Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment protection technology, and in particular to a waterproof cover that is easy to install. Background Technology

[0002] A waterproof cover is a protective covering used to block water and prevent water from entering equipment, items, or specific areas.

[0003] Under current conditions, a waterproof cover for a rotary kiln bearing assembly, as disclosed in CN216715010U, is commonly used. This cover includes a housing, with hinged doors on both sides of the hollow housing. Each door has a handle for opening. This effectively protects the drive mechanism and the rotary kiln bearing assembly from rainwater corrosion, and the housing is detachable. However, this waterproof cover uses a locking mechanism to fix the housing to itself. The elastic locking structure has poor stability and is prone to detachment during equipment vibration or external force, failing to guarantee long-term reliable fixation and indirectly affecting the waterproofing effect. Furthermore, rainwater lacks a clear flow path on the housing surface, easily flowing along the housing wall towards the bearing assembly. This not only allows water to penetrate critical components but also splashes, expanding the corrosion range and shortening the equipment's lifespan. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the existing waterproof cover for roller bearing assembly has poor rainwater diversion effect, which easily leads to bearing corrosion, and to propose a waterproof cover that is easy to install.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An easy-to-install waterproof cover includes a base mounted on a ball mill, a bearing housing fixedly mounted on the base, a ball bearing corresponding to the bearing housing mounted on the ball mill, a support frame fixedly mounted on the base, and a support rod slidably mounted on the support frame. A fixing bolt for fixing the position of the support rod is threaded onto the support frame. A cover for providing waterproof protection to the ball bearing of the ball mill is fixedly mounted between the two support rods. The cover is composed of a first half-cover and a second half-cover, and a connecting mechanism connects the first half-cover and the second half-cover to drive them to close and form a hollow cylindrical structure to cover the connection end of the bearing housing and the ball bearing.

[0006] Preferably, a positioning block extending into the second half of the cover is fixedly installed on the first half of the cover, a waterproof plate for preventing water leakage at the joint is fixedly installed on the first half of the cover, and the waterproof plate has an arc plate structure. The second half of the cover is provided with an arc-shaped inclined groove corresponding to the waterproof plate.

[0007] Preferably, water-blocking plates for guiding rainwater are fixedly installed on both sides of the first and second half-covers, and side baffles for preventing rainwater from seeping in from the sides of the water-blocking plates are fixedly installed on the waterproof plates. Drainage racks that cooperate with the water-blocking plates and collect rainwater are fixedly installed on the first and second half-covers, and water guide pipes for preventing rainwater from splashing are fixedly installed at the lower end of the drainage racks.

[0008] Preferably, the drainage frame has a V-shaped structure that is wider at the top and narrower at the bottom, and the base has a drainage hole corresponding to the water guide pipe.

[0009] Preferably, the connecting mechanism includes a connecting frame with a pin mounted on the first half-cover, a fixing block corresponding to the connecting frame fixedly mounted on the second half-cover, and bolts for fixing the connecting frame threaded onto the fixing block.

[0010] Preferably, the connecting frame is located in the middle of the half-cover, the connecting frame is an L-shaped structure, and a waterproof frame for preventing rainwater from eroding the bolts is fixedly installed on the upper end of the connecting frame, and the waterproof frame is an inverted V-shaped structure that is narrower at the top and wider at the bottom.

[0011] Compared with the prior art, the present invention has the following advantages: 1. This utility model can complete the closure and initial fixation of the cover through simple linear pushing and tightening actions, and then lock it with the support frame. The whole process does not require complicated tools or cumbersome adjustments, which helps to improve installation efficiency. At the same time, the precise insertion of the positioning block and the reliable limiting of the connecting frame ensure the concentricity of the half cover closure and the overall structural stability, effectively avoiding installation misalignment and helping to improve the reliability of installation and the consistency of waterproof sealing.

