Description

Technical Field

[0001] The utility model relates to the technical field of catenary installation tools, in particular to a catenary straightening component and a straightening device. Background Art

[0002] At present, in the construction of electrified railways and subsequent upgrade and maintenance, the catenary provides electric energy for electric locomotives and is a main component of electric locomotives. The catenary wire in the catenary is in direct contact with the pantograph of the locomotive and slides at high speed. Therefore, a smooth and uniform contact between the catenary wire and the pantograph is crucial. If the catenary wire has local bending, it will cause poor contact between the catenary wire and the pantograph, resulting in unstable train operation, arcing, and even damage to on-vehicle electrical equipment and other dangerous situations.

[0003] Since the contact force between the pantograph of the locomotive and the catenary wire changes very complexly when the electric locomotive is running, usually, the contact point that causes a sudden change in the contact force between the pantograph and the catenary wire is called a contact hard point, generally referred to as a hard point.

[0004] The damage caused by hard points to the catenary and the pantograph is divided into two types. One is mechanical damage, which refers to slight bruises, scratches, etc. on the pantograph and the catenary wire; the other is arc damage, mainly caused by the off-line of the pantograph-catenary and the high-temperature arc generated instantaneously during off-line, which damages the catenary and the pantograph. The damage to the pantograph is manifested as pitting and vaporization of the pantograph head; the damage to the catenary wire is manifested as pitting, vaporization of the catenary wire, and high-temperature annealing of the catenary wire.

[0005] Therefore, hard points can cause varying degrees of damage to the contact point and the pantograph, and even affect the safe operation of the locomotive. Content of the Utility Model

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances

[0059] The contact wire straightening assembly and straightening equipment of the present utility model will be described in detail below with reference to the drawings. It should be noted that the drawings and embodiments are only used to explain the contact wire straightening assembly and straightening equipment of the present utility model and cannot be construed as a limitation of the present utility model

[0060] Figure 1 Structural schematic diagram of the contact wire straightening equipment for the embodiment of the present utility model, as Figure 1As shown in the figure, the catenary straightening device 200 of the present embodiment includes a catenary straightening assembly 100, a clamp body 210, and a driving assembly 260. Among them, the catenary straightening assembly 100 is installed in the clamp body 210. One end of the driving assembly 260 is connected to a part of the catenary straightening assembly 100 and can drive a part of the clamping members in the catenary straightening assembly 100 to move, providing power for the catenary straightening work of the catenary straightening assembly 100 on the catenary.

[0061] In an embodiment of the present invention, the driving assembly 260 is provided with a driving rod 261. One end of the driving rod 261 is connected to the second clamping member 120 of the catenary straightening assembly 100 and can drive the second clamping member 120 to move in the direction of the first clamping member 110. Thus, the first clamping member 110 and the second clamping member 120 can straighten the catenary, making the catenary return to a straight state and overcoming the influence caused by hard points on the catenary.

[0062] Among them, the driving rod 261 passes through the clamp body 210, and under the action of the driving force, the relative position between the driving rod 261 and the clamp body 210 can be adjusted or changed together during the catenary straightening process by the straightening assembly on the catenary.

[0063] In an embodiment, the clamp body 210 is connected to the driving assembly 260. A hole suitable for the driving rod 261 to pass through is provided in the clamp body 210. One end of the driving rod 261 can freely enter and exit in this hole. Thus, after one end of the driving rod 261 is connected to the second clamping member 120 of the catenary straightening assembly 100, it can drive the second clamping member 120 to move in the direction close to the first clamping member 110 or in the direction away from the first clamping member 110.

[0064] It should be noted that in the driving assembly 260 of the catenary straightening device of the present invention, the device for providing power for the driving rod 261 can be a hydraulic device, or a pneumatic device, or other mechanical transmission devices. When a hydraulic device or a pneumatic device is adopted, the driving rod 261 can be the piston rod of the hydraulic device or the pneumatic device. One end of the piston rod extending out of the hydraulic cylinder or the pneumatic cylinder is connected to the second clamping member 120. Under the action of hydraulic pressure or air pressure, the piston rod drives the second clamping member 120 to move in the direction close to the first clamping member 110 or away from the first clamping member 110.

[0065] The device for providing power for the driving rod 261 can also be a driving motor and a transmission device connected to the driving motor. The driving motor provides a rotational torque. The input end of the transmission device is connected to the output end of the driving motor and adjusts the rotational torque of the driving motor into a linear motion at the output end. When the output end of the transmission device is connected to the driving rod 261, the transmission device drives the driving rod 261 to move linearly, thereby driving the second clamping member 120 to move.

[0066] Figure 9 This is a schematic structural diagram of the relative arrangement of the first clamping member and the second clamping member of the catenary straightening assembly according to an embodiment of the present invention. As Figure 9 shown, the catenary straightening assembly 100 includes a first clamping member 110 and a second clamping member 120. During the process of straightening the catenary, the first clamping member 110 and the second clamping member 120 are arranged relatively. When the first clamping member 110 and the second clamping member 120 approach each other, the first clamping member 110 and the second clamping member 120 clamp the catenary and straighten the hard points therein. When the first clamping member 110 and the second clamping member 120 move away from each other, the first clamping member 110 and the second clamping member 120 release the catenary, completing the straightening of the hard points on the catenary.

