Technical Field

[0001] The utility model relates to the technical field of drilling rigs, in particular to a positioning device for a rotary platform of a drilling rig. Background Technique

[0002] A drilling rig is usually applied to construction sites, road paving, tunnel construction and other occasions. It is used in cooperation with a rotary platform to support the drilling rig while being able to rotate the drilling rig to adjust it to the required processing position, thus facilitating subsequent drilling operations. During the processing, a positioning device is needed to improve the accuracy of the drilling rig during processing.

[0003] A positioning device and a drilling rig with the publication number CN207686613U have a fixed tooth block as the main body. A first locking mechanism and a second locking mechanism are respectively arranged on the fixed tooth block. The fixed tooth block is rotatably installed on the rotary platform. When in the first working position, it meshes with the external gear ring of the slewing bearing on the bottom side of the rotary platform. At this time, the first locking mechanism is locked. When the fixed tooth block is in the second working position, it is pulled out from the external gear ring and locked by the second locking mechanism. Through the structure of the fixed tooth block and the locking mechanism, the drilling rig can be limited during drilling to prevent the position deviation of the drilling rig from affecting the quality of the drilling process.

[0004] There are still problems in the above-mentioned positioning device and drilling rig for a rotary platform of a drilling rig. The positioning device only plays a role in fixing the drilling rig by the cooperation of the fixed tooth block and the external gear ring, and cannot accurately position the drilling rig to the required processing position, resulting in a reduction in the processing accuracy of the drilling rig. Therefore, a positioning device for a rotary platform of a drilling rig is proposed. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art, the positioning device on the market only plays a role in fixing the drilling rig by the cooperation of the fixed tooth block and the external gear ring, and cannot accurately position the drilling rig to the required processing position, resulting in a reduction in the processing accuracy of the drilling rig. The utility model proposes a positioning device for a rotary platform of a drilling rig.

[0012] 2. Through the structural design of a positioning device for a rotating platform of a drilling rig, by setting the fixing mechanism, after the drilling rig is moved to the processing position, control the servo motor to drive the threaded rod at its output end to rotate, thereby pushing the threaded cylinder to translate, so that the extrusion plate translates along the direction of the limit rod, and thus is extruded on the circumferential surface of the support platform to fix it, thereby preventing the position of the drilling rig from shifting during the processing and ensuring that the quality of the drilling process will not decline.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0021] Please refer to Figures 1-4 As shown, a positioning device for a drill rig rotating platform includes a bottom plate 1; a positioning mechanism is arranged on one side of the bottom plate 1, a rotating mechanism is arranged on the top side of the bottom plate 1, a fixing mechanism is arranged on the other side of the bottom plate 1, and a bracket 2 is fixed on one side of the bottom plate 1;

[0022] Please refer to Figure 2As shown, the positioning mechanism includes a bracket 2. A turntable 4 is rotatably installed on the top side of the bracket 2. A plug rod 5 is slidably inserted through a position near the edge of the top side of the turntable 4. A limit seat 6 is fixed to the top end of the plug rod 5. A spring 7 is fixedly connected between the limit seat 6 and the turntable 4. A housing 8 is rotatably sleeved on the circumferential surface of the limit seat 6. Positioning holes 9 are evenly formed on the top side of the bracket 2. One end of the plug rod 5 passes through the turntable 4 and is buckled inside the positioning hole 9. The spring 7 is sleeved on the plug rod 5. A small gear 3 is fixed to the bottom side of the turntable 4 passing through the bracket 2. During operation, when there is a problem that the existing positioning device cannot accurately adjust the drill to the processing position, through the structure of the positioning mechanism, the housing 8 is pulled to drive the plug rod 5 to be withdrawn from the inside of the positioning hole 9. By pushing the housing 8, the turntable 4 is driven to rotate, thereby driving the small gear 3 on its bottom side to rotate. When the plug rod 5 is moved to the required positioning hole 9, the housing 8 is released. At this time, the spring 7 pulls the plug rod 5 to be inserted into the inside of the positioning hole 9 again through its own elastic force, fixing the small gear 3 at the required position, so as to accurately rotate the drill to the required processing position and improve the processing accuracy of the device.

