Description

Technical Field

[0001] This utility model relates to the field of glass fiber tube production technology, and in particular to a glass fiber tube traction machine. Background Technology

[0002] Fiberglass reinforced plastic (BWFRP) pipe is a new type of cable protection sleeve made from alkali-free glass fiber and resin through a continuous online braiding, winding, and pultrusion molding process. Due to its advantages such as high strength, corrosion resistance, and good insulation performance, it is widely used in municipal engineering, urban power grids, and rail transit.

[0003] In the production process of fiberglass tubes, a transport device is required to convey the tubes. Patent number CN202220727508.1, entitled "A BWFRP Pultrusion Tube Transport Device," describes a device that uses a clamping module and a drive module to transport the fiberglass tubes. The clamping module consists of at least two components: a gantry frame, a lower clamp, an upper clamp, and a hydraulic or pneumatic cylinder. During clamping, the hydraulic or pneumatic cylinder drives the upper clamp to move downwards along a guide post, cooperating with the lower clamp to clamp the tube. The stepper motor in the drive module drives a lead screw to rotate, causing a threaded slide plate to move along a guide rail, thereby transporting the clamping module and the tube forward.

[0004] However, there are some shortcomings in the existing technology. The lower clamp is fixed to the gantry base plate. When the upper clamp separates from the fiberglass tube, the upper side of the lower clamp contacts the fiberglass tube. If the drive module moves the gantry and fiberglass tube in opposite directions to reset, the lower clamp and fiberglass tube will move relative to each other and rub against each other, which can easily scratch the lower side of the fiberglass tube. Even with internal elastic pads to reduce damage, the elastic pads will still move relative to each other, causing some friction damage and affecting the appearance quality of the fiberglass tube. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a glass fiber tube traction machine that can ensure the appearance quality of the glass fiber tube.

[0006] To solve the above-mentioned technical problems, the present invention provides a glass fiber tube traction machine, including a conveying frame and a plurality of traction components arranged at intervals along the glass fiber tube conveying direction on the conveying frame. The traction components include a clamping frame slidably connected to the conveying frame, a translation drive device mounted on the conveying frame for driving the clamping frame to move back and forth, a lower clamping block slidably connected to the clamping frame, an upper clamping block located above the lower clamping block for cooperating with the lower clamping block and clamping the glass fiber tube, a clamping drive device mounted on the clamping frame for driving the upper clamping block to move up and down, and a linkage device mounted on the clamping frame for driving the lower clamping block and the upper clamping block to move in opposite directions.

[0007] As an improvement to the above solution, the linkage device includes a drive rod fixed to the output end of the clamping drive device and extending downward, and a rocker arm hinged to the clamping frame in the middle. The left part of the rocker arm is located below the drive rod, and the right part of the rocker arm is used to lift the lower clamping block.

[0008] As an improvement to the above solution, the lower clamping block is provided with a clearance groove for the right side of the rocker arm to extend into.

[0009] As an improvement to the above solution, the lower end of the drive rod is rotatably connected to a first roller for abutting against the left side of the rocker arm, and the right end of the rocker arm is provided with a second roller for abutting against the clearance groove.

[0010] As an improvement to the above solution, the linkage device also includes a return spring that is connected at both ends to the clamping frame and the right side of the rocker arm, respectively.

[0011] As an improvement to the above solution, the clamping frame is provided with an upwardly extending guide rail, the lower clamping block is provided with a guide groove for sliding connection with the guide rail, and the upper clamping block is threadedly connected to the clamping drive device.

[0012] As an improvement to the above solution, the lower side of the upper clamping block is provided with an upper arc concave surface for abutting against the upper side of the glass fiber tube, and the upper side of the lower clamping block is provided with a lower arc concave surface for abutting against the lower side of the glass fiber tube. The inner diameter of the upper arc concave surface is the same as the inner diameter of the lower arc concave surface.

[0013] As an improvement to the above solution, the clamping drive device includes a translation frame that is slidably connected to the clamping frame and a clamping drive hydraulic cylinder that is mounted on the clamping frame and whose output end is connected to the translation frame. The drive rod is fixedly mounted on the translation frame, and the upper clamping block is threadedly connected to the translation frame.

