Description

Technical Field

[0001] This utility model relates to the technical field of fiberglass rope winding equipment, specifically a high-temperature resistant positioning device for fiberglass rope winding. Background Technology

[0002] Fiberglass rope (hereinafter referred to as "fiberglass rope") is widely used in industrial applications where pipes, mandrels, or irregularly shaped structural components need to be reinforced or sealed due to its excellent high strength, high temperature resistance, insulation, and corrosion resistance. Especially in aerospace, military, and high-temperature chemical industries, it is often necessary to tightly and uniformly wind fiberglass rope at a specific angle (winding angle) onto the surface of workpieces exposed to high-temperature environments (200°C to 600°C or even higher) to form a robust heat-resistant, wear-resistant, or sealing barrier.

[0003] In existing technologies, when winding fiberglass rope, the excessively heavy mandrel is not only laborious and inefficient, but also poses safety hazards (impact injuries, twisting injuries) and risks of equipment or product damage (the mandrel falling and injuring the equipment or drum). It also requires manual lifting and centering, or the use of an external hydraulic lifting platform to lift the mandrel. However, the hydraulic lifting platform is inconvenient to use in spaces with limited space or compact equipment layouts (such as narrow passages, small gaps between equipment, uneven ground, pipeline obstacles, etc.). Utility Model Content

[0004] The purpose of this invention is to provide a high-temperature resistant positioning device for winding fiberglass rope, so as to overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: The high-temperature resistant fiberglass rope winding positioning device includes a frame, a support plate, a rotating rod, and a transmission assembly. Two positioning blocks are horizontally and slidably connected to the frame. Positioning chucks are provided on the sides of the two positioning blocks that are close to each other. The support plate is vertically and slidably connected to the frame. The rotating rod is rotatably connected inside the frame. During the rotation of the rotating rod, it has a first stroke and a second stroke. When the rotating rod rotates for the first stroke, it drives the support plate to move vertically upward through the transmission assembly. When the rotating rod rotates for the second stroke, it drives the two positioning blocks to slide horizontally close to each other through the transmission assembly to clamp the two ends of the mandrel.

[0006] Furthermore, the transmission assembly includes a sleeve, the top of which is fixedly connected to the bottom of the support plate. A protrusion is provided inside the sleeve. The rotating rod is provided with a spiral groove, an arc groove, a spiral groove, and an arc groove in sequence. The two ends of one arc groove are respectively connected to the top ends of the two spiral grooves, and the two ends of the other arc groove are respectively connected to the bottom ends of the two spiral grooves.

[0007] Furthermore, an incomplete bevel gear is coaxially fixedly connected to the bottom of the rotating rod. Two sets of teeth are symmetrically arranged on the incomplete bevel gear. Two bevel gear bodies are rotatably connected inside the frame. The two sets of teeth mesh with the two bevel gear bodies in a one-to-one correspondence. A linkage component is provided inside the frame. When the two bevel gear bodies rotate, the linkage component drives the two positioning blocks to slide close together horizontally to clamp the two ends of the mandrel.

[0008] Furthermore, the linkage assembly includes two reciprocating lead screws, with the ends of the two reciprocating lead screws that are close to each other being coaxially and fixedly connected to the ends of the two bevel gear bodies that are far away from each other. A slider is screwed onto each of the two reciprocating lead screws, and the two sliders are horizontally slidably connected in opposite directions within the frame. A connecting bracket is provided at the top of each slider and at the bottom of each positioning block.

[0009] Furthermore, two sliding grooves are symmetrically and horizontally provided inside the frame, and the two sliders are slidably connected in the two sliding grooves respectively.

[0010] Furthermore, a connecting groove is vertically formed on the top of the frame, and the sleeve is vertically slidably connected in the connecting groove, and the cross-section of the sleeve is rectangular.

