Description

Technical Field

[0001] The utility model relates to the technical field of pipe pile driving auxiliary equipment, in particular to a pipe pile driving auxiliary guide mechanism which is convenient for adjusting the aperture. Background Art

[0002] During the construction process, when encountering a geological structure with soft soil, the foundation bearing capacity is small and the building is prone to sinking, it is necessary to use a pile driver to pre-drive pipe piles into the soil layer. The side resistance and end resistance of the pipe piles jointly bear the upper load, thereby improving the bearing capacity of the foundation.

[0003] When using a pile driver to drive pipe piles, in order to avoid the problem of the pipe piles tilting during the piling process, a guide device is usually used in conjunction with the pile driver to achieve vertical driving of the pipe piles into the soil layer. However, the existing guide device is difficult to adapt to pipe piles of different diameters during use. When driving pipe piles of different diameters, it is necessary to replace the corresponding guide device, which is inconvenient to use and is not conducive to speeding up the efficiency of piling.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0005] The purpose of the utility model is to provide a pipe pile driving auxiliary guide mechanism that is convenient for adjusting the aperture to solve the technical defects mentioned above. During use, the guide mechanism drives the guide plate to move in the slide groove by starting the driving motor, and the guide plate drives the adjustment clamping plate in the guide tube to move relative to or away from each other through the guide rod, so that the pipe piles of different diameters in the guide tube can be clamped and fixed, thereby improving the practical performance of the mechanism and facilitating the efficiency of pipe pile driving. When the guide plate is moved to clamp and guide the pipe piles with larger diameters, the support rod is synchronously driven to move by the support rod, thereby increasing the support area between the fixed seat and the ground, thereby improving the stability when guiding the pipe piles with larger diameters, and ensuring the verticality between the pipe piles and the ground after piling.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A pipe pile driving auxiliary guide mechanism that is convenient for adjusting the aperture comprises a guide tube, wherein the interior of the guide tube is provided with three groups of adjustment splints in a circular array relative to its axis center line, one side of each of the adjustment splints is fixedly connected with two groups of guide rods slidably connected to the guide tube, the free ends of the two groups of guide rods penetrate the outside of the guide tube and are fixedly connected with a guide plate, a fixing seat is fixedly welded on the outer wall of the guide tube, a movable groove slidably connected to the corresponding guide plate is penetrated on the top of the fixing seat, a screw rod threadedly connected to the corresponding guide plate is rotatably connected in each of the movable grooves, and three groups of support rods are provided at the bottom of the fixing seat relative to the circular array of the guide tube.

[0012] The beneficial effects of the utility model are as follows:

[0013] (1) The utility model provides an auxiliary guide mechanism for pipe pile driving that is convenient for adjusting the aperture. During use, the driving motor is started to drive the driving gear to rotate, and the driving gear drives the corresponding transmission rod to rotate through the transmission gear, and the sprocket, chain and rotating gear drive three sets of screws to rotate synchronously, and the rotating screw drives the corresponding guide plate to move, and the guide plate drives the adjustment clamping plate in the guide tube to move relative to or away from each other through the guide rod, so that pipe piles of different diameters in the guide tube can be clamped and fixed, thereby achieving the guidance of pipe piles of different diameters without replacing the corresponding guide mechanism, thereby improving the practical performance of the mechanism and facilitating the efficiency of pipe pile driving.

[0014] (2) The utility model starts the driving motor to drive the adjusting clamping plates in the guide tube to move away from each other, so as to be suitable for clamping and guiding pipe piles with larger diameters. By connecting the support rod with the guide plate, the support rod is synchronously moved in the direction away from the guide tube, thereby increasing the supporting area between the fixing seat and the ground, thereby improving the stability when guiding the pipe piles with larger diameters and ensuring the verticality between the pipe piles and the ground after piling.

The movable groove 21 is used to install the screw rod 22 and provide a sliding space for the movement of the guide plate 13. A screw rod 22 threadedly connected to the corresponding guide plate 13 is rotatably connected in each movable groove 21, and three groups of support rods 3 are arranged in a circular array at the bottom of the fixing seat 2 relative to the guide tube 1, and the arranged support rods 3 play a role in supporting the fixing seat 2.

[0030] Three groups of driving cavities 23 are provided in a circular array inside the fixed seat 2 relative to the guide tube 1. The driving cavities 23 are used to install transmission rods 24. Each driving cavity 23 is rotatably connected with a transmission rod 24. A transmission gear 25 and a sprocket 29 are installed on the transmission rod 24.
