[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] The present application discloses a bridge construction platform with safety protection, including a device base 1, a support rod 2 is provided at each corner of the top surface of the device base 1, and a lifting seat 3 that can be lifted and lowered along the height direction of the support rod 2 is connected between two adjacent support rods 2; a plurality of winding shafts 9 corresponding to the lifting seat 3 are provided in the device base 1, and the winding shafts 9 are parallel to the lifting seat 3, and a blocking net 4 is connected between the corresponding winding shafts 9 and the lifting seat 3, and cleaning brushes 10 are provided on both sides of the blocking net 4 located inside the device base 1.

[0025] In the present application, the blocking net 4 is a flexible net, one end of the blocking net 4 is fixedly connected to the lifting seat 3, and the other end is fixedly connected to the winding shaft 9. The winding shaft 9 can wind up the blocking net 4 when it rotates.

[0026] The correspondence between the winding shaft 9 and the lifting seat 3 refers to the correspondence between the number and position of the two. For example, if the shape of the device base 1 is a triangle, three support rods 2 need to be set, and the number of lifting seats 3 between every two support rods 2 is also three. At this time, three winding shafts 9 also need to be set, and the winding shafts 9 are located directly below the lifting seat 3 to ensure that the blocking net 4 can be effectively wound up.

[0027] In some other embodiments, the shape of the device base 1 can be any one of a quadrilateral, a pentagon or a hexagon.

[0028] See also Figures 1 to 3 , a specific description is given with an embodiment in which the device base 1 is in a rectangular shape: a bridge construction platform with safety protection, comprising a device base 1, wherein the four ends of the upper end surface of the device base 1 are provided with support rods 2, the bottom end of the support rods 2 is located above the device base 1 and is movably connected with a lifting seat 3, a blocking net 4 is provided at the bottom end of the lifting seat 3, a winding shaft 9 is provided below the blocking net 4 and is located on the inner side of the device base 1, and cleaning brushes 10 are provided on both sides of the blocking net 4 and are located on the inner side of the device base 1.

[0029] When this application is working, by adjusting the height of the lifting seat, the blocking net can be raised or lowered with the lifting seat, which can adapt to the heights of different workers and effectively prevent the workers from being too tall or the protective mechanism from being too short. When working at high altitudes, the workers cannot be protected, which poses certain safety hazards. During the lifting process of the lifting seat, the winding shaft can reel in the blocking net, and the cleaning brush can be used to clean the blocking net during the reeling process.

[0030] The lifting platform 3 is provided with a plurality of gears 8, and a plurality of gears 8 are provided on the inner side of the support rod 2. The plurality of gears 8 are provided with gears 8 and a plurality of gears 8 are provided on the inner side of the support rod 2. The plurality of gears 8 are provided with gears 8 and a plurality of gears 8 are provided on the outer side of the support rod 2. The plurality of gears 8 are provided with gears 8 and a plurality of gears 8 are provided on the inner side of the support rod 2. The plurality of gears 8 are provided with gears 8 and a plurality of gears 8 are provided on the outer side of the support rod 2.

[0031] Furthermore, connecting blocks are provided at both ends of the winding shaft 9, one end of the connecting block is located on the inner side of the device base 1 and is provided with a rotation groove, the connecting block is inserted into the inner side of the rotation groove, and the outer side of the connecting block is located on the inner side of the rotation groove and is provided with a torsion spring, and the winding shaft 9 is movably connected to the device base 1 through the torsion spring.

[0032] Furthermore, when the torsion spring is in the natural state, the height of the lifting seat 3 is lower than when the torsion spring is in the stretched state. This design allows the torsion spring to tighten the blocking net 4 at all times, so that when the lifting seat 3 descends, the blocking net 4 will be rolled up onto the winding shaft 9 without providing additional winding power.

[0033] The cleaning brush 10 is an L-shaped cleaning brush. One end of the cleaning brush 10 is located on the inner side of the device base 1 and is provided with a spring groove 11. The inner side of the spring groove 11 is provided with a spring 12. The spring groove 11 and the spring 12 are fixedly connected by bolts. The cleaning brush 10 is movably connected to the device base 1 through the spring 12, and then when the lifting seat 3 is lifted and lowered, the winding shaft 9 winds up the blocking net 4. The cleaning brush 10 is an L-shaped cleaning brush. The cleaning brush 10 fits against the blocking net 4, so that the blocking net 4 is cleaned during the process of winding up the blocking net 4.

[0034] In a further embodiment, the height of the barrier net 4 when fully extended is 85-130 cm. The top of the protective barrier net can reach the belly of the staff to effectively protect the staff, and this design can adapt to the protection of staff of different heights. More preferably, the height of the barrier net 4 when half extended is 80 cm, and the height when fully extended is 130 mm.

[0035] To sum up, when the bridge construction platform is in use, first check whether all components are intact. After the inspection is completed, turn on the power and start the device. When one of the screw rods 5 rotates, one of the screw rods 5 drives the other three screw rods 5 to rotate simultaneously through the transmission chain 6. When all the screw rods 5 rotate, the staff can adjust the height of the lifting seat 3 according to the height of the workers, which effectively prevents the working height from being too high or the height of the protective mechanism from being too short. When working at high altitudes, the workers cannot be protected, which poses certain safety hazards. In the process of lifting the lifting seat 3, the winding shaft 9 winds up the blocking net 4. The cleaning brush 10 is an L-shaped plug, and the cleaning brush 10 fits with the blocking net 4, so that the blocking net 4 is cleaned during the process of winding up the blocking net 4.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
