During the loading process, part of the rods 100 can be stored on the chain 2 514. When the straightening table 1 needs the rod 100 immediately, the chain 2 514 and the dividing mechanism 52 can be started to immediately separate the rod 100 from the chain 2 514, thereby solving the technical problems of low efficiency and large-scale consumption of manpower and material resources in the prior art of transferring the rods 100, realizing automatic loading and large-scale storage, and connecting the storage area with the straightening area, thereby improving production efficiency.

[0016] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0017] Reference Figure 1 , Figure 2 as well as Figure 3 A drill rod straightening device includes a straightening table 1, a straightening rod 2, a three-dimensional scanner 3, a material storage rack 4, and a feeder 5. The straightening table 1 is equipped with a plurality of equidistantly distributed top blocks 11, and a rod 100 is placed on the top blocks 11, and the top blocks 11 can lift the rod 100; a mobile rack is installed on the straightening table 1, and the straightening rod 2 can be installed on the mobile rack. The straightening rod 2 can be hydraulically controlled and press down on the rod 100, and the three-dimensional scanner 3 can also be installed on the mobile rack. The movement of the mobile rack can drive the movement of the three-dimensional scanner 3, and the three-dimensional scanner 3 can scan the rod 100. The precise data measured by the three-dimensional scanner 3 is used to adjust the straightening position. The two sides of the straightening table 1 can be equipped with clamping grips 12 that can move along the length direction of the straightening table 1, and the clamping grips 12 are used to clamp the rod 100. The loader 5 is located at the feeding end of the straightening table 1 , the storage rack 4 is located at one side of the loader 5 , the loader 5 is connected to the straightening table 1 , and the storage rack 4 is connected to the loader 5 .

[0018] Reference Figure 3 and Figure 4The storage rack 4 includes a support frame plate 41, a door frame 42, a sprocket set 1 43, a drive motor 1 44, a chain 1 45, a chain box 46, and a sprocket set 3 47. The support frame plate 41 is flat and can be laid flat on the ground. The bar 100 can be placed on the support frame plate 41. A lifting rack 411 is fixed on one side of the support frame plate 41 close to the feeder 5. The height of the lifting rack 411 is higher than that of the support frame plate 41, and the length of the lifting rack 411 is longer than that of the support frame plate 41. The height of the door frame 42 is higher than that of the support frame plate 41. The door frame 42 is fixed on one side of the support frame plate 41 away from the lifting rack 411. The lateral width of the door frame 42 is greater than the length of the bar 100. The sprocket set 1 43 can be composed of a sprocket plate and a sprocket. The sprocket set 1 43 is fixedly installed on the top of the lifting frame 411. There are multiple sprocket sets 43 and they are equidistantly arranged along the length direction of the lifting frame 411. The sprockets in each sprocket set 1 43 are connected by a shaft rod and rotate coaxially. The driving motor 1 44 is installed on the sprocket plate of the sprocket set 1 43 at one end. The driving motor 1 44 drives the shaft rod of the sprocket set 1 43 to rotate. The driving motor 1 44 can make the sprockets in each sprocket set 1 43 rotate synchronously. The chain box 46 is fixedly installed below the sprocket set 1 43. The chain box 46 is installed below each sprocket set 1 43. The sprocket set 3 47 can also be composed of a sprocket plate and a sprocket. The sprocket set 3 47 is fixedly installed on the top of the door frame frame 42. There are multiple sprocket sets 3 47 and they correspond to each sprocket set 1 43. One end of chain 1 45 is detachably connected to the sprocket of sprocket set 3 47 , and the other end is located in chain box 46 , and chain 1 45 matches the sprocket in sprocket set 1 43 , and chain 1 45 is arranged between each sprocket set 1 43 and sprocket set 3 47 .

[0019] Starting the drive motor 44 can drive the sprocket in the sprocket set 43 to rotate, and make the chain 45 recovered into the chain box 46, so that the chain 45 between the sprocket set 43 and the sprocket set 3 47 can be gradually straightened, and the sprocket in the sprocket set 43 can rotate in the opposite direction, so that the chain 45 can be gradually loosened. When it is necessary to store several bars 100 before straightening, untie one end of the chain 45 located at the sprocket set 3 47, use a grabbing device to grab the bars 100 and pass them through the door frame 42 to put them on the supporting frame plate 41, and then fix the end of the chain 45 on the sprocket set 3 47, so that the chain 45 is below the bars 100, and when the driving motor 44 is started, the chain 45 is gradually straightened. As the chain 45 is tightened, the bars 100 can be gradually lifted and moved to one side of the sprocket set 43 until they climb over the sprocket set 43 and enter the loader 5. After some of the bars 100 enter the loader 5, as the chain 45 relaxes, the bars 100 will be put back on the supporting frame plate 41. Therefore, the material storage rack 4 can seamlessly connect the grabbing device to discharge the bars 100, and there is no need to sort out the bars 100 placed on the ground after being grabbed by the grabbing device. The chain 45 can be tightened to place the bars 100 neatly.

