Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in conventional transport vehicles, the adapter was stored in a separate box from the valve body. Therefore, when connecting the adapter to the supply and discharge valve, it was necessary to remove the adapter from the box and transport it to the valve body, and there was a problem that the worker could be injured if the adapter fell during transport.

[0006] This invention was made to solve the above-mentioned problems, and aims to provide a transport vehicle that can reduce the effort required to transport the adapter when connecting it to a supply / discharge valve. [Means for solving the problem]

[0007] To achieve this objective, the transport vehicle of the present invention is a liquid transport vehicle. , gas or solid The system comprises a tank for loading cargo, a supply / discharge valve for supplying cargo to the tank or discharging cargo from the tank, and a box-shaped valve body in which the supply / discharge valve is housed. Inside the valve body is a storage compartment for storing an adapter that can be attached to or detached from the supply / discharge valve and the source or destination of the cargo. The adapter consists of a cylindrical pipe portion and flange-shaped flange portions formed at both ends of the pipe portion. The storage compartment is provided with fixing means for fixing the pipe portion of the adapter to the storage compartment. [Effects of the Invention]

[0008] According to the transport vehicle described in claim 1, a storage compartment for the adapter is provided inside the valve body, so that the adapter can be stored inside the valve body where the supply and discharge valves are housed. This has the effect of reducing the effort required to transport the adapter, as it is not necessary to bring the adapter from outside the valve body when connecting it to the supply and discharge valves. Furthermore, the storage compartment is provided with fixing means for fixing the pipe portion of the adapter to the storage compartment. This prevents the adapter from detaching from the storage compartment and scattering due to vibrations caused by the transport vehicle's movement, thus preventing the adapter from damaging the supply and discharge valves or other equipment inside the valve body.

[0009]

[0010] The transport vehicle according to claim 2 provides the following effects in addition to those of the transport vehicle according to claim 1. The fixing means is formed in an elongated shape, and the pipe portion of the adapter is fixed to the storage unit by placing the elongated fixing means over the pipe portion of the adapter which is placed on the mounting surface of the storage unit. Therefore, not only can one adapter be fixed to the storage unit by placing the fixing means over its pipe portion, but multiple adapters can be fixed to the storage unit together by placing the same fixing means over their pipe portions. As a result, there is no need to provide a device to fix the pipe portion of each adapter stored in the storage unit, which has the effect of maintaining the space efficiency of the storage unit.

[0011] The transport vehicle according to claim 3 provides the following effects in addition to those of the transport vehicle according to claim 2. The storage section is formed in a box shape with walls erected on the mounting surface, so that debris, mud, etc. that may be scattered from outside the storage section are prevented from entering the mounting surface by the mounting surface and walls of the storage section. This has the effect of preventing damage or contamination of the adapter stored in the storage section. Furthermore, the walls of the storage section are erected in a position where the walls and the adapter do not come into contact even when the adapter, which is suspended on the fixing means, moves relative to the mounting surface. This also has the effect of preventing damage to the adapter by the walls of the storage section.

[0012] The transport vehicle according to claim 4 provides the following effects in addition to those of the transport vehicle according to claim 2 or 3: Two through holes are formed in the mounting surface, and the fixing means are stretched across the mounting surface of the storage unit by being inserted through the two through holes from the back side of the mounting surface of the storage unit. This has the effect of providing the fixing means without having to install a separate device (for example, one for fixing the fixing means to the mounting surface) on the mounting surface. In addition, since the fixing means are provided by being inserted through the through holes, it also has the effect of being able to easily replace damaged or deteriorated fixing means.

[Modes for carrying out the invention]

[0014] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. First, the configuration of the tank truck 1 in this embodiment will be described with reference to Figure 1. Figure 1(a) is a side view of the tank truck 1. In Figure 1, arrow UD indicates the vertical direction of the tank truck 1, arrow FB indicates the front-to-back direction of the tank truck 1, and arrow LR indicates the left-to-right direction of the tank truck 1. The same applies to Figures 2 and beyond.

[0015] The tank truck 1 is a vehicle (transport vehicle) that transports a load such as LPG (liquefied petroleum gas) as a liquid, and includes a plurality of wheels 2, a chassis frame 3 supported by the plurality of wheels 2 and extending along the front-rear direction of the tank truck 1, a sub-frame 4 provided on the chassis frame 3, a tank 5 mounted on the chassis frame 3 via the sub-frame 4 and for loading the load, and a valve box 6. The valve box 6 is a rectangular parallelepiped and box-shaped member provided at the lower part on the side of the tank 5. A door that can be opened is provided on the front surface of the valve box 6. The inside of the valve box 6 will be described with reference to FIG. 1(b).

