Technical Field
[0001] The utility model belongs to the technical field of semi-trailers, and in particular relates to a floating limiting device and a container transport vehicle with the device. Background Art
[0002] Container transport semi-trailer can be used to transport container semi-trailer, which has the advantages of fast loading and unloading, and can be directly and conveniently transferred from one means of transport to another means of transport.
[0003] At present, container transport vehicles on the market use locking devices to connect the frame and the container, or use limit blocks to prevent the container from sliding on the frame, but these devices can only connect and limit the movement of the container body on the frame, and cannot prevent the container door from being opened. During the process of transshipment or transportation of containers, the container door may be illegally opened, resulting in the theft or loss of goods in the container, thereby causing property losses. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a floating limit device and a container transport vehicle, which are used to solve the problem that the container on the semi-trailer is easily illegally opened.
[0005] The utility model solves the above technical problems with the following technical solutions: A floating limit device is applied to a vehicle frame, comprising:
[0006] Two track beams are arranged on the main beam of the frame at intervals, and a floating channel is formed in the track beams and passes through the track beams vertically;
[0007] A limiting member is arranged between the two track beams, the limiting member comprises a bearing portion and a limiting portion which form a certain angle, and is respectively used to be limited at the bottom and side of the container, a floating shaft is rotatably connected at the joint of the bearing portion and the limiting portion, 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 is connected to a limit sleeve below the support beam, a sleeve fixing rod passes through the limit sleeve, and the guide member is slidably connected to the through hole of the support beam;
[0009] An elastic member is sleeved on the guide member, the bottom end of the elastic member abuts against the support beam, and the top of the elastic member props up the guide member to lift the limiting member out of the surface of the track beam.
[0010] Compared with the prior art, the above technical solution has the following beneficial effects:
[0011] The floating shaft is limited to move up and down by the floating channel formed on the track beam. The floating shaft is rotatably connected to the limiting piece, and the floating shaft is slidably connected to the support beam and can slide up and down. The elastic piece can lift the floating shaft so that the limiting piece rotatably connected to the floating shaft extends out above the track beam, and the bearing part and the limiting part formed at a certain angle on the limiting part can be stuck on the side of the container, that is, when the bottom of the container is pressed on the bearing part, the limiting part is flipped up and maintained in a roughly vertical state, and the vertical limiting part can prevent the box door on the side of the container from being opened. Only after reaching the destination and lifting the container to separate from the limiting device can the box door be opened, and when the limiting part is tilted, the container is only allowed to slide a small distance on the cargo platform. Therefore, the device also has the function of preventing the container from sliding, and is suitable for short-distance transshipment containers. On the other hand, the limiting piece can float up and down as a whole along the fixed track groove. When a container is loaded directly above the device, the device can be pressed as a whole below the cargo platform inside the frame. The purpose of this design is that the device does not affect the loading of containers of other specifications and ensures the versatility of the transport vehicle.
[0012] Furthermore, it also includes a baffle, which is connected to the outer end of the limiting part and is used to limit the downward movement of the limiting member when the bearing part is attached to the bottom surface of the container.
[0013] Furthermore, a counterweight block is arranged at the outer end of the limiting part, and a limiting beam cooperating with the baffle is arranged at the outer side of the bearing part, so as 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, and when the bearing portion is in contact with the bottom surface of the container, the upper surface of the limiting plate contacts the baffle, and at this time, the downward movement of the limiting member is limited.
[0015] Furthermore, an adjustment plate for adjusting the distance between the floating channels is provided in the floating channel, and a limiting rod located below the floating shaft is connected to the adjustment plate.

[0043] Example 1
[0044] like Figure 1-8 As shown, a floating limiting device provided by the utility model is applied to a vehicle frame, and comprises: two track beams, a limiting member, a guide member and an elastic member.
[0045] Two track beams are arranged at intervals on the main beam of the frame, and a floating channel running through from top to bottom is formed in the track beam. Specifically, the track beam on one side can be arranged at intervals by two square tubes or C-shaped beams, etc., to form a floating channel with a certain width.
