Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for the installation of railway catenary droppers, specifically relating to an auxiliary installation device for replacing droppers in a double-contact-wire catenary. Background Technology

[0002] The dropper is an important component of the overhead contact system of high-speed railways. Its function is to suspend the contact wire from the catenary. As the economic artery of my country, the railway is of great significance to the country's development. In the catenary suspension, the contact wire is suspended from the catenary by the integral dropper. After the contact suspension is erected, the contact wire, the catenary, and the integral dropper located between the contact wire and the catenary, which plays a suspension role, all have a certain tension.

[0003] Currently, in existing technologies, droppers are mostly fixed and positioned using clamps, making it inconvenient for them to move on the surface of the contact wire and catenary, and also making them difficult to replace. This reduces the practicality of the equipment to some extent. Furthermore, droppers need to be kept vertical during installation to ensure the position of the contact wire, but existing droppers make it difficult to immediately check whether the droppers are vertical, which may affect the installation effect and further reduce the practicality of the equipment.

[0004] Therefore, how to provide a device to assist in the installation of droppers is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides an auxiliary installation device for replacing the dropper of a double contact wire contact network, which can assist in the installation or replacement of the dropper and ensure the sag of the dropper installation.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an auxiliary installation device for replacing the dropper of a double contact wire contact network, comprising:

[0007] Telescopic rod, which is vertically located between the catenary cable and the contact wire;

[0008] The clamping and positioning mechanism has two sets, which are respectively located at both ends of the telescopic rod. The two sets of clamping and positioning mechanisms are respectively connected to the catenary and the contact wire.

[0009] A suspension rope sag detection component is connected to one side of the clamping and positioning mechanism at the top of the telescopic rod. The suspension rope sag detection component is used to assist in detecting the sag of the telescopic rod and the installation dropper.

[0010] The beneficial effects of this utility model are: the connection and positioning between the catenary and the contact network are completed by relying on the telescopic rod and the clamping and positioning mechanism. The sag of the telescopic rod is judged by the suspension rope sag detection component. First, the sag of the telescopic rod is ensured, which directly affects the distance parameter between the catenary and the contact network. When installing the dropper, the telescopic rod is used as a reference to ensure the sag of the dropper. The catenary and the contact network are positioned by this auxiliary equipment, which also facilitates the subsequent installation and fixing of the dropper to the catenary and the contact network.

[0011] Preferably, the telescopic rod includes a support rod and a threaded rod. The support rod is a hollow rod with a thread on the inner side of its top end. The threaded rod is threaded into the interior of the support rod. The two sets of clamping and positioning mechanisms are located at the ends of the support rod and the threaded rod that are far apart from each other.

[0012] The resulting technical effect is that the telescopic rod, consisting of a support rod and a threaded rod, can be extended and retracted to adjust its length, thus adapting to the auxiliary installation of different types of droppers.

[0013] Preferably, the bottom end of the threaded rod is provided with a protruding limiting plate, the limiting plate is slidably connected to the inner side of the support rod, and the inner side of the support rod near the top end is provided with a locking step to prevent the limiting plate from falling out.

[0014] The resulting technical effect is that the limiting plate can prevent the threaded rod from separating from the support rod, and there is a maximum adjustment stroke limit.

[0015] Preferably, the clamping and positioning mechanism at the top of the threaded rod is fixedly connected to the top of the threaded rod, and the clamping and positioning mechanism at the bottom of the support rod is rotatably connected to the support rod.

[0016] The resulting technical effect is that the top of the threaded rod is fixedly connected to the clamping and positioning mechanism on the near side, and the bottom of the support rod is rotatably connected to the clamping and positioning mechanism on the near side. The purpose is to allow the support rod to be rotated to adjust the length of the telescopic rod. Specifically, the support rod can be rotatably connected to the clamping and positioning mechanism on the near side through a transition bearing.

[0017] Preferably, the clamping and positioning mechanism includes a connecting plate, an ear seat, a rotating rod, a pulley, a clamping plate, and a clamping plate tightening thread component. The connecting plate is connected to the end of the corresponding telescopic rod. The ear seat is fixed to the side of the connecting plate away from the telescopic rod. The ear seat has lugs on both sides. The rotating rod is rotatably connected to the ear seat and passes through the lugs on both sides. The pulley is fixedly connected to the rotating rod and located inside the lugs. The clamping plate tightening thread component is threaded to the connecting plate. The clamping plate is rotatably connected to the end of the clamping plate tightening thread component. The clamping plate, together with the pulley on the adjacent side, clamps the catenary cable or contact wire.

[0018] The resulting technical effect is that the clamping and positioning mechanism achieves clamping and limiting by the cooperation of pulleys and clamping plates. When the distance between the clamping plate and the pulley is slightly loosened, the device can slide on the catenary and the contact wire by the pulley. The clamping plate is adjusted by the clamping plate tension thread.