[0020] Reference Figure 3 and Figure 5 The feeder 5 includes a receiving mechanism 51, a dividing mechanism 52 and a conveying mechanism 53. The receiving mechanism 51 is connected to the lifting frame 411, the conveying mechanism 53 is located between the receiving mechanism 51 and the straightening table 1, the dividing mechanism 52 is located above the receiving mechanism 51, the receiving mechanism 51 is used to receive and arrange the bars 100 removed from the chain 1 45, the dividing mechanism 52 is used to remove the bars 100 one by one to the conveying mechanism 53, and the conveying mechanism 53 is used to convey the bars 100 one by one to the straightening table 1.

[0021] Continue to refer to Figure 3 and Figure 5The material receiving mechanism 51 includes a horizontal frame plate 511, a sprocket set 512, a drive motor 513, and a chain 514. The horizontal frame plate 511 is a strip-shaped frame plate, and the length direction of the horizontal frame plate 511 is perpendicular to the length direction of the supporting frame plate 41. One end of the horizontal frame plate 511 is fixed on the lifting frame 411, and the other end is connected to the conveying mechanism 53. There are a plurality of horizontal frame plates 511 that are parallel to each other, and two horizontal frame plates 511 can form a pair, and two teams of horizontal frame plates 511 are respectively set at both ends of the supporting frame plate 41. The sprocket set 2 512 can be composed of a sprocket plate and a sprocket. The sprocket set 2 512 is fixedly mounted on the cross frame plate 511. A plurality of sprocket sets 2 512 are fixedly mounted on each cross frame plate 511. Each sprocket set 2 512 on each cross frame plate 511 is matched and connected by a chain 2 514. In addition, the sprockets in the sprocket set 2 512 at one end of each cross frame plate 511 are coaxially connected through an axle rod, and the drive motor 2 513 is used to drive the sprockets in the coaxially rotating sprocket set 2 512 to rotate. Therefore, the start of the drive motor 2 513 can drive each chain 2 514 to move synchronously. Therefore, when the bar 100 on the chain 1 45 passes over the sprocket set 1 43, it will enter the chain 2 514, and the movement of the chain 2 514 can make the bar 100 gradually move toward the conveying mechanism 53.

[0022] Reference Figure 3 As shown, the conveying mechanism 53 includes a material trough 531 and a conveyor belt 532. The length direction of the material trough 531 is consistent with the length direction of the straightening table 1. The top of the material trough 531 is open and one end facing the straightening table 1 is also open. The top of the material trough 531 is located below the end of the chain 2 514 in the material receiving mechanism 51 away from the material storage rack 4, and the material dividing mechanism 52 is located above the conveying mechanism 53. The material dividing mechanism 52 can separate the bars 100 on the chain 2 514 from the chain 2 514 one by one, and finally they will fall into the material trough 531.

[0023] Reference Figure 6 and Figure 7The material distribution mechanism 52 is fixedly installed on the side wall of the material trough 531. Two material distribution mechanisms 52 are provided, and are respectively located at the two ends of the material trough 531. The material distribution mechanism 52 includes a distribution frame 521, an electric telescopic cylinder 522, a horizontal plate 523, a distribution plate 524, a slide rail 501, and a slider 502; the distribution frame 521 is composed of plates, and the height of the distribution frame 521 is higher than the height of the second chain 514. The distribution frame 521 is fixedly installed on the side wall of the material trough 531 away from the second chain 514. A bracket 5211 is fixed on the side of the distribution frame 521 facing the second chain 514. The end of the bracket 5211 away from one end of the distribution frame 521 is located directly above the second chain 514. The bracket 5211 is in an L-shaped plate shape and is provided with two pieces. There is a distance between the two brackets 5211; the electric telescopic cylinder 522 is provided with a horizontal plate 523, and the horizontal plate 524 is provided with a horizontal plate 501, and the horizontal plate 502 ... The bottom of the cylinder 522 is rotatably set on the distribution rack 521, the telescopic rod 5221 of the electric telescopic cylinder 522 is located between the two brackets 5211, and the end of the telescopic rod 5221 away from the distribution rack 521 is located directly above the chain 2 514; the length direction of the cross plate 523 is perpendicular to the length direction of the rod 100, the middle part of the cross plate 523 is rotatably set in the two brackets 5211, and the length direction of the rotation axis is consistent with the length direction of the rod 100, and slots 5231 are provided at both ends of the length direction of the cross plate 523, and the end of the telescopic rod 5221 of the electric telescopic cylinder 522 is hinged to the top surface of the middle part of the cross plate 523. There are two dividing plates 524, which are respectively located below the slots 5231 at both ends of the horizontal strip 523. The length direction of the dividing plate 524 is consistent with the length direction of the rod 100, and the dividing plate 524 is in an upright state. The spacing between the two dividing plates 524 is the diameter of the rod 100. The slide rail 501 is vertically arranged, and the slide rail 501 is vertically fixed on the bracket 5211. A slider 502 is fixed to the inner wall of the dividing plate 524, and the slider 502 is slidably connected to the slide rail 501, so the dividing plate 524 moves vertically. An insertion rod 5241 is arranged on the top of the dividing plate 524, and the insertion rod 5241 is inserted into the slot 5231 at the end of the horizontal strip 523, and the insertion rod 5241 is connected to the top of the dividing plate 524 by a fixing strip.

