Description

Technical Field

[0001] This invention relates to the field of crane testing technology, specifically to a testing platform for testing the wind and slip resistance of cranes. Background Technology

[0002] Cranes are heavy-duty engineering machines used for vertical lifting and horizontal transport of heavy objects. They are widely used in construction, port loading and unloading, mining, power construction, and many other fields. Their core function is to achieve precise displacement of heavy objects in a specific space through the coordinated work of the hoisting mechanism, traveling mechanism, luffing mechanism, and slewing mechanism. As a key piece of equipment in engineering construction, the safety and stability of cranes are directly related to construction safety and project progress. Different types of cranes can be adapted to different operating environments and load requirements. Crane wind resistance and anti-slip testing is a key testing link to ensure the safe operation of cranes in outdoor operating environments. Due to the complex and variable operating environment of cranes, they are easily affected by natural wind forces when operating outdoors, especially in open areas, high-altitude operations, or coastal areas. Strong winds may cause horizontal displacement, swaying, or even complete overturning of cranes, leading to serious safety accidents. Therefore, this test can accurately verify the reliability of the crane's windproof device and the stability of the crane's overall structure under wind load, providing a scientific basis for setting safe operating parameters and optimizing windproof measures for cranes, fundamentally avoiding safety risks caused by wind loads, and ensuring the safety of personnel and equipment.

[0003] In the existing technical field, crane wind and skid resistance testing technologies generally suffer from problems such as limited testing scenarios and insufficient simulation accuracy. They are difficult to accurately replicate the impact of actual complex working conditions on test results. In terms of road surface simulation, it is impossible to flexibly switch between test surfaces with different roughness and smoothness. Most tests can only be carried out on a single fixed road surface, resulting in test results that cannot fully reflect the anti-skid performance of cranes under different actual road conditions such as mud, ice, and gravel. In terms of wind resistance testing, the adjustment range of wind direction and intensity is limited and the accuracy is low, making it difficult to simulate the dynamic effects of different levels of natural wind. At the same time, the wind force is fixed in position during the test, making it impossible to achieve comprehensive testing of wind loads from multiple directions. Therefore, it is impossible to meet the need for a comprehensive and accurate assessment of the wind and skid resistance of cranes. Summary of the Invention

[0013] Preferably, when pre-setting the fixed steel plates before the test, multiple steel plates with different roughness are placed inside the front and rear frames, with the rough surfaces of the steel plates facing the front and rear sides of the column shell and the smooth surfaces facing the front and rear fixed bases. The controller starts four sets of fourth electric telescopic rods, which extend and push the fixed claws to rotate inward around the connection point with the frame. The two sets of fixed claws engage the four outer corners of the steel plates, firmly clamping the steel plates inside the fixed bases.

[0014] Preferably, the storage mechanism further includes: limiting components, clamping seats, and a fifth electric telescopic rod; the number of limiting components is two sets, with two limiting components in each set, and the two sets of limiting components are respectively installed on the upper and lower sides of the left front and rear ends of the cross frame; the number of clamping seats is two, and the two clamping seats are respectively installed on the outer side of the limiting ends of the front and rear sets of limiting components; the number of fixed bases is two, and the two fifth electric telescopic rods are respectively installed on the front and rear ends of the right side of the cross frame, with the telescopic ends of the two fifth electric telescopic rods respectively fixedly connected to the inner side of the front and rear clamping seats, and the fifth electric telescopic rods are electrically connected to the controller.

[0015] Preferably, when switching road conditions, the controller triggers the storage mechanism to rotate the platform, causing the column housing to rotate, so that the scissor telescopic mechanism and the crossbeam are aligned with the target steel plate. The scissor telescopic mechanism extends and pushes the crossbeam closer to the steel plate. The fifth electric telescopic rod shortens and drives the clamping seat to clamp the left and right sides of the steel plate under the guidance of the limiting component. The fourth electric telescopic rod extends and drives the fixing claw to release the fixation. The scissor telescopic mechanism retracts and the rotating platform resets, so that the smooth surface of the steel plate faces the installation mechanism.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The rotating platform drives the column housing to rotate, which, in conjunction with the column housing, drives the scissor telescopic machine to rotate the crossbeam to the inner side of the fixed base at the corresponding position. The scissor telescopic machine extends itself to drive the crossbeam to move outward, so that the crossbeam is close to the steel plate. The fifth electric telescopic rods on both sides shorten and drive the clamping seats at the corresponding positions, so that the clamping seats move inward under the limiting action of the upper limit component at the corresponding positions. The clamping seats on both sides clamp and fix the left and right sides of the steel plate. At the same time, the fourth electric telescopic rods on all four sides extend and drive the fixed claws at the corresponding positions to rotate outward, releasing the fixation of the steel plate and completing the transfer operation. The scissor telescopic machine and the rotating platform are reset in sequence to drive the steel plate to rotate and make the smooth surface of the steel plate face the installation mechanism's transport station.

