Description

Technical Field

[0001] The utility model relates to the technical field of roller changing equipment, in particular to a transverse track mechanism and a transverse roller changing device. Background Art

[0002] During the rolling process, the work and backup rolls of a rolling mill are subject to significant alternating loads and pressures. These alternating loads and pressures can easily cause cracks to form on the roll surfaces. Furthermore, during hot rolling, thermal stresses can further increase the risk of cracks. Failure to promptly replace these cracks can lead to further expansion of the cracks, compromising product quality and potentially causing roll surface detachment and breakage. Therefore, timely replacement of damaged rolls is essential.

[0003] In order to speed up the roller changing speed in the prior art, a roller feed track and a transverse track are usually arranged to intersect each other. A roller feed device is provided on the roller feed track, and a transverse device is provided on the transverse track. In order to avoid interference between the roller feed track and the transverse track, a section of rotating track is usually provided on the transverse track for the roller feed track to pass through. By controlling the rotating track, space can be made for the roller feed device to pass through, thereby avoiding affecting the normal operation of the roller feed device. However, in the rotating track of the prior art, the rotating guide rail is hingedly arranged on the transverse track. Due to the lack of support below the rotating guide rail, the rotating guide rail has a larger track beam bearing span, which makes the rotating guide rail prone to deflection and deformation during use, thereby causing a height difference between the rotating track and the working roll track of the rolling mill, seriously affecting the operating stability of the transverse device. Utility Model Content

When the rotating transverse track is in a state of connecting the first transverse track and the second transverse track, the two ends of the rotating transverse track are respectively overlapped on the first support portion and the second support portion.

[0010] In a preferred embodiment of the present invention, the track support structure also includes at least one third support portion arranged between the first support portion and the second support portion, and when the rotating and transverse track is in a state of connecting the first and second transverse tracks, the rotating and transverse track is overlapped on the third support portion.

[0011] In a preferred embodiment of the present invention, a roller-changing rail mechanism is provided below the rotating and transverse moving rail, and the roller-changing rail mechanism includes two roller-changing guide rails arranged in parallel. The third support portion is composed of the roller-changing guide rails. When the rotating and transverse moving rails are in a state of connecting the first and second transverse moving rails, the rotating and transverse moving rails are overlapped on the two roller-changing guide rails.

[0012] In a preferred embodiment of the present invention, the rotating and transverse track includes two rotating and transverse guide rails arranged side by side, wherein one of the rotating and transverse guide rails is hinged to the first transverse track, and the other rotating and transverse guide rail is hinged to the second transverse track.

[0013] In a preferred embodiment of the present invention, the transverse track mechanism also includes a rotation drive device, which is connected to the rotating transverse track, and the rotation drive device is used to push the rotating transverse track to controllably connect the first transverse track and the second transverse track.

[0014] The embodiment of the present invention further provides a transverse roller changing device, comprising:

[0015] The aforementioned transverse track mechanism;

[0016] A transverse roller device is movably arranged on the transverse track mechanism.

[0017] In a preferred embodiment of the present invention, the transverse roller device includes a first transverse roller vehicle and a second transverse roller vehicle, and the first transverse roller vehicle and the second transverse roller vehicle can be movably arranged on the transverse track mechanism.

[0018] In a preferred embodiment of the present invention, the transverse roller changing device also includes a guide structure, and the guide structure includes a first guide slide arranged on the first transverse roller trolley, a second guide slide arranged on the second transverse roller trolley, and a transverse guide slide arranged on the transverse rail mechanism, the first transverse roller trolley and the transverse rail mechanism are slidably matched with each other through the first guide slide and the transverse guide slide, and the second transverse roller trolley and the transverse rail mechanism are slidably matched with each other through the second guide slide and the transverse guide slide.

[0019] In a preferred embodiment of the present invention, the transverse roller changing device also includes a first transverse driving device and a second transverse driving device, the first transverse driving device is connected to the first transverse roller vehicle, and the second transverse driving device is connected to the second transverse roller vehicle.

