Description

Technical Field

[0001] The invention relates to the technical field of cable bridge manufacturing, in particular to an automatic suspension conveying system for cable bridge manufacturing. Background Art

[0002] Cable trays are important supporting carriers in power, communication and industrial pipeline systems and are widely used in construction, transportation, energy and other fields. During the manufacturing process of cable trays, semi-finished products (such as the formed cable tray body, connecting pieces, elbows, etc.) need to be frequently transferred between different processes (such as cutting, welding, surface treatment, assembly, etc.). The transfer efficiency and accuracy directly affect the overall production efficiency and product quality.

[0003] At present, although the traditional hanging conveying device can realize automated transportation, it has the problems of single clamping structure, poor adaptability and easy damage to the bridge due to rigid contact during the clamping process. For example, a cable bridge hanging conveying device with publication number CN212314715U; The above patent content is to use the detachable connection between the telescopic boom and the hanging hole to adjust the distance between the two telescopic booms to meet the hanging requirements of cable trays of different sizes. However, in the actual operation process: First, the spacing adjustment requires manual disassembly and replacement of booms of different lengths or adjustment of the fixed position of the telescopic boom. This operation is cumbersome and time-consuming, affecting the continuity and production efficiency of the conveyor line. Secondly, it only realizes the horizontal suspension transportation of the bridge, and cannot adjust the posture of the bridge (such as the tilt angle, vertical position) according to the process requirements, and cannot meet the various production needs in the cable bridge manufacturing, which greatly affects the automation level of the manufacturing process. Summary of the Invention

[0004] The purpose of the present invention is to realize the automatic suspension transportation of cable trays through the coordinated cooperation of the conveying mechanism and the dynamic clamping mechanism, taking into account the conveying efficiency while meeting various flexible clamping requirements, and being suitable for various application scenarios, which is conducive to significantly improving the automation level of the manufacturing process.

[0006] Furthermore, the dynamic clamping mechanism includes a rectangular positioning frame movably arranged at the front end of the fixed plate, a gear roller is fixedly installed on the top of the rear end of the positioning frame, and the rear end of the gear roller is rotatably connected to the fixed plate, an auxiliary rotating gear is engaged at the adjacent position of the gear roller, and a motor 2 is commonly arranged between the rear end shaft of the auxiliary rotating gear and the vertical plate.

[0007] Furthermore, long material clamping frames are symmetrically arranged at the upper and lower positions of the front end of the positioning frame, and L-shaped slots are provided at both ends of the opposite surfaces of the two groups of the long material clamping frames, and the L-shaped slots at both ends inside the long material clamping frames are rotatably connected to material transfer rollers, and the opposite ends of the upper and lower groups of material transfer rollers extend to the outside of the long material clamping frames.

[0008] Furthermore, a spiral slide frame is provided at the center of the rear end of the long material clamping frame near the upper end. The spiral slide frame is slidably connected to the inside of the vertical groove provided at the front end of the positioning frame. A single-axis motor is provided on the top inner wall of the vertical groove, and a spiral guide rod is fixedly installed on the output shaft at the bottom end of the single-axis motor. The spiral slide frame is spirally sleeved on the outside of the corresponding spiral guide rod.

[0009] Furthermore, the rear ends of the two groups of material transfer rollers in the same row extend to the outside of the material clamping long frame and are fixedly connected with transmission wheels, and a transmission belt is commonly connected between the two groups of transmission wheels in the same row. The rear ends of the upper and lower groups of transmission wheels close to one side are fixedly installed with bevel gears, and the rear ends of each group of bevel gears are respectively engaged with reversing gears. The upper and lower groups of reversing gears are symmetrical in upper and lower directions and are commonly provided with a guide cylinder.

[0010] Furthermore, the guide cylinder is connected to the motor three by a machine base fixedly installed at the bottom position of the rear end of the bottom clamping long frame. The reversing gear near the upper end is slidably sleeved on the outside of the reversing gear, and the reversing gear slides with the vertical groove provided on the outside of the guide cylinder through a slider provided through the groove. The reversing gear near the lower end is fixedly sleeved on the outside of the guide cylinder, and the outside of the guide cylinder is located between the upper and lower sets of reversing gears and is wound with a pressure spring coil.

