Description

Technical Field

[0001] The present application belongs to the field of construction machinery, and in particular, relates to an attachment strut for a super-large tower crane and a super-large tower crane. Background Art

[0002] The super-large crane includes a tower body built along the height direction of the building. When the tower height is too high, the tower crane must be attached and reinforced. When attaching, first install the attachment frame on the tower body, and then hoist the attachment brace. The attachment brace is used to connect the tower body (including the attachment frame) to the building to improve the stability of the tower crane.

[0003] The various sections of the existing attachment struts are generally connected by flange plates. After the flange plates are welded and installed on the attachment struts, the flange plates will have certain welding deformation, resulting in excessive assembly gaps, which makes it impossible to ensure straightness and thus poses a safety hazard. In addition, the flange plates are heavy and require a large number of bolts for flange plate connection, which not only increases the weight of the attachment struts for super-large tower cranes, but also takes more time to install and disassemble. Summary of the invention

[0004] The purpose of the present application is to provide an attachment strut for a super-large tower crane and a super-large tower crane, which are more suitable for super-large tower cranes, are more convenient to install, and have higher safety.

[0005] To achieve the above-mentioned purpose, the present application provides, on one hand, an attachment brace for a super-large tower crane, the attachment brace comprising:

[0006] The main strut comprises a plurality of strut sections connected in succession along the axial direction of the main strut, and a first ear plate group and a second ear plate group are respectively arranged at both ends of the strut section;

[0007] An adjustable strut section is connected to the main strut along the axial direction of the main strut;

[0008] Wherein, adjacent strut sections are connected in alignment via a first ear plate group and a second ear plate group, and the first ear plate group and the second ear plate group are detachably connected via a plurality of non-coaxially arranged pins.

[0009] In some embodiments, the strut segment includes a main limb, and a first ear plate group and a second ear plate group are provided at both ends of the main limb, the first ear plate group includes a first end plate installed at one end of the main limb and a first ear plate and a second ear plate extending from the first end plate along the axial direction of the main strut; the second ear plate group includes a second end plate installed at the other end of the main limb and a third ear plate extending from the second end plate along the axial direction parallel to the main strut;

[0010] Among them, in the first ear plate group and the second ear plate group connected in opposition, the third ear plate is inserted into the ear plate groove between the first ear plate and the second ear plate along the axial direction of the main support rod, and is connected by a pin shaft that passes through the first ear plate, the third ear plate and the second ear plate in sequence.

[0011] In some embodiments, in the first ear plate group and the second ear plate group that are aligned and connected, the first ear plate, the third ear plate, and the second ear plate are connected through a plurality of pins that are arranged in parallel and spaced apart.

[0012] In some embodiments, the first ear plate, the third ear plate, and the second ear plate each include at least two unit ear plates, and each unit ear plate is provided with a pin shaft hole.

[0013] In some embodiments, the adjustable strut segment is also connected to the main strut through a first ear plate group and a second ear plate group that are aligned and connected.

[0014] In some embodiments, the adjustable strut segment is a welding segment, and the welding segment includes a first welding segment and a second welding segment for on-site welding.

[0015] In some embodiments, the first welding section includes a first end plate and a second end plate that are arranged in parallel and spaced apart and extend along the axial direction of the main support rod, and a receiving space is formed between the first end plate and the second end plate; the second welding section is a box beam structure that is adjustable in length along the axial direction of the main support rod and is inserted into the receiving space.

[0016] In some embodiments, a guide plate for guiding and plugging the box beam structure is provided on the contact plate surface between the first welding section and the second welding section.

[0017] In some embodiments, the second welding section is a tip box beam suitable for being inserted into the receiving space.

[0018] In some embodiments, the first welding section further includes a U-shaped plate for encircling the first end plate and the second end plate.

[0019] The present application also provides a super-large tower crane, which includes the above-mentioned attachment strut for the super-large tower crane.

