Abstract
The utility model relates to a special tool for disassembling a sealing gland. The special tool comprises a fixed plate, a main threaded rod, a drive nut, a thrust bearing and a bearing chamber, wherein the fixed plate is provided with a plurality of fixing holes, the main threaded rod is screwed from the center of the fixed plate, the thrust bearing sleeves the main threaded rod and is fixedly connected with the fixed plate through the bearing chamber, and the drive nut sleeves the main threaded rod and is disposed above the thrust bearing. The sealing gland is uniformly pulled out along the central line by a pulling forced applied to the thrust bearing and a rotating force applied to the thread, thereby realizing the aim of not damaging parts of equipment; the special tool is safe, reliable, and simple to operate, and helps to save labor and time for disassembling maintenance and raise the working efficiency; and the size of the special tool can be adjusted at will so as to adapt to sealing glands of different types, and thus the special tool is strong in applicability and generalization performance.
Description
Technical field
The utility model belongs to Petro-Chemical Machinery field, relates to the maintenance tool of a kind of watt of Shandong sealing gland, particularly a kind of sealing gland tool special for dismounting.
Background technology
At present, various sealing glands are widely used in the middle of the plant equipment of the industries such as chemical industry, textile machine, food processing, oil, especially those inflammable, explosive, poisonous mediums, on the relatively high equipment of pressure, often use sealing gland, conventionally the cylinder body that sealing gland matches with it adopts minimum matched in clearance, to apply auxiliary seal ring etc. simultaneously, after completing, assembling can well guarantee assembly quality and effect, but often there is the problem such as not quick detachable after application a period of time, give the follow-up maintenance degree of adding to the difficulties.For this reason, there is technical staff to keep in repair and often adopt hammering method, although the method dismounting easily, due to shock loading, easily cause sealing gland and miscellaneous part impaired; Also the technical staff who has time adopts percussion hammer method in maintenance, but this method has its limitation, and when equipment does not discharge while building the pressure completely, dismounting jumps out gland very easily suddenly, may cause casualties.Based on the problems referred to above, can sealing gland for convenience detach if can design one, can also reduce the damaged condition to equipment component simultaneously, there is again the instrument of security reliability, will extremely be conducive to the development of industry.
Summary of the invention
The purpose of this utility model is to provide a kind of sealing gland tool special for dismounting, and the sealing gland that solves current pressure vessel is not quick detachable, and danger coefficient is large in the process of dismounting, and easily equipment component is caused the problem of damage.
The utility model is achieved through the following technical solutions: sealing gland tool special for dismounting, comprise fixed head, driving screw, drive nut, thrust bearing and bearing chamber, wherein, on fixed head, have multiple fixing holes, driving screw screws in from fixed head central authorities, thrust bearing is enclosed within on driving screw and is affixed by bearing chamber and fixed head, and drive nut is enclosed within on driving screw and is positioned at thrust bearing top.
Described fixed head front end is also with protective cover.
On described protective cover, have arc observation panel.
Adopt the good effect of technique scheme:
1, the utility model acts on pulling force on thrust bearing, utilizes the revolving force of screw thread that sealing gland is evenly pulled out along center line simultaneously, has realized the not object of damage equipment parts;
2, on the utility model front end is provided with protective cover, fixed head, safe fixing hole can effectively prevent the unsafe factor that builds the pressure and cause in equipment, dismantlement work safety and reliability;
3, when the utility model uses, simple to operate, save the time of manpower and laid-up, improve operating efficiency;
4, arbitrarily adjustment means size of the utility model, to adapt to various forms of sealing glands, applicability generalization is strong.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is installment state structural representation before the utility model dismounting;
Fig. 3 is installment state structural representation after the utility model dismounting.
In figure, 1 fixed head, 2 driving screws, 3 drive nuts, 4 thrust bearings, 5 bearing chambers, 6 fixing holes, 7 protective covers, 8 arc observation panels.
The specific embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but should not be construed as restriction of the present utility model:
Fig. 1 is structural representation of the present utility model, as shown in the figure, sealing gland tool special for dismounting, comprise fixed head 1, driving screw 2, drive nut 3, thrust bearing 4 and bearing chamber 5, wherein, on fixed head 1, have multiple fixing holes 6, for fixed head is connected with equipment outer cylinder body, play the effect of fixing fixed head 1.Driving screw 2 screws in from fixed head 1 central authorities, thrust bearing 4 is enclosed within on driving screw 2 also affixed by bearing chamber 5 and fixed head 1, drive nut 3 is enclosed within on driving screw 2 and is positioned at thrust bearing 4 tops, and thrust bearing 4 has reduced the frictional force between drive nut and fixed head, makes rapid operation.
Because equipment cylinder interior has certain pressure, certain potential safety hazard that built the pressure within when dismounting, in order to guarantee safety, described fixed head 1 front end is also with protective cover 7.
On described protective cover 7, have arc observation panel 8, easily install and be convenient to and observe.
Fig. 2 is installment state structural representation before the utility model dismounting, Fig. 3 is installment state structural representation after the utility model dismounting, shown in Fig. 2, Fig. 3, this device in use, first observe the size of dismounting gland internal thread, select suitable driving screw, fixed head is placed on sealing gland, utilize fixing hole to tight a bolt fixed head is fixed on equipment outer cylinder body, on the arc observation panel observation of protective cover driving screw being threaded with the sealing gland utilization that needs dismounting.Now, by regulating drive nut, under the effect of rotation pulling force, sealing gland can be pulled out from equipment cylinder body.Finally, as long as again set bolt is backed out, pull down this device entirety, get final product end operation.
Operation principle of the present utility model is exactly that pulling force is acted on the thrust bearing that bears specially axial force, utilize the revolving force of screw thread that sealing gland is evenly pulled out along center line simultaneously, simple to operate laborsaving when use, and realized the not object of damage equipment parts, overcome the drawback of existing method for dismounting; In addition, the fixing hole on protective cover, fixed head that the utility model front end is provided with, can effectively prevent from the unsafe factor that builds the pressure and cause in equipment from making device use safety and reliability.