[0020] In a preferred embodiment of the present invention, the first transverse roller vehicle is provided with a first connecting portion, the second transverse roller vehicle is provided with a second connecting portion, and the first connecting portion and the second connecting portion are detachably connected.

Driven by the second transverse roller vehicle, the second telescopic cover plate can telescopically cover the second transverse track.

[0024] The technical solution of the utility model has the following significant beneficial effects:

[0025] When the transverse track mechanism described in the embodiment of the present invention is in use, the first and second transverse tracks are spaced apart in the same direction, and the rotating transverse track controllably connects the first and second transverse tracks. When the rotating transverse track connects the first and second transverse tracks, the transverse roller assembly can be moved along the transverse track mechanism to facilitate roller replacement. When the rotating transverse track disconnects the first and second transverse tracks, the rotating transverse track allows for passage of the support rollers, thereby preventing interference between the support rollers transported on the roller replacement track mechanism and the transverse track mechanism.

[0026] Furthermore, during the use of the rotating and transverse track, the rotating and transverse track needs to be connected to the first and second transverse tracks, so that the rotating and transverse track has a larger track span. When the transverse roller device moves onto the rotating and transverse track, the weight of the transverse roller device and the roller body placed on the transverse roller device will all act on the rotating and transverse track, thereby putting a large pressure on the rotating and transverse track, and the rotating and transverse track is prone to deflection, resulting in a height difference between the rotating and transverse track and the first and second transverse tracks on both sides, thereby affecting the operating stability of the transverse roller device on the rotating and transverse track.

[0027] In order to avoid the above problems, the transverse track mechanism described in the embodiment of the present invention also includes a track support structure. By arranging the track support structure between the first transverse track and the second transverse track, when the rotating transverse track connects the first transverse track and the second transverse track, the track support structure can support the rotating transverse track. By increasing the number of support points of the rotating transverse track, the track span of the rotating transverse track is reduced, and the deflection deformation of the rotating transverse track is reduced, so that the rotating transverse track can better connect the first transverse track and the second transverse track, thereby improving the operating stability of the transverse roller device on the rotating transverse track.

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe 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 the embodiments. 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.

[0050] Please refer to Figures 1 to 6 In an embodiment of the utility model, a transverse track mechanism is provided, including: a first transverse track 1 and a second transverse track 2 arranged at intervals; a rotating transverse track 3 arranged between the first transverse track 1 and the second transverse track 2, and the rotating transverse track 3 controllably connects the first transverse track 1 and the second transverse track 2; and a track support structure 4, arranged between the first transverse track 1 and the second transverse track 2, and when the rotating transverse track 3 is in a state of connecting the first transverse track 1 and the second transverse track 2, the track support structure 4 can support the rotating transverse track 3.

[0051] In general, when the transverse track mechanism described in the embodiment of the present invention is in use, the first transverse track 1 and the second transverse track 2 are spaced apart in the same direction, and the rotating transverse track 3 controllably connects the first transverse track 1 and the second transverse track 2. When the rotating transverse track 3 connects the first transverse track 1 and the second transverse track 2, the transverse roller device 6 can be moved along the transverse track mechanism to replace the rollers. When the rotating transverse track 3 disconnects the first transverse track 1 and the second transverse track 2, the rotating transverse track 3 clears a passage for the support rollers to pass through, thereby preventing interference between the support rollers and the transverse track mechanism. By setting the track support structure 4 between the first transverse track 1 and the second transverse track 2, when the rotating transverse track 3 connects the first transverse track 1 and the second transverse track 2, the track support structure 4 can support the rotating transverse track 3. By increasing the number of support points of the rotating transverse track 3, the track span of the rotating transverse track 3 is reduced, thereby reducing the disturbance deformation of the rotating transverse track 3, so that the rotating transverse track 3 can better connect the first transverse track 1 and the second transverse track 2, thereby improving the operating stability of the transverse roller device 6 on the rotating transverse track 3.

[0052] In the embodiments of the present invention, refer to Figures 1 to 3 The track support structure 4 includes a first support part 41 arranged on the first transverse track 1, and a second support part 42 arranged on the second transverse track 2. When the rotating transverse track 3 is in a state of connecting the first transverse track 1 and the second transverse track 2, the two ends of the rotating transverse track 3 are respectively overlapped on the first support part 41 and the second support part 42.

