Embodiment Construction

[0022] see Figure 1 to Figure 3 , the present invention provides a detection device for measuring the flatness and sphericity of a bridge support, comprising a Y-shaped fork 1, a dial gauge 6, a positioning pin 7, a first locking pin (not shown) and a second Locking pin 8.

[0023] The Y-shaped fork 1 is a three-sided component in a Y-shape, and the three sides of the Y-shaped fork 1 are 120° to each other, and the lengths of the three sides are equal.

[0024] Preferably, the top and side walls of the three sides of the Y-shaped fork 1 are rounded to prevent bumps and scratches during use.

[0025] At the center of the Y-shaped fork 1, there is a dial gauge installation hole 2 vertically through, for inserting the dial gauge 6 therein for detection. On the side wall of the junction of any two sides of the Y-shaped fork 1, a horizontal dial gauge locking hole 3 is provided. After the dial gauge 6 is inserted into the dial gauge mounting hole 2, use the first locking pin (in...

Abstract

The invention discloses a detection device for measuring planeness and sphericity of a bridge support, which comprises a Y-shaped fork, a dial indicator, a positioning pin, a first locking pin and a second locking pin, and is characterized in that the whole Y-shaped fork is Y-shaped, and the center of the Y-shaped fork is provided with a vertically through dial indicator mounting hole for inserting and mounting the dial indicator; a horizontal dial indicator locking hole is formed in the side wall of the intersection of any two sides and used for inserting a first locking pin to fix a dial indicator, a plurality of vertically-through positioning holes are formed in three sides of the Y-shaped fork and used for inserting positioning pins, a plurality of horizontally-through locking holes are formed in the side walls of the three sides corresponding to the positioning holes and used for locking the dial indicator, and the second locking pin is inserted to fix the positioning pin. The device is simple in structure, convenient, efficient and wide in application range, loss of the support is reduced, the test result is more accurate, and therefore the overall efficiency of the support test is improved.

Description

technical field [0001] The invention relates to the technical field of detection of physical properties of supports, in particular to a detection device for measuring flatness and sphericity of bridge supports. Background technique [0002] The spherical bearing is a bridge bearing product composed of upper bearing plate, lower bearing plate, spherical crown lining plate, flat PTFE plate and spherical PTFE plate. However, there is currently a lack of professional testing tools for testing the flatness and sphericity of spherical bearings, which affects the test efficiency. [0003] The invention is used to measure the sphericity of the spherical crown lining plate and the spherical polytetrafluoroethylene plate of the spherical support and the flatness of the flat polytetrafluoroethylene plate, and can be flexibly adjusted to facilitate the measurement of spherical support components with different diameters . In addition, the operation is convenient, the accuracy is high,...
