Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of crane assembly, in particular to a tower crane tower body combination device and method. BACKGROUND

[0002] At present, when a high floor is built, a tower crane is usually arranged around the floor, so that the tower crane can lift heavy materials required during floor construction to the required height or move the heavy materials to the specified distance. At the same time, as the floor height increases layer by layer after being covered, the tower crane needs to be raised synchronously. The current tower crane is composed of multiple standard sections, a climbing section at the highest position, and a crane on the climbing section. The lowermost standard section is connected with the base, and when the tower crane needs to be raised, the standard section to be assembled is usually lifted to a predetermined height by the crane. Then the external standard section is placed in the climbing section and the corresponding standard sections are assembled, so as to complete the lifting of the crane. However, the current standard section assembly process has the following problems: 1. After the crane lifts the standard section to be assembled to a specified height, the standard section cannot be directly moved to the installed standard section, so more manual work is required to move the standard section and keep it in a normal posture (non-inclined state) before installation. This process consumes a lot of labor and makes it difficult to align the standard section with the installed standard section, making the assembly process difficult and tedious.

[0003] 2. After adjusting the standard section to be installed to a normal posture (non-inclined state), the standard section needs to be aligned with the installed standard section before installation, so installation without complete alignment may lead to installation failure or accidents.

[0019] Second, the annular strip and the corresponding annular groove in this invention cooperate with each other, and the guide plate and the corresponding guide groove cooperate with each other to guide the lowering process of the standard section, so as to facilitate the accurate stacking of the two standard sections. This ensures that the two standard sections are aligned before installation and assembly, thus ensuring the accuracy of the assembly of the two standard sections and avoiding the safety accident caused by the two standard sections not being aligned during installation.

[0020] Third, in this invention, the elastic force generated by the corresponding first spring drives the placement rod and the arc-shaped clamping plate to move toward the fixing thread, so that the arc-shaped clamping plate is inserted into the limiting groove, thus achieving the effect of pre-fixing the fixing thread, which facilitates the subsequent manual fixing of the fixing bolt.

Implementation

[0032] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] like Figure 1 As shown, a tower crane tower body assembly includes:

[0034] Standard section 1 includes a fixing plate 10 and a connecting pipe 11. There are four fixing plates 10 in L shape. All the fixing plates 10 in a standard section 1 are arranged in a matrix. The four fixing plates 10 are fixedly connected to each other by multiple connecting pipes 11.

[0035] The climbing section 2 is located on the upper end surface of the standard section 1 at the top. The climbing section 2 includes a base plate 20 and an annular plate 21. The upper end surfaces of the four uppermost fixed plates 10 are provided with base plates 20 for placing the crane. The lower end surfaces of the base plates 20 are fixedly provided with an annular plate 21 by multiple fixed columns.

[0036] A rectangular plate 3 is disposed between the base plate 20 and the annular plate 21, and the rectangular plate 3 is fixed on the corresponding fixed column. The opposing surfaces of the two rectangular plates 3 are provided with clamping mechanisms 4 for clamping the standard section 1, and the two clamping mechanisms 4 are symmetrical.

[0037] The connecting mechanism 5 is disposed between two adjacent fixing plates 10 on different standard sections 1.

[0038] The climbing mechanism 6 is located on the lower end face of the annular plate 21.

[0039] When the tower crane needs to be raised during operation, the climbing section 2 first raises itself and the crane on it to a certain height through the climbing mechanism 6. Then, the tower crane raises a standard section 1 to the left side of the climbing section 2. Then, the two clamping mechanisms 4 clamp the standard section 1 and move it to the installed standard section 1. The connecting mechanism 5 connects the standard section 1 to the original standard section 1. The upper end of the standard section 1 supports the base plate 20 and the tower crane on it, thus completing one raising process of the tower crane.

[0040] like Figure 4 , Figure 5 and Figure 6 As shown, the clamping mechanism 4 on the rear side will be described. The clamping mechanism 4 includes a first slide groove 40. The front end face of the rectangular plate 3 has two vertically distributed first slide grooves 40. The two first slide grooves 40 are slidably arranged with a vertical plate 41 through an electric slider. The front end face of the vertical plate 41 has a second slide groove 42. The second slide groove 42 is slidably arranged with an L-shaped plate 43 for lifting the standard section 1 through an electric slider. The L-shaped plate 43 is provided with a first clamping unit 44 for clamping the standard section 1 in the front-back direction and a second clamping unit 45 for clamping the standard section 1 in the left-right direction.

