Description
Technical field
The utility model relates to crane carriage field, specifically a kind of four-point lifting crane carriage.
Background technology
Large thin-wall object must be equipped with special hanger by hoisting crane when carrying and carry out handling.Conventional crane is when handling owing to acutely rocking, and easily cause large thin-wall object to collide with and occur damaging, production efficiency is low simultaneously, there is certain potential safety hazard in use.For the problems referred to above, the utility model is for the problems referred to above, pass through brand-new design, a kind of four-point lifting crane carriage is proposed, by reasonable Arrangement and the structural design scheme of mechanism, realize four-point lifting synchronous ascending vacuum sucker lifting appliance, achieve flexible rocking-prevention function simultaneously, meet the safety carrying of large thin-wall object.
Utility model content
The purpose of this utility model is to provide a kind of four-point lifting crane carriage, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of four-point lifting crane carriage, comprise trolley frame, tetrad reel, lifting speed reducing, hoist brake, fixed pulley group, lifting motor, wheeling mechanism, rope wedge device, steel rope and vacuum sucker lifting appliance, described trolley frame is the platform structure that steel plate butt welding becomes, and its radical function is carrying lifting mechanism, operating unit; Described lifting motor is bolted mode and is arranged on trolley frame, and lifting motor is connected with lifting speed reducing input end by transmission shaft, and the mouth of described lifting speed reducing is connected with tetrad reel by drum coupling; Described hoist brake is arranged on lifting speed reducing opposite side, and hoist brake is connected with the brake axle of lifting speed reducing, described steel rope one end is fixed on trolley frame by rope wedge device, the other end is wrapped on the grooving on reel, and four fixed pulley groups of steel rope and tetrad reel both sides are in transmission connection; The below of described fixed pulley group is fixedly connected with vacuum sucker lifting appliance; By with the suspension centre of four on vacuum sucker lifting appliance with the use of, when hoisting or decline, the horizontal attitude of suspender can be guaranteed, utilizing vacuum sucker lifting appliance handling workpiece; When motor positive and inverse, slowed down by reductor, drive the rotating of tetrad reel, thus drive four wirerope-windings be wrapped on tetrad reel, formation hoists or down maneuver, and rope wedge device plays the effect of fixing steel rope, when needs are braked, be arranged on the hoist brake action on the brake axle of reductor side, realize the braking of the process that hoists; Because four steel rope winding methods are identical, one end is fixed by rope wedge device, and the other end is wound on same tetrad reel, ensure that the strict with rising with falling of four-point lifting.The four-point lifting of dolly is arranged symmetrically with relative to dolly two line of centerss simultaneously, four-point lifting pulls open larger distance, four sections of steel rope meeting unbalance stress when the vacuum sucker lifting appliance under four-point lifting waves, suspension centre can retract by stressed larger steel rope, thus the flexible anti-swing function of vacuum sucker lifting appliance under achieving four-point lifting.
Compared with prior art, the beneficial effects of the utility model are: the utility model perform hoist or down maneuver time, can effectively eliminate a lot of rise that mechanism design exists due to motor, reductor rotating speed is consistent and the nonsynchronous situation of four-point lifting that occurs, thus ensure that four suspension centres hoist decline stringent synchronization, make handling material hoist and remain horizontal attitude in decline process, therefore entirety is more stable.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 2, in the utility model embodiment, a kind of four-point lifting crane carriage, comprise trolley frame 1, tetrad reel 2, lifting speed reducing 3, hoist brake 4, fixed pulley group 5, lifting motor 6, wheeling mechanism 7, rope wedge device 8, steel rope 9 and vacuum sucker lifting appliance 10, described wheeling mechanism 7 is located on trolley frame 1, the platform structure that described trolley frame 1 becomes for steel plate butt welding, its radical function is carrying lifting mechanism, operating unit; Described lifting motor 6 is bolted mode and is arranged on trolley frame 1, and lifting motor 6 is connected with lifting speed reducing 3 input end by transmission shaft, and the mouth of described lifting speed reducing 3 is connected with tetrad reel 2 by drum coupling; Described hoist brake 4 is arranged on lifting speed reducing 3 opposite side, and hoist brake 4 is connected with the brake axle of lifting speed reducing 3, described steel rope 9 one end is fixed on trolley frame 1 by rope wedge device 8, the other end is wrapped on the grooving on reel, and steel rope 9 is in transmission connection with four fixed pulley groups 5 of tetrad reel 2 both sides; The below of described fixed pulley group 5 is fixedly connected with vacuum sucker lifting appliance 1; By with the suspension centre of four on vacuum sucker lifting appliance 10 with the use of, when hoisting or decline, the horizontal attitude of suspender 10 can be guaranteed, utilizing vacuum sucker lifting appliance handling workpiece; When lifting motor 6 rotating, slowed down by lifting speed reducing 3, drive the rotating of tetrad reel 2, thus drive four steel ropes 9 be wrapped on tetrad reel 2 to be wound around, formation hoists or down maneuver, and rope wedge device 8 plays the effect of fixing steel rope, when needs are braked, be arranged on hoist brake 4 action on the brake axle of lifting speed reducing 3 side, realize the braking of the process that hoists; Because four steel rope 9 winding methods are identical, one end is fixed by rope wedge device 8, and the other end is wound on same tetrad reel 2, ensure that the strict with rising with falling of four-point lifting.The four-point lifting of dolly is arranged symmetrically with relative to dolly two line of centerss simultaneously, four-point lifting pulls open larger distance, four sections of steel rope meeting unbalance stress when the vacuum sucker lifting appliance 10 under four-point lifting waves, suspension centre can retract by stressed larger steel rope, thus the flexible anti-swing function of vacuum sucker lifting appliance 10 under achieving four-point lifting.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
