Description

Technical Field

[0001] The present invention relates to a micro pile driver, in particular to an electric power split crawler type micro pile driver. Background Art

[0002] Pile drivers, essential equipment for foundation construction, are particularly useful for transmission line foundations. Driven by the "Six Precisions and Four Standards" requirements for power grid construction, transmission line foundation construction has shifted from traditional manual labor to mechanized operations, with fully mechanized construction practically achieved in plain areas. However, mechanized foundation construction in mountainous areas is still in its exploratory stages, with existing pile drivers presenting a major challenge.

[0003] Current pile drivers, such as rotary drilling rigs, are primarily designed for flatland or highway construction. They are large and generally weigh over 30 tons. While these pile drivers excel in foundation pit construction in plain areas, they have poor maneuverability in undulating terrain, making them difficult to transport to mountainous areas and unsuitable for operations there.

[0004] This issue not only limits the use of pile drivers in mountainous areas but also raises a series of challenges. First, large pile drivers may require felling trees and widening roads to access the construction site, which may encounter obstacles in environmental review. Second, mountainous pole towers are often located on hillsides, and the stability of existing machinery may not meet construction requirements. Third, mountainous foundations primarily use excavation or rock anchor foundation methods. Manual excavation carries the risk of collapse and efficiency issues, and existing pile drivers are unable to meet the construction needs under these special conditions.

[0005] Therefore, the size and weight limitations of existing pile drivers have become a major obstacle to the mechanization of foundation construction in mountainous areas and other challenging environments. Addressing this issue will not only improve construction efficiency, reduce material loss and environmental pollution, but also significantly reduce the risk of manual construction, further promoting the shift from labor-intensive to equipment-intensive construction. This shift is crucial for achieving first-class construction technology, equipment, and project management.

[0006] Furthermore, existing pile drivers primarily utilize a drill rod and drill bit to drill a hole and then drive the pile. Because they utilize micro-pile drivers, the drill rods must be assembled one by one. After each drill rod is driven, the rotating head must be separated from the drill rod. A new drill rod is then connected to the existing drill rod, and the other end of the new drill rod is connected to the rotating head. This process is repeated to achieve the desired drilling depth.

[0007] The assembly and removal of drill pipes requires two people to perform manually. One person must support the drill pipe to be installed, while the other uses a tool to rotate the drill pipe and complete the threaded connection with the bottom drill pipe. Due to the heavy weight of the drill pipe, this installation method is both laborious and time-consuming, placing a heavy physical strain on the workers. Manual operation can also lead to inaccurate assembly, affecting construction quality and efficiency.

[0008] In addition, there are more than one drill rods, which need to be carried separately. During transportation, the drill rods may collide with each other, resulting in damage to the drill rods. The damaged drill rods will not be able to be used normally, which may cause construction delays and increased costs. In addition, the process of transporting the drill rods to the installation site for installation is very inconvenient, time-consuming and labor-intensive, and can easily cause personal injury.

[0009] The traditional process of carrying, transporting, installing and moving drill pipes involves many tedious manual operations. These operations not only require high skills from personnel, but are also prone to errors, thus affecting the overall construction progress and quality.

[0010] Therefore, there are many problems in the installation, carrying and transportation of existing pile driver drill rods, which not only increases the consumption of manpower and material resources, but also limits the construction efficiency and quality. Summary of the Invention

[0011] In order to solve the above problems, the present invention provides an electric-disassembled crawler-type micro pile driver, which adopts a modular design. The pile driver can be carried and transported separately by utilizing the disassembled structure of the pile driver, so that the pile driver can easily enter undulating terrain and more conveniently enter mountainous areas for operation. At the same time, the drill rod can be carried and installed. The installation and transportation of the drill rod only requires pushing and pulling the conveying plate. In addition, the threaded installation of the drill rod to be installed can be completed by utilizing the resetting process of the pull-out conveying plate. No manual support is required, and no manual tools are required for threaded installation. Manual intervention is reduced, and manpower and material resources are reduced, which can effectively solve the shortcomings of the existing technology.

[0012] The present invention is realized by the following technical solution: an electric split crawler micro pile driver, comprising:

[0013] A walking device, the walking device is composed of at least two walking mechanisms, and walking track assemblies are provided on both sides of the walking mechanism;

[0014] Connecting plates, the connecting plates being at least two in number. When at least two running mechanisms are arranged side by side, the at least two connecting plates are inserted into the assembly grooves preset in the running mechanisms from one side of the running mechanisms in an upper and lower distribution manner, thereby connecting the at least two running mechanisms together through the at least two connecting plates.

