Containers and vehicles

Abstract

To provide a container body and a vehicle capable of suppressing the diffusion of rainwater into an equipment room. [Solution] A container body 20 attached to a tank truck 100 includes a tank 4, a discharge pipe 6 connected to the tank 4, an equipment room 5 into which the discharge pipe 6 is introduced and a mounting hole 5b formed in the roof 5a, a cylindrical body 7 fitted into the mounting hole 5b of the equipment room 5 and into which the discharge pipe 6 is inserted with a gap on the inner periphery, and a canopy 8 covering a vent hole 7a formed on the upper end of the cylindrical body 7. The container body 20 is attached to surround the outer periphery of the discharge pipe 6 and is formed in a container shape with an open top when attached. As a result, even if rainwater enters through the vent hole 7a and drips down the outer periphery of the discharge pipe 6, the container body 20 can receive the rainwater. This prevents rainwater from diffusing inside the equipment room 5.

Description

[Technical Field]

[0001] The present invention relates to a container body and a vehicle, and more particularly to a container body and a vehicle that can suppress the diffusion of rainwater into an equipment room. [Background technology]

[0002] For example, Patent Document 1 describes a technique for releasing vaporized gas in tank 10 to the atmosphere through gas release valve 403 and safety valve 405 when the internal pressure of tank 10 exceeds a specified pressure. A release pipe (piping) for releasing such vaporized gas is introduced from the tank into the equipment room, and its tip protrudes outside from the roof of the equipment room. An example of an equipment room is equipment room 9 of tank truck 1 described in Patent Document 2.

[0003] Because the tip of the discharge pipe protruding outside the equipment room may allow rainwater or foreign objects to get in, it is common for the tip of the discharge pipe to be covered with a canopy. One possible structure for fixing this type of discharge pipe to the equipment room is to fit the tip of the discharge pipe into a mounting hole in the roof of the equipment room. However, this type of structure requires high machining precision for the discharge pipe and the equipment room, as the mounting hole and the tip of the discharge pipe must be aligned. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2013-032839 A (for example, paragraph 0071, Figure 6) [Patent Document 2] JP 2023-044185 A (for example, paragraph 0043, Figure 5) Summary of the Invention [Problem to be solved by the invention]

[0005] Therefore, the applicant came up with a structure in which a cylindrical body with an inner diameter larger than the outer diameter of the discharge pipe is fitted into the mounting hole and fixed, and the tip of the discharge pipe is inserted into the inner periphery of the cylindrical body. With this structure, the required machining precision for the discharge pipe and the equipment chamber can be relaxed by the amount of the gap formed between the inner periphery of the cylindrical body and the outer periphery of the discharge pipe.

[0006] By covering the periphery of the ventilation hole formed on the outer peripheral surface of the upper end of the cylinder (the part that protrudes outside the equipment room) with a cap, the vaporized gas released from the discharge pipe can be released into the atmosphere through the ventilation hole, while the cap can prevent foreign matter from entering through the ventilation hole.

[0007] However, if a gap is formed between the inner peripheral surface of the cylinder and the outer peripheral surface of the discharge pipe, for example, in strong winds and rain, rainwater that seeps in through the ventilation holes in the cylinder may adhere to the outer peripheral surface of the discharge pipe, causing the problem that rainwater that drips down the outer peripheral surface of the discharge pipe may spread inside the equipment room.

[0008] The present invention has been made to solve the above-mentioned problems, and aims to provide a container body and a vehicle that can prevent rainwater from diffusing into an equipment room. [Means for solving the problem]

[0009] In order to achieve this object, the container body of the present invention is a container body to be attached to a vehicle, which comprises a tank, piping connected to the tank, an equipment room into which the piping is introduced and in which an attachment hole is formed in the roof, a cylindrical body that is fitted into the attachment hole of the equipment room and into which the piping is inserted with a gap on the inner periphery, and a cap that surrounds an air vent formed on the outer surface of the upper end of the cylindrical body, and which is attached so as to surround the outer surface of the piping, and when attached, is formed into a container shape with an open top side.

[0010] The vehicle of the present invention is a vehicle comprising a tank, piping connected to the tank, an equipment room into which the piping is introduced and in which an attachment hole is formed in the roof, a cylindrical body that is fitted into the attachment hole of the equipment room and into which the piping is inserted with a gap on the inner periphery, and a cap that surrounds an air vent formed on the outer surface of the upper end side of the cylindrical body, and the container body of the present invention is attached to the piping. [Effects of the Invention]

[0011] According to the container body of claim 1 and the vehicle of claim 8, the container body is attached so as to surround the outer circumferential surface of the piping, and in this attached state is formed into a container shape with an open top. As a result, even if rainwater enters through the vent holes of the cylindrical body and drips down the outer circumferential surface of the piping, the container body can receive the rainwater. This has the effect of preventing the rainwater from diffusing inside the equipment room.

[0012] According to the container body of claim 2, in addition to the effect of the container body of claim 1, since it is provided with a first receiving member and a second receiving member that sandwiches the piping between the first receiving member and the second receiving member to form the container shape, the first receiving member and the second receiving member (hereinafter collectively referred to as "each receiving member") can be attached from the side of the piping, thereby providing the effect that each receiving member can be attached to the piping in a state where it is inserted into the inner periphery of the cylindrical body.

[0013] According to the container body of claim 3, in addition to the effect of the container body of claim 2, a support is provided which is fastened to a bracket fixed to the lower end side of the cylindrical body by a first fastening member. Each receiving member is fastened to the support by a second fastening member, so each receiving member can be attached to an existing bracket provided on the tank truck. Therefore, there is an effect that it is not necessary to provide separate parts for attaching each receiving member.

[0014] According to the container body of claim 4, in addition to the effect of the container body of claim 3, the first fastening members fasten the pipe, bracket, and support together on both sides of the pipe, so that the pipe and support can be stably fixed to the bracket. This makes it difficult for the pipe and each support member to shift relative positions, and has the effect of suppressing water leakage from the mating surfaces of the pipe and each support member.

[0015] The container body of claim 5 achieves the following effect in addition to the effect achieved by the container body of claim 4. The support comprises a first support to which the first receiving member is fastened and fixed, and a second support to which the second receiving member is fastened and fixed. The first support and second support, which sandwich the pipe and bracket, are fastened together by the first fastening member, so the fastening force of the first fastening member can be applied in the direction in which the receiving members sandwich the pipe. This makes it less likely for gaps to occur at the mating surfaces of the pipe and each receiving member, thereby preventing water leakage from those mating surfaces.

