[0031] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0032] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0033] When describing the orientation, the present invention takes the length direction of the tank container as the longitudinal direction and the width direction of the tank container as the transverse direction.

[0034] The present invention provides a tank container, comprising a tank body, a frame supported outside the tank body, and a handrail device 2 arranged on the top of the frame.

[0035] The frame comprises two end frames arranged at intervals, a top side beam connecting the tops of the two end frames, a plurality of top cross beams connecting the two side beams, and two walkways 1 parallel to the top side beams.

[0036] The walkway 1 extends in the longitudinal direction. Specifically, the walkway 1 includes a walkway board 11 extending in the longitudinal direction and a walkway connector connected to both sides of the walkway board 11. The walkway connector includes a top board and a side board 12 vertically connected to each other. The top board is horizontally arranged and connected to the side of the walkway board 11. The side board 12 is vertically arranged and connected to the other side of the top board relative to the walkway board 11. The side board 12 has an assembly hole, and the axis of the assembly hole extends in the transverse direction.

[0037] In this embodiment, two handrail railing devices 2 are respectively arranged on both sides of the top of the tank body. In other embodiments, the handrail railing device 2 can also be arranged on one side of the top of the tank body as required.

[0038] The handrail device 2 includes a handrail, a blocking frame 23 , a bracket 25 and a limiting member 24 .

[0039] The handrail comprises a horizontal rod 21 and a plurality of vertical rods 22 arranged at intervals.

[0040] The horizontal rod 21 extends in the longitudinal direction, that is, the horizontal rod 21 is parallel to the walkway 1. In this embodiment, the horizontal rod 21 is cylindrical, that is, the cross section of the horizontal rod 21 is circular.

[0041] The top end of the vertical rod 22 is rotatably connected to the horizontal rod 21 , and the bottom end is rotatably connected to the walkway 1 .

[0042] The vertical rod 22 and the horizontal rod 21 are rotatably connected through a hoop and a perforated plate. Specifically, a perforated plate is fixed to the top of the vertical rod 22, and the perforated plate extends along the axis of the vertical rod 22. An opening is provided on the perforated plate, and the axis of the opening is perpendicular to the axis of the vertical rod 22.

[0043] A plurality of clamps are arranged at longitudinal intervals on the outer periphery of the horizontal rod 21, and the clamps are arranged corresponding to the orifice plate. Specifically, the clamp includes a clamp body and two ears. In the present embodiment, the clamp body is in an arc shape, and is sleeved on the outer periphery of the horizontal rod 21 to match the outer periphery of the horizontal rod 21. The two ears are respectively connected to the two ends of the clamp body. In the present embodiment, the ears are connected to the ends of the clamp body and extend vertically downward. An assembly hole is provided on the ear, and the axis of the assembly hole extends laterally. When the clamp body is sleeved on the outer periphery of the horizontal rod 21, the two ears extend downward beyond the bottom of the horizontal rod 21.

[0044] When the vertical rod 22 is connected to the horizontal rod 21 , the orifice plate is located between the two ears, and the fasteners penetrate the assembly holes on the ears and the openings on the orifice plate to achieve a rotatable connection between the top end of the vertical rod 22 and the horizontal rod 21 .

[0045] In this embodiment, the fastener includes a bolt and a nut, the bolt passes through the assembly hole and the opening, and the nut is screwed on. The nut does not need to completely lock the orifice plate and the lug, and only needs to stop the orifice plate and the lug from falling off, so that the vertical rod 22 is connected to the horizontal rod 21 and can also rotate around the bolt.

[0046] The bottom end of the vertical rod 22 is rotatably connected to the walkway 1. Specifically, in the present embodiment, the bottom end of the vertical rod 22 is fixedly connected with a connecting rod, and the connecting rod is arranged horizontally. The connecting rod is connected to the walkway 1 through an assembly plate. The assembly is provided with a transverse assembly hole corresponding to the assembly hole on the walkway 1, and fasteners are provided through the transverse assembly hole and the assembly hole to realize a detachable connection. The assembly extends downwardly beyond the walkway 1, and a rotating hole is provided on the portion extending downwardly, the connecting rod is located below the walkway 1, and is provided in the rotating hole, so as to realize a rotatable connection between the connecting rod and the assembly plate. The connecting rod is stopped by a pin shaft so as to prevent the connecting rod from falling out of the rotating hole.

