The utility model can hang large, middle and small sized tonnage hydraulic latches or bar shaped weight, which is simple in structure, convenient in hanging point adjustment and fast in movement and assembly.
Description
Technical field:
The utility model relates to lifting, particularly a kind ofly can be used for the water conservancy gate opening/closing, can be used for the double-hanging point headstock gear that use in strip weight lift work places such as bridge, electric power, industrial and mining enterprises again.
Background technology:
The existing double-hanging point headstock gear that is used to promote water conservancy gate and other strip weight lift work, its structure is to be fixed on the cape with winch, the pulley mechanism and the suspension hook that drive on two suspension centres synchronously by the gear change transmission promote operation to the water conservancy gate opening/closing with to rectangular weight, its structure more complicated, the suspension centre adjustment is very inconvenient, because of period of service is strong, install and move all inconvenient in addition.Present electric block all is mounted on the aerial sport car, can only promote operation with a suspension centre, is not applied in two suspension centre operation places.
Summary of the invention:
The purpose of this utility model provides a kind of simple in structure, easy to adjust, the mobile and double-hanging point headstock gear quick for installation of suspension centre.
The technical solution of the utility model is finished as follows, it includes electric block, it is characterized in that: have two electric block mouths to be installed in relatively on the horizontal boatswain chair, connect a main driving axle with coupler is common respectively on the retarder high speed shaft of each mouth, have at least a support to hang bearing on sustained height on the main driving axle.Structure of the present utility model also can be installed on the horizontal boatswain chair with the reel cover of an electric block and a band retarder, connect a main driving axle jointly with coupler respectively on the high speed shaft of each retarder, have at least a support to hang bearing on boatswain chair on the main driving axle, the suspension hook on the two winding drum is hung on sustained height with lifting rope and pulley mechanism respectively.Structure of the present utility model also can be formed with an electric block and a reel cover, this electric block adopts a kind of electrical motor and retarder to be installed in the rear drive electric block of reel rear end with the coupler straight line, on the hollow shaft of reel front end, be socketed with a main driving axle, the main driving axle other end is connected with a reel cover, reel cover and electric block are all hung on boatswain chair with suspension bracket, and the suspension hook on the two winding drum is hung at sustained height through falling rope and pulley structure respectively.
Three kinds of structures of the present utility model are used for hanging the water conservancy opening/closing device or the rectangular weight of large, medium and small type tonnage respectively, have simple in structure, suspension centre is easy to adjust, moves advantage quick for installation.

The specific embodiment:
Embodiment one, as shown in Figure 1, it be a kind of be fit to open hang the double-hanging point headstock gear that large-tonnage, high-lift occasion are used, it is to hang relatively on horizontal boatswain chair 5 with two electric block mouths, connect a main driving axle 15 jointly with universal coupling 14 respectively on the high speed shaft 13 of each retarder 4, hang on boatswain chair according to hanging on the main driving axle apart from 2-4 bearings 16 is installed, the two ends of two reels 2 have bearing 1 and reel cover to be rotationally connected respectively, through pulley mechanism 10 suspension hook 11 are suspended in sustained height with lifting rope respectively between two reels 2 and the reel cover 3.During work, be used for opening and hang large tonnage water conservancy gate or other rectangular weight, its principle of work is, motor 9 electric after, the high speed shaft 13 that drives two retarders 4 by coupler 8, cucurbit transmission shaft 7, fast coupling 6 rotates, and high speed shaft drives universal coupling 14 and main driving axle 15 rotates, and the hollow shaft 12 of two retarders is rotated synchronously, rotate synchronously thereby drive two reels 2, drive two suspension hooks 11 by two pulley mechanisms 10 again and realize hoisting synchronously and landing.
Embodiment two, as shown in Figure 2, it is with an electric block and a uneasy motor and the reel and reel cover 3 straight lines that have a retarder 4 are installed on the horizontal boatswain chair 5, the high speed shaft 13 of each retarder 4 is respectively by main driving axle 15 of universal coupling 14 common connections, remaining annexation and embodiment one are identical, it mainly is applicable to the medium tonnage of lifting, the occasion of medium lift, its principle of work is: motor 9 electric after, by coupler 8, cucurbit transmission shaft 7, the rotation of the high speed shaft 13 of fast coupling 6 and retarder 4 drives its hollow shaft 12 rotates reel, meanwhile, the high speed shaft 13 that high speed shaft 13 drives universal coupling 14 and main driving axle 15 and reductor 4 rotates, rotate synchronously thereby make left hollow shaft drive left reel, and then make two pulley mechanisms 10 drive the purpose that two suspension hooks 11 are realized synchronous hoisting heavy.
Embodiment three, as shown in Figure 3, it is directly to be connected with retarder 4 by coupler 8 with a motor 9, in addition by boatswain chair 5, hollow shaft 12 main driving axle 15 of socket on the hollow shaft 12 of the outside of reel 2, the main driving axle other end is connected with a reel cover 3, according to hanging apart from installing one the bearings 16 of hanging on boatswain chair 5 need not be installed maybe on the main driving axle, remaining lifting appliance is all the same with embodiment one.Its principle of work is, motor 9 electric after, high speed shaft 13 by coupler 8, retarder 4 drives hollow shaft 12 rotations, the reel 2 that hollow shaft drives on the electric block rotates, reel drives external reel cover by main driving axle 15 and rotates synchronously, and then drives the purpose that suspension hook 11 is realized two suspension centre synchronization onwards hanging things by two cover pulley mechanisms 10.
