Abstract
The invention relates to a hoist which is simple in structure, efficient and convenient to install, maintain and repair, and capable of saving building area and being suitable for the long hanging distances. The hoist comprises a left pulley and a right pulley, wherein the left pulley and the right pulley are arranged at the left end of the hoist and the right end of the hoist respectively. Gates are arranged below the left pulley and the right pulley. A winding drum and a rotation driving device for the winding drum are arranged between the left pulley and the right pulley. The plane where the gates are located is perpendicular to the central axis of the winding drum. Two steel cables which are in the same direction are wound on the winding drum and connected with the gates after being led from the winding drum and wound around the left pulley and the right pulley respectively. Only one winding drum is adopted, the steel cables are used for replacing a middle synchronous shaft, and therefore the structure is greatly simplified, and manufacturing cost and building area are reduced; meanwhile, the hoist is convenient to install and maintain, can be suitable for gates with large widths, and can be suitable for the long hanging distances.
Description
Technical field

Background technology
Rolling open and close machine is to drive reel, coiling rope to complete the device of traction work by manpower or mechanical power, it can vertical-lift, level or inclination are dragged and drawn weight, existing generally take motor-driven rolling open and close machine as main, rolling open and close machine have can adapt to certain lifting altitude, handling load large, can adapt to the features such as frequently keying, can be used for the situation such as opening and closing, lifting mobile weight of gate.
The gate of growing for some width need to adopt and can adapt to grow the headstock gear that hangs distance, generally realize the ascending, descending action of the gate to the type by being symmetrical arranged two derricking gears, if adopt two derricking gears, need to synchronizing shaft be set to guarantee the synchronized operation of two suspension centres between the two at it, make the ascending, descending action of gate synchronous reliable, but adopt the design of this kind of scheme, not only need to increase synchronizing shaft and supporting parts thereof, the civil engineering area simultaneously occupying is also larger, comparatively inconvenience of installation and maintenance and maintenance.
Summary of the invention
The technical problem to be solved in the present invention is: propose a kind of simple in structure, installation and maintenance and maintenance is efficiently convenient, save civil engineering area and can adapt to the long headstock gear that hangs distance.
The technical solution adopted in the present invention is: long hanging apart from headstock gear, there is left chain wheel and right pulley that left and right two ends arrange respectively, below described left chain wheel and right pulley, be provided with gate, between described left chain wheel and right pulley, be provided with the rotating driving device of reel and reel, and the described plane at gate place and the central axis of reel are mutually vertical, on described reel, be provided with two consistent wireropes of winding direction, two described wireropes are guided into respectively and are walked around left chain wheel and be connected with gate after right pulley from reel.
Further, as a kind of concrete lifting form, left chain wheel described in the present invention and right pulley are all provided with one to be had the movable pulley of suspension hook and forms two assembly pulleys, and described wirerope is drawn from the two ends of reel and realized the ascending, descending action to gate by two assembly pulleys respectively.
Further, as a kind of form of concrete rotating driving device, rotating driving device described in the present invention has base, the reductor that drive motor is installed on described base and is connected with the output shaft of drive motor, the output shaft of described reductor is connected by gear pair with reel.
Further, as a kind of form of concrete rotating driving device, rotating driving device described in the present invention has reductor and the drive motor at the two ends that are separately positioned on reel, the output shaft of described drive motor is connected with the input shaft of reductor coupler in the hollow cavity of reel, the output shaft of described reductor is connected with reel key, and described reel, left chain wheel and right pulley are all arranged on same crossbeam.
The invention has the beneficial effects as follows: the present invention is by directly adopting the design of a reel, synchronizing shaft in the middle of replacing by wirerope, not only greatly simplify structure, the cost of manufacture and the area of civil engineering are reduced, install simultaneously and keep in repair also more for convenience, can adapt to compared with the gate of length and width degree, what can adapt to grow hangs distance.
