Description

The invention relates to a wire conveyor belt made of any wire. Wire conveyor belt is used as a continuous transport for transporting materials, parts and products. A conveyor belt made of heat-resistant alloy wire is used as a load-carrying equipment in thermal units during transportation of parts and products during their heat treatment in high-temperature environments. The conveyor belt can be used in kilns, in drying drums, in any production with processes of roasting, drying, heat treatment, etc. in thermal units of both domestic and foreign production.

A known design of a wire conveyor belt, the web of which is made of flat double spirals of alternating left and right weaving directions, over the entire width of the belt, articulated between them by U-shaped transverse rods (prototype - Gagloev N.A. Wire conveyor belt with U-shaped transverse rods and method for its manufacture, RF patent No. 2112729, 08/30/96).

To ensure the straightness of movement of the conveyor belt and to increase its strength, it is assembled alternately from flat double spirals of the left and right weaving direction.

Each double spiral (ribbon link) represents two spirals of the same direction of weaving woven into each other: a flat double spiral of the left direction of weaving consists of two flat spirals of the left direction of weaving with winding them together; the flat double spiral of the right direction of weaving consists of two flat spirals of the right direction of weaving with their winding together. With double spirals, the number of articulated joints of spirals with transverse rods increases, which ensures the expansion of the field of use of the tape for any diameter of the conveyor drums.

The alternation of spirals of the left and right direction of weaving during the operation of the conveyor belt eliminates the convergence of the belt in one direction or the other, and accordingly eliminates the destruction (wrinkling) of the edges of the belt and its wear due to the increase of friction of the edges of the belt on the flanges of the drums and rollers during longitudinal convergence of the belt,

Double winding spirals increase the carrying capacity of the tape, reduce the “transparency” of the tape.

Flat double spirals of the conveyor belt web are connected in a single design by U-shaped transverse rods protruding behind the spirals, which prevents the spirals from breaking when the belt moves along the drums and conveyor rollers. The design feature with U-shaped transverse rods in the alternation of sections (links) along the longitudinal edges of the belt, not connected by the ends of the transverse rods, which ensures the linearity of movement of the conveyor belt in operation, uniform extension of the belt when it moves without changing geometric dimensions, without distortions, without transverse narrowing under load, and also increases the elasticity of the tape.

The disadvantages of the tape are:

- the absence of limiters along the longitudinal edges of the tape to prevent cargo from sliding from the surface of the tape web during transportation, especially when transporting small parts and products (needles, blades, washers, coins, buttons, etc.) and materials of small fractions;

- "transparency" of the tape web;

- the mobility of the turns of spirals across the tape. The proposed technical solutions aim:

- increase the strength data of the conveyor belt;

- expanding the use of conveyor belts;

- expanding the operational capabilities of the conveyor belt;

- reducing the complexity of manufacturing the tape;

- obtaining an economic effect.

This goal is achieved by the fact that the wire conveyor belt comprises transverse double spirals of alternating left and right weaving direction, which are pivotally connected by transverse rods inserted into the joints of double spirals of the left and right direction of weaving, located across the longitudinal axis of the conveyor belt to the width of the belt and parallel to each other forming links, while the extreme turns of the spirals are fixed on the transverse rods. The tape has elements for filling the gaps of the spirals in each link of the tape to the width of the latter, while along its both longitudinal edges for the entire length of the tape, it has sides made in the form of bends at both ends of the transverse rods and elements for filling the gaps of the spirals to the side height.

The extreme turns of the spirals are fixed on the transverse rods by bending around them without welding or with welding to the elements to fill the gaps of the spirals.

Elements for filling the gaps of the spirals in each link of the tape to the width of the latter are made in the form of transverse plates, while the sides of the tape along its longitudinal edges are made in the form of bends of both ends of the transverse rods and transverse plates up to the height of the side.

The transverse rods are made of bent wire in the longitudinal direction to protect the coils of the spirals from being displaced across the tape.

Elements for filling the gaps of the spirals in each link of the tape to the width of the latter are made in the form of additional transverse rods, preferably of smooth wire, located close to each other, while the sides of the tape along its longitudinal edges are made in the form of bends at both ends of the transverse rods and additional transverse rods up to the height of the side.

The transverse rods are made of a bent wire in the longitudinal direction to protect the coils of the spirals from being displaced across the tape, while the additional transverse rods are preferably made of smooth wire.

The proposed conveyor belt can be performed as follows:

1) Wire conveyor belt from double spirals of alternating left and right direction of weaving, with transverse rods, with transverse plates to fill the gaps of spirals, with sides.