[0011] Furthermore, a plurality of groups of slots are equidistantly arranged on opposite sides of the upper and lower groups of the clamping long frames, and an inclined frame is hinged equidistantly inside each group of slots, and one end of the inclined frame extends to the outside of the clamping long frame and is rotatably connected to a support plate.

[0012] Furthermore, the inclined frame is extended to an inner end of the long material clamping frame and is provided with an inclined groove. Several groups of positioning cylinders are fixedly installed at equal distances on the inner wall of the two groups of long material clamping frames away from the anti-plate, and a T-shaped vertical rod is provided through the internal opening of the positioning cylinder.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The present invention realizes the automatic suspension conveying of the cable tray through the coordinated cooperation of the conveying mechanism and the dynamic clamping mechanism, wherein the conveying mechanism can smoothly convey the cable tray through the coordinated work of components such as the slide rod, the long slide frame, the transmission gear, the transmission chain, the positioning block and the concave clamping frame; The present invention also provides a dynamic clamping mechanism. First, a single-axis motor drives the spiral guide rod to rotate, forcing the spiral slide frame to slide up and down in the vertical slot, thereby driving the upper clamping long frame to move synchronously, and adjusting the distance between the two sets of clamping long frames to adapt to cable trays of different thicknesses. Secondly, the two sets of reversing gears rotate and drive the bevel gear and the transmission wheel connected to it to rotate. The transmission wheel transmits power to the other set of transmission wheels in the same row through the transmission belt, realizing the synchronous rotation of the two sets of material transfer rollers. This not only helps to transfer the cable bridge to the two sets of material clamping long frames for feeding, but also facilitates the subsequent downward transmission of the cable bridge at the material clamping long frames for unloading. Finally, during the cable clamping or transmission process, the cable tray squeezes the corresponding disc, and the inclined frame rotates around the hinge point, driving the T-shaped upright to stretch. The movement of the T-shaped upright causes the circular shaft to slide in the inclined groove, and at the same time stretches the second coil of the pressure spring and produces deformation, thus achieving dynamic clamping of the cable tray and avoiding damage caused by rigid clamping. This dynamic clamping mechanism not only adapts to cable trays of different specifications and sizes, but also takes into account the conveying efficiency while meeting a variety of flexible clamping requirements. It is suitable for a variety of application scenarios and is conducive to significantly improving the level of automation in the manufacturing process. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0018] Example 1: Please refer to Figure 1-Figure 2 As shown, an automated hanging conveying system for manufacturing cable trays includes a conveying frame 1, a conveying mechanism 2 is provided inside the conveying frame 1, the conveying mechanism 2 includes slide bars 21 symmetrically arranged on both sides of the front end of the conveying frame 1, a long slide frame 22 is slidably connected between the two sets of slide bars 21, and fixed plates 23 are fixedly installed on both sides of the rear end inside the conveying frame 1, and transmission gears 24 are rotatably provided at the upper and lower positions of the front ends of the two sets of fixed plates 23; A motor 25 is provided at the rear end shaft of one group of transmission gears 24, and a transmission chain 26 is meshed with each other on the outside of the four groups of transmission gears 24. A positioning block 27 is hinged at the bottom center of the front end of the transmission chain 26. The front end of the positioning block 27 passes through the long sliding frame 22 and is fixedly installed with a concave card frame 28. A vertical plate 29 is rotatably connected inside the concave card frame 28, and the shaft of the vertical plate 29 is rotatably connected to the inner side wall of the concave card frame 28. A dynamic clamping mechanism 3 is movably provided at the front end of the vertical plate 29.

[0019] The specific conveying process includes: starting the motor 1 25 to drive one of the transmission gears 24 to rotate. Since the four transmission gears 24 are meshed with the transmission chain 26, the four transmission gears 24 will rotate synchronously, thereby driving the transmission chain 26 to drive, and the long slide frame 22 slides up and down along the slide rod 21 through the positioning block 27; At the same time, the concave card frame 28, the vertical plate 29 and the dynamic clamping mechanism 3 are driven to move in a circular manner, and the cable tray is placed on the dynamic clamping mechanism 3. The cable tray is clamped and fixed by the dynamic clamping mechanism 3. As the concave card frame 28 moves, the cable tray can be driven to be transported; This structure realizes automatic hanging transportation of the cable tray by means of the provided conveying mechanism 2, which reduces the labor intensity of the staff and improves the transportation efficiency of the cable tray.

