Description
Technical field
The utility model relates to a kind of car puller spring piston type tensioner.
Background technology
Perpendicular, slope mouth mechanization facility are to connect the important step that perpendicular, inclined shaft hoisting and well head or stage transport.Realizing bank head machinery, interlockization, is to improve perpendicular, inclined shaft hoisting ability, to improve labor strength, the important means that reduces the operation number and keep the safety in production.Car puller is the main mechanization facility of well head, in most mines use is arranged.And the cable type car puller is because of simple in structure, and action easily, and is easy to maintenance, reliable, and stroke and bending be the characteristics such as unrestricted all, in metallurgical mine, use the most general.Its haulage cable of cable type car puller needs often to regulate its length in use because of elongation.Traditional control method is to adopt to hang weight, adjusts haulage cable by the gravity tensioning tension wheel.Weight hammer type tensioning mode has following shortcoming:
1, service life of steel wire rope is short, and consumption is large, changes frequently, and is large to Influence of production.
Because the well head lifting capacity is large, steel rope and rope sheave back and forth wear and tear often every day, add that operating environment is poor, steel rope and rope sheave are easy to wearing and tearing, and service life is short, often just need in 10～15 days to change, and at every turn more change steel rope to affect 2 hours lifting time, larger to Influence of production.
2, change the rope inconvenience, need number many.
Since weight be with steel wire hang on counter-balanced carriage, more when change steel rope and rope sheave, need 3～4 people first weight to be put down, remove counterweight, make steel wire rope looseness, change again.
3, steel rope is easily skipped rope on the rope sheave.
During car puller work, because the elastic telescopic of load variations and steel rope, easily cause the weight bob, when hanging steel rope is flexible when causing that weight is up beated, haulage cable produces and relaxes, thereby causes haulage cable pine thigh on reel, produces wrong thigh and takes off rope, even can twist on main shaft, make the steel rope major injury and scrap.
4, tensioning mode is complicated, exists safety factor many.
Weight hammer type tensioning mode often needs to make hanger bracket, and hanger bracket not only will consume steel, also will take the place, for not affecting operation, hanger bracket often is installed in apart from the place of well head certain distance, and this just needs more wheel flutter and hanging steel rope, makes system comparatively complicated.In addition, because weight is to be suspended on the frame, during replacing, careless manipulation will injure personnel by a crashing object.Sometimes also can deviate to drop from suspension hook when weight is beated, also can threaten personnel component.
In sum, the weight hammer type tensioner system is loaded down with trivial details, and inconvenient operation is dangerous, and consumption of materials is large, and is long to the Influence of production time.And that the car puller that uses the weight hammer type tensioner uses in the mine is the most general, and therefore, it is very huge with replacement weight hammer type meaning to design a kind of novel tensioning device.
The utility model content
Loaded down with trivial details in order to solve existing weight hammer type tensioner system, inconvenient operation, dangerous, consumption of materials is large, and to long technical matters of Influence of production time, the utility model provides a kind of car puller of realizing to transfer rope convenient, simple to operate, safety, reliable in action, tensile force is large, guarantees the car puller spring piston type tensioner of car puller normal operation.
In order to realize above-mentioned technical purpose, the technical solution of the utility model is, a kind of car puller spring piston type tensioner, comprise cylindrical shell, piston rod, piston, tension spring, connecting rod, fixed lug, tommy bar, bearing and tension wheel, described bearing is fixed on the ground, described cylindrical shell and fixed lug are individually fixed in the two ends of bearing, described connecting rod one end is provided be used to the connecting rod earrings that is connected and fixed earrings, the other end of connecting rod stretches in the cylindrical shell, described piston is arranged in the cylindrical shell, be connected by tension spring between described piston and connecting rod, described piston rod one end connects piston, the other end of piston rod is connected to tension wheel and can drives tension wheel and moves forward and backward to realize tightening and loosening steel rope along the tension wheel guide rail, described tommy bar comprises main tommy bar and a tommy bar, one end of described tommy bar is connected to main tommy bar by movable axis, and the other end is connected to piston rod by movable axis, and described main tommy bar is connected to cylindrical shell by movable axis.
Described a kind of car puller spring piston type tensioner, described piston rod is provided with the piston rod lifting lug, described tommy bar is provided with for a tommy bar lifting lug that mates the piston rod lifting lug, propping up tommy bar and piston rod is flexibly connected by a tommy bar lifting lug and piston rod lifting lug, described cylindrical shell is provided with the cylindrical shell lifting lug, described main tommy bar is provided with main tommy bar lifting lug, and main tommy bar and cylindrical shell are flexibly connected by main tommy bar lifting lug and cylindrical shell lifting lug.
Described a kind of car puller spring piston type tensioner, described cylindrical shell is provided with setting nut for adjustment of tonicity spring tension size at connecting rod one end, and described setting nut stretches in the cylindrical shell, and described connecting rod passes setting nut to cylindrical shell.
Technique effect of the present utility model is, when needs are changed and adjust steel wire rope tension, only need a people to install tommy bar temporarily, then by tommy bar pulling tension wheel, discharge lineoutofservice signal pull, stationary links again, just can change on the expansion tightening wheel steel rope and in restricted, the utility model is not only simple in structure, and transfers rope convenient, fast.
