Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for loading and unloading cargo baffles in the rear compartment of trucks, and specifically relates to a safety device for unloading cargo baffles of trailer trucks. Background Technology

[0002] The trailer is equipped with a baffle to facilitate loading and unloading.

[0003] The principles for loading and unloading cargo on trailer trucks are as follows:

[0004] The truck can only be started when the baffle is closed; the baffle can only be opened when the truck is turned off, and loading and unloading can only be carried out when the baffle is open.

[0005] Basic working principle of the baffle:

[0006] The baffle is closed or opened by an electric push rod, which is controlled by a remote control. An electronic trigger is installed in the extension direction of the electric push rod. The position of the electronic trigger determines whether the baffle is closed or opened, and further controls whether the vehicle can be started or loaded / unloaded.

[0007] Existing problems:

[0008] The high failure rate of electronic triggers causes the control logic based on "the electronic trigger determining whether the baffle is closed or open in place, thereby controlling whether the vehicle can be started or loaded / unloaded" to fail.

[0009] There were instances where the baffle was not closed, and the truck driver started the engine in violation of regulations / misoperation; and the truck was not turned off, and the driver opened the baffle to load or unload goods in violation of regulations / misoperation. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0039] Combination Figures 1-4 As shown, this utility model provides a safety device for a cargo unloading baffle on a trailer truck, including a first rotating rod 11 rotatably connected to the trailer body 40. A support block 12 for supporting the baffle 20 is provided on the first rotating rod 11, and a handle 13 is provided on the first rotating rod 11 near the left side wall of the trailer body 40. Operating the handle 13 causes the first rotating rod 11 to rotate, thereby allowing the support block 12 to support the baffle 20 installed on the trailer body 40.

[0040] The support block 12 is provided with rotating mounting seats 14 on both sides, which are connected to the carriage 40. The first rotating rod 11 is rotatably connected to the rotating mounting seats 14.

[0041] A safety device for a trailer truck unloading baffle also includes a locking device 10 for unlocking or locking a first rotating rod 11. The locking device 10 is disposed on the trailer body 40 and includes a housing 102, a lock 107 connected to the housing 102, and a lock disc 103 disposed within the housing 102. The first rotating rod 11 passes through the housing 102 of the locking device 10 and is connected to a handle 13.

[0042] Lock 107 adopts a blade lock with the same structure as the existing technology CN110185322B blade lock. Its lock tongue located in the housing 102 can rotate in the left and right directions. The first rotating rod 11 is provided with a lock disc 103 that matches the lock tongue. The lock disc 103 is located on one side of the lock tongue.

[0043] The locking disc 103 includes a fixed disc 104 connected to the carriage 40 and a rotating disc 105 connected to the first rotating rod 11. The rotating disc 105 is located between the two fixed discs 104. The rotation of the first rotating rod 11 can drive the rotating disc 105 to rotate synchronously. The fixed discs 104 are rotatably connected to the first rotating rod 11, and the first rotating rod 11 can rotate within the fixed discs 104.

[0044] The top of the fixed disk 104 has a slot 106, and the rotating disk 105 has a slot 106.

[0045] Lock 107 is provided with keyhole 101, and the safety key matched with keyhole 101 is fixed to the truck key.

[0046] After turning off the engine and removing the truck key, the safety key can be used to unlock the locking device 10 before operating the handle 13. Turning the handle 13 downwards will cause the first rotating rod 11 to rotate, so that the support block 12 moves away from the baffle 20. After the support block 12 is attached to the cargo box 40, the baffle 20 can be lowered. At this time, the baffle 20 is open and the truck is in the unloading state.

[0047] Push the handle 13 up, the baffle 20 stands upright, and the support block 12 abuts against the baffle 20. At this time, the baffle 20 is in the closed state, and the truck is in the loaded state. Only then can the locking device 10 be locked by the safety key, the first rotating rod 11 be braked, the safety key be removed, and the truck be started.

