The lifting platform is installed on the lifting drive device, and the lifting drive device is arranged in the frame box. The lifting platform is driven by the lifting drive device. The fixed platform is used as a step for climbing the lifting platform; the lifting platform is provided with an instrument placement platform, and a third-party calibration device is integrated on the instrument placement platform.

As a further improvement of the present invention, the lifting drive device adopts a hydraulically driven scissor lift platform, and the lift platform is installed on the top table of the scissor lift platform.

As a further improvement of the present invention, the supporting caster assembly includes two directional casters and two swivel casters, and the two swivel casters are equipped with brakes.

As a further improvement of the present invention, a push handle is installed on the rear side of the lifting platform.

As a further improvement of the present invention, the third-party verification equipment includes an operating power supply, a cable extension board, a high-precision three-phase current and voltage meter, and a human-computer interaction system.

Compared with the prior art, the present invention has the advantages of:

(1) The structure of the present invention is simple. According to the standards of ergonomics, the operation platform and the climbing platform are combined, which reduces the labor intensity of personnel, improves work efficiency, and is conducive to clear work vision, thereby reducing the incidence of accidents.

(2) The present invention not only can be moved up and down, but also integrates third-party calibration equipment, making it more convenient for maintenance personnel to work. Secondary calibration of complete plant equipment.

(3) Through the reasonable arrangement of the working space of the test bench, the present invention effectively improves the phenomenon of irregular and irregular stacking of instruments, drawings, and materials on the work site in the past, realizes the standardization of on-site operations and 5S fixed management, and greatly improves the The work efficiency and work safety of the secondary verification work, and contribute to the refinement of on-site work.

(4) The swivel casters in the present invention are movable and lockable, which determines that the mobile test platform for secondary verification can move safely and quickly, and is convenient for overhauling several consecutive devices; at the same time, the braking performance of the swivel casters and The lockable performance ensures the stability and safety of the test platform, and provides safety guarantee for the staff working on heights.
