Description

Technical Field

[0001] This application relates to the technical field of building detection, and particularly to a building compressive strength detection device and method. Background Art

[0002] A building is an artificial structure, and its wall is an important part of the building. Its functions are to bear weight, enclose and separate spaces. After the wall is built, it is necessary to detect its compressive and seismic resistance strengths to ensure that the wall has sufficient stability.

[0003] In the prior art, such as a building wall compressive strength detection device with the publication number CN212275438U, including a base, a limiting cover and a fixing frame are respectively and fixedly installed on the top of the base, and a linkage plate located between the limiting cover and the fixing frame is slidably connected to the top of the base. In this utility model, by rotating the screw rod, four U-shaped clamping plates can be used to stably clamp the test plate. Therefore, when applying pressure to the test plate, the problem of the test plate slipping off will not occur. After that, starting the driving motor can make the pressing plate extrude the test plate, and the maximum pressure value that the test plate can bear can be recorded by the pressure sensor, so as to accurately test the test plate.

[0004] The above prior art determines the compressive strength of the wall by pouring a concrete test plate used for pouring the wall and detecting the compressive strength of the test plate. However, the compressive strength of the wall is not limited to the concrete mix ratio, and is also related to the usage mode and pouring density during the wall pouring. Therefore, it is not accurate to judge the compressive strength of the wall by detecting the test plate; secondly, if the compressive strength of each type of wall is detected, it is necessary to prepare test plates corresponding to the walls, which will consume a lot of concrete materials and cause unnecessary waste; in addition, by detecting the test plate, only the overall compressive strength of the wall can be judged, and it does not accurately reach the compressive strength of different positions of the wall. Just as mentioned above, the compressive strength of the wall is related to the usage mode and pouring density during the wall pouring, and there are uncertain factors, which will cause differences in different positions of the wall.

[0032] In summary, the present application includes at least one of the following beneficial technical effects:

[0033] 1. The present invention drills a hole in the wall through the drilling and material taking unit to take out a part of the wall, and then the detection unit on the mobile detection vehicle performs compressive strength testing on this part of the wall, which is convenient and fast. At the same time, the present invention can drill and take materials at any position of the wall to more accurately detect the compressive strength of the wall.

[0034] 2. When the present invention drills and takes materials from the wall through the sawtooth ring, the drilling ring can absorb the smoke and dust gas generated during drilling, preventing the smoke and dust gas from directly diffusing into the external environment. At the same time, the smoke and dust gas absorbed by the drilling ring is filtered by the reservoir. To improve the absorption efficiency of the drilling ring for the smoke and dust gas, the present invention uses a second air pump to blow the gas in the external environment into the blowing groove, so as to improve the blowing holes blowing towards the drilling hole, improve the gas flow exchange in the drilling hole, and then accelerate the absorption of the smoke and dust gas.

[0035] 3. The present invention can flip the drilling ring clamping the wall by 90° through the flipping mechanism to ensure that the wall in the drilling ring is smoothly placed in the placement groove on the mobile detection vehicle, facilitating the compressive strength detection of the wall by the detection unit; its insertion strip cooperates with the card slot of the U-shaped base to limit the L-shaped support plate. At the same time, the clamping rod can be clamped through the cooperation of the clamping seat and the insertion strip, so that the gravity block pulls the clamping rod through the steel wire rope under the action of the U-shaped support frame to realize the upward flipping of the L-shaped support plate by 90°.

Detailed implementation manners

[0048] The following further elaborates on this application Figure 1-11 in conjunction with the attached drawings.

[0049] Embodiment 1: An embodiment of the present application discloses a building compressive strength detection device and method. By drilling holes in the wall to take out a part of the wall material, and then detecting the compressive strength of the material, the compressive strength of the building wall is judged through the detection of the material.

[0050] Referring to Figure 1 , specifically, a building compressive strength detection device includes a mobile detection vehicle 1. A drilling and material taking unit 2 is installed at the upper end of the mobile detection vehicle 1 through an existing elevator. A detection unit for detecting the compressive strength of the wall is arranged inside the mobile detection vehicle 1.

[0051] By setting the mobile detection vehicle 1 that integrates drilling and material taking and compressive strength detection, the compressive strength of any wall of the building can be detected. It is flexible to move, convenient to carry, and convenient to detect. Compared with the traditional method of judging the wall strength by testing the compressive strength of the test board of the wall, although the test board and the wall are both cast with the same concrete, there will be differences in the casting operation (such as the possibility of different densities when casting concrete). Therefore, it is not accurate to judge the compressive strength of the wall by detecting the test board.

