Description

Technical Field

[0002] According to the requirements of the "Safety Specifications for Passenger Aerial Ropeways", the driving machine of the passenger aerial ropeway must be equipped with a main drive device and an emergency drive device. When the main drive device is working, the emergency drive device should be completely disengaged from the main drive device, and the two shall not interfere with each other. According to the requirements of the specifications, when the main drive device fails and cannot work normally, the emergency drive device should be quickly put into operation within the specified time. In the related technology, the emergency drive device is switched to a lifting type. An external thread is machined on the transmission shaft of the emergency drive device and a handwheel is provided. The handwheel is threadedly connected to the transmission shaft. By rotating the handwheel in different directions, the handwheel moves up and down along the axis of the transmission shaft, thereby driving the gear to disengage or engage with the open gear ring. Since the gear is driven to engage with the gear ring along the axis direction by rotating the handwheel, it is difficult to align the teeth, which is time-consuming and labor-intensive, and it is not easy for people to operate.

[0044] Driving body 200, gear 2001. DETAILED DESCRIPTION

[0045] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0046] like Figures 1 to 7 As shown, the cableway system according to the embodiment of the present invention includes a cableway body and an emergency driving device 1000 .

[0047] The cableway body comprises a frame and a gear ring arranged on the frame.

[0048] The emergency drive device 1000 includes a drive body 200 and a cableway emergency drive switching device 100. The drive body 200 has a gear 2001. The cableway emergency drive switching device 100 includes a mounting frame 2, a rotating bracket 1 and a crank connecting rod mechanism 3. The mounting frame 2 is arranged on a frame. The drive body 200 is mounted on the rotating bracket 1, that is, the drive body 200 can be mounted on the rotating bracket 1. The rotating bracket 1 is rotatably arranged on the mounting frame 2 between a disengagement position in which the gear 2001 can be disengaged from the gear ring and a working position in which the gear 2001 can be meshed with the gear ring. The rotation axis of the rotating bracket 1 is aligned with the vertical direction (e.g., Figure 1 The angle between the upper and lower directions (in the vertical direction) can be less than or equal to a preset value. The crank connecting rod mechanism 3 is connected to the rotating bracket 1 so as to drive the rotating bracket 1 to rotate between the working position and the disengaged position.

[0049] In other words, when the rotating bracket 1 is located at the disengaged position, the gear 2001 of the driving body 200 installed on the rotating bracket 1 is disengaged from the ring gear, and the emergency drive device 1000 is in a non-working state; when the crank-connecting rod mechanism 3 drives the rotating bracket 1 to rotate (rotate) from the disengaged position to the working position, the gear 2001 of the driving body 200 installed on the rotating bracket 1 is engaged with the ring gear, and the emergency drive device 1000 is in a working state.

[0050] When the cableway system of the embodiment of the present invention needs the emergency drive device 1000 to be put into operation to drive the ring gear to rotate, the crank-connecting rod mechanism 3 drives the rotating bracket 1 to rotate around the rotation axis so that the rotating bracket 1 rotates to the working position, so that the gear 2001 of the driving body 200 engages with the ring gear, and then the driving body 200 of the emergency drive device 1000 can be started to rotate the gear 2001, thereby driving the ring gear to rotate, thereby completing the driving of the ring gear by the emergency drive device 1000.

[0051] The angle between the rotation axis of the rotating bracket 1 of the cableway emergency drive switching device 100 of the embodiment of the present invention and the vertical direction can be less than or equal to a preset value, and the angle between the axis of the ring gear and the vertical direction can be less than or equal to a preset value, that is, the rotation of the rotating bracket 1 around the rotation axis is a rotation in the horizontal direction or a rotation close to the horizontal direction, and the gear 2001 of the driving body 200 installed on the rotating bracket 1 is a movement in the horizontal direction or a movement close to the horizontal direction, that is, the gear 2001 approaches the ring gear from the side of the ring gear and meshes with the ring gear.

[0052] In the related art, the gear of the emergency drive device is driven by the hand wheel to move axially, so that the gear meshes with the gear ring in the axial direction. However, during the meshing process of the gear with the gear ring in the axial direction, the gear and the gear ring need to be aligned and meshed in the axial direction, but the aligning of the gears in the axial direction is difficult. The cableway emergency drive switching device 100 of the embodiment of the present invention realizes the approach of the gear 2001 to the gear ring from the side of the gear ring (the side direction of the gear ring includes the radial direction of the gear ring) and meshing with the gear ring. The aligning and meshing process on the side of the gear ring is less difficult than the aligning and meshing process in the axial direction, and is easier to operate.