2) A wire conveyor belt of double spirals of alternating left and right direction of weaving with transverse rods from a wire of a bent profile in the longitudinal direction, with transverse plates to fill the gaps of the spirals, with sides.

3) Wire conveyor belt of double spirals of alternating left and right direction of weaving with transverse rods, with additional transverse rods to fill the gaps of the spirals, with sides.

4) A wire conveyor belt of double spirals of alternating left and right direction of weaving with transverse rods from a wire of bent profile in the longitudinal direction, with additional transverse rods to fill the gaps of the spirals, with sides.

1. A wire conveyor belt of double spirals of alternating left and right direction of weaving, with transverse rods, with transverse plates to fill the gaps of spirals with sides.

The drawings show the design features of a wire conveyor belt of double flat spirals of alternating left and right weaving direction, with transverse rods, with transverse plates to fill the gaps of the spirals, with sides (Fig. 1 - Fig. 6, Fig. 8).

The wire conveyor belt (Fig. 1) is a web assembled from double flat spirals of measured length depending on the width of the belt, alternating left (1l) and right (1p) weaving directions, pivotally interconnected by transverse rods (Fig. 6, pos. .2) inserted into the joints of the left and right weaving spirals.

To expand the area of use of wire conveyor belts with transverse rods and expand their operational capabilities, the belt is equipped with elements for filling the gaps of spirals and sides.

The sides of the tape are made in the form of a bend up to the height of the sides of the transverse rods and filling elements (transverse plates) along one longitudinal edge of the tape in the manufacture of transverse rods (Fig.6) and transverse plates (Fig.8); along the second longitudinal edge of the tape by bending the rods and plates during shaping of the longitudinal edge of the tape during its assembly.

The sides of the tape protect parts and products from slipping from the surface of the tape web when the tape moves in the conveyor, expand the useful area of use of the tape web.

To ensure almost zero “transparency” of the tape, it is equipped with elements for filling the gaps of the spirals from the transverse plates (4), which allows the transportation of small and very small parts, products and materials of small fractions,

Transverse plates (Fig. 8, pos. 4) with one end bent to the side height during assembly are inserted into each link of the tape in the transverse direction into the gaps of the spirals.

The second end of the transverse plates for the formation of the bead is bent to the height of the bead during shaping of the longitudinal edge of the tape during its assembly.

The ends of the extreme turns of the spirals are bent around the transverse rods (pos. 2, 3) without welding (Fig. 4) or with welding to the filling elements (Fig. 5).

The bending of the extreme turns of the spirals around the transverse rods increases the strength of the wire conveyor belt, reduces the narrowing of the tape in the transverse direction, gives a linear movement of the tape when it is under load.

Vertical elements of the side of the tape prevent the descent of the extreme turns of the spirals. Ball welding is eliminated, which significantly reduces the complexity of manufacturing the tape.

2. A wire conveyor belt of double spirals of alternating left and right weaving direction, with transverse rods from a wire of a bent profile in the longitudinal direction, with transverse plates to fill the gaps of the spirals, with sides.

The drawings show the structural features of the tape (Fig.1 - Fig.5, Fig.7, Fig.8). The general plan of the conveyor belt and the view of the longitudinal edge of the belt with sides are similar to those of FIG. 1 and FIG. 2, respectively.

By design solutions, the conveyor belt differs from the main belt in the execution of transverse rods of bent profile wire in the longitudinal direction.

The turns of the spirals have mobility in the transverse direction of the belt web when it moves in the conveyor. The transverse rods of the wire bent profile in the longitudinal direction (Fig.7, pos.3) protect the coils of the spirals from displacement. The bent profile of the rod is made with rounded, triangular, trapezoidal, etc. waves. In places of maximum bending, the waves of the core of the spiral are paired with transverse rods.

With transverse rods made of wire of a bent profile in the longitudinal direction, the pitch of the spirals can be increased, which reduces the metal consumption of the tape and gives an economic effect.

3. A wire tape made of double spirals of alternating left and right direction of weaving, with transverse rods, with additional transverse rods to fill the gaps of the spirals, with sides.

The drawings show the structural features of the tape (figure 3 - figure 6, figure 9, figure 10).

Figure 9 and figure 10 respectively give a General plan of a wire conveyor belt and a view of the longitudinal edge of the belt with additional transverse rods to fill the gaps of the spirals, with sides.

