Description

Technical Field

[0001] The invention relates to the technical field of shock absorber disassembly and assembly devices, and in particular to a conical support shock absorber replacement tool and a replacement method. Background Art

[0002] Water pump mechanical equipment is widely used in urban water supply, sewage treatment, agricultural water conservancy projects, and the petroleum industry. Due to the working characteristics of the water pump, the water pump will generate severe vibration and noise under the conditions of start-stop, high-low speed conversion, and phase change of the working fluid. This vibration and noise will not only be transmitted to the ground and the surrounding environment through the supporting structure, causing a wide range of noise pollution; it is more likely to be transmitted to other key equipment through the pipeline, causing cracking of the pump casing, accelerated bearing wear, seal leakage, and invisible tiny cracks in the oil pipeline. Growth, shortening the service life of the water pump, pipelines and other equipment, and ultimately leading to major safety accidents and environmental accidents such as leakage of the transported working fluid. Therefore, a conical shock absorber (hereinafter referred to as the shock absorber) is provided at the bottom of the water pump support structure to reduce the impact of the water pump vibration on its own structure or other equipment. The working environment of the water pump support shock absorber is relatively harsh and harsh. The core structure of the shock absorber is made of rubber material. Under repeated alternating stress, the material will age and affect the shock absorption performance of the shock absorber. Therefore, the replacement of the shock absorber is involved in the daily use of the water pump.

[0003] There are 4 water pump support shock absorbers, located below the water pump and above the base. To replace the shock absorbers according to the traditional method in the order of equipment installation, the water pump needs to be shut down, and then the circuit system needs to be drained, the connecting pipes of the water pump need to be separated, the water pump needs to be lifted by a crane, and finally the shock absorber needs to be replaced. After the water pump support shock absorber is replaced, in addition to the reverse reinstallation operation of the above steps, tedious operation steps such as water replenishment and pressure testing of the circuit system are also required. The traditional method involves a large number of professional construction personnel, including circuit operators, crane personnel, professional water pump installers, mechanical installers, etc. The construction time is long, and many special tools and equipment are required for construction, and the construction personnel have high qualifications.

[0035] Example 1

[0036] like Figure 1-4 As shown, the present embodiment provides a conical support shock absorber replacement tooling, comprising a first pressure plate 1, a second pressure plate 2, a clamping block 3 and a thrust device 4, wherein the first pressure plate 1 and the second pressure plate 2 are detachably connected via the clamping block 3, and the first pressure plate 1 and the second pressure plate 2 are both provided with axial compression members for axially compressing the shock absorber; the thrust device 4 is detachably mounted on the first pressure plate 1 and the second pressure plate 2, and the thrust device 4 is provided with radial tightening members for radially adjusting the shock absorber.

[0037] The first pressure plate 1 and the second pressure plate 2 are connected by the clamping block 3 to ensure that the two pressure plates are located in the same horizontal plane and are not separated. The first pressure plate 1 and the second pressure plate 2 are connected to the upper half of the shock absorber by the axial compression member, respectively, so that the two pressure plates can withstand the axial stress used to compress the shock absorber and the radial stress that pushes the upper half of the shock absorber to move horizontally. The axial compression distance of the shock absorber is controlled by the axial compression member to reduce the axial height of the shock absorber and separate the shock absorber from the water pump. The thrust device 4 is installed on the first pressure plate 1 and the second pressure plate 2, and the radial pressing member on the thrust device 4 is abutted against the surface of the shock absorber. The radial pressing member is used to apply thrust to the upper half of the shock absorber.

[0038] In this embodiment, the first pressure plate 1 and the second pressure plate 2 are provided with a screw hole I9, a screw hole II10 and a screw hole III11. The screw hole I9 is ​​connected to the clamping block 3 through a bolt I7, the screw hole II10 is connected to the thrust device 4 through a bolt II8, and the axial compression member is arranged in the screw hole III11.

