Description of the embodiments

The following describes the embodiments of the present invention in detail with reference to the drawings.

In this embodiment, as shown in fig. 1-9, the specific structure of the waterproof bearing box for connecting a brush roller is disclosed, the waterproof bearing box comprises a bearing box body 1 arranged on a horizontal movable cross beam 2, a brush roller connecting mechanism 4 for connecting and supporting a brush roller 5 is arranged in the bearing box body 1, the brush roller connecting mechanism 4 comprises a sliding seat 401 capable of sliding relatively along the length direction of the bearing box body 1 and a movable bearing seat 402 connected on the side wall of the sliding seat 401, the sliding seat 401 and the movable bearing seat 402 are arranged in a front-back laminating way along the length direction of the bearing box body 1, and shaft support devices for connecting shaft heads of the brush roller 5 are arranged in the sliding seat 401 and the movable bearing seat 402 in a penetrating manner; the rear side of the bearing box body 1 is also in sealing connection with a driving box 115 internally provided with a driving device, the driving device penetrates through the rear side wall of the bearing box body 1, the output end of the driving device is connected with a sliding seat 401, and two independent spaces which are not influenced by each other are formed between the interior of the bearing box body 1 and the interior of the driving box 115 through the isolation of the rear side wall of the bearing box body 1; the sliding seat 401 drives the shaft support device to synchronously move through the driving device so as to carry out butt joint installation or loose replacement on the brush roller 5; the front side of the bearing box body 1 is also provided with a working port 106, and when in working, the movable bearing seat 402 extends out of the working port 106 and is in a sealing state with the working port 106 so as to prevent water from entering the bearing box body 1; in the state of replacing the brush roller 5, the movable bearing housing 402 can be retracted into the bearing housing body 1 to avoid collision.

When in use, the bottom surface of the bearing box body 1 is correspondingly and in fit with the top surface of the cross beam 2, and the fixed bearing seat 3 is also pre-installed on the cross beam 1, so that the two bearing boxes are matched and can be respectively connected with the shaft heads at the two ends of the bearing brush roller 5, and the device is arranged below the steel plate feed; the device can be rotated 180 degrees and inversely arranged above the steel plate feeding route, and when the steel plate needs to be brushed, the action of the brush roller 5 is controlled by starting and closing the driving motor 6 for driving the brush roller 5 to rotate.

Because the in-process of operation is brushed to the steel sheet, need to spray water to the position that the steel sheet was brushed, be used for washing off the oxide skin that the steel sheet surface was polished down and abrasive material piece of wearing and tearing on the one hand, on the other hand also can cool down the position of polishing, prevent that friction from overheated influences the brush effect of abrasive material. Whereby water may be sprayed into the bearing housing body 1 or the drive housing 115 during the grinding of the steel plate, which may have a negative effect.

In order to ensure the waterproof performance of the bearing box body 1, the bearing box body 1 is formed by a front plate 101, a top plate 103, a bottom plate 104 and left and right side plates 105 into an integrated welding piece, then a sliding seat 401 and a movable bearing seat 402 are installed in the bearing box body 1, an output end of a driving device installed in a driving box 115 firstly penetrates through a rear plate 102 and is connected with the sliding seat 401, then the rear plate 102 is tightly connected to the rear side of the welding piece through a screw, and similarly the driving box 115 is tightly connected to the rear plate 102 through the screw, and sealing glue is coated at the splicing position to ensure the waterproof performance. The drive housing 115 is arranged at the rear side of the bearing housing body 1, on the one hand for easy installation of the drive device and on the other hand for distance from the brush roller 5, the bearing housing body 1 firstly blocks the sputtered water, which also protects the drive housing 115 to some extent, but the drive housing 115 still needs to have sealing properties. Wherein the driving box 115 is formed by integrally welding a connecting top plate 1151, two connecting side plates 1152 and connecting plates positioned at the bottom and the rear side, and an opening is reserved at the front side, and the driving box 115 forms a closed box body through the connection with the rear plate 102; meanwhile, in order to ensure the tightness of connection, the connection top plate 1151 extends upwards to form a flanging 1153, the flanging 1153 can improve the contact area with the rear plate 102, the joint connection with the rear plate 102 can improve the tightness of the top of the driving box 115, and meanwhile, the two connection side plates 1152 also extend forwards to the left and right side walls of the rear plate 102 and are joint-connected with the left and right side walls of the rear plate 102, so that the sealing of the driving box 115 when being connected with the rear plate 102 is further ensured.

