Description

Technical Field

[0001] The invention belongs to the field of concrete testing equipment, and in particular relates to a concrete testing device. Background Art

[0002] In the construction of various construction projects, concrete is the main building material, and its quality directly affects the stability and durability of the entire project. The strength of concrete is one of the important indicators to measure its quality, and is closely related to the safety, reliability and economy of the project. Through concrete testing, the quality, strength and construction effect of concrete can be comprehensively evaluated to ensure the quality and safety of the project. During the testing process, problems with concrete can be discovered in a timely manner, and corresponding measures can be taken to repair and improve them to avoid potential safety hazards.

[0003] Therefore, the testing of concrete can be carried out according to the provisions of the Standard Test Method for Performance of Ordinary Concrete Mixtures GB / T50080-2002. The consistency of concrete is generally tested through the slump and slump extension method. The current slump extension method is generally operated manually during use. However, the biggest problem encountered in manual operation is that it cannot guarantee that each test is objective and unified. For example, the mixing process is not uniform enough, and the slump cone is not vertical enough when it is lifted up. Each operation may affect the final test effect. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a concrete detection device, which forms a slump cylinder by abutting two groups of slump half cylinders against each other, and fills the slump cylinder in batches with a feeding cylinder at a speed of one-third of the filling each time, and extends a mixing stick into the slump cylinder to mix up and down and insert and tamp in a spiral direction from the outside to the center. After the slump cylinder is filled, the slump cylinder is lifted vertically. The slump expansion degree achieved by the equipment is more objective, and the result will be more referenceable.

[0010] The collapse assembly includes a transverse member, a vertical member, a third cylinder and a collapse half-cylinder, the transverse member is movably connected to the frame, the third cylinder is arranged at the lower end of the transverse member, the output end of the third cylinder is connected to the vertical member, and the collapse half-cylinder is movably connected to the vertical member; the collapse assembly includes two groups, the two groups of collapse assemblies are relatively arranged with the first motor as the symmetry center, the two groups of collapse half-cylinders are mutually abutted to form a truncated cone-shaped collapse cylinder with a hollow interior and penetrating from top to bottom, the bottom of the collapse cylinder can be abutted and connected to the lifting plate, the upper end opening of the collapse cylinder points to the rotating disk, and the lower end of the mixing rod extends into the collapse cylinder and not in contact with the collapse cylinder; the transverse movement component includes a fifth cylinder, a transverse movement seat and a second guide rail, the second guide rail is arranged on the cross bar, the transverse movement seat is cooperatively connected to the second guide rail, the fifth cylinder is connected to the barrel cover, the output end of the fifth cylinder is connected to the transverse movement seat, and the third cylinder is arranged at the lower end of the transverse movement seat; the vertical movement component includes a vertical movement plate, a sixth cylinder, a vertical movement seat and a third guide rail, the third guide rail is arranged on the vertical movement plate, the vertical movement seat is cooperatively connected to the third guide rail, the sixth cylinder is connected to the vertical movement plate, the output end of the sixth cylinder is connected to the vertical movement seat, and the collapse half cylinder is connected to the vertical movement seat through a connecting rod.

[0011] The scanning assembly includes a collection plate and a launch plate, which are respectively arranged on the left and right sides of the lifting plate, parallel to each other and perpendicular to the lifting plate, and a plurality of array-distributed probes are arranged on the launch plate, and a plurality of the probes are vertically pointed to the collection plate; a touch switch is arranged on the lifting plate, the touch switch is abutted against the collapsed half cylinder, and the touch switch is electrically connected to the launch plate.

[0012] In order for the concrete detection device using this structure to detect and calculate the slump expansion, two conditions must first be met. One is that after the collapse cylinder is filled with concrete, a mixing rod can be inserted into the cylinder to mix it up and down and to insert and tamp it in a spiral direction from the outside to the center so that the concrete can completely fill the entire space of the collapse cylinder. The other is that after the collapse cylinder is filled, the collapse cylinder must be lifted vertically upward.

