Description
Technical Field
The invention belongs to the technical field of vehicles, and particularly relates to a draw-out type boarding platform combined with a side protective guard for a vehicle.
Background
The above-mentioned vehicles mainly refer to special vehicles such as rescue vehicles for armed police, police and fire fighting vehicles for fire department, etc. Small generators for rescue purposes, air compressors, lighting, motor-driven hydraulic pumps, break-in devices (such as jacks, hydraulic shears), climbing devices, medical emergency devices, fire-fighting devices, food and even personal protective equipment, etc., are often fitted on such vehicles. Since the chassis of such a vehicle is large from the ground, usually up to about one meter, it is laborious for a rescuer to stand on the ground to take or store equipment in the equipment compartment after opening the compartment doors corresponding to the two sides of the equipment compartment.
Providing a step on a vehicle of the aforementioned type facilitates the taking and placing of equipment by rescuers to some extent, and technical information on the step can be found in published chinese patent documents such as CN200973933Y (step structure of fire engine), CN101214801A (linked step structure), CB101480936B (movable step structure of fire engine), CN101480935B (movable step structure of fire engine), CN102935827B (rotary step structure of fire engine), CN105480155A (rotary step structure linked to a passenger room door of fire engine), CN101487374B (foldable boarding ladder), and CN203808816U (telescopic boarding ladder), and so on.
One of the disadvantages of the pedal structure disclosed in the above patent is that, because it is installed at a specific position, it cannot extend to one side or two side areas of the length direction of the equipment compartment, and there is a great inconvenience factor for taking and placing the equipment, for example, when taking and placing the corresponding equipment to the equipment compartment in an area far away from the pedal, it is often impossible to ascend with the aid of the pedal; secondly, because there is no structural relevance between the foot rest and the side guard rail of the vehicle, and the foot rest is usually installed at a position avoiding the side guard rail, on one hand, the installation position of the foot rest is critical, on the other hand, the function is monotonous, and on the other hand, the resource saving is not facilitated.
As is known in the art, in consideration of road conditions, particularly pedestrians and the safety of vehicles, the bottom of the guard rail of the special vehicle in the length direction is relatively close to the ground, i.e., the distance between the guard rail and the ground is relatively small, but the guard rail cannot provide force for a rescuer to take and place the equipment in the equipment compartment, i.e., the guard rail does not have the function of ascending the height of the rescuer. Therefore, if reasonable improvement is made to make the side guard rail have both protection and ascending functions, it is an extremely good choice.
The publication No. CN201784562U recommends a "roll over guard rail for special vehicles", which solves the problem of lifting and lowering of the side guard rail, and when lowered, can prevent foreign objects from entering the bottom of the vehicle to ensure safety, and when raised, can satisfy the adaptability to road undulations (see paragraphs 0006 and 0012 to 0013 of the specification of the patent in particular). The granted publication No. CN2017845460U provides a "sliding guard rail for special vehicles", which has the effect of heteroworking with the aforementioned CN201784562U, and specifically, see paragraphs 0006 and 0013 to 0014 of the specification of the patent. However, these two patents do not teach that the side guard rail has the function of a foot board to help a rescuer to get and put the equipment to the equipment compartment when ascending, and even when the applicant refers to the above-mentioned technical contents of the foot board patent, the patent does not teach a specific structure that the side guard rail has the function of a foot board.
In view of the above prior art, the applicant has made a long-lasting and beneficial iterative design, which eventually results in the technical solution described below, and has proved to be feasible by computer simulation and deduction tests under the security measures taken.

Referring to fig. 4 in conjunction with fig. 1, when the vehicle arrives at the rescue site and the rescue equipment is taken into the equipment compartment 30 in a state where the equipment compartment door 301 is opened, the rescue worker unlocks the left pillar 41 by the left pillar lock bolt 82 of the left pillar lock mechanism 8, that is, the left pillar lock bolt 82 exits the left pillar lock hole 411, and the right pillar lock mechanism 10 operates in the same manner, that is, the right pillar lock bolt of the right pillar lock mechanism 10 exits the right pillar lock hole on the right pillar 51. The upper guard rail 6 is then pulled out together with the lower guard rail 7 under the guidance of the left and right guide rails 4, 5 of the boarding platform. Next, the lower guard rail left locking mechanism 9 is unlocked to the left end of the lower guard rail 7, that is, the lower guard rail left locking bolt 92 is made to exit from the lower guard rail left locking hole 77, and the operation of the lower guard rail right locking mechanism 20 is the same as that of the lower guard rail right locking mechanism 20, that is, the lower guard rail right locking bolt of the structural system of the lower guard rail right locking mechanism 20 is made to exit from the lower guard rail right locking hole 78, so that the upper and lower guard rails 6 and 7 are stepped as shown in fig. 4. The rescue personnel can ascend along the steps to take or place various rescue equipment to the equipment compartment.
In conclusion, the technical scheme provided by the invention overcomes the defects in the prior art, successfully completes the invention task and faithfully realizes the technical effects listed in the technical effect column by the applicant.
