Abstract

The invention relates to an overturning process of heavy equipment. The overturning process adopts the following overturning steps of: A, connecting a supporting rod to an overturning crane; B, connecting a plurality of groups of pulleys to the supporting rod; C, respectively connecting two ends of a wire rope to two hanging lugs on the heavy equipment; D, connecting a hook of another overturning crane to the hanging lugs of the heavy equipment; E, simultaneously hoisting the heavy equipment and simultaneously raising the heavy equipment to set height by the two overturning cranes; F, gradually hoisting the heavy equipment and overturning the transverse heavy equipment to be vertical by one overturning crane while the other overturning crane is immobile; and G, firstly dismounting the hook, connected with the heavy equipment, of one overturning crane to erect the heavy equipment on the ground, and then dismounting the hook, connected with the heavy equipment, of the other overturning crane, thus completing the overturning process of the heavy equipment. Due to the overturning process, the requirement on design strength of the hanging lugs of the heavy equipment can be lowered, the production cost can be saved, and the working efficiency and the overturning stability of the heavy equipment can be improved.

Description

The upset technology of heavy wares

Technical field

The present invention relates to heavy wares, relate in particular to a kind of upset technology of heavy wares.Belong to the steel structure construction applications.

Background technology

In steel structure is built engineering, a lot of as: heavy waress such as tower crane class need be transported to the strange land and install.It is in shipment, and heavy wares not only needs horizontal placement, and, before lifting, after also needing it is carried out tipped upright, be placed on the place of erection again.In the process that it is stood up, because the part hanger of heavy wares, it is far longer than its holding capacity when upright lifting in horizontal holding capacity.This just needs to calculate earlier heavy wares in switching process, and how many maximum, force that its hanger that is used for the lifting upset can bear is, then, again according to its stressing conditions, is used for upset at the large-scale hanger of equipment design.But, because the hanger design is excessive, not only can destroy heavy wares body coating, and, because the part outer wall of heavy wares is thinner, thereby, cause welding the large-scale hanger for upset; Therefore, need the additional designs temporary frame work, in order to auxiliary upset.Thus, not only expended a large amount of human and material resources, and, be easy to generate bigger rocking in the switching process, cause the instability of upset.

Summary of the invention

Main purpose of the present invention is to overcome the above-mentioned shortcoming that prior art exists, and provide a kind of upset technology of improved heavy wares, it not only can reduce heavy wares Lug Design requirement of strength, has reduced because the welding hanger is measured the destruction of heavy apparatus body coating; And also the use amount of minimizing upset subframe has been saved productive costs, has improved work efficiency; Simultaneously, improved the stability of heavy wares upset effectively.

The objective of the invention is to be realized by following technical scheme:

A kind of upset technology of heavy wares is characterized in that: adopt following overturning step:

The first step is connected strut with a upset loop wheel machine;

In second step, the array pulley is connected on the strut;

In the 3rd step, the two ends of steel rope are connected respectively on two hangers that are located on the heavy wares by shackle;

In the 4th step, another drop hanger that overturns loop wheel machine is connected on the hanger of heavy wares;

In the 5th step, control two upset loop wheel machines and lift by crane simultaneously, and heavy wares is lifted a setting height simultaneously;

The 6th the step, one the upset loop wheel machine motionless, another the upset loop wheel machine promote heavy wares gradually, with heavy wares by laterally turning to vertical direction;

The 7th step shed the drop hanger that a upset loop wheel machine is connected with heavy wares earlier, with the upright placement of heavy wares on the ground, shed the drop hanger that another upset loop wheel machine is connected with heavy wares again, had just finished the switching process of heavy wares.

The setting of described array pulley is: being installed on the pulley with steel cable is one group, and according to the heavy wares size array is set.

Beneficial effect of the present invention: the present invention is owing to adopt technique scheme, and it not only can reduce heavy wares Lug Design requirement of strength, has reduced because the welding hanger is measured the destruction of heavy apparatus body coating; And also the use amount of minimizing upset subframe has been saved productive costs, has improved work efficiency; Simultaneously, improved the stability of heavy wares upset effectively.

The specific embodiment

The present invention adopts following overturning step:

The first step as shown in Figure 1, uses shackle 4 with steel rope 3 strut 1 to be connected with a upset loop wheel machine 2; That is: in project implementing process, strut 1 is connected all by shackle 4 and steel rope 3 with loop wheel machine 2, carry hanger on the strut 1, link together by the eye splice of shackle 4 with the hanger on the strut 1 and steel rope 3, then, the eye splice of steel rope 3 other ends directly is connected with the suspension hook of the loop wheel machine 2 that overturns gets final product again.

In second step, as shown in Figure 2, adopt the mode of twining to be installed on the pulley 5 steel cable 3; Being installed on the pulley 5 with steel cable 3 is one group, and according to the heavy wares size array can be set; As shown in Figure 3, array pulley 5 is connected on the strut 1, present embodiment is two groups.

In the 3rd step, as shown in Figure 4, the two ends of steel rope 3 are connected respectively on two hangers 7 that are located on the heavy wares 6 by shackle 4;

In the 4th step, as shown in Figure 5, another drop hanger that overturns loop wheel machine 8 is connected on the hanger 9 of heavy wares 6;

In the 5th step, as shown in Figure 6, control two upset loop wheel machines (2,8) and lift by crane simultaneously, and heavy wares 6 is lifted a setting height simultaneously;

The 6th the step, as shown in Figure 7, the upset loop wheel machine 8 motionless, the upset loop wheel machine 2 promote heavy wares 6 gradually, with heavy wares 6 by laterally turning to vertical direction;

The 7th step as shown in Figure 8, shed the drop hanger that upset loop wheel machine 8 is connected with heavy wares 6 earlier, and heavy wares 6 uprightly is placed on the ground 10, shed the drop hanger that upset loop wheel machine 2 is connected with heavy wares 6 again, had just finished the switching process of heavy wares 6.

Above-mentioned upset loop wheel machine, strut, steel rope, pulley, shackle, hanger are prior art, and the technology that does not explain is prior art.

The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
