[0038] Example

[0039] like Figure 1 and Figure 2 As shown, Figure 1 Schematic diagram of the structure of the pipe clamping device; Figure 2 This is a schematic diagram illustrating the connection between the mounting frame and the clamping mechanism. Specifically, this embodiment provides a pipe clamping device comprising a support plate 1, a mounting frame 3, a clamping mechanism, a rotating mechanism, and a lifting mechanism. The mounting frame 3 is rotatably connected to the support plate 1. A rotating mechanism is provided on one side of the support plate 1 to drive the mounting frame 3 to rotate. The mounting frame 3 is provided with a clamping mechanism and a lifting mechanism to drive the clamping mechanism upward.

[0040] Among them, a first rotating shaft 2 is provided on the support plate 1, and an installation cavity is provided in the support plate 1. One end of the first rotating shaft 2 passes through the top wall of the support plate 1 and is inserted into the installation cavity, and is rotatably connected to the support plate 1, and the other end is fixedly connected to the mounting frame 3.

[0041] A driven bevel gear 18 is fixedly connected to the first rotating shaft 2, and a rotating mechanism is also provided on the support plate 1, which includes a second rotating shaft 17, a driving bevel gear 10 and a turntable 19. One end of the second rotating shaft 17 is provided with the driving bevel gear 10, and the driving bevel gear 10 is meshed with the driven bevel gear 18. The other end of the second rotating shaft 17 passes through the side wall of the support plate 1 and is fixedly connected to the turntable 19. A handle is provided on the turntable 19, and the handle is rotated by external force to rotate the turntable 19. The turntable 19 drives the second rotating shaft 17 to rotate, and the second rotating shaft 17 drives the driving bevel gear 10 to rotate. The driving bevel gear 10 cooperates with the driven bevel gear 18, thereby driving the first rotating shaft 2 to rotate, and then the first rotating shaft 2 drives the mounting bracket 3 to rotate.

[0042] In which, the mounting frame 3 includes a frame 301 and a top plate 302, the frame 301 is fixedly connected to the end of the first rotating shaft 2 away from the support plate 1, and the clamping mechanism is slidably connected inside the frame 301; the top plate 302 is fixedly connected to the side of the frame 301 away from the first rotating shaft 2, that is, the top plate 302 is fixedly connected to the top of the frame 301.

[0043] The mounting frame 3 is provided with a lifting mechanism for driving the clamping mechanism to move up and down along the height direction of the frame 301. The lifting mechanism includes a telescopic oil cylinder or a telescopic air cylinder, which drives the clamping mechanism to move up and down within the frame 301. Alternatively, the lifting mechanism includes a first driving member 5, a reel 7, a guide wheel 9, and a connecting rope 8. The first driving member 5 is disposed at the top of the top plate 302. The bottom end of the first driving member 5 is rotatably connected to an output shaft 6. The end of the output shaft 6, which is away from the first driving member 5, passes through the top plate 302 and is fixedly connected to the reel 7. The guide wheel 9 is fixedly connected to the bottom end of the top plate 302 and is located on one side of the reel 7. One end of the connecting rope 8 is wrapped around the reel 7, and the other end is wrapped around the guide wheel 9 and connected to the clamping mechanism. The first driving member 5 drives the output shaft 6 to rotate, driving the reel 7 to reel in and out the connecting rope 8. When the reel 7 is reeled in, the connecting rope 8 pulls the clamping mechanism upward, causing it to rise within the frame 301. When the reel 7 is unreeled, the clamping mechanism slides downward within the frame 301 under the action of gravity, thereby adjusting its height. It should be noted that the first driving member 5 includes a motor.

