Described buffer over the ground is mounted in the tire below the outer cover;
The structure of described suspention buffer as shown in Figure 3 and Figure 4, it is made up of suspension ring 1, pull bar 2, doubler 3, pull bar lead segment 4, ultimate load limiting device 5, freight container guide plate 6, the vertical framework 7 of freight container, freight container force bearing plate 8; The be connected pull bar 2 of suspension ring 1 of two upper ends inserts in the hole of the freight container force bearing plate 8 that is clipped between the vertical framework 7 of freight container and freight container guide plate 6, be with spring on the pull bar 2 between freight container force bearing plate 8 and the freight container guide plate 6, pull bar 2 terminations that are passed down through freight container force bearing plate 8 and freight container guide plate 6 are fixed with ultimate load limiting device 5; Two pull bars 2 are isometric, but misplace side by side up and down, and the spring of the pull bar 2 that the position is low is longer than the spring of the high pull bar in position 2.
Suspention buffer principle of work
Coil spring is enclosed within outside the pull bar 2, and the pull bar top is provided with suspension ring 1, and the below is for to execute power-assisted doubler 3 to spring.Spring outside is and the vertical framework 7 end face bonded assembly sleeves of freight container, and there is the load lid of annular the sleeve upper end, the spring solid pressure in sleeve.
Opposite process when descending, takes place from the limes superiors position in suspension ring 1, pull bar 2 and doubler 3.
Under the condition that is provided with the suspention bumper, freight container is hung in the ground-surface process, the tension force that lifting rope makes progress is delivered on the freight container by spring, the size of the power of spring transmission is directly proportional with the compression of spring amount, the power that freight container is subjected to strengthens gradually with the increasing gradually of amount of spring compression, freight container reduces gradually to ground-surface pressure, when the compression of spring amount reaches the corresponding amount of compression of gravity with freight container, the power of transmitting equals the gravity of freight container, ground-surface pressure is equalled zero, and freight container begins to break away from ground.During smooth flight, tension force equals gravity, and the compression of spring amount keeps and the cooresponding amount of compression of gravity.The process opposite with the lifting process takes place when freight container is put down ground: begin the instantaneous of kiss the earth, freight container also by through the spring transmission equal suspending in midair of gravity, ground is not under pressure; Discharge lifting rope downwards with helicopter, the compression of spring amount discharges gradually, the power that makes progress that power of transmitting and freight container obtain reduces gradually, the tension force of lifting rope reduces gradually, the pressure that ground is subjected to strengthens gradually, lax fully up to spring, the power that makes progress that the power of transmission and freight container obtain equals zero, and the gravity of freight container is pressed on the ground fully.Because general select softer of the spring of buffer, the compression stroke of the gravity of corresponding its maximal work compression machine freight container is generally bigger.The design's compression stroke is made as 70 millimeters.Before compression stroke does not discharge fully, lifting rope can not relax moment, the also impossible pop-off of its tension force, thereby the power between freight container and the ground also can not be added to maximum in moment, but in the process that the compression stroke of recoil spring discharges gradually, strengthen gradually, thereby reduced ground-surface bump has been played the effect of bumper and absorbing shock.
The force analysis of buffer
The bumper and absorbing shock system of freight container intends adopting the spiral compression spring formula buffer that is located at the freight container top, and scheme drawing is seen Fig. 3.
As shown in the figure, suspension ring-duplex pull rod-doubler applies power to spring; Compression spring set is formed (spring wire diameter 12mm by totally four compression springs of suit in twos, footpath 50mm in the inner spring, footpath 80mm in the outer spring, 14 circles, drift 260mm, free state helical pitch 17.3mm, ultimate load is respectively 7688N and 5433N, individual pen amount of compression 4.728mm under the ultimate load), upwards power transmission; The last longeron below of freight container is welded with force bearing plate, accepts the power that spring transmits.Be welded with guide plate on last two longerons, force bearing plate and guide plate have two pairs of coaxial guide holes, in order to guide duplex pull rod and to bear the moment that may occur.

The specific embodiment
Embodiment. this example is the helicopter handling freight container of a test.Its structure mainly is made up of outer cover, support guiding location and restraint device, auxiliary load spare, force transmission element and attaching parts 3 partial function assemblies as shown in Figure 1.In the interior part multilayer shelf of freight container outer cover and the level and the position of various device, and do not have on the individual frame and the outer cover inwall on fixing a plurality of hooks.
