Description

Technical Field

[0001] This utility model relates to the field of fuel tank technology, and in particular to an emergency braking locking device for locomotive wheels. Background Technology

[0002] The locomotive wheel emergency braking locking device is a safety device in the locomotive braking system. Through a series of mechanical structures, the device quickly and firmly locks the locomotive wheels, preventing them from rotating, thereby stopping the locomotive in the shortest possible time and effectively avoiding vehicle collisions caused by insufficient braking.

[0003] For example, a composite locomotive braking device disclosed in Chinese Patent Publication No. CN206914351U includes pneumatic brake shoes, a brake cylinder, and an air tank. This composite locomotive braking device also includes an electromagnetic brake block that can simultaneously contact the wheels and the rails on which the locomotive is located. The electromagnetic brake block is provided with a wheel contact part and a rail contact part. A suction part is provided between the wheel contact part and the rail contact part. The suction part corresponds to the suction surface of an electromagnet fixed to the bottom of the locomotive. A top spring is provided between the suction part and the suction surface of the electromagnet. The electromagnet and the solenoid valve that controls the brake cylinder are both connected to the output end of a controller.

[0004] When the brake shoe is in contact with the outer side of the wheel brake ring, friction occurs between the brake shoe and the brake ring, which generates heat and produces corresponding debris. The debris gradually accumulates on the contact surface between the brake shoe and the brake ring, affecting the tightness of the fit between them. This reduces the efficiency of brake force transmission, significantly diminishes the braking effect, and significantly extends the braking distance of the locomotive. In emergency braking, the locomotive may not be able to stop in time, leading to serious safety accidents. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art where friction occurs between the brake shoes and brake rings, generating heat and producing corresponding debris. This debris gradually accumulates on the contact surface between the brake shoes and brake rings, affecting the tightness of their fit and reducing the efficiency of brake force transmission. Therefore, this invention proposes an emergency braking locking device for locomotive wheels.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an emergency braking locking device for locomotive wheels, comprising a mounting plate, a brake arc frame symmetrically and movably connected to one side of the mounting plate, an arc-shaped brake shoe fixedly installed on the inner side of the two brake arc frames, a plurality of chip discharge grooves opened on one side of the arc-shaped brake shoe, a movable circular hole opened at the center of the mounting plate, a wheel axle movably passing through the interior of the movable circular hole, a brake ring fixedly installed on the outer side of the wheel axle, and the arc-shaped brake shoe disposed on the outer side of the brake ring.

[0007] Preferably, the mounting plate has a positioning rod fixed through it in a centrally symmetrical manner.

[0008] Preferably, the inner side of the brake arc frame is provided with an adjustment groove, and one end of the positioning rod moves through the interior of the adjustment groove.

[0009] Preferably, the interior of the mounting plate has several No. 1 mounting holes arranged in a ring.

[0010] Preferably, a transmission plate is fixedly installed on one side of the brake arc frame.

[0011] Preferably, a positioning groove is provided on one side of the transmission plate, and two mounting holes are symmetrically provided inside the positioning groove. A drive cylinder is provided on one side of the transmission plate, and the drive end of the drive cylinder is fixedly connected to the inside of the positioning groove by bolts.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, two arc-shaped brake brackets are attached to the brake ring, and the arc-shaped brake shoes are attached to the outside of the brake ring, which increases the contact area between the brake shoes and the brake ring, reduces the pressure per unit area, and thus reduces the wear rate. At the same time, when the brake shoes and the brake ring rub against each other and generate debris, the debris enters the interior of the debris discharge groove to achieve the purpose of debris discharge. The heat generated by friction can also be transferred to the external environment through the debris discharge groove, thereby achieving the purpose of heat dissipation and discharge, and improving the tightness of the fit between the arc-shaped brake shoes and the brake ring.

[0014] 2. In this invention, when a braking command is issued, the drive cylinder responds rapidly, generating a powerful thrust that drives the brake arc frame to move smoothly towards the brake ring. During this movement, the positioning rod slides precisely within the adjusting groove. The adjusting groove and the positioning rod work together to strictly constrain the movement trajectory of the brake arc frame, effectively preventing any deviation during its movement.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides an emergency braking locking device for locomotive wheels, including a mounting plate 1. A brake arc frame 2 is symmetrically and movably connected to one side of the mounting plate 1. Arc-shaped brake shoes 3 are fixedly installed on the inner side of the two brake arc frames 2. Several chip discharge grooves 31 are opened on one side of the arc-shaped brake shoes 3. A movable circular hole 11 is opened at the center of the mounting plate 1. A wheel axle 4 is movably passed through the interior of the movable circular hole 11. A brake ring 41 is fixedly installed on the outer side of the wheel axle 4. The arc-shaped brake shoes 3 are located on the outer side of the brake ring 41. Several No. 1 mounting holes 13 are opened in a ring arrangement inside the mounting plate 1.

