Description

Technical Field

[0001] The invention belongs to the technical field of material detection, and more specifically, relates to an automatic pin insertion control device for an intelligently controlled cement detector. Background Art

[0002] With the rapid development of the construction industry, cement, as an important basic material, has increasingly stringent requirements for performance testing. The quality of cement directly affects the safety and durability of buildings. Therefore, it is particularly important to ensure the accuracy and reliability of cement testing. However, existing cement detectors often face the problem of inaccurate falling positions during the probe insertion process. This phenomenon not only leads to unstable test results, but may also cause serious misjudgment of cement quality assessment.

[0003] In actual operation, if the insertion depth and angle of the probe are inaccurate, it will directly affect the authenticity and validity of the measurement data. For example, if the probe fails to penetrate into the predetermined depth of the cement sample, it may lead to a low measurement result, while if it is too deep, it may damage the probe or interfere with the sample. Therefore, accurate insertion of the probe is crucial to obtain reliable test results.

[0004] In addition, as the complexity of construction projects increases, the demand for multi-dimensional testing of cement performance is also increasing. Traditional testing instruments mostly rely on manual operation, which cannot meet the requirements of high efficiency and high precision, and increases the risk of human error. Therefore, there is an urgent need for an innovative automatic pin control method to improve the accuracy and work efficiency of cement testing through intelligent technology.

Through this precisely controlled clamping and releasing mechanism, the stability and flexibility of the probe in various operation stages can be guaranteed.

[0017] 2. In this application, a slot-type photoelectric switch and a light-shielding ring are used to monitor and control the movement and position of the probe. When the probe is in motion, the side wall of the light-shielding ring will enter the detection area of ​​the photoelectric switch as the guide column moves. The light-shielding ring will block the light beam of the photoelectric switch when entering the detection area, thereby triggering a signal and feeding back to the control system. Based on these feedback signals, the control system can accurately control the movement of the probe, continuously capture the speed and displacement changes of the probe, including its rise, fall, and final positioning, and ensure that the operation path of the probe is within the set parameter range, greatly improving the system's automation control accuracy and reliability.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] like Figure 1-2As shown, the automatic needle insertion control device includes a base 10, a lifting device, a clamping device, a guide column 13, a probe 11, a photoelectric switch 15, a shading ring 14, a first guide seat 12, and a second guide seat 19. The lifting device includes a first motor 1, a slider 2, a lead screw 9, and a second connecting member 4. The first motor 1 is fixedly connected to the base 10, and the first motor 1 drives the lead screw 9 to rotate. The lead screw 9 is screwed to the second connecting member 4, and the second connecting member 4 is fixedly connected to the slider 2, and the slider 2 is slidably connected to the base 10. The first motor 1 rotates, driving the lead screw 9 to rotate, and the lead screw 9 drives the second connecting member 4 and the slider 2 to rise and fall. The first guide seat 12 and the second guide seat 19 are both fixedly mounted on the base 10, and the guide column 13 passes through the first guide seat 12 and the second guide seat 19 and is slidably connected to the two supports. The probe 11 is fixedly connected to the lower end of the guide column 13. The guide column 13 can slide up and down along the first guide seat 12 and the second guide seat 19 under the action of gravity or external force, thereby driving the light shielding ring 14 to slide up and down together, and the light shielding ring 14 can trigger the photoelectric switch 15, and the photoelectric switch 15 controls the clamping mechanism to clamp or release the guide column 13. Two photoelectric switches 15 can be set to increase the detection accuracy.

[0028] like Figure 2 As shown, the clamping device includes a clamping mechanism 17, a first transmission wheel 5, a second transmission wheel 16, a transmission belt 6, an upper connecting plate 18, a lower connecting plate 7, a support member 8, and a second motor (not shown in the drawing). The upper connecting plate 18 and the lower connecting plate 7 are respectively located on the upper and lower sides of the second connecting member 4 and are connected to each other by bolts. The first connecting member 3 fixes the upper connecting plate 18 and the slider 2 together by bolts. A vertical slide rail is provided on the base 10. The first motor 1 rotates to drive the lead screw 9 to rotate. The lead screw 9 is screwed to the slider 2 by threads. Therefore, the slider 2 moves up and down along the slider under the drive of the first motor 1. There are circular holes on the first connecting member 3, the upper connecting plate 18, and the lower connecting plate 7. The lead screw 9 passes through the circular hole and the diameter of the lead screw 9 is smaller than the diameter of the circular hole.

