Abstract
The utility model discloses a propelling balanced lifting device which comprises a lifting appliance main beam; a fixed blocking track is arranged in the middle of the lifting appliance main beam; the two ends of the lifting appliance main beam are respectively connected with a lifting appliance; the propelling balanced lifting device further comprises a connecting rack and a telescoping mechanism, wherein the lower end of the connecting rack is provided with a blocking groove which is matched with the blocking track; the blocking groove is used for fixing the lifting appliance main beam and the connecting rack along the longitudinal direction; the connecting rack is fixed by one end of the telescoping mechanism, and the lifting appliance main beam is fixed by the other end of the telescoping mechanism; and the blocking groove and the blocking track are driven to have transverse relative slip by the telescoping mechanism. The weights can be respectively lifted at the two ends of the propelling balanced lifting device; and the lifting appliances are not damaged even if weights at the two ends of the propelling balanced lifting device are not equal to each other in the lifting process, so that the service lives of the lifting appliances can be prolonged.
Description
Technical field
The utility model relates to a kind of promotion balance type lifting device.
Background technology
There is a kind of lifting appliance in the prior art, comprise the suspender girder, suspender girder two ends arrange respectively two groups of suspenders, weight is fixed on the suspender, then by driving tie-beam upwards with hoisting heavy, the problem that this lifting appliance exists is: owing to be placed in the suspender at suspender girder two ends all for hoisting heavy, and in the process of hoisting heavy, owing to the weight of the weight of settling on two groups of suspenders may be different, cause between tie-beam and the suspender girder mechanical force excessive, easily cause Focal drug-block, demand urgently improving.
The utility model content
For the problem that prior art exists, the purpose of this utility model is to propose a kind of promotion balance type lifting device, and its two ends all can hoisting heavy, and in the process of hoisting heavy, even two ends are not waited heavy, can not cause damage to suspender yet, thus the service life of hoisting hanger.
For reaching this purpose, the utility model by the following technical solutions:
A kind of promotion balance type lifting device comprises the suspender girder, its middle part fixed card rail, and its two ends connect respectively suspender, also comprise link span, and the link span lower end arranges draw-in groove, and draw-in groove cooperates with vertical fixed spreader girder and link span with the card rail; Telescoping mechanism, its expansion link one end captive joint frame, its other end fixed spreader girder; Driven by telescoping mechanism, horizontal relative sliding occurs with the card rail in draw-in groove.Card rail two ends arrange the anticreep plate.
Based on disclosing of above technical scheme, the utility model possesses following beneficial effect:
The utility model weight fixed spreader is not when the suspender load-bearing waits, according to lever principle, by telescoping mechanism horizontal drive link span, make two groups of suspender load-bearing balances, thereby prevent between suspender girder and the link span mechanical damage occuring, to improve service life of equipment.
Description of drawings
Fig. 1 is the integral structure scheme drawing of the utility model embodiment 1:
Wherein: 1, suspender girder; 2, telescoping mechanism; 21, expansion link; 3, link span; 4, draw-in groove; 51, suspender; 52, suspender; 6, card rail.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment:
Embodiment 1
Propose a kind of promotion balance type lifting device, comprise suspender girder 1, its middle part fixed card rail 6, its two ends connect respectively suspender 51,52, also comprise link span 3, link span 3 lower ends arrange draw-in groove 4, and draw-in groove 4 cooperates with vertical fixed spreader girder 1 and link span 3 with card rail 6; Telescoping mechanism 2, its expansion link 21 1 end captive joint framves 3, its other end fixed spreader girder 1; Driven by telescoping mechanism 2, horizontal relative sliding occurs with card rail 6 in draw-in groove 4.Card rail 6 two ends arrange anticreep plate 7.
Weight fixed spreader 51,52 is not when suspender 51,52 load-bearing wait, according to lever principle, by telescoping mechanism 2 horizontal drive link spans 3, make two groups of suspenders 51,52 load-bearing balances, thereby prevent between suspender girder 1 and the link span 3 mechanical damage occuring, to improve service life of equipment.
The above; it only is the better specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and utility model design thereof, all should be encompassed within the protection domain of the present utility model.
