Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for building construction, specifically an engineering angle iron pile removal device for pulling out temporary angle iron anchor piles, which is particularly suitable for the rapid recovery of inclined anchor piles in scenarios such as power transmission line construction and tower erection. Background Technology

[0002] Temporary angle iron anchor piles are widely used for temporary guy wire fixing in power, communication, and other engineering projects. Traditional extraction methods rely on manual hammering, which is inefficient and labor-intensive. Although existing patented products use levers or hydraulic mechanisms, they still have the following drawbacks:

[0003] 1. The clamping device requires repeated installation, making operation cumbersome;

[0004] 2. Difficult to adapt to the extraction direction of inclined anchor piles;

[0005] 3. The structure is complex and inconvenient to carry. Summary of the Invention

[0006] The present invention aims to provide a simple and adaptable device for removing angle iron piles, the technical solution of which is as follows:

[0007] Right-angle clamp (2): It is provided with an opening hole, and the rotating shaft (302) of the lever wedge (3) is movably connected to the lever wedge (3). The right-angle clamp (2) and the lever wedge (3) are combined to form a clamp. The clamp can be quickly connected to the angle iron stake (1) or quickly disassembled.

[0008] Lever wedge (3): includes an arc-shaped wedge head (301) and a stiffening plate (303). When prying, the arc-shaped wedge head and the right-angle clamping plate work together to clamp the angle iron stake (1), and automatically release when resetting.

[0009] Support (4): The pivot shaft (401) is welded to the pry bar (5) to provide a stable fulcrum;

[0010] Crowbar (5): The main bar (502) amplifies the prying force through the lever principle and is adapted to different burial depth conditions. Attached Figure Description

[0012] Figure 2 This is a schematic diagram of the various components of this utility model.

[0013] The following numbers are labeled in the diagram: 1-Angle iron stake (the object of this utility model, not a component of this utility model), 2-Right angle clamp, 3-Lever wedge, 301-Arc-shaped wedge head, 302-Rotating shaft, 303-Stretching plate, 4-Bracket, 401-Fulcrum shaft, 5-Crowbar, 501-Connecting shaft, 502-Main bar. Detailed Implementation

[0014] The right-angle clamp 2 separates from the lever wedge 3. The right-angle clamp 2 is inserted along the outer right-angle side of the angle iron pile 1, and then the two openings of the right-angle clamp 2 are inserted back onto the rotating shaft 302 of the lever wedge 3. After adjusting the position of the bracket 4, the pile can be pried out. When prying upwards, the arc-shaped wedge head 301 of the lever wedge 3 presses downwards, clamping the angle iron anchor pile with the right-angle clamp 2. Under the action of the crowbar 5, the angle iron pile 1 is pulled out. Since the length pulled out at one time is limited, the crowbar 5 is lifted upwards again, and the arc-shaped wedge head 301 of the lever wedge 3 rises, releasing the angle iron anchor pile from the right-angle clamp 2. The right-angle clamp 2 and the lever wedge 3 slide down the angle iron pile 1 as a whole. When the crowbar 5 presses down again, the second upward pull is performed. This process is repeated several times until the angle iron pile 1 is completely pulled out.

[0015] In the angle iron pile removal device, the right-angle clamp 2 has two openings for fitting the rotating shaft 302 of the lever wedge 3. The outer shape of the right-angle clamp 2 matches the outer right-angle side of the angle iron pile 1. The lever wedge 3 includes an arc-shaped wedge head 301, a rotating shaft 302, and a stiffening plate 303. The arc-shaped wedge head 301 is axially connected to the right-angle clamp 2 through the rotating shaft 302. The stiffening plate 303 is used to enhance the structural strength of the lever wedge 3. The bracket 4 has a fulcrum shaft 401 for fixing the main bar 502 of the crowbar 5. One end of the crowbar 5 is movably connected to the lever wedge 3 through the connecting shaft 501, and the other end is welded to the fulcrum shaft 401 of the bracket 4. The main bar 502 amplifies the prying force by increasing the lever length.

[0016] The opening of the right-angle clamp 2 of the angle iron pile removal device is matched with the rotating shaft 302 of the lever wedge 3, so that the right-angle clamp 2 can rotate along the rotating shaft 302 during the prying process, thereby clamping or releasing the angle iron pile 1.

[0017] The arc of the arc-shaped wedge 301 of the angle iron pile removal device fits with the inner right-angle side of the angle iron pile 1. When prying, it forms a clamping effect with the right-angle clamp plate 2 through downward pressure, and automatically releases when resetting.

[0018] The fulcrum shaft 401 of the bracket 4 of the angle iron pile removal device is welded to the main bar 502 of the crowbar 5 to form a stable fulcrum structure, ensuring efficient transmission of prying force.

[0019] The angle iron pile removal device achieves rapid assembly and disassembly through a split design, and is suitable for the extraction of angle iron piles with different inclination angles and burial depths.
