Description

Technical Field

[0001] The utility model belongs to the technical field of track accessories, and in particular relates to a main and auxiliary rail pressure plate. Background Art

[0002] As mentioned in the Chinese patent with application number 201911356613.8: The track of the rail sightseeing train is usually composed of a pair of main rails and a pair of auxiliary rails. The pair of auxiliary rails is arranged between the pair of main rails. Each main rail and each auxiliary rail are respectively fixed to the sleeper by two pressure plates on both sides. The pressure plates are fixed to the sleeper by bolts. The base part is the sleeper. The pressure plates and the sleeper are connected by a bolt group. The main and auxiliary rails are restricted and fixed to the sleeper by the pressure plates. A new type of main and auxiliary rail pressure plate is disclosed. The new type of main and auxiliary rail pressure plate includes a first pressure plate for pressing the outer side of the main rail, a second pressure plate for pressing the inner side of the auxiliary rail, and a pressure plate for being arranged between the main rail and the auxiliary rail. The third pressing plate that presses the inner side of the main rail and the outer side of the secondary rail at the same time, the invention uses the first pressing plate to press the outer side of the main rail, the second pressing plate to press the inner side of the secondary rail, and the third pressing plate arranged between the main rail and the secondary rail to press the inner side of the main rail and the outer side of the secondary rail at the same time. In this way, only one third pressing plate is needed between each main and secondary rail to achieve the functions of the original two pressing plates, so that the main and secondary rail pressing plates are more regular during installation, and the workload and difficulty of installation and debugging are greatly reduced, and the difficulty, cycle and cost of processing and manufacturing of the sleepers are also reduced. The third pressing plate arranged between the main and secondary rails can limit the distance between the main and secondary rails while pressing the main and secondary rails, and the fixing effect is better.

[0003] However, the applicant found that the pressing plate disclosed in the patent still has the following problems during use:

[0004] 1. The specifications need to be customized, otherwise there will be gaps between the two sides of the pressing block and the main rail and the auxiliary rail. After installation, the rail force may be displaced in the left and right directions;

[0005] 2. Leveling is not easy, that is, when the track is not installed horizontally, it is difficult to adjust the level of the main track or the auxiliary track separately. Utility Model Content

[0006] In view of the problems raised by the above background technology, the purpose of the utility model is to provide a main and auxiliary rail pressure plate.

[0007] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0008] A main and auxiliary rail pressure plate, comprising a main body, the main body is T-shaped, a T-shaped slide groove is provided in the middle of the main body, and a through groove connected to the T-shaped slide groove is provided at the bottom of the main body;

[0009] A T-shaped stop block is placed in the T-shaped slide groove, the T-shaped stop block is provided with a column hole, and the main body is provided with a through hole corresponding to the column hole;

[0010] Two sections of top blocks are symmetrically slidably installed in the through slot, and both sections of the top blocks are provided with inclined surfaces;

[0011] The two ends of the main body are provided with placement grooves, and the pressure blocks are placed in the placement grooves. The main body is provided with threaded holes connected to the placement grooves, and the threaded holes are thread-matched and installed with locking screws.

[0012] It is further defined that the through groove is a rectangular through groove, and the corresponding top block is a rectangular top block. With such a design, the inclined surface of the top block will not be offset, thereby ensuring the matching effect with the T-shaped stop block.

[0013] It is further defined that the column hole is a countersunk column hole. Such a design will not protrude from the upper horizontal plane of the main body after the main body is locked, thereby preventing interference.

[0014] It is further defined that the contact end of the T-shaped stop block is provided with a rounded corner. Such a design makes it easier for the top block to be displaced when it comes into contact with the inclined surface.

[0015] It is further defined that the corner position of the main body is arc-shaped. Such a design enhances the load-bearing effect at the corner relative to a right angle.

