[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] Embodiment 1:

[0037] refer to Figure 1-Figure 9 As shown, the utility model provides a purlin-type positioning tool, which is used to accurately control the offset and spacing between multiple steel pipe piles 11 arranged along a straight line, and simplify the pile sinking construction procedure of the steel pipe piles 11. The positioning tool includes a support frame 2, a limit assembly and a positioning assembly connected to the support frame 2. The support frame 2 includes two longitudinal beams 21 arranged opposite to each other, that is, the two longitudinal beams 21 are parallel to each other and arranged at intervals.

[0038] The limiting assembly includes two hoops 4 provided at both ends of the longitudinal beam 21 in the length direction. The two hoops 4 are connected between the two longitudinal beams 21, and can be connected to the top surfaces of the two longitudinal beams 21, or can be connected to the bottom surfaces of the two longitudinal beams 21. The positional relationship between the two hoops 4 is consistent with the positional relationship between the two preset auxiliary piles 11_1, that is, the plane distance between the centers of the two hoops 4 is equal to the plane distance between the centers of the two auxiliary piles 11_1. More specifically, the length direction of the longitudinal beam 21 can be set to be parallel to the center line of the two preset auxiliary piles 11_1, so that the center line of the two hoops 4 is parallel to the length direction of the longitudinal beam 21. The inner diameter of the hoop 4 is adapted to the outer diameter of the auxiliary pile 11_1; it can be understood that the spacing between the two longitudinal beams 21 is greater than the inner diameter of the hoop 4. Further explanation, through the setting of the two hoops 4, the limiting assembly in the positioning tool can reliably hold the two preset auxiliary piles 11_1, thereby realizing the installation and precise positioning of the positioning tool on the two preset auxiliary piles 11_1.

[0039] The positioning assembly includes a plurality of positioning frames 3 connected between two longitudinal beams 21 and arranged at intervals along the length direction of the longitudinal beams 21, that is, the plurality of positioning frames 3 are arranged along a straight line; the number of positioning frames 3 is at least two, and the number of positioning frames 3 in this embodiment is five, but it is not limited thereto. The plurality of positioning frames 3 can be connected to the top surface of the two longitudinal beams 21, or can be connected to the bottom surface of the two longitudinal beams 21; it should be noted that all positioning frames 3 in the positioning assembly are located between the two clamps 4 of the limiting assembly. The positional relationship between the plurality of positioning frames 3 is consistent with the positional relationship between the plurality of steel pipe piles 11_2 to be sunk arranged along a straight line, that is, the plane spacing between the centers of the plurality of positioning frames 3 is equal to the plane spacing between the centers of the plurality of steel pipe piles 11_2 to be sunk arranged along a straight line, and the centers of the plurality of positioning frames 3 are located on the same straight line. More specifically, the centers of the two preset auxiliary piles 11_1 can be set to be located on the same straight line as the centers of the plurality of steel pipe piles 11_2 to be sunk arranged along a straight line, so that the centers of the two clamps 4 and the centers of the plurality of positioning frames 3 are also located on the same straight line.

[0040] Furthermore, each positioning frame 3 includes a positioning frame 31 and at least three guide wheel groups 32 arranged at equal angles around the center of the positioning frame 31; the center of the positioning frame 31 is also the center of the positioning frame 3. The positioning frame 31 is connected to the two longitudinal beams 21. It can be understood that the positioning frame 31 has a receiving cavity that passes through from top to bottom. Considering the manufacturing convenience of the positioning frame 31 and the connection strength requirements between the positioning frame 31 and the two longitudinal beams 21, the overall shape of the positioning frame 31 can be designed to be square. The square positioning frame 31 can be welded with I-beams, so that the through-opening shape of the receiving cavity of the positioning frame 31 is also square; all the guide wheel groups 32 on the positioning frame 31 are used to contact the outer wall of the steel pipe pile 11_2 to be sunk that passes through the positioning frame 31, so as to jointly clamp and position the steel pipe pile 11_2 to be sunk and guide it during sinking; that is, the size of the receiving cavity on the positioning frame 31 is larger than the steel pipe pile 11_2 to be sunk. The outer diameter of the pipe pile 11_2 and the guide wheel groups 32 are all protruding toward the center of the positioning frame 31, and all the guide wheel groups 32 on the positioning frame 31 jointly form a clamping space for the steel pipe pile 11_2 to be sunk; specifically, the number of guide wheel groups 32 on each positioning frame 31 can be set to four, which are arranged at 90 degree intervals around the center of the positioning frame 31, and can be arranged at the four corners of the positioning frame 31, and the distance between the two opposing guide wheel groups 32 is consistent with the outer diameter of the steel pipe pile 11_2 to be sunk, thereby enabling all the guide wheel groups 32 on each positioning frame 31 to contact the outer wall of the steel pipe pile 11_2 to be sunk, so as to jointly clamp, position and guide the steel pipe pile 11_2 to be sunk.

