DETAILED DESCRIPTION OF THE EMBODIMENTS
[0031] The following Figures 1-6 further describes the present application in detail with reference to the attached drawings.
[0032] The present application discloses a idler handling device.
[0033] Embodiment 1 Refer to Figure 1, the idler conveying device includes a frame 1, and wheels 11 are installed at the bottom of the frame 1. Above the frame 1, a bracket 12 is installed. The bracket 12 is an arc-shaped plate 22 with an upward opening, and the inner arc surface of the arc-shaped plate 22 is above the outer arc surface of the arc-shaped plate 22. Baffles 13 are respectively arranged on both sides of the bracket 12, and a relief groove 131 for placing the idler rotating shaft is opened on the top surface of the baffle 13. A limiting member 2 for limiting the idler is arranged on the bracket 12. The limiting member 2 includes a steel wire rope 21. The steel wire rope 21 can be wound around the outer periphery of the bracket 12 to limit the idler inside the bracket 12 and protect the idler from slipping off the bracket 12 easily.
[0034] The implementation principle of Embodiment 1 of this application is as follows: When the idler needs to be replaced, the damaged idler or the new idler is placed on the bracket 12, and the rotation of the damaged idler or the new idler is placed in the relief groove 131. Then, the limiting member 2 is used to limit the damaged idler or the new idler, and the staff can transfer the damaged idler or the new idler, effectively solving the problem of replacing the idler when large equipment cannot reach the site. And because the frame 1 is small, it has good mobility and can easily shuttle between narrow spaces and complex terrains, and can also move flexibly on muddy roads. The stable load-bearing performance of the bracket 12 can ensure that the idler will not slip during transportation, not only reducing the dependence on large mechanical equipment, reducing the production stagnation time caused by poor road conditions, but also saving manpower and material resources, and improving the safety and efficiency of the replacement work.
[0035] Embodiment 2 Refer to Figure 2 and Figure 3 , the difference between this embodiment and Embodiment 1 is that a first buffer pad 3 is arranged on the inner arc surface of the bracket 12, and second buffer pads 31 are arranged on the relative inner sides of the two baffles 13. A buffer groove 32 is opened on the inner arc surface of the bracket 12, and a buffer block 33 is installed on the bracket 12 to slide vertically along the buffer groove 32. A buffer spring 34 is fixed to the bottom surface of the buffer block 33, and the bottom end of the buffer spring 34 is fixedly connected to the inner bottom surface of the buffer groove 32.
[0036] The implementation principle of Embodiment 2 of this application is as follows: When the idler is placed in the bracket 12, the idler first contacts the buffer block 33. The buffer block 33 first buffers the idler under the action of the buffer spring 34. The first buffer pad 3 can contact the outer periphery of the idler, and the second buffer pads 31 can contact the end surface of the idler, reducing the vibration of the idler due to poor terrain during transportation and protecting the idler.
[0037] Embodiment 3 Refer to Figure 4 and Figure 5, The difference between this embodiment and Embodiment 1 is that the limiting member 2 includes two arc-shaped plates 22. One end of the arc-shaped plate 22 is hinged to the top of the bracket 12, and a plug block 23 is fixed to the other end of the arc-shaped plate 22. A slot 121 for inserting the plug block 23 is formed in the top surface of the bracket 12.
[0038] Referring to Figure 6 , a positioning groove 41 is formed in the inner wall of the slot 121. The bracket 12 is slidably installed with a positioning block 4 along its own length direction through the positioning groove 41. A plugging groove 231 for inserting the positioning block 4 is formed in the side surface of the plug block 23. A first inclined surface 42 is arranged on the top surface of the positioning block 4, and the first inclined surface 42 is located on the side of the positioning block 4 close to the slot 121. A positioning spring 43 is fixed to the side surface of the positioning block 4 away from the slot 121, and one end of the positioning spring 43 away from the positioning block 4 is fixedly connected to the inner wall of the positioning groove 41.
[0039] When the plug block 23 is inserted into the slot 121, the plug block 23 abuts against the first inclined surface 42 and pushes the positioning block 4 into the positioning groove 41. When the plug block 23 completely enters the slot 121, the positioning block 4 moves towards the direction close to the plug block 23 under the elastic force of the positioning spring 43 and is inserted into the plugging groove 231. The positioning block 4 limits the plug block 23, thereby limiting the arc-shaped plate 22.
[0040] Referring to Figure 6 , a pressing groove 51 communicating with the positioning groove 41 is formed in the top surface of the bracket 12. The bracket 12 is slidably installed with a pressing block 5 along the vertical direction through the pressing groove 51. A positioning through groove 44 for inserting the pressing block 5 is formed in the top surface of the positioning block 4. A second inclined surface 441 is arranged on the inner wall of the positioning through groove 44 away from the slot 121. A third inclined surface 52 for abutting against the second inclined surface 441 is arranged on the bottom surface of the pressing block 5. A reset block 53 is fixed to the side surface of the pressing block 5. A reset groove 54 is formed in the inner wall of the pressing groove 51. The reset block 53 is slidably matched with the bracket 12 along the vertical direction through the reset groove 54. A reset spring 55 is fixed to the top surface of the reset block 53, and the top end of the reset spring 55 is fixedly connected to the inner top surface of the reset groove 54.
[0041] When the pressing block 5 is pushed downward, the second inclined surface 441 abuts against the third inclined surface 52, and the pressing block 5 pushes the positioning block 4 towards the direction away from the plug block 23, so that the positioning block 4 disengages from the plugging groove 231, and the limit of the positioning block 4 on the plug block 23 is released, facilitating the staff to load and unload the idler after opening the arc-shaped plate 22.
[0042] Referring to Figure 5 , a sliding groove 61 is formed in the inner arc surface of the bracket 12. A bidirectional lead screw 6 is rotatably installed in the sliding groove 61. One end of the bidirectional lead screw 6 extends out of the bracket 12 and is fixed with a handle 62. A slider 132 is fixed to the bottom surface of the baffle 13. The slider 132 is sleeved on the outer periphery of the bidirectional lead screw 6, and the slider 132 is in threaded sliding fit with the bidirectional lead screw 6.
[0043] After placing the roller in the bracket 12, turn the handle 62 to rotate the bidirectional screw 6, which drives the baffle 13 to move toward the direction close to the roller, so that the rotating shaft of the roller can be inserted into the clearance groove 131, and rollers of different lengths can be limited. The implementation principle of Example 3 of the present application is as follows: after placing the roller on the bracket 12, rotate the arc plate 22 so that the plug block 23 is inserted into the slot 121, and the positioning block 4 is inserted into the plug-in slot 231 under the elastic force of the positioning spring 43. The positioning block 4 limits the plug block 23, thereby realizing the clamping fixation of the arc plate 22 and the bracket 12, so that the arc plate 22 can protect the roller conveniently and quickly.
[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
