Description

Technical Field

[0001] The utility model belongs to the technical field of steel production, and in particular relates to a manual auxiliary steel picking device installed on a roller table. Background Art

[0002] In the steel production process, burr steel and long-size steel picking are two important quality control links. However, in the actual production process, abnormal conditions such as burr steel and long size often appear on the roller. Traditional processing methods: (1) The picking of burr steel is completed by visual inspection and manual cleaning; (2) For long-size steel, the length of the steel is accurately measured using measuring tools (such as tape measures, laser rangefinders, etc.), and it is divided into qualified and unqualified products based on the measurement results. Unqualified products may be returned for reprocessing or treated as defective products. The above traditional processing methods often require multiple workers to work together to manually turn out the problematic steel bit by bit, which is not only inefficient, but also has certain safety risks. This not only increases the labor intensity of workers on the production line, but also seriously restricts the continuity and stability of the production line. It may also cause production accidents due to improper operation, thereby affecting the safe operation of the entire production line.

[0003] In response to the above problems, the industry has proposed some solutions. For example, some companies try to solve the problem of high temperature working environment for workers by optimizing roller design and increasing the length of roller to increase the time for picking burred steel. However, this method often requires a lot of money to transform equipment. In addition, some companies use machine vision technology to detect and process these problematic steels through automatic identification systems. Although this method improves processing efficiency to a certain extent, it has high requirements for technical equipment and operating environment, and the maintenance cost also increases accordingly.

[0004] Therefore, there is an urgent need for a new solution that can not only efficiently handle burred steel and long rulers on the roller table, but also reduce labor costs and safety risks. It can also effectively improve the appearance quality and performance of steel, thereby meeting customer needs and improving the competitiveness of enterprises. Utility Model Content

[0007] As a further explanation and limitation of the above technical solution, the support includes a right-angle plate and a constraint plate, and a mounting hole and two limit blocks are provided on the right-angle plate. The two limit blocks are distributed on both sides of the mounting hole, and the constraint plate is installed on the right-angle plate by bolts.

[0033] In order to further illustrate the technical solution of the utility model, the following Figures 1 to 7 , we further illustrate the utility model through five embodiments according to the on-site transformation implementation process. Embodiment 1

[0034] As attached Figures 1 to 2 As shown in Figures 6 to 7, a manual auxiliary steel lifting device installed on a roller conveyor has two supports 1 installed on the brackets on both sides of the roller conveyor 21, wherein the support 1 includes a right-angle plate 101 and a constraint plate 102, a mounting hole 103 and two limit blocks 104 are provided on the right-angle plate 101, and the two limit blocks 104 are distributed on both sides of the mounting hole 103, and the constraint plate 102 is installed on the right-angle plate 101 by bolts 105, and the constraint plate 102 ensures that the rotating shaft 2 placed in the mounting hole 103 has a rotation space under the limitation of the two limit blocks 104. Therefore, the rotating shaft 2 is rotatably arranged in the mounting holes 103 of the two right-angle plates 101, a plug-in hole 19 is provided at one end of the rotating shaft 2, and a plug-in block 20 corresponding to the plug-in hole 19 is provided at one end of the pull rod 4, and the pull rod 4 cooperates with the plug-in block 20 through the plug-in hole 19 to achieve a quick plug-in connection with the rotating shaft 2. A slide hole 5 is provided on the plate hook 3, and the plate hook 3 is slidably arranged on the rotating shaft 2 through the slide hole 5, and the hooking direction of the plate hook 3 faces the transportation direction of the burr or long-sized steel 22. A limit slide bar 6 is axially arranged on the rotating shaft 2, and a limit slot 7 connected to the limit slide bar 6 is provided on the plate hook 3, and the limit slot 7 is communicated with the slide hole 5. This design can ensure that the plate hook 3 can hook up the burr or long-sized steel 22 as the rotating shaft 2 rotates, and can also ensure that the plate hook 3 can achieve directional sliding along the axial direction of the rotating shaft 2. Embodiment 2

[0035] In order to adjust the horizontal position of the plate hook without affecting the rotation and hooking action of the plate hook, we added a combination of horizontal plate and wire rope. Figure 2 and 3As shown, an I-beam 9 is fixedly connected between the two right-angle plates 101, and a transverse plate 10 is slidably arranged in a groove on one side of the I-beam 9. The transverse plate 10 includes a base 1001 and two limit baffles 1002 fixed thereon, the plate hook 3 is embedded between the two limit baffles 1002, and each limit baffle 1002 is provided with an arc groove 1003 corresponding to the rotating shaft 2, and first rollers 1005 are respectively arranged on the upper and lower end surfaces of the base 1001, and a plurality of second rollers 1006 are arranged side by side on one side end surface of the base 1001, and the plurality of second rollers 1006 are arranged opposite to the limit baffle 1002, so as to ensure smooth lateral sliding of the base 1001; fixing rings 1004 are respectively arranged on both side end surfaces of the base 1001, so as to respectively connect the two ends of the wire rope 11.