[0053] In addition, the cableway emergency drive switching device 100 of the embodiment of the present invention adopts a crank-connecting rod mechanism 3 to drive the rotating bracket 1 to rotate around the rotation axis. The crank-connecting rod mechanism 3 serves as a driving member for driving the rotating bracket 1 to rotate. Its structure is simple and lightweight, and it is easy to use. It overcomes the shortcomings of the related art that turning the hand wheel requires overcoming large thread friction resistance, is difficult to operate, is time-consuming and labor-intensive, and difficult to maintain.

[0054] The cableway emergency drive switching device 100, the emergency drive device 1000 and the cableway system of the embodiment of the present invention drive the gear 2001 to move in the horizontal direction or nearly in the horizontal direction through the crank-connecting rod mechanism 3, so that the gear 2001 can be meshed with the gear ring from the side of the gear ring. Compared with the related art, the meshing process of the gear 2001 and the gear ring is simple and easy to operate, and the use of the crank-connecting rod mechanism 3 to drive the gear 2001 to move also overcomes the disadvantage of large thread friction resistance in the related art, and is easy to use.

[0055] In order to make the technical solution of the present application easier to understand, the following describes the technical solution of the present invention by taking the extension direction of the rotation axis of the rotating bracket 1 as an example, wherein the extension direction of the rotation axis of the rotating bracket 1 is consistent with the up-down direction. Figure 1 and Figure 4 shown.

[0056] See also Figures 1 to 7 The cableway system of the embodiment of the present invention includes a cableway body and an emergency driving device 1000 .

[0057] The cableway body has a frame, a gear ring, a driving wheel and a main driving part. The driving wheel is arranged on the frame, and the gear ring is arranged on the driving wheel. Under normal circumstances, the main driving part serves as a power source to provide operating power for the driving wheel. When the main driving part is in operation, the rotating bracket 1 is located in the disengaged position, and the gear 2001 of the emergency driving device 1000 is disengaged from the gear ring. At this time, the emergency driving device 1000 is in a non-working state. When the main driving part fails and cannot work normally, the rotating bracket 1 rotates to the working position, and the gear 2001 of the emergency driving device 1000 is meshed with the gear ring. At this time, the emergency driving device 1000 is in a working state, and the emergency driving device 1000 provides operating power for the cableway system.

[0058] The emergency driving device 1000 includes a driving body 200 and a cableway emergency driving switching device 100 .

[0059] The driving body 200 has a gear 2001 .

[0060] The cableway emergency drive switching device 100 includes a mounting frame 2 , a rotating bracket 1 , a crank connecting rod mechanism 3 , a fixing pin 4 , a spherical bearing 5 , an adjusting screw 6 , a first nut 81 , a second nut 82 , a first detection switch 71 and a second detection switch 72 .

[0061] The mounting frame 2 is arranged on the frame.

[0062] The driving body 200 is installed on the rotating bracket 1, and the rotating bracket 1 is rotatably provided on the mounting frame 2 between a disengagement position in which the gear 2001 can be disengaged from the gear ring and a working position in which the gear 2001 and the gear ring can be meshed. That is to say, the rotating bracket 1 can rotate relative to the frame, and the angle between the rotation axis of the rotating bracket 1 and the vertical direction is zero.

[0063] The crank-connecting rod mechanism 3 is connected to the rotating bracket 1 so as to drive the rotating bracket 1 to rotate between the working position and the disengaged position.

[0064] The crank-connecting rod mechanism 3 comprises a crank 31 , a connecting rod 32 , a limiting rod 33 and a rocker rod 34 .

[0065] The crank 31 is rotatably arranged on the mounting frame 2 between an initial position and a locking position, wherein when the crank 31 is in the initial position, the rotating bracket 1 is in the disengaged position, and when the crank 31 is in the locking position, the rotating bracket 1 is in the working position. The connecting rod 32 has a first end 321 and a second end 322, wherein the first end 321 is hinged to the crank 31, and the second end 322 is hinged to the rotating bracket 1.

