Description

Technical Field

[0001] This invention belongs to the field of support technology, and particularly relates to a deep foundation pit support device for construction. Background Technology

[0002] Excavation pit support refers to the measures taken to support, reinforce, and protect the sidewalls and surrounding environment of the excavation pit to ensure the safety of underground structure construction and the surrounding environment. The slopes set during pit excavation must meet safety requirements. The methods of pit wall support and reinforcement measures for important underground pipelines must comply with the requirements of the specialized construction plan and the excavation pit support structure design plan. If local deformation occurs in the support facilities, a solution should be proposed in conjunction with the designers, and corresponding measures should be taken promptly for adjustment and reinforcement.

[0003] Foundation pit support engineering includes many closely related links such as retaining, support, waterproofing, dewatering, and excavation. Failure of any one of these links will lead to the failure of the entire project.

[0004] Most existing support devices directly limit the support angle and can only support the sidewalls of foundation pits with a fixed angle. They are difficult to adapt to sidewalls with different inclination angles, have a narrow range of applications, and poor adaptability. Furthermore, adjustable angle support devices still require a fixed angle. After the angle is adjusted, the angle adjustment part still needs to be fixed manually, which is time-consuming and labor-intensive. They cannot automatically lock the device, have a low degree of automation, and are not easy to use. Summary of the Invention

Detailed Implementation

[0037] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0038] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0039] like Figure 1 As shown in the embodiment of the present invention, a deep foundation pit support device for construction includes: a first support plate 1 and a second support plate 2, and positioning nails 3 for fixing the first support plate 1 to the ground, wherein the first support plate 1 and the second support plate 2 are rotatably connected. The deep foundation pit support device for construction further includes:

[0040] A drive mechanism 4 is disposed between the first support plate 1 and the second support plate 2. The drive mechanism 4 is used to control the second support plate 2 to flip and contact the side wall of the pit.

[0041] The locking mechanism 5 is disposed on the second support plate 2 and connected to the driving mechanism 4. After the driving mechanism 4 controls the second support plate 2 to contact the side wall of the pit, the locking mechanism 5 is used to restrict the position of the driving mechanism 4.

[0042] When using this deep foundation pit support device, the first support plate 1 is first fixed to the ground near the pit wall by the positioning nail 3. Then, the drive mechanism 4 can control the rotation of the second support plate 2 until the second support plate 2 contacts the side wall of the foundation pit. This method can adapt to foundation pit side walls of various angles and has strong adaptability. After the second support plate 2 contacts the side wall of the foundation pit, the locking mechanism 5 will be automatically driven to operate. The locking mechanism 5 will directly lock the drive mechanism 4 to ensure the stability of the second support plate 2 during the support process. When it is necessary to release the support, simply pull out the positioning nail 3, move the first support plate 1, and move the second support plate 2 away from the side wall. At this time, the locking mechanism 5 will automatically release the lock, and the second support plate 2 can be stored. It is convenient to use, simple to operate, highly automated, and can adapt to foundation pit side walls of various angles.

[0043] like Figures 1 to 6 As shown, in this embodiment of the invention, the driving mechanism 4 includes:

[0044] The first support 41 and the second support 42 are respectively disposed on the first support plate 1 and the second support plate 2. The first support 41 is provided with a main motor 43, and the output end of the main motor 43 is connected to a first push rod 44.

[0045] The second push rod 45 is rotatably mounted on the second support 42, and the first push rod 44 and the second push rod 45 are rotatably connected to each other via a rotating shaft 46.

[0046] In use, the main motor 43 drives the first push rod 44 to rotate, and then through the cooperation between the first push rod 44 and the second push rod 45, drives the second support plate 2 to rotate until the second support plate 2 contacts the side wall of the pit, thus achieving the support effect.

[0047] like Figures 1 to 6 As shown, in this embodiment of the invention, the locking mechanism 5 includes:

[0048] The first slot 51 and the second slot 52 are respectively provided on the first push rod 44 and the second push rod 45, and the rotating shaft 46 passes through the first slot 51 and the second slot 52;

[0049] A rotating disk 53 is disposed inside the first slot 51 and is rotatably connected to the rotating shaft 46. A screw 54 is disposed inside the rotating disk 53, and one end of the screw 54 is slidably connected to an elastic telescopic rod 55 by a spring.

