Description

Technical Field

[0001] This utility model relates to the field of cleaning and maintenance technology of tension leveling machines, and in particular to a slag blowing and slag removal device for tension leveling machines. Background Technology

[0002] During normal production at the No. 1 Steelmaking Plant, as the casting time gradually increases, a significant amount of iron oxide accumulates inside the straightening machine. This accumulated iron oxide may scratch the surface of the steel billet, resulting in scratches on the billet surface and affecting production quality.

[0003] Traditionally, cleaning the iron oxide inside a straightening machine is done manually. Workers use compressed air to blow away the iron oxide from the machine using a blowing device. This manual blowing method is not only time-consuming and labor-intensive, but also inefficient and poses certain safety hazards to workers. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a slag blowing and slag removal device for a straightening machine, so as to solve the technical problems of low efficiency and safety hazards in the existing technology of manually approaching the straightening machine for blowing and cleaning.

[0005] To achieve the above objectives, this utility model provides a slag blowing and slag removal device for a straightening machine, including a slag blowing pipe that can extend into the interior of the straightening machine, and the slag blowing and slag removal device further includes: The mounting base has a main connecting pipe fixedly connected to it, and a fixed pipe is fixedly connected to the front end of the main connecting pipe. The slag blowing pipe is movably connected to the fixed pipe. The mounting base is also connected to a gas supply hose, which communicates with the inner cavity of the slag blowing pipe. A rotating inner tube is rotatably connected inside the slag blowing pipe. Several jet pipes are fixedly connected to the slag blowing pipe. The rotating inner tube separates the jet pipes from the inner cavity of the slag blowing pipe. Multiple opening slots are provided on the rotating inner tube. The opening slots can be connected to the jet pipes after they coincide with the opening positions of the inner ends of the jet pipes. A fixed ring is sleeved on the fixed pipe and fixedly connected to the lower end of the slag blowing pipe. A position switching mechanism is provided between the fixed ring and the rotating inner pipe to control the rotating inner pipe to rotate back and forth within a certain range.

[0006] Furthermore, the mounting base is also connected to a cable, the outer wall of the fixing tube is provided with a conductive strip, and the inner wall of the fixing ring is provided with a connecting conductive sheet that contacts and slides in connection with the conductive strip.

[0007] Furthermore, the position switching mechanism includes movable teeth fixedly connected to the lower end of the rotating inner tube. The fixed ring is provided with a section of circular tube with the same thickness as the rotating inner tube. The upper end of the circular tube is provided with fixed teeth. The movable teeth and fixed teeth are provided in multiples and their positions are staggered with gaps.

[0008] Furthermore, each of the two side walls of the fixed tooth is provided with an electromagnet, the movable tooth is made of a metal material that can be magnetically attracted, and the electromagnet is connected to the connecting conductive sheet.

[0009] Furthermore, the movable tooth has several telescopic blocks and telescopic grooves on its two side walls. The telescopic blocks are slidably connected in the telescopic grooves, and springs are also provided in the telescopic grooves. The two ends of the springs are respectively connected to the inner end of the telescopic blocks and the bottom of the telescopic grooves.

[0010] Furthermore, the gas delivery hose is connected to the jet pipe via a connecting main pipe, a fixed pipe, and an opening groove on the rotating inner pipe.

[0011] Furthermore, a driven ring is rotatably connected to the main connecting pipe, and multiple connecting rods are fixedly connected to the driven ring. The fixed ring is provided with a sliding hole, and the connecting rods pass through the sliding hole and are slidably connected to it.

[0012] Furthermore, the fixing ring is also equipped with an electromagnetic lock that cooperates with the connecting rod. The electromagnetic lock is connected to the connecting conductive plate and attracts the connecting rod after being energized to increase the friction force for positioning.

[0013] Furthermore, the connecting rods are provided in four parts, arranged at equal angles, and the outer ends of all the connecting rods are slidably connected to the slag blowing pipe.

[0014] Furthermore, a drive belt is connected to the driven coil, and the other end of the drive belt is connected to the driving pulley, which is fixedly connected to the output shaft of the rotating motor.

[0015] The beneficial effects of this utility model are as follows: 1. The slag-blowing pipe, which can extend and retract, can be inserted into a specific position inside the leveling machine when cleaning is required. This allows the air jet pipe to target specific locations for cleaning, removing excess iron oxide through compressed gas. Compared to manual cleaning, this method is not only more efficient but also eliminates safety hazards for workers.

