Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical equipment technology and relates to a clamping device for perforating instruments. Background Technology
[0002] Oil perforation instruments are needed during oil extraction. During maintenance, these instruments need to be clamped and fixed to prevent them from loosening. However, with a wide variety of models and sizes of perforation instruments available, how to clamp them conveniently and how to adapt them to different sizes are problems that urgently need to be solved.
[0003] Chinese Patent (Announcement No. CN211681061U, Publication Date 20201016) discloses a clamping device for processing oil perforation instruments, including a main board and a power mechanism. A positioning bolt is movably mounted on the outer wall of the main board, and a fixed box is mounted on the top right side of the main body. The power mechanism is movably connected to the top of the fixed box, and a working frame is movably mounted on the left side of the outer wall of the power mechanism. A clamping mechanism is movably mounted on the inner wall of the working frame. This clamping device for processing oil perforation instruments features a main board, and the fixed head and the coupling are movably connected. This allows the coupling to be removed from the fixed head by bolts if it becomes damaged and unable to operate after long-term use, enabling repair and replacement of the coupling. This improves the maintenance efficiency of the parts within the device. Simultaneously, the coupling forms a rotating structure with the rotating shaft via the fixed head, allowing the user to start the reduction motor during operation. The reduction motor drives the rotating shaft to rotate, which in turn drives the coupling on the fixed head to rotate.
[0004] However, the above-mentioned clamping device requires the selection of a corresponding working frame according to the size of different oil perforation instruments, and then it is fixed to the fixing head on one side of the rotating shaft through the connector to complete the installation. The disadvantage of this design is that the installation process is complicated and time-consuming. At the same time, the working frame used for clamping cannot adapt to perforation instruments of different sizes, and its adaptability is insufficient. Utility Model Content
[0005] The purpose of this invention is to provide a clamping device for perforating instruments, which solves the problems of existing perforating instrument clamping devices having unreasonable structural settings, being time-consuming and laborious when clamping parts, and having poor adaptability of the working frame used for clamping.
[0006] The technical solution adopted by this utility model is a clamping device for a perforating instrument, including two side seats fixedly installed on the base plate, each side seat having a set of follower components, which are connected to the limiting mechanism via a linkage component; a driving component is provided above one of the side seats, which is simultaneously connected to the toothed column in both sets of follower components; a placement slot is opened through the lower part of each side seat; the lower pressure arc plate in each set of limiting mechanisms is fitted onto the upper part of the placement slot, and a set of supporting components is provided at the lower part of each placement slot.
[0007] The clamping device for a perforating instrument of this utility model is further characterized in that:
[0008] The side seat has a hollow structure.
[0009] A drive assembly is provided above one of the side seats. The output shaft of the forward and reverse motor in the drive assembly is coaxially and fixedly connected to the toothed column in a follower assembly. The track drive in the drive assembly is connected to the outer surface of the two toothed columns.
[0010] The placement slots in the two side seats are coaxially arranged and have the same diameter; in each placement slot, the pressure arc plate is opposite to the arc opening of the support component.
[0011] The structure of the follower component includes a toothed column and a worm gear, with the worm gear located in the internal space of the side seat and fixedly connected to the bottom of the toothed column.
[0012] The structure of the linkage component includes a rotating shaft, a worm gear, and a gear disc. The rotating shaft, worm gear, and gear disc are all located in the internal space of the side seat. The rotating shaft is fitted into a bearing support inside the side seat. The worm gear and gear disc are both fixed to one side of the outer circular surface of the rotating shaft. The worm gear is meshed with the worm.
[0013] The limiting mechanism comprises a hollow frame, the bottom of which is fixedly connected to the top of the outer arc surface of the lower pressure plate. The frame has multiple spaced tooth grooves on its vertical face facing the gear plate, and the frame is connected to the gear plate through these tooth grooves. The internal vertical space of the frame is called the middle groove, and a limiting plate is fitted in the middle groove. The limiting plate is fixed inside the side seat.
