Description

Technical Field

[0001] The invention belongs to the technical field of bolster stone anchor hole detection, and in particular relates to a bridge support bolster stone anchor hole positioning detection device. Background Art

[0002] Bridge anchor holes are used to secure bearings and transfer loads. Their positioning accuracy directly impacts bearing installation and bridge safety. However, during construction, positioning deviations, concrete defects, and other factors can easily lead to hole position errors. Therefore, hole coordinates, depth, and other parameters must be inspected to ensure structural stability.

[0003] The anchor holes of the bridge support pedestal are used to fix the support and transfer the load. Before pouring and forming, it is usually necessary to inspect the position and verticality of the anchor holes reserved on the template. Concrete can only be poured after passing the inspection. However, during the concrete pouring process, the mold tube of the reserved anchor hole is prone to displacement deviation due to the effects of concrete pouring vibration, flow extrusion, etc. Therefore, before the pedestal is formed and the support is installed, the reserved anchor hole still needs to be fully inspected again, such as the device for detecting pre-buried holes of the support pedestal disclosed in patent announcement No. CN222773890U; however, when detecting the position of the anchor hole, due to the great difficulty in locating the center axis of the anchor hole, most inspections can only be based on the edge of the hole, which reduces the inspection accuracy to a certain extent. In addition, in order to ensure the measurement accuracy during inspection, the inspection device needs to be precisely docked with the anchor hole, but this operation requires precision, which affects the overall inspection efficiency.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

The conductive sheet 55 and the arc-shaped resistor bar 52 are electrically connected to the control box 2. When the conductive sheet 55 and one end of the arc-shaped resistor bar 52 move to the other end, the resistance of the connection circuit between the arc-shaped resistor bar 52 and the conductive sheet 55 changes synchronously.

[0035] The sliding block 6 is arranged on one side of the support column 1, and a strip hole 7 is opened on the end face of the cross plate 3, and the sliding block 6 is slidably set inside the strip hole 7. The hole wall of the strip hole 7 is installed with a distance detection component 8, and the distance detection component 8 is used to detect the position of the sliding block 6. The distance detection component 8 includes a mounting groove 81 opened in the hole wall of the strip hole 7, and a horizontal laser ranging probe 82 is fixedly installed in the groove of the mounting groove 81. A reflective block 83 is fixedly installed on the side wall of the sliding block 6 close to the horizontal laser ranging probe 82, and the horizontal laser ranging probe 82 is electrically connected to the control box 2. The horizontal laser ranging probe 82 can measure the distance between it and the reflective block 83 by emitting a laser beam and calculating the time required to receive the reflected laser beam.

[0036] The electric lifting rod 9 is fixedly inserted into the end face of the sliding block 6. An automatic positioning unit 10 is provided below the electric lifting rod 9. The automatic positioning unit 10 automatically aligns the position of the sliding block 6 based on the position of the anchor hole. The automatic positioning unit 10 includes a plurality of magnetic isolation blocks 101. Two adjacent magnetic isolation blocks 101 are fixedly connected by a cylinder. The side wall of each magnetic isolation block 101 is integrally formed with a plurality of protrusions 102, and each protrusion 102 is evenly distributed in a ring about the axis of the magnetic isolation block 101 on the same side. The protrusions 102 on the side walls of each magnetic isolation block 101 are staggered with each other, and each protrusion 102 and the side wall of the magnetic isolation block 101 on the same side are provided with a sliding groove 103. In addition, a T-shaped insulating magnetic isolation column 104 is slidably arranged inside each slide groove 103, and a magnetic push assembly 11 and a follow-up resistance adjustment assembly 12 are arranged between each T-shaped insulating magnetic isolation column 104 and the slide groove 103 on the same side.

An insulating ring 113 is fixedly installed at the notch of the slide groove 103, and a non-magnetic spring 114 is fixedly arranged between the insulating ring 113 and the T-shaped insulating magnetic isolation column 104, and the electromagnetic component 111 is electrically connected to the control box 2.

[0037] Each follow-up resistance adjustment component 12 includes a conductive sleeve 121 fixedly sleeved on the side wall of the T-shaped insulating magnetic isolation column 104, and a conductive ring 122 is fixedly installed on the inner wall of the insulating ring 113, and the inner ring wall of the conductive ring 122 is in sliding contact with the outer wall of the conductive sleeve 121. The conductive ring 122 and the conductive sleeve 121 are electrically connected to the control box 2. After the contact point position of the conductive ring 122 and the conductive sleeve 121 changes, the connection loop resistance of the conductive ring 122 and the conductive sleeve 121 will change synchronously.

