Description

Technical Field

[0001] The invention belongs to the technical field of geological exploration, and in particular relates to a new type of fully automatic geological drilling machine. Background Art

[0002] Before construction, the soil conditions of the foundation should be explored to understand the soil conditions. The commonly used method is to drill the soil layer. The method is to manually swing an 8-10 pound hammer, lift it to a height of 70-80 cm, and then let it fall freely, and drive the steel drill into the soil layer little by little. Each 30-50 cm section is a section, and there are five sections in total, with a depth of 1.5-2.5 m. The number of hammers is recorded once for each section. If the number of hammers in each section is the same, it means that the soil layer is uniform. If the number of hammers in one section is less, it means that there are loose or hollow underground structures in the soil layer of that section. The disadvantage of this drilling method is that the consistency of the tamping force is poor. During the drilling process, the drilling depth and the number of hammers need to be recorded manually. The workload of data recording is large, which is easy to cause misreporting or false reporting of the number of hammers, affecting the quality of the building.

[0003] Later, some manufacturers developed fully automatic or semi-automatic drilling machines. When these traditional drilling machines are performing drilling operations, the drilling probe will produce a reaction force on the drilling probe, causing the drilling probe to gradually deviate from its original position, affecting the detection accuracy of the drilling probe. In addition, when the drilling probe is performing drilling operations, the mud and sand adhere to the outside of the drilling probe because it continuously penetrates into the soil, increasing the friction of the drilling probe on the ground, affecting the accuracy of the drilling probe, and cleaning the soil outside the drilling probe is time-consuming and laborious. To solve the above problems, the present application proposes a new fully automatic geological drilling machine. Summary of the invention

The bottom of the support rod is mechanically connected to the support plate, and the first motor installed on the support plate drives the roller brush to rotate, thereby realizing the cleaning and sweeping function of the soil at the bottom of the drill rod.

[0007] Furthermore, the roller brush includes a chuck, a hard rubber rod and a rubber ball. The chuck of the roller brush is mechanically connected to the main shaft of the first motor. A plurality of hard rubber rods are connected around the chuck. A rubber ball is arranged at the end of the hard rubber rod. The hard rubber rod and the rubber ball are injection molded. The first motor rotates to drive the roller brush to rotate, and the roller brush drives the hard rubber rod and the rubber ball on the rod to rotate. The soil at the bottom of the drill rod is continuously struck by the plurality of hard rubber rods and the rubber balls on the rod, so that the soil or other impurities are separated from the drill rod.

[0008] Furthermore, the vertical lifting mechanism includes guide rails, buffer ropes, sleeves, damping rollers, cylinders, piston rods, walking arm plates, fixed brackets and guide sleeves.

The walking arm plate is the main body of the vertical lifting mechanism, and the damping rollers are fixed on the upper and lower parts of the frame. The damping rollers are rollingly connected to the frame and are symmetrically arranged on the frame. Two buffer ropes pass through the damping rollers respectively and are embedded in the U-shaped grooves of the damping rollers. The U-shaped grooves of the damping rollers are used to limit the buffer ropes to prevent the buffer ropes from detaching from the damping rollers. The buffer ropes bypass the damping rollers on the frame, and a certain part of the buffer ropes is mechanically connected to the walking arm plate. The overall movement of the walking arm plate along the guide rail and the rotation of the damping rollers is realized, and the movement of the walking arm plate rotating around the frame is realized. The cylinder is fixed at the bottom of the frame. When the cylinder is inhaled, the piston rod is pushed outward, and when the cylinder is exhausted, the piston rod is pulled inward. Because the piston rod is mechanically connected to the walking arm plate, the piston rod pushes the walking arm plate to move upward along the guide rail when the cylinder is inflated, thereby realizing the lifting function of the vertical lifting mechanism.

[0009] Furthermore, the heavy hammer device includes a second motor, a motor bracket, a wire rope, a pulley, a slider, a rocker arm, a slide groove and a hammer body. The second motor is mechanically connected to the frame through the motor bracket, the second motor is mechanically connected to the rocker arm, the slide groove is slidably connected to the slider, a limiting groove is set on the edge of the slide groove, the limiting groove is circular as a whole, and the size of the limiting groove is larger than the width of the slide groove, the slider is mechanically connected to the hammer body through the wire rope, the wire rope passes through the pulley and is in contact with the pulley, and the pulley is rotationally connected to the frame. The second motor is the power source of the heavy hammer device, and the hammer is used to strike the drill rod. The hammer action of the hammer is mainly achieved by reciprocating motion in the vertical direction.

