Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pile drivers, in particular to a vibration pile driving device for an excavator. Background Art
[0002] A pile driver is a type of pile-driving machine that uses the power of an excavator, its own weight, and the weight of the pile to drive the pile into the ground. The completion of the pile driving work requires the coordinated movement of the various working arms of the excavator, which is a spatial combination movement. However, in the actual pile driving process, as the depth of the pile penetrating into the stratum continues to increase, the position of the end working arm is also constantly changing, causing the spatial angle between the end working arm and the pile in the vertical plane to constantly change. This requires constantly changing the angles of the various working arms of the excavator so that the pile driver is always perpendicular to the pile head in the vertical plane. However, in the spatial combination movement of the various working arms of the excavator, it is difficult to match the position and force angle of the pile driving tool connected to the end working arm with the end working arm at the same time. In particular, the farther the pile driving position is from the main excavator, the greater the visual error of the operator and the greater the difficulty of operation. This increases the difficulty of the pile driving work and the pile driving efficiency is low. Utility Model Content

In order to provide a deep understanding of the present invention, the following description will include many specific details. The present invention can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description. It should be noted that, in the absence of conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.
[0035] See also Figure 1-4 The utility model provides a vibration pile driving device for an excavator, comprising a mounting frame 1 extending in a vertical direction, the mounting frame 1 being provided with a vertical moving mechanism 2 and a connecting mechanism 4, and also comprising a vibration impact mechanism 3 connected to the vertical moving mechanism 2; the vertical moving mechanism 2 comprises a lifting cylinder 21, a vertical sliding assembly 22 and a connecting member 23, the vertical sliding assembly 22 being arranged around the mounting frame 1 and in contact with the surface of the mounting frame 1, the connecting member 23 being detachably connected to the vertical sliding assembly 22, the connecting member 23 being detachably connected to the cylinder body of the lifting cylinder 21 through a first fastener 24 and a second fastener 25 arranged at intervals, a boss 26 being provided on the cylinder body between the first fastener 24 and the second fastener 25, the vibration impact mechanism 3 comprising an impact cylinder 31 and an impact head 32.
[0036] Specifically, the lifting cylinder 21 drives the connecting member 23 to move in the vertical direction through the first fastener 24 and the second fastener 25, thereby driving the vibration impact mechanism 3 to move up and down. When the vibration pile driving device is installed on the working arm of the excavator, the impact head 32 can achieve vibration impact on the pile head, thereby continuously penetrating the pile head into the formation.
[0037] The mounting frame 1 includes a bottom bracket 11 and a first square tube bracket 12 and a second square tube bracket 13 which are arranged on the bottom bracket 11 and extend in the vertical direction, so as to facilitate the installation and movement of the vertical moving mechanism.
[0038] like Figure 6As shown, the vertical sliding assembly 22 includes a first slide plate 221, a second slide plate 222, a third slide plate 223 and a fourth slide plate 224. The first slide plate 221, the second slide plate 222, the third slide plate 223 and the fourth slide plate 224 are respectively in contact with the side surfaces of the first square tube bracket 12 to support the relative sliding of the vertical sliding assembly 22 and the first square tube bracket 12. The contact parts are respectively set as the detachable first slide plate 221, the second slide plate 222, the third slide plate 223 and the fourth slide plate 224, so as to facilitate their disassembly and replacement after wear; of course, the first slide plate 221, the second slide plate 222, the third slide plate 223 and the fourth slide plate 224 are made of wear-resistant materials and have a small friction coefficient to reduce friction, facilitate movement on the first square tube bracket 12, and improve service life.
[0039] Alternatively, if Figure 5 As shown, the connecting member 23 includes a U-shaped connecting plate 231 and a cover plate 232, and the U-shaped connecting plate 231 and the cover plate 232 are detachably connected, preferably bolted; the U-shaped connecting plate and the first slide plate 221, the second slide plate 222, and the third slide plate 223 are detachably connected, and the cover plate 232 and the fourth slide plate 224 are detachably connected, preferably bolted. Through the design of the U-shaped connecting plate 231 and the cover plate 232, the connection between the vertical sliding assembly 22 and the lifting cylinder 21 is realized. During assembly, the cover plate 232 is not installed first, so that the U-shaped connecting plate 231 can be inserted into the first square tube bracket 12, and then the cover plate 232 is fixed, which is convenient for the disassembly and replacement of the vertical sliding assembly 22 on site.
