Description

Rubber shock-absorbing device for locomotive suspension

Technical Field

The utility model relates to locomotive shock attenuation technical field, concretely relates to locomotive hangs rubber seismic isolation device.

Background

The inside of a large coke plant needs to transport a train carriage for coal, rails on piers are arranged inside the large coke plant, and the carriage and wheels directly collide and are damaged due to vibration of the carriage in the running process of the rails. Rubber shock blocks are generally added between the carriage and the wheels under protection, but the rubber must be covered with a protective sleeve due to the high temperature and dusty environment of the coke oven. The protective sleeve is metal and cannot be made too large due to space limitations, and if the space is too small, rubber can be placed inside the protective cover when not under pressure. However, when the rubber shock absorber is subjected to pressure, the rubber shock absorber can expand around the upper and lower pressure bearing areas, and if the rubber shock absorber is expanded too much, the rubber shock absorber can tightly abut against the four walls of the protective sleeve, and the shock absorbing effect is lost. The existing damping rubber elastomer is an integral rectangular pad, and because the rubber damper is stressed and then is compressed, deformed and expanded, the expanded part contacts with the four sides of the metal protective cover, so that the rubber damper loses the damping function.

SUMMERY OF THE UTILITY MODEL

To the above defect, the utility model provides a locomotive hangs rubber seismic isolation device receives same power in limited space and makes the compression space expansion range of rubber shock pad all reduce to absorption damping performance has been improved in limited space.

In order to realize the purpose, the following technical scheme is adopted: the locomotive suspension rubber shock-absorbing device comprises a metal shell, a metal cover plate and a shock-absorbing rubber body, wherein the metal shell comprises a groove body and a bottom plate outer edge, the shock-absorbing rubber body is arranged in an inner groove, the cover plate outer edge of the metal cover plate is provided with a pin hole, and the bottom plate outer edge is also provided with a pin hole at a position corresponding to the pin hole on the cover plate outer edge; the rubber body of moving away to avoid possible earthquakes comprises the same rubber monomer of three group structures, and every adjacent two sets of rubber monomers are separated by the metal sheet, and the rubber monomer is pasted by four the same rubber gasket and is formed integratively, and the height that highly is higher than the cell body of the rubber body of moving away to avoid possible earthquakes, and metal covering plate installs on the rubber body of moving away to avoid possible earthquakes' surface, connects metal casing, the rubber body of moving away to avoid possible earthquakes and metal covering plate with the pinhole of long round pin and bolt through apron outer edge and bottom plate outer.

Furthermore, the contact surface of the metal cover plate and the shock-absorbing rubber body is an absolute plane and covers the upper surface of the shock-absorbing rubber body completely.

Furthermore, the shock-absorbing rubber body is higher than the groove body by the thickness of 3-4 rubber gaskets.

Furthermore, a gap is reserved between the shock-absorbing rubber body and the inner wall of the groove body, and the gap distance is not less than 7.5 mm.

Further, the shape of the rubber gasket may be circular or square.

Further, the shape of the metal plate may be circular or square.

The utility model discloses beneficial effect: the structure has a small size of expansion all around after the same force is applied. Thereby improving the absorption and damping performance of the rubber damping pad, reducing abrasion and protecting equipment. The rubber shock pad is attractive in appearance, low in cost and long in service life.

Detailed Description

Examples

The invention is further explained by combining the attached drawings, the locomotive suspension rubber shock absorption device shown in the figure comprises a metal shell (1), a metal cover plate (2) and a shock absorption rubber body (3), wherein the metal shell (2) comprises a groove body (101) and a bottom plate outer edge (102), the shock absorption rubber body (3) is arranged in the built-in groove (101), a pin hole is formed in the cover plate outer edge (201) of the metal cover plate (2), and a pin hole is also formed in the position, corresponding to the pin hole in the cover plate outer edge (201), of the bottom plate outer edge (102). The shock-absorbing rubber body (3) is composed of three groups of rubber monomers with the same structure, every two adjacent groups of rubber monomers are separated by a metal plate (4), and the rubber monomers are adhered into a whole by four same rubber gaskets (301) through strong glue. The shape of the rubber gasket (301) is not limited, and may be circular or square, and the shape of the metal plate (4) may be circular or square. The shock-absorbing rubber body with the structure has small expansion size on the periphery after being subjected to the same force, the longitudinal absorption effect is particularly obvious, more expansion spaces can be obtained in the limited groove body space, namely, more force can be borne in the limited space, and the shock-absorbing effect is excellent. The shock-absorbing rubber body (3) is higher than the groove body (101) by the thickness of 3-4 rubber gaskets (301), a gap is reserved between the shock-absorbing rubber body (3) and the inner wall of the groove body (101), and the distance of the gap is at least 7.5 mm. The shock-absorbing rubber body (3) has enough expansion space when the metal cover plate (2) is stressed to extrude the shock-absorbing rubber body (3), and plays a role in damping. The metal cover plate (2) is arranged on the surface of the shock-absorbing rubber body (3), and the contact surface of the metal cover plate (2) and the shock-absorbing rubber body (3) is an absolute plane and covers the upper surface of the shock-absorbing rubber body (3) comprehensively. And finally, the metal shell (1), the shock-absorbing rubber body (3) and the metal cover plate (2) are connected and fixed into a whole by a long pin (5) and a bolt (6) through pin holes on the outer edge (201) of the cover plate and the outer edge (102) of the bottom plate. When in use, the long pin (5) and the bolt (6) are disassembled and then reassembled and installed on the locomotive.