[0019] Preferably, the inner side of the ear seat is provided with a groove, the rotating rod passes through the side wall of the groove, a brake wheel is fixed in the section of the rotating rod located in the groove, a tightening bolt is threaded on the ear seat, the end of the tightening bolt passes through the side wall of the groove and abuts against the brake wheel, and the brake wheel rotates synchronously with the pulley on the rotating rod.

[0020] The resulting technical effect is that the lug is the basis for the rotation of the rotating rod, the brake wheel is used to control the rotation of the rotating rod and the pulley, and when the brake wheel is locked, the device cannot be easily moved on the catenary and the contact wire.

[0021] Preferably, the clamping plate is a long, arc-shaped plate, and the inner wall of the clamping plate has a contact arc surface adapted to the outer contour of the catenary or the contact wire.

[0022] The resulting technical effect is that when the pulley is locked and the clamping plate approaches the pulley to complete the clamping and fixing of the catenary and the contact wire, the position of the device is limited.

[0023] Preferably, the suspension rope sag detection component includes a support plate, a hanging rod, a connecting rope, and a plumb bob. The support plate is fixed to a clamping and positioning mechanism at the top of the telescopic rod. A groove is provided on one side wall of the support plate, and threaded holes are provided on both sides of the groove. The hanging rod is connected to the threaded holes, the connecting rope is connected to the hanging rod, and the plumb bob is fixed to the bottom end of the connecting rope. The sag status of the telescopic rod is fed back by the parallelism between the connecting rope and the telescopic rod.

[0024] The resulting technical effect is that the plumb bob and connecting rope are used to assist in detecting the sag of the telescopic rod.

[0025] Preferably, a roller is connected to the hanging rod, the roller is adapted to be located in the groove, and the top end of the connecting rope is fixedly connected to the outer wall of the roller.

[0026] The resulting technical effect is that the connection between the roller and the hanging rod facilitates the subsequent disassembly of the connecting rope and the plumb bob, making it easier to use. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] See appendix to this utility model Figures 1 to 6 According to an embodiment of the present invention, an auxiliary installation device for replacing the dropper of a double contact wire contact network includes:

[0036] Telescopic rod 1 is located vertically between the catenary and the contact wire, and its length can be adjusted according to the required spacing between the catenary and the contact wire.

[0037] The clamping and positioning mechanism 2 has two sets, which are located at both ends of the telescopic rod 1. The two sets of clamping and positioning mechanisms 2 are respectively connected to the catenary and the contact wire. The clamping and positioning mechanism can slide on the catenary and the contact wire, or it can restrict its position.

[0038] The suspension rope sag detection component 3 is connected to the clamping and positioning mechanism at the top of the telescopic rod 1. The suspension rope sag detection component 3 is used to assist in detecting the sag of the telescopic rod 1 and the installation suspension cable.

[0039] In use, the auxiliary device can be adjusted to slide between the catenary and the contact wire. This device can ensure the sag of the dropper installation, thereby ensuring the positional accuracy of the contact wire and the smoothness of the sliding between the train and the contact wire.

[0040] In other embodiments, the telescopic rod 1 includes a support rod 11 and a threaded rod 12. The support rod 11 is a hollow rod with a thread on the inner side of its top end. The threaded rod 12 is threaded into the inside of the support rod 11. Two sets of clamping and positioning mechanisms 2 are located at the ends of the support rod 11 and the threaded rod 12 that are far apart from each other. The length of the telescopic rod can be adjusted to adapt to different dropper installation requirements.

[0041] In some other specific embodiments, the bottom end of the threaded rod 12 is provided with a protruding limiting plate 13. The limiting plate 13 is slidably connected to the inner side of the support rod 11. The inner side of the support rod 11 near the top end is provided with a locking step 14 to prevent the limiting plate from falling out, so as to avoid the threaded rod from falling out during adjustment. The sliding connection between the limiting plate and the inner side wall of the support rod can also ensure the axial stability of the telescopic rod and prevent it from shaking.

[0042] In some other embodiments, the clamping and positioning mechanism 2 at the top of the threaded rod 12 is fixedly connected to the top of the threaded rod, and the clamping and positioning mechanism 2 at the bottom of the support rod 11 is rotatably connected to the support rod 11. Specifically, it can be connected by bearings to ensure that the telescopic rod can be smoothly adjusted in length.

[0043] In some other specific embodiments, the clamping and positioning mechanism 2 includes a connecting plate 21, an ear seat 22, a rotating rod 23, a pulley 24, a clamping plate 25, and a clamping plate tightening threaded component 26. The connecting plate 21 is connected to the end of the corresponding telescopic rod 1. The ear seat 22 is fixed on the side of the connecting plate 21 away from the telescopic rod. The ear seat 22 has ears 221 on both sides. The rotating rod 23 is rotatably connected to the ear seat 22 and passes through the ears on both sides. The pulley 24 is fixedly connected to the rotating rod 23 and is located inside the ears 221. The clamping plate tightening threaded component 26 is threadedly connected to the connecting plate 21. The clamping plate 25 is rotatably connected to the end of the clamping plate tightening threaded component 26. The purpose is to change only the distance between the clamping plate and the pulley when the clamping plate threaded component is rotated. The clamping plate 25, together with the pulley 24 on the closer side, clamps the catenary or contact wire.

