[0027] The technical solution of the present application will be described in detail below with reference to the accompanying drawings and in combination with the implementation modes.

[0028] According to one aspect of the present application, a Ferris wheel walking nylon wheel load-bearing performance testing device is provided, characterized in that the Ferris wheel walking nylon wheel load-bearing performance testing device comprises a track portion 10, a walking mechanism 20, a testing mechanism 30 and a control unit, the walking mechanism 20 comprises a main body 21 and a driving portion 22 installed on the main body 21, the main body 21 is used for detachably installing a Ferris wheel walking nylon wheel 40, the driving portion 22 is used for driving the main body 21 so that the Ferris wheel walking nylon wheel 40 rolls along the track portion 10, the testing mechanism 30 is used for applying pressure to the main body 21 toward the track portion 10 so that the Ferris wheel walking nylon wheel 40 presses the track portion 10, and the control unit is electrically connected to the testing mechanism 30 to control the operation of the testing mechanism 30.

[0029] In the Ferris wheel nylon wheel load-bearing performance testing device of the present application, pressure can be applied to the main body 21 through the testing mechanism 30, and then the pressure can be transmitted to the Ferris wheel nylon wheel 40, so that the Ferris wheel nylon wheel 40 rolls along the track portion 10 under pressure. The operation of the testing mechanism 30 can be controlled by the control unit, and the loading of the testing mechanism 30 can be controlled during the test until the Ferris wheel nylon wheel 40 meets the safety requirements or cracks to complete the test.

[0030] Specifically, when the test mechanism 30 is loaded so that the ratio of the bearing pressure of the Ferris wheel nylon wheel 40 to the design rated load (i.e., the safety factor) is not less than 3.5 and the Ferris wheel nylon wheel 40 is not cracked, it means that the Ferris wheel nylon wheel 40 is qualified. When the Ferris wheel nylon wheel 40 is cracked when the ratio of the bearing pressure to the design rated load does not reach 3.5, it means that it is unqualified.

[0031] To ensure the normal progress of the test, it is necessary to monitor the pressure applied by the test mechanism 30. To this end, the test mechanism 30 includes a detection unit for feeding back the pressure applied by the test mechanism 30. Specifically, the detection unit can be in an appropriate form, such as a pressure sensor.

[0032] During the test, it is necessary to make the Ferris wheel nylon wheel 40 always roll along the track portion 10. Since the test process is long, it is necessary to make the Ferris wheel nylon wheel 40 roll a long distance along the track portion 10. In order to simplify the structure and save space, the walking mechanism 20 can be reciprocated along the track portion 10. Preferably, the control unit can be configured to control the walking mechanism 20 to reciprocate along the track portion 10. Specifically, the control unit can be electrically connected to the drive unit 22 to control the operation of the drive unit 22. In addition, detection elements such as proximity switches electrically connected to the control unit can be provided at both ends of the track portion 10 to feedback a signal to the control unit when it is detected that the walking mechanism 20 moves to the end of the track portion 10. The control unit can control the drive unit 22 to switch the moving direction of the walking mechanism 20 according to the feedback signal.

[0033] In the present application, the driving part 22 may be in a suitable form, for example, it may include a motor 221 and a driving wheel 222 driven by the motor 221, the track part 10 may be provided with a friction track 11, and the driving wheels 222 may be provided in pairs and roll along the two sides of the friction track 11 respectively. Figure 1 and Figure 5In the illustrated embodiment, two driving wheels 222 are provided, and the driving directions of the motors 221 of the two driving wheels 222 are opposite, that is, when moving from one end to the other end along the track portion 10, one of the motors 221 drives the corresponding driving wheel 222 to rotate, and the other motor 221 stops, and its corresponding driving wheel 222 is driven, so that the walking mechanism 20 moves from one end to the other end of the track portion 10. In order to make the walking mechanism 20 move smoothly, the main body 21 can also be equipped with auxiliary wheels 24, so that it can roll along the two sides of the friction track 11 driven by the driving wheels 222.

