Abstract
The utility model relates to a hydraulic pull-out device for the basic explosive tube of a mortar shell. The utility model is characterized in that a sleeve barrel is screwed with a cylinder cap of a single-action hydraulic cylinder. Two pulling hooks are hinged with a connecting body, and the two pulling hooks are in spread-out state by two tension springs. The connecting body is screwed with the piston rod of the hydraulic cylinder. When oil is loaded in the hydraulic cylinder, the piston rod shrinks to press a spring in the cylinder and pulls the connecting body and the two pulling hooks into the sleeve barrel. The two pulling hooks shrinks radially simultaneously to clamp the convex edge of the basic explosive tube and pull the basic explosive tube into the sleeve barrel. When the hydraulic cylinder discharges the oil, the piston rod extends and withdraws out of the basic explosive tube under the action of the compression spring in the cylinder. The utility model is hand-held operated, convenient and flexible, and is high in work efficiency.
Description
Technical field
The utility model relates to the basic pencil hydraulic pull-out device of a kind of mortar projectile.
Background technology
Repair the field at ammunition, changing basic pencil is that mortar projectile changes the main contents that part is repaired.At present, the main means with the basic pencil that embeds in the mortar projectile tail pipe is extracted normally adopt the specialized hand spanner to extract, but in conjunction with tighter, then are difficult to extract.
Summary of the invention
In view of this, the long-pending experience of being engaged in this area research work for many years of this creator, through studying repeatedly, proving, shortcoming at above-mentioned prior art existence, create the basic pencil hydraulic pull-out device of a kind of mortar projectile of the utility model, be used to solve basic pencil and extract difficult and inefficient problem.
The technical solution adopted in the utility model is: the basic pencil hydraulic pull-out device of a kind of mortar projectile mainly pulls out hook and forms by compressing spring, sleeve, connector and two in single-action hydraulic cylinder, the cylinder; It is characterized in that: sleeve and hydraulic cylinder cylinder cap are spirally connected, two are pulled out hook and connector is hinged, and making two to pull out hook and be in open configuration with two extension springs, connector and hydraulic cylinder piston rod are spirally connected, during the hydraulic cylinder oil-feed, piston rod shrinks, the compression cylinder inner spring, and pulling connector and two pull out hook and enter sleeve, two are pulled out hook radial contraction simultaneously, block basic pencil convex edge, and pull out in the sleeve; During the hydraulic cylinder oil return, piston rod compresses in cylinder and stretches out under the effect of spring and withdraw from basic pencil.
By the basic pencil hydraulic pull-out device of a kind of mortar projectile of the utility model, overcome the shortcoming of prior art, reached the purpose of above-mentioned creation; The utility model adopts sebific duct to be connected with hydraulic system, and hand held structures is flexible to operation, the operating efficiency height, and the sleeve by the replacing different size with pull out hook,, can carry out extracting of the basic pencil of different-diameter.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As shown in Figure 1, the utility model is by compressing spring 2, sleeve 6, connector 7 in single-action hydraulic cylinder 1, the cylinder and pulling out hook 9 and form; Sleeve 6 is spirally connected with cylinder cap 4, and connector 7 is spirally connected with piston rod 3, and two to pull out hook 9 hinged with connector 7, and make with two extension springs 8 and to pull out hook 9 and be in open configuration, joint 10 is connected with the hydraulic system oil feed line by sebific duct, and button 5 is connected with hydraulic control system by lead, control oil-feed and oil extraction.
The course of work of the present utility model is such: according to the specification of basic pencil, change sleeve 6 and pull out hook 9 before the work; During work, hand-held hydraulic cylinder position, make and pull out hook and aim at basic pencil convex edge, press the button 5, the hydraulic system fuel feeding, piston rod 3 is moved to the left, compression cylinder inner spring 2, drive connector 7 and pull out hook 9 and enter in the sleeve 6, pull out hook 9 radial contraction simultaneously and block basic pencil convex edge, basic pencil is pulled out in the sleeve 6; Release button 5, oil extraction, cylinder inner spring 2 promotes piston rod 2, connectors 7, pull out hook 9 and basic pencil withdraws from sleeve 6, pulls out hook 9 and opens under the effect of extension spring 8 and unclamp basic pencil, finishes a periodic duty process.
In sum, be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
