Description

Technical Field

[0001] The present invention relates to the technical field of bearing seat protection, and in particular to a dustproof protection structure for facilitating the maintenance of a bearing seat. Background Art

[0002] During the use of the bearing seat, in order to ensure the stable operation of the bearing under complex working conditions, extend its service life and improve equipment reliability, a dust protection structure is usually set on the outside of the bearing seat to prevent pollutants from invading the bearing seat and protect the core components of the bearing. The existing dust protection structure usually consists of a fixed base plate and a protective cover body.

[0003] For example: The utility model with application number CN202222953758.X discloses a bearing seat protective cover, which specifically includes a fixed base plate, a bearing seat body and a protective cover body, and the bearing seat body is installed on the upper surface of the fixed base plate; through the cooperation between the fixed base plate, the protective cover body, the oil inlet hole, multiple groups of positioning holes and multiple groups of fixing screws, the multiple groups of positioning holes correspond to the fixing holes on the bearing seat body and are fixed to the frame through multiple groups of fixing bolts, and at the same time, the multiple groups of limit blocks on the lower surface of the protective cover body are embedded in the multiple groups of limit grooves on the upper surface of the fixed base plate through multiple groups of fixing screws, so that they are fixed downward by multiple groups of fixing screws, and the oil inlet hole corresponds to the oil inlet nozzle of the bearing seat body. The protective cover body has high strength and long service life. The oil inlet hole and the oil nozzle are arranged correspondingly to prevent dust from entering, facilitate the addition of lubricating oil to the bearing seat body, and improve the safety of the bearing seat body during operation.

[0004] However, the fixed base plate of the existing bearing seat dust protection structure and the protective cover body are usually fastened together by bolts. When inspecting the bearing seat, the protective cover body fixed by bolts usually requires the staff to unscrew the fixing bolts one by one before removing the protective cover body. The operation process is cumbersome, which increases the labor intensity of the staff and is inconvenient to use. Summary of the Invention

[0005] In view of this, the present invention provides a dustproof protection structure for convenient maintenance of the bearing seat, which has a fixed locking seat that can facilitate the staff to quickly disassemble the protective cover body, align the position of the protective cover body with the fixed base plate, and then place the protective cover body on the fixed base plate. At this time, the control pressure plate will be pressed down under the action of the protective cover body's own weight, and then a series of transmission locking blocks will be reset with the rebound of the connecting spring, so that the locking blocks are inserted into the limit slot to limit the position of the protective cover body. The anti-deviance limit rod can be set to control the disassembly and assembly control slide The frame is limited to prevent the disassembly and assembly control slide from sliding accidentally. When the bearing seat needs to be inspected and repaired, the staff only needs to pull the auxiliary connecting plate to make the auxiliary connecting plate drive the anti-drift limit plug to move and stretch the auxiliary spring. As the anti-drift limit plug moves, the limit on the disassembly and assembly control slide will be released. Then, only the disassembly and assembly control slide needs to be pulled. As the disassembly and assembly control slide moves, the locking card will be driven to move and squeeze the connecting spring. As the locking card moves, the limit on the protective cover body will be released. At this time, the staff can remove the protective cover body for inspection.

[0034] Among them, the outside of the two sets of control racks 110 are meshed with a set of control gears 113; the outside of the fixed base plate 1 is symmetrically hinged to two fixed locking seats 108; the two sets of control gears 113 are coaxially fixedly connected to the rotating shafts at both ends of the fixed locking seats 108.

[0035] Among them, a locking block 114 is slidably connected to each of the two fixed locking seats 108; the inner sides of the two locking blocks 114 are provided with inclined surfaces; the two locking blocks 114 are aligned with the positions of the two limit slots 130 respectively; the outer sides of the two locking blocks 114 are fixedly connected to a group of connecting springs 115; the ends of the two groups of connecting springs 115 are respectively fixedly connected to the two fixed locking seats 108.

[0036] Among them, the top surfaces of the two locking blocks 114 are fixedly connected to a disassembly and assembly control slide 116; the inner sliding connection of the two disassembly and assembly control slides 116 is a group of anti-deviation limit rods 117; the lower parts of the two groups of anti-deviation limit rods 117 are respectively inserted into the top surfaces of the two fixed locking seats 108; the upper parts of the two groups of anti-deviation limit rods 117 are fixedly connected to an auxiliary connecting plate 118; the bottom end surfaces of the two auxiliary connecting plates 118 are fixedly connected to a group of auxiliary springs 119; the ends of the two groups of auxiliary springs 119 are respectively fixedly connected to the top surfaces of the two fixed locking seats 108; the two groups of auxiliary springs 119 are respectively arranged in an alternating shape with the two groups of anti-deviation limit rods 117.