[0029] The second motor is mounted on the lower connecting plate 7, and the second motor drives the first transmission wheel 5 to rotate. The first transmission wheel 5 is connected to the second transmission wheel 16 through a transmission belt 6. Here, the transmission belt 6 is a steel belt, which is fixedly connected to the first transmission wheel 5 and the second transmission wheel 6 by bolts. The guide column 13 passes through the center of the second transmission wheel 16. The second transmission wheel 16 is placed between the upper connecting plate 18 and the lower connecting plate 7.

[0030] like Figure 5 As shown, the clamping mechanism 17 includes a limiting shaft 1701 and a rubber ring 1702. The limiting shaft 1701 is a stepped shaft, and the diameter of the shaft ends at both ends is smaller than the middle diameter. The rubber ring 1702 is wound around the middle position of the limiting shaft 1701. There are three clamping mechanisms 17, which are arranged inside the second transmission wheel 16 and evenly distributed around the guide column 13.

[0031] like Figure 6-7 As shown, the upper connecting plate 18 is provided with three second slide grooves 1801, and the lower connecting plate 7 is provided with three first slide grooves 701. Three limiting grooves 1601 are respectively provided on both sides of the second transmission wheel 16. The distance between the limiting groove (1601) and the second transmission wheel 16 is gradually changed. The shaft head at the upper end of the limiting shaft 1701 is clamped in the limiting groove 1601 and the second slide groove 1801 on the housing 1602, and the shaft head at the lower end is clamped in the limiting groove 1601 and the first slide groove 701 on the cover plate 1603. When the second motor drives the second transmission wheel 16 to rotate, the limiting shaft 1701 slides in the first slide groove 701 and the second slide groove 1801, and slides in the limiting groove 1601, so that the clamping mechanism 17 completes the action of approaching and moving away from the guide column 13, thereby completing the clamping and loosening of the guide column 13. When the clamping mechanism 17 clamps the guide column 13, the rubber ring 1702 contacts and squeezes the guide column 13.

[0032] The photoelectric switch 15 is fixedly connected to the lower surface of the lower connecting plate 7 and is close to the guide post 13. The light shielding ring 14 is sleeved and connected to the guide post 13. The light shielding ring 14 is provided with a circle of side walls, and the photoelectric switch 15 is groove-shaped. When the guide post 13 is lifted up and down, the side wall of the light shielding ring 14 extends into the groove of the photoelectric switch 15, triggering the photoelectric switch 15.

[0033] The working process of the control device is as follows: during detection, the first motor 1 first drives the lead screw 9 to rotate, the lead screw 9 drives the second connecting piece 4 and the entire clamping device to descend, the clamping device drives the probe to descend from the initial position to the cement surface, then the first motor 1 rotates in the opposite direction, driving the clamping device and the probe 11 to rise by one millimeter; then, the second motor drives the second transmission wheel 16 to rotate, so that the clamping mechanism 17 moves away from and releases the guide column 13, the guide column 13 falls downward under the action of gravity until the probe 11 extends below the cement surface, and the conductive principle of the guide column 13, the probe 11 and the cement is used. When the circuit is connected, the probe has been inserted into the cement and the next operation can be carried out; the first motor 1 controls the clamping device to descend, and the clamping device is in a loosened state at this time. The photoelectric switch 15 descends with the clamping device. When the light shielding ring 14 on the guide column 13 triggers the photoelectric switch 15, the clamping device stops descending, and the second motor drives the second transmission wheel 16 to rotate, so that the clamping mechanism 17 approaches and clamps the guide column 13. The first motor 1 controls the clamping device to rise, and when the cylindrical standard functional inductive sensor 20 installed on the base 10 is triggered, it returns to the initial position and waits for the next round of detection.

[0034] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
