Description
Technical field
The utility model relates to car load weighing device technical field, particularly relates to that a kind of car load side is high weighs.
Background technology
Along with the raising of rolling stock travelling speed, to dynamic performance, the adhesion hauling ability of rolling stock, propose more and more higher requirement.Axle is heavily the important parameter of locomotive, and whether locomotive respectively takes turns distribution of weight even; Train when moving to bend, locomotive respectively take turns stressed be a large variable.In bend place, outside rail height differs, thus to make on the wheel of both sides stressed also changes thereupon.In such cases, when locomotive operation at top, can to locomotive increase inclination in various degree.Whether this inclination there will be dangerous or great danger; must by detecting the load-bearing variable quantity of each wheel; namely when both sides wheel height difference 100,120,150,180mm time; the parameters such as the heavy and centre of gravity place of the actual weight value of each wheel, axle differentiate, to guarantee the reliability of locomotive operation and maintenance.
Summary of the invention
The utility model, for solving the deficiencies in the prior art, provides a kind of high precision, high-level efficiency, the technical scheme of the low cost car load weighing device that structure is simple, the work that is easy to controls automatically.
Major technique object to be solved in the utility model is the high-precision weighing sensor selecting our unit to produce.The installation of sensor must keep on the same line with railroad track convex shoulder and locomotive wheel, prevents flexible deformation, improves weighing precision.Weighing rail adopts rail section steel plate processing and fabricating, is fastened by bolts loading plate on sensor.When carrying out monolateral rising detection, only need change the weighing rail of differing heights.Adjustment pad is had to be used for adjusting and highly can to guarantee that all wheels correctly experience weight below weighing rail.
Its concrete technical scheme is: portable car load side height weighing device, it is characterized in that comprising the weighing unit being arranged at each wheel place of car load, be arranged at basic platform and the carrying weighing mechanism of wheel rail both sides, described weighing unit is by the LOAD CELLS be electrically connected successively, weighing data integrated box and weighing instrument composition, be installed on bottom LOAD CELLS on basic platform, LOAD CELLS surface is provided with carrying weighing mechanism, described carrying weighing mechanism comprises loading plate on the sensor be connected surperficial with LOAD CELLS, the weighing rail being arranged at loading plate on sensor and the wheel mat be connected with weighing rail.
Portable car load side height weighing device, LOAD CELLS is directly installed on basic platform, and upper end connects upper loading plate and weighing rail, forms a set of Weighing mechanism, realizes weighing with this.It is characterized in that adopting 20mm carbon steel sheet to weld 3 pieces of limited blocks at mesa base, embed railroad track slot, form simple and easy basic platform, basic platform keeps same level, the Weighing mechanism keeping parallelism on basic platform.Whole weighing detection device, by the uniform distribution of locomotive wheel to locomotive weight, is accurately weighed to each wheel.
As preferably, described basic platform comprises the carbon steel landing slab that thickness is 20mm and 4 lower margins be welded in carbon steel sheet, and lower margin is squeezed in the cement flooring of wheel rail, and carbon steel landing slab flushes with ground.
As preferably, between the carbon steel landing slab of wheel rail both sides basic platform, platform web joint is set.
As preferably, LOAD CELLS is double-shear beam sensor.
As preferably, weighing rail and LOAD CELLS are provided with adjustment pad between loading plate.
As preferably, LOAD CELLS is arranged on basic platform with array way.
As preferably, described weighing rail cross section is identical with rail, and weighing rail upper end has additional groove carrying location.
The beneficial effects of the utility model: the utility model structure is simple, be easy to installation and maintenance, weighing unit is directly installed on basic platform, without the need to other mechanisms; Utilize the weighing rail changing differing heights, without other measurement mechanism; Be easy to automatic control, only by the adjustment pad adjustment height below weighing rail, can guarantee that all wheels correctly experience weight; Reliability is high, cost is low, and the cost of device is reduced greatly; Adopt sensor base plate integrated design, without the need to daily servicing, to reduce thus reliability high for the component of a system in addition simultaneously.
