The medical treatment crane tower main body rotating device comprises a fixed outer sleeve and a rotating main shaft which is rotatably installed inside the fixed outer sleeve in sleeved mode, a flange plate is formed at the upper end of the fixed outer sleeve, and a bearing is installed between the inner wall of the fixed outer sleeve and the outer wall of the rotating main shaft. The lower end of the rotating main shaft is fixedly connected with a cross arm, and the rotating main shaft is provided with a brake device. According to the medical treatment crane tower main body rotating device, the rotating main shaft is provided with the brake device, so that the rotating main shaft can be rotated and positioned according to requirements, fixed positioning of an equipment box connected with the cross arm is ensured, convenience is brought to operation, and quality of the medical treatment crane tower main body rotating device is greatly improved.
Description
Technical field
The utility model relates to the medical equipment technical field, particularly a kind of medical tower crane main body rotating device with electromagnetic brake.
Background technique
The medical treatment tower crane is comparatively common medical equipment, and generally by main body rotating device, transverse arm and equipment box form, and wherein, main body rotating device is fixedly connected on transverse arm one end, and equipment box then is fixedly connected under the other end.Main body rotating device is used for medical tower crane is fixed in the roof, but and Arbitrary Rotation, make things convenient for the position of equipment box to be moved.The main body rotating device of existing medical tower crane all is not provided with braking device, and namely the equipment box position can not well be fixed, some the time bring inconvenience to operation, therefore be necessary existing the setting carried out architecture advances.
The model utility content
The purpose of this utility model is for the defective of prior art and deficiency, provides a kind of simple and compact for structure, the medical tower crane main body rotating device with electromagnetic brake that can be standing in arbitrary position.
For achieving the above object, the utility model is by the following technical solutions:
A kind of medical tower crane main body rotating device with electromagnetic brake described in the utility model, comprise fixed jacket and the rotatable rotary main shaft that is sheathed in the fixed jacket, described fixed jacket upper end forms flange plate, be provided with bearing between described fixed jacket inwall and the rotary main shaft outer wall, described rotary main shaft lower end is fixedly connected with transverse arm, and described rotary main shaft is provided with braking device.
Wherein, described braking device comprises transformer and supports the electromagnetic chuck be located at the rotary main shaft upper-end surface, and described transformer is electrically connected with electromagnetic chuck by wire.
Further, described rotary main shaft upper-end surface is provided with retainer ring, and described electromagnetic chuck supports and is located on the retainer ring.
Further, described bearing comprises two needle bearings and a thrust ball bearing, and described two needle bearings are and are symmetrically set in up and down between rotary main shaft and the fixed jacket, and described thrust ball bearing is located on the needle bearing of top.
The utility model beneficial effect is: the utility model is provided with braking device at described rotary main shaft, can be rotated the location to rotary main shaft as required, guarantee the equipment box stationary positioned that is connected with transverse arm, easy-to-operat has greatly improved the utility model quality.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present utility model.
Among the figure:
1, transformer; 2, electromagnetic chuck; 3, retainer ring; 4, fixed jacket;
5, rotary main shaft; 6, flange plate; 7, thrust ball bearing; 8, needle bearing;
9, transverse arm.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of medical tower crane main body rotating device with electromagnetic brake described in the utility model comprises fixed jacket 4 and the rotatable rotary main shaft 5 that is sheathed in the fixed jacket 4, braking device, and above-mentioned several parts consist of the utility model agent structure.
Described rotary main shaft 5 lower ends are fixedly connected with transverse arm 9, and transverse arm 9 is used for the connection device case.
Described fixed jacket 4 upper ends form flange plate 6, are used for the utility model is fixedly connected on the roof.
Be provided with bearing between described fixed jacket 4 inwalls and rotary main shaft 5 outer walls, what be convenient to rotary main shaft 5 and fixed jacket 4 is relative rotation.Particularly, described bearing comprises two needle bearings 8 and a thrust ball bearing 7, and described two needle bearings 8 are and are symmetrically set in up and down between rotary main shaft 5 and the fixed jacket 4, and described thrust ball bearing 7 is located on the needle bearing 8 of top.So arrange, the spin friction power between rotary main shaft 5 and the fixed jacket 4 is little.
Described rotary main shaft 5 upper-end surfaces are provided with retainer ring 3, and rotary main shaft 5 is provided with braking device, and described braking device comprises transformer 1 and to the electromagnetic chuck 2 of being located on the retainer ring 3, described transformer 1 is electrically connected with electromagnetic chuck 2 by wire.When rotary main shaft 5 with equipment box rotation when operating desired location, power supply passes into electromagnetic chuck 2 after transformer 1 transformation, electromagnetic chuck 2 produces magnetic fields, inhales mutually with rotary main shaft 5 upper-end surfaces, thereby makes rotary main shaft 5 fixing, equipment box can be realized positioning action.When adjusting the equipment box position such as need, electromagnetic chuck 2 outages, magnetic field disappears, and rotary main shaft 5 can rotate freely, to adjust as required the position of equipment box.
The advantages such as the utility model is mainly realized brake by electromagnetic field, has safety coefficient high, and easy to maintenance and noise is little.
The above only is better embodiment of the present utility model, therefore all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
