Description

Technical Field

[0001] The present application relates to the field of logistics technology, and in particular to a rail-mounted lifting and reaching telescopic platform. Background Art

[0002] At present, the shelves in storage warehouses have different placement positions according to different goods. Among them, high-rise shelves are widely used, which makes full use of the warehouse space. However, because the goods on the high-rise shelves are at a higher position, it is more troublesome for workers to pick up and put the goods, and they need to use a lifting platform to lift and lower them. The existing lifting platforms are all ground rail structures, and workers need to stand on the lifting platforms to pick up goods during operation. Since the center of gravity of the lifting platform becomes higher after it rises, the lifting platform is unstable as a whole, which poses a risk of tipping over and cannot guarantee the safety of the workers. In addition, in order to place more shelves in a certain space, the distance between the shelves is designed to be able to be accommodated by only one lifting platform. This will cause multiple workers to pick up goods from the same shelf. The workers and the lifting platform cannot work in parallel and can only pick up goods individually in order.

[0034] See also Figure 1 and Figure 2In this embodiment, the hanging rail type lifting and reaching telescopic platform includes a guide rail 100, a walking mechanism 200, a first telescopic mechanism 300, a second telescopic mechanism 400 and a carrying mechanism 500; the guide rail 100 is used to be fixed on the top of the warehouse. Obviously, the guide rail 100 can also be installed on other buildings or infrastructure. The traveling mechanism 200 is connected to the guide rail 100 and is used to reciprocate relative to the guide rail 100 in the extension direction of the guide rail 100; the first telescopic mechanism 300 is simultaneously connected to the traveling mechanism 200 and the supporting mechanism 500, and the first telescopic mechanism 300 is used to telescope in the first direction 001 to drive the supporting mechanism 500 to rise and fall relative to the traveling mechanism 200 in the first direction 001; the second telescopic mechanism 400 is simultaneously connected to the traveling mechanism 200 and the supporting mechanism 500, and the second telescopic mechanism 400 is used to telescope in the second direction 002 to drive the supporting mechanism 500 to slide in the third direction 003 relative to the first telescopic mechanism 300; wherein, any two directions of the first direction 001, the second direction 002 and the third direction 003 have an angle.

[0035] The operating principle of the rail-type lifting and inserting telescopic platform provided in this embodiment is as follows:

[0036] Please combine Figure 1 、 Figure 2 and Figure 7When it is necessary to remove goods from a designated location on the shelf, the traveling mechanism 200 is activated, driving the first telescopic mechanism 300, the second telescopic mechanism 400, and the supporting mechanism 500 to move relative to the guide rail 100. When the supporting mechanism 500 moves to the designated location, the first telescopic mechanism 300 is activated, driving the supporting mechanism 500 to move up and down, so that the supporting mechanism 500 moves to a height corresponding to the goods. Then, the second telescopic mechanism 400 is activated. Since the telescopic direction of the second telescopic mechanism 400 is at an angle to the telescopic direction of the first telescopic mechanism 300, the second telescopic mechanism 400 can drive the supporting mechanism 500 to move in the third direction 003 relative to the first telescopic mechanism 300 during its extension, so that the supporting mechanism 500 can penetrate into the shelf and be located below the designated goods. Then, after the goods leave the shelf, they can directly fall onto the supporting mechanism 500, completing the retrieval process. Of course, after the goods are retrieved, the first telescopic mechanism 300 and the second telescopic mechanism 400 are operated. The two mechanisms cooperate to move the load-bearing mechanism 500 to the set position, and the goods are then removed from the load-bearing mechanism 500. The entire retrieval process is highly automated, eliminating the need for workers to stand on the load-bearing mechanism 500 to retrieve goods. This improves the existing practice of workers standing on a platform and enhances worker safety. Furthermore, the platform rationally utilizes the space above the warehouse. While the platform is retrieving goods, workers can retrieve goods from other locations on the shelf at the bottom of the platform. This eliminates interference with other workspaces, thereby improving space utilization and operational efficiency, and has promising application prospects.

[0037] Please combine Figure 1 and Figure 2 In this embodiment, the rail-mounted lifting and retractable platform optionally further includes a locking mechanism 600 and a guide mechanism 700. The locking mechanism 600 locks the traveling mechanism 200 and the guide rail 100 when the supporting mechanism 500 is in a set position, thereby improving stability and safety during the pickup process. The guide mechanism 700 guides the supporting mechanism 500, thereby ensuring greater stability and reliability during telescopic or retractable movements.

[0038] In this embodiment, the guide rail 100 can be optionally configured as an I-beam. Specifically, the guide rail 100 is a strip-shaped member having two assembly surfaces disposed opposite to each other, each of which is provided with a guide groove 110 , which is a rectangular groove and is mirror-symmetrically disposed.