[0047] The retaining frame 23 is arranged on the outside of the walkway 1. In the transverse direction, the direction in which the two walkways 1 face each other is the inside, and the direction in which the two walkways 1 depart from each other is the outside. Unless otherwise specified, the definitions of the inside and the outside are consistent with those herein. In this embodiment, the number of retaining frames 23 is two, and they are arranged at intervals along the length direction of the walkway 1, that is, the retaining frames 23 are arranged at intervals along the longitudinal direction. In other embodiments, the number of retaining frames 23 can also be one, three, or other numbers, which can be set according to actual needs.

[0048] Each retaining frame 23 is connected to the walkway 1 and protrudes out of the outside of the walkway 1 .

[0049] See also Figure 6 Specifically, each retaining frame 23 includes a connecting plate 231 and a stopper plate 232. The connecting plate 231 extends vertically, and is provided with connecting holes corresponding to the assembly holes on the walkway 1. The connecting plate 231 is closely attached to the side plate 12 of the walkway 1, and fasteners penetrate the assembly holes and the connecting holes to achieve a detachable connection between the connecting plate 231 and the walkway 1. In other embodiments, the connecting plate 231 can also be welded to the walkway 1.

[0050] A receiving hole is formed on the connecting plate 231. In this embodiment, the receiving hole passes through the top side of the connecting plate 231. The diameter of the receiving hole increases gradually from the top to the bottom.

[0051] Specifically, a connecting hole is respectively provided on both sides of the accommodating hole, and the two connecting holes are symmetrically arranged with respect to the accommodating hole.

[0052] The connecting plate 231 is also provided with a rotating hole, which is located below the accommodating hole and is used for the connecting rod to pass through.

[0053] The stop plate 232 includes a stop portion 2321 and mounting portions 2322 symmetrically arranged at both ends of the stop portion 2321. A stop opening is arranged on one side of the stop portion 2321, and the stop opening faces the length direction of the walkway 1, i.e., the longitudinal direction, so that the vertical rod 22 can enter the stop opening, and then the stop plate 232 stops the vertical rod 22 in the vertical state. When the handrail is folded and retracted, the vertical rod 22 can exit the stop opening and rotate to the folded and retracted state.

[0054] The two mounting portions 2322 are formed by bending the two ends of the stopper opening upwards. Specifically, the length of each mounting portion 2322 gradually increases from the top to the bottom, and matches the receiving hole on the connecting plate 231, so that the mounting portion 2322 can be detachably embedded in the receiving hole.

[0055] The mounting portion 2322 is provided with a mounting hole, and a fastener is inserted through the mounting hole and the assembly hole on the walkway 1 to realize the detachable connection between the stop plate 232 and the walkway 1, that is, the stop plate 232 and the connecting plate 231 are detachably connected to the walkway 1. After the stop plate 232 and the connecting plate 231 are both connected to the walkway 1, the mounting portion 2322 of the stop plate 232 is embedded in the receiving hole of the connecting plate 231, and the mounting portion 2322 located in the receiving hole is flush with the connecting plate 231. After the retaining frame 23 is connected to the walkway 1, the stop portion 2321 protrudes out of the outside of the walkway 1.

[0056] In this embodiment, there is an arc transition between the mounting portion 2322 and the stopping portion 2321 .

[0057] Furthermore, the stop plate 232 further includes a reinforcing folded edge 2324. The reinforcing folded edge 2324 is formed by bending a side of the stop portion 2321 away from the stop hole 2323. The reinforcing folded edge 2324 and the stop portion 2321 are in arc transition.

[0058] In each baffle frame 23, the connecting plate 231 and the stop plate 232 are detachably connected, the two sides of the connecting plate 231 are mirror-symmetrical, the two mounting parts 2322 of the stop plate 232 are mirror-symmetrical, and the connecting plate 231 and the mounting parts 2322 are respectively detachably connected to the walkway 1, so that when the baffle frame 23 is installed on the walkway 1, it can be installed not only on the left side of the walkway 1, but also on the right side of the walkway 1, that is, the baffle frame 23 can be used on both the left and right sides at the same time, which improves the versatility of the baffle frame 23 and makes it easy to install and maintain.

