[0066] Example 1
[0067] The size of this test device is scaled up in equal proportion to obtain the actual hoisting platform. The specific ratio is the size of this test device: the size of the actual hoisting platform = 1:11.
[0068] This test device drives the load-bearing plate 4 with the hoisting module to move horizontally and vertically through the horizontal movement motor 11 and the vertical movement motor 19 in order to simulate the hoisting movement process of the actual hoisting platform. This test device can conduct anti-sway control tests for the hoisting platform, real-time automatic leveling control tests for the hoisting platform, self-disturbance rejection stability improvement tests for the hoisting platform, and image recognition and positioning tests.
[0069] Image recognition and positioning test:
[0070] By installing a camera and a laser range finder sensor on the load-bearing plate 4, the camera and the laser range finder sensor are electrically connected to the upper computer. The laser range finder sensor is used to sense the position of the load-bearing plate 4 and thus sense the position of the module to be hoisted. The camera captures the image information of the module to be hoisted and transmits it to the upper computer, so that the upper computer can perform image recognition and positioning on the module to be hoisted below the load-bearing plate 4 and determine the position where the module to be hoisted is located.
[0071] Anti-sway control test for the hoisting platform:
[0072] The horizontal movement motor 11 and the vertical movement motor 13 drive the load-bearing plate 4 to drive the module to be hoisted to move. The first laser sensor 45 is used to measure the longitudinal movement displacement of the load-bearing plate 4, and the second laser range finder sensor 44 is used to measure the horizontal movement displacement of the load-bearing plate 4. While the hoisting module is moving, the first lifting motor 42 and the second lifting motor 46 lift the module to be hoisted. During the lifting process, the module to be hoisted swings, and the first wire rope 31 swings accordingly and touches the first swing angle measurement piece group 482 and the second swing angle measurement piece group 492. The first rotary encoder 481 and the second rotary encoder 491 measure the swing angles of the first wire rope 31 in two directions to obtain the swing angle of the module to be hoisted. Appropriate power equipment is replaced according to the swing angle to ensure a better lifting effect.
[0073] Real-time automatic leveling control test for the hoisting platform:
[0074] Install the module to be hoisted under the metal rod 52 of the leveling mechanism 5; the upper computer controls the telescoping of the electric cylinder 51 connected to the inclined metal rod 52 according to the data of the inclination sensor 53 to keep the metal rod 52 and the module to be hoisted horizontal.
[0075] Self-disturbance rejection stability improvement test for the hoisting platform:
[0076] The host computer controls the synchronous start of the first lifting motor 42 and the second lifting motor 46. While driving the module to be lifted upward, the first winding drum 43 rotates to keep the first steel wire rope 31 taut. By using auxiliary tools such as a fan to create external interference, the module to be lifted will swing and tilt under the interference. The first rotary encoder 481 and the second rotary encoder 491 measure the swing angles of the first steel wire rope 31 in two directions and feed the data back to the host computer. The inclination sensor 53 measures the deflection data of the metal rod 52. The host computer controls the telescoping of the electric cylinder 51 connected to the deflected metal rod 52 according to the deflection data, so that the metal rod 52 and the module to be lifted are kept horizontal. The host computer judges the stability of the lifting platform during lifting according to the measurement data of the first rotary encoder 481, the second rotary encoder 491 and the inclination sensor 53.
[0077] The structure of this solution is simple and easy to use. Using the host computer to control the horizontal and vertical adjustment mechanism can accurately determine the position of the lifting module, reduce labor costs, save time, and reduce potential safety hazards. Moreover, this solution sets the first steel wire rope in cooperation with the first winding drum to perform rigid-flexible conversion on the lifting of the lifting module, so that the first steel wire rope has tension and is always in a taut state during the lifting process, reducing the swing of the lifting module. This solution sets the swing angle measurement component to accurately measure the swing angle of the lifting module and feed it back to the host computer. According to the data of the host computer, the power equipment and control system of this device can be iteratively adjusted to make the lifting module more matched with the power equipment of this device and improve the lifting effect. This solution designs a leveling mechanism to keep the lifting module in a horizontal state all the time, ensuring the lifting stability. This solution designs the use of crossed roller bearings combined with motors for lifting, which can prevent the lifting ropes from winding, ensure good lifting effects, and reduce potential safety hazards.
[0078] This device can conduct simulation experiments on the actual lifting situation, and can conduct anti-sway control tests of the lifting platform, real-time automatic leveling control tests of the lifting platform, and self-disturbance rejection stability improvement tests of the lifting platform. Applying the experimental results to the actual scenario can greatly improve the lifting efficiency.