[0041] It should be noted that, through the specific arrangement of multiple positioning frames 3 arranged along a straight line, the centers of multiple steel pipe piles 11_2 to be sunk are located on the same straight line; when the positioning tool is installed and positioned on the two preset auxiliary piles 11_1 through the limit assembly, the sinking positions of the multiple steel pipe piles 11_2 to be sunk can be accurately positioned, so there is no need to position them one by one during pile sinking, and accurate control of the offset and spacing between the multiple steel pipe piles 11_2 to be sunk arranged along a straight line can be achieved, thereby simplifying the construction procedure of the steel pipe piles 11 and improving the efficiency and quality of the pile sinking operation.

[0042] Furthermore, two anti-rotation grooves 311 are provided on the inner wall of each positioning frame 31 for accommodating the lock buckles 12 on both sides of the steel pipe piles 11_2 to be sunk, and the shape and size of the anti-rotation grooves 311 are adapted to the lock buckles 12 on the steel pipe piles 11_2 to be sunk; through the provision of multiple anti-rotation grooves 311 on the positioning frames 31, when the multiple steel pipe piles 11_2 to be sunk are inserted one by one into the multiple positioning frames 3 of the positioning tooling, the position of the lock buckle 12 on each steel pipe pile 11_2 to be sunk can be quickly and accurately controlled, and the steel pipe piles 11_2 to be sunk can be prevented from rotating themselves during piling, and the position of the lock buckles 12 on the multiple steel pipe piles 11_2 to be sunk can be kept consistent, which is convenient for the subsequent driving of the steel sheet piles 13.

[0043] In the above-mentioned exemplary embodiment, the installation and precise positioning of the positioning tool on the two preset auxiliary piles 11_1 are realized through the setting of the limiting component; the centers of the multiple steel pipe piles 11_2 to be sunk are located on the same straight line through the setting of the positioning component; therefore, when the positioning tool is installed and positioned on the two preset auxiliary piles 11_1 through the limiting component, the pile sinking positions of the multiple steel pipe piles 11_2 to be sunk can be accurately located, and the offset and spacing between the multiple steel pipe piles 11_2 to be sunk arranged along a straight line can be accurately controlled, thereby solving the problems of complicated construction procedures, low operating efficiency, and difficult control of offset and spacing between multiple steel pipe piles 11 under the existing pile sinking positioning method, improving the accuracy of pile sinking and preventing the pile body from rotating, meeting the pile sinking accuracy requirements and ensuring smooth pile sinking, and improving the efficiency and quality of pile sinking operations.

[0044] refer to Figure 1-Figure 5 , Figure 8 As shown, in some embodiments, each guide wheel group 32 includes a mounting seat 321 and a guide roller 322. The mounting seat 321 is connected to the positioning frame 31; the guide roller 322 is rotatably connected to the side of the mounting seat 321 facing the center of the positioning frame 31, and the direction of the wheel axle 3221 of the guide roller 322 is perpendicular to the axial direction of the steel pipe pile 11_2 to be sunk. The wheel surface of the guide roller 322 of all guide wheel groups 32 is used to contact the outer wall of the steel pipe pile 11_2 to be sunk. Further explanation, because the guide roller 322 can rotate around its wheel axle 3221, under the rotation and guiding action of all guide rollers 322, the steel pipe pile 11_2 to be sunk can be easily inserted into the positioning frame 3, and it is ensured that the steel pipe pile 11_2 to be sunk slides smoothly relative to the positioning frame 3 during the subsequent pile sinking, thereby improving the efficiency of the pile sinking operation.

[0045] refer to Figure 1-Figure 5 , Figure 8As shown, in some embodiments, each guide wheel group 32 further includes a slide 323 and a fine-tuning screw 324. The slide 323 is slidably connected to the mounting seat 321 in a direction toward the center of the positioning frame 31, and the guide roller 322 is rotatably connected to one end of the slide 323 facing the center of the positioning frame 31. One end of the fine-tuning screw 324 is connected to a side of the slide 323 away from the guide roller 322, and the other end passes through the mounting seat 321 and protrudes out of the mounting seat 321; the fine-tuning screw 324 is threadedly connected to the mounting seat 321. When the steel pipe pile 11_2 to be sunk is inserted into the positioning frame 3, the slide 323 is driven to slide on the mounting seat 321 by rotating the fine-tuning screw 324, thereby driving the guide roller 322 to move, so as to fine-tune the contact state between the wheel surface of the guide roller 322 and the steel pipe pile 11_2 to be sunk, thereby enabling the positioning tool to have a fine-tuning function, thereby further improving the positioning accuracy of multiple steel pipe piles 11_2 to be sunk, and the control accuracy of the offset and spacing between multiple steel pipe piles 11_2 to be sunk.

