Description

Technical Field

[0001] The invention belongs to the technical field of metal surface treatment, and in particular relates to a movable shaft seat unit. Background Art

[0002] Steel plates will rust after long-term stacking or use. If they are not treated, the rust damage will be aggravated. In the treatment of rust on the surface of steel, more environmentally friendly brushing methods are constantly being developed and improved.

[0003] The applicant's prior application number CN201910947017.0 discloses a steel plate rust removal production line, in which, in order to achieve grinding and brushing of both the upper and lower surfaces of the steel plate, a descaling roller used for grinding and brushing is installed on a bearing seat located below the working main beam, and the working main beam is connected to the bottom of the upper beam through a worm gear, and the lifting motor drives the lifting mechanism to move, so as to achieve the up and down lifting of the working main beam, thereby driving the descaling roller to lift up and down, so that the descaling roller can be suspended above or below the steel plate to grind the upper and lower surfaces of the steel plate; however, the following problems were found in subsequent processing: 1. When processing incoming materials, the widths of the steel plates to be brushed are different, and the steel plates will produce left and right deviations during grinding and brushing. In order to ensure that the steel plates can be brushed by the descaling roller, the descaling roller The length of the descaling roller is usually larger than the width of the steel plate; if the steel plate itself has a longer width, the length of the descaling roller will be longer, so not only will the weight of the descaling roller increase, but its cross-length will also be longer, which will easily cause shaking and instability during grinding, and will also put a greater load on the bearing seat and the working beam; 2. If the descaling roller is shortened to solve the poor stability problem mentioned in the first point, the brushing on the upper surface of the steel plate can be completed by moving the descaling roller above the steel plate left and right and rotating it circumferentially, but for the descaling roller below the steel plate, since the descaling roller below the steel plate is hung on the frame by two longitudinal beams, when processing a steel plate with a width greater than the length of the descaling roller, the steel plate cannot pass through the middle of the two longitudinal beams, so the processing flexibility is limited.

[0004] Therefore, in subsequent improvements, a steel plate surface treatment device with application number CN202111287159.2, which is convenient for roller changing, was submitted. The upper brush roller and the lower brush roller are respectively arranged at the upper and lower ends of the steel plate to brush the steel plate. The method of hanging the lower brush roller by the longitudinal beam mentioned in the above paragraph is abandoned. Therefore, the length of the brush roller does not need to be greater than the width of the steel plate, and rust removal can be completed by staggered or back-and-forth brushing. The brush roller is connected to the bearing seat through a mounting seat, and the bearing seat can also move relative to the base, which is also convenient for moving the bearing seat out of the upper and lower ends of the steel plate for roller changing after the abrasive is worn.

[0005] Regardless of which of the above patent solutions, the operation is carried out in a water environment, and the abrasive wire of the descaling roller needs to be replaced after the wear and tear of the abrasive wire. The roller replacement operation method has been recorded in the above two patent solutions, but how to waterproof the key components is a difficult point. In the Chinese invention patent, a shaft seat driving device and a descaling roller rust removal device are disclosed. Although the patent focuses on the strengthening locking of the bearing seat, it also mentions waterproofing and chip prevention; the shaft seat driving device includes a base plate, a box body surrounded by the base and the side plates, front baffles and rear baffles recorded in the document, and the box body is a hollow area inside. The bearing seat connected to the movable bearing seat is hoisted under the box body. The hollow area is provided with a cylinder and a guide shaft for driving the bearing seat and the bearing seat to move, so as to prevent splashing water and debris from entering the area during the grinding process; baffles are connected to the bottom of the two side plates, and a partition is provided at the tail end of the bearing seat connected to the guide shaft. When the bearing seat moves to abut against the front baffle, it can cooperate with the bottom plate and the side plate to form a relatively sealed space. However, since the partition and the bottom plate are staggered in the vertical direction, there will still be a gap when forming the above-mentioned relatively sealed space.

[0006] Now, it is planned to combine the principles recorded in the application numbers CN202011638763.0 and CN202111287159.2 to brush the upper and lower surfaces of the steel plate. Although the shaft seat drive device on the upper surface of the steel plate can be arranged as recorded in the application number CN202011638763.0, the shaft seat drive device located on the lower surface of the steel plate needs to be flipped 180 degrees so that the scale breaking roller faces upward, that is, it needs to be arranged inverted under the steel plate to complete the grinding of the upper and lower surfaces of the steel plate.

