Description

Technical Field

[0001] The utility model relates to the technical field of prestressed pipe pile sinking equipment, in particular to a high-precision pile position positioning device for prestressed pipe pile sinking. Background Art

[0002] Prestressed pipe piles are a type of structural element commonly used in bridges, buildings, and foundation engineering. They apply prestress inside the pipe piles to give them a higher bearing capacity and stability. Pile sinking refers to an engineering method that sinks the pile body into the foundation or water to increase the bearing capacity or stability of the foundation. Prestressed pipe pile sinking refers to the use of prestressed pipe piles as sinking piles. By applying prestress, they have a higher bearing capacity and stability, and are used for foundation reinforcement or building support engineering technology. This method is often used in engineering projects that need to enhance the bearing capacity or stability of the foundation, such as bridges, high-rise buildings and other construction projects, to ensure the safety and stability of the structure. When sinking the pipe piles, a positioning device needs to be used to position them so that they can quickly enter the center of the sinking hole through hoisting.

[0003] The current positioning device generally performs rapid positioning through a frame, and the pipe pile is inserted into the center of the frame. When the diameters of the pipe piles are different, the frame cannot quickly position multiple pipe piles. A single-size frame can only be used for pipe piles with the same diameter, and the scope of application is small, resulting in limited use in a variety of projects. Since the fixed-size pipe pile positioning device may not be applicable to all situations, construction workers need to spend more time and energy to install and adjust the device, thereby limiting the speed and efficiency of construction; and in order to ensure accurate positioning, the existing positioning devices are generally fixed, which is very inconvenient to carry and move.

[0014] The difference from the prior art lies in that: the utility model sets a moving component, so that the positioning plate can be moved by the universal wheel, and the equipment can be moved more conveniently during work, thereby saving manpower and eliminating the need for manual handling. During work, the universal wheel can be retracted to make the positioning plate contact the ground, thereby increasing the friction force and ensuring the accuracy of positioning.

[0024] The embodiment provides a high-precision pile position positioning device for prestressed pipe pile sinking, such as Figures 1 to 4 As shown, it includes a positioning plate 1, a positioning hole 101 is opened in the center of the positioning plate 1, and a plurality of fixing holes 2 are arranged on the top of the positioning plate 1. When the positioning plate 1 is positioned, a positioning rod can be inserted through the fixing hole 2 to increase the stability of the positioning plate; a plurality of movable adjustment components 3 are arranged on the outer wall of the positioning plate 1, and the plurality of movable adjustment components 3 are evenly distributed around the positioning plate 1; the movable adjustment component 3 includes a fixing frame 301 fixedly connected to the outer wall of the positioning plate 1 and a universal wheel 302 rotatably mounted on the fixing frame 301, and the fixing frame 301 The upper part is rotatably connected with a rotating shaft 302, and the outer wall of the rotating shaft 302 is fixedly connected with a rotating support 303, and the universal wheel 302 is installed at the bottom of the rotating support 303; the fixed frame 301 is provided with an axial hole corresponding to the rotating shaft 302, and the rotating shaft 302 passes through the center of the axial hole, so that the rotating shaft 302 can rotate on the fixed frame 301, thereby driving the rotating support 303 to rotate, completing the adjustment of the universal wheel 304, and during subsequent processing, the universal wheel 304 can be rotated to a certain angle, thereby making it have no moving effect. A latch 305 is installed between the fixed frame 301 and the rotating support 303; both the fixed frame 301 and the rotating support 303 are provided with sockets corresponding to the latch 305, and the latch 305 passes through the center of the socket; the fixed frame 301 and the rotating support 303 can be fixed by the latch 305, so that it has strong installation stability, ensuring that the universal wheel 304 can support the positioning plate 1 to move. At the same time, when the universal wheel 304 rotates, the latch 305 can be inserted into the fixed frame 301 to limit the universal wheel 304 to keep it in a horizontal state, move the equipment to the installation location, move it by the universal wheel 304, pull out multiple latches 305 after arriving at the designated location, then rotate the universal wheel 304, and then insert the latch 305 again, so that the universal wheel 304 no longer has the moving effect, and the positioning plate 1 contacts the ground.

