Abstract
The utility model relates to a brake for a medical head mast revolving arm. The utility model comprises a revolving arm sleeve, a hollow revolving arm which is arranged inside the revolving arm sleeve and can rotate freely inside the revolving arm sleeve, and in addition a brake disk arranged on the head face of the hollow revolving arm sleeve, an air pressure profile ring arranged at the outer circle of the brake disk, and a control device to control the gas source and the pressure of the profile ring; the brake disk is coaxially fixed with the hollow revolving arm, with the external end disposed at the mouth of the revolving arm sleeve; the air pressure profile ring is fixed at the edge of the brake disk and is connected with the control device through a wind pipe. The utility model can ensure firm and stable connection of the hollow revolving arm and the revolving arm sleeve and ensures that the workbench does not offset.
Description
Technical field
The utility model relates to a kind of braking device of revoliving arm, relates in particular to the pneumatic spacing braking device of medical hoist tower revolving arm.
Background technique
Medical surgery room tower crane bottom is provided with worktable, prevents some operating theater instruments, instrument and apparatus etc.In actual use, worktable needs to rotate, and there is the low problem of revolution control degree in general similar swirl gear when revolution, promptly in the stop place instability, have thrust promptly can move, rock slightly.And in the operation on the worktable some article can not rock, therefore such swirl gear brings very big inconvenience for the operation technique person, simultaneously, also has some potential safety hazards.
The model utility content
The utility model provides a kind of medical hoist tower revolving arm that can make to turn to when requiring the position at above technical problem, transfixion, thus guarantee the braking device of the medical hoist tower revolving arm that worktable is stable.
The technical solution of the utility model is: comprise the pivoted arm cover and be arranged on hollow pivoted arm free to rotate in the pivoted arm cover, it also comprises the brake disc that is arranged on the hollow pivoted arm end face, the air pressure expansion loop that is arranged on the brake disc outer ring and source of the gas, expansion loop Pneumatic controller; Brake disc is coaxial with hollow pivoted arm and fixedly connected, and its outer end is positioned at pivoted arm cover running-on; The air pressure expansion loop is fixedly connected on brake disc dish edge surface; The air pressure expansion loop links to each other by tracheae with source of the gas, Pneumatic controller.
Be provided with a circle groove on brake disc dish edge, the air pressure expansion loop is located in the groove.
The corresponding air pressure expansion loop of described pivoted arm cover inwall position is provided with rubbing surface.
The utility model is provided with a brake disc by pneumatic control in the upper end of hollow pivoted arm, when pivoted arm turns to set angle, the operation Pneumatic controller, the air pressure expansion loop expands, expansion loop cylindrical after the expansion contacts with pivoted arm cover inwall, roof pressure pivoted arm cover inwall produces bigger frictional force, makes pivoted arm cover and hollow pivoted arm position relative fixed.The utility model can guarantee that hollow pivoted arm and pivoted arm cover can held stationary, guarantees that worktable is not offset.
Description of drawings

Fig. 2 is an A-A view among Fig. 1
7 is rubbing surfaces of pivoted arm cover inwall among the figure, the 8th, and source of the gas mouth, the 9th, air pressure control mouth.
Embodiment
As Fig. 1,2, the utility model comprises pivoted arm cover 3 and is arranged on hollow pivoted arm 1 free to rotate in the pivoted arm cover 3 that it also comprises the Pneumatic controller of the brake disc 5 that is arranged on hollow pivoted arm 1 end face, the air pressure expansion loop 4 that is arranged on brake disc 5 outer rings and source of the gas, expansion loop 4; Brake disc 5 is coaxial with hollow pivoted arm 1, and fixedly connected by attachment screw 6, its outer end is positioned at pivoted arm and overlaps 3 running-ons; Air pressure expansion loop 4 is fixedly connected on brake disc 5 dish edge surfaces; Air pressure expansion loop 4 links to each other by tracheae with source of the gas, Pneumatic controller.
Be provided with a circle groove 2 on brake disc 5 dish edge, air pressure expansion loop 4 is located in the groove 2.
Pivoted arm overlaps the corresponding air pressure expansion loop of 3 inwalls 4 positions and is provided with rubbing surface 7.
Working principle of the present utility model is: the utilization tracheae connects source of the gas mouth 8 with source of the gas and charges into pressurized air and make characteristic that expansion loop 4 expands and realize controlling with air pressure control mouthful 9 Pneumatic controllers that are communicated with.Expansion loop 4 is in inflated condition under the normal state, produces resistance to motion between brake disc 5 and pivoted arm cover 3, makes hollow pivoted arm 1 be in stationary state.Press the selector valve button of Pneumatic controller, expansion loop 4 communicates with atmosphere, expansion loop 4 releases, and expansion loop 4 is in contraction state, and the resistance that results from brake disc 5 disappears, but hollow pivoted arm 1 is in the freedom turn state.
