DETAILED DESCRIPTION

[0041] Reference Figures 1 to 6 ,The present invention provides a technical solution: an anti-dumping protection safety device, comprising: a wire rod 1, a fixing component 2, and a lifting mechanism;

[0042] The fixing assembly 2 is detachably mounted on the wire rod 1 and is used to bear the working weight;

[0043] The lifting mechanism is connected to the fixing assembly 2 to assist the staff in the installation operation; specifically, the lifting mechanism includes: a connecting assembly 3, a load-bearing frame 4, a safety chair 5, a tool lifting assembly 7, and an anti-dumping assembly 8;

[0044] One end of the connecting component 3 is connected to the fixing component 2, and the other end is rotatably disassembled and connected to the load-bearing frame 4. The connecting component 3 is used to connect the fixing component 2 and the load-bearing frame 4; the safety chair 5 is fixedly installed on the load-bearing frame 4 for the convenience of the staff to sit;

[0045] The tool lifting assembly 7 is installed on both sides of the load-bearing frame 4 and is used to lift the tool;

[0046] One end of the anti-dumping assembly 8 is mounted on the connecting assembly 3, and the other end is detachably connected to the load-bearing frame 4, and is used to maintain the body balance of the staff when the staff abnormally dumps.

[0047] The worker first uses a climbing tool to fix the fixing component 2 to the pole 1. After the fixing is completed, the worker returns to the ground and connects the fixing component 2 with the connecting component 3. After the connection is completed, the worker sits on the safety chair 5 and is tied with a safety belt. The connecting component 3 is started, so that the worker slowly rises to the working height area.

[0048] When the operator accidentally falls forward or backward (due to strong winds, improper operation, etc.), the anti-falling assembly 8 will automatically lock under the action of centrifugal force, thereby preventing the occurrence of the falling phenomenon and maintaining the safety and stability of the operator.

[0049] When additional tools are needed, ground workers can transport their tools to the aerial workers via the tool lifting assembly 7 .

[0050] As a preferred embodiment, the connecting assembly 3 includes: a first shaft seat 31, a connecting plate 32, a second shaft seat 33, a third shaft seat 34, a first lifting roller 35, and an anti-fall device 37;

[0051] The first shaft seat 31 is fixedly mounted on the end of the load-bearing frame 4, and a load-bearing roller is arranged through the first shaft seat 31; one end of the second shaft seat 33 is rotatably arranged on the load-bearing roller, and the other end of the second shaft seat 33 is fixed to the connecting plate 32;

[0052] The third shaft seat 34 is fixedly mounted on the connecting plate 32, and the first lifting roller 35 is rotatably mounted on the third shaft seat 34, and the first lifting roller 35 is connected to the fixing assembly 2;

[0053] The anti-fall device 37 is fixed on the connecting plate 32 and is coaxially connected to the first lifting roller 35 .

[0054] As a preferred embodiment, there are two of each of the first axle seat 31 , the second axle seat 33 , and the third axle seat 34 , which are symmetrically installed to keep the load-bearing frame 4 horizontal and stable.

[0055] As a preferred embodiment, the first lifting roller 35 has a built-in driving motor.

[0056] It should be noted that the first lifting roller 35 is started to rotate, and the worker is kept in an optimal working height range by retracting or unwinding the first lifting rope 24. The second shaft seat 33 is rotatably connected to the connecting plate 32, so that the worker can rotate freely within a certain range, thereby improving the flexibility and portability of the worker.

[0057] The drive motor is preferably a conical rotor motor.

[0058] As a preferred embodiment, the anti-dumping assembly 8 includes: a centrifugal wheel 81, a fixing rod 82, and a second lifting rope 83;

[0059] The centrifugal wheel 81 is mounted on the connecting plate 32; the fixing rod 82 is fixed on the load-bearing frame 4;

[0060] One end of the second lifting rope 83 is connected to the centrifugal wheel 81 , and the other end is connected to the fixing rod 82 .

[0061] As a preferred embodiment, the number of the anti-dumping components 8 is two, and they are symmetrically arranged on the connecting plate 32 and the load-bearing frame 4, wherein the centrifugal wheels 81 are mirror-symmetrical.

[0062] As a preferred embodiment, the centrifugal wheel 81 includes: a limiting wheel 811, a rotating shaft 812, and a limiting rod 813;

[0063] The limiting wheel 811 is fixedly arranged on the connecting plate 32; the rotating shaft 812 is rotatably arranged on the connecting plate 32 and is coaxial with the limiting wheel 811, and a torsion spring 1 is arranged at the rotating shaft of the rotating shaft 812; the limiting wheel 811 is rotatably arranged on the rotating shaft 812, and a torsion spring 2 is arranged at the connection thereof;

[0064] One end of the second lifting rope 83 is wound around the rotating shaft 812 , and the other end is connected to the fixing rod 82 .

[0065] It should be explained that when the staff member falls backward or forward due to weather or personal factors, the fixing rod 82 will pull the second lifting rope 83 during the falling process, so that the second lifting rope 83 pulls the rotating shaft 812 to rotate rapidly, even if the limiting rod 813 rotates under the action of centrifugal force to overcome the torque of the second torsion spring, so that the limiting rod 813 is in contact and meshing with the limiting wheel 811, that is, the rotation of the rotating shaft 812 is limited, so that the staff member is fixed to prevent the falling phenomenon. When the staff member recovers the balanced working state, the second lifting rope 83 is always kept in a tensioned state under the action of the first torsion spring, and the limiting rod 813 releases the limiting effect between the limiting wheel 811 under the action of the second torsion spring, that is, the normal working state is restored.

[0066] It should be noted that when the staff is working at a normal rotation angle, the centrifugal force generated by the rotating shaft 812 cannot cause the limit rod 813 to deflect, thereby maintaining the flexibility of the staff's work.

[0067] As a preferred embodiment, the fixing assembly 2 includes:

[0068] A fixing ring 21 is detachably mounted on the wire rod 1, and a damping ring is disposed on its inner ring;

[0069] The bearing rod 22 is fixedly arranged on the fixing ring 21, and a fixing wheel 23 is fixedly arranged on the bearing rod 22;

[0070] One end of the first lifting rope 24 is connected to the fixed wheel 23 , and the other end is connected to the first lifting roller 35 .

[0071] It should be noted that when the first lifting roller 35 rotates, the first lifting rope 24 will be retracted or unwound, thereby achieving the lifting or lowering of the staff.

[0072] As a preferred embodiment, the tool lifting assembly 7 includes:

[0073] The second lifting roller 71 is rotatably arranged on the load-bearing frame 4 and is connected to the hook 72 through a third lifting rope. The required tool is hung on the hook 72, and then the second lifting roller 71 is started to lift the tool.

[0074] As a preferred embodiment, a remote control component 6 is detachably provided on the load-bearing frame 4 , and the remote control component 6 controls the first lifting roller 35 and the second lifting roller 71 through wireless signals.

[0075] During the specific implementation, the worker first uses a climbing tool to fix the fixing component 2 to the pole 1. After the fixation is completed, the worker returns to the ground and connects the fixing component 2 with the connecting component 3. After the connection is completed, the worker sits on the safety chair 5 and starts the first lifting roller 35. Under the winding or contraction of the first lifting rope 24, the worker is slowly raised to the working height area.

[0076] When the operator accidentally falls forward or backward (due to strong winds, improper operation, etc.), the anti-falling assembly 8 will automatically lock under the action of centrifugal force, thereby preventing the occurrence of the falling phenomenon and maintaining the safety and stability of the operator.

[0077] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
