Technical Field
[0001] The utility model relates to the technical field of pile foundation hole forming, in particular to a building pile foundation hole forming detection device. Background Art
[0002] The purpose of drilling the pile foundation is to ensure the accuracy of the pile foundation hole so that it can match the height of the steel cage. Therefore, it is necessary to use a detection device to detect it after drilling.
[0003] However, the traditional medium-hole depth detection adopts manual rope grabbing and releasing detection. Due to manual negligence, the rope may not be grasped tightly, causing it to fall in together with the counterweight, affecting subsequent work, and it is impossible to control the rope to always be perpendicular to the hole. Therefore, a building pile foundation hole detection device is needed to solve the above technical problems. Utility Model Content
[0004] The main purpose of the utility model is to provide a building pile foundation hole detection device, which can effectively solve the technical problems in the background technology.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A building pile foundation hole detection device includes a top plate, a first fixing hole is formed on the top plate, a T-shaped block is fixed to the bottom surface of the top plate through the first fixing hole, a second fixing hole is formed on the T-shaped block and corresponds to the first fixing hole one by one, a receiving groove is formed on the T-shaped block, a threaded hole is formed on the top surface of the receiving groove, a plurality of balls are fixed to the inner wall of the receiving groove, and a threaded rod is threadedly connected and a placement block is inserted at the positions corresponding to the threaded hole and the receiving groove.
[0007] As a further solution of the present invention, an elastic ball is fixed on the inner top wall of the threaded hole.
[0008] As a further solution of the present invention, a first support column is fixed to the bottom surface of the placement block, a first threaded section is provided on the outer wall of the first support column, and a plurality of limit strips arranged at equal angles are fixed to the inner wall of the first support column.
[0009] As a further solution of the present invention, a second support column is inserted into the first support column, a limiting groove corresponding to the limiting strip is provided on the second support column, and a second threaded segment connected to the first threaded segment is provided on the outer wall of the second support column.
[0010] As a further solution of the present invention, a fixing ring is movably connected to the outer wall of the first support column, and the inner wall of the fixing ring is engraved with internal threads corresponding to the first thread segment and the second thread segment.
[0011] As a further solution of the present invention, symmetrical blocks are fixed on the bottom surface of the top plate, and a winding roller is rotatably connected between the symmetrical blocks. A suspension rope is wound around the winding roller, and a counterweight block is fixed at the end of the suspension rope. A position sensor connected to the signal of the external device is fixed on the bottom surface of the counterweight block.
[0012] As a further solution of the present invention, a vertical plate is fixed on the bottom wall of the top plate, and the vertical plate is provided with a through hole for the suspension rope to pass through.
[0013] The beneficial effects of the utility model are as follows:
[0014] 1. Fix the top plate and the T-shaped block through the first fixing hole and the second fixing hole. When the threaded rod is screwed into the threaded hole, the placement block enters the accommodating groove. Then insert the second support column into the first support column and the limit bar into the limit groove until the first thread segment and the second thread segment are connected. Move the fixing ring and screw it until it completely covers the first thread segment and the second thread segment. This completes the assembly of the entire device and facilitates subsequent disassembly and carrying.
[0015] 2. The winding roller winds the lifting rope. When the counterweight is lowered into the pile foundation hole, the lifting rope passes through the perforations on the vertical plate to limit its fall in the vertical position of the pile foundation hole. This prevents the lifting rope from bending and falling, which may lead to inaccurate measurement results. When the rope reaches the bottom under the induction of the position sensor, the rope is stopped from being released. This prevents the rope from being released again after it has fallen into the bottom, which may lead to inaccurate measurement results. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0021] like Figure 1-3 As shown, a building pile foundation hole detection device includes a top plate 1, a first fixing hole 2 is opened on the top plate 1, a T-shaped block 3 is fixed to the bottom surface of the top plate 1 through the first fixing hole 2, a second fixing hole 4 corresponding to the first fixing hole 2 is opened on the T-shaped block 3, a receiving groove 5 is opened on the T-shaped block 3, a threaded hole 6 is opened on the top surface of the receiving groove 5, a plurality of balls 7 are fixed to the inner wall of the receiving groove 5, and threaded rods 8 are threadedly connected and placement blocks 9 are inserted at the positions corresponding to the threaded holes 6 and the receiving grooves 5 respectively. The balls 7 can remain stable even under force or vibration and will not shift or loosen.
