[0025] The lifting and adjusting device includes a support rod 3 connected to a connecting rod 101 on one side and a lifting assembly connected to a placement rack 10 arranged on the other side of the support rod 3, the lifting assembly includes a first support rod 31 and a second support rod 32 hingedly connected in the middle, one end of the first support rod 31 is hingedly connected to the support rod 3, a connecting plate 14 is provided at the lower end of the placement rack 10, a sliding groove 141 is provided on the connecting plate 14, a pin 311 is provided at a position on the first support rod 31 corresponding to the sliding groove 141, and the pin 311 extends into the sliding groove 141.

[0026] One end of the second support rod 32 is hingedly connected to the connecting plate 14, and the other end is hingedly provided with a slider 33. The slider 33 is fittedly arranged on the support rod 3. A support plate 34 is provided on one side of the support rod 3. A rotating shaft 35 with a handle rod is passed through the support plate 34, and the protruding end of the rotating shaft 35 is screwed and connected to the slider 33. A guide groove 30 is provided on the support rod 3, and a directional rod 331 extending into the guide groove 30 is provided on the slider 33.

[0027] A slope 15 is provided on one side of the bottom plate 1 , and a placement groove is provided on the placement rack 10 . The plane where the notch of the placement groove is located is flush with the plane where the upper end surface of the bottom plate 1 is located. A hemispherical boss 17 is provided on both the bottom plate 1 and the slope 15 .

[0028] The operating principle of the utility model is as follows:

[0029] like Figures 1 to 3 As shown, in order to improve the efficiency of transporting the rubber roller, a power motor 13 for rotating the support plate 12 and a drive motor 2 for lifting the connecting block 20 are provided. It should be noted that in order to facilitate the power supply to the two motors, a power supply should be provided at the edge of the bottom plate 1 without affecting the transport of the rubber roller. The power supply should preferably be a battery (not shown) with considerable power. At the same time, in order to facilitate operation, an operating table (not shown) for controlling the switches of the two motors should also be provided, and the operating table is also electrically connected to the battery. These are all existing well-known technologies, and the relevant connection setting status will not be repeated here.

[0030] When in use, first push the bottom plate 1 to be driven by the roller 16 to move to the vicinity of the installation position of the rubber roller, and ensure that the placement rack 10 directly above does not interfere with the movement of the equipment. Then, move the rubber roller to the position of the inclined surface 15, and push the rubber roller onto the bottom plate 1 along the inclined surface 15. Among them, both the bottom plate 1 and the inclined surface 15 are provided with hemispherical bosses 17, which reduces the contact area and reduces the resistance to the movement of the rubber roller. At the same time, the plane where the notch of the placement groove is located is flush with the plane where the upper end surface of the bottom plate 1 is located, so that the rubber roller can be pushed from the bottom plate 1 into the placement groove. At this time, the connecting shafts at both ends of the rubber roller are protruding from the placement rack 10.

[0031] Then, start the driving motor 2 from the operating table, and the rotation of the threaded rod 21 drives the connecting block 20 to move upward along the axial direction of the guide rod 11, that is, it drives the support rod 3 connected to the connecting block 20 to move upward synchronously, and the placement frame 10 connected to the support rod 3 and the rubber roller in the placement groove also move upward synchronously. After moving up to a certain height, turn off the driving motor 2, and then start the power motor 13 from the operating table to drive the support plate 12 to rotate in the horizontal direction, and synchronously drive the guide rod 11 and the connecting block 20 to rotate in the horizontal direction, that is, the rubber roller in the placement groove also rotates in the horizontal direction synchronously and moves to the vicinity of the installation position. At this time, the connecting shafts at both ends of the rubber roller are located below the installation position. At this time, the height of the rubber roller needs to be raised again.

[0032] The cam 331 is then rotated in the direction of the left and right sides of the first support rod 31 so that the cam 331 can be rotated in the direction of the right and left sides of the first support rod 31.

[0033] Similarly, when the rubber roller needs to be replaced, the old rubber roller needs to be removed first. At this time, the placement rack 10 is moved to the bottom of the old rubber roller according to the aforementioned related operations, and the placement rack 10 is fine-tuned to move up, and the placement groove supports the old rubber roller. Then, the connection with the connecting shaft of the rubber roller is loosened from the equipment. Then, the handle rod on the rotating shaft 35 is rotated in the opposite direction, and the placement rack 10 is moved down and away from the installation position. Subsequently, the power motor 13 is started on the operating table to drive the support frame 10 to rotate horizontally to leave the equipment area, and the drive motor 2 is started again to lower the placement rack 10, and the old rubber roller is taken out and placed on the bottom plate 1, and finally moved to the carrier via the inclined surface 15 for centralized storage; the next step is to replace the new rubber roller, which can be implemented according to the aforementioned related operations, which will not be repeated here.

[0034] In addition, setting scale lines (not marked) on the guide rod 11 helps the operator remember the lifting height values ​​required for disassembling and assembling the rubber rollers of equipment of different specifications, and also helps to improve the efficiency of disassembly and assembly; the connection position between the connecting rod 101 and the placement rack 10 should avoid the axial center line of the placement rack 10 to avoid movement interference with the central axis of the rubber roller, so that the rubber roller cannot fall into the placement groove and is easy to fall out.

[0035] In addition, in order to improve the force strength, it is appropriate to symmetrically set two first support rods 31 and two second support rods 32. Therefore, at this time, the slider 33 hinged to the second support rod 32 is also correspondingly set to two, and a connecting piece (not marked) that is in contact with the upper end surface of the support rod 3 is set between the two sliders 33. The connecting piece is screwed to the rotating shaft 35, which can also achieve the use effect of this embodiment and will not be repeated here.