[0053] By means of a first support part 41 arranged on the first transverse rail 1 and a second support part 42 arranged on the second transverse rail 2, the two ends of the rotating transverse rail 3 can be supported. On the one hand, the deformation of the rotating transverse rail 3 can be reduced. On the other hand, the rotating transverse rail 3 can be better connected with the first transverse rail 1 and the second transverse rail 2, thereby improving the stability of the transverse roller device 6 in the movement between the first transverse rail 1, the rotating transverse rail 3 and the second transverse rail 2.

[0054] Specifically, a support surface can be provided on each of the first support portion 41 and the second support portion 42 , and the support surface can be provided in a horizontal direction. The support surface has a larger support range and can better support both ends of the rotating and transverse track 3 .

[0055] Furthermore, overlapping end surfaces that match the support surface can be set at both ends of the rotating and lateral movement track 3, so that the rotating and lateral movement track 3 can form a surface match with the support surface through the overlapping end surfaces, thereby improving the support performance.

[0056] In the embodiments of the present invention, refer to Figure 4 The track support structure 4 also includes at least one third support part 43 arranged between the first support part 41 and the second support part 42. When the rotating and transverse track 3 is in a state of connecting the first and second transverse track 1 and 2, the rotating and transverse track 3 is overlapped on the third support part 43.

[0057] By arranging at least one third support portion 43 between the first support portion 41 and the second support portion 42, the middle portion of the rotating and transverse track 3 can be supported by the third support portion 43, thereby reducing the track span of the rotating and transverse track 3 and further reducing the deflection deformation suffered by the rotating and transverse track 3.

[0058] Specifically, a support that cooperates with the third support portion 43 can be provided on the rotating and traversing track 3. The support can be detachably mounted on the rotating and traversing track 3. When the support becomes worn, it can be removed and replaced. Of course, the support can also be fixedly mounted on the rotating and traversing track 3, which is not a limitation here.

[0059] In an embodiment of the present utility model, a roller changing rail mechanism 5 is provided below the rotating and transverse moving rail 3, and the roller changing rail mechanism 5 includes two parallel roller changing guide rails 51. The third support portion 43 is composed of the roller changing guide rails 51. When the rotating and transverse moving rail 3 is in a state of connecting the first and second transverse moving rails 1 and 2, the rotating and transverse moving rail 3 is overlapped on the two roller changing guide rails 51.

[0060] When the roller changing track mechanism 5 is in use, the roller changing vehicle can be movably arranged on the roller changing guide rail 51 , and the roller changing vehicle can move along the roller changing guide rail 51 to transport new roller bodies or old roller bodies.

[0061] Specifically, the roller changing track mechanism 5 can be arranged to intersect perpendicularly with the transverse roller mechanism, so that the roller changing guide rail 51 can pass through the rotating transverse track 3. When the roller changing vehicle transports the support rollers, the rotating transverse track 3 can be adjusted to avoid interference between the support rollers and the transverse roller mechanism, thereby improving the convenience of roller transportation.

[0062] Among them, the roller changing guide rail 51 can be set below the rotating transverse track 3. When the rotating transverse track 3 is in a state of connecting the first transverse track 1 and the second transverse track 2, the rotating transverse track 3 can be overlapped on the roller changing guide rail 51 through the support.

[0063] In the embodiments of the present invention, refer to Figure 5 and Figure 6The rotating and transverse track 3 includes two rotating and transverse guide rails 31 arranged side by side, one of which is hinged to the first transverse track 1, and the other is hinged to the second transverse track 2.

[0064] By hingedly connecting the two rotating transverse guide rails 31 to the first transverse rail 1 and the second transverse rail 2 respectively, the stress generated by the rotating transverse guide rail 31 during installation and use can be avoided from being concentrated on the transverse rail on the same side, thereby improving the use stability of the rotating transverse rail 3.

[0065] Of course, designers can also hinge the two rotating transverse guide rails 31 to the first transverse rail 1 or the second transverse rail 2 at the same time, and there is no limitation here.

