Description

Technical Field

[0001] The invention relates to the technical field of ditch support, and in particular to an ecological ditch support component based on a prefabricated safety guard plate. Background Art

[0002] During the construction of water conservancy projects, ditches need to be opened to guide the direction of the river. In order to prevent soil collapse and accidents during the excavation of the ditches, a protective net is usually laid inside the ditch to support the overall framework.

[0003] In the actual design process of the ditch, in order to reduce the pressure of water flow on the ditch side and extend the service life of the ditch, the ditch is usually set to a trapezoidal shape. The trapezoidal cross-section can convert the horizontal tension and impact force of the water flow into part of the downward force, reducing the damage to both sides of the ditch;

[0004] However, traditional ditch support components are difficult to adjust the support angle according to the inclination angle of the inclined surface inside the ditch, which may easily cause the protective net and the ditch to not fit tightly. At the same time, the depth and width of ditches in different areas are different during excavation. Most of the fixed protective nets, protective plates and other structures have fixed sizes, and the support status of protective nets, protective plates and other structures cannot be adjusted according to the specific conditions of the ditch.

[0012] Furthermore, one end of the spring 2 is fixedly connected to the movable column, and the other end is fixedly connected to the mounting groove, one end of the movable column passes through the outside of the mounting groove, and one end of the movable column is embedded and rollingly connected with a ball, and the outer surface of the support frame is annularly embedded and rollingly connected with several groups of steel balls at the position corresponding to the ball, and the steel balls are meshed with the ball.

[0013] Furthermore, the fixing assembly includes a threaded column and a limiting ring; the threaded column is fixedly connected to the corresponding support frame, the threaded column corresponding to the connecting plate passes through the threaded hole and the internal threaded ring and is threadedly connected thereto, the bottom end of the threaded column is conical, and a plurality of limiting rings are fixedly connected to the outer surface of the threaded column, the inner diameter of the limiting ring decreases from top to bottom, and the outer surface of the limiting ring is provided with threads.

During the movement of the limit bar, the teeth repeatedly mesh and correspond with the rack until one end of the limit bar conflicts with the side of the ditch. The rack limits the limit bar under the action of the spring 1, preventing the limit bar from entering the inside of the movable groove again under the action of soil and water during the support process of the protective net, thereby ensuring the stability of the support frame during the support process;

[0016] 2. In the present invention, when the support frame is pulled until the limit bar contacts the side of the ditch, the support frame is rotated until the side of the protective net is completely in contact with the side of the ditch, and the threaded column arranged on the side of the support frame is inserted into the interior of the ditch. The ball is meshed with the steel ball under the action of the second spring, thereby fixing the rotation angle of the support frame, preventing the support frame from rotating autonomously, and improving the stability of the ditch support;

[0017] In addition, when using protective nets to support ditches of different widths and inclination angles, the threaded columns on the connecting plates and the surfaces of the support pipes drive the limit rings whose inner diameters decrease from top to bottom to be inserted into the interior of the ditches, which can effectively increase the difficulty of the threaded columns separating from the ditches and improve the firmness of the ditch support.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Embodiment 1: Figure 1-3 As shown, the ecological ditch support assembly based on prefabricated safety guard plates proposed in the present invention includes two groups of bottom plates 1, a plurality of groups of connecting plates 3 are fixedly connected between the two groups of bottom plates 1, and limiting strips 2 are arranged at both ends of the two groups of bottom plates 1.

[0028] One end of the support frame 4 away from the guide rod is rotatably connected to a reeling rod 7, a protective net 8 is arranged between the two groups of reeling rods 7, and the two ends of the protective net 8 are respectively fixedly connected to the two groups of reeling rods 7, one end of the reeling rod 7 passes through the outside of the support frame 4 and is fixedly connected to a limiting block 12, and a torsion spring 11 is arranged on the outer surface of the reeling rod 7 between the limiting block 12 and the support frame 4, one end of the torsion spring 11 is fixedly connected to the limiting block 12, and the other end is fixedly connected to the support frame 4, pulling one group of support frames 4 to one side. In the process of the support frame 4 being pulled, the protective net 8 pulls the reeling rod 7 to rotate, so that ditches of different widths can be fully paved.

[0029] Embodiment 2: Figure 2-5 As shown, the difference between this embodiment and embodiment 1 is that an adjustment mechanism 5 for adapting to the width of the ditch is provided between the limit bar 2 and the bottom plate 1, and the adjustment mechanism 5 includes a movable groove 51, a slot hole 52, a guide column 53, a rack 54 and a spring 55;

[0030] Movable grooves 51 are provided at positions corresponding to the limit strips 2 at both ends of the base plate 1. When the support frame 4 is pulled, the limit strips 2 move along the movable grooves 51, and a slot hole 52 is provided on one side of the inner surface of the movable groove 51. Guide columns 53 are fixedly connected to the positions near the two ends of the slot holes 52. A rack 54 is movably connected between the two groups of guide columns 53, and a spring 55 is sleeved on the outer surface of the guide column 53. One end of the spring 55 is fixedly connected to the rack 54, and the other end is connected to the slot hole 52.

[0031] A tooth 56 is fixedly connected to one end of the outer surface of one side of the limit bar 2 away from the support frame 4, and the tooth 56 penetrates into the interior of the slot 52 and meshes with the rack 54. During the movement of the limit bar 2 along the movable slot 51, the tooth 56 repeatedly meshes and corresponds with the rack 54 until one end of the limit bar 2 conflicts with the side of the ditch. The rack 54 limits the limit bar 2 under the action of a spring 55 to prevent the limit bar 2 from entering the interior of the movable slot 51 again under the action of soil and water.

