[0027] The utility model provides the following description of reference drawings to help comprehensively understand various embodiments of the utility model as defined by the claims and its equivalents. The description includes various specific details to help understanding, but these details should be regarded as just exemplary. Therefore, those skilled in the art will realize that various changes and modifications can be made to various embodiments described herein without departing from the scope and spirit of the utility model.
[0028] In the description of the utility model, the orientation description such as the orientation or position relationship indicated by up, down, front, back, left, right etc. based on the orientation or position relationship shown in the drawing, is just for the convenience of describing the utility model and simplifying the description, and is not to indicate or imply that the device or element indicated must have a particular orientation, be constructed and operated in a particular orientation, therefore can not be understood as the limitation of the utility model.
[0029] It should be understood that when one element (for example, a first element) is "connected" with another element (for example, a second element), the element can be directly connected with another element, or there can be an intervening element (for example, a third element) between the element and another element.
[0030] The embodiment of the utility model provides a kind of lifting device for the quick stripping of concrete pipe pile, such as Figure 1 And Figure 2As shown, the structure includes a main frame 100, a hook 200, a sliding rod 300, two connecting rods 400, and two lifting rods 500. The hook 200 is connected to the main frame 100 and is used to hook and lift pipe piles. The two connecting rods 400 and the two lifting rods 500 are respectively arranged on both sides of the main frame 100. That is, the two connecting rods 400 are respectively arranged on both sides of the main frame 100, and the two lifting rods 500 are also respectively arranged on both sides of the main frame 100. The sliding rod 300 is slidably connected to the main frame 100. When the sliding rod 300 is subjected to external forces, it can slide relative to the main frame 100. The two lifting rods 500 are both inclined relative to the vertical direction, which allows them to deflect vertically during subsequent operation. When the lifting rods 500 deflect vertically, the height of their upper ends increases, which has an upward lifting effect, while the height of their lower ends tends to decrease, which can compress objects downward. The upper ends of the two lifting rods 500 are rotatably connected to either side of the main frame 100, and the lower ends of both lifting rods 500 are used to abut the mold. One end of one connecting rod 400 is rotatably connected to one end of the sliding rod 300, and one end of the other connecting rod 400 is rotatably connected to the other end of the sliding rod 300. The other end of one connecting rod 400 is rotatably connected to the middle of the adjacent lifting rod 500, and the other end of the other connecting rod 400 is rotatably connected to the middle of the adjacent lifting rod 500. When the sliding rod 300 is lifted, it slides relative to the main frame 100, and the connecting rod 400 drives the lifting rod 500 to deflect vertically.
[0031] When using the lifting device for rapid demoulding of concrete pipe piles of this embodiment, as shown in FIG. Figure 3 As shown, the hook 200 hooks the pipe pile 20 to be demoulded, and the lower ends of the two lifting rods 500 are both against the mold 10, and the lifting equipment such as the crane is connected to the sliding rod 300, so that the lifting device for rapid demoulding of concrete pipe piles in this embodiment is equivalent to replacing the main hook of the lifting equipment. Then the lifting device lifts the sliding rod 300, which slides relative to the main frame 100, thereby driving the connecting rod 400 to move. The connecting rod 400 then drives the lifting rod 500 to deflect in the vertical direction. The lower end of the lifting rod 500 presses the mold 10, limiting the mold 10 from moving upward with the pipe pile 20. The upper end of the lifting rod 500 and the lifting device drive the main frame 100 to move upward, which in turn drives the hook 200 connected to the main frame 100 to move upward. The hook 200 lifts the pipe pile 20, and the mold 10 is pressed, thereby separating the pipe pile 20 from the mold 10, achieving rapid demolding of the pipe pile 20. This eliminates the need for workers to hammer the mold 20, thereby improving production efficiency. At the same time, it also avoids the problems of mold deformation, mold quality reduction, and product quality reduction caused by hammering the mold 10, thereby improving the quality of the formed pipe pile.
[0032] In some embodiments, as Figure 1 andFigure 4 As shown, the main frame 100 includes a main rod 110 and two support rods 120. The two support rods 120 are arranged in parallel, and the two ends of the main rod 110 are respectively connected to the two support rods 120. The hook 200 is connected to the main rod 110, and the two connecting rods 400 are respectively arranged on the outside of the two support rods 120. The two lifting rods 500 are respectively arranged on the outside of the two support rods 120, and the upper ends of the two lifting rods 500 are respectively rotatably connected to the two support rods 120.
[0033] The main frame 100 of this embodiment has a simple structure and a relatively compact overall layout. The two lifting rods 500 are spaced a certain distance apart through the main frame 100, so that the two lifting rods 500 can respectively abut against the two side edges of the mold.
[0034] Furthermore, both support rods 120 are provided with a penetrating sliding groove 101, and the extension directions of the sliding grooves 101 on the two support rods 120 are parallel to each other. The two ends of the sliding rod 300 respectively pass through the sliding grooves 101 on the two support rods 120 and can slide in the sliding grooves 101, thereby allowing the sliding rod 300 to slide relative to the main frame 100.
