DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present 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 present utility model.

[0022] Please refer to Figures 1-5 , a safety operation protection device for deep foundation pits in building construction in this embodiment, includes an installation bracket 1. A plurality of fastening bolts penetrating to the left side are threadedly installed on the right side of the installation bracket 1. The installation bracket 1 can be fixed on the side wall of the deep foundation pit through the plurality of fastening bolts. At this time, the installation bracket 1 plays a supporting role. A bracket 2 is fixedly installed on the top of the installation bracket 1, and a gravel dumping structure is arranged on the top of the bracket 2.

[0023] The gravel dumping structure includes a stress plate 3 rotatably installed on the top of the bracket 2. The installed stress plate 3 catches the gravel to protect the operators. The rotation connection between the bracket 2 and the stress plate 3 is located at one end close to the back of the bracket 2, aiming to facilitate the stress plate 3 to flip on the top of the bracket 2.

[0024] Two connecting blocks 4 are fixedly installed at the bottom of the stress plate 3. Both of the two connecting blocks 4 are located at the waist position of the stress plate 3. One end link 5 is rotatably installed on the outer sides of both of the two connecting blocks 4. The bottom of both of the two one - end links 5 is rotatably installed with a two - end link 6. The one - end link 5 and the two - end link 6 are connected in a V - shaped distribution. When driving the two two - end links 6 to rotate forward, the stress plate 3 can be pushed to rotate clockwise on the top of the bracket 2 through the two one - end links 5. At this time, the gravel caught on the top of the stress plate 3 will automatically slide to the outside. When driving the two two - end links 6 to rotate reversely, the stress plate 3 can be driven to rotate counterclockwise on the top of the bracket 2 through the two one - end links 5, so that the stress plate 3 is reset.

[0025] Two working grooves 7 penetrating to the top are opened at the bottom of the bracket 2. The two one - end links 5 and the two - end links 6 are respectively located inside the two working grooves 7. The width of the working groove 7 is greater than the width of the one - end link 5 and the two - end link 6, which is convenient for the one - end link 5 and the two - end link 6 to move inside the bracket 2. A dumping driving structure is arranged at the bottom of the bracket 2.

[0026] The dumping driving structure includes two limit rotating seats 8 fixedly installed at the bottom of the bracket 2. The two limit rotating seats 8 are respectively located outside the two working grooves 7. A transmission rod 9 is rotatably installed inside the two limit rotating seats 8. The transmission rod 9 penetrates to the right side of the limit rotating seat 8. The transmission rod 9 is supported to rotate at the bottom of the bracket 2 through the two limit rotating seats 8.

[0027] On the right side of the transmission rod 9, a first gear 10 is fixedly installed. The first gear 10 is located on the right side of the limit rotating seat 8. At the bottom of the bracket 2, a DC motor 11 is fixedly installed. The output end of the DC motor 11 faces left. The DC motor 11 can be driven forward and backward. A second gear 12 is fixedly installed at the output end of the DC motor 11. The second gear 12 is meshed and installed at the bottom of the first gear 10. When the DC motor 11 drives the second gear 12 to rotate, it can drive the transmission rod 9 and the two second connecting rods 6 installed outside the transmission rod 9 to rotate synchronously through the first gear 10. At the bottom of the bracket 2, two support platforms 13 penetrating through to its top are fixedly installed. Both of the two support platforms 13 are located at one end close to the front of the bracket 2. Rubber pads are fixedly installed on the tops of the two support platforms 13. The bottom of the force-bearing plate 3 is supported by the two support platforms 13. At this time, the two installed rubber pads play a role of buffering and protecting the bottom of the force-bearing plate 3.

[0028] The working principle of the above embodiment is as follows:

[0029] When in use, the device is fixed on the side wall of the deep foundation pit by using multiple fastening bolts. At this time, the operator can work in the deep foundation pit. The installed force-bearing plate 3 can catch the gravel and foreign objects falling on the side wall of the deep foundation pit, so as to provide safety protection for the operator. When it is necessary to clean the foreign objects caught by the force-bearing plate 3, first evacuate the operating personnel, and then the DC motor 11 drives the second gear 12 to rotate forward. Through the first gear 10, it drives the two second connecting rods 6 installed outside the transmission rod 9 to rotate synchronously. The two second connecting rods 6 rotate forward and push the force-bearing plate 3 to rotate clockwise on the top of the bracket 2 through the two first connecting rods 5. At this time, the gravel caught on the top of the force-bearing plate 3 automatically slides to the outside. After the gravel and foreign objects on the top of the force-bearing plate 3 are cleaned, control the DC motor 11 to drive the two second connecting rods 6 to rotate reversely to drive the force-bearing plate 3 to reset.
