Description

Technical Field

[0001] This utility model relates to the field of power transmission line technology, and in particular to a circular bearing platform anchor positioning device. Background Technology

[0002] Rock anchors for power transmission lines are a geotechnical engineering technique used to reinforce tower foundations. By embedding high-strength anchors (steel bars / strands) into the rock strata and grouting them in place, they enhance the foundation's pull-out and overturning resistance, ensuring the stability of the transmission towers under complex geological conditions and wind loads. Rock anchors perform particularly well in complex rock geological scenarios such as mountainous areas and steep slopes. They are a key technology for "rooting" power transmission lines in complex terrain, achieving maximum stability with minimal disturbance.

[0003] Foundation-type anchor bolts typically include square and circular foundations. Circular foundations offer the advantage of saving concrete, but positioning the anchor bolts under the foundation is difficult. Current technology usually involves the construction unit marking out the center of the circular foundation, then manually using ropes to determine a fixed distance from the foundation center, and finally tracing the anchor bolt positions based on a perceived uniform angle. However, this positioning method is inconvenient and often lacks precision, resulting in significant errors.

[0004] Therefore, how to provide a circular pier anchor bolt positioning device that is easy to position and accurate is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] This utility model embodiment addresses the shortcomings of traditional anchor bolt positioning in actual construction scenarios, bringing multi-dimensional practical value.

[0025] The following is combined with Figures 1-3 The circular foundation anchor positioning device of this utility model includes a support 1, a fixing ring 3, multiple connecting rods 4 and an indicator rod 5.

[0026] The support 1 is fixedly positioned at the center of the circular base, and angle markings are provided on the support 1. The fixing ring 3 is circular and concentrically positioned with the support 1. The fixing ring 3 is located on the outer periphery of the support 1. Multiple connecting rods 4 are distributed on the outer periphery of the support 1. One end of each connecting rod 4 is connected to the support 1, and the other end is connected to the fixing ring 3. This ensures that the center of the fixing ring 3 coincides with the center of the base, and also ensures that the radial position of the fixing ring 3 does not shift. The first end of the indicator rod 5 is rotatably positioned at the center of the support 1, and the second end of the indicator rod 5 extends to the top of the fixing ring 3. When the second end of the indicator rod 5 abuts against the top of the fixing ring 3, the radial distance of the anchor rod can be precisely controlled by the preset diameter of the fixing ring 3, avoiding the problem of some anchor rods being too close or too far due to radial offset.

[0027] When in use, select the specified diameter fixing ring 3 as needed, and choose the position of the first anchor rod on the fixing ring 3. Based on the number of anchor rods, calculate the angle between every two anchor rods and the center of the bearing platform. Based on the position of the first anchor rod, rotate the indicator rod clockwise or counterclockwise by the corresponding degree, referring to the angle scale on the support 1. The intersection of the indicator rod 5 and the fixing ring 3 is the center position of the second anchor rod. This process can be repeated to locate all anchor rod positions. Workers only need to align the indicator rod 5 with the scale value to directly mark the angle position of the anchor rod, completely replacing the traditional, crude method of repeatedly measuring with a handheld protractor and using a string, thus avoiding angle deviations.

[0028] Once the device is assembled, only one worker needs to rotate the indicator rod 5 and align it with the scale to mark the anchor bolt position, eliminating the need for multiple workers and significantly reducing labor input. The angle scale is directly integrated into the support 1, eliminating the need to carry additional tools such as protractors and measuring tapes. Furthermore, the rotation, alignment, and marking process of the indicator rod 5 can complete the positioning of a single anchor bolt within seconds, which is many times more efficient than traditional methods, and is especially suitable for circular foundations with a large number of anchor bolts.

[0029] In addition, due to the improved positioning accuracy, there is no need to adjust the drilling position or cut the steel bars during subsequent anchor installation due to positional deviations, avoiding rework operations such as secondary drilling or steel bar reconstruction, and shortening the construction cycle.

