Abstract
Description
Technical Field
[0001] This invention belongs to the field of semi-trailer technology, specifically relating to a floating limit device and a container transport vehicle equipped with such a device. Background Technology
[0002] A container semi-trailer can transport container semi-trailers. It has the advantages of being able to load and unload quickly and to be easily transferred from one mode of transport to another.
[0003] Currently, container trucks on the market use locking devices to connect the chassis and the container, or limit blocks to prevent the container from sliding on the chassis. However, these devices only serve to connect, fix, and restrict the movement of the container on the chassis; they cannot prevent the container doors from being opened. During transshipment or transportation, container doors may be illegally opened, leading to theft or loss of goods inside the container, resulting in property damage. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a floating limit device and a container transport vehicle to solve the problem that containers on semi-trailers are easily opened illegally.
[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A floating limiting device, applied to a vehicle frame, comprising:
[0006] Two track beams are spaced apart on the main beam of the vehicle frame, and a floating channel is formed in the track beams that runs vertically through them;
[0007] A limiting component is disposed between the two track beams. The limiting component includes a bearing part and a limiting part forming a certain angle, which are used to limit the container to the bottom and side surfaces, respectively. A floating shaft is rotatably connected to the joint of the bearing part and the limiting part, and both ends of the floating shaft extend into the floating channel.
[0008] A guide member, the top of which is sleeved on the floating shaft, a support beam is fixed on the main beam, the bottom of the guide member passes through the through hole on the support beam and a limit sleeve is connected below the support beam, and the guide member is slidably connected in the through hole of the support beam;
[0009] An elastic element is sleeved on the guide element, with its bottom end abutting against the support beam and its top supporting the guide element upward to lift the limiting element out of the surface of the track beam.
[0010] Compared with existing technologies, the above technical solutions have the following beneficial effects:
[0011] The floating shaft is restricted to vertical movement via a floating channel formed on the track beam. A limiting component is rotatably connected to the floating shaft, while the floating shaft is slidably connected to the support beam, allowing it to slide up and down. An elastic component can lift the floating shaft, causing the limiting component rotatably connected to it to extend above the track beam. The bearing portion and limiting portion on the limiting component, forming a certain angle, can engage with the side of the container. When the bottom of the container is pressed against the bearing portion, the limiting portion flips up to maintain a roughly vertical position. This vertical limiting portion prevents the container door from being opened. The door can only be opened after the container is lifted and detached from the limiting device upon reaching its destination. Furthermore, when the limiting portion is raised, the container is only allowed to slide a very small distance on the loading platform. Therefore, this device also prevents container slippage and is suitable for short-distance container transfers. On the other hand, the limiting component can float vertically along the fixed track groove. When a container is loaded directly above the device, the device can be pressed entirely into the vehicle frame below the loading platform. This design ensures that the device does not interfere with loading other container sizes, guaranteeing the versatility of the transport vehicle.
[0012] Furthermore, it also includes a baffle connected to the outer end of the limiting part, which is used to restrict the downward movement of the limiting member when the bearing part is attached to the bottom surface of the container.
[0013] Furthermore, a counterweight is provided at the outer end of the limiting part, and a limiting beam that cooperates with the baffle is provided on the outer side of the bearing part, which is used to balance the limiting part and the bearing part at an angle extending above the track beam.
[0014] Furthermore, a limiting plate is provided below the baffle. When the bearing part is in contact with the bottom surface of the container, the upper surface of the limiting plate contacts the baffle, and the downward movement of the limiting member is restricted at this time.
[0015] Furthermore, the floating channel is provided with an adjustment plate for adjusting the spacing of the floating channel, and a limiting rod located below the floating shaft is connected to the adjustment plate.
[0016] Furthermore, the included angle between the bearing portion and the limiting portion is not less than 90°.
[0017] Furthermore, the limiting member includes a top plate and several reinforcing plates disposed at the bottom of the top plate. The reinforcing plates and the top plate are bent along the middle to form the bearing part and the limiting part, respectively. The floating shaft passes through the middle of the several reinforcing plates.
[0018] Furthermore, the guide member includes: a guide rod that passes through the support beam;
[0019] A bushing is disposed at the top of the guide rod and sleeved on the floating shaft;
[0020] A limiting ring is disposed on the guide rod and abuts against the top of the elastic element.
