Description

Technical Field

[0001] This application relates to the field of pile foundation construction technology, and in particular to a rapid positioning device for pile protection. Background Technology

[0002] In pile foundation construction, the installation of the casing is a crucial first step in the construction of bored piles. The casing's function is to locate the center of the pile, protect the borehole opening from collapse, and maintain the mud head within the hole. Therefore, the accurate positioning of the casing's center directly determines the accuracy of the pile location, thus affecting the overall quality of the project. Currently, the commonly used casing positioning method on construction sites relies on the traditional "string method" (or "cross-shaped method"). While this method is simple to operate, it has the following significant shortcomings:

[0003] 1. Cumbersome operation and low efficiency: Traditional wire positioning requires repeated adjustment of the wire position, especially during the installation and resetting of the protective sleeve, which requires multiple wire pulling and disassembly, making the process complicated, time-consuming and labor-intensive;

[0004] 2. Susceptible to environmental influences: Construction sites often have interference factors such as wind, vibration, and personnel movement, which can easily cause the guy wire to deviate, resulting in a decrease in positioning accuracy;

[0005] 3. Significant repetitive work: During the hoisting, positioning, and adjustment of the casing, it is often necessary to repeatedly dismantle and re-lay out the casing lines, which not only increases the workload but also easily introduces human error.

[0006] Although some positioning aids exist in the existing technology, such as adjustable brackets or simple clamping devices, their structures are complex, their adjustment range is limited, or they cannot adapt to casings of different diameters, making it difficult to apply them widely in actual construction. Utility Model Content

[0007] The purpose of this invention is to provide a rapid positioning device for protective piles, thereby solving the problem of low efficiency in positioning the center of the protective casing during pile foundation construction.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a rapid positioning device for retaining piles, comprising four arc-shaped panels. A connecting seat is threadedly installed inside the outer side of the arc surface of each panel. A long threaded rod is installed inside the connecting seat via a bearing. A cross tube is threadedly connected to the outer side of the long threaded rod. An adjusting seat is fixedly connected to the lower outer side of the cross tube. A guide rod is slidably connected inside the adjusting seat. A supporting base plate is fixedly connected to the lower end of the guide rod. A locking mechanism is provided on the supporting base plate. A short threaded rod is installed inside the upper end of the supporting base plate via a bearing. An internally threaded tube is fixedly installed inside the adjusting seat.

[0009] Preferably, an adjustment knob is fixedly connected to the end of the long threaded rod away from the connecting seat, and the four arc panels are spliced ​​together to form a positioning ring. The ring formed by the four arc panels can be fitted onto the outside of the protective sleeve to position the protective sleeve.

[0010] Preferably, the internally threaded tube and the short threaded rod are connected by threads, and a drive handwheel is fixedly connected to the upper end of the short threaded rod, which can drive the short threaded rod to rotate.

[0011] Preferably, the locking mechanism includes a locking wheel, a locking wheel is fixedly connected to the lower outer side of the short threaded rod, a fixing plate is fixedly connected to the upper end of the support base plate, two symmetrically distributed connecting rods are slidably connected inside the fixing plate, a locking frame is fixedly connected to the end of the connecting rod near the locking wheel, a support spring is provided on the outer side of each of the two connecting rods, and the fixing plate can guide the movement of the connecting rods.

[0012] Preferably, the outer side of the locking wheel has multiple locking grooves arranged in a ring, and the locking frame engages with the locking grooves of the locking wheel, so that the locking frame can lock the short threaded rod through the locking wheel.

[0013] Preferably, one end of the support spring is fixedly connected to the fixing plate, and the other end of the support spring is fixedly connected to the locking frame. The support spring can support the locking frame through its elastic force.

[0014] Preferably, a pull ring seat is fixedly connected to the end of the connecting rod away from the locking frame. The pull ring seat is fixedly connected to the fixing plate, and the pull ring seat can drive the locking frame to move through the connecting rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This application uses an adjustable positioning ring to directly clamp the casing and a cross tube for visual alignment and fine-tuning, eliminating the tedious steps of repeatedly pulling and unpulling wires in traditional methods. It simplifies the complex spatial positioning problem into a rapid centering operation on this device, with smooth process connections, significantly reducing manpower and time costs, improving construction efficiency, and the positioning benchmark is not affected by environmental factors such as wind and vibration. It overcomes the accuracy loss problem caused by the flexible swaying of the wire in the traditional wire method, providing unprecedented stability for casing installation.

