Description

Technical Field

[0001] This invention relates to the field of material handling technology, and more particularly to a material conveying device. Background Technology

[0002] In engineering construction, for high-rise or deep-well operations, it is necessary to use lifting devices or manual labor to transport materials between two heights. Currently, most of the products on the market use ladder-guided conveyor devices to lift materials. The hopper is installed on a pulley, and the hopper moves along the guide ladder with the pulley. However, the existing hoppers cannot tilt, so they cannot automatically unload raw materials such as cement and sand, requiring manual assistance, which is labor-intensive. Furthermore, they cannot automatically adjust the unloading angle for bricks, base plates, wood, pipes, etc., making unloading inconvenient. Summary of the Invention

[0072] One embodiment of the present invention, in conjunction with Figures 1 to 19 As shown, a material conveying device is provided.

[0073] According to one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the material conveying device includes a guide ladder 1, a trolley 2, a hopper 3, a tilting mechanism 4, and a drive mechanism 5. The trolley 2 is slidably mounted on the guide ladder 1, and the hopper 3 is mounted on the trolley 2 and moves with the trolley 2. The tilting mechanism 4 connects the trolley 2 and the hopper 3. The drive mechanism 5 is connected to the tilting mechanism 4 so that when the hopper 3 moves to the top of the guide ladder 1, the drive mechanism 4 drives the hopper 3 to tilt relative to the trolley 2.

[0074] It is understood that in this embodiment, when the trolley 2 drives the hopper 3 to the top of the guide ladder 1, the drive mechanism 5 provides power to the tilting mechanism 4, driving the tilting mechanism 4 to tilt, so that the hopper 3 tilts relative to the trolley 2, thereby tilting the hopper 3 at a certain angle. By tilting the hopper 3, the material in the hopper 3 is gradually poured out, realizing automatic unloading, or adjusting the hopper 3 to a suitable unloading angle to facilitate manual unloading, reducing the workload, improving the unloading efficiency, and expanding the applicability of the material conveying device.

[0075] According to one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the flipping mechanism 4 includes a support frame 41 and a rotating frame 42. The support frame 41 includes a front end 411 and a rear end 412. The rear end 412 is slidably connected to the trolley 2. The driving mechanism 5 is adapted to drive the rear end 412 to slide along the trolley 2. The rotating frame 42 is used to fix the hopper 3. The rotating frame 42 is rotatably connected to the front end 411, and one end of the rotating frame 42 is rotatably connected to the trolley 2. When the rear end 412 slides along the trolley 2, the front end 411 pushes the rotating frame 42 to rotate relative to the trolley 2, so that the hopper 3 flips relative to the trolley 2 in the first direction.

[0076] It should be noted that the first direction is Figure 1 In the clockwise direction, the rotating frame 42 in this embodiment can be integrated on the hopper 3 to improve the structural strength of the hopper 3. Alternatively, the rotating frame 42 can be omitted in the flipping mechanism 4, and the trolley 2 can be directly connected to the hopper 3 through the support frame 41. The front end 411 of the support frame 41 can directly push the hopper 3 to flip relative to the trolley 2. As long as the rear end 412 of the support frame 41 can slide along the trolley 2, the front end 411 can push the hopper 3 to flip relative to the trolley 2.

[0077] According to one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, a first elastic element 21 is provided on the trolley 2. One end of the first elastic element 21 is connected to the trolley 2, and the other end is connected to the tilting mechanism 4 so that after the driving mechanism 5 stops driving, it pulls the hopper 3 to rotate in the second direction, which is opposite to the first direction.

[0078] In this embodiment, after unloading is completed, the hopper 3 will rotate along the second direction under the action of gravity. Furthermore, in order to ensure that the hopper 3 can be completely reset after unloading, the trolley 2 is provided with a first elastic element 21 connecting the trolley 2 and the tilting mechanism 4, so that the tilting mechanism 4 can automatically return to its original position after the driving mechanism 5 stops driving, thus resetting the hopper 3.

