Description

Technical Field

[0001] This utility model relates to the technical field of drilling and pile driving integrated machine, specifically a static pressure pile driving device for drilling and pile driving integrated machine. Background Technology

[0002] The process of drilling, mixing cement soil or jet grouting cement, and then implanting precast pipe piles is currently widely used. The integrated drilling and pile planting machine is used in this process. A tower that rotates concentrically is fixed on a turntable driven by a motor and gears. One or more power heads and drill rods, a welding extension device for welding and extending multiple precast pipe piles, etc. can be installed on the tower along the circumference. Generally, a static pressure pile driving device is also installed on the construction platform or base of the integrated machine. The use of the static pressure pile driving device for pile planting has the advantages of low vibration and low noise.

[0003] In actual construction, there is a need for static pressure piling of conventional piles in the middle of the construction platform, as well as static pressure piling of side piles in narrow spaces, and in some cases, static pressure piling of corner piles in narrow spaces.

[0004] In existing technologies, two structures are generally adopted to meet the above requirements for static pressure pile driving. One type involves fixing a central static pressure pile driving device, a side pile static pressure pile driving device, and a corner pile static pressure pile driving device separately on an integrated machine. The other type uses only one static pressure pile driving device. For planting conventional piles (central piles), a plunger is inserted into the insertion hole and then fixed to the middle of the construction platform with threaded fasteners. For planting side piles, the device is disassembled from the middle of the construction platform, and then a plunger is inserted into the insertion hole and fixed to the edge of the construction platform with threaded fasteners. For planting corner piles, the device is disassembled from the edge of the construction platform, and then a plunger is inserted into the insertion hole and fixed to the corner of the construction platform with threaded fasteners.

[0005] The first structure mentioned above significantly increases the equipment cost, floor space, and difficulty in moving the all-in-one machine, and the increased floor space can sometimes hinder construction in confined spaces.

[0006] The second type of structure requires the use of a crane for disassembly and reinstallation of the static pressure pile driving device during the replacement of conventional pile, edge pile, or corner pile positions. This process is relatively troublesome, slow, and labor-intensive, which increases the difficulty of construction and reduces the efficiency of construction. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a static pressure pile driving device for a drilling and pile driving integrated machine that is relatively cost-effective and convenient, quick and labor-saving to disassemble and install when changing the pile driving position.

[0008] The technical solution of this utility model is to provide a static pressure pile driving device for a drilling and pile driving integrated machine, including a static pressure pile driving device body connected to the tower or turntable of the drilling and pile driving integrated machine. The static pressure pile driving device body has at least one set of pin assemblies with pins driven by a linear drive device. The construction platform has multiple sockets with pin holes for engaging with the pins in the pin assemblies to position the static pressure pile driving device body at different pile driving positions.

[0009] With the above structure, the static pressure pile driving device of this utility model for drilling and pile driving integrated machine has the following advantages:

[0010] Compared to the first structure of the existing technology, only one static pressure pile driving device body is needed, which saves on equipment costs, does not increase the footprint, and does not increase the difficulty of moving the integrated machine or hinder construction in narrow spaces.

[0011] Compared to the second structure of the existing technology, this method eliminates the need for a crane during the replacement of conventional pile planting, edge pile planting, or corner pile planting positions. Furthermore, each replacement does not require disassembly and reinstallation of the static pressure pile driving device. Disassembly simply requires using a linear drive device to disengage the pin from the socket's pin hole. After the tower rotates the static pressure device to the new pile planting position, a linear drive device is used to reinsert the pin into the socket's pin hole. This operation is extremely convenient, quick, and labor-saving, significantly reducing construction difficulty and greatly improving construction efficiency.

[0012] Furthermore, the static pressure pile driver body is fixed to the outer circumference of the lower end of the tower via four hinge points (top, bottom, front, and back). With this structure, the connection between the static pressure pile driver body and the tower is firm, stable, and reliable.

[0013] Furthermore, the pin in the aforementioned pin assembly is driven by an electric push rod, a pneumatic cylinder, or a hydraulic cylinder. This structure makes inserting and removing the pin more convenient, faster, and less strenuous.

[0014] Furthermore, the housing of the electric push rod, cylinder, or hydraulic cylinder also serves as a pin. The end of the drive rod of the electric push rod, cylinder, or hydraulic cylinder away from the housing is hinged to the body of the static pressure pile driving device. A first support base is fixed on the body of the static pressure pile driving device. The first support base has a first hole for accommodating the retracted pin or for the pin to slide into the pin hole of the socket to position the body of the static pressure pile driving device. With the above structure, the pin assembly is simpler and easier to operate. The extension and retraction of the drive rod of the electric push rod, cylinder, or hydraulic cylinder, which drives the housing (which also serves as a pin) to extend and insert into the pin hole of the socket, or to retract and accommodate in the first hole of the first support base, is more flexible, faster, more stable, and more reliable.

