Abstract
Description
Technical Field
[0001] The utility model relates to the field of railway track assistance, in particular to a one-way wheel stopper for a locomotive wheel set, which is symmetrically welded to the inner sides of two rails and can limit the one-way passage of the wheel set on a wheel set maintenance line, thereby effectively preventing the wheel set from slipping. Background Art
[0002] During the maintenance process of railway vehicle wheelsets, after the previous maintenance process is completed, the wheelsets need to be transported to the next maintenance link via the wheelset maintenance line. In order to prevent accidents caused by wheelset slippage and ensure the safety and reliability of the wheelset during transportation, operators need to place non-fixed wheel stoppers between the rails and the tread. Non-fixed wheel stoppers have disadvantages such as short life, poor use effect, difficulty in storage, and easy loss during use. The position of the wheel stoppers needs to be moved frequently, and accidents such as wheelset slippage due to forgetting to place the wheel stoppers often occur. Summary of the invention
[0003] In order to solve the problem that the current railway vehicle wheelset maintenance process uses manually placed non-fixed wheel stoppers, the position of the wheel stoppers needs to be frequently moved in actual work, and the non-fixed wheel stoppers are difficult to keep, easy to lose, and easy to damage, etc., the utility model provides a fixed locomotive vehicle wheelset one-way wheel stopper, which is symmetrically welded to the inner side of the rail, can realize one-way passage of the wheelset, and the other side can play an effective anti-slip effect.
[0004] The technical solution adopted by the utility model to solve the technical problem is: a fixed locomotive vehicle wheel pair one-way wheel stopper symmetrically welded to the inner side of a rail, comprising an outer seat, an inner seat, a triangular ratchet plate, a connecting hole arranged on the triangular ratchet plate, a fastener inserted into the connecting hole, and a flat washer between the triangular ratchet plate and the inner seat.
[0005] A further improvement of the technical solution of the utility model is that the welding is carried out on the inner sides of the two rails and the welding is symmetrical on the left and right.
[0006] A further improvement of the technical solution of the utility model is that the fastener is a cylindrical pin.
[0007] A further improvement of the technical solution of the utility model is that the end of the triangular spine plate adopts a circular arc for smooth transition.
[0008] A further improvement of the technical solution of the utility model is that the triangular ratchet can rotate within a range of 0° to 95° in the direction of the feed wheel.
[0009] A further improvement of the technical solution of the utility model is that it can realize the passing of wheels in one direction and effectively prevent slipping in the other direction.
[0010] The beneficial effect of the utility model is that it can be welded and fixed at any required position of the wheelset maintenance line, without the need for human operation, and the work is safe and reliable. It can realize the passage of the wheelset in one direction, and can effectively prevent the wheelset from slipping in the other direction, effectively solving the problem of the operator frequently moving the wheel stopper position. The device can make the wheelset stationary on the rails, and will not slip. It needs to be used in pairs and symmetrically welded to the inner side of the rails. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0012] Figure 1 This is the front view of the utility model;
[0013] Figure 2 It is a side view of the utility model;
[0014] Among them: 1. triangular spine plate, 2. flat washer, 3. cylindrical pin, 4. inner seat, 5. outer seat. DETAILED DESCRIPTION
[0015] The utility model discloses a one-way wheel stopper for a wheel pair of a locomotive and a vehicle, see Figure 1 , Figure 2 It includes an outer seat 5 welded to the inner side of the rail, an inner seat 4 fitted with the outer seat 5, a cylindrical pin 3 placed in the connecting hole of the inner seat 4, the inner seat 4 is placed in the outer seat 5 through a clearance fit, a flat washer 2 passing through the cylindrical pin 3 and in contact with the inner seat 4, and a triangular spine plate 1 passing through the cylindrical pin 3.
[0016] The utility model discloses a one-way wheel stopper for wheelsets of locomotives and vehicles. The device is symmetrically welded to the inner side of the rail at the required position on the wheelset maintenance line, so that the wheelset can pass in one direction and the wheelset can be kept stationary on the rail in the other direction without sliding down the rail, thereby eliminating the corresponding safety hazards and eliminating the need for workers to frequently move the position of the movable wheel stopper. The utility model can be applied to the transportation and maintenance of wheelsets.
[0017] like Figure 1 , Figure 2 As shown, when the triangular ratchet plate 1 is not affected by external force, it is in a vertical position due to its own gravity. When a maintenance wheelset passes through on the right side, the triangular ratchet plate 1 rotates counterclockwise to a horizontal position under the external force of the wheelset. At this time, the wheelset can pass normally until the wheelset passes completely, and then the triangular ratchet plate 1 returns to the vertical position due to its own gravity. At this time, the wheelset on the left cannot pass, thereby realizing the unidirectional passage of the maintenance wheelset and effectively preventing slipping.
[0018] The triangular thorn plate 1, the flat washer 2, the cylindrical pin 3 and the inner seat 4 are separate components and can be quickly removed when not in use.
