Universal forklift portal test bench

Abstract

The invention discloses a universal forklift portal test bench. The universal forklift portal test bench comprises a flat plate carrying assembly capable of moving along the ground, a portal frame mounting seat used for fixing a horizontal part of a test portal frame, a vertical mounting seat used for being connected with a vertical part of the test portal frame, a portal frame inclination adjusting device used for adjusting an inclination angle needed by assembly of the vertical part, a portal frame lifting protection frame used for preventing the test portal frame from tipping over and a control device used for controlling the test portal frame to carry out corresponding experiment operation; wherein the gantry mounting base, the vertical mounting base and the control device are all arranged on the flat plate carrying assembly, one end of the gantry inclination adjusting device is connected with the vertical mounting base, the other end of the gantry inclination adjusting device is connected with a lug hole of the vertical part, the portal frame lifting protection frame is provided with a hollow part and a lifting channel so that the test gantry can pass through the hollow part to be assembled with the gantry mounting seat, and the vertical part can move along the lifting channel conveniently. According to the universal forklift portal frame test bench provided by the invention, accuracy, applicability and safety of the forklift portal frame performance test bed can be improved.

Description

technical field [0001] The invention relates to the technical field of forklift mast lifting fatigue test detection, and more specifically relates to a general-purpose forklift mast test bench. Background technique [0002] Nowadays, with the progress of society, the manufacturing industry is constantly improving, and the quality of products is also constantly improving. Following the spirit of craftsmanship, the quality, safety and reliability of industrial vehicles are also improving. Forklifts are industrial handling vehicles. The technical parameters of the forklift are used to measure the structural characteristics and working performance of the forklift. Among them, the forklift mast test mainly tests the rated lifting capacity of the forklift, the maximum lifting height, the inclination angle of the mast, the lifting pressure of the oil cylinder, and the fatigue test of the mast. [0003] However, at present, when performing performance tests on forklift masts, it is...

AI Technical Summary

Problems solved by technology

[0003] However, at present, when performing performance tests on forklift masts, it is necessary to park the test vehicle on a stable road for rated lift tests and maximum lift height tests. The test is a very dangerous test. Newly developed vehicles cannot fully guarantee the safety of the vehicle, especially when conducting ultra-high load tests, there are many uncertain factors

In addition, in the fatigue test of mast lifting and lateral movement, the long-term lifting and lowering of the mast cannot be directly completed manually.

That is to say, there is no suitable forklift mast performance test bench at this stage, and the forklift mast performance test cannot be accurately performed

[0004] Moreover, the installation state of the mast on the existing mast test bench is different from that of the actual vehicle, which easily leads to the inability to guarantee the integrity and accuracy of the test data, let alone judge whether the performance test of the mast conforms to Design requirements
