[0002] A plane is suspended by four points using steel wire ropes, which can drive the plane up and down. The height adjustment through longitudinal lifting can ensure that the flat plate remains level. However, due to the ductility of the steel wire ropes during operation, the plane may tilt.

[0003] For example, a Chinese patent (application number: 202021273822.4) discloses a four-point leveling structure for a precision equipment work surface, which specifically relates to the field of mechanical processing, including a workbench, a base, and an adjustment support screw. The top surface of the base is fixedly connected with a scissor-type buffer structure and a measuring plate connecting block. The inner side of the scissor-type buffer structure is movably connected to the outer side of the adjustment support screw. The top surface of the measuring plate connecting block is fixedly installed with a measuring plate, and a control adjustment structure is fixedly installed on one side of the base. The outer side of the top of the adjustment support screw is fixedly connected with a marking component. However, this structure cannot be applied to hoisting equipment, so it is necessary to develop a device that can perform leveling operations on the plane during hoisting operations.

[0006] As a further improvement of the above technical solution:

[0007] The positioning part comprises two hinged seats which are symmetrically distributed with the center line of the plate as the axis. A cantilever connected to the fixed end of the leveling rope is arranged on the hinged seat, and a force sensor is arranged at the connection between the cantilever and the hinged seat.

[0008] The adjustment part comprises two guide wheels which are symmetrically distributed with the center line of the flat plate as an axis, and a fine adjustment module connected with the movable end of the leveling rope is arranged between the two guide wheels.

[0019] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0020] like Figure 1-3 As shown, the plane four-point leveling device of this embodiment includes a plane mechanism 1 and a leveling mechanism 2. The plane mechanism 1 includes a plate 3. A pulley 4 and a measuring module 5 are provided on the upper part of the plate 3. The measuring module 5 adopts a longitudinal and transverse level. The leveling mechanism 2 includes a lifting module located above the plate 3. The lifting module includes a positioning part 6, a lifting power part 7 and an adjusting part 8 which are sequentially installed along the length direction of the plate 3. A leveling rope 9 connected to the positioning part 6 and the adjusting part 8 respectively is wound on the lifting power part 7. The leveling rope 9 is made of steel cable. The leveling rope 9 is adjusted by the adjusting part 8 to level the end of the plate 3. Then, the measuring module 5 is used to observe whether the plate 3 remains horizontal. The leveling rope 9 can be used to level the plate 3 once, and then the adjusting part 8 can be used to adjust the plate 3 for a second time to avoid the deflection of the plate 3 due to the ductility of the steel wire rope.

[0021] The positioning portion 6 includes two articulated seats 10 which are symmetrically distributed with the center line of the flat plate 3 as the axis. A cantilever 11 connected to the fixed end of the leveling rope 9 is provided on the articulated seat 10. A force sensor 12 is provided at the connection between the cantilever 11 and the articulated seat 10. The force sensor 12 can monitor the tension applied to the cantilever 11. When the tension applied to the two force sensors 12 is the same, it indicates that the ends of the two articulated seats 10 remain flush.

[0022] The adjustment part 8 includes two guide wheels 13 which are symmetrically distributed with the center line of the plate 3 as the axis. The guide wheels 13 are also equipped with force sensors 12. The values ​​of the four force sensors 12 can be combined with the data of the longitudinal and transverse level to determine whether the plate 3 is in a horizontal state. A fine-tuning module connected to the movable end of the leveling rope 9 is provided between the two guide wheels 13.

[0023] The fine-tuning module includes a positioning plate 14, and positioning sleeves 15 are provided on both sides of the positioning plate 14. An adjusting sleeve 16 for connecting the movable end of the leveling rope 9 is threaded in the positioning sleeve 15. The movable end of the leveling rope 9 can be fine-tuned by the adjusting sleeve 16, thereby ensuring that the plate 3 is in a horizontal state.

[0024] The lifting power unit 7 includes a winding roller 17 , one end of which is connected to a power source, and one end of a leveling rope 9 is connected to the winding roller 17 , and the height of the flat plate 3 can be adjusted by rotating the winding roller 17 .

[0025] There are four leveling ropes 9 , two of which are located between the positioning portion 6 and the winding roller 17 , and the other two are located between the adjusting portion 8 and the winding roller 17 .

[0026] There are four pulleys 4 , which are respectively located at four corners of the plate 3 .

[0027] Working principle: First, four leveling ropes 9 are used to connect the plane mechanism 1 and the leveling mechanism 2. One end of two leveling ropes 9 is connected to two hinge seats 10 respectively, and the other end is wound on the winding roller 17. After one end of the other two leveling ropes 9 is wound on two guide wheels 13, the movable end is connected to the adjustment sleeve 16, and the other end is placed on the winding roller 17. The lifting and lowering operation of the flat plate 3 and the preliminary leveling operation can be completed through the winding roller 17. Under the action of gravity, the leveling ropes 9 have the ductility of the material. The flat plate 3 will be tilted due to the rolling characteristics of the articulated seat 10 and the pulley 4, and the positioning part 6 will maintain self-balance under the action of gravity. At this time, the length of the two leveling ropes 9 in the adjusting part 8 can be tightened or loosened by adjusting the sleeve 16. During the adjustment process, it is determined whether the flat plate 3 is in a horizontal state by observing the value of the measuring module 5. It is also possible to determine whether the flat plate 3 is in a horizontal state by the value of the force sensor 12 installed at the connection between the cantilever 11 and the articulated seat 10 and the guide wheel 13.
