Abstract

The utility model provides a railway switch rotation type connecting device. The rotary connecting track comprises a chassis, a rotary connecting track hinged on the chassis through a positioning shaft, a front left and right connecting track with front left and right track interfaces and a rear left and right connecting track with rear left and right track interfaces, which are respectively positioned in front of and at the rear end of the rotary connecting track and are arranged on the chassis, arc surfaces concentric with the positioning shaft are respectively arranged at the front and rear interface ends of the rotary connecting track, arc surfaces matched with the arc surfaces at the front and rear interface ends of the rotary connecting track are respectively arranged at the front left and right track interface ends on the front left and right connecting track and the rear left and right track interface ends on the rear left and right connecting track, and a control mechanism for enabling the rotary connecting track to swing is arranged on the chassis. The utility model discloses overcome the train completely and produced violently jolt, vibrations etc. when passing through the switch and be unfavorable for the factor that the train travel, improved the life of train and rail.

Description

The rotary connecting device of railway switch

Technical field:

This usefulness is novel, and what relate to is a kind of track switch connecting device that is used on the railway, particularly be the rotary connecting device of a kind of railway switch.

Background technology:

Existing railway triangle track switch is all rolled straddle type, promptly Yun Hang train wheels when the track switch of intersecting by two strands of rails, must roll across leave another rail for wheel along groove.This groove that leaves by the vehicle wheel edge, the width at the edge from polygonal tip to other end track has 180mm, ditch depth that 70mm is arranged approximately approximately, and again because the long-term use of rail track switch, bump damages, and turns round that to stick up distortion extremely serious, and the groove width that has has more than the 300mm approximately.Train will produce by such track switch the time and violent jolt, shake, wave, interlacing etc. of rigidity bump, sloping bank resistance, front and back two railway carriages is unfavorable for the factor of train driving, the mutual damage of train and rail also is very serious, and is vicious circle.

The utility model content:

The purpose of this utility model be for provide a kind of can overcome that train produced by track switch the time be unfavorable for all multifactor of train driving, eliminate wheel along groove, improve the service life of train and rail, reduce service expenditure, reduce the rotary connecting device of railway switch of kinetic equation loss.

The purpose of this utility model is achieved in that

The utility model comprises the chassis, be hinged on rotary connection track on the chassis by fix shaft, before laying respectively at the rotary connection track, rear end and be contained in the preceding left side that contains on the chassis, integrate with about right Rail joint preceding, contain a left side, back, integrate with about right Rail joint back, before the rotary connection track, rear interface end has the arc surface concentric with fix shaft respectively, preceding left side on integrating with about preceding, right Rail joint end, a back left side that integrates with about the back, right Rail joint end has respectively and rotarys connection before the track, the arc surface that the rear interface end arc surface cooperates, the control mechanism that makes the swing of rotary connection track is arranged on the chassis, utilize the principle of centering rotation, each Rail joint place is designed to arc surface, so the track joint does not have groove.

Above-mentioned control mechanism comprises the screw rodb base (20,21) that is contained on the chassis, nut, screw mandrel one end is through successively on the screw rodb base and with nut thread and is connected, nut top penetrates in the rotary seat rotating hole on the rotary connection track, control mechanism also can adopt hydraulic pressure, connecting rod electromagnetism, etc. form, can adopt modes such as workman, remote control, computer controlled to operate control mechanism.

Track width in the above-mentioned rotary connection track with preceding about integrate with and the back about track width on integrating with identical, make to be linked to be a straight track between each track.

Referring to Fig. 1, Fig. 2, when using the utility model, forward revolves screw mandrel, the screw mandrel driven rotary connects track and rotates along clockwise direction around fix shaft, reach front end that the left side track that integrates with about rotary connection rail rear end and back connected, rotaryed connection track with preceding about the right track connection of integrating with, at this moment, the left side track, rotary connection track that integrates with about the back, the right track, the head and the tail that integrate with about preceding connect into a straight track; Opposite spin control mechanism screw mandrel, rotary connection track just around fix shaft along C.C.W. direction rotation, the left side track that reaches the right track of integrating with about the back, rotary connection track, integrates with about preceding joins end to end into a straight track.Train will pass through that track, just connects that track.Train just can by rotation track switch connecting device, advance, all can fall back along the track of connecting, and is very steady.

Train is by the rotary connecting device of the utility model railway switch the time, and wheel is to roll to integrate with between ecotone in the front and back that do not have groove, and as travelling on same track, it is also very steady to slow down.Overcome the factor that the severe jolt that train is produced, vibrations etc. are unfavorable for train driving fully by track switch the time, and the mutual damage between train and the rail, suppressed effectively to stick up distortion because of turning round of being produced of rail long-term use, improved the service life of train and rail, reduced the service expenditure and the kinetic equation loss of train and rail, created good condition for train raises speed by a larger margin.

Description of drawings:

Fig. 1 is the utility model structural representation.

Fig. 2 is the birds-eye view of Fig. 1.

The specific embodiment mode:

Referring to Fig. 1, Fig. 2, be hinged with rotary connection track 3 by fix shaft 2 on the chassis 1, be positioned at and integrate with 4 about rotary connection track 3 front and back ends preceding, integrate with 5 about the back.Before about integrate with integrate with about left track 6 on 4, right track 7, the back shape of left track 8 on 5, right track 9 all identical with the shape of track 10 in the rotary connection track 3.The forward and backward

interface end

11,12 of the track 10 of rotary connection track 3 has the arc surface concentric with fix shaft 2 respectively.Before about integrate with 4 preceding left Rail joint end 13, preceding right

Rail joint end

14,5 the back left Rail joint end 15 of integrating with about the back, the right Rail joint end 16 in back have the arc surface that cooperates with the forward and backward interface end arc surface of the track 10 of rotary connection track 3.On the rotary seat 17 of rotary connection track rotating hole 18 is arranged.

Screw rodb base
