Description

A logging device with in-well detachment mechanism Technical Field

[0001] This invention relates to the field of logging equipment technology, and in particular to a logging equipment in-well unblocking device. Background Technology

[0002] A vertical shaft is a well-shaped pipe with upright walls. Sometimes, it's necessary to probe the shaft, requiring logging equipment. Existing logging equipment typically uses a traction cable to pull and transmit data when entering the shaft. However, during probes inside the shaft, collapses can occur, burying the logging equipment beneath. This can cause the equipment to become stuck or even jammed when trying to move upwards, leading to damage or even irretrievable loss. To address these technical problems, this invention designs a logging equipment unblocking device. When a collapse occurs, it allows for reverse drilling (from bottom to top), enabling the logging equipment to be retrieved smoothly without damage or irretrievable loss. Summary of the Invention

[0003] This invention provides a well logging device that can be unjammed in the well to solve the problem that when a collapse occurs in the well, the well logging device may be jammed or even stuck by the collapsed soil, preventing it from moving upwards, causing damage to the well logging device, or even making it impossible to remove.

[0004] The technical problem solved by this invention is achieved by the following technical solution:

[0005] A logging device with an in-well detachment mechanism, comprising:

[0006] The logging device itself;

[0007] A traction cable, which is connected to the logging device body;

[0008] A tapered drill bit is located at the top of the logging device body and is rotatably connected to the logging device body. The outer contour dimension of the tapered drill bit is larger than the outer contour dimension of the logging device body.

[0009] A rotary drive mechanism is installed on the top of the logging device body and located below the conical drill bit. The rotary drive mechanism is connected to the conical drill bit and is used to drive the conical drill bit to rotate.

[0010] A downward shoveling mechanism is located below the conical drill bit and connected to the logging device body. The downward shoveling mechanism can retract and extend, and the outer contour dimension of the downward shoveling mechanism after retraction is less than or equal to the outer contour dimension of the conical drill bit.

[0011] A climbing mechanism is located below the downward shoveling mechanism and connected to the logging device body. The climbing mechanism is used to drive the logging device body to climb in the well.

[0012] Furthermore, the well logging device's in-well unsticking device also includes a spiral conveying mechanism located below the conical drill bit and above the climbing mechanism. The spiral conveying mechanism includes a spiral conveying sleeve and a first rotary drive assembly. The spiral conveying sleeve is fitted outside the well logging device body and can rotate relative to the well logging device body. The first rotary drive assembly is mounted on the well logging device body and connected to the spiral conveying sleeve. The rotation direction of the spiral conveying sleeve is opposite to the rotation direction of the conical drill bit. The conveying direction of the spiral conveying sleeve is from top to bottom.

[0013] Furthermore, the conical drill bit has a hollow structure with both ends open, and a support column and a conical support head are connected sequentially in the middle of the top of the logging device body, with the conical drill bit fitted onto the conical support head.

[0014] Furthermore, the rotary drive mechanism includes a rotary drive motor, a drive gear, and an internal gear ring. The port of the large end of the tapered drill bit is provided with an internal gear ring. The rotary drive motor is mounted on the body of the logging device. The drive gear is mounted on the output shaft of the rotary drive motor, and the drive gear meshes with the internal gear ring.

[0015] Furthermore, the downward shoveling mechanism includes a downward shoveling body, and the number of the downward shoveling bodies is at least three, with the plurality of downward shoveling bodies evenly distributed along the outer circumference of the logging device body;

[0016] For each of the downward shovel bodies: the downward shovel body includes a first retraction and expansion assembly, a shovel plate, a translation seat, a linear motion drive assembly, and a first support seat. The inner side of the first support seat is connected to the logging device body through the first retraction and expansion assembly. The translation seat is movably mounted on the first support seat. The first support seat is connected to the translation seat through the linear motion drive assembly. The linear motion drive assembly drives the translation seat to move up and down relative to the first support seat. There are multiple shovel plates, which are arranged horizontally and vertically side by side on the outer side of the translation seat and are rotatably connected to the translation seat. When the translation seat moves upward relative to the first support seat, the shovel plate closes relative to the translation seat. When the translation seat moves downward relative to the first support seat, the shovel plate opens relative to the translation seat, and the opening angle of the shovel plate relative to the translation seat is 15°-90°.

[0017] Furthermore, the first retractable and deployable assembly includes a support arm, a connecting rod, and a first eccentric motor. The support arm is provided with a strip-shaped window, and one end of the connecting rod is provided with a first oval hole. The connecting rod is located inside the strip-shaped window.

