Abstract
The invention discloses an independent rotating mechanism. The independent rotating mechanism comprises a rotating shaft, a fixing assembly, a lamp arm, a flange plate and a connecting rod, wherein the rotating shaft comprises deep groove ball bearings, hubs, a clamping piece, nuts and a shaft center, the shaft center is of a step-type structure, the pair of deep groove ball bearings and the clamping piece are sleeved on a first-step shaft of the shaft center from top to bottom and are limited and fixed through the nuts, the hubs are connected outside the deep groove ball bearings and outside the clamping piece in a sleeved mode, and the fixing assembly is located at one end of the shaft center through the connecting rod and is static relative to the flange plate; the lamp arm is installed on one side of the fixing assembly, and the rotating shaft is fixed on a tower crane hanging arm through a fixing block. According to the above method, the independent rotating mechanism is flexible in rotating, and the problem that a tower crane detecting lamp makes contact with other devices in the rotating process is avoided.
Description
Technical field
The present invention relates to technical field of medical instruments, particularly relate to a kind of EBA system independence rotating machinery.
Background technique
Prior art, additional arm assembly is used in medical instruments field, wherein detect lamp suspension device for the tower crane in Medical Instruments, the rotation of its arm carried can be followed and rotate, but other equipment may be met in operating room, operating space is subject to certain restrictions, so be badly in need of a kind of when tower crane cantilever rotates in the market, its arm that it can not be followed to carry rotates and rotates.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of independent rotating machinery, rotates flexibly, avoids tower crane to detect lamp and touch miscellaneous equipment in rotation process, expand rotation space.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: provide a kind of independent rotating machinery, comprise: running shaft, fixing-assembly, arm, flange plate and connecting rod, described running shaft comprises deep groove ball bearing, wheel hub, card, nut and axle center, described axle center is stepped construction, on first multidiameter shaft in described axle center, cover has a pair deep groove ball bearing and a card and spacing fixing by nut from bottom to up, described wheel hub is socketed in the outside of deep groove ball bearing and a card, described fixing-assembly is positioned at the one end in axle center by connecting rod, and flange plate is static relatively, described arm is arranged on the side of fixing-assembly, and described running shaft is fixed on tower crane cantilever by fixed block.
In a preferred embodiment of the present invention, the outer diameter of described wheel hub is equal to the second multidiameter shaft outer diameter in axle center.
In a preferred embodiment of the present invention, described arm is 90 degree of tubular structures of falling T-shape, and the short tube of its arm is vertically socketed in fixing-assembly, and the long tube of its arm is laterally unsettled for connecting detection lamp.
The invention has the beneficial effects as follows: the present invention can meet tower crane and detect lamp when rotated, running shaft and fixing-assembly can be relatively rotated by bearing, and the cantilever of tower crane remains static, reach the rotation of the tower crane cantilever that detection lamp can not follow it to carry and rotate, improve the rotation flexibility detecting lamp.
Accompanying drawing explanation
Fig. 1 is the internal sectional structure schematic diagram of independence rotating machinery one of the present invention preferred embodiment.
In accompanying drawing, the mark of each parts is as follows: 1, running shaft; 2, fixing-assembly; 3, arm; 4, flange plate; 5, connecting rod; 6, fixed block; 7, tower crane cantilever; 10, deep groove ball bearing; 11, wheel hub; 12, card; 13, nut; 14, axle center; 140, the first multidiameter shaft; 141, the second multidiameter shaft; 30, short tube; 31, long tube.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1, the embodiment of the present invention comprises: a kind of independent rotating machinery, comprise: running shaft 1, fixing-assembly 2, arm 3, flange plate 4 and connecting rod 5, running shaft 1 comprises deep groove ball bearing 10, wheel hub 11, card 12, nut 13 and axle center 14, axle center 14 is stepped construction, on first multidiameter shaft 140 in axle center 14, cover has a pair deep groove ball bearing 10 and a card 12 and spacing fixing by nut 13 from bottom to up, wheel hub 11 is socketed in the outside of deep groove ball bearing 10 and a card 12, fixing-assembly 2 is positioned at the one end in axle center 14 by connecting rod 5 and flange plate 4 is static relatively, arm 3 is arranged on the side of fixing-assembly 2, and running shaft 1 is fixed on tower crane cantilever 7 by fixed block 6.
Furtherly, the outer diameter of described wheel hub 11 is equal to second multidiameter shaft 141 outer diameter in axle center 14; Arm 3 is in 90 degree of tubular structures of falling T-shape, and the short tube 30 of its arm is vertically socketed in fixing-assembly 2, and the long tube 31 of its arm is laterally unsettled for connecting detection lamp.
Independence rotating machinery of the present invention in the course of the work, located by connecting rod 5 and flange plate 4 is static relatively, and arm 3 is arranged on above fixing-assembly 2, but the weight of its arm 3 is carried on tower crane cantilever 7 by running shaft 1 by its fixing-assembly 2; When tower crane cantilever 7 rotates, running shaft 1 can be relatively rotated by deep groove ball bearing 10 with fixing-assembly 2, and when arm 3 rotates, due to fixing-assembly 2, flange plate 4 is static relatively, so arm 3 can be rotated by the short tube 30 of himself.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
