[0025] 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.
[0026] In the description of the present invention, descriptions of directions, such as up, down, 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.
[0027] 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.
[0028] The embodiment of the present utility model provides an adaptive hook device, such as Figure 1 As shown, the hook body 100 includes a pressure piece 200 and an adjustment mechanism 300. The hook body 100 includes a hook body 110, a hook tail 120 connected to the upper end of the hook body 110, and a hook head 130 connected to the lower end of the hook body 110. The entire hook body 100 is shaped like a "C". A hook groove 101 is formed between the hook head 130 and the hook tail 120, into which the pile body 10 is inserted. After the pile body 10 is inserted into the hook groove 101, the pile body 10 can be hooked.
[0029] The adjusting mechanism 300 is arranged on the hook tail 120 and is connected to the pressing piece 200. The adjusting mechanism 300 is used to adjust the position of the pressing piece 200 along the height direction of the hook groove 101 to change the distance from the lower end of the pressing piece 200 to the hook head 130. For pile bodies 10 of different shapes and / or thicknesses, the position of the pressing piece 200 can be adjusted along the height direction of the hook groove 101, so that the hook head 130 and the pressing piece 200 clamp the pile body 10 inserted into the hook groove 101, thereby stably hooking the pile body 10, which enhances the versatility of the hook device.
[0030] In some embodiments, the adjustment mechanism 300 comprises a nut secured to the hook tail 120, and the pressure member 200 is a bolt threadedly connected to the nut, with the axial direction of the bolt parallel to the height of the hook slot 101. By tightening the bolt, the position of the bolt can be adjusted along the height of the hook slot 101 to accommodate different pile bodies 10. Furthermore, the threaded connection offers the advantage of ease of operation, making it easier for operators to tighten the bolt. Furthermore, due to the coordination between the bolt and the nut, the bolt maintains its position when not tightened and does not easily loosen, thereby providing a stable grip on the pile body 10.
[0031] Furthermore, the nut is fixed to the hook tail 120 by welding, which makes the welding fixation simpler and improves the stability of the fixation.
[0032] In other embodiments, the pressing piece can be slidably connected to the hook tail along the height direction of the hook groove, the adjustment mechanism may include a screw, the surface of the pressing piece is provided with a penetrating mounting hole, and the hook tail is provided with multiple threaded holes along the height direction of the hook groove. The screws pass through the mounting holes and are fixed in the threaded holes. By changing the threaded holes to which the screws are fixed, the position of the pressing piece can be adjusted along the height direction of the hook groove.
[0033] Of course, the adjustment mechanism may also be other mechanisms that can adjust the position of the pressing piece along the height direction of the hook groove.
[0034] In some embodiments, as Figure 1 and Figure 2 As shown, the pressing piece 200 and the adjusting mechanism 300 connected thereto are distributed in multiple groups along the direction in which the pile body 10 is inserted into the hook groove 101 , which can form multiple clamping points in the direction in which the pile body 10 is inserted into the hook groove 101 to improve the stability of the clamped pile body 10 .
[0035] For a special-shaped pile body with different heights in the direction of the pile body 10 inserted into the hook groove 101, the pressing pieces 200 distributed along the direction of the pile body 10 inserted into the hook groove 101 can be at different heights to adapt to the special-shaped pile body, thereby achieving a stable clamping of the pile body.
[0036] In some embodiments, as Figure 1 、 Figure 2 and Figure 3 As shown, both sides of the hook tail 120 are provided with a pressing piece 200 and an adjusting mechanism 300 connected thereto. This can form multiple clamping points in the width direction of the hook groove 101 to improve the stability of the clamping pile body 10.
[0037] For a special-shaped pile body with different heights in the width direction of the hook groove 101, the pressing pieces 200 on both sides of the hook tail 120 can be placed at different heights to adapt to the special-shaped pile body, thereby achieving a stable clamping of the pile body.
[0038] like Figure 4As shown in the figure, the pile body 10 is of a special-shaped structure, and the pressing pieces 200 on both sides of the hook tail are at different heights to adapt to the pile body 10 and thus firmly clamp the pile body 10.
[0039] In some embodiments, as Figure 1 As shown, the hook tail 120 is provided with a connection structure 102 for connecting with a wire rope or a hook, so as to connect the entire hook body 100 to a crane, thereby lifting the hook body 100.
[0040] Furthermore, the connecting structure 102 is a through-hole that passes through the hook tail 120 , and the wire rope can pass through the through-hole to be tied to the hook tail 120 , or the hook of the crane can be hooked in the through-hole.
[0041] In some embodiments, the inner side surfaces of the hook tail 120 and the hook head 130 facing each other are both flat, which can relatively increase the distance between the two sides of the hook head 130, thereby increasing the distance between the clamping points of the hook head 130 on the pile body 10 on both sides, thereby more stably clamping the pile body 10.
[0042] In some embodiments, the hook body 110 , the hook tail 120 , and the hook head 130 are integrally formed, which can simplify the molding process and enhance the structural strength of the connection between the hook body 110 , the hook tail 120 , and the hook head 130 .
[0043] An embodiment of the utility model also provides another adaptive hook device. Compared with the above embodiment, this embodiment sets an adjustment mechanism on the hook head and is also connected to the pressure piece. The adjustment mechanism is also used to adjust the position of the pressure piece along the height direction of the hook groove to change the distance from the upper end of the pressure piece to the hook tail. For piles of different shapes and / or thicknesses, the position of the pressure piece can be adjusted along the height direction of the hook groove, so that the hook tail and the pressure piece clamp the pile body inserted into the hook groove, and can also stably hook the pile body, which also enhances the versatility of the hook device.
[0044] Accordingly, when the adjustment mechanism may include a nut fixed on the hook head, the pressing piece is a bolt threadedly connected to the nut, and the axial direction of the bolt is parallel to the height direction of the hook groove.
[0045] Both sides of the hook head can be provided with a pressing piece and an adjusting mechanism connected thereto to form multiple clamping points in the width direction of the hook groove, thereby improving the stability of the clamping pile body.
[0046] The terms and words used in the above 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 above 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.
