Description

Technical Field

[0001] The utility model relates to the field of aviation technology, and more specifically to a long cylinder hoisting and rolling integrated device. Background Art

[0002] During the assembly of large special cylinders, there are often cylinder hoisting and cylinder rolling operations. When the product (cylinder section) needs to be hoisted and axially rolled at the same time, a special transfer station is required for rolling.

[0003] Conventional operation: The cylinder section is transported to the work station, hoisted and placed on the construction table. After one side is processed on the construction table, it is hoisted and transported to the transfer station for rolling. After rolling 180 degrees, it is hoisted and placed on the construction table of the work station for operation, and then transported out after completion.

[0004] The whole process requires multiple lifting and lowering, changing two workstations, and tedious manual operations for tooling removal. In actual processing, large-diameter barrel sections are often heavy and large in size, and the handling process and tooling removal take a long time, and there are certain safety hazards. Utility Model Content

[0005] The purpose of the utility model is to provide a long cylinder hoisting and rolling integrated device which can reduce the intermediate links in the process of hoisting and rolling of large diameter and long length cylinder sections and improve the working efficiency in view of the shortcomings of the existing technology.

[0006] An integrated device for hoisting and rolling of a long cylinder includes a hoist body, the hoist body is provided with a suspension hoist for hoisting, the left and right sides of the hoist body are respectively provided with rotating mechanisms for rolling products, a power mechanism is provided between the two rotating mechanisms for inputting power; the rotating mechanism includes two rotating wheel assemblies in the front and rear directions, the two rotating wheel assemblies are connected by a chain, and the latches on the outer sides of the two rotating wheel assemblies are provided with connected rolling belts; the power mechanism includes a power shaft, the power shaft is provided with a reducer, which is used to convert the rolling belt from full roll to empty roll on the two rotating wheel assemblies to drive the rolling of the product. The utility model has a reasonable structure and improves the utilization rate of the workshop space: the hoisting and rolling processes are completed in the same process, and no intermediate transfer station is required. The more stations there are, the more transfer stations are reduced. The labor intensity of employees is reduced; and the efficiency is improved.

[0007] As a further improvement and supplement to the above solution, the utility model also includes the following additional technical features:

[0008] The rotating wheel assembly comprises a short shaft, a roller sleeved on the short shaft, baffles on both outer sides of the roller, and a sprocket on the outer side of one baffle. The structure is reasonable and reliable.

[0009] The long cylinder hoisting and rolling integrated device also includes an anti-collision mechanism, which includes handrails and handrail covers arranged on both sides, thereby reducing potential safety hazards and ensuring safety.

[0010] Anti-falling straps are also provided on both outer sides of the sling body, which further increases the safety of the operation process.

[0011] The two outer sides of the rotating wheel assembly are respectively provided with seat bearings, which effectively provide support and ensure the service life of the rotating wheel assembly.

[0012] The reducer is provided with a hand wheel, which is convenient to operate and has a simple and reasonable structure.

[0013] The long cylinder hoisting and rolling integrated device also includes a bracket arranged at the lower side, which can be used for placing and rotating products.

[0014] A cover is arranged on the outer side of the chain, which effectively protects the chain from damage and ensures the safety of personnel.

[0015] The following beneficial effects can be achieved by using the utility model:

[0016] Improve the utilization rate of workshop space: the lifting and rolling processes are completed in the same process, and no intermediate transfer stations are required. The more stations there are, the more transfer stations can be reduced.

[0017] Optimize the process flow and improve the automation level of the workshop: Due to the reduction of workstations and manual participation, more processes can be involved in automated production. For example, during transportation, it can cooperate with AGV vehicles and their dispatching systems.

[0018] Reduce personnel input: reduce the number of personnel responsible for rolling stations.

[0019] It reduces the labor intensity of employees, improves efficiency, and reduces safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The long cylinder hoisting and rolling integrated device described in this embodiment includes a hoisting device body 15, and the two sides of the hoisting device body 15 are arranged with cantilevers at intervals. The hoisting device body 15 is provided with a suspension hoist 14 for hoisting, and the left and right sides of the hoisting device body 15 are respectively provided with a rotating mechanism for rolling the product 7, and a power mechanism is provided between the two rotating mechanisms for inputting power; the rotating mechanism includes two rotating wheel assemblies 3 in the front and rear directions, the rotating wheel assemblies 3 are sleeved on the cantilever, the two rotating wheel assemblies 3 are rotatably connected through a chain 10, and the connecting rolling belts 2 are sleeved on the pins 22 outside the two rotating wheel assemblies 3; the power mechanism includes a power shaft 18, and the power shaft 18 is provided with a reducer 12, which is used to convert the rolling belt 2 from full roll to empty roll on the two rotating wheel assemblies 3 to drive the rolling of the product 7. One side of the reducer 12 is fixed to the hoisting device body 15 by a bracket 13 to strengthen the structure.

[0032] Furthermore, the rotating wheel assembly 3 includes a short shaft 21, a roller 20 sleeved on the short shaft 21, the roller 20 is a hollow structure, baffles 4 on both sides of the roller 20, a sprocket 5 on the outside of one side of the baffle 4, and the two sprockets 5 are connected by a chain 10. The short shaft 21 and the power shaft 18 are connected by a coupling 19, and a rolling belt 2 is sleeved on the pin 22 on the outside of the roller 20.

[0033] Furthermore, the long cylinder hoisting and rolling integrated device also includes an anti-collision mechanism, which includes handrails 9 and handrail covers 11 arranged on both sides. The handrails 9 are fixed on the outside of the sling body 15, and the handrail cover 11 is sleeved in the middle of the handrails 9.

[0034] Furthermore, anti-falling slings 1 are provided on both outer sides of the sling body 15 , and the lifting ears at both ends of the anti-falling slings 1 are inserted into the sling body 15 by fixing pins.

[0035] Furthermore, the two outer sides of the rotating wheel assembly 3 are respectively provided with seat bearings 8. The seat bearings 8 are fixed on the cantilever of the sling body 15, and the sprocket 5 is arranged on the outer side of the seat bearings 8.

[0036] Furthermore, the reducer 12 is provided with a hand wheel 16 for controlling the reducer 12 .

The lifting ear at one end of the rolling belt 2 is inserted into the outer plug pin 22; the lifting ear at the other end is fixed to the rotating wheel assembly 3 in the same way. The state of the rolling belt 2 being wound around the rotating wheel assembly is: one end is fully rolled and the other end is empty. The lifting ears at both ends of the anti-falling sling 1 are inserted into the fixed pins of the sling body 5.