[0030] In one feasible embodiment of this utility model, an anchor rod 6 is also included, which is fixedly installed at the center of the circular foundation and buried underground, forming a mechanical interlock with the foundation soil. It has strong pull-out resistance and lateral force resistance, ensuring that the support does not tilt or shift even when subjected to vibration impact or mechanical collision during concrete pouring, thus guaranteeing the accuracy of subsequent angle scale and indicator rod 5 positioning from the source. The top of the anchor rod 6 is connected to the support 1, forming a three-dimensional stable structure. Together with the support 1, connecting rod 4, and fixing ring 3 on the ground, it forms a three-dimensional frame of underground anchoring and ground radiation, upgrading the device from being fixed solely by ground friction to being rigidly connected to the foundation, thus improving its resistance to lateral vibration. Before construction, the anchor rod 6 only needs to be accurately buried in the design center by laying out lines. When installing the support 1 later, it can be directly connected to the top of the anchor rod 6 without secondary adjustment of the center position, shortening the installation time of the support 1.

[0031] In one feasible embodiment of this utility model, a cap 7 is installed on the top of the first end of the indicator rod 5. The diameter of the cap 7 is larger than the diameter of the shaft hole of the support 1. When the indicator rod 5 is inserted into the shaft hole of the support 1, the cap 7 can be firmly locked on the top of the support 1, forming a two-way fixation with the shaft hole constraining below and the cap 7 blocking above, completely preventing the indicator rod 5 from falling off due to rotational inertia or accidental lifting.

[0032] In one feasible embodiment of this utility model, the fixing ring 3 includes multiple arc-shaped segments, which are connected end to end to form a closed ring. The multiple arc-shaped segments can be disassembled and stacked for easy loading into a transport vehicle without the need for special transport vehicles; at the same time, the disassembled arc-shaped segments are lighter in weight, which can be carried by hand by workers, making them suitable for narrow roads at construction sites.

[0033] Furthermore, during the assembly process, if a segment of the curved section deviates from its position, that segment can be finely adjusted individually without needing to move the entire ring. In contrast, if the integral fixing ring is misaligned, the entire ring must be lifted and adjusted, which is difficult to operate and prone to colliding with other components. The curved section significantly reduces the difficulty of controlling the installation accuracy.

[0034] In one feasible embodiment of this utility model, adjacent arc-shaped segments are detachably connected by sleeves 2. Alternatively, the beginning and end of the arc-shaped segments can be joined using a concave-convex fit and threaded connection, or by using snap-fit ​​and welding assistance. The radial runout after splicing can be controlled within a certain range, with a small concentricity error, meeting the accuracy requirements for anchor positioning. Multiple connecting rods 4 evenly connect the support 1 and the arc-shaped segments. The tension of the connecting rods 4 further constrains the splicing gap of the arc-shaped segments, making the ring body a rigid whole that is spliced ​​but not loose, resisting lateral forces during construction and ensuring accurate and stable radial positioning.

[0035] In one feasible embodiment of this utility model, the fixing ring 3 includes various specifications. The fixing ring 3 with the corresponding diameter can be selected according to the circular axis of the anchor rod. That is, each specification of the fixing ring 3 matches the diameter of the bearing platform within a certain range, ensuring that the radial positioning reference of the fixing ring 3 perfectly matches the design boundary of the bearing platform. When the second end of the indicator rod 5 abuts against the top of the fixing ring 3, the marked anchor rod position is exactly within the design radial range of the bearing platform, avoiding problems such as the anchor rod colliding with the reinforcing steel too close or exceeding the stress zone due to deviations in the specifications of the fixing ring 3.

[0036] In a feasible embodiment of this utility model, a first connecting cylinder 8 is provided on the side of each arc segment near the support 1, and multiple second connecting cylinders 9 are provided on the outer periphery of the support 1. One end of the connecting rod 4 is connected to the first connecting cylinder 8, and the other end of the connecting rod 4 is connected to the second connecting cylinder 9. The first connecting cylinder 8 and the arc segment, and the second connecting cylinder 9 and the support 1 are all pre-welded or integrally formed, and their circumferential direction strictly points to the center of the bearing platform. Both ends of the connecting rod 4 can be directly inserted into the first connecting cylinder 8 and the second connecting cylinder 9. The inner walls of the first connecting cylinder 8 and the second connecting cylinder 9 will form a radial constraint on the connecting rod 4, forcing the connecting rod 4 to be arranged along the radial direction of the support center and the arc segment, and avoiding the eccentricity of the fixing ring 3 due to the installation deviation of the connecting rod 4.

