That is, the tower body and the arm support of the hoisting equipment are formed by a plurality of steel standard sections. Before use, the first standard section of the tower body is connected to the ground. Then, the other standard sections are stacked in sequence, and the standard sections of the adjacent two tower bodies are connected together, so that the installation of the tower body is completed. Then, the plurality of standard sections of the arm support are installed together to form the arm support. The arm support is hoisted to the top of the tower body, and the arm support is rotationally connected to the tower body. Finally, the counterweight is installed on the arm support, so that the hoisting equipment is assembled.

[0004] However, when assembling the hoisting equipment, since the standard sections of the tower body are stacked in sequence from low to high, and the installation of the arm support is hoisted after the tower body is assembled, other lifting tools are inevitably used during assembly, resulting in high installation cost.

[0034] In order to make the objects, technical solutions and advantages of the present disclosure clearer, the following will further describe the embodiments of the present disclosure in detail with reference to the drawings.

[0035] The present disclosure provides a hoisting device, such as Figure 1 As shown in the figure, the hoisting device comprises a tower body 100, a jacking structure 200, a slewing structure 300 and a jib 400.

[0036] The tower body 100 comprises a plurality of tower body standard sections 100a stacked in sequence along the vertical direction, and adjacent two tower body standard sections 100a are detachably connected. The tower body standard section 100a at the bottom is a first tower body standard section 101, and the other tower body standard sections 100a above the first tower body standard section 101 are all second tower body standard sections 102.

[0037] Figure 2 The initial installation schematic diagram of the hoisting device provided by the present disclosure is shown in Figure 3 The subsequent installation schematic diagram in Figure 2 is shown in combination with Figure 2 and Figure 3 . The bottom of the jacking structure 200 is connected with the first tower body standard section 101, and the top of the jacking structure 200 is detachably connected with a target tower body standard section 103. The target tower body standard section 103 is a second tower body standard section 102 adjacent to the first tower body standard section 101 before the installation of the nth second tower body standard section 102. The jacking structure 200 is used to drive the target tower body standard section 103 to move away from the first tower body standard section 101, so that an installation space 1020 for the installation of the nth second tower body standard section 102 is formed between the first tower body standard section 101 and the target tower body standard section 103, wherein n is a natural number greater than 1. The jib 400 is rotationally connected with the top of the tower body 100 through the slewing structure 300.

[0038] When the hoisting device is used, since the tower body 100 in the hoisting device comprises a plurality of tower body standard sections 100a stacked in sequence along the vertical direction and detachably connected between adjacent two tower body standard sections 100a, the number of the tower body standard sections 100a can be increased or decreased according to actual needs, so as to flexibly adjust the height of the tower body.

[0039] Since the hoisting device further comprises the jacking structure 200, the bottom of the jacking structure 200 is connected with the first tower body standard section 101, the top of the jacking structure 200 is detachably connected with the target tower body standard section 103, and the jacking structure 200 is used to drive the target tower body standard section 103 to move away from the first tower body standard section 101, so that the installation space 1020 for installing the nth second tower body standard section 102 is formed between the first tower body standard section 101 and the target tower body standard section 103, so that when the hoisting device is installed, the first tower body standard section 101 can be first fixed on the ground, then the first second tower body standard section 102 is installed on the first tower body standard section 101, and then when the nth second tower body standard section 102 is installed, the target tower body standard section 103 adjacent to the first tower body standard section 101 is first driven to move upward by the jacking structure 200, so that the installation space 1020 for installing the nth second tower body standard section 102 is formed above the first tower body standard section 101, the nth second tower body standard section 102 is installed, the second tower body standard section 102 to be installed is always in the position adjacent to the first tower body standard section 101, the installation height of the tower body standard section 100a is reduced, the standard section is avoided to be hoisted by other lifting appliances, manual high-altitude operation is avoided, the operation cost is reduced, and the safety of the operation is improved.

[0040] That is to say, in the above hoisting device, since the jacking structure 200 is additionally arranged and detachably connected between the first tower body standard section 101 and the target tower body standard section 103, the space between the target tower body standard section 103 and the first tower body standard section 101 can be adjusted at any time during the installation of the tower body 100 to form the installation space 1020, so that the second tower body standard section 102 to be installed is always adjacent to the first tower body standard section 101, the installation height of the second tower body standard section 102 is reduced, and thus the installation cost is reduced and the safety of the installation is improved.

[0041] Continuing to refer to Figure 2 and Figure 3 Optionally, the jacking structure 200 comprises a base 201 and a plurality of driving cylinders 202, the base 201 is located at the bottom of the first tower body standard section 101 and connected with the first tower body standard section 101.

[0042] A plurality of drive cylinders 202 are arranged at intervals along the periphery of the first tower body standard section 101, and the cylinder body of each of the plurality of drive cylinders 202 is connected to the base 201, and the telescopic end of the drive cylinder 202 is detachably connected to the target tower body standard section 103.

[0043] In the above implementation, the base 201 is used to provide a mounting base for the drive cylinder 202, and is connected to the first tower body standard section 101. The drive cylinder 202 is used to be detachably connected to the target tower body standard section 103, so as to drive the target tower body standard section 103 to form a mounting space 1020 in front of the first tower body standard section 101.

