Abstract

The invention relates to the field of lifting and transport machinery and increases the efficiency of the device by reducing the time it is installed on the rails of a mobile conveyor. For this purpose, a pair of guides (H) 9 is fixed on the frame 1 with the possibility of contact with the rails 15. From the receiving drum 4, H 9 have a counterweight 11. At the ends of the counterweight 11 parallel to H 9, the shoes (B) 14 are mounted. 9 from the side of the supply drum 5 are located at an angle to the horizontal plane passing through H 9. The device for changing the tape (L) is lowered into a special opening and the ends of H 9 are mounted on rails 15. The wheels 18 of the conveyor run into B 14, fastened the mouth of the rails. The other part is fastened with gami 16. GTri replacement L cuts the old L 19 and one end of it with rivets 20 is connected with the new L 8.

The invention relates to a lifting and transport machinery, namely, devices for replacing the belt on a shorter conveyor, mainly mobile, located at a certain depth in hard-to-reach places, and can be used to replace the belt on conveyors, for example, in agglomeration and other industries .

The aim of the invention is to increase the efficiency of the device by saving time for its installation on the rails of the mobile conveyor.

1 shows a device for replacing the belt on the conveyor, side view; figure 2 is the same, top view; on fig.Z - section aa in figure 1; figure 4 - node I in figure 1; figure 5 - the device at the time of installing it on the rails, a general view.

The device for replacing the belt on the conveyor consists of a frame 1, on which the axes 3 of the receiving 4 and the feeding 5 drums are mounted in the bearing supports 2. The axis 3 of the receiving drum 4 is coupled to the drive 7 via the coupling 6. A supply roll 9 is wound on the supply drum 5. The rails 9 fixed parallel to its longitudinal axis are mounted on the frame 1. A fork counterweight 11 is attached to the ends of the guides 9 on the side of the receiving drum 4 formed against the conveyor 10, the protrusions 12 of which contain the pads 14 hinged on the axes 13 13. The ends of the guides 9 are from the feed drum 5 at an acute angle it to the horizontal plane passing through the rail heads 15. The installation of the device will be most effective if the value of this angle is within. The device also contains screw rods 16 for fixing it to the supporting structure.

The device is mounted on rails as follows.

Using a lifting mechanism, such as a hoist, for example, the device is moored and lowered into a specially designated opening, the width L of which is slightly greater than the height h of the device and much smaller than its length a (figure 5). The ends of the guides 9 are mounted on the heads of the rails 15. Bleed the cable 17 and the device, rolling on the guides 9, takes a horizontal position, and the counterweight 11 with its

mass helps it. On the heads of the rails 15, the shoes and the shoes 14, as they are installed parallel to the guide 9. The conveyor 10 with its wheels 18 slides over the toes of the shoes 14, thereby fixing the front part of the device on the rails 15. The screw of the device 16 rotates to support structure.

Replacing the conveyor belt is carried out as follows.

The old tape 19 is cut — one end of it is riveted 20 with a new tape 8, and the other end with a mounting strap 21 is connected to the receiving drum 4. The drum 4, rotated by the actuator 7, winds the worn tape 19, and the new tape 8, taking off drum 5, takes the position of the old one. The resulting joint is vulcanized, and the worn tape 20 together with the drum 4 is removed. The wheels 18 of the conveyor belt 10 roll off the toe of the shoes 14, the screw rods 16 are disconnected, the device is moored again by the cable 17 and removed through the mounting device.

The device due to the installation of guides on it and means for fastening them significantly reduces the time for its installation, which significantly increases the efficiency of belt replacement on mobile conveyors.