[0016] According to the container body of claim 6, in addition to the effects of the container body of claim 5, the first support includes a first fastened plate that is placed on the bracket and fastened and fixed by the first fastening member, and a first fixing plate that is provided approximately perpendicular to the lower end of the first fastened plate and to which the first receiving member is fastened and fixed, so that the rigidity of the first support (first fastened plate) against bending in the fastening direction of the first fastening member can be ensured by the first fixing plate. Also, the second support includes a second fastened plate that sandwiches the piping between it and the first fastened plate and is fastened and fixed by the first fastening member, and a second fixing plate that is provided approximately perpendicular to the lower end of the second fastened plate and to which the second receiving member is fastened and fixed, so that the rigidity of the second support (second fastened plate) against bending in the fastening direction of the first fastening member can be ensured by the second fixing plate.

[0017] By ensuring the rigidity of the first and second supports in the fastening direction of the first fastening member, the pipes and brackets can be firmly clamped by the supports. This makes it difficult for the pipes and the support members to shift relative to each other. This reduces the likelihood of gaps occurring at the mating surfaces of the pipes and the support members, thereby effectively preventing water leakage from those mating surfaces.

[0018] According to the container body of claim 7, in addition to the effect of the container body of claim 6, the second support is provided at a position substantially perpendicular to the upper end of the second fastened plate and has an upper plate facing the second fixing plate, and the upper plate is overlapped on the lower surface of the cylindrical body, so that the relative positional deviation of the piping and the cylindrical body in the vertical direction can be restricted by the contact between the cylindrical body and the upper plate. This makes it possible to suppress vertical displacement (vibration) of each receiving member, and therefore has the effect of suppressing rainwater collected on each receiving member from scattering inside the equipment room.

[0020] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. First, the overall configuration of a tank truck 100 will be described with reference to Fig. 1. Fig. 1 is a side view of a tank truck 100 according to one embodiment of the present invention. Fig. 1 also shows a schematic diagram of the piping structure of a discharge pipe 6 connected to a tank 4.

[0021] 1, the tank truck 100 is configured as a vehicle that transports liquefied gas (for example, liquid nitrogen or LNG) and has a plurality of wheels 1. A chassis frame 2a that forms the framework of a vehicle body 2 is supported by the wheels 1.

[0022] The chassis frame 2a is a frame that extends in the front-to-rear direction of the vehicle body (left-to-right direction in FIG. 1), and a cab 2b that serves as a driver's seat is located at the front end of the chassis frame 2a. A tank 4 is supported (mounted) on the chassis frame 2a, which is located rearward of the cab 2b, via subframes 3. The subframes 3 are frames that extend in the front-to-rear direction, and although not shown, the tank 4 is supported on a pair of subframes 3 that are aligned in the left-to-right direction of the vehicle body (perpendicular to the plane of FIG. 1).

[0023] Before the tank 4 is mounted on the chassis frame 2a, the subframe 3 is fixed to the tank 4 by welding or the like, and the tank 4 is mounted on the chassis frame 2a by fixing the subframe 3 to the chassis frame 2a with a fixing device (not shown) or by welding.

[0024] The tank 4 is a cylindrical tank for carrying liquefied gas. An equipment room 5 is supported on the chassis frame 2a (subframe 3), which extends rearward from the tank 4, and the rear end of the tank 4 is covered by this equipment room 5. The equipment room 5 is formed in a box shape with an opening and closing door (not shown) on the rear side, and inside the equipment room 5 are provided operating devices and meters (neither of which is shown) that are operated during liquefied gas loading and unloading operations.

[0025] A release pipe 6 is connected to the rear of the tank 4 via a safety valve and other piping (not shown). The release pipe 6 is a pipe for releasing vaporized gas (evaporated liquefied gas) in the tank 4 into the atmosphere when the internal pressure in the tank 4 exceeds a specified value. The safety valve that controls the opening and closing of the release pipe 6 may be one that opens and closes by operator operation, or may be one that opens automatically when the internal pressure in the tank 4 exceeds a specified value.

[0026] The discharge pipe 6 is introduced from the tank 4 into the equipment room 5, and the tip of the discharge pipe 6 protrudes from the roof 5a of the equipment room 5 (see the enlarged portion in Figure 1). A cylindrical body 7 and a cap 8 that cover the tip of the discharge pipe 6 are attached to the roof 5a. The attachment structure of these cylindrical body 7 and cap 8 will be described with reference to Figure 2. Figure 2 is a partially enlarged cross-sectional view of a tank truck 100. Note that Figure 2 illustrates a cross section cut along a plane that is perpendicular to the left-right direction of the tank truck 100 and that includes the axis of the cylindrical discharge pipe 6 (cylinder 7).

[0027] 2, a circular mounting hole 5b is formed in the equipment room 5, penetrating the roof 5a, and a cylindrical body 7 is fitted into the mounting hole 5b. The outer circumferential surface of the body 7 is welded to the edge of the mounting hole 5b, thereby fixing the body 7 to the roof 5a.

[0028] The inner diameter of the cylindrical body 7 is formed larger than the outer diameter of the discharge pipe 6, and the tip of the discharge pipe 6 is inserted from below into the inner peripheral side of the cylindrical body 7. In this inserted state, a gap is formed between the outer peripheral surface of the discharge pipe 6 and the inner peripheral surface of the cylindrical body 7.

[0029] A bracket 9 for fixing the discharge pipe 6 is attached to the lower end of the cylindrical body 7. The bracket 9 is an L-shaped metal fitting including a flat fixed plate 9a welded to the lower surface of the cylindrical body 7 and a fastening plate 9b bent downward from the inner edge of the fixed plate 9a (a portion located on the inner periphery of the cylindrical body 7). The discharge pipe 6 is fixed to the fastening plate 9b of the bracket 9 together with the container body 20, and details of this fixing structure will be described later.

[0030] Ventilation holes 7a are formed in the cylindrical body 7 at a location above the roof 5a (outside the equipment room 5). A plurality of ventilation holes 7a (four in this embodiment) are formed at equal intervals around the circumference of the cylindrical body 7, and the vaporized gas blown out from the discharge pipe 6 is discharged into the atmosphere through these ventilation holes 7a.

