[0001] This application relates to the field of transport vehicle technology, specifically to a folding bridge device and a transport vehicle. Background Technology
[0002] During the process of transporting goods from the ground to the vehicle, a bridging device needs to be erected between the vehicle and the ground to assist in the transportation of goods. Some bridging devices have fixed dimensions and an excessively large angle with the ground, which only slightly improves the passage of goods. Some bridging devices adopt a folding design, which reduces the angle with the ground, but has the problems of short service life and high safety risks. Utility Model Content
[0003] The purpose of this application is to overcome the above-mentioned technical deficiencies and propose a folding bridge crossing device and a transport vehicle to solve the technical problem that bridge crossing devices in the known technology cannot simultaneously improve transport passability and safety.
[0004] To achieve the above-mentioned technical objectives, this application adopts the following technical solution:
[0005] In a first aspect, this application provides a folding bridge device, including a mounting base, a first carrier, a second carrier, a first connector, a second connector, and a first drive member. The mounting base is used to connect to a vehicle body. One end of the first carrier is rotatably connected to the mounting base. One end of the second carrier is rotatably connected to the other end of the first carrier, and the other end of the second carrier is used to abut against the ground. The second carrier has a folded position that conforms to the first carrier and a working position parallel to the first carrier. One end of the first connector is rotatably connected to the first carrier. One end of the second connector is rotatably connected to the second carrier, and the other end of the second connector is rotatably connected to the first connector via a first pivot. One end of the first drive member is movably connected to the first carrier, and the other end of the first drive member is driveably connected to the first pivot. The first drive member is used to drive the first pivot to move, thereby driving the second carrier to rotate relative to the first carrier between the folded position and the working position.
[0006] In some embodiments, the first carrier has a first extension that extends obliquely toward the second carrier, and the first connector is rotatably connected to the first extension; the second carrier has a second extension that extends obliquely toward the first carrier, and the second connector is rotatably connected to the second extension.
[0007] In some embodiments, the second connector has a receiving hole, and when the second carrier is in the folded position, the end of the first connector near the second connector is received in the receiving hole.
[0008] In some embodiments, the first support member includes two first longitudinal beams, a plurality of first transverse beams, and a plurality of first support plates; the two first longitudinal beams are spaced apart along the length direction of the first transverse beams, the plurality of first transverse beams are spaced apart between the two first longitudinal beams along the length direction of the first longitudinal beams, the two ends of the plurality of first transverse beams are respectively connected to the two first longitudinal beams, and a first support plate is provided between two adjacent first transverse beams; the first connector is rotatably connected to the middle part of a first transverse beam.
[0009] In some embodiments, the second support member includes two second longitudinal beams, a plurality of second transverse beams, and a second support plate; the two second longitudinal beams are spaced apart along the length direction of the second transverse beams, the plurality of second transverse beams are spaced apart between the two second longitudinal beams along the length direction of the second longitudinal beams, the two ends of the plurality of second transverse beams are respectively connected to the two second longitudinal beams, and the second support plate is disposed on the plurality of second transverse beams; the second connector is rotatably connected to the middle part of one of the second transverse beams.
[0010] In some embodiments, the first carrier has a first bearing surface, the second carrier has a second bearing surface, a first connecting portion is formed at the end of the first carrier away from the first bearing surface, and a second connecting portion is formed at the end of the second carrier away from the second bearing surface. The second connecting portion extends toward the first carrier, and the portion of the second connecting portion extending out of the second carrier is rotatably connected to the first connecting portion, so that when the second carrier rotates to the point where the second bearing surface is coplanar with the first bearing surface, it abuts against the first carrier.
[0011] In some embodiments, the folding bridge device further includes: a base for connecting to a vehicle body; a second drive member rotatably connected to the base, the other end of the second drive member being rotatably connected to the first support member, the second drive member being used to drive the second support member to rotate relative to the mounting base.
[0012] In some embodiments, the first carrier has a mating portion formed at one end near the mounting base, and a mating groove is formed on the side of the mating portion near the second drive member. The mounting base includes a second pivot, which is mated in the mating groove. The second drive member is drively connected to the mating portion and is configured to drive the mating portion to rotate about the second pivot.
