Description

Technical Field

[0001] The utility model relates to the technical field of gas, in particular to a butt joint fixture for PE gas pipes. Background Technique

[0002] As is well known, PE gas pipes are replacement products of traditional steel pipes and polyvinyl chloride gas. They have reliable connections, good stress cracking resistance, good low-temperature impact resistance, etc., and are commonly used pipes for modern gas pipeline installations. When installing gas pipes with larger existing hole diameters, due to their large overall volume and heavy weight, it is rather troublesome to operate when butt-jointing two gas pipes. Therefore, specific tools are required to achieve the butt joint of the two gas pipes.

[0003] In real life, the self-height of common PE gas pipe butt joint fixtures is fixed. For some already installed PE gas pipes, when repairing, in order to make the PE gas pipe butt joint fixture clamp the PE gas pipe, it is necessary to lay a backing plate at the bottom of the PE gas pipe butt joint fixture to increase its own height, so the practicability is not very good. Secondly, the inner diameters of the clamping plates of most PE gas pipe butt joint fixtures are fixed and cannot adjust their own inner diameters according to PE gas pipes of different diameters. Therefore, generally, only PE gas pipes of the same model can be clamped, so the practicability is not very good and there is still room for improvement. Content of the Utility Model

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4, a butt joint clamp for a PE gas pipe of the present utility model includes a base 1. Several hydraulic cylinders 2 are arranged on the upper part of the base 1. Fixed blocks 3 are arranged on the upper parts of several hydraulic cylinders 2. When the hydraulic cylinders 2 are started, the hydraulic cylinders 2 extend or contract, driving the fixed blocks 3 to move up and down, so as to adjust the height of the PE gas pipe butt joint clamp itself. A double-acting cylinder 4 is arranged between several fixed blocks 3. Several first fixing plates 5 are arranged between several double-acting cylinders 4. When the double-acting cylinder 4 is started, the double-acting cylinder 4 starts, driving several first fixing plates 5 on the right part to move. There is a gap between the lower parts of several first fixing plates 5 and the base 1 to prevent the first fixing plates 5 from rubbing against the base 1 when moving. Threaded holes are arranged at both ends of several first fixing plates 5, and first bolts 6 are threadedly connected thereto. Second fixing plates 7 are threadedly connected to the upper parts of several first bolts 6. Through the threaded connection mode of the first bolts 6 and the threaded holes, the second fixing plates 7 and the first fixing plates 5 are installed together. Threaded holes 8 are arranged at one ends of several first fixing plates 5 and the second fixing plates 7. A first clamping device is installed between several first fixing plates 5 and the second fixing plates 7. According to the diameter of the PE gas pipe to be clamped, the first clamping device is installed or not installed. Only the cooperation of the first fixing plates 5 and the second fixing plates 7 is needed to clamp the PE gas pipe with the corresponding diameter. The first clamping device includes several second bolts 9, which are all threadedly connected to the corresponding threaded holes 8. Second clamping plates 10 are threadedly connected to one ends of several second bolts 9. By screwing the second bolts 9 into the threaded holes 8 of the first fixing plates 5 and the second fixing plates 7, several second clamping plates 10 can be installed on the first fixing plates 5 and the second fixing plates 7, so that several second clamping plates 10 clamp the PE gas pipe with the corresponding diameter. Several second support rods 11 are arranged at one ends of several second clamping plates 10. One ends of several second support rods 11 are all in contact with the end faces of the first fixing plates 5 or the second fixing plates 7. The second support rods 11 support on the first fixing plates 5 or the second fixing plates 7, playing a supporting role. A second clamping device is installed between several first fixing plates 5 and the second fixing plates 7. According to the diameter of the PE gas pipe to be clamped, the second clamping device is installed or not installed. The second clamping device includes several third bolts 12, which are all threadedly connected to the corresponding threaded holes 8. Third clamping plates 13 are threadedly connected to one ends of several third bolts 12. By screwing the third bolts 12 into the threaded holes 8 of the first fixing plates 5 and the second fixing plates 7, several third clamping plates 13 can be installed on the first fixing plates 5 and the second fixing plates 7, so that several third clamping plates 13 clamp the PE gas pipe with the corresponding diameter. Several third support rods 14 are arranged at one ends of several third clamping plates 13. One ends of several third support rods 14 are all in contact with the end faces of the first fixing plates 5 or the second fixing plates 7. The third support rods 14 support on the first fixing plates 5 or the second fixing plates 7, playing a supporting role.

[0024] In summary, when using the PE gas pipe docking fixture, the staff places the PE gas pipe docking fixture under the two PE gas pipes to be docked. According to the diameter of the PE gas pipe to be docked, the second bolt 9 or the third bolt 12 can be threadedly connected to the second threaded hole 8 on the first fixing plate 5 and the second fixing plate 7 respectively by means of threaded connection, and the second clamping plate 10 or the third clamping plate 13 is installed on the first fixing plate 5 and the second fixing plate 7. Then, the hydraulic cylinder 2 is started. The hydraulic cylinder 2 extends, driving the first fixing plate 5 and the installed second clamping plate 10 or the third clamping plate 13 to move upward until the second clamping plate 10 or the third clamping plate 13 fits against the bottom side wall of the PE gas pipe. After that, the second fixing plate 7 is installed together with the first bolt 6 and the threaded connection of the first threaded hole. At this time, the PE gas pipe is clamped.
