Description

Technical Field

[0001] This utility model relates to the field of pipe manufacturing, and more specifically, to a grinding and rust removal device for pipe sockets. Background Technology

[0002] In modern industry and infrastructure construction, pipeline systems are widely used. Whether in the transportation of oil and natural gas or in urban water supply and drainage projects, pipelines play an indispensable role. Pipeline connections mostly use socket joints, which offer good sealing and convenient installation. In actual production, refer to the attached... Figure 5 and Figure 6 As shown, the pipe body 13 has a socket end 14 and a spigot end 15. After the pipe is formed, there will be concrete scum and rust at the socket and spigot. The generation of rust will not only affect the sealing of the pipe connection, causing media leakage, safety hazards and resource waste, but also reduce the service life of the pipe and increase maintenance costs. Therefore, it is necessary to manually grind the concrete scum and remove rust at the socket and spigot using a grinding device. After the pipe is ground, it needs to be hoisted onto the platform of the pipe turning machine by a crane. Then, the pipe is turned from vertical to horizontal by the pipe turning machine and then poured into the finished product area for anti-corrosion operation.

[0003] However, the common methods for rust removal of pipe sockets currently include manual grinding and some simple mechanical rust removal tools. Manual grinding is inefficient, labor-intensive, and the rust removal effect largely depends on the worker's experience and skill level, making it difficult to guarantee the uniformity and thoroughness of rust removal. On the other hand, some existing simple mechanical rust removal tools often have the problems of limited functionality and poor adaptability, and cannot perform efficient and precise grinding and rust removal operations for pipe sockets of different diameters.

[0004] To address the above problems, this utility model proposes a grinding and rust removal device for pipe sockets. Utility Model Content

[0005] The present invention aims to solve the technical problems mentioned in the background art and provide a grinding and rust removal device for pipe sockets.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grinding and rust removal device for pipe sockets, comprising: a mounting bracket, which is fixedly mounted on a work platform; a rotating plate is rotatably connected to the top of the mounting bracket via a rotating shaft; and a driving component for driving the rotating shaft to rotate is provided on the mounting bracket.

[0007] Two sets of first telescopic mechanisms are fixedly installed on both sides of the rotating plate. At the end of each set of first telescopic mechanisms away from the rotating plate, a grinding device is fixedly installed that can contact the end face of the pipe socket to be ground and rusted.

[0008] A further preferred embodiment: the drive assembly includes a motor, a first gear and a second gear, the motor is fixedly mounted on the mounting bracket, the first gear is sleeved and fixedly mounted on the drive end of the motor, the second gear is sleeved and fixedly mounted on the rotating shaft, and the second gear meshes with the first gear.

[0009] A further preferred embodiment: the diameter of the second gear is larger than the diameter of the first gear.

[0010] A further preferred embodiment: the mounting bracket includes a top plate, a bottom plate, and multiple support rods, the multiple support rods are fixedly installed between the bottom plate and the top plate, the motor is fixedly installed on the bottom plate, and the rotating shaft is rotatably mounted on the top plate.

[0013] A further preferred embodiment: a fixing plate for fixing the grinding equipment is fixedly installed on the fixing frame, and a wire through hole is provided through the mounting frame.

[0014] A further preferred embodiment: two movable plates are fixedly connected to the fixed frame, the two movable plates are movably disposed within the mounting frame, the mounting frame is provided with movable slots for the movable plates to move, and multiple reinforcing plates are fixedly connected at intervals on the rotating plate.

[0015] Beneficial effects:

[0016] 1. By setting up a first telescopic mechanism, a drive component, and a rotating plate, the grinding equipment is driven to rotate by the drive component, and the position of the grinding equipment is adjusted by the first telescopic mechanism. This allows for grinding and rust removal operations to be performed when the pipeline is hoisted on the work platform, eliminating the need for manual grinding of the pipeline sockets. This saves labor costs and time, improves the efficiency of grinding and rust removal of pipeline sockets, and enables grinding and rust removal operations on pipeline sockets of different diameters, thereby improving the versatility of the device.

