The utility model has the structure that the utility model is provided with a frame-shaped supporting bracket provided with a movable cross beam and a pulley block, wherein, a movable pulley of which is connected with the movable cross beam and a fixed pulley is fixed on the upper end of the supporting bracket; the movable cross beam is provided with a central hole assembled with a central shaft. The head end of a wire rope of the pulley block is connected with a hub of a reducer output shaft; both ends of the movable cross beam are provided with movable brackets provided with rollers. A bottom bracket of the frame-shaped supporting bracket is provided with the roller and a supporting disc.
Description
What the utility model elevator turning device related to is a kind of masts type, sleeve-type, double-cylinder type elevator (high-altitude operation platform) upset facility of being applicable to.
But elevator folding when off working state becomes rectangular volume, but elevator folding size is generally all taller and bigger, and it is high that the size when it is stood is above standard, and limited the equipment range of use.Particularly double-mast formula elevator folding size is taller and bigger, and especially contradiction is particularly outstanding when the entrance hall of turnover corridor, and the door for lower can't pass in and out, and can only be placed on outdoor use.Particularly upstairs layer uses carrying extremely inconvenient.
The purpose of this utility model is to provide a kind of elevator turning device at above-mentioned weak point, have frame shape bearing support, center shaft, elevator can be clamped in turning device and raise bulk wight heart height, make the elevator rotation, become lower size from the original higher size of standing, can make things convenient for the problem that passes in and out various gateways thereby solved elevator smoothly by relatively low standard gateway or passage.
The elevator turning device takes following scheme to realize: elevator turning device structure has the frame shape bearing support, one removable crossbeam and assembly pulley arranged on the frame shape bearing support, the movable pulley of assembly pulley connects with moving beam, fixed pulley is fixed on the bearing support upper end, the head end of steel wire rope of assembly pulley connects with the reducer output shaft wheel hub, and reducer input shaft is connected with handwheel (handle) or electrical motor.Central shaft hole is arranged on the moving beam, and device has center shaft, and there is movable stand at the moving beam two ends, and device has roller on the movable stand, and roller can be along frame shape support two heel post guide rail scroll-up/down.Frame shape support underframe is provided with roller, step disk, is convenient to the frame shape support and moves on ground, also can support on the ground reposefully.
During the work of elevator turning device, place elevator or other to need the rolling object center-of-gravity position anchor clamps or center shaft, the moving beam of lifting turning device is born two ends in center shaft, center shaft is gone into the center of gravity support holes of object, the shaped as frame bearing support of elevator turning device is connected with center shaft, shake the retarder handle (two people simultaneously) of both sides on the frame support or start the retarder drive motor, elevator or need rolling object slowly rise, when slightly surpassing elevator or object radius of turn, elevator or object height of gravitational center stop, by the corner of manually touching (drawing) elevator or object, elevator or object be half-twist like a cork naturally, oppositely shake the retarder handle or start the drive motor counter-rotating, elevator or object move down, keep flat ground, remove and promptly reach the requirement for height that elevator or object are crossed gateway or passage behind the shaped as frame bearing support, promote convenient various gateways of turnover of elevator or object or passage.
The elevator turning device is held the height of gravitational center of elevator or object by adjustment, changes elevator or object attitude, and then reduces the shipping height of elevator or object or recover its running condition.The application engineering one that its technology category belongs in the theory of machines is to make the axle center of object center of gravity perpendicular to wheel word, makes the object rotation with less external force; The 2nd, make the object rotation, its radius of turn must be greater than the distance of elevator center of gravity to the maximum boundary point of object; Utilize the principle of the former effort-saving mechanism of assembly pulley, weight is improved or decline,, just make elevator become lower size from the original higher size of standing by this covering device, can pass through relatively low standard gate or passage smoothly, solve the problem of the various gateways of the convenient turnover of elevator.This device is applicable to that the passage excessively of masts type, sleeve-type, double-cylinder type elevator requires and the attitude adjustment of similar object.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is an elevator turning device structural representation.
Fig. 2 is the frame shape bearing support front view of elevator turning device.
Fig. 3 is the frame shape bearing support left view of elevator turning device.
With reference to accompanying drawing, elevator turning device structure has two identical frame shape bearing supports 2, one removable crossbeam 6 and assembly pulley arranged on each frame shape bearing support 2, the movable pulley 5 of assembly pulley connects with moving beam 6, fixed pulley 3 is fixed on frame shape bearing support 2 upper ends, and steel rope 4 head ends of assembly pulley connect with the output shaft wheel hub of retarder 8, and steel rope 4 other ends are installed between one group of fixed pulley, the movable pulley, the input shaft of retarder 8 is connected with handwheel (handle) 9, also can install electrical motor.Retarder 8 can adopt the Worm-gear type retarder, and retarder 8 devices are on the fixed cross beam 17 of frame shape bearing support.On the moving beam 6 central shaft hole is arranged, device has center shaft 7 in the central shaft hole, and there is movable stand 14 at moving beam 6 two ends, and device has one group of roller 15 on the movable stand 14, and roller 15 can be along frame shape bearing support two heel post guide rails 16 scroll-up/down.Drive retarders by steel rope, drive on moving beam and the supporting center shaft 7 elevator or object moves up along the column guide rail by handwheel (handle) 9 through pulley.Elevator or object height of gravitational center stop when slightly surpassing elevator or object radius of turn 11 by manually touching (drawing) elevator or object corner, can light half-twist.Oppositely shake retarder handle 9, steel rope drives moving beam 6 and elevator or object through pulley and moves down, and keeps flat ground.The underframe 12 of frame shape support 2 is provided with several rollers 13, is convenient to the frame shape support and moves on ground.Also be provided with step disk 18 on the underframe 12 of frame shape support 2, step disk 18 is equipped with regulating handle 19, and frame shape support 2 supports on the ground reposefully when being convenient to work.