[0013] In some embodiments, the first support member includes a first crossbeam and two spaced-apart first longitudinal beams, with the two ends of the first crossbeam respectively connected to the two first longitudinal beams, and the mating part connected to the first crossbeam; the mounting base also includes a base body disposed between the two first longitudinal beams, with a second pivot rotatably passing through the base body, and the two ends of the second pivot rotatably connected to the two first longitudinal beams.
[0014] Secondly, this application also provides a transport vehicle, including a vehicle body and the aforementioned folding bridge device, wherein the mounting base of the folding bridge device is fixedly connected to the vehicle body.
[0015] Compared to known technologies, the folding bridge device provided in this application allows the first load-bearing member to rotate relative to the mounting base onto the vehicle body when the transport vehicle does not require crossing the bridge. Simultaneously, the second load-bearing member rotates to a folded position under the drive of the first drive member, thereby reducing the required storage size of the folding bridge device. When the transport vehicle needs to transport goods, the first drive member drives the first pivot to move. During the movement of the first pivot, the first connecting member rotates relative to the first load-bearing member, and simultaneously drives the second connecting member to rotate relative to the second load-bearing member. Since the position of the first load-bearing member remains stationary at this time, the first drive member also moves synchronously relative to the first load-bearing member. This applies a force to the second load-bearing member in a direction away from the first load-bearing member through the second connecting member, causing the second load-bearing member to rotate relative to the first load-bearing member. Thus, through the action of the first drive member, the second load-bearing member can be driven to rotate to a working position parallel to the first load-bearing member. This significantly extends the overall length of the folding bridge device, thereby reducing the angle between the folding bridge device and the ground, and improving the transportability of goods. Meanwhile, when the second load-bearing component is in the working position, the first connecting component can support the first load-bearing component, and the second connecting component can support the second load-bearing component, enabling the folding bridge device to carry goods more stably. This further improves the operational safety of the folding bridge device. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0030] To address the technical problem that existing bridge crossing devices cannot simultaneously improve both transport passability and safety, this application provides a folding bridge crossing device and a transport vehicle, which can improve both transport passability and safety.
[0031] It should be noted that the folding bridge device of this application is used in, but not limited to, transport vehicles, etc. For the sake of explanation, this application only uses the application of the folding bridge device in a transport vehicle as an example. The principle of the folding bridge device in other types of equipment is essentially the same as that in the transport vehicle, and will not be described in detail here.
[0032] Please see Figures 1 to 5 The folding bridge device 10 includes a mounting base 11, a first support member 12, a second support member 13, a first connector 14, a second connector 15, and a first drive member 17. The mounting base 11 is used to connect to the vehicle body 20. One end of the first support member 12 is rotatably connected to the mounting base 11. One end of the second support member 13 is rotatably connected to the other end of the first support member 12, and the other end of the second support member 13 is used to abut against the ground 30. The second support member 13 has a folding position that conforms to the first support member 12 and a working position parallel to the first support member 12. One end of the first connector 14 is rotatably connected to the first support member 12. One end of the second connector 15 is rotatably connected to the second support member 13, and the other end of the second connector 15 is rotatably connected to the first connector 14 via a first pivot 16. One end of the first drive member 17 is movably connected to the first support member 12, and the other end of the first drive member 17 is drively connected to the first pivot 16, thereby driving the second support member 13 to rotate relative to the first support member 12 between the folding position and the working position.
[0033] According to the folding bridge device 10 of this embodiment, see Figure 1 In transport vehicle 1 (see Figure 10 When there is no need for a bridge crossing, the first support member 12 rotates relative to the mounting base 11 onto the vehicle body 20, while the second support member 13 rotates to the folding position under the drive of the first drive member 17, thereby reducing the storage size requirement of the folding bridge crossing device 10. See also Figure 2When the transport vehicle 1 needs to transport goods, the first drive member 17 drives the first pivot 16 to move. During the movement of the first pivot 16, the first connecting member 14 rotates relative to the first carrier member 12, and simultaneously drives the second connecting member 15 to rotate relative to the second carrier member 13. Since the position of the first carrier member 12 remains stationary at this time, the first drive member 17 also moves synchronously relative to the first carrier member 12. Thus, through the second connecting member 15, a force is applied to the second carrier member 13 in a direction away from the first carrier member 12, causing the second carrier member 13 to rotate relative to the first carrier member 12. In this way, through the action of the first drive member 17, the second carrier member 13 can be driven to rotate to a working position parallel to the first carrier member 12 (see...). Figure 3 This significantly extends the overall length of the folding bridge device 10, thereby reducing the angle between the folding bridge device 10 and the ground 30 and improving the transportability of goods. Simultaneously, when the second load-bearing member 13 is in the working position, the first connecting member 14 supports the first load-bearing member 12, and the second connecting member 15 supports the second load-bearing member 13, allowing the folding bridge device 10 to more stably carry goods, thus further improving the operational safety of the folding bridge device 10.
