Description

A power line laying frame Technical Field

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

[0002] In power construction, a power line support frame is a device used to support power lines (such as power cables and conductors), which helps ensure the safety and stability of the lines. Power line support frames are commonly used to support, fix and guide power lines during the construction, renovation or maintenance of power lines.

[0003] In modern power construction cable laying frames, the cable sleeve is fitted around multiple cylindrical poles. When laying the cable, the cable sleeve rotates around the poles as the operator pulls the cable. However, because the sleeve and the poles are movable (i.e., there is inertia), the cable will become loose due to inertia after each pull and rotation. In severe cases, this may cause the cables to become entangled. Summary of the Invention

[0004] (1) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a cable laying frame for power construction. This design aims to solve the problem that in existing technologies, the cable sleeve is fitted around multiple cylindrical poles. When laying the cable, the cable sleeve rotates around the poles as the operator pulls the cable. However, because the sleeve and poles are movable (i.e., inertia exists), the cable becomes loose after each pull and rotation due to inertia, potentially leading to tangling between cables in severe cases.

[0006] (2) Technical solution

[0007] To solve the above-mentioned technical problems, this utility model provides a power construction cable laying frame, including a base frame, guide wheels installed at the four corners of the bottom end of the base frame, a support column fixed at the upper center of the base frame, reinforcing rods fixed on both sides of the support column, stabilizing mechanisms installed on both sides of the base frame, a ring frame fixed at the top of the support column, and fixed frames intersecting at the middle of the ring frame, a sleeve rod fixed at one end of multiple fixed frames, and sleeves sleeved around the periphery of multiple sleeve rods, a limiting anti-winding mechanism installed at the middle of one end of one of the fixed frames, the limiting anti-winding mechanism including a preset groove, the preset groove being opened at the middle of one end of one of the fixed frames, a limiting anti-winding component installed at the middle of the preset groove, the limiting anti-winding component including a guide frame, and a convenient mounting component installed on one side of the guide frame.

[0008] Furthermore, the limiting anti-rolling assembly includes a reset spring, which is fixedly installed inside one side of the preset groove. The end of the reset spring is connected to a guide frame. Guide grooves are provided on both sides inside the preset groove. Inner blocks are fixed on the upper and lower sides of the inner side of the guide frame, and a rotating rod is installed in the middle of the two inner blocks. A guide cylinder is fixed around the rotating rod.

[0009] Furthermore, the guide frame and the guide groove are connected by a movable guide connection.

[0010] Furthermore, the guide frame utilizes a return spring to form an elastic reset connection.

[0011] Furthermore, the casual clothing assembly includes a rotating shaft, which is installed below one side of the guide frame. A connecting rod is connected to one side of the rotating shaft, and one end of the connecting rod is provided with an external thread. A fixing rod is connected to the middle of the end of the connecting rod. A threaded groove is opened in the middle of one of the fixing frames, and a torsion block is connected to the end of the fixing rod.

[0012] Furthermore, the external thread and the threaded groove at one end of the connecting rod form a threaded fixed connection.

[0013] Furthermore, the stabilizing mechanism includes a fixing block, which is disposed on both sides of the base frame. A screw groove is provided in the middle of the fixing block, and a bolt rod is screwed into the middle of the screw groove. An anti-slip pad is connected to the end of the bolt rod.

[0014] Furthermore, a threaded lifting connection is formed between the bolt rod and the threaded groove in the middle of the fixing block.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] Before the operator needs to install the sleeve with the wound cable, the fixed rod can be pulled in advance so that the connecting rod and the guide frame can move backward along the guide groove. When the external thread at one end of the connecting rod moves to the screw groove in the middle of the fixed frame, the operator can rotate the torsion block. Under the connection of the external thread and the screw groove, the position of the guide frame can be indirectly fixed. In this state, the operator can easily put the sleeve around the multiple sleeve rods. After installation, the external thread and screw groove are adjusted in the opposite direction to make the guide frame disengage from the limit. At this time, the return spring connected to the inner end of the guide frame can elastically return to its original position. Thus, the rotating rod and guide cylinder on the inner side of the guide frame can always be in contact with the outermost cable of the sleeve. During the cable laying process, the guide cylinder can always move and keep close to the cable by utilizing the return spring, which not only does not affect the cable laying but also avoids the cable from becoming tangled due to the pulling inertia.

