Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe processing, specifically a steel pushing device that can improve sawing efficiency. Background Technology

[0002] Abrasive wheel saws are commonly used equipment in metallurgical bar rolling processing units. They are used to cut produced bars into segments of the required length using a sizing machine. On-site, depending on order requirements, there may be situations with small furnace numbers, resulting in only one or a few steel bars. The sawing process is lengthy, with long waiting times. The frequency of using multiple-length and single-length saws is the same, leading to energy waste and low production efficiency. On-site manual repositioning of the steel bars is necessary to maintain production rhythm, which is dangerous, labor-intensive, and time-consuming.

[0003] The biggest problems with moving steel are cost-effectiveness, safety, and production efficiency. Manually moving steel is costly, requiring approximately two people and not working continuously, making the position unprofitable. Manually pushing steel poses a high safety risk, as it is close to rotating parts such as roller conveyors and involves high temperatures and other hazards. Workers' mental state and other factors can also lead to accidents. Manually pushing steel is inefficient, with the largest steel diameter being 130mm and the total length 27m, resulting in extremely high labor intensity and low efficiency for workers.

[0004] To address the aforementioned problems, a steel pushing device for improving sawing efficiency is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a steel pushing device that improves sawing efficiency, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel pushing device for improving sawing efficiency, comprising a support, a pusher head, a receiving platform, and a hydraulic cylinder. The support consists of a base plate, a first side plate, and a second side plate, wherein the first side plate and the second side plate are arranged along a first direction and are respectively fixedly connected to the base plate. The base plate, the first side plate, and the second side plate form a groove, which is used to accommodate the hydraulic cylinder. The fixed end of the hydraulic cylinder is installed on the support. The groove formed by the base plate, the first side plate, and the second side plate ensures that the pusher head can move linearly back and forth in the groove, thereby ensuring that the steel pipe pushed by the pusher head can move linearly.

[0007] The receiving platform is slidably disposed on the side of the first and second side plates away from the bottom plate along the extension direction of the groove, covering at least a portion of the top opening of the groove, thereby ensuring that iron scale and sawdust generated during the sawing process of the steel pipe fall into the groove, thus affecting the sliding of the push head within the groove; the surface of the receiving platform away from the bottom plate forms a bearing surface, providing a plane capable of bearing the steel pipe to be pushed; the push head is fixed to the receiving platform, with one end protruding from the bearing surface and the other end extending into the groove and connected to the telescopic end of the hydraulic cylinder; ensuring that when the hydraulic cylinder drives the push head to move, the bearing platform can move synchronously with the push head, thereby preventing iron scale and sawdust from falling into the groove during the pushing of the steel pipe.

[0008] Furthermore, the fixed end of the hydraulic cylinder is mounted between the first side plate and the second side plate via a connecting shaft, thereby ensuring a more stable connection between the hydraulic cylinder and the support.

[0009] Furthermore, the first side plate has a first slot at the fixed end for mounting the hydraulic cylinder, a first fixing plate is provided in the first slot, the first fixing plate is detachably embedded in the first slot, and the first fixing plate has a first mounting hole for mounting the connecting shaft.

[0010] The second side plate has a second slot at the fixed end for mounting the hydraulic cylinder, and a second fixing plate is provided in the second slot. The second fixing plate is detachably embedded in the second slot, and the second fixing plate has a second mounting hole for mounting the connecting shaft.

[0011] Since both the first fixing plate and the second fixing plate are detachably connected to the first and second slots respectively, it is convenient to disassemble, replace, and maintain the hydraulic cylinder when it malfunctions or requires maintenance.

[0012] Furthermore, a first trunnion bushing is installed in the first mounting hole, and a second trunnion bushing is installed in the second mounting hole. One end of the connecting shaft is connected to the first trunnion bushing, and the other end is connected to the second trunnion bushing. The stability of the hydraulic cylinder on the support is further improved by the first and second trunnion bushings.

