[0022] Reference Figures 1-5 As shown, this utility model provides a technical solution: a foundation pit edge protection support, including a protective frame 1, a protective net 2 fixedly connected to the surface of the protective frame 1, a column 3 fixedly connected to the surface of the protective frame 1, a counterweight device 4 provided on the surface of the protective frame 1, the counterweight device 4 including a fixing block 42, the fixing block 42 being fixedly connected to the protective frame 1, a long plate 45 being snapped into the fixing block 42, a rotating rod 48 being rotatably connected to the long plate 45, a cylinder 41 being fixedly connected to one end of the rotating rod 48, a fixing plate 44 being fixedly connected to the surface of the fixing block 42, a first screw 43 being threaded into the fixing plate 44, the first screw 43 penetrating the long plate 45, a limiting plate 49 being fixedly connected to the surface of the long plate 45, a fixing pin 47 being slidably connected to the surface of the limiting plate 49, the fixing pin 47 being slidably connected to the rotating rod 48, a rope 46 being fixedly connected to the surface of the fixing pin 47, and the other end of the rope 46 being fixedly connected to the long plate 45.

[0023] Reference Figures 1-5 As shown, specifically, the surface of the protective frame 1 is provided with a fixing device 5, which includes a U-shaped plate 501. The U-shaped plate 501 is fixedly connected to the protective frame 1. A rotating shaft 502 is rotatably connected to the surface of the U-shaped plate 501. A mounting frame 503 is fixedly connected to the surface of the rotating shaft 502. An L-plate 511 is fixedly connected to the surface of the mounting frame 503. A pull rod 508 is slidably connected to the surface of the L-plate 511. A limit block 509 is fixedly connected to one end of the pull rod 508. A spring 510 is sleeved on the arc surface of the pull rod 508. The two ends of the spring 510 are fixedly connected to the L-plate 511 and the limit block 509, respectively. The limit block 509 is slidably connected to the mounting frame 503. A second screw 505 is threadedly connected to the surface of the mounting frame 503. A circular plate 506 is fixedly connected to the surface of the second screw 505. A needle 507 is fixedly connected to the lower surface of the circular plate 506. A guide plate 504 is fixedly connected to the surface of the mounting frame 503.

[0024] The working principle is as follows: During the foundation pit construction, the long plate 45 is first placed under the fixing block 42. Then, by rotating the first screw 43 on the surface of the fixing plate 44, the first screw 43 passes through the long plate 45 through the thread to fix the long plate 45, thus facilitating disassembly by the workers. Next, a weighted object is placed inside the cylinder 41, thereby lowering the center of gravity of the protective frame 1 and enabling the protective frame 1 to be stably protected around the foundation pit. Then, the fixing pin 47 on the surface of the limiting plate 49 slides through the rotating rod 48. The fixing pin 47 can limit the position of the cylinder 41 and prevent the cylinder 41 from rotating during use. The rope 46 on the surface of the fixing pin 47 can prevent the fixing pin 47 from being lost. When it is necessary to empty the contents of the cylinder 41, pull the fixing pin 47 upward and then rotate the cylinder 41. At this time, the contents of the cylinder 41 will be emptied. By setting the counterweight device 4, the center of gravity of the protective frame 1 is lowered, the stability of the protective frame 1 is improved, and the situation of the protective frame 1 tipping over due to uneven ground at the construction site is avoided.

[0025] When assembling multiple edge protection brackets, first rotate the rotating shaft 502 on the surface of the U-shaped plate 501. The rotating shaft 502 will drive the mounting frame 503 to rotate. After adjusting the rotation angle, rotate the second screw 505. The second screw 505 will drive the circular plate 506, which will drive the spikes 507 to insert into the ground. The spikes 507 increase the contact area with the ground, which can restrict the position of the mounting frame 503, thereby restricting the rotation path of the rotating shaft 502. Then, slide the column 3 along the surface of the guide plate 504. The guide plate 504 facilitates the installation of the column 3 into the mounting frame 503. Within 03, when one side of the column 3 contacts the limiting block 509, the limiting block 509 will drive the pull rod 508 to slide along the surface of the L plate 511. At this time, the spring 510 begins to contract. When the other side of the column 3 contacts the limiting block 509, the spring 510 begins to rebound with its own elastic force. At this time, the column 3 can be fixed in the mounting frame 503. By setting the fixing device 5, it is possible to easily connect, install and disassemble the edge protection bracket. By utilizing the rotation between the protective frame 1 and the mounting frame 503, the angle between multiple protective frames 1 can be adjusted according to the actual situation of the construction site, thereby improving the practicality of the protective frame 1.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
