Example Embodiment

[0052] Example 1

[0053] Such as Figure 7 , 8 As shown, a manual height adjustment process of a height-adjusting spherical support is: when the bridge deck height monitored by the bridge deck height monitoring system 14 reaches the height that needs to be adjusted, first set the support vertical height adjustment amount, and then manually start the power The source controls the vertical pushing device 11 to push up the lower seat plate 6 to a preset height (a little higher than 1mm) to complete the adjustment of the vertical height of the upper structure of the support. Then manually start the horizontal pushing devices 13 on both sides, adjust the wedge block 9 to the set horizontal position; then control the vertical jacks in the vertical pushing device 11 of the control system to perform jacking and landing operations, so that the step block 7 completely falls to the wedge block 9 Then, the vertical force of the vertical pushing device 11 of the control system is unloaded, a...

[0054] Example 2

[0055] Such as Figure 7 , 8 As shown, a semi-automatic height adjustment process of the height adjustment ball bearing is: when the bridge deck height monitored by the bridge deck height monitoring system 14 reaches the height that needs to be adjusted, the power source and control system are installed for the height adjustment ball bearing manually, The vertical jacking device 11 and the horizontal jacking device 13 are both connected to the control system. First, set the vertical height adjustment of the support. After confirmation, start the vertical jacking device 11 of the control system to lift the lower seat plate 6 to the preset 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, adjust the wedge block 9 to the set horizontal position; then control the vertical jack in the vertical pushing device 11 ...

Example Embodiment

[0056] Example 3

[0057] Such as Figure 7 , 8 As shown, a fully automatic height adjustment process of the height adjustment ball bearing is: when the bridge deck height monitored by the bridge deck height monitoring system 14 reaches the height required, the control system first sets the support vertical 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 (a little higher by 1mm) to complete the vertical height adjustment of the upper structure of the support. The control system then activates the horizontal pushing devices 13 on both sides to adjust the wedge block 9 to the set horizontal position; then the control system controls the vertical jacks in the vertical pushing device 11 to perform jacking and landing operations, so that the step block 7 is completely dropped to the wedge shape Then the vertical force of the vertical pushing device 11 of the control...

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 ...