[0066] The crank-connecting rod mechanism 3 is a driving member for driving the rotating bracket 1 to rotate. The cableway emergency drive switching device 100 rotates the crank 31 to make the crank 31 rotate around the mounting frame 2, thereby driving the connecting rod 32 to move, and further driving the rotating bracket 1 to rotate. Figure 1 , Figure 4 , Figure 6 and Figure 7 As shown, the rotating bracket 1 rotates around the rotating axis, and the extending direction of the rotating axis is the up and down direction, that is, the movement of the rotating bracket 1 is the movement in the horizontal direction. Therefore, the crank 31, the connecting rod 32 and the rotating bracket 1 can be analogous to a crank-connecting rod slider mechanism, and the rotating bracket 1 can be analogous to the slider in the crank-connecting rod slider mechanism.

[0067] When the extension direction of the crank of the crank-connecting rod slider mechanism coincides with (is the same as) the extension direction of the connecting rod, that is, the angle between the crank and the connecting rod is 0° (the crank and the connecting rod coincide) or the angle between the crank and the connecting rod is 180°, if an external force is applied to the slider side to make the slider act as an active member, the crank-connecting rod slider mechanism cannot be driven to move. The angle between the crank and the connecting rod of the crank-connecting rod slider mechanism is 0°, which is the first dead point position, and the angle between the crank and the connecting rod is 180°, which is the second dead point position. If an external force is applied from the crank side to make the crank act as an active member, the crank-connecting rod slider mechanism does not have a dead point position.

[0068] That is to say, when the crank-connecting rod mechanism 3 of the cableway emergency drive switching device 100 of the embodiment of the present invention drives the rotating bracket 1 to move, when the extension direction of the crank 31 and the extension direction of the connecting rod 32 coincide (are the same), that is, the extension direction of the line between the rotation point between the crank 31 and the mounting frame 2 and the hinge point between the crank 31 and the first end 321 (for the convenience of the following description, this line is called the crank line) coincides with the extension direction of the line between the first end 321 and the second end 322 (this line is called the connecting rod line). If the angle between the crank line and the connecting rod line is 180° (the second dead point position), the rotating bracket 1 is located at the position where the gear 2001 is farthest from the ring gear. If the angle between the crank line and the connecting rod line is 0° (the first dead point position), the rotating bracket 1 is located at the position where the gear 2001 is most closely meshed with the ring gear (the closest distance). At this time, if the crank 31 is rotated, the rotating bracket 1 can be driven to rotate through the connecting rod 32, but if an external force is applied from the rotating bracket 1 side, the crank-connecting rod mechanism 3 cannot be driven to rotate. In other words, when the crank-connecting rod mechanism 3 is at the dead point position (the first dead point position or the second dead point position), the reaction force of the meshing of the gear 2001 and the ring gear will not change the position of the rotating bracket 1.

[0069] exist Figures 1 to 7 In the embodiment shown, the initial position of the crank 31 is located between the first dead point position and the second dead point position of the crank-connecting rod mechanism 3, that is, Figures 1 to 7 In the illustrated embodiment, the crank-connecting rod mechanism 3 has only one dead point position, namely the first dead point position. At this dead point position of the crank-connecting rod mechanism 3, the angle between the crank line and the connecting rod line is 0° (ie, the crank 31 and the connecting rod 32 coincide with each other).

[0070] The connecting rod 32 is provided with a limiting groove 323, which is located between the first end 321 and the second end 322. The limiting rod 33 is provided on the crank 31, and the rotation axis of the crank 31 passes through the limiting rod 33, that is, the rotation axis of the crank 31 relative to the mounting frame 2 passes through the limiting rod 33.

[0071] When the crank 31 is located at the initial position, the first end 321 and the second end 322 are located between at least a portion of the limiting groove 323 and the limiting rod 33 in the rotation direction of the crank 31, and at least a portion of the bottom wall surface of the limiting groove 323 is adjacent to the first end 321 and the second end 322 in the rotation direction of the crank 31, so that the limiting groove 323 is adjacent to the dead point position of the crank-connecting rod mechanism 3. When the crank 31 is located at the locking position, the limiting rod 33 is fitted in the limiting groove 323, and the limiting rod 33 abuts against or is adjacent to the bottom wall surface of the limiting groove 323 in the rotation direction of the crank 31.

