Description

Technical Field

[0001] This invention relates to the field of cargo transportation technology, specifically to a transfer adapter assembly and a transfer vehicle. Background Technology

[0002] For the transport of large and heavy items, the items must be securely fixed to the transport vehicle. To accommodate the shape and structure of the items, a transport adapter is typically used as a transition between the vehicle and the item. The adapter is fixed to the support platform of the vehicle, and the item is fixed to the adapter. Since transport items have circular, square, and irregular cross-sectional shapes, a separate transport adapter is currently designed for each type of cross-section to ensure secure fastening. This adaptation method results in a large number of adapter models and specifications, leading to higher manufacturing costs. Changing between different adapters requires complete removal and disassembly, making it inconvenient to use and difficult to store and manage. Summary of the Invention

Detailed Implementation

[0038] The basic concept of this invention is to make the carrier fixing structure universal while the transport object fixing structure is set independently, forming a modular transport adapter assembly. Different types of fixing components can be installed on the same universal base. The universal base serves as the main load-bearing body and provides the installation foundation. By utilizing the installation structure of its various components, it meets the different installation position requirements of different fixing components and adapts to transport objects of different sizes and shapes. The universal base does not need to be replaced; only the fixing components need to be replaced, making it convenient to use.

[0039] The following detailed description is provided in conjunction with specific embodiments. Embodiments of the transfer adapter assembly of the present invention: This transfer adapter assembly serves as a mechanical interface for low-speed, short-distance vehicle transfers. The corresponding transfer vehicle is a vehicle, and the transfer adapter assembly is fixed to the vehicle's carrying platform. It adapts to the shape and size of the transferred goods, providing stable support and fixation. The vehicle's width direction is the left-right direction, and its length direction is the front-back direction, which is also the corresponding direction of the transfer adapter assembly.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown in the five figures, these figures illustrate the status of the transfer adapter assembly transferring five types of transport items, from... Figures 1 to 5 The five types of transport objects are, in order: small irregular cross-section transport object 101, large irregular cross-section transport object 102, circular cross-section transport object 103, rectangular cross-section transport object 104, and transport object with only side and bottom support 105. That is, the transport adapter assembly in this embodiment can be adapted to these five types of transport objects.

[0041] Each transport object is shown from one side view in the front-to-back direction. The main differences between the transport objects are their outer circular outline shape and cross-sectional area. Each transport object has a certain length, which is in the front-to-back direction. During transport, the transport object is arranged along the length of the vehicle and fixed to the transport adapter assembly. Two or more transport adapter assemblies can be set, spaced apart front to back, to accommodate longer transport objects, while the transport adapter assemblies themselves do not need to be very long.

[0042] The transfer adapter assembly includes a universal base and a fixing component. The fixing component is used to fix the transfer object. The universal base has a carrier fixing structure for fixing to the transfer vehicle and a component mounting structure for mounting the fixing component. There are two or more component mounting structures. For the transfer object, a corresponding fixing component is used and installed on the corresponding component mounting structure.

[0043] There is one or more fixing components; in this embodiment, there are four. Figure 1 and Figure 2 The same type of fixing component is used for the transported items. Figure 3 , Figure 4 , Figure 5 Each transport item uses a different fixing component. The type of fixing component is configured and selected according to the transport item. For each type of transport item, a suitable fixing component is selected and installed on a universal base to form a transport adapter, which then secures the transport item to the adapter. Different fixing components, combined with the universal base, can form different transport adapters. Different transport adapters can share the same universal base, share some components, or share some of the component mounting structures on the universal base.

[0044] In this embodiment, based on the adaptation of five types of transport objects, there are five corresponding component mounting structures on the universal base. Different component mounting structures can correspond to different fixing components. For small irregular cross-section transport objects 101 and large irregular cross-section transport objects 102 that use the same fixing component, their fixing components are installed in different positions on the universal base. That is, different transport objects correspond to different fixing component installation states. Each transport object corresponds to a transport adapter component combination state. In each combination state, the universal base is the foundation and remains unchanged, while the fixing components change in type or position. In other embodiments, as needed, there may be only one type of fixing component, while the position of the fixing component can be changed using two or more component mounting structures provided on the universal base to adapt to transport objects of different specifications, such as... Figure 1 , Figure 2 The state shown; or only two or three fixed components can be set.

