Description

Technical Field

[0001] The utility model relates to the field of electric furnace accessories, and particularly relates to an inlet and outlet platform for an electric furnace. Background Art

[0002] When putting a workpiece or product into an electric furnace or taking it out of the electric furnace, an inlet and outlet platform for auxiliary material placement and transfer is generally required. However, as a processing device, the electric furnace has different states for the workpiece before and after it enters and exits the furnace. The workpiece just taken out of the electric furnace often remains at a high temperature.

[0003] Therefore, the same inlet and outlet platform may not be suitable for workpieces in two states, and setting two inlet and outlet platforms will greatly increase the cost.

[0004] Moreover, when putting the workpiece into the inlet and outlet platform, it is preferably slightly higher or the same as the lower edge of the inlet and outlet of the electric furnace, and when taking out the workpiece, it is preferably slightly lower or the same as the lower edge of the inlet and outlet of the electric furnace. Only in this way can the workpiece enter and exit without obstruction. To make the height of the inlet and outlet platform exactly the same as the lower edge of the inlet and outlet of the electric furnace, especially to still maintain the same after long-term use, high requirements are imposed on the materials, production processes, etc. of the inlet and outlet platform. Content of the Utility Model

[0025] Specific embodiments and principles

[0026] To make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below in conjunction with specific embodiments.

[0027] It should be noted that unless otherwise defined, the technical terms or scientific terms used in the present utility model should have the ordinary meanings understood by those with ordinary skills in the field to which the present utility model belongs. The "first", "second" and similar terms used in the present utility model do not indicate any order, quantity or importance, but are only used to distinguish different components. The terms such as "including" or "comprising" mean that the elements or objects appearing before this term cover the elements or objects listed after this term and their equivalents, without excluding other elements or objects. The terms such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. The "upper", "lower", "left", "right", etc. are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0028] In the first aspect of the present utility model, as Figure 1 and Figure 2 shown, the present utility model mainly includes two parts, namely the electric furnace 101 part and the access platform part. Among them, a pair of positioning plug boards 103 are added to the electric furnace 101 part on the basis of existing mature electric furnace products. The positioning plug boards 103 are located directly below the electric furnace door 102 installed at the inlet and outlet of the electric furnace 101. The electric furnace door 102 is rotatably connected to the electric furnace 101. Since the inlet and outlet of the electric furnace 101 used in the present utility model are located directly in front of the electric furnace 101, the positioning plug boards 103 are also located directly in front of the electric furnace 101.

[0029] Correspondingly, as Figure 2 andFigure 3 As shown, a corresponding positioning jack 113 is also provided inside the main body 104 of the access platform. The two cooperate to position the entire access platform. A magnet 114 that can adsorb to the positioning plug 103 is also provided inside the positioning jack 113, which is used for simple fixation and positioning of the access platform.

[0030] In addition, universal wheels 111 are provided below the main body 104, and a handle 112 is rotatably connected to the outside of the main body 104. The two cooperate to transfer the access platform and the workpiece.

[0031] The key point is that, as Figure 3 、 Figure 4 and Figure 5 shown, a plurality of bosses 105 are provided on the main body 104 of the access platform. These bosses 105 are in the shape of long strips, and the front and rear lengths are the same as the front and rear lengths of the main body 104 of the access platform. A plurality of rollers 106 are provided on each boss 105. The number and positions of the rollers 106 on each boss 105 are the same. These rollers 106 are rotatably connected to the boss 105, and the rolling direction of the rollers 106 is also the front and rear direction.

[0032] These rollers 106 serve as the access platform during discharging. Since the temperature of the workpiece or semi-finished product just discharged from the electric furnace 101 is relatively high, common plastic and metal materials are not suitable. Plastic materials will melt when exposed to high temperatures, and metal materials will also rust more easily when encountering high-temperature materials, which will easily cause rust to adhere to the workpiece or semi-finished product. Therefore, the rollers 106 are made of high-temperature-resistant ceramic materials or other high-temperature-resistant and stable materials. Since the bosses 105 are in the shape of long strips, a square groove 107 is provided between adjacent bosses 105. More precisely, square grooves 107 are also provided on both sides of the boss 105.

[0033] In addition, as Figure 4 and Figure 5, there are also several left - right horizontal arc - shaped grooves on the convex platform 105. Rollers 108 are arranged in the arc - shaped grooves. These rollers 108 are movably connected to the arc - shaped grooves, and the rollers 108 can rise from the arc - shaped grooves. The rollers 108 are rotatably connected to the movable plate 109 and the support plate 110, and the movable plate 109 and the support plate 110 are movably connected in the square groove 107. Among them, the movable plate 109 is located in the square groove 107 on the outermost side (the leftmost or the rightmost), and the support plate 110 is located in the square groove 107 on the other side relative to (the movable plate 109), not necessarily on the outermost side. One end of the roller 108 is directly rotatably connected to the movable plate 109, and no other relative movement can occur except rotation. The roller 108 is movably connected to the support plate 110. The support plate 110 is also provided with arc - shaped grooves similar to those on the convex platform 105, and the roller 108 is rotatably connected therein. The support plate 110 mainly plays a role in supporting and balancing the roller 108.

