The inside；Gas storehouse 41 is passed in and out in the outermost end in ventilation storehouse 31, vertical air vent 42 and cross scavenging hole 43, vertical air vent are installed
42 stand on the top of disengaging gas storehouse 41, and cross scavenging hole 43 is transversely mounted on the outside of disengaging gas storehouse 41；It is constructed by these, it is right
Active force from upper level carries out the pressure-reducing cushioning effect of multi-layer, is allowed to form a more complete third level damping slow
Punch mechanism.
Technical controlling principle: when the synergy pressure from patient body weight and the self weight of emergency bed upper body part is being subtracted
It shakes in 1 pressure-reducing cushioning of cylinder assembly, a part of active force is passed to by hydraulic oil in damping storehouse 11, by hydraulic oil pipe 4, is transferred the files out
Pass 45 and the second hydraulic oil pipe joint 24 are transmitted to buffer pressure-reducing device 2 and enter the hydraulic oil effect storehouse 18 full of hydraulic oil, because
Hydraulic oil acts on storehouse 18 and constructs reason, and the active force compressing for acting on hydraulic oil pushes the tip portion of decompression piston 19 in piston
It takes exercises in cylinder body 20, while thick end portion moves in decompression storehouse 25.When 19 thick end portion of decompression piston is in decompression storehouse 25
When taking exercises, just to oppress relief spring 26 and do pressure-reducing cushioning movement, the weak property relief spring 27 of relief spring 26 first receives compressing,
After compressing to a certain extent, epistasis relief spring 28 is also squeezed, and when active force is smaller, weak property relief spring 27 cooperates
Higher level's pressure-reducing cushioning system plays the role of good pressure-reducing cushioning, and when active force is larger, weak property relief spring 27 is sometimes just straight
It connects and is forced into bottom, lose pressure-reducing cushioning ability, epistasis relief spring 28 takes over force fit higher level's pressure-reducing cushioning system at this time
System plays the role of good pressure-reducing cushioning, and the active force that higher level's buffering depressurized is carried out buffering decompression again like this, from
And reach and further slow down the emergency bed shock effect power of jolting that patient generates because walking in roughness pavement of carrying a load on the back, it is formed
Mutually matched combined shock absorption combination unit.As decompression piston 19 is oppressed or is rebounded back and forth by hydraulic oil and relief spring 26,
Space in decompression storehouse 25 becomes smaller or expands rapidly therewith, and air moves back and forth also with decompression piston 19 and quickly passes through and change
Port 30 is discharged or is inhaled into.It is empty when decompression piston 19 oppresses relief spring 26, and the space in decompression storehouse 25 is caused to become smaller
Gas is quickly urged into the air inlet and exhaust valve storehouse 32 in ventilation storehouse 31 by ventilation mouth 30, under certain exhaust force, rapidly
Air outlet valve 33 is opened, disengaging gas storehouse 41 is entered by the thin filter screen 39 and coarse filtration net 37 of filtering cabin 36, then pass through disengaging gas
The vertical air vent 42 in storehouse 41 and cross scavenging hole 43 are discharged except buffer pressure-reducing device 2；When decompression piston 19 is depressurized spring 26
When the space that rebound leads to depressurize in storehouse 25 becomes larger, air vertically the changing by disengaging gas storehouse 41 of 2 outside of buffer pressure-reducing device
Stomata 42 and cross scavenging hole 43 are sucked into coarse filtration net 37 and thin filter screen 39 into filtering cabin 36, after filtration, purification,
Air inlet and exhaust valve storehouse 32 is entered back into, under certain suction effort, air opens intake valve 35, then is quickly inhaled by mouth 30 of taking a breath
Into in decompression storehouse 25.
