Description

Technical Field

[0001] The utility model relates to the field of pipeline processing, in particular to a pipeline clamping device. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. Usually, after the fluid is pressurized by a blower, compressor, pump and boiler, it flows from the high pressure part of the pipeline to the low pressure part. It can also be conveyed by the pressure of the fluid itself or gravity. Pipes are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. Before manufacturing and leaving the factory, most pipelines are produced on assembly lines, and most of the produced pipelines do not meet the standard length requirements. Therefore, in order to facilitate factory use, they need to be cut into sections or connected to meet the required length. In the existing cutting or connection, the pipeline is placed on a fixed processing platform, which makes it inconvenient to adjust the angle direction during cutting or connection, and requires a lot of manpower and time for auxiliary adjustment, resulting in an increase in production costs.

It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model, that is, the embodiments described are only part of the embodiments of the utility model, not all of the embodiments.

[0020] like Figure 1 As shown, a pipe clamping device is used to clamp the pipe and adjust the direction position during processing to facilitate extension or cutting. The pipe clamping device includes a clamping operation platform 1 in terms of specific structural design. A clamping mechanism for clamping and limiting the pipe is installed and connected on the clamping operation platform 1. The clamping mechanism is installed and connected on the horizontal connecting frame. The pipe is clamped and limited by the clamping mechanism. In addition, the horizontal connecting frame 2 is installed and connected to the clamping operation platform 1 through a movable mechanism.

[0021] Furthermore, in the embodiment, the pipe clamping device includes a clamping operation platform 1, on which a clamping mechanism for clamping and limiting the pipe is installed and connected; the clamping operation platform 1 is installed at the designated position of the design, so that the angle direction of the clamped pipe can be adjusted by cooperating with the clamping mechanism and the movable mechanism. Among them, the clamping mechanism includes a clamping finger cylinder 3, on which a clamping claw for clamping and limiting the pipe is installed and connected, and the top of the clamping finger cylinder 3 is connected to a connecting shaft 31 through an electric rotating table, and the end of the connecting shaft 31 away from the clamping finger cylinder 3 moves through the horizontal connecting frame 2 and the end is movable through the connecting piece and the output shaft of the first telescopic cylinder 4, and the clamping finger cylinder is driven to move up and down through the first telescopic cylinder 4; the horizontal connecting frame 2 is installed and connected to the clamping operation platform 1 through a movable mechanism. In implementation, the movable mechanism for controlling the angular direction adjustment of the horizontal connecting frame 2 includes a second telescopic cylinder 5, a driving rack 51, and a driving gear 52; the second telescopic cylinder 5 is fixedly installed and connected to the clamping operation platform 1, and the output shaft of the second telescopic cylinder 5 is connected to the driving rack 51 through a connecting plate, and the driving rack 51 is meshed with the driving gear 52. A rotating shaft is passed through the driving gear 52, and one end of the rotating shaft is rotatably connected to the clamping operation platform 1 through a bearing, and the other end of the rotating shaft is connected to the end of the horizontal connecting frame 2 away from the clamping finger cylinder 3, and a movable shaft is connected to the top of the end of the horizontal connecting frame 2 close to the driving gear 52, and the other end of the movable shaft is rotatably connected to the fixed top plate 6 through a bearing, and the fixed top plate 6 is fixed above the clamping operation platform through a fixing rod; a driving structure for driving the connecting shaft 31 on the horizontal connecting frame 2 to rotate is installed on the horizontal connecting frame 2. In this design, by controlling the "extension" of the output shaft of the second telescopic cylinder 5, the driving rack 51 is driven to "move" horizontally, so that the driving rack 51 drives the meshing driving gear 52 to rotate, thereby driving the rotating shaft connected to the driving gear 52 to rotate; and in order to ensure that the driving rack 51 can stably drive the driving gear 52 to rotate, a guide rail 53 is connected to the bottom end surface of the driving rack 51, and the driving rack 51 is slidably arranged with the clamping operation platform 1 through the guide rail 53. The horizontal connecting frame 2 rotatably connected to the clamping operation platform 1 is driven to rotate by controlling the rotating shaft connected to the driving gear 52, and then the clamping finger cylinder 3 is controlled to rotate to a suitable angular position by controlling the driving structure, so as to realize the control and adjustment of the angular position of the pipe held and limited by the clamping finger cylinder 3, so as to facilitate processing operations such as extension or cutting.

[0022] Further, in the embodiment, the drive structure of the arrangement includes a large pulley 21 and a small pulley 22; the large pulley 21 is rotatably connected to the end of the horizontal connecting frame 2 away from the clamping finger cylinder 3 through a rotating shaft, and one end of the rotating shaft connected to the large pulley 21 passes through one end of the horizontal connecting frame 2 and rotates through the bottom end of the horizontal connecting frame 2 and the end is connected to the output shaft of the servo motor, the servo motor is fixed on the horizontal connecting frame 2, and the other end of the rotating shaft rotates through the top end of the horizontal connecting frame 2 through a bearing; the small pulley 22 is connected to the end of the horizontal connecting frame 2 away from the large pulley 21 through a rotating shaft, and the large pulley 21 and the small pulley 22 are connected to the horizontal connecting frame 2 through a belt drive.

When the control is specifically implemented in this embodiment, the servo motor drives the small pulley 22 to rotate, so that the small pulley 22 drives the first telescopic cylinder 4 installed and connected to the horizontal connecting frame 2 to rotate together through the connecting sleeve 23, thereby driving the clamping finger cylinder 3 to rotate together with the output shaft of the first telescopic cylinder 4 through the connecting shaft 31 of the shaft connector, so as to adjust and control the pipe clamped by the clamping claw of the clamping finger cylinder 3 to rotate to a suitable angle position. It should be noted that since the clamping finger cylinder 3 is connected to the connecting shaft 31 through the electric rotating table, the angle position adjustment of the "precise angle" can be achieved through the electric rotating table alone, and the height position of the pipe clamped by the clamping finger cylinder 3 can be adjusted and controlled through the first telescopic cylinder 4 to ensure the quality of the "length or cutting and angle position of the extension or cutting". From the design of the entire pipe clamping device, the pipe clamping device can meet the angle position adjustment of pipe processing (extension or cutting), save time, improve the production efficiency of processing, and save costs.
