Description

Packing lifting tool for ultrahigh-pressure compressor

Technical Field

A packing lifting tool of an ultrahigh pressure compressor belongs to the field of packing lifting equipment.

Background

In the chemical industry, the running pressure of the reciprocating type ultra-high pressure compressor can reach more than 260MPa, and the high-pressure packing is used as a key sealing component for running the reciprocating type ultra-high pressure compressor, so that the installation quality and the maintenance efficiency of the reciprocating type ultra-high pressure compressor have important influences on the normal running of equipment and the normal production and operation of devices.

The high-pressure packing consists of a cylindrical packing barrel with the length of 1m and packing sheets inside, and the mass of the high-pressure packing is more than 200 kg. In the current maintenance process, the high-pressure packing is installed by using a crane and a hanging belt, fixing two ends of the packing, and hoisting and installing the packing at a designated position of a compressor cylinder. The method has certain disadvantages, firstly, the quality and the diameter of the filler are large, the horizontal posture of the filler for hoisting is not easy to find by adopting a hanging belt binding and fixing mode, the filler is easy to slide down, and potential safety hazards exist.

The Chinese patent application with the patent name of 202021951013.4 discloses a technical scheme, in which a mounting frame is arranged, and when loading is carried out, the packing is sleeved on a hack lever in the mounting frame, and then the packing is completed by a hoisting frame fixed with the mounting frame. However, the following drawbacks still exist in this technical solution: (1) In this technical solution, since the packing is sleeved in the mounting frame, it is known from common knowledge in the art that this technical solution is only suitable for packing with a smaller weight, and since the packing cannot be fixed, there is still a certain safety hazard. (2) In actual operation, the packing acts as a sealing member, an oil film exists between the packing and the mounting surface of the compressor cylinder,

because the clearance between the cylinder and the filler is smaller, the oil film can cause larger viscous force between the cylinder and the filler in the process of loading and unloading the filler with the cylinder, so that the loading and unloading of the filler are difficult in actual operation sites, and the technical scheme does not consider the problem of difficult disassembly caused by the oil film, in particular the problem of disassembly of the filler. (3) Since the filler has a certain weight, the center of gravity of the charging tool is changed between a state where the filler is mounted and a state where the filler is not mounted, and the larger the weight of the filler is, the more remarkable the situation is, and the problem of coaxiality of the filler and the compressor cylinder caused by the change of the center of gravity of the tool is not considered in the technical scheme.

As shown in fig. 1 to 3, an ultrahigh pressure compressor packing lifting tool (hereinafter referred to as lifting tool) comprises a lifting framework, wherein the lifting framework comprises a top beam 5 horizontally arranged, a first lifting ring 3 and a second lifting ring 8 are arranged at two ends of the top beam 5 side by side, and one side of the second lifting ring 8 is defined as the front end of the lifting tool in the lifting tool.

A vertical beam 6 is vertically fixed at the rear end of the top beam 5, a rear beam 2 is horizontally fixed at the lower part of the rear side of the vertical beam 6, a handle 1 is horizontally fixed at the rear end of the rear beam 2, the handle 1 is vertical to the top beam 5, the vertical beam 6 and the rear beam 2, and the top beam 5, the vertical beam 6 and the rear beam 2 are integrally arranged.

A circular mounting tray 7 is arranged below the front end surface of the vertical beam 6, and the circle center of the mounting tray 7 is arranged opposite to the rear beam 2. A plurality of mounting holes 9 which penetrate axially are uniformly formed in the outer periphery of the mounting tray 7. The bottom of the vertical beam 6 is also provided with a charging auxiliary hole 10, the charging auxiliary hole 10 is positioned below the mounting tray 7, and the charging auxiliary hole 10 is a smooth hole axially formed along the mounting tray 7. And a discharging auxiliary nut 4 is also fixed on one side above the vertical beam 6, the discharging auxiliary nut 4 is positioned above the mounting tray 7, and the axis of the threaded hole of the discharging auxiliary nut is parallel and coplanar with the axis of the mounting tray 7.

