Description

Technical Field

[0001] The utility model relates to the technical field of power supply and distribution in open-pit mines, in particular to an underground cable trough for power supply and distribution in open-pit mines. Background Art

[0002] Cables are typically protected by cable protection tubes to extend their service life. These are mechanically strong metal tubes placed over the cables to prevent damage. They are primarily installed where communication cables and power lines intersect. They prevent power line breaks and short circuits, which could cause the communication cables and wire ropes to become live. They protect the cables, switches, and circuit boards, ultimately preventing damage to the entire device. They also provide some isolation from magnetic interference from the power lines.

[0003] According to a publicly disclosed underground cable protection trough (Announcement No.: CN216794528U), the protective cover in the above application is connected to the trough body using multiple sets of fixing nails. However, during the connection process, the operator is required to continuously align the protective cover with the bolt holes on the surface of the trough body and keep the alignment during the connection. The manual alignment method not only has certain deviations, but is also very easy to cause connection misalignment due to hand shaking during the fixing process. To address this problem, we have proposed an underground cable trough for power supply and distribution in open-pit mines. Utility Model Content

[0004] The purpose of the utility model is to provide an underground cable trough for power supply and distribution in open-pit mines, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an underground cable trough for power supply and distribution in open-pit mines, comprising a trough body and a protective cover, wherein a connecting block is fixedly installed on the inner wall of the trough body, and a positioning control component is provided in the trough body, and the control component comprises: a circular hole, which is provided on the surface of the protective cover, and a transverse hole is provided on the surface of the protective cover; a round block, a limiting rod is fixedly installed on the surface of the round block, thereby completing the initial connection between the protective cover and the trough body, and avoiding dislocation due to movement during subsequent connection.

[0006] Preferably, the control component also includes a positioning member, which includes: a round rod, which passes through the groove body and is rotatably connected to the groove body, and the surface of the round rod is fixedly connected to the surface of the round block. When the round rod rotates in the groove body, the round block fixed on the surface of the round rod can rotate synchronously.

[0007] Preferably, a threaded rod is fixedly installed at the bottom of the round rod, the threaded rod passes through the connecting block and is rotatably connected to the connecting block, the surface of the connecting block is rotatably connected to the surface of the circular plate, the surface of the circular plate is fixedly connected to the surface of the threaded rod, and when the threaded rod rotates under the action of the circular plate, the threaded rod can drive the round rod to rotate synchronously.

[0008] Preferably, a support plate is fixedly mounted on the surface of the circular plate, and a rotating block is fixedly mounted on the surface of the support plate. The rotating block can drive the circular plate to rotate on the surface of the connecting block through the support plate.

[0009] Preferably, a cross bar is fixedly installed on the inner wall of the circular plate, and the cross bar passes through the moving block and is slidably connected to the moving block. The surface of the moving block is fixedly connected to one end of the spring, and the other end of the spring is fixedly installed on the surface of the support plate. A clamping rod is fixedly installed on the surface of the moving block. When the moving block is squeezed, the moving block can squeeze the spring, and the clamping rod fixed on the surface of the moving block can slide synchronously.

[0010] Preferably, a circular ring is fixedly installed on the surface of the connecting block, and a protrusion is fixedly installed on the inner wall of the circular ring. The setting of the protrusion on the inner side of the circular ring can limit the swing of the clamping rod, so that the circular plate cannot rotate. This method can enhance the stability of the equipment during initial fixation.

[0011] Compared with the existing technology, the utility model provides an underground cable trough for power supply and distribution in open-pit mines, which has the following beneficial effects:

[0012] 1. The underground cable trough for power supply and distribution in open-pit mines is provided with a control component. The circular hole opened on the surface of the protective cover passes through the surface of the round rod. The round block fixed on the surface of the round rod and the limit rod are moved out of the protective cover along the horizontal hole. After moving out, the circular plate is rotated on the surface of the connecting block, and the circular plate drives the threaded rod to rotate synchronously. When the threaded rod rotates, the round rod fixed on the surface of the threaded rod rotates synchronously in the trough body. When the round rod rotates, the limit rod fixed on the surface of the circular block will form a staggered shape with the horizontal hole, thereby completing the initial connection between the protective cover and the trough body, avoiding dislocation due to movement during subsequent connection.

[0013] 2. The underground cable trough for power distribution in open-pit mines is equipped with positioning parts. When the circular plate rotates, the threaded rod fixed on the surface of the circular plate can rotate synchronously. When the moving block in the circular plate is not subjected to the squeezing force, the clamping rod fixed on the surface of the moving block will always be in the gap between the two groups of protrusions. The protrusions can limit the swing of the clamping rod, and the circular plate cannot rotate. This method can enhance the stability of the equipment during initial fixation.

