[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] like Figure 1 As shown in Embodiment 1 of this utility model, a movable deep foundation pit axis guide device includes a bracket 1 and a plumb bob 6 mounted on the bracket 1. The bracket 1 is used to erect the deep foundation pit axis guide device at the top of the foundation pit, facilitating the plumb bob 6 to fall into the foundation pit for axis guide work. Figure 4 As shown, the support 1 is equipped with a rope support assembly 8 to support the rope 61 of the plumb bob 6, facilitating the placement of the rope 61 on the support 1 and allowing the plumb bob 6 to be lowered into the pit from a suitable position. Furthermore, the rope support assembly 8 is movably mounted on the support 1 to allow for adjustment of the position of the plumb bob 6. Figure 2 As shown, a rope adjusting member 5 is provided on the support 1 at a position away from the rope support assembly 8, i.e., at the outer end of the support 1, for fixing the end of the rope 61 and for winding and unwinding the rope. The end of the rope 61, i.e., the end away from the sinker 6, is fixed to the rope adjusting member 5 and the rope is wound and gathered onto the rope adjusting member 5. The rope 61 extends horizontally until it passes through the rope support assembly 8, and then hangs down into the pit under the action of the sinker 6. The rope adjusting member 5 can also be used for winding and unwinding the rope, thereby adjusting the height of the sinker 6.

[0034] Furthermore, the support 1 has a cross-shaped structure, comprising four horizontal support rods positioned within the water surface. These four horizontal support rods are vertically connected to form a cross shape. Each of the four horizontal support rods is equipped with a plumb bob 6, a rope adjusting component 5, and a rope support assembly 8, allowing for simultaneous axial line installation in four directions. In this embodiment, the rope adjusting component 5, the rope support assembly 8, and the plumb bob 6 are sequentially arranged on each horizontal support rod from the outer end towards the center of the pit. The rope 61 is positioned along the length of the horizontal support rod, extending to the rope support assembly 8 at the very end before drooping into the pit.

[0035] Example 2 differs from Example 1 in that, as Figure 1 , Figure 3 and Figure 4 As shown, the bracket 1 is also equipped with a scale 3. In this embodiment, a scale 3 is provided on each of the four horizontal support rods. The length direction of the scale 3 is set along the direction of the horizontal portion of the rope 61, that is, the length direction of the horizontal support rod. When adjusting the position of the rope support assembly 8, the scale 3 can be used as a reference to easily determine the descent position of the adjustment plumb bob 6.

[0036] Example 3 differs from Example 1 in that the rope support assembly 8 includes an adjustable fixing member for connecting to the bracket 1 and a rope threading limiting member 82 disposed on the adjustable fixing member. The rope threading limiting member 82 has a through hole for the rope 61 to pass through. In this example, as... Figure 1 As shown, at least two rope support assemblies 8 are provided, one of which is located near the plumb bob 6 to limit the downward position of the plumb bob 6; the rest are located in the middle of the horizontal support rod and / or near the rope adjusting member 5, and are located between the rope adjusting member 5 and the rope support assembly 8 to support the rope.

[0037] Specifically, such as Figure 7 As shown, the adjustable fixing component includes a mating U-bolt 83 and a fixing plate 81 for securing it to the bracket 1. The U-bolt 83, with its opening facing upwards, is secured to the horizontal support rod from bottom to top. The fixing plate 81 has two holes for the upper end of the U-bolt 83 to pass through, allowing it to be fitted onto the U-bolt 83 from top to bottom, thereby securing the horizontal support rod between the fixing plate 81 and the U-bolt 83. A fastening nut 84 is provided on the U-bolt 83 to secure the fixing plate 81, thus securing the horizontal support rod of the bracket 1. The rope-threading limiting component 82 is a ring, fixed to the upper middle part of the fixing plate 81.

[0038] Example 4 differs from Example 1 in that, as Figure 6 As shown, the rope adjusting member 5 includes a fixed support 51 for connecting the bracket 1 and a roller 52 rotatably connected to the fixed support 51. The roller 52 is used to fix the end of the rope 61, that is, the end away from the sinker 6. At the same time, the rope 61 can also be wound around the roller 52.

[0039] Furthermore, such as Figure 6 As shown, the fixed support 51 is an L-shaped support plate. One side of the L-shaped support plate, i.e., the horizontal part, is horizontally mounted on the bracket 1, and the horizontal part is detachably connected to the bracket 1. In this embodiment, the horizontal part is bolted to the horizontal support rod of the bracket 1. The other side of the L-shaped support plate, i.e., the vertical part, is used to connect a roller 52. In this embodiment, the roller 52 is provided with a rotating shaft, and the roller 52 is rotatably connected to the rotating shaft. One end of the rotating shaft is provided with an external threaded post, which is inserted into a through hole provided on the vertical part of the L-shaped support plate and tightened with a nut.

[0040] Furthermore, such as Figure 6 As shown, the other side of the roller 52, that is, the side away from its axis of rotation, is provided with an eccentrically mounted movable rocker arm 53 for rotating the roller 52, thereby for the winding and unwinding of the line.

[0041] Example 5 differs from Example 1 in that the bracket 1 further includes a leveling component 4 for adjusting the horizontality and a level bubble 7 for monitoring the horizontality. Figure 2As shown, the leveling component 4 is located at the outer end of the horizontal support rod of the bracket 1, and the leveling component 4 is adjustablely connected to the horizontal support rod, making it convenient for operators to adjust the levelness of the horizontal support rod at the top edge of the pit. In this embodiment, the leveling component 4 is located near the rope adjusting member 5, and the leveling component 4 is located on the side of the rope adjusting member 5 away from the plumb bob 6.

[0042] Furthermore, such as Figure 5 As shown, the leveling assembly 4 includes leveling plates 43 clamped on the upper and lower sides of the support 1 and height adjustment supports passing through the leveling plates 43. Each leveling assembly 3 contains two leveling plates 43, which are arranged parallel to each other and located on the upper and lower sides of the horizontal support rod, respectively. Each leveling plate 43 has a through hole, allowing the height adjustment support to pass through. The lower end of the height adjustment support contacts the top of the pit, supporting the horizontal support rod. The height adjustment support has external threads for mounting a leveling nut 42. Tightening the leveling nut 42 clamps the upper and lower leveling plates 43 onto the horizontal support rod. Simultaneously, adjusting the relative position of the leveling nut 42 on the height adjustment support adjusts the support height of the horizontal support rod, thus leveling the support 1. In this embodiment, the height adjustment support uses an inverted U-bolt 41. After the inverted U-bolt 41 passes through the holes of the two leveling plates 43 from top to bottom, it is tightened and fixed by the leveling nut 42, and then the horizontal support rod is clamped by the upper and lower leveling plates 43. In addition, the upper part of the inverted U-bolt 41 forms a handle to facilitate the movement of the deep foundation pit axis guide device.

[0043] Furthermore, the outer ends of the four horizontal support rods are equipped with leveling bubbles 7 to monitor the levelness of the deep foundation pit axis guide device.

[0044] Example 6 differs from Example 1 in that, as Figure 1 As shown, a connecting rod 2 is connected between adjacent horizontal supports of the bracket 1 to improve the rigidity of the bracket.
