Abstract

The invention relates to a track weighing device which comprises a pedestal, two weighing sensors arranged in the pedestal, a test management system communicated with the weighing sensors, guiding blocks arranged on two ends of the pedestal via keys, and a spandrel girder which is arranged on part, positioned between the two guiding blocks, of the pedestal. The spandrel girder is supported on the weighing sensors via rolling columns or rolling beads, and therefore vertical load of the spandrel girder can be measured conveniently. The pedestal has a U-shaped cross section; an inner plate arranged on one side where the pedestal and a railway track are assembled together is smaller than an outer plate arranged on the other side in height, and the outer plate is higher than the spandrel girder. A boss is arranged at the center of the pedestal, the spandrel girder can be supported by the boss when the spandrel girder is overloaded, and two ends of the pedestal and the boss are provided with via holes used for track assembling. Via use of the track weighing device, dynamic, continuous and high precision measurement of a train can be realized; high measuring capability and convenience of installation can be realized, and the track weighing device can be widely applied to railway train weight, overload and unbalance load measurement.

Description

A kind of rail weighing device

Technical field

The present invention relates to a kind of weighing device, particularly to a kind of rail weighing device.

Background technology

It is presently used for the weighing device of railroad train and has the static state railroad track scale weighed and not parking weigh of stopping Dynamic railway truck scale.Static state railroad track scale can be divided into mechanical type, electric-mechanic control system formula and three kinds of forms of electronic type. Wherein, mechanical type static state railroad track scale is made up of bearing platform, lever system and indicating value device, during weighing, Railroad train is accurately parked on bearing platform with the speed less than 3km/h, and after unhook, department scale person moves thick stick In lever system, the large and small sliding weight on measuring lever makes measuring lever balance, by large and small sliding weight leading, Indicating value sum on auxiliary lever reads and weighs.Although mechanical type static state railroad track scale have weighing accuracy high, Stable performance and the advantage such as economical and practical, but but have that operation is complicated, efficiency of weighing is low and should not pacify It is contained in train to come in and go out the first-class shortcoming of circuit frequently.The structural principle of electric-mechanic control system formula static state railroad track scale with Mechanical type is identical, and difference is that measuring lever junction is equipped with a LOAD CELLS and aobvious by weighing Show that device shows weighing automatically.Electric-mechanic control system formula static state railroad track scale because LOAD CELLS application and one Determine to improve in degree efficiency of weighing, but still there is operation complexity and be not advantageously mounted at train discrepancy Shortcoming on circuit frequently.Electronic type static state railroad track scale is by bearing platform, sensor, Weighing display device Table becomes with numeral groups of printers, although electronic type static state railroad track scale has display automatically and weighs numerical value and beat Print the advantages such as record of weighing, information transmission and continuous metering, but but exist and inconvenient and cost is installed The shortcomings such as height.

Dynamic railway truck scale can be divided into broken rail dynamic railway truck scale and unceasing axle type dynamic railway truck scale.At present should With most be broken rail dynamic railway truck scale, it has, and volume is big, it is high to manufacture mounting cost, install week Phase length, inconvenience working service and be inconvenient to measure the shortcoming such as unbalance loading of vehicle when measuring.Rail break is not moved State track scale weighs the track of measurement zone and connects railroad track by fish platee, does not has independent bearing platform, The shortcoming that accordingly, there exist impact shock and the mechanical wear caused when not having car.

Summary of the invention

For above-mentioned technical problem, the present invention provides one to be capable of Train Dynamic continuously, in high precision Measure, the rail weighing device that measurement capability is strong and easy for installation.

For solving above-mentioned technical problem, the technical solution used in the present invention is: a kind of track weighing dress Put, it is characterised in that: it includes a base, and some LOAD CELLSs being arranged in base are described LOAD CELLS connects a test and management system, and two are fastenedly connected drawing at described base two ends upper surface Guide block, the spandrel girder on a described base being installed on described in two between bootstrap block, described spandrel girder props up Support is on described LOAD CELLS.

Described base is U-shaped structure, the height of the inner panel of the side that described base assembles with railroad track Less than the height of the outside plate of corresponding opposite side, the height of described outside plate is more than described weighing beam Highly；A centrally disposed boss of described base, all opens at the two ends of described base and described boss It is provided with the through hole for assembling with described track.

Each described bootstrap block is all fastenedly connected with described base by key and bolt.

Described bootstrap block is symmetrical arranged with the vertical centrage of described base, and each described bootstrap block is The structure tilted, is i.e. gradually inclined upwardly from the end of described base to the middle part of described base.

The bottom face of described base offers some osculums.

Described base is fastenedly connected by the web of the rail of the bolt that is located in described through hole with described track.

Described spandrel girder passes through roller support on described LOAD CELLS.

Due to the fact that the above technical scheme of employing, its technique effect reached is: 1, due to the present invention It is bolted in rail web, it is not necessary to rail break, therefore, in the structure not destroying original track On the basis of can conveniently realize installation and removal, thus have that operating expenses is low and short construction period Etc. advantage.2, it is arranged in the groove protecting wheel base due to the LOAD CELLS of the present invention, and on it It is provided with bootstrap block and load bearing cross beam, therefore, by bootstrap block and the protection of load bearing cross beam, it is possible to have Effect reduces its impact shock of outer bound pair and mechanical wear.3, will gather due to the LOAD CELLS of the present invention The train load signal arrived transmits to test and management system, by the program energy that test and management system is built-in Enough realize vehicle weight by bogie, the statistics in compartment and unbalance loading, overweight etc. monitoring capacity.4、 Owing to protecting of the present invention offers osculum on wheel base, discharged in real time in the present invention by osculum Water, therefore, it is possible to be prevented effectively from water to LOAD CELLS and the impact of whole device, thus improves The service life of the present invention.5, it is more than load-bearing depth of beam due to the height of the outer panel of base of the present invention, Therefore, it is possible to effectively prevent wheel from deviating from from track.

Accompanying drawing explanation

The invention will be further described below in conjunction with the accompanying drawings:

Fig. 1 is the schematic front view of the present invention；

Fig. 2 is the structural representation of the present invention and track installation.

Detailed description of the invention
