Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of pile foundation detection, in particular to a bridge pile foundation detection device. Background Art
[0002] The pile foundation of a bridge is composed of many piles driven or sunk into the soil and a cap connected to the top of the piles. Among them, cast-in-place piles are a type of bridge pile foundation. First, pile holes are made in the soil by hand or machine, and then the pile body steel cage is placed in the pile hole, and concrete is poured into the hole to form the pile foundation.
[0003] Bridge pile foundations are the foundation of a bridge. The quality of the pile foundations is directly related to the safety and durability of the bridge. If there are defects in the pile foundations, it may cause uneven settlement, tilting, or even collapse of the bridge. Therefore, it is necessary to ensure the quality of the pile foundations through testing. The usual testing method for bridge pile foundations is to use ultrasonic feedback and sensors to judge the integrity of the pile body based on the characteristics of the signal. If defects are found in the pile foundation itself or there are doubts about the test results, coring can be used as a further verification method.
[0004] However, the coring method usually uses a bench water drill to drill and coring. Before drilling and coring, the bench water drill first needs to set an anchor point on the bridge pile foundation to fix the bench water drill, and then fix the bench water drill on the anchor point to start drilling and coring. The operation steps of drilling and coring in this way are complicated when installing the equipment, and when sampling multiple positions of a pile foundation, multiple fixations are required, which affects the sampling efficiency and also causes more damage to the bridge pile foundation.

DETAILED DESCRIPTION
[0035] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0036] like Figure 1 As shown, a bridge pile foundation detection device includes a track mechanism 1 arranged on the bridge pile foundation, and an electric slide 2 is slidably connected to the track mechanism 1. The detection device also includes an adjustment mechanism 3 for adjusting the sampling position, and the adjustment mechanism 3 is arranged on the electric slide 2. The detection device also includes a sampling mechanism 4 jointly arranged on the electric slide 2 and the adjustment mechanism 3.
[0037] like Figure 1 、 Figure 2 and Figure 3 As shown, the track mechanism 1 includes an arcuate base 11 and a straight base 12. The two arcuate bases 11 are spliced together by the straight base 12. The outer sides of the arcuate base 11 and the straight base 12 are fixedly connected with a sliding track 13. A limiting member 14 is provided on the arcuate base 11. Four arcuate bases 11 and multiple straight bases 12 can be spliced into a ring base suitable for different types of bridge pile foundations.
[0038] like Figure 2 and Figure 5As shown, the two end surfaces of the arc base 11 are respectively provided with a slot and a fixedly connected pin, and the two end surfaces of the straight base 12 are also respectively provided with a slot and a fixedly connected pin. The size of the slot on the arc base 11 is adapted to the size of the pin on the straight base 12 and is snap-fitted. When snapping the pin and the slot, the slot is placed above the pin and kept in a position that overlaps with the pin in the vertical direction. Then, the slot is moved downward and the pin is snapped into the inside of the slot. At this time, the pin and the slot cooperate to perform a circumferential limiting connection on the arc base 11 and the straight base 12.
[0039] In specific use, when sampling the rounded rectangular bridge pile foundation, first, the four arc bases 11 are evenly distributed in the circumferential direction, and the same number of straight bases 12 are clamped between the two arc bases 11 opposite to each other in the front and back, and the same number of straight bases 12 are clamped between the two arc bases 11 opposite to each other in the left and right, and the number of straight bases 12 clamped between the two arc bases 11 opposite to each other in the front and back is different from the number of straight bases 12 clamped between the two arc bases 11 opposite to each other in the left and right. The straight bases 12 are clamped between the opposite surfaces of the two arc bases 11 through the pins and slots on the adjacent surfaces of the arc bases 11, and multiple arc bases 11 and multiple straight bases 12 are assembled into an annular base that is suitable for the rounded rectangular bridge pile foundation. At the same time, the sliding tracks 13 on all the arc bases 11 and the straight bases 12 are jointly enclosed to form an annular track that is suitable for the rounded rectangular bridge pile foundation (such as Figure 4 shown).