[0059] The limiter 24 is used to limit the state of the vertical rod 22 when it is erected, so that the vertical rod 22 remains in the erected state. In this embodiment, there are two limiters 24, which are respectively located on both sides of the tank body, that is, one handrail corresponds to one limiter 24, and the limiter 24 is located at the rear end, so that when the operator goes from the rear end of the tank container to the top of the tank body, he can erect and unfold the handrail in time and stabilize the vertical rod 22 through the limiter 24, thereby ensuring the safety of the operator on the top of the tank body.

[0060] In other embodiments, the number of the limiting members 24 may be three, four or other numbers, and the limiting members 24 on each side are arranged at intervals in the longitudinal direction.

[0061] See also Figure 7 The limiting member 24 includes a fixed plate 241 and a limiting plate 242 which are hinged to each other, and a locking block 243. The fixed plate 241 is connected to the outer side of the walkway 1. The limiting plate 242 is hinged to the upper side of the fixed plate 241 so that the limiting plate 242 can be rotated from top to bottom to a horizontal position and locked and fixed in the horizontal position.

[0062] The fixing plate 241 extends vertically, closely attached to the side plate 12 of the walkway 1 and connected and fixed to the side plate 12. The fixing plate 241 is provided with bolt mounting holes, and the side plate 12 of the walkway 1 is provided with bolt connection holes. Fasteners penetrate the bolt mounting holes and the bolt connection holes to realize the detachable connection between the fixing plate 241 and the walkway 1.

[0063] A first sleeve is disposed at the top of the fixing plate 241, and the axis of the first sleeve extends in the longitudinal direction. In this embodiment, a plurality of first sleeves are disposed at intervals in the longitudinal direction at the top of the fixing plate 241.

[0064] The limiting plate 242 has a second sleeve on one side and a limiting slot on the other side. In this embodiment, a plurality of second sleeves are arranged at intervals along the length direction of the limiting plate 242, and the second sleeves are matched with the first sleeves.

[0065] When the limiting plate 242 is connected to the fixed plate 241, the axis of the second sleeve is extended longitudinally, the first sleeve and the second sleeve are placed alternately, and the rotating shaft is inserted into the first sleeve and the second sleeve to realize the rotatable connection between the limiting plate 242 and the fixed plate 241, thereby realizing the rotatable connection of the limiting plate 242 relative to the walkway 1.

[0066] The limiting slot has an opening that is away from the direction of the second sleeve, and the opening enables the vertical rod 22 to enter or exit the limiting slot. Specifically, when the limiting plate 242 is in a horizontal position, the opening faces the vertical rod 22.

[0067] Furthermore, along the length direction of the limit plate 242, the width of the limit plate 242 gradually changes, so that one side wall of the opening of the limit slot exceeds the other side wall, so that the vertical rod 22 inserted into the limit slot is not easy to fall out when the limit plate 242 is in the horizontal position. In this example, the width gradually increases from the front end to the rear end along the longitudinal direction, so that the side wall of the limit slot at the rear end exceeds the side wall of the limit slot at the front end.

[0068] The locking block 243 is located between the limiting plate 242 and the fixing plate 241, and the locking block 243 is perpendicular to the fixing plate 241, that is, the locking block 243 extends horizontally, and the locking block 243 protrudes outward from the outside of the fixing plate 241, so that when the limiting plate 242 is in a horizontal position, the bottom surface of the limiting plate 242 abuts against the locking block 243, so that the limiting plate 242 is locked in a horizontal position. At this time, the opening of the limiting slot faces the vertical rod 22, and can clamp and fix the vertical rod 22 in an upright state to keep the handrail in an unfolded state.

[0069] Specifically, along the longitudinal direction, a plurality of locking blocks 243 are arranged at intervals. In this embodiment, the number of the locking blocks 243 is three.

[0070] When the limiting plate 242 flips upward to make the vertical rod 22 escape from the limiting slot, the vertical rod 22 can rotate downward to retract the handrail.

[0071] Furthermore, a limiting hole is provided on the first sleeve, and the limiting hole extends in the transverse direction. A limiting pin 244 is provided on the rotating shaft, and the limiting pin 244 is perpendicular to the axis of the rotating shaft. The limiting pin 244 is inserted into the limiting hole to limit the flipping angle of the limiting plate 242.

