It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] In the description of the embodiments of this application, unless otherwise expressly specified and limited, technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0026] In this application, the orientation or positional relationship between "first direction" and "second direction" is based on the appendix. Figure 4 The orientation or positional relationship shown is for illustrative purposes only and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application.

[0027] One embodiment of this application provides a support frame; please refer to [link / reference]. Figure 2 , Figure 3 and Figure 4 The support frame includes a lower frame 10 and an upper frame 20.

[0028] The lower frame 10 includes a first crossbeam 11, a plurality of second crossbeams 12, a first column 13, and a plurality of second columns 14. The first column 13 and the second column 14 extend along the height direction of the support frame. The second columns 14 are spaced apart along a first direction. Adjacent second columns 14 are connected by the first crossbeam 11. The first column 13 is located outside the plane formed by the second columns 14. The first column 13 and each second column 14 are connected by the second crossbeam 12. The first direction is perpendicular to the height direction.

[0029] The upper frame 20 includes a frame body 21 and a drive assembly. The drive assembly includes multiple support columns 221. The first column 13 and each of the second columns 14 are respectively provided with a support column 221 that can move along the height direction. The top of the support column 221 is connected to the frame body 21. The drive assembly is set on the lower frame 10 and is driven to the frame body 21 through the support columns 221, so that the frame body 21 and the support columns 221 move relative to the first column 13 and the second column 14.

[0030] Specifically, the first crossbeam 11 is connected to the second columns 14 spaced apart along the first direction, and the first column 13 is located outside the plane formed by the second columns 14. That is to say, the first crossbeam 11 extends along the first direction, the length direction of the first crossbeam 11 is the first direction, and the first column 13 is located on one side of the first crossbeam 11 along the width direction.

[0031] The drive component refers to the component that drives the frame body 21 and the support column 221 to move relative to the lower frame 10, and supports the frame body 21 through the support column 221.

[0032] The support column 221 refers to the component that moves along the height direction under the action of the drive component, and plays the role of transmitting driving force and supporting the main body of the frame 21.

[0033] The first column 13 and the second column 14 are each provided with a support column 221. The end of the support column 221 facing away from the lower frame 10 is connected to the frame body 21, thereby providing better support for the frame body 21 and improving the stability of the support frame.

[0034] The structural type of the support column 221 is not limited.

[0035] For example, the drive assembly includes multiple drive cylinders, each drive cylinder comprising a cylinder body and a cylinder column 223. A first column 13 and each of the second columns 14 are respectively provided with a drive cylinder, and each support column 221 is a cylinder column 223. This enables the drive assembly to provide good driving and support effects for the frame body 21.

[0036] Specifically, the driving cylinder refers to the component used to drive the frame body 21 to move and to support the frame body 21 after it reaches the set position.

[0037] The drive cylinder is set in a one-to-one correspondence with the first column 13 and the second column 14.

[0038] The cylinder column 223 is driven to the cylinder body and the frame body 21 respectively, so that the cylinder body drives the cylinder column 223 to move along the height direction, thereby driving the frame body 21 to move relative to the lower frame 10.

[0039] Of course, in other embodiments, the support column 221 may also be other structures or a combination of multiple structures.

[0040] The support frame of this embodiment includes a lower frame 10 and an upper frame 20. A first column 13 and a second column 14 extend along the height direction of the support frame. The second columns 14 are spaced apart along a first direction, and adjacent second columns 14 are connected by a first crossbeam 11. The first column 13 is located outside the plane formed by the second columns 14, and the first column 13 is connected to each of the second columns 14 by a second crossbeam 12. Each of the first column 13 and each of the second columns 14 is respectively provided with a support column 221 that can move along the height direction. The top end of the support column 221 is connected to the frame body 21. A driving assembly is disposed on the lower frame 10 and is drivenly connected to the frame body 21 through the support column 221, so that the frame body 21 and the support column 221 move relative to the first column 13 and the second column 14. Therefore, adjacent second columns 14 are connected by a first crossbeam 11, and the first column 13 is positioned outside the plane formed by all the second columns 14. Simultaneously, the first column 13 and the second column 14 are connected by a second crossbeam 12, enabling the first column and all the second columns to form a stable triangular support structure. This results in a more compact support frame structure with less space required. Furthermore, it enhances the bending resistance and stability of the support frame.

[0041] In one embodiment, please refer to Figure 2 and Figure 3 One of the first column 13 and the second column 14 has a first receiving cavity, and the other has a second receiving cavity. The driving assembly includes an auxiliary arm 222 and a driving cylinder. The driving cylinder includes a cylinder body and a cylinder column 223. The cylinder body is located in the second receiving cavity, and the cylinder column 223 can extend and retract relative to the cylinder body. Among the multiple support columns 221, some support columns 221 are cylinder columns 223, and others are auxiliary arms 222. The auxiliary arms 222 are slidably arranged in the first receiving cavity. By setting the cylinder body and the auxiliary arm 222 in the second receiving cavity and the first receiving cavity respectively, the space occupied by the support frame is reduced, making the structure more compact. On the other hand, the cylinder column 223 and the auxiliary arm 222 slide relative to the second receiving cavity and the first receiving cavity respectively to drive the frame body 21 to move, thereby improving the stability of the frame body 21 during movement.

