Description

Technical Field

[0001] This application relates to the field of fire-fighting equipment carrier technology, and in particular to a vehicle for transporting assault boats. Background Technology

[0002] In previous technologies, when loading inflatable boats, a winch would drive a steel cable 300, which would pull the inflatable boat towing hook 201 at the front of the boat, thus lifting the inflatable boat 200 onto the transport vehicle. For example... Figure 1 As shown, because the towing hook 201 at the front of the assault boat protrudes, it often gets stuck on the wire rope guide wheel 4 during loading, causing difficulties in loading and unloading. Usually, the front of the transport vehicle must be raised and the rear lowered to complete the loading. During the process of pulling the assault boat forward, the front of the vehicle may slam into the ground, potentially damaging the front wheels of the transport vehicle. This loading process is extremely cumbersome and dangerous. Therefore, there is an urgent need to develop an assault boat transport vehicle that can solve the aforementioned problems. Summary of the Invention

[0003] The purpose of this application is to provide a transport vehicle for assault boats, which solves the problems of existing assault boat transport vehicles being prone to getting stuck on the towing hook, difficult loading and unloading, and easy damage to the front wheels of the transport vehicle.

[0004] To solve the above-mentioned technical problems, this application provides an assault boat transfer vehicle, including a frame, a support part and a guide part; the frame includes a rear crossbeam, a first crossbeam and a second crossbeam, the first crossbeam is disposed at the front of the rear crossbeam, the second crossbeam is disposed at the front of the first crossbeam, the rear crossbeam is cut with a notch in the middle, and a wire rope guide wheel is disposed at the upper middle part of the first crossbeam.

[0005] The support has a used state and a retracted state. When the support is in the used state, it is used to support the rear of the vehicle frame between the vehicle frame and the ground. When the support is in the retracted state, it can be retracted from the rear of the vehicle frame between the vehicle frame and the ground. The guide is provided at the rear of the vehicle frame and is used to guide the assault boat onto the vehicle.

[0006] Optionally, the support includes a leg frame having a first end and a second end disposed opposite to each other, the first end of the leg frame being hinged to the first crossbeam;

[0007] When the support is in the use state, the second end of the outrigger is supported on the ground; when the support is in the retracted state, the second end of the outrigger is located at the notch of the rear crossbeam.

[0008] Optionally, both sides of the second end of the outrigger are connected to limit blocks. When the outrigger is flipped up to the horizontal position, the limit blocks are blocked by the rear crossbeam. The limit blocks are provided with locking holes, and the rear crossbeam is provided with locking brackets. Locking pins are threaded onto the locking brackets. When the support is in the retracted state, the locking holes correspond to the locking pins, and the locking pins can pass through the locking holes.

[0009] Optionally, both sides of the second end of the outrigger are connected to a stop bar, and the free end of the stop bar is connected to a flexible blocking member. When the support is in the retracted state, the flexible blocking member abuts against the rear of the assault boat.

[0010] Optionally, the flexible blocking element is a rubber wheel.

[0011] Optionally, the guide section includes two guide frames respectively connected to both sides of the rear crossbeam. The guide frames extend from the rear crossbeam to the lower rear. The lower inner side of the guide frame is rotatably connected to a first guide wheel via a first rotating shaft. The extension direction of the first rotating shaft is perpendicular to the movement direction of the assault boat on the vehicle frame.

[0012] Optionally, the guide frame is arc-shaped.

[0013] Optionally, the guide portion further includes two mounting seats respectively disposed on both sides of the rear crossbeam. The mounting seats are connected to the upper rear of the rear crossbeam, and a second guide wheel is rotatably connected to the inner side of the mounting seat via a second rotating shaft.

[0014] Optionally, each of the first guide wheel and the second guide wheel is a spherical guide wheel.

[0015] Optionally, the rear crossbeam is further provided with stops on both sides, and the upper end of the guide frame is provided with a downward-facing slot. The guide frame is engaged with the rear crossbeam between the stops and the mounting base through the slot.