[0012] 2. This utility model achieves effective management of rainwater through multiple guiding and centralized diversion. The waterproof frame diverts rainwater from key connection parts, the baffle guides rainwater to flow directionally along the surface of the cover, and the diversion frame and water pipe work together to collect and directionally discharge rainwater. This not only effectively prevents rainwater from corroding bearings and connecting parts, but also avoids secondary leakage caused by rainwater splashing, which helps to improve the sealing reliability of the waterproof cover and the long-term protection capability of core components.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-5 An easy-to-install waterproof cover includes a base 1 mounted on a ball mill, a bearing seat 2 fixedly mounted on the base 1, a ball bearing 3 corresponding to the bearing seat 2 mounted on the ball mill, the ball bearing 3 being embedded in the bearing seat 2 to achieve low-friction transmission when the ball mill rotates, a support frame 4 fixedly mounted on the base 1, and a support rod 5 slidably mounted on the support frame 4, a fixing bolt for fixing the position of the support rod 5 being threadedly connected to the support frame 4, the screw end of the fixing bolt extending to the inner wall of the support frame 4, and locking and fixing the support rod 5 by tightening the bolt against the outer wall of the support rod 5.

[0017] A cover is fixedly installed between the two support rods 5 to provide waterproof protection for the ball mill ball bearing 3. The cover is made of corrosion-resistant engineering plastic and is integrally injection molded. It is lightweight, wear-resistant and waterproof. The cover is composed of half cover one 6 and half cover two 7.

[0018] A connecting mechanism is provided between half-cover 6 and half-cover 7 to drive them to close and form a hollow cylindrical structure to cover the connection end of the bearing housing 2 and the ball bearing 3. The connecting mechanism enables the half-cover to be quickly positioned and locked, ensuring the sealing performance of the joint after closure, thereby effectively covering the connection end of the bearing housing 2 and the ball bearing 3 and blocking the intrusion path of external substances such as rainwater and dust.

[0019] A positioning block 8 extending into the second half of the cover 7 is fixedly installed on the first half of the cover 6. The second half of the cover 7 has a positioning groove corresponding to the positioning block 8. The positioning groove cooperates with the positioning block 8. The positioning block 8 is made of the same corrosion-resistant engineering plastic material as the first half of the cover 6, so as to achieve precise positioning when the first half of the cover 6 and the second half of the cover 7 are closed, and avoid gaps at the joint due to misalignment.

[0020] A waterproof membrane 9 is fixedly installed on the half-cover 6 to prevent water leakage at the joint. The waterproof membrane 9 is made of elastic rubber and has good sealing and aging resistance. The waterproof membrane 9 can completely cover the joint between the half-cover 6 and the second half-cover 7, effectively preventing rainwater from seeping in from the half-cover 6 and the second half-cover 7.

[0021] The waterproof membrane 9 has an arc-shaped structure. The second half of the cover 7 has an arc-shaped groove corresponding to the waterproof membrane 9. The depth of the arc-shaped groove is matched with the thickness of the waterproof membrane 9. When the first half of the cover 6 and the second half of the cover 7 are closed, the waterproof membrane 9 can be perfectly embedded in the arc-shaped groove to form a labyrinth-like sealing structure, which effectively prevents rainwater from seeping in from the joint and further improves the overall waterproof performance of the waterproof cover.

[0022] Water baffles 11 for guiding rainwater are fixedly installed on both sides of half cover 6 and half cover 7. The two sets of water baffles 11 correspond to the two sides of half cover 6 and half cover 7 respectively. When the half cover is closed, the water baffles 11 on both sides form symmetrical rainwater guiding channels, which limit the rainwater on the surface of the half cover to a specific flow range and prevent rainwater from flowing randomly to the ball bearing 3 area.

[0023] Side baffles 10 are fixedly installed on the waterproof membrane 9 to prevent rainwater from seeping in from the side of the baffle 11. When the first half cover 6 and the second half cover 7 are closed, the side baffles 10 fit tightly against the inner walls of the baffles 11 on both sides of the second half cover 7, forming a surrounding sealed barrier, effectively preventing rainwater from seeping in from the joint between the baffle 11 and the waterproof membrane 9, and completely cutting off the side path of rainwater seeping into the bearing area.

