Description

Technical Field

[0001] This utility model relates to the technical field of belt misalignment switch fixing equipment, specifically to an adjustable belt conveyor belt misalignment switch bracket. Background Technology

[0002] To prevent conveyor belt misalignment and reduce the damage caused by it, protective devices to prevent belt misalignment need to be installed on both sides of the conveyor belt. During installation, it is essential to ensure that the vertical rollers on the misalignment switches are perpendicular to the conveyor belt. For shorter belt conveyors, a pair of misalignment switches is typically installed at both ends. For longer belt conveyors, in addition to a pair at each end, a pair of misalignment switches also needs to be installed every 50-100 meters along the normal conveyor body.

[0003] Because belt conveyors have transition sections, the head and tail sections typically use two sets of 10° or 20° transition idler sets, while the normal conveyor body section generally uses 35° trough idler sets. With variations in transport routes and materials, belt conveyors now also use 45°–90° trough idler sets. Since the vertical rollers of the belt misalignment switch must be perpendicular to the conveyor belt during installation, different angles and heights of belt misalignment switch brackets are required depending on the trough angle.

[0004] Most current belt misalignment switch mounting brackets are fixed in angle and height, making them non-adjustable. During installation, the bracket column is often far from the conveyor frame, requiring additional connecting plates for welding. These limitations—the inability to adjust the angle, height, and overall position of the belt misalignment switch brackets—pose significant challenges to the fabrication and installation of belt misalignment switch brackets on belt conveyors.

[0005] In the prior art, to adjust the height and angle of the aforementioned misalignment switch, there is a patent application document with publication number CN208848777U, entitled "An Adjustable Multi-directional Misalignment Switch Mounting Bracket." This document describes a method where multiple fixing slots are provided on a third support plate to adjust the height of the misalignment switch, and an adjustment slot is provided on a first support plate to adjust the angle of the misalignment switch. After adjustment, the switch is fixed using corresponding fixing bolts. However, in practice, the misalignment switch is fixed by the compression of the support plate by bolt fasteners. Since trough conveyor belts generate frequent vibrations when transporting materials, especially during underground operations where the impact force of coal is significant, fixing it solely through friction is insufficient to maintain long-term stability. Therefore, the aforementioned patent is prone to loosening during use, affecting its performance. Utility Model Content

[0006] To overcome the above-mentioned defects, the purpose of this utility model is to provide an adjustable belt conveyor belt misalignment switch bracket, which uses an end face toothed disc to fix the upper and lower brackets, improve the angle adjustment range, and ensure the stability after connection.

[0007] To achieve the above objectives, this utility model provides an adjustable belt conveyor belt misalignment switch bracket, characterized in that it includes a belt frame, a support frame, and a misalignment switch body; the support frame is fixedly connected to the belt frame by threaded fasteners; an angle adjustment device is provided between the misalignment switch body and the support frame; the angle adjustment device includes an upper bracket and a lower bracket, and the misalignment switch body is fixedly connected to the upper bracket; the mating surfaces of the upper bracket and the lower bracket are respectively fixed with matching end face gears, the upper bracket and the lower bracket are hinged, and a clamping bolt for fixing the two end face gears is also provided at the axis of the end face gear.

[0008] Preferably, the support frame is connected to the tape bracket via a U-nut.

[0009] Preferably, the support frame is provided with a plurality of height adjustment holes, and the spacing between the plurality of height adjustment holes is adapted to the span distance of the U-shaped nut.

[0010] Preferably, the misalignment switch body and the upper bracket are fixedly connected by an adjustment plate, the lower end of the adjustment plate is fixedly connected to the upper bracket, and the adjustment plate is provided with adjustment holes for adjusting the position of the misalignment switch body.

