Description

Technical Field

[0001] The utility model relates to the field of tank containers, in particular to an anti-falling device for a tank container and a tank container. Background Art

[0002] At present, the manhole of the tank body in a tank container is usually arranged at the top of the tank body. A frame is arranged around the tank body to facilitate the operator to climb to the top of the tank body, open the manhole cover of the tank body, and perform liquid filling operations.

[0003] Since the height from the ground to the top of the tank body is relatively large, handrails are provided on the frame at the top of the current tank body. When the operator climbs onto the frame at the top of the tank body to perform liquid filling operations, a safety rope needs to be worn. The operator buckles the safety rope buckle on the horizontal pipe of the handrail to prevent the operator from accidentally falling and causing safety accidents.

[0004] However, since the operator buckles the safety rope buckle on the horizontal pipe of the handrail, it cannot achieve the effect of completely locking the safety rope buckle, and there is a risk of the safety rope buckle sliding. If the safety rope is set too long, there is still a risk that the operator will fall to the ground. Summary of the Utility Model

[0005] Aiming at the problems existing in the above-mentioned prior art, the purpose of the utility model is to provide an anti-falling device for a tank container and a tank container, which is convenient for an operator to fix a safety rope when operating on the top of the tank container.

[0028] Next, the technical solution of the present utility model will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0030] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] As Figure 1 shown, the present utility model discloses a fall prevention device for a tank container, which is mainly used for a small tank container. The fall prevention device for the tank container includes a first rod 1, a second rod 2, a safety rope fixing buckle 3, and a locking mechanism. The first rod 1 is fixed on the tank container, the first rod 1 and the second rod 2 are telescopically connected, the safety rope fixing buckle 3 is arranged on the second rod 2, and the locking mechanism is used to lock the relative positions of the first rod 1 and the second rod 2.

[0032] During the use of the fall prevention device for the tank container of the present utility model, the operator climbs to the top of the tank container, extends the second rod 2 relative to the first rod 1, adjusts the second rod 2 to a suitable position, and locks the relative positions of the first rod 1 and the second rod 2 with the locking mechanism. Subsequently, the operator fixes the safety rope on the safety rope fixing buckle 3. Since the position of the second rod 2 is locked by the locking mechanism, and the safety rope fixing buckle 3 is a ring-shaped fixing buckle, compared with the scheme of fixing on the handrail, the safety rope buckle is not easy to slide, and the operator can safely work on the top of the tank container. After the operator finishes the work, unlock the locking mechanism, retract the second rod 2 relative to the first rod 1, and then lock the locking mechanism again. The fall prevention device for the tank container of the present utility model is especially suitable for use on small tank containers, and only one such fall prevention device for the tank container can meet the needs of the operator. The fall prevention device for the tank container of the present utility model can also be used on large tank containers. In this case, multiple such fall prevention devices for the tank containers need to be arranged at intervals to meet the safety rope fixing requirements.

[0033] Therefore, through the telescopic arrangement of the first rod 1 and the second rod 2 and the arrangement of the locking mechanism in the present utility model, when the operator works on the top of the tank container, the second rod 2 can be adjusted to a suitable position, and the safety rope can be fixed on the safety rope fixing buckle 3 located on the second rod 2. While the operation is convenient, the safety rope fixing buckle 3 is small in volume, can completely lock the safety rope buckle, and can ensure the safety of the operator.

[0034] In this embodiment, as Figures 1 to 6 shown, both the first rod 1 and the second rod 2 are tubular, and the first rod 1 is sleeved outside the second rod 2. By setting both the first rod 1 and the second rod 2 to be tubular, when the anti-falling device of the tank container of the present invention is not in use, the second rod 2 can be retracted into the first rod 1, effectively reducing the volume of the anti-falling device of the tank container. In other embodiments, the first rod 1 and the second rod 2 can also be set as solid cylinders, and the first rod 1 and the second rod 2 can be telescopically connected by an elastic member.

[0035] In this embodiment, as Figures 1 to 4 shown, one end of the first rod 1 is provided with a sealing plate 4, the sealing plate 4 shields the opening at one end of the first rod 1, the sealing plate 4 is provided with an opening, and the shape of the opening is the same as the shape of the radial cross-section of the second rod 2, and the second rod passes through the opening. By providing the sealing plate 4 and defining the shape of the opening, the present invention has a guiding effect on the second rod 2, facilitating the telescopic movement of the second rod 2 while keeping the inside of the tube body of the first rod 1 closed, and preventing dust from entering the inside of the tube body of the first rod 1 through the gap between the first rod 1 and the second rod 2. In other embodiments, the first rod 1 and the second rod 2 can be connected by a flexible blocking ring, and the flexible blocking ring fills the gap between the first rod 1 and the second rod 2, which can also prevent dust from entering the inside of the tube body of the first rod 1.

