Description
Technical Field
[0001] The utility model relates to the technical field of pile material hoisting, in particular to an integrated pile tip pipe pile hoisting structure. Background Art
[0002] Due to its strong technical advantages, the integrated pile tip pipe pile is widely used in most building constructions in modern architecture and infrastructure construction. Especially in scenarios such as deep foundation construction, bridge construction, and high-rise building foundation reinforcement, this type of pile material is usually made of prestressed concrete or steel, with high strength, high durability, and good load-bearing capacity. It can effectively penetrate soft soil layers to reach hard soil or rock layers, providing a stable foundation support for the upper structure.
[0003] However, due to its structural characteristics, it is often difficult to directly and stably connect the lifting tool with a traditional lifting tool during the hoisting and movement of the integrated pile tip pipe pile. At the same time, the simple rope hoisting method may also cause the pipe pile to be displaced under force in the air during pipe pile hoisting, resulting in pile body damage, construction delays, and even potential safety hazards to on-site personnel.
[0004] Especially for the pile tip part, during hoisting and handling before construction, damage to the pile tip caused by collision should be prevented to ensure that the pile tip remains sharp, which is beneficial to subsequent pile driving operations, improves construction efficiency and quality, and at the same time reduces unnecessary wear, extends the service life of the pointed pipe pile and its casing, and reduces the replacement frequency and maintenance cost.
[0005] Therefore, this application specifically proposes an integrated pile tip pipe pile hoisting structure to solve the above technical problems. Summary of the Utility Model
[0006] The main purpose of the utility model is to provide an integrated pile tip pipe pile hoisting structure that can stably and safely lift the pile tip pipe pile, protect the pile tip of the pipe pile from damage during hoisting, prevent hoisting slip, and has strong hoisting safety.

[0011] Preferably, one ends of the two lever shafts close to each other are connected to a connecting sling. The connecting pressing block and the lever shaft are both movably located in the through groove. During the process of hoisting the pointed pipe pile by the connecting sling, the two pressing plates are respectively used to cooperate with the pointed sleeve and the mating clamping member to fixedly clamp both ends of the pointed pipe pile.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0027] In the embodiment, please refer in detail to Figures 1 to 4 .
[0028] Refer to Figure 1 and Figure 2 as shown, the present utility model provides an integrated pile tip pipe pile hoisting structure for preventing the force application plane of the pointed pipe pile 1 from moving while hoisting the pointed pipe pile 1 through the connecting sling 2. The structure includes a pointed sleeve 3 located at one end of the pointed pipe pile 1 for sleeving the pile tip and a matching clamping member arranged at the other end of the pointed pipe pile 1. Both the pointed sleeve 3 and the matching clamping member are connected to the connecting sling 2 through a lever clamping assembly 5.
[0029] It should be noted here that, as Figure 4 shown, there should be a certain space left when the tip of the pointed pipe pile 1 is located inside the pointed sleeve 3.
[0030] Therefore, when the lever clamping assembly 5 is connected to the connecting sling 2, when the lever clamping assembly 5 presses the pointed sleeve 3, it is necessary to ensure that there is still an inward force in the pressing force direction of the pointed sleeve 3 at this time, that is, there is still an additional force when the pointed sleeve 3 is pressed to ensure that the tip of the pointed sleeve 3 will not collide with the inner wall of the pointed sleeve 3 when it is stressed and displaced.
[0031] Specifically, during the process of hoisting the pointed pipe pile 1 with the connecting sling 2, the pointed sleeve 3 can enclose and protect the tip part of the pointed pipe pile 1. During the process of hoisting the pointed pipe pile 1 with the connecting sling 2, two groups of lever clamping assemblies 5 can respectively cooperate with the pointed sleeve 3 and the cooperating clamping parts to press the two ends of the pointed pipe pile 1 to prevent the pointed pipe pile 1 from moving in the plane towards the outer end of the pointed sleeve 3 under stress, and further prevent the tip part of the pointed pipe pile 1 from moving towards the inner wall of the pointed sleeve 3 and colliding and being damaged.