[0039] Please combine Figure 3Optionally, the walking mechanism 200 includes a base 210, a first motor, a driving wheel 220, and a driven wheel 230. The first motor is disposed on the base 210, and the driving wheel 220 and the driven wheel 230 are both rotatably connected to the base 210. The output shaft of the first motor is connected to the driving wheel 220 to drive the driving wheel 220 to rotate, thereby causing the walking mechanism 200 to slide back and forth as a whole relative to the guide rail 100. The driving wheel 220 and the driven wheel 230 are respectively embedded in the two guide grooves 110, so that the walking mechanism 200 is not easily dislodged from the guide rail 100. It should be understood that the number of driven wheels 230 can be multiple, and driven wheels 230 can be set in both guide grooves 110 to improve stability.

[0040] Please combine Figure 3 Furthermore, four clamping arms 240 are provided on the base 210, and the four clamping arms 240 are distributed at the four corners of the same rectangle. Each clamping arm 240 has a clamping hole 241, and each clamping arm 240 is provided with a bolt. By tightening the bolt, the opening of the clamping hole 241 can be adjusted, thereby clamping the component located within the clamping hole 241. It should be noted that the four clamping arms 240 are divided into two groups, each group including two clamping arms 240. When the walking mechanism 200 is assembled with the guide rail 100, the two groups of clamping arms 240 are located on opposite sides of the guide rail 100.

[0041] Furthermore, the bottom of the base 210 is provided with a clearance hole 211 for inserting certain components of the locking mechanism 600, thereby enabling the locking mechanism 600 to cooperate with the guide rail 100 to achieve locking or unlocking functions. The clearance hole 211 can be a round hole or a square hole. Furthermore, two positioning holes 212 are provided on the outside of the clearance hole 211, and the two positioning holes 212 are arranged in a mirror-symmetrical manner.

[0042] Please combine Figure 2 and Figure 4In this embodiment, the locking mechanism 600 includes a second motor 610, a lead screw 620, a nut 630, two connecting shafts 640, and a damping member 650. The housing of the second motor 610 is connected to the base 210. The output shaft of the second motor 610 is connected to the lead screw 620 via a coupling. The lead screw 620 extends in a first direction 001, and a portion of the lead screw 620 is inserted into the avoidance hole 211. The nut 630 is sleeved on the outside of the lead screw 620 and is threadedly connected to the lead screw 620. The damping member 650 and the nut 630 are fixedly connected via two connecting shafts 640. The damping member 650 is located between the guide rail 100 and the base 210. At the same time, the two connecting shafts 640 are respectively inserted into two positioning holes 212 on the base 210. In this way, the damping member 650 and the nut 630 are relatively fixed to the base 210 in the circumferential direction of the lead screw 620. When the second motor 610 is started, the output shaft of the second motor 610 drives the lead screw 620 to rotate, while the nut 630 and the damping member 650 do not rotate with the lead screw 620. This allows the nut 630 and the damping member 650 to slide axially relative to the lead screw 620, thereby switching the damping member 650 between a locked state and an unlocked state. In other words, when the damping member 650 abuts the bottom of the guide rail 100, the damping member 650 is in a locked state, and the damping member 650 can restrict the movement of the running mechanism 200 relative to the guide rail 100. To release the locked state, even if the damping member 650 is in the unlocked state, the second motor 610 is continued to be operated to rotate it, and the nut 630 drives the damping member 650 away from the guide rail 100, separating the damping member 650 from the guide rail 100, and allowing the running mechanism 200 to move relative to the guide rail 100.

[0043] It should be noted that the damping member 650 can be configured as a rubber member, or part of the damping member 650 can be configured as a rubber layer. The rubber member or rubber layer can increase the friction between the damping member 650 and the guide rail 100, thereby improving the braking effect.

[0044] Please combine Figure 4In this embodiment, the first telescopic mechanism 300 optionally includes a scissor mechanism 310, a top plate 320, and a bottom plate 330. The top plate 320 is provided with four connecting posts 340, which are respectively inserted into the clamping holes 241 of the four clamping arms 240. The clamping arms 240 are then locked to the connecting posts 340 via bolts, thereby achieving a fixed connection between the base 210 and the top plate 320. One end of the scissor mechanism 310 is connected to the top plate 320, and the other end of the scissor mechanism 310 is connected to the bottom plate 330. The scissor mechanism 310 is used to drive the bottom plate 330 to move relative to the top plate 320 in a first direction 001, that is, to achieve the lifting and lowering movement of the bottom plate 330. The supporting mechanism 500 is connected to the bottom plate 330. It should be understood that the scissor mechanism 310 can adopt existing well-known technologies and will not be described in detail in this embodiment. For example, the scissors mechanism 310 includes a scissors frame and a telescopic cylinder. The two ends of the scissors frame are respectively connected to the top plate 320 and the bottom plate 330. The cylinder body of the telescopic cylinder is connected to the top plate 320, and the piston rod is connected to the scissors frame. The telescopic movement of the telescopic cylinder drives the scissors frame to extend and retract, thereby realizing the lifting and lowering of the bottom plate 330 relative to the top plate 320.

[0045] It should be understood that the telescopic cylinder can be a pneumatic cylinder or a hydraulic cylinder, etc.

