Description
Technical Field
[0001] This application relates to the technical field of electrified railway mobile catenary, and particularly relates to a simple suspension mobile catenary sling device. Background Art
[0002] When a train in an electrified traction section of a railway enters a goods loading and unloading line, since there is a high-voltage catenary device above the freight car, the loading and unloading operations cannot be carried out. Installing a mobile catenary device can move the mobile contact suspension of the mobile catenary away from directly above the freight car. The mobile catenary has two positions: one is directly above the freight car to meet the requirement of an electric locomotive pulling a freight train; the other is to move away from directly above the freight car to leave space for loading machinery to load goods.
[0003] Currently, a catenary suspension mobile catenary is often adopted, which includes a pillar, a carrier cable, a contact wire, a suspension wire and a support device. When moving the mobile contact suspension of the mobile catenary away from directly above the freight car, the mobile contact suspension drives the support device to rotate around the pillar, and generally a power device provides the power for rotation. The support device is respectively subjected to the pulling forces of the carrier cable and the contact wire during the rotation process. It can be seen that the structure of the catenary suspension mobile catenary is relatively complex, resulting in higher investment, construction and operation costs.
[0004] When using a simple suspension mobile catenary to replace the catenary suspension mobile catenary, if only the mobile contact suspension of the contact wire is adopted, in the actual operation process, the support device will only be subjected to the pulling force of the contact wire, resulting in unbalanced force on it, so that the support device is subjected to a torsional moment in the vertical direction, affecting the rotation effect of the support device around the support column.

It realizes equal force at the connection between the support device and the mobile contact suspension, avoids generating a torsional moment in the vertical direction, simplifies the structure of the mobile contact suspension, and saves investment, construction and operation costs.

[0025] An embodiment of the present invention provides a simple suspension mobile catenary sling device, as Figures 1-7 shown, which includes a support device 1, a support column 2, a contact wire 3, a first sling 4, a second sling 5, a power device 6, and a tension compensation device 7; one end of the contact wire 3 is connected to the power device 6, and the other end of the contact wire 3 is connected to the tension compensation device 7; the first end of the support device 1 is connected to the contact wire 3, and the third end of the support device 1 rotates with the support column 2; one end of the first sling 4 and one end of the second sling 5 are both connected to the second end of the support device 1, and the other end of the first sling 4 and the other end of the second sling 5 are both connected to the contact wire 3; the first sling 4, the support device 1, and the contact wire 3 enclose a triangular structure; the second sling 5, the support device 1, and the contact wire 3 enclose a triangular structure.
[0026] Exemplarily, the contact wire 3 can be used for an electric locomotive to obtain current through a pantograph. The first sling 4 is rotatably connected to the second end of the support device 1; the first sling 4, the support device 1, and the contact wire 3 form a right triangle. Under the traction force of the power device 6, a tensile force can be applied to one end of the contact wire 3, and the tensile force on the contact wire 3 is transmitted to the second end of the support device 1 through the first sling 4 connected to the contact wire 3, so as to achieve the purpose of equal forces on the first end and the second end of the support device 1, thereby avoiding the support device 1 from being affected by a torsional moment in the vertical direction and affecting the deflection of the mobile catenary towards the second down-anchor post 105.
[0027] Exemplarily, the second sling 5 is rotatably connected to the second end of the support device 1. The second sling 5, the support device 1, and the contact wire 3 form a right triangle. When the simple suspension mobile catenary moves in position during traction towards the electric locomotive, the power device 6 rotates in the opposite direction, thereby being able to release the contact wire 3, enabling the contact wire 3 to rotate around the support column 2 towards the first down-anchor post 8 under the action of the tension compensation device 7. The tension compensation device 7 gives the contact wire 3 a pulling force, and this pulling force can be transmitted to the second end of the support device 1 through the second sling 5, achieving the purpose of equal forces on the first end and the second end of the support device 1, thereby preventing the support device 1 from being affected by a torsional moment in the vertical direction and influencing the deflection of the mobile catenary towards the first down-anchor post 8.
[0028] In the embodiment of the present application, as Figures 1-7 shown, it further includes a first down-anchor post 8; the tension compensation device 7 includes a counterweight 71, a first pulley compensator 72, and a first steel wire rope 73; the other end of the contact wire 3 is connected to the first pulley compensator 72, and the other end of the first pulley compensator 72 is rotatably connected to the first down-anchor post 8; the first steel wire rope 73 is wound around the first pulley compensator 72, and the free end of the first steel wire rope 73 is connected to the counterweight 71.
[0029] Exemplarily, the weight of the counterweight 71 can apply a specified constant tension to the contact wire 3, thereby compensating for the length change of the contact wire 3 caused by thermal expansion and contraction due to temperature changes, enabling the contact wire 3 to always remain in a straight state.
[0030] Exemplarily, when the simple suspension mobile catenary moves in position during traction towards the electric locomotive, the power device 6 rotates in the opposite direction, thereby being able to release the contact wire 3, enabling the contact wire 3 to rotate around the support column 2 towards the first down-anchor post 8 under the action of the gravity of the counterweight 71. The counterweight 71 gives the first pulley compensator 72 a pulling force, and this pulling force can cause the first pulley compensator 72 to rotate, thereby pulling the contact wire 3 towards the direction close to the first down-anchor post 8. This pulling force can be transmitted to the second end of the support device 1 through the second sling 5, achieving the purpose of equal forces on the first end and the second end of the support device 1, thereby preventing the support device 1 from being affected by a torsional moment in the vertical direction and ensuring the smooth deflection of the mobile catenary towards the first down-anchor post 8.

[0032] Exemplarily, the driving member 61 can be a winch or other power element; when the simple suspension moving catenary moves towards the cargo loading position, under the action of the traction force of the winch, the second pulley compensator 62 can be rotated, so as to pull the contact wire 3 towards the direction close to the second down-anchor post 105, and the tension on the contact wire 3 is transmitted to the second end of the support device 1 through the first sling 4 connected to the contact wire 3, achieving the purpose of equal stress on the first end and the second end of the support device 1, thereby avoiding the support device 1 from being subjected to a torsional moment in the vertical direction and ensuring the smooth deflection of the moving catenary towards the second down-anchor post 105.