[0013] Therefore, in order to enable the mixing rod to mix up and down in the collapse cylinder, it is necessary to be able to move up and down. Therefore, two groups of parallel and non-contacting cross bars are placed horizontally at the upper end of the frame composed of the side frame and the bottom plate. Hoops are provided on the cross bars. The circular structure formed by the two groups of hoops encloses the barrel body and fixes the barrel body. The upper opening of the barrel body is covered with a barrel cover, and the second cylinder is connected to the barrel cover. The output end of the second cylinder extends into the inner cavity of the barrel body, and the first motor is connected to the output end of the second cylinder. The output end of the first motor is connected to the center of the rotating disk, and the rotating groove in the notch of the edge of the rotating disk cooperates with the plug-in column of the sleeve on the outer wall of the mixing stick. Therefore, when the second cylinder is driven, the mixing stick can move up and down, and when the first motor is driven, the mixing stick It will rotate with the rotating disk as the center of rotation, so the mixing stick can also rotate in the spiral direction, but it still cannot move from the outside to the center. Therefore, a rotating seat is set on the rotating disk, and the rotating seat can be rotatably connected to the fourth cylinder. The output end of the fourth cylinder can be rotatably connected to the rotating column on the sleeve. Therefore, during the pushing of the fourth cylinder, the upper end of the mixing stick will move outward, causing the lower end of the mixing stick to rotate in the opposite direction. The farther it is pushed, the greater the inclination angle of the lower end of the mixing stick. Therefore, the inclination angle of the lower end of the mixing stick can be changed during the retraction of the fourth cylinder. Therefore, when the second cylinder, the first motor and the fourth cylinder are linked, the mixing stick can be inserted into the collapse cylinder to achieve up and down mixing and insertion from the outside to the center in the spiral direction.

[0014] In order to fill the collapse cylinder with concrete, a feeding cylinder is arranged on the barrel body, and the opening at the lower end of the feeding cylinder points to the extension hole, and the lower end of the extension hole is exactly the collapse cylinder. Therefore, concrete can be filled into the collapse cylinder by putting it in the feeding cylinder. If necessary, a quantitative divider can be arranged at the opening at the lower end of the feeding cylinder, so that concrete can be placed in the collapse cylinder in a quantitative manner, thereby achieving the standard requirement of adding one-third of the height of the collapse cylinder before each mixing. Since the quantitative divider is a relatively conventional existing technology, it will not be elaborated here.

[0015] As the mixing rod is mixing up and down in the collapse cone, it needs to gradually rise and eventually leave the area where the collapse cone is located. Therefore, the collapse cone needs to be fixed on the lifting plate while the lifting plate must be able to move up and down. Therefore, the lifting plate and the bottom plate are connected by a first cylinder, and the lifting plate is moved up and down by driving the first cylinder. The lifting plate cooperates with the first slide rail to keep the lifting plate moving up and down smoothly.

[0016] After the concrete filling in the collapse cylinder is completed, the collapse cylinder needs to be lifted up. At the same time, in order to prevent the lifted collapse cylinder from touching the barrel body, the collapse cylinder is divided into two groups of collapse half-cylinders. Two groups of collapse components are set with the first motor as the symmetry center. The two groups of collapse half-cylinders need to rise vertically first and then move horizontally. Therefore, this is achieved through vertical movement components and horizontal movement components. The vertical movement component consists of a vertical movement plate, a sixth cylinder, a vertical movement seat and a third guide rail. The collapse half-cylinder is connected to the vertical movement seat through a connecting rod, and the sixth cylinder drives the vertical movement seat to move up and down on the third guide rail, thereby realizing the up and down movement effect of the collapse half-cylinder. The transverse movement component is composed of a fifth cylinder, a transverse movement seat and a second guide rail. The vertical movement plate is connected to the lower end of the transverse movement seat through the third cylinder. The transverse movement seat is driven by the fifth cylinder to move laterally on the second guide rail, thereby realizing the left and right transverse movement effect of the collapse half-cylinder. Therefore, the two groups of collapse half-cylinders are moved upward by simultaneously driving the sixth cylinder while maintaining the collapse cylinder, so that the concrete in the collapse cylinder can be lifted while maintaining the verticality, causing the concrete to collapse. After moving upward, the collapse cylinder is driven by the fifth cylinder to separate the two groups of collapse half-cylinders, so that the two groups of collapse half-cylinders gradually move away from each other and keep from touching the barrel body.