[0031] To prevent rainwater or foreign matter from entering through the ventilation hole 7a, a shade 8 is fixed to the cylindrical body 7 via a cover plate 10. The cover plate 10 is formed in a plate shape that covers the opening at the upper end of the cylindrical body 7, and the shade 8 is attached to the upper surface of the cover plate 10. The shade 8 includes a disk-shaped disc portion 8a and a cylindrical tube portion 8b that hangs down from the outer edge of the disk portion 8a. Although not shown, the cover plate 10 is formed in a rectangular shape when viewed from above, and the disk portions 8a of the shade 8 of this embodiment are fastened to the four corners of the cover plate 10 by bolts (not shown).

[0032] The diameter of the disk portion 8a (the inner diameter of the cylindrical portion 8b) is larger than the outer diameter of the cylindrical body 7, and the upper side of the air vent 7a is covered by the disk portion 8a. The lower end of the cylindrical portion 8b is located below the air vent 7a, and the lateral side of the air vent 7a is covered by the cylindrical portion 8b. This prevents rainwater and foreign matter from entering the inner periphery of the cylindrical body 7 (discharge pipe 6) through the air vent 7a. A gap is formed between the outer periphery of the cylindrical body 7 and the cylindrical portion 8b, so that vaporized gas can be discharged through this gap (air vent 7a) even when the shade 8 is attached to the cover plate 10.

[0033] On the other hand, if a gap is formed between the outer peripheral surface of the cylindrical body 7 and the cylindrical portion 8b, rainwater that has bounced off the roof 5a of the equipment room 5 may penetrate the inner peripheral side of the cylindrical body 7 through the gap and the ventilation holes 7a and adhere to the outer peripheral surface of the discharge pipe 6 and the inner peripheral surface of the cylindrical body 7. In order to prevent this rainwater from diffusing inside the equipment room 5, a container body 20 is attached to the discharge pipe 6. The configuration of this container body 20 will be described with reference to Figures 2 and 3. Figure 3 is a cross-sectional view of the container body 20 taken along line III-III in Figure 2.

[0034] 2 and 3, the container body 20 is attached so as to surround the entire outer periphery of the discharge pipe 6, and in this attached state is formed into a container shape with an open top. As a result, even if rainwater that has entered through the ventilation holes 7a drips down the outer periphery of the discharge pipe 6, the container body 20 can catch the rainwater. Furthermore, it is conceivable that condensation may occur on the outer periphery of the discharge pipe 6 due to some factor, but the container body 20 can also catch the moisture resulting from such condensation. Therefore, it is possible to prevent the rainwater and moisture resulting from condensation from diffusing into the equipment room 5.

[0035] The container body 20 comprises a first support 21 and a second support 22 (hereinafter collectively referred to as "supports 21, 22") which are fastened together to the fastening plate 9b of the bracket 9 by a bolt B1 and a nut N1, and a first receiving member 23 and a second receiving member 24 (hereinafter collectively referred to as "receiving members 23, 24") which are fixed to the supports 21, 22.

[0036] The first support 21 is an L-shaped metal fitting that includes a fastened plate 21a that is placed on the fastening plate 9b of the bracket 9, and a fixing plate 21b that is provided approximately perpendicular to the lower end of the fastened plate 21a. The second support 22 is a U-shaped (channel steel-like) metal fitting that includes a fastened plate 22a that is fastened together with the first support 21 (fastened plate 21a), and fixing plates 22b and upper plates 22c (see Figure 2) that are provided approximately perpendicular to the upper and lower ends of the fastened plate 22a.

[0037] The fastening plates 21a, 22a sandwiching the discharge pipe 6 and the bracket 9 (fastening plate 9b) are fastened together to the bolt B1 with a nut N1, whereby the supports 21, 22 are fixed on both sides of the discharge pipe 6 and the bracket 9.

[0038] A pair of nuts N2 aligned in a horizontal direction (the up and down direction in Figure 3; hereinafter simply referred to as the "horizontal direction") perpendicular to the fastening direction of the bolt B1 are welded to the fixed plate 21b of the first support 21, and a pair of nuts N3 aligned in a horizontal direction are also welded to the fixed plate 22b of the second support 22.

[0039] In this embodiment, a pair of nuts N2 are welded to both ends of the fixing plate 21b in the longitudinal direction (the vertical direction in FIG. 3 ) and to the outer sides of the fixing plate 21b in the width direction (positions farther from the fastened plate 21a than the center of the fixing plate 21b in the left-right direction in FIG. 3 ). Similarly, a pair of nuts N3 are welded to both ends of the fixing plate 22b in the longitudinal direction and to the outer sides of the fixing plate 22b in the width direction (positions farther from the fastened plate 22a than the center of the fixing plate 22b in the left-right direction in FIG. 3 ). The welding positions of the nuts N2 and N3 can be changed as long as they can secure the receiving members 23 and 24. However, taking into consideration the fastening work, it is preferable to weld the nuts N2 and N3 to the positions as in this embodiment. Although not shown, the fixing plates 21b and 22b of the supports 21 and 22 have through holes formed therein that connect to the female threaded holes of the nuts N2 and N3.

[0040] These nuts N2, N3 are for fastening the receiving members 23, 24 with bolts B2, B3. The first receiving member 23 includes a bottom plate 23a formed in a rectangular shape when viewed from above, and side plates 23b rising from three sides of the bottom plate 23a, and these plates 23a, 23b are integrally formed.

[0041] The bottom plate 23a of the first receiving member 23 is fastened to the fixing plate 21b of the support 21 with bolts B2 and nuts N2, whereby the first receiving member 23 is fixed (supported) to the support 21. A semicircular notch 23c (see FIGS. 3 and 5) is formed in a side end portion (the side on which the side plate 23b is not formed) of the bottom plate 23a of the first receiving member 23, and when the first receiving member 23 is fixed to the support 21, the discharge pipe 6 is fitted into the notch 23c.

[0042] A drainage hole 23d is formed in the bottom plate 23a of the first receiving member 23, and a semicircular notch 21c is formed in the side end (the long side on which the fastened plate 21a is not provided) of the fixing plate 21b of the first support 21 at a position corresponding to the drainage hole 23d.

