Description

Technical Field

[0001] This utility model belongs to the field of foundation probing technology, and particularly relates to building foundation testing, specifically a probing device with data segmentation reminder function. Background Technology

[0002] Ground penetration testing, also known as dynamic cone penetration test (DPT), involves driving a standard-sized cone probe connected to a probe rod into the soil using a weighted hammer. The mechanical properties of the soil are determined by the number of blows (N value) required to penetrate to a certain depth. For lightweight penetration tests, the hammer weight is 10 kg, and the number of blows (N10) is recorded for every 30 cm of penetration. It is primarily used for assessing foundation bearing capacity and evaluating the effectiveness of foundation treatment.

[0003] With the advancement of technology, drilling machines are gradually replacing manual tamping methods to save labor costs and improve work efficiency. The design of new drilling machines takes into account improving detection accuracy and stability. For example, the automatic rising and free falling of the hammer through a pneumatic and chain-guided hammer system transforms traditional manual operation into fully automatic operation, reducing labor intensity and improving work efficiency.

[0004] Existing fully automated penetration testing machines have achieved automation in light dynamic penetration testing, but their data recording accuracy is insufficient, and they generally lack reminders for segmented counting. Recorders often miss recording times due to noisy environments. Utility Model Content

[0005] The purpose of this invention is to improve upon existing probing machines by addressing the shortcomings of current technology, and to provide a probing device with a data segmentation reminder function. This objective is achieved through the following technical solution: A probing device with data segmentation reminder function includes a probing machine body; the probing machine body includes: a frame, a slide connected to the frame and sliding up and down, a probe rod installed at the lower part of the slide, a hammering assembly installed on the slide for hammering the probe rod, and a hammering number sensing element; the probing device also includes a movable sensing assembly installed on the slide, multiple fixed sensing assemblies arranged vertically at a certain interval on one side of the frame, and a control box; The mobile sensing component includes a first Hall magnetic proximity switch and a second magnet; each fixed sensing component includes a second Hall magnetic switch and a first magnet; when the mobile sensing component moves to the horizontal height of any fixed sensing component, the first Hall magnetic proximity switch corresponds to the position of the first magnet and is inductively connected to generate an electrical signal that is transmitted to the control box; the second Hall magnetic proximity switch corresponds to the position of the second magnet and is inductively connected to generate an electrical signal that is transmitted to the control box. The control box includes a segmented alarm module, a probe depth indicator module, a counting module, and a display screen. The first Hall magnetic proximity switch is electrically connected to the segmented alarm module and the counting module, and the second Hall magnetic proximity switch is electrically connected to the probe depth indicator module. The hammer strike count sensor is electrically connected to the counting module.

[0006] In one embodiment, the carriage includes an outer frame and a mounting bracket connected within the outer frame. The hammering assembly includes a drive motor, a transmission assembly consisting of a chain and sprockets, a hammer, and a hammer slide rail. The drive motor is fixed on the mounting bracket, and the hammer slide rail is located in the middle of the mounting bracket. The transmission assembly is connected to the drive motor to drive the chain transmission. The chain is provided with an outwardly protruding traction member to pull the hammer upward along the hammer slide rail. After the hammer is lifted to the highest point, it slides down to hammer the probe.

[0007] The outer frame of the carriage is a rectangular frame composed of two side rods, an upper connecting rod, and a lower connecting rod. Each of the two side rods is provided with a vertical sliding groove. A probe is installed in the middle of the lower connecting rod, and the axis of the probe is opposite to the center of the counterweight.

[0008] Further optimization includes a mounting frame with a horizontal crossbar, two sets of sprockets installed below and below the horizontal crossbar respectively, and a chain connected to the two sets of sprockets. The rotation of the sprockets drives the chain to move up and down. A hammer strike count sensor is installed through a hole in the horizontal crossbar. The hammer strike count sensor is an infrared diffuse reflection proximity switch. The position of the infrared diffuse reflection proximity switch corresponds to the position of the traction component on the chain. Each time the chain moves, the traction component pulls the hammer to complete one hammer strike, and the traction component passes through the infrared diffuse reflection proximity switch once and generates an electrical signal that is sent to the counting module of the control box.

[0009] Furthermore, the motion sensing component is fixed to the carriage by a first T-shaped bracket, and the Hall magnetic proximity switch and the second magnet are respectively fixed to the front and rear sides of the top plate of the first T-shaped bracket.

[0010] Furthermore, each fixed sensing component is sequentially fixed to a long strip-shaped fixing frame via a second T-shaped bracket. The long strip-shaped fixing frame includes a vertical stainless steel rail and a linear toothed groove that engages with the stainless steel rail. The stainless steel rail is fixedly connected to one side of the frame. The second Hall magnetic switch and the first magnet are respectively fixed to the front and rear sides of the top plate of the second T-shaped bracket.