The middle position of the wire rope is mechanically connected to the pulley, and the rocker arm, slide groove, slider, wire rope, hammer and limit groove are used in coordination. The second motor drives the rocker arm to rotate. At this time, the slider is in the limit grooves on both sides of the slide groove. During the rotation of the rocker arm, the slider and the wire rope move with the rocker arm. When the direction of the rocker arm slide groove is consistent with the direction of the wire rope, the limiting constraint effect of the limited groove is reduced and the combined effect of the wire rope tension, the slider gradually disengages from the limit groove and moves in the common direction of the slide groove and the wire rope, and finally enters another limit groove set opposite the rocker arm slide groove, completing the first hammer hammering action. As the motor drives the rocker arm to rotate further, it reciprocates to achieve continuous hammering action.

[0010] Furthermore, the data acquisition device includes a single-chip microcomputer, a photoelectric switch and an ultrasonic distance sensor, the photoelectric switch and the ultrasonic distance sensor are electrically connected to the single-chip microcomputer respectively, the single-chip microcomputer is fixed on the frame, the photoelectric switch is mechanically connected to the vertical lifting mechanism, and the ultrasonic distance sensor is mechanically connected to the frame.

The second motor drives the rotation of the rocker arm to realize continuous hammering action. At the same time, the first motor drives the roller brush to rotate, and the roller brush drives the hard rubber rod and rubber ball to rotate. The rubber rod and rubber ball continuously hit the soil on the drill rod. During this process, the photoelectric switch monitors the number of times the hammer body hammers the drill rod and uploads the data signal to the single-chip microcomputer. When the hammering action is completed, the ultrasonic distance sensor obtains the descending distance of the vertical lifting mechanism through monitoring and uploads the measurement data signal to the single-chip microcomputer.

[0020] like Figure 1-Figure 4 As shown, a geological drilling machine for construction, the overall frame 23 is welded and formed by stainless steel profiles, has inherent anti-corrosion performance, and does not require additional anti-corrosion treatment.

[0021] The above-mentioned frame 23 is equipped with a drill rod 13, a weight device A4, a data acquisition device A1, a vertical lifting mechanism A2 and a cleaning mechanism A3. That is to say, the weight device A4, the data acquisition device A1, the vertical lifting mechanism A2 and the cleaning mechanism A3 are respectively installed on the frame 23 by different installation methods, wherein the drill rod 13 as the core component of geological drilling is vertically arranged, and a positioning pin 19 is arranged at the top of the drill rod 13 for vertical hoisting and installation of the drill rod. The cleaning mechanism A3 is arranged at the bottom of the drill rod, and the cleaning structure A3 cleans the drill head of the drill rod. An movable vertical lifting mechanism A2 is arranged above the top of the frame, and the weight device A4 is mechanically connected to the vertical lifting mechanism A2 through a pulley 22, and the above-mentioned drill rod 13 is struck by the weight device A4, and the striking direction is vertically downward. Among them, the frame 23 is used to support and install the weight device A4, the data acquisition device A1, the vertical lifting mechanism A2 and the cleaning mechanism A3. The drill rod 13 is the main implementation mechanism and is mainly used for exploring the foundation. It is installed in an upper suspension manner and is limited by the positioning pin 19. The hammer body 6 in the weight device A4 is used to hammer the drill rod 13. The data acquisition device A1 measures the depth of the drill rod into the foundation and the number of hammer body impacts through multiple sensors. The vertical lifting mechanism A2 is used to connect the drill rod 13, the weight device A4 and the data acquisition device A1, and provide vertical guide data for the drill rod 13. The cleaning mechanism A3 is used to clean and clean the drill rod 13.

[0022] like Figure 1-Figure 4 As shown, the various components of the drill probe are described in detail below in conjunction with the drawings in the specification.

[0023] The frame 23, as the skeleton of the entire equipment, is welded and formed by stainless steel profiles. The frame 23 is vertically arranged as a whole, and a top beam is arranged on the top of the frame, a bottom beam is arranged on the bottom, and a mounting platform is welded outward on the bottom beam to form a mounting platform, which is used to install the heavy hammer device A4, and a mounting platform extending downward is installed on the bottom beam, which is used to install the cleaning structure A3.

