Description

Technical Field

[0001] The utility model belongs to the technical field of oxygen cylinder transportation and relates to a transportation vehicle, in particular to a double-layer oxygen cylinder transportation vehicle. Background Art

[0002] There are many types of oxygen cylinder transport vehicles currently used in hospitals, which can be roughly divided into single-cylinder body and double-cylinder body according to the transportation loading capacity.

[0003] Among them, the monocoque body has a small width and is suitable for walking in areas with high traffic in hospitals. The monocoque body is small in width and can easily enter the freight elevator or passenger elevator, which is very convenient for transportation. It only occupies part of the elevator space, and the remaining space is available for pedestrians to pass and stand. The monocoque body can be pushed in the hospital corridor without avoiding pedestrians, which is very convenient. However, the disadvantages of the monocoque body are also obvious. It can only carry one oxygen cylinder at a time. The staff responsible for transporting the oxygen cylinder need to transfer it many times, and the oxygen cylinder handling efficiency is low.

[0004] Among them, the double-barrel body has a larger vehicle width, and the double-barrel oxygen cylinders are arranged side by side, which greatly increases the width of the double-barrel body. Generally, the maximum width of the double-barrel body is more than 80cm. Such a vehicle can generally only be transported through the freight elevator, not the passenger elevator. In addition, the smaller corridors in general hospitals can only accommodate one vehicle. Pedestrians need to avoid passing by, and it is easy to bump into pedestrians during the pushing process, which is not safe. Of course, the advantage of such a double-barrel body is that it can carry two oxygen cylinders at the same time, which doubles the handling efficiency and greatly improves the handling efficiency.

[0005] Therefore, based on the advantages and disadvantages of the bodies of the above two types of transport vehicles, how to design a transport vehicle that can simultaneously meet the advantages of convenient passage and high handling efficiency to facilitate our hospital's daily transportation needs for large items such as oxygen cylinders is an urgent issue that needs to be resolved. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the utility model provides a double-layer oxygen cylinder transport vehicle, which solves the technical problem that the existing transport vehicles cannot take into account both convenient passage and high handling efficiency.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A double-layer oxygen cylinder transport vehicle comprises a frame and wheels, wherein the frame is provided with a storage space one for accommodating a single oxygen cylinder, and is characterized in that both ends of the frame in the length direction are detachably connected with a bracket one and a bracket two, wherein the bracket one and the bracket two are both located above the storage space one, and the bracket one and the bracket two are respectively provided with a support portion one and a support portion two, wherein the support portion one and the support portion two form a storage space two for accommodating a single oxygen cylinder, and the storage space one and the storage space two are stacked in the vertical direction.

[0009] This design combines the advantages of a single-cylinder body and a double-cylinder body to design a transport vehicle that can stack double oxygen cylinders up and down. The main design idea is to utilize the arrangement of the upper and lower spaces to achieve the high efficiency brought by double-cylinder transportation. In terms of width, the width difference is not much compared with the conventional single-cylinder body. The head space is exchanged for width space, so that the vehicle can be transported smoothly and efficiently in the crowded environment of the hospital.

[0010] The specific plan is as follows: The frame of the double-layer oxygen cylinder transport vehicle itself has a storage space 1 that can accommodate a single oxygen cylinder. When there is only a single oxygen cylinder, it can be directly placed in the storage space for transportation. When there are more than two oxygen cylinders, bracket 1 and bracket 2 can be quickly installed on the frame. After one of the oxygen cylinders is pushed into the storage space 1, the oxygen cylinder is then placed in the storage space 2 formed by bracket 1 and bracket 2. The two oxygen cylinders are stacked up and down and do not interfere with each other. The overall width of the transport vehicle is small and can transport a maximum of two oxygen cylinders at a time. While improving passability, the handling efficiency is doubled, which is very convenient.

[0011] In the above-mentioned double-layer oxygen cylinder transport vehicle, the bracket one and the bracket two can be plugged and connected to the vehicle frame.

[0012] The bracket one and the bracket two of the present application can be connected to the frame through a plug-in structure. When only a single oxygen cylinder is transported, the bracket one and the bracket two can be removed to reduce the load on the vehicle body. When multiple oxygen cylinders need to be transported, the bracket one and the bracket two can be quickly installed. This allows flexible switching, thereby ensuring that the transport vehicle has good passability while improving the transportation efficiency.