DETAILED DESCRIPTION

[0020] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: an underground cable trough for power supply and distribution in open-pit mines, comprising a trough body 1 and a protective cover 3, a connecting block 2 being fixedly installed on the inner wall of the trough body 1, a positioning control component 4 being arranged in the trough body 1, and the control component 4 comprising: a circular hole 41, the circular hole 41 being opened on the surface of the protective cover 3, a transverse hole 42 being opened on the surface of the protective cover 3, a limiting rod 44 being fixedly installed on the surface of the circular block 43, when the circular plate 453 rotates, the circular plate 453 drives the threaded rod 452 to rotate synchronously, when the threaded rod 452 rotates, the circular rod 451 fixed on the surface of the threaded rod 452 rotates synchronously in the trough body 1, and when the circular rod 451 rotates, the limiting rod 44 fixed on the surface of the circular block 43 will form an interlaced shape with the transverse hole 42, thereby completing the preliminary connection between the protective cover 3 and the trough body 1, and avoiding dislocation due to movement during subsequent connection.

[0021] The control assembly 4 also includes a positioning member 45, which includes a round rod 451. The round rod 451 passes through the trough body 1 and is rotatably connected to the trough body 1. The surface of the round rod 451 is fixedly connected to the surface of the circular block 43. When the round rod 451 rotates in the trough body 1, the circular block 43 fixed to the surface of the round rod 451 can rotate synchronously. A threaded rod 452 is fixedly mounted on the bottom of the round rod 451. The threaded rod 452 passes through the connecting block 2 and is rotatably connected to the connecting block 2. The surface of the connecting block 2 is rotatably connected to the surface of the circular plate 453. The surface of the circular plate 453 is fixedly connected to the surface of the threaded rod 452. When the threaded rod 452 rotates under the action of the circular plate 453, the threaded rod 452 can drive the round rod 451 to rotate synchronously. A support plate 454 is fixedly mounted on the surface of the circular plate 453. A rotating block 455 is fixedly mounted on the surface of the support plate 454. The rotating block 455 can drive the circular plate 453 to rotate on the surface of the connecting block 2 through the support plate 454. A crossbar 456 is fixedly mounted on the inner wall of the circular plate 453. The crossbar 456 passes through the movable block 457 and is slidably connected to the movable block 457. The surface of the movable block 457 is fixedly connected to one end of a spring 458. The other end of the spring 458 is fixedly mounted on the surface of the support plate 454. A clamping rod 459 is fixedly mounted on the surface of the movable block 457. When the movable block 457 is squeezed, the movable block 457 can squeeze the spring 458, and the clamping rod 459 fixed to the surface of the movable block 457 can slide synchronously. A circular ring 4510 is fixedly mounted on the surface of the connecting block 2. A protrusion 4511 is fixedly mounted on the inner wall of the circular ring 4510. The setting of the protrusion 4511 inside the circular ring 4510 can limit the swing of the clamping rod 459, so that the circular plate 453 cannot rotate. This method can enhance the stability of the device after the initial fixation.

[0022] In the present invention, when the protective cover 3 needs to be connected to the trough body 1, the circular hole 41 opened on the surface of the protective cover 3 is passed through the surface of the round block 43, and the limiting rod 44 fixed on the surface of the round block 43 slides along the horizontal hole 42. After the protective cover 3 is fitted with the trough body 1, the moving block 457 is pressed, and the moving block 457 slides on the surface of the cross bar 456 to squeeze the spring 458. When the moving block 457 moves, the clamping rod 459 fixed on the surface of the moving block 457 can be moved out from the gap between the two sets of protrusions 4511. After moving out, the pressing force is maintained, and the circular plate 453 is driven to rotate through the rotating block 455 and the support plate 454. When the circular plate 453 rotates, the circular plate 453 drives the threaded rod 452 to rotate synchronously When the threaded rod 452 rotates, the round rod 451 fixed on the surface of the threaded rod 452 rotates synchronously in the groove body 1, and when the round rod 451 rotates, the limiting rod 44 fixed on the surface of the round block 43 will form an interlaced shape with the horizontal hole 42, thereby completing the initial connection between the protective cover 3 and the groove body 1, avoiding dislocation due to movement during subsequent connection. After fixation, release the pressing force, and the moving block 457 can bounce up under the support of the spring 458. When the moving block 457 bounces up, the card rod 459 fixed on the surface of the moving block 457 can move to the distance between the two groups of protrusions 4511. The protrusion 4511 can limit the swing of the card rod 459, and the circular plate 453 cannot rotate. This method can enhance the stability of the equipment during initial fixation.

[0023] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