[0018] One end of the support arm is rotatably connected to the body of the logging device, forming a first hinge point; the other end of the support arm is rotatably connected to the first support base, forming a second hinge point; one end of the connecting rod is rotatably connected to the body of the logging device, forming a third hinge point; the other end of the connecting rod is rotatably connected to the first support base, forming a fourth hinge point; the first hinge point, the second hinge point, the third hinge point, and the fourth hinge point form a parallelogram linkage mechanism.

[0019] The first eccentric motor is mounted on the support arm, and the first eccentric shaft of the first eccentric motor is inserted into the first oval hole.

[0020] Furthermore, the linear motion drive assembly includes a second eccentric motor, a first slider, a second slider, and a transition gear. The second eccentric motor is mounted on the support arm, and the first slider is movably mounted on the support arm. One end of the first slider is provided with a second oblong hole, and the other end is provided with a first rack. The second eccentric shaft of the second eccentric motor is inserted into the second oblong hole.

[0021] The transition gear is rotatably mounted on the support arm, the first rack meshes with the transition gear, the translation seat is movably mounted on the first support seat via the second slider, and the second slider is provided with a second rack; when the first retraction and expansion assembly drives the first support seat to retract, the transition gear meshes with the second rack, and when the first retraction and expansion assembly drives the first support seat to expand, the transition gear disengages from the second rack.

[0022] Furthermore, the end of the shovel plate is provided with a limiting protrusion. When the shovel plate is opened relative to the translation seat until the limiting protrusion abuts against the translation seat, the shovel plate stops rotating relative to the translation seat.

[0023] Furthermore, the climbing mechanism includes a climbing body, and the number of climbing bodies is at least three, with multiple climbing bodies evenly distributed along the outer circumference of the logging device body;

[0024] For each of the climbing bodies: the climbing body includes a second retractable / deployable assembly, a second support base, a second rotary drive assembly, and tracks. The inner side of the second support base is connected to the logging device body through the second retractable / deployable assembly. There are multiple tracks, which are arranged side by side at equal intervals on the outer side of the second support base and are rotatable relative to the second support base. The number of second rotary drive assemblies is the same as the number of tracks and their positions are opposite. The second rotary drive assemblies are mounted on the second support base, and multiple second rotary drive assemblies are respectively connected to multiple tracks.

[0025] Furthermore, the second rotary drive assembly includes a drive motor, a worm, a worm wheel, and a drive gear. The conveying surface of the track is provided with a plurality of toothed grooves at equal intervals. The drive motor is mounted on the second support base. The output shaft of the drive motor is connected to the worm. The worm wheel is connected to the drive gear as a whole and is rotatably mounted on the second support base. The worm meshes with the worm wheel, and the drive gear meshes with the toothed grooves.

[0026] The beneficial effects of this invention are as follows: This invention uses the logging device itself to detect the well environment, and uses a traction cable to pull the logging device and transmit data, facilitating the device's entry into the well for detection. When a collapse occurs in the well, making it impossible to pull the logging device out using the traction cable, a rotary drive mechanism drives the conical drill bit to rotate, drilling through the collapsed soil. This achieves reverse drilling, i.e., drilling from bottom to top, causing the soil to fall downwards. A downward shoveling mechanism continues to shovel the soil downwards, and a climbing mechanism drives the logging device to climb within the well, allowing the entire device to move upwards and be successfully removed from the well. This avoids the problem of the logging device being damaged or unable to be retrieved due to a collapse. Attached Figure Description

Detailed Implementation

[0041] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0042] Example

[0043] Referring to Figures 1-11, this embodiment provides a logging device with a stuck-in-well release mechanism, comprising:

[0044] Logging device body 1;

[0045] Traction cable 7, which is connected to the logging device body 1;

[0046] A conical drill bit 2 is located at the top of the logging device body 1 and is rotatably connected to the logging device body 1. The outer contour dimension of the conical drill bit 2 is larger than the outer contour dimension of the logging device body 1.

[0047] A rotary drive mechanism 3 is installed on the top of the logging device body 1 and located below the conical drill bit 2. The rotary drive mechanism 3 is connected to the conical drill bit 2 and is used to drive the conical drill bit 2 to rotate.

[0048] A downward shoveling mechanism is located below the conical drill bit 2 and connected to the logging device body 1. The downward shoveling mechanism can retract and extend. The outer contour dimension of the downward shoveling mechanism after retraction is less than or equal to the outer contour dimension of the conical drill bit 2.

