Description

Technical Field

[0001] The utility model relates to a vehicle-mounted gas cylinder frame, in particular to a double-bottle group gas cylinder frame. Background Art

[0002] The traditional double-bottle gas cylinder frame is usually composed of a two-layer frame, two main saddles fixed to the upper layer of the frame, and two main saddles fixed to the lower layer of the frame. The two main saddles on the upper layer of the frame are used to support one gas cylinder, and the two main saddles on the lower layer of the frame are also used to support one gas cylinder. Among them, the support plate on the saddle for supporting the gas cylinder is fixed to the saddle by welding. For the double-bottle gas cylinder frame used in heavy trucks and other transport vehicles, in order to meet long-distance needs, the capacity of a single gas cylinder is usually more than one thousand liters. For example, the most common 1350L liquefied natural gas cylinder has a heavy overall weight. Therefore, in order to ensure the supporting strength of the support plate, it is also necessary to weld several reinforcing ribs between the main saddle and the support plate. A large amount of welding is required in the manufacturing process of the entire frame, which is greatly affected by welding. There are difficult-to-overcome problems such as large welding deformation, many weld defects, the need to equip professional welding technicians, welding quality affected by the level of technicians, and poor product consistency. In addition, the double-bottle gas cylinder frame of the above-mentioned structure usually has an overall weight of more than 400 kilograms, which is heavy. For the double-bottle gas cylinder frame used in heavy trucks and other transport vehicles, when loading gas cylinders of the same capacity, the heavier the frame, the shorter the actual cruising range of the transport vehicle and the higher the transportation cost. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a double-bottle group gas cylinder frame with simple and compact structure, small occupied space, strong bearing capacity and light weight.

[0004] In order to solve the problems of large welding deformation, many weld defects, heavy frame weight, etc., the technical solution adopted by the utility model is: the double-bottle group gas cylinder frame described above includes: two main saddles, two upper crossbeams, two lower crossbeams, and two middle support plates. Among them, the main saddle includes: a main support plate, a semicircular hole is opened on the top surface of the main support plate, the arc edge of the semicircular hole is turned inward to form an arc support plate for supporting the gas cylinder, the straight edges around the main support plate are folded inward or pressed inward to form a side frame, and the side frames around are connected to the arc support plate end to end to form a closed outer frame. The end-to-end connection method here can be welded, and the amount of welding in this part is small, so the impact on the overall deformation of the frame can be basically ignored. A circular hole is also opened on the main support plate, and the arc edge of the circular hole is turned inward to form a cylindrical support plate for supporting the gas cylinder; the outer frame, arc support plate, and cylindrical support plate on the same main saddle are all located on the same side of the main support plate;

[0005] The left and right sides of the tops of the two main saddles are connected by an upper crossbeam respectively, the left and right sides of the bottoms of the two main saddles are connected by a lower crossbeam respectively, and the left and right sides of the two main saddles are connected by a middle support plate respectively, so that the two main saddles, the two upper crossbeams, the two lower crossbeams, and the two middle support plates are connected to form a rectangular parallelepiped frame structure, and the arc-shaped support plates on the two main saddles are arranged facing each other;

[0006] An upper auxiliary saddle and a lower auxiliary saddle are also provided on each main saddle, wherein the upper auxiliary saddle is fixedly provided on the main support plate at the semicircular hole, and the upper auxiliary saddle and the arc-shaped support plate are respectively located on the front and rear sides of the main support plate; the lower auxiliary saddle is fixedly provided on the main support plate at the circular hole, and the lower auxiliary saddle and the cylindrical support plate are respectively located on the front and rear sides of the main support plate;

[0007] The upper auxiliary support seat and the lower auxiliary support seat have the same structure, and the specific structure includes: an arc-shaped auxiliary support plate for supporting the gas cylinder and a fixed connection plate for fixedly connecting with the main support plate, wherein the fixed connection plate and the main support plate are preferably connected by bolts. The arc-shaped auxiliary support plate and the fixed connection plate are formed into an integral structure by flanging the same plate, and a drawstring support for fixing the end of the drawstring is respectively provided at the angle space between the left and right ends of the arc-shaped auxiliary support plate and the fixed connection plate.

