Description

Technical Field

[0001] The present application relates to the technical field of electrified railway mobile contact network, and in particular to a simple suspended mobile contact network and an operation method thereof. Background Art

[0002] When a train in the electrified traction section of the railway enters the cargo loading and unloading line, loading and unloading operations cannot be carried out due to the high-voltage contact network device above the freight car. The installation of a mobile contact network device can move the mobile contact suspension of the mobile contact network away from the top of the freight car. The mobile contact network has two positions: one is directly above the freight car, which meets the requirements of electric locomotives to pull freight trains, such as Figure 2 As shown; the second is to move the top of the truck away to leave space for loading and unloading machinery, such as Figure 3 shown.

[0003] At present, chain-type suspended mobile contact network is often used, which includes pillars, load-bearing cables, contact wires, hanging strings and supporting devices. When the mobile contact suspension of the mobile contact network is moved away from the top of the truck, the mobile contact suspension drives the supporting device to rotate around the pillar, and the power for rotation is generally provided by a power device. The supporting device is pulled by the load-bearing cables and the contact wires during the rotation process. It can be seen that the structure of the chain-type suspended mobile contact network is relatively complex, resulting in high investment, construction and operation costs.

[0004] When a simple suspended mobile contact network is used instead of a chain-type suspended mobile contact network, if only the mobile contact suspension of the contact line is used, during the actual operation, the supporting device will only be pulled by the contact line, resulting in an unbalanced force, thereby causing the supporting device to be subjected to a torsional torque in the vertical direction, affecting the effect of the supporting device rotating around the supporting column.

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] In the description of the embodiments of the present application, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limitations on the present application. The terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, the terms "installed", "connected", and "connected" 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 a direct connection, or it can be indirectly connected through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0043] In the prior art, chain-type suspended mobile contact networks are often used, such as Figure 1-3 As shown, the chain-type suspended movable contact network includes a first anchor support 8, a second anchor support 105, a supporting column 2, a load-bearing cable 107, a contact wire 3 and a suspension string 106.

[0044] like Figure 2As shown, when the chain-type suspended mobile contact network is in the position for traction by an electric locomotive, one end of the chain-type suspension is fixedly connected to the second lower anchor pillar 105 through a winch, and the other end of the chain-type suspension is connected to the first lower anchor pillar 8 through a weight 71. The weight of the weight 71 can apply a prescribed constant tension to the chain-type suspension, thereby compensating for the length change of the mobile contact suspension caused by thermal expansion and contraction due to temperature changes, so that the contact line 3 always remains in a straightened state.

[0045] like Figure 3 As shown, when the chain-type suspended mobile contact network is in the cargo loading position, the winch pulls the chain-type mobile contact suspension toward the second lower anchor pillar 105, and the support device 1 also deflects toward the second lower anchor pillar 105, so that the mobile contact network leaves the top of the railway, thereby making room for mechanical equipment for loading cargo.

[0046] However, the mobile contact network device itself is a relatively complex device to operate. The use of chain-type suspension inevitably requires the addition of components such as load-bearing cables 107, suspension strings 106, electrical connections and tension compensation devices 7, which makes routine maintenance difficult, increases investment, construction and operating costs, and increases the probability of equipment failure.

[0047] like Figure 4 and Figure 5 As shown, when the chain-type suspended mobile contact network is in the cargo loading position, the winch pulls the contact wire 3 and the load-bearing cable 107 toward the second anchor support 105, wherein the first end of the support device 1 and the second end of the support device 1 are respectively subjected to the tension F of the contact wire 3 and the load-bearing cable 107. c and F j , during the rotation of the support device 1 around the support column 2, F C =F j If a simple suspended mobile contact network is used instead of a chain-type suspended mobile contact network, the support device 1 in the simple suspension is only subjected to the tension of the contact wire 3, which will cause the support device 1 to be subjected to a torsional moment in the vertical direction, thereby affecting the deflection of the mobile contact network.

[0048] The embodiment of the present application solves the problem in the prior art that when the contact network moves, the support device 1 is subjected to a torsional moment in the vertical direction, thereby affecting the moving effect of the contact network, by providing a simple suspension mobile contact network and an operation method. The force at the connection between the support device 1 and the mobile contact suspension is equal, the torsional moment in the vertical direction is avoided, and the structure of the mobile contact suspension is simplified, saving investment, construction and operation costs.

[0049] The embodiment of the present invention provides a simple suspended mobile contact network, such as Figure 6-8As shown, it includes a supporting device 1, a supporting column 2, a contact line 3, a first sling 4, a second sling 5, a power device 6 and a tension compensation device 7; one end of the contact line 3 is connected to the power device 6, and the other end of the contact line 3 is connected to the tension compensation device 7; the first end of the supporting device 1 is connected to the contact line 3, and the third end of the supporting device 1 rotates with the supporting 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 supporting 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 line 3; the first sling 4, the supporting device 1 and the contact line 3 form a triangular structure; the second sling 5, the supporting device 1 and the contact line 3 form a triangular structure.

