Description

Technical Field

[0001] This utility model relates to the field of steel pipe pile construction technology, and in particular to an adjustable PLC steel pipe pile verticality control device. Background Technology

[0002] Steel pipe piles are tubular pile foundation components made of rolled or welded steel. Their cross-sections are mostly circular, but some are square or irregular. They are prefabricated in a factory and then transported to the construction site, where they are driven into the underground soil or rock layers by piling equipment to form a pile foundation that bears the load of the superstructure.

[0003] In existing technologies, corresponding correction mechanisms are typically installed on the top and outer side of the steel pipe pile to detect and correct its verticality during installation. However, when the steel pipe pile needs to be driven to a greater depth, a new steel pipe pile is usually welded to the top of the existing pile that is already embedded in the underground soil or rock. To ensure a stable weld between the two piles, corresponding notches and protrusions are usually provided at the weld ends to form a tenon joint structure. Therefore, for the bottom steel pipe pile, its top is not neat and it needs to be driven into the underground soil or rock, resulting in a small external surface area. Existing correction mechanisms are insufficient for correcting the verticality of steel pipe piles with this type of structure.

[0004] Therefore, this application provides an adjustable PLC steel pipe pile verticality control device to meet the requirements. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an adjustable PLC steel pipe pile verticality control device to solve the problem of difficulty in correcting the deviation of steel pipe piles with butt joint structure.

[0008] Protective shell and steel pipe pile body;

[0009] Several support frames are provided, all of which are rotatably connected to the bottom of the protective shell;

[0010] The number of clamping plates is twice that of the support frame, and they are all slidably connected to the corresponding support frame;

[0011] The telescopic rod is fixedly connected to the bottom of the protective shell and extends downward into the interior of the steel pipe pile body;

[0012] A crossbar is fixedly connected to the end of the telescopic rod away from the protective shell and is perpendicular to the telescopic rod.

[0013] Two adjusting caps are provided, which are threadedly connected to both ends of the crossbar respectively;

[0014] Two elastic elements are provided, both located inside the crossbar, and one end of each element is fixedly connected to the crossbar.

[0015] Two pressure sensors are provided, both located inside the corresponding adjustment cap on the same side, and both are fixedly connected to the corresponding elastic element on the same side. The pressure sensors are used to detect the elastic force of the elastic element.

[0016] Preferably, the bottoms of the plurality of support frames are all flush and in the same plane.

[0017] Preferably, each of the support frames has two clamping plates slidably connected to it, and each of the two clamping plates on the support frame is threaded with a locking bolt. The two clamping plates on each support frame are located on the inner and outer sides of the steel pipe pile body, respectively.

[0018] Preferably, the telescopic rod is perpendicular to the plane at which the bottom of the plurality of clamping plates is located, and the telescopic rod is completely located within the body of the steel pipe pile.

[0019] Preferably, the connecting block is fixedly connected to the side of the pressure sensor away from the elastic element;

[0020] A rotary joint is rotatably connected to the side of the connecting block away from the pressure sensor, and the end of the rotary joint away from the connecting block is rotatably connected to the adjusting cap;

[0021] The control component is fixedly connected inside the protective housing;

[0022] An inclination sensor is fixedly connected inside the inclination sensor and parallel to the bottom of the support frame, used to provide the control component with information on its verticality.

[0023] Preferably, the clamp is held on one side of the steel pipe pile body to fix the steel pipe pile body and transmit static pressure.

[0024] The first rotating arm is rotatably connected to the top of the clamp and is used to adjust the angle of the steel pipe pile body held by the clamp by its own rotation;

[0025] The second rotating arm is rotatably connected to the end of the first rotating arm away from the clamp, and is used to adjust the angle of the steel pipe pile body held by the clamp by its own rotation;

[0026] The third rotating arm is rotatably connected to the end of the second rotating arm away from the first rotating arm, and is used to adjust the angle of the steel pipe pile body held by the clamp by its own rotation.

[0027] Preferably, the first adjusting rod has one end rotatably connected to the first rotating arm and the other end rotatably connected to the second rotating arm, and is used to adjust the angle between the first rotating arm and the second rotating arm by extending and retracting itself;

[0030] This invention provides an adjustable PLC-based steel pipe pile verticality control device. Compared with the prior art, it has the following advantages:

[0031] 1. By using several rotatable support frames, along with clamping plates, the steel pipe pile is slidably clamped from both the inside and outside sides and fixed with locking bolts. At the same time, the telescopic rod drives the crossbar and adjusting cap to abut against the inner wall inside the steel pipe pile, so that the entire device is located inside the steel pipe pile and can be stably installed on the steel pipe pile with an uneven top due to the docking structure. This solves the problem that existing correction mechanisms are difficult to install and fix due to the uneven top of the steel pipe pile.