[0007] However, the problem is that since the grinding and brushing of the steel plate is a water-based operation, although the shaft seat drive device arranged above the steel plate is suspended, it is difficult for water to splash into the shaft seat drive device during the grinding process, but the shaft seat drive device located below the steel plate is inverted, that is, the bottom plate and the partition are facing upward at this time. In the working state, the splashed water will flow into the shaft seat drive device from the gap between the bottom plate and the partition, thereby causing a negative impact, and the waterproofing fails, which violates the original intention of waterproofing. Moreover, the bearing seat 1 for supporting the descaling roller provided in the above-mentioned shaft seat drive device is always exposed to the outside whether it is in the unlocked state or the exposed state. When installing or replacing the descaling roller, it is easy to collide, thereby causing the bearing seat 1 to tilt or loosen. In addition, the replacement of the descaling roller is also relatively frequent during production, which will further increase the occurrence of collisions. Summary of the invention

[0008] In order to solve the above-mentioned technical problems, the purpose of the present invention is to provide a mobile shaft seat unit, in which the brush roller connecting mechanism is retracted when extended inside the bearing box and only extends outward in the working state, thereby protecting the brush roller connecting mechanism; and the bearing box is a welded part as a whole, and the sealed connection between the drive box and the bearing box can also effectively prevent the entry of water. At the same time, when in the extended working state, it can also press against the exposed opening to avoid the entry of water, thereby playing a waterproof role.

[0009] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0010] A movable shaft seat unit, comprising a bearing box arranged on a horizontally movable beam, wherein the bearing box is provided with a brush roller connecting mechanism for connecting a supporting brush roller, wherein the brush roller connecting mechanism comprises a sliding seat that can slide relatively along the length direction of the bearing box and a movable bearing seat connected to the side wall of the sliding seat, wherein the sliding seat and the movable bearing seat are arranged in close proximity to each other along the length direction of the bearing box, and a shaft support device for connecting a brush roller shaft head is provided in the sliding seat and the movable bearing seat; the rear side of the bearing box is also sealedly connected to a drive box with a built-in drive device, wherein the drive device is provided with a The bearing box passes through the rear side wall and its output end is connected to the sliding seat. The interior of the bearing box and the interior of the drive box are separated by the rear side wall of the bearing box to form two independent spaces that do not affect each other. The sliding seat drives the shaft support device to move synchronously through the drive device to dock and install or loosen and replace the brush roller. The front side of the bearing box is also provided with an exposed opening. When working, the movable bearing seat is extended from the exposed opening and is in a sealed state with the exposed opening to prevent water from entering the bearing box. When the brush roller is replaced, the movable bearing seat can be retracted into the bearing box to avoid collision.

[0011] The sliding seat and the movable bearing seat are arranged in the bearing box, and the sliding seat can drive the movable bearing seat to slide, so that the movable bearing seat can extend from the exposed opening to support the brush roller, and can also be retracted from the exposed opening to the bearing box to release the support for the brush roller for easy replacement of the brush roller. Since the brush roller is replaced frequently in production, the sliding seat and the movable bearing seat can be retracted into the bearing box during replacement. At this time, the bearing box has a covering and protective effect on the sliding seat and the movable bearing seat; although the exposed opening will be exposed when the bearing box is retracted, the steel plate is not brushed at this time, and there will be no water or debris splashing. At the same time, the sealing of the movable bearing seat and the exposed opening when working outside also makes the bearing box in a relatively sealed state, and water and debris will not splash into the bearing box. The sealed connection of the drive box can also prevent water and debris from splashing into the drive box, thereby achieving a waterproof effect. At the same time, the drive device passes through the rear wall of the bearing box and acts on the sliding seat. Therefore, the rear wall of the bearing box is used to further prevent water from affecting the drive device. Even if the sealing state with the exposed opening fails when the bearing seat is extended outward, causing water to enter the bearing box, the entering water will be blocked by the rear wall of the bearing box, and water will not enter the drive box.

[0012] Preferably, the shaft support device is located above the central axis of the movable bearing seat to form an eccentric setting, thereby increasing the height of the brush roller so that when the horizontal movement of the beam drives the bearing box to move, the top surface of the bearing box can avoid the steel plate to be polished; the movable bearing seat has an elliptical cross-section and is vertically arranged on the front side of the sliding seat to increase the connection area between the movable bearing seat and the side wall of the sliding seat and the stability of the movable bearing seat when supporting the brush roller.

[0013] The eccentric setting of the mobile bearing seat can increase the height of the brush roller, so that even if the abrasive on the brush roller surface is worn out, the top surface of the bearing box will not interfere with the steel plate when the crossbeam moves horizontally along the width of the steel plate to change the roller. If the brush roller shaft head is installed in the middle of the mobile bearing seat in the traditional way, the height of the brush roller will be reduced, and the height of the steel plate on it will be further reduced when the abrasive on the brush roller surface is worn out. In this way, when the crossbeam moves horizontally to the steel plate surface, it is easy to cause interference between the steel plate and the bearing box.

