Description

Technical Field

[0001] This utility model relates to the technical field of concrete testing machines, specifically to a concrete erosion resistance testing machine. Background Technology

[0002] The concrete erosion testing machine utilizes a high-speed centrifugal rotating impeller to test the wear resistance of various concrete surfaces against water flow impact. A steel ball grinding machine is one type of concrete erosion testing machine. Patent CN201721410082.2 discloses a concrete erosion testing machine with a frame on the mixing paddle comprising multiple rhombuses, ensuring sufficient movement and grinding of the grinding steel balls at different heights, thus improving the accuracy and precision of the test. However, the steel cylinder requires manual fixing to the base plate using fixing plates, and disassembly and replacement require releasing the fixing plates, making operation quite inconvenient. Therefore, we propose the concrete erosion testing machine. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a concrete erosion resistance testing machine.

[0004] The technical solution adopted by this utility model to solve its technical problem is a concrete erosion resistance testing machine, including a base. The top surface of the base is provided with a sliding groove, and there are multiple sets of sliding grooves. Adjustable sliding seats are slidably installed in the sliding grooves, and a frame located at the top of the base is assembled between two sets of sliding seats. A lead screw that is screwed and connected to the sliding seat is rotatably installed in the sliding groove, and a worm gear is sleeved and installed at one end of the lead screw located on the outside of the base. A plate frame located on the outer periphery of the worm gear is assembled on the outer wall surface of the base, and there are two sets of plate frames. A worm gear that meshes with the worm gear is rotatably installed in the plate frame, and a reducer that is driven and connected to the worm gear is assembled on the outer wall surface of the plate frame. A servo motor is assembled at the power input end of the reducer.

[0005] The top surface of the frame has a groove, and a support seat is engaged in the groove. A cylinder is engaged in the support seat, and a locking block is mounted on the outer peripheral surface of the cylinder. There are multiple sets of locking blocks. The frame has an integrally constructed protective tube shell, and there are multiple sets of tube shells. A hydraulic rod for adjustment is mounted in the tube shell, and the power output end of the hydraulic rod is equipped with a locking seat that engages with the locking block.

[0006] By adopting the above technical solution, when using the concrete erosion testing machine, and after the test is completed, the servo motor on the outside of the base can be operated. The operation of the servo motor facilitates the rotation of the worm gear in the plate frame under the operation of the reducer, so that the worm gear can mesh with the worm wheel and drive the worm wheel to rotate. Then the worm wheel can drive the lead screw in the slide groove inside the base to rotate, so that the lead screw and the slide block in the slide groove can be screwed together, causing the slide block to slide and move in the slide groove, thereby facilitating the movement of the frame, which in turn drives the cylinder to move, facilitating the subsequent processing of the internal components of the cylinder. At the same time, the automatic movement method is more convenient.

[0007] Once the cylinder is moved to the appropriate position by the frame, the hydraulic rod inside the shell of the frame can be activated. The operation of the hydraulic rod facilitates the pushing of the locking block through the locking seat, which in turn drives the cylinder to move up and down. This allows the cylinder to separate from the rubber seat in the groove on the surface of the frame, making it easier to replace the concrete inside the cylinder. The automatic opening and closing mechanism is also more convenient. At the same time, the locking block and the locking seat are easy to disassemble and assemble, making it easy to replace the cylinder and use it.

[0008] Specifically, both the outer wall surface of the card block and the outer wall surface of the card seat are provided with insertion holes, and a ring cover located around the insertion hole is screwed onto the outer wall surface of the card seat. A cross-shaped insertion rod that is inserted into and connected to the insertion hole is slidably installed inside the ring cover, and a spring for pushing the cross-shaped insertion rod to move is assembled between the ring cover and the card seat.

[0009] By adopting the above technical solution, when the card seat and the card block on the outer periphery of the cylinder are engaged with each other, the spring between the ring cover and the card seat can easily push the cross rod, so that the cross rod can move and easily be inserted into the insertion hole on the outer periphery of the card seat and the card block. This makes it easy to tighten the card seat and the card block when they are engaged with each other. At the same time, simply pull the cross rod on the outer periphery of the ring cover so that the cross rod can squeeze the spring on the inner periphery of the ring cover and easily separate from the insertion hole. This allows the engaged card block and the card seat to be separated from each other, making it easy to disassemble the cylinder. The disassembly and assembly are simple and convenient.

[0010] Specifically, the top surface of the base is equipped with a frame, and the top surface of the frame is equipped with an electric push rod for adjustment. There are multiple sets of electric push rods. The power output end of the electric push rod is equipped with a bucket lid that fits into the cylinder. The top surface of the bucket lid is equipped with a mixer for concrete erosion resistance testing.

[0011] By adopting the above technical solution, the agitator on the surface of the bucket lid can be conveniently operated to assist in the test of concrete erosion resistance. After the concrete erosion resistance test is completed, the electric push rod on the top of the frame can be operated. The operation of the electric push rod can easily move the bucket lid and separate the bucket lid from the cylinder, as well as separate the agitator from the cylinder, thereby allowing the frame to move.