[0014] As an improvement to the above solution, the translation drive device includes a translation drive hydraulic cylinder mounted on the conveyor frame and whose output end is connected to the clamping frame.

[0015] As an improvement to the above solution, the translation drive device further includes a distance sensor mounted on the conveyor frame and used to detect the position of the conveyor frame, the distance sensor being communicatively connected to the translation drive hydraulic cylinder.

[0016] Implementing this utility model has the following beneficial effects:

[0017] The glass fiber tube traction machine of this utility model uses a conveyor frame, a clamping frame, a translation drive device, a lower clamping block, an upper clamping block, a clamping drive device, and a linkage device to work together so that when the translation drive device drives the clamping frame to move forward and reset, the upper and lower clamping blocks remain separated from the glass fiber tube, avoiding frictional damage to the glass fiber tube and ensuring the appearance quality of the glass fiber tube.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] like Figures 1 to 5 As shown in the figure, a fiberglass tube traction machine according to an embodiment of the present invention includes a conveyor frame 100 and a plurality of traction components arranged at intervals along the conveying direction of the fiberglass tube on the conveyor frame 100. In practice, there should be at least two sets of traction components, used to clamp the outer side of the fiberglass tube and drive the fiberglass tube to move from front to back, thereby realizing the forward-to-back conveying of the fiberglass tube. Taking two sets of traction components as an example, its working principle is as follows: First, one set of traction components clamps the fiberglass tube and drives it to move from front to back, while the other set of traction components releases the fiberglass tube and remains in place; after conveying a certain distance, the other set of traction components clamps the fiberglass tube and continues to convey it from front to back, while the initially clamping set of traction components moves forward and resets after releasing the fiberglass tube. In this way, the two sets of traction components work alternately to achieve continuous conveying of the fiberglass tube.

[0036] The traction assembly includes a clamping frame 200 that is slidably connected to the conveyor frame 100, a translation drive device 300 mounted on the conveyor frame 100 for driving the clamping frame 200 to move back and forth, a lower clamping block 400 that is slidably connected to the clamping frame 200, an upper clamping block 500 located above the lower clamping block 400 and used to cooperate with the lower clamping block 400 and clamp the glass fiber tube, a clamping drive device 600 mounted on the clamping frame 200 for driving the upper clamping block 500 to move up and down, and a linkage device 700 mounted on the clamping frame 200 for driving the lower clamping block 400 and the upper clamping block 500 to move in opposite directions. In fact, the translation drive device 300 can be a hydraulic push rod, a motor and a lead screw and slider pair, etc., which can drive the clamping frame 200 to move back and forth; the clamping drive device can be a hydraulic push rod, a pneumatic push rod, a motor and a lead screw and slider pair, or a cam mechanism, etc., which can drive the upper clamping block 500 to move up and down; the linkage device 700 can be a rack and pinion (two racks are set on both sides of the gear), a lead screw and slider (the lead screw has two threaded sections with opposite directions of rotation, and two sliders are respectively threaded to the two threaded sections), etc., which can drive the lower clamping block 400 to move in the opposite direction to the upper clamping block 500.

[0037] The specific clamping principle of the glass fiber tube traction machine of this utility model is as follows: When it is necessary to clamp the glass fiber tube, the clamping drive device 600 drives the upper clamping block 500 to move downward; under the action of the linkage mechanism, the lower clamping block 400 also moves upward until the upper clamping block 500 and the lower clamping block 400 jointly clamp the outer side of the glass fiber tube; at this time, the translation drive device 300 is activated, driving the glass fiber tube clamped on the clamping frame 200 to move from front to back; after the glass fiber tube has been conveyed a certain distance, Another set of traction components begins to operate; simultaneously, in the initially clamped set of traction components, the clamping drive device 600 drives the upper clamping block 500 to move upward, and the linkage mechanism causes the lower clamping block 400 to move downward, so that both the upper clamping block 500 and the lower clamping block 400 are separated from the glass fiber tube; subsequently, the translation drive device 300 drives the clamping frame 200 to move forward and reset, so that both the upper clamping block 500 and the lower clamping block 400 remain separated from the glass fiber tube to avoid frictional damage to the glass fiber tube.

