Description

Technical Field

[0001] This utility model belongs to the field of drilling technology, and in particular relates to a rotary table drilling device. Background Technology

[0002] The crane turntable is a key component of the crane. It is mounted on the slewing bearing and has the function of rotating around the base. The turntable provides a platform for the installation of components such as the boom, tower, A-frame, hoisting mechanism, and slewing mechanism.

[0003] Current drilling equipment commonly employs a single-hole sequential drilling method when drilling crane turntables. Given that crane turntables typically have multiple hole positions, this single-hole drilling method significantly reduces the efficiency of the drilling process. This reduced efficiency negatively impacts the overall processing efficiency of the crane turntable, resulting in insufficient practicality of the drilling equipment in real-world applications.

[0027] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0028] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Please see Figures 1 to 5 This utility model provides a rotary table drilling device, including a support base 1, a support plate 2 installed at the bottom of the support base 1, a base 3 installed on the upper side of the support base 1, a support column 4 installed on the base 3, a fixing plate installed on the top of the support column 4, and a lifting seat 5 slidably sleeved on the support column 4; an electric push rod 6 is installed on the fixing plate, a first connecting rod 7 is installed at the output end of the electric push rod 6, and the other end of the first connecting rod 7 is fixedly connected to the lifting seat 5; a drilling assembly is installed on the lifting seat 5, and a placement member aligned with the drilling assembly is installed on the upper side of the support base 1.

[0030] Using the above solution: When drilling is required on the turntable, the operator places the turntable on the placement piece and ensures that the position on the turntable to be drilled is aligned with the drilling assembly. Then, by extending the output end of the drive electric push rod 6, the first connecting rod 7 is pushed to extend synchronously. During the movement, the first connecting rod 7 will drive the lifting seat 5 to slide down along the support column 4 to the preset position. When the lifting seat 5 reaches the designated position, the drilling assembly will then drill multiple holes on the turntable.

[0031] Furthermore, the drilling assembly includes a mounting shell 8 fixedly connected to the lifting seat 5; a first motor 9 is mounted on the mounting shell 8; a first rotating shaft 10 is mounted on the output end of the first motor 9, and the other end of the first rotating shaft 10 is rotatably connected to the bottom wall of the mounting shell 8.

[0032] Furthermore, a first gear 11 is mounted on the first rotating shaft 10; a plurality of second gears 12 are meshed on one side of the first gear 11, and a second rotating shaft 13 is mounted on the central part of each of the second gears 12; the second rotating shaft 13 is rotatably connected to the mounting shell 8.

[0033] Furthermore, the second rotating shaft 13 passes through the mounting shell 8, and a drill bit 14 is connected to one end of the second rotating shaft 13.

[0034] The above scheme is adopted as follows: During use, as the lifting platform 5 continues to descend, the output end of the first motor 9 begins to rotate, thereby driving the first rotating shaft 10 to rotate synchronously. The first gear 11 on the first rotating shaft 10 rotates accordingly and meshes with multiple second gears 12, causing the multiple second gears 12 to rotate synchronously. The rotation of the second gears 12 drives the second rotating shaft 13 to rotate, thereby causing the drill bit 14 on the second rotating shaft 13 to start working. As the lifting platform 5 continues to descend, multiple drill bits 14 can simultaneously perform multi-hole drilling operations on the turntable. By having multiple drill bits 14 work simultaneously, the inefficient method of processing one hole at a time is avoided, thereby effectively shortening the processing time and improving the drilling efficiency.

[0035] Furthermore, the placement component includes a motor protective housing 15 installed on the upper side of the support 1; a second motor 16 is installed inside the motor protective housing 15, and the output end of the second motor 16 passes through the motor protective housing 15.

[0036] Furthermore, a placement plate 17 is installed at the output end of the second motor 16, and the placement plate 17 is aligned with the position of the mounting shell 8.

[0037] Using the above scheme: In use, the turntable is placed on the placement plate 17, and then the lifting seat 5 drives the drill bit 14 to descend while the drill bit 14 rotates. When the drill bit 14 reaches the preset position and contacts the turntable, the lifting seat 5 continues to descend, and the drill bit 14 drills holes in the turntable. After the first drilling is completed, if there are other holes that need to be drilled, the lifting seat 5 will move upward, and the drill bit 14 will leave the turntable. At this time, the second motor 16 starts to work, and its output end drives the placement plate 17 to rotate, thereby aligning the un-drilled holes with the drill bit 14. After the second motor 16 stops, the drill bit 14 descends again to drill new holes.

[0038] The following explanation addresses the situation where the placement plate 17 needs to be rotated:

[0039] For example, if there are sixteen holes on the turntable that need to be drilled, but there are only eight drill bits 14, then only eight holes can be processed when drilling the turntable for the first time. When the remaining eight holes need to be processed, the lifting seat 5 needs to be moved upward so that the placement plate 17 drives the turntable to rotate, aligning the remaining holes with the drill bits 14. Then the drill bits 14 are lowered again for the second drilling process.

[0040] It should be noted that: First, the number of drill bits 14 can be adjusted according to the hole positions on the turntable. If there are too many holes to drill, the rotation of the placement plate 17 can be used in conjunction with the drill bits 14 to perform multiple drilling operations. The distance between the drill bits 14 can be adjusted according to actual needs. Second, a fixing mechanism can be installed on the placement plate 17. After the turntable is placed on the placement plate 17, it can be fixed using the fixing mechanism to facilitate subsequent drilling operations. Third, during drilling, liquid can be added to the drill bits 14 to cool them and prevent them from overheating. Fourth, the bottom of the placement plate 17 is rotatably connected to the top of the motor protective housing 15, which supports the rotation of the placement plate 17 using the motor protective housing 15.

[0041] Furthermore, the drill bits 14 are evenly arranged on the outside of the first gear 11, and the drill bits 14 are engaged with the second rotating shaft 13.

[0042] The working principle of this utility model:

[0043] When drilling is required on the turntable, the turntable is placed on the placement plate 17, ensuring that the position of the turntable to be drilled is aligned with the drill bit 14. Then, by extending the output end of the drive electric push rod 6, the first connecting rod 7 is pushed to extend synchronously. During the movement of the first connecting rod 7, the lifting seat 5 slides downward along the support column 4. As the lifting seat 5 continues to descend, the output end of the first motor 9 begins to rotate, thereby driving the first rotating shaft 10 to rotate synchronously. The first gear 11 on the first rotating shaft 10 rotates accordingly and meshes with multiple second gears 12, causing multiple second gears 12 to rotate synchronously. The rotation of the second gears 12 drives the second rotating shaft 13 to rotate, thereby causing the drill bit 14 on the second rotating shaft 13 to start working. As the lifting seat 5 continues to descend, multiple drill bits 14 can simultaneously perform multi-hole drilling operations on the turntable.
