Description
Technical Field
[0001] The invention relates to the technical field of valve box processing equipment, and in particular to an angle-adjustable drilling rig supporting device for valve box processing. Background Art
[0002] The valve box is a valve composed of a valve body and two or more valve discs. It is usually a combination of two or more stop valves or check valves. The manufacturing process of the valve box is divided into multiple steps, among which the hole processing of the valve box is a relatively important link in the valve box manufacturing process. Its processing quality and precision directly affect the performance and service life of the valve box. The hole processing of the traditional valve box mostly places the valve box in a boring machine, and then uses a lateral displacement drilling rig to drill the processing holes on the valve box. However, the traditional drilling rig only has a lateral displacement function and cannot adjust the angle. When drilling inclined holes, it is impossible to use a traditional drilling rig for drilling. When it is necessary to drill inclined holes, the drilling rig needs to be installed on a support device that can adjust the angle. The existing drilling rig angle adjustment device has a limited adjustment range, and most of them can only change the elevation angle of the drilling rig. In addition, the traditional drilling rig angle adjustment device mostly uses the cooperation of a gear set to achieve the angle change of the drilling rig. However, the volume and gravity of the drilling rig used for the valve box are relatively large. The traditional angle adjustment device is prone to problems such as unstable support, thread slippage and tooth stripping.

[0016] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0017] refer to Figures 1 to 13 The angle-adjustable drilling rig support device for valve box processing shown in the figure comprises a rotating assembly, a pitch adjustment assembly and a tilting assembly. The rotating assembly comprises a motor 1, a bracket 2 and a vertical shaft 3. The vertical shaft 3 is vertically connected to the bracket 2 for rotation (such as Figure 6 As shown in the figure, the motor 1 is vertically fixedly connected to the bracket 2, and the output end of the motor 1 is connected to the vertical axis 3. The pitch adjustment component includes a vertical plate 4, a horizontal axis 5 and a circular lifting frame 6. The horizontal axis 5 is rotatably connected to the top of the vertical axis 3, the vertical plate 4 is fixedly connected to the horizontal axis 5, and a circle of annular grooves 7 are arranged in the circular lifting frame 6. Both ends of the horizontal axis 5 are provided with levers 8, each lever 8 is L-shaped, and one end of each lever 8 is formed with a ball head 9 that slides in the annular groove 7. The tilt assembly includes a swing frame 10, an adjustment mechanism and a locking mechanism. The swing frame 10 is arranged on the side of the vertical plate 4, and a rotating shaft 11 connected to the vertical plate 4 is provided on the swing frame 10. The adjustment mechanism and the locking mechanism are both arranged on the vertical plate 4. The adjustment mechanism is used to drive the rotating shaft 11 to rotate (as shown in the figure). Figure 3 As shown), the locking mechanism is used to lock the rotating shaft 11.
[0018] The device is used to adjust the drilling rig at multiple angles. In actual use, the drilling rig is fixed on the swing frame 10, and the adjustment mechanism is used to drive the rotating shaft 11 to rotate, so as to realize the left and right swing of the swing frame 10, and finally realize the tilt adjustment of the drilling rig. When the inclination angle of the drilling rig is determined, the locking mechanism is used to lock the rotating shaft 11, so as to ensure that the swing frame 10 can hover at the current position; The pitch adjustment assembly of the device is used to adjust the pitch angle of the drilling rig. The specific process is as follows: when the circular lifting frame 6 rises, the circular lifting frame 6 will synchronously drive the two levers 8 to rotate upward, and the two levers 8 will drive the vertical plate 4 to rotate through the horizontal axis 5. At this time, the drilling machine arranged on the swing frame 10 will swing down; when the circular lifting frame 6 descends, the two levers 8 will drive the vertical plate 4 to rotate in the opposite direction through the horizontal axis 5. At this time, the drilling machine arranged on the swing frame 10 will be lifted up, and finally the pitch adjustment of the drilling rig is realized by the lifting and lowering of the circular lifting frame 6; The rotating assembly of the device is used to drive the drilling rig to rotate. The specific process is as follows: when the motor 1 is started, the motor 1 will drive the horizontal axis 5 to rotate through the vertical axis 3. At this time, the horizontal axis 5 will rotate about the axial direction of the vertical axis 3. When the horizontal axis 5 rotates, the vertical plate 4 will drive the drilling rig on the swing frame 10 to rotate, so as to adjust the horizontal swing angle of the drilling rig. During the rotation of the horizontal axis 5, the ball head 9 on each lever 8 will slide in the annular groove 7, so as to ensure that the pitch adjustment and the horizontal swing adjustment of the drilling rig will not affect each other.
