Description

Technical Field

[0001] The utility model belongs to the technical field of support frames, and particularly relates to a support frame for water conservancy and hydropower engineering construction. Background Technique

[0002] During the construction of water conservancy and hydropower projects, the construction environment is often complex and diverse, and different construction scenarios and geological conditions pose extremely high requirements for the performance of support frames. For example, when excavating a foundation pit with an irregular shape, the top of the traditional support frame is usually a fixed plane or a simple geometric shape, which is difficult to closely fit the concave and convex contours of the foundation pit, resulting in gaps between the support frame and the foundation pit wall, unable to effectively disperse the soil pressure, easily causing local soil collapse, and there are relatively large safety hazards;

[0003] In the construction of tunnels with complex cross-sections, since the cross-sectional shape of the tunnel may be horseshoe-shaped, circular or other irregular shapes, the support frame with a fixed shape cannot perfectly fit the tunnel cross-section, resulting in uneven distribution of the support force and insufficient support strength in some areas, seriously affecting the construction safety and project quality. In addition, the traditional support frame has poor versatility. In different construction scenarios, the construction unit needs to frequently replace different types of support frames, which not only increases the equipment procurement cost, but also prolongs the construction preparation time, reduces the overall construction efficiency, and also causes waste of human and material resources;

[0004] Therefore, a support frame for water conservancy and hydropower engineering construction is needed to solve the above problems. Content of the Utility Model

[0009] As a preferred solution, the threaded rod is shaped like a T, and a turntable is connected to the bottom of the threaded cylinder.

[0010] As a preferred solution, two second limiting strips are connected to the top of the rotating plate.

[0026] The following describes the present utility model in further detail with reference to embodiments.

[0027] The following embodiments are used to illustrate the present utility model, but cannot be used to limit the protection scope of the present utility model. The conditions in the embodiments can be further adjusted according to specific conditions. Any simple improvement of the method of the present utility model under the premise of the concept of the present utility model belongs to the protection scope required by the present utility model.

[0028] Embodiment 1

[0029] As Figures 1 - 5 shown, an embodiment of the present utility model provides a support frame for water conservancy and hydropower engineering construction, including a support assembly 1, an adjusting assembly 2, a support component 3, and an elastic component 4. The support assembly 1 includes a support frame 11, which provides a stable support foundation for the entire support frame. The support frame 11 is respectively hinged to four rotating blocks 12 through four pins, enabling the rotating blocks 12 to rotate flexibly around the pins, creating conditions for adjusting the shape of the top of the support frame. The tops of the four rotating blocks 12 are all connected with limit frames 13, and the limit frames 13 play a role in limiting and guiding the movement of the support component 3;

[0030] The adjusting assembly 2 includes a threaded cylinder 21, which is rotatably connected inside the support frame 11, and a threaded rod 22 is threadedly connected inside the threaded cylinder 21;

[0031] The support component 3 includes a movable plate 31. The bottom of the movable plate 31 is connected to the top end of the threaded rod 22. Both sides of the movable plate 31 are respectively hinged to two rotating plates 32 through pin rods 35. The bottoms of the rotating plates 32 are connected with two first limit strips 33, and the limit frames 13 are slidably connected outside the first limit strips 33.

[0032] In this embodiment, first, place this support frame at a predetermined position at the bottom of the foundation pit. Through the threaded holes 52 at the bottom of the connection frame 51, use bolts to fix the support frame to the bottom of the foundation pit or tunnel to ensure its stability.

[0033] The construction worker rotates the turntable 23 of the adjustment assembly 2 to drive the threaded barrel 21 to rotate. The threaded rod 22 then moves upward, pushing the movable plate 31 to rise. During the rising process of the movable plate 31, the rotating plate 32 is driven to rotate around the pin rod 35 through the pin rod 35. The first limiting strip 33 at the bottom of the rotating plate 32 slides in the T-shaped through groove of the limiting frame 13 to ensure the stable movement of the rotating plate 32. As the rotating plate 32 rotates, the shape of the top of the support frame gradually changes until it closely fits the irregular contour of the foundation pit.

