Description

Technical Field

[0001] The invention belongs to the technical field of concrete anti-seepage panel cracking early warning, in particular to a concrete anti-seepage panel cracking early warning device. Background Art

[0002] During the construction of subway stations, it is necessary to lay asphalt concrete anti-seepage panels around the subway stations. Asphalt concrete anti-seepage panels are a kind of anti-seepage technology widely used in water conservancy projects and civil engineering projects. They can effectively prevent ground water from penetrating into the subway stations. Asphalt concrete anti-seepage panels have cracks that affect the appearance of the panels. More importantly, they will reduce the functionality of the anti-seepage panels and cause water penetration, which may affect the stability and safety of the entire earth-rock dam or water conservancy project. Therefore, asphalt concrete anti-seepage panel crack detection is an indispensable part of the production process.

[0003] The patent with publication number CN215728164U discloses an on-site asphalt concrete anti-seepage panel cracking early warning device, including a mobile base plate, a flaw detector and a battery. The flaw detector consists of an operating part and a plurality of detection parts. Two groups of vertical plates are fixedly installed on the mobile base plate. The upper ends of the two groups of vertical plates are fixedly connected to the horizontal plate. A detection rod is movably installed between the two groups of vertical plates. The detection rod is screwed to a threaded rod. A plurality of detection parts are distributed on the detection rod. The detection rod is raised and lowered by rotating the threaded rod, so that the distance of the detection part relative to the asphalt concrete anti-seepage panel can be adjusted, and then the height of the detection part can be accurately adjusted according to different road conditions on the surface of the on-site panel, thereby improving the practicality of the device. Secondly, it can detect cracks inside the concrete in time, which is convenient for providing early warning for component damage.

[0004] In the above scheme, the length of the detection rod is greater than the width of the movable bottom plate, so that a plurality of detection parts can be arranged, increasing the area detected by the plurality of detection parts at one time. However, such a design makes the entire device larger in size, which is inconvenient for the staff to store the device. Secondly, when the detection parts are stored, the detection parts distributed on both sides of the movable bottom plate lose the protection of the movable bottom plate, which can easily cause the detection parts to be damaged. For this reason, the present invention provides a concrete anti-seepage panel cracking early warning device. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a concrete anti-seepage panel cracking early warning device described in the present invention comprises a mobile base, two groups of handles are symmetrically installed on one end of the mobile base, a support frame is fixedly installed between the two groups of handles, a flaw detector operating part is fixedly installed on the support frame, a storage box is fixedly installed on the other end of the mobile base, a detection component for installing a flaw detector detection part is arranged in the storage box, the detection component comprises a main board, the main board is located in the storage box, a screw rod is screwed to the middle of the main board, the upper end of the screw rod is rotatably connected to the storage box, folding plates are arranged at both ends of the main board, two groups of flaw detector detection parts are fixedly installed on the lower end surfaces of the main board and the folding plate, both sides of one end of the folding plate are connected with a rotating shaft, the rotating shaft is rotatably connected to the side plate, the side plate is fixedly connected to the end of the main board, two groups of worm gears, the two groups of worm gears are fixedly mounted on the ends of the two groups of rotating shafts, the two groups of rotating shafts are meshed with worms, the worms are rotatably connected to the two groups of side plates, two groups of first guide grooves are symmetrically arranged on both sides of the storage box, and the side plates are slidably connected to the first guide grooves;

[0007] By folding the detection component and storing it inside the storage box, the detection part of the flaw detector can be stored in the storage box to avoid damage to the detection part of the flaw detector during transportation. Secondly, the volume of the folded detection component is reduced, thereby reducing the space occupied by the entire device, making it easier for staff to carry and store the device.

