Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.
Referring to fig. 1, the invention discloses a suspended monorail contact rail system, which comprises a rail beam 4, two contact rails 1 arranged on the inner side of the rail beam 4, and a contact plate 2. The two contact rails 1 are respectively connected with the positive pole and the negative pole of an external power grid. The contact plate 2 is located on the side of the contact rail 1 facing away from the track beam 4, and the contact plate 2 is used for contacting with a collector shoe on a train. The two contact rails 1 are parallel and distributed up and down. The distance between the centers of the two contact rails 1 is 102.5 mm. The contact rail 1 is also subjected to epoxy resin desulfurization insulation treatment.
Two contact rails 1 are fixed on a track beam 4 through a plurality of groups of insulators 3, and each group of insulators 3 comprises two and are respectively connected with the two contact rails 1. Two insulators 3 of a group are distributed up and down. The insulator 3 is made of a silica gel body.
One end of the insulator 3 is provided with a screw 31, the screw 31 penetrates through the track beam 4 and is fixed through a nut 32, the screw 31 extends out of the nut 32, one pin shaft 51 penetrates through two screw rods 31 in a group, the pin shaft 51 is in a vertical state, and a cotter pin 52 is further arranged at the bottom of the pin shaft 51 to prevent the pin shaft 51 from moving.
The other end of the insulator 3 is provided with an annular flange 33, a C-shaped groove 11 is formed in one side, facing the track beam 4, of the contact rail 1, and the flange 33 is located in the C-shaped groove 11 and is in tight fit with the C-shaped groove 11. The flange 33 will provide support for the contact rail 1.
A rubber pad 6 for buffering is also arranged between the insulator 3 and the track beam 4. When the nut 32 is engaged with the screw 31 to fix the insulator 3, the rubber pad 6 is clamped between the insulator 3 and the track beam 4.
Two grooves 12 are further formed in the bottom of the C-shaped groove 11, and the grooves 12 are used for increasing the surface area of the contact rail 1, so that the current carrying capacity of the contact rail is increased.
The contact rail is bent to be C type, and the contact rail has the bulge 13 that the cross-section is T type towards the one end protrusion of contact plate 2, and as shown in the figure, contact plate 2 cladding is on bulge 13 and pass through the bolt fastening.
The contact plate 2 is in contact with the collector shoe at a surface distance of 110mm from the track beam 4.
An electric connection inner clamping plate and an electric connection outer clamping plate are respectively arranged inside and outside the C-shaped groove 11, the shape of the electric connection inner clamping plate is matched with that of the C-shaped groove 11, the electric connection inner clamping plate is in contact with the contact rail 1, and the electric connection outer clamping plate is connected with the electric connection inner clamping plate through bolts; the other end of the electric connection outer clamping plate is connected with a connecting terminal, and the two connecting terminals which are electrically connected with the two contact rails 1 are respectively connected with the anode and the cathode of an external power grid.
In practical implementation, because the collector shoe and the contact plate 2 are in rigid contact, the train inevitably vibrates in operation, and the track of the train is relatively deviated due to installation errors of the track and the contact rail 1, so that the collector shoe generates extra force to the contact plate 2 in operation of the train, which reduces the service life of the contact rail 1, the contact plate 2 and the insulator 3. The rubber pad 6 can play a role of buffering, and can effectively reduce noise generated by the collector shoe and the contact plate 2 in the actual operation process.
Meanwhile, due to the impact and vibration effects, although the gasket and the elastic pad are installed at the nut 32 to be loosened, the insulator 3 may still rotate during actual operation, so that the rotation of the insulator 3 can be limited after the set pin shaft 51 penetrates through the two screw rods 31, and the structural stability is improved. The pin 51 is further restrained by a cotter pin 52.
At the same time, the flange 33 and the C-shaped groove 11 cooperate in such a way that the supported area of the busbar 1 is larger, i.e. it can be understood that the range of space that can be occupied by the busbar 1 itself is smaller for the same supported area. Simultaneously, optimized the cooperation mode and the cooperation structure of insulator 3 and conductor rail 1, when carrying out the installation of conductor rail 1, only need in advance flange 33 from the one end of conductor rail 1 slide in the assigned position in C type groove 11 can, with the conductor rail 1 alignment mounted position this moment, through nut 32 with each insulator 3 fixed can.
Further, the use of the insulator 3 can also reduce the design cost at the initial stage of design, simplify the support structure, and because the insulator 3 belongs to mass production products, the material cost can also be reduced.
