Description

Technical Field

[0001] This invention relates to the technical field of integrated retractable scaffolding anti-tipping devices, specifically an integrated retractable scaffolding anti-tipping device. Background Technology

[0002] Scaffolding is a working platform erected to ensure the smooth progress of various construction processes. It can be classified according to its location as external scaffolding and internal scaffolding; according to its material as wooden scaffolding, bamboo scaffolding, and steel pipe scaffolding; and according to its structural form as pole-type scaffolding, bridge-type scaffolding, frame-type scaffolding, suspended scaffolding, hanging scaffolding, cantilever scaffolding, and climbing scaffolding.

[0003] Currently, scaffolding is widely used in the construction industry, especially in the electromechanical decoration stage or small-scale construction. The safety of scaffolding is receiving increasing attention. Statistics show that most scaffolding safety accidents are caused by scaffolding overturning.

[0004] However, existing scaffolding does not come with anti-tipping devices at the factory and needs to be installed on-site. The existing scaffolding supports are all of fixed size, requiring the fabrication of various lengths of supports, which are independent of the scaffolding. Depending on the construction conditions of each work surface, multiple specifications of supports need to be carried for use, causing a lot of inconvenience to the workers. Furthermore, when changing the position of the scaffolding, the supports need to be repeatedly installed and disassembled, which is very cumbersome. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated retractable scaffolding anti-tipping device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a scaffold body, with a telescopic rod inserted into the top of the scaffold body, and a hinge shaft connected to the outer side of the top of the telescopic rod. A support is connected to the hinge shaft, and the support is inclined downward; and a fixed base, with a cavity in the middle of the bottom of the fixed base, a rotating shaft in the middle of the bottom of the cavity, a flipping block connected to the rotating shaft, through slots at two points of the flipping block, a first slot in the top of the inner side of the through slot, and a second slot in the bottom of the through slot.

[0007] Preferably, the telescopic rod can extend and retract at the top of the scaffold body to adjust the height of the scaffold body, and the extension and retraction of the telescopic rod can be fixed by inserting screws into screw holes aligned with the sides of the scaffold body and the telescopic rod.

[0008] Preferably, a horizontal tie rod is connected to the inner side of the bottom end of the hinge shaft, and the other end of the horizontal tie rod is connected to the outrigger. By controlling the extension and retraction length of the horizontal tie rod, the tilt angle between the outrigger and the scaffold body can be adjusted so that the hinge shaft is kept within 45° to 60°, which meets the requirements of the scaffold outrigger.

[0009] Preferably, the bottom of the outrigger is connected to a fixed base, and a flipping block is provided in the cavity at the bottom of the fixed base. The bottom of the flipping block has multiple sets of through holes, and the bottom of the through slots on both sides of the flipping block has a retaining groove. A telescopic block is provided in the retaining groove, and a rivet is provided at the bottom of the telescopic block. The rivet can extend out from the through hole.

[0010] Preferably, a knob is provided on the side of the fixed base, and the bottom of the knob is connected to the rotating shaft in the middle of the bottom of the through groove of the fixed base. Turning the knob can drive the flipping block connected to the rotating shaft to flip in the through groove.

[0011] Preferably, the top of the flipping block is provided with two sets of opposing support plates, and a roller is provided between the support plates. Multiple rollers are sleeved on the roller. By flipping the flipping block, the rollers at the top of the flipping block can be located at the bottom of the flipping block and extend out from the through groove opened at the bottom of the fixed base, so that the fixed base can be moved.

[0012] Preferably, springs are provided on both sides of the top of the flip block. The springs can use their contraction force to drive the telescopic block to rise and disengage from the retaining groove, so that the rivet at the bottom of the telescopic block retracts from the bottom of the flip block into the through groove.

[0013] Preferably, the fixed base has slots on both sides, and a retaining plate can be inserted into the slot. The retaining plate can be inserted into the first slot or the second slot opened inside the through slot of the flip block to retain the flip block and prevent the rotating shaft from causing the flip block to rotate in the through slot opened at the bottom of the fixed base due to non-human factors.

[0014] Preferably, the top outer side of the retaining plate is provided with a fixing hole, which is parallel to the screws inserted on both sides of the top of the fixing base. The screws can be inserted into the fixing hole to fix the retaining plate and prevent the retaining plate from coming out of the first slot or the second slot, so that the retaining plate can no longer limit the screws.