[0049] A climbing mechanism is located below the downward shoveling mechanism and connected to the logging device body 1. The climbing mechanism is used to drive the logging device body 1 to climb in the well.

[0050] This embodiment improves the external structure of the existing logging device by adding a conical drill bit 2, a rotary drive mechanism 3, a downward shoveling mechanism, and a climbing mechanism. The internal structure of the existing logging device, including the structural parts used for well exploration, is not improved and existing technologies can be directly adopted, effectively reducing the improvement cost.

[0051] In this embodiment, the logging device body 1 is used to detect the environment inside the well. The logging device body 1 is pulled along by the traction cable 7 to transmit data, facilitating its entry into the well for detection. If a collapse occurs inside the well, preventing the logging device body 1 from being pulled out via the traction cable 7, the rotary drive mechanism 3 drives the conical drill bit 2 to rotate, drilling away the collapsed soil. This achieves reverse drilling, i.e., drilling from bottom to top, causing the soil to fall downwards. A downward shoveling mechanism further shovels the soil downwards, and a climbing mechanism drives the logging device body 1 to climb within the well, allowing it to move upwards and be successfully removed from the well. This avoids damage to the logging device body 1 or the inability to retrieve it due to a collapse.

[0052] In this embodiment, the conical drill bit 2 is located at the top of the logging device body 1, and the outer contour dimension of the conical drill bit 2 is larger than the outer contour dimension of the logging device body 1. Therefore, when a collapse occurs, the collapsed soil falls on the conical drill bit 2, effectively protecting the logging device body 1.

[0053] In this preferred embodiment, when a collapse occurs, the downward shoveling mechanism retracts, bringing it below the conical drill bit 2. The outer contour of the retracted downward shoveling mechanism is less than or equal to the outer contour of the conical drill bit 2. This allows the conical drill bit 2 to rotate, causing the soil to fall downwards. The downward shoveling mechanism then continues to shovel the soil downwards, ensuring that the soil is effectively and smoothly transported downwards and quickly clearing the collapsed soil above.

[0054] In a further preferred embodiment, the well logging device's in-well unsticking device further includes a spiral conveying mechanism 6 located below the conical drill bit 2 and above the climbing mechanism. The spiral conveying mechanism 6 includes a spiral conveying sleeve 61 and a first rotary drive assembly 60. The spiral conveying sleeve 61 is fitted over the body 1 of the well logging device and is rotatable relative to the body 1. The first rotary drive assembly 60 is mounted on the body 1 of the well logging device and connected to the spiral conveying sleeve 61. The rotation direction of the spiral conveying sleeve 61 is opposite to the rotation direction of the conical drill bit 2. The conveying direction of the spiral conveying sleeve 61 is from top to bottom.

[0055] As the collapsed soil falls downwards via the conical drill bit 2 and the downward shoveling mechanism, the first rotary drive assembly 60 further drives the spiral conveyor sleeve 61 to rotate, and the spiral conveyor sleeve 61 continues to transport the soil downwards under the action of the spiral conveyor sleeve 61, ensuring that the soil is effectively and quickly transported downwards, so as to quickly remove the collapsed soil above.

[0056] In this embodiment, the rotation direction of the spiral conveyor sleeve 61 is opposite to that of the conical drill bit 2, thereby offsetting the rotational torque on the logging device body 1, so that the logging device body 1 will not rotate on its own, ensuring the effective and stable operation of the whole.

[0057] In this embodiment, the first rotary drive assembly 60 can be an existing hub motor (see Figures 1 and 2); alternatively, it can also employ an existing motor + gear structure. Specifically, the first rotary drive assembly 60 includes a motor mounted on the logging device body 1, a gear mounted on the motor output shaft, and an external gear ring mounted on the spiral conveying sleeve 61. The gear meshes with the external gear. When the motor starts, it drives the gear to rotate, which in turn drives the external gear ring to rotate, which in turn drives the spiral conveying sleeve 61 to rotate. Other existing drive structures can also be used.

[0058] In a further preferred embodiment, the conical drill bit 2 has a hollow structure with both ends open. A support column 12 and a conical support head 11 are sequentially connected to the middle of the top of the logging device body 1, and the conical drill bit 2 is fitted onto the conical support head 11. The conical support head 11 effectively supports the conical drill bit 2, ensuring its structural strength. The design of the support column 12 provides installation space for the rotary drive mechanism 3 and retracts it below the conical drill bit 2, effectively protecting the rotary drive mechanism 3. The support column 12 and the conical support head 11 form an umbrella-shaped structure.