[0037] The coordinated design of the first connecting cylinder 8, the second connecting cylinder 9, and the connecting rod 4 not only solves the defects of insufficient rigidity, difficulty in controlling precision, and cumbersome disassembly and assembly in traditional connections, but also enhances the compatibility of arc segment splicing and multi-specification fixing rings 3 through standardized interfaces. Ultimately, it forms a system with precise positioning, flexible adaptation, and low-cost maintenance with components such as the support 1, indicator rod 5, and anchor rod 6, thereby improving the practicality and economy of the circular foundation anchor positioning device.

[0038] In one feasible embodiment of this utility model, the second connecting cylinders 9 are evenly distributed around the outer periphery of the support 1. The second connecting cylinders 9 are distributed at equal angles around the outer periphery of the support 1, and the tension of the connecting rods 4 from the support 1 to the fixing ring 3 is evenly distributed along the circular axis. This symmetrical tension can counteract lateral forces that may occur during construction, preventing the fixing ring 3 from shifting to one side due to insufficient tension on one side, and ensuring that the center of the fixing ring 3 strictly coincides with the center of the support 1. If a section of the arc-shaped segment experiences a slight shift due to unexpected force during construction, the evenly distributed second connecting cylinders 9 will transmit a reverse constraint through the corresponding connecting rods 4.

[0039] In one feasible embodiment of this utility model, the thickness of the connecting rod 4 is less than the thickness of the support 1 in the direction perpendicular to the ground. The smaller thickness of the connecting rod 4 creates a certain gap between the top plane of the support 1 and the top of the connecting rod 4, preventing interference between the indicator rod 5 and the connecting rod 4 during rotation.

[0040] In one feasible embodiment of this utility model, both the arc-shaped segment and the sleeve 2 are stainless steel pipes. The stainless steel pipe has a smooth surface, allowing any concrete slurry or mud adhering to it after construction to be directly washed away with a high-pressure water gun without the need for rust removal. Furthermore, the stainless steel pipe has a higher hardness than ordinary carbon steel and a smooth surface, resulting in minimal wear during repeated assembly and disassembly, preventing the wear from increasing the clearance between the parts.

[0041] The circular foundation anchor positioning device provided by this utility model is described below using a fixing ring 3 composed of four arc segments as an example. The installation steps are as follows: (1) Determine the center position of the foundation by setting out.

[0042] (2) Drill holes and embed anchor rods 6.

[0043] (3) Install a support 1 with an angle scale on the top of the anchor rod 6.

[0044] (4) Connect the four arc segments with sleeve 2 to form a fixed ring 3.

[0045] (5) Connect the fixing ring 3 and the support 1 with the connecting rod 4.

[0046] (6) Install a rotatable indicator rod 5 on the top of the support 1.

[0047] (7) Install a cap buckle 7 on the top of the rotatable indicator rod 5.

[0048] The usage process is as follows: (1) Assume that the plan is to have 10 anchor rods in a single ring, with an axial diameter of 1.5 meters for the anchor rod ring.

[0049] (2) After installation, select a fixing ring 3 with a diameter of 1.5 meters.

[0050] (3) Select the intersection of the tower center and the pier center on the anchor bolt ring axis as the first anchor bolt position.

[0051] (4) Based on the 10 anchor rods, the angle between every 2 anchor rods and the center of the foundation is 40 degrees. Based on the position of the first anchor rod, rotate the dial clockwise or counterclockwise by 40 degrees. The position of the fixing ring is the center position of the second anchor rod.

[0052] (5) Repeat this process to locate all anchor bolt positions.