[0043] A cylindrical drain pipe 23e (see FIG. 2) connected to the drain hole 23d is fixed to the underside of the bottom plate 23a. An internal thread is formed on the inner peripheral surface of the drain pipe 23e, and the drain pipe 23e is blocked by a bolt B4 fastened to this internal thread. By removing the bolt B4 from the drain pipe 23e, rainwater accumulated in the receiving members 23, 24 is drained through the drain hole 23d and the drain pipe 23e. Without such a drainage structure, there is a concern that rainwater will continue to accumulate in the container body 20, and as a result, the rainwater will overflow from the container body 20 and spread inside the equipment room 5.

[0044] In this embodiment, it is assumed that a portable container is used (rainwater is collected in the container) when draining rainwater from the container body 20 through the drain pipe 23e, but a configuration in which a conduit (hose or piping) for draining the rainwater outside the equipment room 5 is provided may also be used.

[0045] One example of such a configuration is one in which one end of a conduit is connected to the drain hole 23d (drain pipe 23e) and the other end of the conduit protrudes from a through-hole provided in the wall of the equipment room 5 to the outside of the wall of the equipment room 5 (or the other end of the conduit is connected so as to be flush with the outer surface of the wall of the equipment room 5). With this configuration, rainwater received by the receiving members 23, 24 is automatically drained to the outside of the equipment room 5 through the drain hole 23d (drain pipe 23e) and the conduit, eliminating the need to collect rainwater that has accumulated in the receiving members 23, 24. Furthermore, when the conduit is used to drain rainwater to the outside of the equipment room 5, the bolt B4 is not required.

[0046] The second receiving member 24 has the same configuration (shape) as the first receiving member 23, except that it does not have the drain hole 23d and the drain pipe 23e. Therefore, the second receiving member 24 has a bottom plate 24a and side plates 24b similar to those of the first receiving member 23, and the bottom plate 24a of the second receiving member 24 is fastened to the fixing plate 22b of the second support 22 with bolts B3 and nuts N3, whereby the second receiving member 24 is fixed (supported) to the second support 22. In this fixed state, the discharge pipe 6 is fitted into a semicircular notch 24c formed in the bottom plate 24a (see FIG. 3).

[0047] When each of the receiving members 23, 24 is fixed to the supports 21, 22 (hereinafter referred to as the "mounted state of the receiving members 23, 24"), the side ends (side surfaces) of the bottom plates 23a, 24a and the side ends of the side plates 23b, 24b are butted together (see Figure 3), and these bottom plates 23a, 24a and side plates 23b, 24b form a container shape that surrounds the outer surface of the discharge pipe 6.

[0048] The inner diameter of the container shape formed by the receiving members 23, 24 (the diameter of an imaginary circle that contacts the side plates 23b, 24b when viewed from above) is larger than the inner diameter of the cylindrical body 7, so that the receiving members 23, 24 can receive not only rainwater running down the outer circumferential surface of the discharge pipe 6, but also rainwater running down the inner circumferential surface of the cylindrical body 7. This makes it possible to more effectively prevent rainwater from diffusing into the equipment room 5.

[0049] In this way, when the purpose is to receive rainwater using a container formed around the discharge pipe 6, it is possible to form the receiving members 23, 24 integrally, for example, and insert the tip of the discharge pipe 6 into the insertion holes corresponding to the notches 23c, 24c (fit the integrally formed receiving members 23, 24 from the tip side of the discharge pipe 6). However, with such a configuration, it becomes difficult to later attach the receiving members 23, 24 to the discharge pipe 6 in a state where it is inserted into the cylindrical body 7 (assembled inside the equipment room 5).

[0050] In contrast, the container body 20 of this embodiment includes the first receiving member 23 and the second receiving member 24 that sandwiches the discharge pipe 6 between the first receiving member 23 and the second receiving member 24 to form the container shape, and therefore these receiving members 23, 24 can be attached from the lateral side of the discharge pipe 6. Therefore, the receiving members 23, 24 can be easily attached later to the discharge pipe 6 in a state where it is inserted into the cylindrical body 7.

[0051] The container body 20 is not provided on conventional tank trucks, but the bracket 9 is a member for fixing the discharge pipe 6 to the cylindrical body 7, and is also provided on existing tank trucks. In existing tank trucks, the discharge pipe 6 is fixed by a U-bolt or the like, using an insertion hole 9c (see FIG. 4) provided in the bracket 9.

[0052] In the container body 20 of this embodiment, the supports 21 and 22 are fastened and fixed by bolts B1 (first fastening members) inserted into insertion holes 9c (holes originally provided for fastening the discharge pipe 6) of the bracket 9, and the receiving members 23 and 24 are fastened and fixed to the supports 21 and 22 by bolts B2 and B3 (second fastening members). This allows the receiving members 23 and 24 (container body 20) to be attached using the bracket 9 provided on an existing tank truck. This eliminates the need to provide separate parts for attaching the receiving members 23 and 24. In other words, the bracket 9 can have the function of fixing the discharge pipe 6 to the cylindrical body 7 and the function of attaching the receiving members 23 and 24.

[0053] As described above, when the receiving members 23, 24 are attached, the side ends (side surfaces) of the bottom plates 23a, 24a and the side ends of the side plates 23b, 24b are butted against each other, and a sealant is applied (coated or filled) to at least one of the surfaces of the butted portions of the bottom plates 23a, 24a and the side plates 23b, 24b that are on the inside or outside of the container body 20. In addition, a sealant is also applied to the mating surfaces of the discharge pipe 6 and the notches 23c, 24c, and these sealants can prevent rainwater received in the receiving members 23, 24 from leaking from the mating surfaces of the discharge pipe 6 and the receiving members 23, 24.

[0054] In order to properly apply such a sealing material and prevent water leakage, it is preferable that there be no gaps between the mating surfaces of the discharge pipe 6 and the receiving members 23, 24 when the receiving members 23, 24 are attached (i.e., before the sealing material is applied). Furthermore, if a relative positional deviation occurs between the discharge pipe 6 and the receiving members 23, 24 (or between the receiving members 23, 24 themselves) due to vibrations while the tank truck 100 is traveling, the sealing material applied to their mating surfaces is likely to deteriorate. Therefore, it is preferable that the supports 21, 22 that support the receiving members 23, 24 and the discharge pipe 6 are firmly (stably) fixed to the bracket 9.

