Description
Technical field
The utility model belongs to road machine apparatus field, more particularly to a kind of buffering of the anti-rebounce of hydraulic lithotriptor
Device.
Background technology
Hydraulic lithotriptor is widely used in road maintenance engineering, and its function is by original water before spreading or repairing road surface again
Road face carries out impact type and crushed, so as to subsequent construction.Hydraulic lithotriptor is using fluid pressure as power, to impact impact piston
Reciprocating kinetic energy impact pick rod carrys out fractured rock, because rock and pick rod all have certain elasticity, therefore, in broken rock mistake
The bounce-back of pick rod is certainly existed in journey, particularly when rock is not broken, i.e., rock does not absorb most of impact energy, root
According to conservation of energy principle, the energy of bounce-back is just bigger.
Hydraulic lithotriptor impact energy is big, if pick rod impact energy directly rebounds onto impactor body and stone crusher large arm,
Then to the very big destruction of the generation such as hydraulic pressure rubble impactor, large arm and bearing chassis.In order to bear very big bounce-back punching
Hit power, it is desirable to which bearing chassis tonnage is big, and this provides for improved the cost of machine.Therefore, it is necessary to suitable cushion is designed to absorb
Possessed energy when pick rod rebounds.
The content of the invention
To solve existing technical problem, this is filled using a kind of buffering of the anti-rebounce of hydraulic lithotriptor of new offer
Put, the buffer unit absorbs rebounce energy using hydraulic cushion, is sufficiently used impact energy, improves hydraulic pressure rubble
The system effectiveness of machine, shock attenuation result is good, service life length.
Technical solution adopted in the utility model is：
A kind of buffer unit of the anti-rebounce of hydraulic lithotriptor, including head and cylinder body, the head end are provided with resistance to
Grinding set, the head inside other end are provided with cushion collar, and one end is provided with buffing pad inside cushion collar, is formed between buffing pad and cushion collar
There is buffering grease chamber, described buffing pad one end is connected with cylinder body, and cylinder interior is provided with high-pressure oil pipe, the high-pressure oil pipe and buffering
Grease chamber is connected, and pick rod, the cushion collar, buffing pad and cylinder interior centerline are provided with the head inside center line
Provided with impact piston, the impact piston afterbody is provided with nitrogen chamber.
The beneficial effects of the utility model：The device is combined by hydraulic oil and nitrogen chamber energy storage double acting, significantly
Rebounce energy is absorbed, energy is stored in the form of hydraulic pressure and compressed nitrogen, improves the service efficiency of system,
Meanwhile hydraulic pressure shock attenuation result is good, service life length.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model
Wherein：1- pick rods；2- wear-resistant sleeves；3- heads；4- cushion collars；5- buffing pads；6- impact pistons；7- cylinder bodies；8- is high
Pressuring oil pipe；9- buffers grease chamber；10- nitrogen chambers.
Embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer
The embodiment of type is set forth in.
A kind of buffer unit of the anti-rebounce of hydraulic lithotriptor, including head 3 and cylinder body 7, the end of head 3 are provided with
Wear-resistant sleeve 2, the inside other end of head 3 are provided with cushion collar 4, and the inside one end of cushion collar 4 is provided with buffing pad 5, buffing pad 5 and cushion collar
It is connected between 4 formed with buffering grease chamber 9, described one end of buffing pad 5 with cylinder body 7, the inside of cylinder body 7 is provided with high-pressure oil pipe 8, described
High-pressure oil pipe 8 is connected with buffering grease chamber 9, and pick rod 1, the cushion collar 4, buffering are provided with the inside center line of head 3
For seat 5 with being provided with impact piston 6 at the inside center line of cylinder body 7, the afterbody of impact piston 6 is provided with nitrogen chamber 10.
As shown in figure 1, when the pick rod 1 in the buffer unit acts on road concrete or other hard ore surfaces, punching
When hitting the impact progress broken rock operation of pick rod 1 of piston 6, if rock is not broken, i.e., concrete or ore do not sponge greatly
Part impact energy, there must be part impact energy bounce-back to pick rod 1, on the one hand cause the bounce-back of impact piston 6 and compress afterbody nitrogen
The energy storage of air chamber 10, the bounce-back of another aspect pick rod 1 promote cushion collar 4 to move right, the buffering oil between cushion collar 4 and buffing pad 5
Hydraulic oil in room 9 is pressurized, and its pressurised hydraulic is returned in high pressure accumulator and energy storage by high-pressure oil pipe 8, is buffering grease chamber 8
In the presence of high pressure liquid force feed, the ball rebound velocity of pick rod 1 will be zero rapidly, so as to play the cushioning effect of anti-rebounce；To make
1 continuous broken rock of pick rod, hydraulic oil and the high pressure nitrogen of nitrogen chamber 10 in accumulator it is dual release can act synergistically under, effectively
Bounce-back energy is make use of, improves the efficiency of breaking rock of stone crusher.
One embodiment of the present utility model is described in detail above, but the content is only of the present utility model
Preferred embodiment, it is impossible to be considered as being used to limit practical range of the present utility model.It is all to be made according to present utility model application scope
Equivalent change with improve etc., all should still belong within patent covering scope of the present utility model.
