Description

Technical Field

[0001] This utility model relates to the field of concrete performance testing technology, and in particular to a device for testing the abrasion resistance of polymer concrete. Background Technology

[0002] Polymer concrete, as a new type of building material, has been widely used in construction engineering, road and bridge projects, and other fields due to its advantages such as high strength, good durability, and corrosion resistance. However, in actual use, the wear resistance of polymer concrete has become a key factor affecting its service life.

[0003] one.

[0004] Existing concrete abrasion resistance testing devices are mainly designed for ordinary concrete. For special materials like polymer concrete, existing testing devices cannot perform tests under different pressure and abrasion conditions, which reduces the accuracy and reliability of the test results and cannot meet the needs of polymer concrete research and development and quality control. Therefore, a polymer concrete abrasion resistance testing device is proposed to address the above problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A device for testing the abrasion resistance of polymer concrete includes a workbench, a collection mechanism located at the bottom of the workbench, and an abrasion resistance testing mechanism installed above the workbench. The abrasion resistance testing mechanism includes limiting frames fixed to the top of the left and right ends of the workbench. The limiting frames contain positioning rods. The inner walls of the through holes at both ends of the lifting plate are slidably connected to the sides of the positioning rods. The sides of the positioning rods are fitted with collars, the top of which are fitted to the bottom sides of both ends of the lifting plate. A fixed seat is installed at the top of the middle end of the lifting plate. A drive motor is installed inside the fixed seat. The output end of the drive motor is connected to the top of the rotating rod via a coupling. A detachable grinding head is installed at the bottom of the rotating rod. A pressure detection plate is installed at the top of the fixed seat. The top of the pressure detection plate is vertically connected to the bottom of the loading rod. A weight is sleeved on the outside of the loading rod.

[0007] Preferably, the weights have a ring-shaped cross-section when viewed from above, and the number of weights is multiple, allowing for disassembly.

[0008] Preferably, an adjusting bolt is installed inside the outer wall of the collar.

[0009] Preferably, the worktable has internal track grooves at both ends, with threaded rods installed inside the track grooves. One end of the threaded rod is fixedly connected to the manual turntable, and the threaded hole inside the slider at the bottom of the clamp plate is connected to the outside of the threaded rod by a thread.

[0010] Preferably, the collection mechanism includes collection pipes located at the bottom of the front and rear ends of the workbench. One end of the collection pipe is connected to the interior of the front and rear of the ventilation box. An exhaust pipe is provided in the middle of the ventilation box, and an exhaust fan is installed inside the exhaust pipe. Filter screens are provided on both sides of the top of the exhaust pipe. The filter screens are located above the connection between the collection pipe and the ventilation box. Detachable collection frames are installed at both ends of the bottom of the ventilation box.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the grinding head grinds the surface of the test sample during rotation. Since there are weights on the loading rod, the gravity of the weights is transmitted to the grinding head through the pressure detection plate, so that the grinding head acts on the surface of the test sample with a certain pressure, simulating the actual wear conditions, which can meet the needs of polymer concrete research and development and quality control.

[0012] During the grinding process, the collection pipes at the bottom of the front and rear ends of the workbench are drawn into the collection pipes by the negative pressure inside the air exchange box. The debris and other impurities generated during grinding are then drawn into the air exchange box through the collection pipes. The filter screens on both sides of the top of the air outlet are located above the connection between the collection pipe and the air exchange box, which can prevent impurities from being discharged through the air outlet. The impurities entering the air exchange box will fall into the collection frame. The collection frame can be disassembled when it is full, which improves the ease of use of the device.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Please see Figure 1-3 This utility model provides an embodiment of a polymer concrete abrasion resistance testing device, comprising a workbench 1, a collection mechanism 4 disposed at the bottom of the workbench 1, and an abrasion resistance testing mechanism mounted above the workbench 1. The abrasion resistance testing mechanism includes a limiting frame 21 fixed to the top of the left and right ends of the workbench 1. A positioning rod 22 is installed inside the limiting frame 21. The inner sidewall of the through holes at both ends of the lifting plate 24 is slidably connected to the side of the positioning rod 22. A collar 23 is installed on the side of the positioning rod 22. The top side of the collar 23 is fitted and connected to the bottom side of both ends of the lifting plate 24. A fixed seat 25 is installed at the top of the middle end of the lifting plate 24. A drive motor 27 is installed inside the fixed seat 25. The output end of the drive motor 27 is connected to the top of the rotating rod 26 through a coupling. A detachable grinding head 261 is installed at the bottom of the rotating rod 26. A pressure detection plate 31 is installed at the top of the fixed seat 25. The top of the pressure detection plate 31 is vertically connected to the bottom of the loading rod 32. A weight 33 is sleeved on the outside of the loading rod 32.

[0021] The weight 33 has a ring-shaped cross-section when viewed from above, and there are multiple weights 33, which can be disassembled.

[0022] The inner side wall of the collar 23 is equipped with an adjusting bolt, which can adjust the friction between the collar 23 and the positioning rod 22. Before the weight 33 is added to the lifting plate 24, the lifting plate 24 and the collar 23 are in a balanced state. When the weight 33 is added, the lifting plate 24 and the collar 23 will descend together, which makes it easier to control the magnitude of the force on the surface of the test sample.

[0023] The workbench 1 has a track groove 11 inside at both ends. The track groove 11 is equipped with a threaded rod 12. One end of the threaded rod 12 is fixedly connected to the manual turntable 13. The threaded hole inside the slider at the bottom of the clamping plate 14 is connected to the outside of the threaded rod 12 by a thread.

[0024] The collection mechanism 4 includes a collection pipe 41 located at the bottom of the front and rear ends of the workbench 1. One end of the collection pipe 41 is connected to the interior of the ventilation box 42. The ventilation box 42 is provided with an exhaust pipe 43 in the middle. An exhaust fan 44 is installed inside the exhaust pipe 43. Filter screens 46 are provided on both sides of the top of the exhaust pipe 43. The filter screens 46 are located above the connection between the collection pipe 41 and the ventilation box 42. The bottom ends of the ventilation box 42 are equipped with detachable collection frames 45.

[0025] During the rotation of the grinding head 261, the surface of the test sample is ground. Since the loading rod 32 is fitted with a weight 33, the gravity of the weight 33 is transmitted to the grinding head 261 through the pressure detection plate 31, so that the grinding head 261 acts on the surface of the test sample with a certain pressure, simulating the actual wear condition.

[0026] During the polishing process, the collection pipes 41 at the bottom of both ends of the workbench 1, under the negative pressure inside the ventilation box 42, draw in the polishing debris and other impurities generated during polishing. These debris then enters the ventilation box 42 through the collection pipes 41. The filters 46 on both sides of the top of the exhaust pipe 43, located above the connection between the collection pipe 41 and the ventilation box 42, prevent impurities from being discharged through the exhaust pipe 43. Impurities entering the ventilation box 42 fall into the collection frame 45, which can be disassembled when full.

[0027] The device embodiments described above are merely illustrative. The units described as separate components may or may not be physically separate. The components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units. Some or all of the modules can be selected to achieve the purpose of this embodiment according to actual needs. Those skilled in the art can understand and implement this without any creative effort.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
