Description

Technical Field

[0001] This application relates to the field of cast-in-place pile technology, specifically to a device for measuring the amount of concrete used in cast-in-place piles. Background Technology

[0002] In construction engineering, cast-in-place piles are a common type of foundation. They are made by pouring concrete or reinforced concrete into the pile. Cast-in-place piles are an important component of load-bearing structures and are commonly used in the foundations of high-rise buildings, long-span bridges, tunnels, docks, and airports. By providing strong load-bearing capacity, they ensure the stability and safety of the entire structure. When pouring concrete into the cast-in-place piles, measuring devices are needed to detect the amount of concrete used.

[0003] An existing patent (publication number: CN221052693U) discloses a device for measuring the amount of concrete used in cast-in-place piles, including a fixed frame and a cast-in-place pile pipe. A transmitter and a control terminal are fixed to the upper left side of the fixed frame. A take-up and release wheel is provided on the inner side of the fixed frame, and a cable is fixed on the take-up and release wheel. The cable extends downward to the inside of the cast-in-place pile pipe, and a counterweight ball is fixed to the lower end of the cable. A pressure sensor is fixed to the lower part of the cable. The pressure sensor and the counterweight ball are arranged continuously, and the pressure sensor, transmitter, and control terminal are electrically connected. In this device for measuring the amount of concrete used in cast-in-place piles, the pressure sensor can sense the pressure changes in the air and inside the concrete, thereby sending a signal to the control terminal. The transmitter and receiver work together to calculate the number of rotations of the wheel, thereby calculating the length of the cable extension. Combined with the length and cross-sectional area of ​​the cast-in-place pile pipe, the amount of concrete used can be calculated. The lower end of the positioning pile is conical to facilitate the counterweight ball to extend into the concrete.

[0004] When using the above solution, the cable is wound around the take-up and release wheels multiple times during the winding process. This results in different winding lengths of the cable due to the multiple rotations of the take-up and release wheels, making it impossible to accurately calculate the winding length of the cable based on the number of rotations of the take-up and release wheels. This affects the accuracy of concrete usage measurement. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a device for measuring the concrete usage of cast-in-place piles. This device features a fixed detection roller that can pull the cable by the same length in one rotation, ensuring that multiple rotations of the detection roller result in the same pull length. It allows for precise calculation of the cable pull length based on the number of rotations of the detection roller, improving the accuracy of concrete usage measurement. This solves the problem that during operation, the cable often winds multiple times on the take-up and release wheels, resulting in inconsistent cable winding lengths due to multiple rotations of the take-up and release wheels. Consequently, the accuracy of concrete usage measurement is compromised by the inability to accurately calculate the cable winding length based on the number of rotations of the take-up and release wheels.

[0006] To achieve the aforementioned goal of fixing the length of cable pull with one revolution of the detection roller, ensuring that multiple revolutions of the detection roller result in the same pull on the cable, and accurately calculating the pull length based on the number of revolutions of the detection roller, thereby improving the accuracy of concrete usage measurement, this application provides the following technical solution: A concrete usage measurement device for cast-in-place piles, comprising a detection roller, the two ends of which are rotatably mounted on one end of two support frames via rotating shafts, a cable wound around the outer surface of the middle portion of the detection roller, the cable only wound once around the outer surface of the middle portion of the detection roller, and an anti-slip layer provided on the outer surface of the middle portion of the detection roller. One end of the cable is set on the outer surface of the middle part of the take-up roller, and the other end of the cable is set with a counterweight. The two ends of the take-up roller are rotatably mounted on the top of two support frames via rotating frames. A belt is sleeved on the rotating rod at one end of the take-up roller via a pulley. The inner side of one end of the belt is sleeved on the output shaft of the first motor via a pulley. The bottom of the first motor is set on the top of the corresponding support frame via a fixing block. A receiver is set on the inner side of the guard plate at one end of the detection roller. A through hole is opened on the guard plate at the other end of the detection roller corresponding to the position of the receiver. The receiver is electrically connected to the transmitter. The transmitter is set on the top of the support frame corresponding to the signal receiving direction of the receiver.

[0007] The above scheme involves winding the cable only once around the outer surface of the middle section of the detection roller. When the cable is pulled up by the take-up roller to a length corresponding to the circumference of the detection roller, it will cause the detection roller to rotate once. The pulling length of the cable can be calculated based on the number of rotations of the detection roller. This achieves the goal of fixing the pulling length of the cable for one rotation of the detection roller, ensuring that multiple rotations of the detection roller can achieve the same pulling length of the cable. The pulling length of the cable can be accurately calculated based on the number of rotations of the detection roller, thus improving the accuracy of concrete usage measurement.