The structure of outer cover comprises fixing base plate, the gable board of end face, folding oblique top plate and vertical wallboard; Wherein, the base plate steel plate, gable board, oblique top plate and vertical wallboard are made frame and strengthening rib strip by aluminium section bar.
Fixing plate can rely on corresponding load-bearing frame: gable board is fixed on the side of vertical framework; Base plate is fixed on the last plane of two underframes.
Outer cover outer surface has smooth, corrosion stability; Certain rigidity is arranged, damping is arranged, not flutter under the effect of air-flow; Good sand and dust leak tightness is arranged; Easy to operate, light deadweight is little.
The freight container outer cover has five plane frameworks: four levels with one vertical.Wherein the load of four horizontal frames is as follows:
Preceding lower floor framework is of a size of 2400 * 1000mm, and loading is 560kg;
Back lower floor framework is of a size of 2400 * 1000mm, loads to be 600kg;
Preceding upper strata framework is of a size of 2400 * 00mm, loads to be 215kg;
Back upper strata framework is of a size of 1400 * 900mm, loads to be 150kg.
Four horizontal frames are the flexural loading form at vertical and horizontal, make whole plain bending.Though four horizontal frames are upper and lower layer structure, are all to be the parallel subordinate of vertical framework from the power transmission route.Wherein bear the heaviest front and back lower floor framework of load, inboard be supported on vertical framework on the crossbeam of below along total length, two ends, the outside have under the condition of the support of oblique straining beam, the support that there is oblique rope the centre, and length is divided into two and strides longitudinally, laterally become two fulcrum single supported beams, rather than cantilever beam.Therefore its load intensity is little, and the load of upper strata, front and back framework is littler.
The perpendicular framework is welded into by many levelling pipes, three VERTICAL TUBE and two inclined tubes, the power that it is suffered, a part just in frame plane, the power of another part as transmitting from oblique rope, component perpendicular to frame plane is arranged, but cancel each other before and after most of.
The main body load larrying member: vertically framework and two heavier following horizontal support frameworks of load are welded by rectangular tube.Two lighter last horizontal support frameworks of load then are welded by angle steel, and the angle steel of each support location guide function also has the powerful of adding simultaneously.
The angle steel of selecting the rectangular tube of 60 * 40 * 3.5mm and 40 * 40 * 4mm for use is as main structural materials, and the face horizontal positioned of the long limit 60mm of broad, doing directly is the positioning supports face.
The inboard of four horizontal support frameworks is connected with vertical framework with hinge, and the outside then is connected with vertical framework by the digonal link that is subjected to pulling force.In addition, for reducing span, be added with oblique rope in the midpoint of span and be connected with vertical framework.
In the interior part multilayer shelf of freight container outer cover and the level and the position of various device, specifically:
A, consumptive object all is placed near the vertical inboard of frame, helps reducing fore-and-aft direction or horizontal influence;
B, be provided with two redundant cover semidefinite position pinch devices for standby short tube, change the placement location of residue short tube on demand, can adjust the balance of longitudinal direction; All be provided with more suspension hook in the both sides, front and back for flexible pipe, cable, small tools or other foreign material, change the quality of suspending in midair on the suspension hook, can adjust the balance of both direction in length and breadth;
C, in addition changes the horizontal position of ocean king's electrical generator, changes the flodlit support in the position of vertical and horizontal, also can play certain corrective action.
For the barycenter of lower floor before making near midway location, the Honda electrical generator of the 210kg that weighs is arranged in the only inboard of the manual oil well pump of 30kg of weight; Preceding lower floor is alto object, altitude range 650-800mm; The top is fit to establish the upper strata.
To arrange all remaining rush repair equipments of not arranging as yet at the rear portion, except that several rush repair equipments, comprise the standby pipes of six kinds of different bores; Arrangement layer has only two fire extinguishers on the back; Fire extinguisher is a kind of very special very important again equipment, need not take under no fire alarm situation, in case occur must using fast again under the fire alarm situation; Arrangement design to fire extinguisher has given special concern.
Two fire extinguishers are placed on the angle steel welded structure support, and leading dimensions is 1000 * 475 * 980mm, comprise that the total mass of the about 35kg of support quality reaches 155kg, and it is big to take up room, and moves effort; Two fire extinguishers are located by two concave arc shape locating pieces, by two covers can not quick operating plain screw press plate mechanism in the face of arranging to be pressed on the both sides of the support that an angle steel is welded into; Press plate mechanism is comparatively simple and crude, must slowly unclamp and screw off nut and just can take off pressing plate, and the loading and unloading fire extinguisher is extremely inconvenient.
