[0013] An embodiment of the present utility model provides a device for equidistantly moving a moving contact suspension of a moving catenary.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] In the description of the embodiments of the present invention, it should be noted that the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the embodiments of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. The terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. In addition, the terms "installation", "connection", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific situations.

[0033] As Figure 9 and Figure 10 shown, when a train in the electrified traction section of the railway enters the goods loading and unloading line, since there is a high-voltage catenary device above the freight car, loading and unloading operations cannot be carried out. Therefore, a mobile catenary device is installed to move the mobile contact suspension 7 of the catenary away from directly above the freight car. At present, most mobile catenaries use the support mechanism 3 of the mobile catenary to rotate along the line direction to move it away from directly above the railway.

[0034] Referring to Figures 11 - 15 , it is found that currently during the process of the mobile catenary using its support mechanism 3 to rotate along the line direction, the length of the wire of the mobile contact suspension 7 will change due to thermal expansion and contraction, resulting in unequal distances for the support mechanism 3 to rotate and move the mobile contact suspension 7 away from the center of the line, thus not meeting the requirements for cargo loading.

[0035] The highest temperature during catenary design is t max , and the lowest temperature is t min . Then the average temperature (temperature without offset) t p = (t max + t min ) / 2. As Figure 11 shown, when the instantaneous temperature t x at the site = t p , the mobile support mechanism 3 of the catenary does not undergo horizontal offset, that is, the support mechanism 3 is perpendicular to the railway.

[0036] Specifically, the length change δ x of the wire of the mobile contact suspension 7 = L x ρ(t x - tp ), where: L x - The distance between the support mechanism 3 and the first down-anchor post 9; ρ - The linear expansion coefficient of the wire of the moving contact suspension 7; t x -- The actual temperature at the site; t p -- The average temperature (the temperature at which the support mechanism 3 has no offset).

[0037] As Figure 12 shown, when t x > t p , the support mechanism 3 of the moving catenary deflects in the direction of the second down-anchor post 11 by a δ x value.

[0038] As Figure 13 shown, when t x < t p , the support mechanism 3 of the moving catenary deflects in the direction of the first down-anchor post 9 by a -δ x value (when δ x is negative, it means the wire shortens).

[0039] As Figure 14 shown, when t x > t p , when it is necessary to move the moving catenary to the loading position, the specific operation is as follows: The power mechanism 8 on the first down-anchor post 9 pulls the moving contact suspension 7, and the support mechanism 3 deflects in the direction of the first down-anchor post 9. The distance between every two adjacent intermediate posts 6 is a x , the extension of the wire of the moving contact suspension 7 from the first down-anchor post 9 is δ x , δ x = δ n - δ n-1 , then the length of the wire between the support mechanisms 3 of every two adjacent intermediate posts 6 is a x + δ x , so the actual distance H x by which the wire is actually moved away is smaller than the theoretically moved-away distance H by h x .

[0040] In summary, the longer the anchor section of the moving catenary and the closer the site temperature is to t max , the larger the value of h x , making the distance by which the moving catenary leaves the line unable to reach the distance for loading the freight car, affecting the loading and unloading operations.

[0041] Similarly, when t x < t p , the schematic diagram of the moving catenary moving to the loading and unloading position is as Figure 15 shown.

[0042] From Figure 14 andFigure 15 It can be seen that whether at t x > t p or at t x < t p , there is a problem that the moving catenary cannot be moved away by the designed moving distance, and the longer the anchor section length of the moving catenary, the more serious this situation is.

[0043] As Figures 1 - 8 shown, the embodiment of the present invention provides a device for moving the moving contact suspension of the moving catenary at an equal distance. The device includes a positioning frame 1, a sliding mechanism 2, a support mechanism 3, a first auxiliary wire 4, and a second auxiliary wire 5. A positioning frame 1 is respectively arranged on each intermediate pillar 6. In practical applications, a plurality of intermediate pillars 6 are provided according to the length of the required moving catenary, and the intermediate pillars 6 are used to install the support mechanism 3 and support the moving contact suspension 7.

