Abstract
The invention provides a gas cut-off brake device applied to a medical tower crane. The gas cut-off brake device applied to the medical tower crane comprises a brake damper, a brake axle, a cylinder piston, a cylinder body, a set of dish-shaped washers and a spring washer cover. The spring washer cover which is provided with the dish-shaped washers is placed in a cylinder, the brake damper is inlaid into a groove in the front end of the brake axle in a pressing mode, the rear end of the brake axle and the front end of the cylinder piston are screwed through threads, a brake cylinder and the dish-shaped washers form the power part of braking, the dish-shaped washers push the cylinder piston to provide sufficient friction force for braking, the tower crane is positioned at the needed position, after gas is supplied to the inside of the cylinder, the brake axle retracts after the piston compresses the dish-shaped washers, the brake damper is disengaged from a braked piece to remove braking, after a gas source is cut off, the dish-shaped washers restore the original shape, and a braking state is achieved again. According to the gas cut-off brake device applied to the medical tower crane, gas cut-off braking is used, the defect of braking failure due to gas cut-off is overcome, energy saving and environmental protection are achieved, and the pollution of noise, electromagnetic waves, waste gas and the like is avoided.
Description
One, affiliated technical field
The present invention relates to a kind of braking device that is applied to medical hoist tower, relate in particular to a kind of device of break brake.
Two, technical background
Medical hoist tower is the medical equipment that are widely used at present modernization operating room, is holding various Medical Instruments and medical instrument on medical hoist tower, thus the smooth running of tower crane and flexibly brake be very important.In Hospitals at Present, conventional tower crane adopts mechanical brake more, and mechanical brake is complex operation not only, and noise is large, and occurs brake failure sometimes.Even comparatively advanced aerodynamic brake is also to adopt to pneumatic brake at present, be to the defect of pneumatic brake maximum: when dying suddenly or there will be brake failure and brake drift during for unsaturated vapor, slightly thrust just there will be mobile and rocks, and the equipment being much placed on tower crane does not allow to rock, therefore exist very large potential safety hazard in operation.
Three, summary of the invention
The present invention is directed to above technical problem, a kind of break brake device is provided, make tower crane can stop, come to a complete stop in any working position, be not subject to extraneous interference and move, for the medical equipment on tower crane and instrument provide a relative static stabilized platform.
Described break brake device is comprised of following six parts: 1 brake damping, 2 brake axles, 3 cylinder pistons, 4 cylinder blocks, 5 one groups of saucer washers, 6 play cushion covers.
Between its brake axle rear end of described braking device and cylinder piston front end, adopt and be threaded, make the stability of brake axle stronger, oscillating quantity during brake is less, and during maintenance, dismounting is more convenient.
Brake damping embeds by extruding in the groove of brake axle front end and is connected with brake axle, and scribbles tackiness agent at the surface of contact of brake axle groove and the damping of braking.Extruding embeds and connects and bonding common use, has increased serviceability and the Security of brake.
Several saucer washers are stacked and become one group, be positioned over and play in cushion cover, the Main Function that plays cushion cover is the sphere of activities of restriction saucer washer.
The cylinder of described braking device is thin cylinder, and volume is little, and quality is light.And cylinder piston rear end is fluted, when saucer washer deforms, for playing cushion cover embedding piston rear end, provide appropriate space.In addition, on cylinder, be also designed with inlet hole and air outlet hole.
The present invention acts on a kind of tower crane that comprises this break brake device.Compare with existing service brake, advantage is:
Compare with pure mechanical brake, the present invention is integrated in saucer washer in brake cylinder cylinder body dexterously, has reduced the volume of a whole set of brake.Can also according to circumstances select the number of saucer washer to regulate the pressure of brake, solve the problem that conventional machinery brake pressure can not regulate.The present invention adopts to gas and removes brake, removes brake easier than pure machinery, operates more convenient, more stable, and noise is less, and reliability is also higher.
With to pneumatic brake, compare, the present invention adopts break brake, has effectively avoided under emergency case, because dying, causing brake failure or the vibrations that bring because source of the gas is unstable and impact, thereby can protect better the smooth running of medical equipment on tower crane.
Compare with electromagnetic brake, the present invention has avoided causing because of power-off suddenly the defect of brake failure, and the present invention adopts saucer washer to provide precompression to reach the object of brake to tower crane, so not only product self can, by electromagnetic interference, not disturb other Medical Instruments nor can generate electromagnetic waves.
Environmental protection of the present invention, energy-conservation, can not produce the pollutions such as noise, electromagnetic wave, waste gas in using process, and using electricity wisely and use gas effectively.
Four, accompanying drawing explanation
Fig. 1 is the generalized section of structure of the present invention, and is now braking state.
Fig. 2 is the state of brake of removing after inflation in cylinder.
Five, embodiment
As shown in Figure 1, the present invention is a kind of break brake that is applied to medical hoist tower, mainly comprises six parts: the damping of 1. braking, 2. brake axle, 3. cylinder piston, 4. cylinder block, 5. saucer washer, 6. play cushion cover.
The present invention is easy to assembly, first that several saucer washer concave surfaces are relative with concave surface, and stack relative with convex surface of convex surface forms one group, then they is put into and plays cushion cover, more vertically put in the cylinder block of brake playing cushion cover.In addition, brake damping is pressed in the groove that embeds brake axle front end, then the front end of brake axle rear end and cylinder piston is screwed by screw thread.Finally cylinder piston is put into cylinder block, pressing saucer washer.Attention, according to the cylinder degree of depth, suitably regulates the number of saucer washer.
Brake damping and brake axle have formed the agency part of brake, by braking damping and played the object of brake by the friction between brake member.Brake cylinder and saucer washer have formed the power section of brake, and saucer washer promotes cylinder piston for brake provides enough frictional force, tower crane is positioned at firmly to the position needing, and wherein Fig. 1 is braking state.By the inlet hole on cylinder to gas after, the cylinder piston of brake cylinder compression saucer washer makes it produce elastic strain, and pulls brake axle, the damping that makes to brake departs from by brake member, thereby removes brake, state when wherein Fig. 2 brakes for removing.When tower crane is moved to Xin position, cut off source of the gas, saucer washer restores to the original state rapidly, again enters braking state.
Installation method of the present invention is simple, only need select suitable bolt to it, to install fixing by mounting hole.Thereby improved versatility of the present invention, increased its Applicable scope, except medical hoist tower, can also be applied on the similar equipment such as Medical stand.
