Description
Technical Field
[0001] This invention relates to the field of warehouse logistics, and more specifically, to a lifting machine with good safety performance that facilitates transportation. Background Technology
[0002] During the production of beer bottles, they need to be boxed and placed on shelves. However, some shelves in the warehouse are too high for manual placement, and they are also difficult to retrieve after placement, resulting in incomplete utilization of warehouse space. While dividing the warehouse into layers improves space utilization, it significantly reduces work efficiency. In this case, lifting machines are needed to transport beer bottles to heights that are not easily accessible by manual labor. However, due to mechanical aging and wear and tear of parts, the lifting platform may fall when lifting goods, damaging the goods on the platform and potentially injuring workers.

[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] (1) Through the installation of the box, buffer mechanism, and protection mechanism, the operation of the power unit raises the box to transport goods, allowing them to be stored in higher places or moved down from higher shelves. The protection mechanism can protect the box in case of power unit failure or malfunction, preventing the box from falling and being damaged. The buffer mechanism can cushion the goods inside the box, preventing damage to the goods due to impact and economic losses, thus improving the safety of the elevator. The slider in the second slide can provide auxiliary guidance for the box during movement, making the movement of the box smoother and more stable, and making the transport of goods safer. The design incorporates a spiral rod that rotates as the slider slides. When the slider slides normally, the spiral rod's rotation is insufficient to dislodge the locking block connected via the shaft, preventing contact between the locking block and the slot, allowing the spiral rod to rotate normally. However, when the box falls uncontrollably, the slider causes the spiral rod to rotate rapidly, and centrifugal force throws the locking block out, causing it to contact the slot and lock the spiral rod, preventing further sliding and protecting the box. The impact of the sudden stop is cushioned by a buffer mechanism to prevent damage to the goods. Furthermore, the spring and connecting parts allow the locking block to be pulled back after the box is repaired, separating it from the slot and allowing the spiral rod to continue rotating.
[0016] (2) Through the through hole on one side of the slider and the ball bearing one in contact with the screw rod, when the slider slides, the ball bearing one rolls in the groove of the screw rod, thereby driving the screw rod to rotate. When the screw rod is stuck and cannot rotate, the slider can be limited, thereby preventing the box from falling. The sliding rod can limit and guide the slider, making the slider smoother and more stable when sliding. The support platform can support the goods. The baffle and the spring piece in the groove of the box can support the support platform. When the box falls and stops suddenly, the elasticity of the baffle and the spring piece can buffer the support platform. The spring can further improve the buffering effect of the support platform and prevent the goods from being damaged due to the inertia of the sudden stop.
[0017] (3) By setting two motors and two connecting frames, the force on the box is more even when the motor drives the transmission mechanism to lift the box, so that the lifting effect is better and the pressure on the motor is reduced. The torque protection device can prevent the pressure of the other motor from rising sharply and causing damage after one motor fails, so that the box is separated from the motor when it falls, and the two motors are prevented from being damaged at the same time. By setting turntable one and turntable two, when the torque between the motor and the transmission mechanism increases, turntable two squeezes ball two and makes ball two slide into the circular groove, so that ball two separates from turntable two, thus disconnecting the connection between turntable one and turntable two, protecting the motor and preventing the motor from being damaged by overload. By setting rollers and rolling rollers, when the rollers rotate, the chain is connected to the box through the rolling rollers, so that the force on the box is always vertical, thus making the movement of the box more stable and smooth.
[0018] (4) When the limiting plate 44 is engaged with the groove 43, the bearing plate 50 can be closed in the groove 43. The slider 2 46 can be connected to the bearing plate 50. When the bearing plate 50 is transporting goods, the impact force on the goods caused by the sudden stop of the lifting machine can be relieved by the spring 49. Through the slide groove 4 51 and the double threaded rod 52 in the slide groove 4 51 on one side of the bearing plate 50, when the double threaded rod 52 is turned by the knob, because the threads at both ends of the double threaded rod 52 are opposite, it will drive the slider 3 53 connected to both ends of the double threaded rod 52 to slide, thereby moving the support rod 54 and changing the distance between the two bearing plates 50. The increased spacing between the two support plates 50 facilitates connection with the limiting plate 44. This allows for layered support of goods to be transported, enabling the sorting and placement of multiple beer bottles during simultaneous transport, thus preventing the risk of misplacement due to overcrowding. A connecting rod 57 and a connecting block 58 at the other end of the support plate 50 allow the support plate 50 to be positioned and fixed by pulling the connecting block 58 after the spacing between the support plates 50 is expanded, engaging its slot with the limiting rod 47. The connecting rod 57 can slide within the sliding groove 56 to maintain the connection between the connecting block 58 and the support plate 50, facilitating quick connection and installation between the support plate 50 and the limiting plate 44.