[0038] The glass fiber tube traction machine of this utility model uses a conveyor frame 100, a clamping frame 200, a translation drive device 300, a lower clamping block 400, an upper clamping block 500, a clamping drive device 600, and a linkage device 700 to cooperate with each other. When the translation drive device 300 drives the clamping frame 200 to move forward and reset, the upper clamping block 500 and the lower clamping block 400 are both kept separated from the glass fiber tube, avoiding frictional damage to the glass fiber tube and ensuring the appearance quality of the glass fiber tube.

[0039] It should be noted that the linkage device 700 preferably includes a drive rod 710 fixed to the output end of the clamping drive device 600 and extending downward, and a rocker arm 720 hinged to the clamping frame 200 in the middle. The left part of the rocker arm 720 is located below the drive rod 710, and the right part of the rocker arm 720 is used to lift the lower clamping block 400. Initially, as Figure 5 The upper clamping block 500 and the lower clamping block are in a separated state, and the lower end of the drive rod 710 is located above the left side of the rocker arm 720. When the clamping drive component drives the upper clamping block 500 and the drive rod 710 to move downwards until the lower end of the drive rod 710 contacts the left side of the rocker arm 720, the left side of the rocker arm 720 tilts up, causing the lower clamping block 400 to move upwards until the upper clamping block 500 and the lower clamping block 400 cooperate to clamp the outer side of the glass fiber tube. Figure 2 As shown. When it is necessary to release the fiberglass tube, the clamping drive component drives the upper clamping block 500 and the drive rod 710 to move upward, while the lower clamping block 400 slides down under gravity, causing the right side of the rocker arm 720 to swing downward and the left side of the rocker arm 720 to swing upward and abut against the lower end of the drive rod 710. As the drive rod 710 continues to move upward until the lower clamping block 400 returns to its original position and the lower end of the drive rod 710 separates from the left side of the rocker arm 720, the clamping drive component drives the upper clamping block 500 to continue moving upward until it returns to its original position. The linkage device 700 can make the lower clamping block 400 and the upper clamping block 500 separate from the outside of the fiberglass tube synchronously.

[0040] Specifically, the lower clamping block 400 preferably has a clearance groove 410 for the right part of the rocker arm 720 to extend into, providing clearance space for the movement of the right part of the rocker arm 720, ensuring that the right part of the rocker arm 720 can lift the lower clamping block 400 when it is raised and can press down the right part of the rocker arm 720 when it is lowered.

[0041] More specifically, the lower end of the drive rod 710 is preferably rotatably connected to a first roller 730 for abutting against the left side of the rocker arm 720, and the right end of the rocker arm 720 is provided with a second roller 740 for abutting against the clearance groove 410. When the clamping drive component drives the upper clamping block 500 and the drive rod 710 to move downward, the first roller 730 contacts and rolls with the left side of the rocker arm 720, causing the left side of the rocker arm 720 to be pressurized and rocked up, driving the lower clamping block 400 to move upward, thereby clamping the glass fiber tube; at the same time, the second roller 740 extends into the clearance groove 410 of the lower clamping block 400. When the lower clamping block 400 slides down under the action of gravity, the second roller 740 contacts and rolls with the upper edge of the clearance groove 410, making the lower clamping block 400 move downward more smoothly, thereby achieving synchronous separation from the upper clamping block 500. By using rolling friction instead of sliding friction, the frictional resistance between the drive rod 710 and the rocker arm 720, and between the rocker arm 720 and the lower clamping block 400, is reduced, making the clamping and releasing actions smoother.

