Detailed Description

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

As shown in fig. 1, 2, 4 and 5, the floor panel of the present embodiment includes: a first flooring module 10, a second flooring module 20, and a friction reducing structure 30. Wherein, the first floor module 10 comprises a plurality of floor modules; the second floor module 20 includes a plurality of first floor modules 10 and the second floor modules 20, which are alternately arranged in the preset direction n; the anti-friction structure 30 includes a multi-directional anti-friction structure 31 provided on the first floor module 10 and a one-directional anti-friction structure 32 provided on the second floor module 20.

Use the technical scheme of this embodiment, set up antifriction structure 30 on the floor, antifriction structure 30 can greatly reduced the frictional force between goods and the floor to the goods of being convenient for move on the floor. Therefore, when the goods are stacked, the container device 80 for loading the goods can be pushed by manpower, and the stacking efficiency of the goods can be improved in the mode, so that the loading and unloading efficiency of the goods is improved. On the other hand, the damage to the lining of the box wagon caused by the forklift can be avoided, and the maintenance cost of the box wagon is reduced. The friction reducing structure 30 includes a one-way friction reducing structure 32 and a multi-way friction reducing structure 31, and the one-way friction reducing structure 32 can reduce the friction between the cargo and the floor when the cargo moves horizontally (in the direction of n or the direction opposite to n in the figure). The multi-directional friction reducing structure 31 can reduce the frictional force between the cargo and the floor when the cargo moves in all directions in the horizontal plane. When loading goods, can place container utensil 80 on first floor module 10 earlier, because set up multidirectional antifriction structure 31 on the first floor module 10, consequently operating personnel can carry out the gesture to container utensil 80 and adjust, again with container utensil 80 along preset direction n or with preset direction n to the opposite direction on second floor module 20. Taking the example that the first floor module 10 and the second floor module 20 both include 2, when placing the container device 80, two container devices 80 can be placed on the first floor module 10 between the two second floor modules 20, after the posture of the container device 80 is adjusted, the first container device 80 is pushed onto the second floor module 20 at the front end of the first floor module 10, and the second container device 80 is pushed onto the second floor module 20 at the rear end of the first floor module 10. The third container 80 is placed on the first floor module 10 located at the end, and after the posture of the third container 80 is adjusted, the third container 80 is pushed onto the second floor module 20 where the second container 80 is located. The unloading process of the cargo is the reverse process of the loading process, and is not described herein. The floor arrangement of this embodiment can realize loading and unloading at least three collection dress utensil 80 simultaneously, consequently can promote the handling efficiency of goods greatly.

The "front" means a forward direction of the box car, and the "rear" means a backward direction of the box car.

It should also be noted that in other embodiments not shown in the figures, the anti-friction structure 30 may also comprise only the multi-directional anti-friction structure 31. The multi-directional friction reducing structure 31 is more expensive to produce than the one-directional friction reducing structure 32. The embodiment of the invention is beneficial to reducing the production cost by simultaneously arranging the one-way antifriction structure 32 and the multi-way antifriction structure 31.

As shown in fig. 1, in the present embodiment, the second floor module 20 between two first floor modules 10 is provided with a logo structure 40. Specifically, when loading goods, the adjacent first floor modules 10 need to stack the container devices 80 on the second floor module 20 between the two first floor modules 10, but when the container devices 80 are placed on the second floor module 20 for the first time, the operator may not easily know where to place the container devices 80, and the number of the container devices 80 stacked on the second floor module 20 from the two first floor modules 10 is equal. In the above-mentioned structure, be provided with sign structure 40 and make operating personnel can find the position of placing of collection dress utensil 80 when piling up collection dress utensil 80 on the second floor module 20 between two first floor modules 10 for the first time to furthest promotes the handling efficiency of goods.

It should be noted that the efficiency of loading and unloading the container 80 can be improved to the maximum extent by equalizing the number of the container 80 in which the two subsequent first floor modules 10 are stacked on the second floor module 20.

