Background
The pump performance test is an important link before a pump is pumped out, and is an important means for testing the mechanical performance (vibration, noise, bearing temperature and the like) and the hydraulic performance of the pump. When the pump is subjected to factory testing, an operator needs to butt-joint and install the pump head and a testing pipeline. For small-caliber pipelines, operators can directly and easily butt; for large-caliber or ultra-large-caliber pipelines, an operator needs to fit the pump body and the pipeline mounting hole to be aligned and fastened at the back. Due to the difference of the center heights of the pump bodies, the height and the height of a test pipeline need to be adjusted before butt joint and fastening, a gantry crane is adopted in a production workshop to adjust the pipeline under normal conditions, but the stroke of the gantry crane is not quantitative, and multiple operations are needed when the height of the pipeline is adjusted; on the other hand, the test pipeline applies force to the pump end due to self gravity, and the problems of large vibration and the like during pump test can be caused.

The utility model aims at realizing through the following technical scheme:
the utility model relates to a manual adjustable supporting device for erecting pipelines, which comprises a tray, a supporting rod, a hand wheel and a supporting seat;
the upper surface of the tray is a supporting surface, and the center of the lower surface of the tray is vertically and upwards provided with a prismatic blind hole;
the middle part of the hand wheel is vertically provided with a threaded connecting hole, and the lower end of the hand wheel is provided with an annular positioning table;
the side wall of the supporting rod is provided with a connecting thread matched with the threaded connecting hole in the middle of the hand wheel, the upper end part of the supporting rod is provided with a connecting platform the appearance of which is matched with the inner shape of the prismatic blind hole on the lower surface of the tray,
an annular supporting table is processed at the upper end of the supporting seat, an annular groove matched with the shape of an annular positioning table at the lower end of the hand wheel is processed on the annular supporting table, and a support rod abdicating cavity is formed downwards in the middle of the annular supporting table;
the hand wheel is installed on an annular supporting table at the upper end of the supporting seat through an annular positioning table at the lower end, so that the rotation axis of the hand wheel is positioned, the lower end of the supporting rod is screwed into a threaded connecting hole in the middle of the hand wheel, and the tray is supported at the upper end of the supporting rod through a prismatic blind hole at the lower surface.
The side wall of the support rod below the hand wheel is connected with a locking nut, after the support height of the tray is adjusted, the locking nut is rotated to the upper end face of the locking nut to tightly push against the lower surface of the hand wheel, and the hand wheel is prevented from loosening due to pressure action so as to prevent the pipeline height from deviating.
The anti-slip pad is arranged on the supporting surface of the tray, so that on one hand, the friction force between the tray and the supporting pipeline can be increased, the reliable supporting of the pipeline is ensured, on the other hand, the hard contact to the pipeline in use can be reduced, and the pipeline is protected.
When the test device is used, after the pump end is installed, the pipeline for the test is hoisted by the gantry crane, the supporting device is placed at the pipeline supporting position, the gantry crane is lowered to the lower end of the pipeline to be supported on the tray, and the sling chain is in a loose state. When the hand wheel is rotated, the static friction force between the pipeline and the tray is far greater than the rotation friction force when the hand wheel and the supporting rod are rotated by threads, so that the tray and the supporting rod do not rotate when the hand wheel rotates; the supporting rod lifts the tray and the supporting pipeline upwards under the action of rotation of the threads until the height of the axis of the pipeline meets the butt joint requirement.
Advantageous effects
The utility model discloses a supporting device, simple structure, convenient operation, low cost can realize supporting and the flexible and adjustable of support height to the effective regulation of test pump pipeline, and it is consuming time to have reduced the butt joint installation of the pump body and pipeline, has eliminated the big scheduling problem of test pump vibration that the pipeline arouses to the accepted force, can be effective, swift adjust well to the test pipeline.

FIG. 2 is a schematic view of the supporting device of the present invention;
in the figure, 1-tray, 2-support bar, 3-hand wheel, 4-support seat, 5-locking nut and 6-support device.
Detailed Description
The invention will be further described with reference to the accompanying drawings and examples.
Examples
The utility model relates to a manual adjustable supporting device for pipeline erection, as shown in figure 1, comprising a tray 1, a threaded supporting rod 2, a hand wheel 3, a supporting seat 4 and a locking nut 5;
the upper surface of the tray 1 is a supporting surface, and the center of the lower surface of the tray 1 is vertically and upwards provided with a prismatic blind hole;
the middle part of the hand wheel 3 is vertically provided with a threaded connecting hole, and the lower end of the hand wheel 3 is provided with an annular positioning table;
the side wall of the support rod 2 is provided with a connecting thread matched with the thread connecting hole in the middle of the hand wheel 3, the upper end part of the support rod 2 is provided with a connecting platform the appearance of which is matched with the inner shape of the prismatic blind hole on the lower surface of the tray 1,
an annular supporting table is processed at the upper end of the supporting seat 4, an annular groove matched with the shape of an annular positioning table at the lower end of the hand wheel 3 is processed on the annular supporting table, and a supporting rod abdicating cavity is formed downwards in the middle of the annular supporting table;
the hand wheel 3 is arranged on an annular supporting table at the upper end of the supporting seat 4 through an annular positioning table at the lower end, so that the rotating axis of the hand wheel 3 is positioned, the lower end thread of the supporting rod 2 is screwed into a threaded connecting hole in the middle of the hand wheel 3, and the tray 1 is supported at the upper end of the supporting rod 2 through a prismatic blind hole at the lower surface.
The side wall of the support rod 2 below the hand wheel 3 is connected with the locking nut 5, after the support height of the tray 1 is adjusted, the locking nut 5 is rotated to the upper end face to tightly push against the lower surface of the hand wheel 3, and the hand wheel 3 is prevented from loosening due to pressure action so as to prevent the pipeline height from deviating.
The anti-slip mat is arranged on the supporting surface of the tray 1, so that on one hand, the friction force between the tray 1 and the supporting pipeline can be increased, the reliable supporting of the pipeline is ensured, on the other hand, the hard contact to the pipeline in use can be reduced, and the pipeline is protected.
