Description

Technical Field

[0001] This utility model relates to the field of track duct installation technology, specifically to a lifting device for installing ducts above track areas. Background Technology

[0002] In rail transit depots, when air ducts need to be installed in operation and maintenance areas, the presence of numerous tracks on the ground makes installing air ducts above these tracks extremely difficult. Specifically, traditional installation machinery, such as large scissor lifts, struggles to access the track area, while rail-mounted boom lifts have limited load-bearing capacity, hindering large-scale air duct installation. Furthermore, conventional hoisting equipment requires alignment of the air ducts to be installed with existing ones before hoisting, but the ducts are fixed during transport and, upon arrival, their weight makes timely adjustment impossible, further complicating the alignment process. Therefore, a technical solution is urgently needed to address these issues. Utility Model Content

[0021] Example

[0022] like Figures 1 to 2 As shown, this utility model provides a lifting device for installing air ducts above a track area, including a lifting steel platform 1, a bidirectional moving device 2 for adjusting the horizontal position of the air duct is fixedly installed inside the lifting steel platform 1, a track wheel set 3 is fixedly installed at the bottom of the lifting steel platform 1, and a plurality of lifting rings 4 are fixedly connected to the top of the lifting steel platform 1, with an electric chain hoist connected to the top of the plurality of lifting rings 4.

[0023] As an advanced solution for a lifting device for installing air ducts above a track area, the bidirectional moving device 2 includes a first gearbox 6 and a second gearbox 7 fixedly installed on the inner wall of the lifting steel platform 1. Multiple conveying rollers 8 are rotatably connected inside the first gearbox 6, and multiple mounting rods 9 are rotatably connected inside the second gearbox 7. Multiple cams 10 are fixedly connected to the mounting rods 9. A first motor 11 for driving the first gearbox 6 and a second motor 12 for driving the second gearbox 7 are fixedly connected to the side wall of the lifting steel platform 1, respectively.

[0024] As an advanced solution for a lifting device for installing ducts above the track area, multiple mounting rods 9 are located below the conveyor roller 8, and when multiple cams 10 rotate to point upward, the horizontal height of the tip of the cam 10 exceeds the horizontal height of the conveyor roller 8.

[0025] As an advanced solution for a lifting device for installing air ducts above a track area, the track wheel set 3 includes a mounting strip 13 fixedly installed at the bottom of the lifting steel platform 1, with unidirectional track wheels 14 rotatably mounted on both sides of the mounting strip 13.

[0026] As an advanced solution for a lifting device for installing air ducts above the track area, multiple lifting rings 4 are fixed on the top two sides of the lifting steel platform 1, and the multiple lifting rings 4 are symmetrically distributed on the lifting steel platform 1.

[0027] As an advanced solution for lifting devices used to install ducts above track areas, multiple electric chain hoists are connected to the same control circuit system.

[0028] As a further explanation of this embodiment, the working process of this device in this embodiment is as follows: the track wheel set 3 of this device is placed on the track, and then the air duct is placed on the lifting steel platform 1. After the air duct is fixed, the device transports the air duct to the preset position along the track. Then, the bidirectional moving device 2 is activated to adjust the horizontal position of the air duct. Specifically, the first motor 11 drives the first gearbox 6 to drive multiple conveying rollers 8 to rotate, so as to drive the air duct placed on the transmission roller to move back and forth along the conveying direction of the conveying roller 8. At the same time, the second motor 12 drives the second gearbox 7 to drive multiple mounting rods 9 to rotate. The cams 10 fixedly installed on the mounting rods 9 rotate synchronously with the mounting rods 9. During the upward rotation of the multiple cams 10, the protruding part of the cam 10 supports the bottom of the air duct, so that the air duct moves back and forth along the rotation direction of the cam 10, thereby adjusting the position of the air duct on the lifting steel platform 1, so that the end of the air duct on this device is aligned with the end of the air duct that has already been installed. In this embodiment, the electric chain hoist needs to be installed on the floor slab in advance. The hoist hooks inside the electric chain hoist hook the lifting ring 4. Then, through the control circuit system, multiple electric chain hoists simultaneously lift the lifting steel platform 1, so that the lifting steel platform 1 rises in a horizontal state, which facilitates the batch splicing and installation of air ducts.
