Description

Technical Field

[0001] This utility model relates to the technical field of concrete impact resistance testing, and in particular to an impact resistance testing device for road repair of impact-resistant and wear-resistant concrete. Background Technology

[0002] Impact testing equipment for road repair is a key device for evaluating the performance of concrete materials under dynamic loads and long-term wear conditions. Its core functions must cover impact energy testing, wear resistance assessment, and long-term durability simulation. Concrete impact testing typically involves dropping a heavy object freely or impacting the concrete with a certain acceleration, causing damage or fracture to the concrete block.

[0003] Utility model patent document with announcement number CN216410937U discloses a concrete impact resistance testing device, including an impact component, an impact assembly, an adjustment assembly, a box, a fixing assembly, and a storage box. The fixing assembly is located on the bottom wall of the box, the adjustment assembly is located on the fixing assembly and the inner side wall of the box, the storage box is located on the adjustment assembly, the impact assembly is located on the inner side wall of the box, the impact assembly is located at the upper end of the adjustment assembly, the impact component is located on the impact assembly, and the impact component is located at the upper end of the storage box.

[0004] Although the aforementioned concrete impact testing device patent document can adjust the height of the iron ball to complete impact tests at various heights, the iron ball will bounce and splash when it falls and comes into contact with the concrete block, which can easily cause injury to workers. Therefore, this utility model proposes an impact-resistant and wear-resistant concrete impact testing device for road repair that is different from the existing technology to solve the above-mentioned technical problems. Summary of the Invention

[0005] To address the aforementioned problem of iron balls rebounding and splashing upon contact with concrete blocks, potentially causing injury to workers, this invention provides an impact-resistant and wear-resistant concrete impact testing device for road repair.

[0006] This utility model provides an impact resistance testing device for impact-resistant and wear-resistant concrete used in road repair, employing the following technical solution: An impact-resistant and wear-resistant concrete impact testing device for road repair includes a horizontal plate, an impact-resistant and wear-resistant concrete block disposed on the upper surface of the horizontal plate, a hoisting unit installed on the upper surface of the horizontal plate, a placement frame installed at the bottom end of the hoisting unit, a through hole opened in the bottom wall of the placement frame, a steel ball control unit disposed in the inner cavity of the placement frame, a steel ball disposed on the steel ball control unit, an anti-splash inner tube fixed to the bottom wall of the placement frame, and an anti-splash outer tube movably sleeved on the outside of the anti-splash inner tube; The height of the placement frame can be adjusted by the hoisting unit, the movement and drop of the steel ball can be controlled by the steel ball control unit, and the anti-splash inner tube and anti-splash outer tube can prevent the steel ball from accidentally separating from the impact-resistant and wear-resistant concrete block during the drop.

[0007] By adopting the above technical solution, steel balls are placed on two sets of steel ball control units, and then impact-resistant and wear-resistant concrete blocks are placed on the upper surface of the horizontal plate. The steel ball control units are activated to make the steel balls automatically fall onto the upper surface of the impact-resistant and wear-resistant concrete blocks to generate impact force. At this time, the staff only needs to check whether the impact-resistant and wear-resistant concrete blocks are damaged or broken, thereby testing the impact resistance performance of the impact-resistant and wear-resistant concrete blocks.

[0008] Optionally, the hoisting unit includes a mounting frame, which is fixed to the outer edge of the upper surface of the horizontal plate. An electrically controlled winch is installed on the top wall of the mounting frame, and a steel wire rope that penetrates the top wall of the mounting frame is installed at the output end of the electrically controlled winch. The bottom end of the steel wire rope is fixed to the inner wall of the placement frame.

[0009] By adopting the above technical solution, starting the electric winch drives the wire rope to retract or unwind, thereby driving the placement frame and the anti-splash inner tube to move up and down synchronously, thus adjusting the height of the placement frame.

[0010] Optionally, the steel ball control unit includes a second cylinder, which is fixed to the bottom wall of the inner cavity of the placement frame. A pad is installed at the output end of the second cylinder, and the pad is in contact with the steel ball.

[0011] By adopting the above technical solution, the two sets of second cylinders are activated to retract, thereby driving the pad plate to move horizontally. During the movement of the pad plate, the steel ball will shake and separate from the pad plate. Then, under the action of the through hole, the steel ball will automatically fall into the anti-splash inner tube.

