Description
Technical field
The utility model relates to air drill, particularly gas leg type air drill, specifically a kind of fast detachable air leg.
Background technology
The air leg structure of existing pusher leg drill and type of attachment unreasonable, in use procedure, dismounting is inconvenient, just can must complete with special tool, and workload is large, causes loading and unloading maintenance difficult, affects production efficiency.And hammer drill is indispensable important facility in modernization construction, be widely used, frequency of utilization is high.The structure of existing air leg cannot adapt to the demand of production development, is thus badly in need of improving.
Summary of the invention
For overcoming the defect of prior art, be conducive to the development of production and construction, the utility model provides a kind of fast detachable air leg, realize convenient disassembly, be easy to change wearing and tearing or aging part, thus shorten maintenance time, enhance productivity, meet the needs of related industry development.
The technical solution of the utility model is as follows: fast detachable air leg comprises frame portions, outer tube, piston component, tracheae assembly, telescopic tube assembly, top fork assembly, also comprise header assemblies, locking device and screw plug, outer tube left end connects the frame portions with intake and exhaust duct, right-hand member tube connector holder assembly, header assemblies is made up of bottom nozzle and bottom nozzle cover plate, the two is connected by bolt and spring washer circle, header assemblies is loaded on outer tube by screw thread, be locked by locking device, outer tube is equipped with piston component and telescopic tube assembly, telescopic tube assembly outer end is pitched assembly with screw thread with top and is connected, tracheae assembly inserts telescopic tube assembly by the screwed hole of support body termination, connect with the duct on support body and form complete intake and exhaust duct, tracheae assembly outer end is loaded in screw plug, screw plug screw thread is fixed on support body.
Hammer drill operating principle: the air flue entering Pneumatic supporter frame body during hammer drill work in the co-controlling compressed air of control valve and reversal valve, arrive left air chamber, promoting piston component makes telescopic tube assembly and top fork assembly stretch out from outer tube, produce active force to the strong point, end reaction provides end thrust to hammer drill, realizes rock drilling, change airintake direction, outer tube return by telescoping tube, so comes and goes and repeats, realize rock drilling operation.
Compare with prior art, the beneficial effects of the utility model are as follows: 1, be provided with header assemblies.Bottom nozzle cover plate bolt is connected with bottom nozzle, connect reliable, easy to maintenance, only need back out bolt, unload bottom nozzle cover plate, telescopic tube assembly and outer tube part can be taken out, checked or changed, being achieved quick-detachment, being reduced labour intensity, shorten the maintenance duration, improve production efficiency; 2, header assemblies is contained on outer tube with thread forms, and uses locking device fixing and locking, is connected firmly, reliable operation; 3, tracheae assembly inserts from support body ends screw hole, and its outer end is placed in screw plug, backs out screw plug, can load and unload tracheae assembly, efficient and convenient.
