Description

Technical Field

[0001] This utility model relates to the field of cranes, and in particular to a crane with a stable support function. Background Technology

[0002] In modern engineering construction and freight transportation, cranes, as key lifting equipment, are widely used in various industries such as building construction, port loading and unloading, and mining. Traditional cranes typically rely on their own support structure for stability during operation. However, the support range of existing structures is often fixed, making it difficult to flexibly adjust them according to different working scenarios and load requirements, thus limiting the crane's applicability and work efficiency.

[0003] Therefore, it is necessary to provide a new type of crane with stable support function to solve the above-mentioned technical problems. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a crane with stable support function is provided to solve the above-mentioned problems.

[0005] The crane with stable support function provided by this utility model includes: a support base; a support column is installed on the top of the support base, and a crane is installed on the top of the support column; wherein, support components are arranged around the support base, and the support components can reduce the local pressure of the crane on the support base; an adjustment component is arranged inside the support base, which can make the support components reciprocate, so as to adjust the support range of the support components according to actual working needs.

[0006] Preferably, the support assembly includes an outer support cylinder connected to the support base on all four sides, and an inner support cylinder is slidably connected to the inner side of the end of each outer support cylinder away from the support base. A support platform is connected to the end of each inner support cylinder away from the support base. Multiple guide columns are equidistantly connected to the outer side of each inner support cylinder. A guide groove for sliding of the guide columns is opened on the inner side of each outer support cylinder.

[0007] Preferably, the support assembly further includes a support top seat installed on the outer top of the support column, with support outer rods rotatably connected to all four sides of the support top seat, and support inner rods rotatably connected to the top of each support platform, with the outer top of the support inner rod sliding against the inner bottom of the support outer rod.

[0008] Preferably, the adjustment assembly includes an active bevel gear rotatably connected to the inner top wall of the support base, driven bevel gears meshing around the bottom of the active bevel gear, a transmission rod connected to the side of each driven bevel gear away from the active bevel gear, and a drive component for driving the active bevel gear to rotate is installed at the bottom of the support column.

[0009] Preferably, the end of each transmission rod away from the driven bevel gear passes through the inner wall of the support base and is connected to a threaded rod, and the threaded rod is located inside the inner cylinder of the support. The outer side of the threaded rod is connected to the inner side of the inner cylinder of the support through a threaded transmission.

[0010] Preferably, the inner perimeter of the support base is equipped with reinforcing rods.

[0011] Compared with related technologies, the crane with stable support function provided by this utility model has the following beneficial effects:

[0012] This invention, through the design of the adjustment component, enables the support component to reciprocate according to actual working needs. Through the cooperation of the active bevel gear, driven bevel gear, transmission rod, and threaded rod, the position of the inner cylinder of the support is precisely adjusted, thereby changing the support range of the support component.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0021] This utility model provides a crane with stable support function, which includes: a support base 1; a support column 11 is installed on the top of the support base 1, and a crane 12 is installed on the top of the support column 11; wherein, support components are arranged around the support base 1, and the support components can reduce the local pressure of the crane on the support base 1; an adjustment component is arranged inside the support base 1 to enable the support components to reciprocate, so as to adjust the support range of the support components according to the actual working needs; and reinforcing rods 13 are installed on the inner four sides of the support base 1.

[0022] It should be noted that: the support base 1, as the fundamental component of the entire crane, bears the support column 11 above, the crane 12, and the pressure generated by the crane during operation, transmitted through the support assembly. It provides a stable foundation for the crane, ensuring its overall stability during operation. The support column 11 is installed on top of the support base 1, connecting the support base 1 and the crane 12, transmitting the weight of the crane 12 and the forces generated during operation to the support base 1. The crane 12 is the core working component of the equipment, used for lifting, handling, and other operations. It performs tasks such as grabbing, lifting, and moving heavy objects through its mechanical structure and power system. The support assembly is located around the support base 1. Its main function is to distribute the local pressure of the crane on the support base 1. By increasing the contact area with the ground, it evenly distributes the pressure generated by the crane during operation onto the ground, reducing excessive pressure on any local area of ​​the support base 1. This improves the stability and safety of the crane during operation and prevents damage to the support base 1 or the ground due to excessive local pressure. The adjustment assembly is located within the support base 1. Its function is to allow the support assembly to reciprocate, adjusting its support range according to actual working requirements. When the crane operates under different conditions or loads, the position of the support assembly can be changed via the adjustment assembly, allowing it to better adapt to the working environment and further enhancing the crane's stability. Reinforcing rods 13 are installed around the inner perimeter of the support base 1. Their main function is to enhance the structural strength and stability of the support base 1. During crane operation, the support base 1 bears various forces from the crane and the support assembly. The reinforcing rods 13 can distribute these forces, preventing deformation or damage to the support base 1 due to uneven stress, thus ensuring the stable operation of the entire crane.

[0023] In an embodiment of this utility model, the support assembly includes an outer support cylinder 2 connected to the support base 1 on all four sides. An inner support cylinder 21 is slidably connected to the inner side of the end of each outer support cylinder 2 away from the support base 1. A support platform 22 is connected to the end of each inner support cylinder 21 away from the support base 1. A plurality of guide columns 23 are equidistantly connected to the outer side of each inner support cylinder 21. A guide groove for sliding of the guide columns 23 is opened on the inner side of each outer support cylinder 2. The support assembly also includes a support top seat 24 installed on the top of the outer side of the support column 11. An outer support rod 25 is rotatably connected to the four sides of the support top seat 24. An inner support rod 26 is rotatably connected to the top of each support platform 22. The top of the outer side of the inner support rod 26 slides on the bottom of the inner side of the outer support rod 25.