[0038] Specific usage and function of this embodiment: In the present invention, when the protective cover body 101 is installed on the fixed base plate 1 to protect the bearing seat body 102 from dust, it is only necessary to align the position of the protective cover body 101 and the fixed base plate 1, and then place the protective cover body 101 on the fixed base plate 1. At this time, under the action of the self-weight of the protective cover body 101, the control pressure plate 109 will be pressed down, so that the control pressure plate 109 drives the control rack 110 to move, and as the control rack 110 moves, the rack guide slide 111 will be driven to slide in the fixed base plate 1 and stretch the reset spring 112. The sliding of the rack guide slide 111 can provide the movement of the control rack 110. Good guidance, the setting of the anti-slip groove 104 can increase the friction during maintenance by disassembling and assembling. In the process of controlling the movement of the rack 110, the control gear 113 engaged therewith will be driven to rotate, and as the control gear 113 rotates, the fixed locking seat 108 will be driven to flip over, so that the fixed locking seat 108 is stuck on the outside of the protective cover body 101. In the process of flipping the fixed locking seat 108, the protective cover body 101 will squeeze the locking block 114, so that the locking block 114 slides in the fixed locking seat 108, which will squeeze the connecting spring 115. After the fixed locking seat 108 is flipped over, the locking block 114 is just aligned with the position of the limit slot 130. When the cam 114 is in the closed position, the locking block 114 will be reset as the connecting spring 115 rebounds, so that the locking block 114 is inserted into the limit slot 130, limiting the position of the protective cover body 101. The anti-deviating limit rod 117 is set to limit the disassembly and assembly control slide 116 to prevent the disassembly and assembly control slide 116 from sliding accidentally. When the bearing seat needs to be repaired, the staff only needs to pull the auxiliary connecting plate 118 to make the auxiliary connecting plate 118 drive the anti-deviating limit rod 117 to move and stretch the auxiliary spring 119. As the anti-deviating limit rod 117 moves, the limit on the disassembly and assembly control slide 116 will be released, and then the disassembly and assembly control slide 116 can be released by pulling the disassembly and assembly control slide 116. 6. As the disassembly and assembly control slide 116 moves, the locking block 114 will be driven to move and squeeze the connecting spring 115. As the locking block 114 moves, the limit on the protective cover body 101 will be released. At this time, the staff can remove the protective cover body 101 for inspection. By cooperating with the installation limit column 105 and the installation limit groove 106, the protective cover body 101 only needs to be fixed on both sides, reducing the steps of releasing the fixation during inspection. The setting of the damping rubber sealing ring 107 can form a damping buffer layer, enhance the performance of the installation limit column 105 under high vibration conditions, and prevent dust from entering the gap between the installation limit groove 106 and the installation limit column 105.

[0041] Specific usage and function of this embodiment: In the present invention, by setting the temperature-changing metal sheet 123, when the temperature inside the protective cover body 101 is high, the end of the temperature-changing metal sheet 123 connected to the first auxiliary connecting rod 124 will bend, and as the temperature-changing metal sheet 123 is completely bent, the transmission connecting lever 125 will be pulled through the first auxiliary connecting rod 124 to swing. During the swinging process of the transmission connecting lever 125, the heat dissipation control slider 127 will be pulled to slide through the second auxiliary connecting rod 126. During the movement of the heat dissipation control slider 127, the transmission rack 128 will be driven to move, and as the transmission rack 128 moves, it will drive the gear engaged with it. The transmission gear 129 rotates, and as the transmission gear 129 rotates, the heat dissipation hole baffle 122 is driven to rotate, so that the heat dissipation hole baffle 122 is opened to expose the bearing seat heat dissipation holes 120 to dissipate heat to the bearing seat body 102 in the protective cover body 101. At the same time, the setting of the heat dissipation dustproof net 121 can block external dust during the heat dissipation process. When the temperature inside the protective cover body 101 is low, the temperature-changing metal sheet 123 will gradually reset, and then as the temperature-changing metal sheet 123 is reset, the heat dissipation hole baffle 122 will be reset, blocking the bearing seat heat dissipation holes 120 to prevent dust from entering the bearing seat heat dissipation holes 120.