[0008] Preferably, the folding plate includes an active plate, two sets of rotating shafts are respectively connected to the two sides of one end of the main plate, and the driven plate of the active plate is movably plugged in, and the lower end surface of the driven plate is fixedly connected to the detection part of the flaw detector, a cross-scissor type telescopic frame is arranged between the active plate and the driven plate, a group of nodes of the cross-scissor type telescopic frame are rotated to the movable block, and the lower end surface of the movable block is fixedly connected to the detection part of the flaw detector, a spring is arranged on one side of the movable block, a receiving frame sleeved on the cross-scissor type telescopic frame, the receiving frame is rotated to another group of nodes on the cross-scissor type telescopic frame, the head end node of the cross-scissor type telescopic frame is plugged in and fixedly installed in the driven plate, the head end node of the cross-scissor type telescopic frame is rotatably connected to the bracket in the active plate, a second guide groove is provided on the lower end surface of the driven plate, sliding grooves are provided on both sides of the movable block, the sliding grooves are slidably connected to the groove edges of the second guide grooves, rollers are rotatably installed at both ends of the receiving frame, a countersunk groove is provided on one side of the side plate, the roller is located in the countersunk groove, and the countersunk groove includes a first arc surface, an inclined surface, and a second arc surface;

[0009] Since the length of the folding plate is shortened before it enters the storage box, the volume of the entire detection assembly is further reduced, which not only facilitates the staff's transportation and storage of the device, but also the shortened length of the folding plate can reduce the volume of the storage box accordingly, thereby reducing the production cost of the storage box.

[0010] Preferably, a limiting component is embedded and installed on the other side of the side plate, the limiting component includes a special-shaped wheel, a mounting groove is opened on the other side of the side plate, the rotating shaft passes through the mounting groove, and the special-shaped wheel is fixedly installed on the rotating shaft, a clamping plate clamping the special-shaped wheel, a movable head fixedly connected to the clamping plate, a U-shaped elastic bar sleeved on the movable head, a movable groove is opened on one side of the mounting groove, the clamping plate is slidably connected to the movable groove, the movable head and the U-shaped elastic bar are both located in the movable groove, and a limiting strip for limiting the movable head is arranged on one side of the first guide groove, and the limiting strip is composed of a first plate strip and a second plate strip;

[0011] When the flaw detector detection part descends to the best position for detecting the concrete anti-seepage panel, the movable head also descends with the side panel, and the movable head faces the second slat. At this time, there is no gap between the movable head and the second slat, so that the movable head cannot move, and the swivel shaft cannot rotate, so that the staff cannot fold and store the folding plate before returning it to the original position, avoiding damage to the two sets of flaw detector detection parts on the main board.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. By folding the detection component and storing it inside the storage box, the detection part of the flaw detector can be stored in the storage box to avoid damage to the detection part of the flaw detector during transportation. Secondly, the volume of the folded detection component is reduced, thereby reducing the space occupied by the entire device, which is convenient for staff to carry and store the device.

[0014] 2. The moving receiving frame drives the cross-scissors type telescopic frame to shorten the length of the cross-scissors type telescopic frame, and then the cross-scissors type telescopic frame drives the driven plate to slide toward the inside of the main board through the fixed shaft. At the same time, the cross-scissors type telescopic frame drives the movable block to slide along the second guide groove, and the movable block compresses the spring to make the flaw detector detection part on the movable block move toward the direction of the rotation axis. The length of the entire folding plate begins to shrink until the roller rolls to the intersection of the inclined surface and the second arc surface. At this time, the entire folding plate has not entered the storage box. As the folding plate continues to rotate, the roller rolls along the second arc surface, and the length of the folding plate does not change until the folding plate rotates into the storage box. Since the length of the folding plate is shortened before the folding plate enters the storage box, the volume of the entire detection assembly is further reduced, which not only further facilitates the staff to carry and store the device, but also the folding plate with a shorter length can reduce the volume of the storage box accordingly, thereby reducing the production cost of the storage box.

[0015] 3. When the detection parts of the two sets of flaw detectors are in the initial position, the movable head is facing the first slat on the limit strip, and there is a gap between the movable head and the first slat. When the folding plate is folded and stored, the special-shaped wheel will rotate with the rotating shaft, and at the same time, the tooth groove on the special-shaped wheel will squeeze the card plate, so that the card plate and the movable head move toward the first slat, and the card plate compresses the U-shaped elastic strip, so that the rotating shaft can rotate normally. When the detection part of the flaw detector descends to the best position for detecting the concrete anti-seepage panel, the movable head also descends with the side plate, and the movable head is facing the second slat. At this time, there is no gap between the movable head and the second slat, so that the movable head cannot move. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0026] Embodiment 1