[0017] After the collapse of concrete is completed, the slump value of concrete needs to be measured, that is, the height difference between the height of the collapse cylinder and the highest point of the concrete entity after collapse is measured. The current solution is to use a protractor and a ruler for field measurement manually, but manual measurement will always have errors and is not objective enough. Therefore, in order to achieve a better measurement of the slump value, first of all, the height of the collapse cylinder is needed as a reference, and secondly, the horizontal scanning of the collapsed concrete is needed. Therefore, a scanning component is set up, and the collection plate and the launch plate are set parallel and perpendicular to the lifting plate. The projection surface between the collection plate and the launch plate includes the collapsed half cylinder and the collapsed concrete. A touch switch is set on the lifting plate. After the collapsed half cylinder is laterally displaced to the upper end of the touch switch, the collapsed half cylinder is driven by the sixth cylinder Move down, and the setting of the third cylinder can extend the up and down moving distance until the collapse half-cylinder is pressed against the touch switch on the lifting plate. Therefore, the collapse half-cylinder is abutted against the lifting plate in a state perpendicular to the lifting plate. At this time, the detection light emitted by the probe on the transmitting plate will hit the collection plate, and the detection light in the area blocked by the collapse half-cylinder and the collapsed concrete cannot pass through. Therefore, the area on the collection plate that does not receive the detection light is the outline shape of the collapse half-cylinder and the collapsed concrete. The drawing information on the collection plate is sent to the computer, and the height difference between the height of the collapse cylinder and the highest point of the concrete entity after the collapse can be obtained through the same scale. The data is displayed through the equipment and computer image display, and the data is more stable and reliable, and can be stored in the computer, so that the detection image data is retained for each operation.

[0018] Furthermore, the second guide rail includes two groups, the two groups of the second guide rails are respectively arranged on the two groups of cross bars, the transverse movement seats are respectively connected to the two groups of second guide rails, and the third cylinder passes through the two groups of cross bars from bottom to top and is connected to the transverse movement seat; the vertical movement plate is provided with a transversely penetrating accommodating hole, the sixth cylinder is arranged in the accommodating hole, the third guide rail and the vertical movement seat are both arranged on the side of the vertical movement plate facing away from the mixing assembly, the connecting rod passes through the accommodating hole and is connected to the vertical movement seat, and the lower end of the connecting rod abuts against the lower end of the accommodating hole.

[0019] Furthermore, it also includes a driving wheel group, which includes a second motor, a first gear, a second gear and a third gear. The second motor is connected to the outer wall of the first motor, the output end of the second motor is connected to the first gear, the second gear is connected to the output shaft of the first motor through a bearing, and the third gear is connected to the top of the mixing stick, and the first gear, the second gear and the third gear are meshed in sequence; the mixing assembly also includes a water tank, which is connected to the outer wall of the first motor, an atomizer is provided at the lower end of the water tank, and the nozzle on the atomizer points downward to the mixing stick; a buffer groove is provided on the third gear, a through hole connected to the inner cavity of the mixing stick is provided in the buffer groove, and an atomization hole connected to the inner cavity is provided on the outer wall of the mixing stick; the buffer groove and the nozzle are abutted and connected, and the nozzle is connected to the inner cavity of the mixing stick.

[0020] Compared with the prior art, the advantages of the present invention are as follows: through the linkage of the second cylinder, the first motor and the fourth cylinder, after the tamping stick is inserted into the collapse cylinder, tamping up and down and tamping in a spiral direction from the outside to the center can be achieved, thereby ensuring that the concrete can completely fill every corner of the collapse cylinder, and through the linkage of the fifth cylinder, the sixth cylinder and the third cylinder, the concrete in the collapse cylinder can be lifted while maintaining verticality, so that the concrete collapses, and the collapse cylinder after moving up is driven by the fifth cylinder to separate the two groups of collapse half cylinders, so that The two groups of collapse half-cylinders gradually move away from each other and do not touch the barrel body. The detection light emitted by the probe on the transmitting board hits the collecting board. The area on the collecting board that does not receive the detection light is the outline shape of the collapse half-cylinder and the collapsed concrete. The drawing information on the collecting board is sent to the computer, and the height difference between the height of the collapse cylinder and the highest point of the concrete entity after the collapse can be obtained through the same scale. The data is displayed through the equipment and computer image display. The data is more stable and reliable, and can be stored in the computer, so that the detection image data is retained for each operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] Description of the working method of the present invention:

[0049] In order to detect and calculate the slump expansion degree, the concrete detection device using this structure must first meet two conditions. One is that after the slump cone 35 is filled with concrete, the mixing rod 24 can be inserted into the slump cone 35 to stir the concrete up and down and to insert and stir the concrete in a spiral direction from the outside to the center so that the concrete can completely fill the entire space of the slump cone 35. The other is that after the slump cone 35 is filled, the slump cone 35 needs to be lifted vertically upward.