[0048] The following are the specific unlocking and locking principles:

[0049] When the baffle 20 needs to be closed, push the handle 13 up. At this time, the slot 106 on the rotating disk 105 faces upward, which is consistent with the orientation of the slots 106 on the two fixed disks 104. The three slots 106 form a locking tongue slot. Turn the safety key so that the locking tongue rotates to the side and locks into the locking tongue slot, locking the slot 106 of the rotating disk 105. At this time, the first rotating rod 11 cannot rotate, so the support block 12 cannot move, and the baffle 20 is braked.

[0050] When unloading is required, turn the safety key to move the latch upward and away from the latch groove, and the rotating disk 105 is unlocked; at this time, the handle 13 can be operated so that the first rotating rod 11 can rotate, so that the slot 106 on the rotating disk 105 is not aligned with the slot 106 of the two fixed disks 104, and then the support block 12 moves away from the baffle 20, and the baffle 20 is opened.

[0051] Two baffles 20 are connected to the second rotating rod 23, which is rotatably mounted on the carriage 40 via the mounting base 21.

[0052] One end of the second rotating rod 23 is connected to an electric push rod 24. Controlling the electric push rod 24 to reciprocate can drive the second rotating rod 23 to rotate in both directions, so that the baffle 20 is closed or open.

[0053] A first electronic trigger 22 is located near the electric push rod 24.

[0054] The baffle 20, the second rotating rod 23, the electric push rod 24, and the first electronic trigger 22 are all covered in the background section. When the first electronic trigger 22 fails, the control logic based on "the electronic trigger determining whether the baffle is closed or open to control whether the vehicle can be started or loaded / unloaded" will fail. This can lead to problems such as the truck driver starting the engine illegally / misoperatingly if the baffle is not closed, and the driver opening the baffle to load / unload cargo illegally / misoperatingly if the truck is not turned off.

[0055] For multi-layered truck bodies 40, a cargo unloading baffle safety device for a trailer truck further includes a first connecting rod 30 and a second connecting rod 31.

[0056] The description is based on two layers, each layer having multiple baffles 20.

[0057] Each layer's first baffle 20 is equipped with a support block 12, or each baffle 20 can be equipped with a support block 12.

[0058] The first rotating rod 11 of the first layer is also integrally connected to an L-shaped connecting block, which is connected to a first connecting rod 30 and a second connecting rod 31.

[0059] On the second layer of the carriage 40, a first rotating rod 11, a support block 12, and an L-shaped connecting block 32 are also provided, and the connection relationship between the first rotating rod 11, the support block 12, and the L-shaped connecting block 32 on the second layer is consistent with that on the first layer.

[0060] The first connecting rod 30 and the second connecting rod 31 extend from the L-shaped connecting block 32 of the first layer to be rotatably connected to the L-shaped connecting block 32 of the second layer.

[0061] When the handle 13 of the first layer is operated, the first connecting rod 30 and the second connecting rod 31 can drive the first rotating rod 11 of the second layer to rotate, thereby causing the support block 12 of that layer to be in a supported state or a non-supported state.

[0062] A second electronic trigger (not shown in the figure) is installed on the first-level carriage 40. The second electronic trigger is located behind the first connecting rod 30 and the second connecting rod 31.

[0063] A second electronic trigger is provided to prevent the driver from accidentally pressing the remote control of the electric push rod 24 and opening the baffle 20 without lowering the support block 12, which would damage the entire unloading baffle safety device of the trailer truck.

[0064] When the support block 12 is in the supported state, the first connecting rod 30 and the second connecting rod 31 press down on the second electronic trigger. At this time, the second electronic trigger outputs a shielding signal, which can shield the operation signal of the remote control of the electric push rod 24. Only when the support block 12 is in the unsupported state and the second electronic trigger is not pressed down can the remote control normally control the electric push rod 24 to open the baffle 20.

[0065] The above technical features constitute the preferred embodiment of this utility model, which has strong adaptability and optimal implementation effect. Non-essential technical features can be added or removed according to actual needs to meet the needs of different situations.

[0066] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
