Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.As shown in Figure 1, Figure 2, Figure 3, Figure 4: the vehicle-mounted aerial ladder dolly of a kind of fire fighting truck, comprise car body 1, multiple support 2 is provided with side by side in the bottom of car body 1, multiple shock-absorbing spring 11 is also distributed with equably between car body 1 and support 2, roller structure 3 is connected at the two ends slip cap of support 2, each roller structure 3 can both relative to the axial float of support 2, baffle plate 14 is provided with in support 2, crossed strip 15 is then provided with between baffle plate 14 and roller structure 3, under the effect of crossed strip 15, roller structure 3 can remain outside pressure, each roller structure 3 is made up of two symmetrically arranged rollers 4, and match with roller structure 3 be provided with slideway 5, two above-mentioned rollers 4 lay respectively at the both sides of slideway 5, and are clamped, described slideway 5 is connected to form successively by many points of slideways 7, these point of slideway 7 is positioned at the outside of aerial ladder telescopic arm 6, described aerial ladder telescopic arm 6 is two that arrange in pairs, each root is all made up of the more piece be mutually socketed, brace summer 8 is all provided with between each joint of two aerial ladder telescopic arms 6, brace summer 8 is provided with fixed pulley 9, hawser 10 is connected with in the front end of car body 1, be connected with the winding plant on fire fighting truck after fixed pulley 9 walked around by this hawser 10, the gripper shoe of described car body 1 inside (to be namely positioned at bottom car body 1 and be used for the plate construction of carrying personnel or fire-fighting equipment) is made up of multiple base plate be set up in parallel, each base plate is supported on the framework of car body 1 by axis of rotation, the end of rotating shaft is provided with turbine 13, what match with all turbines 13 is provided with the screw rod 12 of rotating support in car body 1 outside all simultaneously.
The course of work of the fire fighting truck vehicle-mounted aerial ladder dolly of the embodiment of the present invention is as follows: when the condition of a fire appears in high-rise, when needing to use the fire fighting truck being configured with the dolly of this kind of version to put out a fire, first aerial ladder telescopic arm 6 is allowed to stretch out, all point slideways 7 are connected to the complete slideway 5 of the outer formation one of aerial ladder telescopic arm 6 in turn, then the winding plant on fire fighting truck is started, under the effect of winding plant, around the hawser on fixed pulley 9 can blue Dong's car body 1 on aerial ladder telescopic arm 6 along slideway 5 upward sliding, the roller structure 3 of overall process medium-height trestle 2 bottom of sliding is clamped in slideway 5 both sides all the time, play the effect connected with guiding, and along with the continuous rising of car body 1, spacing between two slideways 5 of support car body 1 also can constantly become large, but due to the existence of crossed strip 15, roller structure 3 can make adaptive adjustment according to the spacing between slideway 5, ensure that roller structure 3 is connected all the time with between slideway 5, under the traction of hawser 10, car body 1 can run to the top of aerial ladder telescopic arm 6, close point of origin place always, fire fighter in car body 1 can implement fire-fighting work, also trapped personnel can be allowed to move in car body 1, and winding plant rotates backward, progressively veer 10, car body 1 is allowed to slide along aerial ladder telescopic arm 6, be transported on ground by trapped personnel, and now aerial ladder telescopic arm 6 is still in the state of stretching out, fire fighter can utilize the fire-fighting equipment that aerial ladder telescopic arm 6 loads to carry out fire-fighting work, namely car body 1 back and forth can transport on aerial ladder telescopic arm 6, realizes upwards transporting fire-fighting equipment, rescue apparatus, the object of conveying trapped personnel downwards, although do not connect between point slideway 7, and certain radial difference can be there is between the axis of adjacent point slideway 7, but this difference is relatively little, therefore can't affect coordinating between roller structure 3 with slideway 5, the multiple shock-absorbing springs 11 arranged between car body 1 and support 2 then can reduce, even eliminate the vibration produced in car body 1 motion process, after the telescopic arm of aerial ladder has set up, need before car body 1 moves to telescopic arm top, car body 1 can be adjusted according to the angle of inclination of telescopic arm, concrete adjustment process is as follows: rotating screw bolt 12, all identical angle can be rotated under the effect of screw rod 12 with all turbines 13 that screw rod 12 matches, and then drive base plate also to rotate certain angle, all base plates are allowed to turn to the state paralleled with ground, even if car body 1 remains inclination in reciprocating process on aerial ladder telescopic arm 6 like this, but the base plate of carrying personnel and equipment also can remain level.