[0024] First, the cleaning mechanism A3 is introduced. The cleaning mechanism A3 includes a table 9, a rubber sleeve 26, a support rod 27, a semicircular scraper 10, a support plate 31, a roller brush 30 and a first motor 11. The table 9 is welded and fixed on the bottom beam of the frame 23 and is centrally arranged. A positioning hole for guiding the drill rod 13 is provided in the middle of the table 9. The rubber sleeve 26 is embedded in the positioning hole of the table 9. The rubber sleeve is a hard rubber sleeve. The drill rod 13 can pass through the rubber sleeve. On the one hand, the rubber sleeve guides the drill rod 13. On the other hand, when the drill rod 13 mixed in the foundation is lifted, the soil at the bottom of the drill rod 13 can be cleaned. In addition, the hard rubber sleeve has a self-lubricating effect during the interaction between the drill rod and the hard rubber sleeve. In other words, the rubber sleeve 26 is nested with the table 9 and slides with the drill rod.

[0025] Furthermore, the rubber sleeve may be a wear-resistant copper alloy sleeve, which can also play a role in cleaning the drill rod.

[0026] The support plate 31 is located below the bottom beam, and the support plate is mechanically connected to the table 9 through the support rod 27 to form a hanging installation platform. The first motor 11 is fixedly installed on the support plate 31. The first motor 11 is vertically arranged downward and a roller brush 30 is installed on the motor shaft. The first motor and the roller brush are used in a matching manner, and one on each side, and the drill rod is cleaned from two opposite directions. The roller brush acts on the drill rod, that is, the drill rod is cleaned, and the cleaning process is carried out with the rotation of the roller brush. Semicircular scrapers are arranged at the above-mentioned four support rods, that is, the semicircular scrapers 10 are welded and fixed on the support rods 27, and the number of the semicircular scrapers is two, and they are at different height positions, and the semicircular scrapers are arranged horizontally. Specifically, the support rods 27 are evenly distributed on the four corners of the table 9 to form a frame structure space. The ends of the semicircular scrapers 10 are mechanically connected to the support rods 27, and the semicircular scrapers 10 are arranged in stages in the space below the table 9. The first batch of semicircular scrapers 10 are welded and fixed to the two support rods 27 on the side, and the second batch of semicircular scrapers 10 are mechanically connected to the other two support rods 27, and the two semicircular scrapers directly act on the drill rod, respectively sliding or slightly matching the two side surfaces of the drill rod to clean the surface of the drill rod. The bottom of the support rod 27 is mechanically connected to the support plate 31, such as welded and fixed, and the first motor 11 installed on the support plate 31 drives the roller brush 30 to rotate, thereby realizing the cleaning and sweeping function of the soil at the bottom of the drill rod 13.

[0027] like Figure 4As shown, the roller brush 30 includes a chuck 28, a hard rubber rod 12 and a rubber ball 29. The chuck 28 of the roller brush 30 is mechanically connected to the main shaft of the first motor 11. A plurality of hard rubber rods 12 are connected around the chuck 28. A rubber ball 29 is arranged at the end of the hard rubber rod 12. The hard rubber rod 12 and the rubber ball 29 are injection molded. The presence of the rubber ball can increase the centrifugal effect of the roller brush and improve the impact effect when colliding with the drill rod. Specifically, the first motor 11 rotates to drive the roller brush 30 to rotate, and the roller brush 30 drives the hard rubber rod 12 and the rubber ball 29 to rotate. The soil at the bottom of the drill rod 13 is continuously struck by the plurality of hard rubber rods 12 and the rubber balls 29 on the rod, so that the soil or other impurities are separated from the drill rod 13.

[0028] like Figure 1-Figure 4 As shown, the vertical lifting mechanism A2 includes a guide rail 3, a buffer rope 24, a sleeve 5, a damping roller 1, a cylinder 8, a piston rod 7, a walking arm plate 21, a fixed bracket 34 and a guide sleeve 18, wherein the guide rail 3 is two circular guide columns, and the upper and lower ends of the guide rail 3 are welded and fixed to the top beam and the bottom beam to form two guide columns.

