Description

Technical Field

[0001] This invention relates to the field of logistics and transportation technology, and in particular to a mechanism for conveying and fixing large objects. Background Technology

[0002] Large object transportation refers to the transportation service of goods that meet one of the following conditions: (i) the external dimensions of the goods: the length is more than 14 meters, the width is more than 3.5 meters, or the height is more than 3 meters; (ii) the weight is more than 20 tons for single goods or non-separable group (bundle) goods. Under normal circumstances, road large object transportation should have super heavy-duty vehicle groups with an actual loading capacity of more than 20 tons and less than 100 tons for the whole large object, including tractor units and trailers (semi-trailers, concave low platform trailers), etc. The stability of the fixed large object transportation is particularly critical. For example, large objects with a height are easily tilted due to the overall instability of the center of gravity caused by vehicle turning, swaying, etc., which can easily cause traffic accidents and damage to the objects. Therefore, the fixing of large objects is very important.

[0003] In the prior art, patent publication number CN201660207U, titled "A Large Object Transport Support," relates to a transport support, belonging to the field of material storage and transportation. A large object transport support includes the large object, characterized by a support base, a column vertically mounted on the support base, and soft pads mounted perpendicularly to the column on both sides of the column on the base. Two large objects are placed on the soft pads and fixed between them using a connecting plate. Each object is fixed to the base using diagonal braces. This utility model's large object transport support has a compact structure, securely fixing the object to the support, ensuring a stable center of gravity, guaranteeing safety during transportation, and reducing transportation costs.

[0004] The aforementioned patent-style methods for securing large objects are quite common. Another method involves directly using ropes for support, but both suffer from instability. For example, in the patent, the support and the large object form a single unit, meaning their centers of gravity are also integrated. This makes them prone to shifting or tipping over when the vehicle turns or sways, especially for taller objects. Rope-based methods, due to rope strength limitations, cannot support heavy objects and are prone to causing transportation hazards due to instability. Furthermore, when transporting multiple sets of large objects, adjacent sets are prone to swaying and collisions within their designated space, leading to damage and economic losses, and also hindering stable securing. Therefore, to improve the situation in transporting large objects, a new large object conveying and securing mechanism needs to be designed. Summary of the Invention

[0005] The purpose of this invention is to provide a large object conveying and fixing mechanism to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A large object conveying and fixing mechanism of the present invention includes:

[0008] Loading base;

[0009] Side clamping plates, which are two sets arranged symmetrically on the loading base, are used to limit and fix large objects between the two sets of side clamping plates;

[0010] Pre-embedded anchors are fixed on the loading base. The pre-embedded anchors are symmetrically distributed in two sets on the loading base and are arranged one-to-one with the two sets of side clamping plates. Each set of pre-embedded anchors is provided with an inclined support rod supported on a set of side clamping plates at a close distance to it. Each set of side clamping plates is connected to a rope, and the rope passes around a large object and is connected to a set of pre-embedded anchors at a relatively far end of the side clamping plates.

[0011] And a gap-filling mechanism, which fills the gaps between two adjacent sets of large objects to prevent the large objects from shaking and bumping in the loading space.

[0012] Preferably, each set of side clamping plates includes a base fixed to the loading base and an upright plate connected to the base;

[0013] One end of the rope is connected to the upper end of the upright plate.

[0014] Preferably, a limiting block is provided on the side surface of the upright plate to limit the inclined support rod for support.

[0015] Preferably, the pre-embedded anchor is provided with a hanging ring, and the end of the rope away from the side clamping plate is provided with a hook corresponding to the hanging ring.

[0016] Preferably, the rope connecting the side clamping plate and the pre-embedded anchor is taut on the large object.

[0017] Preferably, two sets of the placement gap filling mechanisms are symmetrically arranged in the horizontal direction within the gap between two adjacent sets of large objects;

[0018] The placement gap filling mechanism is installed in the position between the two sets of side clamping plates located on the same side of the two sets of large objects that are fixedly placed adjacent to each other.

[0019] Preferably, the placement gap filling mechanism includes:

[0020] A filling body, wherein the filling body is provided with a fixing support mechanism for mounting on the side clamping plate;

[0021] The first top head consists of two sets symmetrically arranged on the filling body and extends out of the filling body to press against the two adjacent sets of large objects;

[0022] And a first clamping drive mechanism, which is disposed inside the filling body to drive two sets of the first mandrels to extend out of the filling body.

