Abstract

The utility model discloses a portable demountable rail-defect detector car frame which comprises a driving axle, a driven axle and a car frame base framework. Driving wheels are arranged at the two ends of the driving axle, a driving axle bag is connected between the two driving wheels, driven wheels are arranged at the two ends of the driven axle, the car frame base framework is arranged on the driving axle and the driven axle, fixed bases (8) matched with the lower end face of a left component, the lower end face of a right component, the upper end face of the driving axle and the upper end face of the driven end face respectively are in clamping connection between the front end portion and the rear end portion of the left component of the car frame base framework (1) and the driving axle and the driven axle and between the front end portion and the rear end portion of the right component of the car frame base framework (1) and the driving axle and the driven axle respectively, locking bases (9) matched with the upper end face of the left component and the upper end face of the right component are in clamping connection with the upper end faces, corresponding to the fixed bases, of the left component and the right component respectively, and U-shaped screw rods (7) penetrate through screw holes formed in the fixed bases and screw holes formed in the locking bases from bottom to top from the lower end face of the driving axle and the lower end face of the driven axle and are connected and fixed through nuts. The safety and the stability of a rail-defect detector car in on-rail detection are improved.

Description

A kind of portable removable rail examination vehicle carriage

Technical field

The utility model relates to a kind of portable dismantled and assembled rail examination vehicle carriage, belongs to the rail flaw detection car field.

background technology

Rail flaw detection car is near survey (comprising joint) in the rail head of rail and web of the rail scope tired defect and weld defect, and flange of rail corrosion and crescent moon fall the special-use vehicle equipment of piece, crushing of rail head equivalent damage situation.

The various small-sized and portable rail inspection car of domestic artificial propelling at present, though it has small and exquisite, characteristics flexibly, but because it is to carry out the rail examination detection between the gap of two row trains, and its complete vehicle weight is generally also more than 100 kilograms, once, therefore emergency situation occurs, be difficult to and rail at present, thereby exist the potential safety hazard detected in-orbit.

The disclosed a kind of electric rail-defect detecting car of Chinese patent 201020177777.2, its vehicle frame consists of base plate, strut bar and upper connecting rod, base plate is two of front and back, between the base plate of two of front and back by chain connection.Though it is divided into two car from centre, there are the characteristics of fast assembling-disassembling, maneuverability, but still need two, three people to coordinate the upper and lower track of ability piecemeal; And the structure of this base plate has also caused the less stable of inspection car.

the utility model content

The purpose of this utility model is to provide a kind of dismounting safely and fast of both being convenient to, and can keep again the portable removable rail examination vehicle carriage of whole vehicle stability.

Its technical scheme is: a kind of portable dismantled and assembled rail examination vehicle carriage, comprise two ends install drive wheel and between connect the drive axle of drive axle bag, the driven bridge of flower wheel is installed at two ends, be arranged on the vehicle frame bedframe on drive axle and driven bridge, it is characterized in that: a described vehicle frame bedframe left side, before the member of right both sides, between rearward end and drive axle and driven bridge, one of clamping and left respectively, member lower surface, right both sides and the permanent seat matched with drive axle and driven bridge upper surface, a left side corresponding with permanent seat, on member upper surface, right both sides, one of clamping and left respectively, the locking bed that member upper surface, right both sides matches, U-shaped screw rod is the screw of offering through permanent seat and locking bed from bottom to top from the lower surface of drive axle and driven bridge respectively, by nut, be connected and fixed.

Its technique effect is: owing to the rail examination vehicle carriage being divided into to removable three parts of drive axle, driven bridge and bedframe, thereby further divide the weight that has subtracted each several part, the weight of drive axle and driven bridge portion particularly, only a people can easily lift lower railway, has improved the safety that rail flaw detection car detects in-orbit; Simultaneously, adopt permanent seat, locking bed, U-shaped screw rod and nut to be connected and fixed bedframe, improved the stability of rail flaw detection car.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the upward view of Fig. 1.

The specific embodiment

As shown in Figure 1, 2, a kind of portable removable rail examination vehicle carriage, comprise two ends install drive wheel 2 and between connect drive axle bag 4 drive axle, the driven bridge 12 of flower wheel 3 is installed at two ends, is arranged on the vehicle frame bedframe 1 on drive axle and driven bridge 12.Described vehicle frame bedframe 1 left side, before the member of right both sides, between rearward end and drive axle and driven bridge 12, one of clamping and left respectively, member lower surface, right both sides and the permanent seat 8 matched with drive axle and driven bridge upper surface, a left side corresponding with permanent seat 8, on member upper surface, right both sides, one of clamping and left respectively, the locking bed 9 that member upper surface, right both sides matches, U-shaped screw rod 7 is the screw of offering through permanent seat 8 and locking bed 9 from bottom to top from the lower surface of drive axle and driven bridge respectively, by nut, be connected and fixed, thereby vehicle frame bedframe and drive axle and driven bridging are connect and form an integral body.

Claims

1. a portable removable rail examination vehicle carriage, comprise two ends install drive wheel and between connect the drive axle of drive axle bag, the driven bridge of flower wheel is installed at two ends, be arranged on the vehicle frame bedframe on drive axle and driven bridge, it is characterized in that: described vehicle frame bedframe (a 1) left side, before the member of right both sides, between rearward end and drive axle and driven bridge (12), one of clamping and left respectively, member lower surface, right both sides and the permanent seat (8) matched with drive axle and driven bridge upper surface, a left side corresponding with permanent seat, on member upper surface, right both sides, one of clamping and left respectively, the locking bed (9) that member upper surface, right both sides matches, U-shaped screw rod (7) is the screw of offering through permanent seat and locking bed from bottom to top from the lower surface of drive axle and driven bridge respectively, by nut, be connected and fixed.