[0025] The following will refer to the appendix in the embodiments of this utility model. Figures 1-6 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0026] Please see Figure 1-4In this embodiment of the utility model, a grinding and rust removal device for pipe sockets includes a mounting bracket 3, which is fixedly installed on a work platform. A rotating plate 1 is rotatably connected to the top of the mounting bracket 3 via a rotating shaft 11. A driving component 9 for driving the rotating shaft 11 to rotate is provided on the mounting bracket 3. Two sets of first telescopic mechanisms 4 are fixedly installed on both sides of the rotating plate 1. A grinding device 10 is fixedly installed at the end of each set of first telescopic mechanisms 4 away from the rotating plate 1, which can contact the end face of the pipe socket to be ground and rust removed.

[0027] Specifically, in this embodiment, the work platform is initially set as a pipe turning machine. The rotating shaft 11 is coaxially arranged with the pipe on the work platform placement platform. After the pipe to be ground and rusted is hoisted onto the work platform placement platform by a crane, the pipe is vertically stationary on the work platform placement platform. Then, according to the pipe diameter, the position of the grinding equipment 10 is adjusted by the first telescopic mechanism 4 so that the grinding wheel of the grinding equipment 10 contacts the end face of the pipe to be ground. Then, the grinding equipment 10 is started, and at the same time, the rotating shaft 11 is driven to rotate by the drive component 9, thereby causing the rotating plate 1 to rotate around the rotating shaft 11. The rotating plate 1 drives the grinding equipment... The equipment 10 rotates, allowing it to grind and remove rust from the socket end of the pipe. After grinding and rust removal, the work platform flips the pipe vertically to horizontally, adjusting its direction and facilitating its movement to the finished product for corrosion protection. The overall structure is simple to operate, enabling grinding and rust removal while the pipe is hoisted on the work platform. This eliminates the need for manual grinding of the socket end, saving labor costs and time and improving the efficiency of grinding and rust removal on the pipe socket end. Furthermore, it can grind and remove rust from the socket ends of pipes of different diameters, thus enhancing the versatility of the device.

[0028] It should be noted that the structure of the work platform in this embodiment is existing technology and will not be described here. The work platform is equipped with this device at both the top and bottom of its placement platform. That is, the top and bottom of the work platform are fixedly installed with mounting brackets 3 relative to the pipes on its placement platform. Each mounting bracket 3 is equipped with a rotating plate 1, a first telescopic mechanism 4, and a grinding device 10. Thus, when the pipe is vertical on the work platform, the two sets of this device are used to grind and remove rust from the socket end and the spigot end of the pipe body, respectively. That is, the outer wall of the socket end and the inner wall of the spigot end are ground and removed from rust. Of course, in specific implementation, the position of the grinding device 10 can be adjusted according to the actual situation (provided that this device will not affect the work platform when the pipe is flipped). This is existing technology. Furthermore, in this embodiment, the grinding device 10 is preferably an electric angle grinder. Of course, other grinding machines can also be used. The specific choice can be made according to the actual situation and is not limited here. Secondly, the first telescopic mechanism 4 is preferably an electric telescopic rod. Of course, in other embodiments, it can also be a hydraulic telescopic rod, etc. In other embodiments, the work platform can be selected according to the actual situation and is not limited here.

[0029] In this embodiment of the utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, the drive assembly 9 includes a motor 93, a first gear 91, and a second gear 92. The motor 93 is fixedly mounted on the mounting bracket 3. The first gear 91 is sleeved and fixedly mounted on the drive end of the motor 93. The second gear 92 is sleeved and fixedly mounted on the rotating shaft 11. The second gear 92 meshes with the first gear 91. Specifically, by starting the motor 93, the first gear 91 is driven to rotate. Since the first gear 91 meshes with the second gear 92, the second gear 92 rotates accordingly, thereby driving the rotating shaft 11 to rotate, which in turn drives the rotating plate 1 and the grinding equipment 10 to rotate. The gear meshing transmission has a simple structure, stable and reliable transmission, and can accurately transmit the power of the motor 93 to the rotating shaft 11, ensuring the stable rotation of the rotating plate 1. Furthermore, the diameter of the second gear 92 is larger than the diameter of the first gear 91. This has the advantage that by reducing the speed, the rotating plate 1 can rotate more smoothly, and the increased torque allows the rotating plate 1 to drive the grinding equipment 10 to overcome greater resistance and rotate, improving the stability and reliability of the device during grinding and rust removal.

