Description

Technical Field

[0001] This utility model belongs to the field of transportation and storage equipment technology, specifically a vacuum tube placement vehicle. Background Technology

[0002] In the production, storage, transportation, and daily use of vacuum tubes, safe storage and efficient transportation are crucial for ensuring production efficiency and reducing losses. Currently, the industry relies heavily on traditional fixed-structure storage equipment for the storage and transportation of vacuum tubes. This type of equipment has significant compatibility limitations and cannot meet diverse usage needs.

[0003] On the one hand, most existing storage devices are integrated fixed structures that can only provide a single storage space. If the device is designed as a single-layer structure, when a large number of vacuum tubes need to be stored, multiple additional devices will be required due to insufficient space, which not only increases the cost of equipment investment but also occupies more workshop or warehouse space. If the device is designed as a multi-layer fixed structure, when only a small number of vacuum tubes need to be stored, the extra layer space will be idle, resulting in a waste of space resources. In addition, the overall size of multi-layer fixed structure devices is large, which makes them less flexible in narrow workstations or short-distance transportation scenarios and difficult to adjust to adapt to different usage environments.

[0004] Therefore, there is an urgent need for a vacuum tube storage device with a flexible adjustable structure to solve the above-mentioned pain points. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a vacuum tube placement vehicle.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A vacuum tube placement vehicle includes a vehicle body, on the upper part of which a placement frame assembly is detachably mounted. The placement frame assembly has a two-layer structure, including a first placement frame and a second placement frame. The four corners of the upper part of the first placement frame are provided with first slots, and the four corners of the lower part of the second placement frame are provided with second slots. The first placement frame and the second placement frame are detachably connected by four connecting posts and four plug-in components.

[0008] Furthermore, the two ends of the connecting post are respectively inserted into the first slot and the second slot, and the upper and lower ends of the connecting post are provided with insertion holes. The first placement frame is provided with a through hole at each of the first slots, and the second placement frame is provided with a through hole at each of the second slots. The plug-in assembly is respectively installed at the through holes of the first placement frame and the second placement frame.

[0009] Furthermore, after the two ends of the connecting post are respectively inserted into the first slot and the second slot, the insertion holes on the connecting post are aligned with the through holes on the side of the first placement frame and the through holes on the side of the second placement frame.

[0010] Furthermore, the plug-in assembly includes a connecting plate, a connecting spring, and a pin. The connecting plate is fixedly connected to the side wall of the first placement frame or the second placement frame via the connecting spring, and the pin is fixedly installed on the side end of the connecting plate.

[0011] Furthermore, four first threaded holes are provided at the lower end of the vehicle body, and connecting blocks are fixedly installed at the four corners of the lower end of the first placement frame, and a second threaded hole is provided at the upper end of each connecting block.

[0012] Furthermore, the position of the first threaded hole corresponds to the position of the second threaded hole, and the first placement frame and the vehicle body are detachably connected by a long screw passing through the second threaded hole and the first threaded hole.

[0013] Furthermore, a layer of silicone cushioning pad is attached to the bottom of both the first and second placement frames, and the surface of the silicone cushioning pad is provided with anti-slip texture.

[0014] Furthermore, four self-locking casters are fixedly installed at the lower end of the vehicle body, and a push-pull rod is fixedly installed at the upper end of the vehicle body.

[0015] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0016] Fixed connection: refers to a connection in which parts or components are fixed in place and there is no relative movement. It is divided into two types: detachable connection and non-detachable connection.

[0017] (1) Detachable connection: The components are fixed together using screws, splines, wedges, etc. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of the bolts, keys, wedges) and properly tightened.

[0018] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxyacetylene cutting for repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.

