Abstract
The invention relates to a hoisting power assisting device. The device comprises a hoisting machine and a power-assisted oil cylinder, wherein a steel wire rope outlet end of the hoisting machine is hinged with a cylinder rod end of the power-assisted oil cylinder; and the end of the hoisting machine, which is far away from the steel wire rope outlet end, and the other end of the power-assisted oil cylinder, are hinged to a machine body respectively. The hoisting machine rotates a certain angle around a hinged shaft fixed in a hinged support of the machine body towards the ground by contracting the power-assisted oil cylinder, so that the aim of increasing hoisting lifting power can be fulfilled, a working device can obtain the required operation lifting power periodically, the operation stability of the whole machine is ensured, and the device has a simple structure, reliable performance and operation safety.
Description
Technical field
The present invention relates to a kind of winding plant, particularly relate to a kind of elevator work-saving device.
Background technology
In the occasion that hoisting force need be provided by elevator; the at present employing directly is connected elevator on the main frame fuselage by fastener more; and control elevator and roll to drive the steel rope that detours on elevator and realize its enhanced feature; when the equipment that is raised when certain stage of lift stroke need be greater than the hoisting force of normal value; promptly need short range that hoisting force greater than normal value is provided; and all the other make stroke and only need than the farm labourer can move under the state of normal pulsation-free hoisting force; this load that produces in the forced stroke stage greater than normal hoisting force; can make complete machine can't provide above the hoisting force operation of normal value and suspend or discontinuous, influence smooth construction because of the short time.
Summary of the invention
Technical matters to be solved by this invention provides a kind of elevator work-saving device, solves existing winch and exists and can not provide problem greater than normal hoisting force in short range.
For solving the problems of the technologies described above, elevator work-saving device of the present invention comprises: winch, power-assisted oil cylinder, and the cylinder rod end of winch steel rope exit end and power-assisted oil cylinder is hinged, and winch is hinged on the fuselage respectively away from the other end of steel rope exit end and power-assisted oil cylinder.
According to an embodiment, described power-assisted oil cylinder is two, and the cylinder rod end of two power-assisted oil cylinders is articulated in the both sides of winch steel rope exit end respectively, and the other end of power-assisted oil cylinder is hinged on the fuselage respectively.
In the working process, when control electrohydraulic system drive reel, when the coiling rope is finished traction work, when the operation device when certain stage of its forced stroke need be greater than the hoisting force of normal value, power-assisted oil cylinder cylinder bar shrinks, the hinge of elevator in the free bearing that is fixed in fuselage rotated to an angle towards the ground direction, and give the oil cylinder pulling force, reach the purpose that increases the elevator hoisting force.
The beneficial effect that the present invention brings: can alleviate elevator and promote in the load process, run into when certain stage of its forced stroke need be greater than the hoisting force of normal value, guarantee that equipment can interimly obtain required operation hoisting force, stationarity when guaranteeing the complete machine operation, help reducing the generating capacity of hoisting equipment, cut down the consumption of energy, and simple in structure, dependable performance, job safety.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing,
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Elevator work-saving device as shown in Figure 1, the free bearing 3 that is positioned at winch 4 steel ropes 5 exit end is hinged with the cylinder rod end of power-assisted oil cylinder 1 by hinge 2, be positioned at winch 4 and be hinged on the fuselage 7 by hinge away from the free bearing 6 of steel rope 5 exit end, the cylinder body end of power-assisted oil cylinder 1 is hinged by free bearing 8 and supporting hinge and fuselage 7.
When equipment needs hoisting force, controlling electrohydraulic system makes elevator 4 running and applies hoisting force by steel rope 5 and give equipment, when equipment when certain stage of lift stroke need be greater than the hoisting force of normal value, promptly need the hoisting force of short range acceptance greater than normal value, and all the other are made stroke than the farm labourer and only need normal hoisting force can smooth running the time, power-assisted oil cylinder 1 contraction this moment, elevator 4 is rotated to an angle around free bearing 6, and apply pulling force simultaneously to increase the hoisting force of elevator 4, equipment is raised smoothly, when equipment was in the release hoisting force or need not the process of hoisting force, the cylinder bar of power-assisted oil cylinder 1 was in elongation state.
The above is the preferred embodiments of the present invention only, and does not limit the present invention in any way, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (2)
1. an elevator work-saving device is characterized in that, comprising: winch, power-assisted oil cylinder, and the cylinder rod end of winch steel rope exit end and power-assisted oil cylinder is hinged, and winch is hinged on the fuselage respectively away from the other end of steel rope exit end and power-assisted oil cylinder.
2. elevator work-saving device according to claim 1 is characterized in that: described power-assisted oil cylinder is two, and the cylinder rod end of power-assisted oil cylinder is articulated in the both sides of winch steel rope exit end respectively.