[0059] In this preferred embodiment, the rotary drive mechanism 3 includes a rotary drive motor 30, a drive gear 31, and an internal gear ring 32. The large end of the tapered drill bit 2 is provided with the internal gear ring 32. The rotary drive motor 30 is mounted on the logging device body 1, and the drive gear 31 is mounted on the output shaft of the rotary drive motor 30. The drive gear 31 meshes with the internal gear ring 32. The rotary drive motor 30 drives the drive gear 31 to rotate, which in turn drives the internal gear ring 32 to rotate, thereby causing the tapered drill bit 2 to rotate on the tapered support head 11. The rotary drive motor 30 is mounted on the logging device body 1 via a support 33.

[0060] In a further preferred embodiment, the downward shoveling mechanism includes a downward shoveling body 4, and the number of downward shoveling bodies 4 is at least three. Multiple downward shoveling bodies 4 are evenly distributed along the outer circumference of the logging device body 1. Referring to Figure 1, the number of downward shoveling bodies 4 is three, but this is not limited and depends on the actual situation.

[0061] For each of the downward shovel bodies 4: the downward shovel body 4 includes a first retraction and expansion assembly 40, a shovel plate 43, a translation seat 42, a linear motion drive assembly 46, and a first support seat 41. The inner side of the first support seat 41 is connected to the logging device body 1 through the first retraction and expansion assembly 40. The translation seat 42 is movably mounted on the first support seat 41. The first support seat 41 is connected to the translation seat 42 through the linear motion drive assembly 46. The linear motion drive assembly 46 drives the translation seat 42 relative to the [unclear text - possibly a component or component]... The first support base 41 moves up and down. There are multiple shovel plates 43 arranged horizontally and vertically on the outer surface of the translation base 42. The shovel plates 43 are rotatably connected to the translation base 42. When the translation base 42 moves upward relative to the first support base 41, the shovel plates 43 close relative to the translation base 42. When the translation base 42 moves downward relative to the first support base 41, the shovel plates 43 open relative to the translation base 42. The opening angle of the shovel plates 43 relative to the translation base 42 is 15°-90°.

[0062] The first retraction and expansion assembly 40 drives the first support base 41 to retract and expand relative to the logging device body 1, thereby realizing the retraction and expansion of the downward shoveling body 4 and thus the retraction and expansion of the downward shoveling mechanism. The degree of retraction and expansion of the first support base 41 relative to the logging device body 1 is adjusted according to the collapse situation and the downward shoveling situation. When a landslide occurs, the conical drill bit 2 rotates, and the downward shoveling mechanism shovels soil downwards. Specifically, the first retractable and expandable assembly 40 retracts the downward shoveling body 4 below the conical drill bit 2. The linear motion drive assembly 46 drives the translation seat 42 to reciprocate up and down relative to the first support seat 41. When the translation seat 42 moves upwards relative to the first support seat 41, the shovel plate 43 closes relative to the translation seat 42, making the shovel plate 43 fit against the outer side of the translation seat 42. When the translation seat 42 moves downwards relative to the first support seat 41, the shovel plate 43 opens relative to the translation seat 42, that is, when the shovel plate 43 moves downwards, it shovels soil downwards. In this way, when the multiple shovel plates 43 on the translation seat 42 reciprocate up and down, the shovel plates 43 continuously shovel the soil downwards, ensuring that the soil falls effectively and quickly downwards. The design of multiple downward shovel bodies 4 further improves the rate at which the landslide soil falls rapidly.

[0063] In this embodiment, the angle at which the shovel plate 43 opens relative to the translation seat 42 is preferably 30°-60°. The specific angle depends on the actual situation and is not limited thereto.

[0064] In this embodiment, the translation seat 42 can be a single unit; or it can be composed of multiple plates, with the plates arranged side by side at equal intervals on the outer surface of the first support seat 41, as shown in Figures 1 and 3-6. The number of plates is three, and the specific number of plates depends on the actual situation.