[0027] like Figure 1 and Figure 2 As shown, a concrete anti-seepage panel cracking early warning device described in an embodiment of the present invention comprises a mobile base 1, two sets of handles 2 are symmetrically installed on one end of the mobile base 1, a support frame 3 is fixedly installed between the two sets of handles 2, a flaw detector operating part 4 is fixedly installed on the support frame 3, a storage box 5 is fixedly installed on the other end of the mobile base 1, a detection component 6 for installing a flaw detector detection part 7 is arranged in the storage box 5, the detection component 6 comprises a main board 601, the main board 601 is located in the storage box 5, a screw 602 is screwed to the middle of the main board 601, the upper end of the screw 602 is rotatably connected to the storage box 5, and both ends of the main board 601 are arranged There is a folding plate 603, and two groups of flaw detector detection parts 7 are fixedly installed on the lower end surfaces of the main board 601 and the folding plate 603. Both sides of one end of the folding plate 603 are connected with a rotating shaft 604, the rotating shaft 604 is rotatably connected to the side plate 605, and the side plate 605 is fixedly connected to the end of the main board 601, two groups of worm gears 606, and the two groups of worm gears 606 are respectively fixedly mounted on the ends of the two groups of rotating shafts 604, and the two groups of rotating shafts 604 are engaged with worm 607, and the worm 607 is rotatably connected to the two groups of side plates 605, and two groups of first guide grooves 501 are symmetrically opened on both sides of the storage box 5, and the side plates 605 are slidably connected to the first guide grooves 501.

[0028] Specifically, an avoidance groove 101 is provided on the mobile base 1, and the avoidance groove 101 is located directly below the main board 601. In the initial state, the two groups of flaw detector detection parts 7 installed on the main board 601 are located above the avoidance groove 101. During the construction of the subway station, when it is necessary to detect cracks in the concrete anti-seepage panel, the device is moved to the concrete anti-seepage panel by pushing the handle 2, and then the screw 602 is rotated to move the main board 601 together with the two groups of folding plates 603 and several groups of flaw detector detection parts 7 downward. During this process, the two groups of flaw detector detection parts 7 installed on the main board 601 pass through the avoidance groove 101 and continuously approach the concrete anti-seepage panel until the flaw detector detection part 7 drops to the best position for detecting the concrete anti-seepage panel, and then the flaw detector detection part 7 is operated by operating the flaw detector operating part 4. When the crack detection of the concrete anti-seepage panel is completed, the screw 602 is rotated again to return the main board 601, the folding plate 603 and the flaw detector detection part 7 to the initial position, and then the worm 607 is rotated, and the worm gear 606 will drive the rotating shaft 604 and the folding plate 603 to rotate upward, so that the folding plate 603 drives the corresponding flaw detector detection part 7 to rotate into the storage box 5, thereby realizing the folding and storage of the detection component 6. Compared with the prior art, the flaw detector detection part 7 is stored in the storage box 5 by folding the detection component 6, so as to avoid the flaw detector detection part 7 from being damaged during transportation. Secondly, the volume of the folded detection component 6 is reduced, thereby reducing the space occupied by the entire device, which is convenient for the staff to carry and store the device.

[0029] Embodiment 2

[0030] like Figures 3 to 5As shown, compared with Example 1, another implementation of the present invention is: the folding plate 603 includes an active plate 6031, two sets of rotating shafts 604 are respectively connected on both sides of one end of the main plate 601, a driven plate 6032 is movably plugged into the active plate 6031, and the lower end surface of the driven plate 6032 is fixedly connected to the flaw detector detection part 7, and a cross-shear type telescopic frame 6033 is arranged between the active plate 6031 and the driven plate 6032. A group of nodes of the cross-shear type telescopic frame 6033 are rotated to a movable block 6034, and the lower end surface of the movable block 6034 is fixedly connected to the flaw detector detection part 7, and a spring 6035 is arranged on one side of the movable block 6034, and a receiving frame 6036 is sleeved on the cross-shear type telescopic frame 6033. The receiving frame 6036 is rotated to the cross Another group of nodes on the scissors-type telescopic frame 6033, the head end node of the cross-scissors-type telescopic frame 6033 is plugged and fixedly installed on the fixed shaft 31 in the driven plate 6032, the head end node of the cross-scissors-type telescopic frame 6033 is rotatably connected to the bracket 32 ​​in the active plate 6031, a second guide groove 311 is opened on the lower end surface of the driven plate 6032, and sliding grooves 341 are opened on both sides of the movable block 6034. The sliding grooves 341 are slidably connected to the groove edges of the second guide grooves 311, and rollers 361 are rotatably installed at both ends of the receiving frame 6036. A countersunk groove 6051 is opened on one side of the side plate 605, and the roller 361 is located in the countersunk groove 6051. The countersunk groove 6051 includes a first arc surface 511, an inclined surface 512, and a second arc surface 513.

