[0035] The following is a detailed description of specific embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.

[0036] The following describes a multi-functional test platform according to the present invention with reference to the accompanying drawings.

[0037] As Figures 1 to 3As shown, in an embodiment of the present invention, a multi-functional test platform is provided for testing various performances of construction machinery. The multi-functional test platform includes a ramp module and a test module 300. The ramp module forms an inclined plane for the construction machinery to climb and is used to test the durability performance of the construction machinery. The inclination angle of the ramp module is adjustable. The test module 300 includes a plurality of test platform units detachably connected in sequence. The plurality of test platform units include an appearance test unit 30, a tipping load test unit 40, a passability test unit 50, a vibration test unit 60, and a deviation amount test unit 70. Among them, the ramp module and the test module 300, and any two adjacent test platform units are detachably connected through an alignment module 80.

[0038] The multi-functional test platform of the present application integrates multiple test units for testing different performances of construction machinery. For example, the appearance test unit 30 is used for measuring the appearance size test items of equipment or parts. The tipping load test unit 40 is used for testing the lifting force and tipping load of the equipment. The passability test unit 50 is used to complete the passability test of the equipment under specific working conditions. The vibration test unit 60 is used for the maintenance test items and equipment maintenance of the equipment in a vibrating state. The deviation amount test unit 70 is used to complete the equipment speed and deviation amount test. Moreover, the two modules, as well as any two adjacent test units, are detachably connected through the alignment module 80. In this way, when testing different equipment, the corresponding test units can be arbitrarily selected for combination to complete multiple tests, and single-item tests can also be completed. The modular design enables the test platform not to be restricted to a fixed site, facilitating transportation and assembly.

[0039] In an embodiment of the present invention, each of the plurality of test platform units includes a frame main body 301 and a test platform 302 provided on the frame main body 301. The test platform 302 is used to carry the construction machinery to be tested. The side end faces of the frame main bodies 301 of any two adjacent test platform units are detachably connected through the alignment module 80. When performing selective detachable connection, both the test module 300 and the ramp module are designed with alignment devices and alignment signal acquisition devices. The two devices work together to complete the alignment work of each platform unit module, improving the convenience of disassembly.

[0040] As Figure 11 shown, the alignment module 80 includes a guiding portion 81 and an introducing portion 84. One side of the guiding portion 81 facing the introducing portion 84 forms a trumpet-shaped guiding groove 82. Locking holes 83 are provided on both side walls of the trumpet-shaped guiding groove 82. The introducing portion 84 includes a bottom plate 85 and a convex block 86 provided on the bottom plate 85. Elastic locking portions 87 are provided on both sides of the convex block 86. The shape of the convex block 86 is adapted to the trumpet-shaped guiding groove 82. When the convex block 86 is guided and pushed into the trumpet-shaped guiding groove 82, the elastic locking portions 87 extend out of the locking holes 83 from the side walls of the trumpet-shaped guiding groove 82, so that the guiding portion 81 and the introducing portion 84 are locked.

[0041] As Figure 11 shown, during the alignment and installation process of the platform unit modules, the alignment signal acquisition devices installed on each platform unit module continuously feedback alignment signals to the terminal. By analyzing and judging the values, the attitude of the test platform unit module is adjusted. The guiding-in part 84 and the guiding part 81 are respectively installed on the platform unit module to be aligned. The guiding-in part 84 enters through the flared guiding groove 82 of the guiding part 81, and the elastic locking part 87 of the guiding-in part 84 pops out to lock the square locking hole 83 of the guiding part 81. A telescopic device is designed inside the guiding-in part 84, and a telescopic locking part is arranged on the guiding part 81. After the elastic locking part 87 is locked, the telescopic locking part locks and fixes the guiding-in part 84. Thus, the installation process of the test platform unit module is completed. This design improves the assembly efficiency of each test platform unit and more efficiently completes various tests. This structure can also ensure the gap between each platform module and guarantee the reliability of the small equipment test platform.

[0042] The unit modular assembly of the multifunctional test platform of the present application adopts an alignment device and an alignment signal acquisition device, which ensures that each test unit can be installed quickly, accurately and safely, improves the installation efficiency and safety. The alignment signal acquisition device gives real-time feedback during the alignment and installation process of the test platform, assists in improving the efficiency of the alignment device, and speeds up the assembly speed.