[0040] Then install the electric slide 2 on the sliding rail 13. After the assembly is completed, the annular base is placed on it from the top of the bridge pile foundation through the external lifting equipment through the limit piece 14 and the lifting ring on the straight base 12. Then, it is moved down to a suitable position, and then the annular base is fixed on the bridge pile foundation through the limit piece 14 on the arc base 11, and the lifting of the arc base 11 and the straight base 12 by the external lifting equipment is cancelled.
[0041] like Figure 1 、 Figure 5 and Figure 6As shown, the limiting member 14 includes a first hydraulic telescopic cylinder 141 fixedly connected to the upper surface of the arc-shaped base 11 through a connecting sleeve, and the telescopic end of the first hydraulic telescopic cylinder 141 is hinged with a positioning plate 142, and the positioning plate 142 is slidably connected to a plurality of evenly distributed auxiliary pins 143 on a surface away from the first hydraulic telescopic cylinder 141. The auxiliary pins 143 pass through the interior of the positioning plate 142, and a connecting spring (not shown in the figure) is provided between the end of the auxiliary pin 143 close to the positioning plate 142 and the positioning plate 142. The bottom end of the positioning plate 142 is fixedly connected to a sliding adjustment sleeve 145, and a second hydraulic telescopic cylinder 144 is hinged on the sliding adjustment sleeve 145. The end of the second hydraulic telescopic cylinder 144 away from the sliding adjustment sleeve 145 is hinged to the lower surface of the track mechanism 1, and a lifting ring is provided at the center position of the mounting sleeve on the first hydraulic telescopic cylinder 141 and the upper surface of the linear base 12.
[0042] During specific use, when the annular base is fixed on the bridge pile foundation by the limit member 14, when the annular base moves to the specified position, the first hydraulic telescopic cylinder 141 is extended first, pushing the positioning plate 142 to move in the direction close to the bridge pile foundation. At this time, the auxiliary clamping pin 143 on the positioning plate 142 is in contact with the surface of the bridge pile foundation. As the positioning plate 142 is continuously pushed, the auxiliary clamping pin 143 is subjected to the resistance of the bridge pile foundation and slides toward the inside of the positioning plate 142. At the same time, the connecting spring is compressed. Under the action of the elastic force of the connecting spring itself, the auxiliary clamping pin 143 is pressed against the surface of the bridge pile foundation. By setting up multiple evenly distributed auxiliary pins 143, the contact area between the positioning plate 142 and the arc surface of the bridge pile foundation can be increased, and the friction between the positioning plate 142 and the bridge pile foundation can be improved. When the first hydraulic telescopic cylinder 141 pushes the positioning plate 142 against the bridge pile foundation, the second hydraulic telescopic cylinder 144 is extended to push the bottom end of the positioning plate 142 to be synchronously pressed against the bridge pile foundation. At this time, the four corners of the annular base formed by the arc base 11 and the straight base 12 are subjected to a force away from the bridge pile foundation, and the closed loop of the annular base is used to firmly fix the annular base on the bridge pile foundation.
[0043] like Figure 1 and Figure 7 As shown, the adjustment mechanism 3 includes a first drive motor 34 embedded in the center of the upper surface of the electric slide 2, and a screw rod 32 is fixedly connected to the output shaft of the first drive motor 34. The upper surface of the electric slide 2 slides up and down and is penetrated by two groups of left-right symmetrical limit slides 33. The bottom ends of the two groups of limit slides 33 penetrate to the lower surface of the electric slide 2 and are fixedly connected to a fixed block 35. The top ends of the two groups of limit slides 33 are fixedly connected to the limit slide 31. The screw rod 32 penetrates the limit slide 31 up and down and is threadedly connected to the limit slide 31.
