RU2287472C1 - Overhead belt conveyor - Google Patents

Abstract

FIELD: mechanical engineering; materials handling facilities.

SUBSTANCE: invention relates to overhead belt conveyors for transportation of lump and loose loads. Proposed conveyor contains posts, endless belt closed on drum forming carrying and return runs, disk rollers with rounded off rims installed on posts for rotation of axles and supporting the belt. Sides of belt are made with projections pointed inwards the contour. Return run of belt is arranged under carrying run with deflection providing arrangement of disk rollers between sides of carrying and return runs of belt with orientation of disk rollers in vertical plane and possibility of thrusting against projections of sides from side of longitudinal axis of belt. Cylindrical rollers are arranged from outer sides of carrying and return runs for rotation of axles and engaging with sides of belt. Each disk roller is arranged between cylindrical rollers in one vertical plane.

EFFECT: simplified design of conveyor and reduced cost owing to decrease of number of design components and provision of catching of both runs of broken belt of inclined conveyor.

Description

The invention relates to conveyor engineering, and in particular to belt conveyors with hanging tape for transporting lumpy and bulk cargoes.

Known belt conveyors with hanging tape, including a conveyor belt infinitely closed in a vertical plane on the drums, two flexible elements infinitely closed on drive, tension and deflecting pulleys in the form of traction-carrying ropes with the possibility of supporting the conveyor belt sides on them, disk rollers with the possibility of support on them are ropes, a frame (Spivakovsky A.O., Dyachkov V.K. Transporting machines. M: Mashinostroenie, 1983, p. 158-159, fig. 4.47).

The disadvantages of the known conveyors are the complexity of the design, the limitation of the cross-sectional area of the conveyor belt tray, the inability to catch the broken tape of the inclined conveyor.

Known belt conveyor with a hanging tape (prototype), containing racks, endlessly closed on the drums of the tape with the formation of load-bearing and non-working branches and resting its sides on the straps of a T-shaped profile in cross section, while the belts are placed with the possibility of supporting their shelves on a working non-working branches on two disk rollers with rounded rims, which are installed perpendicular to each other and placed symmetrically relative to the belt, and the sides of the tape with the belts are connected by brackets connected between Fighting with fingers (Pat. RF No. 2170696, class B 65 G 15/08, 2001).

The disadvantages of the known conveyor are the complexity of the design and the inability to catch the broken tape of an inclined conveyor.

The technical result of the invention is to simplify and reduce the cost of the conveyor design by reducing the number of structural elements and providing the possibility of catching the broken tape of the inclined conveyor.

The technical result is achieved by the fact that in a conveyor belt with a hanging tape containing racks, an endlessly closed tape on the drums with the formation of load-bearing and non-working branches, disk rollers with rounded rims mounted on the racks with the possibility of their rotation on the axes and maintaining the belt, according to the invention of the bead made with protrusions facing the inside of its contour, the non-working branch of the tape is placed under the load-bearing branch with a deflection that ensures the placement of disk rollers between the sides of the load-bearing non-working branches of the tape with the orientation of the disk rollers in a vertical plane and the possibility of abutment in the protrusions of the sides from the side of the longitudinal axis of the tape, and on the outer sides of the load-bearing and non-working branches of the tape are arranged to rotate on the axes and interact with the sides of the tape cylindrical rollers, and the disk roller is placed between cylindrical rollers in one vertical plane.

A conveyor belt with a hanging tape is shown in the drawing - cross section.

The conveyor belt with hanging tape contains racks 1, endlessly closed on the reels (not shown) of the tape with the formation of a load-carrying 2 and non-working 3 branches. The sides of the tape (2, 3) are made with protrusions 4 facing the inside of its contour. In this case, the non-working 3 branch of the tape is placed under the load-bearing branch 2 of the tape with a deflection that ensures that the disk rollers 5 are placed between the sides. Disk rollers 5 are oriented in a vertical plane and mounted on racks 1 with the possibility of rotation on the axles 6 and abutting against the protrusions 4 of the sides of the load-carrying 2 and non-working 3 branches of the tape from the side of the longitudinal axis 7 of the tape. On the outer sides of the load-carrying 2 and non-working 3 branches of the tape with the possibility of rotation on the axes 8 and 9 and interacting with the sides of the mentioned tape branches on the racks 1 there are mounted a cylindrical roller 10 above the load-carrying branch 2 of the tape and a cylindrical roller 11 under the non-working branch 3 of the tape. Moreover, each disk roller 5 is placed between the cylindrical rollers 10 and 11 in one vertical plane, i.e. rollers 5, 10 and 11 are placed under each other. 12 - transported cargo.

Belt conveyor with hanging tape operates as follows. The pulling force from the drive drum is transmitted to the load-carrying branch 2 of the belt with the transported load 12. The transverse tension from the weight of the load-carrying branch of the belt and the weight of the transported load 12 is transmitted to the disk rollers 5 located on the side of each side of the belt, and the lateral tension from the weight of the non-working branch 3 of the tape is transmitted to the disk rollers 11. Since the cylindrical roller 10 is located on the outside of the load-bearing branch 2 of the tape directly above the disk roller 5, and the cylindrical roller 11 is placed with the non-working side of the non-working branch 3 of the tape directly under the disk roller 5, reliable fixation of the sides of the tape in the transverse directions is provided when both its branches 2 and 3 are moving. When the belt of the inclined conveyor breaks due to the interaction of the disk rollers 5 simultaneously with both branches 2 and 3, which after the breakage of the tape will move in one direction, capture of both branches 2 and 3 of the tape will take place by friction between the disk rollers 5 and the inner surfaces of the load-carrying 2 and non-working 3 branches of the tape.

Distinctive features of the invention provide a simplification and cheaper construction of the conveyor by reducing the number of structural elements and providing the ability to capture both branches of the broken tape of an inclined conveyor.
