Description

Technical Field

[0001] The utility model relates to the technical field of lifting tools, in particular to a lifting clamp for a graphite cylinder body of a synthetic furnace. Background Art

[0002] In the existing industrial production, the chlor-alkali section occupies an important position, and the hydrogen chloride synthesis furnace is a key device in the chlor-alkali section. At present, to ensure the service life of the hydrogen chloride synthesis furnace, its structure is generally a jacketed design, with a steel shell on the outside and a graphite cylinder body on the inside. The hydrogen chloride synthesis furnace with a graphite cylinder body is generally divided into three sections: the lower combustion section, the middle combustion section, and the cooling section. The service life of the cooling section can generally exceed ten years, while the service life of the lower combustion section is less than half of that of the cooling section. To save costs, the graphite cylinder body of the lower combustion section is generally replaced. When replacing the graphite cylinder body, generally, the steel shell is first lifted and removed, and then the internal graphite cylinder body is lifted in sections. In the prior art, the graphite cylinder body is generally lifted by using a method of tying with two slings; that is, two slings of the same length are used to surround the graphite cylinder body for tying, and a shackle is used to connect to a single sling hanging on the crane hook for lifting. When using the slings to bundle and lift the graphite cylinder body: because a waterproof adhesive layer is applied on the surface of the graphite cylinder body, it is easy to slip after being lifted, causing personal injury or damage to the graphite cylinder body; moreover, the slings are flexible and have a certain elasticity after being lifted, resulting in uneven stress on the graphite cylinder body; the shackle part is easy to scratch the waterproof layer on the surface of the graphite cylinder body; and the position where the slings are tied will have a slight deviation when lifted, causing the graphite cylinder body to be lifted unevenly or obliquely, affecting the installation efficiency and safety.

Preferably, the first flexible anti-slip pad 4 is a rubber block with wires or a belt, which is convenient to obtain materials and will not cause pollution. Tooth-shaped protrusions 1 are evenly distributed inside the first flexible anti-slip pad 4 to increase the local pressure on the cylinder, thereby increasing the friction force.

[0044] In the combined structure of the first support body 1 and the first flexible anti-slip pad 4, the cross-section at the position of the tooth-shaped protrusion 1 is trapezoidal with a wide upper end and a narrow lower end. When an upward pulling force is applied to the first support body 1, due to the inclination of the first support body 1, there will be an inward radial force, thereby increasing the pressure exerted by the first support body 1 on the first flexible anti-slip pad 4, and at the same time increasing the friction force between the first flexible anti-slip pad 4 and the graphite cylinder to prevent the graphite cylinder from slipping during lifting.

[0045] A flexible anti-slip pad II (5) is fixedly arranged on the inner side of the second support body (2); to increase the friction force and prevent the cylinder body from slipping and scratching the cylinder body. Preferably, the flexible anti-slip pad II (5) is a wire-rubber block or a leather belt, which is convenient to obtain materials and will not cause pollution. Tooth-shaped protrusions II are evenly distributed on the inner side of the flexible anti-slip pad II (5) to increase the local pressure on the cylinder body, thereby increasing the friction force; in the combined structure of the second support body (2) and the flexible anti-slip pad II (5), the cross-section at the position of the tooth-shaped protrusions II is trapezoidal with a wider upper end and a narrower lower end; when the second support body (2) is subjected to an upward pulling force, due to the inclination of the second support body (2), there will be an inward radial force, which will increase the pressure exerted by the second support body (2) on the flexible anti-slip pad II (5), and at the same time increase the friction force between the flexible anti-slip pad II (5) and the graphite cylinder body, preventing the graphite cylinder body from slipping during hoisting. One end of the second support body (2) is connected to one end of the first support body (1) through a pin shaft I (10); the second support body (2) can swing relative to the first support body (1) to open and close, wrap or release the graphite cylinder body.

[0049] When the other end of the third support 3 is connected to the other end of the second support 2, the first support 1, the second support 2, and the third support 3 form a frustum-shaped cylindrical structure with a larger diameter at the upper end and a smaller diameter at the lower end; the first support 1, the second support 2, and the third support 3 form an upwardly open support structure.
