Embodiment Construction

[0008] As shown in Fig. 1 and Fig. 2, a rectangular connecting plate 1 is processed to be installed on a gantry crane. Two fixing lugs 17 are welded on the connecting plate 1, and two splints 2 are fixed with bolts through the fixing lugs 17. The upper part and the lower part of the splint 2 pass through a connecting shaft 4 and 10 respectively, and the connecting shafts 4 and 10 protrude from one side of the splint 2 . The position between the extended part of the connecting shaft 4 and the splint 2 is fixed with a key to the upper rotating fork 6 and 15, and a hydraulic jack 16 is connected between the rotating fork 15 and the communicating shaft 10; leg7. A long oblique hole 9 is arranged on the swing leg 7, and a fixed shaft 8 is worn on the long oblique hole 9 and two splints 2 . Connect a blocking boot 13 with a shaft 12 at the foot of the swing leg 7 . The shape of blocking shoe 13 is as shown in Figure 1, and it is that a material (as rubber) is made with the large ...

Abstract

The blocking device of gantry crane includes one connecting board with two welded ears, two clamping plates connected to the connecting board via the ears, one feed-through shaft stretched beyond the clamping plates, two rotary forks, one upper hydraulic ram connected to one of the rotary forks, one swinging leg connected to the other rotary fork, one fixed shaft penetrating through the swinging leg to the clamping plates, and blocking shoes in the shape fitting the track and the track wheel and connected via a shaft to the swinging leg. During use, the connecting board is fixed in the front of the track wheel, the blocking shoes are stretched below the track wheel and the rotary fork is rotated with the hydraulic ram, so that the swinging leg is lifted off the track and the track wheel for normal running while avoid wind driven sliding.

Description

technical field [0001] The invention belongs to a gantry type hoisting machine (gantry crane), in particular to a stopper of a gantry crane. Background technique [0002] Traditional gantry cranes only have brakes and no blockers. When encountering strong winds, they are easily blown by the wind and slide along the track at high speed, causing them to run off the track or fall over. Need a kind of stopper to stop the slide of gantry crane very much. Contents of the invention [0003] The object of the present invention is to provide a stopper installed on the gantry crane to solve the problem that the gantry crane is easy to derail and slide when encountering strong wind. [0004] The technical solution is: weld two fixing lugs on a connecting plate, fix the two splints with bolts through the fixing lugs, the upper and lower parts of the two splints pass through a connecting shaft respectively, and the connecting shaft extends out of the splint, and the upper connecting ...