[0023] Preferably, the filling body is a hollow shell structure;

[0024] The fixed support mechanism includes side wing plates, which are two sets of symmetrically and vertically connected to the outer surface of the filling body. The two sets of side wing plates are connected one-to-one to the two sets of side clamping plates located on the same side of the two sets of large objects by bolts.

[0025] Preferably, the first clamping drive mechanism includes:

[0026] The first double-threaded screw has external threads symmetrically arranged at its two ends. The middle position of the first double-threaded screw is rotatably disposed inside the filling body via a bearing. The filling body has first square holes symmetrically opened on both sides of one end, allowing the first double-threaded screw to extend and simultaneously accommodating the first mandrel to extend into it. The first mandrel is a prism-shaped mandrel and corresponds to the shape of the first square hole so that the first mandrel cannot rotate within the first square hole. The end of the first mandrel that extends into the filling body has a first threaded hole. The first threaded hole accommodates the first double-threaded screw and engages with the thread so that when the first double-threaded screw rotates, the two sets of first mandrels move synchronously outward toward the filling body.

[0027] The first driven sprocket is coaxially sleeved on the middle position of the first double-threaded screw;

[0028] A first rotating shaft has one end extending into the filling body and is arranged parallel to the first double-threaded screw. The first rotating shaft is rotatably disposed in the filling body through a bearing.

[0029] The first drive sprocket is coaxially mounted on the first rotating shaft and located in the middle position inside the filling body;

[0030] And a first chain, which meshes with the first driving sprocket and the first driven sprocket.

[0031] Preferably, the first rotating shaft and the first double-threaded screw are located at the two ends of the filling body, and the first rotating shaft is located outside the gap between two adjacent sets of large objects;

[0032] A first insertion hole is provided at one end of the first rotating shaft that extends beyond the filling body.

[0033] The large object conveying and fixing mechanism provided by the present invention, as described above, has the following beneficial effects:

[0034] Firstly, this device stabilizes the center of gravity of large objects using two sets of side clamping plates, and reinforces this stability with inclined support rods connected to pre-embedded anchors. Then, ropes are installed on the side clamping plates and connected to pre-embedded anchors on the opposite side, allowing the large object to be secured with tension. This provides a triple-stabilizing effect for the large object. More importantly, when the large object tilts, in addition to the support from the side clamping plates and inclined support rods in the tilting direction, the pre-embedded anchors on the opposite side of the tilt direction further strengthen the stabilizing and supporting effect of the side clamping plates in the tilting direction through the ropes. Simultaneously, the pre-embedded anchors in the tilting direction... While the inclined support rod reinforces the side clamping plate on the same side, it can also be pulled by the side clamping plate on the opposite side through the connection of ropes, further improving its fixing stability and strengthening the support stability of the side clamping plate on the same side. Therefore, when the center of gravity of a large object tilts, the above four fixing effects provide stable support, making the large object more stable during transportation. At the same time, the gap filling mechanism fills the gap between two adjacent sets of large objects to prevent the large objects from shaking and bumping in the loading space, further improving the fixing stability of large objects and reducing the shaking and bumping incidents between objects.

[0050] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0051] Please see Figure 1-12 A large object conveying and fixing mechanism, comprising:

[0052] The loading base 1 serves as a load-bearing base for loading large objects. It can be used as a cargo box of a transport vehicle, or it can be directly fixed to the cargo box, and then the large objects can be fixed with this device.

[0053] The side clamping plates are two sets that are symmetrically distributed on the loading base 1 to limit and fix large objects between the two sets of side clamping plates. That is, each time a large object is loaded, it is clamped and fixed by two sets of symmetrical side clamping plates, which plays a role in stabilizing and supporting the two sides of the goods.

[0054] Anchor nails 2 are embedded and fixed on the loading base 1. The anchor nails 2 are symmetrically distributed in two sets on the loading base 1 and are set one-to-one with the two sets of side clamping plates. Each set of anchor nails 2 is provided with an inclined support rod 3 supported on a set of side clamping plates at a close distance to it. Each set of side clamping plates is connected to a rope 4, and the rope 4 passes around a large object and is connected to a set of anchor nails 2 at a relatively far distance from the side clamping plate.

[0055] And a gap-filling mechanism, which fills the gap between two adjacent sets of large objects to prevent the large objects from shaking and bumping in the loading space, that is, to avoid shaking between the goods by reducing the shaking space between the goods.

