Description

Technical Field

[0001] This utility model relates to the field of high-altitude operation technology, and in particular to a high-altitude operation safety protection platform. Background Technology

[0002] Aerial work safety protection platforms are auxiliary equipment used in high-altitude work scenarios. They are widely used in fields such as building construction, power maintenance, and curtain wall installation. By providing a stable working plane and protective barriers, they ensure the safety of workers in high-altitude environments. The platform can adjust its height through a lifting mechanism to adapt to different work needs, while the protective railings prevent people from falling. It is a key facility for balancing efficiency and safety in high-altitude operations, and can centrally carry workers, tools, and materials, reducing the risk factor of high-altitude operations.

[0003] Existing work platforms bear weight through an overall rigid structure, relying on bottom support legs to distribute the load and prevent collapse due to excessive stress at a single point. During operation, workers and materials are placed in the same area of ​​the platform, and the platform's structural strength enables transportation and operation. When transporting workers and materials, both are concentrated at the same work point, increasing the local load on the platform. Because the platform structure uses rigid structural components to bear weight, the concentrated weight area will disrupt the original force balance, resulting in an imbalance in the left-right load ratio of the platform. As operations continue, this imbalance will cause the platform to tilt towards the heavily loaded side, not only affecting operational stability but also potentially exceeding the load-bearing limit of the support legs, causing the platform to shake or even overturn, posing a threat to the safety of workers. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0033] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a high-altitude work safety protection platform, including a platform support 1, a fence 2 fixedly connected to the top outer side of the platform support 1, a balance adjustment mechanism 3 provided in the upper middle part of the front side of the fence 2, the balance adjustment mechanism 3 is used to adjust the overall left and right balance of the platform, a door frame 4 is rotatably connected to the right side of the platform support 1, an opening and closing mechanism 5 is provided between the front side of the door frame 4 and the fence 2, the opening and closing mechanism 5 is used to fix the door frame 4, and an anti-slip mechanism 6 is designed on the top of the platform support 1.

[0034] The balance adjustment mechanism 3 includes an adjustment rod 31, which is fixedly connected to the upper middle part of the front side of the fence 2. Multiple counterweights 32 are slidably connected to the outside of the adjustment rod 31. Adjustment holes 33 are opened on the left and right sides of the multiple counterweights 32. The multiple counterweights 32 are slidably connected to the outside of the adjustment rod 31 through the adjustment holes 33. Sliding claws 34 are fixedly connected to the upper and lower ends of the multiple counterweights 32. The multiple sliding claws 34 are slidably connected to the top and middle of the front side of the fence 2, respectively. A locking component 35 is provided inside the adjustment hole 33. The locking component 35 includes multiple mounting slots 351. The multiple mounting slots 351 are opened at the top and bottom left and right ends of the inner side of the multiple adjustment holes 33, respectively. Spring telescopic pins 352 are fixedly connected inside the multiple mounting slots 351. Multiple positioning holes 353 are equidistantly opened at the top and bottom of the adjustment rod 31.

[0035] Specifically, in the balance adjustment mechanism 3, the adjustment rod 31 is fixed to the upper middle part of the front side of the fence 2, and multiple counterweights 32 are slidably connected to the outside of the adjustment rod 31 through the adjustment hole 33. The sliding claw 34 slides at the top and middle of the front side of the fence 2. The spring telescopic pin 352 is fixed in the mounting groove 351 inside the adjustment hole 33, which cooperates with the positioning holes 353 at the top and bottom of the adjustment rod 31.

[0036] When the platform experiences a large difference in the left and right weight ratio, the counterweight 32 is pushed to slide along the adjusting rod 31 in the opposite direction of tilt. The sliding claw 34 slides along the fence 2 to provide guidance, ensuring that the movement trajectory of the counterweight 32 is stable. During the movement, the spring telescopic pin 352 is squeezed and contracted by the adjusting rod 31, disengaging from the current positioning hole 353.

[0037] When the counterweight 32 moves to the target position, the spring telescopic pin 352 aligns with the corresponding positioning hole 353 and pops out, locking and fixing the relative position of the counterweight 32 and the adjusting rod 31; multiple counterweights 32 can move individually or in combination, and the tilting tendency of the platform can be counteracted by changing the overall center of gravity position.

[0038] The locking action of the spring telescopic pin 352 and the positioning hole 353 prevents the counterweight 32 from sliding when the platform vibrates. The gap between the adjusting hole 33 and the adjusting rod 31 controls the lateral displacement of the counterweight 32. The contact between the sliding claw 34 and the fence 2 enhances the anti-overturning ability of the counterweight 32 and avoids lateral displacement when moving.

[0039] The weight of the counterweight 32 is transmitted to the fence 2 through the adjusting rod 31, which in turn affects the force balance of the platform support 1. By adjusting the distribution position of the counterweight 32, the overall center of gravity of the platform is placed near the central axis. The fence 2 provides structural support for the balance adjustment mechanism 3 to ensure overall stability during the adjustment process.

