Embodiment 1

[0019] Such as figure 1 Shown: The flange connection equipment is a new vertical heat exchanger, which includes two parts, the shell side and the tube box. The tube box is on the top, and the shell side is on the bottom. Two bushings 3 are installed, and the two bushings 3 are respectively welded on the shell side cylinder through the connecting plate 1. The lower bushing 3 is provided with a lock nut 2, and the horizontal part of the boom 4 is provided with a vertical Worm screw screw lifter 5, suspension hook 6 is installed in its lifting screw mandrel lower end.

[0020] The new vertical heat exchanger of this embodiment is disassembled and then reassembled for on-site inspection and maintenance as follows:

[0021] Disassembly and assembly of the upper pipe box

[0022] ① Weld the connecting plate 1 to the shell side of the heat exchanger, and connect the hook 6 and the flange (or lifting lug) with a wire rope.

[0023] ②Remove the bolts connecting the pipe box flange a...

Embodiment 2

[0028] The flange connection equipment is an old vertical heat exchanger, and its shell-side cylinder is allowed to be welded. Others are the same as in Embodiment 1.

[0029] The on-site maintenance of this embodiment is completely the same as that of Embodiment 1 when it is first dismantled and then reassembled.

Embodiment 3

[0031] The flange connection equipment is an old vertical heat exchanger, and its shell-side cylinder is not allowed to be welded. Others are the same as in Embodiment 1.

[0032] In this embodiment, when on-site maintenance is first dismantled and then reassembled, if figure 2 As shown, first a clamp 7 is prefabricated and the clamp 7 is fastened on the shell side cylinder, and then the connecting plate 1 is welded to the clamp 7, and the rest is completely the same as that of the first embodiment.

Abstract

The invention particularly relates to a simple and convenient vertical bent arm flange connection equipment dismounting and mounting device. The dismounting and mounting device is characterized in that the dismounting and mounting device comprises a lifting arm, a shaft sleeve, a connecting plate, a lifting hook and a lifting hook lifting device; the lifting arm is of an inverted-L-shaped bent structure; the lower portion of a vertical part of the lifting arm is sleeved with at least one shaft sleeve; the connecting plate is arranged on the inner side of the shaft sleeve; and the lifting hooklifting device and the lifting hook are arranged on a transverse part of the lifting arm. The dismounting and mounting device has the advantages of being simple in structure, low in cost, flexible andconvenient to use and high in efficiency. By using the dismounting and mounting device, hoisting equipment does not need to be used, and the dismounting and mounting cost is greatly lowered; and thedismounting and mounting device is small in size, and is slightly limited by the height and space of roads and devices, dismounting and mounting on the device site are quite convenient, and the dismounting and mounting efficiency can be greatly improved.

Description

technical field [0001] The invention specifically relates to a simple and convenient disassembly device for vertical curved arm flange connection equipment. Background technique [0002] In industrial production, there are many devices that can be disassembled through flange connections. During the assembly or disassembly of the two parts to be connected, lifting equipment (driving, truck crane, back chain, etc.) is required. Especially during the maintenance of the device, due to the limitation of the road, the height of the device, the space, etc., it is extremely troublesome to disassemble and assemble at the device site. Contents of the invention [0003] The purpose of the present invention is to solve the defects of high cost, time-consuming, laborious and inconvenient disassembly and assembly that need to use lifting equipment when disassembling and assembling the current flange connection equipment, and provide a simple and convenient disassembly of the vertical c...
