Description

Technical Field

[0001] The utility model mainly relates to the technical field of railway tracks, and in particular to a track frog spacing support plate. Background Art

[0002] According to the relationship between the lane occupation of modern trams and social vehicles, the right of way can be divided into three modes: independent right of way, semi-independent right of way and mixed right of way. Since most of the construction of modern trams in my country is based on the reconstruction of existing roads, they are generally laid on the ground, and the most commonly used right of way is semi-independent right of way and mixed right of way.

[0003] The inventor discovered the following defects during the operation of the specific embodiment:

[0004] In order to achieve the above-mentioned right-of-way form, modern trams mostly use an embedded ballast structure. Due to the inherent structural form of the frog, there is a triangular area at the connection between its heel end and the two rail legs. There is insufficient space in this area. If cement support is used, on the one hand, the support strength is insufficient and it is easy to be crushed, and on the other hand, it is not conducive to the maintenance and maintenance of the frog in the later stage. Patent application number "202021483300.7" discloses a patent application document named "A frog spacing support plate". Through the welding of the patterned plate and the vertical plate, the sliding support plate one and the support plate two are then welded to the vertical plate, and the welded device is inserted into the frog heart of the frog. The support plate one and the support plate two are in close contact with the track. Finally, the connecting plate is fixedly connected to the track by bolts to complete the installation. On the one hand, the gap size between the tracks is guaranteed, and on the other hand, its support strength is increased, safety is improved, and the risk of people stepping on it by mistake is reduced, which is convenient for the later maintenance and maintenance of the track.

[0005] After the support plates 1 and 2 of the above-mentioned mechanism are moved to appropriate positions on the vertical plate, they are welded to the vertical plate, which is not convenient for the later maintenance of the entire device. In addition, the support plates 1 and 2 are directly in close contact with the track, and there is a large friction between the support plates and the track. When the device and the track are installed and maintained in the later stage, the support plates and the sides of the track are easily worn.

[0006] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Utility Model Content

Through the arrangement and coordination of the through holes, the sliders, the slide rails, the protruding blocks, the limit grooves, the thread grooves and the fixing holes, the positioning can be achieved by the bolts after the support plate is moved, which can not only adjust the position of the support plate, but also facilitate the disassembly and assembly of the various components of the later device, and the maintenance is also more convenient.

[0018] The utility model can realize the installation between the support plate and the protection plate through the arrangement and coordination between the connection plate, the connection groove, the protection plate, the jack, the connection frame, the fixing plate, the positioning groove and the spring. The close contact between the protection plate and the side of the track can avoid the direct rigid contact between the track and the support plate, which causes the wear of the device and the track in the later maintenance operation. At the same time, the protection plate can also be disassembled;

[0019] The utility model provides the installation groove so that the installation plate can be welded at different positions of the protection plate, thereby making it selective when connecting with the track, thereby improving the practicability of the device.