[0013] In the above-mentioned double-layer oxygen cylinder transport vehicle, the bracket one and the bracket two are both hinged at two ends of the vehicle frame.

[0014] This is another installation method of the bracket one and the bracket two of the present application. In this embodiment, the bracket one and the bracket two are hinged on the frame. When only a single bottle is required for transportation, the bracket one and the bracket two are rotated to a position that does not block the loading of the oxygen cylinder. When multiple bottles are required for transportation, after loading one oxygen cylinder, the bracket one and the bracket two are rotated into place to assemble the second bottle. This design can achieve the same effect as above.

[0015] In the above-mentioned double-layer oxygen cylinder transport vehicle, one end of the frame has a handle and the other end has an abutment seat, and the abutment seat is provided with a flat plate near the end of the frame. When placing the oxygen cylinder, the frame can be flipped by pushing one end of the handle so that the flat plate is against the ground.

[0016] The present application designs an abutment seat at one end of the frame, and the abutment seat is provided with a flat plate. When loading the oxygen cylinder, the handle can be pulled upward to allow the flat plate on the abutment seat at the other end to be close to the ground. In this way, the worker can turn or push the oxygen cylinder by hand to allow the bottom of the oxygen cylinder to directly enter the flat plate, and finally pull down the handle to make the oxygen cylinder lie in the accommodating space of the frame. This way of loading the oxygen cylinder does not require the oxygen cylinder to be lifted, and the loading efficiency is high and easy.

[0017] In the above-mentioned double-layer oxygen cylinder transport vehicle, sleeves with an open upper end and a closed lower end are fixed to both ends of the abutment seat in the width direction of the frame, and the second bracket has a socket part that is plug-in-pull fit with the two sleeves.

[0018] The bracket 2 of the present application is connected and fixed on the abutment seat by plugging and pulling the socket and the sleeve. Such a detachable method is simple, convenient and efficient. Since the sleeve is a cylindrical structure with an open upper end and a closed lower end, the insertion depth of the socket is limited after the socket is inserted into the sleeve. Therefore, we can design the depth of the sleeve in advance according to the diameter of the transport oxygen cylinder to meet the purpose of the upper and lower oxygen cylinders being stacked without interfering with each other.

[0019] In the above-mentioned double-layer oxygen cylinder transport vehicle, the sleeve and the socket are both square tube structures, and the length direction of the radial cross section of the sleeve and the socket when they are matched is the same as the length direction of the frame.

[0020] The sleeve and the socket part of the present application are both square tube structures, and the length direction of their radial cross-sections is consistent with the length direction of the frame. This design allows the sleeve and the socket part to be better stressed when loading oxygen cylinders. Since the frame will be lifted in the vertical direction when loading oxygen cylinders, causing the bracket two to contact the ground, the force in the vertical direction will be greater. In this way, the wider sleeve and the socket part will be better stressed.

[0021] In the above-mentioned double-layer oxygen cylinder transport vehicle, the bracket 2 includes a socket part, a support part and a base plate, the socket part is a square tube and has two roots, the support part is a bent sheet metal part, the sheet metal part is fixed on the front side of the base plate, the socket part is respectively fixed on the front side of the base plate against both ends of the sheet metal part, when the socket part is in socket fit with the sleeve, the base plate is connected to the above-mentioned flat plate, and the extension direction of the base plate is the same as that of the flat plate.

[0022] The base plate on the second bracket of the present application is used to contact the ground during loading, the support part is used to allow the bottom of the oxygen cylinder to lean against the support part laterally when the oxygen cylinder is loaded, and the socket part is used to connect and fix with the frame. This design can be more convenient when loading oxygen cylinders.

