Description

Technical Field

[0001] This utility model relates to the technical field of cryogenic liquid storage and transportation equipment, specifically to a guide trough anti-collision beam structure for a semi-trailer used for cryogenic liquid transportation. Background Technology

[0002] Cryogenic tank trucks are specialized vehicles designed to transport cryogenic liquefied gases. These tank trucks are typically used to transport industrial gases and energy products such as liquid oxygen, liquid nitrogen, liquid argon, and liquefied natural gas (LNG). Because these goods need to remain liquid at extremely low temperatures, cryogenic tank trucks must have excellent thermal insulation properties to maintain the cryogenic internal environment.

[0003] Cryogenic liquid transport semi-trailers mainly consist of a high-vacuum insulated tank fixed to a non-powered walking mechanism via V-beams. Two outriggers are installed at the bottom of the tank, a valve box is located at the rear, and the towing pin assembly is at the front. The towing device on the tractor unit must be connected to the towing pin to move the semi-trailer. The tractor unit connects to the towing pin in reverse. If the outriggers on the tank are not properly adjusted in height, the towing pin and the tractor unit will be at different heights. When the tractor unit reverses and connects to the tank's towing pin, the rear of the tractor unit may collide with the tank, causing damage to the appearance of the cryogenic liquid transport tank and affecting the tank's vacuum. Severe vacuum loss may pose a safety risk.

[0004] In view of the above, it is necessary to propose a guide channel anti-collision beam structure for semi-trailers used for transporting cryogenic liquids to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to overcome the defects in the existing technology and provide a guide channel anti-collision beam structure for a semi-trailer used for transporting cryogenic liquids.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A guide channel anti-collision beam structure for a semi-trailer used for transporting cryogenic liquids includes a guide web structure and a guide panel structure. The guide web structure is arranged along the length of the tank body and is located on the lower side of the front end of the tank body. The upper edge of the guide web structure forms a curved shape that matches the outer surface of the tank head. The lower edge of the guide web structure is provided with a guide panel structure. The guide web structure is arranged in a vertical direction, and the guide panel structure is arranged perpendicular to the guide web structure, extending from the first end to the last end of the guide web structure. The guide web structure and the guide panel structure form a guide anti-collision rib. The guide channel anti-collision beam structure includes at least two guide anti-collision ribs arranged parallel to each other at the front end of the tank body.

[0007] Furthermore, the guide groove anti-collision beam structure is disposed at the front end of the traction pin assembly. The traction pin assembly includes a traction pin base plate and a traction pin head. The traction pin head is formed by a downward protrusion in the middle of the bottom surface of the traction pin base plate. The lowest point of the bottom surface of the guide panel structure is higher than the plane where the traction pin base plate is located.

[0008] Furthermore, the front end of the guide anti-collision rib forms an upward-curved head, and the rear end forms a sliding support part parallel to the tank axis. The lowest point of the bottom surface of the guide panel structure is lower than the lowest point of the bottom end of the tank head.

[0009] Furthermore, the guide web structure forms a J-shaped plate, which includes a curved plate at the front end and a straight plate at the rear end; the guide panel structure includes an arcuate plate portion and a straight plate portion that cooperate with the lower edge of the guide web structure.

[0010] Furthermore, a reinforcing base plate is provided between the upper edge of the guide web structure and the tank body, the guide web is fixedly welded to the lower side of the reinforcing base plate, and a guide panel structure is fixedly welded to the lower edge of the guide web structure.

[0011] Furthermore, the guide web structure is provided with through holes, and the through holes of the guide anti-collision ribs on both sides are correspondingly arranged. A lateral reinforcing tie rod is pulled between the through holes on both sides. The two ends of the lateral reinforcing tie rod are threaded parts, and two nuts are screwed onto the threaded parts. The two nuts are located on both sides of the guide web structure to form a clamping and fixing.

