Description

Technical Field

[0001] This utility model relates to the field of power transmission line maintenance technology, and in particular to a power transmission line maintenance transmission suspension device. Background Technology

[0002] During the maintenance of power transmission line towers, tools and spare parts need to be frequently passed up and down for use in maintenance work. Since the tools and spare parts vary in size and the towers are usually over 30 meters high, maintenance personnel first carry the transfer rope to a suitable position on the tower during the climbing process. Then, the tools and spare parts to be passed are fixed through the transfer device before being passed. During the transfer process, the hanging point is limited by the rope loop, and the vertical rope is prone to abrasion of the tower material. Increased resistance causes rope damage and safety factors, increases the labor intensity of ground personnel, and increases the number of workers required.

[0003] However, during power line maintenance work while the line is de-energized or energized, the weight of tools, spare parts, and other necessary items carried by personnel on the towers increases exponentially with height, which is not only time-consuming and labor-intensive but also causes rope wear and tear, posing extremely high safety risks. Therefore, a power line maintenance suspension device is provided to solve the problems mentioned in the background section. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a transmission line maintenance transmission suspension device, which aims to improve the existing technology for the transmission line maintenance work when personnel pass tools, spare parts and other necessary items to the towers during power outages and live maintenance. As the height increases, the weight of the transmission increases exponentially, which is not only time-consuming and labor-intensive, but also causes wear and tear on the ropes and poses extremely high safety risks.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a transmission line maintenance transmission suspension device, comprising a main body, a mounting base on the right side of the main body, a fixed base on the lower part of the mounting base, a transmission pulley rotatably connected inside the fixed base, an installation block fixedly connected to the upper part of the fixed base, an installation groove inside the mounting base, fixed plates fixedly connected to both sides inside the mounting base, a pull rod slidably connected inside the fixed plate, a limit plate fixedly connected to the inner side of the pull rod, a spring on the outside of the pull rod, the spring being disposed between the fixed plate and the limit plate, a snap-fit ​​block fixedly installed inside the limit plate, a snap-fit ​​groove inside the installation block, and an installation assembly inside the main body for installing tower materials.

[0006] Furthermore, the mounting assembly includes a fixing bolt, which is disposed on the lower inner side of the main body, and the main body has a U-shaped slot inside.

[0007] Furthermore, a hanging plate limiting pin is provided on the inner middle side of the main body.

[0008] Furthermore, the mounting block is slidably connected inside the mounting groove.

[0009] Furthermore, the locking block is slidably connected inside the locking groove.

[0010] Furthermore, the fixing bolt is threaded inside the main body.

[0011] Furthermore, a hanging ring is fixedly connected to the left side of the main body.

[0012] This utility model has the following beneficial effects:

[0013] In this utility model, when transferring objects during maintenance operations, the operation time and labor intensity are shortened, the wear and damage rate of ropes are reduced, and the work efficiency of operators is improved. It is finely made and highly operable.

[0014] In this invention, by pulling the lever, the locking block and the limiting plate can be compressed by the spring, causing the locking block to disengage from the locking groove of the mounting block. At this point, the transfer pulley on the fixed base can be disassembled and replaced. After replacement, the new transfer pulley is installed into the mounting groove of the mounting base. Then, the lever is released, and the elastic force generated by the spring causes the locking block to re-engage into the locking groove, completing the disassembly and replacement of the transfer pulley.

[0021] 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.

[0022] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a transmission line maintenance transmission suspension device, comprising a main body 1, a mounting base 16 on the right side of the main body 1, a fixed base 7 on the lower part of the mounting base 16, a transmission pulley 2 rotatably connected inside the fixed base 7, an installation block 8 fixedly connected to the upper part of the fixed base 7, an installation groove 9 opened inside the mounting base 16, and the installation block 8 enters the installation groove 9 for preliminary installation, a fixed plate 12 fixedly connected to both sides inside the mounting base 16, a pull rod 10 slidably connected inside the fixed plate 12, a limit plate 15 fixedly connected to the inner side of the pull rod 10, a spring 11 provided outside the pull rod 10, the spring 11 being disposed between the fixed plate 12 and the limit plate 15, a snap-fit ​​block 13 fixedly installed on the inner side of the limit plate 15, a snap-fit ​​groove 14 opened inside the mounting block 8, and an installation assembly provided inside the main body 1 for installing tower materials;