[0034] As Figure 2 shown, specifically, the shape of the threaded rod 22 is set as T-shaped, and the bottom of the threaded barrel 21 is connected with a turntable 23.

[0035] In this embodiment, by rotating the turntable 23, the threaded barrel 21 can be driven to rotate. Since the threaded rod 22 is threadedly connected with the threaded barrel 21, the rotation of the threaded barrel 21 will cause the threaded rod 22 to move up and down axially, thereby providing power for the lifting of the support assembly 3.

[0036] As Figure 3 and Figure 4 shown, specifically, two second limiting strips 34 are connected to the top of the rotating plate 32; the cross-sectional shapes of the first limiting strip 33 and the second limiting strip 34 are both set as T-shaped; the shape of the limiting groove 42 is set as T-shaped, and a T-shaped through groove is opened in the limiting frame 13.

[0037] In this embodiment, due to the sliding fit between the T-shaped first limiting strip 33 and the T-shaped through groove opened in the limiting frame 13, the stable movement of the rotating plate 32 is ensured. Since the second limiting strip 34 is set as T-shaped, it is used to cooperate with the elastic component 4.

[0038] As Figure 5 shown, specifically, it further includes a connection component 5. The connection component 5 includes a connection frame 51. The bottom of the connection frame 51 is connected with the support frame 11, and a plurality of threaded holes 52 are opened at the bottom of the connection frame 51.

[0039] In this embodiment, by installing bolts in the threaded holes 52, the support frame can be firmly connected to the construction site such as the bottom of the foundation pit or the ground of the tunnel, ensuring the stability of the support frame during use.

[0040] Embodiment 2

[0041] Please refer to Figure 2 and Figure 3The difference between this embodiment and the first embodiment is that: the elastic component 4 includes an elastic plate 41, the bottom of the elastic plate 41 is provided with two limiting grooves 42, the second limiting strip 34 is slidably connected in the limiting grooves 42, and the bottom of the elastic plate 41 is fixedly connected to the movable plate 31;

[0042] In this embodiment, the elastic plate 41 has good elastic deformation ability. When the support assembly 3 adjusts its shape, it can undergo elastic deformation along with the movement of the rotating plate 32, thereby playing a buffering and protective role, while ensuring that the top of the support frame fits tightly to the construction site.

[0043] Working principle and use process of the utility model: When the support frame is working, the top shape adjustment and support functions are realized based on the principle of thread transmission and the mechanical structure of hinged and sliding connection;

[0044] When the top shape needs to be adjusted, the operator rotates the turntable 23 to drive the threaded cylinder 21 to rotate, so that the threaded rod 22 moves up and down along the axial direction; the movement of the threaded rod 22 drives the movable plate 31 to rise and fall, and the movable plate 31 pushes the rotating plate 32 to rotate around the pin rod 35 through the pin rod 35; the first limit bar 33 at the bottom of the rotating plate 32 slides with the T-shaped through groove of the limit frame 13 to limit the movement direction of the rotating plate 32 and ensure its stable rotation; the second limit bar 34 at the top of the rotating plate 32 slides in the limit groove 42 of the elastic plate 41, and the elastic plate 41 undergoes elastic deformation; as the rotating plate 32 moves, the shape of the top of the support frame gradually changes until it fits the contour of the construction site;

[0045] During the support process, the soil or surrounding rock pressure at the construction site acts on the top of the support frame and is transmitted to the support component 1 through structures such as the rotating plate 32 and the movable plate 31. Finally, the support frame 11 and the connecting component 5 disperse the pressure to the ground to achieve stable support; the elastic component 4 plays a buffering and adaptive adjustment role to ensure that the support frame adapts to construction sites of different shapes and improves stability and reliability.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
