32 arrive specific bit postpones and is then added between base 11 and tooth bar 32, or, can at base 11 or
Person carries and pre-sets multiple jack on the car body 141 of coaster 14, and when not lifting, jack is non-bulging
In base 11 or car body 141, in order to avoid stopping the mobile route of carrying coaster 14, and arrive at tooth bar 32
Reaching specific bit to postpone, jack rises and protrudes from base 11 or car body to lift tooth bar 32, not with
This is limited.
The tooth bar installation method embodiment of spud leg
One embodiment of the tooth bar installation method of the spud leg that the present invention proposes, wherein this installation method is main
Including: providing a base, longitudinally disposed multiple moulding beds on base, each moulding bed includes positioned opposite
And there is the supporting leg of certain interval, multiple gaps of multiple moulding beds are linked to be a vertical passage；There is provided at least one
Carrying coaster, carrying coaster can move along vertical passage；Spud leg 2 is lifted and is positioned over multiple tire
On frame；Utilize at least one carrying coaster to carry a tooth bar 32, be sent in vertical passage and be positioned
An appointment position below spud leg；Utilize at least one lifting equipment, tooth bar 32 is lifted so that itself and stake
Lower limb contacts and positions；Tooth bar 32 is fixedly welded on spud leg 2.
Specifically, above-mentioned carrying coaster can be selected for the carrying coaster 14 that the present invention proposes, but not with
This is limited.In other embodiments, also may select other structures with replace carrying coaster 14 realize it can
Carry the function of tooth bar 32 movably, and reach on the premise of without repeating to lift spud leg 2, by tooth bar
32 lower sections being delivered to spud leg 2, and it is directly fixed on the purpose of spud leg 2.
It addition, in the present embodiment, the fixed form of tooth bar 32 and spud leg 2 is for being welded and fixed, specifically
For fix for spot welding, but be not limited thereto.Wherein, divide in its both sides owing to spud leg 2 typically requires
Other stationary rack, and in present embodiment while tooth bar 32 is fixedly welded on below spud leg 2, can
By one such as but not limited to the hanging device of door type frame another toothed rack 31 lifted to above spud leg 2 also
It is welded and fixed, using the upper rack as spud leg 2.And by the spud leg tooth bar installation side in present embodiment
The tooth bar 32 that method is fixedly welded on below spud leg is lower tooth bar.The lifting equipment of lifting tooth bar 32 can example
Such as, but not limited to, jack, postpones, by jack when tooth bar 32 is delivered to specific bit by carrying coaster 14
Put in the space between tooth bar 32 and base 11, and utilize jack by fixed to tooth bar 32 jack-up and adjustment
It is positioned at spud leg 2, to guarantee the degree of accuracy being welded and fixed.
In specific implementation process, owing to spud leg 2 is typically to carry out in the way of segmental machining to manufacture,
Independent multistage will be divided into by spud leg 2, individually process each spud leg segmentation, the most again by each spud leg
Segmentation is welded and fixed one overall spud leg of formation together, therefore, in practical operation, tooth bar 31
Installation with tooth bar 32 be also be respectively arranged in each spud leg segmentation with the form of segmentation after, logical
Cross the connection of each spud leg segmentation and combine the complete tooth bar 31 of formation and tooth bar 32.Further, due to tooth bar
For slender member, for avoiding it to send the accidents such as fracture in conveying and installation process, therefore for each
For the tooth bar 31 welded in individual spud leg segmentation and tooth bar 32, it also can install further in segmentation.Such as
Manufacture the spud leg 2 of an a length of 160m, then can manufacture the spud leg segmentation of such as four 40m respectively.?
The tooth bar installation method of the spud leg proposed by the present invention in each spud leg segmentation, is respectively mounted five sections of difference
The tooth bar 32 of the tooth bar 31 and five sections of 8m the longest of long 8m, then to each tooth bar 31 and each tooth bar
The junction of 32 carries out welding processing, or welds a window glass plate further in this junction, not as
Limit.
Though tooth bar installation method and the tooth bar with reference to several spud legs exemplary embodiment describing the present invention
Erecting device, it should be appreciated that term used is that explanation is with illustrative, and not restrictive.Due to
The present invention can be embodied as in a variety of forms without deviating from its design or essence, therefore, above-described embodiment
It is not limited to any aforesaid details, and should in the spirit and scope that appended claims are limited widely
Explain, thus fall in claim or its equivalent scope whole change and remodeling all should be enclose right will
Ask and contained.
