 abut against the bottom of the anchor rod, so that the S-shaped hook 201 is firmly installed on the outer end of the anchor rod. This eliminates the need for workers to drive anchor rods into the well again during the subsequent laying of high-voltage cables, thereby reducing the resources consumed by workers when using this device to suspend high-voltage cables and improving the practicality of the device.

[0027] The first suspension assembly 1 includes a J-shaped hook 101, with a U-shaped connecting block 102 mounted on the top of the J-shaped hook 101. Grooves are formed on the inner walls of both sides of the U-shaped connecting block 102. A fixing block 103 is rotatably connected inside the two sets of grooves of the U-shaped connecting block 102. A groove is formed on the front of the fixing block 103, and a nut 104 is installed inside the groove of the fixing block 103. The internal thread of the nut 104 is connected to the outer end of the anchor rod. Specifically, rotating the J-shaped hook 101 drives the nut 104 to connect to the outer end of the anchor rod, and pushing the J-shaped hook 101 adjusts and moves its position to a position perpendicular to the ground. The high-voltage cable is suspended to the lower end of the J-hook 101 using the adjustment mechanism 3, so that the high-voltage cable is suspended at the same height during the suspension process, which greatly improves the appearance and standardization of the cable hanging on site. Furthermore, the high-voltage cable can be suspended by switching between the second suspension component 2 and the first suspension component 1. This allows the device to change the position of the first suspension component 1 and the second suspension component 2 according to different suspension environments during subsequent use. In this way, the device can meet the requirements of long-distance high-voltage cable laying and hanging work in the mine, thereby expanding the scope of application of the device and improving its practicality.

[0028] The limiting mechanism 6 includes a U-shaped positioning frame 601, which is installed on one side of the U-shaped connecting block 102. A threaded hole is provided on the side of the U-shaped positioning frame 601 away from the U-shaped connecting block 102. A screw 602 is threaded into the internal thread of the threaded hole of the U-shaped positioning frame 601. Threaded holes are also provided on the sides of the U-shaped connecting block 102 and the fixing block 103 near the U-shaped positioning frame 601. The positions of the threaded holes of the U-shaped connecting block 102 and the fixing block 103 are located on the rotation path of the screw 602. Specifically, by rotating the screw 602, the external thread of the screw 602 passes through the internal threaded hole of the U-shaped positioning frame 601 and connects to the threaded holes of the fixing block 103 and the U-shaped connecting block 102. This limits the rotational position of the fixing block 103 within the two sets of grooves of the U-shaped connecting block 102, thereby improving the stability of the J-shaped hook 101 during use.

[0029] The adjusting mechanism 3 includes a fixed sleeve 301. The inner wall of the fixed sleeve 301 is threaded, and a fixed plate 303 is connected to the internal thread of the fixed sleeve 301. The upper surface of the fixed plate 303 has two sets of through holes, and steel strands 302 are installed inside the two sets of through holes of the fixed plate 303. The steel strands 302 are sleeved on the outer ends of the J-type hook 101 and the S-type hook 201. Specifically, when the steel strands 302 are sleeved on the outer end of the high-voltage cable, the top end of the steel strands 302 is moved inside the fixed sleeve 301 by rotating the fixed plate 303. As the fixed plate 303 moves upward, the length of the steel strands 302 exposed on the outer end of the fixed sleeve 301 is adjusted simultaneously. Thus, the length of the steel strands 302 pulls the high-voltage cable upward during the adjustment and movement, thereby reducing the time and labor required for workers to adjust the height of the high-voltage cable and improving the practicality of the device.

[0030] The drive mechanism 4 includes a fixed rod 401, which is mounted on the upper surface of the fixed plate 303. The fixed rod 401 has a groove inside, and a push rod 402 is installed inside the groove. Specifically, by pushing the push rod 402, the fixed rod 401 and the fixed plate 303 are rotated inside the fixed sleeve 301. This allows the operator to adjust the position of the movable fixed plate 303 inside the fixed sleeve 301 without taking out tools, thereby reducing the time and labor required for adjusting the position of the movable fixed plate 303.

[0031] The connecting mechanism 5 includes a plug rod 502, and grooves are provided at the bottom hooks of the J-shaped hook 101 and the S-shaped hook 201. The outer contour of the plug rod 502 is adapted to the inner contour of the groove inside the J-shaped hook 101 and the S-shaped hook 201. A connecting rod 501 is installed at the top of the plug rod 502 and is installed on the outer surface of the fixed sleeve 301. Specifically, by pushing the plug rod 502, the plug rod 502 is inserted into the groove of the S-shaped hook 201 or the J-shaped hook 101, so that the connecting mechanism 5 restricts the movement position of the adjusting mechanism 3 sleeved on the outer end of the first suspension assembly 1 or the second suspension assembly 2, thereby minimizing the shaking of the adjusting mechanism 3 during use, thus improving the stability of the high-voltage cable during the suspension process.

[0032] The outer ends of both the first suspension assembly 1 and the second suspension assembly 2 are coated with anti-rust paint. Specifically, by applying anti-rust paint to the outer ends of the first suspension assembly 1 and the second suspension assembly 2, the anti-rust paint covers and protects the first suspension assembly 1 and the second suspension assembly 2, thereby minimizing the risk of corrosion after the first suspension assembly 1 and the second suspension assembly 2 are placed inside the mine for a long time, thus improving the service life of the first suspension assembly 1 and the second suspension assembly 2.

[0033] In summary: By pushing the S-hook 201, the top of the S-hook 201 is suspended to the outer end of the anchor rod. Then, by pushing the U-shaped locking block 203, the U-shaped locking block 203 is engaged with the two sets of slots in the arc-shaped positioning block 202. Finally, by rotating the bolt 204, the upper surface of the bolt 204 is pressed against the bottom of the anchor rod, thus securing the S-hook 201 to the outer end of the anchor rod. This eliminates the need for subsequent anchor rod driving into the well during the laying of high-voltage cables. By rotating the J-hook 101, the nut 104 is connected to the outer end of the anchor rod. Then, by pushing the J-hook 101... The position is adjusted and moved to a position perpendicular to the ground. The high-voltage cable is then suspended at the lower end of the J-shaped hook 101 using the adjustment mechanism 3. This ensures that the high-voltage cable is suspended at the same height during the suspension process, greatly improving the appearance and standardization of the cable hanging on site. Furthermore, the second suspension component 2 and the first suspension component 1 can be switched to suspend the high-voltage cable. This allows the device to change the position of the first suspension component 1 and the second suspension component 2 according to different suspension environments during subsequent use, thereby enabling the device to meet the requirements of long-distance high-voltage cable laying and hanging work underground.

[0034] Meanwhile, by rotating the fixing plate 303, the top end of the steel strand 302 moves inside the fixing sleeve 301, so that the length of the exposed end of the steel strand 302 outside the fixing sleeve 301 is adjusted synchronously during the upward movement of the fixing plate 303. In this way, the length of the steel strand 302 is adjusted and moved synchronously, pulling the high-voltage cable upward, thereby shortening the time and labor required for workers to adjust the height of the high-voltage cable.
