By adding a longitudinal angle adjustment mechanism to the horizontal conveying path of the steel sections, and arranging a transverse anti-skid mechanism on the longitudinal angle adjustment mechanism, and arranging multiple sets of steel section guide mechanisms in the anti-skid mechanism, when the steel sections pass through the multiple sets of steel section guide mechanisms and need to be transferred laterally, the anti-skid mechanism will cooperate with the multiple sets of steel section guide mechanisms to provide free tilt support for the placed steel sections. When the lateral feeding assembly tilts and pushes the steel sections laterally, the transfer of the steel sections can be accelerated, thereby avoiding wear of the steel sections due to lateral transfer.

Description

Technical Field

[0001] The present invention relates to the technical field of section steel transportation, in particular to a direction-changing mechanism for transporting section steel on an AGV forklift portal frame. Background Art

[0002] Forklift mast steel is mainly used for the inner and outer masts of the forklift lifting parts. It is mainly made of hot-rolled steel and has high requirements for strength, toughness and dimensional accuracy. Its stability directly affects the service life of the mast rollers, pulleys and lifting cylinders.

[0003] At present, the transportation of steel materials is mainly carried out by conveyor rollers. Since the steel itself is heavy, the friction resistance between the steel and the conveyor roller is extremely large during the transfer on the conveyor roller. When the steel needs to be transferred laterally, the conveyor roller is likely to cause wear or scratches on the bottom surface of the steel. At the same time, as the steel continues to contact the surface of the conveyor roller, impurities on the surface of the steel will accumulate on the surface of the conveyor roller, which may cause the conveyor roller to rust more severely.

[0004] In view of this, a direction-changing mechanism for AGV forklift gantry steel transportation was designed to solve the above problems. Summary of the Invention

When the multiple sets of steel guide mechanisms are tilted upward and as the inclination angle gradually increases, the steel sections on the multiple sets of steel guide mechanisms can be protected from falling by the guard plates when they are delivered upward. The evenly distributed multiple sets of pressing plates will be in an inclined state during the transverse movement along the outer end of the pipe segment, thereby enhancing the oblique angle protection of the steel sections delivered upward.

[0043] To make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0044] It is to be understood that these descriptions are illustrative only and are not intended to limit the scope of the invention.

[0045] The following describes a direction-changing mechanism for transporting steel sections on an AGV forklift gantry, provided by some embodiments of the present invention, with reference to the accompanying drawings.

[0046] Example 1:

[0047] Combine Figures 1 to 9 As shown, the present invention provides a direction-changing mechanism for conveying steel sections on an AGV forklift gantry, comprising a longitudinal angle adjustment mechanism 100, an anti-skid mechanism 200 arranged on the longitudinal angle adjustment mechanism 100, a guide energy supply mechanism 300 arranged in the anti-skid mechanism 200, and a plurality of steel section guide mechanisms 400 arranged in the anti-skid mechanism 200. The longitudinal angle adjustment mechanism 100 is used to adjust the inclination angle of the anti-skid mechanism 200, the anti-skid mechanism 200 is used to provide effective support for the plurality of steel section guide mechanisms 400, and the guide energy supply mechanism 300 cooperates with the plurality of steel section guide mechanisms 400 to deliver the inclined steel sections laterally.

[0048] The longitudinal angle adjustment mechanism 100 includes a base 110;

[0049] The anti-skid mechanism 200 includes a pad 250 movably mounted on the top of the base 110 , a beam 220 mounted on the top of the pad 250 , and a bearing 230 disposed in an internal hole of the beam 220 ;

[0050] The steel guide mechanism 400 includes a shaft 410 disposed within a bearing 230, a linkage gear 420 disposed on the shaft 410, two stopper holes 430 formed in the truncated cone-shaped end surface of the shaft 410, four tube segments 440 mounted on the outer ends of the shaft 410, a head 450 mounted on the outer ends of the four tube segments 440, multiple sets of side feed assemblies 480 disposed within the four tube segments 440, and two trusses 470 disposed on the multiple sets of side feed assemblies 480.

[0051] The side feeding assembly 480 is used to provide anti-fall protection for the steel sections delivered at an angle;

[0052] The side feeding assembly 480 includes an inner gasket 4801 movably mounted on the inner sides of the four tube segments 440, a third clamp 4806 movably mounted on the inner sides of the inner gasket 4801, a spring 4807 disposed outside the third clamp 4806 and bearing pressure on the inner gasket 4801, four first clamps 4802 fixedly mounted on one side of the inner gasket 4801, an inclined bracket 4803 movably mounted on the outer ends of the first clamps 4802, a second clamp 4804 movably mounted on the other end of the inclined bracket 4803, a slip ring 4805 movably mounted on the outer sides of the four tube segments 440, and a fourth clamp 48061 mounted on the slip ring 4805.

