Description

Technical Field

[0001] This invention relates to the field of electrical work safety equipment technology, specifically to a safety pole climbing foot pedal system and its usage method. Background Technology

[0002] In power industry work, workers often need to climb utility poles to perform tasks. The pole climbing foot is a crucial tool for this work, and its safety directly impacts the personal safety of the workers. The climbing device utilizes leverage; by using the weight of the person, one side is firmly attached to the utility pole, generating significant friction that makes climbing easier. When the foot is lifted, the weight on the foot decreases, and the hook automatically releases, utilizing the self-locking phenomenon in mechanics.

[0003] However, existing pole climbing foot pedals often lack detection and restriction of the grounding wire connection status during use. This may lead to workers using the pole climbing foot pedals for pole climbing operations even when the grounding wire is not connected or is not securely connected, thereby increasing the safety risks such as electric shock or lightning strikes.

[0004] Therefore, how to prevent this situation from occurring is an urgent problem to be solved. Summary of the Invention

[0005] This invention provides a safe pole climbing foot pedal system and its usage method. The system prohibits the use of the pole climbing foot pedal when the grounding wire is not connected or is not securely connected, thereby ensuring the safety of workers when climbing poles.

[0006] This invention is achieved through the following technical solution:

[0007] A safe pole climbing foot pedal system includes:

[0008] The pole climbing foot pedal includes a buckle mechanism that contacts or separates from the utility pole and a foot pedal. The foot pedal includes a strap and safety boxes disposed opposite to each other on both sides of the foot pedal. The two ends of the strap extend into the interior of the safety box through openings provided in the safety box. Each of the two safety boxes is provided with a first control mechanism for controlling the strap to loosen or tighten.

[0009] The grounding wire status signal detection module is installed on the grounding wire to detect the status of the grounding wire and send the detected status signal as a detection signal to the grounding wire status signal receiving module.

[0010] A grounding wire status signal receiving module is installed on the pole climbing foot pedal and is used to receive the detection signal from the grounding wire status signal detection module and transmit it to the controller.

[0011] A memory, installed on the pole-climbing foot pedal, is used to record the status information of the first control mechanism at the previous moment;

[0012] A controller, installed on the climbing foot pedal, is used to control the first control mechanism to loosen or tighten the straps based on the detection signal and the status information of the first control mechanism.

[0013] As an optimization, the buckle mechanism includes a first buckle body, a second buckle body, a sliding sleeve, and a connecting rod. The first buckle body is fixedly connected to one end of the connecting rod, the sliding sleeve is slidably sleeved on the connecting rod, and the second buckle body is fixedly connected to the sliding sleeve. The first buckle body and the second buckle body are arranged opposite to each other, and the sliding sleeve is fixedly connected to the connecting rod through a fastening mechanism.

[0014] As an optimization, the fastening mechanism includes a fastening bolt, a stop block, and a nut. Elongated holes are respectively provided through opposite sidewalls of the connecting rod, and a threaded hole is provided through one sidewall of the sliding sleeve. The internal thread of the nut is opposite in direction to the threaded hole. The fastening bolt is threadedly connected to the threaded hole, and extends sequentially through the threaded hole and the two elongated holes into the interior of the sliding sleeve. The stop block is fixedly connected to the inner sidewall of the sliding sleeve, and is positioned opposite the elongated hole away from the threaded hole. The nut is threadedly connected to the end of the connecting rod away from the threaded hole, and abuts against the stop block to restrict the rotation of the nut.

[0015] As an optimization, the first control mechanism includes a first motor fixed to the inner side wall of the safety box. The first motor is electrically connected to the controller. The axis of the first rotating shaft of the first motor is parallel to the upper surface of the foot pedal, and the axis of the first rotating shaft of the first motor is perpendicular to the line connecting the two safety boxes. The first rotating shaft is fixedly connected to one end of the strap, and the strap is wrapped around the first rotating shaft.

