Description

Technical Field

[0001] The invention relates to the technical field of foundation pit protection, in particular to a foundation pit protection device for building construction which is easy to adjust. Background Art

[0002] At present, in the process of construction, it is often necessary to excavate the corresponding foundation pit according to the amount of work. The foundation pit is a temporary project. Its function is to provide a space so that the foundation masonry work can be carried out according to the position specified in the design. In order to increase the safety factor in the foundation pit operation process and ensure the safety of underground structure construction and the surrounding environment of the foundation pit, it is necessary to adopt support, reinforcement and protection measures for the side walls of the foundation pit and the surrounding environment. Foundation pit support is to ensure the stability and safety of the surrounding area of ​​the foundation pit during underground construction. It is a temporary reinforcement and support for the foundation pit. There are many types of foundation pit support with a wide range of applications. Among them, the protective structure as one of the major items plays a huge role.

[0003] However, when the existing foundation pit protection device for construction is used, it is not convenient to adaptively adjust the angle of the protection plate according to the angle of the foundation pit, which makes it difficult for the protection plate to fit the inner wall of the foundation pit. This is not only inconvenient and not quick enough, but also affects the effect of support and protection. At the same time, when supporting, it is not convenient to extrude and reinforce the inner wall of the foundation pit and the soil on the top, which will also affect the effect of support and protection. In addition, it is not convenient to protect the soil around the top of the foundation pit. Rainwater can easily penetrate into the soil. When the protection device is removed, the inner wall of the foundation pit is prone to collapse, affecting the effect of support and protection.

[0041] The limiting mechanism includes a plurality of array-arranged jacks 909 provided on the side wall of the first rack 308, and the side wall of the first fixed block 301 is fixedly connected to a third L-shaped plate 901, the side wall of the third L-shaped plate 901 is fixedly connected to a third fixed cylinder 902, and a second piston 903 is slidably connected in the third fixed cylinder 902, the end of the second piston 903 is fixedly connected to a second connecting rod 908, and the other end of the second connecting rod 908 is fixedly connected to a second moving block 906, the side wall of the second moving block 906 is fixedly connected to a latch 907, and the side wall of the second moving block 906 is fixedly connected to two symmetrically arranged T-shaped guide rods 905, and the side wall of the T-shaped guide rod 905 is sleeved with a second connecting plate 904, The second connecting plate 904 is fixed to the side wall of the first fixed block 301, and the lower end of the first hose 206 is fixedly inserted in the end of the third fixed cylinder 902. When the movable column 205 moves, the hydraulic oil in the first fixed cylinder 204 can be squeezed, so that the hydraulic oil in the first fixed cylinder 204 enters the third fixed cylinder 902 through the first hose 206. Under the action of the hydraulic oil, the second piston 903 can be pushed. At the same time, the second movable block 906 and the second connecting plate 904 are driven to move through the second connecting rod 908, and the pin 907 is inserted into the socket 909 for limiting, so as to prevent the first rotating shaft 302 and the first protective plate 16 from rotating at will, which is more stable and reliable.

[0042] The telescopic mechanism includes two symmetrically arranged fourth sleeves 1001 fixedly connected to the bottom of the first movable plate 13, and each fourth sleeve 1001 is inserted with a fourth rod 1002, the lower end of the fourth rod 1002 is fixed to the top of the second movable plate 19, and the side wall of each fourth sleeve 1001 is sleeved with a sixth spring 1003. The first movable plate 13 is driven downward by the lifting module 12, and the second movable plate 19 and the insertion rod 20 are driven downward by the telescopic mechanism, and the insertion rod 20 is inserted into the bottom of the foundation pit. After the insertion rod 20 is completely inserted into the bottom soil of the foundation pit, when the first movable plate 13 continues to move downward, the sixth spring 1003 can be gradually compressed. At this time, the distance between the first movable plate 13 and the second movable plate 19 gradually becomes smaller.