[0053] The inner wall of the slip ring 4805 is provided with four limiting grooves 4809 , and the connecting end of the oblique bracket 4803 and the second clamp 4804 is located in the limiting grooves 4809 ;

[0054] A pressing piece 4808 is movably mounted on the other end of the second clamp 4804 and the other end of the fourth clamp 48061;

[0055] Both ends of the pressing piece 4808 are provided with outward-facing inclined surfaces. When the pressing piece 4808 is tilted, the ends of the outward-facing inclined surfaces are used to scrape off the agglomerated dirt on the second chuck 4804.

[0056] The interior of the truss 470 is provided with a transverse groove;

[0057] Sector-shaped slots are formed on both sides of the built-in gasket 4801 , and the truss 470 is installed in the sector-shaped slots.

[0058] When the beam plate 220 cooperates with the pad 250 to flip sideways along the top of the base 110, the horizontal steel guide mechanism 400 assembled in the beam plate 220 by the bearing 230 can be tilted as a whole. As the inclination angle of the multiple sets of steel guide mechanisms 400 is adjusted, the truss 470 will push the multiple built-in gaskets 4801 to move laterally along the inner sides of the four pipe segments 440. At the same time, the four first clamps 4802 installed on the built-in gaskets 4801 will push the inclined frame 4803 and the second clamp 4804 to extend until the truss 470 applies pressure to two of the inclined frames 4803 in a set of side feeding assemblies 480. At this time, the four pipe segments 440 will apply reverse resistance to the built-in gaskets 4801. At this time, the end of the pressing plate 4808 facing the steel will tilt toward the pipe segment 440, and the tilted pressing plate 4808 can provide effective support and anti-fall-off protection for the steel. Finally, the delivered steel can be safely transferred to the selected conveying platform.

[0059] During the lateral movement of the slip ring 4805, the dirt accumulated on the outside of the four pipe segments 440 can be effectively scraped off.

[0060] Example 2:

[0061] Combine Figures 3 to 5 As shown, on the basis of Example 1, the longitudinal angle adjustment mechanism 100 further includes a vertical rail 170 mounted on the top of the base 110, a slider 180 movably mounted inside the vertical rail 170, a screw sleeve 190 arranged inside the slider 180, a progressive screw rod 160 arranged inside the vertical rail 170 and extending through the outside of the screw sleeve 190, two groups of first clamps 120 mounted on the vertical rail 170, a chassis 130 mounted inside the two groups of first clamps 120, a motor 140 arranged in the chassis 130, a transmission gear plate 150 mounted on the transmission shaft in the motor 140, a first guide rod 1901 mounted on the outer end of the screw sleeve 190, a pressure plate 1902 arranged outside the first guide rod 1901, two second guide rods 1903 mounted on the top and bottom of the pressure plate 1902, and two supporting plates 1904 mounted on the two second guide rods 1903;

[0062] The transmission gear plate 150 is adapted to mesh with the gear at the top of the progressive screw rod 160;

[0063] The other end of the support plate 1904 is movably mounted on the third guide rod 210 .

[0064] Preferably, two holes are opened inside the base 110, and the holes are fixed to the platform of the conveying path by bolts. In the initial state, the anti-skid mechanism 200 supported by the base 110 remains parallel to the existing steel conveying system;

[0065] When the motor 140 is powered on and running, the transmission shaft in the motor 140 rotates forward and cooperates with the transmission gear plate 150 to drive the progressive screw 160 to rotate reversely, and the screw sleeve 190 and the slider 180 will descend at a uniform speed along the threaded section of the progressive screw 160;

[0066] When the transmission shaft in the motor 140 rotates reversely and cooperates with the transmission gear plate 150 to drive the progressive screw 160 to rotate forward, the screw sleeve 190 and the slider 180 will rise at a uniform speed along the threaded section of the progressive screw 160;

[0067] When the slider 180 rises, the ports of the two supporting plates 1904 away from the pressure plate 1902 will face downward, and when the slider 180 falls, the ports of the two supporting plates 1904 away from the pressure plate 1902 will face upward.

[0068] Example 3:

[0069] Combine Figures 4 to 7 As shown, based on Example 1, the anti-sideslip mechanism 200 further includes two third guide rods 210 arranged at the top and bottom of the beam plate 220, four end rods 260 fixedly mounted on the beam plate 220, and guard plates 270 fixedly mounted on the outer ends of the four end rods 260, and the guard plates 270 are used to provide anti-slip protection for the tilted steel section;

[0070] A groove 240 is formed inside the beam plate 220;

[0071] The guard plate 270 is an oval structure as a whole, and a smooth coating is provided on the side of the guard plate 270 facing the steel section to reduce the friction resistance to the steel section that accidentally falls off.

[0072] Preferably, the pad 250 is fixed to the middle of the bottom surface of the beam plate 220 by welding, and the four end rods 260 are welded to the beam plate 220. The length of the four end rods 260 is the same as that of the shaft rod 410. The guard plate 270 is located outside the frustum-shaped end of the shaft rod 410.