[0050] Therefore, in order to realize the up and down mixing of the mixing rod 24 in the slump cylinder 35, it is necessary to realize the up and down movement. Therefore, at the upper end of the frame 1 composed of the side frame 11 and the bottom plate 12, two sets of parallel and non-contacting cross bars 16 are horizontally placed, and a hoop 17 is provided on the cross bar 16. The circular structure formed by the two sets of hoop 17 encloses the barrel body 42 and fixes the barrel body 42, and at the same time abuts against the lower end of the outwardly extending plate at the upper end opening of the barrel body 42 to provide an upward support force for the barrel body 42. The upper end of the barrel body 42 The opening is covered with a barrel cover 41, and the second cylinder 21 is connected to the barrel cover 41. The output end of the second cylinder 21 extends into the inner cavity of the barrel body 42, and the first motor 22 is connected to the output end of the second cylinder 21. The output end of the first motor 22 is connected to the center of the rotating disk 23. The rotating groove 232 in the notch 231 on the edge of the rotating disk 23 cooperates with the plug-in column 242 of the sleeve 241 on the outer side wall of the stirring stick 24. Therefore, when the second cylinder 21 is driven, the stirring stick 24 can move up and down, and when the second cylinder 21 is driven, the stirring stick 24 can move up and down. When driven by a motor 22, the stirring rod 24 will rotate with the rotating disk 23 as the rotation center, so the stirring rod 24 can also rotate in a spiral direction, but it still cannot move from the outside to the center. Therefore, a rotating seat 233 is provided on the rotating disk 23, and the rotating seat 233 is rotatably connected to the fourth cylinder 234. The output end of the fourth cylinder 234 is rotatably connected to the rotating column 243 on the sleeve 241. Therefore, during the pushing process of the fourth cylinder 234, the upper end of the stirring rod 24 The end will move outward, causing the lower end of the mixing stick 24 to rotate in the opposite direction. The farther it is pushed, the greater the inclination angle of the lower end of the mixing stick 24. Therefore, the inclination angle of the lower end of the mixing stick 24 can be changed during the retraction of the fourth cylinder 234. Therefore, under the linkage of the second cylinder 21, the first motor 22 and the fourth cylinder 234, after the mixing stick 24 is extended into the collapse cone 35, it can be mixed up and down and inserted in a spiral direction from the outside to the center, so as to ensure that the concrete can fill every corner of the collapse cone 35.

[0051] In addition to manual filling, in order to realize automatic filling of concrete in the collapse cone 35, a feeding barrel 422 is arranged on the barrel body 42, and the lower end opening of the feeding barrel 422 points to the extension hole 421, and the lower end of the extension hole 421 is the collapse cone 35. Therefore, concrete can be filled into the collapse cone 35 by putting it in the feeding barrel 422. In the process of filling the collapse cone 35 with concrete, the first motor 22 will be stopped to drive the rotating disk 23 to rotate first, and then the second cylinder 21, the first motor 22 and the fourth cylinder 234 will be started to perform linkage tamping after the filling is completed. If necessary, a quantitative divider can be set at the lower end opening of the feeding barrel 422, so that concrete can be quantitatively placed in the collapse cone 35, so as to achieve the standard requirement of adding one-third of the height of the collapse cone 35 before each tamping. Since the quantitative divider is a relatively conventional existing technology, it will not be elaborated here.

[0052] As the mixing rod 24 is mixing up and down in the collapse cone 35, it needs to gradually rise and eventually leave the area where the collapse cone 35 is located. Therefore, the collapse cone 35 needs to be able to remain fixed on the lifting plate 14 while the lifting plate 14 must also be able to move up and down. Therefore, the lifting plate 14 and the bottom plate 12 are connected by the first cylinder 13, and the lifting plate 14 is moved up and down by driving the first cylinder 13. The lifting plate 14 cooperates with the first slide rail 15 to keep the lifting plate 14 moving up and down smoothly.