[0016] As an optimization, a clamping mechanism is also provided on the two long sidewalls opposite to the opening. The long sidewalls of the opening are recessed inward and provided with a first groove. A clamping plate is slidably provided in the first groove. A driving mechanism is installed on the two sides of the clamping plate adjacent to the opening to move the clamping plate toward or away from the opening.

[0017] As an optimization, the drive mechanism includes a second motor, a roller, and a mounting plate. The second motor is electrically connected to the controller. The mounting plate is fixedly connected to the side wall of the clamping plate, and the second motor is mounted on the mounting plate. The axial direction of the second rotating shaft of the second motor is parallel to the opening direction of the opening. The second rotating shaft passes through the mounting plate and is fixedly connected to the roller. The roller contacts the side wall of the first groove.

[0018] As an optimization, it also includes a first anti-slip pad disposed on the side of the first buckle body near the second buckle body and a second anti-slip pad disposed on the side of the second buckle body near the first buckle body.

[0019] This invention also discloses a method of using a safety pole climbing foot pedal system, comprising:

[0020] The grounding wire status signal detection module detects the status of the grounding wire and sends the detected status signal as a detection signal to the grounding wire status signal receiving module.

[0021] The grounding wire status signal receiving module will receive the detection signal and transmit it to the controller;

[0022] The controller controls the first control mechanism to loosen or tighten the straps based on the detection signal and the status information of the first control mechanism stored in the memory.

[0023] As an optimization, the state information of the first control mechanism is specifically the state information of the first motor. The state information of the first motor includes an initial state and a rotational state. When the first motor is in the initial state, the strap is loosened; when the first motor is in the rotational state, the strap is tightened. The specific process by which the controller controls the first control mechanism to perform the loosening or tightening operation of the strap based on the detection signal and the state information of the first control mechanism stored in the memory is as follows:

[0024] S1. The status information of the first motor before the grounding wire is connected is transmitted to the memory for storage, and at the same time, the storage signal of the memory is transmitted to the controller.

[0025] S2. Connect the grounding wire and detect it through the grounding wire status signal detection module. Transmit the detection signal to the controller through the grounding wire status signal receiving module.

[0026] S3. When the detection signal is not hooked or poorly hooked and the status information of the first motor is in the initial state, the controller controls the first shaft of the first motor to rotate so that the first motor becomes rotating, thereby tightening the strap. Then, the status information of the first motor is transmitted to the memory to replace the original status information of the first motor stored in the memory.

[0027] When the detection signal is not hooked or poorly hooked and the status information of the first motor is in the rotating state, the controller controls the first motor to remain stationary, so that the strap remains in a tightened state, and then transmits the status information of the first motor to the memory to replace the original status information of the first motor stored in the memory.

[0028] When the detection signal indicates stable connection and the status information of the first motor is in the initial state, the controller controls the first motor to remain stationary, keeping the strap loose, and then transmits the status information of the first motor to the memory to replace the original status information of the first motor stored in the memory.

[0029] When the detection signal indicates stable connection and the status information of the first motor is in a rotating state, the controller controls the first motor to rotate back to its initial state, thereby loosening the strap. Then, the status information of the first motor is transmitted to the memory to replace the original status information of the first motor stored in the memory.

[0030] As an optimization, the controller also controls the rotation of the second motor based on the detection signal and the state information of the first control mechanism. When both second motors are in their corresponding long-stop positions, the straps are clamped between the two clamping plates. The state information of the first control mechanism is specifically the state information of the first motor, which includes an initial state and a rotational state, specifically:

[0031] When the detection signal is not connected or poorly connected, and the status information of the first motor is in the initial state, the controller controls the second motor to rotate, causing the clamping plate to move away from the opening. After the status information of the first motor changes, the controller controls the second motor to rotate in the opposite direction, causing the clamping plate to move closer to the opening, and finally the second motor is in the long-term stop position.