[0043] As Figure 4 shown, a dimension measurement assembly 31 is provided below the test platform 302 of the appearance test unit 30. Below the test platform 302, a first guide rail 32 extending in the horizontal direction, a second guide rail 33 extending in the front-rear direction, and a telescopic rod 34 extending in the height direction are provided. Both ends of the first guide rail 32 are slidably arranged below the second guide rail 33, and the telescopic rod 34 is slidably arranged on the first guide rail 32. The dimension measurement assembly 31 is installed on the telescopic rod 34 and is used to measure the external dimensions of the construction machinery carried on the test platform 302. In addition, a weight sensor is integrated at the bottom of the test platform 302 to measure the weight of the equipment on the test platform 302.

[0044] In the appearance test unit 30, through the cooperation of the first guide rail 32, the second guide rail 33 and the telescopic rod 34, the dimension measurement assembly 31 can have 6 degrees of freedom and can perform position adjustment in the up-down, front-back, left-right directions. The dimension measurement assembly 31 includes a mounting part slidably arranged on the telescopic rod 34 and a 360° steering measurement head arranged below the mounting part. Through the overall movement of the dimension measurement assembly 31, the measurement head can completely scan the outer periphery of the entire equipment, so that the external dimensions of the entire equipment can be obtained, and then the measurement of the external dimension test items of the equipment or parts can be completed. It can be seen that the dimension measurement assembly 31 located inside the frame main body 301 has a high degree of freedom and can measure all the external dimensions of parts and the whole machine.

[0045] As shown Figure 5 in the figure, on the upper surface of the test platform 302 of the tipping load test unit 40, a safety hook 41 and a blocking seat 42 are respectively provided along the width direction. One end of the construction machinery along the width direction is connected to the safety hook 41, and the other end is blocked inside the blocking seat 42. A support seat 43 is provided on the bottom wall of the frame body 301. The support seat 43 and the blocking seat 42 are arranged opposite to each other in the height direction. A mechanical measurement device 44 is also provided on the frame body 301. When measuring the tipping load of the construction machinery, one end of the mechanical measurement device 44 is hooked to the support seat 43, and the other end is used to connect to the outer end of the construction machinery and apply a pulling force to cause the construction machinery to tip. Among them, this mechanical test device can measure the magnitude of various forces. When conducting the tipping load project test, the safety hook 41 connected to the construction machinery is opened. Since a pulling force is applied to one end of the equipment, one end of the equipment applying the acting force tilts downward, and the other end lifts away from the test platform 302 by a certain angle. In this way, the tipping simulation test of the construction machinery can be realized, and the rising force and tipping load of the equipment can be obtained through the displayed value of the mechanical measurement device 44. Since the entire test is a simulated working condition, after the simulation is completed, the other end of the equipment is hooked to the safety hook 41 to ensure the stability of the entire equipment.

[0046] As shown Figure 6 in the figure, a spray pipe 45 is attached along the length direction on the top wall of the frame body 301, and spray pipes 45 extending along the height direction are attached to both inner side walls of the frame body 301. A plurality of spray heads are arranged at intervals along the length direction on the spray pipe 45. When it is necessary to conduct a rain test on the equipment, the equipment is placed inside the frame body 301, the spray heads are opened, and water is sprayed from the top and both sides of the frame body 301 to the outer periphery of the equipment respectively to simulate the rain working condition of the equipment.

[0047] As shown Figure 7 in the figure, a passability test channel 51 is provided inside the frame body 301 of the passability test unit 50, and the width and height of the passability test channel 51 are both adjustable. The height and width of the passability test channel 51 are both designed in the form of telescopic rods 34, so that both the height and width can be adjusted. When testing the passability performance of the equipment, the width and height of the passability test channel 51 are adjusted according to the size of the target equipment, and then the situation of the equipment passing through the passability test channel 51 under specific working conditions can be completed. Since both the height and width of the passability test channel 51 can be adjusted, it can be applicable to equipment of different sizes, improving the applicable range of the entire passability test unit 50.

[0048] As shown Figure 8As shown, a plurality of support rods 61 are arranged at intervals in the height direction of the frame body 301 of the vibration test unit 60. The plurality of support rods 61 can all perform up and down telescopic movements, so that the height of the entire test platform 302 can be adjusted. A plurality of support plates 62 are provided on the test platform 302, and a maintenance hole 63 for operators to operate is formed between the plurality of support plates 62.

[0049] When performing a vibration test, by controlling the plurality of support rods 61 to vibrate up and down continuously at a high frequency, a durability vibration test of the equipment can be carried out. Fixing devices are designed at the four corners of the platform for fixing the equipment. The distance between any two adjacent support plates 62 can be adjusted, so that the size of the maintenance hole 63 can be adjusted; when the plurality of support rods 61 lift the test platform 302 to a specified height or flip it by a certain angle, maintenance test items and equipment maintenance are carried out. The vibration test unit 60 of the present application is designed with a height adjustment and maintenance device. The application of the test platform 302 that can adjust the height enables the platform height to be adjusted to a comfortable height for the human body, and the overall angle of the platform can also be adjusted to adapt to different maintenance scenarios. By adjusting the distance between the two support plates 62, the size of the maintenance hole 63 can be adjusted arbitrarily to facilitate maintenance operations by maintenance personnel of different body types.