[0023] The specific loading process is as follows: first load the first oxygen cylinder, push the handle upwards to let the flat plate touch the ground so that the first oxygen cylinder can slide and be pushed into the storage space one, then slightly pull down the handle to let the oxygen cylinder lie down in the storage space one, next insert the second bracket and lift the handle to let the bottom plate touch the ground, continue to let the second oxygen cylinder slide from the bottom plate into the bottom plate, that is, the storage space two, then pull down the wrench so that both oxygen cylinders lie down in their respective spaces, and the first oxygen cylinder is limited by bracket one and bracket two. In this design, the two oxygen cylinders do not need to be lifted and placed on the transport vehicle, and the oxygen cylinders can be carried onto the vehicle through a principle similar to a lever, which is easier and more efficient.

[0024] In the above-mentioned double-layer oxygen cylinder transport vehicle, the sheet metal part is arc-shaped and matches the contour of the oxygen cylinder.

[0025] In the above-mentioned double-layer oxygen cylinder transport vehicle, the bracket 1 includes a support tube and a connecting tube, the connecting tubes have two and are arranged at intervals, the support tube is the above-mentioned support part 1, the two ends of the support tube are connected to the two connecting tubes and the three are in an H shape, and the ends of the two connecting tubes are welded with shaft sleeves, and the shaft sleeves can be inserted from the handle end.

[0026] The support tube and two connecting tubes of the present application are arranged in an H shape. When connected to the frame, the lower part of the H can limit the head of the first oxygen cylinder to prevent displacement during transportation, and the upper part of the H can limit the head of the second oxygen cylinder to prevent lateral movement. This design greatly improves the stability and safety of the transport vehicle during transfer.

[0027] In the above-mentioned double-layer oxygen cylinder transport vehicle, the bracket one has an upward state for supporting the oxygen cylinder; the bracket one has a downward state for supporting the ground.

[0028] The connection between the bracket 1 and the frame handle of the present application is a set. This design allows the bracket 1 to have two uses. One is that it is designed to load the second oxygen cylinder. The second is that when the bracket 2 is set downward on the frame, it can be used as a leg to contact the ground, allowing workers to lay the transport vehicle flat on the ground while waiting, which is easier and more adaptable.

[0029] In the above-mentioned double-layer oxygen cylinder transport vehicle, a reinforcing sheet metal part is connected between the two shaft sleeves.

[0030] In order to enhance the connection strength and the supporting strength of the bracket, a reinforced sheet metal part is designed between the two bushings to connect and fix the two. This makes the H-shaped bracket structure more stable and improves the safety of the entire vehicle.

[0031] In the above-mentioned double-layer oxygen cylinder transport vehicle, the support tube is bent to form an arc.

[0032] The curved support tube is more suitable for the body of the oxygen cylinder, so that the oxygen cylinder placed on the support tube is more stable and safer.

[0033] In the above-mentioned double-layer oxygen cylinder transport vehicle, the frame includes two main support tubes arranged at intervals, the bracket one and the bracket two are both connected to the main support tubes, and a plurality of support sheet metals arranged at intervals are also connected between the main support rods, and each support sheet metal is arc-shaped.

[0034] The supporting sheet metal can support various parts of the oxygen cylinder to prevent the oxygen cylinder from falling and improve safety.

[0035] In the above-mentioned double-layer oxygen cylinder transport vehicle, the wheels are rotatably connected to the bottom of the frame and the distance between the two wheels is greater than the distance between the two main support rods.

[0036] The width of the two wheels of the present application is designed to be slightly larger than the width of the frame, which makes the transport vehicle more stable and safer during movement and rotation.

[0037] In the above-mentioned double-layer oxygen cylinder transport vehicle, the outer sides of the two main support pipes are fixed with concave-shaped connecting sheet metals. The transport vehicle also includes straps, which can pass through the connecting sheet metals at various locations in turn and are used to bind the oxygen cylinders during transportation.

[0038] The transport vehicle of the present application is also equipped with connecting sheet metal fixed on the frame, and the connecting sheet metal at each location can pass through straps or ropes accordingly. The straps and ropes can be wrapped around and bound to the oxygen cylinder, so that the oxygen cylinder and the transport vehicle are better restrained, preventing the oxygen cylinder from moving during movement and causing the vehicle to be eccentric. This design has better stability and better safety.

