Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shearer drum processing, and particularly relates to a shearer drum processing and overturning platform. BACKGROUND

[0002] The shearer drum is the most core working component of the shearer, and is directly responsible for breaking the coal wall and loading the coal onto the scraper conveyor, and the basic structure comprises a drum body, spiral blades, a tooth seat and the like. When the shearer drum is welded and processed, the spiral blades are usually welded on the drum body first, and then the tooth seat is welded on the spiral blades and the drum body.

[0003] In the process of welding the spiral blades, the spiral blades are first spot-welded on the drum body, the drum body is then fixed by the fixing mechanism of the overturning platform, the welding seam is in the best flat welding position by the overturning mechanism of the overturning platform, and the long-welding seam welding is performed on the spiral blades that have been spot-welded on the drum body. Since only spot welding is performed between the drum body and the spiral blades, the strength is very low. For small spiral blades, the drum body and the spiral blades are usually fixed by a clamp. For heavy blades, in order to prevent the self-weight from causing sagging and thus causing a gap with the drum body, a supporting tool such as a jack and a supporting wheel is added for support. However, the clamping and supporting positions of the clamp and the supporting tool are relatively fixed, which will interfere with the subsequent welding processing, and it is inevitable to frequently pause the welding, remove the clamp on the welding path, and then reposition and arc, which will affect the welding quality and processing precision. Secondly, in the dynamic process of overturning and position welding of the drum body and the spiral blades, the support points required by the spiral blades are constantly changing, and the static supporting tool cannot adapt to the dynamic welding process, resulting in unreliable and unstable supporting effect, and thus affecting the welding quality and efficiency. Furthermore, there is no overturning platform for continuously clamping and supporting and self-adapting position adjustment of the drum body and the spiral blades, which is inconvenient for ensuring that the spiral blades and the drum body are always in close welding state during the entire welding process.

[0004] Therefore, in order to ensure that the spiral blades and the drum body are always close, and improve the welding quality, the present application provides a shearer drum processing and overturning platform. SUMMARY

[0047] With reference to Figure 7 andFigure 10 The locking assembly 53 comprises a double-headed hydraulic rod 531, the double-headed hydraulic rod 531 is symmetrically installed inside the rectangular shell frame 321, the inside of the rectangular shell frame 321 is symmetrically and slidingly connected with a trapezoidal plate 532 at the center of the adaptive block 323, the upper and lower two telescopic ends of the double-headed hydraulic rod 531 are fixedly connected with the trapezoidal plate 532, the side of the trapezoidal plate 532 close to the supporting ring 522 is in an inclined shape matched with the wedge block 524, and the side of the trapezoidal plate 532 close to the adaptive block 323 is fixedly connected with a close strip 533.

[0048] After the two turnover clamping mechanisms 2 clamp the cylinder from both sides, the arc-shaped supporting frame 4 supports the bottom of the spiral blade (as shown in Figure 1 and Figure 4 ), the telescopic end of the hydraulic cylinder 311 moves upwards, driving the upper and lower sliding plates 312 and the traction frame 313 to move upwards, and the two triangular movable frames 314 are moved from the initial position away from each other to the position close to each other (as shown in Figure 5 and Figure 6 ) by the traction of the upward movement of the traction frame 313, driving the corresponding clamping assembly 32 and the stabilizing mechanism 5 to move close to the cylinder and the spiral blade.

[0049] When the upper and lower sliding plates 312 move to the highest position, the upper and lower sliding plates 312 support the arc-shaped bottom of the arc-shaped supporting frame 4, improving the supporting strength of the arc-shaped supporting frame 4, and the clamping assembly 32 and the arc-shaped supporting frame 4 form a triangular stable structure, enhancing the connection stability between the cylinder and the spiral blade, preventing the spiral blade from sagging due to its own weight, and avoiding the gap between the spiral blade and the cylinder.

[0050] The clamping assembly 32 clamps the spiral blade, so that the spiral blade closely contacts the side wall of the cylinder, and the specific situation is as follows: the triangular movable frame 314 drives the rectangular shell frame 321 to move towards the cylinder and the spiral blade, the rectangular shell frame 321 drives the movable groove 322, the connecting column 324, and the U-shaped clamping piece 325 to move, the U-shaped clamping piece 325 clamps the spiral blade from both sides, the rolling balls 326 on the inner wall of the U-shaped clamping piece 325 roll on the outer wall of the spiral blade, the rolling balls 326 on the outer wall of the U-shaped clamping piece 325 close to the outer wall of the cylinder roll on the outer wall of the cylinder, and the two U-shaped clamping pieces 325 in front of and behind the corresponding spiral blade respectively surround and dynamically clamp part of the spiral blade, so that the spiral blade closely contacts the cylinder.

