The utility model has the characteristics of simple structure, low cost, convenient operation and the like, and is suitable for detecting the positioning net sheet of the railway box girder steel bar engineering. When the device is used, firstly, the horizontal ruler below the device is in a horizontal state, the height of the vertical telescopic graduated scale is adjusted according to the positioning meshes with different heights installed on the beam body, the convex sliding wheel is used for moving the horizontal telescopic graduated scale up and down, the Y coordinate can be accurately read out, and the X coordinate can be accurately read out when the horizontal telescopic graduated scale is adjusted. The coordinates of the box girder positioning net piece can be accurately detected by adjusting the telescopic graduated scale. The device has simple structure and convenient operation; the labor is saved, the efficacy is improved, and the construction cost is reduced; the deviation condition of the site construction positioning coordinates can be clearly and intuitively reflected, the adaptability is strong, and the practical effect is good.
Description
Technical Field
The utility model belongs to the field of railway box girder steel bar engineering construction, and particularly relates to a railway box girder positioning net piece detection device.
Background
In the present high-speed railway engineering, the post-tensioning method prestressed simply supported box girder has simple stress and attractive appearance, and is widely applied to railway construction. The post-tensioning prestressed concrete box girder is mostly formed by adopting rubber rods, and the rubber rods are generally fixed by adopting a positioning reinforcing steel mesh device. However, in the process of installing the positioning net sheet, the positioning coordinates are difficult to control, the lofting control and rechecking time is long, more people need to cooperate to carry out the work, and the workload is large.
In view of the above problems, how to solve the defects of long detection time, complicated detection and the like, a railway box girder positioning net sheet detection device is needed to solve the above problems.
Disclosure of Invention
In order to solve the problems, the utility model aims to provide a railway box girder positioning net piece detection device. The device has the characteristics of simple structure, low cost, easiness in operation, universality and the like.
The utility model provides a railway box girder location net piece detection device, includes vertical flexible scale 1, horizontal flexible scale 2, horizon rule 3, protruding movable pulley 4, its characterized in that, vertical flexible scale 1 is connected horizontal flexible scale 2 through protruding movable pulley 4 and concave type sliding tray, utilizes protruding movable pulley 4 free regulation horizontal flexible scale 2 to make it detect the coordinate of every pore respectively, and horizontal rule 3 is installed to vertical flexible scale 1 below, makes wholly be in the horizontality, accurate reading.
The side surface of the vertical telescopic graduated scale 1 is provided with a concave sliding groove from top to bottom, is tightly contacted with the convex sliding wheel 4, and slides smoothly.
The transverse telescopic graduated scale 2 and the convex sliding wheel 4 are fixed by screws without gaps.
The horizontal ruler 3 is tightly attached to the vertical telescopic graduated scale 1 in a seamless welding mode, and is detected by a right angle ruler, and is strictly controlled to be 90 degrees vertical.
The beneficial effects of the utility model are as follows:
the coordinates of the box girder positioning net piece can be accurately detected by adjusting the telescopic graduated scale.
