[0022] This disclosure provides a test platform device for a heavy-duty device, including a load-bearing rotating base, a frame, a hydraulic output device, a mounting plate, a hydraulic connection mechanism, and a steering drive mechanism. The frame is connected to the load-bearing rotating base and is equipped with an electronically controlled test assembly for electrical connection to the electronic control system of the device body. The hydraulic output device is mounted on the frame. The mounting plate is connected to the power output end of the hydraulic output device, which drives the mounting plate to move vertically relative to the load-bearing rotating base. The mounting plate is used to mount a steering wheel mechanism, and when the hydraulic output device outputs pressure to the steering wheel mechanism, it drives the steering wheel mechanism to abut against the load-bearing rotating base through the mounting plate. The hydraulic connection mechanism is mounted on the mounting plate, with one end connected to the steering wheel mechanism and the other end connected to the hydraulic system of the device body. The steering drive mechanism is mounted on the mounting plate, with its power output end connected to the steering wheel mechanism, driving the steering wheel mechanism to rotate relative to the load-bearing rotating base. The steering drive mechanism is also electrically connected to the battery pack of the device body.

[0023] The aforementioned test platform equipment for heavy-duty devices, when the hydraulic output device outputs pressure to the steering wheel mechanism, drives the steering wheel mechanism to abut against the bearing rotating base body via the mounting plate to fix the steering wheel mechanism, so that the output pressure of the hydraulic output device acts on the steering wheel mechanism, and determines whether the steering wheel mechanism deforms under the output pressure, thus completing the steering wheel performance test of the heavy-duty device; a hydraulic connection mechanism is installed on the mounting plate body, one end of the hydraulic connection mechanism is used to connect to the steering wheel mechanism, and the other end of the hydraulic connection mechanism is used to connect to the hydraulic system of the device body, so that the hydraulic system of the device body is connected to the steering wheel mechanism through the hydraulic connection mechanism, and determines whether the steering wheel mechanism operates normally under the hydraulic system, thus completing the hydraulic system performance test of the heavy-duty device; the steering drive mechanism drives the steering wheel mechanism to rotate relative to the bearing rotating base body, and the steering drive mechanism is used to electrically connect to the battery pack of the device body, and determines the steering wheel mechanism's function in the steering drive mechanism. The system checks whether the load rotates to determine if the battery pack is discharging normally, thus completing the battery pack performance test of the heavy-duty device. The frame is equipped with an electronic control testing component, which is electrically connected to the electronic control system of the main body of the device.

This allows the testing platform equipment for the heavy-duty device to complete integrated testing of the heavy-duty device, thereby solving the problem that in the prior art, heavy-duty devices need to be tested through multiple independent testing devices. This also solves the problem of the complex testing process of heavy-duty devices in the prior art, simplifying the testing process under the integrated testing function of the testing platform equipment for heavy-duty devices. This saves testing time and reduces the testing time for heavy-duty devices, resulting in higher testing efficiency.

[0024] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments: like Figures 1 to 6As shown, a test platform device 10 for heavy-duty equipment in one embodiment includes a load-bearing rotating base 100, a frame 200, a hydraulic output device 300, a mounting plate 400, a hydraulic connection mechanism 500, and a steering drive mechanism 600. The frame 200 is connected to the load-bearing rotating base 100, and the frame 200 is provided with an electronically controlled test assembly 210, which is used to electrically connect to the electronic control system of the device body 30. The hydraulic output device 300 is mounted on the frame 200. The mounting plate 400 is connected to the power output end of the hydraulic output device 300, and the hydraulic output device 300 is used to drive the mounting plate 400 to move vertically up and down relative to the load-bearing rotating base 100. The mounting plate 400 is used for... When the hydraulic output device 300 outputs pressure to the steering wheel mechanism 20, it drives the steering wheel mechanism 20 to abut against the rotating support base 100 via the mounting plate 400. The hydraulic connection mechanism 500 is mounted on the mounting plate 400, with one end connected to the steering wheel mechanism 20 and the other end connected to the hydraulic system of the device body 30. The steering drive mechanism 600 is mounted on the mounting plate 400, with its power output end connected to the steering wheel mechanism 20. The steering drive mechanism 600 drives the steering wheel mechanism 20 to rotate relative to the rotating support base 100 and is electrically connected to the battery pack of the device body 30.

