[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-2 A pipe lifting device for construction engineering includes an installation plate 1 and proportionally deformable binding parts 2 distributed on both sides of the installation plate 1. The installation plate 1 has installation holes 12 for connecting with hoisting equipment. After the two sets of proportionally deformable binding parts 2 come into close contact with each other, they form a hexagonal structure in the middle for clamping a large number of small-diameter pipes and a single large-diameter pipe.

[0028] Meanwhile, the size of the hexagonal structure formed by the two sets of proportionally deformable binding parts 2 is adjustable, so as to achieve the gripping effect of different quantities and specifications of pipes. The proportionally deformable binding part 2 includes a connecting frame 21 slidably set on the mounting plate 1 and proportionally deformable parts installed on the connecting frame 21. A double-ended screw 11 is rotatably set on the mounting plate 1. The two sets of connecting frames 21 are sleeved on both sides of the double-ended screw 11 through threaded holes. The distance between the two sets of connecting frames 21 is controlled by the rotation of the double-ended screw 11. A motor 2 is fixed inside the mounting plate 1, and the output shaft of the motor 2 is fixedly connected to the double-ended screw 11 to drive the rotation of the double-ended screw 11, thereby controlling the two sets of proportionally deformable parts to move closer or further apart.

[0029] Please see Figures 3-4 The pipe lifting device for construction engineering has a proportionally deformable component consisting of four sets of connecting rods 23 and a folding rod group 28 located between two adjacent sets of connecting rods 23. The connecting rods 23 are located at the top corner of the polygonal structure, while the folding rod group 28 is used to control the side length of the polygonal structure. The set of connecting rods 23 located at the end is fixedly connected to the connecting frame 21.

[0030] Four sets of connecting rods 23 and three sets of folding rods 28 form three sides of one side of a hexagonal structure, and the spacing between two adjacent sets of connecting rods 23 in the proportional deformation part is equal.

[0031] Please see Figures 3-5 A pipe lifting device for construction engineering, wherein each connecting rod 23 is fitted with a fixing sleeve 1 24 and a fixing sleeve 25 on both ends, and a movable sleeve 26 is slidably fitted in the middle of the connecting rod 23;

[0032] The folding rod group 28 comprises rod one 281 and rod two 282 which are hingedly connected at their ends, and rod three 283 and rod four 284 which are hingedly connected at their middle parts, the distal ends of the rod one 281 and the rod two 282 are hingedly connected with the fixed sleeve one 24 on the adjacent two groups of connecting rods 23 respectively, the two ends of the rod three 283 are hingedly connected with the fixed sleeve two 25 on one group of connecting rods 23 and the movable sleeve 26 on the adjacent other group of connecting rods 23 respectively, and the two ends of the rod four 284 are hingedly connected with the movable sleeve 26 on one group of connecting rods 23 and the fixed sleeve two 25 on the adjacent other group of connecting rods 23 respectively;

[0033] Meanwhile, the outer diameter of the movable sleeve 26 is smaller than that of the fixed sleeve one 24 and the fixed sleeve two 25, so that the movable sleeve 26 can move smoothly when embracing the pipe, and the movable sleeve 26 will not be difficult to move due to the large frictional resistance between the movable sleeve 26 and the pipe;

[0034] The folding rod group 28 can control the change of the distance between the adjacent two groups of connecting rods 23 through the expansion and contraction, and since the adjacent two groups of folding rod groups 28 are connected through the same group of movable sleeves 26, the linkage of the expansion and contraction can be realized.

[0035] Please refer to Figure 3 The pipe lifting device for building engineering construction is provided with the convex seat 27 fixed on the movable sleeve 26 on one group of connecting rods 23 which is fixedly connected with the connecting frame 21, the convex seat 27 is slidingly connected with the connecting frame 21, and the convex seat 27 is threadedly connected with the adjusting screw rod 22 which is rotatably installed on the connecting frame 21 through the threaded hole formed on the convex seat 27, and the position of the movable sleeve 26 on the connecting rod 23 is controlled through the rotation of the adjusting screw rod 22.

[0036] The motor one is fixed in the connecting frame 21, and the output shaft of the motor one is fixedly connected with the adjusting screw rod 22, so as to drive the adjusting screw rod 22 to rotate and realize the function of controlling the distance between the connecting rods 23.