[0046] Please combine Figure 1 and Figure 7 In this embodiment, optionally, the guide mechanism 700 includes a guide sleeve 710 and a guide post 720, one end of the guide sleeve 710 is connected to the top plate 320, the guide post 720 is inserted into the guide sleeve 710 and the two are slidably matched, one end of the guide post 720 is connected to the bottom plate 330, and the number of the guide mechanism 700 can be four, respectively located around the scissors mechanism 310, which can improve the stability of the bottom plate 330 when it is raised and lowered. It should be understood that the guide post 720 and the guide sleeve 710 can be configured as linear bearings. Alternatively, in other embodiments, the guide post 720 is connected to the top plate 320, and the guide sleeve 710 is connected to the bottom plate 330, which can guide the bottom plate 330 to slide relative to the top plate 320 in the first direction 001.

[0047] In this embodiment, it should be noted that the second telescopic mechanism 400 can be configured as a pneumatic cylinder, a hydraulic cylinder, or an electric push rod. For example, in this embodiment, the second telescopic mechanism is a pneumatic cylinder, whose cylinder body is rotatably connected to the top plate 320, and whose piston rod is rotatably connected to the supporting mechanism 500. In other embodiments, the second telescopic mechanism 400 can be configured as a multi-stage telescopic mechanism, which has a larger travel range and a wider range of adaptability.

[0048] Please combine Figure 5 and Figure 6In this embodiment, the supporting mechanism 500 optionally includes a first sliding plate 510 and a second sliding plate 520. The first sliding plate 510 is slidably connected to the bottom plate 330 in the third direction 003 via a first sliding pair 530, and the two are relatively fixed in the first direction 001. The second sliding plate 520 is slidably connected to the first sliding plate 510 in the third direction 003 via a second sliding pair 540, and the two are relatively fixed in the first direction 001. The second telescopic mechanism 400 is rotatably connected to both the top plate 320 and the second sliding plate 520. That is, when the bottom plate 330 is raised or lowered, it can drive the first sliding plate 510 and the second sliding plate 520 to rise or fall together. When the second telescopic mechanism is extended or retracted, it can drive the second sliding plate 520 to slide relative to the first sliding plate 510 and the first sliding plate 510 to slide relative to the bottom plate 330. The first sliding pair 530 and the second sliding pair 540 can both be configured as linear bearings.

[0049] Furthermore, a first limit block 331 is provided on the base plate 330, a second limit block 511 and a third limit block 513 are provided on the first sliding plate 510, and a fourth limit block 521 is provided on the second sliding plate 520. The first limit block 331 and the second limit block 511 are arranged at intervals in the third direction 003, and the first limit block 331 is located on the sliding path of the second limit block 511 in the third direction 003, that is, when the first sliding plate 510 slides relative to the base plate 330, the second limit block 511 can abut against the first limit block 331, thereby preventing the first sliding plate 510 from separating from the base plate 330. Similarly, the third limiting block 513 and the fourth limiting block 521 are spaced apart in the third direction 003, and the first limiting block 331 and the third limiting block 513 are located on the same side, and the second limiting block 511 and the fourth limiting block 521 are located on the same side. When the second sliding plate 520 slides relative to the first sliding plate 510, the fourth limiting block 521 can abut against the third limiting block 513, thereby preventing the second sliding plate 520 from sliding off the first sliding plate 510. It should be understood that the first limiting block 331 and the second limiting block 511 constitute a first anti-slip assembly, and the third limiting block 513 and the fourth limiting block 521 constitute a second anti-slip assembly.

[0050] During operation of the overhead rail lifting and telescopic platform provided in this embodiment, the traveling mechanism 200 drives the supporting mechanism 500 to a set shelf position. The first telescopic mechanism then drives the supporting mechanism 500 up and down to the set height of the corresponding shelf. At this point, the second motor 610 is activated, causing the damping member 650 to abut against the guide rail 100, thereby locking the guide rail 100 and the traveling mechanism 200. The traveling mechanism 200 and the supporting mechanism 500 do not slide relative to the guide rail 100, facilitating subsequent cargo retrieval. The second telescopic mechanism 400 is then activated and extended. Since the bottom plate 330 does not continue to descend, the second telescopic mechanism 400 can drive the second sliding plate 520 to slide out of the first sliding plate 510. The first sliding plate 510 can then slide out of the bottom plate 330, allowing the second sliding plate 520 to slide under the cargo, thereby receiving the cargo. During the extension of the second telescopic mechanism 400, the second telescopic mechanism 400 will rotate relative to the top plate 320, that is, the second direction 002 will continue to change. It can be understood that during the extension of the second telescopic mechanism 400, the angle between the second direction 002 and the vertical direction will gradually increase, and when the second telescopic mechanism 400 is retracted and reset, the angle between the second direction 002 and the vertical direction will gradually decrease.

[0051] It should be understood that, in this embodiment, the first direction 001 can be understood as a vertical direction, the second direction 002 has an angle with the vertical direction, and the third direction 003 can be understood as a horizontal direction.

[0052] The rail-mounted lifting and retractable platform provided in this embodiment allows workers to access goods without having to stand on the load-bearing assembly during operation, thereby avoiding potential accidents. Furthermore, the retractable platform rationally utilizes the overhead space in the warehouse, allowing other workers to access goods from below while the workspace is being worked on, without disrupting the workspace and improving work efficiency.

[0053] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
