Abstract
Description
Technical Field
[0001] This application relates to the field of mechanical adjustment and vehicles, and in particular to a multi-stage lifting structure and vehicle. Background Technology
[0002] In the field of engineering construction, especially in foundation construction, pile drivers play a crucial role. With the continuous development of infrastructure construction, the application scope of pile drivers has become increasingly widespread, covering many fields such as building construction, bridge engineering, and water conservancy projects. By driving piles into the ground, pile drivers provide stable foundation support for various structures, playing a key role in ensuring project quality and safety. The performance and ease of use of pile drivers not only affect the progress of the project but also relate to the overall project cost and benefits. In the context of modern large-scale infrastructure construction, increasingly higher demands are placed on the efficient operation and precise control of pile drivers.
[0003] In traditional piling equipment applications, to meet different working conditions, the columns are laid flat and stowed during long-distance transport to reduce space occupation and facilitate equipment handling and relocation. When entering the working state, the columns need to be erected and unfolded. Several methods are typically used to achieve this transition. A common method is direct hoisting, using large cranes or similar equipment to lift the columns and place them in the appropriate position. Other methods involve manually operating simple mechanical devices to gradually adjust the column angle to achieve the desired state. In some cases, simple hydraulic systems are used, but these have relatively limited functionality, control precision, and efficiency. These methods address the column state transition to some extent, but each has its own limitations.
[0004] Because the column itself has a certain length, its long length results in a large conversion stroke during the conversion process of laying it flat and erecting it. Traditional hoisting methods rely on large external equipment, which is not only costly, but also more restricted by site conditions during long-stroke conversion, and is even more difficult to operate in some narrow or special terrain environments. Utility Model Content
[0005] In order to complete the rotation of large components, this application provides a multi-stage lifting structure and carrier.
[0006] The multi-stage lifting structure and vehicle provided in this application adopt the following technical solution: Firstly, this application provides a multi-stage lifting structure, employing the following technical solution: A multi-stage lifting structure includes a base, a rotating component, a support component, a short drive cylinder, and a long drive cylinder. The rotating component is rotatably connected to the base. The support member is used to slide or roll against the rotating member. The two ends of the short drive cylinder are respectively connected to the base and the support member. The short drive cylinder works to make the rotating member rotate within the range of [0, A]. The long drive cylinder is connected at both ends to the base and the rotating component respectively. The long drive cylinder works to make the rotating component rotate within the range of [A, 90°]. When the short drive cylinder operates to cause the rotating component to rotate, the long drive cylinder is in a floating state.
[0007] By adopting the above technical solution, the rotation adjustment of the rotating part within different angle ranges can be achieved. The short drive cylinder causes the rotating part to rotate within the range of [0, A], while the long drive cylinder causes it to rotate within the range of [A, 90°]. Furthermore, the long drive cylinder is in a floating state while the short drive cylinder is working, avoiding mutual interference and ensuring smooth multi-stage adjustment. By utilizing the cooperation of the short-stroke short drive cylinder and the long-stroke long drive cylinder, the rotation of the rotating part within the range of [0, 90°] can be achieved.

[0009] By adopting the above technical solution, when the pipeline of the long drive cylinder is normally open, hydraulic oil can freely enter and exit the long drive cylinder, allowing the piston rod of the long drive cylinder to freely extend and retract. During the rotation of the rotating component within the range [0, A], the piston rod of the long drive cylinder extends and retracts with the rotation of the rotating component, avoiding interference with the short drive cylinder. Preferably, there are two long drive cylinders; Along a direction parallel to the rotation axis of the rotating component, the two long drive cylinders are located on both sides of the rotating component, and the two long drive cylinders are mirror-symmetrical.

The connector is provided in two parts, both of which are rotatably connected to the connecting shaft. The rotation axes of the two connectors may intersect or be out of plane. One of the connectors is used to connect to the long drive cylinder, and the other connector is used to connect to the base or rotating component.
[0014] By adopting the above technical solution, the connecting component can be adapted to long drive cylinders, especially when the long drive cylinder is not perpendicular to the rotation axis of the rotating part.
[0015] Preferably, the rotating component has a contact surface for the support component to abut against.
