[0025] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:
[0026] like Figure 1 As shown, this utility model provides a trench excavation support device for water conservancy projects, including a support plate 1 and a support plate 2. A transmission stud 3 is fixedly connected to the top of the support plate 2. The top of the transmission stud 3 extends through to the top of the support plate 1 and a rotating nut 4 is threaded on its outer surface. Two push rods 5 are movably connected to the front and rear ends of the support plate 1 and the support plate 2. A support column 6 is movably connected to the end of the two push rods 5 that are away from the support plate 1 and the support plate 2. A reinforcing rod 7 is provided on the upper and lower sides of the two support columns 6 that are close to the push rods 5. A support plate 8 is fixedly connected to the side of the two support columns 6 that are away from the support plate 1.
[0027] When the support device is in use, by rotating the nut 4 on the side of the transmission stud, the nut 4 can compress the support plate 1, causing the distance between the support plate 1 and the support plate 2 to gradually shorten. This allows the push rod 5 to push the support column 6, and the support plates 8 on both sides to unfold, thus supporting the trench. At the same time, by adjusting the rotation distance of the nut 4, the unfolding distance between the support plates 8 on both sides can be adjusted, which facilitates the support of trenches of different sizes. By inserting the reinforcing rod 7 into the side of the support column 6, the support columns 6 on both sides can be reinforced, making the support plate 8 more stable and preventing its collapse.
[0028] like Figure 2As shown, this utility model provides a trench excavation support device for water conservancy projects. The reinforcing rod 7 includes a connecting plate 71, which is disposed on the side of the support column 6 near the push rod 5. A knob 72 is movably connected to the side of the connecting plate 71 away from the support column 6. A movable groove is provided inside the connecting plate 71, and sliding grooves are provided at both the left and right ends of the connecting plate 71. The knob 72 near the support column 6 extends through the movable groove and is fixedly connected to a bevel gear 73. Bevel gears 74 are meshed on both the left and right sides of the outer surface of bevel gear 73. The bevel gears 74 are movably connected to the movable groove. On the left and right sides of the inner wall of the moving groove, the first screw 75 is fixedly connected to the side of the second bevel gear 74 away from the first bevel gear 73. The end of the first screw 75 away from the second bevel gear 74 passes through the interior of the first sliding groove and the outer surface is threadedly connected to the threaded slide plate 76. The threaded slide plate 76 is slidably connected to the interior of the first sliding groove. The end of the threaded slide plate 76 away from the first screw 75 is fixedly connected to the sliding pull plate 77. A tensioning plate 78 is provided on the side of the sliding pull plate 77 near the support column 6. The support column 6 is provided with locking grooves on both the upper and lower sides on the side near the push rod 5. The tensioning plate 78 extends into the interior of the locking groove.
[0029] When reinforcing the support column 6, the tensioning plate 78 is inserted into the locking groove. By rotating the knob 72, the bevel gear 73 and the bevel gear 74 are rotated, which in turn causes the first screw 75 to rotate. This causes the threaded slide plate to slide inside the sliding groove, thereby tightening the sliding plate 77 and locking the tensioning plate 78 inside the locking groove, thus reinforcing the support column 6.
[0030] like Figure 3 As shown, this utility model provides a trench excavation support device for water conservancy projects. A sliding groove 2 is provided on the side of the sliding pull plate 77 near the support column 6. Sliding groove 3 is provided on both the upper and lower sides of the side of the sliding pull plate 77 away from the threaded slide plate 76. The tensioning plate 78 includes a right-angle clamping plate 781, which is slidably connected to the inside of the sliding groove 2 and extends into the inside of the clamping groove. Guide columns 782 are fixedly connected on both the upper and lower sides of the side of the right-angle clamping plate 781 away from the threaded slide plate 76. The end of the guide column 782 away from the right-angle clamping plate 781 passes through the inside of the sliding groove 3 and is fixedly connected to a top spring 783. A right-angle pressure plate 784 is slidably connected on the side of the right-angle clamping plate 781 near the threaded slide plate 76. A push plate 785 is movably connected on the side of the right-angle pressure plate 784 near the guide column 782. The end of the push plate 785 away from the right-angle pressure plate 784 is movably connected to the inner wall of the sliding groove 2.
[0031] When the inside of the snap-fit groove is clamped by the tensioning plate 78, the right-angle plate 781 will press against the inside of the snap-fit groove. At the same time, the right-angle plate 781 will slide inside the sliding groove 2. It can still press against the tensioning spring 783 through the guide post 782. Thus, the right-angle pressure plate 784 can be pushed by the push plate 785 to press against the inside of the snap-fit groove, so that the reinforcement effect of the support post 6 is better.
[0032] like Figure 4 As shown, this utility model provides a trench excavation support device for water conservancy projects. The support plate 8 includes a vertical plate 81, which is fixedly connected to the side of two support columns 6 arranged in front and behind, away from the support plate 1. A rotating plate 82 is movably connected to the bottom end of the vertical plate 81 away from the support column 6. A sliding groove 4 is opened on the side of the vertical plate 81 away from the support column 6. A knob 2 83 is movably connected to the top end of the vertical plate 81. A second screw 84 is fixedly connected to the bottom end of the knob 2 83. The bottom end of the second screw 84 penetrates into the interior of the sliding groove 4 and a threaded slider 85 is threadedly connected to its outer surface. A top rod 86 is movably connected to both the front and rear sides of the threaded slider 85. The end of the top rod 86 away from the threaded slider 85 is movably connected to the side of the rotating plate 82 close to the vertical plate 81.
[0033] When the support plate 8 is in use, rotating the knob 83 will drive the second screw 84 to rotate, and drive the threaded slider 85 to slide inside the sliding groove 4. This will cause the top rod 86 to push the rotating plate 82 to rotate around the bottom of the vertical plate 81, thereby adjusting the angle of the rotating plate 82 and the support angle of the support plate 8, which facilitates the support of water conservancy engineering trenches at different angles.
[0034] like Figure 5 As shown, this utility model provides a trench excavation support device for water conservancy projects. The bottom front and rear sides of the rotating plate 82 are fixedly connected with connecting columns 821. The middle of the connecting column 821 is provided with a connecting slot 822 that runs through the front and rear. The lower front and rear sides of the vertical plate 81 are fixedly connected with connecting inserts 811. The connecting inserts 811 are slidably inserted into the inside of the connecting slot 822. By inserting the connecting inserts 811 into the inside of the connecting slot 822, the rotating plate 82 and the vertical plate 81 can be connected. The rotation of the connecting column 821 on the side of the connecting insert 811 can facilitate the rotation of the rotating plate 82.
[0035] The working principle of the trench excavation and support device used in this water conservancy project will be explained in detail below.
[0036] like Figure 1-5As shown, when the support device is in use, rotating the nut 4 on the side of the transmission stud gradually shortens the distance between support plate 1 and support plate 2, thereby pushing the support column 6 through the push rod 5 and unfolding the support plates 8 on both sides to support the trench. At the same time, the knob 2 83 drives the second screw 84 to rotate, which in turn drives the threaded slider 85 to drive the push rod 86 to rotate the rotating plate 82, thereby adjusting the angle of the rotating plate 82 so that the rotating plate is in close contact with the trench and can support the trench. Then, the tensioning plate 78 is inserted into the locking groove, and the tensioning plate 78 is tightened by rotating the knob 1 72, which can reinforce the support columns 6 on both sides, making the use of the support plate 8 more stable and improving the support effect.
[0037] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
