Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a bored cast-in-place pile guiding device. Background Art

[0002] Bored piles refer to piles that are made by mechanically drilling, squeezing soil with steel pipes or digging with human hands in the foundation soil. A steel cage is placed in the pile by a crane and concrete is poured. During the process, a large crane is needed to lift the pile body. The crane has high power consumption, slow movement, and low working efficiency, and it is impossible to directly lift and install the pile body.

[0003] The existing patent discloses a bored cast-in-place pile guide device (publication number: CN208328933U). During use, the pile lifting rope buckle can be pulled to pull up the pile lifting frame, saving the crane cost. However, after the column is pulled up, the push screw needs to be manually turned to force the fixing plate to fix the pile body. During this process, it takes a long time and the pile body cannot be automatically fixed. Therefore, the utility model proposes a bored cast-in-place pile guide device. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-3 The utility model provides a technical solution for a bored pile guiding device: a bored pile guiding device, comprising a guard arm 1, and also comprising: a pile lifting frame 2, the pile lifting frame 2 is an arc-shaped plate-like structure, a movable pin 3 is arranged at the connection between the pile lifting frame 2 and the guard arm 1, and a movable connection is formed between the pile lifting frame 2 and the guard arm 1 through the movable pin 3; an automatic clamping assembly 8, the automatic clamping assembly 8 comprises an electric push rod 81, a pressure sensor 82 connected to the output end of the electric push rod 81, a fixing plate 83 connected to the detection end of the pressure sensor 82, an anti-slip strip 84 arranged on one side of the fixing plate 83, a guide rod 85 arranged on the other side of the fixing plate 83, a limit block 86 connected to the end of the guide rod 85, a guide hole 87 and an auxiliary hole 88 opened in the guard arm 1.

[0026] Among them, a fixed connection is formed between the baffle 4 and the pile-lifting frame 2, the number of the protective frames 5 is several groups and distributed in an array, the number of the pile-lifting rope buckles 6 is two groups and distributed symmetrically, the pile-lifting rope buckles 6 are connected to the end of the pile-lifting frame 2, the number of the pile-lifting guide blocks 7 is two groups and distributed symmetrically, the pile-lifting guide blocks 7 are connected to the upper end of the guard arm 1, the base 9 is fixedly connected to the guard arm 1, and the base 9 is located at the upper end of the borehole, which is conducive to placing the pile body into the interior of the pile-lifting frame 2 by a forklift, blocking it through the protective frame 5, and then conveniently pulling up the pile-lifting frame 2, so that the pile body enters the interior of the guard arm 1, and is convenient to move and fall into the borehole.

[0027] In addition, the number of electric push rods 81 is several groups and distributed in an array, the output end of the electric push rod 81 is adapted to the auxiliary hole 88, the output end of the electric push rod 81 is fixedly connected to the pressure sensor 82, the detection end of the pressure sensor 82 is fixedly connected to the fixed plate 83, the fixed plate 83 is an arc-shaped plate structure, the number of anti-slip strips 84 is several groups and distributed in an array, the anti-slip strips 84 are fixedly connected to the fixed plate 83, the guide rod 85 is fixedly connected to the limit block 86 and the fixed plate 83, and the guide rod 85 is adapted to the guide hole 87, which is conducive to automatically clamping the pulled-up pile body.

[0028] The guide device for bored piles has the following steps: during the working process, the pile body is placed inside the pile lifting frame 2 and is limited and blocked by the protective frame 5. When it is necessary to pull up the pile lifting frame 2 and the guard arm 1, the pulling rope is tied to the outside of the pile lifting rope buckle 6 and inserted into the inside of the pile lifting guide block 7. The pile lifting frame 2 is pulled up by manpower or mechanical equipment, so that the pile lifting frame 2 rotates along the movable pin 3, so that the baffle 4 is limited until the pile body enters the inside of the guard arm 1, and then it is clamped by the automatic clamping component 8, and a forklift is inserted into the steel bar gap at the uppermost end of the pile body. The automatic clamping component 8 is released, and the pile body is driven by the forklift to move downward. When the running track of the forklift reaches the end point, the pile body is fixed by the automatic clamping component 8, the output end of the forklift is moved out, and then inserted into the steel bar gap at the uppermost end of the pile body when it rises, and the pile body is lowered in sequence to make it completely enter the borehole, which is convenient for the subsequent cement pouring.

[0029] It should be noted that, through the setting of the automatic clamping component 8, when the pile body is clamped, the output end of the electric push rod 81 moves along the inside of the auxiliary hole 88, and at the same time drives the pressure sensor 82 and the fixed plate 83 to move, and then drives the guide rod 85 to move along the inside of the guide hole 87. The limit block 86 has a limiting effect, so that the fixed plate 83 contacts the pile body. At this time, the anti-slip strip 84 has an anti-slip effect, and the pressure sensor 82 continuously monitors the clamping force. When the clamping force reaches the set value, the output end of the electric push rod 81 stops running, and the pile body is automatically clamped. The clamping force is controllable, and no manual operation is required, thereby improving the clamping efficiency.
