Description

Technical Field

[0001] This invention belongs to the field of aluminum electrolysis production equipment hoisting technology, specifically relating to an aluminum electrolysis cell upper structure hoisting system and an adjustable hoisting tool, wherein the adjustable hoisting tool is used for hoisting and installing the upper structure of the aluminum electrolysis cell. Background Technology

[0002] The superstructure of an aluminum electrolytic cell is a massive metal frame integrating multiple components such as an anode lifting mechanism, a shell-breaking cylinder, a feeding device, and a gas collection duct. The overall weight of the superstructure is substantial, typically reaching tens of tons. During major overhauls of the electrolytic cell, two overhead cranes are often needed to smoothly lift the superstructure and accurately place it in the corridor. However, due to the fact that the crane hooks on site can only lift vertically and cannot move laterally along the crane, a large angle is created between the wire rope and the lifting point during hoisting, making normal lifting impossible and posing a significant risk of wire rope damage and breakage. Summary of the Invention

[0003] This invention provides a lifting system for the upper structure of an aluminum electrolysis cell and an adjustable lifting device. By setting an adjustment kit between the longitudinal and transverse lifting beams, the device is easy to adjust and reliable in positioning, enabling safe and efficient lifting of the upper structure of the aluminum electrolysis cell.

One longitudinal beam is located on one side of the superstructure in the transverse direction, and the other longitudinal beam is located on the other side of the superstructure in the transverse direction.

[0024] like Figures 1-3 As shown, the adjustable spreader includes two crossbeams, one of which is located on one side of the superstructure in the longitudinal direction, and the other is located on the other side of the superstructure in the longitudinal direction. Each crossbeam is used to pass through the busbar mounting hole of the superstructure to support the superstructure.

[0025] In some embodiments, such as Figure 4 As shown, the middle of the side of the crossbeam facing the upper structure is recessed to form a web; the web serves as a limit to prevent the upper structure from sliding laterally relative to the crossbeam.

[0026] The crossbeam is designed with a recessed middle section on one side as a limit to hold the upper structure in place.

[0027] In some embodiments, the crossbeams are made of stainless steel. Because the electrolysis workshop is a strong magnetic field environment, the crossbeams are made of stainless steel.

[0028] In some embodiments, the crossbeam is welded from steel plates.

[0029] like Figures 1-3As shown, the adjustable spreader includes eight connecting kits and two longitudinal beams, wherein one longitudinal beam is located on one side of the superstructure in the transverse direction and the other longitudinal beam is located on the other side of the superstructure in the transverse direction. The two longitudinal beams are connected to the two transverse beams by the eight connecting kits to support the two transverse beams.

[0030] In some embodiments, the crossbeam has through holes at both ends, wherein the lower part of the connecting kit is locked to the crossbeam through the through holes and a pivot pin; the upper part of the connecting kit has a square hole, wherein the longitudinal beam passes through the square hole to connect to the crossbeam.

[0031] Through holes are provided at both ends of the crossbeam, and the connecting kit is locked onto the crossbeam with a pivot pin; the longitudinal beam passes through the square hole at the top of the connecting kit to connect the two ends of the crossbeam.

[0032] like Figure 5 As shown, the square hole at the top of the connecting kit, also called the connecting longitudinal beam hole, allows the longitudinal beam to be connected, thereby connecting the crossbeam to the longitudinal beam. The connecting kit also has a connecting pin hole at the top. The pin lock secures the connecting kit to the crossbeam through the connecting pin hole and the through hole. In some embodiments, the longitudinal beam is made of H-beam steel, using ordinary steel.

[0033] In some embodiments, the connecting kit is made of stainless steel. Because the electrolysis workshop is a strong magnetic field environment, the connecting kit is made of stainless steel.

[0034] In some embodiments, the pin lock is made of stainless steel. Because the electrolysis workshop is a strong magnetic field environment, the pin lock is made of stainless steel.

[0035] In some embodiments, the connecting kit is made by cutting a steel plate into the designed shape using a laser cutter.

[0036] like Figures 1-3 As shown, the adjustable lifting device includes two sets of adjusting components. One set of adjusting components supports one end of the lower longitudinal beam and connects to a crane hook at the top; the other set of adjusting components supports the other end of the lower longitudinal beam and connects to another crane hook at the top. Each set of adjusting components consists of two adjusting components.

[0037] Each adjusting component can slide along the longitudinal beam according to the position of the hook to adjust the relative position between the superstructure and the crane hook.

[0038] Four of the eight connecting kits are threaded onto one longitudinal beam, and the other four are threaded onto another longitudinal beam. Each longitudinal beam has four connecting kits, two on each side. An adjusting hanger is fitted onto each end of the longitudinal beam.

[0039] like Figure 6As shown, the adjusting lifting component is provided with a connecting longitudinal beam hole and a lifting hole, wherein the connecting longitudinal beam hole is for the longitudinal beam to pass through, and the lifting hole serves as a lifting lug connected to the hook. For example, the connecting longitudinal beam hole is square, and the lifting hole is elliptical.

[0040] The adjusting lifting components are located at both ends of the longitudinal beam. The lifting components have two holes: a square hole for the longitudinal beam to pass through, which can slide along the longitudinal beam according to the position of the hook, and an oval hole as a lifting lug connected to the hook.

[0041] In some embodiments, the adjusting suspension components are made of stainless steel. Because the electrolysis workshop is a strong magnetic field environment, the adjusting suspension components are made of stainless steel.

[0042] In some embodiments, the adjusting hanger is formed by cutting a steel plate into the designed shape using a laser cutting machine.

[0043] When assembling or preparing the adjustable lifting device, first thread the connecting kits onto the longitudinal beams, with four connecting kits on each beam (two on each side). Then, attach one adjusting lifting element to each end of the longitudinal beam. Finally, seal both ends of the longitudinal beam with steel plates to prevent the kits from slipping. Next, place the crossbeam through the busbar hole in the appropriate position, aligning the lower circular hole of the connecting kit with the circular hole at the end of the crossbeam, and lock it in place with a pivot pin. Finally, insert the hook into the lifting hole of the adjusting lifting element for lifting.
