[0012] This invention also provides a novel mobile coal jacking method for mines, applied to the aforementioned novel mobile coal jacking system, comprising the following steps:

[0013] S1: Driven by the coal chute sliding assembly, the casing retraction assembly releases the wire rope through a winch and moves down along the casing assembly under its own weight, stopping at the outer edge of the lowest end of the casing.

[0014] S2: The motor-driven screw on the casing take-up and release assembly drives the clamp to hook the outer edge of the casing, the coal chute sliding assembly tightens the wire rope, and the lower casing assembly moves up a small distance, so that the hook of the lower casing assembly disengages from the hook groove of the outer casing.

[0015] S3: Under the action of the spring, the hook of the lower sleeve assembly slides back to its original position along the guide groove, and rotates 90 degrees in the direction of the hook.

[0016] S4: The coal chute sliding assembly releases the wire rope, and the lower sleeve assembly extends under the gripping force of the claw of the coal chute sliding assembly and its own gravity. During the extension process, the sleeve hook rotates in the direction and will not get caught in the groove of the outer sleeve during the downward movement.

[0017] S5: When the tail of the lower sleeve assembly reaches the head of its outer sleeve, the limiting block set at the head of the outer sleeve engages with the tail of the slide rail of the lower sleeve assembly, and at the same time, the driving cylinder at the head of the outer sleeve drives the limiting pin to be inserted into the limiting hole of the lower sleeve assembly for locking.

[0018] S6: The slide rail of the lower sleeve assembly moves to drive the flow limiting plate inside the sleeve to open at an angle along the pipe wall, and executes S1 to S6 in sequence to extend the remaining sleeve.

[0019] S7: When all telescopic pipes are in the extended and retracted position, the material is conveyed through the hopper of the coal chute sliding assembly, and the material is buffered by the multi-stage flow limiting plate to reduce the amount of material breakage.

[0020] S8: Driven by the coal chute sliding assembly, the casing take-up and release assembly releases the wire rope through the winch and moves down along the casing assembly under its own weight, stopping when it reaches the outer edge of the casing of the upper casing assembly.

[0021] S9: The motor-driven screw on the sleeve take-up and release assembly drives the gripper head to contact the round handle of the sleeve assembly hook;

[0022] S10: The head drive cylinder of the casing retracts the limit pin, the coal chute sliding assembly tightens the wire rope, and the casing moves upward.

[0023] S11: When the retracted position is reached, the motor drive screw on the coal chute sliding assembly drives the gripper head to press the hook handle tightly, the hook compresses the spring and rotates 90 degrees under the action of the guide groove;

[0024] S12: The coal chute sliding assembly loosens the wire rope, the sleeve retraction assembly retracts the sleeve and moves it down a short distance, the hook is engaged in the hook groove of the uppermost sleeve, the sleeve retraction assembly disengages from the sleeve, and the process of retracting the sleeve continues to be executed from S7 to S11.

[0025] The beneficial effects of the novel mobile coal chuting method and system of the present invention are as follows: By measuring the material level between the lower sleeve assembly and the car or ship hold, the coal chute sliding assembly is controlled to retract the wire rope, driving the sleeve retraction assembly to reach the upper edge of the second-to-last sleeve layer. Simultaneously, it is detected that the first-to-last sleeve layer is empty. The sleeve retraction assembly drives the gripper to clamp the upper edge of the second-to-last sleeve layer, while the pneumatic pin at the upper edge of the first-to-last layer retracts and disengages from the positioning hole. The coal chute sliding assembly continues to retract... The steel wire rope, the sleeve retraction assembly, grips the second-to-last layer of sleeve and retracts it into the last layer of sleeve. As it approaches the retracted position, the gripper and the round-head buckle slide and fasten the hook, causing the hook to rotate. Once the hook engages the hook groove of the last layer of sleeve, the sleeve retraction assembly disengages from the sleeve. Based on the material discharge situation at the site, the remaining sleeves are retracted or extended. After completing this material discharge, the coal chute sliding assembly slides to the next working position. At this time, the gripper of the sleeve retraction assembly... The lower sleeve assembly moves upward a short distance along its upper edge, disengaging from the hook slot. Due to the spring's reset action, the hook rotates 90°, and the sleeve retraction assembly grips the lower sleeve and moves it downward. When the handle of the upper sleeve assembly grasps the sleeve's pull rod's hanging slot and moves a distance, it drives the support rod to open the multiple sets of flow-limiting plates of the lower sleeve assembly. The pneumatic pin on the upper edge of the outer sleeve inserts into the positioning hole for positioning, thereby achieving the extension of the sleeve. This invention utilizes multiple sets of staggered flow-limiting plates... The flow plate slows down the falling height of the material, thus acting as a buffer and reducing the breakage effect of the falling material. The orderly planning of the sleeve assembly's opening and closing sequence ensures the opening and closing function of the flow-limiting plate on the inner wall of the sleeve during contraction and extension. Different hooks and pull rods are designed at both ends of the sleeve to achieve orderly control of the sleeve assembly. The gripping design of the sleeve opening and closing assembly ensures the effective extension and contraction of the sleeve, which can effectively reduce the breakage rate of the material and significantly save economic losses caused by material breakage.

