Description
Technical Field
[0001] This utility model relates to the field of road material testing technology, specifically a test device for the resistance of road materials to water erosion. Background Technology
[0002] Road surface refers to a layered structure paved with various road construction materials on the roadbed that directly bears vehicle loads. A good quality road surface should have sufficient strength and good stability, and its surface should meet the requirements of being smooth, dense, and skid-resistant.
[0003] Road surface materials require water erosion resistance testing during production. Existing testing devices for road surface materials often only use horizontal flowing water to wash the test blocks, failing to simulate the impact of slopes on road surface materials in actual engineering projects. This results in test results that significantly differ from actual service environments. Therefore, this invention provides a water erosion resistance testing device suitable for road surface materials to solve the aforementioned problems. Utility Model Content

[0007] A measuring component is provided on the test chamber with a corresponding connecting frame. The measuring component is used to record the weight of the test block.
[0008] An adjustment component is provided in the water channel corresponding to the inclined plate. The adjustment component is used to adjust the angle of the inclined plate, thereby simulating the impact of water flow at different slopes.

[0012] As a further embodiment of this utility model, a support plate is provided on the right side of the first threaded rod. The support plate is fixedly connected to the inner wall of the water tank, and a weighing device is provided at the upper end of the support plate. The test block can be easily pushed from the support plate to the weighing device by the push plate to be weighed, thereby recording the weight of the test block.
[0013] As a further embodiment of this utility model, the adjusting component includes a stop plate, the lower end of the inclined plate is attached to the stop plate, and positioning blocks are provided at both the front and rear ends of the stop plate. The positioning blocks are slidably connected to the inner wall of the water trough, and the inner wall of the water trough is provided with positioning grooves corresponding to the positioning blocks.

