Description

Technical Field

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

[0002] In fields such as power construction and telecommunications engineering, cable laying frames are indispensable equipment, and their performance directly affects the efficiency and safety of cable laying operations. Currently, cable laying frames on the market have several shortcomings: First, the main body of traditional laying frames is mostly made of heavy steel, resulting in a large overall weight. This not only makes them inconvenient to move but also increases the labor intensity of workers. Especially when working in complex outdoor terrain, the installation and disassembly of cable reels are difficult, significantly limiting flexibility. Second, the tension adjustment effect during the laying process is poor. Some laying frames lack effective tension control components, leading to inconsistent laying speeds and problems such as cable slack, tangling, or excessive stretching, affecting construction quality, resulting in high manufacturing costs and poor versatility. Utility Model Content

[0003] The purpose of this utility model is to provide a cable laying rack to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A cable laying rack, comprising:

[0006] The main body of the support frame is made of square tubing and includes two sets of triangular frames connected at the bottom front ends;

[0007] A cable reel is mounted on the top of two sets of triangular frames to support the cable reel.

[0008] A tension adjustment component is installed on one side of the pay-off shaft and the support body to adjust the speed of the pay-off shaft and ensure pay-off stability.

[0009] The triangular frame is an obtuse triangle. The two sets of triangular frames are connected by a front crossbar and two connecting rods. The front crossbar is located at the bottom front end of the two sets of triangular frames. The two connecting rods are located on the two frame rods at the bottom front end of the two sets of triangular frames respectively. The top of the two sets of triangular frames extends upward and is fixedly installed with a U-shaped support frame for placing the wire feeding shaft.

[0010] Multiple anti-reverse blocks are evenly installed on the lower surface of the front crossbar.

[0011] The cable feeding shaft is fitted with two sleeves for positioning and installing cable reels, and the sleeves are T-shaped sleeves.

[0012] One end of the pay-off shaft is provided with a mounting plate for installing the tension adjustment component, and the mounting plate is located outside the triangular frame.

[0013] A side plate is installed on the side of the pay-off shaft near the mounting plate. The side plate has through holes for inserting and installing the grip. The side plate is located between two sets of triangular frames.

[0014] The tension adjustment assembly includes a meshing linkage gear a and a linkage gear b. The linkage gear a is mounted on the mounting plate, and the linkage gear b is rotatably mounted on the fixed shaft of the mounting base. The mounting base is located on the top side wall of the triangular frame near the mounting plate, and a clamping assembly is mounted on the outside of the linkage gear b.

[0015] The clamping assembly includes a clamping spring and a spring plate, both of which are sleeved on the fixed shaft. A rotating nut is threaded to the end of the fixed shaft. The clamping spring is located between the rotating nut and the spring plate. A set of friction plates is installed on the side of the spring plate away from the clamping spring, and these friction plates abut against the linkage gear b.

[0016] The tension adjustment assembly includes a pulley and a pull rope. The pulley is fixedly mounted on the mounting plate, and the pull rope is wound around the pulley. Both ends of the pull rope are fixedly mounted on the crossbar sidewall of the triangular frame near the mounting plate.

[0017] The pull rope is a non-elastic rope, with a return spring at one end. The end of the return spring away from the pull rope is fixedly installed on the side wall of the crossbar of the triangular frame.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] 1) By using square tubing as the main material for the support frame, the overall weight of the cable tray is significantly reduced compared to the traditional heavy steel cable tray, greatly reducing the burden of handling by the staff and improving the flexibility of operation in complex terrain. At the same time, the use of a triangular frame facilitates the lever-type installation of the cable reel, making the cable tray operation faster and easier.

[0020] 2) By setting tension adjustment components on the main body of the support, the problem of unstable tension in traditional cable laying frame is effectively solved. It can adapt to the cable laying requirements of different specifications of cables, ensure that the cable maintains constant tension during the laying process, and reduce slack, tangling or overstretching.

[0021] 3) By setting a backstop block on the lower surface of the front crossbar, the main body of the support can be prevented from moving accidentally when the cable reel is empty, and it is also convenient for workers to lift the front crossbar to quickly pick up and put away the cable reel, which significantly improves the ease of operation.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] Example 1

[0031] like Figure 1-3 As shown, the cable laying frame of this utility model includes a support body, a laying shaft 4, and a tension adjustment assembly. The support body comprises two sets of triangular frames 6, each a blunt-angled triangle. The two sets of triangular frames 6 are connected by a front crossbar 1 and two connecting rods 10. The front crossbar 1 is located at the bottom front end of both sets of triangular frames 6, and the two connecting rods 10 are respectively located on two frame rods at the bottom front end of the two sets of triangular frames 6. The angles and side lengths of the two sets of triangular frames are designed according to the lever principle. A U-shaped support frame is fixedly installed at the top of each set of triangular frames 6, and the laying shaft 4 is mounted on the U-shaped support frame.

