Description
Technical field:
The utility model relates to a kind of pneumatic hammer, relates in particular to a kind of high power output bump piling pneumatic hammer.
Background technology:
At present, existing pile hammer volume is big, heavy, and air consumption is high, impact force is little, and continuous operation is poor.Inconvenience is carried, and efficient is low.Caused the inconvenience and the waste of source of the gas of construction, especially salvaging more need be used flexible, low power consuming, high efficiency pile hammer, thereby current existing product can not satisfy the demand of work.
The utility model content:
The purpose of the utility model is to overcome the deficiency of above-mentioned prior art and a kind of simple installation, easy to carry is provided, and uses motor-drivenly, flexible, and air consumption is low; Impact force is big, and collects differential connection, and fast row impacts; Continuous operation, differential piston high power output bump piling pneumatic hammer.
The purpose of the utility model can reach through following measure: a kind of high power output bump piling pneumatic hammer, and it comprises outer cylinder, the two ends of outer cylinder connect air inlet loam cake, lower cover respectively; It is characterized in that being provided with upper valve base, lower valve base, inner casing in the outer cylinder and trapping, cover in the air inlet and be provided with the 6th pore, form the 4th cavity between air inlet loam cake and the upper valve base; Upper valve base is provided with the 5th pore, the 4th pore, and lower valve base is a T shape, and lower valve base is provided with the 3rd pore, first pore and endoporus; Inner casing is provided with second pore, forms the 3rd cavity between upper valve base and the lower valve base, is provided with T shape reversal valve in the 3rd cavity; The spool of reversal valve embeds in the endoporus of lower valve base; The spool of reversal valve is provided with the 7th pore, forms first cavity between outer cylinder and the inner casing, is provided with piston in the inner casing; Piston is provided with the corresponding piston hole of valve seat core with lower valve base, piston and trap between form second cavity.
In order further to realize the purpose of the utility model, described lower cover Connection Card pile protection.
Origination action is held up pile hammer directly, blocks pile protection down, and Reversing valve plate cooperates with lower valve base because of gravity and seals at this moment.After the ventilation; Gas is come the inner casing air inlet through upper valve base via the gap of interior outer cylinder, and apply piston makes it go upward to the lower valve base air vent, behind the sealed porosity; Utilize the Piston Compression upper gas to promote Reversing valve plate sealing upper valve base; Thereby conversion air flue, gas get into inner casing through lower valve base rapidly, and apply piston makes it descending; Break away from the sealing plunger of lower valve base during to lower dead center, open exhaust opening, get rid of the decompression of piston upper air, the Piston Compression air resets Reversing valve plate and seals lower valve base simultaneously, and the conversion air flue makes piston stroking upward once more, the Automatic Cycle action.
The utility model is compared with prior art can produce following good effect: the reversal valve of the utility model has increased spool, so in the process that piston falls, saved the air consumption of LAP, effectively utilizes source of the gas; Realize low pressure, high impact forces, and structure design is tight; Reduced volume and weight greatly, energy-conservation, high efficiency; The utility model is convenient for carrying, and can realize continuous high power output, high speed impact.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of the position of walking to top dead centre of the utility model;
Fig. 3 is the structural representation of the reversal valve of the utility model.
The specific embodiment: elaborate below in conjunction with the specific embodiment of accompanying drawing to the utility model:
Embodiment: a kind of high power output bump piling pneumatic hammer is (referring to Fig. 1-Fig. 3); It comprises outer cylinder 3; The two ends of outer cylinder 3 be threaded respectively air inlet loam cake 1, lower cover 6; Be provided with upper valve base 2, lower valve base 4, inner casing 9 in the outer cylinder 3 and trap 5, upper valve base 2, lower valve base 4, inner casing 9 and trap 5 axially cooperate fastening.Air inlet loam cake 1 is provided with the 6th pore 23; Form the 4th cavity 22 between air inlet loam cake 1 and the upper valve base 2, upper valve base 2 is provided with the 5th pore 17, the 4th pore 16, and lower valve base 4 is a T shape; Lower valve base 4 is provided with the 3rd pore 15, first pore 11 and endoporus 12; Inner casing 9 is provided with second pore 14, forms in the 3rd cavity 21, the three cavitys 21 between upper valve base 2 and the lower valve base 4 and is provided with T shape reversal valve 8; The spool 25 of reversal valve 8 is the pin-and-hole matched in clearance with the endoporus 12 of lower valve base 4, and the spool 25 of reversal valve 8 is provided with the 7th pore 20.Form first cavity 13 between outer cylinder 3 and the inner casing 9.Be provided with piston 10 in the inner casing 9, piston 10 is provided with the valve seat core 26 corresponding piston holes 24 with lower valve base 4, piston 10 big footpath and inner casing 9 pin-and-hole matched in clearance, path and the 5 pin-and-hole matched in clearance of trapping.The piston 10 and formation second cavity 18 between 5 of trapping.Lower cover 6 Connection Card pile protections 7 are used for the clamping timber.
Before the ventilation work, initial position is that reversal valve 8 is descending, the 3rd pore 15 of the valve block 19 sealing lower valve bases of reversal valve 8, and first pore 11 overlaps with the 7th pore 20 and ventilates simultaneously; Piston 10 is down, and trap 5, the second cavitys 18, second pore 14, first cavity 13, the 4th pore 16 of sealing communicates.Like Fig. 1, during work, working gas gets into from the 6th pore 23 of air inlet loam cake 1, comes second cavity 18 via the 4th cavity 22, the 5th pore 17, the 3rd cavity 21, the 4th pore 16, first cavity 13, second pore 14.It is up to promote piston 10; The valve seat core 26 of lower valve base 4 gets in the piston hole 24; When sealing first pore 11; Piston 10 compressed air promote valve block 19 to the upper valve base 2 of reversal valve 8 rapidly and seal the 4th pore 16, and valve block 19 pulling spools 25 make the 7th pore 20 not overlap fully with first pore 11 simultaneously, realize closed state.Like Fig. 2, because the sealing of the 4th pore 16, gas is via the 5th pore 17, the 3rd cavity 21, the 3rd pore 15 direct apply pistons 10, makes piston 10 downward accelerated motions and impacts the realization of card pile protection and do work.Because first pore 11, the 7th pore 20 do not overlap fully,, piston 10 do not have gas to waste before the core 26 so lifting off a seat.Thereby realized energy-conservation, efficiently the acting.When piston 10 front ends are trapped 5 the time to sealing, the gas of beginning compression stroke 18 makes gas it is pushed into lower valve base 4 sealings the 3rd pore 15 reach original state, thereby realize circulation via second cavity 18, first cavity 13, the 4th pore 16 effect reversal valves 8.
