[0043] The utility model provides a tank box, which is used to load liquid media. In actual use, it can be applied to loading liquid media such as sulfur / ammonium nitrate and asphalt in a high temperature environment. In the tank box, when it is necessary to open the manhole 11 on the tank body 1, the sealing plate 4 on the cover body 2 is removed from the manhole 11. Under the action of the reset force of the elastic member 51, the sealing plate 4 is moved close to the cover body 2 and keeps the manhole 11 open. The operator controls the cover body 2 to rotate relative to the tank body 1 through the first adjusting device 3, so that the cover body 2 and the sealing plate 4 are turned open on the manhole 11 together; when it is necessary to close the manhole 11, the cover body 2 is controlled to rotate back to the position corresponding to the manhole 11 through the first adjusting device 3, so that the sealing plate 4 is aligned with the manhole 11, and then the second adjusting device 6 overcomes the reset force of the elastic member 51 and can push the sealing plate 4 away from the cover body 2 until the sealing plate 4 is sealed on the manhole 11. The tank container of the present application can realize the opening or closing of the manhole 11 on the tank body 1 from a long distance, thereby preventing the operator from being harmed by the high-temperature steam and residual toxic gas in the tank during the process of opening the manhole 11, thereby improving application safety and reducing safety hazards.

[0044] Figure 1 A schematic diagram of a tank container from a top view is shown. Figure 2 It shows a schematic diagram of the cover body 2 closing the manhole 11 of the tank body 1 from a top view. Figure 3 It shows a schematic diagram of the cover body 2 opening the manhole 11 of the tank body 1 from a top view.

[0045] Reference Figures 1 to 3 A manhole 11 is provided on the top of the tank body 1, and a rotating shaft 12 is provided on the tank body 1. One side of the cover body 2 is rotatably connected to the tank body 1 through the rotating shaft 12. The cover body 2 is connected to the first adjusting device 3, so that the cover body 2 can reciprocate under the drive of the first adjusting device 3, and then Figure 2 The cover 2 shown in FIG. 1 is rotated to a position corresponding to the upper and lower positions of the manhole 11, or as shown in FIG. Figure 3 The cover body 2 is shown rotated to a position where it is offset from the manhole 11 in the vertical direction.

[0046] In this embodiment, the cover 2 rotates in a planar direction, i.e., the axial direction of the cover 2 is parallel to the rotation axis of the cover 2. Moreover, one side of the cover 2 is rotatably connected to the rotation shaft 12, which can increase the rotation range of the cover 2 and facilitate the opening and closing of the cover 2 to the manhole 11.

[0047] Furthermore, the cover 2 is provided with a connecting bracket 21 having a first rotating end 211, a second rotating end 212, and an adjustment end 213. The first rotating end 211 is rotatably connected to the tank body 1, and the second rotating end 212 is rotatably connected to the cover 2. The adjustment end 213 is located between the first rotating end 211 and the second rotating end 212, and is located on the side of the rotating shaft 12 facing away from the center of the cover 2. The first adjustment device 3 is connected to the adjustment end 213, and the first adjustment device 3 pushes and pulls the connecting bracket 21 back and forth to achieve rotation of the cover 2 relative to the tank body 1.

[0048] Specifically, the connecting bracket 21 includes a first rod 214 and a second rod 215, which are connected to form a V-shaped bracket structure. The location where the first rod 214 and the second rod 215 connect serves as the adjustment end 213. The end of the first rod 214 away from the second rod 215 is rotatably connected to the cover 2, and the end of the second rod 215 away from the first rod 214 is rotatably connected to the tank body 1. The design of the connecting bracket 21 facilitates the application of force by the first adjustment device 3, so that the cover 2 can rotate smoothly as the first adjustment device 3 pulls the connecting bracket 21. The first rod 214 and the second rod 215 can be fixedly connected by bolts or welding.

[0049] In addition, the cover 2 may also be integrally formed with a connection block on the outer circumference for connection of the first adjustment device 3. In other embodiments, the first adjustment device 3 may also be directly connected to the side of the cover 2, and the cover 2 can be rotated relative to the tank body 1 by pushing and pulling the cover 2.