[0045] The various components form modular units that can be flexibly combined and selected according to needs. This modular adapter assembly features a universal carrier fixing structure and an independent transport object fixing structure. Different types of fixing components can be installed on the same universal base. The universal base serves as the main load-bearing structure and provides the installation foundation. Utilizing the mounting structure of its various components, it meets the different installation position requirements of different fixing components, adapting to transport objects of different sizes and shapes. The universal base does not need to be replaced; only the fixing components need to be replaced, saving costs, facilitating handling and disassembly, and improving ease of use.

[0046] The universal base includes a bracket 1, and a fixing component is connected to the bracket 1. Figure 1 and Figure 2 One type of fixing assembly shown includes a triangular bracket 2, a roller 3, and a bolt 4. Figure 3 One type of fixing component shown includes a roller 3 and a bolt 4. Figure 4 One type of fastening assembly shown includes a support beam 7 and a bolt 4. Figure 5 One type of fixing component shown includes a roller 3 and a side support assembly 8.

[0047] The universal base has an upward-facing mounting groove on the bracket 1, with space inside for inserting transported items. The bottom surface of the mounting groove is a concave arc surface, and the two side walls are sloped surfaces tangent to the arc surface. The distance between the two side walls of the mounting groove gradually increases from the bottom to the opening, forming a wide-mouth structure to facilitate the installation and fixing of components and transported items. In other embodiments, the inner wall surface of the mounting groove may also be entirely an arc surface.

[0048] Bracket 1 constitutes the base body of the universal base, combined with Figure 6 , Figure 7 , Figure 8 The bracket 1 includes a main frame and a support 14. The main frame includes two side plates 11 arranged opposite each other and a connector fixed between the two side plates 11, making the bracket 1 a frame structure. The component mounting structure is set on the side plates 11, and a space is formed between the two side plates 11 to avoid the fixing components. In other embodiments, the bracket can also be integrally formed, and the bracket has a clearance cavity for the fixing components to be installed.

[0049] The two side plates 11 are symmetrical front to back, and each side plate 11 itself is symmetrical left to right. The thickness direction is the front-to-back direction, the left-to-right direction is its width direction, and the top-to-bottom direction is its height direction. The component mounting structure includes pin holes on the two side plates 11, with each pin hole corresponding to the previous one. The side plates 11 are divided into left and right parts by their center lines in the left-to-right direction. Each left and right part of the side plate 11 has five pin holes: a first bracket pin hole 1a, a second bracket pin hole 1b, a third bracket pin hole 1c, a fourth bracket pin hole 1d, and a fifth bracket pin hole 1e, which are used to connect corresponding fixing components. In other embodiments, bolt holes can also be provided for bolt connection and fixing of the components.

[0050] The upper edge of the side plate 11, i.e., its upper surface, includes a concave arc section 1f and a sloping section 1g. The sloping section 1g has two segments, located on the left and right sides of the concave arc section 1f and connected to each other. The concave arc section 1f and the sloping section 1g make the upper part of the side plate 11 a groove structure. The groove structures of the two side plates 11 together form the upward mounting groove of the bracket 1. The concave arc section 1f forms the bottom arc surface of the mounting groove, and the sloping section 1g forms the side wall slope of the mounting groove. The bracket 1 has inverted V-shapes on both sides. When the middle horizontal section of the lower edge is fixed, the side plate 11 forms a beam of equal strength with a large root section and a small distal section.

[0051] The lower edge of the side plate 11, i.e., its lower surface, includes a horizontal lower edge segment 1h and a sloped lower edge segment 1i. The horizontal lower edge segment 1h is located in the middle of the side plate 11 in the left-right direction. The sloped lower edge segment 1i has two segments located on the left and right sides of the horizontal lower edge segment 1h and connected to each other. The distance between the two sloped lower edge segments 1i gradually increases from bottom to top, making the two ends of the universal base higher than the middle in the width direction. The left and right sides of the side plate 11 are vertical surfaces. The lower surface of the side plate 11 also includes planar segments located at the ends in the left-right direction. The sloped lower edge segment 1i transitions to the planar segment with an arc, the planar segment transitions to the vertical surface with an arc, and the vertical surface transitions to the sloped upper edge segment 1g with an arc.

[0052] The first bracket pin hole 1a and the second bracket pin hole 1b are located near the left and right edges of the side plate 11, and are vertically aligned. The second bracket pin hole 1b is located at the top of the side plate 11, and the first bracket pin hole 1a is located near the flat section of the lower surface of the side plate 11. The second bracket pin hole 1b, the third bracket pin hole 1c, the fourth bracket pin hole 1d, and the fifth bracket pin hole 1e are arranged sequentially at intervals along the extension direction of the groove sidewall of the side plate 11. The fifth bracket pin hole 1e is located below the bottom surface of the arc groove of the mounting groove of the universal base.

