Description

The invention relates to conveyor transport, and in particular to conveyors with hanging tape.

Known steeply inclined conveyor with a hanging belt [1], containing an envelope of the drive and end drums endless conveyor belt, on the sides of which are evenly mounted pendants, each of which is equipped with two rollers mounted with the possibility of rolling on both sides of the conveyor rails, and also pivotally connected to the suspensions load-holding partitions. The rolling guides are made of a pipe and bend around the drive and end drums, and on the load-bearing section the guides are brought together to increase the groove of the tape, and in the region of both drums are separated by a distance that ensures that the tape fits to the working surface of the drums.

The disadvantage of this conveyor is the frictional transmission of the drive force from the drive drum to the traction body, which creates the need for significant belt tension, in addition, the belt and suspensions experience additional load when they pass flat areas. A single-drum drive cannot provide a known long-distance conveyor with traction, and design features do not allow the use of a multi-drum drive. In addition, the conveyor is equipped with expensive devices of a special design to hold the load on an inclined load-bearing body.

Closest to the proposed technical solution is a curved multi-drive conveyor for vertical load lifting [2], comprising becoming with rolling guides, as well as an endless conveyor belt, on the sides of which roller suspensions are uniformly fixed, connected by an endless chain. Tubular guides are made in the form of spatial curves so that the trajectory of the tape is a helix with a vertically oriented axis and a certain number of turns. On the outside of the helical path, the conveyor is equipped with intermediate drives that transmit the drive force to an endless chain.

The disadvantages of this conveyor are the relatively low speed of the load-carrying body, due to the use of chain transmission of traction, and the complexity of this design. In addition, when the tape passes through curved sections, it develops due to the presence of a rigid connection between the suspensions from the outside of the helical path.

The objective of the invention is to develop the design of the conveyor with a hanging tape with minimal material consumption and the ability to move goods along a spatial route.

This task is achieved by the fact that the claimed invention contains a supporting metal structure with closed triangular rolling guides fixed to it on both sides of the conveyor, as well as an endless conveyor belt, which is directly or by means of intermediate elements coupled with three-roller suspensions installed with the possibility of their movement along guides.

According to the invention, the drive is distributed along the entire length of the conveyor. Suspensions are equipped with microdrives, current lead with current collectors, clamping devices that prevent the drive roller from slipping relative to the guide. Drive and non-drive suspensions alternate in increments depending on the required total drive power and the power of the selected gearmotors.

The same type of suspension is connected in pairs in a plane perpendicular to the longitudinal axis of the conveyor, with metal plates that ensure uniform movement and serve as a supporting grooved frame for the tape.

The rolling guides in curved sections are equipped with gear racks, and drive suspensions are equipped with gear wheels, which increases the adhesion of the driving body with the running gear and eliminates slipping.

When carrying out the invention, a technical result can be obtained consisting in a significant reduction in the metal consumption of the structure by eliminating the drive station from it with friction transmission of the traction force and the tension station, since the distributed drive used does not require constant tension of the belt, while the load is held in bags formed as a result of sagging of the tape between the attachment points to the suspensions. Compared with conveyors of a similar purpose, the proposed invention as a load-carrying body can be used rubber tape general purpose with less load capacity and fewer gaskets, by reducing tensile forces. Implementation of traces of complex configuration is possible.

The conveyor with a hanging tape contains a supporting metal structure 1 (Figs. 1, 2, 3) with closed rolling guides 2 of a triangular shape (Figs. 1, 2, 3 and 4) made of a steel corner and a steel plate, rack 3 (Fig. 1 , 2, 3) with a conductive circuit 4 fixed to them (Figs. 1, 2, 3, 4), gear racks 5 (Fig. 4) mounted on rolling guides 2 in curved sections.

Non-driven 6 (figure 1, 2, 3, 4) and drive 7 (figure 1, 2, 3, 4) suspensions are paired with metal plates 8 (figure 3), to which an endless conveyor belt 9 is attached (figure 1 , Fig.2, Fig.3).

Non-drive suspension 6 (Fig. 4) consists of two cheeks 10 (Fig. 5, 6, 7), a rod 11 (Fig. 5, 6, 7) for connecting with a metal plate 8 (Fig. 4), three roller assemblies 12 (figure 5, 6, 7), each of which is installed in the clip 13 (figure 5, 6, 7).

Drive suspension 7 (Fig. 4) includes two cheeks 10 (Fig. 8, 9, 10), a rod 11 (Fig. 8, 10), two roller assemblies 12 (Fig. 8, 9, 10) inserted into the cage 13 (Fig. 8, 9, 10), and the drive roller is a gear wheel 14 (Fig. 8, 9, 10), mounted on the shaft of the gear motor 15 (Fig. 8, 9, 10), the current collector 16 (Fig. 8 , 9, 10) and the clamping device 17 (Fig. 8, 9, 10).

The conveyor with a hanging tape works as follows. The electric current supplied to the current-supply circuit 4 (Fig. 1, 2, 3, 4), through the current collectors 16 (Fig. 8, 9, 10) drives the gear motors 15 (Fig. 8, 9, 10), rotating drive rollers - gears 14 (Fig. 8, 9, 10), which are pressed by the clamping device 17 (Fig. 8, 9, 10) to the rolling guides 2 (Figs. 1, 2, 3 and 4) to avoid slipping in curved sections are engaged with the gear rack 5 (figure 4). In this case, the generated traction is given to the drive suspensions 7 (Fig. 1, 2, 3, 4), which carry the tape 9 (Fig. 1, Fig. 2, Fig. 3) by means of metal plates 8 (Fig. 3), attached to it. In turn, the tape 9 also carries away non-drive pendants 6 (Figs. 1, 2, 3, 4), transmitting traction through metal plates 8 to them.

The technical and economic advantage of the claimed invention lies in the fact that the use of a distributed drive makes it possible to exclude from the conveyor structure the head drive station, the tension station, the flat sections of the rolling guides, which create additional load on the belt and suspensions. All this ensures the relative simplicity of the design and the reduction of its metal consumption, increased durability and the possibility of choosing a less expensive low-strength conveyor belt. In addition, the claimed conveyor with distributed drive allows you to implement routes of complex configuration for any length of the conveyor, performance and characteristics of the transported cargo.
