Description

[0002] In the related art, there are many problems in the installation method of the encoder of the continuous casting and cutting machine. The encoder shaft is directly installed on the output shaft of the reducer. Since the output shaft of the reducer and the encoder shaft are closely matched, the areas with more slag, dust, and water vapor on site are mixed with debris under the action of the high temperature environment and enter the gap between the output shaft of the reducer and the encoder shaft, causing the output shaft of the reducer and the encoder shaft to be difficult to separate. Especially when the encoder fails in production and the encoder needs to be replaced urgently, the encoder is difficult to remove due to adhesion, which has a serious adverse effect on the on-site production. Secondly, the encoder lacks effective protection in the high temperature, high water vapor and high dirt environment on site, which affects the effective service life of the encoder. Finally, the on-site encoder cable disassembly and installation wastes working time.

DETAILED DESCRIPTION

[0050] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. The specific structures and functional details disclosed herein are only used to describe the exemplary embodiments of the present invention. However, the present invention can be embodied in many alternative forms, and it should not be understood that the present invention is limited to the embodiments set forth herein.

[0051] like Figures 1 to 4 As shown, according to an embodiment of the present disclosure, an encoder installation device 100 is proposed, including: a protective component 110, wherein a placement space is formed in the protective component 110 for placing an encoder 200, and the protective component 110 is used to be fixed to a reducer 220; a pressure cover component 120, which is covered on the protective component 110 and is used to press and fix the encoder 200 so that the encoder 200 remains in a working position; a coupling portion 130, wherein the output shaft 230 of the reducer 220 is passed through the protective component 110, and the output shaft 230 is connected to the shaft body 210 of the encoder 200 through the coupling portion 130; and a cooling component, which is used to cool the encoder 200.

[0052] It is understandable that the encoder installation device 100 provided in the embodiment of the present disclosure is provided with a protective component 110, a gland component 120, a coupling part 130 and a cooling component. Among them, a placement space is formed in the protective component 110, and the encoder 200 can be placed in the placement space. The gland component 120 is covered on the protective component 110. The gland component 120 and the protective component 110 cooperate to protect the encoder 200, reduce the amount of impurities such as slag, dust and water vapor falling on the encoder 200, and extend the service life of the encoder 200. The protective component 110 is fixed to the reducer 220, and the output shaft 230 of the reducer 220 is passed through the protective component 110, and is connected to the shaft 210 of the encoder 200 through the coupling part 130. The encoder 200 is fixed by pressing the cover assembly 120 to keep the encoder 200 in the working position, and no additional fixing parts are needed to fix the coupling, the shaft body 210 and the output shaft 230, which can also ensure the stability of the connection between the coupling part 130, the shaft body 210 and the output shaft 230, thereby improving reliability. At the same time, the encoder 200 is cooled by the cooling assembly to provide the encoder 200 with a suitable working temperature, thereby reducing the impact of the high temperature environment on the working environment temperature of the encoder 200. By using the protective component 110, the pressure cover component 120, the coupling part 130 and the cooling component in coordination, it is possible to prevent impurities such as residues, dust and water vapor on site from entering the gap between the output shaft 230 of the reducer 220 and the shaft body 210 of the encoder 200, thereby causing the output shaft 230 of the reducer 220 and the shaft body 210 of the encoder 200 to adhere and be difficult to separate. In particular, when the encoder 200 fails during production and needs to be replaced urgently, it is only necessary to remove the pressure cover component 120 to move the encoder 200 away from the working position, thereby facilitating the removal of the encoder 200 from the placement space. The operation is convenient, and the efficiency of removing and replacing the encoder 200 is improved, thereby improving the overall operating efficiency.

[0053] In some examples, such as Figure 1 and Figure 2 As shown, the protective assembly 110 includes: a protective cylinder 111, the top of which is connected to the pressure cover assembly 120; a bottom plate 112, connected to the bottom of the protective cylinder 111, a through hole is provided in the middle of the bottom plate 112, and the output shaft 230 is passed through the through hole; a fixing plate 113, arranged in the protective cylinder 111, for fixing the encoder 200; a limiting column 114, arranged on the inner wall of the protective cylinder 111, a groove is provided on the peripheral side of the fixing plate 113, the fixing plate 113 slides along the axial direction of the limiting column 114 through the groove, and the limiting column 114 is used to limit the rotation of the fixing plate 113; a fixing frame 115, for fixing the protective cylinder 111 to the reducer 220.

