Description

Technical Field

[0001] The present invention relates to the technical field of cableway transportation equipment, and particularly to a cableway transportation shuttle. Background Art

[0002] At present, with the rapid development of the logistics industry, the transportation and logistics method of low-altitude erected tracks or cableways is more time-saving and labor-saving compared to traditional logistics; the shuttle is the main carrier of track-type or cableway-type logistics. Since the shuttle runs fixed on the cableway, and the cableway is generally set at a relatively high position and cannot be touched by ordinary people, the hanging box can only be loaded and unloaded at a professional logistics base, and cannot meet the application scenario of loading and unloading goods at any stop. Therefore, providing a new type of shuttle that can facilitate loading and unloading has become an urgent problem to be solved. Summary of the Invention

Detailed implementation manners

[0028] The following will further describe in detail the specific implementation manners of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0029] It should be understood that in the present invention, terms such as "first" and "second" are used to describe various information, but these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, "first" information can also be called "second" information, and similarly, "second" information can also be called "first" information.

[0030] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0031] As Figures 1 to 8 shown, a cableway transportation shuttle of a preferred embodiment of the present invention includes a traveling drive mechanism 1, a connecting frame 2, and a hanging box 4. The traveling drive mechanism 1 is connected to the connecting frame 2. A towing rope 8 and a winding and unwinding assembly capable of winding or unwinding the towing rope 8 are provided on the connecting frame 2. The top end of the towing rope 8 is connected to the winding and unwinding assembly, and the lower end of the towing rope 8 is detachably connected to the hanging box 4.

[0032] Based on the above technical solution, the hanging box 4 is connected to the connecting frame 2 through the towing rope 8. A winding and unwinding assembly capable of winding or unwinding the towing rope 8 is provided on the connecting frame 2. Thus, the length of the towing rope 8 can be adjusted through the winding and unwinding assembly, and then the relative position between the hanging box 4 and the connecting frame 2 can be adjusted, enabling the height of the hanging box 4 of the shuttle to be adjusted quickly and conveniently, allowing the operator to touch the hanging box 4, facilitating the installation and disassembly of the hanging box 4, and enabling the goods to be loaded and unloaded at any time when stopped. This avoids the problem in the prior art that the shuttle must load and unload goods at a professional logistics base and cannot meet the application scenario of loading and unloading goods at any stop.

[0033] Further, the winding and unwinding assembly includes a winding and unwinding drive device 7 and a rotating shaft 76 provided on the connecting frame 2. The towing rope 8 is wound around the rotating shaft 76. The winding and unwinding drive device 7 is connected to the rotating shaft 76, and the winding and unwinding drive device 7 can drive the rotating shaft 76 to rotate, so that the towing rope 8 is wound on the side wall of the rotating shaft 76 or the towing rope 8 is released from the side wall of the rotating shaft 76. By providing the winding and unwinding drive device 7, the towing rope 8 can be quickly wound or unwound, facilitating the adjustment of the position of the hanging box 4. In addition, by providing the rotating shaft 76, it is convenient to wind the towing rope 8, avoiding the towing rope 8 being damaged due to entanglement, and facilitating the quick reset of the towing rope 8.

[0034] Specifically, the winding and unwinding drive device 7 includes a lifting drive motor 71, a worm 72, and a worm gear 79. The worm 72 is connected to the power output end of the lifting drive motor 71. The worm gear 79 is located below the worm 72 and meshes with the worm 72. The output end of the worm gear 79 is connected to the rotating shaft 76. In an embodiment of the present application, the worm gear 79 is sleeved in the middle of the rotating shaft 76. Grooves (not shown in the figure) are provided on both the inner side of the worm gear 79 and the middle position of the rotating shaft 76. The two ends of a flat key (not shown in the figure) are respectively arranged in the groove on the inner side of the worm gear 79 and the groove in the middle position of the rotating shaft 76. When the lifting drive motor 71 rotates to drive the worm 72 to rotate, the worm 72 rotates and drives the worm gear 79 to rotate. The rotating worm gear 79 drives the rotating shaft 76 to rotate through a flat key (not shown in the figure). In another embodiment of the present application, the worm gear 79 is welded to the middle of the rotating shaft 76. When the lifting drive motor 71 rotates to drive the worm 72 to rotate, the worm 72 rotates and drives the worm gear 79 to rotate. The rotating worm gear 79 drives the rotating shaft 76 to rotate.

