Description

Technical Field

[0001] The invention relates to the field of anti-positioning and deviation mechanisms, in particular to an anti-positioning and deviation mechanism for installing a steel cage in a pile foundation engineering for building construction. Background Art

[0002] Through reasonable design and construction of pile foundations, the settlement of buildings can be controlled within the allowable range to ensure the normal use of the buildings. For some buildings with high settlement requirements, such as large shopping malls, hospitals, precision instrument factories, etc., pile foundations can effectively reduce settlement and avoid damage to the internal structure of the building or malfunction of equipment due to settlement differences.

[0003] Clear obstacles in the construction site, such as stones, garbage, etc., to ensure that the construction site is flat and solid, meet the walking and operation requirements of equipment such as pile drivers, measure and lay out lines, use total stations and other measuring instruments to accurately determine the pile position according to the design drawings, and mark the center of the pile position with wooden piles or steel bars, and set up control piles at the same time so that the pile position can be checked at any time during the construction process. The steel cage is mainly composed of main bars and coil bars during the construction process. The main bars are also called force bars. Those that bear tensile stress are usually called longitudinal tensile steel bars and tensile steel bars. Those that bear compressive stress are usually called longitudinal compressive steel bars and compressive bars, collectively referred to as force bars. Coil bars are usually determined by the diameter of the foundation pile. Through coil bars, the main bars are regularly welded together to form a steel cage, and then the steel cage is hoisted into the foundation pile hole by a crane. It should be lowered slowly during hoisting to avoid the steel cage colliding with the hole wall. When the steel cage is lowered to the designed position, it should be fixed in time to prevent the steel cage from shifting or floating. After the steel cage is hoisted into place, it should be positioned so that the center of the steel cage coincides with the center of the pile hole as much as possible.

[0004] For deep foundation pits, when placing steel cages, in order to better hoist them, the steel cages are usually divided into multiple sections of equal length, and then the two groups of steel cages are docked during the hoisting process by a crane. The existing docking method is to manually use multiple groups of support bars to simply support one group of steel cages, and then use a crane to hoist them for docking. With the continuous improvement of current engineering standards, the traditional docking method cannot meet the high-precision installation requirements. Therefore, in order to improve the installation accuracy of the steel cages and better facilitate manual operation, a mechanism for preventing misalignment is needed to assist the installation process of the steel cages. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide an anti-alignment and deviation mechanism for installing a steel cage in a pile foundation project for building construction, so as to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: An anti-offset mechanism for the installation of a steel cage in a pile foundation project for building construction includes an anti-offset mechanism main body and a steel cage. The anti-offset mechanism main body includes a housing, a limiting plate, and a support plate. The end of the limiting plate is fixedly installed with a support plate, and a positioning mechanism for guiding the anti-offset mechanism main body is installed in the limiting plate;

[0007] The positioning mechanism includes a first rotating shaft slidably installed in the limiting plate. The end of the first rotating shaft is fixedly installed with a transmission rod, and the other end of the transmission rod is fixedly installed with a second rotating shaft. The outer wall of the second rotating shaft is rotatably installed with a connecting rod, and the outer wall of the slider is slidably installed with the connecting rod. The end of the connecting rod is fixedly installed with a brake block. A first spring corresponding to the slider is slidably installed in the brake block. The end of the transmission rod is rotatably installed with a threaded sleeve, and the end of the threaded sleeve is fixedly installed with a guiding block. A constraint mechanism for further restricting the steel cage is installed on the outer wall of the threaded sleeve;

[0008] The constraint mechanism includes a limiting block fixedly installed on the outer wall of the threaded sleeve. A guiding rod is slidably installed in the limiting block, and a second spring is sleeved on the outer wall of the guiding rod. The end of the second spring is fixedly installed with a guiding plate;

[0009] A driving mechanism for moving the threaded sleeve is installed on the outer wall of the support plate.

[0010] By adopting the above technical solution, when the transmission rod rotates, the brake block is smoothly attached to the inner wall of the pile foundation pit, so that the anti-offset mechanism main body moves towards the center position of the pile foundation pit under the setting of multiple brake blocks. At the same time, through the sliding setting of the second spring and the guiding plate, during the hoisting process of the anti-offset mechanism main body, under the guidance of the guiding plate, the steel cage smoothly moves to the center position of the anti-offset mechanism main body. Due to the two position corrections, the position of the steel cage during the hoisting process is ensured to be accurate, and the offset of the steel cage position is avoided.