[0022] In this embodiment, an elastic ball 10 is fixed on the inner top wall of the threaded hole 6. The elastic ball 10 can deform when the threaded rod 8 is screwed in to generate elastic thrust on the threaded rod 8, thereby reducing the gap between the threads and increasing the stability of the fixation.
[0023] In this embodiment, a first support column 11 is fixed to the bottom surface of the placement block 9, a first threaded section 12 is provided on the outer wall of the first support column 11, a plurality of limit strips 13 arranged at equal angles are fixed to the inner wall of the first support column 11, a second support column 14 is inserted into the first support column 11, a limit groove 15 corresponding to the limit strip 13 is provided on the second support column 14, and a second threaded section 16 connected to the first threaded section 12 is provided on the outer wall of the second support column 14. After the limit strip 13 is inserted into the limit groove 15, the rotation of the first support column 11 and the second support column 14 can be restricted to avoid loosening of the fixing ring 17.
[0024] In this embodiment, a fixing ring 17 is movably connected to the outer wall of the first support column 11, and the inner wall of the fixing ring 17 is engraved with an internal thread corresponding to the first thread segment 12 and the second thread segment 16. The fixing ring 17 is moved and screwed to connect the first thread segment 12 and the second thread segment 16 to prevent the first support column 11 or the second support column 14 from moving and causing the fixation to loosen.
[0025] In this embodiment, symmetrical blocks 18 are fixed to the bottom surface of the top plate 1, and winding rollers 19 are rotatably connected between the symmetrical blocks 18. A lifting rope 20 is wound around the winding roller 19, and a counterweight block 21 is fixed to the end of the lifting rope 20. A position sensor 22 connected to the signal of the external device is fixed to the bottom surface of the counterweight block 21. The position sensor 22 can send a signal when it reaches the bottom surface of the pile foundation hole to avoid inaccurate measurement results caused by continuous line release.
[0026] In this embodiment, a vertical plate 23 is fixed on the bottom wall of the top plate 1. The vertical plate 23 is provided with a through-hole for the suspension rope 20 to pass through. The position of the through-hole always corresponds to the position of the pile foundation hole, thereby preventing the suspension rope 20 from bending and entering, resulting in inaccurate subsequent measurement results.
[0027] It should be noted that the present invention is a device for detecting the formation of a hole in a pile foundation of a building. When in use, the top plate 1 and the T-shaped block 3 are fixed through the first fixing hole 2 and the second fixing hole 4. When the threaded rod 8 is screwed into the threaded hole 6, the placement block 9 enters the receiving groove 5, and then the second support column 14 is inserted into the first support column 11, and the limiting strip 13 is inserted into the limiting groove 15. When the first thread segment 12 is connected to the second thread segment 16, the fixing ring 17 is moved and screwed to completely cover the first thread segment 12 and the second thread segment 16. The two threaded sections 16 can realize the splicing of the entire device and are convenient for subsequent disassembly and carrying. The winding roller 19 winds the lifting rope 20. When the counterweight block 21 is lowered into the pile foundation hole, the lifting rope 20 passes through the perforation restriction on the vertical plate 23, so that the lifting rope 20 always falls in the vertical position of the pile foundation hole, which can avoid the lifting rope 20 bending and falling, resulting in inaccurate measurement results. When the rope reaches the bottom surface under the induction of the position sensor 22, the rope is stopped from being released, so as to avoid the lifting rope 20 falling into the bottom surface and causing inaccurate measurement results.
[0028] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
