In a preferred embodiment of the present invention, the present invention provide water cannon mounting structure be used for hook and ladder, ascend a height flat In the high lifting kind fire fighting truck such as platform fire fighting truck.Wherein, the work that high lifting kind fire fighting truck generally includes arm support 1 and is connected on arm support 1 Bucket 2, water cannon 3 is in working bucket 2.Referring to figs. 2 and 3, in the mounting structure of the water cannon that the present invention is provided, water cannon 3 passes through Buffer unit 4 is installed in the bottom of working bucket 2.
Can produce deboost while a large amount of water being sprayed at a high speed with foam due to water cannon, in currently existing scheme, water cannon is produced Deboost can be directly transferred on working bucket and arm support, affect gentle support of the arm support to working bucket.The invention of the present invention People summarizes in repeatedly practice operation and is found that this defect, and water cannon is arranged on working bucket by buffer unit in the present invention Bottom so that in the opposition that water cannon is sprayed water or produced during foam, the cushioning effect of buffer unit can be obtained, so as to Reduce the impulsive force being transmitted on arm support, enable arm support smoothly support works bucket, improve the security of work high above the ground.
Referring to Fig. 1 and Fig. 2, buffer unit 4 includes that coaster 41 and buffer 42, coaster 41 can be moved in working bucket 2, delays Rush device to be connected between coaster 41 and working bucket 2, water cannon 3 is fixed on coaster 41.Can be moved by arranging in working bucket 2 Coaster 41, and be provided with buffer 42 between coaster 41 and working bucket 2, so, when water cannon 3 produces active force, sliding Car 41 is hit and moves in working bucket 2 and the realization buffering of compression buffer 42, after the active force that water cannon 3 is produced weakens significantly It is transmitted on arm support 1, the impact that the smooth working of arm support 1 is produced is greatly reduced.In the present invention, using coaster+buffer shape The buffer unit of formula, one side water cannon 3 follow 41 moveable setting of coaster can meet in actual conditions 3 adjustment direction of water cannon and The requirement of position, on the other hand, coaster 41 can make water cannon 3 be transmitted to the effect of arm support 1 with the double buffering effect of buffer 42 Power weakens significantly.It is to be understood that in other embodiments, the form of buffer unit 4 can adopt various suitable types, As long as the active force that produce can water cannon 3 obtains buffering weakening, such as buffer unit 4 only can include being connected to water cannon 3 On buffer 42.
For force analysis when working with reference to the arm support 1 of fire fighting truck, working bucket 2 and water cannon 3, open fire big gun 3 is via slow Impact after rushing the cushioning effect of device 42 to arm support 1 will weaken significantly.
Referring to Fig. 4, arm support 1 is as follows with the stressing conditions of working bucket 2, it is assumed that 3 horizontal-spray of water cannon or foam, smooth working When the power that working bucket 2 is produced of water cannon 3 be F4, direction be level to the right.The active force that working bucket 2 is produced to arm support 1 is F1, square Bottom right in for the bearing of trend along arm support 1, i.e. Fig. 4, is α with horizontal sextant angle, is connected to the end points on turntable 6 with arm support 1 That is O points are fulcrum, then the corresponding arm of forces of F1 are L1.The deadweight of arm support 1 is equivalent to the weight at 1 barycenter of arm support for G1, and direction is vertical Downwards, with O points as fulcrum, the corresponding arm of force is L3;It is F2 to 1 active force of arm support that oil cylinder 7 is stretched in act, and direction is to stretch oil cylinder 7 along act Upper left in flexible direction, as Fig. 4, and horizontal sextant angle β is the corresponding arm of force of fulcrum as L2 with O points.Turntable 6 is to arm support 1 Active force be F3, direction such as upper left in Fig. 4, is γ with horizontal direction angle, and the arm of force with O points as fulcrum is 0.
When 3 steady water spray of water cannon, with O points as fulcrum, the equalising torque of whole arm support 1 has formula one:
F1 × sin α × L1+G1 × L3=F2 × sin β × L2+F3 × sin γ × 0 formula one
Due to arm support 1 to the directed force F 1 ' of working bucket 2 and working bucket 2 to the F1 of arm support 1 reaction force, F1 ' and F1 each other Equal in magnitude in opposite direction.The balance of 2 horizontal direction power of working bucket has formula two:

1/2 × F4 × t1=1/2 × F1 ' × t2 formula four
Now the torque equilibrium equation of arm support 1 is that formula one is still set up, combinatorial formula one and formula four, has formula five:
F2=[(F4 × t1 × tan α × L1)/t2+G1 × L3]/(sin β × L2) formula five
In prior art, not plus during buffer 42, water cannon 3 is t1 to the time of the effect of working bucket 2, the when compole of the t1 Short, arm support 1 is t2 to the time used by the power from plateau to plateau again of working bucket 2.
In the present invention, after adding buffer 42, water cannon 3 is t1 ' to action time of working bucket 2, and the t1 ' is approximately equal to T1, arm support 1 are t2 ' to the time used by the power from plateau to plateau again of working bucket 2, due to the buffering of buffer 42 Effect, the t2 ' are greatly extended compared to t2, at least t2 '=n × t2 (n>20).After adding buffer 42, elevating ram The active force of 7 pairs of arm supports 1 is F2 '.Then there is formula six:
F2 '=[(F4 × t1 × tan α × L1)/(n × t2)+G1 × L3]/(sin β × L2) formula six
Contrast equation five and formula six understand F2 ' < F2, that is, add effect of the elevating ram 7 to arm support 1 after buffer 42 Power reduces, and in other words, act is stretched the stress when water cannon 3 starts water spray of oil cylinder 7 and will also be reduced, and correspondingly, arm support 1 works will more Gently.The consistent level of arm support 1 is relevant with the size of n values, if selecting more preferable buffer 42, n values will be bigger, can make arm support 1 Shake preferably suppressed, so as to the working bucket 2 that is connected with arm support 1 also will be more steady for operation.