[0036] In this embodiment, as Figure 1 , Figure 5 and Figure 6 shown, the safety rope fixing buckle 3 is arranged at the first end of the second rod 2, and the first end is far away from the first rod 1, that is, as the second rod 2 extends out of the first rod 1, the first end gradually moves away from the first rod 1. By arranging the safety rope fixing buckle 3 at one end of the second rod 2 far away from the first rod 1, the present invention facilitates the operator to fix the safety rope buckle. In other embodiments, the safety rope fixing buckle 3 can also be arranged on the tube wall of the first rod 1.

[0037] In this embodiment, as Figures 1 to 8As shown, the locking mechanism includes a first fixing hole provided on the first rod 1, a plurality of second fixing holes 5a provided on the second rod 2, and a locking pin rod 5b. Each of the second fixing holes 5a is arranged in sequence along the axis direction of the second rod 2. The locking pin rod 5b passes through the first fixing hole and any one of the second fixing holes 5a at the same time to lock the relative positions between the first rod 1 and the second rod 2. During use, when it is necessary to extend and retract the first rod 1 and the second rod 2, the locking pin rod 5b is removed from the first rod 1 and the second rod 2, so that the first rod 1 can extend and retract relative to the second rod 2. When the second rod 2 extends and retracts to the required position, the nearest second fixing hole 5a is aligned with the first fixing hole, and then the locking pin rod 5b passes through the first fixing hole and the second fixing hole 5a in sequence to lock the relative positions between the first rod 1 and the second rod 2. By providing a plurality of second fixing holes 5a in the present utility model, multiple relative positions between the first rod 1 and the second rod 2 can be locked, and the operation is convenient by inserting the locking pin rod 5b into the first fixing hole and the second fixing hole 5a. In other embodiments, waist slots can also be provided on both the first rod 1 and the second rod 2, and a butterfly bolt can be used to fix the waist slots provided on the first rod 1 and the second rod 2 respectively.

[0038] In this embodiment, as Figure 7 and Figure 8As shown, the locking latch rod 5b is provided with a limiting block 5c protruding in the radial direction. Limiting holes 5d for the limiting block 5c to pass through are provided on both the first rod 1 and the second rod 2. The limiting hole 5d on the first rod 1 communicates with the first fixing hole, and the limiting hole 5d on the second rod 2 communicates with the second fixing hole 5a. During use, when it is necessary to lock the relative positions of the first rod 1 and the second rod 2, the locking latch rod 5b together with the limiting block 5c is passed through the limiting hole 5d on the first fixing hole and the first rod 1, and the locking latch rod 5b together with the limiting block 5c is passed through the second fixing hole 5a and the limiting hole 5d on the second rod 2. Then, the locking latch rod 5b is rotated along its axis, so that the limiting block 5c and the limiting hole 5d are arranged in a staggered manner. And only a blocking member needs to be arranged on the side away from the limiting block 5c, and the blocking member cannot pass through the limiting hole 5d on the first fixing hole and the first rod 1, then the locking of the relative positions of the first rod 1 and the second rod 2 can be realized. Through the arrangement of the limiting block 5c and the limiting hole 5d, in the process of the locking latch rod 5b locking the relative positions of the first rod 1 and the second rod 2, the locking latch rod 5b is not easily disengaged. In other embodiments, a limiting groove may also be provided on the locking latch rod 5b, and a limiting pin may be provided on the first rod 1. Through the cooperation of the limiting groove and the limiting pin, the locking latch rod 5b is not easily disengaged.

[0039] In this embodiment, as Figure 7 shown, a rotating handle 5e is provided at the first end of the locking latch rod 5b, and the rotating handle 5e is rod-shaped. Through the arrangement of the rotating handle 5e, the rotating handle 5e can be rotated to realize the self-rotation of the locking latch rod 5b along its axis, and further make the limiting block 5c and the limiting hole 5d arranged in a staggered manner. In other embodiments, a circular rotating handle may also be used to replace the rotating handle 5e.

[0040] In this embodiment, as Figure 7As shown, the limiting block 5c is arranged near the second end of the locking bolt rod 5b, and the handle 5e is arranged obliquely to the axis of the locking bolt rod 5b. When the locking bolt rod 5b passes through the first fixing hole and any one of the second fixing holes 5a at the same time and the handle 5e droops due to gravity, the limiting block 5c is arranged in a dislocation manner with the limiting hole 5d. The orientation of the locking bolt rod 5b is the same as that of the limiting block 5c, and the limiting hole 5d is arranged above the first fixing hole and the second fixing hole 5a. After the locking bolt rod 5b passes through the first fixing hole and the second fixing hole 5a, the handle 5e can automatically droop due to gravity, and the limiting block 5c and the limiting hole 5d can be automatically arranged in a dislocation manner. In the present utility model, by arranging the handle 5e obliquely to the axis of the bolt rod 5b, it is convenient for the handle 5e to automatically droop due to gravity, thereby realizing the dislocation of the limiting block 5c and the limiting hole 5d. In other embodiments, the orientation of the locking bolt rod 5b may also be different from that of the limiting block 5c.

