Description

Technical Field

[0001] This invention relates to the field of electric winch technology, and in particular to an electric winch system for fire trucks and its usage method. Background Technology

[0002] An electric winch mainly consists of a motor, drive shaft, planetary gear reducer, and drum. The planetary gear reducer connects the motor and drum, allowing the rope wound on the drum to generate significant traction, thus achieving the winch's traction function. In addition to its traction function, an electric winch often includes a clutch mechanism within the planetary gear reducer to disconnect the power connection between the motor and the drum.

[0003] To enhance rescue capabilities, existing fire trucks typically have an electric winch installed at the front. This allows fire trucks to perform self-rescue and rescue operations in harsh environments such as snow, swamps, deserts, beaches, and muddy mountain roads. It also enables them to clear obstacles, tow items, and install equipment under other conditions. Currently, after each use, the electric winch requires the tow rope to be unwound and rewound to ensure even winding and layering. Furthermore, operators must clean the tow rope during rewinding to prevent dust or water stains from reducing its surface strength. This manual rewinding and cleaning method is inefficient, and manual observation of the winding status is relatively rough. Therefore, this paper proposes a fire truck electric winch system and its operating method. Summary of the Invention

[0004] The purpose of this invention is to solve the problem in the prior art that the towing rope needs to be manually wound up throughout the entire process, and to propose an electric winch system for fire trucks and a method of using it.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fire truck electric winch system includes a mounting box, an electric winch mechanism is fixedly installed at the bottom of the mounting box, and a winding mechanism for use in conjunction with the electric winch mechanism is also provided at the bottom of the mounting box.

[0007] The winding mechanism includes a housing fixedly mounted on one side of the electric winch mechanism. A partition plate is fixedly mounted inside the lower part of the housing, dividing the interior of the housing into a winding cleaning chamber and a power chamber from top to bottom. A sliding plate is slidably mounted at the bottom of the winding cleaning chamber and above the partition plate. A sliding shell is slidably mounted inside the upper part of the winding cleaning chamber. Two rectangular limiting blocks are symmetrically fixed between the sliding plate and the sliding shell. An adjusting ring is rotatably mounted inside the rectangular limiting block. An annular groove is formed on the outer side of the middle part of the adjusting ring. A ring of driven teeth is fixedly mounted inside the annular groove. Multiple connecting rods are fixedly mounted between the two adjusting rings. Multiple sets of cleaning brushes are fixedly mounted in the middle of the connecting rods.

[0008] The winding mechanism also includes a cleaning component disposed inside the sliding shell. The cleaning component includes a first drive motor fixedly disposed in the middle of the upper end of the sliding shell and a rotating shaft rotatably disposed inside the sliding shell. The upper end of the rotating shaft is fixedly connected to the output end of the first drive motor. An active half-bevel gear is fixedly disposed in the middle of the rotating shaft. A fan blade is fixedly disposed at the lower end of the rotating shaft and between two rectangular limit blocks.

[0009] The sliding shell also has two driven shafts symmetrically rotating inside. A driven bevel gear is fixed at one end of the driven shaft near the driving half bevel gear. The driving half bevel gear can mesh with the two driven bevel gears. A drive gear is also fixed in the middle of the driven shaft. The drive gear can mesh with the driven tooth block inside the lower annular groove. An arc-shaped groove is opened at the upper end of the rectangular limiting block to facilitate the rotation of the drive gear.

[0010] The above technical solution further includes:

[0011] The inner side of the power cavity is also provided with a drive assembly for driving the sliding plate to slide. The drive assembly includes a second drive motor fixedly installed on the outer side of the housing and a drive screw rotatably installed on the inner side of the power cavity. One end of the drive screw is fixedly connected to the output end of the second drive motor. The middle part of the drive screw is provided with a threaded seat through a threaded connection. A push rod is fixedly installed at the lower middle part of the sliding plate. A rectangular groove is opened in the middle part of the partition plate to facilitate the sliding of the push rod. The upper end of the threaded seat is provided with a mounting groove for use with the push rod. The lower middle part of the push rod is provided with a positioning hole. The side wall of the mounting groove is provided with a mounting hole for use with a positioning pin.

[0012] The winding mechanism also includes a detection component located on one side of the housing. The detection component includes a strip-shaped limiting block fixedly located on the inner side of the lower end of the housing. A T-shaped sliding block is slidably provided inside the strip-shaped limiting block. A drive rod is fixedly provided between the T-shaped sliding block and the threaded seat. An eddy current sensor is fixedly provided inside the T-shaped sliding block. The eddy current sensor is inclined as a whole.

