Description

Technical Field

[0001] This utility model belongs to the field of cement pole technology, specifically relating to a lifting device for cement pole production. Background Technology

[0002] Cement poles are hollow, precast columnar components made with reinforced steel as the reinforcing skeleton and concrete as the main matrix material, manufactured through processes such as centrifugal molding and steam curing. Their core function is to serve as a supporting structure for overhead power, communication, railway, and municipal lighting lines, bearing the conductors, insulators, hardware, and external loads to ensure the safe and stable transmission of energy and information. They are classified by structure into prestressed and non-prestressed poles, and by shape into tapered and equal-diameter poles. They offer advantages such as high strength, durability, corrosion resistance, and low maintenance costs, but suffer from disadvantages such as being heavy and inconvenient to transport. They are backbone components of modern power grids and urban infrastructure.

[0003] One of the proposed lifting devices for cement pole production, with announcement number CN222907338U, involves connecting a lifting rope to an external crane. The clamping frame is positioned outside the pole body. Rotating the adjusting rod moves the limiting frame outwards. This outward movement of the limiting frame, via the pressing connecting rollers, causes the connecting frame to move downwards. During this downward movement, the adjusting rod moves the clamping frame inwards, clamping and securing the pole body for subsequent lifting. However, this method requires the cement pole to be moved to an unobstructed location to facilitate the opening and closing of the clamping frame and its clamping function. However, most cement poles are stacked to save space, making it inconvenient to lower the clamping frame to the left and right sides, thus limiting the usability of this method. Utility Model Content

[0004] To address the limitation of application scenarios in the existing technology, this utility model provides a lifting device for cement pole production. It employs a clamping structure to fix both ends of the cement pole. Compared to existing technologies that clamp the side walls of the cement pole, this device's method of clamping both ends is more convenient to use. The specific technical solution is as follows: A lifting device for cement pole production includes: a cement pole body; a clamping structure is movably installed on the outside of the cement pole body; a balancing structure is movably installed on the outside of the clamping structure; and a lifting structure is installed on the upper wall of the balancing structure. The clamping structure includes: two clamping seats, two clamping rotating seats, and a clamping lifting rope; the two clamping seats are respectively movably installed at both ends of the cement pole body; the two clamping rotating seats are respectively installed on the upper wall of the clamping seats; and the clamping lifting rope is installed between the two clamping rotating seats.

[0005] Preferably, the balancing structure includes: a balancing roller, a balancing roller frame, and a balancing tension cable; the balancing roller is movably installed below the clamping hoisting rope, the balancing roller frame is movably installed outside the balancing roller via a shaft, and one end of the balancing tension cable is installed on the upper wall of the balancing roller frame.

[0006] Preferably, the hoisting structure includes: a hoisting connecting ring, a hoisting belt, and two hoisting pull rings; the hoisting connecting ring is fixedly installed at the upper end of the balance tension cable, the hoisting belt is movably installed in the hoisting connecting ring, and the two hoisting pull rings are respectively installed at both ends of the hoisting belt.

[0007] Preferably, the two clamping seats include: a clamping fixing seat and three clamping fixing rods; the clamping fixing seat is installed on the lower wall of the clamping rotating seat, and the three clamping fixing rods are respectively installed on the side wall of the clamping fixing seat, two of the clamping fixing rods are located outside the cement pole body, and one of the clamping fixing rods is located inside the outside of the cement pole body.