[0032] 2. The verticality of the steel pipe pile is detected in real time by the tilt sensor. After receiving the detection information, the control component adjusts the extension and retraction of the first and second adjusting rods to adjust the angle between the first and second rotating arms and the second and third rotating arms, thereby driving the clamp to adjust the angle of the steel pipe pile. This realizes the automatic correction of the steel pipe pile with the docking machine structure and the small outer area, thus facilitating the correction of the tilted steel pipe pile.

[0040] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0041] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0042] Reference Figures 1-5 An adjustable PLC steel pipe pile verticality control device includes:

[0043] The protective shell 10 and the steel pipe pile body 20 are used to protect their internal components. The protective shell 10 can be made of engineering plastics, which are suitable for dry and normal temperature construction environments and have moderate cost. Polycarbonate can also be used, which has excellent insulation and good heat resistance and is suitable for high temperature and outdoor environments. The steel pipe pile body 20 can be selected with a flush top or a raised top.

[0044] Support frames 11 are provided in several units, all of which are rotatably connected to the bottom of the protective shell 10. They can be set to three units, which are evenly erected on the top of the steel pipe pile body 20 to ensure relatively stable support with a smaller number of units.

[0045] The number of clamping plates 111 is twice that of the support frame 11, and they are all slidably connected to the corresponding support frame 11. The clamping plates 111 can slide in the support frame 11 through the guide rail, which can provide guidance for the clamping plates 111, and also provide support and limit the clamping plates 111.

[0046] The telescopic rod 12 is fixedly connected to the bottom of the protective shell 10 and extends downward into the interior of the steel pipe pile body 20. The telescopic rod 12 is a spring pin positioning type, but pneumatic rods, hydraulic rods, etc. can also be used. Its extension and contraction and the fixation of its own length after extension and contraction are controlled by the external equipment of the control component 17.

[0047] The crossbar 13 is fixedly connected to the end of the telescopic rod 12 away from the protective shell 10 and is perpendicular to the telescopic rod 12. Alternatively, the crossbar 13 can be rotatably connected to the telescopic rod 12, allowing workers to freely choose the point of contact between it and the steel pipe pile body 20.

[0048] Two adjusting caps 14 are provided, which are threaded to both ends of the crossbar 13 respectively. They can be configured to be threaded to the outer walls of both ends of the crossbar 13, or they can be configured to be threaded to the inner walls of both ends of the crossbar 13.

[0049] Two elastic elements 15 are provided, both located inside the crossbar 13, with one end of each element fixedly connected to the crossbar 13. Alternatively, one element can be provided, with both ends fixedly connected to two pressure sensors 16 on either side. The elastic element 15 applies elastic force to the adjusting cap 14 through the pressure sensors 16, connecting block 161, and rotating joint 162, causing the adjusting cap 14 to be subjected to a force in the same direction as its own axis of rotation. This increases the friction between the adjusting cap 14 and the internal and external threads of the crossbar 13, preventing the adjusting cap 14 from rotating on its own when subjected to external forces. This results in the rod-shaped structure composed of the crossbar 13 and the adjusting cap 14 becoming loose.

[0050] Two pressure sensors 16 are provided, both located inside the corresponding adjusting caps 14 on the same side and fixedly connected to the corresponding elastic members 15 on the same side. The pressure sensors 16 are used to detect the elastic force of the elastic members 15. When the data detected by the two pressure sensors 16 are different, it means that the adjusting cap 14 with the smaller data has not fully extended to its limit and has not achieved a complete fixing effect.

[0051] The bottoms of several support frames 11 are all flush and in the same plane, so that the protective shell 10 can remain horizontal after the support frame 11 is erected on top of the steel pipe pile body 20.

[0052] Each support frame 11 has two clamping plates 111 slidably connected to it, and each of the two clamping plates 111 on each support frame 11 is threaded with a locking bolt 112. The two clamping plates 111 on each support frame 11 are located on the inner and outer sides of the steel pipe pile body 20, respectively. By rotating the locking bolt 112, the two clamping plates 111 come into contact with each other and are clamped on the inner and outer sides of the steel pipe pile body 20, thereby achieving a fixing effect.

[0053] The telescopic rod 12 is perpendicular to the plane at the bottom of several clamping plates 111, and the telescopic rod 12 is completely located within the steel pipe pile body 20.

