Measuring combination tool for prefabrication installation of pipeline

[0046] Example 1

[0047] Such as Figure 1 to Figure 15 As shown, the measuring combination tool for prefabricated installation of the measuring pipeline of this patent includes a first straight ruler or a right angle ruler 1, a second straight ruler or a right angle ruler 2, an upper rotating body, and a lower rotating body.

[0048] Among them, the upper rotating body includes an upper gland, an upper rotating disk 10, a rotating table 6, and four upper fixing bolts; wherein, the upper gland is a circular metal block with upper positioning holes 3 and four upper fixing circular holes 5 The upper rotating disk 10 is a circular metal block, the upper surface of the upper rotating disk 10 is provided with a first through chute 11, 4 upper fixing bolt holes, and a lower positioning hole 4 corresponding to the upper positioning hole 3 at the center position of the upper surface of the upper rotating disk 10; The positioning hole 3 and the lower positioning hole 4 are bolt holes; the upper fixing bolt hole corresponds to the upper fixing round hole 5 of the upper gland, the upper positioning hole 3 is set at the corresponding position of the first through chute 11, and the upper positioning bolt 13 is set In the upper positioning hole 3 and the lower positioning hole 4; 4 upper fixing bolts pass through the upper fixing round hole 5 and the upper fixing bolt hole to tightly fix the upper gland and the upper rotating disk 10 together, so that the upper surface of the upper rotating disk 10 There is no gap contact with the lower surface of the upper gland; the upper positioning bolt 13 locates the relative position of the upper rotating body and the lower rotating body through the upper positioning hole 3 and the lower positioning hole 4.

[0049] The lower surface of the upper rotating disk 10 is provided with a rotating table 6 whose lower diameter is larger than the upper diameter; the height of the rotating table 6 is consistent with the thickness of the lower sliding disk 16. The rotating table 6 set on the upper rotating disc 10 is a stepped structure, the upper part is a cylinder, and the lower part is a round table with a larger diameter than the cylinder; the circular hole of the lower sliding disc 16 is a stepped round hole, and the diameter of the upper part of the circular hole corresponds to The diameter of the lower part of the platform 6 corresponds to each other, and the diameter of the lower part of the circular hole corresponds to the diameter of the lower part of the rotating platform 6, and both are tightly fitted.

[0050] The lower rotating body includes a lower gland 15, a lower sliding plate 16, a lower fixing bolt, and a lower positioning bolt 25.

[0051] Among them, the lower sliding plate 16 is a split circular metal block composed of two symmetrical semicircular metal blocks, and the center is provided with a circular limiting hole 24 whose lower diameter is larger than the upper diameter; the upper diameter of the circular limiting hole 24 and the rotation The upper diameters of the table 6 correspond to each other so that the rotating table 6 is tightly fitted with the circular limiting hole 24, and the lower diameter of the circular limiting hole 24 is opposite to the lower diameter of the rotating table 6; the two semicircular metal blocks are respectively Set two lower sliding plate fixing bolt holes 19. The matching tolerance of the rotating table 6 and the circular limiting hole 24 is 0.02mm.

[0052] The lower gland 15 is a circular metal block. The left and right sides of the lower gland 15 are respectively provided with two lower gland round holes 20 corresponding to the lower sliding plate fixing bolt holes 19; the center of the lower gland 15 has a lower positioning bolt Hole 21, the lower positioning bolt 25 is set in the lower positioning bolt hole 21, and the thread length of the lower positioning bolt 25 is greater than the depth of the lower positioning bolt hole 21 by 3-10mm; the upper surface center of the lower gland 15 is provided with a passage through the lower gland 15 second through chute 22 at the center of the circle; the lower fixing bolt passes through the fixing bolt hole of the lower sliding disc 16 and the lower gland round hole 20 to tightly fix the lower gland 15, the lower sliding disc 16 together, so that the lower sliding disc 16 The lower surface is in seamless contact with the upper surface of the lower gland 15. The center of the upper surface of the lower gland 15 is also provided with a third through chute, the third through chute and the second through chute 22 cross; the depth of the third through chute is twice the depth of the second through chute 22 .

[0053] The first straight ruler or the square ruler 1 is arranged in the first through chute 11 or the second through chute 22.

[0054] The second ruler or square ruler 2 is arranged in the second through chute 22.

[0055] If necessary, an angle value is engraved on the upper surface of the upper gland and the circumferential direction, and an angle value is engraved on the circumferential direction of the upper rotating disk 10.

[0056] The depth of the first through chute 11 of the rotating disk is greater than the thickness of the first straight ruler or the square ruler 1, the second ruler or the square ruler 2, the third ruler or the square ruler. The depth of the second through chute 22 of the lower gland 15 is greater than the thickness of the first straight ruler or the square ruler 1, the second ruler or the square ruler 2, the third ruler or the square ruler.

[0057] The upper rotating body and the lower rotating body have the same diameter. Threads are provided in various bolt holes. A thread can be provided in the round hole.
