Description

Technical Field

[0001] The invention relates to the technical field of floor thickness detection, and in particular to a floor thickness detection device which is convenient for adjusting and aligning. Background Art

[0002] Floor thickness detection is an important part of construction project quality control. Ensuring that the thickness of the floor meets the design requirements is crucial to structural safety and building performance. Common floor thickness detection methods include: core drilling method, rebound test, ultrasonic thickness gauge, etc. Among them, the detection structure obtained by the core drilling method is the most accurate.

[0003] When using the core drilling method for detection, first determine the core drilling position and clearly mark it. Use a special concrete core drilling machine to drill a cylindrical concrete core sample of a certain specification at the selected position on the floor slab, and then measure the thickness of the core sample to obtain the thickness of the floor slab. When using a core drilling machine, the drill is usually fixed at the core drilling position by a top rod support. However, since the flatness of the floor slab surface cannot be ensured, it is impossible to ensure that the axis of the drill bit is perpendicular to the surface of the concrete floor slab after the support frame of the core drilling machine contacts the floor slab. If the drill bit is not perpendicular to the concrete floor slab, the thickness detection of the core drilling will be inaccurate; secondly, a single top rod support is difficult to withstand various stresses during the drilling process, and the stability during the core drilling process needs to be improved; thirdly, in the quality control link of the construction project, it is necessary to frequently move the equipment at different locations or to perform floor slab thickness detection in an environment with limited space. The portability of the existing core drilling machine needs to be improved.

[0004] Therefore, in order to ensure the accuracy of the thickness of the core drill and improve the stability and convenience of the core drill, the present invention provides a floor thickness detection device that is easy to adjust and align. Summary of the invention

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Referring to Figure 1 and Figure 2 , a floor thickness detection device convenient for adjusting alignment includes a sleeve 1 and a stabilizing mechanism 5. The sleeve 1 has an opening facing downward, and a positioning mechanism 2, a core drilling mechanism 3, a disassembly and assembly mechanism 4, and a horizontal verification piece 6 are arranged on the sleeve 1. A stabilizing mechanism 5 is arranged on the disassembly and assembly mechanism 4. The horizontal verification piece 6 is composed of an inverted L-shaped grip and a slider fixed to the bottom wall of the inverted L-shaped grip. A slide rail for the horizontal section of the inverted L-shaped grip and the slider of the horizontal verification piece 6 to slide is opened on the lower part of the side wall of the sleeve 1.

[0035] Referring to Figure 1 , Figure 2 , Figure 4 and Figure 5, the positioning mechanism 2 includes a support ring 21 and a positioning component 22 for alignment before core drilling. The lower part of the inner wall of the sleeve 1 is fixedly connected with the support ring 21, and the positioning component 22 is jointly arranged on the support ring 21 and the sleeve 1; the positioning component 22 includes an arc-shaped piece 221. The bottom wall of the support ring 21 is symmetrically connected with the arc-shaped piece 221 through a first spring (not shown in the figure) in a sliding manner. An inverted conical groove is formed on the top walls of the two arc-shaped pieces 221. The outer walls of the two arc-shaped pieces 221 away from each other are fixedly provided with balance rods 222 that slide through the side wall of the sleeve 1. The bottom wall of the arc-shaped piece 221 is connected with a positioning piece 223 through a second spring in a vertical sliding manner.

[0036] Refer to Figures 2 to 3 , the core drilling mechanism 3 includes a core drill 34 for core drilling operations, a hydraulic cylinder 31 for pushing the core drill downward, a balance component 32 for maintaining stability during core drilling, and a motor 33 for driving the core drill 34 to rotate; the inner top wall of the sleeve 1 is provided with the hydraulic cylinder 31. The balance component 32 includes a support seat 322. The bottom wall of the output end of the hydraulic cylinder 31 is fixedly connected with the support seat 322. A plurality of positioning holes 323 are formed in the top wall of the support seat 322 along the circumferential direction. A plurality of stabilizing rods 321 corresponding to the positioning holes 323 are fixedly arranged on the inner top wall of the sleeve 1. A motor 33 is installed inside the support seat 322, and the bottom wall of the output end of the motor 33 is fixedly provided with a core drill 34 that is rotatably connected to the bottom wall of the support seat 322.

