Description

Technical Field

[0001] The utility model belongs to the technical field of bucket elevators, in particular to a bucket elevator inspection door mechanism which is fully automatically opened and closed and has a glass door. Background Art

[0002] Daily maintenance of the elevator requires frequent opening of the inspection door for observation and maintenance. Each time the inspection door is opened or closed, many nuts need to be removed for fitting. In addition, the inspection door is extremely heavy, which is very time-consuming and labor-intensive, and the workload is heavy. In addition, the traditional inspection door cannot observe the internal structure of the bucket elevator without removing the inspection door, resulting in the inability to discover hidden dangers and thus prevent them from happening. There are generally three locations for the inspection door: 1. The bottom area near the feed port and the drive device is used to check the transmission components at the bottom and the initial loading of the hopper; 2. The middle area is used to check the operating status of the hopper during the lifting process and the tension of the chain or belt; 3. The top area near the discharge port is used to check the discharge status of the discharge port and the wear of the top transmission components.

[0003] Chinese patent publication number CN212402407U discloses a glass inspection door for a bucket elevator, comprising 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, wherein the inner layer of tempered float glass is bonded to the outer layer of tempered float glass via the adhesive layer. Using laminated glass as protection for the hollow window of the inspection door facilitates operator observation and inspection while the equipment is operating, allowing operators to promptly identify potential hazards and avoid accidents. Laminated glass is strong and wear-resistant, preventing wear and damage from materials. There is no need for additional wear-resistant plates made of PE material, reducing costs. The material of the laminated glass is consistent with that of the elevator material, preventing the introduction of iron impurities and thus preventing material contamination.

[0004] In actual applications, the inside of the glass is often contaminated with dust and other substances that affect the observation of the equipment, so the inspection door often needs to be opened to observe the equipment or clean the dust. For the inspection doors in the middle and top areas, it is often necessary to use a ladder or climb to the operating platform to reach the inspection position. The observation position for manual inspection is on the door opening path when the inspection door opens outward, and the operator needs to avoid it during the door opening process. The position of the ladder or operating platform is relatively narrow, and the process of avoiding the door will pose certain safety hazards. In addition, the inspection door has a relatively large weight and windward area. Affected by its own gravity and external wind force, the door opening and closing process is not convenient for manual operation. Utility Model Content

[0020] 1. The door panel slides longitudinally to open or close the inspection port. The movement path of the door panel does not interfere with the operator's observation position, which improves the safety of operation. At the same time, the opening and closing process does not increase the windward area of the door panel, making it easier to open and close the door panel.

[0021] 2. The movement of the movable frame drives the sliding of the door panel. The sliding of the door panel into the inspection port can increase the sealing effect of the inspection port; the sliding of the door panel away from the inspection port provides an operating space for cleaning the attachments on the inside of the tempered glass, which helps to improve the clarity of observation.

[0022] 3. The use of motor as the power source reduces manual workload; the motor has a self-locking function, providing locking force for the door panel, and combined with the elastic strip and the inner extension frame, it greatly improves the sealing effect of the door panel; the tempered glass can quickly observe the equipment status, improving the detection efficiency.