[0044] As Figure 1 shown, a sliding mechanism 2 is respectively arranged on each positioning frame 1, and each sliding mechanism 2 can move along the length direction of the moving contact suspension 7 on the positioning frame 1. Each sliding mechanism 2 is respectively connected to the first end of the support mechanism 3 at the corresponding position, the second end of each support mechanism 3 is connected to the moving contact suspension 7, one end of the moving contact suspension 7 is connected to the first down-anchor pillar 9 through a power mechanism 8, and the other end of the moving contact suspension 7 is connected to the second down-anchor pillar 11 through a first tension compensation mechanism 10. In practical applications, the power mechanism 8 pulls the moving contact suspension 7 to drive the support mechanism 3 to rotate, so that the second end of the support mechanism 3 deflects towards the first down-anchor pillar 9, and the first tension compensation mechanism 10 provides a constant tension for the moving contact suspension 7.

[0045] In practical applications, the linear expansion coefficients of the first auxiliary wire 4 and the second auxiliary wire 5 are equal to the linear expansion coefficient of the contact wire of the moving contact suspension 7. Setting the linear expansion coefficients of the first auxiliary wire 4 and the second auxiliary wire 5 equal to the linear expansion coefficient of the contact wire of the moving contact suspension 7 can ensure that the synchronous moving distances of each sliding mechanism 2 are the same, so as to ensure that the moving distances of the first end and the second end of the support mechanism 3 generated with the change of temperature are always equal, so that the support mechanism 3 can be perpendicular to the line at any temperature. Continue to refer to Figures 1 - 6As shown in the figure, the first end of the first auxiliary cable 4 is fixedly connected to the first lower-anchoring support post 9, the middle position is fixedly connected to the upper ends of the sliding mechanisms 2 at corresponding positions respectively, and the second end is connected to the second tension compensation mechanism 12. The first end of the second auxiliary cable 5 is fixedly connected to the first lower-anchoring support post 9, the middle position is fixedly connected to the lower ends of the sliding mechanisms 2 at corresponding positions respectively, and the second end is connected to the second tension compensation mechanism 12. Specifically, the second tension compensation mechanism 12 provides a constant tension for the first auxiliary cable 4 and the second auxiliary cable 5. In practical applications, the lengths of the first auxiliary cable 4 and the second auxiliary cable 5 increase or shorten due to temperature changes, so as to drive the sliding mechanisms 2 to move along the length direction of the moving contact suspension 7 on the positioning frame 1. The movement of the sliding mechanisms 2 drives the movement of the first ends of the support mechanisms 3, so as to ensure that the support mechanisms 3 of every two adjacent intermediate support posts 6 are always parallel. This is equivalent to forming a plurality of parallelograms, and further ensures that the moving catenary is always parallel to the line center when it moves away, so as to realize the equidistant movement of the moving contact suspension 7 away from the line center.

[0046] As Figure 7 shown in the figure, the positioning frame 1 includes a vertical rod 1a, an inclined support rod 1b and two cross rods 1c. The two cross rods 1c are both parallel to the moving contact suspension 7, and the first end of each cross rod 1c is connected to the intermediate support post 6. The vertical rod 1a and the cross rod 1c are perpendicularly arranged, and the two ends of the vertical rod 1a are respectively connected to the second ends of the cross rods 1c at corresponding positions. One end of the inclined support rod 1b is connected to the intermediate support post 6, and the other end of the inclined support rod 1b is connected to the vertical rod 1a. In practical applications, the intermediate support post 6, the vertical rod 1a and the two cross rods 1c form a rectangular frame, and the inclined support rod 1b is used to improve the stability of the positioning frame 1.

