Description

A high-rise rescue vehicle

technical field

The utility model belongs to the technical field of vehicle engineering, in particular to a high-rise rescue vehicle.

Background technique

Among the current high-rise rescue equipment, the more mature rescue measures implemented by means of lifting and rotating, should be represented by the ladder. In practice, low efficiency has always plagued the rescue community, mainly in the small cloud bucket, which can neither transport multiple rescuers to the designated floor at one time nor transport multiple rescued people at one time.

This solution makes up for the above-mentioned defects of the ladder, especially can deliver the energetic rescue personnel to the expected floor in time, and carry out rescue and transportation, and the effect is significantly improved.

During the novelty search process, two similar patent projects were also retrieved.

Patent CN102166394.A "A high-altitude fire rescue device for high-rise buildings", after investigation, the shortcoming of this scheme is that it is constructed and fixed on the roof of a specific building, and it is impossible to install it on the roof of every building. , and the cost of daily maintenance after installation is too high, and it is not flexible.

The patent CN207418215.U "A High-altitude Rescue Vehicle" has the following defects:

First, the Road Safety Law has clear restrictions on the dimensions of the driving vehicle, that is, the total height of the vehicle body shall not exceed 4 meters, the maximum shall not exceed 4.2 meters, and the total width shall not exceed 2.5 meters. The "ladder frame group" in this design scheme is affected by the space occupied by the head box and the external lift box, so the cross-sectional size of the "ladder frame group" has to be compressed, which is easy to cause the overall rigidity of the "ladder frame group" after lift-off is insufficient. .

Second, the total length is 15 meters, which is extremely unfavorable for driving and operation in the building group.

Third, the wire rope traction will easily cause uneven force on the lifting body. If the gap is too small, it will increase the lifting load. If the gap is too large, it will cause shaking after lifting, resulting in the instability of the whole machine.

Fourth, the "ladder frame group" is located at the rear of the vehicle, which increases the spatial distance between the rescue body and the building, unless the rescue vehicle is approaching the rescue scene in a backward state.

Fifth, when there are many trapped people, this solution cannot make everyone out of the predicament. In the process of waiting for the narrow elevator, people lack enough safe transition space.

The separator 50 is an annular surface with a tip on the upper part. The positions of the two separators 50 correspond to the positions of the guide grooves 18 and are wrapped and guided. The cable 42 and the manhole 11 are respectively provided with telescopic uprights on both sides. The telescopic uprights are composed of an upper upright post 62 and a lower upright post 63 which are sleeved with each other.

The external dimensions of the utility model in the transport state: the width is not more than 2.5 meters, and the height is not more than 4 meters. The lifting capacity of the lifting platform depends on the number of layers and the length of the folding rods of the first hydraulic lift 10. The number of layers is limited by the height of the entire vehicle body, minus the space occupied by the chassis and the lifting platform, the height of the first hydraulic lift 10 is approximately It is 2-2.5 meters, the single-layer height of the folding rod and the width of the channel steel surface, with 20# channel steel as the minimum material selection, and the folding rod is set to 10-12 layers. Taking the 5-meter folding pole as an example, the 10-storey folding pole can lift up to 43 meters, plus the space occupied by the chassis and the lifting platform, the overall height can reach 45 meters after lift-off, which can meet the needs of most floors in urban and rural areas. .

The folding rod of the first hydraulic lift 10 can be welded with double channel steel to buckle and flat steel in the middle to form double cavity square steel, which not only increases its supporting strength, but also does not occupy height space, and its double cavity can also be used as oil, Air, water, and electrical line passages and jackets. When the length of the folding pole is 16 meters, it can be lifted to 158 meters, and the length of the entire car body is about 18 meters.

The rotating platform 3 should not be too long, and the total length of the rotating platform 3 and the counterweight 45 should not exceed 10 meters, so as to ensure the rotation space and flexibility within the building spacing.

Anti-skid patterned steel plates are laid on the rotating platform 3 and the telescopic platform 4 .

The slewing bearing 5 adopts an external tooth type with an outer diameter of 2.4 meters and an inner diameter of about 2 meters. The cavity with an inner diameter of 2 meters is used as the manhole 11 .

The utility model provides 6 kinds of specific implementation manners, which opens up the thinking of the user and increases the choice of implementation. The utility model can deliver more than 10 rescuers to the rescue floor timely and accurately through the rotating platform 3 and the telescopic platform 4 without going through stairs or elevators, thus avoiding the physical strength and time consumption of the rescuers. The utility model reduces the vibration of the platform through the cooperation of the four-claw wedge block and the electromagnet 77, and the self-locking function enhances the working stability and reliability. The center hole of the large-diameter slewing bearing 5 is used as an escape channel, which avoids the frequent lifting of the platform and increases the practicability. Buffer slide 19 and supporting design make vertical high-speed landing a reality. When the hanging cage 58, the hanging box 56 and the car 8 of the present invention fall to the bottom, the distance from the ground is less than 1 meter, and the wheelless step ladders, slides, etc. can easily escape from the ground, so there is no restriction.
