Detailed Description
The following describes a detailed embodiment of the present invention with reference to the accompanying drawings.
In the embodiment, a brush roll spindle head connecting and supporting structure and a steel plate grinding and brushing mechanism using the structure are specifically disclosed, as shown in fig. 1-9, the structure specifically comprises a bearing box 1 arranged on a horizontally movable beam 2, a brush roll connecting mechanism 4 for connecting and supporting a brush roll 5 is arranged in the bearing box 1, the brush roll connecting mechanism 4 comprises a bearing seat 401 capable of relatively sliding along the length direction of the bearing box 1 and a movable bearing seat 402 connected to the side wall of the bearing seat 401, the bearing seat 401 and the movable bearing seat 402 are arranged in a front-back fit manner along the length direction of the bearing box 1, and a bearing device for connecting the spindle head of the brush roll 5 penetrates through the bearing seat 401 and the movable bearing seat 402; the rear side of the bearing box 1 is also hermetically connected with a driving box 115 internally provided with a driving device, the driving device penetrates through the rear side wall of the bearing box 1, the output end of the driving device is connected and acts on the bearing seat 401, and the inside of the bearing box 1 and the inside of the driving box 115 form two independent spaces which are not mutually influenced through the isolation of the rear side wall of the bearing box 1; the bearing seat 401 drives the shaft supporting device to synchronously move through the driving device to carry out butt joint installation or loosening and replacement on the brush roller 5; the front side of the bearing box 1 is also provided with an exposed opening 106, and when the bearing box works, the movable bearing pedestal 402 is in a sealing state with the exposed opening 106 when extending out of the exposed opening 106, so as to prevent water from entering the bearing box 1; in the state of replacing the brush roller 5, the movable bearing housing 402 can be retracted into the bearing housing 1 to avoid collision.
When in use, the bottom surface of the bearing box 1 is correspondingly attached to the top surface of the beam 2, the fixed bearing seat 3 is also pre-installed on the beam 1, so that the two are matched to be respectively connected with the shaft heads at two ends of the bearing brush roller 5, and the device is arranged below the steel plate feeding; in the same way, the device can be rotated by 180 degrees and arranged upside down 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 turning on and off the driving motor 6 for driving the brush roller 5 to rotate.
Because the in-process of the scrubbing operation, need to spray water to the position of steel sheet scrubbing, be used for washing away the cinder that the steel sheet surface was polished and the abrasive material piece of wearing and tearing on the one hand, on the other hand also can cool down the position of polishing, prevents that the rubbing effect of abrasive material is influenced to the overheated friction. This may have a negative effect if water is splashed into the bearing housing 1 or the drive housing 115 during the steel plate grinding process.
In order to ensure the waterproof performance of the bearing box 1, the bearing box 1 is a welding part formed by a front plate 101, a top plate 103, a bottom plate 104, a left side plate 105 and a right side plate 105, then a bearing seat 401 and a movable bearing seat 402 are installed in the bearing box 1, the output end of a driving device installed in a driving box 115 firstly penetrates through a rear plate 102 and then is connected with the bearing seat 401, then the rear plate 102 is tightly connected to the rear side of the welding part through screws, similarly, the driving box 115 is also tightly connected to the rear plate 102 through screws, and the splicing part is coated with sealant to ensure the waterproof performance. The driving box 115 is arranged at the rear side of the bearing box 1, on one hand, the driving device is convenient to install, on the other hand, the driving device is far away from the brush roller 5, the bearing box 1 firstly blocks the splashed water, so that the driving box 115 is protected to a certain extent, but the driving box 115 still needs to have sealing performance. 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, an opening is reserved at the front side, and the driving box 115 is connected with the rear plate 102 to form a closed box body; meanwhile, in order to ensure the connection tightness, the connecting top plate 1151 extends upwards to form a flange 1153, the flange 1153 can increase the contact area with the rear plate 102, the sealing property of the top of the driving box 115 can be improved by the attaching connection with the rear plate 102, and the two connecting side plates 1152 also extend forwards to the left side wall and the right side wall of the rear plate 102 and are attached to the left side wall and the right side wall, so that the sealing property of the driving box 115 and the rear plate 102 is further ensured.