By design solutions it differs from the main tape in that the tape is equipped with additional transverse rods for filling the gaps of each link of the tape closely (Fig.6, pos.2), preferably from a smooth wire. Filling the gaps of the spirals (links) with additional transverse rods, preferably made of smooth wire, eliminates the costly and time-consuming to manufacture, requiring special equipment for the manufacture of transverse plates.

4. A wire conveyor belt of double spirals of alternating left and right direction of weaving, with transverse rods from a wire of a bent profile in the longitudinal direction, with additional transverse rods to fill the gaps of the spirals, with sides.

The drawings show the structural features of the tape (Fig.3 - Fig.7, Fig.9, Fig. 10). The general plan of the conveyor belt and a view of the longitudinal edge of the belt with additional transverse rods to fill the gaps of the spirals, with sides similar to Fig. 9, Fig. 10, respectively.

By design solutions, the tape differs from the main tape in the execution of transverse rods from a wire of a bent profile in the longitudinal direction and filling the gaps of each link of the tape closely with additional transverse rods, preferably from a smooth wire.

The transverse rods of the wire bent profile in the longitudinal direction (Fig.7, pos.3) protect the coils of the spirals from displacement in the transverse direction. The turns of the spirals are connected with the transverse rods in the places of maximum bending of rounded, triangular, trapezoidal, etc. waves of rods.

To reduce the metal consumption of the tape and to obtain, accordingly, the economic effect with transverse rods of wire of a bent profile in the longitudinal direction, the step of winding the spirals is increased.

The gaps of the links are tightly filled with additional transverse rods, preferably made of smooth wire (Fig.6, pos.2), expensive and labor-intensive transverse plates are excluded.

When assembling a conveyor belt on a flyover, flat double spirals are laid across the longitudinal axis of the belt and parallel to each other, alternating spirals of the left (1l) and right (1p) weaving directions.

The spirals are connected by transverse rods (2, 3), inserting them into the joints of the spirals of the left and right direction of weaving. Summing up new double spirals of the left (1l) and right (1p) weaving direction and connecting them with transverse rods, form a web of wire conveyor belt (Fig. 1, Fig. 9).

As the section of the tape web is ready, the gaps of the spirals (tape links) are filled with transverse plates (4) or closely with additional transverse rods (2).

After installing the transverse rods and filling elements (transverse plates or additional transverse rods) along one longitudinal edge of the tape, the sides of the tape are formed in the form of a bend of the transverse rods (2, 3) and filling elements to the height of the side during their manufacture.

On the second longitudinal edge of the tape, the sides are formed in the form of a bend of the second end of the transverse rods and filling elements during shaping of the longitudinal edge of the tape.

The extreme turns of the spirals are bent around the transverse rods without welding (figure 4) or with welding to the filling elements (figure 5).

When ready, the wire conveyor belt is wound onto a container to transport the belt to the installation site.

The wire conveyor belt is mounted on the drums and rollers of the conveyor, joined by transverse edges and closed by a transverse rod into an endless conveyor belt (continuous transport). When moving under load, the tape (Fig. 1, Fig. 9) bends in the articulated joints formed by spirals - 1 and rods - 2, 3. During operation, the tape moves rectilinearly, without changing geometric dimensions (without distortions, without narrowing the tape in the transverse direction ) due to the alternation of spirals of the left (1L) and right (1p) directions of weaving, the bending of the extreme turns of spirals around the transverse rods without welding or with welding to the filling elements, and also due to the bent shape in the longitudinal direction of the transverse rods. Increasing the step of winding spirals with transverse rods of a bent profile in the longitudinal direction, filling the gaps of spirals (links of the tape) with additional transverse rods provide an economic effect.

The rectilinear movement of the wire conveyor belt during its operation under load increases the strength data of the belt, its service life.

Double spirals of the belt increase its strength data, increase the load capacity of the belt, ensure the elasticity of the belt due to the increase in the articulation of the spirals with the transverse rods, its use for any diameter of the drums and conveyor rollers.

For transportation of small items and parts, materials of small fractions, the “transparency” of the wire conveyor belt is reduced to zero by filling the gaps of the spirals (belt links) with transverse plates (4) or additional transverse rods (2).

The laboriousness of manufacturing a wire conveyor belt due to the exclusion of ball welding is reduced.

The sides of the wire conveyor belt expand the operational capabilities of the belt, the area of its use, create conditions for increasing the volume of transported products, and expand the useful area of the belt web.

The vertical elements of the side of the tape prevent the descent of the extreme turns of the spirals during operation of the tape.
