Description

Technical Field

[0001] The invention relates to a building pile foundation anti-deviation device, belonging to the technical field of building construction. Background Art

[0002] In the field of construction engineering, pile foundation is a common form of deep foundation, consisting of a pile body and a cap connected to the top, or a single column directly connected to the pile. This type of structure is usually buried in the soil, and the bottom of the cap is in close contact with the stratum, thus providing stable support and necessary reinforcement for the building. However, in the actual construction process, pile foundation deviation is a frequently encountered technical problem, which not only affects the quality of the project, but also brings potential risks to subsequent construction. In order to overcome this challenge, the industry generally uses anti-deviation devices as auxiliary tools to effectively prevent the occurrence of such problems; Most of the widely used anti-deviation devices are based on the straight-tube design principle. The specific operation process is as follows: first, accurately excavate the foundation pit of the required size according to the design plan; then place the straight-tube device inside the foundation pit and ensure that its outer wall is close to the side wall of the foundation pit; finally, guide the prefabricated pile along the straight tube to slowly sink to the predetermined position, so as to achieve accurate positioning of the pile body during the lowering process, significantly reducing the possibility of various adverse consequences caused by deviation from the target; Although the above method can theoretically solve the problem of inaccurate pile positioning, it still has some shortcomings in practical application. Especially when the prefabricated piles are installed by hoisting, due to the influence of external factors (such as wind, mechanical vibration, etc.), unnecessary shaking or even dislocation often occurs near the entrance of the straight tube, increasing the risk of collision between the two, which may cause damage to the straight tube structure and even the entire foundation pit. In addition, a lot of manpower is required for fine adjustment, which not only prolongs the construction period, but also increases the labor intensity of the staff and affects the construction effect of the pile foundation.

[0020] When in use, first use the universal wheel 301 to move the multiple independent structures formed by the function box 3 and other components to the excavated foundation pit position, and arrange the multiple independent structures in a circular structure at the edge of the foundation pit. At this time, the multiple third connecting plates 14 are respectively located at the lower side of the multiple movable plates 17 at adjacent positions, and then the adjusting screw 151 is rotated. Since the adjusting screw 151 is threadedly connected with the threaded hole 161, the adjusting screw 151 rotates to simultaneously move the movable plate 16 downward, thereby moving the multiple movable plates 17 downward, thereby moving the multiple limiting rods 171 downward, and then the multiple limiting rods 171 respectively penetrate the corresponding multiple through holes 141, thereby limiting the installation between the multiple movable plates 17 and the multiple third connecting plates 14, thereby connecting the adjacent two main rods 1. In the same way as the above steps, the multiple main rods 1 are connected in pairs, thereby connecting the multiple main rods 1 and the multiple round rods 13 and other components to form the guide structure; Then, the bidirectional screw 34 is rotated. Since the bidirectional screw 34 is threadedly connected with the plurality of first sliders 32 and the plurality of second sliders 37, the rotation of the bidirectional screw 34 simultaneously causes the first slider 32 and the second slider 37 to move relative to and toward the middle position of the bidirectional screw 34, thereby causing the upper portion of the second support arm 33 and the upper portion of the third support arm 36 to move relative to and toward the middle position of the bidirectional screw 34, thereby causing the lower portion of the second support arm 33 and the lower portion of the third support arm 36 to move downward synchronously, thereby causing the lower pressure plate 35 to move downward, thereby causing the plurality of insertion rods 38 to move downward and be inserted into the ground, thereby achieving stable installation of the guide structure formed by the plurality of main rods 1 and the plurality of round rods 13 and other components, effectively reducing the probability of displacement of the placed pile foundation due to extrusion, and effectively ensuring the construction effect of the pile foundation; Then, multiple servo motors 501 are started, thereby causing multiple screw rods 5 to rotate synchronously. Since the screw rods 5 are connected to the nut seat 6 through a ball nut pair, the rotation of the screw rods 5 causes the nut seat 6 to move outward along the function box 3, thereby causing the lower parts of the multiple first support arms 7 to move outward synchronously, thereby causing the upper parts of the multiple first support arms 7 to move downward synchronously, thereby causing the multiple main rods 1 to move downward synchronously along the multiple connecting tubes 2, respectively, thereby causing the guide structure to move downward along the inner wall of the foundation pit to the extreme position, thereby achieving guidance and anti-deviation of the prefabricated pile foundation and protection of the inner wall of the foundation pit, effectively reducing the probability of deviation of the falling prefabricated pile foundation due to factors such as hoisting, effectively reducing the probability of collapse of the foundation pit due to factors such as hoisting, and effectively ensuring the construction effect of the pile foundation; Then, the plurality of electric push rods 81 are started to drive the plurality of rectangular frames 8 to swing outward to a suitable angle, so that the plurality of rectangular frames 8 form a tapered structure with a narrow bottom and a wide top, and then the prefabricated pile foundation is hoisted, and the lower part of the prefabricated pile foundation is inserted into the tapered structure, and then the plurality of electric push rods 81 are used to swing the plurality of rectangular frames 8 inward and return to the original position, so that the plurality of rollers 82 contact the outer end surface of the prefabricated pile foundation, thereby clamping and guiding the prefabricated pile foundation, effectively reducing the probability of collision between the falling prefabricated pile foundation and the main rod 1 and the round rod 13 due to hoisting and other factors, and effectively reducing the probability of damage to the foundation pit and the main rod 1 and other components, effectively reducing the time and labor intensity of the prefabricated pile foundation construction, and effectively ensuring the construction effect of the pile foundation; Then, the hoisted prefabricated pile foundation is guided into the guide structure formed by multiple main rods 1 and multiple round rods 13 and other components with the assistance of multiple rollers 82, so that the prefabricated pile foundation is placed in a suitable position in the foundation pit, thereby completing the construction of the prefabricated pile foundation, and then using multiple servo motors 501, multiple screw rods 5, multiple nut seats 6 and multiple first support arms 7, so that the guide structure formed by multiple main rods 1 and multiple round rods 13 and other components is moved out of the foundation pit, and then using the adjusting screw 151, threaded hole 161, movable plate 16, movable plate 17, limit rod 171 and through hole 141, the connection between two adjacent main rods 1 is released, and then the universal wheel 301 is used to move the function box 3 and other components to the next foundation pit position, so as to realize convenient disassembly and assembly between multiple main rods 1, facilitate use, effectively reduce the probability of damage to the inner wall of the foundation pit due to hoisting, and effectively ensure the construction effect of the subsequent pile foundation.

