[0021] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the accompanying drawings in the embodiments of the utility model, so as to have a further understanding of the concept of the utility model, the technical problems solved, the technical features constituting the technical solutions and the technical effects brought about.

[0022] like Figure 1 As shown, a single-person foundation pit excavation device includes a first support frame 1, a second support frame 2, a slideway 3, a slider 4, a fixed pulley 5, a soil hopper 6, a traction rope 7 and a tying rope 8;

[0023] A first support frame 1 is arranged in the foundation pit;

[0024] The second support frame 2 is arranged outside the foundation pit;

[0025] The slideway 3 is tilted, one end of which is connected to the first support frame 1 and the other end of which is connected to the second support frame 2;

[0026] A slider 4 is slidably disposed on the slideway 3, and a hook 9 is provided at the bottom of the slider 4;

[0027] The soil hopper 6 is open at the top and bottom, and the top is connected to the hook 9 through a triangular hanger 10;

[0028] A tying rope 8, one end of which is arranged in the foundation pit, and the other end is connected to the lower part of the soil hopper 6 to complete the sealing of the lower part of the soil hopper 6;

[0029] A fixed pulley 5 is arranged on the slideway 3 outside the foundation pit;

[0030] One end of the traction rope 7 is arranged in the foundation pit, and the other end is connected to the slider 4 after passing through the fixed pulley 5, so as to drive the slider 4 to move on the slideway 3.

[0031] When using the device, firstly, a first support frame 1 is set up in the foundation pit, and a second support frame 2 is set up outside the foundation pit. Due to the height difference between the inside and outside of the foundation pit, the slideway 3 arranged between the first support frame 1 and the second support frame 2 is arranged to be inclined. The operator stands in the foundation pit, and the soil hopper 6 slides down into the foundation pit along the slideway 3 through the slider 4 under the influence of gravity. The operator uses the tying rope 8 to tie and seal the bottom of the soil hopper 6. The operator puts the excavated waste soil into the soil hopper 6, pulls the traction rope 7, and After the fixed pulley 5 changes the direction of the force, it drives the sliding block 4 to rise upward along the slideway 3 to the outside of the foundation pit. The operator pulls the tie rope 8 to loosen it, the lower part of the soil hopper 6 opens, and the waste soil falls to the outside of the foundation pit to complete the transportation; after the operator loosens the traction rope 7, the soil hopper 6 falls back into the foundation pit, and the above operations are repeated to complete the excavation of the foundation pit and the transportation of waste soil, effectively reducing the number of excavation personnel for each foundation pit from 2 to 4 people to at least 1 person and zero mechanical equipment, without affecting the construction efficiency, thereby greatly reducing the cost of manual excavation of the foundation pit.

In this embodiment, the limit block 11 is provided at the bottom of the slide 3, and when the slider 4 slides downward, it is pressed by the limit block 11 when it slides to the limit block 11 and no longer moves downward, so the operator does not need to pull the traction rope 7 to adjust the position of the soil hopper 6, and the soil hopper 6 is in a suitable position, which is convenient for the operator to load.

[0033] like Figure 1 As shown, as a preferred embodiment, the second support frame 2 is a tripod support. In this embodiment, in order to improve the stability of the device, the second support frame 2 is set as a tripod support.

[0034] like Figure 1 As shown, as a preferred embodiment, the legs of the first support frame 1 can be raised and lowered. In this embodiment, a plurality of adjustment holes are provided on the legs of the first support frame 1. When different heights are required, a cross bar is used to insert the adjustment holes of different heights, and different adjustment holes can be selected according to the height of the foundation pit.
