Description

Technical Field

[0001] This utility model relates to the technical field of conveyor belt equipment, specifically to a static alignment groove type idler frame for conveyor belts. Background Technology

[0002] Belt conveyors are core equipment for conveying coal and mineral materials. With their advantages of large transport capacity and low operating resistance, they are widely used in many industries such as mining, power, and chemicals. However, belt misalignment is one of the most common faults in the operation of belt conveyors, causing many adverse effects on production, including belt wear, material spillage, and even safety accidents.

[0003] Existing conveyor belt idler brackets typically connect the idler brackets to the base with bolts. When the conveyor belt deviates due to material imbalance, equipment vibration, or other reasons, it is impossible to correct the deviation by adjusting the angle of the idler brackets. If forced adjustment is required, the bolts must be removed and reinstalled, which is cumbersome and makes it difficult to ensure the synchronization of the idler brackets on both sides, resulting in extremely poor application flexibility. Secondly, the existing idler frame structure is mainly fixed by bolts, which are prone to loosening after long-term use. Therefore, regular maintenance and repair are required, resulting in a large amount of maintenance work in the later stage. Utility Model Content

[0004] The first technical problem this utility model aims to solve is to provide a static adjustment groove type idler frame for a conveyor belt machine. Through the cooperation of the arc-shaped correction groove and the self-locking bolt, the static angle adjustment of the idler frame can be realized, thus solving the problem of the conveyor belt not being able to be corrected in time when it runs off track.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A static alignment groove type idler frame for a conveyor belt includes a base arranged longitudinally on the left and right sides, an idler bracket installed laterally between the left and right bases, and multiple positioning rollers fixed vertically above the idler bracket. The core invention is that: a correction seat is fixedly installed on the top of the base between the base and the roller bracket, and a horizontal arc-shaped correction groove is opened on the surface of the correction seat; wherein, the arc-shaped correction groove installed on the left side of the base and the arc-shaped correction groove installed on the right side of the base are at the same horizontal height and are concentrically arranged with each other. A positioning seat is also provided between the base and the roller bracket, and is fixedly installed below the roller bracket. The positioning seat has a screw hole, and a self-locking bolt is installed in the screw hole. The self-locking bolt passes through the arc-shaped correction groove and is assembled with the screw hole. The self-locking bolt can completely fix the correction seat and the positioning seat.

[0006] By adopting the above solution, the static alignment groove type idler frame of the conveyor belt can adjust the angle of the idler support horizontally along the groove without disassembling the bolts through the cooperation of the arc-shaped alignment groove and the self-locking bolt, thereby quickly correcting the belt deviation and improving the application flexibility; secondly, the arc-shaped alignment grooves on the left and right sides are concentric and at the same height, ensuring that the idler supports on both sides are adjusted synchronously, which makes the adjustment more convenient.

[0007] As a preferred embodiment of a static alignment groove type idler frame for a conveyor belt machine, the minimum width of the self-locking bolt cap is 1.5 times the width of the arc-shaped alignment groove to prevent the bolt from coming out of the alignment groove.

[0008] As a preferred embodiment of a static alignment groove type idler frame for a conveyor belt machine, the number of self-locking bolts and screw holes are equal, and the number of each is 1-3. The self-locking bolts can be flexibly selected according to actual needs, taking into account both fixing strength and adjustment convenience.

[0009] As a preferred embodiment of the static alignment groove type idler bracket for a conveyor belt machine, the maximum unidirectional alignment angle of the idler bracket along the arc-shaped alignment groove is 15°, which avoids excessive deformation of the idler bracket, ensures structural stability, and basically meets the daily adjustment of the alignment angle.

[0010] The second technical problem to be solved by this utility model is to provide a static alignment groove type idler frame for a conveyor belt. By adding a bolt anti-loosening mechanism to the self-locking bolt, the self-locking bolt cannot rotate in the loosening direction, which can effectively prevent the self-locking bolt from loosening and solve the problem of large maintenance workload in the later stage.

[0011] To achieve the above objectives, the present invention adopts the following technical solution: Based on the above scheme, the head of the self-locking bolt is also equipped with a bolt anti-loosening mechanism; the bolt anti-loosening mechanism includes a mounting component mounted on the head of the self-locking bolt, an adjusting component rotatably mounted on the right end of the mounting component, and an anti-loosening set screw threaded through the top of the adjusting component; wherein, the anti-loosening set screw tightly abuts against the edge of the positioning seat, so that the self-locking bolt cannot rotate in the loosening direction.

[0012] By adopting the above scheme, when installing the bolt anti-loosening mechanism, first assemble the installation component onto the tightened self-locking bolt cap, then rotate the adjusting component to make the adjusting component parallel to the edge of the positioning seat, and finally rotate the anti-loosening set screw to make the anti-loosening set screw tightly abut against the edge of the positioning seat. At this time, the self-locking bolt cannot rotate in the loosening direction, that is, the self-locking bolt cannot loosen.

[0013] As a preferred embodiment of a static alignment groove type idler frame for a conveyor belt machine, the bolt anti-loosening mechanism further includes a protrusion fixed to the upper end of the mounting component and a groove formed on the self-locking bolt head; wherein the protrusion and the groove are fitted by an interference fit; wherein the protrusion is a cross protrusion and the groove is a cross groove, the interference fit between the cross protrusion and the groove ensures that the mounting component and the bolt head are firmly connected and can prevent the anti-loosening mechanism from falling off.

[0014] As a preferred embodiment of a static alignment groove type idler frame for a conveyor belt machine, a throttle handle is coaxially fixed at the bottom end of the alignment component to facilitate rotation of the alignment component.