[0035] Further, the connecting frame 2 is provided with a clamping groove 22b, and the top of the hanging box 4 is provided with a positioning structure 41 adapted to the clamping groove 22b. In this embodiment, the cross-sectional dimension of the positioning structure 41 is smaller than that of the clamping groove 22b, so that the positioning structure 41 can smoothly extend into the clamping groove 22b without obstruction. The positioning structure 41 is provided with a clamping portion, and the clamping groove 22b is provided with a limiting member capable of cooperating with the clamping portion for positioning, so that the hanging box 4 can be limited by the limiting member and the clamping portion. In this embodiment, the positioning structure 41 is provided with a clamping groove 41b, and the lower end of the traction rope 8 is provided with a buckle 81 adapted to the clamping groove 41b. By providing the cooperation of the clamping groove 41b and the buckle 81, it is convenient to connect the connecting frame 2 and the hanging box 4, reduce the difficulty of installation and disassembly of the hanging box 4 and the connecting frame 2, so as to facilitate the installation and disassembly of the hanging box 4 and improve the efficiency of installing or disassembling the hanging box 4.

[0036] Further, the connecting frame 2 includes a main bracket 21 and a support frame 22. The main bracket 21 is arranged above the support frame 22, and the clamping groove 22b is arranged at the bottom of the main bracket 21. The support frame 22 includes a first support member and a second support member arranged oppositely. A clamping groove 22b is defined between the opposite ends of the first support member and the second support member. A winding and unwinding assembly is provided on the support frame 22, which is convenient for the installation of the winding and unwinding assembly. Among them, the rotating shaft 76 is arranged between the first support member and the second support member. The limiting member is a bolt 61 connected to the support frame 22. The bolt 61 can slide in the direction of the position where the clamping groove 22b is located. The first end of the bolt 61 can extend into or out of the clamping groove 22b. In some embodiments of the present application, the bolt 61 is connected to the first support member, and one end of the bolt 61 can extend into or out of the clamping groove 22b. The support frame 22 is provided with a driving device capable of driving the bolt 61 to reciprocate. In one embodiment of the present application, the clamping portion is a through hole or a groove on the positioning structure 41. Thus, the position of the hanging box 4 can be quickly positioned by the bolt 61 extending into the clamping groove 22b and engaging with the clamping portion of the positioning structure 41 at the top of the hanging box 4. If the clamping portion is a through hole, the second support member may also be provided with a receiving groove (not shown in the figure) for fixedly placing the first end of the bolt 61. The position of the hanging box 4 can be quickly positioned by extending the bolt 61 into the clamping groove 22b, engaging with the clamping portion of the positioning structure 41 at the top of the hanging box 4, and finally inserting it into the receiving groove. In another embodiment of the present application, the positioning structure 41 is any one of a T-shaped structure, an I-shaped structure, a 7-shaped structure or a Z-shaped structure. Correspondingly, the clamping portion is the horizontal portion above the T-shaped structure, I-shaped structure, 7-shaped structure or Z-shaped structure. After the bolt 61 extends into the clamping groove 22b, the bolt 61 is located below the clamping portion of the positioning structure 41 at the top of the hanging box 4, so as to engage with the clamping portion to quickly position the position of the hanging box 4.

[0037] Preferably, a driving device capable of driving the bolt 61 to reciprocate is provided on the support frame 22. Guide surfaces 22a are provided on both sides of the clamping groove 22b. The two guide surfaces 22a define the clamping groove 22b into an outward-expanded shape, increasing the port size of the clamping groove 22b and facilitating the accurate insertion of the positioning structure 41 into the clamping groove 22b. Thus, the position of the hanging box 4 is quickly positioned by extending the bolt 61 into the clamping groove 22b and clamping the clamping portion of the positioning structure 41 at the top of the hanging box 4.

