Description

Technical Field

[0001] This utility model relates to the field of engineering quality testing technology, specifically a floor slab thickness gauge for engineering quality testing. Background Technology

[0002] Construction project quality testing refers to the activities of testing and determining the quality characteristics of materials, components, equipment, and the physical quality and functionality of construction projects in accordance with relevant national laws, regulations, mandatory engineering construction standards, and design documents.

[0003] Currently, when testing the thickness of a floor slab, operators need to drill a hole from top to bottom in the slab. An operator on the lower floor slab holds up a measuring ruler and inserts it into the hole. Then, an operator on the floor slab to be tested assists in placing the measuring ruler and observes and records the values. This is a waste of manpower. Due to the large distance between the upper and lower floor slabs and the diverse indoor environments, it is sometimes inconvenient for multiple operators to work together, resulting in a slow testing speed.

Detailed Implementation

[0021] 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.

[0022] See Figures 1-5 In this embodiment of the present invention, a floor slab thickness gauge for engineering quality inspection includes a rotating rod 1. A first telescopic rod 4 is slidably connected to the bottom of the rotating rod 1. A telescopic connecting cylinder 7 is fixedly connected to the bottom of the rotating rod 1 through the first telescopic rod 4. A first rotating mounting seat 9 is fixedly connected to the top outer wall of the rotating rod 1. A rotating mounting cylinder 10 is rotatably connected inside the first rotating mounting seat 9. A connecting block 11 is fixedly connected to the outer wall of the rotating mounting cylinder 10. A fixed handle 12 is fixedly connected to the connecting block 11. The outer wall of the rotating rod 1... A fixed connection seat 13 is fixedly connected, and a second telescopic rod 14 is slidably connected inside the fixed connection seat 13. A rotating handle 15 is fixedly connected to one end of the second telescopic rod 14, and a stop block 17 is fixedly connected to the other end of the second telescopic rod 14. A spring 18 is provided between the stop block 17 and the fixed connection seat 13 and is sleeved on the outer wall of the second telescopic rod 14. A slot 16 is located in the end of the second telescopic rod 14 near the fixed handle 12. An insertion rod 19 is fixedly connected to the bottom of the fixed handle 12, and the insertion rod 19 cooperates with the slot 16.

[0023] A second rotating mounting base 20 is fixedly connected to the top of the rotating rod 1. A rotating frame 21 is rotatably connected inside the second rotating mounting base 20. A threaded cylinder 22 is fixedly connected inside the rotating frame 21. A screw 23 is threadedly connected inside the threaded cylinder 22. The screw 23 is fixedly connected to the first telescopic rod 4 through a connecting rod 8. A fixing frame 24 is fixedly connected to the outer wall of the rotating mounting cylinder 10. A rotating shaft 25 is rotatably connected inside the fixing frame 24. A second bevel gear 27 is fixedly connected to one end of the rotating shaft 25. A first bevel gear 26 is fixedly connected to the outer wall of the rotating frame 21. The first bevel gear 26 and the second bevel gear 27 mesh with each other. A crank handle 28 is fixedly connected to the other end of the rotating shaft 25. A clamping assembly is installed between the rotating rod 1 and the telescopic connecting cylinder 7. A scale 29 assembly is installed between the screw 23 and the rotating mounting cylinder 10.

[0024] This invention first raises the stop 17 via the spring 18, which in turn raises the second telescopic rod 14, allowing the insertion rod 19 to interlock with the slot 16. The interlocking of the insertion rod 19 and slot 16 then axially limits the movement between the fixed grip 12 and the rotating grip 15. At this point, the operator can grip the fixed grip 12 and crank the handle 28. The handle 28 rotates the rotating shaft 25, which in turn rotates the second bevel gear 27. The second bevel gear 27 interacts with the first bevel gear 26... The meshing of the first bevel gear 26 drives the first bevel gear 26 to rotate, which in turn drives the rotating frame 21 to rotate. The rotating frame 21 drives the threaded cylinder 22 to rotate. The threaded cylinder 22 is connected to the screw 23 by a thread, which converts the rotational motion of the threaded cylinder 22 into the linear motion of the screw 23. The screw 23 drives the first telescopic rod 4 to extend and retract within the rotating rod 1 through the connecting rod 8. The first telescopic rod 4 drives the telescopic connecting cylinder 7 to extend and retract, thereby adjusting the relative distance between the telescopic connecting cylinder 7 and the rotating rod 1, thus opening the clamping assembly.

[0025] Then, pull the rotating handle 15. The rotating handle 15 drives the second telescopic rod 14 to press down and compress the spring 18, thereby pulling the insertion rod 19 out of the slot 16. At this time, there is no longer axial limitation between the fixed handle 12 and the rotating handle 15. The operator can then hold the fixed handle 12 and the rotating handle 15 at the same time and rotate the rotating handle 15 around the rotating rod 1. This will drive the rotating rod 1 to rotate, thereby rotating the clamping assembly to face outwards from the floor and placing the floor slab between the gaps of the clamping assembly. Then, rotate the rotating handle 15 again to rotate the gaps of the clamping assembly to the upper and lower sides of the floor slab. Then, pull the rotating handle 15 again to insert the insertion rod 19 back into the slot 16. Then, shake the handle 28 again to close the clamping assembly, thereby clamping the two sides of the clamping assembly to the upper and lower surfaces of the floor slab. At this time, the relative extension distance between the rotating rod 1 and the screw 23 can be accurately measured through the scale 29 assembly, thereby achieving accurate measurement of the thickness of the floor slab.

[0026] In one instance of this embodiment, please refer to Figures 1-5 The inner wall of the rotating rod 1 is provided with a limiting groove 5, and the outer wall of the first telescopic rod 4 is fixedly connected with a limiting block 6. The limiting block 6 is slidably connected to the limiting groove 5. This utility model limits the axial movement between the first telescopic rod 4 and the rotating rod 1 through the mutual cooperation of the limiting groove 5 and the limiting block 6.

[0027] In one instance of this embodiment, please refer to Figures 1-5 The clamping assembly includes an extension arm 2 fixedly connected to the outer wall of the rotating rod 1 and the telescopic connecting cylinder 7. A clamp 3 is fixedly connected to the extension arm 2. The clamping assembly drives the two sets of extension arms 2 to retract relative to each other through the relative extension and retraction between the rotating rod 1 and the telescopic connecting cylinder 7. Then, the two sets of clamps 3 bring the upper and lower surfaces of the floor slab closer together, and the two sets of clamps 3 limit the movement between the rotating rod 1 and the telescopic connecting cylinder 7.

[0028] In one instance of this embodiment, please refer to Figures 1-5 The scale 29 assembly includes a scale 29 fixedly connected to the screw 23. A pointer groove 30 is provided on one side of the connecting block 11. The pointer groove 30 and the scale 29 cooperate with each other. When the screw 23 extends or retracts, it drives the scale 29 to extend or retract synchronously. The scale 29 and the pointer groove 30 slide relative to each other. Thus, through the cooperation of the pointer groove 30 and the scale 29, the scale of the scale 29 in the pointer groove 30 can be observed. Furthermore, the amount of extension or retraction of the screw 23 can be observed by the change in the scale before and after the extension or retraction of the screw 23.