If remain untouched two fire extinguishers of belt supporting frame are arranged as a handling object, though save trouble most in the design, the simplest, but obviously be very irrational: original every fire extinguisher self has had vehicle frame and the wheel of oneself, promote flexiblely, mixing for two fire extinguishers and having put up does not have wheel to move the weight of inconvenience; Joining the 3rd cover support frame and positioning compression device for it again on the freight container not only will be heavy more, must operate two-layer three and overlap and compress mechanism just to take two such operating process of fire extinguisher must be to waste time and energy; In freight container, must consider that fire extinguisher and the structure of freight container itself and the position of other handling object concern: when fire extinguisher is on the shelf at ordinary times, need not to move also and should not hinder conveniently taking of other object; Urgent need the time should not be subjected to not taken, still in position other objects stop obstruction; Always having a residing position in two fire extinguishers that place on the opposite more is awkward.
In order to address this problem, remove former support among the design, two fire extinguishers are with the position of most convenient, placed side by side and be pressed on framework top, upper strata, back with interlock piece relief panel, not only take up room and be kept to 82 * 450 * 940mm, quality reduces about 35kg, the more important thing is to we can say and do not hinder taking of miscellaneous equipment instrument satisfactoryly when having accomplished need not take under the normal circumstances; In emergency circumstances be not subjected to the obstruction that stops of other object, the harsh requirement that can extremely fast take:, do not hinder other facility to take owing to be placed on the top; When taking, only need loose slightly nut can open pressing plate fast, easily take off the only fire extinguisher of 60kg of two separate unit weight simultaneously from the place ahead by two people.Although be the upper strata framework, actual height is not high, the below is highly only be that the Honda self power generation welding generator of 500mm, the place ahead also have length to reach 870mm, width and be 410mm, highly only be that the firm steady tool box that 380mm, quality reach 200kg can be filled the post of stretcher completely.
Be placed on each collection dress object analysis of back lower floor:
(1) the tool box casing is for being 870 * 410 * 380mm, the iron sheet casing, and no pulley, weight is bigger, moves effort, should be arranged in lower floor; Can pick and place the instrument that will use as long as open case lid, the position of placement should not hinder picking and placeing of other equipment tool.Case lid will upwardly open around the hinge on length limit, rear, and covering is not preferably blocked by the support on upper strata in the top, otherwise requires the upper strata framework to leave very big distance; The height of casing has only 380mm, the casing comparatively robust, and bigger weight can be born in the plane on the case lid, and the top has than large space, so can be used as the stand-by platform of placing motor-driven weight outside the plan, also can do step and pedal when moving fire extinguisher;
(2) Honda self power generation welding generator contour dimension is 780 * 510 * 500mm, and quality is 100kg, and is bigger than normal in the quality in highly less object; Generally need not move, only need current delivery be arrived electrode holder, so be placed on the below of upper strata, back framework by cable;
(3) the anti-explosion electric oil well pump surrounds protection by the oblong structural steel frame, the length of side of framework is 1130 * 540 * 1000mm, quality is 135kg, specific mass is less mutually with standby short tube, so it is placed on the outside of short tube, comparatively favourable to reducing the suffered moment of back underframe with the lack of balance that reduces both sides, freight container front and back; The chamfering of usefulness is guided at connected to chassis rectangular steel pipe two ends, below in addition, thus when moving preferably along long side direction vertical push-and-pull of lower floor support frame afterwards, more laborsaving, therefore, stand frame is furnished with longitudinally rectangular tube as its support and guiding at this place;
(4) prerotator surrounds protection by angle iron frame, and the length of side of framework is 800 * 370 * 910mm, and is preferably along the horizontal push-and-pull of long side direction stand frame, more laborsaving when moving; Therefore, stand frame is furnished with horizontal rectangular tube at this place;
(5) standby short tube totally six kinds of bores (external diameter is respectively 457mm, 323mm, 273mm, 219mm, 168mm, 159mm), length is 1m, each total weight of one is 311kg, and is still very heavy; One end has processed the intersection that passes through mutually with the main line of external diameter 508mm.
Standby short tube is consumptive at random equipment, will be with when transporting entirely, just no longer takes back for some that use up during return, and weight and centroid position all can change.
