Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyor machinery, in particular to a tool for quickly replacing an upward belt roller. Background Art

[0002] Belt conveyors are important tools for transporting raw materials and finished products, especially in metal smelting enterprises. Belt conveyors are indispensable equipment. Belt conveyors are mainly composed of motors, reducers, head and tail wheels, brackets, rollers, belts, etc. Belt conveyors generally operate continuously for 24 hours. The main vulnerable parts are rollers. With the large-scale equipment and the requirements for environmental protection, belt conveyors are now fully sealed.

[0003] When replacing the upward roller of the belt, the traditional replacement method is that multiple people use steel pipes to lift the belt, and then one person takes down the broken roller and installs a new roller. If the head and tail rollers are broken, because the belt is tight and the force is large, even multiple people cannot lift the belt, which takes a lot of time;

[0004] When the rollers of large belt conveyors and fully sealed belt conveyors need to be replaced, a hand chain hoist is hung on the belt corridor channel steel just above the rollers that need to be replaced, the belt is fixed with the hand chain hoist guide chain, and slowly lifted up to raise the belt. Then one person takes out the broken roller and installs a new one. After replacing it, the hand chain hoist is lowered and finally the hand chain hoist is removed.

[0005] However, the above replacement method has certain problems, such as it is easy to damage the sealing cover on the belt conveyor and the surface of the belt, and it becomes increasingly difficult to replace the upward roller of the belt, which requires a lot of time and manpower and material resources, and there are certain safety hazards;

[0006] Based on this, we improved the equipment within the factory to meet the needs of quickly replacing the belt's upward rollers. Utility Model Content

[0011] A connecting block is symmetrically arranged on the two side edges of the bottom surface of the square tube base, and a plurality of bolt holes Ⅰ are opened on the top surface of the connecting block and the two ends of the square tube base. The connecting block is detachably fixed to the bottom surface of the square tube base by bolt fasteners screwed into the bolt holes Ⅰ. A nesting groove that can be nested on the belt conveyor support beam is opened on the bottom surface of the connecting block, and a bolt hole Ⅱ is opened on one of the vertical side walls of the nesting groove. The connecting block is relatively fixed to the belt conveyor support beam by bolt fasteners screwed into the bolt holes Ⅱ.

[0012] Preferably, the jack is located in the middle of the top surface of the square tube base.

[0013] Preferably, the belt support plate comprises a horizontal portion and an inclined portion, the inclined portions are symmetrically arranged on both ends of the horizontal portion, and the angle between the inclined portion and the horizontal portion is an obtuse angle.

[0014] Preferably, there is a chamfer between the horizontal portion and the inclined portion.

[0015] Preferably, three bolt holes I are equidistantly arranged on the square tube base, and the three bolt holes I are arranged in sequence along the length direction of the square tube base.

[0016] Preferably, there is one bolt hole I on the connecting block.

[0017] Preferably, the bolt hole II is located on a vertical side wall of the nesting groove close to the bolt hole I.