The movable bearing pedestal 402 needs to extend out of the bearing box 1 to be matched with the fixed bearing pedestal 3 to support the brush roller 5, so that an exposed opening 106 is formed in the front plate 101, namely the front side of the bearing box 1; the bearing housing 401 is movable in the bearing housing 1, and the movable bearing housing 402 is attached to the sidewall of the bearing housing 401, so that the movable bearing housing 402 can extend out of the exposed opening 106, but it should be noted that the movable bearing housing 402 needs to maintain a sealing state with the exposed opening 106 when extending out, so as to prevent water from entering the inside of the bearing housing 1. The driving box 115 is hermetically connected to the rear side of the bearing box 1, so that on one hand, the position far away from the water spray is farther than that of the bearing box 1, and on the other hand, the bearing box 1 also plays a certain shielding role; and the driving device inside the bearing box is arranged on the rear side wall of the bearing box 1 in a penetrating way, so even if the sealing state between the movable bearing seat 402 and the exposed opening 106 fails when the movable bearing seat extends outwards, the bearing box 1 is filled with water, and the entered water cannot enter the driving box 115 to influence the driving device, so that the influence is minimized.
Because the grinding and brushing mode is mainly to grind and brush through the abrasive on the brush roller 5, the frequency of replacing the brush roller 5 is still high, so the traditional exposed movable bearing seat 402 is easy to collide when the roller is replaced, and the bearing seat 401 and the movable bearing seat 402 in the embodiment are both positioned in the bearing box 1 in the roller replacing state, so that the roller can play a good role in protection, and although the exposed opening 106 is in the exposing state, the grinding and brushing are not needed at the moment, so that abrasive scraps and oxide scales cannot be generated without 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 block 402; however, the axle support device in this embodiment is located near the upper position of the central axis of the movable bearing block 402 to form an eccentric arrangement, and the height of the brush roller 5 is increased, so that when the cross beam 2 moves horizontally to drive the bearing box 1 to act, the top surface of the bearing box 1 can avoid a steel plate to be polished; the section of the movable bearing seat 402 is oval and is vertically arranged on the front side of the bearing seat 401, so that the connection area of the movable bearing seat 402 and the side wall of the bearing seat 401 is increased, and the stability of the movable bearing seat 402 when the brush roller 5 is supported is improved.
If according to traditional mounting means, the brush roll 5 can reduce for the height of bearing box 1, along with the going on of polishing, the abrasive wear back on brush roll 5 surface, the height difference that the height that the steel sheet that polishes on it was located and the top of bearing box 1 was located can reduce gradually, when moving whole crossbeam 2 below the steel sheet along the steel sheet width direction this moment, makes steel sheet and bearing box 1 top surface produce the interference and hinders very easily, but the eccentric settings of axle bracket device then can avoid the emergence of this type of condition. In addition, the elliptical arrangement of the movable bearing seat 402 can also increase the connection area with the bearing seat 401, thereby improving the connection stability; because the weight of brush roll 5 is heavier, when removing bearing frame 402 and supporting brush roll 5, brush roll 5 has the action of prizing to removing bearing frame 402, if adopt traditional bearing frame when carrying out the during operation after the installation, takes place the unstable condition of shake easily. And the oval upper half part can provide the point location of connecting when axle bracket device eccentric settings on the one hand of oval setting, and oval lower half part then can play the support to the prying action of brush roll 5, improves stability.
Although the movable bearing seat 402 can be arranged in a circular shape and then the bearing support device is arranged eccentrically, compared with the elliptical shape, the circular shape occupies more space in the horizontal direction, so that the volume of the bearing box 1 is increased.
In this embodiment, when the movable bearing block 402 is mounted in the bearing housing 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 housing 1 is 4-5cm, preferably 4cm; the height of the brush roller 5 at the highest point of the circumferential surface 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 1 can not generate interference obstruction with the steel plate.
The axle support device further comprises a fixed cylinder 404 arranged in the bearing seat 401 and the movable bearing seat 402 in a penetrating mode so as to improve the connection stability of the bearing seat 401 and the movable bearing seat 402, a rotating core 405 is connected in the fixed cylinder 404 in a rotating mode, a connecting port 406 used for connecting a shaft head of the brush roll 5 is arranged at the end portion of the rotating core 405, and a brush roll rotating shaft sleeve 403 is sleeved at the end portion, extending out of the movable bearing seat 402, of the rotating core 405.
Because the movable bearing seat 402 and the bearing seat 401 in this embodiment are attached and connected in the front-back direction, unlike the conventional method in which the movable bearing seat 402 is suspended below the bearing seat 401, the fixed cylinder 404 is inserted into the movable bearing seat 402 and the bearing seat 401, on one hand, the lengths of the fixed cylinder 404 and the rotating core 405 are longer, and the strengths of the fixed cylinder 404 and the rotating core 405 are further improved; on the other hand, the connection between the movable bearing seat 402 and the bearing seat 401 is more stable, and the prying of the brush roller 5 on the movable bearing seat 402 is further balanced.
