Description

Technical Field

[0001] The utility model relates to the technical field of safety protection devices, in particular to a foundation pit safety protection device. Background Art

[0002] As we all know, there are many kinds of pipelines installed at the bottom of the highway. During the maintenance of the pipelines, a foundation pit is often dug first. The foundation pit is a soil pit excavated at the foundation design location according to the base elevation and foundation plane size. Before excavation, the excavation plan should be determined based on geological and hydrological data and the situation of nearby buildings on site, and waterproofing and drainage work should be done. Due to the long project period and the certain depth of the foundation pit or foundation trench, personnel usually build guardrails at the slope of the foundation pit. The current guardrails include support rods, and the bottom of the support rods is welded with a chassis. There are multiple fixing holes on the chassis, which are fixed to the ground by expansion bolts. Square tubes of different heights are welded between two adjacent support rods to form a fixed frame. Color steel plates are installed on the fixed frame by self-tapping screws for folding protection. The installation process of this device takes a long time and is inconvenient to remove after use.

[0003] To this end, we developed a foundation pit safety protection device. Utility Model Content

[0022] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0023] Please refer to Figures 1-4, for the present utility model, a foundation pit safety protection device, includes a chassis 1. A number of chassis 1 are provided. At the top of each chassis 1, a fixed rod 3 is fixedly connected. At the top of each fixed rod 3, a threaded rod 4 is fixedly connected. On each threaded rod 4, a fixing cap 5 is installed. On each fixed rod 3, a plurality of connecting components are installed, and on each connecting component, a protection component is installed.

[0024] The connecting component includes a connecting column 6. A through hole 8 is opened through the upper and lower parts of the connecting column 6. A plurality of clamping grooves 7 are evenly opened on the outer side of the connecting column 6.

[0025] The protection component includes a baffle 9. At both ends of the baffle 9, clamping blocks 10 are fixedly connected.

[0026] The cross-section of the fixed rod 3 is square. The insertion hole 8 matches the fixed rod 3 and is connected by sliding, which can prevent the connecting column 6 from rotating on the fixed rod 3 and improve stability.

[0027] The height of the fixed rod 3 is equal to the sum of the heights of a plurality of connecting columns 6 on the fixed rod 3. A threaded hole is opened at the bottom of the fixing cap 5, and the threaded hole is threadedly connected with the threaded rod 4. The fixing cap 5 is used to fix a plurality of connecting columns 6 on the fixed rod 3.

[0028] The clamping groove 7 is in a T shape, and the clamping groove 7 matches the clamping block 10, which can prevent the clamping block 10 from sliding out of the clamping groove 7.

[0029] In summary, when using this foundation pit safety protection device, place the chassis 1 and the fixed rod 3 according to the shape of the foundation pit. Insert a connecting column 6 into each fixed rod 3, then insert the clamping blocks 10 on both sides of the baffle 9 into the corresponding clamping grooves 7, then insert another connecting column 6, and insert the clamping block 10 of a baffle 9 into the clamping groove 7, and so on until the stacked height of the connecting columns 6 is the same as the height of the fixed rod 3. Use expansion bolts to fix the chassis 1 through the fixing holes 2, and then install the fixing caps 5 on each threaded rod 4, so as to conveniently install the construction of the protection device.
