Description

Technical Field

[0001] This invention relates to a special device for marking and marking lines, and more particularly to a special device for marking and marking lines on the waterproof sleeve of a conduit frame. Background Technology

[0002] In the manufacturing and installation of offshore oil platform jackets, the riser sleeve, as a critical component, requires precise circular markings on its surface to guide subsequent cutting, docking, or installation operations. Currently, common marking methods rely heavily on manual operation. Operators need to climb ladders or scaffolding, use measuring tapes to measure and position, and then draw circles freehand around the pipe wall with a pen or chalk. This method has significant limitations: First, due to the large diameter and long circumference of the riser sleeve, it is difficult to ensure the roundness and flatness of the lines drawn freehand, resulting in poor accuracy and uneven line thickness. Second, manual work at height is inefficient, poses safety hazards, and is highly dependent on the skills and experience of the operators. Furthermore, for situations requiring marking multiple markings at different heights, repeated climbing, measuring, and drawing are time-consuming and laborious, and consistency is difficult to guarantee.

[0003] Therefore, the core technical problem to be solved by this application is: how to provide a special device that can quickly and accurately complete the marking of ring-shaped lines on the outer wall of large pipe fittings, adapt to a certain length range, and be safe and convenient to operate. Summary of the Invention

[0004] The main objective of this invention is to provide a special device for marking and marking the water-proof sleeve of a conductor frame, so as to solve the problems raised in related technologies.

[0005] To achieve the above objectives, according to one aspect of the present invention, a special device for marking and marking water-proof sleeves of conduit supports is provided, comprising a frame, with movable wheels fixedly connected to the four corner edges of the bottom of the frame, and climbing ladders symmetrically fixedly arranged on one side of the frame. A mounting plate is fixedly arranged on the frame, and a lifting cylinder is fixedly arranged at the center of the mounting plate. A power module is also fixedly arranged on the mounting plate. A fixing plate is fixedly connected to one end of the piston rod of the lifting cylinder. A rotating component is slidably arranged on the fixing plate. The rotating component includes at least a meshing pinion and a large gear, and a marking pen is slidably arranged inside the large gear. A limit component is also fixedly arranged on the fixing plate, and guide components are fixedly arranged at both ends of the frame.

[0006] Furthermore, the guide component includes a fixed cylinder fixedly mounted on the frame, a sliding rod slidably mounted on the upper end of the fixed cylinder, and the upper end of the sliding rod is fixedly mounted on the bottom of the fixed plate.

[0007] Furthermore, guide rails are symmetrically fixed on the fixed plate, and support plates are slidably mounted on the two guide rails.

[0008] Furthermore, several positioning holes are provided on both sides of the guide rail and the support plate, and positioning pins are installed in the internal threads of the positioning holes on the support plate.

[0009] Furthermore, the rotating component also includes upright plates symmetrically fixedly mounted on the support plate, the pinion gear is rotatably mounted between the two upright plates, and a motor is fixedly mounted on the support plate, the output shaft of the motor being fixedly connected to the rotation shaft of the pinion gear.

[0010] Furthermore, the limiting component includes support rods fixedly disposed at both ends of the fixed plate, with fixed rings fixedly connected to the support rods, and several connecting rods fixedly connected in a circular array between the two fixed rings.

[0011] Furthermore, the large gear is ring-shaped, and the outer wall of the connecting rod is in close contact with the inner wall of the large gear.

[0012] Furthermore, the large gear has a slot, the drawing pen is slidably disposed in the slot, and the outer wall of the drawing pen is symmetrically and fixedly connected with a limiting plate.

[0013] Furthermore, the large gear has sliding grooves on both sides of the slot that communicate with it, and the limiting plate is slidably disposed in the sliding grooves.

