[0001] The invention relates to the technical field of climbing tools, and in particular to a magnetic footrest for a tower wall and a use method thereof. Background Art

[0002] The maintenance and overhaul of wind turbine tower walls is the key to ensuring the normal operation of wind turbines. Traditional maintenance and overhaul operations generally require operators to use suspended safety ropes to enter the work area for operations, but the above-mentioned operation method has limited fixing effect, and the operator's torso also lacks stable support, which not only increases the safety risk of the operation, but also significantly reduces the operation efficiency.

[0003] Therefore, in order to ensure the stability and safety of workers during high-altitude operations, there are currently designs that use simple foot pedals that use strong magnets and pedals to provide workers with more stable support at heights, thereby improving stability and safety during high-altitude operations.

[0004] However, after the operation is completed, the footrests magnetically attracted to the tower wall of the wind turbine need to be disassembled and recovered. In order to ensure the magnetic attraction firmness during climbing operations, the magnetic attraction force of the magnets is often relatively large, which makes it difficult for operators to disassemble the footrests conveniently and easily by manpower alone. In addition, the overall volume of the existing footrests fixed with magnets is generally relatively large, which is not convenient for operators to climb and carry. As a result, the current footrests have problems such as low disassembly and assembly efficiency, inconvenient use, and inconvenient carrying. Summary of the invention

[0005] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art and to provide a magnetic footrest for a tower wall and a method for using the same.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] A magnetic foot pedal for a tower wall comprises a fixing frame, a magnet arranged on the fixing frame, and a pedal. The fixing frame is provided with a positioning hole and a fixing hole corresponding to the position of the pedal. The pedal is provided with an insertion strip plugged into the fixing hole and a rotatably arranged support frame. The insertion strip passes through the fixing hole and is provided with a block abutting against the fixing frame. The insertion rod of the support frame is plugged and fixed in the positioning hole.

[0008] Preferably, the fixing hole is provided with a socket, and a pin is plugged into the socket.

[0009] Preferably, the size of the insertion hole is larger than the size of the fixing hole.

[0010] Preferably, a second bolt is threadedly mounted on the fixing frame, and a nut of the second bolt presses against the supporting frame to limit the insertion rod to the positioning hole.

[0011] Preferably, the magnet and the pedal are arranged on two sides of the fixing frame opposite to each other, and the fixing frame is provided with a bolt 1 for threadedly connecting the magnet.

[0012] Preferably, the number of the magnets is two, and both magnets are provided with a magnetic attraction surface, and the installation angle of the magnet can be adjusted by rotating the bolt.

[0013] Preferably, a through hole is provided on the fixing frame.

[0014] A method for using a magnetic footrest for a tower wall comprises the following steps:

[0015] a. Clamp the clamping teeth of the clamping plate upward into the through hole of the fixing frame, and abut the limit fixing frame downward through the abutment pin, and fix the fixing frame on the tower wall through the magnet;

[0016] b. Turn the handle in the direction of S2 so that the magnetic surface of the magnet is flat and adheres to the tower wall;

[0017] c. Pull the abutment pin outwards so that the latching teeth can be disengaged from the through hole downwards, and drive the latching plate and the turning handle away from the fixing frame;

[0018] d. Set the pedal in a vertical position, drive the insert strip to insert through the fixing hole, and then rotate the pedal horizontally to clamp the pedal to the fixing frame through the clamping block;

[0019] e. Rotate the support frame to insert and fix the plug rod of the support frame into the positioning hole to realize the installation and use of the magnetic footrest;

[0020] f. When the magnetic pedal needs to be removed, the support frame is rotated in the opposite direction to disengage the insertion rod from the positioning hole, and then the horizontal pedal is rotated to keep the pedal in a vertical state and move away from the fixing frame until the insertion rod is disengaged from the fixing hole;

[0021] g. Re-engage the latching teeth upward and fix them in the through hole, and abut against the limit fixing frame downward through the abutment pin;

[0022] h. Turn the handlebar in the direction of S1 to gradually separate the magnet attached to the tower wall from the tower wall to remove the magnetic pedal.

[0023] Preferably, in step e, after the insertion rod is inserted and fixed in the positioning hole, the second bolt is tightened so that the nut of the second bolt presses and fixes the support frame.

[0049] That is, the magnet 2 is fixed to the fixing frame 1 by rotating the bolt 11, and the angle of the magnetic surface 21 of the two magnets 2 can be adjusted by using the bolt 11, so that the magnet 2 can adapt to the tower wall with different curvatures, and then the magnet 2 can better fit and be fixed on the tower wall by magnetic attraction, so that the magnetic footrest of this embodiment can better meet the use requirements of climbing operations, and make the magnetic footrest in this embodiment safer and more reliable to use, avoiding the safety hazard caused by the magnetic surface 21 not fitting the tower wall.

