Problems solved by technology

In the construction of small structures, the hoisting height is short, and one section of the steel wire rope may be worn intensively; and the steel wire rope needs to be replaced as a whole after this section of steel wire rope is worn, and the cost is high
At the same time, the structure of the bridge anti-collision guardrail formwork installation and disassembly lifting device is relatively complicated and difficult to control

Embodiment 1

[0029] see Figure 1-Figure 6 , The present invention provides a small lifting distance crane for template and mold hoisting, including a frame 1; the frame 1 is the installation base of each component on the crane. The top of the frame 1 is provided with a lifting frame 7 that moves up and down, and support rods 8 are fixed at both ends of the lifting frame 7; For lifting and lowering, the lifting and lowering of the crane frame 7 needs to be equipped with a driving mechanism, and the driving mechanism can be a cam jacking mechanism 5 or a hydraulic jacking mechanism. The drive mechanism is arranged between the frame 1 and the crane frame 7 . Both ends of the frame 1 are rotatably connected with a synchronous swing mechanism 17 for balancing the crane frame 7 ; the first end of the synchronous swing mechanism 17 is rotatably connected with the corresponding support rod 8 above. Since the crane is used for lifting and transporting materials, when the materials are heavy and ...

Embodiment 2

[0039] see Figure 1-Figure 7 , the present invention provides a small lifting distance crane for template and mold hoisting. The following technical description is made from another aspect, so as to better understand the technical solution.

[0040] A small lifting distance crane for hoisting templates and molds, comprising a frame 1; a lifting frame 7 that moves up and down is arranged above the frame 1, and support rods 8 are fixed at both ends of the lifting frame 7; Both ends of the frame 1 are rotatably connected with a synchronous swing mechanism 17 for balancing the crane frame 7; A synchronous pull rod 6 is arranged between the synchronous swing mechanism 17; the end of the synchronous pull rod 6 is rotatably connected to the second end of the synchronous swing mechanism 17; the synchronous swing mechanism 17 or the hoisting frame 7 is connected with a lifting cable 13 , the free end of the hoisting cable 13 is connected with a hook 14; the two ends of the frame 1 ar...

Abstract

The invention relates to the technical field of cranes, and discloses a small-lifting-distance crane for hoisting a template and a mold, and the two ends of a rack are rotationally connected with synchronous swing mechanisms; the first ends of the synchronous swing mechanisms are rotationally connected with the corresponding supporting rods above, and meanwhile a synchronous pull rod is arranged between the two synchronous swing mechanisms. The synchronous swinging mechanism or the hoisting frame is connected with a hoisting cable; the two ends of the machine frame are provided with guiding pieces for centralizing the cable to vertically ascend and descend. According to the technical scheme, the material lifting stroke is short, the material lifting speed is high, the materials can be rapidly lifted and rapidly descended at a time, and the production efficiency is improved. The crane with the small lifting distance is simple in structure, and few parts need to be maintained; and under the action of the synchronous swinging mechanism, the equipment is stable in structure and stable in work. Meanwhile, the length of the hoisting cable for hoisting does not need to be too long, and the problems that abrasion is fast, and part of the hoisting cable is idle and useless do not exist.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a small lifting distance crane for hoisting templates and moulds, which is especially suitable for lifting and hoisting moulds or templates during continuous construction in civil engineering. Background technique [0002] In the construction of civil engineering, it is necessary to cast or prefabricate the curb on site through the curb stone mold, and need to use the template to cast or prefabricate the anti-collision guardrail on site. structures. Cranes need to be used in the installation and disassembly of the above-mentioned templates and molds. In the prior art, the crane has a complex structure, a large body, and a large lifting stroke; it is cumbersome and inflexible in the continuous pouring construction of the above-mentioned structures, and the operation is cumbersome; the cost of equipment maintenance and use is high. [0003] For example, the Chinese patent with the...