[0072] In order to make the technical solution of the present application easier to understand, the technical solution of the present application is further described below by taking the crank 31 rotating clockwise from the initial position to the locking position and the crank 31 rotating counterclockwise from the locking position to the initial position as an example. When the crank 31 is at the initial position, the first end 321 and the second end 322 are located downstream of the limiting rod 33 in the clockwise direction, and the at least a portion of the limiting groove 323 is located downstream of the first end 321 and the second end 322 in the clockwise direction.

[0073] That is to say, when the crank 31 rotates from the initial position toward the locking position in the clockwise direction, after the crank 31 rotates a certain angle, the limit rod 33 and the first end 321 and the second end 322 are opposite to each other in the radial direction of the rotation circle of the crank 31. After the crank 31 continues to rotate a certain angle, the limit rod 33 and at least a part of the limit groove 323 are opposite to each other in the radial direction of the rotation circle of the crank 31.

[0074] Since the rotation axis of the crank 31 passes through the limiting rod 33, when the limiting rod 33 is opposite to the first end 321 and the second end 322 in the radial direction of the circumference of the crank 31, the crank line and the connecting rod line coincide (the angle between the crank line and the connecting rod line is 0°), forming a dead point (i.e., the first dead point position). Then the crank 31 is continuously rotated to make the crank 31 pass the dead point position. After the crank 31 continues to rotate by a certain angle, at least a portion of the limiting groove 323 located downstream of the first end 321 and the second end 322 in the clockwise direction is opposite to the limiting rod 33 in the radial direction of the circumference of the crank 311, that is, the limiting rod 33 abuts against or is adjacent to the bottom wall of the limiting groove 323 in the rotation direction of the crank 31.

[0075] Thus, at least a portion of the bottom wall surface of the limit groove 323 is adjacent to the first end 321 and the second end 322 in the rotation direction of the crank 31, so that when the crank 31 rotates from the initial position to the locking position, the crank 31 passes through the position where the crank 31 and the connecting rod 32 overlap, that is, the dead point position of the crank-connecting rod mechanism 3, and when the crank 31 is in the locking position, that is, when the limit rod 33 abuts against or is adjacent to the bottom wall surface of the limit groove 323 in the rotation direction of the crank 31, the crank 31 is adjacent to the dead point position of the crank-connecting rod mechanism 3.

[0076] See also Figure 7As shown, when the crank 31 is in the locked position, the crank 31 is blocked by the connecting rod 32 in the clockwise rotation direction, and the crank 31 has the dead point position in the counterclockwise rotation direction. That is to say, when the crank 31 is in the locked position, if the resistance of the meshing of the gear 2001 and the gear ring drives the rotating bracket 1 to swing, and if the swing drives the crank 31 to rotate clockwise, the clockwise rotation of the crank 31 is blocked by the connecting rod 32 (the bottom wall surface of the limiting groove 323), and if the swing drives the crank 31 to rotate counterclockwise, the crank connecting rod mechanism 3 will return to the dead point position, and at the dead point position, the crank connecting rod mechanism 3 is the most stable, and the meshing of the gear 2001 and the gear ring is tighter than when the crank 31 is in the locked position.

[0077] Therefore, the cableway emergency drive switching device 100 of the embodiment of the present invention has a self-locking property when the crank 3 of the crank-connecting rod mechanism 3 is located in the locked position through the setting of the limit groove 323 and the limit rod 33, which not only simplifies the mechanical structure but also improves the stability and reliability of the emergency drive device 1000 during operation.

[0078] Furthermore, the limiting rod 33 includes a first hinge shaft 331 and a limiting cylinder 332. The crank 31 is hinged to the mounting frame 2 through the first hinge shaft 331, and the limiting cylinder 332 is sleeved on the first hinge shaft 331. In other words, the rotation axis of the crank 31 is the axis of the first hinge shaft 331 of the limiting rod 33. The crank-connecting rod mechanism 3 not only has a self-locking characteristic through the limiting rod 33, but is also rotationally connected to the mounting frame 2 through the limiting rod 33, further simplifying the structure of the crank-connecting rod mechanism 3.

