Description

Technical Field

[0001] This utility model relates to the field of tunneling equipment technology, specifically to a unit cable auxiliary device. Background Technology

[0002] During tunneling operations, especially during coal cutting, the arrangement and protection of cables often become a source of safety hazards. Typically, cables are routed through cable trays or suspended from steel wire ropes on the roof to ensure the normal operation of power, signal, and other systems, supporting the tunneling equipment. However, due to the complexity of cable arrangement and the special construction environment, improper suspension methods or loose cables and suspension devices can easily cause cables to fall off. If cables are not properly secured or are loose, falling to the ground not only hinders construction progress, causing workers to trip or damaging the cables, requiring time and resources for repair and replacement, thus affecting overall production efficiency, but also, due to the random movement inherent in tunneling work, when cables are pulled a certain distance, they can affect the normal operation of the equipment, preventing further tunneling. As the tunneling equipment continues to move, cables can become stuck in rocks or other obstacles, affecting not only the cable's normal operation but also damaging the equipment. During tunneling, friction between the cable and the surrounding environment can cause wear and even breakage of the outer sheath, leading to power outages or signal failures. Utility Model Content

[0003] The purpose of this utility model is to provide a unit cable auxiliary device to solve the problems of complex short cable layout, special construction environment, improper hanging method or loose cable and hanging device, which can easily cause the cable to fall off. If the cable is not properly fixed or is loose, when the cable falls to the ground, it will not only hinder the construction progress, but also cause workers to trip or the cable to be damaged. Since the tunneling work has random mobility, when the cable is pulled to a certain distance, it will affect the normal operation of the equipment and make it impossible to continue the tunneling operation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a unit cable auxiliary device, comprising a monorail beam, a connecting plate, trolleys, a protective chain, a clamping device, and cables. The monorail beam is connected to the top of the tunnel and is arranged in an I-shape. Several trolleys are evenly distributed on the monorail beam. The bottom end of each trolley has a groove, and a rotating shaft is connected to the groove. A protective chain is provided between every two trolleys. A collar is connected to each of the two ends of the protective chain. The collar is fitted onto the rotating shaft. Connecting rings are symmetrically arranged on the left and right sides of the collar. A vertically erected fixing rod is connected to the bottom end of each connecting ring. A clamping device is connected to the bottom end of each fixing rod.

[0005] The clamping device includes a housing, a slider, a threaded rod, and an adjusting wheel. The housing is a rectangular groove with symmetrical grooves on its upper and lower sides. Two sliders are installed in the grooves and slide against the housing. A cable is installed between the two sliders. Connecting holes are symmetrically installed on the left and right sides of the housing. The connecting holes have internal threads and threaded rods are installed in them. The external threads of the threaded rods cooperate with the internal threads. The threaded rods pass through the connecting holes, with one end connected to the slider and the other end connected to the adjusting wheel.

[0006] Preferably, a connecting plate is provided between the monorail beam and the top of the tunnel. Several connecting columns are evenly distributed at the top of the monorail beam. The top of the connecting columns is connected to the connecting plate. Several through holes are evenly opened on the connecting plate. Connecting bolts are provided in the through holes. The connecting bolts pass through the through holes and connect to the top of the tunnel, and are fastened with nuts.

[0007] Preferably, the trolley is U-shaped and slides on a monorail beam. The top end of the U-shape has a transversely extending extension between the corresponding end faces, and the cut-off ends of the extension are respectively located in the grooves on the left and right sides of the monorail beam.

[0008] Preferably, a plurality of fixing blocks are evenly distributed on the outer circumference of the adjusting wheel, and positioning holes are provided on the fixing blocks. Limiting holes are provided on the left and right end faces of the outer shell corresponding to the positioning holes. Limiting screws are inserted into the positioning holes, the limiting screws pass through the fixing blocks, and the bottom end abuts against the inner wall of the limiting hole and is fastened by nuts.

[0009] Preferably, the contact end between the threaded rod and the slider is connected to a bearing seat.