[0066] In an embodiment of the present utility model, the transverse track mechanism also includes a rotation drive device 32, which is connected to the rotating transverse track 3. The rotation drive device 32 is used to push the rotating transverse track 3 to controllably connect the first transverse track 1 and the second transverse track 2.

[0067] Specifically, the rotation drive device 32 may include a telescopic device, such as a hydraulic cylinder or a pneumatic cylinder, which drives the rotating and transverse guide rail 31 to rotate about a hinge point via a telescopic rod. By activating the telescopic device, the rotating and transverse guide rail 31 is driven to rotate about a hinge point, thereby connecting or disconnecting the rotating and transverse guide rail 31.

[0068] Please refer to Figures 7 to 10 The present invention also provides a transverse roller changing device, comprising the transverse track mechanism described in the aforementioned embodiment and a transverse roller device 6, wherein the transverse roller device 6 is movably mounted on the transverse track mechanism. The specific structure, operating principle, and beneficial effects of the transverse track mechanism are the same as those described in the aforementioned embodiment and will not be further elaborated here. The transverse roller changing device, through the transverse track mechanism, can improve the operational stability of the transverse roller device 6.

[0069] In an embodiment of the present utility model, the transverse roller device 6 includes a first transverse roller vehicle 61 and a second transverse roller vehicle 62. The first transverse roller vehicle 61 and the second transverse roller vehicle 62 can both be movably arranged on the transverse track mechanism.

[0070] Specifically, a roller platform can be provided on the first transverse roller vehicle 61 and the second transverse roller vehicle 62, and the roller body can be placed on the roller platform for transportation. Of course, the designer can also provide a roller bracket on the roller platform according to the use needs, and use the roller bracket to place or replace the roller body.

[0071] Furthermore, the first transverse roller trolley 61 is movably disposed on the first transverse rail 1, and the second transverse roller trolley 62 is movably disposed on the second transverse rail 2. When the rotating transverse rail 3 connects the first transverse rail 1 and the second transverse rail 2, the first transverse roller trolley 61 can move along the first transverse rail 1 and the rotating transverse rail 3 to the second transverse rail 2, and the second transverse roller trolley 62 can move along the second transverse rail 2 and the rotating transverse rail 3 to the first transverse rail 1. Designers can control the movement modes of the first transverse roller trolley 61 and the second transverse roller trolley 62 according to usage needs, and no specific restrictions are imposed here.

[0072] Further, in the embodiments of the present invention, Figure 9 and Figure 10 The transverse roller changing device also includes a guide structure 7, which includes a first guide slide 71 arranged on the first transverse roller trolley 61, a second guide slide 72 arranged on the second transverse roller trolley 62, and a transverse guide slide 73 arranged on the transverse rail mechanism. The first transverse roller trolley 61 and the transverse rail mechanism are slidably matched with each other through the first guide slide 71 and the transverse guide slide 73, and the second transverse roller trolley 62 and the transverse rail mechanism are slidably matched with each other through the second guide slide 72 and the transverse guide slide 73.

[0073] Specifically, a first guide slide 71 may be provided at the bottom of the first transverse roller trolley 61. The first transverse roller trolley 61 slidably cooperates with a transverse guide slide 73 provided on the transverse track mechanism via the first guide slide 71, so that the first transverse roller trolley 61 can move along the setting direction of the transverse track mechanism. A second guide slide 72 may be provided at the bottom of the second transverse roller trolley 62. The second transverse roller trolley 62 slidably cooperates with a transverse guide slide 73 provided on the transverse track mechanism via the second guide slide 72, so that the second transverse roller trolley 62 can also move along the setting direction of the transverse track mechanism.

[0074] Of course, as another alternative arrangement of the guide structure 7, a fixed track platform 74 can also be provided. The fixed track platform 74 is provided along the direction of the transverse track mechanism and above the transverse track mechanism. The transverse guide slide 73 can be provided on the fixed track platform 74. The first transverse roller vehicle 61 is connected to the transverse guide slide 73 on the fixed track platform 74 via the first guide slide 71, and the second transverse roller vehicle 62 is connected to the transverse guide slide 73 on the fixed track platform 74 via the second guide slide 72. Of course, designers can also provide the transverse guide slide 73 at other locations or structures, which is not limited here.

