Description

Technical Field

[0001] This utility model relates to the field of rotary drilling rig power box assembly technology, and more specifically to a rotary drilling rig power box assembly device. Background Technology

[0002] As a key piece of equipment in modern foundation engineering construction, the power box of a rotary drilling rig is the core component of the entire power transmission system. The power box typically connects multiple heavy components via high-strength bolts, and the precision of these connections directly determines the reliability, service life, and vibration and noise levels of the entire machine. Among these connection structures, the buffer sleeve assembly, as an important flexible connection and vibration damping component, is widely used in the assembly of the power box, playing a crucial role in compensating for alignment errors and absorbing vibration impacts.

[0003] Currently, the assembly process of this buffer sleeve assembly, especially the alignment and connection of the upper and lower flanges, still largely relies on traditional operating methods: mainly using the workshop's bridge crane for hoisting, with multiple operators manually assisting by repeatedly pushing, pulling, and adjusting the heavy workpiece in a suspended state using tools such as pry bars and jacks, which is time-consuming and inefficient. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a rotary drilling rig power box assembly device to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a rotary drilling rig power box assembly device, including a gantry frame and an assembled buffer sleeve. A dual-axis moving module is fixedly connected to the gantry frame. A connecting frame is fixedly connected to one side of the moving part of the dual-axis moving module. Two supports are fixedly connected to the bottom end of the connecting frame. Two T-shaped grooves are opened on the upper surface of the two supports. A T-shaped slide rod is slidably connected in each T-shaped groove. Mirror-shaped inclined plates are fixedly connected to the opposite sides of the T-shaped slide rods on the two supports. Insert rods are fixedly connected to the upper surface of multiple inclined plates. A drive component is provided on the two supports to make the T-shaped slide rods on both sides move synchronously in opposite directions. A frustum base is fixedly connected to the middle position of the bottom inner wall of the gantry frame for supporting the assembled workpiece.

[0006] The buffer sleeve consists of two mirror-arranged connecting flanges and multiple buffer units connecting the two flanges. Each connecting flange consists of two flanges and a vertical cylinder, and each flange has corresponding through holes.

[0007] As a further embodiment of this utility model, the drive assembly includes an arc-shaped plate fixedly connected to the top of two T-shaped slide rods on the same bracket. An end block is fixedly connected to the upper surface of each of the two brackets. A bidirectional synchronous screw is rotatably connected between the opposite sides of the two end blocks through a bearing seat. The bidirectional synchronous screw passes through the two arc-shaped plates and is threadedly connected to a threaded cylinder on the arc-shaped plates. A drive motor that causes the bidirectional synchronous screw to rotate axially is fixedly connected to one side of one of the end blocks.

[0008] As a further embodiment of this utility model, the upper surface of the truncated cone base is provided with a positioning groove that matches the shape of the flange on the flange bracket, and a plurality of positioning rods arranged in a ring array are fixedly connected to the inner wall of the bottom of the positioning groove.

[0009] As a further embodiment of this utility model, a base is fixedly connected to the inner wall of the bottom of the gantry frame and to both sides of the frustum base. The upper surface of the two bases is provided with a groove, and the two grooves are respectively matched with two flanges of different sizes on the two flange frames.

[0010] As a further embodiment of this utility model, a plurality of fixed cylinders arranged in a ring array are fixedly connected to the lower surface of the base, a slider is slidably connected inside the fixed cylinder, a positioning rod is fixedly connected to the upper surface of the slider, the top end of the positioning rod passes through the base, and a spring is provided between the lower surface of the slider and the inner wall of the bottom of the fixed cylinder.

[0011] As a further embodiment of this invention, when the multiple T-shaped slide bars are retracted to their limit positions, the four insert rods correspond to four of the holes on the flange.

[0012] As a further embodiment of this utility model, the four positioning rods one in the groove are in the same position and correspond one-to-one with the four positioning rods two in the positioning slot.

[0013] As a further improvement of this utility model, the edges of the top of the insertion rod are all chamfered.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. This utility model realizes the gripping, lifting, moving and lowering of the upper and lower flange frames through a dual-axis moving module and corresponding insertion rod mechanism. This mechanical automation process replaces the traditional operation method that relies on overhead cranes and repeated manual adjustments, effectively shortening the time consumption and significantly improving the production cycle and overall efficiency of the assembly line.

[0016] 2. This utility model uses a multi-stage positioning mechanism consisting of a positioning groove and positioning rod 2 on a frustum base, and a groove and positioning rod 1 on a base. The upper and lower flanges can be precisely constrained in preset positions before and after assembly, ensuring the coaxiality of all through holes, completely eliminating the error of manual visual inspection, ensuring smooth installation of the power box buffer components, and thus improving the overall assembly quality and product consistency of the power box.