[0015] A groove is provided on the same side of at least two walking mechanisms. When the walking mechanisms are connected together, an operating cavity is formed by the two joined grooves.

The top portions of the drill rods pass through the pull-out conveying plate and are located in a receiving cavity formed by the pull-out conveying plate and the lower end surface of the connecting plate. The bottom portions of the drill rods are supported in a supporting cavity formed on a connecting plate located at the bottom. The pull-out conveying plate is controlled by a pull-out driving mechanism to perform a reciprocating conveying motion relative to one side of the punching mechanism to convey the drill rods to the punching mechanism.

[0018] A movable supporting mechanism, wherein both sides of the movable supporting mechanism are slidably mounted in slide grooves provided on both sides of the operating chamber, and a linkage mechanism is provided between the movable supporting mechanism and the pull-out conveying plate. When the pull-out conveying plate moves toward the punching mechanism, the movable supporting mechanism moves toward the punching mechanism and is displaced to be directly below the punching mechanism. The drill rod on the side closest to the punching mechanism is buckled into the movable supporting mechanism for support by using the pull-out conveying plate.

[0019] When the pull-out conveyor plate retracts and resets, the movable supporting mechanism moves toward the side away from the punching mechanism through the linkage mechanism, and the drill rod to be installed is driven to rotate by the reset pull-out conveyor plate. At this time, the drill rod to be installed is automatically threaded with the drill rod at the bottom.

[0020] As a preferred technical solution, the top of each drill rod is provided with a threaded connector, the top of each threaded connector is provided with a driving rod protruding therefrom, the outer wall surface of the driving rod is provided with driving teeth surrounding the driving rod, the bottom of the drill rod is provided with a threaded connection hole corresponding to the threaded connector, and the bottom of the threaded connection hole is provided with a retreat hole corresponding to the driving rod;

[0021] A driving groove is provided on the lower end surface of the pulling and conveying plate, and a rack is provided on one side of the driving groove. When the drill rod to be installed is transported to the bottom position of the punching mechanism, the bottom of the drill rod to be installed loses the support of the support cavity, and slides down relative to the pulling and conveying plate by its own weight, and docks with the drill rod at the bottom. At this time, the drill rod to be installed is separated from the pulling and conveying plate, and the driving rod is just located in the driving groove of the pulling and conveying plate.

The drill rod to be installed is buckled into the supporting clamping ring by using the pull-out conveying plate. The supporting clamping ring is made of elastic metal parts, and its clamping force on the drill rod is less than the gravity of the drill rod.

[0024] A guide slot is provided on each movable plate on both sides of the installation port, and a guide plug is provided on each side of the supporting clamp at a position corresponding to the guide slot, and the guide plug is respectively inserted into the guide slots on both sides.

When the ejection spring is fully ejected, the movable plate is located directly below the punching mechanism.

[0026] The telescopic drive rod is arranged on the other side of the movable plate, and the telescopic drive rod is connected to the air storage bag through the air guide tube. When the air storage bag is squeezed by the pulling and conveying plate, the telescopic drive rod is filled with gas from the air storage bag and ejected. At this time, the ejected telescopic drive rod pushes the movable plate to move in the direction of the ejection spring. At this time, the ejection spring is compressed, the movable plate is misaligned with the punching mechanism, and the movable plate is located at the farthest end of the pulling and conveying plate.

[0027] The air storage bag is installed in a connecting plate at the top, and the air storage bag is located at the farthest end from the punching mechanism. The two sides of the pulling and conveying plate are respectively slidably assembled in the pulling grooves opened on both sides of the bottom of the connecting plate, and the air storage bag is installed in the pulling grooves.

[0028] As a preferred technical solution, the drawer conveyor plate is provided with a step surface on each side of the air storage bag. One end of the air storage bag is fixed to the drawer groove, and the other end is in contact with and supported by the step surface on the drawer conveyor plate. When the drawer conveyor plate is reset, the air storage bag is squeezed by the drawer conveyor plate, and the air guide tube is arranged in the wiring channel inside the walking mechanism.

[0029] The telescopic drive rod includes a telescopic tube and a telescopic rod. A sealed air storage chamber is provided in the telescopic tube. A sealing piston is installed at one end of the telescopic rod and is sealed into the air storage chamber. The air storage chamber is connected to the air storage bag through an air guide tube.

[0030] As a preferred technical solution, at least two connecting plates include a first connecting plate and a second connecting plate, the first connecting plate is located at the upper end of the second connecting plate, and the pulling conveying plate is pulled and installed at the bottom position of the first connecting plate, the pulling drive mechanism is installed on the first connecting plate, and the support cavity is formed on the second connecting plate.