[0075] By cooperating with the first guide slide 71, the second guide slide 72 and the transverse guide slide 73, the first transverse roller trolley 61 and the second transverse roller trolley 62 can move along the preset direction, which also improves the stability of the first transverse roller trolley 61 and the second transverse roller trolley 62 moving along the transverse track mechanism.

[0076] In an embodiment of the present utility model, the transverse roller changing device also includes a first transverse driving device 63 and a second transverse driving device 64. The first transverse driving device 63 is connected to the first transverse roller vehicle 61, and the second transverse driving device 64 is connected to the second transverse roller vehicle 62.

[0077] Specifically, the first transverse driving device 63 and the second transverse driving device 64 can both adopt telescopic devices, such as hydraulic cylinders or air cylinders. The telescopic devices are connected to the corresponding first transverse roller trolley 61 and second transverse roller trolley 62 through telescopic rods, and are used to push the first transverse roller trolley 61 and second transverse roller trolley 62 to move along the transverse track mechanism.

[0078] In an embodiment of the present invention, a first connecting portion 65 is provided on the first transverse roller vehicle 61 , and a second connecting portion 66 is provided on the second transverse roller vehicle 62 . The first connecting portion 65 and the second connecting portion 66 are detachably connected to each other.

[0079] Specifically, the first connecting portion 65 and the second connecting portion 66 can be detachably connected by bolts. Of course, the first connecting portion 65 and the second connecting portion 66 can also be detachably connected by snap fasteners, which is not limited here.

[0080] By connecting the first transverse roller trolley 61 with the second transverse roller trolley 62, the first transverse roller trolley 61 and the second transverse roller trolley 62 can move synchronously, so that only the first transverse roller trolley 61 or the second transverse roller trolley 62 needs to be pushed to push the first transverse roller trolley 61 and the second transverse roller trolley 62 to move synchronously along the transverse rail mechanism for placing or transporting the roller body.

[0081] In the embodiments of the present invention, refer to Figure 8 、 Figure 9 and Figure 10The transverse roller changing device also includes a transverse track cover structure 8, and the transverse track cover structure 8 includes a first telescopic cover 81 and a second telescopic cover 82; one end of the first telescopic cover 81 is fixed, and the other end of the first telescopic cover 81 is connected to the first transverse roller trolley 61. Driven by the first transverse roller trolley 61, the first telescopic cover 81 can telescopically cover the first transverse track 1; one end of the second telescopic cover 82 is fixed, and the other end of the second telescopic cover 82 is connected to the second transverse roller trolley 62. Driven by the second transverse roller trolley 62, the second telescopic cover 82 can telescopically cover the second transverse track 2.

[0082] Specifically, one end of the first telescopic cover plate 81 is fixedly disposed at an end of the first transverse track 1 away from the second transverse track 2, and the other end of the first telescopic cover plate 81 is connected to the first transverse roller trolley 61. When the first transverse roller trolley 61 moves along the transverse track mechanism, the first transverse roller trolley 61 can drive the first telescopic cover plate 81 to cover the first transverse track 1. One end of the second telescopic cover plate 82 is fixedly disposed at an end of the second transverse track 2 away from the first transverse track 1, and the other end of the second telescopic cover plate 82 is connected to the second transverse roller trolley 62. When the second transverse roller trolley 62 moves along the transverse track mechanism, the second transverse roller trolley 62 can drive the second telescopic cover plate 82 to cover the second transverse track 2.

[0083] The first telescopic cover plate 81 and the second telescopic cover plate 82 can protect the first transverse track 1 and the second transverse track 2, thereby preventing foreign matter from entering the transverse track mechanism and affecting the operating stability of the first transverse roller trolley 61 and the second transverse roller trolley 62. Furthermore, the first telescopic cover plate 81 and the second telescopic cover plate 82 can also be used as an operating platform, which is not limited here.
