Abstract

The utility model involves a double rope drums lifting machine, the vertical shaft connected with base is mounted with bearing, the bearing sleeve connected with flat plate is covered on the bearing, the boom, bearing sleeve and flat plate are connected reliably, the integrated motor, reducer and bearing seat is fixed on flat plate, one shaft end of the double rope drum is through a coupling shaft sleeve with flat key to connect with output shaft of reducer, the other end is supported by bearing seat; an upper trolley is fixed on top of boom, under it, the lower trolley is mounted on upper part of boom. One wire rope is reeled on slot of double rope drums in clockwise direction and the other wire rope is reeled on the other slot of double rope drums in anticlockwise direction, their ends are fastened on hook and reeled the upper trolley and lower trolley on boom. The utility model is with simple structure, high work efficiency, save energy, light weight, low cost, it is suitable for transport, hoisting in small ranged construction site or lifting grain on platform in countryside.

Description

Two reel loop wheel machines

Technical field the utility model relates to a kind of elevator machinery, particularly a kind of pair of reel loop wheel machine.

Background technology is present, lacks weight-lifting equipment in rural area and small building building site, builds a building or hang solarization cereal to rely on the manpower transport often, and is very heavy.

The summary of the invention the purpose of this utility model provides a kind of simple in structure, two reel loop wheel machines that work efficiency is high, in light weight, easy to use.

The utility model is realized by following technical proposal: a kind of pair of reel loop wheel machine, on the vertical shaft that the base with it is connected as a single entity, bearing is housed, and the bearing carrier ring that is connected as a single entity with flat board is sleeved on the outer ring of bearing, and arm, bearing carrier ring firmly are connected with dull and stereotyped three; Interconnected electrical motor of axle head and reductor and bearing seat are installed on the flat board, and an axle head of double flute reel is connected with the output shaft of reductor by the connecting shaft cover of band flat key, and the other end is by bearing block support; Arm is provided with the stirrup that is connected as a single entity with it, on the top of arm top sheave is housed, and is positioned under the top sheave, on the top of arm lower sheave is housed.The steel cable cw is wrapped in the groove of double flute reel, and another root steel rope conter clockwise is wrapped in another groove of double flute reel, and all fastening suspension hook in their termination and walking around is positioned at the top sheave, lower sheave of arm, dislocation up and down and descends.No matter the electrical motor forward or reverse, always the steel cable hoisting heavy is arranged, another suspension hook is transferred, and does not have idle travel, and its work efficiency is the twice of single slot reel loop wheel machine, economizes on electricity 50% simultaneously.Because top sheave and lower sheave misplace up and down, hang over two materials on the suspension hook and can not bump against.

The beneficial effects of the utility model are: two reel loop wheel machines are simple in structure, work efficiency is high, energy-conservation, in light weight, cost is low, be convenient to carrying, be suitable for the lifting of small building building site or, play the effect that alleviates heavy physical labor and improve work efficiency at the rural area roof platform solarization cereal of hanging oneself.

Description of drawings further specifies the utility model below in conjunction with drawings and Examples.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the birds-eye view of Fig. 1.

Specific embodiments embodiment is shown in Fig. 1-2: a kind of pair of reel loop wheel machine makes things convenient for loop wheel machine, on the vertical shaft (2) that the base (1) with it is connected as a single entity, bearing (3) is housed, the bearing carrier ring (4) that is connected as a single entity with dull and stereotyped (5) is sleeved on the outer ring of bearing (3), and arm (10), bearing carrier ring (4) are welded as a whole with dull and stereotyped (5) three; Interconnected electrical motor of axle head (6) and worm-gear speed reducer (8) and bearing seat (7) are installed on the flat board (5).Worm and gear has auto-lock function, and after the outage, the weight of lifting (16) can rest on height arbitrarily, can not fall, and guarantees safety.An axle head of double flute reel (9) is connected with the output shaft of reductor (8) by the connecting shaft cover of band flat key, and the other end is supported by bearing seat (7); On the arm that is welded with stirrup (15) (10) top top sheave (12) is housed, is positioned under the top sheave (12), lower sheave (13) is housed on the top of arm (10).Steel cable (11) cw is wrapped in the groove of double flute reel (9), another root steel rope (11) conter clockwise is wrapped in another groove of double flute reel (9), and all fastening suspension hook in their termination (1 4) and walking around is positioned at the top sheave (12), lower sheave (13) of arm (10), dislocation up and down and descends.No matter electrical motor (6) forward or reverse, always steel cable (11) hoisting heavy (16) is arranged, another suspension hook (14) is transferred, and does not have idle travel, so the work efficiency height.Because top sheave (12) and lower sheave (13) misplaces up and down, the material that hangs on two suspension hooks (14) can not collided, and is very big or when meeting strong wind as material, can descend extension one hauling rope at it, controlled by the ground staff.

Claims