It should be noted that, in the case where the total number of the container devices 80 carried on the floor is odd and the floor has a central symmetrical structure, when the first container device 80 is placed on the second floor module 20 between the two first floor modules 10 for the first time, the first container device 80 needs to be placed at the center of the second floor module 20 between the two first floor modules 10. This ensures that the number of container devices 80 subsequently moved from the two first floor modules 10 to the second floor module 20 is equal. When the container 80 is subsequently stacked on the second floor module 20, one container 80 can be placed on each of the two first floor modules 10, and the two container 80 can be pushed onto the second floor module 20 at the same time, so that the two container 80 can be closely adjacent to the placed container 80.

In order to facilitate the operator to find the specific position of the container device 80 placed on the second floor module 20 between the two first floor modules 10 for the first time, as shown in fig. 1, in the present embodiment, the identification structure 40 includes two first identification lines, and the distance between the first identification line and the central line of the second floor module 20 where the first identification line is located is between 575mm and 579 mm. In the above-mentioned structure, when placing collection dress utensil 80, can push away collection dress utensil 80 to two first sign lines in, this kind of mode is convenient for operating personnel to find collection dress utensil 80 specifically place the position to make things convenient for subsequent collection dress utensil 80 to load.

Of course, in other embodiments not shown in the drawings, when the total number of the container devices carried on the floor is even and the floor has a central symmetric structure, when the container devices are placed on the second floor module between two first floor modules for the first time, one container device may be placed on each of the two first floor modules, and the two container devices may be pushed onto the second floor module at the same time so as to be located on both sides of the center line of the second floor module. When subsequently putting the container device on the second floor module, the operation can be repeated, and the container device put on the second floor module by the subsequent codes is close to the container device already placed.

Similarly, in order to facilitate the operator to find the specific position of the packaging device placed on the second floor module between the two first floor modules for the first time, a second identification line may be provided on the second floor module, specifically, the second identification line includes two, and the distance between the second identification line and the center line of the second floor module where the second identification line is located is between 1170mm and 1174 mm. In the structure, when the container appliances are placed, a user can push the two container appliances to the two second identification lines, and the mode is convenient for an operator to find the specific placing positions of the container appliances, so that the subsequent container appliances are convenient to load.

If only the container 80 placed on the second floor module 20 between two first floor modules 10 for the first time is pushed to a predetermined position, the container 80 already placed is likely to be displaced by collision during the loading of the container 80. In order to solve the above problem, as shown in fig. 1, fig. 2, fig. 4 and fig. 5, in this embodiment, the floor further includes one or more first longitudinal limiting structures 50, at least one first longitudinal limiting structure 50 is disposed at the identification structure 40, the first longitudinal limiting structure 50 includes two first limiting surfaces that are oppositely disposed, and normal directions of the two first limiting surfaces are parallel to the preset direction n. In the above structure, after the container 80 has been placed at the predetermined position, the container 80 can be restrained by the first longitudinal restraining structure 50, so that the container 80 located at the predetermined position is prevented from being changed in position.

It should be noted that the above-mentioned "the first longitudinal restraining structure 50 is disposed at the identification structure 40" means that the first longitudinal restraining structure 50 is not disposed on the first identification line, but means that the first longitudinal restraining structure 50 is disposed in the area close to the identification structure 40. The first longitudinal restraint structure 50 enables the identification structure 40 to cooperate to stably restrain the container 80 at a predetermined position.

