Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a steel pipe pile positioning and splicing device. Background Technology

[0002] Steel pipe piles, with their advantages of high strength, corrosion resistance, and flexible construction, have become an indispensable foundation component in modern civil engineering. Their applications cover multiple fields, including bridges, offshore wind power, ports, and high-rise buildings. When constructing steel pipe piles, it is necessary to connect and fix adjacent sets of piles, which requires the use of positioning and splicing devices.

[0003] Existing steel pipe pile positioning and splicing devices typically use multiple bolt holes at both ends of the steel pipe piles for bolt connection and fixation with adjacent steel pipe piles. During splicing, a crane is usually used to lift the upper steel pipe pile. The positioning and splicing device positions the upper and lower sets of steel pipe piles. If the connection holes of the two sets of steel pipe piles are not aligned during this process, they need to be lifted and adjusted again, which is time-consuming, prolongs the construction cycle, and reduces the efficiency of splicing. Furthermore, during the positioning of the steel pipe piles, the device usually has multiple cylinders arranged in a ring around the outside of the steel pipe pile, simultaneously driving the clamping blocks to clamp and position the steel pipe pile. The multiple sets of cylinders increase the manufacturing cost of the device. At the same time, due to variations in the manufacturing environment and materials, the power of the cylinders varies. This difference may lead to inconsistent output forces of each cylinder when simultaneously driving the clamping blocks, thus affecting the stability of the positioning and causing deviations during the connection of the steel pipe piles. Utility Model Content

[0004] The purpose of this utility model is to provide a steel pipe pile positioning and splicing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel pipe pile positioning and splicing device, comprising:

[0006] A first connecting frame, a second connecting frame fixedly connected to the top of the first connecting frame, a fixed frame slidably connected to the bottom of the second connecting frame, a scaffold installed at the bottom of the first connecting frame, and a movable component provided on the outside of the fixed frame;

[0007] A drive assembly is disposed inside the first connecting frame, and a transmission assembly is disposed inside the drive assembly;

[0008] The swing assembly is located outside the transmission assembly, and there are two sets. Each set of the swing assembly has a clamping block for positioning the steel pipe pile on its outer side. The clamping block has a limiting assembly to improve its movement stability on its outer side.

[0009] An adjustment component is located at the bottom of the fixed frame, and two sets of rotating components are provided on the outer side of the adjustment component;

[0010] A connecting shaft is located inside the rotating assembly, and a transmission wheel is fixedly connected to the outside of the connecting shaft. A rubber sleeve is fitted on the outside of the transmission wheel.

[0012] Preferably, the swing assembly includes a rotating shaft that rotates on the inner wall of the first connecting frame, and a swing rod is fixedly connected to the outer side of the rotating shaft.

[0013] Preferably, the transmission assembly includes an inclined groove formed in the inner wall of the adjustment frame, and a lever is slidably connected to the inner wall of the inclined groove.

[0014] Preferably, the limiting component includes a connecting block fixed to the outside of the clamping block, and a guide groove is provided on the outside of the first connecting frame, and the outside of the connecting block is slidably connected to the inside of the guide groove.

[0015] Preferably, the adjustment assembly includes a motor fixed to the bottom of the mounting frame, the output end of the motor is provided with a screw, and the outer side of the screw is threaded with four sets of threaded blocks.

[0016] Preferably, the rotating assembly includes a toothed plate fixed to the outside of the threaded block, a gear being meshed with the outside of the toothed plate, and the inner wall of the gear being fixedly connected to the outside of the connecting shaft.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention uses a cylinder piston rod to drive an adjusting frame forward. This positional change causes a lever to slide into one end of an inclined groove, altering the position of one end of a swing rod. The swing rod then rotates around a pivot, causing the other end to tighten the clamping block inwards, thus clamping and positioning the steel pipe pile. Positioning the steel pipe pile is achieved by driving the clamping block with a single cylinder, reducing manufacturing costs and improving positioning stability. Kinetic energy is transmitted through a connecting shaft, driving the transmission wheel to rotate. Multiple pulleys are rotatably connected to the inner wall of the clamping block located inside the second connecting frame. The friction between the rubber sleeve and the surface of the steel pipe pile allows the upper group of steel pipe piles to rotate smoothly. Movement stops once the holes are aligned, eliminating the need for re-hoisting and adjustment, reducing adjustment time, shortening the construction cycle, and improving splicing efficiency.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 As shown, a steel pipe pile positioning and splicing device includes a first connecting frame 1, a second connecting frame 2 fixedly connected to the top of the first connecting frame 1, a fixed frame 4 slidably connected to the bottom of the second connecting frame 2, and a scaffold 3 installed at the bottom of the first connecting frame 1 for supporting the device. A moving component 15, composed of hydraulic cylinders, is provided on the outer side of the fixed frame 4 for driving the fixed frame 4 to move back and forth. A driving component 5 is provided on the inner side of the first connecting frame 1, and a transmission component 7 is provided on the inner side of the driving component 5. Two swing components 6 are provided on the outer side of the transmission component 7, and each set of swing components 6 has a clamping block 8 for positioning the steel pipe pile on its outer side. The second connecting frame 2 also has a driving component 5, a swing component 6, a transmission component 7, a clamping block 8, and a limiting component 9 on its inner side. The difference is that the clamping block 8 located on the inner side of the second connecting frame 2 has multiple pulleys rotatably connected to its inner wall to ensure that the steel pipe pile can still be driven to rotate laterally after being clamped and positioned. A limiting component 9 is provided on the outer side of the clamping block 8 to improve its movement stability.