[0011] Furthermore, the cross-section of the first rotating shaft is designed in a circular structure, and two groups of the first rotating shafts are symmetrically arranged on the outer wall of the transmission rod.

[0012] By adopting the above technical solution, it is ensured that the movement of the transmission rod in the anti-offset mechanism main body is smoother.

[0013] Furthermore, the cross-section of the slider is designed in a rectangular structure, and two groups of the brake blocks are symmetrically arranged on the outer wall of the transmission rod.

[0014] By adopting the above technical solution, it is ensured that the movement of the brake block is smoother.

[0015] Furthermore, one end of the first spring is in contact with the outer wall of the slider, and the other end of the first spring is in contact with the inner wall of the connecting rod. The cross-section of the brake block is designed in an arc structure.

[0016] By adopting the above technical solutions, it is ensured that the slider can smoothly slide within the connecting rod when the transmission rod moves, and at the same time, when the brake block is in contact with the inner wall of the foundation pile pit, the change of the inner wall of the foundation pile pit is avoided.

[0017] Furthermore, one end of the second spring is in contact with the inner wall of the limiting block, and the other end of the second spring is in contact with the outer wall of the guiding rod, and the guiding plate is designed to be inclined.

[0018] By adopting the above technical solutions, it is ensured that under the restriction of the second spring and guided by the guiding plate, the steel reinforcement cage can smoothly move to the center of the anti-counterposition offset mechanism main body.

[0019] Furthermore, the driving mechanism includes a right-angle motor, a driving gear, a first driven gear, a second tooth, a second driven gear and a screw rod, and the driving gear is fixedly connected to the end of the right-angle motor, and a first driven gear corresponding to the driving gear is rotatably connected within the anti-counterposition offset mechanism main body.

[0020] By adopting the above technical solutions, it is ensured that the first driven gear can rotate better within the anti-counterposition offset mechanism main body.

[0021] Furthermore, the outer wall of the first driven gear is fixedly connected with a second tooth, a second driven gear corresponding to the second tooth is rotatably connected within the anti-counterposition offset mechanism main body, and the outer wall of the second driven gear is fixedly connected with a screw rod, and multiple groups of second teeth are arranged at equal angles on the outer wall of the first driven gear.

[0022] By adopting the above technical solutions, it is ensured that while the first driven gear rotates, it can always drive the second driven gear to rotate within the anti-counterposition offset mechanism main body.

[0023] Furthermore, the second driven gear is rotatably connected to the anti-counterposition offset mechanism main body, and multiple groups of the second driven gears are arranged at equal angles within the anti-counterposition offset mechanism main body, and the screw rod is threadedly connected to the threaded sleeve.

[0024] By adopting the above technical solutions, it is ensured that the screw rod can smoothly drive the threaded sleeve to slide within the anti-counterposition offset mechanism main body.

[0025] Furthermore, the cross-section of the threaded sleeve is designed in a rectangular structure, and the threaded sleeve is slidably connected to the anti-counterposition offset mechanism main body, and a chute corresponding to the threaded sleeve is provided within the anti-counterposition offset mechanism main body.

[0026] By adopting the above technical solutions, it is ensured that the movement of the threaded sleeve within the anti-counterposition offset mechanism main body is smoother.

[0027] Furthermore, the cross-section of the guiding block is designed in a triangular structure, and the side of the guiding block away from the second driven gear is designed in an arc structure.

[0028] By adopting the above technical solution, it is ensured that the threaded sleeve can smoothly support the spiral bars of the steel reinforcement cage.

[0029] In summary, the present invention mainly has the following beneficial effects:

[0030] 1. When the driving rod rotates in the present invention, the brake blocks are smoothly attached to the inner wall of the foundation pile pit. With the arrangement of multiple groups of brake blocks, the main body of the anti-position offset mechanism moves towards the center position of the foundation pile pit. At the same time, through the sliding arrangement of the second spring and the guiding plate, during the hoisting process of the steel reinforcement cage, under the guidance of the guiding plate, the steel reinforcement cage smoothly moves to the center position of the main body of the anti-position offset mechanism. After two position corrections, the accuracy of the position of the steel reinforcement cage during the hoisting process is ensured, and the offset of the position of the steel reinforcement cage is avoided.