[0013] Furthermore, the first side plate is bolted to the first fixed plate via two symmetrical bolt holes, and the second side plate is bolted to the second fixed plate via two symmetrical bolt holes; this facilitates the disassembly of the first and second fixed plates.

[0014] Furthermore, the base plate of the support is provided with bolt holes for bolt connection with the roller conveyor; this facilitates the disassembly of the support from the roller conveyor.

[0015] Furthermore, the first side plate and the bottom plate, and the second side plate and the bottom plate are respectively connected by welding, and the welding effect is enhanced by welding ear plates between the first side plate and the bottom plate, and the second side plate and the bottom plate; or, the first side plate, the second side plate and the bottom plate are integrated into a single structure.

[0016] Furthermore, a first cover plate with pre-drilled holes is bolted to the first side plate, and a second cover plate with pre-drilled holes is bolted to the second side plate; or, the first side plate and the first cover plate are welded together, and the second side plate and the second cover plate are welded together; or, the first side plate and the first cover plate are integrally formed, and the second side plate and the second cover plate are integrally formed.

[0017] Furthermore, two sliding plates are provided in the groove of the support for the pusher to slide.

[0018] Furthermore, the slide plate is bolted to the base plate through pre-drilled holes; or, the slide plate and the base plate are connected by welding.

[0019] Analysis shows that this utility model provides a steel pushing device for improving sawing efficiency, including a support, a pusher head, a receiving platform, and a hydraulic cylinder. The support consists of a base plate, a first side plate, and a second side plate. The fixed end of the hydraulic cylinder is installed on the support. A groove formed by the base plate, the first side plate, and the second side plate is used to accommodate the hydraulic cylinder. One end of the pusher head extends into the groove and connects to the telescopic end of the hydraulic cylinder. This ensures that the pusher head can move linearly back and forth in the groove and achieves automated control. The receiving platform is slidably disposed on the side of the first and second side plates away from the base plate along the extension direction of the groove, covering at least a portion of the top opening of the groove. The surface of the receiving platform away from the base plate forms a bearing surface. The pusher head is fixed to the receiving platform, and one end protrudes from the bearing surface, thereby ensuring that the receiving platform moves with the pusher head during the pushing process, preventing iron scale and sawdust from falling into the groove during steel pipe sawing and increasing service life.

[0020] Compared with the closest existing technology, the technical solution provided by this utility model has the following advantages:

[0021] 1. In response to the current problem that steel materials need to be manually moved and sawed on-site to ensure production rhythm, which has a high risk factor, high labor intensity and long time consumption, this utility model has a simple structure, high transmission efficiency, can realize automated control, and is easy to operate.

[0022] 2. For steel pieces with only one or a few pieces, the sawing action is long and the waiting time is long. The frequency of use of multiple cuts and single cuts is the same, resulting in energy waste and low production efficiency. This utility model places the steel on a receiving platform and uses a hydraulic cylinder to provide power for pushing the steel, thereby improving the overload protection capability of the device. The hydraulic cylinder can also achieve stepless speed regulation according to the needs.

[0023] 3. In view of the technical problem that existing traditional equipment is not suitable for use in harsh environments, this utility model optimizes the sealing design by using a receiving platform to prevent sawdust and other materials from falling into the device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Therefore, they should not be construed as limitations on this utility model.

[0041] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale.

[0042] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0043] like Figure 1 and Figure 2As shown, this utility model provides a technical solution: a steel pushing device for improving sawing efficiency, including a support 1, a pusher 2, a receiving platform 3, and a hydraulic cylinder. The support 1 is composed of a base plate 4, a first side plate 5, and a second side plate 6. The first side plate 5 and the second side plate 6 are arranged along a first direction and are respectively fixedly connected to the base plate 4. The base plate 4, the first side plate 5, and the second side plate 6 form a groove for accommodating the hydraulic cylinder. The fixed end of the hydraulic cylinder is installed on the support 1.

