[0046] The working principle of this utility model:

[0047] During the installation of the device, the limit rod 2 can be placed outside the elevator entrance 11, the L-shaped plate 6 can be placed inside the elevator entrance 11, and the threaded rod 63 can be inserted into the corresponding hole on the limit rod 2, and then the nut 64 can be threadedly connected to the threaded rod 63, and one side of the nut 64 can be tightly pressed against the surface of the limit rod 2. In this way, the limit rod 2 and the limit support frame can be fixedly connected in the elevator entrance 11 to ensure the stability of the subsequent installation support structure, and then the rotation groove 31 of the support frame 3 is plugged into the support shaft 62, and the support frame 3 is rotated in the direction of the elevator shaft 1. It should be noted that the support frame 3 The length of is greater than the distance from the support shaft 62 to the inner wall of the elevator shaft 1, so that the end of the support frame 3 away from the rotating groove 31 will abut against the inner wall of the elevator shaft 1, thereby making the support frame 3 tilted at a small angle and supported in the elevator shaft 1, so that the support frame 3 is symmetrically installed on the two support shafts 62 in turn, and then the support plate 4 is laid on the two support frames 3, wherein the bottom of the support plate 4 is fixedly connected to the limiting plate 43, which can facilitate the position of the support plate 4 to the left and right, ensuring that the support plate 4 will not be offset after being laid on the support frame 3, and the limiting convex strip 4 fixedly connected to one side of the support plate 4 1 and the limiting groove 42 opened on the other side thereof cooperate with each other. In this way, during the laying process of the support plates 4, the limiting convex strip 41 on the previous support plate 4 and the limiting groove 42 on the next support plate 4 can be correspondingly plugged in, thereby ensuring the purpose of directly and stably connecting each support plate 4. In this way, the support plates 4 are plugged in one by one and the support plates 4 after the plugging are moved away from the limiting rod 2. When the last support plate 4 is plugged in, the limiting convex strip 41 on the support plate 4 can be snapped into the limiting stop groove 21 on the limiting rod 2, so that all the support plates 4 are completed. The purpose of the front and rear limiting is to ensure that the support plate 4 laid on the support frame 3 will not slide forward, backward, left or right during use. Then the rotating plates 5 rotatably connected to the two ends of each support plate 4 can be rotated and opened, so that the rotating plates 5 can block and support the unblocked parts of the elevator shaft 1 at both ends of the support plates 4, thereby completing the protective installation of the elevator shaft 1 at the floor limit rod 2. A baffle 51 is fixedly connected to the bottom of the rotating plate 5. After the rotating plate 5 is unfolded, one side of the baffle 51 will be supported against the side wall of the support frame 3, thereby ensuring the safety and stability of the installer when standing on the rotating plate 5.

[0048] After the installation of the equipment is completed, in the process of not installing the elevator in the elevator shaft 1, the guardrail installed outside the elevator entrance 11 can be used to effectively protect the elevator shaft 1 to prevent pedestrians from accidentally entering the elevator shaft 1 when passing by and causing safety accidents. In the process of installing the elevator in the elevator shaft 1, it can effectively intercept and protect against falling objects from high altitudes above the elevator shaft 1, thereby ensuring the safety of the construction personnel. In addition, when installing elevator guide rails, traction wire ropes and other equipment in the elevator shaft 1, the rotating plates 5 on both sides of the support plate 4 can be rotated and folded on the support plate 4, which is convenient for the installation of elevator guide rails, traction wire ropes and other equipment, thereby improving the safety during the installation of the elevator.
