Description

Technical Field

[0001] The present invention relates to the field of vehicle fixing structures, and particularly to a vehicle fixing structure for a ro-ro ship of an automobile. Background Art

[0002] A ro-ro ship refers to a "ship" that loads and unloads cargo vehicles in a ro-ro manner through a ramp. The concept of a ro-ro ship originated from military tanks or vehicle landing craft. The world's first ro-ro ship was the "Comet" built in the United States in 1958; there are openings on both sides and the stern of the ship, and there are a total of 5 ramps for vehicles to get on and off the ship. Since then, ro-ro ships have developed rapidly and are now popular in Nordic countries.

[0003] The upper deck of a ro-ro ship is flat and through, there are multiple decks below the upper deck, and the decks are connected by ramps or lifting platforms for easy vehicle passage. The superstructure is located at the bow or stern, the engine room is located below the stern deck, the chimney is located on both sides, and the opening is generally located at the stern. There is a large articulated ramp, and the ramp is generally inclined to the shore at an angle of 35° to 45°. The loading and unloading efficiency of a ro-ro ship is very high, and ro-ro ships are widely used in world car transportation.

[0004] Chinese Patent: A small and medium-sized vehicle tire fixing device for a ro-ro ship, authorization announcement number: CN214776426 U, authorization announcement date: November 19, 2021. The left and right ends and the front and rear ends of the vehicle tires are tightly fixed, making the vehicle tires more firm during transportation and not easy to roll. Moreover, since the distance between the first clamping plate and the second clamping plate can be adjusted, it can fix vehicle tires of different diameters, with low limitations and high practicability. However, when a ro-ro ship carries and transports vehicles, it is adjusted between multiple fixed points in the cabin, and after the vehicle is parked, the vehicle is fixed by installing bolt struts and other structures at the fixed points. Such a fixing method requires manual operation one by one. When fixing a large number of vehicles, the workload will be particularly large, seriously restricting the loading and fixing efficiency. Similarly, it is extremely inconvenient during subsequent unloading. Some fixing methods using simple pads have poor stability, are difficult to meet the actual fixing requirements, and are also prone to accidents. Therefore, a vehicle fixing structure for a ro-ro ship of an automobile is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a vehicle fixing structure for a ro-ro ship of an automobile, which solves the problems of inconvenient loading and unloading, labor-consuming and low efficiency of the existing vehicle fixing structure.

[0006] To achieve the above object, the present invention provides the following technical solution: An automobile fixing structure for a ro-ro ship, comprising a control slide rail, a fixed seat, a connecting seat, and a sleeve. Servo motors are fixedly installed on the inner walls at both ends of the control slide rail, and a lead screw is fixedly connected between the two servo motors. Slide blocks are symmetrically sleeved on the surfaces at both ends of the lead screw by threads. The two sides of the slide blocks extend outside the two sides of the control slide rail and are respectively rotatably connected to rotating rods. Positioning bars are rotatably connected to the rotating rods on the same side on the left and right. A traveling groove is provided on the positioning bar, and transition blocks are fixedly connected to both ends of the traveling groove. Chute grooves are provided on the inner walls on both sides of the traveling groove, and a receiving groove is provided in the middle of the lower inner wall of the traveling groove. Slide ways are provided between each receiving groove and the outer side surface of the positioning bar. Guide rods are fixedly connected to the mutually approaching sides of the two positioning bars, and the guide rods are sleeved in cooperation with the sleeve. An automobile positioning mechanism is provided between the two chute grooves.

[0007] A further improvement of the present invention lies in that: The automobile positioning mechanism includes an electric guide rail, a sliding frame, and a clamping groove. Electric guide rails are fixedly connected to the inner walls of each chute groove, and a sliding frame is slidably arranged in the chute groove. A clamping groove is provided on the sliding frame and is slidably sleeved in cooperation with the electric guide rail. A vertical rod is fixedly connected between the upper and lower inner walls of the sliding frame. A connecting block is sleeved on the vertical rod. A limiting inclined block is fixedly connected between the two connecting blocks on both sides.

[0008] A further improvement of the present invention lies in that: The thread directions on the front and rear ends of the lead screw are oppositely arranged, so that the servo motor can drive the lead screw to rotate.