3, the composition, function and technical controlling principle of shifting switch device 3
Referring to Fig. 5, the hydraulic oil of the shifting switch 45 of the device and the damping storehouse 11 of damping cylinder assembly 1 and buffer pressure-reducing device 2
Effect has the hydraulic oil pipe 4 full of hydraulic oil to be connected between storehouse 18, is fixedly mounted on emergency bed by fixing piece 46 convenient for medical care
Personnel quickly adjust the position of conversion.Shifting switch 45 is divided for 0 gear, I gear, II gear and III gear, and 0 gear is to close to subtract
Shake state can make a whole set of damping device lose shock-absorbing function, and, patient body weight smooth suitable for evenness of road surface subtracts more than emergency bed
It shakes (device temporarily sets 200 ㎏) of the device damping limit and is not suitable for the scene for carrying out damping transport to patient；I gear is to open
Logical one third state, to overweight of carrying a load on the back but without (temporarily 150 ㎏ of setting --- the 200 ㎏'s) disease for reaching the damping limit
People has good damping effect, is adapted to a variety of places such as Uneven road and scene carries out quickly rescue transport patient；II grade
Position is half opening state, has good damping effect to (temporarily setting 100 ㎏'s or so the) patient for heavier-weight of carrying a load on the back；III grade
Position is full opening state, and (temporarily set 50 ㎏s or so the) patient lighter to weight of carrying a load on the back has good damping effect, is adapted to
Quickly rescue, which is carried out, in a variety of places such as Uneven road and scene transports all kinds of patients.
Technical controlling principle: the general all conversions of shifting switch 45 (gear is standing gear) at II gear.When this is opened
When closing in II gear (feeling patient body weight in 100 ㎏ or so), the work from patient body weight and the self weight of emergency bed upper body part
It is acted directly on damper cylinder column 5 with gravity, after compressing damper cylinder column 5 carries out cushioning buffer effect in damping cylinder assembly 1, again
It is conducted back and forth in hydraulic oil pipe 4 by oppressing hydraulic oil, because the switch is in II gear, half opening state, active force is more smooth
Further buffering decompression is transmitted in the third level pressure-reducing cushioning device inside buffer pressure-reducing device 2 back and forth, to reach good
Good damping effect；When meeting patient body weight overweight (about 150 ㎏ --- 200 ㎏), shifting switch 45 is just transformed into I gear
Place, shifting switch 45 are increased to the resistance for passing through 4 hydraulic oil of hydraulic oil pipe, when the percent of pass and increase for reducing hydraulic oil pass through
Between, that is, limit and hydraulic oil is delayed to pass in and out buffer pressure-reducing device 2 back and forth, to achieve the effect that distinguish damping；As chance patient
Weight is more than that the layered structure limit or chance especial patient do not need damping, and shifting switch 45 is just transformed into 0 grade
At position, shifting switch 45 closes hydraulic oil pipe 4, and hydraulic oil can not circulate back and forth in hydraulic oil pipe 4, makes damper cylinder column 5
By the support of hydraulic oil in damping storehouse 11, can not be done in damping cylinder sleeve 12 and damping storehouse 11 it is up and down, can not be to buffering
Spring 8 and damping spring 15 implement contention effect, so that emergency bed be made to lose shock-absorbing function；When chance patient body weight relatively light (about 50
㎏ or so) when, shifting switch 45 is transformed at III gear, the circulation of hydraulic oil no longer in control hydraulic oil pipe 4, that is,
The limitation to disengaging 2 hydraulic oil of buffer pressure-reducing device is lost, is caused in the hydraulic oil and buffer pressure-reducing device 2 in damping storehouse 11
The complete connection of hydraulic oil, the third level pressure-reducing cushioning device being arranged inside buffer pressure-reducing device 2 are completely in pressure-reducing cushioning shape
State, so that emergency bed be made to achieve the effect that good damping.
4, the effect of hydraulic oil pipe 4 and technical controlling principle
The device is by more hydraulic oil pipes 4 and multiple hydraulic oil pipe joints (the first hydraulic oil pipe joint 14 and the second hydraulic oil
Pipe fitting 24) it constitutes.Hydraulic oil pipe 4 passes through the first hydraulic oil pipe joint 14 and the second hydraulic oil pipe joint 24 for damping cylinder assembly
1 damping storehouse 11 to the shifting switch 45 of shifting switch device 3 and the hydraulic oil effect storehouse 18 of buffer pressure-reducing device 2 is connected with each other
Get up, makes the acting gravity force being self-possessed from patient body weight and emergency bed upper body part when acting on damper cylinder column 5, because of pressure-reducing cushioning
Effect generates compression and reaction force, these active forces all need to pass to and pressure-bearing by the hydraulic oil pipe 4 full of hydraulic oil,
So that the device is realized a complete damping entirety, good damping effect is played to the carry a load on the back patient of transport of rescue carrigae.