[0016] FIG. 1(b) is a front view of the valve box 6. In FIG. 1(b), it shows the state where the door of the valve box 6 is removed in FIG. 1(a). Note that the front view direction of the valve box 6 in the present embodiment is the same as the side view direction of the tank truck 1. Inside the valve box 6, mainly, a liquid valve 6a and a gas valve 6b, and an operating device 6c operated during the loading and unloading operation of the load are provided.

[0017] The liquid valve 6a is a valve (supply and discharge valve) that supplies liquid to the tank 5 or discharges liquid from the tank 5, and is provided at the lower part inside the valve box 6. The gas valve 6b is a valve (supply and discharge valve) that supplies gas to the tank 5 or discharges gas from the tank 5, and is provided at the lower part inside the valve box 6 and on the right side (i.e., the side in the direction of arrow B) in the front view of the liquid valve 6a. When supplying the load to the tank 5, the gas in the tank 5 is discharged from the gas valve 6b, or when discharging the load from the tank 5, gas is supplied to the gas valve 6b.

[0018] The liquid valve 6a and the gas valve 6b are each provided with connection ports 6a1 and 6b1, and detachable covers 6a2 and 6b2 for protecting the connection ports 6a1 and 6b1. By removing the covers 6a2 and 6b2 from the connection ports 6a and 6b1 and connecting the connection ports 6a1 and 6b1 to the connection ports (not shown) at the supply source or discharge destination of the load, the supply of the load to the tank 5 or the discharge of the load from the tank 5 is performed.

[0019] However, the shapes and sizes (for example, the diameters of the connection ports) of these connection ports 6a1 and 6b1 may differ from those of the connection ports at the supply source or payout destination of the loaded items. In that case, a detachable adapter 7 (see FIG. 2) for converting the shape of the connection port or the like is connected to the connection ports 6a1 and 6b1. In the present embodiment, a storage box 6d for storing the adapter 7 is provided on the right side of the gas valve 6b in the front view of the valve box 6. The details of the adapter 7 and the storage box 6d will be described with reference to FIGS. 2 and 3.

[0020] FIG. 2(a) is a front view of the storage box 6d, FIG. 2(b) is a top view of the storage box 6d in the direction of arrow IIb in FIG. 2(a), and FIG. 3 is a cross-sectional view taken along the cross-section line III-III in FIG. 2(a).

[0021] As shown in FIGS. 2(a) and 2(b), the storage box 6d is a box-shaped member (storage portion) with an open top surface. Specifically, the storage box 6d includes a placement surface 6d1 that is rectangular in a top view and forms the bottom surface on which the adapter 7 is placed, and a wall 6d2 that stands along the edge of the placement surface 6d1. The height of the wall 6d2 is formed higher than the radius of the second flange portion 7c of the adapter 7 having the largest diameter among the adapters 7 (hereinafter referred to as the "adapter 7 with the largest diameter").

[0022] Since the storage box 6d is formed in a box shape and the height of the wall 6d2 is formed higher than the radius of the second flange portion 7c of the adapter 7 with the largest diameter, dust, mud, etc. that fly in from the outside of the storage box 6d when the door of the valve box 6 is opened during the payout operation of the loaded items or the like are suppressed by the wall 6d2 from entering the inside of the storage box 6d, specifically, onto the placement surface 6d1 on which the adapter 7 is placed. Thereby, it is possible to prevent the adapter 7 stored in the storage box 6d from being damaged or contaminated. Further, since the wall 6d2 is formed higher than the radius of the second flange portion 7c of the adapter 7 with the largest diameter, even when a belt 6d3 (described later) fixed to the adapter 7 comes off, it is possible to prevent the adapter 7 from detaching from the storage box 6d.

[0023] The adapter 7 stored in the storage box 6d consists of a cylindrical pipe portion 7a and flange-shaped first flange portion 7b and second flange portion 7c formed at both ends of the pipe portion 7a. The first flange portion 7b and the second flange portion 7c are each formed with a first connection port 7b1 and a second connection port 7c1, respectively, which communicate with the pipe portion 7a.

