Anti-seepage internal gluing device for rail fastener detection

Abstract

The invention discloses an anti-seepage internal gluing device for rail fastener detection. A bracket is in a cuboid frame structure; a cuboid frame is formed by connecting transverse plates and longitudinal plates from the top down; the transverse plates are connected with the longitudinal plates through gluing pieces; grooves are formed in the outer walls of the transverse plates and in the outer walls of the longitudinal plates; the gluing pieces are inserted into the grooves of the transverse plates via insertion walls; after the gluing pieces are fit with the surfaces of the transverse plates, the gluing pieces are limited in the grooves; gluing surfaces are used for laying an alpha-cyanoacrylate adhesive layer; the transverse plates are connected with the longitudinal plates through lead screws; the gluing surfaces contain wall surfaces inside and outside the ends of the gluing surfaces; bulges are formed on the wall surfaces outside the ends of the gluing surfaces; and ring-shaped wall surfaces containing an alpha-cyanoacrylate adhesive are arranged between the peripheries of the bulges and the outer walls of the gluing surfaces. The problems that a seepage gap is too large, and the sealing effect and the stability are not good are solved.

Description

technical field [0001] The invention belongs to the technical field of rail fasteners, and in particular relates to an anti-seepage liquid internal bonding device for detection of rail fasteners. Background technique [0002] In the device used for track fastener detection, as an important part of video acquisition, the video acquisition equipment is often hung on the road patrol vehicle, and the line conditions are collected along with the vehicle. The video acquisition equipment is set in the road patrol vehicle, and the specific settings The method is that a frame for positioning the video capture device is provided in the patrol vehicle, and the video capture device also extends out of the bottom of the vehicle body of the patrol vehicle to implement the video capture device. [0003] However, the existing frames are often formed by connecting horizontal plates with top-down vertical plates. In such a connected structure, the section used for connection of the horizontal...

Problems solved by technology

[0003] However, the existing frames are often formed by connecting horizontal plates with top-down vertical plates. In such a connected structure, the section used for connection of the horizontal plate is usually in contact with the side wall of the vertical plate. Screw connection, and then inject α-cyanoacrylate adhesive on the outer wall of the section used to connect to achieve stability and avoid liquid seepage. This type of connected structure requires low tolerance on the surface of the horizontal plate and the longitudinal plate. , especially the cross-sections used to connect horizontal plates. If the cross-sections used to connect are rough, it will make the connected structures unstable and shaken. In addition, the structure of the connected cross-sections is often not simple, especially It is the lower part of the connected structure, and the injection of α-cyanoacrylate adhesive is often done manually according to the shape of the section 11A used for connection, which is not easy to perform due to low efficiency. α-cyanoacrylate adhesive During the injection process, it often happens that the injection is not much and unbalanced. After a certain period of work between the horizontal plate and the top-down vertical plate, the α-cyanoacrylate adhesive will fall off in its components, so that There will be gaps to cause seepage, and the sealing effect is not good
