Description

Straddle monorail simple flexible turnout

technical field

The utility model belongs to the field of straddle-type monorail traffic systems, in particular to a simple and flexible turnout of a straddle-type monorail.

Background technique

Turnout is an important mechanical and electrical equipment for straddle-type monorail traffic, and it is divided into two basic forms: articulated type and flexible type. The articulated single turnout has a simple structure and relatively low cost. However, since the articulated turnout is composed of four turnout beams 1 forming broken lines, guide plates 2 and stabilizing plates are installed on both sides of each turnout beam 1, as shown in Figure 9 When the train passes the turnout, the turnout beam will have a great impact on the train. This impact is very harmful. It may cause permanent damage to the vehicle structure and reduce the ride comfort of the train. The train can only pass through the articulated turnout at a speed limit, so the articulated turnout generally cannot be installed on the main line. The linear shape of the flexible turnout is a circular arc transition, so it will not cause damage to the train, and the passing speed is much higher than that of the articulated turnout. The turnouts installed on the main line are all flexible turnouts. However, the structure of the flexible turnout is very complicated, such as a straddle-type flexible single-track turnout side plate deformation device disclosed in Chinese patent 200520033310. It is very difficult to install, and the cost is several times higher than that of the articulated turnout.

Utility model content

The technical problem to be solved by the utility model is to provide a simple flexible turnout with a straddle-type monorail function and low cost.

In order to achieve the above object, the technical scheme of the utility model is as follows: a simple and flexible turnout of a straddle-type monorail, including a connected turnout beam, and guide plates and stabilizing plates installed on both sides of each turnout beam. The two sides of the joint section of the turnout beam are hinged with an outer flexible plate and an inner flexible plate, and the front and rear ends of the outer flexible plate and the inner flexible plate are respectively hinged on the side of the turnout beam through pin shafts, and the The front or rear ends of the outer flexible plate and the inner flexible plate are hinged holes for the pin to pass through as strip holes; the middle part of the outer flexible plate is hinged on the side of the turnout beam through a roller, so The middle part of the inner flexible plate is hinged on the side surface of the turnout beam through the connecting plate.

The inner surfaces of the front and rear ends of the outer flexible plate and the inner flexible plate are respectively provided with lugs, and the lugs are hinged to the hinge seats on the side of the corresponding turnout beam through the pin shaft.

The middle part of the outer flexible plate is welded with a circular bearing seat, and a support seat is arranged on the side of the turnout beam corresponding to the bearing seat; the roller passes through the support seat and the bearing seat to connect the two.

The middle part of the inner flexible plate is provided with a hinged lug, which is hinged to one end of the connecting plate, and the other end of the connecting plate is hinged to the hinged lug on the side of the turnout beam.

Beneficial effects: the utility model does not change the basic design of the existing single track turnout, and provides a monorail turnout with a price equivalent to that of the joint type turnout and partially flexible turnout functions for monorail traffic. This kind of turnout not only has the characteristics of simple structure and low cost of joint type turnout, but also has the characteristics of smooth line and shape of flexible type turnout, and has the characteristics of small damage and impact force to trains. It can greatly improve the passing performance of articulated turnouts, and if necessary, it can replace some flexible turnouts and be installed on the main line.

Detailed ways

Below in conjunction with accompanying drawing and embodiment further illustrate the utility model.

The driving system, locking system and control system in the utility model are the same as the existing articulated switch. As shown in Figures 1 to 6, a pair of single-opening turnouts generally consists of 4 section beams, and two adjacent sections of turnout beams 7 and 8 are connected by connecting devices, and are rigidly connected on both sides of each section of turnout beams 7 and 8 There are a guide plate 1 and a stabilizing plate 9, and an outer flexible plate 2 and an inner flexible plate 3 are hinged on both sides of the joint of the turnout beam 7 and 8 described in the two sections, and the outer flexible plate 2 and the inner flexible plate 3 are front 1. Each lug 10 is installed on the inner surface of the rear end, and the lug 10 is hinged on the hinge seat 11 on the side of the corresponding turnout beam 7 or 8 through the pin shaft 4, as shown in Figure 3 and Figure 4, the outer flexible plate 2 The hinged hole through which the front end pin shaft 4 of the inner flexible board 3 passes is a strip hole, and the hinged hole through which the rear end pin shaft 4 of the outer flexible board 2 and the inner flexible board 3 passes is a round hole, so that when When the turnout girder switches, the rear end of the flexible plate can only rotate on the flexible axis, and the strip holes are used to compensate the position of the flexible plate and restrain the lateral movement of the flexible plate.

As shown in Fig. 6, Fig. 7 and Fig. 8, a circular bearing seat 12 is welded in the middle of the outer flexible plate 2, and a supporting seat 13 is arranged on the side of the turnout beam 7 or 8 corresponding to the bearing seat 12, and the roller 5 Pass through the support seat 13 and the bearing seat 12 to connect the two. When the turnout beam switches, the roller 5 exerts force on the outer flexible plate 2, and the outer flexible plate 2 protrudes outward; the inner flexible plate 3 The middle part is provided with hinge lug 14, and this hinge lug 14 is hinged with one end of described connection plate 6, and the other end of described connection plate 6 is hinged on the hinge lug 15 of described turnout beam 7 or 8 side, when turnout When the beam switches and moves, the connecting plate 6 pulls the inner flexible plate 3 to be recessed inward. Since the connecting plate 6 and the roller 5 are not rigidly connected to the outer flexible plate 2 and the inner flexible plate 3, the axial displacement of the flexible plate during deformation is compensated. In this way, under the action of the turnout drive system, the main body of the turnout beam moves according to the prescribed track, and drives the flexible plate to bend and deform, so that the entire turnout beam guide plate and stable plate form a relatively smooth linear shape.