[0009] A further improvement of the present invention lies in that: Circular grooves are provided on each connecting block. The vertical rod passes through the circular groove and is slidably sleeved in the connecting block. A spring is arranged in the circular groove and is sleeved on the outer side surface of the vertical rod.

[0010] A further improvement of the present invention lies in that: The mutually approaching ends of the guide rods fixedly connected to the two positioning bars are respectively slidably sleeved at both ends of the sleeve on their respective sides.

[0011] A further improvement of the present invention lies in that: Each limiting inclined block is slidably arranged in its respective traveling groove and receiving groove.

[0012] A further improvement of the present invention lies in that: The front and rear inner walls of the receiving groove are inclined and are respectively slidably and fittingly attached to the inclined surfaces of the mutually distant ends of the front and rear limiting inclined blocks.

[0013] A further improvement of the present invention lies in that: The sliding frames slidably arranged in the chute grooves on the inner walls on both sides of the traveling groove are both slidably sleeved with connecting blocks through vertical rods, and a limiting inclined block is fixedly connected between the mutually approaching ends of the two connecting blocks on both sides. The sliding frame can be driven to move by the electric guide rail, so that the sliding frames on the front and rear sides move away from each other.

[0014] A further improvement of the present invention lies in that: a mounting seat is fixedly connected to each of the sliding frames, and the mounting seat passes through the slideway on each side and extends outside the positioning strip, and is slidably arranged in the slideway on each side, facilitating the wheels of the vehicle to be parked in the traveling groove.

[0015] Advantages of the present invention:

[0016] 1. The present invention provides a vehicle fixing structure for a vehicle roll-on / roll-off ship. The servo motor can drive the screw rod to rotate, driving the sliders on the front and rear sides to approach or move away from each other, and driving the rotating rod to rotate, adjusting the distance between the positioning strips on the left and right sides, so as to be applicable to vehicles of different widths.

[0017] 2. The present invention provides a vehicle fixing structure for a vehicle roll-on / roll-off ship. Through the sliding sleeve of the connecting block on the vertical rod of the sliding frame and the arrangement of the spring, the connecting block can drive the limiting inclined block to slide up and down, and the electric guide rail can drive the sliding frame to slide in the chute, and the limiting inclined block slides and fits with the inclined surface at one end of the receiving groove, so as to realize that the electric guide rail can drive the movement of the sliding frame, and the sliding frames on the front and rear sides move away from each other.

[0018] 3. First, drive the limiting inclined block to rise from the receiving groove to the traveling groove, and then move away from each other. In this way, in the storage state, it is convenient for the wheels of the vehicle to be parked in the traveling groove. The limiting inclined block in the receiving groove will not form an obstacle, and when fixing, the wheels are limited by the mutual separation of the limiting inclined blocks. At the same time, the movement of the sliding frame will also drive the movement of the mounting seat. In this way, after the wheels are limited by the limiting inclined blocks, the vehicle can be further tied tightly through the mounting seat according to needs, avoiding the problem that the fixing of each vehicle requires manual labor in the prior art.

[0019] 4. The overall structure setting makes the device have the characteristics of convenient fixing and limiting, flexible and intelligent adjustment, effectively avoiding manual labor, improving efficiency, and stable fixing. Description of the Drawings

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figure 1-6 , the present invention provides a technical solution: an automobile fixing structure for a ro-ro ship, including a control slide rail 1, a fixed seat 2, a connecting seat 3, and a sleeve 4. The front and rear ends of the control slide rail 1 are fixedly connected to the fixed seat 2. Further, bolts can be provided on the fixed seat 2 to firmly install the control slide rail 1 in the cabin. At the same time, the mutually remote ends of the fixed seats 2 on both the front and rear sides are fixedly connected to the sleeve 4 through the connecting seat 3.

[0029] Servo motors 5 are fixedly installed on the inner walls at both ends of the control slide rail 1. A lead screw 6 is fixedly connected between the two servo motors 5. Sliders 7 are symmetrically thread sleeved on the surfaces at both ends of the lead screw 6. The two sides of the slider 7 extend to the two outer sides of the control slide rail 1 and are respectively rotatably connected to a rotating rod 8. The rotating rods 8 on the same side on the left and right are rotatably connected to a positioning strip 9. The thread directions on the surfaces of the front and rear ends of the lead screw 6 are oppositely arranged, so that the servo motor can drive the lead screw 6 to rotate, drive the sliders 7 on the front and rear sides to approach or move away from each other, drive the rotating rod 8 to rotate, and adjust the distance between the positioning strips 9 on the left and right sides to facilitate the adaptation and matching of automobiles with different widths.