[0073] As the chain 500 is driven by the external driving device, the chain 500 will drive multiple linkage gears 420, and the shaft 410 as a whole will rotate at a uniform speed. Finally, the shaft 410 and the four pipe segments 440 can rotate stably inside the guard plate 270.

[0074] Example 4:

[0075] Combine Figure 4 and Figure 5As shown, in the above embodiment, the guide energy supply mechanism 300 includes two sets of second clamps 310 installed on the beam plate 220, hydraulic components 320 installed inside the two sets of second clamps 310, a clamp 330 installed on the hydraulic sub-rod inside the hydraulic components 320, a vertical rod 340 movably installed inside the groove 240, a tripod 350 installed outside the vertical rod 340, the clamp 330 movably installed at one end of the tripod 350, a pull rod 360 movably installed at the other end of the tripod 350, and a traction member 370 installed at the other end of the pull rod 360;

[0076] The length of the end of the tripod 350 facing the chuck 330 is one third of the length of the end thereof close to the pull rod 360;

[0077] The traction member 370 is welded from two cross bars and three ring buckles, and the ring buckles are movably mounted on the shaft sleeve 460 .

[0078] Preferably, the two cross bars in the traction member 370 are respectively located in the middle of the two end bars 260. As the hydraulic member 320 operates until the internal hydraulic sub-bars thereof extend outward, the clamp 330 installed at the outer end of the hydraulic sub-bar will push the tripod 350 to turn outward with the vertical bar 340 as the center, and the end of the tripod 350 away from the clamp 330 will pull the pull rod 360 and the traction member 370 toward the beam plate 220.

[0079] When the hydraulic sub-rod in the hydraulic part 320 contracts, the clamp 330 installed at the outer end of the hydraulic sub-rod will pull the tripod 350 to turn inward with the tripod 350 as the center, and the other end of the tripod 350 will push the pull rod 360 and the pulling part 370 toward the guard plate 270.

[0080] The working principle and usage process of the present invention are as follows: the device is added to the path of steel conveying, and the longitudinal angle adjustment mechanism 100 is fixed to the port where the steel needs to be guided. As the independent chain 500 drives multiple linkage gears 420, the linkage gears 420 will drive the shaft 410 to rotate, and the four pipe segments 440 welded through the head 450 will drive the four sets of side feeding assemblies 480 to rotate at a uniform speed. In the initial state, the multiple sets of steel guide mechanisms 400 can provide an effective driving platform for the lateral movement of the steel.

[0081] When the steel sections passing through the multiple sets of steel section guide mechanisms 400 need to be guided and transferred upward or downward along a constant horizontal plane;

[0082] The motor 140 is run in advance. As the internal transmission shaft of the motor 140 cooperates with the transmission gear plate 150 to drive the progressive screw 160 to rotate at a uniform speed, the slider 180 and the screw sleeve 190 movably installed inside the vertical rail 170 will rise or fall at a uniform speed along the threaded section of the progressive screw 160. When the progressive screw 160 rotates forward, the slider 180 will cooperate with the first guide rod 1901 to push the pressure plate 1902 to rise as a whole. At this time, the beam 220 and the pad 250 will flip downward with the top of the base 110 as the flipping axis, and the steel guide mechanism 400 installed in the beam 220 through the bearing 230 can tilt downward, and the steel on the multiple sets of steel guide mechanisms 400 can be moved to a platform below the conveying system. Transfer, because the weight of the steel section itself will increase the resistance to its lateral transfer, so after the multiple sets of steel section guide mechanisms 400 are tilted downward, the hydraulic component 320 can be operated. As the hydraulic sub-rod in the hydraulic component 320 contracts inward, the clamp 330 set at the outer end of the hydraulic sub-rod will push the other end of the tripod 350 to extend outward, and finally the tripod 350 will push the pull rod 360, the traction member 370 and the multiple shaft sleeves 460 to move laterally along the shaft 410, and the shaft sleeves 460 will push the truss 470 to extend along the inner side of the four pipe segments 440, and finally the truss 470 will push the multiple sets of side feeding assemblies 480 to move laterally outward along the four pipe segments 440, and then the steel sections carried by the multiple sets of side feeding assemblies 480 can be effectively pushed out;

[0083] When the steel section needs to be pushed to a higher platform on the conveying platform, the reversal of the progressive screw 160 will help the slider 180 and the screw sleeve 190 to descend, and finally the pressure plate 1902 cooperates with the second guide rod 1903 and the support plate 1904 to push the anti-skid mechanism 200 to tilt upward as a whole. The multiple groups of steel section guide mechanisms 400 supported by the anti-skid mechanism 200 can tilt upward, and finally, in conjunction with the operation of the hydraulic parts 320, the multiple groups of side feeding assemblies 480 will push horizontally toward the head 450. As the side feeding assembly 480 moves horizontally as a whole, the evenly distributed multiple pressure plates 4808 will tilt along the outer walls of the four pipe segments 440, and finally can provide anti-skid protection for the upward pushing of the steel section.

[0084] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
