[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0030] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0032] In one embodiment, see Figure 1 , a rod mill steel bar vertical elevator is provided, comprising a discharge frame 11, a turnover platform 12 and a lifting frame 13; the discharge frame 11 is connected to the lifting frame 13 through the turnover platform 12; the discharge frame 11 comprises a lifting base 21, a steering bracket 22 arranged on the lifting base 21 and a loader frame 23 installed on the steering bracket 22; the turnover platform 12 comprises a turnover bracket 24 and a guide table 25 installed on the turnover bracket 24, the loader frame 23 is connected to the guide table 25, and the other end of the guide table 25 is provided with a feeding hook 26;

[0033] The lifting frame 13 includes a supporting frame 31, a chain transmission unit 32 arranged on the supporting frame 31, and a lifting bracket 33 installed on the supporting frame 31. The chain transmission unit 32 drives the lifting bracket 33 to reciprocate up and down along the supporting frame 31. A docking hook 36 is installed on the lifting bracket 33, and the docking hook 36 is connected to the feeding hook 26. A transition plate 34 is arranged on the top of the supporting frame 31, and a conveying mechanism 35 is externally connected to the transition plate 34.

[0034] This embodiment is used for lifting and processing of steel bars. The steel bars are discharged from the discharge rack 11 and introduced into the turnover platform 12 one by one. The turnover platform 12 is connected to the lifting rack 13, and then the lifting rack 13 is lifted and transported to a high place. The turnover platform 12 is a turnover interval, and the guide table 25 is designed to be inclined. The steel bars slide into the feeding hook 26, and then fall from the feeding hook 26 to the corresponding docking hook 36. The lifting rack 13 uses the supporting rack 31 as the supporting body, and the chain transmission unit 32 as the driving component to drive the lifting bracket 33 to move up and down along the supporting rack 31, and then gradually lift the steel bars to the transition plate 34 at a high place. The transition plate 34 is also designed to be inclined, and the steel bars are introduced into the conveying mechanism 35 for subsequent processing and use in the rod mill.

[0035] Since the length, material and weight of steel bars are different, if the steel bars are directly suspended and scattered on the guide table 25, they will inevitably collide with the guide table 25, causing the steel bars to vibrate, which not only affects the quality of the steel bars themselves, but also may cause the feeding hook 26 and the docking hook 36 to be unable to dock smoothly. Therefore, the discharge frame 11 of this embodiment is designed as a feeding structure for the steel bars, the lifting base 21 adjusts the support height, and the steering bracket 22 adjusts the angle of the loader frame 23 relative to the guide table 25. The steel bars are arranged in the loader frame 23 and slide onto the guide table 25 at a suitable angle, so that the steel bars can roll smoothly along the guide table 25, avoiding fluctuations during movement, ensuring the quality of the steel bars themselves, and facilitating the smooth docking of the turnover platform 12 and the lifting frame 13.

[0036] In one embodiment, see Figure 1 and Figure 2 For the specific implementation structure of vertical lifting of steel bars, this embodiment is designed as follows:

[0037] The supporting frame 31 includes a fixed frame 44 and a lifting track frame 40 arranged on both sides of the fixed frame 44; the chain transmission unit 32 includes a lifting cylinder 43 mounted on the bottom of the fixed frame 44, a connecting head 45 arranged on the top of the lifting cylinder 43 and a supporting shaft 46 installed on the connecting head 45, and sprockets 47 are installed at both ends of the support shaft 46; the main body of the lifting bracket 33 is a movable frame 49, and a wheel frame 41 and a transmission gear 48 installed on the wheel frame 41 are arranged in the inner frame of the movable frame 49, and the transmission gear 48 is connected to the sprocket 47 by a chain 42, and a walking assembly 50 is arranged on the side edge of the lifting bracket 33, and the walking assembly 50 is installed in the lifting track frame 40 on the corresponding side.

[0038] The steel rod to be transported slides from the guide table 25 to the docking hook 36. The lifting cylinder 43 is a power tool fixed on the bottom plane of the fixed frame 44. The head of the lifting cylinder 43 is equipped with a connector 45, which is fixed to the support shaft 46. The sprocket 47 is connected to the support shaft 46 by a bearing, and the sprocket 47 can rotate with the support shaft 46. The chain 42 cooperates with the sprocket 47. One end of the chain 42 is fixedly connected to the fixed frame 44, and the other end is fixedly connected to the movable frame 49. The walking assembly 50 is installed in the lifting track frame 40 on the corresponding side to form a rolling fit to achieve up and down movement. During the movement, for every 1mm rise of the rod of the lifting cylinder 43, the chain 42 drives the fixed end of the movable frame 49 to rise by 2mm, that is, the movable frame 49 rises by 2mm, realizing the doubling of the lift. In this form, the stroke of the lifting cylinder 43 is only half of the stroke required for the steel rod, realizing the miniaturization of the mechanism. The docking hook 36 is hingedly mounted on the movable frame 49 to avoid the other steel bars on the guide table 25 during the return journey. After passing the other steel bars on the guide table 25, the docking hook 36 returns to the initial state due to gravity. When the docking hook 36 reaches the top of the fixed frame 44, the steel bars slide down the inclined surface to the transition plate 34 due to gravity, and slide down along the inclined surface of the transition plate 34 to the conveying member 35, and then are transported to the rod mill along the conveying member 35.

