Abstract

The utility model discloses a ram quick -witted high -order sway bar by force, including prevent inclining the outer tube with prevent the inner tube that inclines, the outer pipe box of preventing inclining is preventing inclining the inner tube outside, all there is a connection otic placode outside end of prevent the inclining outer tube and the inner tube of preventing inclining, has a compression spring at the inner tube outside cover of preventing inclining, is equipped with outer extension stand pipe at the outer tube of preventing inclining between the inner tube with preventing inclining, the stand pipe both sides end of extending outside is punished and do not is provided with spacing bolt I and spacing bolt II. In the installation, satisfy great installation distance's requirement through the extension of outer extra long stand pipe, can guarantee A type frame and all install with the cantilever crane that the danger of removing personnel high altitude construction from is and simple to operate when the extreme lower position, the length that can shrink work needed voluntarily of lifting through the cantilever crane after the installation is because much more more the shrink meeting of outer extension stand pipe reserves out buffer space for compression spring, so be difficult for killing. All parts all are the structure, and processing is convenient, low in manufacturing cost, the mechanical component fault rate is low, the reliability is high.

Description

The high-order sway bar of a kind of dynamic compaction machinery

One, technical field

The utility model belongs to technical field of engineering machinery, is specifically related to a kind of high-order sway bar of dynamic compaction machinery.

Two, background technology

Dynamic compaction machinery is a kind of engineering machinery for stiffening basic ground, its operating principle is after hammer ram is risen to certain altitude, utilize detacher device or other way, make hammer ram freely falling body or fall fast, being kinetic energy the transform gravitational energy of hammer ram, is that soft ground is tamped by ballistic work when hammer ram lands kinetic transformation.Owing to being Condition of Sudden Unloading when dynamic compaction machinery works, jib can rebound fast, makes the danger of the oriented tipping backwards of jib.In order to prevent the bounce-back of jib, the main way adopting low level sway bar or high-order sway bar at present.Because the low level sway bar arm of force is short, want to overcome jib bounce and must strengthen overstriking sway bar, and the support zone of jib also will be strengthened, cost is higher and local pressure is comparatively large, easily produces stress raisers or local fatigue destruction.Current high-order sway bar is the development of low level sway bar, and could install after needing A type frame to lift, it is also dangerous that installation position sets high inconvenience; And limit by the factor such as mounting distance and operating distance, the distance that Compress Spring is compressed is short, cushion insufficient, easily kill, form rigid rod, cause sway bar to bend the problem such as damage.

Three, summary of the invention

The purpose of this utility model is to provide the high-order sway bar of a kind of dynamic compaction machinery easy for installation, that not easily kill.

The technical scheme of employing of the present utility model is: the high-order sway bar of dynamic compaction machinery comprises pipe in anti-dumping outer tube and anti-dumping, anti-dumping outer tube sleeve tube outside in anti-dumping, in anti-dumping outer tube and anti-dumping, all there is connection otic placode the termination, outside of pipe, in anti-dumping, tube outside cover has Compress Spring, outer lengthening guide pipe is provided with between pipe in anti-dumping outer tube and anti-dumping, lengthen termination place, guide pipe both sides outside and be provided with caging bolt I and caging bolt II respectively, anti-dumping outer tube has the long and narrow chute adapted with caging bolt I, pipe there is the long and narrow chute adapted with caging bolt II in anti-dumping.During installation, first Compress Spring is sleeved in anti-dumping on pipe, outer lengthening guide pipe is sleeved in anti-dumping outer tube also spacing with caging bolt I, more also rear caging bolt II of using is spacing above two parts suits.

The utility model obtains larger mounting distance by the stretching, extension of outer lengthening guide pipe, can ensure that A type frame and jib are all installed when extreme lower position, remove the danger of personal height operation from and easy for installation, the length that automatically can be retracted to need of work is lifted by jib after installation, because the contraction of outer lengthening guide pipe can reserve more cushion space to Compress Spring, so not easily kill.

The utility model has the following advantages:

1, mounting distance is long, can remove the danger of personal height operation from and easy for installation;

2, the cushion space of Compress Spring greatly not easily kills;

3, all parts are all structural member, easy to process, low cost of manufacture;

4, mechanical component failure rate is low, reliability are high.

Five, detailed description of the invention

The high-order sway bar of dynamic compaction machinery comprises pipe 3 in anti-dumping outer tube 1 and anti-dumping, anti-dumping outer tube 1 to be enclosed within anti-dumping outside pipe 3, in anti-dumping outer tube 1 and anti-dumping, all there is connection otic placode the termination, outside of pipe 3, Compress Spring 4 is had near engaging lug plate portion cover outside pipe 3 in anti-dumping, outer lengthening guide pipe 2 is provided with between pipe 3 in anti-dumping outer tube 1 and anti-dumping, lengthen termination place, guide pipe 2 both sides outside and be provided with caging bolt I 5 and caging bolt II 6 respectively, anti-dumping outer tube 1 has the long and narrow chute adapted with caging bolt I 5, pipe 3 there is the long and narrow chute adapted with caging bolt II 6 in anti-dumping.During assembling, first Compress Spring 4 is sleeved in anti-dumping on pipe 3, outer lengthening guide pipe 2 is sleeved in anti-dumping outer tube 1 also spacing with caging bolt I 5, above 2 parts are set with and use caging bolt II 6 spacing.Anti-dumping outer tube 1 is that the pipe of two part different-diameters is combined into, and connected by adapter flange between tubule and extra heavy pipe, outer lengthening guide pipe 2 only extends in the thick tube part of anti-dumping outer tube 1.Compress Spring 4 is for lengthening spring, in anti-dumping, pipe 3 both sides are provided with stay bolt, outside the flange of nut pipe 3 termination in anti-dumping of two stay bolts, through Compress Spring 4, at the shank of bolt other end, Compress Spring 4 is locked by baffle plate and nut, and determine prestressing force and the buffer distance of spring.

Main frame is installed, first the connection otic placode of anti-dumping outer tube 1 bearing pin is connected with host A type frame 8 top, again the utility model is stretched from the other end, now the outer guide pipe 2 that lengthens can stretch, thus obtain larger mounting distance, can ensure that A type frame and jib are all installed when extreme lower position, then with bearing pin 7, pipe in anti-dumping 3 and jib 9 be fixed.

After the utility model installation, utilize lifting the utility model and being automatically retracted to active length of jib, now the outer guide pipe 2 that lengthens can shrink, and reserves more cushion space to Compress Spring 4, it is longer that Compress Spring 4 can design, and buffering effect is better.The object of the high-order sway bar reach easy for installation, not easily killing.
