Description

Technical Field

[0001] This utility model relates to the field of pile foundation driving technology, and in particular to an alarm device for the driving depth of building pile foundations. Background Technology

[0002] In the construction of building pile foundations, the pile driving process is a crucial step in driving precast piles or cast-in-place piles to the designed depth. The accuracy of the pile driving depth directly determines the bearing capacity of the pile foundation, and thus affects the overall structural stability and safety of the building. Therefore, it is necessary to strictly monitor and control the pile driving depth.

[0003] Currently, the industry relies heavily on manual methods to monitor the depth of pile driving in building foundations. Workers typically use tools such as tape measures and measuring ropes to manually measure the distance between the top of the pile and the ground, or rely on construction experience to determine whether the pile driving has reached the preset depth. This method is greatly affected by the precision of manual operation, interference from the construction environment (such as dust and noise), and the subjectivity of experience. Not only is the monitoring efficiency low, but it is also difficult to grasp the pile driving depth in real time and accurately, which makes it impossible to remind workers to stop driving the pile in time. Therefore, the accuracy of the pile driving depth in building foundations cannot be effectively guaranteed. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides an alarm device for the pile driving depth of building pile foundations.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a building pile foundation driving depth alarm device, comprising a monitoring-warning mechanism installed on the building pile foundation driver, the monitoring-warning mechanism including a connecting component and a monitoring-warning component, the connecting component being used to connect the monitoring-warning component to the driver, the connecting component including at least a horizontal plate, the monitoring-warning component including a distance sensor, a controller, a battery and a buzzer electrically connected to each other; the distance sensor monitors the distance between itself and the ground in real time and feeds it back to the controller, the controller calculates the driving depth of the building pile foundation into the ground, and when the driving depth reaches a preset value, controls the buzzer to sound an alarm to remind the staff to stop driving the pile immediately.

[0006] By adopting the above technical solution, the distance measuring sensor (such as SICK DT50, Dimetix D series laser distance measuring sensor or TI AWR1642 millimeter-wave radar sensor) can monitor the distance (d1) between itself and the ground in real time. The monitoring result is transmitted to the controller in the form of an electrical signal. When calculating the driving depth of the building pile foundation, since the distance between the distance measuring sensor and the lower end of the pile driver is a fixed value d0, |d1-d0| (absolute value) is the distance between the upper end of the building pile foundation and the ground. The controller compares this value with a preset value (after the building pile foundation is driven into the ground, there should be a unified standard or specification for the distance between its upper end and the ground. This value is a preset value, which is usually a range). When |d1-d0| reaches the preset value, the controller immediately controls the buzzer to sound an alarm to remind the staff to stop driving the pile immediately, thus ensuring the accuracy of the driving depth of the building pile foundation.

[0007] Furthermore, the monitoring-alert component also includes an alarm light, which is electrically connected to both the battery and the controller.

[0008] By adopting the above technical solution, when |d1-d0| reaches the preset value, the controller promptly controls the alarm light to sound an alarm. After seeing the flashing light, the staff can immediately stop driving the pile, which further improves the accuracy of the pile driving depth.

[0009] Furthermore, the connecting assembly also includes an arc-shaped connecting strip and a limiting unit. An arc-shaped connecting groove for engaging the arc-shaped connecting strip is provided on the side wall of the pile driver near its upper end. An arc-shaped connecting port, parallel to the extending direction of the arc-shaped connecting groove, is provided at the top of the arc-shaped connecting strip. One end of the arc-shaped connecting port, away from the middle of the arc-shaped connecting strip, is flush with the end of the arc-shaped connecting strip. Two arc-shaped connecting ports are provided and symmetrically arranged on both sides of the arc-shaped connecting strip. Two sets of limiting units are provided and connected to two sets of arc-shaped connecting ports respectively. Each limiting unit includes an arc-shaped locking strip, a slider, and a spring. The arc-shaped locking strip and... The arc-shaped connecting port is fitted with a slider fixed to the bottom of the arc-shaped locking strip. The bottom of the arc-shaped connecting port is provided with an arc-shaped groove that slides with the slider. The two ends of the spring are fixed to the side wall of the slider and the end side wall of the arc-shaped groove, respectively. The side wall of the pile driver is provided with an arc-shaped limiting groove that communicates with the arc-shaped connecting groove. The arc-shaped locking strip slides with the arc-shaped limiting groove. There are two arc-shaped limiting grooves, which are symmetrically arranged. The distance between the two arc-shaped limiting grooves decreases from the center of the pile driver to the side away from the arc-shaped connecting groove. A connecting plate is fixed to the side of the arc-shaped connecting strip away from the pile driver. One end of the horizontal plate is detachably connected to the connecting plate.