[0024] It should be noted that the outer support cylinder 2 is connected to the support base 1 on all four sides and is an important component of the support assembly. It provides a sliding outer shell structure for the inner support cylinder 21, guiding and protecting it. It also connects the support base 1 to the inner support cylinder 21, allowing the entire support assembly to work together to distribute the pressure of the crane on the support base 1. Furthermore, the guide groove on its inner side cooperates with the guide column 23 to ensure the stability and straightness of the sliding of the inner support cylinder 21. The support platform 22 is connected to the end of each inner support cylinder 21 furthest from the support base 1 and is the component that contacts the ground. It increases the contact area between the support assembly and the ground, allowing the support assembly to more effectively and evenly transmit the crane's pressure to the ground, reducing pressure on the ground and preventing damage. Simultaneously, the support platform 22 also provides a rotating base for the inner support rod 26, allowing it to rotate and adjust its position using it as a fulcrum. The support top seat 24 is installed on the outer top of the support column 11 and is an important component connecting the outer support rod 25. It provides a pivot point for the outer support rod 25, allowing the outer support rod 25 to rotate around the support top seat 24, thereby adjusting the angle and position of the outer support rod 25.

[0025] In an embodiment of this utility model, the adjustment component includes an active bevel gear 3 rotatably connected to the inner top wall of the support base 1. Driven bevel gears 31 are meshed around the bottom of the active bevel gear 3. A transmission rod 32 is connected to the side of each driven bevel gear 31 away from the active bevel gear 3. A driving component for driving the active bevel gear 3 to rotate is installed at the bottom of the support column 11. The end of each transmission rod 32 away from the driven bevel gear 31 passes through the inner wall of the support base 1 and is connected to a threaded rod 33. The threaded rod 33 is located inside the inner cylinder 21 of the support, and the outer side of the threaded rod 33 is connected to the inner side of the inner cylinder 21 of the support through a threaded transmission.

[0026] It should be noted that the driving bevel gear 3 is rotatably connected to the inner top wall of the support base 1, and it is the starting component for power transmission of the adjustment assembly. Under the action of the driving component, it can rotate, transmitting the power generated by the driving component to the driven bevel gear 31 that meshes with it, thereby driving the entire adjustment assembly to work and adjusting the support range of the support assembly. The driving component is an electric motor mounted at the bottom of the support column 11, used to drive the driving bevel gear 3 to rotate. Multiple driven bevel gears 31 are meshed with the bottom of the driving bevel gear 3 around its perimeter. When the driving bevel gear 3 rotates, it drives the driven bevel gears 31 to rotate through the meshing action between their teeth. The driven bevel gears 31 change the direction of power transmission, transmitting the rotational power of the driving bevel gear 3 to the transmission rod 32, providing power for subsequent adjustment of the support assembly. The main function of the transmission rod 32 is to transmit the rotation of the driven bevel gear 31 to the threaded rod 33. The transmission rod 32 penetrates the inner wall of the support base 1, establishing a bridge for power transmission between the inside and outside of the support base 1, ensuring that power can be transmitted from inside the support base 1 to the external support assembly. The threaded rod 33 is connected to the end of the transmission rod 32 away from the driven bevel gear 31 and is located inside the inner support cylinder 21. Its outer side is connected to the inner side of the inner support cylinder 21 via a threaded drive. When the transmission rod 32 drives the threaded rod 33 to rotate, the inner support cylinder 21 will move linearly along the axial direction of the threaded rod 33 due to the effect of the threaded drive. This allows the inner support cylinder 21 to slide within the outer support cylinder 2, thereby adjusting the support range of the support assembly to adapt to different working scenarios.

[0027] The working principle of the crane with stable support function provided by this utility model is as follows: When the crane needs to operate, the drive component installed at the bottom of the support column 11 is activated first, according to the actual working scene and load requirements. The drive component drives the active bevel gear 3 to rotate, and the active bevel gear 3 meshes with the driven bevel gears 31 around it, transmitting power to the driven bevel gears 31, causing the driven bevel gears 31 to rotate. When the driven bevel gears 31 rotate, they drive the transmission rod 32 connected to them to rotate. The transmission rod 32 passes through the inner wall of the support base 1, transmitting the rotational power to the threaded rod 33. Since the threaded rod 33 is connected to the inner support cylinder 21 through a threaded transmission, when the threaded rod 33 rotates, the inner support cylinder 21 will move linearly along the axial direction of the threaded rod 33, and slide within the outer support cylinder 2. While the inner support cylinder 21 extends and retracts, it drives the support platform 22 connected to its end to move, thereby adjusting the support range of the support assembly. During the adjustment of the support assembly, the guide post 23 on the outer side of the inner support cylinder 21 slides within the guide groove on the inner side of the outer support cylinder 2, ensuring the stability and straightness of the sliding of the inner support cylinder 21. Simultaneously, the outer support rod 25 rotatably connected around the support top seat 24, and the inner support rod 26 rotatably connected to the top of the support platform 22, will change the shape and angle of the triangular support structure through their own rotation and relative sliding as the inner support cylinder 21 moves and the support range is adjusted, adapting to different support requirements and ensuring the crane remains stable after the support range is adjusted. Once the support assembly is adjusted to the appropriate support range, the crane 12 can perform lifting, transporting, and other operations. During operation, the support assembly evenly distributes the pressure generated by the crane 12 to the ground, while the reinforcing rod 13 strengthens the structural strength of the support base 1, jointly ensuring the stable operation of the crane.
