Description

Technical Field

[0001] This utility model belongs to the field of water conservancy and hydropower construction technology, and in particular relates to a support device for water conservancy and hydropower construction. Background Technology

[0002] Water conservancy and hydropower construction refers to a series of engineering activities that utilize water resources, mainly including the surveying, planning, design, construction and management of water conservancy and hydropower projects.

[0003] During water conservancy and hydropower construction, multiple earthworks need to be excavated for deep work. However, the sides of the earthwork are stabilized by the balance between internal frictional resistance and cohesion. When this balance is lost, collapse can occur. Therefore, for safety reasons, support devices are installed on the earthwork to enhance the stability of the sides. However, existing support devices are composed of various connecting pipes and support plates, which makes on-site assembly quite troublesome, increasing labor and time costs for on-site construction and affecting the construction period. Furthermore, changing the support position later requires repeated disassembly and reassembly, which is inconvenient.

[0004] Therefore, how to provide a support device for water conservancy and hydropower construction is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model 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 merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The diagram shown is a structural schematic of a support device for water conservancy and hydropower construction according to an embodiment of the present invention, comprising:

[0028] Central Frame 1;

[0029] Support plates 8 are symmetrically arranged on both sides of the central frame 1. The upper inner side of the front support plate 8 is provided with an upper slide rail frame 7, and the lower inner side of the rear support plate 8 is provided with a lower slide rail frame 21.

[0030] The traction structure is located in the middle of the central frame 1 and is slidably hinged to the upper slide rail frame 7 and the lower slide rail frame 21 on the inner side of the support plate 8.

[0031] In this embodiment of the utility model, when in use, by setting a traction structure on the central frame 1, the movement of the traction structure can drive the support plate 8 away from or closer to the central frame 1, thereby adapting to earthwork slope support work of various widths, and realizing the rapid installation and support of the support plate 8, as well as convenient and quick disassembly and transportation.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown in the preferred embodiment of the present invention, the upper end of the support plate 8 is provided with an auxiliary protective structure. The auxiliary protective structure includes a storage groove 11 and a hinge block 14. The storage groove 11 is opened on the inner side of the upper end of the support plate 8. The surface of the storage groove 11 is arrayed with a second sliding groove 12. The hinge block 14 is slidably disposed inside the second sliding groove 12, and a protective plate 15 is fixedly installed on its outer end. The surface of the storage groove 11 is also provided with a traction unit, which is fixedly connected to the outer side of the lower end of the protective plate 15.

[0033] In this embodiment of the utility model, when in use, the protective plate 15 is pulled out from the storage groove 11 on the inner side of the upper end of the support plate 8, thereby driving the hinge block 14 to move in the second slide groove 12. When it moves to the limit position, it can be rotated to contact the ground.

[0034] By setting up an auxiliary protective structure, the protective plate 15 is used to protect the edge of the earthwork, thereby preventing people from stepping into the void due to the irregularity of the earthwork edge when looking inward. In addition, a traction unit is set up so that the protective plate 15 can apply pressure to the ground. With the cooperation of the support plate 8, the compactness of the soil on the side of the earthwork is increased, thereby improving its stability.

[0035] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, in a preferred embodiment of the present invention, the traction structure includes a traction rod 5 and a hinged slider 6. The surface of the central frame 1 is arrayed with rotating grooves 2, and a rotating block 3 is movably installed in the middle. A connecting rod 4 is provided between adjacent rotating blocks 3. The traction rod 5 is symmetrically arranged at both ends of the rotating block 3. The hinged slider 6 is fixedly installed on the outer end of the traction rod 5 and slidably arranged inside the upper slide rail frame 7 and the lower slide rail frame 21 on the front and rear sides. The bottom of the central frame 1 is provided with a first slide groove 9, and a multi-stage telescopic positioning plate 10 is slidably arranged inside, which is fixedly connected to the bottom of the lower end of the front and rear support plates 8.

[0036] In this embodiment of the utility model, when in use, the motor in the central frame 1 is started, which causes the rotating block 3 in the rotating groove 2 at the left end to rotate, and the rotating block 3 in the other rotating groove 2 is driven to rotate synchronously through the connecting rod 4, which in turn causes the traction rods 5 on both sides to move in opposite directions, thereby changing the position and angle of the hinged slider 6 in the upper slide rail frame 7 and the lower slide rail frame 21 at both ends.

[0037] With the cooperation of the multi-stage telescopic positioning plate 10 in the first sliding groove 9 at the bottom of the central frame 1, the traction rod 5 will push the support plate 8 away from the central frame 1 when it moves, thus adapting to earthwork slope support work of various widths.

