Description

Technical Field

[0001] This utility model relates to the technical field of building construction equipment, and in particular to an urban building piling machine. Background Technology

[0002] Piling machines are used in construction to drive piles into the ground. During pile hole excavation, soil removal is always a critical issue. With some machines, the excavated soil is difficult to clean up, easily accumulating at the connection between the machine's screw drum and frame, affecting subsequent construction operations and requiring additional manpower and resources for cleanup.

[0003] In addition, after the soil is excavated, backfilling often occurs, meaning that the excavated soil falls back into the pile hole, affecting the quality of the pile hole formation and subsequent construction procedures such as cast-in-place piles. Some existing equipment lacks effective measures to prevent backfilling and cannot solve this problem well. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose an urban construction piling machine. The soil removal hole on the outer side facilitates the removal of the extruded soil, optimizes the soil removal process, and avoids soil accumulation that may affect construction operations. During the process of the soil falling after being extruded, it can be pushed away from the pile hole, effectively preventing the removed soil from re-entering the pile hole, ensuring the construction quality of the pile hole, and facilitating the subsequent centralized treatment of the removed soil.

[0006] To achieve the above objectives, this utility model proposes an urban building piling machine, comprising:

[0007] trailer;

[0008] The frame is fixed to the load-bearing seat of the trailer;

[0009] Rotating frame, which is rotatably connected to the machine frame;

[0010] The regulating pump consists of two sets, with one end of the regulating pump rotatably connected to the frame and the other end of the regulating pump rotatably connected to the frame.

[0011] The slide rail is fixed to the inner wall of the rotating frame;

[0012] The threaded blade bearing housing is slidably connected to the slide rail. The center of the threaded blade bearing housing is rotatably connected to the threaded blade. The output end of the threaded blade bearing housing is connected to the threaded blade, and the input end of the threaded blade bearing housing is connected to the rotary motor.

[0013] The screw barrel is fixed to the outer wall of the threaded blade bearing housing. The outer side of the screw barrel has a soil discharge hole. The center of the screw barrel matches the center of the threaded blade. The end of the threaded blade is located on the outside of the screw barrel.

[0014] The anti-soil cover is fixed on the rotating frame and fits onto the outer wall of the screw cylinder. The inner diameter of one end of the anti-soil cover is matched with the outer diameter of the screw cylinder.

[0015] The descent mechanism has a support fixed to the frame, and its moving end is connected to the threaded blade bearing seat.

[0016] This utility model of an urban construction piling machine features a soil removal hole on its outer side, which facilitates the removal of extruded soil, optimizes the soil removal process, and prevents soil accumulation from affecting construction operations. As the soil falls after being extruded, it can be pushed away from the pile hole, effectively preventing the removed soil from re-entering the pile hole, ensuring the construction quality of the pile hole, and facilitating subsequent centralized treatment of the removed soil.

[0017] In addition, the urban building piling machine proposed in the application may also have the following additional technical features:

[0018] Specifically, the lowering mechanism includes a rotating lead screw, which is rotatably connected to the inner wall of the rotating frame via two sets of lead screw bearing seats. A threaded slider is rotatably connected to the outer wall of the rotating lead screw, and the threaded slider is fixedly connected to the threaded blade bearing seat.

[0019] Specifically, hydraulic cylinders are fixed on both sides of the bottom of the rotating frame, and the output end of the hydraulic cylinders is connected to a tripod.

[0020] Specifically, the trailer is equipped with a bracket on its top, which is slidably connected to the frame, and a mechanical spring is installed between the bracket and the frame.

[0021] Specifically, a soil-breaking head is fixed to the bottom surface of the screw cylinder.

[0030] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Rather, the embodiments of this utility model include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0031] The following description, in conjunction with the accompanying drawings, describes an embodiment of the urban building piling machine of this utility model.

[0032] like Figures 1-5 As shown, the urban building piling machine of this utility model embodiment may include:

[0033] Trailer 1.

[0034] Frame 2 is fixed on the load-bearing seat of trailer 1.

[0035] Rotating frame 3 is rotatably connected to frame 2.

[0036] Adjusting pump 4, there are two sets of adjusting pump 4, one end of adjusting pump 4 is rotatably connected to frame 2, and the other end of adjusting pump 4 is rotatably connected to frame 2.

[0037] Slide rail 5 is fixed to the inner wall of the rotating frame 3.

[0038] The threaded blade bearing housing 6 is slidably connected to the track of the slide rail 5. The center of the threaded blade is rotatably connected to the threaded blade. The output end of the threaded blade bearing housing 6 is connected to the threaded blade. The input end of the threaded blade bearing housing 6 is connected to the rotary soil motor. The spiral size of the exposed threaded blade is larger than the size of the threaded blade inside the screw barrel 7. The size of the threaded blade inside the screw barrel 7 fits with the screw barrel 7. The size of the exposed threaded blade is equal to or slightly larger than the size of the threaded blade, so that the screw barrel 7 can drive into the place where soil is to be excavated.

