Disc rail slider type split nested single side bolt fastener installation tool

Abstract

The invention relates to a circular disc guide rail slide block type mounting tool for a split nested type one-sided bolt fastener. The mounting tool comprises a bolt operating rod, gasket supporting rods, spring slide blocks, a housing and a rotary assembly, wherein the housing and the rotary assembly are separately arranged on the bolt operating rod up and down in a sleeving mode; the top surface of the housing is provided with first slide slots in a radial direction; second slide slots which form included angles with the first slide slots are arranged in the rotary assembly; the tops of the spring slide blocks are placed into the first slide slots; the bottoms of the spring slide blocks are placed into the second slide slots; under an initial state, the spring slide blocks are positioned at the inner ends of the first slide slots and the second slide slots; the rotary assembly is rotated, so that the spring slide blocks are in telescopic movement in the radial direction; and the gasket supporting rods are connected to the spring slide blocks. Compared with the prior art, the mounting tool realizes quick mounting of the one-sided bolt fastener, further can be used for dismounting according to the needs, can be repeatedly used, and has the advantages of being relatively small in size, convenient to carry, relatively convenient and quick to mount, and the like.

Description

technical field [0001] The invention relates to the technical fields of civil engineering and mechanical assembly, in particular to a disc guide slider type split nested unilateral bolt fastener installation tool. Background technique [0002] At present, in the field of civil construction and mechanical installation, there is a large demand for the installation of structural connection and fastening. As far as the currently commonly used bolts are concerned, when connecting and tightening components, workers need to work on both sides of the component at the same time, that is, insert bolts with nuts on one side, and then use tools to tighten the nuts on the other side. . This connection and fastening method is simple in structure, convenient in operation, and good in load bearing, but it is only suitable for open-section members. , it is impossible to use this common bolt-and-nut connection and tightening method. For example: in the steel tube structure and the concrete...