[0015] Furthermore, a second support is fixed to the main body of the static pressure pile driving device. The second support has a second hole for accommodating the free end of the pin that passes through the pin hole of the socket. The axes of the first hole of the first support, the pin hole of the socket, and the second hole of the second support, arranged from left to right, are on the same straight line. With the above structure, when the main body of the static pressure pile driving device is located at the pile planting position and during the pile planting process, since the housing of the linear drive device, which also serves as the pin, is simultaneously inserted into the first hole of the first support, the hole of the socket, and the second hole of the second support, the connection between the main body of the static pressure device and the construction platform is firm, reliable, and has good mechanical properties.

[0016] Furthermore, the pin is a rectangular pin, and the first hole, pin hole, and second hole are all rectangular holes whose shape and size match the rectangular pin. With the above structure, the pin and pin hole have no room for circumferential rotation, resulting in better guiding performance, smooth sliding, and reliability.

[0017] Furthermore, the pin assembly consists of two sets, which are symmetrically fixed to the front and rear sides of the bottom of the static pressure pile driving device body. With this structure, during the pile driving process, the connection between the static pressure device body and the construction platform is more robust, reliable, and exhibits better mechanical performance when the static pressure pile driving device body is positioned at the pile driving location.

[0018] Furthermore, two first sockets with first pin holes are fixed to the top of the construction platform inside the tower. Each first pin hole is a pin hole that mates with a pin to position the static pressure pile driving device body in the conventional pile driving position. With the above structure, the operation of switching the static pressure device body to the conventional pile driving position is more convenient, faster, and less labor-intensive. Moreover, when driving conventional piles, the connection between the static pressure device body and the construction platform is more secure, more reliable, and has better mechanical performance.

[0019] Furthermore, two second sockets with second pin holes are fixed to the top of the construction platform on the outer side of the tower. Each second pin hole is a pin hole that mates with a pin to position the static pressure pile driving device body at the side pile planting position. With the above structure, the operation of switching the static pressure device body to the side pile planting position is more convenient, faster, and less labor-intensive. Moreover, when planting side piles, the connection between the static pressure device body and the construction platform is more secure, more reliable, and has better mechanical performance.

[0020] Furthermore, two third sockets with third pin holes are fixed to the top of the construction platform at the outer corner of the tower. Each third pin hole is a pin hole that mates with a pin to position the static pressure pile driver body at the corner pile planting position. With the above structure, the operation of switching the static pressure device body to the corner pile planting position is more convenient, faster, and less labor-intensive. Moreover, when planting corner piles, the connection between the static pressure device body and the construction platform is more secure, reliable, and has better mechanical performance.

[0034] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions of specific embodiments are intended to aid in understanding this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various specific embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown.

[0036] The existing drilling and pile-planting integrated machine 1 includes a construction platform 11, a turntable 12 rotatably fitted at one end of the construction platform 11, a tower 13 concentric with and fixed on the turntable 12, and a crane 14 fixed at the other end of the construction platform 11. The crane 14 in the figure does not show wire ropes or hooks. The construction platform 11 is also called the chassis. The general structure of the turntable 12 is as follows: an outer gear ring is fixed to the top surface of the construction platform, and an inner ring, or slewing support ring, is fixed to the bottom surface of the turntable. The inner ring rotatably fits within the outer gear ring. A rotary motor or electric motor is fixed to the top surface of the turntable. The shaft of the rotary motor or electric motor passes through a hole on the turntable and rotatably fits with the hole. A gear is fixed to the free end of the shaft, and the gear meshes with the outer gear ring on the chassis. The rotary motor or electric motor drives the gear to rotate, causing the turntable to revolve around the outer gear ring, thereby causing the turntable and the tower fixed on it to rotate around their own axis. The general structure of the existing static pressure pile driving device body 2 is as follows: it includes two symmetrically arranged gantry pile driving frames, each gantry pile driving frame is equipped with a pile gripper or pile gripping box or pile clamping box driven by a pile driving cylinder, and the pile gripper is symmetrically equipped with multiple, such as two or four, transverse pile gripping cylinders.

[0037] This utility model provides an embodiment of a static pressure pile driving device for a drilling and pile driving integrated machine, which includes a static pressure pile driving device body 2 connected to a tower 13 or turntable of the drilling and pile driving integrated machine 1. The static pressure pile driving device body 2 has at least one set of pin assemblies 3 driven by a linear drive device to drive pins 31. The construction platform 11 has multiple sockets 4 with pin holes 41 for engaging with the pins 31 in the pin assemblies 3 to position the static pressure pile driving device body 2 at different pile driving positions.

[0038] The pin 31 is preferably a rectangular pin 31. The pin hole 41 mentioned above, the first hole 331 and the second hole 341 mentioned below are all rectangular holes 41 whose shape and size match the rectangular pin 31. That is, the pin hole 41 is a rectangular pin hole 41, the first hole 331 is a rectangular first hole 331, and the second hole 341 is a rectangular second hole 341.

[0039] The pin 31 in the pin assembly 3 is preferably driven by an electric push rod, a pneumatic cylinder, or a hydraulic cylinder in a linear drive device.

