[0041] 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 only part of the embodiments of the present invention, rather than all the embodiments.

[0042] Reference Figure 1-2 , an ultra-deep shaft earthwork lifting device, including a transfer bracket 1 and an open pod 2.

[0043] Among them, the transfer bracket 1 is set in the transfer area on the ground; the open pod 2 is lifted and moved by the vertical transportation equipment 3.

[0044] During the specific installation, a suitable area is selected in the transfer channel for installing the transfer bracket 1; the installation position of the transfer bracket 1 is aligned with the transportation road to facilitate the arrival of dump trucks and the receipt of earthwork.

[0045] It can be understood that the lower space of the transfer bracket 1 should be larger than the height and width of the dump truck to allow the vehicle to dock and load soil.

[0046] Specifically, the transfer bracket 1 includes a support frame 11 and a crossbeam 12 .

[0047] There are two support frames 11 , and the crossbeam 12 is fixed on the top ends of the two support frames 11 to form a stable support structure.

[0048] At the same time, a boot-shaped support leg 4 is provided at the rear end of the bottom of the open pod 2 to cooperate with the crossbeam 12 and be hooked on the crossbeam 12 to form a hinged state.

[0049] It can be understood that the boot-shaped leg 4 is L-shaped, including a vertical section and a horizontal section; the vertical section is fixedly connected to the bottom of the open pod 2, and the horizontal section is located at the lower end of the vertical section and extends forward; during lifting, the boot-shaped leg 4 is hooked on the crossbeam 12.

[0050] It can be understood that, in order to ensure the stability of the hinged state, a plurality of boot-shaped legs 4 are provided; the plurality of boot-shaped legs 4 are arrayed in a row and evenly distributed.

[0051] Preferably, two boot-shaped legs 4 are provided, and the two boot-shaped legs 4 are symmetrically arranged at the center position of the open pod 2 .

[0052] In some embodiments, the support frame 11 is an A-shaped support structure.

[0053] like Figure 1 As shown, the support frame 11 is assembled and welded by multiple channel steels; two support frames 11 are symmetrically arranged, and a crossbeam 12 made of steel pipe is arranged at the top to fully ensure the overall strength and reliability.

[0054] In some embodiments, a concrete foundation 14 is provided at the lower end of the support frame 11 for fixation.

[0055] It is understandable that other forms, such as expansion bolt connection, direct burial, etc., can also be used to fix the support frame 11 and keep it in a stable state.

[0056] In some embodiments, a vertical guide rod 13 is provided on the upper side of the crossbeam 12 to provide position guidance for the operator during the earth lifting process.

[0057] like Figure 1 As shown, the guide rod 13 is fixed on the crossbeam 12; similarly, the guide rod 13 can also be fixed on the support frame 11; so as to facilitate observation by the operator and not affect the position of the open pod 2.

[0058] In some embodiments, a vertical support leg 5 is provided at the bottom front end of the open pod 2 .

[0059] The vertical legs 5 are flush with the lower end surfaces of the boot-shaped legs 4 so as to maintain stability when placed on the ground for earth loading.

[0060] A plurality of vertical legs 5 are provided, and the plurality of vertical legs 5 are arranged in a row and evenly distributed.

[0061] Preferably, two vertical legs 5 are symmetrically arranged at the center of the open pod 2.

[0062] In some embodiments, a traction rope 6 is provided on the vertical leg 5 .

[0063] The staff at the bottom use the traction rope 6 to assist in adjusting the position of the open pod 2 so as to hook the boot-shaped legs 4 onto the crossbeam 12 for dumping and transporting the earth in place.

[0064] In some embodiments, the open pod 2 is welded by channel steel and steel plate hull; the channel steel is used as the hull frame and stiffening ribs, and the steel plate is used as the hull, which effectively enhances the rigidity of the pod structure and prevents deformation of the pod structure during lifting operations; similarly, the vertical support legs 5 and the boot-shaped support legs 4 can be assembled and welded by channel steel; at the same time, two hanging ears are provided on both sides of the open pod 2, which are connected to the vertical transportation equipment 3 through guide beam slings.

[0065] It is understandable that the volume of the open pod 2 can be designed according to demand; the transfer bracket 1 and the open pod 2 can be manufactured in a processing plant or a construction site.

[0066] A method for hoisting earthwork in an ultra-deep vertical shaft comprises the following steps.

[0067] S1, install vertical transportation equipment 3: select vertical transportation equipment 3 according to on-site layout conditions.

[0068] Among them, tower cranes or gantry cranes can be selected to meet the actual needs of deep and large foundation pits.

[0069] S2, install the transfer bracket 1: select the transfer position and fix the transfer bracket 1.

[0070] S3, mounting the open pod 2: mounting the open pod 2 on the lifting end of the vertical transport equipment 3.

[0071] S4, soil collection and hoisting: After the soil is collected in the deep foundation pit, the open pod 2 is hoisted by the vertical transportation equipment 3 and moved to the transfer bracket 1.

[0072] S5, adjustment state: the operator operates the traction rope 6 to assist in adjusting the posture of the open pod 2, with the help of the rear boot-shaped legs 4 engaging with the crossbeam 12 to form a hinge.

[0073] S6, dumping: using the gravity of the open pod 2 and the rope of the vertical transport equipment 3 to complete the earth dumping operation.

[0074] S7, loop: loop steps S4-S6 to complete the earthwork lifting operation.

[0075] It is understandable that two open pods 2 can also be used in combination to achieve uninterrupted continuous excavation, further improving efficiency.

[0076] In step S4, the operator of the vertical transport device 3 uses the guide rod 13 to assist in confirming the lifting position, which is more accurate and efficient.

[0077] The open pod 2 and the transfer bracket 1 can be manufactured and installed on site.

[0078] The present invention has the following beneficial effects:

[0079] 1. The device is simple to make, easy to obtain materials, and easy to implement on the construction site;

[0080] 2. The device has strong applicability and is suitable for lifting earthwork or materials in deep and large foundation pits;
