Abstract
The invention discloses an improved connection device for a rack rail axle of a walking box. The improved connection device comprises the rack rail axle, an anti-rotation cover and a connection cover, the two ends of the rack rail axle are fixedly connected with the anti-rotation cover and the connection cover, the anti-rotation cover and the connection cover are square in appearance, the four corners of the anti-rotation cover and the four corners of the connection cover are provided with extending protruding lugs, the interior of the rack rail axle is connected with the connection cover through a screw, the connection cover is fixedly arranged on a large end cover, a cylindrical flange is embedded in an inner hole of the larger end cover, an anti-rotation groove having the same appearance as the connection cover is formed in the end face of the right side of the large end cover, and a through straight hole is formed in the end, making contact with the connection cover, in the rack rail axle. The connection cover is arranged on the large end cover, and the through straight hole is formed in the end, so that the problems that insufficient rigidity and strength of a stepped inner hole of a rack rail axle lead to fracture damage and maintenance is not convenient because a connection cover is embedded in a base plate in the prior art are solved, and the rack rail axle is high in connection strength, good in rigidity and convenient to install, dismount and maintain, and has the advantage of being simple in structure.
Description
Technical field
The invention belongs to a kind of Coal Mechanical field, particularly the walking case rack rails wheel axle structure safeguarded of high, the good rigidly of a kind of intensity and being convenient to.
Background technique
Traveller be coal winning machine mobile carry out mechanism itself once go wrong and will whole coal winning machine be caused out of service, have a strong impact on the normal production of coal winning machine.The Placement of existing walking case rack rails wheel shaft is fixedly connected on casing by casing both sides backing plate, as shown in Figure 2, backing plate is provided with connecting cover, connecting cover is square, there is the lug of extension corner, square structure with lug can play the effect of placing rack rails wheel shaft and rotating, one end endoporus of gear shaft is set to shoulder hole, the cylindrical lip arranged in the middle of on connecting cover is embedded in ladder endoporus, play positioning action, be convenient to install, and the rack rails wheel shaft of existing shoulder hole is subject to the External Force Acting of the gear teeth because of rack rails wheel shaft, easily there is fracture and damage in shoulder hole portion, inconvenient maintenance.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of walking case rack rails wheel shaft to improve connection set, structure is simple, installing/dismounting and easy to maintenance, and intensity is high, good rigidly, to overcome the deficiency of prior art problem.
The technological scheme that the present invention takes is: a kind of walking case rack rails wheel shaft improves connection set, comprise rack rails wheel shaft, anti-hub cap and connecting cover, rack rails wheel shaft two ends are fixedly connected with anti-hub cap and connecting cover, anti-hub cap and connecting cover profile are square, there is the lug of extension corner, rack rails axle interior is connected by screw connecting cover, described connecting cover is fixedly installed on large end cap, cylindrical lip is embedded in large end plate endoporus, described large end plate its right end face is provided with the anti-rotation groove consistent with connecting cover profile, and rack rails axle interior and connecting cover contact jaw are logical straight hole.
Described connecting cover its right end face arranges groove, and depth of groove is 1 ~ 2mm, is convenient to rack rails wheel shaft location and is easy to install.
Described connecting cover flange height is 3 ~ 5mm, is convenient to connecting cover location and installing/dismounting.
Described connecting cover overall length is 8 ~ 10mm, can ensure intensity that inner hole thread connects and be connected fixing.
Beneficial effect of the present invention: compared with prior art, the present invention adopts connecting cover to be arranged on large end cap, and end is set to logical straight hole, efficiently solve the fracture damage that causes because of the rigidity of rack rails wheel shaft ladder endoporus and strength deficiency in prior art and connecting cover is embedded in the maintenance inconvenience problem that backing plate brings, achieve rack rails wheel shaft join strength high, good rigidly, installing/dismounting and easy to maintenance, and there is the simple feature of structure.