[0031] 2. Through the support of the limiting block in the present invention, the first group of steel reinforcement cages can be kept stable within the main body of the anti-position offset mechanism after hoisting, so that the user can better dock the second group of steel reinforcement cages. Then, through the setting of the driving assembly, multiple groups of threaded sleeves can move simultaneously, and further drive multiple groups of driving rods to rotate simultaneously, further improving the mobility of the device.

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and cannot be understood as a limitation of the present invention.

[0042] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0043] An anti-alignment offset mechanism for installing a steel reinforcement cage in a pile foundation project for building construction, as Figure 1 - Figure 8 shown, includes a main body 1 of the anti-alignment offset mechanism and a steel reinforcement cage 2. The main body 1 of the anti-alignment offset mechanism includes a housing, a limiting plate 10, and a support plate 11. The end of the limiting plate 10 is fixedly installed with a support plate 11, and a positioning mechanism for guiding the main body 1 of the anti-alignment offset mechanism is installed in the limiting plate 10;

[0044] The positioning mechanism includes a first rotating shaft 71 slidably installed in the limiting plate 10. The end of the first rotating shaft 71 is fixedly installed with a transmission rod 7, and the other end of the transmission rod 7 is fixedly installed with a second rotating shaft 72. The outer wall of the second rotating shaft 72 is rotatably installed with a connecting rod 81. The outer wall of the slide block 82 is slidably installed with the connecting rod 81, and the end of the connecting rod 81 is fixedly installed with a brake block 8. A first spring 83 corresponding to the slide block 82 is slidably installed in the brake block 8. The end of the transmission rod 7 is rotatably installed with a threaded sleeve 6, and the end of the threaded sleeve 6 is fixedly installed with a guide block 61. A constraint mechanism for further restricting the steel reinforcement cage 2 is installed on the outer wall of the threaded sleeve 6;

[0045] The constraint mechanism includes a limiting block 9 fixedly installed on the outer wall of the threaded sleeve 6. A guide rod 91 is slidably installed in the limiting block 9, and a second spring 92 is sleeved on the outer wall of the guide rod 91. The end of the second spring 92 is fixedly installed with a guide plate 93;

[0046] A driving mechanism for moving the threaded sleeve 6 is installed on the outer wall of the support plate 11.

[0047] Please refer to Figure 7 - Figure 8 The cross-section of the first rotating shaft 71 is designed to be circular, and two groups of the first rotating shafts 71 are symmetrically arranged on the outer wall of the transmission rod 7, so that the first rotating shaft 71 can slide smoothly while sliding in the anti-counterposition offset mechanism main body 1, ensuring that the transmission rod 7 moves more smoothly in the anti-counterposition offset mechanism main body 1.

[0048] Please refer to Figure 7 - Figure 8 The cross-section of the slider 82 is designed to be rectangular, and two groups of the brake blocks 8 are symmetrically arranged on the outer wall of the transmission rod 7. When the second rotating shaft 72 rotates in the slider 82, it can smoothly drive the slider 82 to slide in the connecting rod 81, ensuring that the movement of the brake block 8 is smoother.

[0049] Please refer to Figure 4 - Figure 8 One end of the first spring 83 is in contact with the outer wall of the slider 82, and the other end of the first spring 83 is in contact with the inner wall of the connecting rod 81. Through the restriction of the first spring 83, when the anti-counterposition offset mechanism main body 1 is reset, under the action of the first spring 83, the slider 82 can always stay at the bottom of the connecting rod 81. The cross-section of the brake block 8 is designed to be arc-shaped. When the brake block 8 is in contact with the inner wall of the foundation pile pit, the arc design of the brake block 8 can reduce the shape of the inner wall of the foundation pile pit, ensuring that the slider 82 can slide smoothly in the connecting rod 81 when the transmission rod 7 moves. At the same time, when the brake block 8 is in contact with the inner wall of the foundation pile pit, it can avoid changing the inner wall of the foundation pile pit.

