Description
Technical Field
The utility model belongs to the technical field of the contact net technique and specifically relates to a contact net is with annular registration arm connection structure is related to.
Background
The contact network is an important way for providing power for the electric locomotive by a traction power supply system, plays an important role in the electrified railway, and has a vital significance for ensuring the safety of the contact network in railway transportation. When a train runs, high-frequency violent vibration can be generated, and the integral structure of the contact net is dragged inwards or outwards. In the prior art, the positioning mode of pulling the contact wire to the pillar side through the positioning tube and the positioner is called positive positioning, and the side away from the pillar is reverse positioning.
As shown in figure 1, the positioning pipe is connected to the inclined cantilever, the positioning pipe bears vertical, left and right vibration along with the running of a train due to violent vibration, the part is easy to be unhooked after being deformed due to overlarge stress, the service life is short, and a huge accident is caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an annular registration arm connection structure for contact net can realize the quick dissipation and the transmission of stress, prevents the unhook, improves life.
In order to achieve the above object, the utility model provides an annular registration arm connection structure for contact net, including horizontal body, the front end of body is equipped with the go-between that is located same central line, go-between protrusion in the side of body, the go-between both sides are equipped with the splice bar that extends from the lower extreme to the body side, the upper and lower side of go-between one end is equipped with the arc breach.
Preferably, the notch is a symmetrical arc, and the radian corresponding to the arc length is not less than 90 degrees.
Preferably, the distance between the notches is not less than half of the thickness of the connection ring.
Preferably, the connecting rib is of an inward concave smooth curved surface structure.
Preferably, one end of the connecting rib starts from the inner diameter below the connecting ring and ends at the outer end of the pipe body.
Therefore, the utility model adopts the above-mentioned annular registration arm connection structure for the contact net, can realize the quick dissipation and the transmission of stress, prevent the unhook, improve life.
The technical solution of the present invention is further described in detail by the accompanying drawings and examples.

Detailed Description
The technical solution of the present invention is further explained by the accompanying drawings and examples.
Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by those of ordinary skill in the art to which the invention belongs. The use of "first," "second," and similar terms in the description herein do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item preceding the word comprises the element or item listed after the word and its equivalent, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.
As shown in the figure, the connecting structure of the annular positioning pipe for the contact network comprises a horizontal pipe body 1, a connecting ring 2 located on the same central line is arranged at the front end of the pipe body 1, and the pipe body 1 is connected with an inclined cantilever through the connecting ring 2. The connecting ring 2 protrudes out of the side surface of the tube body 1, so that the bearing strength of the connecting ring 2 is ensured. As the train moves, severe vibrations are transmitted outward through the connecting rings 2 and the protruding connecting ring 2 structure lengthens the force path and dissipates part of the force transmitted forward.
The two sides of the connecting ring 2 are provided with connecting ribs 3 extending from the lower end to the side surface of the tube body 1, and the connecting ribs 3 improve the bearing strength of the connecting ring 2. The connecting ribs 3 are of inward-concave smooth curved surface structures, the structural appearance is attractive, and force is transmitted evenly. One end of the connecting rib 3 starts from the inner diameter below the connecting ring 2 and is terminated at the outer end of the pipe body 1, the connecting rib 3 is reasonable in structure arrangement, balanced transmission of force is further guaranteed, deformation caused by local stress is prevented, and the service life is prolonged.
The upper side and the lower side of one end of the connecting ring 2 are provided with arc-shaped notches 4, and the notches 4 are convenient for the quick clamping of the connecting ring 2. The gap 4 is a symmetrical arc, and the radian corresponding to the arc length is not less than 90 degrees, so that the change of the bearing strength can not be caused when the connecting ring 2 is clamped into the gap rapidly. The distance between the gaps 4 is not less than half of the thickness of the connecting ring 2, so that the bearing strength of the connecting ring 2 is ensured.
Therefore, the utility model adopts the above-mentioned annular registration arm connection structure for the contact net, can realize the quick dissipation and the transmission of stress, prevent the unhook, improve life.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting the same, and although the present invention is described in detail with reference to the preferred embodiments, those skilled in the art should understand that: the technical solution of the present invention can still be modified or replaced by other equivalent means, and the modified technical solution can not be separated from the spirit and scope of the technical solution of the present invention.