[0056] In summary, this device first stabilizes the center of gravity of large objects using two sets of side clamping plates, and then reinforces them with inclined support rods 3 connected to pre-embedded anchors 2. Furthermore, by installing ropes 4 on the side clamping plates and connecting them to the pre-embedded anchors 2 on the opposite side, the large objects can be secured by the ropes 4. This provides a triple-fixing effect for large objects. More importantly, when the center of gravity of the large object tilts, it is not only supported by the side clamping plates and inclined support rods 3 in the tilting direction, but also by the pre-embedded anchors 2 on the opposite side of the tilting direction, which, through the ropes 4, further strengthen the stabilizing and supporting effect of the side clamping plates in the tilting direction. The pre-embedded anchor 2 reinforces the side clamping plate on the same side through the inclined support rod 3, and can also be pulled by the side clamping plate on the opposite side through the connection of the rope 4, further improving its fixing stability and further strengthening the support stability of the side clamping plate on the same side. Therefore, when the center of gravity of a large object tilts, the above four fixing effects provide stable support, making the large object more stable during transportation. At the same time, the gap filling mechanism fills the gap between two adjacent sets of large objects to prevent the large objects from shaking and bumping in the loading space, further improving the fixing stability of the large objects and reducing the shaking and bumping events between objects.

[0057] Furthermore, each set of side clamping plates includes a base 5 fixed on the loading base 1 and an upright plate 6 connected to the base 5. The base 5 and the upright plate 6 form an L-shape. The base 5 is connected to the loading base 1 to support the upright plate 6, so that the upright plate 6 can be placed against the cargo to support the cargo.

[0058] One end of rope 4 is connected to the upper end of upright plate 6.

[0059] Furthermore, a limiting block 8 is provided on the side surface of the upright plate 6 to support the inclined support rod 3. That is, in order to ensure that the upper end of the inclined support rod 3 can be supported on the upright plate 6 without slipping, or the limiting block 8 can be replaced with a limiting groove structure that allows the upper end of the inclined support rod 3 to extend into.

[0060] Furthermore, the pre-embedded anchor 2 is equipped with a hanging ring 9, and the end of the rope 4 away from the side clamping plate is equipped with a hook 10 corresponding to the hanging ring 9, so that the rope 4 can be directly attached to the hanging ring 9 for connection via the hook 10. The hanging ring 9 and the pre-embedded anchor 2 can be connected by a threaded rod or other structure, so that when the threaded rod supports the hanging ring 9, the height of the hanging ring 9 can be adjusted by rotating the threaded rod and the pre-embedded anchor 2 to adjust the tension of the rope 4, so as to more stably tighten the goods.

[0061] Furthermore, the rope 4 connecting the side clamping plate and the pre-embedded anchor 2 is taut on the large object to more stably pull the cargo.

[0062] Furthermore, two sets of gap-filling mechanisms are symmetrically arranged in the horizontal direction in the gap between two adjacent sets of large objects. Specifically, multiple sets of gap-filling mechanisms can be set at different heights on each side as needed to provide more stable support.

[0063] Among them, the position between the two sets of side clamping plates located on the same side of the two sets of large objects is used to install the placement gap filling mechanism.

[0064] Furthermore, the gap-filling mechanism includes:

[0065] The filling body 11 is provided with a fixing support mechanism for mounting on the side clamping plate;

[0066] The first top head 12 is two sets symmetrically arranged on the filling body 11 and extends out of the filling body 11 to press against the two adjacent sets of large objects;

[0067] And a first clamping drive mechanism, which is located inside the filling body 11 to drive two sets of first top heads 12 to extend out of the filling body 11, so that the filling body 11 extends out and clamps between two adjacent sets of large objects to achieve the effect of filling space.

[0068] Furthermore, the filling body 11 is a hollow shell structure;

[0069] The fixed support mechanism includes side wing plates 13. The side wing plates 13 are two sets that are symmetrically and vertically connected to the outer surface of the filling body 11. The two sets of side wing plates 13 are connected one-to-one to the two sets of side clamping plates located on the same side of the two sets of large objects by bolts.

[0070] Furthermore, the first clamping drive mechanism includes:

[0071] The first double-threaded screw 14 has external threads symmetrically arranged at its two ends. The middle position of the first double-threaded screw 14 is rotatably set inside the filling body 11 through a bearing. The filling body 11 has first square holes 15 symmetrically opened on both sides of one end, allowing the first double-threaded screw 14 to extend and simultaneously accommodating the first head 12. The first head 12 is a prism-shaped head and corresponds to the shape of the first square hole 15 so that the first head 12 cannot rotate in the first square hole 15. The end of the first head 12 that extends into the filling body 11 has a first threaded hole 16. The first threaded hole 16 accommodates the first double-threaded screw 14 and performs threaded engagement so that when the first double-threaded screw 14 rotates, the two sets of first heads 12 move synchronously outward from the filling body 11.