[0044] As can be seen from the above analysis, the groove formed by the base plate 4, the first side plate 5, and the second side plate 6 is used to ensure that the pusher 2 can move linearly back and forth in the groove, thereby ensuring that the steel pipe pushed by the pusher 2 can move linearly; and the groove is used to accommodate the oil cylinder, making the device structure more compact and greatly reducing the volume of the steel pushing device.

[0045] The receiving platform 3 is slidably disposed on the side of the first side plate 5 and the second side plate 6 away from the bottom plate 4 along the extension direction of the groove, for covering at least a portion of the top opening of the groove, and the surface of the receiving platform 3 away from the bottom plate 4 forms a bearing surface; the push head 2 is fixed to the receiving platform 3, with one end protruding from the bearing surface and the other end extending into the groove and connected to the telescopic end of the oil cylinder.

[0046] As can be seen from the above analysis, the receiving platform 3 can be slidably disposed on the side of the first side plate 5 and the second side plate 6 away from the bottom plate 4 along the extension direction of the groove, so as to cover at least a part of the top opening of the groove, thereby ensuring that the iron scale and sawdust generated during the sawing process of the steel pipe fall into the groove, thereby affecting the sliding of the pusher 2 in the groove.

[0047] like Figure 12 As shown, the surface of the receiving platform 3 away from the base plate 4 forms a bearing surface, providing a plane capable of bearing the steel pipe to be pushed, thereby improving the overload capacity of the device.

[0048] The pusher 2 is fixed to the receiving platform 3, with one end protruding from the bearing surface and the other end extending into the groove and connected to the telescopic end of the hydraulic cylinder. This ensures that when the hydraulic cylinder drives the pusher 2 to move, the bearing platform 3 can move synchronously with the pusher 2, thereby driving the steel pipe on the bearing surface to move. Furthermore, during the process of the steel pipe being pushed, since the receiving platform 3 moves synchronously with the steel pipe, the iron scale and sawdust generated after sawing the steel pipe are blocked by the receiving platform 3, improving the sealing effect during the operation of the device.

[0049] Preferably, such as Figure 3As shown, the fixed end of the hydraulic cylinder is mounted on the first side plate 5 and the second side plate 6 via a connecting shaft. The extension direction of the connecting shaft is parallel to the arrangement direction of the first side plate 5 and the second side plate 6. The purpose is to ensure that when the hydraulic cylinder malfunctions and needs to be replaced or maintained, the hydraulic cylinder can be disassembled by removing the connecting shaft, which facilitates replacement and maintenance.

[0050] More preferably, such as Figure 1 and Figure 2 As shown, the first side plate 5 has a first slot 15 at the fixed end for mounting the oil cylinder. The first slot 15 has a first fixing plate 10, which is detachably embedded in the first slot 15. The first fixing plate 10 has a first mounting hole 17 for mounting the connecting shaft.

[0051] The second side plate 6 has a second slot 16 at the fixed end for mounting the oil cylinder. The second slot 16 has a second fixing plate 13, which is detachably embedded in the second slot 16. The second fixing plate 13 has a second mounting hole 18 for mounting the connecting shaft.

[0052] As can be seen from the above analysis, when the hydraulic cylinder needs to be disassembled for maintenance and replacement, since the two ends of the connecting shaft are installed at the first mounting hole 17 and the second mounting hole 18, and the first fixing plate 10 and the first slot 15 on the first side plate 5 are detachable, the connecting shaft can be disassembled at one end simply by loosening the first fixing plate 10. Similarly, the connecting shaft can be disassembled at the other end by loosening the second fixing plate 13.

[0053] More preferably, such as Figure 1 and Figure 2 As shown, a first trunnion bushing 9 is installed in the first mounting hole 17, and a second trunnion bushing 14 is installed in the second mounting hole 18. One end of the connecting shaft is connected to the first trunnion bushing 9, and the other end is connected to the second trunnion bushing 14.

