The implementations described in the following exemplary examples do not represent all implementations consistent with the utility model. Rather, they are merely examples of apparatus consistent with aspects of the utility model as detailed in the accompanying claims.
As shown in fig. 1, 2 and 3, the present embodiment provides a telescopic structure applied to a rotating cantilever device of a mobile catenary, the rotating cantilever device in the present embodiment is rotatably mounted on a stand column 14, and the telescopic structure 2 is mounted at a free end of the rotating cantilever device 1; also comprises a carrier rope 3 and/or a contact line 4;
the carrier rope 3 and/or the contact line 4 are/is fixed on the telescopic structure 2, and the carrier rope 3 and/or the contact line 4 are/is used for driving the rotating wrist device 1 to switch between a working position and a non-working position;
when the carrier rope 3 and/or the contact line 4 move towards the side of the railway, the carrier rope 3 and/or the contact line 4 can pull the telescopic structure 2 to stretch in the length direction of the rotating wrist device 1.
As a preferred embodiment, the free end of the swivel arm device in this embodiment is provided with a mounting plate 5, and the telescopic structure 2 comprises at least a support 6, a slide rod 7 and a telescopic member 8;
one end of the sliding rod 7 is fixed on the mounting plate 5, and the other end of the sliding rod 7 is slidably arranged on the supporting piece 6 in a penetrating manner; one end of the telescopic component 8 is connected with the mounting plate 5, and the other end of the telescopic component 8 is connected with the supporting piece 6; the support 6 is pulled to drive the telescopic part 8 to extend in the process of rotating the rotating wrist device to the side of the railway. The other end of the slide rod 7 is provided with an anti-slip joint 9. The anti-slip joint 9 is provided mainly to prevent the support 6 from coming off the slide rod 7. The number of the sliding rods 7 is at least two.
As a preferred embodiment, the telescopic member 8 in this embodiment includes at least a sliding shaft 10 and a spring 11, one end of the sliding shaft 10 is fixed on the supporting member 6, and the other end of the sliding shaft 10 is penetrating through the mounting plate 5; it is necessary here that the other end of the sliding shaft 10 is slidably mounted on the mounting plate. The spring 11 is sleeved on the sliding shaft 10, one end of the spring 11 is fixed on the mounting plate 5, and the other end of the spring 11 is fixed on the supporting piece 6.
As shown in fig. 2, when the rotating wrist device rotates towards the side of the railway, the rotating wrist device swings towards the side of the railway gradually, the pulled direction of the carrier rope and the contact line gradually approaches to the length extending direction of the rotating wrist device, at this time, the carrier rope and/or the contact line pulls the telescopic structure to extend in the length direction of the rotating wrist device, and the spring can be stretched; by using the telescopic structure, the carrier ropes and the contact wires fixed on the telescopic structures can be further pulled forward to form certain stroke compensation.
When the swivel arm device swings over the railway as shown in fig. 1, the direction in which the carrier cable and the contact line are pulled when the swivel arm device is positioned at the square of the railway is substantially perpendicular to the longitudinal direction of the swivel arm device in terms of space. In this case, since the tensile force in the length direction of the spring is gradually reduced, the spring is gradually retracted.
On the other hand, the present embodiment further includes a carrier cable clamping seat 12 and/or a contact line clamping seat 13, where the carrier cable clamping seat 12 is disposed at the upper end of the support member 6, and the contact line clamping seat 13 is disposed at the lower end of the support member 6.

as shown in fig. 1, the swivel arm assembly is in the working position and the freight train is driven into or out of the freight loading and unloading yard, at which time the pantograph of the freight train is lifted up to take electricity from the contact line 4.
When the loading and unloading operation is required for the freight train, the rotating cantilever device is required to swing to the side of the railway (the power device is not shown in the drawing in the embodiment), at this time, the carrier rope 3 and/or the contact line 4 are pulled by the power device to move, and the power cantilever is driven to rotate together in the moving process of the carrier rope 3 and/or the contact line 4. By utilizing the telescopic structure 2 provided by the embodiment, when the rotating wrist arm device 1 rotates to the side of the railway, certain stroke compensation is formed by utilizing the telescopic structure 2, so that the carrier rope 3 and the contact line 4 can be further stretched and moved, the carrier rope 3 and the contact line 4 can be effectively tensioned, the rotating wrist arm device can be driven to further move to the side of the railway, the space above the railway can be effectively reserved, the loading and unloading operation of a freight train is facilitated, and the safety of the loading and unloading operation of the freight train by adopting hoisting equipment is ensured.
When the cargo loading and unloading is completed, the carrier rope 3 and the contact line 4 rotate from the non-working position (the side of the railway) to the working position (the upper side of the railway) again.
It should be noted that, the dragging of the carrier cable and the contact line can be realized by adopting a power device, such as a dragging motor and a balance weight, wherein one ends of the carrier cable and the contact line are directly or indirectly arranged on the dragging motor, and the balance weight is arranged at the other ends of the carrier cable and the contact line; when the dragging motor rotates forwards, the weight at the other end is driven to rise by the carrier rope and the contact line, so that the rotating cantilever device can swing from the upper part of the railway to the side of the railway; when the dragging motor reverses and drives the weight at the other end to descend through the carrier rope and the contact line, the swinging of the rotating cantilever device from the side edge of the railway to the upper side of the railway can be realized. This is just one example, but not limited to this example.
While embodiments of the present utility model have been shown and described above, it will be understood that the above embodiments are illustrative and not to be construed as limiting the utility model, and that variations, modifications, alternatives and variations may be made to the above embodiments by one of ordinary skill in the art within the scope of the utility model.
