Description

Technical Field

[0001] The present application relates to a lifting vehicle device, and more particularly to an RTP barrel mobile lifting vehicle device. Background Art

[0002] In the field of pharmaceutical equipment technology, the rapid transfer port (RTP) valve, as an interface for docking isolators with mobile containers, is widely used in the feeding or discharging of articles such as appliance accessories and materials. However, in actual applications, there have always been many problems when the RTP barrel or transfer bag is docked with the sterile transfer RTP door.

[0003] Previously, this kind of docking mainly relied on manual methods. When the RTP barrel or transfer bag is full of materials, the docking work not only has to overcome its own weight but also has to deal with the height of the sterile transfer RTP door. For example, manual workers need to work at heights, which brings great safety risks and also greatly consumes the physical strength of the operators and increases their fatigue.

[0004] When the isolator and the sterile transfer RTP door are used in combination, there are obvious defects in the traditional docking (layout) of the RTP barrel and the RTP door. First, manually carrying the RTP barrel full of materials, due to its large weight and size, causes huge physical consumption of the operators and is prone to safety accidents. Second, when the isolator equipment is equipped with multiple sterile transfer RTP doors and the docking heights are too high and inconsistent, personnel need to use auxiliary tools such as ladders for operation, which further increases the risk factor. Moreover, this also requires additional auxiliary personnel, which not only increases the labor cost of the enterprise but also increases the difficulty of cleaning and maintenance when using such auxiliary tools in the clean area, and is not conducive to the effective control of the clean area.

[0005] Facing these problems, if the equipment users and their enterprises want to solve them, in the case of extremely fatigued operators and high safety risks, they not only need to add auxiliary operators to increase labor costs but also need to bear the risk of possible safety accidents. However, currently, the traditional manual operation method still cannot effectively solve the above problems. Utility Model Content

[0006] The purpose of the present application is to provide an RTP barrel mobile lifting vehicle device for the above problems existing in the prior art.

[0007] To achieve the above application purpose, the present application adopts the following technical solutions: An RTP barrel mobile lifting vehicle device includes:

[0008] A chassis, with casters installed at the bottom and the vertical column at the top being movably connected to the gearbox assembly;

[0009] Gearbox assembly, including a gearbox, a lead screw disposed within the gearbox, and a gear transmission structure drivingly connected to the lead screw, which is drivingly connected to a handle through the gear transmission structure;

[0010] Barrel support plate assembly, disposed on top of the gearbox assembly for placing RTP barrels;

[0011] Lead screw nut, mating with the lead screw and installed on top of the column;

[0012] Handle, which rotates to move the gearbox assembly up and down on the chassis.

[0013] Further, the gear transmission structure includes a driving bevel gear rotatably connected coaxially with the handle, a driven bevel gear meshing with the driving bevel gear, and the driven bevel gear is rotatably connected coaxially with the top of the lead screw.

[0014] Further, a limit sleeve and a limit nut are provided at the bottom of the lead screw to limit the lead screw nut through the limit sleeve and the limit nut.

[0015] Further, the gearbox assembly further includes an upper limit plate and a lower limit plate disposed on the inner wall of the gearbox to guide the gearbox through the upper limit plate and the lower limit plate.

[0016] Further, a copper sleeve is provided between the lead screw and the gearbox.

[0017] Further, a bearing is provided between the handle and the gearbox.

[0018] Further, the casters are universal brake casters.

[0019] Further, the barrel support plate assembly includes a barrel support plate disposed on top of the gearbox, barrel limit blocks and rollers disposed on the barrel support plate, inclined braces are provided on both sides in the width direction of the barrel support plate, the rollers are installed on the inclined braces, and the barrel limit blocks are used to laterally position the RTP barrel.

[0020] Further, a handle is also provided on the barrel support plate.

[0021] Further, two rollers are provided on each inclined brace.

[0022] Compared with the prior art, the present utility model has the following beneficial effects:

[0023] 1. Significantly reduce the physical consumption and fatigue of the operator: Through the liftable design, the operator no longer needs to laboriously carry heavy fully loaded RTP barrels for docking, avoiding excessive physical consumption caused by manual handling. For example, in the past, manually carrying fully loaded RTP barrels might require a lot of effort and even cause muscle strains, while with the use of this device, the operator can easily adjust the RTP barrel to the appropriate height.

