Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1-6, the present invention provides an embodiment: the utility model provides a special frock for large-scale chemical industry equipment swift current tail drag row, includes connecting plate 1 and backup pad 2, is provided with a plurality of fixed through-hole 3 on the connecting plate 1, and backup pad 2 vertical fixation is in the connecting plate 1 side, and 2 lateral parts of backup pad are provided with the arcwall face.

In this embodiment, if the typical pressure vessel main equipment of gasifier class is difficult for setting up swift current tail lug, this frock is to the hoist and mount that is applicable to the equipment of treating 4 tail band flanges of hoist and mount equipment or skirt. Each part of this frock can adopt welding mode to connect fixedly, when guaranteeing bulk strength, convenient processing preparation. The connecting plate 1 is of a plate structure, and corresponding fixing through holes 3 are arranged according to the positions of bolt holes of a flange at the tail part of the equipment to be hoisted or a skirt. The cambered surface of backup pad 2 can guarantee to be in good contact with swift current tail drag line 6 at the hoist and mount in-process to conduct the holding power to treating 4 afterbody of lifting device through connecting plate 1, increased through this frock and treated 4 afterbody of lifting device's swift current tail lifting surface area, thereby reduced and treated 4 impaired risks of lifting device deformation. In order to prevent the equipment to be hoisted 4 from rolling in the hoisting process, a sleeper 5 can be additionally arranged between the arc-shaped surface of the supporting plate 2 of the tool and the tail dragging row 6, so that the risk of relative displacement between the tool and the tail dragging row 6 is reduced.

When hoist and mount, rise slowly along with main part of hanging, swift current tail drag row 6 also slowly follows the removal, and when rising to wait lifting device 4 and ground contained angle increase, the arcwall face of backup pad 2 follows the roll on swift current tail drag row 6, can guarantee that the atress direction is transmitted perpendicularly to waiting to lifting device 4 afterbody. After the equipment 4 to be hoisted is lifted to the vertical state, the tool can be disassembled to carry out subsequent installation operation.

The utility model discloses a change and treat 4 afterbody atress modes of lifting device and with the 6 contact modes of row of dragging of swift current tail, with the flange or the skirt of afterbody atress dispersion to the afterbody, with stability and the security that promotes the swift current tail in-process, will treat 4 afterbody tradition of lifting device 4 afterbody simultaneously and slide the radial atress of tail in-process and become the plane atress, avoided treating the deformation damage risk that lifting device 4 leads to because of local atress is concentrated, this frock processing preparation is simple and convenient economy, the operation process is simple rapid stabilization, safety and reliability, but the safety of maximum assurance hoist and mount.

In the preferred embodiment, the steel plate support further comprises reinforcing rib plates 7, and the reinforcing rib plates 7 are vertically connected with the connecting plate 1 and the support plate 2. In order to strengthen the rigidity of the whole structure, the integral strength in the using process can be improved by adding the reinforcing rib plate 7, so that the reliability and the safety of the tool are further improved.

In the preferred embodiment, the number of the reinforcing rib plates 7 is four, and the four reinforcing rib plates 7 are respectively and symmetrically arranged at two sides of the connecting plate 1. Four deep floor 7 symmetrical arrangement can further promote the reliability when guaranteeing intensity.

In a preferred embodiment, the arc-shaped surface of the supporting plate 2 is provided with anti-skid projections. The anti-slip bulge of the arc-shaped surface of the supporting plate 2 can increase the friction force between the anti-slip bulge and the tail-sliding towing row 6, so that the risk of relative displacement is further reduced.

In a preferred embodiment, the surfaces of the connecting plate 1 and the supporting plate 2 are provided with antirust coatings. The service life of the tool can be further prolonged through the antirust coating, so that the cost is reduced.

With the above embodiment, taking the hoisting of a certain heavy device 4 to be hoisted in the frame as an example, the practical new specific use process comprises the following steps:

s1, firstly, connecting and fixing the equipment 4 to be hoisted with the tool; the mounting center of the equipment 4 to be hoisted in the frame is 24m away from the outer frame of the frame, the main lifting lug of the equipment 4 to be hoisted adopts a pair of shaft type lifting lugs, and the top of a circular end socket at the tail part of the equipment 4 to be hoisted is provided with a DN800 flange. The matched tool is designed and processed according to the arrangement condition of the flange bolt holes and the diameter of the tail part of the equipment to be hoisted 4, after the tool is manufactured, the tool is fixed on the flange at the tail part by using the stud matched with the flange at the tail part of the equipment to be hoisted 4, and meanwhile, the arc-shaped surface of the supporting plate 2 is parallel to the axes of the two main lifting lugs.

S2, connecting the tool with a tail dragging row 6; put tail-sliding towing raft 6 well in advance, lay several layers of sleepers 5 on it, increase the frictional force between tail-sliding towing raft 6 and this frock, prevent to produce relative displacement between the two at tail-sliding in-process. The equipment 4 to be hoisted is placed on the tail sliding towing line 6 through the tool.

And S3, finally completing equipment hoisting operation. After the steps are ready, the main crane is slowly lifted, the tail sliding towing line 6 slowly slides and follows, and the main crane and the tail sliding need to be kept consistent so as to realize stable lifting of the equipment. Along with equipment rises to rise, this frock rolls on sleeper 5, can guarantee that equipment afterbody atress is even, and the completion is hoisted the operation this time until equipment is in vertical state.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
