Description

Technical Field

[0001] This invention relates to the field of sanitation vehicle testing, specifically to a suction cup simulation test device for sweeper trucks. Background Technology

[0002] When cleaning roads, sweeper trucks use a suction system to remove garbage from the road surface. Therefore, the suction efficiency (the ratio of the mass of remaining garbage to the total mass of garbage) is an important indicator for evaluating the quality of sweeper trucks. In existing technologies, the suction performance of sweeper trucks is generally tested on an asphalt road constructed in an open-air area. Before testing, a certain mass of garbage is spread on the test road. After the test vehicle operates at a specified speed, the remaining garbage on the road is manually collected to calculate the suction efficiency. However, this testing method requires the complete assembly of the vehicle and the setting up of a separate test road, which is time-consuming, labor-intensive, and has a long development cycle. Summary of the Invention

[0003] In view of this, the present invention provides a suction cup simulation test device for sweeper trucks to solve the problems of time-consuming and labor-intensive testing of suction cups for sweeper trucks and long development cycles in the prior art.

[0004] This invention provides a simulation test device for a sweeper truck suction cup, comprising: a test platform, on which a suction cup to be tested is adapted to be mounted; a waste disposal structure, disposed on the test platform and corresponding to the platform surface; a weighing structure, disposed on the test platform and corresponding to the discharge port of the waste disposal structure; and a rotation drive unit, adapted to drive the test platform or the suction cup to be tested to rotate, so that the suction cup to be tested rotates relative to the platform surface of the test platform and passes over the weighing structure.

[0005] Beneficial effects: By quantitatively disposing of waste onto the weighing structure through the waste disposal structure, the tested suction cup rotates relative to the test platform, passing over the weighing structure and sucking up the waste. The weight of the remaining waste can be directly displayed through the weighing structure, thus making it easy to calculate the suction efficiency of the tested suction cup. The test results are more realistic and reliable. Furthermore, there is no need to assemble the tested suction cup onto the vehicle or set up a separate test road, saving time and effort and shortening the development cycle.

[0006] In one optional embodiment, the sweeper suction cup simulation test device further includes an obstacle, which is set on the test platform.

[0007] Beneficial effects: By setting obstacles on the moving path of the test bench, the impact of road obstacles on the suction cup under test during use can be simulated. Therefore, it is possible to test the rigidity of the suction cup under test and test its service life.

[0008] In one alternative embodiment, the obstacles are arranged at circumferential intervals along the test bench.

[0009] In one optional embodiment, the sweeper suction cup simulation test device further includes a speed bump, which is disposed on the test bench.

[0010] Beneficial effects: By setting speed bumps on the moving path of the test bench, the situation of the tested suction cup passing through road speed bumps during use can be simulated, which can further improve the stiffness and strength test of the tested suction cup and ensure the authenticity of the stiffness and strength test results.

[0011] In one alternative embodiment, the speed bumps are arranged at multiple intervals along the circumference of the test bench.

[0012] In one optional embodiment, the sweeper suction cup simulation test device further includes a suction cup frame, the rotation drive unit is disposed on the test bench and adapted to drive the suction cup frame to rotate, and the suction cup to be tested is adapted to be disposed on the suction cup frame.

[0013] Beneficial effects: By driving the suction cup holder to rotate, the suction cup under test is driven to rotate synchronously. The driving method is simple and easy to operate.

[0014] In one optional embodiment, the sweeper suction cup simulation test device further includes a support wheel structure, which is connected to the suction cup frame and adapted to roll into contact with the test platform.

[0015] Beneficial effect: By setting up a support wheel structure, the stability of the tested suction cup during rotation is ensured.

[0016] In one optional embodiment, the rotation drive unit is provided at one end of the suction cup frame, and the support wheel structure is provided at the other end of the suction cup frame.

[0017] In one optional embodiment, the test bench has a frustum-shaped structure, and the drive shaft of the rotation drive unit is set corresponding to the center of the test bench.

[0018] In one alternative embodiment, the rotation drive unit is provided with a counting unit adapted to detect the number of rotations of the rotation drive unit.

[0019] Beneficial effect: By counting the number of rotations of the rotating drive, the stroke length of the tested suction cup can be calculated, which can be used to test the rigidity of the tested suction cup. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] The following is combined Figure 1 and Figure 2 The following describes embodiments of the present invention.

