In order to solve the technical problems, the invention adopts the technical scheme that: an apparatus for inspecting railway construction limits, comprising a limit detector disposed on a rail;

the boundary detector comprises a leveling base, a leveling bolt, a scale rod, a sliding handle, a fixing support, a laser range finder, a horizontal bubble and an angle meter, wherein the leveling base is used for being clamped and fixed with the rail;

the goniometer comprises a fixed dial fixedly connected with the sliding handle and a rotary pointer disc arranged on the fixed support.

Further, the leveling base includes the base, sets up connecting block on the base perpendicularly, two connecting rods that are connected through activity rivet and connecting block level, the leveling bolt sets up the one end of keeping away from the connecting block at the connecting rod perpendicularly, leveling bolt also has two.

Furthermore, the scale rod is made of an aluminum alloy material.

Furthermore, the sliding handle is a pressing type sliding handle.

Furthermore, the fixed support is a spring compression type fixed support.

Furthermore, the scale range of the scale rod is 0-1250 mm.

Compared with the prior art, the invention has the beneficial effects that: one of them, at the in-process of work, can place the base on the track earlier for the bottom and the rail of base are hugged closely, can make simultaneously to set up two leveling bolts on two connecting rods adjust, make the horizontal bubble placed in the middle, ensure that the range finding pole is vertical, thereby guarantee that laser range finder's direction and railway are perpendicular, and then guarantee that the distance of measuring is accurate.

Secondly, because the highest scale of the scale rod is 1250mm, the laser range finder arranged on the scale rod can directly measure the distance between the railway track and an object outside the railway track at the height of less than 1250mm, and whether the limit requirement is met is judged according to a railway building limit diagram; when the distance between the track and an object with the height of 1250mm on the outer side of the track needs to be measured, the fixed support can be rotated, the rotation angle is read by the angle meter, the slope distance is laterally obtained by the distance meter, the height of a measuring point and the horizontal distance are calculated according to the slope distance and the angle, and whether the requirement of a limit is met or not is judged according to a railway building limit diagram.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 6, an apparatus for inspecting railway construction boundaries includes a boundary detector 15 disposed on a rail;

the boundary detector 1515 comprises a leveling base 1 used for being clamped and fixed with a track, a leveling bolt 2 arranged at one end of the leveling base 1 far away from the track, a scale rod 3 vertically arranged on the leveling base 1, a sliding handle 4 arranged on the scale rod 3, a fixed support 5 in rotation self-locking connection with the sliding handle 4, a laser range finder 6 arranged on the fixed support 5, a horizontal bubble 7 arranged in the sliding handle 4 and an angle meter 8 used for measuring an angle;

the goniometer 8 comprises a fixed dial 9 fixedly connected with the sliding handle 4 and a rotary pointer plate 10 arranged on the fixed support 5.

Leveling base 1 includes base 11, the connecting block 12 of perpendicular setting on base 11, two connecting rods 14 that are connected through activity rivet 13 and connecting block 12 level, leveling bolt 2 sets up the one end of keeping away from connecting block 12 at connecting rod 14 perpendicularly, leveling bolt 2 also has two.

The base 11, the connecting block 12 and the connecting rod 14 are all connected by angle steel welding or bolts.

The scale rod 3 is made of aluminum alloy materials.

The sliding handle 4 is a pressing type sliding handle.

The laser range finder 6 can slide up and down and be locked by pressing the sliding handle.

The fixed support 5 is a spring compression type fixed support.
