Detailed Description
Referring to fig. 2 to 8, the lower belt straight carrier roller frame for the belt conveyor comprises a frame 10 of the belt conveyor and lower carrier rollers 20 of the belt conveyor, wherein the lower carrier rollers are straight carrier rollers, lower support frames 11 for respectively mounting the lower carrier rollers are arranged on two sides of the frame, a lower carrier roller frame 30 is arranged on the lower support frames, a plurality of carrier roller grooves 31 are formed in the lower carrier roller frame, and carrier roller shafts 21 at two ends of each lower carrier roller are embedded into the carrier roller grooves 31.
The lower roller frame is provided with an inserting handle 32 which is inserted into the lower supporting frame, and the direction of the lower roller frame extending out of the supporting frame is opposite to the running direction of the descending belt.
The lower support frame is a cylindrical support frame, and the inserting handle is a cylindrical inserting handle inserted into an inner hole of the lower support frame.
The lower carrier roller frame is provided with three carrier roller grooves 31 which are arranged at equal intervals.
The distance W between the lower support frames on the two sides of the rack is 1050mm, the width D of each carrier roller groove is 10mm, and the distance S between every two adjacent carrier roller grooves is 30mm.
The idler groove is a groove body with two sides in an open conical shape 33.
The first embodiment is as follows:
referring to fig. 1, an ascending belt 40 of a conventional coal mine belt conveyor is lifted into a groove shape by three upper support rollers 41, so that the ascending belt has a good material conveying function, a descending belt 42 is lifted into a V shape by two lower support rollers 43 (called as 'two-linked rollers') and can prevent the descending belt from deviating, the two lower support rollers are hung on lower support frames 11 on two sides of a frame by hooks 44, and the lower support frames are made of round steel tubes. The belt conveyor needs to be provided with a sweeper (not shown in the figure) for sweeping the downward belt, and a straight carrier roller needs to be arranged in front of the sweeper so as to flatten the downward belt and utilize the work of the sweeper. Therefore, a structure for conveniently and flexibly installing and adjusting the straight carrier roller is needed for the coal mine belt conveyor. The present embodiment adopts the following technical solutions.
Referring to fig. 2 to 8, a lower belt straight supporting roller frame of a belt conveyor comprises a frame 10 of the belt conveyor and a lower supporting roller 20 of the belt conveyor.
The frame 10 is a frame body made of section steel, upright posts 12 are arranged on two sides of the frame, lower support frames 11 are arranged on the upright posts and used for mounting lower support rollers, the direction of the lower support frames 11 extending out of the upright posts is opposite to the running direction of a descending belt, the two lower support frames are arranged at the same height, and the distance W between the two lower support frames is 1050mm.
The lower carrier roller 20 is a straight carrier roller, two ends of the lower carrier roller are provided with carrier roller shafts 21, the carrier roller shafts are relatively static carrier roller shafts, and the lower carrier roller is equivalent to the carrier roller shafts to rotate. In this embodiment, the diameter of the lower carrier roller shaft is 10mm.
The lower supporting frame 11 is provided with a lower carrier roller frame 30, the lower carrier roller frame is provided with three carrier roller grooves 31, the width D of each carrier roller groove is 10mm, the three carrier roller grooves are arranged at equal intervals corresponding to the diameter of the lower carrier roller shaft, and the interval S between every two adjacent carrier roller grooves is 30mm. The carrier roller groove is a groove body with two sides in an open taper shape 33, and the taper angle alpha is 10 degrees.
The lower roller frame is provided with an inserting handle 32, and the inserting handle 32 is a cylindrical inserting handle corresponding to an inner hole of the lower supporting frame. The insertion handle 32 is inserted into the inner bore of the lower support frame so that the lower idler frame extends out of the lower support frame in a direction opposite to the direction of travel of the lower belt so that the lower idler frame is stably retained on the lower support frame.
When the lower carrier roller 20 is installed, the frame upright 12 close to the sweeper is selected, and the insertion handles 32 of the two lower carrier roller frames 30 are respectively inserted into the inner holes of the two lower support frames 11. The carrier roller shafts 21 at the two ends of the lower carrier roller are respectively embedded into the carrier roller grooves 31 of the two lower carrier roller frames, and the straight lower carrier roller can lift the descending belt and flatten the descending belt. Since the belt after being flattened is likely to deviate during running, at this time, as shown in fig. 7 and 8, the position of the carrier roller shaft 21 inserted into the carrier roller groove 31 can be adjusted, as shown in fig. 7, the carrier roller shafts 21 at both ends are arranged at an interval of one carrier roller groove, and the axis of the lower carrier roller 20 can generate a deflection angle α 1 of about 1.7 °. As shown in fig. 8, by arranging the idler shafts 21 at both ends at a distance of two idler grooves, the axis of the lower idler 20 can be made to have a deflection angle α 2 of about 3.3 °. As does the adjustment of the reverse deflection. After the lower carrier roller 20 is arranged in a deflection mode, the belt deviation can be corrected, and the belt can stably run.