[0033] The invention will now be further described with reference to the accompanying drawings and specific embodiments:
[0034] Example 1:
[0035] Please see Figure 1-11According to an embodiment of the present invention, a lifting machine with convenient transportation and good safety performance includes a housing 1, a power unit 2, and a lifting device 3. The upper end of the housing 1 is connected to the power unit 2, and a slide groove 4 is formed on one side of the housing 1. The lifting device 3 is disposed within the slide groove 4. The lifting device 3 includes a housing 5, a buffer mechanism 6, and a protective mechanism 7. Through the housing 5, buffer mechanism 6, and protective mechanism 7, the operation of the power unit 2 raises the housing 5 to transport goods, allowing them to be stored in higher locations or moved down from higher shelves. The protective mechanism 7 protects the housing 5 in case the power unit 2 malfunctions or fails, preventing the housing 5 from falling and being damaged. The buffer mechanism 6 can cushion the goods inside the box 5, preventing damage to the goods due to impact and thus economic losses, making the elevator safer. Both sides of the first slide 4 are provided with second slide 8, and each second slide 8 is equipped with a protective mechanism 7. The protective mechanism 7 includes a slider 9, a screw rod 10, and a limiting ring 11. Slider 9 is slidably arranged in each second slide 8, and a box 5 is fixedly connected between the two sliders 9. The buffer mechanism 6 is provided inside the box 5. A screw rod 10 is provided on one side of the second slide 8 and passes through the slider 9. Both ends of the screw rod 10 are movably connected to the second slide 8 via bearings. The upper end of the screw rod 10 is connected to several locking blocks 12 via a rotating shaft. Each of the locking blocks 12 has a limiting block 13 on its inner side, which is fixedly connected to the spiral rod 10. Each limiting block 13 has a spring groove 14 on the side away from the locking block 12. A connecting piece 15 is slidably disposed in the spring groove 14. A spring 16 is fixedly connected between the connecting piece 15 and the spring groove 14. The connecting piece 15 passes through the limiting block 13 and engages with the locking block 12. A limiting ring 11 is sleeved on the upper end of the spiral rod 10. A groove 17 that mates with the locking block 12 is formed in the limiting ring 11. The limiting ring 11 is fixedly connected to the housing 1. The slider 9 in the sliding groove 8 provides auxiliary guidance for the housing 5 during movement, thus facilitating the movement of the housing 5. The movement is smoother and more stable, making cargo handling safer. The spiral rod 10 allows the slider 9 to rotate as it slides. When the slider 9 slides normally, the rotation of the spiral rod 10 is insufficient to throw out the locking block 12 connected by the shaft, so the locking block 12 does not contact the locking groove 17, and the spiral rod 10 can rotate normally. When the box 5 falls uncontrollably, the slider 9 drives the spiral rod 10 to rotate rapidly. The centrifugal force throws out the locking block 12, which then contacts the locking groove 17 and locks the spiral rod 10, preventing the slider 9 from continuing to slide. This protects the box 5. The impact of the sudden stop is cushioned by the buffer mechanism 6 to prevent damage to the cargo. The spring 16 and the connecting piece 15 are also included.After the housing 5 has been properly inspected and repaired, the locking block 12 can be pulled back to separate it from the slot 17, allowing the screw rod 10 to continue rotating.
