Description

Technical Field

[0001] The present invention relates to the technical field of driving test pile poles, and particularly to an easily disassembled and automatically reset driving test pile. Background Art

[0002] Currently, the pile poles for driving tests generally have a base fixed on the ground, and then a pile pole is inserted on it. There are also cases where a spring is installed between the pile pole and the base.

[0003] For driving test pile poles without springs, when they are hit, with a relatively small force, they will be deformed and bent by the impact, and may also shift in position. With a slightly larger force, they will break and fall. In some cases, the base of the pile pole is separated from the pile pole. To avoid deformation of the pile pole, the pile pole is made of a flexible material. When hit, the pile pole may deform and then rebound, but with such a connection method, after the pile pole is slightly hit, it cannot return to its original position. During the driving test, the position of the pile pole will change, resulting in possible loss of accuracy in the subsequent test results. Therefore, pile poles with springs at the base have replaced the original structure.

[0004] This kind of pile pole with a spring has the function of position restoration. When hit, the spring will make the pile pole return to its original position, and there is no need for personnel to straighten and adjust it anymore. However, this kind of pile pole has certain limitations. When the force of a side impact is too large, the spring of the pile pole will undergo permanent changes, resulting in the pile pole being unable to recover anymore and can only be scrapped. Moreover, because the spring of this kind of pile pole has a relatively large strength, it will be compressed when hit, and when the compressive force disappears, it will rebound with a relatively large force, which may cause injury to people or vehicles when rebounding.

[0005] This kind of spring-shaped pile pole is relatively difficult to disassemble. After installation, it can only stand in place. Currently, driving tests require the use of sensors for monitoring, that is, vibration sensors need to be installed inside the pile pole. However, the base of this kind of pile pole is fixed, and sensors can only be installed above the spring to sense vibrations. When a little more weight is added to the upper part of the pile pole, the center of gravity is relatively high. Therefore, even a slight wind can cause the pile pole to vibrate slightly, resulting in inaccurate monitoring and possible errors. Therefore, the weight of the pile pole needs to be controlled, the lighter the better, and the position of the sensor needs to be low, the lower the center of gravity, the more stable. This kind of pile pole is difficult to disassemble and assemble. When the power of the sensor is exhausted and needs to be replaced, the operation is cumbersome. Moreover, when it rains heavily, the pile pole and the internal sensor are exposed to the rain, and there is a risk of damage due to water ingress. If it is fully enclosed, it becomes even more difficult to replace the power.

[0006] Based on this, the present invention designs an easily disassembled and automatically reset driving test pile to solve the above problems. Summary of the Invention

Detailed implementation mode

[0043] Please refer to Figures 1 to 7 As shown in the figure, the present invention provides a technical solution: an easily disassembled and automatically reset driving test pile, comprising:

[0044] A limit guide sleeve 1, a docking cylinder 2, a flange base 3, a connecting column 4 and a pile rod 5;

[0045] The bottom of the flange base 3 is locked to the ground by bolts. A limit boss 31 is convexly provided at the top of the flange base 3, and a locking hole 32 is opened at the center of the top of the limit boss 31;

[0046] The upper section of the limit guide sleeve 1 is a frustum of a cone with a smaller upper part and a larger lower part, the lower section of the limit guide sleeve 1 is a cylinder, a clamping groove 11 is opened downward at the center of the top of the limit guide sleeve 1, a limit groove 12 is opened upward at the center of the bottom of the limit guide sleeve 1, and the limit groove 12 can be detachably sleeved outside the limit boss 31;

[0047] The connecting column 4 is an elastic columnar structure. The lower half of the connecting column 4 is clamped in the locking hole 32, and the upper half of the connecting column 4 is clamped in the clamping groove 11;

[0048] The upper section of the docking cylinder 2 is a frustum of a cone with a smaller upper part and a larger lower part, the lower section of the docking cylinder 2 is a cylinder, the lower section cylinder of the docking cylinder 2 can be detachably and tightly inserted into the clamping groove 11, the upper section of the docking cylinder 2 is tightly sleeved on the lower end of the pile rod 5, a placement bin 22 is opened at the bottom of the docking cylinder 2, and a monitoring device 24 is hermetically installed in the docking cylinder 2;

[0049] The vertical axes of the limit guide sleeve 1, the docking cylinder 2, the flange base 3, the connecting column 4 and the pile rod 5 coincide. It provides that it can automatically return to its original position after being slightly collided, and when being collided with a greater force, it can fall down to avoid the pile rod 5 from rebounding and hurting people. Moreover, this device is convenient to disassemble and assemble. After falling down, it can be conveniently installed and used normally, and the battery can also be conveniently replaced. And during heavy rain, it can be easily pulled out and stored to avoid being damaged by water immersion of the monitoring device. And when receiving a greater impact force, it will directly fall down for buffering to avoid permanent damage.