[0053] After the concrete filling in the slump cylinder 35 is completed, the slump cylinder 35 needs to be lifted up. At the same time, in order to prevent the lifted slump cylinder 35 from touching the barrel body 42, the slump cylinder 35 is divided into two groups of slump half cylinders 34. Two groups of slump components 3 are set with the first motor 22 as the symmetry center. The two groups of slump half cylinders 34 need to be vertically raised first and then horizontally translated. Therefore, this is achieved through the vertical movement member 32 and the horizontal movement member 31. The vertical movement member 32 is composed of a vertical movement plate 321, a sixth cylinder 322, a vertical movement seat 323 and a third guide rail 324. The slump half cylinder 34 is connected by a connecting rod 35. 1 is connected to the vertical shift seat 323, and the vertical shift seat 323 is driven by the sixth cylinder 322 to move up and down on the third guide rail 324, so as to achieve the up and down movement effect of the collapse half cylinder 34. In order to achieve a more stable movement effect of the vertical shift seat 323, a transversely penetrating accommodation hole 325 is set on the vertical shift plate 321. The third guide rail 324 and the vertical shift seat 323 are both set on the side of the vertical shift plate 321 facing away from the mixing assembly 2. The connecting rod 351 passes through the accommodation hole 325 and is connected to the vertical shift seat 323. At the same time, the lower end of the connecting rod 351 abuts against the lower end of the accommodation hole 325, so as to give the connecting rod 351 a stable movement effect. The up and down movement positions of the rod 351 are limited, which also provides a more stable effect; the transverse member 31 is composed of the fifth cylinder 311, the transverse seat 312 and the second guide rail 313. The vertical plate 321 is connected to the lower end of the transverse seat 312 through the third cylinder 33. The transverse seat 312 is driven by the fifth cylinder 311 to move laterally on the second guide rail 313, thereby achieving the left and right transverse movement effect of the collapsed half cylinder 34. At the same time, in order to ensure that the transverse seat 312 can also stably move laterally and disperse stress, two sets of second guide rails 313 are arranged in parallel, and the transverse seat 312 is connected to the two sets of second guide rails 313 in coordination. 3, the third cylinder 33 passes through the two sets of cross bars 16 and is connected to the transverse seat 312, so that the stability and stress dispersion of the transverse seat 312 can be well achieved; therefore, the two sets of collapse half cylinders 34 are moved upward by driving the sixth cylinder 322 while maintaining the collapse cylinder 35, so that the concrete in the collapse cylinder 35 can be lifted while maintaining the verticality, so that the concrete collapses, and the collapse cylinder 35 after moving upward is driven by the fifth cylinder 311 to separate the two sets of collapse half cylinders 34, so that the two sets of collapse half cylinders 34 gradually move away from each other and keep not touching the barrel body 42.

[0054] In order to prevent the collapse cylinder 35 composed of two collapse half cylinders 34 from being separated by external force during the insertion of the mixing rod 24, in addition to abutting the two collapse half cylinders 34 through the fifth cylinder 311 of the transverse member 31, vertical matching buckles can also be provided on the two collapse half cylinders 34, and the buckles can be opened by the up and down staggered movement of the vertical moving member 32, so as to keep the two collapse half cylinders 34 abutted and avoid separation.

[0055] After the collapse of the concrete is completed, it is necessary to measure the slump value of the concrete, that is, to measure the height difference between the height of the slump cone 35 and the highest point of the concrete entity after the collapse. The current solution is to use a protractor and a ruler to perform on-site measurements manually, but manual measurements will always have errors and are not objective enough. Therefore, in order to achieve a better measurement of the slump value, first of all, the height of the slump cone 35 is required as a reference, and secondly, a transverse scan of the collapsed concrete is required. Therefore, a scanning component 5 is set, and the collection plate 51 and the launch plate 52 are set parallel to and perpendicular to the lifting plate 14. The projection surface between the collection plate 51 and the launch plate 52 includes the collapsed half cylinder 34 and the collapsed concrete. A touch switch 18 is set on the lifting plate 14. After the collapsed half cylinder 34 is laterally displaced to the upper end of the touch switch 18, the collapsed half cylinder 34 is moved downward by driving the sixth cylinder 322, and the setting of the third cylinder 33 can extend the distance of the up and down movement. , until the collapsed half cylinder 34 is pressed against the touch switch 18 on the lifting plate 14, so that the collapsed half cylinder 34 is in contact with the lifting plate 14 in a state perpendicular to the lifting plate 14. At this time, the detection light emitted by the probe 521 on the transmitting plate 52 will hit the collecting plate 51, and the detection light in the area blocked by the collapsed half cylinder 34 and the collapsed concrete cannot pass through. Therefore, the area on the collecting plate 51 where the detection light is not received is the contour shape of the collapsed half cylinder 34 and the collapsed concrete. The pattern information on the collecting plate 51 is sent to the computer, and the height difference between the height of the collapse cylinder 35 and the highest point of the concrete entity after the collapse can be obtained through the same scale. The data is displayed through the equipment and computer image display, and the data is more stable and reliable, and can be stored in the computer, so that the detection image data is retained for each operation, and the contour display is performed on the collecting plate 51 by the detection light. This is a currently achievable technology, so I will not go into details here.