[0036] In this embodiment, the plate hook 3 is embedded in the transverse plate 10 and rotates with the rotation of the rotating shaft 2. The on-site operator realizes the lateral movement of the transverse plate 10 through the wire rope 11, thereby driving the plate hook 3 to move horizontally synchronously and move it to the direction where the burr or long-sized steel 22 comes, so as to facilitate the subsequent hooking and selection action. Embodiment 3

[0037] In order to facilitate the on-site operators to adjust the transverse movement of the transverse plate in a fast and labor-saving manner, we add a hand-cranked adjustment mechanism to the solution of the second embodiment. Figure 2 As shown, the specific scheme is as follows: a steering pulley 12 and a driving pulley 13 are respectively provided at both ends of the I-beam 9, a hand crank 14 is provided on the driving pulley 13, one end of the steel wire rope 11 is fixed on one side of the transverse plate 10, and the other end of the steel wire rope 11 is successively passed around the steering pulley 12 and the driving pulley 13 and fixed on the other side of the transverse plate 10, forming a hand crank adjustment mechanism for adjusting the lateral movement of the transverse plate 10. Embodiment 4

[0038] In the above-mentioned embodiments 2 and 3, the transverse plate is manually moved by wire rope traction. In order to ensure the transmission efficiency of the wire rope traction, we have taken the tension pulley measure to ensure that the wire rope is in a highly tensioned state, further ensuring the transmission efficiency of the wire rope. Figure 4 and 5 As shown, its implementation method is as follows: two nuts and screws 15 are arranged on the other side of the I-beam 9, and a mounting plate 16 is passed through both of them, a tensioning pulley 18 is arranged on the mounting plate 16, and a tensioning spring 17 is arranged on each nut and screw 15, and the tensioning spring 17 is located between the I-beam 9 and the mounting plate 16. The steel wire rope 11 passes around the tensioning pulley 18 and is kept in a tensioned state under the joint action of the two tensioning springs 17. Embodiment 5

[0039] In order to prevent the lateral plate from hitting the support during the lateral movement, thereby causing a slipping safety accident. Figure 2 As shown, we respectively set a retaining ring plate 8 at both ends of the rotating shaft 2, and the two retaining ring plates 8 are set between the two right-angle plates 101, and both are used to prevent the rotating shaft 2 from sliding off the support 1. The limiting slide bar 6 is distributed between the two retaining ring plates 8 to prevent the plate hook 3 from sliding off the rotating shaft 2.

[0040] Operation method of selecting abnormal steel: 1. Observation and judgment: The on-site operator closely observes the transportation of steel beside the roller, paying special attention to burred steel or long-sized steel. Once an abnormal situation is found, immediately determine the position of the abnormal steel to be selected on the roller. 2. Lateral adjustment: The operator drives the wire rope through the hand crank to adjust the position of the lateral plate. The plate hook in the lateral plate moves with the movement of the lateral plate to ensure that the plate hook moves to the selection position. 3. Pause the roller: When the abnormal steel is transported to the vicinity of the plate hook, the operator pauses the operation of the roller to ensure the accurate positioning of the steel. 4. Hook up the steel: The operator aligns the plate hook with the abnormal steel by pulling the lever, and then pulls the lever to make the plate hook hook up the abnormal steel. 5. Continue to run the roller: After the abnormal steel is successfully hooked up, the operator restarts the roller to select the abnormal steel.

[0041] The utility model adopts a combination of a transverse plate and a steel wire rope, and realizes a fast and labor-saving adjustment of the transverse plate through a hand crank. This design not only ensures that the plate hook can smoothly hook up abnormal steel, but also avoids the problem of requiring a lot of manpower and time in the traditional method. In addition, through the design of the tension pulley and the nut screw, the transmission efficiency of the steel wire rope is ensured, and the efficiency of the entire operation process is improved.

[0042] The above shows and describes the main features and advantages of the utility model. For those skilled in the art, it is obvious that the specific implementation of the utility model is not limited to the details of the above exemplary embodiments, and the creative ideas and design ideas of the utility model can be realized in other specific forms without departing from the spirit or basic features of the utility model, which should be equivalent to the protection scope disclosed in the technical solution of the utility model.

The scope of the utility model is limited by the attached claims rather than the above description, so it is intended to include all changes that fall within the meaning and scope of the equivalent elements of the claims in the utility model.