[0050] Furthermore, the first adjustment device 3 includes a flexible cord and a sleeve 31. The sleeve 31 is mounted on the tank body 1, and a slideway is formed axially through the interior of the sleeve 31. The flexible cord passes through the slideway, and one axial end of the cord is synchronously connected to the cover body 2. The flexible cord is configured so that by pulling the other axial end of the cord, the cord can be pulled axially along the slideway within the sleeve 31, thereby driving the cover body 2 to rotate in a plane relative to the tank body 1.

[0051] Specifically, the kit 31 is pre-set on the tank body 1, and the extension direction of the slide formed in the kit 31 is the regular flexible rope travel track. Then, the flexible rope is inserted into the slide so that one axial end of the flexible rope is synchronously connected to the cover body 2. The operator can pull the other axial end of the flexible rope back and forth so that the flexible rope can slide in the predetermined slide extension direction, thereby accurately driving the cover body 2 to rotate back and forth. The kit 31 can extend in a straight line, be bent into multiple sections of broken lines, or extend in an arc. The specific layout of the kit 31 can be confirmed according to the on-site installation position. Preferably, the end of the kit 31 away from the cover body 2 can be led to the lower side of the tank body 1, which is convenient for the operator to operate the flexible rope. It should be noted that the size of the slide in the kit 31 matches the outer circumference of the flexible rope to prevent the flexible rope from twisting in the slide and to facilitate the control of the advance and retreat size of the flexible rope along the slide, thereby accurately controlling the rotation amplitude of the cover body 2.

[0052] The present embodiment drives the cover body 2 to open the manhole 11 when the flexible shaft rope is retracted, and drives the cover body 2 to cover the manhole 11 when the flexible shaft rope is released. In another embodiment, it can also be adjusted to drive the cover body 2 to cover the manhole 11 when the flexible shaft rope is retracted, and drive the cover body 2 to open the manhole 11 when the flexible shaft rope is released. Among them, the flexible shaft rope can be retracted and released by manually pulling the flexible shaft rope or manually controlling the retraction and release of the flexible shaft rope, which is convenient for the operator to adjust the pulling force and avoids the medium solidifying between the manhole 11 and the cover body 2 when the electric control element is used for control, causing difficulty in opening and closing and causing damage to the electric control element. The specific retraction and release scheme of the manually controlled flexible shaft rope can be as follows: a clamp can be provided on the flexible shaft rope, and the clamp is connected to the cover body 31 along the axial direction of the sleeve 31, or the clamp is slidably connected to the tank body 1, and the operator toggles the clamp back and forth so that the flexible shaft rope can slide in the slideway, thereby driving the cover body 2 to rotate. In some other embodiments, the end of the flexible shaft rope away from the cover body 2 can also be retracted and extended by a hand wheel or other means.

[0053] In this embodiment, the cover 2 is rotated along a plane by pulling the flexible rope. In another embodiment, the cover 2 can also be adjusted in a flip-up manner relative to the manhole 11 to open and close the manhole 11. In actual applications, a drive element such as a cylinder can also be used to achieve horizontal rotation or flip adjustment of the cover 2.

[0054] In some embodiments, reference Figure 4 The first adjustment device 3 also includes a flexible shaft retractable structure 34, located at the bottom of the tank body 1 for easy operator control. The axial end of the flexible shaft cord, away from the cover body 2, passes through the sleeve 31 and is synchronously connected to the flexible shaft retractable structure 34. The flexible shaft retractable structure 34 is configured to pull the flexible shaft cord relative to the sleeve 31. By controlling the flexible shaft retractable structure 34, the operator can control the sliding retraction and release of the flexible shaft cord relative to the sleeve 31.

[0055] Furthermore, the flexible shaft retractable structure 34 is a linkage mechanism. Specifically, the flexible shaft retractable structure 34 includes a third rod and a swing arm for operator rotational manipulation. The swing arm is rotatably connected to the tank body 1. The flexible shaft cord is synchronously connected to one end of the third rod, which is fixed to the swing arm. The operator rotates the swing arm to cause the third rod to swing, thereby pulling or releasing the flexible shaft cord relative to the sleeve 31. An operating box is provided on the tank body 1. The flexible shaft retractable structure 34 is disposed within the operating box, and the swing arm extends outside the operating box to facilitate operator operation.