[0014] Preferably, the shaft support device includes a sleeve inserted into the sliding seat and the movable bearing seat to improve the stability of the connection between the sliding seat and the movable bearing seat, an inner core tube is rotatably connected in the sleeve, the end of the inner core tube has a connecting port for connecting to the brush roller shaft head, the inner core tube extends out of the outer side of the movable bearing seat and the extended end is also sleeved with a brush roller rotating shaft sleeve.

[0015] Since the sleeve and the inner core tube are inserted into both the sliding seat and the movable bearing seat, their axial length is longer than that of traditional gears. Not only is their own strength improved, but inserting them into the sliding seat and the movable bearing seat also makes the connection between the sliding seat and the movable bearing seat more stable.

[0016] Preferably, a pressure ring is provided on the inner wall of the bearing box around the exposed opening, and a pressure interval is formed in the radial direction between the inner ring wall of the pressure ring and the peripheral edge of the exposed opening; a sealing ring located on the side wall of the sliding seat is sleeved on the circumferential surface of the movable bearing seat, and the sealing ring can enter the pressure interval and abut against the side wall of the bearing box at the exposed opening when the movable bearing seat is extended; after the sealing ring is deformed by abutment, its peripheral edge abuts against the inner ring wall of the pressure ring to prevent water from entering the bearing box; the bearing box is provided with a guide hole at the bottom of the exposed opening; in the working state, the guide hole can guide and discharge water splashed onto the sealing ring and the peripheral edge of the exposed opening.

[0017] The pressure ring forms a pressure zone through its inner ring wall and the peripheral edge of the exposed opening. After entering the zone and being pressed, the sealing ring will deform and extend radially outward. The peripheral edge of the deformed sealing ring will also come into pressure contact with the inner ring wall of the pressure ring, thereby improving the sealing effect.

[0018] Preferably, the driving device is an oil cylinder, the piston rod of which passes through the side wall of the bearing box and is connected to the rear side of the sliding seat; the bearing box is also provided with two parallel guide rods along its length direction and spaced apart from the bottom of the bearing box, and the two ends of the guide rods are respectively connected to the front and rear inner walls of the bearing box, the bottom of the sliding seat is mounted on the guide rods and can slide axially along the guide rods, and the sliding seat forms an empty area with the bottom of the bearing box through the installation of the guide rods.

[0019] On the one hand, the guide rod provides a connection point for the sliding seat and can guide the movement of the sliding seat to make the movement of the sliding seat more stable; on the other hand, the distance between the guide rod and the bottom of the bearing box forms an empty area between the sliding seat and the bottom, so that even if water enters the bearing box, it will not contact the guide rod, the sliding seat and the piston rod of the cylinder.

[0020] Preferably, a drainage system is provided at the bottom of the bearing box to discharge water entering the bearing box when the seal fails; the drainage system includes a drainage port opened at the bottom of the bearing box, and a plurality of partition plates are vertically provided on the bottom plate of the bearing box, and the partition plates are arranged at intervals along the length and width directions of the bearing box to form a plurality of water collection intervals for preventing the water entering the bearing box from spreading; the partition plates arranged along the length direction of the bearing box are provided with connecting holes at the bottom to make the water collection intervals in the length direction interconnected; the water entering each water collection interval can flow from the connecting holes to the drainage port for discharge.

[0021] Although the sealing ring and the pressure ring can play a waterproof role, in the actual production process, the sealing ring may be damaged, and water may enter the bearing box without the operator noticing. The setting of the water collection area can make the water entering the bearing box be concentrated in the water collection area where it falls and guided away through the connecting hole, and the water entering will not spread and wet the bottom of the bearing box, thereby ensuring the dryness of other positions. If there is no water collection area formed by the partition plate, even if there is little water entering the bearing box, it will spread at the bottom of the bearing box. In addition, the water collection areas are interconnected in the length direction of the bearing box, but not in the width direction. Even if more water enters, the water will only gather in the water collection area where it falls, and will be drained from the drain port through the connecting hole; it will not spread everywhere and eventually wet the entire inner wall of the bearing box, making the inside of the bearing box an area with high humidity.

[0022] Preferably, the bottom of the bearing box is closely connected to the top surface of the crossbeam to prevent water from entering the bearing box from the bottom, and a drain pipe for draining water entering the bearing box is provided on the crossbeam at a position corresponding to the drain port.

[0023] Fitting the bottom of the bearing box with the top surface of the beam can effectively prevent water from entering the bearing box from the drainage port at the bottom of the bearing box, and a drainage pipe is provided on the beam to drain the water that enters the bearing box in time when the seal fails.

