[0050] The following will be described in detail with reference to the accompanying drawings Figure 1 - the accompanying drawings Figure 3 The present application will be further described in detail.

[0051] The present application provides a vertical shaft soil removal device, referring to Figures 1-3 as shown, comprising a frame 1, a guide rail 2, a crown block 3 and a soil container 4.

[0052] Wherein, the frame 1 spans the vertical shaft wellhead at one end of its length direction and has a support beam 11 erected on the vertical shaft wellhead, and the other end is surrounded by a soil field 1a. The guide rail 2 is erected on the top of the frame 1 along the length direction of the frame 1. The crown block 3 can move along the guide rail 2 and has a liftable hook 31. The soil container 4 is detachably connected to the hook 31 and can discharge soil downward from the bottom.

[0053] As arranged above, after the soil container 4 is filled with soil from the vertical shaft, the soil container 4 can be lifted out of the vertical shaft by the crown block 3, and then the crown block 3 is moved along the guide rail 2 to above the soil field 1a, and the soil is discharged from the bottom of the soil container 4 to the soil field 1a, so that rapid soil transportation is realized, and the working efficiency of the vertical shaft soil removal is improved compared with the traditional soil removal method. At the same time, the support beam 11 is arranged at the vertical shaft wellhead, which is more stable, and can improve the stability of the frame 1 during the operation of the crown block 3. The support beam 11 of the present embodiment is erected on the ring beam at the vertical shaft wellhead.

[0054] As an implementable implementation form, the soil container 4 comprises a cylinder body 41, a cover plate 42 and a locking assembly 43. The cylinder body 41 is open at both upper and lower ends. Two cover plates 42 are provided and are rotatably connected at the lower end opening of the cylinder body 41. When the two cover plates 42 are closed against each other, the bottom of the soil container 4 is closed. The locking assembly 43 is arranged between the cover plate 42 and the cylinder body 41, and is used to lock the closing state of the two cover plates 42. The bottom end of the soil container 4 can be closed by moving the two cover plates 42 close to each other to load soil; and the bottom end of the soil container 4 can be opened by moving the two cover plates 42 away from each other to facilitate soil discharge. The lower part of the cylinder body 41 of the present embodiment has a downwardly tapered circular table-shaped outer wall, which is beneficial to the concentration of soil in the cylinder body 41 being discharged.

[0055] Further, the cover plate 42 is provided with an upwardly extending flange 421, and the flange 421 is provided with a reinforcing groove 422. The outer wall of the barrel 41 is fixed with a reinforcing block 411, and when the cover plate 42 is in the closed state, the reinforcing block 411 is inserted into the reinforcing groove 422 to support the cover plate 42. The flange 421 can improve the sealing capacity of the cover plate 42 to the lower end of the barrel 41, and the insertion of the reinforcing block 411 into the reinforcing groove 422 can support the cover plate 42 and improve the load-bearing capacity of the earth container 4. When the cover plate 42 is in the closed state, the flange 421 is in close contact with the outer wall of the barrel 41. In this embodiment, two reinforcing grooves 422 are provided on each cover plate 42, and the reinforcing grooves 422 are rectangular grooves, and the reinforcing block 411 is a cuboid, and the horizontal dimension of the reinforcing groove 422 is greater than that of the reinforcing block 411, so that the reinforcing block 411 can be inserted into the reinforcing groove 422.

[0056] Secondly, the locking assembly 43 includes a limiting post 431 and a buckle 432. The limiting post 431 is provided with two, which are vertically fixed at one end of the cover plate 42 away from the hinge shaft. The buckle 432 is slidably connected to the barrel 41 along the axial direction of the barrel 41 and has two accommodating grooves 4321. When the two limiting posts 431 are inserted into the two accommodating grooves 4321 respectively, the buckle 432 constrains the distance between the two limiting posts 431. When the two cover plates 42 are closed, the distance between the two limiting posts 431 is the shortest, and the buckle 432 can be sleeved on the two limiting posts 431 by sliding down, so that the positions of the two limiting posts 431 are locked, preventing the earth container 4 from being accidentally opened during loading and transporting. The limiting post 431 of this embodiment is a cylindrical body welded on the flange 421.

[0057] Preferably, the barrel 41 is provided with a dovetail groove 412, and the buckle 432 is provided with a dovetail block 4322, which is slidably inserted into the dovetail groove 412. In this way, the buckle 432 can slide along the axial direction of the barrel 41, and the buckle 432 will not fall off the barrel 41, and the buckle 432 is stable in use.

[0058] In addition, regarding the lifting structure of the earth container 4, the top of the barrel 41 is symmetrically provided with two lifting lugs 44 about the central axis of the barrel 41, and the lifting lugs 44 are connected by a flexible cable 45, and the lifting hook 31 hooks the flexible cable 45 to move the earth container 4. The lifting lugs 44 cooperate with the flexible cable 45 to facilitate the lifting of the earth container 4, and the lifting of the flexible cable 45 by the lifting hook 31 is convenient for balancing the earth container 4. Secondly, by using flexible cables 45 of different lengths, the lifting height of the earth container 4 can be changed. The flexible cable 45 can be a chain, a steel wire rope or a woven rope, as long as it can play a lifting role. The flexible cable 45 of this embodiment is a steel wire rope.

[0059] As an implementable implementation form, the frame body 1 comprises a first portal frame 12, a second portal frame 13, a third portal frame 14 and a structural beam 15. The first portal frame 12 is provided with a support beam 11 at the bottom. The second portal frame 13 is arranged in parallel with the first portal frame 12. The third portal frame 14 is arranged in parallel with the second portal frame 13, and forms a soil field 1a with the second portal frame 13. The structural beam 15 is fixedly connected with the first portal frame 12, the second portal frame 13 and the third portal frame 14 respectively. The three portal frames form a stable whole through the structural beam 15, which can provide a firm installation basis for the guide rail 2, and is beneficial to improve the use stability of the shaft soil extraction device.

[0060] Specifically, cross-stitched reinforcing rods are welded between adjacent portal frames to enhance the overall structural strength of the frame body 1. The two ends of the guide rail 2 are bolted to the top cross beams of the first portal frame 12 and the third portal frame 14 respectively, and are bolted to the lower part of the top cross beam of the second portal frame 13, so that the guide rail 2 is firmly and stably connected.

[0061] Preferably, the soil field 1a has an entrance and exit facing away from the first portal frame 12. The soil field 1a is arranged between the second portal frame 13 and the third portal frame 14, and the entrance and exit are arranged to face away from the first portal frame 12, which can facilitate the transportation of the earthwork in the soil field 1a by the transportation vehicle. Specifically, the soil field 1a is provided with three enclosures, and the side without enclosure is the entrance and exit. The enclosure can be made of wood or steel plate, and is reinforced by steel pipes.

[0062] The shaft soil extraction device of the embodiment can lift the earth extraction container 4 out of the shaft by the crown block 3 after the earth extraction container 4 is filled with earth from the shaft, and then move the crown block 3 along the guide rail 2 to above the soil field 1a, so as to discharge the earth from the bottom of the earth extraction container 4 to the soil field 1a, thereby realizing rapid earth transportation, improving the working efficiency of the shaft soil extraction, and reducing the labor intensity of the operator.
