Description

Technical Field

[0001] The utility model belongs to the technical field of power supply and distribution installation tools, and specifically relates to a simple tool for cable laying. Background Art

[0002] Cable laying is an important step in providing power support for equipment, control, lighting, etc. in steel plants, and is directly related to the normal operation of the production line. All steel plant construction or power supply and distribution projects are inseparable from the laying of cable trays. Cable trays are used as structural support systems inside or outside buildings to carry, protect and manage power cables, communication equipment, pipelines and other lines. They are often mounted on walls or roofs, and can suspend cables and pipelines from the ground or other places without affecting people's passage or occupying the ground. When it is necessary to lay cables in a bridge, especially when thicker cables need to be laid in a high bridge, at least one construction worker needs to use a ladder to climb up, and at least one construction worker on the ground needs to hold the ladder to prevent falling. After the construction worker at the high position pulls a section of cable on the ground cable rack into the bridge slot, he needs to move the ladder section by section along the bridge to continue laying. This not only requires the cooperation of multiple construction or maintenance personnel, but also the personnel standing on the ladder to lay thick cables cannot exert their strength, which can easily cause the ladder to become unstable and pose a safety hazard. In addition, the construction workers have to climb up and down during the movement section by section, and there are obstructions such as load-bearing walls in some places, which is extremely inconvenient and affects work efficiency. Therefore, it is necessary to design a simple tool for laying cables. Utility Model Content

[0003] The utility model aims to solve at least one of the above technical problems to a certain extent. The utility model provides a simple tool for cable laying, which can reduce the required operators and improve the safety and efficiency of cable laying operations.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0033] Aiming at the problems of poor safety and working efficiency caused by the need for multiple people to cooperate and climb step by step during the cable laying in the cable tray 5 in the prior art, as Figure 1 and 2 shown, it is a preferred embodiment of the simple tool for cable laying described in the present utility model. The simple tool for cable laying includes a pulling support 1 and a moving trolley 2. The pulling support 1 can pull the moving trolley 2 to move along the cable laying direction. The pulling support 1 includes a first support 11 and a second support 12. The first support 11 extends downward, and the second support 12 extends forward of the moving trolley 2. One of the second support 12 and the moving trolley 2 is provided with a hook 16 that cooperates with the other. An upwardly opening support groove 3 is provided on the second support 12 and / or the moving trolley 2. The support groove 3 is used to support and limit the lateral movement of the cable 4 in the moving direction of the moving trolley 2.

[0034] As Figure 1 shown, the operator 6 can first climb up with a ladder, insert the moving trolley 2 from below the head end of the cable 4 and place it above the cable tray 5. The moving trolley 2 cooperates with the cable tray 5 and can slide along the cable tray 5. After the operator 6 gets off the ladder, as Figure 2 and Figure 3 shown, taking the example that the hook 16 and the support groove 3 are provided on the second support 12, the operator 6 on the ground can lift the pulling support 1, place the second support 12 above the cable tray 5 and in front of the moving trolley 2, fork up the cable 4 to be laid with the support groove 3, and then hang the hook 16 on the moving trolley 2. If the bottom of the cable tray 5 is a hollow structure, this step can be directly operated visually by the operator 6 on the ground. If the bottom of the cable tray 5 is blocked, this step can also hang the hook 16 on the moving trolley 2 in advance when installing the moving trolley 2.

[0035] As Figure 1 shown, when the operator 6 on the ground holds the pulling support 1 and moves along the extending direction of the cable tray 5, the moving trolley 2 can be pulled to move along the cable tray 5, that is, along the cable laying direction. Since the support groove 3 restricts the left - right movement of the cable 4, during the movement of the pulling support 1 and the moving trolley 2, the cable 4 that has fallen to the ground can be gradually straightened and laid into the cable tray 5 for rapid laying.

[0036] Compared with the existing method that requires personnel to work at heights and multiple personnel to assist in escalator operations, after applying this tool, only one or two operators are needed, which can significantly reduce the number of required operators; compared with the existing safety hazards of high-altitude operations caused by personnel pulling cables, the operators can work at low altitudes, which plays a very good protective role in personnel maintenance safety; compared with the existing method of moving ladders section by section, the operators can lay cables continuously; when facing obstacles such as load-bearing walls, the space required for the pulling bracket 1 is smaller than that of a ladder, and it can drive the moving trolley 2 forward. At the same time, compared with the method of pulling ropes, the pulling bracket 1 composed of the first bracket 11 and the second bracket 12 is more convenient to quickly unhook the hook 16 on one side of the obstacle and then continue to lay the cable from the hook 16 on the other side of the obstacle, which is convenient for operation; compared with directly forking the cable 4 with the pulling bracket 1, the load-bearing of the cable 4 is mainly on the moving trolley 2, making it easier for the operators below to pull; thus greatly improving the efficiency of laying the cable 4, which is fast, convenient and safe; after the laying is completed, the pulling bracket 1 and the moving trolley 2 can also be separated and stored for flexible application, which has promotional significance.