[0032] When the detection signal is not connected or poorly connected and the status information of the first motor is rotating, the controller controls the second motor to remain stationary, so that the second motor is in a long-term stop position;

[0033] When the detection signal is stable and the status information of the first motor is in the initial state, the controller controls the second motor to remain stationary, so that the second motor is in a long-term stop position;

[0034] When the detection signal indicates stable connection and the first motor's status information indicates rotation, the controller controls the second motor to rotate, causing the clamping plate to move away from the opening. After the status information of the first motor changes, the controller controls the second motor to rotate in the opposite direction, causing the clamping plate to move closer to the opening, ultimately placing the second motor in a stationary position.

[0035] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0036] This invention controls the loosening or tightening of the straps through a first control mechanism, making the maximum gap between the straps and the foot pedal very small, preventing the worker's foot from passing through the gap. In other words, when the straps are tightened, the worker's foot cannot pass through the straps, thus preventing the foot from being fixed to the foot pedal. This can prompt the worker to check if the grounding wire is connected properly and can also prevent workers from working in violation of regulations. Attached Figure Description

Detailed Implementation

[0050] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0051] This embodiment 1 provides a safe pole-climbing foot pedal system, such as Figure 1 As shown, it includes:

[0052] The pole climbing foot pedal includes a buckle mechanism that contacts or separates from the utility pole and a foot pedal 4. The foot pedal 4 includes a strap 6 and a safety box 7 disposed on both sides of the foot pedal 4. The two ends of the strap 6 extend into the interior of the safety box 7 through an opening 7a. The two safety boxes 7 are respectively provided with a first control mechanism for controlling the strap 6 to loosen or tighten.

[0053] Grounding wire status signal detection module I is installed on the grounding wire to detect the status of the grounding wire and send the detected status signal as a detection signal to grounding wire status signal receiving module II;

[0054] Grounding wire status signal receiving module II is installed on the climbing foot pedal and is used to receive the detection signal of the grounding wire status signal detection module I and transmit it to the controller III; the grounding wire status signal detection module I sends the detection signal to the grounding wire status signal receiving module II through wireless communication technology.

[0055] Memory IV, installed on the pole climbing foot pedal, is used to record the status information of the first control mechanism at the previous moment;

[0056] Controller III, installed on the climbing foot pedal, is used to control the first control mechanism to loosen or tighten the strap 6 based on the detection signal and the status information of the first control mechanism.

[0057] Controller III is electrically connected to ground wire status signal receiving module II, memory IV, and the first control mechanism, respectively.

[0058] The first control mechanism controls the loosening or tightening of strap 6. Tightening strap 6 here means that the exposed length of strap 6 is very short, resulting in a very small maximum gap between strap 6 and foot pedal 4. This prevents the worker's foot from passing through the gap, meaning that when strap 6 is tightened, the worker's foot cannot pass through it, thus failing to secure the foot to foot pedal 4. This serves as a prompt to the worker to check if the grounding wire is properly connected and can prevent workers from violating regulations. Visually, tightened strap 6 appears as taut strap 6.

[0059] When the strap 6 is loosened, the exposed length of the strap 6 is sufficient to allow the worker's foot to pass through the gap between the strap 6 and the foot pedal 4, and the foot and foot pedal 4 can be fixed by the strap 6. In other words, the worker can pass through the gap between the strap 6 and the foot pedal 4 and fix his foot and foot pedal 4 by the strap 6.

[0060] Next, the structure of the pole climbing foot pedal of the present invention will be described in detail.

[0061] The fastening mechanism includes a first fastening body 2, a second fastening body 3, a sliding sleeve 5, and a connecting rod. The first fastening body 2 is fixedly connected to one end of the connecting rod. The sliding sleeve 5 is slidably sleeved on the connecting rod, and the second fastening body 3 is fixedly connected to the sliding sleeve 5. The first fastening body 2 and the second fastening body 3 are arranged opposite to each other. The sliding sleeve 5 is fixedly connected to the connecting rod by a fastening mechanism. It also includes a first anti-slip pad 8 disposed on the side of the first fastening body 2 near the second fastening body 3, and a second anti-slip pad 9 disposed on the side of the second fastening body near the first fastening body 2.

