As shown in fig. 1, the embodiment provides a moving mechanism for moving a catenary, which includes a cantilever structure 1 and a sliding mechanism 2, and further includes a catenary cable 3 and/or a contact line 4; the traditional method is that a carrier cable 3 and a contact wire 4 are fixed on a rotating cantilever, the carrier cable 3 and/or the contact wire 4 are not fixed on a cantilever structure 1, and the carrier cable 3 and/or the contact wire 4 move relative to the cantilever structure 1 through a sliding mechanism 2; the wrist-arm structure 1 in this embodiment may be provided at the upright 5.
Wherein fig. 1 is a schematic view of the sliding of the messenger 3; fig. 2 is a schematic view of the sliding of the contact line 4; fig. 3 is a schematic view of the messenger wire 3 and contact wire 4 sliding.
In the present embodiment, the sliding mechanism 2 is configured to adopt any one of the following:
as shown in fig. 4, the first: the cantilever structure 1 is provided with a chute 6, the carrier cable 3 is arranged on a clamping mechanism 7, and the clamping mechanism 7 can slide in the chute 6; in this embodiment, the clamping mechanism 7 clamps the carrier cable 3, and drives the clamping mechanism to move in the chute 6 under the condition that the carrier cable 3 is dragged.
As shown in fig. 5, the present embodiment further includes a stopper 8, and when the stopper holding device moves on the slideway and contacts the stopper 8, the wrist-arm structure 1 can be driven to further rotate.
As shown in fig. 6, in addition to fig. 5, a force transmission mechanism is provided, and in this embodiment, an elastic force transmission member 9, preferably a spring, is used. The force transmission mechanism is used for indirectly or directly acting the pushing force or the pulling force formed in the moving process of the carrier cable 3 on the cantilever structure 1 so as to push or pull the cantilever structure 1 to rotate. In a preferred embodiment, as shown in fig. 6, the carrier cable is moved to the right to pull the gripping mechanism to move to the right, the elastic force-transmitting member is stretched, and the elastic force-transmitting member pulls the stopper to rotate the cantilever structure.
As a preferred embodiment, as shown in fig. 7, the arrangement of the sliding mechanism 2 can be realized by the way that the sliding rod 10 is matched with the sliding ring 11, so that the sliding mechanism 2 can move relative to the cantilever structure 1;
in the embodiment, the slip ring 11 is arranged on the cantilever structure 1, the slide rod 10 or the sliding part is arranged in a sliding manner with the slip ring 11, the catenary 3 is clamped on the slide rod 10 through the clamping mechanism 7, the arrangement structure of the contact wire 4 is similar, when the catenary 3 moves, the slide rod 10 is pulled to move in the slip ring 11, and the situation that the catenary 3 can move relative to the cantilever structure 1 by using the sliding mechanism 2 is realized.
As shown in fig. 8, the messenger wire 3 and the contact wire 4 can be moved by a rotation device 13, and the rotation device 13 is provided with a rotation support shaft 14, that is, the sliding structure is directly arranged on the cantilever structure 1, or indirectly arranged on the cantilever structure 1, and only the messenger wire 3 can be moved, or both the messenger wire 3 and the contact wire 4 can be moved, as shown in fig. 9.
The force transmission mechanism is used for indirectly or directly acting the thrust or the tension formed in the moving process of the carrier cable 3 and/or the contact line 4 or the sliding mechanism 2 on the cantilever structure 1 so as to push or pull the cantilever structure 1 to rotate; or the cantilever structure 1 rotates, and thrust or tension is formed by the force transmission mechanism and directly or indirectly acts on the sliding mechanism 2, so that the catenary cable 3 and/or the contact line 4 are driven to move.
The force transmission mechanism adopts an elastic force transmission piece 9, the elastic force transmission piece 9 is arranged outside the sliding mechanism 2, and the sliding mechanism 2 is pushed or pulled to move from the outside; or the elastic force transmission piece 9 is arranged inside the sliding mechanism 2 and pushes or pulls the sliding mechanism 2 to move from the inside; either inside or outside the sleeve 16 of said elastic force-transmitting member 9, pushing or pulling the sleeve 16 to move.
