Abstract

The utility model relates to a belt conveyor which comprises a driving drum, a platform and a fence, a tension device, a carrying idler, a return idler, a conveyor belt, a frame body and a receptacle trough. The carrying idler adopts a suspension type groove-shaped idler set structure; one end of each idler on two sides is installed on a fixed frame; and the other end of each idler on the two sides is respectively connected with a central idler. By adopting suspension type groove-shaped idler sets, production costs are saved; and at the same time, certain floatability exists among three idlers of a idler set, so that the idler set is provided with a self-adaptation deformation capability for a running deviation tendency of the conveyor belt, and can automatically rectify the deviation in time. Therefore, accidents of shutdown to conduct adjustments because of the deviation of the conveyor belt are avoided; and the band-edge of the conveyor belt has little abrasion; and the service life of the conveyor belt is prolonged.

Description

Belt conveyer

[technical field]

The utility model belongs to the load transfer device technical field, relates to a kind ofly except that blow tank bottom flute profile impact idler group and head, afterbody transition carrying roller group adopt fixedly posture, and the remainder carrying idler all adopts the belt conveyer of suspension type flute profile carrying roller group.

[background technology]

Existing belt conveyer, carrying idler generally is to adopt fixedly posture flute profile carrying roller group, referring to Fig. 1, one end of the carrying roller 11 of both sides is fixedly mounted on the fixed mount 10, carrying roller 11 other ends of both sides and middle carrying roller 11 are fixedly mounted on the fixed mount 10 by bearing 12, flute profile impact idler group is adopted in the blow tank bottom, and head, tail are arranged transition carrying roller group.Because the straightness accuracy that support body is installed, the parallelism, the parallelism between each carrying roller group etc. of cylinder are made and the influence of various factors such as installation end to end, are difficult to reach designing requirement, the easy sideslip of load-transfer device and be difficult to adjust.Existing remedial measures is the measures such as flute profile aligning carrier roller group, flute profile forward-tilt idler group and employing sideslip alarm switch of arranging some, has obtained the effect of certain correction sideslip.But the phenomenon of belt deflection still takes place frequently, when causing that the sideslip alarm switch is reported to the police, must shut down and adjust, the influence production of mistaking that delays work, and the band edge quick abrasion of load-transfer device, shorten service life.

[utility model content]

In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of can correct sideslip, the belt conveyer that can save production cost again in time automatically to load-transfer device.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of belt conveyer, include head roll, walk on stage and fence, take-up device, carrying idler, return idler, load-transfer device, support body and blow tank, described carrying idler adopts suspension type flute profile carrying roller group structure, one end of the carrying roller of both sides is installed on the fixed mount, and the other end of the carrying roller of both sides is connected with the carrying roller of centre respectively.

The beneficial effects of the utility model are: adopt suspension type flute profile carrying roller group; saved productive costs; simultaneously; owing to adopt suspension type flute profile carrying roller group, have certain floatability between three carrying rollers of every group of carrying roller group, the sideslip tendency of load-transfer device there is the self-adaptation deformability; can correct sideslip in time automatically; avoided owing to belt deflection is shut down the accident of adjusting, the wearing and tearing of the band edge of load-transfer device are little, long service life.

Fig. 1 is the structural representation of existing carrying idler;

Fig. 2 is a structural representation of the present utility model;

Fig. 3 is the structure cutaway view of A-A face among Fig. 1.

Among the figure: 1-head roll, 2-are walked on stage and fence, 3-take-up device, 4-rainproof cover, 5-carrying idler, 6-load-transfer device, 7-return idler, 8-support body, 9-blow tank, 10-fixed mount, 11-carrying roller, 12-bearing.

[specific embodiment]

Below in conjunction with drawings and Examples the utility model is further specified.

Referring to Fig. 2 and Fig. 3, a kind of belt conveyer, include head roll 1, walk on stage and fence 2, take-up device 3, carrying idler 5, return idler 7, load-transfer device 6, support body 8 and blow tank 9, described carrying idler 5 adopts suspension type flute profile carrying roller group structure, every group of carrying roller group is made up of three carrying rollers 11, one end of the carrying roller 11 of both sides is installed on the fixed mount 10, adopts bolted connection between the carrying roller 11 of the other end of the carrying roller 11 of both sides and centre.The utility model is except that blow tank bottom flute profile impact idler group and head, afterbody transition carrying roller group adopt fixedly posture, the remainder carrying idler all adopts suspension type flute profile carrying roller group, cancel the use of flute profile aligning carrier roller group, flute profile forward-tilt idler group, saved productive costs; Simultaneously,, have certain floatability between three carrying rollers of every group of carrying roller group, the sideslip tendency of load-transfer device is had the self adaptation deformability, correct sideslip in time automatically owing to adopt suspension type flute profile carrying roller group.Through the successful Application in the many places engineerings such as Kweiyang, Zhejiang, Guangdong; the effect that belt conveyer is in use corrected sideslip automatically is very obvious; belt conveyer is shut down situation about adjusting and has not been had owing to belt deflection; the band edge wearing and tearing of load-transfer device are little; long service life has obtained good economic benefits.Belt conveyer is widely used in industries such as metallurgy, coal, building materials, chemical industry, and the conveying bulk density is 500-2500kg/m ³Various bulk materials.

Claims

1, a kind of belt conveyer, include head roll, walk on stage and fence, take-up device, carrying idler, return idler, load-transfer device, support body and blow tank, it is characterized in that: described carrying idler adopts suspension type flute profile carrying roller group structure, one end of the carrying roller of both sides is installed on the fixed mount, and the other end of the carrying roller of both sides is connected with the carrying roller of centre respectively.
