DETAILED DESCRIPTION

[0019] In order to make the technical personnel of the present application have a better understanding of the technical scheme in the present application, the following will be a clear and complete description of the technical scheme in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present patent, other embodiments obtained by the ordinary skilled in the art without creative labor are within the scope of protection of the present patent.

[0020] As shown in the drawings, Figs. 1 to 3 The present embodiment discloses a belt conveyor carrier roller replacement device, which comprises a lower support frame 2, an upper support frame 4, a jack 3 and a guide column 5. Among them, the lower support frame 2 and the upper support frame 4 are horizontally arranged, the guide column 5 vertically penetrates the end of the lower support frame 2 and the upper support frame 4, and the jack 3 is supported between the lower support frame 2 and the upper support frame 4. When the jack 3 is raised, the upper support frame 4 can be raised, which will further drive the belt to be lifted, so as to complete the replacement of the carrier roller.

[0021] In the present embodiment, asFig. 1 As shown, the lower support frame 2 is elongated and installed above the conveyor frame 1, with its extension direction perpendicular to the belt direction. The upper support frame 4 is also elongated and located directly above the lower support frame 2. The ends of the lower support frame 2 and the upper support frame 4 are located on opposite sides of the conveyor and are each penetrated by two guide posts 55. The guide posts 5 are vertically positioned, with their lower ends fixed to the ground to ensure the stability of the entire device during lifting and lowering, while also ensuring the vertical movement of the upper support frame 4, thereby effectively supporting the belt.

[0022] To further improve the stability of the device, mounting grooves 6 are welded and fixed to the bottom of the lower support frame 2 near both ends. The mounting grooves 6 have downward-facing openings that can engage with the top of the conveyor belt frame 1. During the use of this device, as the upper support frame 4 rises, the entire device may sway along the belt direction. Therefore, by engaging the mounting grooves 6 at the bottom of the lower support frame 2 with the conveyor belt frame 1, the swaying of the device during use can be effectively prevented, thus improving stability.

[0023] In this embodiment, the jack 3 is preferably a scissor jack. The bottom and top of the jack 3 are respectively fixed with a lower locking groove 7 and an upper locking groove 8. The lower locking groove 7 engages above the middle of the lower support frame 2, and the upper locking groove 8 engages below the middle of the upper support frame 4. Scissor jacks are characterized by their compact structure; therefore, using a scissor jack ensures that the device can be placed within the space at the bottom of the belt during use, which is beneficial for the installation and disassembly of the jack 3.

[0024] For ease of operation, the scissor jack also includes a hand crank 9. One end of the hand crank 9 can be connected to one end of the screw in the scissor jack, and the other end is equipped with a handle. Specifically, as shown... Fig. 3 As shown, one end of the screw has a round hole, and one end of the hand crank 9 has a hook. When using the hand crank 9, the hook is inserted into the round hole at the end of the screw, and then the handle is turned. Thus, the screw in the scissor jack is rotated by the hand crank 9 to achieve the lifting function, which is convenient to operate. At the same time, the handle also saves effort.

[0025] Furthermore, the conveyor belt idler replacement device of this embodiment also includes two bases 10. Each base 10 has mounting holes, and the bottom end of the guide post 5 is threaded or inserted into the mounting holes of the base 10. The bases 10 further improve the stability of the guide post 5, ensuring that the guide post 5 remains vertical.

[0026] The operation process of this utility model is as follows:

[0027] First install the lower support frame 2, wherein the mounting groove 6 is engaged on the belt conveyor frame 1, then place the jack 3 in the middle of the lower support frame 2, so that the lower clamping groove 7 of the jack 3 is engaged above the lower support frame 2, then place the upper support frame 4, so that the middle part of the upper support frame 4 is engaged with the upper clamping groove 8 of the jack 3; Then install the guide column 5, vertically downwardly pass the end of the upper support frame 4 and the end of the lower support frame 2 in sequence, and then insert or threadedly install in the base 10. When the jack 3 is raised, the upper support frame 4 can be raised, and the belt is lifted, and the replacement of the carrier roller can be carried out when the belt is lifted to a certain height.
