Description

Technical Field

[0001] The utility model relates to the technical field of matching components for belt conveyors, in particular to a vertical roller adjustable self-aligning roller group. Background Art

[0002] Belt conveyor equipment has the characteristics of large conveying capacity, long conveying line and complex conveying line. In order to ensure that the conveyor belt can run stably and smoothly, it needs to be supported by the self-aligning roller group. At the same time, the self-aligning roller group can also effectively correct the deviation of the conveyor belt during its travel. The self-aligning roller group will bear a large impact force when in use, but the current self-aligning roller group is only assembled by rotating the bottom shaft and the fixed parts during installation. The support strength is low and the impact resistance is weak, requiring irregular operation and maintenance protection. The conveyor belt is actually allowed to have a certain amount of offset when it is traveling to reduce its friction during travel, but the installation position of the vertical rollers on the currently used self-aligning roller group is relatively fixed, and the tolerance for the deviation of the conveyor belt is relatively fixed, making its use inflexible.

DETAILED DESCRIPTION

[0017] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, the vertical roller adjustable self-aligning roller group includes a lower crossbeam 1, an upper crossbeam 2 is arranged opposite to the lower crossbeam 1, a roller frame is fixedly installed on the upper crossbeam 2, a horizontally arranged bottom roller 3 is installed and supported on the roller frame, and side rollers 4 are arranged oppositely and inclined on both sides of the bottom roller 3. The roller frame includes two roller stand frames 5 fixed on the upper crossbeam 2, and roller inclined frames 6 are arranged on the outer sides of the roller stand frames 5 respectively. The bottom roller 3 is horizontally and rotatably installed between the two roller stand frames 5, and the side rollers 4 are inclined and rotatably installed between the roller stand frames 5 and the corresponding roller inclined frames 6, and the conveyor belt is arranged on the top surface of the bottom roller 3 and the two side rollers 4. A reinforcing support beam 7 is fixedly connected between the upper crossbeam 2 and the roller frame. Specifically, the reinforcing support beam 7 is connected between the corresponding roller inclined frame 6 and the upper cross beam 2 to improve the firmness of the installation of the roller inclined frame 6, so that the installation support of the side roller 4 is more firm.

[0019] In this embodiment, a centering shaft seat is fixedly installed through the lower cross beam 1, and a centering shaft 8 is rotatably installed through the centering shaft seat, and the lower end of the centering shaft 8 is threadedly connected with an adjusting nut 9. The distance between the lower cross beam 1 and the upper cross beam 2 can be fine-tuned by the adjusting nut 9 to ensure that the centering shaft 8 rotates smoothly. The upper end of the centering shaft 8 is fixedly connected to the upper cross beam 2, and at least one reinforcing fixing plate is provided around the centering shaft 8, and the contact area with the centering shaft 8 can be increased by the reinforcing fixing plate to improve the connection strength between it and the upper cross beam 2.

At least two tapered roller bearings 11 are installed in the limiting clamp between the self-aligning shaft 8 and the self-aligning sleeve 10. A rotating shaft lip skeleton seal 12 is provided on the outer side of the tapered roller bearing 11 close to the upper cross beam 2. A deep groove ball bearing can also be arranged between the two tapered roller bearings 11 to strengthen the support for the self-aligning shaft 8. The tapered roller bearing 11 can withstand large radial loads and axial loads and has strong impact resistance. The adjusting nut 9 can make the self-aligning shaft 8 have a reasonable axial clearance, so that it can rotate flexibly and can also stably withstand large loads, making the operation of the conveyor belt safer and more reliable and having a longer service life.

[0021] The two ends of the self-aligning sleeve 10 are respectively detachably mounted with sleeve cover plates 13 by means of fixing bolts, which cooperate with the rotating shaft lip-shaped skeleton seal 12 to achieve partial encapsulation of the self-aligning shaft 8 and encapsulation of the tapered roller bearing 11, which can effectively prevent water and dust, reduce the friction between the self-aligning shaft 8 and the tapered roller bearing 11, and thus increase the service life of both.

[0022] A deflection correction roller seat is relatively installed on the roller frame, and an adjustment long hole 16 is provided through the deflection correction roller seat. A deflection correction vertical roller device is movably assembled with the adjustment long hole 16. The deflection correction vertical roller device is adjustable through the cooperation of the adjustment long hole 16 and the deflection correction roller seat.

[0023] Specifically, the deflection correction roller seat includes a deflection correction connecting plate 14 fixedly welded to the outer side of the roller frame, and a deflection correction fixing plate 15 is fixedly connected to one end of the deflection correction connecting plate 14 away from the roller frame, wherein the deflection correction connecting plate 14 plays a role in adjusting the installation space of the deflection correction vertical roller device. The adjustment long hole 16 is set through the deflection correction fixing plate 15, and at least two adjustment long holes 16 are set to improve the firmness of the installation of the deflection correction vertical roller device.

[0024] The deflection correction vertical roller device includes a vertical roller support seat 18 mounted on the deflection correction fixing plate 15 through a bolt assembly 17 and each of the adjustment long holes 16, and a deflection correction vertical roller 19 is rotatably mounted on the vertical roller support seat 18. The bolt assembly 17 includes a bolt and a nut used in conjunction, and the bolt assembly 17 can be adjusted in position within the adjustment long hole 16, so that the position of the deflection correction vertical roller 19 is adjustable, and the deviation amount of the conveyor belt can be adjusted according to its actual working condition, which has higher flexibility in use and can better prevent the jump-out damage caused by serious deviation of the conveyor belt.
