Description

Technical Field

[0001] This application relates to the technical field of catenary, and in particular to an auxiliary tool for catenary wire laying. Background Art

[0002] When reconstructing the German catenary of existing railways, it is necessary to replace the catenary on the top of the horizontal arm.

[0003] Currently, when replacing the catenary, a suspension pulley is hung on the horizontal arm. Then, the new catenary is temporarily strung on the suspension pulley by using a stringing car. Next, the old catenary fixed on the catenary seat at the top of the horizontal arm is disassembled. Finally, the operator fixes the new catenary on the catenary seat at the top of the horizontal arm.

[0004] In the above process of replacing the catenary, since the suspension pulley is vertically suspended at the bottom of the horizontal arm and the catenary seat is fixed at the top of the horizontal arm, when the operator fixes the new catenary on the catenary seat, it is necessary to lift the catenary upward over the horizontal arm. Due to the tension of the new catenary, the replacement of the catenary is time-consuming and laborious and there are also potential safety hazards. Utility Model Content

[0005] In order to facilitate the replacement of the catenary, this application provides an auxiliary tool for catenary wire laying.

The second fixing ring 41 includes a third half ring 411 and a fourth half ring 412. Two third connecting blocks 42 are provided and are respectively located at both ends of the third half ring 411. The third connecting block 42 is integrally formed with the third half ring 411. Two fourth connecting blocks 43 are provided and are respectively located at both ends of the fourth half ring 412. The fourth connecting block 43 is integrally formed with the fourth half ring 412. Second fixing holes are formed in both the third connecting block 42 and the fourth connecting block 43.

[0035] The fifth connecting block 44 is integrally formed with one of the third connecting blocks 42. The sixth connecting block 45 is integrally formed with one of the fourth connecting blocks 43. When the second fixing ring 41 is sleeved on the support rod 1, there is a gap between the fifth connecting block 44 and the sixth connecting block 45. Third fixing holes are formed in both the fifth connecting block 44 and the sixth connecting block 45. The connecting rod 46 is made of a bolt. The connecting rod 46 is inserted into the third fixing holes in the fifth connecting block 44 and the sixth connecting block 45, and the connecting rod 46 is fixedly connected to the fifth connecting block 44 and the sixth connecting block 45 through nuts. The hook 47 is hung on the connecting rod 46.

[0036] A suspension pulley assembly 3 is connected to the hook 47. The suspension pulley assembly 3 includes a mounting ring 31, a pulley 32, a hinge shaft, a hinge plate 33 and a torsion spring 34. The mounting ring 31 is fixedly connected to the hook 47 by welding. A notch 311 is formed in the mounting ring 31. The pulley 32 is rotatably arranged in the mounting ring 31. The pulley 32 is located at the top of the catenary support. The hinge shaft is fixedly arranged on the mounting ring 31 and is located at the notch of the notch 311. One end of the hinge plate 33 is rotatably connected to the hinge shaft. The hinge plate 33 is located at the opening of the notch 311. Two torsion springs 34 are provided and are respectively located on both sides of the hinge plate 33. The torsion springs 34 are sleeved on the hinge shaft, and the two ends of the torsion springs 34 are respectively fixedly connected to the mounting ring 31 and the hinge plate 33.

[0037] The implementation principle of an auxiliary tool for catenary wire laying in an embodiment of the present application is as follows:

[0038] During use, the operator sleeved the first fixing ring 21 on the flat wrist arm, and then inserted bolts into the first fixing holes to fix the first connecting block 22 and the second connecting block 23, so that the first half ring 211 and the second half ring 212 clamped the flat wrist arm, thereby fixing the support rod 1 on the flat wrist arm.

[0039] Then, the operator sleeved the second fixing ring 41 on the top of the support rod 1, and then passed bolts through the second fixing holes to fix the third connecting block 42 and the fourth connecting block 43, so that the third half-ring 411 and the fourth half-ring 412 clamped the support rod 1, thereby fixing the fifth connecting block 44 and the sixth connecting block 45 on the support rod 1. Then, the operator passed the connecting rod 46 through the third fixing holes on the fifth connecting block 44 and the sixth connecting block 45, and fixed the connecting rod 46 on the fifth connecting block 44 and the sixth connecting block 45 with nuts.

[0040] Finally, the operator hung the hook 47 on the connecting rod 46, thereby connecting the mounting ring 31 and the connecting rod 46, and completing the installation of the hanging wheel assembly 3 and the support rod 1.

[0041] When replacing the catenary, first use the stringing car to string the new catenary on one side of the mounting ring 31. Then, the operator pushes the hinge plate 33 to rotate it around the hinge axis, so that the notch 311 is opened. The operator then pushes the catenary into the mounting ring 31 and places it in the pulley groove 32 of the pulley 32. The hinge plate 33 rotates and resets under the action of the torsion spring 34 and closes at the notch of the notch 311. Then, the operator disassembles the old catenary on the catenary seat, and then pushes the hinge plate 33 to rotate it around the hinge axis, so that the notch 311 is opened, and the new catenary is removed from the notch 311 out of the mounting ring 31. Finally, the new catenary is fixedly installed on the catenary seat. Since the mounting ring 31 and the pulley 32 are both located on the top of the flat cross arm and the catenary seat, only the new catenary needs to be moved downward to fall into the catenary seat. Compared with the traditional catenary that needs to be lifted upward and flipped over the flat cross arm, the operation is more convenient, time-saving and labor-saving.

[0042] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