[0041] In this embodiment, as Figure 7 shown, the first rod 1 includes a pipe body portion 1a and a fixing plate 1b connected to the first end of the pipe body portion 1a. The first fixing hole and the limiting hole 5d communicated with the first fixing hole are both arranged on the fixing plate 1b, and the sealing plate 4 is arranged at the second end of the pipe body portion 1a. There are two fixing plates 1b, and the fixing plates 1b are arranged oppositely, and the first fixing hole and the limiting hole 5d communicated with the first fixing hole are arranged on each fixing plate 1b. There are also two second fixing holes 5a and the limiting holes 5d communicated with the second fixing holes 5a. Through the arrangement of the fixing plate 1b in the present utility model, the second fixing hole 5a located on the second rod 2 can be exposed within the visual field range, which is convenient for the locking bolt rod 5b to pass through the first fixing hole and the second fixing hole 5a; and the paired arrangement of the first fixing hole and the second fixing hole 5a makes the locking of the relative positions between the first rod 1 and the second rod 2 more stable. In other embodiments, the first fixing hole and the limiting hole 5d communicated with the first fixing hole may also be arranged on the pipe body portion 1a.

[0042] Since the anti-falling device of the tank container of the present utility model is used in a tank container, the present utility model also discloses a tank container. The tank container includes a top frame, a bottom frame, side beams, a tank body, and the anti-falling device of the tank container in this embodiment. The tank body is arranged between the top frame and the bottom frame, the side beams connect the top frame and the bottom frame, and the side beams are arranged in the height direction. In this embodiment, the first rod 1 is fixed on the side beam, the first rod 1 is arranged in the height direction, and the second rod 2 has a first position and a second position. When in the first position, the safety rope fixing buckle 3 is located between the top frame and the bottom frame. When in the second position, the safety rope fixing buckle 3 is located on one side of the top frame away from the bottom frame. By fixing the first rod 1 on the side beam, when the anti-falling device of the tank container is not in use, the safety rope fixing buckle 3 can be retracted below the top frame along with the second rod 2, reducing the top space of the tank container. When operation is required, the safety rope fixing buckle 3 can be raised above the top frame along with the second rod 2. In other embodiments, the first rod 1 can also be fixed on the top frame, and the first rod 1 is rotatably connected to the top frame. When the anti-falling device of the tank container is not needed, the first rod 1 is rotated to be parallel to the plane where the top frame is located; when the anti-falling device of the tank container is needed, the first rod 1 is rotated to be perpendicular to the plane where the top frame is located.

[0043] In summary, the anti-falling device of the tank container of the present utility model, through the telescopic arrangement of the first rod 1 and the second rod 2, and through the arrangement of the locking mechanism, enables the operator to adjust the second rod 2 to a suitable position when working on the top of the tank container, and fix the safety rope on the safety rope fixing buckle 3 located on the second rod 2. While the operation is convenient, the safety rope fixing buckle 3 is small in volume, can completely lock the safety rope buckle, and can ensure the safety of the operator. By setting both the first rod 1 and the second rod 2 in a tubular shape, when the anti-falling device of the tank container of the present utility model is not in use, the second rod 2 can be retracted into the first rod 1, effectively reducing the volume of the anti-falling device of the tank container. And through the arrangement of the sealing plate 4 and the limitation of the shape of the opening, it has a guiding effect on the second rod 2, facilitates the telescopic movement of the second rod 2, and at the same time closes the inside of the tube body of the first rod 1, preventing dust from entering the inside of the tube body of the first rod 1 through the gap between the first rod 1 and the second rod 2. By setting the safety rope fixing buckle 3 at one end of the second rod 2 away from the first rod 1, it is convenient for the operator to fix the safety rope buckle. By setting a number of second fixing holes 5a, multiple relative positions between the first rod 1 and the second rod 2 can be locked, and by inserting the locking pin rod 5b into the first fixing hole and the second fixing hole 5a, the operation is convenient. Through the arrangement of the limiting block 5c and the limiting hole 5d, when the locking pin rod 5b locks the relative positions of the first rod 1 and the second rod 2, the locking pin rod 5b is not easily disengaged. Through the arrangement of the rotating handle 5e, the rotating handle 5e can be rotated to realize the self-rotation of the locking pin rod 5b along its axis, and then the limiting block 5c and the limiting hole 5d are arranged in a dislocation manner. By setting the rotating handle 5e obliquely to the axis of the pin rod 5b, it is convenient for the rotating handle 5e to automatically droop under gravity, and then the limiting block 5c and the limiting hole 5d are dislocated. Through the arrangement of the fixing plate 1b, the second fixing hole 5a located on the second rod 2 can be exposed within the visual range, facilitating the locking pin rod 5b to pass through the first fixing hole and the second fixing hole 5a; and the paired arrangement of the first fixing hole and the second fixing hole 5a makes the locking of the relative positions between the first rod 1 and the second rod 2 more stable. For the tank container of the present utility model, by fixing the first rod 1 on the side beam, when the anti-falling device of the tank container is not in use, the safety rope fixing buckle 3 can be retracted below the top frame along with the second rod 2, reducing the top space of the tank container. When work is required, the safety rope fixing buckle 3 rises above the top frame.

[0044] It should be emphasized that the above is only the preferred embodiment of the present utility model, and it is not subject to any form of limitation on the present utility model. Any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
