Description

Technical Field

[0001] This utility model relates to the field of support device technology, and in particular to a support device for excavating high slopes of dams. Background Technology

[0002] In the construction of water conservancy projects, the excavation and support of high slopes of dams is a crucial link. With the continuous expansion of the scale and increasing complexity of water conservancy projects, the requirements for high slope support devices are also increasing. Especially in areas with complex geological conditions and varied terrain, the stability and safety of high slopes are directly related to the safety and stability of the entire water conservancy project.

[0003] A Chinese patent discloses a support device for excavating high slopes of dams (authorization announcement number CN213233316U). This patented technology facilitates the fixed connection between the net body and the column, saving connection time, improving work efficiency, reducing the workload of workers, and the net body can be rolled up through the connecting rod, making it convenient to transport and move.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: In actual engineering, the excavation width of high slopes often varies due to various factors such as geological conditions, construction technology, and design changes. However, existing support structures lack an effective width adjustment mechanism and are difficult to adapt to such changes, resulting in a significant reduction in support effectiveness. When the excavation width is greater than the preset width of the support structure, the support structure may not be able to provide sufficient support force, threatening the stability of the slope. When the excavation width is less than the width of the support structure, it will result in a waste of support materials and increase construction costs. Utility Model Content

[0005] The technical problem to be solved by this utility model is that existing technologies have fixed-size baffles, rigid support frames, etc., which have the disadvantage that once designed and installed, the support width is difficult to adjust flexibly according to actual construction needs. Therefore, we propose a support device for high slope excavation of dams.

[0006] To achieve the above objectives, this application adopts the following technical solution: a support device for excavating high slopes of dams, comprising an adjusting plate, with support plates at both ends of the adjusting plate, and four adjusting plates in total. Adjusting grooves are formed on both sides of the adjusting plate, and support plates are slidably connected inside the adjusting grooves. A limit block is fixedly connected to the side of the support plate near the adjusting plate, and a support block is fixedly connected to the side of the support plate near the limit block. Adjusting boxes are fixedly connected to both sides of one end of the adjusting plate, with control grooves formed at both ends of the adjusting boxes. Adjusting blocks are slidably connected inside the control grooves, and a through groove is formed at the top of the control groove. An insert block is fixedly connected to the top of the adjusting block. A straight groove is formed on the side of the support plate near the adjusting box, and several slots are formed at both ends of the straight groove.

[0007] Preferably, a storage spring is fixedly connected to the side of the adjusting block near the inside of the control slot, and the side of the storage spring away from the adjusting block is fixedly connected to the inside of the control slot.

[0008] Preferably, guide grooves are provided on both sides of the control groove, and guide blocks are fixedly connected to both sides of the adjustment block, with the surface of the guide block slidingly connected to the interior of the guide groove.

[0009] Preferably, the size of the insert is adapted to the size of the slot, and the surface of the insert is inserted into the interior of the slot.

[0010] Preferably, both ends of the adjustment groove are provided with sliding grooves, and both ends of the support plate are fixedly connected with sliders, the surface of the sliders being slidably connected to the inside of the sliding grooves.

[0011] Preferably, a return spring is fixedly connected to the side of the adjustment groove near the support plate, and a push block is fixedly connected to the side of the return spring near the support plate.

[0012] Preferably, a screw is provided inside the support block, and a nut is provided on the side of the limiting block away from the screw.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] In this invention, the worker pushes the adjusting block into the control slot, causing the adjusting block to move the insert block and release the limiting position between the insert block and the slot. The worker then moves the support plate outward from the adjusting slot, causing the support plate to move the support block to abut against the limiting block and the support plate. This arrangement allows the worker to support the support structure, and the length of the support can be adjusted according to the terrain features. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a support device for excavating high slopes of dams, including an adjusting plate 1, with support plates 2 at both ends of the adjusting plate 1, and four adjusting plates 1 in total. Adjusting grooves 3 are provided on both sides of the adjusting plate 1, and support plates 4 are slidably connected inside the adjusting grooves 3. A limiting block 5 is fixedly connected to the side of the support plate 2 near the adjusting plate 1, and a support block 6 is fixedly connected to the side of the support plate 4 near the limiting block 5. Adjusting boxes 7 are fixedly connected to both sides of one end of the adjusting plate 1, and control grooves 8 are provided at both ends of the adjusting boxes 7. Adjusting blocks 9 are slidably connected inside the control grooves 8, and a through-hole is provided at the top of the control groove 8. The top of the adjusting block 9 is fixedly connected to the slot 10. The support plate 4 has a straight slot 12 on the side near the adjusting box 7. Both ends of the straight slot 12 have several slots 13. The operator pushes the adjusting block 9 into the control slot 8, so that the adjusting block 9 drives the insert block 11 to move and releases the limit between the insert block 11 and the slot 13. The operator moves the support plate 4 to the outside of the adjusting slot 3, so that the support plate 4 drives the support block 6 to abut against the limit block 5 and the support plate 2. The above settings allow the operator to support the support structure and adjust the length of the support according to the terrain features.

[0022] Reference Figure 4As shown in this embodiment: A storage spring 14 is fixedly connected to the side of the adjusting block 9 near the inside of the control groove 8, and the side of the storage spring 14 away from the adjusting block 9 is fixedly connected to the inside of the control groove 8. When the operator pushes the adjusting block 9 into the inside of the control groove 8, the adjusting block 9 compresses the storage spring 14 to store force, and drives the insert 11 to release the limit between it and the slot 13. After the operator adjusts the applicable position of the support plate 4, the insert 11 is aligned with the slot 13 and the adjusting block 9 is released. Under the action of the rebound force of the storage spring 14, the insert 11 quickly snaps into the inside of the slot 13, and the support plate 4 is limited and fixed.