[0046] The limiting member is arranged between the two track beams, and the two sides of the limiting member do not interfere with the track beams on both sides, and can move up and down between the two spaced track beams. Specifically, the limiting member includes a bearing part and a limiting part forming a certain angle, which are respectively used to be limited at the bottom and side of the container. The joint of the bearing part and the limiting part is rotatably connected with a floating shaft, and both ends of the floating shaft extend into the floating channel. On the one hand, the floating shaft plays the role of a rotating shaft. When the bottom of the container contacts the bearing part, the limiting part rotates around the floating shaft close to the side of the container to limit the container door on the side of the container. The bearing part and the limiting part form a roughly L-shaped structure. On the other hand, the floating shaft plays the role of driving the limiting member to move up and down. When the bearing part and the limiting part are pressed down as a whole, both ends of the floating shaft are limited in the floating channel, and can drive the limiting member to move down along the floating channel and completely retract into the space between the two track beams.
[0047] The top of the guide member is sleeved on the floating shaft, a support beam is fixed on the main beam, and the support beam is fixed between the two main beams below the floating channel. The bottom of the guide member passes through the through hole on the support beam and is connected to a limiting sleeve below the support beam. The guide member is slidably connected to the through hole of the support beam. The guide member and the floating shaft move in the floating channel to limit the movement of the guide member from the upper and lower directions. The guide member plays a guiding role on the one hand and a supporting role on the other hand. The top of the guide member is rotatably connected to the floating shaft to support the floating shaft and the limiting member. The elastic member is sleeved on the guide member, the bottom end of the elastic member abuts against the support beam, and the top of the elastic member props up the guide member upward to lift the limit member out of the surface of the track beam. Through the cooperation of the elastic member, the elastic member can support the limit member, and the limit sleeve formed by the bottom of the guide member passing through the support beam can limit the upper limit position of the guide member. A sleeve fixing rod passes through the limit sleeve, and the sleeve fixing rod passes through the limit sleeve and the lower part of the guide rod to fix the bottom of the guide rod passing through the support beam and the limit sleeve together. The sleeve fixing rod can be implemented by a screw or the like.
[0048] The floating shaft is limited to move up and down by the floating channel formed on the track beam. The floating shaft is rotatably connected to the limiting piece, and the floating shaft is slidably connected to the support beam and can slide up and down. The elastic piece can lift the floating shaft so that the limiting piece rotatably connected to the floating shaft extends above the track beam, and the bearing part and the limiting part formed at a certain angle on the limiting part can be stuck at the tail of the container, that is, when the bottom of the container is pressed on the bearing part, the limiting part flips up and maintains a roughly vertical state, and the vertical limiting part can prevent the container door from being opened;
[0049] The situation of contact restriction after locking is that the door can only be opened after the destination is reached and the container is lifted and separated from the limit device, and when the limit part is tilted, the container is only allowed to slide a very small distance on the cargo platform. Therefore, the device also has the function of preventing the container from sliding, which is suitable for short-distance transshipment containers. On the other hand, the limiter can float up and down along the fixed track groove as a whole. When the container is loaded directly above the device, the device can be pressed into the frame below the cargo platform as a whole. The purpose of this design is that the device does not affect the loading of containers of other specifications and ensures the versatility of the transport vehicle. Only after the container falls on the frame and the container is just pressed on the load-bearing part, the limit part can automatically flip and press against the door on the side of the container. The side corresponding to the limit part can be any vertical surface of the tail end, front end and side of the container. The limit part is mainly used to limit the door on this surface to prevent the door from being opened. In addition, when the bottom of the container is pressed on the limiting part and the load-bearing part at the same time, the limiting part can be pressed into the frame. When the container adjusts its horizontal position and presses on the load-bearing part, the limiting part can automatically pop up the door restricted to the side of the container, thereby automatically adapting to different containers.
