Abstract

The invention discloses a limiting mechanism of a hoisting device. The limiting mechanism of the hoisting device comprises two side vertical plates, a rear vertical plate is arranged on the rear sidesof the two side vertical plates, a take-up wheel is arranged between the two side vertical plates, a rope is wound on the take-up wheel, a motor is arranged on the outer side of one side vertical plate, the motor is connected with the take-up wheel, a wire guide wheel is arranged on the front side of a machine body, and the two ends of the wire guide wheel are connected with the side vertical plates on the corresponding sides through supporting rods respectively; a stop wheel is arranged above the front side of the wire guide wheel, a gap is reserved between the stop wheel and the wire guidewheel, each of the two ends of the stop wheel is provided with a rocker arm extending backwards, the rear side of each rocker arm is hinged to the machine body and provided with an extending part, themachine body is provided with limiting switches corresponding to the extending parts, the movable end of the rope penetrates through the gap between the stop wheel and the wire guide wheel, a storagebattery and a controller are arranged below the rear vertical plates, and the storage battery, the motor and the limiting switches are all electrically connected with the controller. The mechanism can prevent excessive take-up in the take-up process of the hoisting device, and the safety of cargos and the hoisting device is protected.

Description

technical field [0001] The invention relates to a limit mechanism of a lifting device. Background technique [0002] When the lifting device on the insulated bucket truck lifts the goods, it is generally operated manually. Due to the poor accuracy of the manual operation, it often encounters the situation of excessive winding. After excessive winding, the goods may hit the lifting device or the motor may overheat. cause danger. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a limit mechanism of the hoisting device, which can prevent excessive wire-rewinding during the hoisting device, and protect the safety of the cargo and the hoisting device. [0004] In order to solve the above-mentioned technical problems, the present invention provides a limit mechanism of a lifting device, which includes two side vertical plates arranged opposite to each other on the left and right, and a rear vertical plate connecting th...
