Abstract
The utility model discloses an independently rotating mechanism. The mechanism comprises a rotating shaft, a fixing component, a lamp arm, a flange plate and a connection rod. The rotating shaft comprises deep groove ball bearings, a hub, a snapping sheet, a nut and a shaft center. The shaft center is in a stepped structure, a pair of the deep groove ball bearings and the snapping sheet are sleeved on a first stepped shaft of the shaft center from the bottom to the top and limited and fixed through the nut, the hub is sleeved on the outsides of the deep groove ball bearings and the snapping sheet, the fixing component is positioned at one end of the shaft center through the connection rod and is static relative to the flange plate; the lamp arm is mounted on one side of the fixing component, and the rotating shaft is fixed on a crane cantilever through a fixing block. By means of the independently rotating mechanism, rotation is flexible, and a crane detection lamp is prevented from impacting on other devices during rotation.
Description
Technical field
The utility model relates to technical field of medical instruments, particularly relates to a kind of EBA system independence rotating machinery.
Background technique
Prior art, the additional arm assembly is for medical instruments field, wherein the tower crane for Medical Instruments detects the lamp suspension device, can follow the rotation of its arm carried and rotate, but may meet other equipment in operating room, operating space is subject to certain restrictions, so be badly in need of in the market a kind ofly when the tower crane cantilever rotates, arm that it can not follow it to carry rotates and rotates.
The model utility content
The technical problem that the utility model 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, has enlarged rotation space.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of independent rotating machinery is provided, 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, overlap from bottom to up on first multidiameter shaft in described axle center a pair of deep groove ball bearing and a card spacing fixing by nut are arranged, described wheel hub is socketed in the outside of deep groove ball bearing and a card, described fixing-assembly is positioned at an end in axle center by connecting rod, and flange plate is static relatively, described arm is arranged on a side of fixing-assembly, and described running shaft is fixed on the tower crane cantilever by fixed block.
In preferred embodiment of the utility model, the outer diameter of described wheel hub is equal to the second multidiameter shaft outer diameter in axle center.
In preferred embodiment of the utility model, described arm is the 90 degree tubulose of falling T-shape structures, and the short tube of its arm vertically is socketed in fixing-assembly, and the long tube of its arm is laterally unsettled for connecting the detection lamp.
The beneficial effects of the utility model are: the utility model can meet tower crane and detect lamp when rotated, running shaft and fixing-assembly can relatively rotate by bearing, and the cantilever of tower crane remains static, reach the detection lamp and can not follow the rotation of its tower crane cantilever carried and rotate, improved the rotation flexibility that detects lamp.
The accompanying drawing explanation
Fig. 1 is the inside sectional structure schematic diagram of the utility model independence rotating machinery one 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 utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Refer to Fig. 1, the utility model is embodiment comprise: 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, overlap from bottom to up on first multidiameter shaft 140 in axle center 14 a pair of deep groove ball bearing 10 and a card 12 spacing fixing by nut 13 are arranged, wheel hub 11 is socketed in the outside of deep groove ball bearing 10 and a card 12, fixing-assembly 2 is positioned at an end in axle center 14 by connecting rod 5 and flange plate 4 is static relatively, arm 3 is arranged on a 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 diameters in axle center 14; Arm 3 is the 90 degree tubulose of falling T-shape structures, and the short tube 30 of its arm vertically is socketed in fixing-assembly 2, and the long tube 31 of its arm is laterally unsettled for connecting the detection lamp.
In the course of the work, flange plate 4 is static relatively by connecting rod 5 location for its fixing-assembly 2 for the utility model independence rotating machinery, 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; When 7 rotation of tower crane cantilever, running shaft 1 can relatively rotate by deep groove ball bearing 10 with fixing-assembly 2, when arm 3 rotates, because the relative flange plate 4 of fixing-assembly 2 is static, so arm 3 can rotate by the short tube 30 of himself.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
