Description

Technical Field

[0001] The present application relates to the technical field of auxiliary tools for disassembling guardrail plates, and in particular to a tool for quickly disassembling and assembling guardrail plate nuts. Background Art

[0002] During the installation and maintenance of highway guardrails, it is essential to remove the connecting bolts and nuts on the guardrails. Figure 4 As shown, the existing guardrail nut includes a guardrail nut screwing portion 32 with a rectangular or hexagonal cross-section, and a guardrail nut end head 32 with a circular cross-section. The diameter of the guardrail nut end head 32 is larger than the maximum diameter of the guardrail nut screwing portion 32.

[0003] Due to the installation standard requirements of the guardrail plate nut, the guardrail plate nut needs to be installed with the cap reversed, that is, the guardrail plate nut end 32 is placed outward. There are other components at the installation position of the guardrail plate nut. When using a wrench to rotate the guardrail plate nut, the handle of the wrench is likely to interfere with other components, making operation inconvenient. If a socket wrench is used, since the diameter of the guardrail plate nut end 32 is larger than the maximum diameter of the guardrail plate nut screwing part 32, an ordinary socket wrench cannot be correctly inserted into the guardrail plate nut screwing part 32.

[0026] Please refer to Figures 1-4 , this application provides a quick disassembling and assembling tool for guardrail nuts, including a sleeve body 1 and a socket part 2; the sleeve body 1 is generally cylindrical, and can also be set as a stepped shaft to reduce the overall mass of the tool, making it more convenient to use, and at the same time conducive to reducing the manufacturing cost of the tool.

[0027] A clamping groove 11 is arranged on the side surface of the lower end of the sleeve body 1, and the lower end of the clamping groove 11 penetrates through the lower end of the sleeve body 1. A relief groove 12 matching the end 31 of the guardrail nut is constructed above the clamping groove 11; a sliding groove 13 is constructed on the side surface of the upper end of the sleeve body 1.

[0028] During use, the clamping groove 11 is used to clamp the screwing part 32 of the guardrail nut, and the end 31 of the guardrail nut is embedded in the relief groove 12. Then, the staff can drive the guardrail nut to rotate by rotating the sleeve body 1. Compared with using a wrench to screw the guardrail nut, the force application position of this application can extend outwards, making the rotation more convenient and conducive to improving the work efficiency of the staff.

[0029] The socket part 2 is sleeved on the sleeve body 1. A protrusion 21 matching the clamping groove 11 is arranged on the inner side surface of the socket part 2. A pull rod 22 extending radially is arranged on the outer side surface of the socket part 2. When disassembling the guardrail plate nut, when the guardrail plate bolt slips, the sleeve body 1 can be pulled outwards through the pull rod 22. Since the end 31 of the guardrail plate nut is larger than its screwing part, the sleeve body 1 will not be separated from the guardrail plate nut, thereby increasing the friction between the guardrail plate bolt and the guardrail plate, and then locking, so that the guardrail plate nut can be rotated smoothly.

[0030] In some specific embodiments, the bottom shape of the clamping groove 11 matches the guardrail plate nut, effectively increasing the contact area between the clamping groove 11 and the screwing part 32 of the guardrail plate nut, reducing the damage of the clamping groove 11 when screwing the guardrail plate nut, and being beneficial to extending the service life of this tool.

[0031] In some specific embodiments, the socket part 2 is annular.

[0032] In some specific embodiments, the socket part 2 is U-shaped. In the normal use state, the socket part 2 can be conveniently detached from the sleeve body to avoid the socket part 2 affecting the rotation of the sleeve.

[0033] In some specific embodiments, the pull rod 22 is a hollow tube. A through hole 14 extending in the radial direction is arranged on the sleeve body 1, and the position of the through hole 14 is matched with the position of the pull rod 22. When rotating the sleeve body 1, a rod can be used to penetrate the through hole 14 and the pull rod 22, thereby locking the position of the socket part 2 on the sleeve body 1. The pull rod 22 can then become a force-increasing rod, making it more convenient for the staff to operate.

[0034] In some specific embodiments, a counterbore 15 with a cross-section matching the connecting rod of the electric wrench is arranged on the upper end surface of the sleeve body 1. When rotating the sleeve body 1, this tool can also be connected to the electric wrench through the counterbore 15, and the sleeve body 1 can be rotated by the electric wrench, making it more convenient to use.

[0035] The embodiments of the present application have been described above. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments. The selection of the terms used herein is intended to best explain the principles of the embodiments, the practical application or the improvement of the technology in the market, or to enable other ordinary technical personnel in the technical field to understand the disclosed embodiments.