[0062] The first anti-slip pad 8 and the second anti-slip pad 9 make it easier to keep the feet firmly planted on the utility pole.

[0063] The relative distance between the second buckle 3 and the first buckle 2 can be adjusted by the sliding sleeve 5, so that the pole climbing foot pedal can be adapted to more sizes of utility poles.

[0064] The sliding sleeve 5 is slidably mounted on the connecting rod. When the sliding sleeve 5 slides to a certain position, the sliding sleeve 5 and the connecting rod can be fixed by the fastening mechanism to prevent the relative positions of the first buckle 2 and the second buckle 3 from changing.

[0065] Here, markings can be made on the connecting rod to indicate which types of utility poles correspond to the stop position of the sliding sleeve 5.

[0066] like Figure 8 , 9 As shown, specifically, the fastening mechanism includes a fastening bolt 10, a stop block 5a, and a nut 5b. Elongated holes are respectively provided through opposite side walls of the connecting rod, and a threaded hole is provided through one side wall of the sliding sleeve 5. The internal thread of the nut 5b is opposite in direction to the threaded hole. The fastening bolt 10 is threadedly connected to the threaded hole, and the fastening bolt 10 extends sequentially through the threaded hole and the two elongated holes into the interior of the sliding sleeve 5. The stop block 5a is fixedly connected to the inner side wall of the sliding sleeve 5, and the stop block 5a is positioned opposite the elongated hole away from the threaded hole. The nut 5b is threadedly connected to the end of the connecting rod away from the threaded hole, and the nut 5b abuts against the stop block 5a to restrict the rotation of the nut 5b.

[0067] Nut 5b can be selected in a shape that is not circular, and one side of the outer shape must be flat, such as hexagonal nut 5b or square nut 5b.

[0068] The internal thread of the nut 5b is opposite in direction to the threaded hole. When the fastening bolt 10 needs to be unscrewed, rotating the fastening bolt 10 in one direction moves it away from the sliding sleeve 5. Under the action of the stop block 5a, the nut 5b moves away from the connecting rod. Similarly, when the fastening bolt 10 rotates in the opposite direction, it moves towards the sliding sleeve 5. Under the action of the stop block 5a, the nut 5b moves towards the connecting rod. This secures the sliding sleeve 5 and the connecting rod. A limiting block can be provided at the end of the fastening bolt 10 away from the threaded hole to prevent the nut 5b from sliding out of the fastening bolt 10. In this way, the sliding sleeve 5 slides on the connecting rod, and the fastening bolt 10 slides within the elongated hole.

[0069] like Figure 2 As shown, in this embodiment, the first control mechanism includes a first motor 7b fixed on the inner sidewall of the safety box 7. The first motor 7b is electrically connected to the controller III. The axis of the first rotating shaft of the first motor 7b is parallel to the upper surface of the foot pedal 4, and the axis of the first rotating shaft of the first motor 7b is perpendicular to the line connecting the two safety boxes 7. The first rotating shaft is fixedly connected to one end of the strap 6, and the strap 6 is wrapped around the first rotating shaft.

[0070] The lower surface of the safety box 7 is not lower than the lower surface of the foot pedal 4. The upper surface of the safety box 7 can be flush with or lower than the upper surface of the foot pedal 4 (the surface that contacts the sole of the foot), or it can be approximately higher than the upper surface of the foot pedal 4. However, if it is approximately higher than the upper surface of the foot pedal 4, then the difference in distance between the upper surface of the safety box 7 and the upper surface of the foot pedal 4 is less than the thickness of a thumb. In this way, even if there is a gap between the strap 6 and the foot pedal 4 after the strap 6 is tightened, the worker's foot cannot pass through the gap.

[0071] The binding strap 6 is wound around the first rotating shaft. Rotating the first rotating shaft can unwind or rewind the binding strap 6. Unwinding the binding strap 6 simultaneously on both sides will loosen it, and rewinding it simultaneously will tighten it. The rotation direction of the first motor 7b is set according to the actual connection direction between the binding strap 6 and the first rotating shaft, and will not be elaborated here.

