Rail rolling wheel device and seamlessly crossed steel rail matched with same for use

Abstract

The invention discloses a rail rolling wheel device and a seamlessly crossed steel rail matched with the same for use. The rail rolling wheel device comprises a rolling wheel, a connecting plate, a front guide wheel and a rear guide wheel, wherein the periphery of the rolling wheel is a cylindrical surface; the inner sides and the outer sides of the front guide wheel and the rear guide wheel are each provided with a wheel flange, and springs are arranged between the top of the front end of the connecting plate and a vehicle body and between the top of the rear end of the connecting plate and the vehicle body respectively. The seamlessly crossed steel rail matched with the rail rolling wheel device for use comprises two parallel first steel rail bodies and two parallel second steel rail bodies crossed with the first steel rail bodies, at the cross positions, the left ends of the second steel rail bodies are welded to the left sides of the first steel rail bodies respectively, and the right ends of the second steel rail bodies are welded to the right sides of the first steel rail bodies respectively. By means of the rail rolling wheel device and the seamlessly crossed steel rail matched with the same for use, seamless connection of crossed rails can be achieved, jolts are thoroughly avoided when rolling wheels pass through the rail crossed positions, the potential quality and safety hazards brought to carried precision objects are eradicated, and the service life of the rail is prolonged.

Description

technical field [0001] The invention relates to a track roller device and a seamless cross steel track used in conjunction with it. Background technique [0002] Flat rail car is a commonly used vehicle for machine manufacturing enterprises. It has large carrying capacity, small running frictional resistance, low cost and easy to use. However, due to the use of the ground track, sometimes it is unavoidable to intersect with the tracks of other carrying directions, which brings trouble and difficulty to the passage of the flat rail car. In order to solve this problem, the prior art, such as the Chinese invention application with the application number 201310547257.4, discloses a method for crossing the tracks of a flat car. The height determines the width and depth of the track to be cut so that the two tracks are respectively grooved on the track at the cross position to form a notch. There are several problems in this way: slotting on the track, first, bumps will occur wh...

AI Technical Summary

Problems solved by technology

There are several problems in this way: slotting on the track, first, bumps will occur when the wheels pass through the notch, which will bring quality and safety hazards to the objects carried; service life

This method also has the following problems: the connection between the conversion track and the track is still disconnected, and the first is that the wheels will still bump when they pass through the fracture, which will bring quality and safety hazards to the objects carried; The above-mentioned rotating shaft support is not suitable for the passage of flat rail cars or gantry cranes with large loads; third, the fracture reduces the strength of the track and reduces the service life of the track; fourth, a special person is required to be responsible for the rotation and switching, which increases the cost and is wrong hidden dangers of operation
