Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of safety protection equipment, and in particular relates to a device for preventing a brake pin of a diesel locomotive from running out. Background Art
[0002] The brake pin on a diesel locomotive is a crucial component in connecting the main actuators in the air brake system. Due to the nature of locomotive operations in plant areas, frequent braking and braking are required during locomotive operation, which can cause the brake pin's cotter pin to wear, break, and be lost. This can easily lead to the brake pin being ejected during use. This can cause the brake lever on that wheel to fall off and become ineffective, leading to a loss of braking action, increased braking distance, and even the risk of the locomotive being unable to stop. To address this issue, a device has been designed and manufactured to prevent the brake pin from being ejected on diesel locomotives. Utility Model Content
[0003] The purpose of the utility model is to provide a device for preventing the brake pin of a diesel locomotive from running out in response to the above technical problems.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] A device for preventing the brake round pin of a diesel locomotive from running out includes a horizontal lever, a push rod, a vertical lever, a brake shoe clearance adjuster, an elevation adjuster, a suspension rod, a brake shoe support and a brake shoe, wherein the brake shoe is arranged on the brake shoe support, an elevation adjuster is provided on one side of the brake shoe support, a brake shoe clearance adjuster is provided in the middle position of the brake shoe support, a suspension rod is provided in the middle position of the brake shoe clearance adjuster, a vertical lever is provided on one side of the brake shoe clearance adjuster, a push rod is connected to the other end of the vertical lever, and a horizontal lever is provided on the push rod.
[0006] Preferably, the push rod is movably connected to the vertical lever via a first pin, the vertical lever is movably connected to the brake shoe clearance adjuster via a second pin, and the suspension rod is movably connected to the brake shoe clearance adjuster via a third pin.
[0007] Preferably, one end of the pin shaft 1, the pin shaft 2 and the pin shaft 3 is a pin hole, and the other end of the pin shaft 1, the pin shaft 2 and the pin shaft 3 is a gasket.
[0008] Preferably, the gasket is provided with a cotter pin hole.
[0009] The beneficial effects of the utility model are:
[0010] (1) The utility model adjusts the brake shoe by arranging a brake shoe gap adjuster and an elevation adjuster on the brake shoe and the brake shoe support, thereby achieving the braking of the diesel locomotive. The brake shoe gap adjuster pushes the push rod after being applied with a force by a horizontal lever, and the push rod drives the vertical lever to apply force to the brake shoe gap adjuster to adjust the brake shoe support in the horizontal direction. The brake shoe gap adjuster is connected to the locomotive and installed using a suspension rod.
[0011] (2) A gasket is designed and welded on the connection with the round pin to prevent the round pin from running out. It is installed on the other side of the brake pin, which effectively prevents the diesel locomotive brake lever from falling off due to the round pin running out, causing brake failure and locomotive brake loss of control; reduces the labor intensity of maintenance personnel caused by frequent axle pin running out, reduces the number of diesel locomotives shutting down and stopping wheels due to brake failure, and frequently puts them into storage for temporary repairs, effectively improves the transportation efficiency of diesel locomotives, and ensures the safe use of locomotives.

[0015] The present invention will be further described below with reference to the accompanying drawings and working principle:
[0016] like Figure 1 and 2The device shown in the figure prevents the brake pin of a diesel locomotive from running out, including a horizontal lever 1, a push rod 2, a vertical lever 4, a brake shoe gap adjuster 6, an elevation adjuster 8, a hanger 9, a brake shoe support 10 and a brake shoe 11. The brake shoe 11 is arranged on the brake shoe support 10. The brake shoe 11 is used to brake the wheel of the locomotive. The brake shoe support 10 is used to install and fix the brake shoe 11 and adjust the angle of the brake shoe 11 to achieve the effect of braking the locomotive wheel. An elevation adjuster 8 is provided on one side of the brake shoe support 10. When the brake shoe support 10 needs to be adjusted in elevation, the brake shoe support 10 can be adjusted by applying force at one end of the elevation adjuster 8. The adjuster 8 uses its internal function and the spring force elevation angle to adjust the brake shoe support 10. A brake shoe gap adjuster 6 is provided in the middle position of the brake shoe support 10. A suspension rod 9 is provided in the middle position of the brake shoe gap adjuster 6. The brake shoe gap adjuster 6 is connected to the locomotive using the suspension rod 9 for installation. A vertical lever 4 is provided on one side of the brake shoe gap adjuster 6. The other end of the vertical lever 4 is connected to a push rod 2. A horizontal lever 1 is provided on the push rod 2. The brake shoe gap adjuster 6 pushes the push rod 2 after being forced by the horizontal lever 1, and the push rod 2 drives the vertical lever 4 to force the brake shoe gap adjuster 6 to adjust the brake shoe support 10 in the horizontal direction.
[0017] The push rod 2 and the vertical lever 4 are movably connected through the pin shaft 1 3-1, the vertical lever 4 and the brake shoe clearance adjuster 6 are movably connected through the pin shaft 2 3-2, and the suspension rod 9 and the brake shoe clearance adjuster 6 are movably connected through the pin shaft 3-3. One end of the pin shaft 1 3-1, the pin shaft 2 3-2 and the pin shaft 3 3-3 is a pin hole, and the other end of the pin shaft 1 3-1, the pin shaft 2 3-2 and the pin shaft 3 3-3 is a gasket, and an open pin hole is provided on the gasket.