[0054] As can be seen from the above analysis, inserting both ends of the connecting shaft into the first trunnion seat copper sleeve 9 and the second trunnion seat copper sleeve 14 respectively further improves the convenience of cylinder disassembly and the stability of cylinder installation.

[0055] Preferably, such as Figure 2 As shown, the first side plate 5 is bolted to two symmetrical bolt holes reserved on the first fixing plate 10, and the second side plate 6 is bolted to two symmetrical bolt holes reserved on the second fixing plate 13.

[0056] As can be seen from the above analysis, the first fixing plate 10 installed on the first side plate 5 and the second fixing plate 13 installed on the second side plate 6 further provide good support for the hydraulic cylinder and improve the overload protection capability of the device; the first side plate 5 and the first fixing plate 10 are bolted together, and when the first fixing plate 10 needs to be replaced, it can be removed simply by loosening the bolts fixed to the first fixing plate 10. Similarly, the second fixing plate 13 can be removed from the second side plate, which is convenient for disassembly.

[0057] Preferably, such as Figure 4 As shown, the base plate 4 of the support 1 is provided with bolt holes for bolt connection with the roller conveyor; the purpose is to facilitate the installation of the steel pushing device under the conveyor roller conveyor of the abrasive wheel saw and the length-keeping machine by bolts when the steel pushing device is working, and to loosen the bolts and stop on the side of the roller conveyor after the work is completed.

[0058] Preferably, the first side plate 5 and the bottom plate 4, and the second side plate 6 and the bottom plate 4 are respectively connected by welding, and the welding effect is enhanced by welding ear plates 11 between the first side plate 5 and the bottom plate 4, and the second side plate 6 and the bottom plate 4; or, the first side plate 5, the second side plate 6 and the bottom plate 4 are integrated into a single structure.

[0059] As can be seen from the above analysis, the first side plate 5 and the bottom plate 4, and the first side plate 5 and the bottom plate 4 are respectively connected by welding. The welding effect is enhanced by welding ear plates 11 between the first side plate 5 and the bottom plate 4, and between the second side plate 6 and the bottom plate 4. The structure is simple, easy to manufacture, and has higher strength. The first side plate 5, the second side plate 6 and the bottom plate 4 adopt an integrated structure, which makes the support 1 more integral and more stable.

[0060] Preferably, such as Figure 2 and Figure 10 As shown, a first cover plate 7 with pre-drilled holes is bolted to the first side plate 5, as... Figure 11 As shown, the second side plate 6 is bolted to the second cover plate 8 with reserved holes; or, the first side plate 5 and the first cover plate 7 are welded together, and the second side plate 6 and the second cover plate 7 are welded together; or, the first side plate 5 and the first cover plate 7 are integrally formed, and the second side plate 6 and the second cover plate 8 are integrally formed.

[0061] As can be seen from the above analysis, by pre-drilling holes on the first side plate 5 and the second side plate 6 and bolting them to the first cover plate 7 and the second cover plate 8, it is convenient to replace the first side plate 5 and the second side plate 6. It is only necessary to loosen the bolts fixed on the first side plate 5 and the second side plate 6, which is easy to disassemble; or, the first side plate 5 and the second side plate 6 are welded to the first cover plate 7 and the second cover plate 8 respectively, which is simple to manufacture and has higher strength; or, the first side plate 5 and the first cover plate 7 adopt an integral structure, and the second side plate 6 and the second cover plate 8 adopt an integral structure, which has better integrity and further improves the stability of the receiving platform 3.

[0062] Preferably, such as Figure 2 As shown, two sliding plates 12 are provided in the groove of the support 1 for the push head 2 to slide. The purpose is to reduce the friction between the push head 2 and the base plate 4 of the support 1 when the push head slides in the groove, thereby improving the service life of the push head 2 and the support 1, and improving the smoothness of the push head 2 sliding in the groove, thus improving the working efficiency of the device.