[0036] Through the above-described solution of the present invention, the box 5, buffer mechanism 6, and protection mechanism 7 are configured to lift the box 5 via the operation of the power unit 2, thereby transporting goods. This allows goods to be stored in higher locations or moved down from higher shelves. The protection mechanism 7 protects the box 5 in case of power unit 2 failure or malfunction, preventing it from falling and being damaged. The buffer mechanism 6 cushions the goods inside the box 5, preventing damage due to impact and economic losses, thus enhancing the safety of the elevator. The slider 9 within the sliding groove 8 provides auxiliary guidance to the box 5 during movement, making its movement smoother and more stable, and ensuring safer transport of goods. The spiral rod 1... The slider 9 can drive the screw rod 10 to rotate when sliding. When the slider 9 slides normally, the rotation of the screw rod 10 is insufficient to throw out the locking block 12 connected by the rotating shaft, so the locking block 12 does not contact the locking groove 17, and the screw rod 10 can rotate normally. When the box 5 falls uncontrollably, the slider 9 drives the screw rod 10 to rotate rapidly, and the centrifugal force throws out the locking block 12, which then contacts the locking groove 17 and locks the screw rod 10, preventing the slider 9 from continuing to slide, thus protecting the box 5. The impact force of the sudden stop of the box 5 will be buffered by the buffer mechanism 6 to avoid damage to the goods. The spring 16 and the connecting piece 15 can pull back the locking block 12 after the box 5 is repaired and normal, so that the locking block 12 separates from the locking groove 17, and the screw rod 10 can continue to rotate.
[0037] Example 2:
[0038] Please see Figure 3-7According to an embodiment of the present invention, a lifting machine with convenient transportation and good safety performance is provided. A through hole 18 is provided on one side of the slider 9, and a spiral rod 10 is sleeved thereon. A plurality of balls 19 are disposed in the through hole 18 and cooperate with and contact the spiral rod 10. Through the through hole 18 on one side of the slider 9 and the balls 19 in contact with the spiral rod 10 within the through hole 18, when the slider 9 slides, the balls 19 roll in the groove of the spiral rod 10, thereby driving the spiral rod 10 to rotate. When the spiral rod 10 is stuck and cannot rotate, it can limit the slider 9, thereby preventing the box 5 from falling. A sliding rod 20 is fixedly connected to the other side of the sliding groove 8 and passes through the slider 9. The sliding rod 20 can limit and guide the slider 9, making the slider 9 slide more smoothly and stably. The buffer mechanism 6 includes a support platform 21 and a baffle 22. The box... The lower inner wall of box 5 has a groove 23, in which a support platform 21 is slidably fitted. Several spring grooves 24 are formed at the lower end of groove 23, and each spring groove 24 is connected to the support platform 21 via a spring 25. Grooves 26 are formed on both sides of groove 23, and each groove 26 is movably connected to a baffle 22 via a pivot. A spring piece 27 is fixedly connected between the baffle 22 and the groove 26. The support platform 21 can support the goods, and the spring piece 27, which cooperates with the baffle 22 and the groove 26 inside box 5, allows the baffle 22 to support the support platform 21. When box 5 falls and stops suddenly, the elasticity of the baffle 22 and the spring piece 27 cushions the support platform 21, and the springs 25 further enhance the cushioning effect, preventing damage to the goods due to the inertia of a sudden stop.
[0039] Through the above-described solution of the present invention, by using the through hole 18 on one side of the slider 9 and the ball bearing 19 in contact with the screw rod 10 inside the through hole 18, when the slider 9 slides, the ball bearing 19 rolls in the groove of the screw rod 10, thereby driving the screw rod 10 to rotate. When the screw rod 10 is stuck and cannot rotate, the slider 9 can be limited, thereby preventing the box 5 from falling. The sliding rod 20 can limit and guide the slider 9, making the slider 9 slide more smoothly and stably. The support platform 21 can support the goods, and the spring piece 27 between the baffle 22 and the groove 26 inside the box 5 can support the support platform 21. When the box 5 falls and stops suddenly, the elasticity of the baffle 22 and the spring piece 27 buffers the support platform 21, and the spring 25 can further improve the buffering effect of the support platform 21, so that the goods will not be damaged due to the inertia of the sudden stop.