[0052] Therefore, in this embodiment, the drilling and material taking unit 2 drills holes in the wall to take out a part of the wall, and the detection unit on the mobile detection vehicle 1 tests the compressive strength of this part of the wall. The detection unit is a prior art, such as a pressure testing machine. It should be noted that when drilling and taking materials from load-bearing walls, the steel bar area needs to be avoided to prevent damage to the steel bar support structure of the load-bearing wall.

[0053] The drilling and material taking unit 2 includes a U-shaped base 3 installed on the top of an existing elevator. An L-shaped support plate 4 is arranged inside the U-shaped base 3. The corner of the L-shaped support plate 4 is rotatably installed inside the U-shaped base 3 through a rotating shaft. A drilling and material taking mechanism 5 is arranged on the vertical section of the L-shaped support plate 4 for drilling and taking materials from the wall. A flipping mechanism 6 is arranged between the horizontal section of the L-shaped support plate 4 and the mobile detection vehicle 1 for placing the materials taken out by drilling.

[0054] In the specific implementation process, the up and down movement of the U-shaped base 3 is controlled by an existing elevator. When the U-shaped base 3 moves up to the designated position, the flipping mechanism 6 is used to ensure that the drilling and material taking mechanism 5 remains horizontal, so as to facilitate the drilling and material taking mechanism 5 to drill holes in the wall. After the drilling and material taking mechanism 5 drills out a part of the wall, the U-shaped base 3 is moved down to the designated position again through the existing elevator, and the flipping mechanism 6 is used to make the drilling and material taking mechanism 5 remain vertical, so that the taken-out wall can be put into the mobile detection vehicle 1 for the detection unit to detect the compressive strength of the wall.

[0055] Referring to Figures 2-3, wherein, the drilling and material taking mechanism 5 includes a bearing ring 51 fixed on the vertical section of the L-shaped support plate 4. The front end of the bearing ring 51 is rotatably installed with a collecting end cover 52 that penetrates through from front to back. An air inlet collar 53 is installed at the front end of the collecting end cover 52. A disc 54 is arranged on the inner side wall at the front end of the collecting end cover 52. The air inlet collar 53 is rotatably connected to the rear end of the drilling ring 55 and they are in sealed cooperation. The disc 54 is in rotational contact with the rear end of the drilling ring 55. The front end of the drilling ring 55 is installed with a serrated ring 56 for drilling through a detachable manner.

[0056] The serrated ring 56 at the front end of the drilling ring 55 rotates to drill the wall. A part of the wall taken out by drilling is clamped inside the drilling ring 55. At the same time, dust will be generated during the drilling process, and the drilling ring 55 can absorb the generated dust and then converge into the collecting end cover 52 to prevent the dust from spreading everywhere. In order to improve the efficiency of the drilling ring 55 in absorbing dust, the outside air enters the drilling ring 55 through the air inlet collar 53 and then blows into the hole in the wall to improve the gas exchange efficiency in the hole, thereby further improving the dust absorption efficiency.

[0057] Refer to Figure 4 , in order to ensure that the drilling ring 55 can successfully drill and take materials from the wall, in this embodiment, an external gear ring 57 is installed on the outer side wall of the drilling ring 55. The external gear ring 57 is externally meshed with a driving gear 59 installed on the output end of the drilling motor 58. The drilling motor 58 is installed on the auxiliary support frame 510 through a motor base. The auxiliary support frame 510 is rotatably matched with the drilling ring 55 through a bearing, and a plurality of stroke hydraulic cylinders 511 for pushing the drilling ring 55 to move are connected between the auxiliary support frame 510 and the vertical section of the L-shaped support plate 4.

[0058] In the specific implementation process, the drilling motor 58 drives the external gear ring 57 to rotate through the driving gear 59, and then makes the drilling ring 55 drive the serrated ring 56 to rotate synchronously so that the serrated ring 56 can drill the wall. At the same time, the stroke hydraulic cylinder 511 pushes the auxiliary support frame 510 rotatably installed on the outer side wall of the drilling ring 55, and then makes the drilling ring 55 and the serrated ring 56 have a driving force to move towards the wall, ensuring the smooth progress of the drilling and material taking of the drilling ring 55 on the wall.

