Abstract

(57) [Summary] [Purpose] To provide a cradle for a belt roller that can prevent roller wear and belt deviation due to displacement of the center position of the load, and can alleviate buffer drop of the load. [Structure] The spring 6 is attached to the pedestal 1 (1b) of the belt roller 3 (side roller 3b) in the belt conveyor 5, and the belt roller 3 (side roller 3b) is attached.
Allows you to change the support status of. Then, the inclination of the side roller 3b can be changed by following a change in the load state of the belt conveyor 5, for example, a change in the center position of the load from the center position of the belt 2 and the like. To be able to move to the center. Also, the impact value of the load falling on the belt roller should be mitigated.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pedestal for a belt roller in a belt conveyor.

[0002]

[Prior art]

 Conventionally, as a pedestal for this type of belt roller, that is, as a pedestal 23 for a side roller 21 and a horizontal roller 22 as shown in FIG. 3, both pedestals 23 are fixed to a conveyor pedestal 24. Is generally known.

[0003]

[Problems to be solved by this device]

 However, in the above-mentioned conventional cradle, the one supporting the side roller 21 is fixed to the conveyor frame 24, so that the belt is not biased when the center position of the load 26 is deviated. As a result, as shown in FIG. 4, the side roller 21 is worn, the belt is stopped, and mine falls.

Further, in the conventional pedestal in which the side roller supporting member is fixed, as shown in FIG. 3, the frequency of breakage of the side roller 21 is increased due to the energy dropped from the chute 27. The life of the side roller 21 will be shorter than that of the roller in other places.

It should be noted that, in detail, this side roller is more frequently damaged than the horizontal roller. As shown in FIG. 5, the horizontal roller is capable of handling the entire vertical load (falling impact force) of the load on the horizontal axis surface. Take it above. Therefore, the force propagates inside the roller.

On the other hand, the side roller also receives the entire vertical load (falling impact force) of the load on the horizontal axis surface. The horizontal axis surface of the side roller, as shown in FIG. The area becomes smaller (L> L ') than the slope contacting with. Therefore, the horizontal axis surface of the side roller per unit area receives a larger drop impact force than the horizontal roller.

This invention was devised in view of the above-mentioned circumstances, and its purpose is to return the load center position shift on the belt to the original state and prevent roller wear and belt deviation due to the center position shift. It is an object of the present invention to provide a pedestal for a belt roller that can prevent the load from falling from the chute onto the belt.

[0008]

[Means for Solving the Problems]

 According to this invention, a spring is attached to a pedestal for a belt roller (side roller) in a belt conveyor, which has been conventionally fixed, so that a supporting state of the belt roller can be changed.

The spring allows the inclination of the side roller to be changed by following a change in the load state of the belt conveyor, such as a change in the center position of the load from the center position of the belt. So that the cargo can be moved to the center of the belt.

In addition, the spring attached to the pedestal of the belt roller in this belt conveyor can reduce the impact value of the load falling on the belt roller from the chute.

As described above, according to the present invention, the spring is attached to the pedestal supporting the belt roller (side roller) in the belt conveyor, so that the impact force applied to the belt roller (side roller) is absorbed and alleviated. It is possible to prevent deviation of the belt and damage to the belt roller.

[0012]

【Example】

 The pedestal of the belt roller of the present invention will be described below with reference to the illustrated embodiment.

The pedestal 1 (see FIG. 1) supporting the belt roller 3 for moving the belt, the upper end of which is in contact with the lower surface of the conveyor belt 2, on the conveyor pedestal 4 is a horizontal roller 3 a of the belt conveyor 5. At the center of the belt width direction, the pedestal 1a supported on the conveyor frame 4 and the left and right ends of the horizontal roller 3a are inclined upward from the axial end of the horizontal roller 3a. Both ends of the roller shaft of the side roller 3b of the book consist of a cradle 1b supported on a conveyor rack 4.

A spring 6 capable of changing the supporting state of the side roller 3b is attached to the receiving base 1b supporting the two side rollers 3b.

Since the bearing state of the side roller 3b can be changed by the spring 6 when the load 8 is conveyed by the belt conveyor 5 having the pedestal 1 (1a, 1b) having such a configuration, When the state of the load changes, for example, when the center position of the load 8 deviates from the center position of the belt, the bearing state of the side roller 3b changes and the load can be moved to the center position of the belt. it can.

More specifically, as shown in FIG. 2, when the center of the load 8 on the belt conveyor 5 is displaced, the inclination of the side roller 3b is increased by the spring 6 of the pedestal 1b of the side roller 3b. The cargo will move toward the center of the belt.

That is, when the load shifts in the width direction and the spring of the side roller 3b is pressed, when the spring reaction force and the load pressure are equal, the side roller 3b has the same inclination, but the spring reaction force When the pressing force is exceeded, the inclination of the side roller 3b increases and the load returns to the center.

On the other hand, as shown in FIG. 1, when the load from the chute 7 falls onto the conveyor belt 2, the spring 6 can reduce the impact on the side roller 3b.

As described above, according to the cradle 1 (1a, 1b) of the present invention, the cradle 1 (1b) supporting the belt roller 3 (side roller 3b) in the belt conveyor 5 is mounted on the cradle 1 (1b). With the spring 6, the impact force applied to the belt roller 3 (side roller 3b) can be absorbed and relieved, and deviation of the belt and damage to the belt roller can be prevented.

[0020]

[Effect of device]

 According to this invention, by attaching the spring to the side surface of the pedestal of the belt roller, the inclination of the side roller can be changed when the center position of the load of the belt conveyor is deviated.

Therefore, the center position of the load on the belt approaches the center of the belt, and it is possible to prevent deviation of the belt and, as a secondary effect thereof, improve the belt operating rate, prevent wear of the side rollers, and prevent falling minerals. it can.

Further, by installing a pedestal with a spring on the side roller under the chute, the load drop energy from the chute can be absorbed, and the side roller can be prevented from being damaged. Furthermore, it is possible to prevent noise, simplify the carrier roller replacement, and prevent damage to the belt.