[0054] Connecting block 161 is fixedly connected to the side of pressure sensor 16 away from elastic element 15;

[0055] Rotary joint 162 is rotatably connected to the side of connecting block 161 away from pressure sensor 16. The end of rotary joint 162 away from connecting block 161 is rotatably connected to adjusting cap 14. Through the rotatable connection between rotary joint 162 and adjusting cap 14, the problem of elastic element 15 being twisted due to rotation of adjusting cap 14 through rotary joint 162, connecting block 161 and pressure sensor 16 is avoided, which would cause damage to elastic element 15.

[0056] Control component 17 is fixedly connected inside the protective housing 10;

[0057] Inclination sensor 18 is fixedly connected inside the tilt sensor 18 and is parallel to the bottom of the support frame 11, and is used to provide the control component 17 with its own verticality status.

[0058] The clamp 30 is clamped on one side of the steel pipe pile body 20 and is used to fix the steel pipe pile body 20 and transmit static pressure. It can clamp the steel pipe pile body 20 by extrusion pressure or by bolt and screw structure.

[0059] The first rotating arm 31 is rotatably connected to the top of the clamp 30 and is used to adjust the angle of the steel pipe pile body 20 held by the clamp 30 by its own rotation.

[0060] The second rotating arm 32 is rotatably connected to the end of the first rotating arm 31 away from the clamp 30, and is used to adjust the angle of the steel pipe pile body 20 held by the clamp 30 by its own rotation.

[0061] The third rotating arm 33 is rotatably connected to the end of the second rotating arm 32 away from the first rotating arm 31, and is used to adjust the angle of the steel pipe pile body 20 held by the clamp 30 by its own rotation.

[0062] The first adjusting rod 19 is rotatably connected at one end to the first rotating arm 31 and at the other end to the second rotating arm 32. It is used to adjust the angle between the first rotating arm 31 and the second rotating arm 32 by extending and retracting itself. If the steel pipe pile body 20 is small, a cylinder can also be used.

[0063] The second adjusting rod 191 is rotatably connected at one end to the second rotating arm 32 and at the other end to the third rotating arm 33. It is used to adjust the angle between the second rotating arm 32 and the third rotating arm 33 by extending and retracting itself. If the steel pipe pile body 20 is small, a cylinder can also be used.

[0064] The control unit 17 is electrically connected to two pressure sensors 16, an inclination sensor 18, a first adjusting rod 19, and a second adjusting rod 191. It is used to acquire the parameters of the pressure sensors 16 and regulate the extension and retraction of the first adjusting rod 19 and the second adjusting rod 191. The control unit 17 can be connected to interactive devices via Wi-Fi, Bluetooth, etc., to directly transmit the information it receives to the staff and help the staff adjust the verticality of the steel pipe pile body 20.

[0065] Working process and principle: The telescopic rod 12 and adjusting cap 14 are placed inside the steel pipe pile body 20. Simultaneously, several support frames 11 are rotated to ensure they are evenly distributed on the top of the steel pipe pile body 20. The locking bolts 112 are rotated to clamp several clamping plates 111 onto the inner and outer sides of the steel pipe pile body 20, initially fixing the protective shell 10. Then, the telescopic rod 12 is adjusted to a suitable length, and the two adjusting caps 14 are rotated to move towards the side wall of the steel pipe pile body 20 until they are fully in contact with the inner wall. At this point, the diameter of the rod-like structure formed by the crossbar 13 and the two adjusting caps 14 is close to the inner diameter of the steel pipe pile body 20, and the rod-like structure is also fixed. The protective shell 10 is then completely fixed. Since the bottom of the support frame 11 is flush with the ground and the rod-like structure formed by the crossbar 13 and the adjusting caps 14 is horizontal, the tilt sensor 18 is also in a parallel state. When the steel pipe pile body 20 tilts, the tilt angle sensor 18 sends the tilt angle information to the tilt angle sensor 18. The tilt angle sensor 18 controls the extension and retraction of the first adjusting rod 19 and the second adjusting rod 191, thereby adjusting the included angle of the first rotating arm 31 and the second rotating arm 32, the second rotating arm 32 and the third rotating arm 33, and thus adjusting the angle of the steel pipe pile body 20, so that it returns to a state perpendicular to the working surface.

[0066] Therefore, although the present invention has been described herein with reference to specific embodiments thereof, freedom of modification, various changes and substitutions are also within the scope of the above disclosure, and it should be understood that in some cases, certain features of the present invention may be adopted without departing from the scope and spirit of the invention and without corresponding use of other features. Thus, many modifications can be made to adapt a particular environment or material to the essential scope and spirit of the present invention. The present invention is not intended to be limited to the specific terms used in the following claims and / or the specific embodiments disclosed as the best mode of carrying out the present invention, but the present invention will include any and all embodiments and equivalents falling within the scope of the appended claims. Therefore, the scope of the present invention will be determined only by the appended claims.
