circuits.Hydraulic pressure system, oil hydraulic system, telescopic arm, people's frame and weight system horizontal operation principle and operation program it is as follows：When telescopic arm is in double dot dash line state clinostatism shown in Fig. 1, closing presure water valve 14, start variable water pump 29-1, check valve 118 is obstructed, open two position three-way valve 119 and arrive shown position, press water in (see Figure 12), accumulator 35 ' flows to accumulator 12 through flexible water pipe 42,43,45,47,50,52,55,57,20, limbers 60 ' and flexible pipe 104-1, check valve 102, uniform-pressure-drop valve 100 and four-way connection 111.Now, the left and right water route of four-way connection 111 is obstructed, and accumulator 12 is filled to level pressure, variable water pump 29-1 to limiting after pressure, and its flow reduces the dry run state that levels off to, and hydraulic pressure system completes the state of the storage or saving press water energy of accumulator 12.Then quantitative oil pump 30 is started (see Figure 13), three-position four-way valve 125 is reached into the right left position oil circuit, pressure oil is through three-position four-way valve 125, adjustable throttle valve 126 (now a roads are obstructed) enters the piston-less lumen of oil cylinder 35 and oil cylinder 25 through C roads, there is the oil of rod end chamber not through unidirectional 127 and 130, oil circuit C1, b, three-position four-way valve 125 flow back to fuel tank 116 '.Now (see Fig. 1), the piston rod of oil cylinder 35 and oil cylinder 25 is released simultaneously, base arm 1 ' is holded up, exhibition is vertical upwards for bent semi-girder 1, at the same time (see Fig. 8,9,12,13), the drive lever of weight 16 shifting fork 15 dials up the valve rod 92 of three-position four-way valve 17, the press water of accumulator 12 passes through four-way connection 111, three-position four-way valve 17, flexible pipe 104-2, hydraulic motor 18, and driving worm screw 10 drives worm gear 11 by people's frame steering horizontal position.After pressure water-driven hydraulic motor 18 does work, through flexible pipe 104-2, the row of three-position four-way valve 17 to air.This process is until the piston rod of (see Figure 13) oil cylinder 35 and cylinder 25 is untill final position, telescopic arm completion base arm are holded up, bent semi-girder is opened up immediately, when piston-less lumen, i.e. a road binders pressure are increased to the pressure value of the setting of sequence valve 131, pressure oil flows to oil cylinder 36 ', 36 through sequence valve 131 " piston-less lumen, have rod end chamber oil flow back to fuel tank 116 ' through check valve 133 and c1, b road, three-position four-way valve 125.The now pressure rise of retaining mechanism 37 ' and 37 " locking (see Fig. 1,14,17,18) when oil cylinder 36 ', 36 " piston-less lumens to sequence valve 136 setting when, pressure oil footpath sequence valve 136 flows into the piston-less lumen of oil cylinder 22, bent semi-girder is begun to ramp up, when being increased to required height (but highest order is not arrived, that is the piston of oil cylinder 22 does not arrive top dead-centre) three-position four-way valve can be pulled to middle position, bent semi-girder component stops rising, when pressure continues to rise to 122 setting of safety overflow valve, pressure oil flows back to fuel tank 116 ' through it.Now people's frame stops height herein.At the same time (see Figure 12), the valve rod 92 of three-position four-way valve 17 is pushed middle position by weight 16 by lever shifting fork 15, and the path choke-out of hydraulic motor 18, people's frame 13 keeps horizontality.Because the lift of telescopic arm is very high, people's frame is difficult to contact building, fire fighter dials up the press water of three-position four-way valve 110 (see Fig. 8,9,12) accumulator 12 through four-way connection 111, three-position four-way valve 110 enters the piston-less lumen of hydraulic cylinder 93, and driving piston pole socket 95 drives telescopic frame 13-2 to stretch to building.When fire fighter opens pressure water valve 14 in people's frame, start quantitative water pump 29-2, variable water pump 29-1 also arrives big flow, and press water is sprayed at the water that goes out by check valve 118, two position two-way valve 119, flexible water pipe 42-20, limbers 