[0038] In some embodiments of the present application, a bolt connection hole and an installation cavity through which the bolt 61 passes are provided on the support frame 22. The installation cavity is communicated with the clamping groove 22b. The bolt connection hole is in communication with the installation cavity and the cross-sectional dimension of the installation cavity is larger than that of the bolt connection hole. A limiting surface is formed at the junction of the installation cavity and the bolt connection hole. A limiting portion is provided at the first end of the bolt 61. A first return spring 77 is provided in the installation cavity. One end of the first return spring 77 abuts against the limiting surface on the side of the installation cavity close to the bolt connection hole, and the other end of the first return spring 77 abuts against the limiting portion, so that the first return spring 77 cannot pass through the bolt connection hole or the limiting portion and remains in the installation cavity. When the first return spring 77 is in a compressed state, in one embodiment of the present application, the first return spring 77 is located above or below the bolt 61. One end of the first return spring 77 abuts against and presses on the limiting surface and cannot pass through the bolt connection hole. The cross-sectional dimension of the other end of the first return spring 77 abutting against the limiting portion is smaller than that of the limiting portion and cannot pass through the limiting portion, so that the first return spring 77 cannot pass through the bolt connection hole or the limiting portion and remains in the installation cavity. In another embodiment of the present application, the first return spring 77 is sleeved on the bolt 61. The cross-sectional dimension of the end of the first return spring 77 abutting against the limiting surface is larger than that of the bolt connection hole and cannot pass through the bolt connection hole. The cross-sectional dimension of the other end of the first return spring 77 abutting against the limiting portion is smaller than that of the limiting portion and cannot pass through the limiting portion, so that the first return spring 77 cannot pass through the bolt connection hole or the limiting portion and remains in the installation cavity. Thus, the first return spring 77 ensures that the force direction of the bolt 61 is towards the direction of the clamping groove 22b, facilitating the quick restoration of movement when the lifting drive motor 71 rotates in reverse and facilitating automatic reset.

[0039] Preferably, a baffle 6 is provided on one side of the support frame 22. The second end of the bolt 61 is connected to the baffle 6. The baffle 6 is connected to the driving device. The driving device can drive the baffle 6 to reciprocate in the direction towards the position where the clamping groove 22b is located. Specifically, the second end of the bolt 61 is connected to the baffle 6. The first end of the bolt 61 can extend into the clamping groove 22b or be flush with the groove wall of the clamping groove 22b. Thus, the position of the bolt 61 is adjusted through the baffle 6, facilitating the connection between the bolt 61 and the driving device and facilitating the smooth movement of the bolt 61.

[0040] Preferably, the driving device is a worm 72. A screw rod portion is connected to the output end of the worm 72. A threaded hole adapted to the screw rod portion is provided on the baffle 6. The worm 72 is fixed to the threaded hole on the baffle 6 through the screw rod portion. When the lifting drive motor 71 rotates to drive the worm 72 to rotate, the worm 72 rotates and drives the baffle 6 to move.

[0041] Further, the driving device includes a connecting shaft 73 and a first gear 74 and a second gear 75 that mesh with each other. The output end of the worm 72 is connected to the first gear 74. One end of the connecting shaft 73 is connected to the support frame 22. A screw rod portion is provided at the second end of the connecting shaft 73. A threaded hole adapted to the screw rod portion is provided on the baffle 6. In an embodiment of the present application, the second gear 75 is sleeved on the connecting shaft 73 between the first end and the screw rod portion through a flat key, and the output end of the second gear 75 is connected to the connecting shaft 73. In an embodiment of the present application, the second gear 75 is welded between the first end and the screw rod portion of the connecting shaft 73, and the output end of the second gear 75 is connected to the connecting shaft 73. Thus, the driving device has a compact structure, which is convenient for improving the space utilization rate and facilitating the arrangement of each component.

