[0001] The utility model relates to the field of construction elevators, in particular to a door stopper for construction elevators. Background Art

[0002] Construction elevators are one of the indispensable mechanical equipment in construction. The vigorous development of my country's construction industry has put forward higher requirements on the performance of construction elevators. The development of various new types of construction elevators has become one of the hot spots in the current construction machinery industry. In the existing construction process, construction electric vehicles are usually required to transport construction materials at high levels. The construction electric vehicles go back and forth in the elevator cage, which may impact the feed door, causing damage or falling of the feed door, which can easily cause safety accidents. The existing construction elevator door stop solution is to add a fence-like structure to the feed door structure. The structure of the door stop is relatively complex, and it is difficult to make and install, and it is inconvenient to use; and the height of the door stop should not be too high, otherwise it will affect normal entry and exit. Because the door stop is fixed, its height cannot be adjusted, and it cannot be applied to various types of construction electric vehicles. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the existing door stops are difficult to manufacture and install, and at the same time, the door stops can only be installed at a lower height without affecting normal passage, and cannot be applied to construction electric vehicles of different types and heights; in view of the above problem, a door stop for a construction elevator is proposed, comprising two lifting rings, a steel wire rope and a carabiner, the two lifting rings are respectively arranged on the two side walls inside the elevator cage and are located at the same height position, the fixing points of the two lifting rings are at the same distance from the plane where the feed door is located, one end of the steel wire rope is connected to the lifting ring on one side of the elevator cage, the other end of the steel wire rope is connected to the carabiner, and the carabiner is buckled with the lifting ring on the other side of the elevator cage.

[0004] The technical solution of the utility model is to set a steel wire rope as the door stop structure, which is fixed by a mountaineering buckle and a lifting ring. It is simple to manufacture and easy to use, and the installation height can be set according to the actual height of the construction electric vehicle. Since the mountaineering buckle can be opened at any time, it will not hinder the construction electric vehicle from entering the elevator cage normally.

[0005] Preferably, the tail end of the lifting ring has a thread, and the lifting ring is fixed to the side wall of the elevator cage by an M10 nut. The thread of the lifting ring matches the M10 nut, and the installation and fixing are convenient, and the M10 nut has sufficient strength.

[0006] In the preferred embodiment of the technical solution of the utility model, the installation height of the lifting ring is adjusted according to the actual height of the electric construction vehicle, and can be applied to electric construction vehicles of different types and heights without affecting normal traffic.

[0007] Preferably, the distance between the lifting ring and the feed door is H. After the lifting ring fixes the wire rope, there is a certain distance between the lifting ring and the feed door, so the electric vehicle will not collide or impact the feed door to cause a safety accident.

[0008] Preferably, the steel wire rope is relaxed, and the maximum distance the steel wire rope moves toward the feed door after being stressed is less than H. The relaxed steel wire rope facilitates the flexible opening or buckling of the carabiner, and the maximum displacement distance of the steel wire rope is less than H, thereby protecting the feed door from the impact of the electric construction vehicle.

[0012] Figure 1 This is a schematic elevation diagram of a door stop installation for a construction elevator;

[0013] Figure 2 It is a partially enlarged schematic diagram of a door stopper for a construction elevator;

[0014] Among them: 1-lifting ring, 2-wire rope, 3-carabiner, 4-lift cage. DETAILED DESCRIPTION

[0015] The following will be combined with the attached embodiment of the utility model Figure 1-2 , the technical solutions in the embodiments of the utility model are described in detail. Example 1

[0016] like Figure 1-2 As shown, the utility model is a door stopper for a construction elevator, comprising two lifting rings 1, a steel wire rope 2 and a carabiner 3, and all the structures are installed inside a hoist cage 4 of the elevator.

[0017] The elevator cage 4 opens as a feed door when it is on the first floor, and opens as a discharge door when it is on the second floor and above. The feed door and the discharge door are usually arranged relative to each other.

[0018] The φ of the lifting ring 1 is 10mm. The two lifting rings 1 are respectively installed on the two side walls of the elevator cage 4 where the door is not opened. The tail end of the lifting ring 1 passes through the side wall of the elevator cage 4, and its tail end has a thread. By threaded connection with the M10 nut, the lifting ring 1 is fixed and locked as a whole and installed on the side wall of the elevator cage 4.

[0019] The two lifting rings 1 have the same height and can be installed at a suitable height according to the actual height of the electric construction vehicle to block the electric vehicle and prevent it from hitting the feed door and causing a safety accident. For construction electric vehicles of normal specifications, the installation height of the lifting ring 1 is generally set to 600mm.

[0020] Preferably, the elevator cage 4 may be provided with a plurality of through holes in the vertical direction at the installation position of the lifting ring 1, so as to facilitate the selection of a suitable height for the installation of the lifting ring 1.

[0021] The preferred specification of the wire rope 2 is 6×37-11. One end of the wire rope 2 is connected to the ring 1 on one side of the elevator cage 4, and the other end of the wire rope 2 is connected to the carabiner 3. The specific connection method of the wire rope 2 with the ring 1 and the carabiner 3 adopts the aluminum alloy pressing head method, which is a conventional method in this field.

[0022] The preferred model of the carabiner 3 is M10×100, and the carabiner 3 is buckled with the lifting ring 1 on the other side of the elevator cage 4.

[0023] The installation and fixing points of the two lifting rings 1 are at the same distance from the plane where the feed door is located, which is set to H. Under normal circumstances, H is 300mm. The wire rope 2 is loose, which is convenient for the disassembly and connection of the carabiner 3. The maximum distance of the displacement of the wire rope 2 toward the feed door after being stressed is less than H. Therefore, even if the construction electric vehicle accidentally collides with the feed door, it will be blocked by the wire rope 2 and no collision will occur.

[0024] The overall method of use is: when on the first floor, unfasten the carabiner 3 from the lifting ring 1 to facilitate the electric vehicle used for construction to enter the elevator cage 4, and then buckle the carabiner 3 with the lifting ring 1. After the elevator cage 4 rises, the opposite discharge door opens, and the electric vehicle goes out from the discharge door to transport the construction materials to the corresponding floor.

[0025] After the transportation is completed, the electric vehicle enters the elevator cage 4. At this time, the wire rope 2 can block the electric vehicle to prevent the electric vehicle from directly hitting the feed door, causing the feed door to be deformed or damaged, causing a greater safety accident.

[0026] A method for using a door stopper for a construction elevator in this embodiment is as follows:

[0027] After the door stop is installed, when it is necessary to enter the elevator cage 4 from the feed door normally on the first floor, the carabiner 3 can be untied from the lifting ring 1. After the construction electric vehicle and all operators enter, the carabiner 3 can be buckled onto the lifting ring 1, and the construction electric vehicle enters the corresponding floor from the opposite discharge door to transport construction materials. After the transportation is completed, the construction electric vehicle returns to the elevator cage 4 from the discharge door. Since the wire rope 2 is stretched between the two lifting rings 1 at this time, it can prevent the construction electric vehicle from hitting the feed door of the elevator cage 4, thereby reducing the probability of installation accidents and improving construction safety.

[0028] The above embodiments are only for illustrating the technical idea of ​​the present utility model, and cannot be used to limit the protection scope of the present utility model. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present utility model shall fall within the protection scope of the present utility model.
