[0016] Compared with the prior art, the present invention provides a MJS pile body quality detection device for complex geological conditions, which has the following beneficial effects:

[0017] 1. The MJS construction pile body quality detection device used in complex geological conditions, during the process of the construction pile being lowered, the scraper bucket is kept in a state of contact with the outer side of the construction pile under the action of the sliding rod and the first spring, and then during the process of the construction pile being lowered, the impurities such as soil and concrete caked on the construction pile are scraped off and dropped into the scraper bucket, and the soil and concrete caked on the construction pile can be automatically cleaned in advance, so as to ensure that the accuracy of the detection result is improved when the construction pile is tested for verticality quality.

[0018] 2. The MJS pile body quality detection device for complex geological conditions uses the elastic force of the first spring on the sliding rod to keep the roller on the second U-shaped plate in close contact with the pile. When the pile moves downward, the friction groove on the roller causes the roller to rotate. When the roller rotates, the first rotating rod is driven to rotate synchronously through the first synchronous belt. Then, under the action of the second synchronous belt, the first rotating rod rotates while driving the second rotating rod to rotate, thereby driving the disc to rotate at the same time, causing the threaded rod to rotate with it. The threaded rod drives the T-shaped slider on the surface to rotate, and at the same time drives the fixed rod on the surface to rotate, so that the push rod slides back and forth on the inclined plate. The rubber hammers on both sides of the pile are repeatedly struck to make the pile vibrate, and the pile can overcome the resistance of the soil layer encountered in the process of inserting the pile downward, which helps to make the pile easier to descend to a predetermined position, thereby helping to improve the inspection efficiency of the pile. At the same time, when the pile vibrates, impurities such as soil agglomerated on the pile can be vibrated and fall off, thereby reducing the adhesion of impurities such as soil on the pile and loosening them in advance, which helps to make the scraping bucket scrape more smoothly, thereby helping to improve the inspection efficiency of the pile.

[0019] 3. The MJS pile body quality inspection device used for complex geological conditions controls the T-shaped slider to slide on the threaded rod by turning the hand wheel on the threaded rod. When the T-shaped slider slides, it drives the fixed rod and the connecting rod to slide at the same time, changes the reciprocating distance of the push rod on the inclined plate, and then can adjust the reciprocating distance of the rubber hammer, so that it can knock on the surface of the pile with different preset values.

[0020] 4. The MJS pile body quality detection device for complex geological conditions drives the third rotating rod to rotate while the disc rotates, thereby driving the half gear to rotate and meshing with the tooth groove inside the rectangular frame, so that the rectangular frame slides up and down reciprocatingly. The downward sliding of the rectangular frame drives the second L-shaped plate downward to contact with the contact plate, and the contact plate drives the vertical rod to slide downward, so that the vertical rod drives the piston plate at the bottom to slide downward, and at the same time compresses the third spring. The third spring can make the contact plate drive the vertical rod to automatically reset upward, and then squeeze the water inside the sealing cylinder into the spray plate through the water inlet pipe, and then spray mist water from the spray plate to spray dust above the scraper bucket. When the scraper bucket scrapes away impurities such as agglomerated soil and concrete on the method pile, and when the rubber hammer strikes the method pile to generate vibration, the dust generated above the scraper bucket is sprayed to reduce dust, which can prevent the dust from being inhaled into the body of the staff and help protect the health of the staff.

[0021] 5. The MJS pile body quality detection device used in complex geological conditions can adjust the height of the support feet by four sets of hydraulic rods at the bottom of the support frame. Even under complex geological conditions, the support frame can be kept horizontal, so that the pile can be stably detected under complex geological conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0040] Example 1: Reference Figure 1-Figure 15 The MJS pile body quality detection device for complex geological conditions includes a support frame 1 and a method pile 2 arranged on the support frame 1, and also includes: an insertion hole 4, which is arranged at the bottom of the support frame 1, and verticality detection components 3 are arranged in sequence around the insertion hole 4; a fixed plate 5, which is fixedly connected to both sides of the support frame 1, and a sliding rod 6 is slidably connected to the fixed plate 5, and the end of the sliding rod 6 away from the fixed plate 5 is fixedly connected to a scraper bucket 7, and the end of the sliding rod 6 away from the scraper bucket 7 is fixedly connected to a first limit block 8; a first spring 9, which is sleeved on the sliding rod 6, and the two ends of the first spring 9 are respectively against the fixed plate 5 and the scraper bucket 7.

