Technical Field

[0001] The present invention relates to the technical field of steel section conveying, and particularly to a steering mechanism for steel section conveying of an AGV forklift mast. Background Art

[0002] The steel sections of the forklift mast are mainly used for the inner and outer masts of the lifting part of the forklift, and are mainly made of hot-rolled steel sections, with 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 conveying of steel section materials is mainly driven by conveying rollers. Due to the heavy weight of the steel section itself, during the transfer on the conveying rollers, the frictional resistance at the contact surface between the steel section and the conveying rollers is extremely large. When the steel section needs to be laterally transferred, the conveying rollers are likely to cause wear or scratches on the bottom surface of the steel section placement. At the same time, as the steel section continuously contacts the surface of the conveying rollers, impurities on the surface of the steel section will accumulate on the surface of the conveying rollers, and in severe cases, it will cause an increase in the degree of corrosion of the conveying rollers.

The longitudinal angle adjustment mechanism 100 is used to adjust the inclination angle of the anti-side slip mechanism 200. The anti-side slip mechanism 200 is used to provide effective support for multiple groups of section steel guiding mechanisms 400. The guiding and energy supply mechanism 300 cooperates with multiple groups of section steel guiding mechanisms 400 to laterally deliver the inclined section steel.

[0025] The longitudinal angle adjustment mechanism 100 includes a base 110; The anti-side slip mechanism 200 includes a backing plate 250 movably installed at the top of the base 110, a beam plate 220 installed on the top of the backing plate 250, and a bearing 230 provided in the internal hole of the beam plate 220; The section steel guiding mechanism 400 includes a shaft rod 410 provided in the bearing 230, a linkage gear 420 provided on the shaft rod 410, and two limiting holes 430 are opened in the frustum-shaped end face of the shaft rod 410. Four pipe segments 440 are installed at the outer end of the shaft rod 410, a head 450 is installed at the outer end of the four pipe segments 440, multiple groups of lateral feeding assemblies 480 are provided inside the four pipe segments 440, and two trusses 470 are provided on the multiple groups of lateral feeding assemblies 480; The lateral feeding assembly 480 is used to provide anti-detachment protection for the inclined section steel; The lateral feeding assembly 480 includes an inner gasket 4801 movably installed inside the four pipe segments 440, a third chuck 4806 movably installed inside the inner gasket 4801, a spring 4807 provided outside the third chuck 4806 and pressing on the inner gasket 4801, four first chucks 4802 fixedly installed on one side of the inner gasket 4801, an inclined frame 4803 movably installed at the outer end of the first chuck 4802, a second chuck 4804 movably installed at the other end of the inclined frame 4803, a slip ring 4805 movably installed outside the four pipe segments 440, and a fourth chuck 48061 installed on the slip ring 4805; Four limiting grooves 4809 are opened on the inner wall of the slip ring 4805, and the connection end of the inclined frame 4803 and the second chuck 4804 is located in the limiting groove 4809; The other end of the second chuck 4804 and the other end of the fourth chuck 48061 are movably installed with pressing plates 4808; Both ends of the pressing plate 4808 are provided with outward-slanting bevels, and after the pressing plate 4808 is tilted, the ports of the outward-slanting bevels are used to scrape the caked dirt on the second chuck 4804; A transverse groove is provided inside the truss 470; Both sides of the built-in gasket 4801 are provided with fan-shaped notches, and the truss 470 is installed in the fan-shaped notches.

[0026] When the beam slab 220 cooperates with the backing plate 250 and is laterally overturned along the top end of the base 110, the entire steel guide mechanism 400 that is assembled in the beam slab 220 by the bearing 230 and is horizontally placed can be tilted and adjusted. As the inclination angles of multiple groups of steel guide mechanisms 400 are adjusted, the truss 470 will push multiple built-in gaskets 4801 to move horizontally along the inner sides of the four segments 440. At the same time, the four first chucks 4802 installed on the built-in gaskets 4801 will push the inclined frame 4803 and the second chuck 4804 to extend until the truss 470 exerts pressure on two of the inclined frames 4803 in one set of lateral feeding components 480. At this time, the four segments 440 will exert a reverse resistance on the built-in gasket 4801. At this time, the end of the pressing plate 4808 facing the steel will tilt towards the segment 440, and the tilted pressing plate 4808 can provide effective support and anti-disengagement protection for the steel. Finally, the delivered steel can be safely transferred onto the selected conveying platform; During the horizontal movement of the slip ring 4805, the dirt accumulated outside the four segments 440 can be effectively scraped off.