[0024] Preferably, a fixed bearing seat is installed on the crossbeam to cooperate with the movable bearing seat to support the brush roller, and a driving motor for driving the brush roller to rotate is also connected to the side wall of the fixed bearing seat; the upper half of the rear side of the sliding seat is retracted to form an installation interval, and an encoder is arranged in the installation interval so that the bearing box can provide waterproof protection for the encoder, and the connecting end of the encoder passes through the side wall of the sliding seat and is connected to the center position of the end of the inner core tube, so that the encoder can simultaneously monitor the operation of the brush roller and the driving motor; the installation interval can prevent the encoder from touching the rear side wall of the bearing box when the sliding seat slides toward the rear side wall of the bearing box, and an encoder mounting seat for supporting the encoder is connected to the rear side wall of the sliding seat.

[0025] The formation of the installation interval reduces the weight and volume of the sliding seat on the one hand, and provides space for the encoder to avoid on the other hand; the bearing box can also protect the encoder from water; the traditional encoder is only installed on the drive motor, and can monitor whether the drive motor is running and the speed, so as to judge the operation of the brush roller, but if the shaft head of the brush roller is detached during operation, the drive motor will still idle, and the encoder will still send a signal that the equipment is operating normally; but when connected to the inner core tube, it can not only intuitively monitor whether the brush roller is running, but also monitor the operation of the drive motor; whether the drive motor or the brush roller has problems during operation, the encoder can send an alarm signal.

[0026] Preferably, the encoder mounting seat is a tubular structure and is laterally connected to the rear side of the sliding seat along the length direction of the bearing box. The encoder is fixedly connected to the side wall of the encoder mounting seat, and its connecting end extends axially toward the encoder mounting seat through the rear side wall of the sliding seat and is connected to the inner core tube.

[0027] Preferably, the top surface and side walls of the bearing box are provided with inspection openings, and an inspection cover is detachably connected to the inspection opening by bolts, and the side of the inspection cover that is fitted to the bearing box is coated with sealant; the drive box is fitted to the rear side of the bearing box and fixed by screws, and the connection between the drive box and the bearing box is also coated with sealant.

[0028] The provision of the inspection port not only facilitates the initial installation, but also facilitates subsequent repair and maintenance.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The brush roller connection mechanism is arranged in the bearing box, and can be relatively moved in the bearing box to extend or retract. When extending, part of the brush roller connection mechanism is pressed against the exposed position, which can effectively prevent water from entering the interior; and it is only extended in the working state, which can also protect the brush roller connection mechanism and prevent accidental collision during operation;

[0031] 2. The elliptical shape of the bearing seat in the brush roller connection mechanism and the eccentric setting of the inner core tube and the brush roller shaft sleeve used to connect the brush roller increase the height of the brush roller and avoid interference between the steel plate and the top of the bearing box when withdrawing the material. On the other hand, the weight of the brush roller will generate a large downward force, and the elliptical setting not only ensures the connection point between the inner core tube and the brush roller shaft sleeve, but also increases the connection area with the sliding seat, so that when the brush roller is pressed down to produce a prying action, its support effect will be better;

[0032] 3. The setting of the pressure ring further improves the sealing performance of the sealing ring when it abuts, so that water will not directly enter the bearing box. The guide hole can guide the water to be discharged immediately during operation, so that the water will not gather at the exposed position, further ensuring the waterproof performance;

[0033] 4. Even if water enters the bearing box, the water will fall into the water collection area and can be discharged through the connecting hole to the drain outlet to avoid water retention. The drain outlet is opened at the bottom of the bearing box, and the bearing box is installed vertically on the beam, so water will not enter the interior from the drain outlet.

DETAILED DESCRIPTION

[0044] The specific implementation modes of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0045] In this embodiment, a movable shaft seat unit is specifically disclosed, such as Figure 1-9As shown, its specific structure includes a bearing box 1 arranged on a horizontally movable crossbeam 2, wherein the bearing box 1 is provided with a brush roller connecting mechanism 4 for connecting a supporting brush roller 5, wherein the brush roller connecting mechanism 4 includes a sliding seat 401 that can slide relatively along the length direction of the bearing box 1 and a movable bearing seat 402 connected to the side wall of the sliding seat 401, wherein the sliding seat 401 and the movable bearing seat 402 are arranged in close proximity to each other in the front and back directions along the length direction of the bearing box 1, wherein the sliding seat 401 and the movable bearing seat 402 are provided with a shaft support device for connecting the shaft head of the brush roller 5; the rear side of the bearing box 1 is also sealedly connected to a drive box 115 with a built-in drive device, wherein the drive device is provided with a The bearing box 1 passes through the rear side wall and its output end is connected to the sliding seat 401. The interior of the bearing box 1 and the interior of the drive box 115 are isolated by the rear side wall of the bearing box 1 to form two independent spaces that do not affect each other; the sliding seat 401 drives the shaft support device to move synchronously through the drive device to dock and install or loosen and replace the brush roller 5; the front side of the bearing box 1 is also provided with an exposed opening 106. When working, the movable bearing seat 402 is extended from the exposed opening 106 and is in a sealed state with the exposed opening 106 to prevent water from entering the bearing box 1; when the brush roller 5 is replaced, the movable bearing seat 402 can be retracted into the bearing box 1 to avoid collision.

