Abstract
The utility model belongs to the field of electrified railway catenary networks and relates to an elastic wire clamp of a bus bar. The wire clamp (6) is formed by opposite connection of two half units with the same shape, and the bottom of each half unit is bended inwards. The elastic wire clamp is characterized in that a transverse blind hole (62) is formed at the connecting part (64) between the top clamping plate part (61) and the bottom of each half unit of the wire clamp, and a pin column (3) is accommodated in the transverse blind holes (62) after the two half units are connected oppositely. The elastic wire clamp of the bus bar is convenient to be processed, installed and repaired. Only by inserting the clamping plate parts, from bottom to top, into the through groove of the cylinder after the two half units are connected oppositely and then rotating 90 degrees, the clamping plate parts enters the cylinder through groove that has matching size with the clamping plate parts of the wire clamp, so that the two half units have the self-tightening force under the action of the blind holes, the connecting part between the clamping plate parts and the bottom and the through groove, without needing bolt fasteners. The two transverse blind holes which are arranged in up-and-down manner to accommodate the pin column (8) can ensure accurate opposite connection of the two half units.
Description
Technical field:
The utility model relates to a kind of bus duct wire clamp, belongs to the electrification railway contact net field.
Background technology:
Overheat rigid contact network with the elasticity wire clamp be used for fixing, rigidity of support contact system bus duct, along with the fast development of Construction of Urban Rail Traffic, the rigidity overhead contact line is because its advantage such as non-maintaining replaces the trend of the times of flexible overhead contact line.Rigid contact net is to adopt the rigid support insulator to be installed on the channel beam of tunnel top.Existing bus duct elasticity wire clamp is formed by two shape identical halves butt joints, and the bottom of each half one bends inwards, and is when installing bus duct, with a bolt that the butt joint of two and half is fixing again.This structure one is the installation, maintenance trouble, and workmen's labour intensity is big, the 2nd, and with a bolted connection, two and half ones are easy to generate and relatively rotate, and influence the correct installation site of bus duct.
The utility model content:
The purpose of this utility model provides a kind of simple in structure, bus duct elasticity wire clamp of making things convenient for installation, maintenance.
The utility model purpose can be finished by the following technical programs:
A kind of bus duct elasticity wire clamp, wire clamp is formed by two shape identical halves butt joints, the bottom of each half one bends inwards, and it is characterized in that the top card board of each wire clamp half one and the connecting portion between the bottom have horizontal blind hole, and the horizontal blind hole of two and half butt joint is equipped with pin.
The quantity of the horizontal blind hole of described each wire clamp half one is two, is arranged above and below.
The interior angle of the bending place of described wire clamp is provided with plastic cushion (of tie bar).
Described wire clamp is made by corrosion-resistant steel or copper material.
The utility model makes things convenient for processing, installation and the maintenance of part especially, as long as being stretched into groove from bottom to top, the clamp portion of two and half butt joints amalgamation wire clamp enters cylindrical shell, rotate 90 ° then, clamp portion promptly enters in size and the blind groove that the clamp portion of wire clamp cooperates, at this moment because the connecting portion between blind groove and clamp portion and the bottom and the effect of groove, two and half ones are produced self-tightening power, need not bolt up again.Two horizontal blind holes that are arranged above and below for ccontaining pins can make two and half ones accurately dock, and prevent the easy rotation phenomenon of single screw rod state, and the reliability height of long-time running helps reducing the construction and the over-the-road expense of contact system.

The specific embodiment
With reference to Fig. 1-Fig. 4, two shape identical halves butt joints that described wire clamp 6 is made by corrosion-resistant steel are put together, the bottom of each half one bends inwards, be used for the company's of extension bus duct, the horizontal blind hole 62 that connecting portion 64 places between online ogival sections clamp portion 61 and the bottom have 62, two half butt joints of two horizontal blind holes that are arranged above and below is equipped with pin 8.Contact the wearing and tearing that produce with the wire clamp rigidity in order to reduce bus duct, the interior angle in the bending place 63 of wire clamp 6 is provided with plastic cushion (of tie bar) 7.
With reference to Fig. 5, Fig. 6, self-clinching chucking busbar elastic wire clip with the overheat rigid contact network that is used for electrified railway of the utility model matching design, comprise being used for and girder steel bonded assembly peg 1 that its top connector 11 is shaped on through hole, be used for being connected with the steelframe suspension by insulator.Cylindrical shell 5 is made by corrosion-resistant steel, and the cylindrical rubber elastic layer 3 that has axis hole is equipped with in inside, and the end face of this rubber elastic layer and bottom surface are provided with top board 2 and base plate 4 respectively, top board 2 with the cylindrical shell welded top, constitute the top cover of cylindrical shell 5.Peg 1 bottom has the pin-and-hole that runs through for backing pin 12, and this pin-and-hole is positioned at the below, bottom surface of base plate 4, limits the position of base plate 4.Peg 1 runs through the axis hole of top board 2, rubber elastic layer 3 and base plate 4 is held by backing pin 12 in base plate 4 backs, thereby the relative peg of whole cylindrical shell is moved up and down.The bottom surface of cylindrical shell 5 has the groove 52 that size cooperates with the clamp portion 61 of wire clamp 6, having the blind groove 53 that size cooperates with the clamp portion 61 of wire clamp with the position, bottom surface of the cylindrical shell of this groove perpendicular, the clamp portion 61 at wire clamp 6 tops stretches into and is stuck in the blind groove 53 of inner bottom surface of cylindrical shell 5.Because top cover 2 is captiveed joint with the top of cylindrical shell 5, like this when running condition, under the deadweight loading of bus duct and contact wire, cylindrical shell 5 moves down, and base plate 4 is fixing with peg 4, and the rubber elastic layer 3 of bus duct elasticity wire clamp is in vertical compressive state, when this bus duct elasticity wire clamp place of pantograph operation process, the bus duct steady ear is subjected to the moment upward pressure of pantograph in the train operation, and rubber elastic layer upwards restores to the original state, and absorbs impact energy.
This structure, make things convenient for processing, installation and the maintenance of wire clamp especially, as long as being stretched into groove 52 from bottom to top, the clamp portion 61 of two and half butt joints amalgamation wire clamp enters cylindrical shell, rotate 90 ° then, clamp portion 61 promptly enters in size and the blind groove 53 that the clamp portion of wire clamp cooperates, at this moment because the connecting portion 64 between blind groove and clamp portion and the bottom and the effect of groove 52 produce self-tightening power to two and half ones, need not bolt up again.Two horizontal blind holes 62 that are arranged above and below for ccontaining pins 8 can make two and half ones accurately dock, and prevent the easy rotation phenomenon of single screw rod state, and the reliability height of long-time running helps reducing the construction and the over-the-road expense of contact system.