5, the composition of damping spring 15 and relief spring 26, function and technical controlling principle
Damping spring 15 is made of weak property damping spring 16 and epistasis damping spring 17, and relief spring 26 is by weak property relief spring 27
It is formed with epistasis spring 28, this structure makes damping spring 15 and relief spring 26 have split reduction pooling feature.Depressurize bullet
Spring 26 by compression travel be less than damping spring 15 by compression travel, the mutual cooperation of two groups of springs just makes entire damping device
Form a set of perfect, firm pressure-reducing cushioning system.The part for receiving compression end of damping spring 15 and relief spring 26 is
The weaker weak property damping spring 16 and 27 of elasticity adds buffer spring 8, they can receive 50 after being combined with each other --- 100 ㎏ it
Inner body heavy patient is in pressure when rising and falling of jolting, that is, when patient body weight is more than after 100 ㎏, weak 16 He of property damping spring
27 pressure for just being jolted generation are compressed to the lowest limit in the moment jolted, then undertake damping, buffering by epistasis damping spring 17 and 28
Effect；The support section of damping spring 15 and relief spring 26 is the powerful epistasis damping spring 17 and 28 of elasticity, they are mutually
The active force that jolts when rising and falling in moment of patient that weight is 200 ㎏ is able to bear after combination, will not because jolt back and forth by
It is compressed to bottom.This construction namely ensures when implementing rescue transportational process to the patient that weight is 200 ㎏, because of emergency bed row
Walking road surface and excessively jolting causes to occur significantly to tremble, and this two groups of spring lost its bounces will not occurs, must play good
The effect of damping, buffering.
Technical controlling principle: this design ensures that medical staff is bad in road conditions with emergency bed transport different weight patient
Place in when quickly walking, though shifting switch 45 in I gear, II gear or III gear, in the setting damping limit
Never will appear excessively to jolt because of road surface causes damping spring 15 and relief spring 26 due to moment is compressed to bottom and follows the string
The significantly vibration generated, avoids the problem that causing secondary injury to patient.
Three, the working principle of a kind of damping device of emergency call salving bed
Occur the state of an illness need using emergency bed rescue transport patient when, medical staff first according to the weight regulation of patient convert
Shifting switch 45 is just transformed at II gear by shifting switch 45 when meeting patient body weight heavier (estimation is in 100 ㎏ or so)
(gear is standing gear), medical staff is using stretcher or assists on the big frame 49 of the upper main body that patient is placed on emergency bed, comes
From patient body weight and rescue big 49 part of frame of bed main body from the active force reformed, pass through upper bracket 57 and lifting connecting elements
56 are transmitted on damper cylinder column 5, and damper cylinder column 5 will be moved downward in damping cylinder sleeve 12 by the gravity contention effect.When
When damper cylinder column 5 is moved downward along damping cylinder sleeve 12, the buffer spring 8 of the part on damper cylinder column 5 is covered in shelves ear 7 and damping
Cylinder sleeve 12 stops to subject 5 downlink bring active force of damper cylinder column under limit, formed and execute first order damping, buffering machine
The receiving damper cylinder column 5 of structure does work when downward movement, it and second level damping, buffering mechanism and third level damping, buffering machine
Structure bears the pressure of 5 downlink of damper cylinder column jointly；The lower part that damper cylinder column 5 is inserted into inside damping cylinder sleeve 12 (it is close to be equipped with barrier
Three set of first excessive sealing ring 13 of sealing liquid pressure oil) bottom is installed in the weak property damping spring 16 full of hydraulic oildamping storehouse 11
15 support of damping spring formed with epistasis damping spring 17, when damper cylinder column 5, which is pressing against damping spring 15, to be moved downward, subtract
The weak property damping spring 16 of shake spring 15 first receives the compressing of 5 downstream pressure of damper cylinder column, after oppressing to a certain extent, epistasis
Damping spring 17 is also squeezed that (when active force is smaller, weak property damping spring 16 cooperates higher level and junior's pressure-reducing cushioning system
Play the role of good pressure-reducing cushioning, when active force is larger, weak property damping spring 16 is just directly forced into bottom sometimes, loses
Pressure-reducing cushioning ability, epistasis damping spring 17 takes over force fit higher level at this time and junior's pressure-reducing cushioning system plays well
