Abstract
The utility model relates to an automatic recorder of a fully-mechanized working face advancing distance, which is suitable for automatic measurement and recording of the fully-mechanized working face advancing distance in the process of coal mining. The automatic recorder comprises a transmission device and a worm-reducer connected with the transmission device, wherein the worm-reducer is provided with an idler wheel counter, a one-way driver is arranged between the transmission device and the worm-reducer, and a flexible cable connected with a base of a hydraulic support is arranged on the transmission device. The working face advancing distance is measured through accumulating the advancing distance of a drag conveyor, and the accumulated result is recorded on the idler wheel counter, therefore, the utility model realizes real-time and accurate automatic measurement and recording of the working face advancing distance. The utility model has simple, compact and reasonable structure as well as high stability.
Description
Technical field
The utility model relates to a kind of fully-mechanized mining working and advances apart from automatic recorder, is particularly useful for the automatic measurement and the record of fully-mechanized mining working advance distance in the process of coal mining.
Background technology
In the actual production process of colliery, the propelling of coal-face is apart from being the underlying parameter that calculates mine output and definite working face mining position, also be that work plane ore deposit pressure manifests in analysis and the research exploitation process, gas is migrated and the important evidence of water burst rule, thereby grasp the motion and the disrumpent feelings rule of overlying strata, safe, the efficient back production of work plane is provided instruct and foundation.Yet for this parameter measurement simple and practical instrument of neither one all the time.Work at present face advances the main measuring method of distance to have two kinds: the firstth, and after work plane forms, in the gallery of both sides, be spaced a distance and mark, perhaps directly on lane group rib, indicate distance, determine the propelling distance of work plane with this; Another kind of then be that cutter number and cylinder according to the coal-winning machine coal cutting cuts dark calculating.Yet these two kinds of methods all exist the shortcoming that measure error is big and can not reflect advance of the face distance in real time.Therefore, be necessary to invent a kind of can the measurement automatically in real time and exactly and the instrument of writing task face propelling distance.
Summary of the invention
The purpose of this utility model is the weak point that overcomes in the prior art, provides a kind of fully-mechanized mining working simple in structure, easy to operate, that result of use is good to advance apart from automatic recorder.
For achieving the above object, fully-mechanized mining working of the present utility model advances and comprises transmission device apart from automatic recorder, the worm reducer that links to each other with transmission device, worm reducer is provided with the roller counter, be provided with unidirectional driver between transmission device and the worm reducer, transmission device is provided with the flexible cable that is connected on the hydraulic support foundation.
Described transmission device comprises the axle sleeve that is fixed on the drag conveyor spillplate, be provided with the spring rotating shaft in the axle sleeve, be wound with its outer end on the spindle nose of spring rotating shaft and be fixed in flexible steel wire on the base of hydraulic support, the top of the spindle nose of spring rotating shaft is provided with the spring that is fixed in the axle sleeve; Described flexible steel wire external packets is wrapped with the cover skin.
Beneficial effect: worm reducer of the present utility model is provided with the roller counter, utilize the process characteristic that draws moving hydraulic support in the work plane coal mining process and pass drag conveyor, the propelling distance of coming the surveying work face by the passing distance of accumulative total drag conveyor, and with the outcome record of accumulative total on the roller counter, realized that the advance of the face is apart from automatically measuring accurately in real time and record.System architecture is simple, compact and reasonable, and stability is high.
Description of drawings
Accompanying drawing is a theory structure schematic diagram of the present utility model.
1-roller counter, 2-flexible cable, the rotating shaft of 3-spring, the unidirectional driver of 4-, 5-worm reducer, 6-axle sleeve, 7-spring, 8-spindle nose, 9-flexible steel wire, the 10-flexibility cover skin that can contract
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
As shown in the figure, the utility model conducts the advance distance of drag conveyor for roller counter 1 by the flexible steel wire 9 that is connected on spindle nose 8 and the hydraulic support foundation, it comprises transmission device, transmission device comprises the axle sleeve 6 that is fixed on the drag conveyor spillplate, be provided with spring rotating shaft 3 in the axle sleeve 6, be wound with its outer end on the spindle nose 8 of spring rotating shaft 3 and be fixed in flexible steel wire 9 on the base of hydraulic support, wherein, flexible steel wire 9 external packets are wrapped with the cover skin, and the top of the spindle nose 8 of spring rotating shaft 3 is provided with the spring 7 that is fixed in the axle sleeve 6; The worm reducer 5 that links to each other with transmission device, worm reducer 5 is provided with roller counter 1, is provided with unidirectional driver 4 between transmission device and the worm reducer 5, and transmission device is provided with the flexible cable 2 that is connected on the hydraulic support foundation.During assembling, need prior flexible steel wire 9 to be wrapped on the spindle nose 8 with about 1 meter, when the jack promotion drag conveyor of hydraulic support moved forward, flexible steel wire 9 will drive spring rotating shaft 3 and rotate, and by worm gear reducer transmission device 5 advance distance is accumulated in the roller counter 1 again; When hydraulic support is drawn forward when moving, spring 7 in the spring rotating shaft 3 promptly can drive rotating shaft 3 reverse rotations, flexible steel wire 9 is wrapped on the spindle nose 8 again, because the effect of unidirectional driver 4, the worm reducer 5 of this moment can't rotate, thereby hydraulic support draws the distance of moving also just can not be transmitted on the roller counter 1, and then has avoided repeat count.When drag conveyor moved forward once more, roller counter 1 continued counting, circulation so repeatedly, and the propelling of work plane is apart from being accumulated on the roller counter 1 the most at last.