[0072] The first driven sprocket 17 is coaxially sleeved on the middle position of the first double-threaded screw 14;

[0073] The first rotating shaft 18 has one end extending into the filling body 11 and is arranged parallel to the first double-threaded screw 14. The first rotating shaft 18 is rotatably arranged in the filling body 11 through a bearing.

[0074] The first drive sprocket 19 is coaxially sleeved on the first rotating shaft 18 and located in the middle position inside the filling body 11;

[0075] And a first chain 20, which meshes with a first driving sprocket 19 and a first driven sprocket 17.

[0076] Specifically, the first rotating shaft 18 is driven to rotate, so as to drive the first double-threaded screw 14 to rotate through the meshing transmission between the first driving sprocket 19, the first driven sprocket 17 and the first chain 20. Because the thread direction of the double threads of the first double-threaded screw 14 is set, it can simultaneously drive the two sets of first mandrels 12 to move outward toward the outside of the filling body 11 when the first double-threaded screw 14 rotates.

[0077] Furthermore, the first rotating shaft 18 and the first double-threaded screw 14 are respectively located at the two ends of the filling body 11, and the first rotating shaft 18 is located outside the gap between two adjacent sets of large objects, so that the first rotating shaft 18 can be easily operated from the outside.

[0078] The first shaft 18 has a first insertion hole 21 at one end that extends beyond the filling body 11, so that the first shaft 18 can be driven to rotate in a more effortless manner by inserting a lever into the first insertion hole 21.

[0079] In another embodiment of the large object conveying and fixing mechanism disclosed in this invention, see [link to relevant documentation]. Figure 1 , 2 3. In order to facilitate matching the size of large objects, in the case of small size differences, after the latter has placed the goods between the two sets of side clamping plates, it is necessary to press the side clamping plates closer to the goods to stabilize and hold the goods. In this embodiment, the two sets of symmetrically arranged side clamping plates can adjust the spacing to match. A width adjustment mechanism is provided between the side clamping plates and the loading base 1.

[0080] Furthermore, the width adjustment mechanism includes a support and guide mechanism for supporting and guiding the movement of the side clamping plate, and a width adjustment drive mechanism for driving the movement of the side clamping plate.

[0081] Furthermore, the support and guide mechanisms consist of two identical sets symmetrically distributed parallel to each other below the side clamping plates. Each set of support and guide mechanisms includes:

[0082] The first assembly groove 22 is formed on the upper surface of the loading base 1, and the extending direction of the first assembly groove 22 is the same as the moving direction of the side clamping plate.

[0083] The guide support rod 23 is horizontally fixed in the first assembly groove 22 along the extension direction of the first assembly groove 22.

[0084] And support rings 24, which are two sets of the base 5 connected to the side clamping plate near the two side edges on the lower surface. Both sets of support rings 24 are sleeved on the guide support rod 23 and slide on the guide support rod 23.

[0085] Specifically, four sets of support rings 24 from the two sets of support and guiding mechanisms are used to support the entire side clamping plate at the four corners of the lower surface of the base 5. The support rings 24 slide on the guide support rods 23 to guide the direction of movement. Therefore, the guide support rods 23 and support rings 24 need to have sufficient support strength to stabilize the side clamping plate. Specifically, this can be achieved by setting guide support rods 23 and support rings 24 with larger diameters and thicknesses and using high-strength materials.

[0086] Furthermore, the width adjustment drive mechanism includes:

[0087] The second assembly groove 25 is formed on the upper surface of the loading base 1, and the extension direction of the second assembly groove 25 is the same as the movement direction of the side clamping plate.

[0088] The threaded rod 26 is rotatably mounted in the second mounting groove 25 via a bearing. The threaded rod 26 is arranged parallel to the guide support rod 23. One end of the threaded rod 26 extends out of the loading base 1 from the second mounting groove 25. The threaded rod 26 can be easily driven to rotate by a handle or other structure that can be provided to turn the threaded rod 26.

[0089] And the first nut pair 27, which is coaxially sleeved on the threaded rod 26 and threadedly engaged with the threaded rod 26, with the outer surface of the first nut pair 27 connected to the center position of the lower surface of the base 5.

