Description

A kind of buffer brake structure

Technical field

The utility model is related to one kind, particularly a kind of buffer brake structure.

Background technology

Hydraulic bjuffer（shock absorber）Object by hydraulic damping to effect thereon carries out buffer deceleration To stopping, a certain degree of protective effect is played.

Suitable for plant equipment such as lifting transport, elevator, metallurgy, harbour machinery, rail trucks, its effect is worked The safety buffer device for preventing hard collision from causing mechanism to damage in journey.When hydraulic bjuffer is collided pressure, kinetic energy warp Chock plug and acceleration spring are given to piston, move right it.Originally buffer working chamber built with a back-moving spring, push rod with And fluid.Fluid in the motion extruding working chamber of piston, compresses its back-moving spring, at the same make fluid from piston and push rod it Between annular gap squeeze out, into oil storage chamber.In piston setting in motion, due to the annular gap between push rod compared with Greatly, fluid is easily extruded；In when piston continues to move, this annular gap becomes less and less, i.e. piston resistance is continuous Increase, to after the cylindrical stage of push rod, resistance is also stable at maximum.The process that buffer is compressed is by piston press The process of fluid acting.This process consumes a large amount of kinetic energy, plays cushioning effect.When work is finished, piston is reset spring Home position is pushed into, a working cycles are completed.

The content of the invention

Technical problem to be solved in the utility model is to provide a kind of buffer brake structure, releasing of brake structure Complete to reset, recover the state to before clashing into, and simple structure, energy-absorbing scope is big.

In order to realize solving the purpose of above-mentioned technical problem, the utility model employs following technical scheme：

A kind of buffer brake structure, including fixed support, level 2 buffering body, buffering spacer, buffer body fixed cover, front Block, disk spring, conical friction plate, lock shaft are held in plate, backboard, sliding axle, brake tightly；Buffering spacer is arranged on level 2 buffering The front end of body；

Level 2 buffering body includes one-level air chamber, secondary liquid chamber, cushion chamber, and one-level air chamber is arranged on secondary liquid chamber Front end, is provided with fluid communication micropore between secondary liquid chamber and cushion chamber；Cushion chamber is provided with pressure return unit；Level 2 buffering Body is fixed on buffer body fixed cover, and level 2 buffering body is fixedly connected with conical friction plate；

Fixed support is for supporting and installing level 2 buffering body, buffer body fixed cover, conical friction plate, front apron, afterwards gear Plate, sliding axle；Fixed support is fixed on the ground；

Front apron, backboard are fixed on fixed support, and sliding axle passes through buffer body fixed cover, by front apron, buffer body Fixed cover, backboard are linked together, and buffer body fixed cover can be made to be slided on sliding axle；

Conical friction plate is arranged on buffer body fixed cover rear portion, and block is held in brake tightly and disk spring is successively set on taper and rubs Wiping board rear；

Lock shaft is used to control to adjust the distance of conical friction plate, brake holding block and disk spring.

Further specifically, lock shaft is controlled with handwheel.

When using, lock shaft is threaded to correct position by handwheel, brake is held block and conical friction plate not contact condition tightly, and Disk spring is set to be in not compressive state.

A kind of buffer brake structure of the present utility model, its working method is：

During high energy impact events, buffering spacer is struck first, drive level 2 buffering body, buffer body to fix during impact first Set, conical friction plate are integrally moved rearwards by along sliding axle, until conical friction plate is braked, holding block holding is locked, now dish Shape spring is also at compressive state, and dump energy continues to impact level 2 buffering body, and the one-level gas of level 2 buffering body is compressed first Chamber, recompression secondary liquid chamber, and fluid chamber is depressed into cushion chamber, energy absorption work is completed.The cushion chamber of compression is in pressure In the presence of power return unit, the liquid that gradually will be pressed into is restored to secondary liquid chamber；By lock shaft by level 2 buffering body, buffering Body fixed cover, conical friction plate are pushed into forward original position.For bump test prepares next time.

By using above-mentioned technical proposal, buffer brake structure of the present utility model, with following features：

1）Brake structure after one is increased on the basis of traditional level 2 buffering structure can sliding a segment distance；

2）Energy comes to cause greater impact to buffering stand when avoiding directly clashing into, and prevents deformation of timbering；

3）Releasing of brake structure can complete to reset after slip, recover the state to before clashing into；

4）Energy absorption linearly increases after multi-buffer, expands energy-absorbing scope.
