Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation anti-deviation, in particular to a building pile foundation anti-deviation device. Background Art

[0002] The building pile foundation consists of a foundation pile and a cap connected to the top of the pile. If the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low cap pile foundation; if the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground, it is called a high cap pile foundation. The building pile foundation is usually a low cap pile foundation. It is widely used in high-rise buildings, bridges, high-speed railways and other projects. In order to prevent the building pile foundation from shifting during construction, it is usually necessary to use a special anti-shift device to limit the building pile foundation.

[0003] A Chinese utility model patent with the publication number CN216586635U discloses an anti-drift building pile foundation device, which achieves the purpose of limiting by installing a penetration end and a level meter. The lower half of the combined device is penetrated into the soil through the penetration end for fixation, and the level meter observes the level of the device during the penetration process so as to make timely adjustments to prevent drift. With respect to the above-mentioned related technologies, the inventor believes that there are the following defects:

[0004] When the device is actually used, the soil near the pile foundation has not been treated, making the soil relatively soft. Also, because the position where the device is fixed to the ground is difficult to adjust, the device is prone to loosening after being fixed to the soft soil, thereby affecting the device's anti-deviation effect on the pile foundation. For this reason, we provide a building pile foundation anti-deviation device. Utility Model Content

[0023] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0024] Embodiment 1:

[0025] Please combine Figure 1-3 , a building pile foundation anti-deviation device of this embodiment includes:

[0026] Two groups of rectangular frames 1, vertical rods 2 are symmetrically fixedly connected between the two groups of rectangular frames 1, bidirectional screw rods 3 are symmetrically rotatably connected between the two groups of rectangular frames 1, both sides of the bidirectional screw rods 3 are threadedly connected to movable plates 4, and the movable plates 4 are slidably connected to the vertical rods 2, and limit plates 5 are symmetrically arranged between the two groups of rectangular frames 1, and connecting rods 6 are hinged between the limit plates 5 and the movable plates 4 through hinges, and motors 7 are symmetrically fixedly connected to the top of the upper rectangular frame 1, and the rotor ends of the motors 7 are coaxially fixedly connected to the two groups of bidirectional screw rods 3, so as to drive the two groups of limit plates 5 to approach the pile foundation for limiting and preventing deviation, and the limit plates 5 are designed as arc-shaped structures, so as to better limit the pile foundation;

[0027] The adjusting and fixing assembly includes an active cavity 101 symmetrically opened on the lower rectangular frame 1, a strip plate 102 is movably connected inside the active cavity 101, and one end of the strip plate 102 extends to the outside of the active cavity 101, and one end of the strip plate 102 is fixedly connected to a fixed plate 103, a positioning hole penetrating the fixed plate 103 is opened on the fixed plate 103, and a positioning rod 104 is inserted inside the positioning hole, and a screw rod 105 is symmetrically rotatably connected to the lower rectangular frame 1, and the external thread of the screw rod 105 is connected to a threaded sleeve 106, and the threaded sleeve 106 is connected to the strip plate 102 on the same side. A connecting rod 2 107 is hinged through a hinge, and both sides of the strip plate 102 are fixedly connected to limit blocks 108. The inner wall of the movable cavity 101 is provided with a limit groove corresponding to the position of the limit block 108 and is slidably connected to the limit block 108, which can play a certain guiding role in the horizontal movement of the strip plate 102. The diameter of the positioning hole is consistent with the diameter of the positioning rod 104 to avoid a gap between the positioning rod 104 and the positioning hole, which will reduce the stability of the device when it is fixed. The top of the screw rod 105 is coaxially fixedly connected with an anti-slip handwheel 109 to facilitate the rotation of the screw rod 105.

[0028] The implementation principle of a construction pile foundation anti-deviation device in the embodiment of the present application is: by rotating the anti-skid handwheel 109 to drive the screw rod 105 to rotate, and utilizing the threaded cooperation between the threaded sleeve 106 and the screw rod 105, the hinged effect between the threaded sleeve 106 and the strip plate 102 and the connecting rod 107, the movable cooperation between the strip plate 102 and the movable cavity 101, and the sliding cooperation between the limit block 108 and the limit groove, the threaded sleeve 106 can be driven to move vertically downward to push the strip plate 102 to the outside of the movable cavity 101, so that the position of the fixed plate 103 can be adjusted. The range in which the device can be fixed is increased, so that the fixing plate 103 is conveniently moved to a relatively solid soil surface, and the positioning rod 104 is inserted into the positioning hole and penetrated into the ground, so that the device can be effectively and stably fixed, and the bidirectional screw rod 3 is driven to rotate by starting the motor 7, and the sliding cooperation between the movable plate 4 and the vertical rod 2 is utilized, so that the two groups of movable plates 4 can be driven to move toward each other, and under the cooperation of the hinged action between the movable plate 4 and the limit plate 5 and the connecting rod 6, the two groups of limit plates 5 can be pushed toward the center to limit the pile foundation, thereby preventing the pile foundation from shifting.
