DETAILED DESCRIPTION

[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] Please also read Figures 1 to 6 , now a feeding device for drilling rod processing provided by the present invention is described. The feeding device for drilling rod processing comprises a frame 1, a plurality of material storage racks 2 and a support belt 3; the top of the frame 1 is provided with a tilted feeding platform; the plurality of material storage racks 2 are all arranged on the side of the frame 1 at the high end of the feeding platform, and are arranged at intervals along the length direction of the frame 1; each material storage rack 2 is provided with a column 21, and the height of the top of the column 21 is higher than the height of the high end of the feeding platform; there is an avoidance space between adjacent columns 21; one side of the frame 1 is provided with a baffle 11 for contacting the end of the drilling rod 4; one end of the support belt 3 is connected to the column 21, and the height of the connection position is higher than the height of the high end of the feeding platform; a reversing roller 5 is provided at the high end of the feeding platform, and the other end of the support belt 3 bypasses the reversing roller 5 and is connected to the output shaft of the driving structure, and the height of the driving structure is lower than the height of the reversing roller 5; the total width of the support belt 3 and a single column 21 is less than the distance between two adjacent fork claws on the forklift.

[0020] Compared with the prior art, a plurality of drill rods 4 are lifted to the top of the column 21 by a forklift, and then the forklift moves forward to make the drill rod 4 pass over the column 21 and be located directly above the material storage rack 2, and then the drill rod 4 is placed downward until the drill rod 4 contacts the material storage rack 2, and the fork claws of the forklift continue to descend and separate from the drill rod 4. At this time, the loading process is completed, and the forklift moves backward and leaves the material storage rack 2; the output shaft of the drive structure winds up the support belt 3, which can gradually tighten the support belt 3 and finally straighten the support belt 3. At this time, the support belt 3 forms an inclined surface, and the drill rod 4 moves along the support belt 3 to the loading platform; the baffle 11 on one side of the frame 1 can limit the drill rod 4. Through the above-mentioned arrangement of the present application, the movement and position of the drill rod 4 can be effectively controlled, and the situation that the drill rod 4 is difficult to control when rolling off the forklift is reduced, thereby reducing safety hazards.

[0021] It should be noted that, by setting the total width of the support belt 3 and a single column 21 to be smaller than the distance between two adjacent forks on the forklift, it is convenient for the forklift to insert the fork between the two columns 21, and then it is convenient to place the drill rod 4 from the top of the column 21 to the storage rack 2; by setting the height of the driving structure to be lower than the height of the reversing roller 5, the support belt 3 can bypass the top of the reversing roller 5, and after the support belt 3 is straightened, the drill rod 4 can pass over the reversing roller 5 and finally move to the loading platform.

[0022] In some embodiments, Figures 1 to 6 As shown, the reversing roller 5 is replaced by a winding roller, and the output shaft of the driving structure is connected to one end of the winding roller to drive the winding roller to rotate; the other end of the support belt 3 is connected to the winding roller; wherein, when the support belt 3 is tightened, the connection position between the support belt 3 and the winding roller is located above the winding roller.

[0023] It should be noted that the reversing roller 5 is replaced with a winding roller, and the winding roller is directly driven to rotate by the driving structure, so that the support belt 3 can be wound on the winding shaft at the high end of the loading platform. After being wound in place, the support belt 3 is straightened, and the plurality of drill rods 4 on the winding belt can move toward the upper loading platform. The above-mentioned setting of the present application is intended to illustrate that a reversing shaft or a winding shaft can be set at the high end of the loading platform.

[0024] By setting the connection position between the support belt 3 and the winding roller above the winding roller, when the support belt 3 is tightened, it is convenient for the drill rod 4 to pass from above the winding roller; if the support belt 3 is located below the winding roller, the drill rod 4 will be stuck at the bottom position of the winding roller during movement, and the purpose of loading cannot be achieved.

[0025] In some embodiments, Figures 1 to 6 As shown, there are a plurality of support belts 3 , and the support belts 3 correspond to the material storage racks 2 one by one; each support belt 3 is located at one side of the corresponding material storage rack 2 .

[0026] It should be noted that by setting up a plurality of support belts 3, the gravity on a single support belt 3 can be reduced, thereby reducing the possibility of breakage of the support belt 3; by setting the support belt 3 on one side of the column 21, when the support belt 3 is in a relaxed state, the lowest position of the support belt 3 can be made lower than the lowest position of the storage rack 2; when the drill rod 4 is placed on the storage rack 2, the impact of the drill rod 4 on the support belt 3 can be reduced.

[0027] In some embodiments, Figures 1 to 6As shown, the storage rack 2 has a support surface 22 inclined toward the column 21, and the lower end of the support surface 22 is located at the position of the column 21; wherein, a weight 23 is connected to the support belt 3, and in the initial state, under the gravity of the weight 23, the lowest position of the support belt 3 is lower than the lower end position of the support surface 22. The weight 23 is connected to the support belt 3 through a U-shaped piece 231, and the weight 23 can slide on the support belt 3 through the U-shaped piece 231; both ends of the U-shaped piece 231 have external threads, and both ends of the U-shaped piece 231 pass through the weight 23 and are connected by nuts.

