Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rescue vehicle parts, in particular to a folding ladder used for a rescue vehicle and a rescue vehicle. Background Art
[0002] When a road vehicle cannot drive normally due to a breakdown or an accident, a rescue vehicle is needed for rescue. Different rescue methods such as lifting, dragging, and traction are required for different faulty vehicle conditions. Therefore, the rescue vehicle needs to be equipped with corresponding rescue tools and accessories such as slings. When operators take and place tools or get on and off the vehicle, they need to use ladders and other passages to achieve this.
[0003] Currently, the ladders of existing rescue vehicles usually adopt fixed-step ladders, which are part of the covering parts. The fixed-step ladders serve as both side safety protection devices and ladders. They are mainly composed of steps, fixed brackets, etc. The ladders are fixedly connected to other covering parts or frames, which can provide convenience for the assemblers, users, inspection and maintenance personnel of the rescue vehicle to get on and off the vehicle and take tools.
[0004] Fixed step ladders can be divided into two types: straight ladder type and stair type. Straight ladder type fixed step ladders are arranged within the width of the vehicle body, while stair type fixed step ladders are usually arranged outside the width of the vehicle body. For straight ladders perpendicular to the ground, the step width is usually narrow, and handrails are generally required when using the ladder. The comfort is insufficient when getting on and off the vehicle, and it is inconvenient to use when taking and placing tools; for stair ladders with an angle to the ground, the shortcomings of vertical ladders can be overcome, and getting on and off the vehicle is more comfortable and it is more convenient to take tools, but it takes up a large space in the width and length directions of the vehicle, and it is difficult to arrange when the overall layout of the vehicle is compact and the space is limited. Utility Model Content
[0005] In view of the above-mentioned deficiencies in the prior art, the utility model provides a folding ladder for a rescue vehicle, comprising a fixed bracket, a rotating bracket and a gas spring, wherein the fixed bracket is used for fixedly connecting to a body of the rescue vehicle.
[0006] The rotating bracket is rotatably connected to the fixed bracket, for example, an axis is provided on the fixed bracket, and a hole is provided on the rotating bracket, so that the rotating bracket can rotate upward or downward around the rotating axis. The fixed bracket is provided with an upward limit surface and a downward limit surface, and the rotating bracket is provided with a corresponding upward matching surface and a downward matching surface, which are used to limit the upward and downward limit positions of the rotating bracket during the rotation process, so that the rotating bracket can only rotate between the preset upward limit position and the downward limit position.
[0007] The two ends of the gas spring are respectively hinged on the fixed bracket and the rotating bracket, which are used to provide buffering when the rotating bracket is moving downward and to overcome part of the gravity when the rotating bracket is moving upward, so that the rotation process of the rotating bracket is simpler and more reliable.
[0008] A pedal is provided on the rotating bracket, and when the rotating bracket rotates to the downward limit position, users can use the pedal to get on and off the vehicle.
[0009] When using the folding ladder, turn the rotating bracket downward to the downward limit position, and then use the pedal to get on and off the vehicle; after use, turn the rotating bracket upward to the upward limit position to fold it, thereby reducing the space occupied by the folding ladder.
[0010] Preferably, a limit block is provided on the fixed bracket, and the downward limit surface is provided on the limit block. When the rotating bracket rotates to the downward limit position, the downward matching surface abuts against the downward limit surface. The upward limit surface can be provided on the fixed bracket body. Of course, similarly, the upward limit surface can also be provided on the limit block. When the rotating bracket rotates to the upward limit position, the upward matching surface abuts against the upward limit surface.
[0011] Preferably, a latch is provided on the rotating bracket, and a latch hole matching the latch is provided on the fixed bracket corresponding to the upper limit position of the rotating bracket, which can further prevent the rotating bracket from opening accidentally. Similarly, a latch can also be provided on the fixed bracket, and a latch hole matching the latch is provided on the rotating bracket corresponding to the upper limit position of the rotating bracket.
[0012] Preferably, when the rotating bracket is at the lower limit position, the pedal is in a horizontal state, which is convenient for personnel to use. Further preferably, when the rotating bracket is at the upper limit position, the pedal is in a vertical state.
[0013] Preferably, the fixing bracket is provided with an armrest for easy use.
[0014] The utility model also provides a rescue vehicle, on which the folding ladder is installed.
[0015] Preferably, when the rotating bracket is in the upward limit position, the rotating bracket does not exceed the width of the rescue vehicle body, thereby reducing the space occupied when not in use.
[0016] The utility model can be turned over and unfolded to outside the width of the vehicle body when in use, which is convenient for getting on and off the vehicle and taking and placing tools. When not in use, it can be folded and stored to within the width of the vehicle body, which saves layout space and meets the width requirement of the vehicle in driving state.

[0023] like Figure 1 , Figure 2 As shown, the folding ladder comprises a fixed bracket 1, a rotating bracket 2 and a gas spring 3, wherein the fixed bracket 1 is used for fixedly connecting to a rescue vehicle body 4.
[0024] The rotating bracket 2 is rotatably connected to the fixed bracket 1, for example, an axis is provided on the fixed bracket 1, and a hole is provided on the rotating bracket 2, so that the rotating bracket 2 can rotate upward or downward around the rotating axis. The fixed bracket 1 is provided with an upward limit surface 11 and a downward limit surface 12, and the rotating bracket 2 is provided with a corresponding upward matching surface 21 and a downward matching surface 22, which are used to limit the upward and downward limit positions of the rotating bracket 2 during the rotation process, so that the rotating bracket 2 can only rotate between the preset upward limit position and the downward limit position.
[0025] The downward limit surface 12 of this embodiment is arranged on the limit block 13, and the limit block 13 is arranged on the fixed bracket 1. When the rotating bracket 2 rotates to the downward limit position, the downward matching surface 22 abuts against the downward limit surface 12. The upward limit surface 11 can be arranged on the fixed bracket 1 body. Of course, it can also be similar. The upward limit surface 11 is also arranged on the limit block 13. When the rotating bracket 2 rotates to the upward limit position, the upward matching surface 21 abuts against the upward limit surface 11. This embodiment takes the upward limit surface 11 arranged on the fixed bracket 1 body as an example.
[0026] The two ends of the gas spring 3 are respectively hinged on the fixed bracket 1 and the rotating bracket 2, which are used to provide buffering when the rotating bracket 2 is descending and to overcome part of the gravity when the rotating bracket 2 is ascending, so that the rotation process of the rotating bracket 2 is simpler and more reliable.
[0027] The rotating bracket 2 is provided with a pedal 23, and when the rotating bracket 2 rotates to the downward limit position, the user can use the pedal 23 to get on and off the vehicle. When the rotating bracket 2 is at the downward limit position, the pedal 23 is in a horizontal state, which is convenient for people to use. Further preferably, when the rotating bracket 2 is at the upward limit position, the pedal 23 is in a vertical state, which can reduce the space occupied on the outside. At the same time, a handrail 14 can be provided on the fixed bracket 1 to facilitate people to get on and off the vehicle.
[0028] When using the folding ladder, the rotating bracket 2 is rotated downward to the downward limit position, and then the pedal 23 is used to get on and off the vehicle; after use, the rotating bracket 2 is rotated upward to the upward limit position for folding, thereby reducing the space occupied by the folding ladder.
[0029] In this embodiment, a latch 5 is provided on the rotating bracket 2, and a latch hole 51 matching the latch 5 is provided on the fixed bracket 1 corresponding to the upper limit position of the rotating bracket 2, which can further prevent the rotating bracket 2 from accidentally opening.