[0014] The inner surface of the downward pressure arc plate is fixedly provided with anti-slip material.
[0015] The structure of the supporting component includes an upper supporting arc plate, which is fixedly installed at the lower circumference of the placement groove. Multiple sets of embedded seat sleeves are fixedly arranged at equal intervals along the axial direction at the middle position of the upper supporting arc plate. Multiple embedded slots are spaced apart in each set of embedded seat sleeves, and an embedded seat is installed in each embedded slot.
[0016] The embedded seat has the following structure: a damping spring is included, the fixed end of the damping spring is fixedly connected to the inner wall of the embedded groove, the telescopic end of the damping spring is connected upward to a limiting ring, and a ball is rotatably connected in the groove at the top of the limiting ring.
[0017] The beneficial effects of this utility model are: 1) Two sets of side seats are symmetrically fixedly connected to the top of the base plate. When clamping the perforating instrument, it can be inserted into the two sets of placement slots in sequence so that the position to be repaired is located between the two sets of placement slots. Then, the forward and reverse motors are started and the two sets of toothed columns rotate synchronously in the same direction under the action of the track drive. This causes the worm at the bottom of the toothed column to rotate synchronously and mesh with the worm wheel. As the worm wheel drives the rotating shaft to rotate, the toothed disc on one side of the rotating shaft rotates synchronously and meshes with the frame to move downward until the lower pressure arc plate at the bottom of the frame completes the clamping work of the perforating instrument. It can quickly and stably clamp perforating instruments of various sizes, which is convenient for subsequent maintenance work. 2) An upper support arc plate is provided at the bottom of the placement slot, and three sets of inner seats are equally spaced in the middle of the upper support arc plate. When the perforating instrument passes through the placement slot for clamping and insertion, the ball bearings located at the top of the inner seats will support the perforating instrument and contact and rotate synchronously as the perforating instrument moves, making the insertion of the perforating instrument smoother and reducing wear on the outer surface. In particular, when the frame drives the lower pressure arc plate to move down to complete the clamping of the perforating instrument, the ball bearings will be affected by the downward pressure of the lower pressure arc plate and move downward into the top slot of the inner seat. This can prevent the perforating instrument from becoming loose in the placement slot due to the influence of the ball bearings during clamping and maintenance. Furthermore, a damping spring is provided at the bottom of the ball bearings. After maintenance is completed, the lower pressure arc plate will disengage from the top of the perforating instrument. At this time, the damping spring will elastically reset and drive the ball bearings to move upward. Similarly, it is convenient for the perforating instrument to be smoothly pulled out of the placement slot. Attached Figure Description

[0025] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0026] Reference Figure 1 The structure of this utility model includes a base plate 1 as an integral support. A hollow side seat 11 is fixedly installed on each of the two sides of the upper surface of the base plate 1. Each side seat 11 contains a set of follower components 3, a linkage component 4, and a limiting mechanism 5. The follower components 3 are connected to the limiting mechanism 5 via the linkage component 4. Each set of follower components 3 consists of a toothed column 31 and a worm gear 32 coaxially fixedly connected. A drive component 2 is installed above one of the side seats 11. The drive component 2 consists of a forward and reverse motor 21 and a track 22. The output shaft of the forward and reverse motor 21 is coaxially fixedly connected downwards to a toothed column 31. The track 22 is connected to the outer surfaces of the two toothed columns 31. A placement slot 12 is provided through the lower side of each side seat 11. The placement slots 12 in the two side seats 11 are coaxially arranged and have the same diameter.
[0027] Each set of limiting mechanism 5 is fixedly connected by an upper frame 51 and a lower pressing arc plate 52. The pressing arc plate 52 is fitted on the upper part of the placement slot 12 of the side seat 11. A set of supporting components 6 is provided at the lower part of each placement slot 12. In each placement slot 12, the arc openings of the pressing arc plate 52 and the supporting components 6 are opposite each other and the distance between them can be adjusted to accommodate perforating instruments of different diameters.