[0037] Preferably, the first bracket 11 includes at least one telescopic joint 110. Compared with the bracket structure with an unadjustable length, the purpose of applying the telescopic joint 110 is to facilitate the adjustment of the height of the first bracket 11. When facing operators 6 and bridge frames 5 at different heights, the height of the first bracket 11 can be adjusted through the telescopic joint 110, which is more convenient for flexible operation.

[0038] Preferably, as Figure 4 shown, the telescopic joint 110 includes an outer tube 111, an inner part 112 and a locking joint 113. The inner part 112 is nested inside the outer tube 111, and the locking joint 113 is used to lock the outer tube 111 and the inner part 112; for example: the locking joint 113 includes a lock head 114 and a lock sleeve 115. The lock head 114 is provided with several pressing pieces 116, and the lock head 114 and the lock sleeve 115 are provided with mating threads 117. After the lock head 114 is installed at the end of the outer tube 111, the inner part 112 can be made of pipe fittings, which is lighter in weight and more convenient for operation. The lock sleeve 115 is sleeved outside the inner part 112. When the inner part 112 is inserted into the outer tube 111 between several pressing pieces 116 until the overall height is appropriate, then the lock sleeve 115 and the lock head 114 are screwed tightly, and the lock sleeve 115 presses and holds the pressing pieces 116 to hold the inner part 112, thus realizing the locking of the outer tube 111 and the inner part 112. Similarly, after the lock sleeve 115 is removed, the pressing pieces 116 open, and the length of the inner part 112 extending into the outer tube 111 can be adjusted again, so as to realize the arbitrary expansion and contraction of the telescopic joint 110, which is more convenient for adjustment.

[0039] Preferably, as Figure 3As shown, the first bracket 11 is hinged to the second bracket 12. A locking nut 15 is provided on the hinge axis 14 of the first bracket 11 and the second bracket 12. After loosening the locking nut 15, the first bracket 11 and the second bracket 12 can rotate relative to each other to adjust the angle, and then the locking nut 15 is used to lock the hinge axis 14, thereby locking the angles of the first bracket 11 and the second bracket 12. For example, when the first bracket 11 and the second bracket 12 are perpendicular, it is convenient for the second bracket 12 to extend in front of the mobile trolley 2. When both the first bracket 11 and the second bracket 12 are vertical, the space can be reduced, facilitating the storage of the traction bracket 1.

[0040] Preferably, a hanging ring 201 matching the hook 16 is provided on the second bracket 12 or the mobile trolley 2; as Figure 3 shown, for example: multiple hanging rings 201 can be provided on the mobile trolley 2, and the hook 16 on the second bracket 12 can hook down the corresponding hanging ring 201, facilitating the hooking and unhooking operations of the hook 16; similarly, when the hanging ring 201 is provided on the second bracket 12 and the hook 16 is provided on the mobile trolley 2, during operation, the traction bracket 1 can be held up and the hanging ring 201 can be used to hook the hook 16.

[0041] Preferably, a U-shaped bracket 13 is provided on the second bracket 12 and / or the mobile trolley 2, and the opening of the U-shaped bracket 13 serves as the support groove 3; as Figure 3 shown, for example: the bottom of the U-shaped bracket 13 is detachably connected to the second bracket 12 by bolts, making it more convenient to disassemble and replace U-shaped brackets 13 of different widths according to the width requirements of laying the cable 4.

[0042] Preferably, as Figure 3 shown, soft padding layers 202 are provided on the surface of the support groove 3 and the front part of the mobile trolley 2. The soft padding layers 202 can be made of one or more layers of elastic materials such as sponge and rubber, and are adhesively connected to the support groove 3 and the mobile trolley 2. The purpose is to use the soft padding layers 202 at the support positions to avoid abrasion of the cable 4 skin during the sliding process.

[0043] Preferably, as Figure 3 shown, the mobile trolley 2 has an opening at the back, which is more convenient for the cable 4 behind the mobile trolley 2 to quickly drop onto the cable tray 5, and is also more convenient for reducing the self-weight of the mobile trolley 2 and facilitating the operation.

[0044] Preferably, pulleys 203 are provided on both sides of the mobile trolley 2. As Figure 3 shown, the pulleys 203 can be slidably mated with the cable tray 5 of the cable 4. During the operation, the rolling friction between the pulleys 203 and the cable tray 5 can be used to reduce the resistance, facilitating movement and saving effort.

[0045] The series of detailed descriptions listed above are only specific descriptions of the feasible embodiments of the present utility model, and they are not intended to limit the protection scope of the present utility model. Any equivalent embodiments or modifications made without departing from the technical spirit of the present utility model shall be included within the protection scope of the present utility model.