[0016] In this embodiment, the inflatable boat transport vehicle breaks the rear crossbeam at the rear of the frame and moves the wire rope guide wheel, originally located in the middle of the rear crossbeam, onto the first crossbeam, which serves as a secondary rear crossbeam. When the inflatable boat transport vehicle approaches the rear of the vehicle, the inflatable boat towing hook passes through the gap without being jammed by the wire rope guide wheel. When the head of the inflatable boat moves to the rear of the vehicle, the height of the towing hook is higher than the wire rope guide wheel on the first crossbeam because the front arc surface of the inflatable boat is raised, and the towing hook will no longer be jammed by the wire rope guide wheel. Furthermore, this embodiment eliminates the need to lift the front of the transport vehicle when loading inflatable boats, simplifying the loading and unloading process. In addition, this embodiment also includes outriggers to support the rear of the frame, preventing the vehicle from tilting its nose when the head of the inflatable boat is pulled to the rear, thus avoiding damage to the front wheels when the nose falls. Meanwhile, because the outriggers have both a working and a retracted state, they not only ensure a smooth and stable loading process for the assault boat transport vehicle, but also do not affect the vehicle's movement. Furthermore, the assault boat transport vehicle in this embodiment has a guide section at the rear of the frame. This guide section guides the assault boat onto the vehicle, preventing it from getting stuck at the rear of the frame and making the loading process smoother. Therefore, the assault boat transport vehicle in this embodiment has advantages such as preventing the assault boat's towing hook from being jammed by the wire rope guide wheel during loading and unloading, simplifying loading and unloading, preventing damage to the front wheels from tilting, and ensuring smooth loading of the assault boat.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0034] The core of this application is to provide a vehicle for transporting assault boats.

[0035] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] like Figure 2-6As shown, this application provides a vehicle 100 for transporting assault boats, including a frame 1, a support 2, and a guide 3. The frame 1 includes a rear crossbeam 11, a first crossbeam 12, and a second crossbeam 13. The first crossbeam 12 is located in front of the rear crossbeam 11, and the second crossbeam 13 is located in front of the first crossbeam 12. The rear crossbeam 11 has a notch 111 cut in the middle, and a wire rope guide wheel 4 is provided in the upper middle part of the first crossbeam 12. It is understood that the frame 1 includes multiple crossbeams, not limited to the crossbeams mentioned in this embodiment.

[0037] Support 2 has a usage state (e.g.) Figure 3 (as shown) and collapsed state (as shown) Figure 2 and Figure 6 As shown, when the support part 2 is in use, it supports the rear of the frame 1 between the frame 1 and the ground. When the support part 2 is in the retracted state, it can be retracted from the rear of the frame 1 between the frame 1 and the ground. The guide part 3 is located at the rear of the frame 1 and is used to guide the assault boat 200 onto the vehicle. Preferably, the lowest point of the guide part 3 is not lower than the height of the rear axle of the assault boat transfer vehicle 100 to avoid affecting the movement of the assault boat transfer vehicle 100.

[0038] In this embodiment, the assault boat transport vehicle 100 breaks the rear crossbeam 11 at the rear of the frame 1 and moves the wire rope guide wheel 4, originally located in the middle of the rear crossbeam 11, onto the first crossbeam 12, which serves as a secondary rear crossbeam. When the assault boat 5 approaches the rear of the assault boat transport vehicle 100, the upper front part of the assault boat 200 first contacts the rear crossbeam 11. Because the rear crossbeam 11 at the rear of the assault boat transport vehicle 100 is broken, the assault boat towing hook 201 passes through the gap and is not caught by the wire rope guide wheel 4. When the head of the assault boat 200 moves to the rear of the assault boat transport vehicle 100, because the front arc surface of the assault boat 200 is raised, the height of the assault boat towing hook 201 is higher than the wire rope guide wheel 4 located on the first crossbeam 12, and the assault boat towing hook 201 is no longer caught by the wire rope guide wheel 4. Meanwhile, in this embodiment, when loading the assault boat 201, the front of the assault boat transport vehicle 100 does not need to be raised, making the loading and unloading process simple.

[0039] Furthermore, the inflatable boat transport vehicle 100 in this embodiment is also equipped with a support part 2 to support the rear of the vehicle frame. This prevents the inflatable boat transport vehicle 100 from tilting its nose when the front of the inflatable boat 200 is first pulled to the rear of the vehicle, thus avoiding damage to the front wheels when the front of the vehicle falls. At the same time, since the support part 2 has both a used state and a retracted state, it not only ensures a smooth and stable loading process for the inflatable boat 200 onto the transport vehicle 100, but also does not affect the movement of the transport vehicle 100.

