Description

Technical Field

[0001] This utility model relates to the field of cement pipe edge grinding technology, specifically a cement pipe edge grinding device. Background Technology

[0002] Cement pipes, commonly known as concrete pipes, are cylindrical pipes made by mixing cement as a binder with aggregates (such as sand and stone) and water in a specific ratio, and then processing them through processes such as centrifugal molding, vibration compaction, or roller compaction. Depending on the application, steel bars are often added to enhance tensile strength, forming reinforced concrete pipes. Their main characteristics include high durability, high compressive strength, corrosion resistance, and long service life.

[0003] The "Cement Pipe Production End Grinding Equipment" disclosed in application number "CN221621675U" is also an increasingly mature technology. It includes a grinding box, with a partition fixed near the bottom inside the grinding box. A grinding chamber is located above the partition. A cement pipe inlet is located on one side of the grinding box, leading into the grinding chamber. A flexible rubber sleeve, coaxial with the cement pipe inlet, is fixedly installed on the outer side of the inner end of the grinding box. Guide mechanisms are provided at both the upper and lower ends of the grinding chamber near the cement pipe inlet. A motor is fixedly installed at the end of the grinding chamber opposite to the cement pipe inlet. A fixed plate is fixedly connected to the output end of the motor. A grinding disc is located on one side of the fixed plate. A rod, slidably connected to the fixed plate, is fixed on the other side of the grinding disc. A buffer spring for cushioning the grinding disc is sleeved on the rod. A locking nut is provided on the rod. The grinding disc is coaxial with the cement pipe inlet. Several through holes are opened on the partition. A blower is fixed inside the grinding box. This new invention grinds the end of the cement pipe inside a closed box, making it environmentally friendly and healthy.

[0004] In the existing technology, the grinding of the edge of cement pipes is mostly done manually or with simple mechanical devices, which has the following shortcomings: First, traditional grinding equipment is inconvenient to move and adjust, and it is difficult to accurately control the contact position between the grinding head and the pipe opening, resulting in low grinding efficiency and poor consistency; Second, cement pipes are prone to displacement or vibration during grinding, lack an effective stabilizing mechanism, and cannot achieve automatic rotation of the pipe body and coordinated movement of the grinding head, requiring frequent adjustment of the pipe body posture, which is cumbersome and time-consuming.

[0005] Therefore, it is necessary to provide a cement pipe edge grinding device to solve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a cement pipe edge grinding device, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a cement pipe edge grinding device, comprising a first fixed frame, a movable grinding mechanism provided on the top of the first fixed frame, a second fixed frame provided on one side of the first fixed frame, and a rolling mechanism provided on the top of the second fixed frame.

[0008] Preferably, the movable grinding mechanism includes slide rails fixedly connected to the top two sides of the first fixed frame, a gear rack fixedly connected to one side of one of the slide rails, a movable slide block slidably connected to the top of the slide rail, a first drive motor fixedly connected to one side of the top of the movable slide block, a gear fixedly connected to the transmission end of the first drive motor, the bottom end of the gear meshing with the gear rack, a second drive motor fixedly connected to the top of the movable slide block, a rotating shaft fixedly connected to the transmission end of the second drive motor, and a grinding head fixedly connected to one end of the rotating shaft.

[0009] Preferably, the rolling mechanism includes a third drive motor fixedly connected to the bottom end of the second fixed frame. The transmission end of the third drive motor is fixedly connected to a main gear. Two driven gears are connected to the outer side of the main gear via a chain drive. A drive shaft is fixedly connected to the middle of each driven gear. The two ends of the drive shaft are movably connected to movable drive seats installed at the top ends of the second fixed frame. Several drive rollers are fixedly connected to the outer side of the drive shaft.

[0010] Preferably, two sets of support columns are fixedly connected to the top two sides of the second fixed frame, and an electric telescopic rod is installed at an angle on the top of each support column. The telescopic end of the electric telescopic rod is movably connected to a balance roller.

[0011] Preferably, a switch panel is fixedly connected to one side of the first fixed frame, and a protective layer is provided on the surface of the switch panel.