[0008] In order to make the overall structure more compact, reduce the occupied space and reduce the overall weight, the arc of the semicircular hole in this solution is selected as a minor arc, and the circular hole is located directly below the semicircular hole.

[0009] In order to prevent the gas cylinders loaded in the double-bottle gas cylinder frame from circumferential rotation, the present invention has two auxiliary support plates fixedly arranged on the fixed connecting plate. The two auxiliary support plates extend out of the arc-shaped secondary support plate. An auxiliary connecting plate for welding and fixing to the gas cylinder is fixedly arranged on each auxiliary support plate. The auxiliary connecting plates are fixed to the gas cylinders by welding, thereby fixing the circumferential position of the gas cylinders.

[0010] In order to further enhance the overall strength of the double-bottle group gas cylinder frame, an oblique support structure can be additionally provided on the basis of the above structure, specifically: a bottom connecting beam is fixedly provided on the side frame at the bottom of each main saddle; the left ends of the two bottom connecting beams extend outward from the corresponding main saddles, or the right ends of the two bottom connecting beams extend outward from the corresponding main saddles; an oblique support is provided obliquely between the bottom connecting beam extending out of the left end of each main saddle and the side frame on the left side of the main saddle, or an oblique support is provided obliquely between the bottom connecting beam extending out of the right end of each main saddle and the side frame on the right side of the main saddle.

[0011] The thickness of the main saddle in the double-bottle gas cylinder frame can be made thinner. On the basis of being thinner, in order to ensure the strength of the main saddle, the present invention provides a first reinforcing plate at the main support plate on the left side of the circular hole and the side frame on the left side of the main support plate, and a second reinforcing plate at the main support plate on the right side of the circular hole and the side frame on the right side of the main support plate;

[0012] The first reinforcement plate and the second reinforcement plate have the same structure, and the specific structure includes: a first reinforcement connecting plate and a second reinforcement connecting plate, the first reinforcement connecting plate and the second reinforcement connecting plate are formed by bending or pressing the flanges of the same plate to form an integrated structure, the first reinforcement connecting plate is fixedly connected to the main support plate, and the second reinforcement connecting plate is fixedly connected to the side frame of the main support plate; wherein, the method of fixing the first reinforcement connecting plate to the main support plate and the method of fixing the second reinforcement connecting plate to the side frame of the main support plate are preferably bolted.

[0013] There are two types of positions for the first reinforcing connecting plate and the second reinforcing connecting plate, and you can choose one of the two positions. The first position is: the first reinforcing connecting plate and the second reinforcing connecting plate are both wrapped around the outer periphery of the main support plate and the side frame of the main support plate. The second position is: the first reinforcing connecting plate and the second reinforcing connecting plate are both embedded in the inner periphery of the main support plate and the side frame of the main support plate. Under this structure, it is not necessary to add diagonal supports, but in order to further improve the overall strength, diagonal supports can also be added. When adding diagonal supports, the tops of the two diagonal supports are usually connected to the second reinforcing connecting plate on the corresponding main saddle.

[0014] Furthermore, in the aforementioned double-bottle gas cylinder frame, the middle support plate comprises: a middle plate and connecting beams extending in four directions along the edges of the middle plate, the middle plate and the four connecting beams are integrally formed to form an X-shaped structure; the edges of two adjacent connecting beams and the edge of the middle plate located between the two connecting beams are folded inwards or pressed inwards to form the inner side edges of the integral structure, and the ends of the four connecting beams are respectively fixedly connected to the side frames of the corresponding main saddle sides. The middle support plate is preferably connected to the weakest point of the main saddle, that is, the side frame where the circular hole is located.

[0015] In this solution, the strength of the main saddle is strengthened by the cooperation of the first reinforcing connecting plate, the second reinforcing connecting plate and the middle supporting plate, ensuring that the main saddle can still meet the strength requirements after the plate is made thinner, further reducing the overall weight and making the overall frame more lightweight.

