[0029] Existing folding jib cranes generally directly set different types and select the types according to different situations. Among them, the installation process of various folding jib cranes is complex and the versatility is poor. Therefore, it is considered to adopt a splicing method to form a jib through multi-joint splicing, which is convenient for installation and flexible in use.

[0030] Please refer to Figure 1 , the present utility model provides a hoisting tooling 100, including a hoisting jib 1. The hoisting jib 1 includes an installation end and a lifting end arranged oppositely. The installation end is formed with a docking structure for docking to an installation base, and the lifting end is formed with an installation structure for installing a lifting device; the length of the hoisting jib 1 can be adjusted so that the distance between the docking structure and the installation structure can be adjusted.

[0031] In a hoisting tooling 100 provided by the present utility model, it includes a hoisting jib 1. The installation end of the hoisting jib 1 is used to be docked to an installation base, so that the whole hoisting jib 1 has an installation foundation. An installation structure is arranged on the lifting end for lifting operation. Among them, the overall length of the hoisting jib 1 can be adjusted, so that the distance between the docking structure and the installation structure can be adjusted, thereby realizing the adjustment of the lifting position and the installation position, so as to adapt to different lifting positions and lifting spaces. When in need of use, adjust the length of the hoisting jib so that the distance between the installation structure and the docking structure can meet the requirements, and then install the hoisting jib on the installation base for hoisting operations, with better versatility.

[0032] It should be noted that in the hoisting jib, the length between the installation end and the lifting end is set to be adjustable. Among them, there are various ways to adjust the length of the hoisting jib. For example, through telescopic members, the docking structure and the installation structure are arranged at both ends of the telescopic member to realize the adjustment of the length of the hoisting jib.

[0033] Please refer to Figure 2 , specifically, in this embodiment, the hoisting jib 1 includes a plurality of splicing members 11. Select different numbers of the splicing members 11 and splice them in sequence so that the distance between the docking structure and the installation structure can be adjusted. In this embodiment, the hoisting jib 1 is formed by splicing a plurality of the splicing members 11. When in use, the length of the hoisting jib 1 can be adjusted by selecting different numbers of the splicing members. The way of changing the length is simple, and the hoisting jib will not have an accidental length change during use. After splicing, the length remains in a determined state, and the posture is stable and reliable. The multi-joint jib structure is convenient for installation and flexible in use.

[0034] It should be noted that the splicing member 11 has multiple implementation manners. The splicing member 11 can be a rod body, and the ends of multiple rod bodies are sequentially connected to splice into the hoisting arm 1. Among them, there are also multiple implementation manners for the splicing positions between the splicing members 11. For example, the ends of the splicing members 11 are sequentially connected to form the overall hoisting arm, so that the two ends of the splicing member 11 are respectively connected to other splicing members 11, which is convenient for the setting of the splicing structure and the splicing operation of the splicing member 11.

[0035] In addition, each of the splicing members 11 can be exactly the same or can have different postures, such as setting different sizes, different bending angles, etc., as long as they can be spliced with each other.

[0036] In this embodiment, the splicing member 11 includes a splicing support column 11a. A plurality of connection structures are arranged along the length direction on the splicing support column 11a. Two adjacent splicing support columns 11a are arranged in parallel, and a plurality of the connection structures of two adjacent splicing support columns 11a are spliced with each other. In this embodiment, the splicing member 11 is the splicing support column 11a. Two adjacent splicing support columns 11a are arranged in parallel. After a plurality of the splicing support columns 11a are spliced, the splicing support column 11a itself can form a stress column structure, which can effectively avoid the deformation of the hoisting arm 1. At the same time, a plurality of the connection structures of two adjacent splicing support columns 11a are connected to each other, so that there are a plurality of splicing points between the two splicing support columns 11a, and the force transmission is more stable, avoiding deformation caused by single-point force, etc., and improving the use reliability of the hoisting arm 1.

[0037] Among them, a plurality of the connection structures are provided, and as long as they are arranged along the length direction of the splicing support column 11a, multi-point force in the length direction can be achieved, avoiding shaking of the splicing support column 11a, etc., and ensuring the stability of the structure forming the hoisting arm 1.

[0038] Specifically, two connection structures are provided, and the two connection structures are respectively arranged at the two ends of the splicing support column to achieve the force at the two ends of the splicing support column, and the force is more stable, avoiding shaking.

[0039] It should be noted that there are multiple connection manners between two adjacent splicing support columns 11a, as long as the connection between the splicing support columns 11a can be achieved. In one of the embodiments, a through hole is provided at the end of the splicing support column 11a, and the ends of the two splicing support columns 11a are connected by passing a pin shaft through the through holes of the two splicing support columns 11a, or a snap connection manner is adopted for connection.

[0040] Since the hoisting boom 1 needs to bear force, it is necessary to ensure the stability of the connection between the two splicing members. Therefore, in this embodiment, the connection structure includes a connecting member 21 and a fixing pin 22. One end of the connecting member 21 is formed with a docking protrusion 211, a through hole is penetrated through the side wall surface of the docking protrusion 211, and the other end is formed with a mating groove 212. The docking protrusion 211 is used to be arranged in the mating groove 212 of another connecting member 21, and an installation hole is provided on the side wall surface of the mating groove 212 corresponding to the through hole. The fixing pin 22 is penetrated through the installation hole and into the through hole. In this embodiment, the connecting member 21 is provided at the end of the splicing strut 11a. It can be connected to the mating groove of the previous splicing strut 11a through the docking protrusion 211, and the docking protrusion of the next splicing strut 11a can be fixed through the mating groove 212. Among them, during installation, after the docking protrusion 211 is installed into the mating groove 212, the adjacent ends of the two splicing struts 11a are fixed together by passing the fixing pin through the installation hole and the through hole, ensuring the stable connection of the two splicing struts 11a. The installation method is simple and reliable and convenient to operate.