[0059] Look back Figure 1 , when the serrated ring 56 just starts to drill the wall, the drilling ring 55 has not yet entered the drilled hole, so that the drilling ring 55 cannot absorb the dust yet. Therefore, an elastically telescopic telescopic frame 5101 is installed at the front end of the auxiliary support frame 510. The telescopic frame 5101 can prevent the dust from spreading, so as to facilitate the drilling ring 55 to absorb the dust in the telescopic frame 5101.

[0060] Refer to Figures 5-6, when the serrated ring 56 drills holes in the wall, not only will there be soot generated, but also particulate matter will be generated. Therefore, when the drilling ring 55 absorbs soot, it will also absorb particulate matter. To prevent particulate matter from entering the drilling ring 55; specifically, a number of arc-shaped air collecting holes 551 are evenly arranged in the circumferential direction at the rear end of the drilling ring 55, and a number of air suction holes communicating with the arc-shaped air collecting holes 551 are evenly arranged in the circumferential direction on both the inner and outer side walls of the drilling ring 55. The air suction plates 552 are installed in the air suction holes in a detachable manner, and a number of frustum-shaped air inlet holes 5521 are arranged on the air suction plates 552. The diameter of one end of the air inlet hole 5521 facing the arc-shaped air collecting hole 551 is larger than the diameter of the other end of the air inlet hole 5521.

[0061] Installing the air suction plate 552 in a detachable manner facilitates the replacement of the air suction plate 552 and the cleaning of the air inlet holes 5521 in the later stage. The soot in the holes enters the arc-shaped air collecting holes 551 through the air inlet holes 5521, and larger particulate matter in the drilling holes cannot enter the air inlet holes 5521; when the particulate matter blocks the air inlet holes 5521, due to the rotation of the drilling ring 55, the side wall of the air suction plate 552 is in sliding contact with the wall, which can squeeze and scrape away the particulate matter or squeeze the particulate matter into the air inlet holes 5521. Since the diameter of one end of the air inlet hole 5521 facing the arc-shaped air collecting hole 551 is larger than the diameter of the other end of the air inlet hole 5521, as long as the particulate matter passes through the entrance of the air inlet hole 5521, it can smoothly enter the arc-shaped air collecting hole 551, effectively preventing the particulate matter from blocking the air inlet holes 5521 and affecting the absorption of soot.

[0062] Looking back Figure 3 , after the soot enters the arc-shaped air collecting holes 551, in order to ensure that the soot in the arc-shaped air collecting holes 551 is smoothly transported to the collecting end cover 52, a number of discharge holes 541 are evenly arranged in the circumferential direction at one end of the disc 54 facing the arc-shaped air collecting holes 551, and the discharge holes 541 are directly opposite to the arc-shaped air collecting holes 551. The soot is transported to the collecting end cover 52 through the discharge holes 541 on the outer circumference of the disc 54.

[0063] In order to process the soot gas converging in the collecting end cover 52, in this embodiment, a gas collecting ring is installed at the rear end of the collecting end cover 52. The gas collecting ring includes a frustum-shaped hollow ring 521 at the front end and a cylindrical hollow ring 522 at the rear end. A first air pump 523 is installed at the rear end of the cylindrical hollow ring 522, and the air inlet end of the first air pump 523 is communicated with the cylindrical hollow ring 522. The air outlet end of the first air pump 523 is communicated with a connecting hose 524. A water reservoir 11 for filtering waste gas is provided on the mobile detection vehicle 1 (shown in Figure 1 ), and one end of the connecting hose 524 away from the first air pump 523 is led into the water reservoir 11.

[0064] In the specific implementation process, under the action of the first air pump 523, the soot gas in the collection end cover 52 is transported to the connecting hose 524 after passing through the air collecting ring, and finally introduced into the water storage tank 11 on the mobile detection vehicle 1. The water in the water storage tank 11 is used to filter the soot gas, and the soot can be left in the water, while the gas is discharged into the external environment. It should be noted that the connecting hose 524 is reserved with sufficient length to ensure that the lower end of the connecting hose 524 is still introduced into the water storage tank 11 when the drilling ring 55 is moved up to the highest position.