[0056] Example 2

[0057] like Figure 9-15 As shown, it also includes a driving wheel group, which includes a second motor, a first gear, a second gear and a third gear. The second motor is connected to the outer wall of the first motor, the output end of the second motor is connected to the first gear, the second gear is connected to the output shaft of the first motor through a bearing, and the third gear is connected to the top of the mixing stick, and the first gear, the second gear and the third gear are meshed in sequence; the mixing assembly also includes a water tank, which is connected to the outer wall of the first motor, an atomizer is provided at the lower end of the water tank, and the nozzle on the atomizer points downward to the mixing stick; a buffer groove is provided on the third gear, a through hole connected to the inner cavity of the mixing stick is provided in the buffer groove, and an atomization hole connected to the inner cavity is provided on the outer wall of the mixing stick; the buffer groove and the nozzle are abutted and connected, and the nozzle is connected to the inner cavity of the mixing stick.

[0058] Because the inner wall of the slump cone 35 and the lifting plate 14 need to be kept moist and free of visible water before the slump cone 35 is filled with concrete, a water tank 26 is added, and an atomizer 261 is added at the lower end of the water tank 26. The nozzle 262 of the atomizer 261 points to the mixing rod 24. A plurality of atomizing holes 244 connected to the inner cavity are provided on the outer wall of the mixing rod 24. Because the mixing rod 24 is tilted at an angle under the drive of the fourth cylinder 234, the mixing rod 24 can only be realized when it is vertical. The nozzle 262 is now pointed vertically to the stirring rod 24, and in order for the through hole 2542 connected to the inner cavity of the stirring rod 24 to dock with the nozzle 262, the third gear 254 needs to avoid the nozzle 262. Therefore, a buffer groove 2541 is provided on the third gear 254 to cooperate with the nozzle 262. Therefore, the stirring rod 24 is first extended into the inner space of the slump cylinder 35, and the atomized water in the atomizer 261 can be sprayed outward through the atomizing hole 244, but a simple atomized spray The atomization effect of the mixing rod 24 on the inner wall of the collapse cone 35 is more uniform. At the same time, after the concrete is mixed, the atomizer 261 is started to clean the outer surface of the mixing rod 24 through the water vapor on the atomization hole 244.

[0059] The beneficial effect of the present invention is that: through the linkage of the second cylinder 21, the first motor 22 and the fourth cylinder 234, after the tamping stick 24 is inserted into the slump cone 35, it can be tamped up and down and inserted in a spiral direction from the outside to the center, thereby ensuring that the concrete can completely fill every corner of the slump cone 35, and through the linkage of the fifth cylinder 311, the sixth cylinder 322 and the third cylinder 33, the concrete in the slump cone 35 can be lifted while maintaining verticality, so that the concrete collapses, and the slump cone 35 after moving up is driven by the fifth cylinder 311 to separate the two groups of slump half cylinders 34 , so that the two groups of collapsed half cylinders 34 gradually move away from each other and keep from touching the barrel body 42, and then the detection light emitted by the probe 521 on the transmitting plate 52 hits the collecting plate 51. The area on the collecting plate 51 that does not receive the detection light is the contour shape of the collapsed half cylinder 34 and the collapsed concrete. The pattern information on the collecting plate 51 is sent to the computer, and the height difference between the height of the collapse cylinder 35 and the highest point of the concrete entity after collapse can be obtained through the same scale. The data is displayed through the equipment and computer image display, and the data is more stable and reliable, and can be stored in the computer, so that the detection image data is retained for each operation.