[0015] Preferably, the retaining plate has a sliding groove inside the fixing hole. The screw can press the retaining plate through the sliding groove, so that the retaining plate presses the telescopic block, so that the telescopic block is inserted into the retaining groove at the bottom of the flip block through groove and the rivet at the bottom of the telescopic block protrudes from the through hole.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This invention proposes an integrated telescopic scaffolding anti-tipping device. It involves inserting retaining plates into slots on both sides of a fixed base. The retaining plates are placed on top of telescopic blocks in the through slots on both sides of a tilting block. Then, by tightening the top screw of the fixed base, the screw descends and inserts into a sliding groove behind the fixing hole on the top of the retaining plate. Continuing to tighten the screw causes it to press against the retaining plate through the fixing hole. The retaining plate, under this pressure, begins to press against the telescopic block, causing it to insert into the retaining slot at the bottom of the through slot. In the middle, the second slot is exposed, and then the retaining plate is pushed inward to insert into the second slot, holding the telescopic block in place. At the same time, by pushing the retaining plate, the screw is inserted into the sliding groove, and then the screw is tightened to press the retaining plate. The rivet at the bottom of the telescopic block protrudes from the through groove through the through hole at the bottom of the flip block. Then, the fixed base is pressed down to insert the rivet into the soil, fixing the fixed base. The outrigger is fixed to the scaffold body through the fixed base to prevent the scaffold body from sliding. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1 to 5 This invention provides a technical solution: a scaffold body 1, with a telescopic rod 2 inserted into the top of the scaffold body 1, and a hinge shaft 3 connected to the outer side of the top of the telescopic rod 2. A support 4 is connected to the hinge shaft 3, and the support 4 is inclined downwards; and a fixed base 6, with a cavity in the middle of the bottom of the fixed base 6, and a rotating shaft 8 in the middle of the bottom of the cavity. A flipping block 9 is connected to the rotating shaft 8, and through slots are formed at two points of the flipping block 9. A first slot 14 is formed at the top of the inner side of the through slot, and a second slot 15 is formed at the bottom of the through slot. The telescopic rod 2 can extend and retract at the top of the scaffold body 1 to adjust the height of the scaffold body 1. The extension and retraction of the telescopic rod 2 can be fixed by inserting screws into screw holes aligned with the sides of the scaffold body 1 and the telescopic rod 2.

[0026] The bottom inner side of the hinge shaft 3 is connected to the horizontal tie rod 5, and the other end of the horizontal tie rod 5 is connected to the outrigger 4. By controlling the extension and retraction length of the horizontal tie rod 5, the tilt angle between the outrigger 4 and the scaffold body 1 can be adjusted so that the hinge shaft 3 is within 45° to 60°, which meets the requirements of the scaffold outrigger. The bottom of the outrigger 4 is connected to the fixed base 6. A flip block 9 is provided in the cavity opened at the bottom of the fixed base 6. Multiple sets of through holes 11 are opened at the bottom of the flip block 9. The bottom of the through slots opened on both sides of the flip block 9 is provided with a retaining slot. A telescopic block 10 is provided in the retaining slot. A rivet 12 is provided at the bottom of the telescopic block 10. The rivet 12 can protrude from the through hole 11. A knob 7 is provided on the side of the fixed base 6. The bottom of the knob 7 is connected to the rotating shaft 8 in the middle of the bottom of the through slot of the fixed base 6. Turning the knob 7 can drive the flip block 9 connected to the rotating shaft 8 to flip in the through slot.

[0027] The top of the flip block 9 is provided with two sets of opposing support plates 20, and a roller 21 is provided between the support plates 20. Multiple rollers 22 are sleeved on the roller 21. By flipping the flip block 9, the rollers 22 on the top of the flip block 9 can be located at the bottom of the flip block 9 and extend out from the through groove opened at the bottom of the fixed base 6, so that the fixed base 6 can be moved. Springs 23 are provided on both sides of the top of the flip block 9. The springs 23 can drive the telescopic block 10 to rise and disengage from the locking groove through the contraction force, so that the rivet 12 at the bottom of the telescopic block 10 retracts from the bottom of the flip block 9 into the through groove. Slots are opened on both sides of the fixed base 6. The locking plate 16 can be inserted into the slot. The locking plate 16 can be inserted into the first slot 14 or the second slot 15 opened inside the through groove of the flip block 9 to lock the flip block 9 and prevent the rotating shaft 8 from causing the flip block 9 to rotate in the through groove opened at the bottom of the fixed base 6 due to non-human factors.