[0041] In the present invention, when the construction method pile 2 is inserted into the insertion hole 4, the construction method pile 2 is hoisted, and then the verticality of the construction method pile 2 when inserted is quality inspected by the verticality detection component 3, and then the verticality of the construction method pile 2 is adjusted. At the same time, during the descent of the construction method pile 2, the scraper bucket 7 is under the action of the sliding rod 6 and the first spring 9, so that the scraper bucket 7 and the outer side of the construction method pile 2 are kept in a state of being in contact with each other, and then during the descent of the construction method pile 2, the impurities such as the agglomerated soil and concrete on the construction method pile 2 will be scraped off and fall into the interior of the scraper bucket 7, so that the construction method pile 2 can be automatically cleaned in advance, thereby ensuring the accuracy of the detection result when the construction method pile 2 is subjected to the verticality quality inspection and reducing the detection error.

[0042] Example 2: Reference Figure 1-Figure 14 , which is basically the same as the first embodiment, and further, the verticality detection component 3 includes four groups of cylinders 301 and a support plate 10 which are sequentially arranged around the insertion hole 4, the bottom of the support plate 10 is fixedly connected to the support frame 1, the cylinder 301 is fixedly connected to the support plate 10, and the output ends of the four groups of cylinders 301 are fixedly connected to a mounting plate 302, and a placement hole 303 is opened on the surface of the mounting plate 302.

[0043] A moving rod 304 runs through the placement hole 303 , and the moving rod 304 is slidably connected to the placement hole 303 and the mounting plate 302 . One end of the moving rod 304 is fixedly connected to a first U-shaped plate 305 , and the first U-shaped plate 305 is rotatably connected to a first guide wheel 306 .

[0044] The other end of the moving rod 304 is fixedly connected to the second limit block 307, and the surface of the moving rod 304 is sleeved with a second spring 308. The two ends of the second spring 308 are respectively against the placement hole 303 and the first U-shaped plate 305. The surface of the mounting plate 302 close to the cylinder 301 is fixedly connected to the first L-shaped plate 14, and the surface of the first L-shaped plate 14 is fixedly installed with a pressure sensor 11.

[0045] In the present invention, when the verticality detection is performed, the cylinder 301 is started to drive the mounting plate 302 and the moving rod 304 to move, and the moving rod 304 drives the first U-shaped plate 305 to move, so that the first guide wheel 306 contacts the construction method pile 2, and then the moving rod 304 compresses the second spring 308 to slide in the opposite direction of the movement of the mounting plate 302, and drives the second limit block 307 to move. When the construction method pile 2 is in a vertical state, the two second limit blocks 307 are in the same straight line. When the construction method pile 2 is tilted, one of the second limit blocks 307 will contact the pressure sensor 11 (the pressure sensor 11 is a prior art and is one of the sensors of the pressure sensor 11). Then the pressure sensor 11 sends a signal to the staff to inform the staff that the construction method pile 2 is tilted. Subsequently, the staff adjusts the verticality of the construction method pile 2 to detect the verticality of the construction method pile 2 when it is inserted.

[0046] Example 3: Reference Figure 1-Figure 15 , which is basically the same as the first embodiment, and further, a second U-shaped plate 12 is fixedly connected to the surface of the sliding rod 6, a roller 13 is rotatably connected to the second U-shaped plate 12, and a friction groove is provided on the surface of the roller 13.

[0047] In the present invention, the elastic force of the first spring 9 on the sliding rod 6 is used to keep the roller 13 on the second U-shaped plate 12 in close contact with the construction pile 2. During the downward movement of the construction pile 2, the friction groove on the roller 13 causes the roller 13 to rotate. The roller 13 can also guide the sliding of the construction pile 2 during its descent, which helps to make the verticality detection of the construction pile 2 more stable.

[0048] A first bearing plate 15 is fixedly connected to the surface of the fixed plate 5 near the inside of the support frame 1, and a first rotating rod 16 is rotatably connected to the surface of the first bearing plate 15. A first synchronous belt 17 is transmission-connected between the first rotating rod 16 and the roller 13. Through holes corresponding to the first synchronous belt 17 are provided on the second U-shaped plate 12 and the scraper bucket 7. A second bearing plate 18 is fixedly connected to the upper part of the support frame 1, and a second rotating rod 19 is rotatably connected to the surface of the second bearing plate 18. A second synchronous belt 20 is transmission-connected between the second rotating rod 19 and the first rotating rod 16, and a disc 21 is fixedly connected to the end of the second rotating rod 19 away from the second bearing plate 18.

