A transition component for a rail transit turnout busbar and a contact wire clamping device

Abstract

This invention discloses a transition component for a rail transit turnout busbar and a contact wire clamping device. The transition component includes a body bent along its length, with a clamping plate at its lower edge capable of clamping the contact wire. The structure of the contact wire clamping device using this transition component includes a pair of transition components, each bent along its length, and an anchoring plate connected to a positioning device. The pair of transition components is fixed to the anchoring plate in an X-shape. Busbars are provided at both ends of each transition component, and clamping plates at the lower edge of each transition component are capable of clamping the contact wire. Using a transition component instead of a busbar avoids the problem of excessively large bending angles in busbars, which are difficult to process. The device has an integrated hyperbolic structure, reducing the amount of positioning suspension parts and the central anchoring device required. The integrated structure ensures that the two contact wires are at the same height.

Description

Technical Field

[0001] This invention relates to the field of rail transit, and more particularly to a contact wire clamping device and transition piece at a turnout. Background Technology

[0002] Existing rigid suspension systems typically use dual mechanically pre-bent busbars for power supply at diamond turnouts. This method has three main drawbacks: 1. The minimum mechanical pre-bending radius of the busbar is relatively large, making it impossible to guarantee the contact wire pull-out value at small-angle diamond turnouts, thus limiting its applicability; 2. The installation of existing dual busbars requires two sets of positioning suspension devices and two sets of center anchoring devices, resulting in a large number of suspension components; 3. After installation, the guide height of the two mechanically pre-bent busbars needs to be adjusted separately, making it difficult to control the construction accuracy. Therefore, developing a new type of diamond turnout contact wire clamping device and locomotive power supply device that has a wider applicability, requires fewer positioning suspension components, and allows for easier control of installation accuracy, while meeting all performance requirements, is of great significance.

[0031] like Figure 1 The busbar transition piece shown is used at a railway turnout. Since the turnout guides the train to change lanes, the contact wire needs to change direction with the vehicle. This transition piece is used to change the direction of the contact wire. The transition piece includes a transition piece body 1, which is bent along its length, that is, the bending direction of the transition piece body 1 is consistent with the direction of the turnout. A clamping plate 2 is provided on the lower edge of the transition piece body 1 to hold the contact wire and fix the contact wire at the turnout bend instead of the busbar. Mounting holes 3 are provided at both ends of the transition piece body 1, and the busbar is fixed to both ends of the transition piece body 1 through the mounting holes 3.

[0032] Figure 2 The clamping plate 2 shown is provided only on one side of the lower edge of the transition body 1, and a clamping edge 1-1 is provided on the side of the lower edge of the transition body 1 opposite to the clamping plate 2. The clamping edge 1-1 and the transition body 1 are an integral unit. The structure of the clamping edge 1-1 is similar to the structure of the working part of the clamping plate 2. The contact line is clamped and fixed by the cooperation of the clamping plate 2 and the clamping edge 1-1.

[0033] like Figure 3 The lower edge of the transition piece body 1 shown is flush and does not have the following features: Figure 2 The clamping edge is in the middle, and a pair of clamping plates 2 are symmetrically arranged on both sides of the lower edge of the transition body 1. The contact line is clamped and fixed by the two clamping plates 2.

[0034] Based on the two embodiments described above, the form of the clamp 2 can also be divided into two embodiments, such as... Figure 4The clamping plate 2 shown is a single piece, and it has the same bending angle as the transition body 1; or it can be made of, for example, Figure 5 The clamping plates 2 shown are arranged in a set along the length of the transition body 1. The length of each clamping plate 2 is determined by its position on the transition body 1. The clamping plate 2 is shorter when it is located at a position with a greater curvature of the transition body 1. This can meet the installation requirements and match the curved part of the transition body 1 (i.e., several sets of short straight lines are spliced ​​together to form a similar arc) through a set of shorter clamping plates 2.

[0035] like Figure 6 The rail transit turnout contact wire clamping device shown is the structure of the aforementioned transition piece combined with a busbar. It includes the transition piece body 1 described above, with busbars 4 fixed at both ends of the transition piece body 1, and a clamping plate 2 fixed to the contact wire at the lower edge of the transition piece body 1. Several different structural forms of the clamping plate 2 and the transition piece body 1 are shown below. Figures 2 to 5 As shown here, the above-mentioned situations can all be used in this structure. Conductive busbars 5 are also provided between the busbars 4 at both ends and the transition body 1.

[0036] Will Figure 6 The clamping device is used in diamond turnouts, such as Figure 7 As shown, the device includes an anchor plate 6 connected to the positioning device A, a pair of transition body 1s, and two transition body 1s fixed in the middle to the anchor plate 6 to form an X shape. Each transition body 1 has a busbar 4 at both ends, and a conductive busbar 5 connects the busbar 4 to the transition body 1 to which it is connected. Each transition body 1 also has a clamping plate 2 at its lower side. The clamping plate 2 and several different structural forms of the transition body 1 are shown below. Figures 2 to 5 As shown, it will not be elaborated further here.
