Description

A kind of Double-drive electric block

Technical field

This utility model relates to a kind of electric block, specifically a kind of Double-drive electric block.

Background technology

At present, large and medium-sized enterprise's more use crane, especially smelter, owing to the production material amount of having bad luck of smelter is relatively big, crane trolley uses frequently.Existing electric block, the power set being driven between reductor and reel, are to be driven a reel and the boom hoisting such as steel wire rope and suspension hook thereof by a reductor and a motor.Have the drawback that lifting tonnage is little.Existing CD type electric block there is also that volume is big, noise big, unreasonable structure, the waste energy, lifting capacity are usually no more than 16 tons.And using the electric block of Dual-motors Driving, although lifting tonnage is improved, and for balance motor rotating speed, needs to increase synchronizer, causes its structure complicated, and cost is high.

Utility model content

The purpose of this utility model is to provide a kind of Double-drive electric block, with the problem solving to propose in above-mentioned background technology.

For achieving the above object, this utility model following technical scheme of offer: a kind of Double-drive electric block, including frame, a number reel, movable pulley, suspension hook, steel wire rope, weight sensor, No. two reels, controller, motor and reduction box module, the bottom of described frame is flexibly connected a reel and No. two reels by bearing, a number reel and No. two reels be arranged in parallel, wherein the rotating shaft of a reel and No. two reels connects corresponding motor by reduction box module respectively, the junction of a described reel and the rotating shaft of No. two reels and frame arranges weight sensor；Described weight sensor connects the input of controller, and the outfan of controller connects a reel and the motor of No. two reels respectively, the surface of a described reel and No. two reels is fixedly connected with the two ends of steel wire rope, and the middle part of steel wire rope is through the movable pulley on suspension hook.

As further program of the utility model: arranging dividing plate between a described reel and No. two reels, dividing plate is fixedly mounted in frame.

As this utility model further scheme: described controller is fixedly mounted in frame.

Compared with prior art, the beneficial effects of the utility model are: drive a reel and No. two reels respectively by two motors, play weight condition according to actual, select the duty of two motors, so that electric block has the function of high tonnage and power saving, use and more rationally facilitate.This utility structure is simple, and mode of operation is more reasonable, and lifting tonnage is high, and more power saving.

Accompanying drawing explanation

Fig. 1 is structural front view of the present utility model.

Fig. 2 is structure left view of the present utility model.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.

nullRefer to Fig. 1～2，In this utility model embodiment，A kind of Double-drive electric block，Including frame 1、A number reel 2、Dividing plate 3、Movable pulley 4、Suspension hook 5、Steel wire rope 6、Weight sensor 7、No. two reels 8、Controller 9、Motor 10、Reduction box module 11，The bottom of described frame 1 is flexibly connected a reel 2 and No. two reels 8 by bearing，A number reel 2 and No. two reels 8 be arranged in parallel，For rolling steel wire rope 6，Wherein the rotating shaft of a reel 2 and No. two reels 8 connects the motor 10 of correspondence respectively by reduction box module 11，Thus a reel 2 is operated alone and No. two reels 8 are operated，After the weight of lifting heavy reaches certain numerical value，Bi-motor is used to work to promote its lifting tonnage，And the weight of lifting heavy less than certain numerical value time，Single motor work can be used，With saves energy.

Between a described reel 2 and No. two reels 8, dividing plate 3 is set, dividing plate 3 is fixedly mounted in frame 1, prevent wirerope-winding, the junction of a described reel 2 and the rotating shaft of No. two reels 8 and frame 1 from weight sensor 7 is set, thus detects the weight of lifting by dividing plate 3；Described weight sensor 7 connects the input of controller 9, and the outfan of controller 9 connects the motor 10 of a reel 2 and No. two reels 8 respectively, thus work according to number reel of Weight control 2 of detection and the motor 10 of No. two reels 8, described controller 9 is fixedly mounted in frame 1.

The surface of a described reel 2 and No. two reels 8 is fixedly connected with the two ends of steel wire rope 6, and the middle part of steel wire rope 6 is through the movable pulley 4 on suspension hook 5.

Operation principle of the present utility model is: driven a reel 2 and No. two reels 8 respectively by two motors 10, thus play weight condition according to actual, select the duty of two motors 10, so that electric block has the function of high tonnage and power saving, use and more rationally facilitate.

It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this utility model in other specific forms.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes fallen in the implication of equivalency and scope of claim included in this utility model.Should not be considered as limiting involved claim by any reference in claim.

In addition, it is to be understood that, although this specification is been described by according to embodiment, but the most each embodiment only comprises an independent technical scheme, this narrating mode of description is only for clarity sake, description should can also be formed, through appropriately combined, other embodiments that it will be appreciated by those skilled in the art that as an entirety, the technical scheme in each embodiment by those skilled in the art.
