The device comprises a 1-track beam, a 2-measuring table, a 3-limit reinforcing mesh, a 4-protective fence, a 5-upper roller, a 6-guide frame, a 7-vertical limit structure, an 8-guide wheel, a 9-horizontal limit structure and a 10-ladder frame.
Detailed Description
The present invention will be described in further detail with reference to examples, but embodiments of the present invention are not limited thereto.
Example 1:
as shown in fig. 1, in this embodiment, a beam-mounted mobile measuring trolley for detecting a magnetic levitation track beam includes a measuring table 2 disposed on a track beam 1, a plurality of upper rollers 5 rotatably disposed below the measuring table 2 and in rolling connection with an upper surface of the track beam 1, a guide frame 6 disposed below the measuring table 2, and guide wheels 8 rotatably disposed on the guide frame 6 and in rolling connection with an inner side surface of the track beam 1.
The total station is installed by the measuring table 2, and the measuring work is performed by the total station. The measuring table 2 is supported by the upper roller 5, and the relative rolling of the upper roller 5 and the upper surface of the track beam 1 can drive the measuring table 2 to move along the track beam 1. The guide wheels 8 are utilized to enable the inner side surface of the track beam 1 and the guide frame 6 to mutually form a support, so that the measuring table 2 is limited to move towards the two sides of the track beam 1, the position between the measuring table 2 and the track beam 1 is kept relatively stable, the position between the total station and the track beam 1 is kept relatively stable, and the measuring precision of the total station is prevented from being influenced due to the fact that the total station and the track beam 1 transversely move relatively.
The cooperation of this scheme through last gyro wheel 5 and leading wheel 8 is used, can also realize measuring table 2 and walk along the curve section of track roof beam 1, is favorable to realizing the detection of track roof beam 1 all lines.
When detecting the whole line of the track beam 1, the trolley can be used at any position of the whole line by moving, and the measuring trolley can be erected on the track beam 1 all the time without influencing the construction of other procedures.
Example 2:
On the basis of the above embodiment, in this embodiment, the measuring table 2 is provided with a vertical limiting structure 7, and the vertical limiting structure 7 includes an a threaded rod vertically disposed and in threaded connection with the measuring table 2.
When the measuring table 2 is required to stop moving and keep static, the vertical limiting structure 7 can be utilized to play a role in locking the measuring table 2, so that the measuring table 2 is prevented from moving randomly and shaking to influence the measuring precision of the total station.
In this embodiment, the a-threaded rod is controlled to rotate downwards or upwards by rotating the a-threaded rod, and after the a-threaded rod rotates downwards to be in contact with the track beam 1, the measuring table 2 is locked by friction between the a-threaded rod and the track beam 1.
In this embodiment, an a cushion block is disposed at one end of the a threaded rod close to the track beam 1. Utilize the A cushion can increase the area of contact of A threaded rod and track roof beam 1 to increase the frictional force between A threaded rod and the track roof beam 1, improve the reliability of locking measuring table 2, and can reduce the pressure that bearing in the track roof beam 1 unit area, prevent that the surface of track roof beam 1 from receiving the extrusion of A threaded rod and damaging.
The guide frame 6 on be provided with horizontal limit structure 9, horizontal limit structure 9 include horizontal setting and with guide frame 6 threaded connection's B threaded rod.
The transverse limiting structure is utilized to better limit the transverse relative displacement between the measuring table 2 and the track beam 1, so that the position accuracy of the total station is guaranteed. When it is desired that the measuring table 2 remains stationary, a corresponding friction force is provided to enhance the reliability of locking the measuring table 2.
In this embodiment, the B threaded rod is moved in a direction approaching or separating from the track beam 1 by rotating the B threaded rod, and when the B threaded rod contacts with the track beam 1 and applies a certain pressure, the friction between the B threaded rod and the track beam 1 can be utilized to play a limiting role, thereby preventing the measuring table 2 from moving.
In this embodiment, one end of the B threaded rod, which is close to the track beam 1, is provided with a B cushion block. The contact area of the B threaded rod and the track beam 1 can be increased by utilizing the B cushion block, so that the friction force between the B threaded rod and the track beam 1 is increased, the reliability of the locking measuring table 2 is improved, the pressure born by the track beam 1 in unit area can be reduced, and the outer surface of the track beam 1 is prevented from being damaged by the extrusion of the B threaded rod.