[0050] The pedal 3 is detachably fixed horizontally on the fixing frame 1, and a positioning hole 14 and a fixing hole 15 corresponding to the position of the pedal 3 are opened on the fixing frame 1. The positioning hole 14 and the fixing hole 15 are opened on the fixing frame 1 relatively to each other up and down. The pedal 3 is provided with an insertion strip 31 inserted into the fixing hole 15 and a rotatably arranged support frame 33. The insertion strip 31 passes through the fixing hole 15 and is provided with a block 32 abutting against the fixing frame 1.

At this time, the pedal 3 is slightly displaced upward, and the insertion rod 331 of the support frame 33 is inserted and fixed in the positioning hole 14, so that the support frame 33 is inserted and fixed on the positioning hole 14 to horizontally support the pedal 3.

[0053] Furthermore, by providing a detachable pedal 3, the magnetic footrest of this embodiment is more convenient for operators to carry and use when climbing, so that operators can load and unload more quickly, enter and exit the working area, thereby further improving the efficiency of aerial work.

[0054] Furthermore, through the magnetic installation setting of the magnet 2, the magnetic footrest of this embodiment can be quickly installed and positioned, and the operation can be carried out quickly without relying on external support ropes, thereby simplifying the preparation work for the operation.

[0055] Furthermore, by cooperating with the magnet 2 and the pedal 3, it is ensured that the operator can stand firmly on the tower wall to perform work, so as to reduce safety accidents caused by unstable support, so that the operator does not need to hang in the air for a long time, and the pedal 3 can provide stable support for high-altitude work, which reduces the labor intensity of high-altitude work and improves the safety and efficiency of the operator during work.

[0056] Furthermore, a plug hole 16 is provided on the fixing hole 15 , and the plug hole 16 is provided above the fixing hole 15 and communicated with the fixing hole 15 .

[0062] Furthermore, a pin hole 531 is opened in the pin seat 53, and a support plate 61 threadedly connected to the abutment pin 6 is arranged in the pin hole 531. The support plate 61 is abutted with a spring 62 located in the pin hole 531. The spring 62 abuts against the support plate 61 to drive one end of the abutment pin 6 to always maintain a tendency to penetrate the pin seat 53.

The locking plate 5 is provided with a slot hole 54 corresponding to the position of the throttle handle 7, and the throttle handle 7 is penetrated by the slot hole 54, that is, the throttle handle 7 passes through the slot hole 54 and extends to the rear side.

[0064] The handle 7 is provided with a roller 71 distributed on the same side as the latching tooth 51 , and the roller 71 is abutted against the tower wall for loading and unloading, so that the loading and unloading tool of the magnetic pedal in this embodiment is more convenient and smooth to use.

[0065] When the magnetic pedal of this embodiment needs to be installed or removed, the handle 7 is rotated to drive the magnet 2 on the fixing frame 1 away from or magnetically attracted to the tower wall (refer to Fig.14 ), realizes the rapid disassembly and magnetic fixation of the magnet 2, so that the operators can disassemble and fix it more conveniently, that is, it is convenient for the operators to quickly enter and exit the working area, so as to avoid the operators having to rely on manpower to forcibly load and unload the magnetic foot pedal at high altitude, thereby reducing the labor intensity of loading and unloading operations while improving the safety and efficiency of high-altitude operations.

[0066] The engaging plate 5 is provided with a notch 55 , and the notch 55 is configured to avoid the second bolt 12 on the fixing frame 1 .

Clamp the clamping teeth 51 of the clamping plate 5 upwardly into the through hole 13 of the fixing frame 1, and abut the limiting fixing frame 1 downwardly through the abutting pin 6 to achieve the fixed limit of the fixing frame 1, and the fixing frame 1 is fixed to the tower wall by the magnet 2 (refer to Fig.14 status shown);

[0069] b. Turn the handle 7 in the direction S2 so that the magnetic surface 21 of the magnet 2 is flatly magnetically attached to the tower wall, so that the magnet 2 is stably and reliably set on the tower wall;

[0070] c. Pull the abutting pin 6 outwards. At this time, the abutting pin 6 no longer abuts against the limit fixing frame 1 downwards, that is, the engaging plate 5 can move downwards, so that the latching teeth 51 can be disengaged from the through hole 13 downwards, and the engaging plate 5 and the turning handle 7 are driven away from the fixing frame 1;

[0071] d. Set the pedal 3 in a vertical position (refer to Figure 3 As shown), in fact, at this time, the pedal 3 is in a slightly inclined vertical state, and the inserting strip 31 is driven to insert through the fixing hole 15, so that the block 32 passes through the fixing hole 15, and then the pedal 3 is rotated horizontally (so that the pedal 3 remains Figure 6 The pedal 3 is clamped and limited to the fixing frame 1 by the clamping block 32, so as to limit the front and rear separation of the pedal 3 from the fixing frame 1;