[0072] Example 2, based on Example 1, further includes a clamping mechanism disposed on the two long sidewalls opposite to the opening 7a, such as... Figure 3-7 As shown, the long sidewall of the opening 7a is recessed inward and a first groove 7c is provided. A clamping plate 7d is slidably disposed in the first groove 7c. The clamping plate 7d is mounted on both sides adjacent to the opening 7a with a driving mechanism that moves the clamping plate 7d toward or away from the opening 7a.

[0073] The two clamps 7d can hold the strap 6, reducing the tension of the strap 6 on the first motor 7b when using the pole climbing foot pedal.

[0074] The driving mechanism includes a second motor 7f, a roller 7g, and a mounting plate 7e. The second motor 7f is electrically connected to the controller III. The mounting plate 7e is fixedly connected to the side wall of the clamping plate 7d, and the second motor 7f is mounted on the mounting plate 7e. The axial direction of the second rotating shaft of the second motor 7f is parallel to the direction of the opening 7a of the opening 7a. The second rotating shaft passes through the mounting plate 7e and is fixedly connected to the roller 7g. The roller 7g contacts the side wall of the first groove 7c.

[0075] like Figure 7 As shown, two mounting plates can be provided along the opening direction, and the roller is provided between the two mounting plates. In this embodiment, the second motor is mounted on the upper mounting plate, and the second rotating shaft passes through the upper mounting plate and is fixedly connected to the roller. The second rotating shaft and the lower mounting plate are rotatably connected by bearings.

[0076] The roller 7g can be a cylindrical wheel, with its sidewall abutting against the sidewall of the first groove 7c. The materials of the cylindrical wheel and the sidewall of the first groove 7c can be set to maximize the friction between them. This minimizes the possibility of the cylindrical wheel sliding on the first groove 7c, allowing it to move relative to the first groove 7c only by rotating the shaft of the second motor 7f.

[0077] Example 3 also discloses a method of using a safety pole climbing foot pedal system, which includes:

[0078] Grounding wire status signal detection module I detects the status of the grounding wire and sends the detected status signal as a detection signal to grounding wire status signal receiving module II;

[0079] The grounding wire status signal receiving module II will receive the detection signal and transmit it to the controller III;

[0080] The controller III controls the first control mechanism to loosen or tighten the strap 6 based on the detection signal and the status information of the first control mechanism stored in the memory IV.

[0081] In this embodiment, the state information of the first control mechanism is specifically the state information of the first motor 7b. The state information of the first motor 7b includes an initial state and a rotational state. When the first motor 7b is in the initial state, the strap 6 is loosened; when the first motor 7b is in the rotational state, the strap 6 is tightened. The specific process by which the controller III controls the first control mechanism to perform the loosening or tightening operation of the strap 6 based on the detection signal and the state information of the first control mechanism stored in the memory IV is as follows:

[0082] S1. The status information of the first motor 7b before the grounding wire is connected is transmitted to the memory IV for storage. At the same time, the storage signal of the memory IV is transmitted to the controller III.

[0083] S2. Connect the grounding wire and detect it through the grounding wire status signal detection module I. Transmit the detection signal to the controller III through the grounding wire status signal receiving module II.

[0084] S3. When the detection signal is not hooked or poorly hooked and the status information of the first motor 7b is in the initial state, the controller III controls the first shaft of the first motor 7b to rotate so that the first motor 7b becomes rotating, thereby tightening the strap 6. Then, the status information of the first motor 7b is transmitted to the memory IV to replace the original status information of the first motor 7b stored in the memory IV.

[0085] When the detection signal is not hooked or poorly hooked, it means that the machine cannot work at this time. In this case, the strap 6 should be tightened. However, the strap 6 is initially in the loose state. Therefore, the first shaft needs to rotate (i.e., the strap 6 needs to be wound up). After the winding is completed, the new status information (rotation status) of the first motor 7b is transmitted to the memory IV, replacing the original initial state in the memory IV.

