Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a pipe pile joint positioning device. Background Art

[0002] Pipe pile connection refers to the process of connecting the top of the previous pipe pile and the lower end of the next pipe pile when the length of a single pipe pile does not meet the design specification requirements. For precast pile foundation projects, especially when hammer piles are used, the pile end connection adopts a lock-type connection. As long as the lock holes are aligned, the connection can be achieved, which improves the connection efficiency to a certain extent and has a positive driving effect on projects with tight construction schedules. However, for the lock-type connection, when the pipe piles are connected, it is necessary to ensure that each thread at the bottom of the upper pipe pile is aligned with the corresponding lock hole at the top of the lower pipe pile to ensure that the upper pipe pile falls into place. Since the pipe pile is usually lifted by the lifting equipment through the wire rope and connected with the lower pipe pile, the upper pipe pile is in a suspended state, and its own verticality is not easy to ensure, so it is difficult to complete the hole operation, especially the pipe pile itself is a cylindrical structure, and the circumferential position of the pipe pile is not easy to locate. In the prior art, there is a lack of corresponding pipe pile docking and positioning devices. Generally, the pipe piles are manually moved to adjust their positions, and workers are required to cooperate with the retracting and releasing of wire ropes for multiple times to make fine adjustments. This is not only inefficient and labor-intensive, but also causes the pipe piles to be suspended in the air for a long time, increasing safety risks.

[0003] Therefore, it is necessary to provide a docking positioning device for pipe pile connection, so as to improve the hole alignment efficiency when the pipe pile is connected with a lock type during the installation of the pipe pile wire rope, reduce labor intensity, and thus improve the overall efficiency of the pile connection construction, reduce the hanging time of the pipe pile, and improve construction safety.

[0006] Furthermore, a slide rail is fixedly connected to the top of the support, the slider is slidably mounted on the slide rail, and the driving member is a screw nut mechanism provided with the slide rail.

[0007] Furthermore, one end of the lead screw of the lead screw nut mechanism is fixedly connected to a hand wheel.

[0008] Furthermore, a plurality of vertically arranged mounting grooves are evenly distributed along the circumferential direction on the clamping surface of the positioning clamp block, a roller mounting plate is fixedly connected in the mounting groove, and a plurality of rollers are correspondingly mounted on each roller mounting plate in the form of a column.

After the adjustment and alignment, the upper pipe pile is lowered under the premise of keeping the positioning clamps clamped (the roller design allows the upper pipe pile to fall smoothly).

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] See also Figure 1-4 In this embodiment, a pipe pile connection and docking positioning device is disclosed, comprising:

[0025] A liftable base 1, wherein the liftable base 1 is provided with a first pipe pile through hole 1a for the pipe pile to pass through. The liftable base 1 may be lifted in any manner, such as a jack, etc. The overall height of the liftable base 1 may be adjusted by designing the liftable base 1. By providing the first pipe pile through hole 1a, it is ensured that the liftable base 1 can be sleeved on the outside of the pipe pile;

[0026] The turntable 2 is mounted on the base 1 in a driven rotation manner, and a second pipe pile through hole 201 for the pipe pile to pass through is provided at the center of the turntable 2. Here, the turntable 2 is preferably manually driven to rotate. By designing the second pipe pile through hole 201, it is ensured that the turntable 2 can be smoothly installed;

[0027] The positioning assembly 3 includes a support 301, a slider 302, a positioning clamp 303 and a driving member 304. The support 301 is fixed to the turntable 2. The slider 302 is arranged on the support 301 in a manner that it can be driven to slide with a single degree of freedom. The positioning clamps 303 of the two groups of positioning assemblies 3 are used to cooperate to form radial and circumferential limits on the pipe pile. The driving member 304 is used to drive the slider 302 to slide, and the clamping surface of the positioning clamp 303 is a cylindrical surface. The clamping surface of the positioning clamp 303 is provided with a plurality of parts that can roll in the vertical direction and are used to abut against the pipe pile. The roller 303a on the rotating disk 2; here, the positioning assembly 3 can rotate with the rotating disk 2, and the two sets of sliders 302 can complete the clamping of the pipe pile after sliding. The radial and circumferential limit of the clamped pipe pile relative to the positioning clamp 303 is inconvenient, and the circumferential angle position of the pipe pile can be fine-tuned by rotating the rotating disk 2, and the adjustment is convenient. The driving member 304 preferably adopts a screw nut mechanism with a self-locking function; by designing the roller, it is ensured that the positioning clamp 303 can be displaced relative to the pipe pile in the vertical direction when clamping. It can be understood that the roller is rolling friction, and rolling can occur under the premise that the clamping force is not large enough;

[0028] The above-mentioned pipe pile connection and docking positioning device can improve the hole alignment efficiency when the pipe pile adopts a lock-type connection, reduce labor intensity, and thus improve the overall efficiency of the pile connection construction, reduce the hanging time of the pipe pile, and improve the construction safety; specifically, the two sets of positioning clamps 303 can form an enclosure for the pipe pile, thereby completing the radial and circumferential angular position positioning of the pipe pile, and the height position of the positioning clamp 303 can be adjusted by the set liftable base 1 to ensure the pre-alignment of the positioning clamp 303 and the lower pipe pile 6 and the positioning during docking; after the two sets of positioning clamps 303 complete the clamping of the pipe pile, the turntable 2 can be rotated to Together, the upper pipe pile 7 is driven to make fine adjustments in the angle position so that the fasteners of the upper pipe pile 7 are aligned with the lock holes at the top of the lower pipe pile 6, which is convenient for adjustment and effectively reduces the labor intensity. After adjustment and alignment, the upper pipe pile 7 is lowered (the design of the roller 303a allows the upper pipe pile to fall smoothly) while keeping the positioning clamp 303 clamped. During the falling process, the position of the positioning clamp 303 can remain unchanged, so that the upper pipe pile 7 can fall into place at one time without repeatedly lifting the wire rope of the lifting equipment, which effectively improves the construction efficiency, thereby improving the overall efficiency of the pile connection construction, reducing the hanging time of the pipe piles, and improving the construction safety.

