Problems solved by technology

[0013] The above four methods of height adjustment belong to the category of passive height adjustment. When the deformation of the railway bridge reaches or exceeds a certain limit, which affects the smoothness of the line, the railway maintenance department organizes relevant units to adjust the height of the support. Significant hysteresis and uncertainty
Moreover, the height adjustment operation period is long, the efficiency is low, the traffic needs to be interrupted or the operation is selected during the line operation window, and the construction cost is high

Embodiment 1

[0053] Such as Figure 7 , 8 As shown, the artificial height adjustment process of a spherical bearing is as follows: when the bridge deck height monitored by the bridge deck height monitoring system 14 reaches the height adjustment, the vertical height adjustment amount of the bearing is first set, and then the power is manually started. The source controls the vertical pushing device 11 to lift the lower seat plate 6 to a preset height (slightly 1mm higher), and completes the adjustment of the vertical height of the upper structure of the support. Manually start both sides horizontally to pushing device 13 again, adjust wedge-shaped block 9 to setting horizontal position; Then control the vertical jack in the vertical pushing device 11 of the control system to carry out jacking operation, make step block 7 drop to wedge-shaped block 9 completely Then unload the vertical force of the control system vertical thrusting device 11, and the vertical adjustment of the support is c...

Embodiment 2

[0055] Such as Figure 7 , 8 As shown, a semi-automatic height adjustment process of the height adjustment spherical bearing is: when the bridge deck height monitored by the bridge deck height monitoring system 14 reaches the height adjustment, the power source and control system are artificially installed for the height adjustment spherical bearing, Both the vertical pushing device 11 and the horizontal pushing device 13 are connected with the control system. First, set the vertical height adjustment of the support. After confirmation, start the vertical pushing device 11 of the control system, and lift the lower seat plate 6 to the predetermined level. Set the height (slightly 1mm higher) to complete the adjustment of the vertical height of the upper structure of the support. Then start the horizontal pushing device 13 on both sides of the control system, and adjust the wedge block 9 to the set horizontal position; 9, then unload the vertical power of the control system ve...

Embodiment 3

[0057] Such as Figure 7 , 8 As shown, a fully automatic height adjustment process of the height adjustment spherical bearing is as follows: when the bridge deck height monitored by the bridge deck height monitoring system 14 reaches the height that needs to be adjusted, the control system first sets the vertical height of the bearing according to the collected bridge deck information. Then the control system activates the vertical pushing device 11 to lift the lower seat plate 6 to the preset height (slightly 1mm higher), and completes the adjustment of the vertical height of the upper structure of the support. The control system starts the horizontal pushing devices 13 on both sides again, and adjusts the wedge-shaped block 9 to the set horizontal position; On block 9, unload control system vertical pushing device 11 vertical force then, and support vertically heightens and finishes. In this process, all operations are completed by the control system, which can remotely jo...

Abstract

The invention relates to a height adjusting spherical support. The height adjusting spherical support comprises a support body system, a bridge floor height monitoring system, a height adjusting system and a control system, wherein the bridge floor height monitoring system is connected with the control system; the control system controls the height adjusting system to adjust the height of the bridge floor after being jacked up by the support body system; the height adjusting system is arranged below the support body system; the height adjusting system comprises a step block, wedge blocks, a plurality of vertical jacking devices arranged at the position corresponding to the lower surface of a lower seat plate, a plurality of horizontal jacking devices connected with the wedge blocks and a bottom seat plate; when the bridge floor height monitoring system 14 monitors that the height of the bridge floor needs to be adjusted to the required height, the vertical adjusting amount of the support is set, the control system is started to control the vertical jacking devices to jack up the lower seat plate to the preset height, the horizontal jacking devices are started to adjust the wedge blocks to the horizontal position, so that the step block can completely fall onto the wedge blocks, the control system is shutdown to unload the vertical forces of the vertical jacking devices, and the vertical height adjustment of the support is completed.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, and relates to a height-adjusting spherical bearing used for adjusting the height of a bridge. Background technique [0002] Due to temperature changes, the long-span arch bridge will cause the elongation and shortening of the arch axis, which will cause the height of the arch bridge deck to change and reduce the smoothness of the bridge deck. In order to ensure the comfort of high-speed trains, the speed reduction mode is usually adopted when the train passes the arch bridge. The elevation of the arch bridge deck will change with the temperature every day. In order to control the change of the elevation of the bridge deck, a support that can adjust the height according to the change of the elevation of the bridge deck is needed. [0003] At present, there are four kinds of height adjustment support schemes adopted at home and abroad, including backing plate height adjustment, spiral ...