[0046] When in use, the bottom surface of the bearing box 1 is installed correspondingly to the top surface of the beam 2, and the fixed bearing seat 3 is also pre-installed on the beam 1, so that the two can cooperate to connect the shaft heads at both ends of the supporting brush roller 5 respectively, and the above device is arranged below the steel plate feeding; similarly, the above device can also be rotated 180 degrees and arranged inverted above the steel plate feeding route. When the steel plate needs to be brushed, the movement of the brush roller 5 is controlled by turning on and off the driving motor 6 that drives the brush roller 5 to rotate.

[0047] During the grinding and brushing process, water needs to be sprayed on the grinding and brushing part of the steel plate, which can be used to wash away the oxide scale and abrasive debris from the grinding of the steel plate surface, and can also cool down the grinding position to prevent friction overheating from affecting the grinding and brushing effect of the abrasive. Therefore, if water splashes into the bearing box 1 or the drive box 115 during the grinding of the steel plate, it may cause negative effects.

[0048] In order to ensure the waterproof performance of the bearing box 1, the bearing box 1 is formed into an integrated welded piece by the front plate 101, the top plate 103, the bottom plate 104 and the left and right side plates 105, and then the sliding seat 401 and the movable bearing seat 402 are installed in the bearing box 1, and the output end of the driving device installed in the driving box 115 is first passed through the rear plate 102 and then connected to the sliding seat 401, and then the rear plate 102 is tightly connected to the rear side of the welded piece by screws. Similarly, the driving box 115 is also tightly connected to the rear plate 102 by screws, and the joints are coated with sealant to ensure waterproof performance. The driving box 115 is arranged on the rear side of the bearing box 1, on the one hand, it is convenient to install the driving device, and on the other hand, it is to stay away from the brush roller 5. The bearing box 1 first blocks the splashing water, which also provides a certain protection for the driving box 115, but the driving box 115 still needs to have sealing performance. The drive box 115 is formed by welding a connecting top plate 1151, two connecting side plates 1152 and connecting plates located at the bottom and the rear side, and an opening is left at the front side. The drive box 115 forms a closed box body through the connection with the rear plate 102; at the same time, in order to ensure the sealing of the connection, the connecting top plate 1151 extends upward to form a flange 1153, and the flange 1153 can increase the contact area with the rear plate 102. The fitting connection with the rear plate 102 can improve the sealing of the top of the drive box 115. At the same time, the two connecting side plates 1152 also extend forward to the left and right side walls of the rear plate 102 and are fitted and connected thereto, which further ensures the sealing of the drive box 115 when connected to the rear plate 102.

[0049] Since the movable bearing seat 402 needs to extend out of the bearing box 1 and cooperate with the fixed bearing seat 3 to support the brush roller 5, an exposed opening 106 is opened on the front plate 101, that is, the front side of the bearing box 1; the sliding seat 401 can move in the bearing box 1, and the movable bearing seat 402 is closely connected to the side wall of the sliding seat 401, so that the movable bearing seat 402 can extend out from the exposed opening 106, but it should be noted that the movable bearing seat 402 needs to maintain a sealed state with the exposed opening 106 when extending out to prevent water from entering the interior of the bearing box 1. The drive box 115 is sealed and connected to the rear side of the bearing box 1. On the one hand, it is farther away from the water spraying position than the bearing box 1. On the other hand, the bearing box 1 also plays a certain shielding role. Moreover, the driving device inside it is penetrated through the rear wall of the bearing box 1. Therefore, even when the movable bearing seat 402 is extended outward and the sealing state with the exposed opening 106 fails, and water enters the bearing box 1, the water that enters will not enter the drive box 115 to affect the driving device, so the influence is minimized.

[0050] Because this type of brushing method is mainly performed by brushing with the abrasive on the brush roller 5, the frequency of replacing the brush roller 5 is still relatively high. Therefore, the traditional exposed movable bearing seat 402 is prone to collision when changing the roller. The sliding seat 401 and the movable bearing seat 402 in this embodiment are both located in the bearing box 1 when changing the roller, so they can play a good protective role. Although the exposed port 106 is in an exposed state at this time, because brushing is not required at this time, no water spraying is required and no abrasive debris and oxide scale will be generated.

