Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to a tool for fastening anchor bolts of iron towers. Background Technology

[0002] In the field of power transmission, towers are crucial supporting structures. The stability of these towers largely depends on the tightness of their anchor bolts. However, in actual maintenance work, existing tightening tools have many shortcomings when dealing with anchor bolts of various sizes. Due to the diverse specifications of tower anchor bolts, existing tools are insufficient for comprehensive compatibility, requiring the preparation of numerous different types of tools, such as pipe wrenches, socket wrenches, and ratchet wrenches. This cumbersome operation increases the labor intensity of workers and reduces work efficiency. Furthermore, some towers may be located in confined spaces, making tightening difficult. When encountering damaged or overtightened anchor bolt threads, existing tools may not provide sufficient torque for tightening. When disassembling some tower anchor bolts is necessary, those exposed to harsh environments for extended periods, such as moisture and corrosion, may become rusted or jammed. Existing tools often lack sufficient torque and effective disassembly methods for these severely corroded bolts, making disassembly extremely difficult, requiring significant manpower and time, and increasing the difficulty and cost of construction. In summary, given the aforementioned problems with existing tower anchor bolt tightening tools, developing a new type of tool that can efficiently, conveniently, and reliably perform tightening and disassembly operations while adapting to various complex working conditions is of great practical significance and urgency for improving the construction and maintenance efficiency of power towers and ensuring the safe and stable operation of the power system. Utility Model Content

[0003] The purpose of this utility model is to provide a tool for fastening anchor bolts of iron towers to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a tool for tightening anchor bolts of iron towers, comprising a torque wrench, a double chain, and meshing gears. A square driver is installed at one end of the torque wrench. There are two meshing gears, and a connecting block is installed between the two meshing gears. The two meshing gears are detachably mounted on the surface of the square driver. The double chain is connected to the two meshing gears. The surface of the meshing gears is provided with tooth threads, and the tooth threads match the double chain.

[0005] Preferably, one end of one of the meshing gears is provided with a square groove, which passes through the connecting block and the other meshing gear.

[0006] Preferably, the size of the square driver matches the size of the square slot.

[0007] Preferably, the double chain is composed of multiple hinged links, and adjacent links are connected by pins.

[0008] Preferably, the torque wrench includes a grip rod, a limiting ring, a torque adjusting rod, and a direction adjusting rod. The torque adjusting rod is movably mounted on the upper end of the grip rod, and the limiting ring is mounted on the surface of the torque adjusting rod on the surface of the grip rod. The square driver is mounted on one end above the torque adjusting rod, and the direction adjusting rod is mounted on the other end above the torque adjusting rod.

[0009] Preferably, one of the chain links is mounted on the end face of the meshing gear by connecting bolts.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This tower anchor bolt tightening tool utilizes a double-gear structure where two gears mesh together. When torque is applied by the torque wrench, the two gears rotate synchronously. Their closely spaced teeth ensure a comprehensive and powerful engagement with the links of the double chain. This tight contact guarantees efficient and uniform torque transmission from the torque wrench to the double chain, minimizing torque loss and fluctuations during transmission.

[0012] 2. This tower anchor bolt fastening tool features a double chain composed of multiple high-strength, wear-resistant hinged links. The links are tightly connected yet offer excellent flexibility and mobility. When the double chain receives torque from the double-meshing gears, the links move in tandem, ensuring even torque distribution along the chain. Because the links can adaptively adjust their position and angle, the double chain can tightly wrap around the bolt, achieving full and close contact with the bolt surface, facilitating the tightening and loosening of various anchor bolt types.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] like Figures 1 to 4 As shown, the tower anchor bolt fastening tool in this embodiment includes a torque wrench 1, a double chain 2, and meshing gears 3. A square actuator 4 is mounted on one end of the torque wrench 1. There are two meshing gears 3, and a connecting block 5 is installed between them. The connecting block 5 connects the two meshing gears 3. The two meshing gears 3 are detachably mounted on the surface of the square actuator 4. The double chain 2 is connected to the two meshing gears 3. The surface of the meshing gears 3 is provided with toothed threads 6, which match the double chain 2. Chain 2 can tightly wrap around the anchor bolt, achieving full and close contact with the bolt surface. By wrapping the double chain 2 around the anchor bolt surface and engaging the double chain 2 with the meshing gear 3, the double chain 2 contacts the anchor bolt surface. Then, a torque wrench 1 drives the square actuator 4 to rotate. The square actuator 4 drives the double chain 2 to tighten the anchor bolt through the two meshing gears 3. The tension and rotational force generated when the meshing gears 3 rotate can be accurately and evenly applied to the anchor bolt through the double chain 2. This uniform force application avoids excessive or insufficient local force on the bolt, ensuring that the force on all parts of the anchor bolt is consistent during the tightening process, thereby achieving effective tightening of the anchor bolt, achieving the required tightness and stability, and providing reliable connection protection for the related structure.