[0050] 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 pulling force can be applied to one end of the contact wire 3, and the pulling 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 force on the first end of the support device 1 and the second end of the support device 1, thereby avoiding the support device 1 being subjected to a torsional torque in the vertical direction and affecting the deflection of the mobile contact network toward the second lower anchor pillar 105.

[0051] Exemplarily, the second sling 5 is rotatably connected to the second end of the supporting device 1, and the second sling 5, the supporting device 1 and the contact wire 3 form a right triangle. When the simply suspended mobile contact network moves to the position when being pulled by an electric locomotive, the power device 6 rotates in the opposite direction, thereby releasing the contact wire 3, so that the contact wire 3 rotates around the supporting column 2 toward the first lower anchor pillar 8 under the action of the tension compensation device 7. The tension compensation device 7 applies a pulling force to the contact wire 3, and this pulling force can be transmitted to the second end of the supporting device 1 through the second sling 5, so as to achieve the purpose of equal force on the first end of the supporting device 1 and the second end of the supporting device 1, thereby avoiding the supporting device 1 being subjected to a torsional moment in the vertical direction and affecting the deflection of the mobile contact network toward the first lower anchor pillar 8.

[0052] In the present application embodiment, Figure 6-8 As shown, it also includes a first anchoring pillar 8; the tension compensation device 7 includes a weight 71, a first pulley compensator 72 and a first steel wire rope 73; the other end of the contact line 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 anchoring pillar 8; the first pulley compensator 72 is wound with a first steel wire rope 73, and the free end of the first steel wire rope 73 is connected with a weight 71.

[0053] Exemplarily, the weight of the weight 71 can apply a prescribed constant tension to the contact wire 3, thereby compensating for the change in length of the contact wire 3 caused by thermal expansion and contraction due to temperature changes, so that the contact wire 3 always remains in a straightened state.

[0054] Exemplarily, when the simply suspended mobile contact network moves to the position when being pulled by an electric locomotive, the power unit 6 rotates in the opposite direction, thereby releasing the contact line 3, so that the contact line 3 rotates around the support column 2 toward the first lower anchor column 8 under the action of the gravity of the weight 71. The weight 71 applies a pulling force to the first pulley compensator 72, and this pulling force can cause the first pulley compensator 72 to rotate, thereby pulling the contact line 3 toward the first lower anchor column 8. This pulling force can be transmitted to the second end of the support device 1 through the second sling 5, so as to achieve the purpose of equal force on the first end of the support device 1 and the second end of the support device 1, thereby avoiding the support device 1 from being subjected to a torsional torque in the vertical direction, and ensuring the smooth deflection of the mobile contact network toward the first lower anchor column 8.

[0055] In the present application embodiment, Figure 6-8 As shown, it also includes a second anchor pillar 105; the power device 6 includes a driving member 61, a second pulley compensator 62 and a second steel wire rope 63; one end of the contact line 3 is connected to the second pulley compensator 62, and the second pulley compensator 62 is rotatably connected to the second anchor pillar 105; a second steel wire rope 63 is wound around the second pulley compensator 62, and the free end of the second steel wire rope 63 is connected to the power device 6.

[0056] Exemplarily, the driving member 61 can be a winch or other power element; when the simply suspended mobile contact network moves to the cargo loading position, the second pulley compensator 62 can be rotated under the action of the traction force of the winch, thereby pulling the contact line 3 toward the second lower anchor pillar 105, and the tension on the contact line 3 is transmitted to the second end of the support device 1 through the first sling 4 connected to the contact line 3, so as to achieve the purpose of equal force on the first end of the support device 1 and the second end of the support device 1, thereby avoiding the support device 1 from being subjected to a torsional torque in the vertical direction, and ensuring the smooth deflection of the mobile contact network toward the second lower anchor pillar 105.

[0057] In the present application embodiment, Fig.10 As shown, a positioning wire clamp 9 is also included; the first end of the supporting device 1 is connected to the contact wire 3 via the positioning wire clamp 9.

[0058] Exemplarily, one end of the positioning wire clamp 9 is fixedly connected to the contact wire 3 , and the other end of the positioning wire clamp 9 is rotatably connected to the first end of the supporting device 1 .

[0059] In the present application embodiment, Figure 8As shown, the support device 1 includes a support column 11, two rotating wrist arms 12, two rod insulators 13 and two rotating wrist arm bases 14; one end of the support column 11 is connected to the contact wire 3, and one end of the first sling 4 and one end of the second sling 5 are both connected to the other end of the support column 11; one end of the two rotating wrist arms 12 are connected to the support column 11, and the other ends of the two rotating wrist arms 12 are respectively connected to one end of the two rod insulators 13; the other ends of the two rod insulators 13 are respectively connected to the two rotating wrist arm bases 14, and the two rotating wrist arm bases 14 are both rotatably connected to the support column 2.

[0060] Exemplarily, one end of the positioning wire clamp 9 is fixedly connected to the contact wire 3 , the other end of the positioning wire clamp 9 is rotatably connected to one end of the support column 11 , and the other end of the support column 11 is rotatably connected to the sling fixing seat 10 .

