Description

Tool for lifting storage tank top from outside in narrow space

Technical Field

The utility model relates to a storage tank deck hoisting device, especially a frock that is used for narrow space to promote storage tank deck from the outside.

Background

With the rapid development of the petrochemical industry, chemical storage and transportation stations are increasing. A large number of liquid chemical storage and transportation stations need to be built in certain coastal areas of China to undertake the transfer work of a large number of liquid chemical raw materials. The gas phase operating pressure at the top of the tank reaches 4000Pa, which is more than 2 times of the conventional design operating pressure 1765Pa of the storage tank. The storage tank is special in storage substance, and all storage tanks and auxiliary facilities thereof all design according to the most harsh medium requirement, and the storage tank is nitrogen gas capping storage tank, and the installation quality requirement of tank deck is higher, need reduce the welding seam as far as possible, reduce tank deck trompil, consequently can not adopt traditional method to promote the storage tank deck from storage tank inside, need adopt several cranes to promote the tank deck from the storage tank outside. But the crane is adopted to lift the tank top, so that the site of a construction site is wide, and the requirement of a crane station can be met. And the crane is adopted to lift the tank top, large-scale equipment needs to be rented, and the cost is high. More serious conditions are that part of construction sites are complicated and narrow, the storage tank foundation is dense, a plurality of cranes cannot simultaneously and reasonably stand, and the tank top cannot be lifted by adopting the cranes, so that a new lifting device needs to be developed to lift the tank top from the outside.

SUMMERY OF THE UTILITY MODEL

The utility model provides a tool for lifting a storage tank top from the outside in a narrow space, which solves the technical problems in the prior art.

The utility model discloses a solve the technical scheme that technical problem that exists among the well-known technique took and be: the utility model provides a frock that is used for narrow space to promote storage tank deck from outside, is two including setting up two stands on outer ring beam basis of jar be equipped with a supporting beam, every between the stand all is equipped with the bearing diagonal, the lower extreme of bearing diagonal and the outer end upper portion rigid coupling of consolidating stable roof beam, consolidate stable roof beam horizontal on outer ring beam basis of jar, set up two placed in the middle between the stand, the outer end is equipped with the landing leg, inner and tank bottoms board rigid coupling the stand bottom is equipped with the base, the base passes through adapting unit and is connected with the outward flange of tank bottoms board the stand top is equipped with rings hang the chain block on the rings.

The reinforcing and stabilizing beam is made of H-shaped steel, and the inner end of the reinforcing and stabilizing beam is fixedly connected with the tank bottom plate through a connecting clamp.

The inclined support is made of angle steel.

The support beam and the upright are made of steel pipes.

The utility model has the advantages and positive effects that: the double-column and the electric chain block are arranged outside the tank top ring wall plate to lift the tank top of the storage tank, so that on one hand, the tank top can be prevented from being perforated, the installation quality of the tank top is ensured, on the other hand, the expense for renting a large crane can be reduced, and the construction cost can be saved. Particularly, the structure that the double-upright-column and the electric chain block are arranged on the outer side of the wall plate of the tank top ring to lift the tank top of the storage tank can be used in a narrow space, and the problem that a large crane in the narrow space is not suitable is solved.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. a support beam; 2. a hoisting ring; 3. chain rewinding; 4. connecting a card; 5. a column; 6. a base; 7. reinforcing the stable beam; 8. a support leg; 9. obliquely supporting; 10. a tank outer ring beam foundation; 11. a tank bottom plate; 12. and a connecting member.

Detailed Description

For further understanding of the contents, features and effects of the present invention, the following embodiments are exemplified in conjunction with the accompanying drawings as follows:

referring to fig. 1, a tool for lifting a tank top of a storage tank from the outside in a narrow space includes two columns 5 arranged on a tank outer ring beam foundation 10, a support beam 1 is arranged between the two columns 5, each column 1 is provided with an inclined support 9, the lower end of each inclined support 9 is fixedly connected with the upper part of the outer end of a reinforcing and stabilizing beam 7, the reinforcing and stabilizing beam 7 is transversely arranged on the tank outer ring beam foundation 10 and is arranged between the two columns 5 in the middle, the outer end of each inclined support is provided with a support leg 8, the inner end of each inclined support is fixedly connected with a tank bottom plate 11, a base 6 is arranged at the bottom of each column 5, so that the stability of the column 5 can be enhanced, and the tank outer ring beam foundation 10 is protected from being. The base 6 is connected to the outer edge of the tank bottom plate 11 by means of a connecting element 12, which prevents the upright 5 from slipping. The top of the upright post 5 is provided with a hanging ring 2, and the hanging ring 2 is provided with a chain block 3.

In this embodiment, the reinforcing and stabilizing beam 7 is made of H-shaped steel, and the inner end of the reinforcing and stabilizing beam 7 is fixedly connected with the tank bottom plate 11 through the connecting clamp 4. The connecting member 12 may be made of angle steel or steel plate strips.

The utility model discloses an use:

calculating the installation number of the tools according to the weight of the lifted tank top, and uniformly distributing all the tools on the basis of the outer ring beam of the tank; and lifting after the installation of the tank top and top ring wall plates of the storage tank is finished, transferring the electric chain block 3 and the stand column 5 into the tank after the installation of the lower ring wall plate is finished after the tank top and top ring wall plates are lifted in place, and performing lifting construction of other wall plates after the installation is finished.
