Chain hoist hook stabilization system and hoisting equipment

Abstract

The present invention relates to the technical field of hoisting equipment, and provides a hook stabilization system for an endless chain winch, including: a hook, a horizontal beam, an endless chain, a sprocket, a motor, an inclination sensor and a controller, and the sprocket includes two, The two sprockets are respectively rotatably mounted on both ends of the horizontal beam, and at the same time cooperate with the chain, the motor is installed on the horizontal beam, and the rotation shaft of the motor is connected to any one of the horizontal beams. The sprocket is matched to drive the sprocket to rotate, the inclination sensor is installed on the horizontal plane on the horizontal beam, and the hook is installed in the middle of the horizontal beam and is arranged vertically to the horizontal beam. The hook stabilization system of the chain hoist of the present invention is provided with an inclination sensor on the horizontal beam, so that the inclination sensor can measure the angle of the hook in real time, and by setting a motor and a controller, the motor drives the chain to move relative to the horizontal beam, so that the hoist Keep the hook vertical to prevent the hook from tilting.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to a hook stabilization system of an endless chain winch and hoisting equipment. Background technique [0002] The hoist is a light and small lifting device that uses a drum to wind a wire rope or a chain to lift or pull heavy objects. The hoist can lift heavy objects vertically, horizontally or obliquely. The hoist is widely used in construction, water conservancy projects, forestry, mines, wharves and other fields because of its simple operation, large amount of winding rope, and convenient displacement. [0003] For hoisting equipment including a plurality of winches, if the plurality of hoists are not synchronized, it is easy to cause the hook to tilt, and the tilt of the hook will cause heavy objects to fall off, resulting in a safety accident. In order to synchronize the multiple winches of the winch equipment, the following strict restrictions have to be imposed ...

Problems solved by technology

[0003] For hoisting equipment including multiple hoists, if the multiple hoists are not synchronized, it is easy to cause the hook to tilt, and the tilt of the hook will cause heavy objects to fall off, resulting in safety accidents

In order to synchronize the multiple winches of the winch equipment, the following strict restrictions have to be imposed on the winch equipment: a. The multiple winches are identical to each other, for example, the reduction ratios and drum sizes of the multiple winches are identical to each other; b. The installation positions of multiple hoists must be close to each other, roughly at the same position, which will lead to inconvenient arrangement of multiple hoists; c. The diameter difference of the wire ropes of multiple hoists must be controlled within a small range, generally requiring the same batch d. The multiplier of the wire ropes of multiple hoists must be the same as each other; e. The control accuracy of the length of the wire rope released and retracted by the hoist is relatively high

[0004] However, in actual operation, especially during the lifting or lowering of heavy objects, it is impossible to guarantee that the hook is in a horizontal state in real time
