Description

Technical Field

[0001] This utility model belongs to the technical field of belt conveyors, specifically relating to a turning device for a belt conveyor. Background Technology

[0002] Belt conveyors are the main equipment for transporting various bulk materials in coal mines, both underground and on the surface. Traditional belt conveyors can only transport materials in a straight line. In mines with complex geological conditions, roadway bends frequently occur during tunneling or mining. When the transport line needs to change direction and turn, material transport can only be achieved by overlapping two conveyors. This results in problems such as more equipment, higher investment, more complex transport systems, more manual labor, and increased maintenance. Therefore, it is necessary to research and develop a turning device. Summary of the Invention

[0003] This utility model provides a turning device for a belt conveyor to solve the problems mentioned in the background art. The specific solution is as follows:

[0004] A turning device for a belt conveyor includes a frame. Two upper idler frames are arranged side by side on the top of the frame. V-shaped idler sets are respectively arranged on one side of the two upper idler frames, and two inclined idler frames are symmetrically arranged on the other side. Correction mounting frames are vertically arranged on both sides of the top of the frame. The two correction mounting frames are located on the frame between the two upper idler frames and are arranged crosswise. Correction idler sets are inclined on the two correction mounting frames. Upper pressure frames are respectively arranged on one side of the frame of the two correction mounting frames. The two upper pressure frames are arranged crosswise on the frame. Upper pressure rollers are respectively arranged on the two upper pressure frames facing the middle of the frame and inclined downward. Long connecting plates and short connecting plates are horizontally connected on both sides of one end of the frame.

[0005] Furthermore, the two sets of guiding rollers are respectively positioned towards the center of the frame and inclined upwards.

[0006] Furthermore, a first support frame is detachably connected to one side of the middle part of the frame by bolts, and a first support roller is horizontally arranged on the first support frame.

[0007] Furthermore, a vertical roller mounting frame is provided on one side of the frame of the first support frame, and a vertical roller is provided on the vertical roller mounting frame.

[0008] Furthermore, a second support frame is detachably connected to the frame on the opposite side of the first support frame by bolts. The second support frame is provided with a second support roller that is inclined toward the middle of the frame. The inclination angle of the second support roller is consistent with that of the support roller in the V-shaped support roller group on the same side.

[0009] Furthermore, the first support frame has several through holes vertically opened, the first support roller is mounted on the fixed plate, and the fixed plate is fixedly mounted on the first support frame by the first screw and the first adjusting nut.

[0010] Furthermore, pads are provided on both sides of the correction mounting frame, the correction roller assembly is mounted on a mounting plate, and a second screw is vertically provided on the side of the mounting plate away from the middle of the frame. The second screw passes through the two pads and is fixed to the correction mounting frame by the second adjusting nut.

[0011] The beneficial effects of this utility model are:

[0012] This utility model discloses a turning device for a belt conveyor. By setting a correction mounting frame and its correction roller group, an upper pressure frame and its upper pressure roller, a first belt support roller, and long and short connecting plates on both sides of the top of the frame, when the transport line needs to turn, the turning characteristics of the conveyor belt are achieved by connecting multiple sets of long and short connecting plates and by making the conveyor belt on the turning side wrap around the correction roller group to shorten the belt spacing. The upper pressure roller presses down on the upper side of the conveyor belt and the first belt support roller supports the lower side of the conveyor belt. This reduces the investment in equipment and the amount of maintenance work required by workers when the transport route turns, thereby improving the efficiency of the transport work.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] See Figure 1-5 A turning device for a belt conveyor includes a frame 1. Two upper idler frames 2 are arranged side-by-side on the top of the frame 1, with the idler frames 2 detachably connected to the top of the frame 1. V-shaped idler groups 3 are respectively arranged on one side of each of the two upper idler frames 2, and two inclined idler rollers 4 are symmetrically arranged on the other side. Both the V-shaped idler groups 3 and the inclined idler rollers 4 are positioned in the direction of the conveyor belt's running direction. Correction mounting frames 5 are vertically arranged on both sides of the top of the frame 1, with both correction mounting frames 5 located on the frame 1 between the two upper idler frames 2 and arranged crosswise. Correction idler groups 6 are inclinedly arranged on each of the two correction mounting frames 5. It consists of two parallel straightening rollers. On the frame 1 on one side of the two straightening mounting frames 5, there are upper pressure frames 7 respectively. The two upper pressure frames 7 are arranged crosswise on the frame 1. Each of the two upper pressure frames 7 has an upper pressure roller 8 facing the middle of the frame 1 and inclined downward. Multiple through holes are spaced apart along its height direction on the upper pressure frame 7. When it is necessary to adjust the height of the upper pressure roller 8, it can be achieved by installing the upper pressure roller 8 in different through holes. Long connecting plates 9 and short connecting plates 10 are horizontally connected on both sides of one end of the frame 1 respectively. The turning ability of the conveyor can be gradually realized through the long connecting plates 9 and short connecting plates 10 on both sides.

[0021] The preferred two sets of corrective rollers 6 are respectively oriented toward the middle of the frame 1 and inclined upwards.

[0022] A first belt support frame 11 is detachably connected to one side of the middle section of the preferred frame 1 by bolts. A first belt support roller 12 is horizontally provided on the first belt support frame 11. The first belt support roller 12 is used to support the lower end face of the upper conveyor belt, which can make the conveyor belt more stable during operation.

[0023] A vertical roller mounting frame is provided on one side of the frame 1 of the preferred first support frame 11, and a vertical roller 13 is provided on the vertical roller mounting frame, wherein the vertical roller 13 helps to prevent the conveyor belt from running off-center.

[0024] A second belt support frame is detachably connected to the frame 1 on the opposite side of the preferred first belt support frame 1 by bolts. The second belt support frame is provided with a second belt support roller (not shown in the figure) that is inclined toward the middle of the frame 1. The inclination angle of the second belt support roller is the same as that of the roller in the V-shaped roller group 3 on the same side. The second belt support roller is located on the lower end face of the upper conveyor belt. The setting of the second belt support roller effectively improves the stability of the conveyor belt during operation.

[0025] The preferred first belt support frame 11 has several vertically opened through holes, and the first belt support roller 12 is set on the fixed plate. The fixed plate is fixed on the first belt support frame 11 by the first screw and the first adjusting nut. The first screw can be fixed in different through holes by the first adjusting nut to adapt to the turning angle of the conveyor belt.

[0026] The preferred alignment mounting frame 5 has pads 14 on both sides, and the alignment roller group 6 is mounted on a mounting plate 15. The mounting plate 15 is vertically provided with a second screw 16 on the side away from the middle of the frame 1. The second screw 16 passes through the two pads 14 and is fixed to the alignment mounting frame 5 by the second adjusting nut 17. The height of the end of the alignment roller group 6 can be adjusted by adjusting the pads 14 on both sides, thereby satisfying the winding of the conveyor belt 6.

[0027] The working principle of this utility model is as follows: First, it should be noted that the frame of the turning belt conveyor is composed of several of these devices. When assembling the turning part, the long connecting plate 9 and the short connecting plate 10 are connected to the next device that is opposite to the long connecting plate 9 and the short connecting plate 10, and the turning frame can be obtained. When installing the conveyor belt, when the conveyor belt on the turning side passes the correction roller group 6, the conveyor belt will wrap around it. The number of correction roller groups 6 can be determined according to the actual turning angle. Then, by adjusting the height of the first support roller 12 and the second support roller, the lower end face of the upper conveyor belt is supported on both sides. Then, by adjusting the height of the upper pressure roller 8, the upper surface of the upper conveyor belt is pressed on both sides to make the operation stable.
