CN202156428U - Anti-deformation device for side beam - Google Patents

Abstract

An anti-deformation device for a side beam is characterized by comprising a main hook, an auxiliary hook, a screw rod, a rotating shaft and positioning pins, wherein the auxiliary hook is rotationally connected to two ends of the main hook and positioned through the positioning pins, and the main hook is provided with a threaded hole matched with the screw rod. When the anti-deformation device is used, an upper cover plate of the side beam is hooked by the main hook and the auxiliary hook firstly, the positioning pins are inserted to be used for positioning, then force is applied to the screw rod, and parts such as a vertical plate and the like are welded after an anti-deformation required value is achieved. After welding is completed, the positioning pins are taken down to lead the auxiliary hook to rotate along the rotating shaft, and then the anti-deformation device can be demounted. The anti-deformation device for the side beam changes the traditional production mode of factories so as to be simple in operation, timesaving and laborsaving, and is light to be mounted and demounted quickly and conveniently, so that production efficiency is greatly improved.

Description

Curb girder reversible deformation device

Technical field

The utility model relates to the reversible deformation device in a kind of bogie truck curb girder production.

Background technology

In passenger train was produced, the curb girder that the traditional mode of production bogie truck is used was by cover plate and riser etc. are welded to form up and down.Because when upper cover plate and riser welding, upper cover plate shrinks downwards, is out of shape bigger; Satisfied not designing requirement, for this reason, adopted the method for controlled deformation to be: the elongated technology beam of welding one on upper cover plate earlier; This beam is heavy section bars such as long about 2 meters rectangle square tube or channel-section steel, treat that upper cover plate and riser weld after, regrind and snap mouth; Take off the technology beam, waste time and energy, production efficiency is low.

The utility model content

The purpose of the utility model provides the device of reversible deformation in a kind of curb girder production process, alleviates labor strength, enhances productivity.

For realizing above-mentioned purpose; The utility model provides a kind of curb girder reversible deformation device; It is characterized in that: comprise main hook, auxiliary hook, screw mandrel, rotating shaft and fastening screw, auxiliary hook is rotatably connected on the main hook two ends and through the fastening screw location, has tapped bore on the main hook and cooperate with leading screw.

The utility model catches on the curb girder upper cover plate through main hook and auxiliary hook, inserts the fastening screw location, forces in screw mandrel then, reach the reversible deformation required amount after, parts such as welding riser, postwelding takes off fastening screw, and auxiliary hook is rotated along rotating shaft, can unload the reversible deformation device.The utility model has changed factory's traditional mode of production mode, and is simple to operate, saves time, laborsaving.This device is light, loads onto to unload efficient and conveniently, and production efficiency greatly improves.

Description of drawings

Fig. 1 is the utility model running condition scheme drawing;

Fig. 2 is the cutaway view along A-A line among Fig. 1;

Fig. 3 is the cutaway view along B-B line among Fig. 1.

The specific embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, the utility model comprises main hook 1, auxiliary hook 2, screw mandrel 3, rotating shaft 4 and fastening screw 5, and auxiliary hook is rotatably connected on the main hook two ends and through the fastening screw location, has tapped bore on the main hook and cooperate with leading screw.Earlier main hook, auxiliary hook are caught on the curb girder upper cover plate during use, plug fastening screw, force in after screw mandrel makes the anti-deformation of 3mm, parts such as welding riser, postwelding takes off latch, and auxiliary hook rotates along connecting pin, unloads the reversible deformation device.

Claims (1)

1. curb girder reversible deformation device is characterized in that: comprise main hook, auxiliary hook, screw mandrel, rotating shaft and fastening screw, auxiliary hook is rotatably connected on the main hook two ends and through the fastening screw location, has tapped bore on the main hook and cooperate with leading screw.
