A performance testing device for a gantry crane

Abstract

The invention discloses a portal crane performance detection device. The portal crane performance detection device comprises a cross beam, wherein support rods are arranged on two sides of the bottomof the cross beam, a sliding trolley is arranged at the center of the bottom of each support rod, a drag hook is fixedly connected with the bottom of each sliding trolley, a fixing plate is arranged at the bottom of each drag hook, a load block is rotatably connected with the top of each fixing plate, a rotating ring is rotatably connected with the bottom of each drag hook, and a connection rod isrotatably connected with the side wall of each rotating ring. The portal crane performance detection device drives gears to rotate through motors, drives fixing cylinders to move through the gears, enables the fixing cylinders to drive the load blocks to move through support plates, changes the positions of the load blocks, can gather the load blocks to one side or arrange the load blocks in a distribution mode, rotates connection screw rods upwards so as to enable the connection screw rods to separate from the fixing cylinders, respectively forks and removes the load blocks, and has the advantages of being capable of regulating load distribution situations under different states, conveniently increasing and decreasing load, and keeping stable.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a performance detection device for gantry cranes. Background technique [0002] Most of the gantry cranes are used outdoors. They are often installed in freight yards, ports, and other places to lift and unload goods. , There are two legs carrying the main beam, and the legs are equipped with wheels, which can walk and move on the track. There are only two legs supporting the ground, so the floor space is small, the applicability is strong, and it is more versatile, and it is useful in many places. Gantry cranes are usually transported separately to the destination, and then installed. After the assembly is completed, various inspections and inspections are carried out. Only after passing the test can they pass the acceptance test. The load detection of gantry cranes is particularly important in performance testing. [0003] In the load test, multiple groups are usually carried o...
