Description

Technical Field

[0001] This invention relates to the field of transportation equipment technology, and more particularly to a tanker truck for transporting liquids. Background Technology

[0002] Existing tank trucks used for unloading typically use compressed air to purge the liquid from the discharge port. Before the liquid can be discharged, workers need to open the discharge port. However, because the tank is filled with compressed air, the liquid sprays out the moment the port is opened, splashing onto the workers. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the present invention provides a tanker truck for transporting liquids, including a vehicle body and a tank body spaced apart from the vehicle body. The rear end of the vehicle body and the rear end of the tank body are hinged together. A telescopic mechanism for pushing the tank body is provided between the vehicle body and the tank body to allow the tank body to tilt towards the vehicle body. A discharge port is provided on the end face of the rear end of the tank body, and a discharge cover is provided on the discharge port to open and close the discharge port. A long rod is provided on the side of the tank body facing the vehicle body, and one end of the long rod is connected to the... The tank body is hinged, and a locking buckle for locking the discharge cover is provided on the other end of the long rod. A pull rod intersecting the long rod is provided on the long rod. A fixed pulley is provided on the side of the vehicle body facing the tank body. The pull rod and the tank body are connected to each other by a rigid pull rope. At least a part of the rigid pull rope is sleeved on the fixed pulley. When the angle between the tank body and the vehicle body gradually increases, the tank body pulls the pull rod through the rigid pull rope, so that the locking buckle moves away from the discharge cover, thereby releasing the locking effect on the discharge cover.

[0004] Preferably, the pull rod is connected to the rear of the vehicle body by a tension spring. As the angle between the tank and the vehicle body gradually decreases, the tension spring can provide a restoring force to the pull rod to bring the locking buckle closer to the unloading cover, so as to restore the locking effect on the unloading cover.

[0005] Preferably, the unloading cover is provided with a locking clip that matches the locking buckle.

[0006] Preferably, the fixed pulley is provided with an anti-detachment clip to prevent the rigid pull rope from detaching from the fixed pulley.

[0007] Preferably, the hinge axis between the rear of the vehicle body and the rear of the tank is parallel to the hinge axis between the long rod and the tank.

[0008] Preferably, the rigid tension rope is a steel wire rope.

[0009] Compared with existing tank truck unloading methods, the tank truck for transporting liquids of the present invention tilts the tank to the vehicle body during the unloading process through a telescopic mechanism set between the vehicle body and the tank body. This allows the liquid inside the tank to be discharged from the unloading port due to its own weight. At the same time, during the tilting process between the tank body and the vehicle body, the tank body releases the locking effect on the unloading cover through a rigid pull rope connected to it. This eliminates the need for personnel to open the unloading port, thereby preventing the problem of liquid materials splashing onto personnel during unloading. Attached Figure Description

[0012] To make the objectives, technical solutions, and advantages of the present invention clearer, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Examples of these preferred embodiments are illustrated in the drawings. The embodiments of the present invention shown in and described with reference to the drawings are merely exemplary, and the present invention is not limited to these embodiments.

[0013] It should also be noted that, in order to avoid obscuring the invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the invention are shown in the accompanying drawings, while other details that are not closely related to the invention are omitted.

[0014] In view of the problems of the prior art mentioned in the background, the present invention provides the following specific embodiments.

[0015] This embodiment provides a tanker truck for transporting liquids, such as... Figures 1 to 3As shown, the tanker truck of this embodiment includes a vehicle body 1 and a tank body 2 spaced apart from the vehicle body 1. The rear end of the vehicle body 1 and the rear end of the tank body 2 are hinged together. A telescopic mechanism 3 for pushing the tank body 2 is provided between the vehicle body 1 and the tank body 2, so that the tank body 2 can tilt relative to the vehicle body 1. A discharge port 4 is provided on the end face of the rear end of the tank body 2, and a discharge cover 5 for opening and closing the discharge port 4 is provided on the discharge port 4. A long rod 6 is provided on the side of the tank body 2 facing the vehicle body 1, and one end of the long rod 6 is hinged to the tank body 2. The hinge axis between the rear end of the vehicle body 1 and the rear end of the tank body 2 is parallel to the hinge axis between the long rod 6 and the tank body 2. A locking buckle 61 for locking the discharge cover 5 is provided on the other end of the long rod 6. A pull rod 62 is provided on the long rod 6, intersecting with the long rod 6. The pull rod 62 is relatively close to the hinge between the long rod 6 and the tank body 2, and extends towards the vehicle body 1. A fixed pulley 7 is provided on the side of the vehicle body 1 facing the tank body 2. Preferably, there is a predetermined distance between the fixed pulley 7 and the rear of the vehicle body 1. The pull rod 62 and the tank body 2 are connected to each other by a rigid pull rope A. At least a portion of the rigid pull rope A is sleeved on the fixed pulley 7. The fixed pulley 7 is provided with an anti-detachment clip (not shown in the figure) to prevent the rigid pull rope A from detaching from the fixed pulley 7.

[0016] Specifically, the total length of the rigid pull rope A is less than the sum of the maximum distance from the connection point of the rigid pull rope A with the tank body 2 to the fixed pulley 7 and the distance from the free end of the pull rod 62 to the fixed pulley 7.

[0017] like Figure 2 As shown, when the tank 2 tilts relative to the vehicle body 1 under the push of the telescopic mechanism 3, the angle between the tank 2 and the vehicle body 1 gradually increases. During this process, the tank 2 pulls the pull rod 62 through the rigid pull rope A, causing the long rod 6 to shift relative to the tank 2, thereby moving the locking buckle 61 away from the discharge cover 5 and releasing the locking effect on the discharge cover 5.

[0018] Preferably, the pull rod 62 is connected to the rear of the vehicle body 1 by a tension spring 8. As the angle between the tank body 2 and the vehicle body 1 gradually decreases, the tension spring 8 provides a restoring force to the pull rod 62, causing the locking buckle 61 to approach the discharge cover 5, thereby restoring the locking effect on the discharge cover 5. To improve the sealing of the discharge port 4, the discharge cover 5 is provided with a locking clip that matches the locking buckle 61.

[0019] Preferably, in this embodiment, the rigid tension rope A is a steel wire rope.

[0020] Compared with existing tank truck unloading methods, the tank truck used for transporting liquids in this embodiment tilts the tank to the vehicle body during unloading by using a telescopic mechanism between the vehicle body and the tank. This allows the liquid inside the tank to be discharged from the unloading port due to its own weight. At the same time, as the tank tilts, the tank releases the locking effect on the unloading cover through a rigid pull rope connected to it. This eliminates the need for personnel to open the unloading port, thus preventing the liquid from splashing onto the personnel during unloading.

[0021] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
