Description

Track center coordinate measuring device

Technical Field

The utility model belongs to the field of railway engineering measurement equipment, and particularly relates to a track center coordinate measurement device.

Background

The central coordinates of the measuring track are used for fitting the shape of the existing railway, serve as the basis for generating the existing line theoretical center and designing the position of the second central line, are an important work indispensable in the measurement of the existing railway, and are first hand data for developing subsequent design work. When the central coordinate of the track is measured, the linear road section is generally measured at 40 meters, the curve is measured at 20 meters, the average distance per kilometer is about 25 to 50, the time required for the measurement is long, the workload is large, and at least two people are generally required. The time required for measuring the existing railway line is limited due to the short time required for the sunroof (for adjusting the train operation plan and for providing the construction and maintenance).

The current method for measuring the center coordinates of the existing linear section track is to utilize an insulating square ruler to conduct pulling distance separation on the left steel rail and the right steel rail according to the measuring mileage of the railway, and then to find out the center point of the track on the ground by using a plumb bob and measure by using a centering rod. The traditional method requires the operator to frequently squat down and the process is tedious. Because the railway measurement operation condition is special, the personnel for construction and measurement often need to quickly go down the road according to the safety protection requirement; however, the existing RTK mobile station has a slow measurement speed in the measurement process, and cannot reduce the influence on the track signal and achieve a device which rapidly leaves the track.

Disclosure of utility model

Aiming at the problems that the existing RTK mobile station has low measurement speed in the measurement process, cannot reduce the influence on a track signal and can rapidly leave the track, the utility model provides a track center coordinate measurement device.

In order to achieve the technical purpose, the utility model adopts the following technical scheme:

A track center coordinate measuring device comprises an RTK mobile station and a mobile trolley carrying an RTK mobile station body; the travelling car carrying the RTK mobile station body comprises a train wheel, a mounting plate, an RTK base, an armrest and a handle;

The train wheels are arranged on two sides of the mounting plate, and the width between the two train wheels is the same as the width of the rail;

the front end of the mounting plate is fixed with a handle, and the rear end is fixed with a handrail;

The upper end of the mounting plate is connected with an RTK base through a plastic pipe, and an RTK mobile station is mounted on the RTK base.

Further, the train wheel was a rubber train wheel 217.5mm thick.

Further, the mounting panel is 400 by 1000 mm's PVC insulation board, and PVC insulation board is perpendicular to install a solid rigid plastic pipe apart from the trompil of wheel outside 717.5mm department, and solid rigid plastic pipe is connected with RTK base.

Further, the armrest is a wooden armrest, and a handbook support is arranged on the wooden armrest and used for placing an RTK handbook; the RTK mobile station is connected with the RTK handbook through Bluetooth. The operating handbook may control the RTK mobile station to operate.

Further, the RTK base is a blister base.

When measuring, only the measuring personnel pushes the trolley to reach the target mileage, the base with the bubble is adjusted, and when the bubble is centered, the measuring key of the hand book is clicked to measure.

When the vehicle is required to go up and down, the wooden handle is held by one hand, and the trolley can be easily carried by holding the handrails by the other hand.

Compared with the prior art, the utility model has the following beneficial effects:

the measurement speed of the central coordinate of the existing line track is effectively improved.

The measuring process is simplified, the number of measuring personnel is reduced, and the labor intensity of the personnel is lightened.

The device is made of light materials, has low cost and small weight, can be operated by a single person, and can be rapidly moved on and off.