[0046] In some embodiments, the wheel surface of the guide roller 322 is made of rubber material to avoid damage or destruction to the anti-corrosion coating of the steel pipe pile 11_2 to be sunk during the pile sinking process.

[0047] refer to Figure 2 , Figure 3 , Figure 6 As shown, in some embodiments, two anti-rotation components 33 are convexly disposed on the inner wall of each positioning frame 31 , and each anti-rotation component 33 includes two anti-rotation blocks 331 disposed opposite to each other, and an anti-rotation groove 311 is formed between the two anti-rotation blocks 331 .

[0048] refer to Figure 3 , Figure 7 As shown, in some embodiments, two limiting grooves 43 for accommodating the lock buckles 12 on both sides of the preset auxiliary pile 11_1 are recessed on the inner wall of each clamp 4, and the shape and size of the limiting grooves 43 are adapted to the lock buckles 12 on the auxiliary pile 11_1; further, the two limiting grooves 43 on the clamp 4 are aligned with the two anti-rotation grooves 311 on the positioning frame 31. In actual construction, the steel pipe pile 11 that has been completed can be used as the auxiliary pile 11_1; when the positioning tool is installed on the two steel pipe piles 11 that have been completed, the limiting grooves 43 on the two clamps 4 are respectively aligned with the lock buckles 12 on the two steel pipe piles 11 that have been completed, so that when the positioning tool is installed and positioned on the two steel pipe piles 11 that have been completed, the positions of the lock buckles 12 on the multiple steel pipe piles 11_2 to be sunk are also kept consistent with the positions of the lock buckles 12 on the steel pipe piles 11 that have been completed.

[0049] refer to Figure 3 , Figure 7 , Figure 8As shown, in some embodiments, each hoop 4 includes two hoop bodies 41 arranged in an opposing manner, and both ends of the two hoop bodies 41 are connected by a bolt assembly 42. A limiting groove 43 is respectively recessed on the inner wall of each hoop body 41. This illustrative embodiment realizes the openable and closable connection of the hoop 4. When positioning the positioning tool on two preset auxiliary piles 11_1, the contact state between the hoop 4 and the auxiliary pile 11_1 can be adjusted through the bolt assembly 42, so that the two hoops 4 respectively hold the two auxiliary piles 11_1 tightly, thereby realizing the installation and precise positioning of the positioning tool on the two auxiliary piles 11_1.

[0050] In some embodiments, a rubber pad is attached to the inner wall of the hoop 4, and the hoop 4 contacts the outer wall of the auxiliary pile 11_1 through the rubber pad, avoiding damage or destruction to the anti-corrosion coating of the auxiliary pile 11_1.

[0051] Reference Fig. 9 As shown, in some embodiments, the hoop 4 includes a top plate 401, a bottom plate 402, and side plates 403 connected between the two, so that the cross-section of the hoop 4 is in a C shape; a plurality of reinforcing ribs 404 are also connected between the top plate 401 and the bottom plate 402, thereby enhancing the structural strength of the hoop 4 itself.

[0052] Reference Figure 2 、 Figure 3 As shown, in some embodiments, the support frame 2 further includes a plurality of cross braces 22 connected between the two longitudinal beams 21, and each cross brace 22 is perpendicularly connected between the two longitudinal beams 21; each positioning frame 3 is provided with cross braces 22 on both sides in the length direction of the longitudinal beam 21; thereby improving the overall structural strength of the support frame 2 and ensuring the overall structural stability of the positioning tool.

[0053] Combined with Figure 1-Figure 9 As shown, briefly describe the main steps when using the collar-type positioning tool of Embodiment 1 of the present utility model for driving a plurality of steel pipe piles 11 arranged in a straight line:

[0054] 1) First, use devices such as GPS devices and total stations to drive two auxiliary piles 11_1, and the distance between the two auxiliary piles 11_1 is greater than the span of a plurality of steel pipe piles 11_2 to be driven in a straight line; observe the deviation and verticality of the pile body during the driving process to ensure that the two auxiliary piles 11_1 are accurately positioned and the verticality is qualified; weld a bracket or set a clamp at the preset height position of the auxiliary pile 11_1; in actual construction, the already driven steel pipe piles 11 can be used as the auxiliary piles 11_1.