[0021] Furthermore, the guide member also includes a reinforcing rib, which is disposed at the junction of the outer wall of the bushing and the guide rod.
[0022] The present invention also discloses a container transport vehicle, which includes the above-mentioned floating limiting device. Attached Figure Description

[0044] Example 1
[0045] like Figure 1-8 As shown, the floating limiting device provided by the present invention is applied to a vehicle frame and includes: two track beams, a limiting component, a guide component, and an elastic component.
[0046] Two track beams are spaced apart on the main beam of the vehicle frame, and a floating channel is formed in the track beams. Specifically, the track beams on one side can be two square tubes or C-shaped beams spaced apart, forming a floating channel of a certain width between them.
[0047] The limiting component is disposed between the two track beams. The limiting component does not interfere with the track beams on both sides and can move up and down between the two spaced track beams. Specifically, the limiting component includes a bearing part and a limiting part forming a certain angle, which are used to limit the bottom and side surfaces of the container, respectively. A floating shaft is rotatably connected at the joint of the bearing part and the limiting part. The two ends of the floating shaft extend into the floating channel. The floating shaft acts as a pivot. When the bottom of the container contacts the bearing part, the limiting part rotates around the floating shaft and moves closer to the side of the container to limit the door on the side of the container. The bearing part and the limiting part form an approximately L-shaped structure. On the other hand, the floating shaft drives the limiting component to move up and down. When the bearing part and the limiting part are pressed down as a whole, the two ends of the floating shaft are limited in the floating channel and can drive the limiting component to move down along the floating channel and completely retract into the space between the two track beams.
[0048] The top of the guide member is sleeved on the floating shaft. A support beam is fixed on the main beam, positioned between the two main beams below the floating channel. The bottom of the guide member passes through a through hole in the support beam, and a limit sleeve is connected below the support beam. The guide member is slidably connected in the through hole of the support beam. The guide member and the floating shaft move within the floating channel, and the guide member's movement is restricted from both vertical and horizontal directions. The guide member serves both a guiding and supporting function. The top of the guide member is rotatably connected to the floating shaft, supporting the floating shaft and the limit sleeve. An elastic element is sleeved on the guide member, with its bottom end abutting against the support beam and its top supporting the guide member upwards to lift the limiting member out of the track beam surface. Through the cooperation of the elastic element, the elastic element can support the limiting member, while the limiting sleeve formed by the bottom of the guide member passing through the support beam can limit the extreme position of the guide member's upward movement. A sleeve fixing rod passes through the limiting sleeve and the lower part of the guide rod, fixing the bottom of the guide rod passing through the support beam and the limiting sleeve together. The sleeve fixing rod can be implemented by a screw or the like.
[0049] The floating shaft is restricted to moving only up and down by the floating channel formed on the track beam. The floating shaft is rotatably connected to a limiting component, while the floating shaft is slidably connected to the support beam and can slide up and down. The elastic component can lift the floating shaft, so that the limiting component rotatably connected to the floating shaft extends above the track beam. The bearing part and the limiting part forming a certain angle on the limiting part can be locked at the rear of the container. That is, when the bottom of the container is pressed against the bearing part, the limiting part flips up and maintains a roughly vertical state. The vertical limiting part can prevent the container door from being opened.
[0050] When the locking mechanism is engaged, the container door can only be opened after the container is lifted and detached from the limiting device upon reaching the destination. Furthermore, when the limiting part is raised, the container is only allowed to slide a very small distance on the loading platform. Therefore, this device also prevents container slippage and is suitable for short-distance container transfers. On the other hand, the limiting component can float up and down along a fixed track. When a container is loaded directly above the device, it can be pressed entirely into the chassis below the loading platform. This design ensures that the device does not interfere with loading other container sizes, maintaining the versatility of the transport vehicle. Only after the container is placed on the chassis and just rests on the load-bearing part can the limiting part automatically flip and abut against the container's side door. The side corresponding to the limiting part can be any vertical surface of the container—the rear, front, or side. The limiting part primarily restricts the container door on that surface, preventing it from being opened. In addition, when the bottom of the container is pressed on both the limiting part and the load-bearing part, the limiting part can be pressed into the frame. After the container is adjusted to a horizontal position and pressed on the load-bearing part, the limiting part can automatically pop up to restrict the container door on the side of the container, thus automatically adapting to different containers.
