Description

Technical Field

[0001] The utility model relates to the field of pipe pile related products, in particular to a pile tip structure of a pipe pile. Background Art

[0002] The pile tip is used in prestressed concrete pile foundation construction. It's the front end of the pile and is installed on the pile head during sinking, serving as a guide and plug. During precast pile construction, the pile tip is typically welded to the pile head, guiding the pile body into the soil to prevent damage to the pile head and prevent the pile body from tilting (for verticality control), allowing for better penetration into the bearing stratum.

[0003] During the installation of the existing prestressed pipe pile tip, it is necessary to manually rotate the position of the pipe pile tip on the pipe pile body to ensure that the connection groove of the pipe pile tip coincides with the threaded hole on the pipe pile body, and then perform threaded connection processing through connecting bolts. The above operation method cannot achieve the rapid installation processing of the pipe pile tip, thereby affecting the assembly processing of the pipe pile tip. Utility Model Content

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," "the other end," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc. should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0020] See also Figure 1-3 The utility model provides an embodiment of a pile tip structure of a pipe pile, including a pipe pile 1 and a pile tip 2, a mounting sleeve 3 is fixedly sleeved on the pile tip 2, a positioning sleeve 4 is fixedly sleeved on the pipe pile 1, and the bottom of the mounting sleeve 3 is fixedly connected with two symmetrically arranged positioning plates 5, and the positioning sleeve 4 is provided with a slot corresponding to the positioning plate 5, and the positioning plate 5 is slidably inserted in the slot, and the positioning sleeve 4 is fixedly connected to a bracket 6 on the outer wall of the slot, and a sliding rod 7 is slidably inserted on the bracket 6, and the bottom end of the sliding rod 7 is fixedly connected to a wedge plate 8, and the outer wall of the positioning plate 5 is provided with a slot corresponding to the wedge plate 8, When the locking bolt 13 is screwed into the screw hole on the stop block 11, the sliding rod 7 is fixed.

[0021] In this embodiment, the bottom of the pile tip 2 is fixedly connected to a symmetrically arranged alignment plate 14, and the pipe pile 1 is provided with an alignment groove corresponding to the alignment plate 14, which is assembled and aligned during installation to avoid misalignment; the elastic member 10 is a spring with high gain; the locking bolt 13 is a hexagonal bolt; one side of the wedge plate 8 is provided with an inclined section, which is a polished surface to reduce the pressure resistance; the two ends of the bracket 6 are bent to reserve space for the wedge plate 8.

[0022] Working principle: First, the pile tip 2 and the pipe pile 1 are docked and assembled. At this time, the positioning plate 5 on the installation sleeve 3 will be inserted into the slot on the positioning sleeve 4. At the same time, the positioning plate 5 will press the wedge plate 8. Due to the structural characteristics of the wedge plate 8, the slide rod 7 can slide on the bracket 6. At the same time as the slide rod 7 slides, the anti-slip block 9 installed thereon will press the elastic member 10 to compress it. When the slot on the positioning plate 5 corresponds to the position of the wedge plate 8, the elastic member 10 in the compressed state pushes the anti-slip block 9 under the action of its own rebound force, thereby prompting the slide rod 7 to push the wedge plate 8 to be clamped in the slot on the positioning plate 5 to achieve fixation between the positioning plate 5 and the positioning sleeve 4, and then achieve fixation between the pile tip 2 and the pipe pile 1, and then screw the locking bolt 13 into the screw hole on the stop block 11 to fix the slide rod 7.

[0023] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