[0050] Among them, the docking cylinder 2 is an integral structure made of bakelite;

[0051] A circular docking groove 21 is formed at the top of the docking cylinder 2. The placement chamber 22 is a circular groove formed by the docking cylinder 2 extending upward from the center of the bottom. The docking groove 21 and the placement chamber 22 are sealed and isolated from each other.

[0052] The monitoring device 24 includes a vibration sensor, a Bluetooth data module, and a battery. A sealing cover is also provided at the bottom opening of the placement chamber 22. The placement chamber 22 and the sealing cover are tightly locked in a threaded and sealed manner. The monitoring device 24 is locked inside the placement chamber 22 sealed by the sealing cover.

[0053] The lower end of the pile rod 5 is inserted into the docking groove 21. The docking groove 21 and the pile rod 5 are in interference fit.

[0054] At least two sealing rings 23 are also annularly arranged on the outer cylindrical wall of the lower section of the docking cylinder 2. The docking cylinder 2 is hermetically inserted into the clamping groove 11 through the sealing rings 23. The docking cylinder 2 and the clamping groove 11 are in interference fit.

[0055] The vertical axes of the docking cylinder 2, the clamping groove 11, the docking groove 21, the placement chamber 22, and the limiting groove 12 coincide. The installation of the pile rod 5 and the monitoring device 24 is carried out through the docking cylinder 2, which plays a connecting role between the upper and lower parts. And the round table plays a role in guiding and positioning, limiting the axis calibration, and preventing the monitoring device 24 from getting wet, playing a role in sealed connection. The deformation displacement is at the bottom limiting guide sleeve 1. Therefore, each component has different functions, and the overall force-bearing effect is achieved after assembly.

[0056] The limiting guide sleeve 1 is an integral structure made of stainless steel. The upper section of the limiting guide sleeve 1 is a frustum structure with a smaller upper part and a larger lower part. The clamping groove 11 inside the upper frustum of the limiting guide sleeve 1 is a vertically arranged cylindrical groove. The limiting groove 12 inside the limiting guide sleeve 1 is a vertically arranged cylindrical groove.

[0057] A partition 14 is horizontally arranged inside the limiting guide sleeve 1. The partition 14 separates the clamping groove 11 and the limiting groove 12. A through hole 13 is formed at the center of the partition 14. The clamping groove 11 and the limiting groove 12 are communicated through the through hole 13.

[0058] The limiting groove 12 and the limiting boss 31 are in clearance fit. Through the structure of the limiting guide sleeve 1, the functions of connection and installation can be achieved, and the center of gravity can be reduced. It can also play a role in restricting the connecting column 4, so that the connecting column 4 can generate a restoring force during connection deformation.

[0059] The connecting column 4 is an integral frustum structure made of urethane rubber, with a truncated cone shape that is larger at the top and smaller at the bottom. A clamping ring groove 41 is provided around the conical side wall of the connecting column 4. The clamping ring groove 41 is opened on the middle section of the connecting column 4. The vertical axis of the connecting column 4 is perpendicular to the annular plane where the clamping ring groove 41 is located. A water permeable hole 42 is opened on the vertical axis of the connecting column 4, and the water permeable hole 42 vertically penetrates the connecting column 4;

[0060] The connecting column 4 and the through hole 13 are in interference fit. The top platform of the flange base 3 is embedded and clamped in the clamping ring groove 41, and the top platform of the flange base 3 and the clamping ring groove 41 are in clearance fit;

[0061] The lower end of the connecting column 4 is clamped in the locking hole 32. The connecting column 4 and the locking hole 32 are in interference fit. The locking hole 32 is a round hole, and the limiting boss 31 is a frustum. The locking hole 32 penetrates the flange base 3 in the up and down direction;