[0024] The adapter 7 is placed horizontally on the mounting surface 6d1 of the storage box 6d, with its first connection port 7b1 and second connection port 7c1 facing the front-to-back direction (horizontal direction) of the tank truck 1. This makes it difficult for the mounting surface 6d1 to come into contact with the first connection port 7b1 and the second connection port 7c1, thereby preventing damage to the first connection port 7b1 and the second connection port 7c1 from the mounting surface 6d1.

[0025] The distance between the walls 6d2 facing each other in the front-rear direction of the tank truck 1 in the storage box 6d is set to be greater than the sum of the total length of the adapter 7 with the longest overall length (hereinafter referred to as "the longest adapter 7") and the distance between the first flange portion 7b and the second flange portion 7c of that longest adapter 7.

[0026] Furthermore, the mounting surface 6d1 is formed so that three adapters 7 with the largest diameter, each with the first connection port 7b1 and the second connection port 7c1 positioned horizontally in the front-to-back direction of the tank truck 1, can be arranged side by side in the left-to-right direction of the tank truck 1. This allows up to three adapters 7 to be placed together in one storage box 6d, thus reducing the cost and effort required to provide storage boxes 6d compared to the case where a storage box 6d is provided for each adapter 7 in the valve body 6. Note that the maximum number of adapters 7 to be placed on the mounting surface 6d1 is not limited to three; it may be three or more, or three or fewer.

[0027] Furthermore, by positioning the adapter 7 on the mounting surface 6d1 with its first connection port 7b1 and second connection port 7c1 facing the front-rear direction of the tank truck 1, the rolling direction of the first flange portion 7b and second flange portion 7c of the adapter 7 coincides with the left-right direction of the tank truck 1 on the mounting surface 6d1, that is, the direction perpendicular to the direction of travel when the tank truck 1 is moving in a straight line. Therefore, the inertial force caused by the straight-line movement or stopping of the tank truck 1 can suppress the rolling of the first flange portion 7b and second flange portion 7c on the mounting surface 6d1.

[0028] The storage box 6d is provided with a belt 6d3 for securing the adapter 7. The belt 6d3 is a strip-shaped polypropylene component (securing means) and is provided by inserting it through two through holes 6d4 formed in the mounting surface 6d1 from the underside of the mounting surface 6d1. The adapter 7 is secured to the storage box 6d by placing the belt 6d3 over the pipe portion 7a of the adapter 7 which is placed on the mounting surface 6d1 and then locking it with the belt 6d3.

[0029] Since the belt 6d3 is formed in a strip shape, not only can one adapter 7 be bundled with one belt 6d3 and fixed to the storage box 6d, but multiple adapters 7 can also be bundled with one belt 6d3 and fixed together to the storage box 6d. Therefore, it is not necessary to provide multiple fixing devices for each adapter 7 stored in the storage box 6d. Figures 2(b) and 3 show the case where the pipe sections 7a are bundled with the belt 6d3 with space between adjacent adapters 7, but this is not the only case, and the pipe sections 7a of adjacent adapters 7 may also be bundled with the belt 6d3 with the first flange sections 7b or second flange sections 7c in contact with each other.

[0030] Furthermore, since the adapter 7 is fixed in place by being sandwiched between the belt 6d3 and the mounting surface 6d1 of the storage box 6d, it is possible to prevent the adapter 7 from detaching from the storage box 6d due to vertical vibrations caused by the movement of the tank truck 1.

[0031] Furthermore, by making the belt 6d3 a strip, the contact area between the belt 6d3 and the adapter 7 can be increased compared to when it is a string, allowing the adapter 7 to be securely fixed to the storage box 6d. Also, since the belt 6d3 is installed by inserting it through the through hole 6d4, damaged or deteriorated belts 6d3 can be easily replaced.

[0032] These two through holes 6d4 are drilled approximately in the center of the mounting surface 6d1 in the left-right direction. As described above, the distance between the opposing walls 6d2 on the mounting surface 6d1 in the left-right direction is set to be greater than the total length of the longest adapter 7 plus the distance between the first flange portion 7b and the second flange portion 7c of the longest adapter 7. That is, the distance between the through holes 6d4 and the left-right side walls 6d2 is greater than the total length of the longest adapter 7 plus the distance between the first flange portion 7b and the second flange portion 7c of the longest adapter 7.