[0065] In a further preferred embodiment, the first retractable / expandable assembly 40 includes a support arm 401, a connecting rod 402, and a first eccentric motor 403. The support arm 401 has a strip-shaped window 4010, and one end of the connecting rod 402 has a first oblong hole 4020, with the connecting rod 402 located within the strip-shaped window 4010. One end of the support arm 401 is rotatably connected to the logging device body 1, forming a first hinge point. The other end of the support arm 401 is rotatably connected to the first support base 41, forming a second hinge point. One end of the connecting rod 402 is rotatably connected to the logging device body 1, forming a third hinge point, and the other end of the connecting rod 402 is rotatably connected to the first support base 41, forming a fourth hinge point. The first hinge point, the second hinge point, the third hinge point, and the fourth hinge point form a parallelogram linkage mechanism. The first eccentric motor 403 is mounted on the support arm 401, and the first eccentric shaft 4030 of the first eccentric motor 403 is inserted into the first oblong hole 4020.

[0066] As shown in Figure 4, when the first retraction and unfolding assembly 40 is working, the first eccentric motor 403 starts, driving the first eccentric shaft 4030 to rotate. When the first eccentric shaft 4030 rotates, it moves within the first oblong hole 4020. When the first eccentric shaft 4030 rotates and drives the connecting rod 402 to move to the upper left, a parallelogram linkage mechanism is formed between the first hinge point, the second hinge point, the third hinge point, and the fourth hinge point, which drives the support arm 401 to rotate upward. As a result, the support arm 401 drives the first support seat 41 to retract. When the first eccentric shaft 4030 rotates and drives the connecting rod 402 to move to the lower right, the support arm 401 rotates downward. As a result, the support arm 401 drives the first support seat 41 to unfold. This achieves the retraction and unfolding of the downward shovel body 4.

[0067] In this embodiment, both ends of the support arm 401 are rotatably connected to the first support base 41 and the logging device body 1 respectively via the first rotating shaft 44. Both ends of the connecting rod 402 are rotatably connected to the first support base 41 and the logging device body 1 respectively via the second rotating shaft 45. In this embodiment, the logging device body 1 is provided with a first installation notch 101, and the number of first installation notches 101 is the same as the downward shovel body 4 and their positions are opposite. One end of the first retractable and expandable component 40 is located inside the first installation notch 101, improving the stability of the installation.

[0068] In a further preferred embodiment, the linear motion drive assembly 46 includes a second eccentric motor 460, a first slider 461, a second slider 463, and a transition gear 462. The second eccentric motor 460 is mounted on the support arm 401, and the first slider 461 is movably mounted on the support arm 401. One end of the first slider 461 is provided with a second oblong hole 4611, and the other end is provided with a first rack 4610. The second eccentric shaft 4601 of the second eccentric motor 460 is inserted into the second oblong hole 4611. The transition gear 462 rotates... The first rack 4610 is movably mounted on the support arm 401 and meshes with the transition gear 462. The translation seat 42 is movably mounted on the first support seat 41 via the second slider 463, which is provided with a second rack 4630. When the first retraction and expansion assembly 40 drives the first support seat 41 to retract, the transition gear 462 meshes with the second rack 4630. When the first retraction and expansion assembly 40 drives the first support seat 41 to expand, the transition gear 462 disengages from the second rack 4630.

[0069] As shown in Figure 4, when the linear motion drive assembly 46 is working, the second eccentric motor 460 starts, driving the second eccentric shaft 4601 to rotate. When the second eccentric shaft 4601 rotates, it moves within the second oblong hole 4611, thereby driving the first slider 461 to reciprocate on the support arm 401. When the downward shovel body 4 retracts relative to the logging device body 1, the transition gear 462 meshes with the second rack 4630. Therefore, when the first slider 461 reciprocates on the support arm 401, the first rack 4610 drives the transition gear 462 to reciprocate. Under the action of the second rack 4630, the transition gear 462 reciprocates, thereby driving the second slider 463 to reciprocate up and down on the first support seat 41. The second slider 463 is connected to the translation seat 42, so the reciprocating up and down movement of the second slider 463 synchronously drives the translation seat 42 to reciprocate up and down on the first support seat 41. When the downward shovel body 4 unfolds relative to the logging device body 1, the transition gear 462 and the second rack 4630 do not mesh.

[0070] In this embodiment, the shovel plate 43 is rotatably connected to the translation seat 42 via the third rotating shaft 430.

[0071] Referring to Figure 6, in this preferred embodiment, the end of the shovel plate 43 is provided with a limiting protrusion 431. When the shovel plate 43 opens relative to the translation seat 42 until the limiting protrusion 431 abuts against the translation seat 42, the shovel plate 43 stops rotating relative to the translation seat 42. The limiting protrusion 431 serves to limit the degree of opening of the shovel plate 43 relative to the translation seat 42.

