[0038] Specifically, the hoisting mechanism comprises a positioning mechanism 5 arranged above the lifting ring 4, and the positioning mechanism 5 comprises a fixed plate 51 fixedly connected to the bottom of the two groups of mounting beams 11.

The fixed plate 51 is provided with a through hole 56, and the traction rope 37 is arranged at the position of the through hole 56.

[0039] Finally, the two groups of scissor assemblies 6 are arranged between the lifting ring 4 and the positioning mechanism 5 to ensure the stable movement of the lifting ring 4. The scissor assembly 6 comprises two groups of second sliding rails 61 which are fixedly connected to the bottom of the fixed plate 51 and the top of the lifting ring 4 respectively. Two groups of second sliding blocks 62 are slidingly connected to the second sliding rails 61. The scissor assembly 6 further comprises a plurality of scissor plates 63 which are arranged in a cross shape and rotatably connected at both ends of adjacent two groups of scissor plates 63.

The scissor assembly 6 further comprises two groups of fixed blocks 64 which are fixedly connected to the bottom of the fixed plate 51 and the top of the lifting ring 4 respectively.

Through the arrangement of the two groups of scissor assemblies 6, the stability of the lifting ring 4 during the up and down movement is ensured.

[0040] In this embodiment, the mounting frame 1 of the lifting mechanism is assembled by bolt connection. When the lifting mechanism needs to be used, the workers can conveniently transport each component to the work site, and then assemble the two groups of mounting beams 11, the first connecting column 12, the second connecting column 13 and the third connecting column 14 by bolts, and at the same time, an inclined support is arranged between the second connecting column 13 and the third connecting column 14 to increase the structural strength. After the assembly of the mounting frame 1 is completed, the components such as the driving mechanism 2, the traction assembly 3, the lifting ring 4, the positioning mechanism 5 and the scissor assembly 6 are installed according to the corresponding connection relationship, so that the lifting mechanism has working conditions.

[0041] When it is necessary to move the lifting mechanism to the profile lifting position, the first servo motor 24 in the driving mechanism 2 is started. After the first servo motor 24 is started, the output end drives the gear 25 to rotate. Since the gear 25 is engaged with the rack 26 mounted on the top of the cross beam 21, and the position of the rack 26 is fixed, the gear 25 will move along the length direction of the rack 26 during rotation. At the same time, the top of the two groups of cross beams 21 is provided with the first sliding rail 22, and the first sliding block 23 slidingly connected to the first sliding rail 22 is fixedly connected to the bottom of the two groups of mounting beams 11. During the movement of the mounting frame 1 driven by the gear 25, the first sliding rail 22 and the first sliding block 23 play a limiting role to ensure the stable movement of the mounting frame 1, and finally the lifting mechanism is moved to the appropriate position above the profile.

[0042] After the profile to be hoisted is connected with the lifting rings 4, the second servo motor 32 in the traction assembly 3 is started. After the second servo motor 32 is started, the output end thereof drives the winding disc 33 to rotate. The winding disc 33 is wound with two groups of traction ropes 37, one group of traction ropes 37 is connected with the lifting rings 4 in sequence through the first pulley 34, the second pulley 35 and the third pulley 36, and the other group of traction ropes 37 is connected with the lifting rings 4 in sequence through the second pulley 35 and the third pulley 36.

[0043] When the winding disc 33 rotates forward, the traction ropes 37 are wound on the winding disc 33, thereby driving the two groups of lifting rings 4 to move upward and lift the profile. During the upward movement of the lifting rings 4, the scissor assembly 6 plays a role to ensure the stable movement of the lifting rings 4. Specifically, the second sliding block 62 on the second sliding rail 61 slides on the second sliding rail 61 along with the movement of the lifting rings 4, and the plurality of groups of scissor plates 63 which are arranged in cross and rotationally connected at both ends are correspondingly expanded or contracted, and the connecting plates 65 rotationally connected at the side of the fixed blocks 64 also cooperate with the movement of the scissor plates 63, so that the lifting rings 4 remain stable during the upward and downward movement.

[0044] When the lifting rings 4 move to the highest point, the positioning mechanism 5 starts to play a role. The protrusions 54 on the moving blocks 55 installed at the top of the lifting rings 4 are inserted into the grooves 53 of the fixed cylinders 52, and the bottom of the fixed cylinders 52 is in contact with the moving blocks 55, so that the stability between the fixed plates 51 and the lifting rings 4 is ensured. At this time, the installation frame 1 is moved through the driving mechanism 2, which can effectively prevent the profile from shaking and ensure the safety and stability of the hoisting process.

[0045] When the hoisting mechanism moves to the placement position of the profile, the second servo motor 32 is started to rotate reversely. When the winding disc 33 reversely rotates, the traction ropes 37 are loosened from the winding disc 33, and the two groups of lifting rings 4 move downward under the action of gravity and place the profile. Similarly, during the downward movement of the lifting rings 4, the scissor assembly 6 ensures the stable descent of the lifting rings 4 until the profile is safely placed at the designated position. After the hoisting work is completed, the staff can disassemble the bolts between the parts of the hoisting mechanism, disassemble the installation frame 1 and other parts, and conveniently carry and transport, so as to be used in other work sites next time.

[0046] The above specific embodiments are only optional embodiments of the present application, and based on the technical scheme of the present application and the related inspiration of the above embodiments, the person skilled in the art can make various alternative improvements and combinations on the above specific embodiments.
