Description

Technical Field

[0001] The invention relates to the technical field of hoisting of building panels, in particular to a hoisting device for producing purification panels. Background Art

[0002] Purification board is a new type of environmentally friendly building board, also called clean board. It is generally a composite board with color steel plate or stainless steel plate as the surface material and polyurethane, rock wool and other materials as the core material. It has dustproof, antibacterial, antistatic and other characteristics. It is mostly used in the construction of pharmaceutical factories, food processing plants, operating rooms, laboratories and many other fields with high requirements for hygiene and cleanliness. Purification board needs to be hoisted and transported during production and use, and corresponding board hoisting equipment is required at this time;

[0003] For example, the publication number is: CN205892535U, and the patent name is: A patent for a wall panel lifting mechanism, which includes a lifting claw assembly connected to a lifting body through a connecting column, a rotating body arranged on the lifting body and connected to the connecting column, and a vertical correction assembly arranged on the connecting column and used in conjunction with the rotating body; however, the positioning effect of the above device is poor when in use. During the lifting process, the wall panel is easily affected by external forces and produces large shaking, which is highly dangerous.

[0004] In addition, the publication number is: CN219341437U, and the patent name is: A patent for multi-angle positioning wall panel production hoisting equipment. This patent moves the connecting plate to the position of the wall panel by retracting and extending the crane chain, and then starts the motor. The motor drives the long pin to rotate through the first bevel gear and the second bevel gear, and then the long pin drives the column to move toward the center position of the connecting plate through the movable block. Finally, the limit plate clamps the right-angle edge of the wall panel. The limit plates on all four sides ensure the stability of the clamping and avoid the risks caused by shaking during the hoisting process.

[0005] However, when in use, the above device can only fix the plate by squeezing it toward the center through multiple columns and limit plates. This method requires a complex transmission structure, a complex operation process and a high failure rate. In addition, the use of this clamping and fixing method that converges toward the center requires a larger frame as a carrier to implement the opening and closing actions. This large-size frame has a great impact on the convenience and efficiency of hoisting, and cannot meet the company's efficient and stable production and use needs.

[0030] In Example 1 of the present application, the hanging unit includes a lever 13, a connecting rope 14, a limit block 15 and a rotating shaft 16, wherein one end of the hanging unit includes the lever 13, the limit block 15 and one end of the connecting rope 14, and the other end of the hanging unit includes the other end of the connecting rope 14 and the rotating shaft, the lever 13 is located in the fixed cylinder 6, one end of the lever 13 is movably connected to the inner surface of the fixed cylinder 6 through a pin shaft, the lever 13 can swing up and down around the pin shaft, the limit block 15 is installed on the inner surface of the fixed cylinder 6, the limit block 15 is located above the lever 13, and the limit block 15 can block the lever The rod 13 swings upward around the pin and ensures that the angle between the lever 13 and the inner surface of the fixed cylinder 6 above the pin is not less than forty-five degrees.

[0034] During the implementation of this technical solution, those skilled in the art need to connect all electrical components in this case to their adapted power supplies through wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle of this technical solution and the working sequence between the electrical components. The detailed connection means are well-known technologies in this field. This technical solution mainly introduces the working principle and process, and no longer explains the electrical control.

[0035] During the implementation of the technical solution of the present application, the lower surface of the purification board needs to be separated from the bottom surface or the upper surface of other purification boards by a pad. When the purification board needs to be hoisted, the staff operates the hoist 1 with the frame 3 to move to the top of the purification board. At this time, the state of the entire hoisting device is as follows: Figure 1As shown, the staff controls the lifting device 1 to be lowered until the baffle 17 is aligned with the gap separated by the cushion block. At this time, the purification board is placed in the purification board lifting area. Then, the linear motor 9 is started by the remote control switch 7.

At this time, the driving body 12 toggles the lever 13 to swing downward, and one end of the connecting rope 14 is pulled by the other end. The other end of the connecting rope 14 pulls the rotating shaft 16 to perform a positive rotation action. The other end of the baffle 17 is transferred into the purification board lifting area and blocks the lower surface of the purification board. The lifting rod 10, the driving body 12 and the pressing plate 11 continue to press down until the pressing plate 11 presses to the upper surface of the purification board. The state of the entire device is as shown in FIG. Figure 2 As shown, at this time, the pressure plate 11 and the baffle plate 17 form a clamping and fixing state for the purification plate, and the staff controls the lifting device 1 to rise, and lifts and transports the clamped and fixed purification plate to the designated location.

[0036] When the purification panel is hoisted and transported to the designated position, the staff controls the sling 1 to descend until the lower surface of the purification panel falls on the pre-placed pad. At this time, the staff controls the remote control switch 7 to turn off, the telescopic end of the linear motor 9 rises and resets, and the lifting rod 10, the driving body 12 and the pressing plate 11 all perform the rising and resetting action. When the driving body 12 is out of contact with the lever 13, the rotating shaft 16 performs the reverse rotation action under the drive of the elastic member, and the other end of the baffle 17 rotates out of the purification panel hoisting area and returns to the initial position. The upper end of the rotating shaft 16 reels up the other end of the connecting rope 14, and one end of the connecting rope 14 pulls the other end of the lever 13 upward until the lever 13 is blocked by the limit block 15, and the entire device is restored to the state as shown. Figure 1 Status shown.
