Abstract
The utility model relates to a universal wrench for quickly disassembling and assembling end cap nuts of a water supply pump of a thermal power plant. At present, the cap nut of the water feeding pump end cap has large weight and large size, and a worker is very labor-intensive (if the whole process is carried out by using a special hydraulic wrench, the time is very long) and usually two persons replace and finish 1 nut for 20 minutes. A general spanner for quickly disassembling and assembling end cap nuts of water supply pumps of thermal power plants is characterized in that a circular ring (1) and Z-shaped thin steel pipes (2) are fixedly connected, the annular surface of the circular ring is fixedly connected with the Z-shaped thin steel pipes, 3 phi 10 top thread holes (3) are uniformly formed in the annular surface of the circular ring at 120 degrees, top threads (4) are screwed in each top thread hole, and locking nuts (5) are screwed in the top threads. A rotary sleeve (6) is arranged at the hand-held position of the Z-shaped thin steel pipe. The utility model is applied to a wrench for dismantling the end cover of the water pump.
Description
Technical Field
The utility model relates to a universal wrench for quickly disassembling and assembling end cap nuts of a water supply pump of a thermal power plant.
Background
At present, the cap nut of the water feeding pump end cap has large weight and large size, and a worker is very labor-intensive (if the whole process is carried out by using a special hydraulic wrench, the time is very long) and usually two persons replace and finish 1 nut for 20 minutes.
Disclosure of Invention
The utility model aims to provide a universal wrench for quickly disassembling and assembling nuts of a water supply pump end cover of a thermal power plant, which greatly increases the efficiency of disassembling and assembling the nuts after being used, and can finish the rotation work when one nut is disassembled and assembled within 3 minutes after being operated by 1 person.
The above object is achieved by the following technical scheme:
the utility model provides a thermal power plant's feed pump end cover nut quick assembly disassembly universal wrench, ring and Z type thin steel pipe, the annular face of ring with Z type thin steel pipe fixed connection, the annular face of ring on be 120 degrees even and offered 3 phi 10's top silk hole, every top silk downthehole screw in has the jackscrew, the jackscrew on screw in have lock nut.
The universal wrench for quickly disassembling and assembling the end cap nut of the water supply pump of the thermal power plant is characterized in that the ring adopts a steel ring structure with the inner diameter of 120mm, the outer diameter of 160mm and the thickness of 50 mm.
The universal wrench for quickly disassembling and assembling end cap nuts of water supply pumps of thermal power plants is characterized in that a rotary sleeve is arranged at the hand-held position of the Z-shaped thin steel tube
The utility model has the beneficial effects that:
1. the utility model provides a quick disassembly universal wrench for the end cap nut of the water supply pump of a thermal power plant, which is simple in structure, light and convenient, capable of being applicable to nuts of different sizes, improving maintenance efficiency, safe and reliable, and aims to assist maintenance personnel to quickly disassemble and assemble the nut by screwing the nut into a stud after the tightening force of the end cap nut of the water supply pump is released under the operation of a heavy hydraulic wrench or at the initial stage of reinstallation.
2. The wrench and hexagonal nut matching main body is a circular ring with the inner diameter of 120mm, the outer diameter of 160mm and the thickness of 50mm, the circular ring is equally divided into 3 phi 10 top thread holes, and 3 top threads with locking nuts are arranged to adjust the size of the wrench corresponding to the nut of the end cover of the water feeding pump. The end face of the spanner is welded with the Z-shaped thin steel pipe, so that the spanner increases the rotation moment, the rotation sleeve is increased with the holding position of the spanner, and the friction between the hand of an operator and the sleeve does not occur during working.
Drawings
Fig. 1 is a schematic diagram of the structure of the present utility model.
Fig. 2 is a left side view of fig. 1.
In the figure: 1. the device comprises a circular ring, 2Z-shaped thin steel pipes, 3 jackscrew holes, 4 jackscrews, 5 locking nuts, 6 and a rotary sleeve.
Detailed Description
Examples
The utility model provides a thermal power plant's feed pump end cover nut quick assembly disassembly universal wrench, ring 1 and Z type thin steel pipe 2, the annular face of ring with Z type thin steel pipe fixed connection, the annular face of ring on be 120 degrees even top silk hole 3 of having seted up 3 phi 10, every top silk downthehole screw in has jackscrew 4, the screw in have lock nut 5. The inner diameter of the circular ring is 120mm, the outer diameter of the circular ring is 160mm, and the thickness of the circular ring is 50 mm. One end of the Z-shaped thin steel pipe is fixedly connected with one side of the circular ring into an integrated structure in a welding mode, and the circular ring is driven to rotate through the Z-shaped thin steel pipe. The three top thread holes have the same aperture, and each aperture is internally screwed with a corresponding top thread structure, when the top thread is rotated, the top thread can be pushed to prop against the nut of the water pump, and then the locking nut is screwed, so that the locking nut props against the outer ring surface of the circular ring, thereby preventing the top thread from loosening when in use.
Examples
The rotary sleeve 6 is arranged at the hand-held position of the Z-shaped thin steel pipe. The rotary handle sleeve adopts a hollow steel pipe structure, and the steel pipe structure is inserted on the rod surface of the Z-shaped thin steel pipe, wherein a rolling bearing is connected between the Z-shaped thin steel pipe and the Z-shaped thin steel pipe, so that the rotary handle sleeve can be rotated on the Z-shaped thin steel pipe.
After the tightening force of the water feeding pump end cover nut is released under the operation of a heavy hydraulic wrench or the nut is screwed into the stud at the initial stage of the refitting, maintenance personnel can be assisted to rapidly rotate, disassemble and assemble the nut, when the water feeding pump end cover nut is used, the ring is sleeved on the water feeding pump end cover nut, then three jackscrews on the ring are respectively pushed in, the end parts of the three jackscrews are propped against the plane of the water feeding pump end cover nut, and then the locking nut on each jackscrew is respectively screwed, so that the jackscrews are prevented from loosening when the water feeding pump end cover nut is screwed. Then the rotary sleeve on the Z-shaped thin steel pipe is held, and the ring is driven to rotate by the Z-shaped thin steel pipe, so that the nut of the end cover of the water supply pump is disassembled.