As shown in fig. 1, 11 and 12, in the present embodiment, the number of the first floor modules 10 is 2, the number of the second floor modules 20 is 3, and the length of the second floor module 20 disposed between two first floor modules 10 in the middle of the floor is twice as long as that of the other first floor modules 10 and that of the other second floor modules 20. Namely, the floor is in a central symmetrical structure. When loading the cargo, one container 80 may be placed on each of the 3 second floor modules 20. The container bodies on the two second floor modules 20 at the end parts are respectively located at one end of the second floor module 20 far away from the central line of the floor. The container 80 on the second floor module 20 between two first floor modules 10 is located at the center of the second floor module 20. After 3 containerization utensil 80 are placed respectively, can place two containerization utensils 80 on first floor module 10, after adjusting the gesture of these two containerization utensils 80, push respectively on two second floor modules 20 adjacent with first floor module 10 towards opposite direction with containerization utensil 80 simultaneously, and make the containerization utensil 80 that places after next-mentioned be close to the containerization utensil 80 that has placed in advance. Similarly, two container devices 80 may be placed on the second first floor module 10, and the two container devices 80 may be stacked in the same manner as the two container devices 80 on the first floor module 10. It should be noted that, in the above structure, two container devices 80 can be simultaneously placed on two first floor modules 10, respectively, and stacking manners of the container devices 80 placed on the two first floor modules 10 are not interfered with each other, so that after the first 3 container devices 80 are placed, 4 container devices 80 can be simultaneously placed on the floor, and the four container devices 80 are simultaneously pushed to the designated positions by 4 operators, thereby completing stacking of goods. The process of unloading the cargo is the reverse process of the above process and is not described herein. By adopting the floor arrangement mode, 4 container devices 80 can be loaded and unloaded simultaneously, so that the loading and unloading efficiency of goods can be further improved.

It should be noted that, in other embodiments not shown in the drawings, n first floor modules 10 are provided, n is an even number greater than 2, n +1 second floor modules 20 are provided, and the length of the second floor module 20 disposed between two first floor modules 10 in the middle of the floor is twice as long as that of the other first floor modules 10 and that of the other second floor modules 20. By adopting the floor arrangement mode, 2n container devices 80 can be loaded and unloaded simultaneously, so that the loading and unloading efficiency of goods can be further improved.

As shown in fig. 1, fig. 2, fig. 4 and fig. 5, in the present embodiment, each of the first floor module 10 and the second floor module 20 includes a plurality of floor modules 1, each of the floor modules 1 further includes a plurality of first longitudinal limiting structures 50, each of the floor modules 1 is provided with a first longitudinal limiting structure 50, each of the first longitudinal limiting structures 50 includes two first limiting surfaces arranged oppositely, and normal directions of the two first limiting surfaces are parallel to the preset direction n. In the above structure, the first longitudinal limiting structure 50 can limit the displacement of the container device 80 in the preset direction n, and prevent the container device 80 from colliding due to the inertia effect when the box wagon is accelerated or braked, thereby causing the damage to the goods in the container device 80. The structure enables each container 80 to be limited by the first longitudinal limiting structure 50, so that the probability of collision of the container 80 due to inertia is reduced.

It should be noted that each floor module 1 includes a metal frame, a hard metal plate, and rubber disposed on an upper surface of the hard metal plate. The wear-resisting effect of rubber is good, and the service life of the floor module 1 can be prolonged. In addition, the floor module 1 has a small area, which is beneficial to forming the first floor module 10 and the second floor module 20 by splicing.

As shown in fig. 1, 2, 4 and 5, in the present embodiment, each floor module 1 is provided with two first longitudinal limiting structures 50, and the two first longitudinal limiting structures 50 are arranged at intervals along a direction m perpendicular to the preset direction n. The structure enables each container 80 to be limited by the two first longitudinal limiting structures 50, so that the container 80 is more stably limited at a preset position, and the collision probability of the container 80 due to the inertia is further reduced.

As shown in fig. 7 and 8, in the present embodiment, the first longitudinal position-limiting structure 50 includes a two-way claw, the two-way claw includes two first hooks 51 hinged to each other and disposed oppositely, two first position-limiting surfaces are respectively disposed on the two corresponding first hooks 51, and the two-way claw includes a first working position protruding from the upper surfaces of the first floor module 10 and the second floor module 20 and a first retracted position lower than the upper surfaces of the first floor module 10 and the second floor module 20. In the above structure, the initial position of the first longitudinal limiting structure 50 is the first recovery position, and after each container device 80 is pushed to the designated position, the bidirectional jaws need to be pressed downwards, so that the bidirectional jaws are moved to the first working position from the first recovery position, and therefore the container devices 80 which have just been placed are limited. The above structure makes the first longitudinal limiting structure 50 not to interfere the movement of the container 80 while having a limiting function.

