Description

Measuring tool for measuring movable rail fork

Technical Field

The application relates to the technical field of measuring scales, in particular to a measuring tool for measuring a movable rail fork.

Background

A steel rail turnout is a line connection device for switching a rolling stock from one track to another, and is usually laid in large quantities at a station or a marshalling yard. The turnout can give full play to the passing capacity of the line. Even if a single-track railway is used, a turnout is paved, and a section of fork line with the length larger than that of a train is constructed, so that the train can be split. Frog is an important component of steel rail turnout and is used to protect the wheel from safely passing through the intersection of two tracks. The height difference of the point rail and the wing rail of the fixed frog is related to the matching property of the contact of the wheels of the train and the frog, and the service life of the frog is directly influenced.

The installation height of a center rail and a wing rail at the position of a railway rail fork needs to be detected during frog installation construction, and the degree of abrasion of the center rail and the wing rail at the position of the railway rail fork needs to be detected in the daily rail operation and maintenance process. The compliance of the point rail and the wing rail is an important detection item for ensuring smooth passing of wheels and safe running of a train.

At present, most of commonly used measuring tools are fixed special measuring tools, namely, a measuring ruler is located at a fixed position of a measuring tool, and after the measuring tool is placed on a detection datum plane, data at the fixed position are measured through the measuring ruler. In daily maintenance and detection, workers need to regularly and repeatedly detect the abrasion degree of the center rail and the wing rail at the frog. The fixed measuring tool can only detect the abrasion condition of a certain single position, such as the abrasion of the point rail. The multi-point detection cannot be simultaneously met, and the common measurement cannot be carried out when the point rail and the wing rail are measured. In order to detect the wear of the point rail and the wing rail at the same position, other measuring tools need to be replaced. Therefore, maintenance personnel are required to be equipped with a plurality of measuring tools simultaneously to complete the work, and for maintenance personnel who go out to work, carrying a plurality of measuring tools is a great burden.

At this time, the interval between the first latch 41 and the second latch 42 corresponds to the height between the upper and lower sides of the beam 11, and the latches are connected to the body of the beam 11 through the upper and lower sides. That is, one side of the first latch 41 and the second latch 42 can be connected to the reader 21; the first latch 41 and the second latch 42 have a space therebetween, and the beam 11 is in contact with and held by the first latch 41 and the second latch 42 via the space. The catch member can be movably formed with the beam 11 to enable the reader 21 to move along the length of the beam 11. Wherein, a sliding cavity is provided at the opposite side of the first latch 41 and the second latch 42, and a ball 43 is provided in the sliding cavity, and the ball 43 can slide in the sliding groove 12.

During measurement, firstly, the lower side surfaces of two ends of the beam frame 11 are used for finding positioning reference, then the position of the measuring rod 22 in the vertical direction is moved to enable the measuring rod to collide with the upper surface of a core rail or a wing rail to be measured, and the abrasion data of the top surface of the core rail can be obtained through reading. The lower surfaces of both ends of the beam frame 11 have the same height, and the reference surfaces on both sides of the beam frame 11 have the same height when the beam frame is detected, thereby ensuring the reliability of the detection data.

The difference from embodiment 1 is that a retaining member is integrally provided on the side of the reader 21 adjacent to the beam 11. The reader 21 needs to be specially customized.

Example 3

The embodiment discloses a movable measuring tool for measuring a rail fork. Reference is made to fig. 7-10.

The difference from embodiment 1 is that a mounting groove 13 is formed in the front side of the beam frame 11 along the length direction, a linear slide rail 51 is fixedly mounted in the mounting groove 13, rolling grooves 53 are formed in the upper side and the lower side of the linear slide rail 51, and the rolling grooves 53 of the linear slide rail 51 are respectively matched with the first fixture block 41 and the second fixture block 42, so that the first fixture block 41 and the second fixture block 42 are clamped on the linear slide rail 51 and can move along the linear slide rail 51 in two directions. At this time, the distance between the first latch 41 and the second latch 42 is equal to the height between the upper side and the lower side of the linear slide 51,
