[0038] Multiple first support arms 2 are retractably provided on the base 1. The multiple first support arms 2 are located on both sides of the base 1 and are symmetrically arranged. In this embodiment, four first support arms 2 are provided and are symmetrically arranged on both sides of the base 1. Specifically, multiple hydraulic rods 11 are provided on the base 1. The multiple hydraulic rods 11 are used to drive the multiple first support arms 2 to extend and retract, so as to realize the automatic extension and retraction of the first support arms 2.

[0039] As attached Figure 3 As shown, each first support arm 2 is provided with a lower claw 3; the lower claw 3 is provided with a bending part 13 and a limiting plate 12, wherein the bending part 13 is integrally formed on the upper end of the lower claw 3, and the limiting plate 12 is connected and fixed to the lower end of the lower claw 3.

[0040] The work platform 4 is provided with multiple retractable second support arms 5, which are located on both sides of the work platform 4 and are symmetrically arranged. In this embodiment, there are four second support arms 5, which are symmetrically arranged on both sides of the work platform 4.

[0041] As attached Figure 4 As shown, each second support arm 5 is provided with an upper claw 6, wherein a limit plate 12 is provided at the bottom of the upper claw 6, and a fixing pin 14 is also provided on the upper claw 6, the fixing pin 14 vertically penetrating the upper claw 6.

[0042] As attached Figure 5 As shown, the first support arm 2 and the second support arm 5 are offset. When the scissor lift 8 is folded, the lower claw 3 on the first support arm 2 and the upper claw 6 on the second support arm 5 are on the same horizontal plane.

[0043] As attached Figure 1-2 As shown, a rotating seat 7 is rotatably mounted on the top surface of the work platform 4, and a lifting assembly is mounted on the rotating seat 7. The lifting assembly is used to lift materials from the ground onto the work platform 4.

[0044] Specifically, the lifting assembly includes a support column 16, a first lifting boom 19, a second lifting boom 21, an adjusting arm 23, and a lifting wire rope 24. The support column 16 is fixedly connected to a rotating base, and a mounting platform 17 is fixedly installed on the support column 16. A second drive device 18 is installed on the mounting platform 17. In this embodiment, the second drive device 18 is a winch. The first lifting boom 19 is fixedly installed at the top of the support column 16, and a first pulley 20 is rotatably installed at the end of the first lifting boom 19. The second lifting boom 21 is hinged to the first lifting boom 19 away from the first pulley 20. The second lifting arm 21 has a second pulley 22 rotatably mounted at the end away from the first lifting arm 19; the lower end of the adjusting arm 23 is hinged to the support column 16, and the upper end of the adjusting arm 23 is connected and fixed to the second lifting arm 21 to form a support for the second lifting arm 21; one end of the lifting wire rope 24 is wound on the second drive device 18 and driven by the second drive device 18; the other end of the lifting wire rope 24 passes through the first pulley 20 and the second pulley 22 in sequence and extends downward; the lifting wire rope 24 is used to lift materials.

[0045] During operation, the second drive device 18 first drives the lifting wire rope 24 to extend. The lifting wire rope 24 passes through the first pulley 20 and the second pulley 22 and cooperates with the first pulley 20 and the second pulley 22. After the extension end of the lifting wire rope 24 reaches the ground, the ground staff fixes the material to the extension end of the lifting wire rope 24. Then the second drive device 18 drives the lifting wire rope 24 to retract. When the extension end of the lifting wire rope reaches the working platform 4, the staff moves the material onto the working platform 4.

[0046] Because the rotating seat 7 is rotatably mounted on the working platform 4, the entire lifting assembly can be operated 360 degrees.

[0047] In a preferred embodiment, an adjusting plate 25 is fixedly installed on the second lifting boom 21. The adjusting plate 25 has multiple adjusting holes 26. The upper end of the adjusting arm 23 cooperates with the adjusting holes 26 on the adjusting plate 25. By changing different adjusting holes 26, the extension length of the second lifting boom 21 can be adjusted, thereby realizing the lifting of materials at different distances.