[0012] Specifically, the top opening of the bucket lid is screwed onto a screw cap for sealing.

[0013] By adopting the above technical solution, the screw cap on the surface of the barrel lid is easy to install and remove, making it convenient to add auxiliary materials for concrete erosion resistance to the inside of the barrel.

[0014] Specifically, the outer wall surface of the tube shell is fitted with a shell cover for maintenance.

[0015] By adopting the above technical solution, the shell cover is easy to disassemble and assemble, facilitating the maintenance of the internal structure of the shell.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The technical solution of this application, through the design of a slide groove, lead screw, slide block, frame, groove, rubber seat, cylinder, reducer, plate frame, worm gear, and worm wheel, enables the servo motor on the outside of the base to operate when the concrete erosion testing machine is used and after the test is completed. The operation of the servo motor facilitates the rotation of the worm gear in the plate frame under the operation of the reducer, so that the worm gear can mesh with the worm wheel and drive the worm wheel to rotate. Subsequently, the worm wheel can drive the lead screw in the slide groove inside the base to rotate, so that the lead screw and the slide block in the slide groove can screw together and slide in the slide groove, thereby facilitating the movement of the frame, which in turn drives the cylinder to move, facilitating subsequent processing of the internal components of the cylinder. At the same time, the automatic movement method is more convenient.

[0018] 2. The technical solution of this application, through the design of the tube shell, hydraulic rod, and locking block, enables the hydraulic rod in the tube shell inside the frame to operate when the cylinder moves to the appropriate position with the frame. The operation of the hydraulic rod facilitates the pushing of the locking block through the locking seat, causing the locking block to drive the cylinder to move up and down, and separating the cylinder from the rubber seat in the groove on the surface of the frame. This facilitates the replacement of the concrete inside the cylinder, and the automatic opening and closing method is more convenient. At the same time, the locking block and the locking seat are easy to disassemble and assemble, making it easy to disassemble and replace the cylinder and use it. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figure 1-3 This utility model provides a technical solution: a concrete erosion resistance testing machine, including a base 1. A groove 2 is formed on the top surface of the base 1, and there are multiple sets of grooves 2. Adjustable sliding blocks 3 are slidably installed within the grooves 2, and a frame 4 located on the top of the base 1 is assembled between two sets of sliding blocks 3. A lead screw 5, screwed and connected to the sliding blocks 3, is rotatably installed within the grooves 2, and a worm gear 6 is sleeved on one end of the lead screw 5 located outside the base 1. A plate frame 7 located around the worm gear 6 is assembled on the outer wall surface of the base 1, and there are two sets of plate frames 7. A worm 8, meshing with the worm gear 6, is rotatably installed within the plate frame 7. Furthermore, the outer wall surface of the frame 7 is equipped with a reducer 9 that is connected to the worm gear 8 for transmission, and the power input end of the reducer 9 is equipped with a servo motor 10; the top surface of the frame 4 has a groove 13, and a rubber seat 14 for support is snapped into the groove 13. A cylinder 15 is snapped into the rubber seat 14, and a locking block 16 is installed on the outer peripheral surface of the cylinder 15. There are multiple sets of locking blocks 16. The frame 4 has an integrally constructed tube shell 11 for protection, and there are multiple sets of tube shells 11. A hydraulic rod 12 for adjustment is installed inside the tube shell 11, and the power output end of the hydraulic rod 12 is equipped with a locking seat 17 that engages with the locking block 16.

[0026] When the concrete erosion testing machine is used, and after the test is completed, the servo motor 10 on the outside of the base 1 can be operated. The operation of the servo motor 10 facilitates the rotation of the worm 8 in the plate frame 7 under the operation of the reducer 9, so that the worm 8 can mesh with the worm wheel 6 and drive the worm wheel 6 to rotate. Then the worm wheel 6 can drive the lead screw 5 in the slide groove 2 inside the base 1 to rotate, so that the lead screw 5 and the slide seat 3 in the slide groove 2 can be screwed together, so that the slide seat 3 can slide and move in the slide groove 2, thereby facilitating the movement of the frame 4, and the frame 4 can drive the cylinder 15 to move, which facilitates the subsequent processing of the components inside the cylinder 15. At the same time, the automatic movement method is more convenient.

[0027] When the cylinder 15 moves to the appropriate position with the frame 4, the hydraulic rod 12 in the inner shell 11 of the frame 4 can be operated. The operation of the hydraulic rod 12 can easily push the locking block 16 through the locking seat 17, so that the locking block 16 can drive the cylinder 15 to move up and down, and separate the cylinder 15 from the rubber seat 14 in the groove 13 on the surface of the frame 4. This makes it easier to replace the concrete inside the cylinder 15, and the automatic opening and closing method is more convenient. At the same time, the locking block 16 and the locking seat 17 are easy to disassemble and assemble, making it easy to disassemble and replace the cylinder 15 and use it.

