Background technology
In high inclination-angle comprehensive mechanization progress of coal mining,, due to reasons such as face roof fragmentation, wall caving, personnel operation errors, often can cause the bulk spoil to pour in work plane, form and roll cash, fly cash.Because the work plane inclination angle is larger, the spoil block that work plane tumbles is large, speed is high, impact force is strong, and the stabilization of equipment performance such as working surface hydraulic support are impacted, and even causes casualty accident.At present, many Coal Exploitations mostly are rigidity with gear cash device, acting as between spoil and gear cash device " very stiff and demanding ", and this causes spoil large to the instant impact of gear cash device, destructive strong, keeps off the cash weak effect, affects the stability of working face equipment; Due to rigidity gear cash device very flexible, spoil may be stuck between rigidity gear cash device and conveyor pan, causes the conveyer trough blocked, affects the equipment such as Scraper Conveyor in Mining Face and normally moves.In addition, rigidity gear cash device very flexible, complex operation, cost is high, and it is large that this not only strengthens constructor's workload, and affect the stability of working face equipment, affects the safe and efficient production of work plane.Therefore, its improvement and bring new ideas is imperative.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the purpose of the utility model just is to provide a kind of soft waste rock blocking device, can effectively solve existing gear cash device very flexible in high inclination-angle comprehensive mechanization progress of coal mining, complex operation, cost is high, affects the stability of working face equipment, affects the problem of the safe and efficient production of work plane.
the technical scheme that the utility model solves is, comprise belt, assembly pulley, wire rope and jack, belt comprises powerful the first belt and the second belt, the first belt and the connecting plate of the second belt through side are fixed together, the bottom of the first belt and the second belt is placed in respectively on conveyor pan and cable channel, top is in Joining clasp is contained in screens body on the first support telescopic top beam, the wire rope connecting plate is equipped with in the first belt bottom, the wire rope connecting plate is connected with the assembly pulley on being contained in the second support telescopic top beam through the first wire rope, assembly pulley is connected with the piston rod of jack through the second wire rope.
The utility model novel structure is unique, advantages of simple, and easy to operate, cost is low, greatly reduces staff's workload, and the gear cash is effective, and good society and economic benefit are arranged.
Description of drawings
Fig. 1 is structure chart of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
provided by Fig. 1, the utility model comprises belt, assembly pulley, wire rope and jack, belt comprises powerful the first belt 1a and the second belt 1b, the first belt 1a and the connecting plate 2 of the second belt 1b through side are fixed together, the bottom of the first belt 1a and the second belt 1b is placed in respectively on conveyor pan 11 and cable channel 10, top is in Joining clasp 3 is contained in screens body 3a on the first support telescopic top beam 8, wire rope connecting plate 7 is equipped with in the first belt 1a bottom, wire rope connecting plate 7 is connected with the assembly pulley on being contained in the second support telescopic top beam 9 through the first wire rope 5a, assembly pulley is connected with the piston rod of jack 6 through the second wire rope 5b.
In order to guarantee result of use, described assembly pulley comprises the first fixed pulley 4a, movable pulley 4b and the second fixed pulley 4c, the end of the first wire rope 5a is connected with wire rope connecting plate 7, the other end is walked around successively the first fixed pulley 4a, movable pulley 4b and is connected with movable pulley 4b with the second fixed pulley 4c, and movable pulley 4b is connected with the piston rod of jack 6 through the second wire rope 5b;
Described connecting plate 2 is a plurality of, is distributed on the first belt 1a two sides adjacent with the second belt 1b, and the first belt and the second belt are linked to be consistent plane structure.
When the utility model uses, the spoil block that tumbles due to large inclination working surface is large, speed is high, impact force is strong, while adopting rigidity gear cash device, suffered impact force is large, the stabilization of equipment performance such as working surface hydraulic support are impacted, spoil may be stuck between rigidity gear cash device and conveyor pan simultaneously, affecting the equipment such as Scraper Conveyor in Mining Face normally moves, therefore, adopt the soft waste rock blocking device, the spoil that tumbles is played buffering, guiding function, instant impact when reducing spoil and touching with gear cash device, reach the effect of " defeating a force with a tenderness "; Belt is in two Joining clasps are placed in screens 3a on the first support telescopic top beam 8, and Joining clasp can rotate around the first support telescopic top beam; Win wire rope to be fixed in the first belt bottom in succession in lower end, wire rope connecting plate 7 is connected with the assembly pulley on being contained in the second support telescopic top beam 9 through the first wire rope 5a, and assembly pulley 4 is connected with the piston rod of jack 6 through the second wire rope 5b.This can reach flexible motion while making the utility model impacted by spoil within the specific limits, neither can affect its normal operation because departing from conveyor pan, rigid collision that also can be not very stiff and demanding with tumbling at a high speed the spoil generation; Adopt assembly pulley to lead, draw wire rope, increase the sensitivity of gear cash device; Adopt two belts, a belt is taken and is put on the conveyer trough, and a belt is taken and is put on cable channel, with winning in succession, is connected, and can be synchronized with the movement, and when coal-winning machine passes through, can keep off by the extension and contraction control of jack the lifting of cash device; Jack is arranged at the second support telescopic top beam 9, is parallel to the second support telescopic top beam 9, and is connected to jack on the operating grip of support by high-voltage tube, by operation support handle, can control the flexible of jack, thereby control the lifting of gear cash device, easy to operate succinct; Every 10～15 supports of work plane are installed one group of this soft waste rock blocking device, and can coordinate other gear cash device jointly to use, and reach rolling the comprehensive multiple continuous protective action of cash.The utility model novel structure is unique, advantages of simple, easy to operate, cost is low, greatly reduces staff's workload, and the utility model adopts free style to be connected with working surface hydraulic support, the size of belt, the setting position of jack can be adjusted according to the work plane concrete condition, to the strong adaptability of work plane practical condition, the gear cash is effective, and good society and economic benefit are arranged.