Originally short tube is that attitude with level is deposited on the big frame that is placed in the angle iron frame in the warehouse, when going out open-air repairing framework is hung on the transportation means from the big frame release warehouse of hanging oneself down again.Framework deadweight is bigger, if the pipe of the specification that need take is crushed on when following, just has to move earlier and then moves back to top all pipes; Even the pipe that has size suit, take bassoon also have to extract out earlier cover inside tubule and then put back to, extremely inconvenient.
From laying and take convenient and strength-saving angle, short tube changes with vertical attitude size suit, all is provided with the isolation locations up and down, and the pipe of suit is kept apart mutually.
Each repairing task may need more than one of the pipe of certain specification, and the pipe of some other specifications does not need.Therefore, the quantity of isolating locations should be provided with many covers, and certain alerting ability is arranged.
The pipe wall thickness is 7.1mm, and the feasibility analysis of its internal diameter and suit sees Table 1.
The mutual suit feasibility of the standby pipe of the different bores of table 1
As can be known from the above table, at first, can suit between the fwd Pyatyi, having only minimum 159mm and the one-sided gap of previous stage 168mm is negative value, and tightness is promptly arranged, impossible suit.
Secondly, one-sided gap minimum between the outer wall of the inwall of upper class pipe and next stage pipe is 17.9mm, and finger can stretch into, and isolating locations also can have enough thickness and intensity.If the pipe of suit is not to be placed on same height, but its high more segment distance in upper end of more little pipe is more convenient for taking.
This explanation one cover is isolated the locating surface that locations should also may be provided with whole six kinds of specification pipes, five pipes of portability.
When three cover isolation locationss were set, portable maximum standby pipes number was: preceding four kinds of specifications, each three; Two kinds of specifications of 168mm and/or 159mm, totally three.When certain specification pipe need carry more for a long time, can be placed on other positions, for example the tool box covers.
The bumper and absorbing shock system of freight container adopts the spiral compression spring formula buffer that is located at the freight container top, its structure as shown in Figure 3 and Figure 4, it is made of side by side two compression spring buffers, and be installed in the both sides of the vertical framework 9 of freight container, every compression spring buffer is that the upper end has the pull bar 2 of suspension ring 1 to put the compression spring 4 bottoms pull bar lead segment 4 that is connected again behind the afterburning dish 5 that is connected, sleeve 6 is inserted in the back, the upper end of sleeve 6 is Gu Fenghuangai again, make pull bar 2, compression spring 4, afterburning dish 5 is enclosed in 6 li in sleeve, and pull bar lead segment 4 is stretched out sleeve 6, and connects ultimate load limiting device 5 after passing freight container guide plate 6; The pull bar 2 of these two compression spring buffers and the equal in length of pull bar lead segment 4, but one is long and the other is short for sleeve 6, the long compression spring buffers of sleeve 6 come the short compression spring buffer of sleeve 6 on the lower side, mutually the upper end of back two sleeves 6 is on a horizon side by side, and the length difference of freight container guide plate 6 is stretched out in the lower end;
The force analysis of buffer
Suspension ring-duplex pull rod-doubler applies power to spring; Compression spring set is formed (spring wire diameter 12mm by totally four compression springs of suit in twos, footpath 50mm in the inner spring, footpath 80mm in the outer spring, 14 circles, drift 260mm, free state helical pitch 17.3mm, ultimate load is respectively 7688N and 5433N, individual pen amount of compression 4.728mm under the ultimate load), upwards power transmission; The last longeron below of freight container is welded with force bearing plate, accepts the power that spring transmits.Be welded with guide plate on last two longerons, force bearing plate and guide plate have two pairs of coaxial guide holes, in order to guide duplex pull rod and to bear the moment that may occur.
The analytical calculation of energy disperser is described as follows:
Maximal work load=2 * (the 7688+5433)=26242N=2574kgf of four springs
Amount of compression under the ultimate load=14 * 4.728=66mm.
Listed handling object quality=1531kg in the table, reserving may load mass 300kg, the about 300kg of tare mass of freight container quality.Maximum load quality 1531+300+300=2131kg is less than maximal work load.
The acceleration/accel 2574/2131=1.2g that recoil spring is allowed.
Acceleration/accel in the practical flight may damage because of overload for preventing spring greater than 1.2, should establish the ultimate load limiting device, and when overload, limiting device contacts with guide plate, and the part of overload is no longer through the spring transmission.
This example is through on probation, and the freight container center of gravity disposes rationally, the docking facility fixation, and access is convenient, and the helicopter handling is steady, and landing does not have impact, and is fast to pipeline dimension repairing speed, for new way has been opened up in the dimension repairing of oil and gas pipes.
