[0002] Concrete pipe piles can be divided into post-tensioned prestressed pipe piles and pre-tensioned prestressed pipe piles. Pre-tensioned prestressed pipe piles are slender precast concrete components with hollow cylinders made by pre-tensioning technology and centrifugal forming. They are mainly composed of cylindrical pile bodies, end plates and steel sleeves. At present, due to the heavy weight of pipe piles, cranes and slings are generally used in combination to move the pipe piles.

[0003] In the prior art, the method for lifting pipe piles is that the staff hangs the hook on the lifting hole of the pipe pile or the pipe pile mold and then lifts it to move; since the pipe pile is heavy and the force-bearing area between the hook and the lifting hole is small, the force friction between the hook and the lifting hole is increased, which correspondingly reduces the use effect and service life of the hook. At the same time, the force friction between the hook and the lifting hole is easy to cause damage to the lifting hole, which correspondingly reduces the secondary lifting effect of the pipe pile. Therefore, a clamp type pipe pile lifting device is proposed. Utility Model Content

Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The embodiment provides a hoop type pipe pile lifting device, such as Figures 1 to 4 As shown, it includes a pipe pile body 2, a traction rope 4 and at least two groups of lifting sleeves 1 sleeved on the pipe pile body 2, and two adjacent groups of lifting sleeves 1 are connected by a telescopic connecting rod 3, and the traction rope 4 is connected to the telescopic connecting rod; the lifting sleeve 1 is a cylindrical structure composed of two arc-shaped connecting sleeves 100 and two arc-shaped slide plates 103 connected between the two arc-shaped connecting sleeves 100, the two arc-shaped connecting sleeves 100 are symmetrically arranged up and down, and the two arc-shaped slide plates 103 are symmetrically distributed left and right. A fixing plate 101 is provided in each arc-shaped connecting sleeve 100, and the fixing plate 101 symmetrically divides the inner cavity of the arc-shaped connecting sleeve 100 into two arc-shaped grooves. Clamping springs 102 are fixedly connected to both sides of the fixing plate 101, and the two ends of the arc-shaped slide plate 103 are respectively embedded in the arc-shaped grooves in the two adjacent arc-shaped connecting sleeves 100, and the ends are fixedly connected to the corresponding clamping springs 102. The arc-shaped slide plate 103 can slide in the arc-shaped groove, so as to adjust the diameter of the lifting sleeve 1, so as to facilitate the sleeve on the pile body 2. The set clamping spring 102 can make the lifting sleeve 1 closely contact with its surface after being sleeved on the pile body 2, so as to clamp the pile body 2.

[0020] The embodiment provides a hoop type pipe pile lifting device, such as Figures 1 to 4 As shown, the telescopic connecting rod 3 includes a telescopic sleeve 300 and a telescopic plate 301, one end of the telescopic plate 301 is embedded in the telescopic sleeve 300 and slides horizontally in the telescopic sleeve 300, and the other end is connected to the arc-shaped connecting sleeve 100 above one of the lifting sleeves 1, and the other end of the telescopic sleeve 300 is connected to the arc-shaped connecting sleeve 100 above the adjacent lifting sleeve 1; a limit plate 304 is provided at the end of the telescopic plate 301 embedded in the telescopic sleeve 300, and a traction rope 4 is connected to the top of the telescopic sleeve 300 and the telescopic plate 301; a plurality of limit holes 305 are correspondingly opened on the telescopic sleeve 300 and the telescopic plate 301, a connecting rope 302 is connected to one side of the outer wall of the telescopic sleeve 300, and a limit pin 303 matching the limit hole 305 is connected to the end of the connecting rope 302 away from the telescopic sleeve 300. The telescopic sleeve 300 and the telescopic plate 301 are both strip structures, the limiting holes 305 are opened on the sides of the telescopic sleeve 300 and the telescopic plate 301 in the length direction, and the plurality of limiting holes 305 are evenly distributed, the length of the connecting rope 302 can cover the distribution length of the limiting holes 305, and the connecting rope 302 is configured as an elastic rope, and when the telescopic plate 301 slides to the set position in the telescopic sleeve 300, the limiting pin 303 is inserted into the corresponding limiting hole 305 to fix the limit.

[0021] It should be noted that: according to the function of the connecting rope 302, the limit pin 303 can be stably located on the outer wall of the telescopic sleeve 300, which is convenient for the staff to use it. At the same time, according to the function of the limit plate 304, the telescopic plate 301 can be slidably limited to prevent the telescopic plate 301 from directly sliding and extending to the outside of the telescopic sleeve 300, thereby improving the sliding adjustment effect of the telescopic plate 301 and the telescopic sleeve 300;

[0022] Through the setting of the above technical scheme, the lifting coverage area of ​​the staff when lifting the pipe pile body 2 is increased according to the lifting sleeve 1. Compared with the lifting method through the hook and the lifting hole, the large friction in the hook hand is avoided, and the use effect of the hook and the traction rope 4 is correspondingly improved. At the same time, the setting of the lifting hole being damaged is avoided, thereby improving the effect of the secondary lifting of the pipe pile body 2.

[0023] The functional principle of the utility model can be explained through the following operation mode: when the staff lifts the pipe pile body 2, first slide the lifting sleeve 1, and according to the sliding effect of the arc-shaped slide plate 103 and the arc-shaped connecting sleeve 100, the diameter of the lifting sleeve 1 becomes larger, and it can be conveniently mounted on the pipe pile body 1; because the arc-shaped connecting sleeves 100 of two adjacent lifting sleeves 1 are connected by the telescopic connecting rod 3, only one of the lifting sleeves 1 needs to be adjusted, and the adjacent lifting sleeves 1 can be adjusted when passing through, which reduces the operating steps of the staff and facilitates the adjustment operation of the staff.

[0024] After the diameter adjustment of the lifting sleeve 1 is completed, the lifting sleeve 1 is sleeved on the outer wall of the pipe pile body 2, so that the inner wall of the lifting sleeve 1 and the outer wall of the pipe pile body 2 are slidably fitted, and the lifting sleeve 1 is correspondingly located on the outer wall of the pipe pile body 2, and then the pipe pile body 2 is lifted by the lifting action of the traction rope 4. Through the setting of this structure, the lifting coverage area of ​​the staff when lifting the pipe pile body 2 is increased. Compared with the lifting method through the hook and the lifting hole, the large friction in the hook hand is avoided, and the use effect of the hook and the traction rope 4 is correspondingly improved. At the same time, the setting of the lifting hole damage is avoided, thereby improving the secondary lifting effect of the pipe pile body 2.

[0025] The telescopic connecting rod 3 of the utility model can also adjust the distance between two adjacent lifting sleeves 1, slide the telescopic plate 301 to increase the distance between the two horizontal lifting sleeves 1, and then insert the limit pin 303 into the fixing hole to fix the telescopic plate 301 and the telescopic sleeve 300. Accordingly, based on such settings, this structure is suitable for pipe pile bodies 2 of different lengths, so that the two sets of clamping and mounting mechanisms are symmetrically arranged on the pipe pile body 2, which correspondingly increases the stability of the two sides of the pipe pile body 2 during lifting, thereby improving the lifting efficiency of the pipe pile body 2 by the staff.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