[0051] When brushing the steel plate, if the brush roller 5 is installed in the traditional production method, the brush roller 5 is connected to the middle position of the movable bearing seat 402; but the shaft support device in this embodiment is located at the upper position of the central axis of the movable bearing seat 402 to form an eccentric setting, and the height of the brush roller 5 is increased so that when the horizontal movement of the beam 2 drives the bearing box 1 to move, the top surface of the bearing box 1 can avoid the steel plate to be polished; the movable bearing seat 402 has an elliptical cross-section and is vertically arranged on the front side of the sliding seat 401, so as to increase the connection area between the movable bearing seat 402 and the side wall of the sliding seat 401 and the stability of the movable bearing seat 402 when supporting the brush roller 5.

[0052] If the traditional installation method is used, the height of the brush roller 5 relative to the bearing box 1 will be reduced. As the grinding progresses, the abrasive on the surface of the brush roller 5 is worn, and the difference between the height of the steel plate on which it is ground and the height of the top of the bearing box 1 will gradually decrease. At this time, when the entire crossbeam 2 is moved out from under the steel plate along the width direction of the steel plate, it is easy to cause interference between the steel plate and the top surface of the bearing box 1. However, the eccentric setting of the shaft support device can avoid such a situation. In addition, the elliptical setting of the movable bearing seat 402 can also increase the connection area with the sliding seat 401, thereby improving the stability of the connection; because the weight of the brush roller 5 is heavy, when the movable bearing seat 402 supports the brush roller 5, the brush roller 5 has a prying action on the movable bearing seat 402. If a traditional bearing seat is used, it is easy to shake and be unstable when working after installation. On the one hand, the elliptical setting can provide a connection point when the shaft support device is eccentrically set, and the lower half of the elliptical shape can support the prying action of the brush roller 5, thereby improving stability.

[0053] Although the movable bearing seat 402 can also be arranged in a circular shape and then the shaft support device can be arranged eccentrically, compared with the elliptical shape, the circular shape will occupy more space in the horizontal direction, thereby increasing the volume of the bearing box 1.

[0054] In this embodiment, when the movable bearing seat 402 is installed in the bearing box 1 and extends outward and downward for work, the difference D between the height of the upper end of the movable bearing seat 402 and the height of the top of the bearing box 1 is 4-5cm, preferably 4cm; the height of the highest point of the circumferential surface of the brush roller 5 and the height L of the top of the movable bearing seat 402 are 14-16cm, preferably 14cm, so as to ensure that the top of the bearing box 1 will not interfere with the steel plate.

[0055] The shaft support device includes a sleeve 404 inserted into the sliding seat 401 and the movable bearing seat 402 to improve the stability of the connection between the sliding seat 401 and the movable bearing seat 402. An inner core tube 405 is rotatably connected inside the sleeve 404. The end of the inner core tube 405 has a connecting port 406 for connecting to the shaft head of the brush roller 5. The inner core tube 405 extends out of the outer side of the movable bearing seat 402, and the end extending outward is also sleeved with a brush roller rotating shaft sleeve 403.

[0056] Since the movable bearing seat 402 and the sliding seat 401 in this embodiment are arranged to be closely connected front to back, instead of hanging the movable bearing seat 402 under the sliding seat 401 as in the traditional method, the sleeve 404 is inserted into the movable bearing seat 402 and the sliding seat 401. On the one hand, the length of the sleeve 404 and the inner core tube 405 is made longer, thereby improving the strength of the two themselves; on the other hand, the connection between the movable bearing seat 402 and the sliding seat 401 is made more stable, and the prying of the movable bearing seat 402 by the brush roller 5 is further balanced.

[0057] When the movable bearing seat 402 is extended, the sealing state between the movable bearing seat 402 and the exposed opening 106 is achieved in the following manner: a pressing ring 111 is provided at the position of the inner side wall of the bearing box 1 around the exposed opening 106, and a pressing zone 112 is formed between the inner ring wall of the pressing ring 111 and the peripheral edge of the exposed opening 106 in the radial direction thereof; a sealing ring 113 located on the side wall of the sliding seat 401 is sleeved on the circumferential surface of the movable bearing seat 402, or a flange 411 is connected to the rear end of the movable bearing seat 402, and the sealing ring 113 is It is connected to the side wall of the flange 411; the sealing ring 113 can enter the pressing zone 112 and abut against the side wall of the bearing box 1 at the exposed opening 106 when the bearing seat 402 is extended outward; after the sealing ring 113 is deformed by abutment, its periphery abuts against the inner ring wall of the pressing ring 111 to prevent water from entering the bearing box 1; the bearing box 1 is provided with a guide hole 114 at the bottom of the exposed opening 106; in the working state, the guide hole 114 can guide and discharge the water splashed to the sealing ring 113 and the periphery of the exposed opening 106.