[0012] Preferably, the surface of the switch panel is fixedly connected with a first drive motor control switch, a second drive motor control switch, a third drive motor control switch, and an electric telescopic rod control switch.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model provides a device for grinding the edge of cement pipes:

[0015] 1. When grinding the edge of the cement pipe, the rotation of the first drive motor drives the gear to rotate, so that the gear meshes with the gear rack during the rotation, causing the movable slide on the slide rail to slide back and forth, making it easier to move the grinding head close to the edge of the cement pipe. During the process, the rotation of the second drive motor drives the rotating shaft to rotate, so that the rotating shaft drives the grinding head to grind the edge of the cement pipe, maintaining the consistency of grinding.

[0016] 2. The rotation of the third drive motor drives the main gear to rotate, which in turn drives the two driven gears at one end of the chain to rotate. This, in turn, drives the two drive shafts to rotate, which in turn drives several drive rollers on the outside. The cement pipe placed on the drive rollers rotates, allowing the grinding head to synchronously grind the edge of the cement pipe, reducing grinding time. To ensure grinding stability, the extension and retraction of electric telescopic rods installed on the top of the two sets of support columns pushes the balance rollers to press and roll the cement pipe, preventing bumps during grinding rotation that could affect the grinding effect on the edge of the cement pipe.

[0028] like Figures 1-4 As shown, the present invention proposes a cement pipe edge grinding device, including a first fixed frame 1, a movable grinding mechanism 2 provided on the top of the first fixed frame 1, a second fixed frame 101 provided on one side of the first fixed frame 1, and a rolling mechanism 3 provided on the top of the second fixed frame 101.

[0029] The movable grinding mechanism 2 includes slide rails 201 fixedly connected to the top two sides of the first fixed frame 1. A gear rack 202 is fixedly connected to one side of one of the slide rails 201. A movable slide block 203 is slidably connected to the top of the slide rails 201. A first drive motor 204 is fixedly connected to one side of the top of the movable slide block 203. A gear 205 is fixedly connected to the transmission end of the first drive motor 204. The bottom end of the gear 205 meshes with the gear rack 202. A second drive motor 206 is fixedly connected to the top of the movable slide block 203. A rotating shaft 207 is fixedly connected to the transmission end of the second drive motor 206. A grinding head 208 is fixedly connected to one end of the rotating shaft 207.

[0030] In practical use, when grinding the edge of the cement pipe, the rotation of the first drive motor 204 drives the gear 205 to rotate, so that the gear 205 meshes with the gear rack 202 during rotation, causing the movable slide block 203 on the slide rail 201 to slide back and forth, making it easier to move the grinding head 208 closer to the edge of the cement pipe. During this process, the rotation of the second drive motor 206 drives the rotating shaft 207 to rotate, so that the rotating shaft 207 drives the grinding head 208 to grind the edge of the cement pipe.

[0031] The rolling mechanism 3 includes a third drive motor 301 fixedly connected to the bottom end of the second fixed frame 101. A main gear 302 is fixedly connected to the transmission end of the third drive motor 301. Two driven gears 303 are connected to the outer side of the main gear 302 via a chain drive. A drive shaft 304 is fixedly connected to the middle of each driven gear 303. The two ends of the drive shaft 304 are movably connected to movable drive seats 305 installed at the top ends of the second fixed frame 101. Several drive rollers 306 are fixedly connected to the outer side of the drive shaft 304.

[0032] In practical use, the rotation of the third drive motor 301 drives the main gear 302 to rotate, which in turn drives the two driven gears 303 at one end of the chain to rotate. This facilitates the rotation of the two drive shafts 304, which in turn drives the several drive rollers 306 on the outside to rotate, so that the cement pipe placed on the drive rollers 306 can rotate, making it easier for the grinding head 208 to grind the edge of the cement pipe.

[0033] Two sets of support columns 4 are fixedly connected to the top two sides of the second fixed frame 101. Each support column 4 is inclinedly installed with an electric telescopic rod 401. The telescopic end of the electric telescopic rod 401 is movably connected with a balance roller 402.

[0034] In practical use, in order to ensure the stability of grinding during the grinding process, the electric telescopic rods 401 installed on the top of the two sets of support columns 4 push the balance rollers 402 to press and roll the cement pipe, preventing bumps during the grinding rotation and affecting the grinding effect of the cement pipe edge.

[0035] A switch panel is fixedly connected to one side of the first fixed frame 1, and a protective layer is provided on the surface of the switch panel.

[0036] The switch panel is fixedly connected to a first drive motor control switch, a second drive motor control switch, a third drive motor control switch, and an electric telescopic rod control switch.
