Abstract
The utility model discloses a detection tool for detecting the distance between a CRTS III type finished track board end bolt hole and a board end, which is composed of a ruler, a T-shaped caliper and a central positioning member. The central positioning member is inserted into the bolt hole. The T-shaped caliper is clamped on the side wall of a track board. The horizontal plate of the T-shaped caliper clings to the top face of the track board. The top face of the horizontal plate is aligned with the top face of a rail-bearing groove of the track board. The vertical plate of the T-shaped caliper clings to the board end of the track board. The starting end of the ruler tightly abuts on the clamping corner of the T-shaped caliper. The ruler face clings to the horizontal plate and extends to the center line of the central positioning member. The detection tool has the advantages of relatively high measuring precision, simple structure and convenient operation, etc. The detection tool provided by the utility model can be widely used for detecting the distance between the CRTS III type finished track board end bolt hole and the board end.
Description
Technical field
The utility model relates to the position probing frock of the bolt hole of CRTS III type track plates production board quality testing frock, particularly a kind of production board in a kind of railway engineering.
Background technology
CRTS III type track plates plate terminal bolt hole is to determine whether qualified important indicator of Line for Passenger Transportation CRTS III type track plates production board to plate end distance.And usually only simply adopting ruler to carry out rough detection at present, its accuracy of detection is inadequate.
The utility model content
The purpose of this utility model is to provide a kind of CRTS III type track plates production board plate terminal bolt pitch-row plate end apart from detecting frock, solve the not high technical matters of routine measurement instrument measuring accuracy.
For achieving the above object, the utility model adopts following technical scheme:
A kind of CRTS III type track plates production board plate terminal bolt pitch-row plate end is apart from detecting frock, formed by ruler, T-shaped slide calliper rule and centralized positioning part, in described centralized positioning part inserting bolt hole, described T-shaped slide calliper rule are stuck in the sidewall of track plates, its transverse slat is concordant with the rail support groove end face of track plates with the end face that the track plates end face is adjacent to described transverse slat, the sidewall of its riser and track plates is adjacent to, the Ka Jiaochu that the initiating terminal of described ruler presses closer at T-shaped slide calliper rule, chi face are close to transverse slat and extend to centralized positioning part position of center line.
The length of the transverse slat of described T-shaped slide calliper rule is not less than 100mm, and thickness is 20mm, and the length of riser is not less than 330mm.
Described centralized positioning part comprises the threaded screw-in section of all-in-one-piece and termination, location, and termination, described location is arranged on the top that screws in section, and both are coaxial, described diameter and screw thread and the bolt hole coupling that screws in section.
The described length 112mm that screws in section, the termination, location is column type, diameter is 40mm, is highly 30mm.
Compared with prior art the utlity model has following characteristics and beneficial effect:
The utility model is by arranging the centralized positioning part, the center of keyhole is caused the termination, location, can directly annotate position of center line at termination, location lateral marks, by the distance of measurement and positioning termination center line to edges of boards, indirectly measure keyhole to the distance of edges of boards, measuring accuracy is relatively high, need not complicated auxiliary mould is set, and is simple in structure.In addition, this device is easy to operate, can repeated multiple timesly use.
The utility model can be widely used in CRTS III type track plates production board plate terminal bolt pitch-row plate end apart from detecting frock.