[0016] Furthermore, in the aforementioned double-bottle gas cylinder frame, the upper crossbeam is composed of a first connecting plate and a second connecting plate, the first connecting plate and the second connecting plate are formed by bending or pressing the same plate to form an integral structure with an L-shaped cross section, the first connecting plate is fixedly connected to the side frame of the top of the main saddle, and the second connecting plate is fixedly connected to the side frame of the side of the main saddle;

[0029] The technical solution of the present utility model is further described in detail below in conjunction with the accompanying drawings and preferred embodiments. Embodiment 1

The main saddle 1 includes: a main support plate 11, on the top surface of which a semicircular hole 12 is provided. In this embodiment, the arc of the semicircular hole 12 is preferably selected as a minor arc, that is, an arc with a central angle less than 180 degrees. The arc edge of the semicircular hole 12 is turned inward to form an arc support plate 13 for supporting the gas cylinder. The straight edges of the main support plate 11 are folded inward or pressed inward to form a side frame 14. The side frames 14 are connected end to end with the arc support plate 13 to form a closed outer frame.

[0031] Among them, considering the compactness of the overall structure and the problem of occupied space, in this embodiment, the circular hole 15 is arranged directly below the semicircular hole 12, and at this time the overall occupied space is the smallest in the horizontal direction.

[0032] For the convenience of description, this embodiment uses Figure 1 The left-hand direction shown is defined as "left", with Figure 1 The right-hand direction shown is defined as "right", with Figure 2 The left-hand direction shown is defined as "front", with Figure 2 The right-hand direction shown is defined as "rear", and all references to "left", "right", "front", and "rear" in this embodiment are based on the above definition. It should also be noted that the directions or positional relationships indicated by the terms "left", "right", "front", and "rear" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0033] The left and right sides of the tops of the two main saddles 1 are connected by an upper crossbeam 2, respectively, and the connection method is preferably bolted. The left and right sides of the bottoms of the two main saddles 1 are connected by a lower crossbeam 3, respectively, and the connection method is preferably bolted. The left and right sides of the two main saddles 1 are connected by a middle support plate 4, respectively, and the connection method is preferably bolted, so that the two main saddles 1, the two upper crossbeams 2, the two lower crossbeams 3, and the two middle support plates 4 are connected to form a rectangular frame structure, and the arc-shaped support plates 13 on the two main saddles 1 are arranged facing each other, such as Figure 3 shown.

[0034] like Figure 3 As shown, the upper cross beam 2 is composed of a first connecting plate 21 and a second connecting plate 22. The first connecting plate 21 and the second connecting plate 22 are formed by bending or pressing the same plate to form an integral structure with an L-shaped cross-section. Such a structure has good bearing capacity, wherein the two ends of the first connecting plate 21 are respectively fixedly connected to the side frames 14 on the top of the corresponding main saddle 1, and the two ends of the second connecting plate 22 are respectively fixedly connected to the side frames 14 on the side of the corresponding main saddle 1.

[0035] like Figure 3 As shown, the middle support plate 4 includes: a middle plate 41 and connecting beams 42 extending in four directions along the edges of the middle plate 41 respectively, and the middle plate 41 and the four connecting beams 42 are integrally formed to form an X-shaped structure; the edges of the two adjacent connecting beams 42 and the edge of the middle plate 41 located between the two connecting beams 42 are folded inwards or pressed inwards to form an inner side edge 43 of an integral structure. Such a structure has good bearing capacity, and the ends of the four connecting beams 42 are respectively fixedly connected to the side frames 14 on the side of the corresponding main saddle 1, and the fixed connection method is preferably bolted.

[0036] like Figure 3As shown, the lower cross beam 3 is composed of a third connecting plate 31 and a fourth connecting plate 32, and the third connecting plate 31 and the fourth connecting plate 32 are formed by bending or pressing the same plate to form an integral structure with an L-shaped cross-section. Such a structure has good bearing capacity, wherein the two ends of the third connecting plate 31 are respectively fixedly connected to the side frame 14 of the corresponding side of the main saddle 1, and the two ends of the fourth connecting plate 32 are respectively fixedly connected to the side frame 14 of the bottom of the corresponding main saddle 1.

[0037] An upper sub-saddle 5 and a lower sub-saddle 6 are also provided on each main saddle 1. The upper sub-saddle 5 is fixedly arranged on the main support plate 11 at the semicircular hole 12, and the upper sub-saddle 5 and the arc-shaped support plate 13 are respectively located on the front and rear sides of the main support plate 11; the lower sub-saddle 6 is fixedly arranged on the main support plate 11 at the circular hole 15, and the lower sub-saddle 6 and the cylindrical support plate 16 are respectively located on the front and rear sides of the main support plate 11.