[0021] Embodiment 2: multiple servo motors 501, multiple screw rods 5, multiple nut seats 6 and multiple first arms 7 are used to enable the guide structure formed by multiple main rods 1 and multiple round rods 13 and other components to enter the foundation pit, and then the guide structure is used to guide and prevent the applied prefabricated pile foundation and protect the inner wall of the foundation pit, and multiple electric push rods 81, multiple rectangular frames 8 and multiple rollers 82 are used to clamp and guide the prefabricated pile foundation. However, in the process of moving the main rod 1 downward by the first arm 7, it is easy to cause outward pulling at the connection position between the first arm 7 and the main rod 1, and the main rod 1 and the connecting tube 2 are in a sliding connection, resulting in a seesaw structure in the upper and lower positions of the main rod 1, resulting in a tendency for the lower part of the main rod 1 to move inward due to the pulling factor, and a high probability of jamming at the sliding connection position between the main rod 1 and the connecting tube 2, resulting in a high probability of the main rod 1 being tilted and deformed, resulting in the guide structure formed by multiple main rods 1 and multiple round rods 13 and other components being unable to enter the foundation pit normally.

[0022] In order to solve the above problems, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Fig. 9 As shown, the U-shaped frame 25 whose vertical portion facing inward is slidably connected to the outer end of the main rod 1 and is located on the outer side of the moving plate 16 is arranged on the inner side of the mounting plate 31, and the U-shaped frame 25 is used to provide a mounting carrier for the third guide wheel 26 and other components, and the third guide wheel 26 whose other end is rotatably connected to the function box 3 is rotatably connected to the inner side of the horizontal portion of the U-shaped frame 25, and the rope 23 is guided by the third guide wheel 26, and then the second guide wheel 24 located on the inner side of the third guide wheel 26 and whose other end is rotatably connected to the function box 3 is rotatably connected to the inner side of the horizontal portion of the U-shaped frame 25, and the rope 23 is limited by the second guide wheel 24; The rope 23 located outside the second guide wheel 24 is wound around the outer end of the third guide wheel 26, and the sliding connection position between the main rod 1 and the connecting tube 2 is limited through the rope 23, and the first column 18 located inside the second guide wheel 24 and connected to the lower outer end of the main rod 1 and located on the upper side of the U-shaped frame 25 is connected to one end of the rope 23, and one end of the rope 23 is connected to the lower outer end of the main rod 1 through the first column 18, and then the second column 19 located directly above the first column 18 and connected to the upper outer end of the main rod 1 is connected to the other end of the rope 23, and the other end of the rope 23 is connected to the upper outer end of the main rod 1 through the second column 19; Multiple mounting seats 21 are respectively set on the upper ends of multiple connecting tubes 2, and a mounting carrier is provided for the first guide wheel 22 through the mounting seats 21. Two first guide wheels 22 located between the second guide wheel 24 and the third guide wheel 26 and having ropes 23 wrapped around the lower left outer ends are respectively rotatably connected to the opposite ends of the mounting seats 21, and the pulling force generated by the rope 23 is reversed through the first guide wheel 22.