As shown in fig. 10, the elastic force transmission member 9 is disposed on the left side of the sliding ring 11, and the clamping mechanism 7 is disposed on the sliding rod 10, where the clamping mechanism 7 may be disposed directly on the sliding rod 10, or may be disposed on the sliding rod 10 through a connecting member, which may be integrally formed with the sliding rod 10, or may be fixedly connected thereto. When the carrier cable 3 moves rightwards, the elastic force transmission piece 9 is compressed to form thrust to push the cantilever structure 1 to rotate. When the elastic force transfer member 9 is arranged on the right side, assuming that the catenary 3 moves to the right, the tension formed by the elastic force transfer member 9 pulls the wrist-arm structure 1 to rotate.
Fig. 11 is a schematic structural view showing that the elastic force-transmitting member 9 is arranged on the right side of the slip ring 11.
As shown in fig. 12, the sliding mechanism 2 can also adopt another moving mechanism, and this embodiment directly or indirectly arranges the sleeve 16 on the wrist-arm structure 1, including only the pushing member 15, as shown in fig. 11. The wrist arm is rotated by the pushing member 15.
As shown in fig. 13, the resilient force-transmitting member 9 is provided directly on the messenger wire 3. One end of the elastic force-transmitting member 9 is arranged on the carrier cable 3 and the other end acts directly or indirectly on the sleeve 16 to push or pull the sleeve 16 and thus the cantilever structure 1.
As shown in fig. 14, in the case that the pushing member 15 and the elastic force-transmitting member 9 are provided, the pushing member 15 is moved by the compression of the right movement of the catenary 3, the elastic force-transmitting member 9 is compressed, and the pushing force formed by the elastic force-transmitting member 9 acts on the sleeve member 16, so as to push the rotation of the cantilever structure 1.
Of course the sleeve 16 can be arranged directly or indirectly on the wrist-arm structure 1, fig. 15 shows a sleeve 16 arranged on the rotation support shaft 14 of the rotating means 13 through an intermediate piece 17, the intermediate piece 17 comprising a cross bar 18 and a holder 19;
in addition, supplementary explanation is needed, the catenary 3 can be directly arranged in the external member 16 in a penetrating way, of course, the catenary 3 can be broken, one moving member 12 is arranged in the external member 16 in a penetrating way, and two ends of the moving member 12 are connected with the catenary 3. The moving part moves to the right, and the pushing part 15 which is fixedly arranged pushes and compresses the elastic force transmission part 9, so that the cantilever structure 1 is pushed to rotate.
As shown in fig. 16, the pushing member 15 has a first force-applying surface 151 and a second force-applying surface 152, which are mainly used for facilitating the force application, for example, the second force-applying surface 152 can be in good contact with the end surface of the elastic force-transferring member 9 (spring) in a pressing manner.
Fig. 17 shows an operation schematic diagram of an overall moving structure in a moving contact system. In the embodiment, the carrier cable 3 moves to compress the elastic force transmission piece 9, so that the cantilever structure 1 is pushed to rotate.
Fig. 18 shows an actuation schematic diagram of an overall moving structure in another moving overhead line system. In this embodiment, the catenary 3 is inserted into the sleeve 16, the catenary 3 moves to drive the pushing member 15 to move, and the pushing member 15 compresses the elastic force transmission member 9 (spring) to form a thrust to push the cantilever structure 1 to rotate.
As a preferred embodiment, the carrier cable 3 is further pulled, the elastic force transmission piece 9 is further compressed, and the sleeve piece 16 directly or indirectly transmits force to the cantilever structure 1, so as to push the cantilever structure 1 to rotate further to realize stroke compensation;
as shown in fig. 19, the force initiating end in this embodiment may be the messenger wire 3, but also may be the rotation of the cantilever structure 1, for example, the rotation of the cantilever to the left drives the sleeve 16 to rotate, the sleeve 16 directly or indirectly compresses the elastic force transmission member, the elastic force transmission member 9 is compressed to form a pushing force to act on the pushing member 15, and the pushing member 15 moves to drive the messenger wire 3 to move.
Because the moving part 1 is arranged on the cantilever structure 15 in a sliding manner, when the cantilever stops rotating, the moving part 1 can be pulled further, for example, when the most upper cantilever in a mobile overhead line system stops rotating (generally rotates to one side of a railway), at this time, a plurality of other cantilever structures 15 are not rotated in place, the moving part 1 can be pulled further, and the elastic force transmission parts 93 in the plurality of positioning devices push or pull the cantilever structures 15 to further rotate to realize stroke compensation.
