Description

Technical Field

[0001] This invention relates to the field of pile driver technology, and in particular to an integrated pile driving machine capable of both internal and external pile driving. Background Technology

[0002] Piling machines are large, with lengths and widths exceeding ten meters and weights exceeding two hundred tons. Their columns can reach heights of forty to fifty meters. Therefore, maintaining the overall center of gravity balance is a crucial design consideration. To achieve this balance, most existing piling machines use internal pile driving, meaning an operating port is located in the center of the chassis for drilling and pile driving. Concentrating components in the center of the chassis helps maintain overall stability during operation and better protects components from unnecessary collisions. Every project typically has several edge piles near roads or corners. While internal pile driving machines offer more advantages, they cannot drive edge piles. The number of edge piles in each project is small, or even nonexistent. Dedicatedly configuring a separate edge pile driving machine is not only expensive but also requires transporting an additional piece of equipment, significantly increasing construction costs.

[0003] This case arose in order to resolve the aforementioned issues. Summary of the Invention

[0027] A further improvement is that the rotation drive component is a motor, the motor housing is fixedly mounted on the track seat, and the rotation shaft of the motor is fixedly connected to the rotation shaft of the track drive wheel.

[0028] By adopting the aforementioned technical solution, the beneficial effects of the present invention are:

[0029] 1. The integrated pile driver in this case can be used for both internal and external pile planting. The chassis has sufficient space in the middle to accommodate the static pressure pile driver and allow for its sliding movement. However, it's impossible to clamp pipe fittings on the outer side of the chassis using a static pressure pile driver. Firstly, this would increase the chassis length, affecting the transport and movement of the pile driver. Secondly, the weight of the uprights already requires a counterweight at the other end of the chassis for balance; adding a static pressure pile driver on the outer side would require adding a counterweight of the same weight at the other end, necessitating a redesign of the chassis strength and the load-bearing capacity of the walking mechanism. Therefore, this case utilizes a pile clamping box on the outer side of the chassis to achieve external pile clamping, minimizing the added weight to the chassis while still facilitating pipe clamping and welding. Furthermore, the pile clamping box moves away from and into the borehole by side rotation, requiring minimal movement space and better adapting to the confined space of side piles. The pile clamping box can be disassembled when only internal pile driving is required. The telescopic rod of the second telescopic component, which drives the rotation of the pile clamping box, can be fixed to the chassis side via a third hinge seat, which helps protect the second telescopic component during pile driver operation. Alternatively, the pile clamping box and the telescopic rod of the second telescopic component can be fixed together to the side of the chassis for easy activation of the pile clamping box.

[0030] 2. In this case, two sliding channels are set on the lower surface of the chassis. Sliding tubes are slidably installed in the sliding channels. Both ends of the sliding tubes are equipped with detachable connectors. The bidirectional sliding of the sliding tubes can assist in the connection between the first drill rod and the second drill rod when drilling internally, and can also assist in the connection between the drill rod and the second drill rod when drilling externally. At the same time, it can be hidden at the bottom of the chassis when not in use, which can well adapt to the internal and external pile planting in this case.

[0031] 3. In this case, during drilling, the lifting mechanism drives the sealing cylinder to insert into the ground and surround the borehole. This allows the drilling mud from the first or second drill rod to rise along the lifting cylinder under the seal of the sealing cylinder, preventing it from accumulating at the borehole. The height difference between the upper end of the lifting cylinder and the sealing guide plate prevents mud from accumulating at the upper end of the lifting cylinder. Under the sealing and guiding effect of the sealing guide plate, all the mud enters the mud discharge trough. The inclined design of the sealing guide plate further improves flow guidance, preventing mud from spreading on the ground and affecting construction. The mud is then transported to the outside of the piling machine by the auger for centralized processing. The mud discharge box, mud discharge trough, and mud discharge conveyor are all open structures, facilitating mud cleaning.

[0032] The upward sliding mechanism between the sealing cylinder and the lifting cylinder can adapt to ground surfaces with varying heights and allows for control of the sealing cylinder's insertion depth, ensuring a tight seal between the bottom of the sealing cylinder and the drilled hole. The sealing cylinder is driven linearly up and down via a lifting mechanism, significantly simplifying the drive structure and improving drive efficiency.