[0065] There are many particulate matters in the soot gas converging in the collection end cover 52. To prevent the particulate matters from entering the first air pump 523 and damaging the first air pump 523, a detachable filter screen plate 525 is provided on the inner side wall of the rear end of the collection end cover 52. A rotating shaft 526 is rotatably installed in the middle of the front end of the filter screen plate 525. A scraping strip 527 with a planar spiral structure is provided at the front end of the filter screen plate 525, and the scraping strip 527 is in sliding contact with the filter screen plate 525. One end of the middle part of the scraping strip 527 is connected to the rotating shaft 526. The end of the rotating shaft 526 facing the cylindrical hollow ring 522 penetrates through the filter screen plate 525 into the cylindrical hollow ring 522, and a plurality of spiral blades 528 are evenly installed in the circumferential direction at its end.

[0066] In the specific implementation process, when the soot gas is introduced into the air collecting ring, it needs to pass through the filter screen plate 525, and the filter holes on the filter screen plate 525 are used to filter the soot gas so as to filter out the particulate matters in the soot gas. To prevent the particulate matters from blocking the filter holes, in this embodiment, the filter screen plate 525 is scraped by the scraping strip 527 with a planar spiral structure so as to scrape off the particulate matters on the filter screen plate 525. The scraping strip 527 in this embodiment has a planar spiral structure, which can push the particulate matters on the filter screen plate 525 towards the outside of the filter screen plate 525, avoiding a lot of particulate matters sticking to the scraping strip 527, thus affecting the scraping of the filter screen plate 525 by the scraping strip 527. When the soot gas enters the cylindrical hollow ring 522 through the filter screen plate 525, it will push the spiral blades 528 on the rotating shaft 526 to rotate, and then drive the scraping strip 527 with a planar spiral structure to rotate synchronously through the rotation of the rotating shaft 526, so as to realize the scraping of the filter screen plate 525 by the scraping strip 527.

[0067] The particulate matter scraped by the scraping bar 527 will accumulate in the collection end cap 52, and there will be a lot of soot gas in the collection end cap 52. This makes it easy for the accumulated particulate matter to be mixed in the soot gas again, further increasing the difficulty of filtering the soot gas by the filter plate 525. Therefore, it is necessary to clean out the particulate matter scraped by the scraping bar 527 in time. Specifically, a material retaining ring 529 with an L-shaped cross-section is provided on the outer side wall of the front end of the filter plate 525. One end of the scraping bar 527 away from the rotating shaft 526 is located inside the material retaining ring 529. A through hole is opened at the bottom of the material retaining ring 529, and the through hole penetrates the bottom of the collection end cap 52. A vertically through guiding frame 5210 is connected between the bottom of the material retaining ring 529 and the bottom of the collection end cap 52. The through hole at the bottom of the material retaining ring 529 is communicated with the through hole at the bottom of the collection end cap 52 through the guiding frame 5210. The bottom of the collection end cap 52 is detachably provided with a collection frame 5211, and the collection frame 5211 is located directly below the through hole.

[0068] In the specific implementation process, the particulate matter scraped by the scraping bar 527 will converge in the material retaining ring 529, and then enter the collection frame 5211 through the through hole of the material retaining ring 529, the guiding frame 5210 and the through hole at the bottom of the collection end cap 52 in sequence. After that, only need to remove the collection frame 5211 and clean the particulate matter inside the collection frame 5211.

[0069] Refer to Figure 7 , in order to ensure the smooth flow of gas in the drill hole, in this embodiment, a blowing groove 553 is opened in the drill ring 55. A plurality of air blowing holes 554 communicating with the blowing groove 553 are evenly circumferentially opened on the inner and outer side walls of the front end of the drill ring 55. A plurality of air inlets 555 are evenly circumferentially opened on the outer side wall of the rear end of the drill ring 55. An air storage groove 531 is evenly circumferentially opened on the inner side wall of the air inlet sleeve ring 53. The air storage groove 531 is communicated with the blowing groove 553 through the air inlet 555. An air inlet pipe 532 (shown in Figure 2 is communicated with the outer side wall of the air inlet sleeve ring 53. One end of the air inlet pipe 532 away from the air inlet sleeve ring 53 is communicated with a second air pump 533 (shown in Figure 2 installed on the L-shaped support plate 4).