[0034] The track portion 10 can be arranged as required. To ensure the stable movement of the walking mechanism 20, preferably, the friction track 11 is arranged in the middle of the width direction of the track portion 10, and the walking tracks 12 corresponding to the Ferris wheel walking nylon wheels 40 are symmetrically arranged on both sides thereof. Correspondingly, the main body 21 may include a longitudinal frame 211 arranged in the longitudinal direction, a transverse frame 212 arranged at both ends of the longitudinal frame 211, and a connecting frame 213 connecting the corresponding ends of the transverse frame 212. The motor 221 may be installed on the longitudinal frame 211, the Ferris wheel walking nylon wheels 40 are installed on the ends of the transverse frame 212, and the testing mechanism 30 may be connected to the middle of the connecting frame 213.

[0035] During the test, it is necessary to increase the loaded pressure after the Ferris wheel nylon wheel 40 is loaded with a certain pressure and rolls normally for a predetermined time, so as to obtain the load-bearing pressure of the Ferris wheel nylon wheel 40 and obtain the safety factor accordingly. To this end, the control unit is configured to control the test mechanism 30 to perform a normal pressure test and a boost test in sequence, so as to keep the pressure of the test mechanism 30 constant during the normal pressure test and gradually increase the pressure of the test mechanism 30 during the boost test. In the normal pressure test, the test mechanism 30 can apply a normal load (i.e., a designed rated load) corresponding to the normal operation of the Ferris wheel. In the normal pressure test, the test mechanism 30 can be loaded with a normal load for a first preset time (e.g., 6h-8h). In the boost test, the loaded pressure can be gradually increased for testing. For example, in the step-by-step pressure test, each time the pressure is increased, the test time under the pressure can be a second preset time (e.g., more than 30 minutes). In addition, the pressure increase value of each test mechanism 30 can be the same or different, and can be specifically set according to the actual test situation.

[0036] Among them, Figure 6 As shown, a stopper 13 may be provided at the end of the track portion 10 to prevent the running mechanism 20 from moving outside the track portion 10. A detection element for detecting whether the running mechanism 20 is close to the end of the track portion 10 may also be provided on the stopper 13.

[0037] In the present application, the testing mechanism 30 may be in a suitable form to apply a controllable pressure to the walking mechanism 20. Figure 8 and Fig. 9 In the embodiment shown, the testing mechanism 30 may include a telescopic cylinder 31 and a first pressing wheel 32. One end of the telescopic cylinder 31 is connected to the main body 21, and the other end is connected to the first pressing wheel 32. The first pressing wheel 32 abuts against the lower side of the track portion 10. The first pressing wheel 32 may be mounted on a mounting frame 34 via a wheel axle 33. The mounting frame 34 is mounted to the other end of the telescopic cylinder 31. In order to evenly apply pressure to the main body 21, preferably, as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the testing mechanisms 30 may be symmetrically arranged on both sides of the moving direction of the traveling mechanism 20 , and the first pressing wheels 32 of the two testing mechanisms 30 share a wheel axle 33 .

[0038] Through the telescopic cylinder 31 and the first pressing wheel 32 , the testing mechanism 30 can press the traveling mechanism 20 and the track portion 10 from both sides, thereby applying the pressure required for the test to the Ferris wheel traveling nylon wheel 40 .

[0039] The telescopic cylinder 31 may be in an appropriate form, and in order to facilitate the control of its operation, the telescopic cylinder 31 may be a hydraulic cylinder. In addition, as described above, the control unit may control the test mechanism 30 to increase the pressure when the walking mechanism 20 moves in the reverse direction. To this end, the hydraulic system of the hydraulic cylinder may be provided with a proportional valve, and the control unit is configured to be able to control the proportional valve so as to accurately control the output pressure of the hydraulic cylinder. In addition, in order to provide real-time feedback on the actual output pressure of the hydraulic cylinder, the detection unit may include a pressure sensor disposed at the front end of the rodless chamber of the hydraulic cylinder.