[0047] Continue to refer to Figure 7 shown in the figure, the sliding mechanism 2 includes a track 21 and a sliding structure 22. Tracks 21 are respectively arranged at the upper and lower ends of the positioning frame 1, and the extending direction of the track 21 is the same as the extending direction of the moving contact suspension 7. The upper end of the sliding structure 22 is fixedly connected to the middle position of the first auxiliary cable 4, and the lower end is fixedly connected to the middle position of the second auxiliary cable 5. The sliding structure 22 is connected to the first end of the support mechanism 3, and the sliding structure 22 can move on the track 21. In practical applications, the lengths of the first auxiliary cable 4 and the second auxiliary cable 5 increase or shorten due to temperature changes, so as to drive the sliding structure 22 to move along the track 21, thereby driving the movement of the first end of the support mechanism 3.

[0048] An embodiment of the present utility model provides a device for moving the mobile contact suspension of a mobile catenary at equal intervals. The device includes a positioning frame 1, a sliding mechanism 2, a support mechanism 3, a first auxiliary cable 4, and a second auxiliary cable 5. A positioning frame 1 is respectively arranged on each intermediate pillar 6. A sliding mechanism 2 is respectively arranged on each positioning frame 1, and each sliding mechanism 2 can move along the length direction of the mobile contact suspension 7 on the positioning frame 1. Each sliding mechanism 2 is respectively connected to the first end of the support mechanism 3 at the corresponding position, the second end of each support mechanism 3 is connected to the mobile contact suspension 7, one end of the mobile contact suspension 7 is connected to the first down-anchor pillar 9 through a power mechanism 8, and the other end of the mobile contact suspension 7 is connected to the second down-anchor pillar 11 through a first tension compensation mechanism 10. The linear expansion coefficients of the first auxiliary cable 4 and the second auxiliary cable 5 are equal to the linear expansion coefficient of the contact wire of the mobile contact suspension 7. The first end of the first auxiliary cable 4 is fixedly connected to the first down-anchor pillar 9, the middle position is respectively fixedly connected to the upper ends of the sliding mechanisms 2 at the corresponding positions, and the second end is connected to the second tension compensation mechanism 12. The first end of the second auxiliary cable 5 is fixedly connected to the first down-anchor pillar 9, the middle position is respectively fixedly connected to the lower ends of the sliding mechanisms 2 at the corresponding positions, and the second end is connected to the second tension compensation mechanism 12. The positioning frame 1 includes a vertical rod 1a, an inclined support rod 1b, and two cross bars 1c. The two cross bars 1c are both parallel to the mobile contact suspension 7, and the first end of each cross bar 1c is connected to the intermediate pillar 6. The vertical rod 1a is perpendicular to the cross bar 1c, and the two ends of the vertical rod 1a are respectively connected to the second ends of the cross bars 1c at the corresponding positions. One end of the inclined support rod 1b is connected to the intermediate pillar 6, and the other end of the inclined support rod 1b is connected to the vertical rod 1a. The sliding mechanism 2 includes a track 21 and a sliding structure 22. Tracks 21 are respectively arranged at the upper and lower ends of the positioning frame 1, and the extending direction of the track 21 is the same as the extending direction of the mobile contact suspension 7. The upper end of the sliding structure 22 is fixedly connected to the middle position of the first auxiliary cable 4, and the lower end is fixedly connected to the middle position of the second auxiliary cable 5. The sliding structure 22 is connected to the first end of the support mechanism 3, and the sliding structure 22 can move on the track 21. In practical applications, the power mechanism 8 pulls the mobile contact suspension 7 to drive the support mechanism 3 to rotate, so that the second end of the support mechanism 3 deflects towards the direction of the first down-anchor pillar 9. The lengths of the first auxiliary cable 4 and the second auxiliary cable 5 change with the temperature, so as to drive the sliding mechanism 2 to move along the length direction of the mobile contact suspension 7 on the positioning frame 1. The movement of the sliding mechanism 2 drives the first end of the support mechanism 3 to move, so as to ensure that the support mechanism 3 is perpendicular to the line at any temperature, and further realize that the mobile contact suspension 7 moves away from the center of the line at equal intervals.