[0013] The above technical solution further includes:

[0014] The electric winch mechanism consists of a winch drum, a winch motor, and a gearbox. A traction rope is wound around the middle of the winch drum. A cylindrical inlet is provided in the middle of the adjusting ring to facilitate the passage of the traction rope. The cylindrical inlet is also provided with a wear-resistant brass bushing.

[0015] The above technical solution further includes:

[0016] The rectangular limiting block has two symmetrical circular through holes in its center, and the interior of the rectangular limiting block has a rotating cavity to facilitate the rotation of the adjusting ring.

[0017] The above technical solution further includes:

[0018] The upper interior of the housing is symmetrically provided with two limiting strips to restrict the sliding of the sliding shell.

[0019] The above technical solution further includes:

[0020] The central axis of the eddy current sensor is perpendicular to the central axis of the winch drum.

[0021] The above technical solution further includes:

[0022] The partition plate has a rectangular discharge trough in the middle to facilitate the falling of dust, and the sliding plate also has a discharge port in the middle to facilitate the falling of dust.

[0023] The above technical solution further includes:

[0024] A roller rope guide for use with a traction rope is fixedly provided on the outer middle of the shell. The roller rope guide includes a rectangular plate fixed on the outer side of the shell. Two horizontal rope guide rods are arranged horizontally on one side of the inner side of the rectangular plate, and two vertical rope guide rods are arranged vertically on the other side of the inner side of the rectangular plate.

[0025] The above technical solution further includes:

[0026] The housing has a rectangular inlet / outlet slot in the middle to facilitate the entry and exit of the traction rope, and an installation window is provided on one side of the lower end of the housing to facilitate the insertion of the positioning pin.

[0027] The above technical solution further includes:

[0028] The mounting box is also equipped with an internal data controller. The signal output terminal of the eddy current sensor is electrically connected to the signal input terminal of the internal data controller. The signal output terminal of the internal data controller is electrically connected to the controllers of the first drive motor, the second drive motor, and the winch motor.

[0029] The above technical solution further includes:

[0030] Its characteristic is that it includes the following steps:

[0031] a. Before the traction rope is wound up, the operator observes through the installation window whether the positioning pin is inserted. If the positioning pin is not inserted, the threaded seat and the push rod are not fixedly connected by the positioning pin, that is, the movement of the threaded seat cannot drive the sliding plate.

[0032] b. To check the number of winding layers in the middle of the winch drum, the internal data controller sends a control signal to make the second drive motor work, which in turn makes the threaded seat move in the middle of the drive screw, further driving the eddy current sensor to move below the winch drum. At this time, a plane rectangular coordinate system can be established inside the internal data controller, with one end of the drive screw as the origin of the X-axis coordinate, the path data of the threaded seat movement as the coordinate of each point on the X-axis, and the measurement data of the eddy current sensor as the Y-axis, that is, the data of the distance from the end of the eddy current sensor to the middle of the winch drum as the coordinate of each point on the Y-axis. After recording and processing by the internal data controller, the winding data of the traction rope in the middle of the winch drum can be obtained. By processing the data by the internal data controller, it can be determined how to control the second drive motor to work in the next step.

[0033] c. Winding of the traction rope: The internal data controller sends control signals to make the first drive motor, the second drive motor and the winch motor work. Before the traction rope is wound, the operator inserts the positioning pin so that the threaded seat and the push rod are fixedly connected by the positioning pin. The operation of the winch motor can make the traction rope wind in the middle of the winch drum. The second drive motor guides the traction rope to the winding position in the middle of the winch drum. The operation of the first drive motor drives the cleaning component to work, thereby cleaning the traction rope.

[0034] d. Inspection after the traction rope is wound: After the traction rope is wound, the internal data controller sends a control signal to make the second drive motor work, which in turn makes the winding mechanism reset. The operator takes out the positioning pin again, that is, the winding condition in the middle of the winch drum is checked again by moving the eddy current sensor back and forth. After comparing the relevant data in the internal data controller with the specifications, the threaded seat is reset, which facilitates the use of the electric winch mechanism next time.

