Problems solved by technology

[0006] The present invention is aimed at the problem that the facility of the limit device is simple, the integrity is poor, and the adjacent longitudinal girders are prone to misalignment in the lateral direction in the construction of the convenience beam. It provides a measuring device for the displacement of the D-type convenience beam and the inclination angle of the bridge pier. Using the characteristic that the liquid level is always kept horizontal, the horizontal displacement is converted into oblique displacement, which can realize the measurement of horizontal displacement and inclination angle

Embodiment 1

[0026] A measuring device for D-type beam dislocation and pier inclination, the whole device is connected to the existing components through the anchor plate 11 with connection screw holes 12 reserved, such as figure 1 As shown, it includes the outer sleeve 1, the inner sleeve 2, the telescopic rod 4 and the rotary lifting system (14, 15, 21). It is connected with the external sleeve 1, and there is a fulcrum 5 at the joint. After the D-shaped beam is dislocated and moves horizontally, it will cause the telescopic rod 4 to rotate at the fulcrum 5 at the connection part with the external sleeve 1; one end of the telescopic rod 4 passes through the telescopic rod The anchor block 6 is anchored on the inner sleeve 2, and the lifting system (14, 15, 21) includes an outer cylinder 21, a built-in rotating shaft 15, and a lifting slider 14. The outer cylinder 21 is fixed on the bottom of the outer sleeve 1, and the built-in rotating shaft 15 is fixed on the On the inner sleeve 14, wh...

Embodiment 2

[0047] The difference between this example and Example 1 is that both ends of the telescopic rod 4 are respectively connected to the inner sleeve 2 and the outer structure, and the connection point with the outer sleeve 1 is used as the fulcrum 5 to rotate. According to the principle of leverage, the distance between the outer sleeve 1 and the inner sleeve 2 is not unique. By adjusting the distance between the outer sleeve 1 and the inner sleeve 2, the fulcrum 5 of the telescopic rod 4 on the outer sleeve 1 and its connection can be changed. The length ratio of the two sides.

Embodiment 3

[0049] On the basis of Example 1, such as figure 1 As shown, the inner bottom of the outer sleeve 1 is provided with a sliding track 9, and the inner sleeve 2 is connected to the outer sleeve 1 through the spring upper anchor plate 13, the spring 8 and the lower spring anchor base 10 in turn, and the lower spring anchor base 10 Sliding in the sliding track 9, the bottom of the inner sleeve 2 is provided with a mass block 7, and the spring 8 and the mass block 7 can control the vibration of the inner sleeve 2 and its internal structure. If the spring 8 and the anchor base plate 10 under the spring 1. The anchor plate 13 on the spring constitutes a group of units, and eight groups of units can be designed, which are evenly arranged on the circular sliding track 9, further reducing the impact of vibration caused by external effects on the liquid level, which is safe and efficient.

[0050] Also comprise horizontal support bar 22 and arc block 23, as figure 2 as shown, figure ...

Abstract

The invention discloses a measuring device for D type auxiliary girder displacement and bridge pier inclination angle. The whole device is connected with existed components through anchor plates reserved with connecting threaded holes, the device comprises an external sleeve tube, an internal sleeve tube, a telescopic rod and a rotary lifting system, the telescopic rod is connected with the external sleeve tube, one end of the telescopic rod is anchored on the internal sleeve tube through an anchoring block of the telescopic rod, the internal sleeve tube rotates under the action of the telescopic rod through the rotary lifting system, a liquid box is arranged in the internal sleeve tube, the liquid box is provided with electrolyte and at least two electric pole rods, horizontal displacement is converted to inclination displacement through the rotary lifting system, the property that the liquid level maintains level is ingeniously used for indirectly measuring the displacement of an engineering structure through the variation of the length immersed in the electrolyte of the electric poles after the liquid obliques, the device has an inclination angle and displacement measuring function, the displacement measuring range is expanded by adjusting the length ratio of two sides of the pivot point of the telescopic rod, and therefore the device has a shock-absorbing controlling function.

Description

[0001] Field [0002] The present invention relates to the field of railway bridge construction, in particular, to a measuring device for D-type convenient girder dislocation and bridge pier inclination angle, and a method for measuring D-type convenient beam dislocation and bridge pier inclination angle Background technique [0003] The D-shaped beam is a common temporary structure erected to ensure the normal operation of the railway line when it is reinforced during the construction of the existing railway line. When the train acts on the convenience beam, the train load transmits the force to the crossbeam through the deformation of the track, and then to the longitudinal beam of the convenience beam through the connection between the longitudinal beam and the crossbeam. The vibration of the train causes the track to vibrate, causing the longitudinal and lateral displacement of the convenience beam, especially when erecting multiple convenience beams, the longitudinal beam...