[0031] As a preferred technical solution, the pulling and drawing drive mechanism includes a large-stroke driving cylinder, which is fixedly mounted on the upper end of the first connecting plate, and a cylinder rod of the driving cylinder. The first connecting plate has a driving slot penetrating the stroke path of the cylinder rod, and a driving block is fixedly mounted on the cylinder rod. The driving block passes through the driving slot and is connected to the pulling and drawing conveying plate at the bottom, and the pulling and drawing conveying plate is driven by the large-stroke driving cylinder to perform reciprocating pulling and drawing movements.

[0032] As a preferred technical solution, an assembly block is provided on both sides of the connecting plate at positions facing the assembly groove, and the cross-sections of the assembly block and the assembly groove are both T-shaped.

[0033] As a preferred technical solution, the punching mechanism includes a control host, a lifting mechanism, a rotary drive mechanism and a turntable.

[0034] The rotary drive mechanism includes a mounting plate, on which a reducer and a rotary drive motor are mounted, the input end of the reducer is connected to the output shaft of the rotary drive motor, and the output end of the reducer is connected to the connecting shaft. The reducer and the rotary drive motor are both arranged on the mounting plate, and the mounting plate is mounted on the lifting mechanism and driven to rise or fall by the lifting mechanism. The rotary drive mechanism and the lifting mechanism are both controlled by the control host.

[0035] The beneficial effects of the present invention are as follows: 1. The present invention innovatively divides the pile driver into two independent modules, namely the first traveling mechanism and the second traveling mechanism. This split structure not only facilitates the transportation of the pile driver, but also reduces the environmental impact in specific areas such as mountainous areas, and reduces damage to trees and the surrounding natural environment;

[0036] By transporting them separately and independently, the pile driver can flexibly enter complex terrains such as mountainous areas. After entering the target area, the two modules can be quickly assembled to achieve precise construction at specific locations. At the same time, with the help of the crawler structure, the pile driver has better terrain adaptability and can move flexibly in complex environments such as mountains.

[0037] In addition, the power of the entire traveling mechanism and the power of drilling are driven by electric motors. This structure not only enhances the environmental protection characteristics of the pile driver, but also promotes the miniaturization of the pile driver of the present invention, that is, a micro pile driver, making it more suitable for use in special occasions.

[0038] Second, the pile driver of the present invention is equipped with a pull-out conveyor plate driven by a pull-out drive mechanism at the connection position between the first traveling mechanism and the second traveling mechanism. The drill rods can be all installed on this conveyor plate in advance to prepare for later installation, thereby reducing the situation where the drill rods collide with each other during transportation and cause damage to the drill rods. When installing the drill rods, it is only necessary to control the conveyor plate by the pull-out drive mechanism to smoothly convey the drill rods to be installed in the direction of the drilling mechanism, thereby avoiding the tedious manual handling process.

[0039] When the conveyor plate delivers the drill rod to the appropriate position of the drilling mechanism, the drill rod to be installed can be easily loaded into the movable supporting mechanism. The movable supporting mechanism keeps the drill rod stable, and the reset force of the conveyor plate can be used to achieve precise rotation of the drill rod. As the conveyor plate retracts, the drill rod to be installed is threadedly connected with the installed drill rod. The entire process does not require manual intervention or the use of tools.

[0040] The present invention utilizes the retraction force of the pull-out conveyor plate to achieve threaded engagement of the two drill rods, making the structure more reasonable, reducing manual work, and greatly improving the installation effect and efficiency. This not only simplifies the operation process, but also reduces the risk and intensity of manual work, providing an efficient and user-friendly solution for modern, mechanized pile foundation construction.

[0041] 3. The movable supporting mechanism of the present invention does not interfere with the drilling mechanism when the drilling mechanism rotates to drill holes. When a new drill rod needs to be installed, it can be accurately moved to the bottom position of the drilling mechanism through the linkage mechanism. This design enables the movable supporting mechanism to work in conjunction with the pull-out conveyor plate to achieve smooth and rapid installation of the drill rod. This structure not only improves the convenience and efficiency of operation, but also ensures the accuracy and safety of the entire process. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.