[0033] 4. The traveling mechanism in this case has two modes of movement: one is the traditional mode of movement using a roadbed plate sliding motion, and the other is a mode of movement using a combination of a roadbed plate and tracks. Both modes can achieve forward and backward movement, as well as left and right movement. In the mode of movement using tracks and roadbed plates, the roadbed plate and tracks complement each other. The tracks can compensate for the low walking efficiency of the roadbed plate, improving the overall walking efficiency of the equipment. The roadbed plate can compensate for the insufficient stability of the tracks, increasing the overall stability of the piling machine during operation. Through the cooperation of tracks and roadbed plates, both walking efficiency and stability requirements are improved. Attached Figure Description

[0061] How to use an integrated pile-planting machine capable of both internal and external pile planting:

[0062] During the drilling of the internal pile, the first drill rod is located at the operating port 13 of the chassis 10 to drill into the bottom surface. When connecting the first and second drill rods to increase the drilling depth, the first telescopic component drives the sliding tube 19 to slide towards the operating port 13 until the disassembly joint is engaged under the flange at the upper end of the first drill rod, supporting the flange. Then, the first drill rod is detached from the first power head, the column 11 rotates, and the second power head and the second drill rod are rotated to above the first drill rod. After the lower end of the second drill rod is connected to the upper end of the first drill rod, the first telescopic component drives the sliding tube 19 to reset and hide under the chassis 10. After drilling is completed, the static pressure pile driver moves above the borehole to clamp the pipe fittings for pile installation. The clamping of the static pressure pile driver facilitates manual welding connection of the pipe fittings.

[0063] During external pile drilling, the first drill rod is positioned above and to the left of the chassis 10. When connecting the first and second drill rods to increase the drilling depth, the first telescopic component drives the sliding tube 19 to slide to the left of the chassis 10 until the disassembly connector engages below the flange at the upper end of the first drill rod, supporting the flange. Then, the first drill rod is detached from the first power head, and the column 11 rotates, rotating the second power head and the second drill rod above the first drill rod. After the lower end of the second drill rod is connected to the upper end of the first drill rod, the first telescopic component drives the sliding tube 19 to reset and hide below the chassis 10. After drilling is complete, the second telescopic component 34 drives the pile clamping box 24 to rotate around the hinge shaft 28 to above the borehole. The disengagement drive component 33 drives the upper connecting shaft 29 and the lower connecting shaft 30 to simultaneously insert into the first mounting lug 31 and the second mounting lug 32, completing the restrictive connection between the pile clamping box 24 and the chassis 10, thus restricting the rotation of the pile clamping box 24. The clamping drive unit 27 drives the clamping block 25 to move horizontally towards the center of the clamping box 24 or away from the center of the clamping box 24 to clamp the pipe fitting, which facilitates manual welding connection of the pipe fitting.

[0064] When the pile clamping box 24 is not needed, it can be removed from the chassis 10. After removal, the telescopic rod of the second telescopic member 34 can be hinged to the third hinge seat 37, bringing the second telescopic member 34 close to the chassis 10. This helps protect the second telescopic member 34 and prevents it from being damaged by impacts with other hard objects during chassis 10 movement. Alternatively, the telescopic rod of the second telescopic member 34 and the pile clamping box 24 can be connected together to the third hinge seat 37, which does not affect the external drilling and allows the pile clamping box 24 to be used immediately after completion.

[0065] During internal drilling, the lifting component 49 drives the sealing cylinder 48 to insert into the ground, allowing the drilling mud produced by the first or second drill rod to rise along the lifting cylinder 39 under the seal of the sealing cylinder 48. The mud then falls from the upper end of the lifting cylinder 39 to the sealing guide plate 41, and along the sealing guide plate 41 into the mud discharge trough 40. Under the action of the spiral rod 44, the mud enters the mud discharge conveying channel 42 and is discharged from the mud discharge port 46. Thanks to the sealing cylinder 48 and the sealing guide plate 41, the mud will not spill onto the ground or spread outwards, preventing mud accumulation below the chassis 10 from affecting the piling machine's operation. Both the mud discharge trough 40 and the mud discharge conveying channel 42 are open at the top, facilitating cleaning.

[0068] The walking drive device includes a groove 66 formed from top to bottom on the first road base plate 79 or the second road base plate 80, and two sets of pulley seats 67 slidably disposed in the groove 66. The groove 66 is provided with a guide rail that cooperates with the pulleys of the pulley seats 67.

Both ends of the linkage bar 69 are respectively connected to the pulley seats 67. The lower end of the first support column 57 or the second support column 58 is disposed on the pulley seat 67. The first support column 57 and the second support column 58 are hydraulic cylinders. The cylinder body of the hydraulic cylinder is vertically fixedly installed on the chassis 10.
