Technical Field

[0001] The utility model relates to the technical field of railway locomotives, in particular to a special shock absorbing spring for railway locomotives. Background Art

[0002] A railway locomotive mainly includes a locomotive body, a power mechanism installed on the locomotive body, and a roller assembly installed at the bottom of the locomotive body. The roller assembly is located on the rails. Current railway locomotives have problems of bumps and unstable power output during driving.

[0003] During the travel of a railway locomotive, the rollers may sometimes cause the vehicle body to shake, affecting the travel stability of the railway locomotive. Therefore, it is necessary to ensure that the roller assembly is stably driven and has good buffering properties. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a special shock-absorbing spring for railway locomotives.

[0005] The utility model is achieved in this way:

[0006] A special shock-absorbing spring for railway locomotives comprises a pair of mounting plates, a buffer rod is provided on one side of the pair of mounting plates, and a pair of connecting rods are connected between the pair of buffer rods, a pair of bases are installed at the bottom of the buffer rods on one side of the pair of mounting plates, and damping rods are installed at the four corners of the tops of the two pairs of bases, the tops of the damping rods are connected to the buffer plates, buffer mechanisms are provided inside the two pairs of bases, and the buffer mechanisms include moving blocks, fixed plates are installed on both sides of the pair of mounting plates, and a rotating mechanism is provided between the pair of fixed plates, and the rotating mechanism includes a pair of worm gears.

[0007] Furthermore, a motor is installed on an outer side of one of the fixing plates, and a worm is connected between a pair of the fixing plates, and the motor is transmission-connected to the worm.

[0008] The beneficial effect of adopting the above further solution is that, by installing the worm, the worm wheel can be driven to rotate, thereby causing the rotating rod to rotate.

[0009] Furthermore, a pair of rotating rods are inserted between the pair of mounting plates, and a pair of rollers are sleeved on the outside of the pair of rotating rods.

[0010] Furthermore, a fixing block is installed at the top center of the base, and both ends of the pair of rotating rods penetrate the mounting plate and extend to the inside of the fixing block.

[0011] Furthermore, a worm gear is sleeved on the outside of the pair of rotating rods on one side of the roller, and the worm and the pair of worm gears are meshed with each other.

[0012] The beneficial effect of adopting the above further solution is that, by installing a worm gear, the rotating rod can be driven to rotate, so that the roller drives the railway locomotive to travel, thereby improving the stability during travel.

[0013] Furthermore, the buffer rod and the base are both provided with spring grooves, and a slide rod is installed inside the spring groove, and a pair of first springs are sleeved outside the slide rod.

[0014] The beneficial effect of adopting the above further solution is that, by installing the first spring, the front and rear impacts and shaking of the railway locomotive can be prevented, thereby improving the stability during driving.

[0015] Furthermore, a moving block is slidably mounted on the outside of the slide rod, one end of a pair of the first springs are connected to the outside of the moving block, and a second spring is connected between the pair of moving blocks.

[0016] The beneficial effect of adopting the above further solution is that by installing a pair of second springs, the up and down impacts and collisions to which the railway locomotive is subjected can be buffered.

[0017] The beneficial effects of the utility model are as follows: the utility model is a special shock-absorbing spring for railway locomotives obtained by the above design. When the railway locomotive is traveling, the motor is started to drive the worm to rotate. When the worm rotates, it drives a pair of worm wheels to rotate at the same time, so that a pair of rotating rods rotate at the same time, driving the roller to rotate, so that the locomotive travels. When the locomotive encounters uneven ground during travel, the pair of buffer rods will shake up and down, and the damping rod and the second spring will buffer the shaking. At the same time, when the second spring shakes, it is sometimes shaken back and forth. A pair of moving blocks move on the sliding rod, and the movement of the moving blocks can be buffered by the pair of first springs, thereby improving the vibration of the railway locomotive during travel and improving the stability of travel.

[0027] Embodiment 2 of the utility model of a special shock absorbing spring for railway locomotives