[0079] In some embodiments, reference Figure 1 and Figure 2 As shown, the two ends of the first elastic element 21 are connected to the trolley 2 and the front end 411 of the support frame 41. After the driving mechanism 5 stops driving, the first elastic element 21 pulls the front end 411 of the support frame 41 to slide, thereby rotating the hopper 3 to its original position in the second direction. In other embodiments, the two ends of the first elastic element 21 may also be connected to the trolley 2 and the rear end 412 of the support frame 41, or the two ends of the first elastic element 21 may be connected to the trolley 2 and the rotating frame 42, or the two ends of the first elastic element 21 may be connected to the trolley 2 and the hopper 3, as long as it can achieve the goal of the first elastic element 21 pulling the hopper 3 to its original position after the driving mechanism 5 stops driving.

[0080] According to one embodiment of the present invention, such as Figure 2 , Figure 3 and Figure 4 As shown, the trolley 2 is equipped with a hook 22, and the drive mechanism 5 drives the trolley 2 to slide via a steel wire rope 51. The material conveying device also includes a rope guide assembly, which includes a first pulley block 61, a second pulley block 62, and a third pulley block 63. The first pulley block 61 is installed on the top of the guide ladder 1, combined with... Figure 5 , Figure 6 and Figure 7 As shown, the second pulley block 62 is installed at the rear end 412 of the support frame 41, including the first pulley 621 and the second pulley 622 arranged coaxially. The third pulley block 63 is installed on the top of the trolley 2. The wire rope 51 is adapted to be connected to the hook 22 after being guided by the first pulley block 61, the first pulley 621, the third pulley block 63 and the second pulley 622 in sequence.

[0081] In this embodiment, one end of the wire rope 51 is connected to the drive mechanism 5, and the other end is connected to the hook 22 on the trolley 2. The wire rope 51 drives the trolley 2 to slide along the guide ladder 1. A trigger plate can be provided at the top of the guide ladder 1. When the trolley 2 moves to the top of the guide ladder 1, the trigger plate is triggered to cut off the running circuit of the trolley 2, so that the trolley 2 stops moving upward. Since the second pulley group 62 is installed at the rear end 412 of the support frame 41, when the drive mechanism 5 continues to drive the wire rope 51, it will pull the rear end 412 of the support frame 41 to slide along the trolley 2, thereby causing the front end 411 of the support frame 41 to push the rotating frame 42 to rotate, so that the hopper 3 flips relative to the trolley 2.

[0082] It is understood that the trigger plate cutoff circuit can be implemented by means of mechanical switches, electromagnetic relays, intelligent sensors or microcontrollers, etc., and this embodiment does not specifically limit it. The arrangement of the wire rope 51 in this embodiment allows the drive mechanism 5 to both drive the trolley 2 to slide along the guide ladder 1 and drive the tilting mechanism 4 to tilt the hopper 3 relative to the trolley 2 when the trolley 2 moves to the top of the guide ladder 1. No additional tilting power structure is required, the structure is simple and the reliability is high.

[0083] According to one embodiment of the present invention, in combination Figure 1 , Figure 8 and Figure 9 As shown, a locking rod 24 is provided on the trolley 2, and a locking hole 421 is provided on the rotating frame 42. The locking rod 24 is adapted to be inserted into or pulled out of the locking hole 421 so that the rotating frame 42 can switch between a first locked state and a first unlocked state. In the first locked state, the rotating frame 42 is fixed relative to the trolley 2. In the first unlocked state, the rotating frame 42 is adapted to rotate around the trolley 2 so that the hopper 3 flips relative to the trolley 2.

[0084] It is understood that in this embodiment, the locking and unlocking of the rotating frame 42 can be achieved by the cooperation of the locking rod 24 and the locking hole 421. During the process of the trolley 2 sliding along the guide ladder 1, the locking rod 24 is inserted into the locking hole 421. At this time, the rotating frame 42 and the trolley 2 are relatively fixed, and the rotating frame 42 cannot rotate. When the trolley 2 reaches the top of the guide ladder 1, the locking rod 24 can be pulled out of the locking hole 421. At this time, the rotating frame 42 switches from the first locked state to the first unlocked state, and the rotating frame 42 can rotate relative to the trolley 2 to flip the hopper 3.

