Description

Technical Field

[0001] The present application relates to the technical field of heavy nut disassembly and assembly transportation tools, and in particular to a portable heavy nut disassembly and assembly transportation tool. Background Art

[0002] During the installation of electromechanical equipment, it is often encountered that heavy nuts need to be disassembled, assembled, and transported in places without lifting equipment or in narrow spaces. Due to the heavy weight of heavy nuts, they rely solely on manual disassembly, assembly, and transportation, which is labor-intensive and poses great safety risks. Not only can the heavy nuts be easily damaged and deformed, but they can also easily cause harm to the health of workers. Utility Model Content

[0003] In order to solve or partially solve the problems existing in the related technology, the present application provides a portable heavy nut disassembly and transportation tool, which can disassemble and transport heavy nuts in places where there is no lifting equipment or in narrow space, thereby improving the convenience of the disassembly and transportation process of heavy nuts.

[0004] The present application provides a portable heavy nut disassembly and assembly transportation tool, including a cantilever beam, a cross clip, a cross beam, a hook, a pillar, and a movable wheel. The hook is fixedly installed at the end of the cantilever beam, and the cantilever beam is fixedly connected to the cross beam through the cross clip. Pillars are provided at both ends of the cross beam, and movable wheels are installed at the bottom of the pillars.

[0005] Optionally, in some embodiments, the hook is welded to the end of the cantilever beam, and the heavy nuts can be directly transported through the hook, or a nut clamp can be installed at the hook to assist the hook in transporting the heavy nuts.

[0006] Optionally, in some embodiments, the nut clamp includes a clip, a bolt, a nut, and a protrusion. The clip has an arc-shaped structure, and the two clips are symmetrically arranged. The bolt passes through the two clips and is threadedly connected to the nut. The clip is also provided with a protrusion, and a rope is fixed on the protrusion, and the protrusion is hung on the hook through the rope.

[0007] Optionally, in some embodiments, the radius of the circular cross-section formed by the two clips is smaller than the radius of the circumscribed circle of the large nut.

[0008] Optionally, in some embodiments, a diagonal brace is installed between the cantilever beam and the pillar.

[0009] The technical solution provided by this application may have the following beneficial effects:

[0010] This application uses the movable wheel as a fulcrum and the lever principle to apply force to the heavy nut, thereby lifting the heavy nut through the hook. This not only reduces labor intensity, but also adjusts the lifting height of the heavy nut accordingly by changing the height of the tail end of the cantilever beam, thereby facilitating the disassembly and assembly of the heavy nut. Moreover, this device can be used in narrow spaces without lifting equipment. Compared with manual disassembly and transportation, it is not only safer but also has higher construction efficiency.

[0011] It should be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following describes embodiments of the present application in more detail with reference to the accompanying drawings. Although the accompanying drawings illustrate embodiments of the present application, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

[0019] It should be understood that although the terms "first", "second", "third", etc. may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0020] In the description of this application, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0021] Unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be interpreted broadly. For example, they may refer to fixed or detachable connections, or integration; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0022] In response to the above problems, the present application provides a portable heavy nut disassembly and transportation tool, so that the device can transport and disassemble heavy nuts in places where there is no lifting equipment or in narrow space, thereby improving the convenience of the heavy nut disassembly and transportation device.

[0023] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0024] See also Figure 1 and Figure 2In this embodiment, the portable heavy nut disassembly and assembly transportation tool includes a cantilever beam 1, a cross buckle 2, a cross beam 3, a hook 4, a pillar 6, and a moving wheel 7. The end of the cantilever beam 1 is fixedly installed with a hook 4 by welding, and the cantilever beam 1 is fixedly connected to the cross beam 3 by the cross buckle 2. The left and right ends of the cross beam 3 are vertically welded with pillars 6. The bottom of the pillar 6 is rotatably installed with a moving wheel 7. The moving wheel 7 can optionally use a roller with a self-locking function, so as to facilitate the stability of the device during use. Furthermore, before using the device, the fulcrum position of the cantilever beam 1 can be changed by the cross buckle 2. The closer the fulcrum position is to the hook 4, the less effort is required when lifting the heavy nut 9, but the lifting height is lower; the farther the fulcrum position is from the hook 4, the more effort is required when lifting the heavy nut 9, but the lifting height is higher. By flexibly adjusting the fulcrum position, different usage needs can be met.