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Reference Figures 1-6This utility model provides a rotary drilling rig power box assembly device, including a gantry frame 1 and an assembled buffer sleeve. A dual-axis moving module 2 is fixedly connected to the gantry frame 1 by bolts. A connecting frame 3 is fixedly connected to one side of the moving part of the dual-axis moving module 2 by bolts. Two supports 4 are fixedly connected to the bottom end of the connecting frame 3 by bolts. Two T-shaped grooves 5 are opened on the upper surface of the two supports 4. A T-shaped sliding rod 6 is slidably connected in each T-shaped groove 5. Mirror-shaped inclined plates 7 are fixedly connected to the opposite sides of the T-shaped sliding rods 6 on the two supports 4 by bolts. Insert rods 8 are fixedly connected to the upper surface of the multiple inclined plates 7 by bolts. The two supports 4 are provided with a drive component that makes the T-shaped sliding rods 6 on both sides move synchronously in opposite directions. A frustum base 16 is fixedly connected to the middle position of the bottom inner wall of the gantry frame 1 by bolts for supporting the assembled workpiece.

[0027] The buffer sleeve consists of two mirror-mounted connecting flanges and multiple buffer units connecting the two flanges. Each connecting flange consists of two flanges and a vertical cylinder.

[0028] It should be noted that the two flanges on the same flange frame have the same inner diameter but different outer diameters, and both flanges have through holes arranged in a ring array. The through holes on the two flanges are in the same position and correspond to each other. During assembly, the two flange frames are set up one above the other in a mirror image, and the two flange frames are connected by a buffer unit.

[0029] It should be noted that the dual-axis moving module 2 is essentially an integration of two high-precision ball screw linear modules, consisting of a set of X-axis modules and a set of Z-axis modules perpendicularly intersecting each other. Power is provided by a motor, and the rotational motion is converted into linear motion by the ball screw pair. The linear guide rail ensures the motion accuracy and rigidity. Finally, through the closed-loop feedback formed by the sensor and control system, a high-precision, high-reliability, and programmable automated positioning function in two-dimensional space is realized. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0030] Through the dual-axis moving module 2 and the corresponding mechanism of the insertion rod 8, the upper and lower flanges are grasped, lifted, moved and lowered. This mechanical automation process replaces the traditional operation method that relies on overhead cranes and repeated manual adjustments, effectively shortening the time consumption and significantly improving the production cycle and overall efficiency of the assembly line.

[0031] In this utility model, the drive assembly includes an arc plate 9 fixedly connected to the top of two T-shaped slide rods 6 on the same bracket 4 by bolts. The upper surfaces of the two brackets 4 are each fixedly connected to an end block 10 by bolts. A bidirectional synchronous screw 11 is rotatably connected between the opposite sides of the two end blocks 10 through a bearing seat. The bidirectional synchronous screw 11 passes through the two arc plates 9 and is threadedly connected to a threaded cylinder on the arc plate 9. A drive motor 12 that causes the bidirectional synchronous screw 11 to rotate axially is fixedly connected to one side of one end block 10 by bolts.

[0032] It should be noted that the drive motor 12 is existing technology, which is a servo motor with an encoder. The number of rotations and rotation angle of the motor output shaft are controllable and have high precision. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0033] In this application, the inner wall of the threaded cylinder on the arc plate 9 is provided with an annular groove in the axial direction. A nylon 66 damping ring with a Shore hardness of 85A is embedded in the groove. The continuous axial clamping force generated by its elastic deformation forms a helical angle interference fit with the surface of the bidirectional synchronous screw 11 at 15°-20°. When the threaded pair is subjected to axial vibration load, the nylon insert can generate a maximum elastic compression of 0.3mm, which increases the friction coefficient between the thread contact surfaces from 0.15 to 0.68 (tested according to ASTM D1894 standard), effectively suppressing the loosening displacement caused by thread springback.

[0034] During assembly, first adjust the vertical position of the dual-axis moving module 2 so that the top of the insertion rod 8 is lower than the upper flange of the lower flange frame. Then, start the drive motor 12 to make the T-shaped sliding rods 6 on both sides move towards each other, thereby driving the inclined plate 7 at its end and the insertion rod 8 to retract inward, so that the four insertion rods 8 are precisely aligned with the four through holes of the upper flange frame. Then, control the Z-axis of the dual-axis moving module 2 to rise so that the insertion rod 8 is inserted into the corresponding through hole of the upper flange of the lower flange frame, and the lower flange frame is hoisted.

[0035] Furthermore, when the multiple T-shaped slide bars 6 are retracted to their limit positions, the four insert rods 8 correspond to four of the holes on the flange, and the edges of the top of each insert rod 8 are chamfered.

[0036] In this utility model, the upper surface of the truncated cone base 16 is provided with a positioning groove 20 that matches the shape of the flange on the flange bracket. Multiple positioning rods 21 arranged in a ring array are fixedly connected to the bottom inner wall of the positioning groove 20 by bolts.