[0035] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0036] In this invention, the driving component first drives the detection component to work, and the eddy current sensor can detect the winding of the traction rope in the middle of the winch drum and transmit the data to the internal data controller, thereby controlling the operation of the second drive motor in the next process. This makes the entire winding process unnecessary for the operator to observe the winch drum inside the installation box, greatly improving the winding efficiency and the winding quality of the traction rope.

[0037] At the same time, the drive component can drive the winding mechanism to work, which in turn causes the sliding plate, sliding shell and rectangular limit block to slide back and forth inside the shell. In conjunction with the work of the winch motor and roller rope guide, the traction rope can be evenly and orderly wound around the middle of the winch drum. The whole process does not require the operator to hold the other end of the traction rope for rewinding, which greatly reduces the workload of the operator. Furthermore, the cooperation between the drive component and the winding mechanism can also improve the rewinding efficiency.

[0038] Throughout the process, the traction rope can be cleaned by the cleaning components inside the housing. The first drive motor drives the cleaning brushes in the middle of multiple connecting rods to repeatedly clean the outer surface of the traction rope. The fan blades can also blow the swept dust out of the housing, greatly increasing cleaning efficiency, preventing dust from adhering and affecting the traction rope, and ensuring the service life of the traction rope.

Detailed Implementation

[0051] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0052] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0053] like Figure 1-11 As shown, the present invention proposes a fire truck electric winch system and its usage method, including a mounting box 1, an electric winch mechanism 2 fixedly provided at the bottom of the mounting box 1, and a winding mechanism 3 for use in conjunction with the electric winch mechanism 2 at the bottom of the mounting box 1.

[0054] The winding mechanism 3 includes a housing 301 fixedly mounted on one side of the electric winch mechanism 2. A partition plate 302 is fixedly mounted on the lower part of the housing 301. The partition plate 302 divides the interior of the housing 301 into a winding cleaning chamber and a power chamber from top to bottom. A sliding plate 303 is slidably mounted at the bottom of the winding cleaning chamber and at the upper end of the partition plate 302. A sliding shell 304 is slidably mounted on the upper part of the interior of the winding cleaning chamber. Two rectangular limiting blocks 305 are symmetrically fixed between the sliding plate 303 and the sliding shell 304. An adjusting ring 306 is rotatably mounted inside the rectangular limiting block 305. An annular groove 3061 is opened on the outer side of the middle part of the adjusting ring 306. A ring of driven toothed blocks 3062 is fixedly mounted inside the annular groove 3061. Multiple connecting rods 307 are fixedly mounted between the two adjusting rings 306. Multiple sets of cleaning brushes 308 are fixedly mounted in the middle of the connecting rods 307.

[0055] The winding mechanism 3 also includes a cleaning component 5 disposed inside the sliding shell 304. The cleaning component 5 includes a first drive motor 501 fixedly disposed in the middle of the upper end of the sliding shell 304 and a rotating shaft 502 rotatably disposed inside the sliding shell 304. The upper end of the rotating shaft 502 is fixedly connected to the output end of the first drive motor 501. An active half-bevel gear 503 is fixedly disposed in the middle of the rotating shaft 502. A fan blade 504 is fixedly disposed at the lower end of the rotating shaft 502 and between two rectangular limit blocks 305.

[0056] The sliding shell 304 also has two driven shafts 505 symmetrically rotatably mounted inside. A driven bevel gear 506 is fixedly mounted at one end of the driven shaft 505 near the driving half bevel gear 503. The driving half bevel gear 503 can mesh with the two driven bevel gears 506. A drive gear 507 is also fixedly mounted in the middle of the driven shaft 505. The drive gear 507 can mesh with the driven tooth block 3062 inside the lower annular groove 3061. An arc-shaped groove is opened at the upper end of the rectangular limiting block 305 to facilitate the rotation of the drive gear 507.

[0057] The cleaning of the traction rope 203 triggers a control signal from the internal data controller, causing the first drive motor 501 to operate (see [reference]). Figure 4 , Figure 6 and Figure 11 The first drive motor 501 can drive the rotating shaft 502 to rotate, and the rotation of the rotating shaft 502 can drive the active half bevel gear 503 and the fan blades 504 to rotate in the plane.

[0058] The rotation of the driving half-bevel gear 503 can drive the two driven bevel gears 506 meshing with it to rotate. That is, when the driving half-bevel gear 503 meshes with the driven bevel gear 506 on the left, it can drive the driven bevel gear 506 on the left to rotate in the forward direction. At this time, the driving half-bevel gear 503 does not mesh with the driven bevel gear 506 on the right. As the driving half-bevel gear 503 continues to rotate, the driving half-bevel gear 503 will not mesh with the driven bevel gear 506 on the left, but will mesh with the driven bevel gear 506 on the right, thereby driving the driving gear 507 on the right to rotate in the reverse direction.