[0028] like Figure 1 and Figure 3 As shown, both the outer surface of the card block 16 and the outer surface of the card seat 17 are provided with insertion holes 19, and an annular cover 18 located around the insertion hole 19 is screwed onto the outer surface of the card seat 17. A cross-shaped insertion rod 20 that is inserted into and connected to the insertion hole 19 is slidably installed inside the annular cover 18, and a spring 21 for pushing the cross-shaped insertion rod 20 to move is assembled between the annular cover 18 and the card seat 17.

[0029] In use, when the card holder 17 and the card block 16 on the outer periphery of the cylinder 15 are engaged with each other, the spring 21 between the ring cover 18 and the card holder 17 can easily push the cross rod 20, so that the cross rod 20 can move and easily be inserted into the insertion hole 19 on the outer periphery of the card holder 17 and the card block 16, which is convenient for fastening the card holder 17 and the card block 16 when they are engaged with each other. At the same time, simply pull the cross rod 20 on the outer periphery of the ring cover 18, so that the cross rod 20 can squeeze the spring 21 on the inner periphery of the ring cover 18 and easily separate from the insertion hole 19, thereby separating the engaged card block 16 and the card holder 17, which is convenient for disassembling the cylinder 15, and the disassembly and assembly are simple and convenient.

[0030] like Figure 1As shown, a frame 22 is mounted on the top surface of the base 1, and an electric push rod 23 for adjustment is mounted on the top surface of the frame 22. There are multiple sets of electric push rods 23. The power output end of the electric push rod 23 is equipped with a bucket lid 24 that fits with the cylinder 15. A mixer 25 for concrete erosion resistance testing is mounted on the top surface of the bucket lid 24.

[0031] During use, the agitator 25 on the surface of the bucket lid 24 facilitates the operation of the concrete erosion resistance test. After the concrete erosion resistance test is completed, the electric push rod 23 on the top of the frame 22 can be operated. The operation of the electric push rod 23 facilitates the movement of the bucket lid 24, and the bucket lid 24 and the cylinder 15 are separated from each other. At the same time, the agitator 25 and the cylinder 15 are separated from each other, thereby allowing the frame 4 to move.

[0032] like Figure 1 As shown, a screw cap 26 for sealing is screwed onto the open end of the top of the barrel lid 24.

[0033] When in use, the screw cap 26 on the surface of the barrel lid 24 is easy to install and remove, making it convenient to add auxiliary materials for concrete erosion resistance to the inside of the cylinder 15.

[0034] like Figure 1 As shown, the outer wall surface of the tube shell 11 is fitted with a shell cover 27 for maintenance.

[0035] During use, the cover 27 is easy to disassemble and assemble, facilitating the maintenance of the internal structure of the tube shell 11.

[0036] The working principle and usage process of this utility model are as follows: First, install the corresponding structural components in suitable positions. When using the concrete erosion testing machine, and after the test is completed, the electric push rod 23 on the top of the frame 22 can operate. The operation of the electric push rod 23 facilitates the movement of the bucket lid 24, separating the bucket lid 24 from the cylinder 15 and simultaneously separating the agitator 25 from the cylinder 15. Then, the servo motor 10 on the outside of the base 1 can operate. The operation of the servo motor 10 facilitates the rotation of the worm 8 in the plate frame 7 under the operation of the reducer 9, allowing the worm 8 to mesh with the worm wheel 6 and rotate the worm wheel 6. Subsequently, the worm wheel 6 facilitates the rotation of the lead screw 5 in the sliding groove 2 inside the base 1, causing the lead screw 5 to screw into the sliding seat 3 in the sliding groove 2, allowing the sliding seat 3 to slide and displace in the sliding groove 2. This facilitates the movement of the frame 4, which in turn moves the cylinder 15, facilitating subsequent cylinder... The internal components of the body 15 are processed, and the automatic movement method is more convenient. After the body 15 moves to the appropriate position with the frame 4, the hydraulic rod 12 in the inner shell 11 of the frame 4 can be operated. The operation of the hydraulic rod 12 can push the locking block 16 through the locking seat 17, so that the locking block 16 can drive the body 15 to move up and down, and separate the body 15 from the rubber seat 14 in the groove 13 on the surface of the frame 4. This makes it easier to replace the concrete inside the body 15. The automatic opening and closing method is more convenient. When it is necessary to disassemble and replace the body 15, simply pull the cross-shaped insert 20 on the outer periphery of the locking seat 17, so that the cross-shaped insert 20 can squeeze the spring 21 inside the ring cover 18 and separate the cross-shaped insert 20 from the insertion hole 19. Then the locking seat 17 and the locking block 16 can be separated, which makes it easier to disassemble and replace the body 15, thus making the concrete erosion tester more convenient to use.
