[0034] Currently, for operations such as flaw detection, rust removal, and welding of large steel structures such as large ships, petrochemical storage tanks, and wind turbine towers, intelligent operation equipment has begun to be used to replace manual labor for automated operations. A common automated device among them is the wall-climbing robot 300. The wall-climbing robot 300 is usually wheeled or tracked, and the obstacle-crossing height generally does not exceed 15 mm. For accessories such as the wind-resistant ring 200 or the fire pipe on the tank wall, it cannot cross.

[0035] For this, please refer to Figures 1 - 4 , the solution of this application provides a lifting platform, which includes a lifting mechanism 10, a suspension platform 20, an adsorption mechanism 30, and a hoisting mechanism 40.

[0036] Please refer to Figure 1 and Figure 2 , the lifting mechanism 10 drives the suspension platform 20 to lift. The suspension platform 20 is used to provide a working area for the operator.

[0037] The adsorption mechanism 30 is arranged on the suspension platform 20 to lift along with the suspension platform 20. The adsorption mechanism 30 has an adsorption function, and the adsorption mechanism 30 can adsorb and fix on a wall surface 100 that is vertical or inclined relative to the ground. For example, on the wall surfaces 100 of large ships, petrochemical storage tanks, and wind turbine towers.

[0038] The hoisting mechanism 40 is arranged on the suspension platform 20 to lift and lower along with the suspension platform 20. The hoisting mechanism 40 is used to hoist the wall-climbing robot 300. Here, the wall-climbing robot 300 refers to a robot that can climb on a wall surface 100 that is vertical or inclined relative to the ground. The wall-climbing robot 300 can have various functions, such as flaw detection function, rust removal function, and welding function.

[0039] When it is necessary to adjust the working area of the wall-climbing robot 300, the operator enters the suspension platform 20, and the lifting mechanism 10 drives the suspension platform 20 to rise to the position where the wall-climbing robot 300 is located. The adsorption mechanism 30 adsorbs and fixes on the wall surface 100, making the entire suspension platform 20 remain stable relative to the wall surface 100. The hoisting mechanism 40 connects to the wall-climbing robot 300, disconnecting the wall-climbing robot 300 from the wall surface 100. The hoisting mechanism 40 lowers the wall-climbing robot 300 to the suspension platform 20. The adsorption mechanism 30 releases the adsorption, separating the suspension platform 20 from the wall surface 100. The suspension platform 20 is lifted and lowered to cross the obstacle to the next working area. The adsorption mechanism 30 adsorbs and fixes on the wall surface 100 again, making the entire suspension platform 20 remain stable relative to the wall surface 100. The hoisting mechanism 40 raises the wall-climbing robot 300, connects the wall-climbing robot 300 to the wall surface 100, and then disconnects the hoisting mechanism 40 from the wall-climbing robot 300, thus enabling the wall-climbing robot 300 to cross the obstacle. Compared with the prior art, the above-mentioned lifting platform can quickly and safely assist the wall-climbing robot 300 to cross the obstacle, improving the working efficiency of the wall-climbing robot 300.

[0040] It can be understood that during the lifting and lowering process of the suspension platform 20, it is necessary to cross obstacles. As the part connected to the wall surface 100, the adsorption mechanism 30 is likely to collide with the obstacles during the lifting and lowering process.

[0041] In some embodiments, the adsorption mechanism 30 includes a telescopic driving member 31 and a suction cup 32. The telescopic driving member 31 is arranged on the lifting platform. The telescopic driving member 31 has a telescopic rod 311 that can be telescoped. The suction cup 32 is arranged on the telescopic rod 311. The telescopic rod 311 of the telescopic driving member 31 can extend outwards to drive the suction cup 32 to adsorb on the wall surface 100, or retract inwards to drive the suction cup 32 to disengage from the wall surface 100.

[0042] The telescopic driving member 31 includes a linear driving member, and the structure of the linear driving member is not limited. For example, it can be a linear motor. In some embodiments, the telescopic driving member 31 is a cylinder, and the telescopic rod 311 is the piston rod of the cylinder.