[0012] Furthermore, the front end of the curved plate of the guide anti-collision ribs on both sides is connected to a transverse base plate, and the front side of the transverse base plate is provided with a front buffer plate spaced by elastic buffer members.

[0013] Furthermore, the elastic cushioning element is one or more of rubber, polyurethane foam, and airbag.

[0014] Furthermore, the elastic buffer includes a spring and a guide mechanism. The spring and guide mechanism are disposed between the transverse base plate and the front buffer plate. The guide mechanism guides the compression and rebound of the spring and makes the front buffer plate move parallel to the transverse base plate.

[0015] The advantages and beneficial effects of this utility model are as follows: This utility model provides a guide groove anti-collision beam structure for a semi-trailer used for transporting cryogenic liquids. A guide groove anti-collision beam is designed at the front end of the towing pin assembly at the bottom of the tank. When the tractor unit is connected to the towing pin, first locate the center of the guide groove anti-collision beam and the position of the towing pin, adjust the direction of the tractor unit, and slowly reverse. The rear of the tractor unit first contacts the guide groove anti-collision beam to avoid direct collision with the front end of the tank. Then, by adjusting the height of the outriggers, the tractor unit's trailer is connected to the towing pin. The guide groove anti-collision beam mainly guides the driver to align with the direction of the tractor's front end, preventing the tractor unit from directly colliding with the tank when connected to the towing pin, thus affecting the product's vacuum performance.

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0024] A structure for a guide channel anti-collision beam for a semi-trailer used in cryogenic liquid transport, such as Figure 1-6As shown, it includes a guide web structure 1 and a guide panel structure 2. The guide web structure 1 is arranged along the length direction of the tank body 3 and is located on the lower side of the front end of the tank body 3. Specifically, as shown... Figure 2 , 5 As shown, it is made of a whole steel plate and cut according to the front shape of the tank body 3, so that the upper edge of the guide web structure 1 forms a curved shape that matches the outer surface of the tank body 3 head; it includes a curved plate 10 at the front end and a straight plate 11 at the rear end, so that the guide web structure 1 formed by the curved plate 10 and the straight plate 11 forms a J-shaped plate.

[0025] A guide panel structure 2 is provided at the lower edge of the guide web structure 1, such as... Figure 4 As shown in the figure, the upper side is a side view of the actual shape of the guide web structure 1 after the bending plate 10 is processed, and the lower side is a blanking diagram of the guide web structure 1 on the steel plate. The guide panel structure 2 includes an arc plate part 12 and a straight plate part 11 that cooperate with the lower edge of the guide web structure 1. In specific processing, after the blanking is completed according to the design dimensions, the arc plate part 12 at the front end is bent into an arc shape that matches the lower edge of the guide web structure 1.

[0026] During specific welding, the guide web structure 1 is arranged vertically, and the guide panel structure 2 is arranged perpendicularly to the guide web structure 1 and welded to the lower edge of the guide web structure 1, forming a shape as shown. Figure 2 The structure shown is modified to enhance the strength of the weld between the guide channel anti-collision beam structure and the tank body 3, as an improvement. Figure 2 As shown, a reinforcing base plate 14 is provided between the upper edge of the guide web structure 1 and the tank body 3. The guide web is fixedly welded to the lower side of the reinforcing base plate 14, and a guide panel structure 2 is fixedly welded to the lower edge of the guide web structure 1. The guide panel structure 2 extends from the first end of the guide web structure 1 to its last end; the guide web structure 1 and the guide panel structure 2 together form a guide anti-collision rib 4. In actual use, the guide groove anti-collision beam structure includes at least two guide anti-collision ribs 4 arranged parallel to each other at the front end of the tank body 3; as... Figure 3 As shown, the structure consists of two sets of guide anti-collision ribs and four sets of cost guide groove anti-collision beams.