[0019] In order to show the specific structure of the adjustment mechanism and the swing frame 10, the following features are set: The swing frame 10 includes a rotating plate 12 and a bracket 13. The rotating plate 12 is vertical, and the rotating shaft 11 is formed on one side of the rotating plate 12 (such as Figure 4 As shown in the figure, the bracket 13 is fixed to the other side of the rotating plate 12, the adjusting mechanism includes a reciprocating screw 14 and two groups of lifting members, the reciprocating screw 14 is vertically connected to the side of the vertical plate 4 where the swing frame 10 is not provided, each group of lifting members includes a slider 15 and a lifting rod 16, the slider 15 is slidably connected to the vertical plate 4 along the vertical direction, the reciprocating screw 14 is provided with two groups of threaded portions with opposite rotation directions, each slider 15 is fixed with a threaded sleeve 17, the two threaded sleeves 17 are respectively threadedly matched with the two threaded portions on the reciprocating screw 14, the two lifting rods 16 are symmetrically arranged on one side of the rotating plate 12, and the two ends of each lifting rod 16 are respectively connected to the slider 15 and the outer wall of the rotating plate 12.
[0020] Since the two threaded sleeves 17 are respectively threadedly matched with the two threaded parts on the reciprocating screw 14, when the reciprocating screw 14 rotates, the two sliders 15 will move toward or away from each other. When the two sliders 15 move toward each other, the two lifting rods 16 will rise and fall respectively. At this time, the rotating plate 12 will be driven to rotate to one side. When the two sliders 15 move away from each other, the two lifting rods 16 will fall and rise respectively. At this time, the rotating plate 12 will be driven to rotate to the other side. Finally, the swing frame 10 is driven to swing left and right in the above manner.
[0021] In order to show how the two ends of the lifting rod 16 are connected to the slider 15 and the rotating plate 12, the following features are set: A No. 1 protrusion 18 and a No. 2 protrusion 19 are respectively formed at both ends of each slider 15, and the two sliders 15 are spaced apart in the vertical direction. A No. 1 limit rod 20 is fixedly provided on the No. 1 protrusion 18 in the lower slider 15, which is vertically upward. The No. 1 limit rod 20 passes through the No. 1 protrusion 18 in the upper slider 15, and a No. 2 limit rod 21 is fixedly provided on the No. 2 protrusion 19 in the upper slider 15, and the No. 2 limit rod 21 passes through the No. 2 protrusion 19 in the lower slider 15. A connecting plate 22 is fixedly provided on the No. 1 limit rod 20 and the No. 2 limit rod 21, and a horizontal fixing pin 23 is fixedly provided on the connecting plate 22. Two symmetrical strip through grooves 24 are provided on the vertical plate 4, and the two fixing pins 23 pass through the two strip through grooves 24 respectively. Two symmetrical connecting pins 25 are formed on the side of the rotating plate 12 facing the vertical plate 4, and the two ends of each lifting rod 16 are rotatably connected with the fixing pin 23 and the connecting pin 25 respectively.