[0028] A fixing hole 17 is provided on the top outer side of the retaining plate 16. The fixing hole 17 is parallel to the screws 19 inserted on both sides of the top of the fixing base 6. The screws 19 can be inserted into the fixing hole 17 to fix the retaining plate 16 and prevent the retaining plate 16 from detaching from the first slot 14 or the second slot 15, so that the retaining plate 16 can release the limiting effect on the screws 19. A sliding groove 18 is provided on the inner side of the retaining plate 16 in the fixing hole 17. The screws 19 can squeeze the retaining plate 16 through the sliding groove 18, so that the retaining plate 16 squeezes the telescopic block 10, so that the telescopic block 10 is inserted into the retaining groove at the bottom of the through groove of the flip block 9 and the rivet 12 at the bottom of the telescopic block 10 protrudes from the through hole 11.

[0029] In actual use, when using scaffolding for construction, first adjust the telescopic rod 2 according to the construction height so that the support platform reaches the appropriate position. Then fix the telescopic rod 2 with screws. After that, rotate the outrigger 4 through the hinge shaft 3 so that the hinge shaft 3 between the outrigger 4 and the scaffold body 1 is within 45° to 60° to meet the requirements of the scaffold outrigger. Then fix the horizontal tie rod 5 so that the horizontal tie rod 5 fixes the outrigger 4 and prevents the outrigger 4 from continuing to rotate.

[0030] If the construction site is in soft soil, insert the retaining plate 16 into the slots on both sides of the fixed base 6, place the retaining plate 16 on top of the telescopic block 10 in the through slots on both sides of the flip block 9, and then lower the screw 19 by screwing the top screw 19 of the fixed base 6. Insert the screw 19 into the sliding groove 18 provided behind the top fixing hole 17 of the retaining plate 16. Continue to screw the screw 19 so that the screw 19 presses the retaining plate 16 through the fixing hole 17. The retaining plate 16, through the pressing force, begins to press the telescopic block 10, so that the telescopic block 10 is inserted into the retaining slot opened at the bottom of the through slot, and the second After the slot 15 is exposed, the retaining plate 16 is pushed inward to insert it into the second slot 15, and the telescopic block 10 is held in the retaining plate. At the same time, the screw 19 is inserted into the sliding groove 18 by pushing the retaining plate 16, and then screwed (19) is tightened to make the screw 19 press the retaining plate 16. The rivet 12 at the bottom of the telescopic block 10 protrudes from the through groove through the through hole 11 at the bottom of the flip block 9. Then the fixed base 6 is pressed to insert the rivet 12 into the soil and fix the fixed base 6. The outrigger 4 is fixed to the scaffold body 1 through the fixed base 6 to prevent the scaffold body 1 from sliding.

[0031] When the ground is hard cement, the screw 19 can be disengaged from the sliding groove 18 by suspending the screw 19. Then, the retaining plate 16 can be pulled out. At this time, the springs 23 on both sides of the top of the telescopic block 10 will cause the telescopic block 10 to retract from the retaining groove, and at the same time, the rivet 12 at the bottom of the telescopic block 10 will retract into the through groove. Then, the retaining plate 16 can be inserted into the first slot 14, so that the retaining plate 16 continues to retain the flipping block 9 and prevent the flipping block 9 from rotating. The fixed base 6 passes through the through hole 11 at the bottom of the flipping block 9. The anti-slip plate 13 between the two surfaces is in close contact with the ground to prevent the fixed base 6 from sliding and causing the scaffold body 1 to slide. When it is necessary to move the scaffold body 1, the clamping plate 16 can be pulled out, and then the knob 7 can be turned so that the knob 7 drives the flipping block 9 to flip through the rotating shaft 8. The roller 22 on the inner side of the top of the flipping block 9 extends out from the through slot opened at the bottom of the fixed base 6, with the top layer on the ground. Then, by pushing the scaffold body 1, the roller 22 begins to move the scaffold body 1.