[0043] Working principle: During use, when the foundation pit needs to be supported and protected, the movable base is pushed to move. When the side wall of the first protective plate 16 is against the top edge of the foundation pit, the first protective plate 16 can be pushed to rotate clockwise. At the same time, the rotating plate 14 is driven to rotate clockwise along the first rotating shaft 302 through the first moving block 15 and the lifting mechanism. When the first protective plate 16 is in contact with the inner wall of the foundation pit, the first movable plate 13 is driven to move downward through the lifting module 12, and the second movable plate 19 and the insertion rod 20 are driven to move downward through the telescopic mechanism, and the insertion rod 20 is inserted into the bottom of the foundation pit. At the same time, when the first rotating shaft 302 rotates, it can drive the first gear 303 to rotate, and at the same time, push the first rack 308 to move downward, and the second spring 307 is compressed.

[0044] After the insertion rod 20 is completely inserted into the bottom soil of the foundation pit, when the first movable plate 13 continues to move downward, the sixth spring 1003 can be gradually compressed. At this time, the distance between the first movable plate 13 and the second movable plate 19 gradually becomes smaller. At this time, the installation block 703 can drive the push rod 704 to slide downward along the inclined groove 702, thereby pushing the sliding block 701 to move along the guide rail 705 toward the first fixed cylinder 204. At the same time, the moving column 205 is driven to move synchronously, so that the hydraulic oil in the first fixed cylinder 204 can be squeezed, so that The hydraulic oil in the first fixed cylinder 204 enters the third fixed cylinder 902 through the first hose 206. Under the action of the hydraulic oil, the second piston 903 can be pushed. At the same time, the second connecting rod 908 drives the second moving block 906 and the second connecting plate 904 to move, and the pin 907 is inserted into the socket 909 for limiting, so as to prevent the first rotating shaft 302 and the first protective plate 16 from rotating randomly, which is more stable and reliable, thereby facilitating the adaptive adjustment of the supporting angle of the first protective plate 16, making it more convenient and quick to use, and ensuring the supporting and protective effect.

[0045] When the movable column 205 squeezes the hydraulic oil in the first fixed cylinder 204, it can enter the second sleeve 201 through the first hose 206 and the second hose 207. At this time, under the action of the hydraulic oil, the second sleeve 201 can be pushed to move away from the second sleeve rod 202. At the same time, the second half 102 is driven to move away from the first half 101. The first spring 210 is stretched, thereby driving the rotating plate 14 and the first protective plate 16 to move, and making the first protective plate 16 against the inner wall of the foundation pit, so that the soil becomes compact, which can play a reinforcing effect and make the supporting and protective effect better.

[0046] At the same time, when the moving column 205 squeezes the hydraulic oil in the first fixed cylinder 204, it can enter the second fixed cylinder 806 through the third hose 807. Under the action of the hydraulic oil, the first piston 808 can be pushed to move. At the same time, the second rack 409 is driven to move through the first connecting rod 809 and the first connecting plate 810, and the fourth spring 804 is compressed. When the second rack 409 moves, it can push the second gear 413 and the second rotating shaft 402 to rotate counterclockwise, thereby driving the winding wheel 403 to rotate, and then the pull rope 404 is wound. At this time, the sliding rod 405 and the disc 406 can move downward, and the reset spring 408 is compressed.

[0047] When the disc 406 moves downward, it can drive the pushing block 606 to move downward, and make the L-shaped frame 605 abut against the inclined surface 607, so as to push the L-shaped frame 605 and the third rack 504 to move. At the same time, the fifth spring 604 is compressed, and can push the third gear 505 and the third rotating shaft 502 to rotate counterclockwise. When the third rotating shaft 502 rotates, it can drive the rotating block 503 and the second protective plate 21 to rotate counterclockwise. At the same time, the telescopic plate 17 is deformed. When the second protective plate 21 rotates to a horizontal state, when the pushing block 606 continues to move downward, the L-shaped frame 605 can move to the side wall of the pushing block 606.

[0048] When the reset spring 408 cannot be further compressed and the pull rope 404 continues to be pulled, the first moving block 15 can be driven downward through the support block 407, and the first protective plate 16 and the second protective plate 21 can be driven downward. At the same time, the third sleeve 411 moves downward along the side wall of the third sleeve rod 410, and the third spring 412 is compressed. When the second protective plate 21 is against the top of the foundation pit, the soil around the top of the foundation pit can be squeezed to make the soil compact, thereby reinforcing the foundation pit. In addition, through the action of the second protective plate 21 and the telescopic plate 17, the soil around the top of the foundation pit can be protected to reduce the infiltration of rainwater into the interior, so that the support and protection effect is better.
