[0036] Example 1

[0037] like Figure 1 As shown;

[0038] A railway freight container spreader comprises two bases 1.

[0039] In this embodiment: Since the existing railway freight container slings have poor carrying capacity and durability, and the process of loading and unloading containers is relatively cumbersome, which increases the labor intensity, and the existing railway freight container slings have a relatively single scope of application, and are prone to loosening during the lifting process, causing the goods to fall off the slings, resulting in unnecessary economic losses, and have certain safety hazards, in order to solve this technical problem, a main beam assembly, a connecting assembly and a locking assembly 4 are added on this basis.

[0044] In this embodiment: because a cross frame 21 is provided on the surface of the base 1, and a main board 23 and an auxiliary board 24 are installed between the two cross frames 21, the auxiliary board 24 reinforces the main board 23 through the reinforcing plate 25, the reinforcing rod 1 27 and the reinforcing rod 28, so that the bearing capacity of the main board 23 during hoisting is increased. This design can prevent the main board 23 from breaking or deforming during hoisting.

[0045] It should be noted that the main board 23, the auxiliary board 24, the reinforcing board 25, the reinforcing rod 1 27 and the reinforcing rod 2 28 are all made of stainless steel.

[0046] Going further:

[0047] In an optional embodiment, four triangular plates 22 are centrally and symmetrically fixedly connected to the surface of each cross frame 21 .

This design increases the flexibility of the sling.

[0053] Going further:

[0054] In an optional embodiment, one end of the auxiliary block 34 away from the base plate 35 is fixedly connected to an L-shaped plate 36, one end of the L-shaped plate 36 away from the auxiliary block 34 is fixedly connected to a supporting plate 38, one side of the supporting plate 38 close to the guide plate 31 is fixedly connected to a support rod 39, one end of the support rod 39 away from the supporting plate 38 is fixedly connected to a universal wheel 310, and a slide groove matching the universal wheel 310 is provided on the surface of the guide plate 31.

[0055] In this embodiment: Since an L-shaped plate 36 is provided, the support plate 38 and the support rod 39 on the surface of the L-shaped plate 36 can be used to drive the universal wheel 310 to slide in the slide groove 1 through the support rod 39. The design can reinforce the bottom plate 35 to prevent the bottom plate 35 from falling off.

[0057] In an optional embodiment, the surface of the L-shaped plate 36 is fixedly connected to the limiting block 311 , and the surface of the guide plate 31 is provided with a limiting groove 1 adapted to the limiting block 311 .

[0058] In this embodiment, since the limiting block 311 and the limiting groove are compatible with each other, this design is adopted to further reinforce and limit the bottom plate 35.

[0059] It should be noted that the limit block 311 adopts a line-surface contact method to reduce the friction generated during the movement.

[0060] Going further:

[0061] In an optional embodiment, four vertical plates 313 are symmetrically fixedly connected to a side of the main board 23 away from the auxiliary board 24, and the four vertical plates 313 correspond to each other. A transmission shaft 314 is rotatably connected between two corresponding vertical plates 313, and two sprocket wheels 315 are symmetrically fixedly connected to the surface of the transmission shaft 314. The four sprocket wheels 315 correspond to each other, and chains 316 are meshingly connected to the surfaces of the two corresponding sprocket wheels 315. Both chains 316 are fixedly connected to the bottom plate 35, and a servo motor 317 is installed on a side of one of the vertical plates 313 away from the transmission shaft 314, and the output shaft of the servo motor 317 passes through the vertical plate 313 and is fixedly connected to the transmission shaft 314.

[0062] In this embodiment: because a sprocket 315 and a chain 316 are provided, the servo motor 317 can be started, and the output shaft of the servo motor 317 can rotate to drive the transmission shaft 314 to rotate, and the rotation of the transmission shaft 314 can drive the sprocket 315 to rotate, and the cooperation of the sprocket 315 and the chain 316 can drive the base plate 35 to move. This design can further facilitate the movement of the base plate 35.

[0063] Going further:

[0064] In an optional embodiment, a winch 312 is installed on a side of the bottom plate 35 away from the main plate 23, a hinge seat 37 is arranged below the winch 312, a pull rope of the winch 312 is wrapped around the shaft of the hinge seat 37, a cross plate 318 is arranged below the hinge seat 37, and the hinge seat 37 is fixedly connected to the cross plate 318, four reinforcement frames 319 are fixedly connected to the surface center of the cross plate 318, and the four ends of the cross plate 318 are fixedly connected to the base 320.

[0065] In this embodiment: since a winch 312 is provided on the surface of the bottom plate 35, the hinge seat 37 is pulled by the winch 312, and since the hinge seat 37 is fixed to the cross plate 318, the cross plate 318 is lifted and lowered, and the cross plate 318 is reinforced by providing a reinforcement frame 319.

[0066] Going further:

[0067] In an optional embodiment, each base 320 is fixedly connected to a hook 321 on one side away from the main board 23, a hanging plate 327 is arranged below the cross plate 318, and four sides of the hanging plate 327 are fixedly connected to hanging blocks 323, and each hanging block 323 corresponds to the hook 321 one by one, and a connecting rod 322 is arranged between each corresponding hook 321 and hanging block 323, and they are connected through the connecting rod 322.

[0068] In this embodiment: since a base 320 is provided on the surface of the cross plate 318, a hook 321 is installed through the base 320, and the hook 321, the connecting rod 322 and the lifting block 323 cooperate to drive the lifting plate 327 to move. This design can further facilitate the loading and unloading of containers.

