Abstract
The utility model relates to an integral medical electromagnetic brake device, which comprises an electromagnet. The integral medical electromagnetic brake device is characterized in that the electromagnet is connected with an armature via a fixing screw, a holding cavity is arranged in the electromagnet, and an adjusting component is disposed in the holding cavity. Besides, a work surface of the adjusting component is connected with the armature, and a brake component is disposed at a working end of the armature. Accordingly, locking and unlocking between a brake column and a brake surface can be realized on the premise of avoiding electromagnetic interference. In addition, an air sac device is omitted in the total process, and the shortcomings of gas leakage, cracks and noise can be avoided. The integral medical electromagnetic brake device can improve integral safety and accordingly is worthy of being popularized.
Description
Technical field
The utility model relates to a kind of braking device, relates in particular to the medical electromagnetic brake device of a kind of integral type.
Background technique
Medical braking mechanism is the important component part of medical hoist tower system, and it has improved the stability and the reliability of medical hoist tower greatly.Operator are free to control the motion of tower crane and stop.Most medical brake system that adopt are rubber pneumatic bag brakes in the present domestic medical industry; The working principle of this kind brake is; Air bag charges into to expand behind the gas and contacts with brake lining, reaches braking action (because he under inflated condition, brake, so we call the airbag aeration brake to it hereinafter) rubber pneumatic bag inflation and brakes owing to preparation process is simple thereby produce frictional force; Advantage such as with low cost obtains general application in industry.But medical tower crane most of the time in the process of using is (airbag aeration brake just is in inflated condition for a long time) that remains static.Rubber pneumatic bag progressively exposes many defectives (such as gas leakage, be full of cracks, noise etc.) and therefore, is unfavorable for promoting the use of in long-term continuous charge.
The model utility content
The purpose of the utility model is exactly the problems referred to above that exist in the existing technology in order to solve, and provides a kind of integral type medical electromagnetic brake device.
The purpose of the utility model realizes through following technological scheme:
The medical electromagnetic brake device of integral type; Include electromagnet; Wherein: described electromagnet connects armature through set screw, is provided with receiving cavity in the described electromagnet, is provided with adjusting part in the described receiving cavity; The working surface of said adjusting part links to each other with armature, and the working end of said armature is provided with brake assemblies.
Further, the medical electromagnetic brake device of above-mentioned integral type, wherein: described adjusting part includes adjusting screw, and described adjusting screw outer race is provided with elastic component.
Further, the medical electromagnetic brake device of above-mentioned integral type, wherein: described elastic component is a spring, or described elastic component is the stack shell fragment.
Further, the medical electromagnetic brake device of above-mentioned integral type, wherein: the operative end surface of said set screw is the plane.
Again further, the medical electromagnetic brake device of above-mentioned integral type, wherein: described brake assemblies includes braking column, and the operative end surface of said brake assemblies is distributed with friction plate.
The advantage of the utility model technological scheme is mainly reflected in: avoiding under the prerequisite of electromagnetic interference, can realize locking and releasing between braking column and the brake lining.And whole process need not the participation of air bag device, can avoid occurring the defective such as gas leakage, be full of cracks, noise.Thus, adopt the Security that can also improve integral body behind the utility model, be worthy to be popularized.
Description of drawings
The purpose of the utility model, advantage and characteristics will illustrate through the non-limitative illustration of following preferred embodiment and explain.These embodiments use the prominent example of the utility model technological scheme, and all technological schemes of taking to be equal to replacement or equivalent transformation and forming all drop within the scope of the utility model requirement protection.In the middle of these accompanying drawings,
Fig. 1 is the organigram of the medical electromagnetic brake device of integral type.

Embodiment
The medical electromagnetic brake device of integral type as shown in Figure 1 includes electromagnet 1, and its unusual part is: the electromagnet 1 that the utility model adopted connects armature 3 through set screw 2.Specifically, be provided with receiving cavity in the electromagnet 1, be provided with adjusting part in this receiving cavity.Simultaneously, the working surface of adjusting part links to each other with armature 3, and the working end of armature 3 is provided with brake assemblies.
With regard to the utility model one preferred implementation; Consider that the contact matching between follow-up brake assemblies and the brake lining 8 is obtained certain brake to be guaranteed; The adjusting part that the utility model adopted includes adjusting screw 4, and these adjusting screw 4 outer race are provided with elastic component.
Further, consider that elastic component carries out suitable qualification to the physical location of adjusting screw, the elastic component that the utility model adopted is a spring 5.Certainly, if adopt the stack shell fragment also can play similar effect.In order to let set screw 2 accurately limit the distance that combines between brake assemblies and the brake lining 8, the operative end surface of set screw 2 is the plane.
Again further, in order to promote the friction effect of brake, guarantee the normal operation of brake, the brake assemblies of employing includes braking column 6, and the operative end surface of this brake assemblies is distributed with friction plate 7.
In conjunction with the actual use condition of the utility model, armature 3 and electromagnet 1 are connected through adjusting screw, and the spring 5 of 1 of the compressible armature 3 of adjusting screw and electromagnet.Specifically, after electromagnet 1 was fixed, spring 5 produced armature 3 and upwards pressure, and this pressure is applied on the braking column 6, made the friction plate 7 of braking column 6 and 8 of brake linings produce frictional force, played braking action.Afterwards, can attract armature 3, produce downward power and work as when electromagnet 1 energising produces magnetic force.When this power was enough big, making the braking column 6 and the pressure of brake lining 8 was zero, and brake is removed.
Can find out through above-mentioned character express, behind employing the utility model, avoid under the prerequisite of electromagnetic interference, can realize locking and releasing between braking column and the brake lining.And whole process need not the participation of air bag device, can avoid occurring the defective such as gas leakage, be full of cracks, noise.Thus, adopt the Security that can also improve integral body behind the utility model, be worthy to be popularized.