The movable bearing seat 402 needs to extend out of the bearing box body 1 to cooperate with the fixed bearing seat 3 to support the brush roller 5, so that a working opening 106 is formed on the front plate 101, namely, the front side of the bearing box body 1; the sliding seat 401 can move in the bearing housing body 1, and the movable bearing seat 402 is attached to the side wall of the sliding seat 401, so that the movable bearing seat 402 can extend outwards from the working opening 106, but it should be noted that the movable bearing seat 402 needs to maintain a sealing state with the working opening 106 when extending outwards, so as to prevent water from entering the interior of the bearing housing body 1. The driving box 115 is connected to the rear side of the bearing box body 1 in a sealing way, on one hand, the position of the driving box is farther from the water spraying position than the bearing box body 1, and on the other hand, the bearing box body 1 also plays a certain shielding role; and the driving device inside the bearing box body 1 is arranged on the rear side wall of the bearing box body 1 in a penetrating way, so that even if the sealing state of the bearing box body 1 with the working port 106 fails when the movable bearing seat 402 extends outwards, the entering water can not enter the driving box 115 to influence the driving device, and the influence is minimized.

Because the brushing mode is mainly to brush the brush roller 5 by the abrasive, the frequency of replacing the brush roller 5 is higher, so that the traditional exposed movable bearing seat 402 is easy to collide during roller replacement, and the sliding seat 401 and the movable bearing seat 402 in the embodiment are positioned in the bearing box body 1 in the roller replacement state, so that the protection effect can be good, and although the working opening 106 is in the exposed state, because the brush is not required at this time, no abrasive fragments and oxide skin are generated due to no spraying water.

When the steel plate is brushed, if the brush roller 5 is installed in the traditional production mode, the brush roller 5 is connected to the middle position of the movable bearing seat 402; however, the bearing support device in the embodiment is located at the position close to the central axis of the movable bearing seat 402 to form eccentric arrangement, so that the height of the brush roller 5 is increased, and when the cross beam 2 moves horizontally to drive the bearing box body 1 to act, the top surface of the bearing box body 1 can avoid a steel plate to be polished; the cross section of the movable bearing seat 402 is elliptical and vertically arranged on the front side of the sliding seat 401, so as to improve 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 in supporting the brush roller 5.

If the height of the brush roller 5 relative to the bearing box body 1 is reduced according to the traditional installation mode, after the abrasive on the surface of the brush roller 5 is worn, the difference between the height of the polished steel plate and the height of the top of the bearing box body 1 is gradually reduced, at this time, when the whole cross beam 2 moves out of the lower part of the steel plate along the width direction of the steel plate, interference obstruction is easily generated between the steel plate and the top surface of the bearing box body 1, but the eccentric arrangement of the axle bracket device can avoid the occurrence of the situation. In addition, the elliptical arrangement of the movable bearing seat 402 can also improve the connection area with the sliding seat 401, thereby improving the connection stability; because the weight of the brush roller 5 is heavy, when the movable bearing block 402 supports the brush roller 5, the brush roller 5 has a prying action on the movable bearing block 402, and if the conventional bearing block is adopted to work after installation, the shaking instability is easy to occur. The oval upper half part can provide the point of connection when the shaft support device is eccentrically arranged, and the oval lower half part can support the prying action of the brush roller 5, so that the stability is improved.

Although the movable bearing seat 402 may be configured in a circular shape, and then the bearing device is configured eccentrically, the circular shape occupies more space in the horizontal direction than the elliptical shape, so that the volume of the bearing housing body 1 is increased.