[0012] Optionally, multiple sets of first cylinders are installed on the upper surface of the horizontal plate, and clamping plates are installed at the ends of the output shafts of the multiple sets of first cylinders. The outer walls of the multiple sets of clamping plates are in contact with the outer walls of the impact-resistant and wear-resistant concrete block.

[0013] By adopting the above technical solution, multiple sets of first cylinders are activated to extend and retract, thereby driving the clamping plate to move horizontally, so that the clamping plate can engage with or separate from the impact-resistant and wear-resistant concrete block, which is convenient for use with impact-resistant and wear-resistant concrete blocks of different sizes.

[0014] Optionally, hollow slide rails are installed at the top of the inner walls on both sides of the mounting frame, and each set of hollow slide rails is provided with pulleys that are fixed to the outer wall of the placement frame.

[0015] By adopting the above technical solution, when the placement frame moves up and down, it can drive the pulley to rotate synchronously in the inner cavity of the hollow slide rail, thereby restricting the movement path of the placement frame.

[0016] Optionally, handles are welded to the outer walls on both sides of the anti-splash outer tube.

[0017] By adopting the above technical solution, the steel ball can be quickly removed by holding the handle and pushing the anti-splash outer tube upwards to move synchronously on the outer wall of the anti-splash inner tube, thereby separating the steel ball from the anti-splash outer tube.

[0018] In summary, this utility model has at least one of the following beneficial effects: This invention uses the retraction of the second cylinder to cause the steel ball to fall into the anti-splash inner tube. Under the action of the anti-splash inner tube and the anti-splash outer tube, the steel ball will not bounce and splash when it comes into contact with the impact-resistant and wear-resistant concrete block during the fall, which is safer and less likely to cause injury to workers.

[0021] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0022] Example 1: This example provides an impact-resistant and abrasion-resistant concrete impact testing device for road repair, such as... Figure 1 and Figure 2As shown, this invention solves the problem of iron balls rebounding and splashing when they come into contact with concrete blocks, which could easily cause injury to workers. It includes a horizontal plate 9, with an impact-resistant and wear-resistant concrete block 8 on the upper surface of the horizontal plate 9. A hoisting unit is installed on the upper surface of the horizontal plate 9. The hoisting unit includes a mounting frame 14. The lateral longitudinal section of the mounting frame 14 is set as an inverted U-shape. The mounting frame 14 is fixed to the outer edge of the upper surface of the horizontal plate 9. An electric winch 15 is installed on the top wall of the mounting frame 14. A steel wire rope 17 is installed at the output end of the electric winch 15, which passes through the top wall of the mounting frame 14. A placement frame 3 is installed at the bottom end of the steel wire rope 17. The upper surface of the placement frame 3 is set as an opening, and a through hole 11 is opened on the bottom wall of the placement frame 3.

[0023] Combination Figure 1 , Figure 2 and Figure 3 In an embodiment of this utility model, a steel ball control unit is provided in the inner cavity of the placement frame 3. The steel ball control unit includes a second cylinder 12, which is fixed on the bottom wall of the inner cavity of the placement frame 3. A pad 13 is installed at the output end of the second cylinder 12. The longitudinal section of the pad 13 is L-shaped. Steel balls 16 are provided on the two sets of pads 13. The diameter of the steel balls 16 is smaller than the diameter of the through hole 11. An anti-splash inner tube 4 is fixed on the bottom wall of the placement frame 3. The anti-splash inner tube 4 is located directly below the through hole 11. The inner diameter of the anti-splash inner tube 4 is larger than the cross-sectional size of the through hole 11. An anti-splash outer tube 10 is movably sleeved on the outside of the anti-splash inner tube 4. The bottom end of the anti-splash outer tube 10 is in contact with the upper surface of the impact-resistant and wear-resistant concrete block 8.

[0024] The steel ball 16 is placed between the two sets of pads 13. The two sets of second cylinders 12 are activated to retract, causing the steel ball 16 to automatically fall onto the upper surface of the impact-resistant and wear-resistant concrete block 8 under the conduction of the anti-splash inner tube 4 and the anti-splash outer tube 10, thereby testing the impact resistance of the impact-resistant and wear-resistant concrete block 8.

