Description

Technical Field

[0001] The utility model belongs to the technical field of pile driver fixing, and more specifically, particularly relates to a fixing device for a pile driver base on a construction platform. Background Technique

[0002] A pile driver consists of a pile hammer, a pile frame and auxiliary equipment, etc. The pile hammer is attached between two parallel vertical guide rods at the front of the pile frame and is lifted by a lifting hook. The pile frame is a steel structure tower, and a winch is provided at its rear for lifting the pile and the pile hammer. There is a guide frame composed of two guide rods in front of the pile frame to control the driving direction of the pile and make the pile accurately penetrate into the formation according to the designed orientation. The basic technical parameters of the pile driver are the weight of the impact part, the impact kinetic energy and the impact frequency.

[0003] The pile driver is usually equipped with a base, and the pile driver generally works by being placed on the soil surface. In order to ensure the stability of the pile driver during work, it is necessary to fix the base of the pile driver, so a fixing device for the pile driver base is required to fix the pile driver.

[0004] Based on the above, the inventor found the following problems: The existing fixing devices for pile driver bases are usually simply knocked into the soil and then used to fix the base. However, when the pile driver is working, strong vibrations will occur, causing the part of the fixing device connected to the soil to separate, resulting in insufficiently tight fixing of the base.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a fixing device for a pile driver base on a construction platform is provided, with the expectation of achieving a more practical value. Content of the Utility Model

[0027] As attached Figure 1 To Attachment Figure 4 As shown:

[0028] The utility model provides a fixing device for a pile driver base on a construction platform, comprising a main rod 1, a soil-breaking rod 2 is fixed to the bottom end of the main rod 1, a support plate 3 is fixed to the outer wall of the main rod 1, a first handle 5 is fixed to the top of the outer wall of the main rod 1, a connecting disk 8 is detachably connected to the top of the main rod 1, a connecting rod 10 is rotatably connected to the top of the connecting disk 8, a threaded rod 11 is threadedly connected to the top of one end of the connecting rod 10 away from the connecting disk 8, a bearing 13 is rotatably connected to the bottom end of the threaded rod 11, an extrusion seat 14 is fixed to the bottom of the bearing 13, and a second handle 12 is fixed to the top of the outer wall of the threaded rod 11.

[0029] Among them, the ground-breaking rod 2 is arranged in a cone shape, a tip 4 is opened at one end of the bottom of the support plate 3, the support plate 3 is arranged in a spiral shape, and the support plate 3 and the main rod 1 are arranged in an inclined shape. The conical ground-breaking rod 2 can better insert the main rod 1 into the soil, and when the main rod 1 is rotated, the support plate 3 spirally rotates downward, driving the main rod 1 into the soil. The inclined support plate 3 allows the soil to better support the main rod 1 and prevent the main rod 1 from moving upward.

[0030] Among them, there are multiple first handles 5, and the multiple first handles 5 are arranged at equal intervals in a circumferential shape. The multiple first handles 5 can be rotated manually, and the main rod 1 can be rotated by a motor equipped with a special connector to quickly place the multiple main rods 1 around the pile driver base to be installed.

[0031] Among them, a connecting sleeve 7 is fixed to the bottom of the connecting plate 8, and a connecting seat 6 is fixed to the top of the main rod 1. The connecting sleeve 7 and the connecting seat 6 are movably sleeved. A first limiting hole 61 is penetrated through one side of the connecting seat 6, and a second limiting hole 71 is penetrated through one side of the connecting sleeve 7. There are multiple first limiting holes 61 and multiple second limiting holes 71. A limiting bolt 9 penetrates through the inside of the first limiting hole 61, and a fastening nut 91 is threadedly connected to the outside of one end of the limiting bolt 9. When installing the main rod 1, remove the connecting plate 8, separate the connecting sleeve 7 from the connecting seat 6, directly install the main rod 1, and then connect the connecting sleeve 7 to the connecting seat 6 after the installation of the main rod 1 is completed. After the connection is completed, use multiple limiting bolts 9 to pass through the second limiting hole 71 and the first limiting hole 61, and then tighten the fastening nut 91.

[0032] Among them, there are two connecting rods 10, and the two connecting rods 10 are fixedly connected vertically, and adjacent ends of the two connecting rods 10 are both fixed to the top of the connecting plate 8, so that one main rod 1 corresponds to two connecting rods 10.

[0033] Among them, a groove 141 is opened at the bottom of the extrusion seat 14, and there are multiple grooves 141, and the multiple grooves 141 are arranged at equal intervals horizontally. By rotating the second handle 12 to drive the threaded rod 11 to rotate, the extrusion seat 14 moves downward, and the top of the pile driver base is extruded by the extrusion seat 14 to limit it. The provided groove 141 increases the friction between the extrusion seat 14 and the pile driver base to prevent the extrusion seat 14 from sliding.

[0034] Among them, the length value of the threaded rod 11 is greater than the horizontal height difference between the bottom of the connecting rod 10 and the top of the support plate 3, so that after the main rod 1 completely enters the soil, the threaded rod 11 moves to a lower position, which is suitable for fixing pile driver bases of various thicknesses.

[0035] The specific usage method and function of this embodiment:

[0036] In the present invention, firstly, the connecting plate 8 is removed, the connecting sleeve 7 is separated from the connecting seat 6, and the main rod 1 is directly installed. A plurality of main rods 1 are placed around the base of the pile driver to be installed. A plurality of first handles 5 are provided to manually rotate the main rod 1 or to rotate the main rod 1 through a motor equipped with a special connecting head. The plurality of main rods 1 can be installed quickly. The conical breaking rod 2 can better insert the main rod 1 into the soil. When the main rod 1 is rotated, the supporting plate 3 spirally rotates downward, driving the main rod 1 into the soil. The inclined supporting plate 3 allows the soil to better support the main rod 1, preventing the main rod 1 from moving upward. After the rod 1 is installed, the connecting sleeve 7 is connected to the connecting seat 6. After the connection is completed, multiple limit bolts 9 are used to pass through the second limit hole 71 and the first limit hole 61, and then the fastening nut 91 is tightened. Finally, the second handle 12 is turned to drive the threaded rod 11 to rotate, so that the extrusion seat 14 moves downward, and the top of the pile driver base is squeezed by the extrusion seat 14 to limit it. The groove 141 provided increases the friction between the extrusion seat 14 and the pile driver base to prevent the extrusion seat 14 from sliding. One main rod 1 corresponds to two connecting rods 10. When fixing the base, the two connecting rods 10 can be fixed parallel to one side of the pile driver base.