[0050] A plurality of slots 56 are evenly disposed on the inner walls of the first slot 51 and the second slot 52, and the slots 56 cooperate with the elastic telescopic rod 55.

[0051] A control and operation component is disposed inside the second push rod 45, and the control and operation component is used to drive the screw 54 to move.

[0052] like Figures 1 to 6 As shown, in this embodiment of the invention, one end of the elastic telescopic rod 55 is connected to a universal ball 57.

[0053] like Figures 1 to 6 As shown, in this embodiment of the invention, the control operation component includes:

[0054] A groove 58 is formed on one side of the second support plate 2. A positioning post 59 is provided inside the groove 58, and a support plate 510 is slidably arranged on the positioning post 59.

[0055] A return spring 511 is also fitted on the positioning post 59, and the return spring 511 is connected to the support plate 510.

[0056] A toothed plate 512 is disposed on the side of the support plate 510. A first gear 513 is rotatably connected inside the second support plate 2. The first gear 513 and the toothed plate 512 cooperate with each other.

[0057] A transmission assembly, mounted on the second push rod 45, is used to control the rotation of the rotating disk 53.

[0058] like Figures 1 to 6 As shown, in this embodiment of the invention, the transmission assembly includes:

[0059] A number of connecting discs 514 are disposed on the second support plate 2 and the second push rod 45, and transmission belts 515 are sleeved between the connecting discs 514, between the connecting discs 514 and the first gear 513, and between the connecting discs 514 and the rotating disc 53.

[0060] A threaded sleeve 516 is rotatably connected inside the rotating disk 53, and the threaded sleeve 516 is threadedly engaged with the screw 54.

[0061] A second gear 519 is mounted on the threaded sleeve shaft 516, and a gear ring 520 is also mounted on the inner wall of the first slot 51. The gear ring 520 cooperates with the second gear 519.

[0062] like Figures 1 to 6 As shown, in this embodiment of the invention, a limiting groove 517 is provided on the side of the screw 54, and a limiting strip 518 is provided on the inner wall of the rotating disk 53. The limiting groove 517 and the limiting strip 518 cooperate with each other.

[0063] In use, when the second support plate 2 contacts the side wall of the pit, it presses the support plate 510 into the plate groove 58, and drives the first gear 513 to rotate through the toothed plate 512. The first gear 513 then drives the rotating disk 53 to rotate through the transmission belt 515 and several connecting discs 514. When the rotating disk 53 rotates, it drives the second gear 519 to rotate along the toothed ring 520. The toothed ring 520 drives the second gear 519 to rotate continuously, which in turn drives the threaded sleeve shaft 516 to rotate. Since the limit strip 518 restricts the rotation of the screw 54, the threaded sleeve... When shaft 516 rotates, it pushes screw 54 outward, causing elastic telescopic rod 55 to insert into locking groove 56, thus limiting the first push rod 44 and the second push rod 45. At the same time, if elastic telescopic rod 55 contacts the inner wall of the first slot 51 or the second slot 52 during the movement but does not enter locking groove 56, the elastic extension and retraction effect of universal ball 57 and elastic telescopic rod 55 can control the rotating disk 53 to continue rotating until it moves to locking groove 56, at which point elastic telescopic rod 55 will directly spring into locking groove 56 to achieve positioning.

[0064] In summary, when using this deep foundation pit support device for construction, the first support plate 1 is first fixed to the ground near the pit wall using positioning nails 3. Then, the drive mechanism 4 can control the rotation of the second support plate 2 until the second support plate 2 contacts the pit sidewall. This method can adapt to pit sidewalls of various angles and has strong adaptability. After the second support plate 2 contacts the pit sidewall, the locking mechanism 5 will automatically drive to operate, and the locking mechanism 5 will directly lock the drive mechanism 4 to ensure the stability of the second support plate 2 during the support process. When it is necessary to release the support, simply pull out the positioning nails 3, move the first support plate 1, and move the second support plate 2 away from the sidewall. At this time, the locking mechanism 5 will automatically release the lock, and the second support plate 2 can be stored. It is convenient to use, simple to operate, highly automated, and can adapt to pit sidewalls of various angles.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
