Abstract

The invention provides an end part plug adjusting structure for a framework of a belt conveyor, which can ensure that no clearance exists between a wedge part of the plug and a mounting groove of the framework, further lead the wedge part of the plug to be in tight connection with the framework and have high strength, lead the wedge part of the plug to be difficult to fracture and ensure the normal safe working of the belt conveyor. The technical scheme is as follows: the end part plug adjusting structure comprises a roller and the framework, wherein the roller is mounted at the framework through the plug, the wedge part of the plug is inserted into the mounting groove of the framework, an inner concave hole is formed on the plug, a roller shaft of the roller is arranged in the inner concave hole, and the end part plug adjusting structure is characterized in that the inner concave hole is a long hole, the length of the inner concave hole is larger than that of the roller shaft, the width direction of the inner concave hole clamps the roller shaft, an inclined threaded hole which is far away from the framework is formed on the upper end surface of the plug, the inclined threaded hole leads to the inner concave hole, and the end part of an adjusting screw is top mounted at the roller shaft after the adjusting screw penetrates the inner concave hole.

Description

The end plug of band conveyor framework is adjusted structure

Technical field

The present invention relates to the physical construction technical field of band conveyor, the end plug that is specially the band conveyor framework is adjusted structure.

Background technology

Respectively there is a cylinder at the two ends of band conveyor, and as the supporter that returns of belt, its two end supports also is the degree of tension that is used to adjust the right and left on the plug of machine frame simultaneously, also prevents the structure of belt deviation.

The end plug of existing band conveyor framework is adjusted structure and is seen Fig. 1, Fig. 2, the drum shaft 2 of cylinder 1 is fixed in the indent circular hole 4 of both sides plug 3, the wedge portion 5 of plug 2 inserts in the mounting groove 7 of framework 6, plus-minus screw 8 is installed on plug 2, and plus-minus screw 8 one ends push up the plane of the frame 6 that frames up, when needing to adjust cylinder 1, by the plus-minus screw 8 on the rotation plug 3, plus-minus screw 8 withstands the end face of framework 6, and counteraction is left framework 6 to plug 3 tops, and cylinder 1 also and then moves like this.

The shortcoming of this structure is as follows: plug cooperates with framework by wedge portion, its end face separately is close-fitting, in case after adjusting, the wedge portion of plug and the mounting groove of framework just produce the gap, and plug more outward, the easy more fracture of plug wedge portion, easily the normal operation to band conveyor causes potential safety hazard.

Summary of the invention

At the problems referred to above, the end plug that the invention provides the band conveyor framework is adjusted structure, it can guarantee that the wedge portion of plug and the mounting groove of framework do not produce the gap, and then make the wedge portion of plug and the leak-tight joint and the intensity of framework, the wedge portion of plug is easy fracture not, guarantees the normal trouble free service of band conveyor.

The end plug of band conveyor framework is adjusted structure, its technical scheme is such: it comprises cylinder, framework, described cylinder is installed on described framework by plug, the wedge portion of described plug inserts in the mounting groove of described framework, described plug has inward recess, the drum shaft of described cylinder is loaded in the described inward recess, it is characterized in that: described inward recess is a slotted hole, the length of described inward recess is greater than the length of described drum shaft, the Width of described inward recess blocks described drum shaft, the upper surface of described plug has the leaning thread hole away from framework, described inward recess is led in described leaning thread hole, after plus-minus screw ran through described inward recess, its end was mounted on described drum shaft.

After adopting said structure of the present invention, when needing to adjust the position of cylinder, rotate plus-minus screw, can adjust the position of cylinder, the position of its plug is motionless, so it can guarantee that the wedge portion of plug and the mounting groove of framework do not produce the gap, and then makes the wedge portion of plug and the leak-tight joint and the intensity of framework, the wedge portion of plug is easy fracture not, guarantees the normal trouble free service of band conveyor.

The specific embodiment

See Fig. 3, Fig. 4, it comprises cylinder 1, framework 2, cylinder 1 is installed on framework 2 by plug 3, the wedge portion 4 of plug 3 inserts in the mounting groove 5 of framework 2, plug 3 has inward recess 6, drum shaft 7 is loaded in the inward recess 6, inward recess 6 is a slotted hole, the length of inward recess 6 is greater than the length of drum shaft 7, the Width of inward recess 6 blocks drum shaft 7, and the outer face of plug 3 has the leaning thread hole 8 away from framework, and inward recess 6 is led in leaning thread hole 8, after plus-minus screw 9 ran through inward recess 6, its end was mounted on drum shaft 7.

Claims

1. the end plug of band conveyor framework is adjusted structure, it comprises cylinder, framework, described cylinder is installed on described framework by plug, the wedge portion of described plug inserts in the mounting groove of described framework, described plug has inward recess, the drum shaft of described cylinder is loaded in the described inward recess, it is characterized in that: described inward recess is a slotted hole, the length of described inward recess is greater than the length of described drum shaft, the Width of described inward recess blocks described drum shaft, and the upper surface of described plug has the leaning thread hole away from framework, and described inward recess is led in described leaning thread hole, after plus-minus screw ran through described inward recess, its end was mounted on described drum shaft.