[0051] When the motor driving mechanism drives the clamped cylinder and spiral blade to be turned and displaced for welding, the spiral blade is displaced relative to the U-shaped clamping piece 325, the rolling balls 326 roll to reduce friction, and the adaptive block 323 adaptively slides left and right in the movable groove 322 with the rotation of the spiral blade, so as to ensure that the U-shaped clamping piece 325 dynamically clamps and supports the spiral blade in the whole operation process (as shown inFigure 11 、 Figure 12 and Figure 13 The adjustment can be made in time according to the overturning state, so that the welding quality and efficiency are not affected.

[0052] It should be noted that the top wall of the arc-shaped support frame 4 is smooth, and the friction with the spiral blade is small, so that the rotation of the spiral blade is less affected.

[0053] When the rotation stops and before welding, the upper and lower telescopic ends of the double-headed hydraulic rod 531 are retracted to the middle part, driving the two trapezoidal plates 532 to move towards the adaptive block 323, and the trapezoidal plates 532 drive the close-together strips 533 to slide downward in the rectangular shell frame 321 until the two close-together strips 533 from the upper and lower directions clamp the adaptive block 323, at which time the position of the adaptive block 323 is locked.

[0054] At the same time, during the movement of the trapezoidal plates 532 up and down the adaptive block 323, the inclined surface of the trapezoidal plates 532 gradually approaches the inclined surface of the wedge-shaped block 524 until it is in close contact and pushes the wedge-shaped block 524, the support ring 522 moves, the support ring 522 drives the sliding block 523 to slide in the sliding groove 521, the support ring 522 drives the side stabilizer 525 and the middle stabilizer 527 to slide in the corresponding side adjusting groove 526 and the middle adjusting groove 528, until the part of the arc-shaped close-together part of the side stabilizer 525 slides out of the inside of the arc-shaped plate of the support stabilizer 51 and further abuts against the side wall of the cylinder, and the part of the rectangular close-together part of the middle stabilizer 527 slides out of the middle adjusting groove 528 and further abuts against the side wall of the spiral blade, at which time the U-shaped clamping part 325, the side stabilizer 525 and the middle stabilizer 527 cooperate to change the self-adaptive dynamic limiting of the cylinder and the spiral blade to fixed clamping, further improving the stability, facilitating subsequent welding processing, and being conducive to improving the welding quality and processing precision.

[0055] It should be noted that the support stabilizer 51 is symmetrically arranged on both sides of the U-shaped clamping part 325, and after the arc-shaped close-together part of the side stabilizer 525 is adjusted, the middle stabilizer 527 and the side stabilizer 525 on the U-shaped clamping part 325 cooperate to form a triangular stabilizing structure at the limited position of the spiral blade, which is conducive to enhancing the stability of the limited position of the spiral blade.

[0056] It should be noted that the close-together strips 533 close to the side wall of the adaptive block 323, the arc-shaped close-together part of the side stabilizer 525 close to the side wall of the cylinder, and the rectangular close-together part of the middle stabilizer 527 close to the side wall of the spiral blade can all be installed with rubber pads to increase the friction and improve the locking strength of the positions of the adaptive block 323, the cylinder, and the spiral blade.

[0057] In the application, the cylinder and the spiral blade are limited and supported from the front, rear and bottom directions by the clamping assembly 32 and the arc-shaped supporting bracket 4 respectively, the front and rear corresponding clamping assemblies 32 surround and dynamically limit the partial segments of the spiral blade respectively, and the clamping assembly 32 and the stabilizing assembly 52 cooperate to change the adaptive dynamic limitation to fixed clamping, thereby further improving the stability; although the application increases the auxiliary clamping mechanism 3, the arc-shaped supporting bracket 4 and the stabilizing mechanism 5 and the like compared with the prior art, the technical scheme of the application does not need to frequently pause welding, remove the clamps and supports on the welding path, and then reposition and arc, and the continuous clamping and supporting and adaptive position adjustment can be realized in the process of the welding machine, thereby improving the production efficiency and quality, and the increased equipment cost of the application compared with the prior art can be completely ignored in terms of long-term economic benefits.