[0085] According to one embodiment of the present invention, such as Figure 11 and Figure 12 As shown, a locking hook 23 is provided on the trolley 2, and a locking hook seat 11 is provided at a preset position on the guide ladder 1. The locking hook 23 is adapted to engage with the locking hook seat 11 when the trolley 2 moves to the top of the guide ladder 1, so that the trolley 2 is held at the top of the guide ladder 1.

[0086] In this embodiment, reference Figure 11 and Figure 12 When the trolley 2 moves to the top of the guide ladder 1, the locking hook 23 can engage with the locking hook seat 11 at the top of the guide ladder 1, hanging the trolley 2 at the top of the guide ladder 1. This prevents the trolley 2 from falling during the rotation of the hopper 3 relative to it, thus improving the safety performance of the material conveying device. Optionally, a locking hook 23 is provided on one side of the trolley 2, or alternatively, locking hooks 23 are provided on both sides of the trolley 2, to better hold the trolley 2 at the top of the guide ladder 1. Furthermore, the locking hooks 23 and locking hook seats 11 are arranged correspondingly, and their number can be one or more. Users can set this according to their needs, and this embodiment does not impose specific limitations on this.

[0087] Understandably, in one embodiment, when the trolley 2 moves to the top of the guide ladder 1, the operator can manually switch the rotating frame 42 to the first unlocked state, so that the rotating frame 42 can rotate and drive the hopper 3 to flip. In another embodiment, when the trolley 2 moves to the top of the guide ladder 1, the rotating frame 42 can automatically switch to the first unlocked state, realizing the automatic unlocking of the rotating frame 42 without manual operation, which is convenient and quick.

[0088] Specifically, such as Figure 8 and Figure 9 As shown, one method for automatically unlocking the rotating frame 42 is as follows: the locking hook 23 is connected to the locking rod 24 via the rotating rod 25. One end of the rotating rod 25 is rotatably connected to the locking rod 24, and the other end of the rotating rod 25 is connected to the locking hook 23. The other end of the rotating rod 25 is rotatably connected to the trolley 2. During the process of the locking hook 23 contacting the locking hook seat 11 and engaging with it, the locking hook 23 rotates relative to the trolley 2 and drives the locking rod 24 to move to pull out the locking hole 421, thus switching the rotating frame 42 to the first unlocked state.

[0089] In this embodiment, during the movement of the trolley 2 toward the top of the guide ladder 1, since the locking hook seat 11 is set in the direction of movement of the locking hook 23, the locking hook 23 gradually contacts and engages with the locking hook seat 11. During this process, the locking hook 23 will rotate relative to the trolley 2 at a certain angle. When the locking hook 23 rotates, it drives the rotating rod 25 to rotate synchronously, causing the locking rod 24 connected to the rotating rod 25 to also move. After the locking rod 24 moves a certain distance, it pulls out of the locking hole 421 and switches the rotating frame 42 to the first unlocking state, thus realizing the automatic unlocking of the rotating frame 42 after the trolley 2 moves to the top of the guide ladder 1.

[0090] Furthermore, after the material in hopper 3 is unloaded and hopper 3 rotates to its reset position in the second direction, the rotating frame 42 switches from the first unlocked state to the first locked state, fixing the rotating frame 42 relative to the trolley 2 to prevent hopper 3 from tipping over during transportation. It is understood that the switching of the rotating frame 42 to the first locked state can also be achieved through manual operation or automatic locking.

