Abstract
Description
Technical Field
[0001] This utility model relates to the field of protective device technology, specifically a fall protection device for high-altitude construction operations. Background Technology
[0002] A suspended platform is a construction tool used for high-altitude operations in building engineering, specifically for curtain wall installation and exterior wall cleaning. The cantilever mechanism is erected on a building or structure, using a lifting mechanism to drive a suspended platform that moves up and down along the building or structure's facade via steel wire ropes. It also serves as a work platform for operators. An existing high-altitude work safety device for construction (Announcement No.: CN221989866U) has the following disadvantages in use:
[0003] During use, the safety protection components can block falling objects and prevent them from injuring workers. However, while the safety protection components block falling objects, some of the falling objects are easy to roll off the components and are difficult to collect. The rolled objects will continue to fall, creating a risk of secondary falling objects. To address this problem, this patent proposes a fall protection device for high-altitude construction operations. Utility Model Content
[0004] The purpose of this utility model is to provide a fall protection device for high-altitude construction operations to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fall protection device for high-altitude construction operations, comprising a base, a guardrail fixed to the top of the base, multiple fixed rods installed on the outside of the guardrail, an installation rod fixed between the tops of the multiple fixed rods, a first fixed block rotatably connected to both ends of the installation rod, a protective plate fixed to the top of the first fixed block, a protective frame fixed to the top of the protective plate, a second fixed block fixed to the bottom of the protective plate, a connector fixed to the side of the fixed rod near the guardrail, a cylinder rotatably connected inside the connector, and the output end of the cylinder rotatably connected to the second fixed block.
[0006] Preferably, the outer side of the guardrail is equipped with multiple connecting shells, and the fixing rods correspond one-to-one with the connecting shells. The fixing rods are inserted into the connecting shells, and bolts are screwed between the fixing rods and the connecting shells.
[0007] Preferably, both ends of the mounting rod are provided with mounting grooves, and a first connecting rod is screwed into the mounting groove, and a first fixing block is rotatably connected to the outer wall of the first connecting rod.
[0008] Preferably, the output end of the cylinder is fixed with a first connecting ring, a second connecting rod is inserted between the second fixing block and the first connecting ring, a first nut is screwed onto the outer wall of the second connecting rod, and the second fixing block is rotatably connected to the second connecting rod.
[0009] Preferably, a second connecting ring is fixed to the bottom end of the cylinder, a third connecting rod is inserted into the connecting member, the third connecting rod is inserted into the second connecting ring, and a second nut is screwed onto one end of the third connecting rod on the outside of the connecting member.
[0010] Preferably, a gate is installed on the front of the guardrail.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] By activating the cylinder, the cylinder extends and drives the second fixed block to move. The second fixed block causes the side of the protective plate away from the mounting rod to rotate upward, causing the first fixed block to rotate around the mounting rod and adjust its angle to be in an inclined state. In this way, objects falling on the protective plate will roll onto the inner wall of the bottom of the protective frame and will not roll off the protective plate to the perimeter of the base. Furthermore, when it is necessary to clean objects from the protective plate, the cylinder retracts and the side of the protective plate away from the mounting rod rotates downward. This causes objects blocked by the protective frame to roll off the protective plate, preventing the accumulation of too many objects on the protective frame, which would increase the load on the protective frame and affect its safe load-bearing capacity.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Suspended platforms are construction tools used for high-altitude operations in building engineering, such as curtain wall installation and exterior wall cleaning. A cantilever mechanism is erected on a building or structure, using a lifting mechanism to drive a suspended platform, and moving up and down along the facade of the building or structure via steel wire ropes. It is also a work platform set up for operators. This utility model provides a fall protection device for high-altitude construction operations. By activating the cylinder 10, the cylinder 10 extends and drives the second fixing block 11 to move. The second fixing block 11 drives the protective plate 7 away from the mounting rod 5 to rotate upward, so that the first fixing block 6 rotates around the mounting rod 5 to adjust the angle and put it in an inclined state. In this way, objects falling on the protective plate 7 will roll onto the inner wall of the bottom end of the protective frame 8 and will not roll off the protective plate 7 to the perimeter of the base 1. Furthermore, when it is necessary to clear objects from the protective plate 7, the cylinder 10 retracts, and the protective plate 7 away from the mounting rod 5 rotates downward. In this way, objects blocked by the protective frame 8 will roll off the protective plate 7, preventing the accumulation of too many objects on the protective frame 8, which would increase the load on the protective frame 8 and affect the safe load-bearing capacity of the protective frame 8.
