Description
Technical field
this device relates to oneconveyer stretcher, constant force tension device at the bottom of especially a kind of mine belt conveyor V-type.
Background technology
In the tunnel of coal mine belt conveyor work, tunnel rises and falls in large " V " type, during heavy duty running, load-transfer device is put near the low-lying place of " V " type, the adhesive tape of upper strata carrying becomes slack near the low-lying place of " V " type, folding accumulation, thus cause frequent generation to spread the phenomenon of coal in a large number, cause belt conveyer normally cannot carry raw coal.To Problems existing analysis and by the actual observation to scene, find that two ends, groove low-lying place, adhesive tape lane are due to upper, downhill slope is comparatively large and deliver raw coal Action of Gravity Field, during belt conveyer heavy duty running, upper strata adhesive tape is when the section of going up a hill near head is run, speed compared with normal speed is little, and when the section of going down the hill near tail is run, upper strata tape speed compared with normal speed is large, thus cause belt conveyer lower floor adhesive tape by larger tension force tensioning, lower floor's tape portion place is ground to belt conveyer upper supporting roller frame, the adhesive tape of upper strata carrying becomes lax near the low-lying place of groove, folding accumulation, occur serious spreading coal phenomenon.
This large " V " type tunnel is after belt conveyer installs, and at noload test run, all are normal, and after running a period of time, problem occurs.The scheme of current solution has: in each slope section, scheme one arranges that a collapsible band conveying connects, head tail series connection overlap joint; Scheme two whole process arranges a conveyer, and add Multipoint Drive, have drive point at chain-drive section, also there is one or more drive point at middle part.Scheme one be each slope point arrange one can the defeated machine of belt, head tail series connection overlap joint.Each conveyer is equipped with a set of actuating device, a set of tightening device and a set of automatically controlled and fender guard, and equipment manufacturing cost is high, and regular job maintenance aspect, needs more human users and maintenance, also high to security requirement.
Summary of the invention
The object of this patent is to provide constant force tension device at the bottom of a kind of mine belt conveyor V-type, solve load-transfer device relax in mine " V " type tunnel, folding pile up cause spread coal problem.
For achieving the above object, what this patent adopted is technical scheme is: constant force tension device at the bottom of a kind of mine belt conveyor V-type, comprise conveyer belt apparatus, it is characterized in that, comprise a set of and steel rope deflection sheave group of conveyer stretcher, weight suspension gear, tensioning dolly;
Conveyer stretcher is arranged on the V-type bottom of conveyer belt apparatus, described conveyer stretcher comprises tensioning support and first and turns to cylinder, tensioning support two inside establish sliding rail, first turns to cylinder to be arranged on the load-transfer device working direction end of tensioning support, and first turns to cylinder to pass through to support fixing independent of the direction of tensioning support;
Described tensioning dolly establish second to turn to cylinder, roller and wire rope fixing device, roller drives tensioning dolly to move forward and backward along sliding rail, second turns to cylinder height to turn to cylinder height lower than first, load-transfer device passes through above tensioning support with working direction, then turn to the reversing sense of a forward direction to extend around first, then turn to cylinder to turn to advance oppositely around second;
Described weight suspension gear comprises overarm, weight, winch and fixed pulley group, described overarm is established two fixed pulley group a side by side, it is weight below fixed pulley group a, weight is established pulley b, the close wall side setting pulley c of fixed pulley group a, fixing winch is established below fixed pulley c, described steel rope deflection sheave group comprises vertical fixed pulley d and the fixed pulley e of horizontal positioned, steel rope one end is fixed on the wire rope fixing device of tensioning dolly, the other end walks around fixed pulley e, fixed pulley d, a pulley of fixed pulley group a, pulley b, another pulley of fixed pulley group a, pulley c, finally be wrapped on the reel of winch.
Be in free state by weight tensioning dolly is pulled to load-transfer device tightens, solve the relaxation problem of load-transfer device.And the elastic elongation of load-transfer device can be absorbed and Permanent extension.

Detailed description of the invention
Below in conjunction with accompanying drawing and instantiation, the present invention is further illustrated:
Constant force tension device at the bottom of a kind of mine belt conveyor V-type, comprises conveyer belt apparatus, it is characterized in that, comprises a set of and steel rope deflection sheave group of conveyer stretcher, weight suspension gear, tensioning dolly;
Conveyer stretcher is arranged on the V-type bottom of conveyer belt apparatus, described conveyer stretcher comprises tensioning support 19 and first and turns to cylinder 17, tensioning support 19 two inside establish sliding rail 14, first turns to cylinder 17 to be arranged on the load-transfer device working direction end of tensioning support 19, and first turns to cylinder 17 to be fixed by the reverse support independent of tensioning support 19;
Described tensioning dolly 13 is established second turn to cylinder 12, roller 18 and wire rope fixing device, roller 18 drives tensioning dolly 13 to move forward and backward along sliding rail 14, second turns to cylinder 12 height to turn to cylinder 17 height lower than first, load-transfer device 15 passes through above tensioning support 12 with working direction, then turn to the reversing sense of cylinder 17 forward direction to extend around first, then turn to cylinder 13 to turn to advance oppositely around second;
Described weight suspension gear comprises overarm 1, weight 5, winch 8 and fixed pulley group, described overarm 1 is established two fixed pulley group a2 side by side, it is weight 5 below fixed pulley group a2, weight 5 is established pulley b3, the close wall side setting pulley c6 of fixed pulley group a2, fixing winch 8 is established below fixed pulley c6, described steel rope deflection sheave group comprises vertical fixed pulley d4 and the fixed pulley e11 of horizontal positioned, steel rope one end is fixed on the wire rope fixing device of tensioning dolly 13, the other end walks around fixed pulley e11, fixed pulley d4, a pulley of fixed pulley group a2, pulley b3, another pulley of fixed pulley group a2, pulley c6, finally be wrapped on the reel 7 of winch 8.
In conveyer operational process, weight is in free state, and tensioning dolly is pulled to conveying belt tension by steel rope, although tension weight also has force of inertia to produce when conveyer starts and shut down.Analysis shows, the acceleration/accel of weight is much smaller than acceleration due to gravity, and thus, can be similar to that to regard tensile force as constant, namely the tensile force of weight is constant.Under the effect of weight, this tightening device can make tensioning dolly be subjected to displacement to absorb elastic elongation and the Permanent extension of load-transfer device.