[0040] The connecting mechanism 4 is disposed on the second square tube bracket 13 , and the connecting mechanism 4 is used to install the vibration pile driving device on an excavator.
[0041] Optionally, the lifting cylinder 21 includes a cylinder barrel 211 and a piston rod 212, and a connecting rib 14 is also provided on the bottom bracket 11. The connecting rib 14, the first square tube bracket 12, and the second square tube bracket 13 are arranged in sequence at intervals, and a through hole is provided on the connecting rib 14. The connecting rib 14 is hinged to the piston rod 212 through the through hole to realize the rotation of the lifting cylinder 21, so that the lifting cylinder 21 can be tilted down in a direction away from the first square tube bracket 12, thereby away from the first square tube bracket 12 to facilitate the disassembly and installation of the connecting piece 23 and the vertical sliding assembly 22, and also facilitate the disassembly and installation of the first fastener 24 and the second fastener 25.
[0042] It also includes a first side plate 5 and a second side plate 6. The first side plate 5 and an open end of the U-shaped connecting plate 231 and the impact cylinder 31 are both detachably connected. The second side plate 6 and the other open end of the U-shaped connecting plate 231 and the impact cylinder 31 are both detachably connected, preferably by bolts, to achieve a fixed connection between the vertical moving mechanism 2 and the vibration impact mechanism 3, that is, the lifting cylinder 21 drives the impact cylinder 31 to move along the first square tube bracket 12. The first side plate 5 and the second side plate 6 are both L-shaped structures, which are convenient for achieving the connection between the vertical moving mechanism 2 and the vibration impact mechanism 3, and are adapted to the shape of the connecting piece 23 and the impact cylinder 31. In actual application, they play a role in connecting and protecting the impact cylinder 31 and the connecting piece 23 to avoid damage to the components.
[0043] Optionally, the first fastener 24 and the second fastener 25 are sleeved on the outer surface of the lifting cylinder 21, and the first fastener 24 and the second fastener 25 both include two ribs that are detachably connected to facilitate disassembly and installation.
[0044] When the vibration pile driving device is used in an excavator for piling operations, the vibration pile driving device is installed on the working arm at the end of the excavator through the connecting mechanism 4, and the working arms of the excavator are adjusted so that the impact head 32 is perpendicular to the pile head for vibration piling. At this time, the vertical moving mechanism 2 and the vibration impact mechanism 3 are both located at a higher position in the vertical direction of the mounting frame 1. As the piling process proceeds, the penetration depth of the pile head increases, and the vibration impact mechanism 3 is driven by the vertical moving mechanism 2 to move vertically downward along the mounting frame 1, thereby ensuring that the piling operation is carried out vertically downward. When the vibration impact mechanism 3 is close to the lower end of the mounting frame 1, the vibration impact mechanism 3 is moved to the upper end of the mounting frame 1 again, and then the working arm of the excavator is adjusted to move downward separately, so that the vibration impact mechanism 3 is moved vertically downward along the mounting frame 1. The impact mechanism 3 rests against the pile to be impacted again, and the above process is repeated until the pile driving operation is completed, thereby greatly reducing the frequency of adjusting the excavator working arm and lowering the requirements for working accuracy; and when the vertical sliding assembly 22 needs to be replaced, first remove the first side plate 5 and the second side plate 6 to achieve the separation of the vertical moving mechanism 2 and the vibration impact mechanism 3, and then disassemble the connecting member 23 from the vertical sliding assembly 22. Specifically, the U-shaped connecting plate 231 and the cover plate 232 are separated by removing the connecting bolts, and the U-shaped connecting plate 231 and the cover plate 232 can be removed from the mounting frame 1, and the first slide plate 221, the second slide plate 222, the third slide plate 223 and the fourth slide plate 224 can be further disassembled and replaced.
[0045] The vibrating pile driving device provided by the utility model has a structural design 2 of the vertical moving mechanism that is easy to disassemble and install. When the vertical sliding assembly 22 is worn and needs to be replaced, it is convenient for the staff to quickly disassemble and replace it. At the same time, by providing a boss 26 and a first fastener 24 and a second fastener 25 at both ends on the lifting cylinder 21, the lifting cylinder 21 can drive the connecting piece 23 and the vertical sliding assembly 22 to move up and down along the mounting frame 1 and the synchronous movement of the vibrating impact mechanism 3.
[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
