Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of structural member conveying, and particularly relates to an automatic conveying and stacking device for bridge steel structural member processing. BACKGROUND

[0002] H-shaped steel is an important structural member in bridge construction, which is mainly formed into a frame unit through steel welding and is combined into a main body of a bridge body for adding steel strand between piers to share load.

[0003] After the production of H-shaped steel is completed, in order to facilitate the transportation thereof, an operator usually performs stacking treatment on the H-shaped steel. In general, each formed H-shaped steel is discharged through a conveying roller, and then is hoisted by hoisting equipment and is stacked on a conveying vehicle. This mode causes only one H-shaped steel to be hoisted each time, and when the hoisted H-shaped steel is unloaded, manual assistance is needed for centering, the overall stacking operation rhythm is slow, and in the process of unloading and stacking, manual centering of the H-shaped steel is usually needed to ensure the perpendicularity and stability of stacking, which not only increases the labor intensity, but also has certain safety risks, reduces the safe stacking efficiency of the H-shaped steel, and is inconvenient for transportation of the H-shaped steel after stacking is completed. Therefore, in order to overcome the above defects, the automatic conveying and stacking device for bridge steel structural member processing is provided. SUMMARY

[0008] Preferably, the second sliding rail assembly comprises two guide rails two symmetrically installed on the support, the two guide rails two are slidably installed with sliding blocks two, and the two sliding blocks two are fixedly installed with a support.

[0009] The support mechanism is arranged on the support.

[0010] Preferably, the outer periphery of the discharging roller is equidistantly fixed with a plurality of circular plates, and the outer periphery of the circular plates can be used to support the web part of the H-shaped steel.

[0011] Preferably, the slide rail assembly comprises a guide rail I mounted on the support, and a sliding block I is slidably mounted on the guide rail I.

[0012] Preferably, the lifting assembly comprises a crosspiece fixedly mounted on the sliding block I, a hydraulic rod I is fixedly connected to the middle part of the crosspiece, a connecting seat is fixedly connected to the output end of the hydraulic rod I, an electromagnet is mounted at the bottom of the connecting seat, a set of limiting rods I are symmetrically fixed to the connecting seat, and the top end of the limiting rods I can pass through the crosspiece in an upward direction and is movably connected to the crosspiece.

[0013] When the hydraulic rod I is in a retracted state, the height thereof is higher than the height of the support mechanism.

[0014] Preferably, the support mechanism comprises a support plate, a hydraulic rod II is fixedly connected to the top of the support plate, a connecting plate is fixedly connected to the top of the hydraulic rod II, a guide rod is movably arranged at one end of the support plate, the top end of the guide rod penetrates through the connecting plate and extends above the connecting plate and is fixedly connected to a supporting plate, and a hydraulic support assembly is arranged at the other end of the support plate, the outer periphery of the hydraulic support assembly is fixedly connected to the connecting plate, and the output end of the hydraulic support assembly is fixedly connected to the top of the supporting plate.

[0015] Preferably, a U-shaped lifting piece is fixedly connected to the bottom of the support plate.

[0016] The hydraulic support assembly comprises a sleeve piece movably arranged on the support plate, the top end of the sleeve piece is fixedly connected to the connecting plate, a spring piston rod is movably arranged on the sleeve piece, the top end of the spring piston rod is fixedly connected to the supporting plate, a one-way valve and an electromagnetic valve are arranged at the bottom end of the sleeve piece, the U-shaped lifting piece supports an oil storage bag, and the bottom end of the sleeve piece can be in communication with the oil storage bag through the one-way valve and the electromagnetic valve.

[0017] The sleeve piece can be in one-way communication with the oil storage bag, and the electromagnetic valve is in a closed state in an initial state.

[0020] Compared with the prior art, the present application has the following advantages:

[0021] 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.

