[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses a hydraulic climbing formwork ratchet type one-way tightening anti-fall safety device.

[0034] Reference Figure 1 and Figure 2 A hydraulic climbing formwork ratchet type one-way tightening anti-fall safety device includes a climbing frame 1, a guide rail 2, a hanging shoe 3, a pulling mechanism 4 and a lifting mechanism 5. The guide rail 2 is arranged in the vertical direction, and a sliding member 6 is arranged on one side of the guide rail 2. The guide rail 2 is slidably matched with the building outer wall 8 through the sliding member 6. The pulling mechanism 4 is arranged on one side of the building outer wall 8. The pulling mechanism 4 is used to pull the guide rail 2 to a specified position along the vertical direction.

[0035] Reference Figure 1 and Figure 3 The lifting mechanism 4 includes a one-way ratchet 41, a connecting member 42 and a chain 43. The connecting member 42 is pre-buried in one side of the building outer wall 8. The one-way ratchet 41 is rotatably connected to the connecting member 42. The chain 43 is wound around the outer periphery of the one-way ratchet 41. Therefore, the arrangement of the one-way ratchet 41 and the chain 43 is conducive to driving the chain 43 to rotate stably in one direction. In the present embodiment application, the chain 43 rotates counterclockwise.

[0036] Reference Figure 1 One end of the guide rail 2 is fixedly connected to the chain 43. As the one-way ratchet 41 rotates in one direction, the chain 43 is driven to move in one direction. Through the movement of the chain 43, the guide rail 2 is driven to move in the vertical direction, which is beneficial to ensure the stability of the movement of the guide rail 2. The climbing frame 1 is fixedly connected to the guide rail 2. When the guide rail 2 moves in one direction with the chain 43, the chain 43 moves in one direction. The movement of the guide rail 2 is beneficial to drive the climbing frame 1 to move. When the climbing frame 1 is subjected to force, the setting of the one-way ratchet 41 is beneficial to preventing the chain 43 from rotating in the opposite direction, which is beneficial to ensure the stability of the guide rail 2, ensure the stability of the climbing frame 1, and then ensure the safety of the climbing frame 1.

[0037] Reference Figure 1 The hanging shoe 3 is arranged on one side of the building outer wall 8, and a fastener 7 is arranged on one side of the hanging shoe 3. The fastener 7 is pre-buried in the building outer wall 8, and the hanging shoe 3 is fixed to one side of the building outer wall 8 through the fastener 7. When the hanging shoe 3 is fixed to the specified position through the fastener 7, the guide rail 2 is assisted by the hanging shoe 3 to be fixed to one side of the building outer wall 8, so that the climbing frame 1 is stressed by the hanging shoe 3 and the guide rail 2 together, which is conducive to dispersing the load borne by the climbing frame 1, and then it is conducive to ensuring the force balance of the climbing frame 1 and ensuring the safety of the climbing frame 1.

[0038] Reference Figure 1 and Figure 2 The jacking mechanism 5 includes a jacking assembly 51 and a jacking cylinder 52. In the present embodiment, two groups of jacking assemblies 51 are provided. Both groups of jacking assemblies 51 are provided on one side of the slide rail, one group of jacking assemblies 51 is provided on the output end of the jacking cylinder 52, and the other group of jacking assemblies 51 is provided on the side of the jacking cylinder 52 away from the output end of the jacking cylinder 52. The provision of two groups of jacking assemblies 51 and the jacking cylinder 52 is conducive to ensuring that the climbing frame 1 can be stably transported in the vertical direction. First, the jacking component 51 on the output end side of the jacking cylinder 52 cancels the limit on the jacking cylinder 52, and the jacking cylinder 52 jacks up the other group of jacking components 51 and the climbing frame 1. After the jacking of the other group of jacking components 51 is completed, the slide rail is locked for limiting. At this time, the jacking cylinder 52 contracts to retract one of the jacking components 51, thereby stably climbing the climbing frame 1 to the top. The progressive climbing is conducive to ensuring the stability of the climbing frame 1 during climbing, ensuring the stable climbing of the climbing frame 1, and thus ensuring the safety of the climbing frame 1 during movement.

The reversing component 513 includes a reset spring 5131, a reversing side plate 5132 and a positioning hanging plate 5133. The jacking frame 511 is arranged in the vertical direction. The jacking frame 511 is engaged with one side of the guide rail 2 through the jacking ratchet 512. The jacking frame 511 is fixedly connected to one end of the jacking cylinder 52. The jacking ratchet 512 is rotatably connected to the jacking frame 511. The guide rail 2 is arranged in the vertical direction. The guide rail 2 is provided with positioning teeth 21. A plurality of positioning teeth 21 are arranged along the length direction of the guide rail 2. The plurality of positioning teeth 21 are equidistantly and evenly arranged on the outer periphery of the guide rail 2. Through the cooperation of the ratchet and the plurality of positioning teeth 21, it is beneficial to ensure the stability of the jacking frame 511, thereby ensuring the stability of the climbing frame 1.

The reversing side plate 5132 is coaxially fixed with the lifting ratchet 512. When the climbing frame 1 moves downward, the positioning plate 5133 is rotated to drive the return spring 5131 to deform, and drive the reversing ratchet to rotate, which is beneficial to ensure the stability and effectiveness of the climbing frame 1 when it moves downward through the reversing ratchet, thereby ensuring the stability of the device.

[0041] Reference Figure 1A wire mesh 9 is provided at the bottom of the climbing frame 1, and the wire mesh 9 is used to receive falling objects from high altitude to ensure the safety of the device, which is beneficial to prevent the falling objects from high altitude from affecting the ground. A wire rope 10 is provided on one side of the chain 43, and one end of the wire rope 10 is fixedly connected to the chain 43, and the end of the wire rope 10 away from the chain 43 is fixedly connected to the climbing frame 1.
