Description

Technical Field

[0001] The utility model belongs to the technical field of single hydraulic prop pressing, and in particular relates to a single hydraulic prop pressing device for a mine. Background Art

[0002] Single hydraulic props are widely used in coal mines and other mining industries. Single hydraulic props are a kind of supporting equipment composed of cylinders, pistons, valves and other parts. The three-way valve is its core component, which is responsible for fluid supply, unloading and ensuring constant resistance characteristics. The working principle of single hydraulic props involves the column raising and initial support stages, in which the column raising is achieved by operating the injection gun handle to allow high-pressure liquid to enter the lower cavity of the prop, and the piston rises until the piston no longer rises. The injection gun cuts off the pressure and the column raising process is completed. In the process of suppressing the single hydraulic prop, the existing suppressing auxiliary devices do not have the effect of fixing the single hydraulic prop. Occasionally, the stamping port will have poor contact and pressure leakage during the suppressing process of the single hydraulic prop, which will cause the single hydraulic prop to fall sideways due to impact. Therefore, a new type of single hydraulic prop suppressing device is needed to enhance safety. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a single hydraulic prop pressure device for a mine, thereby solving the problems in the above-mentioned background technology.

[0004] The purpose of the utility model is achieved as follows: a single hydraulic support suppressing device for a mine, comprising a chassis, a moving component is arranged at the bottom of the chassis, a left support plate and a right support plate are fixedly connected to the peripheral side wall of the chassis, the plate surfaces of the left support plate and the right support plate are both provided with locking components, a plurality of hexagonal columns are arranged on the upper surface of the chassis, and the plurality of hexagonal columns are vertically extended with equal spacing between adjacent hexagonal columns, the upper ends of the plurality of hexagonal columns are fixedly connected by a top ring, and the interior of the top ring is provided with reinforcing ribs; a docking groove is arranged on the upper surface of the chassis and between adjacent hexagonal columns, and the docking groove is arranged corresponding to the top ring, an upper threaded hole and a lower threaded hole are opened on the side wall of the hexagonal column, the interior of the upper threaded hole and the lower threaded hole are both threadedly connected with a top pressure column, and the interior of the top pressure column is provided with a rectangular through hole. When in use, the lower end of the single hydraulic prop is inserted into the docking groove to pressurize the inside of the oil cylinder. As the inside of the oil cylinder continues to be pressurized, the inner tube of the oil cylinder extends upward, and the upper end of the inner tube presses against the bottom surface of the top ring. By setting a top pressure column on the hexagonal prism, after the lower end of the single hydraulic prop is inserted into the docking groove, the top pressure columns on the hexagonal prisms on both sides of the single hydraulic prop are rotated, so that the top pressure columns clamp and fix the single hydraulic prop from both sides, making the single hydraulic prop more stable during the process of pressing the oil cylinder, and the single hydraulic prop will not fall sideways even if the pressure leaks at the punching port, which greatly improves safety.

[0005] Further, the locking assembly includes a left locking member and a right locking member, the left locking member includes a left threaded hole provided on the surface of the left support plate, the left screw is connected to the inner thread of the left threaded hole, a left driving portion is fixedly provided on the upper end of the left screw, and the left driving portion is in the shape of a hexagonal prism. The right locking member includes a right threaded hole provided on the surface of the right support plate, the right screw is connected to the inner thread of the right threaded hole, a right driving portion is fixedly provided on the upper end of the right screw, and the right driving portion is in the shape of a hexagonal prism. When in use, the left screw is driven to rotate by the left driving portion, and the right screw is driven to rotate by the right driving portion. During the rotation of the left and right screws, the left and right screws will move upward or downward. When the left and right screws move downward, their lower ends contact and squeeze the ground, and the friction between the left and right screws and the ground is utilized to achieve a locking effect, thereby preventing the chassis from moving unexpectedly.

[0006] Furthermore, a support plate is fixedly provided at the lower end of the left screw and the right screw, and a plurality of anti-skid convex strips are fixedly provided on the lower surface of the support plate, and the anti-skid convex strips are used to further increase the friction force. By setting the support plate, the contact area between the left screw and the right screw and the ground is increased, thereby increasing the friction force.

[0007] Furthermore, the moving assembly includes a first base, a second base, a third base and a fourth base fixedly arranged on the lower surface of the chassis, and the lower ends of the first base, the second base, the third base and the fourth base are all provided with rotating wheels. When in use, the left screw and the right screw are moved upward, and the lower ends thereof are separated from the ground, and the chassis is conveniently moved by the setting of the rotating wheels.

[0008] Furthermore, a hand pull ring is fixedly provided above the right supporting plate and on the side wall of the hexagonal prism; the left supporting plate, the right supporting plate and the base are integrally formed.

[0009] The beneficial effects of the utility model are as follows: the lower end of the single hydraulic prop is inserted into the docking groove to pressurize the inside of the oil cylinder. As the inside of the oil cylinder continues to be pressurized, the inner tube of the oil cylinder extends upward, and the upper end of the inner tube presses against the bottom surface of the top ring. By arranging a top pressure column on the hexagonal prism, after the lower end of the single hydraulic prop is inserted into the docking groove, the top pressure columns on the hexagonal prisms on both sides of the single hydraulic prop are rotated, so that the top pressure columns clamp and fix the single hydraulic prop from both sides, making the single hydraulic prop more stable during the oil cylinder pressurization process, and the single hydraulic prop will not fall sideways even if the pressure leaks from the punching port, which greatly improves safety.

[0010] The left drive unit drives the left screw to rotate, and the right drive unit drives the right screw to rotate. The left and right screws move upward or downward during rotation. When the left and right screws move downward, their lower ends contact and squeeze the ground. The friction between the left and right screws and the ground is used to achieve a locking effect to prevent the chassis from moving unexpectedly. The support plate is set to increase the contact area between the left and right screws and the ground, thereby increasing the friction. The left and right screws are moved upward, and their lower ends are separated from the ground. The rotating wheel is set to facilitate the movement of the chassis. BRIEF DESCRIPTION OF THE DRAWINGS
