[0022] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0023] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0024] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0025] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0026] like Figures 1 to 3 As shown in the figure, this utility model embodiment provides an auxiliary tooling for disassembling and assembling conveyor idlers, which includes a support frame 31, a support plate 11, a handcart 21, and a lifting mechanism. The support frame 31 is a rectangular frame, and the extension direction of the support frame is perpendicular to the extension direction of the support plate. The middle position of the support frame is located on the top surface of the support plate 11. Support rollers 32 are rotatably arranged on the left and right sides of the support frame, and the extension direction of the support rollers 32 is the same as the extension direction of the support plate. The support frame has an arc-shaped structure that is high at both ends and low in the middle. The lifting mechanism is located between the bottom surface of the support plate 11 and the handcart.

[0027] The conveyor idler roller assembly / disassembly auxiliary tool provided in this embodiment of the utility model utilizes the middle position of the support frame 31 to support the idler roller. Since the support frame has an arc-shaped structure with higher ends and a lower middle, and support rollers are installed on both sides, this design effectively limits the idler roller's position, preventing it from swaying and falling. Then, the lifting mechanism can raise and lower the support plate 11, thereby moving the support frame 31 and the idler roller to the required height. Furthermore, a handcart allows for convenient and labor-saving movement of the support frame and idler roller to the desired position. Therefore, this utility model effectively supports, moves, and adjusts the height of the idler roller without requiring multiple people to lift it, thus avoiding uneven force on the idler roller. This makes the installation and disassembly of the idler roller more convenient, saving manpower and reducing the labor intensity of maintenance personnel.

[0028] Furthermore, at least two support rollers are rotatably arranged on both the left and right sides of the support frame 31, thereby providing better support and limiting of the idler rollers. The left end 33 and the right end 34 of the support frame can be at the same height.

[0029] Specifically, the support frame 31 includes a left frame and a right frame. The right end of the left frame is detachably connected to the left end of the right frame, so that the left frame and the right frame can be easily replaced or repaired, saving maintenance costs.

[0030] Preferably, connecting pieces 35 are provided on both the front and rear side plates of the right end of the left frame, and notches 37 for accommodating the connecting pieces are provided on both the front and rear side plates of the left end of the right frame. The two notches correspond one-to-one with the two connecting pieces; the connecting pieces are detachably connected to the notches. This design allows for a detachable connection between the connecting pieces and the notches, thus achieving a detachable connection between the left and right frames.

[0031] Furthermore, the connecting piece 35 has multiple mounting holes 36 extending in its extension direction for the threaded sections of the fastening bolts to pass through, and the bottom surface of the notch 37 has screw holes 38 for engaging with the threaded sections of the fastening bolts. With this design, during use, different mounting holes are aligned with the screw holes, and then fastening is performed using the fastening bolts. This allows for easy adjustment of the mating length between the connecting piece and the notch, thereby facilitating the adjustment of the length of the middle section of the support frame and the overall length of the support frame. This allows for adjustment of the support frame length according to the needs of the disassembly and assembly environment, better meeting the usage requirements of different disassembly and assembly environments. Preferably, the support frame is evenly divided into a left frame and a right frame, both of which are the same size; the number of screw holes on the bottom surface of the notch can be two, ensuring a more secure and reliable connection between the left and right frames.

[0032] Understandably, the handcart can be a commonly used handcart with wheels at the bottom, allowing it to move on the ground; the lifting mechanism can be a commonly used hydraulic lifting mechanism, and the handcart can be equipped with control buttons to easily control the raising, lowering, starting, and stopping of the lifting mechanism. The support plate can be a rectangular plate.

[0033] Because the idler rollers in the conveyor are positioned at different heights, it is both difficult and dangerous to replace an idler roller that is located at a higher position when it is damaged. This utility model designs the support frame with a structure that is high at both ends and low in the middle, and the support rollers are rotatably installed on both sides of the support frame. This can effectively prevent the idler roller from falling off due to left and right swaying after it is placed in the middle position of the support frame. In other words, this structure design with high ends and low middle can lock the idler roller between the two support rollers to prevent it from falling off.

[0034] During disassembly, the support frame is raised using a lifting mechanism, and the middle position of the support frame is used to support the idler rollers removed from the conveyor. Then, the lifting mechanism is used to lower the support frame, and a handcart is pushed to transport the disassembled idler rollers to the designated position. During installation, the idler rollers are placed in the middle position of the support frame, and then the handcart is pushed to transport them under the conveyor. The lifting mechanism is then used to raise the support frame and idler rollers to the required height for installation. After the idler rollers are installed, the lifting mechanism lowers the support frame to the initial position.

[0035] In one specific embodiment, one end of the trolley 21 has two opposing elongated support seats 22, the extension direction of the support seats 22 is the same as the extension direction of the support plate 11, the lifting mechanism is arranged between the two support seats and the bottom surface of the support plate, and the bottom of the support seats and the bottom of the trolley are provided with rollers, so that the support frame can be easily moved to the required position.

[0036] Specifically, each of the mounting holes is evenly distributed along the extension direction of the connecting piece.

[0037] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