[0034] Two sets of inlet - outlet components, namely the roller 106 and the roller 108. The roller 106 is used for workpiece discharging, while the roller 108 is used for workpiece feeding. The two sets of inlet - outlet components are made of different materials. The roller 106 is made of high - temperature - resistant ceramic material, and the roller 108 is made of plastic or metal material. Therefore, the roller 106 is suitable for workpieces or products in two high - temperature states, while the roller 108 is suitable for workpieces or products in low - temperature states.

[0035] Preferably, telescopic rods 118 are also fixedly connected to the bottoms of the movable plate 109 and the support plate 110. The telescopic rods 118 are movably connected to the main body 104 and are used to drive the lifting of the roller 108. There is also a cavity in the main body 104. A plurality of hydraulic cylinders 116 are fixedly connected in this cavity. The output shaft of each hydraulic cylinder 116 is connected to a telescopic rod 118. The telescopic rod 118 passes through and is slidably connected to the top plate of the main body 104. A hydraulic pump 115 is also provided at the center of the cavity. The hydraulic pump 115 is connected to the hydraulic cylinders 116 through a connecting pipe 117.

[0036] Two telescopic rods 118 are provided at the bottom of each of the movable plate 109 and the support plate 110. Therefore, there are four groups of hydraulic cylinders 116, which are respectively located directly below the respective telescopic rods 118. The hydraulic pump 115 and the hydraulic cylinders 116 are both fixedly connected in the main body 104.

[0037] Therefore, the roller 108 has two states: rising and falling. The height of the upper end point of the rising roller 108 is higher than the lower edge of the inlet and outlet of the electric furnace. The height of the upper end point of the falling roller 108 is lower than the upper end point of the roller 106, and the height of the upper end point of the roller 106 is lower than the lower edge of the inlet and outlet of the electric furnace. This facilitates the entry and exit of workpieces or products and avoids bumping.

[0038] Specifically, when the roller 108 needs to be lifted, the hydraulic pump 115 supplies hydraulic pressure to the hydraulic cylinder 116 through the connecting pipe 117. The output shaft of the hydraulic cylinder 116 drives the telescopic rod 118 to move upward, thereby causing the movable plate 109 and the support plate 110 to move upward and drive the roller 108 to lift. Similarly, when the roller 108 needs to descend, the hydraulic pump 115 stops supplying hydraulic pressure, and the roller 108, the movable plate 109, and the support plate 110 naturally fall under their own gravity. Detailed implementation mode

[0039] When using the present utility model to enter and exit the platform, if it is for feeding, the hydraulic pump 115 is started in advance. The hydraulic pump 115 supplies hydraulic pressure to the hydraulic cylinder 116 through the connecting pipe 117. The output shaft of the hydraulic cylinder 116 drives the telescopic rod 118 to move upward, thereby causing the movable plate 109 and the support plate 110 to move upward and drive the roller 108 to lift. Then, the workpiece to be processed is placed on the roller 108.

[0040] Then, through the universal wheels 111 under the main body 104 and the handle 112 rotatably connected to the outside of the main body 104, the entering and exiting platform is moved to the front of the electric furnace 101. Then, the positioning plug 103 is inserted into the positioning socket 113, and the magnet 114 in the positioning socket 113 will attract the positioning plug to achieve simple fixation and positioning of the entering and exiting platform. Then, the furnace door 102 at the inlet and outlet of the electric furnace 101 is opened, and the workpiece is pushed to enter the electric furnace 101. During this process, the roller 108 will rotate accordingly, facilitating the movement of the workpiece. Moreover, the upper endpoint height of the roller 108 in the lifted state is higher than the lower edge of the inlet and outlet of the electric furnace, so the workpiece can easily enter the electric furnace 101, and then the furnace door 102 is closed.

[0041] When discharging, the hydraulic pump 115 is turned off, and the hydraulic pump 115 stops supplying hydraulic pressure. The roller 108, the movable plate 109, and the support plate 110 naturally fall under their own gravity. At this time, the upper endpoint height of the roller 108 in the fallen state is lower than the upper endpoint height of the roller 106. Therefore, the roller 106 serves as the entering and exiting platform during discharging. Then, the furnace door 102 is opened, and the high-temperature workpiece is taken out and placed on the roller 106. During this process, the roller 106 rotates accordingly, facilitating the movement of the workpiece. Moreover, the upper endpoint height of the roller 106 is lower than the lower edge of the inlet and outlet of the electric furnace, so the workpiece can easily move onto the roller 106.

[0042] Finally, the positioning plug 103 is pulled out, and the entering and exiting platform is moved to the designated position through the universal wheels 111 and the handle 112.

[0043] Based on the above, the utility model adopts two sets of inlet and outlet components, namely the roller 106 and the roll 108, and the two sets of inlet and outlet components are made of different materials to adapt to workpieces or products in two states of low temperature and high temperature. The use of the roller 106 and the roll 108 as the two sets of inlet and outlet components is switched by lifting the roll 108, which is simple and convenient. The roll 108 for carrying the workpiece before processing is lifted slightly higher than the lower edge of the inlet and outlet of the electric furnace, and the roller 106 for carrying the workpiece after processing is slightly lower than the lower edge of the inlet and outlet of the electric furnace, which facilitates the entry and exit of the workpiece and avoids bumping. The positioning jack 113 with a magnet is provided to cooperate with the positioning plug 103, which can simply fix the inlet and outlet platform and ensure the stability of the workpiece during entry and exit.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the utility model shall be included within the protection scope of the utility model.
