Description

Technical Field

[0001] The utility model belongs to the technical field of belt conveyors, and particularly relates to a redirecting roller adjusting device for correcting conveyor belt deviation. Background Art

[0002] Belt conveyors are a very common type of material conveying and lifting transportation equipment in mining production and processing. The operating status of the conveyor is related to the efficiency and safety of the entire production operation. Belt deviation is a common mechanical failure during the operation of belt conveyors. The main reason is uneven force on both sides of the belt, resulting in inconsistent elongation of the belt under tension. Belt deviation correction is also one of the more routine operations in daily equipment maintenance.

[0003] At present, the belt deviation correction operation of the belt conveyor is achieved by adjusting the position and angle of the redirecting roller or the driving roller. Nowadays, the belt deviation correction of the belt conveyor is mostly achieved by electric adjustment or telescopic cylinder assisted adjustment. The entire adjustment mechanism has a complex structure and high cost and requires regular maintenance. Moreover, this type of automated deviation correction mechanism lacks an effective self-locking mechanism after adjusting the angle of the redirecting roller. It relies on the self-braking effect of the drive unit or the cooperation of external objects to achieve the positioning and maintenance of the roller. Its stability is insufficient, and it is difficult for the belt conveyor to maintain its state during long-term operation.

[0004] To this end, we propose a conveyor belt deviation correction device for a redirecting roller which has a simple structure, low cost, strong stability and is easy to use. Utility Model Content

[0009] Furthermore, a slot is provided at the bottom of the roller frame near the outside, a rotating shaft for installing the adjusting rod is fixed in the slot, and two vertical and parallel baffles are welded in the slot at both ends of the rotating shaft.

A reinforcing plate is welded on each side of the connection position between the locking rod and the sleeve, and the two ends of the sleeve are fitted with the baffles at both ends of the rotating shaft.

DETAILED DESCRIPTION

[0022] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the present invention will be briefly introduced below in conjunction with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structures of the drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0023] Example

[0024] In view of the problems of the existing belt conveyor deviation correction operating mechanism, which is difficult to maintain stability, has high cost and failure rate, we propose a conveyor belt deviation correction and redirection roller adjustment device based on manual operation, which is low cost, simple in structure, strong in stability and easy to use. The specific solution is as follows:

[0025] like Figure 1-2 As shown, this embodiment provides a redirecting roller adjustment device for correcting conveyor belt deviation, including a roller mounting beam 1, a roller frame 3 with rollers is installed on the roller mounting beam 1 through a load-bearing bearing 2, a deflection limit unit is provided between the bottom of the roller frame 3 and the roller mounting beam 1, an adjusting rod 7 is also rotatably installed at the bottom of the roller frame 3, and a positioning plate 6 that cooperates with the adjusting rod 7 is installed on the roller mounting beam 1 through bolts.

[0026] The design of the entire device has a simple structure, easy operation, and a cost far lower than the current electric adjustment and telescopic cylinder adjustment mechanisms. It is also easier to maintain. In addition, the device adopts a mechanical structure as a whole, with a low failure rate. It also has a built-in locking function, and does not require the use of external objects to fix the steering roller bracket. The adjusted angle of the steering roller can be maintained for a long time, and there is no need for on-site staff to make frequent adjustments, which can effectively reduce the labor intensity of the staff.

[0027] like Figure 3-4As shown, the deflection limit unit specifically includes a deflection positioning pile 4 and a deflection limit pile 5; wherein, the deflection positioning pile 4 is vertically fixed at the center line position of the bottom of the roller frame 3, there are two deflection limit piles 5, and the two deflection limit piles 5 are distributed on both sides of the deflection positioning pile 4 and fixed together with the roller mounting beam 1. The cooperation of the deflection positioning pile 4 and the deflection limit pile 5 mainly functions to limit the maximum forward and backward deflection angle of the roller frame 3, so as to avoid excessive rotation of the roller frame 3 during manual operation, causing the locking rod 702 to leave the range of the positioning plate 6.

[0028] In order to make the adjustment rod 7 cooperate with the roller frame 3 effectively and facilitate the staff to deflect the roller frame 3 by adjusting the rod 7, a slot 10 is opened at the bottom position near the outside of the roller frame 3, and a rotating shaft for installing the adjustment rod 7 is fixed in the slot 10, and two vertical and parallel baffles are welded at both ends of the rotating shaft in the slot 10. At the same time, the adjustment rod 7 is adaptively designed, specifically: the adjustment rod 7 specifically includes a sleeve 701 that is sleeved on the rotating shaft inside the slot 10, and a locking rod 702 that cooperates with the positioning plate 6 is welded at the outer middle position of the sleeve 701. In order to enhance the stability of the connection between the locking rod 702 and the sleeve 701, a reinforcing plate 704 is welded on both sides of the connection position between the locking rod 702 and the sleeve 701, and at the same time, the two ends of the sleeve 701 are in contact with the baffles at both ends of the rotating shaft, so as to improve the synchronization between the adjustment rod 7 and the roller frame 3 during operation, thereby improving the accuracy of the angle offset adjustment of the roller frame 3.

[0029] In order to facilitate the staff to operate the device, a handle 703 is welded to the middle of the locking rod 702 on the outside of the roller frame 3, and the handle 703 is designed to be bent downward.

[0030] like Figure 3-4As shown, in order to make the device achieve self-locking effect after adjusting the angle of the roller frame 3, a hanging ring 8 is welded at the middle of the locking rod 702 near the inner side of the roller frame 3 and the middle of the bottom of the roller frame 3, and a tension spring 9 is connected between the two hanging rings 8. At the same time, its positioning plate 6 also needs to be adaptively designed, specifically including an angle plate 601, and a locking tooth 603 that matches the locking rod 702 is opened at an equal distance on one side edge of the angle plate 601 near the locking rod 702, and side positioning plates 602 are vertically welded on both sides of the bottom of the positioning plate 6 to support the positioning plate 6. It plays the role of lateral movement limitation. During the implementation of the conveyor belt correction operation, the staff lifts the adjusting rod 7 through the handle 703, causing the adjusting rod 7 to rotate around the rotating axis, so that the bottom of the adjusting rod 7 is separated from the locking tooth 603. At this time, the tension spring 9 is deformed by the force, and the staff swings the adjusting rod 7 left and right to drive the roller frame 3 to deflect left and right. After reaching the appropriate angle, the staff only needs to clamp the bottom end of the adjusting rod 7 in the corresponding locking tooth 603, and the tension spring 9 continues to apply tension to the adjusting rod 7 to ensure that the adjusting rod 7 always maintains effective cooperation with the locking tooth 603.

[0031] In order to improve the accuracy of the angle adjustment of the roller frame 3, the outer edge of the angle plate 601 adopts an arc design and is concentric with the center of the load-bearing bearing 2. At the same time, a number 604 is engraved on the top of the angle plate 601 corresponding to the position of each lock tooth 603, which helps the staff to view the angle offset data more intuitively.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
