Abstract
Description
Technical Field
[0001] The present application relates to the technical field of hoisting equipment for lifting and transporting, and in particular to a crane structure for auxiliary transport of tree transplanting. Background Art
[0002] Greening treatments will be carried out in existing buildings, transportation, public facilities and other fields to improve the ornamental and comfort of the environment. After the completion of various construction projects, green plants will be planted. In terms of the types of green plants, in addition to shrubs and vegetation covering the ground, some tall tree-like landscape trees will also be planted. These tree-like landscape trees need to be transplanted from gardens, nurseries and other places, which requires transfer equipment and lifting equipment; in the existing lifting process, cranes, truck cranes and other lifting equipment are often used for auxiliary lifting. However, due to the high value of some horticultural trees, the existing cranes and other lifting equipment have only one force point during the lifting process, which cannot adapt well to the growth posture of the trees, and easily cause local force imbalance, which in turn causes the lifting process to be difficult. The posture of trees is prone to change, resulting in more cases of branch breakage and bark peeling at the lifting point, which causes damage to trees, especially high-value horticultural trees, affects the survival rate of transplantation, and causes unexpected economic losses. For example, the forestry handling and lifting equipment published by the existing patent number CN118529630A can improve the lifting efficiency, but it can only be adapted to relatively straight trees such as street trees. It still cannot be well adapted to the lifting of some horticultural trees with inclined growth and other postures that are not straight or have a relatively curved posture. The connection convenience is poor, which affects the lifting efficiency. If forced lifting is performed, it will still cause damage to such trees. Therefore, there is still a need to improve the existing lifting equipment, and then propose a crane structure for auxiliary handling of forestry transplanting to solve these problems.

DETAILED DESCRIPTION
[0021] The present application is further described in detail below in conjunction with the accompanying drawings.

[0023] In the existing tree transplanting process, for convenience, cranes are used for lifting. However, the prices of existing cranes vary, and there is a lack of cranes in some remote areas, resulting in inaccurate transplanting time of trees, affecting the construction period. Therefore, vehicle-mounted lifting equipment is often used to lift trees. However, this type of equipment can meet the lifting needs of ordinary trees. However, for some high-value horticultural trees, a single lifting point structure cannot meet their lifting needs, and manual construction of the frame is required for lifting and transportation. However, it takes a lot of time and affects work efficiency. Therefore, it is necessary to improve the existing lifting and hoisting equipment to solve these problems.

The positioning nut 8 can position the guide sleeve 7 after the position is adjusted, and at least two positioning nuts 8 are arranged on both sides of the guide sleeve 7 to ensure that it does not loosen after positioning. Generally, double nuts can be squeezed against each other to meet temporary According to the lifting requirements, the rope winding module 24 is capable of supporting each lifting rope 9, so that each lifting rope 9 can be retracted and retracted separately, and with mutual cooperation, trees in different postures can be lifted.
