Problems solved by technology

If the above-mentioned traditional clamping device is still used to match the track welding equipment, not only the problem of insufficient opening appears, but also because it is only suitable for clamping the track from one direction, when welding the track on the other side, the welding equipment must turn around The problem of reversing, and the turning and reversing of welding equipment is time-consuming, laborious and troublesome

Embodiment 1

[0023] The basic structure of the asymmetric rail positioning and clamping device in this embodiment is as follows: figure 1 As shown, it includes left and right clamp boxes 2, 3 whose middle parts are hinged to each other through a fixed central hinge shaft 1. The lower parts of the left and right clamping boxes 2 and 3 respectively have relatively convex symmetrical left and right jaws 2-1 and 3-1. The upper ends of the left and right clamp boxes 2 and 3 are respectively hinged with the two ends of the horizontally telescopic clamping oil cylinder 4 . The central hinge shaft 1 is fitted with the hoisting shaft sleeve 6 (the key 5 is mounted on the lower other end of the shaft sleeve main body of the hoisting shaft sleeve 6) which is constrained in the circumferential direction by the key 5 and extends upwards out of the vertical guide block 6-1. The hoisting axle sleeve 6 is contained in the central hinge shaft 1 and is positioned between the left and right clamp casings. ...

Abstract

The invention relates to a positioning clamping device for nonsymmetrical rails and belongs to the technical field of traffic facility construction. The positioning clamping device comprises a left clamp box body and a right clamp box body, which are hinged with each other through a central hinged shaft, wherein the lower parts of the left and right clamp box bodies are respectively provided with symmetric left and right jaws, the upper ends of the left and right clamp box bodies are respectively hinged with the two ends of a clamping oil cylinder, a hoisting shaft sleeve is sleeved on the central hinged shaft, a guide block is mounted at the vertical guide block position, the two sides of the guide block are respectively hinged with the upper ends of symmetric left and right pull rods, the lower ends of the left and right pull rods are respectively hinged with the inner sides of the left and right clamp box bodies, the lower part of the hoisting shaft sleeve extends out of a positioning surface, and the positioning surface is provided with parts contacted with the groove tops at the two sides of the groove type rails; and the bulge shapes of the left and right jaws are at least locally matched with the shapes of the narrow opening sides of upright ribs of the groove type rails respectively. When the positioning clamping device is matched with rail welding equipment, the welding of the nonsymmetrical left and right groove type rails is finished without reversing and changing direction, the labor intensity is greatly relieved, and the operation efficiency is improved.

Description

technical field [0001] The invention relates to a clamping device, in particular to an asymmetric rail positioning clamping device, which belongs to the technical field of traffic facility construction. Background technique [0002] The clamping device is an indispensable positioning device for orbital welding. The typical structure of the track positioning clamping device in the prior art is disclosed by the Chinese patent application number 98106266.0. This type of device suitable for clamping the symmetrical section I-shaped rail includes two pincer clamping devices in the form of double-arm rods, and the assembly On a common mandrel, the two are insulated from each other and can move relatively along the mandrel by connecting their two top hydraulic cylinders. One end of each double arm is hinged on the piston rod of the clamping hydraulic cylinder, and the other end is It is equipped with clamping long claws and conductive claws. A hydraulic multiplier is installed in...
