Description

Technical Field

[0001] This utility model belongs to the technical field of fall protection equipment, and in particular relates to a movable safety fall protection net device. Background Technology

[0002] Currently, in order to achieve full load, the stacking height of packaged goods on trucks during loading and unloading operations in railway freight yards often exceeds 2 meters. According to the "Safety Technical Rules for Railway Freight Loading and Unloading," when manual labor is used to load, unload, or stack goods on trucks, and the standing position extends beyond the side of the truck and is more than 2 meters above the ground, protective fences (nets) or safety belts must be used for protection.

[0003] However, many loading and unloading companies do not equip themselves with protective fences (nets) and safety belts in order to save costs. The design and use of protective fences (nets) provided by a few contracted companies are also inappropriate, which greatly reduces the safety protection effect. If personnel and goods fall from the stacks during the operation, it will cause serious personal injury accidents and damage to the goods. Utility Model Content

[0017] 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.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Reference Figures 1-2 As shown, this embodiment provides a movable safety fall prevention net device, including a first frame with a vertical net, a second frame for placing a horizontal net is hinged to one side of the first frame, a limiting mechanism is provided between the second frame and the first frame, a support mechanism is symmetrically hinged to the side of the first frame away from the second frame, and a moving mechanism is fixed to the bottom of the first frame.

[0020] The main frame supports the vertical safety net to form a vertical protection, while the hinged second frame can be unfolded to form a horizontal safety net. The support mechanism provides lateral stability, and the moving mechanism enables the overall displacement of the device. This utility model integrates the functions of a vertical and horizontal safety net, lowering the center of gravity and increasing safety; it also prevents workers from falling from heights and avoids damage caused by falling goods.

[0021] The scheme is further optimized. The first frame includes two first columns 1. A first crossbeam 2 is fixed between the top surfaces of the first columns 1. A second crossbeam 3 is fixed between the two first columns 1. The second crossbeam 3 is located below the first crossbeam 2. A vertical net is provided between the first crossbeam 2 and the second crossbeam 3. A moving mechanism is fixed to the bottom surface of the first column 1. A second frame and a moving mechanism are respectively hinged to the first column 1.

[0022] The first column 1 and the crossbeam form a rigid main structure, while the second crossbeam 3 provides an intermediate support point, creating installation space for the vertical netting. The moving mechanism is directly integrated into the bottom of the column, and the support rod 14 enhances the stability of the frame, enabling "moving-fixed" dual-mode switching.

[0023] Further optimization of the scheme: the second frame includes a first hinge seat 4 that is fixedly connected to the first column 1. The first hinge seat 4 is located close to the second crossbeam 3. The second column 5 is hinged inside the first hinge seat 4. The end of the second column 5 away from the first hinge seat 4 is fixedly connected to the third crossbeam 6. A limiting mechanism is provided between the outer side of the second column 5 and the first column 1. A flat net is provided between the third crossbeam 6 and the second crossbeam 3.

[0024] The first hinge seat 4 serves as a rotation fulcrum. After the second column 5 unfolds around the axis, the third crossbeam 6 and the second crossbeam 3 are tensioned with a flat net to form a horizontal protective surface.

[0025] The scheme is further optimized. The limiting mechanism includes a chain link 7 set on the outside of the second column 5, and a limiting rod 8 fixed to the outside of the first column 1. The chain link 7 and the limiting rod 8 are adapted to each other.

[0026] When the flat net is opened to any angle between 0-90°, the chain link 7 on the second column 5 is hung on the limiting rod 8 to limit the second frame.

[0027] The scheme is further optimized. The support mechanism includes a second hinge seat 9 that is fixedly connected to the first column 1. The second hinge seat 9 is located above the second crossbeam 3. An electric telescopic rod 10 is hinged inside the second hinge seat 9. An abutment seat 11 is hinged to the output end of the electric telescopic rod 10.

[0028] The electric telescopic pole 10 adjusts the support angle via the second hinge seat 9, and the output end automatically adjusts the extension length according to ground undulations. The abutment seat 11 increases the contact area, and the electronic control system can adjust the support pressure in real time to ensure stability under different terrains.

[0029] The scheme is further optimized. The moving mechanism includes a connecting plate 12 that is fixedly connected to the bottom surface of the first column 1. Universal wheels 13 are installed at both ends of the bottom surface of the connecting plate 12. Support rods 14 are symmetrically fixedly connected to the top surface of the connecting plate 12. The support rods 14 are fixedly connected to the first column 1.

[0030] The combination of the first frame and the deployable second frame creates a dual protection system of vertical and horizontal safety netting. The integration of the electric support mechanism and the moving mechanism allows the device to quickly adapt to different operating scenarios.

[0031] The design was further optimized by attaching a safety belt hook 15 to the top surface of the first crossbeam 2. The hook of the operator's safety belt is then attached to the safety belt hook 15, improving the operator's safety during work.
