Description

Technical Field

[0001] The present invention belongs to the technical field of lifting equipment, and in particular relates to a lifting equipment and an assembly method of the lifting equipment. Background Art

[0002] As a kind of handling mechanical equipment for lifting, lowering and horizontally moving materials, lifting equipment is widely used in different fields such as industry, transportation, and construction. Lifting equipment includes a tower body, a boom, and a counterweight. The bottom of the tower body is vertically connected to the ground, the middle of the boom is connected to the top of the tower body, and the boom can rotate relative to the tower body. A lifting device (such as an electric hoist) is set at one end of the boom, and the counterweight is connected to the other end of the boom.

[0003] In the related art, in order to facilitate the handling or transfer of lifting equipment, lifting equipment is generally an assembled structure. That is, the tower body and boom of the lifting equipment are formed by multiple standard sections of steel structures. Before the lifting equipment is used, 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 two adjacent tower bodies are connected together, so that the installation of the tower body can be completed. After that, multiple standard sections of the boom are installed together to form a boom. The boom is hoisted to the top of the tower body, and the boom is rotatably connected to the tower body. Finally, the counterweight is installed on the boom, and the assembly of the lifting equipment can be completed.

[0004] However, when assembling the lifting equipment, since the standard sections of the tower body are stacked in order from low to high, and the boom is installed after the tower body is assembled, other lifting equipment will inevitably be used during assembly, resulting in high installation costs. For some small and remote sites, the lifting equipment may not be available, resulting in the inability to install the lifting equipment, which limits the use of the lifting equipment. In addition, when fixing the standard sections of two adjacent tower bodies, the staff is also required to gradually rise with the height of the standard sections of the tower body.

[0034] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0035] The present disclosure provides a lifting device, such as Figure 1 As shown, the lifting equipment includes a tower body 100 , a lifting structure 200 , a rotating structure 300 and a boom 400 .

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

[0037] Figure 2 A schematic diagram of initial installation of a lifting device provided in an embodiment of the present disclosure, Figure 3 for Figure 2 The subsequent installation diagram in Figure 2 and Figure 3 . The bottom of the jacking structure 200 is connected to the first tower body standard section 101, and the top of the jacking structure 200 is detachably connected to the target tower body standard section 103, and 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 nth second tower body standard section 102 is installed. 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, where n is a natural number greater than 1. The arm 400 is rotatably connected to the top of the tower body 100 through the rotating structure 300.

[0038] When using the lifting equipment provided by the embodiment of the present disclosure, since the tower body 100 in the lifting equipment includes a plurality of tower body standard sections 100a stacked in sequence along the vertical direction, and two adjacent tower body standard sections 100a are detachably connected, the number of 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 lifting equipment further comprises a lifting structure 200, and the bottom of the lifting structure 200 is connected to the first tower body standard section 101, and the top of the lifting structure 200 is detachably connected to the target tower body standard section 103, the lifting 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 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. In this way, when installing the lifting equipment, the first tower body standard section 101 can be fixed on the ground first, and then the first second tower body standard section 102 can be installed on the first tower body standard section 101. 2. Afterwards, when installing the nth second tower body standard section 102, the target tower body standard section 103 adjacent to the first tower body standard section 101 can be driven upward by the jacking structure 200, so that an installation space 1020 for installing the nth second tower body standard section 102 is formed above the first tower body standard section 101, so as to install the nth second tower body standard section 102, so that the second tower body standard section 102 to be installed is always in an upper position adjacent to the first tower body standard section 101, thereby reducing the installation height of the tower body standard section 100a, avoiding the use of other hoists to hoist the standard section and avoiding manual high-altitude operations, reducing the operation cost, and improving the safety of the operation.

[0040] That is to say, in the above lifting equipment, since the jacking structure 200 is additionally provided and the jacking structure 200 is detachably connected to 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 an 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, thereby reducing the height of the installation of the second tower body standard section 102, thereby reducing the installation cost and improving the safety of the installation.

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

[0042] A plurality of driving cylinders 202 are arranged at intervals around the first tower body standard section 101 , and a cylinder body of each driving cylinder 202 is connected to the base 201 , and a telescopic end of the driving 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 an installation foundation 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 an installation space 1020 between the first tower body standard section 101.

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

[0045] Then, the driving cylinder 202 is controlled to extend, so that an installation 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 installation space 1020, and the second second tower body standard section 102 is respectively fixed to the first second tower body standard section 102 and the first tower body standard section 101. Then, the connection between the driving cylinder 202 and the first second tower body standard section 102 is disassembled, and the driving 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 (that is, the so-called target tower body standard section 103), and the drive cylinder 202 is controlled to extend, so that the installation 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 installation 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. The connection between the drive cylinder 202 and the second second tower body standard section 102 is disassembled, 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 extended again, so that the installation space 1020 is formed between the third second tower body standard section 102 and the first tower body standard section 101. Repeat the above steps until all the standard sections are installed.

[0047] In the embodiment of the present disclosure, the driving cylinders 202 are all electric cylinders for convenient control. The driving cylinders 202 are powered by motors, so that the entire lifting structure 200 is fully electrically driven, which is convenient for quick wiring and installation, and can also be remotely controlled by a remote controller.

[0048] The base 201 is a flat plate structure, which can simplify the structure of the base 201, making it easy to arrange and low in cost.

[0049] In other examples, the lifting structure 200 may also have other structures, such as a gear rack structure and the like.

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

[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 driving 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 the four corners of the first tower body standard section 101 are provided with drive cylinders 202, so that the target tower body standard section 103 can be smoothly supported and lifted by the drive cylinders 202, avoiding shaking and improving stability.

