Description

Technical Field

[0001] The utility model relates to the technical field of deviation adjusting devices, in particular to a downward deviation adjusting device. Background Art

[0002] Belt conveyor is a machine that uses the stepless motion of belts to transport materials. It is a machine that continuously transports materials by friction drive. Belt conveyor has the advantages of long transportation distance, large transportation capacity, small working resistance, easy installation, low power consumption, and less wear. Belt conveyors are used to transport coal in mines. During the operation of belt conveyors, factors such as uneven dropping of goods on the belt, belt bonding error, and deviation in the center setting of the roller bracket may cause the conveyor belt to deviate. Since the conveyor belt has an upper and lower part, the deviation correction can be divided into upper deviation correction and lower deviation correction. Among them, the more commonly used is the lower deviation correction, that is, to adjust the deviation of the lower conveyor belt. The current deviation adjustment structure is not convenient for flexible adjustment, and cannot adapt to the deviation correction needs of conveyor belts of different widths. It reduces the scope of application of the device, and the disassembly and maintenance are not convenient enough. Utility Model Content

[0018] The first deflection adjustment assembly 3 includes a first mounting block 5, a first slider 4 and a first deflection adjustment wheel 7. The first slider 4 is mounted on the rear side of the first mounting block 5 and is threadedly connected to the locking screw 203. The first deflection adjustment wheel 7 is rotatably mounted above the front end of the first mounting block 5 via a first rotating shaft 6. The first rotating shaft 6 is vertically arranged on the first mounting block 5 and elastically mounted on the first mounting block 5. The first deflection adjustment wheel 7 is rotatably connected to the first rotating shaft 6. A sliding hole 401 is arranged below the first slider 4. A sliding rail 202 is installed in the sliding groove 201-2. The first slider 4 slides on the sliding rail 202.

[0019] A first mounting groove 501 is provided along the front end of the first mounting block 5, and a limiting hole 502 is provided at the top of the first mounting groove 501. The limiting hole 502 and the first mounting groove 501 are both rectangular structures. The width of the limiting hole 502 is smaller than the width of the first mounting groove 501, and the width of the limiting hole 502 corresponds to the diameter of the first rotating shaft 6. A limiting strip 8 is installed below the first rotating shaft 6. The limiting strip 8 is a rectangular structure, and the length of the limiting strip 8 corresponds to the width of the first mounting groove 501. A limiting block 9 is elastically installed in the first mounting groove 501, and the limiting block 9 abuts against the front end of the limiting strip 8.

[0021] When the first deflection adjustment wheel 7 needs to be replaced, it is only necessary to pull the first rotating shaft 6 to squeeze the top material part 901 of the limit block 9, squeeze the limit block 9 downward, drive the first rotating shaft 6 and the limit bar 8 to continue to slide in the direction away from the first installation groove 501, until the limit bar 8 is separated from the first installation groove 501, the first deflection adjustment wheel 7 can be disassembled. Similarly, when it is necessary to install it, the limit block 9 is also squeezed to slide in the direction of the inside of the first installation groove 501, until the limit block 9 is not in contact with the bottom of the limit bar 8, and the limit block 9 receives the reaction force of the compression spring 10 and bounces upward against the outside of the limit bar 8, so as to achieve the installation of the first rotating shaft 6. The second deflection adjustment component 11 has the same structure and working principle as the first deflection adjustment component 3, so it will not be repeated.
