Abstract

A kind of crane carriage without frame speed regulation, the chassis of the electrical machinery is between decelerator and tailstock, the speed regulating device, main hoisting electrical machinery, brake are on the chassis of the electrical machinery, the crown block is fitted on the main hoisting reel, both ends of the main hoisting reel are supported in decelerator and tailstock hole separately; the trolley running driving device is arranged on a box body of the speed reducer, and wheels for supporting the trolley are respectively arranged below the speed reducer and the tail frame. The stepless speed regulation of the main hoisting mechanism is realized by adopting a winding motor of a vortex brake, and the speed change of the trolley is realized by adopting an alternating current winding pole-changing motor. In addition, the structure reduces the weight and the height of the trolley, so that the height of the whole machine and a workshop is reduced.

Description

The crane carriage of no vehicle frame speed governing

The utility model relates to a kind of at chassis or dolly fixing or that movably walk on crane span structure or the door frame.

Along with developing rapidly of industry, also more and more higher to the requirement of crane in bridge type in recent years, and the crane carriage that vehicle frame is arranged that uses at present, its structure is seen Fig. 1, Fig. 2, and parts such as main lifting motor 7, retarder 2, fixed pulley group 3, main hoisting drum 4, auxiliary hoisting mechanism 5, drive car 9 are housed on vehicle frame 8; The wheel 1 of supporting carriage is housed below vehicle frame 8.Main hoisting drum 4 is bearing on the vehicle frame 8 by the bearing 6 at two ends, and main hoisting capacity major part is born by the fixed pulley group 3 that is supported on the vehicle frame 8, and fraction is born by main hoisting drum 4.This crane carriage structure heaviness, bulky, make hoisting crane from great, the factory building cost is also high, and hoists and trolley travelling has only a kind of speed, impacts greatly, and operation is not steady.

The purpose of this utility model is: be developed into a kind of crane carriage that does not have vehicle frame, so that solve existing problem in the background technology.

The technical solution adopted in the utility model is: it mainly comprises retarder, main lifting motor, fixed pulley group, main hoisting drum, auxiliary hoisting mechanism, drive car etc.As shown in Figure 3, Figure 4, motor underframe 16 is installed between retarder 10 and the tailstock 15; One end is connected with speed regulation device 18, the other end and coupler 21 bonded assembly master lifting motors 20, speed regulation device 18, drg 22 are installed on the motor underframe 16; Fixed pulley group 17 is enclosed within have been led on the reel 11, and the two ends of main hoisting drum 11 are bearing in respectively in retarder 10 and tailstock 15 holes, and speed regulation device 18 adopts the coiling electric motor of eddy-current brake; Drive car 19 is installed on the casing of retarder 10; The wheel 12 of supporting carriage is installed in respectively below retarder 10 and the tailstock 15, and auxiliary hoisting mechanism 14 is installed on the subframe 23, is connected with tailstock 15 with retarder 10 respectively with hinge 13.

The utility model is compared the useful effect that is had with background technology:

1) structure of the crane carriage of the no vehicle frame speed governing of employing can make crane carriage weight reduction 40%, highly reduces more than 40%, the hoisting crane deadweight is reduced, and then the cart wheel load is reduced, the complete machine height reduces, make the corresponding reduction of factory building height, thereby save the factory building investment;

2) owing to adopt the eddy-current brake speed governing, make the drum speed of main hoisting mechanism can carry out infinite speed variation in 1/15～1 speed range, carriage walking speed can make whole crane carriage easy to operate in command speed and the operation of 1/4 speed.Be applicable to handling, the installation of valuable or precise article, even also use steadily than the hoisting crane of single speed in general occasion.

Below the utility model will be further described.

Fig. 1, the crane carriage front view of vehicle frame is arranged;

Fig. 2, the crane carriage birds-eye view of vehicle frame is arranged;

Fig. 3, front view of the present utility model;

Fig. 4.Birds-eye view of the present utility model.

As shown in Figure 3, Figure 4, the working process of main hoisting mechanism is: the main actuating motor 20 after speed regulation device 18 speed governing, drive the first order gear input of retarder by coupler 21, by final stage gear outputting power, gear driven one end is loaded on its endoporus, and the main hoisting drum 11 that the other end is loaded in tailstock 15 holes rotates, on the main hoisting drum 11 fixed pulley group 17 is housed, reel 11 volumes are put steel rope, make the weight lifting on the suspension hook, and main hoisting drum bears whole hoisting capacities.Drg 22 is housed on the coupler 21.Speed regulation device 18 can adopt the interchange coiling electric motor of VZ eddy-current brake or the eddy-current brake of YZRW band, realizes the main hoisting mechanism infinite speed variation.Trolley travelling actuating device 19 adopts three-in-one retarder, be installed on the casing of retarder 10 fixing, its two mouth respectively be contained in retarder 10 and be connected with wheel 12 below tailstock 15 1 ends, adopt to exchange coiling pole-changing motor realization crane carriage speed change, make crane carriage follow the Car Track motion.Auxiliary hoisting mechanism 14 is installed on the subframe 23, is connected with tailstock 15 with retarder 10 respectively by hinge 13, equally also is to drive secondary hoisting drum by self motor by retarder, and volume is put steel rope, makes the weight lifting on the suspension hook.
