Abstract
The utility model discloses a suspension loop, and relates to the technical field of power supply facilities of electrified railways. The suspension loop comprises a loop body, wherein the upper portion of the loop body is provided with a transverse through hole, the inside of the lower portion of the loop body is longitudinally provided with a blind hole, the middle of the loop body is provided with a transverse hole at the tail end of the blind hole, and the transverse hole is communicated with the blind hole. Compared with the prior art, by means of the suspension loop, the effective pressure welding length of a stainless steel wire can be visually seen, the situation that the pressure welding length of the stainless steel wire is insufficient is avoided, the use state of the stainless steel wire can be observed by observing the tail end of the stainless steel wire, operational reliability of suspension of overhead line system can be guaranteed, and conditions are provided for little operation cost and maintenance-free condition.
Description
Technical field
The utility model relates to electrified railway power supply facility technical field, especially a kind of hanging ring for contact system push off mode place connection, the horizontal catenary of headspan suspension and the connection of upper and lower part static line.
Background technology
Electric railway mainly is comprised of electric locomotive and traction power set, and traction power set generally is divided into traction substation and contact system two parts.The function of contact system is to contact with the direct of block of bow collector of electric locomotive by it, and electric energy is passed to electric locomotive.China's electric railway main line all adopts the overhead type contact system, and pillar is most widely used fastening in the contact system structure, is used for bearing the load of contact suspension and support equipment.Multiply road contact suspension is suspended on by horizontal clue on the pillar of circuit both sides, and this kind hang is called headspan suspension.
Pillar divides several situations according to the difference of place circuit, adopts the push off mode assembling when its B-C post is positioned at route curve inboard or stagger and is the pillar offside.
During push off mode, steady arm is attached to be hung on long main registration arm, be the horizontal operation state, in order to make main registration arm maintenance level, generally with two lateral conductors, registration arm is hung, be fixed on catenary, lateral conductor is made with stainless steel wire rope, and stainless steel wire rope two ends are respectively together with hanging ring is crimped on.
Headspan suspension is comprised of with the part that horizontal catenary, upper and lower part static line and support on being connected pillar are connected with connection field wire road, station two lateral braces; Laterally catenary is the primary member of headspan suspension, bear whole radial weights of the vertical contact suspension of each strand, two headspan wires that the single headspan wire that is comprised of single catenary according to load weight and double joint catenary form, in horizontal catenary arranged beneath, the upper and lower part static line is arranged, in order to fixing clue in the horizontal direction, and the horizontal load of clue is passed to pillar.
In the mounting structure of headspan suspension, between the static line of upper and lower part, with the double joint lateral conductor, saddle or suspension pulley and steady ring wire clamp are coupled together, can adjust lateral conductor length and make the bottom static line be in level.
In above two kinds of connection modes, all use hanging ring to be used for the pressure connection terminal of stainless steel wire rope, existing hanging ring exists following weak point as shown in Figure 1:
1. do not observe in process of production, the crimping length of rust steel rope.
2. in contact system operation maintenance process, be difficult for checking the use state of stainless steel wire rope.
The utility model content
The utility model provides a kind of hanging ring, and it can solve, and existing hanging ring crimping length is difficult for observing and the difficult problem that checks that it uses state.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: it includes body, the top of this body is provided with cross through hole, the bottom of this body is vertically arranged with blind hole in it, the middle part of described body is provided with a transverse holes in the end of described blind hole, and this transverse holes is communicated with described blind hole.
In technique scheme, scheme is more specifically: described transverse holes is through hole.
Owing to adopting technique scheme, the utility model compared with prior art has following beneficial effect:
1, be positioned at the end in stainless steel wire rope crimping hole due to through hole, can intuitively see effective crimping length of stainless steel wire rope, avoid the problem of stainless steel wire rope crimping length deficiency.
2, contact system operation maintenance process by observing the end of stainless steel wire rope, can be observed the use state of stainless steel wire rope, therefore can guarantee the serviceability of overhead contact line, for operation less, create conditions without maintenance.
Description of drawings
Fig. 1 is the structural representation of existing hanging ring.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the left view of Fig. 2.
The specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawing example:
The present embodiment as shown in Figures 2 and 3, it includes body 1, and the top of this body is provided with cross through hole 2, and this through hole φ is 12.5 ~ 13mm, and the bolt of M12 can be installed, with the connection request of assurance with other part; The bottom of body 1 vertically is drilled with the blind hole 3 that length is about 40mm in it, and the aperture is fit to the crimping requirement of the stainless steel wire rope of various wire diameters; The end that the middle part flat horizontal surface of body 1 is in blind hole 3 is provided with a transverse holes 4, and this transverse holes is communicated with blind hole 3, can observe directly the rope end after the stainless steel wire rope crimping.
Claims (2)
1. a hanging ring, include body, and the top of this body is provided with cross through hole, and the bottom of this body is vertically arranged with blind hole in it, and it is characterized in that: the middle part of described body is provided with a transverse holes in the end of described blind hole, and this transverse holes is communicated with described blind hole.
2. hanging ring according to claim 1, it is characterized in that: described transverse holes is through hole.
