Technical Field

[0001] The utility model relates to the technical field of ballastless track construction, in particular to a ballastless track groove template positioning device. Background Art

[0002] Ballastless track refers to a track structure that uses an integral foundation such as concrete and asphalt mixture to replace the granular gravel roadbed. It is also called ballastless track. The main function of the ballastless track limit groove is to buffer the high-speed vibration and impact generated when vehicles pass through the track, protect the roadbed and sleepers, and electrically insulate the signal system.

[0003] After searching, the announcement number is CN218711844U, and the name is a utility model of a plate-type ballastless track limiting groove mold positioning device, which includes a transverse positioning rod and a longitudinal positioning frame fixed at both ends of the transverse positioning rod. Through research and analysis, it is found that although it is only necessary to place the groove mold in the area corresponding to the groove mold positioning frame of the longitudinal positioning frame, which improves the construction progress and accuracy, the following defects still exist to a certain extent.

[0004] For example, it is inconvenient to disassemble the positioning device. Most of the components of the groove module positioning device are connected and fixed by bolts. Therefore, personnel need to use tools to operate one by one during disassembly and assembly, which increases the labor intensity of personnel. The slow installation speed affects the construction efficiency, and the groove template cannot be adjusted up and down, which makes it inconvenient to adjust the depth of the groove. In order to solve the above technical problems, we have designed a ballastless track groove template positioning device. Utility Model Content

[0005] The purpose of the utility model is to provide a ballastless track groove template positioning device, which has the advantages of more convenient and quick disassembly and assembly of the positioning structure, reducing the labor intensity of personnel, improving construction efficiency, and facilitating the adjustment of the groove depth. It solves the problem that the disassembly and assembly of the positioning mechanism is relatively cumbersome, which increases the labor intensity of personnel, affects the construction efficiency, and is inconvenient to adjust the groove depth.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a ballastless track groove template positioning device, including a base, a side template is fixedly connected to the edge of the top of the base, and the front and rear sides of the side template are fixedly connected to fixed plug shells, and the inner cavity of the fixed plug shell is plugged with a supporting mechanism, and the supporting mechanism includes a positioning plug block, and the outer side of the positioning plug block is fixedly connected to a supporting vertical plate, and the top between the front and rear two supporting vertical plates is plugged with a cross beam plate, and the top of the cross beam plate is threadedly connected with an adjusting screw, and the bottom of the adjusting screw is movably connected to a limiting cross plate, and the bottom of the limiting cross plate is connected to the groove template body by bolts.

[0007] Preferably, a limited opening is provided on the surface of the support vertical plate, and a connecting sleeve is welded on the top of the support vertical plate.

[0008] Preferably, the positioning plug includes a plug-in shell, and connecting slides are slidably connected to the left and right sides of the inner cavity of the plug-in shell, a positioning spring is fixedly connected between the left and right connecting slides, and a positioning pin is fixedly connected to the outer side of the connecting slide, and the outer side of the positioning pin passes through the plug-in shell and the fixed plug-in shell in sequence and is chamfered.

[0009] Preferably, plug-in plates are welded to both the front and rear sides of the cross beam plate, and a rotating plate is fixedly connected to the top of the adjusting screw.

[0010] Preferably, connecting vertical plates are welded to both the front and rear sides of the bottom of the limiting horizontal plate, and the surface of the connecting vertical plates is fixedly connected to the groove template body by bolts.

[0011] Preferably, positioning holes are provided on both the left and right sides of the inner cavity of the fixed plug shell, and the front and rear sides of the limiting horizontal plate extend to the inner cavities of the front and rear supporting vertical plates respectively.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. Push the positioning pins on both sides inward to remove them from the positioning sockets, pull the supporting vertical plate outward, and the positioning plug block will be removed from the fixed plug shell. The plug-in board and the limit horizontal plate will be separated from the connecting shell and the limit opening respectively. In this way, the groove module and the positioning device can be disassembled. The disassembly operation is faster and more labor-saving, and it is more convenient to carry.

[0014] 2. According to the depth of the groove, turn the screw forward or reverse to drive the groove template body below to move downward or upward. In this way, the groove template body moves downward to increase the groove depth, and moves upward to reduce the groove depth. This makes the adjustment simpler and more convenient.