In this embodiment, when the movable bearing block 402 is mounted on the bearing box body 1 and extends out, the difference D between the height of the upper end of the movable bearing block 402 and the height of the top of the bearing box body 1 is 4-5cm, preferably 4cm; the height of the highest point of the circumference of the brush roll 5 and the height L of the top of the movable bearing seat 402 are 14-16cm, preferably 14cm, so that the top of the bearing box body 1 can be ensured not to interfere with the steel plate.

The bearing support device further comprises a sleeve 404 penetrating through the sliding seat 401 and the moving bearing seat 402 to improve the connection stability of the sliding seat 401 and the moving bearing seat 402, an inner core barrel 405 is rotatably connected to the sleeve 404, a connecting port 406 for connecting a shaft head of the brush roller 5 is formed at the end of the inner core barrel 405, and the end, which extends out of the moving bearing seat 402 and extends out of the inner core barrel 405, is also sleeved with a brush roller rotating shaft sleeve 403.

Because the movable bearing seat 402 and the sliding seat 401 are arranged in a front-back joint manner in the embodiment, unlike the traditional mode in which the movable bearing seat 402 is hung below the sliding seat 401, the sleeve 404 is arranged in the movable bearing seat 402 and the sliding seat 401 in a penetrating manner, so that the lengths of the sleeve 404 and the inner core barrel 405 are longer on one hand, and the strength of the sleeve 404 and the inner core barrel 405 is improved; on the other hand, the connection between the movable bearing seat 402 and the sliding seat 401 is more stable, and the prying of the brush roller 5 on the movable bearing seat 402 is further balanced.

The sealing with working port 106 when movable bearing housing 402 is extended is accomplished by: an annular abutting part 111 is arranged on the inner side wall of the bearing box body 1 around the working opening 106, and an abutting section 112 is formed between the inner annular wall of the abutting part 111 and the periphery of the working opening 106 in the radial direction; the circumference of the movable bearing seat 402 is sleeved with an elastic sealing element 113 positioned on the side wall of the sliding seat 401, the elastic sealing element 113 can be a rubber sealing ring, or the tail end of the movable bearing seat 402 is connected with a flange 411, and the elastic sealing element 113 is connected on the side wall of the flange 411; the elastic sealing element 113 can enter the pressing section 112 and is abutted against the side wall of the bearing box body 1 at the position of the working opening 106 when the movable bearing seat 402 extends outwards; the periphery of the elastic sealing piece 113 is abutted against the inner annular wall of the abutting part 111 after abutting deformation so as to prevent water from entering the bearing box body 1; the bottom of the bearing box body 1 at the working port 106 is provided with an outflow hole 114; in the operating state, the outflow hole 114 guides and discharges water splashed to the peripheral positions of the elastic sealing member 113 and the operating port 106.

The elastic sealing member 113 is made of rubber and has a certain deformability. When the movable bearing seat 402 extends out of the working opening 106 to support the brush roller 5, the elastic sealing member 113 moves together with the movable bearing seat, and enters the pressing section 112 in the moving process, and when the movable bearing seat presses against the inner side wall of the bearing box body 1, the sliding seat 401 and the inner side wall of the bearing box body 1 squeeze the elastic sealing member 113 to deform and extend along the radial direction, so that the elastic sealing member is pressed against the inner annular wall of the abutting portion 111, and the sealing effect is further improved.

The driving device is an oil cylinder 409, and a piston rod of the oil cylinder 409 penetrates through the side wall of the bearing box body 1 and is connected to the rear side of the sliding seat 401; two parallel guide rods 410 which are spaced from the bottom of the bearing box body 1 are further arranged in the bearing box body 1 along the length direction of the bearing box body 1, two ends of each guide rod 410 are respectively connected to the front inner side wall and the rear inner side wall of the bearing box body 1, the bottom of each sliding seat 401 is erected on each guide rod 410 and can axially slide along each guide rod 410, and an empty area is formed between each sliding seat 401 and the bottom of the bearing box body 1 through the erection of each guide rod 410.