[0061] In the present application embodiment, Fig.10 As shown, it also includes a sling fixing seat 10, a first sling wire clamp 101 and a second sling wire clamp 102; one end of the first sling 4 is connected to the sling fixing seat 10, and the other end of the first sling 4 is connected to the first sling wire clamp 101, and the first sling wire clamp 101 is connected to the contact wire 3; one end of the second sling 5 is connected to the sling fixing seat 10, and the other end of the second sling 5 is connected to the second sling wire clamp 102, and the second sling wire clamp 102 is connected to the contact wire 3; the sling fixing seat 10 is rotatably connected to the support column 11.

[0062] Exemplarily, the first sling 4 and the second sling 5 are both fixedly connected to the sling fixing seat 10, and the sling fixing seat 10 is rotatably connected to the support column 11, thereby ensuring that the first sling 4 and the second sling 5 are always parallel to the contact line 3 when the support device 1 rotates.

[0063] In the present application embodiment, Fig.10 As shown, the sling assembly also includes a first joint clamp 103 and a second joint clamp 104; the first joint clamp 103 is further connected between the first sling 4 and the first sling clamp 101, and the second joint clamp 104 is further connected between the second sling 5 and the second sling clamp 102.

[0064] In the present application embodiment, Figure 8 and Fig.10 As shown, the first sling 4 and the second sling 5 are symmetrically arranged relative to the supporting device 1 .

[0065] Exemplarily, the first sling 4, the second sling 5 and the contact line 3 form an isosceles triangle.

[0066] The embodiment of the present invention provides a simple method for operating a suspended mobile contact network. Figure 6-13As shown, the operation method is applicable to a simple suspended mobile contact network, and the steps are as follows: control the power device 6 to apply force to one end of the contact line 3; drive the first end of the support device 1 to rotate around the support column 2; drive the second end of the support device 1 to rotate around the support column 2 synchronously with the first end of the support device 1; the tension compensation device 7 applies a constant tension to the other end of the contact line 3.

[0067] Exemplarily, under the traction force of the power device 6, a pulling force can be applied to one end of the contact line 3, and the contact line 3 can drive the first end of the support device 1 to rotate, and then the pulling force on the contact line 3 is transmitted to the second end of the support device 1 through the first sling 4 connected to the contact line 3, so that the first end of the support device 1 and the second end of the support device 1 are subjected to equal forces, thereby achieving synchronous rotation of the first end of the support device 1 and the second end of the support device 1; the weight of the weight 71 can apply a specified constant tension to the contact line 3, thereby compensating for the change in length of the contact line 3 caused by thermal expansion and contraction caused by temperature changes, so that the contact line 3 always remains in a straightened state.

[0068] In the present application embodiment, Fig. 9 As shown, the second end of the supporting device 1 is driven to rotate synchronously with the first end of the supporting device 1 around the supporting column 2;

[0069] The force on the first sling 4 along the length direction of the first sling 4 is F1, and its formula is:

[0070] F1=F j ·cosβ;

[0071] The force on the other end of the support column 11 along the direction of the contact line 3 is F2, and the formula is:

[0072]

[0073] The force on the other end of the support column 11 in the vertical direction of the first sling 4 is F3, and the formula is:

[0074]

[0075] Among them, F j is the force magnitude at one end of the contact line 3, β is the angle between the first sling 4 and the contact line 3;

[0076] The magnitude of the force applied to one end of the support column 11 in the length direction of the contact line 3 is equal to the magnitude of the force applied to the other end of the support column 11 in the length direction of the contact line 3 .

[0077] For example, the tension on the contact line 3 can be transmitted to the second end of the support device 1 through the first sling 4, so that the force F on the first end of the support device 1 is jThe force F2 at the second end of the support device 1 is equal to the force F2, which prevents the support device 1 from being subjected to a vertical torsional moment during the rotation process, thereby ensuring the smooth movement of the support device 1.

[0078] Exemplarily, when the simply suspended mobile contact network moves to the position for traction by an electric locomotive, the tension on the contact line 3 can be transmitted to the second end of the support device 1 through the second sling 5, thereby achieving equality of the force on the first end of the support device 1 and the force on the second end of the support device 1, thereby avoiding vertical torsional torque on the support device 1 during rotation and ensuring smooth movement of the support device 1.

[0079] The present application embodiment provides a simple suspension mobile contact network and operation method, and its working principle is as follows:

[0080] In the present application, a pulling force is applied to one end of the contact wire 3 through a power device 6, and the contact wire 3 drives the support device 1 to move around the support column 2 toward the second lower anchor pillar 105. During the movement, the force on the contact wire 3 is transmitted to the second end of the support device 1 by the first sling 4, and the first end of the support device 1 is subjected to the pulling force of the contact wire 3, so that the force on the first end of the support device 1 is equal to the force on 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 during the rotation process, and ensuring the smooth movement of the support device 1.
