Description

Technical Field

[0001] This utility model relates to the field of moisture-proof technology for tunneling machine cables, specifically to an external moisture-proof device for tunneling machine cables. Background Technology

[0002] The cables of tunneling machines are crucial components for power supply and signal transmission during operation. Tunneling machine cables typically employ a double-sheath design, with the sheath material being imported flame-retardant polyurethane, reinforced with aramid (Kevlar) braid in the middle, and a metal tensile conductor inside the core wire. This design effectively solves problems such as short service life, easy core breakage, and easy sheath cracking in underground mining cables.

[0003] The present invention discloses a moisture-proof external device for the cable of a tunneling machine in publication number CN220042904U. Although the present invention has a novel design and reasonable structure, the first connecting part, the second connecting part and the fixing clip are set to facilitate the fixing of the external device box. The overall operation is simple and easy to install and disassemble.

[0004] However, the moisture-proof external cable protection for this tunneling machine has the following disadvantages:

[0005] (1) The cable moisture-proof external device of the tunneling machine has a weak fixing function. When using the device to prevent moisture in the cable, it is impossible to fix the cable, which may cause the cable to move and overlap, resulting in a decrease in the moisture-proof effect.

[0006] (2) The external moisture-proof device for the cable of the tunneling machine has a weak moisture-proof function. When in use, the device uses an external moisture-proof material box to protect the cable box from moisture, which may result in poor moisture-proof effect. Utility Model Content

[0007] The purpose of this utility model is to provide a moisture-proof external device for the cable of a tunneling machine to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a moisture-proof external device for the cable of a tunneling machine, comprising a cable box, a fixed plate fixedly connected to the top of the inner wall of the cable box, a sliding groove formed at the bottom of the fixed plate, a movable block slidably connected to the inner wall of the sliding groove, a circular slot formed on the side of the movable block, a spring A fixedly connected to the inner wall of the circular slot, a retaining ball fixedly connected to one end of the spring A, a connecting rod fixedly connected to the bottom of the movable block, fixed rings fixedly connected to both ends of the bottom of the connecting rod, a spring B fixedly connected to the inner side wall of the fixed ring, a clamping plate fixedly connected to one end of the spring B, a fixed frame fixedly connected to the top of the side of the cable box, a dustproof net fixedly connected to the outer surface of the fixed frame, a fan provided on the inner wall of the fixed frame, a protective net provided on the outer surface of the fan, and a dehumidifying box fixedly connected to the bottom of the side of the cable box.

[0009] Preferably, a connecting box is fixedly connected to the bottom of the cable box, and a transparent box is provided on the inner wall of the connecting box. The connecting box can reduce the entry of moisture near the ground into the cable box, and a desiccant can also be placed inside the transparent box.

[0010] Preferably, the cable box has a movable door rotatably connected to its front, and a handle is fixedly connected to the outer edge of the movable door, allowing workers to rotate the movable door by holding the handle.

[0011] Preferably, the inner wall of the spring A is provided with a telescopic rod A, one end of which is fixedly connected to the center of the back of the ball, and the telescopic rod A can prevent the spring A from tilting.

[0012] Preferably, the inner wall of the spring B is provided with a telescopic rod B, one end of which is fixedly connected to the center of the back of the clamping plate. The telescopic rod B can prevent the spring B from tilting.

[0013] Preferably, the inner wall of the sliding groove is provided with a slot, and the inner wall of the slot is engaged with one end of the ball, and the ball is engaged in the slot on the inner wall of the sliding groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The moisture-proof external device for the tunneling machine's cables, through the arrangement of a cable box, fixed plate, sliding groove, moving block, spring A, retaining balls, connecting rod, fixed ring, spring B, and clamping plate, allows the operator to insert the cable into the fixed ring during use. Spring B then presses against the clamping plate, causing it to hold the cable in place. Moving the moving block within the sliding groove on the fixed plate causes the retaining balls on both sides of the moving block to be pressed into the retaining grooves on the inner wall of the sliding groove by spring A. This causes the moving block to move the connecting rod, dispersing the cable within the clamping plate. This design improves the moisture-proof effect of the cables and enhances the stability and safety of the device.

[0016] 2. The cable moisture-proof external device of this tunneling machine is designed with a fixed frame, dustproof net, fan, protective net, and desiccant box. During use, the operator connects the device to an external power source and starts the fan inside the fixed frame. The fan draws air from outside the fixed frame, which then passes through the dustproof net and protective net into the device, accelerating airflow. The desiccant box contains desiccants and other materials. This design improves the device's moisture-proof effect on the cables. Attached Figure Description

A fan 13 is installed on the inner wall of the fixing frame 11. A protective net 14 is installed on the outer surface of the fan 13. A dehumidifying box 15 is fixedly connected to the bottom side of the cable box 1. The cable box 1, fixing plate 2, sliding groove 3, moving block 4, spring A5, and clamping ball 6 are connected. The arrangement of connecting rod 7, fixing ring 8, spring B9, and clamping plate 10 is as follows: During use, the operator inserts the cable into the fixing ring 8, allowing spring B9 to press against clamping plate 10, which then clamps the cable. Next, the moving block 4 in the sliding groove 3 on the fixing plate 2 is moved. The retaining balls 6 on both sides of the moving block 4 are pressed into the retaining grooves on the inner wall of the sliding groove 3 by spring A5, causing the moving block 4 to move the connecting rod 7, thus dispersing the cable within clamping plate 10. This arrangement improves the moisture-proof effect of the cable. This design improves the stability and safety of the device. With the installation of the fixed frame 11, dustproof net 12, fan 13, protective net 14, and dehumidification box 15, when in use, the operator connects the device to an external power source and starts the fan 13 inside the fixed frame 11. The fan 13 draws air from outside the fixed frame 11, which then passes through the dustproof net 12 and the protective net 14 into the device, accelerating the airflow inside. The dehumidification box 15 can contain desiccants and other materials. This design improves the device's moisture protection effect on cables.

[0024] A connecting box 16 is fixedly connected to the bottom of the cable box 1. A transparent box 17 is provided on the inner wall of the connecting box 16.
