Abstract
A kind of AGV dollies buffer unit, by setting elastic force-applying device and sliding block in hook attachment for trailer, when AGV dolly speeds change, sliding block drives elastic force-applying device to deform upon generation elastic buffer, the speed of trailer is changed than shallower, avoid goods on trailer from toppling over because of effect of inertia, the utility model is simple in construction and service free, original rigidly connected hook attachment for trailer is solved when speed changes, the goods on trailer is easy to topple over technical barrier on the ground.
Description
Technical field:
It the utility model is related to delaying for mechanical field, more particularly to Transport Machinery, particularly a kind of AGV dollies connection trailer
Punch mechanism.
Background technology
In the prior art, AGV dollies are directly connected to trailer below with coupling hook.Dolly needs in operation
During acceleration or deceleration, particularly encounter when stopping in emergency, because having drawn more piece cargo tow tractor behind AGV dollies, often save cargo tow tractor
Height at 1 meter or so, in the presence of inertia, goods be easy to topple on the ground, to product exist very big hidden danger of quality.
Utility model content
The purpose of this utility model is to be directed to drawbacks described above of the prior art, there is provided one kind is simple in construction and without protecting
Foster buffer unit, when solving AGV dollies traveling and stopping, the jiggly technical barrier of rear portion trailer.
Its main operational principle is to absorb impulsive force caused by Vehicle Speed change by elastic deformation so that is dragged
The steady acceleration or deceleration of car.
To realize above-mentioned purpose of utility model, the utility model uses following technical scheme：Shell is hung including tail and is used for
The tail connected with AGV dollies hangs fixing hole, it is characterised in that the tail hangs enclosure and sets cushion chamber, the cushion chamber court
Closed to one end of AGV dollies, the both sides tail of the cushion chamber, which is hung in shell, is provided with sliding groove, is provided with the cushion chamber
Sliding block, the both sides of the sliding block are provided with alignment pin, and alignment pin, which extends in the sliding groove and hangs shell with tail, forms slip
Structure, the sliding block can be moved horizontally along the sliding groove, and the sliding block is applied towards the one side inside cushion chamber and an elasticity
One end connection of power apparatus, the other end of the elastic force-applying device connect the cushion chamber blind end, and the sliding block direction is dragged
The one side connection trailer of car.When AGV dollies slow down or brake, trailer can still be travelled forward due to inertia with original speed, from
And promote sliding block to be moved along sliding groove to AGV dollies direction, and elasticity of compression force application apparatus when sliding block moves, elastic force-applying device
Its reaction force also progressively slows down the speed of trailer until it is consistent with the small vehicle speeds of AGV while stress produces deformation.
Further, the elastic force-applying device is compression spring.By spring, the reaction force caused by compression is realized
Trailer steadily slows down.
Further, one end of the cushion chamber towards trailer is provided with buffering chamber lid, and described sliding block passes through extension rod
The buffering chamber lid connection trailer is stretched out, is cased with back-moving spring on the extension rod, described back-moving spring one end connects the cunning
On the inside of block other end connection buffering chamber lid.When AGV dollies are at the uniform velocity travelled or stopped, sliding block is in compression spring and back-moving spring
Intermediate region in the slip section that sliding groove is limited under collective effect, by the back-moving spring of installation, AGV dollies slow down
Or during brake, trailer can compress compression spring therein with movable slider, by spring, the reaction force caused by compression, which is realized, drags
Car steadily slows down, and when AGV dollies accelerate, trailer can compress back-moving spring therein with movable slider, be produced by spring by compression
Reaction force realize that trailer steadily accelerates so that trailer can held stationary in AGV dolly acceleration or decelerations.
Further, the elastic force-applying device is pressure buffer strut.By air by compression caused by reaction force
Realize that trailer steadily slows down.
Further, described elastic force-applying device is adjustable spring, and described adjustable spring one end is fixedly connected on sliding block
On, the other end is fixedly connected on the cushion chamber blind end.When AGV dollies are at the uniform velocity travelled or stopped, sliding block is in adjustable spring
In the presence of in sliding groove limited slip section intermediate region, due to adjustable spring when being compressed or being stretched all
The reaction force opposite with force direction can be produced because of deformation, when AGV dollies slow down or braked, trailer can drive cunning
Block compresses adjustable spring, realizes that trailer steadily slows down by spring reaction force caused by compression, when AGV dollies accelerate, drags
Car can drive sliding block pull adjustable spring, by spring be stretched caused by reaction force realize that trailer steadily accelerates so that
Trailer can held stationary in AGV dolly acceleration or decelerations.
The utility model compares with prior art, and its effect is positive and obvious.In the utility model, pass through elasticity
Deformation absorb trailer because of inertia and caused by impulsive force so that trailer in AGV dolly acceleration or decelerations can held stationary,
Goods on trailer is steady and ground will not be poured over because of inertia, and this device has the advantages that simple in construction and service free.