[0070] In the specific implementation process, the second air pump 533 transports the outside air to the air storage groove 531 in the air inlet sleeve ring 53 through the air inlet pipe 532, then enters the blowing groove 553 through the air inlet 555, and finally blows towards the drill hole through the air blowing holes 554 on the inner and outer side walls of the drill ring 55 to improve the gas flow in the drill hole and facilitate the soot gas in the drill hole to enter the arc-shaped air collecting hole 551.

[0071] Refer to Figures 8-9When the serrated ring 56 drills a hole through the wall, in order to ensure that the drilling ring 55 can smoothly remove the wall inside the drilling ring 55, in this embodiment, a plurality of retreat grooves are evenly opened on the inner side wall of the front end of the drilling ring 55 in the circumferential direction, and a supporting block 556 is installed in the retreat groove through a rotating shaft, and a torsion spring (not shown in the figure) is connected between the rotating shaft and the retreat groove.

[0072] In the specific implementation process, after the serrated ring 56 drills through the wall, the supporting block 556 rotates out of the retreat groove under the action of the torsion spring. When the drilling ring 55 withdraws from the drilling hole, the supporting block 556 will press against the wall inside the drilling ring 55, so that the wall moves out synchronously with the drilling ring 55, so that the removed wall can be tested for compressive strength later.

[0073] Example 2: Reference Figure 10 On the basis of the first embodiment, in order to ensure that the wall taken out by the drilling ring 55 is smoothly moved to the mobile inspection vehicle 1; specifically, the flip mechanism 6 includes a U-shaped support frame 61 fixed to the upper end of the mobile inspection vehicle 1, and the left and right ends of the top of the U-shaped support frame 61 are installed with lifting blocks 68, and the opposite ends of the top of the lifting block 68 are provided with a slope; a buckle assembly 69 is provided between the horizontal section of the L-shaped support plate 4 and the U-shaped base 3; the buckle assembly 69 includes a moving groove opened on the left and right sides of the horizontal section of the L-shaped support plate 4, and a plug strip 692 is slidably arranged in the moving groove through a moving spring (not shown in the figure), and the left and right inner walls of the U-shaped base 3 are provided with a clamping groove 693, and the horizontal section of the upper end of the plug strip 692 is slidably matched with the clamping groove 693, and the vertical section of the plug strip 692 is in contact with the slope of the lifting block 68.

[0074] In the specific implementation process, after the drilling ring 55 completes drilling and taking materials from the wall, the drilling ring 55 is lowered by a lift so that the wall taken out by the drilling ring 55 can be placed on the mobile inspection vehicle 1, and then the inspection unit performs a compressive strength test on the wall; when the drilling ring 55 moves down to a certain height, the two lifting blocks 68 on the top of the U-shaped support frame 61 contact with the insertion strip 692, and the lifting blocks 68 push the insertion strip 692 away from the U-shaped base 3 through the slope thereon, so that the horizontal section of the upper end of the insertion strip 692 moves out of the slot 693 on the U-shaped base 3, so that it can rotate downward under the action of the drilling and taking material mechanism 5 and the gravity of the part of the wall inside the drilling ring 55.

[0075] Furthermore, limit plates 41 are provided at the rear ends of the left and right sides of the vertical section of the L-shaped support plate 4, and the limit plates 41 are in contact with the upper end surface of the U-shaped base 3; when the limit plates 41 contact the U-shaped base 3 during the downward rotation of the vertical section of the L-shaped support plate 4, the L-shaped support plate 4 stops rotating, and at this time, it can ensure that the drilling ring 55 remains in a vertical downward state.

[0076] Replay Figure 8, Further, a placement groove 12 is provided at the upper end of the mobile detection vehicle 1, and a jacking column 121 is provided at the bottom of the placement groove 12. The jacking column 121 is slidably engaged with the inner side wall of the drilling ring 55. When the vertically placed drilling ring 55 drives the wall body inside it into the placement groove 12 on the mobile detection vehicle 1, the jacking column 121 at the bottom of the placement groove 12 will slide into the drilling ring 55. Before the jacking column 121 contacts the wall body, it will first contact the supporting block 556 and push the supporting block 556 to move into the retraction groove until the jacking column 121 contacts the wall body. Then the drilling ring 55 moves upward and exits the placement groove 12. Since the upper end of the supporting block 556 and the end far from the retraction groove are provided with inclined surfaces, at this time the supporting block 556 does not contact the wall body, so that the wall body can fall smoothly.