[0027] Furthermore, this device is positioned at the front end of the traction pin assembly 5, such as... Figure 1 , 2 As shown, the traction pin assembly 5 includes a traction pin base plate 6 and a traction pin head 7. The traction pin head 7 is formed by a downward protrusion in the middle of the bottom surface of the traction pin base plate 6. The lowest point of the bottom surface of the guide panel structure 2 is higher than the plane where the traction pin base plate 6 is located.

[0028] When connecting the tractor unit to the towing pin, first locate the center of the guide rail anti-collision beam and the position of the towing pin, adjust the direction of the tractor unit, and slowly reverse. The rear of the tractor unit should first contact the guide rail anti-collision beam to avoid direct collision with the front end cap of tank 3. Then, adjust the outrigger height to connect the tractor unit's trailer to the towing pin. The guide rail anti-collision beam mainly guides the driver to align the tractor unit with the front of the vehicle, preventing direct collision between the tractor unit and tank 3 when connecting to the towing pin, which would affect the product's vacuum performance.

[0029] The design of the lowest point of the guide panel structure 2 being higher than the plane of the traction pin base plate 6 prevents the guide groove anti-collision beam structure from affecting the connection between the tractor and the traction pin. Furthermore, the front end of the guide anti-collision rib 4 forms an upward-curved head 8, and the rear end forms a sliding support part 9 parallel to the axis of the tank body 3. The lowest point of the bottom surface of the guide panel structure 2 is lower than the lowest point of the bottom end of the tank body 3's end cap. In actual use, because the lowest point of the tank body 3's end cap is higher than the bottom surface of the guide panel, when the end cap faces a scraping collision from below, the guide panel structure 2 first contacts the obstacle, thus avoiding collision with the surface of the tank body 3 and preventing deformation of the tank body 3.

[0030] The guide web structure 1 is provided with a through hole 15, such as Figure 2 , 5 As shown, the through holes 15 on both sides of the guide anti-collision ribs 4 are positioned correspondingly, and lateral reinforcing rods 16 are strung between the through holes 15 on both sides. The two ends of the lateral reinforcing rods 16 are threaded, and two nuts 17 are screwed onto the threaded portions. The two nuts 17 are located on both sides of the guide web structure 1 to form a clamping fixation. In actual use, as shown in the figure, three through holes 15 are provided, and three reinforcing rods 16 can be strung between the two guide anti-collision ribs 4. Figure 3 The diagram shows a view from the front end of the tank body 3. The threaded ends are inserted into the through holes 15, and the nuts 17 are tightened from the inside and outside respectively, thereby fixing the lateral distance between the two guide anti-collision ribs 4, thus forming lateral reinforcement.

[0031] As an improvement, such as Figure 5As shown, a transverse base plate 18 is connected to the front end of the curved plate 10 of the two side guide anti-collision ribs 4. A front buffer plate 19, spaced apart by elastic buffer members 20, is provided on the front side of the transverse base plate 18. Since there are only two guide anti-collision ribs 4, the frontal collision contact area of ​​the overall structure is small, and anti-collision and guidance can only be performed at the lower part of the end cap. When facing a more frontal collision, not only is the contact area small, but it is also unable to provide good buffering and anti-collision. In this embodiment, a transverse base plate 18 is pulled up at the front end of the curved plate 10 to increase the frontal contact area, and a front buffer plate 19 is provided at the front for contact collision. The elastic buffer member 20 between the two can effectively absorb energy and reduce the impact of the collision on the tank body 3. The elastic buffer member 20 can be one or more of rubber, polyurethane foam, and airbag.

[0032] As an improvement, such as Figure 6 As shown, the elastic buffer 20 includes a spring 21 and a guide mechanism 22. The spring 21 and the guide mechanism 22 are disposed between the transverse base plate 18 and the front buffer plate 19. The guide mechanism 22 guides the compression and rebound of the spring 21 and allows the front buffer plate 19 to move parallel to the transverse base plate 18. In this embodiment, the spring 21 is used for buffering and energy absorption. In this embodiment, the guide mechanism 22 can specifically adopt the following... Figure 6 The scissor mechanism shown.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