[0016] 2. A rotating inner tube is installed inside the slag blowing pipe. By rotating the inner tube, the position of the slag blowing pipe can be switched between a closed and an open state. In the closed state, gas cannot escape. Air can be introduced or extracted through the air supply hose to drive the extension and retraction of the slag blowing pipe, realizing the function of automatically controlling the forward and backward extension and retraction of the slag blowing pipe. In the open state, compressed gas can be ejected through the jet pipe for purging operation.

[0017] 3. A position switching mechanism is installed between the fixed ring and the rotating inner tube, which can switch the position of the rotating inner tube, thereby switching the slag blowing pipe to a closed or ventilated state. When the electromagnet on one side of the fixed tooth is de-energized, the electromagnet on the other side is energized. The telescopic block, under the action of the spring, causes the movable tooth (rotating inner tube) to spring open and rotate, and finally be attracted by the electromagnet on the other side, completing the switching. The structure is simple and the response is sensitive.

[0018] 4. The rotating motor is set up to drive the entire slag blowing pipe and air jet pipe to rotate through the transmission mechanism (driven coil, connecting rod, fixed ring), so as to realize the rotation and cleaning of the slag blowing pipe and air jet pipe, ensuring that the cleaning reaches all positions in the straightening machine and improving the cleaning effect.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0031] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0032] The first aspect of this utility model is as follows: Figures 1-9 As shown, traditionally, cleaning the iron oxide inside a straightening machine relies on manual labor. Workers use compressed air to blow away the iron oxide from the machine using a blowing device. This manual method is not only time-consuming and labor-intensive, but also inefficient and poses safety hazards to workers. Therefore, this invention designs an automatic cleaning device that uses automated mechanical operation to clean the iron oxide inside the straightening machine, eliminating the need for manual operation.

[0033] Specifically, a slag-blowing pipe 104 that can extend into the interior of the leveling machine is designed, and several air jet pipes 105 are fixedly connected to the slag-blowing pipe 104. A mounting base 101 is designed to ensure the stability of the entire equipment, and a connecting main pipe 102 is fixedly connected to the mounting base 101. A fixing pipe 103 is fixedly connected to the front end of the connecting main pipe 102. The slag-blowing pipe 104 is movably connected to the fixing pipe 103. A gas delivery hose 117 is also connected to the mounting base 101, and the gas delivery hose 117 communicates with the inner cavity of the slag-blowing pipe 104.

[0034] A slag-blowing pipe 104, capable of retracting and extending back and forth, can be extended, particularly the air jet pipe 105 on the slag-blowing pipe 104, into a specific location inside the leveling machine when cleaning is required. This allows the air jet pipe 105 to target specific areas, removing excess iron oxide through compressed gas. Compared to manual blowing, this method is not only more efficient but also eliminates safety hazards for workers.

[0035] Inside the slag blowing pipe 104, a rotating inner pipe 106 is rotatably connected. Several jet pipes 105 are fixedly connected to the slag blowing pipe 104. The rotating inner pipe 106 separates the jet pipes 105 from the inner cavity of the slag blowing pipe 104. Multiple opening slots 107 are opened on the rotating inner pipe 106. When the opening slots 107 coincide with the opening positions of the inner ends of the jet pipes 105, they can conduct gas through the jet pipes 105. Therefore, the gas delivery hose 117 is finally connected to the jet pipes 105 through the connecting main pipe 102, the fixed pipe 103, and the opening slots 107 on the rotating inner pipe 106.

[0036] Additionally, a fixing ring 109 is provided, which is sleeved on the fixing pipe 103 and fixedly connected to the lower end of the slag blowing pipe 104. A position switching mechanism is provided between the fixing ring 109 and the rotating inner pipe 106 to control the rotating inner pipe 106 to rotate back and forth within a certain range.

[0037] A rotating inner tube 106 is installed inside the slag blowing pipe 104. By rotating the inner tube 106, the position of the slag blowing pipe 104 can be switched between a closed and an open state. In the closed state, gas cannot escape. Air can be introduced or extracted through the air supply hose 117 to drive the extension and retraction of the slag blowing pipe 104, realizing the function of automatically controlling the forward and backward extension and retraction of the slag blowing pipe 104. In the open state, compressed gas can be ejected through the jet pipe 105 to perform purging operations.

[0038] The second aspect of this utility model is as follows: Figures 1-9 As shown, in order to achieve automated mechanical operation during construction, a cable 118 is connected to the mounting base 101, a conductive strip 119 is provided on the outer wall of the fixing pipe 103, and a connecting conductive piece 120 is provided on the inner wall of the fixing ring 109, which contacts and slides in connection with the conductive strip 119.

