Description

Technical Field

[0001] The present disclosure relates to the technical field of catenary production equipment, and particularly to a catenary prefabrication device. Background Art

[0002] With the rapid development of China's railway technology, higher and newer requirements have been put forward for railway process quality and standards. In an electrified railway line, the catenary is an important part to ensure the normal operation of the railway. The catenary is connected to the electrified railway power supply line to provide power to electric locomotives and their attached equipment. In the catenary system, as one of the key factors for good contact between the catenary and the locomotive pantograph, a set of integral catenaries need to be installed every 6 - 8 meters on the line to suspend the contact wire on the carrier cable, so as to ensure the suspension height of the contact wire and keep the contact wire elastic to ensure good contact between the catenary and the pantograph. A catenary includes a catenary wire, heart-shaped loops and crimping tubes provided on one or both sides of the catenary wire, and wire terminals provided at one or both ends of the catenary wire. The production process of the catenary mainly includes steps of incoming wire cutting, threading, tensioning, crimping, marking and bundling. Among them, threading includes passing the catenary wire through the crimping tube, heart-shaped loop and wire terminal. Tensioning means using the catenary wire to tension the heart-shaped loop and crimping tube. Crimping includes pressing the crimping tube and wire terminal against the catenary wire.

[0003] Currently, in the construction of traditional railway electrical systems, the catenary wire is generally prepared by manual prefabrication. The preparation of the catenary wire requires pre-assembling the wire terminals, heart-shaped loops and crimping tubes at both ends of the catenary wire, and at the same time, precise control of the length of the catenary wire. The prefabricated catenary wire cannot guarantee the installation accuracy on site, resulting in it being difficult to ensure the construction quality of the entire railway electrical system. Therefore, we propose a catenary prefabrication device. Summary of the Invention

Under the cooperation of the threaded connection between the lead screw 16 and the moving hole, the moving block is driven to move along the first direction, so as to drive the second pressing block 12 and the fourth pressing block 13 to move along the first direction. Furthermore, the second pressing block 12 and the fourth pressing block 13 can approach or move away from the first pressing block 10 and the third pressing block 11;

[0055] It should be noted that a second fixing column 34 is also fixedly provided on the top of the mounting plate 5.

[0064] An operating assembly is provided on the mobile box and includes a control panel 36 . The control panel 36 is electrically connected to the first driving member 17 and the second driving member 24 for controlling the first driving member 17 and the second driving member 24 .

[0065] Thus, by operating the component to control the first driving member 17, the rotation of the first driving shaft drives the rotation of the lead screw, so that the moving block moves in the first direction, realizing the linkage of four actions: pressing the heart-shaped ring 2, pressing the wire nose 4, cutting the wire, and testing the suspension insulator 1.

[0066] An output component 37 is arranged on the moving box. The output component 37 is electrically connected to the operating component and is used for outputting a label containing the information of the suspension insulator 1. The information of the suspension insulator 1 includes the length, tensile strength, etc. of the suspension insulator 1.

[0067] Working principle: First, move the moving box to the required position. During production, take a section of wire from the wire coil, bend the wire around the manual bending post 8 to form the first bending part 6, and at the same time form the first section, which has the first length. Then put on the first crimping tube 3, and install the first heart-shaped ring 2 in the first bending part 6. Put the wire into the first accommodating space, manually pull the wire so that the first crimping tube 3 abuts against the first fixing block, so that the first crimping tube 3 squeezes the first heart-shaped ring 2 to realize the pre-tightening of the first crimping tube 3 and the first heart-shaped ring 2. Subsequently, put the first heart-shaped ring 2 on the second fixing post 34. At this time, the first crimping tube 3 is in the first pressing space. Operate the first driving member 17 through the control panel to drive the lead screw 16 to rotate, so that the moving block moves in the first direction, and the second pressing block 12 approaches the first pressing block 10 to realize the pressing operation on the first crimping tube 3;

[0068] After that, hold the end of the wire far from the first bending part 6 and wind it around the groove of the first disc 20, make a mark on the wire according to the scale 21, then remove the wire, put the marked part in the cutting space, control the first driving member 17 through the control panel 36, and the movement of the moving block drives the movement of the first cutting block 18, so as to cut the wire. After that, bend the wire around the manual bending post 8 again to form the second bending part 7, and at the same time form the second section and the third section. The third section has the first length, and the second section has the second length, and the second length is the required length when making the suspension insulator 1. At this time, the production of the suspension insulator body is completed;

[0069] Then install the second crimping tube 3 and the second heart-shaped ring 2, make the second heart-shaped ring 2 located inside the second bending part 7, and put the second heart-shaped ring 2 on the second fixing post 34. At this time, the suspension insulator body is in the second accommodating space. Put the first heart-shaped ring 2 on the first fixing post 23 in the notch 22 of the first disc 20. Control the second driving member 24 through the control panel 36 to drive the first disc 20 to rotate, so that the second crimping tube 3 abuts against the second fixing block and presses the second heart-shaped ring 2. Then control the first driving member 17 to drive the moving block to move, and the second crimping tube 3 can be pressed; It should be noted that the wire itself has elasticity, so the crimping tube 3 can be installed after forming the second bending part 7;

[0070] After removing the suspension string body, wire nose 4 is respectively installed at one end of the first section away from the first bending part 6 and one end of the third section away from the second bending part 7. Then, the wire nose 4 is placed into the second pressing space, and the first driving part 17 is controlled by the control panel 36 to drive the moving block to move, so as to be able to press the wire nose 4. Thus, the production of the suspension string 1 is completed;

[0071] Finally, two heart-shaped rings 2 are respectively sleeved on the first fixing part and the second fixing part. The suspension string 1 is wound in the groove of the second disc 27. The first driving part 17 is controlled by the control panel 36 to drive the moving block to move, so as to be able to test the suspension string 1. It should be noted that the first driving part 17 can be a torque motor, and the torque data to be tested is input on the control panel 36, so as to be able to perform side wall on the completed suspension string 1. Then, the output component 37 is controlled by the control panel 36 to output a label containing the information of the suspension string 1, and the label is pasted on the suspension string 1.