[0016] By adopting the above technical solution, the support component can be stably slid or roll against the rotating component, ensuring the stability of the rotating component when the short drive cylinder pushes it to rotate within the range of [0, A].
[0017] Preferably, the rotating member is provided with a groove for the support member to extend into.
[0018] By adopting the above technical solution, the support component can stably abut against the contact surface, ensuring the stability of the rotating component when the short drive cylinder pushes it to rotate within the range of [0, A].
[0019] Preferably, the support member includes a support frame. One end of the support frame is rotatably connected to the base. The two ends of the short drive cylinder are rotatably connected to the base and the support frame, respectively.
[0020] By adopting the above technical solution, the rotation of the support relative to the base, in conjunction with the operation of the short drive cylinder, makes the rotating part rotate more stably and accurately within the range of [0, A].
[0021] Preferably, the support member further includes support wheels. The support wheel is rotatably connected to the support frame, and the outer circumference of the support wheel is used to abut against the rotating component.
[0022] By adopting the above technical solution, friction is reduced, and the rotation adjustment of rotating parts is achieved more smoothly.
[0023] Secondly, this application provides a vehicle that adopts the following technical solution: A vehicle comprising the aforementioned multi-stage lifting structure, wherein the rotation axis of the rotating component is horizontal.
[0024] By adopting the above technical solution, the vehicle is equipped with a multi-stage lifting structure, which can realize the function of adjusting the angle of the rotating parts. Moreover, the horizontal rotation axis of the rotating parts can meet the switching between flattening and vertical standing, adapting to different working conditions of transportation and construction.
[0025] In summary, this application includes at least one of the following beneficial technical effects: 1.

Detailed Implementation
[0032] The present application will be further described in detail below with reference to the accompanying drawings.
[0033] Reference Figure 1 This application discloses a vehicle, including a chassis 0 and a multi-stage lifting structure connected to the chassis 0.
[0034] When the vehicle is in transit, the multi-stage lifting structure retracts.
[0035] When the vehicle is carrying out construction, the multi-stage lifting structure is deployed.
[0036] The implementation principle of a carrier according to an embodiment of this application is as follows: a multi-stage lifting structure is applied to the carrier, and its precise and flexible angle adjustment function solves the problem of switching between transportation and working states for components such as pile driver columns. The horizontal rotation axis setting meets the actual use requirements of equipment such as pile drivers, and can better realize the leveling and erection operations of the column.
[0037] Reference Figure 1 and Figure 2 This application also discloses a multi-stage lifting structure, including a base 1, a rotating component 2, a support component 3, a short drive cylinder 4, and a long drive cylinder 5.
[0038] Base 1 is connected to chassis 0. One end of rotating component 2 is rotatably connected to one end of base 1, and the rotation axis L0 of rotating component 2 is horizontal.
[0039] In the attached diagram: Rotating component 2 includes a column, which can be used to mount tools such as vibratory hammers.
[0040] Reference Figure 2 and Figure 3 The support member 3 is used to slide or roll against the rotating member 2. In this embodiment: the support member 3 is used to roll against the rotating member 2.
[0041] The support member 3 includes a support frame 31 and a support wheel 32. One end of the support frame 31 is rotatably connected to the base 1, and the rotation axis L11 of the support frame 31 is parallel to the rotation axis L0. The support wheel 32 is rotatably connected to the other end of the support frame 31, and the rotation axis L12 of the support wheel 32 is parallel to the rotation axis L0. The outer circumference of the support wheel 32 is used for rolling contact with the rotating member 2.
[0042] In the attached diagram: the support frame 31 is trapezoidal, and the lower base of the trapezoid is rotatably connected to the base 1; the support wheel 32 is rotatably connected to the upper base of the trapezoid.
[0043] The rotating component 2 is provided with a groove 21, into which the support wheel 32 extends. The bottom of the groove 21 is provided as a contact surface 22, which is used for the outer circumference of the support wheel 32 to roll against it.
[0044] In the attached figure: the rotating component 2 includes a channel steel, which is connected to the surface of the column and forms a groove 21.