[0040] The design of multiple counterweights 32 allows for phased adjustment of balance to accommodate different tilt levels; the elastic properties of the spring telescopic pin 352 make the movement and fixing of the counterweights 32 convenient and can be completed without additional tools.

[0041] The rigid structure of the adjusting rod 31 ensures the effective transmission of gravity of the counterweight 32, and the equidistant distribution of the positioning holes 353 provides multiple adjustment options to meet the balance adjustment needs under different working scenarios; the sliding connection of the sliding claw 34 reduces the friction when the counterweight 32 moves, while restricting its degree of freedom.

[0042] The balance adjustment mechanism 3 adjusts the platform's center of gravity by changing the weight distribution. Combined with the protective function of the fence 2, it prevents the platform from tilting and causing workers to fall, greatly enhancing the safety and stability of high-altitude operations.

[0043] Reference Figure 1 , Figure 4 and Figure 5 The opening and closing mechanism 5 includes a U-shaped connector 51, which is fixedly connected to the right side of the fence 2. A connecting piece 52 is fixedly connected to the front side of the door frame 4. The external dimensions of the connecting piece 52 match the internal dimensions of the U-shaped connector 51. A fixing ring 53 is fixedly connected to the upper middle part of the right side of the fence 2. A spring rope 54 is provided on the outside of the fixing ring 53. A fixing pin 55 is provided at the bottom end of the spring rope 54. The end of the fixing pin 55 passes through the interior of the U-shaped connector 51 and the connecting piece 52. The opening and closing mechanism 5 also includes a pressing piece 56, which is fixedly connected to the bottom end of the fixing pin 55.

[0044] Specifically, in the opening and closing mechanism 5, the U-shaped connector 51 is fixed to the right side of the fence 2, and the connecting piece 52 on the front side of the door frame 4 matches the size of the U-shaped connector 51; the fixing ring 53 in the upper middle part of the right side of the fence 2 is connected to the spring rope 54, and the fixing pin 55 at the bottom of the spring rope 54 passes through the U-shaped connector 51 and the connecting piece 52, and the bottom end is fixed with the pressing piece 56.

[0045] When the door frame 4 is closed, the connecting piece 52 is embedded inside the U-shaped connector 51, and the two fit together to form a limiting structure; pulling the fixing pin 55 stretches the spring rope 54, aligning the fixing pin 55 with the through hole of the U-shaped connector 51 and the connecting piece 52, and releasing it causes the spring rope 54 to retract, driving the fixing pin 55 to insert into the hole.

[0046] After the fixing pin 55 passes through, the pressing piece 56 fits against the outside of the U-shaped connector 51, restricting the axial movement of the fixing pin 55; the tension of the spring rope 54 keeps the fixing pin 55 in the inserted state, preventing vibration from causing it to fall off.

[0047] When the door frame 4 is opened, pulling the pressing plate 56 causes the fixing pin 55 to disengage from the through hole, and the spring rope 54 generates elastic potential energy as it is stretched. After the fixing pin 55 is removed, the connecting piece 52 is released from the constraint of the U-shaped connector 51, and the door frame 4 can rotate around the platform support 1. The size matching between the U-shaped connector 51 and the connecting piece 52 ensures a tight fit and limits the lateral displacement of the door frame 4. The fixing ring 53 provides a fixed fulcrum for the spring rope 54, ensuring the stability of the pulling force direction. The through-hole design of the fixing pin 55 rigidly connects the U-shaped connector 51 and the connecting piece 52, transmitting the external force on the door frame 4 to the fence 2. The pressing plate 56 increases the hand grip area, making it easier to operate the fixing pin 55. The elastic characteristics of the spring rope 54 cause the fixing pin 55 to automatically reset during operation without the need for additional fixing steps. Its length limits the range of motion of the fixing pin 55 to prevent loss.

[0048] When the door frame 4 is closed, the opening and closing mechanism 5 connects the door frame 4 and the fence 2 into a whole, enhancing the continuity of the protective structure; when open, the fixing pin 55 is suspended by the spring rope 54, which does not affect the rotation of the door frame 4; the U-shaped structure of the U-shaped connector 51 provides upper and lower limits for the connecting piece 52, and together with the axial fixation of the fixing pin 55, it realizes multi-directional constraint of the door frame 4; the rigidity of the connecting piece 52 ensures that it does not deform under force, ensuring the reliability of the fixation;

[0049] The opening and closing mechanism 5, through the combination of mechanical pin and elastic reset, enables the rapid fixing and opening of the door frame 4, and works in conjunction with the fence 2 and platform support 1 to form a closed protective space to prevent the door frame 4 from accidentally opening and falling during operation.

