Description

Technical Field

[0001] The utility model relates to the technical field of rail scale equipment, in particular to an assembled rail scale plate. Background Technique

[0002] At present, the rail scale scheme mainly involves pouring the rail scale equipment on the integral roadbed, with a length of about 58 meters. The length of the rail scale weighing body is about 8 meters. There are two forms of weighing bodies: beam type and beamless type.

[0003] The beam type weighing body is composed of a steel structure. The main equipment in the middle is a steel beam about 3 meters long and column type pressure sensors. On both sides are 3 steel sleepers respectively, which are connected into one body through the steel structure to form an 8-meter-long steel structure beam type weighing body. During installation, it is pushed into place with a jack and traveling wheels, and after fine adjustment, it is fixed on the integral roadbed by pouring concrete.

[0004] The beamless type weighing body is composed of special A-type sleepers and plate type pressure sensors. The A-type sleepers are of two types: steel sleepers and concrete sleepers, which are provided with embedded pipes and steel plates for installing the pipelines of the plate type pressure sensors and fixing the plate type pressure sensors. During installation, it is fixed on the integral roadbed by pouring concrete after fine adjustment.

[0005] The common point of the two schemes is to pour the integral roadbed. Ensure that the vehicle is in a straight state when passing through the weighing body, so as to facilitate weighing the weight of the weighing body and obtain accurate weight data.

[0006] According to the current operation situation, due to long-term heavy vehicle rolling on the integral roadbed, the integral roadbed cracks, the line foundation oozes mud, resulting in the settlement of the integral roadbed, the track geometric dimensions exceeding the limit, affecting the train operation safety, and the rail scale cannot work. According to the strength growth characteristics of concrete, curing time is required. The specification requires curing at normal temperature for 28 days, and the strength reaches 100% of the design strength before it can be used. The construction of the integral roadbed requires blocking the line, and together with the concrete curing time, according to the specification, the line needs to be blocked for at least more than 40 days. If it is for renovation, the reinforced concrete integral roadbed needs to be chiseled and a new reinforced concrete integral roadbed needs to be poured, and the time required for blocking often reaches more than 60 days.

[0007] The places where the rail scale is installed are basically on the shunting routes for entering and leaving the special lines or goods lines, and most of them are the only routes. If the construction is blocked according to the specification, the goods line or special line must be out of service for a long time. In this way, it has a great impact on freight transportation and enterprise production, resulting in huge economic losses. According to the operation characteristics of the special line and goods line, vehicles enter and leave every day. If construction is required, more than 4 hours of blocking construction time can be adjusted, but it cannot be blocked all day long, otherwise it will affect production.

[0008] Existing railway track scales are integrally cast on railway lines. Due to the long-term rolling of truck loads, the foundation sinks, causing mud pumping and resulting in the failure of the track scale. It is necessary to chisel it all out again, which is costly. Currently, track scales in the form of integral ballast beds have the disadvantages of difficult maintenance, high renovation costs, and long construction times. Summary of the Invention

[0052] In this embodiment, the overall of the two types of plates, namely the prefabricated track slab 1 and the prefabricated beamless track weighing body slab 2, both adopt the precast slab method. When making the precast slab, first nail a hollow model with wooden boards, distribute steel bars in the hollow part of the model, then fill the hollow part with cement, and after it dries, knock off the wooden boards, and the remaining is the precast slab.

The thicknesses of both prefabricated plates are preferably 500 mm.

[0054] The assembly method of the entire track scale is as Figure 1 , Figure 6 , Figure 6 , Figure 10 shown. According to this prefabricated scheme, the two prefabricated plate sections of the prefabricated track plate 1 and the prefabricated beamless track scale body plate 2 are laid on the subgrade. A fine crushed stone base layer about 20 cm thick is laid under the prefabricated plate, or a water-stable material can also be laid to ensure the precise leveling of the prefabricated plate. It is only necessary to ensure smooth drainage on both sides. If, after long-term operation, the subgrade changes, the prefabricated plate at the corresponding position can be separately removed for subgrade material replacement, and the line can be blocked for about 4 hours for treatment. The later maintenance cost and the line blocking time are greatly reduced. There is no need to chisel reinforced concrete, and there is no need to consider the concrete setting time.

[0055] This device fully considers the difficulty of maintenance and renovation.

These embodiments are not intended to limit the patent scope of the present utility model. Any equivalent implementation or modification without departing from the present utility model shall be included in the patent scope of this case.