[0029] In this embodiment, the top of the support 301 is fixedly connected with a slide rail 301a, and the slider 302 is slidably installed on the slide rail 301a. The driving member 304 is a screw-nut mechanism for setting the slide rail 301a; the installation of the screw-nut mechanism is an existing structure, which can drive the slider 302 to slide, and will not be repeated here. Here, the support 301 is preferably a hollow pillar. The design of the slide rail 301a is conducive to the single free sliding of the slider 302. The screw-nut mechanism is adopted, the transmission is smooth and reliable, and has a self-locking function, which is conducive to completing the clamping of the positioning clamp 303 on the pipe pile.

[0030] In this embodiment, one end of the screw of the screw-nut mechanism is fixedly connected to a handwheel 304a; the design of the handwheel 304a facilitates driving the screw to rotate, which helps to further reduce labor intensity. At the same time, manually driving the slider 302 to slide is conducive to adjusting the position as needed, with high flexibility.

[0031] In this embodiment, a plurality of vertically arranged mounting grooves 303b are evenly distributed along the circumferential direction on the clamping surface of the positioning clamp 303, and a roller mounting plate 303c is fixedly connected to the mounting groove 303b, and a plurality of rollers 303a are correspondingly mounted on each roller mounting plate 303c in the form of a row; specifically, the mounting groove 303b radially penetrates the positioning clamp 303 along the positioning clamp 303, the roller mounting plate 303c is inserted into the mounting groove 303b from the outside, and the roller 303a is rotatably mounted on the roller mounting plate 303c; this structural design is conducive to completing the installation of the roller 303a, simplifying the structure, and ensuring the stable contact between the roller 303a and the pipe pile.

[0032] In this embodiment, the positioning clamp block 303 is an arc-shaped plate, and the entire plate is an arc-shaped plate, which is conducive to an overall lightweight design.

[0033] In this embodiment, the liftable base 1 includes a base plate 101 and a plurality of synchronous lifting cylinders 102 fixedly mounted on the base plate 101. The working end of the synchronous lifting cylinder 102 is fixedly connected to a support plate 102a for supporting the ground. Specifically, the base plate 101 is a rectangular plate, and there are four synchronous lifting cylinders 102, which are arranged at the four corners of the rectangular plate. The synchronous lifting cylinders 102 can be synchronous cylinders, hydraulic cylinders, electric cylinders, etc., as long as the synchronous lifting of the base plate 101 is ensured. In this structural design, the stable lifting of the base plate 101 is ensured by setting a plurality of synchronous lifting cylinders 102. The support plate 102a can ensure that the base plate 101 is stably supported after lifting, and increase the friction with the bottom surface to prevent the displacement of the base plate 101 in the water during the lifting process.

[0034] In this embodiment, universal casters 101a are provided at the bottom of the base plate 101, and there are four casters 101a here. The design of the universal casters 101a is conducive to the overall transportation and movement, and at the same time, it is conducive to the position movement of the base plate 101 when the positioning clamp 303 is pre-aligned with the lower pipe pile 6.

[0035] In this embodiment, the turntable 2 is connected to the base plate 101 through the turntable bearing 5. Specifically, the turntable 2 can be fixed to the inner ring of the turntable bearing 5 by bolts, and the base plate 101 can be fixed to the outer ring of the turntable bearing 5 by bolts. The turntable bearing 5 is cheap, easy to install and reliable.

[0036] In this embodiment, the bottom plate 101 is fixedly connected with lifting ears 101b, and there are four lifting ears 101b here. The design of the lifting ears 101b is conducive to the overall lifting installation.

[0037] In this embodiment, a quick clamp 4 is also included, which is fixedly installed on the liftable base 1 and is used to lock the turntable 2. The quick clamp 4 can be purchased directly on the market and is an existing part, so it is not described here in detail. By setting the quick clamp 4, the turntable 2 can be locked after it is rotated into place to prevent the turntable 2 from shaking. The quick clamp 4 is easy to operate.

[0044] S6: Raise the liftable base 1 and make the lower part of the positioning clamp 303 separate from the lower pipe pile 6 (see Figure 3 ), after the lower portion of the positioning clamp 303 is separated from the lower pipe pile 6, the circumferential angle position of the upper pipe pile 7 can be adjusted by rotating the turntable 2;

[0045] S7: adjusting the circumferential position (circumferential angle position) of the upper pipe pile 7 by rotating the turntable 2 so that the fastener at the bottom end of the upper pipe pile 7 is aligned with the lock hole at the top end of the lower pipe pile 6;

[0046] S8: Use the turntable clamping mechanism 4 to lock the position of the turntable 2 to prevent shaking and displacement;