[0072] Referring to Figure 10, in this embodiment, the support arm 401 is provided with an installation window 4011 for accommodating the first eccentric motor 403, the second eccentric motor 460 and the first slider 461. The support arm 401 is also provided with a notch 4012 for accommodating the transition gear 462.

[0073] In a further preferred embodiment, the climbing mechanism includes a climbing body 5, and the number of climbing bodies 5 is at least three. Multiple climbing bodies 5 are evenly distributed along the outer circumference of the logging device body 1. For each climbing body 5: the climbing body 5 includes a second retractable / deployable assembly 50, a second support base 51, a second rotary drive assembly 53, and tracks 52. The inner side of the second support base 51 is connected to the logging device body 1 via the second retractable / deployable assembly 50. Multiple tracks 52 are arranged side-by-side at equal intervals on the outer side of the second support base 51, and each track 52 is rotatable relative to the second support base 51. The number of second rotary drive assemblies 53 is the same as the number of tracks 52, and their positions are opposite. The second rotary drive assemblies 53 are mounted on the second support base 51, and multiple second rotary drive assemblies 53 are respectively connected to multiple tracks 52.

[0074] In this embodiment, the structure of the second retraction and deployment assembly 50 is the same as that of the first retraction and deployment assembly 40, namely, it includes a support arm 401, a first eccentric motor 403, and a connecting rod 402. The support arm 401 of the second retraction and deployment assembly 50 connects the second support base 51 and the logging device body 1. The retraction and deployment principle of the second retraction and deployment assembly 50 is detailed in the description of the first retraction and deployment assembly 40.

[0075] In this embodiment, the logging device body 1 is provided with a second installation notch 102, and the number of second installation notches 102 is the same as that of the climbing body 5 and their positions are opposite. One end of the second retractable and deployable component 50 is located inside the second installation notch 102, thereby improving the stability of the installation.

[0076] When the climbing mechanism is in operation, the climbing body 5 unfolds relative to the logging device body 1, and the tracks 52 are pressed tightly against the well wall. The second rotary drive assembly 53 is activated, driving the tracks 52 to move, causing the tracks 52 to climb upwards. Referring to Figure 1, there are three climbing bodies 5; the specific number is not limited and depends on the actual situation. The design of multiple climbing bodies 5 ensures the overall upward climbing capability.

[0077] In a preferred embodiment, the second rotary drive assembly 53 includes a drive motor 530, a worm gear 531, a worm wheel 532, and a drive gear 533. The conveying surface of the track 52 is provided with a plurality of toothed grooves 520 at equal intervals. The drive motor 530 is mounted on the second support base 51. The output shaft of the drive motor 530 is connected to the worm gear 531. The worm wheel 532 is connected to the drive gear 533 as a whole and is rotatably mounted on the second support base 51. The worm gear 531 meshes with the worm wheel 532, and the drive gear 533 meshes with the toothed grooves 520.

[0078] When the second rotary drive assembly 53 is working, the drive motor 530 starts, driving the worm 531 to rotate. The rotation of the worm 531 drives the worm wheel 532 to rotate, which in turn drives the drive gear 533 to rotate. The teeth on the drive gear 533 mesh with the tooth grooves 520 on the track 52, thus driving the track 52 to move. Because the worm 531 and worm wheel 532 have a reverse self-locking function, when the drive motor 530 stops moving, the second rotary drive assembly 53 will not rotate in the reverse direction, and the whole machine will not move downwards, ensuring that the climbing mechanism always climbs upwards.

[0079] In the above-mentioned second rotary drive assembly 53, one second rotary drive assembly 53 is configured for each track 52, and each second rotary drive assembly 53 includes a drive motor 530, a worm gear 531, a worm wheel 532 and a drive gear 533.

[0080] Referring to Figures 8 and 9, there are three tracks 52, and only two drive motors 530, three drive gears 533, two worms 531, and two worm wheels 532 are configured. The three drive gears 533 and two worm wheels 532 are rotatably mounted on the second support base 51 via a drive shaft 534. The three drive gears 533 mesh with the tooth grooves 520 of the three tracks 52 respectively. The output shafts of the two drive motors 530 are respectively connected to the two worms 531, and the two worms 531 mesh with the two worm wheels 532 respectively. Compared with the structure in which each track 52 is equipped with a separate second rotary drive assembly 53, this structure reduces the use of one drive motor 530, saving energy while ensuring the stability of power drive and transmission.