[0020] In the technical solution of the present application, after the strut sections of the main strut are connected in alignment through the first ear plate group and the second ear plate group, the adjustable strut section is connected to the main strut along the axial direction of the main strut, so that the length of the attached strut and the distance between the super-large tower crane and the building can be accurately matched. Compared with the existing method of connecting the main strut structures through flange plates, the weight and size of the ear plate are smaller than the flange plate. Therefore, in the process of welding the ear plate group to the strut section, the welding deformation of the first ear plate group and the second ear plate group is very small, and the position accuracy of the ear plate group after welding is high. By ensuring the position accuracy of the ear plate group, the straightness of the main strut can be guaranteed when the strut sections are spliced ​​and formed. At the same time, during the pairing process of the first ear plate group and the second ear plate group, there is an adjustment gap between the male ear plate and the female ear plate, and the adjustment gap can reduce the difficulty of aligning the ear plates, making it easier to splice the strut sections, and the ear plates are fixed with pins, which are more convenient to disassemble than bolts, that is, the strut sections are connected by using pin ear plates, which can also increase the on-site assembly rate of the attached struts and reduce the on-site assembly difficulty of the attached struts. Furthermore, for super-large tower cranes, a large number of strut sections are required, and the first ear plate group and the second ear plate group are lighter than the flange plate. By using the ear plate connection, the overall weight of the attached strut can be effectively reduced, making the attached strut more suitable for super-large tower cranes.

[0021] Other features and advantages of the embodiments of the present application will be described in detail in the subsequent detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0045] The attachment brace for a super-large tower crane and the super-large tower crane according to the present application will be described below with reference to the accompanying drawings.

[0046] The present application discloses a novel attachment brace for a super large tower crane, such as Figure 1 and Figure 2 As shown, an attachment strut in a specific embodiment includes:

[0047] The main strut 100 includes a plurality of strut sections 110 connected in series along the axial direction C of the main strut, and a first ear plate group 111 and a second ear plate group 112 are respectively provided at both ends of the strut section 110;

[0048] The adjustable strut section is connected to the main strut 100 along the axial direction C of the main strut;

[0049] The adjacent strut segments 110 are connected in alignment via a first ear plate group 111 and a second ear plate group 112 , and the first ear plate group 111 and the second ear plate group 112 are detachably connected via a plurality of non-coaxially arranged pins 120 .

[0050] Specifically, see Figures 3 to 6After selecting a predetermined number of strut segments 110 and connecting them with the first ear plate group 111 and the second ear plate group 112, the length of the main strut 100 and the distance between the super-large tower crane and the building can be roughly matched; after selecting an adjustable strut segment of appropriate length and axially connecting it with the main strut 100, the length of the attached strut and the distance between the tower crane and the building can be accurately matched, thereby improving the supporting effect of the attached strut on the super-large tower crane. However, in the prior art, the segments of the attached strut are generally connected by flange plates. After the flange plates are welded and installed on the main strut structure, certain welding deformation will occur on the flange plates, resulting in large assembly errors between the flange plates, and multiple bolts are required between the flange plates, making it difficult to ensure the installation accuracy; and the length of the attached strut required for the super-large tower crane is relatively long. After the main strut is connected with multiple flange plates, the accumulation of assembly errors between the strut segments makes it difficult to ensure the straightness of the main strut structure, reducing the safety of the attached strut. Compared with the prior art, the ear plate has a smaller weight and size than the flange plate. Therefore, in the process of welding the ear plate group to the strut segment, the welding deformation of the first ear plate group 111 and the second ear plate group 112 is very small, and the position accuracy of the ear plate group after welding is high. By ensuring the position accuracy of the ear plate group, the straightness of the main strut 100 can be ensured when the strut segment 110 is spliced ​​and formed. At the same time, in the process of matching the first ear plate group 111 and the second ear plate group 112, there is an adjustment gap between the male ear plate and the female ear plate. The adjustment gap can reduce the difficulty of aligning the ear plates, making it easier to splice the strut segment 110. The ear plates are fixed with a pin shaft, which is more convenient to disassemble than a bolt. That is, the strut segments 110 are connected by using a pin shaft ear plate, which can also increase the on-site assembly rate of the attached strut and reduce the on-site assembly difficulty of the attached strut. Furthermore, for super-large tower cranes, a large number of strut segments 110 are required, and the first ear plate group 111 and the second ear plate group 112 are lighter than the flange plate. By adopting the ear plate connection, the overall weight of the attached strut can be effectively reduced, making the attached strut more suitable for super-large tower cranes.

[0051] In this embodiment, if Figures 3 to 6 As shown, the strut segment 110 may include a main limb 113, and a first ear plate group 111 and a second ear plate group 112 are provided at both ends of the main limb 113. The first ear plate group 111 includes a front end plate installed at one end of the main limb 113 and a first ear plate and a second ear plate extending from the front end plate along the axial direction C of the main strut; the second ear plate group 112 includes a rear end plate installed at the other end of the main limb 113 and a third ear plate extending from the rear end plate along the axial direction C parallel to the main strut.