[0023] The transfer pulley 2 is a 1t pulley, which is lightweight and easy to operate. It can flexibly change the angle and position, making it convenient for operators to use. By pulling the pull rod 10, the pull rod 10 drives the locking block 13 and the limiting plate 15 to squeeze the spring 11, so that the locking block 13 is disengaged from the locking groove 14 of the mounting block 8, and the transfer pulley 2 of the fixed seat 7 can be disassembled and replaced. Then, the mounting block 8 of the new transfer pulley 2 is inserted into the mounting groove 9 inside the mounting seat 16. Then, the pull rod 10 is released, and the elastic force of the spring 11 causes the locking block 13 to be locked into the locking groove 14 for limiting and fixing, thereby disassembling and replacing the transfer pulley 2.

[0024] Reference Figure 1 and Figure 2 The mounting components include fixing bolts 6, which are located on the lower inner side of the main body 1. A U-shaped slot 4 is provided inside the main body 1.

[0025] By setting fixing bolts 6, two rows of four-hole fixing bolts 6 are made to fix the bolts to the position of the tower material, to prevent the U-shaped slot 4 from loosening and shifting, and to prevent the equipment from being unstable and causing injury to the workers at the work point. In case of detachment, the equipment will not fall to the ground. The U-shaped slot 4 of the equipment matches the structure, shape and size of the tower material, increasing the stress point and contact surface of the slot, so that the U-shaped slot 4 can be installed in the position of the tower material and locked in the crossarm of the tower.

[0026] Reference Figure 1 , Figure 2 and Figure 4 The main body 1 has a hanging plate limiting pin 3 inside the middle side, the mounting block 8 is slidably connected to the inside of the mounting groove 9, the snap-fit ​​block 13 is slidably connected to the inside of the snap-fit ​​groove 14, the fixing bolt 6 is threadedly connected to the inside of the main body 1, and the left side of the main body 1 is fixedly connected to the hanging ring 5.

[0027] The hanging plate limiting pin 3 can be flexibly adjusted to lock onto the tower material, making operation simple and preventing the overall device from becoming unstable under stress. It is fixed to the device by mutual force with the fixing bolt 6. During maintenance operations, since it is necessary to avoid abrasion of ropes and excessive physical exertion when passing objects on the tower, the transfer pulley 2 can be disassembled and replaced by sliding the mounting block 8 inside the mounting groove 9. The mounting block 8 can be limited and fixed by sliding the locking block 13 inside the locking groove 14. The U-shaped locking groove 4 can be installed on the tower material by the threaded connection of the fixing bolt 6 inside the main body 1. By setting the hanging ring 5, the top ring design is made to meet the needs of on-site operations while ensuring the function of the equipment and taking into account the carrying characteristics.

[0028] Working Principle: When using this device, the operator attaches the hanging ring 5 to their waist, climbs the tower to the appropriate position on the tower material to attach the transfer device, and ensures a secure connection between the hanging ring 5 and the waist attachment point to prevent it from falling. A U-shaped slot 4 is used for installation on the tower material. In actual operation, it is crucial to ensure a reliable and smooth connection between the U-shaped slot 4, the tower material, and the fixing bolts 6; otherwise, inaccurate attachment may occur. The stability of the fixing bolts 6 and the limiting pins 3 during attachment is also important. It is safe and reliable, and ensures smooth connection and disconnection after connection. By pulling the lever 10, the lever 10 drives the locking block 13 and the limiting plate 15 to squeeze the spring 11, so that the locking block 13 is disengaged from the locking groove 14 of the mounting block 8. The transfer pulley 2 of the fixed seat 7 is disassembled and replaced. Then the mounting block 8 of the new transfer pulley 2 is inserted into the mounting groove 9 inside the mounting seat 16. Then the lever 10 is released, and the elastic force of the spring 11 causes the locking block 13 to be locked into the locking groove 14 for limiting and fixing.

[0029] 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. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