[0037] The lower flange to be assembled is hoisted and placed on the bottom pedestal 16. The positioning groove 20 on the upper surface of the pedestal 16 and the positioning rod 21 inside it can accurately and initially position the lower flange of the lower flange to prevent it from moving horizontally.

[0038] Furthermore, bases 13 are bolted to the inner wall of the bottom of the gantry frame 1 on both sides of the frustum base 16. The upper surface of each base 13 has a groove 14, which is matched with two flanges of different sizes on the two flanges respectively.

[0039] Furthermore, the four positioning rods 18 in the groove 14 are in the same position and correspond one-to-one with the four positioning rods 21 in the positioning groove 20.

[0040] Through a multi-stage positioning mechanism consisting of the positioning groove 20 and positioning rod 21 on the truncated cone base 16, and the groove 14 and positioning rod 18 on the base 13, the upper and lower flanges can be precisely constrained in the preset position before and after assembly, ensuring the coaxiality of all through holes, completely eliminating the error of manual visual inspection, ensuring smooth installation of the power box buffer components, thereby improving the overall assembly quality and product consistency of the power box.

[0041] In this utility model, a plurality of fixed cylinders 15 arranged in a ring array are fixedly connected to the lower surface of the base 13 by bolts. A slider 17 is slidably connected inside the fixed cylinder 15. A positioning rod 18 is fixedly connected to the upper surface of the slider 17 by bolts. The top end of the positioning rod 18 passes through the base 13. A spring 19 is provided between the lower surface of the slider 17 and the bottom inner wall of the fixed cylinder 15.

[0042] The positioning rod 18 in the base 13 is equipped with a spring 19 mechanism, which avoids rigid collisions and can effectively absorb minor impacts and deviations generated during hoisting and placement, protecting the precision-machined surface of the flange and the buffer unit, and reducing scrap rate and maintenance costs.

[0043] Before assembly, the two flanges are first hoisted into the grooves 14 on the two bases 13 respectively. When the flange enters the groove 14, it will press the positioning rod 18 to move downward, thereby compressing the spring 19 through the slider 17. After the flange is fully embedded in the groove 14, the flange is rotated by manual intervention. After the through hole on the flange coincides with the positioning rod 18, the spring 19 releases its elastic force and drives the positioning rod 18 to move upward through the slider 17, thus embedding it into the corresponding through hole on the flange, thereby completing the precise positioning of the flange.

[0044] After the lower flange is hoisted, install the buffer unit on it. The buffer unit is installed in the through hole of the upper flange of the lower flange. After the buffer unit is installed, repeat the hoisting steps of the lower flange to hoist the upper flange directly above the lower flange on which the buffer unit is installed. Then slowly move the upper flange downward until the through hole of the lower flange of the upper flange covers the top of the multiple buffer units. Then fix the upper flange to the buffer unit to complete the assembly.

[0045] The use of this utility model involves the following steps:

[0046] S1: Before assembly, firstly, the two flanges are respectively hoisted into the grooves 14 on the two bases 13. When the flange enters the groove 14, it will squeeze the positioning rod 18 to move downward, thereby squeezing the spring 19 through the slider 17 to retract. After the flange is fully embedded in the groove 14, the flange is rotated by manual intervention. After the through hole on the flange coincides with the positioning rod 18, the spring 19 releases its elastic force and drives the positioning rod 18 to move upward through the slider 17, and then embeds it into the corresponding through hole on the flange, thereby completing the precise positioning of the flange.

[0047] S2: During assembly, first adjust the vertical position of the dual-axis moving module 2 so that the top of the insertion rod 8 is lower than the upper flange of the lower flange. Then start the drive motor 12 to make the T-shaped sliding rods 6 on both sides move towards each other, thereby driving the inclined plate 7 at its end and the insertion rod 8 to retract inward, so that the four insertion rods 8 are precisely aligned with the four through holes of the upper flange. Then control the Z-axis of the dual-axis moving module 2 to rise so that the insertion rod 8 is inserted into the corresponding through hole of the upper flange of the lower flange, and the lower flange is hoisted.

[0048] S3: The lower flange to be assembled is hoisted and placed on the bottom truncated cone 16. The positioning groove 20 on the upper surface of the truncated cone 16 and the positioning rod 21 inside it can accurately and initially position the lower flange of the lower flange to prevent it from moving horizontally.

[0049] S4: After the lower flange is hoisted, install the buffer unit on it. The buffer unit is installed in the through hole of the upper flange of the lower flange. After the buffer unit is installed, repeat the hoisting steps of the lower flange to hoist the upper flange directly above the lower flange where the buffer unit is installed. Then slowly move the upper flange downward until the through hole of the lower flange of the upper flange covers the top of multiple buffer units. Then fix the upper flange to the buffer unit to complete the assembly.

[0050] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