[0042] More specifically, the linkage device 700 preferably includes a return spring 750 connected at both ends to the clamping frame 200 and the right side of the rocker arm 720, respectively. When the clamping drive component moves the upper clamping block 500 and the drive rod 710 downward, the first roller 730 at the lower end of the drive rod 710 contacts and rolls with the left side of the rocker arm 720, causing the left side of the rocker arm 720 to lift up, driving the lower clamping block 400 to move upward and clamp the glass fiber tube, while the return spring 750 is stretched. When it is necessary to release the glass fiber tube, the clamping drive component moves the upper clamping block 500 and the drive rod 710 upward, and the return spring 750 pulls the right side of the rocker arm 720 under its own elasticity, causing the left side of the rocker arm 720 to swing upward, assisting the lower clamping block 400 to slide smoothly down under the action of gravity, thereby separating the lower clamping block 400 from the glass fiber tube. The tension generated by the elastic deformation of the return spring 750 ensures that the rocker arm 720 is reset in time during the release process, improving the continuity and reliability of the clamping and releasing actions.

[0043] It is worth mentioning that the clamping frame 200 preferably has an upwardly extending guide rail 210, the lower clamping block 400 has a guide groove 420 for sliding connection with the guide rail 210, and the upper clamping block 500 is threadedly connected to the clamping drive device 600. The lower clamping block is detachably connected to the clamping frame 200 by matching the guide rail 210 with the guide groove 420, and the upper clamping block 500 is also detachably connected to the clamping drive device, allowing for the replacement of different upper clamping blocks 500 and lower clamping blocks 400 to adapt to different glass fiber tubes.

[0044] Specifically, the upper clamping block 500 preferably has an upper arc-shaped concave surface 510 on its lower side for abutting against the upper side of the fiberglass tube, and the lower clamping block 400 has a lower arc-shaped concave surface 430 on its upper side for abutting against the lower side of the fiberglass tube. The inner diameter of the upper arc-shaped concave surface 510 is the same as the inner diameter of the lower arc-shaped concave surface 430. The arrangement of the upper arc-shaped concave surface 510 and the lower arc-shaped concave surface 430 ensures a tight fit between the clamping surface and the outer surface of the fiberglass tube, thereby providing uniform support force during clamping and effectively preventing deformation or damage to the tube during clamping. Furthermore, by replacing the upper clamping block 500 and lower clamping block 400 with different inner diameters, various specifications of fiberglass tubes can be accommodated, enhancing the versatility and adaptability of the fiberglass tube traction machine.

[0045] Preferably, the clamping drive device 600 includes a translation frame 610 that is slidably connected to the clamping frame 200 and a clamping drive hydraulic cylinder 620 that is mounted on the clamping frame 200 and whose output end is connected to the translation frame 610. The drive rod 710 is fixedly mounted on the translation frame 610, and the upper clamping block 500 is threadedly connected to the translation frame 610. The clamping drive hydraulic cylinder 620 provides a stable and sufficient driving force to ensure that the upper clamping block 500 moves smoothly up and down, thereby realizing reliable clamping and releasing of the glass fiber tube.

[0046] Preferably, the translation drive device 300 includes a translation drive hydraulic cylinder 310 mounted on the conveyor frame 100 and connected at its output end to the clamping frame 200. The translation drive hydraulic cylinder 310 provides stable and sufficient driving force to drive the clamping frame 200 to move smoothly back and forth, thereby realizing the front-to-back transport of the fiberglass tube. Further, the translation drive device 300 preferably also includes a distance sensor 320 mounted on the conveyor frame 100 for detecting the position of the conveyor frame 100. The distance sensor 320 is communicatively connected to the translation drive hydraulic cylinder 310. In practice, the fiberglass tube traction machine of this invention can also be equipped with a control component to realize the communicative connection between the distance sensor 320 and the translation drive hydraulic cylinder 310. During operation, the distance sensor 320 can measure the moving distance of the clamping frame 200 and feed the data back to the control component. The control component controls the working state of the translation drive hydraulic cylinder 310 according to the preset moving distance, thereby realizing the control of the position of the clamping frame 200, ensuring the accurate positioning and movement of the clamping frame 200 during the conveying process, and improving the level of automation.