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

[0054] Moreover, two latches 203 are provided and arranged according to the diagonal of the tower body standard section 100a, so that each latch 203 can simultaneously connect the piston rods of two driving cylinders 202 and the target tower body standard section 103, and conveniently and quickly realize the connection between the driving cylinder 202 and the target tower body standard section 103. Moreover, the driving cylinders 202 can also be related to each other to ensure that they can act synchronously.

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

A pin hole 1000 for inserting the pin 203 is provided in the side wall of each main chord 1021.

[0058] The axis of the latch hole 1000 is perpendicular to the main chord 1021 , and the latch holes 1000 in the two main chords 1021 that are farthest apart are coaxially arranged.

[0059] The tower body standard section 100a is configured as the above structure, and the main chord 1021 can be used as the main load-bearing component, and the structure of the tower body standard section 100a can be simplified and the weight can be reduced. At the same time, a latch hole 1000 is provided in the main chord 1021, which also facilitates the insertion of the latch 203 to achieve the connection or disassembly between the drive cylinder 202 and the tower body standard section 100a.

In two adjacent tower body standard sections 100a, each protrusion 1001 of one tower body standard section is used to be inserted into the positioning hole 1002 of the other tower body standard section 100a. After the protrusion 1001 is inserted into the positioning hole 1002, the two adjacent tower body standard sections 100a can be connected by fasteners such as latches.

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

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

[0086] On the other hand, an embodiment of the present disclosure further provides an assembly method of a lifting device, and the assembly method is used to install the lifting device mentioned above.

[0087] Fig. 9 A schematic diagram of the installation sequence of the lifting equipment provided in the embodiment of the present disclosure, combined with Fig. 9 , the assembly method includes:

[0088] (1) Connect the first tower standard section to the site of use.

[0089] See also Fig. 9 As shown in Figure a, the bottom of the first tower standard section is connected to the ground by bolts and other fasteners.

[0090] (2) Connect the first second tower body standard section to the first tower body standard section.

[0091] See also Fig. 9 In Figure b, the first second tower body standard section is superimposed on the first tower body standard section, and the two are connected together by bolts and other fasteners.

[0092] (3) Connect the arm to the first and second standard sections of the tower.

[0093] Since the overall structure of the boom is relatively large, the standard sections of the boom can be installed one by one when installing the boom.

[0094] The following steps are involved in connecting the boom to the first and second tower standard sections:

[0095] (3.1) Connect the first boom standard section of the lifting equipment to the first and second tower standard sections.

[0096] (3.2) Connect the other boom standard sections horizontally to the two ends of the first boom standard section.

[0097] See also Fig. 9 As shown in Figures c and d, during installation, the first boom standard section is first connected to the first and second tower body standard sections by means of a rotary structure 300. Then, the remaining boom standard sections are sequentially connected to the left and right ends of the first boom standard section until the length of the boom meets the actual requirements.

[0098] When installing two adjacent boom standard sections, you can refer to the above description, insert the positioning protrusion of one boom standard section into the positioning groove of the other boom standard section, and then fix the two adjacent boom standard sections together through the connecting piece.

[0099] It should be noted that when installing the boom standard sections, a counterweight can be installed on one of the boom standard sections to keep the boom balanced during installation.

[0100] After the boom is installed, a manual lifting component 600 may be connected to the end of the boom first, and then the automatic lifting component 500 may be installed in the guide rail formed by the standard section of the boom through the manual lifting component 600.

[0101] (4) Connect the jacking structure to the first second tower body standard section, dismantle the connection between the first second tower body standard section and the first tower body standard section, control the jacking structure to drive the first second tower body standard section to rise, so that an installation space is formed between the first second tower body standard section and the first tower body standard section.

[0102] See also Fig. 9 In Figure e, the lifting structure in the lifting equipment is controlled to drive the first second tower body standard section (that is, the first target tower body standard section 103) to rise, so that an installation space 1020 is formed between the first second tower body standard section and the first tower body standard section.

[0103] (5) Insert the second second tower body standard section 102 into the installation space 1020, and connect the two ends of the second second tower body standard section to the two adjacent tower body standard sections respectively.

[0104] See also Fig. 9 As shown in Figure f, after the installation space is formed, the second second tower body standard section can be inserted into the installation space so that the two ends of the second second tower body standard section are respectively positioned together with the first tower body standard section and the first second tower body standard section. Then, the two ends of the second second tower body standard section are respectively fixed together with the first tower body standard section and the first second tower body standard section by bolts and other fasteners.

[0105] (6) Dismantle the connection between the jacking structure and the first and second tower body standard sections, and control the jacking structure to reset to the first tower body standard section.

[0106] Connect the jacking structure to the second standard section of the second tower.

[0107] See also Fig. 9 As shown in Figure g, after dismantling the connection between the jacking structure and the first and second tower standard sections, the jacking structure is controlled to reset.

[0108] (7) Repeat the previous three steps until all standard sections of the second tower body are installed.

[0109] After the jacking structure and the second second tower body standard section are fixed together by bolts, etc., it is convenient to drive the second second tower body standard section to rise. Then continue to control the jacking structure to drive the second second tower body standard section to rise, so that an installation space is formed between the second second tower body standard section and the first tower body standard section. After the installation space is formed, the third second tower body standard section is inserted into the installation space. Repeat this process until all second standard sections are installed.

[0110] In the above process of installing the tower body 100, the space between the target tower body standard section 103 and the first tower body standard section 101 can be adjusted at any time to form an 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, thereby reducing the height of installing the second tower body standard section 102, thereby reducing the installation cost and improving the safety of installation.

[0111] The above description is only an optional embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the protection scope of the present disclosure.