[0034] In addition, see Figure 4 and Figure 5 The first driving member 17 drives the first pivot 16 to move, thereby driving the first connecting member 14 and the second connecting member 15 to move. This can amplify the rotation angle of the second carrier member 13 relative to the first carrier member 12, so as to prevent the second carrier member 13 from entering the dead point after rotating to the working position. This ensures that the first driving member 17 can smoothly drive the second carrier member 13 to rotate from the working position to the folding position.
[0035] It is understandable that the goods transported by the folding bridge device 10 may be transport components such as tracked vehicles, which carry products.
[0036] In one embodiment, the first drive member 17 may be configured as a hydraulic cylinder. The fixed end of the hydraulic cylinder is rotatably connected to the first support member 12. The output end of the hydraulic cylinder is rotatably connected to the first pivot 16.
[0037] In one embodiment, see Figure 2 The first support member 12 has a first extension 121 that extends obliquely toward the second support member 13, and the first connector 14 is rotatably connected to the first extension 121. The second support member 13 has a second extension 131 that extends obliquely toward the first support member 12, and the second connector 15 is rotatably connected to the second extension 131.
[0038] Thus, the first extension 121 and the second extension 131 are arranged such that the first pivot 16 is spaced apart from the first support member 12 and the second support member 13, providing rotation space for the first connector 14 and the second connector 15, so as to ensure that the first drive member 17 can drive the first pivot 16 to move, drive the second connector 15 to rotate, and then drive the second support member 13 to rotate relative to the first support member 12.
[0039] In one embodiment, see Figure 2 The second connector 15 has a receiving hole 151. When the second support member 13 is in the folded position, the end of the first connector 14 near the second connector 15 is received in the receiving hole 151. This avoids interference during relative rotation between the first connector 14 and the second connector 15. In other embodiments, the receiving hole 151 may also be formed in the first connector 14. This application does not specifically limit the location of the receiving hole 151.
[0040] In one embodiment, see Figure 6 The first support member 12 includes two first longitudinal beams 122, multiple first transverse beams 123, and multiple first support plates 124. The two first longitudinal beams 122 are spaced apart along the length of the first transverse beams 123. The multiple first transverse beams 123 are spaced apart between the two first longitudinal beams 122 along the length of the first longitudinal beams 122. The two ends of the multiple first transverse beams 123 are respectively connected to the two first longitudinal beams 122. A first support plate 124 is provided between two adjacent first transverse beams 123. A first connecting member 14 rotatably connects to the middle portion of one of the first transverse beams 123. A first extension 121 connects to one of the multiple first transverse beams 123 closest to the second support member 13.
[0041] Thus, the multiple first crossbeams 123 and the two second longitudinal beams 132 can improve the structural stability of the first load-bearing member 12, ensuring that the first load-bearing member 12 can stably bear heavy goods. The multiple first load-bearing plates 124 can provide a smooth transport surface, ensuring the transport reliability of transport components such as tracked vehicles.
[0042] Specifically, multiple first bearing plates 124 and multiple first crossbeams 123 together form the first bearing surface 125.
[0043] In other embodiments, the first support plate 124 may also be constructed as a single plate and directly fixed to the plurality of first crossbeams 123. The first support plate 124 forms a first support surface 125 on its own.
[0044] Specifically, one end of the first driving member 17 is rotatably connected to the middle of one of the first crossbeams 123. This improves the driving stability of the first driving member 17 in driving the second load-bearing member 13 to rotate.
[0045] In one embodiment, see Figure 6 The first bearing plate 124 includes a bearing section 1241 and two connecting sections 1242. The two connecting sections 1242 are bent and connected to the two ends of the bearing section 1241 along the length direction of the first crossbeam 123. The two connecting sections 1242 are respectively connected to the two first longitudinal beams 122. The two connecting sections 1242 can be connected to the first longitudinal beams 122 by various connection methods such as welding and fastening components.