[0058] Any feature disclosed in this specification (including any appended claims, abstract, and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. In other words, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0059] like Figure 1-Figure 3 As shown, an electric split crawler micro pile driver of the present invention includes a walking device, wherein the walking device is composed of at least two walking mechanisms spliced ​​together, and walking crawler 19 components are provided on both sides of the walking mechanism, and the crawler 19 components include crawler 19, driving wheel 3, support wheel and crawler 19 driving motor, and the crawler 19 driving motor is installed in the walking mechanism, and crawler 19 is covered and installed on the outside of each driving wheel 3 and support wheel. The crawler 19 structure is relatively common and will not be described in detail here. In this embodiment, at least two walking mechanisms include a first walking mechanism 1 and a second walking mechanism 2. When not in use during transportation, the two walking mechanisms are carried and carried separately. After being transported to a designated location, the two walking mechanisms are spliced ​​and assembled to form the entire walking device. Working modules such as a punching mechanism and a cooling mechanism can be installed on the top of the walking device. Therefore, in this embodiment, the entire walking device is disassembled to achieve independent carrying, and the assembly method is used to reduce damage to the environment, and the crawler 19 structure is used to enable it to walk in a more complex environment for operation;

[0060] The two traveling mechanisms are further provided with connecting plates. The connecting plates are in two pieces. When the two traveling mechanisms are arranged side by side, the two connecting plates are inserted into the assembly grooves 50 preset in the traveling mechanisms from one side of the traveling mechanisms in an upper and lower distribution manner. The two traveling mechanisms are connected together through the two connecting plates. When the two traveling mechanisms are arranged, the connecting plates can be inserted into the upper and lower ends respectively. The two traveling mechanisms can be connected together by using the connecting plates, which is very convenient to install.

[0061] In order to achieve drilling operations, a groove is provided on the same side of each of the two traveling mechanisms in this embodiment. When the traveling mechanisms are connected together, an operating chamber 14 is formed by the two joined grooves. In order to complete the drilling operation, this embodiment also includes a punching mechanism. The punching mechanism is mounted on the upper end of any traveling mechanism, and the rotating drive end of the punching mechanism is located on the upper end surface of the operating chamber 14. The bottom of the punching mechanism corresponds to the operating chamber. The punching mechanism is connected to the drill rod 100, so the drilling operation is carried out in this operating chamber 14.

[0062] like Figure 2 、 Figure 5 and Figure 6 As shown, a pull-out conveying plate 18 is movably provided on the lower end surface of a connecting plate at the top, and a plurality of movably arranged drill rods 100 are installed side by side on the pull-out conveying plate 18. The top portion of the drill rod 100 passes through the pull-out conveying plate 18 and is located in the accommodating cavity formed by the pull-out conveying plate 18 and the lower end surface of the connecting plate. The bottom of the drill rod 100 is supported in a supporting cavity 24 formed on a connecting plate at the bottom. The pull-out conveying plate 18 is controlled by a pull-out driving mechanism to perform a reciprocating conveying action relative to one side of the punching mechanism to convey the drill rod 100 to the punching mechanism. The bottom of the drill rod 100 is horizontal and can be moved by the bottom The support cavity 24 provides support so that when the drill rods 100 are installed on the pull-out conveying plate 18, if the pull-out conveying plate 18 is in the initial state, the bottom of the drill rods 100 are supported by the support cavity 24 and will not slide down. However, once the drill rods 100 leave the position of the support cavity 24 along with the pull-out conveying plate 18, the bottom of the drill rods 100 loses the support of the support cavity 24 and the drill rods 100 will slide down under the action of their own gravity. Therefore, when the pull-out conveying plate 18 carries the drill rods 100 to the punching mechanism position, the drill rods 100 located at the punching mechanism position will lose the support of the support cavity 24 and slide down.

[0063] In this embodiment, before the operation, that is, during the transportation process, the drill rods 100 can be installed separately on the pulling and conveying plate 18, and the drill rods 100 are conveyed along with the pulling and conveying plate 18, so that there is no chance for the drill rods 100 to collide with each other, and there will be no problem of damage to the drill rods 100 caused by collision due to centralized transportation of the drill rods 100, and no collision damage to the threads on the drill rods 100 will be caused, so that the service life of the drill rods 100 is extended, and the storage of the drill rods 100 is also neater. When the drill rods 100 need to be installed one by one, only the pulling and conveying plate 18 can be driven back and forth in unison to realize the transportation and installation of the drill rods 100 one by one. The whole process does not require manual handling of the drill rods 100, and the operation is very labor-saving, more neat and orderly.

