Description
Technical field the utility model relate to a kind of can with the supporting multi-functional twin-stage air leg of hammer drill.
Before background technology the utility model is made, mainly form by the two-stage cylinder with the structure of the supporting twin-stage air leg of hammer drill.The one-level cylinder is made up of outer tube, guide pin bushing, interior pipe, piston and bracket component etc., and secondary cylinder is made up of interior pipe, guide pin bushing, piston rod, piston, a claw assembly etc.But it can not satisfy user's different demands by simple reconfiguration, and can't realize simple and easy protective function of mine working, is difficult to realize a tractor serves several purposes.
Summary of the invention task of the present utility model is: provide a kind of can with the supporting multi-functional twin-stage air leg of hammer drill.It can be directly and the supporting use of hammer drill; Also can be by user's oneself operating habit, commutation is used behind the renewal part, thereby satisfies user's different demands.In addition, the utility model can also be made pillar by renewal part and use, to realize the simple and easy supporting of mine working.
The purpose of this utility model is achieved through the following technical solutions: a kind of can with the supporting multi-functional twin-stage air leg of hammer drill, form by the two-stage cylinder.The one-level cylinder is made up of outer tube, guide pin bushing, interior pipe, piston, support etc., and secondary cylinder is made up of interior pipe, guide pin bushing, piston rod, piston, end cap, a claw assembly etc.Its structural feature is: an end of piston rod adopts the internal and external threads structure, and in vent cap is arranged so that pillar time spent renewal part is used and does in commutation.As being pulled down with the transverse arm assembly on it, support is changed to bearing; To prop up claw assembly and pull down and be changed to coupling seat, and the transverse arm assembly of packing into, can realize the operation that commutates, satisfy user's different demands.Be changed to carriage and the transverse arm assembly on support and its pulled down, and will prop up claw assembly and pull down and be changed to supporting base, the pillar that then can make mine timbering uses, and realizes a tractor serves several purposes.

The specific embodiment:
As shown in Figure 1, the utility model relates to a kind of can with the supporting multi-functional twin-stage air leg of hammer drill, form by the two-stage cylinder.The one-level cylinder is made up of outer tube (12), guide pin bushing (13), interior pipe (11), piston (5) and support (1) etc., and secondary cylinder is made up of interior pipe (11), guide pin bushing (15), piston rod (10), piston (18,21), end cap (14), a claw assembly (17) etc.Air leg links with hammer drill by support (1), transverse arm assembly (2), and support (1) is used thread connection with outer tube (12), and with tight loop (20) locking, contacts end sealing mat (3) sealing.Fix with glue between guide pin bushing (13) and the outer tube (12), guide pin bushing (15) is enclosed within on the piston rod (10).Piston ring (6) and sealing ring (4) are housed on the piston (5), piston is equipped with piston ring (9) on (18,21), be contained on the piston rod (10) with sealing ring (8), fixing with pad (22) and nut (7), seal with sealing ring (19) between piston rod (10) and piston (18).Dust ring (16) is housed on the end cap (14), is screwed on the outer tube (12).Propping up claw assembly (17) connects with the internal thread of piston rod (10).
Twin-stage air leg when work at first is that the one-level cylinder drives secondary cylinder and promotes support together and rise, and secondary cylinder motion behind certain stroke continues to promote support and rises, thereby realizes the twin-stage function.When air leg need extend, compressed air enters upper chamber of air cylinder from the air inlet duct of transverse arm assembly (2) and support (1), outer piston moves downward in promoting, when piston (5) and guide pin bushing (13) when contacting, first order stroke finishes, continue to move downward and promote piston rod (10) by piston (18,21), when piston (18) and guide pin bushing (15) when contacting, the end of second level stroke.When air leg need be withdrawn, emit compressed air, conduct oneself with dignity by hammer drill then or add manpower and withdraw by former air inlet duct.
When the user need be commutated operation, can support among Fig. 1 (1) and transverse arm assembly (2) be pulled down by shown in Figure 2, change bearing (23) and make to support usefulness; To prop up claw assembly (17) and pull down, and change coupling seat (24), coupling seat (24) is screwed on the external screw thread of piston rod (10), transverse arm assembly (2) is contained on the coupling seat (24) again, and air leg then connects with hammer drill by coupling seat (24), transverse arm assembly (2).Air leg operating principle after the commutation is constant, when just air leg need extend, compressed air is that the air inlet duct from transverse arm assembly (2), coupling seat assembly (24) enters, and enters former cylinder epicoele shown in Figure 1 by the duct in the piston rod (10) then, promotes the air leg elongation.
With the pillar time spent that air leg transforms mine timbering into, can support among Fig. 1 (1) and transverse arm assembly (2) be pulled down by shown in Figure 3, change carriage (25), be used for supporting tunnel end face; To prop up claw assembly (17) and pull down, change supporting base (26), be contained on the external screw thread of piston rod (10), be used for ground supports; Unidirectional air inlet switch (27) is arranged on the supporting base (26), be used for unidirectional air inlet and reverse sealing.The operating principle of pillar is constant, just compressed air enters former cylinder epicoele shown in Figure 1 by the air inlet duct of unidirectional air inlet switch (27) and supporting base (26) and piston rod (10), the elongation of promotion pillar, withstand the tunnel end face, close unidirectional air inlet switch (27) then, can play support action.When pillar internal compression air has leakage, can replenish automatically by unidirectional air inlet switch (27), thereby play long supporting.