It should be noted that, in this embodiment, the container devices 80 and the bidirectional jaws are alternately arranged in the preset direction n, that is, two adjacent bidirectional jaws limit one container device 80 in the preset direction n, and the above structure enables each container device 80 to be limited, so as to reduce the probability of collision of the container devices 80 due to the inertia effect.

As shown in fig. 1, 4 and 5, in the present embodiment, the first floor modules 10 and the second floor modules 20 form a main floor 2, and the floor further includes two end plate modules 3 respectively located at two ends of the main floor 2 in the preset direction n; and each end plate module 3 is provided with at least one second longitudinal limiting structure 70, one side of each second longitudinal limiting structure 70, which faces the central line of the main floor 2, is provided with a second limiting surface, and the normal direction of each second limiting surface is parallel to the preset direction n. In the above structure, the second longitudinal limiting structure 70 can reduce the probability that the container device 80 collides with the end cover of the box wagon, thereby reducing the maintenance cost of the box wagon.

As shown in fig. 5 and 6, in the present embodiment, the second longitudinal position-limiting structure 70 includes a one-way claw, the one-way claw includes a second hook 71 protruding from the upper surface of the second floor module 20 and fixedly disposed, and the second position-limiting surface is disposed on the second hook 71. In the above structure, the second hook 71 is fixedly arranged, and when the container has a tendency to move toward the end cover of the box wagon, the second limit surface of the second hook 71 can stop the container, so that the probability that the container collides with the end cover of the box wagon is reduced. The structure is simple, and the production and the processing are convenient.

During operation, the box wagon needs to turn frequently on the one hand and also frequently shakes on the other hand, both of which can move in the direction m or in the opposite direction to the container device 80. If the container 80 is not limited, the container 80 will collide with the side wall or the door of the box car, increasing the maintenance cost of the box car. To solve the above problem, as shown in fig. 1 to 6, in the present embodiment, each of the first floor module 10 and the second floor module 20 includes a plurality of floor modules 1, each of the floor modules 1 further includes a plurality of transverse limiting structures 90, each of the transverse limiting structures 90 is disposed on a direction m perpendicular to the predetermined direction n, each of the transverse limiting structures 90 includes a third limiting surface, the third limiting surfaces of the two transverse limiting structures 90 are opposite, and a normal direction of the third limiting surface is parallel to the direction m. In the above structure, when the container has a tendency to move toward the side wall or the door of the box wagon, the lateral limiting structure 90 may form a stopper for the container, thereby reducing the probability that the container collides with the side wall or the door of the box wagon, and reducing the maintenance cost of the box wagon.

As shown in fig. 2, 3, 9 and 10, in the present embodiment, the plurality of transverse limiting structures 90 include a reversible one-way claw 91 disposed on the first floor module 10, the third limiting surface is disposed on the reversible one-way claw 91, and the reversible one-way claw 91 includes a second working position protruding from the upper surfaces of the first floor module 10 and the second floor module 20 and a second recycling position lower than the upper surfaces of the first floor module 10 and the second floor module 20. In the above structure, the initial position of the turnable one-way claw 91 is the second recovery position, and after the container device 80 on the first floor module 10 is pushed to the specified position, the turnable one-way claw 91 of the container device 80 at both ends of the direction m can be moved to the second working position from the second recovery position, so that the container device 80 is limited. The structure enables the reversible one-way claw 91 to play a limiting role and simultaneously can not cause interference to the movement of the container device 80, thereby being convenient for operators to operate.

As shown in fig. 4 and 5, in the present embodiment, the plurality of lateral position-limiting structures 90 include a plurality of first rollers 92 disposed on the second floor module 20, and a third position-limiting surface is formed on a surface of the plurality of first rollers 92 located on the same side, which is in contact with the container 80. In the above structure, when the container 80 tends to move toward the side wall of the box wagon, the first roller 92 can form a stopper for the container 80, thereby reducing the probability that the container 80 collides with the side wall of the box wagon, and reducing the maintenance cost of the box wagon.