[0011] Compared with the prior art, the advantages of this utility model are as follows: the high-temperature resistant fiberglass rope winding positioning device rotates the rotating rod. In the first stroke, the transmission component drives the support plate to lift the mandrel to the predetermined position, ensuring that the mandrel is aligned with the positioning chucks on both sides. The mandrel stays at this height. As the rotating rod continues to rotate, in the second stroke, the transmission component drives the two positioning blocks to drive the two positioning chucks to clamp and fix the two ends of the mandrel and center them. No manual lifting is required, and it occupies less space, making it convenient to use and avoiding safety hazards. Attached Figure Description

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0016] Please see Figure 1-6 The present invention provides a technical solution: a high-temperature resistant fiberglass rope winding positioning device, comprising a frame 1, a support plate 5, a rotating rod 8, and a transmission assembly. Two positioning blocks 3 are horizontally and slidably connected on the frame 1, and positioning chucks 4 are provided on the side of the two positioning blocks 3 that are close to each other. The support plate 5 is vertically and slidably connected on the frame 1, and the rotating rod 8 is rotatably connected inside the frame 1. The rotating rod 8 has a first stroke and a second stroke during its rotation. When the rotating rod 8 rotates for the first stroke, it drives the support plate 5 to move vertically upward through the transmission assembly. When the rotating rod 8 rotates for the second stroke, it drives the two positioning blocks 3 to slide horizontally close to each other through the transmission assembly to clamp the two ends of the mandrel. Specifically, the support plate 5 is arc-shaped to prevent the mandrel from slipping off the support plate 5 during the lifting process, which could injure workers or damage equipment.

[0017] In this embodiment, the transmission assembly includes a sleeve 6, the top of which is fixedly connected to the bottom of the support plate 5. A protrusion 7 is provided inside the sleeve 6. A spiral groove 9 and an arc-shaped groove 10 are sequentially formed on the rotating rod 8. One arc-shaped groove 10 has two ends connected to the top ends of the two spiral grooves 9, and the other arc-shaped groove 10 has two ends connected to the bottom ends of the two spiral grooves 9. Specifically, both arc-shaped grooves 10 are horizontally arranged. First, the mandrel is placed on the support plate 5, and the rotating rod 8 is rotated. During the first stroke (the rotating rod 8 rotates 90 degrees), the transmission... Through the sliding engagement of the protrusion 7 with one of the spiral grooves 9, the sleeve 6 is pushed vertically upward, driving the support plate 5 to lift the mandrel to the predetermined position, ensuring that the mandrel is aligned with the positioning chucks 4 on both sides. Continue to rotate the rotating rod 8. In the second stroke (the rotating rod 8 continues to rotate 90 degrees), the protrusion 7 slides into the arc groove 10 at the top, and the mandrel stops at this height, which facilitates the subsequent clamping and fixing of the two ends of the mandrel by the two positioning blocks 3 and the two positioning chucks 4, and aligns them in the center. No manual lifting is required, and it occupies less space, making it convenient to use and avoiding safety hazards.

[0018] In this embodiment, an incomplete bevel gear 11 is coaxially fixedly connected to the bottom of the rotating rod 8. Two sets of teeth are symmetrically arranged on the incomplete bevel gear 11. Two bevel gear bodies 12 are rotatably connected inside the frame 1. The two sets of teeth mesh with the two bevel gear bodies 12 in a one-to-one correspondence. A linkage assembly is provided inside the frame 1. When the two bevel gear bodies 12 rotate, the linkage assembly drives two positioning blocks 3 to slide horizontally close together, clamping both ends of the spindle. The linkage assembly includes two reciprocating screws 13, with one end of the two reciprocating screws 13 close together and connected to the two bevel gear bodies 12. The ends of the two reciprocating screws 13 are coaxially fixedly connected one-to-one. A slider 14 is screwed onto each of the two reciprocating screws 13. The two sliders 14 are horizontally slidably connected within the frame 1 in opposite directions. A connecting bracket 15 is provided at the top of each slider 14 and at the bottom of each positioning block 3. Specifically, in the first stroke, the incomplete bevel gear 11 rotates 90 degrees, and neither of the two gear sets meshes with the two bevel gear bodies 12. At this time, the two positioning blocks 3 do not move. Then, in the second stroke, the incomplete bevel gear 11 continues to rotate 90 degrees, and the two gear sets mesh with the two bevel gear bodies 12, driving the two... The reciprocating screw 13 rotates, driving the two sliders 14 closer together via the screw drive. This, in turn, causes the two positioning blocks 3 to move horizontally closer together via the two connecting brackets 15. The two positioning chucks 4 clamp and fix both ends of the mandrel, simultaneously aligning the mandrel to prevent positional shift during winding. After clamping and fixing the mandrel, the rotating rod 8 can continue to rotate. The protrusion 7 slides into another spiral groove 9, driving the sleeve 6 to move the support plate 5 downwards, facilitating subsequent winding operations. During this process, the two gear sets do not mesh with the two bevel gears. The clamping position of the positioning chuck 4 remains unchanged. After winding is completed, the rotating rod 8 can continue to rotate. The protrusion 7 is slidably connected in the arc-shaped groove 10 below. The height of the support plate 5 remains unchanged. The two tooth groups mesh with the two bevel gear bodies 12, driving the two reciprocating screws 13 to rotate, causing the two sliders 14 to slide horizontally away from each other, so that the two positioning chucks 4 release their clamping and fixing of the mandrel. More specifically, the frame 1 is equipped with a motor 2 for driving the rotation of the incomplete bevel gear 11. The output end of the motor 2 is coaxially and fixedly connected to the bottom end of the incomplete bevel gear 11.

