Description

TECHNICAL FIELD

[0002] Profile steel is a strip-shaped steel material with a certain cross-sectional shape and size, and the profile steel used for the forklift mast has a rectangular cross-section, which is made by hot rolling, cold drawing and other processing technologies.

[0003] At present, during the production of the forklift mast profile steel, the profile steel after hot rolling needs to be transferred to the next link by using conveying equipment. The existing conveying equipment uses conveying rollers to convey the steel material. However, the bearing area of the existing conveying roller is large, so the steel material will be inclined at a certain angle during conveying on the conveying roller. Once the steel material needs to be diverging guided, the inclined steel material on the starting conveying system will increase the change of the inclination angle after being transferred to the next conveying system due to the angle inclination and external interference, thereby causing a large difference in the position of the steel material on the next link conveying equipment.

[0026] When the section steel is conveyed by the conveying device, after the section steel enters the gap between the eight secondary roller sleeves 4802 and the eight main roller sleeves 4703, the U-shaped gap formed by the eight main roller sleeves 4703 and the eight secondary roller sleeves 4802 can adaptively clamp the steel, so that the steel can be effectively constrained before being guided in different directions. The motor 160 is started, the inner transmission shaft of the motor 160 drives the chain 180 through the first gear 170, the chain 180 drives the second gear 220 and the supporting column 210, finally the supporting column 210 and the fixed lifting slide 260 rotate along the top of the bottom rail 130, at this time the lifting slide 260 rotates along the top of the bottom rail 130 and rises, when the lifting slide 260 rotates by 90 degrees, the load plate 240 supported by the supporting column 210 rotates and rises, finally the overturned section steel can be transferred to the next conveying platform, after the section steel is guided in different directions, the load plate 240 adjusts the inclination angle along the first guide rod 230, the clamped section steel can be accurately placed on the next conveying device, so that the angle difference of the section steel after transfer is avoided.

[0027] Embodiment 2: In combination Figures 2 to 5 As shown in the figure, on the basis of Embodiment 1, the fixed-point transposition mechanism 200 further comprises a main clamp 250 and a sub-clamp 2501, and the top end of the lifting slide 260 is provided with a horizontal groove, and the sub-clamp 2501 is fixedly installed on the inner wall of the horizontal groove; The first hydraulic component 2502 is movably installed between the sub-clamp 2501 and the main clamp 250; The fixed-point transposition mechanism 200 further comprises two groups of clamps 270 fixedly installed on the top of the bearing plate 240, a second hydraulic component 280 installed in the two groups of clamps 270, an end 2801 installed on the hydraulic sub-rod of the second hydraulic component 280, a second guide rod 290 arranged in the bearing plate 240, and a turnover bracket 2802 movably installed on the outside of the second guide rod 290; One end of the turnover bracket 2802 is movably installed on the end 2801.

[0028] The second gear 220 is installed at the bottom end of the support column 210, and the other end of the chain 180 is drivingly connected to the second gear 220; The outer wall of the lifting slide 260 is provided with a ring groove, and the outer side of the top of the bottom rail 130 is provided with an arc groove, and the other end of the clamp 150 is movably installed in the ring groove and the arc groove.

[0029] After the second gear 220 is driven, the combined second gear 220 and support column 210 will rotate at a constant speed along the base 120, and the lifting slide 260 will rotate and lift along the top of the bottom rail 130. After the first hydraulic component 2502 operates, the hydraulic sub-rod inside it extends outward to push the main clamp 250 upward, and the end of the bearing plate 240 away from the main clamp 250 will approach the cross beam 110 and tilt; When the hydraulic sub-rod in the first hydraulic component 2502 retracts, the end of the bearing plate 240 pulled towards the main clamp 250 will stretch towards the cross beam 110. This process can selectively deliver the clamped steel to the next conveying equipment; When the lifting slide 260 rotates and rises, the support column 210 and the second gear 220 also rise, and at the same time, the clamp 150 movably installed in the ring groove of the outer wall of the lifting slide 260 also drives the case 140 and the motor 160 to rise synchronously, thereby ensuring that the chain 180 maintains effective driving connection with the first gear 170 and the second gear 220.

