Preferably, the positioning block is shaped as a wedge.

Preferably, the left side and the right side of the rotating shaft are provided with slots.

The lower part of the aerial ladder is provided with a rotary table, and the rotary table is provided with a wedge-shaped positioning block which is correspondingly inserted into the slots at two sides of the aerial ladder rotating shaft. The scaling ladder uses the pivot as the center rotation, and the locating piece moves down during rotatory, and when rotating slot position, the locating piece moves up under reset spring's effort, inserts corresponding slot to realize scaling ladder luffing motion's locate function.

Preferably, each side of the rotating shaft is provided with not less than 3 slots. More preferably, the slots are arranged in a 30-degree rotation array with the axis of the rotating shaft as the center of the circle.

When 3 slots are arranged on each side of the rotating shaft, the slots are in 30-degree rotation array market by taking the axis of the rotating shaft as the center of a circle, the scaling ladder is rotated to 30-degree positioning once from the initial position and 60-degree positioning once, the maximum rotation angle is 60 degrees, and the positioning is performed twice in total.

Further, the carousel sets up to the gear form, the automobile body is provided with the carousel setting element, the carousel setting element is provided with the most advanced with carousel tooth's socket looks adaptation.

Preferably, the turntable positioning element has a certain elasticity.

Has the advantages that:

the utility model has higher playability and interest, and realizes the positioning function of the aerial ladder by the matching of the slot arranged on the aerial ladder rotating shaft and the positioning block of the turntable; set up gear form carousel through the revolving stage below, the automobile body sets up the most advanced and carousel tooth's socket adaptation of carousel setting element, and when the aerial ladder horizontal hunting, the carousel is along with rotating, and the carousel setting element relies on elasticity itself to come and go, the fixed tooth's socket that rotates the carousel with most advanced simultaneously to realize aerial ladder horizontal hunting's locate function.

Detailed Description

The present invention will be described in detail with reference to the following embodiments and accompanying drawings.

Example (b):

the aerial ladder positioning device of the fire fighting truck shown in fig. 1-3 comprises an aerial ladder 1, a positioning table and a truck body 8, wherein the positioning table comprises a rotary table 2 and a rotary table 3, the rotary table 3 is arranged below the rotary table 2, the rotary table 3 is fixedly connected with the rotary table 2, the positioning table is connected with the truck body 8, and the aerial ladder 1 is connected with the rotary table 2; the turntable 2 is provided with a wedge-shaped positioning block 4, and a return spring 5 is arranged below the positioning block 4; the aerial ladder 1 is provided with a rotating shaft 6 and a rotary table 2, wherein the surface of the rotating shaft 6 is provided with a slot 7 matched with the positioning block 4. Slots 7 are formed in the left side and the right side of the rotating shaft 6; and the number of the slots 7 on each side of the rotating shaft 6 is not less than 3.

As shown in fig. 4, 3 slots 7 are provided on each side of the rotating shaft, and the slots 7 are arranged in a 30-degree rotating array with the axis of the rotating shaft 6 as the center. The scaling ladder 1 rotates by taking the rotating shaft 6 as a center, the positioning block 4 moves downwards during rotation, and when the rotating angle reaches 30 degrees, the positioning block 4 moves upwards under the acting force of the reset spring 5 and is inserted into the corresponding slot 7, so that the positioning function of the up-and-down swing of the scaling ladder 1 is realized. The aerial ladder 1 is rotated to 30 degrees from the initial position for positioning once, is rotated to 60 degrees for positioning once, and is rotated to 60 degrees at the maximum angle for positioning twice in total.

As shown in fig. 5, the turntable 3 is provided with a gear, the vehicle body 8 is provided with a turntable positioning member 9, and the turntable positioning member 9 is provided with a tip end adapted to the tooth space of the turntable 3. The turntable positioning member 9 has a certain elasticity. When the scaling ladder 1 swings left and right, the turntable 3 rotates, and meanwhile, the turntable positioning piece 9 reciprocates at the tip end by virtue of the elasticity of the turntable positioning piece and fixes the tooth grooves of the turntable 3, so that the function of positioning the scaling ladder 1 by swinging left and right is realized.

Finally, it should be noted that: it should be understood that the above examples are only for clearly illustrating the present invention and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious changes and modifications may be made without departing from the scope of the present invention.
