Description

Technical Field

[0001] This invention belongs to the field of structural component conveying technology, specifically an automatic conveying and stacking device for processing bridge steel structural components. Background Technology

[0002] H-beams are important structural components in bridge construction. They are mainly formed by welding steel into frame units, which are then combined into the main body of the bridge. Steel strands are added between the piers to share the load.

[0003] After H-beams are produced, they are typically stacked for easy transport. Generally, each formed H-beam is conveyed out via rollers, then hoisted and stacked onto a transport vehicle. This method results in only one beam being hoisted at a time, and manual assistance is required to straighten it during unloading. The overall stacking operation is slow, and the manual straightening of the beams during unloading and stacking to ensure verticality and stability increases labor intensity, poses safety risks, reduces the efficiency of safe stacking of H-beams, and is inconvenient for transporting the stacked beams. Therefore, to overcome these shortcomings, an automatic conveying and stacking device for bridge steel structure processing is proposed. Summary of the Invention

[0004] To address the problems mentioned in the background art, the present invention provides an automatic conveying and stacking device for processing bridge steel structural components, which solves the problem of low efficiency in the stacking and transportation of existing bridge steel structural components.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic conveying and stacking device for processing bridge steel structural components, comprising a support and an H-beam, and further comprising: a second slide rail assembly installed on the support, wherein a plurality of support mechanisms are equidistantly installed on the second slide rail assembly, and a stacking mechanism is also provided on the support, wherein a driving component is provided at one end of the support, and a plurality of discharge rollers are equidistantly arranged on the driving component; The stacking mechanism includes two sets of slide rail assemblies, a lifting assembly, and an electromagnet. The two sets of slide rail assemblies are symmetrically installed on the support. The lifting assembly is set on the slide rail assembly and its drive can move horizontally. The electromagnets are installed equidistantly below the lifting assembly. The support mechanism and the discharge roller are arranged alternately, and the support mechanism can move in the vertical direction. The stacking mechanism can drive the support mechanism to move to the gap of the discharge roller.

[0006] Preferably, the slide rail assembly two includes two guide rails two symmetrically mounted on the support, each guide rail two having a slider two slidably mounted on it, and each slider two having a bracket fixedly mounted on it. The support mechanism is mounted on the bracket.

[0007] Preferably, a plurality of circular plates are fixedly connected at equal intervals to the outer periphery of the discharge roller, and the outer periphery of the circular plates can be used to support the web portion of the H-beam.

[0008] Preferably, the slide rail assembly includes a guide rail mounted on a support, and a slider is slidably mounted on the guide rail.

[0009] Preferably, the lifting assembly includes a crossbeam fixedly installed on the slider, a hydraulic rod is fixedly connected to the middle of the crossbeam, a connecting seat is fixedly connected to the output end of the hydraulic rod, and an electromagnet is installed at the bottom of the connecting seat. A set of limiting rods are symmetrically fixedly connected to the connecting seat, and the top of the limiting rods can move upward through the crossbeam and be movably connected to it. When the hydraulic rod is in the retracted state, its height is higher than that of the support mechanism.

[0010] Preferably, the support mechanism includes a support plate fixedly installed on the guide rail two, a hydraulic rod two fixedly connected to the top of the support plate, a connecting plate fixedly connected to the top of the hydraulic rod two, a guide rod movably sleeved on one end of the support plate, the top end of the guide rod penetrating the connecting plate and extending above it and fixedly connected to a support plate, a hydraulic support assembly sleeved on the other end of the support plate, the outer periphery of the hydraulic support assembly being fixedly connected to the connecting plate, and the output end of the hydraulic support assembly being fixedly connected to the top of the support plate.

[0011] Preferably, a U-shaped support member is fixedly connected to the bottom of the support plate; The hydraulic support assembly includes a sleeve that is movably fitted onto a support plate. The top end of the sleeve is fixedly connected to a connecting plate. A spring piston rod is fitted onto the sleeve. The top end of the spring piston rod is fixedly connected to a support plate. A one-way valve and a solenoid valve are provided at the bottom end of the sleeve. The U-shaped lifting member supports an oil reservoir. The bottom end of the sleeve can communicate with the oil reservoir through the one-way valve and the solenoid valve. The sleeve can communicate with the oil reservoir in one direction only, and the solenoid valve is in the closed state in the initial state. The sleeve and the oil reservoir store hydraulic oil, and the connecting part between the sleeve and the oil reservoir is a hose.

