[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0026] The fixing device of the belt conveyor roller of the utility model embodiment is described below according to the accompanying drawings

[0027] like Figure 1 and Figure 2 As shown, the fixing device of the belt conveyor roller of the embodiment of the utility model includes a base 1 and an extension member 2.

[0028] The base 1 is connected to the frame 100 of the belt conveyor, and at least a portion of the base 1 abuts against the frame 100 of the belt conveyor to limit the base 1 from moving along the length direction of the frame 100 of the belt conveyor. The first end of the extension member 2 is connected to the base 1, and the second end of the extension member 2 extends in a direction away from the base 1. The extension member 2 abuts against the roller shaft 201 of the belt conveyor to limit the roller shaft 201 of the belt conveyor from moving along the length direction of the frame 100 of the belt conveyor.

[0029] like Figure 1 As shown, the base 1 is provided with a plurality of threaded holes, and the base 1 can be connected to the frame 100 by bolts. Figure 1 In the left and right direction, a baffle is provided on the frame 100 on the left side of the base 1, that is, the baffle is welded to the frame 100 by welding, so that the base 1 can be abutted against the baffle; or, a groove is provided on the frame 100, so that the base 1 can be arranged in the groove, thereby realizing the arrangement of the frame 100 and the base 1 abutting against each other.

[0030] The extension piece 2 extends in an upward direction, and the extension piece 2 can limit the movement of the roller shaft 201 of the belt conveyor in a direction from right to left, thereby hindering the movement of the belt conveyor roller on the path where the belt conveyor roller is pulled away, thereby realizing the fixing device of the belt conveyor roller of the embodiment of the utility model to prevent the occurrence of the roller pulling away phenomenon.

[0031] If necessary, Figure 1As shown, on the frame 100, fixing devices are arranged at both left and right ends of the roller shaft 201 adjacent to the belt conveyor. Depending on the installation position, the fixing device can be arranged at the ends of the left and right ends of the roller shaft 201, or at the gap between the belt conveyor bearing and the roller. In other words, the fixing device of the belt conveyor roller of the embodiment of the utility model can change the setting position of the fixing device according to different types of belt conveyors to avoid interference with the roller, belt, etc., and has wide applicability.

[0032] In other words, the fixing device of the belt conveyor roller in the embodiment of the utility model adopts a setting in which the base 1 and the frame 100 are offset against each other, thereby avoiding the occurrence of the pulling phenomenon caused by insufficient bolt strength, and also using the extension piece 2 to intercept the belt conveyor roller on the pulling path, further improving the safety of the fixing device of the belt conveyor roller in the embodiment of the utility model.

[0033] like Figure 1 As shown, in some embodiments, the extension member 2 includes a first extension section 21 and a second extension section 22, the first extension section 21 is connected between the second extension section 22 and the base 1, the second extension section 22 is located above the roller shaft 201 of the belt conveyor in the height direction of the frame 100, the base 1, the first extension section 21 and the second extension section 22 define a buffer zone 12, and the end of the roller shaft 201 of the belt conveyor is placed in the buffer zone 12.

[0034] It is understandable that the second extension member 2 located above the roller shaft 201 of the belt conveyor can hinder the tendency of the roller shaft 201 of the belt conveyor to move upward when being pulled away, thereby further improving the safety of the fixing device of the belt conveyor roller in the embodiment of the utility model.

[0035] Optionally, the first extending section 21 extends in a direction away from the base 1 , and the second extending section 22 extends in a direction away from the first extending section 21 .

[0036] Specifically, Figure 1 As shown, the first extension member 2 extends in the up-down direction, the second extension member 2 extends in the left-right direction, and the first extension member 2, the second extension member 2 and the base 1 form a buffer zone 12 with an opening toward the right side.

[0037] Preferably, the base 1, the first extension section 21 and the second extension section 22 are integrally formed. Optionally, the base 1, the first extension section 21 and the second extension section 22 can be integrally formed by casting.

[0038] In some other embodiments, the base 1 includes a protrusion 11, which is located on a side of the base 1 adjacent to the frame 100 of the belt conveyor, and the protrusion 11 is arranged to penetrate the frame 100 of the belt conveyor.

[0039] Specifically, Figure 2 As shown, the protrusion 11 is located on the lower surface of the base 1, and the protrusion 11 can be welded to the base 1 or integrally formed with the base 1 by casting. It can be understood that a plurality of grooves are provided at positions corresponding to the protrusions 11 on the frame 100, so that the protrusions 11 pass through the grooves, so that the fixing device of the belt conveyor roller of the embodiment of the utility model further increases the contact area between the base 1 and the frame 100, thereby further reducing the possibility of the roller being pulled away.

[0040] Preferably, there are multiple protrusions 11, and the multiple protrusions 11 are arranged at intervals along the extension direction of the base 1. Therefore, the frame 100 needs to be provided with multiple grooves corresponding to the multiple protrusions 11 to ensure the adaptation of the base 1 and the frame 100.

[0041] The belt conveyor of the utility model embodiment is described below according to the accompanying drawings.

[0042] like Figure 3 As shown, the belt conveyor of the embodiment of the utility model includes a frame 100, a belt, a roller assembly 200 and a fixing device, wherein the fixing device is a fixing device according to any one of the above embodiments, the roller assembly 200 is connected to the frame 100, the belt is wound around the roller assembly 200, and the fixing device is connected to the frame 100 and is arranged adjacent to the roller assembly 200.

[0043] In some embodiments, the frame 100 includes a mounting slot, and at least a portion of the base 1 is disposed in the mounting slot.

[0044] Specifically, Figure 3 As shown, the mounting groove is opened on the upper surface of the frame 100, a threaded hole is provided in the mounting groove, and a threaded hole penetrating the base 1 is opened on the base 1 in the up and down directions. The base 1 can be threadedly connected to the mounting groove by bolts or screws to prevent the base 1 from moving in the up and down directions.

[0045] It can be understood that although the base 1 of the belt conveyor in the embodiment of the utility model is connected to the frame 100 by bolt connection, due to the presence of the mounting groove, when the roller is pulled away, the mounting groove can hinder the movement of the base 1, thereby avoiding to a certain extent the occurrence of the roller pulling away due to rust of the bolts and reduced fastening strength.

[0046] Preferably, the ratio of the dimension of the mounting groove in the height direction of the rack 100 to the dimension of the base 1 in the height direction of the rack 100 is greater than or equal to 0.5 and less than or equal to 1.

[0047] Specifically, as shown in the figure, the dimension of the mounting groove in the height direction of the rack 100 is a, and the dimension of the base 1 in the height direction of the rack 100 is b, then 0.5≤a / b≤1.

[0048] That is to say, when the base 1 is at a certain depth in the installation groove, the effect of preventing the pulling-away phenomenon from occurring is better.

[0049] In some embodiments, the frame 100 further includes a through hole, and the protrusion 11 on the base 1 passes through the through hole. The base 1 is the base 1 in the fixing device of the belt conveyor roller according to the above embodiment.

[0050] Specifically, Figure 3 As shown, the through hole penetrates the frame 100 in the up-down direction, and the protrusion 11 of the base 1 can be inserted into the through hole, so that the contact surface between the base 1 and the frame 100 is further increased, so that the roller is more obstructed when being pulled, and the possibility of the roller being pulled away is further reduced.