[0032] Two sleeves 5, T-shaped bushings, are fitted onto the pay-off shaft 4 to position and install the cable reel. The two sleeves 5 clamp and position the cable reel on the pay-off shaft 4. One end of the pay-off shaft 4 is equipped with a mounting plate 17 for installing a tension adjustment component. The mounting plate 17 is located outside the triangular frame 6 and has several threaded holes. A side plate 3 is installed on the pay-off shaft 4 near the mounting plate 17. The side plate 3 is located between the two sets of triangular frames 6 and has a through hole for inserting a handle. The handle allows the pay-off shaft 4 to be rotated.

[0033] Multiple anti-reverse blocks 13 are evenly installed on the lower surface of the front crossbar 1, preferably two. The anti-reverse blocks 13 can prevent the support body from moving when the cable reel is empty, and at the same time facilitate the workers to lift the front crossbar 1 of the support body to remove and install the cable reel, making the cable reel operation faster and easier.

[0034] A tension adjustment assembly is installed on one side of the pay-off shaft 4 and the main body of the support to adjust the rotational speed of the pay-off shaft 4 and ensure pay-off stability. The tension adjustment assembly includes a linkage gear a2 and a linkage gear b7. The linkage gear a2 is mounted on the mounting plate 17 and rotates with the pay-off shaft 4. A mounting base 11 is fixedly installed on the side wall of the top of the triangular frame 6 near the mounting plate 17. A fixed shaft is fixedly installed on the mounting base 11, and the linkage gear b7 is rotatably mounted on the fixed shaft 11. The linkage gear b7 meshes with the linkage gear a2. The thickness of the linkage gear a2 is much greater than the thickness of the linkage gear b7, and the diameter of the linkage gear b7 is much greater than the diameter of the linkage gear a2. A clamping assembly is installed on the outer side of the linkage gear b7 on the fixed shaft 11. The clamping assembly includes a clamping spring 8 and a spring pressure plate 12. Both the clamping spring 8 and the spring pressure plate 12 are sleeved on the fixed shaft. The end of the fixed shaft is threaded with a rotating nut 9. The clamping spring 8 is located between the rotating nut 9 and the spring pressure plate 12. A set of friction plates is installed on the side of the spring pressure plate 12 away from the clamping spring 8. The friction plates abut against the linkage gear b7.

[0035] One end of the compression spring 8 is connected to the spring pressure plate 12, and the other end is connected to the rotating nut 9. The rotating nut 9 is fixedly installed at the end of the fixed shaft. Both the spring pressure plate 12 and the compression spring 8 are sleeved on the fixed shaft fixedly installed on the mounting base 11. The end of the fixed shaft is threadedly connected to the rotating nut 9. The compression spring 8 is located between the rotating nut 9 and the spring pressure plate 12, and both ends of the compression spring 8 abut against the rotating nut 9 and the spring pressure plate 12, respectively. A set of friction plates is installed on the side of the spring pressure plate 12 away from the compression spring 8, and the friction plates abut against the linkage gear b7. By rotating the rotating nut 9, the spring pressure can be adjusted. The change in the spring pressure causes the friction force of the friction plates to change, thereby adjusting the tension and further ensuring the stability of the wire laying operation.

[0036] Example 2

[0037] Based on the technology of Example 1, such as Figure 4-5 As shown, the difference between Embodiment 2 and Embodiment 1 is that the tension adjustment assembly includes a pulley 15 and a pull rope 14. The pulley 15 is fixedly mounted on the mounting plate 17 and rotates together with the mounting plate 17 and the wire feeding shaft 4. The pull rope 14 is a non-elastic rope, with its middle section wound around the pulley 15. One end of the rope is fixedly mounted on the upper surface of the crossbar side wall of the triangular frame 6 near the mounting plate 17, and the other end is fixedly mounted with a return spring 16. The other end of the return spring 16 is fixedly mounted on the lower surface of the crossbar side wall of the triangular frame 6. The rotational speed of the pulley 15 can be limited by the return spring 16 and the pull rope 14, ensuring the stability of the wire feeding operation.

[0038] In Examples 1 and 2, the main body of the support frame is made of 40mm square tubing, which is lightweight, weighing approximately 6kg. Both types of cable trays have been put into actual production in our company and have achieved good results. Example 1, compared to Example 2, exhibits more stable tension and a wider adjustment range; our actual measurements show that the tension range is adjustable from 0 to 7kg.
