Description

Technical Field

[0001] The utility model relates to the field of dynamic curved track weighing sensors, in particular to an arc-shaped anti-climbing device for curved α steel rails. Background Art

[0002] Dynamic track scales are widely used in national railways and high-speed railways, as well as in railway dedicated lines of large, medium and extra-large industrial and mining enterprises such as steel, metallurgy, coking, petrochemical, energy, thermal power generation, cement and building materials, machinery manufacturing, mining, airports, ports, docks, logistics yards, transfer stations, etc., because they can realize continuous dynamic measurement of each vehicle of freight trains, passenger trains and special railway trains in the process of movement, uniform speed passage, fast measurement speed, accurate measurement, safety and reliability. They can dynamically measure the loaded materials of various rail vehicles and various special rail vehicles, accurately formulate raw materials for large-scale continuous production within working conditions enterprises, and improve the refined measurement of the quality of basic industry products, playing an important role.

[0003] However, in the prior art, most track scales use column pressure sensors. The outer rail is higher than the inner rail at the bend, and the vehicle being weighed is tilted in the direction of the curvature radius. Since the weighing sensor only uses a column pressure weighing sensor structure, the specific gravity of the items loaded on the vehicle is different, and the center of gravity height is different; in addition, there is a lack of horizontal force measurement sensors for the centrifugal force and centripetal force of vehicles on curves. The vertical force sensor alone cannot detect the errors caused by the actual acceleration, centrifugal force and centripetal force when the vehicle turns; furthermore, the column pressure sensor installed at the curve position, when installed in a sloped position on the curve, is affected by the lateral force, which greatly reduces the technical indicators of the sensor itself, such as linearity, hysteresis, and repeatability. In addition, the previous curved track scales are of the broken rail type, which poses a greater safety hazard to vehicles traveling in the curved area. Therefore, a curved α rail arc anti-climbing device is proposed. Utility Model Content

[0004] In order to solve the defects and shortcomings in the prior art, the utility model provides a curved α rail arc anti-climbing device which can overcome the thermal expansion and contraction of the rails in or outside the curved weighing area due to seasonal changes, or the rail climbing and stringing caused by the loosening of the outer rail fasteners, and avoid and reduce the unstable influence on the measurement caused by the sudden change of the pulling force or the extrusion force generated by the outer rail on the curved weighing rail.

The male and female curved α rail arc-shaped anti-climbing device brackets are two curved α rail arc-shaped anti-climbing device brackets installed on both sides of the rail. The two curved α rail arc-shaped anti-climbing device brackets and the rail are connected through the rail anti-climbing rod, and the two ends of the rail anti-climbing rod are respectively locked by cotter pins.

[0006] Preferably, a U-shaped notch matching the rail anti-climbing rod is provided on the top of each curved α rail arc anti-climbing device bracket, and an anti-climbing rod insulating sleeve is provided between the rail anti-climbing rod and the U-shaped notch.

[0007] Preferably, a limiting ring is provided at one end of the anti-climbing rod insulating sleeve, and the limiting ring is located on the outside of the corresponding curve α rail arc-shaped anti-climbing device bracket, and one end of the anti-climbing rod insulating sleeve passes through the anti-climbing hole of the corresponding curve α rail arc-shaped anti-climbing device bracket and is exposed outside the anti-climbing hole.

[0008] Preferably, the thickness of the limit ring is smaller than the distance between the open pin and the outer side of the corresponding curve α rail arc anti-climbing device bracket, and the length of the anti-climbing rod insulating sleeve is greater than the distance between the open pin and the outer side of the corresponding curve α rail arc anti-climbing device bracket.

[0009] Preferably, an arc groove matching the radius of curvature of the curved bend area and the size of the rail model used in the line is formed between the two curved α rail arc anti-climbing device brackets.

[0010] Preferably, the height of one curve α rail arc anti-climbing device bracket is higher than the height of another curve α rail arc anti-climbing device bracket, and the rail anti-climbing rod is inclined, and the inclination angle matches the inclination angle of the rail.

[0011] Preferably, the two curved α rail arc anti-climbing device brackets are designed to be arc-shaped consistent with the curvature radius of the curve, ensuring the arc transition of the rail in the curve, avoiding the breakage of the commonly used straight-strip insulating pads in railways after being stressed, and playing a safety role.

[0012] The utility model has the following beneficial effects: the utility model can overcome the rail creeping and stringing caused by thermal expansion and contraction caused by seasonal changes in or outside the curve weighing area or the outer rail fasteners looseness, and avoid and reduce the unstable influence on the measurement caused by the sudden change of the pulling force or squeezing force generated by the outer rail on the curve weighing rail.
