A slowing power device for building climbing formwork and its usage method

Abstract

This invention discloses a slowing power device for climbing scaffolding and its usage method. The device includes a climbing scaffold body and a traction machine mounted on the upper surface of the climbing scaffold body. A hanging frame is slidably connected to the inner wall of the climbing scaffold body. A round rod is fixedly connected to the output end of the traction machine. A positioning plate is fixedly connected to the upper surface of the climbing scaffold body. The right end of the round rod is rotatably connected to the left side of the positioning plate. A winding roller is fixedly connected to the surface of the round rod, and steel cables are wound around the surface of the winding roller. In this slowing power device for climbing scaffolding, when the traction machine slows the round rod through its own reduction gearbox, the motor drives the two bidirectional lead screws to rotate. The two bidirectional lead screws, through two movable blocks and two transmission rods, drive two braking blocks close to the surface of the round rod. The friction between the lead screws and the round rod provides a slowing assistance to the traction machine, ensuring that in the event of traction machine failure, the hanging frame can be slowed down and buffered, thus improving safety.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on 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.

[0026] Please see Figures 1-3 The present invention provides a technical solution: a building climbing formwork slowing power device, including a climbing formwork body 1 and a traction machine 2 installed on the upper surface of the climbing formwork body 1. A hanging frame 3 is slidably connected to the inner wall of the climbing formwork body 1. A round rod 4 is fixedly connected to the output end of the traction machine 2. A positioning plate 5 is fixedly connected to the upper surface of the climbing formwork body 1. The right end of the round rod 4 is rotatably connected to the left side of the positioning plate 5. A winding roller 6 is fixedly connected to the surface of the round rod 4. A steel cable 7 is wound on the surface of the winding roller 6. The end of the steel cable 7 away from the winding roller 6 is fixedly connected to the upper surface of the hanging frame 3. An auxiliary slowing component is fixedly connected to the upper surface of the climbing formwork body 1.

[0027] The traction machine 2 drives the lifting frame 3 to move up and down on the inner wall of the climbing frame body 1 through the round rod 4, the winding roller 6 and the steel cable 7, and controls the speed of the round rod 4 through the reduction gearbox of the traction machine 2 to ensure the stability of the lifting frame 3.

[0028] The auxiliary deceleration component includes a positioning frame 8. A rectangular hole is opened on the side of the positioning frame 8. The position of the round rod 4 corresponds to the position of the rectangular hole on the side of the positioning frame 8. Two fixed cavities are opened inside the positioning frame 8. The inner walls of the two fixed cavities are rotatably connected to a bidirectional lead screw 9. A motor is installed on the upper surface of the positioning frame 8. The output end of the motor is fixedly connected to the top end of either bidirectional lead screw 9. Two movable blocks 10 are slidably connected to the inner wall of the fixed cavity. The two movable blocks 10 are respectively threaded to the positive and negative threads on the surface of the bidirectional lead screw 9. The ends of the two movable blocks 10 away from the inner wall of the fixed cavity are rotatably connected to a transmission rod 11. Movable grooves adapted to the transmission rod 11 are opened on the front and rear inner walls of the rectangular hole.

[0029] The end of the transmission rod 11 away from the movable block 10 is rotatably connected to the brake block 12, and the positions of the two brake blocks 12 correspond to the positions of the round rod 4. The surfaces of the two bidirectional lead screws 9 are fixedly connected to the sprockets 13, and the surfaces of the two sprockets 13 are connected to the chain 14. The inside of the positioning frame 8 is provided with a strip groove that matches the chain 14.

[0030] When the traction machine 2 drives the round rod 4 at a slow speed through the gearbox, the motor can drive the two double-acting screws 9 to rotate through the sprocket 13 and chain 14. The two double-acting screws 9 can drive the two movable blocks 10 to move towards the opposite surface, and through the transmission rod 11, drive the two brake blocks 12 to approach the surface of the round rod 4. The friction between the brake blocks 12 and the round rod 4 can provide a slowing assistance to the gearbox of the traction machine 2. Even if the traction machine 2 is damaged, the brake blocks 12 can still provide a slowing function for the hanging frame 3, ensuring the safety of the hanging frame 3 during use.

[0031] Positioning frames 15 are fixedly connected to both the left and right sides of the climbing frame body 1. Hydraulic cylinders 16 are fixedly connected to the sides of the positioning frames 15. A moving plate 17 is slidably connected to the inner wall of the positioning frames 15. A fall arrestor plate 18 is fixedly connected to the side of the moving plate 17. A strip hole adapted to the fall arrestor plate 18 is opened on the side of the climbing frame body 1. Two springs 19 are fixedly connected between the side of the climbing frame body 1 and the side of the moving plate 17.

