Description

A kind of combined anti-seismic moves stent
Technical field
The present invention relates to coal mine machinery equipment technical fields, and in particular to a kind of combined anti-seismic moves stent.
Background technology
Colliery is often placed stent in each tunnel intersection, is hung on stent for solid in underground work at present Determine the brake shoes as shown in Figure 6 of mine car, when facilitating tunnel intersection mine car excessive, mine car is fixed;Since colliery is in underground Operation, often because the coal cinder movement generation quick-fried phenomenon of coal, some collieries in tunnel can drop on stent or normal In the course of work, stent can be encountered, so as to stent be caused to damage, it is necessary to which the stent of damage transported to ground, repair is good or more The stent renewed, then transports to underground again again, since stent volume is excessive, it is not easy to carry, it is necessary to which special mine car is transported It is defeated, so as to cause bothersome laborious, increase production cost, and during stent is transported to destination by worker from underground parking lot, Since tunnel inner volume is small, usually normally walking can be hard, and transporting supports are more not easy, in some instances it may even be possible to be fallen down worker, be pacified Full accident.
The content of the invention
More than technical problem is based on, the present invention provides a kind of combined anti-seismics to move stent, so as to solve existing colliery The technical issues of transporting bracket is difficult.
The technical solution adopted by the present invention is as follows:
A kind of combined anti-seismic moves stent, vertical between pedestal and cross bar including pedestal and the cross bar being arranged on pedestal Connecting rod is provided with, the cross bar bottom level is provided with track, and multiple suspensions that can be slided along track are provided in track and are filled It puts, the hook that suspension arrangement includes body, is arranged on the hanging rod of body lower part and is arranged on hanging rod bottom;Hanging rod both sides are located at Rail inferior portion has been horizontally disposed with connecting plate, and through hole is provided on connecting plate, and through hole is corresponded on track and is provided with connecting hole, through hole and Connecting hole is bolted;
In orbit, both sides are both provided with longitudinal wheel to the body card below body, and the both sides of body are provided with lateral wheel, (the first back-moving spring is provided between lateral wheel and body, spring protection shell, lateral wheel are provided on the outside of (the first back-moving spring Lower section idler wheel is provided with by shaft;The hooked ends are welded with mousing-hook;
The connecting rod is threaded rod, is provided on pedestal and matches somebody with somebody with the matched threaded hole of connecting rod, connecting rod with threaded hole It closes, connecting rod is connected with pedestal;The connecting rod passes through cross bar, and connecting rod is located at cross bar and top nut has been installed above and below And lower nut, top nut coordinate respectively with connecting rod with lower nut, connecting rod and cross bar are fixed;The track both ends open, Track is located at opening and is provided with for the sealing plate of folding opening;
The pedestal lower part is provided with vibration-damped table, and vibration-damped table includes tablet and is arranged on the bottom plate of flat plate bottom, bottom plate and Multigroup return spring is vertically arranged between tablet, shell is provided with outside return spring, it is high that outer cover height is less than return spring Degree;The tablet is movably connected with the base.
In conclusion by adopting the above-described technical solution, the beneficial effects of the invention are as follows:
1st, (the first back-moving spring is provided in lateral wheel of the present invention to carry out hook certain delay when stent rocks Punching reduces the amplitude that hook rocks, the brake shoes on hook or instrument is avoided to drop;Hooked ends are provided with mousing-hook, make Brake shoes or instrument are not easy to skid off hook, can further prevent brake shoes or instrument from dropping, and worker is made to need to use When, it can be quickly found out and use or even avoid security incident;
2nd, invention hook can be moved along track, adjusted the distance between each hook so as to facilitate, avoided suspension body When accumulating larger instrument, other is caused to link up with situation about can not use;The connecting plate set on hanging rod can regulate it is each After the distance between hook, hook is fixed, when avoiding coal outburst raw, links up with and mutually slides, cause to break instrument or make instrument It drops from hook;
3rd, the longitudinal direction wheel and lateral wheel that the present invention is set can be during moveable hooks, and reduction hook has between track Frictional force makes mobile more convenient, the abrasion between reduction component;
4th, when carrying, the present invention can be splitted into pedestal, cross bar and track, connecting rod, suspension arrangement, vibration-damped table, no Occupied space of the present invention in transportational process, convenience in transport can only be reduced, and when worker carries in tunnel, Ke Yifen Multiple people repeatedly carry, and reduce the labor intensity of worker, ensure the safety of worker;After pervious holder part damage, by It is integral type in stent, entire stent can only be transported to ground maintenance or replacement, and the present invention need to only transport the part of damage It is defeated to arrive ground maintenance or replacement, save transportation cost and maintenance cost;
5th, connecting rod of the present invention is connected with whorl of base, while realizing easy to disassemble, can also be existed by connecting rod The depth of base threaded hole come adjust the present invention height;
