Abstract
The utility model relates to a hydraulic cutter used for cutting steel strands, which is particularly suitable for underground tunnel supporting and protection sites of coal mine which use steel strand anchor cables. In order to overcome the defects of short service life of the cutter, difficult repair and no protection measures of the single-edge form of the existing hydraulic cutter, the utility model is provided with double edges, a fixing edge and a moving edge which have the same cylindrical hole-shaped structure; the utility model can be used in a rotation of any angle mode or in a reverse rotation of 180 DEG. When the utility model is operated, the double edges mutually move in an overlapped movement mode, and meanwhile, the steel strands are cut; cylindrical inner holes of the double edges simultaneously have the action of clamping and holding to the steel strands to enable cutting to save labor. The utility model is provided with a semi-closed cylindrical protection cover, cutting liquid can be increased to prevent spark when cutting, and meanwhile, the steel strands can be prevented from skipping to hurt people. The utility model has the advantages of simple structure and operation, labor saving, high safety, high strength of the cutter, long service life, convenient manufacture, maintenance and operation.
Description
Affiliated technical field
The utility model relates to a kind of hydraulic pressure that is used for steel strand wires to be cut, and especially is fit to the scene of the used steel strand wires anchor cable of roadway support under the coal mine.
Background technology
At present, the hydraulic pressure shearing in the time must cutting steel strand wires anchor cable exposed parts, because of using flame cutting or toothless saw cutting, can only be used in the scene of China's used steel strand wires anchor cable of roadway support under the scene, particularly coal mine of using steel strand wires.At present, the hydraulic pressure that is used for steel strand wires is cut seldom, and existing hydraulic pressure is cut and is yi word pattern single-blade degree of lip-rounding formula, its complex structure, and volume is big, and the cutter working life is short and heavy, repairs very difficultly, wastes a large amount of cutter materials; And unshielded measure, it is dangerous to work.
Summary of the invention
In order to overcome the above-mentioned defective that existing hydraulic pressure is cut, the purpose of this utility model is to provide a kind of hydraulic pressure that is used for steel strand wires to cut, has double blade, fixed blade and mobile cutlery have same cylinder hole shape structure, rotatable arbitrarily angled or reverse 180 ° and use, cutting edge is through specially treated, the cutting edge strength height, life-span is long, and is easy to processing and reparation; Be provided with semitight tubular protective cover, can add cutting fluid during shearing and prevent to produce spark, prevent to cut off steel strand wires simultaneously and jump out and hurt sb.'s feelings.
The technical scheme that its technical problem that solves the utility model adopts: have double blade, fixed blade has the cylinder barrel shaped overall structure, and cylinder barrel shaped two ends shape is identical, cutting edge is 90 ° and R1 rounding, the intensity height, rotatable arbitrarily angled maybe can the counter-rotating 180 ° used, and has the cylindrical hole cutting edge form the same with fixed blade on the mobile sword, the 180 ° of uses of can reversing.On the fixed cutter body that the fixed blade interference fits is set in hydraulic cylinder is connected, mobile sword is connected by pin with the piston knife bar, is provided with return spring between hydraulic cylinder and piston knife bar; During work, the mutual changing of the relative positions of mobile sword and fixed blade, double blade is sheared steel strand wires simultaneously, and the cylinder barrel shaped structure of mobile sword and fixed blade has clamping action simultaneously to steel strand wires, makes shearing more laborsaving.
Be provided with semitight tubular protective cover, can add cutting fluid (water etc.) during shearing, eliminate the moment spark that produces when cutting off, use safer in the down-hole; The steel strand wires of cutting are poured out by the detachable tubular protective cover of sealing, can not collapse to hurt sb.'s feelings, and are safe.
The beneficial effects of the utility model are: cutter intensity height, and the life-span is long, making, maintenance, easy to use; Simple in structure, in light weight, simple, labor-saving and safe.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.

In Fig. 1,1, transit joint, 2, hydraulic cylinder, 3, sealing ring, 4, the piston knife bar, 5, return spring, 6, hold-down screw, 7, mobile sword, 8, fixed blade, 9, fixed cutter body, 10, sealing gasket, 11, screw, 12, pressing plate, 13, holding screw, 15, sealing ring, 16, sealing is stifled, and 17, protection cylinder, 19, sealing gasket
The specific embodiment
In Fig. 1, fixed blade (8) is set in the fixed cutter body (9), and fixed blade and fixed cutter body are that interference fits is inlayed, and is detachable; Fixed cutter body (9) is threaded with hydraulic cylinder (2); Mobile sword (7) is connected by hold-down screw (6) with piston knife bar (4), between hydraulic cylinder (2) and piston knife bar (4) return spring (5) is arranged.Protection cylinder (17) is connected on the fixed cutter body (9) by holding screw (13), sealing gasket (19), and the protection cylinder front end is provided with sealing stifled (16), sealing ring (15); Sealing gasket (10), pressing plate (12) are fixed in the cutter hub front end with screw (11) forms semiclosed shearing chamber.
When using this device, add entry or other cutting fluid, steel strand wires are inserted in mobile sword and the fixed blade circular hole in the shearing chamber; Hydraulic oil is entered in the hydraulic cylinder (2) by transit joint, promoting piston knife bar (4) and mobile sword (7) moves, this moment mobile sword and mutual changing of the relative positions of fixed blade, double blade is sheared steel strand wires simultaneously, and the cylinder barrel shaped structure of mobile sword and fixed blade has clamping action simultaneously to steel strand wires, makes shearing more laborsaving.When steel strand wires are cut off, the hydraulic cylinder unloading, the piston knife bar is being with mobile sword to get back to the home position under the effect of return spring.The steel strand wires of cutting are poured out by the detachable tubular protective cover of sealing, can not collapse to hurt sb.'s feelings, and are safe.
In embodiment illustrated in fig. 2, fixed blade adopts the cylinder barrel shaped overall structure, and cutting edge is 90 ° and R1 rounding, the intensity height; Rotatable arbitrarily angled use; Cylinder barrel shaped two ends shape is identical, the 180 ° of uses of can reversing; Endoporus φ A makes the different size size according to the different size steel strand wires, in shear history steel strand wires is had clamping action; Excircle dimension φ B is identical, can be set in in a kind of cutter hub, has enlarged the scope of application that hydraulic pressure is cut.
In the embodiment shown in fig. 3, have the cylindrical hole cutting edge form the same with fixed blade on the mobile sword, cutting edge is 90 ° and R1 rounding, the intensity height; Endoporus φ A makes the different size size according to the different size steel strand wires, and the two sides structure is identical, the 180 ° of uses of can reversing.
