Description

Technical Field

[0002] In coal mining operations, supports are one of the key equipment in fully mechanized mining working faces. Traditional supports rely primarily on the pressure provided by the hydraulic system to maintain support force during the support process. However, this approach has some limitations. On the one hand, hydraulic systems are prone to leakage. Once the hydraulic oil leaks, the support force of the supports will decrease, affecting the stability of the roof, and thus endangering the safety of underground workers and the normal operation of coal mining operations. On the other hand, the maintenance of hydraulic systems is relatively complex, requiring regular inspection and replacement of seals and hydraulic oil, which increases equipment maintenance costs and downtime. Therefore, research on electric supports has become a new support direction.

[0003] However, when supporting, most of the existing electric supports are fixed to the base plate, which makes the telescopic range of the support rod small, and the supporting range of the support is small, thereby reducing the use range of the entire device. At the same time, when in use, the existing supports are prone to failure because the electric control rod relies solely on electric control, resulting in poor support stability.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) The present invention can drive the snap gear to rotate through the snap motor, thereby driving the rack to move, thereby driving the snap shaft to move, and thus inserting it into the hole on the snap disk, thereby positioning the chuck positioning block and the movable top buckle, thereby achieving the purpose of self-locking, thereby ensuring the self-locking effect, and at the same time, the snap rod can be extended to allow the snap rod to be inserted into the inside of the snap hole, thereby preventing the rack from moving, thereby ensuring the self-locking effect and the accuracy of the self-locking;

[0017] (2) The present invention can drive the movable top buckle to move by extending and retracting the support rod, thereby changing the angle between the lifting rod and the movable top buckle. At this time, due to the upper measuring needle and the upper measuring disk at the bottom of the upper measuring shaft, the angle between the lifting rod and the movable rod can be monitored by the upper measuring camera, thereby ensuring the monitoring accuracy.

[0018] (3) The present invention rotates the support rod around the support buckle when the support rod is extended or retracted, thereby causing the lower locking rod to rotate along the support buckle. When the positioning shaft rotates to the required angle and is less than the next angle corresponding to the hole on the positioning disk, the lower locking rod extends and is clamped into the hole of the positioning disk. At this time, the positioning shaft continues to rotate, thereby causing the positioning scale plate to rotate. As a result, the fine-tuning ring and the fine-tuning spring prevent the fine-tuning block from rotating. When the fine-tuning is completed, the fine-tuning rod controls the fine-tuning buckle to move, thereby clamping with the fine-tuning teeth, thereby achieving fine-tuning of the angle, thereby ensuring the accuracy of the locking and the stability of the locking.

[0019] (4) The present invention can drive the stabilizing main gear to rotate through the stabilizing motor, thereby driving the stabilizing sub-gear to rotate, thereby causing the stabilizing plate to rotate, so that the stabilizing plate is close to the ground, thereby ensuring the stability of the entire device. At the same time, if the entire device needs to be moved, the stabilizing motor continues to work, so that the stabilizing plate continues to rotate, so that the moving wheel is close to the ground, thereby supporting the entire device to leave the ground, thereby facilitating the movement of the entire device. At the same time, the device can clean impurities on the bottom of the base plate through the scraper, thereby ensuring the stability of the base plate and the horizontality of the base plate, thereby ensuring the support effect;

[0020] (5) The present invention can drive the stabilizing shaft to rotate downward through the stabilizing rod, thereby driving the stabilizing tube to rotate downward, thereby driving the bottom drill bit to rotate downward, and further drive the side drill shaft to rotate outward through the side drill rod, thereby driving the side drill bit to rotate, thereby fixing the stabilizing plate to the ground, thereby ensuring that the bottom plate is fixed to the ground, thereby ensuring the stability of the bottom plate, and thus ensuring the stability of the entire device.