[0059] When the drive gear 507 on the left rotates in the forward direction, it can drive the driven gear block 3062 below to move, which further causes the adjusting ring 306 to rotate. At the same time, because the two adjusting rings 306 are fixedly connected by multiple connecting rods 307, the two adjusting rings 306 and the multiple connecting rods 307 rotate in the forward direction in the vertical plane. At this time, the cleaning brush 308 can clean the traction rope 203.

[0060] When the drive gear 507 on the right rotates in the opposite direction, it can drive the adjusting ring 306 below to rotate in the opposite direction, that is, drive the two adjusting rings 306 and multiple connecting rods 307 to rotate in the opposite direction in the vertical plane, thereby cleaning the traction rope 203.

[0061] The rotation of the active half-bevel gear 503 drives the two adjusting rings 306 and multiple connecting rods 307 to rotate in the forward and reverse directions in the vertical plane, thereby improving the cleaning effect. Furthermore, the rotation of the fan blades 504 can accelerate the discharge of swept dust, that is, accelerate the dust to pass through the discharge port and the rectangular discharge chute.

[0062] The two adjusting rings 306 and multiple connecting rods 307 rotate in the positive direction in the vertical plane.

[0063] Furthermore, a drive assembly 6 for driving the sliding plate 303 to slide is provided on one side of the power cavity. The drive assembly 6 includes a second drive motor 601 fixedly installed on one side of the outer side of the housing 301 and a drive screw 602 rotatably installed on one side of the power cavity. One end of the drive screw 602 is fixedly connected to the output end of the second drive motor 601. A threaded seat 603 is provided in the middle of the drive screw 602 through a threaded connection. A push rod 604 is fixedly installed in the middle of the lower end of the sliding plate 303. A rectangular groove is opened in the middle of the partition plate 302 to facilitate the sliding of the push rod 604. An installation groove 605 for use with the push rod 604 is opened at the upper end of the threaded seat 603. A positioning hole is opened in the middle of the lower end of the push rod 604. An installation hole for use with a positioning pin is opened on the side wall of the installation groove 605.

[0064] The winding mechanism 3 also includes a detection component 7 located on one side of the housing 301. The detection component 7 includes a strip-shaped limiting block 701 fixedly located on the inner side of the lower end of the housing 301. A T-shaped sliding block 702 is slidably provided inside the strip-shaped limiting block 701. A drive rod 703 is fixedly provided between the T-shaped sliding block 702 and the threaded seat 603. An eddy current sensor 704 is fixedly provided inside the T-shaped sliding block 702. The eddy current sensor 704 is inclined as a whole.

[0065] To check the number of winding layers in the middle of the winch drum 201, first check whether the threaded seat 603 and the push rod 604 are fixedly connected by a positioning pin. After confirming that the positioning pin is not inserted, start the second drive motor 601. The second drive motor 601 works and drives the drive screw 602 to rotate. The rotation of the drive screw 602 can drive the threaded seat 603 to slide at the bottom of the power chamber. By controlling the forward and reverse rotation of the second drive motor 601, the reciprocating movement of the threaded seat 603 can be realized.

[0066] During the movement of the threaded seat 603, the T-shaped sliding block 702 can be driven to slide inside the strip-shaped limiting block 701 by the drive rod 703, thereby realizing the reciprocating motion of the T-shaped sliding block 702. Since the eddy current sensor 704 is inclinedly set inside the T-shaped sliding block 702, and the central axis of the eddy current sensor 704 is perpendicular to the central axis of the winch drum 201, the winding condition in the middle of the winch drum 201 can be detected by the eddy current sensor 704. If the data detected each time is ΔY, the internal data controller determines the magnitude of the data Y1, Y2, Y3... detected each time to know the winding condition. If the actual winding situation in the middle of the drum 201 is Y1 > Y2, it means that the number of winding layers in the middle of the winch drum 201 at Y1 is greater than that at Y2. When winding, the winding starts from the detected Y2. In order to determine the data position of ΔY, the initial position of the thread seat 603 can be X0, i.e., the origin of the coordinates, and the distance of the thread seat 603 from the initial state can be ΔX. Then the winding data of each point in the middle of the winch drum 201 will have a relative coordinate X,Y. The actual winding situation of each point is determined by the internal data controller, and the position of the thread seat 603 is controlled in the next winding step, thereby controlling the winding of the traction rope 203.

