Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary tools for equipment maintenance, and specifically relates to a sleeve-type bolt disassembly and assembly tool. Background Technology

[0002] In the inspection and maintenance of large machinery and electrical equipment, loose or fallen bolts are frequently encountered. Often, the operating space is confined, making it impossible for personnel to pass through or directly reach the required area. Furthermore, components connected by electromechanical bolts are often reinforced with stiffeners at the connection points to increase strength, further confining the bolt installation area. Conventional tools have no room to operate, making it impossible to remove or install bolts independently. The confined space hinders observation, often requiring the removal of surrounding equipment to clear a path, resulting in low efficiency. Sometimes, two people are needed: one to hold the nut in place while the other tightens or loosens the bolt. The confined space makes simultaneous work difficult and hinders coordination. In such situations, tools and parts are prone to falling, further increasing the difficulty.

[0003] Therefore, it is necessary to develop a sleeve-type bolt removal and installation tool to solve the above problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a sleeve-type bolt disassembly and assembly tool.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sleeve-type bolt removal and installation tool includes: a main body, a connecting rod, a sleeve, a nut sleeve, a handwheel, a main body handle, and an n-shaped structure; one end of the main body is provided with a main body handle longitudinally relative to the main body, and the main body handle is fixedly connected to the main body; the other end of the main body is fixedly connected to one end of the n-shaped structure, and the other end of the n-shaped structure is fixedly provided with a nut sleeve; the main body is sleeved outside the connecting rod, and the connecting rod can rotate and extend freely within the main body; one end of the connecting rod is fixedly connected to the sleeve by a pin, and the other end of the connecting rod is fixedly provided with a handwheel.

[0007] Specifically, the handwheel has a keyway in the center, which can be tightened using a 6.3mm ratchet wrench.

[0008] Specifically, the extension range of the connecting rod is 0-29mm.

[0009] The beneficial effects of this utility model are as follows:

[0010] This application, by setting up a main body, connecting rod, sleeve, nut sleeve, handwheel, main body handle, and n-shaped structure, allows one person to operate with both hands simultaneously, while fixing disassembled and assembled bolts and nuts to the tool at the same time, reducing the risk of parts falling off and improving work efficiency and quality.

[0011] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0014] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are 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, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0018] Please see Figure 1 This utility model provides a sleeve-type bolt disassembly and assembly tool, comprising: a main body 1, a connecting rod 2, a sleeve 3, a nut sleeve 4, a handwheel 5, a main body handle 6, and an n-shaped structure 7. One end of the main body 1 is longitudinally provided with the main body handle 6, and the main body handle 6 is fixedly connected to the main body 1; the other end of the main body 1 is fixedly connected to one end of the n-shaped structure 7, and the other end of the n-shaped structure 7 is fixedly provided with the nut sleeve 5; the main body 1 is sleeved outside the connecting rod 2, and the connecting rod 2 can freely rotate and extend within the main body 1; one end of the connecting rod 2 is fixedly connected to the sleeve 3 by a pin, and the other end of the connecting rod is fixedly provided with the handwheel 5.

[0019] Specifically, handwheel 5 has a keyway in the center, which can be tightened using a 6.3mm ratchet wrench.

[0020] Specifically, the extension range of connecting rod 2 is 0-29mm.

[0021] In use, this application utilizes a sleeve 3 that engages with and limits the end of the bolt to be disassembled, and a nut sleeve 4 integrated on the main body 1 that engages with and limits the end of the nut to be disassembled. An n-shaped structure 7 fixedly connected to the main body 1 avoids interference with the equipment structure. During use, the left hand grips the main body handle 6 to keep the main body 1 stationary and limit the nut to be disassembled. The right hand turns the handwheel 5 at one end of the connecting rod 2, and through the force transmitted by the connecting rod 2, the sleeve 3 rotates with the bolt to be disassembled, thus disassembling or assembling the bolt. Simultaneously, the disassembled bolt and nut are held on the tool and removed or transported to the installation location along with the tool. This tool can be operated by one person with both hands simultaneously, reducing the risk of parts falling and improving work efficiency and quality.

[0022] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0023] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