[0020] Example 2: Please refer to Figure 3-Figure 7 As shown, the dynamic clamping mechanism 3 includes a rectangular positioning frame 31 movably arranged at the front end of the vertical plate 29, a gear roller 32 is fixedly installed on the top of the rear end of the positioning frame 31, and the rear end of the gear roller 32 is rotatably connected to the fixed plate 23, an auxiliary rotating gear 33 is meshed with the adjacent position of the gear roller 32, and a motor 2 34 is commonly provided between the shaft at the rear end of the auxiliary rotating gear 33 and the vertical plate 29; The second starting motor 34 drives the auxiliary rotating gear 33 to rotate, and the auxiliary rotating gear 33 drives the gear roller 32 meshing with it to rotate synchronously. The rotation of the gear roller 32 causes the positioning frame 31 and the entire set of dynamic clamping mechanism 3 to deflect, thereby achieving the angle adjustment of the dynamic clamping mechanism 3 to adapt to the handling requirements of cable trays of different heights or angles; The front end of the positioning frame 31 is symmetrically provided with long material clamping frames 35 at the upper and lower positions. L-shaped slots are provided at both ends of the opposite surfaces of the two sets of long material clamping frames 35, and the L-shaped slots at both ends of the interior of the long material clamping frames 35 are rotatably connected to material transfer rollers 36. The opposite ends of the upper and lower sets of material transfer rollers 36 extend to the outside of the long material clamping frames 35. A spiral slide frame 37 is provided near the center of the rear end of the upper end long material clamping frame 35. The spiral slide frame 37 is slidably connected to the inside of the vertical slot provided at the front end of the positioning frame 31. A single-axis motor 38 is provided on the inner wall of the top of the vertical slot, and a spiral guide rod 39 is fixedly installed on the output shaft of the bottom end of the single-axis motor 38. The spiral slide frame 37 is spirally sleeved on the outside of the corresponding spiral guide rod 39; The rear ends of the two sets of material transfer rollers 36 in the same row extend to the outside of the material clamping long frame 35 and are fixedly connected to the transmission wheel 310. A transmission belt is commonly connected between the two sets of transmission wheels 310 in the same row. The rear ends of the upper and lower sets of transmission wheels 310 near one side are fixedly installed with bevel gears 311. The rear ends of each set of bevel gears 311 are respectively engaged with a reversing gear 312. The upper and lower sets of reversing gears 312 are symmetrical and are commonly provided with a guide cylinder 313. The guide cylinder 313 is connected to the motor 314 provided on the machine base fixedly mounted at the bottom rear end of the bottom clamping long frame 35. The reversing gear 312 near the upper end is slidably sleeved on the outside of the reversing gear 312, and the reversing gear 312 slides through the vertical slot provided on the outside of the guide cylinder 313 through a slider provided through the slot. The reversing gear 312 near the lower end is fixedly sleeved on the outside of the guide cylinder 313. A pressure spring coil 315 is wound around the outside of the guide cylinder 313 and located between the upper and lower sets of reversing gears 312. The clamping execution module processing specifically includes the following steps: (1) When clamping a cable tray placed horizontally at a high place: first, the dynamic clamping mechanism 3 is raised and moved to the level of the handling point through the conveying mechanism 2, ensuring that the positioning frame 31 corresponds to the left and right of the cable tray. Then, one end of the cable tray is pressed against the transfer roller 36 at one end of the top surface of the bottom clamping long frame 35, and then the single-axis motor 38 is started to drive the spiral guide rod 39 to rotate, forcing the spiral slide frame 37 to slide up and down in the vertical groove, thereby driving the upper end clamping long frame 35 to move synchronously, and adjusting the distance between the two sets of clamping long frames 35 to adapt to cable trays of different thicknesses; After the adjustment of the spacing between the clamping long frames 35 is completed, the motor 314 is started again, and the upper and lower sets of reversing gears 312 are driven to rotate through the guide cylinder 313. The rotation of the reversing gear 312 drives the bevel gear 311 and the transmission wheel 310 connected thereto to rotate. The transmission wheel 310 transmits power to the other set of transmission wheels 310 in the same row through the transmission belt, thereby realizing the synchronous rotation of the two sets of material transfer rollers 36, which not only helps to transmit the cable bridge to the space between the two sets of material clamping long frames 35 for feeding, but also facilitates the subsequent downward transmission and unloading of the cable bridge at the material clamping long frame 35; It is worth mentioning that during the clamping process, the bevel gear 311 at the upper end sinks synchronously with the long clamping frame 35 and presses the corresponding reversing gear 312 to sink. At this time, the reversing gear 312 slides downward along the vertical groove set on the outside of the guide cylinder 313 and compresses the pressure spring coil 1 315, causing it to deform and store elastic potential energy, thereby ensuring that the reversing gear 312 drives the bevel gear 311 to continuously engage.

