[0002] The busbar is one of the basic components of the rigid contact net system, is used for clamping fixed contact line and bears transmission current, and the busbar elastically clamps the contact line through the own jaw and does not need to provide additional compensation tension to the contact line. The busbar is one of the important components of the rigid contact net construction when installing, and the quality of the busbar installation directly influences the flatness of the contact line.

[0003] At present, in the rigid contact net construction of urban rail transit, the busbar installation usually adopts two installation modes of ladder car and rail car. The length of the busbar is 12 meters, and generally needs 3 ladder cars to cooperate operation when installing by the ladder car mode, and the busbar is lifted to the installation position by manual. When manually constructing, the busbar is inevitably scratched or excessively bent, which may cause the damage of the busbar structure, and then influences the supporting capacity and causes the droop. Then a series of serious consequences are brought, including the contact line off the groove, the contact line arc, etc. The rail car installation is dangerous due to the limited metro line construction area, and the installation platform of the rail car busbar is large and heavy, which seriously influences the construction progress.

[0004] Therefore, the liftable busbar installation ladder car capable of automatically lifting the busbar is developed, and efforts are made to improve the problems of low flatness after the busbar installation and low construction efficiency in the busbar installation process caused by the manual climbing ladder car transporting the busbar.

Detailed Implementation

[0020] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0021] A liftable busbar installation ladder, such as Figures 1-5 As shown, the assembly includes a connecting shaft 1, track wheels 110, rotating rods 2, fixed rods 3, support rods 4, a standing platform 5, fixed handrails 10, a limiting frame 13, a limiting plate 14, an escalator 15, an adjustment assembly, and an extension assembly. The connecting shaft 1 has two sections, left and right. Track wheels 110 are rotatably connected to both the front and rear sides of the connecting shaft 1. Rotating rods 2 are rotatably connected to both the front and rear parts of the connecting shaft 1. Fixed rods 3 are rotatably connected between the rotating rods 2. Support rods 4 are connected between the upper sides of the rotating rods 2 connected to the same connecting shaft 1. A standing platform 5 is placed between the support rods 4. The standing platform 5 has a square slot to facilitate the construction personnel to go up and down. Four fixed handrails 10 are connected to the upper side of the standing platform 5. A limit frame 13 is connected to the lower middle part of the standing platform 5. The limit frame 13 is movably connected to the fixed rod 3. Limit plates 14 are rotatably connected to both the front and rear sides of the support rods 4. The limit plates 14 are slidably connected to the standing platform 5. The standing platform 5 is equipped with an adjustment component and an extension component. A ladder 15 is connected to the lower rear part of the standing platform 5.

[0022] like Figure 2 As shown, the adjustment assembly includes a junction box 6, a motor 7, a steel cable coil 8, and a control switch 9. The front of the support rod 4 is connected to the junction box 6. The upper middle part of the standing platform 5 is connected to the motor 7.