[0039] Among them, one side of the first pressure plate 1 and the second pressure plate 2 are both provided with an arc-shaped opening, which are connected to form a rectangular parallelepiped with a through hole in the middle. The diameter of the through hole is adapted to the outer diameter of the shock absorber, so that the first pressure plate 1 and the second pressure plate 2 can be sleeved on the surface of the shock absorber. The screw hole I10 is located at the end where the first pressure plate 1 and the second pressure plate 2 are connected to each other, the screw hole II10 can be located at the end where the first pressure plate 1 and the second pressure plate 2 are away from each other, the screw hole II10 can also be on the same side as the screw hole I9, and the screw hole III11 is close to the arc-shaped opening. The bolts connecting the thrust device 4 and the pressure plate should be able to withstand sufficient shear force and will not deform, crack, break, etc.

[0040] In this embodiment, the clamping block 3 is provided with a screw hole IV12 corresponding to the screw hole I9, and the bolt I7 is passed through the screw hole I9 and the screw hole IV12. The clamping block 3 is provided with two screw holes IV12, one of which is connected to the screw hole I9 on the first pressure plate 1 through a bolt I7, and the other is connected to the screw hole I9 on the second pressure plate 2 through another bolt I7, so as to realize the connection between the first pressure plate 1 and the second pressure plate 2.

[0041] In this embodiment, the axial compression member is a clamping bolt 5, the first end of the clamping bolt 5 is connected to the shock absorber, and the second end of the clamping bolt 5 is connected to the first pressure plate 1 or the second pressure plate 2 through the screw hole III11. The clamping bolt 5 is connected to the upper half of the shock absorber, so that when the clamping bolt 5 is tightened, the relative distance between the pressure plate and the upper half of the shock absorber can be compressed (that is, the elastic body of the shock absorber is compressed), so that the axial height of the shock absorber is reduced, and the shock absorber is separated from the water pump.

[0042] In this embodiment, the thrust device 4 includes a support section 41, a connection section 42 and a tightening section 43, the support section 41 and the tightening section 43 are respectively connected to the connection section 42 vertically, and the support section 41 and the tightening section 43 are on different sides, the connection section 42 is provided with a screw hole V13, the tightening section 43 is provided with a screw hole VI14, the bolt II8 is passed through the screw hole V13, and the radial tightening member is arranged in the screw hole VI14. When in use, the support section 41 is closely attached to the side wall of the first pressure plate 1 or the second pressure plate 2, and the connection section 42 is closely attached to the top of the first pressure plate 1 or the second pressure plate 2.

[0043] In this embodiment, the radial tightening member is a tightening bolt 6, which is inserted into the screw hole VI14, and the end of the tightening bolt 6 abuts against the shock absorber. The tightening bolt 6 is screwed into the screw hole VI14, and the thrust of the tightening bolt 6 on the shock absorber is adjusted by controlling the screwing length of the tightening bolt 6, so as to control the displacement and rotation of the upper half of the shock absorber on the horizontal plane, and remove the connecting bolts between the upper half of the shock absorber and the water pump support.

[0044] In this embodiment, there are at least two clamping blocks 3 and at least four thrust devices 4. The two clamping blocks 2 are used to connect the two ends of the first pressure plate 1 and the second pressure plate 2 respectively, so as to improve the stability after the connection. The four thrust devices 4 can be evenly distributed around the shock absorber, which makes it easier to adjust the radial position of the shock absorber. Alternatively, the four thrust devices are evenly distributed on opposite sides of the shock absorber.

[0048] S3. Use the clamping bolt 5 to connect the screw hole III11 on the first pressure plate 1 and the second pressure plate 2 to the shock absorber, and compress the upper elastic device of the shock absorber by tightening the clamping bolt 5; before compression, a temporary fixed support is required to replace the conical shock absorber to bear the total weight of the water pump and related connections;

[0050] S5. After the shock absorber is adjusted to a suitable position through step S4, the connecting bolts between the shock absorber and the water pump are loosened, the connecting bolts between the shock absorber and the lower base are removed, and the shock absorber is taken out to complete the disassembly and assembly of the shock absorber.

[0051] When reinstalling the shock absorber, install the replacement tool on the shock absorber, tighten the clamping bolt 5 to compress the relative distance between the first pressure plate 1, the second pressure plate 2 and the upper half of the shock absorber, and reduce the axial height of the shock absorber. Reinstall the shock absorber to the pressure-bearing position, and tighten the connecting bolts between the shock absorber and the lower base.