[0038] The end of each T-shaped insulating magnetic isolation column 104 away from the magnetic isolation block 101 on the same side is fixedly connected to a positioning block 105, and the side wall of each positioning block 105 away from the magnetic isolation block 101 on the same side is rotatably connected to a ball 106. A bottoming feedback component 13 is installed between the movable end of the electric lifting rod 9 and the uppermost magnetic isolation block 101, and a depth positioning component 14 is provided at the movable end of the electric lifting rod 9. The design of the protrusions 102 on the side walls of each magnetic isolation block 101 are staggered to avoid the local loss of the anchor hole wall affecting the accuracy of automatic alignment.

[0039] The bottoming feedback component 13 includes a limit sleeve 131 arranged below the electric lifting rod 9, and the limit sleeve 131 is fixedly connected to the top of the magnetic isolation block 101 on the same side. A pressure sensor 132 and an elastic rubber sleeve 133 are installed between the bottom inner wall of the limit sleeve 131 and the movable end of the electric lifting rod 9, and the elastic rubber sleeve 133 is sleeved on the outside of the pressure sensor 132. The limit sleeve 131 is slidably sleeved on the outside of the movable end of the electric lifting rod 9. The pressure sensor 132 is electrically connected to the control box 2. After the pressure exceeds the threshold, the pressure sensor 132 can feedback an electrical signal to the control box 2.

[0040] The depth positioning assembly 14 includes a U-shaped frame 141 fixedly mounted on the bottom of the sliding block 6, and the movable end of the electric lifting rod 9 slides through the horizontal part of the U-shaped frame 141. The horizontal end face of the U-shaped frame 141 is fixedly plugged with a depth laser ranging probe 142. The movable end of the electric lifting rod 9 is fixedly sleeved with a reflective ring 143, and the reflective ring 143 is arranged below the depth laser ranging probe 142. The depth laser ranging probe 142 is electrically connected to the control box 2. The depth laser ranging probe 142 can measure the distance between itself and the reflective ring 143 by emitting a laser beam and calculating the time required to receive the reflected laser beam.

[0041] The end faces of the sliding block 6 are fixedly connected to support blocks 15 on both sides, and the end faces of the two support blocks 15 are fixedly plugged with locking electric push rods 16, and the movable ends of the two locking electric push rods 16 are fixedly connected to anti-sliding blocks 17. By locking the electric push rods 16 and the anti-sliding blocks 17, the position of the sliding block 6 can be locked and fixed.

[0042] The operating principle of the present invention is described as follows: the support column 1 is installed at the central axis of the pier (the central axis of the pier can be measured by a total station or other equipment, refer to Figure 9 , Figure 9(Figure 2 is a schematic diagram of the support column 1 installed on the bridge pier, with the dotted line portion being a schematic diagram of the bridge pier and pad stone). After the pad stone is cast and formed, the control box 2 is connected to the external power supply cable and then started. At the same time, the operator rotates the cross plate 3 and moves the sliding block 6 horizontally to the top of the anchor hole to be inspected. After the movement is completed, a detection command is sent to the control box 2 via the remote control. At this time, the control box 2 controls the electric lifting rod 9 to extend, and the electric lifting rod 9 can drive each magnetic isolation round block 101 to move downward and insert into the anchor hole. After the electric lifting rod 9 is extended 10 cm, the control box 2 controls the electric lifting rod 9 to stop working.

[0043] Subsequently, the control box 2 controls each electromagnetic component 111 to be energized and work. After the electromagnetic component 111 is energized, it will generate a magnetic repulsive force on the permanent magnet 112 on the same side, thereby pushing each permanent magnet 112 to drive each T-shaped insulating magnetic isolation column 104 to move away from the electromagnetic component 111. At this time, each positioning block 105 will move toward the wall of the anchor hole. When there is an offset between the magnetic isolation block 101 and the anchor hole, when some of the balls 106 come into contact with the wall of the anchor hole, the balls 106 on this side are blocked and cannot move. Therefore, the magnetic isolation block 101 will move in the opposite direction until Until all the balls 106 are in contact with the anchor holes, the magnetic isolation block 101 and the anchor holes can be kept coaxial. At the same time, when the magnetic isolation block 101 moves, the magnetic isolation block 101 will drive the sliding block 6 to move in the horizontal direction through the electric lifting rod 9, thereby adjusting the horizontal position of the sliding block 6 in the strip hole 7 and adjusting the angle of the cross plate 3. After the electromagnetic component 111 is energized for 10 seconds, the control box 2 will control the two locking electric push rods 16 to work for 2 seconds. At this time, the two anti-sliding blocks 17 will move down and abut against the cross plate 3, thereby locking the position of the sliding block 6.