[0021] In addition, a plurality of groups of card slots are equidistantly provided on the opposite surfaces of the upper and lower groups of material clamping frames 35, and an inclined frame 316 is hingedly connected at an equal distance inside each group of card slots, and one end of the inclined frame 316 extends to the outside of the material clamping frame 35 and is rotatably connected to a stop plate 317, and an inclined slot is provided at one end of the inclined frame 316 extending to the inside of the material clamping frame 35, and a plurality of groups of positioning cylinders 318 are fixedly installed at equal distances on the inner wall of the two groups of material clamping frames 35 on the side away from the stop plate 317, and a T-shaped vertical rod 319 is provided through the opening of the positioning cylinder 318, and a pressure spring coil 320 is wound around the outside of the T-shaped vertical rod 319 and inside the positioning cylinder 318, and a round shaft 321 is fixedly installed on one end of the T-shaped vertical rod 319 extending to the positioning cylinder 318, and the round shaft 321 is clamped in the corresponding inclined slot; Therefore, during the cable clamping or transmission process, the cable tray squeezes the corresponding abutment plate 317, and the inclined frame 316 rotates around the hinge point, driving the T-shaped upright 319 to stretch. The movement of the T-shaped upright 319 causes the circular shaft 321 to slide in the inclined groove, and at the same time stretches the second coil of the pressure spring 320 and produces deformation, thereby achieving dynamic clamping of the cable tray and avoiding damage caused by rigid clamping. During unloading, when the cable tray is transmitted to the specified position, the motor 314 is turned off, and the elastic potential energy of the pressure spring coil 320 is released, pushing the T-shaped vertical rod 319 to reset, thereby driving the circular shaft 321 and the inclined frame 316 to reset, thereby realizing the unloading of the cable tray. This structure not only realizes the dynamic clamping of the cable tray, but also simplifies the transmission and unloading process of the cable tray, significantly improving work efficiency. (2) When it is necessary to clamp the cable tray placed on the ground: flip the vertical plate 29 to rotate the dynamic clamping mechanism 3 90° and adjust it to the upper and lower corresponding state of the cable tray. The above clamping steps can be used to complete the transportation, thereby realizing the clamping and transportation of cable trays in various application scenarios, effectively enhancing the practicality of the device.

[0022] Working principle: When the present invention is in use, the dynamic clamping mechanism 3 is first moved to the cable tray to be clamped through the conveying mechanism 2. According to the position and state of the cable tray, the angle and height of the dynamic clamping mechanism 3 are adjusted to ensure that it can accurately clamp the cable tray. Subsequently, the various components of the dynamic clamping mechanism 3 are driven to work together. Driven by the transmission wheel 310 and the transmission belt, the long clamping frame 35 gradually approaches the cable tray and clamps it between the two groups of long clamping frames 35. At the same time, the inclined frame 316 is adaptively adjusted according to the shape and size of the cable tray to ensure that the cable tray is not damaged during the clamping process. After the clamping is completed, the conveying mechanism 2 continues to work, driving the dynamic clamping mechanism 3 and the clamped cable tray to move. According to needs, the conveying direction of the conveying mechanism 2 is adjusted to meet the needs under different working conditions. When the cable tray is transported to the specified position, the dynamic clamping mechanism 3 stops working. At this time, the elastic potential energy of the pressure spring coil 320 is released, pushing the T-shaped vertical rod 319, the round shaft 321 and the inclined frame 316 to reset, thereby realizing the unloading of the cable tray.
