Abstract
The invention relates to a multi-air leg supporting structure of a pneumatic hammer drill. A main shaft is mounted in a shaft sleeve in a penetration mode. One end of one side, outside of the shaft sleeve, of the main shaft is connected to a bending beam. One end of one side face of the bending beam is rotationally provided with a connecting shaft sleeve. The other end of the other side face of the bending beam is rotationally provided with another connecting shaft sleeve. Two regulating shafts are respectively rotationally mounted inside the two connecting shaft sleeves in a penetration mode. According to the invention, the shaft sleeve of the lower end surface of the machine body of the hammer drill is connected to the two regulating shafts of the upper end part of two air leg telescopic rods through the main shaft, bending beam and connecting shaft sleeves. A pressing fork of the lower end of each air leg telescopic rod is pressed against a proper position by operators during usage, and after stably supported, the hammer drill starts to work. Two pressing forks and two pressing tips are pressed against the ground together so that a stable support is realized on a hard ground surface or a ground surface with poor flatness, labor intensity is further reduced, and working efficiency is increased.
Description
Technical field
The invention belongs to hammer drill field of support structures, especially a kind of pneumatic type hammer drill many air legs braced structures.
Background technology
Hammer drill is divided into pneumatic type, electrodynamic type, internal combustion type and fluid pressure type, pneumatic type wherein orders about piston with compressed air and impacts forward in the cylinder, drill rod is cut a hole and hits rock, it is widely used in Drilling explosive hole in stone drifting and various rock drilling operation, is the Chinese medicine facility in the stoneworks such as mine, railway, traffic, water conservancy construction.Because hand-held drifter will have very large strength to help, violent vibration directly passes in the person, people is made to be easy to fatigue, unhealthful, in order to improve this problem, people develop for pusher leg drill, its structure is: comprise air leg expansion link 9, top fork 10 and top 11, top fork is arranged on air leg expansion link lower end, air leg expansion link lower surface in the fork of top installs can stretch top, during use, a bending connecting rod 7 is fixed in air leg expansion link upper end 8, the upper end of this bending connecting rod connects a regulating shaft 6, this regulating shaft is rotatably installed in the axle sleeve 2 of hammer drill body 1 lower surface installation, operating personnel are by the flow of adjustments of gas, top is made to pitch and toply withstand ground, instead of the support of manpower, thus significantly reduce labour intensity.In actual use, when ground is harder, single air leg to make dynamics limited, cause during operating personnel's Drilling and still comparatively require great effort.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of pneumatic type hammer drill many air legs braced structures provide and make great efforts, reducing labour intensity further.
The technical scheme that the present invention takes is:
A kind of pneumatic type hammer drill many air legs braced structures, comprise air leg expansion link and hammer drill, described air leg expansion link upper end connects a regulating shaft by bending connecting rod, axle sleeve is integrally made in the lower surface of described hammer drill body, it is characterized in that: in described axle sleeve, install a main shaft, this main shaft side end be positioned at outside axle sleeve connects a bending beam, installation one connecting bushing is rotated in one end of one side of this bending beam, the other end of this bending beam another side rotates installs another connecting bushing, rotates respectively and install regulating shaft described in these two connecting bushings.
And described connecting bushing connects the bending beam surface of homonymy by a rotary joint.
Advantage of the present invention and good effect are:
In the present invention, installation one main shaft is rotated in the axle sleeve of hammer drill body lower surface, one side end of this main shaft connects a bending beam, installation one connecting bushing is rotated in one end of one side of this bending beam, the other end of this bending beam another side rotates installs another connecting bushing, rotate respectively in these two connecting bushings and install regulating shaft described in, during actual use, the regulating shaft of two air leg expansion link upper ends is respectively charged in two connecting bushings by operating personnel, by fork top, the top of air leg expansion link lower end in place, regulate top, make its supporting & stablizing, thus two top fork and two top jointly withstand ground, hard ground or the poor ground of planeness achieve stable support, reduce further labour intensity, improve operating efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the syndeton schematic diagram of main shaft, bending beam, connecting axle and air leg expansion link upper end.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is further described, and following embodiment is illustrative, is not determinate, can not limit protection scope of the present invention with following embodiment.
A kind of pneumatic type hammer drill many air legs braced structures, as shown in Fig. 1 ~ 2, comprise air leg expansion link 9 and hammer drill 1, described air leg expansion link upper end connects a regulating shaft 6 by bending connecting rod 7, axle sleeve 2 is integrally made in the lower surface of described hammer drill body, innovation of the present invention is: install a main shaft 3 in described axle sleeve, this main shaft side end be positioned at outside axle sleeve connects a bending beam 4, installation one connecting bushing 12 is rotated in one end of one side of this bending beam, the other end of this bending beam another side rotates installs another connecting bushing, rotate respectively in these two connecting bushings and install regulating shaft described in.Described connecting bushing connects the bending beam surface of homonymy by a rotary joint 5.
When the present invention uses:
1. the regulating shaft of two air leg expansion link upper ends is respectively charged in two connecting bushings by operating personnel.
2. then just the top fork of air leg expansion link lower end pushes up in place.
3. control valve, makes toply stretch out and hold out against ground.
4. fine tuning valve, makes the drill rod of hammer drill aim the place.
5. start hammer drill, start working.
In the present invention, hammer drill is connected the regulating shaft of two air leg expansion link upper ends respectively by main shaft, bending beam and connecting bushing by the axle sleeve of its body lower surface, during use, operating personnel by fork top, the top of each air leg expansion link lower end in place, start working after supporting & stablizing, due to two top forks and two top jointly withstand ground, hard ground or the poor ground of planeness achieve stable support, reduce further labour intensity, improve operating efficiency.
Claims (2)
1. pneumatic type hammer drill many air legs braced structures, comprise air leg expansion link and hammer drill, described air leg expansion link upper end connects a regulating shaft by bending connecting rod, axle sleeve is integrally made in the lower surface of described hammer drill body, it is characterized in that: in described axle sleeve, install a main shaft, this main shaft side end be positioned at outside axle sleeve connects a bending beam, installation one connecting bushing is rotated in one end of one side of this bending beam, the other end of this bending beam another side rotates installs another connecting bushing, rotates respectively and install regulating shaft described in these two connecting bushings.
