Abstract
The utility model discloses a large-bore vertical column of a structure free of a local weld joint. The large-bore vertical column comprises an outer cylinder of the vertical column, a first clamp, a second clamp and a third clamp are fixed to the outer wall of the outer cylinder, and a protective cover assembly, a valve plate and a hanging ring are fixed to the first clamp, the second clamp and the third clamp respectively. Due to the fact that the protective cover assembly, the valve plate, the hanging ring and the like are respectively fixed to the outer circle of the outer cylinder through bolts, and the position of a lower cavity of the outer cylinder under high pressure acting force is not provided with the weld joint, the influence of the weld joint on base metal of the outer cylinder is avoided, and the service life of the vertical column is prolonged.
Description
Technical field
The utility model relates to a kind of hydraulic support column, relates in particular to a kind of large cylinder diameter column without local welding line structure.
Background technology
At present, the hydraulic support producer that many collieries are used is all in the application life of make great efforts improving column, and the factor that affects column application life mainly contain following some:
1, can the intensity of column own meet instructions for use, and 2, the project organization of column, 3, the machining accuracy of each major part, 4, the quality of seal, 5, whether operating mode severe etc.
As shown in Figure 1, suspension ring, valve plate, guard shield etc. are all soldered on outer shell outer wall pillar construction of the prior art.
At least there is following shortcoming in above-mentioned prior art:
No matter be when support model machine intensity test, while still using in down-hole, all occurred the phenomenon of column outer shell explosion.
Utility model content
The purpose of this utility model is to provide a kind ofly can avoid the explosion of column outer shell, improve the column large cylinder diameter column without local welding line structure in application life.
The purpose of this utility model is achieved through the following technical solutions:
Large cylinder diameter column without local welding line structure of the present utility model, the outer shell that comprises column, on the outer wall of described outer shell, be fixed with the first clip, the second clip, the 3rd clip, on described the first clip, the second clip, the 3rd clip, be fixed with respectively cover assembly, valve plate, suspension ring.
The technical scheme being provided by above-mentioned the utility model can be found out, the large cylinder diameter column without local welding line structure that the utility model embodiment provides, due to by guard shield, valve plate, suspension ring etc. all with clip form with being bolted on outer shell cylindrical, outer shell cavity of resorption is subject to the position no-welding-seam of High Pressure power, therefore the impact of weld seam on outer shell mother metal, the application life of having improved column have been avoided.
Accompanying drawing explanation
Fig. 1 is the structural representation of large cylinder diameter column of the prior art;
The structural representation of the large cylinder diameter column without local welding line structure that Fig. 2 provides for the utility model embodiment.
In figure: 1, outer shell, 2, guard shield, 3, valve plate, 4, suspension ring, 5, cover assembly, the 6, first clip, the 7, second clip, the 8, the 3rd clip, 9, bolt.
The specific embodiment
To be described in further detail the utility model embodiment below.
Large cylinder diameter column without local welding line structure of the present utility model, its preferably the specific embodiment be:
The outer shell that comprises column, is fixed with the first clip, the second clip, the 3rd clip on the outer wall of described outer shell, on described the first clip, the second clip, the 3rd clip, be fixed with respectively cover assembly, valve plate, suspension ring.
Described cover assembly comprises guard shield seat, and described guard shield seat is provided with screw, and with bolt, by described guard shield seat and described the first clamp connection, described bolt is simultaneously by the outer wall of the fixing described outer shell of described the first clip.
Described valve plate side is provided with screw, and with bolt, by described valve plate and described the second clamp connection, described bolt is simultaneously by the outer wall of the fixing described outer shell of described the second clip.
Described suspension ring and described the 3rd clip weld together, and with bolt, described the 3rd clip are fixed on the outer wall of described outer shell.
Applicant analyzes producing the possibility of this phenomenon of column outer shell explosion in prior art, mainly contain 2 points: the one, itself there is defect in raw material, next is that the weld seam of other part that welds on outer shell outer wall has caused that the tissue of earthen pipe mother metal part changes, and has accelerated the fatigue failure of outer shell.
The utility model improves from the structure of simple in structure, economic and practical angle column, by guard shield, valve plate, suspension ring etc. all with clip form with being bolted on outer shell cylindrical, outer shell cavity of resorption is subject to the position no-welding-seam of High Pressure power, therefore the impact of weld seam on outer shell mother metal, the application life of having improved column have been avoided.
Specific embodiment, as shown in Figure 2:
By guard design, be assembly, on guard shield seat, have screw, with bolt, by the clamp connection of itself and outer shell outside, be fixed on outer shell cylindrical, protection feed tube;
Valve plate lateral layout has screw, with bolt, by the clamp connection of itself and outer shell outside, is fixed on outer shell cylindrical;
Suspension ring and clip weld together, and are fixed by bolts on outer shell cylindrical.
Column of the present utility model, has avoided local welding on the outer cylinder body outer wall impact on maternal tissue, has effectively guaranteed the mechanical performance that possesses after outer cylinder heat treatment to have played conclusive effect the application life of column to improving.
The above; it is only the preferably specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