[0090] Specifically, by rotating the threaded rod 26, it engages with the first nut pair 27 through a threaded connection, driving the first nut pair 27 to move along the extension direction of the threaded rod 26. This, in turn, moves the base 5 in the side clamping plate. At this time, the support and guide mechanism assists in guiding the movement of the side clamping plate, thereby adjusting the distance between the two sets of side clamping plates. This allows for the fixing of goods with small size differences, or, after placing the goods between the two sets of side clamping plates, adjusting the spacing to bring the side clamping plates closer to the goods to stabilize and support them, thus providing better and more stable support.

[0091] In another embodiment of the large object conveying and fixing mechanism disclosed in this invention, see [link to relevant documentation]. Figure 4 , 5 To ensure that the placement gap filling mechanism can stably fill and support the two adjacent sets of large objects, it is first necessary to stabilize and fix the placement gap filling mechanism between the two sets of side clamping plates in order to stabilize the two sets of large objects and reduce or limit shaking. Therefore, in order to further stabilize and fix the placement gap filling mechanism, an outward expansion fixing mechanism is set on the placement gap filling mechanism.

[0092] Furthermore, the externally extending fixing mechanism includes:

[0093] The second top head (28) is two sets symmetrically arranged on the filling body (11) and extends out of the filling body (11) to press against the two sets of upright plates (6) in the two adjacent sets of side support plates;

[0094] And a second clamping drive mechanism, which is disposed inside the filling body (11) to drive two sets of second mandrels (28) to extend out of the filling body (11).

[0095] Furthermore, the second clamping drive mechanism includes:

[0096] The second double-threaded screw (29) has external threads symmetrically arranged at its two ends. The middle position of the second double-threaded screw (29) is rotatably set inside the filling body (11) through a bearing. The filling body (11) has two symmetrical square holes (30) on both sides of one end opposite to the position of the first double-threaded screw (14) to allow the second double-threaded screw (29) to extend and to accommodate the second mandrel (28) to extend into. The second mandrel (28) is a prismatic mandrel and corresponds to the shape of the second square hole (30) so that the second mandrel (28) cannot be inserted into the first double-threaded screw (14). Rotating within the square hole (30), the second head (28) extends into the filling body (11) and has a second threaded hole (31) at one end. The second threaded hole (31) accommodates the second double threaded screw (29) to extend in and engage with the thread so that when the second double threaded screw (29) rotates, the two sets of second heads (28) move outwards towards the filling body (11) simultaneously, so that the filling body (11) can be further fixed and supported by the two second heads (28) pressing against the two sets of upright plates (6) in the two sets of adjacent side support plates.

[0097] The second driven sprocket (32) is coaxially sleeved on the middle position of the second double-threaded screw (29);

[0098] The second rotating shaft (33) has one end extending into the filling body (11) and is arranged parallel to each other with the second double threaded screw (29). The second rotating shaft (33) is rotatably arranged in the filling body (11) through a bearing.

[0099] The second drive sprocket (34) is coaxially mounted on the second rotating shaft (33) and located in the middle position inside the filling body (11);

[0100] And a second chain (35), which meshes with a second driving sprocket (34) and a second driven sprocket (32).

[0101] The diameters of the second driven sprocket (32) and the second driving sprocket (34) should be smaller than the diameters of the first driven sprocket (17) and the first driving sprocket (19) so that the second driven sprocket (32) and the second driving sprocket (34) and the second chain (35) meshing with them can be installed inside the first chain (20) to make reasonable use of the internal space of the filling body (11).

[0102] Specifically, in actual operation, the second drive sprocket (34) is driven to rotate by rotating the second shaft (33), and then driven by the second chain (35), the second driven sprocket (32) and the second double-threaded screw (29) are rotated. Then, the threaded engagement between the second double-threaded screw (29) and the internal threads of the two sets of second mandrels (28) is used to drive the two sets of second mandrels (28) to move along the extension direction of the axis of the second double-threaded screw (29), so as to further fix and support the filling body (11) by extending out of the filling body (11) and pressing it between the two sets of upright plates (6).

[0103] A third insertion hole (36) is provided at one end of the second rotating shaft (33) that extends out of the filling body (11) so that a lever can be inserted through the third insertion hole (36) so that the second rotating shaft (33) can be driven to rotate with less effort.

