Description

Technical Field

[0001] This utility model relates to the field of hoisting device technology, and in particular to an auxiliary anti-deviation device for pile foundation hoisting. Background Technology

[0002] Lifting equipment technology refers to the engineering techniques used to lift, move, and position heavy objects using equipment such as cranes and rigging. The main purpose of setting up auxiliary anti-deviation devices is to prevent the heavy object from swinging or shifting during the lifting process due to wind force, inertia, or improper operation, thereby ensuring accurate positioning, improving operational safety, and reducing the risk of collision.

[0003] Under current conditions, a common practice is to use a positioning auxiliary mechanism for lifting devices, such as the one disclosed in announcement number CN221165660U. This mechanism includes a main body of the lifting device, with a load-bearing positioning base at its bottom. Multiple center-of-gravity stabilizing assembly components are stacked on top of each other on the load-bearing positioning base to achieve center-of-gravity stability. However, relying solely on the limiting plate to constrain the counterweight blocks poses a significant safety risk, as lifting vibrations can cause the counterweight blocks to shift or even collapse. Furthermore, the bolted fixing rings are of a fixed size and cannot accommodate lifting rods of different diameters. If the rods are too thin or too thick, the fixing will fail, losing its anti-deviation function. The reliance on manual stacking of the center-of-gravity load-bearing blocks is time-consuming, and the stacked structure is prone to collapse. Utility Model Content

[0004] The purpose of this invention is to solve the problem of the failure of existing technology to automate the positioning of hoisting, and to propose an auxiliary anti-deviation device for pile foundation hoisting.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An auxiliary anti-deviation device for pile foundation hoisting includes a base with positioning rods, on which circumferentially distributed support rods are fixedly installed. A guide plate for guiding the pile foundation is provided on the support rods via a transmission component. A support seat is provided on the support rods for adjusting the hoisting height and for fixing another set of support rods. Four circumferentially distributed positioning blocks extending into a set of support rods located below the support seat are fixedly installed on the support seat. A fastening structure for securing the positioning blocks is provided on the support rods.

[0007] Preferably, the support rod is vertically positioned above the base, and the support base has a ring-shaped structure.

[0008] Preferably, the transmission component includes a fixed frame fixedly mounted on a support rod, and a transmission rod is slidably sleeved on the fixed frame. A movable block is fixedly mounted on the transmission rod, and a spring that cooperates with the transmission rod is welded between the movable block and the fixed frame. A pressure rod extending out of the fixed frame and integrally connected with the guide plate is fixedly mounted on the movable block.

[0009] Hydraulic rods are fixedly installed at both ends of the support rod, and a pressure frame that moves against the transmission rod is fixedly installed at the output end of the hydraulic rod. Guide rods that guide the pressure frame are fixedly installed on both sides of the support rod.

[0010] Preferably, the fixing frame is horizontally positioned at the middle of the support rod, the pressure frame is sleeved on the outer side of the support rod, and the transmission rod and the inner wall of the pressure frame are mutually compatible arc-shaped structures.

[0011] Preferably, the fastening structure includes a limiting frame fixedly installed on one side of the support rod, a limiting rod slidably sleeved on the limiting frame, and a limiting block fixedly installed on the limiting rod. A spring is welded between the limiting block and the limiting frame, and a fastening rod is placed inside the support rod to move against the limiting block and fasten the positioning block.

[0012] Preferably, the fastening rod has a T-shaped structure, and the support rod has a limiting groove for limiting the position of the fastening rod.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. This utility model has a guide plate for guiding the pile foundation through the transmission component. The hydraulic rod drives the pressure frame to move upward, and the transmission rod is pressed through the arc-shaped inner wall, which drives the guide plate to come close to the surface of the pile foundation. This effectively prevents the pile foundation from shifting during hoisting and ensures that the pile foundation is vertical and accurately aligned with the preset position.

[0015] 2. This utility model features a fastening rod that secures the positioning block via a fastening structure, meeting the anti-deviation requirements for hoisting at different heights. When the equipment needs to be raised, the fastening rod is inserted into the corresponding support rod, extended to the designated position, and rotated 90°. The limiting block applies pressure to the fastening rod, ensuring the stability of the fastening rod's fixation to the positioning block. This allows for quick and flexible adjustment of the support rod's height, adapting to diverse hoisting needs. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-6 An auxiliary anti-deviation device for pile foundation hoisting includes a base 1 with positioning rods, and circumferentially distributed support rods 2 fixedly installed on the base 1. The support rods 2 are equipped with guide plates 8 for guiding the pile foundation through transmission components. It should be noted that the inner wall of the guide plate 8 is an arc-shaped structure adapted to the pile foundation, which increases the contact area with the pile foundation, improves the stability of guidance, and effectively prevents deviation during pile foundation hoisting.

