Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically a safety protection device for foundation pits in building roads. Background Technology

[0002] Due to the development of my country's social economy, the urbanization process has been greatly promoted, and the country has also increased its investment in road construction. Various forms and uses of underground space have been developed and utilized in road construction. In addition, the scale and number of underground projects have also increased significantly, and deep foundation pits for road projects have emerged. Since the construction area of ​​road foundation pit projects often involves personnel access, the safety protection work of road foundation pits is particularly important.

[0003] However, existing safety protection devices for construction road foundation pits have the following drawbacks:

[0004] (1) Existing safety protection devices for building road foundation pits have weak rapid installation function. Because the traditional protection device installation process is cumbersome and takes a long time, it increases the workload of manual labor and reduces the installation efficiency.

[0005] (2) The existing safety protection devices for building road foundation pits have weak stability. When the wind is strong, the position of the protection device is prone to shift and it is easy to tilt and fall, resulting in inadequate protection performance of the device. Utility Model Content

During the connection process, the connecting slider 204 slides inside the connecting groove 203. At the same time, the connecting slider 204 limits the movement position of the protective rod 201. When the connecting slider 204 is in contact with the connecting groove 203, the connecting screw 206 is rotated to fix the position of the protective rod 201, thereby stably connecting the protective rod 201 and the second column 207.

[0026] The fixing component 3 consists of a base 301, a storage frame 302, a telescopic rod 303, a spring 304, a clamping plate 305, a counterweight 306, an extension plate 307, and a fixing screw 308. The base 301 is fixedly connected to the bottom of the first column 1. The storage frame 302 is provided on the inner wall of the base 301. The telescopic rod 303 is fixedly connected to the inner wall of the storage frame 302. A spring 304 is sleeved on the outer surface of the telescopic rod 303. A clamping plate 305 is fixedly connected to one end of the telescopic rod 303. A counterweight 306 is provided on the inner bottom wall of the storage frame 302. A clamping plate 307 is fixedly connected to one side of the base 301. The extension plate 307 has a fixed screw 308 connected to its internal thread. The storage frame 302 is pulled out from the base 301, and the counterweight 306 is placed in the storage frame 302. After placement, the spring 304 rebounds, causing the telescopic rod 303 to extend, which in turn causes the clamping plate 305 to clamp the counterweight 306, keeping the position of the counterweight 306 stable. Then, the storage frame 302 is returned to its original position in the base 301. Then, the fixed screw 308 is rotated, and at the same time, the extension plate 307 limits the position of the fixed screw 308. When the fixed screw 308 is rotated to extend into the ground, the position of the device can be further fixed.

[0027] The inner sidewall of the connecting frame 205 is provided with a connecting groove. One side of the connecting slider 204 is connected to the connecting frame 205 through the connecting groove. The connecting groove enables a stable connection between the connecting frame 205 and the connecting slider 204.

[0028] The inner side wall of the storage frame 302 is provided with a first fixing groove. One end of the spring 304 is connected to the storage frame 302 through the first fixing groove. One side of the clamping plate 305 is provided with a second fixing groove. The side of the spring 304 near the counterweight 306 is connected to the clamping plate 305 through the second fixing groove. Through the connection between the spring 304, the storage frame 302 and the clamping plate 305, the storage frame 302 supports and fixes one end of the spring 304.

Then pull the storage frame 302 out of the base 301. The counterweight 306 is placed in the storage frame 302. After placement, the spring 304 rebounds, causing the telescopic rod 303 to extend, which in turn causes the clamping plate 305 to clamp the counterweight 306, keeping the position of the counterweight 306 stable. Then, the storage frame 302 is returned to its original position in the base 301. Then, the fixing screw 308 is rotated, and at the same time, the extension plate 307 limits the position of the fixing screw 308. When the fixing screw 308 is rotated to extend into the ground, the position of the device can be further fixed.

[0034] The second step: The connecting slots can stably connect the connecting frame 205 and the connecting slider 204. The spring 304 is connected to the storage frame 302 and the clamping plate 305. The storage frame 302 supports and fixes one end of the spring 304. When the spring 304 extends and retracts, it will drive the clamping plate 305 to move accordingly. Each column surface is provided with eight connecting frames 205, four on the top and four on the bottom, and they are evenly distributed on the column surface.

[0035] Third step: The first column 1 and the second column 207 are perpendicular to each other to maintain their own stability. When the fixing screw 308 is rotated until it is in contact with the threaded groove, the threaded groove limits the fixing screw 308 to prevent it from slipping.