[0051] In this embodiment, the included angle between the bearing part and the limiting part is not less than 90°. Since the bottom surface and the side surface of the container are perpendicular to each other, the included angle between the limiting part and the bearing part is limited to greater than or equal to 90°, which can effectively ensure that when the bearing part is pressed, the limiting part can effectively flip and limit the container door surface.
[0052] The included angle between the limiting part and the bearing part is set as α, which can be set to 100°. This angle can effectively prevent the container door from being opened, while also providing a certain degree of angular redundancy.
[0053] Another embodiment further includes a baffle connected to the outer end of the limiting part, used to restrict the downward movement of the limiting member when the bearing part is in contact with the bottom surface of the container.
[0054] To ensure the stability of the limiting component when it is restrained by the side door of the container, when the limiting component floats downward, the baffle at the end of the bearing part will provide support after rotating into place, lifting the limiting component upward and preventing the limiting component from moving downward as a whole.
[0055] Specifically, to ensure that the limiting function of the baffle can be effectively realized, the baffle does not need to be too long. A limiting plate is provided below the baffle. When the bearing part is in contact with the bottom surface of the container, the upper surface of the limiting plate contacts the baffle, and the downward movement of the limiting member will be restricted.
[0056] A counterweight is provided at the outer end of the limiting part, and a limiting beam that cooperates with the baffle is provided on the outer side of the bearing part. This beam is used to balance the limiting part and the bearing part at an angle extending above the track beam. At this time, the limiting part is in its initial state.
[0057] By setting counterweights and baffles at both ends of the limiting component, the limiting component can be balanced in the initial state. In this state, both the limiting part and the bearing part are higher than the upper surface of the track beam, and can automatically adapt to the floating state or the limiting state. That is, the container as a whole is pressed on the limiting part and the bearing part to adapt to the floating state, or the container is pressed on the bearing part to automatically adapt to the limiting state. The setting of the counterweights will rotate the limiting component counterclockwise to the left around the floating axis. The cooperation between the baffle and the limiting beam can limit the rotation trend of the limiting component to the target angle.
[0058] Meanwhile, the setting of the limiting plate can prevent the limiting part from rotating excessively to the right due to external force interference, which would cause the limiting part and the bearing part to be out of the initial state. When the limiting part and the bearing part in the limiting part are extended, when rotating clockwise to the right, the baffle will interfere with the limiting plate. The limiting plate restricts the limiting part from rotating excessively to the right, thus preventing the limiting part and the bearing part from being located below the upper surface of the track beam.
[0059] The floating channel is provided with an adjustment plate for adjusting the spacing of the floating channel. A limiting rod located below the floating shaft is connected to the adjustment plate. The limiting rod is not shown in the figure. Specifically, a mounting screw hole is provided at the bottom of the adjustment plate. The limiting rod is inserted into the mounting screw hole. The limiting rod is located below the floating shaft, which can prevent the floating shaft from floating too far downward and also prevent the elastic element from failing. In this state, it ensures that the limiting element can be completely retracted below the upper surface of the track beam.
[0060] The limiting member includes a top plate and several reinforcing plates disposed at the bottom of the top plate. The reinforcing plates and the top plate are bent along the middle to form the bearing part and the limiting part, respectively. The floating shaft passes through the middle of the several reinforcing plates.
[0061] In this embodiment, the guide component includes: a guide rod, a bushing, and a limiting ring that pass through the support beam.
[0062] A bushing is disposed at the top of the guide rod and sleeved on the floating shaft. The guide rod is rotatably connected to the floating shaft through the bushing. A bearing or the like may also be disposed between the bushing and the floating shaft.
[0063] The limiting ring is disposed on the guide rod and abuts against the top of the elastic element. The bottom end of the elastic element abuts against the top of the support beam. Specifically, the elastic element can be a compression spring, which lifts the guide element upward as a whole, so that the limiting element can maintain its initial state.
[0064] The guide component also includes a reinforcing rib, which is disposed at the junction of the outer wall of the bushing and the guide rod.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
