Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of material detection, and more specifically relates to an automatic needle insertion control device for intelligently controlling a cement detector. BACKGROUND

[0002] With the rapid development of the construction industry, as an important basic material, the performance detection requirements of cement are increasingly stringent. The quality of cement directly affects the safety and durability of buildings, so it is particularly important to ensure the accuracy and reliability of cement detection. However, the existing cement detector often faces the problem of inaccurate falling position during probe insertion. This phenomenon not only leads to unstable detection results, but also may cause serious misjudgment of cement quality evaluation.

[0003] In actual operation, if the insertion depth and angle of the probe are not accurate, it will directly affect the authenticity and effectiveness of the measurement data. For example, if the probe fails to penetrate to the predetermined depth of the cement sample, it may result in a low measurement result, while excessive depth may cause damage to the probe or interference to the sample. As can be seen, accurate insertion of the probe is crucial to obtain reliable detection results.

[0004] In addition, with the increasing complexity of construction engineering, the demand for multi-dimensional detection of cement performance is also increasing.

Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

The lifting device includes a first motor 1, a sliding block 2, a lead screw 9, a second connecting piece 4. The first motor 1 is fixedly connected to the base 10, the first motor 1 drives the lead screw 9 to rotate, the lead screw 9 is screwed to the second connecting piece 4, the second connecting piece 4 is fixedly connected to the sliding block 2, and the sliding block 2 is slidingly connected to the base 10. The first motor 1 rotates to drive the lead screw 9 to rotate, and the lead screw 9 drives the second connecting piece 4 and the sliding block 2 to move up and down. The first guide seat 12 and the second guide seat 19 are both fixedly installed on the base 10, the guide column 13 passes through the first guide seat 12 and the second guide seat 19 and is slidingly connected to the two seats. 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. 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 provided to increase detection accuracy.

[0028] As shown in Figure 2 , 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 8, and a second motor (not shown in the drawing). The upper connecting plate 18 and the lower connecting plate 7 are located on the upper and lower sides of the second connecting piece 4 and are connected together by bolts. The first connecting piece 3 fixedly connects the upper connecting plate 18 and the sliding block 2 together by bolts. The base 10 is provided with a vertical sliding rail. The first motor 1 rotates to drive the lead screw 9 to rotate, and the lead screw 9 is screwed to the sliding block 2, so that the sliding block 2 moves up and down along the sliding block under the drive of the first motor 1. The first connecting piece 3, the upper connecting plate 18, and the lower connecting plate 7 all have circular holes, and the lead screw 9 passes through the circular holes, and the diameter of the lead screw 9 is smaller than the diameter of the circular holes.

[0029] The second motor is installed on the lower connecting plate 7, and the second motor drives the first transmission wheel 5 to rotate. The first transmission wheel 5 and the second transmission wheel 16 are drivingly connected by the 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] As shown in Figure 5 , the clamping mechanism 17 includes a limiting shaft 1701 and a rubber ring 1702. The limiting shaft 1701 is a stepped shaft, and the diameters of the two end shaft heads are smaller than the diameter of the middle part. The rubber ring 1702 is wound around the middle position of the limiting shaft 1701. The clamping mechanism 17 has three, which are arranged inside the second transmission wheel 16 and are evenly distributed around the guide column 13.

[0031] As Figures 6-7 shown, the upper connecting plate 18 is provided with three second sliding grooves 1801, and the lower connecting plate 7 is provided with three first sliding grooves 701. Three limiting grooves 1601 are arranged on both sides of the second transmission wheel 16. The distance between the limiting grooves (1601) and the second transmission wheel 16 is gradually changed. The upper end of the limiting shaft 1701 is clamped in the limiting grooves 1601 and the second sliding grooves 1801 above the shell 1602, and the lower end is clamped in the limiting grooves 1601 and the first sliding grooves 701 above the cover plate 1603.

When the clamping mechanism 17 clamps the guide column 13, the rubber ring 1702 is in contact with the guide column 13 and is extruded.

The light shielding ring 14 is sleeved and connected to the guide column 13. The light shielding ring 14 is provided with a side wall, and the photoelectric switch 15 is a groove type. During the up-and-down movement of the guide column 13, the side wall of the light shielding ring 14 extends into the groove of the photoelectric switch 15, and triggers the photoelectric switch 15.

[0033] The working process of the control device is as follows: during detection, first, the first motor 1 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 surface of the cement, then the first motor 1 reversely rotates to drive the clamping device and the probe 11 to ascend 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 loosens the guide column 13, the guide column 13 falls downward under the action of gravity until the probe 11 extends below the surface of the cement, and when the circuit is connected, the probe has been inserted into the cement and the next operation can be continued; the first motor 1 controls the clamping device to descend, at this time, the clamping device is in a loosened state, and the photoelectric switch 15 descends with the clamping device, and when the light shielding ring 14 above the guide column 13 triggers the photoelectric switch 15, the clamping device stops descending, the second motor drives the second transmission wheel 16 to rotate, so that the clamping mechanism 17 approaches and clamps the guide column 13, and the first motor 1 controls the clamping device to ascend, and when a cylindrical standard functional inductive sensor 20 installed on the base 10 is triggered, the clamping device returns to the initial position, waiting for the next round of detection.

[0034] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
