Abstract
The utility model discloses a chute drum, which comprises triple telescoping of a plurality of drum bodys, between and telescoped drum bodies, inner wall on upper end of outer drum body is provided with an inner retaining ring 1 to hang inner drum body, external wall on upper end of the inner drum body is provided with an outer retaining ring 2 of external drum body backstop, external wall on lower end of inner drum body is provided with an outer retaining ring 5 that corresponds to the inner retaining ring 1 on upper end of outer drum body. Since an outer retaining ring 5 is provided on lower end of a drum body 3, concentricity of the drum body is increased, not only drum body can extend flexibly, prevent seizing between drum bodies due to lateral deviation, and reduce clearance between drum bodies, diameter of the whole chute drum is decreased.
Description
Affiliated technical field
The utility model relates to a kind of slide tube of using of being used on the charger of bulk cargos such as train or steamer shipment cement clinker.
Background technology
The flexible slide tube (highly may spread to 14M) that on large-scale bulk material cargo charger such as cement clinker, uses at present, there is more piece cylindrical shell intussusception to form, on the inwall of the upper end of the outer cylinder body between the mutually nested cylindrical shell, be provided with the inner shield ring that is used for hanging inner barrel, the outer wall of inner barrel upper end is provided with the outer back-up ring to outer cylinder body backstop, along the circumferential direction is welded with the projection that several are used for hanging on the lower end outer wall of inner barrel.The most inboard promptly first joint cylindrical shell upper end is fixed on the charger belt feeder and connects material on the groove, and outermost does not promptly save the cylindrical shell lower end and is fixed on the cylindrical shell frame, and slings by steel rope and winch, and cement slides by slipping tube, falls into the ship storehouse of its below.The height of cylindrical shell can be realized the cylindrical shell telescopic adjustment by the winch lifting.Longer owing to cylindrical shell, weight is heavier, and telescopic adjustment has some setbacks between cylindrical shell, takes place to block mutually because of the lateral deviation of outside cylindrical shell through regular meeting, needs on-call maintenance, and tube is dismantled and installation is all very inconvenient and slip.In addition, the projection welding that is used for hanging as firm the cylindrical shell case accident can take place.
Summary of the invention
The purpose of this utility model provides a kind of slide tube, can carry out telescopic adjustment swimmingly between the cylindrical shell, can solve preferably and block between the above-mentioned cylindrical shell and the caducous problem of cylindrical shell.
The slide tube that the utility model proposes, form by more piece cylindrical shell intussusception, between mutually nested cylindrical shell, the upper end inwall of outer cylinder body is provided with the inner shield ring that is used for hanging inner barrel, the outer wall of inner barrel upper end is provided with the outer back-up ring to outer cylinder body backstop, and the outer wall of inner barrel lower end is provided with the outer back-up ring that matches with the inner shield ring of outer cylinder body upper end.Because the back-up ring on the inner barrel outer wall is circumferential setting, week upwards with outer cylinder body between the gap equate, thereby can not cause the outer cylinder body lateral deviation and block.
In order to reduce the friction of material, sticking obedient one deck wear-resistant ceramic on one to the two joint cylinder inboard wall is arranged at least from inside to outside to cylinder inboard wall.
The utility model has the advantages that owing to set up the outer back-up ring of a circle on the inner barrel outer wall, improved the concentricity of cylindrical shell, not only cylindrical shell is flexibly flexible, prevents from preferably to block because of lateral deviation between the cylindrical shell, also reduced the gap between the cylindrical shell, the whole diameter that slips tube is reduced; In addition, the welding of outer back-up ring and cylindrical shell multiple spot, it is firm to connect, and can prevent that also structure is very simple, increases cost hardly because of hanging the generation of the cylindrical shell case accident that protruding not prison welding causes.Another advantage is an obedient porcelain on by cylinder inboard wall, has reduced wearing and tearing, can reduce maintenance times, increases the service life.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the above-mentioned figure, 1, inner shield ring, 2, outer back-up ring, 3, cylindrical shell, 4, the cylindrical shell frame, 5, outer back-up ring, 6, projection.
The specific embodiment
As shown in Figure 1, the utility model is that six joint cylindrical shells, 3 intussusceptions form, outside cylindrical shell does not promptly save the cylindrical shell lower end and is fixed on the cylindrical shell frame 4, and slings by steel rope and winch, and the most inboard promptly first joint cylindrical shell upper end is fixed on charger belt feeder connect material (not drawing among the figure) on the groove.Between mutually nested cylindrical shell 3, the upper end inwall of outer cylinder body is provided with the inner shield ring 1 that is used for hanging inner barrel, the outer wall of inner barrel upper end is provided with the outer back-up ring 2 to outer cylinder body backstop, outer back-up ring on the first joint cylindrical shell is the projection 6 that is welded on the cylinder body outer wall, and the outer wall of inner barrel lower end is provided with the outer back-up ring 5 that matches with inner shield ring 1 on the outer cylinder body.Sticking obedient one deck wear-resistant ceramic (not drawing among the figure) on first joint and the second joint cylindrical shell, 3 inwalls.
Claims (2)
1, a kind of slide tube, form by more piece cylindrical shell intussusception, between mutually nested cylindrical shell [3], the upper end inwall of outer cylinder body is provided with the inner shield ring [1] that is used for hanging inner barrel, the outer wall of inner barrel upper end is provided with the outer back-up ring [2] to outer cylinder body backstop, it is characterized in that the outer wall of inner barrel lower end is provided with the outer back-up ring [5] that matches with the inner shield ring [1] of outer cylinder body upper end.
2, slide according to claim 1 tube is characterized in that having at least from inside to outside that sticking card has one deck wear-resistant ceramic on one to the two joint cylinder inboard wall.