[0027] Embodiment 2: Combined Figures 3 to 5 As shown, on the basis of Embodiment 1, the longitudinal angle adjustment mechanism 100 further includes a vertical rail 170 installed on the top of the base 110, a slider 180 movably installed inside the vertical rail 170, a screw sleeve 190 provided inside the slider 180, a progressive lead screw 160 provided inside the vertical rail 170 and penetrating outside the screw sleeve 190, two sets of first clamps 120 installed on the vertical rail 170, a chassis 130 installed inside the two sets of first clamps 120, a motor 140 provided inside the chassis 130, a transmission gear disk 150 installed on the transmission shaft of the motor 140, a first guide rod 1901 installed at the outer end of the screw sleeve 190, a bearing plate 1902 provided outside the first guide rod 1901, two second guide rods 1903 installed on the top and bottom of the bearing plate 1902, and two support plates 1904 installed on the two second guide rods 1903; The transmission gear disk 150 is adaptively meshed with the gear at the top end of the progressive lead screw 160; The other end of the support plate 1904 is movably installed on the third guide rod 210.

[0028] Preferably, two through holes are formed inside the base 110, and the through holes are fixed to the platform of the conveying path by bolts. In the initial state, the anti-slip mechanism 200 supported by the base 110 is parallel to the existing profiled steel conveying system. After the motor 140 is powered on and operates, when the transmission shaft in the motor 140 rotates forward and cooperates with the transmission gear disk 150 to drive the progressive lead screw 160 to rotate reversely, the screw sleeve 190 and the slider 180 will descend uniformly along the threaded section of the progressive lead screw 160. When the transmission shaft in the motor 140 rotates reversely and cooperates with the transmission gear disk 150 to drive the progressive lead screw 160 to rotate forward, the screw sleeve 190 and the slider 180 will rise uniformly along the threaded section of the progressive lead screw 160. After the slider 180 rises, the ports of the two supporting plates 1904 away from the bearing plate 1902 will face downward. After the slider 180 descends, the ports of the two supporting plates 1904 away from each other will face upward.

[0029] Embodiment 3: Combined with Figures 4 to 7 As shown in the figure, on the basis of Embodiment 1, the anti-slip mechanism 200 further includes two third guide rods 210 arranged on the top and bottom of the beam plate 220, four end rods 260 fixedly installed on the beam plate 220, and a guard plate 270 fixedly installed at the outer ends of the four end rods 260. The guard plate 270 is used to provide anti-disengagement protection for the tilted profiled steel. A groove 240 is formed inside the beam plate 220. The guard plate 270 is integrally in an oval structure, and a smooth coating is provided on the side of the guard plate 270 facing the profiled steel, which is used to reduce the frictional resistance to the accidentally disengaged profiled steel.

[0030] Preferably, the cushion plate 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 lengths of the four end rods 260 are the same as the length of the shaft rod 410. The guard plate 270 is located outside the frustum-shaped end of the shaft rod 410. After the chain 500 is driven by an external driving device, the chain 500 will drive a plurality of linkage gears 420, and the whole shaft rod 410 will rotate uniformly. Finally, the shaft rod 410 and the four segments 440 can rotate stably inside the guard plate 270.

