Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Shear force is little, the operation space requires drawbacks such as big for solving current hydraulic pressure, the utility model particularly provides a side opening anchor rope hydraulic pressure is cut, the utility model discloses the commonality is high, the shear force is big, light and simple operation. For further explanation of the structure of the present invention, the following detailed description is made with reference to the accompanying drawings:

referring to fig. 1, a hydraulic shear for anchor cable with side opening comprises a tool rest base 1, a stationary knife 2, a movable knife 3 and a hydraulic cylinder.

The tool rest seat is provided with a side slot, and one end of the side slot is used for fixing the static tool. The other end of the side groove is provided with a sliding groove, the movable knife is installed in the sliding groove, the knife rest base is provided with a locking bolt 4 used for fixing the stationary knife through a screw hole, the movable knife is provided with a guide groove, the knife rest base is provided with a guide bolt 5 through a screw hole, and the top end of the guide bolt extends into the guide groove of the movable knife.

The hydraulic oil cylinder is connected with the tool rest base and is arranged close to the movable tool.

The hydraulic oil cylinder comprises a cylinder body 6, a piston 7, a spring and an end cover. The end cover is fixed on the cylinder body and forms a cavity in the cylinder body, the piston is installed in the cavity of the cylinder body, and the cavity in the cylinder body is divided into an oil pressure cavity far away from the movable knife and a spring pressure cavity close to the movable knife by the piston. The spring pressure intracavity is equipped with the suit and is in the spring on the piston, the rear portion of cylinder body be equipped with the communicating adapter 9 in oil pressure chamber. In this embodiment, the adapter is a SHGY3 branch stainless steel through adapter.

The cylinder body is fixedly connected with the knife rest seat, and the piston is fixedly connected with the movable knife.

The hydraulic shear is disassembled and assembled as follows:

the fixed cutter locking bolt is disassembled by using the internal hexagonal wrench, and then the static cutter can be disassembled. The installation sequence is reversed. The guide bolt is unscrewed, the cylinder body is unscrewed, and the movable knife can be taken out along with the piston rod. The installation sequence is reversed. During installation, each workpiece needs to be cleaned, and the matching part is coated with lubricating grease. After the installation is finished, the device walks repeatedly in an idle load way for a plurality of times, and can be used after air in the hydraulic oil way is removed.

The using method comprises the following steps:

1. the appearance of the cutter is checked to see whether each part has abnormal phenomena such as looseness, damage and the like, and the operation can be carried out when all parts are confirmed to be normal.

2. The adapter of the hydraulic shear is connected with the oil pump by a rubber pipe with a quick connector.

3. When the hydraulic shear is operated by one person, and the oil pump is operated by one person to provide pressure oil for the cutter.

4. If the oil pressure cavity of the hydraulic shear is not filled with oil, the piston of the hydraulic shear is firstly made to reciprocate for a plurality of full strokes in an idle load manner. And later, the hydraulic shear can work under load. At this point care should be taken to check whether the two knives are parallel.

5. When the anchor rope was cut off, the part of cutting off will produce the outside and splash, in order to prevent to collapse the splash and hinder and operator, the utility model discloses still install baffle 10 additional.

Referring to fig. 2, the baffle plate comprises a transverse plate 10-1 and side plates 10-2, the side plates are provided with notches, and the side plates are arranged on two side portions of a side groove of the hydraulic shears. The transverse plate is provided with an opening groove, the tool rest base is provided with a bolt penetrating through the opening groove, the bolt is sleeved with a pressure ring 11, and the bolt is sleeved with a pressure spring 12 enabling the pressure ring to compress the transverse plate.

After the anchor cable is positioned between the static cutter and the movable cutter, the baffle plate transversely moves along the notch, and the transverse plate and the side plate of the baffle plate can shield the sheared part of the anchor cable, so that the anchor cable is prevented from being splashed and injured by an operator.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
