DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0039] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Example 1

[0041] The following reference Figure 1-Figure 7 As shown, combined with a specific embodiment, the present invention further illustrates that a slag discharge device for shaft construction is provided. Figure 1 As shown, it includes a sliding support mechanism 1, a wellhead support mechanism 2, a rotating disk 3, multiple groups of slag scraping mechanisms 4, multiple groups of lateral conveying mechanisms 5, and a longitudinal conveying mechanism 6 vertically arranged at the center of the shaft. Figure 2 , Figure 3As shown, the sliding support mechanism 1 includes a support frame 11, which is slidably installed in the shaft, and a plurality of groups of abutting members 12 for abutting against the shaft wall are circumferentially distributed on the support frame 11; the wellhead support mechanism 2 includes a support plate 21 and a support ring 22 concentrically arranged outside the support plate 21, and a plurality of support rods 23 are connected between the support ring 22 and the support plate 21, and a lowering assembly 24 for lowering the sliding support mechanism 1 into the shaft is arranged on the support plate 21; the rotating plate 3 is rotatably arranged on a side of the support frame 11 facing the bottom of the shaft, and a rotating member 31 for driving the rotating plate 3 to rotate is arranged on the support frame 11. Figure 4 , Figure 5 As shown, multiple groups of shovel mechanisms 4 are distributed at the bottom of the rotating disk 3 along the circumferential direction of the rotating disk 3. The shovel mechanisms 4 include a support seat 41, which is arranged along the radial direction of the rotating disk 3. The support seat 41 is provided with multiple shovel buckets 42 and a flip member 43 for driving the multiple shovel buckets 42 to flip simultaneously; multiple groups of transverse conveying mechanisms 5 are arranged one by one on one side of the support seat 41 and are used to convey the slag in the shovel buckets 42 toward the center of the rotating ring; the longitudinal conveying mechanism 6 includes a screw conveyor 61, which is slidably arranged in the wellhead support mechanism 2 along the vertical direction, and a receiving tray 62 for receiving the slag in the transverse conveying mechanism 5 is arranged at the bottom of the screw conveyor 61. It should be noted that the height of the receiving tray 62 is lower than the height of the shovel bucket 42 and the transverse conveying mechanism 5, so as to ensure that the transverse conveying mechanism 5 can smoothly convey the slag to the receiving tray 62. Therefore, before the shovel operation, it is first necessary to drill a hole at the center of the shaft to leave space for the installation of the receiving tray 62.

[0042] The wellhead support mechanism 2 is installed at the wellhead position of the vertical shaft to support the overall structure. The support frame 11 is lowered to a specified depth in a specified well through the lowering component 24, and then the multiple sets of clamping members 12 on the support frame 11 are started simultaneously, so that the multiple sets of clamping members 12 are pressed against the well wall of the vertical shaft at various positions at the same time to achieve the positioning effect on the support frame 11. The rotating disk 3 is driven to rotate by the rotating member 31, so that the shoveling mechanism 4 scoops up the slag while moving with the rotating disk 3, and then the shoveling bucket 42 is driven to rotate by the flipping member 43 and pours the slag into the horizontal conveying mechanism 5. The horizontal conveying mechanism 5 is started to convey the slag in the direction close to the center of the rotating ring, and the slag falls into the receiving tray 62 at the bottom of the screw conveyor 61. The screw conveyor 61 is started to convey the slag entering the receiving tray 62 vertically upward to the outside of the wellhead. Since multiple groups of slag shoveling mechanisms 4 shovel slag at the same time, multiple shoveling buckets 42 pour the slag into the corresponding horizontal conveying mechanism 5 immediately after shoveling the slag, and multiple groups of horizontal conveying mechanisms 5 convey the slag to the screw conveyor 61 at the same time, and the screw conveyor 61 continuously conveys the slag to the outside of the wellhead. Compared with the slag discharge by the bucket method, the slag discharge efficiency is greatly improved; compared with the slag discharge by the downward falling method, there is no need to excavate a slag transportation channel at the bottom of the shaft in advance; compared with the mud slag discharge, there is no requirement for the fluidity of the slag, and the slag discharge process does not require water resources.

[0043] Reference Figure 3 As shown, the abutting member 12 includes an abutting electric cylinder 121, the cylinder barrel of the abutting electric cylinder 121 is fixedly arranged on the support frame 11, and a abutting block 122 is arranged on the piston rod of the abutting electric cylinder 121. The abutting electric cylinder 121 is started and the piston rod of the abutting electric cylinder 121 is moved out of the cylinder barrel, thereby driving the abutting block 122 to move toward the wall of the shaft. When each abutting block 122 abuts against the side wall of the shaft, the positioning function of the support frame 11 can be achieved. Both sides of the abutting electric cylinder 121 are provided with limiting pulleys 123 that abut against the wall of the shaft. The limiting pulleys 123 can improve the smoothness of the support frame 11 during the descent process on the one hand, and can also play a certain protective role for the abutting electric cylinder 121 on the other hand, to prevent the abutting electric cylinder 121 or the abutting block 122 from colliding with the shaft wall during the descent process.

