Description

Technical Field

[0001] The utility model relates to the technical field of wave pile lifting, in particular to a wave pile transfer device. Background Art

[0002] At present, with the rapid development of urban construction in my country, prestressed concrete piles have been widely used in key areas of infrastructure construction such as industrial and civil buildings, municipal bridges, and highways due to their high bending strength, factory production, energy saving and environmental protection, and wide range of applications.

[0003] In the existing lifting process of hollow piles such as pipe piles and hollow square piles, a C-shaped hook is usually used. The lower part of the hook body is the hook head, the lower part is the hook tail, and the middle part is the hook body. A wire rope hole is provided under the hook tail. The specific application is: the hook heads of the two hooks are respectively inserted into the center holes at both ends of the hollow pile, and then two steel wire ropes are respectively connected to the wire rope holes of the hook tails of the two hooks, and finally the two wire ropes are gathered under the hook of the crane for lifting.

[0004] However, there are now many non-hollow wave piles on the market with non-closed-loop pile bodies. The cross-section of this type of wave pile is roughly semi-circular. There are no closed hollow holes at both ends of this type of pile that can accommodate traditional hooks. If traditional hooks are used for lifting, the wave pile will tilt and cannot be lifted. If a hook with a center-mounted clamping size that matches the wall thickness of the wave pile is used, although it can clamp the pile body tightly and prevent it from tilting and unhooking, the same hook cannot be used for wave piles of different shapes and wall thicknesses. A dedicated hook must be replaced for each pile specification, resulting in reduced lifting efficiency and economic waste. Utility Model Content

[0005] The utility model provides a transport device for wave piles, which can be applied to wave piles of different specifications, improves lifting efficiency and reduces lifting costs.

[0026] The following description of the present invention, with reference to the accompanying drawings, is provided to facilitate a more comprehensive understanding of the various embodiments of the present invention as defined in the claims and their equivalents. The description includes various specific details to assist understanding, but these details should be construed as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the various embodiments described herein without departing from the scope and spirit of the present invention.

[0027] In the description of the present invention, descriptions of directions, such as down, lower, front, back, left, right, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0028] It will be understood that when one element (e.g., a first element) is “connected” to another element (e.g., a second element), the element may be directly connected to the other element or an intervening element (e.g., a third element) may be present between the element and the other element.

[0029] The embodiment of the present utility model provides a transport device for wave piles, such as Figure 1 As shown, the hook body and adjustable pressure piece 400 are included. The hook body comprises a hook body 100, an upper support hook 200 connected to the upper end of the hook body 100, and a lower support hook 300 connected to the lower end of the hook body 100. The entire hook body is shaped like a "C." A hook slot is formed between the upper support hook 200 and the lower support hook 300 for inserting a wave pile. Once the wave pile is inserted into the hook slot, the hook body can hook the wave pile.

[0030] The adjustable pressing piece 400 is connected to the upper support hook 200. The lower end of the adjustable pressing piece 400 extends into the hook groove so that it can press on the wave pile located in the hook groove. The adjustable pressing piece 400 can be adjusted along the height direction of the hook groove to change the distance between the lower end of the adjustable pressing piece 400 and the lower support hook 300. Figure 2 and Figure 3 As shown, for wave piles 10 of different specifications, the adjustable pressing piece 400 can be adjusted along the height direction of the hook groove so that the lower end of the adjustable pressing piece 400 and the lower supporting hook 300 clamp the wave pile 10 inserted into the hook groove.

[0031] Therefore, the wave pile transfer device of this embodiment can be applied to wave piles of different specifications, and is more versatile. When lifting wave piles of different specifications, there is no need to disassemble and replace different hooks. Wave piles of different specifications can be hooked quickly and stably, which improves lifting efficiency and reduces lifting costs.

[0032] In some embodiments, the adjustable pressure piece 400 is a bolt, and the upper supporting hook 200 is provided with a threaded hole adapted for the bolt. The threaded hole extends along the height direction of the hook groove and passes through the upper supporting hook 200. The bolt is passed through the threaded hole and is threadedly connected to the threaded hole.

