Embodiment 1

[0034] A hoisting device for a gantry crane, such as Figure 1-4As shown, it includes a reinforcing plate 1, the outer walls of both sides of the reinforcing plate 1 are fixed with elbows 9 by bolts, the outer wall of the bottom of the elbow 9 is fixed with an accommodating plate 8 by bolts, and the two accommodating plates 8 are one The side inner wall is fixed with two transverse slide bars 33 by bolts, and two slide blocks 18 are slidably connected to the circumferential outer wall of the transverse slide bar 33 , and the outer wall on one side of the slide block 18 is clamped with the outer wall on one side of the accommodation plate 8 . A spring one 17, the inner walls of the two sliders 18 are rotatably connected to a connecting rod 19, and the ends of the two connecting rods 19 away from the slider 18 are rotatably connected to the same adjustment frame 20, and the outer wall of the bottom of the adjustment frame 20 is A hoisting hook 6 is fixed by bolts, and the outer ...

Embodiment 2

[0038] A hoisting device for a gantry crane, such as Figure 1-6 As shown, in order to improve the flexibility of hoisting; this embodiment makes the following additions on the basis of Embodiment 1: the outer walls of the two sides of the adjustment frame 20 are fixed with the same placement plate 7 by bolts, and the top of the placement plate 7 The outer wall is fixed with a plurality of hollow cylinders 13 by bolts, and the inner wall of the hollow cylinder 13 is rotatably connected with rolling balls 32. The small lifting objects can be placed by setting the placement plate 7, and the rolling balls 32 can be placed along the hollow cylinder. 13. The inner wall is free to roll, so that the direction of the lifting object can be adjusted conveniently, so that the lifting object does not need to be connected by a connecting piece, so that the speed of hoisting the lifting object can be improved.

[0039] In order to hoist small lifting objects; such as figure 2 As shown, th...

Abstract

The invention discloses a hoisting device for a gantry crane, which relates to the technical field of gantry crane hoisting; in order to ensure the safety during hoisting; it includes a reinforcing plate, the outer walls of both sides of the reinforcing plate are provided with bent pipes, and the bottom of the bent pipe is The outer wall is provided with an accommodating plate, and the inner wall on one side of the two accommodating plates is provided with two transverse slide bars, and the outer wall of the transverse slide bar is movably connected with two sliders, and the outer wall on one side of the slider and the accommodating The outer wall of one side of the board is clamped with the same spring one. The present invention is provided with a hoisting hook—the hoisting object can be suspended by a steel wire rope, so that it can be hoisted by a gantry crane. The lifting object pulls down the adjustment frame, so that the two sliders on the same transverse sliding bar move relative to each other, so that the lifting object can be buffered.

Description

technical field [0001] The invention relates to the technical field of gantry crane hoisting, in particular to a hoisting device of a gantry crane. Background technique [0002] The gantry crane is a deformation of the bridge crane and is mainly used for loading and unloading operations of outdoor cargo yards, material yards, and bulk cargo. The gantry crane has the characteristics of high site utilization, large operating range, wide adaptability, and strong versatility. , is widely used in port cargo yards. Gantry cranes need to use hoisting devices when lifting heavy objects, but the current hoisting device structure is relatively simple, that is, using hooks to lift heavy objects with wire ropes, so that hoisting less flexible. [0003] After searching, the Chinese patent application number is CN201710713003.3, which discloses a hoisting device, including a mounting base, a support assembly arranged on the mounting base, and a guide rod connecting the tops of the two su...