[0058] The sealing ring 113 is made of rubber and has a certain degree of deformation ability. When the movable bearing seat 402 extends from the exposed opening 106 to support the brush roller 5, the sealing ring 113 will also move along with it, and enter the pressing zone 112 during the movement. When pressing against the inner wall of the bearing box 1, the sliding seat 401 and the inner wall of the bearing box 1 will squeeze the sealing ring 113 to deform and extend in the radial direction, thereby abutting against the inner ring wall of the pressing ring 111, further improving the sealing effect.

[0059] The driving device is an oil cylinder 409, the piston rod of which passes through the side wall of the bearing box 1 and is connected to the rear side of the sliding seat 401; the bearing box 1 is also provided with two parallel guide rods 410 along its length direction and spaced apart from the bottom of the bearing box 1, and the two ends of the guide rod 410 are respectively connected to the front and rear inner walls of the bearing box 1, the bottom of the sliding seat 401 is mounted on the guide rod 410 and can slide axially along the guide rod 410, and the sliding seat 401 forms an empty area with the bottom of the bearing box 1 through the installation of the guide rod 410.

[0060] The drive of the oil cylinder 409 will be more stable. The oil cylinder 409 is arranged in the driving box 115, and is relatively independent of the components in the bearing box 1 and cooperates with each other. The piston rod of the oil cylinder 409 passes through the side wall of the bearing box 1, thereby driving the sliding seat 401 to move. The guide rod 410 provides a connection point for the sliding seat 401 on the one hand, making the sliding seat 401 more stable when sliding. On the other hand, it also makes the sliding seat 401 and the movable bearing seat 402 in the air inside the bearing box 1, located above the bottom of the bearing box 1. In actual production, the sealing ring 113 will age and break after long-term use, which may cause the sealing effect to be poor when the movable bearing seat 402 is extended, and water will enter the bearing box 1, but the erected sliding seat 401 and the movable bearing seat 402 will not contact the entering water, and also play a waterproof role. Since the driving box 115 is blocked by the rear side wall of the bearing box 1, it will not enter water and will not be affected.

[0061] The bearing box 1 is also provided with a drainage system at the bottom to discharge water entering the bearing box 1 when the seal fails; the drainage system includes a drainage port 110 opened at the bottom of the bearing box 1, and a plurality of partition plates 107 are vertically provided on the bottom plate of the bearing box 1, and the partition plates 107 are arranged at intervals along the length and width directions of the bearing box 1 to form a plurality of water collection areas 108 for preventing the water entering the bearing box 1 from spreading; the partition plates 107 arranged along the length direction of the bearing box 1 are all provided with connecting holes 109 at the bottom to make the water collection areas 108 in the length direction interconnected; the water entering each water collection area 108 can flow from the connecting holes 109 to the drainage port 110 for discharge.

[0062] The reason for the seal failure may be that the seal ring 113 is aged and broken, or the elasticity fails after multiple pressing, and it cannot return to the original state, which leads to the seal failure when it is pressed again. After the failure, water will enter the bearing box 1. If the seal failure is not discovered in time, more and more water will accumulate in the bearing box 1. At this time, even if the guide rod 410 is installed, the water will eventually submerge the position of the sliding seat 401 and the movable bearing seat 402, resulting in some negative effects.

[0063] The water collecting area 108 formed by the partition plate 107 at the bottom of the bearing box 1 can temporarily accumulate the incoming water. When the water flows in from the exposed opening 106, it will flow into the corresponding water collecting area 108 and be discharged from the drain port 110 under the guidance of the connecting hole 109. The partition plate 107 can block the spread of the incoming water. The water collecting areas 108 in the length direction of the bearing box 1 are interconnected to guide the water out and prevent the water from accumulating in the bearing box 1. The lack of connection in the width direction of the bearing box 1 is to prevent the water in a certain water collecting area 108 from spreading to other water collecting areas 108, so as to maintain a dry environment in other parts.