[0072] The shaft is provided with two blind holes, which are symmetrically arranged about the axis of the shaft. Specifically, in this embodiment, the axis of the blind hole extends along the radial direction of the shaft. The limit pin 244 is inserted into the blind hole, and limits the flip angle of the limit plate 242 by abutting against the first sleeve.

[0073] The symmetrical arrangement of the two blind holes allows the limit pins 244 to be inserted into the two blind holes respectively when the fixing plate 241 and the limit plate 242 are hinged, so that the limit member 24 can be applied to both sides, thereby improving the versatility of the limit member 24 and making installation and maintenance convenient.

[0074] The bracket 25 is used to support the horizontal bar 21 when the handrail is folded, so that the horizontal bar 21 is in a horizontal state. In this embodiment, there are two brackets 25, which are respectively located on both sides of the tank body, that is, one handrail corresponds to one bracket 25. In this embodiment, the bracket 25 is located at the front end, that is, the bracket 25 and the limiter 24 are respectively arranged at the front and rear ends of the frame.

[0075] See also Figure 8The bracket 25 includes a transition plate 251 and a supporting plate 252 .

[0076] The transition plate 251 extends vertically, closely attached to the side plate 12 of the walkway 1 and connected and fixed to the side plate 12. The fixing plate 241 is provided with bolt mounting holes, and the side plate 12 of the walkway 1 is provided with bolt connection holes. Fasteners penetrate the bolt mounting holes and the bolt connection holes to realize the detachable connection between the transition plate 251 and the walkway 1.

[0077] The supporting plate 252 extends horizontally and is fixedly connected to the transition plate 251. The other end of the supporting plate 252 relative to the transition plate 251 is bent upward to form a limiting fold to prevent the horizontal rod 21 on the supporting plate 252 from sliding outward.

[0078] The end of the supporting plate 252 facing away from the transition plate 251 also has a baffle 254 that bends and extends upward to block the horizontal rod 21 on the supporting plate 252 from moving in the lateral direction.

[0079] Furthermore, one side of the supporting plate 252 has a reinforcing folded edge 253 , and the reinforcing folded edge 253 is formed by bending the side edge of the supporting plate 252 downward.

[0080] In this embodiment, when the reinforced folded edge 253 of the bracket 25 is installed on the left and right sides respectively, the reinforced folded edge 253 of one bracket 25 is located in front of the supporting plate 252, and the reinforced folded edge 253 of the other bracket 25 is located behind the supporting plate 252, which does not affect the function of the bracket 25 to support the horizontal rod 21.

[0081] In another embodiment, see Fig. 9 The receiving hole on the connecting plate 231 of the retaining frame 23 is closed on all sides, that is, the receiving hole has inner side walls on all sides, and the mounting portion 2322 is embedded in the receiving hole.

[0082] In yet another embodiment, see Fig.10 A plurality of connection holes are provided on the connection plate 231 of the retaining frame 23. A plurality of installation holes corresponding to the plurality of connection holes are provided on the installation portion 2322, the installation portion 2322 is attached to the connection plate 231, the connection plate 231 is attached to the side plate 12 of the walkway 1, and the fasteners penetrate the installation holes, the connection holes and the assembly holes on the side plate 12 of the walkway 1 to realize the detachable connection between the connection plate 231, the stop plate 232 and the walkway 1.

[0083] It can be seen from the above technical solution that the advantages and positive effects of the present invention are:

[0084] The handrail device of the present invention includes a handrail and a blocking frame. The handrail includes a horizontal bar and a plurality of vertical bars arranged at intervals; the horizontal bar extends in the longitudinal direction; the top end of each vertical bar is rotatably connected to the horizontal bar, and the bottom end is rotatably connected to the top of the frame; the blocking frame includes a connecting plate and a stopper plate, the connecting plate is used to be connected and fixed to the frame, the stopper plate includes a horizontally extending stopper portion and mounting portions symmetrically arranged at both ends of the stopper portion, and a stopper opening is provided on one side of the stopper portion; any one of the two mounting portions is detachably connected to the connecting plate, so that the stopper opening faces the length direction of the frame and can stop the vertical bar located in the stopper opening.