[0022] When the reciprocating screw 14 rotates, the two sliders 15 will move toward or away from each other. During this process, the No. 1 limit rod 20 and the No. 2 limit rod 21 will respectively drive the two fixed pins 23 to slide in the corresponding strip-shaped through grooves 24 through the two connecting plates 22, and the sliding directions of the two fixed pins 23 are opposite. When the two fixed pins 23 are respectively raised and lowered, the two lifting rods 16 will respectively realize the rotation of the turn plate 12 through the corresponding connecting pins 25. In actual use, the drilling rig will only adjust its tilting angle within a small range, so the swing range of the swing frame 10 is very small, so the lifting rod 16 will not break when driving the turn plate 12.
[0023] In order to show the specific structure of the locking mechanism, the following features are set: The lower end of the reciprocating screw rod 14 is provided with a spline portion 26 (such as Fig.13 As shown in FIG. 1 ), the locking mechanism includes a lock plate 27, an arc-shaped clamping plate 28, a connecting piece, a rotating cap 29 and a spring 30. The lock plate 27 is coaxially fixedly connected to the rotating shaft 11 (as shown in FIG. 1 ). Figure 7 As shown), the lock plate 27 is located beside the spline portion 26, the arc-shaped clamping plate 28 is arranged above the lock plate 27, and two symmetrical guide blocks 31 are formed on the arc-shaped clamping plate 28, each guide block 31 is slidably connected to the vertical plate 4 in the vertical direction, the rotating cap 29 is sleeved on the spline portion 26, and a circle of tooth grooves 32 are formed in the rotating cap 29, and the tooth grooves 32 are engaged with the spline portion 26. The spring 30 is vertically arranged in the rotating cap 29, and the two ends of the spring 30 are respectively in conflict with the bottom end of the spline portion 26 and the inner bottom wall of the rotating cap 29. The connecting member includes a collar 33 and two symmetrical connecting feet 34, and the collar 33 is sleeved on the upper end of the rotating cap 29 (as shown in FIG. Fig.10 As shown in the figure, a stopper is provided on the rotating cap 29 for limiting the axial displacement of the collar 33, and each connecting foot 34 connects the collar 33 and the corresponding guide block 31.
[0024] When the swing frame 10 rotates, the drill rig on the swing frame 10 will swing to one side. At this time, the threaded sleeve 17 cooperates with the thread of the reciprocating screw rod 14 to prevent the slider 15 from sliding on its own, and finally ensures that the drill rig will hover in the current state after swinging. However, in actual use, the size and weight of the drill rig are relatively large. In order to prevent the reciprocating screw rod 14 and the threaded sleeve 17 from slipping, the device is provided with a locking mechanism, which plays an auxiliary clamping role and is used to lock the rotating shaft 11 to prevent the swing frame 10 from swinging on its own. When the locking plate 27 is in the state of being locked, the spring 30 releases the elastic force to drive the rotating cap 29 to descend. When the rotating cap 29 descends, the rotating cap 29 drives the collar 33 to descend through the limiter. When the collar 33 descends, the collar 33 will respectively drive the two guide blocks 31 to descend through the two connecting legs 34. Finally, the two guide blocks 31 will drive the arc clamping plate 28 downward to press against the locking plate 27, and the peripheral wall of the locking plate 27 and the inner arc surface of the arc clamping plate 28 are rough surfaces. Therefore, when the arc clamping plate 28 is pressed on the locking plate 27, the locking plate 27 will be locked. When it is necessary to adjust the swing frame 10 for rotation, the rotating cap 29 is lifted. In this process, the rotating cap 29 will drive the arc clamping plate 28 to rise through the collar 33 and the connecting leg 34, so that the arc clamping plate 28 is separated from the locking plate 27. When the arc clamping plate 28 is separated from the locking plate 27, the rotating cap 29 is rotated. At this time, the reciprocating screw rod 14 is driven to rotate through the cooperation of the tooth groove 32 and the spline portion 26.