[0079] Specifically, see Figure 1 , Figure 2 and Figure 6 , Figure 7 As shown, the first hinge shaft 331 is arranged on the mounting frame 2 , the limiting cylinder 332 is arranged on the crank 31 , and the limiting cylinder 332 is sleeved on the first hinge shaft 331 and is rotatably connected to the first hinge shaft 331 .

[0080] Further, the limiting groove 323 includes a connected arc section 3231 and a transition section 3232, and the transition section 3232 is adjacent to the first end 321 relative to the arc section 3231. Specifically, the opening of the limiting groove 323 faces the limiting rod 33, and the transition section 3232 is adjacent to the first end 321 relative to the arc section 3231 in the length direction of the connecting rod 32. The depth of the transition section 3232 gradually increases in the direction toward the arc section 3231. The provision of the transition section 3232 allows the connecting rod 32 to avoid the relative movement path between the connecting rod 32 and the limiting rod 33 when the crank 31 rotates between the initial position and the locking position, so that the movement of the crank-connecting rod mechanism 3 is smoother and safer, and the safety of the cableway emergency drive switching device 100 when in use is further improved.

[0081] Furthermore, the crank 31 is provided with a first fixing hole 313, and the mounting frame 2 is provided with a second fixing hole 21. The fixing pin 4 can pass through the second fixing hole 21 and the first fixing hole 313 of the crank 31 located at the initial position to make the crank 31 stay at the initial position and the rotating bracket 1 stay at the disengaged position. The provision of the fixing pin 4 can fix the crank 31 located at the initial position, ensure the stability of the crank 31 when it is located at the initial position, and also ensure the stability of the rotating bracket 1 located at the disengaged position, thereby further improving the stability of the cableway emergency drive switching device 100 when it is in a non-working state.

[0082] The swing rod 34 is arranged on the crank 31. The arrangement of the swing rod 34 facilitates the operator to rotate the crank 31, thereby improving the convenience of using the crank-connecting rod mechanism 3.

[0083] Specifically, see Figure 6 and Figure 7 As shown, the rocker rod 34 is disposed at the end of the crank 31 adjacent to the limiting rod 33 .

[0084] One end of the joint bearing 5 is connected to the rotating bracket 1 , and the other end of the joint bearing 5 is connected to the second end portion 322 .

[0085] Optionally, the spherical bearing 5 includes an inner ring, an outer ring 51 and a rod 52, the inner ring has an outer spherical surface, the inner ring is rotatably connected to the rotating bracket 1, the outer ring 51 has an inner spherical surface that slides with the outer spherical surface of the inner ring, the outer ring 51 is sleeved on the inner ring, one end of the rod 52 is connected to the outer ring 51, and the other end of the rod 52 is connected to the second end 322.

[0086] It should be noted that the line between the first end 321 and the second end 322 of the axial connecting rod 32 of the spherical bearing 5 (i.e. the connecting rod line) is located on the same straight line. In other words, the connecting rod 32 and the spherical bearing 5 can be regarded as a connecting rod in the crank-connecting rod slider mechanism as a whole.

[0087] The end of the joint bearing 5 forms a ball joint with the rotating bracket 1. When the crank 1 moves between the initial position and the locking position to drive the connecting rod 32 to move, the first end 321 of the connecting rod 32 is displaced in the up-down direction. The joint bearing 5 is provided to provide a kinematic pair for the rotation of the connecting rod 32 in the up-down direction. When the crank-connecting rod mechanism 3 drives the rotating bracket 1 to rotate, the height position of the center of the end of the joint bearing 5 that is rotatably connected to the rotating bracket 1 will not change.

[0088] One of the second end 312 and the first end 321 is provided with a connecting hole 3211, and the other of the second end 312 and the first end 321 is provided with a second hinge shaft 3121, the first part of the second hinge shaft 3121 is fitted in the connecting hole 3211, and the first part of the second hinge shaft 3121 is separated from the wall of the connecting hole 3211.

[0089] When the crank 1 moves between the initial position and the locked position and drives the rotating bracket 1 to rotate through the connecting rod 32, the rotating bracket 1 is displaced in the front-back direction and the left-right direction, that is, the connecting rod 32 performs a deflection movement. The first part of the second hinge shaft 3121 is spaced apart from the wall surface of the connecting hole 3211 to provide space for the deflection movement of the connecting rod 32, and the joint bearing 5 provides a kinematic pair for the deflection movement of the connecting rod 32.