[0019] The beneficial effects of this utility model are:

[0020] 1. The first placement frame and the vehicle body, as well as the first placement frame and the second placement frame, are detachably connected, allowing for flexible switching of modes based on the actual storage quantity of vacuum tubes and the usage scenario. When the storage quantity is small or only a small number of vacuum tubes need to be transported over short distances, a single-layer mode of "vehicle body + first placement frame" can be adopted to reduce the overall space occupied by the equipment. When the storage quantity increases or different specifications of vacuum tubes need to be stored separately, a double-layer mode of "vehicle body + first placement frame + second placement frame" can be assembled through connecting columns and plug-in components to improve the utilization rate of storage space and completely solve the problem of "occupying too little space and not having enough space when storing too much" in traditional fixed structure equipment.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] A vacuum tube placement cart, such as Figures 1 to 7 As shown, the system includes a vehicle body 1, with a first placement frame 2 detachably mounted on the upper part of the vehicle body 1, and a second placement frame 3 detachably mounted on the upper part of the first placement frame 2. A first slot 4 is provided at each of the four corners of the upper part of the first placement frame 2, and a second slot 5 is provided at each of the four corners of the lower part of the second placement frame 3. There are four connecting posts 6, with their ends inserted into the first slot 4 and the second slot 5 respectively. Each connecting post 6 has insertion holes 7 at both its upper and lower ends. The first placement frame 2 has through holes 8 at each of the first slot 4, and the second placement frame 3 has through holes 8 at each of the second slot 5. The first placement frame 2 and the connecting posts 6, and the second placement frame 3 and the connecting posts 6, are detachably connected via plug-in components 9. The first placement frame 2 and the vehicle body 1, as well as the first placement frame 2 and the second placement frame 3, are detachably connected. Depending on the number of vacuum tubes to be stored and the usage scenario, a single-layer mode of "vehicle body 1 + first placement frame 2" or a double-layer mode of "vehicle body 1 + first placement frame 2 + second placement frame 3" can be flexibly selected, avoiding space waste or insufficient storage problems caused by fixed structures. When it is necessary to move the placement vehicle (such as for inter-workshop transport or warehouse handling) or to maintain a specific component (such as replacing the placement frame or repairing the connecting column 6), the equipment can be disassembled into independent components such as vehicle body 1, first placement frame 2, second placement frame 3, and connecting column 6 by disassembling the connecting structure. This reduces the difficulty of handling, facilitates targeted maintenance, and reduces the time cost of overall equipment downtime for maintenance. The connecting post 6 is connected to the placement frame via a "slot (first slot 4 / second slot 5) + plug-in component 9". First, the connecting post 6 is initially positioned using the slot to ensure alignment with the placement frame. Then, the plug-in component 9 (with pin 12 passing through the through hole 8 and engaging with the insertion hole 7 of the connecting post 6) provides secondary fixation, preventing the connecting post 6 from shifting or the placement frame from shaking during transportation or use, and avoiding the vacuum tube falling or colliding due to structural loosening. The through holes 8 of the first placement frame 2 and the second placement frame 3 precisely correspond to the insertion holes 7 of the connecting post 6, allowing the plug-in component 9 to be precisely inserted for fixation. This ensures that the overall structure is flat and stable after connection, preventing the placement frame from tilting due to connection deviations, further guaranteeing the stability of the vacuum tube during storage.

[0032] As a preferred embodiment of this utility model, when the two ends of the connecting post 6 are respectively located in the first slot 4 and the second slot 5, the insertion hole 7 on the connecting post 6 is aligned with the through hole 8 on the side of the first placement frame 2 and the through hole 8 on the side of the second placement frame 3; ensuring that the plug-in component 9 can be accurately inserted into the insertion hole 7 to achieve a stable connection.

[0033] In a preferred embodiment of this invention, multiple insertion components 9 are respectively installed at the through holes 8 of the first placement frame 2 and the second placement frame 3. Each insertion component 9 includes a connecting plate 10, a connecting spring 11, and a pin 12. The connecting plate 10 is fixedly connected to the side wall of the first placement frame 2 or the second placement frame 3 via the connecting spring 11, and the pin 12 is fixedly installed on the side end of the connecting plate 10. This structural design makes the insertion and removal of the pin 12 convenient, and under the action of the connecting spring 11, the pin 12 can always maintain a tight fit with the insertion hole 7, preventing the connection from becoming loose.

