At least three people are needed for the whole process, and in the process of prying the belt with a crowbar, there is a safety hazard that the end of the crowbar is easy to slip off without a fixed point, which greatly passively causes the replacement of the supporting roller.

[0003] Therefore, the prior art needs to be further improved. CONTENT OF THE UTILITY MODEL

[0004] In view of the deficiencies of the prior art, a supporting roller replacement auxiliary device is provided to solve the problem of the safety hazard that the end of the crowbar is easy to slip off without a fixed point in the process of prying the belt with a crowbar in the prior art, which greatly passively causes the replacement of the supporting roller.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technology to achieve:

[0006] A supporting roller replacement auxiliary device, comprising a supporting assembly and a supporting assembly for supporting the supporting assembly, the supporting assembly and the supporting assembly are detachably connected, and the supporting assembly can rotate relative to the supporting assembly to drive the supporting part in the supporting assembly to support the belt, thereby facilitating the replacement of the supporting roller under the belt.

[0007] Further, the supporting assembly further comprises a supporting rod, and the supporting part is spaced apart from each other along the extension direction of the supporting rod, and rotating the supporting rod drives the supporting part to uniformly support the belt.

[0008] Further, the supporting part comprises a first supporting frame and a second supporting frame fixedly connected with the supporting rod, and the first supporting frame and the second supporting frame are arranged at an acute angle.

[0009] Further, the first supporting frame and the second supporting frame are respectively arranged perpendicular to the supporting rod, and the first supporting frame is in contact with the belt when the supporting rod is rotated, and the end of the first supporting frame is provided with a transmission wheel.

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Terms such as "upper," "lower," "left," "right," and "top" indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are used only for the convenience of describing the present invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0027] like Figures 1 to 7 As shown, an idler replacement auxiliary device includes a support assembly and a support assembly for supporting the support assembly. The support assembly and the support assembly are detachably connected, and the support assembly can rotate relative to the support assembly to drive the support part in the support assembly to support the belt, thereby facilitating the replacement of the idler under the belt.

[0028] By setting up a support component to support the support component, the support component is given a certain height. The support component is driven to rotate on the support component, which in turn drives the support part to rotate so that it contacts and supports the lower surface of the belt. Increasing the height of the belt increases the distance between it and the idler roller, thereby forming a stable operating space. This facilitates the disassembly or replacement of the idler roller, enabling time-saving, labor-saving, and safe replacement of the idler roller, and greatly reducing the labor intensity on site.

[0029] In the idler replacement auxiliary device of this embodiment, the support assembly further includes a support rod 1. The support parts are arranged in several groups at intervals along the extension direction of the support rod 1. Rotating the support rod 1 drives the several groups of support parts to evenly support the belt.

[0030] The support rod 1 is set to fix the support part. By rotating the support rod 1, the support part is driven to rotate, so that the support part is close to the belt and gradually lifts the belt to increase the height of the belt, so that there is enough space between the belt and the idler for replacement operation. Multiple sets of support parts are set to support the belt evenly along the width of the belt, so that the idler at each position has enough space to be replaced, while avoiding concentrated stress on the belt and causing damage.

[0031] Preferably, in this embodiment, the support portion is provided with two sets to support the belt from both sides, matching the three idler rollers.

[0032] In the roller replacement auxiliary device of this embodiment, the supporting part includes a first supporting frame 2 and a second supporting frame 3 fixedly connected to the supporting rod 1, and the first supporting frame 2 and the second supporting frame 3 are arranged at an acute angle.

[0033] Specifically, after rotating the support rod 1 to a suitable angle, the tops of the first support frame 2 and the second support frame 3 respectively contact the belt and provide support. The two sets of support parts have four positions for support, which increases the contact area between the support parts and the belt. The first support frame 2 and the second support frame 3 are set at an acute angle to avoid the distance between the two support frames and the belt contact points being too large, resulting in insufficient support height for the belt and difficulty in meeting the needs of idler roller replacement.

[0034] In the roller replacement auxiliary device of this embodiment, the first support frame 2 and the second support frame 3 are respectively arranged perpendicular to the support rod 1. When the support rod 1 is rotated, the first support frame 2 first contacts the belt and the end of the first support frame 2 is provided with a transmission wheel 4.