[0039] Beneficial effects of the utility model: This design combines the advantages of a single-cylinder body and a double-cylinder body to design a transport vehicle that can stack and arrange double oxygen cylinders up and down. The main design idea is to utilize the arrangement of the upper and lower spaces to efficiently achieve the purpose of double-cylinder transportation. The width difference in the width direction is not much compared with a conventional single-cylinder body. The head space is exchanged for the width space, so that the vehicle can transport smoothly and efficiently in the crowded environment of the hospital. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] Embodiment 1

[0044] like Figure 1 and Figure 2 A double-layer oxygen cylinder transport vehicle shown in the figure comprises a frame 1 and wheels 6. The frame 1 comprises two main support tubes 14 arranged at intervals. A wheel bracket is installed at the bottom of the main support tube 14, and the wheel bracket is installed on the wheel bracket. The frame 1 has a storage space 11 that can accommodate a single oxygen cylinder. The frame 1 has a bracket 1 2 and a bracket 2 3 detachably connected at both ends in the length direction. The bracket 1 2 and the bracket 2 3 are both located above the storage space 1 11. The bracket 1 2 and the bracket 2 3 respectively have a support part 1 and a support part 2 32. The support part 1 and the support part 2 32 form a storage space 2 12 that can accommodate a single oxygen cylinder. The storage space 1 11 and the storage space 2 12 are stacked in the vertical direction. This design combines the advantages of a single-tube body and a double-tube body to design a transport vehicle that can stack and arrange double oxygen cylinders up and down. The main design idea is to utilize the arrangement of the upper and lower spaces to achieve efficient double-bottle transportation. In the width direction, the width difference is not much compared with the conventional single-tube body. The head space is used in exchange for the width space, so that the vehicle can be transported smoothly and efficiently in the crowded environment of the hospital. The specific scheme is as follows: The frame 1 of the double-layer oxygen cylinder transport vehicle itself has a storage space 11 that can accommodate a single oxygen cylinder. When there is only a single oxygen cylinder, it can be directly placed in the storage space 11 for transportation. When there are more than two oxygen cylinders, the bracket 1 2 and the bracket 2 3 can be quickly installed on the frame 1. After one of the oxygen cylinders is pushed into the storage space 11, the oxygen cylinder is placed in the storage space 2 12 surrounded by the bracket 1 2 and the bracket 2 3. The two oxygen cylinders are stacked up and down and do not interfere with each other. The overall width of the transport vehicle is small and can transport up to two oxygen cylinders at a time. While improving the passability, the handling efficiency is doubled, which is very convenient.

[0045] Furthermore, both the bracket 1 2 and the bracket 2 3 can be plugged and connected to the frame 1. The bracket 1 2 and the bracket 2 3 of the present application can be connected to the frame 1 through a plug-in structure. When only a single oxygen cylinder is transported, the bracket 1 2 and the bracket 2 3 can be removed to reduce the load on the vehicle body. When multiple oxygen cylinders need to be transported, the bracket 1 2 and the bracket 2 3 can be quickly installed. In this way, flexible switching is possible, which ensures that the transport vehicle has good passability while improving the handling efficiency.

[0046] Furthermore, one end of the frame 1 has a handle 13, and the other end has an abutment seat 4. The abutment seat 4 has a flat plate 41 located near the end of the frame 1. When placing the oxygen cylinder, the frame 1 can be flipped by pushing one end of the handle 13 so that the flat plate 41 is against the ground. In the present application, when loading the oxygen cylinder, the handle 13 can be pulled upward to allow the flat plate 41 on the abutment seat 4 at the other end to be against the ground. In this way, the worker can rotate or push the oxygen cylinder by hand so that the bottom of the oxygen cylinder can directly enter the flat plate 41. Finally, the handle 13 is pulled down to make the oxygen cylinder lie in the storage space 11 of the frame 1. This method of loading the oxygen cylinder does not require the oxygen cylinder to be lifted, and the loading efficiency is high and easy.

