In addition, for clarity and brevity, the description of known functions and structures has been omitted.

[0026] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0027] An embodiment of the present application provides a ramp device that can be used at a rescue vehicle drainage operation site to help a crawler-type water hose storage device get on and off a truck.

[0028] refer to Figure 1-Figure 5 The ramp device includes a first ramp plate 10, a second ramp plate 20, a first support frame 30, and a second support frame 40. The first ramp plate 10 has a first ramp surface 101 on its front side, and the second ramp plate 20 has a second ramp surface 102 on its front side. A movable connection is provided between the first ramp plate 10 and the second ramp plate 20, allowing them to fold together around the connection. When folded, the first and second ramp surfaces are located on the inner side of the fold. In one specific technical solution, the movable connection between the first ramp plate 10 and the second ramp plate 20 is specifically a hinge.

[0029] The first support frame 30 is provided on the back side of the first ramp plate 10, and includes a first support leg 31 and a first side support member 32. One end of the first support leg 31 is hinged to the end of the first ramp plate 10 close to the second ramp plate 20, so as to support the end of the first ramp plate 10 close to the second ramp plate 20 to make it higher than the other end; the first end of the first side support member 32 is hinged to the first support leg 31, and the second end of the first side support member 32 is slidably connected to the first ramp plate 10; and, as the second end of the first side support member 32 slides and adjusts on the first ramp plate 10, the first support leg 31 and the first side support member 32 can be rotated, folded on the back side of the first ramp plate 10, or unfolded.

[0030] The second support frame 40 is provided on the back side of the second ramp plate 20, and includes a second support leg 41 and a second side support member 42. One end of the second support leg 41 is hinged to the end of the second ramp plate 20 away from the first ramp plate 10, so as to support the end of the second ramp plate 20 away from the first ramp plate 10 to make it higher than the other end; the first end of the second side support member 42 is hinged to the second support leg 41, and the second end of the second side support member 42 is slidably connected to the second ramp plate 20; and, as the second end of the second side support member 42 slides and adjusts on the second ramp plate 20, the second support leg 41 and the second side support member 42 can be rotated, folded on the back side of the second ramp plate 20, or unfolded.

[0031] The ramp structure is composed of a first ramp plate 10 and a second ramp plate 20. Figure 1 In the illustrated structure, the first ramp plate 10 forms the lower half of the ramp, and the second ramp plate 20 forms the upper half. When the first ramp plate 10 and the second ramp plate 20 are unfolded to form the ramp, the first ramp surface 101 and the second ramp surface 102 are spliced ​​together to form a complete ramp surface, creating a passage for trucks to get on and off the crawler chassis. Furthermore, the first ramp plate 10 and the second ramp plate 20 are connected by a movable connection, allowing them to fold together around the connection. Therefore, when not in use, the first ramp plate 10 and the second ramp plate 20 can be folded and carried on the vehicle. At the work site, the first ramp plate 10 and the second ramp plate 20 can be unfolded to form the complete ramp structure.

[0032] refer to Figure 2 and Figure 3 The first support frame 30 is provided on the back side of the first ramp plate 10. As the second end of the first side support member 32 slides on the first ramp plate 10, the first leg 31 and the first side support member 32 can be switched between a folded state and an unfolded state. Figure 2 and Figure 3In the state shown, the first leg 31, in the deployed state, supports one end of the first ramp plate 10 near the second ramp plate 20, raising it higher than the other end to form an inclined ramp. Furthermore, the first side support member 32 is connected between the first ramp plate 10 and the first leg 31, forming a triangular structure. At this point, a position restriction can be applied to the second end of the first side support member 32, allowing the first side support member 32 to obliquely support the first leg 31, keeping it in the deployed state. Figure 5 In the illustrated state, the first leg 31 and the first side support 32 are folded onto the back side of the first ramp 10 in the folded state.

[0033] refer to Figure 2 and Figure 4 The second support frame 40 is provided on the back side of the second ramp plate 20. As the second end of the second side support member 42 slides on the second ramp plate 20, the second leg 41 and the second side support member 42 can be switched between the folded state and the unfolded state. Figure 2 and Figure 4 In the state shown, the second leg 41, in the deployed state, supports one end of the second ramp plate 20 away from the first ramp plate 10 so that it is higher than the other end, forming an inclined ramp. In addition, the second side support member 42 is connected between the second ramp plate 20 and the second leg 41, forming a triangular structure. At this time, a position restriction can be applied to the second end of the second side support member 42, allowing the second side support member 42 to obliquely support the second leg 41 and keep it in the deployed state. Figure 5 In the illustrated state, the second leg 41 and the second side support 42 are folded onto the back side of the second ramp plate 20 in the folded state.

