Description

Technical Field

[0001] The utility model relates to the technical field of storage devices, in particular to a vertical lifting cabinet conveying platform. Background Art

[0002] Vertical lift cabinets are automated storage equipment that use pallets as storage units. Container lift platforms are a type of lifting machinery used to transport goods vertically. They are widely used in the field of warehousing equipment. Through the lifting and lowering motion of the platform's transverse mechanism, pallets containing goods are brought to the operator or delivered to the appropriate location within the cabinet. During delivery, an automatic height measurement device at the entrance detects the height of the stored items, allowing them to be quickly stored in the optimal location within the warehouse. Retrieving and delivering items requires no manual handling, allowing for high-speed stocking and truly automated storage and retrieval.

[0003] Currently, when storing goods, a transmission system failure may cause the lifting platform to fall rapidly, causing damage to the goods. This situation not only causes direct economic losses to the goods themselves, but may also trigger a series of chain reactions, with a negative impact on the entire logistics and supply chain. When the lifting platform falls rapidly due to a transmission system failure, the goods on the platform will be subjected to severe impact and vibration. This impact force may cause the packaging of the goods to be damaged, deformed or scattered, thereby affecting the integrity and availability of the goods. Especially for high-value goods such as fragile items and precision instruments, once damaged, the repair cost is often high, or even may not be able to be repaired, resulting in the scrapping of the goods. Utility Model Content

[0004] The purpose of the utility model is to provide a vertical lifting cabinet conveying platform to solve the problem raised in the above background technology that when storing goods, the transmission system fails, causing the lifting platform to fall rapidly and causing damage to the goods.

The buffer mechanism includes a fixed block, which is fixedly installed between the upper guide rail and the lower guide rail and forms an integral part with the upper guide rail and the lower guide rail. A first spring and an airbag are fixedly installed inside the fixed block;

[0017] The utility model is provided with a buffer mechanism and a control mechanism. In the initial state, the electromagnetic block is in the open state, and the first spring and the second spring are in the compressed state. When the lifting platform fails and falls rapidly, the lower guide wheel first passes through the surface of the speed sensor. The speed sensor detects that the descending speed of the lower guide wheel exceeds the preset value and responds in time. The electromagnetic block is controlled by the controller to cut off the power supply, the electromagnetic block loses its magnetic force, and the magnetic block quickly separates from the electromagnetic block. Under the rebound action of the second spring, the entire buffer mechanism moves outward from between the upper guide rail and the lower guide rail. At the same time, under the action of the second spring, the abutment block rises. At this time, the upper guide rail contacts the abutment block, which prevents the lifting platform from continuing to fall. Through the setting of the first spring and the airbag, the lifting platform is limited and a buffering effect is played at the same time, thereby avoiding the rapid fall of the lifting platform, causing damage to the goods, reducing the impact and vibration of the goods on the lifting platform by external forces, and ensuring the integrity and availability of the goods.

[0026] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0028] like Figure 1-6 As shown, the present application provides a vertical lifting cabinet conveying platform, including a cabinet body 1:

[0029] Positioning columns 2, which are fixedly installed around the interior of the cabinet 1, and upper guide rails 3 and lower guide rails 31 are fixedly installed on the surfaces of the four groups of positioning columns 2;

[0030] A lifting platform 6 is slidably connected to the interior of the cabinet 1;

[0031] Specifically, such as Figure 3 As shown, upper guide wheels 61 are fixedly installed around the upper surface of the lifting platform 6, and lower guide wheels 62 are fixedly installed around the lower surface of the lifting platform 6. The upper guide wheels 61 and the lower guide wheels 62 are both slidably connected to the surfaces of the upper guide rail 3 and the lower guide rail 31;

[0032] In this embodiment, the lifting platform 6 can move up and down inside the cabinet 1 by sliding in cooperation between the upper guide wheel 61 , the lower guide wheel 62 and the upper guide rail 3 , the lower guide rail 31 .

[0033] The buffer mechanism 4 is located between the upper guide rail 3 and the lower guide rail 31 and forms an integral part with the upper guide rail 3 and the lower guide rail 31. The buffer mechanism 4 plays a buffering role when the lifting platform 6 falls rapidly. The buffer mechanism 4 includes a fixed block 41. The fixed block 41 is fixedly installed between the upper guide rail 3 and the lower guide rail 31 and forms an integral part with the upper guide rail 3 and the lower guide rail 31. A first spring 45 and an airbag 48 are fixedly installed inside the fixed block 41;

[0034] Specifically, such as Figure 5 As shown, a first connecting rod 42 is slidably connected to the interior of the fixed block 41, an abutting block 43 is fixedly mounted on one end of the first connecting rod 42, and the upper surface of the abutting block 43 is movably fitted with the lower surface of the upper guide rail 3, and a slider 47 is fixedly mounted on the other end of the first connecting rod 42, and the lower surface of the slider 47 is movably fitted with the surface of the airbag 48;

[0035] In this embodiment: the abutment block 43 can pop out under the action of the first spring 45 and contact the bottom of the upper guide wheel 61 to limit the upper guide wheel 61. The first connecting rod 42 can move up and down. Through the cooperation of the first spring 45 and the airbag 48, the buffering work of the lifting platform 6 is achieved.