[0021] Specifically, one end of a meshing gear 3 is provided with a square groove 7, which passes through the connecting block 5 and another meshing gear 3, thereby realizing the combined connection of the square driver 4 and the meshing gear 3.

[0022] Furthermore, the square driver 4 is sized to match the square slot 7, so that the square driver 4 will not wobble inside the square slot 7 when it is inserted into it.

[0023] Furthermore, the double chain 2 is made up of multiple chain links 8 hinged together, and adjacent chain links 8 are connected by pins 9. The chain links 8 are tightly connected and have good flexibility and mobility, which makes it easy for the double chain 2 to tightly wrap around the anchor bolt and achieve full and close contact with the bolt surface. This allows the tensile and rotational forces generated by the double chain 2 to be applied to the anchor bolt accurately and evenly, and the surface of the pins 9 is hardened.

[0024] Furthermore, the torque wrench 1 includes a gripping rod 1001, a limiting ring 1002, a torque adjusting rod 1003, and a direction adjusting rod 1004. The torque adjusting rod 1003 is movably mounted on the upper end of the gripping rod 1001. The limiting ring 1002 is mounted on the surface of the torque adjusting rod 1003 on the surface of the gripping rod 1001. A square actuator 4 is mounted on one end above the torque adjusting rod 1003, and the direction adjusting rod 1004 is mounted on the other end above the torque adjusting rod 1003. The torque adjusting rod 1003 can be adjusted to a suitable torque value and locked using the limiting ring 1002. The direction adjusting rod 1004 is used to adjust the direction of torque application. Since the torque wrench 1 is an existing technology, the principle of how to adjust the torque value and the direction of torque application will not be described in detail.

[0025] Furthermore, a chain link 8 is installed on the end face of the meshing gear 3 by connecting bolts 10. By using connecting bolts 10 to connect a chain link 8 and the meshing gear 3, the installation of the double chain 2 and the meshing gear 3 is achieved.

[0026] The usage method of this embodiment is as follows: When the operator needs to tighten the anchor bolts, firstly, the operator needs to adjust the direction adjustment rod 1004 of the torque wrench 1 according to the specifications and tightening requirements of the anchor bolts on site, and at the same time set the required torque value through the limit ring 1002. Next, the operator firmly grasps the grip rod 1001 of the torque wrench 1 with both hands and applies a stable and continuous rotational force in the set direction. The torque generated by the torque wrench 1 is smoothly transmitted to the meshing gear 3 through the square driver 4. The double gear structure rotates synchronously and smoothly, and its teeth tightly and powerfully drive the double chain 2 to move. Due to the ingenious design of the double gear structure, the double chain 2, driven by the teeth, enables the torque to be transmitted efficiently and evenly. The chain links 8 of the double chain 2, with their excellent mobility and flexibility, adaptively and tightly wrap around the anchor bolts. As the torque is continuously applied, the tension and rotational force generated by the double chain 2 act precisely and evenly on the anchor bolts until the preset torque value is reached, thus successfully completing the tightening operation. When an operator needs to disassemble anchor bolts, firstly, the operator must precisely readjust the torque value of torque wrench 1 according to the specifications and model of the bolts to be disassembled, ensuring the torque direction is in the disassembly direction. Next, the operator must firmly grip the handle 1001 of torque wrench 1 and apply rotational force in the disassembly direction. The reverse torque generated by torque wrench 1 is quickly transmitted to the meshing gear 3, causing its double-gear structure to rotate smoothly in the opposite direction. The gear teeth drive the double chain 2. The reverse torque is then transmitted to the double chain 2, whose links 8 stably and effectively receive and transmit the reverse torque. The double chain 2 applies reverse tension and rotational force around the bolt, gradually loosening it until disassembly is successfully completed.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