[0014] Furthermore, a spring is fixedly installed inside the slide groove, with one end of the spring fixedly connected to the inner wall of the slide groove and the other end fixedly connected to the side wall of the limiting plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This specialized device for marking and marking water-resistant sleeves of conductor supports utilizes a motor-driven gear set to rotate a large gear equipped with a marking pen. This allows the marking pen to perform precise circular motions around the water-resistant sleeve, which is centered and supported by limiting components, thus drawing neat circular marking lines on the sleeve wall. This method completely eliminates problems such as poor roundness and uneven joints that occur with manual marking, resulting in high-quality and consistent markings. Automated operation significantly improves marking efficiency, reduces reliance on operator skills, minimizes time spent working at heights, and enhances safety.

[0016] 2. This device, used for marking and marking water-resistant sleeves on conduit supports, incorporates a support plate that allows the marking assembly to slide along a guide rail. This enables flexible adjustment of the radial position of the marking pen relative to the pipe axis, accommodating water-resistant sleeves of varying diameters. Simultaneously, the marking pen is slidably mounted on a large gear via a spring mechanism. When it rotates to meet the connecting rod of the limiting component, the pen retracts under pressure, and after overcoming the obstacle, returns to its original position under spring action, contacting the pipe wall and naturally forming a discontinuous marking line. This discontinuous line is more easily identifiable than a continuous coil in certain applications, and this function requires no additional control, demonstrating ingenious structure and strong practicality.

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0020] This embodiment provides a special device for marking and drawing lines on the water-proof sleeve of a guide frame. Its main function is to quickly and accurately draw a ring-shaped marking line on the outer cylindrical surface of a large water-proof sleeve. The device includes a frame 1, which is welded from steel profiles and has sufficient structural strength and stability. To facilitate movement, the four corner edges of the bottom of the frame 1 are fixedly connected with casters 11. These casters 11 are preferably universal casters with brakes. In order to facilitate operators to go up and down the frame 1 to make necessary adjustments or observations, climbing ladders 13 are symmetrically fixed on one side of the frame 1. A mounting plate 12 is fixedly installed on the frame 1. A lifting cylinder 3 is fixedly installed at the center of the mounting plate 12. A power module 2 is also fixedly installed on the mounting plate 12. The power module 2 can be a battery or a transformer and rectifier connected to an external power source, used to supply power to the electrical components on the device. The piston rod of the lifting cylinder 3 extends vertically upward. A fixing plate 4 is fixedly connected to one end of the piston rod of the lifting cylinder 3. A rotating component 6 is slidably installed on the fixing plate 4. The rotating component 6 includes at least a meshing pinion 62 and a large gear 63. A drawing pen 9 is slidably installed inside the large gear 63. A limit component 7 is also fixedly installed on the fixing plate 4. Guide components 8 are also fixedly installed at both ends of the frame 1.

[0021] like Figure 1 and Figure 2 As shown, the guide component 8 includes a fixed cylinder 81 fixedly mounted on the frame 1. A sliding rod 82 is slidably mounted on the upper end of the fixed cylinder 81, and the upper end of the sliding rod 82 is fixedly mounted on the bottom of the fixed plate 4. Therefore, when the piston rod of the lifting cylinder 3 extends and retracts, driving the fixed plate 4 to move longitudinally, the sliding rod 82 slides inside the fixed cylinder 81, playing a guiding and stabilizing role, effectively preventing the fixed plate 4 from tilting due to uneven force.

[0022] like Figure 2 and Figure 3 As shown, guide rails 41 are symmetrically fixed on the fixed plate 4, and support plates 5 are slidably mounted on the two guide rails 41. The support plates 5 slide with the two guide rails 41 through the slider at their bottom, so that the support plates 5 can move in a direction parallel to the length of the fixed plate 4. In order to fix the support plates 5 in the required position, several positioning holes are opened on both sides of the guide rails 41 and the support plates 5. Positioning pins 51 are installed in the internal threads of the positioning holes on the support plates 5. When the support plates 5 slide to the predetermined position, the positioning pins 51 can be inserted into the aligned positioning holes and tightened to achieve locking.