[0018] 2. The second electric telescopic rod drives the rotating frame at the corresponding position, causing the rotating frame to rotate upward around the axis connecting to the inner side of the vertical tank shell. Under the limiting action of the lower rotating frame, the front and rear rotating frames drive the front and rear tank shells to move upward to the specified height. The first motor drives the bridge plate to rotate upward inside the tank shell, causing the bridge plate to rotate from horizontal to vertical, so that the rough surface of the inner steel plate of the bridge plate faces upward. The second motor drives the bracket to rotate counterclockwise until it contacts the top of the base frame, so that the bracket rotates downward from vertical to horizontal. The third electric telescopic rods on the front and rear sides extend, driving the bottom end of the second connecting rod at the corresponding position to move to the left, so that the other end of the second connecting rod drives the left rotating shaft to rotate clockwise. The left rotating shaft drives the triangular frames on its front and rear sides to rotate clockwise upward. Under the transmission connection of the first connecting rod at the corresponding position, the two triangular frames on the left rotate on the right. Under the action of the shaft, the system rotates synchronously clockwise upwards. The two sets of triangular frames on the left and right drive the base plate frame to move upwards, which in turn drives the four side buffer pads to move upwards and support them after contacting the lower surface of the inner steel plate of the bracket. The second electric telescopic rod and the first motor reset, driving the bridge plate to move horizontally to the upper left of the upper surface of the steel plate, so that the left and right ends of the bridge plate form a channel with the surface of the steel plate. The staff moves the crane to be tested along the bridge plate to the surface of the steel plate. The mobile robot moves to the designated position outside the crane to be tested according to the preset route. The preset program inside the mobile robot controls the electric support feet, electric adjustment base and fan to start. The electric support feet contact the ground to provide auxiliary support and prevent displacement after the fan starts. The electric adjustment base adjusts the height and direction of the fan. The fan generates high-pressure wind force to blow to the outside of the crane, thereby simulating the crane's windproof and anti-slip capabilities under different directions and wind forces, as well as on road conditions with different smoothness and flatness.

[0019] In summary, this invention enables diversified and accurate simulation of test scenarios and automated collaborative testing processes. At the road surface simulation level, it can flexibly construct test road environments with varying roughness and smoothness, and quickly switch test carriers according to testing needs, achieving accurate replication of various complex real-world road conditions. This allows the test results to truly reflect the anti-skid performance of cranes under different road surface conditions. At the wind resistance testing level, it allows for precise adjustment and flexible switching of wind intensity and direction, simulating the dynamic effects of different levels of natural wind. Furthermore, it enables comprehensive testing of multi-directional wind loads through movement and adjustment, comprehensively evaluating the wind resistance performance of cranes under complex wind load environments, and providing strong technical support for a comprehensive and accurate evaluation of the wind resistance and anti-skid capabilities of cranes.

They can extend synchronously and make close contact with the ground after the mobile robot 41 moves to the designated position, forming a stable auxiliary force. The supporting structure counteracts the wind reaction force generated by the subsequent start-up of the fan 44, preventing displacement or swaying of the mobile robot 41 and ensuring the stability and accuracy of the wind simulation. The electrically adjustable base 43 is fixedly installed on the rear side of the outer surface of the mobile robot 41. The electrically adjustable base 43 and the mobile robot 41 are electrically connected. The electrically adjustable base 43 is a multi-degree-of-freedom electrically adjustable base, capable of precisely adjusting the installation height, horizontal direction, and pitch angle of the fan 44. According to the requirements of the test plan, the airflow direction of the fan 44 can be precisely aligned with different parts of the crane to achieve different... Simulation of wind direction: Fan 44 is installed on the top of the moving end of the electric adjustment base 43. Fan 44 is electrically connected to the mobile robot 41. Fan 44 is an industrial-grade high-pressure axial flow fan. The wind speed adjustment signal of fan 44 is transmitted to controller 1 through mobile robot 41. Fan 44 is equipped with a soundproof cover and protective net, which can generate high-pressure wind of different intensities. The wind is blown out of the crane through the direction adjusted by electric adjustment base 43, accurately simulating the different wind environments that the crane may encounter in actual working conditions, and providing standard wind load conditions for wind resistance and anti-slip capability testing.

