Problems solved by technology
However, when this method is used for the installation of the overall cold box, there are two major problems: first, the size of the large-scale air separation overall skid-mounted cold box is large, and the specifications and heights of the anchor bolts are not the same, and the bolts are not circular. Square and other standard shapes, coupled with the large volume of the cold box foundation, and long construction time, if the traditional formwork fixing bolt method is used, it will have a great impact on the cost, construction period, etc., and the foundation pouring and maintenance process will also Risk of uncontrollable deformation
Second, after the overall cold box is enlarged, the thickness of the bottom plate of the cold box and the specifications of the anchor bolts are doubled. Whether it is reaming the bottom plate or adjusting the bolts, it will take a long time, which not only increases the risk of hoisting the cold box , it is also possible to delay the hoisting of the cold box until night

Embodiment Construction
[0025] The present invention is further illustrated below by specific examples.
[0026] Such as Figure 1~Figure 6 As shown, a combined overall cold box foundation bolt positioning measurement mold includes a combined support beam, a leveling top tool and a positioning template; wherein the combined support beam includes a plurality of support beam modules connected to each other through flanges 1. The support beam module 1 is a box-shaped structure. After the combination of the combined support beam is completed, it is used to record the relative positional relationship between the anchor bolt groups of each column foot of the cold box and serve as a fixed positioning template for the support structure; The transverse width of the support beam is determined according to the size of the floor beam of the cold box; the support beam modules 1 are connected through flange surfaces 3, and public ribs 5 are respectively arranged on the flange surfaces 3 of each adjacent support be...

Specifically, the present invention is a combined overall cold box foundation bolt positioning measurement mold; it is characterized in that it includes a combined support beam, a leveling top tool and a positioning template; wherein the combined support beam includes a support beam module; the leveling top tool is used for Support the entire combined support beam, and adjust the flatness of the support beam; the positioning template is a steel plate, which is used to record the positional relationship of each column bolt, and the positioning template is set on the combined support according to the screw hole position of the cold box on the beam. This measurement mold can accurately feed back the pre-embedded position of the foundation bolts of the cold box to the assembly workshop without being affected by factors such as operators and weather. The influence of the arrangement shape of the foot bolts, the difference in bolt specifications, and the difference in bolt elevation.
Description
technical field [0001] The invention relates to the field of equipment maintenance, in particular to a combined integral cold box foundation bolt positioning and measuring mold and a method for using the same. Background technique [0002] The large overall skid-mounted cold box is super-long and overweight equipment. After the overall assembly is completed in the assembly workshop, it is transported to the site, and the whole is hoisted and fixed on the pre-embedded anchor bolts of the cold box foundation. Since the thickness of the bolt backing plate of the overall cold box bottom plate and the foundation bolts of the cold box both reach 10cm, once the bolt positioning deviation occurs, it will greatly increase the difficulty of handling the cold box backing plate, and at the same time increase the hoisting time and hoisting risk. Referring to the traditional construction experience of other large-scale equipment, steel plates and section steel are usually used to make sha...
