Description

TECHNICAL FIELD

[0001] The present application relates to the field of mechanical adjustment and carriers, in particular to a pile driver BACKGROUND In the field of engineering construction, especially in the related industry of foundation construction, pile drivers play a very important role. With the continuous development of infrastructure construction, the application range of pile drivers is increasingly wide, covering many fields such as building engineering, bridge engineering, and water conservancy engineering. Pile drivers provide stable foundation support for various buildings by driving piles into the ground, which plays a key role in ensuring engineering quality and safety. The performance and convenience of pile drivers not only affect the progress of the project, but also relate to the cost and benefit of the entire project. In the context of modern large-scale infrastructure construction, higher and higher requirements are put forward for the efficient operation and precise operation of pile drivers.

[0002] In the traditional application of pile driving equipment, in order to meet the needs of different working conditions, when in long-distance moving scenes such as transportation, the stand is laid flat and folded up to reduce the occupied space and facilitate the handling and transfer of the equipment. When entering the working state, the stand needs to be erected and unfolded. In order to realize the conversion of the two states of the stand, various methods are usually adopted. The more common one is to use a relatively direct hoisting method, which uses large cranes and other equipment to lift the stand and place it in the appropriate position. There are also some simple mechanical devices that can be manually operated by workers to gradually adjust the angle of the stand to achieve the desired state. In some cases, some simple hydraulic systems are used, but the function is relatively single, and the control precision and efficiency are limited. These methods can solve the problem of stand state conversion to some extent, but each has different limitations.

[0003] Due to the length of the stand itself, the long length of the stand during the conversion process between laying flat and erecting results in a large conversion stroke. The traditional hoisting method relies on external large equipment, which not only has high cost, but also is more limited by site conditions during the long-stroke conversion process, and is difficult to operate in some narrow or special terrain environments.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] Referring to Figure 1 , the present application discloses a pile driver, which comprises a base 0 and a multi-stage lifting mechanism connected to the base 0.

[0033] When the pile driver is transported, the multi-stage lifting mechanism is retracted.

[0034] When the pile driver is under construction, the multi-stage lifting mechanism is deployed.

[0035] The multi-stage lifting mechanism is applied to the pile driver, and the accurate and flexible angle adjusting function of the multi-stage lifting mechanism is used to solve the problem of the column of the pile driver in the transportation and working state conversion. The horizontal rotation axis arrangement meets the actual use requirement of the pile driver and the like, and can better realize the flattening and vertical operation of the column.

[0036] Referring to Figure 1 and Figure 2 , the multi-stage lifting mechanism comprises a base 1, a rotating piece 2, a supporting piece 3, a short driving cylinder 4 and a long driving cylinder 5.

[0037] The base 1 is connected to a chassis 0. One end of the rotating piece 2 is rotationally connected to one end of the base 1, and the rotation axis L0 of the rotating piece 2 is horizontal.

[0038] In the drawings: the rotating piece 2 comprises a column, and the column can be used to mount a vibration hammer and the like.

[0039] Referring to Figure 2 and Figure 3 , the supporting piece 3 is used to slide or roll against the rotating piece 2. In this embodiment: the supporting piece 3 is used to roll against the rotating piece 2.

[0040] The supporting piece 3 comprises a supporting frame 31 and a supporting wheel 32. One end of the supporting frame 31 is rotationally connected to the base 1, and the rotation axis L11 of the supporting frame 31 is parallel to the rotation axis L0. The supporting wheel 32 is rotationally connected to the other end of the supporting frame 31, and the rotation axis L12 of the supporting wheel 32 is parallel to the rotation axis L0. The outer periphery of the supporting wheel 32 is used to roll against the rotating piece 2.

[0041] In the drawings: the supporting frame 31 is in the shape of a trapezoid, and the trapezoid is rotationally connected to the base 1 at the lower base; and the supporting wheel 32 is rotationally connected to the upper base of the trapezoid.

[0042] The rotating piece 2 is provided with an embedding groove 21, and the embedding groove 21 is used for the supporting wheel 32 to extend into. The groove bottom of the embedding groove 21 is provided with a contact surface 22, and the contact surface 22 is used for the outer periphery of the supporting wheel 32 to roll against.

[0043] In the drawings: the rotating piece 2 comprises a channel steel, and the channel steel is connected to the surface of the column, and the channel steel forms the embedding groove 21.

[0044] Both ends of the short driving cylinder 4 are rotationally connected to the base 1 and the supporting frame 31 respectively; the rotation axis L21 between the short driving cylinder 4 and the base 1 and the rotation axis L22 between the short driving cylinder 4 and the other end of the supporting frame 31 are both parallel to the rotation axis L0. Meanwhile, the rotation axis L11, the rotation axis L12, the rotation axis L21 and the rotation axis L22: any three of them are not coplanar.

[0045] The piston rod of the short driving cylinder 4 is extended and retracted to drive the rotating member 2 to rotate in the range of [0, A] through the support member 3.

[0046] It should be noted that the box at the rightmost side in the drawing is detachable, such as counterweight, etc. Before rotating the rotating member 2 to be horizontal, the box at the rightmost side can be removed first.

