[0021] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figures 1-4An embodiment of the utility model provides a new roller installation device, including a roller changing vehicle body 1, on which is provided a new roller box 3, a roller placing platform 4, a lifting drive mechanism 41 for driving the roller placing platform 4 to rise and fall between a roller changing station and a roller handover station, and a new roller transfer mechanism for transferring the rollers in the new roller box 3 to the roller placing platform 4.

[0023] The new roller transfer mechanism is arranged between the new roller box 3 and the roller handover station, and includes a roller handover arm 5 and a first rotation drive unit 51. The roller handover arm 5 is connected to the first rotation drive unit 51 and has a roller receiving position docking with the new roller box 3 and an upper roller position docking with the roller placing platform 4 at the roller handover station.

[0024] The roll-changing vehicle body 1 is preferably provided with traveling wheels 11 , and more preferably provided with a traveling drive mechanism 12 , so that the roll-changing vehicle body 1 can travel on its own.

[0025] Under the action of the lifting drive mechanism 41, the roller support platform 4 has a roller changing station and a roller handover station. The roller changing operation and the roller handover operation are performed at different heights, and the two operations do not interfere with each other, which can ensure operating space and ensure operational safety. Among them, preferably, the roller changing station is located above the roller handover station.

[0026] There can be multiple roller interfacing arms 5, each of which is spaced apart along the roller axis. Alternatively, the roller interfacing arm 5 includes multiple arm segments, each of which is spaced apart along the roller axis. This can stably support the interfacing rollers while avoiding the excessive weight of the roller interfacing arm 5 when it adopts a continuous long rod structure. Each roller interfacing arm 5 / arm segment is preferably driven by the same rotary drive device. For example, each roller interfacing arm 5 / arm segment is serially connected to a synchronous connecting rod, which is connected to the first rotary drive unit 51.

[0027] The first rotation drive unit 51 may include an automatic drive device such as a motor, or may be driven by a handwheel.

[0028] Preferably, in order to facilitate smooth handover of the rollers, when the roller handover arm 5 is in the roller receiving position, its roller receiving end is lower than the roller outlet of the new roller box 3; when the roller handover arm 5 is in the upper roller position, its upper roller end is higher than the table surface of the roller supporting platform 4.

[0029] Preferably, the roller handover arm 5 has a roller receiving groove suitable for receiving the roller, which can reliably and smoothly hand over the roller; further, Figure 1 and Figure 3The roller joining groove is a V-shaped groove, which provides greater stability for the rollers and allows for smoother movement of the rollers in and out of the joining arms. Obviously, an arc-shaped groove is also feasible. At the roller joining position, the first groove wall 501 of the V-shaped groove engages with the roller outlet of the new roller box 3. As mentioned above, the notch end of the first groove wall 501 is preferably lower than the roller outlet of the new roller box 3. At the upper roller position, the second groove wall 502 of the V-shaped groove engages with the roller support platform 4. As mentioned above, the notch end of the second groove wall 502 is preferably higher than the surface of the roller support platform 4.

[0030] Preferably, the depth of the roller connecting groove allows it to accommodate only one roller, which is convenient for on-site operation.

[0031] Furthermore, if Figure 1 and Figure 3 The roller-joining arm 5 has an arcuate stop surface 503 connected to the notch end of the first groove wall 501. As the roller-joining arm 5 rotates, the arcuate stop surface 503 can rise to block the roller outlet of the new roller cassette 3, and then descend to below the notch end of the first groove wall 501, thereby connecting the roller-joining groove with the new roller cassette 3. Therefore, the provision of the arcuate stop surface 503 ensures the safety and reliability of roller joining.

[0032] In one embodiment, a lifting frame 42 is provided on the roller changing vehicle body 1, and the roller supporting platform 4 is slidably arranged on the lifting frame 42. The lifting drive mechanism 41 can be arranged on the roller changing vehicle body 1 or installed on the lifting frame 42. Preferably, as Figure 1-Figure 3 Two door-shaped frames are set on the roller changing vehicle body 1 to constitute the above-mentioned lifting frame 42; lifting guide rails are set on the door-shaped frames, and the roller placing platform 4 slides along the lifting guide rails to ensure the stability of the lifting movement.

[0033] The lifting drive mechanism 41 includes but is not limited to linear drive devices such as air cylinders and hydraulic cylinders.

[0034] The new roller box 3 is preferably open at the top to facilitate the placement and removal of the rollers. Preferably, a detachable baffle 8 is provided on the side of the new roller box 3 facing the roller holding platform 4, and when the baffle 8 is removed, the rollers can be allowed to be placed in and out of the side.

[0035] The bottom of the new roller box 3 preferably adopts a frame structure, for example, including a plurality of new roller supporting rods 31 arranged in sequence and spaced apart along the longitudinal direction. This structure can reduce the weight of the new roller box 3.

[0036] Therefore, when the new roller box 3 is detachably arranged on the roller changing car body 1, the production convenience can be improved. For example, several new rollers can be placed in the new roller box 3 and then lifted together onto the roller changing car body 1. This can prevent the rollers from being lifted on the roller changing car body 1, which is safer and more convenient.

[0037] In one embodiment, Figures 1-4 The surface of the roller supporting platform 4 is provided with at least one roller supporting groove 43 suitable for supporting the roller.

[0038] In this embodiment, a plurality of roller grooves 43 are provided on the roller supporting platform 4, and the plurality of roller grooves 43 are arranged in a connected manner in a transverse direction. Based on this solution, the roller supporting platform 4 can buffer multiple rollers, which can improve the efficiency and flexibility of the roller changing operation, including but not limited to:

[0039] Multiple new rollers can be placed on the roller support platform 4, and then the roller support platform 4 is lifted to the roller changing station, so that multiple new rollers can be installed at one time;

[0040] Multiple old rollers can be removed at one time and placed on the roller placing platform 4, and then the roller placing platform 4 is lowered to the roller handover station to send away the old rollers;

[0041] At the roll changing station, the old roll can be removed to the roll supporting platform 4, and then the new roll on the roll supporting platform 4 can be installed on the corresponding equipment (such as a rolling mill), so the old roll removal and new roll installation operations can be completed at the same time.

[0042] The above-mentioned roller grooves 43 are preferably V-shaped grooves or arc-shaped grooves; the roller grooves 43 are preferably shallow grooves to facilitate the rollers to flow between the roller grooves 43.

[0043] In one embodiment, the roller supporting platform 4 includes a platform body and a plurality of supporting seats, each supporting seat is arranged at intervals in the longitudinal direction on the top of the platform body, and each supporting seat is provided with the above-mentioned roller groove 43; this structure can reduce the weight of the roller supporting platform 4.

[0044] Preferably, the bottom of the new roller box 3 has a slope toward the roller holding platform 4, and the rollers can be automatically discharged from the roller outlet of the new roller box 3 by relying on their own weight and the squeezing effect of the rear rollers.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
