Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of industrial module equipment, and more particularly to a large module hoisting system. BACKGROUND

[0002] With the promotion of chemical plant modularization, the size and weight of the module are increasing, and the installation of the module is also challenged.

[0003] According to the current construction experience, the module installation methods are roughly divided into two kinds, one is to use SPMT hydraulic axis vehicle to transport to the installation position, and to be lifted into place. This method has certain requirements for the construction site and the installation position. One is to use hoisting machinery to hoist into place, and this form is more widely applicable.

[0004] At present, the vertical butt joint precision of large modules in the industry is difficult to control within a small range. The main reason is that the weight of the temporary reinforcement structure, paint, fire retardant paint and the like during the manufacturing process of the large module cannot be accurately estimated. There is a deviation between the actual center of gravity and the theoretically calculated center of gravity, and the length of the hoisting rigging cannot be accurately calculated. Whether the module is lifted into place by transportation or large machinery, the center of gravity of the module is the key.

[0005] For the hoisting into place which is more widely applicable, the greater the deviation between the center of gravity of the module and the geometric center of the module after the module is lifted, the greater the horizontal difference of each column. The conventional hoisting rigging cannot meet the installation precision requirements and needs to be adjusted repeatedly. CONTENT OF THE UTILITY MODEL

[0006] In order to solve the above problems, the present application provides a large module hoisting system.

[0009] Further, the lifting assembly comprises a lifting hook and a ring-shaped lifting cable, the ring-shaped lifting cable is in the shape of a pyramid as a whole, the top end of the ring-shaped lifting cable is connected to the lifting hook, and the bottom section of the ring-shaped lifting cable is connected to the first balance beam.

[0010] Further, the first balance beam is a square frame arranged horizontally, and the top and bottom of the four corners are fixedly connected with first shackles.

[0011] Further, the second balance beam is a square frame arranged horizontally, and the bottom of the four corners and the center of the long side of the second balance beam are provided with second shackles, and the top of the vertical sling is connected with the second shackle.

[0012] Further, the long side size of the first balance beam is the same as the short side size of the second balance beam, and the vertical projection size of the second balance beam is approximately the same as the hoisted large module.

[0013] Further, the synchronous lifting control assembly comprises a SyncHoist hydraulic balance device and a controller, two ends of the SyncHoist hydraulic balance device are connected with the first shackle and the main sling respectively, and the controller is arranged at the center of the first balance beam.

[0023] Example 1:

[0024] The present application will be further described in detail below with reference to the accompanying drawings.

[0025] This application discloses a large module hoisting system, including a hoisting assembly 1. A first balance beam 2 is provided at the bottom of the hoisting assembly 1. A main sling 3 is provided at the bottom of the first balance beam 2. A synchronous lifting control assembly 4 is provided at each connection point between the main sling 3 and the first balance beam 2. A second balance beam 5 is provided at the bottom of the synchronous lifting control assembly 4. Six vertical slings 6 are connected to the bottom of each of the second balance beams 5. Turnbuckles 7 are fixedly connected to the bottom of each of the vertical slings 6. The bottom of the turnbuckles 7 is connected to the large module being hoisted.

[0026] As a further preferred embodiment, the lifting device assembly 1 includes a hook 11 and an annular sling 12. The annular sling 12 is generally pyramid-shaped, with its top end connected to the hook 11 and its bottom end connected to the first balance beam 2.

[0027] As a further preferred embodiment, the first balance beam 2 is a horizontally arranged square frame, with first shackles 21 fixedly connected to the top and bottom of its four corners. The annular sling 12 and the synchronous lifting control assembly are both connected to the first shackles 21.

[0028] As a further preferred embodiment, the second balance beam 5 is a horizontally arranged square frame, and the bottom four corners and the center of the long side of the second balance beam 5 are provided with second shackles 51, and the top of the vertical sling 6 is connected to the second shackles 51.

[0029] As a further preferred embodiment of the present application, the long side dimension of the first balance beam 2 is the same as the short side dimension of the second balance beam 5, and the vertical projection dimension of the second balance beam 5 is approximate to the large module being hoisted.

[0030] As a further preferred embodiment of the present application, the synchronous hoisting control assembly 4 comprises a SyncHoist hydraulic balance device and a controller, two ends of the SyncHoist hydraulic balance device are connected with the first shackle 21 and the main sling 3 respectively, and the controller is arranged at the center position of the first balance beam 2.

[0031] The implementation principle of the large module hoisting system according to the embodiment of the present application is as follows: due to the integrity of module manufacturing, the center of gravity of the module is generally measured after the manufacturing is completed. At that time, the center of gravity cannot be changed, and the rigging can only be adjusted according to the actual center of gravity. Because the modules are manufactured in batches, the adaptability of the hoisting rigging is a big challenge. It is necessary to not only meet the force of multiple lifting points, but also ensure the levelness and perpendicularity of the module. As shown in the figure, the actual center of gravity of the module deviates from the geometric center by 753 mm in the length direction and by 211 mm in the width direction. After the module is lifted, the plumb line of the hook passes through the actual center of gravity, and the module as a whole is inclined. In view of the different direction deviations of multiple modules, the stroke of the hydraulic balance system is selected as the maximum value of 1200 mm according to the maximum rigging adjustment, and the rated lifting capacity of the hydraulic balance system is selected according to the maximum force of 130 tons. The SARS PIN precise positioning system is comprehensively selected and used, the maximum tension of a single oil cylinder is 200 tons, the full extension length is 4455 mm, the full retraction length is 2955 mm, and the stroke is 1500 mm. Adjustment is made at the positions of the four main slings, and the Hub adjustment system is placed at the position of the top balance beam. The effectiveness of the adjustment is ensured, and the number of SyncHoist Units used is reduced. At the same time, the system has the following advantages: the system is powered by electricity, the main power supply is 380V, and the auxiliary power supply is 220V, both of which are domestic industrial power supply and household power supply. The adjustment accuracy can reach 1mm, which meets the adjustment of the levelness and perpendicularity of the module, saves the installation time, and saves the customer 0.5-1 day in installation and docking. The operation is flexible, the four SyncHoist Units can be used vertically or obliquely, individually or simultaneously, manually or automatically, and individually or simultaneously. Wireless Wifi control can be performed, and the effective distance is 200m. At the same time, real-time visibility is provided, that is, through the interface of the remote controller, the cylinder stroke size, lifting height and load size of each SyncHoist Unit can be seen.

[0032] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