[0091] According to one embodiment of the present invention, after the hopper 3 is reset, the rotating frame 42 automatically switches to the first locking state, fixing the rotating frame 42 relative to the trolley 2. In this embodiment, as shown... Figure 8 , Figure 9 and Figure 15As shown, the material conveying device is equipped with a locking component 26 to switch the rotating frame 42 from the first unlocked state to the first locked state. The locking component 26 includes a locking block 261, a first connecting rod 262 and a second connecting rod 263. The locking block 261 is disposed on the rotating frame 42. One end of the first connecting rod 262 is rotatably disposed on the trolley 2. One end of the second connecting rod 263 is rotatably connected to the other end of the first connecting rod 262. The other end of the second connecting rod 263 is rotatably connected to the locking rod 24. When the hopper 3 rotates along the second direction, the locking block 261 abuts against the first connecting rod 262 or the second connecting rod 263 to make the first connecting rod 262 or the second connecting rod 263 rotate, pull the locking rod 24 to insert into the locking hole 421, and switch the rotating frame 42 to the first locked state.

[0092] It is understandable that the rotating frame 42 is equipped with a locking block 261. During the reset process of the hopper 3, the rotating frame 42 rotates relative to the trolley 2 in the second direction. The rotation of the rotating frame 42 drives the locking block 261 to rotate. The first connecting rod 262 or the second connecting rod 263 is set on the rotation path of the locking block 261. When the locking block 261 moves, it contacts the first connecting rod 262 or the second connecting rod 263, causing the first connecting rod 262 or the second connecting rod 263 to rotate, thereby pulling the locking rod 24 to move. After the locking rod 24 moves to a certain distance, it inserts into the locking hole 421, so that the rotating frame 42 switches to the first locking state. The rotating frame 42 cannot rotate relative to the trolley 2, realizing the automatic locking of the rotating frame 42 after the hopper 3 is reset. No manual operation is required, which is convenient and quick.

[0093] According to one embodiment of the present invention, such as Figure 11 and Figure 12 As shown, the locking assembly 26 also includes a second elastic member 264. One end of the second elastic member 264 is connected to the second connecting rod 263, and the other end is connected to the trolley 2. In the first unlocked state, the second elastic member 264 is adapted to pull the second connecting rod 263 to keep the first connecting rod 262 and the second connecting rod 263 in a preset position, preventing the first connecting rod 262 and the second connecting rod 263 from rotating, so that the locking hook 23 is kept engaged with the locking hook seat 11, preventing the trolley 2 from falling down during the process of the hopper 3 flipping relative to the trolley 2, and improving the safety performance of the material conveying device.

[0094] According to one embodiment of the present invention, such as Figure 1 , Figure 9 and Figure 10As shown, the rotating frame 42 is provided with a mounting base 422, a pin 423, and a third elastic member 424. The mounting base 422 forms a first mounting wall 4221 and a second mounting wall 4222, both of which have mounting holes. The pin 423 is adapted to pass through the mounting hole to install the hopper 3 onto the mounting base 422. The third elastic member 424 is sleeved on the pin 423 and is located between the first mounting wall 4221 and the second mounting wall 4222. One end of the third elastic member 424 is connected to the pin 423 through a mounting pin 425, and the other end abuts against the second mounting wall 4222.

[0095] In this embodiment, the third elastic element 424 can be a spring, a sheet, or a soft rubber column, etc. One end of the third elastic element 424 is connected to the pin 423, and the other end abuts against the second mounting wall 4222, so that the pin 423 can be elastically reset after being released and remain inserted in the mounting hole. On the one hand, the pin 423 is automatically reset after the user releases it, and on the other hand, the pin 423 is always inserted into the mounting hole of the mounting base 422 to prevent it from falling off and to prevent the hopper 3 and the rotating frame 42 from separating.

[0096] According to one embodiment of the present invention, a gasket 426 is provided on the side of the mounting pin 425 away from the first mounting wall 4221.

[0097] It is understandable that by providing a washer 426 on the side of the mounting pin 425 away from the first mounting wall 4221, the washer 426 is driven to squeeze the third elastic element 424 when the pin 423 is pulled out, thereby increasing the contact area of ​​the third elastic element 424 when it contracts, making it easier and less strenuous to pull out the pin 423. Optionally, the washer 426 can be provided separately or integrally formed with the pin 423; this embodiment does not impose a specific limitation.