[0067] As Figure 9 shown, in one embodiment, the driving rod 261 is connected to the first clamping member 110, driving the first clamping member 110 to move in the direction close to the second clamping member 120 to straighten the hard points of the catenary, and driving the first clamping member 110 to move in the direction away from the second clamping member 120 to release the catenary, completing the straightening work of the catenary.

[0068] In another embodiment, the driving rod 261 is connected to the second clamping member 120, driving the second clamping member 120 to move in the direction close to the first clamping member 110 to straighten the hard points of the catenary; driving the second clamping member 120 to move in the direction away from the second clamping member 120 to release the catenary, completing the straightening work of the catenary.

[0069] Among them, the first clamping member 110 or the second clamping member 120 can move in the direction indicated by the arrow.

[0070] Figure 2 This is a schematic structural diagram of the first clamping member of the catenary straightening assembly according to an embodiment of the present invention. As Figure 2 shown, the catenary straightening assembly 100 of this embodiment includes a first clamping member 110. A first groove 111 is formed by the inward depression of a part of the outer surface of the first clamping member 110. The first groove 111 can accommodate part of the catenary and form part of the straightening space.

[0071] Among them, the first groove 111 is open at both ends of the first clamping member 110, suitable for the catenary to enter or leave the first groove 111. The first groove 111 extends from one end of the first clamping member 110 to the other end, so that the first groove 111 can accommodate the catenary with hard points in the length direction of the contact point, and at the same time can straighten this part of the catenary.

[0072] As Figure 2As shown, the first groove 111 has a first arc 112 in a plane perpendicular to the threading direction of the contact wire. The arc-shaped first groove 111 is conducive to restoring the contact wire with hard points to its original state. The radius of curvature of the first arc 112 can also be set to be the same as the radius of curvature of the outer peripheral surface of the contact wire, so that the first arc 112 can play the role of a partial cavity for the part of the contact wire accommodated therein, and can improve the straightening efficiency of the contact wire.

[0073] Wherein, in a plane perpendicular to the threading direction of the contact wire, the first arc 112 of the first groove 111 and the second groove 121 jointly cover a part of the outer peripheral surface of the contact wire, and the contact wire is straightened by the clamping force generated by the mutual approach of the first clamping member 110 and the second clamping member 120.

[0074] In one embodiment, the first arc 112 of the first groove 111 and the second groove 121 jointly cover more than one-half of the outer peripheral surface area of the contact wire, so that the first groove 111 and the second groove 121 can have a larger contact area with the contact wire and have a better straightening effect.

[0075] As Figure 2 shown, in one embodiment of the present utility model, one end of the first clamping member 110 is provided with a first opening 113, and the other end is provided with a second opening 114, and the first opening 113 and the second opening 114 are located at both ends of the first groove 111 and communicate with the first groove 111. Along the threading direction of the contact wire, the extension path of the first groove 111 between the first opening 113 and the second opening 114 is arc-shaped; the first groove 111 is arc-shaped in the length direction, which is conducive to overcoming the elastic deformation of the material of the contact wire itself during the straightening process and finally restoring the contact wire to a straight state.

[0076] When a hard point area of the contact wire bends in one direction, the hard point area is placed in the straightening space formed by the first clamping member 110 and the second clamping member 120 of the contact wire straightening assembly 100. The straightening direction of the arc-shaped first groove 111 in the length direction for the contact wire is opposite to the bending direction of the contact wire. After the bending of the hard point area of the contact wire is adjusted to a straight state, under the action of the arc-shaped first groove 111, it bends in the opposite direction to a certain extent, and the bending radius is the same as the radius of curvature of the first groove 111. When the first clamping member 110 and the second clamping member 120 move in a direction away from each other and release the contact wire, due to the elastic deformation of the material of the contact wire itself, the elastic deformation generated by the material itself can offset the bending deformation of the contact wire in the first groove 111 in the opposite direction, and finally the contact wire is adjusted to a straight state.

[0077] In the straightening component 100 of the contact wire in this embodiment, the first groove 111 is set in an arc shape in the length direction. During the process of straightening the contact wire, the elastic deformation generated by the material itself is cleverly overcome. Under the technical inspiration of the present invention, the arc radius of the first groove 111 in the length direction can be adapted to the elastic modulus of the material of the contact wire, so as to achieve the purpose of accurately straightening the contact wire. That is, for contact wires of different materials, there are corresponding contact wire straightening components 100, and corresponding arc radii of the first grooves 111 of the first clamping members 110. Thus, the first clamping member 110 with a first groove 111 having a certain radius of curvature is used to straighten a contact wire of one material and accurately straighten the hard point area of the contact wire.

