The present disclosure belongs to the technical field of warehousing, and particularly relates to a material box warehousing system and a climbing robot. The present disclosure provides a material box warehousing system, which comprises a shelf and a climbing robot. The shelf is provided with at least one guide rail extending in a direction perpendicular to a working surface. The climbing robot comprises a main body, only one climbing assembly and a taking and placing box mechanism. The main body travels along the working surface under the action of a walking driving mechanism. The climbing assembly is arranged on the main body and is configured to be connected with one guide rail on the shelf. After being connected, the main body is driven by a climbing driving mechanism to ascend and descend along the guide rail. The taking and placing box mechanism is movably arranged on the main body and is configured to take out a target object from a target storage position or place the target object into the target storage position under the action of a taking driving mechanism. The guide rails are arranged on both sides of each column of material boxes, so as to reduce the occupation of the guide rails on the warehousing space.

The invention provides an elevator structure capable of conveniently transporting super-long objects. The elevator structure comprises a shaft, a car frame arranged in the shaft in a lifting mode and a car arranged on the car frame in a turnover mode. A car door is arranged on one side of the lift car, a movable opening is formed in the bottom of the lift car and provided with a movable door plate capable of being opened and closed, the bottom of the lift car is further connected with a detachable supporting structure, and the supporting structure is located at the bottom of the movable door plate so as to support the movable door plate. The car frame is provided with a turnover mechanism used for driving the car to turn over. Reserved openings are formed in the positions, corresponding to at least two floors, of the shaft on the rear side shaft wall, and the reserved openings are used for providing overturning space for the lift car. The ultra-long objects can be directly fed into the lift car from the movable opening in the bottom of the lift car in the state tending to be horizontal, and interference with the landing door structure is avoided. The reserved opening is formed in the hoistway, the overturning space is provided for the lift car, the reserved opening can be only formed in part of floors, and the occupied building area is small.

This invention relates to the field of smart grid technology and discloses a switchgear discharge fault detection device. The device includes a cabinet with an arc-shaped cover fixedly installed on the outer wall of the bottom end. A detection component is mounted on the cabinet door. This switchgear discharge fault detection device, by setting up the detection component and cooperating with horizontal and vertical linear modules, enables the main asynchronous motor to move along two axes. When the main asynchronous motor is started, the rotating shaft drives the cross plate to rotate vertically. Multiple sets of hydraulic rods extend to extend corresponding detection mechanisms to perform multiple detection methods, improving accuracy and preventing the discharge phenomenon from going undetected due to the failure of a single detection method, thus avoiding more serious consequences and losses. This allows for better discharge fault detection and precise location of the discharge point. Furthermore, the detection component is integrated into the cabinet door, reducing the encroachment on the internal space of the cabinet and facilitating disassembly and maintenance.