[0064] In order to allow the drill rod 100 to be installed to accurately position the drill rod 100 at the bottom and complete the threaded connection of the two drill rods 100, so that the drill rod 100 to be installed will not fall over, eliminating the need for manual support, this embodiment also includes a movable support mechanism, the two sides of the movable support mechanism are slidably installed in the slide grooves 31 opened on both sides of the operating chamber 14, and a linkage mechanism is set between the movable support mechanism and the pull-out conveying plate 18. When the pull-out conveying plate 18 moves toward the punching mechanism, the movable support mechanism moves toward the punching mechanism and is displaced to the bottom of the punching mechanism, and the pull-out conveying plate 18 is used to buckle the drill rod 100 closest to the punching mechanism into the movable support mechanism for support. Figure 5 and Figure 6 As shown, the movable supporting mechanism moves along with the movement of the pulling and conveying plate 18, that is, when the pulling and conveying plate 18 is reset, the movable supporting mechanism moves away from the punching mechanism and does not interfere with the drilling action of the drill rod 100 driven by the punching mechanism. Correspondingly, when the pulling and conveying plate 18 moves toward the punching mechanism, that is, when the punching mechanism conveys a new drill rod 100, since the pulling and conveying plate 18 and the movable supporting mechanism are provided with a linkage mechanism, when the pulling and conveying plate 18 moves, the movable supporting mechanism can be disassembled and assembled with the punching mechanism and moved, so that the movable supporting mechanism moves to the bottom of the punching mechanism. In this way, when the pulling and conveying plate 18 is transported with the drill rod 100, the drill rod 100 to be installed can be buckled into the movable supporting mechanism, and the movable supporting mechanism can be used to The supporting mechanism supports and supports the drill rod 100 to keep it vertical; when the drill rod 100 is buckled into the movable supporting mechanism for support, since the bottom of the drill rod 100 at the corresponding position loses the support of the supporting cavity 24, the drill rod 100 will slide down relative to the movable supporting mechanism and slide down relative to the drill rod 100 mounting hole of the pull-out conveying plate 18, so that the top of the drill rod 100 is displaced to the lower end surface of the pull-out conveying plate 18, so that the drill rod 100 no longer limits the resetting of the pull-out conveying plate 18. When the drill rod 100 to be installed is located in the movable supporting mechanism and slides down, the pull-out conveying plate can be retracted. The drill rod 100 that has fallen down will no longer limit the pull-out conveying plate 18, and the pull-out conveying plate 18 can be reset.

[0065] When the pull-out conveying plate 18 is retracted and reset, the movable supporting mechanism moves toward the side away from the punching mechanism through the linkage mechanism, and the drill rod 100 to be installed is driven to rotate by the reset pull-out conveying plate 18. At this time, the drill rod 100 to be installed is automatically threadedly connected with the drill rod 100 at the bottom, and a driving groove 32 is provided on the lower end surface of the pull-out conveying plate 18. A rack 33 is provided on one side of the driving groove 32. When the drill rod 100 to be installed is transported to the bottom position of the punching mechanism, the bottom of the drill rod 100 to be installed loses the support of the support cavity 24 and slides down relative to the pull-out conveying plate 18 by its own weight and connects with the drill rod 100 at the bottom. At this time, the drill rod 100 to be installed is separated from the pull-out conveying plate 18, and the driving rod 101 is just located in the driving groove 32 of the pull-out conveying plate 18, and the reset force of the pull-out conveying plate 18 drives the drill rod 100 to be installed to rotate relative to the drill rod 100 at the bottom, completing the threaded assembly between the drill rods 100;

[0066] Specifically, such as Figure 6-Figure 8As shown, the top of the drill rod 100 is provided with a threaded connector 102, and a driving rod 101 is protruded from the top of the threaded connector 102. The outer wall surface of the driving rod 101 is provided with driving teeth around the driving rod 101. The bottom of the drill rod 100 is provided with a threaded connection hole 36 corresponding to the threaded connector 102, and a retreat hole 35 is provided at the bottom of the threaded connection hole 36 corresponding to the driving rod 101. When the working drill rod 100 drills a hole in the soil, the drill rod 100 is separated at this time, and a new drill rod 100 is transported over by using the pulling conveying plate 18. The drilling mechanism rises, and when the pulling conveying plate 18 pulls the drill rod to be installed When the rod 100 is transported, the movable supporting mechanism moves to the bottom of the punching mechanism, and the pull-out conveying plate 18 is used to buckle the drill rod 100 to be installed into the movable supporting mechanism for support. At this time, the bottom of the drill rod 100 loses the support of the support cavity 24 and slides down. Similarly, the drill rod 100 will also slide down relative to the movable supporting mechanism. The clamping force of the movable supporting mechanism is not enough to support the weight of the drill rod 100. Therefore, at this time, the drill rod 100 slides down by the weight from above, and the driving rod 101 of the drill rod 100 is located in the driving groove 32. At this time, the pull-out conveying plate 18 is reset under the action of the pull-out driving mechanism. During the process, the rack 33 will mesh with the driving teeth on the outside of the driving rod 101, and the rack 33 on the pull-out conveying plate 18 will mesh with the driving teeth to drive the driving rod 101 to rotate. After the driving rod 101 rotates, the drill rod 100 will also rotate. Due to the action of gravity, the bottom of the drill rod 100 to be installed will dock with the threaded connection head 102 of the drill rod 100 at the lower end. At this time, as the pull-out conveying plate 18 is reset, the drill rod 100 can be rotated relative to the bottom drill rod 100 under the support of the movable supporting mechanism. At this time, the two drill rods 100 can be threadedly connected, and can be manually connected later. However, if the reset driving force of the pull-out conveying plate 18 is very large, there is no need for later tightening, because the rotation direction of the punching mechanism is the same as the threaded engagement and sealing direction of the two drill rods 100, that is, as long as the punching mechanism rotates, the drill rods 100 are always rotating in the direction of thread locking. When the pull-out conveying plate 18 is reset, the driving rod 101 is separated from the driving groove 32, and the connection of the two drill rods 100 is completed. The reset ability of the pull-out conveying plate 18 is reasonably utilized. Therefore, the pull-out conveying plate 18 can convey the drill rods 100, and its reset force can also be used to complete the threaded connection of the two drill rods 100.