[0032] Embodiment 3: Figure 2-6 As shown, the difference between this embodiment and embodiment 1 and embodiment 2 is that one end of the limiting strip 2 is in conflict with the side of the ditch, and the support frame 4 is rotated outward, and a limiting mechanism 6 for controlling the rotation angle of the support frame 4 is provided between the support frame 4 and the limiting strip 2, and the limiting mechanism 6 includes a fixed column 61, a movable column 62 and a second spring 63;

[0033] A fixed column 61 is fixedly connected to one side of the outer surface of the limit strip 2 close to the support frame 4, and one end of the fixed column 61 is rotatably connected to a connecting shaft, which is fixedly connected to the support frame 4. A plurality of groups of mounting grooves are equidistantly arranged in a ring shape on the outer surface of the fixed column 61, and a movable column 62 and a spring 63 are arranged inside the mounting groove. The movable column 62 is movably connected to the mounting groove, and the support frame 4 drives the connecting shaft to rotate until the side of the protective net 8 is completely fitted with the side of the ditch.

[0034] One end of the spring 2 63 is fixedly connected to the movable column 62, and the other end is fixedly connected to the mounting groove. One end of the movable column 62 passes through the outside of the mounting groove, and one end of the movable column 62 is embedded and rollingly connected with a ball 64, and the outer surface of the support frame 4 corresponding to the ball 64 is annularly embedded and rollingly connected with a plurality of groups of steel balls 65, and the steel balls 65 are meshed with the balls 64. During the rotation of the support frame 4, the balls 64 repeatedly correspond and mesh with the steel balls 65 under the action of the spring 2 63, and finally the balls 64 are meshed with the steel balls 65, thereby fixing the rotation angle of the support frame 4, preventing the support frame 4 from rotating autonomously, and improving the stability and firmness of the ditch support.

[0035] Embodiment 4: Figure 1 , Figure 6 and Figure 7As shown, the difference between this embodiment and Embodiment 1, Embodiment 2 and Embodiment 3 is that a threaded hole is provided on the outer surface of the upper end of the connecting plate 3, and an internal threaded ring 10 is fixedly connected to the position of the outer surface of the protective net 8 corresponding to the threaded hole, and a fixing component 9 is provided between the internal threaded ring 10 and the threaded hole and on one side of the support frame 4.

[0036] The fixing assembly 9 includes a threaded column 91 and a limiting ring 92; the threaded column 91 is fixedly connected to the corresponding support frame 4, the threaded column 91 corresponding to the connecting plate 3 passes through the threaded hole and the internal threaded ring 10 and is threadedly connected thereto, the bottom end of the threaded column 91 is tapered, and the outer surface of the threaded column 91 is fixedly connected with a plurality of groups of limiting rings 92, the inner diameter of the limiting ring 92 decreases from top to bottom, and the outer surface of the limiting ring 92 is provided with threads;

[0037] The threaded column 91 set on the side of the support frame 4 is inserted into the interior of the ditch to ensure the stability of the support frame 4 during the support process. After the base plate 1 is located at the bottom of the ditch, the threaded column 91 on the surface of the connecting plate 3 is rotated clockwise to make it rotate into the soil. By setting a limit ring 92 with an inner diameter that decreases from top to bottom, the difficulty of the threaded column 91 being separated from the ditch can be effectively increased.

[0038] The working process and principle of the present invention are as follows:

[0039] Step 1: Place the device inside the ditch so that the bottom plate 1 is located at the bottom of the ditch, and then rotate the threaded column 91 on the surface of the connecting plate 3 clockwise to rotate it into the soil. By setting a limit ring 92 with an inner diameter that decreases from top to bottom, it can effectively increase the difficulty of the threaded column 91 to separate from the ditch;

[0040] Step 2: After adjusting the threaded column 91 on the surface of the connecting plate 3, pull a group of support frames 4 to one side, the limit bar 2 moves along the movable groove 51, and the teeth 56 repeatedly mesh and correspond with the rack 54 until one end of the limit bar 2 conflicts with the side of the ditch. The rack 54 limits the limit bar 2 under the action of the spring 55 to prevent the limit bar 2 from entering the inside of the movable groove 51 again under the action of soil and water, thereby ensuring the stability of the support frame 4 during the support process;

[0041] Step 3: When the support frame 4 is pulled, the protective net 8 pulls the reeling rod 7 to rotate, so that the bottom surface of ditches of different widths can be fully paved. When the support frame 4 is pulled until the limit bar 2 contacts the side of the ditch, the support frame 4 is rotated outward, and the support frame 4 drives the connecting shaft to rotate until the side of the protective net 8 is completely in contact with the side of the ditch. The threaded column 91 provided on the side of the support frame 4 is inserted into the interior of the ditch to ensure the stability of the support frame 4 during the support process. During the rotation of the support frame 4, the ball 64 repeatedly corresponds and meshes with the steel ball 65 under the action of the spring 2 63, and finally the ball 64 meshes with the steel ball 65, thereby fixing the rotation angle of the support frame 4, preventing the support frame 4 from rotating autonomously, and improving the stability and firmness of the ditch support.

[0042] Step 4: Adjust the status of another set of support frames 4 according to the above steps to complete the laying and support of the protection net 8 of the ditch.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