60, flexible pipe 101, pressure water valve 14 and fire-fighting pressure water spray gun 98.In the process, uniform-pressure-drop valve 100 can automatically turn on the press water of compensation energy accumulator 12.When that must decline (see Figure 13), three-position four-way valve is moved to right position to the left, pressure oil footpath three-position four-way valve 125, oil circuit b, (c1 is obstructed) c2 has piston thick stick chamber to oil cylinder 22, the oil of piston-less lumen is through check valve 135, oil circuit a, choke valve 126, three-position four-way valve 125 flows back to fuel tank, when the piston of oil cylinder 22 is to bottom dead centre, when system oil pressure is increased to the setting of sequence valve 134, pressure oil is through C1 roads, sequence valve 134, oil cylinder 36 " have rod end chamber and, oil cylinder 36 ' has rod end chamber, 36 ' and 36 " oil of piston-less lumen is through check valve 132, oil circuit a choke valves 126, three-position four-way valve 125 flows back to fuel tank, now retaining mechanism unclamps, when oil cylinder 36 ", when 36 ' piston is to bottom dead centre, system oil pressure continues to rise to sequence valve 128, during 129 setting, pressure oil is through three-position four-way valve 125, oil circuit b, c1, there is rod end chamber into oil cylinder 35 through sequence valve 128 all the way, there is rod end chamber on another road through sequence valve 129 into oil cylinder 25.The oil of two oil cylinder piston-less lumens through oil circuit C, choke valve 126, three-position four-way valve 125, flow back to fuel tank 116 ', now bent semi-girder crank arm, base arm clinostatism, when two oil cylinder pistons are to final position, telescopic arm be clinostatism in place, the position as shown in double dot dash line in Fig. 1.While above-mentioned bent each component retraction of semi-girder is cranked arm with base arm clinostatism, weight 16 reversely stirs three-position four-way valve 17 by lever shifting fork 15, the press water of accumulator 12 passes through four-way connection 111, three-position four-way valve 17, hydraulic motor 18, flexible pipe 104-2 (see Fig. 9), the row of three-position four-way valve 17 are to air, and reverse drive hydraulic motor 18 drives worm screw 10, worm gear 11 reversely to adjust the levelness of people's frame untill the double dot dash line horizontal level shown in Fig. 1.Above-mentioned base arm is holded up, the exhibition of bent semi-girder is vertical, and clamp system is clamped, and component stretchings, component retraction, clamp system is unclamped, song semi-girder is cranked arm, during base arm clinostatism, the aperture (see Figure 13) of adjustable throttle valve 125 can be adjusted, the speed governing during realizing respectively.Hydraulic circuit shown in Figure 13 ensure that sequentially-operating：Oil cylinder 35 and the piston rod of oil cylinder 25 are extended to final position --- oil cylinder 36 ', 36 " clamp after the commutation of --- piston rod of oil cylinder 22, which is extended to, needs position --- three-position four-way valve; the piston rod of oil cylinder 22 is inside contracted --- oil cylinder 36 ', 36 " piston rod is inside contracted, clamp system unclamps --- and oil cylinder 35 and the piston rod of oil cylinder 25 are inside contracted, this ensure that (see Fig. 1) base is holded up, after bent semi-girder exhibition is stood in place, clamp system is just clamped, after clamping in place, bent semi-girder 2-9 sections component could stretch out；Must be that bent semi-girder 2-9 saves component retraction in place during withdrawal, clamping cylinder could unclamp, and unclamp in place, bent semi-girder can just crank arm, and base arm could clinostatism.Whole action process ensure that the center of gravity of telescopic arm falls in car body bearing surface all the time, will not occur tipping.20 be the most upper flexible water pipe of section in Figure 11, and 20 ' be water pipe head, and the two is mutually welded, and 40 be flexible water pipe flange (see Fig. 2), and its endoporus is mutually welded with water pipe head, and 113 be thrust washer.115 be sealing ring, it is separated by dress with thrust washer 113,114 be adjusting nut, screw in the internal thread of water pipe head 20 ', 57 are loaded into the flexible water pipe of next sections of water pipe head 20 ', turn adjusting
