Abstract
The utility model discloses a cable and steel rope synchronization reel type trolley, belonging to the technical field of bridge type crane lifting mechanisms. The cable and steel rope synchronization reel type trolley comprises a trolley frame, a lifting motor, a brake, a reducer, a single reel, a trolley driving mechanism, a support and a slip ring box; one end of the single reel main shaft is connected with a low-speed shaft of the reducer, the other end of the single reel machine shaft is fixedly arranged on the support; an output shaft of the lifting motor is connected with a high-speed shaft of the reducer; the lifting motor, the brake, the reducer, the single reel, the slip ring box, the support and the trolley driving mechanism are respectively fixedly connected with the trolley frame; rope grooves used for winding a steel rope are arranged on two ends of the single reel, and a rope grove used for winding a cable is arranged in the middle of the single reel. According to the cable and steel rope synchronization reel type trolley, the cable and the steel rope are wound on the reel, thus the size of the trolley along the span direction of a cart is reduced, the weight and the energy consumption of the trolley are reduced, the synchronization of the cable and the steel rope is strictly ensured, the working efficiency of the trolley and the whole crane is increased, and the cost is lowered.
Description
Technical field
The utility model relates to the bridge crane hoisting mechanism technical field, and particularly a kind of cable and steel rope are with the roll type dolly.
Background technology
Existing crane in bridge type electric hydaulic gripping apparatus dolly is made up of lifting mechanism, wheeling mechanism and trolley frame three parts.Lifting mechanism comprises electrical motor, drg, retarder, reel and assembly pulley.Generally; Two reels are installed on the dolly at least, and a reel is used for Wound steel rope, and another reel is used for drum cable; Connect through roller chain or gear between two reels; Electrical motor drives cable drum through retarder and rotates, and makes steel rope twine reel or puts down from reel, with the up-down weight; Drive cable drum simultaneously and rotate, accomplish the extracting of gripping apparatus.
But there is following shortcoming in this crane in bridge type with dolly: 1. at least two reels of needs on the dolly will certainly increase the length of dolly along the span direction like this; 2. cable drum is connected through roller chain or gear with cable drum, is difficult to guarantee synchronism, has reduced the particularity of dolly; 3. the weight of dolly car load increases, and has increased productive costs and energy consumption, and work efficiency is lower.
Summary of the invention
In order to solve cable drum and the problems such as cable drum poor synchronization, inefficiency, productive costs height, dolly complete vehicle weight weight and energy consumption height of existing crane in bridge type with dolly; The utility model provides a kind of cable and steel rope with the roll type dolly, and said dolly comprises trolley frame, the electrical motor that hoists, drg, retarder, single drum, dolly driver train, bearing and slip ring case; One end of said single drum main shaft is connected with the slow-speed shaft of said retarder, and the other end of said single drum main shaft is fixed on the said bearing; The output shaft of the said electrical motor that hoists is connected with the high speed shaft of said retarder; The said electrical motor that hoists, drg, retarder, single drum, slip ring case, bearing and dolly driver train are captiveed joint with said trolley frame respectively; Said single drum two ends are provided with the grooving that can supply steel rope to twine, but are provided with the grooving that current supply cable twines in the middle of the said single drum.
One end of said single drum main shaft is connected with the slow-speed shaft of said retarder through coupler.
A reel only is installed on the dolly that the utility model provides, has been reduced the size of dolly greatly, reduced dolly weight and energy consumption along cart span direction; Simultaneously, cable and wire rope roll can strict be guaranteed the synchronism of cable and steel rope on a reel, improved the work efficiency of dolly and whole hoisting crane, have practiced thrift productive costs.

Fig. 2 is the cable that provides of the utility model embodiment and the steel rope front view with the roll type dolly;
Fig. 3 is steel rope and a cable position view on the single drum that provides of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model technical scheme is further described.
Referring to Fig. 1 and Fig. 2, the utility model embodiment provides a kind of cable and steel rope with the roll type dolly, and this dolly comprises: trolley frame 1, the electrical motor 2 that hoists, drg 3, retarder 4, single drum 5, dolly driver train 6, bearing 7 and slip ring case 8.Wherein, One end of single drum 5 main shafts is connected with the slow-speed shaft of retarder 4 through coupler; The other end of single drum 5 main shafts is fixed on the bearing 7, and the two ends of single drum 5 are provided with the grooving that can supply steel rope to twine, but the centre of single drum 5 is provided with the grooving that current supply cable twines; The output shaft of electrical motor 2 of hoisting is connected with the high speed shaft of retarder 4; Hoist electrical motor 2, drg 3, retarder 4 and single drum 5 is connected through bolt with trolley frame 1 respectively; Slip ring case 8 is connected through bolt with trolley frame; Bearing 7 and trolley frame 1 are connected through bolt.Dolly driver train 6 is made up of " three-in-one " driver train that wheel, transmission shaft and operation drg, operation retarder and service meter are combined into one, and passes through bolted connection on trolley frame, drives whole dolly orbiting.
Referring to Fig. 1 and Fig. 3; Install one and a single drum 5 only is installed on the dolly that the utility model embodiment provides; The electrical motor 2 that hoists drives single drum 5 through retarder 4 and rotates; Make steel rope 9 be wound on the two ends of single drum 5, steel rope 9 is put down, from the two ends of single drum with the up-down weight; Simultaneously, cable 10 is wound on the midway location of single drum 5, the mode of coiling be single laminate roll around, accomplish the extracting of gripping apparatus.
The utility model embodiment provides a kind of cable and the wire rope roll dolly on the same reel; A reel only is installed on this dolly; Being wound on two dollies on the reel respectively with cable that is adopted before and steel rope compares; This dolly has reduced to have reduced dolly and energy consumption along the size of cart span direction greatly; Simultaneously,, improved the work efficiency of dolly and whole hoisting crane, practiced thrift productive costs because cable and wire rope roll on a reel, can strict be guaranteed the synchronism of cable and steel rope.
Above-described specific embodiment; Purpose, technical scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the specific embodiment of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