[0030] Embodiment 3: In combination Figures 6 to 8As shown, on the basis of embodiment 1, the section steel width adapting mechanism 300 comprises two bases 310 arranged on the top of the bearing plate 240 and two positioning bolts 380 arranged in the bases 310, the inside of the base 310 is provided with a sliding groove 320, and the sliding groove 320 is provided with a truss 330, a pad 340 arranged on the bottom of the truss 330 and four lock buckles 350 arranged on the truss 330; The section steel width adapting mechanism 300 further comprises eight inclined frames 360, two inclined frames 360 form a group, four groups of inclined frames 360 are connected to the four lock buckles 350 respectively, and the outer end of the inclined frame 360 is movably connected with an adapter 370.

[0031] Preferably, the lock buckle 350 is fixed on the truss 330 by a bolt, the inclined frame 360 is composed of two end rods and two end plates, one of the end rods is movably connected in the lock buckle 350, and the other end rod is movably connected in the adapter 370. When the inclined frame 360 is pressed to push the adapter 370, the adapter 370 controls the third guide rod 4701 and the whole sliding frame 470 to move horizontally along the slide 4101 until the adjacent two sliding frames 470 adaptively clamp the turned section steel, when the two sliding frames 470 stretch outwards, the lock head 450 limited by the gasket 430 and the traction frame 460 limit the leg 4803 and the shaft 480, at this time, the wider side of the section steel can be effectively supported by the main roller sleeve 4703 and the auxiliary roller sleeve 4802.

[0032] The working principle and use process of the present application are as follows: the cross beam 110 is fixedly installed on the section steel conveying platform by bolts, and the device cooperates with the conveying device to form a continuous feeding system. According to the size of the section steel, the second hydraulic part 280 is pre-operated, and when the hydraulic sub-rod in the second hydraulic part 280 stretches outwards, the end 2801 arranged at the outer end of the hydraulic sub-rod pushes the turnover support 2802 to turn over, the other end of the turnover support 2802 pushes the pad 340 and the truss 330 to lift upwards, at this time, the four lock buckles 350 arranged on the truss 330 exert outward expansion force on the plurality of inclined frames 360, and the sliding frame 470 connected to the adapter 370 stretches outwards along the slide 4101, at this time, the four groups of sliding frames 470 distributed symmetrically can adaptively adjust the wider section steel. When it is necessary to adapt the narrower section steel, only the second hydraulic part 280 needs to be operated until the internal hydraulic sub-rod is retracted. After the profiled steel enters the gap formed by the eight sub-roller sleeves 4802 and the eight main roller sleeves 4703, the profiled steel is limited and supported in the unpowered state. At this time, the motor 160 can be operated. When the transmission shaft in the motor 160 cooperates with the first gear 170 to drive the chain 180, the other end of the chain 180 drives the second gear 220 and the support column 210. The lifting slide 260 installed at the top of the support column 210 swings along the bottom rail 130. Finally, the lifting slide 260 is lifted upward along the track inside the bottom rail 130. At the same time, the case 140 fixed to the bottom rail 130 drives the motor 160, the first gear 170, and the chain 180 to rise at the same time. The lifting slide 260 after rising also lifts the load plate 240, the profiled steel width adjusting mechanism 300, and the assisting mechanism 400 upward. Finally, the load plate 240 forms a ninety-degree angle with the cross beam 110. The profiled steel clamped can be rotated and lifted from the initial position. After the profiled steel is rotated and lifted, according to the feeding requirements of the higher position conveying platform, the first hydraulic part 2502 can be operated to control the inclination of the load plate 240 along the top end of the support column 210 until the inclination angle of the load plate 240 can meet the natural sliding of the profiled steel. In addition, during the rotation and lifting of the profiled steel, the profiled steel clamped by the four sets of assisting mechanisms 400 can be discharged at multiple angles according to requirements. After the profiled steel is transferred, the support column 210 is continuously driven. The lifting slide 260 fixed at the top of the support column 210 rotates along the top of the bottom rail 130. Finally, the height of the load plate 240 returns to the initial state, thereby facilitating the subsequent wind direction guidance of the profiled steel.

[0033] Although the embodiments of the present application have been shown and described, those skilled in the art can understand that various changes, modifications, replacements, and variations can be made to these embodiments without departing from the principles and purposes of the present application.
