Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an adjustable building pile foundation positioning device. Background Technology

[0002] In the construction process, pile foundations are the foundation of each building. Accurate pile foundation positioning is the key to ensuring construction quality and project safety. Therefore, no operation that may affect stability can be carried out during pile foundation construction. However, the existing pile foundation positioning devices have low stability due to uneven ground at the construction site, and they cannot be adjusted according to actual construction needs and a series of factors such as pile height during pile foundation positioning, resulting in low positioning accuracy.

[0003] Therefore, how to realize an adjustable pile foundation positioning device is a technical problem that needs to be solved. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable building pile foundation positioning device. The U-shaped base, which can be longitudinally adjusted according to the actual diameter of the pile foundation, and the horizontally adjustable clamping platform enable the positioning device to adapt to pile foundations of different sizes. The hydraulic bidirectional cylinder allows the drag platform to adjust the clamping and positioning height according to the size of the pile foundation, while controlling the insertion rod to extend into the soil. In conjunction with the chassis, it increases the contact area with the ground to prevent sinking and increases the stability of the device. The rollers used to clamp the pile foundation have rubber material and concave and convex surfaces to increase the clamping stability of the positioning device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable building pile foundation positioning device, including a clamping platform, wherein two clamping platforms are provided symmetrically, and clamping components are movably connected to the inner side of each clamping platform. A lifting drag platform is movably connected to the lower end of the clamping platform. The bottom of the two drag platforms is provided with an adjustable U-shaped base composed of two symmetrical L-shaped rims and extension members. Multiple sets of hydraulic bidirectional cylinders are provided inside the U-shaped base. The lower end of the hydraulic bidirectional cylinder has a connecting rod through a piston rod, and the upper end is connected to the drag platform through the U-shaped base through the piston rod. A chassis is provided at the bottom of the U-shaped base.

[0006] Preferably, the clamping platform has multiple grooves on its inner side, and the clamping assembly includes multiple rockers and a stake assembly rotatably connected to the front end of the rockers.

[0007] Preferably, the pile-supporting assembly includes a movable seat and a roller, and the roller and the movable seat are movably connected.

[0008] Preferably, the roller surface is provided with an uneven rubber layer.

[0009] Preferably, the upper surface of the drag table is provided with a sliding groove for the lateral offset of the clamping table, and a second lead screw is provided in the sliding groove. The second lead screw is internally threaded to a sliding rod, and the upper end of the sliding rod is fixed to the bottom of the clamping table through the sliding groove.

[0010] Preferably, one end of the extension member is fixed to one of the L-shaped surrounds, and the other end is movably connected to another L-shaped surround. A lead screw is provided inside the other L-shaped surround, and the lead screw is movably connected to the extension member.

[0011] Preferably, the hydraulic bidirectional cylinder is connected to an external control valve.

[0012] Preferably, the hydraulic bidirectional cylinder adjusts the extension and retraction of the insert rod and the height of the drag platform via a control valve.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The U-shaped base of this utility model can be longitudinally adjusted according to the actual diameter of the pile foundation, and the positioning device can be adapted to pile foundations of different sizes by means of a clamping platform that can be adjusted laterally. The opening of the U-shaped base also makes it easy to move the positioning device to the outside of the pile foundation, so that the device is unrestricted and the original surrounding structure is simplified. It is not only more convenient to adjust, but also easier to operate.

[0015] 2. The clamping and positioning height and stability of this utility model are improved by adding a hydraulic bidirectional cylinder, which allows the height of the clamping platform to be controlled separately. This makes the positioning device more accurate when clamping the pile foundation, achieving the best positioning effect. The bottom insertion rod can extend a part of the structure and be fixed below the ground surface. This method increases the movement resistance of the positioning device under external influences, thereby avoiding positional deviation and affecting the positioning effect. In addition, the addition of a base plate at the bottom increases the contact surface with the ground, making the entire positioning structure less prone to tilting.

[0016] 3. The clamping stability of this utility model is achieved by tilting the rocker arm forward according to the diameter of the pile foundation, allowing the pile-holding component to fit against the surface. The movable connection between the pile-holding component and the rocker arm allows the rollers of the pile-holding component to adjust the angle of contact with the pile foundation surface according to the actual situation. This allows the rollers to rotate to a certain angle with the rocker arm during clamping, thereby increasing the gripping force of the multiple rollers. At the same time, the addition of a rubber textured surface increases the friction between the rollers and the pile foundation, preventing the pile from coming off during positioning.

[0023] 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.