[0104] In another embodiment of the large object conveying and fixing mechanism disclosed in this invention, see [link to relevant documentation]. Figure 2 , 5 The 6-position gap filling mechanism uses a first head (12) with a smaller diameter to expand outward to press against the gap between two sets of large objects. However, in the case of goods or packaging with weaker resistance to compression, it is necessary to increase the contact area against the goods to avoid damage to the goods or packaging caused by the compression force. Therefore, it is necessary to add an external elastic contact plate to the first head (12) to increase the contact area with the goods or packaging while also having a certain contact elasticity to avoid damage to the goods or packaging caused by rigid impact.

[0105] Furthermore, the external resilient contact plate includes an external plate (37) and a resilient mounting mechanism for connecting the external plate (37) to the end of the first head (12);

[0106] Furthermore, the flexible mounting mechanism includes:

[0107] A receiving groove (38) is formed on the side surface of the outer plate (37) and is capable of receiving the end of the first head (12) extending into it;

[0108] A compression spring (39) is provided in the receiving groove (38). A pressure plate (40) is connected to one end of the compression spring (39) facing the outside of the receiving groove (38). The pressure plate (40) is used to contact the end of the first top head (12) that extends into the receiving groove (38).

[0109] The third threaded hole (41) is two sets symmetrically opened on both sides of the outer plate (37), and the two sets of third threaded holes (41) are connected to the receiving groove (38);

[0110] The limiting screw (42) is provided in two sets corresponding to the two sets of third threaded holes (41). The limiting screw (42) passes through the third threaded hole (41) and is threadedly engaged with the third threaded hole (41). The limiting screw (42) extends into the receiving groove (38).

[0111] And the movement distance limiting groove (43) is symmetrically opened in two groups at the end of the first top head (12) and is set one-to-one with the two groups of limiting screws (42). After the limiting screw (42) extends into the receiving groove (38), it will limit the outer plate (37) from leaving the first top head (12) by extending into the movement distance limiting groove (43).

[0112] During the shock absorption process via the compression spring (39), the compression spring (39) is compressed. At this time, the limiting screw (42) slides in the moving distance limiting groove (43), so that this structure not only restricts the outer plate (37) from disengaging from the first top head (12), but also has the functions of moving guide and limiting the distance of the first top head (12) extending into the receiving groove (38).

[0113] Specifically, during operation, the first pusher (12) is inserted into the receiving groove (38) and pressed against the pressure plate (40) to compress the compression spring (39). At this time, the two sets of limiting screws (42) are turned to extend into the movement distance limiting groove (43) to prevent the outer plate (37) from detaching from the first pusher (12). At this time, the outer plate (37) with a large contact area contacts the goods, avoiding damage to the goods.

[0114] In another embodiment of the large object conveying and fixing mechanism disclosed in this invention, see [link to relevant documentation]. Figure 1 , 7 8 and 9, when facing vehicle turns or sudden braking, the overall center of gravity is prone to shift, tipping, or forward inertia, leading to unstable cargo and collision with the vehicle's cab. Furthermore, securing objects using ropes is insufficient due to rope strength limitations, unable to withstand the inertia of large, heavy objects, easily causing transportation hazards due to unstable securing. Therefore, in this embodiment, a large object conveying and securing mechanism also includes an inertial movement direction guiding mechanism, which includes:

[0115] Fixed base 63, so that loading base 1 is mounted on fixed base 63;

[0116] Side barriers are set on fixed base 63 to limit the sides of large objects, and a gap is left in the direction of the large object facing the cab of the logistics transport vehicle.

[0117] The movable guide plate 44 is vertically set on the fixed base 63 to block the gap formed by the side enclosure. One side of the movable guide plate 44 is rotatably connected to the fixed base 63 with the longitudinal axis as the rotation axis, so that when the fixed base 63 and the goods are impacted, one end is knocked open and the other end rotates, so as to guide the goods to deviate from the initial movement direction.

[0118] The intelligent limiting structure is used to limit the moving guide plate 44 to the position of the gap in the fence side and release the limit on the moving guide plate 44 when the load of the fence is exceeded. The pressure sensor is used to detect the force, and the corresponding judgment can be made in time to achieve the effect of intelligent response and realize the high efficiency and accuracy of the device operation.

[0119] And the movable guide position limiting block 45 is fixed on the fixed base 63. When the movable guide plate 44 rotates to guide large objects to move away from the driver's cab of the logistics transport vehicle, the movable guide plate 44 abuts against the movable guide position limiting block 45. That is, the movable guide position limiting block 45 plays the role of the main load-bearing part for changing the direction of movement of goods.

