Detailed Description of the Invention

[0042] The following further describes the present invention in detail with reference to the drawings, so that those skilled in the art can implement it according to the description in the specification.

[0043] It should be understood that the terms such as "having", "comprising", and "including" used herein do not exclude the presence or addition of one or more other elements or their combinations.

[0044] As Figures 1 - 3 shown, the present invention provides an inclined shaft construction device, including:

[0045] A track 1, which is arranged in the inclined shaft and is inclined along the length direction of the inclined shaft;

[0046] A lifting mechanism, which is arranged at the end of the track 1 close to the inclined shaft wellhead;

[0047] A trolley 2, which includes wheels 3. The wheels 3 are arranged on the track 1, and the trolley 2 is connected to the lifting mechanism through a rope 4.

[0048] An emergency braking mechanism, which includes:

[0049] A limiting rod 5, which is parallel to the track 1 and has a length not less than that of the track 1. The limiting rod 5 is located outside the wheels 3.

[0050] A driving member, which drives the limiting rod 5 to move away from the wheels 3 or abut against the wheels 3.

[0051] In the above technical solution, generally, the entrance of an inclined shaft is at a higher position and the bottom is at a lower position. Therefore, the end of the track 1 at the wellhead is the high end, and the position at the bottom of the well is the low end. The present application does not limit the lifting mechanism. The lifting mechanism is mainly used to pull the rope 4 on the trolley 2. By pulling the rope 4, the trolley 2 can move forward or backward along the track 1. The emergency braking mechanism includes a limiting rod 5. The limiting rod 5 can be translated along the direction perpendicular to the length of the track 1 by the driving member. When the trolley 2 needs to be braked, the driving member drives the limiting rod 5 to translate until it abuts against the wheels 3, thereby braking the trolley 2. When the trolley 2 is running normally, the limiting rod 5 is located outside the trolley 2 and does not contact the wheels 3.

[0052] During use, place the items to be transported in the trolley 2, and drive the trolley 2 to transport by operating the lifting mechanism to pull or release the rope 4. When the rope 4 breaks, the trolley 2 will accelerate and slide downward. At this time, the driving member drives the limiting rod 5 to abut against the wheels 3 of the trolley 2 to slow down or even stop the trolley 2, avoiding injury to personnel or damage to items.

[0053] In another technical solution, the track 1 includes two parallel slide rails 6; the trolley 2 includes two I-shaped wheels 3. The two wheels 3 are arranged in one-to-one correspondence with the two slide rails 6. Each wheel 3 is clamped on the corresponding slide rail 6, and each wheel 3 can roll on the corresponding slide rail 6. The main purpose of designing the wheels 3 into an I-shape is to prevent the wheels 3 from derailing when the limiting rod 5 abuts against the wheels 3.

[0054] In another technical solution, the lifting mechanism is arranged on a support frame 7. The lifting mechanism includes a horizontal pipe 8 arranged on the support frame 7, which is perpendicular to the track 1. The horizontal pipe 8 is driven to rotate by a servo motor 9. The end of the rope 4 far from the trolley 2 is connected to the horizontal pipe 8. The support frame 7 of the present application does not involve a specific structure and can be a firm rigid structure, mainly used to fix other structures such as the lifting mechanism. By driving the servo motor 9, the horizontal pipe 8 rotates, and the horizontal pipe 8 can wind up or release the rope 4 to control the operation of the trolley 2.

[0055] In another technical solution, the number of the limiting rods 5 is two, and the two limiting rods 5 are clamped on the outer sides of the two slide rails 6. The specific design of the limiting rods 5 is as Figure 1 shown.