[0023] Reference Figure 4 As shown in this embodiment: guide grooves 15 are provided on both sides of the control groove 8, and guide blocks 16 are fixedly connected to both sides of the adjusting block 9. The surface of the guide block 16 is slidably connected to the inside of the guide groove 15. When the operator moves the adjusting block 9, the adjusting block 9 drives the guide block 16 to slide inside the guide groove 15. Through the above settings, the adjusting block 9 is more stable during movement, avoiding shaking and improving the operating accuracy of the equipment. At the same time, the sliding connection design between the guide block 16 and the guide groove 15 reduces friction and extends the service life of the equipment. In addition, this structure also makes it easier for the operator to quickly adjust the adjusting block 9, improving work efficiency.

[0024] Reference Figure 3 As shown, in this embodiment, the size of the insert 11 is adapted to the size of the slot 13, and the surface of the insert 11 is inserted into the interior of the slot 13. By adapting the size of the insert 11 to the size of the slot 13, the insert 11 can be stably inserted into the slot 13, thereby achieving a firm connection between the support plate 4 and the adjustment box 7, enhancing the stability and reliability of the overall structure. This insertion method is not only simple and easy to implement, but also effectively prevents the support plate 4 from shaking or falling off during use, further improving the performance and safety of the equipment.

[0025] Reference Figure 3 As shown in this embodiment: both ends of the adjusting groove 3 are provided with sliding grooves 17, and both ends of the support plate 4 are fixedly connected with sliders 18. The surface of the slider 18 is slidably connected to the inside of the sliding groove 17. When the operator moves the support plate 4, the slider 18 drives the sliding groove 17 to move. Through the above settings, the support plate 4 is more stable during movement, avoiding shaking or deviation, and improving the stability and reliability of the overall structure. At the same time, the sliding connection design between the slider 18 and the sliding groove 17 also makes the movement of the support plate 4 smoother and reduces friction and resistance.

[0026] Reference Figure 3As shown in this embodiment: a return spring 19 is fixedly connected to the side of the adjustment groove 3 near the support plate 4, and a push block 20 is fixedly connected to the side of the return spring 19 near the support plate 4. With the arrangement of the return spring 19 and the push block 20, when the support plate 4 moves to the bottom of the adjustment groove 3, the support plate 4 pushes the push block 20 to compress and store force on the return spring 19. Through the above arrangement, a buffering effect is effectively achieved, reducing the impact of the support plate 4 on the overall structure during the movement, and further protecting the stability and service life of the equipment.

[0027] Reference Figure 3 As shown in this embodiment: a screw 21 is provided inside the support block 6, and a nut 22 is provided on the side of the limiting block 5 away from the screw 21. Through the arrangement between the screw 21 and the nut 22, the workers can fix the support block 6 inside the limiting block 5 to ensure the stability of the support, and at the same time facilitate the disassembly of the support block 6, so that the workers can disassemble the whole and facilitate the workers to transport it later.

[0028] Working principle: The operator pushes the adjusting block 9 into the control slot 8, causing the adjusting block 9 to move the insert block 11, releasing the insert block 11 from its limiting position in the slot 13. The operator moves the support plate 4 outwards from the adjusting slot 3, causing the support plate 4 to move the support block 6 to abut against the limiting block 5 and the support plate 2. This setup allows the operator to support the support structure, and the length of the support can be adjusted according to the terrain features. When the operator pushes the adjusting block 9 into the control slot 8, the adjusting block 9 compresses the storage spring 14, storing energy and causing the insert block 11 to release its limiting position in the slot 13. After the operator adjusts the support plate 4 to the appropriate position... Align the insert 11 with the slot 13 and release the adjusting block 9. Under the rebound force of the storage spring 14, the insert 11 quickly snaps into the slot 13, limiting and fixing the support plate 4. When the operator moves the adjusting block 9, the adjusting block 9 drives the guide block 16 to slide inside the guide groove 15. Through the above settings, the adjusting block 9 is more stable during movement, avoiding shaking and improving the operating accuracy of the equipment. At the same time, the sliding connection design between the guide block 16 and the guide groove 15 reduces friction and extends the service life of the equipment. In addition, this structure also facilitates the operator to quickly adjust the adjusting block 9, improving work efficiency. The size-matched design of the 13 allows the insert 11 to be stably inserted into the slot 13, thus achieving a secure connection between the support plate 4 and the adjustment box 7. This enhances the stability and reliability of the overall structure. This insertion method is not only simple and easy to implement, but also effectively prevents the support plate 4 from shaking or falling off during use, further improving the performance and safety of the equipment. When the operator moves the support plate 4, the slider 18 drives the slide groove 17 to move. Through the above-mentioned design, the support plate 4 is more stable during movement, avoiding shaking or displacement, and improving the stability and reliability of the overall structure. At the same time, the sliding connection design between the slider 18 and the slide groove 17 also... This design allows for smoother movement of the support plate 4, reducing friction and resistance. Through the arrangement of the return spring 19 and the push block 20, when the support plate 4 moves to the bottom of the adjusting groove 3, it pushes the push block 20 to compress and store force on the return spring 19. This effectively buffers the impact of the support plate 4 on the overall structure during movement, further protecting the stability and service life of the equipment. The screw 21 and nut 22 allow workers to fix the support block 6 inside the limiting block 5, ensuring the stability of the support and facilitating disassembly of the support block 6. This allows workers to disassemble the entire structure for convenient subsequent transportation.