The sealing state between the movable bearing seat 402 and the exposed opening 106 when extending is realized by the following steps: the inner side wall of the bearing box 1 is provided with a pressing ring 111 at the position surrounding the exposed opening 106, and a pressing section 112 is formed between the inner annular wall of the pressing ring 111 and the periphery of the exposed opening 106 in the radial direction; the circumferential surface of the movable bearing seat 402 is sleeved with a sealing ring 113 positioned on the side wall of the bearing seat 401, or the tail end of the movable bearing seat 402 is connected with a flange 411, and the sealing ring 113 is connected on the side wall of the flange 411; when the movable bearing seat 402 extends outward, the sealing ring 113 can enter the abutting section 112 and abut against the side wall of the bearing box 1 at the position of the exposed opening 106; the periphery of the sealing ring 113 abuts against the inner annular wall of the abutting ring 111 after abutting deformation so as to prevent water from entering the bearing box 1; the bearing box 1 is provided with a diversion hole 114 at the bottom of the exposed opening 106; in the working state, the diversion hole 114 can guide and discharge the water splashed to the periphery of the sealing ring 113 and the exposed opening 106.
The sealing ring 113 is made of rubber and has a certain deformation capability. When the movable bearing seat 402 extends out of the supporting brush roll 5 from the exposed opening 106, the sealing ring 113 also moves along with the movable bearing seat, enters the abutting section 112 in the moving process, and when abutting against the inner side wall of the bearing box 1, the bearing seat 401 and the inner side wall of the bearing box 1 extrude the sealing ring 113 to enable the sealing ring to deform and extend along the radial direction, so that the sealing ring abuts against the inner ring wall of the abutting ring 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 1 and is connected to the rear side of the bearing seat 401; the bearing box 1 is internally provided with two parallel guide rods 410 which are spaced from the bottom of the bearing box 1 along the length direction, two ends of each guide rod 410 are respectively connected to the front inner wall and the rear inner wall of the bearing box 1, the bottom of the bearing seat 401 is erected on the guide rods 410 and can axially slide along the guide rods 410, and the bearing seat 401 and the bottom of the bearing box 1 form a vacant area through erection of the guide rods 410.
The drive of hydro-cylinder 409 can be more stable, hydro-cylinder 409 sets up in drive case 115, relatively independent and mutually supporting again with the part in the bearing box 1, the hydro-cylinder 409 piston rod wears to establish and from this can drive to bear seat 401 and remove from the bearing box 1 lateral wall, guide bar 410 provides the point position that bears seat 401 and connect on the one hand, make bear more stable when seat 401 slides, on the other hand also makes and bears seat 401 and movable bearing seat 402 and be in the state of following in the air in bearing box 1 inside, be located the top of bearing box 1 bottom. In actual production, the sealing ring 113 may be aged and broken when used for a long time, which may cause poor sealing effect when the movable bearing seat 402 extends outward, and water may enter the inside of the bearing box 1, but the erected bearing seat 401 and the movable bearing seat 402 may not contact the entering water, and may also play a role in water prevention. The drive box 115 is not affected by water entering through the blocking of the rear side wall of the bearing box 1.
A drainage system is further arranged at the bottom position in the bearing box 1 so as to drain water entering the bearing box 1 when the sealing fails; the drainage system comprises a drainage port 110 arranged at the bottom of the bearing box 1, a plurality of partition plates 107 are vertically arranged on a bottom plate in the bearing box 1, and the partition plates 107 are arranged at intervals along the length direction and the width direction of the bearing box 1 to form a plurality of water collecting sections 108 for preventing water entering the bearing box 1 from spreading; the bottom parts of the partition plates 107 arranged along the length direction of the bearing box 1 are provided with communication holes 109 so as to enable the water collecting sections 108 in the length direction to be communicated with each other; the water introduced into each water collecting compartment 108 can flow from the communication hole 109 to the drain port 110 and be discharged.
The reason for the sealing failure may be that the sealing ring 113 is aged and broken, or fails elastically after being pressed for many times, and cannot return to the original state, so that the sealing failure occurs when the sealing ring is pressed again for sealing. After failure, water enters the bearing box 1, if sealing failure cannot be found in time, more and more water is accumulated in the bearing box 1, and at this time, even if the guide rod 410 is erected, the water finally submerges the positions of the bearing seat 401 and the movable bearing seat 402, so that negative effects are generated.
The water collecting section 108 formed by the partition plate 107 at the bottom of the bearing housing 1 can temporarily collect the entering water, and the water flows into the corresponding water collecting section 108 when flowing from the exposed opening 106 and is discharged from the water discharge opening 110 under the guidance of the communication hole 109. The partition plate 107 can block the spread of the entering water, the water collecting sections 108 in the longitudinal direction of the bearing housing 1 are communicated with each other to guide the water out and prevent the water from accumulating in the bearing housing 1 all the time, and the water not communicated in the width direction of the bearing housing 1 is not communicated to prevent the water entering one water collecting section 108 from spreading to another water collecting section 108, so that the dry environment of other parts can be maintained.