[0029] Two vertically arranged walking arm plates 21 and four connecting rods form a rectangular frame structure, wherein the four connecting rods are arranged horizontally. Specifically, the walking arm plate 21 has a certain width, a vertically arranged rectangular metal plate, and is connected at the upper and lower four corners of the vertically arranged rectangular plate by four connecting rods to form a frame structure. Four downwardly extending fixed brackets 34 are welded to the two lower connecting rods, and a guide sleeve plate 18 is mechanically fixed to the bottom of the fixed bracket 34. The guide sleeve plate 18 has a through hole for installing the drill rod 13, and the through hole is used to install a hard rubber sleeve and slide through the rubber sleeve and the upper section of the drill rod.

[0030] A sleeve 5 is welded and fixed on the outside of the above-mentioned walking wall plate, and the sleeve 5 is slidably connected to the guide rail 3, that is, the walking arm plate 21 has the ability and space for vertical displacement. The cylinder body of the cylinder 8 is hingedly connected to the table plate 9 on the frame 23, and the top of the piston rod 7 of the cylinder is hingedly connected to the guide sleeve 18 of the walking arm plate 21, that is, the cylinder drives the above-mentioned walking wall plate 21 to move up and down along the guide rail 3 in the height direction. At the same time, in this process, since the guide sleeve 18 is mechanically connected to the walking arm plate 21 through the fixed bracket 34, and the guide sleeve 18 is slidably connected to the drill rod 13, the vertical lifting device has a lifting action.

[0031] Furthermore, to ensure safety, a pair of damping rollers 1 are respectively provided on the top beam and the bottom beam, and a closed-loop buffer rope is installed on the damping roller between the top beam and the bottom beam. The buffer rope 24 is fixedly connected to the two connecting rods on the front side of the walking arm plate 21 by bundling, such as a steel hoop. The above-mentioned buffer ropes are respectively sleeved on the damping rollers 1 and embedded in the U-shaped grooves of the damping rollers 1, and are in a tensioned state. The U-shaped grooves of the damping rollers 1 are used to limit the buffer rope 24 to prevent the buffer rope 24 from detaching from the damping roller 1. The buffer rope 24 bypasses the damping roller 1 on the frame 23, and the buffer rope 24 forms a closed loop with the walking arm plate 21. The elasticity of the buffer rope is utilized to form a tensioning and buffering energy-absorbing effect on the walking arm plate. For example, when the hammer 6 hits the above-mentioned drill rod 13, the use of the buffer rope and the damping roller can reduce the adverse effects of the hammer and ensure the stability of the drill process.

[0032] The cylinder body of the cylinder 8 is installed on the table 9, and the piston rod 7 of the cylinder is hinged on the guide sleeve 18. When the cylinder 8 takes in air, it pushes the piston rod 7 to move upward, and when the cylinder 8 exhausts air, it pulls the piston rod 7 to move inward. Because the piston rod 7 is mechanically connected to the guide sleeve of the walking arm plate 21, when the cylinder 8 is inflated, the piston rod 7 pushes the walking arm plate 21 to move upward along the guide rail 3, thereby realizing the lifting function of the vertical lifting mechanism A2.

[0033] like Figure 1-Figure 3 As shown, the weight device A4 includes a second motor 15, a motor bracket 14, a steel wire rope 20, a pulley 22, a slider 17, a rocker arm 16, a chute 32 and a hammer body 6. The second motor 15 is mechanically connected to the frame 23 through the motor bracket 14, and the second motor 15 is mechanically connected to the rocker arm 16. The rocker arm 16 has a chute 32 passing through the axis. The chute 32 is a long strip structure. A limiting groove 33 is respectively arranged at both ends of the length direction of the chute. The limiting groove 33 is circular as a whole, and the size of the limiting groove 33 is slightly larger than the width of the chute 32. The slider 17 is slidably installed in the above-mentioned chute 32. When the second motor 15 drives the above-mentioned rocker arm 16 to rotate, every time it rotates 180 degrees and the steel wire rope is consistent with the direction of the chute, the slider has a rapid position conversion action. The above-mentioned chute and the slider are preferably T-shaped sliding fit, that is, the slider is a T-shaped slider.