[0027] According to an embodiment of the present invention, a simulation test device for a sweeper truck suction cup is provided, comprising a test bench 1, a waste disposal structure 2, a weighing structure 3, and a rotation drive unit 4. The test bench 1 is adapted to mount a suction cup 10 to be tested. The waste disposal structure 2 is disposed on the test bench 1 and corresponds to the surface of the test bench 1. The weighing structure 3 is disposed on the test bench 1 and corresponds to the discharge port of the waste disposal structure 2. The rotation drive unit 4 is adapted to drive the test bench 1 or the suction cup 10 to rotate, so that the suction cup 10 rotates relative to the surface of the test bench 1 and passes over the weighing structure 3.

[0028] Waste is quantitatively disposed of on the weighing structure 3 through the waste disposal structure 2. As the tested suction cup 10 rotates relative to the test platform 1, it passes over the weighing structure 3 and removes the waste. The weight of the remaining waste can be directly displayed through the weighing structure 3, thus making it easy to calculate the suction efficiency of the tested suction cup 10. The test results are more realistic and reliable. Furthermore, there is no need to assemble the tested suction cup 10 onto the vehicle or set up a separate test road, saving time and effort and shortening the development cycle.

[0029] It is worth noting that in related technologies, a recyclable conveyor belt is used to simulate a road surface. During the belt's circulation, relative motion occurs between the belt and the suction cup 10 under test, thereby testing the suction efficiency of the suction cup 10. However, the conveyor belt itself is a flexible structure, resulting in low matching with actual road conditions and affecting the accuracy of the test results. In this embodiment, a test bench 1 is used to simulate the road surface, which can match real road conditions more closely, ensuring the accuracy and authenticity of the test results.

[0030] It should be noted that the suction cup 10 under test is connected to an external negative pressure pipe, and the amount of negative pressure in the pipe can be adjusted to simulate the actual working conditions of the suction cup 10 under test.

[0031] In one embodiment, such as Figure 1 As shown, the weighing structure 3 is set on the platform of the test bench 1.

[0032] Of course, in other alternative implementations, the weighing structure 3 can be integrated inside the test bench 1 to enable the test bench 1 to have a weighing function.

[0033] In one embodiment, such as Figure 1 As shown, the rotation drive unit 4 can drive the suction cup 10 under test to rotate. Specifically, the suction cup simulation test device for sweeper trucks also includes a suction cup frame 7. The rotation drive unit 4 is set on the test bench 1 and is adapted to drive the suction cup frame 7 to rotate. The suction cup frame 7 is adapted to be mounted on the suction cup 10 under test. By driving the suction cup frame 7 to rotate, the suction cup 10 under test is driven to rotate synchronously. The driving method is simple and easy to operate.

[0034] Of course, in other alternative embodiments, the position of the suction cup holder 7 can be kept stationary, and the test bench 1 can be rotated using the rotation drive unit 4. Specifically, the test bench 1 and the suction cup holder 7 are rotatably connected, and the rotation drive unit 4 is driven and connected to the test bench 1.

[0035] In one embodiment, such as Figure 1 and Figure 2 As shown, the sweeper truck suction cup simulation test device also includes a support wheel structure 8, which is connected to the suction cup frame 7 and adapted to roll into contact with the test platform 1. By setting the support wheel structure 8, the stability of the suction cup 10 under test during rotation is ensured.

[0036] Specifically, such as Figure 1 As shown, the rotation drive unit 4 is provided at one end of the suction cup frame 7, and the support wheel structure 8 is provided at the other end of the suction cup frame 7. Therefore, it is possible to prevent the suction cup frame 7 from forming a cantilever structure and to prevent the suction cup frame 7 from deforming.

[0037] In one embodiment, such as Figure 1 and Figure 2 As shown, the support structure 8 includes a support rod 801 and a roller 802. The upper end of the support rod 801 is connected to the suction cup frame 7, and the roller 802 is provided at the lower end of the support rod 801.

[0038] In one embodiment, such as Figure 1 As shown, the suction cup holder 7 includes a connecting shaft 701 and a crossbeam 702. The lower end of the connecting shaft 701 is connected to the drive shaft of the rotation drive unit 4, one end of the crossbeam 702 is connected to the upper end of the connecting shaft 701, and the upper end of the support rod 801 is connected to the other end of the crossbeam 702.

[0039] In one embodiment, such as Figure 1 As shown, the test bench 1 has a frustum-shaped structure, and the drive shaft of the rotation drive unit 4 is set at the center of the test bench 1. Therefore, the movement path of the suction cup 10 under test is concentric with the test bench 1, which makes it easier for the test bench 1 and the suction cup 10 under test to be matched.

[0040] Of course, in other alternative implementations, the test bench 1 can also be of other shapes, as long as the surface area of ​​the test bench 1 can cover the movement path of the suction cup 10 being tested.