[0067] like Figure 10As shown, a plurality of drill rod 100 mounting holes are equidistantly provided on the pulling and conveying plate 18, and an O-ring is installed in each of the drill rod 100 mounting holes. The O-ring increases damping to prevent the drill rod 100 from sliding down immediately when it loses the support of the support cavity 24. After it is installed in the movable supporting mechanism, it begins to slide down slowly. Each drill rod 100 passes through the O-ring and makes the driving rod 101 and the threaded connector 102 of the drill rod 100 located on the upper end surface of the pulling and conveying plate 18, so that the driving rod 101 and the threaded connector 102 are both located in the accommodating cavity, as shown in FIG. Figure 7 As shown, the bottom of the drill rod 100 is horizontal and in contact with the support cavity 24 opened on the connecting plate for support. A layer of elastic rubber docking layer is fixedly provided at the bottom of the drill rod 100. When the upper and lower docking interfaces of the two drill rods 100 are used, the last driving force of the rack 33 and the driving rod 101 is used, that is, when the two are about to separate, the elastic rubber docking layer is compressed and elastically deformed, so that the drill rods 100 are better assembled and more firmly assembled.

[0068] like Figure 9 As shown, the movable supporting mechanism includes a movable plate 13 and a supporting clamping ring 15. Both sides of the movable plate 13 are slidably buckled into the sliding groove 31. A mounting opening 132 is provided on the movable plate on one side of the pulling and conveying plate 18. An elastic supporting clamping ring 15 is installed in the mounting opening 132. The supporting clamping ring 15 is located on one side of the drill rod 100 to form a trumpet-shaped bayonet. The trumpet bayonet makes it easier for the drill rod 100 to be buckled into the bayonet and fixed. The drill rod 100 to be installed is buckled into the supporting clamping ring 15 by using the pulling and conveying plate 18. The supporting clamping ring 15 is made of elastic metal parts, and its clamping force on the drill rod 100 is less than the gravity of the drill rod 100. After the drill rod 100 is buckled into the supporting clamping ring 15, it can be lowered by its own weight, so that the threaded connection hole 36 at the bottom of the drill rod 100 can be docked and supported with the threaded connection head 102 at the upper end of the bottom drill rod 100. The supporting clamping ring 15 has elastic deformation force, which can adapt to different drill rods 100 and has a certain clamping force on the installed drill rod 100, so as to achieve the purpose of stable support. When the drill rod 100 to be installed slides down, the drill rod 100 is not separated from the supporting clamping ring 15 and is still in a supporting state with the supporting clamping ring 15. At this time, the conveying plate 18 is pulled out to reset, and the drill rod 100 can be rotated in a circle in the supporting clamping ring 15. Figure 8 As shown, the threaded connection with the bottom drill rod 100 is completed in the supporting state, so that the upper and lower drill rods 100 are more accurately docked, no deviation occurs during the thread tightening process, and the thread engagement is smoother;

[0069] In order to allow the supporting clamp 15 to have a better retreat ability, in this embodiment, Figure 9As shown, a guide slot 131 is provided on each of the movable plates 13 on both sides of the mounting opening 132, and a guide plug plate 151 is provided on each side of the supporting clamp 15 at a position corresponding to the guide slot 131. The guide plug plates 151 are respectively inserted into the guide slots 131 on both sides. At the moment when the drill rod 100 is buckled into the supporting clamp 15, the drill rod 100 is used to open the bayonet so that the guide plug plate 151 can move in the guide slot 131. Limiting guide rods and limiting slide grooves 31 can be provided at the upper and lower ends of the guide rod and the upper and lower ends of the guide slot 131, so that the guide rod will not be separated from the guide slot 131.