[0077] Continue to refer to Figures 10-11 , when the wall body in the drilling ring 55 is placed in the placement groove 12 and the drilling ring 55 needs to perform a compressive strength test on the wall body at another location, the drilling ring 55 needs to be lifted again by the elevator. At this time, the drilling ring 55 is in a vertical state. In order to realize a 90° flip of the drilling ring 55 during the upward movement; specifically, an elastic telescopic block 64 is installed at the top of the U-shaped support frame 61, a circular support seat 65 is installed at the upper end of the elastic telescopic block 64, and a support groove (not shown in the figure) is provided at the top of the circular support seat 65. A clamping rod 66 is placed in the support groove; a clamping seat 694 is provided on the lower end surface of the horizontal section of the L-shaped support plate 4 and between the two moving grooves. A groove matching the clamping rod 66 is provided on the lower end surface of the clamping seat 694. The horizontal section of the lower part of the insert bar 692 is slidably engaged with the clamping seat 694, and an arc-shaped groove (not shown in the figure) matching the clamping rod 66 is provided on the upper end surface of the horizontal section of the lower part of the insert bar 692.

[0078] Before the jacking block 68 touches the insert bar 692, the clamping rod 66 will first move into the groove of the clamping seat 694, and then the U-shaped base 3 continues to move downward so that the elastic telescopic block 64 is compressed downward under pressure until the jacking block 68 touches the insert bar 692 and drives the insert bar 692 to disengage from the clamping groove 693. At this time, the horizontal section of the lower part of the insert bar 692 moves to both ends of the clamping seat 694 and clamps the clamping rod 66 between the insert bar 692 and the clamping seat 694.

[0079] When the drilling ring 55 moves upward, the L-shaped support plate 4 can be automatically flipped 90° to keep the drilling ring 55 in a horizontal state. Therefore, guide grooves 62 are provided on the opposite sides of the two vertical sections of the U-shaped support frame 61. A gravity block 63 is slidably arranged between the two vertical sections of the U-shaped support frame 61 (shown in Figure 8 ), and both ends of the gravity block 63 are slidably arranged in the two guide grooves 62 respectively; both ends of the clamping rod 66 are connected with steel wire ropes 67, and the lower ends of the steel wire ropes 67 sequentially penetrate through the circular support seat 65 and the top of the U-shaped support frame 61 and are connected to the gravity block 63.

[0080] After the clamping rod 66 is clamped between the insert 692 and the clamping seat 694, the drilling ring 55 continues to move downward and causes the L-shaped support plate 4 to turn downward by 90°. At this time, the clamping rod 66 will be driven to rotate synchronously. The clamping rod 66 is connected to the gravity block 63 slidably arranged on the U-shaped support frame 61 through a steel wire rope 67, so that the gravity block 63 will also move upward along with the steel wire rope 67. After the drilling ring 55 places the wall from which the drilling is taken out into the placing groove 12, the drilling ring 55 moves upward. When the drilling ring 55 needs to perform a compressive strength test on another wall, the drilling ring 55 moves upward. When the drilling ring 55 moves upward to a certain height, the gravity block 63 also moves to the top of the U-shaped support frame 61. At this time, the U-shaped support frame 61 restricts the upward movement of the gravity block 63, so that the gravity block 63 can pull the L-shaped support plate 4 to rotate upward through the steel wire rope 67, thereby enabling the drilling ring 55 to maintain a horizontal state.

[0081] It should be noted that the gravity of the drilling and material taking mechanism 5 is greater than the gravity of the gravity block 63, that is, when the drilling ring 55 moves upward, the gravity block 63 cannot pull the L-shaped support plate 4 to turn upward.

[0082] Further, a horizontal plate 31 is connected to the rear end of the lower end surface of the U-shaped base 3. The upper end surface of the horizontal plate 31 is in horizontal contact with the upper end surface of the L-shaped support plate 4. When the horizontal section of the L-shaped support plate 4 contacts the horizontal plate 31, the L-shaped support plate 4 stops rotating. At this time, the drilling ring 55 maintains a horizontal state.