[0033] As a preferred option, further, such as Figure 6 and Figure 7As shown, the storage mechanism 5 includes: a fixed base 51, a frame 52, fixed claws 53, a fourth electric telescopic rod 54, a rotating platform 55, a column housing 56, a scissor telescopic mechanism 57, a crossbar 58, a limiting component 59, a clamping seat 510, and a fifth electric telescopic rod 511; there are two fixed bases 51, which are fixedly installed on the lower right side and the front and rear sides of the installation mechanism 2 in the vertical direction; there are two frames 52, which are installed on the inner upper sides of the front and rear fixed bases 51; there are two sets of fixed claws 53, with four claws in each set, and the two sets of fixed claws 53 are fixedly installed on the front and rear sides of the installation mechanism 2. Fixed claws 53 are rotatably mounted at the four outer corners of the front and rear frames 52 via rotating shafts. The fixed claws 53 are customized anti-slip claws, capable of rotating inwards under the drive of the fourth electric telescopic rod 54 to clamp and fix the four outer corners of the steel plates stored within the frame 52. There are two sets of the fourth electric telescopic rods 54, each set containing four rods. The two sets of fourth electric telescopic rods 54 are rotatably mounted at the four outer corners of the front and rear frames 52 via rotating shaft seats. The telescopic ends of the two sets of fourth electric telescopic rods 54 are rotatably connected to the inner and outer ends of the two sets of fixed claws 53 via rotating shaft seats. Rod 54 is electrically connected to controller 1. The fourth electric telescopic rod 54 is a small, high-precision electric telescopic rod that provides rotational driving force for the fixing claw 53. Through telescopic movement, it drives the fixing claw 53 to switch between clamping and releasing actions, completing the storage, fixing, and release preparation before the transfer of the steel plate. The rotating platform 55 is fixedly installed on the inner ground of the front and rear fixed bases 51. The rotating platform 55 is electrically connected to controller 1. The rotating platform 55 is a high-precision electric rotating platform driven by a servo motor, supporting continuous rotation and fixed-point positioning. It can drive the rotation of the top column housing 56 to achieve precise switching of the plate picking direction. The steel plates can be aligned with different storage locations according to the test requirements to ensure the accuracy of steel plate switching; the column housing 56 is fixedly installed on the top of the rotating end of the rotating platform 55 in the vertical direction; the scissor telescopic machine 57 is fixedly installed on the left side of the outer surface of the column housing 56. The scissor telescopic machine 57 is electrically connected to the controller 1. The scissor telescopic machine 57 is an electric scissor lifting telescopic platform, which can drive the cross frame 58 to achieve horizontal telescopic movement, adjust the distance between the clamping component and the stored steel plate, and complete the position adjustment during the gripping, docking and transfer of the steel plate; the cross frame 58 is fixedly installed on the middle left side of the telescopic end of the scissor telescopic machine 57 in the front-back direction.There are two sets of limiting components 59, with two components in each set. The two sets of limiting components 59 are respectively installed on the left front and rear ends and the upper and lower sides of the crossbeam 58. The limiting components 59 are customized linear guide rail limiting components, with the guide rails bolted to the left front and rear ends and the upper and lower sides of the crossbeam 58. The slider is fixedly connected to the clamping seat 510, providing precise guidance for the movement of the clamping seat 510, restricting its movement to the horizontal direction, preventing offset or shaking during clamping, and ensuring the accuracy and stability of the clamping seat 510 in clamping the steel plate. There are two clamping seats 510. Clamping seats 510 are respectively installed on the outer side of the limiting ends of the front and rear sets of limiting components 59; there are two fixed bases 51, and two fifth electric telescopic rods 511 are respectively installed at the front and rear ends of the right side of the cross frame 58. The telescopic ends of the two fifth electric telescopic rods 511 are respectively fixedly connected to the inner side of the front and rear clamping seats 510. The fifth electric telescopic rods 511 are electrically connected to the controller 1. The fifth electric telescopic rods 511 are high-precision electric telescopic rods, which can provide horizontal movement driving force for the clamping seats 510. Through the telescopic action, the clamping seats 510 are driven to move precisely along the limiting components 59 to realize the clamping or releasing action of the steel plate.

