[0059] Please refer to Figure 3 The first boom 221 and the second boom 223 are respectively provided with two guide supports 210 along the Z-axis direction. Multiple guide parts 230 are provided on the outer wall of the guide support 210 at intervals. The outer wall of the guide support 210 is also provided with guide sliders 240.

[0060] Optionally, the guide section 230 includes a guide wheel.

[0061] Alternatively, please refer to Figure 3 Three guide wheels are spaced apart along the Z-axis on the outer wall of the guide bracket 210, and the guide slider 240 is positioned between two guide wheels. This arrangement of the guide part 230 and the guide slider 240 ensures the working stability between the mounting bracket 100 and the loading bracket 200, while also providing a simple structure and good guiding effect.

[0062] In this embodiment, please refer to Figure 1 The loading bracket 200 and the two guide brackets 210 are each fixed with a first reinforcing connecting plate 250.

[0063] The first reinforcing connecting plate 250 is a triangular plate; one side of one of the first reinforcing connecting plates 250 is connected to the first boom 221 and the first support 222, while the adjacent side is connected to the guide support 210; the other side of the first reinforcing connecting plate 250 is connected to the first boom 221 and the first support 222, while the adjacent side is connected to the guide support 210. This arrangement ensures the rigid connection and overall connection strength of the loading support 200.

[0064] In this embodiment, please refer to Figure 1 The loading bracket 200 is provided with two inclined second reinforcing connecting plates 260.

This arrangement ensures the rigid connection and overall connection strength of the loading bracket 200.

[0066] Please refer to Figure 1 A third reinforcing connecting plate 270 is also connected between the two guide brackets 210.

[0067] In this embodiment, the mounting bracket 100 and the loading bracket 200 are also limited to a certain position so that the mounting bracket 100 and the loading bracket 200 can be locked or disengaged.

[0068] In this embodiment, please refer to Figure 4 A limiting plate 150 is provided on the side of the mounting bracket 100 away from the loading part 220. A limiting structure 400 is provided inside the loading part 220. The limiting structure 400 and the limiting plate 150 can be limited and connected. The limiting structure 400 and the limiting plate 150 are limited and connected so that the loading bracket 200 is limited on the mounting bracket 100. Alternatively, the limiting structure 400 can be disengaged from the limiting plate 150 so that the loading bracket 200 is disengaged from the mounting bracket 100.

[0069] It is understandable that when loading fire-fighting equipment in the loading section 220, the limiting structure 400 is connected to the limiting plate 150 for limiting, and the loading bracket 200 is limited on the mounting bracket 100. The limiting structure 400 provides hard limiting for the loading bracket 200 and the mounting bracket 100 to prevent damage to the fire-fighting equipment caused by the failure of the driving component 300.

[0070] When it is necessary to remove the fire-fighting equipment from the vehicle, the limiting structure 400 is disengaged from the limiting plate 150, and the loading bracket 200 is disengaged from the mounting bracket 100. The loading bracket 200 can then be driven directly by the driving component 300 to remove the fire-fighting equipment from the vehicle, allowing the equipment to be taken off the vehicle for on-site use.

[0071] In this embodiment, the limiting plate 150 is provided with at least two limiting holes, and the limiting structure 400 includes at least two, with the limiting structure 400 corresponding to the limiting holes.

[0072] The two limiting structures 400 are respectively installed in the first boom 221 and the second boom 223.

[0073] In this embodiment, please refer to Figure 4The limiting structure 400 includes a handle 410, a locking shaft 420, a spring 430, and a limiting seat 450. The locking shaft 420 passes through the loading part 220, with its first end extending out of the loading part 220 and its second end connected to a limiting hole for limiting. The spring 430 is sleeved on the locking shaft 420 and located inside the loading part 220. One end of the spring 430 is connected to the locking shaft 420 for limiting, and the other end is connected to the inner wall of the loading part 220 for limiting. The first end of the locking shaft 420 is provided with a handle 410, and the loading part 220 is provided with a limiting seat 450 on the side near the handle 410. The limiting seat 450 is connected to the locking shaft 420 for limiting.

[0074] Understandably, firstly, the limiting of the loading bracket 200 and the mounting bracket 100 is released: rotate the handle 410 to release the locking shaft 420 from the limiting seat 450, the spring 430 resets and pushes the locking shaft 420 to move towards the handle 410, so that the locking shaft 420 is released from the limiting hole.