[0033] During use, the lower end of the bolt can be moved along the height direction of the hook groove by screwing the bolt to change the position of the adjustable pressing member 400. This method is simpler to operate, and the threaded connection provides sufficient strength. After the position of the bolt is adjusted, it is not easy to move along the height direction of the hook groove by itself, and the adjusted position can be maintained.

[0034] The threaded hole can be located on the midline of the width direction of the lower supporting hook 300. When clamping the wave pile, the bolt can be in a relatively central position, the force is relatively balanced, and the wave pile can be clamped more stably.

[0035] In some embodiments, the width of the lower support hook 300 is greater than that of the upper support hook 200. When hoisting a wave pile, the lower support hook 300 primarily provides the hooking force. Therefore, setting the width of the lower support hook 300 greater than that of the upper support hook 200 increases the distance between the two points where the lower support hook 300 contacts the wave pile, enabling more stable hooking of the wave pile. Furthermore, the lower support hook 300 has a relatively greater structural strength and durability.

[0036] In some embodiments, the lower end of the adjustable pressure piece 400 is provided with an elastic body. When clamping the wave pile, the elastic body can elastically deform, thereby increasing the contact area between the adjustable pressure piece 400 and the wave pile, preventing the wave pile from sliding and providing a more stable hook. At the same time, excessive pressure is avoided, making the force on the contact surface more uniform and less likely to damage the wave pile.

[0037] In some embodiments, the upper support hook 300 is provided with a connection structure 500 for connecting to a wire rope or a hook, so as to connect the entire hook body to a crane, thereby lifting the hook body.

[0038] Furthermore, the connection structure 500 includes a lug 510 and a through-hole 520 provided on the lug 510 . A steel wire rope can pass through the through-hole to be tied to the lug 510 , or a hook of a crane can be hooked in the through-hole.

[0039] In some embodiments, the upper supporting hook 200 includes two upper supporting blocks 210 and an upper supporting plate 220. The upper supporting plate 220 is located between and connected to the two upper supporting blocks 210. The lower supporting hook 300 includes two lower supporting blocks 310 and a lower supporting plate 320. The lower supporting plate 320 is located between and connected to the two lower supporting blocks 310. When hooking the wave pile, the two lower supporting blocks 310 are in contact with the wave pile.

[0040] Furthermore, the hook body 100 includes two connecting plates 110. The ends of one connecting plate 110 are respectively connected to one of the upper supporting blocks 210 and one of the lower supporting blocks 310, while the ends of the other connecting plate 110 are respectively connected to the other upper supporting block 210 and the other lower supporting block 310. A gap is left between the two connecting plates 110. While ensuring structural strength, this can reduce the material used in the entire wave pile transfer device and save costs.

[0041] Furthermore, the two lower supporting blocks 310 can be tilted relative to the vertical direction, and the distance between the two lower supporting blocks 310 gradually decreases in the upward extending direction. The two upper supporting blocks 210 can also be tilted relative to the vertical direction, and the distance between the two upper supporting blocks 210 also gradually decreases in the upward extending direction.

[0042] When the width of the lower supporting hook 300 is greater than the width of the upper supporting hook 200 , the two connecting plates 110 , the upper supporting hook 200 and the lower supporting hook 300 are combined to form a trapezoidal structure that is wider at the bottom and narrower at the top.

[0043] In some embodiments, the hook body 100 , the upper supporting hook 200 and the lower supporting hook 300 are integrally formed, which can simplify the molding process and improve the structural strength of the connection between the hook body 100 , the upper supporting hook 200 and the lower supporting hook 300 .

[0044] The terms and words used in the following description and claims are not limited to their literal meanings, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, it should be clear to those skilled in the art that the following description of various embodiments of the present invention is provided for illustration only and is not intended to limit the present invention as defined in the appended claims and their equivalents.
