Problems solved by technology

However, the technical threshold of lifting platform products is low. The current lifting platform products generally have problems such as insufficient safety protection, low degree of automation, and low safety factor. The overload limit is realized by safety management. Carry equipment and tools for control so that the total load does not exceed the rated load, so as to achieve overload protection. It is completely dependent on human management intervention, and there are security loopholes; at the same time, the tilt protection of the lifting platform depends on the synchronization and performance of the equipment itself Ensure balance, once the equipment fails, it may cause the equipment to tilt and cause danger

Abstract

The invention provides a safety protection device for a lifting platform. The safety protection device comprises a plurality of paired pressure sensors, each of which is mounted on a wire rope for lifting the lifting platform to sense the pull of the wire rope when the lifting platform is elevated, inclinometers disposed at edges of the lifting platform to detect an angle of inclination of the lifting platform, and a safety protection controller connected with the pressure sensors and the inclinometers and used to obtain load data of the lifting platform according to the pull data of the wire ropes from the pressure sensors, and in response to that any one of the load data and the angle of inclination of the lifting platform measured by the inclinometers exceeds a set range, transmit a warning signal to a buzzer and send a safety control signal to a motor controller for the lifting platform to control start and stop of a motor. The pressure sensors are pressuremeter type pressure sensors. The safety protection device provided by the present invention is capable of warning in case of overload, eccentric load and inclination of the platform, thereby improving the use safety of the lifting platform.

Description

technical field [0001] The invention relates to the technical field of lifting platforms, in particular to a safety protection device for lifting platforms. Background technique [0002] Lifting platform products are simple in structure and easy to use, and have been widely used in many industrial fields. However, the technical threshold of lifting platform products is low. The current lifting platform products generally have problems such as insufficient safety protection, low degree of automation, and low safety factor. The overload limit is realized by safety management. Carry equipment and tools for control so that the total load does not exceed the rated load, so as to achieve overload protection. It is completely dependent on human management intervention, and there are security loopholes; at the same time, the tilt protection of the lifting platform depends on the synchronization and performance of the equipment itself Ensure the balance. Once the equipment fails, it...