[0047] Furthermore, sleeves 42 with an open upper end and a closed lower end are fixed to both ends of the abutment seat 4 in the width direction of the frame 1, and the bracket 2 3 has a socket 31 that is plugged in and out with the two sleeves 42. The bracket 2 3 of the present application is connected and fixed on the abutment seat 4 by the plug-in fit of the socket 31 and the sleeve 42. Such a detachable method is simple, convenient and efficient. Since the sleeve 42 is a cylindrical structure with an open upper end and a closed lower end, the insertion depth of the socket 31 is limited after the socket 31 is inserted into the sleeve 42, so we can design the depth of the sleeve 42 in advance according to the diameter of the transport oxygen cylinder to meet the purpose of the upper and lower oxygen cylinders being stacked without interfering with each other. Furthermore, the abutment seat 4 has an arc-shaped inclined surface 43 that matches the oxygen cylinder, and the oxygen cylinder is more stable when it abuts against the arc-shaped inclined surface 43. The bracket 2 3 has an arc-shaped sheet metal 34 that is arranged corresponding to the arc-shaped inclined surface 43. After the socket 31 is inserted into the sleeve 42, the arc-shaped sheet metal 34 can cooperate with the arc-shaped inclined surface 43 to hold the oxygen cylinder so that the oxygen cylinder of the first layer will not shake, and the stability is better. The contact between the arc-shaped sheet metal 34 and the surface of the oxygen cylinder can also limit the installation position of the bracket 2 3.

[0048] Furthermore, the sleeve 42 and the socket 31 are both square tube structures, and the length direction of the radial cross-section when the sleeve 42 and the socket 31 are matched is the same as the length direction of the frame 1. This design allows the sleeve 42 and the socket 31 to be better stressed when loading oxygen cylinders. Since the frame 1 will be lifted in the vertical direction when loading oxygen cylinders, causing the bracket 2 3 to contact the ground, the force in the vertical direction will be greater. In this way, the wider sleeve 42 and the socket 31 will be better stressed.

[0049] Furthermore, the bracket 2 3 includes a socket part 31, a support part 2 32 and a bottom plate 33. The socket part 31 is a square tube with two roots, and the support part 2 32 is a bent sheet metal part. The sheet metal part is fixed on the front of the bottom plate 33. The socket part 31 is respectively fixed on the front of the bottom plate 33 by the two ends of the sheet metal part. When the socket part 31 and the sleeve 42 are in socket fit, the bottom plate 33 is connected with the above-mentioned flat plate 41, and the extension direction of the bottom plate 33 and the flat plate 41 is the same. The bottom plate 33 on the bracket 2 3 of the present application is used to contact with the ground during loading, and the support part is used to allow the bottom of the oxygen cylinder to be laterally against the support part when loading the oxygen cylinder, and the socket part 31 is used to be connected and fixed with the frame 1. This design can be more convenient when loading the oxygen cylinder. The specific loading process is as follows: first load the first oxygen cylinder, push the handle 13 upwards to let the flat plate 41 touch the ground and stick to the ground so that the first oxygen cylinder can slide and be pushed into the storage space 11, then slightly pull down the handle 13 to let the oxygen cylinder lie down in the storage space 11, then insert the bracket 23 and lift the handle 13 to let the bottom plate 33 touch the ground, and continue to let the second oxygen cylinder slide from the bottom plate 33 to the bottom plate 33, that is, the storage space 2 12, and then pull down the handle 13 so that both oxygen cylinders lie down in their respective spaces, and the first oxygen cylinder is limited by the bracket 12 and the bracket 23. In this design, the two oxygen cylinders do not need to be lifted and put into the transport vehicle, and the oxygen cylinders can be carried onto the vehicle by a lever-like principle, which is easier and more efficient. Preferably, the sheet metal is arc-shaped and fits the contour of the oxygen cylinder.