[0035] In this embodiment, the sliding grooves 101 on the two support rods 120 can be aligned with each other or staggered. When the sliding grooves 101 on the two support rods 120 are staggered, the sliding rod 300 can have a bent structure to ensure that both ends of the sliding rod 300 can pass through the sliding grooves 101 on the two support rods 120. The lengths of the sliding grooves 101 on the two support rods 120 can be relative to each other to ensure that the maximum travel of the two ends of the sliding rod 300 remains consistent.
[0036] In some embodiments, as Figure 1 and Figure 4 As shown, the lifting device for rapid demoulding of concrete pipe piles also includes a rotating rod 510, and the two support rods 120 are both provided with a through-hole 121, and the through-holes 121 on the two support rods 120 are coaxially arranged. The two ends of the rotating rod 510 respectively pass through the through-holes 121 on the two support rods 120 and are respectively connected to the upper ends of the two lifting rods 500, and the rotating rod 510 can rotate in the through-hole 121, so that the lifting rod 500 can rotate relative to the support rod 120.
[0037] Since the two jacking rods 500 use the same rotating rod 510, the two can rotate synchronously, so that both sides of the main frame 100 can move upward synchronously, improving the stability of the main frame 100 during lifting and lifting the pipe pile more stably.
[0038] In some embodiments, as Figure 1 and Figure 4As shown, the hook 200 is arranged on the front side of the main rod 110, and the main rod 110 is located at one end of the front side of the support rod 120. The hook 200 is relatively far away from the sliding rod 300, the connecting rod 400 and the lifting rod 500, and does not affect the movement of the sliding rod 300, the connecting rod 400 and the lifting rod 500.
[0039] In this embodiment, the hook 200 may be located in the middle of the main rod 110 .
[0040] Furthermore, the hook 200 includes a connecting rod 210, a vertical rod 220 and a hook rod 230. The vertical rod 220 is arranged in a vertical direction. One end of the connecting rod 210 is connected to the main rod 110, and the other end extends to the front side of the main rod 110 and is connected to the upper end of the vertical rod 220. The lower end of the vertical rod 220 is connected to one end of the hook rod 230, and the other end of the hook rod 230 extends to the rear side. The hook rod 230 can be inserted backward from the end of the pipe pile into the center hole of the pipe pile to hook its pipe pile.
[0041] In the above embodiment, the main rod 110, the support rod 120, the connecting rod 210, the vertical rod 220 and the hook rod 230 can be integrally formed, which facilitates the molding of the main frame 100 and the hook 200, simplifies the manufacturing process, and can also enhance the connection strength between them.
[0042] In some embodiments, as Figure 2 As shown, the sliding direction of the sliding rod 300 on the main frame 100 is tilted relative to the vertical direction, so that the sliding rod 300 can have a higher sliding position and a lower sliding position relative to the main frame 100. Figure 2 For example, the sliding groove 101 is tilted toward the upper right, with the upper right end of the sliding groove 101 being a higher sliding position, and the lower left end of the sliding groove 101 being a lower sliding position. The higher sliding end of the sliding rod 300 is close to the upper end of the lifting rod 500, and in the vertical downward direction, the lower end of the lifting rod 500 gradually approaches the lower sliding end of the sliding rod 300. That is, relative to the vertical direction, the sliding direction of the sliding rod 300 on the main frame 100 and the extension direction of the lifting rod 500 are both tilted toward the same side.
[0043] by Figure 2 For example, when the lifting equipment lifts the sliding rod 300, the sliding rod 300 slides to the upper right, the angle between the connecting rod 400 and the lifting rod 500 is reduced, the connecting rod 400 applies a thrust to the lifting rod 500, and the lower end of the lifting rod 500 rotates to the right, causing the entire lifting rod 500 to deflect in the vertical direction. The lower end of the lifting rod 500 can press the mold, and the upper end of the lifting rod 500 can drive the hook 200 to move upward.
[0044] In some embodiments, as Figure 1As shown, the surface of the sliding rod 300 is provided with an annular groove 310, and the annular groove 310 can surround the sliding rod 300. The main hook of the lifting equipment can be hooked at the annular groove 310, or the lifting rope of the lifting equipment can be wound in the annular groove 310. The annular groove 310 can position the main hook and the lifting rope, limit the axial movement of the main hook and the lifting rope along the sliding rod 300, and ensure that the lifting equipment can lift the pipe pile smoothly.
[0045] In some embodiments, as Figure 3 As shown, the end face of the lower end of the lifting rod 500 is configured to match the edge of the lower mold, so that the lower end of the lifting rod 500 can be close to the edge of the lower mold, increasing the contact area with the edge of the lower mold. On the one hand, it can stably press the lower mold, and on the other hand, it avoids stress concentration and is not easy to damage the lower mold.
[0046] The lower ends of the two lifting rods 500 can respectively abut against the two edges of the lower mold, so that the lower mold remains stable and does not tilt on one side.
[0047] In some embodiments, as Figure 1 As shown, the rotation axes of the sliding rod 300 and the connecting rod 400, the rotation axes of the connecting rod 400 and the lifting rod 500, and the rotation axes of the lifting rod 500 and the main frame 100 are parallel to each other. The connecting rod 400 and the lifting rod 500 can rotate on parallel or identical planes, maximizing the force transmitted between them and ensuring stable rotation of the connecting rod 400 and the lifting rod 500.
[0048] 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.