[0011] The advantages and beneficial effects of this utility model are: The probing device provided by this invention can realize segmented probing data reminders and segmented hammer strike counts and displays, reducing the error rate and recording difficulty for on-site recording. This probing device features a movable sensing component on the slide and a corresponding fixed sensing component on the frame, reducing ranging errors and error aggregation. Simultaneously, it uses a Hall magnetic proximity switch, unaffected by environmental conditions, and can accurately provide distance feedback. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0015] Example 1: like Figure 1 , 2A probing device with data segmentation reminder function includes a probing machine body; the probing machine body includes: a frame 1, a slide 2 slidably connected to and sliding vertically with the frame 1, a probe 3 installed at the lower part of the slide 2, and a hammering assembly 6 and a hammering count sensor installed on the slide 2 for hammering the probe 3. The probing machine body also has a pulley assembly connected to the slide 2 for lifting the slide upwards to pull out the probe, which is a prior art feature.

[0016] In this embodiment, the slide 2 includes an outer frame and a mounting bracket connected within the outer frame. The outer frame of the slide 2 is a rectangular frame composed of two side rods, an upper connecting rod, and a lower connecting rod. Each of the two side rods has a vertically oriented sliding groove. A probe 3 is installed in the middle of the lower connecting rod, and the axis of the probe 3 is opposite to the center of the counterweight 64. The mounting bracket includes two parallel vertical rods and a horizontal crossbar 21.

[0017] like Figure 3 As shown, the hammering assembly 6 includes: a drive motor 61, a transmission assembly consisting of a chain 62 and a sprocket 63, a hammer 64, and a hammer slide rail. The drive motor 61 is fixed on the mounting frame, and the hammer slide rail is located in the middle of the mounting frame. The transmission assembly is connected to the drive motor 61 to drive the chain 62. In this embodiment, the upper and lower sets of sprockets 63 are respectively installed below and below the horizontal crossbar 21. The chain 62 is connected to the upper and lower sets of sprockets 63, and the rotation of the sprockets 63 drives the chain 62 to move up and down. The chain 62 is provided with an outwardly protruding traction member 65 to pull the hammer 64 upward along the hammer slide rail. After the hammer 64 is lifted to the highest point, it slides down and hammers the probe rod 3. The hammer moves back and forth on the slide, hammering the probe rod, thereby driving the probe rod 3 into the soil at different depths.

[0018] In this embodiment, the probing device also includes a movable sensing component 4 mounted on the slide 2, eight fixed sensing components 5 arranged vertically on one side of the frame 1 at 30cm intervals, and a control box.

[0019] The movable sensing component 4 includes an NPN type first Hall magnetic proximity switch 41 and a second magnet 42; each fixed sensing component 5 includes an NPN type second Hall magnetic switch 52 and a first magnet 51; when the movable sensing component 4 moves to the horizontal height of any fixed sensing component 5, the first Hall magnetic proximity switch 41 corresponds to the position of the first magnet 51 and is inductively connected to generate an electrical signal, and the second Hall magnetic proximity switch 52 corresponds to the position of the second magnet 42 and is inductively connected to generate an electrical signal; when the movable sensing component 4 on the slide 2 passes through 8 fixed sensing components 5 at 0, 30, 60, 90, 120, 150, 180, and 210 cm in sequence with the drilling progress, it will generate 8 electrical signals to transmit to the control box 10.

[0020] like Figure 4 , 5 As shown, the motion sensing component 4 is fixed to the slide 2 via a first T-shaped bracket 101. The first Hall magnetic proximity switch 41 and the second magnet 42 are respectively fixed to the front and rear sides of the top plate of the first T-shaped bracket 101 at the same horizontal height. The middle plate of the first T-shaped bracket 101 is fixedly connected to the slide 2 via bolts. Each fixed sensing component 5 is sequentially fixed to a long strip-shaped fixing frame 20 via a second T-shaped bracket 201. The long strip-shaped fixing frame 20 includes a vertical stainless steel rail 203 and a linear toothed groove 202 that engages with the stainless steel rail 203. The stainless steel rail 203 is fixedly connected to one side of the frame 1. The second Hall magnetic switch 52 and the first magnet 51 are respectively fixed to the front and rear sides of the top plate of the second T-shaped bracket 201 at the same horizontal height. The signal line of the second Hall magnetic switch 52 can enter the linear toothed groove 202.

[0021] like Figure 3 As shown, a hammer strike number sensor, namely an NPN type infrared diffuse reflection proximity switch 66, is installed through a hole in the horizontal bar 21. The position of the NPN type infrared diffuse reflection proximity switch 66 corresponds to the position of the traction member 65 on the chain 62. Each time the chain 62 is driven, the traction member 65 pulls the hammer 64 to complete one hammer strike, and the traction member 65 passes through the NPN infrared diffuse reflection proximity switch 66 once and generates an electrical signal that is sent to the control box 10.

[0022] The location of the control box 10 is not limited; it can be installed on or outside the rack 1. The control box is equipped with a display screen 11 to show the counting status. Figure 6 As shown, the control box includes a segmented alarm module, a probe depth indicator module, and a counting module.

