An overload detection device for a climbing-free device

Abstract

The invention discloses a climb-free device overload detection device. The climb-free device overload detection device comprises a steel wire rope fixing plate and an engine body fixing body, wherein two guide holes, the positions of which are overlapped, are respectively formed in the steel wire rope fixing plate and the engine body fixing body; guide pins are arranged in the guide holes and penetrate through the engine body fixing body and the steel wire rope fixing plate in sequence; a detection spring is arranged between a base of the guide pin and the engine body fixing plate; the steel wire rope fixing plate is provided with a steel wire rope fixing bolt; two ends of the steel wire rope fixing bolt are respectively connected with upper and lower joints of a climb-free device traction steel wire rope; the engine body fixing body is connected with a climb-free device engine body through a fastener; an overload detection switch is arranged on the steel wire rope fixing plate; and an overload triggering adjustment screw is arranged on the engine body fixing body. The climb-free device overload detection device is simple in structure, low in cost, convenient in mounting and debugging operations and high in safety.

Description

technical field [0001] The invention belongs to the technical field of wind power equipment, and in particular relates to an overload detection device of a climbing avoidance device. Background technique [0002] As a light-duty manned transportation device in the wind power field, the free-climbing device has a very limited load. When the actual load of the non-climbing device exceeds the rated load, it may cause safety accidents and even cause personal and property losses. Therefore, for the climbing avoidance device, the overload detection function is extremely necessary. At present, the overload of the climbing avoidance device is generally used to detect the output torque of the power device to judge the load of the equipment. However, this method is greatly affected by the resistance of the transmission system, and it is impossible to judge the load before the equipment starts, which has certain risks. If a load cell is used for detection, an external excitation power...

Problems solved by technology

At present, the overload of the climbing avoidance device is generally used to detect the output torque of the power device to judge the load of the equipment, but this method is greatly affected by the resistance of the transmission system, and it is impossible to judge the load before the equipment starts, which has certain risks.

If a load cell is used for detection, an external excitation power supply is required, and a supporting circuit is required to convert the output potential signal into a switch signal, which is more complicated to implement