[0028] Reference Figure 2 and Figure 3 Each set of follower components 3 has the following structure: it includes a toothed column 31 and a worm gear 32. The worm gear 32 is located in the internal space of the side seat 11 and is fixedly connected to the bottom of the toothed column 31. The toothed column 31 can be partially exposed above the upper edge of the side seat 11.
[0029] The linkage component 4 has the following structure: a rotating shaft 41, a worm gear 42, and a gear disk 43. The rotating shaft 41, worm gear 42, and gear disk 43 are all located in the internal space of the side seat 11. The rotating shaft 41 is fitted in a bearing support inside the side seat 11 (rotational support can be achieved through the bearing). The worm gear 42 and gear disk 43 are both fixed on one side of the outer circular surface of the rotating shaft 41. The worm gear 42 is meshed with the worm 32.
[0030] Reference Figure 3 and Figure 4 The structure of the limiting mechanism 5 includes a hollow frame 51. The bottom of the frame 51 is fixedly connected to the top of the arc-shaped outer surface of the lower pressure plate 52. The frame 51 has multiple spaced tooth grooves on its vertical surface facing the toothed disc 43. The frame 51 is connected to the toothed disc 43 through these tooth grooves.
[0031] The internal vertical space of the frame 51 is called the middle groove 511. A limiting plate 13 is installed in the middle groove 511. The limiting plate 13 is fixed inside the side seat 11. When the frame 51 moves up and down, the limiting plate 13 in the middle groove 511 limits the frame 51 in the horizontal direction to prevent the frame 51 from shifting horizontally during the up and down movement.
[0032] Reference Figure 4 Anti-slip materials (such as anti-slip pads 521) are fixedly provided at equal intervals on the inner surface of the arc of the lower pressure plate 52. This design can increase the friction when the lower pressure plate 52 contacts the perforating instrument.
[0033] Reference Figure 5 and Figure 6 The structure of the supporting component 6 includes an upper supporting arc plate 61, which is fixedly installed at the lower circumference of the placement groove 12. Multiple sets of embedded sleeves are fixedly arranged axially at equal intervals in the middle position of the upper supporting arc plate 61. Multiple embedded grooves are spaced apart in each set of embedded sleeves, and an embedded seat 62 is installed in each embedded groove. Figure 5 The embodiment consists of three sets of embedded sleeves, each set of embedded sleeves having four embedded seats 62 installed.
[0034] Each embedded seat 62 has the following structure: a damping spring 621 is included, the fixed end of the damping spring 621 is fixedly connected to the inner wall of the embedded groove, the telescopic end of the damping spring 621 is connected upward to a limiting ring 622, and a ball bearing 623 is rotatably connected in the top slot of the limiting ring 622.
[0035] The working principle of this utility model is as follows: when the perforating instrument is inserted through the placement groove 12 before clamping, the ball bearing 623 located at the top of the inner seat 62 will support the perforating instrument and contact and rotate flexibly when the perforating instrument moves. This design makes the insertion of the perforating instrument smoother and reduces wear on the outer surface.
[0036] The process of using this utility model is as follows:
[0037] By using two sets of side seats 11 fixed on the base plate 1, when clamping and repairing the perforating instrument, the perforating instrument can be inserted sequentially through the two sets of placement slots 12, so that the position to be repaired is between the two sets of placement slots 12. Then, the forward and reverse motors 21 are started, and under the transmission of the track 22, the two sets of toothed columns 31 rotate synchronously in the same direction. This causes the worm 32 located at the bottom of the toothed column 31 to rotate synchronously and mesh with the worm wheel 42. As the worm wheel 42 drives the rotating shaft 41 to rotate, the toothed disc 43 located on one side of the rotating shaft 41 rotates synchronously and meshes with the tooth groove of the frame 51 to move downward until the lower pressure arc plate 52 at the bottom of the frame 51 completes the clamping work of the perforating instrument. This allows for the quick and stable clamping of perforating instruments of various sizes, thereby facilitating subsequent maintenance work.