The embodiment also provides an operation method of the mobile overhead line system, wherein the catenary 3 and/or the contact line 4 move relative to the cantilever structure 1 through the sliding mechanism 2;
the force transmission mechanism indirectly or directly acts the thrust or the tension formed in the moving process of the carrier cable 3 and/or the contact line 4 or the sliding mechanism 2 on the cantilever structure 1, so as to push or pull the cantilever structure 1 to rotate; or
The cantilever structure 1 rotates, and thrust or pulling force is formed by the force transmission mechanism and directly or indirectly acts on the sliding mechanism 2, so that the carrier cable 3 and/or the contact line 4 are driven to move.
In the embodiment, the carrier cable 3 is further pulled, and the pushing piece 15 and/or the elastic force transmission piece 9 pushes or pulls the cantilever structure 1 to further rotate so as to realize stroke compensation; or
The cantilever structure 1 is further rotated and the force is transferred to the messenger wire 3 by means of the push member 15 and/or the elastic force transfer member 9, thereby pushing or pulling the moving member further.
It should be added here that only in the event of a sliding movement would there be a maximum horizontal displacement of the carrier cable 3 in the horizontal direction that can be greater than the corresponding horizontal pivoting distance of the cantilever structure 1. If the carrier cable 3 is fixed on the cantilever structure 1, the horizontal moving distance of the carrier cable 3 along the horizontal direction is equal to the rotating horizontal distance of the corresponding cantilever structure 1. Just because of the relative sliding relationship, the construction error and the influence of expansion with heat and contraction with cold can be eliminated. The structure is innovated just because of the relative sliding relationship, the force transmission piece is utilized to transmit force, when the catenary 3 is pulled (the force initiating end is an external weight or a dragging mechanism pulls the catenary 3), the force generated in the moving process of the catenary 3 is transmitted to the wrist arm structure 1 to drive the wrist arm structure 1 to rotate to a working position or a non-working position; when the cantilever structure 1 rotates (when the force starting end is that the cantilever structure 1 is driven to rotate by a rotating motor or a push rod and the like), the force generated by the rotation of the cantilever structure 1 is transmitted to the moving part (the catenary cable 3) through the force-transmitting part, so that the catenary cable 3 is driven to move. The mode breaks through the traditional thinking that the catenary 3 needs to be fixedly arranged on the cantilever, and the rotation of the cantilever drives the catenary 3 to move or directly pulls the catenary 3 to move; the prior related technologies (related papers and prior published patents) are all the same, and the invention breaks through the traditional thinking that the relationship of relative movement of the carrier cable 3 and/or the contact wire 4 still exists in the moving process or the rotating process of the carrier cable 3, namely the maximum horizontal moving distance of the carrier cable 3 and/or the contact wire 4 along the horizontal direction can be larger than the rotating horizontal distance of the corresponding cantilever structure 1. The invention has the advantages that the construction error problem is effectively solved, the expansion and contraction problem of the catenary 3 is effectively solved, the situation that the catenary cannot be swung in place once from the side to the railway is caused due to the expansion and contraction of heat under the condition that the driven catenary 3 is fixedly fixed on the cantilever, and the catenary can move back and forth on the cantilever structure 1 due to the expansion and contraction of heat under the condition that the catenary is swung out of place, and the invention has the greatest highlight that in the process of swinging the whole catenary laterally, as the moving part (the catenary 3) is arranged in a sliding manner, the moving part can move back and forth on the cantilever structure 1, so that the basis is provided for further stroke compensation in place, an elastic force transmission part (such as a spring and other elastic force transmission parts) can be used, the wrist structure 1 can be further pushed or pulled to swing through the energy storage effect of the elastic force transmission part 9 to realize stroke compensation, so compared with the existing swinging situation, the scheme can perfectly solve the problem, and particularly for a long-distance, such as 1700M, mobile contact net, the catenary wire 3 and/or the contact wire 4 can be perfectly swung to one side of the railway and in place. The existing mobile contact line 4, for example, using a rigid contact line or a flexible contact line, the length of which cannot reach 1700M, or using multiple sections of mobile contact lines for splicing, is complicated in parts and construction and high in cost, and certainly or somebody needs to ask about, if a rotating motor is arranged at the root of each cantilever, the situation that the cantilever cannot swing in place indirectly can be achieved. Therefore, the invention has low failure rate, and the structure mode of the invention has the advantages of lowest failure rate, stable and reliable operation, simple and convenient operation and good swing effect.