[0064] If there is no partition plate 107, when water enters the bearing box 1, it will spread to the bottom of the bearing box 1 and wet the entire bottom of the bearing box 1. Even if the amount of water entering is small, it will still spread and wet the bottom of the bearing box 1. After the partition plate 107 is set, the water that enters falls into the corresponding water collection interval 108, and can be discharged from the drain port 110 after flowing through each water collection interval 108 connected in the length direction of the bearing box 1. The drain port 110 can be set in the middle of the bottom surface of the bearing box 1 or close to the exposed port 106, thereby further shortening the water flow path and ensuring the dryness of other positions at the bottom of the bearing box 1. Even if the amount of water entering is large, the partition plate 107 can also block and divert the water, and the connecting hole 109 will guide and drain the water that flows into the corresponding water collection interval 108 in time, so that it will not flow into the water collection interval 108 at other positions, so that the bearing box 1 can maintain a relatively dry environment as much as possible.

[0065] The bottom of the bearing box 1 is closely connected to the top surface of the crossbeam 2 to prevent water from entering the bearing box 1 from the bottom. A drainage pipe for draining the water entering the bearing box 1 is provided on the crossbeam 2 at a position corresponding to the drainage port 110.

[0066] Since the bottom of the bearing box 1 is closely connected to the cross beam 2, it can effectively prevent splashing water from entering the bearing box 1 through the drain port 110 during operation. If the seal of the extended movable bearing seat 402 and the exposed port 106 fails, the water that enters can be discharged from the drain port 110 and further discharged through the drain pipe provided on the cross beam 2, thereby preventing water from accumulating more and more in the bearing box 1.

[0067] Before brushing preparation, the upper rear part of the sliding seat 401 is retracted to form an installation interval, and an encoder 407 is arranged in the installation interval so that the bearing box 1 can provide waterproof protection for the encoder 407. The connection end of the encoder 407 passes through the side wall of the sliding seat 401 and is connected to the center position of the end of the inner core tube 405, so that the encoder 407 can monitor the operation of the brush roller 5 and the drive motor 6 at the same time; the installation interval can prevent the encoder 407 from touching the rear side wall of the bearing box 1 when the sliding seat 401 slides toward the rear side wall of the bearing box 1, and an encoder mounting seat 408 for supporting the encoder 407 is connected to the rear side wall of the sliding seat 401.

[0068] Usually, the steel plate to be brushed is relatively long, so the brush roller 5 needs to be in a state of continuous working. However, during production, the brush roller 5 may be separated from the fixed bearing seat 3 or the mobile bearing seat 402. At this time, the brush roller 5 is no longer brushing the steel plate. However, it is impossible to manually observe whether the brush roller 5 is running during the brushing process. Therefore, an encoder 407 is usually provided for monitoring.

[0069] In the traditional way, the encoder 407 is installed on the drive motor 6, and the operating status of the brush roller 5 is deduced by monitoring whether the drive motor 6 is running and the speed. However, the problem is that if the brush roller 5 still detaches at this time, the drive motor 6 will not stop running and will idle, but the situation monitored by the encoder 407 is still in a normal operating state; only when the drive motor 6 fails and stops running, can the encoder 407 detect that it is in an abnormal state and then send a signal.

[0070] In this embodiment, the encoder 407 is connected to the inner core tube 405. If the brush roller 5 is detached at this time, the brush roller 5 must be in a non-working state, and the encoder 407 can monitor the occurrence of such a situation. If the brush roller 5 stops rotating due to a failure of the drive motor 6, the encoder 407 can also monitor the abnormal situation and send a signal. In addition, the encoder 407 is exposed to the outside in the traditional method, while in this embodiment, it is located inside the bearing box 1, which is not only waterproof but also prevents collision. The setting of the installation interval provides the space required for the connection of the encoder 407, and also ensures that the encoder 407 will not touch the inner wall of the bearing box 1 when the sliding seat 401 slides to the rear side; on the other hand, it also reduces the weight of the sliding seat 401.

[0071] The encoder mounting seat 408 is a tubular structure and is laterally connected to the rear side of the sliding seat 401 along the length direction of the bearing box 1. The encoder 407 is fixedly connected to the side wall of the encoder mounting seat 408, and its connecting end extends axially toward the encoder mounting seat 408, passes through the rear side wall of the sliding seat 401 and is connected to the inner core tube 405.

[0072] The top surface and side wall of the bearing box 1 are both provided with inspection openings, and an inspection cover plate 116 is detachably connected to the inspection opening by bolts. The side of the inspection cover plate 116 that is closely connected to the bearing box 1 is coated with sealant.

[0073] Any equipment may be damaged and need repair and maintenance under continuous operation. The inspection port is set to facilitate operators to inspect the components inside the bearing box 1. The applied sealant is to prevent water splashed during the grinding process from entering the interior through the gap between the inspection cover 116 and the bearing box 1.

[0074] The above contents described in this specification are merely examples of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, as long as they do not deviate from the contents of the present specification or exceed the scope defined by the claims, they shall all fall within the protection scope of the present invention.
