Description

Technical Field

[0001] This utility model belongs to the field of cable laying technology, specifically a portable cable laying device. Background Technology

[0002] During the construction of cable lines, cable laying is the most important construction process. In particular, cable laying in tunnels requires the use of a large number of cable conveyors, cable pulleys, control equipment and other equipment for ground laying. After the ground laying is completed, the cables are then manually moved to the cable supports and finally adjusted for serpentine laying.

[0003] Traditional methods of laying cables in tunnels have the following disadvantages:

[0004] 1. Placing all laying equipment on the ground during the laying process blocked the construction passage, making it inconvenient to inspect the laying process and also preventing the transfer of other tools and materials, thus affecting the overall construction schedule.

[0005] 2. The number of workers required during the cable laying process is only half that required for cable racking and serpentine laying adjustments after the laying is completed. The difference in the number of workers required before and after the laying process leads to a waste of human resources.

[0006] 3. As tunnel cross-sections increase, cable placement heights also gradually increase. When manually handling cables with larger cross-sections, the risk of cables falling and causing cable damage and personnel injury also increases accordingly. Utility Model Content

[0007] The main objective of this invention is to provide a portable cable laying device that requires little space and manpower.

[0008] The portable cable laying device provided by this utility model includes a drive wheel and an auxiliary wheel that can clamp the cable, and the distance between the drive wheel and the auxiliary wheel is adjustable; the drive wheel and the auxiliary wheel are fixed on the base frame.

[0009] In one embodiment of the above device, the drive wheel is a roller with a small radius in the middle and large radii at both ends; the two ends of the drive wheel are connected to the two wings of the U-shaped base by bearings.

[0010] In one embodiment of the above-mentioned device, the drive wheel has a built-in motor, which drives the drive wheel to rotate via a motor drive shaft.

[0011] In one embodiment of the above-mentioned device, the two wings of the base are hollow and open upwards; the two wings have holes at fixed intervals.

[0012] In one embodiment of the above device, the auxiliary wheel is a roller with a small radius in the middle and large radii at both ends, but the radius of the auxiliary wheel is smaller than that of the driving wheel.

[0013] In one embodiment of the above device, L-shaped connecting plates are fixed at both ends of the auxiliary wheel, and holes are opened on the connecting plates at fixed intervals.

[0014] In one embodiment of the above-mentioned device, the bottom end of the connecting plate is inserted into the side wing of the base, and the connecting plate and the side wing are fastened together by two sets of connectors.

[0015] In one embodiment of the above-mentioned device, the base frame includes four legs and a top frame, and the base is fixed on the base frame.

[0016] In one embodiment of the above-mentioned device, a short plate that increases friction is fixed to the bottom end of the support leg of the base frame.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. Install this device on the bracket when the cable is in place. When the cable is in place, simply move the cable to the inside of the bracket, reducing the handling height, reducing the amount of handling work, requiring less manpower, and increasing work efficiency.

[0019] 2. Laying the cable at its final location can prevent it from falling during handling and installation, thus mitigating the risk of injury to personnel.

[0023] The relevant technical solutions will now be clearly and completely described with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] Combination Figure 1 and Figure 2 As can be seen, the portable cable laying device disclosed in this embodiment includes a drive wheel 1, a base 2, an auxiliary wheel 3, a connecting plate 4, and a base frame 5.

[0025] The drive wheel 1 is a roller with a small radius in the middle and large radii at both ends. The two ends of the drive wheel are connected to the two wings of the U-shaped base 2 by bearings. The drive wheel has a built-in motor, which drives the drive wheel to rotate through the motor drive shaft to provide output torque.

[0026] The two wings of the base 2 are hollow and open upwards. There are holes at fixed intervals on the two wings.

[0027] The auxiliary wheel 3 is a roller with a similar shape to the driving wheel 1, but with a smaller radius in the middle and larger radii at both ends. However, the radius of the auxiliary wheel is smaller than that of the driving wheel.

[0028] L-shaped connecting plates 4 are fixed to both ends of the auxiliary wheel 3, and holes are opened on the connecting plates at fixed intervals. The bottom end of the connecting plate can be inserted into the side wing of the base 2, and the connecting plate and the side wing are fastened and fixed by two sets of bolts.

[0029] When in use, the height of the connecting plate is adjusted to create a clamping force between the auxiliary wheel and the drive wheel, and the combined force of the drive wheel and the auxiliary wheel drives the cable laying.

[0030] The base frame 5 includes four legs and a top frame, with the base 2 fixed to the base frame. The bottom of the legs of the base frame is fixed with a short plate to increase friction and maintain stability.

[0031] When using this device:

[0032] 1. Preparation: Transport all components of this device to the cable laying site; confirm that all components of the laying device are intact, including the drive wheel, base, auxiliary wheel, connecting plate and base frame.

[0033] 2. Device installation: Place the base frame on the cable support, ensuring that the short plates at the bottom of its four legs can increase friction and maintain the stability of the device; then fix the base on the base frame and fasten the base to the base frame with bolts.

[0034] 3. Auxiliary wheel height adjustment: Adjust the height of the auxiliary wheel according to the cable diameter; the specific operation is to insert the bottom end of the connecting plate into the side wing of the base, and adjust the height of the auxiliary wheel by adjusting the insertion depth; fasten the connecting plate and the side wing with two sets of bolts to ensure that the distance between the auxiliary wheel and the drive wheel forms a suitable clamping force.

[0035] 4. Cable laying: Move one end of the cable to the inside of the bracket so that it is aligned with the drive wheel and auxiliary wheel of the portable cable laying device; start the motor built into the device, and drive the drive wheel to rotate through the motor drive shaft. The drive wheel and auxiliary wheel work together to lay the cable; ensure that the cable is laid in the final position and prevent the cable from falling during the process of loading and transporting it.

[0036] 5. Process monitoring and adjustment: During the laying process, monitor the laying status of the cable at any time to ensure that the cable passes through the device smoothly and steadily; if the cable deviates or gets stuck, the height of the auxiliary wheel or the clamping force can be adjusted in time to ensure that the cable is laid smoothly.

[0037] 6. Completion of Laying: After the cable laying is completed, turn off the motor, remove the cable from the device, and make necessary serpentine laying adjustments. Remove the portable cable laying device from the cable support and move it to the next laying point or store it.

[0038] The advantages of using this device are as follows:

[0039] 1. Install this device on the bracket when the cable is in place. When the cable is in place, simply move the cable to the inside of the bracket, reducing the handling height, reducing the amount of handling work, requiring less manpower, and increasing work efficiency.

[0040] 2. Laying the cable at its final location can prevent it from falling during handling and installation, thus mitigating the risk of injury to personnel.

[0041] 3. Installing the laying device on the support frees up ground equipment, avoiding the problem of blocking the construction passage when using traditional cable conveyors, saving tunnel space, and providing convenience for inspection, construction, and transportation of other tools and materials during the laying process.