[0040] In addition, the inflatable boat transfer vehicle 100 in this embodiment is provided with a guide part 3 at the rear of the vehicle frame. The guide part 3 guides the inflatable boat 200 onto the vehicle, which can prevent the inflatable boat 200 from getting stuck at the rear of the vehicle frame 1 and make the process of loading the inflatable boat 200 onto the vehicle smoother.

[0041] Therefore, the assault boat transfer vehicle 100 in this embodiment has the advantages of preventing the assault boat towing hook 201 from being stuck by the wire rope guide wheel 4 when loading and unloading the assault boat 200, simplifying loading and unloading, avoiding damage to the front wheel by tilting the boat, and ensuring smooth loading of the assault boat 200.

[0042] Based on the above embodiments, further, as Figure 2 , Figure 3 and Figure 6 As shown, the support unit 2 includes a leg frame 21 and a push rod 22. The leg frame 21 has a first end and a second end arranged opposite to each other. The first end of the leg frame 21 is hinged to a first crossbeam 12. One end of the push rod 22 is hinged to a second crossbeam 13, and the other end is hinged to the side of the leg frame 21. When loading and unloading the assault boat 200, the support unit 2 is in use (e.g., Figure 3 As shown), the push rod 22 shortens, causing the second end of the outrigger 21 to be supported on the ground; when the assault boat transfer vehicle 100 moves, the support part 2 is in the retracted state (as shown). Figure 2 and Figure 6 As shown, the push rod 22 extends so that the second end of the outrigger 21 is located at the notch 111 of the rear crossbeam 11. The push rod 22 can be an electric push rod or a hydraulic push rod, and its extension and retraction can be controlled remotely. By automatically controlling the extension and retraction of the push rod, the support part 2 can be automatically controlled to be in the use state or the retracted state, which makes the assault boat transfer vehicle 100 of this embodiment more convenient to use.

[0043] Specifically, the first end of the outrigger 21 is connected to a first bracket 23, and the first bracket 23 is hinged to a second bracket 25 connected to the rear end of the first crossbeam 12 via a first pin 24. One end of the push rod 22 is hinged to a third bracket 27 connected to the lower end of the second crossbeam 13 via a second pin 26, and the other end of the push rod 22 is hinged to a fourth bracket 29 connected to the side of the outrigger 21 via a third pin 28. This makes the structural arrangement of the assault boat transfer vehicle 100 in this embodiment simpler and more reasonable.

[0044] It should be noted that in this embodiment, the support part 2 can also be simply controlled manually (not shown in the figure) to support the second end of the outrigger 21 on the ground or at the notch 111 of the rear crossbeam 11.

[0045] Based on the above embodiments, further, as Figure 2 and Figure 6As shown, limit blocks 5 are connected to both sides of the second end of the outrigger 21, i.e., the left and right sides of the frame. When the outrigger 21 is flipped up to the horizontal position, these limit blocks are blocked by the rear crossbeam 11, preventing the outrigger 21 from continuing to flip up. The limit blocks 5 are provided with locking holes 51. The rear crossbeam 11 is provided with a locking bracket 112, and a locking pin 7 is threaded onto the locking bracket 112. When the support part 2 is in the retracted state, i.e., when the outrigger 21 is flipped up to the horizontal limit position, the locking hole 51 corresponds to the locking pin 7, and the locking pin 7 can pass through the locking hole 51 to fix the outrigger 21 to the frame 1. Preferably, the locking pin is a commercially available self-locking locking pin. After the locking pin 7 passes through the locking hole 51, it needs external force to be pulled out, which can increase the reliability and safety of the connection. Additionally, a locking pin 7 is installed to lock the outrigger 21 onto the rear crossbeam 11, which allows the outrigger 21 to be supported without relying on the push rod 22, thus avoiding damage to the push rod 22.

[0046] Based on the above embodiments, further, as Figure 2 , Figure 3 and Figure 6 As shown, both sides of the second end of the outrigger 21 are connected to stop bars 6, and the free end of the stop bar 6 is connected to a flexible blocking member 61. When the support part 2 is in the retracted state, the flexible blocking member 61 abuts against the rear of the assault boat 200. The flexible blocking member 61 can prevent damage to the surface of the assault boat 200. In addition, the use of the flexible blocking member 61 to block the assault boat 200 can prevent the assault boat 200 from falling off the assault boat transport vehicle 100 during the movement of the assault boat transport vehicle 100.

