AI Technical Summary
The existing method of hoisting switchgear results in excessive stress points on the casing, which can easily damage the casing and cause paint peeling, affecting the appearance quality.
A combined lifting mechanism of side boom and top boom is adopted. The switch cabinet housing is limited by electric push rods and limit devices to reduce direct contact of wire ropes. The housing is lifted stably by electric push rods and limit plates.
This reduces the chance of damage to the shell surface, ensures the safety and stability of the hoisting process, and avoids damage to the shell's stress points and paint peeling.

TECHNICAL FIELD
[0001] The utility model relates to hoisting equipment technical field, especially a switch cabinet hoisting mechanism. BACKGROUND
[0002] The switch cabinet is a kind of electrical equipment, mainly used in the power generation, power transmission, power distribution and electric energy conversion process of power system, with the function of opening and closing, control and protection of electrical equipment. The main components in the switch cabinet include the shell and the circuit breaker, disconnecting switch, load switch, operating mechanism, transformer and various protection devices installed in the shell.
[0003] In the production of switch cabinet, it will involve the process of hoisting to different workstations by sky crane (such as hoisting the switch cabinet product into the vehicle box, or hoisting into the warehouse at the side end of the production area, etc.). The existing switch cabinet hoisting method is generally to pass two steel wires through the middle of the switch cabinet from the lower end, and then hook the upper ends of the two steel wires at the hooks of the sky crane, so that the sky crane hoists the switch cabinet to the relevant position. Although the existing sky crane with steel wire hoisting method meets the hoisting needs to some extent, it is still affected by the hoisting equipment and the hoisting method, and there are still the following technical defects. Specifically, the steel wire hoisting switch cabinet, since the hoisting is away from the ground, the weight of the switch cabinet is entirely applied to the steel wire, and the force point of the switch cabinet shell in contact with the steel wire is relatively large, and there is a risk of excessive force on the force point of the switch cabinet shell and the steel wire (especially for the sky crane driver with poor skills, the sky crane runs unstably and shakes relatively large, which increases the risk of damage to the switch cabinet shell caused by the concave defect). In addition, the contact point between the steel wire and the shell of the switch cabinet is prone to paint peeling due to the influence of steel wire friction, which adversely affects the appearance quality of the switch cabinet. Due to the above factors, it is necessary to provide a switch cabinet hoisting mechanism that can reduce the damage probability of the shell surface of the switch cabinet. SUMMARY
[0004] In order to overcome the disadvantages of the existing switch cabinet due to the use of single steel wire hoisting method, the utility model provides a switch cabinet hoisting mechanism under the joint action of related mechanisms, which allows ground workers to conveniently control the contact of two side hoisting arms with the two side ends of the shell of the switch cabinet, the lower ends of the two side hoisting arms to limit the left and right sides of the lower end of the switch cabinet, and the front and rear end limiting plates of the upper hoisting arm to limit the front and rear sides of the upper end of the shell of the switch cabinet. Since the area of the side hoisting arm in contact with the shell is relatively large, and the force is applied by the lower end of the side hoisting arm and the shell, the probability of damage to the surface of the shell is reduced, and the safety and stability of the switch cabinet during hoisting are ensured.