[0062] The vertical axes of the through hole 13, the limiting boss 31, the locking hole 32, the connecting column 4, and the water permeable hole 42 coincide. Limiting and guiding are carried out through the elastic material and structure of the connecting column 4, so that the device can automatically return to its original position when subjected to a small impact, and there will be no excessive reverse elastic force, only it will return to the vertical position, avoiding reverse impact and hurting people;

[0063] Annular strong magnets are provided inside the flange base 3 and inside the clamping groove 11. The limiting guide sleeve 1 and the limiting boss 31 are adsorbed by the strong magnets, which is convenient for buffering and calibrating the position through magnetic adsorption, so that the pile rod 5 can be aligned every time it is installed, ensuring that the pile rod 5 is vertical;

[0064] The pile rod 5 is a vertically arranged long carbon fiber rod. The length of the pile rod 5 is 1.8 - 1.9 meters, which reduces the weight of the pile rod 5 and increases its strength. Thus, while increasing the strength, the overall center of gravity of the device is lowered, making the center of gravity concentrated on the flange base 1 and increasing the overall stability.

[0065] In a specific embodiment of the present invention:

[0066] In an embodiment of the present invention, an easily disassembled and automatically reset driving test pile is provided. The technical problems encountered in the present invention are as follows: 1. Springs are basically provided at the bottom of current driving test piles to return to their original positions after being impacted and deflected. However, during long-term use of such driving test piles with springs, fatigue is likely to occur, resulting in permanent deformation of the springs and inability to return to their original positions, leading to failure. The elastic force of the spring stores kinetic energy after being compressed and then returns to its original position after the vehicle leaves. After long-term use like this, the locking bolts at the bottom will generate reaction forces with the ground frequently, causing the bolts on the ground to become loose and the flange locked on the ground to deform, and the monitoring pile pole will no longer be vertical, and the upright position will be inaccurate; 2. This spring-shaped mechanism has a force-bearing limit. When impacted, it will be subjected to a large pressing force and the spring will be compressed. Once the person exits the vehicle, the elastic force of the spring will suddenly release and it is very easy to bounce back in the opposite direction, injuring the vehicle and the driver, posing a safety hazard; 3. The heavier the spring, the greater the elastic force it can bear, but the heavier the device, the more unstable the center of gravity of the pile pole 5 will be, and it is easy to skew, resulting in inaccurate monitoring. The elastic connection has instability and is easily affected by ground vibrations caused by vehicle driving and the influence of strong winds, resulting in slight vibrations, thus leading to misjudgment, and the monitoring state is also affected by the spring.

[0067] The achieved technical effects are as follows: 1. The present invention does not use a spring, reducing the weight and height of the spring, thereby reducing the overall weight of the pile pole 5 of the present device and also reducing the height of the relatively heavy monitoring device, making the overall center of gravity height of the pile pole 5 also decrease, making the present device more stable, avoiding interference from its own vibrations and swaying caused by wind, and improving the monitoring accuracy;

[0068] 2. The present device uses stable limiting by magnetic adsorption and sleeve hard connection, making the present device accurately return to its original position after a slight impact. It will not be fixed at the deflected angle position, but will return to the coaxial vertical state of its original position, thus effectively returning to its original position, and can also be conveniently installed and calibrated in the vertical state during disassembly and assembly. As long as it is magnetically adsorbed, the position can be ensured to be accurate;

[0069] 3. The present device is easy to disassemble and assemble, and can conveniently remove and take away the monitoring device 24 to avoid damage to the monitoring device 24 caused by flooding. When there is relatively small rain, the monitoring device 24 of the present device is installed in the placement bin 22 and is sealed, with only an opening at the bottom, which can effectively seal and prevent rainwater from entering. As long as the docking cylinder 2 of the present device is not immersed in water, the monitoring device 24 can be protected from water ingress.

[0070] The technical solution in the embodiment of the present invention to solve the above problems has the following general idea:

[0071] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the specification drawings and specific implementation manners.

