[0034] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0035] As Figures 1-9 shown, a formwork support device for an inclined tall and thin-walled reinforced concrete wall with large cavities according to the present invention includes a chassis 1. A plurality of mounting blocks 2 are symmetrically and fixedly installed on both sides of the chassis 1. A first movable shaft 3 is fixedly installed on the chassis 1. A support plate 4 is movably installed on the first movable shaft 3. Two shaft blocks 5 are fixedly installed on the back surface of the support plate 4. A shaft rod 6 is jointly movably installed inside the two shaft blocks 5. Two movable plates 7 are fixedly installed on the shaft rod 6. A bottom sleeve 8 is movably sleeved outside the movable plate 7. A support plate 9 is fixedly installed at the bottom of the bottom sleeve 8. A touch frame 48 is jointly fixedly installed on the two bottom sleeves 8. A connecting bar 10 is jointly fixedly installed between the two movable plates 7. A tooth rack 11 is fixedly installed at the bottom of the connecting bar 10. The two bottom sleeves 8 jointly fixedly install a fixing plate 12. A driving motor 13 is fixedly installed on the fixing plate 12. The output end of the driving motor 13 passes through the inside of the fixing plate 12 through a bearing. A gear 14 is fixedly installed at the bottom of the output end of the driving motor 13.

[0036] Specifically, the chassis 1 is carried to one side of the formwork of the reinforced concrete wall that needs to be supported. The mounting blocks 2 are fixedly installed by bolts to fix the chassis 1. The support plate 4 is vertically rotated so that the support plate 4 rotates around the first movable shaft 3 under the action of an external force. When it rotates to the specified state, hold the two bottom sleeves 8 and rotate the movable plate 7 through the bottom sleeve 8 so that the movable plate 7 drives the shaft rod 6 to rotate around the shaft rod 6 under the action of an external force. The support plate 9 is moved to the specified position through the bottom sleeve 8. By controlling the driving motor 13 to operate, the rotation of the output end of the driving motor 13 can drive the gear 14 to rotate. The gear 14 drives the tooth rack 11 to move through meshing, so that the tooth rack 11 drives the movable plate 7 to move out of the inside of the bottom sleeve 8 under the action of an external force through the connecting bar 10. The movable plate 7 drives the support plate 4 to rotate around the first movable shaft 3 through the shaft rod 6 and the shaft block 5, so that the support plate 4 tightly abuts against the formwork of the reinforced concrete wall. By adjusting the inclination angle of the support plate 4, formworks of various types of inclined tall and thin-walled reinforced concrete walls with large cavities can be supported.

[0037] In this embodiment, saw teeth racks 15 are symmetrically and fixedly installed on both sides of the tooth rack 11. A bottom block 16 is fixedly installed on one side of the bottom sleeve 8. A central block 17 and a side shell 18 are fixedly installed on the bottom block 16, and the side shell 18 is located outside the central block 17. A clamping block 19 is movably installed between the central block 17 and the side shell 18, and the clamping block 19 is clamped with the tooth gaps of the saw teeth racks 15. A first torsion spring 20 is connected to the bottom block 16, and the first torsion spring 20 is located between the central block 17 and the side shell 18. The end of the first torsion spring 20 is connected to the clamping block 19.

[0038] Specifically, the side shell 18 can limit the clamping block 19 to move in only one direction under the action of an external force. When the tooth rack 11 moves, the tooth rack 11 can drive the saw teeth racks 15 to move under the action of an external force, so that the saw teeth racks 15 can drive the clamping block 19 to move around the central block 17 through the tooth gaps. After the movement of the saw teeth racks 15 stops, the first torsion spring 20 uses its own elastic force to support the clamping block 19 to be clamped with the tooth gaps of the corresponding saw teeth racks 15, thereby preventing loosening caused by adjustment and increasing the firmness of adjustment.