[0056] Combine Figure 2 and Figure 3 Furthermore, the kit 31 includes a positioning sleeve 311 and a movable sleeve rod 312 that are connected in sequence. The positioning sleeve 311 is provided on the tank body 1. Specifically, the operator can arrange the extension direction of the positioning sleeve 311 according to the layout of the manhole 11 and a position that is convenient for operation. In this embodiment, the positioning sleeve 311 is bent into multiple sections and extended, and the positioning sleeve 311 can be fixed to the tank body 1 by a plurality of pipe buckles 314 that are arranged at intervals and have grooves. The positioning sleeve 311 can be made of plastic material, and the positioning sleeve 311 can be a whole soft pipe, or it can be spliced ​​together by multiple sections of pipes.

[0057] The movable sleeve rod 312 is rotatably connected to the axial end of the positioning sleeve 311 close to the cover body 2, so that the movable sleeve rod 312 can swing relative to the positioning sleeve 311. At least a portion of the slideway is constructed between the interior of the positioning sleeve 311 and the interior of the movable sleeve rod 312, and the axial end of the flexible shaft rope penetrates into the interior of the movable sleeve rod 312. The interior of the positioning sleeve 311 is axially penetrated to form a first channel, and the interior of the movable sleeve rod 312 is penetrated to form a second channel. The ends of the first channel and the second channel are interconnected, so that the flexible shaft rope can penetrate into the first channel and the second channel in sequence. When the flexible shaft rope synchronously pulls the cover body 2 to rotate back and forth, the movable sleeve rod 312 can swing and adjust with the rotation position of the cover body 2, thereby guiding the flexible shaft rope.

[0058] The first adjustment device 3 further includes a first pull rod 32, which is connected between the cover 2 and one end of the flexible shaft rope that passes through the movable sleeve rod 312. The first pull rod 32 can pass through the movable sleeve rod 312 and move back and forth along the extension direction of the slideway. In other words, the first pull rod 32 can pass through the second channel and move axially along the second channel.

[0059] Specifically, the first pull rod 32 is connected between the cover body 2 and the flexible shaft rope, so that the flexible shaft rope is synchronously connected to the cover body 2, and the shape of the first pull rod 32 is fixed. The first pull rod 32 can slide axially along the inner side of the movable sleeve rod 312, and the movable sleeve rod 312 can guide the first pull rod 32 to ensure that the first pull rod 32 can move into place, thereby accurately controlling the rotation angle and amplitude of the cover body 2. In specific use, when the flexible shaft rope is pulled away from the other axial end of the first pull rod 32, the first pull rod 32 can slide along the partial slideway enclosed by the movable sleeve rod 312 with the flexible shaft rope, thereby pulling the cover body 2 to rotate to the position corresponding to the manhole 11. When the flexible shaft rope is released away from the other axial end of the first pull rod 32, the first pull rod 32 can slide out along the movable sleeve rod 312, thereby pushing the cover body 2 to rotate to a position staggered with the manhole 11. The circumferential dimension of the first pull rod 32 matches the inner circumferential dimension of the movable sleeve rod 312 , so as to ensure that the first pull rod 32 slides back and forth along the slideway inside the movable sleeve rod 312 .

[0060] In this embodiment, one axial end of the first pull rod 32 is connected to the adjustment end 213 of the connecting bracket 21, and the other axial end of the first pull rod 32 is connected to the flexible shaft rope, thereby achieving synchronous connection of the flexible shaft rope to the adjustment end 213. In other embodiments, one axial end of the flexible shaft rope can also be directly connected to the cover body 2. In addition, a reset structure can be provided between the cover body 2 and the tank body 1. After the flexible shaft rope pulls the cover body 2 to rotate, when the flexible shaft rope is released, the reset structure can drive the cover body 2 to reset.