[0053] The connecting components that fix the two side plates 11 include a connecting post 12, a connecting block 16, an inclined bottom plate 13, and a flat bottom plate 15. Both the left and right sides of the side plate 11 are fixed with these connecting components. Two connecting posts 12 and two inclined bottom plates 13 are provided, symmetrically distributed. The inclined bottom plate 13 is fixed at the corresponding position of the lower edge inclined section 1i of the lower edge of the side plate 11 and is flush with the lower edge. The flat bottom plate 15 is fixed at the corresponding position of the lower edge horizontal section 1h of the lower edge of the side plate 11 and is located above the lower edge horizontal section 1h. The flat bottom plate 15 is fixed in the middle of the left and right directions of the side plate 11. The connecting post 12 is fixed near the left and right ends of the side plate 11. The connecting block 16 is fixed in the middle of the left and right directions of the side plate 11. The vertical dimension of the connecting block 16 is greater than the thickness of the flat bottom plate 15, and the thickness direction of the flat bottom plate 15 is vertical. The front and rear sides of the connecting block 16 are fixed to the two side plates 11 respectively. The connecting block 16 has a through hole extending vertically at its center. The lower hole of the through hole is blocked by the flat bottom plate 15, and the upper end of the connecting block 16 does not protrude beyond the upper edge of the side plate 11. The flat bottom plate 15 and the two side plates 11, as well as the inclined bottom plate 13 and the two side plates 11, all form a bracket frame structure 1j. Each connecting piece and the bracket 14 can be welded and fixed to the side plate 11.

[0054] The support 14 is fixed at the center of the bottom of the bracket 1. There are two supports 14, spaced apart on the left and right. The supports 14 extend in the front-to-back direction and have a U-shaped frame structure in cross-section, which can be made of channel steel. The support 14 includes an upper wall 14b and left and right side walls 14c. The upper wall 14b protrudes upward from the flat bottom plate 15, and the side walls 14c protrude downward from the lower edge of the side plate 11. The bottom of the support 14 protrudes from the bottom of the bracket 1. The front-to-back dimension of the support 14 is larger than that of the main frame in the front-to-back direction. Both the front and rear ends of the support 14 protrude from the side plate 11.

[0055] The inner cavity of the support 14 forms a limiting groove, which faces downward and extends through the front and rear directions, in conjunction with... Figure 9 , Figure 10 The carrier fixing structure is a limiting strip 6 that is adapted to be installed in the limiting groove of the bracket 14. The bottom of the limiting strip 6 has a part for fixing to the transfer carrier. The carrier fixing structure is located in the middle of the width direction of the universal base. The length of the limiting strip 6 is greater than the length of the limiting groove, that is, the length of the limiting strip 6 is greater than the front-rear length of the bracket 14. The limiting strip 6 has a square cross-section and is adapted to the limiting groove of the bracket 14. There are two limiting strips 6. The two brackets 14 of the same bracket 1 are respectively locked on the two limiting strips 6. The upper wall 14b of the bracket is supported on the upper surface 6b of the limiting strip. The side wall 14c of the bracket cooperates with the limiting strip 6 to restrict the left and right movement of the bracket 1. Multiple transfer adapter assemblies can share the limiting strip 6. The bottom of the limiting strip 6 can be welded and fixed to the vehicle's carrying platform. In other embodiments, the limiting strips may not be shared.

[0056] A notch is provided in the middle of the front-rear direction of the side wall 14c of the bracket to reduce friction. Notches are provided at both the front and rear ends of the upper wall 14b of the bracket. A bracket pin hole 14a is provided at both the front and rear ends of the side wall 14c of the bracket, forming a connecting hole that passes through the limiting groove of the bracket 14. Multiple limiting strip pin holes 6a are provided on the limiting strip 6 along the front-rear direction, and the limiting strip pin holes 6a are continuous in the left-right direction. The bracket pin hole 14a cooperates with the corresponding limiting strip pin hole 6a to allow the insertion of a pin 5 and achieve front-rear position fixation. The large number of limiting strip pin holes 6a allows for adjustment of the front-rear position of the bracket 1 relative to the limiting strip 6, using different limiting strip pin holes 6a to achieve its front-rear position fixation. In other embodiments, the limiting strip may be omitted, and a bolt fixing seat may be provided at the bottom of the bracket, directly fixing it to the vehicle's load-bearing platform using bolts.

