Problems solved by technology

Due to the large number of dial indicators, the reading is time-consuming and laborious, and the filling material perfusion personnel cannot observe the floating and offset of the track plate, and it is difficult to adjust the filling speed in time, resulting in the floating or offset of the track plate exceeding the limit

specific Embodiment

[0032] Such as figure 1 As shown, before pouring, 4 magnetic table bases are placed around the support layer template under the track plate, and each magnetic table base includes 2 universal support arms. Place 8 displacement sensors on the universal support arm respectively, so that 4 are perpendicular to the top surface of the track plate, and 4 are perpendicular to the side of the track plate. Each displacement sensor contact is in contact with the track plate, and the sensor contact is adjusted to keep it in the middle of the sensor range (positive and negative displacements can be detected at this time). Each displacement sensor is connected with the tester host through wires. In the host program of the tester, clear the indications of all displacement sensors to zero.

[0033] During perfusion, as the perfusion volume increases, the track plate rises and shifts, and the main unit of the tester can display it in real time. When the track board floats or the offset is c...

Abstract

The invention discloses an automatic testing and early-warning device for track plate displacement. A formwork is arranged between a track plate and a concrete base. The track plate is provided with a grouting hole and an observation hole. A magnetic gauge stand is fixed to the side face of the formwork, a universal support arm is arranged on the magnetic gauge stand, a displacement detection device is fixed to the end of the universal support arm, a probe of the displacement detection device makes perpendicular contact with the top face and / or the side face of the track plate, and the displacement detection device is connected with a tester host through a connecting wire. The tester host is provided with a recording device, a display device and a printing device, and further provided with an early-warning sound or lamplight prompt device. The automatic testing and early-warning device can automatically detect the floating amount or sinking amount of the track plate during filled layer grouting, is convenient to use, easy to operate and easy and convenient to install, data are accurate and objective, the detection result can be automatically displayed, early-warned, printed and stored, the labor intensity of plate type ballastless track filling layer pouring construction staff is lowered, and efficiency is improved.

Description

technical field [0001] The invention relates to a device for detecting the floating and offset of the track plate during the pouring process of the filling layer of the plate type ballastless track, in particular to an automatic test and early warning device for the track plate displacement. Background technique [0002] The slab ballastless track structure consists of a concrete base, a filling layer under the slab, a track slab, fasteners and rails. The filling layer under the slab is a structural layer poured between the positioned track slab and the concrete base layer or support layer, and its filling material is self-compacting concrete or cement emulsified asphalt mortar (CA mortar), or other new materials. When the filling layer under the slab is poured, due to the flow pressure of the filling material, the pressure of the filling material on the track slab is relatively large, which may easily cause the track slab to float and shift. [0003] In order to ensure a s...