[0054] It can be understood that the protection assembly 110 is provided with a protection tube 111, a bottom plate 112, a fixing plate 113, a limiting column 114 and a fixing frame 115. Among them, the top of the protection tube 111 is connected to the gland assembly 120, the bottom plate 112 is connected to the bottom of the protection tube 111, and a through hole is opened in the middle of the bottom plate 112, and the output shaft 230 can be inserted through the through hole and located in the placement space. The fixing plate 113 is arranged in the protection tube 111 to support and fix the encoder 200. The inner side wall of the protection tube 111 is provided with a limiting column 114 along the axial direction. Correspondingly, a groove is opened on the peripheral side of the fixing plate 113, and the fixing plate 113 can slide along the axial direction of the limiting column 114 through the groove. The rotational freedom of the fixing plate 113 is limited by setting the limiting column 114, thereby limiting the rotation of the encoder 200, so that the encoder 200 can only slide up and down to ensure accurate transmission. The protective tube 111 is fixed to the reducer 220 through the fixing frame 115, thereby ensuring the position stability of the encoder installation device 100 and improving reliability.

[0055] In some examples, such as Figure 1 and Figure 2 As shown, a plurality of the limiting posts 114 are provided, and the plurality of limiting posts 114 are axially symmetrically arranged with the central axis of the protective tube 111 as the axis of symmetry, and each of the limiting posts 114 corresponds to one of the grooves.

[0056] It is understandable that there can be multiple limit posts 114, and the multiple limit posts 114 can be arranged axially symmetrically with the central axis of the protective tube 111 as the symmetry axis, and the number of limit posts 114 corresponds to the number of slots, and multiple slots are provided, and the multiple slots can be arranged axially symmetrically with the central axis of the fixed plate 113 as the symmetry axis, so as to ensure that each limit post 114 has a corresponding slot. Such a configuration can ensure uniform force, and the fixed plate 113 can slide stably along the axial direction of the limit post 114, thereby improving reliability.

[0057] Exemplarily, there are two limiting posts 114 and two slots.

[0058] In some examples, such as Figure 1 and Figure 3 As shown, the pressure cover assembly 120 includes: a cover body 121, which is covered on the top of the protective tube 111, and the connector 140 of the cooling assembly passes through the cover body 121 and extends into the placement space; a pressing piece 122, one end of the pressing piece 122 is connected to the cover body 121, and the other end is used to press on the encoder 200.

[0059] It is understandable that the pressure cover assembly 120 is provided with a cover body 121 and a pressing piece 122. Among them, the cover body 121 is covered on the top of the protective tube 111, and the joint 140 of the cooling assembly can extend into the placement space through the cover body 121 to transport cooling airflow to the placement space. One end of the pressing piece 122 is connected to the cover body 121, and when the cover body 121 is installed in place, the encoder 200 can be pressed by the other end of the pressing piece 122. The encoder 200 is kept in the working position by pressing, that is, the coupling part 130 can stably transmit the power of the output shaft 230 to the shaft body 210 of the encoder 200. After the cover body 121 is removed, the pressing piece 122 stops pressing the encoder 200, so that the encoder 200 can be quickly removed and the replacement efficiency is improved.

[0060] In some examples, such as Figure 1 and Figure 3 As shown, a plurality of the pressing members 122 are provided, and the plurality of pressing members 122 are axially symmetrically arranged with the central axis of the cover body 121 as the axis of symmetry.

[0061] It is understandable that there may be multiple pressing members 122, and the multiple pressing members 122 may be arranged axially symmetrically with the central axis of the cover body 121 as the axis of symmetry to ensure uniform distribution of the top pressure on the encoder 200 and improve reliability. Exemplarily, there are two pressing members 122, and the two pressing members 122 are axially symmetrically distributed with the central axis of the cover body 121 as the axis of symmetry.