[0050] Reference Figure 1 , Figure 2 and Figure 6 The anti-slip mechanism 6 includes multiple station plates 61, and multiple connecting rods 62 are equidistantly connected inside the multiple station plates 61; the multiple station plates 61 are all designed in a sheet shape, and their tops are all designed with anti-slip grooves; a fall protection net 7 is fixedly connected to the rear side of the fence 2, and the surface holes of the fall protection net 7 are designed in a hexagonal shape; mounting frames 8 are fixedly connected to the front, rear, left and right ends of the platform support 1, and square tube reinforcing ribs 9 are fixedly connected inside the multiple mounting frames 8, and the square tube reinforcing ribs 9 are designed in an I-shaped structure.

[0051] Specifically, in the anti-slip mechanism 6, multiple platform plates 61 are fixed together by connecting rods 62 to form a platform standing surface; the platform plates 61 adopt a sheet-like design to reduce the overall weight, and the anti-slip grooves on the top increase the contact friction with the soles of the shoes; when the workers stand, the soles of the shoes fit into the anti-slip grooves, and the edges of the grooves prevent the feet from sliding relative to each other. By changing the roughness of the contact surface, the anti-slip effect is improved. The connecting rods 62 connect the platform plates 61 into a whole to distribute the stepping force.

[0052] The hexagonal holes on the surface of the fall protection net 7 behind the fence 2 form a continuous protective surface. When the workers lean back for a short rest, their bodies come into contact with the fall protection net 7. The hexagonal structure disperses the impact force through the edges of the holes, and the net stretches to generate elastic deformation to absorb energy, thus limiting the tendency of people to fall.

[0053] The mounting brackets 8 on the front and rear sides of the platform support 1 have internally fixed square tube reinforcing ribs 9. The I-shaped structure enhances the bending resistance of the mounting brackets 8. The platform remains stable under stress, and the connection with the platform support 1 enhances the overall structural rigidity. The mounting brackets 8 transfer the load to the square tube reinforcing ribs 9. The I-shaped cross-section disperses stress through the upper and lower flanges, reducing deformation.

[0054] Working principle: Before operation, the door frame 4 is opened by the opening and closing mechanism 5: pulling the pressing plate 56 causes the fixing pin 55 to disengage from the U-shaped connector 51 and the connecting plate 52, the spring rope 54 is stretched, and the door frame 4 rotates around the platform support 1 to open; after the operator enters, the door frame 4 is closed, so that the connecting plate 52 is embedded in the U-shaped connector 51, the fixing pin 55 is released, the spring rope 54 retracts and drives it through the two, the pressing plate 56 is attached and fixed, forming a closed protective space;

[0055] Workers stand on the anti-slip mechanism 6 on the platform 61, with the soles of their shoes fitting against the anti-slip grooves on the top of the platform 61. The grooves increase friction to prevent slipping. The connecting rod 62 connects the platform 61 into a whole, dispersing the stepping force. If the platform tilts to the left or right, the counterweight 32 of the balance adjustment mechanism 3 is pushed to slide in the opposite direction of the tilt along the adjustment rod 31. The sliding claw 34 is guided along the fence 2, and the spring telescopic pin 352 disengages from the original positioning hole 353.

[0056] After the counterweight 32 is in place, the spring telescopic pin 352 pops out and engages with the corresponding positioning hole 353 to fix the position and adjust the center of gravity of the platform to counteract the tilting trend; multiple counterweights 32 can be combined and moved to ensure that the center of gravity is near the central axis.

[0057] During operation, if a person leans towards the rear of the fence 2 and their body comes into contact with the fall protection net 7, the hexagonal holes disperse the impact force through the edges, and the deformation of the net absorbs energy, preventing a fall; when the platform support 1 is under stress, the I-shaped square tube reinforcing ribs 9 in the mounting frame 8 disperse the stress, enhance the overall rigidity, and reduce deformation;

[0058] When the position needs to be adjusted, repeat the balance adjustment steps and maintain balance by moving the counterweight 32; after the operation is completed, pull the pressing plate 56 again to open the door frame 4, and close the door frame 4 after the personnel leave. The fixing pin 55 is reset and fixed under the action of the spring rope 54.

[0059] The balance adjustment mechanism 3 adjusts the center of gravity of the dynamic balance platform by adjusting the position of the counterweight 32, and the spring telescopic pin 352 and the positioning hole 353 ensure stability after adjustment; the opening and closing mechanism 5 realizes the quick opening and closing of the door frame 4 through the mechanical pin and elastic reset, ensuring safe entry and exit;

[0060] The anti-slip groove of the anti-slip mechanism 6 and the integrated design of the connecting rod 62 not only prevent slipping but also disperse the force of stepping; the hexagonal structure of the fall protection net 7 enhances the rear protection and absorbs impact energy; the mounting frame 8 and the square tube reinforcing rib 9 improve the overall structural strength of the platform and resist various loads during operation.

[0061] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
