Description

Technical Field

[0001] This utility model relates to the field of power transmission line maintenance technology, specifically a portable boom. Background Technology

[0002] Transmission line maintenance mainly involves the tightening of tension points and the inspection and repair of the wires. This results in a very large workload for line maintenance personnel, especially the tightening of tension points of synthetic insulators, which is both labor-intensive and dangerous. It can easily cause cracks in silicone rubber synthetic insulators. In addition, the insulators are corroded by water and vapor during long-term operation, which may cause them to break brittlely and lead to major accidents. During the maintenance of transmission lines, some slings are generally used for assistance.

[0003] Currently, portable hoisting devices commonly used in the power industry are mainly divided into two categories: one is a simple tripod combined with a hand-operated hoist, and the other is a telescopic boom. However, the tripod structure is bulky, inconvenient to transport and erect, and requires a certain amount of working space; while most existing telescopic booms adopt a fixed structure design and have poor stability, easily swaying in high-altitude wind or vibration environments, affecting operational safety. In addition, the locking mechanism of some adjustable booms is complex and cumbersome to operate, which is not conducive to rapid deployment and adjustment. Therefore, we propose a portable boom.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0021] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a portable lifting rod, including a connecting plate 1, a sleeve rod 2, a connecting seat 8, and a load-bearing rod 9. The two ends of the connecting plate 1 are symmetrically connected with sleeve rods 2. The two ends of the connecting plate 1 are symmetrically and integrally provided with adjusting rods 3. The adjusting rods 3 are slidably connected in the sleeve rods 2. The two sleeve rods 2 at the ends of the connecting plate 1 are integrally connected with a connecting rod 7. The top of the connecting rod 7 is provided with a connecting seat 8, and the load-bearing rod 9 is connected inside the connecting seat 8. The end of the load-bearing rod 9 is provided with a hook 10.

[0022] It should be noted that the adjusting rod 3 and the connecting plate 1 are an integral structure, forming an H-shaped structure as the central support structure. Each adjusting rod 3 can be telescopically slidably connected to a sleeve rod 2 on its outer side. The two sleeve rods 2 at each end of the connecting plate 1 are integrally connected by a connecting rod 7, so that the two combined sleeve rods 2 form a U-shaped structure. After the sleeve rods 2 are connected to the connecting plate 1, the overall structure is stable and can ensure the safety of the operators.

[0023] Please see Figure 1 and Figure 3 The adjusting rod 3 has a rectangular cross-section. The sleeve rod 2 is located on the outer side of one end of the connecting plate 1 and is provided with a fastening bolt 5. The top of the adjusting rod 3 is provided with fixing holes 4 at equal intervals, and the end of the fastening bolt 5 is threaded into the fixing hole 4.

[0024] It should be noted that the adjusting rod 3 has a rectangular cross-section and is slidably connected inside the sleeve rod 2. The cavity inside the sleeve rod 2 is rectangular, which makes the connection between the adjusting rod 3 and the sleeve rod 2 stable and prevents the sleeve rod 2 or the adjusting rod 3 from rotating during the adjustment process.

[0025] Please see Figure 1 The bottom end of the load-bearing rod 9 is rotatably connected to the connecting seat 8 via a rotating shaft. The connecting seat 8 has two connecting holes 12 on both sides of the side wall located outside the rotating shaft, and a second fastening bolt 11 is installed in the connecting hole 12. The load-bearing rod 9 has fastening holes on both sides of the side wall, and the end of the second fastening bolt 11 is threaded into the fastening hole.

[0026] It should be noted that the support rod 9 is rotatably installed inside the connecting seat 8. The connecting seat 8 has two connecting holes 12. The second fastening bolt 11 can slide through the connecting holes 12. When the support rod 9 is in a vertical state, the second fastening bolt 11 can be passed through the connecting holes 12 on the upper part of the connecting seat 8, so that it is threaded into the fastening hole on the support rod 9. This makes the support rod 9 and the connecting seat 8 fixedly connected by the two second fastening bolts 11, making the overall structure stable and convenient for supporting the workers.

[0027] Please see Figure 1 The corresponding two side walls of the adjusting rod 3 are provided with sliding grooves, and the corresponding two inner walls of the sleeve rod 2 are integrally provided with limiting sliding rods, which are slidably connected in the sliding grooves of the side walls of the adjusting rod 3.

[0028] It should be noted that during the sliding process of the adjusting rod 3, the limiting slide rod inside the sleeve rod 2 is slidably connected in the slide groove on the side wall of the adjusting rod 3, so that the adjusting rod 3 can always maintain its overall stability and provide better support during the sliding process with the sleeve rod 2.

[0029] Please see Figure 1 Two fixing rods 6 are installed between the bottom of the two sleeve rods 2 at the end of the connecting plate 1.

[0030] It should be noted that, in the initial state of use, the adjusting rods 3 at both ends of the connecting plate 1 are completely inside the four sleeve rods 2, and both load-bearing rods 9 are folded on top of the connecting plate 1. During use, the operator carries the power line maintenance hoist up the tower to the crossarm. The extension / retraction length of the connecting plate 1 and sleeve rods 2 is adjusted according to the distance between the crossarm and the power line to be maintained. During adjustment, the sleeve rods 2 at both ends of the connecting plate 1 are pulled away. After adjustment, the four No. 1 fastening bolts 5 are tightened, and the hook 10 on one end of the load-bearing rod 9 is hooked onto the crossarm. The other end... The hook 10 on the load-bearing rod 9 is attached to the power transmission line. Then, the workers fasten their safety belts and sit on the connecting plate 1 and the sleeve rods 2 at both ends to tighten the tension points and deal with defects on the power transmission line. The connecting plate 1 and the adjusting rod 3 in the rod are an integral structure. The connecting plate 1 and the adjusting rod 3 are an H-shaped structure. The two sleeve rods 2 at one end of the connecting plate 1 are integrally connected by the connecting rod 7. After connection, they form a U-shaped structure. Two fixing rods 6 are fixed between the two sleeve rods 2, making the connection between the connecting plate 1 and the sleeve rods 2 stable and making it safer for the workers to sit on the connecting plate 1 and the sleeve rods 2.

[0031] Please see Figure 3 A handle 13 is provided at the bottom of the connecting plate 1.

[0032] It should be noted that the handle 13 facilitates carrying the boom and adjusting its length.

[0033] Please seeFigure 1 The bottom of the hook 10 is rotatably connected to the top of the support rod 9 via a bearing.

[0034] It should be noted that the bottom end of the hook 10 is rotatably mounted on the support rod 9, which facilitates the adjustment of the hook position of the hook 10, thereby enabling it to better connect with the crossarm and power transmission line.
