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

[0051] When using this patent for manual height adjustment, when the bridge deck height monitoring system 15 detects that the deviation between the bridge deck height and the reference height reaches the set threshold value, the vertical height adjustment of the support needs to be set through the calculation of the detection data of the bridge deck height monitoring system 15 start the vertical pushing device 10, lift the lower seat plate 5 to the preset height by the jack, and complete the adjustment of the vertical height of the upper structure of the support. The end structure B602 double helix structure is separated, and the vertical load of the support is carried by the jack. After the vertical height adjustment is completed, manually start the horizontal worm gear transmission mechanism, the servo motor 10 drives the worm 8 to rotate, the worm 8 drives the worm wheel 7, and the worm wheel 7 rotates with the inner and outer double helix end surface structure B602 until th...

Embodiment 2

[0053] When using this patent for semi-automatic height adjustment, when the bridge deck height monitoring system 15 detects that the deviation between the bridge deck height and the reference height reaches the set threshold value, the vertical height adjustment of the support that needs to be set is calculated through the detection data of the bridge deck height monitoring system 15 manually load the power source and control system on the device, start the vertical pushing device 10 through the control system according to the calculated amount, lift the lower seat plate 5 to the preset height by the jack, and complete the vertical height adjustment of the upper structure of the support Adjustment, at this time the inner and outer double helix end surface structure A601 of the lower seat plate 5 is separated from the inner and outer double helix end surface structure B602 double helix structure, and the vertical load of the support is carried by the jack. After the vertical he...

Embodiment 3

[0055] When using this patent for fully automatic height adjustment, when the bridge deck height monitoring system 15 detects that the deviation between the bridge deck height and the reference height reaches the set threshold value, the detection data of the bridge deck height monitoring system 15 is sent to the controller or the self-contained remotely. The control system calculates the vertical adjustment amount of the support to be set, and the control system starts the vertical pushing device 10 in real time according to the obtained data, and lifts the lower seat plate 5 to the preset height by the jack to complete the vertical adjustment of the upper structure of the support. For height adjustment, the inner and outer double helix end surface structure A601 of the lower seat plate 5 is separated from the inner and outer double helix end surface structure B602 double helix structure, and the vertical load of the support is carried by the jack. After the vertical height ad...

Abstract

The invention relates to a stepless height adjusting spherical support. The stepless height adjusting spherical support comprises a support body system, a bridge floor height monitoring system and a height adjusting system, wherein the bridge floor height monitoring system is used for monitoring the height of the bridge floor; the stepless height adjusting spherical support is characterized in that the height adjusting system is arranged below the support body system; the height adjusting system comprises vertical jacking devices, a double-helix contact pair, a horizontal worm wheel and worm transmission mechanism and a bottom seat plate; at least one of the vertical jacking devices, the double-helix contact pair and the horizontal worm wheel and worm transmission mechanism are arranged on the bottom seat plate; at least one of the vertical jacking devices is arranged at the position corresponding to the lower surface of the support body system so as to vertically jack up the support body system during height adjustment; the horizontal worm wheel and worm transmission mechanism can control the double-helix contact pair so as to realize lifting; and the double-helix contact pair has a self-locking function and high vertical bearing stability. According to the stepless height adjusting spherical support provided by the invention, the height of the spherical support can be adjusted according to elevation changes of the bridge floor, the vertical height adjustment can be realized without limitation, and the smoothness of the bridge floor is ensured.

Description

technical field [0001] The invention relates to the technical field of bridges or construction engineering, in particular to a stepless height-adjustable spherical bearing. 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 height adjust...