[0057] In this embodiment, the fixing component is also connected to the bracket 1 via a pin 5. The pin 5 of the component mounting structure passes through the corresponding pin holes on the two side plates 11 for connecting and fixing the component. The pin holes that cooperate with the pin 5 connecting and fixing the component are the first bracket pin hole 1a, the second bracket pin hole 1b, the third bracket pin hole 1c, the fourth bracket pin hole 1d, and the fifth bracket pin hole 1e.

[0058] A gap is left between the two side plates 11 to accommodate the triangular bracket 2, roller 3, bolt 4, support beam 7, and side support assembly 8. The left and right sides of the middle horizontal section of the lower edge of the side plate 11 are fixed to two parallel brackets 14. The bracket 14 is long and narrow with a frame-shaped cross-section and an opening facing downwards. Several bracket pin holes 14a are provided on both vertical surfaces. The limiting strip 6 is long and narrow with a rectangular cross-section and several limiting strip pin holes 6a are provided on its vertical surface. The limiting strip 6 is fixedly installed on the upper surface of the vehicle in pairs through its lower surface, and the parallel spacing is consistent with the spacing between the two brackets 14 on the bracket 1.

[0059] The bracket 1 is placed on the upper surface of the limiting strip 6 via the upper wall 14b of the bracket base. When the pin holes on the bracket base 14 and the pin holes on the limiting strip 6 are aligned, the pin 5 can be smoothly inserted into all the aligned pin holes, preventing the pin 5 from being stressed and difficult to insert or remove during normal transport. Two sloping bottom plates 13 are provided on both sides of the lower edge between the two side plates 11 of the bracket 1, and a flat bottom plate 15 is provided in the middle, which fixes the two side plates 11 together to form an upward-opening frame shape, enhancing the overall stability of the bracket 1. The sloping bottom plates 13 do not block the downward openings formed at the left and right ends of the lower edge of the two side plates 11, leaving sufficient space for the installation of the side support assembly 8.

[0060] The two side plates 11 of the bracket 1 and the various connecting parts fixed between them further secure the two side plates 11 together, further enhancing the overall stability of the bracket 1. The arrangement of the connecting parts should not affect the installation of the triangular bracket 2, roller 3, fastener 4, support beam 7 and side support assembly 8 on the bracket 1. Fastener 4 is existing technology.

[0061] Combination Figure 1 , Figure 11 , Figure 12 , Figure 13 , Figure 14 As shown, the roller 3 of this fixing component is mounted on the triangular bracket 2, which is also the roller bracket. The two legs of the triangular bracket 2 are of different lengths to accommodate the pin holes at the upper edge of the side plate 11. The two legs are respectively provided with a first bracket pin hole 2a and a second bracket pin hole 2b. The top of the triangular bracket 2 is provided with a third bracket pin hole 2c and a bracket groove 2d. The third bracket pin hole 2c passes through the front and rear side walls of the bracket groove 2d. The bracket groove 2d is for the roller 3 to be fitted into. The roller 3 is provided with a roller pin hole 3a. The roller pin hole 3a corresponds to the third bracket pin hole 2c so that the pin 5 is inserted to serve as the pivot of the roller 3.

[0062] Roller 3 is used to support the transported goods. One roller 3 and one triangular bracket 2 form a support unit. Figure 1The fixing component has two support units, which are installed on the left and right sides of the bracket 1 respectively. The fastener 4 is used to fasten the transported object. The roller 3 has an upper outer cylindrical surface 3b for supporting the outer circle of the transported object. The axis of the roller 3 is consistent with the direction of the center line of the outer circle of the transported object, both being in the front-back direction. The component mounting structure includes a roller bracket mounting structure and a fastener connection structure. Both the roller bracket mounting structure and the fastener connection structure are formed by corresponding pins 5 and pin holes.

[0063] A pin hole is provided at each of the three corners of the triangular bracket 2. The two lower corners of the triangular bracket 2 extend between the two side plates 11 of the bracket 1. When the pin holes at the two lower corners of the triangular bracket 2 are aligned with the pin holes on the side plates 11, the pin 5 is inserted. The top of the triangular bracket 2 is provided with a groove to install the roller 3. The roller 3 is embedded in the top groove of the triangular bracket 2. When the pin hole on the roller 3 is aligned with the pin hole on the triangular bracket 2, the pin 5 is inserted. At this time, the upper outer cylindrical surface 3b of the roller is higher than the upper edge of the triangular bracket 2.