[0067] After the winding condition of the winch drum 201 is checked, the threaded seat 603 is reset. At this time, the operator can use the positioning pin to fix the threaded seat 603 and the push rod 604. The internal data controller can control the rotation of the second drive motor 601 by detecting relevant data, thereby moving the sliding plate 303, the sliding shell 304 and the rectangular limit block 305 to a suitable position inside the shell 301. Then, the internal data controller controls the winch motor 202 to work, thereby realizing the automatic winding of the traction rope 203.

[0068] Furthermore, the electric winch mechanism 2 consists of a winch drum 201, a winch motor 202, and a gearbox 204. The winch drum 201 has a traction rope 203 wound around its middle section. The adjusting ring 306 has a cylindrical inlet in its middle section to facilitate the passage of the traction rope 203. The cylindrical inlet is also equipped with a wear-resistant brass bushing. After the traction rope 203 passes through the adjusting ring 306, it will be limited by the two adjusting rings 306, so that the traction rope 203 is in a horizontal state, which facilitates the subsequent automatic winding work.

[0069] Furthermore, two circular through holes are symmetrically opened in the middle of the rectangular limiting block 305, and a rotating cavity is opened inside the rectangular limiting block 305 to facilitate the rotation of the adjusting ring 306.

[0070] Furthermore, two limiting strips are symmetrically provided on the upper part of the interior of the housing 301 to facilitate the restriction of the sliding of the sliding housing 304.

[0071] Furthermore, a rectangular material discharge groove is provided in the middle of the partition plate 302 to facilitate the falling of dust, and a material discharge port is also provided in the middle of the sliding plate 303 to facilitate the falling of dust.

[0072] Furthermore, a roller rope guide 4 for use with the traction rope 203 is fixedly provided on the outer middle of the housing 301. The roller rope guide 4 includes a rectangular plate fixed on the outer side of the housing 301. Two horizontal rope guide rods are arranged horizontally on one side of the inner side of the rectangular plate, and two vertical rope guide rods are arranged vertically on the other side of the inner side of the rectangular plate.

[0073] Furthermore, a rectangular inlet / outlet groove is provided in the middle of the housing 301 to facilitate the entry and exit of the traction rope 203, and an installation window is also provided on one side of the lower end of the housing 301 to facilitate the insertion of the positioning pin.

[0074] Furthermore, the installation box 1 is also equipped with an internal data controller. The signal output terminal of the eddy current sensor 704 is electrically connected to the signal input terminal of the internal data controller. The signal output terminal of the internal data controller is electrically connected to the controllers of the first drive motor 501, the second drive motor 601, and the winch motor 202.

[0075] Furthermore, the following steps are included:

[0076] a. Before the traction rope 203 is wound up, the operator observes whether the positioning pin is inserted through the installation window. Ensure that the positioning pin is not inserted. At this time, the threaded seat 603 and the push rod 604 are not fixedly connected by the positioning pin and are in the initial state. That is, the movement of the threaded seat 603 cannot drive the sliding plate 303.

[0077] b. Checking the number of winding layers in the middle of the winch drum 201: The internal data controller sends a control signal to make the second drive motor 601 work, which in turn makes the threaded seat 603 move in the middle of the drive screw 602, further driving the eddy current sensor 704 to move below the winch drum 201. At this time, a plane rectangular coordinate system can be established inside the internal data controller. The end of the drive screw 602 that is close to the second drive motor 601 is the origin of the X-axis coordinate system, the path data of the threaded seat 603 is the coordinate of each point on the X-axis, and the measurement data of the eddy current sensor 704 is the Y-axis, that is, the data of the distance between the end of the eddy current sensor 704 and the middle of the winch drum 201 is the coordinate of each point on the Y-axis. After recording and processing by the internal data controller, the winding data of the traction rope 203 in the middle of the winch drum 201 can be obtained. By processing the data by the internal data controller, it can be determined how to control the second drive motor 601 to work in the next step.

