Specific implementation mode
Further explanation is done to the utility model below in conjunction with the accompanying drawings.
The utility model, which discloses a kind of support of open coal mine Weight type drag conveyor and moves, sets device, includes mainly weight
7, several parts such as weight bottomland thorn 11, hydraulic pressure beetle haulage system, hydraulic cylinder sleeve 6, support leg 10 and linkage rope 8.
As shown in Fig. 1 .1 and 1.2, drag conveyor 2 is respectively arranged on the left side and the right side connecting hole 1, and hydraulic stem 4 passes through connection
Pin 3 is connect with connecting hole 1.Weight 7 is mainly the material composition with greater density of metal or metalloid, specific size
It is determined by actual use material character, the main function of weight 7 is provided for single unit system with ground friction using own wt
Frictional force big as possible；7 bottomland of weight thorn, 11 insertion earth's surface is hereinafter, main purpose is when device elapses drag conveyor 2
Enough frictional force is provided for device, avoids that weight 7 is caused to move backward since 2 weight of drag conveyor is excessive, ensures passage
Reliability；Support leg 10 is monomer liquid cylinder pressure, provides power by emulsion power pack, bottom is contacted by chassis 9 with ground, top
It is connect with hydraulic cylinder sleeve 6, lubricating oil or ball 12 (as shown in Figure 2) is added between hydraulic cylinder 5 and hydraulic cylinder sleeve 6,
Reduce frictional force, weight 7 can be lifted away from ground by the stretching of support leg 10；The power of hydraulic pressure beetle haulage system comes from emulsion power pack, work
Move or realize that itself moves forward before pushing drag conveyor 2 by hydraulic stem 4 when making；Linkage rope 8 for connect hydraulic stem 4 with
Support leg 10 realizes that support leg 10 is moved synchronously with passage hydraulic cylinder 4.
When normal work, weight 7 is placed in earth's surface, and ground thorn 11 gos deep into stratum, and support leg 10 is located at 5 tail portion of hydraulic cylinder, is in
Contraction state is not contacted with ground.Weight 7 and 11 guarantee drag conveyor 2 of ground thorn are not walked because of double-ended shearer coal cutting
Or slip row.
Double acting hydraulic cylinder can be used in hydraulic pressure beetle haulage system and support leg 10.
As shown in Fig. 3 .1 and 3.2, when needing to elapse drag conveyor 2, emulsion power pack is the back cavity feed flow of hydraulic cylinder 5,
So that hydraulic stem 4 is stretched out, drag conveyor 2 is pushed to be set to Forward, meanwhile, linkage rope 8 drives support leg 10 to move synchronously forward, directly
To moving to 5 front end of hydraulic cylinder.
As shown in Fig. 4 .1 and 4.2, after completing the passage of drag conveyor 2, emulsion power pack stops the back cavity for hydraulic cylinder 5
Feed flow starts the back cavity feed flow for support leg 10, so that 10 hydraulic stem of support leg is stretched out, the support leg chassis 9 of 10 bottom of support leg
Weight 7 is then lifted away from ground by landing, and ground thorn 11 leaves stratum, and frictional force reduces over the ground.Then emulsion power pack is hydraulic cylinder
5 ante-chamber feed flow makes hydraulic stem 4 retract, and hydraulic cylinder 5 is moved forward with weight 7, realizes that weight 7 self moves and sets.
As shown in Fig. 5 .1 and 5.2, after the completion of the shifting of weight 7 is set, hydraulic cylinder sleeve 6 and support leg 10 revert to hydraulic pressure again
5 tail portion of cylinder, support leg 10 are retracted, and weight 7 lands, and ground thorn 11 reinserts stratum, and device completes one cycle, starts normal work
Make, support force is provided for drag conveyor 2.
The one or one group breast that the support leg 10 and the hydraulic power of hydraulic pressure beetle haulage system are controlled from integrated system
Change pump station.Pumping plant is support leg hydraulic cylinder and beetle haulage system hydraulic pressure in order according to aforementioned activities, by different hydraulic oil pipes
Cylinder provides the emulsion of different pressures, different flow, control cylinder pressure, passage direction and passage speed.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and deformations can also be made, these change
The scope of protection of the utility model is also should be regarded as into deformation.