[0086] When the detection signal is not hooked or poorly hooked and the status information of the first motor 7b is in the rotating state, the controller III controls the first motor 7b to remain stationary, so that the strap 6 remains in the tightened state, and then transmits the status information of the first motor 7b to the memory IV to replace the original status information of the first motor 7b stored in the memory IV.

[0087] When the detection signal indicates that the device is not hooked or is not hooked properly, it means that the device cannot work at this time. In this case, the strap 6 should be tightened. Since the strap 6 is initially in the tightened state, the first rotating shaft does not need to rotate. Instead, the status information (rotation state) of the first motor 7b is transmitted to the memory IV, replacing the original rotation state in the memory IV. At this time, if the status information of the first motor 7b is not changed, the original state in the memory IV can also be left unchanged. This can be set according to the actual situation in the field.

[0088] When the detection signal is stable and the status information of the first motor 7b is in the initial state, the controller III controls the first motor 7b to remain stationary, so that the strap 6 remains loose, and then transmits the status information of the first motor 7b to the memory IV to replace the original status information of the first motor 7b stored in the memory IV.

[0089] When the detection signal indicates stable connection, it means that the machine can operate at this time. Therefore, the strap 6 should be loosened. Since the initial state of the strap 6 is the loosened state, the first shaft does not need to rotate. It only transmits the state information (initial state) of the first motor 7b to the memory IV, replacing the original initial state in the memory IV. Similarly, if the state information of the first motor 7b is not changed, the original state in the memory IV can also be left unchanged. This can be set according to the actual situation in the field.

[0090] When the detection signal indicates stable connection and the status information of the first motor 7b is in a rotating state, the controller III controls the first motor 7b to rotate back to its initial state, thereby releasing the strap 6. Then, the status information of the first motor 7b is transmitted to the memory IV to replace the original status information of the first motor 7b stored in the memory IV.

[0091] When the detection signal indicates that the connection is stable, it means that the machine can work at this time. In this case, the strap 6 should be loosened. However, the initial state of the strap 6 is the tightened state. Therefore, the first rotating shaft needs to rotate in the opposite direction (that is, the strap 6 needs to be unwound). After the unwinding is completed, the new state information (loose state) of the first motor 7b is transmitted to the memory IV, replacing the original rotation state in the memory IV.

[0092] In Example 4, based on Example 3, the controller III further controls the rotation of the second motor 7f according to the detection signal and the state information of the first control mechanism. When both second motors 7f are in the corresponding long-stop position, they clamp the strap 6 relative to the two clamping plates 7d. The state information of the first control mechanism is specifically the state information of the first motor 7b, which includes the initial state and the rotation state. The long-stop position refers to the position of the second motor 7f when the strap 6 is clamped relative to the two clamping plates 7d.

[0093] Specifically:

[0094] When the detection signal is not connected or poorly connected, and the status information of the first motor 7b is in the initial state, the controller III controls the second motor 7f to rotate, causing the clamping plate 7d to move away from the opening 7a. After the status information of the first motor 7b changes, the controller III controls the second motor 7f to rotate in the opposite direction, causing the clamping plate 7d to move closer to the opening 7a, so that the second motor 7f is in the long-term stop position.

[0095] When the detection signal is not hooked or poorly hooked, it means that the machine cannot work at this time. In this case, the strap 6 should be tightened. However, the strap 6 is initially in a loose state. Therefore, the first rotating shaft should rotate. At this time, the two clamps 7d should move away from each other to facilitate the first rotating shaft to perform a winding operation on the strap 6.

[0096] When the detection signal is not connected or poorly connected and the status information of the first motor 7b is in the rotating state, the controller III controls the second motor 7f to remain stationary, so that the second motor 7f is in the long-term stop position.

[0097] When the detection signal is not hooked or poorly hooked, it means that the machine cannot work at this time. In this case, the strap 6 should be tightened. Since the strap 6 is initially in a tightened state, the first rotating shaft does not need to rotate to wind up the strap 6. At this time, the two clamps 7d do not need to move away from each other.