[0037] First, clearly mark the center position of the drilling hole on the surface of the floor slab to be detected in thickness with chalk or other means. Lift the assembled equipment and place it on the surface of the floor slab to be detected in thickness, so that the bottom of the positioning piece 223 is aligned with the marked center position of the drilling hole. The positioning piece 223 is located directly below the core drill 34, ensuring the accuracy of subsequent core drilling. As the equipment is lowered, the second spring is compressed, and the positioning piece 223 enters the inside of the arc-shaped piece 221. The bottom wall of the sleeve 1 is attached to the floor slab to facilitate preliminary positioning.

[0038] Before core drilling, the output end of the hydraulic cylinder 31 drives the support seat 322 to move downward. The support seat 322 slides downward along the outer wall of the stabilizing rod 321. The stabilizing rod 321 limits the position to maintain the balance of the support seat 322 during downward movement. When the support seat 322 drives the core drill 34 to move downward, the core drill 34 slides downward along the inclined top wall of the arc-shaped piece 221. The bottom wall of the core drill 34 pushes the two arc-shaped pieces 221 to slide away from each other on the bottom wall of the support ring 21. The first spring is compressed, and the balance rods 222 slide through the side wall of the sleeve 1 from the inside to the outside to maintain the stability of the arc-shaped piece 221 during movement; when the core drill 34 moves downward to the position between the two arc-shaped pieces 221, the bottom wall of the core drill 34 contacts the position of the floor slab to be detected in thickness. Ball bearings are arranged on the side walls of the two arc-shaped pieces 221 and the two positioning pieces 223 close to each other to reduce the friction force between the side wall of the core drill 34.

[0039] Reference Figure 1 、 Figure 6 and Figure 7 ,the disassembly and assembly mechanism 4 includes a quick-disassembly component one 41 and a quick-disassembly component two 42 that cooperate with each other to quickly disassemble and assemble the sleeve 1; the quick-disassembly component one 41 includes a connecting seat one 411 fixed to the top wall of the sleeve 1. In the middle of the top wall of the connecting seat one 411, a round rod 412 is fixedly connected. On the top wall of the round rod 412, a frustum part one 413 is fixedly connected. A frustum part two 414 that is the same size as the frustum part one 413 and symmetrically arranged up and down is slidably sleeved on the outer wall of the round rod 412.

[0040] Reference Figure 1 、 Figure 6 and Figure 7 ,the quick-disassembly component two 42 includes a connecting seat two 421. A connecting seat two 421 is arranged directly above the connecting seat one 411. A groove for the round rod 412, the frustum part one 413 and the frustum part two 414 to enter is opened on the bottom wall of the connecting seat two 421. Inside the connecting seat two 421, two limit parts 422 are symmetrically connected by springs three on the left and right. The limit part 422 is composed of a connecting seat connected to the connecting seat two 421 by a spring three and a wedge block fixed to the side wall of the connecting seat. The bottom wall of the wedge block of the limit part 422 is in an inclined shape adapted to the side wall of the frustum part one 413. A U-shaped gasket 423 is snap-connected to the outer wall of the round rod 412.

[0041] Reference Figure 1 and Figure 8 ,the stabilizing mechanism 5 includes a connecting component one 51, a connecting component two 52, a support rod member 53, an alignment component 54 and a stabilizing component 55; a connecting component one 51 and a connecting component two 52 are arranged on the connecting seat two 421. The connecting component one 51 includes a connecting rod 511. The connecting rod 511 is symmetrically and fixedly connected to the left and right sides of the connecting seat two 421. A rotating seat one 512 is hinged to the side wall of each of the two connecting rods 511 away from each other. An inverted L-shaped plate 513 is fixed to the top wall of each of the two ends of the two connecting rods 511 away from each other. The vertical section of the inverted L-shaped plate 513 is connected to the rotating seat one 512 by a pin.

[0042] Reference Figure 1 and Figure 8 ,the connecting component two 52 includes a T-shaped seat 521. A T-shaped seat 521 is rotatably connected to the top wall of the connecting seat two 421. A rotating seat two 522 is hinged to each of the left and right ends of the horizontal section of the T-shaped seat 521. A cross plate 523 is fixedly connected to the side wall of each of the two rotating seats two 522 close to each other. The cross plate 523 is connected to the T-shaped seat 521 by a pin.