[0070] like Figure 1 、 Figure 4 、 Figure 5 、 Figure 11 As shown, the linkage mechanism includes a telescopic drive rod, an air storage bag 30 and an ejection spring 12. The ejection spring 12 is respectively arranged in a slide groove 31 and is located on one side of the movable plate 13 of the movable supporting mechanism. The ejection spring 12 is used to eject the movable plate 13 and move the movable plate 13 toward the drill rod 100. When the ejection spring 12 is fully ejected, the movable plate 13 is located directly below the punching mechanism.

[0071] The telescopic driving rod is arranged on the other side of the movable plate 13, and the telescopic driving rod is connected to the air bag 30 through the air guide tube. When the air bag 30 is squeezed by the pulling and conveying plate 18, the telescopic driving rod is filled with gas in the air bag 30 and ejected. At this time, the ejected telescopic driving rod pushes the movable plate 13 to move toward the ejection spring 12. At this time, the ejection spring 12 is compressed, and the movable plate 13 is misaligned with the punching mechanism. The movable plate 13 is located at the farthest end of the pulling and conveying plate 18, that is, the entire movable supporting mechanism will not interfere with the punching operation of the punching mechanism. When the pulling and conveying plate 18 conveys the drill rod 100 and leaves the initial position, the squeezing force of the pulling and conveying plate 18 on the air bag 30 disappears, and the movable plate 13 is located at the farthest end of the pulling and conveying plate 18. The gas in the rod returns to the air storage bag 30, the telescopic driving rod is reset, the ejection force on the movable supporting mechanism disappears, and the movable supporting mechanism is ejected under the action of the ejection spring 12. At this time, the movable supporting mechanism is just located at the bottom of the punching mechanism. After the pull-out conveying plate 18 is reset, the pull-out conveying plate 18 will continuously squeeze the air storage bag 30 during the reset process. The air storage bag 30 is continuously pressurized, and the internal gas is continuously squeezed out into the telescopic driving rod. The telescopic driving rod is continuously ejected, thereby pushing the movable supporting mechanism to move along the slide groove 31. At this time, the ejection spring 12 at the other end of the movable supporting mechanism is compressed, and the movable supporting mechanism avoids the position of the punching mechanism, and the punching mechanism realizes normal operation.

[0072] The air storage bag 30 is installed in a connecting plate at the top, and the air storage bag 30 is located at the farthest end from the punching mechanism. The two sides of the pulling conveying plate 18 are respectively slidably assembled in the pulling grooves opened on both sides of the bottom of the connecting plate. The air storage bag 30 is installed in the pulling grooves. Figure 4 and Figure 11 shown.

[0073] Please continue reading Figure 4 and Figure 11 The pulling conveyor plate 18 is provided with a step surface 29 on each side of the air storage bag 30. One end of the air storage bag 30 is fixed to the pulling groove, and the other end is in contact with the step surface 29 on the pulling conveyor plate 18 for support. When the pulling conveyor plate 18 is reset, the pulling conveyor plate 18 squeezes the air storage bag 30, and the air guide tube is arranged in the wiring channel inside the walking mechanism;

[0074] Among them, the telescopic drive rod includes a telescopic tube 4 and a telescopic rod 11. A sealed air storage chamber is provided in the telescopic tube 4. A sealing piston is installed at one end of the telescopic rod 11 and is sealed into the air storage chamber. The air storage chamber is connected to the air storage bag 30 through an air guide tube. When the gas in the air storage bag 30 enters the air storage chamber, the telescopic rod 11 in the telescopic drive rod is pushed out, and the telescopic rod 11 pushes the movable supporting mechanism to slide along the slide groove.

[0075] In this embodiment, the two connecting plates include a first connecting plate 22 and a second connecting plate 23. The first connecting plate 22 is located at the upper end of the second connecting plate 23, and the pulling conveyor plate 18 is pulled and installed at the bottom position of the first connecting plate 22. The pulling drive mechanism is installed on the first connecting plate 22, and the support cavity 24 is formed on the second connecting plate 23.

