Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0035] The technical solution of the present invention is further described below with reference to the accompanying drawings.

[0036] like Figure 1-8 As shown, an automated positioning construction device for pile foundations of buildings in complex terrain includes a support platform 1, a shaft sleeve 2 inserted and connected to the middle of the support platform 1 and coaxially connected to the support platform 1, a pile foundation axis positioning mechanism 3 arranged at the upper end of the support platform 1, a protective shell 4 fixedly mounted on the upper end of the support platform 1 and sleeved on the outside of the pile foundation axis positioning mechanism 3, a spirit level 6 fixedly mounted on the upper end of the support platform 1, a control box 7 fixedly mounted on the bottom of the support platform 1, and an adaptive positioning mechanism 5 arranged on the outer surface of the support platform 1.

[0037] In this embodiment, the adaptive positioning mechanism 5 includes a plurality of support frames 51 connected to the outer surface of the support platform 1 in a circular array, an electric telescopic rod 52 fixedly connected to the support frame 51 and interlaced with the support frame 51, a support base plate 53 movably connected to the lower end of the electric telescopic rod 52 by a hinge, and a positioning unit 54 arranged on one side of the support base plate 53; the positioning unit 54 includes a ground nail 542 fixedly connected to one side of the support base plate 53, a control cover 541 fixedly connected to the upper end of the ground nail 542, and an anti-slip component 543 arranged in the ground nail 542.

[0038] Through the above scheme: first, the entire complex terrain building pile foundation automated positioning construction device is transported to the target construction site and placed in the center of the area to be constructed. Then, a command is issued through the control box 7 to drive the electric telescopic rod 52 on each support frame 51 to extend downward, driving the support base plate 53 connected to it by a hinge to contact the ground. The hinged structure enables the support base plate 53 to automatically fit the ground angle, thereby enhancing the contact stability. When the support base plate 53 is in full contact with the ground, the ground nail 542 is pressed into the ground. Next, after the equipment is stabilized, the operator uses the spirit level 6 installed on the upper end of the support platform 1 to check the level of the entire machine. If tilt is found, the telescopic length of the electric telescopic rod 52 at different positions can be adjusted to achieve fine-tuning of the posture of the support platform 1, so that it is in an ideal horizontal state, providing a basic guarantee for subsequent precise positioning.

[0039] In this embodiment, the anti-slip assembly 543 includes a No. 2 forward and reverse motor 5431 fixedly mounted on the upper end of the control cover 541, a driving bevel gear 5432 fixedly connected to the output end of the No. 2 forward and reverse motor 5431, two transmission bevel gears 5433 respectively meshed with the two sides of the driving bevel gear 5432, a transmission screw 5434 fixedly connected to one end of the transmission bevel gear 5433 and movably connected in the control cover 541, a movable plate 5435 threadedly connected to the transmission screw 5434 and slidably connected in the ground nail 542, and a plurality of anti-slip pins 5436 fixedly connected to the movable plate 5435 at equal longitudinal distances; the upper part of the movable plate 5435 extends into the slide groove of the control cover 541 and is slidably connected to the control cover 541; the anti-slip pins 5436 penetrate the outer surface of the ground nail 542 and are slidably connected to the ground nail 542; under normal conditions, the anti-slip pins 5436 can be completely retracted into the ground nail 542.

[0040] Through the above scheme: it is necessary to further stabilize the device, start the anti-slip component 543 in the positioning unit 54, that is, control the No. 2 forward and reverse motor 5431 to rotate, drive the bevel gear 5432 to rotate accordingly, and drive the transmission bevel gears 5433 on both sides to rotate synchronously, thereby rotating the transmission screw 5434, and then rotating the movable plate 5435 along the direction of the slide groove of the control cover 541 under the action of the thread, pushing the multiple anti-slip nails 5436 fixed on it to pass through the outer wall of the ground nail 542 and penetrate into the ground, forming a firm anchor, effectively preventing the device from being displaced or tipped over during operation, and greatly improving the construction safety and stability.

[0041] In this embodiment, the pile foundation axis positioning mechanism 3 includes a driving assembly 31 movably connected to the support platform 1, a plurality of supporting slides 32 arranged in an annular array and fixedly connected to the shaft sleeve 2, and a positioning assembly 33 slidably connected in the supporting slide 32 and transmission-connected to the driving assembly 31; the shaft sleeve 2 is an up and down through-structure; the protective shell 4 is coaxially arranged with the shaft sleeve 2, and the outer surface of the protective shell 4 is annularly provided with a plurality of avoidance grooves 41 communicating with the interior of the protective shell 4; the number of supporting slides 32 is equal to the number of avoidance grooves 41, and the position of the supporting slide 32 corresponds to the position of the avoidance grooves 41, and the positioning assembly 33 is slidably connected to the protective shell 4 through the avoidance grooves 41; the driving assembly 31 includes a movable connection to the upper end of the support platform 1 and is connected to the axis A transmission gear ring 311 is coaxially arranged in the sleeve 2, a driving gear 312 is movably connected to the upper end of the support platform 1 and meshed with the transmission gear ring 311, a forward and reverse motor 313 is fixedly connected to the lower end of the support platform 1 and fixedly connected to the driving gear 312, and multiple transmission gears 314 are arranged in a ring array and movably connected to the upper end of the support platform 1 and meshed with the transmission gear ring 311; the positioning assembly 33 includes a slide bar 332 slidably connected to the support slide 32, a support rod 331 fixedly connected to the lower end of the slide bar 332 and slidably connected to the shaft sleeve 2, a positioning plate 334 fixedly connected to the support rod 331 and located in the shaft sleeve 2, and a transmission rack 333 fixedly connected to the lower end of the support rod 331 and meshed with the transmission gear 314.