[0040] Example 3:
[0041] Please see Figure 2 , Figure 3 and Figure 8 According to an embodiment of the present invention, a lifting machine with convenient transportation and good safety performance is provided. The power unit 2 includes a motor 28, a connecting frame 29, and a transmission mechanism 30. Two connecting frames 29 are fixedly connected to one side of the upper end of the housing 1. A motor 28 is fixedly connected inside each connecting frame 29. The outer shaft of the motor 28 is connected to the transmission mechanism 30 through a torque protection device 31. By using two motors 28 and two connecting frames 29, the force on the housing 5 is more even when the housing 5 is raised and lowered by the motor 28 driving the transmission mechanism 30, resulting in a better lifting effect and reducing the pressure on the motor 28. The torque protection device 31 can be used to... To prevent the rapid increase in pressure on the other motor 28 due to a failure of one motor 28, thus causing damage, the torque protection device 31 separates the housing 5 from the motor 28 during its descent, preventing simultaneous damage to both motors 28. The device includes a first turntable 32 and a second turntable 33. The outer shafts of all motors 28 are fixedly connected to the first turntable 32. The second turntable 33 is located on one side of the first turntable 32 and contacts it. The first turntable 32 has several circular grooves 34 on the side near the second turntable 33. Each groove 34 contains a movable ball bearing 35. A spring 36 is fixedly connected between each ball bearing 35 and the groove 34. The second turntable 33... The turntable 33 is provided with a ball groove that mates with the second ball 35. The side of the turntable 33 furthest from the first turntable 32 is connected to a transmission mechanism 30 via a rotating shaft. Through the turntable 32 and turntable 33, when the torque between the motor 28 and the transmission mechanism 30 increases, the turntable 33 presses the second ball 35, causing it to slide into the circular groove 34, thus separating the second ball 35 from the turntable 33. This disconnects the connection between the first turntable 32 and the second turntable 33, protecting the motor 28 from overload damage. The transmission mechanism 30 includes a roller 37 and a chain 38. A groove 39 is provided at the upper end of the housing 1. The groove 39 is used for... A rotating shaft connects to a roller 37. The upper end of the groove 39 is connected to a rolling roller 40 via the rotating shaft. A chain 38 is wound around the outer wall of the roller 37 and is fixedly connected to the upper end of the box 5 via the rolling roller 40. One side of the turntable 33 is fixedly connected to a bevel gear 41 via a rotating shaft. One side of the bevel gear 41 is meshed with a bevel gear 42. One side of the bevel gear 42 is fixedly connected to a roller 37 via a rotating shaft. With the roller 37 and rolling roller 40, when the roller 37 rotates, the chain 38 is connected to the box 5 via the rolling roller 40, so that the force on the box 5 remains vertical, thereby making the movement of the box 5 more stable and smooth.
[0042] Through the above-described solution of the present invention, the two motors 28 and two connecting frames 29 enable the motors 28 to drive the transmission mechanism 30, making the force on the housing 5 more even when it is raised and lowered, resulting in a better lifting effect and reducing the pressure borne by the motors 28. The torque protection device 31 prevents the pressure on the other motor 28 from rising sharply and causing damage if one motor 28 fails, thus preventing the housing 5 from separating from the motors 28 during descent and avoiding simultaneous damage to both motors 28. The turntables 32 and 33 further enhance this protection. When the torque between the motor 28 and the transmission mechanism 30 increases, the turntable 2 33 squeezes the ball 2 35, causing the ball 2 35 to slide into the circular groove 34, thereby separating the ball 2 35 from the turntable 2 33. This disconnects the connection between the turntable 1 32 and the turntable 2 33, protecting the motor 28 from overload damage. Through the set roller 37 and rolling roller 40, when the roller 37 rotates, the chain 38 is connected to the box 5 through the rolling roller 40, keeping the force on the box 5 vertical, thus making the movement of the box 5 more stable and smooth.
