Description

Technical Field

[0001] The invention belongs to the technical field of semi-trailers, in particular to a transversely movable supporting base device and a vehicle. Background Art

[0002] Special vehicles, as a type of vehicle on a par with commercial vehicles, have always played an important role in the transportation industry. Special trailers are the main force among special vehicles. They have the characteristics of large load area, large load capacity, and flexible transportation, making them very suitable for the transportation of large objects that cannot be disassembled.

[0003] A special trailer is a vehicle used to undertake special transportation tasks or special operations or other special purposes. It has a special compartment and accessories and is only used to transport a certain type of goods or a certain form of goods. Strong speciality: Special trailers are usually designed for specific goods or transportation needs, so they are highly special; Special structure: In order to meet the transportation needs of specific goods, the compartment and accessories of special trailers are usually made of special materials and structural designs; Efficient and convenient: Special trailers can significantly improve the efficiency and convenience of logistics transportation and reduce transportation costs and risks.

[0004] However, since special trailers are usually larger and heavier than ordinary trailers, they are often difficult to move, and lateral displacement is even more difficult, requiring high driving skills and making it difficult to achieve precise displacement. Therefore, there is a lack of an auxiliary mechanism that can effectively reduce the labor intensity of the driver and improve the success rate of operation. Summary of the invention

[0005] In order to solve the problem that a special trailer is difficult to operate during lateral movement, the present invention provides a lateral movable support base device and a vehicle.

[0006] The present invention is achieved through the following technical solutions: A laterally movable support base device comprises a support base body and an outrigger oil cylinder, wherein the outrigger oil cylinders are respectively vertically supported at two ends of the support base body, and the outrigger oil cylinders perform a top extension movement to lift the tires of a vehicle off the ground; The support base body can drive the vehicle chassis to move laterally through the outrigger cylinder; The supporting base body comprises a slideway, a movable base and a transverse moving oil cylinder; the movable base can move along the slideway through the transverse moving oil cylinder; The interior of the movable base is a hollow frame structure, and a reinforcing longitudinal beam and a reinforcing cross beam are respectively provided at both ends of the frame; the reinforcing longitudinal beam is perpendicular to the moving direction of the movable base along the slide; the reinforcing cross beam is parallel to the moving direction of the movable base, and the two side surfaces of the reinforcing cross beam are respectively connected to the frame through a plurality of reinforcing small longitudinal beams, and the reinforcing small longitudinal beams are parallel to the reinforcing longitudinal beams.

[0007] The two ends of the supporting base body are respectively connected to the vehicle body through the outrigger cylinders. After the wheels supporting the vehicle body leave the ground, the lateral movement cylinder is used to realize the movement of the mobile base relative to the slide, thereby pushing the vehicle body to complete the lateral movement. This can achieve precise lateral displacement and reduce the operating difficulty of the driving operator; the encrypted structure at both ends of the mobile base frame can help to increase the higher bearing capacity of the outrigger cylinders and improve the stability during the movement.

[0008] A further improvement of the present invention is that the middle section of the movable base frame is evenly distributed with the reinforcing longitudinal beams.

[0009] A further improvement of the present invention is that a neutral plate is provided in the middle section of the mobile base frame, the neutral plate is parallel to the moving direction of the mobile base, and both ends of the neutral plate are connected between adjacent reinforcing longitudinal beams, which helps to improve the overall structural strength of the mobile base through the reinforcing longitudinal beams and the neutral plate in the middle section of the frame.

[0010] A further improvement of the present invention is that the upper top surface and the lower bottom surface of the frame of the above-mentioned mobile base are respectively covered with a middle cover plate and an edge cover plate, the middle cover plate corresponds to the middle section of the frame of the mobile base, and the edge cover plate corresponds to the end of the frame of the mobile base. The combination of the middle cover plate and the edge cover plate reduces the cost and operation difficulty of processing the entire piece of material, and can correspond to the middle section and the end of the frame respectively, which is helpful for subsequent maintenance.

[0011] A further improvement of the present invention is that the slide includes a slide bottom plate, a slide vertical plate and a slide upper plate, the slide bottom plate is provided with the slide vertical plates on both sides corresponding to the moving direction of the mobile base, and the upper edge of the slide vertical plate is connected to the slide upper plate horizontally arranged above the slide bottom plate. The slide is in a U-shaped structure as a whole, and the upper edge is provided with an inward side, which helps to form a better guide support for the mobile base.

[0012] A further improvement of the present invention is that the slideway vertical plate is provided with a cylinder opening, one end of the lateral movement cylinder is hinged to the outer side of the slideway vertical plate, and the other end is hinged to the mobile base corresponding to the cylinder opening. The cylinder opening provides space for the lateral movement cylinder to drive the mobile base.

[0013] A further improvement of the present invention is that the bottom of the above-mentioned outrigger oil cylinder is connected to an articulated seat welded on the side cover plate. The articulated seat realizes the connection between the outrigger oil cylinder and the mobile base, and helps to adapt to the inclination of uneven road surface.