[0025] In order to show the specific structure of the stopper and how the collar 33 is installed on the rotating cap 29, the following features are provided: The collar 33 includes two semicircular rings 35 that can be aligned with each other, and each connecting foot 34 is connected to a corresponding semicircular ring 35 (such as Fig.12 As shown in the figure, each semicircular ring 35 is embedded with a semicircular slip ring 36, and the limiting member includes a No. 1 convex ring 37 and a No. 2 convex ring 38. The No. 1 convex ring 37 and the No. 2 convex ring 38 are both formed on the outer wall of the upper end of the rotating cap 29, and the No. 1 convex ring 37 and the No. 2 convex ring 38 are distributed at intervals along the axial direction of the rotating cap 29.
[0026] When installing the collar 33, the two semicircular rings 35 are sleeved on the rotating cap 29, and then the two semicircular rings 35 are fixedly connected. When the two semicircular rings 35 are aligned and fixed, the formed collar 33 will be located between the No. 1 convex ring 37 and the No. 2 convex ring 38. The No. 1 convex ring 37 and the No. 2 convex ring 38 are used to limit the axial displacement of the collar 33 on the rotating cap 29, and when the two semicircular rings 35 are aligned, the two semicircular slip rings 36 will also be aligned. The semicircular slip rings 36 are used to reduce the friction between the semicircular rings 35 and the rotating cap 29.
[0027] In order to show how the vertical axis 3 is installed, the following features are set: A bottom plate 39 (such as Figure 6 As shown in the figure, the bracket 2 includes a cylindrical shell 40, a support plate 41 and a plurality of support legs 42. The cylindrical shell 40 is vertically arranged above the bottom plate 39. The plurality of support legs 42 are evenly distributed along the circumferential direction of the cylindrical shell 40. Each support leg 42 connects the cylindrical shell 40 with the bottom plate 39. The support plate 41 is horizontally fixedly connected to the plurality of support legs 42. The motor 1 is vertically fixedly connected to the support plate 41. A plurality of bearings 43 evenly distributed along the vertical direction are fixedly arranged in the cylindrical shell 40. The vertical shaft 3 passes through the cylindrical shell 40, and the vertical shaft 3 is connected to the plurality of bearings 43.
[0028] When the motor 1 is started, the motor 1 will drive the vertical shaft 3 to rotate. When the vertical shaft 3 rotates, the vertical shaft 3 will drive the horizontal shaft 5 to rotate. Finally, the horizontal shaft 5 will drive the vertical plate 4 and the drilling rig thereon to rotate. The vertical shaft 3 is rotated by a plurality of bearings 43. When the vertical shaft 3 is connected to the plurality of bearings 43, the axial displacement of the vertical shaft 3 will be restricted. At this time, the vertical shaft 3 can only rotate, thereby ensuring that the vertical shaft 3 will not be axially displaced when the circular lifting frame 6 is raised or lowered.
[0029] In order to show how the horizontal axis 5 and the vertical plate 4 are connected to the vertical axis 3, the following features are set: A guide sleeve 44 is formed on the top of the vertical shaft 3, and the horizontal shaft 5 passes through the guide sleeve 44. A flat plate 45 is formed on the bottom of the vertical plate 4, and a plurality of fixing sleeves 46 (such as Fig. 9 As shown in the figure), the transverse axis 5 passes through the fixing sleeve 46, and each fixing sleeve 46 is fixedly connected to the transverse axis 5.
[0030] The horizontal axis 5 is rotatably connected to the vertical axis 3 through a guide sleeve 44. During actual installation, both sides of the guide sleeve 44 are provided with retaining rings (not shown in the figure) for limiting the axial displacement of the horizontal axis 5. When the circular lifting frame 6 is raised or lowered, the circular lifting frame 6 will drive the horizontal axis 5 to rotate through the levers 8 at both ends of the horizontal axis 5. During this process, the horizontal axis 5 will rotate in the guide sleeve 44. At the same time, the horizontal axis 5 will drive the vertical plate 4 to rotate through a plurality of fixing sleeves 46. When the vertical plate 4 rotates, the drilling machine arranged on the swing frame 10 will perform pitch adjustment.
