Detailed Description

The present invention will now be described in detail with reference to the accompanying drawings and examples.

Example 1

The utility model provides a jar body is pulled out a mouthful correction frock of subsiding includes support frame 1, correction piece 2, portal frame 3 and jack.

In the embodiment, referring to fig. 1, two support frames 1 are provided, and the support frame 1 is integrally i-shaped; the support frame 1 comprises a support seat 12 and a support surface 11 arranged on the support seat 12; the supporting seat 12 and the supporting surface 11 are fixed through a plurality of fixing rods, the supporting surface 11 is arc-shaped, the radian of the arc is matched with that of the outer surface of the tank body, the two axial ends of the tank body are arranged on the supporting surface 1, and the arc-shaped supporting surface is matched with the tank body to prevent the tank body from sliding under stress in the correcting process.

In this embodiment, referring to fig. 2, the correcting block 2 includes a base 22 and a bearing block 21 disposed on the base 22; the number of the bases 22 is two, the number of the bearing blocks 21 is one, the bearing blocks 21 are rectangular cylinders, the bearing blocks 21 are arranged above the central points of the connecting lines of the two bases 22, and two ends of the upper surface of each bearing block 21 are respectively fixed with the two bases 22; two ends of the lower surface of the bearing block 21 are respectively fixed with the two bases 22; so that the whole structure of the correcting block is in an isosceles triangle structure. Specifically, base 22 is the rectangle steel sheet, and the lower surface be arc and radian and treat the radian looks adaptation of correcting jar internal surface, like this, when the lower surface of base and the surface of the department of collapsing contact, the arc contact is fully laminated, when pushing down jar body department of collapsing under the jack effect simultaneously, the internal surface of jar body also is the arc, and consequently the mouth that pulls out after the correction error of collapsing is little, and the transition is pleasing to the eye.

In this embodiment, referring to fig. 3, the tank opening drawing and collapse correcting tool further includes a portal frame 3, and the jack is arranged on the portal frame 3.

Referring to fig. 3, in the present embodiment, the gantry 3 includes a fixing plate 31 and a frame body 32 disposed on the fixing plate 31, and the frame body 32 has a door-shaped overall structure and is composed of a cross bar and two vertical bars; the two vertical rods are fixed on the fixing plate 31, the jack is fixed on the cross rod and can move freely along the transverse direction of the cross rod, and the jack is enabled to apply pressure on the supporting surface 11.

When the jack is implemented, the jack is an electric jack and is formed by combining a hydraulic cylinder and an electric pump station, and the operation in various forms such as jacking, pushing, pulling, extruding and the like can be realized.

Example 2

Taking a specific application of the pull-out collapse correction as an example, a correction method of the pull-out collapse is explained.

The diameter of the existing tank body is 0.7m, the axial length of the tank body is 2 m, 3 pulling openings are formed in different positions on the side wall of the tank body, and the pulling openings are collapsed.

The conventional collapse is continuously corrected by knocking by a manual machine, so that the error is large, the construction quantity is large, and the efficiency is low.

The utility model discloses a jar body that embodiment 1 provided is pulled out the mouth and is subsided correction frock and is proofreaied and correct above-mentioned jar body subsides. The specific correction method comprises the following steps:

1) placing the two support frames at proper positions on a portal frame fixing plate, arranging two axial ends of the tank body on the support frames and contacting with support surfaces of the support frames, and placing two vertical rods of the portal frame at two radial sides of the tank body so that the jack is placed above the tank body;

2) rotating the tank body according to the position of the pull opening on the tank body to be corrected, wherein the collapse position faces downwards;

3) the straightening block is placed into the tank body from one end of the tank body, the base of the straightening block is in contact with the collapse position, and the jack is aligned with the pressure-bearing block through other pulling openings on the top of the tank body, which are closest to the collapse position, so that the jack can downwards penetrate through the other pulling openings on the tank body to be in contact with the pressure-bearing block;

4) the jack acts on the pressure-bearing block downwards through other pull openings on the tank body, so that the correcting block is continuously stressed downwards under the action of the jack, the collapse part in contact with the correcting block base is also stressed downwards, and finally the collapse part in the tank body is corrected under the action of the jack.

When other collapse positions need to be corrected, the correcting block is moved or the tank body is rotated, so that the collapse positions face downwards, meanwhile, the jack is aligned with the bearing block through other drawing openings, which are closest to the collapse positions, in the top of the tank body, stress points are guaranteed, and the jack is prevented from being emptied; then, the collapse parts are all corrected by adopting the method.

Example 3

Different from the embodiment 1 and the embodiment 2, when the tank body is long, three support frames 1 can be adopted, when the tank body is used, the support frames 1 are arranged on the fixing plate 31 of the portal frame 3 in the same direction and are arranged on the same horizontal line, the tank body is axially arranged on the support surfaces 11 of the three support frames 1, the two axial ends of the tank body are arranged on the support frames 1, the middle part of the tank body is arranged on one support frame 1, and the tank body is ensured not to roll under the stress of three points.