The specific working process and working principle are as follows:

when the filler 12 is filled, as shown in fig. 4-5, the travelling crane hook is connected with the first hanging ring 3, and at this moment, the first hanging ring 3 is positioned on the gravity center line of the hanging tool when the hanging tool is in no-load, so that the hanging tool can be kept in a balanced posture in the air. Then the hoisting tool is moved to the filler 12, bolts on the end face of the filler 12 penetrate through the mounting holes 9 of the outer ring of the mounting tray 7 in a one-to-one correspondence manner, and the filler 12 and the mounting tray 7 are fixed through nuts.

At this time, the lifting tool is fixed with the filler 12, so that the gravity center is changed, and the travelling crane hook is transferred onto the second lifting ring 8 from the first lifting ring 3, and at this time, the second lifting ring 8 is positioned on the gravity center line of the lifting tool and the filler 12, so that the lifting tool and the filler 12 can be kept in a balanced posture in the air. And finally, hoisting the hoisting tool and the filler 12 to a charging position at the port of the cylinder 13 by using a crane, and charging the filler 12 into the cylinder 13 from the charging position of the cylinder 13.

Since an oil film exists between the inner wall of the cylinder 13 and the outer wall of the packing 12, the viscous force at the time of loading is large, and thus the loading process tends to be difficult, at this time, the auxiliary bolt 11 is set, the auxiliary bolt 11 is previously loaded into the threaded hole of the end face of the cylinder 13, and the auxiliary bolt 11 is loaded into the end of the threaded hole.

When the packing 12 is in butt joint with the cylinder 13, the auxiliary bolt 11 firstly passes through the loading auxiliary hole 10 at the bottom of the vertical beam 6, and a nut is arranged at the rear end of the auxiliary bolt 11, and when the cylinder 13 is in butt joint with the packing 12, the packing 12 and the cylinder 13 are gradually close by rotating the nut at the rear end of the auxiliary bolt 11 and pulling force of the auxiliary bolt 11 until the packing 12 is completely loaded into the cylinder 13.

And finally, removing nuts for fixing the filler 12 and the mounting tray 7, transferring the crane hook from the second lifting ring 8 to the first lifting ring 3, and removing the lifting tool by using a crane to finish filling of the filler 12.

When the filler 12 is dismounted, as shown in fig. 6-7, the travelling crane hook is connected with the first hanging ring 3, at this moment, the first hanging ring 3 is positioned on the gravity center line of the lifting tool when the lifting tool is in no-load, the lifting tool can be kept in the balance attitude in the air, the lifting tool is moved to the filler 12 position at the port of the air cylinder 13 through the travelling crane, bolts on the end face of the filler 12 penetrate through the mounting holes 9 of the outer ring of the mounting tray 7 in a one-to-one correspondence manner, and the filler 12 is fixed with the mounting tray 7 through nuts. And then the travelling crane hook is replaced to the second lifting ring 8 from the first lifting ring 3, and at the moment, the second lifting ring 8 is positioned on the gravity center line of the lifting tool and the filler 12, so that the balance gesture of the lifting tool and the filler 12 in the air can be maintained.

Since an oil film exists between the inner wall of the cylinder 13 and the outer wall of the packing 12, viscous force at the time of loading is large, so that the difficulty of the disassembly process is often large, the auxiliary bolt 11 is set at this time, the auxiliary bolt 11 is loaded into the unloading auxiliary nut 4, and the auxiliary bolt 11 is gradually brought into contact with the port of the cylinder 13 as the auxiliary bolt 11 is rotated. Along with the continuous rotation of the auxiliary bolt 11, the auxiliary bolt 11 continuously pushes the air cylinder 13 to be far away from the filler 12, and finally the filler 12 is ejected out of the air cylinder 13, in the process, the lifting tool is pulled outwards by manpower in combination with the handle 1, and the disassembly of the filler 12 is assisted.

The above description is only a preferred embodiment of the present utility model, and is not intended to limit the utility model in any way, and any person skilled in the art may make modifications or alterations to the disclosed technical content to the equivalent embodiments. However, any simple modification, equivalent variation and variation of the above embodiments according to the technical substance of the present utility model still fall within the protection scope of the technical solution of the present utility model.
