Description

Technical Field

[0001] The utility model relates to the technical field of high-altitude operation safety protection, in particular to a high-altitude operation safety protection device for construction engineering. Background Art

[0002] Aerial work usually refers to high-altitude work, which refers to the work performed by people at a height based on a certain position. If there is a requirement for high-altitude work during the construction process, a work platform will be needed. The aerial work platform is also an indispensable construction process in building construction projects.

[0003] There are many types of aerial work platforms currently available. For example, China Patent No. CN201920809133.1 is a construction aerial work platform. This patent is provided with a fixed platform and a mobile platform that moves inside it. The load-bearing assembly provided on the mobile platform makes the positioning piece and the positioning groove cooperate to lock the mobile platform to prevent overload and subsequent safety accidents. The load-bearing assembly includes a load-bearing plate, a spring column, a lifting rod, a second telescopic rod, a rotating shaft, and a gear connected to the rotating shaft and driving the positioning piece. The gravity borne by the load-bearing plate drives the lifting rod to move down and then rotates the rotating shaft through the second telescopic rod to drive the positioning piece up through the gear. Then, the mobile platform extends outward, causing the second telescopic rod to extend outward and driving the rotating shaft and the gear thereon to rotate to move the positioning piece up. When the mobile platform moves to the set extension value (under a certain gravity on the load-bearing plate), the positioning piece cooperates with the positioning groove to lock the mobile platform. At this time, the overload phenomenon of the extended part of the mobile platform is prevented, effectively ensuring the safety of construction workers. The positioning piece includes a sliding connection on the fixed platform. The large end inside and the small end outside the fixed platform are connected as a whole, the top of the large end matches the positioning groove, and a side wall of the small end is provided with teeth, and the teeth and the gear are engaged to enable the positioning piece to move up accurately. At the same time, the teeth and the gear are located on the outside of the fixed platform for easy assembly and maintenance. A first guardrail is provided on the fixed platform and a second guardrail is provided on the mobile platform to ensure the safety of construction workers. The mobile platform is driven to move left and right by a hydraulic cylinder installed in the fixed platform, and a first telescopic rod provided on the first guardrail is connected to the second guardrail to assist in stabilizing the mobile platform. The mobile platform is locked in combination with the load-bearing component. When the slider cooperates with the positioning piece, the hydraulic cylinder overloads and stops working; after the two are separated, the hydraulic cylinder is started again to drive the mobile platform to extend or retract into the fixed platform. However, since this patent is similar to the protection measures of most work platforms on the market, the protection is not comprehensive. This type of device can only provide protection for those workers standing on the platform. If the personnel need to leave the work platform or suddenly fall off the platform, serious accidents will still occur. Utility Model Content

The safety rope 206 is fixedly connected to the winding roller 205. 06 is fixedly connected to the end away from the winding roller 205 with a hinge 207, wherein the hinge 207 can connect the two objects through a hinge to ensure that the relative position between the objects is fixed and prevent the objects from falling off or dislocating during movement. At the same time, the hinge 207 allows the two connected objects to perform relative movement, such as rotation, swinging, etc. The end of the hinge 207 away from the safety rope 206 is fixedly connected to an arc-shaped clamp 208, and the two sides of the arc-shaped clamp 208 are respectively fixedly connected to a first buckle 209 and a connecting block 210, a second clip 211 is hinged on the connecting block 210, wherein the connection relationship between one end of the second clip 211 and the first clip 209 is a clip connection, and the end of the second clip 211 away from the first clip 209 is fixedly connected to the return spring 212, and the end of the return spring 212 away from the second clip 211 is fixedly connected to the inner wall of the arc-shaped fixture 208. By arranging the arc-shaped fixture 208, the first clip 209, the connecting block 210, the second clip 211 and the return spring 212, the mechanism can be It is connected to the staff by a snap-on connection. When the staff connects the protective mechanism 2 to themselves, if danger occurs, the driving motor 202 cooperates with the first bearing 203 to make the transmission rod 204 rotate stably, and then the stable rotation of the transmission rod 204 drives the winding roller 205 to recycle the safety rope 206. At the same time, the staff connected to the other end of the safety rope 206 will be pulled toward the work platform together, thereby effectively avoiding serious accidents. It is highly practical.

[0024] In the implementation of the case, the right side of the work platform body 1 is movably connected with the platform safety door 3, and the platform safety door 3 is provided with a locking mechanism, which includes an adjusting cavity 301. The interior of the platform safety door 3 is provided with an adjusting cavity 301, and two second bearings 302 and an auxiliary limit rod 306 are fixedly installed inside the adjusting cavity 301. The interior of the two second bearings 302 is penetrated by a rotating rod 303, and hand wheels 304 are fixedly installed on both sides of the rotating rod 303. A gear 305 is fixedly installed on the rotating rod 303, and then by arranging the second bearing 302, the rotating rod 303, the hand wheel 304 and the gear 305, the staff can make the rotating rod 303 rotate stably by rotating the hand wheels 304 on both sides, and the rotating rod 303 will also drive the gear 305 to rotate in the same way.

By providing the semi-arc fixing plate 601, the fixing rod 602 and the auxiliary support rod 603, it is helpful to increase the cross-sectional height of the support plate 4 in the vertical direction, thereby improving its overall strength.

[0027] During implementation, follow these steps:

[0028] 1) Press the second buckle 211 to separate it from the first buckle 209;

[0029] 2) Then, the arc-shaped fixture 208 is buckled onto the worker's clothing or object;

[0030] 3) Release the second buckle 211 and use the rebound characteristics of the return spring 212 to reset the second buckle 211;

[0031] 4) Finally, check whether the clamp end and the safety rope 206 are suitable. If there is no problem, high-altitude operation can be carried out.

[0032] In summary, the construction engineering high-altitude operation safety protection device, by setting up a protection mechanism 2, first sets an arc-shaped clamp 208, a first clamp 209, a connecting block 210, a second clamp 211 and a return spring 212, so that the mechanism can be connected to the staff by a clamping method. After the staff connects the protection mechanism 2 to themselves, if a danger occurs, the driving motor 202 cooperates with the first bearing 203 to make the transmission rod 204 rotate stably, and then the stable rotation of the transmission rod 204 drives the winding roller 205 to recycle the safety rope 206. At the same time, the staff connected to the other end of the safety rope 206 will be pulled toward the work platform together, thereby effectively avoiding serious accidents. It is highly practical and solves the problem that this patent is similar to the protection measures of most work platforms on the market, and the protection is not comprehensive. This type of device can only provide protection for those workers standing on the platform. If the personnel need to leave the work platform or suddenly fall off the platform, a serious accident will still occur.