[0050] Furthermore, the bracket 2 includes a support tube 22 and a connecting tube 21. The connecting tube 21 has two and is arranged at intervals. The support tube 22 is the above-mentioned support part 1. The two ends of the support tube 22 are connected to the two connecting tubes 21 and the three are in an H shape. The ends of the two connecting tubes 21 are welded with a sleeve 23, and the sleeve 23 can be inserted from the handle 13 end. A hole position and a bolt plug-in member 5 are also designed at one end of the handle of the frame 1. After the sleeve 23 is moved into place, the two holes on the same handle are respectively located on both sides of the sleeve 23. Inserting or screwing the bolt in can limit the sleeve 23. Figure 1As shown. The support tube 22 and two connecting tubes 21 of the present application are arranged in an H shape. When connected to the frame 1, the lower part of the H can limit the head of the first oxygen cylinder to prevent it from shifting during transportation, and the upper part of the H can limit the head of the second oxygen cylinder to prevent lateral movement. This design greatly improves the stability and safety of the transport vehicle during transfer. When the bracket 2 is set upward, it is used to support the oxygen cylinder; when the bracket 2 is downward, it is used to contact the ground to support the frame 1. The connection method between the bracket 2 of the present application and the handle 13 of the frame 1 is a set. This design makes the bracket 2 have two uses. One is to load the second oxygen cylinder. The second is that when the bracket 23 is downwardly mounted on the frame 1, it can be used as a leg to contact the ground, allowing workers to lay the transport vehicle flat on the ground while waiting, which is more relaxed and more adaptable.

[0051] Furthermore, a reinforcing sheet metal part 24 is connected between the two shaft sleeves 23. In order to strengthen the connection strength and the support strength of the bracket 2, a reinforcing sheet metal part 24 is designed between the two shaft sleeves 23 to connect and fix the two, so that the H-shaped bracket 2 structure is more stable and the safety of the whole vehicle is better. Preferably, the support tube 22 is bent to form an arc. The bent support tube 22 is more suitable for the body of the oxygen cylinder, so that the oxygen cylinder placed on the support tube 22 is more stable and safer.

[0052] Furthermore, the bracket 1 2 and the bracket 2 3 are both connected to the main support tube 14, the frame 1 includes a chassis frame and two main support tubes 14 that are parallel to each other and spaced apart, the wheels 6 are mounted on the chassis frame, the two main support tubes 14 are welded to the top of the chassis frame, and a plurality of support sheet metals 15 arranged at intervals are connected between the main support rods, each support sheet metal 15 is arc-shaped. The support sheet metal 15 can support various parts of the oxygen cylinder to prevent the oxygen cylinder from falling and improve safety.

[0053] Furthermore, the wheels 6 are rotatably connected to the bottom of the frame 1 and the distance between the two wheels 6 is greater than the distance between the two main support rods. The width of the two wheels 6 of the present application is designed to be slightly larger than the width of the frame 1, so that the transport vehicle is more stable and safer during movement and rotation.

[0054] Furthermore, the outer sides of the two main support tubes 14 are fixed with a concave-shaped connecting sheet metal 16, and the transport vehicle also includes a strap, which can pass through the connecting sheet metal 16 at various locations in sequence, and is used to bind the oxygen cylinder during transportation. The transport vehicle of the present application is also fixed with a connecting sheet metal 16 on the frame 1, and the connecting sheet metal 16 at various locations can pass through a strap or a binding rope, and the strap and the binding rope can be wrapped around and bound to the oxygen cylinder, so that the oxygen cylinder and the transport vehicle are better constrained, and the oxygen cylinder is prevented from moving during movement and causing the vehicle to be eccentric. This design has better stability and better safety.

[0055] Embodiment 2

[0056] This is another installation method of the bracket 1 2 and the bracket 2 3 of the present application. The other structures of the present application are the same as those of the embodiment 1, except that: in the present embodiment, the bracket 1 2 and the bracket 2 3 are hinged to the frame 1 through a hinged member. When the hinged member is in a vertical downward position, it is a conventional leg structure, which is mainly used for supporting the ground to keep the trolley in a flat state when the loaded oxygen cylinder needs to stop and rest. The leg rotates to the top and the leg slightly tilts forward to form a certain angle, and the hinged member has the ability to limit, and the leg can be limited to maintain the angle when it swings to a certain angle. The rear of the trolley can be equipped with a double-layer baffle plate, and after the oxygen cylinders of one layer are loaded, the baffle plate can be installed to stack the oxygen cylinders of the second layer. When there is only a single-bottle transportation demand, the bracket 1 2 and the bracket 2 3 are rotated to a position that does not block the loading of the oxygen cylinders. When there is a demand for multiple bottles of transportation, after loading one bottle of oxygen cylinders, the bracket 1 2 and the bracket 2 3 are rotated to the position to assemble the second bottle. This design can achieve the same effect as above.