[0061] like Figures 1 to 3 As shown, a sleeve rod bracket 33 is provided on the tank body 1, one end of the positioning sleeve 311 is positioned on the sleeve rod bracket 33 by a bolt, one end of the movable sleeve rod 312 is positioned on the sleeve rod bracket 33 by a universal joint 313, and the interior of the movable sleeve rod 312 is connected to the interior of the positioning sleeve 311, so that the movable sleeve rod 312 can rotate relative to the positioning sleeve 311.

[0062] Furthermore, the first adjustment device 3 also includes a second pull rod, which is connected between the soft shaft retracting structure 34 and the end of the soft shaft rope away from the cover body 2. The second pull rod can penetrate into the kit 31 and move back and forth along the extension direction of the slide.

[0063] Specifically, the flexible shaft rope is connected to the flexible shaft retracting structure 34 through a second pull rod. Under the pulling action of the flexible shaft retracting structure 34, the second pull rod can be inserted into the kit 31 and can move axially along the slideway on the kit 31, thereby guiding the second pull rod and ensuring that the cover body 2 is rotated into place.

[0064] In this embodiment, one axial end of the second pull rod is connected to the soft shaft rope, and the other axial end of the second pull rod is connected to the third rod of the soft shaft retracting structure 34. In addition, the kit 31 includes a movable sleeve rod 312, a positioning sleeve 311, and a second movable sleeve rod 312 connected in sequence. The interior of the movable sleeve rod 312, the interior of the positioning sleeve 311, and the interior of the second movable sleeve rod 312 are connected in sequence and jointly construct a slideway. One axial end of the second movable sleeve rod 312 is rotatably connected to one end of the positioning sleeve 311, so that the second movable sleeve rod 312 can swing relative to the positioning sleeve 311. The second pull rod can be inserted into the second movable sleeve rod 312 and slide along the internal axial direction of the second movable sleeve rod 312. The second movable sleeve rod 312 serves as a guide for the second pull rod. The second movable sleeve rod 312 and the second pull rod are both located in the operating box.

[0065] Reference Figure 4 and Figure 5 , Figure 4 A schematic front view of the tank container provided for this application; Figure 5 This is a partial enlarged view of the cover plate and the sealing plate 4 of the tank container of this application.

[0066] Combine Figure 4 and Figure 5 Furthermore, the tank container further includes a sealing plate 4, which is disposed on the cover 2 and is configured to move with the cover 2 to a position opposite the manhole 11, or to a position offset from the manhole 11. Furthermore, the sealing plate 4 is movable relative to the cover 2, such that the sealing plate 4 can move away from the cover 2 to seal the manhole 11, or move toward the cover 2 to open the manhole 11. Specifically, the sealing plate 4 can be extended or retracted relative to the cover 2 to avoid interfering with the rotation of the cover 2, making it easier for an operator to remotely control the rotation of the cover 2 and thereby open and close the manhole 11.

[0067] like Figure 5 As shown, the sealing plate 4 is arranged below the cover body 2, and the sealing plate 4 can be slidably connected to the cover body 2 in the up and down directions, thereby sealing or opening the manhole 11, improving the activity stability of the sealing plate 4, and reducing the shaking of the sealing plate 4.

[0068] Furthermore, the top surface of the sealing plate 4 is provided with at least one connecting rod 41, which extends upward and penetrates the cover body 2. The sealing plate 4 is slidably connected to the cover body 2 via the connecting rod 41, thereby improving the stability of the sealing plate 4. In this embodiment, multiple connecting rods 41 are spaced apart on the top surface of the sealing plate 4, further improving the stability of the sealing plate 4. Alternatively, the sealing plate 4 can be slidably connected to the cover body 2 via a sliding groove and slider structure.

[0069] Furthermore, the tank container further includes a reset device 5 comprising an elastic member 51 connected between the cover 2 and the sealing plate 4. The elastic member 51 is configured to provide a reset force for the sealing plate 4 to move closer to the cover 2. The reset force of the elastic member 51 causes the sealing plate 4 to have an upward reset tendency. Consequently, when the second adjustment device 6 releases the downward push on the sealing plate 4, the sealing plate 4 can naturally move upward, thereby automatically releasing the seal on the manhole 11 and preventing the sealing plate 4 from interfering with the rotation of the cover 2.