[0043] The structure of the suction cup 32 is not limited. For example, the suction cup 32 can be a negative pressure suction cup 32, which is fixed on the wall surface 100 by negative pressure adsorption. In some embodiments, the suction cup 32 is a magnetic suction cup 32, which is fixed on the steel wall surface 100 of large ships, petrochemical storage tanks, and wind turbine towers by magnetic attraction.

[0044] It can be understood that the telescopic rod 311 of the telescopic driving member 31 can extend outwards to drive the suction cup 32 to adsorb on the wall surface 100, or retract inwards to drive the suction cup 32 to disengage from the wall surface 100. In this way, when the lifting and suspension platform 20 crosses an obstacle, the suction cup 32 is in the retracted state and away from the wall surface 100, thus avoiding interference with the obstacle.

[0045] Please refer to Figure 2 and Figure 3 , in some embodiments, the telescopic driving member 31 has a mounting base 312, the mounting base 312 is arranged at one end of the telescopic rod 311, and the suction cup 32 is pivotally connected to the mounting base 312. It can be understood that by deflecting the suction cup 32, it can always be directly opposite and adsorbed on the wall surface 100 in the scenarios of an arc-shaped wall surface 100 or a conical wall surface 100, thereby improving the adsorption stability.

[0046] In some embodiments, the telescopic driving member 31 has a hinge shaft, the suction cup 32 and the mounting base 312 are hinged through the hinge shaft, and the axial direction of the hinge shaft is parallel to the lifting direction of the lifting mechanism 10. It can be understood that the hinge shaft can transmit loads, has better connection stability, and can adapt to the arc-shaped wall surface 100, so as to adapt to scenarios such as storage tanks.

[0047] The specific structure of the hinge connection between the suction cup 32 and the mounting base 312 through the hinge shaft is not limited. In some embodiments, the mounting base 312 has protruding connection ears 3121 on the surface facing the suction cup 32. The number of the connection ears 3121 is two. Hinge holes are formed on the connection ears 3121. At least part of the suction cup 32 is distributed between the two hinge ears and is hinged to the hinge ears through the hinge shaft.

[0048] In order to facilitate the disassembly and installation of the adsorption mechanism 30, in some embodiments, the adsorption mechanism 30 is detachably fixed to the suspension platform 20. Thus, it is convenient to repair or replace the adsorption mechanism 30.

[0049] The specific structure of the detachable connection of the adsorption mechanism 30 is not limited. In some embodiments, the adsorption mechanism 30 includes a fixed base 33, and the fixed base 33 is fastened to the suspension platform 20. The telescopic driving member 31 is fastened and installed on the fixed base 33, thereby realizing the detachable connection with the suspension platform 20.

[0050] Multiple fixed bases 33 can be provided. For example, one fixed base 33 is provided at both ends of the telescopic driving member 31.

[0051] To guide the telescopic direction of the telescopic rod 311 and at the same time improve the strength in the radial direction. In some embodiments, the adsorption mechanism 30 includes a guide rod 34 and a guide sleeve 35. The guide sleeve 35 is fixed to the fixed seat 33. The guide rod 34 is inserted into the guide sleeve 35 and can slide along the axial direction of the guide sleeve 35. One end of the guide rod 34 is connected to the mounting seat 312. To improve the connection strength between the suction cup 32 and the suspension platform 20.

[0052] Please refer to Figure 2 and Figure 4 , and the specific structure of the lifting mechanism 40 is not limited. In some embodiments, the lifting mechanism 40 includes a lifting motor 41, a lifting rope 42, and a pulley 43. The lifting motor 41 and the pulley 43 are installed on the suspension platform 20. One end of the lifting rope 42 is fixed to the lifting motor 41. The lifting rope 42 passes through the pulley 43. One end of the lifting rope 42 passing through the pulley 43 can be connected to the wall-climbing robot 300. A hook can be provided at one end of the lifting rope 42 passing through the pulley 43 to facilitate the quick connection with the wall-climbing robot 300.