Pressure-reducing cushioning effect), this structure of damping spring 15 subjects 5 downlink bring active force of damper cylinder column, is formed and is held
Work when the receiving damper cylinder column 5 of second level damping, buffering mechanism of going does downward movement, it and first order damping, buffering machine
The pressure of 5 downlink of damper cylinder column is born jointly by structure and third level damping, buffering mechanism；At this point, because of the construction reason in damping storehouse 11,
The downlink of damper cylinder column 5 generates contention effect power to hydraulic oil in damping storehouse 11, and hydraulic oil passes through in compression shock absorption storehouse 11 by force
Hydraulic oil is full of in first hydraulic oil pipe joint 14, hydraulic oil pipe 4() shifting switch 45(is flowed to because the switch is in II gear half
Opening state, can to hydraulic oil back and forth negotiability generate resistance, delay hydraulic oil back and forth through the time of shifting switch),
The hydraulic oil inside buffer pressure-reducing device 2 full of hydraulic oil is flowed by hydraulic oil pipe 4 and the second hydraulic oil pipe joint 24 again to make
With in storehouse 18；Because hydraulic oil acts on storehouse 18 itself design structure reason, which is oppressed by hydraulic oil and pushes decompression piston
19 tip portion (equipped with three sets of excessive sealing rings 21 of obstruction seals hydraulic oil) is taken exercises in piston/cylinder 20, is subtracted simultaneously
It presses the thick end portion of piston 19 also pressing against relief spring 26 in decompression storehouse 25 and does compressing movement；When 19 thick end portion of decompression piston
When pressing against the movement of relief spring 26, the weak property relief spring 27 of relief spring 26 first receives compressing, after compressing to a certain extent,
Epistasis relief spring 28 is also squeezed that (when active force is smaller, weak property relief spring 27 cooperates supervisory pressure-reducing cushioning system
Play the role of good pressure-reducing cushioning, when active force is larger, weak property relief spring 27 is just directly forced into bottom sometimes, loses
Pressure-reducing cushioning ability, epistasis relief spring 28 takes over the supervisory pressure-reducing cushioning system of force fit and plays good decompression at this time
Buffer function), at the same time, with movement of 19 thick end portion of decompression piston in decompression storehouse 25, make to depressurize space in storehouse 25
Become smaller rapidly therewith, air moves also with decompression piston 19 and is quickly discharged decompression storehouse 25 by mouth 30 of taking a breath, and enters
In the air inlet and exhaust valve storehouse 32 taken a breath in storehouse 31, under the effect of the pressure, open rapidly the air outlet valve 33(valve be encounter it is certain
Pressure can just be forced to open, so it also functions to certain buffering depressurization), into filtering cabin 36, pass through thin filter screen
39 and coarse filtration net 37 reach in disengaging gas storehouse 41, then be discharged in the external world by vertical air vent 42 and cross scavenging hole 43；Subtract
Pressing spring 26 and air outlet valve 33 etc. subject the downlink bring active force of damper cylinder column 5, are formed and execute third level damping
The receiving damper cylinder column 5 of buffer gear does work when downward movement, it and first order damping, buffering mechanism and second level damping
Buffer gear bears the pressure of 5 downlink of damper cylinder column jointly.Buffer spring 8, damping spring 15 and relief spring 26 exist like this
Shifting switch 45 is adjusted under shift control, is accepted together from the big frame 49 of rescue bed main body and patient body weight conduction and to weigh
The pressure of power.When the pressure causes the downlink of damper cylinder column 5 to reach certain limit, by the buffering elastic of first order damping, buffering mechanism
What the relief spring 26 of spring 8, the damping spring 15 of second level damping, buffering mechanism and third level damping, buffering mechanism collectively constituted
Damping device combines because of itself reaction force and continues traveling downwardly generation rebound resistance to damper cylinder column 5, and discharges jointly；
At this moment, the epistasis relief spring 28 of relief spring 26 and weak property relief spring 27 discharge rapidly bounce, head on decompression piston 19
Thick end portion carrier tip portion is taken exercises in piston/cylinder 20, at this point, decompression piston 19 oppresses hydraulic oil effect storehouse
18 hydraulic oil is open-minded because the switch is in II gear half by hydraulic oil pipe joint 24, the reflux of hydraulic oil pipe 4 shifting switch 45(
State, can to hydraulic oil, negotiability generates resistance back and forth, delay hydraulic oil back and forth through the time of shifting switch), then lead to
It crosses hydraulic oil pipe 4 and hydraulic oil pipe joint 14 enters in damping storehouse 11, at the same time, the epistasis damping spring 17 of damping spring 15