[0024] Half-cover 6 and half-cover 7 are fixedly installed with a diversion frame 12 that cooperates with the baffle plate 11 and collects rainwater. The overall structure of the diversion frame 12 covers the end of the guide channel formed by the baffle plate 11, which can accurately receive the rainwater flowing down from the baffle plate 11 and collect the dispersed rainwater to the central area.

[0025] A water guide pipe 13 is fixedly installed at the lower end of the drainage frame 12 to prevent rainwater from splashing. The water guide pipe 13 is made of PVC material and extends to 1-2 cm above the drain hole of the base 1. This ensures that the rainwater collected by the drainage frame 12 can be vertically guided into the drain hole of the base through the water guide pipe 13, avoiding splashing of rainwater during the fall and thus preventing rainwater from contacting the connection between the bearing seat 2 and the ball bearing 3 for the second time.

[0026] The diversion frame 12 has a V-shaped structure that is wider at the top and narrower at the bottom. The width of the upper edge of the V-shaped opening is matched with the width of the guide channel formed by the baffle plate 11, ensuring that the rainwater flowing down from the baffle plate 11 can fall smoothly into the diversion frame 12 and avoid rainwater overflow. The base 1 has a drainage hole corresponding to the water guide pipe 13.

[0027] The connecting mechanism includes a connecting frame 14 with a pin mounted on half cover 6, and a fixing block 15 corresponding to the connecting frame 14 is fixedly mounted on half cover 7, and bolts for fixing the connecting frame 14 are threaded onto the fixing block 15.

[0028] The connecting frame 14 is located in the middle of half-cover 6. The position of the connecting frame 14 coincides with the docking center line of half-cover 6 and half-cover 7, ensuring that the fixing force of the connecting frame 14 on the two half-covers can be evenly transmitted to the whole cover, avoiding local gaps after the half-covers are closed due to uneven force, and further improving the sealing performance and structural stability of the cover closure.

[0029] The connecting frame 14 has an L-shaped structure. A waterproof frame 16 is fixedly installed on the upper end of the connecting frame 14 to prevent rainwater from eroding the bolts. The waterproof frame 16 has an inverted V-shaped structure that is narrow at the top and wide at the bottom. When rainwater falls on the waterproof frame 16, the inverted V-shaped slope can quickly guide the rainwater to both sides, so that the rainwater flows down along the outside of the connecting frame 14 and completely avoids the bolt area on the fixing block 15.

[0030] The functional principle of this utility model can be explained through the following operation methods: Push the two support rods 5 to move towards the middle of the base 1. The two support rods 5 respectively drive the first half cover 6 and the second half cover 7 to move towards the middle and merge. The positioning block 8 extends into the second half cover 7 at the same time. Rotate the connecting frame 14 so that one end of the L-shaped connecting frame 14 limits the fixing block 15. Tighten the bolts on the fixing block 15 to achieve the initial fixation of half cover 6 and half cover 7. Then tighten the fixing bolts on the support frame 4 to complete the rapid installation of the waterproof cover. When rainwater falls on the waterproof cover, the waterproof frame 16 guides the rainwater to both sides of the connecting frame 14 to prevent rainwater from corroding the bolts at the connecting structure. At the same time, the baffle plate 11 guides the rainwater, so that the rainwater flows along the surfaces of half cover 6 and half cover 7 respectively, and the side baffle plate 10 prevents the rainwater from seeping in from the side of the baffle plate 11 and avoids the rainwater from flowing to the ball bearing 3. The drainage frame 12 guides and collects the flowing rainwater. Because the drainage frame 12 has a V-shaped structure that is wider at the top and narrower at the bottom, the rainwater is discharged through the water pipe 13 after being collected, and finally discharged through the drainage hole on the base 1, preventing rainwater from splashing and corroding key components.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