[0075] Second, limit the loading bracket 200 and the mounting bracket 100: push the handle 410 towards the limiting plate 150 so that the locking shaft 420 passes through the limiting hole so that the locking shaft 420 and the limiting hole are in a limited state; rotate the handle 410 so that the locking shaft 420 and the limiting seat 450 are limited.

[0076] Optionally, the loading part 220 is provided with a plurality of guide seats 460 along the setting direction of the locking shaft 420, and the guide seats 460 are provided with guide holes, through which the locking shaft 420 passes.

[0077] Optionally, the locking shaft 420 includes a first locking shaft 421 and a second locking shaft 422. One end of the first locking shaft 421 extends out of the loading part 220, and the other end is limitedly connected to one end of the second locking shaft 422. The other end of the second locking shaft 422 is limitedly connected to a limiting hole.

[0078] One end of the spring 430 is connected to the limiting surface of the second locking shaft 422, and the other end is connected to the inner wall of the loading part 220.

[0079] In this embodiment, the vehicle-mounted equipment lifting mechanism 010 includes a drive component 300.

[0080] In this embodiment, please refer to Figures 1-2 The drive unit 300 is set along the Z-axis direction. One end of the drive unit 300 is connected to the connecting bracket 130 of the mounting bracket 100, and the output shaft of the drive unit 300 is connected to the first bracket 222 of the loading bracket 200.

[0081] In this embodiment, the first bracket 222 of the loading bracket 200 is provided with two hinge plates spaced apart, and the output shaft of the drive member 300 is disposed between the two hinge plates and is hinged to the two hinge plates through a hinge member.

[0082] In this embodiment, the drive component 300 is a telescopic hydraulic cylinder. Telescopic hydraulic cylinders offer strong power, smooth operation, and high safety. Compared to other drive methods, using a telescopic hydraulic cylinder is more efficient and cost-effective. Of course, in other optional embodiments, the drive component 300 may include either a cylinder or a motor.

[0083] The working principle and process of the vehicle-mounted equipment lifting mechanism 010 and the fire truck provided in this embodiment of the utility model are as follows: When it is necessary to take the fire-fighting equipment off the vehicle for on-site use: rotate the handle 410 to release the locking shaft 420 from the limiting seat 450. The spring 430 resets and pushes the locking shaft 420 to move towards the handle 410, so that the locking shaft 420 is released from the limiting hole; thus, the limiting of the loading bracket 200 and the mounting bracket 100 is released. The driving component 300 drives the loading bracket 200 loaded with fire-fighting equipment to slide downward along the Z-axis relative to the mounting bracket 100 until the loading bracket 200 is lowered to a reasonable position, and the fire-fighting equipment can be taken out.

[0084] When placing the fire-fighting equipment on the loading bracket 200: push the fire-fighting equipment onto the loading section 220 of the loading bracket 200, and the driving component 300 drives the loading bracket 200 loaded with the fire-fighting equipment to slide upward relative to the mounting bracket 100 along the Z-axis until the loading bracket 200 returns to its original position. Further, push the handle 410 towards the limiting plate 150 so that the locking shaft 420 passes through the limiting hole, so that the locking shaft 420 and the limiting hole are in a limited position. Rotate the handle 410 to limit the locking shaft 420 against the limiting seat 450; thus, the loading bracket 200 and the mounting bracket 100 are limited.

[0085] In summary, the vehicle-mounted equipment lifting mechanism 010 and fire truck provided in this embodiment of the present invention have fire-fighting equipment mounted on the loading section 220 of the loading bracket 200. The loading bracket 200 is slidably connected to the guide groove of the mounting bracket 100 through the guide section 230. The driving component 300 drives the loading bracket 200, which is loaded with fire-fighting equipment, to slide up and down relative to the mounting bracket 100 along the Z-axis. By setting up the loading bracket 200, the mounting bracket 100, and the driving component 300, this application allows the fire-fighting equipment to be directly removed from the vehicle by driving the loading bracket 200 through the driving component 300 during actual use. This enables the fire-fighting equipment to be taken off the vehicle for on-site use. The vehicle-mounted equipment lifting mechanism 010 with this configuration solves the problem of difficult loading and unloading of fire-fighting equipment by operators, greatly reduces the labor intensity of loading and unloading personnel, saves a large amount of labor and time costs, and improves the work efficiency of firefighters.

[0086] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
