Problems solved by technology

[0002] The lifting structure is one of the commonly used mechanical structures in mining machinery. At present, the screw rod placed in the cylinder is driven by a servo motor to rotate, so that the ball nut pair on the screw rod converts the rotational motion of the screw rod into a linear motion and drives the inner cylinder in the The cylinder moves inside, so that the length formed by the inner cylinder and the cylinder body becomes longer or shorter, achieving self-locking while lifting, but the weight of the inner cylinder and the weight of the components connected to the inner cylinder directly act on the output of the servo motor end, it is easy to cause damage to the servo motor and affect the service life of the servo motor

specific Embodiment approach

[0040] The specific embodiment: the bolts for fixing the connecting plate 9 are installed at the desired position through the through hole 8, and the fixing of the position of the connecting plate 9 is completed, that is, the position of the cylinder body 1 is limited, and the inner cylinder 6 and the inner cylinder 6 are connected by the connecting plate 4. The components that need to be driven are connected, and the servo motor 13 is controlled by PLC to rotate forward or reversely, and then the ball nut pair 17 converts the rotary motion of the screw rod 15 into a linear motion and drives the inner cylinder 6 to move in the cylinder body 1, thereby realizing lifting At the same time, the ball nut pair 17 drives the slider 24 to slide along the chute 16. During the sliding process, the slider 24 scrapes off the dust attached to the inner surface of the chute 16 into the groove 25, and then falls into the groove 25. The dust inside slides down the inclined surface of the inner...

Abstract

The invention relates to the technical field of mining machinery, in particular to a self-locking device for a lifting structure of mining machinery, including a cylinder body, a blind plate, an inner cylinder, a servo motor, a screw rod, a ball nut pair, a slider, and a chute And the pressure transfer component, when using the servo motor to drive the screw to rotate, the ball nut pair converts the rotary motion of the screw into a linear motion and drives the inner cylinder to move in the cylinder, so as to achieve the purpose of lifting. The pressure transfer component transfers the weight of the inner cylinder and the weight of the parts connected to the inner cylinder to the blind plate through the pressure transfer component, preventing the pressure from directly acting on the servo motor to achieve the purpose of pressure transfer and preventing the servo motor from being damaged due to pressure. damaged.

Description

technical field [0001] The invention relates to a self-locking device for a lifting structure of mining machinery, which belongs to the technical field of mining machinery. Background technique [0002] The lifting structure is one of the commonly used mechanical structures in mining machinery. At present, the screw rod placed in the cylinder is driven by a servo motor to rotate, so that the ball nut pair on the screw rod converts the rotational motion of the screw rod into a linear motion and drives the inner cylinder in the The cylinder moves inside, so that the length formed by the inner cylinder and the cylinder body becomes longer or shorter, achieving self-locking while lifting, but the weight of the inner cylinder and the weight of the components connected to the inner cylinder directly act on the output of the servo motor On the end, it is easy to cause damage to the servo motor and affect the service life of the servo motor. Contents of the invention [0003] Aim...