[0034] Further references Figure 5 On the basis of folding the first support frame 30 on the back of the first ramp plate 10 and folding the second support frame 40 on the back of the second ramp plate 20, the front of the first ramp plate 10 and the front of the second ramp plate 20 are folded together. Figure 5 When folded, the first leg 31 is located within the length range of the first ramp plate 10 , and the second leg 41 is located within the length range of the second ramp plate 20 .

[0035] refer to Figure 3In one embodiment of the present application, a first ramp plate 10 is provided with a first slide groove 12. The first slide groove 12 is provided with a first limiting opening 121 on a side near the first leg 31. A first sliding body 321 is provided at the second end of the first side support member 32. The first sliding body 321 is slidably assembled in the first slide groove 12. When the first sliding body 321 slides into the first limiting opening 121, the first leg 31 and the first side support member 32 are in an extended state. Moreover, the first sliding body 321 can be stuck in the first limiting opening 121 to keep the first leg 31 and the first side support member 32 in the extended state. Furthermore, a fixed first limiting plate 11 is provided on the first ramp plate 10, and the first slide groove 12 is arranged on the first limiting plate 11. Specifically, the first sliding body 321 is installed in the first slide groove 12. When the first leg 31 rotates, the first sliding body 321 can slide in the first slide groove 12 to accommodate the rotation of the first leg 31. Furthermore, when the first leg 31 is rotated to a predetermined angle and in the unfolded state, the first sliding body 321 slides into the first limiting opening 121 and is caught by the first limiting opening 121, preventing it from sliding out freely, thus forming a self-locking state. When the first leg 31 needs to be folded, the first sliding body 321 can be manually removed from the first limiting opening 121.

[0036] refer to Figure 4 In one embodiment of the present application, the second ramp plate 20 is provided with a second chute 22. The second chute 22 has a second limiting opening 221 on a side near the second leg 41. A second sliding body 421 is provided at the second end of the second side support member 42. The second sliding body 421 is slidably assembled in the second chute 22. When the second sliding body 421 slides into the second limiting opening 221, the second leg 41 and the second side support member 42 are in an extended state. Furthermore, the second sliding body 421 can be locked in the second limiting opening 221 to maintain the second leg 41 and the second side support member 42 in the extended state. Furthermore, the second ramp plate 20 is provided with a fixed second limiting plate 21, and the second chute 22 is arranged on the second limiting plate 21. Specifically, the second sliding body 421 is installed in the second chute 22. When the second leg 41 rotates, the second sliding body 421 can slide in the second chute 22 to accommodate the rotation of the second leg 41. Furthermore, when the second leg 41 is rotated to a predetermined angle and in the unfolded state, the second sliding body 421 slides into the second limiting opening 221 and is caught by the second limiting opening 221, preventing it from sliding out freely, thus forming a self-locking state. When the second leg 41 needs to be folded, the second sliding body 421 can be manually removed from the second limiting opening 221.

[0037] refer to Figure 1In one embodiment of the present application, a first support frame 30 is disposed at corresponding positions on both sides of the first ramp plate 10, and the first legs 31 on both sides are connected together by a first transverse connector 51. Here, the first legs 31 on both sides are connected together to form an integral structure, which is more stable and reliable. A second support frame 40 is disposed at corresponding positions on both sides of the second ramp plate 20, and the second legs 41 on both sides are connected together by a second transverse connector 52. Here, the second legs 41 on both sides are connected together by the second transverse connector 52 to form an integral structure, which is more stable and reliable.

[0038] In one embodiment of the present application, the first and second ramp sections are provided with a textured structure. Furthermore, transverse ridges 13 are arranged at intervals along the length of the first and second ramp sections to form the textured structure. This textured structure reduces slippage when the hose storage device travels on the first and second ramp sections.

[0039] Therefore, in the above-mentioned technical solution, a movable connection is provided between the first ramp plate and the second ramp plate, and the two can be folded together around the connection portion. The first support frame is arranged on the back side of the first ramp plate, and includes a first support leg and a first side support member, and the first support leg and the first side support member can be rotated and folded on the back side of the first ramp plate or unfolded; the second support frame is arranged on the back side of the second ramp plate, and includes a second support leg and a second side support member, and the second support leg and the second side support member can be rotated and folded on the back side of the second ramp plate or unfolded. Therefore, the ramp device can be folded and stored, and the volume occupied after folding is small, and the operation is convenient, and no tools are required for unfolding and folding. In addition, the ramp device has no scattered accessories in both the unfolded and folded states, has a simple structural design, low process requirements, and is easy to process and manufacture.
