Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0050] It should be noted in advance that the contact wire cantilever arm 100 includes a horizontal cantilever arm 101 and a supporting cantilever arm 102. The horizontal cantilever arm 101 is connected to the first connecting base on the H-beam steel column through the mounting hole at the end of the first insulator 104. One end of the supporting cantilever arm 102 is slidably mounted on the horizontal cantilever arm 101 through the sleeve 103. The other end of the supporting cantilever arm 102 is connected to the second connecting base on the H-beam steel column through the mounting hole at the end of the second insulator 105. The horizontal cantilever arm 101 is provided with the first insulator 104 at the end near the first connecting base, and the supporting cantilever arm 102 is provided with the second insulator 105 at the end away from the sleeve 103.

[0051] Reference Figures 1-10 As shown, a first aspect of the present invention provides a method for installing a railway overhead contact line cantilever arm, comprising a base 1, a first clamping mechanism 2, a first moving mechanism 3, a second clamping mechanism 4, and a second moving mechanism 5, wherein:

[0052] The base 1 can be connected to the robotic arm. The robotic arm drives the base 1 to rotate and move, which can align the plane where the horizontal cantilever arm 101 and the supporting cantilever arm 102 are located with the mounting surface of the first connecting base on the H-shaped steel column, and drive the installation method of the railway contact network cantilever arm to move as a whole, so that the mounting hole at the end of the first insulator 104 on the horizontal cantilever arm 101 is connected to the first connecting base on the H-shaped steel column.

[0053] The first clamping mechanism 2 is used to clamp and support the horizontal wrist arm 101; two first clamping mechanisms 2 can be provided, and the two first clamping mechanisms 2 can provide better support for the horizontal wrist arm 101 after clamping it, resulting in better stability;

[0054] The first moving mechanism 3 is mounted on the base 1 and connected to the first clamping mechanism 2, and is used to drive the first clamping mechanism 2 to move along the length direction of the horizontal wrist arm 101;

[0055] The second clamping mechanism 4 is used to clamp the supporting arm 102;

[0056] The second moving mechanism 5 comprises a rotating piece 51, a connecting seat 52, a longitudinal moving unit 53 and a transverse moving unit 54, the rotating piece 51 is connected with the second clamping mechanism 4 and the connecting seat 52 respectively, the connecting seat 52 is connected with the transverse moving unit 54, the longitudinal moving unit 53 is installed on the base 1 and connected with the transverse moving unit 54, the longitudinal moving unit 53 and the transverse moving unit 54 are used for driving the connecting seat 52 to move longitudinally and transversely respectively, so as to adjust the position of the second clamping mechanism, meet the support arm 102 of different sizes and different angles, and drive the support arm 102 to rotate around the sleeve 103 after the second clamping mechanism clamps the support arm, so as to adjust the distance between the end of the support arm 102 away from the sleeve 103 and the horizontal arm 101 to the distance of assembly (i.e. the hole distance between the mounting hole at the end of the first insulator 104 and the mounting hole at the end of the second insulator 105). During the movement of the connecting seat 52, the rotating piece 51 is used to adjust the angle of the second clamping mechanism, so that the second clamping mechanism 4 is parallel to the length direction of the support arm 102, so that the movement can be stably carried out, and the stability and reliability are improved. The rotating piece 51 can be a bearing.

[0057] It should be noted that, since it is desired that the hole distance between the mounting hole at the end of the first insulator 104 and the mounting hole at the end of the second insulator 105 is the same, the angle between the horizontal arm 101 and the support arm 102 of different sizes will be different, the distance between the end of the support arm 102 away from the sleeve 103 and the horizontal arm 101 is adjusted before clamping, so the second moving mechanism 5 is needed to adjust the position of the second clamping mechanism 4.

[0058] The installation method of the railway catenary arm provided by the embodiment of the application can avoid the sleeve 103 and the first insulator 104 on the horizontal arm 101 after the first clamping mechanism 2 clamps the horizontal arm 101 by adjusting the position of the first clamping mechanism 2, increase the universality of the arm tooling, improve the reliability of the device, the second clamping mechanism 4 clamps the support arm 102, the longitudinal moving unit 53 and the transverse moving unit 54 drive the connecting seat 52 to move longitudinally and transversely respectively, so as to drive the support arm 102 to rotate around the sleeve 103, adjust the distance between the end of the support arm 102 away from the sleeve 103 and the horizontal arm 101 to the distance of assembly, so that the end of the support arm 102 away from the sleeve 103 is connected with the second connecting seat 52 on the H-shaped steel column, and the attitude of each component is directly adjusted during the assembly at the construction site, so that the assembly speed is fast and the efficiency is high.

The push block 231, the driving arms 232 and the first clamping jaws 24 constitute a planar linkage mechanism, the push block 231 is driven to move by the first driving member 22, and the push block 231 moves along the direction of the guide grooves 211 due to the guidance of the guide grooves 211, the push block 231 drives the driving arms 232 to rotate, the driving arms 232 drive the first clamping jaws 24 to rotate around the points hinged to the first mounting base 21, so that the two first clamping jaws 24 are close to or away from each other.

The first screw rod 31 is driven to rotate by the second driving member 32, and the second mounting base 33 cannot rotate due to being limited by the two first guide rods 34, so that the second mounting base 33 can only slide along the first guide rods 34 under the driving of the first screw rod 31, the second mounting base 33 drives the first mounting base 21 to move together in the sliding process, so as to drive the first clamping mechanism 2 to move. After the clamping position of the horizontal arm 101 is selected, the left and right first clamping mechanisms 2 clamp the horizontal arm 101 at the same time.
