Description

Technical Field

[0001] The present invention relates to the technical field of pile foundation hole forming depth measurement, and specifically relates to a simple pile foundation hole forming depth measurement tool. Background Art

[0002] Traditional pile foundation hole forming depth measurement methods usually involve inserting a tape measure into the pile hole, allowing it to sink to the bottom of the pile by its own weight, and then measuring the hole depth by reading relevant data. Such measurement methods have relatively low accuracy and are quite inconvenient to operate in complex and changeable construction environments, making it difficult to meet the requirements of modern engineering construction for high precision and high efficiency.

[0003] Chinese Patent with Publication No. CN222481358U discloses a spliced telescopic ruler for measuring the depth of a rotary drilled cast-in-place pile hole, which includes at least one telescopic ruler assembly. The telescopic ruler assembly includes an outer ruler body and an inner ruler body, and the outer ruler body and the inner ruler body are coaxially sleeved. The telescopic ruler assembly also includes a splicing structure A and a splicing structure B respectively arranged at the ends of the outer ruler body and the inner ruler body, and the splicing structure A and the splicing structure B are mutually adapted. A bayonet is arranged on one side of the outer ruler body away from the splicing structure A, and a snap button is arranged on one side of the inner ruler body away from the splicing structure B, and the snap button and the bayonet are mutually adapted.

[0004] The above patent designs a spliced telescopic ruler for measuring the depth of a rotary drilled cast-in-place pile hole to solve the problem of inaccurate measurement of the depth of the pile hole of a rotary pressed cast-in-place pile.

[0005] However, the existing technology has the following deficiencies: due to the insufficient self-weight of the tape measure, it is difficult to sink smoothly to the bottom of the hole, which seriously affects the measurement accuracy, resulting in a smaller measurement result and unable to accurately reflect the true hole depth situation. The tape measure is extremely vulnerable to mud obstruction during the falling and rising processes, and it is inconvenient to clean the mud.

[0006] Therefore, the present invention provides a simple pile foundation hole forming depth measurement tool with high precision and convenient mud cleaning. Summary of the Invention

[0007] A simple pile foundation hole forming depth measurement tool is designed to address the problems of poor measurement accuracy and inconvenient mud cleaning in the prior art.

[0008] The technical solution adopted by the present invention to solve its technical problems is: a simple pile foundation hole forming depth measurement tool, including a steel bar frame body, a rotating mechanism is arranged on the steel bar frame body. The rotating mechanism includes a round block fixedly installed on the steel bar frame body, a movable handle fixedly installed on the round block, a round shell rotatably installed on the round block, a fixed handle fixedly installed on the round shell, and a support assembly is arranged on the steel bar frame body;

[0009] The steel frame is provided with a measuring mechanism, which includes a support sleeve rotatably mounted on the steel frame, a measuring rope connected to the support sleeve, a marking line is provided on the measuring rope at intervals of one meter, and a gravity block is connected to the end of the measuring rope;

[0010] The support assembly is provided with a clamping mechanism, which includes a connecting frame provided on the support assembly, a fixing clamp fixedly mounted on the end of the connecting frame, a fastening bolt rotatably mounted on the fixing clamp, and a movable clamp threadedly mounted on the fastening bolt;

[0011] The steel frame is provided with an elastic mechanism, which includes an axis rod fixedly installed on the steel frame, a torsion spring is connected to the steel frame, the end of the torsion spring is connected to a fixed block adapted to the axis rod, a touch assembly is provided on the fixed block, and a toggle frame adapted to the measuring rope is fixedly installed on the fixed block.

[0012] Furthermore, a positioning hole is provided on the fixing handle.

[0013] Furthermore, a positioning bolt adapted to the positioning hole is threadedly mounted on the movable handle.

[0014] Furthermore, the support assembly includes a circular sleeve fixedly mounted on the steel frame, the inner side of the circular sleeve is connected to a first spring, and the end of the first spring is connected to a telescopic rod fixed to the connecting frame.

[0015] Furthermore, a rope loop adapted to the measuring rope is fixedly mounted on the end of the telescopic rod.

[0016] Furthermore, the fixed clamp and the movable clamp are adapted to the measuring rope together.

[0017] Furthermore, the trigger assembly includes a long rod fixedly mounted on the fixing block.

[0018] Furthermore, the inner wall of the end of the long rod is connected to a second spring, the end of the second spring is connected to a telescopic block adapted to the inner wall of the end of the long rod, and a touch block is fixedly mounted on the telescopic block.

[0019] Furthermore, a plurality of clamping blocks adapted to the trigger blocks are fixedly mounted on the circular shell.