[0049] In the present invention, the first bearing plate 15 can support the first rotating rod 16. When the roller 13 rotates, the first synchronous belt 17 can drive the first rotating rod 16 to rotate synchronously. Then, under the action of the second synchronous belt 20, the first rotating rod 16 rotates while driving the second rotating rod 19 to rotate, thereby driving the disc 21 to rotate simultaneously.

[0050] A rotating groove 22 is provided on the top surface of the disc 21, and a threaded rod 23 is rotatably connected to the bottom inner wall of the rotating groove 22. A handwheel 24 is fixedly connected to the top surface of the threaded rod 23. A T-shaped slider 25 penetrates the surface of the threaded rod 23. The T-shaped slider 25 is threadedly connected to the threaded rod 23. The T-shaped slider 25 penetrates the rotating groove 22 and is slidably connected to the rotating groove 22. A fixed rod 26 is fixedly connected to the surface of one end of the T-shaped slider 25 away from the threaded rod 23, and a connecting rod 27 is rotatably connected to the surface of the fixed rod 26.

[0051] An inclined plate 28 is fixedly connected to the surface of the fixed plate 5 near the inside of the support frame 1, and a push rod 29 penetrates the end surface of the inclined plate 28 away from the fixed plate 5. The push rod 29 is slidably connected to the inclined plate 28, one end of the push rod 29 is hinged to the connecting rod 27, and the other end of the push rod 29 is fixedly connected to a rubber hammer 30. A third rotating rod 31 is fixedly connected to the side of the disc 21 away from the second rotating rod 19, and a half gear 32 is fixedly connected to the third rotating rod 31. A slide rail 33 is fixedly connected to the surface of the fixed plate 5 near the inside of the support frame 1.

[0052] In the present invention, when the disc 21 rotates, the threaded rod 23 inside the rotating groove 22 is driven to rotate at the same time, and the threaded rod 23 drives the T-shaped slider 25 on the surface to rotate, and at the same time drives the fixed rod 26 on the surface to rotate, and then under the action of the inclined plate 28 supporting the limiting guide of the push rod 29, when the fixed rod 26 rotates, it drives the connecting rod 27 to rotate, so that the push rod 29 slides back and forth on the inclined plate 28, and then drives the rubber hammer 30 to repeatedly hit the surface of the construction method pile 2, so that the construction method pile 2 vibrates during the descent process. The repeated hitting of the rubber hammers 30 on both sides of the construction method pile 2 causes it to vibrate, which can overcome the resistance of the soil layer encountered during the downward insertion of the construction method pile 2, which helps to make the construction method pile 2 easier to descend to a predetermined position, thereby helping to improve The detection efficiency of the construction pile 2 is improved; at the same time, when the construction pile 2 vibrates, the impurities such as soil lumps on the construction pile 2 can be vibrated and dropped, thereby reducing the adhesion of impurities such as soil on the construction pile 2 and loosening them in advance, which helps to make the scraping bucket 7 scrape more smoothly, thereby helping to improve the detection efficiency of the construction pile 2; when the construction pile 2 greater than the preset value is to be detected, it is only necessary to turn the hand wheel 24 on the threaded rod 23 to control the T-shaped slider 25 to slide on the threaded rod 23. When the T-shaped slider 25 slides, it also drives the fixed rod 26 and the connecting rod 27 to slide, changing the reciprocating distance of the push rod 29 on the inclined plate 28, thereby adjusting the reciprocating distance of the rubber hammer 30, so that it can knock on the surface of the construction pile 2 with different preset values.

[0053] Example 4: Reference Figure 1-Figure 15, which is basically the same as the first embodiment, and further, a second L-shaped plate 34 is slidably connected inside the slide rail 33, a rectangular frame 35 is fixedly connected to the top surface of the second L-shaped plate 34, and tooth grooves 36 corresponding to the half gear 32 are opened on the inner walls of both sides of the rectangular frame 35, and a third L-shaped connecting plate 37 is fixedly connected to the bottom surface of the slide rail 33, and a sealing cylinder 38 is fixedly connected to the bottom surface of the third L-shaped connecting plate 37, and the internal piston of the sealing cylinder 38 is connected to a piston plate 39, and a vertical rod 40 is fixedly connected to the top of the piston plate 39, and the vertical rod 40 passes through the sealing cylinder 38 and is slidably connected to the sealing cylinder 38, and a contact plate 41 is fixedly connected to the top of the vertical rod 40, and a third spring 42 is sleeved on the surface of the vertical rod 40, and the two ends of the third spring 42 are respectively against the contact plate 41 and the sealing cylinder 38.

