The utility model has the advantages of can effectively reduce equipment failure rate, reduce maintenance personal amount of labour and avoid safe risk coefficient, improve joint strength, improve the running quality of reamer.
Description
Technical Field
The utility model relates to a buggy preparation equipment field especially relates to buggy preparation transports reamer flange's improvement technique.
Background
The ten thousand ton line buggy preparation is transported reamer flange and is the mode of 2 hole rhombus erection joints, as shown in fig. 3, 4, appears reamer bolt fracture easily in daily operation in-process, hangs the tile and changes the installation and look for the poor scheduling problem, leads to the reamer fault rate high, has increased safe risk coefficient in the frequent processing procedure.
Disclosure of Invention
The utility model aims to solve the technical problem that realize one kind can reduce equipment fault rate, reduce maintenance personal amount of labour, improve the flange structure that the reliability was transported in buggy preparation.
In order to realize the purpose, the utility model discloses a technical scheme be: the utility model provides a rimer flange is transported in buggy preparation, ring flange and rotor shaft rigid coupling, the rigid coupling has the rimer on the rotor shaft, be equipped with on the ring flange be used for with hang the tile connecting hole, the ring flange is circular, follows ring flange a week is equipped with 4-8 connecting holes, the ring flange is connected with hanging the tile through the bolt that runs through the connecting hole, one of them face rigid coupling of ring flange has the pipe box, be equipped with the complex pinhole on pipe box and the rotor shaft, the rotor shaft inserts pin and the pipe box rigid coupling through running through the pinhole in the pipe box.
The connecting holes are 6 and arranged at equal included angles.
At least two groups of pin holes are arranged.
The length of the pipe sleeve is 400-600 mm.
And at least two reinforcing ribs are arranged at the joint of the pipe sleeve and the flange plate, and the reinforcing ribs are welded on the pipe sleeve and the flange plate.
The reinforcing rib is a metal plate with a right-angled triangle, and two right-angled edges of the metal plate are respectively welded on the pipe sleeve and the flange plate.
The utility model has the advantages of can effectively reduce equipment failure rate, reduce maintenance personal amount of labour and avoid safe risk coefficient, improve joint strength, improve the running quality of reamer.
At present, a reamer rotor hanging tile of a ten thousand-ton line coal grinding system is completely replaced, so that at present, the failure rate of a reamer is obviously reduced, the daily maintenance workload is greatly reduced, the operation control degree of equipment is obviously improved, and the technical improvement effect is obvious.
Drawings
The following brief descriptions of the contents expressed by each figure and the marks in the figures in the specification of the present invention are as follows:
FIGS. 1 and 2 are schematic structural views of a modified flange face;
FIGS. 3 and 4 are schematic structural views of a modified front flange face;
the labels in the above figures are: 1. a flange plate; 2. connecting holes; 3. pipe sleeve; 4. reinforcing ribs; 5. a pin hole; 6. a rotor shaft.
Detailed Description
The following description of the embodiments with reference to the drawings is intended to illustrate the present invention in further detail, such as the shapes and structures of the components, the mutual positions and connections between the components, the functions and working principles of the components, the manufacturing process, and the operation and use methods, etc., so as to help those skilled in the art understand the present invention more completely, accurately and deeply.
As shown in fig. 1-4, the flange plate 1 of the connection flange of the pulverized coal preparation transfer reamer is changed from the original diamond flange with two connection holes 2 to the original diamond flange with 4-8 connection holes 2, preferably 6 connection holes 2, wherein the six connection holes 2 are arranged on the periphery of the flange plate 1 at equal included angles, the hanging tile of the reamer rotor is fixed on the flange plate 1 through bolts, and the reamer does not have faults caused by the problems of bolt connection and the like due to the increase of the connection strength.
The flange plate 1 and the rotor shaft 6 are additionally provided with 400-plus 600mm sleeves to improve the strength, the length of the sleeve is preferably 500mm, one surface of the flange plate 1 is fixedly connected with the pipe sleeve 3, the pipe sleeve 3 is provided with pin holes 5, the rotor shaft 6 is also provided with pin holes 5, the positions of the pin holes 5 on the sleeve are matched with the positions of the pin holes 5 on the rotor shaft 6, the rotor shaft 6 is inserted into the pipe sleeve 3 and fixedly connected with the pipe sleeve 3 through pins penetrating through the pin holes 5, and the pin holes 5 are preferably provided with two groups.
At least two reinforcing ribs 4 are arranged at the joint of the pipe sleeve 3 and the flange plate 1, 4-8 reinforcing ribs are generally arranged, the reinforcing ribs 4 are metal plates in a right-angled triangle shape, and two right-angled edges of the metal plates are respectively welded on the pipe sleeve 3 and the flange plate 1. Through multiple improvement structure enhancement, flange joint position reaches the operating cycle, does not appear bolt fracture in operation, and the hanging tile rocks the phenomenon from top to bottom, operates steadily, and follow-up cleaver is carried out platform by platform technical change again, does not take place because of the cleaver hanging tile bolt breakage causes rotor scale card jump stop the scheduling trouble, and the hanging tile is examined when the utilization shut down that present workshop section has the planning, and the hanknife fault rate descends more than before the technical change, greatly reduced post personnel's amount of labour and safe risk coefficient.
The present invention has been described above with reference to the accompanying drawings, and it is to be understood that the invention is not limited to the specific embodiments described above, and that the invention is not limited to the specific embodiments described above, but rather is intended to cover various insubstantial modifications of the inventive method and solution, or its application to other applications without modification.
