Description

Technical Field

[0001] The present application relates to the technical field of bucket wheel machines, and in particular to a limiting device and a limiting method for a bucket wheel stacker reclaimer. Background Art

[0002] The driving device of the bucket wheel excavator is responsible for the normal operation of the bucket wheel excavator. It is composed of a bearing seat, planetary gears, a reducer, a hydraulic coupling, an electric motor, a pin wheel, etc. These devices are installed on both sides of the bucket wheel excavator to achieve simultaneous driving of both sides. This driving method greatly improves the stress conditions of the roller, which is of great help to the unloading of the bucket wheel excavator.

[0003] In the actual working process, the roller of the bucket wheel excavator may not rotate in circles. This is because the coal ash in the bucket is not unloaded cleanly during the coal-taking process, and the next coal-taking is carried out. In the process, coal powder will gather around the roller of the guide roller group, which increases its friction and causes it to not rotate normally. The damage to the guide roller group bearing is also due to the entry of coal powder into the bearing structure, which causes excessive friction with it during operation, thus causing damage. When the bucket stops rotating, it will rotate again due to inertia, and the motor will be easily damaged. Summary of the invention

[0027] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0028] like Figures 1 to 7As shown, the present invention provides a limiting device for a bucket wheel stacker and reclaimer, comprising a conveyor bed 1, a bucket 2 and a motor 3. A base 12 is welded on the outer wall of the conveyor bed 1, and the motor 3 is detachably connected to the base 12. The motor 3 is connected to the bucket 2 through a linkage shaft 10. A limiting mechanism 11 is arranged between the linkage shaft 10 and the base 12. A pushing mechanism 13 is overlapped in the input direction of the limiting mechanism 11, and a pressing mechanism 14 is arranged in the input direction of the pushing mechanism 13. The pressing mechanism 14 is arranged between the linkage shaft 10 and the base 12. A pulley 5 is welded on the linkage shaft 10, and a transmission belt 4 is sleeved on the pulley 5. The other end of the transmission belt 4 is sleeved on the pulley 5 of a linkage rod 6. The linkage rod 6 is rotatably connected to a fixed seat 7, and the fixed seat 7 is detachably connected to the outer wall of the conveyor bed 1. A transmission mechanism 8 is arranged at the output end of the linkage rod 6, and a reset mechanism 9 is arranged on the transmission mechanism 8. The reset mechanism 9 is detachably connected to the outer wall of the conveyor bed 1, and the output end of the transmission mechanism 8 corresponds to the side wall of the bucket 2. The motor 3 is connected to the bucket 2 through the linkage shaft 10, and the motor 3 can drive the bucket 2 to transmit, and the bucket 2 can dig materials. A support 111 is provided on the linkage shaft 10, and a bayonet 112 is provided on the support 111. When the linkage shaft 10 rotates normally, the frame 144 will be pushed by the large gear 141, and the frame 144 will be away from the top seat 131, and the clamping head 117 will be away from the bayonet 112, and the clamping head 117 will not affect the normal rotation of the linkage shaft 10, and the bucket 2 will be blocked due to the accumulation of materials. When it is unable to rotate, the large gear 141 will stop rotating along with the linkage shaft 10. Due to the inertia of the bucket 2, the linkage shaft 10 and the bucket 2 will rotate in the opposite direction. When rotating in the opposite direction, the protrusion 142 on the frame 144 will immediately insert into the teeth of the large gear 141. At this time, the frame 144 will push the top seat 131 at the same time, and the clamping head 117 will immediately be clamped into the clamping mouth 112, thereby realizing the limiting of the linkage shaft 10. At this time, the bucket 2 will remain stable and will not rotate again, thereby avoiding damage to the components and facilitating subsequent maintenance.

[0029] The transmission mechanism 8 includes a worm 801, which is meshed with a worm wheel 802, a connecting rod 806 is welded on the worm wheel 802, and the connecting rod 806 is rotatably connected to the limit seat 803. A half gear 807 is provided on the output end of the connecting rod 806, and the half gear 807 is meshed with a rack 805. The output end of the rack 805 is detachably connected with a hammer seat 804. Through the meshing of the worm 801 and the worm wheel 802, the linkage rod 6 drives the worm 801 to rotate, which will drive the worm wheel 802, and the worm wheel 802 will drive the half gear 807 through the linkage rod 6, and the half gear 807 will drive the rack 805 to move, so that the rack 805 drives the hammer seat 804 to beat the bucket 2.