[0010] Preferably, the corresponding end faces of the two sliders are respectively provided with arc-shaped grooves, and the arc-shaped ends abut against the outer circumference of the cable.

[0011] Preferably, the contact end between the trolley and the monorail beam is provided with rollers.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] A monorail lifting beam is installed at the top of the tunnel face, and trolleys are fixed to the beam via a connecting device. The trolleys are connected by protective chains to ensure synchronous movement. At the bottom of the trolleys, a cable clamping device is installed, consisting of sliders on both sides. The cable is securely fixed by the clamping structure between the sliders. The position of the clamping device is adjusted by rotating a threaded rod. The threaded rod engages with the internal thread on the outer shell, thereby moving the sliders. When the arc-shaped end of the slider is in contact with the outer circumference of the cable, the clamping device automatically determines the cable's position and locks the threaded rod in the positioning hole of the adjusting wheel via a limit screw, preventing further movement of the slider and ensuring secure cable clamping.

[0014] During tunneling, as the tunneling machine advances, the cable is pulled along, while the trolley slides along the monorail beam. A protective chain ensures that multiple trolleys move synchronously, keeping the cable in the correct position at all times, preventing it from dragging on the ground or becoming tangled, and ensuring smooth construction. Furthermore, a clamping device, via a connecting ring fitted onto a rotating shaft at the bottom of the trolley, allows the cable to rotate flexibly during movement, thus preventing tension or friction caused by changes in cable angle and preventing cable damage.

[0015] This improved solution effectively avoids various problems caused by placing cables directly on the ground, such as workers tripping or cable damage. At the same time, the slider adjustment function ensures that the cable remains in good condition during tunneling operations, automatically adjusting its position as the equipment moves, thus improving work efficiency and ensuring construction safety.

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: Please refer to Figure 1-4This utility model provides an embodiment of a unit cable auxiliary device, including a monorail beam 1, a connecting plate 2, a trolley 3, a protective chain 4, a clamping device 5, and a cable 6. The monorail beam 1 is connected to the top of the tunnel and serves as the core load-bearing structure of the hoisting system. It is I-shaped and provides support for the entire system, bearing the loads from components such as the trolley 3 and the clamping device 5. The monorail beam 1 is I-shaped, and several trolleys 3 are evenly distributed on it. The trolleys 3 are the moving parts of the hoisting system. The hoisting cable 6 slides along the monorail beam 1, allowing it to move synchronously with the tunneling machine. A groove is provided at the bottom of each trolley 3, and a rotating shaft is connected within the groove. A protective chain 4 connects every two trolleys 3, linking them together. When the cable 6 is pulled forward, one trolley 3 slides on the monorail beam 1. When the front trolley 3 moves forward, the cable 6 is pulled... The protective chain 4, when reaching its maximum stroke, pulls the second trolley 3 to move, allowing the cable 6 to move synchronously with the tunneling machine. Both ends of the protective chain 4 are connected to collars 7, which are connected to the trolleys 3. This design allows the protective chain 4 to rotate when pulled, and simultaneously, through the collars 7 and the rotating shaft, it pulls the subsequent trolley 3. The collars 7 are fitted onto the rotating shaft. Connecting rings 8 are symmetrically arranged on both sides of the collars 7. The purpose of the connecting rings 8 is to provide rotation for the clamping device 5 during operation. Vertically erected fixing rods are connected to the bottom ends of the connecting rings 8, and the clamping device 5 is connected to the bottom ends of the fixing rods.

[0026] The clamping device 5 includes a housing 501, sliders 502, a threaded rod 503, and an adjusting wheel 504. The housing 501 is a rectangular groove. Symmetrical grooves are formed on both the upper and lower ends of the housing 501. Two sliders 502 are housed within these grooves, and a cable 6 is positioned between the two sliders 502. By changing the distance between the corresponding end faces of the two sliders 502, cables 6 of different specifications can be clamped. The sliders 502 slide against the housing 501. Arc-shaped grooves are formed on the corresponding end faces of the two sliders 502, with the arc-shaped ends abutting against the outer circumference of the cable 6. The arc-shaped grooves fit snugly against the outer circumference of the cable 6, preventing damage to the cable 6 and providing a stable clamping grip.

