[0036] Based on the content mentioned above, at present, welding is usually used to connect two prestressed pipe piles. Specifically, steel plates are provided at both ends of the prestressed pipe piles, and then the steel plates at both ends of the two prestressed pipe piles are welded into one. However, the welding method is prone to cold welding and leaking welding, which leads to poor connection strength and life.

[0037] To solve the above problems, please refer to Figures 1 to 3 The present embodiment provides a prestressed pipe pile 100 connector, which is used to connect two prestressed pipe piles 100 into one. The prestressed pipe pile 100 connector includes a first end plate 1, a second end plate 2, a connector 3, a connecting hole 4, a plurality of elastic universal balls 5, an annular clamping groove 6 and a fixing assembly 7.

[0038] The first end plate 1 and the second end plate 2 are respectively arranged at the two ends of the prestressed pipe pile 100. The connector 3 is detachably arranged on the first end plate 1. The connecting hole 4 is arranged on the second end plate, and the connector 3 can be adapted and snap-fitted with the connecting hole 4. In the present embodiment, the connector 3 can be screwed on the first end plate 1, and the connector 3 is located at the center of the first end plate 1. It can be understood that the way in which the connector 3 is screwed to the first end plate 1 is more convenient for assembling the connector 3, and the connection is reliable. Of course, in other embodiments, an assembly hole adapted to the connector 3 can also be arranged on the first end plate 1, and the connector 3 can be inserted into the assembly hole after the adhesive is filled in the assembly hole, which will not be described in detail.

[0039] In order to facilitate the insertion of the connecting member 3 into the connecting hole 4, the end of the connecting member 3 is configured to be tapered.

[0040] A plurality of elastic universal balls 5 are arranged on the connecting member 3, and the plurality of elastic universal balls 5 are evenly distributed on the peripheral side of the connecting member 3. In the present embodiment, 8 elastic universal balls 5 are arranged. Of course, in other embodiments, the elastic universal balls 5 can be arranged to be 6, 4 or other numbers. It should be noted that the elastic universal balls 5 are prior art, and the specific model can be selected according to the actual application scenario. The present embodiment does not make specific requirements and restrictions on this. An annular snap-fit ​​groove 6 is arranged on the inner wall of the connecting hole 4, and a plurality of elastic universal balls 5 can all fall into the annular snap-fit ​​groove 6 and snap-fit ​​with the annular snap-fit ​​groove 6. The fixing assembly 7 is arranged between the first end plate 1 and the second end plate 2, and is configured to fix the first end plate 1 and the second end plate 2 together.

[0041] In practical applications, the connecting piece 3 on one prestressed pipe pile 100 is first aligned with the connecting hole 4 on the other prestressed pipe pile 100, and then the connecting piece 3 on one prestressed pipe pile 100 is gradually inserted into the connecting hole 4 on the other prestressed pipe pile 100 until a plurality of elastic universal balls 5 on the connecting piece 3 fall into the annular clamping groove 6, thereby realizing the connection of the two prestressed pipe piles 100, and finally the first end plate 1 and the second end plate 2 are fixed together by the fixing assembly 7, thereby completing the connection of the two prestressed pipe piles 100.

[0042] It can be understood that the above-mentioned prestressed pipe pile 100 connecting head realizes the connection of two prestressed pipe piles 100 by mechanical connection, which can avoid the problem of poor connection strength and life due to cold welding, leaking welding and other reasons in the welding connection method, thereby improving the reliability of the connection between the two prestressed pipe piles 100, and can also reduce the labor intensity of workers and improve construction efficiency.

[0043] It can also be understood that by fixing the first end plate 1 and the second end plate 2 together through the fixing assembly 7, the first end plate 1 and the second end plate 2 can be more firmly fitted. Specifically, the fixing assembly 7 includes a first fixing portion 71, a second fixing portion 72, a clamp 73 and a limiter (not shown in the figure).

[0044] The prestressed pipe pile 100 is extended in an annular shape from the outer side of the first end plate 1 to form a first fixing portion 71. The prestressed pipe pile 100 is extended in an annular shape from the outer side of the second end plate 2 to form a second fixing portion 72. The first fixing portion 71 and the second fixing portion 72 can fit together to form a fixing member. It should be noted that the first fixing portion 71 is also the outermost part of the first end plate 1, and the two are integrally formed, with high structural strength. Similarly, the second fixing portion 72 is integrally formed with the second end plate 2.

[0045] The clamp 73 includes an annular fixing groove, and the clamp 73 can be clamped on the outer periphery of the fixing member, so that the fixing member and the fixing groove are adapted and snap-fitted. The limiter is configured to lock the clamp 73 on the fixing member. In this way, the two prestressed pipe piles 100 can be fixed together in the axial direction of the prestressed pipe piles 100, that is, the axial movement of the two prestressed pipe piles 100 during the construction process can be avoided, so that the connection of the two prestressed pipe piles 100 can be made more reliable.

[0046] It is understandable that the method of fixing the first fixing part 71 and the second fixing part 72 with the clamp 73 has a simple structure and is easy to operate. In this embodiment, the limiter includes a bolt and a nut, and the bolt can pass through the head and tail ends of the clamp 73 and be screwed with the nut. It is understandable that the screw connection method is easy to operate and the connection is reliable. Of course, in other embodiments, the limiter can also adopt a connecting structure composed of a clamping block and a clamping groove, which is not described in detail in this embodiment. In order to improve the convenience of matching the clamp 73 and the fixing member, the notches on both sides of the annular fixing groove are chamfered to form a guide surface 731. Such a configuration makes it easier to buckle the annular fixing groove on the fixing member for easy operation.

[0047] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