[0078] c. Winding of the traction rope 203: The internal data controller sends a control signal to make the first drive motor 501, the second drive motor 601, and the winch motor 202 work. Before the traction rope 203 winds, the operator inserts a positioning pin so that the threaded seat 603 and the push rod 604 are fixedly connected by the positioning pin. The operation of the winch motor 202 enables the traction rope 203 to wind in the middle of the winch drum 201. The second drive motor 601 guides the traction rope 203 to the winding position in the middle of the winch drum 201. The operation of the first drive motor 501 drives the cleaning component 5 to work, thereby cleaning the traction rope 203.

[0079] d. Inspection after the traction rope 203 is wound: After the traction rope 203 is wound, the internal data controller sends a control signal to make the second drive motor 601 work, which in turn makes the winding mechanism 3 reset, that is, the push rod 604 reset. The operator takes out the positioning pin again, that is, the winding condition of the middle part of the winch drum 201 is checked again by the back and forth movement of the eddy current sensor 704. After comparing the relevant data in the internal data controller with the specifications, the threaded seat 603 is reset, which facilitates the next use of the electric winch mechanism 2.

[0080] In this embodiment, the eddy current sensor 704 can detect the actual distance between the middle part of the winch drum 201 and the head of the eddy current sensor 704. Through the cooperation of the detection component 7 and the drive component 6, the eddy current sensor 704 can detect the winding situation at any point in the middle of the winch drum 201. This is better than traditional manual observation and can directly obtain relevant data. Furthermore, the detected data can also control the position of the second drive motor 601 during automatic winding, thereby improving the quality of automatic winding.

[0081] Simultaneously, through the cooperation of the cleaning component 5 and the drive component 6, the traction rope 203 can be cleaned synchronously during winding. The multiple sets of cleaning brushes 308 that rotate continuously in both directions can clean the traction rope 203 to the maximum extent and blow away the cleaned dust, thus improving the cleaning effect. Moreover, when the threaded seat 603 and the push rod 604 are fixedly connected by the positioning pin, the winding position of the traction rope 203 can be adjusted.

The signal output terminal of the internal data controller is electrically connected to the controllers of the first drive motor (501), the second drive motor (601), and the winch motor (202).

9. The method of using a fire truck electric winch system according to claim 1, characterized in that, Includes the following steps: a. Before the traction rope (203) is wound up, the operator observes whether the positioning pin is inserted through the installation window to ensure that the positioning pin is not inserted. At this time, the threaded seat (603) and the push rod (604) are not fixedly connected by the positioning pin (in the initial state), that is, the movement of the threaded seat (603) cannot drive the sliding plate (303). b. Checking the number of winding layers in the middle of the winch drum (201): The internal data controller sends a control signal to make the second drive motor (601) work, which in turn causes the threaded seat (603) to move in the middle of the drive screw (602), further driving the eddy current sensor (704) to move below the winch drum (201). At this time, a plane rectangular coordinate system can be established inside the internal data controller, with one end of the drive screw (602) (the end closer to the second drive motor (601)) as the X-axis. The origin of the target, the path data of the threaded seat (603) is the coordinate of each point on the X-axis, and the measurement data of the eddy current sensor (704) is the Y-axis, that is, the data of the distance from the end of the eddy current sensor (704) to the middle of the winch drum (201) is the coordinate of each point on the Y-axis. After the internal data controller records and processes the data, the winding data of the traction rope (203) in the middle of the winch drum (201) can be obtained. After the internal data controller processes the data, it can be determined how to control the second drive motor (601) to work in the next step. c. Winding of the traction rope (203): The internal data controller sends a control signal to make the first drive motor (501), the second drive motor (601), and the winch motor (202) work. Before the traction rope (203) winds, the operator inserts the positioning pin so that the threaded seat (603) and the push rod (604) are fixedly connected by the positioning pin. The operation of the winch motor (202) enables the traction rope (203) to wind in the middle of the winch drum (201). The second drive motor (601) guides the traction rope (203) to the winding position in the middle of the winch drum (201). The operation of the first drive motor (501) drives the cleaning component (5) to work, thereby cleaning the traction rope (203). d. Inspection after the traction rope (203) is wound. After the traction rope (203) is wound, the internal data controller sends a control signal to make the second drive motor (601) work, which in turn makes the winding mechanism (3) reset (i.e. the push rod (604) reset). The operator takes out the positioning pin again, that is, checks the winding situation in the middle of the winch drum (201) again by moving the eddy current sensor (704) back and forth. After comparing the relevant data in the internal data controller with the specifications, the thread seat (603) is reset, which facilitates the use of the electric winch mechanism (2) next time.
