Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 In this embodiment of the utility model, an aluminum alloy mast-type lifting platform includes a lifting platform body 1. A support plate 2 is fixedly connected to the top of the lifting platform body 1, and a guardrail 3 is fixedly connected to the top of the support plate 2. A protective mechanism 4 is provided on the outer side of the guardrail 3. Four self-locking casters 5 are rotatably connected to the bottom of the lifting platform body 1. The four self-locking casters 5 are located at the four corners of the bottom of the lifting platform body 1, facilitating the operator's movement of the lifting platform. Support plates 6 are welded to both sides of the lifting platform body 1. A threaded sleeve 7 is fixedly connected to the top of the support plate 6. A threaded rod 8 is threadedly connected to the inner side of the threaded sleeve 7, and the threaded rod 8 completely penetrates the threaded sleeve 7. A clamping plate 9 is fixedly connected to the bottom of the threaded rod 8. After the lifting platform is moved, the threaded rod can be rotated to move the clamping plate 9 downwards, making it contact the ground, increasing the friction between the lifting platform and the ground, and preventing the lifting platform from slipping during operation. The inner side of the guardrail 3 has a receiving groove and a closing groove, which are integrally formed. An electric push rod 10 is fixedly installed inside the receiving groove. The output end of the electric push rod 10 is fixedly connected to a closing door 11, which is slidably connected inside the closing groove. When the electric push rod 10 is activated, it can drive the closing door 11 to close inside the closing groove, realizing the opening and closing of the guardrail 3 and facilitating the entry and exit of construction personnel.

[0020] like Figure 1 , Figure 2 and Figure 3As shown, the protective mechanism 4 includes a first upright 12 fixedly connected to one side of the guardrail 3, and a second upright 13 fixedly connected to the other side of the guardrail 3. A servo motor 14 is fixedly connected to the bottom of the first upright 12. A first mounting groove 16 is provided inside the first upright 12. A lead screw 15 is fixedly installed at the output end of the servo motor 14 through a coupling. The lead screw 15 is installed inside the first mounting groove 16 through a bearing. A second mounting groove 18 is provided inside the second upright 13. A guide rod 17 is fixedly connected inside the second mounting groove 18. The outer wall of the lead screw 15 is threaded with a lifting block 19, the outer wall of the guide rod 17 is slidably connected with a guide block 21, a first connecting block 20 is fixedly connected to one side of the lifting block 19, a second connecting block 22 is fixedly connected to one side of the guide block 21, a first fixing rod 23 is fixedly connected to the top of the first connecting block 20, a second fixing rod 24 is fixedly connected to the top of the second connecting block 22, the tops of the first fixing rod 23 and the second fixing rod 24 are both welded to the bottom of the protective plate 25, and a triangular plate 26 is fixedly connected to the top of the protective plate 25.

[0021] The working principle of this utility model is as follows:

[0022] When in use, the servo motor 14 can be started. After the servo motor 14 is started, it drives the lead screw 15 to rotate. After the lead screw 15 rotates, it works with the guide rod 17 and the guide block 21 to drive the lifting block 19 to move up and down. The lifting block 19 moves up and down, and with the connection between the first connecting block 20 and the second connecting block 22, it drives the first fixed rod 23 and the second fixed rod 24 to move up, so that the protective plate 25 is raised to provide protection and block falling objects from the outside. After the protective plate 25 is raised and lowered, it can be stored. It can be stored with the guardrail 3 to reduce the space occupied by the elevator when it is not in use and make it more convenient for operators to store the elevator.