[0070] Furthermore, the elastic member 51 is a compression spring, which is sleeved on the connecting rod 41. The connecting rod 41 serves as a guide for the compression spring, improving the stability of the compression spring's entire deformation stroke. The connecting rod 41 extends upward through the cover 2, and a stopper 411 is provided at the end of the connecting rod 41 facing away from the sealing plate 4. One axial end of the compression spring abuts against the stopper 411, while the other axial end of the compression spring abuts against the cover 2.

[0071] Specifically, the bottom end of the compression spring abuts against the cover 2, and the top end of the compression spring abuts against the limit block 411. This creates an upward reset force on the limit block 411, thereby causing the limit block 411, the connecting rod 41, and the sealing plate 4 to move upward synchronously. In this embodiment, the limit block 411, the connecting rod 41, and the sealing plate 4 are synchronously connected. The connecting rod 41 can be welded to the sealing plate 4, and the limit block 411 can be threaded onto the connecting rod 41 using a nut. The elastic member 51 is a compression spring with a large load capacity, allowing the elastic member 51 to store a greater reset force and saving design space.

[0072] In some other embodiments, the elastic member 51 may also be a tension spring, the upper end of the tension spring abuts against the cover body 2, and the lower end abuts against the sealing plate 4. The tension spring has a reset force to pull the sealing plate 4 upward.

[0073] Furthermore, the tank container further includes a second adjustment device 6. In some embodiments, the second adjustment device 6 includes an airbag, which is disposed between the cover 2 and the sealing plate 4. The airbag is configured to inflate and expand to move the sealing plate 4 away from the cover 2, or to deflate and contract to allow the elastic member 51 to drive the sealing plate 4 toward the cover 2. Specifically, the airbag is disposed on the cover 2, and the sealing plate 4 is connected to the bottom of the airbag. By controlling the expansion of the airbag, the sealing plate 4 is driven to overcome the restoring force of the elastic member 51 and move downward away from the cover 2 as a whole, thereby sealing the manhole 11. Alternatively, by controlling the contraction of the airbag, the sealing plate 4 can be moved upward toward the cover under the restoring force of the elastic member 51 and open the manhole 11 as a whole, thereby facilitating control and eliminating the need for manual opening and closing of the manhole 11. The airbag is connected to an air channel 61, which is connected to an air reservoir 63. An air source control switch 62 is provided on the air channel 61. The airbag is inflated or depressurized by adjusting the air source control switch 62.

[0074] In some other embodiments, the second adjustment device 6 includes a plurality of adjustment bolts 64, which are threadedly connected to the cover body 2 at intervals, one end of the adjustment bolt 64 abuts against the sealing plate 4, and the side of the adjustment bolt 64 facing away from the sealing plate 4 extends out of the cover body 2 and is provided with a butterfly structure 641. Specifically, the adjustment bolt 64 extends up and down, and the top and bottom ends of the adjustment bolt 64 are respectively arranged above and below the cover body 2. The top end of the adjustment bolt 64 is provided with a butterfly structure 641, and the bottom end of the adjustment bolt 64 abuts against the sealing plate 4. Under the action of the reset force of the elastic member 51, the top surface of the sealing plate 4 can always maintain contact with the lower end of the adjustment bolt 64. By adjusting the engagement of the plurality of adjustment bolts 64 on the cover body 2, the upper and lower positions of the sealing plate 4 relative to the cover body 2 can be adjusted.

[0075] In this embodiment, the second adjusting device 6 includes both an airbag and an adjusting bolt 64. When the on-site gas source conditions permit, the airbag can be selected as the second adjusting device 6 to adjust the position of the sealing plate 4. When there is no gas source on site, the adjusting bolt 64 can be selected as the second adjusting device 6 to adjust the position of the sealing plate 4, thereby improving the applicability of the tank container of this application.

