Description
Technical field
The present invention relates to a kind of feedback device of operating-table horizontal reset, especially relate to a kind of linear amplification formula intelligence operating-table horizontal reset feedback device.
Background technology
For adapting to the needs of operation, patient must be in different operation positions when operation.Because patient has been implemented anesthesia, all or part of meeting of patient body is lost consciousness, and is of flaccid muscles when operation, and guarding reflex effect major part disappears or weakens, and loses autonomous regulating power basically.So unsuitable operation position can increase patient's misery, postpone rehabilitation, even cause irremediable consequence.Therefore, suitable operation position is crucial to patient's operation safe, operation, yet these different operation positions all regulate obtaining through horizontal level.Like this, the importance of horizontal level is very outstanding.Obtain horizontal level, intelligent operating-table just need possess a cover to be measured and the device of controlling horizontal level, and its core is a feedback device.At present, similarly feedback device all is an equal proportion, does not have enlarging function, and its precision and sensitivity are limited, are difficult to reach higher requirement.
Summary of the invention
Technical problem to be solved by this invention provides a kind of linear amplification formula intelligence operating-table horizontal reset feedback device that enlarging function and its precision and sensitivity can significantly improve that has.
The present invention solves the technical scheme that its technical problem takes: a kind of linear amplification formula intelligence operating-table horizontal reset feedback device; Comprise the large pulley that is installed on the backboard and be installed on the truckle on the seat board wall; Described large pulley and truckle are in transmission connection; The middle part of truckle is provided with the turning cylinder of pick off, and truckle is fixedly connected with the turning cylinder of pick off.
Consider cost and economical and practical this on the one hand, described large pulley and truckle are in transmission connection employing is that large pulley passes through sense line and is connected with the outer ring of truckle.
For in operation, can effectively amplify feedack, the radius ratio of described large pulley and truckle is greater than 1, and further scheme is: the radius ratio of described large pulley and truckle is 2.
For ease being connected of the turning cylinder of truckle and pick off, be provided with pick off turning cylinder support between the turning cylinder of described truckle and pick off.
For when resetting, the truckle initial position of can transferring from a team to another automatically, the outside of described pick off turning cylinder support is provided with torque spring.
The invention has the beneficial effects as follows: can measure the position of backboard rapidly and exactly, giving function that pick off and processing center, apparatus of the present invention have amplification and its precision and sensitivity with information feedback can be the several times of common feedback device.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the cutaway view of the A-A face of Fig. 1;
Fig. 3 is a perspective view of the present invention.
1. sense lines among the figure, 2. large pulley, 3. jump ring, 4. truckle, 5. support,
6. pick off turning cylinder support, 7. pick off turning cylinder, 8. addendum cone screw, 9. torque spring.
The specific embodiment
Like Fig. 1, Fig. 2 and a kind of linear amplification formula intelligence operating-table horizontal reset feedback device shown in Figure 3; Comprise the large pulley 2 that is installed on the backboard and be installed on the truckle 4 on the seat board wall; Described large pulley 2 is in transmission connection with truckle 4; The middle part of truckle 4 is provided with the turning cylinder 7 of pick off, and truckle 4 is fixedly connected with the turning cylinder 7 of pick off; Described large pulley 2 and truckle 4 are in transmission connection, and what adopt is that large pulley 2 is connected through the outer ring of sense line 1 with truckle 4. The radius ratio of described large pulley 2 and truckle 4 is greater than 1, and further described large pulley 2 is 2 with the radius ratio of truckle 4; Be provided with pick off turning cylinder support 6 between the turning cylinder 7 of described truckle 4 and pick off, and the turning cylinder 7 of pick off and pick off turning cylinder support 6 are fixedly connected through addendum cone screw 8; The outside of described pick off turning cylinder support 6 is provided with torque spring 9, can automatically reset; Truckle 4 is fixedly connected with the seat board wall through support 5; Truckle 4 is fixed on the pick off turning cylinder support 6 through jump ring 3, in order that truckle 4 is not slided on axle.
In the amplification effect of needs change feedback device, only need to change the big perhaps smaller large pulley 2 of radius and get final product; Or the large pulley 4 that a plurality of radii size differ is installed on backboard, when changing amplification effect, only need changed to sense line 1 on the bigger or less large pulley 2 and get final product.The present invention feeds back the multiple that amplification multiple is large pulley 2 and truckle 4 radius ratios.Large pulley 2 is in transmission connection with truckle 4, not only can adopt sense line 1, also can adopt other connected modes such as belt chain.
When the backboard of intelligent operating-table turns an angle; Large pulley 2 is delivered to the truckle 4 on the seat board arm through sense line 1 with angle displacement; The turning cylinder 7 that truckle 4 drives pick off rotates together and gives pick off with this information feedback, and pick off further sends to feedback information the miniature processing center of intelligent operating-table, and processing center accurately calculates the difference between backboard present position and this position and the horizontal level according to feedback information; And then send the instruction make intelligent operating-table carry out desired action; Motion-feedback-motion, through continuous circulation, intelligent operating-table returns to horizontal level.
Motion conditions when the radius of large pulley 2 is truckle 4 twices is following:
When intelligent operating-table backboard upwards rotates 30 when spending, large pulley 2 turns over 30 degree simultaneously, because its radius is 2 times of truckle 4, so the turning cylinder 7 that truckle 4 drives pick offs turns over 60 degree together and gives pick off and processing center with this information feedback.Processing center can be sent instruction according to this information: intelligent operating-table backboard hydraulic cylinder action, and backboard is spent to obtain horizontal level to counter-rotation 30, promptly realize the horizontal reset of intelligent operating-table.