[0120] Furthermore, the side enclosure includes a first baffle 46 enclosing the side opposite to the movable guide plate 44, a second baffle 47 located on one of the adjacent sides of the movable guide plate 44 and between the movable guide plate 44 and the first baffle 46, and a third baffle 48 located on the side opposite to the second baffle 47, wherein the third baffle 48 is a discontinuously distributed set of baffles.

[0121] The first baffle 46, the second baffle 47 and the third baffle 48 are all fixedly mounted on the fixed base 63.

[0122] Specifically, the first baffle 46 and the second baffle 47 provide stronger support and containment for the cargo than the third baffle 48. Furthermore, the third baffle 48 consists of multiple discontinuously distributed sets. When the impact force exceeds an uncontrollable critical value, the third baffle 48 will be broken by the cargo in the direction of movement.

[0123] Furthermore, the moving guide plate 44 is provided with a moving guide auxiliary mechanism to reduce the frictional resistance between the moving guide plate 44 and large objects, so as to guide the movement direction of the goods more smoothly and avoid the situation that it is difficult to change the movement direction due to excessive friction between the goods and the moving guide plate 44 under stamping.

[0124] Furthermore, the mobile guidance assistance mechanism includes:

[0125] Guide chute 49, which is a plurality of sets formed on the side surface of the moving guide plate 44 facing the large object;

[0126] A sliding plate 50 is embedded in a guide groove 49 and can slide within the guide groove 49. Multiple sets of connecting posts 51 are evenly distributed between the sliding plate 50 and the inner surface of the guide groove 49.

[0127] And an anti-slip mat 52, which is laid on the side surface of the sliding plate 50 facing the large object.

[0128] Specifically, the anti-slip mat 52 is made of materials such as rubber mats, which not only have a cushioning effect but also anti-slip properties. When the impact force exceeds an uncontrollable critical value, it drives the sliding plate 50 to move and break multiple sets of connecting columns 51, thereby causing the sliding plate 50 to slide in the guide groove 49, so as to guide the goods to deviate from the original direction of movement more smoothly and reduce the probability of heavy goods breaking or deforming the moving guide plate 44.

[0129] Furthermore, the intelligent limiting structure includes a telescopic limiting body 53, which is telescopically mounted on the fixed base 63. The telescopic limiting body 53 can be telescopically moved on the fixed base 63 by an electrically controlled telescopic rod mounted on the fixed base 63.

[0130] A pressure sensor 54 is provided on the side surface of the telescopic limiting body 53 facing the moving guide plate 44.

[0131] Specifically, the telescopic limiter 53 can be raised and lowered by telescopic drive components such as an electrically controlled telescopic rod or a telescopic cylinder. When the pressure sensor 54 detects that the impact force exceeds an uncontrollable critical value, the telescopic limiter 53 is driven by the electrically controlled telescopic rod or other telescopic drive components to retract below the fixed base 63, releasing the moving guide plate 44. Supported by the moving guide position limit block 45, this allows the guide plate to guide the inertial moving goods and loading base 1 in an inclined state, changing their direction of movement and preventing collisions with the vehicle cab, thus improving the safety of cargo transportation. To improve the response speed of the telescopic limiter 53, it can be set to protrude only a limited distance from the loading base 1, such as less than 10cm. Furthermore, a storage spring can be used for assistance. For example, a storage spring can be compressed at the top of the telescopic limiter 53, and a limit structure can limit the storage spring. When unlocking is needed, the limit structure disengages from the storage spring, and the instantaneous release of the storage spring compresses the telescopic limiter 53, thus ensuring instantaneous triggering when required.

[0132] The electrical connections and control of the electrical components involved in this device are common knowledge well known to those skilled in the art, and will not be elaborated upon here. For example, the pressure sensor 54 and the electrically controlled telescopic rod can be programmed and controlled by controllers or other control components.

[0133] In another embodiment of the intelligent auxiliary device for logistics transportation disclosed in this invention, see [link to relevant documentation]. Figure 1 , 1011, 12. The inertial movement direction guiding mechanism can change the guiding method of the loading base 1 and large objects according to the specific goods. For example, for goods that are high and need to be prevented from tipping over, the inertial movement direction guiding mechanism described above is used to move them away from the vehicle cab to avoid a traffic accident. For goods that do not need to be prevented from tipping over, and considering the need to avoid the impact on other vehicles on the road, in this embodiment, the inertial movement direction guiding mechanism guides the loading base 1 and large objects near the vehicle cab upwards, that is, in the form of raising the loading base 1 and large objects in the direction of movement, so as to guide the loading base 1 and large objects to avoid impacting the vehicle cab.