[0033] By providing the wall 6d2 and through-hole 6d4 in this position, even if the belt 6d3 inserted through the through-hole 6d4 is bundled at a position shifted toward the first flange portion 7b side or the second flange portion 7c side of the pipe portion 7a, or even if the adapter 7 moves relative to the mounting surface 6d1 due to vibrations caused by the movement of the tank truck 1, the first flange portion 7b or the second flange portion 7c is less likely to come into contact with the wall 6d2 of the storage box 6d. Therefore, it is possible to prevent the first flange portion 7b or the second flange portion 7c, or the first connection port 7b1 or the second connection port 7c1 formed therein, from coming into contact with the wall 6d2 and being damaged.

[0034] Furthermore, since the first flange portion 7b and the second flange portion 7c are formed at both ends of the pipe portion 7a, even if the belt 6d3 stretched across the pipe portion 7a shifts towards the first flange portion 7b or the second flange portion 7c, the belt 6d3 is configured to catch on the first flange portion 7b or the second flange portion. This makes it difficult for the pipe portion 7a and the adapter 7 to detach from the belt 6d3.

[0035] The belt 6d3 is equipped with detachable side-release buckles 6d5 and 6d6 (fixing parts) at both ends. With buckles 6d5 and 6d6 detached, the belt 6d3 is placed over the pipe section 7a, and then buckles 6d5 and 6d6 are fitted together to secure the adapter 7 to the belt 6d3.

[0036] As described above, the tank truck 1 of this embodiment is provided with a storage box 6d for storing the adapter 7 inside the valve body 6, which houses the liquid valve 6a and the gas valve 6b. This eliminates the need to transport the adapter 7 from outside the valve body 6 when connecting it to the liquid valve 6a and the gas valve 6b, thus reducing the effort involved.

[0037] The storage box 6d is equipped with a belt 6d3 for securing the adapter 7. This prevents the adapter 7 from detaching from the storage box 6d due to vibrations caused by the movement of the tank truck 1, thereby preventing damage to the liquid valve 6a, gas valve 6b, operating device 6c, etc., caused by the adapter 7.

[0038] Although the present invention has been described above based on embodiments, it can be easily inferred that the present invention is not limited in any way to the embodiments described above, and that various improvements and modifications are possible without departing from the spirit of the present invention.

[0039] In the above embodiment, a box-shaped storage box 6d was given as an example of a storage unit. However, it is not limited to this, and for example, the storage unit may be constructed by omitting a part of the wall 6d2 from the storage box 6d, or by omitting all of the wall 6d2 and consisting only of the mounting surface 6d1.

[0040] In the above embodiment, a belt 6d3 is exemplified as the fastening means, but the fastening means may be made of other members formed in the shape of a strip, such as a band made of synthetic rubber. Since such a band is elastically deformable, the length of the belt 6d3 can be adjusted even if the length adjustment mechanism in the buckle 6d5 is omitted. Furthermore, the fastening means is not limited to the belt 6d3 and the band, but may also be a rope, fishing line, or a string-like or elongated member made of metal such as iron, such as a chain or wire.

[0041] Alternatively, instead of using a strip or string as the fixing means, the adapter 7 may be fixed to the storage box 6d by other means. For example, as shown in Figures 4(a) and 4(b), fixing holes 6d30 may be drilled in the mounting surface 6d1, into which the lower parts of the first flange portion 7b and the second flange portion 7c of the adapter 7 can be fitted, and the adapter 7 may be fixed to the fixing holes 6d30 by fitting the first flange portion 7b and the second flange portion 7c into the fixing holes 6d30.

[0042] Alternatively, instead of the fixing hole 6d30, as shown in Figure 4(c), a fixing hole 6d31 may be formed in the mounting surface 6d1, which is an arc-shaped recess into which the lower parts of the first flange portion 7b and the second flange portion 7c can be fitted. The adapter 7 may then be fixed to the fixing hole 6d31 by fitting the first flange portion 7b and the second flange portion 7c into the fixing hole 6d31.

[0043] In these cases, it is preferable to set the width of the fixing holes 6d30 and 6d31 (the vertical dimension in Figure 4(a)) to be greater than the width of the second flange portion 7c of the adapter 7 with the largest diameter, and to set the length of the fixing holes 6d30 and 6d31 on the longitudinal side (the horizontal dimension in Figure 4(a)) to be smaller than the radius of the adapter 7 with the smallest diameter of the second flange portion 7c among the adapters 7.