[0098] When the detection signal is stable and the status information of the first motor 7b is in the initial state, the controller III controls the second motor 7f to remain stationary, so that the second motor 7f is in the long-stop position.

[0099] When the detection signal indicates that the connection is stable, it means that the machine can work at this time. In this case, the strap 6 should be loosened. Since the first state of the strap 6 is the loosened state, the first rotating shaft does not need to rotate to unwind the strap 6. At this time, the two clamps 7d do not need to move away from each other.

[0100] When the detection signal indicates stable connection and the status information of the first motor 7b is in a rotating state, the controller III controls the second motor 7f to rotate, causing the clamping plate 7d to move away from the opening 7a. After the status information of the first motor 7b changes, the controller III controls the second motor 7f to rotate in the opposite direction, causing the clamping plate 7d to move closer to the opening 7a, ultimately placing the second motor 7f in a stationary position.

[0101] When the detection signal indicates that the connection is stable, it means that the machine can work. In this case, the strap 6 should be loosened. However, the strap 6 is initially in a tightened state. Therefore, the first rotating shaft should rotate in the opposite direction.

The state information of the first motor includes an initial state and a rotational state. When the first motor is in the initial state, the strap is loosened; when the first motor is in the rotational state, the strap is tightened. The specific process by which the controller controls the first control mechanism to perform the loosening or tightening operation of the strap based on the detection signal and the state information of the first control mechanism stored in the memory is as follows: S1. The status information of the first motor before the grounding wire is connected is transmitted to the memory for storage, and at the same time, the storage signal of the memory is transmitted to the controller. S2. Connect the grounding wire and detect it through the grounding wire status signal detection module. Transmit the detection signal to the controller through the grounding wire status signal receiving module. S3. When the detection signal is not hooked or poorly hooked and the status information of the first motor is in the initial state, the controller controls the first shaft of the first motor to rotate so that the first motor becomes rotating, thereby tightening the strap. Then, the status information of the first motor is transmitted to the memory to replace the original status information of the first motor stored in the memory. When the detection signal is not hooked or poorly hooked and the status information of the first motor is in the rotating state, the controller controls the first motor to remain stationary, so that the strap remains in a tightened state, and then transmits the status information of the first motor to the memory to replace the original status information of the first motor stored in the memory. When the detection signal indicates stable connection and the status information of the first motor is in the initial state, the controller controls the first motor to remain stationary, keeping the strap loose, and then transmits the status information of the first motor to the memory to replace the original status information of the first motor stored in the memory. When the detection signal indicates stable connection and the status information of the first motor is in a rotating state, the controller controls the first motor to rotate back to its initial state, thereby loosening the strap. Then, the status information of the first motor is transmitted to the memory to replace the original status information of the first motor stored in the memory.

10. The method of using a safety pole-climbing foot pedal system according to claim 8, characterized in that, The controller also controls the rotation of the second motor based on the detection signal and the status information of the first control mechanism. When both second motors are rotating and in their corresponding long-stop positions, the two opposing clamps will clamp the straps. The status information of the first control mechanism is specifically the status information of the first motor, which includes an initial state and a rotational state. When the detection signal is not connected or poorly connected, and the status information of the first motor is in the initial state, the controller controls the second motor to rotate, causing the clamping plate to move away from the opening. After the status information of the first motor changes, the controller controls the second motor to rotate in the opposite direction, causing the clamping plate to move closer to the opening, and finally the second motor is in the long-term stop position. When the detection signal is not connected or poorly connected and the status information of the first motor is rotating, the controller controls the second motor to remain stationary, so that the second motor is in a long-term stop position; When the detection signal is stable and the status information of the first motor is in the initial state, the controller controls the second motor to remain stationary, so that the second motor is in a long-term stop position; When the detection signal indicates stable connection and the first motor's status information indicates rotation, the controller controls the second motor to rotate, causing the clamping plate to move away from the opening. After the status information of the first motor changes, the controller controls the second motor to rotate in the opposite direction, causing the clamping plate to move closer to the opening, ultimately placing the second motor in a stationary position.
