Abstract
The utility model relates to coal mine conveying machinery, in particular to a bolt fixing connection structure used by the coal mine conveying machinery. The connection structure is provided with a support, a bolt and a fixture block, wherein, the inner cavity of the support adopts a gyro-shaped cavity, a bar-shaped opening which can extend a bolt head into the support is arranged on the support, the bolt head of the bolt is arranged in the support, so that the bolt head is positioned on one side of a dummy club on the inner wall of the support through rotating the bolt, and the fixture block is positioned in a gap between the support and the bolt head. The coal mine conveying machinery completely changes a traditional bolt connection way, and is used for solving the problems that the bolt connection strength of the coal mine conveying machinery is low, and the threaded hole of a connection piece is easy to be damaged. The connection structure is a connecting support welded on a connecting body to position the bolt head of the bolt into the support and to fix the connecting piece through a bolt and a nut. The connection structure does not require the threaded hole to be drilled on the connecting body, so as to avoid the problem that the connecting piece can not be assembled and disassembled due to the damage of the threaded hole, and improve the connecting strength.
Description
Technical field
The utility model relates to the colliery conveying mechanism, specifically is the connecting structure that a kind of colliery conveying mechanism is used.
Background technique
At present, the colliery conveying equipment is mainly scraper conveyor, and wherein quite a lot of, traditional connecting mode that is coupled to each other of structural member is an auger shell pit on connected body, is screwed into bolt again and connects coupling; And for the colliery conveying mechanism, because the underground working inclement condition, it is relatively poor to vibrate bigger, traditional connecting mode intensity, and it is inconvenient to change mounting or dismounting, must rethink connection, to guarantee the intensity and the reliability requirement of colliery conveying equipment.
The model utility content
The purpose of this utility model is to provide a kind of colliery connecting structure that conveying mechanism is used; Be used to solve coupling the tapped hole rapid wear, be not easy to change the problem of mounting or dismounting, and improve the intensity of colliery conveying equipment Bolt Connection, satisfy the reliability requirement of colliery conveying equipment.
The technological scheme that its technical problem that solves the utility model adopts is:
The connecting structure that a kind of colliery conveying mechanism is used, this connecting structure is provided with bearing, bolt, fixture block, the bearing inner chamber is the jatharapanvartanasana cavity, have the strip shape gob that bolt head can be stretched into bearing on the bearing, the bolt head of bolt places bearing, rotate by bolt and to make bolt head be positioned boss one side on the bearing inwall, fixture block places the space between bearing and the bolt head.
The connecting structure that described colliery conveying mechanism is used, bearing is welded on the connected body, and coupling is installed on the connected body by the bolt on the bearing, and connected body, coupling are connected and fixed by bolt, nut.
The beneficial effects of the utility model are:
Connecting structure of the present utility model is different from traditional connecting mode fully, and this kind connecting structure is connection bearing of welding on connected body, bolt is installed on the bearing, by the bolt and nut fixed coupling unit.The utility model connecting structure does not need auger shell pit on connected body, avoids can't installing and removing because of the damage of tapped hole the problem of coupling, makes things convenient for the mounting or dismounting and the replacing of down-hole, and has improved the reliability and the linking intensity that connect.
Description of drawings
Fig. 1-Fig. 3 is the assembly structure schematic representation of the utility model connecting structure.Wherein, Fig. 1 is main pseudosection; Fig. 2 is left pseudosection; Fig. 3 is the A-A sectional view of Fig. 1.
Among the figure, 1 connected body; 2 couplings; 3 bearings; 4 bolts; 5 fixture blocks; 6 packing rings; 7 nuts; 8 boss; 9 bolt heads.
Embodiment
As shown in Figure 1-Figure 3, the connecting structure that the utility model colliery conveying mechanism is used is made of bearing 3, bolt 4, fixture block 5, bearing 3 is welded on the connected body 1, bearing 3 inner chambers are the jatharapanvartanasana cavity, have the strip shape gob that the bolt head 9 of bolt 4 can be stretched into bearing 3 on the bearing 3, bolt head 9 is placed on 3 li of bearings by strip shape gob, and the rotation by bolt 4 makes bolt head 9 be positioned boss 8 one sides on the bearing inwall; After bolt 4 was put well, fixture block 5 placed the space between bearing 3 and the bolt head 9, prevented that bolt 4 from rotating, and coupling 2 is connected and fixed by packing ring 6, nut 7.Bearing 3 is a foundry goods, and after the bolt head 9 that its structure can satisfy bolt 4 was put into, bolt 4 can rotate freely 90 °, and blocks bolt 4.The structure of bolt 4 can satisfy its bolt head 9 and put into bearing 3 easily, and is used with bearing 3.
When connecting, porose at connected body 1, size cooperates with bearing 3, and bearing 3 backs of packing into are concordant; After bearing 3 is packed into, be welded on the connected body 1; Bolt 4 inserts in the bearing 3, and can rotate freely 90 °, makes it just in time to be stuck in the bearing 3, puts into fixture block 5 again, prevents the rotation of bolt 4, and the hole cooperates connection with bolt 4 on the coupling 2, puts into packing ring 6, and fastening nut 7 is finished and connected assembling.
Claims (2)
1, the connecting structure used of a kind of colliery conveying mechanism, it is characterized in that: this connecting structure is provided with bearing, bolt, fixture block, the bearing inner chamber is the jatharapanvartanasana cavity, have the strip shape gob that bolt head can be stretched into bearing on the bearing, the bolt head of bolt places bearing, rotate by bolt and to make bolt head be positioned boss one side on the bearing inwall, fixture block places the space between bearing and the bolt head.
2, the connecting structure of using according to the described colliery of claim 1 conveying mechanism, it is characterized in that: bearing is welded on the connected body, and coupling is installed on the connected body by the bolt on the bearing, and connected body, coupling are connected and fixed by bolt, nut.