[0010] By adopting the above technical solution, when installing the horizontal board with monitoring and warning components, the worker only needs to push the two arc-shaped retaining strips along the arc-shaped limiting grooves, so that the slider at the bottom of the arc-shaped retaining strip compresses the spring until the arc-shaped retaining strip slides completely into the arc-shaped connecting port. At this time, the worker can easily install the arc-shaped connecting strip into the arc-shaped connecting groove. After releasing the arc-shaped retaining strips, the arc-shaped retaining strips return to their original position under the action of the spring and the slider. The two arc-shaped retaining strips cooperate and play a good cooperation role in the arc-shaped connecting strip, ensuring the stability of the arc-shaped connecting strip during use, and completing the installation of the horizontal board with monitoring and warning components.

[0011] Furthermore, a guide strip is integrally formed at the end of the arc-shaped clip away from the arc-shaped connecting groove, and the end of the guide strip away from the arc-shaped clip is bent toward the side away from the pile driver.

[0012] By adopting the above technical solution, when installing the arc-shaped connecting strip, the staff only needs to push the arc-shaped connecting strip so that after the two guide strips enter the arc-shaped connecting groove and engage, they automatically push the arc-shaped locking strip along the arc-shaped limiting groove, eliminating the tedious operation of manually pushing the arc-shaped locking strip and improving the installation efficiency of the arc-shaped connecting strip.

[0013] Furthermore, a connecting block is fixed to the side of the arc-shaped connecting strip away from the pile driver, and a lifting hole is provided on the connecting block.

[0014] By adopting the above technical solution, the portability of the connection components has been improved.

[0015] Furthermore, the pile driver is equipped with a reinforcing component, which includes a collar, a first connecting rod, and a second connecting rod. The collar is fitted onto the pile driver. The first connecting rod is fixedly connected to both the collar and the cross plate. The second connecting rod is fixedly connected to both the first connecting rod and the cross plate. Both the first and second connecting rods are inclined. The second connecting rod is located on the side of the first connecting rod away from the pile driver, and the angle between the second connecting rod and the cross plate is smaller than the angle between the first connecting rod and the cross plate.

[0016] By adopting the above technical solution, the collar, the first link, and the second link work together to ensure the stability of the horizontal plate and the monitoring-warning component during use, and to ensure the accuracy of the monitoring results.

[0017] In summary, this utility model has the following beneficial effects: In this application, the ranging sensor (such as SICK DT50, Dimetix D series laser ranging sensor or TIAWR1642 millimeter-wave radar sensor) can monitor the distance (d1) between itself and the ground in real time. The monitoring result is transmitted to the controller in the form of an electrical signal. When calculating the driving depth of the building pile foundation, since the distance between the ranging sensor and the lower end of the pile driver is a fixed value d0, |d1-d0| (absolute value) is the distance between the upper end of the building pile foundation and the ground. The controller compares this value with a preset value (after the building pile foundation is driven into the ground, there should be a unified standard or specification for the distance between its upper end and the ground, and this value is a preset value, which is usually a range). When |d1-d0| reaches the preset value, the controller immediately controls the buzzer to sound an alarm to remind the staff to stop driving the pile immediately, thus ensuring the accuracy of the driving depth of the building pile foundation.

[0020] The technical solutions in 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. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0021] Example 1 like Figure 1-6 As shown in the illustration, this application discloses a pile driving depth alarm device for building pile foundations, including a monitoring-alarm mechanism 2 installed on a pile driver 1. The monitoring-alarm mechanism 2 includes a connecting component 21 and a monitoring-alarm component 22. The connecting component 21 is used to connect the monitoring-alarm component 22 to the pile driver 1. The connecting component 21 includes at least a horizontal plate 211. The monitoring-alarm component 22 includes a distance sensor 221, a controller 222, a battery 223, and a buzzer 224, which are electrically connected to each other. The distance sensor 221 monitors the distance between itself and the ground in real time and feeds it back to the controller 222. The controller 222 calculates the depth of the building pile driven into the ground. When the driving depth reaches a preset value, it controls the buzzer 224 to sound an alarm to remind the staff to stop driving the pile immediately. The structure of the pile driver 1 and the pile driving equipment controlling the operation of the pile driver 1 are both prior art and need not be described in detail.