[0098] According to one embodiment of the present invention, in combination Figure 1 , Figure 14 and Figure 17As shown, a guide assembly 28 is provided on the trolley 2. The guide assembly 28 is slidably connected to the guide ladder 1. The trolley 2 slides on the guide ladder 1 through the guide assembly 28, reducing sliding friction and facilitating the sliding of the trolley 2 on the guide ladder 1. Optionally, the guide assembly 28 includes a mounting frame 281, a pressure roller 282, a side roller 283, and a hook wheel 284. The mounting frame 281 is mounted on the trolley 2. The pressure roller 282 is rotatably mounted on the mounting frame 281 and slides along the upper surface of the guide ladder 1. The side roller 283 is rotatably mounted on the mounting frame 281 and located on the outer side of the guide ladder 1, sliding along the outer side of the guide ladder 1. The hook wheel 284 is rotatably mounted on the mounting frame 281 and located on the inner side of the guide ladder 1, sliding along the inner side of the guide ladder 1. In this embodiment, the pressure roller 282, the side roller 283, and the hook wheel 284 slide along different surfaces of the guide ladder 1, respectively serving to bear pressure, provide lateral guidance, and prevent the trolley 2 from detaching from the guide ladder 1.

[0099] According to one embodiment of the present invention, such as Figure 18 and Figure 19 As shown, the material conveying device also includes a tilting limit mechanism 7 and a controller. The tilting limit mechanism 7 includes a limit mounting plate 71, which is installed on the top of the guide ladder 1, a limit switch 72, which is installed on the limit mounting plate 71, and a limit trigger plate 73, which is installed on the tilting mechanism 4 or the hopper 3. When the hopper 3 tilts, it is adapted to drive the limit trigger plate 73 to trigger the limit switch 72, thereby controlling the drive mechanism 5 to stop driving.

[0100] It is understandable that, such as Figure 18 and Figure 19 As shown, the limit switch 72 can be installed on the rotating frame 42 and rotates with the rotating frame 42. In other embodiments, the limit switch 72 can also be installed on the hopper 3. In this embodiment, the limit switch 72 can consist of a mechanical contact and an electrical switch. When the limit trigger plate 73 contacts or approaches the mechanical contact, the contact will be pressured and change the state of the electrical switch, thereby outputting a corresponding signal. This signal can be used to control the start and stop of the drive mechanism 5, indicate the flipping angle of the hopper 3, or perform position feedback operations. By setting the limit switch 72 at the top of the guide ladder 1 and setting the position of the limit switch 72 according to the required flipping angle, the limit switch 72 is triggered when the hopper 3 flips to a preset angle, stopping the flipping of the hopper 3 and keeping the hopper 3 at the preset angle to achieve unloading. It is understood that the type of limit switch 72 can be contact or non-contact, and this embodiment does not make a specific limitation.

[0101] In some embodiments, the material conveying device also includes a sensor and a controller. The sensor is adapted to detect the tilting angle of the hopper 3, and the controller is connected to the sensor and the drive mechanism 5. The controller is adapted to control the drive mechanism 5 to drive or stop based on the tilting angle of the hopper 3. This allows for easy adjustment of the tilting angle of the hopper 3 according to different material types to achieve automatic unloading, or to adjust the hopper 3 to a suitable unloading angle for easy manual unloading, adapting to different working scenarios.

[0102] According to one embodiment of the present invention, such as Figure 2 As shown, a limit block 12 is provided at the top of the guide ladder 1 to restrict the trolley 2 from sliding out of the guide ladder 1, prevent the trolley 2 from falling off, and improve the safety performance of the material conveying device.

