Description

Technical Field

[0001] The present invention belongs to the technical field of equipment for the overhaul, maintenance and replacement operations of subway busbars, and particularly relates to a lifting operation device for installing busbars. Background Art

[0002] The environment in the subway tunnel is relatively complex, with a large amount of sewage components. When it directly drips or leaks onto the catenary equipment, it causes serious corrosion to the catenary equipment itself. In particular, the rigid overhead busbar has poor corrosion resistance and is easily corroded. In the rigid catenary suspension, the busbar span is large, the positioning clamp is prone to jamming, and due to factors such as the thermal expansion and contraction of the busbar itself, the misalignment between the clamp and the busbar, and the unclean surface, the busbar will be distorted and deformed. At the same time, an arcing phenomenon will also occur. The replacement of the busbar is basically carried out by manually lifting the busbar. Each busbar is more than ten meters long and weighs dozens of kilograms. Whether it is in the way of manpower + engineering vehicle or manpower + ladder truck, removing or installing the busbar is a very laborious and relatively risky operation. Therefore, improvements are proposed for the above problems. Summary of the Invention

[0026] Lifting operation device for busbar installation, such as Figures 1-2 As shown, it includes a working platform 2 installed on a flatbed truck 1. There are two groups of lifting devices 3 distributed along the length direction on the surface of the working platform 2, and a transverse movement mechanism 4 is installed at the upper end of the lifting device 3. The two groups of transverse movement mechanisms 4 are connected to the busbar 5 for temporary fixation, and the height and lateral position of the busbar 5 are adjusted to the installation position by the lifting device 3 and the transverse movement mechanism 4; in the above structure, by setting the lifting device 3 on the working platform 2 and the transverse movement mechanism 4 at the upper end of the lifting device 3, the mechanized lifting of the height and transverse movement position during the installation of the busbar 5 is realized. Just place the busbar on the transverse movement mechanism 3, through the combined operation of the linkage lifting and single-action fine adjustment of the lifting device 3, and in combination with the transverse movement mechanism 4 on the lifting device 3, the mechanized control of the lifting and transverse movement of the busbar 5 is realized, ensuring that the busbar 5 can be accurately adjusted, and solving the problems of high labor intensity and great potential safety hazards in the traditional lifting method of the busbar 5.

[0027] Such as Figure 3As shown in the figure, the specific structure of the lifting device 3 is as follows: The lifting device 3 includes a scissor lift platform 3-1. The base 3-2 at the lower end of the scissor lift platform 3-1 is fixed to the tabletop of the operation platform 2 by bolts, and the transverse movement mechanism 4 is installed on the top plate 3-3 at the upper end of the scissor lift platform 3-1. The scissor lift platform 3-1 is driven to lift by an electric cylinder 3-4. On both sides of the middle of the base 3-2, support locking columns 3-5 are fixed. A proximity switch for detecting the position of the top plate 3-3 is provided at the upper end of one of the support locking columns 3-5. Locking seats 3-7 for inserting and locking with the support locking columns 3-5 through locking pins 3-6 are fixed on both sides of the bottom surface of the top plate 3-3. And a warning light 3-8 controlled to turn on by the proximity switch trigger is provided on the bottom surface of the top plate 3-3. The lifting device 3 is mechanically locked by the support locking columns 3-5 and the locking pins 3-6. Before operation, the locking pin 3-6 is removed to release the lock. After the above locking pin 3-6 is removed, the proximity switch is triggered to turn on the warning light 3-8 to start working. After the lifting device 3 is reset, the mechanical lock is carried out with the locking pin 3-6 to trigger the proximity switch to turn off the warning light 3-8 to stop working, realizing the mechanical locking and alarm functions of the lifting device 3, ensuring the driving safety and operation safety of the vehicle. Specifically, the distance between the two groups of the lifting devices 3 is determined according to the length of the busbar 5. Among them, when the lifting devices 3 of each group are lifted simultaneously, it is used to adjust the overall height of the busbar 5, and when the lifting device 3 is lifted alone, it is used for fine adjustment of the height of the corresponding end of the busbar 5.

When the limiting seat 4-7 is rotated until the positioning rod 4-9 is adapted to the positioning groove 4-10, the limiting of the busbar 5 installed in the limiting seat 4-7 is realized, ensuring the safety of the busbar 5 during the lifting and lateral movement processes.

On both sides of the upper end surface of the support seat 4-1, L-shaped side plates are fixed facing each other, and the lead screw 4-2 and the guide shafts 4-3 on both sides thereof are both located between the two L-shaped side plates. Both ends of the lead screw 4-2 are rotatably installed on the L-shaped side plates on the same side, and one end of the lead screw 4-2 extends out of the L-shaped side plate on the same side and is fixedly connected to the handwheel 4-6. Both ends of the guide shaft 4-3 are connected to the corresponding L-shaped side plates; specifically, the rubber buffer pad 4-11 is in the shape of a right trapezoid with an inclined surface facing away from the L-shaped side plate on the same side.