[0039] The screw cylinder 7 is fixed to the outer wall of the threaded blade bearing seat 6. The outer side of the screw cylinder 7 has a soil discharge hole 8. The center of the screw cylinder 7 matches the center of the threaded blade. The end of the threaded blade is located on the outside of the screw cylinder 7. The soil discharge hole 8 is located on the outer side of the screw cylinder 7, so that the rising soil flows out from the outside. The outer side of the screw cylinder 7 is the side of the screw cylinder 7 away from the trailer 1. If the soil is discharged from the rear, the discharge position is the gap between the vehicle body and the screw cylinder 7, and the soil is inconvenient to clean. The soil discharge hole 8 is located on the outer side to facilitate the cleaning of the discharged soil.

[0040] The anti-soil cover 9 is fixed on the rotating frame 3 and is fitted onto the outer wall of the screw cylinder 7. The inner diameter of one end of the anti-soil cover 9 is matched with the outer diameter of the screw cylinder 7. During the process of the removed soil falling, the anti-soil cover 9 pushes the soil away from the pile hole to prevent the removed soil from re-entering the pile hole, which facilitates the handling of the removed soil.

[0041] The descent mechanism 10 is fixed on the frame 2, and the moving end of the descent mechanism 10 is connected to the threaded blade bearing seat 6.

[0042] Specifically, when piling is required, the length of the regulating pump 4 is increased by driving the regulating pump 4. Due to the change in the length of the regulating pump 4, the rotating frame 3 will rotate on the frame 2 until it is perpendicular to the ground. By driving the soil rotating motor and the lowering mechanism 10, the soil rotating motor drives the threaded blades to rotate. The threaded blades contact the ground and break up the soil surface. At the same time, when the screw cylinder 7 descends, the threaded blades inside the screw cylinder 7 will transport the soil into the screw cylinder 7 until it is removed from the soil outlet hole 8 of the screw cylinder 7. After the screw cylinder 7 is completely in the piling position, the screw cylinder 7 is removed and the pile is placed in the pile hole.

[0043] In one embodiment of this utility model, such as Figures 1-3 As shown, the lowering mechanism 10 includes a rotating lead screw 11, which is rotatably connected to the inner wall of the rotating frame 3 via two sets of lead screw bearing seats. A threaded slider 12 is rotatably connected to the outer wall of the rotating lead screw 11. The threaded slider 12 is fixedly connected to the threaded blade bearing seat 6. A lead screw motor is connected to the input end of the lead screw bearing seat. The lead screw motor drives the rotating lead screw 11 to rotate. The threaded slider 12, which is threadedly connected to the rotating lead screw 11, will drive the threaded blade bearing seat 6 to slide on the track of the slide rail 5.

[0044] In one embodiment of this utility model, hydraulic cylinders 13 are fixed on both sides of the bottom of the rotating frame 3. The output end of the hydraulic cylinder 13 is connected to a tripod 14. The tripod 14 can determine the right angle of the rotating frame 3 after the rotating frame 3 rotates and ensure that the tripod 14 is placed stably. The tripod 14 is used to determine the vertical piling angle of the thread blade. When the rotating frame 3 rotates to be perpendicular to the ground, the screw cylinder 7 is moved to the piling position by the trailer 1, and then the tripod 14 is lowered to the ground.

[0045] In one embodiment of this utility model, such as Figure 4 As shown, a bracket 15 is provided on the top of the trailer 1. The bracket 15 is slidably connected to the frame 2. A mechanical spring 16 is provided between the bracket 15 and the frame 2. The bracket 15 is used to support the rotating frame 3 that is placed down. The mechanical spring 16 can absorb the weight of the rotating frame 3.

[0046] In one embodiment of this utility model, such as Figure 5 As shown, a soil-breaking head 17 is fixed on the bottom surface of the screw cylinder 7, which facilitates the screw cylinder 7 to enter the soil layer.

[0047] Specifically, in actual execution, by driving the regulating pump 4, the length of the regulating pump 4 increases. Due to the change in the length of the regulating pump 4, the rotating frame 3 will rotate on the frame 2 until it is perpendicular to the ground. By driving the soil rotating motor and the lowering mechanism 10, the soil rotating motor drives the threaded blades to rotate. The threaded blades contact the ground and break up the soil surface. At the same time, when the screw cylinder 7 descends, the threaded blades inside the screw cylinder 7 will transport the soil into the screw cylinder 7 until it is removed from the soil outlet hole 8 of the screw cylinder 7. After the screw cylinder 7 is completely in the piling position, the screw cylinder 7 is removed and the pile is placed in the pile hole.

[0048] In summary, the urban construction piling machine of this utility model features a soil removal hole on its outer side, which facilitates the removal of the extruded soil, optimizes the soil removal process, and prevents soil accumulation from affecting construction operations. During the process of the soil falling after being extruded, it can be pushed away from the pile hole, effectively preventing the removed soil from re-entering the pile hole, ensuring the construction quality of the pile hole, and facilitating subsequent centralized treatment of the removed soil.