[0034] The specific work steps are as follows:

[0035] Step 1: Before the test, the staff placed several steel plates with different roughnesses one by one into the inner area of ​​the front and rear frames 52 of the storage mechanism 5. When placing them, the orientation must be strictly observed to ensure that the rough surface of the steel plate (the core surface used to simulate different road conditions) faces the front and rear sides of the column shell 56, and the smooth surface faces the front and rear fixed bases 51 on the outside (used for the adsorption and transportation surface of the subsequent installation mechanism 2). After the arrangement is completed, the staff issued a command through the controller 1 to start the four sets of fourth electric telescopic rods 54 on the outside of the frame 52. The four sets of fourth electric telescopic rods 54 on the four sides extended synchronously. Their telescopic ends would generate a pushing force on the outer end of the fixed claws 53 at the corresponding positions, forcing the fixed claws 53 to rotate inward with the pivot at the connection with the frame 52 as the axis. The two sets of fixed claws 53 were precisely engaged at the four outer corners of the steel plate, firmly clamping the steel plate in the inner position of the fixed base 51, thus completing the pre-fixing of the test steel plate.

[0036] Step 2: When the test requires simulating road conditions with different roughness, the controller 1 automatically triggers the action of the storage mechanism 5 through the internal preset program, controlling the rotating platform 55, the scissor telescopic mechanism 57, and the fifth electric telescopic pole 511 to start. The rotating platform 55 drives the top column housing 56 to rotate clockwise or counterclockwise. Through the linkage of the column housing 56, it drives the scissor telescopic mechanism 57 and the crossbeam 58 on its left side to rotate to the inside of the fixed base 51 where the target steel plate is located, realizing the alignment of the plate picking direction. The scissor telescopic mechanism 57 extends, pushing the crossbeam 58 to move towards the steel plate until the plate is picked up. The clamping seats 510 on both sides approach the steel plate, and the fifth electric telescopic rods 511 at both ends of the crossbeam 58 shorten synchronously, driving the corresponding clamping seats 510 to move inward under the guidance and limiting action of the limiting component 59. The two clamping seats 510 clamp the middle of the left and right sides of the steel plate, completing the clamping and gripping of the steel plate. The fourth electric telescopic rods 54 on the four sides that were originally fixing the steel plate extend synchronously, driving the fixing claws 53 to rotate outward, releasing the initial fixation of the steel plate. The scissor telescopic machine 57 retracts, the rotating platform 55 resets, and drives the steel plate to rotate and adjust its orientation, so that the smooth surface of the steel plate faces the handling station of the installation mechanism 2.

[0037] Step 3: After the steel plate is selected, the controller 1's preset program starts the dual-moving end rails 21, the first linear moving module 23, the second linear moving module 24, the first electric telescopic rod 27, and the electric suction cup frame 28. The two dual-moving end rails 21 start, driving the upper gantry 22 to move towards the storage mechanism 5 on the right until the conveying structure below the gantry 22 is aligned with the plate-retrieving position on the left side of the storage mechanism 5. The first linear moving module 23 starts, driving the second linear moving module 24 at its bottom to move horizontally to the right, completing the first level of horizontal fine-tuning. Then, the second linear moving module 24 drives the slot frame 25 at its bottom to move further to the right, completing the second level of horizontal fine-tuning. Through two levels of linear movement, the precise alignment of the electric suction cup frame 28 is ensured. The four sets of first electric telescopic rods 27 at the four corners of the outer side of the slot frame 25 extend and retract synchronously, driving the lifting frame 26 on the inner side of the slot frame 25 to rise and fall vertically to the specified height, thereby driving the lifting... The electric suction cup frame 28 inside the lowering frame 26 is adjusted to a height flush with the smooth surface of the steel plate. When the electric suction cup frame 28 moves and adheres to the smooth surface of the steel plate, the electric suction cup frame 28 starts to generate negative pressure to adsorb the steel plate. At the same time, the fifth electric telescopic rod 511 holding the steel plate extends synchronously, driving the clamping seat 510 to move outward, releasing the clamp on the steel plate, and completing the connection of the installation mechanism 2 to the steel plate. With the double moving end ground rail 21 driving the gantry frame 22 to move to the left side of the road simulation mechanism 3, the first linear moving module 23 and the second linear moving module 24 cooperate to drive the slot frame 25 and the adsorbed steel plate to move to the left until the steel plate passes through the inside of the U-shaped bracket 39 of the road simulation mechanism 3, and the front and rear ends and bottom of the steel plate are engaged and positioned with the U-shaped structure of the bracket 39. At this time, the electric suction cup frame 28 stops the negative pressure adsorption, releases the fixation of the steel plate, and completes the transfer of the steel plate to the road simulation mechanism 3. The steel plate is temporarily supported by the bracket 39.