[0062] In some examples, it further includes: a connector, through which the cover body 121 is connected to the protective tube 111.

[0063] It is understandable that the encoder installation device 100 may also be provided with a connecting piece, through which the cover body 121 is connected to the protective tube 111.

[0064] Exemplarily, the connector may be a spring buckle. Specifically, the spring buckle may be provided at one of the cover body 121 or the protective tube 111, and the buckle position may be provided at the other of the cover body 121 or the protective tube 111, and the positions of the spring buckle and the buckle plate correspond to each other. By buckling the spring buckle at the buckle position to fix the cover body 121 to the protective tube 111, the protective assembly 110 and the pressure cover assembly 120 cooperate to have a stable protective function, and ensure the stable operation of the encoder 200 in the placement space. The cover body 121 is removed by releasing the connection between the spring buckle and the buckle position to install or remove the encoder 200.

[0065] In some examples, such as Figure 1 and Figure 3As shown, the pressing member 122 includes: a sleeve 1221, the top outer wall of the sleeve 1221 is provided with an external thread, and the sleeve 1221 is threadedly connected to the cover body 121; a top screw 1222, the top inner wall of the sleeve 1221 is provided with an internal thread, and the top screw 1222 is threadedly connected to the top inner wall of the sleeve 1221; a rod body 1223, which is passed through the bottom end of the sleeve 1221, and the rod body 1223 is used to slide along the axial direction of the sleeve 1221; an elastic member 1224, which is provided in the inner cavity of the sleeve 1221; a pressing member 1225 is fixedly connected to one end of the rod body 1223 away from the sleeve 1221, and is used for pressing the encoder 200; wherein, when the cover body 121 is connected to the protective tube 111 through the connecting piece, the rod body 1223 drives the pressing piece 1225 to push the encoder 200 to move toward the direction of the bottom plate 112, and the elastic piece 1224 is in a compressed state; when the connecting piece is in a disconnected state, the elastic piece 1224 rebounds to push the cover body 121 and the protective tube 111 to separate.

[0066] It is understandable that the pressing member 122 may be provided with a sleeve 1221, a top screw 1222, a rod 1223, an elastic member 1224 and a top pressing member 1225. The sleeve 1221 is formed with an inner cavity, and the outer wall of the top end of the sleeve 1221 is provided with an external thread, and the top end of the cover body 121 is provided with a threaded hole along the axial direction of the cover body 121, and the external thread can be screwed into the threaded hole to thread the sleeve 1221 and the cover body 121, and the sleeve 1221 is located in the placement space. The inner wall of the top end of the sleeve 1221 is provided with an internal thread, and the external thread of the top screw 1222 is screwed into the internal thread to thread the top screw 1222 and the sleeve 1221. The rod body 1223 can be inserted into the bottom end of the sleeve 1221 and can slide along the axial direction of the sleeve 1221. One end of the rod body 1223 away from the sleeve 1221 is fixedly connected with a pressing piece 1225. An elastic piece 1224 is arranged in the inner cavity of the sleeve 1221. With such arrangement, when installing the encoder 200, the encoder 200 is fixed to the fixing plate 113 and then placed in the protective tube 111, and the cover 121 is placed on the top end of the protective tube 111. The cover 121 drives the rod 1223 to move in the direction close to the encoder 200, so that the rod 1223 drives the pressing member 1225 to move in the direction close to the encoder 200, so that the pressing member 1225 presses the encoder 200, and the encoder 200 and the fixing plate 113 move in the direction close to the coupling part 130 along the axial direction of the limiting column 114, so that the shaft 210 of the encoder 200 and the coupling part 130 are connected in place. The cover 121 is fixed to the protective tube 111 by the connecting member to ensure that the shaft 210 and the coupling part 130 can be stably connected, thereby improving reliability. At this time, the elastic member 1224 is compressed. When the encoder 200 needs to be removed, the connecting piece is adjusted to the disconnected state, and the elastic piece 1224 rebounds without being subjected to pressure to push the cover body 121 to open. The cover body 121 drives the rod body 1223 and the top pressure piece 1225 away from the encoder 200 to facilitate the removal of the encoder 200, thereby improving the disassembly and assembly efficiency of the encoder 200. In addition, since the assembly between the coupling, the shaft body 210 and the output shaft 230 can be completed through the pressure cover assembly 120, there is no need to use fasteners such as fastening bolts as in the related art, thereby further improving the disassembly and assembly efficiency.

