the specific using operation steps of the metering and detecting vehicle are as follows:

step one, a machine shell installation hole under a total station (31) is aligned with a limiting inserting plate (26) and pressed downwards, a buckle (28) is connected with the limiting inserting plate (26) in a rotating mode, the tail end of the buckle (28) is connected with a compression spring (27), when the buckle (28) is acted by a force from the total station (31), the compression spring (27) at one end of the buckle (28) deforms and continuously contracts towards a component groove of the limiting inserting plate (26), the buckle (28) moves towards the component groove during contraction until the buckle (28) is completely positioned in the component groove, the limiting inserting plate (26) and the buckle (28) are completely inserted into the machine shell installation hole, the machine shell installation hole is communicated with a buckling hole (21), in the process of pressing downwards the total station (31), the height position of the buckle (28) in the machine shell installation hole continuously changes until the buckle (28) corresponds to the position of the buckling hole (21), the space limitation low buckle (28) of the machine shell installation hole is released, the buckle (28) is ejected out of the buckling hole (21) under the influence of the reducibility of the spring, so that the limiting effect on the total station (31) is completed, and the fixed installation operation of the total station (31) is completed;

secondly, in order to ensure that the horizontal state of the total station (31) can swing the angle of the adjusting rod (24) by twisting the first bolt (23) so as to facilitate the total station (31) to achieve the optimal horizontal effect, when the position of the total station (31) needs to be adjusted under the condition of not changing the position of the detection vehicle, the first motor (5) clockwise drives the screw rod (6) to rotate, the mechanism connecting plate (8) in threaded connection with the screw rod (6) upwards generates position change, so that the total station (31) on the mechanism connecting plate (8) and the total station (31) are changed to generate height position change, when the first motor (5) anticlockwise rotates, the screw rod (6) rotates to drive the mechanism connecting plate (8) and the total station (31) to downwards move, the total station (31) is arranged on the second motor (13) through the fixed base (14), and the second motor (13) generates driving force to enable the driving wheel (16) to rotate, the driving wheel (16) always rotates in the same direction to control the transverse moving direction of the total station (31) during rotation;

and thirdly, swinging the protection plate (19) backwards to be in a horizontal state with the ground, inserting one end of the inclined stay bar (33) which swings upwards to the inclined stay bar (33) into the limiting groove (20) of the protection plate (19), and forming an included angle between the inclined stay bar (33) and the limiting rod (10) to finish the supporting effect of the inclined stay bar (33) on the protection plate (19).

2. The building traffic measurement and detection vehicle according to claim 1, wherein the total station (31) has a housing mounting hole formed at a bottom end thereof and a fastening hole (21) formed at a rear end thereof, the fastening hole (21) is communicated with the housing mounting hole, and an aperture of the fastening hole (21) is larger than a dimension of the fastener (28).

3. The building traffic measurement detection vehicle as claimed in claim 1, wherein the number of the inclined supporting rods (33) is two, the inclined supporting rods (33) are symmetrically arranged on the lifting limiting column (32), and the inclined supporting rods (33) can be rotatably abutted with the limiting grooves (20) of the protection plate (19).

4. The building traffic measurement detection vehicle according to claim 1, wherein a compression spring (27) is fixedly mounted at the movable end of the buckle (28), and the buckle (28) and the compression spring (27) are both positioned in a part groove of the limiting insertion plate (26).

5. The building traffic measurement detection vehicle as claimed in claim 1, wherein the number of the driving wheels (16) is three, two driving wheels (16) are positioned in the upper end groove of the fixed cross bar (7), one driving wheel (16) is positioned in the lower end groove of the fixed cross bar (7), the wheel lever of each driving wheel (16) is connected with a driven gear (29), and the three driven gears (29) are meshed with the driving gear (30).

6. The construction traffic measurement detection vehicle according to claim 1, wherein the mechanism connecting plate (8) is provided with internal threads, and the mechanism connecting plate (8) is formed by assembling and fixing two triangular plates through screws.

7.