[0056] In another technical solution, the driving member includes:

[0057] A first screw rod 10, which includes three horizontally coaxially arranged first smooth rods 11, and a first threaded rod 12 is horizontally arranged between every two adjacent first smooth rods 11. One end of the first screw rod 10 is connected to the output end of the servo motor 9, and the other end of the first screw rod 10 is connected to the horizontal pipe 8. One end of the horizontal pipe 8 close to the first screw rod 10 is clamped with the first screw rod 10, and the end far from the first screw rod 10 is clamped with the support frame 7. The purpose of designing the clamping connection is that when the rope 4 breaks, the horizontal pipe 8 loses balance under force, and the horizontal pipe 8 can be separated from the first screw rod 10 and the support frame 7;

[0058] A first sleeve 13, which is sleeved on the middle first smooth rod 11 of the first screw rod 10 and is internally provided with internal threads adapted to the first threaded rod 12. The first sleeve 13 is slidably clamped with the support frame 7 along the length direction of the first screw rod 10. The present application does not limit the specific slidable clamping structure between the first sleeve 13 and the support frame 7. It may be that the support frame 7 is recessed inward to form a chute parallel to the length direction of the first screw rod 10. A clamping block is provided on the side wall of the first sleeve 13, and the clamping block is slidably clamped with the chute. The first sleeve 13 is connected to the ends of the two limiting rods 5 close to the first sleeve 13, so as to control the movement of the limiting rods 5;

[0059] A first elastic rod 14, which is perpendicularly arranged to the horizontal pipe 8 and is arranged on the side of the horizontal pipe 8 far from the track 1. A collar 15 is sleeved on the horizontal pipe 8. One end of the first elastic rod 14 is connected to the collar 15. The purpose of designing the collar 15 is that when the horizontal pipe 8 rotates, the first elastic rod 14 can still bring a pulling force in the direction away from the track 1 to the horizontal pipe 8, and the other end is connected to the support frame 7. During the operation of the trolley 2, since the horizontal pipe 8 is clamped between the support frame 7 and the first screw rod 10, and is simultaneously subjected to the pulling force of the first elastic rod 14 in the direction away from the trolley 2 and the pulling force given by the trolley 2, so that the horizontal pipe 8 maintains force balance;

[0060] A first electromagnet, which is arranged on the support frame 7 and is located on the side of the first sleeve 13 and far from the horizontal pipe 8. One side of the first sleeve 13 close to the first electromagnet is made of a magnet material corresponding to the first electromagnet;

[0061] A second electromagnet is provided on the horizontal pipe 8. One side of the first sleeve 13 close to the second electromagnet is made of a magnet material corresponding to the second electromagnet;

[0062] Two second screws 16 are horizontally provided at one end of the track 1 away from the inclined wellhead. A belt drive is provided between the two second screws 16 and the output rod of the servo motor 9. Each second screw 16 includes three horizontally coaxially arranged second smooth rods 17. A second threaded rod 18 is horizontally provided between every two adjacent second smooth rods 17. The specific structure of the second screw 16 is as Figure 1 shown, and the optimal placement method of the two second screws 16 is also as Figure 1 shown. Similar to connecting the two second screws 16 in series through a connecting rod, the output rod of the servo motor 9 only needs to be in belt drive with the connecting rod;

[0063] Two second sleeves 19 are sleeved corresponding to the two second screws 16. Each second sleeve 19 is sleeved on the middle second smooth rod 17 located on the corresponding second screw 16. The two second sleeves 19 are arranged corresponding to the two limiting rods 5. Each second sleeve 19 is connected to the end of the corresponding limiting rod 5. The second sleeve 19 is slidably clamped with the support frame 7 along the length direction of the second screw 16. An internal thread that is screwed with the second screw 16 is provided in the second sleeve 19. The present application does not show the specific sliding clamping structure between each second screw 16 and the support frame 7, that is, the present application does not limit its specific structure. One of the sliding clamping structures is that a chute parallel to the second screw 16 is provided on the support frame 7, and a clamping block is provided on the second sleeve 19. The clamping block is slidably clamped with the chute;

[0064] The driving member is arranged as:

