Description

Technical Field

[0001] This utility model belongs to the field of power construction technology, and specifically relates to a power tower anchor bolt measuring device. Background Technology

[0002] The main functions of anchor bolts for power towers include fixing the tower, transferring loads, and adjusting the tower height. Specifically, anchor bolts tightly connect the power tower to the foundation, ensuring the tower's stability under external factors such as wind and ice loads. Simultaneously, they transfer the load borne by the tower to the foundation, ensuring the safety of both the foundation and the tower. Furthermore, anchor bolts have an adjustment function, allowing the tower height to be adjusted according to terrain and construction requirements. Currently, anchor bolts are generally pre-cast into the foundation using concrete. To ensure the anchor bolts meet usage requirements, the exposed length of the anchor bolts is generally between 150mm and 200mm. Therefore, the exposed length of the anchor bolts should be measured before tower erection. The common measurement method is manual measurement using a measuring tape. However, because the anchor bolts are positioned low, many construction workers simply compare the measurement and estimate the reading, resulting in significant measurement errors. Utility Model Content

[0003] The purpose of this utility model is to provide a measuring device for anchor bolts of power towers.

[0004] This utility model is achieved through the following measures: a power tower anchor bolt measuring device, characterized in that it includes a fixed cylinder with a length greater than the length of the anchor bolt protruding from the foundation and a movable cylinder concentrically sleeved on the outside of the fixed cylinder, and the outer wall of the fixed cylinder is provided with a length measuring scale line along the axial direction, and the zero scale line of the scale line is flush with the lower end face of the fixed cylinder.

[0005] Inside the movable cylinder, there are concentric columns of the same length as the movable cylinder. The lower end face of the column is flush with the lower end face of the movable cylinder, and the upper end of the column is fixedly connected to the movable cylinder by several connecting rods.

[0006] Furthermore, the smallest graduation on the scale is generally 1 millimeter.

[0007] Furthermore, the length measurement scale lines are set in several sets and are evenly distributed circumferentially on the outer wall of the fixed cylinder.

[0008] Furthermore, there is a gap between the outer wall of the fixed cylinder and the inner wall of the movable cylinder, and a sealing ring is concentrically arranged in the gap. The sealing ring is located at the lower part of the gap and is in close contact with the inner wall of the movable cylinder and the outer wall of the fixed cylinder.

[0009] Furthermore, a limiting plate is fixedly provided on the upper end surface of the fixed cylinder to restrict the movable cylinder from detaching from the fixed cylinder.

[0010] Furthermore, a handle is fixedly provided on the outer wall of the movable cylinder.

[0011] Because the anchor bolts are embedded in the concrete foundation, concrete residue will remain where the bolts protrude from the top surface of the foundation, affecting measurement accuracy and subsequent nut installation. Furthermore, a fixed shaft concentric with the upper end of the column is fixedly installed. A horizontal rod is rotatably mounted on the fixed shaft via bearings. The outer end of the horizontal rod extends beyond the movable cylinder, and a movable rod is bolted to the protruding end. A base is hinged to the lower end of the movable rod, and a grinding disc is fixedly mounted on the lower end of the base. The grinding disc is typically bolted to the lower end of the base for easy disassembly and replacement.

[0012] Furthermore, the movable rod is a telescopic rod. The telescopic rod typically uses an inner and outer cylinder that are interlocked and then fixed together with bolts. The movable rod is equipped with a non-slip grip sleeve.

[0013] The grinding disc can be used to grind the contact surface between the anchor bolts and the foundation to keep it flat, which facilitates measurement and also allows for better fit with the foundation when installing the nuts.

[0014] How to use:

[0015] When grinding the contact surface between the foundation and the anchor bolts, place the grinding disc downwards and abut the column against the upper surface of the anchor bolts. Then, loosen the bolts securing the movable rod and adjust the position of the grinding disc to grind the contact surface between the foundation and the anchor bolts. The base for mounting the grinding disc is hinged for better contact with the foundation surface. Hold the movable cylinder with one hand and rotate the movable rod with the other. The movable rod can then grind along the outer edge of the anchor thread until the surface is smooth.

[0016] After grinding, turn the measuring device around so that the lower end of the fixed cylinder rests against the foundation. Then press the movable cylinder until the lower end of the column is flush with the upper end of the anchor bolt. Since the lower end of the column is flush with the lower end of the movable cylinder, the exposed length of the anchor bolt can be obtained by observing the position of the lower end of the movable cylinder corresponding to the scale line.

[0017] The position of the movable cylinder can be fixed by the friction between the sealing ring and the movable and fixed cylinders. When it needs to be reset, it needs to be manually reset.

[0018] The beneficial effects of the technical solution provided by this utility model embodiment are: the movable cylinder and the column can move along the movable cylinder, and the exposed length of the anchor bolt can be directly obtained through the contact between the column and the anchor bolt; since the axis of the fixed cylinder is parallel to the anchor bolt, the measurement error is small.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. Of course, the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit its scope.

[0028] Example 1:

[0029] See Figures 1-6 A power tower anchor bolt measuring device, characterized in that it includes a fixed cylinder 1 with a length greater than the length of the anchor bolt 13 protruding from the foundation 12 and a movable cylinder 2 concentrically sleeved on the outside of the fixed cylinder 1. The outer wall of the fixed cylinder 1 is provided with a length measuring scale line 5 along the axial direction, and the zero scale line 5 of the scale line 5 is flush with the lower end face of the fixed cylinder 1.

[0030] Inside the movable cylinder 2, there are concentric columns 3 of the same length as the movable cylinder 2. The lower end face of the column 3 is flush with the lower end face of the movable cylinder 2. The upper end of the column 3 is fixedly connected to the movable cylinder 2 by several connecting rods 4.

