Abstract
The utility model relates to a gravity center adjusting mechanism of hoisting equipment, in particular to a gravity center adjusting mechanism for transversal beam type hoisting equipment, comprising a joint, a first connecting piece, a second connecting piece, two cams, a transversal beam, two side clamping plates and a lower locking piece, wherein the two ends of the two cams are respectively provided with a center hole and an eccentric hole; the center holes of the two cams coincide with each other, and are connected with the joint in serial through the first connecting piece; the two eccentric holes of the cams are connected with the side clamping plates through the second connecting piece; the center of the side clamping plate is provided with a strip hole; and the lower locking piece is arranged under the side clamping plate and is fixed on the transversal beam through being matched with the two cams. In the utility model, the hoisting component is connected to the transversal beam through the side clamping plates, the cams, a flat head shaft and a bolt, the gravity center of the device is adjusted by the cams, and the device is automatically locked. The utility model has the advantages of simple structure and convenient operation, and can adjust the gravity center of the whole device, thereby quickly realizing the requirement on hoisting for the equipment.
Description
Technical field
The utility model relates to a kind of lifting appliance center of gravity regulating mechanism, particularly a kind of center of gravity regulating mechanism that is used for the cross beam type lifting appliance.
Background technology
In general lifting appliance mainly lifts by crane center of gravity suspension placed in the middle, seldom consider the suspension that center of gravity is not placed in the middle, even if the lifting appliance of scalable center of gravity is arranged, can not regulate center of gravity in the optional position, can only regulate several fixing lifting focus points with bolt, use inconvenience, and operation is more time-consuming.
Summary of the invention
The purpose of this utility model is: provide a kind of easy to operate, have the lifting appliance of regulating lifting appliance center of gravity function.
The technical solution of the utility model is: a kind of lifting appliance center of gravity regulating mechanism, it comprises joint, first attaching parts, second attaching parts, two cams, crossbeam, two side clamping plate, following locking piece, described two cam two ends are respectively equipped with a centre hole and eccentric orfice, the centre hole of described two cams overlaps, and by first attaching parts and joint polyphone, two eccentric orfices of described cam then link to each other with the side clamping plate by second attaching parts, described side clamping plate center has can be for the strip hole that moves up and down of first attaching parts, described locking piece down is arranged on side clamping plate below, cooperates two cams to be fixed on the crossbeam.
Described first attaching parts is the tack axle, and described second attaching parts is a bolt.
The utility model beneficial effect is: the utility model lifting appliance center of gravity regulating mechanism is connected to joint on the crossbeam by side clamping plate, cam, tack axle, following locking piece and bolt, realizes automatically locking by locking piece under laced belt moving cam and the cooperation.The utility model is easy to operate, and is simple in structure, connects reliably, can adjust the center of gravity of whole device, thereby realize the lifting requirement of equipment fast, is particularly suitable for the lifting appliance of cross beam type.
Description of drawings
Fig. 1 is the structural representation of the utility model lifting appliance center of gravity regulating mechanism one better embodiment;
Fig. 2 is that a kind of lifting appliance center of gravity regulating mechanism takes down side clamp region scheme drawing;
Fig. 3 is the scheme drawing of the lifting appliance lifting suspension of adjustable apparatus center of gravity,
Wherein, 1-joint, 2-first attaching parts, 3-second attaching parts, 4-cam, 5-crossbeam, 6-side clamping plate, locking piece under the 7-.
The specific embodiment
Below by the specific embodiment the utility model is further described:
See also Fig. 1, it is the structural representation of the utility model lifting appliance center of gravity regulating mechanism one better embodiment.The utility model lifting appliance center of gravity regulating mechanism comprises joint 1, first attaching parts 2, second attaching parts 3, two cams 4, crossbeam 5, two side clamping plate 6, locking piece 7 down.In the present embodiment, described first attaching parts 2 is the tack axle, and described second attaching parts 3 is a bolt.Please consult Fig. 2 simultaneously, it is that lifting appliance center of gravity regulating mechanism takes down side clamp region scheme drawing.Described two cam 4 two ends are respectively equipped with a centre hole and eccentric orfice, and the centre hole of described two cams 4 overlaps, and by tack axle and joint 1 polyphone.Two eccentric orfices of described cam 4 then link to each other with side clamping plate 6 by bolt.There is a strip hole at described side clamping plate 6 centers, can moving up and down for the tack axle.Described locking piece 7 down is arranged on side clamping plate 6 belows, cooperates two cams 4 to be fixed on the crossbeam 5, thereby realizes the interlock of joint 1 and crossbeam 5.
See also Fig. 3, it is the scheme drawing of the lifting appliance lifting suspension of adjustable apparatus center of gravity.Before the lifting suspension,, regulate the equipment center of gravity along crossbeam 5 direction sway joints 1, hanger fitting 1, joint 1 up move, and the cam 4 that drives coupled end by the tack axle up moves, make cam 4 off-centre, thereby cooperate the locked crossbeam 5 of locking piece down, to carry out the lifting of suspension.
Therefore the utility model lifting appliance center of gravity regulating mechanism is easy to operate, simple in structure, connects reliably, can adjust the center of gravity of whole device, thereby realize the lifting requirement of equipment fast, is specially adapted to the lifting appliance of cross beam type.