[0050] Please refer to Figure 4 and Figure 6 One end of the second spring 92 is in contact with the inner wall of the limiting block 9, and the other end of the second spring 92 is in contact with the outer wall of the guiding rod 91. The guiding plate 93 is inclined. When the guiding plate 93 is squeezed by the inner stirrups of the steel reinforcement cage 2, it starts to squeeze the second spring 92 through the guiding rod 91. At this time, due to the action of multiple groups of the second springs 92, the steel reinforcement cage 2 moves towards the center of the anti-counterposition offset mechanism main body 1, ensuring that under the restriction of the second spring 92 and through the guiding of the guiding plate 93, the steel reinforcement cage 2 moves smoothly to the center of the anti-counterposition offset mechanism main body 1.

[0051] Please refer to Figure 2 - Figure 5 The driving assembly includes a right-angle motor 3, a driving gear 31, a first driven gear 4, a second tooth 41, a second driven gear 5, and a screw rod 51. The driving gear 31 is fixedly connected to the end of the right-angle motor 3. A first driven gear 4 corresponding to the driving gear 31 is rotatably connected in the anti-counterposition offset mechanism main body 1. Under the braking of the driving assembly, by starting the right-angle motor 3, the driving gear 31 is driven to rotate. At this time, the first driven gear 4 starts to rotate, ensuring that the first driven gear 4 can rotate better in the anti-counterposition offset mechanism main body 1.

[0052] Please refer to Figure 2 - Figure 5 On the outer wall of the first driven gear 4, a second tooth 41 is fixedly connected. Inside the main body 1 of the anti-positioning deviation mechanism, a second driven gear 5 corresponding to the second tooth 41 is rotatably connected. On the outer wall of the second driven gear 5, a screw rod 51 is fixedly installed. A plurality of groups of second teeth 41 are arranged at equal angles on the outer wall of the first driven gear 4. The first driven gear 4 rotates to drive the second driven gear 5 to start rotating through the second tooth 41, ensuring that while the first driven gear 4 rotates, it can always drive the second driven gear 5 to rotate inside the main body 1 of the anti-positioning deviation mechanism.

[0053] Please refer to Figure 2 - Figure 5 The second driven gear 5 is rotatably connected to the main body 1 of the anti-positioning deviation mechanism, and a plurality of groups of the second driven gear 5 are arranged at equal angles inside the main body 1 of the anti-positioning deviation mechanism. The screw rod 51 is threadedly connected to the threaded sleeve 6. The second driven gear 5 rotates to drive the screw rod 51 to rotate simultaneously. At this time, the threaded sleeve 6 threadedly connected to the screw rod 51 starts to slide inside the main body 1 of the anti-positioning deviation mechanism, ensuring that the screw rod 51 can smoothly drive the threaded sleeve 6 to slide inside the main body 1 of the anti-positioning deviation mechanism.

[0054] Please refer to Figure 4 - Figure 8 The cross-section of the threaded sleeve 6 is designed in a rectangular structure to prevent the threaded sleeve 6 from rotating by itself under the action of the screw rod 51 inside the main body 1 of the anti-positioning deviation mechanism. The threaded sleeve 6 is slidably connected to the main body 1 of the anti-positioning deviation mechanism. Inside the main body 1 of the anti-positioning deviation mechanism, a chute corresponding to the threaded sleeve 6 is provided, ensuring that the movement of the threaded sleeve 6 inside the main body 1 of the anti-positioning deviation mechanism is smoother.

[0055] Please refer to Figure 6 - Figure 8 The cross-section of the guiding block 61 is designed in a triangular structure, and the side of the guiding block 61 away from the second driven gear 5 is designed in an arc structure. Through the setting of the guiding block 61, when the end of the guiding block 61 is in contact with the main reinforcement of the steel reinforcement cage 2, the steel reinforcement cage 2 can be smoothly guided to the side wall of the threaded sleeve 6, ensuring that the threaded sleeve 6 can smoothly support the spiral reinforcement of the steel reinforcement cage 2.