[0011] The beneficial technical effects achieved by this utility model after adopting the above technical solution are as follows:

[0012] 1. Due to the installation of an angle adjustment device, which includes an upper bracket and a lower bracket, the body of the deviation switch is fixedly connected to the upper bracket; the mating surfaces of the upper bracket and the lower bracket are respectively fixed with matching end face gears, the upper bracket and the lower bracket are hinged, and the axis of the end face gears is also provided with clamping bolts for fixing the two end face gears. Utilizing the stable meshing characteristics of the gears, after fixing, even if subjected to frequent vibrations, the two gears will not loosen. Therefore, after fixing, the stability is stronger and the angle retention effect is better.

[0013] 2. Because it uses end face teeth as the angle adjustment device and clamping bolts as the rotation axis, the angle between the upper and lower supports can be refined more finely, and almost any angle can be adjusted. Especially when working underground, even if the lighting is not good, the angle can still be adjusted and it can be quickly fixed. Since the clamping bolts do not need to be removed during adjustment, the loss of parts can also be avoided.

[0014] 3. Because multiple height adjustment holes matching U-nuts are set on the support frame, the height of the idler roller group can be effectively adjusted. By utilizing the characteristics of U-bolts, the vertical height can be fixed while also effectively clamping, thus making the stability stronger.

[0015] 4. The addition of an adjustment plate below the belt misalignment switch body, used to adjust the distance L between the top of the belt misalignment switch body and the conveyor belt, further improves the practicality of the equipment. Attached Figure Description

An angle adjustment device 2 is provided between the misalignment switch body 1 and the support frame 3. The angle adjustment device 2 includes an upper bracket 21 and a lower bracket 22, and the misalignment switch body 1 is fixedly connected to the upper bracket 21. The mating surfaces of the upper bracket 21 and the lower bracket 22 are respectively fixed with matching end face gears 23. The upper bracket 21 and the lower bracket 22 are hinged, and the axis of the end face gears 23 is also provided with clamping bolts 24 for fixing the two end face gears 23. When loosened and loaded, the two end face gears 23 can rotate around the screw of the clamping bolt 24 at a certain angle. The support frame 3 for supporting the misalignment switch body 1 is fixedly connected to the belt 42 frame 4 by U-nuts 31. Generally, three idlers form an idler group 41, and a tape 42 is placed on the end face of the idler group 41. The tape 42 is used to transport materials.

[0027] In this invention, the angle adjustment device 2 is mainly used to adjust the angle θ shown in the figure. When it is necessary to adjust the angle of the deviation switch body 1, the clamping bolt 24 in the angle adjustment device 2 is loosened, and then the teeth of the two end face toothed discs 23 will separate. After rotating to the specified angle, the clamping bolt 24 is used to tighten the two end face toothed discs 23 to ensure that the angle between the upper bracket 21 and the lower bracket 22 does not change. There are two sets of end face toothed discs 23, which are fixedly connected to the upper bracket 21 and the lower bracket 22 respectively. Generally, they are directly welded to ensure stability.

[0028] The support frame 3 of this utility model is provided with a plurality of height adjustment holes 32, and the spacing between the plurality of height adjustment holes 32 is adapted to the span distance of the U-shaped nuts 31.

For easy connection, the spacing between adjacent height adjustment holes 32 should be consistent, and when the U-shaped nuts 31 are fixed, they should be able to just pass through two height adjustment holes 32. In the figure, the height adjustment holes 32 and the U-shaped nuts 31 are used to adjust the height distance to the height distance H of the support frame 3.

[0029] The misalignment switch body 1 and the upper bracket 21 of this utility model are fixedly connected by an adjusting plate 11. The lower end of the adjusting plate 11 is fixedly connected to the upper bracket 21. The adjusting plate 11 is provided with an adjusting hole 111 for adjusting the position of the misalignment switch body 1. The adjusting hole 111 on the adjusting plate 11 is generally elongated. After loosening the fixing bolt, it can be used to adjust the width L of the distance 42 of the tape shown in the figure.

[0030] Of course, there may be other embodiments of this utility model.
