Description

Technical Field

[0001] The utility model relates to the technical field of coastal soft foundation treatment, in particular to a plastic drainage board pile driver latch. Background Art

[0002] The plastic drain board pile driver, also known as the plastic drain board plug-in machine, is a new type of piling machinery used in coastal soft foundation treatment, land reclamation and other construction fields. The pile driver sinks into the insertion position, and the plastic drain board passes through the casing and is connected to the anchor shoe at the end. Then, the casing supports the anchor shoe and inserts the plastic drain board to the designed depth of soil. After pulling up the casing, the anchor shoe remains in the soil together with the drain board, and then the continuous plastic drain board is cut off, completing a drainage hole plug-in operation.

[0003] However, the existing pile drivers still have certain defects in actual use: the existing pile drivers have a high back-draft rate, and are usually adjusted by deepening the plug plate, or leaving the pile mouth and the drainage board in the soil. This method increases the difficulty of construction and quality control. Based on the existing technical deficiencies, the utility model designs a plastic drainage board pile driver pin. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a plastic drain board pile driver pin, which has the advantage of reducing the back-carrying phenomenon of the plastic drain board.

[0005] The utility model provides the following technical solutions: a plastic drainage board pile driver pin, which is installed on a conduit, a driving structure is installed on the top of the conduit, and a pin structure is installed on the inner wall of the conduit; the pin structure includes two inner tubes, pull rods are movably installed inside the two inner tubes, connecting plates are installed on the tops of the two pull rods, U-shaped rods are installed at one end of the bottom of the two pull rods, a connecting rod is installed at the bottom of the U-shaped rod, and a spherical pin is installed at the bottom of the connecting rod; the driving structure includes a fixed bracket, an electric cylinder is installed inside the fixed bracket, and one end of the telescopic rod of the electric cylinder is fixedly connected to the connecting plate.

[0006] As a preferred technical solution of the utility model, a top plate is installed between the two inner tubes, a spring is installed at the bottom of the top plate, and the spring is fixedly connected to the U-shaped rod.

[0007] As a preferred technical solution of the utility model, the length of the conduit can be selected according to the required construction depth, and the lengths of the two inner tubes and the two pulling rods are selected according to the length of the conduit.

[0008] As a preferred technical solution of the utility model, the setting direction of the pin structure is perpendicular to the penetration direction of the drain board body, and the setting direction of the drive structure is perpendicular to the penetration direction of the drain board body.

[0009] As a preferred technical solution of the present utility model, a drainage plate main body is placed inside the conduit, and one end of the bottom of the drainage plate main body passes through the bottom of the spherical pin.

[0010] As a preferred technical solution of the present utility model, a tapered pipe is provided at the bottom of the conduit, and the tapered pipe is communicated with the conduit.

[0011] As a preferred technical solution of the present utility model, an empty groove is opened at the bottom of the tapered pipe, and the size of the empty groove is 2 cm larger than that of the spherical pin.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] 1. For the pin of the plastic drainage plate driving machine of the present utility model, when laying the drainage plate main body through the driving structure and the pin structure, by passing one end of the bottom of the drainage plate main body through below the spherical pin, at this time, through the drive of the electric cylinder, its telescopic rod drives the connecting plate to squeeze the two pulling rods downward. At this time, the spring stretches, driving the spherical pin to catch the empty groove. At this time, the drainage plate main body is fixed. Then, the conduit is sent into the soil layer by the driving machine. After the drainage plate main body is sent to the soil layer, by starting the fixed bracket to continuously expand and contract, the spherical pin continuously hammers the drainage plate main body to make its connection with the soil layer closer. Then, when the conduit moves upward, the spherical pin does not contact the drainage plate main body, thus avoiding the occurrence of the backhaul phenomenon;

