Problems solved by technology

[0005] Although the existing load weighing system protects the scissor lift work platform to a certain extent, there are still some shortcomings. For example, in actual work, the working height of the scissor lift work platform is often less than the maximum work height. When the working platform does not reach the maximum height during the working process, it can carr

Example Embodiment

[0018] The present invention will be further described below in conjunction with the drawings and embodiments:

[0019] Such as figure 1 As shown, a double-load weighing system for a scissor-type lifting work platform includes an angle sensor 1 that records the lifting height of the work platform and a pressure sensor 2 that records the lifting pressure of an oil cylinder. The angle sensor 1 and the pressure sensor 2 respectively pass through wires Connected to the electrical control unit 3, the electrical control unit 3 is respectively connected to the low limit switch 4 and the highest limit switch 5 through wires, and the angle sensor 1 is designed to detect the lifting height of the working platform in real time and convert the lifting height The electrical signal is transmitted to the electrical control unit 3; the pressure sensor 2 is designed to accurately detect the lifting pressure of the cylinder under the rated power in real time when the working platform carries diffe...

Abstract

Provided is a double-load weighing system for a scissor-fork-type lifting working platform. The system includes an angle sensor and a pressure sensor, the angle sensor is used for recording the lifting height of the working platform, the pressure sensor is used for recording the lifting pressure of an oil cylinder, the angle sensor and the pressure sensor are separately connected with an electric control unit throughwires, andthe electric control unit is connected with a low-position limiting switch and a highest limiting switch. The system has two rated loads, and has the advantages of being high in working efficiency, simple in structural design and low in cost.

Description

[0001] Technical field: [0002] The invention relates to the technical field of scissor lifts, in particular to a double-load weighing system for a scissor lift work platform. [0003] Background technique: [0004] The scissor lift work platform is a special equipment for high-altitude operations with a wide range of uses. The load weighing system is one of the necessary safety guarantee systems for the scissor lift work platform. At present, the load weighing system on the scissor lift work platform is usually only set A rated load, that is, the maximum load set to ensure the stability of the vehicle when the working platform reaches the maximum height. [0005] Although the existing load weighing system protects the scissor lift work platform to a certain extent, there are still some shortcomings. For example, in actual work, the working height of the scissor lift work platform is often less than the maximum work height. When the working platform does not reach the maximum...