[0078] In one embodiment, along the extension direction of the contact wire, the radius of curvature of the first groove 111 between the first opening 113 and the second opening 114 is any value within the range of 2500 mm to 3500 mm. For example, the radius of curvature of the first groove 111 in the length extension direction is 3000 mm. The radius of curvature of the first groove 111 can also be set to values such as 2500 mm, 2600 mm, 2700 mm, 2800 mm, 2900 mm, 3100 mm, 3200 mm, 3300 mm, 3400 mm, 3500 mm, etc.

[0079] As Figure 2 shown, in one embodiment of the present invention, along the extension direction of the contact wire, the distance H1 between the first opening 113 and the second opening 114 of the first groove 111 of the first clamping member 110 is any value between 200 mm and 250 mm. Limiting the first groove 111 of the first clamping member 110 within the above length range can more efficiently straighten the hard point area of the contact wire. Because if the length of the first groove 111 is too large, it is not conducive to straightening the local area of the contact wire. If the length of the first groove 111 is too small, the first clamping member 110 cannot provide sufficient straightening force, and at the same time, higher requirements are put forward for the material hardness and strength of the contact wire straightening component 100.

[0080] Figure 3 It is a schematic structural view of another perspective of the first clamping member of the contact wire straightening component in the embodiment of the present invention. As Figure 3 shown, the first clamping member 110 is provided with a clamping structure in the direction away from the first groove 111, and this clamping structure is used to be clamped with the clamp body 210 of the contact wire straightening device 200 to fix the first clamping member 110.

[0081] As Figure 3As shown in the figure, triangular ribs are provided on both sides of the first clamping member 110. The triangular ribs extend along the length direction of the first groove 111. Thus, the clamping body 210 can fix the first clamping member 110 on both sides of the first clamping member 110, so that the first clamping member 110 and the second clamping member 120 have high stability during the process of approaching each other to clamp the contact wire.

[0082] In order to fix the first clamping member 110 on the clamping body 210, connection holes can also be provided on the side surface of the first clamping member 110. The first clamping member 110 is fixed on the clamping body 210 through the connection holes and fasteners, playing a role of stable connection.

[0083] Figure 4 This is a schematic structural diagram of the second clamping member of the contact wire straightening assembly according to an embodiment of the present invention. As Figure 4 shown, the contact wire straightening assembly 100 of this embodiment further includes a second clamping member 120. A part of the outer surface of the second clamping member 120 is recessed inward to form a second groove 121. In the working state, the second groove 121 is arranged opposite to the first groove 111 of the first clamping member 110 to form a straightening space for straightening the contact wire.

[0084] Both ends of the second groove 121 are open at both ends of the second clamping member 120, and are suitable for the contact wire to pass through the straightening space. The second groove 121 extends from one end of the second clamping member 120 to the other end. Thus, the second groove 121 and the first groove 111 can accommodate the contact wire with hard points in the length direction of the contact point, and the straightening space formed by the relatively arranged second groove 121 and the first groove 111 can straighten this part of the contact wire.

[0085] As Figure 4 shown, in an embodiment of the present invention, in a plane perpendicular to the direction in which the contact wire passes through, the second groove 121 has a second arc 122, and the second arc 122 and the first arc 112 can cover at least part of the outer peripheral surface of the contact wire.

[0086] In an embodiment of the present invention, the area of the outer peripheral surface of the contact wire covered by the first arc 112 and the second arc 122 is more than one-half of the area of the outer peripheral surface of the contact wire.

[0087] In an embodiment of the present utility model, one end of the second clamping member 120 is provided with a third opening 123, and the other end is provided with a fourth opening 124. The third opening 123 and the fourth opening 124 are located at both ends of the second groove 121 and communicate with the second groove 121. Along the threading direction of the contact wire, the extending path of the second groove 121 between the third opening 123 and the fourth opening 124 is arc-shaped; wherein, the arc of the first groove 111 matches the arc of the second groove 121 to form a uniform straightening space. In this embodiment, the uniform straightening space can straighten the contact wire continuously and smoothly without causing secondary damage to the contact wire. The uniformity of the straightening space means that the first groove 111 and the second groove 121 change continuously in their extending directions, and there is no step-like change in the entire straightening space.

[0088] It should be noted that the straightening space changes continuously in the threading direction of the contact wire. It can be uniform and consistent, forming an opening suitable for the contact wire to enter. The hard points of the contact wire can also be straightened within the straightening space.

[0089] In an embodiment of the present utility model, in any two planes perpendicular to the threading direction of the contact wire, the straightening regions formed between the first arc 112 and the second arc 122 are the same. In this embodiment, the straightening regions in the straightening space that are in contact with the contact wire are kept the same. For example, the curvature radii of the first groove 111 and the second groove 121 are the same, which can apply the same acting force to each position of the contact wire in the straightening space, facilitating the hard points on the contact wire to return to the straight state.

[0090] In an embodiment of the present utility model, along the extending direction of the contact wire, the distance H2 between the third opening 123 and the fourth opening 124 of the second groove 121 is any value between 200 mm and 250 mm, and the values can be 200 mm, 210 mm, 220 mm, 230 mm, 240 mm, 250 mm.

[0091] It should be noted that the lengths of the first groove 111 and the second groove 121 should be adapted to their curvature radii to overcome the elastic deformation of the contact wire during the straightening process.
