Description

Swelling articulated cylinder

Technical field

The utility model relates to the swelling articulated cylinder that a kind of band conveyor uses.

Background technology

The cylinder in existing band conveyor field adopts one-piece construction or welded structure mostly, the symmetry that all needs the strict guarantee roller tube when making and installing, and when safeguarding in the future such as need maintenances can only take the mode of integral replacing, the cost that this has just increased band conveyor has greatly restricted further promoting the use of of band conveyor greatly.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of swelling articulated cylinder that requirement is lower, the current maintenance cost is also lower to making and installing is provided.

The technical scheme that provides according to the utility model, socket tube body outside drum shaft, the drum shaft both ends offer connecting key, in being socketed with the swelling of ring-type, overlaps the drum shaft outer wall at cylindrical shell two ends places, the outer wall of cover is provided with the fin that stops to outer lug in the swelling, be socketed with the swelling overcoat of ring-type at the swelling outer wall of inside race, one end of swelling overcoat leans against on the sidewall that stops fin, in swelling, put and offer some first screws, swelling puts outward and offers second screw that cooperates with first screw, at first screw, be bolted with attachment bolt in second screw, be socketed with support ring at the swelling outer casing outer wall, the support ring outer wall is against cylinder inboard wall, be provided with the lug boss that stretches out to its axis at cylinder inboard wall, described support ring sidewall leans against on the lug boss and captives joint one with cylindrical shell, is provided with the fin that stops to outer lug at the outer wall of swelling overcoat, and described support ring leans against on the sidewall that stops fin.

Described first screw is opened in and stops on the fin.

The utility model is compared with the welded type cylinder with existing integral type cylinder, cost of manufacture is lower, and is lower to the requirement of making and install, and because be detachable structure, when current maintenance, can only change cylindrical shell and swelling overcoat, so the current maintenance cost is cheap.

Description of drawings

Fig. 1 is an integral structure scheme drawing of the present utility model.

The specific embodiment

The utility model is described in further detail below in conjunction with concrete drawings and Examples.

As shown in the figure: the utility model comprises the cylindrical shell 2 that is socketed in outside the drum shaft 1, drum shaft 1 both ends offer connecting key 11, in being socketed with the swelling of ring-type, drum shaft 1 outer wall at cylindrical shell 2 two ends places overlaps 4, the outer wall of cover 4 is provided with and stops fin 41 to outer lug in the swelling, cover 4 outer walls are socketed with the swelling overcoat 3 of ring-type in swelling, one end of swelling overcoat 3 leans against on the sidewall that stops fin 41, in swelling, offer some first screws 42 on the cover 4, offer second screw 32 that cooperates with first screw 42 on the swelling overcoat 3, at first screw 42, be bolted with attachment bolt 5 in second screw 32, be socketed with support ring 6 at swelling overcoat 3 outer walls, support ring 6 outer walls are against cylindrical shell 2 inwalls, be provided with the lug boss 21 that stretches out to its axis at cylindrical shell 2 inwalls, described support ring 6 sidewalls lean against on the lug boss 21 and captive joint one with cylindrical shell 2, the outer wall of swelling overcoat 3 be provided with to outer lug stop fin 31, described support ring 6 leans against on the sidewall that stops fin 31.

Described first screw 42 is opened in and stops on the fin 41.

During installation, swelling overcoat 3 is fixed on the support ring 6 (flange) at cylindrical shell 2 inboard two ends by the mode of welding, cover 4 is fixed together by attachment bolt 5 and swelling overcoat 3 in the swelling, drum shaft 1 is installed in the axle journal of cover 4 in the swelling, and by tighten attachment bolt 5 in swelling, overlap 4 and drum shaft 1 between produce tension force, thereby make being linked together that cover 4 and drum shaft 1 can be firm in the swelling.

Swelling articulated cylinder of the present utility model is installed on the band conveyor, drum shaft 1 is installed on the bearing installation seat of band conveyor, need change the place of service direction by the belt that overlaps 4 in attachment bolt 5, the swelling, swelling overcoat 3 is supported on band conveyor with cylindrical shell 2.

The belt of band conveyor is at the drive lower edge of driver element linear running, and when belt moves to cylindrical shell 2 places, belt pack overlays on the periphery of cylindrical shell 2, and along the periphery operation of cylindrical shell 2, thereby make that the service direction of belt is changed.In daily use as when finding that drum surface need be changed because of reasons such as wearing and tearing, only need to unscrew attachment bolt 5, so just, can eliminate the tension force between interior cover 4 of swelling and the drum shaft 1, be able to drum shaft 1, cover 4 is taken apart with cylindrical shell 2 and swelling overcoat 3 in the swelling, like this, it is just passable only to need to change cylindrical shell 2 and swelling overcoat 3, with cylindrical shell 2 and the swelling overcoat of making again 3 and drum shaft 1, cover 4 and attachment bolt 5 are linked together again in the swelling, and be installed on the band conveyor, just finish the replacing of cylinder, thereby greatly reduced the cost of daily working service.