The driving of the oil cylinder 409 is more stable, the oil cylinder 409 is arranged in the driving box 115 and is relatively independent and mutually matched with components in the bearing box body 1, a piston rod of the oil cylinder 409 penetrates through the side wall of the bearing box body 1 and can drive the sliding seat 401 to move, the guide rod 410 provides a point for connecting the sliding seat 401 on one hand, the sliding seat 401 is more stable when sliding, and the sliding seat 401 and the movable bearing seat 402 are in a high-altitude state in the bearing box body 1 and are located above the bottom of the bearing box body 1 on the other hand. In actual production, the elastic sealing member 113 may be aged and broken after long-term use, so that the sealing effect may be poor when the movable bearing seat 402 extends outwards, water may enter the bearing housing body 1, but the erected sliding seat 401 and the movable bearing seat 402 may not contact the entering water, and the waterproof effect is also achieved. The blocking of the driving box 115 by the rear side wall of the bearing box body 1 can not enter water and is not affected.

A drainage system is further arranged at the bottom position in the bearing box body 1 so as to drain water entering the bearing box body 1 when the sealing fails; the drainage system comprises a water outlet 110 formed at the bottom of the bearing box body 1, wherein a plurality of partition plates 107 are further vertically arranged on the bottom plate in the bearing box body 1, and the partition plates 107 are distributed at intervals along the length and width directions of the bearing box body 1 so as to form a plurality of water collecting sections 108 for preventing water entering the bearing box body 1 from spreading; the bottoms of the partition plates 107 arranged along the length direction of the bearing housing body 1 are provided with communication holes 109 so that the water collecting sections 108 in the length direction are mutually communicated; water entering each water collecting section 108 can be discharged from the communication hole 109 toward the water discharge port 110.

The reason for the seal failure may be due to aged breakage of the elastic seal 113 or elastic failure after a plurality of pressing, failing to return to the original state, thereby causing seal failure when pressing again for sealing. After failure, water can enter the bearing box body 1, if the sealing failure cannot be found timely, more and more water can be accumulated in the bearing box body 1, and even if the guide rod 410 is erected at this time, the final water can be immersed into the positions of the sliding seat 401 and the movable bearing seat 402, so that negative effects are generated.

The water collection space 108 formed by the partition plate 107 at the bottom of the bearing housing body 1 temporarily accumulates the water entering, and when the water flows in from the working port 106, the water flows into the corresponding water collection space 108, and is discharged from the water discharge port 110 under the guide of the communication hole 109. The partition plate 107 can block the spread of the incoming water, the water collecting sections 108 in the length direction of the bearing housing body 1 are mutually communicated to guide out the water, so that the water is prevented from accumulating in the bearing housing body 1 all the time, and the water entering a certain water collecting section 108 is prevented from spreading to other water collecting sections 108 by not being communicated in the width direction of the bearing housing body 1, so that the drying environment of other parts can be maintained.

If the partition plate 107 is not provided, when water enters the bearing box body 1, the water can spread out from the bottom in the bearing box body 1 to wet the bottom of the whole bearing box body 1, and even if the water amount entering is small, the water can still spread out to wet the bottom in the bearing box body 1; after the partition plate 107 is arranged, the entering water falls into the corresponding water collecting interval 108, and can flow through each water collecting interval 108 communicated with the length direction of the bearing box body 1 and then be discharged from the water outlet 110, and the water outlet 110 can be arranged in the middle of the bottom surface of the bearing box body 1 or at a position close to the working port 106, so that the water flowing stroke is further shortened, and the drying of other positions in the bottom of the bearing box body 1 is ensured; even if the amount of water entering is large, the partition plate 107 can block and split, and the communication hole 109 can guide and drain the water flowing into the corresponding water collecting section 108 in time, so that the water cannot flow into the water collecting section 108 at other positions, and the bearing box body 1 is kept in a relatively dry environment as much as possible.

The bottom of the bearing box body 1 is attached and connected to the top surface of the cross beam 2 to prevent water from entering the bearing box body 1 from the bottom of the bearing box body 1, and a drain pipe for guiding out the water entering the bearing box body 1 is arranged at the position of the cross beam 2 corresponding to the water outlet 110.

