Detailed Implementation

[0036] Please refer to the attached document. Figure 1 - Figure 5 This application illustrates a safety hoisting device for excavating small-section vertical shafts, which is used to assist in the manual excavation of small-section vertical shafts. It includes: an I-beam 1, a first wire rope 5, a slag unloading platform 3, a connecting steel pipe 2, a drilling platform 4, and an electric hoist 9.

[0037] The top of the I-beam 1 is connected to a first wire rope 5, the top of which is connected to the wire rope of a winch (a hoisting device used in conjunction with the construction site). The top of the unloading platform 3 is fixedly connected to a connecting steel pipe 2. The unloading platform 3 is used to support personnel and tools when unloading slag manually or using a small vertical shaft excavator. The top of the connecting steel pipe 2 is fixedly connected to the I-beam 1, so that the unloading platform 3 is suspended. The drilling platform 4 is located between the unloading platform 3 and the I-beam 1, and the drilling platform 4 is slidably fitted with the connecting steel pipe 2. The drilling platform 4 is used for personnel drilling holes and placing explosives. The electric hoist 9 is fixedly installed with the I-beam 1. The end of the second wire rope 6 of the electric hoist 9 is connected to the drilling platform 4. When the electric hoist 9 works, it pulls / releases the second wire rope 6, causing the drilling platform 4 to slide on the connecting steel pipe 2.

[0038] During use, the entire hoisting platform is moved by a winch (a lifting device used in conjunction with the construction site) to position the slag unloading platform 3 at the shaft opening. The hoisting platform is then slowly lowered into the shaft. The electric hoist 9 pulls / releases the second wire rope 6, causing the drilling platform 4 to slide on the connecting steel pipe 2. The drilling platform 4 is adjusted to the shaft opening position, and personnel stand on it. The electric hoist 9 releases the second wire rope 6, causing the drilling platform 4 to slide down. The drilling platform 4 lands on the drilling platform 2, allowing construction personnel to stand on it. Drilling and explosive installation are carried out on drilling platform 4. After the explosive installation is completed, electric hoist 9 pulls drilling platform 4 upward to the wellhead. After the personnel get off, the entire hoisting device is lifted to a safe position by winch (a lifting device used in conjunction with the construction site) and the explosive is detonated to dig the well. When cleaning up the debris, the entire hoisting device is lifted to the vertical shaft position by winch (a lifting device used in conjunction with the construction site). A small vertical shaft excavator is installed on the slag unloading platform 3 to unload the debris from the bottom through the reserved hole of the slag unloading platform 3.

[0039] In one embodiment, a protective component 10 is installed on the top of the I-beam 1 to prevent falling debris from injuring the workers on the drilling platform 4.

[0040] In one embodiment, the protective assembly 10 includes: a trough frame 1001, a blade 1002, and a first hinge 1003 and a second hinge 1004 that match each other.

[0041] The channel frame 1001 is fixedly installed on the top of the I-beam 1, and the two sides of the channel frame 1001 are fixedly connected with the second hinge 1004. The blade 1002 is semi-circular in shape, and the side of the blade 1002 is fixedly connected with the first hinge 1003. The first hinge 1003 is hinged to the second hinge 1004. Since the side of the I-beam 1 extends beyond the channel frame 1001, the blade 1002 can be restricted from rotating downward, but the blade 1002 can rotate upward.

[0042] like Figure 3 As shown, the protective component 10 unfolds into a circle and is located directly above the drilling platform 4, effectively protecting the construction personnel of the drilling platform 4. When the drilling platform 4 moves upward relative to the I-beam 1, the blade 1002 of the protective component 10 can fold upward to avoid squeezing the construction personnel.

[0043] In one embodiment, two sets of blades 1002 are provided, and the two sets of blades 1002 are symmetrically arranged on both sides of the slot frame 1001, and the two sets of semi-circular blades 1002 form a circle.

[0044] In one embodiment, a first connector 7 is fixedly installed at the top center of the drilling platform 4, and the end of the second wire rope 6 of the electric hoist 9 is connected to the first connector 7.

[0045] In one embodiment, a second connector 8 is fixedly connected to the top of the I-beam 1 and near both ends, and two sets of first wire ropes 5 are provided, with the two sets of first wire ropes 5 respectively connected to two second connectors 8.

[0046] Both the first connector 7 and the second connector 8 are lugs, and the wire rope can be fixed to the lugs using traditional U-shaped fasteners.

[0047] In one embodiment, the slag unloading platform 3 includes: an annular portion 301, with multiple vertically intersecting horizontal frame portions 302 and multiple vertical frame portions 303 fixedly connected to the inner side of the annular portion 301; a plurality of tool openings 304 are formed between the horizontal frame portions 302 and the vertical frame portions 303, and the tool openings 304 allow the excavator's boom to extend downward to clean the debris at the bottom of the shaft.