[0046] In one embodiment, see Figure 7 The second support member 13 includes two second longitudinal beams 132, multiple second transverse beams 133, and multiple second support plates 134. The two second longitudinal beams 132 are spaced apart along the length of the second transverse beams 133. The multiple second transverse beams 133 are spaced apart between the two second longitudinal beams 132 along the length of the second longitudinal beams 132. The two ends of the multiple second transverse beams 133 are respectively connected to the two second longitudinal beams 132. The second support plates 134 are disposed on the multiple second transverse beams 133. A second connecting member 15 rotatably connects to the middle portion of one of the second transverse beams 133. The second extension portion 131 connects to one of the multiple second transverse beams 133 closest to the first support member 12.
[0047] Thus, the multiple first crossbeams 123 and the two second longitudinal beams 132 can improve the structural stability of the first load-bearing member 12, ensuring that the first load-bearing member 12 can stably bear heavy goods. The multiple first load-bearing plates 124 can provide a smooth transport surface, ensuring the transport reliability of transport components such as tracked vehicles.
[0048] Specifically, the surface of the second bearing plate 134 facing away from the surfaces of the multiple second crossbeams 133 forms the first bearing surface 125.
[0049] In other embodiments, the number of second bearing plates 134 can be multiple, and one second bearing plate 134 is disposed between two adjacent second crossbeams 133. The multiple second bearing plates 134 and the multiple second crossbeams 133 together form the second bearing surface 135.
[0050] Specifically, multiple second bearing plates 134 and multiple second crossbeams 133 together form the first bearing surface 125.
[0051] In one embodiment, see Figure 2The first support member 12 has a first support surface 125, and the second support member 13 has a second support surface 135. A first connecting portion 126 is formed at the end of the first support member 12 away from the first support surface 125, and a second connecting portion 136 is formed at the end of the second support member 13 away from the second support surface 135. The second connecting portion 136 extends toward the first support member 12, and the portion of the second connecting portion 136 extending out of the second support member 13 is rotatably connected to the first connecting portion 126 so that when the second support member 13 rotates to the point where the second support surface 135 is coplanar with the first support surface 125, it abuts against the first support member 12.
[0052] Thus, by cooperating with the first connecting part 126 and the second connecting part 136, it can be ensured that when the second carrier 13 enters the working position, the gap between the first carrier 12 and the second carrier 13 is minimal, so as to avoid the impact of excessive gap on the transportation of goods, thereby further improving the safety of goods transportation. In addition, the positioning of the first connecting part 126 and the second connecting part 136 can prevent them from interfering with the transportation of goods, so as to ensure the smooth transportation of goods.
[0053] Optionally, there are two first connecting parts 126. The two first connecting parts 126 are respectively connected to the first longitudinal beam 122. There are also two second connecting parts 136. The two second connecting parts 136 are respectively connected to the second longitudinal beam 132.
[0054] In one embodiment, see Figure 2 The first support member 12 has a top abutment 128, which abuts against the second support member 13 when the second support member 13 is in the folded position. Thus, the top abutment 128 limits the movement of the second support member 13, preventing it from continuously rotating towards the first support member 12 and potentially damaging it, thereby improving the service life of the folding bridge device 10. Each of the two first longitudinal beams 122 may be provided with a top abutment 128.
[0055] In one embodiment, see Figure 2 A retaining ring 137 is formed on the side of the second support member 13. The retaining ring 137 is used to connect to the vehicle body 20 via a connecting structure such as a buckle or rope, so as to fix the second support member 13 to the vehicle body 20 and improve the installation reliability of the folding bridge device 10 on the vehicle body 20. The retaining ring 137 can be provided on the second longitudinal beam 132.
[0056] Specifically, the retaining ring 137 is positioned directly opposite one of the top abutments 128.
[0057] In this embodiment, see Figure 8 and Figure 9The folding bridge device 10 also includes a base 181 and a second drive member 182. The base 181 is used to connect to the vehicle body 20. The second drive member 182 is rotatably connected to the base 181, and the other end of the second drive member 182 is rotatably connected to the first support member 12. The second drive member 182 is used to drive the second support member 13 to rotate relative to the mounting base 11. In this way, by driving the first support member 12 to move through the second drive member 182, the first support member 12 can be rotated relative to the mounting base 11, so that the first support member 12 can be rotated to be stored in the vehicle body 20, or extend to the ground 30 outside the vehicle body 20, thereby improving the ease of use of the folding bridge device 10.