[0012] Preferably, the top end of the spring piston rod is bolted to the support plate, and the two ends of the spring portion sleeved on the outer periphery of the spring piston rod are located between the support plate and the connecting plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The above scheme uses conveyor rollers to transport the formed H-beams to the bottom of the stacking mechanism. Then, hydraulic rod one extends to push the connecting seat and electromagnet downwards, and the electromagnet attracts the H-beams. Then, hydraulic rod one shortens to make the electromagnet rise, and guide rail one drives slider one to move the electromagnet as a whole to the top of the support mechanism, where the H-beams are stacked on the support mechanism. After the H-beams are stacked, guide rail two drives slider two, the bracket and the support mechanism as a whole to move above the discharge roller. At this time, the height of the support mechanism is lowered to place the H-beams on the discharge roller. At this time, the operator can transport the stacked H-beams by operating the discharge roller, which improves the efficiency of conveying and stacking while also improving the safety of H-beam transportation. In the above scheme, when the H-beam is transported to the support mechanism by the stacking mechanism, the hydraulic rod one needs to extend to push the electromagnet downward. When the H-beam contacts the pallet, it will squeeze the spring piston rod downward. At this time, the hydraulic oil in the sleeve will be discharged into the oil reservoir through the one-way valve. When the electromagnet releases its attraction to the H-beam, the H-beam will remain on the pallet. At this time, the spring outside the spring piston rod is in a compressed state. Its elasticity can support the pallet to maintain the compressed height, so as to facilitate the stacking operation of the stacking mechanism. At the same time, the stroke of the hydraulic rod one is reduced to improve the stacking efficiency. Attached Figure Description

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0017] like Figures 1 to 8 As shown, the present invention provides an automatic conveying and stacking device for processing bridge steel structural components, including a support 1 and an H-beam 7, and further including: a slide rail assembly 2 3 installed on the support 1, a plurality of support mechanisms 4 equidistantly installed on the slide rail assembly 2 3, a stacking mechanism 2 also provided on the support 1, a driving assembly 5 provided at one end of the support 1, and a plurality of discharge rollers 6 equidistantly arranged on the driving assembly 5. The stacking mechanism 2 includes two sets of slide rail assemblies 21, a lifting assembly 22, and an electromagnet 23. The two sets of slide rail assemblies 21 are symmetrically installed on the support 1. The lifting assembly 22 is set on the slide rail assembly 21 and its drive can move horizontally. The electromagnet 23 is installed equidistantly below the lifting assembly 22. The slide rail assembly 21 includes a guide rail 211 mounted on the support 1, and a slider 212 slidably mounted on the guide rail 211. The lifting assembly 22 includes a crossbeam 221 fixedly mounted on the slider 212. A hydraulic rod 223 is fixedly connected to the middle of the crossbeam 221. A connecting seat 222 is fixedly connected to the output end of the hydraulic rod 223. An electromagnet 23 is installed at the bottom of the connecting seat 222. A set of limiting rods 224 are symmetrically fixed to the connecting seat 222. The top of the limiting rods 224 can move upward through the crossbeam 221 and be movably connected to it. When the hydraulic rod 223 is in the retracted state, its height is higher than the height of the support mechanism 4. The support mechanism 4 and the discharge roller 6 are staggered, and the support mechanism 4 can move in the vertical direction. The stacking mechanism 2 can drive the support mechanism 4 to move to the gap of the discharge roller 6. The slide rail assembly 3 includes two guide rails 31 symmetrically mounted on the support 1. Each guide rail 31 is slidably mounted with a slider 32. A bracket 33 is fixedly mounted on each slider 32. The support mechanism 4 is set on the bracket 33. Using the above scheme, the formed H-beams 7 are conveyed to the bottom of the stacking mechanism 2 by the conveying roller. Then, the hydraulic rod 223 extends to push the connecting seat 222 and the electromagnet 23 downward. The electromagnet 23 attracts the H-beams 7. Then, the hydraulic rod 223 shortens to make the electromagnet 23 move upward. The guide rail 211 drives the slider 212 to move the electromagnet 23 to the top of the support mechanism 4 and stack the H-beams 7 on the support mechanism 4. After the H-beams 7 are stacked, the guide rail 31 drives the slider 32, the bracket 33 and the support mechanism 4 to move to the top of the discharge roller 6. At this time, the height of the support mechanism 4 is lowered to place the H-beams 7 on the discharge roller 6. At this time, the operator can transport the stacked H-beams 7 by operating the discharge roller 6, which improves the efficiency of conveying and stacking while also improving the safety of transporting the H-beams 7.

[0018] like Figures 1-3 , Figure 5 and Figure 8 As shown, several circular plates are fixed at equal intervals on the outer periphery of the discharge roller 6, and the outer periphery of the circular plates can be used to support the web portion of the H-beam 7. By adopting the above scheme, the circular plate makes the transport of stacked H-beams 7 more stable, thus preventing the H-beams 7 from dispersing during the transportation process.

