Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of weathering steel steel pipe supports for catenaries, and relates to a weathering steel steel pipe support for a catenary. Background Art
[0002] At present, China's high-speed railways are developing rapidly. According to the "Code for Design of Railway Electric Traction Power Supply", in today's railway construction, the ring-shaped steel pipe supports for catenaries are still the main types of supports selected in the lines with a speed of 250 km / h. The ring-shaped steel pipe supports are relatively simple to process and manufacture, have a stable structure, and are convenient to install, and are widely used in the fields of high-speed railways, passenger dedicated lines, urban rail transit, etc.
[0003] During the application process of the ring-shaped steel pipe supports, some problems in use have gradually emerged: (1) At present, the standard stipulates that the basic anti-corrosion methods adopted for the ring-shaped steel pipe supports are hot-dip galvanizing or hot-dip galvanizing + anti-corrosion coating. These anti-corrosion methods can ensure the normal service life of the products in general areas, but in special areas such as industrial pollution areas and coastal areas, the products under this anti-corrosion method rust quickly, thus reducing the service life of the products, increasing the maintenance cost, and having potential safety hazards. (2) The column body of the ring-shaped steel pipe support is tubular, the outer wall is smooth, and there is no reliable stress point, making it difficult to hoist the product itself, and safety problems are likely to occur during installation. In addition, after the support is installed on the railway line, a hoop interface needs to be installed on the column body to install the catenary components. After the catenary components are installed, the hoop is subjected to large forces and is likely to slide along both ends of the support, causing potential hazards such as inaccurate catenary positioning and operation safety. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the above problems existing in the prior art, and provide a weathering steel steel pipe support for a catenary, which has strong anti-corrosion performance, extends the service life, reduces the maintenance cost and potential safety hazards; the support and fixation of the catenary components are good, the catenary positioning is accurate, and potential hazards such as operation safety are no longer generated due to this.
[0005] To achieve the above purpose, the technical solution of the utility model is: a weathering steel steel pipe support for a catenary, including a support, one or more support connectors, a sealing top plate and a support base; the sealing top plate is fixed at the upper end of the support, and the support base is fixed at the lower end of the support; each support connector is fixed on one side of the upper end of the support; the support connector includes a flange bottom plate, a support plate and two stiffening plates. The flange bottom plate is fixed on the side of the support by the support plate and the two stiffening plates. The two stiffening plates are respectively located on both sides of the support plate. Two rows of multiple rows of installation holes for catenary components are opened on the flange bottom plate; the support, the support connector, the sealing top plate and the support base are all made of weathering steel.
[0006] Further preferably, a main support rib I and an auxiliary support rib II made of weathering steel are also fixed between the support base and the pillar, making the installation of the pillar more stable.
[0007] Further preferably, the flange bottom plate of the support connecting piece is a rectangle with rounded corners, so as to have more rows of installation holes for catenary components, making the installation position of the catenary components more accurate.
[0008] The advantages of the present utility model compared with the prior art are as follows: The present utility model is made of weathering steel, with strong anti-corrosion performance, not easily corroded in special areas such as industrial pollution areas and coastal areas, having a long service life, reducing maintenance costs and potential safety hazards. The support and fixation of the catenary components are good, the catenary components no longer slide along the pillar, the positioning is accurate, and no potential safety hazards such as operation safety are generated. Moreover, the support connecting piece of the present utility model can be used as a lifting interface, increasing the stability of lifting. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following further describes the present utility model in conjunction with the drawings and specific embodiments.
[0016] As Figures 1 to 6As shown in the figure, this embodiment includes columns 2, two (or one, three, four, etc.) support connectors, a sealing top plate 6, and a support base 4. The sealing top plate 6 is welded and fixed to the upper end of the column 2, and the support base 4 is welded and fixed to the lower end of the column 2. Each support connector is fixed to one side of the upper end of the column 2. The support connector includes a flange bottom plate 1, a support plate 12, and two stiffening plates 11; the flange bottom plate 1 is welded and fixed to the side of the column 2 by the support plate 12 and the two stiffening plates 11 which are welded and fixed. The two stiffening plates 11 are respectively located on both sides of the support plate 12. Two rows and three columns (or two rows, four rows, etc.) of mounting holes 13 for catenary components are provided on the flange bottom plate 1. The column 2, the support connector, the sealing top plate 6, and the support base 4 are all made of weathering steel. Preferably, a main support rib I 3 and an auxiliary support rib II 4 made of weathering steel are also welded and fixed between the support base 4 and the column 2; to make the installation of the column 2 more stable. Preferably, the flange bottom plate 1 of the support connector is a rectangle with rounded corners; so as to have more rows of mounting holes 13 for catenary components at a certain position, making the installation position of the catenary components more accurate.
