Description

Technical Field

[0001] The utility model relates to the technical field of power transmission equipment, in particular to a cable box capable of preventing falling off. Background Art

[0002] In the current mining process, large equipment is usually used for excavation, and large equipment usually requires a large amount of electricity, which means a large number of cables are needed to power it. During the cable laying process, a large number of cable clamps are needed to fix and organize the cables to avoid the cables being arranged in a messy manner, which makes maintenance difficult, and to avoid damage to the cables caused by friction between the cables. The existing cable clamp (Chinese patent number: CN00206365.4) can make the cable slide toward the small end due to its own weight, driving the two conical wedges of the clamp group to go deeper into the conical hole of the clamp seat. The inclined surface effect of the conical hole of the clamp seat makes the two conical wedges clamp more tightly as they move toward the middle. However, the current situation is that when the cable is not subject to external force or is slightly disturbed, it is usually in a free state and will not slip. Long-term clamping of the cable will cause stress on the outer insulation layer of the cable, which will twist under slight external interference, causing the insulation layer to wear faster.

[0023] It should be noted that, in order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0024] Depend on Figure 1-2A cable box for preventing falling off is shown, comprising a clamping shell 1, the top surface of the clamping shell 1 being open and detachably connected to a cover plate 2, the opposite side walls of the inner cavity of the clamping shell 1 being fixedly connected to driving components, the two ends of the driving component being transmission-connected with clamping blocks 7, the top and bottom surfaces of the clamping block 7 being respectively provided with inclined surfaces, the clamping block 7 being slidingly connected to the driving block 8 through the inclined surfaces, and the driving block 8 being fixedly connected to the clamping shell 1; two clamping blocks 7 being close to each other are arranged opposite to each other and clamping grooves 9 are respectively provided on the opposite sides of the two clamping blocks 7, a cable 10 being abutted in the clamping groove 9; a fixing ring 11 is sleeved on the outside of the cable 10 and fixedly connected, and the fixing ring 11 is transmission-connected to the driving component.

[0025] A further optimized solution includes a drive assembly comprising a motor 12. This motor 12 is a dual-head automatic induction motor 12 with an integrated controller. This motor 12 can sense when it is blocked and unable to rotate, and can automatically stop by detecting a high current in the motor's rotor. This is prior art and will not be further described here. Furthermore, a PLC controller integrated into the motor 12 can sense the torque and rotation angle of the motor 12. The output shafts at both ends of the motor 12 are fixedly connected to screws 13, which penetrate the side of the clamping block 7 and are screwed to the clamping block 7. The motor 12 is slidably connected to the inner wall of the clamping shell 1. The outer side of the motor 12 is fixedly connected to a mounting block 14. A groove 15 is formed on one side of the mounting block 14. The opposite side walls of the groove 15 are fixedly connected to a first pole 16. The first pole 16 is detachably connected to a second pole 17. The second pole 17 is fixedly connected to the side wall of the fixing ring 11. The first pole 16 and the second pole 17 are respectively fixedly connected to and communicate with two power lines that control the start of the motor 12. The power lines are fixedly connected to and communicate with external power supply equipment or with batteries fixedly connected to the inner cavity of the clamping shell 1, so as to facilitate driving the motor 12. The first pole 16 and the second pole 17 are in contact, which can start the motor 12.

[0026] Further optimization of the scheme by Figure 3 As shown, the two ends of the bottom surface of the cover plate 2 are fixedly connected to the slide rails 3, and the two ends of the top surface of the clamping shell 1 are respectively provided with slide grooves that are compatible with the slide rails 3. The slide rails 3 are slidably connected to the slide grooves, which can cover the cover plate 2 on the top surface of the clamping shell 1 to protect the internal cables 10. The opposite sides of the cover plate 2 are respectively fixedly connected to the first latch 4, and the outer side of the first latch 4 is slidably connected to the connecting plate 6. One end of the connecting plate 6 is slidably connected to the second latch 5, and the second latch 5 is fixedly connected to the insertion rod 20. A socket is provided at one end of the top surface of the clamping shell 1. The insertion rod 20 is plugged into the socket on the top surface of the clamping shell 1, which can limit the cover plate 2 on the top surface of the clamping shell 1 and prevent the cover plate 2 from slipping off the clamping shell 1.

[0027] To further optimize the solution, an oblong groove 18 is provided on the side of the connecting plate 6, and the oblong groove 18 is slidingly connected to the first pin 4 and the second pin 5 respectively. The oblong groove 18 can flexibly adjust the distance between the first pin 4 and the second pin 5, so as to facilitate the insertion of the rod 20 into the socket.

[0028] Further optimization of the scheme by Figure 4 As shown, the side of the fixing ring 11 is provided with a wiring groove 19 for routing the power cord. The outer surface of the fixing ring 11 slides in contact with the groove 15 and is fixedly mounted on the side of the fixing ring 11. The second pole 17 is positioned opposite the first pole 16. The fixing ring 11 can be driven by the cable 10 to achieve contact between the first pole 16 and the second pole 17. The fixing ring 11 is made of an insulating resin or rubber material and is welded to the outer casing of the cable 10 using ultrasonic welding equipment.

[0029] As a further optimization solution, the clamping block 7 is made of rubber or silicone material, which is convenient for clamping cables 10 within a certain diameter range.

[0030] According to a further optimized solution, a plurality of slide posts 21 are fixedly connected to the side of the motor 12 , and the slide posts 21 pass through the side wall of the clamping shell 1 and are slidably connected to the clamping shell 1 .

[0031] The working process of this embodiment is as follows:

[0032] The cable 10 is routed between the four clamping blocks 7, and a fixing ring 11 is ultrasonically welded to the outer side of the cable 10. This fixing ring 11 not only secures the cable 10 in place, but also securely mounts the second pole 17 to control the start of the motor 12. After the cable 10 is installed, the slide rail 3 under the cover 2 is inserted into the slide groove, the clamping shell 1 is closed, and one end of the rod 20 is pulled up and inserted into the socket. The cover 2 is then positioned along the slide rail 3 using the connecting plate 6.

[0033] At this time, the cable 10 is pre-clamped under the action of the clamping block 7, so that the cable 10 and the clamping block 7 can slide relative to each other under the action of external force.

[0034] When the cable 10 slides a certain distance toward the drive block 8, the first pole 16 and the second pole 17 come into contact, and the motor 12 starts, driving the screws 13 at both ends to drive the corresponding clamping blocks 7 to move away from each other. Under the action of the corresponding drive blocks 8, the two clamping blocks 7 will move toward the center of the clamping shell 1, thereby clamping the cable 10 until the motor 12 is controlled by the controller to stop rotating due to the clamping force. Furthermore, in order to prevent the cable 10 from being squeezed by external force for a long time, when the cable 10 is squeezed by the clamping block 7 with a certain intensity for a certain period of time, the motor 12 will be driven in the reverse direction to initialize the pre-tightening force of the clamping block 7. When the cable 10 is pulled by external force again, the above steps will be repeated, and the drive motor 12 will clamp again.

[0035] The above are merely preferred embodiments of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
