Description

Technical Field

[0001] The utility model relates to the technical field of cigarette processing equipment, in particular to a connection structure of a passive wheel assembly and a bearing seat of a European guide shuttle vehicle. Background Art

[0002] Tobacco industry enterprises widely use box-type tobacco storage equipment in the stage of conveying finished tobacco. Among them, the Oudao shuttle car is a semi-automatic shuttle car used for high-density, multi-depth finished tobacco box storage, which can operate in a three-dimensional channel. Its advantages are that it solves the problems of dense storage and fast access, greatly improves storage density, and significantly reduces the construction cost of tobacco warehouses. The wheels of the Oudao shuttle car adopt a four-wheel drive eight-wheel structure, with a total of four active wheels in the front, back, left and right. Each active wheel drives a passive wheel through a chain drive, which plays a role in uniform power distribution, large driving force, and stable operation load.

[0003] During actual operation, the passive wheel assembly of the European shuttle car often detaches from the bearing seat. The reason is that the bearing is limited by an external retaining spring on the outside of the sprocket shaft of the passive roller sprocket of the passive wheel assembly. During operation, the sprocket shaft of the passive roller sprocket moves axially, which will cause the external retaining spring on the sprocket shaft to detach from the retaining spring groove on the sprocket shaft due to the axial force, causing the passive roller sprocket and the passive wheel to immediately detach from the track, affecting normal production and posing a major safety hazard. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art and provides a connection structure between a passive wheel assembly and a bearing seat of a European guide shuttle vehicle, so as to effectively prevent the passive wheel assembly from leaving the track and eliminate potential safety hazards.

[0007] As a preferred solution for the above-mentioned connection structure, the locking end cover is provided with two mounting holes, and the outer end of the sprocket shaft is provided with two threaded holes. Two locking screws are respectively passed through the two mounting holes and then tightened in the two threaded holes of the sprocket shaft to achieve locking installation of the locking end cover and the sprocket shaft.

[0008] As a preferred solution of the above-mentioned connection structure, the mounting hole on the locking end cover is a countersunk hole, and the head of the locking screw is sunk into the countersunk hole.

[0009] As a preferred solution of the above-mentioned connection structure, a circle of limiting grooves is formed on the inner side wall of the installation channel of the bearing seat, and the retaining ring is embedded in the limiting grooves.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] The utility model provides a connection structure between the passive wheel assembly and the bearing seat of the European shuttle vehicle. By setting a locking end cover on the extended section of the sprocket shaft, the outer limit position of the inner ring of the bearing on the sprocket shaft is limited by the locking end cover, which can effectively prevent the sprocket shaft from detaching from the bearing, thereby preventing the passive wheel assembly from detaching from the track, eliminating safety hazards, and ensuring the safe operation of the equipment. In addition, the locking end cover and the extended section of the sprocket shaft are connected by two locking screws, which further ensures the stability of the connection between the two.