[0031] Specifically, in the initial state, the roller 361 is located at the intersection of the first arc surface 511 and the inclined surface 512. When the folding plate 603 drives the corresponding flaw detector detection part 7 to rotate toward the storage box 5, the folding plate 603 drives the two groups of rollers 361 to rotate together through the receiving frame 6036. As the receiving frame 6036 rotates, the roller 361 is squeezed by the inclined surface 512, and the roller 361 rolls along the inclined surface 512. At the same time, the roller 361 drives the receiving frame 6036 to move toward the direction of the rotating shaft 604. The moving receiving frame 6036 drives the cross-scissor type telescopic frame 6033 to shorten the length of the cross-scissor type telescopic frame 6033. Then, the cross-scissor type telescopic frame 6033 drives the driven plate 6032 to slide toward the inside of the main board 601 through the fixed shaft 31. At the same time, the cross-scissor type telescopic frame 6033 drives the movable block 6034 to slide along the second guide groove 311 , and the movable block 6034 compresses the spring 6035, so that the flaw detector detection part 7 on the movable block 6034 moves toward the direction of the rotating shaft 604, and the length of the entire folding plate 603 begins to shrink until the roller 361 rolls to the intersection of the inclined surface 512 and the second curved surface 513. At this time, the entire folding plate 603 has not entered the storage box 5. As the folding plate 603 continues to rotate, the roller 361 rolls along the second curved surface 513, and the length of the folding plate 603 does not change until the folding plate 603 rotates into the storage box 5. Since the length of the folding plate 603 is reduced before the folding plate 603 enters the storage box 5, the volume of the entire detection assembly 6 is further reduced, which not only further facilitates the staff to carry and store the device, but also the folding plate 603 with a smaller length can reduce the volume of the storage box 5 accordingly, thereby reducing the manufacturing cost of the storage box 5.

[0032] like Figure 6 and Figure 7 As shown, a limiting component 608 is embedded and installed on the other side of the side plate 605, and the limiting component 608 includes a special-shaped wheel 6081, a mounting groove 6052 is opened on the other side of the side plate 605, the rotating shaft 604 passes through the mounting groove 6052, and the special-shaped wheel 6081 is fixedly installed on the rotating shaft 604, a clamping plate 6082 clamped to the special-shaped wheel 6081, a movable head 6083 fixedly connected to the clamping plate 6082, and a U-shaped elastic strip 6084 sleeved on the movable head 6083, a movable groove 6053 is opened on one side of the mounting groove 6052, the clamping plate 6082 is slidably connected to the movable groove 6053, the movable head 6083 and the U-shaped elastic strip 6084 are both located in the movable groove 6053, and a limiting strip 502 for limiting the movable head 6083 is set on one side of the first guide groove 501, and the limiting strip 502 consists of a first plate strip 21 and a second plate strip 22.

[0033] Specifically, before the folding plate 603 is folded and stored, the main board 601, the folding plate 603, and the flaw detector detection part 7 need to be returned to the initial position. If the staff forgets to perform the return operation and folds the folding plate 603 for storage, the flaw detector detection part 7 on the folding plate 603 will be stored in the storage box 5, but the two groups of flaw detector detection parts 7 on the main board 601 are still placed outside the storage box 5. During the transportation of the device, it is easy to cause damage to the two groups of flaw detector detection parts 7 on the main board 601. Therefore, when the two groups of flaw detector detection parts 7 are in the initial position, the movable head 6083 is opposite to the first slat 21 on the limit strip 502, and there is a gap between the movable head 6083 and the first slat 21. When the folding plate 603 is folded and stored, the special-shaped wheel 6081 will rotate along with the rotation. The shaft 604 rotates together, and at the same time, the tooth groove on the special-shaped wheel 6081 squeezes the card plate 6082, so that the card plate 6082 and the movable head 6083 move toward the first slat 21, and the card plate 6082 compresses the U-shaped elastic strip 6084, so that the rotating shaft 604 can rotate normally. When the flaw detector detection part 7 descends to the best position for detecting the concrete anti-seepage panel, the movable head 6083 also descends with the side plate 605, and the movable head 6083 faces the second slat 22. At this time, there is no gap between the movable head 6083 and the second slat 22, so that the movable head 6083 cannot move, and the rotating shaft 604 cannot rotate, so that the staff cannot fold and store the folding plate 603 before the return operation, avoiding damage to the two sets of flaw detector detection parts 7 on the main board 601.