[0042] Specifically, the first receiving cavity refers to the space that accommodates the auxiliary arm 222.

[0043] The second receiving cavity refers to the space that houses the driving cylinder.

[0044] The first column 13 may have a first receiving cavity, the second column 14 may have a second receiving cavity, the number of cylinder bodies may correspond one-to-one with the number of second columns 14, and the number of auxiliary arms 222 may correspond one-to-one with the number of first columns 13.

[0045] Alternatively, the first column 13 may have a second receiving cavity, the second column 14 may have a first receiving cavity, the number of cylinder bodies may correspond one-to-one with the number of first columns 13, and the number of auxiliary arms 222 may correspond one-to-one with the number of second columns 14.

[0046] The auxiliary arm 222 refers to a component that can move within the first receiving cavity and cooperate with the cylinder column 223 to jointly support the frame body 21.

[0047] The cylinder body of the drive cylinder is installed in the second receiving cavity. The cylinder column 223 can extend and retract under the action of the cylinder body, and the auxiliary arm 222 can slide in the first receiving cavity. Thus, when the drive cylinder is working, the extension and retraction of the cylinder column 223 causes the upper frame 20 to rise or fall, while the auxiliary arm 222 slides in the first receiving cavity, playing a role in auxiliary support and guidance, thereby improving the stability of the upper frame 20 during movement.

[0048] In one embodiment, please refer to Figure 2 The support frame also includes a locking element. The auxiliary arm 222 has a locking hole 222a, and the first column 13 has a connecting hole 13a. The locking hole 222a communicates with the connecting hole 13a, and the locking element passes through the locking hole 222a and the connecting hole 13a. This further enhances the stability of the frame body 21 during operation.

[0049] Specifically, the locking element refers to the component used to lock the auxiliary arm 222 and prevent the auxiliary arm 222 from sliding within the first receiving cavity.

[0050] The structure of the locking element is not limited.

[0051] For example, the locking element is a limit pin.

[0052] The locking hole 222a communicates with the connecting hole 13a, and the locking member passes through the locking hole 222a and the connecting hole 13a to fix the auxiliary arm 222 in a preset position, thereby fixing the frame body 21 at a preset height position.

[0053] The number of locking holes 222a is unlimited.

[0054] For example, the number of locking holes 222a is one.

[0055] For example, there are multiple locking holes 222a, so the frame body 21 can be adjusted to different heights as needed to meet the requirements of different working conditions.

[0056] In one embodiment, the support frame further includes at least one auxiliary slider located within the first receiving cavity and disposed around the outer periphery of the auxiliary arm 222. Thus, the auxiliary slider reduces the swaying and offset of the auxiliary arm 222 during movement, thereby improving the stability of the auxiliary arm 222 and consequently enhancing the bending resistance of the support frame.

[0057] Specifically, there is no limit to the number of auxiliary sliders.

[0058] For example, the number of auxiliary sliders is one.

[0059] For example, there may be multiple auxiliary sliders.

[0060] In one specific embodiment, the support frame includes a plurality of auxiliary sliders, each auxiliary slider being located within a first receiving cavity and on the outer periphery of the auxiliary arm 222, with each auxiliary slider located on the side of the auxiliary arm 222 away from the frame body 21.

[0061] In one specific embodiment, the support frame includes multiple auxiliary sliders, each of which is located within the first receiving cavity and on the outer periphery of the auxiliary arm 222. Some of the auxiliary sliders are located on the side of the auxiliary arm 222 away from the frame body 21, while the other part of the auxiliary sliders are located on the side of the auxiliary arm 222 close to the frame body 21. This further reduces the swaying and offset of the auxiliary arm 222 during movement, thereby further improving the bending resistance of the support frame.

[0062] The shape of the auxiliary slider is not limited.

[0063] For example, the auxiliary slider is circular.

[0064] For example, the auxiliary sliders are block-shaped, and each auxiliary slider is arranged at intervals along the outer periphery of the auxiliary arm 222.

[0065] The connection position of the auxiliary slider is not limited.

[0066] For example, the auxiliary slider can be attached to the wall of the first receiving cavity.

[0067] For example, the auxiliary slider can be connected to the outer periphery of the auxiliary arm 222.

[0068] In one embodiment, please refer to Figure 4 The lower frame 10 also includes a third crossbeam 15, one end of which is connected to the first column 13, and the other end is connected to the first crossbeam 11. This further enhances the stability of the support frame.

[0069] In one embodiment, please refer to Figure 2 , Figure 3 and Figure 4The support frame also includes a third column 16 extending along the height direction. The third column 16 is located on the side of the first crossbeam 11 opposite to the first column 13, and a corresponding support column 221 that can move along the height direction is provided on the third column 16. This further improves the stability and bending resistance of the support frame.

