Grouting device of track board

Abstract

The invention provides a grouting device of a track board. The device comprises a canning car, a storage hopper, a conveying pipe and a grouting hopper, wherein the storage hopper is firmly installed on the canning car by a storage hopper support; a weight sensor is installed on the bottom of the storage hopper; a discharge hole is formed in the lower end of the outer side wall of the storage hopper; the discharge hole is connected to one end of the conveying pipe; the other end of the conveying pipe is connected to a filling head by a flange disk; the filling head is installed at a feeding hole of the grouting hopper; a discharge hole of the grouting hopper is inserted into a grouting hole which is located on the center axis of the track board; the discharge hole of the grouting hopper is in sealed connection with the grouting hole; and the conveying pipe is supported by multiple supporting frames. According to the invention, the structure is simple; grouting effects are good; and manpower cost is greatly saved.

Description

technical field [0001] The invention relates to the technical field of filling, in particular to a track plate grouting device. Background technique [0002] In the existing slab-type ballastless track slab, after the fastening device and the formwork are installed, it is usually necessary to pour self-compacting concrete into the track slab. The existing self-compacting concrete pouring method is to reserve a pouring hole in the middle of the top surface of the track slab. And use a storage hopper and other devices to grout from top to bottom through the pouring hole, wherein the volume of the storage hopper meets the pouring amount of a track plate. [0003] However, the grouting speed will directly affect the molding quality of the slurry in the track plate. Too fast will cause the slurry to be uneven, and too slow will cause the slurry to pre-coagulate and not flow; because the delivery pipe is too long and there is no Supporting function, the slurry in the delivery pip...

Problems solved by technology

[0003] However, the grouting speed will directly affect the molding quality of the slurry in the track plate. Too fast will cause the slurry to be uneven, and too slow will cause the slurry to pre-coagulate and not flow; because the delivery pipe is too long and there is no Supporting function, the slurry in the delivery pipe bends downward due to its own weight, which affects the smoothness of grouting, and even causes the slurry to fail to flow. At present, several staff members are usually required to support the delivery pipe, both time consuming and laborious