[0044] Reference Figure 4 As shown, the rotating member 31 includes a rotating motor 311, and a driving gear 312 is coaxially connected to the output shaft of the rotating motor 311, and the rotating disk 3 is a geared disk meshing with the driving gear 312. The rotating motor 311 is started to drive the driving gear 312 to rotate, that is, the rotating disk 3 can be driven to rotate, and when the rotating disk 3 rotates, the multiple support seats 41 can be driven to rotate at the same time, so that the multiple shovel buckets 42 installed on the support seats 41 move synchronously to shovel the slag.

[0045] Reference Figure 5As shown, a mounting shaft 411 is welded to the bottom of the support seat 41, and a plurality of shovel buckets 42 are spaced apart on the mounting shaft 411 along the length direction of the mounting shaft 411, and the spacing between two adjacent shovel buckets 42 is smaller than the width of the shovel buckets 42; a flip member 43 is slidably arranged in the support seat 41 along the length direction of the support seat 41, and a plurality of groups of toggle members 44 are arranged at the bottom of the flip member 43 for driving the shovel buckets 42 to slide along the length direction of the mounting shaft 411. After the rotating disk 3 drives the support seat 41 to rotate a specified angle, the shovel bucket 42 is driven to flip through the flip member 43, so that the shovel can be poured into the transverse conveying mechanism 5. When the sum of the rotation angles of the plurality of support seats 41 is 360°, a full cycle of shovel operation is completed. For example, in this embodiment, there are 4 support seats 41, and each support seat 41 rotates 90° to complete a circumference of shovel operation; in other embodiments, the support seats 41 are set to 3, and each support seat 41 rotates 120° to complete a circumference of shovel operation. The moving paths of the shovel buckets 42 at corresponding positions on the support seat 41 together form an annular area, and the moving paths of the shovel buckets 42 at all positions on the support seat 41 form multiple annular areas. The shovel buckets 42 remove the slag in multiple annular areas during their movement. At this time, the shovel buckets 42 between two adjacent annular areas from which the shovel has been removed have not yet been removed. The multiple shovel buckets 42 are driven to move a specified distance at the same time by the moving flip member 43, so that the shovel operation can be performed on the shovel in the annular area that has not yet been removed. By making the distance between two adjacent shovel buckets 42 smaller than the width of the shovel buckets 42, it is ensured that the width of the shovel bucket 42 after movement can be greater than the width of the annular area from which the shovel has not yet been removed, thereby ensuring that the shovel range can cover the annular area that has not yet been removed.

[0046] Reference Figure 5 , Figure 6 As shown, the flipping member 43 includes a sliding seat 431, which is slidably installed in the support seat 41 along the length direction of the support seat 41, and a driving electric cylinder 432 is provided at one end of the support seat 41, and the piston rod of the driving electric cylinder 432 passes through the support seat 41 and is fixedly connected to the sliding seat 431; the toggle member 44 includes two U-shaped toggle plates, which are welded to the bottom of the sliding seat 431 and are respectively located on both sides of the shovel bucket 42. When the sliding seat 431 slides in one direction in the support seat 41, the U-shaped toggle plate can drive the shovel bucket 42 to move along the length direction of the mounting shaft 411; starting the driving electric cylinder 432 drives the sliding seat 431 to slide a specified distance along the length direction of the support seat 41, and the U-shaped toggle plate located at the bottom of the support seat 41 can drive the shovel bucket 42 to move the same distance. Since the relative position between the sliding seat 431 and the shovel bucket 42 remains unchanged, the shovel bucket 42 can still be driven to flip after the movement.

[0047] Reference Figure 6As shown, a driving rod 433 is rotatably arranged in the sliding seat 431, and a driving motor 434 for driving the driving rod 433 to rotate is arranged at one end of the sliding seat 431; a plurality of driving gears 435 are arranged on the driving rod 433, and a sleeve 421 is arranged on the shovel bucket 42, and a driven gear 422 meshing with the driving gear 435 is arranged on the sleeve 421. When the driving motor 434 is started and the output shaft of the driving motor 434 drives the driving rod 433 to rotate, the driving gear 435 installed on the driving rod 433 rotates synchronously, thereby driving the plurality of driven gears 422 to rotate synchronously, so that the sleeve 421 drives the shovel bucket 42 to flip, so as to pour the shovel bucket 42 into the horizontal conveying mechanism 5.

