[0001] The invention belongs to the technical field of a large-span frame movable rolling mill, and in particular relates to a large-span frame movable rolling mill drag chain device. Background Art

[0002] When a large steel frame mobile rolling mill needs to open the frame for changing the roll system, the distance of opening the mobile frame on the operating side is long, and the pipelines required for the equipment to work need to be connected to the pipelines of the fixed frame on the transmission side through a drag chain. When the drag chain is working, the supporting force cannot support the weight of the drag chain and the weight of many connected pipelines, so the work of the mobile rolling mill is affected and cannot work, which becomes an urgent problem to be solved. Summary of the invention

[0003] In view of this, the present invention proposes a large-span frame movable rolling mill drag chain device to solve the problem that the drag chain's supporting force cannot support the total weight of the drag chain and numerous connecting pipelines during operation, so that the operation of the movable rolling mill is affected and cannot work.

[0004] To achieve the above object, the technical solution created by the present invention is implemented as follows:

[0005] A large-span frame movable rolling mill drag chain device comprises a first slide rail, a second slide rail, a support frame, and a drag chain. The first slide rail is installed on the fixed frame platform on the transmission side, and the second slide rail is installed on the mobile frame platform on the operating side. The first slide rail and the second slide rail are arranged opposite to each other, and both ends of the support frame are connected with drag chains. The end of the drag chain away from the support frame is arranged at the bottom of the support frame, and the two drag chains extend inward away from one end of the support frame. One end of one drag chain away from the support frame is fixedly connected to the fixed frame platform on the transmission side, and the other end of the drag chain away from the support frame is fixedly connected to the mobile frame platform on the operating side. Rollers are installed on both ends of the support frame through the mounting frame, and the support frame is slidably connected to the first slide rail and the second slide rail respectively through the rollers.

[0006] Furthermore, the support frame includes a connecting plate and a bearing plate. There are two connecting plates. The bearing plate is fixed between the two connecting plates. Both ends of the connecting plates are connected to a tow chain.

[0007] Furthermore, the bottom of each connecting plate extends downward to form a first reinforcing plate.

[0008] Furthermore, a plurality of strip-shaped through holes are formed on the carrying plate, and the strip-shaped through holes are arranged perpendicular to the length direction of the carrying plate.

[0009] Furthermore, the mounting frame includes a dovetail plate, a fixed plate, and a second mounting plate. There are two dovetail plates, which are fixedly connected by a fixed block. The top of the fixed block is fixedly connected to the second mounting plate. A plurality of fixed plates are fixed to the second mounting plate. One side of the fixed plate perpendicular to the second mounting plate is fixedly connected to the end of the support frame. A roller is rotatably connected between the bottoms of the two dovetail plates.

[0010] A second reinforcing plate is connected between two oppositely arranged mounting frames.

[0011] Furthermore, the first slide rail and the second rail each include a side plate, a support plate, and a bottom plate. There are two side plates, a support plate is fixed on one side of each side plate, and a bottom plate is fixed on the bottom of the support plate. The two side plates are arranged opposite to each other. One end of the two side plates of the first slide rail is fixedly connected to the fixed frame platform on the transmission side through the bottom plate, and the other end extends to the mobile frame platform on the operation side. One end of the two side plates of the second rail is fixedly connected to the mobile frame platform on the operation side through the bottom plate, and the other end extends to the fixed frame platform on the transmission side. The rollers are arranged on the side plates and are slidably connected to the side plates.

[0012] Furthermore, the support plate of the first slide rail is arranged outward, the support plate of the second slide rail is arranged inward, the distance between the two side plates of the first slide rail is greater than the distance between the two side plates of the second slide rail, and a gap is arranged between the second slide rail and the first slide rail.

[0013] Furthermore, a second limit plate is fixed to the bottom of the dovetail plate, a first limit plate is fixed to the top of the support plate along the length direction of the track, the second limit plate is provided with a slot corresponding to the first limit plate, one side of the first limit plate is fixedly connected to the side plate, and the other side is arranged in the slot, and a gap is set between the first limit plate and the second limit plate.

[0014] Furthermore, the second limit plate located above the first slide rail is arranged on the outer side of the dovetail plate, and the second limit plate located above the second rail is arranged on the inner side of the dovetail plate.

[0015] Furthermore, a stopper for limiting the position of the roller is fixed to one end of the first slide rail and the second rail close to the support frame.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] (1) When the drag chain is working, the load-bearing plate in the middle position is a straight section, and the drag chain does not bend. A roller mounting frame is installed under the support frame and a track installed on the platform to bear the weight of the support frame and the weight of the pipeline, effectively increasing the load-bearing capacity of the drag chain device.

[0018] (2) The second reinforcing plate supports and reinforces the support frame, so that the support frame has a greater bearing capacity.

[0019] (3) The arrangement of the strip-shaped through holes reduces the weight of the support frame and alleviates the burden on the slide rail.

[0020] (4) The second rail can extend into the inner side of the first rail as the operating side mobile rack platform moves, so that when the drag chain is at the minimum distance between the operating side platform and the transmission side platform, the first rail and the second rail extend into each other's platform without interference, thereby avoiding affecting the operation of the drag chain and the support frame.