[0025] Example
[0026] like Figure 1 and Figure 2 As shown in the embodiment of this utility model, a water erosion resistance testing device suitable for road surface materials includes a test chamber 1, an inclined plate 7, and a measuring component 12. The test chamber 1 has symmetrically arranged water channels 101 at its upper end. A porous partition 8 is provided inside the water channel 101, and the inclined plate 7 is movably connected inside the rear side of the water channel 101. A support plate 11 is snapped onto the porous partition 8. A connecting frame 1101 is provided at the upper end of the support plate 11, and a test block 10 is provided at the upper end of the support plate 11. A stop bar 9 is attached to the right end of the test chamber 1. The front and rear ends of the stop bar 9 are fixedly connected to the inner wall of the water trough 101. A drain pipe 5 is provided on the right end of the test chamber 1 corresponding to the water trough 101. The other end of the drain pipe 5 is connected to the water inlet tank 2. A water outlet tank 3 is attached to the upper end of the test chamber 1. A water outlet pipe 6 is provided on the right end of the water outlet tank 3 corresponding to the water trough 101. Solenoid valves are provided on both the drain pipe 5 and the water outlet pipe 6. A water pump 4 is provided in the water inlet tank 2. A conveying pipe 401 is provided on the upper end of the water pump 4. The other end of the conveying pipe 401 is connected to the water outlet tank 3.
[0027] Measurement component 12: The test chamber 1 is provided with a measurement component 12 corresponding to the connecting frame 1101. The measurement component 12 is used to record the weight of the test block 10.
[0028] Adjustment component 13: The water channel 101 is provided with an adjustment component 13 corresponding to the inclined plate 7. The adjustment component 13 is used to adjust the angle of the inclined plate 7, thereby simulating the impact of water flow at different slopes.
[0029] Specifically, the test block 10 is placed on the support plate 11, and water in the water tank 3 is discharged through the water outlet pipe 6. The discharged water enters the water flow channel 101. The test block 10 in the front water flow channel 101 is horizontally washed by the flowing water, and the water in the rear water flow channel 101 is impacted by the inclined plate 7 structure to form a ramp water flow, thereby realizing the water erosion resistance test of the test block 10 under different scenarios. The combination of the inlet tank 2, outlet tank 3, water pump 4, delivery pipe 401, drain pipe 5 and outlet pipe 6 facilitates the recycling of water resources. When it is necessary to measure the weight of the test block 10, the weight of the test block 10 can be easily recorded by the set measuring component 12. When the test block 10 needs to be impacted by water flow at different slopes, the angle of the inclined plate 7 can be easily adjusted by the set adjustment component 13 to realize the impact of water flow at different slopes on the test block 10.
[0030] like Figure 2 and Figure 3 As shown, the measuring component 12 includes a first threaded rod 1201, and the first threaded rod 1201 is symmetrically threaded on the connecting frame 1101. A first limiting block 1202 is provided at the lower end of the first threaded rod 1201, and a first bearing 1203 is provided on the first threaded rod 1201. A fixing frame 1204 is provided on the outer wall of the first bearing 1203 and is fixedly connected to the test chamber 1.
[0031] Specifically, rotating the first threaded rod 1201 facilitates the upward movement of the connecting frame 1101, the support plate 11, and the test block 10, thereby making it easier to adjust the height of the test block 10.
[0032] The first threaded rod 1201 has a first gear 1205 at its upper end, and a second gear 1206 meshes between the two first gears 1205. The second gear 1206 has a rotating shaft 1207 at its upper end, and a first motor 1208 is provided at its upper end. The first motor 1208 has a mounting bracket 1209 that is fixedly connected to the fixing bracket 1204 at its upper end.
[0033] Specifically, by starting the first motor 1208, the rotating shaft 1207 and the second gear 1206 are driven to rotate, and the second gear 1206 in turn drives the first gear 1205 and the first threaded rod 1201 to rotate.
[0034] The first threaded rod 1201 has a push plate 1210 on the left side, an electric telescopic rod 1211 on the left end of the push plate 1210, a support frame 1212 on the left end of the electric telescopic rod 1211, and the support frame 1212 is fixedly connected to the test chamber 1.
[0035] Specifically, when the support plate 11 moves to be flush with the support plate 1213, the electric telescopic rod 1211 is activated to facilitate the movement of the push plate 1210, which in turn pushes the test block 10 to move.
[0036] The first threaded rod 1201 has a support plate 1213 on its right side. The support plate 1213 is fixedly connected to the inner wall of the water trough 101, and a weighing device 1214 is provided at the upper end of the support plate 1213.
[0037] Specifically, the pusher plate 1210 facilitates the pushing of the test block 10 from the support plate 11 to the weigher 1214 for weighing, thereby recording the weight of the test block 10.
[0038] like Figure 2 and Figure 4 As shown, the adjustment component 13 includes a backing plate 1301, the lower end of the inclined plate 7 is attached to the backing plate 1301, and the front and rear ends of the backing plate 1301 are provided with positioning blocks 1302. The positioning blocks 1302 are slidably connected to the inner wall of the water channel 101, and the inner wall of the water channel 101 is provided with positioning grooves 1303 corresponding to the positioning blocks 1302.
[0039] Specifically, the abutment plate 1301 provides support for the inclined plate 7, and the positioning block 1302 and positioning groove 1303 work together to limit the position of the abutment plate 1301 and ensure that the abutment plate 1301 slides along the positioning groove 1303.
[0040] The abutment plate 1301 is threadedly connected to a second threaded rod 1304. The right end of the second threaded rod 1304 is provided with a second limiting block 1305, and the left end of the second threaded rod 1304 is provided with a second motor 1306. The left end of the second motor 1306 is fixedly connected to the inner wall of the water trough 101.
[0041] Specifically, when the test block 10 needs water flow impact at different slopes, the second motor 1306 is started to drive the second threaded rod 1304 to rotate. The second threaded rod 1304 then drives the abutment plate 1301 to move to the left or right, thereby facilitating the adjustment of the angle of the inclined plate 7 and realizing the impact of water flow at different slopes on the test block 10.
[0042] The working principle of this utility model is as follows:
[0043] In use, the test block 10 is placed on the support plate 11, and water from the water tank 3 is discharged through the water outlet pipe 6. The discharged water enters the water flow channel 101. The test block 10 in the front water flow channel 101 is horizontally washed by the flowing water, while the water in the rear water flow channel 101 is impacted by the inclined plate 7 structure, thus realizing the water erosion resistance test of the test block 10 under different scenarios. The combination of the inlet tank 2, outlet tank 3, water pump 4, delivery pipe 401, drain pipe 5, and outlet pipe 6 facilitates the recycling of water resources. When it is necessary to measure the weight of the test block 10, the first motor 1208 is started to drive the rotating shaft 1207 and the second gear 1206 to rotate. The second gear 1206 then drives the first gear 1207 to rotate. The wheel 1205 and the first threaded rod 1201 rotate, which in turn drives the connecting frame 1101, the support plate 11, and the test block 10 to move upward. When the support plate 11 moves to be flush with the support plate 1213, the electric telescopic rod 1211 is activated to drive the push plate 1210 to move. The push plate 1210 then pushes the test block 10 to the weighing device 1214 for weighing, thereby recording the weight of the test block 10. When the test block 10 needs to be impacted by water flow at different slopes, the second motor 1306 is activated to drive the second threaded rod 1304 to rotate. The second threaded rod 1304 then drives the abutment plate 1301 to move to the left or right, thereby facilitating the adjustment of the angle of the inclined plate 7 and realizing the impact of water flow at different slopes on the test block 10.
[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