If the partition plate 107 is not provided, when water enters the bearing box 1, the water spreads from the bottom in the bearing box 1 to wet the whole bottom of the bearing box 1, and even if the entering water amount is small, the water still spreads to wet the bottom in the bearing box 1; after the partition plate 107 is arranged, the water entering the bearing box 1 falls into the corresponding water collecting sections 108, and then flows through the water collecting sections 108 communicated in the length direction of the bearing box 1 and is 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 1 or at a position close to the exposed opening 106, so that the water flowing stroke is further shortened, and the drying of other positions of the bottom in the bearing box 1 is ensured; even if the amount of water entering is large, the partition plate 107 can block and divide the water, and the communication hole 109 can guide and drain the water flowing into the corresponding water collection section 108 in time, so that the water does not flow into the water collection sections 108 at other positions, and the relatively dry environment is kept in the bearing box 1 as much as possible.
The bottom of the bearing box 1 is attached to the top surface of the cross beam 2 to prevent water from entering the bearing box 1 from the bottom of the bearing box 1, and a drain pipe for guiding out the water entering the bearing box 1 is arranged at the position, corresponding to the drain port 110, on the cross beam 2.
Because the bottom of the bearing box 1 is attached to the cross beam 2, water splashed in the working state can be effectively prevented from entering the bearing box 1 from the water outlet 110, and if the sealing of the extended movable bearing seat 402 and the exposed opening 106 fails, the entered water can be further led out from the water outlet 110 through the water drain pipe arranged on the cross beam 2, so that the water is prevented from accumulating more and more in the bearing box 1.
Before the preparation of the brush, the upper half part of the rear side of the bearing seat 401 is retracted to form a mounting interval, an encoder 407 is arranged in the mounting interval to enable the bearing box 1 to protect the encoder 407 from water, and the connecting end of the encoder 407 penetrates through the side wall of the bearing seat 401 to be connected with the center of the end part of the rotating core 405, so that the encoder 407 can monitor the running of the brush roller 5 and the driving motor 6 at the same time; this installation interval can prevent bearing seat 401 to bearing box 1 rear side wall when sliding encoder 407 and bearing box 1 rear side wall touch, be connected with the encoder mount pad 408 that is used for bearing encoder 407 on the bearing seat 401 rear side wall.
Usually, the length of the steel plate to be brushed is long, so the brush roller 5 needs to be in a continuous working state, but the situation that the brush roller 5 is separated from the fixed bearing seat 3 or moves the bearing seat 402 occurs in production, at the moment, the brush roller 5 does not brush the steel plate, but whether the brush roller 5 runs or not can not be observed all the time through manual work in the brushing process, and therefore, the encoder 407 is usually arranged to monitor.
In the conventional method, the encoder 407 is mounted on the driving motor 6, and the operating state of the brush roller 5 is derived by monitoring whether the driving motor 6 operates and the number of the rotating speeds, but there is a problem in that if the brush roller 5 is still disengaged at this time, the driving motor 6 will not stop operating and will run idle, but the condition monitored by the encoder 407 is still in a normal operating state; the encoder 407 can detect the abnormal state and signal it only when the driving motor 6 fails and stops operating.
In the embodiment, the encoder 407 is connected to the rotating core 405, and if the brush roller 5 is disengaged, the brush roller 5 is in an inoperative state, the encoder 407 may detect such a situation, and if the brush roller 5 is stopped due to a failure of the driving motor 6, the encoder 407 may detect an abnormal situation, thereby sending a signal. In addition, the encoder 407 is exposed in the conventional manner, but is located inside the bearing housing 1 in this embodiment, which can prevent water and collision. The arrangement of the installation section provides a space required for connecting the encoder 407, and when the bearing seat 401 slides to the rear side, the encoder 407 does not touch the inner side wall of the bearing box 1; on the other hand, the weight of the carriage 401 is also reduced.
The encoder mounting seat 408 is a cylindrical structure and is transversely connected to the rear side of the bearing 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 the connecting end of the encoder mounting seat extends through the rear side wall of the bearing seat 401 in the axial direction of the encoder mounting seat 408 to be connected with the rotary core 405.
Any equipment can be damaged under continuous operation and needs to be repaired and maintained, the arrangement of the access hole is convenient for operators to repair parts inside the bearing box 1, and the coated sealant is used for preventing water splashed in the process of brushing from entering the inside of the bearing box 1 from a gap between the access cover plate 116 and the bearing box 1.