[0041] like Figure 5As shown, the first clamping unit 44 includes a slider groove 440. The upper end face of the L-shaped plate 43 has two left-right symmetrical slider grooves 440. An L-shaped receiving plate 441 for receiving the corresponding connecting pipe 11 is slidably arranged in the slider groove 440 by a slider. An arc-shaped block 442 for clamping the connecting pipe 11 is fixedly arranged on the upper end face of the horizontal part of the receiving plate 441, and the arc surface of the arc block 442 faces the rear side. A first cylinder 443 with a telescopic end fixedly connected to the receiving plate 441 is fixedly arranged on the front end face of the L-shaped plate 43.

[0042] like Figure 6 As shown, the second clamping unit 45 includes a rotating shaft 450. The rotating shaft 450 is rotatably mounted on the rear end face of the vertical part of the receiving plate 441. A first rotating plate 451 is fixedly mounted on the rotating shaft 450. A second rotating plate 452 is rotatably mounted on the rear end face of the first rotating plate 451 via a connecting shaft. A swing column 453 is movably mounted on both the first rotating plate 451 and the second rotating plate 452. A clamping roller 454 is rotatably mounted on the downward inclined part of the swing column 453 via a connecting plate. An L-shaped limiting plate 455 is fixedly mounted on the upward inclined part of the swing column 453. A driving unit 46 for driving the swing column 453 to swing is provided on the upper end face of the receiving plate 441.

[0043] like Figure 5 and Figure 6 As shown, the drive unit 46 includes a moving block groove 460. The upper end face of the vertical part of the receiving plate 441 has two symmetrical moving block grooves 460. A transverse moving plate 461 is slidably arranged in the moving block groove 460 through the moving block. A square block 462 is rotatably arranged on the rear end face of the transverse moving plate 461 through the connecting column. The directional block cooperates with the limiting plate 455. A mounting shaft plate 463 is fixedly arranged on the upper end face of the vertical part of the receiving plate 441. A bidirectional threaded shaft 464 connected to an external motor is rotatably arranged on the vertical plate 41. The bidirectional threaded shaft 464 and the transverse moving plate 461 are threadedly engaged.

[0044] During operation, when the tower crane lifts the standard section 1 to be assembled and moves it between two rectangular plates 3 and to the left side of the two rectangular plates 3, the upper connecting pipe 11 inside the standard section 1 is located on the receiving plate 441. Then, the external motor drives the bidirectional threaded shaft 464 to rotate. Through the threaded engagement between the bidirectional threaded shaft 464 and the transverse plate 461, the transverse plates 461 in the same drive unit 46 move away from each other. The transverse plate 461 drives the square block 462 to move synchronously. Through the engagement between the square block 462 and the corresponding limiting plate 455, the two swing columns 453 drive the clamping rollers 454 on them to swing synchronously. At this time, the two swing columns 453 slide relative to the first rotating plate 451 and the second rotating plate 452 respectively. Finally, the two clamping rollers 454 exert a downward pressure on the connecting pipe 11 they are in contact with. At the same time, the two clamping rollers 454 and the fixed plate on the same side exert a downward pressure on the connecting pipe 11. The plates 10 are pressed and pressed together, so that the standard section 1 is located in the middle of the receiving plate 441 in the left-right direction. The clamping roller 454 cooperates with the corresponding receiving plate 441 to place the standard section 1 stably on the receiving plate 441, which is convenient for subsequent installation and assembly. Then, the first cylinder 443 works to retract its telescopic end. At the same time, the other clamping mechanism 4 also performs the above operation. Therefore, the two corresponding receiving plates 441 drive the corresponding arc block 442 to contact the corresponding connecting pipe 11 and exert a pulling force on the connecting pipe 11. Thus, the standard section 1 is located in the middle of the two rectangular plates 3 in the front-back direction, which is convenient for subsequent assembly and installation of the standard section 1. After the two clamping mechanisms 4 clamp and fix the standard section 1, the electric slider one works to drive the vertical plate 41 and the standard section 1 to the center of the annular plate 21. The electric slider two works to drive the standard section 1 down through the L-shaped plate 43 and perform installation and assembly.