[0044] During specific use, after the annular base is fixed, the electric slide 2 slides on the sliding track 13, driving the sampling mechanism 4 to move above the sampling position, and then the first drive motor 34 drives the screw rod 32 to rotate. At this time, the screw rod 32 rotates on the limiting slide 31, and the circumferential direction of the limiting slide 31 is limited by four limiting slides 33. The limiting slide 31 pushes the limiting slide 33 to move downward on the electric slide 2, and the limiting slide 33 pushes the fixed block 35 to move downward. After the fixed block 35 drives the sampling mechanism 4 to move downward to the sampling position below the water surface, the rotation of the first drive motor 34 is stopped, and then sampling is started through the sampling mechanism 4.
[0045] like Figure 1 and Figure 8 As shown, the sampling mechanism 4 includes two front-to-back symmetrical support stands 44 fixedly connected to the upper surface of the electric slide 2, and the top ends of the two support stands 44 are connected to a connecting slide 45 that slides along the front-to-back direction. A sampling part 42 is commonly provided on the support stand 41 and the connecting slide 45, and an adjusting part 43 is commonly provided on the support stand 41, the sampling part 42 and the connecting slide 45.
[0046] like Figure 8 、 Figure 9 and Figure 10 As shown, the sampling member 42 includes two left-right symmetrical connecting sliders 422 that are slidably connected to the support frame 41 along the front-back direction, and a first transmission box 421 is fixedly connected between the opposite surfaces of the two connecting sliders 422. The upper surface of the first transmission box 421 is rotatably connected to the first spline shaft 424, and the upper surface of the first spline shaft 424 is slidably connected to the first spline shaft cylinder 423 along the up-down direction. The upper surface of the connecting slide 45 is fixedly installed with a second drive motor 426, and the output shaft of the second drive motor 426 passes through the connecting slide 45. The lower surface of the sliding plate 45 is fixedly connected to the top of the first spline shaft cylinder 423, and the rear surface of the first transmission box 421 is rotatably connected to the drill bit 425. The front and rear surfaces of the fixed block 35 are provided with through holes adapted to the drill bit 425. The rear end of the drill bit 425 passes through the through hole on the fixed block 35 and rotates with the fixed block 35 and is slidably connected in the front and rear directions. The first spline shaft 424 and the drill bit 425 at one end close to the first transmission box 421 are both inserted into the interior of the first transmission box 421 and are connected by a bevel gear transmission (such as Figure 11 shown).
[0047] like Figure 8 、 Figure 9 and Figure 10As shown, the adjusting member 43 includes a second transmission box 433 fixedly connected to the upper surface of the left connecting slider 422, the left side of the second transmission box 433 is rotatably connected to a circular gear 434, the left side of the support frame 41 is fixedly connected to a rack 435, the circular gear 434 is engaged with the rack 435, the upper surface of the second transmission box 433 is rotatably connected to a second spline shaft 431, the outer surface of the second spline shaft 431 is slidably connected to a second spline shaft cylinder 432 in the up and down directions, and the left side of the connecting slide 45 is fixedly connected to L shaped connecting plate 436, the top of the vertical section of the L-shaped connecting plate 436 is fixedly mounted with a third drive motor 437, the top of the second spline shaft cylinder 432 passes through the upper surface of the horizontal section of the L-shaped connecting plate 436 in the up-down direction and is fixedly connected to the bottom end of the output shaft of the third drive motor 437, the top of the second spline shaft cylinder 432 is provided with a rotating handle, the second spline shaft 431 and the end of the circular gear 434 close to the second transmission box 433 are both passed through the interior of the second transmission box 433, and are connected by a bevel gear transmission (such as Figure 12 shown).
[0048] During specific use, when the fixed block 35 drives the sampling mechanism 4 to move downward, the support frame 41 moves downward with the fixed block 35. In the process of the support frame 41 and the fixed block 35 driving the drill bit 425 to move to the sampling position, the first transmission box 421 and the second transmission box 433 move synchronously with the support frame 41, and at the same time drive the first spline shaft 424 to slide downward inside the first spline shaft cylinder 423, and the second spline shaft 431 to slide downward inside the second spline shaft cylinder 432. When the drill bit 425 moves to the sampling position, the second drive motor 426 rotates through the first spline shaft cylinder 423 to drive the first spline shaft 424 to move in the first transmission box. The bottom end of the first transmission box 421 drives the drill bit 425 to rotate on the first transmission box 421 through a bevel gear transmission, and the sampling work starts. While the drill bit 425 rotates, the third drive motor 437 drives the second spline shaft 431 to rotate on the second transmission box 433 through the second spline shaft cylinder 432, and the bottom end of the second spline shaft 431 drives the circular gear 434 to rotate on the second transmission box 433 through a bevel gear transmission. When the circular gear 434 rotates, it cooperates with the rack 435 to drive the connecting slider 422 to slide backward on the support frame 41, pushing the drill bit 425 to drill holes on the bridge pile foundation for sampling.