[0008] Furthermore, one end of each of the two support frames is fixedly connected to both ends of the fixed plate.

[0009] The above solution allows for the fixing of the position between the two support frames using a fixing plate, thereby improving the stability of the detection roller when it rotates between the two support frames.

[0010] Furthermore, the middle of the cable is located between two extrusion rollers, and the two extrusion rollers are rotatably mounted on one end of two push rods via a rotating frame.

[0011] The above scheme uses two extrusion rollers to squeeze the cable and pull the cable below the detection roller. This allows the cable to be tightly wrapped around the outer surface of the middle part of the detection roller during winding and lifting, so that the cable can stably drive the detection roller to rotate during lifting.

[0012] Furthermore, the outer surface of the middle part of the extrusion roller is concave, and the shape of the outer surface of the middle part of the extrusion roller is adapted to the outer surface of the middle part of the cable.

[0013] The above scheme allows the two extrusion rollers to be stably and tightly attached to both sides of the cable by the concave shape of the outer surface of the middle part of the extrusion rollers, preventing the cable from slipping out between the two extrusion rollers.

[0014] Furthermore, two limiting frames are provided at the bottom of one end of the two support frames via a fixing rod, and the inner walls of the two limiting frames are fitted onto the outer surface of the middle part of the two push rods.

[0015] The above solution uses two limiting frames to fix the movement trajectory of the two push rods, thereby improving the stability when the two push rods drive the two extrusion rollers to move.

[0016] Furthermore, a second motor is mounted on one side of the fixed plate via a fixing frame. A threaded rod is mounted on one end of the second motor. The outer surface of the middle part of the threaded rod is threaded to the inner wall of the middle part of the connecting plate. A telescopic rod is mounted on one side of the connecting plate. One end of the telescopic rod is mounted on one side of the push plate. Two swing rods are hinged to both ends of the push plate via a hinge frame. The inner walls of one end of the two swing rods are hinged to one side of one end of the two push rods via a hinge frame.

[0017] With the above scheme, the second motor can drive the threaded rod to rotate, which in turn drives the connecting plate to move. This, in turn, causes the connecting plate to move in conjunction with the telescopic rod, which in turn drives the push plate to move. The push plate then drives two push rods to move via two swing rods, which in turn drives the two extrusion rollers to move in different directions, thus adjusting the distance between the two extrusion rollers.

[0018] Furthermore, a spring is provided inside the telescopic rod, with one end of the spring located at one end of the telescopic inner rod and the other end of the spring located at one end of the inner wall of the telescopic outer tube.

[0019] With the above scheme, the spring can apply a pulling force to the push plate through the telescopic rod, so that the push plate can apply a pushing force to the two extrusion rollers through the two swing rods and two push rods, so that the two extrusion rollers can stably and tightly extrude the two sides of the cable.

[0020] Furthermore, the inner wall of one end of the connecting plate is slidably disposed on the outer surface of the middle part of the limiting rod, and one end of the limiting rod is disposed at the bottom of the fixing plate through a fixing bracket.

[0021] The above solution allows for the fixation of the angle of the connecting plate during movement by sliding the inner wall of one end of the connecting plate on the outer surface of the middle part of the limiting rod, thereby improving the stability of the connecting plate during movement.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This device for measuring the amount of concrete used in cast-in-place piles uses a cable that wraps around the outer surface of the middle of a detection roller once. When the cable is pulled up by a take-up roller to a length corresponding to the circumference of the detection roller, it causes the detection roller to rotate one revolution. The pulling length of the cable can be calculated based on the number of revolutions of the detection roller. This achieves the goal of fixing the pulling length of the cable for one revolution of the detection roller, ensuring that multiple revolutions of the detection roller can achieve the same pulling length of the cable. It can accurately calculate the pulling length of the cable based on the number of revolutions of the detection roller, thus improving the accuracy of concrete usage measurement.