[0042] Further, the support frame 22 is provided with a first connection hole, a second connection hole, and a third connection hole for installing the connection shaft 73 and connected in sequence from outside to inside. The cross-sectional dimensions of the first connection hole and the third connection hole are both larger than those of the second connection hole. A first limiting structure is provided between the first connection hole and the second connection hole, and a second limiting structure is provided between the third connection hole and the second connection hole. A second return spring 78 is provided in the third connection hole. A limiting device is provided at one end of the connection shaft 73 extending outside the third connection hole. One end of the second return spring 78 abuts against the second limiting structure. In this embodiment, both the first limiting structure and the second limiting structure are stepped surfaces. The other end of the second return spring 78 abuts against the limiting device, so that the second return spring 78 cannot pass through the second limiting structure or the limiting device and remains in the third connection hole. When the second return spring 78 is in a compressed state, in one embodiment of the present application, the second return spring 78 is located above or below the connection shaft 73. One end of the second return spring 78 abuts against and presses on the second limiting structure and cannot pass through the second connection hole. The cross-sectional dimension of the other end of the second return spring 78 abutting against the limiting device is smaller than the cross-sectional dimension of the limiting portion and cannot pass through the limiting device, so that the second return spring 78 cannot pass through the second connection hole or the limiting device and remains in the third connection hole. In another embodiment of the present application, the second return spring 78 is sleeved on the connection shaft 73. The cross-sectional dimension of the end of the second return spring 78 abutting against the second limiting structure is larger than the cross-sectional dimension of the second connection hole and cannot pass through the second connection hole. The cross-sectional dimension of the other end of the second return spring 78 abutting against the limiting device is smaller than the cross-sectional dimension of the limiting device and cannot pass through the limiting device, so that the second return spring 78 cannot pass through the second connection hole or the limiting device and remains in the third connection hole. Thus, when the lifting drive motor 71 rotates to drive the baffle 6 to move outwards, the second return spring 78 will ensure that the force direction of the connection shaft 73 is towards the direction of the clamping groove 22b, which is convenient for the lifting drive motor 71 to quickly resume movement when reversing and is convenient for automatic reset. A limiting step structure adapted to the first limiting structure is provided on the connection shaft 73, so as to limit the connection shaft 73 and prevent its movement range from being too large.

[0043] In addition, the cableway transportation shuttle further includes a locking detection device (not shown in the figure) that detects whether the latch pin 61 is stuck in the clamping portion of the positioning structure 41 and fixes the hanging box 4 to the connecting frame 2. The locking detection device is used to detect whether the clamping portion of the positioning structure 41 of the hanging box 4 is clamped in place by the latch pin 61. When the latch pin 61 clamps the clamping portion of the positioning structure 41, the hanging box 4 is fixed to the connecting frame 2. In this embodiment, the locking detection device is an induction switch, where the induction switch is a Hall switch or an optoelectronic switch or an inductive proximity switch. The locking detection device, the traveling drive mechanism 1, and the winding and unwinding assembly are all electrically connected to the control device, and the control device is installed on the connecting frame 2. In this embodiment, the induction switch is a Hall switch. The Hall switch includes a magnetic member and a Hall inductor. The magnetic member is disposed on the positioning structure 41 of the hanging box 4, and the Hall inductor is disposed on the second support member and corresponds to the magnetic member. When the latch pin 61 clamps the clamping portion of the positioning structure 41, electromagnetic induction occurs through the combination of the Hall sensor and the magnetic member, and an induction signal is output to the control device, so that the control device determines that the hanging box 4 is fixed on the connecting frame 2. The control device is configured as a control box 3. In this embodiment, the control box 3 is installed inside the connecting frame 2. In this embodiment, the control device is a cloud technology network control system, and it can also be a common control device or a PLC control system. The control device of the shuttle is also disclosed in the Chinese utility model patent with the authorization announcement number CN207264125U and the name of the shuttle and its control device. The specific structural components of the control box 3 are not described in detail in this embodiment.