[0044] Subsequently, the control box 2 controls the horizontal laser ranging probe 82 to work. The horizontal laser ranging probe 82 emits a laser beam. After the laser beam is reflected by the reflective block 83, the horizontal laser ranging probe 82 calculates the time required to receive the reflected laser beam to measure the horizontal displacement distance of the sliding block 6. At the same time, the control box 2 supplies power to the conductive sheet 55 and the arc-shaped resistor bar 52, and detects the current intensity of the circuit connecting the conductive sheet 55 and the arc-shaped resistor bar 52, and converts the current intensity into angle information (when the conductive sheet 55 and one end of the arc-shaped resistor bar 52 move to the other end, the arc-shaped resistor bar 52 is connected). The longer the length of the current inserted into the connection loop between the conductive sheet 55 and the control box 2, the greater the resistance of the connection loop. Thus, by detecting the current intensity of the connection loop between the conductive sheet 55 and the arc-shaped resistor strip 52, angle information can be fed back. By detecting the horizontal displacement distance and angle information of the sliding block 6 and comparing this horizontal displacement distance and angle information with the distance and angle between the preset anchor hole and the central axis of the pier, it is determined whether the anchor hole position is within the error range, thereby measuring the accuracy of the anchor hole position (the control box 2 will display the comparison result and the deviation distance).

[0045] When the anchor hole position is qualified, the control box 2 will control the electric lifting rod 9 to continue to move downward, and the electric lifting rod 9 will drive the magnetic isolation round block 101 to continue to move downward, so that each ball 106 moves downward along the hole wall of the anchor hole. When the ball 106 moves to the missing position of the anchor hole wall, the obstruction of the anchor hole wall on the ball 106 disappears, and the sliding block 6 is now locked by the electric push rod 16 and the anti-sliding block 17. Therefore, the ball 106 is fixed under the magnetic repulsion force of the electromagnetic part 111 on the same side. Under the action of the electric current detector 106, the ball 106 continues to move toward the missing part, so that the T-shaped insulating magnetic isolation column 104 drives the conductive sleeve 121 on the same side to extend further, and the control box 2 will detect the current intensity flowing through the connection loop between each conductive sleeve 121 and the conductive ring 122 on the same side in real time. When the extension distance of the conductive sleeve 121 increases, the length of the conductive sleeve 121 connected to the conductive ring 122 connection loop becomes longer. At this time, the resistance of the connection loop increases, so the current intensity flowing through becomes smaller. After the current intensity exceeds the threshold, the electric current intensity decreases. (This threshold is set based on the qualified requirements for the missing depth of the anchor hole wall, which is generally not greater than 2 cm. For missing positions greater than 2 cm, when the subsequent support anchor rod is inserted into the anchor hole for concrete pouring, the concrete may not be able to fully fill the missing position, resulting in a large cavity at the connection between the support anchor rod and the anchor hole, affecting the connection strength). The control box 2 will immediately control the electric lifting rod 9 to stop working and start the depth laser ranging probe 142. The depth laser ranging probe 142 has the same principle as the horizontal laser ranging probe 82. The depth laser ranging probe 142 will measure the displacement distance of the reflective ring 143. At the same time, the control box 2 will record the number of the conductive sleeve 121 where the defect position is detected and the distance information detected by the depth laser ranging probe 142 (each conductive sleeve 121 is numbered, such as A1, A2, A3, etc., to facilitate the location of the anchor hole defect). This will facilitate subsequent staff to repair the missing position and help improve the connection strength between the subsequent support and the anchor hole.

[0046] At the same time, when the anchor hole is skewed, the magnetic isolation block 101 maintains vertical movement under the action of the electric lifting rod 9. Therefore, when the anchor hole is skewed, the downward movement of the magnetic isolation block 101 will be blocked, and the conductive sleeve 121 on the blocked side will move toward the inside of the slide groove 103 along with the T-shaped insulating magnetic isolation column 104, while the conductive sleeve 121 on the other side will move outward because there is no hole wall of the anchor hole to block it. At the same time, since the vertical movement is blocked by the inclined hole wall of the anchor hole, the pressure sensor 132 will also detect that the pressure exceeds the threshold value. At this time, the control box 2 will issue a voice alarm to remind personnel that the anchor hole is skewed.

[0047] When the anchor hole is not skewed, when the magnetic isolation block 101 moves to the bottom of the anchor hole, the magnetic isolation block 101 cannot continue to move. At this time, the pressure sensor 132 will detect that the pressure exceeds the threshold. At this time, the control box 2 will control the electric lifting rod 9 to stop working and control the depth laser ranging probe 142 to work, so as to detect whether the hole depth of the anchor hole meets the use requirements. After the hole depth detection is completed, the control box 2 controls the electric lifting rod 9 to move back, so that the magnetic isolation block 101 moves back and resets from the anchor hole, and then the staff can start the detection of the next anchor hole.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