[0031] In order to show how the ball head 9 is installed in the annular groove 7, the following features are provided: The circular lifting frame 6 includes an annular shell 47, a first annular plate 48 and a second annular plate 49. The annular shell 47 is vertical, the first annular plate 48 is formed in the annular shell 47, the second annular plate 49 is fixed in the annular shell 47, and the second annular plate 49 is located above the first annular plate 48. The annular groove 7 is formed between the annular shell 47, the first annular plate 48 and the second annular plate 49.
[0032] The No. 2 annular plate 49 and the annular shell 47 are detachably connected. Before installing the circular lifting frame 6, the two levers 8 are first fixed to the two ends of the horizontal axis 5 respectively, and then the annular shell 47 is passed upward through the bracket 2. At this time, the ball head 9 is made to conflict with the No. 1 annular plate 48 in the annular shell 47, and finally the No. 2 annular plate 49 is fixed in the annular shell 47. When the No. 2 annular plate 49 is fixed, the ball head 9 will be clamped between the No. 1 annular plate 48 and the No. 2 annular plate 49. Therefore, when the circular lifting frame 6 is lifted and lowered as a whole, the ball head 9 clamped between the No. 1 annular plate 48 and the No. 2 annular plate 49 will be driven to be lifted and lowered synchronously, and finally the ball head 9 drives the lever 8 to drive the horizontal axis 5 to rotate.
[0033] In order to show how the circular lifting frame 6 is raised and lowered, the following features are set: A plurality of hydraulic cylinders 50 evenly distributed along the circumferential direction of the annular shell 47 are fixedly provided on the bottom plate 39 . Each hydraulic cylinder 50 is vertical, and the output end of each hydraulic cylinder 50 is upwardly connected to the first annular plate 48 .
[0034] Several hydraulic cylinders 50 work synchronously, and the entire circular lifting frame 6 is driven to be lifted and lowered by the hydraulic cylinders 50. When the circular lifting frame 6 stops lifting and lowering, the hydraulic cylinders 50 will keep the circular lifting frame 6 suspended at the current position through hydraulic pressure maintenance, so as to prevent the circular lifting frame 6 from axial displacement by itself.
[0035] Working principle: The device is used to adjust the drilling rig at multiple angles. In actual use, the drilling rig is fixed on the swing frame 10, and the adjustment mechanism is used to drive the rotating shaft 11 to rotate, so as to realize the left and right swing of the swing frame 10, and finally realize the tilt adjustment of the drilling rig. When the inclination angle of the drilling rig is determined, the locking mechanism is used to lock the rotating shaft 11, so as to ensure that the swing frame 10 can hover at the current position; The pitch adjustment assembly of the device is used to adjust the pitch angle of the drilling rig. The specific process is as follows: when the circular lifting frame 6 rises, the circular lifting frame 6 will synchronously drive the two levers 8 to rotate upward, and the two levers 8 will drive the vertical plate 4 to rotate through the horizontal axis 5. At this time, the drilling machine arranged on the swing frame 10 will swing down; when the circular lifting frame 6 descends, the two levers 8 will drive the vertical plate 4 to rotate in the opposite direction through the horizontal axis 5. At this time, the drilling machine arranged on the swing frame 10 will be lifted up, and finally the pitch adjustment of the drilling rig is realized by the lifting and lowering of the circular lifting frame 6; The rotating assembly of the device is used to drive the drilling rig to rotate. The specific process is as follows: when the motor 1 is started, the motor 1 will drive the horizontal axis 5 to rotate through the vertical axis 3. At this time, the horizontal axis 5 will rotate about the axial direction of the vertical axis 3. When the horizontal axis 5 rotates, the vertical plate 4 will drive the drilling rig on the swing frame 10 to rotate, so as to adjust the horizontal swing angle of the drilling rig. During the rotation of the horizontal axis 5, the ball head 9 on each lever 8 will slide in the annular groove 7, so as to ensure that the pitch adjustment and the horizontal swing adjustment of the drilling rig will not affect each other.
