Embodiment

[0041] See Figures 1 to 10 A support for adjusting elevation, this embodiment is applied to the elevation adjustment and self-locking of the bridge support.

[0042] An adjustment element, including upper pedal 1, self-locking regulating mechanism 2, top rising mechanism 3, and next seat 4; the self-locking regulating mechanism 2 and the top rising mechanism 3 are all located in the upper pedestal 1 and said There is between the next platform 4; the bottom portion of the upper pedal 1 is provided with a fixed step portion 1.1, the self-locking regulating mechanism 2 including adjustment rod 2.1 and a movable step ladder 2.2 in conjunction with the fixed step portion 1.1; the active step Block 2.2 slides on the adjustment lever 2.1. When it is necessary to increase the elevation of the upper pedal 1, the top seat 1 is riser to the set position through the top rod 2.1 to adjust the position of the movable step 1.1, the stepped surface and activity step ladder of the fixed step porti...

Abstract

The invention provides a support capable of adjusting the elevation. The support comprises an upper pedestal, a self-locking adjusting mechanism, a jacking mechanism and a lower pedestal; the self-locking adjusting mechanism and the jacking mechanism are both located between the upper pedestal and the lower pedestal; a fixed step part is arranged at the bottom of the upper pedestal, and the self-locking adjusting mechanism comprises an adjusting rod and a movable step block matched with the fixed step part; and the movable step block is arranged on the adjusting rod in a sliding mode. Through the jacking mechanism and the self-locking adjusting mechanism, elevation adjustment and self-locking of the support are achieved, and the overall service life of the support can be prolonged; and self-locking is carried out through the movable step block, relative sliding is not likely to happen between the fixed step part and the movable step block, and the self-locking reliability is high.

Description

Technical field [0001] The present invention relates to the field of bridge holder, and more particularly to a mounting of an elevation. Background technique [0002] High-speed railways are major public infrastructure and lifeline projects related to national security, national economic lifelings and national mensive people's livelihood. At present, my country's high-speed rail operation mileage has exceeded 40,000 kilometers, with the most complex characteristics of long operating mileage, the highest transportation density, and network operation scenarios. The proportion of mileage in high-speed rail bridges is very high, with an average of more than 50%, up to 94.2%. [0003] As the operation time increases, the high-speed rail bridge is gradually appeared in the co-action of complex multi-source loads such as trains and temperature. Including the cumulative deformation and subsidence of the high-speed rail bridge Due; the adjacent bridge high difference is hinged to produce ...