[0043] Reference Figure 1 、 Figure 8 and Figure 9, detachable support rods 53 are fixed to the bottom walls of the first rotating base 512 and the second rotating base 522. Specifically, the support rods 53 and the first rotating base 512 and the second rotating base 522 can be connected by existing clamping components or by bolts. An alignment component 54 is provided on the support rod 53. The alignment component 54 includes a first rack 542. The first rack 542 is slidably connected up and down inside the support rod 53 through a fourth spring. A disc seat 541 is fixedly connected to the bottom wall of the first rack 542. A release block 543 is slidably penetrated through the side wall of the support rod 53 through a fifth spring; a second rack 544 is fixedly connected to one side of the release block 543 located inside the support rod 53. The outer walls of the adjacent sides of the first rack 542 and the second rack 544 are both serrated and meshed with each other. The serrated outer walls of the first rack 542 and the second rack 544 are both composed of multiple inclined surfaces and multiple horizontal surfaces alternatingly.

[0044] Refer to Figure 1 and Figure 8 , a stabilizing component 55 is jointly provided on the second connecting seat 421 and the T-shaped seat 521. The stabilizing component 55 includes a hinge seat 551. The top wall of the hinge seat 551 and the bottom walls on the left and right sides of the horizontal section of the T-shaped seat 521 are both rotatably connected with the hinge seat 551. A spring rod 552 is hinged between the correspondingly upper and lower hinge seats 551. A positioning pin 553 is jointly clamped and connected between the vertical section of the T-shaped seat 521 and the second connecting seat 421. Arc-shaped grips are jointly hinged on the front and rear side walls of the vertical section of the T-shaped seat 521.

[0045] Pull out the positioning pin 553 to release the limit between the T-shaped seat 521 and the second connecting seat 421. Hold the arc-shaped grip and rotate the T-shaped seat 521 by ninety degrees. The T-shaped seat 521 drives the second rotating base 522 and the corresponding support rod 53 to rotate together. Insert the positioning pin 553 to lock the changed position of the T-shaped seat 521 and the second connecting seat 421. At this time, the hinge seat 551 forms a cross-shaped structure with the hinge seat 551. The support rods 53 on the first connecting component 51 and the second connecting component 52 support the sleeve 1 from four directions respectively, enhancing the stability of the structure.

[0046] During the rotation of the T-shaped seat 521, the spring rod 552 is stretched to adapt to the angular change of the rotation of the T-shaped seat 521. The hinge seat 551 is driven to rotate by the traction of the spring rod 552 to adapt to the position change of the spring rod 552. The spring rod 552 keeps the connection state between the T-shaped seat 521 and the hinge seat 551 all the time, and a triangular stable structure is formed among the spring rod 552, the T-shaped seat 521 and the hinge seat 551, enhancing the stability of the support rod 53.

[0047] The disc seat 541 is pressed downward, and the disc seat 541 drives the rack 1 542 to move downward. The spring 4 is stretched, and the serrated outer wall of the rack 1 542 pushes the serrated outer wall of the rack 2 544. The spring 5 between the rack 2 544 and the inner wall of the support rod 53 is stretched and contracted to adapt to the position change of the rack 2 544. The rack 2 544 limits the rack 1 542 to only move in one direction toward the bottom of the support rod 53. The bottom wall of the disc seat 541 is provided with a rubber pad, which increases the friction with the surface of the floor whose thickness needs to be tested and enhances the stability during the core drilling process. Before testing, multiple disc seats 541 are moved downward until the rubber pads of the disc seats 541 are completely in contact with the surface of the floor whose thickness needs to be tested, so as to quickly level the support position of the support rod 53 according to the horizontal position of the sleeve 1, thereby ensuring that the core drilling mechanism 3 is vertical to the sampling position of the floor, thereby ensuring that the core sample obtained after core drilling can accurately reflect the thickness of the floor.