[0044] Preferably, at least one side of the positioning structure 41 is provided with a first guiding surface 41a for guiding the positioning structure 41 to be inserted into the clamping groove 22b. In this embodiment, the first guiding surface 41a is a conical surface. Further, a second guiding surface 61a adapted to the first guiding surface 41a is provided at the second end of the latch pin 61. In this embodiment, the second guiding surface 61a is an inclined surface. When the positioning structure 41 enters the clamping groove 22b, the first guiding surface 41a on the positioning structure 41 at the top of the hanging box 4 pushes open the second guiding surface 61a of the latch pin 61, and then locks, and the lifting drive motor 71 stops operating through the monitoring device and the control device provided in the clamping groove 22b.

[0045] In addition, in this embodiment, the traveling driving mechanism 1 is installed on the erected low-altitude transportation network. The traveling driving mechanism 1 includes a driving wheel and a lifting driving motor 71 for driving the driving wheel to rotate. The driving wheel is in direct contact with the steel cable or rail of the transportation network, and the shuttle can move by rotating the driving wheel. Since the traveling driving mechanism 1 of the shuttle is a mature prior art, and the traveling driving mechanism 1 of the shuttle is also disclosed in the patent document of the Chinese invention patent application with the application publication number CN107839697A, the name of the shuttle driving mechanism, the shuttle and the cableway system, therefore, the specific structure of the traveling driving mechanism 1 will not be described in detail in this embodiment. In this embodiment, a suspension arm is fixed on the traveling driving mechanism 1, and the connecting frame 2 is connected to the bottom of the suspension arm. Specifically, a damping mechanism 5 is installed on the connecting frame 2, and the damping mechanism 5 is rotatably assembled with the suspension arm.

[0046] Preferably, the cableway transportation shuttle further includes a damping mechanism 5 provided at the top of the connecting frame 2, and the connecting frame 2 is connected to the traveling driving mechanism 1 through the damping mechanism 5. Among them, the specific structure of the damping mechanism 5 is a mature prior art, and the structure of the damping mechanism 5 is also disclosed in the patent document of the Chinese invention patent application with the application publication number CN110789542A, the name of an intelligent logistics shuttle. Therefore, the specific structure of the traveling driving mechanism 1 will not be described in detail in this embodiment. During the transportation of the shuttle, due to the unevenness of the steel cable or rail, the traveling driving mechanism 1 will shake, which will drive the suspension arm to shake. This kind of shake can be further divided into swing and up-and-down vibration. When swinging, since the suspension arm is rotatably assembled on the damping mechanism 5, the suspension arm itself swings, while the hanging box 4 and the connecting frame 2 will be in a relatively stable state under the action of gravity, thus ensuring the stability of transportation. In addition, when vibrating up and down, the suspension arm will directly act on the damping mechanism 5, and the acting force transmitted to the rotating shaft and the fixed seat will be slowed down by the damping spring, thereby reducing the amplitude of the up-and-down vibration of the hanging box 4 and further ensuring the stability of transportation.

[0047] The working process of the present invention is as follows: During installation, first load the goods to be transported into the hanging box 4. When it is necessary to raise the hanging box 4, the lifting drive motor 71 rotates forward, the worm 72 drives the first gear 74 to rotate, the first gear 74 drives the second gear 75 to rotate, and the baffle 6 is pushed in by the rotational cooperation of the threaded hole of the baffle 6 and the screw part of the connecting shaft 73. Then, the first return spring 77 and the baffle 6 act together to insert the bolt 61 into the clamping groove 22b. Since the thread of the screw part of the connecting shaft 73 has a set lead, when the threaded hole of the baffle 6 completely passes through the end of the lead inside the screw part, the screw part disengages from the thread and rotates idly. At the same time, the other end of the connecting shaft 73 keeps the threaded hole of the baffle 6 in contact with the screw part under the action of the second return spring 78, so as to quickly switch when the screw part is reversed. Meanwhile, the worm 72 drives the rotating shaft 76 to rotate through the worm wheel 79. When the rotating shaft 76 rotates forward, the rotating shaft 76 winds up the towing rope 8, thereby lifting the hanging box 4 until the positioning structure 41 at the top of the hanging box 4 slides into the clamping groove 22b. The first guiding surface 41a on the positioning structure 41 pushes open the second guiding surface 61a of the bolt 61 and then locks, and the lifting drive motor 71 stops operating through the monitoring device and the control device.