[0016] The beneficial effects of adopting the utility model are:

[0017] With the structural design of the utility model, when the screw is used to press the T-shaped stopper, the main body will be driven to press downward, thereby achieving the purpose of the main body pressing the auxiliary rail and the main rail. At the same time, during the descent of the T-shaped stopper, the end of the T-shaped stopper will force the top block to move to the left and right sides, thereby resisting the side surfaces of the main rail and the auxiliary rail, thereby preventing the main rail and the auxiliary rail from being displaced in the left and right directions during use;

[0018] By adopting the structural design of the utility model, when the horizontal height of the main rail or the auxiliary rail needs to be adjusted, the locking screw is directly screwed into the screw hole at the corresponding position, so that the end of the locking screw presses against the pressure block, and the main rail or the auxiliary rail of the corresponding position height is adjusted in the height direction by the pressure of the pressure block, thereby achieving the purpose of leveling.

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1 , Figure 2 As shown, a main and auxiliary rail pressure plate of the utility model comprises a main body 1, the main body 1 is T-shaped, a T-shaped slide groove 2 is provided in the middle of the main body 1, and a through groove 3 connected to the T-shaped slide groove 2 is provided at the bottom of the main body 1;

[0026] A T-shaped stopper 4 is placed in the T-shaped slide groove 2, the T-shaped stopper 4 is provided with a column hole 5, and the main body 1 is provided with a through hole 6 corresponding to the column hole 5;

[0027] Two sections of top blocks 7 are symmetrically slidably installed in the through slot 3, and both sections of top blocks 7 are provided with inclined surfaces 8;

[0028] Both ends of the main body 1 are provided with placement grooves 9, and a pressing block 10 is placed in the placement grooves 9. The main body 1 is provided with a threaded hole 11 connected to the placement grooves 9, and a locking screw is installed in the threaded hole 11 to match the thread.

[0029] In this embodiment, when a main rail and auxiliary rail pressure plate is used, after the main rail and auxiliary rail are placed on the sleeper, the main body 1 can be used to cooperate with the T-shaped stopper 4 for pressing and installing. The installation method is that after the screw is screwed into the sleeper through the column hole 5 and the through hole 6, the main rail or the auxiliary rail can be pressed under the effect of the T-shaped structure of the main body 1.

[0030] Furthermore, the top block 7 is placed in the through slot 3. When the T-shaped stop block 4 descends, the end thereof contacts the inclined surface 8, so that the top block 7 is displaced in the left-right direction under the limit of the through slot 3, so that the end of the top block 7 contacts the side surfaces of the main rail and the auxiliary rail, thereby achieving the purpose of contacting the main rail and the auxiliary rail, and preventing the main rail and the auxiliary rail from being displaced in the left-right direction.

[0031] Furthermore, the pressure block 10 is placed in the placement groove 9. When leveling is required, a screw is screwed into the threaded hole 11. It is not difficult for technicians in the relevant field to understand that rotating the screw in the threaded hole 11 can achieve the purpose of pushing the pressure block 10 to move the main rail or the auxiliary rail downward. In this way, the purpose of leveling can be achieved by loosening or tightening the screw at the corresponding position.

[0032] Preferably, the through groove 3 is a rectangular through groove, and the corresponding top block 7 is a rectangular top block. With this design, the inclined surface 8 of the top block 7 will not be offset, ensuring the matching effect with the T-shaped stop block 4. In fact, the shape structure of the through groove 3 can also be considered according to specific circumstances.

[0033] Preferably, the column hole 5 is a countersunk column hole. With this design, after the main body 1 is locked, it will not protrude from the upper horizontal plane of the main body 1 to prevent interference. In fact, the shape and structure of the column hole 5 can also be considered according to specific circumstances.

[0034] Preferably, the contact end of the T-shaped stopper 4 is provided with a rounded corner 12. Such a design makes it easier for the top block 7 to be displaced when it contacts the inclined surface 8. In fact, the size of the rounded corner 12 can also be considered according to specific circumstances.

[0035] Preferably, the corner of the main body 1 is arc-shaped. Such a design enhances the load-bearing effect at the corner compared to a right angle. In fact, measures to enhance the strength of the corner of the main body 1 may also be considered according to specific circumstances.

[0036] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