[0038] The upper auxiliary support seat 5 and the lower auxiliary support seat 6 have the same structure, which includes: an arc-shaped auxiliary support plate 51 for supporting the gas cylinder and a fixed connecting plate 52 for fixedly connecting with the main support plate 11, and the fixed connecting plate 52 is preferably fastened to the main support plate 11 by multiple bolts. The arc-shaped auxiliary support plate 51 and the fixed connecting plate 52 are formed into an integral structure by flanging the same plate, and a drawstring support 53 for fixing the end of the drawstring is respectively arranged at the angle space between the left and right ends of the arc-shaped auxiliary support plate 51 and the fixed connecting plate 52, and the drawstring support 53 is also preferably fixed by bolt connection.

[0039] At present, in the application process of the gas cylinder frame, the support plates used to support the gas cylinders are basically welded to the gas cylinder frame by welding. Welding deformation and weld defects are the inevitable primary problems. In the present embodiment, the arc support plate 13 is obtained by inwardly flanging the arc edge of the semicircular hole 12, the cylindrical support plate 16 is obtained by inwardly flanging the arc edge of the circular hole 15, the side frame 14 is obtained by folding the straight edges of the main support plate 11 inwardly or pressing and flanging them inwardly, and the upper auxiliary support seat 5 and the lower auxiliary support seat 6 are also flanging. Basically, there is no large-area welding involved here. At most, a small amount of welding connection is used when the side frames 14 on all sides are connected to the arc support plate 13 end to end to form a closed outer frame. The influence of this part of welding on the overall structure of the gas cylinder frame can be ignored. Therefore, it is not troubled by welding deformation and weld defects. This is one of them. Secondly, after welding, several reinforcing ribs need to be welded to ensure the support strength. In this embodiment, the structural strength after flanging and folding can meet the requirements, and no additional welding of reinforcing ribs is required. The weight of the overall structure is reduced by about half. The weight of the overall structure is usually more than 200 kilograms, which has the advantage of being lightweight compared to traditional structures. Thirdly, the labor intensity and labor cost are reduced. There is no need for a large number of professional welding technicians to weld, and the working environment is also improved. There is no need to consider the welding consistency problem. Only the mold cost needs to be invested in the early stage, and the later investment is small. The product consistency is good, the qualified rate is greatly improved, and the efficiency is greatly improved. In general, the overall production and manufacturing cost is also greatly reduced.

[0040] like Figure 2 and Figure 3 As shown, two auxiliary support plates 8 are fixedly arranged on the fixed connection plate 52, and the two auxiliary support plates 8 extend out of the arc-shaped secondary support plate 51. An auxiliary connection plate 81 for welding and fixing with the gas cylinder is fixedly arranged on each auxiliary support plate 8, wherein the auxiliary support plate 8 can be fixed to the fixed connection plate 52 by bolts shared with the fixed connection plate 52 when it is fixed to the main support plate 11, or can be fixed by bolts with additional holes. When the gas cylinder is placed on the arc-shaped secondary support plate 51, in order to prevent the gas cylinder from rotating circumferentially, the gas cylinder is fixed in the circumferential position by welding the gas cylinder and the auxiliary connection plate 81. Embodiment 2

[0041] This embodiment is based on the first embodiment, and the plates of the two main saddles 1 in the first embodiment are made thinner. Although the thinner plates can reduce the material cost, the problem brought about at the same time is that the bearing capacity of the main saddle 1 is also reduced. In order to ensure the bearing capacity of the main saddle 1, as Figure 4 , Figure 5 and Figure 6As shown, in this embodiment, a first reinforcement plate 71 is provided on the main support plate 11 located on the left side of the circular hole 15 and the side frame 14 on the left side of the main support plate 11, and a second reinforcement plate 72 is provided on the main support plate 11 located on the right side of the circular hole 15 and the side frame 14 on the right side of the main support plate 11.