[0025] During disassembly, adjust the height of the tail end of the cantilever beam 1 so that the position of the hook 4 corresponds to the heavy nut 9, remove the heavy nut 9 from the equipment, pass the hook 4 through the heavy nut 9, and hang the heavy nut 9 on the hook 4. By pushing this device, the heavy nut 9 can be transported quickly and conveniently. During installation, first hang the heavy nut 9 to be installed on the hook 4, push this device to move it to the installation position, adjust the height of the tail end of the cantilever beam 1, and align the heavy nut 9 with the installation position for installation. This device can reduce the risk of the heavy nut 9 falling during disassembly and assembly, ensure the integrity of the heavy nut 9, and also prevent workers from being injured by the heavy nut 9 falling.

[0026] Furthermore, since some heavy nuts 9 have a special, elongated shape, when such heavy nuts 9 are hung on the hook 4, they are prone to slipping due to unstable center of gravity. Therefore, the device is also provided with a nut clamp 5 corresponding to such special heavy nuts 9. The nut clamp 5 includes a clip 51, a bolt 52, a nut 53, and a protrusion 54. The clip 51 has an arc-shaped structure and is symmetrically arranged between two clips 51. The two clips 51 are fixed together by bolts and nuts. The bolt 52 passes through the two clips 51 and is threadedly connected to the nut 53. By adjusting the nut 53, the distance between the two clips 51 can be changed to accommodate heavy nuts 9 of different sizes. The clip 51 is also provided with a protrusion 54, wherein the number of protrusions 54 can be increased or decreased according to the requirements of disassembly and assembly of the heavy nut 9, and the protrusions 54 are evenly distributed on the circular cross-section formed by the two clips 51. It should be noted in particular that the radius of the circular cross-section formed by the two clips 51 is smaller than the radius of the circumscribed circle of the heavy nut, so that the nut clamp 5 can press the heavy nut 9 to ensure the stability of the device.

[0027] When in use, the nut clamp 5 is hung on the hook 4 by a rope, with the end of the cantilever beam 1 where the hook 4 is located facing downward, and then the heavy nut 9 to be disassembled and assembled is fixed in the nut clamp 5 accordingly. By utilizing the principle of leverage and taking the moving wheel 7 as the fulcrum, force is applied to the cantilever beam 1 on the other side without a hook, and the heavy nut 9 is disassembled and assembled by adjusting the position of the cantilever beam 1 up and down. When the disassembled heavy nut 9 needs to be transported, the cooperation of the moving wheel 7 makes the device suitable for places without lifting equipment or narrow space, which speeds up the transportation efficiency and improves the practicality of the device.

[0028] See also Figure 3 In this embodiment, the hook 4 is S-shaped and is welded to the curved surface of the end of the cantilever beam 1. Compared to directly fixing a linear hook to the circular end of the cantilever beam 1, fixing the S-shaped hook 4 to the curved surface of the end of the cantilever beam 1 not only simplifies the fixing operation, but also increases the force-bearing area, making the upper limit of the external force that the hook 4 can withstand higher, ensuring that the device can disassemble and assemble some heavy nuts 9 that can be directly passed through the middle of the hook.

[0029] See also Figure 1 On the basis of the above embodiment, a U-shaped diagonal brace 8 is installed between the cantilever beam 1 and the pillar 6, wherein the two ends of the diagonal brace 8 are respectively welded to the two pillars 6, and the middle part of the diagonal brace 8 is welded and fixed to the cantilever beam 1. At this time, the diagonal brace 8, the pillar 6 and the cantilever beam 1 form a supporting assembly, which not only enhances the stability of the device, but also reduces the stress burden of the cross buckle 2, making the device more stress-bearing.

[0030] Specific working process:

[0031] When choosing to directly use the hook 4 to disassemble and assemble the heavy nut 9 according to the size of the heavy nut 9, directly pass the hook 4 through the nut. When the hook 4 cannot meet the requirements of carrying the heavy nut 9, choose to use the nut clamp 5 of the corresponding size, and then put the nut clamp 5 on the heavy nut 9, rotate the nut 53 so that the two clips 51 tighten the heavy nut 9, and then connect the protrusion 54 on the nut clamp 5 to the rope, and then connect the other end of the rope to the hook 4, adjust the position of the cantilever beam 1 up and down from the end of the cantilever beam 1 without the hook, use the lever principle to lift the heavy nut 9, and then use manpower to push the moving wheel 7 to move the device to the desired position, so as to realize convenient disassembly and assembly of the heavy nut 9.
