Background
At present, fractionating tower cold box board hoist and mount lug is before the hoist and mount of cold box steel sheet, adopts the gas cutting to cut the hole in cold box board skeleton hoisting point position, passes through the hole with the lug and is connected with the shackle, need increase a great steel sheet in order to increase the contact surface between lug connecting plate and cold box skeleton simultaneously to reduce the local atress of cutting position, hoist and mount at every turn and all need dismantle the rigging, and increased first section material and cut with the gas material input. In addition, adopt the gas cutting to cut the cold box skeleton, destroyed the integrality of skeleton itself and damaged the paint on steel construction surface, and need drop into gas cutting instrument and professional constructor and carry out the gas welding cutting operation during cold box skeleton prefabrication.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model and the technical task who provides are perfect and improve prior art scheme, provide fractionating tower cold box board hoist and mount lug assembly to simplify lug installation operation, reduce construction cost for the purpose. Therefore, the utility model adopts the following technical scheme.
Fractionating tower cold box board hoist and mount lug subassembly, including lug, lug connecting plate, bolt, nut, the lug connect and be fixed in on the lug connecting plate, the lug connecting plate on be equipped with a plurality of bolted connection holes, bolted connection hole position corresponds with the mounting bolt hole position on the cold box skeleton of cold box board, the bolt pass the mounting bolt hole of cold box board and the bolted connection hole of lug connecting plate, fasten through the nut. Lug fixed mounting is realized to the mode of fixing through the bolt to the lug connecting plate, bolt hole when can make full use of fractionating tower cold box board installation, avoided cutting the trompil on the cold box skeleton, the integrality of protection steel construction that can be fine only needs to use monkey wrench or box spanner, does not need the cooperation of professional gas cutting constructor, just can accomplish the installation of lug, does not need repeated dismantlement rigging during hoist and mount many times, and convenient operation can also used repeatedly, effectively reduces construction cost.
As a further improvement and supplement to the above technical solution, the present invention further comprises the following additional technical features.
As a preferable technical means: and flat washers are respectively arranged on the lower side of the mounting bolt hole and the upper side of the bolt connecting hole on the bolt. Through setting up the plain washer, can increase the bearing area at bolt-up position, dispersion pressure prevents to cause the damage to the junction.
As a preferable technical means: the nut adopts double nuts. The double-nut structure can effectively prevent looseness.
As a preferable technical means: and reinforcing rib plates are symmetrically arranged between the lifting lugs and the lifting lug connecting plate. The structural strength can be effectively increased, and the bearing capacity of the lifting lug assembly is improved.
As a preferable technical means: the lifting lugs and the lifting lug connecting plates are connected in a welding mode, and the reinforcing rib plates are connected with the lifting lugs and the lifting lug connecting plates in a welding mode. Adopt welding mode to connect, the wholeness is good, and structural strength is high, simple structure.
Has the advantages that: lug fixed mounting is realized to the mode of fixing through the bolt to the lug connecting plate, bolt hole when can make full use of fractionating tower cold box board installation, avoided cutting the trompil on the cold box skeleton, the integrality of protection steel construction that can be fine only needs to use monkey wrench or box spanner, does not need the cooperation of professional gas cutting constructor, just can accomplish the installation of lug, does not need repeated dismantlement rigging during hoist and mount many times, and convenient operation can also used repeatedly, effectively reduces construction cost.