[0027] Symmetrical connecting holes are provided on the left and right end faces of the outer casing 501. Internal threads are provided within these connecting holes, and threaded rods 503 are installed within them. When the threaded rod 503 rotates, the external thread engages with the internal thread, simultaneously sliding to move the slider 502 and clamp and fix the cable 6. The external and internal threads of the threaded rod 503 cooperate in their operation. The threaded rod 503 passes through the connecting holes, with one end connected to the slider 502 and the other end connected to an adjusting wheel 504. The adjusting wheel 504 facilitates the rotation of the threaded rod 503. A bearing seat is connected to the contact end between the threaded rod 503 and the slider 502, providing the rotational support for the threaded rod 503.

[0028] A connecting plate 2 is installed between the monorail lifting beam 1 and the top of the tunnel. The connecting plate 2 is located between the monorail lifting beam 1 and the tunnel top and is used to fix the monorail lifting beam 1. The connecting plate 2 is connected to the lifting beam via connecting columns, and then the entire lifting system is securely connected to the tunnel top using connecting bolts and nuts. The connecting plate 2 provides a robust connection structure, ensuring that the monorail lifting beam 1 does not shift or sway, thus enhancing the stability and reliability of the system. Several connecting columns are evenly distributed at the top of the monorail lifting beam 1, and the top of each column is connected to the connecting plate 2. Several through holes are evenly distributed on the connecting plate 2, and connecting bolts are installed in these through holes. The connecting bolts pass through the through holes and connect to the tunnel top, and are secured with nuts.

[0029] The trolley 3 is U-shaped and slides on the monorail beam 1. A laterally extending portion is provided between the top faces of the U-shaped end. The ends of the extending portion are respectively located in the grooves on the left and right sides of the monorail beam 1. Rollers are provided at the contact ends between the trolley 3 and the monorail beam 1. The use of rollers makes the movement of the trolley 3 smoother, reduces friction, and improves operating efficiency.

[0030] In use, the monorail beam 1 is first suspended in the tunnel via the connecting plate 2. Then, the trolley 3 is installed on the monorail beam 1. The trolleys 3 are then connected by the protective chain 4. The threaded rod 503 of the clamping device 5 is rotated, causing the slider 502 to slide within the housing 501. The distance between the two sliders 502 is adjusted. After the cable 6 is placed in, the arc-shaped end of the threaded rod 503 and the slider 502 are rotated to fit against the outer circumference of the cable 6 for clamping. When the tunneling machine moves forward, the cable 6 moves forward synchronously. At the same time, when the trolley 3 moves, the protective chain 4 is pulled. After the maximum stroke of the protective chain 4 is reached, the subsequent trolley 3 is pulled forward, so that the cable 6 can move forward synchronously with the tunneling machine.

[0031] Example 2: Please refer to Figure 2-3 Based on Example 1, it also has the following structure:

[0032] Several fixing blocks 505 are evenly distributed on the outer circumference of the adjusting wheel 504. The fixing blocks 505 are provided with positioning holes. Limiting holes are provided on the left and right end faces of the outer shell 501 corresponding to the positioning holes. Limiting screws 506 are inserted into the positioning holes. The limiting screws 506 pass through the fixing blocks 505, and the bottom end abuts against the inner wall of the limiting hole and is fastened by nuts. In order to ensure that the slider 502 loosens after clamping the cable 6, after the slider 502 is clamped, the limiting screws 506 are inserted into the positioning holes of the fixing blocks 505 of the adjusting wheel 504, with the bottom end inserted into the limiting hole and fastened by nuts to prevent it from loosening or displacing due to external force or vibration.

[0033] The above description is merely an embodiment of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model.
