[0001] The utility model belongs to the technical direction of construction elevators for building engineering, and specifically relates to a zero-power consumption construction elevator floor protection door gravity self-locking device. Background Art

[0002] In the application process of construction elevators, the floor protection doors are usually bolt-type or latch-type, and the elevator driver needs to lock them from the inside. However, if the driver is careless and forgets to lock them, the protection doors are wide open, and the edge protection is missing, it may cause accidents such as workers falling from high altitudes. At present, there are some electric self-locking devices or self-locking devices with complex processes, but they will increase the construction cost, so the actual application effect is not great. For this reason, there is an urgent need for an automatic locking device with low cost, simple process, and can be made by the project itself. This device came into being under this condition.

[0015] The following is a further non-limiting detailed description of the technical solution of the utility model in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-3 The utility model provides a technical solution: a gravity self-locking device for floor protection doors of a zero-power construction elevator, comprising a right door 1, a left door 2, an iron bolt 3 and a steel bar limiter 4, one end of the iron bolt 3 is fixed to the iron plate of the right door 1, and the other end of the iron bolt 3 protrudes out of the door frame, and the steel bar limiter 4 is fixed to the iron plate of the left door 2. By arranging the right door 1, the left door 2, the iron bolt 3, the steel bar limiter 4, the Z-shaped steel bar 5, the vertical plywood 6, the smooth round steel bar 7 and the horizontal pad 8, it is convenient for on-site workers to make it after using local materials, thereby achieving cost saving, and the manufacturing is simple, and the convenience of operation is improved. At the same time, when in use, it can be automatically locked as the protection door is closed, without the need for additional power assistance, effectively reducing energy consumption, further reducing costs, and at the same time, it is simple to install and disassemble, and it is firm, stable and durable after installation, which is convenient for repeated use.

[0017] Furthermore, the steel bar stopper 4 is composed of two vertical clamping plates 6 with holes at the front end, a Z-shaped steel bar 5 and a horizontal pad 8 with a slightly downwardly bent front end.

[0018] Furthermore, a plain round steel bar 7 is welded to the middle and lower part of the waist of the Z-shaped steel bar 5. The upper weight of the plain round steel bar 7 is greater than the lower weight, which is conducive to the upper part of the Z-shaped steel bar 5 leaning back and the lower part tilting up in a natural state.

[0019] Furthermore, the plain round steel bar 7 cooperates with the through holes of the vertical clamping plates 6, which facilitates the plain round steel bar 7 to be clamped in the through holes of the two vertical clamping plates 6 and to be flexibly rotated.

[0020] When in use, in a natural state, the upper part of the Z-shaped steel bar 5 leans back to touch the iron plate of the left door 2, and its lower part is in an upward state, and the end touches the horizontal pad 8. When the right door 1 is closed, the lower end of the Z-shaped steel bar 5 is rotated and lifted under the thrust of the iron bolt 3. After the iron bolt 3 passes, the lower end of the Z-shaped steel bar 5 returns to its original position under the influence of gravity. When the door is pushed open from the outside of the protective door with external force, the iron bolt 3 slides outward to touch the lower end of the Z-shaped steel bar 5 to rotate it, and the upper top touches the iron plate of the left door 2 to close. The iron bolt 3 is fixed so that it cannot slide out of the steel bar limiter 4, which plays an automatic locking and protection role, thereby achieving the goal of no need for power drive and reducing energy consumption. In this process, if you want to open the protective door, you can only push the right protective door forward from the inside, leaving an appropriate distance between the iron bolt 3 and the lower end of the Z-shaped steel bar 5, and then pull the upper top of the steel bar limiter 4 outward, and the lower end of the steel bar limiter 4 is rotated and lifted, and the iron bolt 3 is pulled out from the bottom, and the protective door can be opened, which is simple to operate and is convenient for quick use by staff.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0022] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit them. Although the utility model is described in detail with reference to the above embodiments, a person skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features can be replaced by equivalents, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
