Description

The utility model relates to hoisting-and-transport machines, in particular, to devices for maintaining the axial direction of movement of the wheels along the rail with the simultaneous measurement of deviations of the rail track.

Known two-wheeled trolley with a device for measuring rail deviations, made in the form of scissors, at both ends of which springs and side rollers are installed [1, figure 2, 3]. The disadvantage of this device is the joint (dependent) adjustment of the distance between the rail and the side rollers, as a result of which the side rollers at one end of the scissors will not be pressed against the rail, since they are pressed by the side rollers on the other end of the scissors. The gap between the side rollers and the rail will open in case of deviations in the width of the rail head. Therefore, the two-wheeled trolley will have a deviation of the axial direction when the wheels move, causing an error in the measurement of the crane path.

Known guide roller device for cranes with separate adjustment of the distance between the rail and the side rollers due to the eccentric and splines [2, Fig. 3]. To this end, gear rims are provided, made on the eccentric axis of the side rollers. The disadvantage of this device is that in the case of local reduction in the width of the rail (as a result of its wear), there will be a lateral gap between the side rollers and the rail, causing an error in the measurement of the crane path and additional adjustment of the side rollers will be required.

The purpose of the invention: improving the accuracy of the movement of the measuring two-wheeled cart relative to the axis of the rail.

The proposed measuring two-wheeled trolley contains a frame, two wheels, upper and lower scissors, and springs are installed on the arms of the upper and lower scissors, and the working ends of the upper and lower scissors containing side rollers are connected to the arms of the upper and lower scissors by means of an angular adjuster.

In FIG. 1 shows a measuring two-wheeled trolley - the main view; in FIG. 2 - top view; in FIG. 3 is a plan view (lower scissors not shown); in FIG. 4 is a plan view (upper scissors not shown); in FIG. 5 - section aa along the angular regulator; in FIG. 6 - section BB on the angular regulator: 1 - the working end of the scissors; 2 - an angular regulator; 3 - spring; 4 - scissors handle; 5 - side roller; 6 - rail; 7 - counterweight; 8 - two-wheeled frame; 9 - axis of scissors; 10 - a nut; 11 - splined shaft.

Measuring two-wheeled trolley operates as follows. The working ends of the scissors 1 are set using angle adjusters 2 so that the spring 3 of the scissor arms 4 creates a significant force of the side rollers 5 on the side surfaces of the rail 6. Then the two-wheeled trolley is moved along the rail 6. The counterweights 7 give a stable balance to the two-wheeled frame 8. The axis of the scissors 9 keeps the upper and lower scissors in balance. At the working end of the scissors 1 and the scissors handle 4 of the angle adjuster 2 there are slots. To change the angle of inclination of the working end of the scissors 1 relative to the handle of the scissors 4, unscrew the nut 10, remove the working end 1, turn it onto one or more slots of the handle of the scissors 4, then the splined shaft 11 is fixed with the nut 10.

The use of a measuring two-wheeled trolley, angle adjusters with independent adjustment of the pressing force of the upper side rollers and scissors allows you to save the direction of movement of the measuring device (installed on the measuring two-wheeled trolley) strictly along the axis of the rail. This increases the accuracy of measuring deviations of the rail axis and measuring deviations of the width of the rail head.