Detailed Implementation

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Please see Figure 1 and Figure 2 This embodiment of a concrete usage measurement device for cast-in-place piles includes a detection roller 1. The two ends of the detection roller 1 are rotatably mounted on one end of two support frames 2 via rotating shafts. A cable 3 is wound around the outer surface of the middle part of the detection roller 1. The cable 3 is wound only once around the outer surface of the middle part of the detection roller 1. An anti-slip layer is provided on the outer surface of the middle part of the detection roller 1. The anti-slip layer on the outer surface of the middle part of the detection roller 1 can increase the friction between the detection roller 1 and the cable 3, so that the cable 3 can stably drive the detection roller 1 to rotate when it is pulled by the take-up roller 4.

[0033] Please see Figure 1 and Figure 2 One end of the cable 3 is set on the outer surface of the middle part of the winding roller 4, and the other end of the cable 3 is set with a counterweight 22. The two ends of the winding roller 4 are rotatably set on the top of the two support frames 2 through the rotating frame. One end of the winding roller 4 has a rotating rod with a belt 8 sleeved on it through a pulley. The inner side of one end of the belt 8 is sleeved on the output shaft of the first motor 9 through the pulley. The bottom of the first motor 9 is set on the top of the corresponding support frame 2 through a fixing block. The inner side of the guard plate of one end of the detection roller 1 is set with a receiver 5. The guard plate of the other end of the detection roller 1 has a through hole 6 at the position corresponding to the receiver 5. The receiver 5 is electrically connected to the transmitter 7. The transmitter 7 is set on the top of the support frame 2 corresponding to the signal receiving direction of the receiver 5.

[0034] Please see Figure 1 , Figure 3 and Figure 5 One end of each of the two support frames 2 is fixedly connected to both ends of the fixing plate 10. The fixing plate 10 can fix the position between the two support frames 2, thereby improving the stability of the detection roller 1 when rotating between the two support frames 2.

[0035] Please see Figure 1 , Figure 2 and Figure 3The cable 3 is located between two extrusion rollers 11. The two extrusion rollers 11 are rotatably mounted on one end of two push rods 12 via a rotating frame. The two extrusion rollers 11 work together to extrude the cable 3, which in turn pulls the cable 3 below the detection roller 1. This allows the cable 3 to be tightly wrapped around the outer surface of the middle part of the detection roller 1 during winding and lifting, so that the cable 3 can stably drive the detection roller 1 to rotate during lifting.

[0036] Please see Figure 1 , Figure 3 and Figure 5 The outer surface of the middle part of the extrusion roller 11 is concave, and the shape of the outer surface of the middle part of the extrusion roller 11 is adapted to the outer surface of the middle part of the cable 3. The concave shape of the outer surface of the middle part of the extrusion roller 11 allows the two extrusion rollers 11 to be stably and tightly attached to both sides of the cable 3, preventing the cable 3 from slipping out between the two extrusion rollers 11.

[0037] Please see Figure 1 , Figure 2 and Figure 3 Two limit frames 20 are set at the bottom of one end of the two support frames 2 by a fixed rod. The inner wall of the middle part of the two limit frames 20 is sleeved on the outer surface of the middle part of the two push rods 12. The movement trajectory of the two push rods 12 can be fixed by the two limit frames 20, thereby improving the stability when the two push rods 12 drive the two extrusion rollers 11 to move.

[0038] Please see Figure 3 , Figure 4 and Figure 5 A second motor 18 is mounted on one side of the fixed plate 10 via a fixed frame. A threaded rod 17 is mounted on one end of the second motor 18. The outer surface of the threaded rod 17 is threadedly connected to the inner wall of the middle part of the connecting plate 16. A telescopic rod 15 is mounted on one side of the connecting plate 16. One end of the telescopic rod 15 is mounted on one side of the push plate 14. Two swing rods 13 are hinged to both ends of the push plate 14 via a hinge frame. The inner wall of one end of each swing rod 13 is hinged to one side of one end of each push rod 12 via a hinge frame. The second motor 18 can drive the threaded rod 17 to rotate, causing the threaded rod 17 to move the connecting plate 16. In turn, the connecting plate 16, in conjunction with the telescopic rod 15, moves the push plate 14. The push plate 14, through the two swing rods 13, moves the two push rods 12, which in turn moves the two extrusion rollers 11 in different directions, thus adjusting the distance between the two extrusion rollers 11.