[0031] The smallest graduation on scale line 5 is generally 1 millimeter.

[0032] The length measurement scale lines 5 are set in several groups and are evenly distributed circumferentially on the outer wall of the fixed cylinder 1.

[0033] There is a gap between the outer wall of the fixed cylinder 1 and the inner wall of the movable cylinder 2. A sealing ring 6 is concentrically arranged in the gap. The sealing ring 6 is located at the lower part of the gap and is in close contact with the inner wall of the movable cylinder 2 and the outer wall of the fixed cylinder 1.

[0034] A limiting plate 7 is fixedly installed on the upper end surface of the fixed cylinder 1 to restrict the movable cylinder 2 from disengaging from the fixed cylinder 1.

[0035] A handle 201 is fixedly installed on the outer wall of the movable cylinder 2.

[0036] Because the anchor bolts 13 are pre-embedded in the concrete foundation 12, concrete residue will remain where the anchor bolts 13 protrude from the top surface of the foundation 12. This will affect the accuracy of measurements and the subsequent installation of nuts. A fixed shaft 301, concentric with the column 3, is fixedly installed on the upper end face of the column 3. A horizontal rod 8 is rotatably mounted on the fixed shaft 301 via a bearing 14. The outer end of the horizontal rod 8 extends beyond the movable cylinder 2, and a movable rod 9 is bolted to the protruding end. A base 10 is hinged to the lower end of the movable rod 9, and a grinding disc 11 is fixedly mounted on the lower end of the base 10. The horizontal rod 8 is generally fixed to the outer ring of the bearing 14 via a retaining ring 801.

[0037] The grinding disc 11 is usually fixed to the lower end of the base 10 with bolts, which facilitates disassembly and replacement later.

[0038] The movable rod 9 is a telescopic rod. Telescopic rods typically use an inner and outer cylinder that are interlocked and then fixed together with bolts. The movable rod 9 is equipped with a non-slip grip sleeve 901.

[0039] The grinding disc 11 can be used to grind the contact surface between the anchor bolt 13 and the foundation 12 to keep it flat, which facilitates measurement and also allows for better fit with the foundation 12 when installing the nut.

[0040] How to use:

[0041] When grinding is required on the contact surface between the foundation 12 and the anchor bolt 13, place the grinding disc 11 downwards and simultaneously press the column 3 against the upper surface of the anchor bolt 13. Then, loosen the bolts of the mounting rod 9 and adjust the position of the grinding disc 11 so that it can grind the contact surface between the foundation 12 and the anchor bolt 13. The base 10 for mounting the grinding disc 11 is hinged, which allows for better contact with the surface of the foundation 12. Hold the movable cylinder 2 with one hand and rotate the movable rod 9 with the other. At this time, the movable rod 9 can grind along the outer edge of the anchor thread until the surface is flat.

[0042] After grinding is completed, turn the measuring device around so that the lower end face of the fixed cylinder 1 is against the foundation 12. Then press the movable cylinder 2 until the lower end face of the column 3 is flush with the upper end face of the anchor bolt 13. Since the lower end face of the column 3 is flush with the lower end face of the movable cylinder 2, the exposed length of the anchor bolt 13 can be obtained by looking at the position of the lower end face of the movable cylinder 2 corresponding to the scale line 5.

[0043] The position of the movable cylinder 2 can be fixed by the friction between the sealing ring 6 and the movable cylinder 2 and the fixed cylinder 1. When it needs to be reset, it needs to be manually reset.

[0044] Example 2:

[0045] See Figures 1-2 A power tower anchor bolt measuring device, characterized in that it includes a fixed cylinder 1 with a length greater than the length of the anchor bolt 13 protruding from the foundation 12 and a movable cylinder 2 concentrically sleeved on the outside of the fixed cylinder 1. The outer wall of the fixed cylinder 1 is provided with a length measuring scale line 5 along the axial direction, and the zero scale line 5 of the scale line 5 is flush with the lower end face of the fixed cylinder 1.

[0046] Inside the movable cylinder 2, there are concentric columns 3 of the same length as the movable cylinder 2. The lower end face of the column 3 is flush with the lower end face of the movable cylinder 2. The upper end of the column 3 is fixedly connected to the movable cylinder 2 by several connecting rods 4.

[0047] The smallest graduation on scale line 5 is generally 1 millimeter.

[0048] The length measurement scale lines 5 are set in several groups and are evenly distributed circumferentially on the outer wall of the fixed cylinder 1.

[0049] There is a gap between the outer wall of the fixed cylinder 1 and the inner wall of the movable cylinder 2. A sealing ring 6 is concentrically arranged in the gap. The sealing ring 6 is located at the lower part of the gap and is in close contact with the inner wall of the movable cylinder 2 and the outer wall of the fixed cylinder 1.

[0050] A limiting plate 7 is fixedly installed on the upper end surface of the fixed cylinder 1 to restrict the movable cylinder 2 from disengaging from the fixed cylinder 1.

[0051] A handle 201 is fixedly installed on the outer wall of the movable cylinder 2.

[0052] How to use:

[0053] Place the lower end face of the fixed cylinder 1 against the foundation 12, then press the movable cylinder 2 until the lower end face of the column 3 is flush with the upper end face of the anchor bolt 13. Since the lower end face of the column 3 is flush with the lower end face of the movable cylinder 2, the exposed length of the anchor bolt 13 can be obtained by observing the position of the lower end face of the movable cylinder 2 corresponding to the scale line 5. The position of the movable cylinder 2 can be fixed by the friction between the sealing ring 6 and the movable cylinder 2 and the fixed cylinder 1. When resetting is required, manual resetting is necessary.
