Problems solved by technology

Although its detection efficiency is high, the detection cost is also high; the other is a variety of small and portable rail flaw detection vehicles that are manually propelled. Although it is light and flexible, it can go up to the rail between two trains. It does not need to be dispatched by the railway department and does not delay the normal operation of the train
However, there are disadvantages such as low detection efficiency and poor detection effect.

Embodiment Construction

[0009] As shown in Figures 1 and 2, the electric rail flaw detection trolley includes a rail wheel, a vehicle frame and a rail flaw detector. Vehicle frame 2 is made of base plate, support rod and upper link, and base plate 21 is two front and back, is connected by hinge 12 between front and rear two base plates. The front, rear, left, and right sides below the base plate are equipped with rail wheels 1 respectively. Rail wheel 1 is a wheel with a rim to ensure that the trolley runs along the rails. A battery box 11 is installed on the front block base plate of the vehicle frame, and a driving motor 3 is installed on the rear block base plate. The supporting rod 22 at the back of the vehicle frame and the upper link 23 are connected by a positioning pin 4, and the front end of the upper link is bent and fixed on the front base plate. Flaw detector 10.

Abstract

The invention relates to an electric rail-defect detecting car which comprises rail wheels, a car frame and a rail-defect detector, wherein the car frame (2) comprises base plates, a support rod and an upper connecting rod; a base plate (21) is provided with a front base plate and a rear base plate, the front base plate is connected with the rear base plate (21) by a hinge (12); a battery box (11) is installed on the front base plate of the car frame, and a drive motor (3) is installed on the rear base plate; the support rod (22) behind the car frame is connected with the upper connecting rod (23) by a positioning pin (4); the front end of the upper connecting rod is fixed on the front base plate after being bent, and the front end of the base plate is fixedly connected with a detector instrument; and the rail-defect detector (10) is installed on the detector bracket. The invention has the characteristics of higher defecting efficiency and flexibility.

Description

technical field [0001] The invention relates to an electric rail flaw detection vehicle, which belongs to the technical field of rail flaw detection vehicles. Background technique [0002] The rail is the main component of the railway track. Its function is to guide the wheels of the rolling stock, bear the huge pressure of the wheels, and transmit it to the sleeper. The rails must provide the wheels with a continuous, smooth and least drag rolling surface. Therefore, in order to ensure the safe operation of the locomotive, the railway system needs to conduct flaw detection on the rails frequently to detect fatigue defects and welding defects within the rail head and rail waist (including near the joint), as well as rail bottom corrosion and crescent drop , rail head crushing and other damages, so that remedial measures can be taken in time to prevent problems before they happen. [0003] At present, there are two types of rail flaw detection vehicles in China: one is a fu...