[0041] It should be noted that the connecting member 21 has various implementation manners, as long as the docking protrusion 211 and the mating groove 212 can be formed at both ends. For example, directly in the form of a block, the docking protrusion 211 and the mating groove 212 are formed by protruding a protrusion and recessing a groove.

[0042] In this embodiment, the connecting member 21 includes two connecting plates. One ends of the two connecting plates are arranged at intervals to form the mating groove; the other ends are attached to each other to form the docking protrusion, so that the docking protrusion 211 and the mating groove 212 are respectively formed at both ends of the two connecting plates, and its own structure is simple and the weight is small, and it will not affect the overall force of the splicing member 11 during splicing.

[0043] In addition, there are also various installation methods between the connecting member 21 and the splicing member 11. It can be directly fixed on the splicing member 11 by welding, or can be fixed on the splicing member 11 by clamping, bolting, etc. It should be noted that in order to ensure the structural strength of the hoisting boom 1, the welding method is generally selected for fixing the connecting member 21.

[0044] On the other hand, the lifting arm 1 needs to perform lifting work at the lifting end. In order to improve the force and structural strength of the lifting arm 1, the overall shape of the lifting arm 1 should be gradually reduced in height from the installation end to the lifting end, so that the weight of the lifting section is lower, which is convenient for the end to bear greater force.

[0045] Therefore, in this embodiment, the length of the splicing support 11a is successively reduced from the docking structure to the mounting structure. In this embodiment, the length of the splicing support 11a is successively reduced, so that the overall shape of the lifting arm 1 is a right triangle, the cross-sectional height of the lifting end is small, and the weight is concentrated on the side of the mounting end, thereby ensuring the structural strength of the lifting arm 1. At the same time, the weight of the lifting arm 1 can be reduced as much as possible, so that the lifting end can bear more weight.

[0046] It should be noted that in the present application, the lengths of the splicing pillars 11a are not the same. In order to facilitate the connection between two adjacent splicing pillars 11a, the connecting piece 21 needs to take into account the installation angle, such as tilting at a certain angle to achieve the connection between adjacent connecting pieces 21. Since different connecting pieces 21 have different settings, there are many ways to connect connecting pieces 21 with certain differences in position, which need to be restricted and modified according to actual conditions. No specific explanation is given here. It is only necessary to be able to complete the connection between splicing pillars 11a of different lengths.

[0047] On the other hand, the lifting tool 100 further includes a transfer column 3, and the mounting end is fixedly mounted to the end of the transfer column 3. In this embodiment, the mounting end of the lifting arm 1 is fixedly mounted to the end of the transfer column 3, which facilitates the installation of the lifting arm 1 and provides a basis for the installation of the lifting arm 1.

[0048] It should be noted that the lifting arm 1 includes a plurality of splicing parts 11, including a fixed splicing part at the end of the installation end, wherein the fixed splicing part is used to be installed on the adapter column 3, so as to facilitate the installation of the lifting arm 1 and the adapter column 3.

[0049] Among them, there are many ways to install the lifting arm 1 and the adapter column 3. For example, the lifting arm 1 and the adapter column 3 are installed by welding, clamping, etc. In the embodiment provided by the utility model, connecting pin holes are respectively provided on the lifting arm 1 and the adapter column 3, and the installation of the lifting arm 1 and the adapter column 3 is achieved by manually passing the pin shaft through the connecting pin hole.

[0050] Furthermore, the lifting tool 100 further includes a universal support 4, which is used to be arranged in the transfer cabin, and the transfer column 3 is fixedly arranged on the universal support 4. In this embodiment, the universal support 4 facilitates the installation of the transfer column 3, facilitates the arrangement of the lifting arm 1 in the transfer cabin, and facilitates the use of the lifting tool.

[0051] It should be noted that there are many ways to connect the universal support 4 and the adapter column 3. For example, the universal support 4 and the adapter column 3 are connected by overlapping the rooting columns. There are many ways to connect the support and the column, which are not described in detail here.

[0052] On the other hand, in this embodiment, the mounting structure is used to install a lifting device. The mounting structure has a variety of implementations, as long as it is installed in conjunction with the lifting device, such as bolt hole coordination.

[0053] Specifically, in this embodiment, the lifting end is provided with a mounting hole, the mounting hole is used for mounting the lifting device, and the mounting hole forms the mounting structure. In this embodiment, the lifting device is mounted by means of a hole, which can be adapted to the installation of an existing lifting device without modifying the lifting device.

[0054] It should be noted that, in the present embodiment, the lifting arm 1 comprises a plurality of splicing pieces 11, each of which is formed with the mounting hole. Therefore, after the splicing is completed, the mounting holes on the splicing pieces 11 at the end of the lifting end will form the mounting structure, and there is no need to specially set up additional mounting components at the end for the installation of the lifting device, and the structure is simple and reliable.

[0055] On the other hand, the lifting tool 100 further includes a lifting arm 51 and a lifting hoist disposed on the lifting arm 51, and the lifting arm 51 is mounted to the lifting end. In this embodiment, the lifting function is also achieved by the lifting arm 51 and the lifting hoist disposed on the lifting arm 51.
