Embodiment Construction

[0033] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0034] like figure 1 and figure 2 As shown, a bevel gear transmission type unilateral bolt fastener installation tool is used to assist in the installation of split nested unilateral bolt fasteners. The split nested unilateral bolt fasteners include sequentially connected high Strength bolts 1, several split gaskets 3, flat gaskets 15 and nuts 16, the installation tool uses bevel gear transmission to realize the radial expansion and closure of split gaskets 3, specifically including bolt support rods 2, pads Sheet support rod 4, slider 7, coil wire 11, bevel gear rotating member 12...

Abstract

The invention relates to a bevel gear drive type unilateral bolt fastener mounting tool. The bevel gear drive type unilateral bolt fastener mounting tool comprises a bolt supporting rod, gasket support rods, sliders, a wire coil, a bevel gear rotating part and a casing, wherein the wire coil is nested in the bolt support rod, the bolt support rod is sleeved with the casing, sliding chutes are formed in the top surface of the casing radially, the bevel gear rotating part is arranged on the casing, a first screw thread is arranged on the top end surface of the wire coil, a bevel gear meshed with the bevel gear rotating part is arranged on the bottom end surface of the wire coil, the tops of the sliders are placed in the sliding chutes, second screw threads meshed with the first screw thread are arranged at the bottoms of the sliders, and the gasket support rods are arranged on the sliders. Compared with the prior art, the mounting tool realizes unilateral mounting, the mounting mode is simple, the processing accuracy requirement is low, and the cost is low, and better economy is realized; meanwhile, reduction of the screw bolt part is not avoided, the bearing load is greatly improved, and the mounting tool has better mechanical property and wide application prospect and can be widely applied to civil construction engineering and the like.

Description

technical field [0001] The invention relates to the technical fields of civil engineering and mechanical assembly, in particular to a bevel gear transmission type unilateral bolt fastener installation tool. Background technique [0002] At present, in the field of civil engineering and mechanical installation, there is a large demand for the installation of connection and fastening of structural parts. As far as bolts are commonly used at present, when performing connection and fastening operations on components, staff need to work on both sides of the components at the same time, and there is still no good implementation method for unilateral installation. This connection and fastening method has simple structure, convenient operation and good load bearing, but it is only suitable for open cross-section components. In some special occasions, such as connecting and fastening closed cross-section components or components that are inconvenient to operate on the other side , i...
