Description

Technical Field

[0001] The utility model relates to the technical field of slope retaining wall support, and more specifically, to a slope retaining wall support structure. Background Art

[0002] In water conservancy projects, it is often necessary to use slope retaining wall support structures to protect the slopes to prevent soil sliding, landslides, etc., so as to facilitate construction by workers. The height of existing slope retaining wall support structures is usually fixed. When the retaining height is not enough, the installed retaining wall needs to be removed and then a higher retaining wall needs to be installed. The operation is very cumbersome, which wastes time and increases the labor intensity of the workers, making the entire retaining wall support structure less flexible. Secondly, the retaining wall structure in the existing slope retaining wall support structure is relatively simple. When facing a high slope, the high slope terrain has a relatively greater pressure on the retaining wall. A single retaining wall structure cannot guarantee the stability of the slope structure when facing a high slope. Utility Model Content

[0030] Two support arms 12 are fixedly provided on one side of the upper retaining wall 5 , and a sleeve 13 is fixedly provided on the lower end of each support arm 12 .

[0031] In this embodiment, a plurality of mounting holes are provided on the base 1, and the base 1 can be fixed to the position where it needs to be installed through the mounting holes. When the height of the lower retaining wall 2 is not enough, the upper retaining wall 5 is moved so that the upper retaining wall 5 drives the mounting plate 4 to be inserted into the mounting chamber 3, and the mounting plate 4 drives the two plug-in plates 6 to be inserted into the two slots 7, and the bidirectional lead screw 9 rotates. The bidirectional lead screw 9 is provided with two threaded areas in opposite directions, so that the two fixing plates 10 move in opposite directions along the driving shell 8, and the fixing plate 10 drives the fixing rod 11 to move, so that the fixing rod 11 is inserted into the plug-in plate 6 to fix the plug-in plate 6, and the plug-in plate 6 drives the mounting plate 4 and the upper retaining wall 5 to be fixed to the lower retaining wall 2.

[0032] More specifically, when the height of the lower retaining wall 2 is not enough, the upper retaining wall 5 can be installed on the lower retaining wall 2, and the fixing rod 11 fixes the plug plate 6 through the rotation of the bidirectional screw 9, thereby fixing the upper retaining wall 5. The sleeve 13 can support the support arm 12, and the support arm 12 supports the upper retaining wall 5.

[0033] See also Figure 1-5 As an implementation method for rotating the bidirectional lead screw 9: a driven bevel gear 14 is fixedly provided on the bidirectional lead screw 9, a turning handle 15 is rotatably provided on one side of the drive housing 8, one end of the turning handle 15 extends into the drive housing 8 and is fixedly connected to a driving bevel gear 16.

[0034] Specifically, the handle 15 is turned, and the handle 15 drives the driving bevel gear 16 to rotate. Since the driven bevel gear 14 and the driving bevel gear 16 are meshed and connected, the driving bevel gear 16 drives the driven bevel gear 14 to rotate, and the driven bevel gear 14 drives the bidirectional screw 9 to rotate.

[0035] See also Figure 1-5 As an implementation method for supporting the upper retaining wall 5: two reinforcing plates 17 are fixedly provided on one side of the lower retaining wall 2, and the lower end of each reinforcing plate 17 is fixedly connected to the base 1, a screw 18 is movably provided in the sleeve 13, and the lower end of the screw 18 passes through the sleeve 13 and is fixedly connected to a support seat 19, a rotating ring 20 is rotatably provided on the sleeve 13, and the rotating ring 20 is threadedly connected to the screw 18, and two limit blocks 21 are fixedly provided on the screw 18 extending into the sleeve 13, and two limit grooves 22 matching the limit blocks 21 are provided on the sleeve 13.

[0036] Specifically, the two reinforcing plates 17 support the lower retaining wall 2 and the base 1 to increase the stability of the lower retaining wall 2. The rotating ring 20 is rotated, and the rotating ring 20 rotates around the rotating connection with the sleeve 13. Since the sleeve 13 is threadedly connected to the screw 18, the screw 18 moves downward, and the screw 18 drives the limit block 21 to move along the limit groove 22 to limit it. At the same time, the screw 18 drives the support seat 19 to move downward, so that the support seat 19 contacts the base 1, thereby supporting the upper retaining wall 5 and increasing its stability.

[0037] See also Figure 1-5 As an implementation method for fixing the turning handle 15: a gear ring 23 is fixedly provided on the turning handle 15, a support plate 24 is fixedly provided on one side of the driving shell 8, a bolt 25 is threadedly connected to the support plate 24, one end of the bolt 25 passes through the support plate 24 and is rotatably connected to a block 26 that matches the gear ring 23 through a bearing, and one side of the block 26 is slidably connected to the driving shell 8 through a track structure.

[0038] Specifically, when the handle 15 rotates, the handle 15 drives the gear ring 23 to rotate. When the handle 15 is used, the bolt 25 is rotated. Since the bolt 25 is threadedly connected to the support plate 24, the bolt 25 rotates and moves in the direction of the gear ring 23. The bolt 25 drives the clamping block 26 to move along the sliding connection with the drive housing 8, thereby clamping the gear ring 23 out, and the handle 15 can be fixed.

[0039] In summary, when the overall equipment is in use:

[0040] When the retaining height of the lower retaining wall 2 is not enough, the base 1 is provided with a plurality of mounting holes, and the base 1 can be fixed to the position where the installation is required through the mounting holes. When the height of the lower retaining wall 2 is not enough, the upper retaining wall 5 is moved so that the upper retaining wall 5 drives the mounting plate 4 to be inserted into the mounting chamber 3, and the mounting plate 4 drives the two plugging plates 6 to be inserted into the two slots 7, and the turning handle 15 is turned. The turning handle 15 drives the driving bevel gear 16 to rotate. Since the driven bevel gear 14 and the driving bevel gear 16 are meshed and connected, the driving bevel gear 16 will drive the driven bevel gear 14 to rotate, and the driven bevel gear 14 drives the bidirectional lead screw 9 to rotate. The bidirectional lead screw 9 is provided with two threaded areas in opposite directions, so that the two fixing plates 10 move in opposite directions along the driving shell 8, and the fixing plate 10 drives the fixing rod 11 to move, so that the fixing rod 11 is inserted into the plugging plate 6 to fix the plugging plate 6, and the plugging plate 6 drives the mounting plate 4 and the upper retaining wall 5 to be fixed to the lower retaining wall 2.

[0041] When the stability of the lower retaining wall 2 and the upper retaining wall 5 needs to be strengthened, the two reinforcing plates 17 support the lower retaining wall 2 and the base 1 to increase the stability of the lower retaining wall 2. The rotating ring 20 is rotated, and the rotating ring 20 rotates around the rotating connection with the sleeve 13. Since the sleeve 13 is threadedly connected to the screw 18, the screw 18 moves downward, and the screw 18 drives the limit block 21 to move along the limit groove 22 to limit it. At the same time, the screw 18 drives the support seat 19 to move downward, so that the support seat 19 contacts the base 1, thereby supporting the upper retaining wall 5 and increasing its stability.

[0042] When the handlebar 15 needs to be fixed, the handlebar 15 rotates, driving the gear ring 23 to rotate. After the handlebar 15 is used, the bolt 25 is turned. Since the bolt 25 is threadedly connected to the support plate 24, the bolt 25 rotates and moves toward the gear ring 23. The bolt 25 drives the clamping block 26 to move along the sliding connection with the drive housing 8, thereby clamping the gear ring 23 out and fixing the handlebar 15.

[0043] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model.