[0038] like Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment of the present invention, the traction unit includes a movable groove 16, a lifting slider 18, and a tension spring 20. The movable groove 16 is symmetrically opened on the surface of the receiving groove 11, and a third sliding groove 17 is symmetrically opened at both ends. The lifting slider 18 is slidably disposed inside the third sliding groove 17, and a rotating positioning prism 19 is movably connected to its outer side. The tension spring 20 array is installed on the surface of the rotating positioning prism 19 and is fixedly connected to the outer side of the lower end of the protective plate 15.

[0039] In this embodiment of the utility model, when the protective plate 15 is pulled out, the tension spring 20 will pull the rotating positioning prism 19 to move upward, thereby driving the lifting slider 18 to move in the third sliding groove 17 on the side of the movable groove 16. Then, when the protective plate 15 changes angle, the tension spring 20 can drive the rotating positioning prism 19 to rotate.

[0040] By setting up a traction unit, a downward force can be applied to the protective plate 15 that is in contact with the ground, thereby preventing people from stepping into the void due to the irregularity of the earthwork edge when looking inwards. It can also apply pressure to the ground, thereby increasing the compactness of the soil on the side of the earthwork with the cooperation of the support plate 8, thus improving its stability.

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, the cross-sectional size of the storage groove 11 is equal to the cross-sectional size of the protective plate 15, and the width of the storage groove 11 is equal to the width of the protective plate 15.

[0042] In this embodiment of the utility model, when in use, the cross-sectional size of the storage groove 11 is equal to the cross-sectional size of the protective plate 15, and the width of the storage groove 11 is equal to the width of the protective plate 15, thereby facilitating the storage of the protective plate 15.

[0043] like Figure 4 and Figure 5 As shown, in a preferred embodiment of the present invention, a through groove 13 is provided between the two second sliding grooves 12 at both ends, and the two hinge blocks 14 at both ends are fixedly connected through the through groove 13.

[0044] In this embodiment of the utility model, when in use, a through groove 13 is provided between the two second sliding grooves 12, and the two hinge blocks 14 are fixedly connected through the through groove 13, so that the two hinge blocks 14 move up and down synchronously, and the two hinge blocks 14 are not easy to separate from the second sliding groove 12, thus affecting the use of the protective plate 15.

[0045] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, the front hinged slider 6 moves downward and the rear hinged slider 6 moves upward.

[0046] In this embodiment of the utility model, when in use, by moving the front hinged slider 6 downward and the rear hinged slider 6 upward, the support plate 8 can be moved away from the sides of the central frame 1, thereby facilitating the support of the earthwork edge.

[0047] The above embodiments of this utility model provide a support device for water conservancy and hydropower construction. When in use, the central frame 1 is moved into the earthwork pit, and then the motor in the central frame 1 is started, which causes the rotating block 3 in the rotating groove 2 at the left end to rotate, and drives the rotating blocks 3 in other rotating grooves 2 to rotate synchronously through the connecting rod 4.

[0048] When the rotating block 3 rotates, it will drive the traction rods 5 on both sides to move in opposite directions, thereby changing the position and angle of the hinged sliders 6 in the upper slide rail frame 7 and the lower slide rail frame 21 at both ends. With the cooperation of the multi-stage telescopic positioning plate 10 in the first slide groove 9 at the bottom of the central frame 1, when the traction rod 5 moves, it will push the support plate 8 away from the central frame 1, thus adapting to earthwork slope support work of various widths.

[0049] Furthermore, when rotated in the opposite direction, the support plate 8 will move closer to the central frame 1, thus completing the storage of the support plate 8. This enables the support plate 8 to be quickly installed and used for support, and also facilitates quick disassembly and transportation.

[0050] After the support work is completed, the protective plate 15 is pulled out from the storage groove 11 on the inner side of the upper end of the support plate 8, which in turn drives the hinge block 14 to move in the second slide groove 12. When it moves to the limit position, it can be rotated to make contact with the ground.

[0051] Meanwhile, when the protective plate 15 is pulled out, the tension spring 20 pulls the rotating positioning prism 19 upward, thereby driving the lifting slider 18 to move in the third sliding groove 17 on the side of the movable groove 16. Subsequently, when the protective plate 15 changes angle, the tension spring 20 drives the rotating positioning prism 19 to rotate, thereby applying a downward force to the protective plate 15 in contact with the ground. This prevents people from stepping into uneven soil edges when looking inward from the edge of the earthwork. It also applies pressure to the ground, thereby increasing the compactness of the soil on the side of the earthwork with the cooperation of the support plate 8, thus improving its stability.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