[0039] In one case of this embodiment, see Figure 2 and Figure 3The lifting track frame 40 includes an outer track plate 57 arranged on the outside of the frame and an inner track plate 58 arranged on the inner edge of the frame; the walking component 50 includes an outer bracket plate 51 arranged on the outer frame surface of the movable frame 49, a plurality of outer support shafts 53 installed on the outer bracket plate 51 and side rollers 52 installed on the outer support shafts 53, and the side rollers 52 are all connected to the outer track plate 57; the walking component 50 also includes a plurality of inner base blocks 54 arranged on the frame plate of the movable frame 49, an inner support 55 installed on the inner base block 54 and an inner roller 56 installed on the inner support 55, and the inner roller 56 is embedded in the inner track plate 58.

[0040] The steel rod is supported on the movable frame 49 by the docking hook 36. In order to improve the stability of the steel rod lifting, the present embodiment is respectively provided with an outer track plate 57 and an inner track plate 58 on the lifting track frame 40. The outer track plate 57 and the inner track plate 58 are arranged vertically in space. The walking component 50 is also correspondingly provided with side rollers 52 and inner rollers 56, which form a stable structure of inner and outer interlocking, thereby forming a mutually perpendicular double limit track, reducing the vibration influence of the cylinder drive and the chain drive, thereby ensuring the stability of the steel rod lifting.

[0041] In one case of this embodiment, see Figure 1 and Figure 4 As for the implementation structure of the conveying mechanism 35, the conveying mechanism 35 of this embodiment includes a support bearing 61, a drive shaft 62 installed on the support bearing 61, and a conveyor barrel 63 installed on the drive shaft 62, and the barrel body of the conveyor barrel 63 forms an arc-shaped concave surface 64. There are multiple conveyor barrels 63, which are arranged along the path from the lifting frame 13 to the rod mill. As the conveyor barrel 63 rotates, it is input into the rod mill from the arc-shaped concave surface 64. As an example, the conveying mechanism 35 in the figure is only used for orientation indication. The conveying mechanism 35 can be erected on the top of the support frame 31, or it can be independently installed using a bracket, which can be set according to actual needs. The side edge of the conveyor barrel 63 is also provided with a limit plate 65 to prevent the steel rod from deflecting.

[0042] In one case of this embodiment, see Figure 1 and Figure 5 , Figure 6 The docking hook 36 and the feeding hook 26 both include a hook 66 and welding plates 67 arranged on both sides of the hook 66 , and the hook 66 is installed on the welding plate 67 through a resettable hinge bolt 68 .

[0043] The docking hook 36 and the feeding hook 26 of the present invention are both designed to be hinged and installed, and are designed to be resettable lifting hooks. During the rising process, the steel bar can fall on the hook 66 and rise together with the movable frame 49 with the hook 66. During the return process, the hinged hook 66 will be lifted up when passing through the steel bar, and after passing through the steel bar, it will return to its initial position under the action of gravity, meeting the needs of reciprocating travel.

[0044] In one embodiment, see Figure 7 and Figure 8 As for the specific implementation structure of steel bar discharge, this embodiment is designed as follows:

[0045] The lifting base 21 is a lifting adjustment device, which can adjust the support height according to the guide table 25; the steering bracket 22 includes an upper bracket plate 71, a steering support frame 72 installed on the upper bracket plate 71, and an adjustment bracket 73 installed on the steering support frame 72, the loader frame 23 is installed on the adjustment bracket 73, and the upper bracket plate 71 is installed on the top of the lifting base 21; a positioning sleeve 75 is provided on the frame wall of the steering support frame 72, and a steering support shaft 74 is provided between the positioning sleeves 75, the bottom end of the adjustment bracket 73 is mounted on the steering support shaft 74, and an arc track 76 is provided on the frame wall of the steering support frame 72, and the side limit of the adjustment bracket 73 is located in the arc track 76.

The loader frame 23 is mounted on the adjustment bracket 73. The adjustment bracket 73 is installed in the inner frame space of the steering support frame 72 and can rotate relative to the steering support frame 72 with the steering support shaft 74 as the axis, so as to adjust the angle of the loader frame 23 relative to the guide table 25, that is, to adjust the inclination angle of the steel bar sliding down. The arc track 76 limits the swing of the adjustment bracket 73 to improve the stability during adjustment.

[0047] The loader frame 23 includes a main mounting frame 81 and a positioning frame plate 82 disposed on the inner edge of the main mounting frame 81, the positioning frame plate 82 is fixedly mounted on the inner frame surface of the adjustment bracket 73, and the main mounting frame 81 includes a loading frame plate 83 and position limiting side rails 84 disposed on both sides of the loading frame plate 83.