[0042] Through the above scheme: after the equipment is completely stable and in a horizontal state, the automatic positioning operation of the pile foundation axis is started. This process is completed by the pile foundation axis positioning mechanism 3. When the control system starts the forward and reverse motor 313, the motor output end drives the driving gear 312 to rotate, and the driving gear 312 is engaged with the transmission gear ring 311, thereby driving the transmission gear ring 311 to rotate coaxially around the shaft sleeve 2. At the same time, the transmission gear ring 311 is engaged with multiple transmission gears 314 around it, so that these transmission gears 314 rotate synchronously. A transmission rack 333 is engaged under each transmission gear 314, and the transmission rack 333 is fixedly connected to the support rod 331. As the transmission gear 314 rotates, the transmission rack 3 33 slides along the supporting slide 32, driving the supporting rod 331 and the slide bar 332 above it and the positioning plate 334 to move synchronously. Since the supporting slide 32 is fixedly connected to the shaft sleeve 2, and the positioning component 33 is slidably connected to the protective shell 4 through the avoidance groove 41, the positioning plate 334 can move accurately in the radial direction under the protection of the protective shell 4, thereby realizing accurate positioning of the pile foundation axis. The entire pile foundation axis positioning process is programmable and supports multi-point linkage and automatic calibration functions. It is suitable for circular, rectangular or other regularly arranged pile foundation layouts. At the same time, since there are multiple positioning components 33 and they are distributed in a ring, combined with the synchronous drive of the transmission system, it can achieve uniform force, rapid response and high-precision adjustment effects.

[0043] During the specific use of this embodiment, the entire complex terrain building pile foundation automatic positioning construction device is first transported to the target construction site and placed in the center of the area to be constructed. Since the construction environment is often complex terrain, such as hillsides, soft soil or uneven ground, it is necessary to give priority to starting the adaptive positioning mechanism 5 to ensure the stability of the equipment. The control box 7 issues a command to drive the electric telescopic rod 52 on each support frame 51 to extend downward, driving the support base plate 53 connected to it by a hinge to contact the ground. The hinge structure enables the support base plate 53 to automatically fit the ground angle, thereby enhancing the contact stability. When the support base plate 53 is fully in contact with the ground, the ground nail 542 is pressed into the ground as a preliminary fixing point. Subsequently, the positioning unit 54 is started. The anti-slip component 543 in the control unit controls the rotation of the No. 2 forward and reverse motor 5431, driving the bevel gear 5432 to rotate accordingly, driving the transmission bevel gears 5433 on both sides to rotate synchronously, thereby causing the transmission screw 5434 to rotate, and the movable plate 5435 moves along the direction of the slide groove of the control cover 541 under the action of the thread, pushing the multiple anti-slip nails 5436 fixed thereon to pass through the outer wall of the ground nail 542 and penetrate deep into the ground to form a firm anchor, effectively preventing the device from being displaced or tipped over during operation, greatly improving the construction safety and stability. Next, after the equipment is stabilized, the operator uses the spirit level 6 installed on the upper end of the support platform 1 to check the level of the entire machine. If tilt is found, the telescopic length of the electric telescopic rod 52 at different positions can be adjusted. The posture of the support platform 1 is fine-tuned to make it in an ideal horizontal state, providing a basic guarantee for subsequent precise positioning. After the equipment is completely stable and in a horizontal state, the automatic positioning operation of the pile foundation axis is started. This process is completed by the pile foundation axis positioning mechanism 3. When the control system starts the forward and reverse motor 313, the output end of the motor drives the driving gear 312 to rotate, and the driving gear 312 engages with the transmission gear ring 311, thereby driving the transmission gear ring 311 to rotate coaxially around the shaft sleeve 2. At the same time, the transmission gear ring 311 engages with multiple transmission gears 314 around it, so that these transmission gears 314 rotate synchronously. A transmission rack 333 is engaged under each transmission gear 314, and the transmission rack 333 is fixedly connected to the support rod 331. The transmission gear 314 rotates, and the transmission rack 333 slides along the support slide 32, driving the support rod 331 and the slide 332 above it and the positioning plate 334 to move synchronously. Since the support slide 32 is fixedly connected to the shaft sleeve 2, and the positioning component 33 is slidably connected to the protective shell 4 through the avoidance groove 41, the positioning plate 334 can move precisely in the radial direction under the protection of the protective shell 4, thereby realizing precise positioning of the pile foundation axis. The entire pile foundation axis positioning process is programmable and supports multi-point linkage and automatic calibration functions. It is suitable for circular, rectangular or other regularly arranged pile foundation layouts. At the same time, since there are multiple positioning components 33 and they are distributed in a ring, combined with the synchronous drive of the transmission system, it can achieve uniform force, rapid response, and high-precision adjustment effects.Finally, in order to ensure that the internal mechanical structure of the device is not affected by the harsh external construction environment, the protective shell 4 plays a key protective role. It is made of high-strength materials and has good waterproof and dustproof properties. At the same time, the multiple avoidance grooves 41 opened on the outer surface of the protective shell 4 provide the necessary movement channels for the positioning component 33, which not only ensures the structural sealing but also does not hinder the flexible operation of the components. In summary, the present device achieves stable support under complex terrain through the adaptive positioning mechanism 5, and combines the multi-point synchronous drive system of the pile foundation axis positioning mechanism 3 to achieve efficient and high-precision automatic positioning of the pile foundation axis, greatly improving construction efficiency and engineering quality, and has broad engineering application prospects.