[0024] To address the technical issues of low positioning accuracy caused by the instability of existing pile foundation positioning devices due to uneven ground at construction sites, and the inability to adjust them according to actual construction needs and pile height during pile positioning, please refer to [link to relevant documentation]. Figures 1-4 The following technical solutions are provided:

[0025] This utility model discloses an adjustable building pile foundation positioning device, comprising a clamping platform 3, with two symmetrical clamping platforms 3, each with a clamping component movably connected to its inner side. A lifting drag platform 2 is movably connected to the lower end of each clamping platform 3. The bottom of each drag platform 2 is provided with an adjustable U-shaped base 1 composed of two symmetrical L-shaped rims and extension members. The bottom of the U-shaped base 1 has a base plate 11, which increases the contact area with the ground, preventing the entire structure from tilting due to uneven force distribution and instability, thus ensuring proper positioning of the clamping components. The bottom of the U-shaped base 1 has a liftable insert rod 12 that penetrates the base plate 11. This design allows the bottom and middle structures of the positioning device to be adjusted according to the pile foundation, increasing the flexibility of the positioning device. The U-shaped base makes it easier to move the positioning device to the periphery of the pile foundation, simplifying the original perimeter structure. Furthermore, the U-shaped base 1 can be adjusted according to the actual diameter of the pile foundation, making adjustment more convenient and operation simpler.

[0026] The clamping platform 3 has multiple grooves on its inner side, providing space for the rocker arm 4 to tilt and swing forward. The clamping assembly includes multiple rocker arms 4 and a pile-stop assembly rotatably connected to the front end of the rocker arm 4. The pile-stop assembly can adjust the angle between itself and the rocker arm 4 according to the angle required for positioning the pile foundation, thereby improving the stability of the clamping. The pile-stop assembly includes a movable seat and a roller 5, and the roller 5 and the movable seat are movably connected. The surface of the roller 5 is provided with a concave-convex rubber layer to increase the friction between the roller 5 and the pile foundation, thereby improving the stability of the clamping and preventing the structure from shifting due to external influences.

[0027] The upper surface of the drag platform 2 is provided with a sliding groove for the lateral offset of the clamping platform 3. A second lead screw 21 is provided in the sliding groove, and a slide rod 31 is internally threaded to the lead screw 21. The upper end of the slide rod 31 is fixed to the bottom of the clamping platform 3 through the sliding groove. The left and right offset of the clamping platform 3 is controlled by the lead screw 21, so that it can be adjusted according to the diameter of the pile foundation, increasing the flexibility of the structure. One end of the extension is fixed to one of the L-shaped surrounds, and the other end is movably connected to the other L-shaped surround. A first lead screw 13 is provided in the other L-shaped surround, and the first lead screw 13 is movably connected to the extension. The first lead screw 13 is sleeved between the two L-shaped surrounds, and the extension is used to stabilize the extension structure. The extension method using the first lead screw 13 is more stable than some extension structures that are stretched.

[0028] The U-shaped base 1 contains multiple sets of hydraulic bidirectional cylinders 6. Each hydraulic bidirectional cylinder 6 has an extension rod at its upper end, and the upper end of the extension rod is fixed to the bottom of the platform 2 through the U-shaped base 1. The lower end of the hydraulic bidirectional cylinder 6 is movably connected to the insertion rod 12. The hydraulic bidirectional cylinder 6 is connected to an external control valve. The hydraulic bidirectional cylinder 6 can control the height of the clamping platform 3 and the outward extension length of the insertion rod 12 respectively, so that the positioning device can clamp the pile foundation at a more accurate height and achieve the best positioning effect. At the same time, a part of the structure extending from the insertion rod 12 can be fixed below the ground surface. The density of the soil below the ground surface is used to increase the offset resistance of the device when affected by external factors, so as to avoid the positioning shift during construction.

[0029] Working Principle: When positioning the pile foundation, first adjust the distance between the two L-shaped edges of the U-shaped base 1 according to the diameter of the pile foundation. When the distance is sufficient to surround the pile foundation, align the opening of the U-shaped base 1 with the pile foundation and push it to both sides of the pile foundation. Since the inner size of the U-shaped base 1 has changed, the position and height of the clamping components on the clamping platform 3 need to be adjusted accordingly. First, adjust the position of the clamping components by using the screw 21 in the drag platform 2, so that the two sets of clamping components can be located on both sides of the pile foundation. Then, control the height of the drag platform 2 by the hydraulic double-acting cylinder 6 to make the positioning height of the clamping components meet the current requirements of the pile foundation. Next, adjust each rocker arm 4 to tilt forward and approach the pile foundation so that the pile-supporting component can be attached to the surface of the pile foundation. Then, adjust the angle between the pile-supporting component and the rocker arm 4 so that the roller 5 of the pile-supporting component can... Figure 4 As shown, the rods abut against the outer surface of the pile foundation to increase positioning stability. Finally, the hydraulic bidirectional cylinder 6 controls the insertion rods 12 to extend downwards below the ground surface at their current fixed positions, increasing the stability of the entire structure. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