[0042] The first reinforcement plate 71 and the second reinforcement plate 72 have the same structure, which includes: a first reinforcement connecting plate 711 and a second reinforcement connecting plate 712. The first reinforcement connecting plate 711 and the second reinforcement connecting plate 712 are formed by bending or pressing the same plate to form an integral structure. The first reinforcement connecting plate 711 is fixedly connected to the main support plate 11, and the second reinforcement connecting plate 712 is fixedly connected to the side frame 14 of the main support plate 11; wherein, the method of fixing the first reinforcement connecting plate 711 to the main support plate 11 and the method of fixing the second reinforcement connecting plate 712 to the side frame 14 of the main support plate 11 are preferably bolted.

[0043] The first reinforcement connecting plate 71 and the second reinforcement connecting plate 72 may be arranged outside the main saddle 1 , that is, the first reinforcement connecting plate 71 and the second reinforcement connecting plate 72 are both wrapped around the periphery of the main support plate 11 and the side frame 14 of the main support plate 11 .

[0044] The first reinforcement connecting plate 71 and the second reinforcement connecting plate 72 can also be arranged in the recessed portion of the main saddle 1 , that is, the first reinforcement connecting plate 71 and the second reinforcement connecting plate 72 are both embedded in the inner periphery of the main support plate 11 and the side frame 14 of the main support plate 11 .

[0045] The above-mentioned solution of adding the first reinforcing plate 71 and the second reinforcing plate 72 and thinning the plate material of the main saddle 1 can further reduce the weight of the double-bottle group gas cylinder frame on the basis of the first embodiment while ensuring the bearing capacity of the double-bottle group gas cylinder frame. Embodiment 3

[0046] This embodiment is based on the first or second embodiment and further includes two bottom connecting beams 9 and two oblique supports 91 to further improve the overall strength of the double-bottle group gas cylinder frame.

[0047] The specific structure of adding two bottom connecting beams 9 and two oblique supports 91 to the double-bottle group gas cylinder frame without the first reinforcing plate 71 and the second reinforcing plate 72 is as follows: Figure 7 and Figure 8 As shown, a bottom connecting beam 9 is fixedly provided on the side frame 14 at the bottom of each main saddle 1, and the two are preferably fixedly connected by bolt connection; the left ends of the two bottom connecting beams 9 extend outward from the corresponding main saddle 1, or the right ends of the two bottom connecting beams 9 extend outward from the corresponding main saddle 1.

[0048] When the left ends of the two bottom connecting beams 9 are extended outward from the corresponding main saddle 1, an oblique support 91 is obliquely supported between the bottom connecting beam extending outward from the left end of each main saddle 1 and the side frame 14 on the left side of the main saddle 1. When the right ends of the two bottom connecting beams 9 are extended outward from the corresponding main saddle 1, an oblique support 91 is obliquely supported between the bottom connecting beam 9 extending outward from the right end of each main saddle 1 and the side frame 14 on the right side of the main saddle 1.

[0049] The specific structure of adding two bottom connecting beams 9 and two oblique supports 91 to the double-bottle group gas cylinder frame with the first reinforcement plate 71 and the second reinforcement plate 72 is as follows: Figure 7 and Figure 8 As shown, a bottom connecting beam 9 is fixedly provided on the side frame 14 at the bottom of each main saddle 1, and the two are preferably fixedly connected by bolt connection; the left ends of the two bottom connecting beams 9 extend outward from the corresponding main saddle 1, or the right ends of the two bottom connecting beams 9 extend outward from the corresponding main saddle 1.

[0050] When the left ends of the two bottom connecting beams 9 both extend outwards from the corresponding main saddle 1, an oblique support 91 is obliquely supported between the bottom connecting beam extending outwards from the left end of each main saddle 1 and the second reinforcing connecting plate 712 on the left side of the main saddle 1. When the right ends of the two bottom connecting beams 9 both extend outwards from the corresponding main saddle 1, an oblique support 91 is obliquely supported between the bottom connecting beam 9 extending outwards from the right end of each main saddle 1 and the second reinforcing connecting plate 712 on the right side of the main saddle 1.

[0051] The above description is only a preferred embodiment of the present invention and does not constitute any other limitation on the present invention. Any modification or equivalent change made based on the technical essence of the present invention still falls within the scope of protection required by the present invention.
