Through repeated participation in construction, a plurality of construction difficulties exist in practical application: the leveling difficulty of the embedded plate is high, a large number of base plates are needed to level the line during installation, the intervention of the base plates directly influences the installation precision and finally influences the metering precision; the embedded plates are in a top die form, most of the embedded plates generate holes and shrinkage cavities after construction, secondary treatment is caused by unreal embedded plates, and measurement precision is influenced due to poor treatment; all sizes are adjusted manually during mechanical installation, and the difference of the interval sizes of all the positions after the sensor is installed is large or the phenomenon of lateral deviation of a sensor rail bearing groove occurs. The installation time is long, and the influence on the railway safety is caused; the installation process needs the fire and the electrokinetic operation, and the fire and the electrokinetic operation are not allowed in many occasions.

SUMMERY OF THE UTILITY MODEL

In order to solve the adverse factors of long field installation working time, poor buried plate, inadmissible dynamic and electric operation and the like, the utility model provides a quick weighing body construction structure for railway wagon bogie metering.

The technical scheme adopted by the utility model for solving the technical problems is as follows: a quick construction structures of title body for railway freight car bogie measurement, including built-in title platform basis that has hoisting rings and threading pipe, the title platform basis comprises CA mortar layer, concrete foundation layer, buried plate in proper order from bottom to top, and buried plate bottom surface evenly distributed down is setting up the dowel steel with concrete foundation layer rigid coupling together, buried plate top surface both sides respectively the symmetric interval set up a plurality of track sensor bottom plates, every the bottom plate on all fixed being set up track sensor respectively, set up the track backing plate on the track sensor top surface, wherein be close to fixed setting up on the track backing plate of two symmetries of buried plate both sides portion and blocking the anti-creep piece together with the track card, buried plate middle part top surface on set up car number buried plate and car number antenna respectively.

The prefabricated weighing platform plate formed by the construction structure is formed by pouring C60 reinforced concrete at one time, is made of the same material and arranged with the same reinforcing steel bars as the track slab structure of the ballast bed, meets the structural stress requirement and reduces the difference with the track slab. The embedded steel plate is made of Q235 materials and is 40mm thick, an anchor bar structure is welded, anchor bars and an internal reinforcing mesh are welded during manufacturing, a short circuit line and the short circuit line are welded so as to be connected with a grounding electrode during installation, a weighing platform structural member is welded on the prefabricated weighing platform plate before the line is fed so as to form a prefabricated weighing platform structure, the embedded plate is positioned at the bottom of a mold during pouring, and the surface of the embedded plate is derusted to increase the bonding capacity with concrete. The length of the standard track slab of the high-speed railway is 5 meters, and according to the requirements of GB/T11885-2015 automatic track scale, two sides of a weighing platform are respectively provided with an integral track bed which is not less than 25 meters, so that each side is provided with 5 groups of track slabs.

Before installation and implementation, a reinforced concrete structure is manufactured on a line, and maintenance is carried out according to requirements so that the reinforced concrete structure can reach the designed strength. During installation, the prefabricated weighing platform structure and the track slab (for the whole track bed) are arranged on the top surface of the structure according to positioning according to a drawing, steel rails are fixed on the prefabricated weighing platform structure and the track slab, a track professional tool is used for leveling and straightening the line, and a secondary pouring space is reserved between the top surface of the concrete structure and the bottom surfaces of the prefabricated weighing platform structure and the track slab. And (3) pouring the secondary pouring area by using CA mortar, wherein the pouring process refers to the CA mortar construction procedure in the plate-type ballastless track for construction. The vehicle can be debugged by wiring after maintenance, so that the construction utilizes secondary pouring to replace the prior welding form, the construction time is reduced, and fire and electricity are not generated on the site. The buried plate structure manufactured in the form of the bottom die hardly generates shrinkage cavities and bubbles, and the bad phenomenon of buried plate is avoided.

The construction structure is integrally manufactured in a rail weigher manufacturer, and can be put into use by integrally installing and debugging on a railway construction site. The automatic rail weighbridge (ZGU-100-BWL) of the rail pad sensor can meet the technical requirements of GB/T11885-2015 automatic weighbridge, simultaneously reduces the field construction time, meets the construction requirements under the conditions of no fire and no electricity on the field, and simultaneously avoids the inaccurate measurement condition generated by the cavity at the bottom of the buried plate by changing the construction position of the buried plate.
