Abstract
The utility model discloses an accidental fall-off preventing structure of a hammer rod sealing sleeve of a high-pressure oil cylinder. The accidental fall-off preventing structure comprises a high-pressure oil cylinder, wherein the hammer rod sealing sleeve I of the high-pressure oil cylinder is installed outwards along a hammer rod from the inside of the cylinder. A boss is arranged at one end of the sealing sleeve I and is connected with a boss arranged at an end cover of the high-pressure oil cylinder in a matching manner, and the sealing sleeve I is provided with a screw thread and is connected with the end cover of the high-pressure oil cylinder in a matching manner. A sealing sleeve II which is installed inwards along the hammer rod from the outside of the cylinder is also arranged at the hammer rod of the high-pressure oil cylinder. The accidental fall-off preventing structure has the benefits of convenience for maintenance, simple structure, simplicity of implementation and low cost, can effectively increase the safety factor, and fundamentally guarantees the personal safety of staff.
Description
Technical field
The utility model relates to a kind of anti-accidental structure, and especially a kind of high-voltage oil cylinder hammer stem stuffing box gland is prevented the accidental structure.
Background technique
Current, in process industry, 5 tons of electric liquid hammers that are provided with, because that equipment uses is frequent, poorly sealed phenomenon appears in stuffing box gland wherein easily, light then phenomenon that high pressure oil occurs overflowing, heavy then stuffing box gland comes off, and high pressure oil will leak in a large number; This leakage often all is in the equipment generation that just is being in operation; The high temperature of 5 tons of electric liquid hammer hammerings is beaten workpiece this moment also on anvil; When the workpiece of high temperature meets the oil of leakage,, cause just workman's personal injury of operation below equipment easily with causing very fierce burning.Even even more serious consequence.
The model utility content
The purpose of the utility model is for overcoming the deficiency of above-mentioned existing technology, provide high-voltage oil cylinder hammer stem stuffing box gland to prevent the accidental structure, and it has practical, the good characteristics of producing effects.
For realizing above-mentioned purpose, the utility model adopts following technical proposals:
A kind of high-voltage oil cylinder hammer stem stuffing box gland is prevented the accidental structure, and it comprises high-voltage oil cylinder, and said high-voltage oil cylinder hammer stem stuffing box gland I installation direction is by outside along hammer stem in the cylinder.
Said stuffing box gland I one end is provided with boss, and is connected with boss that the high-voltage oil cylinder end cap is provided with.
Said stuffing box gland I is provided with screw thread and is connected with the high-voltage oil cylinder end cap.
Said high-voltage oil cylinder hammer stem also is provided with installation direction by the inside stuffing box gland II of cylinder outer hammer stem.
Through implementing, because stuffing box gland and high-voltage oil cylinder end are connected.The boss that is provided with forms good screens; The high pressure oil applied pressure acts on the stuffing box gland, can only make stuffing box gland lean against the high-voltage oil cylinder end more closely, and stuffing box gland keeps original position under the effect of oil pressure; With the mounting type that relies on screw thread and high-voltage oil cylinder to be connected merely before; Safety factor is strengthened greatly, when stuffing box gland II under the high pressure oil effect during accidental, stuffing box gland I guarantees that high pressure oil can not leak suddenly in a large number.Solved unexpected a large amount of leakage of high pressure oil, to below staff's work threat.
The utility model beneficial effect is:
1. easy to maintenance, can effectively improve safety factor;
2. simple in structure, be prone to implement, cost is low.
3. fundamentally ensured staff's personal safety.
Description of drawings
Fig. 1 is the structural principle of the utility model;
1. high-voltage oil cylinder, 2. hammer stem, 3. stuffing box gland I, 4. stuffing box gland II.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
A kind of high-voltage oil cylinder hammer stem stuffing box gland is prevented the accidental structure, and it comprises high-voltage oil cylinder 1, and the hammer stem stuffing box gland I3 installation direction of said high-voltage oil cylinder is by outside along hammer stem 2 in the cylinder.
Said stuffing box gland I3 one end is provided with boss, and is connected with high-voltage oil cylinder 1 end.
Said stuffing box gland I3 one end is provided with screw thread and is connected with the high-voltage oil cylinder end cap.
Said high-voltage oil cylinder hammer stem also is provided with installation direction by the inside stuffing box gland II4 of cylinder outer hammer stem 2.
Though the above-mentioned accompanying drawing that combines is described the embodiment of the utility model; But be not restriction to the utility model protection domain; One of ordinary skill in the art should be understood that; On the basis of the technological scheme of the utility model, those skilled in the art need not pay various modifications that creative work can make or distortion still in the protection domain of the utility model.