[0052] Among them, in the first ear plate group 111 and the second ear plate group 112 that are connected in opposition, the third ear plate can be inserted into the ear plate groove between the first ear plate and the second ear plate along the axial direction C of the main support rod, and is connected through the pin shaft 120 that passes through the first ear plate, the third ear plate and the second ear plate in sequence.

[0053] Specifically, see Figure 1 In this way, the first ear plate, the third ear plate, the second ear plate and the pin 120 form a double shear structure, and the load is borne by the contact surface between the pin 120 and the first ear plate group 111 and the second ear plate group 112, respectively, which can not only realize the connection between the strut segments 110, but also have a simple structure and good force-bearing performance. In addition, the first ear plate and the second ear plate are connected to the main limb 113 through the front plate, and the third ear plate is connected to the main limb 113 through the rear plate. Since the front plate and the rear plate are both flat plates, the ear plate can be welded and positioned on the flat plate first, and then the flat plate can be welded and installed on the main limb 113, thereby improving the position accuracy of the ear plate group; and the flat plate and the main limb have a larger fitting area and more welding points, thereby improving the connection strength between the ear plate and the main limb 113.

[0054] When multiple pins 120 are coaxially arranged, they are equivalent to one pin 120. In this case, the strut segments 110 connected by the coaxially arranged pins 120 are pivotally connected, which can only withstand tension but not pressure, and thus cannot meet the requirements of attaching the strut. Therefore, the pins 120 should be arranged in a non-coaxial arrangement. In order to improve the stress performance of the attached strut, Figure 1 As shown, in the first ear plate group 111 and the second ear plate group 112 connected in alignment, the first ear plate, the third ear plate and the second ear plate are connected through a plurality of pins 120 arranged in parallel and at intervals.

[0055] Specifically, those skilled in the art can understand that, compared with the non-parallel spacing arrangement, after the multiple pins 120 arranged in parallel and spaced relation pass through the first ear plate, the third ear plate and the second ear plate, the fixed relationship between the strut segments 110 can be achieved while also strengthening the structural strength between the strut segments 110.

[0056] When the attachment brace may be subjected to a higher load, the first ear plate, the third ear plate and the second ear plate may each include at least two unit ear plates, and each unit ear plate is provided with a pin shaft hole.

[0057] Specifically, a multi-shear structure of double shear or more can be formed between the first ear plate group 111, the second ear plate group 112 and the pin shaft 120, so that the force on each unit ear plate is more uniform and the force bearing performance is better.

[0058] In this embodiment, Figure 1 As shown, the adjustable strut segment is also connected to the main strut 100 via a first ear plate group 111 and a second ear plate group 112 that are aligned and connected.

[0059] Specifically, see Figure 1 The second lug plate set 112 is provided on one end of the adjustable strut section adjacent to the main strut 100, and is axially connected to the main strut 100 through the first lug plate set 111. In this way, the main strut 100 and the adjustable strut section can be connected, the structure is simple and no additional connector is required.

[0060] Of course, a first ear plate group 111 may also be provided on one end of the adjustable strut section adjacent to the main strut 100 , and the adjustable strut section may be axially connected to the main strut 100 via a second ear plate group 112 .

[0061] In this embodiment, if Figure 1 , Figure 2 , Fig.11 and Fig.12 As shown, the adjustable support rod segment is a welding segment 200, and the welding segment 200 includes a first welding segment 210 and a second welding segment 220 for on-site welding.

[0062] Specifically, since the length of the attachment struts used for super-large tower cranes is relatively large, the screw adjustment method commonly used in the prior art cannot meet the length adjustment requirements of the adjustable strut segments. Therefore, the welding segment 200 is used as the adjustable strut segment, and the distance between the first welding segment 210 and the second welding segment 220 is adjusted to a predetermined size. After the welding segment 200 and the second welding segment 220 are welded and connected, the welding segment 200 of a predetermined length can be obtained. After the welding segment 200 is axially connected to the main strut 100, the length of the attachment struts and the distance between the tower crane and the building can be accurately matched. With such a configuration, the adjustable strut segment can meet the strength requirements, and has a simple structure, high practicality and economy.

[0063] Adjusting the distance between the first welding section 210 and the second welding section 220 to a predetermined size can be achieved in a variety of ways. In this embodiment, for example, Figure 5 and Figure 6 As shown, the first welding section 210 includes a first end plate 211 and a second end plate 212 which are arranged in parallel and spaced apart and extend along the axial direction C of the main support rod, and a receiving space is formed between the first end plate 211 and the second end plate 212; the second welding section 220 is a box beam structure which is insertable into the receiving space with adjustable length along the axial direction C of the main support rod.