[0064] Combination Figure 1 When the first bracket pin hole 2a and the second bracket pin hole 2b on the two lower corners of the triangular bracket 2 are aligned with the third bracket pin hole 1c and the fourth bracket pin hole 1d on the side plate 11, the pin 5 is inserted to support the small irregular cross-section transport object 101. Pins 5 are inserted into the second bracket pin holes 1b at both ends of the bracket 1, and the two ends of the fastener 4 are installed onto the pins 5 in the second bracket pin holes 1b. The hooks at both ends of the fastener 4 can be used for hook connection, and the pull rope of the fastener 4 can be used to tighten the transport object, thus securing the small irregular cross-section transport object 101. The third bracket pin hole 1c and the fourth bracket pin hole 1d, along with the corresponding pins 5, constitute the roller bracket mounting structure, while the second bracket pin hole 1b and the corresponding pins 5 constitute the fastener connection structure.

[0065] Combination Figure 2 When the first bracket pin hole 1a and the second bracket pin hole 1b on the two lower corners of the triangular bracket 2 are aligned with the second bracket pin hole 1b and the third bracket pin hole 1c on the side plate 11, respectively, the large irregular cross-section transport object 102 can be supported. Pins 5 are inserted into the second bracket pin holes 1b at both ends of the bracket 1. The two ends of the fastener 4 are installed onto the pins 5 in the second bracket pin holes 1b. Hooks at both ends of the fastener 4 can be used for hook connection. The pull rope of the fastener 4 is used to tighten the transport object, thus securing the large irregular cross-section transport object 102. The second bracket pin holes 1b and the third bracket pin holes 1c, along with the corresponding pins 5, constitute the roller bracket mounting structure, and the second bracket pin holes 1b and the corresponding pins 5 constitute the fastener connection structure.

[0066] Figure 1 and Figure 2The transported items all have a cylinder and a protrusion located on the lower side of the cylinder, which makes the cross-section of the transported items irregular. The roller 3 is supported on the outer circumference of the cylinder, and the protrusion is located between two support units.

[0067] Combination Figure 3 and Figure 15 The fixing assembly shown in the diagram does not have a triangular bracket and consists of rollers 3 and fasteners 4. Rollers 3 support the outer circle of the transported object, and the axis of rollers 3 is aligned with the center line of the outer circle of the transported object. Fasteners 4 press the transported object onto rollers 3. The assembly installation structure includes a roller mounting structure and a fastener connection structure. There are two rollers 3, with a roller pin hole 3a in the center. The rollers 3 are installed between the two side plates 11 of the bracket 1, and the roller pin hole 3a on the roller 3 is aligned with the fourth bracket pin hole 1d on the side plate 11, or it can be the third bracket pin hole 1c. A pin 5 is inserted, and at this time, the upper outer cylindrical surface 3b of the roller is higher than the upper edge of the two side plates 11 of the bracket 1, which can support the circular cross-section transported object 103. The fasteners 4 are installed on the corresponding pins 5 in the second bracket pin hole 1b or the third bracket pin hole 1c on both sides of the bracket 1 to fasten the circular cross-section transported object 103. At this time, the fourth bracket pin hole 1d and the corresponding pin 5 constitute a roller mounting structure, and the second bracket pin hole 1b and the corresponding pin 5 constitute a bolt connection structure.

[0068] Combination Figure 4 and Figure 16 The fixing component shown in the diagram is not supported by rollers 3, but by a support beam 7. The fixing component includes a support beam 7 for supporting the transported item and a fastener 4 for pressing the transported item onto the support beam 7. The component mounting structure includes a support beam mounting structure. The support beam 7 includes a middle beam 72 and two end beams 71, which are fitted together with the middle beam 72 to form a telescopic structure. The middle beam 72 and end beams 71 are provided with locking structures to fix their relative positions. In other embodiments, the support beam can also be a single, integral structure.