[0014] The following are specific implementation cases and appendices. Figures 1-4 This utility model will be further described below, but it is not limited to these embodiments. This utility model provides a technical solution: a lifting device for cement pole production, comprising: a cement pole body 1, a clamping structure movably mounted on the outside of the cement pole body 1, a balancing structure movably mounted on the outside of the clamping structure, and a lifting structure mounted on the upper wall of the balancing structure; the clamping structure includes: two clamping seats 2, two clamping rotating seats 3, and a clamping lifting rope 4; the two clamping seats 2 are respectively movably mounted at both ends of the cement pole body 1, and the two clamping rotating seats 3 are respectively mounted on the clamping seats 2. The upper wall surface of the clamping and hoisting rope 4 is installed between two clamping rotating seats 3. The two clamping seats 2 include: clamping fixing seat 201 and three clamping fixing rods 202; the clamping fixing seat 201 is installed on the lower wall surface of the clamping rotating seat 3, and the three clamping fixing rods 202 are respectively installed on the side wall surface of the clamping fixing seat 201. Two clamping fixing rods 202 are located outside the cement pole body 1, and one clamping fixing rod 202 is located inside the outside of the cement pole body 1. The three clamping fixing rods 202 are provided with anti-slip rubber sleeves 11 on the outside, and a limiting rope 12 is provided between the two clamping rotating seats 3.

[0015] As a preferred embodiment, the balancing structure further includes: a balancing roller 5, a balancing roller frame 6, and a balancing tension cable 7; the balancing roller 5 is movably installed below the clamping hoisting rope 4, the balancing roller frame 6 is movably installed on the outside of the balancing roller 5 via a shaft, one end of the balancing tension cable 7 is installed on the upper wall of the balancing roller frame 6, the balancing roller 5 is provided with an anti-slip flange, and the balancing roller 5 is provided with several weight-reducing holes.

[0016] As a preferred embodiment, the hoisting structure further includes: a hoisting connecting ring 8, a hoisting belt 9, and two hoisting pull rings 10; the hoisting connecting ring 8 is fixedly installed at the upper end of the balance tension cable 7, the hoisting belt 9 is movably installed in the hoisting connecting ring 8, and the two hoisting pull rings 10 are respectively installed at both ends of the hoisting belt 9.

[0017] Working principle: When using this device, the operator uses two lifting rings 10 to fix the device in the lifting equipment, thus completing the installation and fixation of the device.

[0018] The operator inserts two sets of three clamping rods 202 into the concrete pole body 1. Two of the three clamping rods 202 are located on the outside of the concrete pole body 1, while one clamping rod 202 is located inside the concrete pole body 1. The three clamping rods 202 are equipped with anti-slip rubber sleeves 11 to provide greater friction between the clamping rods 202 and the concrete pole body 1. Two clamping seats 201 are respectively secured to both ends of the concrete pole body 1. Simultaneously, the operator uses a shaft to fix both ends of the limiting rope 12 to the side wall of the clamping seats 201, thereby preventing the distance between the two clamping seats 201 from increasing and ensuring that the concrete pole body 1 will not fall off under the fixation of the two clamping seats 2.

[0019] Next, the lifting process begins. The lifting equipment is used to lift the pole by using two lifting rings 10 to drive the lifting belt 9 and the lifting connecting ring 8, thereby raising the balance cable 7. The balance cable 7 drives the balance roller frame 6 to rise, which in turn drives the balance roller 5 to rise via a movable shaft. At this time, the clamping lifting rope 4 rolls relative to the outside of the balance roller 5 until the center of gravity of the concrete pole body 1 and the balance roller 5 are on the same vertical line. Then, the operator uses the shaft to fix the balance roller 5 and the balance roller frame 6 relative to each other. The outside of the balance roller 5 is frosted, and the outer surface of the balance cable 7 is covered with a non-slip outer skin. After the concrete pole body 1 is installed, the friction between the clamping lifting rope 4 and the balance roller 5 can prevent relative slippage between them.

[0020] Then, the balancing tension cable 7 drives the two clamping seats 2 to lift the cement pole body 1 upwards. The clamping fixing seat 201 and the three clamping fixing rods 202 clamp the cement pole body 1 upwards, thus completing the transportation. Since this device clamps both ends of the cement pole body 1, it is convenient to fix and transport the cement pole body 1 even if it is on the ground.