[0050] In this embodiment, the angle formed between the load-bearing portion and the limiting portion is not less than 90°. Since the bottom surface and the side surface of the container are perpendicular to each other, the angle between the limiting portion and the load-bearing portion is limited to be greater than or equal to 90°, which can effectively ensure that when the load-bearing portion is pressed, the limiting portion is effectively turned over and limited to the container door surface;
[0051] The angle between the limiting portion and the bearing portion is set to α, and specifically α can be set to 100°. At this angle, the container door can be effectively prevented from being opened, and at the same time, a certain angle redundancy is provided.
[0052] Another embodiment further comprises a baffle, which is connected to the outer end of the limiting portion and is used to limit the downward movement of the limiting member when the bearing portion is attached to the bottom surface of the container.
[0053] In order to ensure the stability of the limiter when the limit part is limited to the side door of the container, when the limiter floats downward, the baffle plate arranged at the end of the load-bearing part will play a supporting role after being rotated into place, propping up the limiter to prevent the limiter from moving downward as a whole.
[0054] Specifically, to ensure that the limiting function of the baffle can be effectively realized, the baffle does not need to be too long, and a limiting plate is provided below the baffle. When the bearing portion 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.
[0055] A counterweight block is arranged at the outer end of the limiting part, and a limiting beam cooperating with the baffle is arranged 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. At this time, the limiting part is in an initial state.
[0056] By means of the counterweight block and baffle plate arranged at both ends of the limit member, the limit member can be balanced in the initial state, in which the limit part and the load-bearing part are both higher than the upper surface of the track beam, and can automatically adapt to the floating state or the limit state, that is, the container as a whole is pressed on the limit part and the load-bearing part to adapt to the floating state, or the container is pressed on the load-bearing part to automatically adapt to the limit state, wherein the setting of the counterweight block causes the limit member to rotate counterclockwise to the left around the floating axis, and the cooperation of the baffle plate and the limit beam can limit the rotation tendency of the limit member to the target angle.
[0057] At the same time, the setting of the limit plate can prevent the limit part from excessively rotating to the right due to external force interference, resulting in the limit part and the load-bearing part being not in the initial state. When the limit part and the load-bearing part in the limit part are extended, when they rotate clockwise to the right, the baffle plate will interfere with the limit plate, and the limit plate will restrict the limit part from excessively rotating to the right, thereby avoiding the situation where the limit part and the load-bearing part are located below the upper surface of the track beam.
[0058] The floating channel is provided with an adjustment plate for adjusting the spacing of the floating channels, and the adjustment plate is connected with a limit rod located below the floating shaft. The limit rod is not shown in the figure. Specifically, a mounting screw hole is provided at the bottom of the adjustment plate, and the limit rod is installed in the mounting screw hole. The limit rod is located below the floating shaft to prevent the floating shaft from floating downward excessively and to prevent the elastic part from failing. In this state, it is ensured that the limit part can be completely retracted below the upper surface of the track beam.
[0059] The limiting member comprises a top plate and a plurality of reinforcing plates arranged at the bottom of the top plate. The reinforcing plate and the top plate are bent along the middle to form the bearing portion and the limiting portion respectively. The floating shaft passes through the middle of the plurality of reinforcing plates.
[0060] In this embodiment, the guide member includes: a guide rod passing through the support beam, a shaft sleeve and a limit ring.
[0061] The shaft sleeve is arranged on the top of the guide rod and sleeved on the floating shaft. The guide rod is rotatably connected with the floating shaft through the shaft sleeve. A bearing or the like may also be arranged between the shaft sleeve and the floating shaft.
[0062] The limiting ring is arranged on the guide rod and abuts against the top of the elastic member, and the bottom of the elastic member abuts against the top of the support beam. Specifically, the elastic member can adopt a compression spring to lift the guide member as a whole upward so that the limiting member can maintain its initial state.
[0063] The guide member also includes a reinforcing rib, which is arranged at the junction of the outer wall of the shaft sleeve and the guide rod.
[0064] Example 2
[0065] This embodiment also discloses a container transport vehicle, which includes the floating limiting device in embodiment 1.
[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
