Description

Technical Field

[0001] The utility model relates to equipment machinery for rail transportation, in particular to a device for preventing wheels from sliding. Background Art

[0002] When the XHD1 series locomotive wheels are being press-fitted with oil, due to a combination of factors such as the shape and position tolerance of the axle and the oil film, the wheel occasionally slides slightly towards the center of the wheelset just after the wheels are press-fitted. This causes a wheelset press-fit error and poses a safety hazard to driving, so a solution must be studied to prevent future problems. It is reported that there is currently no technology or method to solve this problem. Summary of the invention

[0003] In order to solve the deficiencies in the prior art, the utility model provides a device for preventing wheels from sliding, which has a simple structure and can effectively prevent wheels from sliding.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the utility model is a device for preventing wheel slippage, which includes a cylindrical pressure head of a wheelset press, and an anti-skid component is provided on the cylindrical pressure head, and the anti-skid component is composed of a telescopic oil cylinder, a pull rod and a connecting rod; one end of the telescopic oil cylinder is fixed on the cylindrical pressure head, and the piston rod at the other end is connected to the pull rod, and there are two connecting rods, one end of one connecting rod is fixed on the cylindrical pressure head, and the other end is connected to the extended end of the cylinder piston rod; one end of the other connecting rod is fixed on the cylindrical pressure head, and the other end is connected to the middle part of the pull rod;

[0005] The pull rod head is provided with a draw hook.

[0006] The beneficial effects of the utility model are that it has a simple structure, can effectively prevent wheel sliding, eliminate wheel set press-fitting errors, and ensure the safe travel of the wheelset, thus filling a gap and meeting the needs of the market and customers.

[0011] 100 A device for preventing wheels from sliding;

[0012] 200 cylindrical pressure head;

[0013] 1 anti-skid assembly, 11 telescopic cylinder, 12 pull rod, 13 connecting rod, 131 hook;

[0014] 300 wheels, 2 oil filling holes. DETAILED DESCRIPTION

[0015] The following describes embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0016] like Figures 1 to 3 As shown, the utility model discloses a device 100 for preventing wheel sliding, which comprises a cylindrical pressure head 200 of a wheelset press machine, on which an anti-skid assembly 1 is arranged, and the anti-skid assembly consists of a telescopic oil cylinder 11, a pull rod 12 and a connecting rod 13; one end of the telescopic oil cylinder is fixed on the cylindrical pressure head, and the piston rod at the other end is connected to the pull rod, and there are two connecting rods, one end of one connecting rod is fixed on the cylindrical pressure head, and the other end is connected to the extended end of the cylinder piston rod; one end of the other connecting rod is fixed on the cylindrical pressure head, and the other end is connected to the middle part of the pull rod;

[0017] The pull rod head is provided with a pull hook 131 .

[0018] When using this device, place the wheel close to the cylindrical pressure head and start the telescopic oil cylinder. At this time, its piston rod pushes the connecting rod and the pull rod forward, so that the hook of the pull rod is above the wheel ring groove. Then, the oil cylinder pulls back and presses down to make the hook enter the ring groove and get stuck. In this way, when oil is injected into the wheel oil injection hole, the wheel will not slide, thereby ensuring the assembly quality of the wheelset. After the oil injection is completed, start the oil cylinder and withdraw the hook.

[0019] The above is only one of the embodiments of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
