Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, specifically a core sampling device for detecting the carbonation depth of concrete components. Background Technology

[0002] When testing the carbonation depth of concrete components, phenolphthalein alcohol solution is usually used. First, the worker chisels a conical pit with a depth of more than 6mm into the concrete surface, and then drips phenolphthalein alcohol solution onto the inner wall. When the boundary between carbonation and non-carbonation is clear, the vertical distance from the boundary to the concrete surface is measured, which is the carbonation depth. On the construction site, this often requires a worker to specially chisel the pit, which is very physically demanding, slow, and the shape of the chiseled pit is also very random, which will affect the measurement of carbonation depth and the aesthetics of the component surface.

[0003] Chinese patent CN221445466U discloses a portable concrete sampling device, including a base plate and a sampling mechanism. The sampling mechanism is located above the base plate and includes a lead screw, a support assembly, a drilling assembly, and a drill bit positioning assembly. A lead screw is fixedly connected to one side of the top of the base plate. A support assembly is located on one side of the lead screw. The drilling assembly is located inside the support assembly, and the drill bit positioning assembly is located outside the drilling assembly. An inner cavity is formed inside the lead screw, and an inner lead screw is located inside the inner cavity. The top of the inner lead screw... The system includes a connecting rod fixedly connected to one end, a crank fixedly connected to the top of the connecting rod, a support assembly including a top plate, a front support plate, and a positioning rod, a top plate fixedly connected to the top of the lead screw, a front support plate fixedly connected to one side of the top plate, and a positioning rod fixedly connected to the bottom of the top plate, and a drilling assembly including a motor, a connecting chamber, a drill bit, a water inlet, and a water outlet, a motor located inside the top plate, a connecting chamber fixedly connected to the bottom of the motor, a drill bit located below the connecting chamber, a water inlet located on one side of the connecting chamber, and a water outlet located inside the drill bit.

[0004] However, the technical solution of this patent has the following problems:

[0005] This patent cannot automatically drill deeper, nor can it automatically eject the core sample while the drill bit resets to drill the next position.

[0006] Therefore, those skilled in the art have provided a core sampling device for detecting the carbonation depth of concrete components to solve the above-mentioned problems. Utility Model Content

[0007] The purpose of this invention is to provide a core sampling device for detecting the carbonation depth of concrete components, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A core sampling device for detecting the carbonation depth of concrete components includes a housing, and further includes a drilling mechanism and an automatic material ejection mechanism. The drilling mechanism is installed on the left side of the housing, and the automatic material ejection mechanism is installed on the right side of the housing. The drilling mechanism includes a guide rail, a slider, a moving plate, and a drill bit. Two guide rails are fixedly installed on the lower side of the housing. The slider is slidably connected to the guide rails. The moving plate is fixedly installed on the slider. The drill bit is rotatably connected to the moving plate. The left side of the drill bit is hollow, and the right side of the drill bit has a hexagonal through hole.

[0010] Furthermore, the automatic unloading mechanism includes: a middle side plate and a hexagonal rod. The middle side plate is fixedly installed on the middle side of the housing. The right side of the hexagonal rod is rotatably connected to the middle side plate, and the left side of the hexagonal rod is slidably connected to the hexagonal through hole on the right side of the drill bit.

[0011] Furthermore, a drive motor is fixedly installed on the right side of the housing, and the output shaft of the drive motor is fixedly connected to the right side of the hexagonal rod;

[0012] Furthermore, the automatic unloading mechanism also includes a linkage mechanism, which is installed on the lower side of the housing.

[0013] Furthermore, the linkage mechanism includes a threaded rod and a threaded block. The left side of the threaded rod is rotatably connected to the left side of the housing, and the right side of the threaded rod is rotatably connected to the lower side of the middle side plate. The threaded block is fixedly installed on the lower side of the movable plate and is threadedly connected to the threaded rod.

[0014] Furthermore, the linkage mechanism also includes: a main synchronous pulley, a secondary synchronous pulley, and a synchronous belt. The main synchronous pulley is fixedly mounted on the output shaft of the drive motor, the secondary synchronous pulley is fixedly mounted on the right side of the threaded rod, and the synchronous belt is connected to the main synchronous pulley and the secondary synchronous pulley.

[0015] Furthermore, a dust cover is fixedly installed on the left side of the housing, and a dustproof rubber ring is fixedly installed on the right side of the dust cover;

[0016] Furthermore, a miniature vacuum cleaner is fixedly installed on the lower side of the housing, and the output end of the miniature vacuum cleaner is fixedly connected to the lower side of the dust cover through a pipe.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model drives the hexagonal rod to rotate by rotating the output shaft of the drive motor, which in turn drives the drill bit to rotate. The output shaft of the drive motor drives the main synchronous pulley to rotate, which in turn drives the auxiliary synchronous pulley to rotate via the synchronous belt. The auxiliary synchronous pulley then drives the threaded rod to rotate, which in turn allows the threaded block to move left and right. The left and right movement of the threaded block drives the moving plate to move left and right, which in turn drives the drill bit to move left and right. This allows the drive motor to drive the drill bit to rotate while simultaneously driving the drill bit to move left and right, achieving automatic deep drilling and improving drilling efficiency. When the hole reaches a depth approximately 5mm beyond the preset depth, the device is shaken up and down or back and forth to make the drill bit shake inside the hole, and the core sample breaks off and remains inside the drill bit. After drilling and sampling are completed, the moving plate moves to the right, driving the drill bit and core sample to move to the right. The drill bit moves to the right on the hexagonal rod, which remains stationary, pushing out the core sample from the drill bit. This achieves drill bit reset and allows drilling to proceed to the next position while automatically pushing out the core sample.