[0026] An adjusting component 10 is located at the bottom of the fixed frame 4. Two sets of rotating components 11 are arranged on the outer side of the adjusting component 10. A connecting shaft 12 is located inside the rotating components 11. A transmission wheel 13 is fixedly connected to the outer side of the connecting shaft 12. The two sets of transmission wheels 13 will rotate in the same direction. A rubber sleeve 14 is fitted on the outer side of the transmission wheel 13. The rubber sleeve 14 is used to enhance the friction between the transmission wheel 13 and the surface of the steel pipe pile, ensuring that the steel pipe pile can be driven to rotate.

[0027] The drive assembly 5 includes a cylinder 51 fixed to the inner wall of the first connecting frame 1. The piston rod of the cylinder 51 is fixedly connected to an adjusting frame 52. When the piston rod of the cylinder 51 moves, it will drive the adjusting frame 52 to move back and forth.

[0028] The swing assembly 6 includes a rotating shaft 61 that rotates on the inner wall of the first connecting frame 1. A swing rod 62 is fixedly connected to the outer side of the rotating shaft 61. When the swing rod 62 rotates around the rotating shaft 61, its other end will drive the clamping block 8 to adjust the spacing.

[0029] The transmission assembly 7 includes an inclined groove 72 formed on the inner wall of the adjusting frame 52. The inner side of the inclined groove 72 is an inclined groove facing forward and backward. A lever 71 is slidably connected to the inner wall of the inclined groove 72. The lever 71 is fixed to one end of the swing rod 62. When the adjusting frame 52 moves, the lever 71 slides along the inner side of the inclined groove 72 by changing its position, thereby changing the position of one end of the swing rod 62.

[0030] The limiting component 9 includes a connecting block 91 fixed to the outside of the clamping block 8. A guide groove 92 is provided on the outside of the first connecting frame 1. The outside of the connecting block 91 is slidably connected to the inside of the guide groove 92. When the clamping block 8 moves, it will drive the connecting block 91 to slide along the inside of the guide groove 92. The guide groove 92 will restrict the movement path of the connecting block 91, so that the clamping block 8 moves along a parallel trajectory.

[0031] The adjustment assembly 10 includes a motor 101 fixed to the bottom of the mounting bracket 4. The output end of the motor 101 is provided with a screw 102. Four sets of threaded blocks 103 are threadedly connected to the outer side of the screw 102. When the motor 101 starts, it drives the screw 102 to rotate, and the threaded blocks 103 move along the axial direction of the screw 102. The top of the threaded blocks 103 is slidably connected to the bottom of the mounting bracket 4, which can ensure the stability of the threaded blocks 103 during movement.

[0032] The rotating assembly 11 includes a toothed plate 111 fixed to the outside of the threaded block 103. A gear 112 is meshed with the outside of the toothed plate 111. The inner wall of the gear 112 is fixedly connected to the outside of the connecting shaft 12. When the toothed plate 111 moves, it drives the gear 112 to rotate accordingly. The rotation direction of the gear 112 is related to the movement direction of the toothed plate 111.

[0033] Working Principle: In use, the device is first fixed at the construction site. The height of the first connecting frame 1 is adjusted by adding scaffolding 3. After preparation, a crane is used to move the steel pipe piles into the device. When the two sets of steel pipe piles are spliced, the two sets of drive components 5 located inside the first connecting frame 1 and the second connecting frame 2 are started simultaneously. The piston rod of the cylinder 51 drives the adjusting frame 52 to move forward. Through the change of position, the lever 71 slides into one end of the inclined groove 72, thereby changing the position of one end of the swing rod 62, so that the swing rod 62 rotates around the pivot 61. Its other end drives the clamping block 8 to tighten inward, clamping and positioning the upper and lower steel pipe piles. It is necessary to align the two sets of... When positioning the bolt holes of the steel pipe pile, the moving component 15 first pushes the fixing frame 4 to move. The movement stops when the rubber sleeve 14 is attached to the outside of the steel pipe pile. Then, the motor 101 starts and drives the screw 102 to rotate, causing the four sets of threaded blocks 103 to move simultaneously along their axial direction, driving the two sets of toothed plates 111 to move in the same direction, driving the gears 112 connected to each other to rotate synchronously. The kinetic energy is transmitted through the connecting shaft 12, driving the transmission wheel 13 to rotate. Since the inner wall of the clamping block 8 located inside the second connecting frame 2 is rotatably connected to multiple pulleys, the friction between the rubber sleeve 14 and the surface of the steel pipe pile allows the upper set of steel pipe piles to smoothly achieve rotational displacement. The movement stops when the holes are aligned.