[0036] Specifically, such as Figure 5 As shown, a first spring slot 44 is defined inside the fixed block 41, one end of a first spring 45 is fixedly connected to the inside of the first spring slot 44, and the other end of the first spring 45 is fixedly connected to the lower surface of the abutment block 43. A slide slot 46 is defined inside the fixed block 41 below the first spring slot 44, a slider 47 is slidably connected to the inside of the slide slot 46, an airbag 48 is fixedly mounted at the bottom of the slide slot 46, a first connecting rod 42 is slidably connected to the first spring slot 44 and the inside of the slide slot 46, and the first connecting rod 42 passes through the inside of the first spring 45;

[0037] In this embodiment, the first spring 45 pushes the abutment block 43 out, and at the same time the first connecting rod 42 moves upward, and the slider 47 at the end of the first connecting rod 42 moves upward inside the sliding groove 46 to prevent the abutment block 43 from detaching from the top of the fixed block 41.

[0038] The control mechanism 5 is located inside the positioning column 2. The control mechanism 5 controls the buffer mechanism 4 so that the buffer mechanism 4 can be pushed out from the middle position between the upper guide rail 3 and the lower guide rail 31. The control mechanism 5 includes a controller 51 and a speed sensor 52. The controller 51 is fixedly mounted inside the positioning column 2, and the speed sensor 52 is fixedly mounted on the surface of the upper guide rail 3.

[0039] Specifically, such as Figure 5 As shown, a placement groove 54 is provided inside the positioning column 2, an electromagnetic block 53 is fixedly installed inside the placement groove 54, and a magnetic block 55 is slidably connected inside the placement groove 54. One side of the electromagnetic block 53 is movably fitted with one side of the magnetic block 55. The output end of the controller 51 is electrically connected to the speed sensor 52 and the input end of the electromagnetic block 53.

[0040] In this embodiment, in the initial state, the electromagnetic block 53 is in the on state, the electromagnetic block 53 and the magnetic block 55 are adsorbed together, and the second connecting rod 56 pulls the buffer mechanism 4 back to the middle of the upper guide rail 3 and the lower guide rail 31 .

[0041] Specifically, such as Figure 5 As shown, a second connecting rod 56 is fixedly installed on the other side of the magnetic block 55, and the end of the second connecting rod 56 is fixedly connected to the surface of the fixed block 41. A second spring groove 57 is opened on one side of the placement groove 54, and a second spring 58 is fixedly installed inside the second spring groove 57. The other end of the second spring 58 is fixedly connected to the surface of the fixed block 41, and the second connecting rod 56 runs through the interior of the second spring 58.

[0042] In this embodiment: the second spring 58 is in a compressed state. When the electromagnetic block 53 is closed, the magnetic block 55 detaches from the surface of the electromagnetic block 53, and the second spring 58 drives the fixed block 41 to pop out as a whole, so that the buffer mechanism 4 can intercept the lifting platform 6.

[0043] The specific scheme is as follows: in the initial state, the electromagnetic block 53 is in the open state, and the first spring 45 and the second spring 58 are in the compressed state. When the lifting platform 6 fails and falls rapidly, the lower guide wheel 62 first passes the surface of the speed sensor 52. The speed sensor 52 detects that the descending speed of the lower guide wheel 62 exceeds the preset value and sends a signal to the controller 51. The controller 51 controls the electromagnetic block 53 to cut off the power supply, the electromagnetic block 53 loses the magnetic force, and the magnetic block 55 quickly separates from the electromagnetic block 53. Under the rebound action of the second spring 58, the magnetic block 55 moves to the right inside the placement groove 54, and the entire buffer mechanism 4 moves outward from the middle of the upper guide rail 3 and the lower guide rail 31. At the same time, under the action of the second spring 58, the abutment block 43 rises rapidly. At this time, the upper guide wheel 61 contacts the surface of the abutment block 43, which prevents the lifting platform 6 from continuing to fall. Through the setting of the first spring 45 and the airbag 48, the lifting platform 6 is limited and a buffering effect is played at the same time.