[0025] In this embodiment, when the hydraulic output device 300 outputs pressure to the steering wheel mechanism 20, it drives the steering wheel mechanism 20 to abut against the rotating support base 100 via the mounting plate 400, thereby fixing the steering wheel mechanism 20. One end of the hydraulic connection mechanism 500 is used to connect to the steering wheel mechanism 20, and the other end is used to connect to the hydraulic system of the device body 30, so that the hydraulic system of the device body 30 is connected to the steering wheel mechanism 20 through the hydraulic connection mechanism 500. The electronically controlled testing assembly 210 is a pressure pulse testing machine.

[0026] Furthermore, the steering wheel mechanism 20 is equipped with a hydraulic drive assembly 201. The hydraulic drive assembly 201 is connected to one end of the hydraulic system of the hydraulic connection mechanism 500 away from the main body 30 of the device. The hydraulic drive assembly 201 is used to drive the steering wheel mechanism 20 to rotate. That is, the hydraulic system of the main body 30 is connected to the hydraulic drive assembly 201 through the hydraulic connection mechanism 500, so that hydraulic oil flows into the hydraulic drive assembly 201 through the hydraulic connection mechanism 500. Under the action of the hydraulic oil, the hydraulic drive assembly 201 drives the steering wheel mechanism 20 to rotate. At this time, the steering wheel mechanism 20 operates normally under the hydraulic system. In this embodiment, the hydraulic drive assembly 201 is a drive motor.

[0027] The aforementioned test platform equipment 10 for heavy-duty devices, when the hydraulic output device 300 outputs pressure to the steering wheel mechanism 20, drives the steering wheel mechanism 20 to abut against the bearing rotating base 100 via the mounting plate 400, thereby fixing the steering wheel mechanism 20. This allows the output pressure of the hydraulic output device 300 to act on the steering wheel mechanism 20, determining whether the steering wheel mechanism 20 deforms under the output pressure, thus completing the steering wheel performance test of the heavy-duty device. A hydraulic connection mechanism 500 is installed on the mounting plate 400, with one end connected to the steering wheel mechanism 20 and the other end connected to the hydraulic system of the device body 30. This allows the hydraulic system of the device body 30 to be connected to the steering wheel mechanism 20, determining whether the steering wheel mechanism 20 operates normally under the hydraulic system, thus completing the hydraulic system performance test of the heavy-duty device. A steering drive mechanism 600 drives the steering wheel mechanism 20 to rotate relative to the bearing rotating base 100. The steering drive mechanism 600 is electrically connected to the battery pack of the device body 30, determining whether the steering wheel mechanism... Whether the structure 20 rotates under the action of the steering drive mechanism 600 is used to determine whether the battery pack is discharging normally, so as to complete the battery pack performance test of the heavy-duty device; the frame body 200 is provided with an electronic control test component 210, which is used to electrically connect with the electronic control system of the device body 30, and to determine whether there is a pressure pulse signal in the electronic control test component 210, so as to complete the performance test of the electronic control system of the heavy-duty device. This allows the test platform equipment 10 for the heavy-duty device to complete the integrated test of the heavy-duty device, thereby solving the problem that the heavy-duty device needs to be tested by multiple independent test equipment in the prior art, that is, solving the problem that the test process of the heavy-duty device in the prior art is relatively complicated. Under the integrated test of the test platform equipment 10 for the heavy-duty device, the test process of the heavy-duty device is simplified, which helps to save test time, thus making the test time of the test platform equipment 10 for the heavy-duty device shorter, and thus making the test efficiency of the test platform equipment 10 for the heavy-duty device higher.

