[0002] Concrete poles are poles made of concrete and steel bars or steel wires. They need to be lifted when they are moved or loaded. The crane pulls the cables and drives the poles to rise.

[0003] Due to the different lengths and diameters of the produced poles, the balance point of each concrete pole is different. For example, a pole lifting fixture with application number 202211230808.X needs to move the lifting structure to the balance point first and then lift it when lifting the concrete pole. This lifting structure requires workers to level it multiple times, which increases the lifting time. In addition, when lifting concrete poles of different lengths, they need to be centered and aligned, which increases the work intensity and is inconvenient to use. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0029] According to the concept of this application, Figures 1 to 4 To describe an embodiment of a hoisting structure for the production of annular concrete poles. Specifically, the hoisting structure is constructed as a split structure, which has three components, namely, a screw 1, a fixing assembly 3 and a fixing seat 5. The rotating shaft 301 moves in the horizontal direction, thereby driving the connecting rod 302 and the clamping block 303 to expand and contract outward from the center of the screw 1, so that the fixing assembly 3 can adapt to concrete poles of different diameters, and can fix and support one end of the concrete pole. By sleeved the first steel cable 7 on the other end of the concrete pole, it can be directly hoisted, which can avoid finding a balance point and is conducive to saving hoisting time. By threading the fixing seat 5 with the cross screw 51 and the first connecting member 52, the number of concrete poles hoisted by the device at one time can be increased.

[0030] Please refer to Figures 1 to 4 A hoisting structure for producing annular concrete poles, comprising: a fixing assembly 3; a fixing ring 11 is fixed to the right end of a screw rod 1, and the fixing assembly 3 is located outside the screw rod 1, the fixing assembly 3 comprises a rotating shaft 301, a connecting rod 302 and a clamping block 303, a plurality of connecting rods 302 are arranged around the outside of the rotating shaft 301, and a clamping block 303 is hinged on the side of the connecting rod 302 away from the rotating shaft 301;

[0031] A fixing seat 5 is fixed to the right side of the fixing ring 11, and a cross screw 51 is provided through the inner side of the fixing seat 5, and a plurality of first connecting members 52 are threadedly connected to the outer side of the cross screw 51;

[0032] The fixing assembly 3 is used to support the entire concrete pole. When the rotating shaft 301 moves laterally, it will drive the connecting rod 302 and the clamping block 303 to expand or contract outward with the screw rod 1 as the center, so as to adapt to concrete poles of different diameters. The inner side of the clamping block 303 is a fixing groove. When the diameter of the clamping block 303 is the same as that of the concrete pole, the concrete pole can be inserted into the clamping block 303, which can prevent the concrete from rotating during the lifting process. The concrete pole is supported by the thread and the connecting rod 302, which can improve the stability of the device.

[0033] The cross screw 51 on the inner side of the fixing seat 5 and the first connecting member 52 are connected by a threaded connection, and other fixing seats 5 can be installed horizontally or vertically on the outer side of the fixing seat 5, and the first connecting member 52 is tightened on the outer side of the cross screw 51, so that multiple groups of fixing seats 5 can be spliced, so that multiple groups of concrete poles can be hoisted at the same time. In other embodiments of the present application, the cross screw 51 and the first connecting member 52 are removed, and the connection and fixing effect can also be achieved by directly inserting a steel wire rope into the interior of the fixing seat 5.

[0034] The outer side of the screw rod 1 is threadedly connected with the nut 2, and the rotating shaft 301 is located on the outer side of the nut 2. The rotating shaft 301 rotates on the outer side of the nut 2, so that the rotating shaft 301 forms a sliding structure with the screw rod 1 through the nut 2, which can change the rotational motion of the nut 2 on the screw rod 1 into linear motion, which is used to change the direction of motion, and realize self-locking through the thread, thereby improving the stability of the device;

[0035] A plurality of sets of hinged seats 322 are fixed around the outer side of the fixing ring 11 at equal intervals, and a support rod 321 is hinged between the hinged seat 322 and the clamping block 303. The support rod 321 is used to connect the fixing ring 11 and the clamping block 303, so that a triangular structure is formed between the screw rod 1, the connecting rod 302 and the support rod 321, which can further improve the support of the device and the carrying capacity of the device. A plurality of fixing blocks 41 are equidistantly arranged on the outer side of the fixing ring 11 and the rotating shaft 301 for fixing the telescopic rod 4, and the inner sides of the plurality of fixing blocks 41 are all fixed with the telescopic rod 4, which is used to reinforce the support between the rotating shaft 301 and the fixing ring 11, and is used to further improve the carrying capacity of the device.

[0036] A through hole 511 adapted to the cross screw 51 is provided on the inner side of the fixing seat 5, which is used to limit the position of the cross screw 51 and prevent the cross screw 51 from falling off during the lifting process, thereby improving the safety of the device. The cross screw 51 and the first connecting member 52 are threadedly connected to form a disassembly structure. The threaded connection makes the connection stable, easy to install and disassemble, and can save disassembly time, thereby facilitating installation.

[0037] A fixed wheel 6 is provided at the upper end of the screw rod 1, and a second connecting member 61 is fixed to the upper end of the fixed wheel 6 for connecting with a hook on a crane to facilitate assembly;

[0038] The first steel cable 7 and the second steel cable 8 are arranged around the outer side of the fixed wheel 6, and the end of the first steel cable 7 is woven into a ring, which can be quickly put on the other end of the concrete pole, which is convenient for installation and can limit its position to prevent shaking. Since the length of the first steel cable 7 is shorter than the length of the second steel cable 8, when the crane is lifting, one end of the first steel cable 7 is lifted first, and the center of gravity of the concrete pole is shifted downward to the fixed component 3, so that there is no need to find the balance point multiple times before lifting, which reduces the lifting time and does not require centering when lifting concrete poles of different lengths, which helps to reduce the workload of the staff.

[0039] A support seat 9 is fixed to the right end of the fixing seat 5, and the fixing wheel 6 is fixedly connected to the support seat 9 through the second steel cable 8. The first steel cable 7 and the second steel cable 8 drive the entire device to move upward and lift the concrete pole.

[0040] The following is a further description of a hoisting structure for producing annular concrete poles provided by the utility model in combination with the accompanying drawings and implementation modes.

[0041] When in use, by rotating the nut 2, the rotating shaft 301 is driven to slide in the horizontal direction, and at the same time, the rope telescopic rod 4 is shortened inward, and the connecting rod 302 and the support rod 321 are driven to rotate along the hinge seat 322, and the clamping block 303 is expanded outward until the clamping block 303 is adapted to the diameter of the concrete pole, and the clamping block 303 is clamped on the edge of one end of the concrete pole to fix it, and the ring-shaped end of the first steel cable 7 is sleeved on the other end of the concrete pole. Since the length of the first steel cable 7 is short, When the vehicle is lifted, the end of the concrete pole sleeved with the first steel cable 7 can be lifted first, thereby changing the center of gravity of the concrete pole. When fully lifted, the center of gravity of the concrete pole is shifted to the fixing assembly 3, thereby avoiding the need to find a balance point for the concrete pole. When multiple groups of concrete poles are lifted, another group of devices can be added. By aligning the cross screws 51 of the two groups of devices and tightening the first connecting piece 52 at the connection between the two groups of devices, splicing is performed and the two groups of devices are installed on different concrete poles.
