Problems solved by technology

[0004] However, there are some problems if the clearer described in this patent is used to remove the expansion bolt: 1. The outer sleeve of the expansion bolt forms an irregular shape after being squeezed by force, which is difficult to remove and cut off by using the clearer; After the cleaner cuts the expansion bolt, the screw part on the expansion bolt will also be cleaned up and cannot be reused, resulting in a waste of resources; 3. The cleaner needs to use a good cleaning edge, which virtually increases the entire cleaner The cost is not conducive to the promotion and application

Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] like Figure 1-7 , the expansion bolt cleaning device of this embodiment includes a hollow cylindrical sleeve 1, and a push rod 2 connected with its threaded transmission is perforated in the sleeve 1, and the screw rod 2 can be screwed to apply an axial force to the screw rod 13 of the expansion bolt. Thrust, the axial end of the sleeve 1 is installed with a fixed disk 3, and the center of the fixed disk 3 is provided with a first through hole 14 communicating with the sleeve 1, and the ejector rod 2 is movably penetrated in the axial direction. In the sleeve 1 and the first through hole 14 of the fixed disk 3, the fixed disk 3, the sleeve 1 and the push rod 2 are arranged coaxially. In order to facilitate the screwing of the ejector rod 2, the end of the ejector rod 2 is installed with a force rod 11 perpendicular to its axi...

Abstract

The invention relates to the technical field of bolt detaching auxiliary tools, in particular to an expansion bolt cleaner. The expansion bolt cleaner comprises a hollow cylindrical sleeve. An ejector rod with one end capable of exerting axial thrust on a threaded rod of an expansion bolt is arranged in the sleeve in a penetrating mode. A fixed disc is installed at the axial end of the sleeve. The ejector rod is arranged in the sleeve and the fixed disc in the mode that the ejector rod can axially move. The side, away from the sleeve, of the fixed disc is provided with a chuck for fixing the outer sleeve of the expansion bolt. By means of the cleaner, the expansion bolt can be completely removed from an existing fixing point, operation is easy, convenient and rapid, lots of time can be saved, wall or ground near the expansion bolt installation point can not be damaged, no dust or other pollutants can be produced, applied materials are low in price and easy to obtain, and great popularization value is achieved.

Description

technical field [0001] The invention relates to the technical field of bolt removal aids, in particular to an expansion bolt cleaner. Background technique [0002] In the field of industry and life, expansion bolts are a very common part, which can be used to set up force-bearing hanging points in places that are difficult to exert force, and can be used in a wide range of fields. However, in some cases, it is extremely difficult to remove the expansion bolts when they are installed incorrectly. In some cases, the expansion bolts are corroded or need to be repositioned, and the previously installed expansion bolts need to be cleaned up. The common method is to use a sledgehammer to bend the installed expansion bolts and leave them in place or smash them into the ground or wall. In other cases, use an angle grinder to grind the exposed part of the expansion bolt to make it fit with the ground or wall to avoid affecting other components. No matter which method is used, the t...