[0031] Embodiment 4: Combined with Figure 4 and Figure 5As shown in the above embodiment, the guiding and energy supply mechanism 300 includes two groups of second clamps 310 installed on the beam plate 220, a hydraulic component 320 installed inside the two groups of second clamps 310, a chuck 330 installed on the hydraulic sub-rod inside the hydraulic component 320, a vertical rod 340 movably installed inside the groove 240, a tripod 350 installed outside the vertical rod 340, and the chuck 330 is 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; The length of the end of the tripod 350 facing the chuck 330 is one-third of the length of the end close to the pull rod 360; The traction member 370 is formed by welding two cross bars and three loop fasteners, and the loop fasteners are movably installed on the bushing 460.

[0032] 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 component 320 operates, until the hydraulic sub-rod inside it extends outwards, the chuck 330 installed at the outer end of the hydraulic sub-rod will push the tripod 350 to turn outwards with the vertical rod 340 as the center, and the end of the tripod 350 far from the chuck 330 will pull the pull rod 360 and the traction member 370 towards the beam plate 220; When the hydraulic sub-rod in the hydraulic component 320 contracts, the chuck 330 installed at the outer end of the hydraulic sub-rod will pull the tripod 350 to turn inwards with the tripod 350 as the center, and the other end of the tripod 350 will push the pull rod 360 and the traction member 370 towards the guard plate 270.

[0033] The working principle and usage process of the present invention: Add this device on the path of steel section conveying. By fixing the longitudinal angle adjustment mechanism 100 at the port part where the steel needs to be guided, as the independent chain 500 drives multiple linkage gears 420, at this time, the linkage gears 420 will drive the shaft rod 410 to rotate, and the four pipe pieces 440 welded by the end cap 450 will drive the four groups of lateral feeding components 480 to rotate at a constant speed. The multiple groups of steel section guiding mechanisms 400 in the initial state can provide an effective transverse movement pushing platform for the steel section; When the steel sections passing through the multiple groups of steel section guiding mechanisms 400 need to be guided and transferred, and transferred upwards or downwards along a constant horizontal plane; Pre-run the motor 140. As the internal transmission shaft of the motor 140 cooperates with the transmission gear disc 150 to drive the progressive lead screw 160 to rotate at a constant speed, the slider 180 and the nut sleeve 190 movably installed inside the vertical rail 170 will rise or fall at a constant speed along the threaded section of the progressive lead screw 160. When the progressive lead screw 160 rotates forward, the slider 180 will cooperate with the first guide rod 1901 to push the bearing plate 1902 to rise as a whole. At this time, the beam plate 220 and the cushion plate 250 will take the top end of the base 110 as the axis of rotation and turn downward. The profiled steel guiding mechanism 400 installed in the beam plate 220 through the bearing 230 can be tilted downward, and the profiled steel on multiple profiled steel guiding mechanisms 400 can be transferred to a platform lower than the conveying system. Since the self-weight of the profiled steel will increase the resistance of its lateral transfer, after multiple profiled steel guiding 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 chuck 330 arranged at the outer end of the hydraulic sub-rod will push the other end of the tripod 350 to extend outward. Finally, the tripod 350 will push the pull rod 360, the traction member 370 and multiple bushings 460 to move horizontally along the shaft rod 410, and the bushing 460 will push the truss 470 to extend along the inner sides of the four segments 440. Finally, the truss 470 will push multiple lateral feeding assemblies 480 to move horizontally outward along the four segments 440, and then the profiled steel carried by multiple lateral feeding assemblies 480 can be effectively pushed out; When the profiled steel needs to be pushed onto a conveying platform of a higher platform, the reverse rotation of the progressive lead screw 160 will boost the descent of the slider 180 and the nut sleeve 190. Finally, the bearing plate 1902 will cooperate with the second guide rod 1903 and the support plate 1904 to push the anti-side-slip mechanism 200 to tilt upward as a whole. Multiple profiled steel guiding mechanisms 400 supported by the anti-side-slip mechanism 200 can be tilted upward. Finally, in cooperation with the operation of the hydraulic component 320, multiple lateral feeding assemblies 480 will push horizontally towards the head 450. As the lateral feeding assemblies 480 move horizontally as a whole, the uniformly distributed multiple pressing pieces 4808 will tilt along the outer walls of the four segments 440. Finally, anti-slip protection can be provided for the upward progressive push of the profiled steel.
