[0002] Generally speaking, anti-slide piles are a particularly effective retaining structure in highway construction, especially common in southwestern my country. However, in mountainous areas with narrow, uneven terrain, severe conditions, and weak foundations, large construction equipment often cannot reach the sites. In such cases, manually excavated bored piles are usually used for construction.

[0003] Existing hoisting equipment mostly consists of simple lifting frames (using concrete counterweights) that, in conjunction with electric winches, bring slag buckets and excavated soil from the bottom of manually excavated pile holes to the surface. When the winch lifts the excavated soil to the hole opening, the slag buckets must be manually lifted from the center of the pile hole to the outside before unloading. Construction workers have to operate back and forth near the edge of the pile hole, which is unsafe.

[0051] The working principle is: before use, the operator can open the protective door (62).

[0052] When in use, while the workers are excavating the slag in the hole, the retaining wall (9) is constructed simultaneously. When hoisting the slag from the pile hole (8), the slag bucket (53) is first placed into the hook of the anti-detachment device (52). Then, the operator uses the control equipment to control the winch (51) to drive the wire rope to lift the empty slag bucket (53) off the ground. Next, the operator uses the control equipment to control the sliding device (4) to drive the hoisting assembly (5) connected to it to the top of the pile hole (8). Then, the operator uses the control equipment to control the winch (51) to drive the wire rope to lift the empty slag bucket (53) into the pile hole (8) to fill it with slag. After the slag bucket (53) is full, the operator... Using the control equipment, the winch (51) is used to drive the wire rope to hoist the slag bucket (53) filled with slag to the top of the pile hole (8). Then, the sliding device (4) is used to move the slag bucket (53) filled with slag to the outside of the pile hole (8) for disposal. This completes one cycle of slag excavation and transportation in the pile hole (8). Finally, the operator uses the control equipment to control the sliding device (4) and the winch (51) to place the slag bucket (53) at the bottom of the pile hole (8) for slag loading. The above operation is repeated until the slag excavation and transportation in the pile hole (8) is completed. After all the construction work is completed, for construction safety, the operator only needs to close the protective door (62).

[0053] Throughout the entire implementation process described above, on the one hand, protective components (6) are installed below the lifting frame (2). The protective measures around the lifting frame (2) can prevent objects falling from a height from entering the pile hole (8). At the same time, the protective door (62) is locked when not in operation and opened during operation to facilitate the entry and exit of construction personnel and the hoisting of excavated soil, which greatly improves the safety of construction.

[0054] On the other hand, due to the presence of safety protection equipment (7), workers can deliver fresh air into the pile hole (8) through an air compressor (74) and air supply pipe (75). During construction, a ladder (71) is lowered simultaneously. At the same time, an emergency button (73) and a toxic and harmful gas detector (76) are installed at the bottom of the ladder (71). The emergency button (73) is connected to the safety alarm device (72) installed on the column (21) as a whole. When workers in the pile hole (8) notice abnormal situations such as a sudden increase in groundwater, a continuous rise in the content of toxic and harmful gases, or a collapse of the hole, they can immediately press the emergency button (73) and use the safety alarm device (72) to call for help from people outside the hole. This not only fully ensures the safety of workers and avoids accidents, but also improves the stability of the equipment, increases work efficiency, reduces losses after an accident, and contributes to the long-term development and good social image of the enterprise.

[0055] The beneficial effects of this utility model compared with the prior art are:

[0056] 1. The central suspended load-bearing crossbeam of this utility model is equipped with a sliding device, and a winch is connected to the sliding device. Under the control of the control equipment, the slag can be transported to the outside of the pile hole through the slag bucket. Compared with the previous method of hoisting slag by manual winch, it can greatly reduce the labor burden of the operators and improve efficiency. At the same time, the structure is simple, the operation is quick, and it is safe and reliable.

[0057] 2. This utility model provides a ladder for lowering the pile hole on the hole wall. The ladder is equipped with safety platforms at equal intervals. The ladder is also equipped with a toxic and harmful gas detector and an emergency button, which can call for help to people outside the pile hole in an emergency, further ensuring the safety of workers inside the hole.

