Abstract
The invention relates to a rotary table specially used for a boom-type roadheader in the field of road-heading machines for mining use. The rotary table comprises a rotary-table main body. A connecting tie bar is arranged between the root parts of inner fulcrums of fulcrums of two cutting motors at the left side and the right side of the rotary-table body. The connecting tie bar and the rotary-table body are arranged into an integrated structure. The rotary table can effectively avoid deformation of the fulcrums for connecting the cutting motors in a casting process, and can effectively prolong the service lifetime of the rotary table.
Description
[technical field]
The present invention relates to mining development machine field, especially relate to a kind of panoramic table specially applied in the boom-type roadheader of colliery.
[background technology]
Known, because the working environment in colliery is comparatively severe, the geological conditions of coal mine roadway is comparatively complicated, therefore, all parts for extractive equipment development machine conventional in colliery all has higher quality requirement, wherein, because panoramic table is the base apparatus that development machine carries out coal mining activity, it can play crucial carrying and connection function, so the performance of panoramic table directly can have influence on the operating efficiency of development machine; At present, the panoramic table that existing development machine uses is roughly divided into welded construction and two kinds, monoblock cast structure, wherein, because the intensity of welded intensity relative overall cast structure is weaker, therefore, what substantially use now is all the panoramic table of monoblock cast structure; But; because existing casting technique is relatively also not bery perfect; so the panoramic table cast out also to have ratio of defects higher; the problem that yield rate is lower; such as: existing panoramic table deforms in casting process for the fulcrum that connects cutting motor is not only easy; thus cause the casting dimension cast out not meet instructions for use; and the root of this fulcrum also often can stress be concentrated and occur crackle in the process of application panoramic table; this greatly reduces the application life of panoramic table, adds corresponding financial burden to user.
[summary of the invention]
In order to overcome the deficiency in background technology, the invention discloses a kind of boom-type roadheader special turntable, described panoramic table not only effectively can avoid the fulcrum for connecting cutting motor to occur distortion in casting process, but also effectively can improve the application life of panoramic table.
For achieving the above object, the present invention adopts following technical scheme:
A kind of boom-type roadheader special turntable, described panoramic table comprises panoramic table body, is provided with a connection lacing wire between the inner-support root of two cutting motor fulcrums of this panoramic table body left and right sides, and this connection lacing wire and panoramic table body are set to integrative-structure.
Further, described connection lacing wire correspondence connects the afterbody upper end being positioned at two cut hoist cylinder fulcrums of the same side with two cutting motor fulcrums.
Further, all wear-resistant sleeve is set with in the pin shaft hole of two cutting motor fulcrums in described panoramic table body and four sections of evil hoist cylinder fulcrums.
Owing to adopting technical scheme as above, the present invention has following beneficial effect:
Boom-type roadheader special turntable structure of the present invention is simple, is easy to casting; Described panoramic table effectively adds the bulk strength of panoramic table by the connection lacing wire arranged between the cutting motor fulcrum of two, left and right, and in the use procedure of panoramic table, protection is defined to pivoting support, thus reach the object improving panoramic table application life; In addition, the connection lacing wire of setting up effectively can also ensure in casting process that the cutting motor fulcrum of panoramic table can not deform, this not only can be beneficial to the casting size ensureing foundry goods, and can also effectively avoid forming the casting flaws such as shrinkage porosite, shrinkage cavity or cold cracking in foundry goods cooling procedure after pouring.
[accompanying drawing explanation]
Fig. 1 is schematic diagram of the present invention.
In figure: 1, panoramic table body; 2, cutting motor fulcrum; 3, inner-support root; 4, lacing wire is connected; 5, cut hoist cylinder fulcrum.
[detailed description of the invention]
Can explain the present invention in more detail by the following examples, disclose object of the present invention and be intended to protect all changes and improvements in the scope of the invention, the present invention is not limited to the following examples:
Boom-type roadheader special turntable by reference to the accompanying drawings described in 1, described panoramic table comprises panoramic table body 1, a connection lacing wire 4 is fixed with between the inner-support root 3 of two cutting motor fulcrums 2 of panoramic table body 1 left and right sides, this connection lacing wire 4 is set to integrative-structure with panoramic table body 1, namely the horizontal cantilever part of two cutting motor fulcrums 2 is effectively shortened in the connection lacing wire 4 by setting up, make two cutting motor fulcrums 2 in the application process of panoramic table, become an overall structure, also utilization connection lacing wire 4 effectively alleviates the stress suffered by two inner-support roots 3 simultaneously, thus not only reach the object strengthening panoramic table bulk strength, and effectively prevent the too early appearance crackle of inner-support root 3, the corresponding application life that improve panoramic table, as required, described connection lacing wire 4 correspondingly can connect the afterbody being positioned at two cut hoist cylinder fulcrums 5 of the same side with two cutting motor fulcrums 2, thus reach the object increasing panoramic table bulk strength further, simultaneously, such vibrational power flow, two cutting motor fulcrums 2 that can make to be arranged in panoramic table body 1 homonymy and two cut hoist cylinder fulcrums 5 the process of casting panoramic table corresponding become as a whole, thus not only effectively reach and avoid corresponding fulcrum to deform in casting process and ensure the object of panoramic table cast casting size, but also transition is defined between the position of panoramic table foundry goods different-thickness, this effectively avoids in panoramic table foundry goods cooling procedure after pouring and forms shrinkage porosite, the casting flaw such as shrinkage cavity or cold cracking,
In addition, the connection lacing wire 4 increased can form protection to pivoting support in the use procedure of panoramic table complete machine, thus effectively avoid the thing such as water or dust and directly fall pivoting support, and enter pivoting support destruction lubricating grease quality or be attached on raceway, and then reach the object improving pivoting support application life; As required, all wear-resistant sleeve is set with in the pin shaft hole of two the cutting motor fulcrums 2 in described panoramic table body 1 and four sections of evil hoist cylinder fulcrums 5, thus effectively enhance the rub proofness of pin shaft hole, this not only can reduce the maintenance frequency of panoramic table body, and can extend the application life of described panoramic table accordingly.
Part not in the detailed description of the invention is prior art, therefore the present invention is not described in detail.