[0103] In some embodiments, the trolley 2 is equipped with a fall arrestor 27, which stops the trolley 2 and locks it on the track in the event of an accident such as the wire rope 51 breaking or the hook 22 connecting the wire rope 51 falling off, thus preventing the trolley 2 and hopper 3 from falling and causing a safety accident. (Reference) Figure 13 , Figure 16 and Figure 17 As shown, the fall arrestor assembly 27 includes a fixed base 271, a pull rod 272, a transmission component 273, a rotating shaft 274, a fourth elastic element 275, and a locking block 276. The fixed base 271 is mounted on the trolley 2. The middle part of the pull rod 272 is hinged to the fixed base 271. The pull rod 272 includes a first end and a second end. The first end is provided with a hook 22. One end of the transmission component 273 is connected to the second end. The rotating shaft 274 is connected to the other end of the transmission component 273. The movement of the transmission component 273 is adapted to drive the rotating shaft 274 to rotate. The fourth elastic element 275 is sleeved on the rotating shaft 274. One end of the fourth elastic element 275 is connected to the rotating shaft. 274. The other end of the fourth elastic element 275 is connected to the trolley 2. The locking block 276 is connected to the other end of the transmission element 273. The locking block 276 is adapted to switch between the second locking state and the second unlocking state. The wire rope 51 pulls the first end of the pull rod 272 to rotate in the first direction relative to the fixed seat 271, so that the transmission element 273 drives the locking block 276 away from the guide ladder 1, and switches the locking block 276 to the second unlocking state. The fourth elastic element 275 is adapted to pull the rotating shaft 274 to rotate, so that the locking block 276 abuts against the guide ladder 1, and switches the locking block 276 to the second locking state.

[0104] Understandably, the locking block 276 rotates around the center of the rotating shaft 274 under the drive of the transmission component 273. When the hook 22 is pulled by the wire rope 51, it drives the first end of the pull rod 272 to rotate. The pull rod 272 transmits the movement to the transmission component 273, which is rotatably connected to it. The transmission component 273 then transmits this movement to the rotating shaft 274, causing the rotating shaft 274 to rotate. This, in turn, causes the locking block 276 on the rotating shaft 274 to rotate away from the guide ladder 1. At this time, the locking block 276 does not contact the guide ladder 1, and the trolley 2 can slide smoothly along the guide ladder 1. When the wire rope... In the event of an accident such as breakage of 51 or detachment of hook 22, the fourth elastic element 275 pulls the rotating shaft 274 to rotate, causing the locking block 276 to rotate towards the guide ladder 1. This causes the locking block 276 to abut against the surface of the guide ladder 1. As the rotation of the locking block 276 increases, the locking block 276 and the surface of the guide ladder 1 become increasingly tighter, resulting in greater friction between the locking block 276 and the guide ladder 1. When the friction reaches a certain level, the trolley 2 will stop moving and lock onto the guide ladder 1, preventing the trolley 2 and hopper 3 from falling and ensuring the safe operation of the material conveying device.

[0105] An embodiment of the present invention provides a material conveying device, including a guide ladder 1, a trolley 2, a hopper 3, a tilting mechanism 4, and a drive mechanism 5. The trolley 2 is slidably disposed on the guide ladder 1, and the hopper 3 is disposed on the trolley 2 and moves with the trolley 2. The tilting mechanism 4 connects the trolley 2 and the hopper 3. The drive mechanism 5 is connected to the tilting mechanism 4 so that when the hopper 3 moves to the top of the guide ladder 1, the drive mechanism 4 drives the hopper 3 to tilt relative to the trolley 2 in a first direction. When the trolley 2 drives the hopper 3 to move to the top of the guide ladder 1, the drive mechanism 5 provides power to the tilting mechanism 4, driving the tilting mechanism 4 to tilt, so that the hopper 3 tilts relative to the trolley 2, thereby tilting the hopper 3 at a certain angle. By tilting the hopper 3, the material in the hopper 3 is gradually poured out, realizing automatic unloading, or adjusting the hopper 3 to a suitable unloading angle to facilitate manual unloading. This reduces labor intensity, improves unloading efficiency, and expands the applicability of the material conveying device.