[0023] Please refer to Figure 3 As shown, the rotating mechanism includes a small gear 3. The small gear 3 is rotatably connected to the bracket 2. A large gear 10 is rotatably installed at the center of the top side of the bottom plate 1. The small gear 3 meshes with the large gear 10. A support platform 11 is fixed to the top side of the large gear 10. A drill body 12 is fixed to the top side of the support platform 11. A limit frame 13 is fixed to the circumferential surface of the bottom plate 1. During operation, when there is a problem that the existing positioning device cannot perform the positioning function, through the structure of the rotating mechanism, when the small gear 3 rotates, it drives the meshing large gear 10 to rotate. Thus, with the cooperation of the support platform 11 on the top side of the large gear 10, the drill body 12 is rotated to the required position. At this time, the small gear 3 is fixed, and the drill body 12 will be fixed at the processing position, facilitating subsequent drilling operations, with simple operation and convenient use.

[0024] Please refer to Figure 4As shown in the figure, the fixing mechanism includes a limit frame 13. The side of the limit frame 13 is symmetrically and slidably penetrated by limit rods 14. One end of the inner side of the limit rods 14 is fixed with a pressing plate 15. The center of the side of the limit frame 13 is fixed with a servo motor 17. The output end of the servo motor 17 is fixed with a threaded rod 18, and the threaded rod 18 is rotatably connected to the limit frame 13. The side of the pressing plate 15 is fixed with a threaded cylinder 16, and the threaded rod 18 is installed inside the threaded cylinder 16 by threaded fit; during operation, when there is a gap between the gears, resulting in the problem that the drill will be forced to shift during the drilling process, through the structure of the fixing mechanism, when the drill is moved to the processing position, control the servo motor 17 to drive the threaded rod 18 at the output end to rotate, thereby pushing the threaded cylinder 16 to translate, so that the pressing plate 15 translates along the direction of the limit rod 14, thereby pressing on the circumferential surface of the support table 11 and fixing it, so as to prevent the drill from shifting during the processing process and ensure that the quality of the drilling process will not decline.

[0025] Please refer to Figure 5 As shown in the figure, a rubber pad 19 is fixed on the clamping surface of the pressing plate 15; during operation, when there is a problem that the surface of the support table 11 is smooth and it is easy to loosen after fixation, affecting the quality of the drilling process, through the structure of the rubber pad 19, the friction between the pressing plate 15 and the contact surface of the support table 11 can be increased, thereby preventing the drill from shifting during the processing process and improving the quality of the drilling process.

[0026] Working principle: The drill rig is usually applied to construction sites, road paving, tunnel construction and other occasions. It is used in conjunction with a rotating platform to support the drill rig while being able to rotate the drill rig to adjust it to the required processing position, thus facilitating subsequent drilling operations. During the processing, a positioning device is required to improve the accuracy of the drill rig during processing. The existing positioning device only plays a fixing role for the drill rig by the cooperation of a fixed tooth block and an external gear ring, and cannot accurately position the drill rig to the required processing position, resulting in a reduction in the processing accuracy of the drill rig. To solve this problem, by setting a positioning mechanism and a fixing mechanism, the housing 8 is pulled to drive the insertion rod 5 to be withdrawn from the inside of the positioning hole 9. By pushing the housing 8, the turntable 4 is driven to rotate, thereby driving the small gear 3 at its bottom to rotate. At this time, the small gear 3 drives the large gear 10 meshing with it to rotate. Thus, with the cooperation of the support table 11, the drill rig body 12 is driven to rotate. When the insertion rod 5 moves to the required positioning hole 9, the housing 8 is released. At this time, the spring 7 pulls the insertion rod 5 to be reinstalled into the inside of the positioning hole 9 through its own elastic force, fixing the small gear 3 at the required position. At this time, the drill rig body 12 will be fixed at the required processing position. Then, the servo motor 17 is controlled to drive the threaded rod 18 at its output end to rotate, thereby pushing the threaded barrel 16 to translate, so that the pressing plate 15 translates along the direction of the limiting rod 14, and thus presses on the circumferential surface of the support table 11 to fix it, preventing the drill rig from shifting during processing. After the drilling operation is completed, the servo motor 17 can be controlled to reverse, thereby pulling the pressing plate 15 away from the surface of the support table 11. Similarly, the turntable 4 can be rotated to move the drill rig to the next processing position for the next processing, solving the problem of low processing accuracy of the existing drill rig.