[0039] In this embodiment, the support mechanism includes a support frame 21 fixedly installed on the top of the bottom frame 1. The top end of the support frame 21 is fixedly installed with a circular plate 22. An outer cover 33 is fixedly installed on the front of the circular plate 22. An activity opening and a circular hole are penetratingly opened on the outer cover 33;

[0040] The knocking mechanism includes a semi-circular sleeve 23 fixedly installed on the front of the circular plate 22. An activity opening and a socket are penetratingly opened on the semi-circular sleeve 23. A bending spring 24 is connected to the inner side of the semi-circular sleeve 23. A spherical body 25 is fixed to the end of the bending spring 24. The spherical body 25 is located inside the semi-circular sleeve 23. A pull rod 26 is fixedly installed on one side of the spherical body 25, and the pull rod 26 movably penetrates through the inner side of the activity opening of the semi-circular sleeve 23. A steel sheet 32 is fixedly installed on the front of the circular plate 22, and the steel sheet 32 is located on one side of the semi-circular sleeve 23. An alarm 34 is fixedly installed on the back of the circular plate 22;

[0041] The triggering mechanism is fixed on the circular plate 22 and is located inside the outer cover 33, and is used to fix the spherical body 25 and trigger the movement of the spherical body 25. The triggering mechanism includes a tension spring 27 connected to the circular plate 22. A trigger block 28 is fixedly installed at the end of the tension spring 27, and the trigger block 28 is located inside the circular hole of the outer cover 33. A short rod 29 is fixedly installed on the back of the trigger block 28. A short plate 30 is fixedly installed on one side of the short rod 29. A blocking block 31 is fixedly installed on one side of the short plate 30, and the blocking block 31 is located inside the socket of the semi-circular sleeve 23 and abuts against the spherical body 25. A support 35 is fixedly installed on one side of the support frame 21. A threaded block 36 is movably installed through the inside of the support 35. A rotating rod 37 is fixedly installed on one side of the threaded block 36, and the top of the rotating rod 37 is located on one side of the trigger block 28. A fastening nut 38 is threadedly installed on the outside of the threaded block 36.

[0042] Specifically, when the support plate 4 and the bottom sleeve 8 become loose due to support, the bottom sleeve 8 will drive the trigger frame 48 to move, so that the trigger frame 48 drives the rotating rod 37 to move, so that the rotating rod 37 drives the fastening nut 38 to become loose under the action of an external force. The rotating rod 37 rotates around the threaded block 36, so that the top of the rotating rod 37 can squeeze the trigger block 28, so that the trigger block 28 drives the blocking block 31 to move through the short rod 29 and the short plate 30 under the action of an external force, so that the blocking block 31 can move out of the inside of the semi-circular sleeve 23 through the socket of the semi-circular sleeve 23, so that the blocking block 31 no longer blocks the spherical body 25, so that the bending spring 24 can drive the spherical body 25 to move along the inside of the semi-circular sleeve 23 by its own elastic force, so that the spherical body 25 can impact the steel sheet 32, and generate a sound inside the outer cover 33 through the impact on the steel sheet 32, so as to give a warning. At the same time, due to the impact, vibration is generated on the circular plate 22, so as to trigger the alarm 34 on the circular plate 22 to give an alarm, and further give a warning to the relevant staff, so that the staff can carry out maintenance work immediately through the warning;

[0043] After the maintenance work is completed, the rotating rod 37 is separated from the trigger block 28, so that the tension spring 27 can drive the trigger block 28 to reset by its own elastic force. The trigger block 28 drives the blocking block 31 to move back into the inside of the semi-circular sleeve 23 through the short rod 29 and the short plate 30. The staff manually presses the trigger block 28 to move the blocking block 31 out of the inside of the semi-circular sleeve 23, and pulls the pull rod 26, so that the pull rod 26 can drive the spherical body 25 to carry out the reset work under the action of an external force, and then releases the trigger block 28, so that the blocking block 31 moves into the inside of the semi-circular sleeve 23 to contact the spherical body 25 to fix the spherical body 25.

[0044] In this embodiment, a stress-bearing frame 39 is fixedly installed on the support frame 21. A housing 40 is fixedly installed on one side of the stress-bearing frame 39. An opening is formed through the top end of the housing 40. A conical spring 41 is connected to the inner wall of the top end of the housing 40. The bottom of the conical spring 41 is connected to a frame plate 42, and the frame plate 42 is located inside the housing 40. A shovel block 43 is fixedly installed at the bottom of the frame plate 42. A second movable shaft 44 is fixedly installed at the top of the frame plate 42, and the second movable shaft 44 is located on one side of the conical spring 41. A latch 46 is movably installed on the second movable shaft 44 through two second torsion springs 45, and the latch 46 is located inside the opening of the housing 40. A trigger block 47 is fixedly installed at the top end of the latch 46, and the trigger block 47 is located on one side of the rotating rod 37.

