Description

Technical Field

[0001] This utility model belongs to the field of hoisting technology, and in particular relates to a hoisting machine with an easy-open glass inspection door. Background Technology

[0002] Bucket elevators are devices used for vertically lifting bulk materials and are widely used in various industrial production lines. To ensure the efficient and safe operation of bucket elevators, inspection doors are a crucial component. The main function of the inspection doors is to facilitate inspection, maintenance, and cleaning of the elevator's interior. In practical applications, to increase equipment and personnel safety and prevent foreign objects and personnel from falling into the elevator's operating parts through the inspection opening, the inspection doors are often locked to prevent unauthorized personnel from opening them. The most common and primary function of the inspection doors is to inspect the equipment's operation, promptly identify problems, and take appropriate measures. In such cases, it is often unnecessary to open the inspection door; simply observing the internal operation of the equipment through it is sufficient.

[0003] Chinese patent document CN212402407U discloses a glass inspection door for a bucket elevator, including a door frame and laminated glass fixed within the door frame. The laminated glass comprises an inner layer of tempered float glass, an adhesive layer, and an outer layer of tempered float glass, with the inner layer bonded to the outer layer via the adhesive layer. Using the laminated glass as the protective cover for the perforated window of the inspection door allows operators to easily observe and inspect the equipment while it is running, enabling timely detection of potential hazards and preventing accidents. The laminated glass is strong and wear-resistant, preventing damage from material abrasion, and eliminates the need for additional PE wear-resistant plates, reducing costs. Furthermore, the material of the laminated glass matches the material used in the elevator, preventing the introduction of iron impurities and thus avoiding material contamination.

[0004] During operation, the feeding and discharging of materials at the top and bottom of the elevator, as well as the vibrations generated by the chain rotation, produce dust and impurities inside the elevator. These substances easily adhere to and accumulate on the inside of the glass, reducing its light transmittance and increasing the difficulty of inspection over time. Furthermore, the inspection door is not intended for continuous use but rather for periodic checks. Therefore, each time the inspection door is needed, it must be opened and the impurities on the inner glass cleaned before use. Since the inspection door is already open, further inspection through the glass becomes pointless. Utility Model Content

[0005] To overcome the technical problem of dust and impurities generated during the operation of the hoist adhering and accumulating on the glass of the inspection door, reducing the glass's light transmittance and increasing the difficulty of inspection, this invention aims to provide a hoist with an easy-open glass inspection door. The hoist includes a cleaning brush for cleaning the glass, a storage cavity for preventing the cleaning brush from being contaminated by dust and impurities, and a sealing door. Externally, a drive column and a crank handle are provided for driving the cleaning brush and the sealing door, respectively. This allows for cleaning of the inside of the glass without opening the inspection door, followed by inspection of the operation through the glass, improving both convenience and safety.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a lifting machine with an easy-open glass inspection door, comprising an inspection door disposed on the outer wall of the lifting machine; glass disposed on the inspection door; a storage cavity disposed inside the lifting machine; an opening disposed on the side of the storage cavity facing the glass; a sealing door, one end of which is rotatably connected to the side of the opening away from the glass; and a cleaning brush, one end of which is rotatably connected to the storage cavity, the cleaning brush selectively abutting against the glass; wherein, a drive column rotatably connected to the lifting machine and driven by the cleaning brush is used to drive the cleaning brush to reciprocate; a crank handle is slidably connected to the drive column along the axial direction; an embedded groove is provided on the lifting machine for storing the crank handle; the crank handle is driven by the sealing door.

[0047] Optionally, the receiving cavity 12 is provided with a spray device for spraying water onto the glass 22; optionally, the welding frame 11 is provided with a supplementary light.

[0048] Usage: Pull the crank handle 31 out of the recessed groove 14. The crank handle 31 slides outward along the drive column 44, that is, the extension rod 313 slides outward. The sliding of the extension rod 313 drives the lever plate 45 to slide outward, which in turn causes the pressure rod 451 to slide outward. The sliding of the pressure rod 451 drives the support plate 511 to rotate, which in turn causes the sealing door 51 to rotate downward, and the torsion spring stores force.

[0049] Next, pull the handle 33 out of the slot 311, keeping the crank handle 31 at its outermost extreme position. Hold the handle 33 and rotate the crank handle 31. The rotation of the crank handle 31 causes the non-cylindrical 312 to rotate, which in turn causes the non-circular hole 441 to rotate, which in turn causes the drive column 44 to rotate. The rotation of the drive column 44 causes the eccentric shaft 443 to rotate, which in turn causes the driven groove 431 to slide back and forth, which in turn causes the rack 43 to slide back and forth. The back and forth sliding of the rack 43 causes the gear 421 to rotate back and forth, which in turn causes the cleaning brush 41 to rotate back and forth. The cleaning brush 41 rotates downward 90 degrees from the storage cavity 12 and then returns to its original position. This process is repeated. During the rotation of the cleaning brush 41, it brushes along the glass 22, removing dust and impurities from the glass 22.

[0050] After cleaning the glass 22, turn the crank handle 31 until it is aligned with the recessed groove 14. At this time, the cleaning brush 41 returns to the storage cavity 12. Release the crank handle 31, and the spring force will cause the sealing door 51 to rotate toward the storage cavity 12, closing the opening 15. The rotation of the sealing door 51 causes the support rod 511 to rotate, which in turn pushes the pressure rod 451 inward. The pressure rod 451 slides inward, simultaneously causing the lever 45 to slide inward. The lever 45 slides and pushes the extension rod 313, which in turn causes the crank handle 31 to return to the recessed groove 14. Finally, press the handle 33 back into the through groove 311.

[0051] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