[0044] Specifically, the clamping mechanism includes a slider 4 and a set of clamping elements corresponding to the slider 4, or two sets of clamping elements arranged in parallel along the length of the pipe. In this embodiment, the clamping mechanism can adopt any of the structural arrangements. The slider 4 is connected to the end of the connecting rope 8 away from the reel 7 and is clamped by the two sides of the frame 301. The clamping elements include a movable plate, a second driving member 12, and two clamping blocks 15. The slider 4 is provided with two parallel chute 21. Each chute 21 is provided with a telescopic member 22. One end of the telescopic member 22 is fixedly connected to the side wall of the chute 21, and the other end is fixedly connected to one end of a slide rod 11. The end of the slide rod 11 away from the telescopic member 22 is fixedly connected to the movable plate. The two telescopic members 22 drive the movable plates of the two sets of clamping elements to move toward or against each other, thereby adjusting the spacing between the two sets of clamping elements and flexibly adapting to the length of the pipe. It should be noted that the telescopic member 22 includes an electric telescopic rod. Of course, it should be understood that the telescopic member 22 can also be other telescopic structures besides the electric telescopic rod when meeting actual needs, which is not limited in this embodiment.

[0045] like Figure 3 As shown, Figure 3The diagram is a schematic diagram of the connection between the drive assembly and the mounting plate. The drive assembly includes a second drive member 12, a bidirectional threaded rod 23, two connecting blocks 13 and two connecting rods 14. The bidirectional threaded rod 23 arranged along the height direction of the movable plate is rotatably connected in the movable plate. The bidirectional threaded rod 23 is provided with two symmetrical connecting blocks 13. The bidirectional threaded rod 23 includes a first thread segment and a second thread segment with opposite thread directions. One of the connecting blocks 13 is threadedly connected to the first thread segment, and the other connecting block 13 is threadedly connected to the second thread segment. One side of each of the two connecting blocks 13 is fixedly connected to the connecting rod 14. The end of the connecting rod 14 away from the connecting block 13 is fixedly connected to the clamping block 15. The top of the movable plate is provided with a second drive member 12, which is rotatably connected to the bidirectional threaded rod 23. The second drive member 12 is similar to the first drive member 5 and includes a motor. No further description is given in this embodiment. The bidirectional threaded rod 23 is driven to rotate by the second driving member 12, driving the two connecting blocks 13 on the bidirectional threaded rod 23 to move toward or in opposite directions, thereby driving the two clamping blocks 15 to move toward or in opposite directions on the movable plate.

[0046] As a further improved technical solution of this embodiment, a groove is provided on one side of the two clamping blocks 15. Specifically, the two grooves are arranged opposite to each other and are both semicircular grooves. When the two-way threaded rod 23 drives the two clamping blocks 15 to move toward each other on the movable plate, the two clamping blocks 15 are in contact with each other, thereby preliminarily clamping the pipe. A plurality of telescopic units 20 arranged along the arc direction are provided in the groove. A clamping plate 16 is provided at one end of the telescopic unit 20 away from the clamping block 15, which is used to contact the side wall of the pipe, thereby reinforcing the stability of the pipe placement. It should be noted that the telescopic unit 20 is similar to the telescopic member 22. The telescopic unit 20 includes an electric telescopic rod, which will not be described in detail in this embodiment.

[0047] In order to prevent the telescopic unit 20 from continuing to extend after the clamping plate 16 on the telescopic unit 20 contacts the side wall of the pipe, thereby ultimately damaging the telescopic unit 20, a pressure sensor is provided on the clamping plate 16 of the two clamping blocks 15 on the movable plate, the clamping block 15 closer to the second driving member 12, that is, the clamping block 15 located at the upper end, for sensing the pressure generated when the telescopic unit 20 drives the clamping plate 16 to contact the side wall of the pipe.

[0048] like Figure 4 As shown, Figure 4The diagram is a block diagram of the telescopic unit. Specifically, the pipe clamping device further includes a controller electrically connected to the pressure sensor and the telescopic unit 20. When the pressure sensor senses a pressure signal, it converts the pressure signal into an electrical signal and transmits it to the controller. The controller then sends a stop signal to the telescopic unit 20. Upon receiving the stop signal from the controller, the telescopic unit 20 stops extending the pipe sidewall, thereby preventing damage to the telescopic unit 20. The controller can be any conventional controller, as long as it meets practical needs, and is not limited to a specific model in this embodiment.