[0047] Referring to Figure 1 , the two ends of the long driving cylinder 5 are connected to the base 1 and the rotating member 2 respectively, and at the same time, the long driving cylinder 5 is in a floating state when the short driving cylinder 4 works to make the rotating member 2 rotate.

[0048] Specifically: when the long driving cylinder 5 is in a floating state, the pipeline of the long driving cylinder 5 is always open; the long driving cylinder 5 is directly connected to the oil tank, and the hydraulic oil can freely enter and exit the long driving cylinder 5; for example, the pipeline of the long driving cylinder 5 is connected to the oil tank and the working pipeline through a two-position electromagnetic valve; the working state one of the two-position electromagnetic valve is that the pipeline of the long driving cylinder 5 is directly connected to the oil tank (i.e. the pipeline of the long driving cylinder 5 is always open, the long driving cylinder 5 is in a floating state, and the piston rod of the long driving cylinder 5 is extended and retracted with the rotation of the rotating member 2); the working state two of the two-position electromagnetic valve is that the pipeline of the long driving cylinder 5 is connected to the working pipeline, and then the piston rod of the long driving cylinder 5 is controlled to extend and retract through the working pipeline to drive the rotating member 2 to rotate.

[0049] The piston rod of the long driving cylinder 5 is actively extended and retracted to make the rotating member 2 rotate in the range of [A, 90°]. It should be noted that when the rotating member 2 rotates in the range of (A, 90°], the contact surface 22 is separated from the support wheel 32.

[0050] The long driving cylinder 5 is provided with two. In the direction parallel to the rotation axis L0, the two long driving cylinders 5 are located on the two sides of the rotating member 2, and the two long driving cylinders 5 are mirror-symmetric.

[0051] In the drawing: the distance between the two long driving cylinders 5 increases as it approaches the base 1.

[0052] At the same time, referring to Figure 4 and Figure 5 , the multi-stage lifting mechanism further comprises a connecting assembly 6. Corresponding to each long driving cylinder 5: the connecting assembly 6 is provided with two, and the two ends of the long driving cylinder 5 are connected to the base 1 and the rotating member 2 through the connecting assembly 6 respectively.

[0053] The connecting assembly 6 comprises a connecting piece 61 and a connecting shaft 62. The connecting piece 61 is provided with two, and the two connecting pieces 61 are both rotationally connected to the connecting shaft 62, and the rotation axes of the two connecting pieces 61 intersect or are in different planes. One connecting piece 61 is used to be connected to the long driving cylinder 5, and the other connecting piece 61 is used to be connected to the base 1 or the rotating member 2.

[0054] In the drawings: the rotation axes of the two connecting members 61 are respectively parallel to the rotation axis L0 and perpendicular to the rotation axis L0.

[0055] In the application of the pile driver, the rotating member 2 can be a column of the pile driver. When the pile driver is in a transportation state, the pile driver places and folds the column through the cooperation of the short driving cylinder 4 and the long driving cylinder 5, reduces the overall height and occupied space of the pile driver, and facilitates transportation. When the pile driver reaches the working site and enters the working state, the pile driver works again to stand up and unfold the column, thereby preparing for subsequent pile driving operations. In this process, the pile driver accurately controls the rotation angle of the column, thereby improving the use convenience and working efficiency of the pile driver.

[0056] The multi-stage lifting mechanism further comprises a detection control module.

[0057] The detection control module is configured to detect the state between the support member 3 and the rotating member 2, detect the angle of the rotating member 2, receive an operation signal, and control the two-position electromagnetic valve.

[0058] For example, the detection control module comprises a pressure sensor. When the support member 3 supports the rotating member 2, the pressure sensor outputs a pressure signal, and the detection control module judges that the support member 2 and the rotating member 3 are pressed against each other. The detection control module further comprises a travel switch. The travel switch is configured to detect the relative displacement between the support member 2 and the rotating member 3. When the piston rod of the short driving cylinder 4 is extended to the maximum length, the rotating member 2 is rotated to A, the travel switch is triggered to output an angle signal, and the detection control module judges that the rotating member 2 is rotated to A. The detection control module is further configured to be connected to an operation button. When a person presses the operation button, the detection control module receives an operation signal.

[0059] When the pressure signal, the angle signal and the operation signal are received, the detection control module controls the two-position electromagnetic valve to switch between the working states, i.e., controls the long driving cylinder 5 to switch between the floating state and the working state. When the pressure signal is received and the angle signal is not received, whether the operation signal is received or not, the detection control module controls the two-position electromagnetic valve to be in the working state I, i.e., controls the long driving cylinder 5 to be in the floating state.

[0060] The implementation principle of the pile driver according to the embodiment of the application is the step-by-step driving mode of the multi-stage lifting mechanism, which overcomes the shortcomings of the traditional adjustment mode, improves the adaptability and working efficiency of the equipment under different working conditions, reduces the labor intensity of the operator and the operation cost of the equipment, and has important significance for improving the overall performance of the engineering machinery equipment.

[0061] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
