Description

Multifunctional existing line railway measuring square ruler

Technical Field

The utility model relates to a railway circuit measures technical field, concretely relates to multi-functional existing line railway measures square ruler.

Background

The existing railway measurement comprises mileage measurement, elevation measurement and curve center line measurement; in the measuring process, mileage measurement is firstly carried out, mileage measurement is carried out after the mileage is determined, the mileage is determined by using center line measurement instead of the mileage measurement in a curve section, and the center position of a line is determined. In the operation process, 14 persons need one total station instrument (comprising a rotating point device and a prism), one leveling instrument (comprising two sliding rulers) and one steel ruler.

In actual operation, due to the fact that the curve is ultrahigh, the outer strand of the curve is higher than the inner strand of the curve, the square ruler cannot accurately position the center position of the line, and mileage measurement at the center of the curve is inaccurate; meanwhile, the curve elevation measurement is based on the center strand, and the prism is placed in the center of the line, so that the elevation measurement function of the total station cannot be realized; because the existing square ruler has a certain width, and the prism is arranged at the transverse center of the square ruler, the center position (with a half square ruler width difference) cannot be accurately marked on the steel rail.

Therefore, in order to simplify the measurement process of the existing railway line, the multifunctional square ruler is designed, the requirements of measuring the mileage in the center of the line, measuring the plane coordinate position of the center of the line and measuring the rail surface elevation of the line can be met, the insulation performance and the point identification function are required to be met, and the multifunctional existing railway line measurement square ruler is particularly important.

The utility model discloses a realize above-mentioned purpose and specifically adopt following technical scheme:

multi-functional existing line railway survey square ruler, including the square ruler, the groove of accomodating has been seted up to the inside of square ruler, the inside of accomodating the groove is rotated and is installed the jackshaft, the outside of jackshaft is provided with the intermediate lever of pegging graft in accomodating the groove, the top of intermediate lever is provided with observes horizontally bubble, the inside of intermediate lever is provided with adjusting device, adjusting device can the quick adjustment intermediate lever level.

Further, adjusting device is including setting up the bottom plate in square ruler bottom, the nut hole has been seted up to the inside of bottom plate, the inner wall in nut hole rotates installs the pivot, the inside of pivot is provided with the nut, the inside rotation of intermediate lever installs the screw rod with nut threaded connection.

Furthermore, the thread space between the screw and the nut is large.

Further, the distance from the axis of the screw to the top end of the square ruler is 717.5mm.

Further, the distance from the axis of the middle shaft to the top end of the square ruler is 1435mm.

Furthermore, a U-shaped device is arranged at the center of the top end of the square ruler, a gap is formed in the middle of the U-shaped device, and the width of the gap is 5mm.

The utility model has the advantages as follows:

1. the utility model discloses, only with this device alright measure out circuit horizontal center, elevation, mileage, very big has played the function of this device, has improved the operating efficiency simultaneously, reduces operation personnel 43%, has reduced labour cost.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solutions in the embodiments of the present invention.

As shown in fig. 1-5, multi-functional existing line railway measures square ruler, including square ruler 1, the groove of accomodating has been seted up to square ruler 1's inside, the inside rotation of accomodating the groove installs jackshaft 3, the outside of jackshaft 3 is provided with intermediate lever 4 of pegging graft in accomodating the groove, the top of intermediate lever 4 is provided with observes horizontally bubble 5, the inside of intermediate lever 4 is provided with adjusting device, adjusting device can the 4 levels of quick adjustment intermediate lever, square ruler 1 adopts insulating processing with rail contact segment, improve device safety in utilization.

The level of the middle rod 4 can be quickly adjusted through the adjusting device, each measuring point of the middle prism of the square ruler 1 is located at the position with the same height as the line center position and the inner thigh rail surface height, and the X, Y and Z coordinates of the line center can be measured at one time through the total station.

As shown in fig. 2, in some embodiments, the adjusting device includes a bottom plate 6 disposed at the bottom of the square ruler 1, a nut hole 7 is formed in the bottom plate 6, a rotating shaft 9 is rotatably mounted on the inner wall of the nut hole 7, a nut 8 is disposed inside the rotating shaft 9, and a screw 10 in threaded connection with the nut 8 is rotatably mounted inside the intermediate rod 4.
