[0019] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0020] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0021] As Figures 1-3 shown, in the embodiment of the present utility model: A special hydraulic lifting platform for traffic facility maintenance includes a mobile trolley 1 and a hydraulic lifting frame 2.

[0022] In specific operations, the hydraulic lifting frame 2 is installed inside the mobile trolley 1. The top of the hydraulic lifting frame 2 is fixedly installed with a lifting tabletop 3. The right side of the lifting tabletop 3 is provided with a motor box 301, and a horizontal movement motor 302 is installed inside the motor box 301. The horizontal movement screw 303 is installed inside the lifting tabletop 3, and a moving slider 4 is installed on the surface of the horizontal movement screw 303;

[0023] The bearing steel bars 401 are inserted into the moving slider 4. The bottom end of the moving slider 4 is fixedly installed with a limiting slider 402. The top end of the moving slider 4 is fixedly installed with a connecting slider 403. The top end of the connecting slider 403 is fixedly installed with a safety protection frame 5, and a support block 6 is installed on the right side of the safety protection frame 5.

[0024] Through the above technical solution, after the lifting tabletop 3 rises to a high place, the rotation of the horizontal movement motor 302 can make the horizontal movement screw 303 rotate. As the horizontal movement screw 303 rotates, the moving slider 4 drives the safety protection frame 5 to move horizontally, so as to meet the horizontal movement requirements of the staff standing inside the safety protection frame 5.

[0025] The bottom end of the mobile trolley 1 is equipped with moving wheels 101, a pushing frame 102 is fixedly installed on the right side of the mobile trolley 1, and a climbing block 103 is fixedly installed on the left side of the mobile trolley 1.

[0026] There are two groups of climbing blocks 103 arranged on the left side of the mobile trolley 1, and the lengths of the two groups of climbing blocks 103 gradually decrease with their height. A set of rectangular grooves are opened at the top end of the mobile trolley 1, and the bottom end of the hydraulic lifting frame 2 is fixedly installed on the bottom surface of the rectangular groove opened at the top end of the mobile trolley 1.

[0027] Through the above technical solution, since two groups of climbing blocks 103 with gradually decreasing lengths are installed on the left side of the mobile trolley 1, it is convenient for the staff to step on the top of the climbing blocks 103 and climb into the inside of the safety protection frame 5. By using the hydraulic lifting frame 2 to connect the mobile trolley 1 and the lifting table surface 3, the lifting table surface 3 can be raised as the hydraulic lifting frame 2 rises.

[0028] The output shaft of the horizontal movement motor 302 is fixedly connected to the right side of the horizontal movement screw 303. The horizontal movement screw 303 is installed on the inner walls of both sides of the lifting table surface 3 through bearing seats. Two circular through holes adapted to the diameter of the bearing steel bars 401 are opened inside the moving slider 4. There are two groups of bearing steel bars 401, and both ends of the two groups of bearing steel bars 401 are fixedly installed on the inner walls of both sides of the lifting table surface 3. A circular threaded hole adapted to the size of the horizontal movement screw 303 is opened inside the moving slider 4.

[0029] Through the above technical solution, the rotation of the horizontal movement motor 302 can cause the horizontal movement screw 303 to rotate. And through the rotation of the horizontal movement screw 303, the part of the inner part of the moving slider 4 that meshes with the surface of the horizontal movement screw 303 moves horizontally on the surface of the horizontal movement screw 303. By passing the bearing steel bars 401 through the inside of the moving slider 4, the moving slider 4 can be protected from pressure, and it can prevent damage to the moving slider 4 and the limit slider 402 due to excessive pressure generated by the staff standing inside the safety protection frame 5.

[0030] Control buttons 501 are arranged on the inner wall of the safety protection frame 5. The top end of the support block 6 is fixedly installed with a lifting frame 601. An electric lifting motor 602 is installed inside the lifting frame 601. A lifting screw 603 is installed inside the lifting frame 601, and an internally threaded slider 604 is installed on the surface of the lifting screw 603. A tool box 605 is fixedly installed on the side of the internally threaded slider 604.

[0031] Inside the lifting frame 601, a partition with a circular hole is installed. The bottom end of the lifting screw 603 is inserted into the partition installed inside the lifting frame 601. A set of circular screw holes that mesh with the surface of the lifting screw 603 are opened inside the internally threaded slider 604. A set of rectangular blocks are arranged on the left side of the internally threaded slider 604, and the rectangular blocks arranged on the left side of the internally threaded slider 604 are adapted to the dimensions of the rectangular hole slots opened on the left side of the lifting frame 601.

[0032] Through the above technical solution, when the staff stands inside the safety protection frame 5 to repair traffic facilities, they can press the control button 501 to send themselves to a suitable position. The rotation of the lifting motor 602 will cause the tool frame 605 to be lifted and adjusted on the side of the lifting frame 601. After the tool frame 605 is adjusted to a suitable height, it is convenient for the staff to take repair tools inside it.

[0033] In summary, the working principle of the present utility model is as follows: When it is necessary to enable the staff to perform horizontal position movement adjustment at a high place, when the staff climbs into the safety protection frame 5 through the climbing block 103 and uses the hydraulic lifting frame 2 to rise to a high place to repair traffic facilities, the staff can press the control button 501 to make the horizontal movement motor 302 rotate. The rotation of the horizontal movement motor 302 can cause the horizontal movement screw 303 to rotate. When the horizontal movement screw 303 rotates, the moving slider 4 will slide horizontally on its surface. Since the top end of the connecting slider 403 is fixedly connected to the bottom end of the safety protection frame 5, when the moving slider 4 and the connecting slider 403 move, the safety protection frame 5 will also move horizontally. In this way, the safety protection frame 5 can be moved at the top of the lifting table 3, so as to meet the need for the staff to adjust their positions when repairing traffic facilities at a high place. The rotation of the lifting motor 602 can cause the lifting screw 603 to rotate. When the lifting screw 603 rotates, the internally threaded slider 604 can slide up and down on its surface. By using the up and down sliding of the internally threaded slider 604, the tool frame 605 can be moved up and down. After the tool frame 605 is moved to a suitable height, it is convenient for the staff to take repair tools inside the tool frame 605 for use.

[0034] The above is only a preferred embodiment of the present utility model, and it does not limit the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still belong to the protection scope of the technical solution of the present utility model.