[0034] The slider 17 is mechanically connected to the hammer 6 through a steel wire 20, that is, the steel wire 20 passes through a pulley 22 and is in contact with the pulley 22, the pulley 22 is rotatably mounted on one of the connecting rods, and the two ends of the steel wire are respectively fixedly connected to the hammer 6 and the slider 17. The second motor 15 is the power source of the heavy hammer device A4, and the hammer 6 is vertically arranged and located above the drill rod 13, and is maintained at a height value of 20 cm, that is, the stroke range of the hammer, for striking the drill rod 13, and the hammering action of the hammer 6 is mainly achieved by reciprocating motion in the vertical direction. The second motor 15 is fixed to the frame 23 through the motor bracket 14. One end of the wire rope 20 is connected to the hammer 6, and the other end is connected to the slider 17. The middle position of the wire rope 20 is mechanically connected to the pulley 22. The rocker arm 16, the slide 32, the slider 17, the wire rope 20, the hammer 6 and the limiting groove 33 are used together. The second motor 15 drives the rocker arm 16 to rotate. At this time, the slider 17 is in the limiting grooves 33 on both sides of the slide 32 and is temporarily locked. During the rotation of the rocker arm 16, the slider 17 and the wire rope 20 move with the rocker arm 16. When the rocker arm 16 and the direction of the slide groove 32 are consistent with the direction of the wire rope 20, the limiting constraint effect of the limiting groove 33 is reduced and the pulling force of the wire rope 20 acts together, and the slider 17 suddenly breaks away from the constraint of the limiting groove 33 and moves rapidly along the common direction of the slide groove 32 and the wire rope 20, and finally enters another limiting groove 33 arranged opposite the slide groove 32 of the rocker arm 16, completing the hammering action of the first hammer body 6. As the motor drives the rocker arm 16 to rotate further, it reciprocates to achieve a continuous, reciprocating hammering action.

[0035] like Figure 1-Figure 4 As shown, the data acquisition device A1 includes a single chip microcomputer 4, a photoelectric switch 25 and an ultrasonic distance sensor 2. The photoelectric switch 25 and the ultrasonic distance sensor 2 are electrically connected to the single chip microcomputer 4 respectively. The single chip microcomputer is fixed on the frame 23. The photoelectric switch 25 is mechanically connected to the vertical lifting mechanism A2. The ultrasonic distance sensor 2 is mechanically connected to the frame 23. Among them, the photoelectric switch 25 is installed on the fixed bracket 34 of the vertical lifting mechanism A2 and is horizontally arranged toward the hammer body, which is used to record the number of times the hammer body 6 hits the drill rod 13 and upload the measurement data signal to the single chip microcomputer 4. The ultrasonic distance sensor 2 is installed on the top beam of the frame 23, which is used to measure the descending distance of the vertical lifting mechanism A2 and upload the measurement data signal to the single chip microcomputer 4. The single chip microcomputer 4 is the control center and data storage center of the device. In order to improve the measurement accuracy of the ultrasonic distance sensor, a detection sheet is separately set on the walking arm plate 21 of the vertical lifting mechanism A2 to form a monitoring benchmark to ensure the accuracy of monitoring.

[0036] When the device is working, the motor drives the rocking arm 16 to rotate. At this time, the slider 17 is in the limiting grooves 33 on both sides of the slide slot 32. During the rotation of the rocking arm 16, the slider 17 and the wire rope 20 move together with the rocking arm 16. When the direction of the slide slot 32 of the rocking arm 16 is consistent with the direction of the wire rope 20, the limiting constraint effect of the limiting groove 33 is reduced and the pulling force of the wire rope 20 acts together, and the slider 17 suddenly breaks away from the limiting groove 33 and moves in the common direction of the slide slot 32 and the wire rope 20, and finally enters another limiting groove 33 arranged opposite the slide slot 32 of the rocking arm 16, completing the first hammer body 6 hammering action. As the motor drives the rocking arm 16 to rotate further, it reciprocates to realize continuous hammering action. The hammer body 6 hammers the drill rod 13. On the one hand, the drill rod 13 moves downward in the vertical direction under the hammering action of the hammer body 6, and the depth of the drill rod 13 inserted into the foundation gradually deepens.

