Description of drawings
Fig. 1 is the electric control schematic diagram of the stretcher lifting bed that provides among the embodiment;
Fig. 2 is the stretcher lifting bed pie graph that provides among the embodiment.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, this utility model embodiment is described in further detail below in conjunction with accompanying drawing.
Present embodiment provides a kind of stretcher lifting bed, mainly is made of three parts: base, elevating mechanism, and carriage; Connect by linkage between the base and bracket, as can adopting three connecting rods, four connecting rods etc.,
One, base
Base is the basic supporting construction of stretcher lifting bed, and as the base of whole stretcher lifting bed, in the present embodiment, the base of stretcher lifting bed is propping up of steel construction and is configured to, and is firm reliable;
Two, elevating mechanism
Elevating mechanism is used for comprising as the parts of realizing stretcher lifting bed elevating function, lifting actuator, and damping device,
Lifting actuator is by electric-controlled switch, compressor unit, and cylinder unit and gear unit constitute, and gear unit is made of former moving bar and follower lever, and former moving bar and compressor unit link, and follower lever and carriage link,
Whole elevating mechanism has electric and mechanical dual control, utilizes electronic installation control electromagnetism-gas-driving valve, electromagnetism-gas-driving valve control compressor unit, and as shown in Figure 1, lifting actuator lifting control is controlled by 3 electric-controlled switchs,
-electric-controlled switch S1:
Electric-controlled switch S1 control lifting actuator integral elevating, afterwards can make the stretcher integral elevating on the carriage, switch S 1 is connected air-operated solenoid valve, utilize the pressure of air driven pump to control rising and the decline of carriage in Z axle (perpendicular to the horizontal plane direction) position, and after hands leaves gauge tap, keep standing state.
Electric-controlled switch S2 and S3 are the controls of the local lifting of stretcher on the control carriage, according to the cause of disease difference of first-aid patients, and rescue personnel's different demands, the rising and the decline of control stretcher head part and tail part.
-electric-controlled switch S2:
The rising and the decline of electric-controlled switch S2 control stretcher lifting head of a bed part, when pressing the lifting key of electric-controlled switch S2, the indication of rising green light is bright, and the stretcher headstock partly rises, when arriving assigned address, release button, rising stops.Pressing stays falls key, and stretcher is got back to the home position.
-electric-controlled switch S3:
The rising and the decline of electric-controlled switch S3 control stretcher lifting tailstock portion, his operation principle is the same with switch S 2 with electric-controlled switch S1, also is on-off control air-operated solenoid valve brake actuator.
Below, be example with the lifting of stretcher lifting head of a bed portion, introduce the mechanical control procedure of stretcher lifting bed, as shown in Figure 2,1. be stretcher lifting head of a bed portion, by the 2. lifting of electric-controlled switch control gas compressor.2. gas compressor connects the actuating device of gas compressor, 3. promotes the flexible drive follower lever rise and fall 5. 4. of former moving bar by cylinder, realizes the lifting of stretcher afterbody.
In addition, elevating mechanism also is equipped with pneumatic damping device, stablizes means for adjusting limit of movement and handle etc.;
Pneumatic damping device
Pneumatic dampers is an independently pneumatic means, be connected on the follower lever, the power of utilizing air spring changes along with movement velocity and variation characteristic designs, when the application point motion of the power of guiding air spring than period faster spring resistance just obviously increase, when the application point motion is very slow, resistance does not then have, and realizes postponing and alleviating the purpose of big displacement of moment.
In order to reduce the jolt influence of external environment to stretcher, additionally added a pneumatic damping device 6. at the left front and right back of stretcher lifting bed, make the vibrations of stretcher lifting bed drop to minimum.Such design has avoided road conditions poor significantly, brings to a halt, the influence of unsafe condition to first-aid patients in the compartment such as turn round greatly.
Stablize means for adjusting limit of movement
The maintenance level stopping means in addition that links to each other with follower lever is regulated bottom maintenance level, and restriction follower lever rise and fall height, finely tunes the level height of medical bedstead, plays the adjusting protective effect.
The move left and right handle
7. base is fixed in the ambulance compartment by four pedestals, in order to allow the design hommization more of stretcher lifting bed, allow space in the convenient use medical chamber of medical personnel, base portion has also designed at headstock and the tailstock can allow the function of stretcher left and right sides translation on X-direction.
Stretcher respectively has a mechanical handle at headstock and tailstock bottom, two mechanical handle link to each other with power transmission shaft with connecting rod, when pressing mechanical handle, can make medical bedstead above the horizontal X axle to the left and right each 300mm be parallel to ground and move, this design makes in the narrow and small relatively free space of medical chamber, guarantee to give medical first aid personnel maximum and utilize armarium easily under the situation of sufferer personal security, rescue first-aid patients good condition is provided.
Three, carriage
Carriage is used to carry stretcher as the gripper shoe of stretcher lifting bed, can adopt steel plate, opens the holddown groove or the hole of docking with stretcher thereon, with convenient fixedly stretcher.
Medical aid personnel convenient when stepping on car and to rescuing personnel's safeguard protection for convenience, the increase of stretcher lifting bed has designed can extend the stretcher carriage the outer function of bed.
By the carriage handle operation that links to each other with connecting shaft, utilize pneumatic spring that whole movable carriage is risen, break away from fixture, driving the stretcher carriage stretches out outside the compartment, when the bottom support frame tilts to skid off about 15 degree outside the compartment 1 meter in the compartment, stretcher lifting bed top braces parts (draw-in groove and pulley) are connected with the bed bottom, are fixed by crossbeam.
Stretcher lifting bed in this utility model, have advantages such as simple to operation, portable and smart, utilize the automatic displacement of electric braking, base plate can prolong outside the car body, being beneficial to the first-aid personnel stablizes stretcher and moves, but the stretcher transhipment wounded up and down during ambulance one-man operation's stretcher realize that high low level changes automatically, provide advantage for conveniently rescuing and transferring the wounded rapidly.
The above only is preferred embodiment of the present utility model, and is in order to restriction this utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