[0023] The specific setup and function of this embodiment are described below. Bolts are passed through several mounting holes 13 in sequence, and mounting plate 1 is installed on one side of the frame. Wheel axle 4 passes through movable circular hole 11. Then, brake ring 41 and brake arc bracket 2 are installed in sequence. When emergency braking is required, the two brake arc brackets 2 are attached to brake ring 41, and arc brake shoe 3 is attached to the outside of brake ring 41, increasing the contact area between brake shoe and brake ring 41 and reducing the pressure per unit area, thereby reducing the wear rate. At the same time, when brake shoe and brake ring rub against each other and generate debris, the debris enters the inside of chip discharge groove 31 to achieve the purpose of chip removal. The heat generated by friction can also be transferred to the external environment through chip discharge groove 31, thereby achieving the purpose of heat dissipation and discharge, and improving the tightness of the fit between arc brake shoe 3 and brake ring 41.

[0024] Example 2: Figure 1 - Figure 4As shown, the locomotive wheel emergency braking locking device of this utility model includes a mounting plate 1. A brake arc frame 2 is symmetrically and movably connected to one side of the mounting plate 1. Arc brake shoes 3 are fixedly installed on the inner side of the two brake arc frames 2. Several chip discharge grooves 31 are opened on one side of the arc brake shoes 3. A movable circular hole 11 is opened at the center of the mounting plate 1. A wheel axle 4 is movably passed through the interior of the movable circular hole 11. A brake ring 41 is fixedly installed on the outer side of the wheel axle 4. The arc brake shoes 3 are located on the outer side of the brake ring 41. A positioning rod 12 is fixedly and symmetrically passed through the interior of the mounting plate 1. An adjustment groove 21 is opened on the inner side of the brake arc frame 2. One end of the positioning rod 12 is movably passed through the interior of the adjustment groove 21. A transmission plate 5 is fixedly installed on one side of the brake arc frame 2. A positioning groove 51 is opened on one side of the transmission plate 5. A second mounting hole 52 is symmetrically opened inside the positioning groove 51. A drive cylinder is provided on one side of the transmission plate 5. The drive end of the drive cylinder is fixedly connected to the interior of the positioning groove 51 by bolts.

[0025] The overall effect of this embodiment is that the drive cylinder, located on one side of the transmission plate 5, plays a crucial driving role in the locomotive braking system. When a braking command is issued, the drive cylinder responds rapidly, generating a powerful thrust that drives the brake arc frame 2 to move smoothly towards the brake ring 41. During this movement, the positioning rod 12 slides precisely within the adjusting groove 21. The adjusting groove 21 and the positioning rod 12 work together to strictly constrain the movement trajectory of the brake arc frame 2, effectively preventing any deviation during its movement. This ensures that the arc-shaped brake shoe 3 mounted on the brake arc frame 2 fits precisely against the outside of the wheel axle 4, thereby greatly improving the braking effect and ensuring the stability and reliability of the locomotive braking process.

[0026] The usage and working principle of this device are as follows: Bolts are passed through several mounting holes 13 in sequence, mounting plate 1 is installed on one side of the frame, wheel axle 4 is passed through movable round hole 11, and then brake ring 41 and brake arc bracket 2 are installed in sequence. When emergency braking is required, the two brake arc brackets 2 are attached to the brake ring 41, and the arc brake shoe 3 is attached to the outside of the brake ring 41, increasing the contact area between the brake shoe and the brake ring 41 and reducing the pressure per unit area, thereby reducing the wear rate. At the same time, when the brake shoe and brake ring rub against each other and generate debris, the debris enters the interior of the debris discharge groove 31 to achieve the purpose of debris discharge. The heat generated by friction can also be transferred to the external environment through the debris discharge groove 31, thereby achieving the purpose of heat dissipation and discharge.

[0027] The drive cylinder, located on one side of the transmission plate 5, plays a crucial driving role in the locomotive braking system. When a braking command is issued, the drive cylinder responds rapidly, generating a powerful thrust that drives the brake arc frame 2 to move smoothly towards the brake ring 41. During this movement, the positioning rod 12 slides precisely within the adjusting groove 21. The adjusting groove 21 and the positioning rod 12 work together to strictly constrain the movement trajectory of the brake arc frame 2.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