Because the bottom of the bearing box body 1 is attached to the cross beam 2, water sputtered in the working state can be effectively prevented from entering the bearing box body 1 through the water outlet 110, and if the sealing between the overhanging movable bearing seat 402 and the working opening 106 fails, the entering water can be further led out through a drain pipe arranged on the cross beam 2 after being discharged from the water outlet 110, so that more water is prevented from accumulating in the bearing box body 1.

Before the preparation of the brush, the upper part of the rear side of the sliding seat 401 is contracted to form an installation section, an encoder 407 is arranged in the installation section so that the bearing box body 1 can carry out waterproof protection on the encoder 407, and the connecting end of the encoder 407 penetrates through the side wall of the sliding seat 401 to be connected with the center position of the end part of the inner core barrel 405, so that the encoder 407 can monitor the operation of the brush roller 5 and the driving motor 6 simultaneously; the mounting section can prevent the encoder 407 from touching the rear side wall of the bearing housing body 1 when the sliding seat 401 slides toward the rear side wall of the bearing housing body 1, and the encoder mounting seat 408 for supporting the encoder 407 is connected to the rear side wall of the sliding seat 401.

The length of the steel plate to be brushed is usually long, so that the brush roller 5 needs to be in a continuous working state, but in the production process, the condition that the brush roller 5 is separated from the fixed bearing seat 3 or the movable bearing seat 402 occurs, at this time, the brush roller 5 is not brushing the steel plate, but in the brushing process, whether the brush roller 5 runs or not cannot be observed all the time by manpower is not possible, so that an encoder 407 is usually arranged for monitoring.

In the conventional manner, the encoder 407 is mounted on the driving motor 6, and the running state of the brush roller 5 is deduced by monitoring whether the driving motor 6 runs and how much the rotation speed is, but there is a problem in that if the brush roller 5 is still separated at this time, the driving motor 6 will not stop running and idle running, but the situation monitored by the encoder 407 is still in the normal running state; only if the driving motor 6 fails to stop operating, the encoder 407 can detect that the driving motor is in an abnormal state and then send a signal.

In this embodiment, the encoder 407 is connected to the inner core barrel 405, and if the brush roll 5 is detached at this time, the brush roll 5 is definitely in a non-working state, the encoder 407 can detect such a situation, if the brush roll 5 is stopped due to the failure of the driving motor 6, the encoder 407 can also detect an abnormal situation, thereby sending a signal. The encoder 407 is exposed in the conventional manner, and in this embodiment, is located inside the bearing housing body 1, so that it is not only waterproof but also collision-proof. The arrangement of the installation interval provides the space for connecting the encoder 407, so that the encoder 407 does not touch the inner side wall of the bearing box body 1 when the sliding seat 401 slides to the rear side; on the other hand, the weight of the sliding seat 401 is reduced.

The encoder mounting seat 408 is in a cylindrical structure and is transversely connected to the rear side of the sliding seat 401 along the length direction of the bearing housing body 1, the encoder 407 is fixedly connected to the side wall of the encoder mounting seat 408, and the connecting end of the encoder mounting seat extends axially towards the encoder mounting seat 408 and penetrates through the rear side wall of the sliding seat 401 to be connected with the inner core barrel 405.

The top surface and the side wall of the bearing box body 1 are provided with an access hole, an access cover plate 116 is detachably connected to the position of the access hole through bolts, and the side surface, which is attached to and connected to the bearing box body 1, of the access cover plate 116 is coated with sealant.

Any equipment is under continuous operation, and the damage can occur and repair and maintenance are needed, and the setting of access port is convenient for operating personnel to overhaul the inside part of bearing box body 1, and the water that the coating is in order to prevent to grind the in-process sputtering enters into inside from the gap of access cover 116 and bearing box body 1.

The foregoing description of the invention is merely exemplary of the invention. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions, without departing from the scope of the invention as defined in the accompanying claims.