Bounce is discharged rapidly with weak property damping spring 16, acts on the active force on hydraulic oil with third level damping, buffering mechanism at this time
Ask damper cylinder column 5 along 12 uplink of damping cylinder sleeve jointly, at the same time, 8 lower end of buffer spring relies on damping cylinder sleeve 12 to shelves
Ear 7 discharges bounce, holds in the palm 5 uplink of damper cylinder column；At the same time, as 19 thick end portion of decompression piston is at piston/cylinder 20
The maximum rebound degree of relief spring 26 is moved and reached, space in storehouse 25 is depressurized and expands rapidly therewith, urgent need air supplement (
Happen suddenly in decompression storehouse 25 raw space become larger and under the action of generating powerful suction), at this moment, extraneous air is also with decompression piston
19 move and are quickly entered in filtering cabin 36 by the vertical air vent 42 and cross scavenging hole 43 of disengaging gas storehouse 41, by thick
The filtering of filter screen 37 and thin filter screen 39 enters back into air inlet and exhaust valve storehouse 32, and air, which opens rapidly the intake valve 35(valve, is also
Can just be forced to open encountering certain pressure, so it as air outlet valve 33, also functions to certain buffering depressurization) it is logical
It crosses ventilation mouth 30 to enter in decompression storehouse 25, the air lacked in decompression storehouse 25 is supplemented, that is, completes the extruding of a frequency
With rebound (pressure-reducing cushioning) working cycles；When the certain rebound dynamics of arrival is (according to patient body weight, implantation time and shifting switch
Depending on 45 gear, the gear of gear switch 45 is small, patient body is heavy, the implantation time is slow, rebound dynamics with regard to light, shifting switch 45
Gear is big, patient body's heavy and light, implantation time are fast, and rebound dynamics is just big, and the generation frequency of trembling is just more), just and start by gravity
Compressing 5 downlink of damper cylinder column is influenced, repeats the above extruding and rebound work, (this is also spring in damping, buffering side in cycles
Face has the characteristic of good action to determine), until the effect that the gravity when damping device of emergency bed is by patient's implantation generates
Power damping, buffering is exhausted, and just reaches an opposite stationary state.The emergency bed carrys a load on the back patient's walking in rough road
When face, and by the progress damping of above-mentioned damping, buffering principle and buffering, emergency bed is made to be in one rapidly relatively slightly
Degree state of trembling, avoid emergency bed suddenly put stretcher and walking more jolt place when, the secondary wound caused by urgent patient
Evil problem.
The lighter patient of weight (estimation is in 50 ㎏ or so) walking is carried a load on the back in roughness pavement using emergency bed when encountering
It is upper generation by a relatively large margin when jolting, shifting switch 45 is just transformed at III gear by medical staff, according to shifting switch device 3
Composition, function and technical controlling principle, shifting switch 4 no longer in hydraulic oil pipe 4 hydraulic oil circulation limit, damping storehouse
The hydraulic oil in hydraulic oil and buffer pressure-reducing device 2 in 11 is in complete connection state, at this moment, the first order, the second level and
Three-level pressure-reducing cushioning mechanism is completely in pressure-reducing cushioning state, and entire damping device is made to reach a good damping state, fast
The speed active force that trembles caused by jolting carries out neutralizing reduction, that is, protects patient, and accelerates the speed that transport is rescued to patient
Degree.When meeting patient body weight overweight (estimation in 150 ㎏ --- 200 ㎏ are not above the damping limit), just by 45 turns of shifting switch
It changes at I gear, shifting switch 45 is increased to the resistance for passing through 4 hydraulic oil of hydraulic oil pipe, reduces percent of pass and the increasing of hydraulic oil
Add and delay hydraulic oil to pass in and out buffer pressure-reducing device 2 back and forth by time, that is, limitation, to achieve the effect that distinguish damping.
It is more than that the layered structure limit or chance especial patient do not need to subtract when meeting patient body weight overweight (estimation is in 200 ㎏ or more)
Shake, just shifting switch 45 is transformed at 0 gear, shifting switch 45 closes hydraulic oil pipe 4, and hydraulic oil can not be hydraulic
It circulates back and forth in oil pipe 4, makes damper cylinder column 5 by the support of hydraulic oil in damping storehouse 11, it can not be in damping cylinder sleeve 12 and damping
It moves up and down in storehouse 11, contention effect can not be implemented to buffer spring 8 and damping spring 15, so that emergency bed be made to lose damping
