Abstract
The utility model relates to a rope guiding device, which is improved actively on the base of the existing traditional chain block, a hand plate rock is adopted, and a short chain drives an R type wheel which is on a crankshaft is installed on one side framework to draw a steel cable to realize lifting or arbitrarily drawing weight. The utility model has compact structure and low cost, and the utility model solves the defects that torsion has easy occurrence and the tradition chain block is inconvenient for drawing in horizontal direction when in the operation of the tradition chain block.
Description
The utility model relates to and a kind ofly is used to promote or the guide rope device of tractive weight.
At present, jack (claiming chain block again) is widely used in and promotes or the tractive weight, comprises occasion such as upright lines bar or traction electric wire in the power engineering.It is the many threads groove of coarse-pitch by an end mainly, and the other end has the transmission shaft of star gear and anti-from falling the wheel of groove and driving that friction lining is formed and anti-from focusing device with the drive wheel (pulling sprocket wheel) of the many screws thread fit of coarse-pitch, band.With with the secondary star gear change of gear matched (removing speed) device, connect fixing the composition through the support of band hook, the afterbody of star change gear transmission drives a load-bearing sprocket wheel that is placed on the turning cylinder, by chain promote, the tractive weight.Owing to pull chain and the load-bearing chain is longer, not only make this device price height, and chain reverses easily, make complicated operation, when the tractive, this shortcoming is more outstanding especially for level.
The purpose of this utility model design provides a kind of existing above-mentioned defective of traditional jack that overcomes, and cost is low, use guide rope device more easily.
The utility model is achieved in that the support at the band hook of traditional jack is provided with two frames of fixed support axle; Cover has a rotating one side with the R type rope sheave of sprocket on the back shaft; The load-bearing sprocket wheel that the afterbody of star speed change gear drives changes sprocket into and the sprocket on driving chain and R type rope sheave connects; Manually more convenient the former chain-drive drive sprocket that pulls is removed chain and loads onto crank and drive for making; The upper lay winding wire ropes of R type wheel is used for the load-bearing tractive
Chain drive and the chain load-bearing traction that pulls that the utility model changes former traditional jack is driven by shaking and steel rope load-bearing tractive, has removed original two long special chain, and the cost of reduction has solved weight and rotated the defective that causes chain to reverse.
Accompanying drawing 1, guide rope device (office is cutd open) scheme drawing.
Accompanying drawing 2, scheme drawing is looked on a guide rope device left side.
Accompanying drawing 3, scheme drawing is looked on the guide rope device right side.
Describe concrete structure of the present utility model and use in detail below in conjunction with accompanying drawing.
The utility model comprises by the driving wheel 1 on the transmission shaft 3 in the existing jack, anti-from focusing device (box), 2, in star gear change (reduction of speed) device (box) 6 and the star change gear transmission 6 the afterbody gear driven be placed in load-bearing wheel 7 on the transmission shaft 3 and band hook 5 be used for connect fixing anti-from the focusing device box) 2 form with the support 4 of star change gear transmission 6.Each commissural flange framework 10,15 of support 4 both sides, between the frame 10,15 arbor 12 is housed, be with the R type rope sheave 14 of a rotating side band chain gear 13 on it, wheel 7 is that sprocket gear and the sprocket gear of passing through driving chain 11 and R type rope sheave 14 1 sides 13 connect transmissions; Drive on the wheel 1 crank of being made up of rocking arm 8 and handle 9 is housed; Easy to loading and unloading for steel rope 19 is twined on R type rope sheave 14, frame 15 and support 4 connects for hinge, and porose 18 are placed in arbor 12 terminations on the frame 15, and the bayonet lock 17 that 18 upsides useful spring 16 in hole heads on blocks arbor 12 terminations, with fixing arbor 12.
When using the utility model, steel rope 19 1 ends can be fixed on the R type wheel 14, also steel rope 19 be fixed on bear's end on the other receipts cheese after above winding with one circuit on the R type wheel 14 again; Link up with 5 stationary positioned, the other end of steel rope 19 connects need be carried out or the tractive thing, shakes handle 9 and can shrink steel rope 19 to realize the lifting or the tractive of object by R type wheel 14.When needs put down the lifting thing or tractive thing when loosening, oppositely shake handle 9 and get final product.Under the weight effect, will make this device occur falling certainly when stopping lifting or tractive, this point is the same with traditional jack, from focusing device 2, wherein band is anti-from falling the wheel of groove by anti-, blocks from falling top flat with anti-, with friction lining and the tight stall of box wall pressure, and device is stopped from falling.
Claims (3)
1, a kind of guide rope device, by the transmission shaft in traditional jack 3 and on driving wheel 1, anti-from focusing device 2, star change gear transmission 6, and in the star change gear transmission 6 the afterbody gear driven be placed in load-bearing wheel 7 on the transmission shaft 3 and band hook 5 be used to hang the location and connect fixing anti-ly form from the focusing device 2 and the support 4 of star change gear transmission 6, it is characterized in that load-bearing wheel 7 connects transmissions for chain pitch wheel and by driving chain 11 and chain pitch wheel 13 on rotating R type rope sheave 14 1 sides that are placed on the arbor 12, be wound with steel rope 19 on the R type rope sheave 14, arbor 12 is contained in the frame 10 that is bound up on the support both sides, between 15.
2, guide rope device as claimed in claim 1, the connection that it is characterized in that described frame 15 1 ends and support 4 connects for hinge, one hole 18 that can be enclosed within arbor 12 terminations is arranged on the other end, also has a bayonet lock 17 that heads on by spring 16 on the frame of hole 18 upsides, to block the termination in arbor 12 patchholes 18.
3, guide rope device as claimed in claim 1 or 2 is characterized in that driving and is equipped with on the wheel 1 by shaking the crank that wall 8 and handle 9 are formed.