[0024] The extension and retraction of the telescopic rod 5221 in the electric telescopic cylinder 522 can drive the horizontal strip 523 to swing left and right. When the horizontal strip 523 swings left and right, the insertion rod 5241 in the slot 5231 of the horizontal strip 523 moves in the slot 5231, and at this time, the vertical movement directions of the dividing plates 524 on both sides are opposite and the speed is consistent. Therefore, when the dividing plate 524 on the side away from the material trough 531 moves downward, the dividing plate 524 on the side close to the material trough 531 moves upward. At this time, the dividing plate 524 on the side away from the material trough 531 will be inserted between the two rods 100, and because the dividing plate 524 on the side close to the material trough 531 is in an upward state, The rod 100 will enter the material trough 531, while the other rods 100 will be blocked by the dividing plate 524 on the side away from the material trough 531, preventing them from entering the material trough 531. Later, when it is necessary to feed the material trough 531 again, the dividing plate 524 on the side away from the material trough 531 will be moved upward, and the dividing plate 524 on the side close to the material trough 531 will be moved downward. Under the movement of the chain 2 514, the rod 100 will reach the dividing plate 524 on the side close to the material trough 531, and then when the dividing plate 524 on the side away from the material trough 531 is moved downward, the dividing plate 524 on the side close to the material trough 531 will be moved upward, so that one rod 100 can be sent to the material trough 531.

[0025] The present invention can be explained by the following operation mode: During the straightening process of the drill rod, each time a bar 100 is straightened, the straightening table 1 needs to be loaded with the bar 100 again. The present invention integrates the storage and loading of the bar 100. The storage process is to use a grabbing device to grab multiple bars 100 on the material cart, and then the grabbing device puts the bars 100 through the door frame 42 and puts them on the support frame plate 41, and starts the drive motor 44. With the tension of the chain 45, each bar 100 can be made neat, without the need for the grabbing device to put the bars 100 on the ground after grabbing them, and then the production staff will put the bars 100 on the ground neatly one by one on the support frame plate 41. The feeding process is to start the driving motor 44, gradually straighten the chain 45, and as the chain 45 is tightened, the rod 100 can be gradually lifted and moved to one side of the sprocket set 43, and part of the rod 100 will climb over the sprocket set 43 and enter the chain 2 514. The movement of the chain 2 514 can gradually move the rod 100 toward the conveying mechanism 53, and then use the dividing mechanism 52 to divide the rods 100 into the trough 531 one by one, and the conveyor belt 532 in the trough 531 will carry the rods 100 to the conveyor 531. 0 is transported to the top block 11 of the straightening table 1. During this loading process, part of the bars 100 can be stored on the chain 2 514. When the straightening table 1 needs the bars 100 immediately, the chain 2 514 and the material separation mechanism 52 are started to immediately separate the bars 100 from the chain 2 514. After that, the position of the bars 100 is adjusted by the clamping grip 12 on the side of the straightening table 1, and the bars 100 are lifted by the top block 11. The straightening rod 2 can press down the bars 100, and different places are pressed down to straighten the bars 100. Therefore, the present invention solves the technical problems of low efficiency and large-scale consumption of manpower and material resources in the prior art in the transfer process of the bars 100, and realizes automatic loading and large-scale storage. The storage area is connected with the straightening area, which improves production efficiency.

[0026] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