[0055] In contrast, in this embodiment, the discharge pipe 6, bracket 9, and supports 21, 22 are fastened together by bolts B1 arranged on both sides of the discharge pipe 6, so the discharge pipe 6 and the supports 21, 22 can be firmly (stably) fixed to the bracket 9. This makes it possible to suppress relative positional deviation between the discharge pipe 6 and the receiving members 23, 24 (or the receiving members 23, 24 themselves). Therefore, gaps are less likely to occur at the mating surfaces of the discharge pipe 6 and the receiving members 23, 24 (deterioration of the sealing material can be suppressed), so water leakage from those mating surfaces can be suppressed.

[0056] In this way, when the object is to attach the receiving members 23, 24 to the bracket 9 provided on an existing tank truck, it is also possible to employ a configuration in which the discharge pipe 6 and the support 221 are fastened together to the bracket 9 by a U-shaped bolt B5 and the receiving members 23, 24 are fixed to the support 221 (one component), as in a container body 220 of a second embodiment described later (see FIG. 6 ). However, in such a configuration, the fastening force of the bolt B5 acts only on the support 221 of the container body 220, and not on the receiving members 23, 24. In other words, since the fastening force of the bolt B5 does not act in the direction in which the receiving members 23, 24 sandwich the discharge pipe 6 (in the direction in which the receiving members 23, 24 fill the gap between the mating surfaces of the discharge pipe 6 and the receiving members 23, 24), gaps are likely to occur between the mating surfaces of the discharge pipe 6 and the receiving members 23, 24.

[0057] In contrast, in this embodiment, the first support 21 to which the first receiving member 23 is fixed and the second support 22 to which the second receiving member 24 is fixed are separate parts. The supports 21, 22 that sandwich the discharge pipe 6 and the bracket 9 are fastened together by the bolt B1, and therefore the fastening force of the bolt B1 can be applied in the direction in which the receiving members 23, 24 sandwich the discharge pipe 6 (in the direction in which the gap between the mating surfaces of the discharge pipe 6 and the receiving members 23, 24 is filled). This makes it difficult for gaps to occur in the mating surfaces of the discharge pipe 6 and the receiving members 23, 24 (deterioration of the sealing material can be suppressed), and water leakage from those mating surfaces can be suppressed.

[0058] In addition, the first support 21 comprises a fastening plate 21a (first fastening plate) that is placed on top of the bracket 9 and fastened by the bolt B1, and a fixing plate 21b (first fixing plate) that is arranged approximately perpendicular to the lower end of the fastening plate 21a and to which the first receiving member 23 is fixed, so that the rigidity of the first support 21 against bending in the fastening direction of the bolt B1 can be ensured by the fixing plate 21b.

[0059] Similarly, the second support 22 comprises a fastening plate 22a (second fastening plate) which sandwiches the discharge pipe 6 between itself and the fastening plate 21a and is fastened by a bolt B1, and a fixing plate 22b (second fixing plate) which is arranged approximately perpendicular to the lower end of the fastening plate 22a (second fastening plate) and to which the second receiving member 24 is fastened, so that the rigidity of the second support 22 against bending in the fastening direction of the bolt B1 can be ensured by the fixing plate 22b.

[0060] By ensuring the rigidity of the supports 21, 22 in the fastening direction of the bolt B1, the support members 21, 22 can firmly sandwich the discharge pipe 6 and the bracket 9. This makes it possible to suppress relative positional deviation between the discharge pipe 6 and the receiving members 23, 24, making it difficult for gaps to occur at the mating surfaces of the discharge pipe 6 and the receiving members 23, 24 (deterioration of the sealing material can be suppressed). This makes it possible to suppress water leakage at those mating surfaces.

[0061] To ensure the rigidity of the first support 21 against the fastening force of the bolt B1, it is possible, for example, to form an upper plate (flange) on the upper end of the first support 21, but in this embodiment, only the fixing plate 21b is formed on the first support 21. This is because the first support 21 is placed on an L-shaped bracket 9 including a fixed plate 9a and a fastening plate 9b, and bending of the first support 21 due to the fastening force of the bolt B1 can be restricted by the bracket 9. In other words, by forming only the fixing plate 21b on the first support 21 that is placed on the bracket 9 (omitting the upper plate), the parts cost of the first support 21 can be reduced while ensuring the rigidity of the first support 21 against the fastening force of the bolt B1.

[0062] On the other hand, since the second support 22 does not have any stiffening parts such as the bracket 9 superimposed thereon, an upper plate 22c (see FIG. 2) is provided at an approximately right angle on the upper end of the second support 22. This ensures the rigidity of the second support 22 against the fastening force of the bolt B1. Since the upper plate 22c comes into contact with (is superimposed on) the underside of the cylindrical body 7 when the receiving members 23, 24 are attached, the relative displacement in the vertical direction between the discharge pipe 6 and the cylindrical body 7 (relative displacement that increases the insertion depth of the discharge pipe 6 into the cylindrical body 7) caused by vibrations while the tank truck 100 is traveling, etc., can be regulated by the contact between the cylindrical body 7 and the upper plate 22c.

[0063] This makes it possible to suppress fatigue of the bracket 9 compared to when the relative displacement between the discharge pipe 6 and the cylindrical body 7 is restricted only by the bracket 9. Furthermore, by restricting the relative displacement between the discharge pipe 6 and the cylindrical body 7 by each of the bracket 9 and the second support 22, it is possible to suppress vertical displacement (vibration) of the receiving members 23, 24. Therefore, it is possible to suppress rainwater collected in the receiving members 23, 24 from scattering into the equipment room 5.

[0064] In addition, a rubber cushion 25 is adhered to the fastened plate 22a of the second support 22. The cushion 25 is disposed between the opposing pair of bolts B1, and the cushion 25 is compressed between the discharge pipe 6 and the fastened plate 22a by the fastening force of the bolts B1. This cushion 25 can suppress slippage between the discharge pipe 6 and the second support 22 (up and down displacement of the discharge pipe 6), and can also suppress damage to the discharge pipe 6 and the second support 22.