[0017] 2. This application adds a short threaded rod, an adjusting seat, and a locking mechanism to the cross tube. The independent height adjustment mechanism enables it to cope with uneven construction ground. The entire device has a reasonable structure and is easy to operate. Ordinary workers can master it after simple training, which lowers the technical threshold and makes positioning more convenient. Attached Figure Description

A connecting seat 2 is threadedly installed inside the outer side of the arc surface of the arc-shaped panel 1. A long threaded rod 3 is installed inside the connecting seat 2 via a bearing. A cross tube 5 is threadedly connected to the outer side of the long threaded rod 3. An adjusting seat 6 is fixedly connected to the lower outer side of the cross tube 5. A guide rod 7 is slidably connected inside the adjusting seat 6. A support base plate 8 is fixedly connected to the lower end of the guide rod 7. A locking mechanism 9 is provided on the support base plate 8. A short threaded rod 10 is installed inside the upper end of the support base plate 8 via a bearing. An internally threaded tube 11 is fixedly installed inside the adjusting seat 6.

[0026] Please see Figure 1-5An adjustment knob 4 is fixedly connected to the end of the long threaded rod 3 away from the connecting seat 2. Four arc panels 1 are spliced ​​together to form a positioning ring. The ring formed by the four arc panels 1 can be fitted onto the outside of the protective sleeve to position the protective sleeve. The internal threaded tube 11 is connected to the short threaded rod 10 by threads. A drive handwheel 12 is fixedly connected to the upper end of the short threaded rod 10. The drive handwheel 12 can drive the short threaded rod 10 to rotate.

[0027] Please see Figure 1-5 The locking mechanism 9 includes a locking wheel 91. The lower outer side of the short threaded rod 10 is fixedly connected to the locking wheel 91. A fixed plate 92 is fixedly connected to the upper end of the support base plate 8. Two symmetrically distributed connecting rods 93 are slidably connected inside the fixed plate 92. A locking frame 94 is fixedly connected to the end of each connecting rod 93 near the locking wheel 91. Support springs 96 are provided on the outer sides of both connecting rods 93. The fixed plate 92 guides the movement of the connecting rods 93. Multiple annularly distributed locking grooves are provided on the outer side of the locking wheel 91. The locking frame 94 engages with the locking groove of the locking wheel 91. The locking frame 94 can lock the short threaded rod 10 through the locking wheel 91. One end of the support spring 96 is fixedly connected to the fixing plate 92, and the other end of the support spring 96 is fixedly connected to the locking frame 94. The support spring 96 can support the locking frame 94 through its elasticity. The end of the connecting rod 93 away from the locking frame 94 is fixedly connected to the pull ring seat 95. The pull ring seat 95 is fixedly connected to the fixing plate 92. The pull ring seat 95 can drive the locking frame 94 to move through the connecting rod 93.

[0028] The specific implementation process of this utility model is as follows: In use, multiple arc panels 1 are combined. Then, construction personnel can use measuring equipment such as a total station to place the positioning ring of the combined arc panels 1 at a predetermined position. Then, the pull ring seat 95, through the connecting rod 93, drives the locking frame 94 to move and compresses the support spring 96. When the locking frame 94 disengages from the locking wheel 91, the limiting of the locking wheel 91 and the short threaded rod 10 can be released. Then, the short threaded rod 10 is driven to rotate by the drive handwheel 12. During the process, the position and height of the adjusting seat 6 and the cross tube 5 can be adjusted. After the adjustment is completed, the pull ring seat 95 is released and the support spring 96 is reset. The support spring 96 can drive the locking frame 94 to engage with the locking groove inside the locking wheel 91 through the elastic force, which can complete the limiting of the locking wheel 91 and the short threaded rod 10, making the positioning ring more stable. After adjusting the four angles respectively, the adjusting knob 4 can be rotated. The adjusting knob 4 can be adjusted through the threaded engagement with the cross tube 5 to make the positioning more accurate.

[0029] The adjustable positioning ring formed by multiple arc panels 1 directly clamps the protective cylinder, and the cross tube 5 is used for visual alignment and fine adjustment. This eliminates the tedious steps of repeatedly pulling and untying wires in traditional methods, simplifying the complex spatial positioning problem into a quick centering operation on this device. The process is seamless, significantly reducing manpower and time costs and improving construction efficiency.