[0024] 2. Reduce safety risks: It avoids dangerous situations such as falling caused by manual climbing operations and ensures the life safety of operators. For example, in traditional operations, climbing operations may cause falls due to loss of balance or unstable tools, but this device eliminates this hidden danger.

[0025] 3. Improve docking efficiency and accuracy: The RTP barrel can be accurately adjusted to the height and position that matches the aseptic transfer RTP door, making docking faster, simpler and more accurate, which helps the subsequent production to proceed smoothly, quickly and orderly. If there is no such device, docking may require multiple attempts and adjustments, which wastes time and may affect the production schedule, but with this device, it can be done in one go.

[0026] 4. Reduce enterprise costs: No additional auxiliary personnel are needed, which reduces labor costs. At the same time, it reduces potential losses and compensation costs caused by safety accidents. For example, an enterprise originally needed to hire multiple auxiliary personnel to assist in handling and docking, but now using this device can save this part of labor expenses.

[0027] 5. Easy to manage the clean area: No auxiliary tools such as ladders are needed, which reduces the difficulty of cleaning and maintaining the clean area, and is conducive to maintaining a good environment in the clean area. For example, the use of tools such as ladders may bring dust and debris, increasing the workload and difficulty of cleaning, but the use of this device avoids this problem.

[0028] 6.Flexibility and versatility: Universal brake casters allow the device to be flexibly moved and fixed, suitable for different work scenes and locations. The design of the barrel tray assembly can adapt to RTP barrels of different sizes, improving the versatility of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The gearbox assembly 3 includes a gearbox 31, a screw rod 35 provided in the gearbox 31, and a gear transmission structure drivingly connected to the screw rod 35, and is drivingly connected to the handle 6 through the gear transmission structure;

[0040] In this embodiment, the gear transmission structure includes a driving bevel gear 312 rotatably connected coaxially with the handle 6, a driven bevel gear 310 meshing with the driving bevel gear 312, and the driven bevel gear 310 is rotatably connected coaxially with the top of the lead screw 35. A limit sleeve 33 and a limit nut 34 are provided at the bottom of the lead screw 35 to limit the lead screw nut 7 through the limit sleeve 33 and the limit nut 34. A bronze bushing 39 is provided between the lead screw 35 and the gearbox 31, and an intermediate sleeve 38 and a lower sleeve 37 are also provided below the bronze bushing 39.

[0041] Preferably, the gearbox assembly 3 further includes an upper limit plate 32 and a lower limit plate 36 provided on the inner wall of the gearbox 31 to guide the gearbox 31 through the upper limit plate 32 and the lower limit plate 36.

[0042] Specifically, the lead screw 35 is connected to the lead screw nut 7, and the bottom of the lead screw 35 is limited by the limit sleeve 33 and the limit nut 34. The lower sleeve 37, the intermediate sleeve 38, and the bronze bushing 39 are connected to the upper part of the lead screw 35 and the gearbox 31. The driven bevel gear 310 is connected to the lead screw 35 through a locking nut 311. The upper limit plate 32 and the lower limit plate 36 are fixed to the inner side of the gearbox 31, and the bevel gear rotating shaft 316 is connected to the gearbox 31 through a bearing 313.

[0043] The bucket support plate assembly 4 is provided on the top of the gearbox assembly 3 for placing the RTP bucket 5;

[0044] In this embodiment, the bucket support plate assembly 4 includes a bucket support plate 41 provided on the top of the gearbox 3, a bucket limit block 42, rollers 44, and a handle 43 provided on the bucket support plate 41. Tilted braces are provided on both sides in the width direction of the bucket support plate 41, and the rollers 44 are installed on the braces. The bucket limit block 42 is used to laterally position the RTP bucket 5. The handle 43 is connected to the bucket support plate 41, the bucket limit block 42 is connected to the bucket support plate 41, and the rollers 44 are connected to the bucket support plate 41 through roller spindles 45.

[0045] Preferably, two rollers 44 are provided on each brace.

[0046] The lead screw nut 7 is matched with the lead screw 35 and installed at the top of the column;

[0047] The handle 6 is used to move the gearbox assembly 3 up and down on the chassis 1 by rotation. A bearing 313 is provided between the handle 6 and the gearbox 31. The bearing end cover 314 fixes the bevel gear rotating shaft 316. A rotating shaft spacer 315 is connected between the bearing end cover 314 and the bevel gear rotating shaft 316. The driving bevel gear 312 is connected to the bevel gear rotating shaft 316, and the handle 6 is connected to the bevel gear rotating shaft 316.