[0065] Here, rainwater adhering to the outer peripheral surface of the discharge pipe 6 or the inner peripheral surface of the cylindrical body 7 may be scattered around due to vibrations while the tank truck 100 is traveling, so it is preferable to arrange the receiving members 23, 24 as close as possible to the cylindrical body 7. Therefore, in this embodiment, the upper ends of the side plates 23b, 24b of the receiving members 23, 24 are positioned higher than the lower end of the cylindrical body 7. This allows the lower end portion of the cylindrical body 7 to be surrounded by the receiving members 23, 24 (side plates 23b, 24b). Therefore, even if rainwater adhering to the discharge pipe 6 or the cylindrical body 7 is scattered around, the scattered rainwater can be received by the receiving members 23, 24.

[0066] On the other hand, if the receiving members 23, 24 are arranged close to the cylindrical body 7, the space between the roof 5a of the equipment room 5 and the side plates 23b, 24b becomes narrow. Therefore, when fixing the receiving members 23, 24 to the supports 21, 22, it is difficult to insert tools or the like from above the receiving members 23, 24 (for example, to perform bolting or welding).

[0067] In contrast to this, in this embodiment, the receiving members 23, 24 can be attached to the supports 21, 22 by fastening bolts B2, B3 on the underside of the receiving members 23, 24. The method of attaching the receiving members 23, 24 (the method of attaching the container body 20 to the discharge pipe 6) will be described with reference to Figs. 4 and 5.

[0068] Fig. 4 is a perspective view showing the container body 20 in an exploded state. Fig. 5(a) is a front view of the first support member 21, and Fig. 5(b) is a side view of the first support member 21 as viewed in the direction of arrow Vb in Fig. 5(a). Fig. 5(c) is a front view of the second support member 22, and Fig. 5(d) is a side view of the second support member 22 as viewed in the direction of arrow Vd in Fig. 5(c). Fig. 5(e) is a top view of the first receiving member 23, and Fig. 5(f) is a front view of the first receiving member 23 as viewed in the direction of arrow Vf in Fig. 5(e).

[0069] 4 and 5, a pair of insertion holes 21d aligned horizontally is formed in the fastening plate 21a of the first support 21, and this pair of insertion holes 21d is formed at positions corresponding to insertion holes 9c (see FIG. 4) formed in the fastening plate 9b of the bracket 9. A pair of insertion holes 22d aligned horizontally (on both sides of the cushion 25) is formed in the fastening plate 22a of the second support 22, and the distance between this pair of insertion holes 22d is the same as the distance between the insertion holes 21d of the first support 21.

[0070] A pair of insertion holes 23f aligned horizontally is formed in the bottom plate 23a of the first receiving member 23 (see FIG. 5(e)), and this pair of insertion holes 23f is formed at positions corresponding to the nuts N2 provided on the fixing plate 21b of the first support 21. A pair of insertion holes 24d aligned horizontally is also formed in the bottom plate 24a of the second receiving member 24, and this pair of insertion holes 24d is formed at positions corresponding to the nuts N3 provided on the fixing plate 22b of the second support 22.

[0071] When attaching the container body 20 to the discharge pipe 6 and the bracket 9, first, the fastening plate 21a of the first support 21 is placed on the fastening plate 9b of the bracket 9, and then the bolt B1 passed through the insertion hole 22d of the second support 22 is inserted into the insertion holes 9c and 21d and the nut N1 is fastened. As a result, the discharge pipe 6, bracket 9, and supports 21 and 22 are fastened together by the bolt B1 and the nut N1 (see FIG. 2). At this time, the fastening plate 21a of the first support 21 and the fastening plate 22a of the second support 22 are made to be approximately parallel.

[0072] Next, bolt B2 inserted from below into insertion hole 23f (see FIG. 5) of first receiving member 23 is fastened to nut N2 of first support 21, and similarly, bolt B3 inserted from below into insertion hole 24d of second receiving member 24 is fastened to nut N3 of second support 22. This fixes receiving members 23, 24 to supports 21, 22.

[0073] In this manner, in this embodiment, the bolts B2, B3 can be fastened to the nuts N2, N3 of the supports 21, 22 on the undersides of the receiving members 23, 24. Therefore, even when the receiving members 23, 24 are disposed close to the cylindrical body 7 (see FIG. 2), the receiving members 23, 24 can be easily attached to the supports 21, 22.

[0074] Here, the portion of the discharge pipe 6 that is located below the container body 20 (receiving members 23, 24) is bent in the width direction of the tank truck 100 (the direction perpendicular to the paper surface in the cross-sectional view of FIG. 2). Since manufacturing errors occur in the curvature of the bent portion of this discharge pipe 6, the relative positions of the bracket 9 and the discharge pipe 6 are likely to shift in the width direction (horizontal direction) of the tank truck 100.

[0075] In contrast to this, in the present embodiment, the insertion hole 9c of the bracket 9 (see FIG. 4) and the insertion holes 23f, 24d of the receiving members 23, 24 (see FIG. 5 for the insertion hole 23f) are elongated holes extending in the vehicle width direction of the tank truck 100. As a result, the fixing positions of the supports 21, 22 to the bracket 9 and the fixing positions of the receiving members 23, 24 to the supports 21, 22 can be adjusted along the insertion holes 9c, 23f, 24d. Therefore, even if a deviation occurs in the relative position of the discharge pipe 6 with respect to the bracket 9, the discharge pipe 6 and the supports 21, 22 can be fixed to the bracket 9, and the discharge pipe 6 can be reliably fitted into the notches 23c, 24c of the receiving members 23, 24 (see FIG. 5 for the notch 23c).

[0076] Next, a container body 220 of a second embodiment will be described with reference to Fig. 6. In the first embodiment, the case where the discharge pipe 6 and the bracket 9 are sandwiched between the supports 21 and 22 has been described, but in the second embodiment, the case where the discharge pipe 6 and the bracket 9 are sandwiched between the support 221 and the U-shaped bolt B5 will be described. Note that the same parts as in the first embodiment described above are given the same reference numerals, and their description will be omitted. Fig. 6 is a perspective view showing an exploded state of the container body 220 of the second embodiment.

[0077] 6, the container body 220 of the second embodiment includes a support 221 that sandwiches the discharge pipe 6 and the bracket 9, and a U-shaped bolt B5. The support 221 has the same configuration as the first support 21 of the first embodiment (see FIG. 5), except that the dimension of the fastened plate 21a in the horizontal direction is shortened and a pair of fixing plates 221e are integrally formed on both ends of the fixing plate 21b in the horizontal direction.

