Description

Technical Field

[0001] The utility model belongs to the technical field of high-altitude operation protection, in particular to a simple high-altitude operation mobile protection frame. Background Art

[0002] The mobile protective frame is a movable safety equipment designed specifically for high-altitude operations. Its main purpose is to provide certain protective measures for the edge working area and ensure the personal safety of high-altitude workers.

[0003] When users perform overhead work on bus rooftops, some bus roofs may have limited load-bearing capacity. Furthermore, the rooftops may contain complex pipelines, equipment, or structural components, making it difficult for safety ropes to find suitable mounting points or fixtures. This results in users lacking the necessary protective measures while working on the rooftop, significantly increasing the risk of injury or death in the event of an accident (such as a slip or fall). In light of this, we propose a simple mobile safety frame for overhead work. Utility Model Content

[0061] Example 5:

[0062] This embodiment provides a simple mobile protective frame for aerial work. In addition to the technical solutions of the above embodiments, it also has the following technical features. The fixing assembly includes:

[0063] The third slide groove 17 is opened in the fixed plug block 12 and is connected to the outside world. An insertion rod 18 is slidably connected in the third slide groove 17, and one end of the insertion rod 18 extends to the inner wall of the slot 7 and is plugged into the slot 7. A spring 19 fixed to the inner wall of the third slide groove 17 is fixedly connected to the insertion rod 18.

[0064] Among them, the user presses two inserting rods 18 with hands, and makes one end of each of the two inserting rods 18 enter into two third sliding grooves 17 respectively from the inner walls of two slots 7, and compresses two springs 19 respectively. At this time, the fixation of two fixed inserting blocks 12 is released. Subsequently, the user slides the second support rod 10 with hands, and makes the second support rod 10 slide reversely along the first sliding groove 9. When the second support rod 10 moves to a proper position, the second support rod 10 will drive one end of one fixed inserting block 12 to move from one slot 7 to the outside. Subsequently, the user pulls the first support rod 8 with hands, and makes the first support rod 8 drive one end of the other fixed inserting block 12 to move from the other slot 7 to the outside. Subsequently, the user replaces the first support rod 8 and the second support rod 10 with the first support rod 8 and the second support rod 10 with appropriate lengths to fix the first support 1 and the second support 2, prevent the first support 1 and the second support 2 from approaching each other, and ensure that the user can quickly replace the first support rod 8 and the second support rod 10 with the first support rod 8 and the second support rod 10 with appropriate lengths.

[0065] Embodiment 6:

[0066] This embodiment provides a simple mobile protective frame for high-altitude work. In addition to including the technical solutions of the above embodiments, it also has the following technical features that the inserting rod 18 is in an inverted "匸" shape.

[0067] Among them, it is ensured that the user can drive one end of the inserting rod 18 to move through the other end of the inserting rod 18.

[0068] During use, the user pulls the first support 1 and the second support 2 respectively according to the length of the passenger car, and makes the first support 1 and the second support 2 move away from each other. When the first support 1 and the second support 2 move away from each other, the first support 1 and the second support 2 will respectively pull both ends of two telescopic rods 3 to elongate the two telescopic rods 3. At the same time, the first support 1 and the second support 2 will also drive the telescopic protective net 4 to unfold. When the first support 1 and the second support 2 move away from each other, the second support 2 will drive the second support rod 10 to slide in the first sliding groove 9. When the first support 1 and the second support 2 move to proper positions, the user rotates the bidirectional threaded rod 16 with hands, and makes two extrusion blocks 14 approach each other under the action of two sections of threads on the bidirectional threaded rod 16. When the two extrusion blocks 14 move to positions where they cannot move, the two extrusion blocks 14 will clamp and fix the second support rod 10 in the first sliding groove 9 and make it unable to move, ensuring that the second support rod 10 can be fixed in the first sliding groove 9 and unable to move. Subsequently, the user moves the whole device, and makes multiple universal wheels 5 roll on the ground, facilitating the user to move the whole device to a proper position;

[0069] When the distance between the first bracket 1 and the second bracket 2 is short, the user rotates the two-way threaded rod 16 in the opposite direction by hand, so that the two extrusion blocks 14 are moved away from each other by the two sections of thread on the two-way threaded rod 16. When the two extrusion blocks 14 move to the appropriate position, the two extrusion blocks 14 will release the fixation of the second support rod 10. Then the user presses the two insertion rods 18 by hand, so that one end of the two insertion rods 18 respectively enters the two third sliding grooves 17 from the inner walls of the two slots 7, and compresses the two springs 19 respectively. At this time, the fixation of the two fixed insertion blocks 12 is released, and then the user slides the second support rod 10 by hand to make it slide in the opposite direction along the first sliding groove 9. When When the second support rod 10 is moved to the appropriate position, the second support rod 10 will drive one end of one of the fixed plug blocks 12 to move from one of the slots 7 to the outside, and then the user will pull the first support rod 8 by hand to allow the first support rod 8 to drive one end of the other fixed plug block 12 to move from the other slot 7 to the outside, and then the user will replace the first support rod 8 and the second support rod 10 with the first support rod 8 and the second support rod 10 of appropriate length to fix the first bracket 1 and the second bracket 2 to prevent the first bracket 1 and the second bracket 2 from approaching each other, ensuring that the user can quickly replace the first support rod 8 and the second support rod 10 with the first support rod 8 and the second support rod 10 of appropriate length.

[0070] The embodiments of the present application are described above in conjunction with the accompanying drawings. Unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
