Description

Technical Field

[0001] The invention relates to a high-slope anchor hole positioning device, which is suitable for high-slope anchor hole drilling, soil nail wall and other similar processes. Background Art

[0002] The high slope protection technology of anchor frame beam is an important form of protection for road cutting excavation. After the slope is brushed, it is difficult to accurately lay out the holes according to the designed longitudinal and transverse distances on the slope with a certain inclination angle, resulting in inaccurate layout and deviation of anchor holes. The deviation of anchor holes will directly affect the subsequent frame beam construction process: first, it causes the frame beam reinforcement binding line to be not straight, and the anchor is not in the node position reinforcement, affecting the quality of the project; second, it makes it impossible to install the fixed steel mold, resulting in the template line not straight, which in turn affects the appearance quality of the entire frame beam. The device has a simple structure, flexible operation, safety and reliability, and accurate layout. It is suitable for the layout of anchor holes in slopes with high slopes and large slopes. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a high slope anchor hole positioning device, which solves the problems of hole deviation and low layout efficiency caused by the traditional use of steel tape measure to directly lay out on the slope surface, and also eliminates the problems of subsequent frame beam reinforcement binding nodes not being at the anchor hole position due to hole deviation, template installation and node conflict. The device has a simple structure, flexible operation, safety and reliability, high hole layout efficiency, and is suitable for anchor hole layout in slopes with high slopes and large slopes.

[0004] The technical solution adopted by the present invention is:

[0005] A high slope anchor hole positioning device comprises a standard rod and a leg sleeve, wherein the leg sleeves are arranged at both ends of the standard rod, movable legs are movably arranged in the leg sleeves, and the movable legs are connected to the leg sleeves through a height adjustment device I, a protractor is arranged in the center of the standard rod, the diameter side of the protractor is parallel to the standard rod, a pointer is arranged on the protractor, and the pointer is connected to the protractor through a rotatable fixing device, a positioning sleeve is arranged on the pointer, a positioning leg is arranged in the positioning sleeve, and the positioning leg is connected to the positioning sleeve through a height adjustment device II.

[0006] Further preferably, an auxiliary leg is provided below the protractor, and the auxiliary leg is connected to the protractor via a screw lock.

[0007] Further preferably, the height adjustment device is a locking screw.

[0008] Further preferably, the rotatable fixing device is a locking screw.

[0009] It is further preferred that the height adjustment device II is a positioning locking screw. The height adjustment system consists of a leg sleeve, a movable leg, and a locking screw. The movable leg can be freely extended and retracted to adjust the standard rod to be flush with the slope line. The leg is supported on the slope to play a fixing role, thereby ensuring the initial positioning of the positioner is accurate.

[0010] The angle adjustment system consists of a protractor, a standard rod, a pointer, a positioning sleeve, and a locking screw. The positioning sleeve can rotate 180°, and the pointer can accurately point to the protractor scale. The sleeve is selected according to the designed angle between the anchor rod and the slope, and then the sleeve is fixed to determine the angle.

[0011] The positioning system consists of a positioning sleeve, movable positioning legs, and locking screws. The movable positioning legs can be freely extended and retracted. When the angle is determined and locked, the positioning movable legs extend toward the slope surface to accurately locate the anchor hole.

[0012] When the present invention is used:

[0013] 1. Use an excavator to brush the slope to ensure that the slope surface is basically flat and the slope ratio meets the design and specification requirements;

[0014] 2. Lay out the top and foot of the slope according to the design documents, and at the same time lay out the top and foot elevations and bring out the elevation lines. Then, use a steel tape measure to locate the top and foot of the slope according to the design spacing along the longitudinal direction of the slope along the horizontal elevation line, and insert the points with steel bars, and then bring out the slope lines for each design spacing.

[0015] 3. After the slope line of the entire slope is brought out, use a steel tape measure to place a point at each designed interval along the slope line and mark the position with tape;

[0016] 4. After the standard anchor points of the entire slope are released on the slope line, the next step is to use the anchor hole locator to place the points on the slope line onto the actual slope. The specific operations are as follows:

[0017] (1) Align the center point of the anchor hole locator protractor with the point on the slope line, and then adjust the height of the movable legs at both ends to make them coincide with the slope line.

[0018] (2) Rotate the positioning sleeve, use the pointer to accurately point to the designed angle between the anchor rod and the slope, and then tighten the screw to lock the angle.

[0019] (3) Adjust the retractable positioning legs and accurately position the positioning fingertips on the slope based on the locked angle.

[0020] The present invention provides a high slope anchor hole locator device, and the technical effects are as follows:

[0021] 1. Adjust the retractable legs on both sides of the standard pole to align the standard pole with the slope line and position the height.

[0022] 2. Rotate the positioning sleeve, use the pointer to accurately point to the designed angle between the anchor rod and the slope, and then tighten the screw to lock the angle.

[0023] 3. Adjust the retractable positioning legs and accurately position the positioning fingertips on the slope based on the locked angle.

[0024] 4. The highly retractable outriggers and angle-positioned retractable outriggers can realize stakeout on slopes of various slope ratios.

[0025] 5. According to the equally spaced hole positions, the anchor hole position locator can be used to efficiently and accurately lay out the anchor hole positions.

[0026] 6. It greatly improves the efficiency of anchor bolt layout on the slope, and at the same time improves the accuracy of angled anchor bolt hole positions, laying a solid foundation for subsequent frame beam reinforcement construction, template installation and other processes, ensuring the quality of the project entity, beautiful appearance, outstanding overall effect, and good application and promotion value.