[0028] It should be noted that the support surface 22 is inclined toward the column 21. When a number of drill rods 4 are placed on the storage rack 2, the drill rods 4 will be piled up near the column 21. Through the above arrangement, the situation where the drill rods 4 move to the frame 1 can be reduced. By arranging a weight 23 on the support belt 3, when there is no drill rod 4 on the support belt 3, the support belt 3 will automatically sag under the action of the weight 23, thereby facilitating the lowest position of the support belt 3 to drop below the lowest position of the storage rack 2.

[0029] In some embodiments, Figures 1 to 6 As shown, the loading platform includes a plurality of loading plates 6 arranged at intervals along the length of the frame 1, the top of the loading plate 6 is an inclined surface, and the reversing roller 5 is located at the high end position of the top of the loading plate 6; wherein, a limiting component 7 is provided at the low end position of each loading plate 6, the top of the limiting component 7 has an inclined surface, the limiting component 7 is used to contact the drill rod 4 on the side of the high end of the inclined surface, and the low end position of the inclined surface has a stopper 71; the frame 1 is provided with a pushing mechanism 72 for pushing the drill rod 4 at the lowest position, so that the drill rod 4 moves from the high end of the limiting component 7 to the position of the stopper 71.

[0030] It should be noted that several loading plates 6 form a loading platform, and when the drill rod 4 moves to the top of the loading plate 6, the drill rod 4 moves on the inclined surface at the top of the loading plate 6; the limiting component 7 at the lower end of the loading plate 6 can limit the drill rod 4 to prevent the drill rod 4 from slipping off the loading plate 6; after the manipulator grabs the drill rod 4 at the position of the stop block 71, the pushing mechanism 72 pushes the drill rod 4 in contact with the limiting component 7, and pushes the drill rod 4 to the top of the limiting component 7. At this time, the drill rod 4 can move from the high end of the top of the limiting component 7 to the low end, and finally stop at the position of the stop block 71; the above process is repeated, which is convenient for the manipulator to grab one of the drill rods 4 at a time.

[0031] In some embodiments, Figures 1 to 6As shown, the pushing mechanism 72 includes a pushing component 721 and a first power structure; the pushing component 721 is slidably arranged on one side of the loading plate 6, and is located at the position where the limiting component 7 is connected to the drill rod 4; the first power structure is arranged on the frame 1; the driving end of the first power structure is connected to the pushing component 721, and is used to drive the pushing component 721 to slide up and down; wherein, when the pushing component 721 is pushed into place, the drill rod 4 in contact with the limiting component 7 can move to the high end of the limiting component 7, and move along the inclined surface of the limiting component 7 to the position of the stop block 71.

[0032] It should be noted that a guide rail is provided on the loading plate 6, and a slide groove that slides with the guide rail is provided on the pushing component 721; the first driving structure provides power to the pushing component 721, so that the pushing component 721 can contact with the drill rod 4 and lift the drill rod 4, or the pushing component 721 can be reset downward and separated from the drill rod 4; through the above-mentioned arrangement, the pushing of a single drill rod 4 can be realized at a time, which is convenient for the manipulator to grab one of the drill rods 4.

[0033] Exemplarily, the guide rail is a wedge-shaped guide rail, and the slide groove is a wedge-shaped groove.

[0034] In some embodiments, Figures 1 to 6 As shown, the first power structure includes a driving shaft 722 and a cam 723 . The driving shaft 722 is rotatably matched with the frame 1 . The cam 723 is connected to the driving shaft 722 . The outer peripheral wall of the cam 723 contacts the bottom of the pushing component 721 .

[0035] It should be noted that the drive shaft 722 passes through several loading plates 6, and the drive shaft 722 is connected to the cam of each loading plate 6; a servo motor connected to the drive shaft 722 is provided on the frame 1; after the drive shaft 722 rotates, it can drive several cams to rotate at the same time, and finally make several pushing components 721 push the drill rod 4 synchronously, and push the drill rod 4 to the top position of the limiting component 7.

[0036] In some embodiments, Figures 1 to 6 As shown, a guide structure 8 is provided on the frame 1 and is arranged parallel to the top inclined surface of the loading platform. The distance between the guide structure 8 and the loading platform is greater than the diameter of a single drill rod 4 and less than the sum of the diameters of two drill rods 4.

[0037] It should be noted that the guide structure 8 on the frame 1 can limit the height of the drill rod 4. During the movement of the drill rod 4 on the loading plate 6, it can avoid the situation where the high drill rod 4 passes over the low drill rod 4, further increasing the controllability of the drill rod 4 during movement.

[0038] In some embodiments, Figures 1 to 6As shown, the frame 1 has a truss 12 above the loading platform, and the guide structure 8 includes a guide plate 81 and a second power structure; the guide plate 81 slides with the truss 12 in the height direction, and the bottom of the guide plate 81 is arranged parallel to the top of the loading platform; the second power structure is arranged on the truss 12, and the driving end of the second power structure can drive the guide plate 81 to rise and fall; the second power structure includes a connecting plate 82, a rack 83 and a gear 84; the connecting plate 82 is fixed on the truss 12; the guide plate 81 slides with the connecting plate 82; the rack 83 is connected to the guide plate 81; the gear 84 is rotatably arranged on the connecting plate 82; the gear 84 is meshed with the rack 83.