[0067] In some examples, such as Figure 1 and Figure 4 As shown, the coupling portion 130 includes: a first coupling 131, used for fixedly connecting to the shaft body 210; a second coupling 132, used for fixedly connecting to the output shaft 230; a positioning pin 133, along the axial direction of the first coupling 131, the first coupling 131 is provided with a first positioning hole, the second coupling 132 is provided with a second positioning hole, the positions of the first positioning hole and the second positioning hole correspond to each other, and the positioning pin 133 is passed through the first positioning hole and the second positioning hole.

[0068] It is understandable that the coupling part 130 is provided with a first coupling shaft 131, a second coupling shaft 132 and a positioning pin 133. The first coupling shaft 131 can be fixedly connected to the shaft body 210 by bolts, so that the first coupling shaft 131 and the shaft body 210 can rotate synchronously. The second coupling shaft 132 can be fixedly connected to the output shaft 230 by bolts, so that the second coupling shaft 132 and the output shaft 230 can rotate synchronously. The first coupling shaft 131 is provided with a first positioning hole, and the second coupling shaft 132 is provided with a second positioning hole. The positions of the first positioning hole and the second positioning hole correspond to each other. The positioning pin 133 is penetrated through the first positioning hole and the second positioning hole, and one end of the positioning pin 133 can be fixedly connected to the first coupling shaft 131 or the second coupling shaft 132. With such a configuration, when the cover assembly 120 presses the encoder 200 to move toward the direction close to the output shaft 230, the shaft body 210 drives the first coupling 131 to move toward the direction close to the second coupling 132, and the positioning pin 133 passes through the first positioning hole until the first coupling 131 and the second coupling 132 are installed in place. The positioning pin 133 restricts the first coupling 131 and the second coupling 132 to only move synchronously, so that the output shaft 230 can drive the coupling part 130 and the shaft body 210 to rotate when it rotates. When the cover body 121 is opened to take out the encoder 200, the shaft body 210 drives the first coupling 131 to move away from the output shaft 230, and the first coupling 131 moves along the positioning pin 133 until it is separated from the positioning pin 133, and the second coupling 132 is separated from the first coupling 131. Thus, the encoder 200 can be quickly removed. The structural form of the coupling part 130 can change with the position of the encoder 200.

[0069] In some examples, such as Figure 1 As shown, it also includes: an aviation plug 150, the female head of the aviation plug 150 is fixedly connected to the cover body 121, and the male head of the aviation plug 150 is used to connect with the cable of the encoder 200.

[0070] It can be understood that the encoder installation device 100 is also provided with an aviation plug 150, which is fixedly connected to the cover body 121 through the female head of the aviation plug 150, and the male head of the aviation plug 150 is connected to the cable of the encoder 200. The aviation plug 150 is used to effectively improve the installation and disassembly operation speed through the plug-in and separation of the male head and the female head.

[0071] In some examples, the cooling component includes: a gas pipeline connected to the placement space through the joint 140; a refrigeration device, the gas pipeline being connected to the refrigeration device; a temperature detection device disposed in the placement space; and a controller for adjusting the operating power of the refrigeration device according to the temperature value detected by the temperature detection device.

[0072] It is understandable that the cooling assembly may be provided with a gas pipeline, a refrigeration device, a temperature detection element and a controller. Specifically, the gas pipeline may be connected to the placement space through the joint 140, and the refrigeration device may deliver cooling gas to the placement space through the gas pipeline to reduce the internal temperature of the placement space. The temperature detection element may detect the internal temperature of the placement space in real time and send the temperature data to the controller. The controller may adjust the operating power of the refrigeration device according to the temperature value detected by the temperature detection element to control the temperature in the placement space within a temperature range suitable for the operation of the encoder 200, thereby improving reliability.
