Abstract
The invention relates to conveying machinery in a coal mine, in particular to a bolt fixing connection structure used for the conveying machinery in the coal mine. The connection structure is provided with a support, a bolt, and a fixture block. An inner chamber of the support is a rotary chamber and is provide with a bar-shaped hole capable of causing the bolt head to be extended into the support, the bolt head of the bolt is placed into the support, the bolt head is positioned at a boss side of a support inner wall by rotation of the bolt, and the fixture block is placed into a clearance between the bolt and the bolt head. The bolt fixing connection structure fully changes the traditional bolt connection manner, and is used for solving problems that the bolt connection strength is not high and a threaded hole of the connection piece is prone to damage. In the connection structure, a connection support is welded on a connection body, the bolt head of the bolt is placed into the support and the connection piece is fixed and connected by the bolt and a nut. The connection structure does not need drilling the threaded hole on the connection body, which avoids being unable to assemble and disassemble the connection piece as the threaded hole is damaged, and improves the connection strength.
Description
Technical field
The present invention 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.
Summary of the invention
The connecting structure that the object of the present invention is to provide a kind of colliery conveying mechanism to use; 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 technical solution adopted for the present invention to solve the technical problems 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 invention has the beneficial effects as follows:
Connecting structure of the present invention 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.Connecting structure of the present invention 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 connecting structure of the present invention.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 colliery of the present invention 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.