[0040] In addition, in order to facilitate the observation of the test process of the Ferris wheel nylon wheel 40, preferably, the Ferris wheel nylon wheel bearing performance test device includes an observation unit for observing the Ferris wheel nylon wheel 40. The observation unit can be set to move synchronously with respect to the observed Ferris wheel nylon wheel 40, for example, the observation unit can include a camera installed on the walking mechanism 20. Among them, for different Ferris wheel nylon wheels 40, a camera for corresponding observation can be set. The observation unit can be set as a visual system and electrically connected to the control unit to be able to judge whether the Ferris wheel nylon wheel 40 is cracked and feedback a signal to the control unit when it is cracked, and the control unit can control the walking mechanism 20 and the testing mechanism 30 to stop accordingly. Of course, the camera can also transmit the shooting picture to the control platform for the operator to manually identify whether it is cracked. When the operator judges that the Ferris wheel nylon wheel 40 is cracked, the walking mechanism 20 and the testing mechanism 30 can be manually controlled to stop. It can be understood that when any camera observes that the corresponding Ferris wheel nylon wheel 40 is cracked, the current test is completed, and the control unit can control the walking mechanism 20 and the testing mechanism 30 to stop.

[0041] In addition, in order to facilitate test records and intuitively reflect the test situation, the Ferris wheel walking nylon wheel load-bearing performance test device includes a digital display unit for displaying the pressure applied by the test mechanism 30. The operator can adjust or stop the relevant parameters of the test (such as the speed of the walking mechanism 20, the pressure applied by the test mechanism 30, etc.) according to the display data of the digital display unit. The digital display unit can also be used to display the safety factor under the current loading pressure, that is, the ratio of the current applied pressure value (that is, the bearing pressure of the Ferris wheel walking nylon wheel 40) to the designed rated load.

[0042] In addition, to ensure that the running mechanism 20 carries the Ferris wheel nylon wheel 40 to move stably during the test, Figures 1 to 4 and Figure 7 As shown, the walking mechanism 20 may include a second pressing wheel 23 for pressing the track portion 10 from the lower side of the track portion 10. The second pressing wheel 23 can stably press the main body of the walking mechanism 20 on the track portion 10, and assist the first pressing wheel 32 in stabilizing the entire test device. A wheel frame 214 may be provided at the end of the transverse frame 212, and the Ferris wheel walking nylon wheel 40 and the second pressing wheel 23 may be installed through the wheel frame 214. For example, the Ferris wheel walking nylon wheel 40 may be installed on the shaft 50, and the shaft 50 is installed on the main body 21 through the wheel frame 214.

[0043] According to another aspect of the present application, a method for testing the load-bearing performance of a Ferris wheel nylon wheel is provided, wherein the method uses the testing device of the present application, and the method for testing the load-bearing performance of a Ferris wheel nylon wheel comprises: making the Ferris wheel nylon wheel 40 roll along the track portion 10, and at the same time applying pressure to the Ferris wheel nylon wheel 40 toward the track portion 10 through the testing mechanism 30, and gradually increasing the pressure until the Ferris wheel nylon wheel 40 meets the safety requirements or cracks to complete the test.

[0044] In the Ferris wheel running nylon wheel load-bearing performance testing method of the present application, pressure can be applied to the main body 21 through the testing mechanism 30, and then the pressure can be transmitted to the Ferris wheel running nylon wheel 40, so that the Ferris wheel running nylon wheel 40 rolls along the track portion 10 under pressure. The operation of the testing mechanism 30 can be controlled by the control unit, and the loading of the testing mechanism 30 can be controlled during the test until the Ferris wheel running nylon wheel 40 meets the safety requirements or cracks to complete the test.

[0045] During the test, the Ferris wheel nylon wheel 40 needs to be kept rolling along the track portion 10. Since the test process is long, the Ferris wheel nylon wheel 40 needs to be rolled along the track portion 10 for a long distance. In order to simplify the structure and save space, the walking mechanism 20 can be reciprocated along the track portion 10. Preferably, the control unit can be configured to control the walking mechanism 20 to reciprocate along the track portion 10.