[0090] Specifically, Figure 6 and Figure 7 As shown, a connecting hole 3211 is provided on the second end portion 312 , and a second hinge shaft 3121 is provided on the first end portion 321 .

[0091] The adjusting screw 6 has a first thread segment and a second thread segment with opposite rotation directions, the first thread segment is threadedly connected to the second end portion 322, and the second thread segment is threadedly connected to the rod portion 52 of the spherical bearing 5. The cableway emergency drive switching device 100 shortens or lengthens the distance between the spherical bearing 5 and the connecting rod 32 by rotating the adjusting screw 6, that is, the distance between the spherical bearing 5 and the connecting rod 32 can be adjusted by adjusting the screw 6, that is, the distance between the driving body 200 on the rotating bracket 1 and the gear ring is adjusted, and then the distance between the gear 2001 of the driving body 200 and the gear ring is adjusted.

[0092] The cableway emergency drive switching device 100 can fine-tune the distance between the gear 2001 and the gear ring by rotating the adjusting screw 6, thereby improving the flexibility of the cableway system in adjusting the meshing degree between the gear 2001 and the gear ring.

[0093] It should be noted that the axis of the adjusting screw 6 coincides with the axis of the spherical bearing 5, and the connecting line between the first end 321 and the second end 322 of the connecting rod 32 (i.e., the connecting rod connecting line) is located on the same straight line. In other words, the connecting rod 32, the adjusting screw 6 and the spherical bearing 5 can be regarded as a connecting rod in the crank-connecting rod slider mechanism as a whole.

[0094] The first nut 81 is disposed on the first threaded section and abuts against the second end portion 322. The second nut 82 is disposed on the second threaded section and abuts against the spherical bearing 5.

[0095] Before rotating the adjusting screw 6 to shorten the distance between the spherical bearing 5 and the connecting rod 32 , it is necessary to first rotate the first nut 81 to disengage it from the second end 322 , and / or rotate the second nut 82 to disengage it from the spherical bearing 5 .

[0096] The provision of the first nut 81 and the second nut 82 increases the safety of shortening the distance between the spherical plain bearing 5 and the connecting rod 32 .

[0097] The first detection switch 71 is opposite to the rotating bracket 1 at the working position, and is used to detect whether the rotating bracket 1 is at the working position. When the first detection switch 71 detects the rotating bracket 1, the driving body 200 can be turned on to perform the driving operation.

[0098] The second detection switch 72 is opposite to the rotating bracket 1 at the disengaged position, and is used to detect whether the rotating bracket 1 is at the disengaged position. When the rotating bracket 1 of the emergency driving device 1000 is switched to the disengaged position, the active driving part can only be allowed to perform the driving operation after the second detection switch 72 detects a signal.

[0099] The provision of the first detection switch 71 and the second detection switch 72 improves the safety of the cableway emergency drive switching device 100, the emergency drive device 1000 and the cableway system, and ensures that the main drive part and the drive body 200 can work independently, and the drive body 200 and the main drive part do not interfere with each other.

[0100] Specifically, each of the first detection switch 71 and the second detection switch 72 is a travel switch.

[0101] Compared with the related art, the cableway emergency drive switching device 100 according to the embodiment of the present invention has the following advantages:

[0102] a. The gear 2001 of the driving body 200 installed on the rotating bracket 1 moves in the horizontal direction or nearly in the horizontal direction, so that the gear 2001 can be connected to the driving body 200 in a traditional shaft-spline manner, and the connection is firm and the position is fixed, avoiding the failure and maintenance that may be caused by the up and down movement of the transmission shaft and the gear in the related art. In addition, the gear 2001 approaches the gear ring from the side of the gear ring and meshes with the gear ring, which is easier than aligning the teeth along the axial direction.

[0103] b. The cableway emergency drive switching device 100 of the embodiment of the present invention adopts a design in which the crank connecting rod mechanism 3 drives the rotating bracket 1 and the driving body 200 to rotate around the rotation axis. The structure is simple and light, easy to use, time-saving and labor-saving, and easy to maintain.

[0104] c. The crank-connecting rod mechanism 3 has a self-locking property when the crank is in the locked position, thereby improving the safety and reliability of the cableway emergency drive switching device 100 .
