Description

Technical Field

[0001] This utility model relates to the field of hoisting machinery and equipment technology, specifically to a high-safety hoisting flip-plate device. Background Technology

[0002] Hydraulic tilting devices are widely used in hoisting operations in steel plant areas. They provide a load-bearing platform for hoisting operations, are driven, are very easy to operate, and have a relatively high safety factor, making them very suitable for hoisting operations.

[0003] At the hoisting port on the fifth floor of the 300 sintering machine, the boundary between the hoisting ports on the sixth and fifth floors is directly opposite. Due to this spatial limitation, the crane hook on the sixth floor cannot be vertically lowered onto the platform for hoisting when it passes through the hoisting port to the fifth floor platform. Instead, the crane hook must be pulled at an angle to lift the object, which is very troublesome and inefficient. In addition, if the hoisting goes out of control during hoisting, the object hanging on the hook may fall onto the workers, causing a safety accident.

[0004] The main ideas and shortcomings of existing methods are as follows: (1) Method 1: Each time a hoisting operation is performed, a crane or other lifting machinery is used to place the hoisting hole cover plate on the hoisting hole. After the hoisting is completed, the crane or other lifting machinery is used again to lift the cover plate away from the hoisting hole area. This not only increases the labor intensity and operational difficulty for workers, but also wastes hoisting machinery resources. If other maintenance within the factory area also requires the use of cranes or other lifting machinery, there will be competition for cranes, affecting the progress of maintenance within the factory area, and thus adversely affecting production. (2) Method 2: A self-made tilting platform is installed at the hoisting hole. This platform can be tilted using a hand-operated hoist. However, hand chain hoists have certain limitations. Their braking performance is unreliable because, under the weight of the load, the lifting chain wheel attempts to rotate in the opposite direction. The five-tooth long shaft drives the hand chain wheel, friction plate, and ratchet to tighten again, and the pawl engages with the ratchet to achieve braking. However, if problems such as severe wear of the friction plate, overloading of the load, loosening of the pawl spring, or chain jamming occur, the hand chain hoist's braking function will fail, and the load will drop directly, easily leading to safety accidents. In addition, there is a hand chain hoist on each side of the flipping device. When flipping, two people need to pull the hand chain hoists simultaneously, which wastes a lot of manpower. Utility Model Content

[0005] The purpose of this invention is to provide a highly safe hoisting and flipping device to address the shortcomings of existing technologies.

[0006] The technical solution of this utility model to solve the above problems is: a high-safety hoisting and flipping device, including a hoisting mechanism and a flipping mechanism;

[0009] Furthermore, the two sets of tilting devices include a winch drum, a frame, and a transmission mechanism. The transmission mechanism includes a steel wire rope, a first transmission roller, and a second transmission roller. The inner end of the steel wire rope is wound on the winch drum, and the outer end passes through the first transmission roller and the second transmission roller in sequence to connect with the outer end of the tilting platform. The first transmission roller is fixedly connected to the bottom plate of the lower layer of the sintering chamber, and the second transmission roller is fixedly connected to the top of the frame.

[0010] Furthermore, the edge of the flip platform is equipped with a guardrail, and ear plates are provided on both sides of the outer end of the guardrail, with the outer ends of two steel wire ropes respectively tied to the two ear plates.

[0011] Furthermore, the lifting mechanism includes a crane body and a traveling rail, with the crane body slidably and adjustablely connected to the traveling rail. The traveling rail is fixedly connected to the bottom of the upper top layer plate of the sintering chamber, and the outer end of the traveling rail extends outward beyond the upper top layer plate of the sintering chamber.

Detailed Implementation

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] As shown in the figure, a high-safety hoisting and flipping device includes a hoisting mechanism and a flipping mechanism;

[0020] The lifting mechanism includes a crane body 1 and a traveling rail 2. The crane body 1 is slidably and adjustablely connected to the traveling rail 2. The traveling rail 2 is fixedly connected to the bottom of the upper top plate 3 of the sintering chamber, and the outer end of the traveling rail 2 extends outward beyond the upper top plate 3 of the sintering chamber.

[0021] The flipping mechanism includes a flipping platform 5 and two sets of flipping devices. The inner end of the flipping platform 5 is hinged to the bottom plate 4 of the lower layer of the sintering chamber, and the edge of the flipping platform 5 is provided with a guardrail 6. The two sets of flipping devices include a winch drum 7, a frame 8, and a transmission mechanism. The transmission mechanism includes a wire rope 9, a first transmission roller 10, and a second transmission roller 11. The inner end of the wire rope 9 is wound on the winch drum 7, and the outer end passes through the first transmission roller 10 and the second transmission roller 11 in sequence to connect with the outer end of the guardrail 6. The two sides of the outer end of the guardrail 6 are respectively provided with ear plates 12, and the outer end of the wire rope 9 is tied to the ear plates 12. The first transmission roller 10 is fixedly connected to the bottom plate 4 of the lower layer of the sintering chamber, and the second transmission roller 11 is fixedly connected to the top of the frame 8.

[0022] The frame 8 is fixedly installed at the outermost end of the lower layer plate of the sintering chamber.

[0023] The winch drum 7 is driven by a hydraulic motor, which is driven by a hydraulic oil system.

[0024] like Figure 1 As shown, the original method of hoisting the load 13 from the lower level of the sintering chamber to the upper level of the sintering chamber was to use an oblique hoisting method. There was a risk that the load 13 could be thrown out, causing personnel injury.

[0025] like Figure 2 As shown, when using this device for hoisting, the two sets of tilting devices flatten the tilting platform 5, a forklift is used to transport the load 13 onto the tilting platform 5, and then the crane body 1 is used to vertically lift the load 13. Finally, the crane body 1 slides inward along the trolley rail 2 to unload the load 13 to the upper layer of the sintering chamber. Then the two sets of tilting devices fold the tilting platform 5 back up.