[0032] And at this time, by pressing the pointed pipe pile 1 with the lever clamping assembly 5 of the pointed sleeve 3, it can cooperate with the cooperating clamping part to clamp the pointed pipe pile 1, and at the same time, the lever clamping assembly 5 on the cooperating clamping part can further prevent the pointed pipe pile 1 from moving in the plane under stress.
[0033] It should also be noted that the above-mentioned connecting sling 2 can directly adopt the sling structure for traditional building hoisting, and as Figure 1 and Figure 2 shown, the connecting sling 2 is composed of a connecting rope for connecting two groups of lever clamping assemblies 5 and a lifting rope arranged on the connecting rope. Therefore, during the hoisting and lifting process of the pointed pipe pile 1, by controlling the lifting and lowering of the lifting rope, the two groups of lever clamping assemblies 5 can be lifted by the connecting rope, and further, the pointed pipe pile 1 can be lifted while the pointed sleeve 3 and the cooperating clamping part clamp the pointed pipe pile 1.
[0034] In addition, due to the description in the background technology, the pointed pipe piles 1 used in this embodiment are all pile tip pipe piles for normal building use.
[0035] Furthermore, the lever clamping assembly 5 includes a through groove 51 opened on the pointed sleeve 3 or the cooperating clamping part along the length direction of the pointed pipe pile 1, a lever arm 52 arranged on the top of the pointed sleeve 3 or the cooperating clamping part, a lever shaft 53 rotatably arranged in the middle of the lever arm 52, a connecting pressure block 54 rotatably arranged at one end of the lever shaft 53, and a pressing plate 55 located at the bottom of the connecting pressure block 54. Specifically, the mutually close ends (the other ends far from the pressing plate 55) of the two groups of lever shafts 53 are connected to the connecting sling 2, and both the connecting pressure block 54 and the lever shaft 53 are movably located in the through groove 51.
[0036] It should be noted that in order to ensure the uniform force on the pointed pipe pile 1 during hoisting and lifting, the two groups of lever clamping assemblies 5 here should be arranged in mirror symmetry.
[0037] Therefore, specifically during the process of connecting the sling 2 to hoist the pointed pipe pile 1, the lever shaft 53 rotates under the tension of the sling, driving the connecting pressure block 54 to press down the pressing plate 55, thereby generating a uniform and strong downward pressure at both ends of the pipe pile. At this time, with the cooperation of the pointed sleeve 3 and the cooperating clamping member, effective clamping of both ends of the pointed pipe pile 1 can be achieved, effectively preventing sliding during hoisting and reducing stress concentration at the stress points.
[0038] At this time, it should be noted that in order to ensure that the pressing plate 55 presses the pointed pipe pile 1 to prevent the pointed pipe pile 1 from moving towards the inner wall of the pointed sleeve 3 under force and thus contacting and colliding with the inner wall of the pointed sleeve 3 and being damaged, during actual use, the connecting sling 2 should be connected to the end closer to the lever shaft 53.
[0039] In summary, by setting the pointed sleeve 3, the pointed sleeve 3 can enclose and accommodate the pile tip part of the pipe pile. And by arranging the lever clamping assembly 5 outside the pointed sleeve 3 and the cooperating clamping member, it can not only provide additional stability for the pointed sleeve 3 during hoisting, enabling the pointed sleeve 3 and the cooperating clamping member to stably load and clamp the pipe pile during the hoisting and lifting process, but also make full use of the lever clamping assembly 5 to control the clamping of both ends of the pipe pile, so that the pipe pile can be protected from being damaged due to excessive force or slipping during hoisting, increasing the area of the stress points and the roughness of the contact surface, thereby improving the safety and reliability in the overall hoisting process.
[0040] Therefore, this structure not only increases the stability during hoisting, but also ensures the integrity of the pipe pile during hoisting by increasing the stress area and the roughness of the contact surface, reducing the damage risk, and improving the safety and operation efficiency of the construction.
