Description

Technical Field

[0001] The utility model relates to the technical field of lifting equipment, in particular to a tobacco frame elevator. Background Art

[0002] Tobacco flue-curing requires hanging tobacco leaves on tobacco racks, which are then hung on racks within the flue-curing room. Conventional flue-curing rooms have fixed poles that cannot be raised or lowered, requiring manual labor to operate at height. Some newer flue-curing rooms have internal lifting mechanisms to elevate the poles, but the tobacco leaves in a flue-curing room can weigh several tons, placing high demands on these mechanisms and requiring improvements. Utility Model Content

[0003] In order to solve the problems mentioned in the background technology, the purpose of the present invention is to provide a tobacco frame elevator.

[0004] In order to achieve the above objectives, the technical solution of the utility model is:

[0005] The lifting mechanism is a kind of inertia of the present invention, and its first end is connected with the 3rd part of the 4th part to the 5th part, and the last part is connected with the 3rd part to the 5th part, and the last part is connected with the 3rd part to the 5th part.

[0006] The beneficial effects of the present invention are as follows: the tobacco frame is placed between two opposite top poles or two opposite lower poles, and the rotating shaft is driven by a motor to rotate, so that the tobacco frame can be lifted. Since a movable pulley is provided, the lifting force can be reduced by half, thereby reducing the requirements for the motor. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

[0012] like Figure 1-Figure 3 As shown, a tobacco frame hoist comprises a rectangular frame 1, which is horizontally arranged at the top of the tobacco flue-curing room. Columns 11 are connected to the four corners of the frame 1, and the columns 11 are fixed to the ground. A shaft 2 is horizontally arranged below the two long sides of the frame 1. The two shafts 2 are parallel to the two long sides of the frame 1. Three movable pulleys 3 are rotatably sleeved on the shaft 2. The three movable pulleys 3 are arranged along the axial space of the shaft 2. A rotating shaft 4 is horizontally installed between every two columns 11 spaced apart along the long sides of the frame 1. The rotating shaft 4 is arranged above the shaft 2, and the rotating shaft 4 corresponds to three shafts close to itself. The movable pulley 3 is wrapped with three traction ropes 5, one end of the traction ropes 5 is fixed on the rotating shaft 4, and the other ends of the three traction ropes 5 are respectively passed around three adjacent movable pulleys 3 and fixed on the long side of the frame 1. Motors 6 for driving the two rotating shafts 4 to rotate are respectively installed on the columns 11. Both ends of the shaft 2 are connected to the suspension rods 7. The bottom ends of the two suspension rods 7 connected to the same shaft 2 are commonly connected to a top spanning rod 8. Two lower spanning rods 9 are arranged at intervals in the longitudinal direction below each top spanning rod 8. Multiple connecting ropes 10 are connected between two adjacent lower spanning rods 9 and between adjacent top spanning rods 8 and lower spanning rods 9.

[0013] In actual application, the tobacco frame is placed between two opposite top rods 8 or two opposite lower rods 9, and the rotating shaft 4 is driven by the motor 6 to rotate, so that the tobacco frame can be lifted. Since a movable pulley 3 is provided, the lifting force can be reduced by half, thereby reducing the requirements for the motor 6.

[0014] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. All modifications, equivalent replacements, improvements, etc. within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
