Description

Technical Field

[0001] The utility model relates to the technical field of coal mines, in particular to a pneumatically controlled manual heavy-duty tooth-rail movable turnout for mines. Background Technique

[0002] A turnout is a line connection device that enables locomotives and rolling stock to transfer from one track to another, and is usually laid in large quantities at stations and marshalling yards. With turnouts, the passing capacity of the line can be fully utilized. Even on a single-track railway, by laying turnouts and building a turnout track section longer than the train length, trains can run in opposite directions.

[0003] In mine transportation, as an important part of the track line, the performance of turnouts is directly related to the operation efficiency and safety of mine cars. The traditional turnout switching method is mostly manual operation, which is cumbersome and inefficient, and it is difficult to meet the requirements of high-efficiency transportation in modern mines. Therefore, it is of great significance to develop a mine-used turnout with high automation, simple operation and good stability. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages that the traditional turnout switching method is mostly manual operation, which is cumbersome and inefficient, and it is difficult to meet the requirements of high-efficiency transportation in modern mines, and to propose a pneumatically controlled manual heavy-duty tooth-rail movable turnout for mines.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] The pneumatically controlled manual heavy-duty tooth-rail movable turnout for mines includes a main frame assembly. A movable frame assembly is slidably connected to the top of the main frame assembly. On both sides of the bottom of the main frame assembly, a first fixed rail and a third fixed rail are respectively fixedly connected. The first fixed rail and the third fixed rail are symmetrically arranged. On one side of the bottom of the main frame assembly, a second fixed rail is fixedly connected. The second fixed rail is inclined. A straight rail and a curved rail are fixedly connected to the top of the movable frame assembly. The top of the main frame assembly is fixedly connected with a standard cylinder through a connecting component. The output end of the standard cylinder is fixedly connected with the movable frame assembly for switching the curved rail and the straight rail;

[0007] A plurality of reinforcing bars are arranged on the main frame assembly. The reinforcing bars include plate-shaped reinforcing bars and I-shaped reinforcing bars;

[0008] A stabilizing component is arranged on the top of the movable frame assembly and is used to ensure the stability of the movement of the movable frame assembly.

[0009] In a possible design, the connecting component includes a cylinder tail hinge seat fixedly connected to one side of the main frame assembly. The cylinder tail hinge seat is fixedly connected to the main frame assembly by a plurality of fifth hexagon socket head cap screws. One end of the standard cylinder is hinged to one side of the cylinder tail hinge seat. A cylinder hinge head is fixedly connected to the top of the movable frame assembly. The output end of the standard cylinder is hinged to the cylinder hinge head. A first spring washer is fixedly connected to one side of the cylinder tail hinge seat by a fifth hexagon socket head cap screw.

[0010] In a possible design, the stabilizing component includes a plurality of guide wheel connecting seats fixedly connected to the top of the movable frame assembly. A plurality of first traveling wheels and a plurality of second traveling wheels are respectively installed on the tops of the plurality of guide wheel connecting seats. The plurality of second traveling wheels are respectively located on both sides of the plate-shaped reinforcing bar. The plurality of first traveling wheels are respectively located on one side of the two I-shaped reinforcing bars away from each other.

[0011] In a possible design, a second spring washer is provided on one side of each of the plurality of first traveling wheels. The second spring washer is fixedly connected to the movable frame assembly by fourth hexagon socket head cap screws and third hexagon socket head cap screws. A plurality of fourth spring washers are provided on one side of the second traveling wheels. The fourth spring washers are fixedly connected to the movable frame assembly by second hexagon socket head cap screws and hexagon head bolts.

[0012] In a possible design, self-locking cylinder bottom plates are fixedly connected to both sides of the top of the main frame assembly by first hexagon socket head cap screws. A thin cylinder is installed on the top of the self-locking cylinder bottom plate. A self-locking pin is fixedly connected to one side of the main frame assembly. The self-locking pin is used in cooperation with the thin cylinder to limit the position of the movable frame assembly.

[0013] In a possible design, a cylinder housing is fixedly connected to the bottom of the movable frame assembly by a plurality of seventh hexagon socket head cap screws. A pin shaft is arranged inside the cylinder housing. The pin shaft is used to connect the standard cylinder and the cylinder hinge head.

[0015] In a possible design, the first fixed rail, the third fixed rail, and the second fixed rail are all fixedly connected to the main frame assembly by a plurality of sixth hexagon socket head cap screws, third spring washers, and nuts.

[0016] In this application, after the turnout fixed frame is installed and fixed, and the two ends of the tooth rails and flanges are firmly connected to the transportation line track, the switch controls the track-changing drive cylinder to move the movable part of the turnout horizontally within the range of the limit device, so as to realize the docking state between the straight rail and the straight rail or between the straight rail and the curved rail. Then the switch controls the fixed cylinder to move up and down to lock the required track docking state, achieving the docking of the track line required by the user. When it is necessary to switch to another track, the fixed cylinder first releases, and the drive cylinder, with the help of the reversing valve, pushes the walking part of the turnout to move horizontally back to the limit device in place. The fixed cylinder on the other side locks the walking part to realize the docking of the other track, completing the track-changing work and realizing the switching of the transportation line.
