Description

Technical Field

[0001] This utility model relates to the technical field of steel rolling production equipment, and specifically to a novel steel unloading mechanism for a cooling bed. Background Technology

[0002] After being cooled by the walking gear rack cooling bed, the straight bars are arranged in rows by the steel chain and then transferred to the cooling bed output roller conveyor by the cooling bed unloading mechanism. The cooling bed output roller conveyor then transports the straight bars to the fixed-length cold shearing machine for cutting.

[0003] like Figure 1 As shown, the current new type of steel unloading mechanism for the cooling bed is driven by a hydraulic cylinder 20. The swing link 10 raises the steel support trolley 121, which lifts the rows of bars and the bars leave the steel support chain. After the steel support trolley moves to the output roller conveyor of the cooling bed, the hydraulic cylinder retracts and drives the swing link to lower the steel support trolley, placing the rows of bars on the output roller conveyor of the cooling bed.

[0004] Because existing cooling bed unloading mechanisms use multiple hydraulic cylinders, typically one cylinder per six-meter group along with corresponding swing linkages and steel-supporting trolleys, the hydraulic system needs to consider synchronization. However, synchronization is difficult to adjust, easily leading to poor synchronization in the lifting and lowering of the steel-supporting trolley. This results in wavy lines on the bars on the trolley, and at the lowest point, the bars may even scrape against the roller conveyor baffles, causing steel irregularities. Furthermore, the hydraulic cylinders are prone to damage and oil leaks under rolling conditions, affecting synchronization. The hydraulic cylinders are located under the trolley crossbeam of the entire cooling bed unloading mechanism, making maintenance and replacement difficult.

[0005] Therefore, a new type of cold bed unloading mechanism is needed, which can lift and move rows of bars, has good synchronization of lifting and lowering of the steel-supporting trolley, and eliminates the need for a hydraulic system, thus solving the disadvantages of hydraulic cylinder oil leakage and troublesome maintenance and replacement.

[0032] This utility model provides a novel steel unloading mechanism for a cooling bed, overcoming the shortcomings of the prior art where the steel unloading mechanism for a cooling bed uses a hydraulic cylinder drive, the synchronization of the hydraulic cylinder is difficult to adjust, the hydraulic cylinder is prone to damage and oil leakage affecting synchronization, and the maintenance and replacement of the hydraulic cylinder is troublesome; it achieves the technical effect of eliminating the large and complex hydraulic system and using a pure mechanical structure with a connecting rod transmission assembly and an eccentric wheel drive assembly, which is novel and simple in structure, has good lifting synchronization, and requires less maintenance.

[0033] The overall concept of the technical solution of this utility model embodiment is as follows:

[0034] A purely mechanical structure with a linkage transmission assembly and an eccentric wheel drive assembly is added. The lifting drive spindle rotates the eccentric wheel 180°, raising the roller. With the help of the first swing arm, the second swing arm, and the connecting rod, the left and right sides of the trolley track rise synchronously, and the trolley track disengages from the first and second columns. At the same time, the steel-supporting cantilever of the steel-supporting trolley lifts the rows of bars. Then, the steel-supporting cantilever moves along the trolley track with the steel-supporting trolley, realizing the movement of the rows of bars. The lifting drive spindle rotates the eccentric wheel another 180°, and the roller descends due to gravity. With the help of the first swing arm, the second swing arm, and the connecting rod, the left and right sides of the trolley track descend synchronously. The trolley track is placed on the first and second columns, and the rows of bars, the steel-supporting cantilever, and the steel-supporting trolley descend simultaneously with the trolley track.

[0035] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0036] See Figures 1 to 11 The preferred embodiment of this utility model.

[0037] A novel cold bed unloading mechanism includes a cold bed unloading device 1 and a lifting drive spindle 2. The cold bed unloading device 1 includes a support assembly 11, a trolley transport assembly 12, a linkage transmission assembly 13, and an eccentric wheel drive assembly 14.

[0038] The support assembly 11 includes a bracket 111 and a first column 112, a second column 113 and a base 114 fixedly disposed on the bracket 111;

[0039] The trolley transport assembly 12 includes a steel-supporting trolley 121 and a trolley track 122. The steel-supporting trolley 121 is movably connected to the trolley track 122. The steel-supporting trolley 121 has a steel-supporting cantilever 123 with anti-slip texture. The left and right parts of the trolley track 122 are located above the first column 112 and the second column 113, respectively.

[0040] The linkage transmission assembly 13 includes a first swing arm 131, a second swing arm 132, a connecting rod 133, and a roller 134. The middle part of the first swing arm 131 is hinged to the first column 112, the upper part of the first swing arm 131 is hinged to the right part of the trolley track 122, and the lower part of the first swing arm 131 is hinged to the right part of the connecting rod 133. The middle part of the second swing arm 132 is hinged to the second column 113, the upper part of the second swing arm 132 is hinged to the left part of the trolley track 122, and the lower part of the second swing arm 132 is hinged to the left part of the connecting rod 133. The roller 134 is mounted on the upper part of the first swing arm 131.

[0041] The eccentric wheel drive assembly 14 includes an eccentric wheel 141, a bearing 142, and a counterweight 143. The eccentric position hole of the eccentric wheel 141 is fixedly connected to the lifting drive spindle 2. The wheel surface of the eccentric wheel 141 is in contact with the wheel surface of the roller 134. The lifting drive spindle 2 is connected to the base 114 through the bearing 142. The counterweight 143 is fixedly mounted on the lifting drive spindle 2.