[0048] The inverted L-shaped handle of the horizontal check member 6 is pushed to rotate around the slide rail of the side wall of the sleeve 1. If the bottom wall of the slider of the horizontal check member 6 is not blocked during the movement, it means that the sleeve 1, the core drill 34 and the floor are in a vertical state, and the core drilling operation can be carried out after the verification is completed. It should be noted that the existing level meter can also be used to verify whether the position of the core drill 34 is adjusted and aligned.

[0049] When drilling the core, the support rod 53 is used to support in multiple directions, and the stabilizing rod 321 and the spring rod 552 are used to maintain stability and balance. The output end of the motor 33 drives the core drill 34 to rotate, and the output end of the hydraulic cylinder 31 continues to push the support seat 322 downward to perform the core drilling operation. When the core drilling operation is completed, the core sample is taken out from the floor slab, and the total length of the core sample is accurately measured using a caliper or a steel ruler to obtain the thickness of the floor slab.

[0050] When the core drilling is completed, each mechanism is reset, and the release block 543 is pulled toward the outside of the support rod 53, the spring five is compressed, and the rack two 544 moves away from the rack one 542 to release the restriction on the rack one 542, and the spring four rebounds to drive the rack one 542 and the disc seat 541 to move upward and reset.

[0051] Pull out the positioning pin 553, rotate the T-shaped seat 521 to reset, shrink the spring rod 552 to reset, remove the latch connecting the inverted L-shaped plate 513 and the rotating seat 1 512, and the latch connecting the cross plate 523 and the T-shaped seat 521, the rotating seat 1 512 no longer maintains the vertical state formed with the connecting rod 511, and the rotating seat 2 522 no longer maintains the vertical state formed with the T-shaped seat 521, remove the support rod 53 detachably connected to the rotating seat 1 512 and the rotating seat 2 522, flip and fold the rotating seat 1 512 and the rotating seat 2 522 to save the space occupied by the equipment.

[0052] When the quick-release component I 41 and the quick-release component II 42 are in a connected state, the U-shaped gasket 423 is engaged with the outer wall of the round rod 412 to block the up and down movement of the second frustum 414, and the first frustum 413 is limited by the limiting member 422. When it is necessary to separate the quick-release component I 41 from the quick-release component II 42, remove the U-shaped gasket 423, push the sleeve 1 upward to move the first connecting seat 411, drive the round rod 412, the first frustum 413 and the second frustum 414 upward. The bottom wall of the second frustum 414 always abuts against the top wall of the first connecting seat 411, and the edge of the top wall of the second frustum 414 gradually pushes the two limiting members 422 away from each other, and the third spring is compressed until the edge of the second frustum 414 breaks through the highest point of the wedge block of the limiting member 422, and the side wall of the second frustum 414 is limited by the limiting member 422.

[0053] Pull the sleeve 1 downward to move the first connecting seat 411, drive the round rod 412 and the first frustum 413 downward. At this time, the second frustum 414 cannot move downward due to being limited by the two limiting members 422, so it slides relative to the outer wall of the round rod 412. When the bottom wall of the first frustum 413 slides downward to fit with the top wall of the second frustum 414, the first frustum 413 being pulled downward drives the second frustum 414 to move downward. By pushing and pulling once, the quick separation of the quick-release component I 41 and the quick-release component II 42 can be quickly realized, so as to facilitate the quick disassembly and assembly of the sleeve 1, split the equipment into two parts, and cooperate with the folding function for easy storage and transfer. Of course, the two limiting members 422 can also be directly pulled in the direction away from each other, so as to release the limitation of the limiting member 422 on the first frustum 413 and realize the separation of the quick-release component I 41 and the quick-release component II 42.

[0054] Refer to Figures 1 to 9 , the specific operation steps of this equipment are as follows:

[0055] First, clearly mark the drilling center position on the surface of the floor slab to be detected in thickness with chalk or other means, lift the assembled equipment and place it on the surface of the floor slab to be detected in thickness, and align the bottom of the positioning member 223 with the marked drilling center position for preliminary positioning.

[0056] Rotate the T-shaped seat 521 by ninety degrees. The T-shaped seat 521 drives the second rotating seat 522 and the corresponding support member 53 to rotate together. At this time, the hinge seat 551 forms a cross-shaped structure with the hinge seat 551.
