DETAILED DESCRIPTION

In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

As shown in Figures 1 to 4, an embodiment of the utility model provides a construction engineering lighting device, including a tower crane lamp 1 and a tower crane railing 2. The rear side of the tower crane lamp 1 is movably connected to the front side of the tower crane railing 2. Two device shells 3 are fixedly connected to the rear side of the tower crane lamp 1. A movable shell 4 is fixedly connected to the rear side of the tower crane lamp 1. Two extrusion control blocks 5 are arranged on the rear side of the tower crane lamp 1. The top and bottom of the extrusion control blocks 5 both penetrate the device shell 3 and extend to the inner cavity of the device shell 3. A limiting device 6 is arranged inside the device shell 3.

Referring to Figure 4, the limiting device 6 includes a limiting block 601, and the limiting block 601 is fixedly connected to two external shells 602 on one side close to the movable shell 4. The external shell 602 is fixedly connected to a spring 603 on one side close to the movable shell 4. The spring 603 is fixedly connected to the inner cavity of the device shell 3 on one side close to the inner cavity of the device shell 3.

The above solution is adopted: by providing the limiting device 6 , when the tower crane lamp 1 needs to be installed on the tower crane railing 2 , the limiting device 6 has a limiting effect on the position of the tower crane lamp 1 .

4 , the inner cavity of the outer shell 602 is movably connected to the inner shell 7 , and the side of the inner shell 7 close to the inner cavity of the device shell 3 is fixedly connected to the inner cavity of the device shell 3 .

By adopting the above solution: by setting the inner shell 7, when the limit block 601 moves, it will drive the outer shell 602 to move along the surface of the inner shell 7. The cooperation between the inner shell 7 and the outer shell 602 has a limiting effect on the moving position of the limit block 601.

Referring to Figure 4, the bottom of the inner cavity of the device shell 3 is movably connected to two extrusion rotating frames 8 used in conjunction with the extrusion control block 5 through a rotating shaft, the inner cavity of the extrusion rotating frame 8 is movably connected to the surface of the extrusion control block 5, and the rear side of the limit block 601 is fixedly connected to an extrusion block 9 used in conjunction with the extrusion rotating frame 8, and the surface of the extrusion block 9 is movably connected to the inner cavity of the extrusion rotating frame 8.

The above scheme is adopted: by setting the extrusion rotating frame 8 and the extrusion block 9, the extrusion force of the extrusion control block 5 on the extrusion rotating frame 8 can drive the extrusion rotating frame 8 to rotate along the surface of the extrusion block 9 through the rotating shaft. When the extrusion rotating frame 8 rotates, the extrusion force generated on the extrusion block 9 can drive the extrusion block 9 to move. When the extrusion block 9 moves, it can drive the limit block 601 to move.

4 , a moving rod 10 used in conjunction with the moving shell 4 is fixedly connected to opposite sides of the two extrusion control blocks 5 , and the surface of the moving rod 10 contacts the inner cavity of the moving shell 4 .

The above solution is adopted: by setting the moving rod 10, pulling the extrusion control block 5 will drive the moving rod 10 to move along the inner cavity of the moving shell 4. The coordinated use of the moving rod 10 and the moving shell 4 has a limiting effect on the moving position of the extrusion control block 5.

2 , a limiting groove 11 for use with a limiting block 601 is provided on the surface of the tower crane handrail 2 , and the surface of the limiting block 601 contacts the inner cavity of the limiting groove 11 .

The above scheme is adopted: by setting the limit groove 11, when the plug-in rod 12 is completely moved to the inner cavity of the plug-in groove 13, the squeezing control block 5 is released, and the restoring force generated by the spring 603 restoring its shape will drive the limit block 601 to be stuck into the inner cavity of the limit groove 11. The coordinated use of the limit block 601 and the limit groove 11 has a limiting effect on the position of the tower crane lamp 1 and the plug-in rod 12.

2 and 3 , four plug-in rods 12 are fixedly connected to the rear side of the tower crane lamp 1 , and a plug-in slot 13 for use with the plug-in rod 12 is provided on the front side of the tower crane handrail 2 , and the surface of the plug-in rod 12 contacts the inner cavity of the plug-in slot 13 .

The above scheme is adopted: by setting the plug-in rod 12 and the plug-in slot 13, the tower crane lamp 1 is moved to the side close to the tower crane railing 2. The movement of the tower crane lamp 1 will drive the plug-in rod 12 to move into the inner cavity of the plug-in slot 13. The coordinated use of the plug-in rod 12 and the plug-in slot 13 has a limiting effect on the moving position of the tower crane lamp 1, so that the limit block 601 can be accurately moved to the position where it can be stuck in the limit slot 11.

The working principle of this utility model:

During use, when it is necessary to conveniently and stably install the tower crane lamp 1 used in the construction project on the tower crane railing 2, the operator first moves the plug-in rod 12 to the side close to the inner cavity of the plug-in slot 13. The movement of the plug-in rod 12 drives the tower crane lamp 1 to move. When the plug-in rod 12 contacts the inner cavity of the plug-in slot 13, the extrusion control block 5 is pulled toward the opposite side of the two extrusion control blocks 5. When the extrusion control block 5 moves, it will drive the moving rod 10 to move along the inner cavity of the moving shell 4. When the extrusion control block 5 moves, it will generate an extrusion force on the extrusion rotating frame 8. The extrusion rotating frame 8 subjected to the extrusion force will rotate along the surface of the extrusion block 9 through the rotating shaft. When the extrusion block 9 is subjected to the extrusion force of the extrusion rotating frame 8, it will drive the limit The positioning block 601 moves, and the movement of the limiting block 601 can drive the outer shell 602 to move along the surface of the inner shell 7. The force generated when the outer shell 602 moves causes the spring 603 to undergo elastic deformation. When the limiting block 601 is completely moved to the inner cavity of the device shell 3, the plug-in rod 12 continues to be moved backward. When the plug-in rod 12 is completely moved to the inner cavity of the plug-in slot 13, the two extrusion control blocks 5 are released. The restoring force generated by the spring 603 restoring its shape will drive the limiting block 601 to be stuck into the inner cavity of the limiting slot 11. The coordinated use of the limiting block 601 and the limiting slot 11 has a limiting effect on the position of the tower crane 1. At this time, the tower crane 1 used in the construction project is conveniently and stably installed on the tower crane railing 2.

To sum up: the construction engineering lighting equipment, by setting the limiting device 6, the limiting block 601, the outer shell 602, the spring 603 and the limiting groove 11, solves the problem that the existing tower crane lamp refers to the lighting equipment installed on the tower crane, which is used to provide lighting for the engineering site at night or in low light conditions. The tower crane lamp is usually installed on the crossbeam or railing of the tower crane. When installing the existing tower crane lamp, bolts are often used to install the mounting frame on the tower crane, and then the tower crane lamp is installed on the mounting frame by bolts, or the tower crane lamp is directly fixed to the tower crane with ropes. The bolts and ropes are prone to aging after long-term use, resulting in unstable installation of the tower crane lamp. If the tower crane lamp falls, it will cause danger, and the bolts need to continuously adjust the tightness of multiple bolts when used, which is not convenient enough. However, the tower crane lamps used in existing construction projects do not have components that can be conveniently and stably installed on the tower crane railings.
