technical field

The utility model relates to the technical field of hydropower construction, in particular to an auxiliary marking tool for hydropower pipelines.

Background technique

In the process of hydropower construction, it is usually necessary to cut the pipe to meet the requirements of the installation design. When cutting the pipe, it is usually necessary to first assist in marking the outer surface of the pipe, so as not to cut improperly and affect the straightness of the nozzle, thus giving Subsequent construction will leave hidden dangers. In the existing operations, most of the construction workers use a measuring ruler to measure the cutting length, and then use a marking tool to auxiliary mark a small section at the corresponding position of the pipeline for the convenience of operation, and then use the cutting tool to cut. Although the method is simple and quick, but the accuracy is low, because the marking is usually not along the circumference of the pipe, and the freehand marking is prone to deflection, so there will be a large error after cutting, especially when used for water pipes at the interface. If the end is not cut well, water leakage and water seepage will easily occur, which will affect the construction quality.

Detailed ways

The utility model will be described clearly and completely below in conjunction with accompanying drawing and embodiment:

As shown in Figures 1 to 3, an auxiliary marking tool for hydropower pipelines according to the utility model includes a support frame 1, which is preferably set in an arc-shaped structure, so as to ensure its accommodation space while reducing the impact on the Occupation of external space, so as to avoid the phenomenon that the rotation of the support frame 1 is hindered during use; the bottom of the support frame 1 is provided with a support seat 2, and the support seat 2 is preferably set in a U-shaped structure, and the support seat 2 is rotated inside and provided with a support roller 3 , two sets of support rollers 3 are arranged in parallel to ensure the contact surface with the pipeline, and ensure the stability of the entire tool when it is in use along the outer circumference of the pipeline; the upper part of the support frame 1 is provided with an adjustment rod 4, and the adjustment rod 4 can be adjusted Adjust the distance between it and the support seat 2 along the support frame 1, so as to meet the marking operation for pipes with different diameters, and expand the scope of application of the present utility model; There are two, which are distributed at both ends of the adjustment rod 4. There is a mounting seat between the two limit rollers 5, and a marking tool 6 is detachably placed in the mounting seat; the marking tool 6 can be a marking pen or a pointed tip according to requirements. metal pole. The mounting seat is preferably a mounting sleeve 7 that runs through the two rollers. One side of the mounting sleeve 7 is threaded with a locking screw 8 for fixing the marking tool 6 placed therein. At the same time, by turning the locking screw 8, the length of the marking tool 6 protruding from the installation sleeve 7 can also be adjusted to meet the needs of different types of marking tools 6.

Further, the adjustment rod 4 is a threaded rod, the top of the support frame 1 is provided with a threaded hole, and the adjustment rod 4 is connected with the support frame 1 through threaded rotation; sex. In addition, the adjustment rod 4 and the limit roller 5 are preferably connected by rotation, so that the limit roller 5 can be adjusted to a state parallel to the support roller 3, so as not to adjust the limit roller 5 and the support roller 3 when the adjustment rod 4 is rotated. When adjusting the distance between the limit roller 5 and the surface of the pipe, the limit roller 5 is in a state perpendicular to the support roller 3. At this time, the reverse rotation of the adjustment lever 4 will cause the limit roller 5 to break away from the pipe surface. , the forward rotation of the adjustment lever 4 will cause the limit roller 5 to be pressed against the surface of the pipeline and cannot rotate around the surface of the pipeline.

Further, two limit rollers 5 are rotatably arranged on both sides of the bottom end of the connecting rod 10, the connecting rod 10 is connected with the adjusting rod 4 in rotation, and the bottom end of the adjusting rod 4 is provided with a limit sleeve which can only move along its length direction. Cylinder 11, the bottom of the limit sleeve 11 protrudes along the circumferential direction with a number of limit teeth 12, the connecting rod 10 is fixed with a positioning cylinder 13, and the positioning cylinder 13 is provided with a limit groove that matches and engages with the limit teeth 12 14. The engagement setting between the positioning cylinder 13 and the limit sleeve 11 can limit the adjustment rod 4 and the connecting rod 10 after the limit roller 5 is in contact with the pipeline and adjusted to be parallel to the support roller 3, so as to prevent the When the marking work is carried out, the limit roller 5 is deflected due to the rotation of the connecting rod 10 relative to the adjustment rod 4, so as to ensure that the marking work is carried out normally; the limit sleeve 11 can only move along the vertical direction of the adjustment rod 4, It can ensure that the limit sleeve 11 can rotate synchronously with the rotation of the adjustment rod 4, so that when the limit tooth 12 on the limit sleeve 11 is engaged with the limit groove 14 on the positioning cylinder 13, the connecting rod 10 and the adjustment rod 4 will not rotate relative to each other, thereby avoiding the situation that the limit roller 5 will not be deflected due to the rotation of the connecting rod 10 relative to the adjusting rod 4 when the marking work is carried out.

The vertical movement of the limit sleeve 11 relative to the adjustment rod 4 can adopt the method of setting a limit block inside the limit sleeve 11, and setting a limit groove 14 at both ends of the adjustment rod 4; it can also be carried out in other ways. What adopt among the example is to vertically set limit bar 15 on one side of adjusting bar 4 bottoms, vertically be provided with adjusting groove 16 on the limit sleeve 11, and the length of adjusting groove 16 is greater than the diameter of limit bar 15; When the sleeve 11 is positioned and connected with the positioning cylinder 13, the limit rod 15 is located at the top of the adjustment groove 16. When the relative position of the connecting rod 10 and the adjustment rod 4 needs to be adjusted, the limit sleeve 11 is pulled up, and the adjustment groove 16 will move along the The limit rod 15 moves upwards, and now the limit tooth 12 disengages from the limit groove 14, and the rotation operation between the connecting rod 10 and the adjusting rod 4 can be realized. The structure is simple, the operation is convenient and the practicability is strong.

When the utility model is in use, firstly, the tool is set outside the pipeline from one side of the pipeline, so that the support roller 3 at the bottom is in contact with the bottom surface of the pipeline, and then the adjusting rod 4 is turned to make the limit roller 5 contact with the surface of the pipeline. The roller 5 is kept parallel to the support roller 3. After the limit roller 5 contacts the surface of the pipeline, the limit sleeve 11 can be pulled up to release the restriction between the connecting rod 10 and the adjusting rod 4. At this time, the connecting rod 10 can be rotated. Just make the limit roller 5 parallel to the support roller 3; then move the limit sleeve 11 in a direction so that it is connected and positioned with the positioning cylinder 13, so that when the mark is rotated, the moving roller will move due to the rotation of the connecting rod 10 relative to the adjustment rod 4. In case of deflection, ensure the normal operation of the marking work. This tool can be used to mark along the surface of the pipe, increasing the marking area, improving the accuracy of marking, and providing a solid foundation for subsequent precise cutting.
