Description
[technical field]
The utility model relates to mining equipment field, especially relates to a kind of bont for promoting mining cantilever support driving surface scrapper conveyor.
[background technology]
Known, mining cantilever support has good integrity, supporting safety, can certainly move, the lightweight and advantage conveniently installed and used, and it is at roof cracking, easily wall caving, three-soft seam, compared with high spud angle inclinations, high-dipping, roof weighting is fast and pressure is excessive and need the working face of coal seam of the shortening distance of face roof under control normally to work, but, in actual applications, passing due to cantilever support driving surface scrapper conveyor is pass by the artificial hydraulic prop that uses substantially entirely, when therefore performing passing operation in process of production, it is passed fulcrum and can only be located on hydraulic prop or old man's spoil, soft by coal mine work area base plate, the factor impact that ponding is more, the passing of cantilever support driving surface scrapper conveyor is abnormal difficult, it very easily occurs that scrapper conveyor pricks the phenomenon at the end, thus be not only unfavorable for the normal operation of scrapper conveyor, but also consequently reduce the service life of scrapper conveyor, add the cost of maintenance maintenance and the labour intensity of workman.
[summary of the invention]
In order to overcome the deficiency in background technology, the utility model discloses a kind of scrapper conveyor bont, described device can prevent scrapper conveyor from pricking the generation of end phenomenon by actv. while effectively reducing labor strength.
For achieving the above object, the utility model adopts following technical scheme:
A kind of scrapper conveyor bont, described device comprises telescopic jack, chain and one-way lock; The termination, one end of described telescopic jack is provided with for the locating dowel pin of correspondence hanging in cantilever support back timber slideway, the other end termination of telescopic jack is provided with for the chain that connect corresponding to scrapper conveyor, and the hydraulic tubing loop of telescopic jack is provided with one-way lock.
Further, the outer wall of described telescopic jack is provided with the hanging block fixing one-way lock for correspondence.
Further, described one-way lock is bolted on the outer wall of telescopic jack.
Further, the adaptor union place between described hydraulic tubing and one-way lock is provided with o type circle and back-up ring.
Further, the adaptor union place between described hydraulic tubing and one-way lock is provided with stifled, elbow, U-shaped card, O type circle and back-up ring successively.
Further, described one-way lock is corresponding with two that for subsequent use of cantilever support maneuvering valve is drawn or high-pressure rubber pipe to be connected.
Owing to adopting technical scheme as above, the utility model has following beneficial effect:
Scrapper conveyor bont described in the utility model is not only rational in infrastructure, is easy to assembling, easy to use, and dependable performance, safety durable, and cost is lower; Described device can prevent scrapper conveyor from pricking the generation of end phenomenon while effectively reducing labor strength; thus actv. protects scrapper conveyor delivery system; improve the safety of downhole production; and improve service life and the production efficiency of scrapper conveyor accordingly, save the maintenance maintenance cost of scrapper conveyor.
[accompanying drawing explanation]
Fig. 1 is schematic diagram of the present utility model.
In figure: 1, telescopic jack; 2, slideway; 3, locating dowel pin; 4, chain; 5, hydraulic tubing; 6, one-way lock.
[detailed description of the invention]
Can explain the present invention in more detail by the following examples, open the purpose of this utility model is intended to protect all changes and improvements within the scope of the utility model, and the utility model is not limited to the following examples:
Scrapper conveyor bont by reference to the accompanying drawings described in 1, described device comprises telescopic jack 1, chain 4 and one-way lock 6; The termination, one end of described telescopic jack 1 is provided with for the locating dowel pin 3 of correspondence hanging in cantilever support back timber slideway 2, and namely telescopic jack 1 can be hung in the slideway 2 of back timber by locating dowel pin 3, and can move around along slideway 2; The other end termination of telescopic jack 1 is provided with for the chain 4 that connect corresponding to scrapper conveyor, thus chain 4 can be utilized scrapper conveyor and telescopic jack 1 to be linked together, and is reached through telescopic jack 1 and lifts by crane the object promoting scrapper conveyor; Hydraulic tubing 5 loop of telescopic jack 1 is provided with the one-way lock 6 possessing locking function, namely after scrapper conveyor is pulled up, one-way lock 6 can be utilized to lock the hydraulic tubing 5 of telescopic jack 1, thus actv. ensure that scrapper conveyor can not glide, simultaneously, in the described device not used time, locking after piston rod can being regained, thus reach protection piston rod, corresponding raising scrapper conveyor service life and production efficiency, save maintenance maintenance cost, improve the object of downhole production safety;
As required, by bolt, described one-way lock 6 can be fixed on the outer wall of telescopic jack 1, simultaneously, adaptor union place between hydraulic tubing 5 and one-way lock 6 sets gradually stifled, elbow, U-shaped card, O type circle and back-up ring, thus the adaptor union place that actv. has ensured between hydraulic tubing 5 and one-way lock 6 there will not be and oozes dew phenomenon; As required, the hanging block being used for corresponding fixing one-way lock 6 can be set at the outer wall of telescopic jack 1, the hanging block being weldingly fixed on telescopic jack 1 outer wall namely can be utilized to be connected and fixed one-way lock 6.
When implementing scrapper conveyor bont described in the utility model, only first need utilize locating dowel pin 3 by hanging stable for telescopic jack 1 in the slideway 2 of back timber, and make telescopic jack 1 move to the top of scrapper conveyor along slideway 2, scrapper conveyor and telescopic jack 1 correspondence link together by recycling chain 4, then just can stir cantilever support maneuvering valve handle and control telescopic jack 1 action, thus reach the object of Synchronous lifting scrapper conveyor; Wherein, two or a high-pressure rubber pipe can be drawn from for subsequent use of cantilever support maneuvering valve, make it be connected with one-way lock 6, thus reach quickly for one-way lock 6 introduces the object of propulsion source.
The non-detailed portion of the utility model is prior art, therefore the utility model is not described in detail.