[0051] Please see Figure 14 and Figure 15 The present invention also provides a novel mobile coal jacking method for mining, applied to the novel mobile coal jacking system described above, comprising the following steps:

[0052] S1: Driven by the coal chute sliding assembly 1, the casing retraction assembly 2 releases the wire rope 54 through the winch and moves down along the casing assembly 3 under its own weight, stopping at the outer edge of the lowest casing 6.

[0053] S2: The motor 37 on the casing take-up and release assembly 2 drives the screw to move the clamp hook to grab the outer edge of the casing 6, the coal chute sliding assembly tightens the wire rope 54, and the lower casing assembly 5 moves up a small distance, so that the hook 11 of the lower casing assembly 5 disengages from the hook groove of the outer casing 6.

[0054] S3: Under the action of the spring 12, the hook 11 of the lower sleeve assembly 5 slides and resets along the groove of the guide tube 13, and rotates 90 degrees in the hook direction;

[0055] S4: The coal chute sliding assembly 1 releases the wire rope 54, and the lower sleeve assembly 5 extends under the gripping force of the claw of the coal chute sliding assembly 1 and its own weight. During the extension process, due to the rotation of the direction of the hook 11 of the sleeve 6, it will not be hooked with the groove of the outer sleeve 6 during the downward movement.

[0056] S5: When the tail of the lower sleeve assembly 5 reaches the head of its outer sleeve 6, the limiting block set at the head of the outer sleeve 6 engages with the tail of the slide rail of the lower sleeve assembly 5, and at the same time, the driving cylinder at the head of the outer sleeve 6 drives the limiting pin to be inserted into the limiting hole of the lower sleeve assembly 5 for locking.

[0057] S6: The slide rail of the lower sleeve assembly 5 drives the flow limiting plate 10 inside the sleeve 6 to open at an angle along the pipe wall, and executes S1 to S6 in sequence to extend the remaining sleeve 6.

[0058] S7: When all telescopic pipes are in the extended and retracted position, the material is conveyed through the hopper of the coal chute sliding assembly 1, and the material is reduced in the amount of material breakage by the buffering effect of the multi-stage flow limiting plate 10.

[0059] S8: Driven by the coal chute sliding assembly 1, the casing take-up and release assembly 2 releases the wire rope 54 through the winch and moves down along the casing assembly 3 under its own weight, stopping when it reaches the outer edge of the casing 6 of the upper casing assembly 4.

[0060] S9: The motor 37 on the sleeve retraction assembly 2 drives the screw to cause the gripper head to contact the round handle of the hook 11 of the sleeve assembly 3;

[0061] S10: The head drive cylinder of the sleeve 6 retracts the limit pin, the coal chute sliding assembly 1 tightens the wire rope 54, and the sleeve 6 moves upward.

[0062] S11: When the retracted position is reached, the motor 37 on the coal chute sliding assembly 1 drives the screw to move the gripper head to press the round handle of the hook 11, the hook 11 compresses the spring 12 and rotates 90 degrees under the action of the guide groove 36;

[0063] S12: The coal chute sliding assembly 1 loosens the wire rope 54, the sleeve retraction assembly 2 and the sleeve 6 move down a short distance, the hook 11 is sleeved in the hook groove of the uppermost sleeve 6, the sleeve retraction assembly 2 disengages from the sleeve 6, and the process of retracting the sleeve continues to be executed from S7 to S11.

[0064] In a novel mobile coal hauling method and system of the present invention, by measuring the material level of the lower sleeve assembly 5 and the car or ship hold, the coal chute sliding assembly 1 controls the wire rope 54 to retract and extend, driving the sleeve retraction and extension assembly 2 to reach the upper edge of the second-to-last sleeve 6. At the same time, it is detected that there is no material in the first-to-last sleeve 6. The sleeve retraction and extension assembly 2 drives the grabber 41 to grip the upper edge of the second-to-last sleeve 6, while the pneumatic pin at the upper edge of the first-to-last sleeve... 14. As the coal chute sliding assembly 1 retracts and disengages from the positioning hole 44, the wire rope 54 continues to retract. The sleeve retraction assembly 2 grips the penultimate sleeve 6 and retracts into the penultimate sleeve 6. Just before reaching the retracted position, the gripper 41 and the round-head buckle 32 slide and fasten the hook 11, thereby rotating the hook 11. When the hook 11 engages the hook groove 15 of the penultimate sleeve 6, the sleeve retraction assembly 2 disengages from the sleeve 6. Based on the material feeding situation at the site, the remaining sleeve 6 is fed and unfurled. After the material feeding is completed, the coal chute sliding assembly 1 slides to the next working position. At this time, the gripper 41 of the sleeve feeding assembly 2 grips the upper edge of the lower sleeve assembly 5 and moves it upward a short distance. The hook 11 disengages from the hook groove 15. Due to the reset action of the spring 12, the hook 11 rotates 90°. The sleeve feeding assembly 2 grips the lower sleeve 6 and moves it downward. When the handle 20 of the upper sleeve assembly 4 grips the hanging groove 24 of the pull rod body 21 of the sleeve 6 and moves a distance, the support rod 7 drives the multiple sets of flow limiting plates 10 of the lower sleeve assembly 5 to open. The pneumatic pin 14 on the upper edge of the outer sleeve 6 is inserted into the positioning hole 44 for positioning, thereby realizing the extension of the sleeve 6. The present invention uses multiple sets of staggered flow limiting plates 10 to slow down the height of the material falling, thereby playing a buffering role and reducing the crushing effect of the material falling.