[0034] In a preferred embodiment of this utility model, the lower end of the vehicle body 1 is provided with four first threaded holes 13, and a connecting block 20 is fixedly installed at each of the four corners of the lower end of the first placement frame 2. Each connecting block 20 is provided with a second threaded hole 14 at its upper end. The connection block 20 increases the contact area between the first placement frame 2 and the vehicle body 1, thereby improving the connection stability.

[0035] In a preferred embodiment of this utility model, the position of the first threaded hole 13 corresponds to the position of the second threaded hole 14, and the first placement frame 2 and the vehicle body 1 are detachably connected by a long screw 15 passing through the second threaded hole 14 and the first threaded hole 13. The threaded connection features reliable connection and convenient disassembly, facilitating the assembly and disassembly of the equipment according to actual needs.

[0036] In a preferred embodiment of this invention, a silicone cushioning pad 16 is adhered to the bottom of both the first placement frame 2 and the second placement frame 3. The surface of the silicone cushioning pad 16 is provided with anti-slip texture 17. The silicone cushioning pad 16 can effectively reduce the impact of external vibrations on the vacuum tube, while the anti-slip texture 17 prevents the vacuum tube from sliding within the placement frame. This double protection ensures the safe storage of the vacuum tube.

[0037] In a preferred embodiment of this utility model, four self-locking casters 18 are fixedly installed at the lower end of the vehicle body 1, and a push-pull rod 19 is fixedly installed at the upper end of the vehicle body 1. The self-locking casters 18 allow the vehicle to steer and move flexibly, while the push-pull rod 19 facilitates pushing by the operator, improving the equipment's transfer efficiency and ease of use.

[0038] Working principle and usage process of this utility model:

[0039] When assembling the vacuum tube placement vehicle, first align the connecting block 20 at the lower end of the first placement frame 2 with the corresponding position at the upper end of the vehicle body 1, so that the second threaded hole 14 on the connecting block 20 is aligned with the first threaded hole 13 on the vehicle body 1. Then, use a long screw 15 to pass through the second threaded hole 14 and the first threaded hole 13 to fix the first placement frame 2 to the vehicle body 1. Next, pull the connecting plate 10 of the insertion assembly 9 on the first placement frame 2 to stretch the connecting spring 11, and the pin 12 will disengage from the through hole 8. Insert the lower ends of the four connecting posts 6 into the four first slots 4 at the upper end of the first placement frame 2 respectively. Release the connecting plate 10, the connecting spring 11 will return to its original position, and the pin 12 will pass through the through hole 8 and be inserted into the insertion hole 7 at the lower end of the connecting post 6, thus completing the fixation of the connecting post 6 to the first placement frame 2. Then, pull the connecting plate 10 of the plug-in component 9 on the second placement frame 3 in the same way, align the four second slots 5 at the lower end of the second placement frame 3 with the upper end of the connecting post 6 and put them in, loosen the connecting plate 10, so that the pin 12 is inserted into the plug hole 7 at the upper end of the connecting post 6, thereby fixing the second placement frame 3 to the connecting post 6, thus completing the assembly of the entire placement vehicle.

[0040] During use, vacuum tubes are placed into the first placement frame 2 and the second placement frame 3 respectively. The silicone cushioning pad 16 at the bottom of the placement frame provides cushioning protection for the vacuum tubes, and the anti-slip texture 17 prevents the vacuum tubes from sliding. The operator holds the push-pull rod 19 and pushes the cart 1. With the help of the self-locking casters 18, the placement cart can be moved to the desired position. After reaching the destination, the self-locking casters 18 are locked to prevent the placement cart from sliding. When it is necessary to disassemble the equipment, the operation is carried out in the reverse order of assembly: first disassemble the second placement frame 3, then disassemble the connecting column 6, and finally disassemble the first placement frame 2. The operation is simple and facilitates the maintenance, transportation, and storage of the equipment.