[0030] In this embodiment of the utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the mounting bracket 3 includes a top plate 33, a bottom plate 31, and multiple support rods 32. The multiple support rods 32 are fixedly installed between the bottom plate 31 and the top plate 33. The motor 93 is fixedly installed on the bottom plate 31, and the rotating shaft 11 is rotatably mounted on the top plate 33. Specifically, this structural design is simple and stable, providing a reliable installation foundation for all components of the entire device, ensuring the stability of each component during operation, and facilitating installation and maintenance. Furthermore, multiple mounting plates 2 are fixedly installed on both sides of the bottom plate 31. The mounting plates 2 are used to fix the bottom plate 31 to the working platform, and are connected and fixed to the corresponding installation parts on the working platform by bolts and other connecting parts passing through the mounting holes on the mounting plates 2.

[0031] In this embodiment of the utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, connecting plates 6 are fixedly installed at the telescopic ends of both sets of first telescopic mechanisms 4. Mounting frames 7 are fixedly installed on the connecting plates 6. Second telescopic mechanisms 18 are fixedly installed inside the mounting frames 7. Mounting brackets 19 are fixedly installed at the telescopic ends of the second telescopic mechanisms 18. Grinding equipment 10 is fixedly installed on the mounting brackets 19. Mounting plates 8 for fixing the grinding equipment 10 are fixedly installed on the mounting brackets 19. A through-hole 12 is provided on the mounting frame 7. Specifically, the arrangement of connecting plates 6 and mounting frames 7 facilitates the installation and disassembly of the grinding equipment 10. Simultaneously, the first telescopic mechanism 4 pushes... During the movement of the grinding equipment 10, the smooth movement of the grinding equipment 10 can be better guaranteed, thus improving the grinding effect. The fixed plate 8 ensures that the grinding equipment 10 is firmly installed, ensuring the stability and safety of the grinding work. The cable hole 12 makes the cable arrangement neater, avoiding problems such as cable tangling, and improving the reliability of the equipment operation. Secondly, the setting of the second telescopic mechanism 18 allows the device to effectively grind according to the depth and height of the pipe socket, thereby further improving the applicability of the device. It should be noted that the structure of the second telescopic mechanism 18 can refer to the structure of the first telescopic mechanism 4.

[0032] In this embodiment of the utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, two movable plates 16 are fixedly connected to the fixed frame 19. The two movable plates 16 are movably arranged within the mounting frame 7. The mounting frame 7 is provided with movable slots 17 for the movable plates 16 to move. Multiple reinforcing plates 5 are fixedly connected at intervals on the rotating plate 1. Specifically, the reinforcing plates 5 increase the structural strength of the rotating plate 1, improve the strength and stability of the rotating plate 1, extend the service life of the rotating plate 1, ensure the reliability of the entire device during long-term operation, and ensure the continuous and stable operation of grinding and rust removal. Secondly, the arrangement of the movable plates 16 and movable slots 17 helps to improve the stability of movement between the fixed frame 19 and the mounting frame 7, so as to ensure the normal operation of the device.

[0033] Working principle: Initially, two sets of this device are installed on the work platform. After the pipe to be ground and rusted is hoisted onto the placement platform of the work platform by a crane, the pipe is vertically stationary on the placement platform. The two sets of devices are positioned opposite the pipe, corresponding to the socket end and spigot end of the pipe respectively. Then, according to the pipe diameter, the position of the grinding device 10 is adjusted by the first telescopic mechanism 4 and the second telescopic mechanism 18 so that the grinding wheel of the grinding device 10 contacts the end face of the pipe to be ground. That is, the grinding devices 10 of the two sets of devices contact the socket end and spigot end of the pipe respectively. Then, the grinding device 10 is started, and the motor 93 is started to drive the first gear 91 to rotate. Since the first gear 91 and the second gear 92... The second gear 92 rotates due to the meshing, which in turn drives the rotating shaft 11 to rotate, thereby causing the rotating plate 1 and the grinding equipment 10 to rotate. This allows the grinding equipment 10 to perform grinding and rust removal on the socket end of the pipe. After grinding and rust removal are completed, the working platform flips the pipe vertically to horizontally, adjusting the pipe's direction and facilitating its movement to the finished product for anti-corrosion work. The overall structure is simple to operate and can perform grinding and rust removal on the pipe while it is hoisted on the working platform. It eliminates the need for manual grinding of the socket end of the pipe, saving labor costs and time and improving the efficiency of grinding and rust removal on the pipe socket end. At the same time, it can perform grinding and rust removal on the socket ends of pipes of different diameters, thereby improving the versatility of the device.
