Description
Technical field
The present invention relates to gantry design fields, specifically, more particularly to a kind of suitable for girder and end carriage use
The adjustment device of the loading bridge of horizontal flange pattern connection.
Background technique
Currently, the loading bridge of the horizontal flange linked vector graph of domestic production, generally according to traditional process group
Dress, i.e. girder are fixed after mixing up, and high-altitude adjusts the scheme of end carriage, as shown in Figure 1.Such method has following features:
1, head room has been raised by the way that tiltedly slightly transition connects end carriage in girder both ends, makes the vertical end carriage of group must high altitude operation.
Task difficulty is big, and safety coefficient is low.
2, the three big parameters that need to be adjusted when girder is fixed, diagonal line, span, levelness are both needed to through large-scale ancillary equipment such as
The cooperations such as gantry crane or truck crane are completed, and pilot process also needs that block is welded and fixed, and applies the tools such as jack.Workload is big, effect
Rate is low.
3, six big parameters of high-altitude adjustment end carriage, levelness, difference of height, diagonal line, span, are also needed with potential difference verticality
It is completed, and six big parameters influence each other, and need to adjust repeatedly, personnel's skilled operation degree is required high by large-scale ancillary equipment.
4, particularly with the end carriage that minor diameter wheel is housed, standard-required level and Vertical Parameters error range are small, to survey
Measuring appratus required precision is high, proposes higher technical requirements to survey crew.
Therefore, research and develop it is a kind of in terrestrial operation and be able to achieve quickly assembling and each parameter can standard compliant device become
Technical problem urgently to be resolved.
Summary of the invention
End carriage is adjusted according to high-altitude set forth above, task difficulty is big, the low technical problem of safety coefficient, and provides a kind of fast
The device and its application method of speed assembling horizontal flange pattern gantry.The present invention is mainly machined with using supporting leg top for horizontal
The cross slotted hole of beam connection, lower part are equipped with lower margin by double nut, so that supporting leg is adjusted in vertical direction and go up and down；Bolt