[0058] In one embodiment, the second drive member 182 may be configured as a hydraulic cylinder. The fixed end of the hydraulic cylinder is rotatably connected to the first support member 12. The output end of the hydraulic cylinder is rotatably connected to the mating part 127.
[0059] Optionally, the base 181 is disposed between the two first longitudinal beams 122. This can improve the driving stability of the second driving member 182 driving the first load-bearing member 12 to rotate.
[0060] In one embodiment, see Figure 8 and Figure 9 The first support member 12 has a mating part 127 formed at one end near the mounting base 11. The mating part 127 has a mating groove 1271 on the side near the second drive member 182. The mounting base 11 includes a second pivot 111, which is fitted into the mating groove 1271. The second drive member 182 is connected to the mating part 127 and is configured to drive the mating part 127 to rotate around the second pivot 111.
[0061] Thus, the structure of the second pivot 111 and the mating part 127 is simple to process, the mating is reliable, it is easy to install, and the redundancy is high, which can ensure the reliability of the rotation of the mating part 127 relative to the second pivot 111.
[0062] In other embodiments, the mating part 127 may also have a through mating hole, and the second pivot 111 may be inserted into the mating hole, which can also enable the mating part 127 to rotate relative to the second pivot 111.
[0063] In one embodiment, see Figure 8 and Figure 9 The mounting base 11 also includes a base body 112, which is disposed between two first longitudinal beams 122. A second pivot 111 rotatably passes through the base body 112, and the two ends of the second pivot 111 are rotatably connected to the two first longitudinal beams 122, respectively. In this way, the rotational stability between the first bearing member 12 and the mounting base 11 can be further improved.
[0064] Specifically, there are two seats 112. The two seats 112 are spaced apart between the two first longitudinal beams 122 along the length of the first longitudinal beam 122.
[0065] In one embodiment, the mating part 127 is connected to the first crossbeam 123 at the farthest end of the first support member 12 away from the second support member 13, and is inclined in the direction away from the second support member 13 and the second drive member 182.
[0066] See Figure 10 and Figure 11 This embodiment also provides a transport vehicle 1, including a vehicle body 20 and a folding bridge device 10 as described in any of the preceding embodiments. The mounting base 11 of the folding bridge device 10 is fixedly connected to the vehicle body 20. The base 181 of the folding bridge device 10 is also fixedly connected to the vehicle body 20. The vehicle body 20 may be provided with an accommodating space 21 to accommodate transport components such as tracked vehicles, or to accommodate goods. The folding bridge device 10 may be disposed at the opening of the accommodating space 21.
[0067] The transport vehicle 1 in this embodiment has the folding bridge device 10 of any of the aforementioned embodiments, and therefore has the beneficial effects of the bridge device of any of the aforementioned embodiments, which will not be repeated here.
[0068] In one embodiment, the mounting base 11 is connected to the rear end of the vehicle body 20 and extends rearward along the length of the vehicle body 20. The first support member 12 is rotatably connected to the end of the mounting base 11 opposite to the vehicle body 20.
[0069] In one embodiment, see Figure 11 The second support member 13 has an inclined surface 138 at the end opposite to the first support member 12. When the second support member 13 is in the working position and the second drive member 182 drives the first support member 12 to move to a position extending toward the ground 30, the inclined surface 138 is in contact with the ground 30. In this way, the contact area between the second support member 13 and the ground 30 can be increased, thereby improving the stability of the folding bridge device 10 erected on the ground 30.
[0070] In one embodiment, see Figure 11 The folding bridge device 10 also includes a support column 183. The support column 183 is connected to either the second support member 13 or the first support member 12. When the second support member 13 is in the working position and the second drive member 182 drives the first support member 12 to move towards the ground 30, the support column 183 abuts against the ground 30. The support column 183 provides further support to the folding bridge device 10, improving the overall structural stability of the folding bridge device 10.
[0071] In one embodiment, there are two folding bridge devices 10. The two folding bridge devices 10 are spaced apart along the width direction of the vehicle body 20. In this way, it is convenient for transport components such as tracked vehicles to pass through the two folding bridge devices 10 and move into the vehicle body 20.
[0072] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Any other corresponding changes and modifications made based on the technical concept of this application should be included within the scope of protection of the claims of this application.