[0078] When fixing the support 221 to the bracket 9, the fastened plate 21a is placed on the fastening plate 9b of the bracket 9, and the U-shaped bolt B5 that sandwiches the discharge pipe 6 is inserted into the insertion holes 9c and 21d, and the nut N1 is fastened. As a result, the discharge pipe 6, bracket 9, and support 221 are fastened together by the bolt B5 and the nut N1.

[0079] The first receiving member 23 is fixed to the support 221 by fastening the bolt B2 and the nut N2, as in the first embodiment. On the other hand, the second receiving member 24 is fixed to the fixing plate 221e of the support 221.

[0080] The fixing plates 221e are formed in a flat plate shape extending from the fixing plate 21b toward the second receiving member 24, and a nut N3 is welded to the upper surface of the tip side of each of the pair of fixing plates 221e. A through hole (not shown) connected to the female thread hole of the nut N3 is formed in the fixing plate 221e, and the second receiving member 24 is fixed to the support 221 by fastening a bolt B3 inserted from below into the insertion hole 24d of the second receiving member 24 to the nut N3.

[0081] In this fixed state, similar to the first embodiment, the bottom plates 23a, 24a and side plates 23b, 24b of the receiving members 23, 24 that sandwich the discharge pipe 6 form a container shape that surrounds the outer circumferential surface of the discharge pipe 6. As a result, even if rainwater drips down the outer circumferential surface of the discharge pipe 6, the receiving members 23, 24 (container body 220) can receive the rainwater. This can prevent the rainwater from diffusing into the equipment room 5 (see FIG. 2). Furthermore, since the receiving members 23, 24 can be attached around the discharge pipe 6 using a single support 221, the number of parts of the container body 220 can be reduced.

[0082] Also in this embodiment, there is provided a first receiving member 23 and a second receiving member 24 that forms a container shape by sandwiching the discharge pipe 6 between the first receiving member 23 and the second receiving member 24. This allows the receiving members 23, 24 to be attached from the lateral side of the discharge pipe 6.

[0083] In addition, the support 221 (support) is fastened to the bracket 9 by bolt B5 (first fastening member), and the receiving members 23, 24 are fixed to the support 221 by bolts B2, B3 (second fastening members), so that the receiving members 23, 24 can be attached around the discharge pipe 6 using the bracket 9 provided on an existing tank truck.

[0084] Furthermore, the U-shaped bolts B5 fasten the support 221 to the bracket 9 on both sides of the discharge pipe 6, so that the discharge pipe 6 and the support 221 can be firmly (stably) fixed to the bracket 9. This makes it possible to suppress relative positional deviation between the discharge pipe 6 and the receiving members 23, 24 (or between the receiving members 23, 24).

[0085] The present invention has been described above based on the above embodiment, but the present invention is not limited to the above form in any way, and it can be easily inferred that various modifications and improvements are possible within the scope that does not deviate from the spirit of the present invention.

[0086] In the above embodiments, the case where the container body 20, 220 is attached to the discharge pipe 6 of the tank truck 100 has been described, but this is not necessarily limited to this. For example, the container body 20, 220 may be attached to other vehicles such as a tank trailer or a tank semi-trailer, or the container body 20, 220 may be attached to a pipe other than the discharge pipe 6 as long as it is a pipe that protrudes from the roof 5a of the equipment room 5 (inserted into the inner peripheral side of the cylindrical body 7).

[0087] In the above-described embodiments, the container shape is formed by the receiving members 23, 24 (consisting of two parts) that sandwich the discharge pipe 6, but this is not necessarily limited to this. For example, a configuration is also possible in which the receiving members 23, 24 are integrally formed, the tip of the discharge pipe 6 is inserted through an insertion hole corresponding to the notches 23c, 24c, and the receiving members 23, 24 are fixed to the discharge pipe 6 by welding or the like. In such a configuration, the receiving members 23, 24 may be attached in advance to the discharge pipe 6 before it is assembled into the equipment chamber 5, or the discharge pipe 6 may be removed from the equipment chamber 5 and the receiving members 23, 24 may be attached thereto.

[0088] Alternatively, for example, the receiving members 23, 24 may be integrally formed using hard rubber to form a rubber container, and a slit may be provided that leads to the insertion hole corresponding to the notches 23c, 24c (rather than dividing the container shape as in the receiving members 23, 24, a crack may be provided in part of the rubber container). With such a configuration, the slit portion may be widened to elastically deform the container, and the discharge pipe 6 may be fitted into the insertion hole, thereby attaching the container to the outer circumferential surface of the discharge pipe 6. After this attachment, the container may be joined to the discharge pipe 6 with an adhesive or the like.

[0089] In the above-described embodiments, a fastening structure using the supports 21, 22, 221, bolts B1 to B3, B5, and nuts N1 to N3 has been described as an example of a means for holding the receiving members 23, 24 in a state where they sandwich the discharge pipe 6, but this is not necessarily limited to this. For example, another example of such a holding means is a configuration in which the fastening structure as described above is omitted and the receiving members 23, 24 that sandwich the discharge pipe 6 (the mating surfaces of the discharge pipe 6 and the receiving members 23, 24) are joined together by adhesive bonding, welding, or the like.

[0090] As another example, instead of joining the mating surfaces of the receiving members 23, 24, splice plates attached to the side plates 23b, 24b of the receiving members 23, 24 may be bolted or welded to the side plates 23b, 24b.

[0091] Furthermore, instead of holding the receiving members 23, 24 that clamp the discharge pipe 6 with the supports 21, 22, 221 (brackets 9), for example, the supports 21, 22, 221 may be omitted, and a support member (for example, an L-shaped metal fitting) may be fixed to the outer surface of the discharge pipe 6 to support the receiving members 23, 24 from below, which are connected by welding or the like as described above.

[0092] In other words, the method of connecting the receiving members 23, 24 that sandwich the discharge pipe 6 and the method of holding the connected receiving members 23, 24 on the outer peripheral surface of the discharge pipe 6 are not limited to the above forms and can be changed as appropriate.