[0065] According to the law of conservation of momentum, the following formula should be followed when material falls from a height: F c T = m(v1 - v0), where: F c The average impulse of the material is T, the collision time between the material and the bottom of the silo or carriage is m, the mass of the material is v1, the velocity of the material at the time of collision is v0, and the initial velocity of the material is v0.

[0066] By F c The formula T = m(v1 - v0) shows that the smaller the collision force of the material, the smaller its breakage rate. Since the mass of the material remains constant and the initial velocity v0 is 0, the material breakage mainly depends on the velocity v1 during the collision and is directly proportional to the velocity v1. Since the material is in free fall, the velocity v1 = gt, where g is the acceleration due to gravity and is a constant. When the falling time t is effectively controlled, i.e., the falling time t is reduced, the collision force F can be reduced. cThis reduces the breakage rate of falling materials.

[0067] This invention uses five flow-limiting plates 10 staggered in a single sleeve 6 to divide the material's descent time into five segments. Each segment requires 1 / 5 of the time it takes for the material to pass through the entire sleeve 6. Assuming that the time required for the material to pass through the entire sleeve 6 without the flow-limiting plates 10 is t, after setting five flow-limiting plates 10, the material's descent time is shortened to 1 / 5t. In the extended and retracted state of the multi-sleeve sleeve 6, due to the action of the flow-limiting plates 10 inside the sleeve 6, the collision force is always maintained at 1 / 5 of the original value, thereby effectively reducing the material breakage rate.

[0068] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.

5. A novel mobile coal chuck method, applied to the novel mobile coal chuck system as described in claim 4, characterized in that, Includes the following steps: S1: Driven by the coal chute sliding assembly, the casing take-up and release assembly releases the wire rope through the winch and moves down along the casing assembly under its own weight, stopping at the outer edge of the lowest end of the casing. S2: The motor-driven screw on the casing take-up and release assembly drives the clamp to grab the outer edge of the casing, the coal chute sliding assembly tightens the wire rope, and the lower casing assembly moves up a small distance, so that the hook of the lower casing assembly disengages from the hook groove of the outer casing. S3: Under the action of the spring, the hook of the lower sleeve assembly slides back to its original position along the guide groove, and rotates 90 degrees in the direction of the hook. S4: The coal chute sliding assembly releases the wire rope, and the lower sleeve assembly extends under the gripping force of the claw of the coal chute sliding assembly and its own gravity. During the extension process, the sleeve hook rotates in the direction and will not get caught in the groove of the outer sleeve during the downward movement. S5: When the tail of the lower sleeve assembly reaches the head of its outer sleeve, the limiting block set at the head of the outer sleeve engages with the tail of the slide rail of the lower sleeve assembly, and at the same time, the driving cylinder at the head of the outer sleeve drives the limiting pin to be inserted into the limiting hole of the lower sleeve assembly for locking. S6: The slide rail of the lower sleeve assembly moves to drive the flow limiting plate inside the sleeve to open at an angle along the pipe wall, and executes S1 to S6 in sequence to extend the remaining sleeve. S7: When all telescopic pipes are in the extended and retracted position, the material is conveyed through the hopper of the coal chute sliding assembly, and the material is buffered by the multi-stage flow limiting plate to reduce the amount of material breakage. S8: Driven by the coal chute sliding assembly, the casing take-up and release assembly releases the wire rope through the winch and moves down along the casing assembly under its own weight, stopping when it reaches the outer edge of the casing of the upper casing assembly. S9: The motor-driven screw on the sleeve take-up and release assembly drives the gripper head to contact the round handle of the sleeve assembly hook; S10: The head drive cylinder of the casing retracts the limit pin, the coal chute sliding assembly tightens the wire rope, and the casing moves upward. S11: When the retracted position is reached, the motor drive screw on the coal chute sliding assembly drives the gripper head to press the hook handle tightly, the hook compresses the spring and rotates 90 degrees under the action of the guide groove; S12: The coal chute sliding assembly loosens the wire rope, the sleeve retraction assembly retracts the sleeve and moves it down a short distance, the hook is engaged in the hook groove of the uppermost sleeve, the sleeve retraction assembly disengages from the sleeve, and the process of retracting the sleeve continues to be executed from S7 to S11.