[0064] Specifically, see Figure 5 and Figure 6The first end plate 211 and the second end plate 212 can both be arranged on the rectangular end plate, that is, the first end plate 211 and the second end plate 212 arranged in parallel and spaced apart are connected by a rectangular front end plate. Among them, a plurality of end plate reinforcing ribs are arranged on one side of the rectangular front end plate along the axial direction C of the main strut, and the end plate reinforcing ribs are used to strengthen the connection strength between the first end plate 211, the second end plate 212 and the rectangular front end plate. In addition, a plurality of ear plate reinforcing ribs are also arranged on the other side of the rectangular front end plate along the axial direction C of the main strut to strengthen the connection strength between the ear plate and the rectangular front end plate; see Figure 7 and Figure 8 The box beam structure consists of four flat plates connected by a rectangular rear end plate. Fig.11 A plurality of lifting ears for lifting the first welding section 210 and the second welding section 220 are also provided between the rectangular front end plate and the rectangular rear end plate, wherein the lifting ears are respectively provided on the first end plate 211 near the rectangular front end plate portion and the box beam structure near the rectangular rear end plate portion. When the second welding section 220 of the box beam structure is inserted into the receiving space to a predetermined depth along the axial direction C of the main support rod, the first welding section 210 and the second welding section 220 can be welded and connected to obtain a welding section 200 of a predetermined length. With such a configuration, the structure is simple, the material collection and processing of each component are very convenient, and it is conducive to the plug-in connection between the first welding section 210 and the second welding section 220.

[0065] In this embodiment, if Figures 5 to 11 As shown, a guide plate 230 for guiding and plugging the box beam structure is provided on the contact plate surface between the first welding section 210 and the second welding section 220 .

[0066] Specifically, see Figures 5 to 8 The guide plate 230 on the first welding section 210 abuts against both sides of the second welding section 220 and restricts the second welding section 220 from moving to both sides, so as to achieve the guidance of the box beam structure. Figures 9 to 11 A guide plate 230 is also provided on the second welding section 220, which is used to abut against the first end plate 211 to limit the movement of the second welding section 220 to both sides, further enhancing the guiding effect of the guide plug-in of the box beam structure. In this way, the straightness of the adjustable brace section can be guaranteed during the process of adjusting the brace length.

[0067] In this embodiment, if Figure 8 and Fig.10 As shown, the second welding section 220 is a tip box beam 221 suitable for being inserted into the receiving space.

[0068] like Figure 5 , Figure 8 and Fig.10As shown, the first end plate 211 and the second end plate 212 of the first welding section 210 are both tip plates, and the second welding section 220 is a tip box beam 221 suitable for inserting into the receiving space. Since the first welding section 210 and the second welding section 220 are large in size and weight and difficult to connect, such a setting can facilitate the connection between the two, and also help to increase the length of the weld and enhance the strength of the weld.

[0069] In this embodiment, if Figure 5 , Figure 6 , Fig.10 and Fig.11 As shown, the first welding section 210 further includes a U-shaped plate 250 for encircling the first end plate 211 and the second end plate 212 .

[0070] Specifically, since the first end plate 211, the second end plate 212 and the second welding section 220 are heavy, the U-shaped plate 250 can be provided to prevent the distance between the upper end plate and the lower end plate from increasing due to gravity, thereby preventing the welding quality from being affected by the size change of the first welding section 210.

[0071] The present application also discloses a new type of super large tower crane, such as Figure 1 and Figure 2 As shown, a super-large tower crane in a specific embodiment includes the above-mentioned attachment brace for super-large tower crane.

[0072] Due to the straightness and strength requirements of the attachment brace of a super-large tower crane, the above-mentioned attachment brace is more suitable for super-large tower cranes and improves the installation efficiency and safety of the attachment brace. Among them, a super-large tower crane can be defined as a tower crane type with a lifting height of more than 200 meters.

[0073] The higher the lifting height of the super-large tower crane, the longer the required attachment strut length and load will be, and the higher the straightness requirement of the attachment strut and the strength requirement of the strut segment 110 will be. Of course, the super-large tower crane is not limited to the lifting height exceeding 200 meters, and may also include the type in which the number of strut segments 110 exceeds 3, or the length of the main strut 100 exceeds 45 meters.