[0044] For example, when actually installing the tower body 100, the first tower body standard section 101 can be installed on the ground first, and then the first second tower body standard section 102 is installed on the first tower body standard section 101, and the first second tower body standard section 102 is connected to each drive cylinder 202.

[0045] Then the drive cylinder 202 is controlled to be elongated, so that the mounting space 1020 is formed between the first second tower body standard section 102 and the first tower body standard section 101. The second second tower body standard section 102 is inserted into the mounting space 1020, and the second second tower body standard section 102 is fixed to the first second tower body standard section 102 and the first tower body standard section 101 respectively. Then the connection between the drive cylinder 202 and the first second tower body standard section 102 is detached, and the drive cylinder 202 is retracted to the first tower body standard section 101.

[0046] Then the drive cylinder 202 is connected to the second second tower body standard section 102 (also called the target tower body standard section 103), and the drive cylinder 202 is controlled to be elongated, so that the mounting space 1020 is formed between the second second tower body standard section 102 and the first tower body standard section 101. The third second tower body standard section 102 is inserted into the mounting space 1020, and the third second tower body standard section 102 is fixed to the second second tower body standard section 102 and the first tower body standard section 101 respectively. Then the connection between the drive cylinder 202 and the second second tower body standard section 102 is detached, and the drive cylinder 202 is retracted to the first tower body standard section 101. The drive cylinder 202 is connected to the third second tower body standard section 102, and then the drive cylinder 202 is elongated, so that the mounting space 1020 is formed between the third second tower body standard section 102 and the first tower body standard section 101. The above steps are repeated until all the standard sections are installed.

[0047] In this embodiment, all drive cylinders 202 are electric cylinders for easy control. The drive cylinders 202 are powered by motors, making the entire lifting structure 200 fully electrically driven, facilitating quick wiring and installation, and allowing for remote control via a remote controller.

[0048] The base 201 has a flat plate structure, which simplifies the structure of the base 201, makes it easy to arrange, and reduces costs.

[0049] In other examples, the lifting structure 200 can also be other structures, such as a gear and rack structure, etc.

[0050] Figure 4 for Figure 2 or Figure 3 A top view of the first standard section of the tower, combined with Figure 4 Optionally, the standard tower section 100a is a cuboid frame structure. There are four drive cylinders 202, which are located at the four corners of the cross-section of the first standard tower section 101, and the extension and retraction direction of the drive cylinders 202 is vertical.

[0051] The lifting structure 200 also includes two pins 203. The length direction of each pin 203 is arranged along the diagonal of the first tower body standard section 101, and the two ends of each pin 203 are respectively used to be inserted into the piston rods of the two drive cylinders 202, and the middle part of the pin 203 is used to be inserted into the target tower body standard section 103.

[0052] In the above implementation, there are four drive cylinders 202, so that drive cylinders 202 are provided at the four corners of the first tower standard section 101, so that the target tower standard section 103 can be smoothly supported and raised by the drive cylinders 202, avoiding swaying and improving stability.

[0053] The pin 203 is used to detachably connect the target tower standard section 103 and the piston rod of the drive cylinder 202, so that the target tower standard section 103 and the drive cylinder 202 can be connected and disassembled at any time.

[0054] Furthermore, by setting two pins 203 and arranging them diagonally along the standard tower section 100a, each pin 203 can simultaneously connect the piston rods of the two drive cylinders 202 and the target standard tower section 103, facilitating a quick and easy connection between the drive cylinders 202 and the target standard tower section 103. This also allows the drive cylinders 202 to be interconnected, ensuring synchronized operation.

[0055] In other examples, the number of pins may also be four, corresponding one-to-one with the four drive cylinders 202. The pins 203 may also be other structures, such as bolt fasteners.

[0059] By setting the tower body standard section 100a as the above structure, the main chord rod 1021 can be used as the main load-bearing component, while simplifying the structure of the tower body standard section 100a and reducing the weight. At the same time, the pin hole 1000 is provided in the main chord rod 1021, which is convenient for the insertion of the pin 203, so as to realize the connection or disassembly between the driving cylinder 202 and the tower body standard section 100a.

In adjacent two tower body standard sections 100a, the protrusions 1001 of each tower body standard section are inserted into the positioning holes 1002 in the other tower body standard section 100a. After the protrusion 1001 is inserted into the positioning hole 1002, the adjacent two tower body standard sections 100a can be connected by fasteners such as pins.

[0062] In the above implementation, the flange plate 1022 is used to increase the contact area of the two adjacent tower body standard sections 100a, so that the tower body standard sections 100a can be stacked together stably. Moreover, installation space is also provided for fasteners such as bolts, so that the connection and disconnection between the two adjacent tower body standard sections 100a can be realized through the fasteners.

[0063] In the embodiments of the present disclosure, a plurality of web chords 1023 are sequentially connected along the length direction of the main chord 1021 between the two adjacent main chords 1021, and the two ends of each web chord 1023 are connected with the two adjacent main chords 1021, respectively. In this way, the two adjacent main chords 1021 can be connected through the web chords 1023, so as to further increase the structural strength of the tower body standard section 100a.

[0064] Optionally, the height of the tower body standard section 100a is 500mm-800m.