[0014] 2. For the pin of the plastic drainage plate driving machine of the present utility model, through the setting of the tapered pipe, from the traditional circular cross-section, the front end is changed to a tapered cross-section, which can not only increase the soil cutting ability during the driving process of the pile, but also increase the pressure during the lifting process, so that the drainage plate main body can effectively break away from the pile nozzle and reduce the backhaul phenomenon of the drainage plate main body.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-5 , a plastic drainage board driving pile inserting pin, which is installed on the conduit 1. A driving structure 5 is installed at the top of the conduit 1, and a pin structure 6 is installed on the inner wall of the conduit 1; the pin structure 6 includes two inner tubes 61. A pulling rod 62 is movably installed inside the two inner tubes 61. A connecting plate 63 is installed at the top of the two pulling rods 62. One end of the bottom of the two pulling rods 62 is installed with a U-shaped rod 64. A connecting rod 65 is installed at the bottom of the U-shaped rod 64. A ball pin 66 is installed at the bottom of the connecting rod 65; the driving structure 5 includes a fixed bracket 51. An electric cylinder 52 is installed inside the fixed bracket 51. One end of the telescopic rod of the electric cylinder 52 is fixedly connected to the connecting plate 63.

[0023] Please refer to Figure 5 , a top plate 67 is installed between the two inner tubes 61. A spring 68 is installed at the bottom of the top plate 67. The spring 68 is fixedly connected to the U-shaped rod 64.

[0024] The connection strength between the U-shaped rod 64 and the top plate 67 can be strengthened through the spring 68, and at the same time, the impact generated by the expansion and contraction of the ball pin 66 can be buffered.

[0025] Please refer to Figure 1 Figure 2 and Figure 5 , the length of the conduit 1 can be selected according to the depth required for construction, and the lengths of the two inner tubes 61 and the two pulling rods 62 are selected according to the length of the conduit 1. The setting direction of the pin structure 6 is perpendicular to the penetration direction of the drainage board body 3, and the setting direction of the driving structure 5 is perpendicular to the penetration direction of the drainage board body 3. The drainage board body 3 is placed inside the conduit 1, and one end of the bottom of the drainage board body 3 passes through the bottom of the ball pin 66.

[0026] The two inner tubes 61 are fixed to the inner wall of the conduit 1 by welding, and the connecting rod 65 is threadedly connected to the U-shaped rod 64.

[0027] Please refer toFigures 1-3 , a conical pipe 2 is provided at the bottom of the conduit 1, and the conical pipe 2 is communicated with the conduit 1. An empty groove 4 is opened at the bottom of the conical pipe 2, and the size of the empty groove 4 is 2 cm larger than that of the spherical pin 66.

[0028] Changing the traditional circular cross-section of the conical pipe 2 to a conical cross-section can not only increase the soil cutting ability during the pile driving and sinking process, but also increase the pressure during the lifting process, so that the main body 3 of the drainage plate can be effectively separated from the pile nozzle, reducing the phenomenon of the main body 3 of the drainage plate being pulled back.

[0029] Working principle: When a plastic drainage plate pile driver is used as a plug, in the initial state, first move the pile driver to the construction area. Insert one end of the main body 3 of the drainage plate into the top of the conduit 1 and pass the bottom end thereof through below the spherical pin 66. Then start the electric cylinder 52 so that its telescopic rod drives the connecting plate 63 to squeeze the two pulling rods 62 downward. At this time, the spring 68 is stretched, driving the spherical pin 66 to catch the empty groove 4. At this time, the main body 3 of the drainage plate is fixed. By starting the pile driver, the conduit 1 is sent to the soil layer. After reaching the predetermined soil layer, start the fixed bracket 51 to make it continuously expand and contract, so that the spherical pin 66 continuously hammers the main body 3 of the drainage plate to make its connection with the soil layer closer. Subsequently, when the conduit 1 moves upward, the spherical pin 66 does not contact the main body 3 of the drainage plate, which can avoid the occurrence of the pulling-back phenomenon. At the same time, changing the traditional circular cross-section of the conical pipe 2 to a conical cross-section can not only increase the soil cutting ability during the pile driving and sinking process, but also increase the pressure during the lifting process, so that the main body 3 of the drainage plate can be effectively separated from the pile nozzle, reducing the phenomenon of the main body 3 of the drainage plate being pulled back.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