[0014] A further improvement of the present invention is that a mechanical leg is provided inside the leg oil cylinder, and the lower part of the mechanical leg is welded to the side cover plate. The mechanical leg can be selected between short-term support and long-term support with the leg oil cylinder.

[0015] A further improvement of the present invention is that the bottom of the outrigger oil cylinder is hinged with an oil cylinder base that can abut against the side cover plate; the outer side of the oil cylinder base is provided with a limit plate welded to the side cover plate and can abut against the oil cylinder base. The oil cylinder base can increase the contact area between the outrigger oil cylinder and the mobile base, and the oil cylinder base and the limit plate cooperate to complete the pushing of the mobile base.

[0016] A vehicle comprises a vehicle body and a transversely movable supporting base device installed below the chassis of the vehicle body.

[0017] It can be seen from the above technical scheme that the beneficial effects of the present invention are as follows: the two ends of the supporting base body are respectively connected to the vehicle body through the outrigger cylinders. After the wheels supporting the vehicle body leave the ground, the lateral moving cylinder is used to realize the movement of the mobile base relative to the slide, thereby pushing the vehicle body to complete the lateral movement, thereby achieving precise lateral displacement and reducing the operating difficulty of the driving operator; the encrypted structure of the two end parts of the mobile base frame can help to increase the higher bearing capacity of the outrigger cylinders and improve the stability during the movement process.

[0026] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in this specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0027] Embodiment 1: like Figure 1-2 As shown, a laterally movable support base device comprises a support base body 1 and an outrigger oil cylinder 5, wherein the outrigger oil cylinder 5 is vertically supported at both ends of the support base body 1, and the outrigger oil cylinder 5 performs a jacking movement to lift the vehicle tire off the ground; the support base body 1 can drive the vehicle chassis to move laterally through the outrigger oil cylinder 5; the support base body 1 comprises a slide 3, a mobile base 2 and a lateral movement oil cylinder 4; the mobile base 2 can move along the slide 3 through the lateral movement oil cylinder 4. After the outrigger oil cylinder 5 extends downward to lift the vehicle tire off the ground, the lateral displacement of the vehicle is completed by the sliding of the support base body 1, thereby realizing lateral movement that can only rely on the cumbersome operation of the driver, and helping to improve the operating efficiency.

[0028] like Figure 4As shown, the slide 3 includes a slide base plate 20, a slide vertical plate 21 and a slide upper plate 22. The slide base plate 20 is provided with the slide vertical plates 21 on both sides corresponding to the moving direction of the mobile base 2, and the upper edge of the slide vertical plates 21 is connected to the slide upper plate 22 horizontally arranged above the slide base plate 20; the slide 3 is an overall U-shaped structure, and the upper edge is provided with an inward-retracted side, which helps to form a better guiding support for the mobile base 2.

[0029] like Figure 2-4 As shown, the slideway vertical plate 21 is provided with a cylinder opening, one end of the lateral moving cylinder 4 is hinged to the outer side of the slideway vertical plate 21, and the other end is hinged to the mobile base 2 corresponding to the cylinder opening; the cylinder opening provides a space for the lateral moving cylinder 4 to drive the mobile base 2. One end of the lateral moving cylinder 4 is rotatably connected to the rear ear plate frame 8 installed on the outer side of the slideway vertical plate 21 through a pin shaft 9, and the other end is rotatably connected to the front ear plate frame 7 installed on the mobile base 2 through the cylinder opening through a pin shaft 9. It is helpful to increase the flexibility and adaptability of the mobile base 2 to move laterally along the slideway 3 through the lateral moving cylinder 4.

[0030] like Figure 4 As shown, the top surface of the slide bottom plate 20 is provided with a plurality of pads 23 protruding upward and contacting the moving base 2, and the length direction of the pads 23 coincides with the moving direction of the moving base 2, and the plurality of pads 23 are evenly distributed along a direction perpendicular to the moving direction of the moving base 2. The pads 23 contact the moving base 2, which helps to avoid wear of the slide bottom plate 20.

[0031] like Figure 3 As shown, the interior of the mobile base 2 is a hollow frame structure, which is enclosed by two opposite side cross beams 10 and two opposite side longitudinal beams 11. The side cross beams 10 coincide with and are parallel to the moving direction of the mobile base 2, and the side cross beams 10 are perpendicular to the moving direction of the mobile base 2. The interior of the frame can be divided into an end portion, a middle portion, and an end portion, each of which occupies one third, in sequence along its length direction (i.e., the moving direction of the mobile base 2).

[0032] The middle section of the frame of the mobile base 2 is evenly distributed with the reinforcing longitudinal beams 13; the middle section of the frame of the mobile base 2 is also provided with a neutral plate 15, the neutral plate 15 is parallel to the moving direction of the mobile base 2, and the two ends of the neutral plate 15 are connected between adjacent reinforcing longitudinal beams 13. It is helpful to improve the overall structural strength of the mobile base 2 through the reinforcing longitudinal beams 13 and the neutral plate 15 in the middle section of the frame.

