Description

Technical Field

[0001] The utility model relates to an equipment machinery for rail transit, and specifically relates to a device for preventing wheel sliding. Background Art

[0002] For the XHD1 series locomotive wheelsets, during the oil injection and press-fitting process, due to comprehensive factors such as the geometric tolerance of the axle and the oil film of the injected oil, when the wheel is just press-fitted, there is occasionally a situation where the wheel slides slightly towards the center of the wheelset, resulting in press-fitting errors of the wheelset and potential safety hazards during walking. Therefore, it is necessary to study and solve this problem to eliminate future troubles; 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 of the prior art, the utility model provides a device for preventing wheel sliding, which has a simple structure and can effectively prevent wheel sliding.

[0004] To achieve the above purpose, the technical solution of the utility model is that a device for preventing wheel sliding includes a cylindrical pressing head of a wheelset press. An anti-slip component is provided on the cylindrical pressing head. The anti-slip component consists of a fixed seat, a nut, and a pull rod. One end of the fixed seat is provided with a groove for placing the pull rod. One end of the pull rod is provided with a thread and the other end is provided with a hook. The nut is fitted with the thread at one end of the pull rod to fix the pull rod in the groove of the fixed seat.

[0005] The beneficial effect of the utility model is that it has a simple structure, can effectively prevent wheel sliding, eliminate press-fitting errors of the wheelset, ensure the walking safety of the wheelset, fill in the blank, and meet the needs of the market and customers.

[0010] 100 A device for preventing wheel sliding;

[0011] 200 Cylindrical pressing head;

[0012] 1 Anti-slip component, 11 Fixed seat, 111 Groove, 12 Nut, 13 Pull rod, 131 Thread, 132 Hook;

[0013] 300 Wheel, 2 Oil injection holes. Detailed Description of the Preferred Embodiment

[0014] The embodiments of the present utility model will be described below in conjunction with the accompanying drawings. It should be understood that the embodiments described herein are only used to illustrate and explain the present utility model and are not used to limit the present utility model.

[0015] As Figures 1 to 3 shown, the present utility model discloses a wheel anti-sliding device 100, which includes a cylindrical pressing head 200 of a wheel set press. An anti-sliding component 1 is provided on the cylindrical pressing head. The anti-sliding component is composed of a fixed seat 11, a nut 12 and a pull rod 13. A groove 111 for placing the pull rod is provided at one end of the fixed seat. One end of the pull rod is provided with a thread 131 and the other end is provided with a hook 132. The nut is fitted on the thread at one end of the pull rod to fix the pull rod in the groove of the fixed seat.

[0016] When using this device, fix the fixed seat on the cylindrical pressing head, press the wheel tightly against the cylindrical pressing head, manually insert the end of the pull rod with the hook into the wheel ring groove, and place the other end into the groove of the fixed seat, then put the nut on the thread of the pull rod and tighten it. In this way, when injecting oil into the oil injection hole of the wheel, the wheel will not slide, thus ensuring the assembly quality of the wheel set.

[0017] The above is only one of the embodiments of the present utility model and is not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