[0045] The two ends of the short drive cylinder 4 are rotatably connected to the base 1 and the support frame 31, respectively. The rotation axis L21 between the short drive cylinder 4 and the base 1, and the rotation axis L22 between the other end of the short drive cylinder 4 and the support frame 31, are all rotated along the axis L0. At the same time, any three of the rotation axes L11, L12, L21, and L22 are not coplanar.
[0046] The piston rod of the short drive cylinder 4 extends and retracts to drive the rotating member 2 to rotate within the range of [0, A] via the support member 3.
[0047] It should be noted that the rightmost box in the attached diagram is detachable, such as the counterweight; the rightmost box can be removed before rotating the rotating part 2 to a horizontal position.
[0048] Reference Figure 1 The two ends of the long drive cylinder 5 are connected to the base 1 and the rotating part 2 respectively. At the same time, when the short drive cylinder 4 works to make the rotating part 2 rotate, the long drive cylinder 5 is in a floating state.
[0049] Specifically: When the long drive cylinder 5 is in a floating state, the pipeline of the long drive cylinder 5 is normally open; the long drive cylinder 5 is directly connected to the oil tank, and hydraulic oil can freely enter and exit the long drive cylinder 5; for example, the pipeline of the long drive cylinder 5 is connected to the oil tank and the working pipeline through a two-position solenoid valve; the working state 1 of the two-position solenoid valve is that the pipeline of the long drive cylinder 5 is directly connected to the oil tank (that is, the pipeline of the long drive cylinder 5 is normally open, the long drive cylinder 5 is in a floating state, and the piston rod of the long drive cylinder 5 extends and retracts with the rotation of the rotating part 2); the working state 2 of the two-position solenoid valve is that the pipeline of the long drive cylinder 5 is connected to the working pipeline, and the piston rod of the long drive cylinder 5 is controlled to extend and retract through the working pipeline to drive the rotating part 2 to rotate.
[0050] The piston rod of the long drive cylinder 5 actively extends and retracts to allow the rotating member 2 to rotate within the range of [A, 90°]. It should be noted that when the rotating member 2 rotates within the range of (A, 90°), the contact surface 22 disengages from the support wheel 32.
[0051] Two long drive cylinders 5 are provided. Along the direction parallel to the rotation axis L0, the two long drive cylinders 5 are located on both sides of the rotating part 2, and the two long drive cylinders 5 are mirror symmetrical.
[0052] In the attached diagram: the distance between the two long drive cylinders 5 increases as they approach the base 1.
[0053] At the same time, refer to Figure 4 and Figure 5 The multi-stage lifting structure also includes a connecting assembly 6. For each long drive cylinder 5, there are two connecting assemblies 6, and both ends of the long drive cylinder 5 are respectively connected to the base 1 and the rotating part 2 through the connecting assembly 6.
[0054] The connecting assembly 6 includes a connector 61 and a connecting shaft 62. Two connectors 61 are provided, both rotatably connected to the connecting shaft 62. The rotation axes of the two connectors 61 intersect or are not in the same plane. One connector 61 is used to connect to the long drive cylinder 5, and the other connector 61 is used to connect to the base 1 or the rotating component 2.
[0055] In the attached diagram: the rotation axes of the two connecting parts 61 are parallel to the rotation axis L0 and perpendicular to the rotation axis L0, respectively.
[0056] In piling machine applications, the rotating component 2 can be the piling machine's column. When the piling machine is in transport mode, the multi-stage lifting structure, through the cooperation of the short drive cylinder 4 and the long drive cylinder 5, flattens and retracts the column, reducing the overall height and space occupied by the piling machine, facilitating transportation. When the piling machine arrives at the work site and enters working mode, the multi-stage lifting structure works again, erecting and unfolding the column to prepare for subsequent piling operations. During this process, the multi-stage lifting structure precisely controls the rotation angle of the column, improving the ease of use and work efficiency of the piling machine.
[0057] The implementation principle of the multi-stage lifting structure in this application embodiment is as follows: the graded driving method of the multi-stage lifting structure overcomes the shortcomings of the traditional adjustment method, improves the adaptability and working efficiency of the equipment under different working conditions, reduces the labor intensity of operators and the operating cost of the equipment, and is of great significance for improving the overall performance of engineering machinery equipment.
[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
