Description
Technical field
The present invention relates to a kind of plumbous Weight control mechanism of obeying.
Background technology
In Hospital Authority, doctors have many medical operatings need operate under X-ray, especially in recent years, adopt Wicresoft's interventional therapy to replace the application of diseases such as traditional surgery treatment heart disease, cerebrovascular, gallbladder more and more, because this operation is to carry out under the supervision of X-ray, for preventing that damaging doctors must wear the bigger lead clothes of weight when operating, to reduce X-ray to the radiation of human body.Because plumbous clothes radioprotective effect is relevant with lead tolerance, and lead tolerance is relevant with weight, so general lead clothes are all very heavy.Doctors not only will bear the pressure that operation brings, and also will bear the gravity that the plumbous clothes of long-time dress bring, and doctors tire out, and if things go on like this also can cause some chronic strains to human body.In order to address this problem, there is the people once to propose some designs, be that the technical scheme that 03215638.3 utility model patent proposes is at ceiling a hanging ring to be set as the patent No., plumbous clothes are hung on the hanging ring by pulley.This design has seriously limited doctor's activity space.The patent No. is that 201020109418.3 utility model patent then is provided with a plumbous cover and walker, and the doctor operates by being located at plumbous cover upper observation hole and hole.This device is too simple, in use can run into many inconvenience.The patent No. can not adapt to doctor's dynamic change in operation for 200920091668.6 utility model provides a kind of fixed suspended structure.The common deficiency of above-mentioned prior art all is to have laid particular stress on static loss of weight, and the dynamic loss of weight demand in operating for doctors is inconsiderate.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of plumbous Weight control mechanism of obeying, not only can help the doctor to share most weight of plumbous clothes by this device, and when position changes in doctor's operation, also can follow the tracks of tension variations and make corresponding adjustment, thereby keep constant subtracting to release weight.
Technical scheme of the present invention is: the top of main body frame is cantilever beam, and the head end of cantilever beam is provided with hanging ring, and tail end is connected with lifting shaft is vertical.Be column below lifting shaft, at column linear module be housed; Bearing bracket stand and linear bearing are equipped with in the top of linear module; The bottom of lifting shaft is contained in the linear bearing, is slidingly matched with linear module, and the bottom of lifting shaft is connected with slide bar in the linear module, and the bottom of slide bar is installed on the slider block in the linear module.The bottom of linear module connects with motor by shaft coupling.Motor drives slide bar and the linear lifting of lifting shaft by leading screw.The lower end of control line is fixed on the bottom of linear module, and the upper end is enclosed within on the hanging ring of cantilever beam head end.The bottom of column is fixed on the end face center of the inboard frame of semi-circular base, and universal wheel is equipped with in the below of base.
Weight measurement mechanism comprises buffering extension spring and pulling force sensor, and fasten on control line the upper end of buffering extension spring, and pulling force sensor is suspended on the bottom of buffering extension spring, and plumbous clothes hanged hook is contained in the bottom of pulling force sensor.
Weight control mechanism comprises the telemetry circuit plate that is connected with motor, and this telemetry circuit plate can be made by 51 series monolithics.In the telemetry circuit plate, be provided with and pulling force sensor between signal receiving element, motor rotating switching device and and motor between the signal output element.
Advantage of the present invention is: structure is simple and direct, easy to operate, the semi-circular base that universal wheel is housed provides convenience for doctor's walking, the weight TT﹠C system not only can help the doctor to share plumbous most of weight of obeying, and it is constant also to follow the tracks of tension variations maintenance pulling force when the position variation takes place the doctor in operation.

The specific embodiment
Example 1
As shown in Figure 1, the present invention is made up of main body frame, weight measurement mechanism and Weight control mechanism.
The top of main body frame is cantilever beam 1, and the head end of cantilever beam 1 is provided with hanging ring, tail end and 4 vertical connections of lifting shaft.Be column 17 below lifting shaft 4, at column 17 linear module 11 be housed; Bearing bracket stand 6 and linear bearing 7 are equipped with in the top of linear module 11; The bottom of lifting shaft 4 is contained in the linear bearing 7, is slidingly matched with linear module 11, and the bottom of lifting shaft 4 is connected with slide bar 9 in the linear module 11, and the bottom of slide bar 9 is installed on the slider block 10 in the linear module 11.The bottom of linear module 11 connects with motor 13 by shaft coupling 12.Motor 13 drives slide bar 9 and lifting shaft 4 linear liftings by leading screw.The lower end of control line 8 is fixed on the bottom of linear module 11, and the upper end is enclosed within on the hanging ring of cantilever beam 1 head end.The bottom of column 17 is fixed on the end face center of semi-circular base 16 inboard frames, and universal wheel 15 is equipped with in the below of base 16.
Weight measurement mechanism comprises buffering extension spring 2 and pulling force sensor 3, and fasten on control line 8 upper end of buffering extension spring 2, and pulling force sensor 3 is suspended on the bottom of buffering extension spring 2, and plumbous clothes hanged hook 5 is contained in the bottom of pulling force sensor 3.
Weight control mechanism comprises the telemetry circuit plate 14 that is connected with motor 13, and this telemetry circuit plate 14 is made by 51 series monolithics.In telemetry circuit plate 14, be provided with and pulling force sensor 3 between signal receiving element, motor 13 rotating switching devices and and motor 13 between the signal output element.
Example 2
This example is operation principle of the present invention.
Weight TT﹠C system of the present invention is actually the constant hunting gear of a kind of pulling force, and this device is about the weight of plumbous clothes 5 to the setting pulling force of lead clothes 5, and in order to keep this pulling force constant, the height of slide bar 9 obviously should be fixed.To follow doctor's work position to occur upper and lower when mobile when lead clothes 5, and the height of slide bar 9 also should be changed thereupon, otherwise this device is obeyed 5 pulling force to lead will disequilibrium.This moment pulling force sensor 3 and telemetry circuit plate 14 effect just be to design slide bar 9 for cooperate doctor's position change rising or the falling head that should make.
Operation principle of the present invention is: the weight value of electrical signals that will promote protective garment 5 is set at W1, and plumbous clothing deadweight is W, and plumbous clothing is F to operator's pressure, then F=W-W1.W1 value wherein flows to telemetry circuit plate 15 by pulling force sensor 3 per 2 seconds circulation primary.
F is set at 100g～500g, and as 100＜F＜500g, motor stops operating, and plumbous clothing constant height is worked as F〉500g, motor just changes, and promotes plumbous clothing; As F＜100g, the motor counter-rotating reduces plumbous clothing.
