Abstract
Description
Technical Field
[0001] This application relates to the field of building construction technology, and more specifically, to a quick docking device for building pile foundations. Background Technology
[0002] Pipe piles are prefabricated engineering piles used as foundation materials for buildings. Under specific geological conditions, they are driven into the ground by a piling machine and play a load-bearing role in buildings and structures. The main uses of pipe piles are twofold: one is to transfer the weight of the building above to the lower soil layer with high bearing capacity, improving the stability of the building; the other is to compact soft soil layers, thereby improving the bearing capacity of the foundation soil. For example, Chinese patent application number CN202121069821.2 describes a rapid docking and automatic welding device for foundation pipe piles, including a first pipe pile and a second pipe pile; the present invention includes a kit fitted onto the top of the surface of the first pipe pile. After the first pipe pile is installed, the second pipe pile is connected to the top of the first pipe pile. After the connection is completed, the motor drives the gear to rotate. The gear and the circular rack mesh to drive the sleeve to rotate. When the sleeve rotates, the bearing seat is set to maintain its stability during rotation. When the installation disc rotates, it drives the automatic electric welding machine to rotate and weld the joint between the first and second pipe piles. This is to solve the problem that the connection and fixation of pipe piles is mostly done manually for circumferential welding, which is inefficient, difficult to guarantee the uniformity of welding quality, and also poses a great danger and causes later harm to the human body.
[0003] However, the above solution still has certain drawbacks: First, the kit is an integral unit. After welding the first and second pipe piles, the kit is not easy to separate from the first and second pipe piles. This means that a new kit needs to be replaced every time the pipe piles are connected, which can easily lead to a waste of resources. Second, it is not convenient to quickly change welding machines of different power according to construction needs, and it is not easy to adapt to various welding scenarios, thus reducing its practicality.

After welding the first and second pipe piles, the kit is not easy to separate from the first and second pipe piles, which means that a new one needs to be replaced every time the pipe piles are connected, which easily leads to resource waste. Secondly, it is not convenient to quickly change welding machines of different power according to construction needs, and it is not easy to adapt to various welding scenarios, thus reducing the practicality of the device.

[0027] Please see Figure 1-4 This application provides a quick docking device for building pile foundations, including a connecting component 100 and a welding component 200.
[0028] Please see Figure 1-2 The connecting assembly 100 includes a first pipe pile 110, a second pipe pile 120, arc-shaped clamps 130, fasteners 140, fixing frames 150, and clamping seats 160. The second pipe pile 120 is disposed at one end of the first pipe pile 110. Both arc-shaped clamps 130 are in contact with the first pipe pile 110 and are connected by fasteners 140. Both fixing frames 150 are fixedly connected to the arc-shaped clamps 130. The clamping seats 160 are disposed on the fixing frames 150. On one side of the frame 150, the clamping seat 160 contacts the second pipe pile 120. The fastener 140 includes a bolt 141 and a nut 142. Both bolts 141 are connected through to both ends of the arc-shaped clamping plate 130. The nut 142 is threaded to the bolts 141 and contacts the arc-shaped clamping plate 130. The two arc-shaped clamping plates 130 can be fixed to the surface of the first pipe pile 110 by the cooperation of the bolts 141 and the nut 142, and can be easily disassembled.
[0029] In some specific implementations, a toothed plate 151 is provided on one side of the fixing frame 150. The toothed plate 151 can serve as a connection. The clamping seat 160 includes a vertical plate 161, a horizontal plate 162, a hydraulic cylinder 163, and a clamping plate 164. The horizontal plate 162 is fixedly connected to the vertical plate 161. The hydraulic cylinder 163 is located on one side of the horizontal plate 162, and the output end of the hydraulic cylinder 163 is connected through to one side of the vertical plate 161. The clamping plate 164 is fixedly connected to the output end of the hydraulic cylinder 163. The clamping plate 164 is in contact with the second pipe pile 120. The hydraulic cylinder 163 causes the clamping plate 164 to move. The two clamping plates 164 can clamp and fix the second pipe pile 120.