[0022] The ranging sensor 221 (such as SICK DT50, Dimetix D series laser ranging sensor 221, or TIAWR1642 millimeter-wave radar sensor) can monitor the distance (d1) between itself and the ground in real time. The monitoring result is transmitted to the controller 222 in the form of an electrical signal. When calculating the driving depth of the building pile foundation, since the distance between the ranging sensor 221 and the lower end of the pile driver 1 is a fixed value d0, |d1-d0| (absolute value) is the distance between the upper end of the building pile foundation and the ground. The controller 222 compares this value with a preset value (after the building pile foundation is driven into the ground, there should be a unified standard or specification for the distance between its upper end and the ground. This value is a preset value, which is usually a range). When |d1-d0| reaches the preset value, the controller 222 immediately controls the buzzer 224 to sound an alarm to remind the staff to stop driving the pile immediately, thus ensuring the accuracy of the driving depth of the building pile foundation.

[0023] It's worth noting that the SICK DT50's laser rangefinder 221 is a mature, existing technology. The SICK DT50-N2123's laser rangefinder 221 calculates distance by emitting a laser beam and measuring the time difference of the reflected light, achieving millimeter-level accuracy. It boasts strong vibration resistance and a high protection rating (IP65 / IP67), allowing stable operation in dusty and humid environments. Dimetix D-series lasers (such as the DPE and DEN models) achieve 3mm accuracy in piling operations and support a 50-meter measurement range, adapting to the vibration environment of piling machines. The TI AWR1642 millimeter-wave radar sensor utilizes the reflection characteristics of high-frequency electromagnetic waves (such as 60GHz) for distance measurement, exhibiting strong anti-interference capabilities. Its ability to penetrate dust and water mist is superior to lasers, making it suitable for complex weather conditions.

[0024] The monitoring-alert component 22 also includes an alarm light 225, which is electrically connected to both the battery 223 and the controller 222. When |d1-d0| reaches a preset value, the controller 222 promptly activates the alarm light 225 to sound an alarm. Upon seeing the flashing light, staff can immediately stop driving the pile, further improving the accuracy of the driving depth.

[0025] The connecting assembly 21 also includes an arc-shaped connecting strip 212 and a limiting unit 213. An arc-shaped connecting groove 11 for engaging the arc-shaped connecting strip 212 is provided on the side wall of the pile driver 1 near its upper end. An arc-shaped connecting port 2121 parallel to the extending direction of the arc-shaped connecting groove 11 is provided at the top of the arc-shaped connecting strip 212. One end of the arc-shaped connecting port 2121 away from the middle of the arc-shaped connecting strip 212 is flush with the end of the arc-shaped connecting strip 212. Two arc-shaped connecting ports 2121 are provided and symmetrically arranged on both sides of the arc-shaped connecting strip 212. Two sets of limiting units 213 are provided and connected to two sets of arc-shaped connecting ports 2121 respectively. Each set of limiting units 213 includes an arc-shaped locking strip 2131, a slider 2132, and a spring 2133. The arc-shaped locking strip 2131 and the arc-shaped connecting port 2121 are connected to the arc-shaped connecting port 2121. The arc-shaped connecting port 2121 is fitted with a slider 2132 fixed to the bottom of the arc-shaped locking strip 2131. The bottom of the arc-shaped connecting port 2121 is provided with an arc-shaped sliding groove 2122 that slides with the slider 2132. The two ends of the spring 2133 are respectively fixed to the side wall of the slider 2132 and the end side wall of the arc-shaped sliding groove 2122. The side wall of the pile driver 1 is provided with an arc-shaped limiting groove 12 that communicates with the arc-shaped connecting groove 11. The arc-shaped locking strip 2131 slides with the arc-shaped limiting groove 12. There are two arc-shaped limiting grooves 12, which are symmetrically arranged. The distance between the two arc-shaped limiting grooves 12 decreases from the center of the pile driver 1 towards the side away from the arc-shaped connecting groove 11. A connecting plate 3 is fixed to the side of the arc-shaped connecting strip 212 away from the pile driver 1. One end of the horizontal plate 211 is detachably connected to the connecting plate 3.