[0015] The beneficial effects of this utility model are: 1. Achieve static belt misalignment: Through the combination of the arc-shaped correction groove and the self-locking bolt, the angle of the idler bracket can be adjusted along the groove without disassembling the bolt, thereby quickly correcting belt misalignment and improving application flexibility; 2. Good synchronization: The arc-shaped correction grooves on the left and right sides are concentric and at the same height, ensuring that the roller supports on both sides are adjusted synchronously, which makes the adjustment more convenient; 3. Reliable Fixing: The width of the bolt head is greater than the width of the straightening groove to prevent the bolt from coming out; the anti-loosening mechanism prevents the bolt itself from loosening by abutting against the positioning seat with the set screw; the interference fit between the cross protrusion and the groove prevents the anti-loosening mechanism from falling off; 4. Easy to operate: The throttle design makes manual adjustment easier, and the number of 1-3 bolts ensures both strength and simplifies operation. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1, as Figure 1 As shown, a static alignment groove type idler frame for a conveyor belt includes a base 1 arranged longitudinally on the left and right sides, an idler bracket 2 installed laterally between the two bases 1, and four positioning rollers 3 vertically welded and fixed above the idler bracket 2.

[0020] like Figures 2 to 5As shown, a correction seat 4 is provided between the base 1 and the roller bracket 2 and is fixedly installed on the top of the base 1 by bolts and nuts. The surface of the correction seat 4 is provided with a horizontally arranged arc-shaped correction groove 5. The arc-shaped correction groove 5 installed on the left side of the base 1 and the arc-shaped correction groove 5 installed on the right side of the base 1 are at the same horizontal height and are concentrically arranged.

[0021] Continue as Figures 2 to 5 As shown, a positioning seat 6 is welded and fixedly installed below the roller bracket 2 between the base 1 and the roller bracket 2. The positioning seat 6 has a screw hole 7 and a self-locking bolt 8 is installed in the screw hole 7. The self-locking bolt 8 passes through the arc-shaped correction groove 5 and is assembled with the screw hole 7. The self-locking bolt 8 can completely fix the correction seat 4 and the positioning seat 6.

[0022] like Figure 3 As shown, the minimum width of the head of the self-locking bolt 8 is 1.5 times the width of the arc-shaped correction groove 5 to prevent the bolt from coming out of the correction groove.

[0023] Continue as Figure 3 As shown, the number of self-locking bolts 8 and screw holes 7 is equal, with one of each. The number of self-locking bolts 8 can be flexibly selected according to actual needs, taking into account both fixing strength and adjustment convenience.

[0024] like Figure 6 As shown, the maximum unidirectional adjustment angle of the roller bracket 2 along the arc-shaped correction groove 5 is 15°, which avoids excessive deformation of the roller bracket 2 and ensures structural stability. It basically meets the daily adjustment of the correction angle.

[0025] Working principle of Example 1: When belt misalignment is detected, loosen the anti-loosening screw 93 (rotate counterclockwise). At this time, the self-locking bolt 8 can slide along the arc-shaped correction groove 5; push the idler bracket 2 along the arc-shaped correction groove 5 to adjust it to the position for belt misalignment correction (maximum 15° adjustment in one direction); after correction adjustment, tighten the self-locking bolt 8. This static correction groove type idler bracket for the belt conveyor, through the cooperation of the arc-shaped correction groove 5 and the self-locking bolt 8, allows for horizontal adjustment of the idler bracket 2 along the groove without disassembling the bolt, thereby quickly correcting belt misalignment and improving application flexibility; secondly, the arc-shaped correction grooves 5 on both sides are concentric and at the same height, ensuring synchronous adjustment of the idler brackets 2 on both sides, making adjustment more convenient.

[0026] Example 2, as Figures 7 to 9 As shown, the only difference between this embodiment and Embodiment 1 is that, based on Embodiment 1, the number of self-locking bolts 8 and screw holes 7 is changed from 1 to 3, further improving the overall stability and reliability.

[0027] Example 3, as Figures 10 to 12As shown, the difference between this embodiment and Embodiment 1 is that, based on Embodiment 1, the head of the self-locking bolt 8 is also equipped with a bolt anti-loosening mechanism 9; the bolt anti-loosening mechanism 9 includes a mounting component 91 mounted on the head of the self-locking bolt 8, an adjusting component 92 rotatably mounted on the right end of the mounting component 91, and an anti-loosening set screw 93 threaded through the top of the adjusting component 92; wherein, the anti-loosening set screw 93 tightly abuts against the edge of the positioning seat 6, so that the self-locking bolt 8 cannot rotate in the loosening direction.

[0028] like Figures 12 to 13 As shown, the bolt anti-loosening mechanism 9 also includes a protrusion fixed to the upper end of the mounting component 91 and a groove opened on the head of the self-locking bolt 8; wherein the protrusion and the groove are fitted by an interference fit; wherein the protrusion is a cross protrusion 94 and the groove is a cross groove 95. The interference fit between the cross protrusion 94 and the groove ensures that the mounting component 91 is firmly connected to the bolt head and can prevent the anti-loosening mechanism from falling off.

[0029] like Figure 12 As shown, a throttle handle 96 is coaxially fixed at the bottom end of the directional adjustment component 92, which facilitates the rotation of the directional adjustment component 92.

[0030] The working principle of Example 3: When installing the bolt anti-loosening mechanism 9, first assemble the mounting component 91 onto the head of the tightened self-locking bolt 8, then rotate the adjusting component 92 so that the adjusting component 92 is parallel to the edge of the positioning seat 6, and finally rotate the anti-loosening set screw 93 so that the anti-loosening set screw 93 tightly abuts against the edge of the positioning seat 6. At this time, the self-locking bolt 8 cannot rotate in the loosening direction, that is, the self-locking bolt 8 cannot be loosened.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
