Description

Technical Field

[0001] The utility model relates to the technical field of vehicle body pre-treatment electrophoresis and coating transportation, in particular to an automatic conversion control system for a ground-to-air hoist. Background Art

[0002] In large-scale automobile painting, assembly and other production fields, the transportation of car bodies needs to be transferred from ground conveyor carriers to aerial conveyor slings. After completing different process operations, the car body on the aerial sling needs to be automatically transferred to the ground conveyor carrier. The transfer of ground-to-air slings requires many actions, including linear movement of the main machine and sling, lifting and lowering, stopping, positioning, clamping, rotation, opening and closing, and other multi-dimensional actions. At present, during the ground-to-air conversion, due to the weight of the car body, the ground-to-air track is prone to deviation during docking. Therefore, we propose an automatic conversion control system for ground-to-air slings to solve the above problems. Utility Model Content

[0003] The utility model aims to solve the shortcomings in the prior art and proposes an automatic conversion control system for a ground-to-air sling.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A control system for automatic conversion of ground-to-air hoists comprises a frame, a ground rail is arranged at the lower end of the frame, a ceiling rail is arranged at the upper end of the frame, a trolley is arranged on the ground rail, a support frame is arranged at one end of the ground rail close to the ceiling rail, the support frame is fixed on the ground rail, and docking rods are slidably installed on both sides of the support frame, the upper ends of the docking rods are slidably connected to the ceiling rails, and the bottom ends of the docking rods are arranged with hydraulic cylinders.

[0006] As a preferred technical solution of the utility model, multiple groups of pulleys are provided on the ground rail and the ceiling rail, the pulleys are arranged linearly, and the distance between two adjacent groups of pulleys is less than the length of the cart, and the cart is supported by the pulleys.

[0007] As a preferred technical solution of the utility model, guide bars matched with the pulleys are arranged on both sides of the cart to limit the movement of the cart and prevent it from being separated from the ground rail.

[0008] As a preferred technical solution of the utility model, a matching snap-in seat is provided at one end of the ground rail and the ceiling rail close to each other, and the stability of the ground rail and the ceiling rail when docking is further improved through the cooperation of the snap-in seat.

[0009] As a preferred technical solution of the utility model, a roller is installed on the top of the docking rod, and a sliding groove matched with the roller is opened on the ceiling rail to improve the sliding stability of the docking rod on the ceiling rail.

[0010] The beneficial effects of the utility model are:

[0011] During the docking process between the ground rail and the ceiling rail, the docking rod is driven to move on the ceiling rail at the same time, and the docking rod applies a certain upward pulling force to the end of the ground rail close to the ceiling rail, thereby reducing the factor of the downward deviation of the end of the ground rail and improving the stability of the docking between the ground rail and the ceiling rail.