[0083] When the L-shaped support plate 4 rotates downward, the jacking block 68 will disengage from the abutting fit with the insert 692. At this time, the insert 692 will move in the direction away from the moving groove under the action of the moving spring, so that the lower part of the insert 692 disengages from the fit with the clamping seat 694, resulting in the clamping rod 66 disengaging from the fit with the clamping seat 694. Therefore, in this embodiment, a through jacking hole 6921 is provided in the horizontal section of the lower part of the insert 692. A mating strip 6922 is slidably arranged in the jacking hole 6921. An installation hole (not shown in the figure) is provided on the lower end surface of the clamping seat 694 opposite to the jacking hole 6921. An elastic block 6941 is arranged in the installation hole. The lower end of the elastic block 6941 is provided with an inclined surface facing one end of the clamping groove 693 of the U-shaped base 3, and the elastic block 6941 is slidably matched with the jacking hole 6921.

[0084] Under the interference and cooperation of the lifting block 68, the lower end of the insertion strip 692 moves toward the clamping seat 694. When the lower end of the insertion strip 692 moves to interfere with the inclined surface of the elastic block 6941 on the clamping seat 694, the elastic block 6941 is compressed and moved toward the mounting hole, so that the lower end of the insertion strip 692 moves smoothly until the insertion hole 6921 on the insertion strip 692 is opposite to the elastic block 6941, so that the elastic block 6941 moves into the insertion hole 6921, thereby restricting the insertion strip 692 on the clamping seat 694, and then the L-shaped support plate 4 can drive the clamping rod 66 to rotate synchronously; wherein the lower end of the matching strip 6922 in the insertion hole 6921 will move downward and disengage from the insertion hole 6921 under the action of gravity.

[0085] When the gravity block 63 pulls the clamping rod 66 through the wire rope 67 to complete the upward flipping of the L-shaped support plate 4, it is necessary to ensure that the clamping rod 66 automatically disengages from the connection with the clamping seat 694. Therefore, this embodiment has sliding grooves 311 on both sides of the left and right sides of the lower end surface of the horizontal plate 31, and a U-shaped resistance bar 312 is slidably arranged in the sliding groove 311. A tightening spring 313 is connected between the resistance bar 312 and the sliding groove 311, and the top of another vertical section of the resistance bar 312 away from the sliding groove 311 contacts the lower end surface of the insertion bar 692.

[0086] In the specific implementation process, when the lifting block 68 contacts and pushes the insertion strip 692 to move toward the clamping seat 694, the lower end of the matching strip 6922 in the insertion hole 6921 will contact the vertical section of the contact strip 312 located below the clamping seat 694, and push the contact strip 312 to move in the direction of compressing the clamping spring 313 until the elastic block 6941 moves down into the insertion hole 6921 to achieve the clamping and fixing of the clamping rod 66. When the L-shaped support plate 4 moves upward, the contact strip 312 breaks away from the contact with the matching strip 6922, and then pushes the contact strip 312 to compress the clamping spring 313 under the action of the clamping spring 313. When the L-shaped support plate 4 is flipped upward by 90°, the lower end of the mating strip 6922 will contact the contact strip 312 and push the mating strip 6922 upward in the insertion hole 6921 through the contact strip 312, so that the upper end of the mating strip 6922 pushes the elastic block 6941 to disengage from the insertion hole 6921, so that the moving spring in the movable groove can smoothly push the insertion strip 692 to move away from the clamping seat 694, thereby finally realizing the disconnection of the clamping rod 66 from the clamping seat 694.

[0087] Finally, the present invention also provides a method for detecting the compressive strength of a building, and the method for using the method comprises the following steps:

[0088] S1: Drilling preparation: the drilling and taking unit 2 is moved up to a suitable height by an existing elevator, and the drilling ring 55 is ensured to remain in a horizontal state by a flipping device.

[0089] S2: Drilling and material extraction. Start the drilling motor 58 to drive the drilling ring 55 to drive the sawtooth ring 56 to rotate, and at the same time cooperate with the stroke hydraulic cylinder 511 to push the drilling ring 55 towards the wall, so as to realize drilling the wall.

[0090] S3: Smoke and dust treatment. Deliver gas into the blowing groove 553 through the second air pump 533, so as to improve the blowing holes 554 to blow into the wall. At the same time, the first air pump 523 is started so that the smoke and dust in the wall enter the arc-shaped air collecting hole 551 through the suction holes, and finally are transported to the reservoir 11 through the connecting hose 524 to filter out the smoke and dust.

[0091] S4: Feeding detection. Once again, lower the drilling ring 55 to the mobile detection vehicle 1 through the existing elevator, so that the material in the drilling ring 55 is placed in the placement groove 12, so that the existing detection unit conducts a compressive strength test on the material.