[0035] Specifically, when the support rod 1 is rotated, the first support frame 2 located at the front of the rotation direction first contacts the belt. In order to prevent the end of the first support frame 2 from damaging the belt during the process of supporting and lifting the belt, a transmission wheel 4 is provided at the end of the first support frame 2. The side of the transmission wheel 4 is arc-shaped to avoid damaging the belt when it contacts the belt.

[0036] Preferably, a drive wheel 4 can also be provided at the end of the second support frame 3, so as to facilitate the rotation of the support rod 1 from two directions and allow either support frame to support the belt through the drive wheel 4, thereby improving practicality.

[0037] In the roller replacement auxiliary device of this embodiment, the support assembly includes a first support frame 5 and a second support frame 6 located on both sides of the support rod 1. The first support frame 5 and the second support frame 6 are respectively installed on the conveyor frame to achieve positioning.

[0038] The first support frame 5 and the second support frame 6 are set up to support the support rod 1 from both sides, so that the support rod 1 can rotate stably. In use, first fix the two support frames on the frame on both sides of the conveyor, then install the support rod 1 at a suitable height on the support frame, and then rotate the support rod 1 to drive the support part to rotate and support and lift the belt.

[0039] Preferably, the first support frame 5 and the second support frame 6 can be positioned and fixed according to different belt widths, thereby cooperating with different positions of the support rod 1 to provide support for the support rod 1, expanding the adaptability of the replacement auxiliary device and improving its practicality. The advantage of this device is that it does not limit the width of the belt conveyor; belts of 600mm to 1600mm can be used in coal preparation plant systems.

[0040] In the roller replacement auxiliary device of this embodiment, one end of the support rod 1 is provided with a handle 7 so that the support rod 1 and the support part can be rotated by rotating the handle 7, thereby supporting the belt and increasing the distance between the belt and the roller.

[0041] Specifically, the handle 7 is formed by bending the support rod 1. In addition, a sleeve is detachably fitted on the outside of the handle 7 to increase the length of the handle 7. The lever principle is used to reduce the difficulty of turning the handle 7 and the support rod 1, and further reduce the amount of labor.

[0042] In the roller replacement auxiliary device of this embodiment, the first support frame 5 is located at the end of the support rod 1 away from the handle 7, and the first support frame 5 is provided with a plurality of limiting holes 8 to limit the end of the support rod 1 from different heights.

[0043] Specifically, after fixing the first support frame 5, the end of the support rod 1 is inserted into the limiting hole 8, and then the handle 7 is assembled with the second support frame 6 to fix the support rod 1. Multiple limiting holes 8 are set along the height direction of the first support frame 5 to facilitate the adjustment of the height of the support rod 1 to adapt to belts of different heights and improve practicality.

[0044] In the roller replacement auxiliary device of this embodiment, the second support frame 6 is located at the end of the support rod 1 near the handle 7. Multiple limiting grooves 9 are respectively opened on both sides of the second support frame 6. The support rod 1 cooperates with the limiting grooves 9 to achieve height positioning.

[0045] The limiting groove 9 is located on the side of the second support frame 6, so that the end of the support rod 1 can be inserted into the limiting hole 8 and then cooperate with the second support frame 6 from one side to achieve the height positioning of the support rod 1; the setting of multiple limiting grooves 9 and matching of limiting holes 8 makes the support rod 1 as horizontal as possible.

[0046] In the roller replacement auxiliary device of this embodiment, the ends of the first support frame 5 and the second support frame 6 are respectively provided with connecting parts. The connecting parts have an L-shaped bending structure, and a positioning bolt 10 is provided between the connecting parts and the first support frame 5 or the second support frame 6.

[0047] Specifically, the connecting part facilitates the fixed connection between the support frame and the machine frame to provide stable support for the support rod 1. In addition, the L-shaped connecting part and the support frame form a U-shaped groove, which can realize the upside-down installation of the support frame, thereby reducing the requirements of the support rod 1 on the installation environment and expanding the range of applications.

[0048] Preferably, the support frame and the connecting part are respectively provided with multiple corresponding bolt mounting holes, so that after the connecting part is snapped into the frame or other positions, the support frame can be fixed by the positioning bolts 10 cooperating with the bolt mounting holes at appropriate positions.
