The bottom structure of the elevator can be accessed in the pit, and the bottom of the elevator car can be inspected. There are also safety facilities in the pit that also need to be repaired. Usually the pit is lower than the ground of the building, and a ladder is required to enter the pit. If the matching ladder is not set near the pit, it will be easily misappropriated and cannot be found when needed. If it is set near the pit, there will be no space for it. Therefore, the ladder structure needs to be improved so that it can be conveniently stored near the pit environment. Utility Model Content

The straight ladder is the main body of the ladder, and it is hung on the wall bracket against the wall in the storage state, and there is a reset switch on the wall bracket. When hanging, the reset switch is pressed down, the safety circuit of the elevator is in a closed state, and the elevator can operate normally. When the ladder is in the working state, it is taken down, and the bottom is inserted into the pit fixed bracket to form a support angle, which is convenient for going down to the pit.
[0005] Furthermore, the straight ladder is a segmented structure, and the segmented parts are connected by rigid connectors to form a rigid working length. The straight ladder is connected with a steel wire rope, one end of which is fixed to the wall by an expansion bolt, and the other end is connected to the rigid connector by a clamp ring. The straight ladder is a segmented structure, and during transportation, it is packaged in segments and assembled on site. The straight ladder is also connected with a steel wire rope to prevent the straight ladder from being diverted to other places.
[0006] Furthermore, the wall bracket includes a fixing plate fixed to the wall, a supporting plate supporting the ladder and a baffle preventing the ladder from moving, and a reinforcing rib is fixed between the fixing plate and the supporting plate. The wall bracket can be formed by bending a plate and can cooperate with the reinforcing rib to achieve the required structural strength.
[0007] Further, the reset switch is fixed on the side of the wall bracket, the top of which is the trigger part and is arranged above the surface of the support plate. The reset switch is directly installed on the side of the wall bracket, and the reinforcing rib of the wall bracket can be at its edge position and can be used to fix the reset switch.
[0008] Furthermore, the pit fixing bracket includes a ground fixing frame and a ladder fixing groove. The ground fixing frame is fixed on the ground of the pit, and the ladder fixing groove is fixed on the ground fixing frame. The ladder fixing groove has a notch structure facing upward, and the angle between the notch structure and the horizontal plane is 60° to 80°. The ground fixing frame is a basic structure fixed on the ground, and the ladder fixing groove cooperates with the bottom of the straight ladder and has an angle, which can achieve stable support and improve the safety of the ladder.
[0009] Compared with the prior art, the utility model has the following advantages and effects: the design is a ladder device for an elevator to enter a pit, which can be convenient for maintenance personnel to use, and has a reliable safety device to effectively protect the safety of the staff. The ladder can be used exclusively to avoid being nowhere to find it when needed. BRIEF DESCRIPTION OF THE DRAWINGS
