Description

The invention relates to a transport engineering, namely to belt conveyors used for transporting bulk material.

The purpose of the invention is to simplify the design.

The drawing shows a belt conveyor.

The belt conveyor contains a load-carrying tape 1, the envelope of the drive 2 and

tension 3 drums. The drum 2 is set to 10 resGs than the size of the b7r7b7n 8. flax on the shaft 4 connected to the drive (not the cable section located on the drawing board), and is made of two sections: non-drums 8-2-7, reduced,

drive 5 and drive 6. Section 5 installs the tension of the drum drum on the shaft 4 freely (with the possibility of g drawing). With this tape 1

rotation). Section 6 is installed. The section of the cable, located shaft 4 is stationary. Both sections are “drums 8-2-7,

no equal diameter. Section 6 penetrates cable slack

It reduces traction effort to tape 1, and sec--

10-15, causing only the rotation of the roller 16 around its axis 17. The tension drum 3 does not shift.

When the belt 1 is stretched, its tension decreases. The slippage of the tape along the drive drum (section 6 begins. Section 5 begins to rotate slower than section 6 (and shaft 4). A difference in the speeds of rotation of the drums 7 and 8 appears. As a result, the cable 9 is wound on the drum 7, speed 5 does not participate in the transmission traction force, but is in contact with the belt and moves with it. Coaxially with sections 5 and b, winch drums 7 and 8 are mounted on shaft 4. Drum 7 is rigidly connected to section 6 (fixedly mounted on shaft 4). The drum 8 is mounted on shaft 4 loosely and rigidly connected to

20

The spring loaded roller 22 is selected. This process occurs until the speeds of the drums 8 and 7 are equal, i.e., the slippage of the tape relative to the driving drum does not disappear.

The conveyor automatically provides the minimum necessary tension for the operation of the conveyor belt, with the horse-drive section 5. The diameters of the drum-25 structure of the tensioning device is simple.

New 7 and 8 are equal to each other. The replacement of rather complex nodes — ShesTros 9 is made closed, covers the differential gear and gears with several (two-three) rounds of gears from three brushes — attached 7 and 8 and slung over fixed ones winch drum and non-blocks 10-15. With a tension drum, 3 blocks with a roller. Simplification of the drag chain 9 is movably connected with the possibility of structure 30, which reduces the cost of making the movement relative to it. This connection and maintenance of the tensioning device, which is carried out by means of free rotation, increases the reliability of operation, reduces the spraying roller 16, the axis 17 of which is the consumption of spare parts, which is significantly increased by 18 with the bracket 19, which ensures the efficiency of the conveyor . The winch drums 7 and 8 of drum 3 are connected to the supports 20 and 21 of tension. In the drawing, the tension roller 22 and podrugi-35 are shown as separate units. However, the spring-bore 23, chooses the slack of the cable, it can be refused if it is wound and prevents its possible sagging. The cable 9 is directly on the projecting

When the conveyor is working, the drive rotates 1 of the sections 5 and 6 of the baravodal drum 2 under the belt. With a nominal mode of 2. 2. At the same time, it is necessary to provide 5 as a result of interaction with the lent, “pull on them the protective shoulders for the prevented 1” rotational speeds of shaft 4 and section 6. At the same time, the angular velocities of the winch drums 8 and 7 connected to sections 5 and 6 are also equal to each other. Since the drums 8 and 7 are inversions of a possible cable release from the sections. In addition, the cable 9 can be wound directly on the shaft 4, abandoning the drum 7, and instead of the drum 8 to apply the sleeve. At the same time, it is necessary to have the same diameter, then they must be surrounded by the condition of equality of external diurnal velocities. As a result, the cable is 9 meters of those elements that will be straightened on the drums 7 and 8 and block the functions of the drums 7 and 8.

The wrench is larger than the width of the cable section located on the lugs 10-15, causing only the rotation of the roller 16 around its axis 17. The tension drum 3 does not move.

When the belt 1 is stretched, its tension decreases. The slippage of the tape along the drive drum (section 6 begins. Section 5 begins to rotate slower than section 6 (and shaft 4). A difference in the speeds of rotation of the drums 7 and 8 appears. As a result, the cable 9 is wound on the drum 7 quickly

The spring loaded roller 22 is selected. This process occurs until the speeds of the drums 8 and 7 are equal, i.e., the slippage of the tape relative to the driving drum does not disappear.

The conveyor automatically provides the minimum necessary tension for the operation of the conveyor belt, while preventing the cable from coming off sections. In addition, the cable 9 can be wound directly on the shaft 4, abandoning the drum 7, and instead of the drum 8 to apply the sleeve. At the same time you need