[0063] More preferably, such as Figure 6 As shown, the slide plate 12 is bolted to the base plate 4 through pre-drilled holes; or, the slide plate 12 and the base plate 4 are welded together.

[0064] As can be seen from the above analysis, the slide plate 12 is bolted to the base plate 4 through the reserved holes. When the device has been running for a period of time, if the slide plate 12 is damaged and needs to be replaced, it is only necessary to loosen the bolts fixing the slide plate 12; or, the slide plate 12 and the base plate 4 are connected by welding to improve the integrity of the slide plate 12 and the base plate 4 and prevent the push head 2 from causing the slide plate 12 to loosen on the base plate 4 when sliding.

[0065] The working process of using this device to push the steel pipe is as follows:

[0066] First, the steel pushing device is bolted to the bottom of the abrasive wheel saw and the length-cutting machine conveyor rollers through the reserved holes in the base plate 4 of the support 1, with the push head 2 higher than the rollers. The steel pipe is placed on the receiving platform 3, with one end in contact with the push head 2. The hydraulic cylinder is activated, and the telescopic shaft of the hydraulic cylinder drives the push head to slide on the slide plate 12 in the groove formed by the base plate 4, the first side plate 5, and the second side plate 6 of the support 1. The push head 2 then drives the receiving platform 3 to slide synchronously on the first cover plate 7 and the second cover plate 8. Thus, the push head 2 and the receiving platform 3 together drive the steel pipe to move synchronously, transporting the steel pipe to the sawing position. At the same time, the receiving platform 3 prevents iron scale and sawdust generated during steel pipe sawing from falling into the groove, avoiding damage to the device and improving the service life of the device.

[0067] In summary, the steel pushing device of this utility model achieves the following technical effects:

[0068] 1) In the existing technology, when there are only one or a few steel pieces, the sawing action is long and the waiting time is long. The frequency of use of multiple lengths and single lengths is the same, which leads to energy waste and low production efficiency. On-site manual relocation of steel pieces and sawing are required to ensure production rhythm. The risk factor is high and the labor intensity of workers is high and time-consuming. A steel pushing device that can achieve automated control and safe operation is provided.

[0069] 2) The groove formed by the base plate 4, the first side plate 5 and the second side plate 6 is used to ensure that the pusher 2 can move linearly back and forth in the groove, and the groove is used to accommodate the oil cylinder, making the device structure more compact and greatly reducing the volume of the steel pushing device.

[0070] 3) The receiving platform 3 can be slidably disposed on the side of the first side plate 5 and the second side plate 6 away from the bottom plate 4 along the extension direction of the groove, and covers at least a portion of the top opening of the groove, thereby ensuring that iron scale and sawdust generated during the sawing process of the steel pipe fall into the groove and improve the service life of the device.

[0071] 4) The first slot 15 of the first fixing plate 10 and the first side plate 5 are detachable. Therefore, the connecting shaft can be disassembled at one end by simply loosening the bolts on the first fixing plate 10. Similarly, the connecting shaft can be disassembled at the other end by loosening the bolts on the second fixing plate 13. This ensures that when the hydraulic cylinder malfunctions and needs to be replaced or maintained, the hydraulic cylinder can be disassembled by removing the connecting shaft, which is convenient for replacement and maintenance.

[0072] 5) Two sliding plates 12 are provided in the groove of the support 1 for the push head to slide, which reduces the friction between the push head 2 and the base plate 4 of the support 1 when the push head 2 slides in the groove, thereby improving the service life of the push head 2 and the support 1.

[0073] 6) The base plate 4 of the support 1 is provided with bolt holes for bolt connection with the roller conveyor, which makes it easy for the steel pushing device to be installed under the conveyor roller conveyor of the abrasive wheel saw and the length-keeping machine by bolts. After the work is completed, the bolts are loosened and the device stops on the side of the roller conveyor, which improves the flexibility of the device.

[0074] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