[0049] When the drill bit 425 completes sampling, the second drive motor 426 is stopped to drive the drill bit 425 to rotate, and the third drive motor 437 starts to rotate in the opposite direction, driving the circular gear 434 to rotate in the opposite direction on the rack 435, so that the drill bit 425 moves in the opposite direction away from the bridge pile foundation, separating the drill bit 425 from the bridge pile foundation. When multiple sampling is required on the bridge pile foundation, the staff is transported to the sampling position by the external lifting platform equipment to take out the sample inside the drill bit 425 and save it, and then repeat the above steps to perform the next sampling work After all the sampling is completed, the lifting ring on the limit piece 14 and the linear base 12 is reconnected through the external lifting equipment, and then the first hydraulic telescopic cylinder 141 and the positioning plate 142 are synchronously contracted to cancel the thrust on the positioning plate 142. At this time, the positioning plate 142 gradually moves away from the bridge pile foundation, and the annular base is no longer subjected to thrust. The annular base is removed from the bridge pile foundation through the external lifting equipment, and the collected samples are stored independently and marked, and then sent to the laboratory for further verification of the locations where the quality of the bridge pile foundation is questionable.
[0050] When only one sampling is required on a bridge pile foundation, the above steps of removing the annular base are repeated first. After the annular base is removed from the bridge pile foundation, the sample is taken out from the inside of the drill bit 425. The sample is then stored and marked independently and sent to the laboratory for further verification of the location where the bridge pile foundation quality is in doubt.
[0051] It should be noted that when sampling on a cylindrical bridge pile foundation, first, four arc-shaped bases 11 are evenly distributed circumferentially. According to the size of the cylindrical bridge pile foundation, the same number of straight bases 12 are clamped between two adjacent arc-shaped bases 11. All the arc-shaped bases 11 and the straight bases 12 form a ring base that is suitable for the cylindrical bridge pile foundation. The sliding tracks 13 on the arc-shaped bases 11 and the straight bases 12 are combined to form a ring track that is suitable for the cylindrical bridge pile foundation. Then, the above steps are repeated to perform sampling on the cylindrical bridge pile foundation (such as Figure 13 shown).
[0052] Working principle: When in use, first, according to the shape of the bridge pile foundation, four arc-shaped bases 11 are evenly distributed in a circle, and a suitable number of straight-line bases 12 are matched to form a ring-shaped base around the bridge pile foundation. At the same time, the sliding tracks 13 on the arc-shaped base 11 and the straight-line base 12 are combined into a ring track. With the external lifting equipment, the base is lifted to the position of the bridge pile foundation at a certain distance from the water surface. The arc-shaped base 11 and the straight-line base 12 are fixed on the bridge pile foundation through the limiter 14, and then the sampling piece 42 is adjusted by sliding circumferentially on the sliding track 13 through the electric slide 2. The sampling part 42 is pushed downward into the water to the sampling position through the adjusting mechanism 3. Then the staff pushes the sampling part 42 toward the bridge pile foundation through the adjusting member 43 and starts sampling on the bridge pile foundation. When the sampling is completed, the sampling part 42 is pushed back to its original position through the adjusting member 43. At the same time, the adjusting mechanism 3 drives the sampling part 42 to move upward out of the water. After that, the staff removes the sample from the sampling part 42 and sends the sample to the laboratory for testing, thereby completing further verification of the position where the quality of the bridge pile foundation is in doubt.
