Description

Technical Field

[0001] The utility model relates to the technical field of elevator safety equipment, in particular to a stopping device for an elevator pit. Background Art

[0002] An elevator is a vertical transportation tool used to transport people or objects on a vertical axis inside or outside a building. An elevator usually consists of an electric motor and a set of steel cables or hydraulic systems to raise or lower the elevator's load compartment. The elevator is also equipped with a control system to select and control the elevator's destination. The main function of an elevator is to provide fast, safe and convenient vertical transportation. They can provide a convenient way to go up and down stairs in high-rise buildings, reducing the labor and time cost of people climbing stairs. Elevators also provide barrier-free transportation options, which are convenient for the elderly, the disabled and people carrying large items. Elevators are usually equipped with a variety of safety devices, such as speed limiters, safety clamps, overload protection devices and emergency stop buttons. Elevators also have strict maintenance and inspection requirements to ensure their normal operation and safety. With the advancement of technology, the design and function of elevators are also constantly evolving. Modern elevators are usually equipped with intelligent systems, such as touch screen control, voice prompts and remote monitoring. Some high-end elevators also have luxurious decorations and special functions, such as glass bottom cabins, panoramic sightseeing and music playback.

[0003] In the prior art, elevators need to be regularly maintained during operation. During the maintenance, maintenance personnel will enter the elevator shaft at the bottom of the elevator. During this process, they need to pay attention to the condition of the elevator to prevent it from falling suddenly. Based on this problem, we proposed a stop device for the elevator pit.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A stopping device for an elevator pit comprises two side panels, the two side panels are respectively fixedly connected to the two sides of the elevator shaft, two top panels are arranged between the two side panels, the two top panels are connected by a docking device, sliding devices are arranged through the side walls of the two top panels, and positioning devices are arranged through the side walls of the two side panels at corresponding positions.

[0007] Preferably, handles are fixedly connected to the front side walls of the two top plates.

[0008] Preferably, the docking device comprises two docking grooves respectively penetrating the side walls of the two top plates, the positions of the two docking grooves correspond to each other, and a connecting plate is slidably connected between the two docking grooves.

[0009] Preferably, the sliding device includes two guide holes penetrating the side wall of the top plate, and two fixing seats are fixedly connected to the inner wall of the side plate at corresponding positions. The upper ends of the two fixing seats are fixedly connected with guide columns, and the two guide columns are respectively slidably connected in the two guide holes.

[0010] Preferably, the positioning device includes an oblique slot penetrating through the side wall of the side plate, and a placement slot is penetrating through the upper end of the top plate at the corresponding position, a positioning steel plate is placed in the placement slot, and the size of the positioning steel plate corresponds to the size of the oblique slot.

[0011] Preferably, the cross-sections of the two side panels are both concave.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] In the utility model, by arranging a docking device, a sliding device and a positioning device to cooperate with each other, the side panels are usually arranged on both sides of the elevator shaft, and the top plate is at the bottom, which will not affect the normal function of the elevator shaft. When maintenance is needed, the positioning steel plates can be removed and the corresponding top plates can be pulled up by the handles, and the removed positioning steel plates can be inserted into the corresponding oblique slots. After the handles are released, the top plates can be supported by the positioning steel plates on both sides. The positioning steel plates form a stable triangular support between the contact surfaces of the top plates in the oblique slots, which can improve the stability of the support. The top plates are also docked by connecting plates, which can further improve the stability of the two top plates, thereby ensuring the personal safety of maintenance personnel during maintenance.