[0030] The worm 801 is welded to the output end of the linkage rod 6, the worm 801 and the linkage rod 6 are arranged in a straight line, the connecting rod 806 on the worm wheel 802 and the linkage rod 6 are arranged in a cross shape, the connecting rod 806 is connected to the limit seat 803, the connecting rod 806 is arranged vertically as a whole, and the rack 805 overlaps the outer wall of the conveyor bed 1. The limit seat 803 can realize the bearing of the connecting rod 806, and the connecting rod 806 can rotate at the limit rod position.

[0031] By arranging a support platform 12 on the conveyor bed 1, the support platform 12 can carry the motor 3 and other components.

The clamping head 117 is telescopically connected in the outer rod 113. The outer rod 113 slides on the support plate 134 through the sliding rod 132. One end of the sliding rod 132 is connected to the guide rod 133. The second spring 135 on the guide rod 133 will drive the sliding rod 132 away from the bayonet 112, and the clamping head 117 will remain away from the bayonet 112. A top seat 131 is arranged on the sliding rod 132, and a frame 144 is arranged in the input direction of the top seat 131. The frame 144 Connected to the vertical rod 145, the third spring 146 on the vertical rod 145 will push up the frame 144. The torsion of the third spring 146 is greater than the torsion of the second spring 135. The frame 144 can drive the push rod 143 to push the top seat 131, and the clamping head 117 can be inserted into the bayonet 112 to limit the support 111. The linkage shaft 10 can be limited, and the bucket 2 can finally be limited. When the bucket 2 does not rotate due to the inability to discharge materials, the clamping head 117 can be inserted into the bayonet 112 to limit the position, thereby ensuring that the bucket 2 remains stable and does not reset, so as to facilitate subsequent maintenance. When the bucket 2 rotates normally, the large gear 141 will push down the frame 144, so that the frame 144 will not push the top seat 131, and the bucket 2 can move normally. By setting, it can be limited when a failure occurs in the bucket 2, thereby protecting the safety of other components.

[0032] The reset mechanism 9 includes a socket 902, which is detachably connected to the outer wall of the conveyor bed 1.

The first crossbar 901 and the second crossbar 903 are respectively located at the upper and lower sides of the socket 902, and the first crossbar 901 is sleeved with a corresponding reset spring 904. When the first crossbar 901 and the second crossbar 903 are connected to the rack 805, the rack 805 will move with the first crossbar 901 and the second crossbar 903. When the first crossbar 901 is sleeved with the reset spring 904, the reset spring 904 will pull the rack 805 to reset. After the half gear 807 rotates one circle, it can push the rack 805 again, thereby realizing the reciprocating movement of the rack 805.

[0034] The limiting mechanism 11 includes a support 111, on which a corresponding bayonet 112 is provided, a clamping head 117 is inserted in the input direction of the bayonet 112, an inner rod 114 is welded to the clamping head 117, one end of the inner rod 114 is slidably connected to the outer rod 113, the cross-section of the outer rod 113 is U-shaped, a baffle 115 is provided on the inner rod 114 inside the outer rod 113, and a first spring 116 is sleeved on the inner rod 114. By setting the clamp head 117, the clamp head 117 can be inserted into the bayonet 112 to limit the support 111. When the inner rod 114 is installed on the clamp head 117, one end of the inner rod 114 can be installed on the outer rod 113, and the inner rod 114 can be retracted along the outer rod 113. The first spring 116 is sleeved on the inner rod 114 outside the outer rod 113. The first spring 116 can keep the position of the clamp head 117 stable. When the clamp head 117 moves between the bayonet 112 on both sides of the support 111, the clamp head 117 has space for expansion and contraction and will not collide with the support 111. With the activity of the support 111, the clamp head 117 can enter the bayonet 112, so that the clamp head 117 can continue to move when it cannot enter the bayonet 112 at one time.