[0039] The position switching mechanism includes movable teeth 108 fixedly connected to the lower end of the rotating inner tube 106. A circular tube with the same thickness as the rotating inner tube 106 is provided on the fixed ring 109, and fixed teeth 110 are provided at the upper end of the circular tube. Multiple movable teeth 108 and fixed teeth 110 are provided, and their positions are staggered with gaps. An electromagnet 125 is provided on each of the two side walls of the fixed teeth 110. The movable teeth 108 are made of a metal material that can be magnetically attracted. The electromagnets 125 are connected to the connecting conductive sheet 120.

[0040] In addition, several telescopic blocks 122 and telescopic grooves 123 are provided on the two side walls of the movable tooth 108. The telescopic blocks 122 are slidably connected in the telescopic grooves 123, and springs 124 are also provided in the telescopic grooves 123. The two ends of the springs 124 are respectively connected to the inner end of the telescopic blocks 122 and the bottom of the telescopic grooves 123.

[0041] A position switching mechanism is provided between the fixed ring 109 and the rotating inner tube 106, which can switch the position of the rotating inner tube 106, thereby switching the slag blowing pipe 104 to a closed or ventilated state. When the electromagnet 125 on one side of the fixed tooth 110 is de-energized, the electromagnet 125 on the other side is energized. The telescopic block 122, under the action of the spring 124, causes the movable tooth 108 (rotating inner tube 106) to spring open and rotate, and finally be attracted by the electromagnet 125 on the other side, completing the switching. The structure is simple and the response is sensitive.

[0042] To better ensure the cleaning effect, a driven ring 113 is rotatably connected to the connecting main pipe 102. Multiple connecting rods 112 are fixedly connected to the driven ring 113. A sliding hole 111 is provided on the fixing ring 109, through which the connecting rods 112 pass and slide. An electromagnetic lock 121, which cooperates with the connecting rods 112, is also provided inside the fixing ring 109. The electromagnetic lock 121 is connected to the connecting conductive plate 120 and, when energized, attracts the connecting rods 112 to increase friction and position them. A drive belt 116 is connected to the driven ring 113, and the other end of the drive belt 116 is connected to the drive wheel 115, which is fixedly connected to the output shaft of the rotating motor 114.

[0043] The rotating motor 114 is configured to drive the entire slag blowing pipe 104 and the jet pipe 105 to rotate through the transmission mechanism (driven coil 113, connecting rod 112, and fixing ring 109), thereby realizing the rotational cleaning of the slag blowing pipe 104 and the jet pipe 105, ensuring that the cleaning reaches all positions in the straightening machine and improving the cleaning effect.

[0044] Preferably, there are four connecting rods 112 arranged at equal angles, and the outer ends of all connecting rods 112 are slidably connected to the slag blowing pipe 104.

[0045] In summary, this utility model features a slag-blowing pipe 104 that can extend and retract, allowing the slag-blowing pipe 104, especially the air jet pipe 105 on it, to be inserted into a specific location inside the leveling machine when cleaning is required. This enables the air jet pipe 105 to target specific areas for cleaning, removing excess iron oxide through compressed gas. Compared to manual cleaning, this method is not only more efficient but also eliminates safety hazards for workers.

[0046] A rotating inner tube 106 is installed inside the slag blowing pipe 104. By rotating the inner tube 106, the position of the slag blowing pipe 104 can be switched between a closed and an open state. In the closed state, gas cannot escape. Air can be introduced or extracted through the air supply hose 117 to drive the extension and retraction of the slag blowing pipe 104, realizing the function of automatically controlling the forward and backward extension and retraction of the slag blowing pipe 104. In the open state, compressed gas can be ejected through the jet pipe 105 for purging. A position switching mechanism is set between the fixed ring 109 and the rotating inner tube 106, which can switch the position of the rotating inner tube 106 to switch the slag blowing pipe 104 between the closed and open states. When the electromagnet 125 on one side of the fixed tooth 110 is de-energized, the electromagnet 125 on the other side is energized. The telescopic block 122, under the action of the spring 124, causes the movable tooth 108 (rotating inner tube 106) to spring open and rotate, and finally be attracted by the electromagnet 125 on the other side, completing the switching. The structure is simple and the response is sensitive.

[0047] In addition, a rotating motor 114 is provided to drive the entire slag blowing pipe 104 and jet pipe 105 to rotate through a transmission mechanism (driven coil 113, connecting rod 112, and fixing ring 109), so as to realize the rotational cleaning of the slag blowing pipe 104 and jet pipe 105, ensuring that the cleaning reaches all positions in the straightening machine and improving the cleaning effect.