[0041] In a specific embodiment, the cooperating clamping member can be set to have the same structure as the pointed sleeve 3, and the through groove 51 is opened at the top of the pointed sleeve 3.
[0042] Since the cooperating clamping member has the same structure as the pointed sleeve 3, both ends of the entire pointed pipe pile 1 are symmetrically and evenly supported and protected, effectively avoiding deformation or damage caused by uneven force during hoisting.
[0043] In a specific embodiment, the cooperating clamping member is also set as a U-shaped clamping arm 4 in a horizontal posture. The bottom of the U-shaped clamping arm 4 extends into the pointed pipe pile 1, and the through groove 51 is opened at the top of the U-shaped clamping arm 4. The structure of the U-shaped clamping arm 4 here not only ensures the tightness of the clamping, but also improves the adaptability to pipe piles of different diameters, enabling rapid adaptation to different hoisting conditions and pipe pile specifications on-site and improving the construction efficiency.
[0044] Specifically, by introducing a pointed sleeve 3 at one end of the pipe pile to accommodate the pile tip, the conical pile tip can be effectively fixed, avoiding instability during direct hoisting. And the mating clamping member at the other end (which can be a pointed sleeve 3 or a U-shaped clamping arm 4 of the same structure) ensures that the other end of the pointed pipe pile 1 is firmly supported. In summary, the overall stability during structure hoisting can be greatly enhanced.
[0045] It should also be noted that in actual use, different types of mating clamping members can be adopted according to actual construction requirements and the structure of the pipe pile. And the mating clamping members here are not limited to the above-mentioned pointed sleeve 3 and U-shaped clamping arm 4. The mating clamping member can also be replaced by other existing structures that can limit and control the pipe pile end. And at this time, by adopting different mating clamping members, the requirements of pipe piles with different diameters and shapes can also be adapted.
[0046] In a specific embodiment, one end of the pointed sleeve 3 is provided with a conical closure, which is used to safely and stably accommodate the pile tip of the pointed pipe pile 1. At the same time, the conical closure at one end of the pointed sleeve 3 can also prevent the pile tip from accidentally coming out or sliding during hoisting, ensuring a tight fit between the pile tip and the inside of the pointed sleeve 3, and remaining stable even when encountering vibration or external interference during hoisting operations.
[0047] At this time, during the hoisting process of the pipe pile, if the conical closure of the pointed sleeve 3 is collided, since the lever clamping assembly 5 controls the pressure plate 55 to press the pointed sleeve 3, there can be a downward clamping force on the clamped part of the pipe pile and a force in the opposite direction to the pointed sleeve 3, ensuring that the pipe pile and the pointed sleeve 3 are synchronously stressed and move in the air, avoiding contact between the tip and the sleeve.
[0048] At the same time, under the action of the connecting sling 2, the lever clamping assembly 5 not only fastens the pointed sleeve 3, but also applies an additional inward force to keep the tip position stable, ensuring that when encountering external collision during hoisting, the overall balance and safety of the pipe pile can be maintained through the reverse force of this structure, improving the safety and efficiency of hoisting operations.
[0049] In a specific embodiment, as Figure 3 shown, one end of the pointed sleeve 3 is provided with a conical opening 31, which can better match the conical pile tip of the pointed pipe pile 1 and is used to accommodate the pile tip of the pointed pipe pile 1. And in specific use, it can not only help guide the pile tip accurately into the inside of the pointed sleeve 3, but also have good stability and the effect of limiting the pointed pipe pile 1. At the same time, it can also adapt to pointed pipe piles 1 with different specifications of pile tips for nested limiting, improving the versatility and flexibility of use.
[0050] It should also be noted that the connection end of the connecting sling 2 on the lever shaft 53 is not unique at this time.
[0051] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
[0052] In addition, it should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.
[0053] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present utility model, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the meaning of "and / or" appearing throughout the text includes three parallel schemes. Taking "A and / or B" as an example, it includes Scheme A, Scheme B, or a scheme where A and B are satisfied simultaneously. In addition, in the embodiments of the present utility model, "a plurality" means two or more. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.