[0056] The working principle of the present invention is as follows: First, through the guidance of the brake block 8 and the transmission rod 7, the user places the main body 1 of the anti-positioning deviation mechanism in the foundation pile pit. At this time, the transmission rod 7 and the brake block 8 are located in the foundation pile pit. At this time, the user can start hoisting the first group of steel reinforcement cages 2. As the steel reinforcement cage 2 descends, when the spiral reinforcement at the end of the steel reinforcement cage 2 is higher than the upper part of the limiting block 9, the user can start the driving assembly;

[0057] First, start the right-angle motor 3, which then drives the driving gear 31 to start rotating. At this time, the first driven gear 4 corresponding to the right-angle motor 3 is simultaneously driven, and the first driven gear 4 starts to rotate within the anti-counterposition offset mechanism main body 1. At the same time, it drives the second tooth 41 to start moving within the anti-counterposition offset mechanism main body 1, and then drives the second driven gear 5 to start sliding within the anti-counterposition offset mechanism main body 1. As the second driven gear 5 rotates, it drives the screw rod 51 to rotate simultaneously. At this time, the threaded sleeve 6 threadedly connected to the screw rod 51 moves within the anti-counterposition offset mechanism main body 1 under the drive of the screw rod 51. As the threaded sleeve 6 moves, it drives the transmission rod 7 to start moving within the anti-counterposition offset mechanism main body 1. At this time, due to the restriction of the first rotating shaft 71, the transmission rod 7 rotates within the anti-counterposition offset mechanism main body 1 while moving within the anti-counterposition offset mechanism main body 1, and then drives the brake block 8 to start moving within the pile foundation pit. When the brake block 8 abuts against the inner wall of the pile foundation pit, under the restriction of the inner wall of the pile foundation pit, the outer wall of the brake block 8 gradually abuts against the inner wall of the pile foundation pit. At the same time, under the restriction of the second rotating shaft 72, the slider 82 starts to slide within the connecting rod 81, and the outer wall of the slider 82 starts to compress the first spring 83. As the transmission rod 7 continues to rotate, the brake block 8 and the inner wall of the pile foundation pit are driven by the second rotating shaft 72 to fit tightly. At this time, due to the restriction of the inner wall of the pile foundation pit, the brake block 8 starts to react on the transmission rod 7 through the second rotating shaft 72. Under the action of multiple brake blocks 8, the anti-counterposition offset mechanism main body 1 is driven to move towards the center of the pile foundation pit within the pile foundation pit through the threaded sleeve 6 and the screw rod 51, so that the anti-counterposition offset mechanism main body 1 and the pile foundation pit maintain a concentric position;

[0058] At the same time, as the threaded sleeve 6 moves, the guiding block 61 starts to move within the steel reinforcement cage 2. Due to the arc design at the end of the guiding block 61, the main reinforcement of the steel reinforcement cage 2 is smoothly guided to the side wall of the threaded sleeve 6. At this time, due to the setting of the guiding plate 93, under the restriction of the stirrup of the steel reinforcement cage 2, the guiding plate 93 starts to slide within the limiting block 9, and then drives the guiding rod 91 to slide within the limiting block 9. At this time, due to the restriction of the second spring 92, through the guiding of multiple guiding plates 93, the steel reinforcement cage 2 is smoothly pushed to the central position of the anti-counterposition offset mechanism main body 1. At this time, the user can release the restriction on the first group of steel reinforcement cages 2. At this time, under the support of the limiting block 9, the first group of steel reinforcement cages 2 remains stable within the anti-counterposition offset mechanism main body 1. At this time, the user can continue to hoist the second group of steel reinforcement cages 2. Due to the restriction of the anti-counterposition offset mechanism main body 1, when the user docks the second group of steel reinforcement cages 2, the first group of steel reinforcement cages 2 can be supported, which is convenient for the user to better dock the steel reinforcement cages 2. When the docking of the two groups of steel reinforcement cages 2 is completed;

[0059] Similarly, by reversely driving the right-angle motor 3, the first driven gear 4 rotates reversely, thereby moving the limiting block 9 into the anti-position-offset mechanism main body 1. At the same time, the brake block 8 no longer contacts the inner wall of the foundation pile pit. At this time, the transmission rod 7 rotates into the anti-position-offset mechanism main body 1. At this time, the user can continue to hoist the two butt-jointed steel reinforcement cages 2 downward. When the spiral bars at the end of the steel reinforcement cage 2 are higher than the upper part of the limiting block 9, the user repeats the above operations to continue butt-jointing the two steel reinforcement cages 2.

[0060] Although the embodiments of the present invention have been shown and described, the specific embodiments are only explanations of the present invention and not limitations thereof. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