[0070] Specifically, the structural type of the third column 16 is not limited.

[0071] For example, the third column 16 has a connecting hole 13a, and the auxiliary arm 222 has a locking hole 222a. The locking hole 222a communicates with the connecting hole 13a, and a locking element passes through the locking hole 222a and the connecting hole 13a. This improves the stability of the support frame and prevents the frame body 21 from moving along the height direction during operation.

[0072] In one embodiment, please refer to Figure 1 The support frame also includes a mounting base 30 and a luffing cylinder 40. The first column 13 and the second column 14 are respectively hinged to the mounting base 30. One end of the luffing cylinder 40 is hinged to the mounting base 30, and the other end is hinged to the second column 14 to drive the lower frame 10 to rotate. Thus, by driving the second column 14 to rotate through the luffing cylinder 40, the lower frame 10 can be rotated, facilitating the adjustment of the luffing angle of the lower frame 10 and improving work efficiency.

[0073] The luffing cylinder 40 refers to the component that drives the lower frame 10 to rotate in order to adjust the luffing angle of the lower frame 10.

[0074] Mounting base 30 refers to the basic support part of the support frame, which is fixed on the ground or platform and other basic structures to fix the support frame and support the lower frame 10.

[0075] One end of the luffing cylinder 40 is hinged to the mounting base 30, allowing the luffing cylinder 40 to rotate within a certain range around the hinge point on the mounting base 30. The other end of the luffing cylinder 40 is hinged to the second column 14, which can drive the lower frame 10 to rotate, thereby allowing the lower frame 10 to be luffed to a preset position conveniently and quickly.

[0076] In one embodiment, please refer to Figure 1 The support frame also includes a limiting support 50, which includes a first hinge portion, a first connecting surface, and a second connecting surface. The limiting support 50 is disposed between the mounting base 30 and the first column 13. One of the mounting base 30 and the first column 13 is connected to the first connecting surface, while the other abuts against the second connecting surface and has a second hinge portion, which is hinged to the first hinge portion. Therefore, after the lower frame 10 changes angle to a preset angle, the limiting support 50 can restrict the angle change of the lower frame 10, thereby improving the limiting effect and thus enhancing the stability of the support frame during use.

[0077] Specifically, the limiting support 50 refers to a component that can restrict the movement of the lower frame 10. After the lower frame 10 changes amplitude to a preset angle, the limiting support 50 can position the lower frame 10 and restrict the angle change of the lower frame 10.

[0078] The amplitude angle is unlimited.

[0079] For example, the amplitude angle is 90°.

[0080] It is understandable that the mounting base 30 is connected to the first connecting surface, the first column 13 has a second hinge part, and the second column 14 abuts against the second connecting surface.

[0081] Alternatively, the first column 13 can be connected to the first connecting surface, and the mounting base 30 can have a second hinge part, with the mounting base 30 abutting against the second connecting surface.

[0082] In one embodiment, please refer to Figure 1 The support frame also includes a third column 16 extending along the height direction. The third column 16 is located on the side of the first crossbeam 11 opposite to the first column 13. The first column 13 has a first receiving cavity, the second column 14 has a second receiving cavity, and the third column 16 has a third receiving cavity. The drive assembly includes multiple auxiliary arms 222 and multiple drive cylinders, each drive cylinder corresponding to a second receiving cavity. The auxiliary arms 222 are slidably disposed within the third receiving cavity. Thus, on the one hand, by setting the drive assembly within the second receiving cavity, the drive cylinder column 223 moves to drive the frame body 21 and the auxiliary arms 222, resulting in better lifting synchronization of the drive cylinders. On the other hand, by setting the auxiliary arms 222 within the first and second receiving cavities, the stability of the frame body 21 during movement is improved, while the bending resistance of the support frame is also enhanced.

[0083] In one specific embodiment, please refer to Figure 1 The lower frame 10 includes two second columns 14, which are arranged at intervals along a first direction. The two second columns 14 are connected by a first crossbeam 11. Along a second direction, a first column 13 and a third column 16 are respectively arranged on both sides of the first crossbeam 11. The second direction is perpendicular to the first direction.

[0084] The first column 13 and each of the second columns 14 are connected by the second crossbeam 12. The two ends of the third crossbeam 15 are respectively connected to the first crossbeam 11 and the first column 13. The distance between the first column 13 and the first crossbeam 11 is greater than the distance between the third column 16 and the first crossbeam 11.

[0085] The drive assembly includes two drive cylinders and two auxiliary arms 222. The drive cylinders are disposed in the second receiving cavity, and the auxiliary arms 222 are disposed in the first receiving cavity and the third receiving cavity, respectively.

[0086] Compared to related technologies that use four hydraulic cylinders for lifting, this embodiment uses only two hydraulic cylinders, which reduces the weight of the support frame while improving the lifting synchronization during the movement of the main frame 21 driven by the hydraulic cylinders. Furthermore, by setting the first column 13 and the third column 16 along the second direction and placing the auxiliary arm 222 within the first and third receiving cavities, the bending resistance of the support frame is improved.
