Description

Technical Field

[0001] This utility model belongs to the field of concrete hardness testing technology, and specifically relates to a device for testing the hardness of concrete used in bridge construction. Background Technology

[0002] Concrete is a general term for engineering composite materials in which aggregates are bound together by cementing materials. The term concrete usually refers to concrete that uses cement as cementing material and sand and stone as aggregates. In the construction of bridges, concrete is used to pave the bridge surface. Before the bridge is put into use, the hardness of the concrete on the bridge surface needs to be tested, which leads to the use of a hardness testing device for bridge construction concrete to facilitate later acceptance.

[0003] Chinese Patent No. CN217845940U discloses a device for testing the hardness of concrete in bridge construction, belonging to the field of bridge construction technology. It addresses the problem that when testing the hardness of bridge concrete, the irregular size and shape of the collected concrete test blocks can easily lead to insufficient clamping and fixation, requiring testers to move the concrete test blocks up and down, resulting in high labor intensity and low work efficiency. The device includes a workbench with a fixing mechanism located on one side of the fixing plate b at the top of the workbench.

[0004] However, this device still has some shortcomings. When testing the hardness of concrete, it is done by applying pressure downwards. If the concrete's resistance is lower than the applied pressure during the testing process, it is easy for it to crack. The cracked debris is extremely difficult to clean up and can easily splash onto the testing personnel, thus reducing the safety of the hardness test. Utility Model Content

[0010] As a preferred technical solution, a locking block is fixedly connected to the other side of the support plate, and a locking groove matching the locking block is opened on the inner wall of the opening, with the position of the locking groove corresponding to the position of the locking block.

[0011] As a preferred technical solution, the top of the bracket is provided with a third sliding groove that matches the collection box. The collection box is slidably connected to the top of the bracket through the third sliding groove. A handle is fixedly connected to one side of the collection box. The handle has an arc-shaped corner. A fixing plate is fixedly connected to one side of the collection box. A slot is provided at the top of the fixing plate.

[0014] In summary, the present invention has the following main advantages:

[0015] First, during use, place the concrete on top of the support plate, then turn the screw. The rotating shaft will allow the end of the screw to rotate in place, and the second clamping plate will move along the second sliding groove. The concrete can then be clamped by the first and second clamping plates, which also helps to limit the size of concrete. After the limit is completed, start the electric cylinder to push the detection plate to move. Use the detection cone to apply pressure to the concrete for testing. During the movement, the protective cover can cover the top of the transparent cover. If the concrete collapses in the middle, the protective cover and the transparent cover can effectively protect the surrounding area of ​​the concrete. While improving the safety of hardness testing, it also effectively avoids the problem of splashed concrete being difficult to clean.

[0016] Secondly, the presence of the locking block effectively limits the positioning of the support plate, thus improving the stability of the support plate's fixed position. When the tested concrete needs to be removed later, the user can pull the support plate by the handle and use the first sliding groove to pull the support plate out of the slot, thereby exposing the opening. The tested concrete can then fall directly into the collection box through the opening. After that, the locking block can be inserted into the slot to test the hardness of the next concrete. This not only improves the efficiency of concrete feeding but also facilitates the unified collection and transportation of concrete later. Attached Figure Description

A round hole 10 is opened at the top end of the protective cover 9, and the telescopic shaft of the electric cylinder 6 is located inside the round hole 10. The protective cover 9 covers the top end of the transparent cover 19. In use, concrete is placed on the top of the support plate 23, which can effectively support the concrete point. Then, the screw 21 is turned, and the rotating shaft 18 can rotate the end of the screw 21. The first clamp 12 rotates, and the second clamp 15 moves along the second slide 17. Under the mutual clamping of the first clamp 12 and the second clamp 15, concrete of different sizes can be clamped and limited.

Due to the presence of the locking block 25, the locking block 25 can be engaged. Effectively limiting the support plate 23 can effectively improve the stability of the support plate 23's fixed position. When the tested concrete needs to be removed later, the user can pull the support plate 23 through the handle 24 and use the first sliding groove 14 to pull the support plate 23 out of the strip opening 22, thereby exposing the through opening 11. The tested concrete can fall directly into the collection box 29 through the through opening 11. Then, the card block 25 can be inserted into the card slot 26 to test the hardness of the next concrete, which can effectively improve the efficiency of concrete hardness testing.

