Description

[Detailed Description of the Invention] The present invention relates to a carrier stand that supports a carrier roller of a belt conveyor.

The carrier stand currently in general use is
As shown in the figure, on a base 1', a number of sets of support columns 2', two each long and two short, are arranged in the direction in which the belt travels. The support column 2' is integrally connected to the base 1' by welding or bolting (see FIG. 2). The carrier roller 3', which is pivotally supported at both ends by such a support, may be damaged as the bearings at both ends are used and need to be replaced. belt 4'
However, this was often inefficient and dangerous. Furthermore, at the base end of the belt 4', cover plates 5' called skirts are often provided on both sides of the belt to prevent the transported objects loaded on the belt from falling out of the belt. At such locations, even if an attempt is made to lift the belt 4', the belt 4' cannot be lifted, making it even more difficult to replace the carrier roller 3'.

The present invention aims to provide a carrier stand that solves the above-mentioned problems.The gist of the invention is to install a shaft with a circular cross section in a horizontal cylindrical body on which a required number of columns for pivotally supporting the carrier roller are vertically installed. inserted loosely so that both ends protrude from both ends of the cylindrical body,
In addition, the outer diameter of both ends of the shaft is reduced by a certain length to form a polygonal cross section, and the shaft is connected to the shaft by bearings connected to bases placed on both sides at a required distance. The shaft is pivotally supported at both ends thereof so as not to rotate, and the shaft is always urged toward one end by a spring disposed between a spring stopper provided at one end of the shaft and the bearing, and the shaft is A stopper protruding from the side wall is inserted into a stopper penetration hole formed in the peripheral wall of the cylindrical body, and the stopper penetration hole is large enough to allow the stopper to penetrate near one end of the shaft. The shaft cannot move in the circumferential direction, but the other end of the shaft has a width that allows it to move in the circumferential direction, and the other end of the shaft has a shape that resists the force of the spring. This is a support stand for the carrier roller of a belt conveyor, characterized in that a pull-out lever is attached for pulling out the belt conveyor.

The present invention will now be described in detail with reference to the drawings. As shown in FIG. 3, a support column 2 for supporting a carrier roller 1 is vertically mounted on a horizontal cylindrical body 3.
A shaft 4 is loosely inserted into the cylinder, and the shaft has a diameter reduced by cutting off a certain length of the outside at both ends to make its cross section polygonal (usually rectangular), while the remaining central portion has a circular cross section. The shaft is journaled at both ends of its polygonal cross section by bearings 6 on a base 5. In this state, the shaft 4 cannot rotate, but the cylindrical body 3 on the shaft's outer periphery can freely rotate around the shaft. The shaft journaled in this way is constantly biased toward one end by a spring 8 disposed between the bearing 6 and a flange-shaped body or other spring stopper 7, while the shaft 4 is journaled at both ends by a spring 8 disposed between the bearing 6 and the flange-shaped body or other spring stopper 7.
A pull-out lever 9 is attached to the other end of the shaft to move the shaft to the other end only when necessary. Furthermore, as shown in Fig. 4, a stopper insertion hole 11 is provided at a required location on the peripheral wall of the cylinder, which is narrow at one end of the shaft (cylinder) and wide in the circumferential direction at the other end, so that when a stopper 10 protruding from the shaft is inserted, the shaft can move in the circumferential direction only at the other end of the shaft. Although one set of stoppers 10 and stopper insertion holes 11 may be provided, usually two sets are provided at an appropriate interval as shown in Figs. 3 and 4.

In the present invention constructed as described above, two sets are provided at an appropriate interval as shown in the conventional figure.

In the present invention constructed as described above, the cylindrical body 3 is positioned so that in a normal state, the support 2 supporting the carrier roller 1 stands straight as shown in FIG. In other words, shaft 4
A stopper 10 protruding from the stopper 10 is inserted into the stopper penetration hole 11 near the one end of the shaft and fixed at that position by the biasing force of the spring 8.
Since both ends of the shaft 4 are supported by bearings 6 so as not to rotate, the cylindrical body 3 cannot rotate and remains in the state shown in FIG. 3.

Next, if it becomes necessary to repair or replace the carrier roller, use the pull-out lever 9 to move the shaft 4 to the other end of the shaft (left side in Figures 3 and 4).
When the stopper 10 protruding from the shaft is also moved, the stopper penetration hole 1 is moved at the same time.
It is located near the other end of the shaft in 1. When the stopper 10 is in this position, as shown in FIG. 4, the stopper penetration hole 11 is widened in the circumferential direction, so that the cylindrical body 3 can freely rotate in the circumferential direction. Therefore, if the support column 2 is tilted in the circumferential direction by holding the support column 2 at an appropriate position, the support column 2 will be tilted as shown by the broken line in FIG. In this case, it will be easier to work if a tilting handle 12 is attached to at least one of the columns 2 on both sides, and the tilting ratio of the column 2 will be determined by the width of the wide part of the stopper penetration hole 11. For example, in order to avoid applying a large force to
It is more preferable to provide a support stand for stopping the tilted column at an appropriate position as shown in FIG. As shown in FIG. 5, if the support 2 and the carrier roller 1 are tilted to a certain extent, a space will be created between them and the stretched belt, so that necessary work on the carrier roller can be easily performed. When this necessary work is completed, the cylindrical body is returned to its original position by performing the operations in the reverse order as shown above, and the cylinder is returned to its normal state as shown in FIG. 3.

The applicant of the present application compared the conventional system shown in Figures 1 and 2 with the system of the present invention in a workshop owned by the applicant, and found that the conventional system had only one carrier roller. Average with two people
While it took 18.7 minutes, the device of the present invention required one person to complete the same replacement work in an average of 6 minutes.

As described above, according to the present invention, the repair or replacement work of the carrier roller can be carried out safely and quickly by one worker without the need for work jigs such as crowbars or jacks. There is.