[0042] The beneficial effects of the above technical solution are that by adding a purely mechanical structure with a connecting rod transmission assembly 13 and an eccentric wheel drive assembly 14, combined with the steel support cantilever 123, the steel support trolley 121 can lift and move the rows of bars 9. The lifting and lowering synchronization of the steel support trolley 121 is good, and the hydraulic system is eliminated, solving the disadvantages of hydraulic cylinder oil leakage and troublesome maintenance and replacement. The anti-slip texture of the steel support cantilever 123 is conducive to stable transportation of bars 9. The lifting and lowering of the steel support trolley 121 is driven by an eccentric wheel 141, and the lifting drive main shaft 2 is equipped with a counterweight 143, which can reduce the off-center load of the eccentric wheel 141 on the lifting drive main shaft 2.

[0043] Furthermore, it also includes a transport drive spindle 3. The trolley transport assembly 12 further includes a drive sprocket 124, a driven sprocket 125, an auxiliary sprocket 126, and a chain 127. The drive sprocket 124 is fixedly connected to the transport drive spindle 3. The drive sprocket 124 is installed in the middle of the trolley track 122. The two driven sprockets 125 are respectively installed at the left and right ends of the trolley track 122. The two auxiliary sprockets 126 are respectively installed on the left and right sides of the drive sprocket 124. The chain 127 is wound around the drive sprocket 124, the driven sprocket 125, and the auxiliary sprocket 126. The chain 127 is also fixedly connected to the steel support trolley 121.

[0044] The beneficial effect of this technical solution is that the transport drive spindle 3 causes the drive sprocket 124 to rotate in the forward or reverse direction, and the steel support trolley 121 moves forward or backward through the chain 127; the transport drive spindle 3 is set below the steel support trolley 121 to avoid the transport drive spindle 3 interfering with the steel support chain and the output roller conveyor 8 of the cooling bed.

[0045] Furthermore, it also includes a first drive motor 4 and a second drive motor 5. The output shaft of the first drive motor 4 is connected to the transport drive main shaft 3 via a first coupling, and the output shaft of the second drive motor 5 is connected to the lifting drive main shaft 2 via a second coupling.

[0046] The beneficial effect of this technical solution is that the first drive motor 4 provides the power for the steel-carrying trolley 121 to move forward or backward, and the second drive motor 5 provides the power for the rotation of the eccentric wheel 141. Compared with the drive motor of the hydraulic pump connected to the hydraulic cylinder in the prior art, the second drive motor 5 has lower power and saves more energy.

[0047] Furthermore, the anti-slip texture is a toothed strip.

[0048] The beneficial effect of this technical solution is that the rack helps to improve the stability of the transferred bar.

[0049] Furthermore, the two steel unloading devices 1 on the cooling bed are arranged one in front of the other.

[0050] The beneficial effect of this technical solution is that the steel-supporting cantilever of the two cooling bed unloading devices respectively supports the front and rear ends of the row of bars, freeing up space in the middle of the bars and improving the stability of the bars.

[0051] Furthermore, the novel cooling bed unloading mechanism comprises multiple components, and the lifting drive spindles 2 of two adjacent novel cooling bed unloading mechanisms are connected by a clamp coupling 6, on which the counterweight 143 is welded. The counterweight 143 is a steel billet.

[0052] The beneficial effect of this technical solution is that the clamp coupling 6 and the lifting drive spindle 2 are detachable, realizing the detachability of the counterweight 143. According to the actual eccentric load of the eccentric wheel 141 on the lifting drive spindle 2, the corresponding counterweight 143 can be flexibly selected and installed on the lifting drive spindle 2 through the clamp coupling 6 for eccentric load compensation.

[0053] The working principle of this utility model is as follows:

[0054] The lifting drive spindle 2 causes the eccentric wheel 141 to rotate 180°, the eccentric wheel 141 lifts the roller 134, and the trolley track 122 is raised through the linkage transmission assembly 13. The trolley track 122 disengages from the first column 112 and the second column 113. The steel-supporting cantilever 123 of the steel-supporting trolley 121 also rises accordingly and supports the rows of bars 9 away from the steel chain 7. Then the steel-supporting trolley 121 moves to the position of the output roller conveyor 8 of the cooling bed. The lifting drive spindle 2 then causes the eccentric wheel 141 to rotate 180°, and the roller 134 follows the eccentric wheel 141 to descend. With the help of gravity, the trolley track 122 descends and is placed on the first column 112 and the second column 113. The steel-supporting cantilever 123 descends below the output roller conveyor 8 of the cooling bed, so that the rows of bars 9 fall on the output roller conveyor 8 of the cooling bed, and the bars 9 are separated from the steel-supporting cantilever 123. The steel trolley 121 returns to its initial position to await the next action cycle.

[0055] This utility model uses a purely mechanical structure with a linkage transmission assembly and an eccentric wheel drive assembly. The structure is novel and simple, and the lifting and lowering synchronization of the steel-supporting trolley is good, requiring less maintenance. It eliminates the need for a large and complex hydraulic system, avoiding the easy damage to hydraulic cylinders that could lead to oil leakage and affect synchronization, and avoiding the troublesome maintenance and replacement of hydraulic systems.