[0048] Folding plates 15 are provided at both ends of the work platform 4. The folding plates 15 are hinged to the work platform 4. In this embodiment, the folding plates 15 are hinged to the work platform 4. The folding plates 15 are perpendicular to the second support arm 5. When the folding plates 15 are unfolded, they overlap the second support arm 5. By hinged to the folding plates 15 on the work platform 4, the area of ​​the work platform 4 can be increased when unfolded. This not only allows more installers to be accommodated, but also ensures the safety of the workers.

[0049] The base 1 has multiple casters 27 at its bottom to facilitate movement.

[0050] As attached Figure 6 As shown, this application provides an application example of an automatic lifting platform for installing a scissor lift elevator steel structure, which is used in a steel structure shaft composed of multiple columns 29 and beams 28.

[0051] Specifically, the base 1 is connected to the crossbeam 28 via the lower claws 3 on the first support arms 2 on both sides. The limiting plate 12 on the lower claw 3 abuts against the bottom of the crossbeam 28 to prevent the base 1 from tipping over. The bent part 13 on the lower claw 3 is tightly fastened to the side of the crossbeam 28 to prevent the lower claw 3 from slipping off the crossbeam 28, thereby effectively ensuring the stability of the base 1.

[0052] The work platform 4 is connected to the upper crossbeam 28 via the upper claws 6 on the second support arms 5 on both sides. The limiting plate 12 of the upper claw 6 abuts against the bottom of the upper crossbeam 28 to prevent the work platform 4 from tipping over. The upper claw 6 is locked to the upper crossbeam 28 by the fixing pin 14, thereby improving the stability of the work platform 4.

[0053] The work platform 4 is lifted by a scissor lift 8 between the base 1 and the work platform 4, and the first drive device 10 is configured to cooperate with the scissor lift 8 to realize the automatic lifting of the work platform 4. When the scissor lift 8 is folded, the lower claw 3 on the first support arm 2 and the upper claw 6 on the second support arm 5 are on the same horizontal plane, so as to avoid the problem that the gap between the upper and lower crossbeams 28 is too large and cannot be climbed, while saving more placement space.

[0054] The automatic lifting platform of this utility model has an assembly structure that can be disassembled into several parts for easy transportation and to save space. At the same time, the assembly structure can be reused.

[0055] The working process of this utility model is as follows:

[0056] After the bottommost column 29 and crossbeam 28 are installed, the entire retracted automatic lifting platform is pushed into the shaft. The first support arm 2 on the base 1 is automatically extended via the hydraulic rod 11, fixing the lower chuck 3 to the bottommost crossbeam 28, thus completing the installation of the base 1. The work platform 4 is then lifted to the second-layer crossbeam 28 using the first drive device 10, telescopic rod 9, and scissor lift 8. The second support arm 5 is manually extended, and the upper chuck 6 is fixed to the crossbeam 28 of that layer. The required materials for the second layer are then hoisted onto the work platform 4 using the lifting assembly. At this point, the second-layer columns 29, crossbeam 28, and their smaller components can be installed on the work platform 4. After the second layer is completed, the materials are then... The hydraulic rod 11 retracts the first support arm 2 on the base 1, and through the cooperation of the first drive device 10, the telescopic rod 9 and the scissor lift 8, the base 1 is retracted to the second-level crossbeam 28. The first support arm 2 extends and the lower pawl 3 is fixed to the second-level crossbeam 28. Through the cooperation of the first drive device 10, the telescopic rod 9 and the scissor lift 8, the work platform 4 is raised to the third-level crossbeam 28. The second support arm 5 extends and the upper pawl 6 is fixed to the third-level crossbeam 28. The fixing pin 14 is inserted to complete the installation of the work platform 4. The above actions are repeated until the installation is finally completed. When it is necessary to withdraw after the operation is completed, the opposite action of climbing is performed to withdraw.

[0057] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model; all technical solutions formed by equivalent transformation or equivalent substitution fall within the scope of protection of this utility model.