[0023] The first Hall magnetic proximity switch 41 is electrically connected to the segmented alarm module and the counting module. In this embodiment, the segmented alarm module includes a time-delay relay 71, an intermediate relay 72, a buzzer alarm 73, and an alarm cancellation button, all electrically connected. The first Hall magnetic proximity switch 41 transmits an electrical signal to the intermediate relay 72 and the time-delay relay 71, driving the buzzer alarm 73 to alert the operator to distinguish the seven-segment count. The specific alarm circuit connection can use conventional circuits in the prior art. The counting module includes a counter 91 and a remote communication transmission device 92. The first Hall magnetic proximity switch 41 transmits an electrical signal to the counter 91, which can refresh and reset to zero to record the number of hammer blows in the current segment. Counters in the prior art can all achieve the above function. The segmented count can be displayed on the display screen 11.

[0024] The second Hall magnetic proximity switch 52 is electrically connected to the probe depth indication module. In this embodiment, the probe depth indication module includes electrically connected components: a multi-channel voice control board 81, a voice speaker 82, a volume switch, and a volume adjustment knob. Each voice control channel of the multi-channel voice control board 81 is connected to a corresponding second Hall magnetic proximity switch 52. The second Hall magnetic proximity switch 52 transmits an electrical signal to the multi-channel voice control board 81 (an eight-channel voice control module is used in this embodiment), driving the voice speaker 82 to sequentially play eight voice prompts indicating the specific depths of 0, 30, 60, 90, 120, 150, 180, and 210 cm. As a further optimization, the probe depth indication module may also include signal status indicator lights 83. The number of indicator lights 83 is the same as the number of second Hall magnetic proximity switches 52. Each second Hall magnetic proximity switch 52 is connected to a circuit of one indicator light 83. Different indicator lights flash to indicate different depths of 0, 30, 60, 90, 120, 150, 180, and 210 cm.

[0025] The NPN infrared diffuse reflection proximity switch 66 is electrically connected to the counting module in the control box 10. Each time the chain 62 drives, the traction member 65 pulls the hammer 64 to complete one hammer strike. The traction member 65 passes through the NPN infrared diffuse reflection proximity switch 66 once, generating an electrical signal. This signal is sent to the counting module in the control box 10 to count one hammer strike. The electrical signal is then sent to the counter module 91, which displays the real-time hammer strike count on the display screen 11. Simultaneously, the remote communication transmission device 92 attached to the counting module can upload data to a server, allowing real-time and historical data to be viewed simultaneously on a mobile app and a web browser.

[0026] The components used in this utility model are from the prior art: 1) NPN Hall effect magnetic proximity switch: The sensing element of a Hall effect proximity switch is a chip integrating a Hall voltage amplifier, while the magnetic field is provided by a magnet above the sensor body. Once an object approaches the sensing element, the sensor detects its presence and outputs an electrical signal. It features fast response and high reliability, is suitable for detecting high-speed moving objects, and because it has no mechanical contacts, it is not easily worn, has a long lifespan, and good stability.

[0027] 2) NPN type infrared diffuse reflection proximity switch: The NPN infrared diffuse reflection proximity switch works by emitting infrared light and detecting the reflected beam. When an object approaches, the emitted infrared light is reflected by the object and then captured by the sensor's receiver.

[0028] 3) Counter: The counter uses a microprocessor to implement the counting function. The microprocessor receives signals from sensors or other input devices, and the software program inside the microprocessor increments the count value according to the input signal. The count value is stored in the microprocessor's memory and can be displayed through a display screen or other output devices.

[0029] 4) Time Delay Relay: A time delay relay is a solid-state timer with multiple delay modes and control functions. When the hammer strikes across the segment boundary for a very short time, the brief electrical signal cannot provide a continuous alarm indication. Using a time delay relay can trigger a self-locking delay to disconnect after a set time, thus achieving the function of continuous alarm indication.

[0030] 5) Eight-channel voice control board: The eight-channel voice control board is a circuit board that integrates voice playback functionality. It can store and play up to eight different voice messages. The level-triggered playback terminal (PLAYL) starts playing voice when the PLAYL level changes from low to high, and continues until the PLAYL level returns to low. When the segmented electrical signal of the NPN Hall magnetic proximity switch triggers the trigger sound segment of the voice control board, the corresponding segmented voice message will be played through the speaker.

[0031] Existing commercially available technologies typically use electric probing machines, which only reduce the physical labor intensity of hammering but offer no practical help in recording probing data. During the foundation probing stage, the noisy environment makes it difficult for workers to concentrate on counting, often leading to inaccurate and distorted data. This device, however, can provide alarm prompts in seven zones, offering operational guidance in each zone, and recording and displaying the number of hammer blows, thus avoiding the mental strain of workers constantly monitoring the segments and the number of blows.

[0032] Finally, it should be noted that the above is only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to the preferred arrangement, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model.
