Abstract
The utility model relates to a weighing sensor for rail weighbridges and belongs to the technical field of weighing sensors. The weighing sensor comprises a base and an elastic body fixedly arranged on the base, wherein, the elastic body is formed by support bodies and a cross beam mounted between the support bodies and integrated therewith, and each support body is provided with two downwardly protruding ends and is supported on the base; blind holes are formed on the cross beam in the positions close to the support bodies; and a left horizontal slot and a right horizontal slot are formed at two ends of the cross beam corresponding to the positions above the blind holes and are in mirror symmetry along the vertical central plane of the elastic body. The weighing sensor has the advantages of simple structure and higher weighing precision, and can solve the problems of the prior rail weighbridge such as complex structure, low weighing precision and inconvenient transformation of an old rail weighbridge.
Description
Technical field
The utility model relates to a kind of LOAD CELLS that is used for track scale, belongs to the technical field of LOAD CELLS.
Technical background
Existing track scale normally need carry out process and remould on existing track, set up the complicated weighing system of a cover, as the special-purpose bridge-type weighing device of a kind of track scale (patent No.: CN02223752.6), the double as sensor be provided with stressed platform with the positive middle part of axisymmetric beam surface upper, described stressed platform is provided with rail; Bottom, described crossbeam two ends installs with track scale cement special sleeper respectively.Its structure of the track scale of said structure is comparatively complicated, and weighing precision is not high, and is cumbersome when the old track weighing apparatus is transformed.
Summary of the invention
It is a kind of simple in structure that the utility model purpose is to provide, and the LOAD CELLS that is used for track scale that weighing precision is higher, it is comparatively complicated to have solved the structure that existing track scale exists, and weighing precision is not high, problem such as cumbersome when the old track weighing apparatus is transformed.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: it comprises base and the elastic body that is fixedly installed on the base, described elastic body protrudes downwards the supporting mass that is bearing on the base by two ends and the crossbeam between the supporting mass constitutes, supporting mass and crossbeam are structure as a whole, the position of the close supporting mass of crossbeam is respectively equipped with blind hole, the crossbeam two ends are respectively equipped with corresponding to the position of blind hole top that left level is cracked and right level is cracked, and described left level is cracked and right level is cracked is the mirror image symmetry with elastomeric vertical central plane.The utility model directly constitutes the rail mounted structure by base and elastic body, can directly substitute on the existing track a certain section to carry out weighing measurement, and need not existing track be reequiped, its structure is comparatively simple, in addition, because the direct alternate track of the utility model and need not intermediate transfer is so the precision of its weighing measurement is higher.During installation, only the track of corresponding length need be cut off, replace with this sensor and get final product.Simultaneously, because the joint gap between novel two ends of this reality and the original track is very little, can be good at playing overload-resistant and shock proof effect.
As preferably, the electrical lead wire that described elastomeric crossbeam lower surface is provided with water joint and is connected with elastic body by water joint, described base is provided with the lead-in wire perforation corresponding to the position of water joint below, base lower surface is provided with the groove of guiding in lead-in wire perforation connection, and described electrical lead wire passes lead-in wire perforation back and draws from the lead-in wire groove.Wherein, the utility model is drawn the lead-in wire of strainometer and can be prevented effectively that electrical lead wire the use is subjected to the wearing and tearing of rail wheel, has guaranteed reliability of the present utility model from the lower surface of base.
As preferably, be connected by screw between described elastic body and the base.
As preferably, described base is provided with some installation through holes.During installation, can install and fix by mounting hole on the base and track pillow.
Therefore, the utlity model has simple in structurely, and weighing precision is than characteristics such as height.
