Description

Technical Field

[0001] The invention relates to the technical field of conveying equipment for high-angle coal seam mining, in particular to an anti-slip anchoring device for a high-angle scraper conveyor. Background Art

[0002] In the prior art, the anti-skid anchoring measures usually use hydraulic single pillars to connect the scraper conveyor with a round link chain and an anchor seat. The structure is relatively simple and requires manual operation in the tunnel, which is time-consuming and labor-intensive and also has certain safety hazards. The safety of mechanized comprehensive mining of steep-angle coal seams has always been a technical problem in the coal mining industry. The scraper conveyors in the steep-angle comprehensive mining and comprehensive caving working faces often rise, slide down, and overturn, which seriously affects the safe production of the working face. Summary of the invention

[0003] The purpose of the present invention is to provide an anti-skid anchor device for a large-angle scraper conveyor, which can effectively prevent the scraper conveyor from rising, sliding, and overturning, and can move forward with the scraper conveyor to ensure safe production in underground large-angle coal seam mining.

[0004] The objective of the present invention is achieved through the following technical solutions:

[0005] An anti-slip anchoring device for a large-angle scraper conveyor, characterized in that it includes a support block, an anchoring jack, a support frame, an anchoring seat, a fixing pin, a connecting plate, a connecting pin, and an anti-falling jack;

[0006] The support frame comprises a pressing block, a support frame body, bolts, and a connecting frame is arranged in the middle of the support frame body;

[0007] The top end of the anchor jack is hinged with a support block, and the bottom end is provided with an anchor seat;

[0008] The two ends of the connecting plate are respectively hinged to the anchor seat and the tail frame by fixing pins;

[0009] The two ends of the anti-falling jack are respectively hinged to the tail frame and the support frame by connecting pins;

[0010] The support frame is arranged at the middle position of the anchor jack;

[0011] The anchor jack, connecting plate, tail frame and anti-falling jack form a four-bar linkage;

[0012] Further, the support block can be adjusted automatically within the tilt range of 0 to 120° of the anchor jack;

[0013] The anti-falling jack is further adjustable within the working surface inclination range of 20 to 45°;

[0014] The number and stroke of the further anchoring jacks and anti-falling jacks can be optimized according to the width of the tail frame and the height of the roadway, and the overall width of the anchoring seat H1 ≤ the width of the tail frame H2;

[0015] Further, the anchoring jack and the anti-falling jack can be a hydraulic cylinder or a pneumatic cylinder, preferably a hydraulic cylinder.

[0016] The beneficial effects of the present invention are mainly manifested in: it can effectively prevent the conveyor of the large-angle fully-mechanized mining and fully-mechanized caving working face from jumping up, sliding down and overturning, and can move with the conveyor, without the need for personnel to enter the return air tunnel to perform anchoring operations, thus realizing automatic control.

[0023] The technical solutions in the embodiments of the present invention are described completely and clearly below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, but not all of them.

[0024] Depend on Figure 1 It can be seen that the anti-slip anchoring device includes a support block 1, an anchoring jack 2, a support frame 3, an anchoring seat 4, a fixing pin 5, a connecting plate 6, a connecting pin 8, and an anti-falling jack 9.

[0025] Depend on Figure 2 It can be seen that the support frame 3 includes a pressing block 31 , a support frame body 32 , and bolts 33 , and a connecting frame 321 is arranged in the middle of the support frame body 32 .

[0026] Depend on Figures 1 to 3It can be seen that the top of the anchor jack 2 is hinged with a support block 1, and the bottom is provided with an anchor seat 4. The two ends of the connecting plate 6 are respectively hinged with the anchor seat 4 and the tail frame 7 by a fixing pin 5. The two ends of the anti-falling jack 9 are respectively hinged with the tail frame 7 and the connecting frame 321 by a connecting pin 8. The supporting frame 3 is arranged in the middle position of the anchor jack 2. The anchor jack 2, the connecting plate 6, the tail frame 7, and the anti-falling jack 9 form a four-bar linkage.

[0027] Depend on Figures 1 to 4 It can be seen that since the support block 1 is an articulated structure, the inclination angle of the anchor jack 2 can be adjusted within the range of 0 to 120°, so that it is always close to the tunnel roof. The anti-falling jack 9 is adjustable within the range of 20 to 45° of the working surface inclination, so that the anchor jack 2 is supported between the tunnel roof and the bottom plate. The number and stroke of the anchor jack 2 and the anti-falling jack 9 can be optimized according to the width of the tail frame and the working surface mining height, and the overall width H1 of the anchor seat 4 ≤ the width H2 of the tail frame. In summary, the anti-skid anchor device for a large-angle scraper conveyor of the present invention can adapt to changes in the working surface inclination and mining height.

[0028] In addition, the anchoring jack 2 and the anti-falling jack 9 can be hydraulic cylinders or pneumatic cylinders, preferably hydraulic cylinders.

[0029] To sum up, the anti-skid anchor device is an integral structure. During the coal mining process, the anti-skid anchor device can move forward with the conveyor. In the anchored state, there is no need for personnel to enter the tunnel for secondary anchoring, which improves the safety and automation level of the coal mining process.