[0058] 3. This utility model adopts a portal-type standardized lifting frame. The central suspended load-bearing beam on the top cover of the lifting frame is equipped with a sliding groove. The sliding device is connected to the sliding groove, and the lifting and hoisting components are connected below the sliding device. This enables the slag to be vertically lifted from the bottom of the pile hole to the opening of the pile hole, and then slid to be transported to the outside of the pile hole, which effectively improves the efficiency of slag transportation and slag removal and greatly improves the progress.

[0059] 4. The lifting frame of this utility model is equipped with a canopy on its top cover. The canopy can provide shade and shelter from rain, creating a better working environment for workers inside the hole and preventing rainwater from falling into the pile hole.

[0060] 5. The lifting frame of this utility model is also equipped with a protective component. The surrounding protection can prevent objects falling from a height from falling into the pile hole. At the same time, the protective door can be opened during operation to facilitate the entry and exit of construction personnel and the hoisting of excavated soil. When not in operation, it can be locked to prevent other personnel from accidentally falling into the pile hole.

[0061] 6. The lifting frame base of this utility model is designed with steel bars, which can effectively solve the difficulty that the lifting frame cannot withstand the overall hoisting operation load in soft geological areas, and can also block the surrounding surface water to prevent surface water from entering the hole.

[0062] 7. The lifting frame of this utility model has a simple structure, and is easy to install and dismantle. At the same time, it effectively ensures the safety of operators, greatly improves production efficiency, and all parts can be recycled and reused, which greatly reduces construction costs.

[0063] 8. Because this utility model is equipped with safety protection devices, it can not only ensure the safety of workers and prevent accidents, but also improve the stability of the device, increase work efficiency, reduce losses after accidents, and contribute to the long-term development of enterprises and a good social image.

[0151] The specific steps for using it are:

[0152] During operation, while workers are excavating the excavated soil into the hole, a retaining wall 9 is constructed simultaneously. Fresh air is supplied to the pile hole 8 via an air compressor 74 and an air supply pipe 75, and a ladder 71 is lowered concurrently. An emergency button 73 and a toxic gas detector 76 are installed at the bottom of the ladder 71. The emergency button 73 is integrated with a safety alarm device 72. If workers inside the pile hole 8 notice any abnormalities such as a sudden increase in groundwater, a continuous rise in the content of toxic gases, or a hole collapse, they can immediately press the emergency button 73 and use the safety alarm device 72 to call for help from personnel outside the hole. The pile hole 8 is then hoisted... When handling excavated soil, first, place the excavated soil bucket 53 into the hook of the anti-detachment device 52. After filling the excavated soil bucket 53, use the control equipment to control the winch 51 to drive the wire rope to lift the full excavated soil bucket 53 to the top of the pile hole 8. Then, use the control equipment to control the sliding device 4 to move the full excavated soil bucket 53 horizontally to the outside of the pile hole 8 for disposal. This completes one cycle of excavated soil removal and transportation within the pile hole 8. Subsequently, with the control equipment controlling the sliding device 4 and the winch 51 in coordination, the excavated soil bucket 53 is placed at the bottom of the pile hole 8 for filling with excavated soil. Finally, repeat the above operations until the excavated soil removal and transportation within the pile hole 8 is completed.

[0153] After use, the specific dismantling steps are as follows: First, remove the slag bucket 53, fix the wire rope and anti-detachment device 52, and remove and set aside the ladder 71, emergency button 73, air supply pipe 75, toxic and harmful gas detector 76, etc. Then, disassemble the air compressor 74 from the column 21; then, use a crane to fix the four lifting rings 34 around the top of the canopy frame 6, and then disassemble the bolt assembly and reinforcing connection assembly 23 on the column 21 and the top cover frame 32; after dismantling, hoist the central suspended load-bearing beam 31, the top cover frame 32, the winch 51, the canopy 33, etc. to one side, and then gradually dismantle the column 21, the diagonal support rod 22, the protective plate 61, and the protective door 62; finally, after breaking the lifting frame base 1, remove the embedded connector 11, thus completing the dismantling operation. All parts on the lifting frame 2 can be reused.
