A kind of pulling device for hanging string processing

technical field

The invention relates to the technical field of hanging strings, in particular to a wire pulling device for processing hanging strings.

Background technique

The railway catenary hanging string is one of the important components of the chain suspension. The contact wire is hung on the bearing cable through the hanging string. Adjusting the length of the hanging string can ensure the structural height of the contact suspension and the working height of the contact wire from the rail surface. The suspension point of the contact wire is added to improve the current taking quality of the pantograph of the electric locomotive.

In order to ensure the stability of the railway catenary power supply system, the processing quality of the hanging string is relatively high. It is required that the hanging string must be free of loose strands, broken strands, etc. The head is not less than 50mm, and the hanging string must be pre-tensioned to ensure that the hanging string is kept in a stressed state, effectively avoid the deformation caused by the force of the hanging string, and meet the high-speed railway's high-precision requirements for the hanging string. With the continuous improvement of the running speed of China's railways, the requirements for the power supply system of the railway catenary are getting higher and higher. It is of great significance to realize the accurate and efficient completion of the pre-configured processing of the hanging string. In the traditional railway electrical system construction, the hanging string is generally prepared by artificial prefabrication, which has low prefabrication efficiency and large length error of the hanging string.

Detailed ways

The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples are only used to explain the present invention, but not to limit the scope of the present invention.

As shown in Figures 1 to 6, a wire pulling device for hanging string processing includes a machine 1, a support plate 5, a hanging string ring forming module 9 is installed on the supporting plate 5, and the hanging string ring forming module 9 includes a forming table 93 , the forming table 93 is used to bend the hanging string 92 into a "heart-shaped" ring.

The forming table 93 is provided with a hanging string fixing end, and the hanging string fixing end is used to fix the a-end of the hanging string 92 . Two wire feeding wheels 8 are arranged at the front end station of the hanging string ring forming module 9, and the two wire feeding wheels 8 are rotated by the driving motor, and the hanging string wire 92 can be forwarded and reversed. The position b of the hanging string wire 92 enters the hanging string ring forming module 9 through the two wire feeding pulleys 8, and the position b can be understood as an infinite length.

At least one slide rail 2 is slidably connected to the lower side of the support plate 5 , and preferably, the number of slide rails 2 is two. A pulling and moving module is installed on the support plate 5 , and the pulling and moving module is suitable for pulling the support plate 5 to slide along the slide rail 2 . The pulling module includes a motor 6 , the motor 6 is installed on the upper side of the support plate 5 , and a motor installation plate is installed between the motor 6 and the support plate 5 . The output shaft of the motor 6 passes through the support plate 5 , and a gear 11 is installed on the output shaft end of the motor 6 . The lower side of the support plate 5 is provided with a rack 4 , and the gear 11 meshes with the rack 4 . The rack 4 and the slide rail 2 are parallel to each other, and are fixed on the machine table 1 .

The rack 4 is located between the two slide rails 2 . At least four sliding blocks 7 are connected between the support plate 5 and the two sliding rails 2 . A tank chain 3 is connected between the chord ring forming module 9 and the machine table 1, which is used to penetrate wires and air pipes. During the rotation of the motor 6, the gear 11 is driven to rotate, the gear 11 meshes with the rack 4, the gear 11 pushes the rack 4 fixed on the machine table 1, the rack 4 gives a reaction force to the gear 11, and pushes the gear 11 along the rack 11 to move upward, thereby driving the support plate 5 and the entire chord ring forming module 9 to move.

The end a of the hanging string wire 92 is fixed on the hanging string ring forming module 9 , the end b is the pay-off end, the position c is a ring shape, and the lower side of the ring shape is embedded in the clamp tube 91 .
