Problems solved by technology

During the maintenance and replacement of water meters, especially in winter, there are mainly the following problems. First, the dial of the water meter is easy to freeze and crack, causing frequent injuries to maintenance personnel. Simple protective equipment can no longer meet the actual work needs; The construction is difficult due to the environment. The water meter well is covered by accumulated water, and repairing the meter is groping in the cold water. Not only is it difficult to maintain, but it will also cause certain damage to the body of the staff. Third, the water meters used now are all rotors. The rotor-type water meter and the rotor-type water meter are suitable for the measurement of the total amount of one-way water flow in small-diameter pipes. It was found that due to the accumulation of water in the pipeline well or the large distance from the ground, it was difficult to operate, time-consuming and labor-intensive, and the work efficiency was extremely low. Moreover, there was no corresponding special tool, and there was a potential safety hazard of falling tools. manpower and time

Embodiment 1

[0029] Such as Figure 1-Figure 4 As shown, the special-shaped wrench for water meter disassembly and assembly of the present invention includes a wrench handle 1 welded by round steel pipes, a connecting rod 2 and a wrench head 5 made of steel, and the wrench handle 1 is connected to one end of the connecting rod 2. The connection between the wrench handle 1 and the connecting rod 2 is fixed by a fastening bolt 6, the other end of the connecting rod 2 is provided with a fixed screw 3, and the fixed screw 3 is connected to the wrench head 5 and fixed by the fixing nut 4, and the wrench head 5 is Dial wrench.

[0030] The wrench handle 1 has a T-shaped structure, and an anti-slip protrusion 25 is arranged on the horizontal handle of the T-shaped structure. The longitudinal handle of the T-shaped structure is connected to one end of the connecting rod 2, and the length of the connecting rod 2 is 700mm-800mm. The rod 2 is set as two sections, and the length of each link is 400mm...

Embodiment 2

[0034] Such as Figure 5 As shown, on the basis of Embodiment 1, the wrench head 5 is a master valve wrench, and the said master valve wrench includes a mounting plate II12, one end of the mounting plate II12 is provided with a mounting slot II, and the other end of the mounting plate II12 is One end is connected with a square groove wrench head 13, and the square groove wrench head 13 is welded end to end by four pieces of square steel with the same structure and size.

[0035] When in use, just clamp the square groove wrench head 13 directly on the main valve. The square groove wrench head 13 can completely match the main valve, and the contact depth between the wrench head and the main valve is moderate. After the fixing is completed, you only need to turn the wrench handle 1 It can facilitate the disassembly and installation of the main valve.

Embodiment 3

[0037] Such as Figure 6 As shown, on the basis of Example 1, the wrench head 5 is a water meter union wrench, and the water meter union wrench includes a mounting plate III15, one end of the mounting plate III15 is provided with a mounting slot III16, and the mounting plate III15 The other end of the U-shaped groove wrench head 14 is connected.

[0038] When in use, clamp the U-groove wrench head 14 on the joints at both ends of the water meter. After fixing, move the wrench handle 1 and connecting rod 2 back and forth to complete the connection and disassembly of the water meter joints. The U-shaped groove wrench head 14 It can cooperate with the union of the water meter, which reduces the frequency of dismantling the union and shortens the time for disassembly and assembly.