[0026] refer to Figure 5 The top of the bracket 28 has a third groove 30 that matches the collection box 29. The collection box 29 is slidably connected to the top of the bracket 28 via the third groove 30. A handle 31 is fixedly connected to one side of the collection box 29. The handle 31 has rounded corners. A fixing plate 32 is fixedly connected to one side of the collection box 29. The top of the fixing plate 32 has a slot 33. The slots 33 all pass through the top of the fixing plate 32 and the bracket 28. A plug 34 is inserted into the inner side of the slot 33. The bottom end of the plug 34 passes through... The slot 33 is inserted into the bracket 28. The top of the insert 34 is fixedly connected to the protrusion 35. The protrusion 35 has an arc-shaped corner. Due to the opening of the third sliding groove 30, the collection box 29 can slide easily, so that the collection box 29 can be removed later to transfer the collected concrete. In order to prevent the collection box 29 from shifting during the collection of concrete, the insert 34 is inserted into the slot 33 to effectively limit the collection box 29. When the collection box 29 needs to be removed, the insert 34 can be pulled out through the protrusion 35.

[0027] refer to Figure 1 A power supply module 36 is installed at the top of the support platform 1, and a control module 37 is installed at the top of the support platform 1. The power supply module 36 is electrically connected to the control module 37 and the electric cylinder 6. The control module 37 is electrically connected to the electric cylinder 6. Due to the presence of the power supply module 36, the electrical equipment on the device can be effectively powered. The control module 37 can effectively control the electrical equipment on the device. It is more convenient and faster to operate the device through the control module 37.

[0028] refer to Figure 3 Rubber pads 13 are fixedly connected to one side of the first clamping plate 12 and the other side of the second clamping plate 15.

A telescopic rod 16 is fixedly connected to one side of the second clamping plate 15. One side of the telescopic rod 16 is fixedly connected to the inner wall of the opening 11. Due to the presence of the rubber pads 13, which are made of rubber, they have good anti-slip and rubber shock absorption capabilities. While improving the stability of the concrete clamping point, they can also effectively prevent the concrete clamping point from being bumped. The telescopic rod 16 includes a movable rod and a sleeve rod. The movable rod is sleeved inside the sleeve rod. Due to the presence of the telescopic rod 16, it can provide secondary support and limit on one side of the second clamping plate 15 without hindering the adjustment of the position of the second clamping plate 15, thereby effectively improving the stability of the adjustment of the position of the second clamping plate 15.

[0029] Operating principle and advantages: In use, concrete is placed on top of the support plate 23, which effectively supports the concrete. Then, the screw 21 is turned, and the shaft 18 rotates the end of the screw 21 in place. The second clamping plate 15 moves along the second sliding groove 17. Under the mutual clamping of the first clamping plate 12 and the second clamping plate 15, concrete of different sizes can be clamped and limited. After limiting, the electric cylinder 6 is activated to move the detection plate 7. The detection cone 8 applies pressure to the concrete for testing. During movement, the protective cover 9 can cover the top of the transparent cover 19 through the flow-through of the round hole 10. If... In the event of concrete spalling, the protective cover 9 and transparent cover 19 can effectively protect the surrounding area of ​​the concrete, improving the safety of hardness testing and effectively preventing the problem of difficult-to-clean splattered concrete. Due to the presence of bolts 5, screwing them in effectively fixes the top plate 3, preventing displacement. When the top plate 3 needs to be removed, simply unscrew the bolts 5 from their holes. This also facilitates future maintenance of the structure on the top plate 3. Due to the presence of the locking block 25, its insertion effectively limits the position of the support plate 23, improving the stability of the fixed position of the support plate 23. When the tested concrete needs to be removed, the user can pull the support plate 23 using the handle 24, and use the first sliding groove 14 to pull the support plate 23 outward from the slot 22, thus exposing the opening 11. The tested concrete can then fall directly into the collection box 29 through the opening 11. The locking block 25 can then be inserted into the locking groove 26 to perform hardness testing on the next concrete. This effectively improves the efficiency of concrete hardness testing. The third sliding groove 30 facilitates the sliding of the collection box 29, allowing for easy removal and transfer of the collected concrete later. To prevent displacement of the collection box 29 during concrete collection... Inserting the insert 34 into the slot 33 effectively limits the collection box 29. When the collection box 29 needs to be removed, the insert 34 can be pulled out through the protrusion 35. Due to the presence of the rubber pad 13, which is made of rubber and has good anti-slip and rubber shock absorption capabilities, it can improve the stability of the concrete clamping point and effectively prevent the concrete clamping point from being bumped. Due to the presence of the telescopic rod 16, it can provide secondary support and limit one side of the second clamping plate 15 without hindering the adjustment of the position of the second clamping plate 15, thereby effectively improving the stability of the adjustment of the position of the second clamping plate 15.