[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a fall protection device for high-altitude construction operations, including a base 1, a guardrail 2 fixed to the top of the base 1, multiple fixing rods 4 installed on the outside of the guardrail 2, an installation rod 5 fixed between the tops of the multiple fixing rods 4, a first fixing block 6 rotatably connected to both ends of the installation rod 5, a protective plate 7 fixed to the top of the first fixing block 6, a protective frame 8 fixed to the top of the protective plate 7, a second fixing block 11 fixed to the bottom of the protective plate 7, a connecting piece 9 fixed to the side of the fixing rod 4 near the guardrail 2, a cylinder 10 rotatably connected inside the connecting piece 9, and the output end of the cylinder 10 rotatably connected to the second fixing block 11.
[0021] It should be noted that by activating cylinder 10, cylinder 10 extends and drives the second fixing block 11 to move. The second fixing block 11 drives the protective plate 7 to rotate upward on the side away from the mounting rod 5, so that the first fixing block 6 rotates around the mounting rod 5 to adjust its angle and put it in an inclined state. In this way, objects falling on the protective plate 7 will roll onto the bottom inner wall of the protective frame 8 and will not roll off the protective plate 7 to the perimeter of the base 1. Furthermore, when it is necessary to clean the objects on the protective plate 7, cylinder 10 retracts and the side of the protective plate 7 away from the mounting rod 5 rotates downward. In this way, objects blocked by the protective frame 8 will roll off the protective plate 7, preventing the accumulation of too many objects on the protective frame 8, which would increase the load on the protective frame 8 and affect the safe load-bearing capacity of the protective frame 8.
[0022] like Figure 1 , Figure 3 and Figure 4 As shown, multiple connecting shells 12 are installed on the outer side of the guardrail 2. A fixing rod 4 corresponds to each connecting shell 12, and the fixing rod 4 is inserted into the connecting shell 12. Bolts 13 are screwed between the fixing rod 4 and the connecting shell 12. Both ends of the mounting rod 5 have mounting grooves, and a first connecting rod 14 is screwed into the mounting groove. A first fixing block 6 is rotatably connected to the outer wall of the first connecting rod 14. A first connecting ring is fixed to the output end of the cylinder 10. A second connecting rod 15 is inserted between the second fixing block 11 and the first connecting ring. A first nut 16 is screwed onto the outer wall of the second connecting rod 15, and the second fixing block 11 is rotatably connected to the second connecting rod 15. A second connecting ring is fixed to the bottom end of the cylinder 10. A third connecting rod is inserted into the connecting piece 9, and the third connecting rod is inserted into the second connecting ring. A second nut is screwed onto the outer side of one end of the third connecting rod located on the connecting piece 9. The first connecting rod 14, the second connecting rod 15, and the third connecting rod are similar, each having a threaded groove at one end. A gate 3 is installed on the front of the guardrail 2.
[0023] It should be noted that the fixing rod 4 is fixed to the connecting shell 12 by bolt 13, the first fixing block 6 at the bottom of the protective plate 7 is rotatably connected to one end of the mounting rod 5 by the first connecting rod 14, and the second fixing block 11 at the bottom of the protective plate 7 is rotatably connected to the first connecting ring by the second connecting rod 15 and the first nut 16. When the protective plate 7 is damaged later, it is only necessary to rotate out the first connecting rod 14, then rotate out the first nut 16 from the second connecting rod 15 and pull out the second connecting rod 15 to disassemble the protective plate 7.