[0021] (5) The first limit plate and the second limit plate prevent the drag chain from falling off the track and tipping over when sliding at high altitude. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0033] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0034] like Figure 2 , Figure 3 , Figure 5 As shown, a large-span frame movable rolling mill drag chain device includes a first slide rail 4, a second slide rail 5, a support frame 1, and a drag chain 11. The first slide rail 4 is installed on the fixed frame platform 7 on the transmission side, and the second slide rail 5 is installed on the movable frame platform 8 on the operating side. The first slide rail 4 and the second slide rail 5 are arranged opposite to each other, and both ends of the support frame 1 are connected with drag chains 11. The end of the drag chain 11 away from the support frame 1 is arranged at the bottom of the support frame 1, and the two drag chains 11 extend inward away from one end of the support frame 1, one end of the drag chain 11 away from the support frame 1 is fixedly connected to the fixed frame platform 7 on the transmission side, and the other end of the drag chain 11 away from the support frame 1 is fixedly connected to the movable frame platform 8 on the operating side, and rollers 2 are installed on both ends of the support frame 1 through the mounting frame 3, and the support frame 1 is slidingly connected to the first slide rail 4 and the second slide rail 5 through the rollers 2.

[0035] like Figure 1 to Figure 2As shown, the support frame 1 includes a connecting plate 12 and a bearing plate 13 . There are two connecting plates 12 . The bearing plate 13 is fixed between the two connecting plates 12 . Both ends of the connecting plates 12 are connected to a tow chain 11 .

[0036] When the drag chain 11 is working, the load-bearing plate 13 in the middle position is a straight section, and the drag chain 11 does not bend. The roller 2 mounting frame 3 installed below the support frame 1 and the track installed on the platform together bear the weight of the support frame 1 and the weight of the pipeline, effectively increasing the bearing capacity of the drag chain 11. In the middle straight section of the traditional drag chain 11 device, due to the excessive weight of the drag chain 11 and the pipeline, the cantilever auxiliary wheel support frame 1 cannot meet the working needs and collapses, making the drag chain 11 unable to work normally, affecting the roller replacement work of the equipment.

[0037] like Figure 1 to Figure 2 As shown, the bottom of each connecting plate 12 extends downward to form a first reinforcing plate 16 .

[0038] like Figure 1 As shown, a plurality of strip-shaped through holes 14 are formed on the bearing plate 13, and the strip-shaped through holes 14 are arranged perpendicular to the length direction of the bearing plate 13. The arrangement of the strip-shaped through holes 14 reduces the weight of the support frame 1 and the burden of the slide rail.

[0039] like Figure 3 to Figure 4 As shown, the mounting frame 3 includes a dovetail plate 32, a fixed plate 31, and a second mounting plate 34. There are two dovetail plates 32, and the two dovetail plates 32 are fixedly connected by a fixed block 33. The top of the fixed block 33 is fixedly connected to the second mounting plate 34. A plurality of fixed plates 31 are fixed on the second mounting plate 34. The side of the fixed plate 31 perpendicular to the second mounting plate 34 is fixedly connected to the end of the support frame 1. A roller 2 is rotatably connected between the bottoms of the two dovetail plates 32; a second reinforcing plate 17 is connected between the two oppositely arranged mounting frames 3.

[0040] like Figures 1 to 3 As shown, the first slide rail 4 and the second slide rail 5 both include side plates 53, support plates 54, and bottom plates 55. There are two side plates 53, and a support plate 54 is fixed on one side of each side plate 53. A bottom plate 55 is fixed on the bottom of the support plate 54. The two side plates 53 are arranged opposite to each other. One end of the two side plates 53 of the first slide rail 4 is fixedly connected to the fixed frame platform 7 on the transmission side through the bottom plate 55, and the other end extends to the movable frame platform 8 on the operation side. One end of the two side plates 53 of the second slide rail 5 is fixedly connected to the movable frame platform 8 on the operation side through the bottom plate 55, and the other end extends to the fixed frame platform 7 on the transmission side. The roller 2 is arranged on the side plate 53 and is slidably connected to the side plate 53.

[0041] like Figure 3As shown, the support plate 54 of the first slide rail 4 is arranged outward, and the support plate 54 of the second slide rail 5 is arranged inward, the distance between the two side plates 53 of the first slide rail 4 is greater than the distance between the two side plates 53 of the second slide rail 5, and the second slide rail 5 is arranged with a gap between the first slide rail 4. The second slide rail 5 can extend into the inner side of the first slide rail 4 with the movement of the operating side mobile rack platform 8, so that when the drag chain 11 is at the minimum distance between the operating side and the transmission side platform, the first slide rail 4 and the second slide rail 5 extend into each other's platform without interference, thereby avoiding affecting the operation of the drag chain 11 and the support frame 1.

[0042] The first slide rail 4 on the operating side platform and the second slide rail 5 on the transmission side platform are installed in opposite directions, and the opposite sides of the rails are flat, ensuring that the rails do not interfere with each other when the platform has the minimum working distance. The installation positions of the mounting frame 32 installed under the support frame 1 and the transmission side support mounting frame 3 are determined according to the spacing of the rails.

[0043] like Figure 1 , Figure 3 As shown, a second limiting plate 6 is also fixed to the bottom of the dovetail plate 32, a first limiting plate 52 is fixed to the top of the support plate 54 along the length direction of the track, and a slot 61 corresponding to the first limiting plate 52 is opened on the second limiting plate 6. One side of the first limiting plate 52 is fixedly connected to the side plate 53, and the other side is arranged in the slot 61. A gap is set between the first limiting plate 52 and the second limiting plate 6 to prevent the drag chain 11 from deviating from the track and tipping over when sliding at high altitude.

[0044] like Figure 1 , Figure 3 As shown, the second limiting plate 6 located above the first slide rail 4 is arranged on the outer side of the dovetail plate 32 , and the second limiting plate 6 located above the second slide rail 5 is arranged on the inner side of the dovetail plate 32 .

[0045] like Figure 1 , Figure 4 As shown, a stopper 51 for limiting the position of the roller 2 is fixed to one end of the first slide rail 4 and the second slide rail 5 close to the support frame 1 .

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