[0039] Please see Figure 4A spring 21 is installed inside the telescopic rod 15. One end of the spring 21 is located at one end of the telescopic inner rod of the telescopic rod 15, and the other end of the spring 21 is located at one end of the inner wall of the telescopic outer tube of the telescopic rod 15. The spring 21 can apply a pulling force to the push plate 14 through the telescopic rod 15, so that the push plate 14 can apply a pushing force to the two extrusion rollers 11 through the two swing rods 13 and the two push rods 12, so that the two extrusion rollers 11 can stably and tightly extrude the two sides of the cable 3.

[0040] Please see Figure 4 and Figure 5 The inner wall of one end of the connecting plate 16 is slidably disposed on the outer surface of the middle part of the limiting rod 19. One end of the limiting rod 19 is disposed at the bottom of the fixing plate 10 through a fixing bracket. The angle of the connecting plate 16 when it moves can be fixed by the inner wall of one end of the connecting plate 16 sliding on the outer surface of the middle part of the limiting rod 19, thereby improving the stability of the connecting plate 16 when it moves.

[0041] In this embodiment, a concrete usage measurement device for cast-in-place piles utilizes a cable 3 that is wound only once around the outer surface of the middle part of the detection roller 1. When the cable 3 is pulled up by the take-up roller 4 to a length corresponding to the circumference of the detection roller 1, it will cause the detection roller 1 to rotate one revolution. The lifting length of the cable 3 can be calculated based on the number of revolutions of the detection roller 1. This achieves the effect of fixing the lifting length of the cable 3 by one revolution of the detection roller 1, so that multiple revolutions of the detection roller 1 can achieve the same lifting length of the cable 3. The lifting length of the cable 3 can be accurately calculated based on the number of revolutions of the detection roller 1, thereby improving the accuracy of concrete usage measurement.

[0042] The working principle of the above embodiment is as follows: The device is placed above the position of the grouting pile, and the bottoms of the two support frames 2 are placed on the ground on both sides of the grouting pile. The second motor 18 works, driving the threaded rod 17 to rotate, causing the threaded rod 17 to drive the connecting plate 16 to move towards the push plate 14. The connecting plate 16, through the telescopic rod 15 and the spring 21, pushes the push plate 14 away from the second motor 18, causing the push plate 14 to drive the two swing rods 13 to swing. The two swing rods 13, through the two push rods 12, drive the distance between the two extrusion rollers 11 to gradually increase, causing the two extrusion rollers 11 to disengage from the cable 3. The first motor 9... The operation begins with the belt 8 driving the take-up roller 4 to release the cable 3 wound on its outer surface. The cable 3, under the weight of the counterweight 22, begins to move downwards, causing the counterweight 22 to pull the cable 3 into the concrete inside the pile until the counterweight 22 reaches the bottom of the pile. Then, the second motor 18 operates, causing the threaded rod 17 to drive the connecting plate 16 towards the second motor 18. The connecting plate 16, through the telescopic rod 15 and spring 21, drives the push plate 14 towards the second motor 18. The push plate 14 then drives the two swing rods 13 to swing, and the two swing rods 13, through the two push rods 12, drive the two extrusion rollers 11 to move. The distance between the two extrusion rollers 11 gradually decreases, causing the two extrusion rollers 11 to contact both sides of the outer surface of the cable 3. The connecting plate 16 continues to move, stretching the telescopic rod 15, which in turn stretches the spring 21. The spring 21 applies a pulling force to the push plate 14 through the telescopic rod 15, which in turn causes the two push rods 12 to apply a pushing force to the two extrusion rollers 11, making the two extrusion rollers 11 tightly adhere to both sides of the outer surface of the cable 3. The first motor 9 drives the take-up roller 4 to rotate through the belt 8, and the take-up roller 4 begins to wind up the cable 3, pulling the cable 3 upward. When the cable 3 is pulled upward, it will... The detection roller 1 rotates, which in turn drives the through hole 6 and receiver 5 to rotate. When the detection roller 1 rotates one revolution, the through hole 6 and receiver 5 will be on the same straight line as the transmitter 7. The transmitter 7 will transmit a signal to the receiver 5 through the through hole 6, so that the receiver 5 can cooperate with the transmitter 7 to count the number of revolutions of the detection roller 1 until the cable 3 and the counterweight 22 are completely pulled out of the concrete inside the cast-in-place pile. The length of the cable 3 pulled out of the concrete inside the cast-in-place pile is calculated by the number of revolutions of the detection roller 1. The amount of concrete used in the cast-in-place pile is calculated by combining the length of the cable 3 pulled out of the concrete with the diameter of the cast-in-place pile.