[0047] Preferably, the stop bar 6 is arranged perpendicularly to the outrigger frame 21. This not only facilitates the support of the flexible stop 61 for the assault boat 200, but also allows the stop bar 6 to be supported on the ground when the support part 2 is in use. The stop bar 6 and the outrigger frame 21 work together to provide more stable support for the rear of the assault boat transfer vehicle 100.

[0048] Based on the above embodiments, further, as Figure 2 As shown, the flexible blocking component 61 is a rubber wheel. The rubber wheel can rotate with the up-and-down swaying of the assault boat 200, which can reduce the friction between the rubber wheel and the assault boat 200, thereby further preventing damage to the surface of the assault boat 200.

[0049] Based on the above embodiments, further, as Figure 3 , Figure 4 and Figure 6As shown, the guide section 3 includes two guide frames 31 respectively connected to both sides of the rear crossbeam 11. The guide frames 31 extend from the rear crossbeam 11 to the lower rear. The lower inner side of the guide frame 31 is rotatably connected to a first guide wheel 33 via a first rotating shaft 32. The extension direction of the first rotating shaft 32 is perpendicular to the movement direction of the assault boat 200 on the frame 1. The movement direction of the assault boat 200 on the frame 1 is the forward and backward movement direction of the assault boat 200 during the process of being pulled onto or unloaded from the assault boat transfer vehicle 100. By setting the guide frames 31 extending from the rear crossbeam 11 to the lower rear and the first guide wheels 33 mounted on the guide frames 31, the assault boat 200 can be gradually guided to move to the upper part of the assault boat transfer vehicle 100, reducing the movement resistance of the assault boat 200.

[0050] Based on the above embodiments, further, as Figure 3 and Figure 6 As shown, the guide frame 31 is arc-shaped so as to match the arc surface at the front end of the assault boat 200, thereby further reducing the moving resistance of the assault boat 200.

[0051] Based on the above embodiments, the guide part 3 further includes two mounting seats 34 respectively disposed on both sides of the rear crossbeam 11. The mounting seats 34 are connected to the rear upper part of the rear crossbeam 11, and the inner side of the mounting seat 34 is rotatably connected to the second guide wheel 36 through the second rotating shaft 35.

[0052] Based on the above embodiments, further, as Figure 3 and Figure 6 As shown, each of the first guide wheel 33 and the second guide wheel 36 is a spherical guide wheel. Making the first guide wheel 33 and the second guide wheel 36 that come into contact with the surface of the assault boat 200 spherical can further reduce the friction between the assault boat 200 and the first guide wheel 33 and the second guide wheel 36, thereby further avoiding damage to the surface of the assault boat 200.

[0053] Based on the above embodiments, further, as Figure 3 , Figure 4 and Figure 6 As shown, the rear crossbeam 11 is further provided with stops 113 on both sides, and the upper end of the guide frame 31 is provided with a downward-facing slot 311. The groove shape of the slot 31 matches the shape of the rear crossbeam 11, and the guide frame 31 is engaged with the rear crossbeam 11 between the stops 113 and the mounting base 34 through the slot 311. Specifically, the slot 31 is a U-shaped slot. This can limit the position of the guide frame 31 and prevent the guide frame 31 from moving left and right during the guiding process, thus affecting the guiding effect. Figure 3 As shown, preferably, the length of the first pivot 32 can be shorter than that of the second pivot 35, so that the first guide wheel 33 and the second guide wheel 36 are approximately in a straight line in the front-rear direction of the frame, thereby providing better guidance and support for the assault boat 200.

[0054] In addition, the guide frame 31 is snapped onto the rear crossbeam 11. When not in use, the guide frame 31 can be easily disassembled so that multiple assault boat transfer vehicles 100 can share it. This can also reduce the length of the assault boat transfer vehicle 100 and prevent the rear of the assault boat transfer vehicle 100 from being too close to the ground when it is moving.

[0055] The above provides a detailed description of the assault boat transport vehicle 100 provided in this application. The various embodiments in the specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.

[0056] It should also be noted that, in this specification, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