[0037] In general, since the pulley 22 of the weight device A4 is mechanically connected to the walking arm plate 21 of the vertical lifting mechanism A2, and the drill rod 13 is mechanically connected to the positioning sleeve of the vertical lifting mechanism A2 through the positioning pin 19, the driving force of the vertical lifting mechanism A2 downward along the guide rail 3 is generated by the hammer body 6 of the weight device A4 hammering the drill rod 13, and the driving force of the vertical lifting mechanism A2 upward along the guide rail 3 is jointly generated by the cylinder 8 and the piston rod 7 of the vertical lifting mechanism A2. The power module is a single chip microcomputer 4, a photoelectric switch 25 and an ultrasonic The ultrasonic distance sensor 2 provides electrical energy, and the photoelectric switch 25 measures and records the number of times the hammer body 6 hits the drill rod 13 during the process of the hammer body 6 of the heavy hammer device A4 hammering the drill rod 13, and uploads the measurement data signal to the single-chip microcomputer 4. When the hammering action is completed, the ultrasonic distance sensor 2 measures the distance of the vertical lifting mechanism A2 descending by measuring the distance with the detection piece on the walking arm plate 21 of the vertical lifting mechanism A2, and uploads the measurement data signal to the single-chip microcomputer 4. The single-chip microcomputer 4 is the control center and storage center of this device.

[0038] The method of using the drilling probe is as follows: after completing the foundation calibration measurement point, the device is placed at the calibration measurement point, and then the cylinder is supplied with air, and the cylinder 8 pushes the piston rod 7 to move and then pushes the guide sleeve 18 into place. Since the guide sleeve 18 is a part of the vertical lifting mechanism A2, the vertical lifting mechanism A2 is pushed to move upward in the vertical direction along the guide rail 3. At this time, the positioning pin 19 of the drill rod 13 contacts the guide sleeve 18 and has a top constraint on the drill rod. Under the action of the guide sleeve 18, the drill rod 13 is further lifted, the first motor is powered and the second motor is powered, and the motor drives the rocker arm 16 to rotate. At this time, the slider 17 is in the limiting grooves 33 on both sides of the slide slot 32, and the rocker arm 16 slides during the rotation. The block 17 and the wire rope 20 move together with the rocker arm 16. When the direction of the slide groove 32 of the rocker arm 16 is consistent with the direction of the wire rope 20, the limiting constraint effect of the limiting groove 33 is reduced and the pulling force of the wire rope 20 acts together, and the slider 17 suddenly breaks away from the limiting groove 33 and moves along the common direction of the slide groove 32 and the wire rope 20, and finally enters another limiting groove 33 arranged opposite the slide groove 32 of the rocker arm 16, completing the first hammering action of the hammer body 6. As the motor drives the rocker arm 16 to rotate further, it reciprocates to realize continuous hammering action. The hammer body 6 hammers the drill rod 13. On the one hand, the drill rod 13 moves downward in the vertical direction under the hammering action of the hammer body 6, and the depth of the drill rod 13 inserted into the foundation gradually deepens. At the same time, the first motor 11 of the cleaning device drives the hard rubber rod 12 and the rubber ball 29 to rotate, and the rotation of the first motor 11 drives the roller brush 30 to rotate, and the roller brush 30 drives the hard rubber rod 12 and the rubber ball 29 on the rod to rotate, and the soil at the bottom of the drill rod 13 is continuously struck by multiple hard rubber rods 12 and the rubber balls 29 on the rod, so that the soil or other impurities are separated from the drill rod 13. Semicircular scrapers 10 are arranged in stages on the lower part of the table 9. The semicircular scrapers 10 of the first stage and the semicircular scrapers 10 of the second stage are arranged relatively to each other, and a full-circle scraper can be formed in the horizontal direction. The scraper performs secondary cleaning of the soil at the bottom of the drill rod 13. The rubber sleeve 26 on the table 9 is made of flexible material, and the size of the rubber sleeve is slightly smaller than the diameter of the drill rod 13, which is equivalent to the interference fit in the mechanical structure, further improving the cleaning effect of the soil at the bottom of the drill rod 13. In the above process, the photoelectric switch 25 measures and records the number of times the hammer body 6 of the heavy hammer device A4 hits the drill rod 13 and uploads the measurement data signal to the single-chip microcomputer 4. When the hammering action is completed, the ultrasonic distance sensor 2 measures the distance of the vertical lifting mechanism A2 descending by measuring the distance with the detection plate on the walking arm plate 21 of the vertical lifting mechanism A2 and uploads the measurement data signal to the single-chip microcomputer 4. The single-chip microcomputer 4 is the control center and storage center of this device.