[0023] When in use, firstly, a plurality of servo motors 501, a plurality of screw rods 5 and a plurality of nut seats 6 are used to move the lower parts of the plurality of first arms 7 outwardly, and at the same time, the upper parts of the plurality of first arms 7 are synchronously moved downwardly, thereby causing the plurality of main rods 1 to move downwardly along the plurality of connecting tubes 2 respectively. In the process of using the first arms 7 to drive the main rod 1 downwardly, an outward pulling force is generated at the connection position between the first arms 7 and the main rod 1, thereby applying an outward pulling force to the upper part of the main rod 1, and causing the second column 19 to have an outward moving tendency, thereby applying an outward pulling force to the end of the rope 23 connected to the second column 19; At this time, the corresponding first guide wheel 22 and the third guide wheel 26 will reverse the pulling force generated by the rope 23, so that the rope 23 applies an outward pulling force to the first column 18, so as to achieve synchronous pulling of the upper and lower parts of the main rod 1, effectively reducing the probability of the sliding connection between the main rod 1 and the connecting tube 2 being stuck, and effectively reducing the probability of the main rod 1 being tilted and deformed, effectively ensuring that the guide structure formed by multiple main rods 1 and multiple round rods 13 and other components can enter the foundation pit normally, and effectively ensuring the construction effect of the subsequent pile foundation; During the downward movement of the main rod 1, the first column 18 will pass through the corresponding U-shaped frame 25 and move downward, and the rope 23 will contact the upper outer end of the second guide wheel 24. With the assistance of the second guide wheel 24, the rope 23 will enter the foundation pit in a vertical state, thereby restricting the rope 23 entering the foundation pit, effectively avoiding relative movement between the rope 23 and the edge of the foundation pit opening, effectively reducing the probability of collapse at the foundation pit opening, and effectively ensuring the construction effect of the subsequent pile foundation.

[0024] Embodiment 3: A bidirectional screw 34, a first slider 32, a second slider 37, a second support arm 33, a third support arm 36, a lower pressure plate 35 and an insertion rod 38 are used to fasten and place the function box 3 and other components, and then a plurality of servo motors 501, a plurality of screw rods 5, a plurality of nut seats 6 and a plurality of first support arms 7 are used to make the guide structure formed by the plurality of main rods 1 and the plurality of round rods 13 and other components enter the foundation pit, and then the guide structure is used to guide and prevent the applied prefabricated pile foundation from deflection and protect the inner wall of the foundation pit, and a plurality of electric push rods are used. The rod 81, multiple rectangular frames 8 and multiple rollers 82 clamp and guide the prefabricated pile foundation, but the bidirectional screw 34 is generally rotated manually, which is labor-intensive and requires a long working time. During the insertion of the insertion rod 38 into the ground, the hardness of the ground soil is high, which may cause the insertion rod 38 to be lifted up, resulting in a high probability that the function box 3 and other components will tilt, resulting in a high probability that the guide structure formed by the multiple main rods 1 and multiple round rods 13 and other components that moves downward will cause damage to the inner wall of the foundation pit.