[0055] 2) Then, the positioning tool is installed on the two auxiliary piles 11_1; specifically, the centers of the two hoops 4 are aligned with the centers of the two auxiliary piles 11_1 respectively, and then the positioning tool is lowered until the bottom of the hoops 4 is pressed on the welded bracket or clamp of the auxiliary pile 11_1; the contact state between the hoops 4 and the auxiliary pile 11_1 is adjusted by the bolt assembly 42 to ensure that the two hoops 4 reliably hold the two auxiliary piles 11_1 respectively, so as to realize the installation and precise positioning of the positioning tool on the preset two auxiliary piles 11_1;

[0056] 3) Then, the skip driving method is used to carry out the pile driving construction of multiple steel pipe piles 11_2 to be sunk; specifically, the steel pipe piles 11_2 to be sunk are hoisted above the positioning tooling, and the center of the steel pipe pile 11_2 to be sunk is aligned with the center of the positioning frame 3 and the lock buckle 12 is aligned with the anti-rotation groove 311, and the steel pipe pile 11_2 to be sunk is lowered; when the steel pipe pile 11_2 to be sunk is inserted into the positioning frame 3, the contact state between the wheel surface of each guide roller 322 and the steel pipe pile 11_2 to be sunk is finely adjusted by the fine-tuning screw 324 to ensure that the crimping state is consistent, and then the steel pipe pile 11_2 to be sunk is driven until the steel pipe pile 11_2 to be sunk is inserted into place; after completing the pile driving operation of multiple steel pipe piles 11_2 to be sunk, the positioning tooling is hoisted off the auxiliary pile 11_1.

[0057] It should be noted that the purlin-type positioning tool of the first embodiment of the utility model is suitable for pile driving operations in pile driving construction areas with good geological conditions or when the construction personnel are highly skilled in operation; during the pile driving process, the verticality of the steel pipe pile 11_2 to be driven is controlled by adjusting the angle of the vibrating hammer, controlling the penetration speed, retaining vibration, etc. by shaking the rope.

[0058] Embodiment 2:

[0059] refer to Figure 1-Figure 10 As shown, based on the first embodiment, the utility model also provides a purlin-type positioning tool, which is suitable for pile driving operations in pile driving construction areas with average or poor geological conditions, or when the construction personnel have average operating proficiency.

[0060] The purlin-type positioning tooling of the second embodiment of the present utility model adopts an upper and lower double-layer structure, specifically: the number of the supporting frames 2 is two, the two supporting frames 2 are arranged at intervals, and the upper and lower supporting frames 2 are connected by a plurality of vertical beams 23. The number of the limiting components is two groups, the two groups of limiting components are respectively connected to the upper and lower supporting frames 2, and the clamps 4 in the two groups of limiting components are arranged in a pair of upper and lower centers; the number of the positioning components is two groups, the two groups of positioning components are respectively connected to the upper and lower supporting frames 2, and the positioning frames 3 in the two groups of positioning components are arranged in a pair of upper and lower centers; it can be understood that the center line direction of the upper and lower clamps 4 is consistent with the center line direction of the upper and lower positioning frames 3.

[0061] It is further explained that, by setting the upper and lower groups of limit assemblies, the center line direction of the upper and lower clamps 4 and the center line direction of the upper and lower positioning frames 3 are strictly consistent with the axial direction of the auxiliary pile 11_1; therefore, during the pile sinking operation, when the positioning tooling reliably clamps the two auxiliary piles 11_1, the axial direction of the steel pipe pile 11_2 to be sunk can be strictly consistent with the axial direction of the auxiliary pile 11_1, thereby quickly realizing accurate control of the verticality of the steel pipe pile 11_2 to be sunk, and reducing the difficulty of controlling the verticality of the steel pipe pile 11_2 to be sunk.

[0062] Furthermore, in the second embodiment of the utility model, the height difference H between the upper and lower double-layer support frames 2 is ≥ L / 0.5% to meet the verticality control requirements; where L is the preset adjustable range value of the centering deviation of the upper and lower layers. For example, when L = 20mm, the height difference H between the upper and lower layers of the support frames 2 is not less than 4m.

[0063] To sum up, the purlin-type positioning tool of the utility model can accurately control the deviation and spacing between multiple steel pipe piles 11 arranged along a straight line through the setting of the limit component and the positioning component, simplify the construction procedure of the steel pipe piles 11, and improve the efficiency and quality of the pile driving operation; practice has proved that after using the purlin-type positioning tool of the utility model for pile driving operation, the average daily number of piles driven is increased from 1 to 2.5, and a maximum of 3 piles can be completed, and the efficiency of the pile driving operation is significantly improved.