[0050] Moreover, during the vibration process, in order to keep the equipment on the test platform 302 stationary, clamping blocks for fixing the equipment are provided at the four corners of the test platform 302. The four clamping blocks fix the entire equipment to ensure that the entire equipment remains in its original position during the vibration process or when the test platform 302 is flipped, so as to ensure better test results.

[0051] Such as Figure 9As shown in the figure, two baffles 71 are arranged at intervals along the width direction on the test platform 302 of the deviation measurement unit 70. A plurality of rollers 72 are arranged in sequence along the length direction inside the two baffles 71. Displacement sensors and data acquisition devices are installed at both ends of each roller 72. When the construction machinery moves on the test platform 302, the two displacement sensors on each roller 72 can detect the end displacement of the construction machinery. The data acquisition device is electrically connected to the displacement sensor and is used to collect the displacement data of the end of the construction machinery detected by each displacement sensor. When the construction machinery moves on the test platform 302 at a preset standard speed, the lateral displacement amount of the construction machinery during the movement is judged by obtaining the displacement data, and then the deviation amount during the movement is measured according to the lateral displacement amount. In addition, in order to be applicable to different devices, adjusting devices are designed on both sides of each roller 72. The adjusting device can be used to adjust the distance between the two rollers 72 to meet the test requirements of different models or different types of devices. Displacement sensors and data acquisition devices are installed on each roller 72 of the present application, which ensures the accuracy of the data. The equipment speed test and deviation amount test can be completed in place, saving space. Moreover, the deviation measurement unit 70 is also equipped with a display system for displaying the displacement amount, and the data can be automatically displayed after the measurement is completed, which is convenient for users to read the data.

[0052] In an embodiment of the present invention, the slope module includes a staircase unit 100 and a slope unit 200 respectively connected to both ends of the test module 300 in the length direction. The staircase unit 100 is for testing the stair-climbing performance of the construction machinery, and the slope unit 200 located at the rear is for testing the climbing performance of the construction machinery. The staircase unit 100 includes a plurality of step parts 101 that go up step by step. The slope unit 200 includes an inclined slope surface. Vertical legs 201 are correspondingly installed below the end of the slope surface and each step part 101. The height direction of the vertical legs 201 is adjustable.

[0053] Among them, the staircase unit 100 can be used to simulate the stair-climbing working condition of the equipment and conduct equipment durability and departure angle tests. The slope unit 200 can simulate the climbing working condition of the equipment and complete equipment durability, departure angle, and climbing performance tests. The inclination angles of both the staircase unit 100 and the slope unit 200 can be adjusted according to test requirements. Specifically, the adjustment is carried out by using the vertical legs 201 arranged below.

[0054] As Figure 10 shown, the vertical leg 201 includes a support part 20 and a telescopic part 21. A hollow cylinder for the telescopic part 21 to insert is formed inside the support part 20. A plurality of elastic protrusions are arranged on the inner wall of the hollow cylinder along the height direction. A plurality of mounting holes are opened on the outer peripheral wall of the telescopic part 21. When the telescopic part 21 moves to a preset position inside the support part 20, the mounting holes can be locked with the corresponding elastic protrusions.

[0055] The angle of the staircase module can be adjusted according to the height of the platform unit module. The vertical leg 201 at the connection position between the staircase unit 100 and the test platform unit is an active adjustment device, and the rest are follow-up adjustment devices. The adjustment device is internally designed with a lifting device and externally added with a fixing device. The lifting device can adjust the height of the staircase tail, and then adjust the staircase angle. The installation form of the cross beam and column of the staircase unit 100 is a chute assembly structure, which can be slidably assembled up and down according to the staircase height to meet the test requirements. An alignment device is installed between the staircase module and the platform unit module, which can make the installation of the staircase and the test platform faster and more accurate.

[0056] As can be seen from the above, both the staircase unit 100 and the ramp unit 200 are designed with height adjustment devices and external fixing devices. Through the combination of the lifting system in the height adjustment device and the mechanical support structure of the external fixing device, the adjustment of the staircase angle is realized, and the load-bearing capacity of the staircase is ensured. The two units can be used to complete durability tests, departure angle tests, and climbing performance tests.