[0028] like Figures 1 to 6As shown, in one embodiment, the rotating support base 100 includes a support base portion 110 and a turntable portion 120, with the turntable portion 120 rotatably connected to the support base portion 110; the frame body 200 is connected to the support base portion 110; and the hydraulic output device 300 is used to drive the steering wheel mechanism 20 to abut against the turntable portion 120 through the mounting plate 400 when outputting pressure to the steering wheel mechanism 20. In this embodiment, the turntable 120 is rotatably connected to the support base 110. When the hydraulic output device 300 outputs pressure to the steering wheel mechanism 20, it drives the steering wheel mechanism 20 to abut against the turntable 120 through the mounting plate 400. When the turntable 120 needs to rotate, the steering wheel mechanism 20 can rotate by friction. When the turntable 120 needs to be locked, it is only necessary to output a predetermined pressure to the steering wheel mechanism 20 through the hydraulic output device 300 to lock the steering wheel mechanism 20. At this time, the hydraulic clamping force on the steering wheel mechanism 20 remains unchanged, thereby achieving braking of the turntable 120 through friction. Therefore, there is no need to add an independent braking mechanism, which effectively simplifies the overall structure and makes the test platform equipment 10 for heavy-duty devices compact.

[0029] like Figures 1 to 2 As shown, in one embodiment, the mounting plate 400 is slidably connected to the frame 200, which makes the movement between the mounting plate 400 and the frame 200 more convenient.

[0030] like Figures 1 to 2 As shown, in one embodiment, a first sliding groove 220 is provided at one end of the frame body 200, and a second sliding groove 230 is provided at the other end of the frame body 200; a first sliding part 410 is provided at one end of the mounting plate body 400, and a second sliding part 420 is provided at the other end of the mounting plate body 400. The first sliding part 410 passes through the first sliding groove 220 and is slidably connected to the frame body 200, and the second sliding part 420 passes through the second sliding groove 230 and is slidably connected to the frame body 200, so that the mounting plate body 400 slides relative to the frame body 200, and the sliding between the mounting plate body 400 and the frame body 200 is convenient.

[0031] like Figures 1 to 6As shown, in one embodiment, the hydraulic output device 300 includes a hydraulic power mechanism 310, a hydraulic circuit assembly 320, and a hydraulic actuator 330. The hydraulic circuit assembly 320 is connected to both the hydraulic power mechanism 310 and the hydraulic actuator 330. Both the hydraulic power mechanism 310 and the hydraulic actuator 330 are mounted on the frame body 200. The mounting plate 400 is connected to the power output end of the hydraulic actuator 330. The hydraulic actuator 330 is used to drive the mounting plate 400 to move vertically up and down relative to the bearing rotating base body 100. When the hydraulic actuator 330 outputs pressure to the steering wheel mechanism 20, it drives the steering wheel mechanism 20 to abut against the bearing rotating base body 100 through the mounting plate 400. In this embodiment, the hydraulic actuator 330 is used to drive the mounting plate 400 to move vertically up and down relative to the bearing rotating base 100. The mounting plate 400 is used to mount the steering wheel mechanism 20, which can ensure that the contact surfaces of the steering wheel mechanism 20 and the turntable part 120 are completely parallel when they are in contact, so that the clamping force between the steering wheel mechanism 20 and the turntable part 120 is uniform, thereby avoiding problems such as uneven wear of the steering wheel mechanism 20, and making the fit between the steering wheel mechanism 20 and the turntable part 120 more uniform.

[0032] like Figures 1 to 6 As shown, in one embodiment, the hydraulic circuit assembly 320 includes a first hydraulic oil supply pipe (not shown), a hydraulic control valve group 322, a second hydraulic oil supply pipe 323, and a hydraulic return pipe 324. The first hydraulic oil supply pipe is connected to the hydraulic power mechanism 310 and the hydraulic control valve group 322, the second hydraulic oil supply pipe 323 is connected to the hydraulic control valve group 322 and the hydraulic actuator 330, and the hydraulic return pipe 324 is connected to the hydraulic actuator 330 and the hydraulic power mechanism 310. In this embodiment, the first hydraulic oil supply pipe is connected to the hydraulic power mechanism 310 and the hydraulic control valve group 322 respectively, and the second hydraulic oil supply pipe 323 is connected to the hydraulic control valve group 322 and the hydraulic actuator 330 respectively. That is, the hydraulic control valve group 322 is connected in series in the middle of the oil supply circuit, which can isolate the load fluctuation of the hydraulic power end and independently adjust the pressure and flow output to the hydraulic actuator 330. It can fully match the high-precision control requirements of the hydraulic actuator 330 on the output pressure of the steering wheel mechanism 20, thereby effectively avoiding problems such as slippage or uneven wear of the steering wheel mechanism 20, and making the output pressure of the hydraulic actuator 330 on the steering wheel mechanism 20 highly accurate.