[0034] Working principle: Push the handle 2 to move the device to the concrete anti-seepage panel, then rotate the screw 602 to move the main board 601 together with the two sets of folding plates 603 and several sets of flaw detector detection parts 7 downward. During this process, the two sets of flaw detector detection parts 7 installed on the main board 601 pass through the avoidance groove 101 and continue to approach the concrete anti-seepage panel until the flaw detector detection part 7 drops to the best position for detecting the concrete anti-seepage panel, then operate the flaw detector detection part 7 by operating the flaw detector operating part 4, and then use the flaw detector detection part 7 to move downward. When the flaw detector detection part 7 is used for flaw detection, the pushing device moves, and the motion trajectory is the detection range. After the crack detection of the concrete anti-seepage panel is completed, the screw rod 602 is rotated again to return the main board 601, the folding plate 603, and the flaw detector detection part 7 to the initial position, and then the worm 607 is rotated, and the worm gear 606 will drive the rotary shaft 604 and the folding plate 603 to rotate upward, so that the folding plate 603 drives the corresponding flaw detector detection part 7 to rotate into the storage box 5, so as to realize the folding and storage of the detection component 6;

[0035] When the folding plate 603 drives the corresponding flaw detector detection part 7 to rotate toward the storage box 5, the folding plate 603 drives the two sets of rollers 361 to rotate together through the receiving frame 6036. As the receiving frame 6036 rotates, the rollers 361 are squeezed by the inclined surface 512, and the rollers 361 roll along the inclined surface 512. At the same time, the rollers 361 drive the receiving frame 6036 to move toward the direction of the rotating shaft 604. The moving receiving frame 6036 drives the cross-scissor type telescopic frame 6033 to shorten the length of the cross-scissor type telescopic frame 6033. Then, the cross-scissor type telescopic frame 6033 drives the driven plate 6032 toward the main board 601 through the fixed shaft 31. The movable block 6034 slides, and at the same time, the cross-scissor telescopic frame 6033 drives the movable block 6034 to slide along the second guide groove 311, and the movable block 6034 compresses the spring 6035, so that the flaw detector detection part 7 on the movable block 6034 moves toward the direction of the rotating shaft 604, and the length of the entire folding plate 603 begins to shrink until the roller 361 rolls to the intersection of the inclined surface 512 and the second curved surface 513. At this time, the entire folding plate 603 has not entered the storage box 5. As the folding plate 603 continues to rotate, the roller 361 rolls along the second curved surface 513, and the length of the folding plate 603 does not change until the folding plate 603 rotates into the storage box 5;

[0036] When the two sets of flaw detector detection parts 7 are in the initial position, the movable head 6083 is opposite to the first slat 21 on the limit strip 502, and there is a gap between the movable head 6083 and the first slat 21. When the folding plate 603 is folded and stored, the special-shaped wheel 6081 will rotate together with the rotating shaft 604. At the same time, the tooth groove on the special-shaped wheel 6081 will squeeze the clamping plate 6082, so that the clamping plate 6082 and the movable head 6083 move toward the first slat 21, and the clamping plate 6082 compresses the U-shaped elastic strip 6084, so that the rotating shaft 604 can rotate normally. When the flaw detector detection part 7 descends to the best position for detecting the concrete anti-seepage panel, the movable head 6083 also descends together with the side plate 605, and the movable head 6083 is opposite to the second slat 22. At this time, there is no gap between the movable head 6083 and the second slat 22, so that the movable head 6083 cannot move.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