[0019] like Figures 2-4 and Figures 6-8 As shown, the support mechanism 4 includes a support plate 41 fixedly installed on the guide rail 31. A hydraulic rod 46 is fixedly connected to the top of the support plate 41. A connecting plate 42 is fixedly connected to the top of the hydraulic rod 46. A guide rod 43 is movably sleeved on one end of the support plate 41. The top end of the guide rod 43 passes through the connecting plate 42 and extends above it and is fixedly connected to a support plate 44. A hydraulic support assembly 45 is sleeved on the other end of the support plate 41. The outer periphery of the hydraulic support assembly 45 is fixedly connected to the connecting plate 42, and the output end of the hydraulic support assembly 45 is fixedly connected to the top of the support plate 44. A U-shaped lifting member 411 is fixedly connected to the bottom of the support plate 41; the hydraulic support assembly 45 includes a sleeve 451 movably sleeved on the support plate 41, the top end of the sleeve 451 is fixedly connected to the connecting plate 42, a spring piston rod 452 is sleeved on the sleeve 451, the top end of the spring piston rod 452 is fixedly connected to the support plate 44, a one-way valve 453 and a solenoid valve 454 are provided at the bottom end of the sleeve 451, the U-shaped lifting member 411 supports an oil reservoir 455, and the bottom end of the sleeve 451 can communicate with the oil reservoir 455 through the one-way valve 453 and the solenoid valve 454; The sleeve 451 can be connected to the oil reservoir 455 in one direction. In the initial state, the solenoid valve 454 is in the closed state. Hydraulic oil is stored in the sleeve 451 and the oil reservoir 455. The connecting part between the sleeve 451 and the oil reservoir 455 is a hose. Using the above scheme, when the H-beam 7 is transported to the support mechanism 4 by the stacking mechanism 2, the hydraulic rod 223 needs to extend to push the electromagnet 23 downward. When the H-beam 7 contacts the pallet 44, it will squeeze the spring piston rod 452 downward. At this time, the hydraulic oil in the sleeve 451 will be discharged into the oil reservoir 455 through the one-way valve 453 for storage. When the electromagnet 23 releases its attraction to the H-beam 7, the H-beam 7 will remain on the pallet 44. At this time, the spring outside the spring piston rod 452 is in a compressed state, and its elasticity can support the pallet 44 to maintain the compressed height, so as to facilitate the stacking operation of the stacking mechanism 2. At the same time, the stroke of the hydraulic rod 223 is reduced to improve the stacking efficiency.

[0020] like Figure 6 and Figure 7 As shown, the top end of the spring piston rod 452 is connected to the support plate 44 by bolts, and the two ends of the spring portion sleeved on the outer periphery of the spring piston rod 452 are located between the support plate 44 and the connecting plate 42. By adopting the above scheme and setting the spring piston rod 452, when the model of the transported stacked H-beam 7 changes, the operator can change the model of the spring to ensure that the device can provide stable support for the H-beam 7, thereby increasing the adaptability of the device.

[0021] Working principle and usage process of this invention: First, the formed H-beam 7 is conveyed to the bottom of the stacking mechanism 2 by the conveying roller. Then, the hydraulic rod 223 extends to push the connecting seat 222 and the electromagnet 23 downward. The electromagnet 23 attracts the H-beam 7. Then, the hydraulic rod 223 shortens to make the electromagnet 23 move upward. The guide rail 211 drives the slider 212 to move the electromagnet 23 to the top of the support mechanism 4 and stack the H-beam 7 on the support mechanism 4. After the H-beam 7 is stacked, the guide rail 31 drives the slider 32, the bracket 33 and the support mechanism 4 to move to the top of the discharge roller 6. At this time, the height of the support mechanism 4 is lowered to place the H-beam 7 on the discharge roller 6. At this time, the operator can transport the stacked H-beam 7 by running the discharge roller 6, which improves the efficiency of conveying and stacking while also improving the safety of transporting the H-beam 7. When the stacking mechanism 2 transports the H-beam 7 to the support mechanism 4, the hydraulic rod 223 needs to extend to push the electromagnet 23 downward. When the H-beam 7 contacts the pallet 44, it will squeeze the spring piston rod 452 downward. At this time, the hydraulic oil in the sleeve 451 will be discharged into the oil reservoir 455 through the one-way valve 453. When the electromagnet 23 releases its attraction to the H-beam 7, the H-beam 7 will remain on the pallet 44. At this time, the spring outside the spring piston rod 452 is in a compressed state. Its elasticity can support the pallet 44 to maintain the height after compression, so as to facilitate the stacking operation of the stacking mechanism 2. When the support mechanism 4 moves to the point where it intersects with the discharge roller 6, the hydraulic rod 46 shortens. At this time, under the limit of the guide rod 43, the hydraulic support assembly 45 moves downward as a whole. The H-beam 7 above the pallet 44 will be replaced by the discharge roller 6, thereby realizing the conveying of the H-beam 7. When the support mechanism 4 moves to its original position, the solenoid valve 454 will open, and the spring piston rod 452 will be reset by the elastic force on it. At this time, the hydraulic oil in the oil reservoir 455 will enter the sleeve 451 through the solenoid valve 454 to facilitate the next operation of the device. When the sleeve 451 is fully reset, the solenoid valve 454 will close.
