Abstract
The utility model relates to a pneumatic shock hammer. One end of a cylinder body (7) with an air duct is connected with an air distributing valve, and the other end is connected with an exhaust valve. The inside of the air distributing valve body (9) is placed with an air distributing valve core (10), and a push rod (6) passes through an air distributing valve base (8) and a piston (5) and then is connected with an exhaust valve core (3). An upper cap (11) of the air distributing valve with central holes are arranged on the top end of the air distributing valve base (8), and the middle of an air inlet valve body is concave and corresponds to the central hole of the upper cap (11) of the air distributing valve. The top end of air exhaust valve body (4) abutting against a drill rod sleeve (2) is provided with a port V. The utility model uses air as power and can safely work under specific environment.
Description
The utility model belongs to percussion tool, particularly a kind of percussion tool with pneumatic actuation.
Present broken object often adopts hydraulic impact hammer, this device in particular surroundings as: when working under high temperature, the high oxygen condition,, easily burn, explode, bring harm to the production and the person when the pipeline of its device takes place damagedly.
The purpose of this utility model provides a kind of pneumatic striking mechanism, and it has carries out crushing operation safety in particular surroundings, and characteristics simple to operate.
For reaching above-mentioned purpose, the utility model comprises intake valve, distributing valve, cylinder and air bleeding valve, and the end that cylinder body has the cylinder of breather line is connected with distributing valve, and the other end is connected with air bleeding valve.It is characterized in that laying the distribution spool in being provided with the distribution valve body of a plurality of passwaies, push rod passes distributing valve seat and is connected with exhaust plug with piston; The distributing valve loam cake that has centre bore is contained in the top of distributing valve seat, and the medial recess of air inlet valve body is corresponding with distributing valve loam cake central hole location; Exhaust valve is provided with the passway near drill steel cover top end.
Passway I, II, III and IV on the distribution valve body is crisscross arranged in that its side is relative, and communicates separately with gas port in the cylinder.
The centre bore of distributing valve loam cake is small one and large one through holes of two diameters, and aperture is below macropore.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model structure diagram;
Fig. 2 is the structure enlarged drawing of A portion among Fig. 1.
1 is drill steel among the figure, and 2 is the drill steel cover, and 3 is exhaust plug, 4 is exhaust valve, and 5 is piston, and 6 is push rod, 7 is cylinder, and 8 is distributing valve seat, and 9 are the distribution valve body, 10 are the distribution spool, and 11 is the distributing valve loam cake, and 12 are the air inlet spool, 13 for the air inlet valve body, I, I ', II, II ', III, III ', IV, IV ' and V, V ' be the passway.
Pneumatic immpacting device comprises air bleeding valve, cylinder, distributing valve and intake valve four parts composition.Exhaust plug 3 is connected with drill steel 1, and exhaust plug 3 is installed in the exhaust valve 4, forms air bleeding valve; Piston 5 is placed in the cylinder 7 that has breather line in the cylinder body; Distributing valve seat 8 is placed in cylinder 7 tops, and distribution spool 10 is placed on the distributing valve seat 8, the distributing valve loam cake 11 that has centre bore is installed on its top is formed distributing valve; Air inlet spool 12 is placed in the centre bore of distributing valve loam cake 11, and air inlet valve body 13 connects to form intake valve with distributing valve.One end air bleeding valve of cylinder 7 connects, and the other end connects distributing valve.When drill steel 1 contacts and oppresses broken thing, because its reaction force makes drill steel 1 up, and it is up to promote exhaust plug 3, piston 5, push rod 6 and air inlet spool 12, open the passway V ', and make air inlet spool 12 leave the centre bore of distributing valve loam cake 11, with INO.At this moment compressed air enters distributing valve loam cake 11 through intake valve, enters the breather line that the passway I in the distribution valve body 9 is communicated with it through cylinder 7, and the bottom promotion piston 5 that arrives piston 5 in other end I ' passway of this pipeline is up; Making the former air that retains on piston 5 tops overlap 2 top ends V ' passway through exhaust valve 4 near drill steel arranges to atmosphere; When piston 5 continues up, open III ' passway, the breather line of the cylinder 7 of while gas through being communicated with it, enter the bottom of distribution spool 10 from the other end III passway of this pipeline, up to promote distribution spool 10, close the I passway on the distribution valve body 9 simultaneously, open its passway II, the breather line that compressed air is communicated with it through cylinder 7 is on the top of the other end II ' arrival piston 5 of this pipeline.When piston 5 is up open III ' passway after, and then open the V passway, make the other end V ' passway of the breather line of compressed air through being communicated with of piston 5 bottoms enter atmosphere with it.This moment, the gas pressure of piston 5 bottoms reduced rapidly, and the pressure on piston 5 tops is constant, and the pressure on piston 5 its tops promotes drill steel 1 down, to realize crushing operation.In piston 5 descending processes, open the IV ' passway on the cylinder wall earlier, compressed air is breather line on the cylinder 7 that communicates with it, come out from the other end IV passway of this pipeline, enter distribution spool 10 tops, descending to promote distribution spool 10, close II passway on the distribution valve body, open the I passway simultaneously, promptly finish a working cycles.Pneumatic striking mechanism can be finished crushing operation under above-mentioned continuous working cycles.
For making gas accurately be distributed in the upper and lower part of cylinder 7 by the job requirement of pneumatic striking mechanism, passway I, II, III and the IV on the distribution valve body 9 is distributed in that its side is relative to be crisscross arranged, and communicates separately with breather pipe road junction in the cylinder 7.
The centre bore of distributing valve loam cake 11 is small one and large one through holes of two diameters, and aperture is convenient to lay air inlet spool 12 below macropore, and distributing valve loam cake 11 and air inlet spool 12 are common to constitute inlet channels, and opens or closes inlet channel.
