Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0024] The following is a reference to the appendix. Figure 1 This invention describes an auxiliary device for adjusting the gap between steel piles in a guide frame.

[0025] like Figure 1 As shown, the auxiliary device for adjusting the gap between the steel pile and the guide frame in this utility model is used to adjust the gap between the steel pile and the guide frame. It includes a first connecting plate 1 and a second connecting plate 2. The second connecting plate 2 is connected to one end of the first connecting plate 1. The first connecting plate 1 is provided with a locking structure 3. The first connecting plate 1 abuts against the guide frame. Rotating the locking structure 3 allows the first connecting plate 1 to be engaged with the guide frame through the cooperation of the second connecting plate 2 and the locking structure 3. A hydraulic jack is connected to the side of the first connecting plate 1 away from the locking structure 3 through a snap-fit ​​structure 4. One end of the hydraulic jack abuts against the fixing plate 5 of the first connecting plate 1, and the end of the hydraulic jack away from the fixing plate 5 abuts against the steel pile, so that the hydraulic jack can move the steel pile.

[0026] The hydraulic jack can be fixed to the first connecting plate 1 by the snap-fit ​​structure 4 to prevent it from falling off and ensure the safety of personnel and equipment. The locking structure 3 is used to fix it to the upper edge of the guide frame, which can meet the needs of different thicknesses. This application eliminates the need for extensive welding required for adjusting the gap in traditional methods, reduces the labor intensity of operators, improves construction progress, and saves production costs.

[0027] Furthermore, such as Figure 1As shown, the locking structure 3 includes a locking nut 31 and a locking bolt 32. The locking bolt 32 is rotatably connected to the locking nut 31, and the locking nut 31 is connected to the first connecting plate 1. The screw position of the locking bolt 32 is adjusted so that the first connecting plate 1 is snapped onto the guide frame. The first connecting plate 1 includes a main connecting plate 11 and a secondary connecting plate 12. The secondary connecting plate 12 is fixedly connected to the end of the main connecting plate 11 away from the second connecting plate 2. The main connecting plate 11 is fixedly connected to the locking nut 31 through the upright plate 6. The secondary connecting plate 12 is fixedly connected to the main connecting plate 11 so that the first connecting plate 1 is arranged in an L-shape.

[0028] In this embodiment, preferably, the locking structure 3 consists of a locking nut 31 and a locking bolt 32. The locking nut 31 is vertically connected to the first connecting plate 1, and the locking bolt 32 is screwed onto the locking nut 31. The screwing position of the locking bolt 32 is adjusted, that is, the locking bolt 32 moves along the length direction of the first connecting plate 1 so that the locking bolt 32 abuts against the outer wall of the guide frame, and the second connecting plate 2 connected to the first connecting plate 1 abuts against the inner wall of the guide frame, thereby making the first connecting plate 1 snapped onto the guide frame.

[0029] By engaging the locking bolt 32 with the second connecting plate 2, the first connecting plate 1 can be snapped onto the guide frame of different thicknesses, avoiding welding operations and saving production costs.

[0030] In a preferred embodiment, the first connecting plate 1 is composed of a main connecting plate 11 and a secondary connecting plate 12. The secondary connecting plate 12 is vertically welded to one end of the main connecting plate 11, and a second connecting plate 2 is vertically welded to the end of the main connecting plate 11 away from the secondary connecting plate 12, so that the whole is arranged in a Z-shape on the guide frame.

[0031] A vertical plate 6 is welded onto the main connecting plate 11. The locking nut 31 is fixedly connected to the main connecting plate 11 through the vertical plate 6, thereby allowing the locking bolt 32 to adjust the screw length along the length direction of the main connecting plate 11.

