A buffer outer sleeve and a stepped shaft-shaped buffer inner sleeve are sleeved on the piston, the outer surfaces of the buffer outer sleeve and the large diameter part of the buffer inner sleeve are movably sealed with the inner wall of the cylinder body, the small diameter part of the inner buffer sleeve is arranged inside the buffer outer sleeve for movable sealing, and a changeable cavity part between the steps of the buffer inner sleeve and the back end surface of the buffer outer sleeve is communicated with a high-pressure oil passage, so as to form a changeable buffer chamber. The upper part of the cylinder body is connected with a high-pressure energy accumulator, and the high-pressure energy accumulator is communicated with the high-pressure oil passage, so as to absorb and release the energy. The changeable buffer chamber can be compressed and become small so as to squeeze out high pressure oil, buffer a rebounding force and absorbs the rebounding energy, when the chisel rod rebounds by bump so that the knapper and a movable arm protected against being damaged. When the chisel rod hit emptily, the chisel rod can form a two-stage anti-empty hit structure with the fixed buffer chamber of the cylinder body, and when started, the chisel rod can expand to drive the restoration of the piston.
Description
Technical field
The utility model relates to a kind of novel hydraulic destroyer main frame in a kind of engineering machinery.
Background technology
A kind of novel hydraulic destroyer main frame. generally be mounted on the swing arm of engineering truck, utilize compressed nitrogen and hydraulic oil driven plunger bump cutter bar to carry out work. when rubbing, the cutter bar hits object so that during bounce-back, impact and bounce are huge, the capital is shone into loosening each parts of hydraulic crushing main frame, do not have rule thereby irregular hydraulic coupling flows to make it to move in the formation oil circuit, and can significantly reduce impact force.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of can clash into the bounce-back energy by underway absorption cutter bar, and. the energy that can discharge absorption increases a kind of novel hydraulic destroyer main frame of impact force.
The utility model comprises cylinder body and the piston that is placed in one, cylinder body top is provided with high pressure accumulator, there is individual rubber cup high pressure accumulator inside, four outside on four oil ducts and cylinder body oilhole correspondences are arranged at the high pressure accumulator bottom, be connected with high-pressure oil duct simultaneously, high pressure accumulator is fixed with four screws around the bottom.Cylinder head is connected with head, the cutter bar places head and piston to cooperate, outer wall of cylinder block is provided with the reversal valve that connects the external high pressure oil supply source, be provided with fixedly cushion chamber and oil-feed cavity in the shaft shoulder corresponding position of inboard wall of cylinder block upper piston, it is communicated with by high-pressure oil duct and reversal valve, is with in the buffering overcoat that colludes in the front end and the buffering to overlap on the cylinder head piston.The external surface and the inboard wall of cylinder block hydrodynamic reciprocating sealing of this buffering overcoat, the minor diameter part of cover is placed in and cushions hydrodynamic reciprocating sealing in the overcoat in the buffering of multidiameter shape, the external surface of large-diameter portion then with the inboard wall of cylinder block hydrodynamic reciprocating sealing, and the variable cavity position between the outer and buffering overcoat rear end face of the step of cover and high-pressure oil duct are communicated with and constitute the variable buffering chamber in should buffering.
Cover in buffering overcoat of the present utility model and the buffering; and the variable buffering chamber Dou Chong between the high pressure accumulator has hydraulic oil; can compress in cutter bar when bump bounce-back and to diminish and extrude hydraulic oil; buffering and rebound power also has the rubber cup in the high pressure accumulator to absorb the bounce-back energy, significantly reduces the impulse ratio of destroyer main frame and swing arm thereof is more effectively protected equipment.And when the cutter bar attacked and destroy, high pressure accumulator had bounce that the energy that absorbs is discharged because of rubber cup is huge, thereby has increased impact force.
Further specify the utility model below in conjunction with the accompanying drawing example.
Description of drawings; Accompanying drawing is the main structure schematic diagram of implementing.
Embodiment; As shown in the figure, piston 2 places cylinder body 1, and cylinder body 1 afterbody is provided with nitrogen chamber 3, and head is connected with head 4, and cutter bar 5 places head 4 and piston 2 to cooperate.Cylinder body 1 outer wall is provided with the reversal valve 8 that connects the external high pressure oil supply source, on cylinder body 1 inwall. and the shaft shoulder 13 corresponding positions of piston 2 are provided with fixedly cushion chamber 7 and oil suction chamber 6, and it is communicated with by high-pressure oil duct 9 and reversal valve 8.At cylinder body 1 head. be with on the piston 2 in the buffering overcoat that colludes in the front end 10 and the buffering and overlap 11, the external surface and the cylinder body 1 inwall hydrodynamic reciprocating sealing of this buffering overcoat 10, the minor diameter part of the interior cover 11 of the buffering of multidiameter shape is placed in and cushions hydrodynamic reciprocating sealings in the overcoat 10, the external surface that large-diameter portion divides then with cylinder body 1 inwall hydrodynamic reciprocating sealing, and the step place of cover 11 and the variable chamber position between buffering overcoat 10 rear ends and high-pressure oil duct 9 are communicated with and constitute variable buffering chambeies 12 in should buffering.
During operate as normal, utilize the compressed nitrogen driven plunger 2 reach bump cutter bars 5 in the nitrogen chamber 3, bump back hydraulic oil moves after reversal valve 8 feeds the shaft shoulder 13 place's pressurizeds that then can make piston 2 in the oil suction chamber 6, nitrogen is compressed, piston 2 back and forth drives bump cutter bar 5 like this, and buffering overcoat 10 is relative static with cover 11 in the buffering.Behind the broken thing of cutter bar 5 bump during fierce rebounce, its tail end is the front end inner hook part branch of collision buffering overcoat 10 at first, cover 11 can relatively move in buffering overcoat 10 and the buffering, 12 compressions of variable buffering chamber are diminished, the hydraulic oil of the inside is extruded in the high-pressure oil duct 9 oil simultaneously and is charged in the high pressure accumulator 14 and can absorb the bounce-back energy of cutter bar 5 like this in compression process with the rubber cup 15. of high pressure accumulator, avoid the destruction that to shine the severe impact of destroyer, also reduced the vibration to the engineering truck swing arm, the stable buffering effect is very strong.In fact also connect high pressure accumulator 14 outside the cylinder body 1, rubber cup 15 itself and high-pressure oil duct 9 connections, because rubber cup 15 rebounds, storage power can also be released, thereby has improved the impact efficiency like this.