[0041] In one embodiment, the rotary drive unit 4 is provided with a counting unit adapted to detect the number of rotations of the rotary drive unit 4. By counting the number of rotations of the rotary drive unit 4, the stroke length of the suction cup 10 under test can be calculated for use in testing the rigidity of the suction cup 10 under test.

[0042] In one embodiment, the rotation drive unit 4 is a motor.

[0043] It is worth noting that by adjusting the motor speed, the test suction cup 10 can be simulated to travel at different speeds.

[0044] In one embodiment, such as Figure 1 As shown, the sweeper suction cup simulation test device also includes an obstacle 5, which is set on the test bench 1. By setting the obstacle 5 on the moving path of the test bench 1, the impact of the suction cup 10 under test on the road obstacle 5 during use can be simulated. Therefore, the rigidity of the suction cup 10 under test can be tested, and the service life of the suction cup 10 under test can be tested.

[0045] In one embodiment, such as Figure 1 As shown, obstacles 5 are arranged at intervals along the circumference of the test bench 1.

[0046] It is worth noting that obstacle 5 can be a stone, and / or a rubber block, and / or a cast iron block. Understandably, obstacle 5 mainly simulates some items that the suction cup will come into contact with during actual operation, such as stones (bricks), soft garbage, and hard garbage, to improve the realism of the sweeper suction cup simulation test.

[0047] It is worth noting that the length of obstacle 5 ranges from 200mm to 400mm, the width from 100mm to 200mm, and the height from 40mm to 100mm. Along the rotation direction of the suction cup 10 under test, the included angle α between adjacent obstacles 5 ranges from 45° to 180°. Furthermore, the position of obstacle 5 along the radial direction of the test platform 1 can be changed. Therefore, the stiffness of the suction cup at different locations can be tested, as well as the stiffness and durability of the suction cup under different impact frequencies.

[0048] In one embodiment, such as Figure 1 As shown, the sweeper suction cup simulation test device also includes a speed bump 6, which is set on the test bench 1. By setting the speed bump 6 on the movement path of the test bench 1, the situation of the suction cup 10 being tested passing through the road speed bump 6 during use can be simulated, further improving the rigidity test of the suction cup 10 and ensuring the authenticity of the rigidity test results.

[0049] In one embodiment, such as Figure 1 As shown, several speed bumps 6 are arranged at intervals along the circumference of the test bench 1.

[0050] It is worth noting that the speed bump 6 can be a rubber speed bump 6 and / or a cast iron speed bump 6. The speed bump 6 is mainly arranged based on the rubber speed bump 6 and cast iron speed bump 6 commonly found on actual road surfaces to improve the realism of the sweeper truck suction cup simulation test.

[0051] It is worth noting that the length of the speed bump 6 ranges from 2500mm to 3000mm, the width from 200mm to 300mm, and the height from 50mm to 100mm. Along the rotation direction of the suction cup 10 being tested, the included angle β between adjacent speed bumps 6 ranges from 45° to 180°. Therefore, the stiffness and durability of the suction cup can be tested under the impact frequency of the same or different types of speed bumps 6.

[0052] It should be noted that the obstacle 5 and / or speed bump 6 can be connected to the test bench 1 by magnetic attraction. By setting an appropriate magnetic attraction force or controlling the on / off state of the magnetism, it is possible to ensure a stable connection between the obstacle 5 and / or speed bump 6 and the test bench 1, and also to facilitate the replacement of the obstacle 5 and / or speed bump 6 or the change of the position of the obstacle 5 and / or speed bump 6.

[0053] In one embodiment, the waste disposal structure 2 is a screw feeder structure, which enables quantitative waste disposal.

[0054] When using the sweeper suction cup simulation test device of this embodiment, firstly, a certain amount of garbage is placed into the weighing structure 3 using the garbage disposal structure 2; then, the rotation drive unit 4 is activated, causing the rotation drive unit 4 to drive the suction cup frame 7 to rotate, so that the suction cup 10 under test passes over the weighing structure 3 and removes a portion of the garbage. The weighing structure 3 can display the weight of the remaining garbage, and the suction efficiency of the suction cup 10 under test can be calculated; furthermore, the suction cup 10 under test passes over the obstacle 5 and the speed bump 6 during rotation (it can pass through once or multiple times), and it is observed whether the suction cup 10 under test deforms or breaks; the suction cup 10 under test passes through the obstacle 5 and the speed bump 6 continuously for a long time to perform a durability test on the suction cup 10 and test the service life of the suction cup.