[0044] Alternatively, as shown in Figures 5(a) and (b), a fixing device 6d32 made of two leaf springs may be provided on the mounting surface 6d1, and the adapter 7 may be fixed to the storage box 6d by sandwiching the adapter 7 between the two leaf springs. Specifically, curved portions 6d32a and 6d32b are formed approximately in the center of each of the two leaf springs in the fixing device 6d32, curved to match the shape of the outer circumference of the pipe portion 7a of the adapter 7 with the largest diameter. The adapter 7 is fixed to the fixing device 6d32 by fitting the pipe portion 7a of the adapter 7 between these curved portions 6d32a and 6d32b. In addition, guide portions 6d32c and 6d32d are formed at the upper ends of the two leaf springs in the fixing device 6d32, respectively, which are bent outwards. These guide portions 6d32c and 6d32d allow the pipe portion 7a of the adapter 7 to be easily inserted between the two leaf springs.

[0045] Furthermore, as shown in Figures 5(c) and 5(d), a fixing device 6d33 may be provided on the mounting surface 6d1, in which a lower fixing part 6d33a constituting the lower part and an upper fixing part 6d33b constituting the upper part are connected by a hinge 6d33c, and the adapter 7 may be fixed to the storage box 6d by sandwiching the pipe part 7a between the lower fixing part 6d33a and the upper fixing part 6d33b. Specifically, recesses 6d33d and 6d33e are formed in the overlapping portions of the lower fixing part 6d33a and the upper fixing part 6d33b, respectively, which are indentations formed along the shape of the outer circumference of the pipe part 7a of the adapter 7 with the largest diameter, and the adapter 7 is fixed to the fixing device 6d33 by sandwiching the pipe part 7a between the recesses 6d33d and 6d33e.

[0046] When the pipe portion 7a of the adapter 7 is fixed by the curved portions 6d32a and 6d32b of the fixing device 6d32 in Figures 5(a) and 5(b), and by the lower fixing portion 6d33a and upper fixing portion 6d33b of the fixing device 6d33 in Figures 5(c) and 5(d), the first flange portion 7b and the second flange portion 7c may be configured to not come into contact with the mounting surface 6d1. This prevents the first flange portion 7b and the second flange portion 7c from being damaged by the mounting surface 6d1.

[0047] Furthermore, to prevent damage to the wall 6d2 and adapter 7 due to deterioration or breakage of fastening means such as the belt 6d3, it is preferable to attach shock-absorbing material such as synthetic rubber or sponge to the inside of the wall 6d2.

[0048] In the above embodiment, side-release buckles 6d5 and 6d6 were used as examples of fastening parts for the belt 6d3, but the invention is not limited to these. Other types of buckles, such as ring-shaped buckles, may be used, or fastening mechanisms other than buckles may be used as fastening parts. Alternatively, the fastening parts such as buckles 6d5 and 6d6 may be omitted from the belt 6d3, and the ends of the belt 6d3, which is stretched over the adapter 7 and bundled together, may be tied and secured by a worker.

[0049] In the above embodiment, a through hole 6d4 is provided in the mounting surface 6d1, and a strip-shaped belt 6d3 is inserted through the through hole 6d4 to provide the belt 6d3 to the mounting surface 6d1. However, the embodiment is not limited to this, and for example, instead of a through hole 6d4, a fastening device such as a clip that detachably holds and secures the end of the belt 6d3 may be provided on the mounting surface 6d1, and the end of the belt 6d3 may be held in place by the fastening device to provide the belt 6d3 to the mounting surface 6d1. Alternatively, the belt 6d3 may be stretched across the upper end of the wall 6d2 of the storage box 6d, and the adapter 7 may be configured to not detach from the storage box 6d by the stretched belt 6d3.

[0050] In the above embodiment, three linear adapters 7 are fixed with a belt 6d3, but the shape of the adapters 7 is not limited to this. For example, a pipe section 7a bent at a 90-degree angle in the center may be used as the adapter 7, or other shapes may be used. Also, the number of adapters 7 fixed with the belt 6d3 may be three or less, or three or more.

[0051] In the above embodiment, a tank truck 1 for transporting liquid cargo was used as the transport vehicle. However, the invention is not limited to this, and may be applied to tank trucks transporting gases or solids, or to other transport vehicles or vehicles such as bulk tankers.

[0052] The numerical values ​​listed in the above embodiment are merely examples, and it is certainly possible to use other numerical values. [Explanation of Symbols]