[0025] Combination Figure 1 and Figure 3 In this embodiment of the invention, multiple sets of first cylinders 6 are installed on the upper surface of the horizontal plate 9. Each set of first cylinders 6 has a clamping plate 7 installed at the end of its output shaft. The outer walls of the clamping plates 7 contact the outer walls of the impact-resistant and wear-resistant concrete block 8. Activating the extension and retraction of the multiple sets of first cylinders 6 can drive the clamping plates 7 to move horizontally, allowing the clamping plates 7 to engage with or disengage from the impact-resistant and wear-resistant concrete block 8, making it suitable for impact-resistant and wear-resistant concrete blocks 8 of different sizes.

[0026] Combination Figure 1 and Figure 2In this embodiment of the invention, hollow slide rails 1 are installed at the top of the inner walls on both sides of the mounting bracket 14. Each set of hollow slide rails 1 contains pulleys 2 fixed to the outer wall of the placement frame 3. Both the hollow slide rails 1 and the pulleys 2 are located on the outer side of the placement frame 3. When the placement frame 3 moves up and down, it drives the pulleys 2 to rotate synchronously within the cavity of the hollow slide rails 1, thereby restricting the movement path of the placement frame 3.

[0027] Combination Figure 1 and Figure 3 In this embodiment of the invention, handles 5 are welded to the outer walls of both sides of the anti-splash outer tube 10, and anti-slip sleeves are installed on the outside of the handles 5. After the steel ball 16 has fallen, the worker only needs to hold the handles 5 and push the anti-splash outer tube 10 upward to move synchronously on the outer wall of the anti-splash inner tube 4, so that the steel ball 16 can be separated from the anti-splash outer tube 10 and the steel ball 16 can be quickly removed.

[0028] Working principle: When using this impact-resistant and wear-resistant concrete impact testing device for road repair, a steel ball 16 is placed between two sets of pads 13, and then the impact-resistant and wear-resistant concrete block 8 is placed on the upper surface of the horizontal plate 9. The two sets of second cylinders 12 are activated to retract, which can drive the pads 13 to move horizontally. During the movement of the pads 13, the steel ball 16 will shake and separate from the pads 13. Then, under the action of the through hole 11, the steel ball 16 will automatically fall into the anti-splash inner tube 4. Under the conduction of the anti-splash inner tube 4 and the anti-splash outer tube 10, it falls onto the upper surface of the impact-resistant and wear-resistant concrete block 8 and generates an impact force. At this time, the staff only needs to check whether the impact-resistant and wear-resistant concrete block 8 is damaged or broken, thereby testing the impact resistance performance of the impact-resistant and wear-resistant concrete block 8.

[0029] The anti-splash inner tube 4 and anti-splash outer tube 10 prevent the steel ball 16 from bouncing and splashing when it comes into contact with the impact-resistant and wear-resistant concrete block 8 during its fall, thus enhancing safety. After the steel ball 16 has fallen, the staff only needs to hold the handle 5 and push the anti-splash outer tube 10 upwards to move synchronously on the outer wall of the anti-splash inner tube 4, thereby separating the steel ball 16 from the anti-splash outer tube 10 and quickly removing the steel ball 16.

[0030] After the impact-resistant and wear-resistant concrete block 8 is placed or removed, multiple sets of first cylinders 6 are activated to extend and retract, thereby driving the clamping plate 7 to move horizontally. This allows the clamping plate 7 to engage or disengage with the impact-resistant and wear-resistant concrete block 8, making it suitable for impact-resistant and wear-resistant concrete blocks 8 of different sizes. The electric winch 15 is activated to drive the wire rope 17 to retract or unwind, thereby driving the placement frame 3 and the anti-splash inner tube 4 to move up and down synchronously. This allows the height of the steel ball 16 to be adjusted, facilitating the testing of the impact resistance performance of the impact-resistant and wear-resistant concrete block 8 at different heights. When the placement frame 3 moves up and down, it can drive the pulley 2 to rotate synchronously in the inner cavity of the hollow slide rail 1, thereby limiting the movement path of the placement frame 3.
