Description

Technical Field

[0001] This utility model relates to the field of housing construction technology, and in particular to a support frame for the maintenance of foundation pits in housing construction. Background Technology

[0002] Housing construction is a complex and systematic project, referring to the construction of houses and other buildings on land where infrastructure has been completed, using a series of specialized technologies and processes. In the entire housing construction process, foundation engineering is a crucial basic link, and foundation pit support equipment is a key component of the building foundation project. The role of foundation pit support equipment cannot be underestimated; it acts as a "guardian" of the building. During foundation pit excavation, it effectively supports the surrounding soil, preventing soil collapse, and also acts as a water barrier, preventing groundwater from affecting the foundation pit construction. Its construction quality and effectiveness directly affect the stability of the building foundation. If the construction quality of the foundation pit support equipment is poor, such as insufficient strength of the support structure or inadequate anchoring force, it may lead to excessive deformation of the surrounding soil, or even cause a collapse. This will not only cause serious damage to the building under construction, leading to project delays and economic losses, but more seriously, it may endanger the lives and health of on-site construction workers and nearby residents. For this reason, people attach great importance to foundation pit support equipment. From equipment selection and installation to subsequent maintenance and monitoring, every link is strictly controlled to ensure that the foundation pit support equipment can play its due role and provide a solid and reliable guarantee for building construction.

[0003] Existing foundation pit support equipment is fixed and cannot be adjusted in height according to the actual depth of the foundation pit, reducing its flexibility. Furthermore, most existing support devices lack adjustable support angles, limiting their application to specific environments and thus reducing their overall flexibility and efficiency. To address these issues, this application proposes a support frame for foundation pit maintenance in building construction. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a support frame for the maintenance of foundation pits in building construction. By starting the first motor, a bidirectional worm gear is driven to rotate. The rotation of the bidirectional worm gear meshes with the worm wheel, causing the worm wheel to rotate. The rotation of the worm wheel drives the support rod to rotate, causing the base plate to slide. The height of the support plate can be adjusted, thereby improving the flexibility of the foundation pit support equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A support frame for the maintenance of foundation pits in building construction includes a base. A base plate is slidably connected to the top side of the inner wall of the base. Multiple support rods are rotatably connected to the inner wall of the base. The adjacent sides of the multiple support rods are slidably connected to the left and right sides of the base plate. The bottom left sides of the two support rods on the left are connected by a transmission assembly for adjusting the rotation of the support rods. A connecting rod is rotatably connected to the front side of the base plate. A support plate is fixedly connected to the outer wall of the connecting rod. A groove is formed at the top of the base plate. A slider is slidably connected to the inner wall of the groove. The inner wall of the slider is connected to the outer wall of the connecting rod by a limiting assembly for adjusting the rotation of the connecting rod. A support block is rotatably connected to the top of the slider. The inner wall of the support plate is rotatably connected to the top left and right sides of the support block.

[0007] Furthermore, the transmission assembly includes worm gears fixedly connected to the bottom left side of the two left support rods, and the bottom of the two worm gears are meshed with a bidirectional worm.

[0008] Furthermore, a first motor is fixedly connected to the front side of the base, and the front end of the bidirectional worm gear is fixedly connected to the drive end of the first motor.

[0009] Furthermore, two limiting rods are fixedly connected to the bottom of the base plate, and the outer wall of the limiting rods is slidably connected to the bottom side of the inner wall of the base.

[0010] Furthermore, the limiting component includes a threaded rod rotatably connected to the inner wall of the slide groove, the outer wall of the threaded rod being threadedly connected to the inner wall of the slider, a first bevel gear being fixedly connected to the front end of the threaded rod, and a second bevel gear being fixedly connected to the outer wall of the connecting rod.

[0011] Furthermore, the outer wall of the second bevel gear meshes with the outer wall of the first bevel gear.

[0012] Furthermore, a second motor is fixedly connected to the rear side of the base plate, and the rear end of the threaded rod is fixedly connected to the drive end of the second motor.

[0013] Furthermore, multiple plugs are fixedly connected to both the bottom of the base and the front of the support plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the first motor is started to drive the bidirectional worm gear to rotate. The bidirectional worm gear rotates and meshes with the worm wheel to make the worm wheel rotate. The rotation of the worm wheel drives the support rod to rotate, causing the base plate to slide.

Worm gears 8 are fixedly connected to the bottom left side of the two support rods 6 on the left side. The bottom of the two worm gears 8 are meshed with a bidirectional worm 9. The rotation of the bidirectional worm 9 meshes with the worm gears 8, causing the worm gears 8 to rotate, which in turn drives the support rods 6 to rotate. A first motor 4 is fixedly connected to the front side of the base 1. The front end of the bidirectional worm 9 is fixedly connected to the driving end of the first motor 4, and the first motor 4 drives the bidirectional worm 9 to rotate. Two limiting rods 7 are fixedly connected to the bottom of the base plate 2. The outer wall of the limiting rods 7 is slidably connected to the bottom side of the inner wall of the base 1, stabilizing the sliding of the base plate 2.

[0025] Reference Figure 1 , Figure 3 and Figure 4 A connecting rod 10 is rotatably connected to the front side of the base plate 2. A support plate 3 is fixedly connected to the outer wall of the connecting rod 10. Rotation of the connecting rod 10 causes the support plate 3 to rotate. A sliding groove is opened at the top of the base plate 2. A slider 11 is slidably connected to the inner wall of the sliding groove. A threaded rod 12 is rotatably connected to the inner wall of the sliding groove. The outer wall of the threaded rod 12 is threadedly connected to the inner wall of the slider 11. Rotation of the threaded rod 12 causes the slider 11 to slide. A first bevel gear 14 is fixedly connected to the front end of the threaded rod 12. A second bevel gear 15 is fixedly connected to the outer wall of the connecting rod 10. The outer wall of the second bevel gear 15 meshes with the outer wall of the first bevel gear 14. The threaded rod 12 drives the first bevel gear 14 to rotate and meshes with the second bevel gear 15, which in turn drives the connecting rod 10 to rotate. A second motor 5 is fixedly connected to the rear side of the base plate 2. The rear end of the threaded rod 12 is fixedly connected to the driving end of the second motor 5, and the second motor 5 drives the threaded rod 12 to rotate.