[0045] Specifically, when the rotating rod 37 rotates, the bottom end of the rotating rod 37 drives the trigger block 47 to move, so that the trigger block 47 drives the latch 46 to move under the action of an external force, so that the latch 46 rotates around the second movable shaft 44 under the elastic support of the second torsion spring 45, so that the latch 46 is no longer clamped with the housing 40, so that the conical spring 41 uses its own elastic force to push the frame plate 42 downward, so that the frame plate 42 drives the shovel plate to move downward. At the same time, the second torsion spring 45 uses its own elastic force to drive the latch 46 to rotate back to its original position, so that the shovel block 43 contacts the ground. When the support plate 4 supporting the reinforced concrete wall formwork becomes loose, the shovel block 43 supports the support plate 4 by shoveling into the ground, thereby increasing the stability of the support of the support plate 4;

[0046] After the staff performs maintenance, the trigger block 47 is used to pull the latch 46 upward, so that the latch 46 drives the shovel block 43 to return to its original position through the second movable shaft 44 and the frame plate 42. The latch 46 is rotated so that the latch 46 is clamped with the housing 40 again to fix the shovel block 43 for the next trigger operation at any time.

[0047] Working principle: Move the chassis 1 to one side of the reinforced concrete wall formwork that needs to be supported. Fix the mounting block 2 through bolts. Vertically rotate the support plate 4 so that the support plate 4 rotates around the first movable shaft 3 under the action of an external force. When it rotates to the specified state, hold two bottom sleeves 8 and rotate the movable plate 7 through the bottom sleeves 8, so that the movable plate 7 drives the shaft rod 6 to rotate around the shaft rod 6 under the action of an external force. Move the support plate 9 to the specified position through the bottom sleeves 8. Control the driving motor 13 to operate, so that the rotation of the output end of the driving motor 13 can drive the gear 14 to rotate. The gear 14 drives the tooth rack 11 to move through meshing, so that the tooth rack 11 drives the movable plate 7 to move out of the inner side of the bottom sleeve 8 under the action of an external force through the connecting bar 10. When the tooth rack 11 moves, the tooth rack 11 can drive the saw tooth rack 15 to move under the action of an external force, so that the saw tooth rack 15 can drive the clamping block 19 to move around the center block 17 through the tooth gaps. When the movement of the saw tooth rack 15 stops, the first torsion spring 20 uses its own elastic force to support the clamping block 19 to be clamped in the tooth gaps of the corresponding saw tooth rack 15. The movable plate 7 drives the support plate 4 to rotate around the first movable shaft 3 through the shaft rod 6 and the shaft block 5, so that the support plate 4 tightly abuts against the reinforced concrete wall formwork. When the support plate 4 and the bottom sleeve 8 become loose due to support, the bottom sleeve 8 will drive the trigger frame 48 to move, so that the trigger frame 48 drives the rotating rod 37 to move, and the top end of the rotating rod 37 can squeeze the trigger block 28, so that the trigger block 28 drives the blocking block 31 to move out of the inner side of the semi-circular sleeve 23, and the bending spring 24 can use its own elastic force to drive the spherical body 25 to move along the inner side of the semi-circular sleeve 23, so that the spherical body 25 can impact the steel sheet 32, and a sound is generated inside the outer cover 33 through the impact of the steel sheet 32, so as to give a warning. At the same time, due to the impact, vibration is generated on the circular plate 22, so as to trigger the alarm 34 on the circular plate 22 to give an alarm, further warning the relevant staff, so that the staff can carry out maintenance work in the first time through the warning. When the rotating rod 37 rotates, the bottom end of the rotating rod 37 drives the trigger block 47 to move, so that the trigger block 47 drives the clamping strip 46 to move under the action of an external force, and the clamping strip 46 rotates around the second movable shaft 44 under the elastic support of the second torsion spring 45, so that the clamping strip 46 no longer engages with the outer shell 40, and the conical spring 41 uses its own elastic force to push the support plate 42 downward, so that the support plate 42 drives the shovel plate to move downward. At the same time, the second torsion spring 45 uses its own elastic force to drive the clamping strip 46 to rotate back to its original position, so that the shovel block 43 contacts the ground. When the support plate 4 supporting the reinforced concrete wall formwork becomes loose, the shovel block 43 supports the support plate 4 by shoveling into the ground.