[0038] Step 4: After the steel plate is in place, controller 1 activates the second electric telescopic rod 34, the first motor 37, the second motor 310, and the third electric telescopic rod 312. The second electric telescopic rod 34 retracts, generating tension on the corresponding rotating frame 33, causing the rotating frame 33 to rotate upwards around the axis of connection with the vertical tank shell 32. Under the limiting support of the lower rotating frame 33, the front and rear sets of rotating frames 33 synchronously drive the tank shell 35 on both sides to move upwards to the designated height. The first motor 37 starts, driving the bridge plate 36 on the inner side of the tank shell 35 to rotate upwards, changing the bridge plate 36 from a horizontal state to a vertical state, thus providing space for the subsequent rotation of the bracket 39. The second motor 310 starts, driving the U-shaped bracket 39 supporting the steel plate to rotate counterclockwise until the bracket 39 contacts the top of the base frame 38. The bracket 39 changes from a vertical state to a horizontal state, and the steel plate is then placed stably. The third electric telescopic rods 312 on both sides extend synchronously, pushing the corresponding position... The bottom end of the second connecting rod 316 moves to the left, thereby driving the left rotating shaft 313 at the other end of the second connecting rod 316 to rotate clockwise. The left rotating shaft 313 drives the triangular frames 314 on its front and rear sides to rotate clockwise upward. The left triangular frame 314, through the transmission of the first connecting rod 315, drives the right rotating shaft 313 and the right triangular frame 314 to rotate clockwise upward synchronously. The two sets of triangular frames 314 work together to push the bottom plate frame 317 at the top to move upward. The bottom plate frame 317 drives the buffer pads 318 at the four corners to move upward until the buffer pads 318 are in close contact with the lower surface of the steel plate, forming a stable support for the steel plate. The second electric telescopic rod 34 and the first motor 37 reset, driving the bridge plate 36 to rotate back to the horizontal state and move to the upper left of the upper surface of the steel plate, so that the left and right ends of the bridge plate 36 form a continuous passageway with the surface of the steel plate. The staff operates the crane to be tested, travels along the bridge plate 36 to the rough surface of the steel plate, and completes the test positioning of the crane.

[0039] Step 5: After the crane is in place, the internal structure of the installation mechanism 2 is reset sequentially to avoid interfering with the test process. The pre-set program inside the controller 1 controls the start of the mobile robot 41. The mobile robot 41 moves along the designated route according to the different wind force angle positions set according to the test requirements. After reaching the position, the internal program of the mobile robot 41 activates the electric support foot 42, the electric adjusting base 43 and the fan 44. The electric support foot 42 extends downward and makes close contact with the ground to form a stable auxiliary support, preventing the mobile robot 41 from shifting due to the wind force generated by the subsequent start of the fan 44. The electric adjusting base 43 adjusts the height and air outlet angle of the fan 44 according to the wind force height and direction set in the test. After the fan 44 is started, it generates high-pressure wind force, which is blown to the outside of the crane according to the set parameters. Through the above actions, the working environment of the crane under different wind intensities, different wind directions and different road surface smoothness and flatness conditions can be simulated, thereby completing the wind resistance and anti-slip capability test of the crane.