[0076] Further, refer to Figure 6 The tank box also includes at least one first pressing member, which is arranged on one side of the outer periphery of the cover body 2, extends downward, and the bottom end of the first pressing member extends toward the middle of the cover body 2 to form a first pressing block 71. The top surface of the first pressing block 71 can be pressed against the tank body 1 when the cover body 2 is rotated to a position relative to the manhole 11. Specifically, the first pressing member is arranged on the cover body 2 and extends downward. After the cover body 2 is rotated to a position relative to the manhole 11, the top surface of the first pressing block 71 at the bottom of the first pressing member can be opposite to the tank body 1. When the second adjusting device 6 controls the sealing plate 4 to move downward and seal the manhole 11, because the second adjusting device 6 is arranged on the cover body 2, the cover body 2 will receive a reaction force of upward movement, and the top surface of the first pressing block 71 of the first pressing member can be pressed against the tank body 1, thereby preventing the cover body 2 from moving upward relative to the tank body 1, limiting the distance between the cover body 2 and the tank body 1, so that the cover body 2 can drive the sealing plate 4 to seal the manhole 11, thereby ensuring the sealing effect of the manhole 11. Furthermore, the first pressing member is arranged on a side of the cover body 2 facing away from the manhole 11 to prevent the first pressing member from interfering with the rotation of the cover body 2 .

[0077] Further, refer to Figure 5The tank box also includes at least one second pressing member 81, which is provided on the tank body 1 and is located on the outer circumference of the manhole 11. The second pressing member 81 extends upward, and the top end of the second pressing member 81 extends toward the direction close to the manhole 11 to form a second pressing block 81. The second pressing block 81 can abut against the cover body 2 when the cover body 2 is rotated to a position relative to the manhole 11. Specifically, the second pressing member 81 is provided on the tank body 1 and extends upward. After the cover body 2 is rotated to a position relative to the manhole 11, the bottom surface of the second pressing block 81 at the top of the second pressing member 81 can be opposite to the cover body 2. When the second adjusting device 6 controls the sealing plate 4 to move downward and seal the manhole 11, when the cover body 2 receives the reaction force of the upward movement, the bottom surface of the second pressing block 81 of the second pressing member 81 can abut against the cover body 2 to prevent the cover body 2 from moving upward, thereby ensuring the sealing effect of the manhole 11.

[0078] Reference Figure 2 and Figure 6 In this embodiment, four first pressing members are arranged at intervals, and two second pressing members 81 are arranged at intervals. The four first pressing members are arranged on the side of the cover body 2 opposite to the rotation trajectory close to the manhole 11 to prevent the first pressing members from interfering with the rotation of the cover body 2. The two second pressing members 81 are arranged on the outer circumference of the tank body 1 around the manhole 11, and the two second pressing members 81 are located at the ends of the trajectory of the cover body 2 rotating toward the manhole 11 to prevent the second pressing members 81 from interfering with the rotation of the cover body 2.

[0079] In some specific embodiments, when it is necessary to remotely open the manhole 11 on the top of the tank body 1, the airbag is first depressurized so that the sealing plate 4 moves up close to the cover body 2 under the action of the restoring force of the compression spring, and then the soft shaft retraction structure 34 is adjusted so that the soft shaft rope slides along the slide of the kit 31, and then the first pull rod 32 is pulled so that the first pull rod 32 retracts along the movable sleeve rod 312, so that the first pull rod 32 can pull the cover body 2 to rotate, thereby opening the cover body 2 to the manhole 11. When the manhole 11 needs to be closed remotely, first adjust the flexible shaft retracting structure 34 so that the flexible shaft rope slides along the slideway of the kit 31, and then push the first pull rod 32 so that the first pull rod 32 extends along the movable sleeve rod 312 and pushes the cover body 2 to rotate until the cover body 2 rotates to the top of the manhole 11. Then, inflate the airbag so that the airbag expands and overcomes the elastic reset force of the compression spring to move the sealing plate 4 downward to achieve sealing of the manhole 11. At this time, the first clamping member and the second clamping member 81 can pull the cover body 2 and the tank box to prevent the cover body 2 from moving upward relative to the tank box. In some other specific embodiments, the manhole 11 can be sealed by rotating the adjusting bolt 64 on the cover body 2, or the sealing plate 4 can be moved upward by rotating the adjusting bolt 64 and cooperating with the compression spring.