[0069] The middle beam 72 of the support beam 7 is inserted into the end beam 71. The two ends of the middle beam 72 are provided with middle beam pin holes 72a. The spacing of the middle beam pin holes 72a at both ends is the same as the spacing of the two second bracket pin holes 1b on the bracket 1. The two end beams 71 are respectively fitted onto the two ends of the middle beam 72. Several end beam pin holes 71a are provided on the end beams 71 along the left and right directions. The two end beams 71 are moved so that the end beam pin holes 71a on the end beams 71 are aligned with the middle beam pin holes 72a on the middle beam 72. The support beam 7 is then embedded between the two side plates 11 of the bracket 1 so that the end beam pin holes 71a are aligned with the second bracket pin holes 1b of the side plates 11. The pin 5 is inserted to adjust the length of the support beam 7. The corresponding pin 5 and the pin hole form a locking structure. At this point, the upper surface of the end beam 71 is higher than the upper edge of the two side plates 11 of the bracket 1, which can support rectangular cross-section transport objects 104 of different widths. The two ends of the support beam 7 are provided with connecting seats on the two end beams 71. The grooves of the connecting seats are provided with pin holes on both sides for inserting pins 5 for installing the fasteners 4, thereby achieving the fastening of rectangular cross-section transport objects 104 of different widths. The pin holes 1b of the second bracket and the corresponding pins 5 constitute the support beam installation structure.

[0070] Combination Figure 5 , Figure 17 , Figure 18 The fixing components shown in the diagram include a bottom support and side supports. The bottom support consists of two rollers 3. The roller pin holes 3a are aligned with the fifth bracket pin holes 1e and are into which pins 5 are inserted. The fifth bracket pin holes 1e and their corresponding pins 5 constitute the roller mounting structure.

[0071] There are two side supports for supporting the transported object on the left and right sides respectively. The component mounting structure includes a roller mounting structure and a side support mounting structure. The side support is also known as the side support assembly, which includes a vertically extending upright 81 and a horizontally extending screw 82. The top of the upright 81 is provided with a threaded structure for threaded connection of the screw 82. The end of the screw 82 away from the upright 81 is connected to a side pressure head 83 through a ball joint. The side support mounting structure is used to fix the lower end of the upright 81, and the side pressure head 83 is used to press the screw 82 into the transported object in the left and right direction when it is screwed.

[0072] The lower part of the upright 81 is provided with two pin holes, namely the first upright pin hole 81b and the second upright pin hole 81c. The upright 81 extends between the two side plates 11 of the bracket 1, and when the two pin holes on the upright 81 are aligned with the first bracket pin holes 1a and the second bracket pin holes 1b at both ends of the side plate 11, the pin 5 is inserted to achieve the fixed connection between the side support assembly 8 and the bracket 1. The top of the upright 81 is provided with a threaded sleeve, which forms a threaded structure. The threaded hole of the threaded sleeve forms the threaded hole 81a of the upright. The threaded hole 81a of the upright rod mates with the external thread 82a of the screw rod 82. After mating, the upright rod 81 is perpendicular to the screw rod 82. One end of the screw rod 82 has an external thread 82a, and the other end has a ball head 82b. The ball head 82b mates with the ball socket 83a of the side pressure head 83. One side of the side pressure head 83 has a ball socket 83a, and the other side is a side support pressing surface 83b, which contacts the left and right sides of the side support and bottom support transport object 105. Rotating the screw rod 82 can adjust the lateral pressing force. The side support and bottom support transport object 105 refers to the left and right sides and bottom surface of the transport object that can only be supported. The first bracket pin hole 1a, the second bracket pin hole 1b, and the corresponding pin 5 constitute the side support mounting structure.

[0073] Each component of this transfer adapter assembly is simple, compact, and lightweight. Different modules can be quickly combined using pins to support and fix transfer objects with different cross-sections. The adapter has few models and specifications, is reliable in use, and is easy to store and manage.

[0074] This design creates a beam with a large root section and a small distal section, resulting in a beam of equal strength that can accommodate a wider range of circular and irregularly shaped cross-sections for transport, while also providing strong load-bearing capacity. When using rollers to support circular cross-section transport objects, the object can roll, facilitating posture adjustments.

[0075] By setting several pin holes on the long strip-shaped limiting strip fixed to the upper surface of the vehicle, the bracket can be installed at any position along the length of the vehicle to adapt to the support of different support positions of the transported object.

[0076] The bracket is placed on the upper surface of the limiting strip through the upper edge of the bracket frame cross section, which can easily realize the positioning of the bracket on the limiting strip and the insertion and removal of the pin.

[0077] A triangular bracket is used to provide transitional support for the transported object, resulting in a stable, compact structure with high load-bearing capacity. The use of nested inner and outer tube adjustable support beams can further expand the width of square-section transported objects.

[0078] The adjustable side support allows for stable transport and fixed support of objects that can be transported using both side and bottom supports.

[0079] Embodiments of the transfer vehicle of the present invention: The transfer vehicle includes a carrying platform and a transfer adapter assembly fixed on the carrying platform.
