[0002] With the rapid development and improvement of my country's construction industry, high-rise buildings and super high-rise buildings are now common. Considering the project cost calculation during the construction process, after the construction of the elevator machine room layer is completed, the indoor elevator can be considered. In this case, no decoration construction was carried out on the construction site, resulting in a height difference between the elevator door railing position and the structural surface. In the process of continued construction, materials need to be transported up and down by elevators, which will cause the elevator door railing to be crushed and damaged in the process. In this way, how to ensure the progress of the project, protect the finished products of the completed project, and avoid repeated turnover construction of the elevator door railing has become a problem that needs to be solved now.
[0003] In order to effectively speed up the progress of the project and protect the finished products of the completed project, our company uses a reusable elevator door railing protection connecting plate, which can effectively solve the problem and can be repeatedly constructed.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.
[0025] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0026] In the description of the present utility model, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed" etc. are understood to exclude the number itself, and "above", "below", "within" etc. are understood to include the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.
[0027] See also Figure 1-2 The utility model is an elevator door railing protection structure, including a chassis 1 and a support plate 3. The support plate 3 is located above the chassis 1. The total width of the support plate 3 matches the total width of the chassis 1. When transporting goods during construction, the device can be placed above the door railing position of the elevator door opening, thereby protecting the door railing. That is, the present application is applicable to the protection of elevator door railings in elevator door openings during the construction process of all projects under construction, especially in the construction of high-rise buildings with tight construction period requirements. And because the present application can be easily turned around, it can be placed in a designated position (at the elevator door opening) for use, and it is easy to use and reusable.
[0028] See also Figure 1-2In one embodiment of the utility model, the length dimension of the chassis 1 matches the dimension of the elevator door railing, such as 1100mm, which is adjusted according to the actual dimension of the elevator door opening (door railing). The chassis 1 may include two parallel main keels, which are fixedly connected by a plurality of secondary keels, and parallel transverse secondary keels may be arranged between the two main keels to enhance the overall strength of the device. Among them, the main keel may be a 40*40*2mm square steel tube, and the secondary keel may be a 20*20*2mm square steel tube. The fixed connection between the main keel and the secondary keel may be welding, and the welding quality shall meet the following requirements: the bracket welding meets the requirements of the third-level weld, the welding rod must use a welding rod that meets the strength, the weld penetration is not less than 70%, and the weld foot height is 10mm.
[0029] See also Figure 1-2 In one embodiment of the utility model, the support plate 3 can be a 3mm thick steel plate, and the support plate 3 can be fixedly laid on the chassis 1. The steel plate can ensure the force of the goods being rolled on the upper part. However, it is preferred that the support plate 3 is rotatably connected to the chassis 1, and the rotatable connection between the two can be a shaft connection or a hinge connection, such as connecting the two through a butterfly hinge 2, so that the support plate 3 can be turned over. A return spring 5 is provided at the connection position between the support plate 3 and the steel plate, and the return spring 5 is used to provide elastic force so that the support plate 3 and the chassis 1 are in a vertical state. The return spring 5 can be provided with a torsion spring or a compression spring. When the support plate 3 and the chassis 1 are connected through a shaft, a torsion spring or a compression spring can be selected. When the support plate 3 and the chassis 1 are connected through a hinge, a compression spring can be selected. By setting the return spring 5, the support plate 3 can be perpendicular to the chassis 1 in a normal state, thereby playing the role of a barrier. When in use, the support plate 3 can be laid flat and attached to the chassis 1 by an external force.
[0030] See also Figure 1-2In one embodiment of the utility model, the support plate 3 may include an integral steel plate, the total width of which corresponds to the total width of the chassis 1, and is connected to one side of the chassis 1; the support plate 3 may also be two split steel plates, the two split steel plates are respectively arranged on both sides of the chassis 1, and the total width of the two split steel plates after being assembled may correspond to the total width of the chassis 1, so as to be able to cover the chassis 1. When the number of steel plates is two, two cross-arranged tensile elastic members 4 may be arranged between the two split steel plates, that is, one end of the tensile elastic member 4 is connected to the upper end of one split steel plate, that is, the end away from the chassis 1, and the other end of the tensile elastic member 4 is connected to the middle position of the other split steel plate (in the up and down direction). And the sum of the widths of the two split steel plates is slightly larger than the width of the chassis 1. In this way, under normal conditions, the chassis 1 is placed at the elevator door opening, and the split steel plates are kept in a vertical state under the action of the return spring 5 to play a shielding role. When materials need to be transported, force is applied to make one of the split steel plates tend to be horizontal (i.e., rotate around the rotating connection position). In this process, the other split steel plate is pulled by pressing the crossed tensile elastic members 4, and a certain degree of rotation (tending to the horizontal) occurs, so that the two split steel plates can be attached to the chassis 1 for the transportation of materials. If the other split steel plate is not completely attached, it can also be pressed down by external force to make it completely attached so that the materials can pass through. There will be a certain overlap when the two split steel plates are superimposed, so that the width of the two steel plates can be consistent with the width of the chassis 1. After passing through, the split steel plates return to a vertical state to play a shielding role. The tensile elastic member 4 can be a tensile spring or an elastic rope, etc.
[0031] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model.