[0048] Implementation form: Pull the RTP bucket 5 to move its position by the handle 43. Rotate the handle 43 to drive the driving bevel gear 312 to rotate. The driving bevel gear 312 is connected to drive the driven bevel gear 310 to rotate, and the lead screw 35 rotates accordingly. Move up and down on the lead screw nut 7 (since the lead screw nut 7 is fixed and cannot rotate, so only the lead screw 35 can rotate and move up and down at the same time). The gearbox 31 component and the bucket support plate 41 component then move up and down. The upper limit plate 32 and the lower limit plate 36 play a role in positioning the gearbox 31 up and down with the chassis 1. The lower sleeve 37, the middle sleeve 38, and the copper sleeve 39 play a role in sliding friction between the gearbox 31 and the lead screw 35. The limit sleeve 33 plays a role in limiting the lower end of the lead screw 35. The bearing 313 plays a rolling role for the bevel gear rotating shaft 316. The bucket limit block 42 plays a role in laterally positioning the RTP bucket 5.

[0049] Embodiment 2

[0050] First, when using the RTP bucket mobile lifting vehicle device of the present utility model, the operator moves it to the position where the fully loaded RTP bucket is located by pushing the device and using the universal brake casters 2 at the bottom. Since the casters 2 are universal brake casters 2, they can flexibly change the moving direction and are fixed by braking after reaching the designated position to ensure the stability of the device.

[0051] Next, place the RTP bucket on the bucket support plate assembly 4. The width and shape of the bucket support plate 41 are carefully designed to adapt to common specifications of RTP buckets. The bucket limit block 42 on the bucket support plate 41 can laterally position the RTP bucket to prevent it from undergoing lateral displacement during lifting and moving. At the same time, the rollers 44 on the diagonal brace and the handle 43 on the bucket support plate 41 provide convenience for the operator to place and adjust the position of the RTP bucket.

[0052] When adjusting the height of the RTP bucket, the operator holds the handle 6 and rotates it. The rotation of the handle 6 drives the driven bevel gear 310 to rotate through the driving bevel gear 312 that is coaxially rotatably connected thereto. The driven bevel gear 310 is coaxially rotatably connected to the top of the lead screw 35, thereby driving the lead screw 35 to rotate. The lead screw 35 cooperates with the lead screw nut 7 installed at the top of the column to realize the up and down movement of the gearbox assembly 3.

[0053] To ensure the stable operation of the lead screw 35, a copper sleeve 39 is provided between the lead screw 35 and the gearbox 31 to reduce friction and wear. At the same time, the upper limit plate 32 and the lower limit plate 36 on the inner wall of the gearbox 31 play a guiding role in the movement of the gearbox 31 to ensure its vertical lifting without deviation or shaking.

[0054] At the bottom of the lead screw 35, the limit sleeve 33 and the limit nut 34 are provided to effectively limit the movement range of the lead screw nut 7, avoiding equipment damage or operation errors caused by excessive lifting.

[0055] After the RTP barrel is lifted to a height matching the aseptic transfer RTP door, the operator pushes the device again to accurately dock the RTP barrel to the aseptic transfer RTP door.

[0056] For example, in the actual production of a pharmaceutical factory, an RTP barrel filled with drug raw materials needs to be docked with an aseptic transfer RTP door at a higher position. The operator first moves this device to the side of the RTP barrel, places the barrel on the barrel support plate 41 and fixes it. Then rotate the handle 6 to smoothly lift the RTP barrel to the same height as the aseptic transfer RTP door. Finally, easily push the device to complete the docking. The whole process is fast, accurate and safe, greatly improving the production efficiency.

[0058] It can be understood that the term "a" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of this element can be multiple. The term "a" cannot be understood as a limitation on the quantity.

[0059] Although terms such as chassis 1, casters 2, gearbox assembly 3, barrel support plate assembly 4, RTP barrel 5, handle 6, lead screw nut 7, gearbox 31, upper limit plate 32, limit sleeve 33, limit nut 34, lead screw 35, lower limit plate 36, lower sleeve 37, intermediate sleeve 38, copper sleeve 39, driven bevel gear 310, locking nut 311, driving bevel gear 312, bearing 313, bearing end cover 314, shaft pad 315, bevel gear shaft 316, barrel support plate 41, barrel limit block 42, handle 43, roller 44, mandrel 45 are used more in this text, the possibility of using other terms is not excluded.
