Description

Technical Field

[0001] This utility model relates to an auxiliary device for replacing idler rollers of a belt conveyor. Background Technology

[0002] Replacing trough idlers on conveyor belts in coal conveying systems is a significant undertaking. For belt idlers with a belt width of 1000mm or more, the weight is no less than 15KG. Daily replacement of idlers mainly relies on multiple people using methods such as prying and lifting the belt, which is labor-intensive and unsafe. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned problems and provide an auxiliary device for replacing conveyor belt rollers.

[0004] The above objectives are achieved through the following scheme: An auxiliary device for changing idler rollers of a belt conveyor includes a clamping frame, on which a left pulley group and a right pulley group are fixed. A rope winding drive device is fixed to one side of the clamping frame. A left hanging rope and a right hanging rope are wound on the rope winding drive device. The left hanging rope passes around the left pulley group and is fixed with a left hook. The right hanging rope passes around the left pulley group and the right pulley group and is fixed with a right hook. The left hook and the right hook are hung at both ends of the lifting roller.

[0005] The belt conveyor idler replacement auxiliary device includes a rope winding drive device comprising a support frame, in which a worm gear and a worm are connected via bearings, the worm meshing with the worm gear, and a rope hanging wheel fixed on the worm gear shaft.

[0006] The aforementioned auxiliary device for replacing idler rollers of a belt conveyor includes a cylindrical roller as the lifting roller.

[0007] The belt conveyor idler replacement auxiliary device includes a clamping frame comprising two L-shaped support plates. The tops of the two L-shaped support plates are fixed by a top plate, and a clamping frame is fixed to the bottom of each L-shaped support plate. Bolts are threadedly connected to the upper surface and side surface of the clamping frame. Beneficial effects

[0008] 1. This utility model eliminates the need for multiple people to pry or lift the idler rollers. The belt can be lifted using a roller lifting and rope winding drive device, reducing manpower input and physical exertion of manual operation.

[0009] 2. This utility model can be erected on the belt conveyor frame, and the support frame is clamped on the frame. The angle can be adjusted by the leveling bolts and clamped by the clamping bolts. It can be applied to the inclined section of the belt conveyor. Attached Figure Description

[0011] Reference Figures 1-5 An auxiliary device for changing idler rollers of a belt conveyor is disclosed. The device comprises a clamping frame, on which a left pulley group 10 and a right pulley group 15 are fixed. The left and right pulley groups have identical structures, each including a wheel frame 17, which is a U-shaped frame. Three axles are fixed inside the wheel frame, and each axle is rotatably connected to a pulley 18. A rope-winding drive device is fixed to one side of the clamping frame. A left hanging rope 9 and a right hanging rope 14 are wound onto the rope-winding drive device. The left hanging rope passes over the second pulley from the left to the right of the left pulley group and is fixed with a left hook 8. The right hanging rope passes over the second pulleys of both the left and right pulley groups and is fixed with a right hook 24. The left and right hooks are attached to both ends of a lifting roller 19.

[0012] The rope winding drive device includes a support frame 4, in which a worm gear 5 and a worm 2 are connected by bearings. The worm 2 meshes with the worm gear. A rope-hanging wheel 3 is fixed on the worm gear shaft 23 of the worm gear. A rocker arm 1 is fixed to the end of the worm for manual operation.

[0013] The lifting roller is a cylindrical roller.

[0014] The clamping frame includes two L-shaped support plates 6. The tops of the two L-shaped support plates are fixed by a top plate 11. A clamping frame 12 is fixed to the bottom of each L-shaped support plate. Bolts are threaded to the upper surface and side surface of the clamping frame. Two leveling bolts 13 are threaded to the upper surface of the clamping frame, and two clamping bolts 16 are threaded to the side surface of the clamping frame.

[0015] Working principle: First, lift the device above the coal conveyor belt. When replacing the idlers on the horizontal section of the conveyor belt, place the clamping frame on the frame, then tighten the leveling bolts and clamping bolts to secure the device. Then, pass the lifting roller under the belt, hook the left hook on the left side of the lifting roller, and the right hook on the right side. Crank the crank, and the worm gear meshes with the worm wheel, driving the rope wheel to rotate. The rope wheel has two grooves; one groove winds the left rope, and the other winds the right rope. The rotation of the rope wheel winds the left and right ropes simultaneously, pulling the lifting roller upward and lifting the belt, thus safely and conveniently completing the idler replacement. When replacing the idlers on the inclined section, fasten the clamping frame to the frame, adjust the two leveling bolts to make the device level, then tighten the clamping bolts before replacing the idler.