[0053] The lifting motor 41 can be a winch, and the lifting work is realized by driving the winding of the lifting rope 42 by the motor.

[0054] The pulley 43 is a fixed pulley 43, installed on the suspension platform 20. The lifting rope 42 passes through the pulley 43. One pulley 43 provides a force support point for the lifting rope 42.

[0055] To facilitate the installation and disassembly of the lifting mechanism 40, in some embodiments, the lifting mechanism 40 is detachably fixed to the suspension platform 20. Thus, it is convenient for maintenance and replacement. Specifically, both the lifting motor 41 and the pulley 43 are fixedly installed on the suspension platform 20 through fasteners.

[0056] In some embodiments, the suspension platform 20 includes a basket body 21 and a cross beam 22 located above the basket body 21. The basket body 21 is used to carry the operator. The cross beam 22 is located above the basket body 21 and is connected to the basket body 21.

[0057] A plurality of pulleys 43 are provided. One of the pulleys 43 is arranged on the cross beam 22 and is located in the middle of the basket body 21 in the length direction. In this way, when lifting the wall-climbing robot 300, the gravity support point of the wall-climbing robot 300 is in the middle of the basket body 21 in the length direction, so that the center of gravity will not undergo obvious displacement in the length direction of the basket body 21 before and after lifting.

[0058] In some embodiments, two pulleys 43 are provided on the cross beam 22. One of the pulleys 43 is arranged above the hoisting motor 41, and the hoisting motor 41 is arranged at one end of the hanging basket body 21 in the length direction. The other pulley 43 is located in the middle of the hanging basket body 21 in the length direction. The running route of the hoisting rope 42 is guided by the two pulleys 43, so that the hoisting rope 42 will not interfere with the operator's working area.

[0059] Further, in some embodiments, the cross beam 22 is distributed in the middle of the hanging basket body 21 in the width direction, so as to better stabilize the center of gravity.

[0060] In some embodiments, the suspension platform 20 includes a hanging basket body 21 and a roller assembly 23, and the roller assembly 23 is arranged at the bottom of the hanging basket body 21. This facilitates the movement of the hanging basket body 21. The roller assembly 23 can be a universal roller assembly 23.

[0061] The number of the adsorption mechanisms 30 is not limited. In some embodiments, four groups of adsorption mechanisms 30 are provided, and are symmetrically arranged in pairs on both sides of the suspension platform 20 in the length direction. It can be understood that each adsorption mechanism 30 has a telescopic driving member 31 and a suction cup 32, which improves safety and stability. And since each telescopic driving member 31 can adjust the extension amount according to the environment, it can thus adapt to a more complex wall surface 100.

[0062] Among them, the four groups of adsorption mechanisms 30 can be arranged on the hanging basket body 21. The hanging basket body 21 is of a cuboid structure, and the four groups of adsorption mechanisms 30 are arranged on the two end faces of the hanging basket body 21 in the length direction, and one adsorption mechanism 30 is arranged at the top and bottom of each end face.

[0063] In some embodiments, the lifting mechanism 10 includes a hoist, a mounting device 11 and a steel wire rope. The hoist is a power component and can be arranged in the suspension platform 20. The mounting device 11 is arranged in the suspension platform 20 and is used to automatically and quickly lock the safety steel wire rope when the steel wire rope suddenly breaks or the suspension platform 20 tilts to a certain angle, so as to ensure that the suspension platform 20 does not fall or continue to tilt.

[0064] It can be understood that the lifting platform further includes an electric control box 50, and the electric control box 50 is installed on the suspension platform 20. The electric control box 50 has a plurality of switching devices, and the plurality of switching devices are used to control the hoisting mechanism 40, the adsorption mechanism 30 and the lifting mechanism 10.

[0065] The above has described the embodiments of the present invention in detail with reference to the drawings, but the present invention is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present invention within the knowledge scope of those of ordinary skill in the art.