[0018] With this invention, workers can use guide wheels to move the base frame that supports the power construction cable laying frame to the cable laying point in advance. Then, workers can manually operate two bolt rods in sequence. Under the thread guidance of the screw grooves in the middle of each fixing block, the anti-slip pads can be pressed down and adhered to the ground, thereby improving the stability of the entire device.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This specific embodiment is a power construction cable laying frame, the structural schematic diagram of which is shown in Figures 1 to 4. It includes a base frame 1, guide wheels 2 installed at the four corners of the bottom end of the base frame 1, a support column 3 fixedly installed at the upper center of the base frame 1, reinforcing rods 4 fixedly installed on both sides of the support column 3, stabilizing mechanisms 5 installed on both sides of the base frame 1, a ring-shaped frame 6 fixedly installed at the top of the support column 3, and fixing frames 7 intersectingly distributed in the middle of the ring-shaped frame 6. A sleeve rod 8 is fixedly installed above one end of each fixing frame 7, and sleeves 10 are fitted around the periphery of each sleeve rod 8. A limit anti-winding mechanism 9 is installed at the middle of one end of one fixing frame 7. The stabilizing mechanism 5 includes a fixing block 51. The fixing blocks 51 are respectively located on both sides of the base frame 1. The middle of the fixing block 51 is provided with a screw groove 52, and a bolt rod 53 is screwed into the middle of the screw groove 52. The end of the bolt rod 53 is connected to an anti-slip pad 54. The bolt rod 53 and the screw groove 52 in the middle of the fixing block 51 form a threaded lifting connection. The staff can use the guide wheel 2 to move the base frame 1, which is used to support the power construction cable laying frame, to the cable laying point in advance. Then, the staff manually moves the two bolt rods 53 in turn. Under the threaded guidance of the screw groove 52 in the middle of each fixing block 51, the anti-slip pad 54 can be pressed down and adhered to the ground, thereby improving the stability of the entire device.

[0027] The limiting anti-winding mechanism 9 includes a preset groove 91, which is located at the middle of one end of one of the fixed frames 7. A limiting anti-winding component 92 is installed in the middle of the preset groove 91. The limiting anti-winding component 92 includes a return spring 921, which is fixedly installed inside one side of the preset groove 91. A guide frame 922 is connected to the end of the return spring 921. The guide frame 922 forms an elastic return connection with the return spring 921. Guide grooves 923 are provided on both sides inside the preset groove 91. Inner blocks 924 are fixed on the upper and lower sides of the inner side of the guide frame 922. A rotating rod 925 is installed in the middle of block 924. A guide cylinder 926 is fixed around the rotating rod 925. The guide frame 922 and the guide groove 923 are connected by a movable guide connection. A portable assembly 93 is installed on one side of the guide frame 922. The portable assembly 93 includes a rotating shaft 931, which is installed below one side of the guide frame 922. A connecting rod 932 is connected to one side of the rotating shaft 931. One end of the connecting rod 932 is provided with an external thread 933 around its periphery. A fixing rod 934 is connected to the middle of the end of the connecting rod 932. A threaded groove 934 is opened in the middle of one of the fixing frames 7. 35. A toggle block 936 is connected to the end of the fixing rod 934. The external thread 933 on one end of the connecting rod 932 forms a threaded connection with the screw groove 935. Before the operator puts on the sleeve 10 with the cable wound, the fixing rod 934 can be pulled in advance so that the connecting rod 932 and the guide frame 922 can be guided backward along the guide groove 923. When the external thread 933 on one end of the connecting rod 932 moves to the screw groove 935 in the middle of the fixing frame 7, the operator can rotate the toggle block 936. Under the connection of the external thread 933 and the screw groove 935, the position of the guide frame 922 can be indirectly fixed. In this state, a single person can easily place the sleeve 10 around the multiple sleeve rods 8. After installation, reverse the external thread 933 and the screw groove 935 to disengage the guide frame 922 from the limit position. At this moment, the return spring 921 connected to the inner end of the guide frame 922 can elastically return to its original position. Thus, the rotating rod 925 and the guide tube 926 provided on the inner side of the guide frame 922 can always be in contact with the outermost cable of the sleeve 10. During the cable laying process, the guide tube 926 can always move and stay close to the cable by utilizing the return spring 921, which not only does not affect the cable laying but also avoids the cable from becoming tangled and twisted due to the pulling inertia.

[0028] Working principle: Workers can use guide wheels 2 to move the base frame 1, which supports the power construction cable laying frame, to the cable laying point in advance. Then, workers manually operate two bolt rods 53 sequentially. Guided by the threads of the screw grooves 52 in the middle of their respective fixing blocks 51, the anti-slip pads 54 are pressed down and pressed against the ground, thereby improving the stability of the entire device. Next, before installing the sleeve 10 with the wound cable, workers can pull the fixing rod 934 to guide the connecting rod 932 and the guide frame 922 backward along the guide groove 923. When the external thread 933 at one end of the connecting rod 932 moves to the screw groove 935 in the middle of the fixing frame 7, workers can rotate the torsion block 936. With the external thread 933 and the screw groove 935 connected, the position of the guide frame 922 can be indirectly fixed. In this state, a single person can easily put the sleeve 10 around the multiple sleeve rods 8. After installation, the external thread 933 and the screw groove 935 are adjusted in the opposite direction to make the guide frame 922 disengage from the limit. At this time, the return spring 921 connected to the inner end of the guide frame 922 can elastically return. Thus, the rotating rod 925 and the guide tube 926 provided on the inner side of the guide frame 922 can always be in contact with the outermost cable of the sleeve 10. During the cable laying process, the guide tube 926 can always move and stick to the cable by the return spring 921, which does not affect the cable laying and also avoids the cable from becoming tangled due to the pulling inertia.

[0029] All technical features in this embodiment can be freely combined according to actual needs.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