[0049] Such as Figure 7 And Figure 8As shown, the sliding structure 22 includes a sliding member 221, a supporting column 222 and a fixed base 223. The supporting column 222 and the track 21 are arranged vertically, and the upper and lower ends of the supporting column 222 are respectively connected to a sliding member 221. The upper end of the supporting column 222 is fixedly connected to the middle position of the first auxiliary thread 4, and the lower end is fixedly connected to the middle position of the second auxiliary thread 5. Each sliding member 221 is connected to the track 21 at a corresponding position. The fixed base 223 is arranged on the supporting column 222, and one end of the fixed base 223 away from the supporting column 222 is connected to the supporting mechanism 3. Specifically, the length of the first auxiliary thread 4 and the second auxiliary thread 5 increases or decreases due to temperature changes, so as to drive the sliding member 221 to move along the track 21, thereby driving the first end of the supporting mechanism 3 to move. In practical applications, the setting of the supporting column 222 can always keep the sliding member 221 moving smoothly, so as to avoid the sliding member 221 twisting to affect its own transmission efficiency or jamming.

[0050] Continue to refer to Figure 8 As shown, the sliding member 221 includes a sliding frame 2211 and a pulley 2212. The sliding frame 2211 is sleeved on the track 21. The upper and lower inner walls of the sliding frame 2211 are respectively provided with a pulley 2212, and each pulley 2212 is in contact with the track 21. In practical applications, the sliding frame 2211 and the pulley 2212 have simple structures and high moving efficiency. Specifically, the shape of the pulley 2212 can be U-shaped, V-shaped, rectangular, etc., and the embodiment of the utility model is not limited to this.

[0051] like Figure 1 As shown, the first tension compensation mechanism 10 includes a first sliding structure compensator 101 and a first weight 102. One end of the first sliding structure compensator 101 is connected to the movable contact suspension 7, and the other end is rotatably connected to the top of the second lower anchor pillar 11. A steel wire rope is wound around the first sliding structure compensator 101, and a first weight 102 is suspended at the free end of the steel wire rope. The first weight 102 provides tension to the movable contact suspension 7 through the first sliding structure compensator 101. In actual application, the weight of the first weight 102 provides constant tension to the movable contact suspension 7, and the height of the first weight 102 from the ground changes with the temperature.

[0052] like Figure 2 As shown, the device further includes a third lower anchor pillar 13. The third lower anchor pillar 13 is fixed between the middle pillar 6 and the second lower anchor pillar 11, and the second tension compensation mechanism 12 is arranged on the third lower anchor pillar 13. Specifically, the third lower anchor pillar 13 is arranged to install the second tension compensation mechanism 12 to avoid the second tension compensation mechanism 12 from interfering with the first tension compensation mechanism 10 on the second lower anchor pillar 11.

[0053] like Figure 1As shown in the figure, the second tension compensation mechanism 12 includes a second sliding structure compensator 121 and a second counterweight 122. The first ends of the first auxiliary wire 4 and the second auxiliary wire 5 are both connected to the first end of the second sliding structure compensator 121, and the second end of the second sliding structure compensator 121 is rotatably connected to the top of the third down-anchor post 13. A steel wire rope is wound around the second sliding structure compensator 121, and the free end of the steel wire rope is suspended with the second counterweight 122. The second counterweight 122 provides tension for the first auxiliary wire 4 and the second auxiliary wire 5 through the second sliding structure compensator 121. In practical applications, the weight of the second counterweight 122 provides a constant tension for the first auxiliary wire 4 and the second auxiliary wire 5, and the height of the second counterweight 122 from the ground will change with the change of temperature.

[0054] Continue to refer to Figure 1 As shown in the figure, the power mechanism 8 includes a winch 81 and a third sliding structure compensator 82. The winch 81 is fixed at the lower part of the first down-anchor post 9, and the winch 81 is connected to the third sliding structure compensator 82 through a steel wire rope.