[0076] Among them, Figure 2 and Figure 10As shown, the pulling and drawing drive mechanism includes a large-stroke driving cylinder 20, which is fixedly mounted on the upper end of the first connecting plate 22, a cylinder rod 28 of the driving cylinder 20, and a driving chute 26 penetrating the stroke path of the cylinder rod 28 of the first connecting plate 22. A driving block 27 is fixedly mounted on the cylinder rod 28, and the driving block 27 passes through the driving chute 26 to connect to the bottom pulling and conveying plate 18. The large-stroke driving cylinder 20 drives the pulling and conveying plate 18 to perform a reciprocating pulling and drawing action. Since the pulling and conveying plate 18 adopts a large-stroke cylinder to drive back and forth, the driving force is large, and the pulling and conveying plate 18 can be sufficient to buckle the drill rod 100 to be installed into the movable supporting mechanism, and when the pulling and conveying plate 18 is reset, There is enough force to squeeze the air bag 30, and the internal gas of the air bag 30 is squeezed into the telescopic drive rod by high pressure. The telescopic drive rod pushes the movable supporting mechanism to move in the direction away from the drill rod 100. When the pulling and conveying plate 18 is in the initial stage of resetting, it will drive the drill rod 100 to be installed to rotate. This process will not squeeze the air bag 30, because the blowing bag is installed at a position far away from the punching mechanism. Until the two drill rods 100 are threadedly assembled, the air bag 30 will be squeezed as the pulling and conveying plate 18 continues to reset. At this time, the squeezing force is used to separate the movable supporting mechanism from the installed drill rod 100. After separation, the punching mechanism can be opened to achieve punching, which is very convenient and does not require excessive human intervention during the entire process.

[0077] like Figure 2 and Figure 12 As shown, an assembly block 25 is provided on both sides of the connecting plate at the position opposite to the assembly groove 50. The cross-sections of the assembly block 25 and the assembly groove 50 are both T-shaped. Through the T-shaped structure, the connecting plate and the walking mechanism cannot be displaced in the left and right directions after installation. Screw holes can be provided at the positions of the walking mechanism corresponding to the assembly blocks 25. By tightening the screws, the displacement of the connecting plate in the length direction of the assembly groove 50 is limited. The disassembly and assembly method is simpler, and the disassembly and assembly efficiency is improved.

[0078] like Figure 1 As shown, in this embodiment, the punching mechanism includes a control host 21, a lifting mechanism, a rotary drive mechanism, and a rotary disk 16. A connecting shaft 17 is provided on the top of the rotary disk 16, and the other end of the connecting shaft 17 is fixedly mounted on the power output end of the rotary drive mechanism. The lifting mechanism is mounted on the control host 21, and the control host 21 is mounted on the upper mounting panel of the traveling mechanism. The rotary drive mechanism is mounted on the lifting mechanism.

[0079] The rotary drive mechanism includes a mounting plate 6, on which a reducer and a rotary drive motor 8 are mounted. The input end of the reducer is connected to the output shaft of the rotary drive motor 8, and the output end of the reducer is connected to the connecting shaft 17. The reducer and the rotary drive motor 8 are both arranged on the mounting plate 6, and the mounting plate 6 is mounted on the lifting mechanism and is driven to rise or fall by the lifting mechanism. The rotary drive mechanism and the lifting mechanism are both controlled by the control host 21.

[0080] The lifting mechanism can adopt a screw lifting mechanism, that is, it includes a screw motor 7, a fixed guide rail 5, a screw, etc. The screw motor 7 is installed on the top to drive the screw. The guide rail sliders can be installed at the positions of the fixed guide rail 5 at both ends of the mounting plate 6. The guide rail sliders are slidably installed on the screw. The screw lifting is an existing technology and will not be described in detail here. In this embodiment, the screw lifting mechanism is used to complete the lifting and drilling, and the drilling is completed by the rotation drive motor 8 of the drilling mechanism. The entire process is completed by electricity, which makes the entire pile driver miniaturized and particularly suitable for complex environments such as mountains.

[0081] The present invention innovatively divides the pile driver into two independent modules, namely the first traveling mechanism 1 and the second traveling mechanism 2. This split structure not only facilitates the transportation of the pile driver, but also reduces the environmental impact in specific areas such as mountainous areas, and reduces damage to trees and the surrounding natural environment.

[0082] By transporting them separately and independently, the pile driver can flexibly enter complex terrains such as mountainous areas. After entering the target area, the two modules can be quickly assembled to achieve precise construction at specific locations. At the same time, with the help of the crawler 19 structure, the pile driver has better terrain adaptability and can move flexibly in complex environments such as mountains.

[0083] In addition, the power of the entire traveling mechanism and the power of drilling are driven by electric motors. This structure not only enhances the environmental protection characteristics of the pile driver, but also promotes the miniaturization of the pile driver of the present invention, that is, a micro pile driver, making it more suitable for use in special occasions.

[0084] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