[0134] Furthermore, the inertial movement direction guidance mechanism in this embodiment includes:

[0135] Support arms 55 are two sets of identical structures and are symmetrically arranged on both sides of the loading base 1 near the end of the vehicle cab. One end of the support arm 55 is rotatably connected to the loading base 1 with an axis perpendicular to the side surface of the loading base 1, and the other end can rotate with this axis.

[0136] First support part and second support part, each set of support arms 55 is provided with a first support part and a second support part. The first support part is provided on the side surface of the loading base 1 on the same side as the support arm 55. When the support arm 55 rotates in the opposite direction of the vehicle's travel direction, it is restricted from rotating when it reaches the first support part. The second support part is provided on the fixed base 63 on the same side as the support arm 55. When the support arm 55 swings in the direction of the vehicle's travel direction, it is restricted from rotating when it reaches the second support part.

[0137] And side limiting blocks 56, which are two sets of blocks symmetrically distributed on both sides of the loading base 1 and set on the fixed base 63, are used to limit the sliding of the loading base 1 in the direction of vehicle travel to improve the stability of fixing the loading base 1.

[0138] Furthermore, an overlapping shaft 57 is provided at the swinging end of the support arm 55;

[0139] Furthermore, the first support part includes a first overlapping block 58, which is disposed on the side surface of the loading base 1 on the same side as the support arm 55. The upper surface of the first overlapping block 58 is provided with a first overlapping groove 59. When the support arm 55 swings to the first overlapping block 58, the overlapping shaft 57 overlaps in the first overlapping groove 59. At this time, the overlapping shaft 57 overlaps in the first overlapping groove 59 to suspend the support arm 55 when the equipment is idle. At this time, it does not affect the loading base 1 from being loaded, unloaded or moved on the fixed base 63.

[0140] Furthermore, the second support includes a second overlapping block 60, which is disposed on a fixed base 63 on the same side as the support arm 55. A second overlapping groove 61 is provided on the upper surface of the second overlapping block 60. When the support arm 55 swings to the second overlapping block 60, the overlapping shaft 57 overlaps in the second overlapping groove 61.

[0141] Specifically, when using this device to secure and transport goods, after securing the goods, or before securing the goods, the support arm 55 is swung to the second overlapping block 60, causing the overlapping shaft 57 to overlap within the second overlapping groove 61. At this time, the support arm 55 is in an inclined state, and the height of the end connected to the loading base 1 is higher than the height of the end connected to the fixed base 63. Therefore, under the limiting effect of the second overlapping groove 61 on the overlapping shaft 57, whether the loading base 1 moves backward or forward relative to the fixed base 63, the limiting effect between the second overlapping groove 61 and the overlapping shaft 57 further secures the loading base 1. This is one of the functions of the support arm 55.

[0142] In addition, when the vehicle brakes suddenly, because the loading base 1 and the goods fixed on it cannot be secured due to inertia, the loading base 1 will slide onto the fixed base 63 (here, the fixed base 63 is set not to slide on the vehicle, but the loading base 1 needs to be able to slide onto the fixed base 63, which can be set by the fixing method or the deviation of friction). At this time, because the support arm 55 is tilted and under the support limit of the second support part, the support arm 55 will rotate around the overlapping shaft 57 as the axis. Then, during the rotation, it will support the front end of the loading base 1, that is, achieve the effect of raising the front end of the loading base 1, which will guide the movement of the loading base 1 and the goods, and prevent the loading base 1 and the goods from rushing into the cab and posing a life threat to the driver, and also prevent the loading base 1 and the goods from rushing to the sides of the vehicle and affecting other vehicles.

[0143] In another embodiment of the intelligent auxiliary device for logistics transportation disclosed in this invention, see [link to relevant documentation]. Figure 1 , 7 8, 9. A moving distance limiting traction rope 62 is provided on the fixed base 63. The other end of the moving distance limiting traction rope 62 is connected to the front end position of the loading base 1 in the moving direction. In addition to limiting the distance of the loading base 1 in the inertial moving direction by the moving distance limiting traction rope 62, it can also guide and limit the rotation angle of the support arm 55 in the inertial moving direction guiding mechanism based on the moving distance of the loading base 1, so as to prevent the support arm 55 from rotating more than 90 degrees and failing to play the role of supporting the loading base 1 and the lifting of large objects.

[0144] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
