Description

Safety testing device for hydraulic lifting platform Technical Field The utility model belongs to the technical field of safety detection, and particularly relates to a safety testing device for a hydraulic lifting platform. Background The hydraulic lifting platform is a multifunctional lifting loading and unloading mechanical device. The hydraulic lifting platform is applied to high-altitude operation and maintenance of factories, automatic warehouses, parking lots, municipal administration, wharfs, buildings, decoration, logistics, electric power, traffic, petroleum, chemical industry, hotels, gymnasiums, industrial and mining, enterprises and the like, and is required to be subjected to safety detection after production in order to ensure the subsequent use safety of the hydraulic lifting platform. At present, the safety test mode of the hydraulic platform is generally to apply pressure to the platform, whether the platform is stably supported under different pressures is tested by changing the pressure applying force, however, the pressure applying point of the test device is fixed, the surface stress of the platform is uneven during actual use, and the platform is likely to incline or shake due to stress deflection, so that the safety detection is excessively ideal through the mode, and the subsequent safety use of the lifting platform cannot be ensured. Disclosure of utility model The utility model provides a safety testing device for a hydraulic lifting platform, and aims to solve the problems that an existing portal frame is high in installation position and inconvenient to view and assemble and disassemble. The utility model discloses a safety testing device for a hydraulic lifting platform, which comprises a portal frame, wherein an electric cylinder is arranged at the top of the portal frame through a fixing frame, a first pressure sensor is connected to the bottom of an output shaft of the electric cylinder, a fixed plate is connected to the bottom of the first pressure sensor, a sliding groove is formed in the fixed plate, a screw is arranged in the sliding groove, a motor is arranged on the side surface of the fixed plate, an output shaft of the motor is connected with the rod end of the screw, a sliding block is slidably arranged in the sliding groove of the fixed plate, a thread groove matched with the thread on the surface of the screw is formed in the surface of the sliding block, a connecting frame is connected to the bottom of the sliding block, and a pressing block is arranged on the lower side of the connecting frame.
