Detailed Description
In the description of the present invention, it is to be understood that the terms "one end", "the other end", "outside", "upper", "inside", "horizontal", "coaxial", "central", "end", "length", "outer end", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, should not be construed as limiting the present invention.
The utility model will be further explained with reference to the drawings.
Referring to fig. 1-4, an auxiliary device for installing and welding a chemical pipeline includes two clamping mechanisms disposed oppositely, each of the clamping mechanisms includes a receiving base 1, two clamping jaws 2 respectively rotatably fitted to left and right ends of the receiving base 1, a screw rod 3 passing through the receiving base 1 and screwed with the receiving base 1, and a limiting base 4 rotatably connected to a lower end of the screw rod 3, the left and right sides of the limiting base 4 respectively have through holes 5 for the corresponding clamping jaws 2 to pass through, and the receiving bases 1 of the two clamping mechanisms are cooperatively connected to a connecting base 6.
With reference to fig. 3, the left and right sides of the limiting seat 4 are provided with U-shaped openings 7, the U-shaped openings 7 are provided with limiting pins 8, and the through holes 5 are formed between the U-shaped openings 7 and the limiting pins 8, that is, the clamping jaws 2 are prevented from being pulled out of the U-shaped openings 7 by the limiting pins 8. Wherein, the limit pin 8 is preferably a round pin.
With reference to fig. 1, the limiting seat 4 protrudes outwards, and the protruding portion is screwed with the first clamping rod 9.
With continued reference to fig. 1, the lower end of the clamping jaw 2 projects outwards, and a second clamping bar 10 is screwed onto the projecting part.
The first clamping bar 9 and the second clamping bar 10 are preferably both bolts.
Continuing to participate in fig. 2, the upper end of the screw rod 3 is connected with a handle 11 in a matching manner, and the handle 11 is convenient for a worker to rotate the screw rod 3.
Continuing to refer to fig. 4, the lower end of the screw 3 is provided with an annular groove 12, the lower end of the screw is inserted into the limiting seat 4, and a certain gap is formed between the screw 3 and the limiting seat 4, so that the screw 3 can rotate on the limiting seat 4, and because the limiting seat 4 is transversely inserted with a limiting bolt 13, the tail of the limiting bolt 13 is embedded into the annular groove 12 of the screw 3 but does not abut against the screw 3, so that the screw 3 cannot be loosened from the limiting seat 4.