[0038] Specifically, when the perforating instrument is inserted into the placement slot 12 before clamping, the ball bearing 623 located at the top of the insert 62 supports the perforating instrument and contacts and rotates synchronously as the perforating instrument moves. This design makes the insertion of the perforating instrument smoother and reduces wear on the outer surface. Furthermore, when the frame 51 moves the lower pressure plate 52 downward to complete the clamping of the perforating instrument, the ball bearing 623 is affected by the downward pressure of the lower pressure plate 52 and moves downward into the top slot of the insert 62. This design prevents the perforating instrument from becoming loose in the placement slot 12 due to the influence of the ball bearing 623 during clamping and maintenance. The bottom of the ball bearing 623 is equipped with a damping spring 621. After maintenance is completed, the lower pressure plate 52 will disengage from the top of the perforating instrument. At this time, the damping spring 621 will elastically reset and move the ball bearing 623 upward. Similarly, this facilitates the smooth extraction of the perforating instrument from the placement slot 12.

[0043] Then, using the aforementioned device, the forward and reverse motors 21 are started, and under the transmission action of the track 22, the two sets of toothed columns 31 rotate synchronously in the same direction. This causes the worm gear 32 located at the bottom of the toothed column 31 to rotate synchronously and mesh with the worm wheel 42. As the worm wheel 42 drives the rotating shaft 41 to rotate, the toothed disc 43 located on one side of the rotating shaft 41 rotates synchronously and meshes with the tooth groove of the frame 51 to move downward until the lower pressure arc plate 52 at the bottom of the frame 51 completes the clamping work of the perforating instrument.

[0048] Then, using the aforementioned device, the forward and reverse motors 21 are started, and under the transmission action of the track 22, the two sets of toothed columns 31 rotate synchronously in the same direction. This causes the worm gear 32 located at the bottom of the toothed column 31 to rotate synchronously and mesh with the worm wheel 42.

[0078] Based on the structure of Example 4, Example 8 further includes:
[0079] The linkage component 4 has the following structure: a rotating shaft 41, a worm gear 42, and a gear disk 43. The rotating shaft 41, worm gear 42, and gear disk 43 are all located in the internal space of the side seat 11. The rotating shaft 41 is fitted in a bearing support inside the side seat 11 (rotational support can be achieved through the bearing). The worm gear 42 and gear disk 43 are both fixed on one side of the outer circular surface of the rotating shaft 41. The worm gear 42 is meshed with the worm 32.
[0080] The structure of the limiting mechanism 5 includes a hollow frame 51. The bottom of the frame 51 is fixedly connected to the top of the arc-shaped outer surface of the lower pressure plate 52. The frame 51 has multiple spaced tooth grooves on its vertical surface facing the toothed disc 43. The frame 51 is connected to the toothed disc 43 through these tooth grooves.
[0081] The internal vertical space of the frame 51 is called the central groove 511, in which a limiting plate 13 is installed and fixed inside the side seat 11.
[0082] The structure of the support component 6 includes an upper support arc plate 61, which is fixedly installed at the lower circumference of the placement groove 12. Four sets of embedded seat sleeves are fixedly arranged at equal intervals along the axial direction at the middle position of the upper support arc plate 61. Each set of embedded seat sleeves is separated by four embedded grooves, and an embedded seat 62 is installed in each embedded groove.
[0083] Then, using the aforementioned device, the forward and reverse motors 21 are started, and under the transmission action of the track 22, the two sets of toothed columns 31 rotate synchronously in the same direction. This causes the worm gear 32 located at the bottom of the toothed column 31 to rotate synchronously and mesh with the worm wheel 42. As the worm wheel 42 drives the rotating shaft 41 to rotate, the toothed disc 43 located on one side of the rotating shaft 41 rotates synchronously and meshes with the tooth groove of the frame 51 to move downward until the lower pressure arc plate 52 at the bottom of the frame 51 completes the clamping work of the perforating instrument.