[0040] Preferably, the housing of the electric push rod, cylinder, or hydraulic cylinder also serves as a pin 31, such as a rectangular pin 31. The end of the drive rod 32 of the electric push rod, cylinder, or hydraulic cylinder away from the housing 35 is hinged to the static pressure pile driving device body 2. A first support base 33 is fixed or welded to the static pressure pile driving device body 2. The first support base 33 has a rectangular first hole 331 for accommodating the pin 31 when retracted, or for the pin 31 to slide into the rectangular pin hole 41 of the socket 4 to position the static pressure pile driving device body 2. The drive rod 32 is like the push rod in an electric push rod, or the piston rod in a cylinder or hydraulic cylinder. The housing that also serves as a pin 31 is like the housing in an electric push rod 34, or the cylinder body in a cylinder or hydraulic cylinder. The housing of the electric push rod that also serves as a rectangular pin 31, or the cylinder body of the cylinder or hydraulic cylinder, can all be chamfered rectangles.

[0041] The static pressure pile driving device body 2 is also fixedly welded with a second support base 34. The second support base 34 has a rectangular second hole 341 that accommodates the free end of the rectangular pin 31, which passes through the rectangular pin hole 41 of the socket 4. The axes of the rectangular first hole 331 of the first support base 33, the rectangular pin hole 41 of the socket 4, and the rectangular second hole 341 of the second support base 34 are on the same straight line.

[0042] Preferably, there are two sets of pin assemblies 3, which are symmetrically fixed on the front and rear sides of the bottom of the static pressure pile driving device body 2.

[0043] The top of the construction platform 11 inside the tower 13 is fixed with two first sockets 42 with rectangular first pin holes 421 welded on them. Each rectangular first pin hole 421 is a pin hole that cooperates with each rectangular pin 31 to position the static pressure pile driving device body 2 on the conventional pile driving position.

[0044] The top of the construction platform 11 on the outer side of the tower 13 is fixed with two second sockets 43 with rectangular second pin holes 431 welded on them. Each rectangular second pin hole 431 is a pin hole that cooperates with each rectangular pin 31 to position the static pressure pile driving device body 2 on the side pile planting position.

[0045] See Figure 1 , Figure 2 and Figure 5The top of the construction platform at the outer corner of the tower is fixed with two third sockets, each with a rectangular third pin hole, welded to it. Each rectangular third pin hole mates with a pin to position the static pressure pile driver body at the corner pile planting position. Specifically, the structure can be such that the top of the construction platform at the outer front corner of the tower has two third sockets with third pin holes welded to it; or the top of the construction platform at the outer rear corner of the tower has two third sockets with third pin holes welded to it; or the top of the construction platform at the outer front corner of the tower has two third sockets with third pin holes welded to it, and the top of the construction platform at the outer rear corner of the tower has two third sockets with third pin holes welded to it simultaneously. The structural diagrams described in this section are not shown.

[0046] like Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, the static pressure pile driving device body 2 is fixed to the outer circumference of the lower end of the tower 13 via four hinge points (top, bottom, front, and back); the ends of the two drive rods 32 away from the shell (i.e., the pins 31) are hinged to the static pressure pile driving device body 2. It is easy to understand that the four hinge points are one of the inventive features of this utility model, and the hinges of the ends of the two drive rods 32 away from the shell (i.e., the pins 31) to the static pressure pile driving device body 2 are also one of the inventive features of this utility model. However, the specific hinge structure of each hinge point is a conventional structure. For example, each hinge point could be: two ear plates (e.g., two first ear plates 51) fixed or welded to the outer circumference of the lower end of the tower 13; a connecting plate (e.g., a first connecting plate 21) fixed or welded to the static pressure pile driving device body 2; two ear plates (e.g., two second ear plates 22) fixed or welded to the bottom surface of the static pressure pile driving device body 2; and a connecting plate (e.g., a second connecting plate 321) integrally formed at the end of the drive rod 32 away from the shell (i.e., the pin 31). After the connecting plate is inserted between the two ear plates, such as when the first connecting plate 21 is inserted into the two first ear plates 15 and the second connecting plate 321 is inserted into the two second ear plates 22, the pin holes on the connecting plate and the respective pin holes on the two ear plates are coaxial. A pin is inserted into the three pin holes on the coaxial axis. For example, the second pin hole 211 on the first connecting plate 21 and the respective first pin holes 151 on the two first ear plates 15 are coaxial, and a pin is inserted into the three pin holes on the coaxial axis. Similarly, the pin holes on the second connecting plate 321 and the respective pin holes 221 on the two second ear plates 22 are coaxial, and a pin is inserted into the three pin holes on the coaxial axis and axially limited. If one end of the pin has a shoulder or a large head for axial limitation, the other end of the pin may have a threaded hole. A bolt with a shoulder or a large head is tightened into the threaded hole for axial limitation. The second connecting plate 321 can also be called the second connecting block. The pin can also be called a hinge pin.

[0047] It is easy to understand that the static pressure pile driving device can also be connected to the turntable of the drilling and pile driving machine. For example, a support frame can be fixed on the turntable on one side of the tower. The support frame is fixedly connected to the static pressure pile driving device and can also be fixedly connected to the tower at the same time.

In case of any inconsistency between the drawings and the text description, or between the drawings themselves, the text description shall prevail.

[0049] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