[0033] A reinforcing longitudinal beam 13 and a reinforcing cross beam 12 are respectively provided at both ends of the frame of the mobile base 2; the reinforcing longitudinal beam 13 is perpendicular to the moving direction of the mobile base 2 along the slide 3; the reinforcing cross beam 12 is parallel to the moving direction of the mobile base 2, and the two side surfaces of the reinforcing cross beam 12 are respectively connected to the frame through a plurality of reinforcing small longitudinal beams 14, and the reinforcing small longitudinal beams 14 are parallel to the reinforcing longitudinal beam 13.

[0034] Side upright plates 16 are also provided at both ends of the frame of the movable base 2 . The side upright plates 16 are parallel to the reinforcing small longitudinal beams 14 , and the side upright plates 16 are located between the side longitudinal beams 11 and the reinforcing small longitudinal beams 14 .

[0035] In order to support a larger weight, the frame of the mobile base 2 is designed as a special grid structure to ensure that it will not be crushed under heavy load (each mobile base 2 supports more than 100 tons). The above beams and plates form a solid grid structure, and through reasonable distribution, the strength of the base itself can be maintained while reducing the use of materials.

[0036] The upper top surface and the lower bottom surface of the frame of the mobile base 2 are respectively covered with a middle cover plate 17 and an edge cover plate 18, wherein the middle cover plate 17 corresponds to the middle section of the frame of the mobile base 2, and the edge cover plate 18 corresponds to the end of the frame of the mobile base 2. The combination of the middle cover plate 17 and the edge cover plate 18 reduces the cost of processing the entire piece of material and the difficulty of operation, and can correspond to the middle section and the end of the frame respectively, which is helpful for subsequent maintenance.

[0037] like Figure 1 As shown, the bottom of the outrigger oil cylinder 5 is connected to a hinge seat welded on the side cover plate 18; the hinge seat is located above the frame end of the mobile base 2 and covers the side stand 16. The connection between the outrigger oil cylinder 5 and the mobile base 2 is achieved through the hinge seat, which helps to adapt to the inclination of uneven road surfaces.

[0038] like Figure 1 As shown, a mechanical leg 6 is also provided on the inner side of the leg oil cylinder 5, and the lower part of the mechanical leg 6 is welded to the side cover plate 18. The mechanical leg 6 can be selected with the leg oil cylinder 5 between short-time support and long-time support.

[0039] like Figure 1 and 3 As shown, the inner side of the mechanical support leg 6 is also provided with a lifting lug 19 installed on the side cover plate 18; the supporting base body 1 can be lifted through the lifting lug 19.

[0040] To sum up, when the device is in use, the outrigger cylinder 5 realizes the action of lowering the support base body 1 and lifting the entire vehicle at the initial stage of operation, so as to release the pressure of the pin shaft 9 fixing the mechanical outrigger 6 and the axle, and facilitate the pulling out of the pin shaft 9 so that the two parts can be extended and retracted; and when the vehicle is parked for a long time and long-term support is required, the mechanical outrigger 6 is directly supported by locking it in place, so that the gravity of the entire vehicle is transferred from the outrigger cylinder 5 to the mechanical outrigger 6, thereby avoiding damage to the hydraulic system and pipelines caused by long-term pressure on the outrigger cylinder 5.

[0041] like Figure 6 As shown, a finite element analysis is performed on the structure of the support base body 1, and a load of 120t is applied thereto. It can be seen that the stress condition of the entire base is good, and the overall structure can be kept intact under heavy load.

[0042] Embodiment 2: like Figure 5 As shown, the bottom of the outrigger oil cylinder 5 is hinged with an oil cylinder base 25 that can abut against the side cover plate 18; the outer side of the oil cylinder base 25 is provided with a limit plate 26 that is welded on the side cover plate 18 and can abut against the oil cylinder base 25. The oil cylinder base 25 can increase the contact area between the outrigger oil cylinder 5 and the mobile base 2, and the oil cylinder base 25 and the limit plate 26 cooperate to complete the pushing of the mobile base 2. Reinforcing ribs 27 are evenly distributed between the limit plate 26 and the side cover plate 18.

[0043] A vehicle comprises a vehicle body and a transversely movable supporting base device installed below the chassis of the vehicle body.

[0044] The present invention describes a transversely movable supporting base device and vehicle, wherein the two ends of the supporting base body are respectively connected to the vehicle body through leg cylinders. After the wheels of the supporting vehicle body leave the ground, the lateral moving cylinder is used to realize the movement of the movable base relative to the slideway, thereby pushing the vehicle body to complete the lateral movement, thereby achieving precise lateral displacement and reducing the operating difficulty of the driving operator; the encrypted structure of the two end parts within the movable base frame can help to increase the higher bearing capacity of the leg cylinders and improve the stability during the movement.

[0045] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