[0019] In this embodiment, two symmetrical horizontal sliding grooves 16 are provided in the frame 1, and two sliders 14 are slidably connected in the two sliding grooves 16 respectively. Specifically, the size of the two sliding grooves 16 is adapted to the size of the two sliders 14. Through the function of the two sliding grooves 16, the axial rotation of the two sliders 14 is restricted, so that the two sliders 14 can only move horizontally in a straight line along the length direction of the corresponding sliding groove 16.

[0020] In this embodiment, a connecting groove is vertically formed on the top of the frame 1, and the sleeve 6 is vertically slidably connected in the connecting groove. The cross-section of the sleeve 6 is rectangular. Specifically, the size of the connecting groove is adapted to the size of the sleeve 6. Through the function of the connecting groove, the axial rotation of the sleeve 6 is restricted, so that the sleeve 6 can only move vertically in a straight line along the length direction of the corresponding connecting groove.

[0021] Working principle: This high-temperature resistant fiberglass rope winding positioning device first places the mandrel on the support plate 5. Rotating the rotating rod 8, in the first stroke, the sliding engagement between the protrusion 7 and one of the spiral grooves 9 pushes the sleeve 6 vertically upward, causing the support plate 5 to lift the mandrel to the predetermined position, ensuring alignment between the mandrel and the positioning chucks 4 on both sides. During the first stroke, the incomplete bevel gear 11 rotates 90 degrees, and neither of the two gear sets meshes with the two bevel gear bodies 12. At this time, the two positioning blocks 3 do not move. Continuing to rotate the rotating rod 8, in the second stroke, the protrusion 7 slides into the top arc groove 10, and the mandrel remains at this height. The incomplete bevel gear 11 continues to rotate 90 degrees, and the two gear sets mesh with the two bevel gear bodies 12, driving the two reciprocating screws 13 to rotate. Through the helical transmission of the reciprocating screws, the two sliders 14 are driven closer together, and through the two connecting brackets 15, the two positioning blocks 3 are moved horizontally. The two positioning chucks 4 clamp and fix the two ends of the mandrel, and can also center and align the mandrel to avoid the winding position shift during the winding process. No manual lifting is required, and it occupies little space, making it convenient to use and avoiding safety hazards. After clamping and fixing the mandrel, the rotating rod 8 can be rotated, and the protrusion 7 slides into another spiral groove 9, driving the sleeve 6 to move the support plate 5 down, which facilitates the subsequent winding operation. During this process, the two tooth groups do not mesh with the two bevel gears, and the clamping position of the two positioning chucks 4 does not change. After the winding is completed, the rotating rod 8 can be rotated again, and the protrusion 7 slides into the arc groove 10 below. The height position of the support plate 5 does not change, and the two tooth groups mesh with the bodies of the two bevel gears 12, driving the two reciprocating screws 13 to rotate, so that the two sliders 14 slide away from each other horizontally, allowing the two positioning chucks 4 to release the clamping and fixing of the mandrel.

[0022] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