[0043] Example 4:
[0044] Please see Figure 9-11According to an embodiment of the present invention, a hoist with good safety performance and convenient conveying is provided. The upper inner wall of the housing 5 has a groove 43. A limiting plate 44 is hinged to one side of the lower end of the groove 43, and the other side of the lower end of the groove 43 is engaged with the other end of the limiting plate 44. A plurality of sliding grooves 45 are provided on one side of the limiting plate 44. A slider 46 is slidably fitted within each sliding groove 45. A limiting rod 47 is fixedly connected to one side of each slider 46. Sliding rods 48 are fixedly connected to each sliding groove 45 and pass through each slider 46. A spring 49 is fixedly connected between one side of each slider 46 and the sliding groove 45. A plurality of bearing plates 50 are movably arranged within the groove 43, and the limiting plates are used to control the movement of the bearing plates. When the limiting plate 44 engages with the groove 43, the bearing plate 50 can be closed within the groove 43. The slider 46 can be connected to the bearing plate 50. When the bearing plate 50 is transporting goods, the impact force on the goods caused by the sudden stop of the lifting machine can be relieved by the spring 49. Both sides of the bearing plate 50 are provided with sliding grooves 51. A double threaded rod 52 is slidably arranged in the sliding groove 51. One end of the double threaded rod 52 is movably connected to the sliding groove 51 through a bearing. The other end of the double threaded rod 52 passes through the bearing plate 50 and is fixedly connected to a knob. Two sliders 53 are threadedly connected to the outer wall of the double threaded rod 52. One end of each slider 53 is open to the sliding groove 51. A support rod 54 is movably connected via a pivot. The end of the support rod 54 away from the slider 53 is movably connected to another bearing plate 50 via a pivot. A connecting chain 55 is fixedly connected between the uppermost bearing plate 50 and the groove 43. A double-threaded rod 52 is provided on one side of the bearing plate 50 via a sliding groove 51. When the double-threaded rod 52 is rotated by a knob, because the threads at both ends of the double-threaded rod 52 are opposite, it causes the slider 53 connected to both ends of the double-threaded rod 52 to slide, thereby moving the support rod 54 and changing the distance between the two bearing plates 50 to facilitate connection with the limiting plate 44. The increased distance between the two bearing plates 50 allows for layered support of the goods to be transported. The support plate 50 is designed to facilitate the sorting and arrangement of multiple beer bottles during simultaneous transport, preventing them from piling up and increasing the risk of misplacement. Each of the other ends of the support plate 50 has a sliding groove 56, within which a connecting rod 57 is slidably mounted. A connecting block 58 is fixedly connected to the end of each connecting rod 57 away from the sliding groove 56. One side of the connecting block 58 has a slot that engages with the limiting rod 47. By using the connecting rod 57 and connecting block 58 at the other end of the support plate 50, when the spacing between the support plates 50 is expanded, pulling the connecting block 58 causes its slot to engage with the limiting rod 47, thus limiting and fixing the position of the support plate 50. The connecting rod 57 can then slide within the sliding groove 56.This is to ensure the connection between the connecting block 58 and the support plate 50, and to facilitate quick connection and installation between the support plate 50 and the limiting plate 44.
[0045] Through the above-described solution of the present invention, when the limiting plate 44 is engaged with the groove 43, the bearing plate 50 can be closed within the groove 43. The slider 46 can be connected to the bearing plate 50. When the bearing plate 50 is transporting goods, the impact force on the goods caused by the sudden stop of the lifting machine can be relieved by the spring 49. Through the slide groove 51 and the double threaded rod 52 in the slide groove 51 on one side of the bearing plate 50, when the double threaded rod 52 is rotated by the knob, because the threads at both ends of the double threaded rod 52 are opposite, it will drive the slider 53 connected to both ends of the double threaded rod 52 to slide, thereby moving the support rod 54 and changing the position of the two bearing plates 50. The spacing between the two support plates 50 is designed to facilitate connection with the limiting plate 44. The increased spacing between the two support plates 50 allows for layered support of the goods to be transported, enabling the classification and placement of multiple beer bottles during simultaneous transport, thus avoiding the risk of misplacement due to stacking. With the connecting rod 57 and connecting block 58 located at the other end of the support plate 50, when the spacing between the support plates 50 is expanded, the connecting block 58 can be pulled to engage with the limiting rod 47, thereby fixing the position of the support plate 50. The connecting rod 57 can slide within the slide groove 56 to maintain the connection between the connecting block 58 and the support plate 50, facilitating quick connection and installation between the support plate 50 and the limiting plate 44.
[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
