Technical Field
[0001] The utility model relates to the technical field of industrial machinery, in particular to a universal joint structure for pile pulling. Background Art
[0002] The universal joint structure for pile pulling is usually a device for connecting the upper section pile and the lower section pile, which can adapt to pile pulling operations at different angles and ensure the strength and stability of the connection. Specifically, this structure usually includes the following parts: flange: a first flange is fixed at the bottom end of the upper section pile, and a second flange is fixed at the top end of the lower section pile. The function of the flange is to provide a connection surface between the connection joint and the pile body. Connector: the connector is composed of two connecting rings, and the ends of the two connecting rings are fixed together by welding or other methods. Side wall and cone: the side of the connecting ring is provided with a first side wall and a second side wall extending radially inward, and a cone located between the two. These structures are combined to form a limiting cavity to accommodate the flange and ensure the stability of the connection. Inclined surface: the relative plane of the first flange and the second flange is designed as an inclined surface that is against the side of the cone, which can increase the tightness of the contact surface, thereby improving the sealing and pull-out resistance of the connection. In actual engineering applications, the design of this universal joint structure is intended to simplify the connection method of the pull-out-resistant pipe piles, improve construction efficiency, and at the same time ensure good pull-out bearing capacity and stability of the connection.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] like Figures 1 to 4 As shown, this embodiment provides a technical solution, a universal joint structure for pile pulling, including a universal bead 1, and a transmission assembly 2 is connected to the universal bead 1;
[0029] The transmission assembly 2 includes a first sliding column 23, on which a first sliding frame 21 and a second sliding frame 22 are movably connected, and a rotating drum 3 is fixedly connected to the first sliding frame 21 and the second sliding frame 22 on one side away from the first sliding column 23, and a connecting plate 4 is fixedly connected to the rotating drum 3 on one side away from the first sliding frame 21 and the second sliding frame 22.
[0030] By setting a universal ball 1 and a transmission assembly 2 connected thereto, the transmission assembly 2 is composed of a first sliding column 23, a first sliding frame 21 and a second sliding frame 22, all of which are connected to a rotating drum 3, and a connecting plate 4 is fixedly connected to one end of the rotating drum 3 away from the sliding frame, and a connecting frame 41 is fixedly connected to the side of the connecting plate 4 away from the rotating drum 3. In addition, an extension plate 42 is fixedly connected to the connecting frame 41 to facilitate the connection of a pneumatic telescopic rod 43, which simplifies the connection method of the anti-pulling pipe pile, improves the construction efficiency, ensures good anti-pulling bearing capacity and stability of the connection, and can more effectively adapt to pile pulling operations at different angles.
[0031] Further, such as Figures 1 to 4 As shown, a connection frame 41 is fixedly connected to one side of the connection plate 4 away from the rotating drum 3. By providing the connection frame 41, when the universal connection structure is subjected to pressure, the pressure will be transmitted to the bottom of the device through the multiple connection frames 41, thereby achieving the transmission of the pressure on the device;
[0032] An extension plate 42 is fixedly connected to the connection frame 41, and the pneumatic telescopic rod 43 is conveniently connected by providing the extension plate 42;
[0033] like Figure 1 As shown, there are four extension plates 42, which are arranged vertically. By arranging the four extension plates 42 vertically and staggered in a cross shape, the pneumatic telescopic rod 43 is connected to the common intersection of the four extension plates 42, so that the pressure on the universal ball 1 can be transmitted to the pneumatic telescopic rod 43;
[0034] The extension plate 42 is fixedly connected with a pneumatic telescopic rod 43. By providing a starting telescopic rod, the starting telescopic rod has a certain shock absorbing effect and is low in cost.
[0035] like Figure 1 As shown, a chassis connection port 44 is fixedly connected to one side of the pneumatic telescopic rod 43 away from the extension plate 42. The chassis connection port 44 is provided to facilitate the connection of the pulling pile.
[0036] The above solution also has the problem that the universal joint structure cannot be connected to the pile body. Figure 1 , Figure 2 , Figure 3As shown, a ball 31 is rollingly connected inside the rotating drum 3, and a second rotating column 32 is rotatably connected to the side of the ball 31 away from the rotating drum 3. The first sliding column 23 is fixedly connected to the universal ball 1, and the top of the first sliding column 23 is fixedly connected to the connecting plate 24. By setting the first sliding column 23 and the universal ball 1 fixedly connected, the free movement of the first sliding column 23 is achieved. By setting the connecting plate 24, it is convenient to connect the extraction pile on the connecting plate 24, and it can usually be connected using connecting parts such as screws.
[0037] Working principle:
[0038] like Figure 1-4 As shown: when the universal ball 1 is subjected to pressure, the force will be transmitted through the first sliding column 23 fixedly connected thereto, the first sliding column 23 is connected to the rotating drum 3, and the rotating drum 3 further transmits the force through the connecting plate 4 and the connecting frame 41. Such a design enables the joint to withstand pressure from different directions and effectively transmit it to other parts of the device;
[0039] Four vertical extension plates 42 are arranged in a cross shape to increase the stability of the structure. The pneumatic telescopic rod 43 is connected to the intersection of the four extension plates 42 to evenly disperse the pressure, thereby reducing the impact on a single point.
[0040] Shock-absorbing effect: The pneumatic telescopic rod 43 itself has a certain shock-absorbing effect, which can absorb part of the impact force and reduce the impact of vibration on the entire structure. This design not only improves the durability of the equipment, but also reduces the noise and vibration during operation. The pneumatic telescopic rod 43 provides a shock-absorbing effect, making the pile pulling process smoother, reducing the impact on the surrounding environment, and also protecting the safety of the staff.
[0041] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