[0033] like Figures 1 to 2 As shown, in one embodiment, the hydraulic power mechanism 310 is a hydraulic station structure, which makes the hydraulic power mechanism 310 highly reliable in operation.

[0034] like Figures 2 to 5As shown, in one embodiment, the hydraulic actuator 330 includes a mounting base 331, a hydraulic cylinder 332, and a connecting assembly 333. The hydraulic cylinder 332 is mounted on the mounting base 331, which is mounted on the frame 200. The connecting assembly 333 is connected to the power output end of the hydraulic cylinder 332. The hydraulic cylinder 332 drives the connecting assembly 333 to move. The connecting assembly 333 is connected to the mounting plate 400. In this embodiment, the hydraulic cylinder 332 outputs a load pressure of 5-20t to the steering wheel mechanism 20. The connecting assembly 333 is connected to the power output end of the hydraulic cylinder 332, that is, the connecting assembly 333 is connected to the piston rod of the hydraulic cylinder 332, which makes the transmission reliability between the connecting assembly 333 and the hydraulic cylinder 332 high.

[0035] Furthermore, in one embodiment, the hydraulic cylinder 332 is equipped with an overload relief valve (not shown), which effectively avoids the problem of overload of the hydraulic cylinder 332 and makes the hydraulic cylinder 332 safer to use.

[0036] Furthermore, in one embodiment, the second hydraulic oil supply pipe 323 is connected to the hydraulic control valve group 322 and the hydraulic cylinder 332 respectively, and the hydraulic oil return pipe 324 is connected to the hydraulic cylinder 332 and the hydraulic power mechanism 310 respectively, so as to realize the precise control of the action of the hydraulic cylinder 332 and make the movement accuracy of the hydraulic cylinder 332 high.

[0037] like Figures 1 to 6 As shown, in one embodiment, the steering drive mechanism 600 includes a base 610, a steering drive motor 620, a drive gear 630, and a driven gear 640. The steering drive motor 620 is mounted on the base 610, and the base 610 is mounted on the mounting plate 400. The drive gear 630 is connected to the power output end of the steering drive motor 620, and the steering drive motor 620 drives the drive gear 630 to rotate. The drive gear 630 meshes with the driven gear 640, and the driven gear 640 is rotatably connected to the mounting plate 400. The driven gear 640 is connected to the steering wheel mechanism 20, so that the mounting plate 400 is used to mount the steering wheel mechanism 20 through the driven gear 640. The steering drive motor 620 is electrically connected to the battery pack of the device body 30. In this embodiment, the driving gear 630 is connected to the power output end of the steering drive motor 620, and the driving gear 630 is meshed with the driven gear 640, resulting in a very short transmission chain and a small transmission gap. This makes the power loss of the steering drive mechanism 600 extremely low, while the torque carrying capacity of the gear transmission is strong, which can meet the steering power requirements of the steering wheel mechanism 20, making the testing platform equipment 10 for heavy-duty devices more convenient to test.

[0038] Furthermore, in one embodiment, the steering drive motor 620 drives the active gear 630 to rotate at an angular velocity of 0.1-10° / s, which makes the steering drive motor 620 have good steering adjustment performance for the steering wheel mechanism 20 through the active gear 630 and the driven gear 640.

[0039] like Figures 3 to 4 As shown, in one embodiment, the diameter of the driving gear 630 is smaller than the diameter of the driven gear 640, which makes the transmission accuracy between the driving gear 630 and the driven gear 640 higher, thereby making the steering wheel mechanism 20 more accurate.