[0025] In order to solve the above problems, Figure 10-12As shown, the two bidirectional screw rods 34 are passed through the load-bearing block 4 at their outer ends and are respectively connected to two third gears 44 located on the outer side of the load-bearing block 4 and meshed at the top of the inner part of the synchronous belt 41. The bidirectional screw rods 34 are rotated through the third gears 44, and the second gear 43, which is rotatably connected to the outer side of the load-bearing block 4 and arranged in a triangular structure with the two third gears 44, is meshed with the inner bottom end of the synchronous belt 41 located on the outer side of the load-bearing block 4. The synchronous belt 41 is moved through the second gear 43, and then the first gear 42 located between the two third gears 44 and located in the synchronous belt 41 is meshed on the upper end of the second gear 43, and the second gear 43 is rotated through the first gear 42; The outer end surface of the load-bearing block 4 is recessed inward to form a groove 52 located at the inner end of the first gear 42. The groove 52 is used to provide a mounting space for the first annular plate 53 and other components. The outer end surface of the lead screw 5 that passes through the function box 3 at the outer end and is rotatably connected to the load-bearing block 4 and is located at the inner end of the groove 52 is recessed inward to form a rectangular hole 51. The rectangular hole 51 is used to provide a mounting space for the rectangular column 45. The rectangular column 45 that extends into the rectangular hole 51 at the inner end and is located in the groove 52 is installed at the middle position of the inner end of the first gear 42. The lead screw 5 is connected to the first gear 42 through the rectangular column 45. The first annular plate 53 located outside the rectangular column 45 is installed on the inner wall of the groove 52. The first annular plate 53 is used to provide a mounting carrier for the telescopic rod 54 and other components. A plurality of telescopic rods 54 located outside the rectangular column 45 are equidistantly arranged on the inner end of the first annular plate 53. The plurality of telescopic rods 54 are used in combination to guide the linear motion of the second annular plate 56. Then, a plurality of elastic members 55 located outside the plurality of telescopic rods 54 are equidistantly installed on the inner end of the first annular plate 53. The plurality of elastic members 55 are used in combination to return the second annular plate 56 to its original position. The elastic members 55 can be springs. The second annular plate 56 which is slidably connected in the groove 52 and connected to the other end of the multiple elastic members 55 and the other end of the multiple telescopic rods 54 is rotatably connected to the outer end of the rectangular column 45. The second annular plate 56 provides a mounting carrier for the annular magnetic plate 57 and other components, and the annular magnetic plate 57 located on the outside of the rectangular column 45 is arranged on the inner end of the second annular plate 56. Then, the annular electromagnet 58 which is located on the inner side of the annular magnetic plate 57 and on the outside of the rectangular column 45 and is mutually adsorbed with the annular magnetic plate 57 is arranged on the inner wall of the groove 52. The annular magnetic plate 57 and the annular electromagnet 58 are used in conjunction with each other to move the second annular plate 56 inward.

[0026] When in use, the multi-functional boxes 3 and other components are first moved to the excavated foundation pit position by using the universal wheels 301, and the multi-functional boxes 3 and other components are arranged in a circular structure at the edge of the foundation pit. The multi-functional boxes 3 and other components are then connected in pairs by using the adjusting screws 151, the threaded holes 161, the third connecting plate 14, the movable plate 17, the limiting rods 171 and the through holes 141, so as to form a guide structure formed by the multi-functional boxes 3 and other components; Then, the circuit of the annular electromagnet 58 is turned on. Since the annular electromagnet 58 and the annular magnetic plate 57 are arranged to be attracted to each other, an adsorption force is generated between the annular electromagnet 58 and the annular magnetic plate 57. Under the action of the adsorption force, the second annular plate 56 and the rectangular column 45 move inward, and then the rectangular column 45 is inserted into the rectangular hole 51. At the same time, the first gear 42 and the second gear 43 are meshed with each other, and the multiple elastic members 55 are stretched, so that the elastic members 55 generate elastic force. Then, the guide structure is moved downward by using multiple servo motors 501, multiple screw rods 5 and multiple nut seats 6. At this time, the screw rod 5 is in a rotating state, and with the assistance of the rectangular column 45 and the rectangular hole 51, the first gear 42 is rotated, and then the second gear 43 is rotated, and with the assistance of the synchronous belt 41, the two third gears 44 are rotated synchronously, so that the two bidirectional screw rods 34 are rotated synchronously, and with the assistance of the first slider 32, the second slider 37, the second support arm 33, the third support arm 36 and the lower pressure plate 35, the multiple insertion rods 38 are synchronously inserted into the ground; After the insertion rod 38 is inserted into the ground, the circuit of the annular electromagnet 58 is disconnected, and under the elastic force of the multiple elastic members 55, the second annular plate 56 and the rectangular column 45 are moved outward to their original positions, thereby separating the rectangular column 45 from the rectangular hole 51, thereby releasing the connection between the first gear 42 and the screw rod 5, allowing the guide structure to continue to enter the foundation pit, realizing the mechanical insertion and removal of the insertion rod 38, effectively reducing labor intensity and working time, effectively reducing the probability of tilting of components such as the function box 3, and effectively reducing the probability of damage to the inner wall of the foundation pit caused by the guide structure formed by components such as multiple main rods 1 and multiple round rods 13, effectively ensuring the construction effect of the subsequent pile foundation.