[0093] In the above-described embodiments, the cases where the receiving members 23, 24 (supports 21, 22, 221) are attached using the bracket 9 provided on the existing tank truck 100 (welded to the cylindrical body 7) have been described, but this is not necessarily limited to this. For example, a configuration may be adopted in which the bracket 9 is omitted and the supports 21, 22, 221 are welded to the cylindrical body 7. In this case, an upper plate (flange) may be provided at the upper end portion of the fastened plate 21a of the supports 21, 221, and the upper plate may be welded to the lower surface of the cylindrical body 7, or the upper plate 22c of the second support 22 may be welded to the lower surface of the cylindrical body 7.

[0094] In the above-described embodiments, the discharge pipe 6, the bracket 9, and the supports 21, 22, 221 are fastened together by the bolts B1, B5 arranged on both sides of the discharge pipe 6. However, this is not necessarily limited to this. For example, the discharge pipe 6 may be welded to the fastening plate 9b of the bracket 9. In this configuration, the supports 21, 22, 221 do not need to have the function of fixing the discharge pipe 6 to the bracket 9 (sandwiching the discharge pipe 6 and the bracket 9). Therefore, for example, the supports 21, 22, 221 may be divided into a portion fastened by one of a pair of bolts B1 and a portion fastened by the other bolt B1 (or one portion may be omitted). In other words, the supports 21, 22, 221 do not need to be fastened together with the discharge pipe 6 and the bracket 9.

[0095] In the above embodiments, the second receiving member 24 has the same configuration (shape) as the first receiving member 23, except that it does not include the drain hole 23d and the drain pipe 23e. However, this is not necessarily limited to this. For example, the drain hole 23d and the drain pipe 23e may be provided in the second receiving member 24, or the drain hole 23d and the drain pipe 23e of the first receiving member 23 may be omitted. In either configuration, the receiving members 23, 24 have the same shape, which reduces the number of types of parts of the container body 20, 220. This reduces the manufacturing cost of the container body 20, 220 and prevents incorrect assembly of the receiving members 23, 24.

[0096] In the above-described embodiments, the inner diameter of the container shape formed by the receiving members 23, 24 (the diameter of an imaginary circle tangent to the side plates 23b, 24b in a top view) is larger than the inner diameter of the cylindrical body 7. However, this is not necessarily limited to this. For example, the inner diameter of the receiving members 23, 24 (container shape) may be smaller than the inner diameter of the cylindrical body 7, or the inner diameters may be the same. However, if the inner diameter of the receiving members 23, 24 is smaller than the inner diameter of the cylindrical body 7, there is a concern that rainwater that has trickled down the inner circumferential surface of the cylindrical interior 7 may be dispersed into the equipment room 5 without being collected by the receiving members 23, 24, depending on the situation. Therefore, it is desirable to make the inner diameter of the receiving members 23, 24 larger than the inner diameter (or outer diameter) of the cylindrical body 7.

[0097] In the above embodiments, the description of the arrangement of the drainage holes 23d (drainage pipes 23e) has been omitted, but for example, if the bottom plates 23a, 24a are inclined relative to the horizontal direction when the receiving members 23, 24 are attached, it is preferable to provide the drainage holes 23d (drainage pipes 23e) on the lower end sides of the inclined bottom plates 23a, 24a. This makes it easier for rainwater received in the receiving members 23, 24 to be drained through the drainage holes 23d.

[0098] In the above embodiments, the container shape of the receiving members 23, 24 is rectangular when viewed from above, but this is not necessarily limited to this. The container shape of the receiving members 23, 24 when viewed from above may be circular or another polygonal shape.

[0099] In the above embodiments, the bottom plates 23a, 24a and the side plates 23b, 24b of the receiving members 23, 24 are simply butted together, and a sealant is applied to their mating surfaces. However, this is not necessarily limited to this. For example, a groove (groove extending along the mating surface) may be formed in one or both of the mating surfaces of the receiving members 23, 24, and a sealant rubber may be sandwiched in the groove. This makes it less likely for water to leak from the mating surfaces of the receiving members 23, 24.

[0100] Alternatively, the groove may be formed on one of the mating surfaces of the receiving members 23, 24, and a protrusion (a protrusion extending along the mating surface) that fits into the groove may be formed on the other mating surface. This configuration also makes it difficult for water to leak from the mating surfaces of the receiving members 23, 24.

[0101] Furthermore, the above-mentioned groove may be formed in the mating surface of the notch 21c with the discharge pipe 6, and a seal rubber may be sandwiched in the groove. This makes it difficult for water to leak from the mating surfaces of the discharge pipe 6 and the receiving members 23, 24.

[0102] In each of the above embodiments, the insertion holes 23f, 24d are described as elongated holes extending in the vehicle width direction, but, for example, either one or both of the insertion holes 23f, 24d may be elongated holes extending in the vehicle longitudinal direction (or in a direction inclined relative to that direction).

[0103] In the first embodiment, the fixing plates 21b, 22b are provided at approximately right angles to the lower ends of the fastened plates 21a, 22a of the supports 21, 22, and the upper plate 22c is provided at approximately right angles to the upper ends of the fastened plates 22a. However, this is not necessarily limited to this. For example, the supports 21, 22 (fastened plates 21a, 22a) without the fixing plates 21b, 22b may be welded to the bottom plates 23a, 24a of the receiving members 23, 24. Alternatively, the upper plate may be provided at approximately right angles to the upper ends of the fastened plates 21a, or the upper plate 22c of the fastened plates 22a may be omitted. In other words, the shapes of the supports 21, 22 and the receiving members 23, 24 can be changed as needed as long as the supports 21, 22 can be fixed to the bracket 9.

[0104] In the first embodiment described above, the first receiving member 23 is fixed to the first support 21, and the second receiving member 24 is fixed to the second support 22 (i.e., the first receiving member 23 is fastened to a pair of nuts N2, and the second receiving member 24 is fastened to a pair of nuts N3), but this is not necessarily limited to this. For example, the first receiving member 23 may be fastened to nuts N2 and N3, and the second receiving member 24 may be fastened to nuts N2 and N3, respectively, so that the receiving members 23 and 24 are fixed so as to span the supports 21 and 22. Similarly, in the second embodiment, the first receiving member 23 (second receiving member 24) may be fastened to nuts N2 and N3. [Explanation of symbols]