[0020] Beneficial effects of the present invention:

[0021] (1) The present invention relates to a simple pile foundation hole depth measuring tool. During measurement, the movable handle is rotated to drive the steel frame to rotate through the round block, so that the steel frame loosens the measuring rope, and the gravity block uses its own gravity to drive the measuring rope to move into the hole. When the measuring rope reaches the bottom of the hole, the value corresponding to the marking line is read, and then a tape measure is used to measure the length of the measuring rope outside the marking line. The two are added together to finally obtain accurate hole depth data, thereby improving the accuracy of measurement.

[0022] (2) The present invention provides a simple pile foundation hole depth measuring tool. By reversing the movable handle, the movable handle drives the steel frame to reverse, so that the measuring rope is wound around the steel frame, thereby facilitating the storage of the measuring rope. When the measuring rope drives the gravity block to contact the rope loop, the movable handle is rotated to a position corresponding to the fixed handle, and the positioning bolt is screwed into the inner side of the positioning hole, so that the first spring uses its own elastic force to abut the gravity block through the telescopic rod and the rope loop, so that the measuring rope is tightened on the steel frame, thereby preventing the measuring rope from becoming tangled.

[0023] (3) The present invention provides a simple pile foundation hole depth measuring tool. When the gravity block drives the measuring rope to move to the bottom of the hole, the fastening bolt is screwed so that the fastening bolt drives the movable clamp to approach the fixed clamp by the thread action, so that the fixed clamp and the movable clamp cooperate with each other to clamp and fix the measuring rope. The measuring rope is moved out of the hole, and the clamping point is measured by the marking line and the tape measure to further measure the hole depth and avoid errors.

[0024] (4) The present invention relates to a simple pile foundation hole depth measuring tool. When the measuring rope is stored by rotating the movable handle, the frame drives the long rod to rotate through the shaft and the fixed block, so that the long rod drives the touch block to move through the second spring and the telescopic block, so that the touch block is engaged with multiple clamping blocks, and the long rod drives the toggle frame to toggle the measuring rope through the fixed block. When the touch block squeezes the clamping block to a certain extent, the touch block moves into the end of the long rod by squeezing the second spring, so that the touch block is separated from the clamping block, so that the torsion spring can use its own elastic force to drive the toggle frame to rotate and reset through the fixed block, and the measuring rope is toggled again, so that the mud and dust on the surface of the measuring rope can be cleaned.

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0037] like Figures 1-9As shown in the figure, a simple tool for measuring the depth of pile foundation hole formation according to the present invention includes a steel bar frame body 1. A rotating mechanism is provided on the steel bar frame body 1. The rotating mechanism includes a round block 2 fixedly installed on the steel bar frame body 1. An activity handle 3 is fixedly installed on the round block 2. A round shell 4 is rotatably installed on the round block 2. A fixed handle 5 is fixedly installed on the round shell 4. A positioning hole 10 is opened on the fixed handle 5. A positioning bolt 11 adapted to the positioning hole 10 is threadedly installed on the activity handle 3. A measuring mechanism is provided on the steel bar frame body 1. The measuring mechanism includes a support sleeve 6 rotatably installed on the steel bar frame body 1. A measuring rope 7 is connected to the support sleeve 6. Marking lines 8 are provided on the measuring rope 7 at intervals of one meter. A gravity block 9 is connected to the end of the measuring rope 7;

[0038] A support assembly is provided on the steel bar frame body 1. The support assembly includes a round sleeve 12 fixedly installed on the steel bar frame body 1. A first spring 13 is connected to the inside of the round sleeve 12. The end of the first spring 13 is connected to a telescopic rod 14 fixed to the connecting frame 16. A rope sleeve 15 adapted to the measuring rope 7 is fixedly installed at the end of the telescopic rod 14.

[0039] Specifically, during measurement, the staff rotates the activity handle 3, so that the activity handle 3 drives the steel bar frame body 1 to rotate through the round block 2, loosening the measuring rope 7 from the steel bar frame body 1, and enabling the gravity block 9 to drive the measuring rope 7 to move into the hole by its own gravity. After the measuring rope 7 reaches the bottom of the hole, the value corresponding to the marking line 8 is read. Subsequently, the length of the measuring rope 7 outside the marking line 8 is measured with a tape measure, and the two are added together. Finally, the accurate hole depth data can be obtained, thereby improving the measurement accuracy;

[0040] The staff reverses the activity handle 3 to drive the steel bar frame body 1 to reverse, so that the measuring rope 7 is wound around the steel bar frame body 1, facilitating the storage of the measuring rope 7. When the measuring rope 7 drives the gravity block 9 to contact the rope sleeve 15, the activity handle 3 is rotated to a position corresponding to the fixed handle 5, and the positioning bolt 11 is screwed into the inside of the positioning hole 10, enabling the first spring 13 to abut against the gravity block 9 through the telescopic rod 14 and the rope sleeve 15 by its own elastic force, so that the measuring rope 7 is tightened on the steel bar frame body 1, thus preventing the measuring rope 7 from being scattered.