[0030] One end of each of the guide rods 15 fixedly connected to the positioning bars 9 on both sides is slidably sleeved at both ends of the sleeve 4 on its respective side. When adjusting the distance between the positioning bars 9 on both sides to accommodate vehicles of different widths, the sliding sleeve between the guide rods 15 fixedly connected to the positioning bars 9 and the sleeve 4 can effectively guide the stable multi-distance adjustment process, improving the stability of the adjustment process.

[0031] A travel groove 10 is formed in the positioning bar 9. Transition blocks 11 are fixedly connected to both ends of the travel groove 10. Slide grooves 12 are formed in both inner walls of the travel groove 10. A storage groove 13 is formed in the center of the lower inner wall of the travel groove 10. A slideway 14 is formed between each storage groove 13 and the outer side surface of the positioning bar 9. Guide rods 15 are fixedly connected to the mutually adjacent sides of the two positioning bars 9. The guide rods 15 are cooperatively sleeved with the sleeves 4. An automobile positioning mechanism is arranged between the two slide grooves 12.

[0032] The automobile positioning mechanism includes an electric guide rail 16, a sliding frame 17, and a clamping groove 18. The electric guide rail 16 is fixedly connected to the inner wall of each slide groove 12. A sliding frame 17 is slidably arranged in the slide groove 12. The sliding frame 17 is provided with a clamping groove 18 and is cooperatively slidably sleeved with the electric guide rail 16. A vertical rod 19 is fixedly connected between the upper and lower inner walls of the sliding frame 17. A connecting block 20 is sleeved on the vertical rod 19. A limiting inclined block 23 is fixedly connected between the two connecting blocks 20 on both sides, so that the sliding frame 17 can be driven by the electric guide rail to slide in the slide groove 12, and the limiting inclined block 23 is slidably attached to the inclined surface at one end of the storage groove 13, thereby realizing that the sliding frame 17 can be driven by the electric guide rail 16 to move, and the sliding frames 17 on the front and rear sides move away from each other.

[0033] A circular groove 21 is formed in each connecting block 20. The vertical rod 19 passes through the circular groove 21 and is slidably sleeved in the connecting block 20. A spring 22 is arranged in the circular groove 21. The spring 22 is sleeved on the outer side surface of the vertical rod 19. In this way, under the action of the spring 22 and gravity, the connecting block 20 and the limiting inclined block 23 will both tend to slide downward, and when sliding to the position of the storage groove 13, they will automatically fall into the storage groove 13.

[0034] The sliding frames 17 slidably arranged in the slide grooves 12 on both inner walls of the travel groove 10 are both slidably sleeved with connecting blocks 20 through the vertical rods 19, and the limiting inclined blocks 23 are fixedly connected between the mutually adjacent ends of the two connecting blocks 20 on both sides.

[0035] Each of the limiting inclined blocks 23 is slidably arranged in its respective travel groove 10 and storage groove 13. The inner walls at the front and rear ends of the storage groove 13 are inclined and are respectively in sliding fit with the inclined surfaces at the mutually remote ends of the limiting inclined blocks 23 on the front and rear sides. Thus, when the sliding frame 17 drives the connecting block 20 to slide, it will synchronously drive the limiting inclined blocks 23 to abut against the inclined surfaces of the storage groove 13, causing the limiting inclined blocks 23 to rise from the storage groove into the travel groove 10 and then move away from each other.

[0036] Each sliding frame 17 is fixedly connected with a mounting seat 24. The mounting seat 24 passes through the slideway 14 on its respective side and extends outside the positioning strip 9, and is slidably arranged in the slideway 14 on its respective side, facilitating the parking of the wheels of the vehicle in the travel groove 10. When the limiting inclined blocks 23 are in the storage groove 13, they will not form an obstruction. When fixing, the wheels are limited by the mutual separation of the limiting inclined blocks 23. At the same time, the movement of the sliding frame will also drive the movement of the mounting seat 24. In this way, after the wheels are limited by the limiting inclined blocks 23, the vehicle can be further tied tightly through the mounting seat 24 as needed, thus avoiding the problem that the fixation of each existing vehicle requires manual operation.
