Track flat car and seamless cross steel track for use with it

Abstract

The invention discloses a rail flat car and seamless intersection steel rails used in fit with the same. The rail flat car comprises a car body, a pair of front rolling wheels and a pair of rear rolling wheels. A guide device is arranged in front of the front rolling wheels. A guide device is arranged behind the rear rolling wheels. A front guide wheel and a rear guide wheel are arranged at the front end and the rear end of a connection plate of each guide device. Springs are arranged between the tops of the front end and the rear end of the connection plate of each guide device, and the bottom of the car body correspondingly. The steel rails comprise the two parallel first steel rails and the two parallel second steel rails. The two parallel second steel rails and the two parallel first steel rails intersect perpendicularly. The left ends of the second steel rails are welded to the left sides of the first steel rails. The right ends of the second steel rails are welded to the right sides of the first steel rails. According to the rail flat car and the seamless intersection steel rails used in fit with the same, seamless connection of the intersection rails can be achieved, the phenomenon that bumping occurs when the rolling wheels pass the rail intersection positions is avoided completely, quality and safety potential safety hazards brought to carried precise objects are avoided completely, and thus the service life of the rails is prolonged.

Description

technical field [0001] The invention relates to a track flat car 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, there will be bumps when...

AI Technical Summary

Problems solved by technology

There are several problems in this way: slotting on the track, first, there will be bumps when the wheels pass through the slot, which will bring quality and safety hazards to the precision objects carried, and second, it will reduce the strength of the track slotting. And the roller will also collide with the end of the notch when crossing the notch of the track, which reduces the service life of the track

There are also many problems in this method: the connection between the transition track and the track is still disconnected. First, there will still be bumps when the wheels pass through the fracture, which will bring quality and safety hazards to the precision objects carried; The above-mentioned rotating shaft support is not suitable for the passage of flat rail cars or gantry cranes with a large load; third, the fracture reduces the strength of the track and reduces the service life of the track; There is a risk of misuse