[0041] In this embodiment, a clamping mechanism is provided on the support assembly. The clamping mechanism includes a connecting frame 16 provided on the support assembly. A fixed clamp 17 is fixedly installed at the end of the connecting frame 16. A fastening bolt 18 is rotatably installed on the fixed clamp 17. A movable clamp 19 is threadedly installed on the fastening bolt 18. The fixed clamp 17 and the movable clamp 19 jointly adapt to the measuring rope 7.

[0042] Specifically, when the gravity block 9 drives the measuring rope 7 to move to the bottom of the hole, the staff twists the fastening bolt 18 so that the fastening bolt 18 uses the thread action to drive the movable clamp 19 close to the fixed clamp 17, so that the fixed clamp 17 and the movable clamp 19 cooperate with each other to clamp and fix the measuring rope 7, and then move the measuring rope 7 out of the hole. The clamping point is measured by the marking line 8 and the tape measure to further measure the hole depth and avoid errors.

[0043] In this embodiment, an elastic mechanism is provided on the steel frame 1, and the elastic mechanism includes an axis rod 20 fixedly mounted on the steel frame 1, a torsion spring 21 is connected to the steel frame 1, and the end of the torsion spring 21 is connected to a fixed block 22 adapted to the axis rod 20, and a touch assembly is provided on the fixed block 22, and a toggle frame 27 adapted to the measuring rope 7 is fixedly mounted on the fixed block 22, and the touch assembly includes a long rod 23 fixedly mounted on the fixed block 22, and the inner wall of the end of the long rod 23 is connected to a second spring 24, and the end of the second spring 24 is connected to a telescopic block 25 adapted to the inner wall of the end of the long rod 23, and a touch block 26 is fixedly mounted on the telescopic block 25, and a plurality of clamping blocks 28 adapted to the touch block 26 are fixedly mounted on the round shell 4.

[0044] Specifically, when the staff retracts the measuring rope 7 by rotating the movable handle 3, the frame drives the long rod 23 to rotate through the shaft 20 and the fixed block 22, so that the long rod 23 drives the touch block 26 to move through the second spring 24 and the telescopic block 25, so that the touch block 26 is engaged with multiple blocks 28, so that the long rod 23 drives the toggle frame 27 through the fixed block 22 to toggle the measuring rope 7. When the touch block 26 squeezes the block 28 to a certain extent, the touch block 26 moves into the end of the long rod 23 by squeezing the second spring 24, so that the touch block 26 is separated from the block 28, so that the torsion spring 21 can use its own elastic force to drive the toggle frame 27 to rotate and reset through the fixed block 22, and to toggle the measuring rope 7 again, so that the mud and dust on the surface of the measuring rope 7 can be cleaned.

[0045] Working principle: When measuring, the worker rotates the movable handle 3, which drives the steel frame 1 to rotate through the round block 2, so that the steel frame 1 loosens the measuring rope 7, and the gravity block 9 uses its own gravity to drive the measuring rope 7 to move into the hole. When the measuring rope 7 reaches the bottom of the hole, the worker screws the fastening bolt 18, so that the fastening bolt 18 uses the thread action to drive the movable clamp 19 close to the fixed clamp 17, so that the fixed clamp 17 and the movable clamp 19 cooperate with each other to clamp the measuring rope 7. The measuring rope 7 is removed from the hole, and the value corresponding to the marked line 8 is read. Then, a tape measure is used to measure the area outside the marked line 8. The length of the measuring rope 7 is calculated by adding the two together, and finally the accurate hole depth data can be obtained. By reversing the movable handle 3, the movable handle 3 drives the steel frame 1 to reverse, so that the measuring rope 7 is wound around the steel frame 1, thereby facilitating the storage of the measuring rope 7. When the measuring rope 7 drives the gravity block 9 to contact the rope loop 15, the movable handle 3 is rotated to the position corresponding to the fixed handle 5, and the positioning bolt 11 is screwed into the inner side of the positioning hole 10, so that the first spring 13 uses its own elastic force to abut the gravity block 9 through the telescopic rod 14 and the rope loop 15, so that the measuring rope 7 is tightened on the steel frame 1;

[0046] When the movable handle 3 is rotated to store the measuring rope 7, the frame drives the long rod 23 to rotate through the shaft 20 and the fixed block 22, so that the long rod 23 drives the touch block 26 to move through the second spring 24 and the telescopic block 25, so that the touch block 26 is engaged with multiple blocks 28, so that the long rod 23 drives the toggle frame 27 through the fixed block 22 to toggle the measuring rope 7. When the touch block 26 squeezes the block 28 to a certain extent, the touch block 26 moves into the end of the long rod 23 by squeezing the second spring 24, so that the touch block 26 is separated from the block 28, so that the torsion spring 21 can use its own elastic force to drive the toggle frame 27 to rotate and reset through the fixed block 22, and the measuring rope 7 is toggled again to clean the mud and dust on the surface of the measuring rope 7.