[0023] like Figure 2 and Figure 3 As shown, the rotating component 6 also includes upright plates 61 symmetrically fixed on the support plate 5. The small gear 62 is rotatably mounted between the two upright plates 61 via a rotating shaft and bearings. A motor 52 is fixedly mounted on the support plate 5, and the output shaft of the motor 52 is fixedly connected to the rotating shaft of the small gear 62. Therefore, when the small gear 62 is driven to rotate by the motor 52, it can drive the large gear 63 to rotate around its own axis. The power module 2 is electrically connected to the lifting cylinder 3 and the motor 52 via wires.

[0024] like Figure 1 and Figure 2 As shown, the limiting component 7 includes support rods 72 fixedly disposed at both ends of the fixed plate 4. A fixing ring 71 is fixedly connected to the support rod 72, and several connecting rods 73 are fixedly connected in a ring array between the two fixing rings 71.

[0025] like Figure 2 and Figure 3 As shown, the large gear 63 is ring-shaped, and the outer wall of the connecting rod 73 is in close contact with the inner wall of the large gear 63, which can further enhance the stability of the rotating component 6. The large gear 63 can rotate under the rotation of the small gear 62. When using the device, the frame 1 is moved to one end of the water-proof sleeve by the moving wheel 11, and the fixed plate 4 is moved by the lifting cylinder 3 until the water-proof sleeve is aligned with the fixed ring 71. Then, the frame 1 is moved by the moving wheel 11 to insert the water-proof sleeve into the fixed ring 71, and the outer wall of the water-proof sleeve is in close contact with the side wall of the connecting rod 73. According to the drawing position requirements, the support plate 5 is slid along the guide rail 41 to drive the rotating component 6 to slide, so that the drawing pen 9 reaches the designated position on the outer wall of the water-proof sleeve.

[0026] like Figure 4 and Figure 5 As shown, the large gear 63 has a slot 631, the drawing pen 9 is slidably disposed in the slot 631, and the outer wall of the drawing pen 9 is symmetrically fixedly connected to a limiting plate 91.

[0027] like Figure 4 and Figure 5As shown, the large gear 63 has grooves 632 communicating with it on both sides of the slot 631. The limiting plate 91 is slidably disposed in the groove 632, and a spring 633 is fixedly disposed in the groove 632. One end of the spring 633 is fixedly connected to the inner wall of the groove 632, and the other end is fixedly connected to the side wall of the limiting plate 91. Therefore, when the small gear 62 is driven to rotate by the motor 52, the large gear 63 rotates accordingly, and the drawing pen 9 moves outward from the water-proof sleeve. The wall achieves circular motion to perform the line drawing operation. When the drawing pen 9 rotates to meet a certain connecting rod 73, the connecting rod 73 will block the path of the drawing pen 9. The drawing pen 9 is pushed to compress the spring 633 and slides inward along the slot 631 until the drawing pen 9 passes the connecting rod 73. Under the restoring force of the spring 633, it resets along the slot 631, so that the drawing end of the drawing pen 9 contacts the surface of the waterproof sleeve, thereby drawing intermittent ring marks on the outer wall of the waterproof sleeve.

[0028] In practical use, the frame 1 is moved to one end of the waterproof sleeve by the moving wheels 11. The lifting cylinder 3 is activated to move the fixing plate 4 until the waterproof sleeve is aligned with the fixing ring 71. The moving wheels 11 continue to move the frame 1, pushing the frame 1 so that the waterproof sleeve passes through the fixing ring 71 and the outer wall of the waterproof sleeve is in close contact with the side wall of the connecting rod 73. According to the drawing position requirements, the support plate 5 slides along the guide rail 41, driving the rotating component 6 to slide, so that the drawing pen 9 reaches the waterproof sleeve. The support plate 5 is fixed at a designated position on the outer wall using positioning pins 51; the motor 52 is started to drive the small gear 62 to rotate, which in turn drives the large gear 63 to rotate, and the drawing pen 9 then makes a circular motion on the outer wall of the waterproof sleeve to draw lines; when the drawing pen 9 passes the connecting rod 73, it is pushed and compressed by the spring 633 and slides inward along the slot 631. After passing the connecting rod 73, it is reset by the restoring force of the spring 633, so that the drawing end contacts the surface of the waterproof sleeve and draws intermittent circular marks on the outer wall of the waterproof sleeve.
