Abstract
A fixing device for a track measurement prism lens. The device comprises a rail fixing groove, a fixing base, leveling bubbles and a fixing bolt; wherein, the opening of the track fixing groove faces downwards and is fixed on the steel rail; the lower end of the fixed base is connected to the middle part of the top surface of the rail fixed groove, the middle part of the upper end is sunken downwards to form a central hole, and the side wall of the upper part is provided with a threaded through hole communicated with the central hole; the leveling bubble is arranged on one side of the fixed base; the fixing bolt is in threaded connection with the threaded through hole of the fixing base. The utility model provides a track measurement prism lens fixing device has following beneficial effect: the device is used for measuring the track, so that the measuring speed is greatly increased, the efficiency is greatly improved in long-term skylight measurement of an existing station, the manual operation of taking the track by using the box ruler can be reduced, and the accuracy of the measuring work is improved.
Description
Technical Field
The utility model belongs to the technical field of the railway construction equipment, especially, relate to a track measurement prism lens fixing device.
Background
At present, with the rapid development of national economy, infrastructure construction of each big city is developed in a large area, and when the scale of the existing station yard cannot meet the use requirement, reconstruction and extension construction are needed. The existing line needs to be retested before the existing station is transformed and constructed, and a total station is generally adopted for measurement during measurement. In general, a micro prism or a centering single rod is usually adopted in measurement construction, the center of an existing line is measured by using a box ruler in measurement, then the micro prism or the centering single rod is leveled, and the coordinate of the center position of the existing line is acquired. Obviously, the method has low working speed and efficiency and poor accuracy.
Disclosure of Invention
In order to solve the above problem, an object of the present invention is to provide a fixing device for a track measurement prism lens.
In order to achieve the above object, the utility model provides a track measurement prism head fixing device, which comprises a track fixing groove, a fixing base, a leveling bubble and a fixing bolt; wherein, the opening of the track fixing groove faces downwards and is fixed on the steel rail; the lower end of the fixed base is connected to the middle part of the top surface of the rail fixed groove, the middle part of the upper end is sunken downwards to form a central hole, and the side wall of the upper part is provided with a threaded through hole communicated with the central hole; the leveling bubble is arranged on one side of the fixed base; the fixing bolt is in threaded connection with the threaded through hole of the fixing base.
The track fixing groove is made of a stainless steel plate with the thickness of 2 mm and the width of 10 cm, and the inner width of the track fixing groove is the same as the width of the upper edge of the steel rail.
The utility model provides a track measurement prism lens fixing device has following beneficial effect:
the device is used for measuring the track, so that the measuring speed is greatly increased, the efficiency is greatly improved in long-term skylight measurement of an existing station, the manual operation of taking the track by using the box ruler can be reduced, and the accuracy of the measuring work is improved.
Drawings
Fig. 1 is the utility model provides a track measurement prism lens fixing device sketch.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the utility model provides a fixing device for a track measuring prism head, which comprises a track fixing groove 1, a fixing base 2, a leveling bubble 4 and a fixing bolt 5; wherein, the opening of the track fixing groove 1 faces downwards and is fixed on the steel rail; the lower end of the fixed base 2 is connected to the middle part of the top surface of the track fixing groove 1, the middle part of the upper end is sunken downwards to form a central hole, and the side wall of the upper part is provided with a threaded through hole communicated with the central hole; the leveling bubble 4 is arranged on one side of the fixed base 2; the fixing bolt 5 is screwed in the threaded through hole of the fixing base 2.
The track fixing groove 1 is made of a stainless steel plate with the thickness of 2 mm and the width of 10 cm, and the inner width of the track fixing groove is the same as the width of the upper edge of the steel rail.
Will now the utility model provides a prismatic lens fixing device is measured to track's application method explains as follows:
when the track measurement is needed, firstly, the working personnel arranges points on the steel rail according to the same distance in advance, after the points are arranged, the lower end of the prism lens 3 is inserted into a central hole of a fixed base 2 on the track measurement prism lens fixing device, and then the fixing bolt 5 is used for tightly propping and fixing the prism lens; and then clamping the opening of the track fixing groove 1 on a unilateral steel rail, installing the track measuring prism lens fixing device at a distribution position, finely adjusting the track fixing groove 1 left and right according to the leveling bubbles 4 until the bubbles in the leveling bubbles 4 are positioned at the central position, and then measuring. When in measurement, the prism lens 3 is used for collecting the position of the steel rail on one side, and the center position of the existing line is deviated on the graph in the later period.