[0018] 2. The contact area between the drill bit and the concrete component is sealed by a dust cover, and the drilled dust falls into the dust cover. The dustproof rubber ring is used to seal the gap between the drill bit and the housing, so that the dust does not fall into the housing. The mini vacuum cleaner is activated and sucks away the dust in the dust cover through the pipe, realizing dust removal at the same time as drilling. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0027] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-5 A core sampling device for detecting the carbonation depth of concrete components includes a housing 1, and further includes a drilling mechanism 2 and an automatic material ejection mechanism 3. The drilling mechanism 2 is installed on the left side of the housing 1, and the automatic material ejection mechanism 3 is installed on the right side of the housing 1. The drilling mechanism 2 includes a guide rail 21, a slider 22, a moving plate 23, and a drill bit 24. The two guide rails 21 are fixedly installed on the lower side of the housing 1. The slider 22 is slidably connected to the guide rails 21. The moving plate 23 is fixedly installed on the slider 22. The drill bit 24 is rotatably connected to the moving plate 23. The left side of the drill bit 24 is hollow, and the right side of the drill bit 24 has a hexagonal through hole 25.

[0028] Drilling mechanism 2 drills holes to sample concrete components, and automatic ejection mechanism 3 automatically ejects the core sample from drill bit 24. Spraying phenolphthalein alcohol solution on the core sample allows for direct measurement of the carbonation depth of the component, and also allows for sample preservation, which is convenient for later traceability.

[0029] The drill bit 24 of the drilling mechanism 2 rotates, and at the same time the moving plate 23 moves to the left. The guide rail 21 and the slider 22 limit the left and right movement of the moving plate 23. The leftward movement of the moving plate 23 drives the rotating drill bit 24 to move to the left, drilling a hole in the concrete component. When the hole is drilled to a depth of about 5mm beyond the preset depth, the device is shaken up and down or back and forth, causing the drill bit 24 to shake inside the hole, and the core sample is broken off and left inside the drill bit 24.

[0030] The automatic unloading mechanism 3 includes a middle side plate 31 and a hexagonal rod 32. The middle side plate 31 is fixedly installed on the middle side of the housing 1. The right side of the hexagonal rod 32 is rotatably connected to the middle side plate 31, and the left side of the hexagonal rod 32 is slidably connected to the hexagonal through hole 25 on the right side of the drill bit 24.

[0031] After drilling and sampling are completed, the moving plate 23 moves to the right, driving the drill bit 24 and the core sample to the right. The drill bit 24 moves to the right on the hexagonal rod 32, while the hexagonal rod 32 remains stationary, pushing out the core sample inside the drill bit 24. This allows the drill bit 24 to reset and drill at the next position while the core sample is automatically pushed out.

[0032] Example 2: In some embodiments, such as Figures 1-5 In a preferred embodiment of the present invention, a drive motor 33 is fixedly installed on the right side of the housing 1, and the output shaft of the drive motor 33 is fixedly connected to the right side of the hexagonal rod 32.

[0033] The output shaft of the drive motor 33 rotates, causing the hexagonal rod 32 to rotate, and the rotation of the hexagonal rod 32 causes the drill bit 24 to rotate.

[0034] The automatic unloading mechanism 3 also includes a linkage mechanism, which is installed on the lower side of the housing 1.

[0035] The linkage mechanism includes a threaded rod 34 and a threaded block 35. The threaded rod 34 is rotatably connected to the left side of the housing 1 on the left side and rotatably connected to the lower side of the middle side plate 31 on the right side. The threaded block 35 is fixedly installed on the lower side of the movable plate 23 and is threadedly connected to the threaded rod 34.

[0036] The linkage mechanism further includes a main synchronous pulley 36, a secondary synchronous pulley 37, and a synchronous belt 38. The main synchronous pulley 36 is fixedly mounted on the output shaft of the drive motor 33, the secondary synchronous pulley 37 is fixedly mounted on the right side of the threaded rod 34, and the synchronous belt 38 is connected to the main synchronous pulley 36 and the secondary synchronous pulley 37.

[0037] The output shaft of the drive motor 33 rotates, causing the main synchronous pulley 36 to rotate. The rotation of the main synchronous pulley 36 drives the auxiliary synchronous pulley 37 to rotate via the synchronous belt 38. The rotation of the auxiliary synchronous pulley 37 drives the threaded rod 34 to rotate. The rotation of the threaded rod 34 allows the threaded block 35 to move left and right. The left and right movement of the threaded block 35 drives the moving plate 23 to move left and right. The left and right movement of the moving plate 23 drives the drill bit 24 to move left and right. This allows the drive motor 33 to drive the drill bit 24 to rotate while simultaneously driving the drill bit 24 to move left and right, achieving automatic deep drilling and improving drilling efficiency.

[0038] A dust cover 4 is fixedly installed on the left side of the housing 1, and a dustproof rubber ring 5 is fixedly installed on the right side of the dust cover 4.

[0039] A miniature vacuum cleaner 6 is fixedly installed on the lower side of the housing 1, and the output end of the miniature vacuum cleaner 6 is fixedly connected to the lower side of the dust cover 4 through a pipe 7.

[0040] The dust cover 4 seals the contact area between the drill bit 24 and the concrete component, and the drilled dust falls into the dust cover 4. The dustproof rubber ring 5 is used to seal the gap between the drill bit 24 and the housing 1, so that the dust will not fall into the housing 1. The mini vacuum cleaner 6 is activated to absorb the dust in the dust cover 4 through the pipe 7, thus realizing dust removal while drilling.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
