[0036] Please refer to the attached document. Figures 1-6 This application illustrates a positioning and guiding device for a long casing for bored piles, which is used to ensure accurate positioning and verticality of the steel casing during bored pile construction. Specifically, it includes: a support assembly 1, a bearing frame 2, and a guiding body 3.

[0037] The support frame 2 is fixedly installed inside the bracket assembly 1, and the guide body 3 is fixedly installed with the support frame 2, as follows. Figure 1 As shown, the guide body 3 is supported by the support frames 2 on both sides and is fixed by U-bolts.

[0038] In actual use, the support frame 2 and the bracket assembly 1 are fixedly installed with high-strength bolts, and the height of the support frame 2 is adjusted according to actual usage requirements.

[0039] Specifically, the guide body 3 includes two sets of guide plate groups 301 arranged in parallel and symmetrical arrangement at the top and bottom, a hanger 302 fixedly connected between the two sets of guide plate groups 301, and two symmetrically distributed guide rollers 303 fixedly installed between the two sets of guide plate groups 301.

[0040] The design of the double-layer structure (two sets of guide plates arranged in parallel and symmetrical positions) makes the guidance more stable. In addition, two symmetrically distributed guide rollers 303 are fixedly installed between the two sets of guide plates 301. The guide rollers 303 can fit against the long protective cylinder, further increasing the stability of the long protective cylinder during the lowering process.

[0041] In normal use, the guide hole of the guide plate assembly 301 is slightly larger than the outer diameter of the long protective sleeve, and the side of the long protective sleeve contacts the guide roller 303 and moves downward.

[0042] In one embodiment, the support assembly 1 includes two sets of symmetrically distributed uprights 101, base frames 103, and connecting frames 104.

[0043] The bottom of the upright 101 is fixedly connected to the base frame 103. The base frame 1034 is at a right angle to the upright 101 so that the upright 101 can be stably installed / placed. The support frame 2 is fixedly installed to the side of the upright 101 by bolts. In order to limit the distance between the two sets of uprights 101, a connecting frame 104 is fixedly installed between the two sets of base frames 103. The structure of the support assembly 1 formed in this way is more stable.

[0044] In one embodiment, in order to further increase the connection stability between the upright 101 and the base frame 103, a diagonal brace 102 is connected between the upright 101 and the base frame 103, thereby forming a stable triangular structure.

[0045] In one embodiment, the guide plate assembly 301 includes: two parallel long frames 301a, two parallel short frames 301b, and a plate 301c.

[0046] The short frame 301b is vertically fixed between the two long frames 301a, and the two long frames 301a and the two short frames 301b form a square opening. The top of the two long frames 301a and the two short frames 301b and the position corresponding to the square opening are fixedly connected to the plate 301c. The plate 301c is provided with a guide hole, which is used to guide the long protective cylinder (the long protective cylinder passes through the guide hole during the lowering process).

[0047] The portions of the long frame 301a extending into the short frame 301b on both sides are used to correspond to the support frame 2. For example, the portions of the long frame 301a extending into the short frame 301b on both sides are mounted on the support frame 2 and the two are fixed together using U-bolts.

[0048] In one embodiment, a reinforcing ring 301d is fixedly connected to the edge of the guide hole. The reinforcing ring 301d is used to increase the strength of the edge of the guide hole and prevent the edge of the guide hole from being damaged by impact.

[0049] In one embodiment, the guide roller 303 includes: a connecting portion 303a, a horizontal portion 303b, a roller frame 303c, a guide roller 303d, a guide post 303e, a spring member 303f, and a limiting nut, which are connected between two sets of guide plate groups 301.

[0050] A horizontal part 303b is fixedly provided on one side of the connecting part 303a. Generally, there are two connecting parts 303a, and the horizontal part 303b is located between the two connecting parts 303a. The connecting parts 303a and the horizontal part 303b can be manufactured by an integral molding process. A guide wheel 303d is rotatably installed on the inner side of the roller frame 303c. The guide wheel 303d has a structure that is thin in the middle and thick at both ends, and the edge contour is arc-shaped, so as to better fit with the edge of the long protective cylinder. A guide post 303e is fixedly connected to the outer side of the roller frame 303c. The guide post 303e slides with the through hole opened on the horizontal part 303b. A spring 303f is provided on the guide post 303e and located between the roller frame 303c and the horizontal part 303b. A limiting nut is threaded on the end of the guide post 303e.

[0051] During the lowering of the long casing, there is a skewed movement. This movement will push the guide wheel 303d, roller frame 303c and guide column 303e to slide relative to the horizontal part 303b, compressing the spring component 303f. The resistance provided by the spring component 303f will reduce this skewed movement, making the lowering process of the long casing more stable.
