Description

TECHNICAL FIELD

[0001] The utility model relates to test frock technical field especially relates to a test frock of apron drive arrangement. BACKGROUND

[0002] It is very common to carry out operation and transportation under high altitude environment, especially in the field of wind power generation, personnel and material transportation and maintenance are carried out between high altitude operation platform and ground by using lifting equipment.

[0003] When the lifting equipment needs to pass through the corresponding tower drum platform, the platform cover plate on the corresponding tower drum platform is automatically opened to avoid, so that the lifting equipment freely passes through the tower drum platform. When the lifting equipment leaves the tower drum platform, the platform cover plate on the corresponding tower drum platform is automatically closed and used as a bearing element to improve the safety of the operation environment.

[0004] Because the platform cover plate needs to be used as a bearing element, the weight of the platform cover plate is large, generally between 15KG and 25KG. Therefore, the cover plate driving device equipped with the platform cover plate needs sufficient driving force to meet the requirements of automatic opening and closing of the platform cover plate. Because the installation space of the cover plate driving device is small and the design is compact, the volume of the selected driving motor is correspondingly small. In the assembly process, the driving force of the cover plate driving device is insufficient due to assembly error and other factors. In the application process, the cover plate driving device cannot normally open and close the platform cover plate. At present, the factory detection of the cover plate driving device is only to measure the output torque of the driving motor, which cannot simulate the actual use condition to effectively detect the driving force, and the cover plate driving device with quality problems is easy to flow to the market.

[0066] Accordingly, in order to be more compact in structure, a part of swing drive part 32 is installed on the upper portion of test platform 10, and another part of swing drive part 32 is installed on the lower portion of test platform 10. Linear drive part 33 is connected to swing drive part 32, and linear drive part 33 is embedded in test platform 10.

[0080] When the linear driving part 332 (i.e. a linear motor) controls the rotation of the lead screw 333, the sliding block 334 is limited by the guide part 335, and the rotary motion of the lead screw 333 is converted into linear reciprocating motion, thereby driving the pulley part 31 arranged thereon to perform linear reciprocating motion.

[0081] A guide groove 3311 can also be formed on both sides of the bearing body 331. The guide groove 3311 is arranged along the extension direction of the lead screw 333. The sliding block 334 is clamped in the guide groove 3311 and moves along the extension direction of the guide groove 3311.

[0098] Correspondingly, one end of the traction rope 24 is fixedly connected with the free end of the test swing arm 22, the other end of the traction rope 24 sequentially passes through the fixed pulley 311 and the V-shaped groove of the first guide wheel 62 and the second guide wheel 63 on the test platform 10 and is connected with the counterweight 23.

[0099] The test tool of the cover plate driving device provided by the embodiment of the utility model can detect the driving force of the cover plate driving device 70 according to the working state and load of the platform cover by simulating the actual use condition of the cover plate driving device 70, and the resistance of the test swing arm 22 is kept constant during the detection process, so that whether the cover plate driving device 70 to be shipped out conforms to the design of the target opening force can be determined, and the test efficiency can be improved.

[0100] Figure 9 is one of the test schematic diagrams of the test tool provided by the embodiment of the utility model (the test swing arm is located at an initial position). Figure 10 is the second test schematic diagram of the test tool provided by the embodiment of the utility model (the test swing arm is located at an intermediate position). Figure 11 is the third test schematic diagram of the test tool provided by the embodiment of the utility model (the test swing arm is located at an end position).

[0101] Referring to Figures 9 to 11 , each figure shows the test process of the key position of the test tool simulating the opening of the platform cover to test the driving force (opening force) of the cover plate driving device 70:

[0102] In the installation process, in order to ensure the stability of the cover plate driving device 70 during the test and facilitate the installation of the cover plate driving device 70, the front end of the cover plate driving device 70 is limited by the mounting plate 25, and the two sides of the cover plate driving device 70 are limited by the positioning plate 131. The cover plate driving device 70 can be inserted into the limiting slot limited by the positioning plate 131 and the table top 11 of the test platform 10 from the end of the positioning plate 131 away from the mounting plate 25, and the output shaft of the cover plate driving device 70 is synchronously inserted into the key groove hole of the rotating shaft of the test swing arm 22, so that the test swing arm 22 is directly connected with the output shaft of the cover plate driving device 70.

[0103] In the initial position, the test swing arm 22 is rotated to the horizontal position, the controller collects the angular displacement of the test swing arm 22 through the first angular displacement sensor 40, and controls the swing driving part 32 to rotate the same angular displacement, so that the linear driving part 33 is rotated to the horizontal position and keeps parallel with the test swing arm 22. The pulley part 31 installed on the linear driving part 33 retreats to the initial position. At this time, the traction rope 24 naturally hangs down, and the gravity generated by the counterweight 23 is applied to the test swing arm 22 through the traction rope 24, so that the force direction of the test swing arm 22 is perpendicular to the axis direction of the test swing arm 22, and the resistance value of the test swing arm 22 is the gravity of the counterweight 23.

[0104] In the intermediate position, the test swing arm 22 in the test assembly 20 is rotated from 0° to 90° with the test platform 10, at this time, the controller collects the angular displacement of the test swing arm 22 through the first angular displacement sensor 40, and controls the swing driving part 32 to rotate the same angular displacement, so that the linear driving part 33 keeps parallel with the test swing arm 22 in the test assembly 20. The pulley part 31 installed on the linear driving part 33 moves to the front end according to the set speed, so that the traction rope 24 keeps perpendicular to the test swing arm 22 in the test assembly 20; since the friction between the pulley part 31 and the traction rope 24 can be ignored, therefore, the force direction of the test swing arm 22 in the test assembly 20 is perpendicular to the axis direction of the test swing arm 22, and the resistance value of the test swing arm 22 is the gravity of the counterweight 23.

[0105] In the end position, the test swing arm 22 in the test assembly 20 is 90° with the test platform 10, at this time, the linear driving part 33 keeps parallel with the test swing arm 22 in the test assembly 20. The pulley part 31 installed on the linear driving part 33 moves to the end according to the set speed, so that the traction rope 24 keeps perpendicular to the test swing arm 22 in the test assembly 20; since the friction between the pulley part 31 and the traction rope 24 can be ignored, therefore, the force direction of the test swing arm 22 in the test assembly 20 is perpendicular to the axis direction of the test swing arm 22, and the resistance value of the test swing arm 22 is the gravity of the counterweight 23.

[0106] Therefore, no matter in the initial position or in the end position, the test swing arm 22 is always subjected to the pulling force of the counterweight 23, and the resistance arm of the test swing arm 22 remains unchanged, so that the test tool of the cover plate driving device 70 forms a constant resistance.

[0107] The test tool of the cover plate driving device provided in the embodiment of the present application maintains the constant maximum resistance in the whole test process, of course, various variable resistance tests can also be simulated by using the angle change, and a hardware platform meeting the test is provided for various complex working conditions.