[0048] Reference Figure 5 , Figure 6 As shown, the top opening of the scrap bucket 42 near the conveying trough 51 is provided with an arc-shaped closing plate 423, which is hingedly provided on the scrap bucket 42, and both sides of the scrap bucket 42 are hingedly provided with an opening and closing electric cylinder 424 for opening the arc-shaped closing plate 423. In the initial state, the arc-shaped closing plate 423 on the scrap bucket 42 is located at a position obliquely above the scrap bucket 42; when the flip member 43 drives the scrap bucket 42 to rotate a specified angle in a direction away from the horizontal conveying mechanism 5, the arc-shaped closing plate 423 is located at a position obliquely below the scrap bucket 42, and at this time, opening the arc-shaped closing plate 423 can allow the material to fall out of the slag.

[0049] Furthermore, a reinforcement seat 45 is welded on the rotating disk 3 and on the top of each support seat 41. The transverse conveying mechanism 5 includes a conveying trough 51 and a conveying belt 52 arranged in the conveying trough 51. Connecting rods 53 are provided at both ends of the conveying trough 51. The connecting rod 53 is an L-shaped rod and the end of the connecting rod 53 away from the conveying trough 51 is slidably arranged on the reinforcement seat 45. A pressure piece 54 is provided between the conveying trough 51 and the support seat 41. The pressure piece 54 is used to make the conveying trough 51 have a tendency to move in a direction close to the shovel bucket 42 to just below the support seat 41. In the initial state, the conveying trough 51 is located on the bottom side of the support seat 41 under the abutment of the shovel bucket 42. When the shovel bucket 42 flips upward at a specified angle away from the conveying trough 51, the conveying trough 51 moves toward the direction close to the shovel bucket 42 under the action of the pressure piece 54 and finally moves to the bottom of the support seat 41. At this time, the opening originally located obliquely above the shovel bucket 42 is tilted downward and aligned with the conveying trough 51. Opening the arc-shaped closing plate 423 can allow the slag to fall onto the conveyor belt 52 in the conveying trough 51, and be transported by the conveyor belt 52 to the screw conveyor 61.

[0050] Reference Figure 5 , Figure 6As shown, a first touch switch 55 for starting the conveyor belt 52 is provided at the corner position of the connecting rod 53, and a second touch switch 425 for starting the opening and closing electric cylinder 424 is provided on the shovel bucket 42. When the flip member 43 drives the shovel bucket 42 to rotate to abut against the support seat 41, the pressing member 54 synchronously drives the conveying trough 51 to move to the right below the support seat 41. At this time, the first touch switch 55 turns on the conveying motor of the conveyor belt 52, and the second touch switch 425 turns on the opening and closing electric cylinder 424 to open the arc-shaped closing plate 423, and the slag falls from the opening of the shovel bucket 42 onto the conveyor belt 52, and the conveyor belt 52 continuously conveys the slag to the screw conveyor 61.

[0051] Reference Figure 1 , Figure 2 As shown, there are two groups of lowering components 24, and the two groups of lowering components 24 are symmetrically arranged on both sides of the support plate 21. The lowering components 24 include a lifting motor 241, a mounting seat 242 is arranged on the support plate 21, and a lifting plate 243 is rotatably arranged on the mounting seat 242. The lifting motor 241 is arranged at one end of the mounting seat 242, and the output shaft of the lifting motor 241 is coaxially connected with the lifting plate 243. A lifting rope 244 is wound around the lifting plate 243, and one end of the lifting rope 244 away from the lifting plate 243 is fixedly connected to the support frame 11. Starting the lifting motor 241 drives the lifting plate 243 to rotate and unwinds the lifting rope 244, that is, the support frame 11 can be moved downward in the shaft as a whole.

[0052] Reference Figure 2 , Figure 7 As shown, a climbing conveyor 25 is provided on the wellhead support mechanism 2, the lowest end of the climbing conveyor 25 is located on the support plate 21, and the highest end of the climbing conveyor 25 is located outside the vertical shaft, so as to further convey the slag output from the outlet end of the screw conveyor 61. The slag transport vehicle is driven to the bottom of the highest end of the climbing conveyor 25, so that the slag can be conveniently collected and transported. A flexible material guide channel 7 is provided at the outlet end of the screw conveyor 61, so as to smoothly guide the slag into the climbing conveyor 25 to avoid spillage. A sliding seat 71 is provided at the bottom end of the flexible material guide channel 7, and the sliding seat 71 is slidably connected to the frame of the climbing conveyor 25, and a tightening bolt 72 is threadedly connected to the sliding seat 71. When the depth of the shaft changes and slag discharge operations need to be performed at different depths, the height of the top of the screw conveyor 61 will change. By changing the position of the sliding seat 71 on the frame of the climbing conveyor 25, the flexible material guiding channel 7 of the same length can adapt to the change in the height of the outlet end of the screw conveyor 61 within a certain range.
