Abstract

The invention discloses a lifting platform based on a trolley for an elevator load test, which comprises a chassis and a carrying platform, and further comprises a central driving mechanism and a closed-loop lifting unit, and the closed-loop lifting unit comprises a lifting trolley, a lifting middle column and a pair of scissor arms symmetrically arranged between the chassis and the carrying platform. The scissor arms comprise a chassis scissor arm and a carrying scissor arm; a lifting middle column is further fixedly connected between the chassis scissor arm on the left side and the chassis scissor arm on the right side. The lifting trolley is arranged on the upper surface of the chassis in a front-back sliding fit mode, a pair of vertical base plates extend on the lifting trolley, vertical guide grooves are formed in the vertical base plates, and the lifting middle column is sleeved with the vertical guide grooves. And the output end of the central driving mechanism is in driving connection with the lifting trolley. The device is reasonable in structural design and flexible in movement, adopts a guide rod sliding block mechanism as a control mechanism, can achieve the stable lifting of the carrying platform, and facilitates the improvement of the detection efficiency of an elevator load test.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for elevator load tests, in particular to a lifting platform based on a trolley for elevator load tests. Background technique [0002] In daily use, elevators need to be periodically tested for load-carrying performance. The traditional test method is to carry out the test through static load tests, that is, to carry the load weights into the elevator car. The test process is cumbersome, especially the handling of the load counterweight is very labor-intensive and low. effect. [0003] The existing device has slow speed and low precision in the process of carrying heavy objects, which is extremely inconvenient. Therefore, it is necessary to design a lifting platform to enable the device to have the function of lifting heavy objects while avoiding injuries to operators. Contents of the invention [0004] The object of the present invention is to provide a lifting platform based on a...