[0045] like Figure 7 As shown, the connecting mechanism 5 includes an upper connecting cylinder 50. Taking the two connecting mechanisms 5 on the left rear side as an example, the upper connecting cylinder 50 and the lower connecting cylinder 51 are fixedly installed on the left end face and the rear end face of the fixing plate 10 from top to bottom through connecting blocks. The upper connecting cylinder 50 and the lower connecting cylinder 51 are both cylindrical structures with open ends. The upper end face of the lower connecting cylinder 51 is provided with an annular groove 52. The lower end face of the upper connecting cylinder 50 is fixedly provided with an annular strip 520 that cooperates with and guides the annular groove 52. The upper connecting cylinder 50 and the lower connecting cylinder 51 are provided with a fixing bolt 53. The lower end of the fixing bolt 53 is provided with a nut that is threaded with it and used to fix the upper connecting cylinder 50 and the lower connecting cylinder 51. The upper end face of the fixing plate 10 is provided with an L-shaped guide groove 54. The lower end face of the fixing plate 10 is fixedly provided with a guide plate 540 that cooperates with the guide groove 54. The lower end of the guide plate 540 is chamfered.

[0046] like Figure 7 and Figure 8 As shown, the fixing bolt 53 has an annular limiting groove 55 in the middle, and both the upper and lower ends of the limiting groove 55 are arc-shaped. The circumferential surface of the lower connecting cylinder 51 is provided with a limiting unit 56, which includes a placement rod 560. The circumferential surface of the lower connecting cylinder 51 has multiple placement grooves communicating with its inner cavity. The placement rod 560 is slidably arranged in the placement groove. An arc-shaped clamping plate 561 is fixedly arranged at one end of the placement rod 560 near the fixing bolt 53. A spring mounting plate 562 is fixedly arranged at the other end of the placement rod 560. A first spring 563 is arranged between the spring mounting plate 562 and the lower connecting cylinder 51. A release unit 57 is provided on the spring mounting plate 562 on the same lower connecting cylinder 51.

[0047] like Figure 7 and Figure 8 As shown, the release unit 57 includes an inclined plate 570. The upper end of the spring mounting plate 562 is fixedly provided with the inclined plate 570. The circumferential surface of the lower connecting cylinder 51 is provided with vertical grooves 571 that correspond one-to-one with the inclined plates 570. U-shaped plates 572 are slidably arranged in all the vertical grooves 571 on the same lower connecting cylinder 51 through sliding blocks, and the U-shaped plates are in close contact with the corresponding inclined plates 570.

[0048] During operation, after the clamping mechanism 4 moves the standard section 1 to be installed directly above the installed standard section 1, the electric slider 2 causes the L-shaped plate 43 to move the standard section 1 downwards. The guide plate 540 on the lower fixing plate 10 engages with the guide groove 54 on the lower fixing plate 10 to guide the lowering process of the standard section 1. Simultaneously, the annular strip 520 on the upper connecting cylinder 50 engages with the annular groove 52 on the upper end face of the lower connecting cylinder 51, facilitating the mating of the upper and lower connecting cylinders 50 and 51. This allows the clamping mechanism 4 to place the standard section 1 onto the installed standard section 1. Then, the fixing bolt 53 is manually inserted into the corresponding lower connecting cylinder 51 through the upper connecting cylinder 50. During the insertion of the fixing bolt 53, the circumferential surface of the fixing bolt 53 first contacts the corresponding arc-shaped clamping plate 561, causing the arc-shaped clamping plate 561 and the placement rod 560 to move away from the threaded rod. Simultaneously, the corresponding first... When spring 563 is stretched, and the fixing bolt 53 has fully moved down, the limiting groove 55 area of ​​the fixing bolt 53 moves to align with the arc-shaped retaining plate 561. Therefore, the first spring 563 resets, and the spring mounting plate 562, through the elastic force generated by the corresponding first spring 563, drives the placement rod 560 and the arc-shaped retaining plate 561 towards the fixing bolt 53. At this point, the arc-shaped retaining plate 561 engages in the limiting groove 55, thus achieving a pre-fixing effect on the fixing bolt 53, facilitating subsequent manual fixing of the fixing bolt 53. After securing the standard section 1, the nut is manually installed onto the fixing bolt 53. When the standard section 1 needs to be removed later, the nut is first removed manually, and then the U-shaped plate 572 is pulled down. During the downward movement of the U-shaped plate 572, it presses against the inclined plate 570, thereby causing the inclined plate 570 to move the spring mounting plate 562, the corresponding placement rod 560, and the arc-shaped clamping plate 561 away from the fixing bolt 53. Then, the fixing bolt 53 is removed manually and the standard section 1 is removed through the clamping mechanism 4.