[0072] When the present invention is manufactured, first, a limit guide sleeve 1, a docking cylinder 2, a flange base 3, a connecting column 4 and a pile rod 5 are manufactured;

[0073] The flange base 3 is an integral structure made of stainless steel to avoid rust caused by long-term outdoor use. The flange base 3 is positioned at a preset position, and then the flange base 3 is locked to the ground with bolts to ensure that the flange base 3 is fixed. The flange base 3 has a low height to improve stability;

[0074] There is a protruding limit boss 31 on the top of the flange base 3. The limit boss 31 is a cylinder, and a locking hole 32 is opened at the top of the limit boss 31. The locking hole 32 penetrates the flange base 3 from top to bottom, so that the upper part of the flange base 3 communicates with the ground through the locking hole 32, which is convenient for drainage;

[0075] Then, a cylindrical structure is made of polyurethane rubber as the connecting column 4. A water permeable hole 42 is opened on the vertical axis of the connecting column 4. A clamping ring groove 41 is opened on the annular outer side wall of the connecting column 4. The plane where the clamping ring groove 41 is located is perpendicular to the vertical axis of the connecting column 4. The plane where the clamping ring groove 41 is located is the middle section of the connecting column 4. The upper half of the connecting column 4 is above the clamping ring groove 41, and the lower half of the connecting column 4 is below the clamping ring groove 41; Polyurethane rubber has elasticity and can guide and return the devices connected to both ends of the connecting column 4, but it does not have a particularly strong reaction elastic force, effectively avoiding the problem of excessive rebound amplitude of the pile rod 5;

[0076] The connecting column 4 is tightly inserted into the locking hole 32 on the top of the flange base 3; The connecting column 4 and the locking hole 32 are in interference fit; The top platform of the flange base 3 is clamped in the clamping ring groove 41, so as to clamp and limit the position of the connecting column 4 and avoid the connecting column 4 from tilting,

[0077] The limit guide sleeve 1 is composed of upper and lower parts. The upper and lower parts of the limit guide sleeve 1 are an integral structure and are also made of stainless steel. The upper section of the limit guide sleeve 1 is a frustum structure, and the lower section is a cylinder. A partition 14 is arranged inside the limit guide sleeve 1. The partition 14 is horizontally arranged. The axis of the limit guide sleeve 1 is vertically arranged. A clamping groove 11 is opened downward from the top of the limit guide sleeve 1, and a limit groove 12 is opened upward from the bottom of the limit guide sleeve 1. The clamping groove 11 and the limit groove 12 are separated by the partition 14, and a through hole 13 is opened on the partition 14. The clamping groove 11 and the limit groove 12 are communicated through the through hole 13. The inner diameter of the limit groove 12 is the same as the inner diameter of the limit boss 31, which is an interference fit. A ring-shaped neodymium magnet is adsorbed below the top platform of the limit boss 31, and a ring-shaped neodymium magnet is also fixedly arranged at the bottom of the clamping groove 11 above the partition 14. In this way, the partition 14 is adsorbed to the top of the limit boss 31 by strong magnetic force, and the neodymium magnets adsorb each other across the limit boss 31 and the partition 14. Such magnetic adsorption not only plays a role in fitting, guiding and calibration, but also plays a role in mutual adsorption and locking;

[0078] The docking cylinder 2 also needs to be manufactured. The docking cylinder 2 is an integral structure made of bakelite. The docking cylinder 2 is also composed of upper and lower sections and is also an integral structure. The upper section of the docking cylinder 2 is a circular frustum, and the lower section of the docking cylinder 2 is a cylinder. A docking groove 21 is opened downward at the top of the docking cylinder 2. The docking groove 21 has an interference fit with the pile rod 5. The docking cylinder 2 has a certain elasticity to ensure that the pile rod 5 is inserted tightly. And an installation bin 22 is opened upward at the bottom of the docking cylinder 2. The installation bin 22 is filled with a monitoring device 24. The monitoring device 24 has been widely used in driving test piles to detect whether the device is impacted through vibration. The monitoring device 24 is a conventional vibration sensor, a Bluetooth data module and a battery, which can be connected and controlled through a single-chip microcomputer. The vibration is monitored by the vibration sensor, and then the signal of whether there is vibration is transmitted to the receiving end through the Bluetooth data module to know whether the pile rod 5 is vibrated;

[0079] The pile rod 5 is a carbon fiber straight rod with a length of 1.9 meters, which is the standard height of the driving test pile. The overall length of the driving test pile is lower than this height, but the longer the overall length of the driving test pile, the higher the center of gravity and the easier it is to fall. The carbon fiber pile rod 4 is light in weight and high in strength, and is not easy to break and deform even if it is impacted or run over by a wheel;