[0032] Furthermore, such as Figure 1 As shown, the main connecting plate 11 has a snap-fit ​​structure 4 at the end away from the vertical plate 6, so that the hydraulic jack is snapped onto the main connecting plate 11 along the length direction of the main connecting plate 11; the snap-fit ​​structure 4 includes a first arc plate assembly 41 and a second arc plate assembly 42, and the hydraulic jack is snapped onto the main connecting plate 11 through the first arc plate assembly 41 and the second arc plate assembly 42; the first arc plate assembly 41 and the second arc plate assembly 42 are connected to the main connecting plate 11 at intervals.

[0033] In this embodiment, a first arc plate assembly 41 and a second arc plate assembly 42 are spaced apart on the main connecting plate 11 for fixing the hydraulic jack. Preferably, the first arc plate assembly 41 and the second arc plate assembly 42 are both located on the side of the main connecting plate 11 away from the vertical plate 6, and the hydraulic jack is clamped and fixed along the length direction of the main connecting plate 11 by the spaced first arc plate assembly 41 and the second arc plate assembly 42.

[0034] Furthermore, such as Figure 1 As shown, a fixing plate 5 is connected to the auxiliary connecting plate 12. The fixing plate 5 abuts against one end of the hydraulic jack so that the hydraulic jack moves the steel pile away from the fixing plate 5. A handle 7 is connected to the side of the auxiliary connecting plate 12 away from the fixing plate 5. The first arc plate assembly 41 and the second arc plate assembly 42 are both composed of two arc plates to lock and fix the hydraulic jack.

[0035] In this embodiment, preferably, a fixing plate 5 is welded onto the auxiliary connecting plate 12, and the hydraulic jack abuts against the fixing plate 5 to increase the force-bearing area of ​​the hydraulic jack; the end of the hydraulic jack away from the fixing plate 5 abuts against the steel pile, and the hydraulic jack is activated to adjust the gap between the steel pile and the guide frame.

[0036] A handle 7 is welded on the side of the secondary connecting plate 12 away from the fixed plate 5, allowing construction workers to easily adjust the position of the device by gripping the handle 7.

[0037] In a preferred embodiment, the first arc plate assembly 41 and the second arc plate assembly 42 are the same in shape and size, and each is composed of two symmetrically arranged arc plates. The first arc plate assembly 41 and the second arc plate assembly 42 match the shape of the hydraulic jack, thereby allowing the hydraulic jack to be snapped and fixed on the main connecting plate 11.

[0038] The steel pile is inserted vertically into the opening of the jacket. A connecting plate structure is provided along the opening of the jacket, i.e., the upper edge, so that the locking bolt 32 and the second connecting plate 2 are engaged with the connecting plate structure of the jacket. Pressure is applied to the steel pile by a hydraulic jack to change the vertical gap between the steel pile and the jacket.

[0039] The working principle of the auxiliary device for adjusting the gap between the guide frame steel piles in this utility model is as follows:

[0040] First, the construction workers place the device on the guide frame using the handle 7, with the locking bolt 32 and the second connecting plate 2 located on both sides of the guide frame;

[0041] Then, adjust the locking bolt 32 so that the first connecting plate 1 is snapped onto the guide frame;

[0042] Then, the hydraulic jack is snapped onto the first connecting plate 1 through the first arc plate assembly 41 and the second arc plate assembly 42, with one end of the hydraulic jack abutting against the fixed plate 5, and the telescopic end of the hydraulic jack away from the fixed plate 5 facing the steel pile.

[0043] Finally, the hydraulic jacks are activated, and pressure is applied to the steel piles through their extension ends to adjust the gap between the steel piles and the guide frame.

[0044] Based on the auxiliary device for adjusting the gap between steel piles of the guide frame, this utility model uses a first arc plate assembly 41 and a second arc plate assembly 42 to fix the hydraulic jack on the first connecting plate 1, preventing the hydraulic jack from falling off and ensuring the safety of personnel and equipment. A locking structure 3 is used to fix it to the upper edge of the guide frame, which can meet the needs of different thicknesses. This application eliminates the need for extensive welding required by traditional methods of gap adjustment, reduces the labor intensity of workers, improves construction progress, and saves production costs.
