Abstract

A round pin assembly for preventing loosening is characterized in that a round pin is movably connected with a gasket, and a bolt penetrates through the gasket and is in threaded connection with the round pin. The utility model does not need rivet equipment, and the assembling tool is only a spanner; the round pin component has the anti-loosening function; the working efficiency is improved, and the economic benefit is improved.

Description

Locking round pin subassembly that takes off

Technical Field

The utility model belongs to the technical field of the railway intermodal and relates to locking round pin subassembly that takes off.

Background

At the lever joint of the brake transmission device of the railway vehicle in China, the structural connection form of pull-off or short-tail rivet pin assemblies of various specifications is adopted. Namely, after the rivet pin passes through the connecting piece hole, the gasket is sleeved, finally the lantern ring is penetrated at the end of the rivet pin, and the lantern ring is extruded by a corresponding specification of snap-off or short-tail rivet gun to enable the lantern ring to be plastically deformed to realize anti-drop connection. After the rivet pin is broken and riveted, the rivet pin can only be integrally cut off during replacement; whether the riveting requirement is met or not is judged, the plastic deformation of the lantern ring and the amount of the tail part of the lantern ring exposed at the rivet breaking part need to be detected, and therefore the detection is difficult; the flash and burr at the rivet breaking position need to be polished and removed, and extra workload is increased. After riveting the short tail rivet pulling pin, the short tail rivet pulling pin is either integrally cut off or a special lantern ring breaking and dismounting device is adopted during replacement; whether the riveting requirement is met or not is judged, the plastic deformation of the lantern ring needs to be detected, and whether the three salient points on the lantern ring have obvious extrusion traces or not is judged, so that the riveting device is difficult to detect. The working pressure requirements of the stretch-breaking and short-tail stretch-riveting guns of various specifications are different, a plurality of stretch-breaking and short-tail hydraulic stations are required to be equipped, and the maintenance workload of the stretch-riveting guns and the hydraulic stations is increased. The large-size hand riveter has large mass and is inconvenient to operate in the limited structural space of the vehicle.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an adopt the spanner alright equipment, can judge easily that the equipment requires and from taking locking pine function, save the expense, produce economic benefits's locking round pin subassembly that takes off.

The utility model discloses mainly include round pin, packing ring and bolt.

Wherein, round pin and packing ring swing joint, the bolt passes the packing ring, with round pin threaded connection.

Preferably, the upper end surface of the round pin is provided with a hexagon socket, the lower end surface of the round pin is provided with an internal thread hole, and the outer side of the internal thread hole of the lower end surface is provided with an internal clamping groove from deep to shallow in a clockwise direction.

Preferably, two sets of clamping pieces are arranged outside the inner round hole of the gasket.

Preferably, a set of card forward blanking sets up in the inside round hole outside of packing ring clockwise, and the reverse blanking anticlockwise setting of another set of card is in the inside round hole outside of packing ring, and two sets of cards set up in turn.

Preferably, the end face of the bolt in contact with the washer is provided with an end face inner clamping groove from deep to shallow in the anticlockwise direction.

The utility model discloses in the use, the round pin passes the connecting piece hole with former rivet pin junction of brake adjuster, preceding, back brake lever and pull rod among fixed, the lever of moving about and the well pull rod on domestic railway vehicle bogie and the checking cylinder device, twists clockwise the internal thread hole of round pin tip after wearing the packing ring with the bolt, inserts the interior hexagonal hole of round pin up end with interior hexagonal spanner, and the other end is assembled the completion promptly through spanner tightening bolt flattening packing ring.

Compared with the prior art, the utility model has the advantages of as follows:

(1) The rivet pulling equipment is not needed, and the assembling tool is only a wrench;

(2) The round pin component has the anti-loosening function;

(3) The working efficiency is improved, and the economic benefit is improved.

Detailed Description

In the schematic diagram of the present invention shown in fig. 1 to 9, the upper end face of the round pin 1 is provided with an inner hexagonal hole 2, the lower end face of the round pin is provided with an inner threaded hole 3, and the outer side of the inner threaded hole of the lower end face of the round pin is provided with an inner clamping groove 4 from deep to shallow clockwise. The inside round hole outside of packing ring 5 is equipped with two sets of cards 6, and clockwise setting in the inside round hole outside of packing ring is blanked to a set of card forward, and the reverse blanking anticlockwise setting of another set of card is in the inside round hole outside of packing ring, and two sets of cards set up in turn. The end face of the bolt 7 contacting with the washer is provided with an anticlockwise end face inner clamping groove 8 from deep to shallow. The round pin is movably connected with the gasket, and the bolt penetrates through the gasket and is in threaded connection with the internal thread hole in the lower end face of the round pin.