[0069] Going further:

[0070] In an optional embodiment, adjacent surfaces of the cross plate 318 and the hanging plate 327 are fixedly connected with a truncated cone 324, and a spring damper 325 is provided between the two truncated cones 324, and the spring damper 325 is connected to the two truncated cones 324 via a connecting hook and a connecting ring.

[0071] In this embodiment: because the surfaces of the cross plate 318 and the hanging plate 327 are both provided with a truncated cone 324, and a spring damper 325 is provided between the truncated cones 324, this design is adopted to prevent the main beam from breaking due to the excessive weight of the container.

[0072] It should be noted that the spring damper 325 is composed of a cylinder, a piston, oil, a piston rod and a spring. When the spring is compressed, the piston moves downward, the space under the piston becomes smaller, and the oil is squeezed and flows upward. Conversely, the oil flows downward and passes through the valve hole on the piston during the flow of the oil. The oil encounters resistance when passing through the valve hole, slowing down the movement of the piston, and part of the impact force is absorbed and slowed down by the oil.

[0073] Going further:

[0074] In an optional embodiment, it further includes a locking assembly 4 disposed on the surface of the hanging plate 327;

[0075] The locking assembly 4 includes a mounting frame 41 fixedly connected to the surface of the hanging plate 327, a bidirectional screw rod 42 is rotatably connected to the inner side of the mounting frame 41, and a servo motor 43 is installed on the inner side of the mounting frame 41, the output shaft of the servo motor 43 passes through the surface of the mounting frame 41 and is fixedly connected to the bidirectional screw rod 42, two moving blocks 44 are symmetrically threadedly connected to the surface of the bidirectional screw rod 42, and a lifting block 45 is fixedly connected to the surface of each moving block 44, and fixed blocks 46 are fixedly connected to both ends of the mounting frame 41, a guide column 47 is fixedly connected between the two fixed blocks 46, and the guide column 47 is slidably connected to the lifting block 45.

[0076] In this embodiment: since the surface of the lifting plate 327 is provided with a mounting frame 41, when the staff is lifting containers of different sizes, they can start the servo motor 2 43, and the output shaft of the servo motor 2 43 rotates, so that the bidirectional screw rod 42 drives the two moving blocks 44 to move, and the moving block 44 drives the lifting block 45, and when the lifting block 45 moves, it is limited by the guide column 47, and the lifting block 45 is reinforced.

[0077] Going further:

[0078] In an optional embodiment, a lifting rod 48 is provided at the lifting ring of the lifting block 45, and the end of the lifting rod 48 away from the lifting block 45 is connected to a locking hook 49, and the surface of the locking hook 49 is threadedly connected to a threaded rod 410, and the lifting rod 48 is connected to the locking hook 49 through the threaded rod 410, and the surface of the locking hook 49 is rotatably connected to a stopper 411, and the surface of the locking hook 49 is threadedly connected to a bolt 412, and one end of the bolt 412 passes through the stopper 411 and is threadedly connected to a nut 413 arranged on the other side of the locking hook 49.

[0079] In this embodiment: because the locking hook 49 is connected to the bottom of the lifting block 45 through the lifting rod 48, the staff can clamp the hook part of the locking hook 49 on the lifting ring of the container, and through the cooperation of the bolt 412 and the nut 413, the stopper 411 can clamp the lifting ring on the surface of the container to prevent the container from falling off.

[0080] Working principle: Because the surface of the base 1 is provided with a cross frame 21, and a main board 23 and an auxiliary board 24 are installed between the two cross frames 21, the auxiliary board 24 completes the reinforcement of the main board 23 through the reinforcement plate 25, the reinforcement rod 1 27 and the reinforcement rod 2 28, so that the bearing capacity of the main board 23 during hoisting is increased. This design can prevent the main board 23 from breaking or deforming during hoisting. Because the surface of the cross frame 21 is reinforced by the triangle plate 22, this design can further stabilize and reinforce the main beam. Because guide plates 31 are provided on both sides of the main board 23, it can be The cooperation between the slider 33 and the slide rail 32 enables the auxiliary block 34 to drive the bottom plate 35 to move on the surface of the main plate 23. This design increases the flexibility of the hanger. Because an L-shaped plate 36 is provided, the load-bearing plate 38 and the support rod 39 on the surface of the L-shaped plate 36 can be used to drive the universal wheel 310 to slide in the slide groove 1 through the support rod 39. The bottom plate 35 can be reinforced to prevent the bottom plate 35 from falling off. Because the limit block 311 is adapted to the limit groove 1, this design is adopted to further reinforce and limit the bottom plate 35. There are sprockets 315 and chains 316. By starting a servo motor 317, the output shaft of the servo motor 317 rotates to drive the transmission shaft 314, and the transmission shaft 314 rotates to drive the sprocket 315 to rotate. The cooperation of the sprocket 315 and the chain 316 drives the bottom plate 35 to move. This design can further facilitate the movement of the bottom plate 35. Since a winch 312 is provided on the surface of the bottom plate 35, the winch 312 pulls the hinge seat 37. At the same time, since the hinge seat 37 is fixed to the cross plate 318, the cross plate 318 can be lifted and lowered. The reinforcement frame 319 reinforces the cross plate 318. A base 320 is provided on the surface of the cross plate 318, and a hook 321 is installed through the base 320. The hook 321, the connecting rod 322 and the lifting block 323 cooperate to drive the hanging plate 327 to move. This design can further facilitate the loading and unloading of the container. Since the surfaces of the cross plate 318 and the hanging plate 327 are both provided with a round table 324, and a spring damper 325 is provided between the round tables 324, this design can prevent the main beam from breaking due to the excessive weight of the container.
