Abstract

The utility model discloses a novel hydraulic-nitrogen joint action breaking hammer. The breaking hammer is characterized in that: the breaking hammer comprises a chisel (1) and a front body (9), a guide sleeve (2) and a chisel holder bush (3) are mounted in the front body (9), the chisel (1) is arranged in the guide sleeve (2) and the chisel holder bush (3) on the front body (9), and is integrated with a piston (8) which can move up and down in a hydraulic cylinder (11) of the breaking hammer, the piston (8) is arranged in the hydraulic cylinder (11), a front chamber (10) and a rear chamber (12) are arranged between the piston (8) and the hydraulic cylinder (11), a valve cap (4), a spool (5) and a valve housing (6) form a reversing valve which passes through the hydraulic cylinder (11) and is communicated with the piston (8), and a sealed nitrogen chamber (13) is arranged at the rear end of the piston (8). The utility model has the advantages that: the irregular hydraulic pressure in an oil passage is decreased, and meanwhile, the recoil force applied on a machine, such as a hydraulic excavator, and an operator is decreased; during stroke, partial power is supplied to the piston, the nitrogen-inflating hammering force is completely supplied by nitrogen, and thereby the breaking efficiency is increased.

Description

A kind of novel hydraulic nitrogen synergy quartering hammer
Technical field:
The utility model relates to a kind of quartering hammer, particularly a kind of hydraulic pressure and the symphyogenetic quartering hammer of nitrogen.
Background technology:
Hydraulic breaking hammer is the New Hydraulic Impact Machine that grows up the sixties in 20th century.It is to be power source with the hydraulic pump, and oil liquid pressure is a power, and reciprocating motion of the pistons output percussion power utilizes the piston of high-speed motion to remove to impact bit shank, carries out the hydraulic impact machine of crushing operation, has obtained extensive use in the engineering field with the mining circle.The external at present hydraulic breaking hammer of producing respectively has superiority, and in general, the development of its performance mainly contains following trend:
(1) impact energy is big.In order to improve crushing efficiency, impactor should provide big as far as possible impact energy, and this is a leading indicator of weighing the impactor performance.
(2) capacity usage ratio height.
(3) for ease of maintenaince with change parts.
(4) piston stroke is adjustable, to change frequency of impact and impact energy, makes impact parameter be suitable for fragmented rock stiffness conditions and the impact resistance wanted.
(5) introduced " intelligent broken impactor technology ".Can decide output, the continuous control impact energy according to the resistance that last time hits.Make all corresponding reduction of shock wave, resonance, heating and vibrations, and the life-span of drill steel is prolonged, noise descends.See that from Beijing engineering machinery exhibition in 2003 hydraulic breaking hammer of Korea S has accounted for very big ratio in China hydraulic breaking hammer market, and the producer of many production hydraulic breaking hammers is all for selling abroad on a commission basis, domestic oneself product is few.Can see that from this fact the hydraulic breaking hammer of China is mainly produced by introducing external product and technology, or be improved on the basis of product abroad and become oneself product, also not have ability to carry out the development and the exploitation of new product.
The utility model content
The technical problems to be solved in the utility model provides a kind of novel hydraulic nitrogen synergy quartering hammer, mainly is the nitrogen chamber that is provided with a space sealing in the rear end of piston.
The utility model major technique characteristics are: mainly comprise drill steel, precursor, in the described precursor fairlead is housed, drill steel retainer lining, drill steel is arranged in the fairlead and drill steel retainer lining on the precursor, the piston that moves up and down in drill steel and the quartering hammer hydraulic cylinder is formed one, and piston places in the hydraulic cylinder, is provided with ante-chamber and back cavity between piston and the hydraulic cylinder; Valve gap, spool and clack box are formed a reversal valve, pass hydraulic cylinder and are communicated with piston, and the rear end of piston is provided with the nitrogen chamber of a space sealing.
Technical characterstic of the present utility model also is: in the nitrogen chamber, be provided with a piston ring between hydraulic cylinder and the piston.
The beneficial effects of the utility model: reduce irregular hydraulic coupling in the oil circuit, reduce simultaneously to loading mechanical ratio such as hydraulic crawler excavator and operator's recoil strength; For piston provides part power, nitrogen explosion type hammer hitting power then provides by nitrogen fully, improves and hits crushing efficiency during stroke.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model
The specific embodiment
In the specific embodiment the utility model is described in further detail as shown in the figure below, it mainly comprises: drill steel 1, precursor 9, in the described precursor 9 fairlead 2 is housed, drill steel retainer lining 3, drill steel 1 is arranged in fairlead 2 and the drill steel retainer lining 3 on the precursor 9, the piston 8 that moves up and down in drill steel 1 and the quartering hammer hydraulic cylinder 11 is formed one, piston 8 places in the hydraulic cylinder 11, be provided with ante-chamber 10 and back cavity 12 between piston 8 and the hydraulic cylinder 11, valve gap 4, spool 5 and clack box 6 are formed a reversal valve and are passed hydraulic cylinder 11 connection pistons 8, be provided with the nitrogen chamber 13 of a space sealing in the rear end of piston 8, in the nitrogen chamber 13, be provided with a piston ring 7 between hydraulic cylinder 11 and the piston 8.
1, drill steel
Have another name called drill rod, chisel, clink etc., be with the quartering hammer hydraulic cylinder in the piston that moves up and down form the facility of one, utilize the hydraulic pressure of hydraulic crawler excavator can convert mechanical blow energy to.Adopt the high-quality special rolling-mill section, after heat treatment tough and tensile, wear-resisting, easy fracture not and is hit thing and is directly contacted.
Usually be divided into pyramid, taper shape, chock shape and four kinds of specifications of blunt shape according to the nose shape difference, to adapt to various different operating modes.As specific use, also have and inlay for example taper drill steel of hard steel core.
2, reversal valve
Mainly contain 4. valve gap, 5. spool and 6. clack box form.The control back cavity is switched on or switched off hydraulic oil, realizes reciprocating motion of the pistons.
Many grades of hydraulic hammers promptly pass through to regulate the reversal valve opening point and then change piston stroke in the market, realize the purpose of mechanical type accent energy and frequency modulation.
3, precursor
Support the whole machine body of quartering hammer.Inside be equipped with keep the correct operator of drill steel to fairlead 2. impact guiding with the buffering drill steel drill steel retainer lining 3..
4, hydraulic cylinder
There are former and later two working chambers hydraulic cylinder inside, by through bolt precursor, nitrogen chamber being coupled together, form the space of reciprocating motion of the pistons, is the heart component of hydraulic breaking hammer, there is high requirement in the chamber, front and back to flow, finishes the high-low pressure cycle operation with minimum oil hydraulic system.
5, piston
Hydraulic hammer relies on the kinergety of piston to realize hitting the blow energy fractured rock of acquisition.The piston situation directly influences the life-span of hydraulic breaking hammer.The important indicator of piston is the hardness of piston, toughness, surface accuracy and the concentricity of material.