[0025] The support rod 2 is provided with a support base 10 for adjusting the hoisting height and for fixing another set of support rods 2. Four positioning blocks 11 are fixedly installed on the support base 10, which are distributed circumferentially and extend into a set of support rods 2 located below it. Through the cooperation of the support base 10 and the positioning blocks 11, the connection of multiple sets of support rods 2 can be realized. The overall height of the device can be flexibly adjusted according to the hoisting needs. The support rod 2 is provided with a fastening structure for fastening the positioning blocks 11. The fastening structure realizes the quick connection between the positioning blocks 11 and the support rod 2, ensuring that the device is stable and reliable after the height is adjusted.

[0026] The support rod 2 is vertically positioned above the base 1. The support base 10 has a ring-shaped structure; please refer to the instruction manual for details. Figure 1 The ring-shaped support 10 provides stable support for the support rod 2, ensuring the stability of the entire structure during operation.

[0027] The transmission component includes a fixed frame 3 fixedly mounted on the support rod 2, and a transmission rod 4 is slidably sleeved on the fixed frame 3. A movable block 5 is fixedly mounted on the transmission rod 4, and a spring 6 that cooperates with the transmission rod 4 is welded between the movable block 5 and the fixed frame 3. A pressure rod 7 that extends out of the fixed frame 3 and is integrally connected with the guide plate 8 is fixedly mounted on the movable block 5.

[0028] Hydraulic rods are fixedly installed at both ends of the support rod 2, and a pressure frame 9 that moves against the transmission rod 4 is fixedly installed at the output end of the hydraulic rod. Guide rods that guide the pressure frame 9 are fixedly installed on both sides of the support rod 2. For details, please refer to the appendix of the instruction manual. Figure 3 When the hydraulic rod is activated, it drives the pressure frame 9 to move along the guide rod. The pressure frame 9 applies a force to the transmission rod 4, causing the transmission rod 4 to slide within the fixed frame 3. This, in turn, drives the guide plate 8 to move via the moving block 5 and the pressure rod 7. When the force of the pressure frame 9 disappears, the spring 6 drives the transmission rod 4 and other components to reset for the next adjustment.

[0029] The fixing frame 3 is horizontally positioned at the middle of the support rod 2, and the pressure applying frame 9 is sleeved on the outside of the support rod 2. The transmission rod 4 and the inner wall of the pressure applying frame 9 have mutually adaptable arc-shaped structures. Please refer to the appendix of the instruction manual for details. Figure 3 The arc-shaped structure allows for a smoother force transmission between the transmission rod 4 and the pressure frame 9, preventing jamming and ensuring that the guide plate 8 can smoothly approach or move away from the pile foundation.

[0030] The fastening structure includes a limiting frame 12 fixedly installed on one side of the support rod 2, a limiting rod 13 slidably sleeved on the limiting frame 12, and a limiting block 14 fixedly installed on the limiting rod 13. A spring 15 is welded between the limiting block 14 and the limiting frame 12. A fastening rod 16 is placed inside the support rod 2, which moves against the limiting block 14 and fastens the positioning block 11. For details, please refer to the appendix of the instruction manual. Figure 5 When it is necessary to tighten the positioning block 11, the fastening rod 16 is placed into the support rod 2 and rotated 90°. Under the action of the spring 15, the limiting block 14 applies pressure to the fastening rod 16, so that the fastening rod 16 is tightly inserted into the limiting groove, thereby fixing the positioning block 11. The limiting rod 13 guides the movement of the limiting block 14, ensuring the accuracy of its pressure direction.

[0031] The fastening rod 16 has a T-shaped structure, and the support rod 2 has a limiting groove inside to limit the movement of the fastening rod 16. Please refer to the instruction manual for details. Figure 6 The end of the T-shaped fastening rod 16 is inserted into the limiting groove to ensure a stable connection with the positioning block 11. The limiting groove restricts the range of movement of the fastening rod 16, preventing it from shifting during operation and further ensuring the stability of the positioning block 11.

[0032] It should be noted that the specific model and specifications of the hydraulic rod need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts existing technology in this field, so it will not be elaborated here.

[0033] The functional principle of this utility model can be explained through the following operation methods:

[0034] When a relatively high pile foundation height needs to be hoisted;

[0035] Place the positioning block 11 on the support base 10 into the support rod 2, insert the positioning block 11 into the support rod 2, rotate 90° so that the fastening rod 16 is inserted into the limiting groove, and the spring 15 pushes the limiting block 14 to press against the fastening rod 16, so that the fastening rod 16 fastens the positioning block 11. According to the required hoisting height, install the corresponding number of support bases 10 on the support rod 2 to complete the adjustment of the guide plate 8 to assist in the anti-deviation height.

[0036] The hydraulic rod output end drives the pressure frame 9 to move along the guide rod. The pressure frame 9 applies pressure to the transmission rod 4 through the arc-shaped inner wall. The transmission rod 4 pushes the moving block 5 to compress the spring 6. The moving block 5 drives the pressure rod 7 to push the guide plate 8 towards the pile foundation until the guide plate 8 is close to the pile foundation surface.

[0037] During the pile foundation hoisting process, the guide plate 8 plays a guiding and limiting role for the pile foundation, realizing the auxiliary anti-deviation function for the pile foundation hoisting.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