[0049] like Figure 2 and Figure 3 As shown, the climbing mechanism 6 includes a support block 60. The two longitudinal portions of the fixed plates 10 in the same column are fixedly provided with support blocks 60. The upper end of the support block 60 is grooved. A base rod 62 is placed on the support block 60. A hydraulic cylinder 61 is hinged to the lower end face of the annular plate 21. The telescopic end of the hydraulic cylinder 61 is fixedly provided with a connecting cylinder that is fixedly connected to the base rod 62.

[0050] Before clamping and assembling the standard section 1, the hydraulic cylinder 61 first retracts its telescopic end, and at this time, its telescopic end moves through the connecting cylinder to the receiving block 60 on the two adjacent fixed plates 10 inside the standard section 1, and the base rod 62 is located in the groove of the receiving block 60. Then, all the hydraulic cylinders 61 work at the same time to extend their telescopic ends, so that the climbing section 2 moves upward through the annular plate 21, thereby providing space for assembling and assembling the standard section 1.

[0051] In addition, the present invention also provides a method for assembling the tower body of a tower crane, including the following steps: S1, raising the climbing section: the hydraulic cylinder 61 works to retract its telescopic end, and at this time its telescopic end moves to the receiving block 60 on the two adjacent fixed plates 10 in the standard section 1 through the connecting cylinder, and the base rod 62 is located in the groove of the receiving block 60. Then all the hydraulic cylinders 61 work at the same time to extend their telescopic ends, so the climbing section 2 moves upward through the annular plate 21.

[0052] S2. Clamping the standard section: When the external motor operates, it drives the bidirectional threaded shaft 464 to rotate, which causes the two swing columns 453 to drive the clamping rollers 454 on them to swing synchronously. Ultimately, the two clamping rollers 454 exert a downward pressure on the connecting pipe 11 they are in contact with. At the same time, the two clamping rollers 454 and the fixing plate 10 on the same side are in close contact and squeezed against each other, so that the standard section 1 is located in the middle position of the receiving plate 441 in the left-right direction.

[0053] Then, the first cylinder 443 operates, causing its telescopic end to retract. This causes the receiving plate 441 to drive the arc-shaped surface of the corresponding arc-shaped block 442 to contact the connecting pipe 11 at the corresponding position and exert a pulling force on the connecting pipe 11. As a result, the standard section 1 is positioned in the middle of the two rectangular plates 3 in the front-back direction. Thus, the two clamping mechanisms 4 complete the clamping and fixing of the standard section 1 that needs to be combined.

[0054] After the two clamping mechanisms 4 clamp and fix the standard section 1, the electric slider one works to drive the vertical plate 41 and the standard section 1 to the center position of the annular plate 21, and the electric slider two works to drive the standard section 1 down through the L-shaped plate 43 and install and assemble it.

[0055] S3. Assemble the standard section: The electric slider 2 operates to move the L-shaped plate 43 to move the standard section 1 downward. The guide plate 540 on the fixed plate 10 inside the downward moving plate cooperates with the guide groove 54 on the fixed plate 10 below to guide the lowering process of the standard section 1, so that the standard section 1 is placed on the already installed standard section 1. Then, the fixing bolt 53 is manually inserted into the corresponding lower connecting cylinder 51 through the upper connecting cylinder 50, and the nut is installed on the fixing bolt 53 to complete the fixed installation between the two standard sections 1.

[0056] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0057] Furthermore, the terms "first," "second," "number one," and "number two" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first," "second," "number one," or "number two" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0058] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," "installed," and "connected" should be interpreted broadly.