[0048] When it is necessary to lower the hanging box 4, the lifting drive motor 71 rotates in reverse, the worm 72 drives the first gear 74 to rotate, the first gear 74 drives the second gear 75 to rotate, and the baffle 6 is pushed out by the rotational cooperation of the threaded hole of the baffle 6 and the screw part of the connecting shaft 73. Then, the baffle 6 drives the bolt 61 to pull out of the clamping groove 22b against the elastic force and friction of the first return spring 77. Since the screw part of the connecting shaft 73 has a set lead, when the threaded hole of the baffle 6 passes through the end of the lead outside the screw part of the connecting shaft 73, the threaded hole of the baffle 6 is completely disengaged from the screw part of the connecting shaft 73 and rotates idly. Through the force of the bolt 61 and the first return spring 77, the threaded hole of the baffle 6 is kept in contact with the screw part of the connecting shaft 73, so as to quickly switch when the screw part rotates forward. At this time, the hanging box 4 is unlocked, and the lifting drive motor 71 drives the worm 72 to drive the rotating shaft 76 to rotate through the worm wheel 79. The rotating shaft 76 rotates in the reverse direction to release the towing rope 8. The length of the towing rope 8 released and lowered is proportional to the number of turns of the towing rope 8 wound around the rotating shaft 76 and the number of turns of the lifting drive motor 71 rotating. After the lifting drive motor 71 completes the specified number of rotating turns, the control device controls the lifting drive motor 71 to stop rotating. Under the action of gravity, the hanging box 4 descends to the distance of the length of the towing rope 8 released. Specifically, a preset height for the hanging box 4 to descend, that is, the length of the towing rope released and lowered, can be set for the control device. Then, the control device calculates the corresponding number of rotating turns of the lifting drive motor 71 and the number of turns that the towing rope 8 needs to be lowered on the rotating shaft 76 and starts to operate, so that the hanging box 4 descends to the preset height.

[0049] During the transportation of the shuttle, due to the unevenness of the steel cable or the rail, the walking drive mechanism 1 will shake, which will drive the suspension arm to shake. This kind of shake can be further divided into swing and up-and-down vibration. When swinging, since the suspension arm is rotationally assembled on the shock absorption mechanism 5, the suspension arm itself swings, while the hanging box 4 and the connecting frame 2 will be in a relatively stable state under the action of gravity, thus ensuring the stability of transportation. In addition, when vibrating up and down, the suspension arm will directly act on the shock absorption mechanism 5, and the force transmitted to the rotating shaft and the fixed seat will be reduced by the shock absorption spring, thereby reducing the amplitude of the up-and-down vibration of the hanging box 4 and further ensuring the stability of transportation.

[0050] In summary, the embodiment of the present invention provides a cableway transportation shuttle. The cableway transportation shuttle connects the hanging box 4 and the connecting frame 2 through the traction rope 8. The connecting frame 2 is provided with a winding and unwinding assembly capable of winding or releasing the traction rope 8, so that the length of the traction rope 8 can be adjusted through the winding and unwinding assembly, thereby adjusting the relative position between the hanging box 4 and the connecting frame 2, enabling the height of the hanging box 4 of the shuttle to be adjusted quickly and conveniently, enabling the operator to touch the hanging box 4, thus facilitating the installation and disassembly of the hanging box 4, and being able to stop at any time for loading and unloading goods, avoiding the problem that the shuttle in the prior art must load and unload goods at a professional logistics base and cannot meet the application scenario of loading and unloading goods at any stop.

[0051] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "top", "bottom", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0052] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