[0022] 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

[0045] By adopting the above scheme, when the H-shaped steel 7 is transported to the supporting mechanism 4 by the stacking mechanism 2, the hydraulic rod one 223 needs to run to be elongated to push the electromagnet 23 to descend, and when the H-shaped steel 7 contacts the supporting plate 44, the spring piston rod 452 is pressed to descend, at this time, the hydraulic oil in the sleeve piece 451 is one-way discharged into the oil storage bag 455 for storage through the one-way valve 453, when the electromagnet 23 is released from the adsorption of the H-shaped steel 7, the H-shaped steel 7 remains on the supporting plate 44, at this time, the spring outside the spring piston rod 452 is in a compressed state, and the elastic force of the spring can support the supporting plate 44 to keep the height after being compressed, so that the stacking operation of the stacking mechanism 2 is facilitated, and the stroke of the hydraulic rod one 223 is reduced to improve the stacking efficiency.

[0046] As shown in Figure 6 and Figure 7 , the top end of the spring piston rod 452 is connected with the supporting plate 44 through bolts, and the two ends of the spring part sleeved on the outer periphery of the spring piston rod 452 are located between the supporting plate 44 and the connecting plate 42;

[0048] The working principle and use process of the present application are as follows:

[0049] Firstly, the formed H-shaped steel 7 is conveyed to the lower side of the stacking mechanism 2 by the conveying roller, then the hydraulic rod one 223 is extended to drive the connecting seat 222 and the electromagnet 23 to move downward, the electromagnet 23 is operated to adsorb the H-shaped steel 7, then the hydraulic rod one 223 is shortened to drive the electromagnet 23 to move upward, the guide rail one 211 is operated to drive the sliding block one 212 to drive the electromagnet 23 to move to the upper side of the supporting mechanism 4 as a whole, and the H-shaped steel 7 is stacked on the supporting mechanism 4, when the H-shaped steel 7 is stacked, the guide rail two 31 is operated to drive the sliding block two 32, the bracket 33 and the supporting mechanism 4 to move to the upper side of the discharging roller 6 as a whole, at this time, the height of the supporting mechanism 4 is lowered to place the H-shaped steel 7 on the discharging roller 6, at this time, the operator can operate the discharging roller 6 to convey the stacked H-shaped steel 7, which improves the conveying and stacking efficiency and the safety of the H-shaped steel 7 during conveying;

[0050] When the stacking mechanism 2 transports the H-shaped steel 7 to the supporting mechanism 4, the hydraulic rod one 223 needs to be operated to extend to drive the electromagnet 23 to move downward, when the H-shaped steel 7 contacts the supporting plate 44, the spring piston rod 452 will be pressed downward, at this time, the hydraulic oil in the sleeve piece 451 will be one-way discharged into the oil storage cavity 455 for storage through the one-way valve 453, when the electromagnet 23 is released from the adsorption of the H-shaped steel 7, the H-shaped steel 7 will remain on the supporting plate 44, at this time, the spring outside the spring piston rod 452 is in a compressed state, and the elastic force of the spring can support the supporting plate 44 to maintain the compressed height, so as to facilitate the stacking operation of the stacking mechanism 2;

[0051] When the supporting mechanism 4 moves to the discharging roller 6 and intersects with it, the hydraulic rod two 46 is operated to shorten, at this time, under the limiting of the guide rod 43, the hydraulic support assembly 45 moves downward as a whole, at this time, the H-shaped steel 7 above the supporting plate 44 will be replaced by the discharging roller 6, so as to realize the conveying of the H-shaped steel 7;

[0052] When the supporting mechanism 4 moves to the original position, the electromagnetic valve 454 is operated to open, the spring piston rod 452 is reset upward under the elastic force thereon, at this time, the hydraulic oil in the oil storage cavity 455 enters the sleeve piece 451 through the electromagnetic valve 454, so as to facilitate the next work of the device, when the sleeve piece 451 is completely reset, the electromagnetic valve 454 is closed.