[0080] A sealing cover also needs to be installed at the bottom of the installation bin 22 at the bottom of the docking cylinder 2 to seal the monitoring device 24. The sealing cover and the installation bin 22 are installed and sealed with threads to achieve a certain sealing effect;

[0081] A sealing ring 23 is provided on the outer wall of the lower section of the docking cylinder 2 in a circumferential manner. The docking cylinder 2 is inserted tightly into the clamping groove 11 and is sealed through the sealing ring 23 to ensure that rainwater does not enter the inner part of the limit guide sleeve 1 from the gap between the docking cylinder 2 and the clamping groove 11. The docking cylinder 2 and the clamping groove 11 have an interference fit.

[0082] The lower section of the connecting column 4 is clamped inside the limit boss 31 below the locking hole 32, and the upper section of the connecting column 4 passes through the limit groove 12 and is clamped in the clamping groove 11, so as to connect and clamp the limit guide sleeve 1 and the flange base 3 through the connecting column 4.

[0083] When the present invention is in use, after the device is assembled, the pile rod 5 is tightly inserted into the docking groove 21 of the docking cylinder 2. The docking cylinder 2 is inserted into the clamping groove 11 of the limit guide sleeve 1. The limit groove 12 of the limit guide sleeve 1 is sleeved outside the limit boss 31. And a connecting column 4 with relatively small elastic flexibility is also connected between the limit guide sleeve 1 and the flange base 3. And a clamping ring groove 41 is opened on the connecting column 4, which is easy to deform along the clamping ring groove 41;

[0084] When the device is hit, the pile rod 5 is stressed, driving the docking tube 2 and the limiting guide sleeve 1 to be stressed together, because they are all interference fit and tightly clamped to form an overall force, and the limiting guide sleeve 1 and the limiting boss 31 are clearance fit, and are adsorbed by magnetic force, and are guided and connected by the connecting column 4, so that the pile rod 5 is deformed along the connecting column 4, and the impacted side of the top of the limiting boss 31 and the bottom of the limiting groove 12 are tilted, and the pile rod 5 buffers and avoids the impact, because the docking tube 2 is displaced and tilted together, the monitoring device 24 senses the vibration and sends a signal, and when the vehicle leaves and exits, it returns to its original position under the toughness of the connecting column 4, because the connecting column 4 is only tough, but does not have the reverse elastic force of the spring, and will not cause the pile rod 5 to swing in the opposite direction to injure people, and the strong magnet can make the limiting guide sleeve 1 and the limiting boss 31 magnetically adsorbed and aligned, and the strong magnet can buffer the action and reaction forces in any direction, effectively and continuously reduce the impact force, and does not have the effect of energy storage.

[0085] When the impact force is too great, the connecting column 4 is overstressed, causing the connecting column 4 to disengage from the through hole 13, so that the pile rod 4 falls down when subjected to a large impact and no longer recovers to an upright state. When the impact force is too great, the magnetic force does not store energy, and it will disengage as long as it exceeds the adsorption force, thereby achieving a buffering effect without storing energy to rebound, effectively preventing the pile rod 5 from rebounding and injuring people, and also effectively preventing the device from being damaged by a large impact force. It is just that the connecting column 4 is disengaged, and you only need to pick it up and plug it in again, which is simple and convenient to operate.

[0086] When it rains, because the interior of the placement bin 22 is sealed, even if water enters, it will flow downward along the water-permeable holes 42, the through holes 13 and the locking holes 32, and directly flow down to the ground. When the rain is heavy, the pile rod 5 can be directly pulled out and the docking tube 2 can be stored to prevent the monitoring device 24 from getting wet and damaged. All detachable parts can also be removed and stored to avoid loss.

[0087] Because the device is easy to disassemble and assemble, and the battery is more convenient to replace, the bottom of the conventional spring driving test pile is a spring, which not only may accidentally trigger the drainage, but the general monitoring device 24 is also installed in the pile rod 5, which is easily damaged by impact, and the center of gravity is generally high, which is easily disturbed by the movement of vehicles and vibrates; the device does not have these disadvantages.

[0088] Although the specific implementation modes of the present invention are described above, those skilled in the art should understand that the specific implementation modes described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