[0049] Specifically, the pipe clamping device provided in this embodiment has the following working principles:

[0050] When installing and positioning the pipeline, the sliding rod 11 is driven to slide by the telescopic member 22, thereby adjusting the position of the two mounting plates according to the length of the pipeline; the pipeline is placed on the two clamping blocks 15 at the bottom, and the bidirectional threaded rod 23 is driven to rotate by the second driving member 12, driving the two connecting blocks 13 to move toward each other on the bidirectional threaded rod 23, thereby driving the two clamping blocks 15 to move toward each other, and then performing preliminary positioning of the two ends of the pipeline; the clamping plate 16 is then driven to move by the telescopic unit 20 until it contacts the side wall of the pipeline. When the pressure sensor senses the pressure generated when the clamping plate 16 contacts the side wall of the pipeline, the controller sends a stop signal to the telescopic unit 20, and the telescopic unit 20 stops pushing the side wall of the pipeline to extend, preventing the telescopic unit 20 from extending. Unit 20 is damaged, and the stability of pipeline placement is also improved; when the reel 7 is reeled, the connecting rope 8 pulls the clamping mechanism upward, and the clamping mechanism rises in the frame 301; when the reel 7 is unreeled, the clamping mechanism slides downward in the frame 301 under the action of gravity, thereby adjusting the height of the pipeline on the clamping mechanism; by rotating the turntable 19, the second rotating shaft 17 drives the active bevel gear 10 to rotate, and the active bevel gear 10 engages with the driven bevel gear 18, thereby driving the first rotating shaft 2 fixedly connected to the driven bevel gear 18 to rotate, and then drives the mounting frame 3 to rotate, and drives the clamping mechanism to rotate with the mounting frame 3 to adjust the direction of the pipeline on the clamping mechanism, which is beneficial to the installation of the pipeline and has high flexibility.

[0051] Specifically, the pipe clamping device provided in this embodiment has at least the following beneficial effects:

[0052] (1) The two ends of the pipe are clamped up and down by the clamping block 15, and then the side wall of the pipe is abutted by a number of telescopic units 20 in the groove, so that it is suitable for clamping pipes of different diameters, thereby improving the stability of pipes of different diameters during transportation;

[0053] (2) The clamping mechanism is driven to rise in the frame 301 by the lifting mechanism, and the pipe clamped by the clamping mechanism also rises accordingly, thereby adjusting the height of the pipe;

[0054] (3) The mounting bracket 3 on the first rotating shaft 2 is driven to rotate by the rotating mechanism, and the pipe clamped by the clamping mechanism will also rotate with the rotation of the mounting bracket 3, thereby adjusting the direction of the pipe, which is beneficial to the installation of the pipe and has high flexibility.

[0055] The present application provides a pipe clamping device, comprising a support plate 1, a mounting frame 3, and a clamping mechanism, wherein the mounting frame 3 is movably connected to the support plate 1; the clamping mechanism comprises a slider 4 and a group of clamping members corresponding to the slider 4, or at least two groups of clamping members arranged in parallel along the length of the pipe; the slider 4 is movably connected to the mounting frame 3; the clamping members comprise a movable plate and a clamping block 15, wherein the movable plate is movably connected to the slider 4, and at least two clamping blocks 15 are movably connected to the movable plate, wherein the inner wall of the clamping block 15 is provided with a plurality of telescopic units 20 for abutting the side wall of the pipe. The present application clamps the pipe up and down by using the clamping blocks 15, and then abuts the side wall of the pipe by using the plurality of telescopic units 20 on the inner wall of the clamping block 15. Thus, the device is suitable for clamping pipes of different diameters, thereby improving the stability of pipes of different diameters during transportation.