[0032] Under normal circumstances, the hydraulic cylinder 16 drives the moving plate 17 away from the side of the climbing frame body 1 and causes the spring 19 to deform. When a power failure occurs during the project, the hydraulic cylinder 16 loses its restraint on the moving plate 17. After the spring 19 loses its restraint, it can drive the moving plate 17 closer to the side of the climbing frame body 1. At this time, the moving plate 17 can drive the anti-fall plate 18 through the strip hole and lock it in the inner wall of the climbing frame body 1, so that the hanging frame 3 provides a support force for the hanging frame 3 during the descent, ensuring that it will not fall directly, and improving the safety of the personnel inside and below the hanging frame 3.

[0033] The following improvements are made based on the above embodiments: Figures 4 to 8As shown, a fall protection structure is installed on the top of the climbing frame body 1. The fall protection structure is located on the outside of the round rod 4. The fall protection structure includes a drive disc 41 installed on the round rod 4 and a brake structure slidably installed on the top of the climbing frame body 1. A one-way transmission body 42 (pawl) is installed on the drive disc 41. The brake structure includes a fixing member 43 whose lateral position relative to the top of the climbing frame body 1 is adjustable. The fixing member 43 is installed by a sliding plate installed on the top of the climbing frame body 1 and its position is fixed by bolts. A sleeve 45 fitted onto the outside of the round rod 4 is installed on the top of the fixing member 43, and the sleeve 45 and the fixing member 43 form a one-way transmission engagement through a ratchet and pawl. The sleeve 45 rotates when the steel cable 7 is wound up and jams (does not rotate) when the cable is unwound. A sliding sleeve 46 is installed inside the sleeve 45. The sleeve 46 houses a drive body 44 (ratchet), which is adapted to form a one-way transmission engagement with the one-way transmission body 42. Both the drive disc 41 and the sliding sleeve 46 have sloping structures on opposite sides. The sliding sleeve 46 is located on the outside of the round rod 4. A spacer 47 is installed inside the sleeve 45, and a spring 48 connects the spacer 47 and the sliding sleeve 46. A positioning ring 49, fitted onto the outside of the round rod 4, is fixed inside the sleeve 45. The spacer 47 is located between the sliding sleeve 46 and the fixing ring 49. The positioning ring 49 and the sliding sleeve 46 are connected by multiple circumferentially distributed universal joint rods 410, with each universal joint rod 410 having the same inclination direction. Both ends of the universal joint rod 410 are universal joint structures, which are connected to the corresponding disc by bolts. A pressure-bearing part is installed between the spring 48 and the sliding sleeve 46. This pressure-bearing part is part of the sliding sleeve 46 and is assembled with the sliding sleeve 46 body via rollers or balls. The outer side of the sliding sleeve 46 is provided with a guide block, and the inside of the sleeve 45 is provided with a guide groove that gradually approaches the spacer 47 along the axial direction. The guide groove and the guide block are adapted to each other.

[0034] A polyurethane wear-resistant rubber sleeve 411 is installed between the sliding sleeve 46 and the positioning ring 49, or the outer wall of the universal hinge rod 410 is wrapped with a polyurethane wear-resistant rubber layer. The appropriate design structure is determined according to the specific implementation method.

[0035] When the traction machine 2 on the climbing frame body 1 drives the hanging frame 3 upward, the one-way transmission body 42 and the drive body 44 are matched and synchronized. The traction machine 2 drives the steel cable 7 to move the hanging frame 3 upward. When the traction machine 2 fails and the hanging frame 3 is passively lowered, the round rod 4 and the winding roller 6 will lower the steel cable 7 in the opposite direction. The one-way transmission body 42 and the drive body 44 rotate relative to each other, causing the drive body 44 to move the sliding sleeve 46 laterally and rotate at the same time. The sliding sleeve 46 is compressed by the spring 48 through the ramp structure, and finally the round rod 4 is tightly wrapped and locked by the universal hinge rod 410. Then, the motor drives the double-acting screw 9 to clamp the brake block 12 to hold the round rod 4. Finally, the round rod 4 is clamped and fixed to release the lateral pressure of the fixing part 43. When the traction machine 2 on the climbing frame body 1 drives the hanging frame 3 to actively lower, the lateral sliding fixing part 43 separates the drive body 44 and the one-way transmission body 42, and the drive disc 41 and the sliding sleeve 46 are completely separated.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