[0035] The diameter of the inner rod 114 is smaller than the diameter of the clamp 117, the diameter of the baffle 115 is larger than the diameter of the inner rod 114, the diameter of the outer rod 113 is larger than the diameter of the clamp 117, the first spring 116 is located between the clamp 117 and the outer rod 113, one end of the first spring 116 is detachably connected to the clamp 117, the other end of the first spring 116 is detachably connected to the outer rod 113, and the diameter of the baffle 115 is the same as the inner diameter of the outer rod 113.

[0036] The pushing mechanism 13 includes a support plate 134, on which a slide bar 132 is slidably connected, an outer rod 113 is welded to one end of the slide bar 132, the outer rod 113 has the same diameter as the slide bar 132, and the slide bar 132 is L-shaped as a whole. A guide bar 133 is inserted at the lower end of the slide bar 132, and a second spring 135 is sleeved on the guide bar 133. A top seat 131 is detachably connected to the other end of the slide bar 132, and the output end of the top seat 131 is triangular.

Through the pushing of the convex seat 142 by the large gear 141, the frame 144 always moves downward, and the frame 144 will not drive the push rod 143 to push the top seat 131. When the large gear 141 stops rotating following the linkage shaft 10, the large gear 141 will not continue to push the convex seat 142 downward. When the convex seat 142 moves between the teeth of the large gear 141, the frame 144 will move up, thereby pushing the top seat 131, and the top seat 131 will drive the clamping head 117 to insert into the clamping port 112, thereby realizing the rapid limiting of the support 111, thereby realizing the rapid limiting of the bucket 2.

[0038] By welding the pulley 5 on the linkage shaft 10, the transmission belt 4 can be sleeved on the pulley 5, and the other end of the transmission belt 4 can be sleeved on the pulley 5 of the linkage rod 6, so that the motor 3 can drive the bucket 2 and the linkage rod 6 to rotate at the same time.

When the half gear 807 rotates one circle, it will not be engaged with the rack 805, and the rack 805 will be pulled by the reset spring 904 and reset, so that the hammer seat 804 can hammer the bucket 2 back and forth, and the bucket 2 is hammered and vibrates to facilitate the shedding of materials. By setting up, a large amount of material can be prevented from accumulating, thereby reducing the number of times that the bucket 2 does not rotate.

When the clamp head 117 is inserted into the bayonet 112, the support 111 can be limited. The linkage shaft 10 on the support 111 will be limited, and the bucket 2 will not rotate. S2: A pulley 5 is welded on the linkage shaft 10, and a transmission belt 4 is sleeved on the pulley 5. The other end of the transmission belt 4 can be sleeved on the pulley 5 of the linkage rod 6.

The third spring 146 on the vertical rod 145 will push the frame 144 upward. The torsion of the third spring 146 is greater than the torsion of the second spring 135. The frame 144 can drive the push rod 143 to push the top seat 131, and the clamping head 117 can be inserted into the bayonet 112 to limit the support 111, the linkage shaft 10 can be limited, and the bucket 2 can finally be When the bucket 2 does not rotate due to the inability to discharge materials, the clamp head 117 can be clamped into the clamp port 112 for limiting, thereby ensuring that the bucket 2 remains stable and does not reset, so as to facilitate subsequent maintenance. When the bucket 2 rotates normally, the frame 144 will be pushed down by the large gear 141, so that the frame 144 will not push the top seat 131, and the bucket 2 can move normally. By setting, the bucket 2 can be limited when a failure occurs, thereby protecting the safety of other components. By welding the pulley 5 on the linkage shaft 10, the transmission belt 4 can be sleeved on the pulley 5, and the other end of the transmission belt 4 can be sleeved on the pulley 5 of the linkage rod 6, and the motor 3 can simultaneously drive the bucket 2 and the linkage rod 6 to rotate. The linkage rod 6 is provided with a worm 801. The worm 801 will eventually realize the rotation of the half gear 807 by transmitting the worm wheel 802. The half gear 807 will drive the rack 805 to hammer the bucket 2. When the half gear 807 rotates one circle, it will not mesh with the rack 805. The rack 805 will be pulled by the reset spring 904 and reset, so that the hammer seat 804 can hammer the bucket 2 back and forth. The bucket 2 is hammered and vibrates to facilitate the shedding of materials. By setting, a large amount of material can be prevented from accumulating, thereby reducing the number of times that the bucket 2 does not rotate.