[0026] When installing the horizontal plate 211 with the monitoring-warning component 22, the operator only needs to push the two arc-shaped retaining strips 2131 along the arc-shaped limiting groove 12, so that the slider 2132 at the bottom of the arc-shaped retaining strip 2131 compresses the spring 2133 until the arc-shaped retaining strip 2131 slides completely into the arc-shaped connecting port 2121. At this time, the operator can easily install the arc-shaped connecting strip 212 into the arc-shaped connecting groove 11. After releasing the arc-shaped retaining strip 2131, the arc-shaped retaining strip 2131 returns to its original position under the action of the spring 2133 and the slider 2132. The two arc-shaped retaining strips 2131 cooperate and play a good cooperation role with the arc-shaped connecting strip 212, ensuring the stability of the arc-shaped connecting strip 212 during use, and completing the installation of the horizontal plate 211 with the monitoring-warning component 22.

[0027] The end of the arc-shaped retaining strip 2131 away from the arc-shaped connecting groove 11 is integrally formed with a guide strip 21311, and the end of the guide strip 21311 away from the arc-shaped retaining strip 2131 is bent toward the side away from the pile driver 1.

[0028] When installing the arc-shaped connecting strip 212, the operator only needs to push the arc-shaped connecting strip 212 so that after the two guide strips 21311 enter the arc-shaped connecting groove 11 and engage, they automatically push the arc-shaped locking strip 2131 along the arc-shaped limiting groove 12, eliminating the tedious operation of manually pushing the arc-shaped locking strip 2131 and improving the installation efficiency of the arc-shaped connecting strip 212.

[0029] To facilitate the carrying of the connecting component 21 by the staff, a connecting block 4 is fixed on the side of the arc-shaped connecting strip 212 away from the pile driver 1, and a lifting hole 41 is provided on the connecting block 4.

[0030] The pile driver 1 is equipped with a reinforcing component 5, which includes a collar 51, a first connecting rod 52, and a second connecting rod 53. The collar 51 is fitted onto the pile driver 1. The first connecting rod 52 is fixedly connected to both the collar 51 and the horizontal plate 211. The second connecting rod 53 is also fixedly connected to both the first connecting rod 52 and the horizontal plate 211. Both the first connecting rod 52 and the second connecting rod 53 are inclined, with the second connecting rod 53 located on the side of the first connecting rod 52 furthest from the pile driver 1. The angle between the second connecting rod 53 and the horizontal plate 211 is smaller than the angle between the first connecting rod 52 and the horizontal plate 211. The collar 51, the first connecting rod 52, and the second connecting rod 53 work together to ensure the stability of the horizontal plate 211 and the monitoring-warning component 22 during use, thus ensuring the accuracy of the monitoring results.

[0031] It is worth noting that in other embodiments, in order to further ensure the stability of the horizontal plate 211 and the monitoring-alarm component 22 during use, the width of the horizontal plate 211 can be widened and the number of connecting rods for reinforcement in the reinforcement component 5 can be increased, so that the stability of the horizontal plate 211 can be fully guaranteed.

[0032] Example 2 like Figure 7-10As shown, the key difference between this embodiment and Embodiment 1 lies in the following technical features: the monitoring-alarm component 22 does not include a ranging sensor 221; the controller 222, battery 223, buzzer 224, and alarm light 225 are directly fixed to the bottom of the connecting plate 3; and a fixing plate 6 is fixed on the pile driving equipment. A laser sensor 7, which is communicatively connected to the controller 222, is fixed on the fixing plate 6. The height of the laser sensor 7 is set according to the standard height of the pile foundation. The laser sensor 7 can be a ZYT-0100 laser ranging sensor, which is suitable for complex environments such as high temperature and dust. When this device is applied to rough roads, since the distance between the laser sensor 7 and the ground is a fixed value, the laser sensor 7 can emit laser light and receive it itself. As the pile driver 1 drives the pile, both the pile foundation and the pile driver 1 gradually sink. The controller 222, battery 223, buzzer 224 and alarm light 225 descend synchronously with the pile driver 1. When the buzzer 224 descends to the height corresponding to the laser sensor 7, the laser light emitted by the laser sensor 7 hits the buzzer 224. The reflected laser light is received by the receiver of the laser sensor 7. The controller 222 responds immediately and knows that the pile foundation has reached the driving depth. At this time, the controller 222 immediately controls the buzzer 224 and alarm light 225 to work to warn the staff to stop driving the pile immediately.

[0033] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
