The hydraulic slewing bearing can drive the lifting platform to rotate relative to the frame 14 to meet the use requirements of the construction equipment.

[0036] refer to Figure 2 and Figure 3 As shown, the support base 2 is frame-shaped, and the support base 2 is provided with four first vertical beams 2-2. The first vertical beams 2-2 are hollowly arranged, and the four first vertical beams 2-2 are located at the four corners of the frame-shaped support base 2. Along the width direction of the support base 2, a first cross beam 2-1 and a second cross beam 2-5 are connected between two adjacent first vertical beams 2-2. The height of the second cross beam 2-5 is greater than the height of the first cross beam 2-1, and the second cross beam 2-5 is located below the first cross beam 2-1; along the length direction of the support base 2, a third cross beam 2-4 and a fourth cross beam 2-6 are connected between two adjacent first vertical beams 2-2.

The Y-axis support beam 7-1 supports the bottom plate, and the bottom plate supports the X-axis support beam 5-1. A Y-axis linear drive component is arranged between the Y-axis support beam 7-1 and the bottom plate. The Y-axis linear drive component is a Y-axis drive cylinder 23, and the Y-axis linear drive component is connected to the control component.

[0038] The length of the Y-direction support beam 7-1 is less than the length of the fourth cross beam 2-6, and the adjacent two Y-direction support beams 7-1 are arranged at a distance, and the ends of the multiple Y-direction support beams 7-1 are provided with a fifth cross beam 7-2, and the fifth cross beam 7-2 is connected to the Y-direction support beams 7-1; refer to Figure 5 and Figure 6As shown, the support frame 4 includes multiple second vertical beams 4-1, the positions of the second vertical beams 4-1 correspond one to one with the positions of the first vertical beams 2-2, the second vertical beams 4-1 are inserted into the hollow of the first vertical beams 2-2, and a lifting component is arranged between the second vertical beams 4-1 and the first vertical beams 2-2, the lifting component 3 is specifically a lifting cylinder 25, the fixed end of the lifting cylinder 25 is fixed to the outer side of the first vertical beam 2-2, and the telescopic end of the lifting cylinder 25 is fixed to the second vertical beam 4-1.

The sixth beam 4-2 is arranged along the length direction of the support frame 4, and the sixth beam 4-2 on both sides supports multiple seventh beams 4-3. The width of the sixth beams 4-2 on both sides, that is, the support frame 4 is smaller than the width of the track air duct, and the lower protruding side of the track top air duct is placed on one side of the support frame 4 in the width direction, so as to avoid interference between the lower protruding side of the track top air duct and the support frame 4.

[0040] In this embodiment, the lifting platform includes an upper platform 8 and a lower platform 6. A scissor-type lifting component 1 is arranged between the upper platform 8 and the lower platform 6. The scissor-type lifting component 1 is an existing scissor-type lifting mechanism.

In this way, when the scissor lift 1 is retracted, the limit rod 28 is rotated relative to the scissor lift and pushed toward the center position of the construction equipment so that the bent end 28-2 of the limit rod is located on the lower side of the lower platform 6 to lock the scissor lift 1.

[0042] It is easy to understand that the length of the lower platform 6 is longer than that of the upper platform 8. A control box 9 is set at the lower platform 6. Taking into account the need for workers to stand on the upper platform 8, guardrails are set on the sides of the upper platform 8 to ensure work safety. A telescopic ladder is set on one side of the upper platform 8 or the control box 9. The telescopic ladder is an existing structure. After the telescopic ladder is extended, it is convenient for workers to go up to the upper platform 8.

[0043] Taking into account that the construction environment is uneven and the mass of the rail top air duct is heavy, in order to ensure stable construction, a plurality of telescopic legs 10 are arranged at the lower platform 6, specifically, four telescopic legs 10 are arranged, and the four telescopic legs 10 are placed under the four corners of the upper platform 8.

[0046] The construction equipment provided in this embodiment has a traveling mechanism connected to a frame 14 to drive the frame 14 to move on site, and the frame 14 supports the lifting platform. After the prefabricated parts of the rail-top air duct are placed on the support frame 4, the lifting platform can drive the prefabricated parts to lift. After lifting to a set height, the prefabricated parts are driven by the lifting assembly 3, the X-axis moving assembly 5 and the Y-axis moving assembly 7 to achieve multi-directional movement, so that the reserved steel bars of the rail-top air duct are aligned with the installation holes on the top of the tunnel.