[0030] Please see Figure 1 , Figure 3 and Figure 4 The welding assembly 200 includes a movable base 210, a driving component 220, an electric welding machine 230, and an elastic bracket 240. The movable base 210 is slidably connected to the fixed frame 150. The driving component 220 is disposed on one side of the movable base 210 and is connected to the fixed frame 150 in a transmission manner. The elastic bracket 240 is fixedly connected to the electric welding machine 230 and is slidably engaged with the movable base 210. The movable base 210 includes a limiting plate 211, a limiting frame 212, and a support plate 213. The limiting frame 212 is fixedly connected to the limiting plate 211, and the support plate 213 is fixedly connected to the limiting plate 211. The limiting plate 211 can play a moving role, and the limiting frame 212 and the support plate 213 can play a connecting role.
[0031] In some specific implementations, the drive component 220 includes a motor 221 and a gear 222. The gear 222 is fixedly connected to the output end of the motor 221 and meshes with the gear plate 151. The motor 221 causes the gear 222 to rotate. The meshing of the gear 222 with the gear plate 151 allows the support plate 213, the limiting plate 211, and the limiting frame 212 to move. The elastic seat 240 includes a limiting block 241, an arc-shaped block 242, and a spring 243. The limiting block 241 is slidably connected to the limiting frame 212, and the two arc-shaped blocks 242 slide... Connected to both sides of the limiting block 241, the arc-shaped block 242 contacts the limiting frame 212. Two springs 243 are set on both sides of the limiting block 241 and are fixedly connected to the arc-shaped block 242. By pulling the limiting block 241, the groove squeezes the arc-shaped block 242, thereby causing the arc-shaped block 242 to move into the limiting block 241, causing the arc-shaped block 242 to be misaligned with the groove. Then the limiting block 241 can be removed from the limiting frame 212, and the welding machine 230 can be disassembled. Conversely, the operation can fix the welding machine 230.
[0032] The working principle of this rapid connection equipment for building pile foundations is as follows: First, the first pipe pile 110 and the second pipe pile 120 are connected. Bolts 141 and nuts 142 are used to fix two arc-shaped clamping plates 130 onto the surface of the first pipe pile 110. A hydraulic cylinder 163 moves a retaining plate 164, which clamps and fixes the second pipe pile 120, improving welding stability. A motor 221 rotates a gear 222, which meshes with a toothed plate 151, moving a movable seat 210. This allows two welding machines 230 to weld the connection between the first pipe pile 110 and the second pipe pile 120. The position of the two arc-shaped clamping plates 130 is adjusted by rotating them, enabling the welding machines 230 to weld the first pipe pile 110 and the second pipe pile 120. The second pipe pile 120 is fully welded at the connection point, while the arc-shaped clamp 130 is designed as a detachable split structure, which facilitates separation from the first pipe pile 110 after welding, reducing the frequency of replacement. By pulling the limiting block 241, the groove squeezes the arc-shaped block 242, causing the arc-shaped block 242 to move into the limiting block 241, resulting in misalignment between the arc-shaped block 242 and the groove. Subsequently, the limiting block 241 can be removed from the limiting frame 212, allowing the welding machine 230 to be disassembled. Conversely, the welding machine 230 can be fixed, facilitating the replacement of welding machines 230 with different power levels. This also facilitates the separation of the arc-shaped clamp 130 from the first pipe pile 110, and allows for quick replacement of welding machines 230 with different power levels according to construction needs, making it adaptable to various welding scenarios and improving practicality.
[0033] It should be noted that the specific models and specifications of the hydraulic cylinder 163, motor 221 and welding machine 230 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
[0034] The power supply and operating principle of the hydraulic cylinder 163, the motor 221, and the welding machine 230 are clear to those skilled in the art and will not be described in detail here.