[0054] When the semi-gear 32 rotates, it will mesh with the tooth grooves 36 inside the rectangular frame 35, so that the rectangular frame 35 can slide back and forth up and down. When the rectangular frame 35 slides downward, it will drive the second L-shaped plate 34 downward to contact with the contact plate 41, and make the contact plate 41 drive the vertical rod 40 downward to slide, so that the vertical rod 40 drives the piston plate 39 at the bottom to slide downward and make a piston movement in the sealing cylinder 38; when the contact plate 41 drives the vertical rod 40 downward to move, the third spring 42 will be compressed. When the rectangular frame 35 drives the second L-shaped plate 34 to move upward, it will no longer contact with the contact plate 41. The third spring 42 can make the contact plate 41 drive the vertical rod 40 to automatically reset upward.

[0055] A fourth L-shaped connecting plate 43 is fixedly connected to the bottom of the fixed plate 5, a water bucket 44 is fixedly connected to one end of the fourth L-shaped connecting plate 43 away from the fixed plate 5, a water suction pipe 45 is fixedly connected between the water bucket 44 and the sealing cylinder 38, a spray plate 46 is fixedly connected to the top of the scraper bucket 7, a water inlet pipe 47 is fixedly connected between the spray plate 46 and the sealing cylinder 38, the water suction pipe 45 and the water inlet pipe 47 both pass through the fixed plate 5 and are fixedly connected to the fixed plate 5, four groups of hydraulic rods 48 are fixedly connected to the bottom surface of the support frame 1, the four groups of hydraulic rods 48 are sequentially arranged at the bottom of the support frame 1, and the bottoms of the four groups of hydraulic rods 48 are fixedly connected to supporting feet 49.

[0056] In the present invention, when the piston plate 39 moves downward to make a piston movement, the water inside the sealing tube 38 is squeezed out into the spray plate 46 through the water inlet pipe 47, and then the mist water is sprayed from the spray plate 46 to spray the dust above the scraper bucket 7. When the scraper bucket 7 scrapes away the impurities such as soil and concrete caked on the construction method pile 2, and when the rubber hammer 30 knocks the construction method pile 2 to make the construction method pile 2 vibrate, the spray plate 46 sprays the dust generated above the scraper bucket 7 to reduce the dust, which can prevent the dust from being inhaled into the body of the workers, helping to protect the health of the workers. Then, during the continuous descent of the construction method pile 2, the rectangular frame 35 continues to slide up and down, and the resistance plate 41 moves upward. When resetting, the piston plate 39 is driven to reset upward, so that the sealing cylinder 38 sucks water from the water bucket 44 through the water suction pipe 45, and then enters the spray plate 46 from the water inlet pipe 47 and sprays it out again, and this reciprocating process can enable the spray plate 46 to spray repeatedly to reduce dust; it should be noted that a one-way valve is installed in the water inlet pipe 47 and the water suction pipe 45, the purpose of which is to prevent water from being sucked in from the water inlet pipe 47 when absorbing water, and from being squeezed out from the water suction pipe 45 when squeezing out water; the four groups of hydraulic rods 48 at the bottom of the support frame 1 can adjust the arbitrary height of the support foot 49, so that the support frame 1 can be kept in a horizontal state even under complex geological conditions, so that the construction pile 2 can also perform stable detection under complex geological conditions.

[0057] In actual use, refer to Fig.15 , the rectangular frame 35 is set longer, and when the half gear 32 engages with the tooth groove 36 on the right side of the rectangular frame 35, under the action of gravity, the rectangular frame 35 will move downward for a distance, and then the half gear 32 will begin to engage with the tooth groove 36 on the left side of the rectangular frame 35. Therefore, here, the rectangular frame 35 and the tooth groove 36 are set longer to avoid the half gear 32 from contacting the top inner wall of the rectangular frame 35 during rotation and getting stuck, and the stroke of the slide rail 33 is sufficient to move the second L-shaped plate 34, which can ensure the continuity of the operation. It should be noted that even if the rectangular frame 35 moves downward under the above-mentioned gravity, it will only move to abut against the contact plate 41 at most, which will not affect the normal use of this application.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