[0040] Furthermore, such as Figure 6 As shown, in one embodiment, the hydraulic output device 300 further includes a hydraulic off-center loading mechanism 340, which is disposed adjacent to the hydraulic cylinder 332. The hydraulic off-center loading mechanism 340 is connected to the hydraulic oil circuit assembly 320 and is mounted on the mounting base 331. The connecting assembly 333 is connected to the power output end of the hydraulic off-center loading mechanism 340. The hydraulic off-center loading mechanism 340 is used to drive the connecting assembly 333 to move. When the hydraulic off-center loading mechanism 340 outputs pressure to the steering wheel mechanism 20, it drives the steering wheel mechanism 20 to abut against the bearing rotating base 100 through the mounting plate 400. In this embodiment, the hydraulic off-center loading mechanism 340 is an off-center loading hydraulic cylinder. The hydraulic off-center loading mechanism 340 is used to output a load pressure of 5-20t to the steering wheel mechanism 20. The hydraulic off-center loading mechanism 340 is used to automatically compensate for the output pressure. That is, when the center of gravity of the steering wheel mechanism 20 is offset or the force is uneven, the hydraulic off-center loading mechanism 340 can automatically adjust the output pressure through the oil circuit pressure, thereby effectively ensuring that the contact pressure between the steering wheel mechanism 20 and the bearing rotating base body 100 is always uniform, so that the test platform equipment 10 for heavy load device has good test performance on the steering wheel mechanism 20.

[0041] Furthermore, in one embodiment, the hydraulic circuit assembly 320 also includes an off-center load supply pipe (not shown) and an off-center load return pipe (not shown). The off-center load supply pipe is connected to the hydraulic control valve group 322 and the hydraulic off-center load mechanism 340, respectively, and the off-center load return pipe is connected to the hydraulic off-center load mechanism 340 and the hydraulic power mechanism 310, respectively, to form an independent off-center load circuit, so that the control accuracy of the hydraulic off-center load mechanism 340 is high.

[0042] Compared with the prior art, this disclosure has at least the following advantages: When the hydraulic output device 300 outputs pressure to the steering wheel mechanism 20, it drives the steering wheel mechanism 20 to abut against the bearing rotating base 100 via the mounting plate 400, thus fixing the steering wheel mechanism 20. This allows the output pressure of the hydraulic output device 300 to act on the steering wheel mechanism 20, determining whether the steering wheel mechanism 20 deforms under the output pressure, thereby completing the steering wheel performance test of the heavy-duty device. The hydraulic connection mechanism 500 is mounted on the mounting plate 400. One end of the hydraulic connection mechanism 500 is connected to the steering wheel mechanism 20, and the other end is connected to the hydraulic system of the device body 30, allowing the hydraulic system of the device body 30 to be connected to the steering wheel mechanism 20. This determines whether the steering wheel mechanism 20 operates normally under the hydraulic system, thereby completing the hydraulic system performance test of the heavy-duty device. The steering drive mechanism 600 drives the steering wheel mechanism 20 to rotate relative to the bearing rotating base 100. The steering drive mechanism 600 is electrically connected to the battery pack of the device body 30, determining whether the steering wheel mechanism 20 rotates under the steering drive mechanism. The system checks whether the structure 600 rotates under its influence to determine whether the battery pack is discharging normally, thus completing the battery pack performance test of the heavy-duty device. The frame 200 is equipped with an electronic control test component 210, which is electrically connected to the electronic control system of the device body 30. The system checks whether the electronic control test component 210 has a pressure pulse signal to complete the performance test of the electronic control system of the heavy-duty device. This allows the test platform equipment 10 for the heavy-duty device to complete the integrated test of the heavy-duty device, thereby solving the problem that the heavy-duty device in the prior art needs to be tested by multiple independent test equipment. This solves the problem that the test process of the heavy-duty device in the prior art is relatively complicated. Under the integrated test function of the test platform equipment 10 for the heavy-duty device, the test process of the heavy-duty device is simplified, which helps to save test time. As a result, the test time of the test platform equipment 10 for the heavy-duty device is shorter, and the test efficiency of the test platform equipment 10 for the heavy-duty device is higher.
