Abstract
The utility model relates to a lifting device which is characterized in that a winding drum is supported by a splint-shaped bracket, the upper part of the bracket is connected with one end of a wire rope of the winding drum via the guide of a free pulley of an upper hanging hook, the lower part of the bracket is directly hinged with a lower hanging hook, a shaft of the winding drum is axially connected with a multiple screw thread shaft, and a double-direction positive gear is externally sheathed. The outer part of the double-direction positive gear is sheathed with a handle and a double action card, a ratchet and a ratchet pawl are arranged between the winding drum and the multiple screw thread shaft, and the outer end of the multiple screw thread shaft is provided with a stop nut. The utility model has two functions of lifting and tensioning, and can realize the slow operations of elevating and loosening. The utility model has the advantages of compact structure and convenient carrying. The utility model is suitable to various occasions such as the occasions of building installation, mechanical repair, goods binding, cable erection, etc.
Description
The utility model belongs to the mobile lift device, the hand power tool of particularly a kind of liftable weight and tensioning rope.
At present, comparatively light hand hoisting instrument common on market is a chain block, by himself constructional feature, make its volume big,, add and select for use the heavy chain of leading to load power transmission from great, make and move, install effort inconvenience, the lifting article are slow, and the operator does not like to use.In addition, in the operation field of tension rope, all more coarse, simple and crude as the binding of automobile goods, install electric wiring cable or the interim tensioning etc. of rope is used when erectting electric pole tight rope instrument, adopt the single-acting gear on its structure, can only do unidirectional tension, can't unload power gradually reposefully when loosening, can not be applied on arbitrarily the rising and falling of weight.
The purpose of this utility model is, the functional characteristics requirement of comprehensively rising and falling and straining two aspects, adopt double acting gear, click and bull (or T type) threaded shaft, by operating handle steel rope is twined or steadily expansion gradually on threaded shaft, so that be connected in steel rope two to the load-bearing suspension hook relatively move, thereby realize the degree of tightness and the lifting of article.
Lifter of the present utility model is made up of reel, suspension hook, transmission system, brake system, it is characterized in that, reel is by the clamping plate type bracket supports, and support top is connected with roller steel wire rope one end by the movable pulley guiding of hook, suspension hook under the support bottom directly is hinged; Drum shaft is to being connected with the bigger multiple screw thread axle of helical pitch, and the nut outer rim is two-way spur gear, and two-way spur gear overcoat catcher handle and double acting card constitute transmission system; Be provided with ratchet between the bigger multiple screw thread axle of reel and helical pitch, clamping plate type support lower end is provided with the ratchet with the ratchet coupling, and the multiple screw thread axle outer end bigger in helical pitch is provided with stop nut, constitutes brake system.
Using method of the present utility model and principle of work are, hang whole lifter with hook, following suspension hook is hung weight, depress an end of the double acting card on the handle, clockwise rotate handle, stir two-way spur gear and compress ratchet, drive the bigger multiple screw thread axle rotation of helical pitch, steel rope is wrapped on the reel, two suspension hooks are relatively moved, finish step lifting; Operating angle of left-hand revolution handle repeats above-mentioned steps more then, has just realized the lifting of weight.When the left-hand revolution handle, rely on ratchet to withstand ratchet and stop the bigger multiple screw thread axle backward rotation of helical pitch, thereby lock this mechanism weight is glided.
When falling weight, adjust the other end of depressing the double acting card earlier; Rotate counterclockwise handle, handle will be stirred two-way spur gear and can rotate and be close to stop nut, drive the bigger multiple screw thread axle contrarotation of helical pitch and launch steel rope on the reel, and the step of finishing weight descends.At this moment, the multiple screw thread axle that helical pitch is bigger is to be driven by two-way spur gear to do opposite spin, because employing is the bigger multiple screw thread axle of helical pitch, will relatively rotate with two-way spur gear, make two-way spur gear be close to dead admittedly ratchet, lock this mechanism weight is glided.
The utility model has the advantages that, adopt double acting spur gear and bigger bull (or T type) the screw thread fit body of helical pitch, can realize the edging up of weight, gradually fall, gradually tightly, the gradually quiet run of pine, a tractor serves several purposes; Adopt the defeated power of handle, steel rope twines rolled configuration, and is easy and simple to handle, flexible and laborsaving; Compact overall structure, volume is little, and is in light weight, is easy to carry, and is convenient to install, aesthetic in appearance, of many uses.Be applicable to the station of the various weights that need to lift by crane, land such as building and installation, machine manufacture, maintenance, and colligation, the occasion of tensioning rope when setting up cable, electric wire of goods during vehicular transport.
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the constructional drawing of lifter
As seen from the figure, lifter of the present utility model is made up of reel, suspension hook, transmission system, brake system, it is characterized in that reel 1 is by the clamping plate type bracket supports, support 2 tops are by movable pulley 4 guiding of hook 3, be connected suspension hook 5 under the support bottom directly is hinged with roller steel wire rope one end; Drum shaft is to being connected with the bigger multiple screw thread axle 6 of helical pitch, and the nut outer rim is two-way spur gear 7, and two-way spur gear overcoat catcher handle 8 and double acting card 9 constitute transmission system; Be provided with ratchet 10 between the bigger multiple screw thread axle of reel and helical pitch, clamping plate type support lower end is provided with the ratchet 11 with the ratchet coupling, and the multiple screw thread axle outer end bigger in helical pitch is provided with stop nut 12, constitutes brake system.