[0065] When the servo motor 9 rotates, it drives the horizontal pipe 8 to rotate, so as to drive the trolley 2 to transport; when the trolley 2 is moving downward, there is a repulsive force between the first electromagnet and the first sleeve 13 and between the second electromagnet and the first sleeve 13. When the rope 4 breaks at this time, the horizontal pipe 8 rotates to separate from the first screw rod 10 and the support frame 7, and under the pulling force of the first elastic rod 14, it moves away from the track 1. The first sleeve 13 is screwed with the first threaded rod 12 in the direction away from the servo motor 9 under the action of the repulsive force of the first electromagnet, and drives the two limiting rods 5 to move together. The movement of the two limiting rods 5 drives the corresponding second sleeves 19 to be screwed with the second screw rods 16 until one of the limiting rods 5 abuts against the wheel 3 of the trolley 2 to slow down or even stop the trolley 2. At this time, the first sleeve 13 is unscrewed from the first screw rod 10 and the second sleeve 19 is unscrewed from the second screw rod 16, that is, at this time the first sleeve 13 moves to the first smooth rod 11 at the outermost end of the first screw rod 10 and stops moving; the second sleeve 19 also moves to the second smooth rod 17 at the outermost end of the second screw rod 16 and stops moving, so that the limiting rod 5 also stops moving, and one of the limiting rods 5 is always in a state of abutting against the wheel 3.

[0066] When the trolley 2 is transporting upward, the first electromagnet and the first sleeve 13 and the second electromagnet and the first sleeve 13 attract each other. When the rope 4 breaks at this time, the process of the driving member running is the same as that when the trolley 2 is transporting downward, except that the first sleeve 13 is screwed with the first screw rod 10 in the direction close to the servo motor 9, and the second sleeve 19 is also screwed with the second screw rod 16 in the direction close to the servo motor 9.

[0067] In another technical solution, annular limiting blocks 20 are formed by protruding outward at each end of the first screw rod 10 and the second screw rod 16, which play a role in limiting the first sleeve 13 and the second sleeve 19.

[0068] In another technical solution, through holes 21 are provided through the side walls at each end of the horizontal pipe 8, the through holes 21 penetrate through the edges of the horizontal pipe 8, and the inner side walls of the horizontal pipe 8 opposite to the through holes 21 are recessed inward to form clamping grooves 22, and the clamping grooves 22 penetrate through the edges of the horizontal pipe 8; clamping blocks corresponding to the clamping grooves 22 are provided on the first screw rod 10 and the support frame 7, and each clamping block passes through the corresponding through hole 21 and is clamped with the corresponding clamping groove 22. The specific structure of the horizontal pipe 8 is as Figure 3As shown, when the rope 4 breaks, the horizontal tube 8 rotates until the through hole 21 faces the track 1. At this time, the horizontal tube 8 is no longer under the tension provided by the rope 4 and is in an uneven force state. The horizontal tube 8 instantly detaches from the first screw 10.

[0069] In another technical solution, the outer wall of the horizontal tube 8 is provided with two protrusions 23, and the two protrusions 23 and the through holes 21 at each end and the slots 22 are evenly spaced along the circumference of the horizontal tube 8; a first force rod 24 is horizontally provided on each protrusion 23, one end of the first force rod 24 is connected to the protrusion 23, and the other end is arranged toward the first sleeve 13, and the second electromagnet is arranged at the end of the first force rod 24 close to the first sleeve 13. The purpose of arranging the first force rod 24, the through hole 21 and the slot 22 in this way is that when the horizontal tube 8 needs to be separated from the first screw rod 10, the first force rod 24 is in a parallel state with the first screw rod 10 and will not block the horizontal tube 8 from leaving. At the same time, the first force rod 24 can also leave. Secondly, the two first force rods 24 are arranged relative to each other, which can give a balanced force to the first sleeve 13 to avoid uneven force.

[0070] In another technical solution, a pair of second force rods 25 are provided at the end of the first sleeve 13 away from the first force rod 24. One end of each second force rod 25 is connected to the support frame 7, and the other end is provided with a first electromagnet. The optimal solution is that a pair of second force rods 25 are arranged opposite to each other, and the two second force rods 25 are arranged one by one with the two first force rods 24, so that the first sleeve 13 is evenly stressed.

[0071] A method for using an inclined shaft construction device is provided, comprising the following steps:

[0072] S1, place the things to be transported in the trolley 2, and operate the lifting mechanism to pull or release the rope 4 to drive the trolley 2 for transportation;

[0073] S2. If the rope 4 breaks during transportation, the driving member drives the limiting rod 5 to abut against the wheel 3 of the trolley 2 to slow down or even stop the trolley 2.