[0044] In some other embodiments, the inner side of the ear seat 22 is provided with a cavity, the rotating rod 23 passes through the side wall of the cavity, and a brake wheel 27 is fixed in the section of the rotating rod 23 located in the cavity. A tightening bolt 28 is threaded onto the ear seat 22, and the end of the tightening bolt 28 passes through the side wall of the cavity and abuts against the brake wheel 27. The brake wheel 27 rotates synchronously with the pulley 24 on the rotating rod 23, and the rotation of the pulley is limited by limiting the brake wheel.

[0045] In other embodiments, the clamping plate 25 is a long, arc-shaped plate, and the inner wall of the clamping plate 25 has a contact arc surface adapted to the outer contour of the catenary or the contact wire.

[0046] In some other embodiments, the suspension rope sag detection component 3 includes a support plate 31, a hanging rod 32, a connecting rope 33, and a plumb bob 34. The support plate 31 is fixed to the clamping and positioning mechanism at the top of the telescopic rod, specifically fixed to one side of the connecting plate 21. A groove 35 is provided on one side wall of the support plate 31, and threaded holes are provided on both sides of the groove 35. One of the threaded holes penetrates the side wall of the support plate 31. The hanging rod 32 is connected in the threaded hole, and the connecting rope 33 is connected to the hanging rod 32. The plumb bob 34 is fixed to the bottom end of the connecting rope 33. The sag status of the telescopic rod 1 is fed back by the parallelism between the connecting rope 33 and the telescopic rod.

[0047] To improve the ease of disassembly of the connecting rope 33 and the plumb bob 34, a roller 36 is rotatably connected to the hanging rod 32. The roller 36 is adapted to be located in the groove 35, and the axial dimension of the roller corresponds to the axial dimension of the groove. The top end of the connecting rope 33 is fixedly connected to the outer wall of the roller 36. This can prevent the connecting rope from shifting and also allows for quick disassembly of the connecting rope and the plumb bob.

[0048] When using this product, first install clamping and positioning mechanisms at the top and bottom of the telescopic rod. The clamping and positioning mechanism 2 at the top is fixedly connected to the threaded rod 12, and the clamping and positioning mechanism 2 at the bottom is rotatably connected to the support rod 11. The outer surfaces of the two sets of pulleys 24 on the top clamping and positioning mechanism are in contact with the outer surface of the double-bearing cable. Then, assemble the connecting rope 33 and the plumb bob 34 on one side of the mechanism. At this time, the connecting rope 33 can be driven to hang down naturally by the weight of the plumb bob 34. The verticality of the equipment can be initially judged by whether the connecting rope 33 is aligned with the telescopic rod.

[0049] Then, adjust the length of the telescopic rod so that the outer surfaces of the two sets of pulleys 24 on the bottom clamping and positioning mechanism are in contact with the outer surfaces of the double contact lines. Next, maintain the perpendicularity of the support rod 11 and the threaded rod 12, and move the equipment to a suitable position by rolling the four sets of pulleys 24. After the final adjustment of the equipment, rotate the tightening bolt 28 to make it press against the outer surface of the brake wheel 27, restrict the rotation of the rotating rod 23 and the pulleys 24, and rotate the four sets of clamping plate tightening threaded parts 26 in sequence to move the four sets of clamping plates 25 so that the inner wall surfaces of the four sets of clamping plates 25 press against the outer surfaces of the double contact lines and the double bearing cables respectively, thereby finally positioning the equipment. Then, continue to rotate the support rod 11 to adjust the length between the support rod 11 and the threaded rod 12, so as to adjust the spacing between the double contact lines and the double bearing cables according to actual needs, and then install the droppers. After the droppers are installed, the entire device can be disassembled.

[0050] This invention allows for adjustment of the length of the telescopic rods by rotating the support rod, enabling the outer surfaces of the four sets of pulleys to respectively conform to the outer surfaces of the double contact lines and double support cables. Simultaneously, the support rod and threaded rod allow for adjustment of the spacing between the double contact lines and double support cables according to actual needs. The rolling of the pulleys facilitates movement of the equipment on the surfaces of the contact lines and support cables. Rotating the clamping plate and tightening the threaded parts moves the clamping plate, causing its inner wall surface to press against the outer surfaces of the contact lines and support cables. Subsequently, rotating the tightening bolt and restricting the brake wheel achieves rotational positioning of the rotating rod and pulleys, thus completing the positioning of the equipment.

[0051] The weight of the plumb bob causes the connecting rope to hang down naturally. By observing whether the connecting rope is aligned with the support rod and the threaded rod, it can be determined whether the telescopic rod is vertical, which provides a reference for the installation of the dropper and improves the installation efficiency of the dropper to a certain extent.

[0052] The apparatus and methods disclosed in the embodiments are described simply because they correspond to the methods disclosed in the embodiments. For relevant details, please refer to the method section.

[0053] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
