Embodiment Construction

[0007] like figure 1 As shown in , a manufacturing method of a jack-up sleeper temporary supporter, which replaces the gravel bag; The shape of the base 1 is a cross-shaped or elliptical whole, and the cross-section of the base 1 (after connecting the bottom edges) is trapezoidal. The base 1 is formed by sand casting or steel plate cutting and welding; the bottom length of the base 1 is more than 20 centimeters. A jack 2 is welded in the middle of the base 1, and the bottom of the base 1 and the jack 2 are vertically connected into one; the jack 2 adopts a hydraulic or screw jack, and two oblique arms 3 are arranged symmetrically on both sides of the jacking rod 5 of the jack 2 , the oblique arm 3 and the jacking rod 5 are welded together; the shape of the oblique arm 3 and the jacking rod 5 after being connected is Y-shaped, and the oblique arm 3 is cut with a plate; the upper end of the two oblique arms 3 The center distance is equal to the center width between two sleeper...

Abstract

The invention provides a method for manufacturing a jacking type sleeper temporary support. The jacking type sleeper temporary support is machined by steel and is structurally composed of a base, a lifting jack and oblique arms. The base is a cross-shaped or oval whole, the lifting jack is welded to the middle of the base, the base and the bottom of the lifting jack are connected into a whole, the two oblique arms are symmetrically arranged on the two sides of a jacking rod of the lifting jack, the oblique arms and the jacking rod are connected into a whole, flat boards are arranged at the upper ends of the two oblique arms respectively, and the middle portions of the flat boards and the top ends of the oblique arms are perpendicularly welded and connected into a whole.

Description

technical field [0001] The invention discloses a method for manufacturing a jack-up type sleeper temporary supporter, which belongs to the field of railway overhaul tools. Background technique [0002] The gravel subgrade of the railway needs to be replaced every few years. In order not to affect the traffic requirements of the railway, temporary support is required under the sleeper that has been hollowed out of the gravel during the slag replacement. The usual method is to put the gravel into pockets Inside, a gravel bag is formed after binding the mouth, and then the gravel bag is put under the sleeper to support both ends of the sleeper and meet the requirements of vehicles passing through temporarily. The disadvantages of this method are high labor intensity, slow operation speed and high support cost. Contents of the invention [0003] The purpose of the present invention is to provide a manufacturing method of a jack-up type sleeper temporary supporter to replace t...