[0046] In addition, during the test, it is necessary to increase the loaded pressure after the Ferris wheel nylon wheel 40 is loaded with a certain pressure and rolls normally for a predetermined time, so as to obtain the load-bearing pressure of the Ferris wheel nylon wheel 40 and obtain the safety factor accordingly. To this end, the method includes making the Ferris wheel nylon wheel reciprocate along the track portion and sequentially performing a normal pressure test and a boost test, wherein: during the normal pressure test, the pressure of the test mechanism is kept constant; during the boost test, the pressure of the test mechanism is gradually increased. In the normal pressure test, the test mechanism 30 can apply a normal load (i.e., a designed rated load) corresponding to the normal operation of the Ferris wheel. During the normal pressure test, the test mechanism 30 can be loaded with a normal load for a first preset time (e.g., 6h-8h). During the boost test, the loaded pressure can be gradually increased for testing. For example, during the step-by-step pressure test, each time the pressure is increased, the test time under the pressure can be a second preset time (e.g., more than 30 minutes). In addition, the pressure increase value of each test mechanism 30 can be the same or different, and can be specifically set according to the actual test situation.

[0047] The testing device and method of the present application are described below with reference to the accompanying drawings.

[0048] First, install the Ferris wheel nylon wheel 40 to the main body 21, and set the walking mechanism 20 on the track part 10, so that the Ferris wheel nylon wheel 40 contacts the walking track 12, the driving wheel 222 contacts the friction track 11, and the first clamping wheel 32 and the second clamping wheel 23 clamp the track part 10 from the bottom.

[0049] Then, the driving unit 22 can drive the traveling mechanism 20 to move so that the Ferris wheel traveling nylon wheel 40 rolls along the traveling track 12. At the same time, the testing mechanism 30 can be controlled to apply pressure to the main body 21, and whether the Ferris wheel traveling nylon wheel 40 is cracked can be observed in real time.

[0050] The test is divided into two stages, namely the normal pressure test stage and the boost test stage. The normal pressure test is first carried out, i.e., the test mechanism 30 is used to load the designed rated load for 6 hours. Then, the boost test is carried out, i.e., the pressure is gradually increased from the normal load through the test mechanism 30. Each time the pressure is increased, the pressure is loaded for 30 minutes at the pressure before the pressure is increased again.

[0051] During the pressure test, the control unit increases the loading pressure by controlling the proportional valve of the hydraulic cylinder of the test mechanism 30, so that the Ferris wheel nylon wheel 40 continues to move along the track 10 under the increased pressure. The above control is repeated until the safety requirements are met or the Ferris wheel nylon wheel 40 is observed to crack, and the travel mechanism 20 and the test mechanism 30 are controlled to stop.

[0052] During the test, the pressure value borne by the Ferris wheel walking nylon wheel 40 is recorded in real time, and the ratio of the pressure value to the design rated load of the Ferris wheel walking nylon wheel 40 is used as the safety factor, wherein: when the safety factor reaches 3.5 or more and the Ferris wheel walking nylon wheel 40 is not cracked, the test can be stopped and the Ferris wheel walking nylon wheel 40 passes the test; when the Ferris wheel walking nylon wheel 40 cracks and the safety factor does not reach 3.5, the test can be stopped and the Ferris wheel walking nylon wheel 40 fails the test.

[0053] The preferred embodiments of the present application are described in detail above; however, the present application is not limited to the specific details in the above embodiments. Within the technical concept of the present application, a variety of simple modifications can be made to the technical solution of the present application, and these simple modifications all fall within the protection scope of the present application.

[0054] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this application will not further describe various possible combinations.

[0055] In addition, the various implementation modes of the present application may be arbitrarily combined, and as long as they do not violate the concept of the present application, they should also be regarded as the contents disclosed in the present application.
