Description

Technical Field

[0001] The utility model relates to the technical field of chemical industry, and more specifically to a LNG automatic unloading and boosting skid device. Background Art

[0002] In the chemical industry, liquid media in tank trucks need to be unloaded into storage tanks using a skid. This is usually done naturally by relying on the pressure differential between the tank truck and the tank. However, as the volume of media in the tank truck decreases, the pressure drops, resulting in a smaller pressure differential and longer unloading times. This requires pressurizing the tank truck to maintain a sufficient pressure differential for unloading. The LNG vaporization skid works by pumping LNG liquid gas into a vaporizer via a liquefied natural gas pump, converting it into gaseous gas through heating, and then transporting it via pipeline to where it is needed. This equipment is fast, reliable, and energy-efficient, and is widely used in LNG storage tanks, LNG filling stations, LNG ships, and other fields.

[0003] A Chinese patent application, CN202321111387.9, discloses an LNG automatic unloading and boosting skid device. This device can pressurize the interior of a tank truck, stabilize the unloading flow rate, reduce unloading time, and improve production efficiency. However, it still has certain issues: the device lacks a movable component at the bottom, making it difficult to move, reducing its flexibility and ease of use. Utility Model Content

[0007] The LNG automatic unloading and boosting skid device comprises a frame and an equipment body, wherein the four corners of the bottom of the frame are fixedly connected with rollers. After the use of the equipment body is finished, the first support plate and the second support plate can be folded up, and the rollers are used to move the equipment body, thereby improving the convenience of use. The inner side of the frame is fixedly connected with a mounting frame, the bottom of the mounting frame is fixedly connected with an electric push rod, the output end of the electric push rod is fixedly connected with a connecting seat, the inner side of the connecting seat is fixedly connected with a movable rod, and both ends of the movable rod are rotatably connected with the first support plate, the side away from the movable rod between the two first support plates is fixedly connected with the first support rod, the outer side of the first support plate is rotatably connected with the second support plate, the outer side of the second support plate is rotatably connected with the connecting plate, the connecting plate is fixedly connected to the frame, and the side away from the connecting plate between the two second support plates is fixedly connected with the second support rod. When the electric push rod is started, it will drive the first support plate to move through the connecting seat and the movable rod, and the first support plate will then drive the second support plate to rotate until the first support rod and the second support rod on the first support plate and the second support plate contact the ground and support the equipment body.

[0008] Preferably, the outside of the first support rod and the second support rod are fixedly connected with a wear-resistant sleeve, which is made of rubber material and is used to protect the first support rod and the second support rod and increase the friction between the two and the ground.

Both ends of the guide rod are fixedly connected to fixed plates, one of the fixed plates is fixedly connected to the frame, and the other fixed plate is fixedly connected to the mounting frame. Under the action of the through hole, the movable rod is limited in cooperation with the guide rod.

[0010] Preferably, the through hole is arranged horizontally to prevent the output shaft of the electric push rod from getting stuck during extension and retraction.

[0011] Preferably, the first support plate and the second support plate have the same size. Under the action of the first support plate and the second support plate, the first support rod and the second support rod are matched to ensure that the device body does not shake.

[0012] Preferably, the first support rod and the second support rod have the same size, mainly the first support rod and the second support rod have the same overall length, which prevents the device body from tipping over after being propped up.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] Starting the electric push rod drives the connecting seat and the movable rod to move in the direction close to the electric push rod, and the movable rod directly drives the first support plate and the first support rod to move, and at the same time drives the second support plate to rotate downward through the first support plate until the first support rod and the second support rod are in contact with the ground and support the device body. At this time, the rollers are away from the ground. After use, the electric push rod is controlled to drive the connecting seat and the movable rod to move in the direction away from the electric push rod to retract the first support plate and the second support plate, and the four rollers at the four corners of the bottom of the frame are used to move the device body, thereby improving the flexibility of the device body when in use.