[0025] like Figure 2 , Figure 3 and Figure 4As shown, a plurality of positioning seats 4 are fixedly connected to the top of the positioning plate 1, and the plurality of positioning seats 4 are equidistantly distributed around the positioning hole 101 in a circular shape, and the top of each positioning seat 4 is inclined, and all are inclined downward in the direction of the positioning hole 101; so that after the pipe pile contacts the positioning seat 4, it will slide downward along the inclined surface of the positioning seat 4, thereby playing a positioning and guiding role in the installation of the pipe pile, so that it enters the center of the positioning hole 101, and then performs subsequent secondary positioning. A plurality of circumferentially arranged clamping and positioning components 5 are arranged on the top of the positioning plate 1, and the plurality of clamping and positioning components 5 are equidistantly distributed around the positioning hole with the positioning hole 101 as the center, and are arranged alternately with the positioning seats 4. Each set of clamping and positioning components 5 includes a hydraulic cylinder 501 fixedly connected to the top of the positioning plate 1, the piston end of the hydraulic cylinder 501 is adjacent to the positioning hole 101, and a positioning block 502 is fixedly connected to its piston end, and a limiting slide groove 503 corresponding to the hydraulic cylinder 501 is opened on the top of the positioning plate 1, and the limiting slide groove 503 is arranged along the telescopic path of the piston rod of the hydraulic cylinder 501 and leads to the positioning hole 101; a slide column 504 is slidably connected in the limiting slide groove 503, and the slide column 504 is fixedly connected to the positioning block 502 through a connecting block 505; the slide column 504, the positioning block 502 and the connecting block 505 are integrated Structure; the sliding column 504, the positioning block 502 and the connecting block 505 have a strong connection strength, so that the sliding column 504 and the connecting block 505 can have a good supporting effect on the positioning block 502. When the positioning block 502 is subjected to the reverse force of the pipe pile, it can maintain stability, thereby ensuring the accuracy of positioning. The multiple hydraulic cylinders 501 are started, and the driving distance of the multiple hydraulic cylinders 501 is the distance between the positioning block 502 and the inner wall of the positioning hole 101 plus the diameter difference between the pipe pile and the positioning hole 101. The multiple positioning blocks 502 clamp the pipe pile and position it, and then lower the pipe pile to make it enter the center of the countersink to complete the pile sinking operation.

[0026] like Figure 1 and Figure 3 As shown, infrared ranging sensors 6 are installed at the front and back of the inner wall of the positioning plate 1, and installation grooves are opened at the front and rear ends of the inner wall of the positioning plate 1, and the two infrared ranging sensors 6 are located in the center of the installation grooves; blocks can be placed at the front and back of the top of the countersink, so that the two infrared ranging sensors 6 can measure the distance between the inner wall of the positioning hole 101 and the baffle. When the measurement results of the two infrared ranging sensors 6 are infinitely close to the same, and the data results are the same as the radius difference between the countersink and the positioning hole 101, it means that the countersink and the positioning hole 101 are in a concentric state, and the subsequent pile sinking can be accurately positioned.

[0027] The working principle of the utility model is as follows: first, the equipment is moved to the installation site, and is moved by the universal wheel 304. After reaching the designated site, a plurality of pins 305 are pulled out, and then the universal wheel 304 is rotated, and then the pins 305 are inserted into the fixing frame 301 again, so that the universal wheel 304 no longer has the moving effect, the positioning plate 1 is in contact with the ground, and then it is placed on the top of the countersunk hole, and blocks are placed at the front and back of the top of the countersunk hole. Two infrared distance measuring sensors 6 test the distance between the inner wall of the positioning hole 101 and the baffle. When the two distances are close to the same and the data are close to the radius difference between the positioning hole 101 and the countersunk hole, After the positioning is completed, a hole is drilled downward into the fixing hole 2, and a wooden column is inserted into the center of the fixing hole 2 to complete the fixing. The pipe pile is then hoisted so that it is located on the top of the positioning plate 1, and then aligned with multiple positioning seats 4 for lowering. As the multiple inclined positioning seats 4 slide downward, the center of the positioning hole 101 is positioned, and then multiple hydraulic cylinders 501 are started. The driving distance of the multiple hydraulic cylinders 501 is the distance between the positioning block 502 and the inner wall of the positioning hole 101 plus the diameter difference between the pipe pile and the positioning hole 101. The multiple positioning blocks 502 clamp the pipe pile in position, and then the pipe pile is lowered to the center of the sinking hole to complete the pile sinking operation.
