Description

Technical Field

[0001] This utility model belongs to the technical field of impact turbines, and specifically relates to a novel piston hoisting tool for impact nozzle assembly. Background Technology

[0002] Currently, in nozzle assembly, the piston and nozzle shaft are vertically assembled. This allows either the nozzle shaft to be lifted and inserted into the piston, or vice versa. However, vertical assembly of the piston and nozzle shaft presents challenges due to the inverted piston shaft, making it difficult to use bolt pre-tightening devices. Furthermore, an excessively high piston shaft poses safety risks. Utility Model Content

[0003] In order to solve the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a new type of impact nozzle assembly piston hoisting tool, which can realize the horizontal assembly of piston and nozzle shaft, solve the problem of difficulty in using bolt pre-tightening device when piston shaft is installed upside down, and avoid the safety problems caused by excessive piston shaft height.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A novel piston lifting tool for assembling an impact nozzle includes a connecting plate that is connected to the end face of the piston when it is laid horizontally. A lifting plate and a support plate are respectively connected to the connecting plate. The support plate contacts the side of the piston. The lifting plate has screw holes for engaging the lifting eye bolts.

[0006] The connecting plate of this invention connects to the end face of the piston when it is laid horizontally. The screw holes on the lifting plate are used to install lifting eye bolts. After the piston is lifted, it can be horizontally mounted onto the nozzle shaft, achieving horizontal assembly. This invention avoids the difficulty of using bolt pre-tightening devices when assembling the piston shaft upside down, and also avoids safety issues caused by an excessively high piston shaft, by assembling the piston and nozzle shaft horizontally.

[0007] In a preferred embodiment of this invention, the line connecting the screw hole on the lifting plate to the piston's center of gravity is perpendicular to the piston's axis. By connecting the lifting eye bolts to the screw hole on the lifting plate, the piston is lifted. Since the line connecting the screw hole on the lifting plate to the piston's center of gravity is perpendicular to the piston's axis, the piston's axis remains horizontal. When the piston is horizontally mounted onto the nozzle shaft, the piston's axis and the nozzle shaft's axis are collinear, ensuring smooth installation.

[0008] In a preferred embodiment of this invention, a space is provided between the lifting plate and the side of the piston to allow for the eye bolt to pass. The lifting plate does not directly contact the piston, and sufficient height is provided to ensure the engagement of the eye bolt.

[0009] In a preferred embodiment of this utility model, the connecting plate includes a ring with two strip plates connected to it. One end of one strip plate is connected to a lifting plate, and the other end of the other strip plate is connected to a support plate. The ring is used to allow space for the super nut connected to the piston, and the two strip plates are used to connect to the end face of the piston, and can connect the lifting plate, support plate, and connecting plate into a whole.

[0010] In a preferred embodiment of this invention, the ring is coaxial with the piston, and the inner diameter of the ring is larger than the diameter of the super nut connected to the piston. The super nut can be inserted into the inner hole of the ring to avoid interference between them.

[0011] In a preferred embodiment of this utility model, the strip plate is connected to the piston.

[0012] In a preferred embodiment of this invention, the strip plate is provided with through holes, which are connected to the threaded holes on the piston by connecting screws. The strip plate has through holes with a circular size matching that of the piston's threaded holes, for engaging with the piston using connecting screws.

[0013] In a preferred embodiment of this invention, the two strip plates are collinear, and the straight line containing the strip plates passes through the center of the annulus. The lifting plate and the support plate are located at 180° to the piston circumference to ensure that the piston does not deflect during lifting and to ensure lifting stability.

[0014] In a preferred embodiment of this invention, the support plate is parallel to the piston axis. The support plate fits well against the side of the piston, ensuring reliable support and preventing excessive shear force on the connecting screws.

[0015] As a preferred embodiment of this utility model, the lifting plate is parallel to the axis of the piston.

[0016] The beneficial effects of this utility model are as follows:

[0017] The connecting plate of this invention connects to the end face of the piston when it is laid horizontally. The screw holes on the lifting plate are used to install lifting eye bolts. After the piston is lifted, it can be horizontally mounted onto the nozzle shaft, achieving horizontal assembly. This invention avoids the difficulty of using bolt pre-tightening devices when assembling the piston shaft upside down, and also avoids safety issues caused by an excessively high piston shaft, by assembling the piston and nozzle shaft horizontally.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other.

[0027] like Figures 1-6 As shown, the novel impact nozzle assembly piston lifting tool of this embodiment includes a connecting plate 1, which is connected to the end face of the piston 5 when it is laid flat. A lifting plate 2 and a support plate 3 are respectively connected to the connecting plate 1. The support plate 3 is in contact with the side of the piston 5. A screw hole 21 for engaging the lifting ring screw is opened on the lifting plate 2.

[0028] The connecting plate 1 of this invention connects to the end face of the piston 5 when it is laid horizontally. The screw holes 21 on the lifting plate 2 are used to install lifting eye bolts. After the piston 5 is lifted, it can be horizontally mounted onto the nozzle shaft, achieving horizontal assembly. This invention avoids the difficulty of using a bolt pre-tightening device when assembling the piston 5 shaft upside down, and also avoids safety issues caused by the piston 5 shaft being too high, by assembling the piston 5 and nozzle shaft horizontally.

[0029] It should be noted that the line connecting the screw hole 21 on the lifting plate 2 and the center of gravity of the piston 5 is perpendicular to the axis of the piston 5. After connecting the eye bolt to the screw hole 21 on the lifting plate 2, the piston 5 is lifted. Since the line connecting the screw hole 21 on the lifting plate 2 and the center of gravity of the piston 5 is perpendicular to the axis of the piston 5, the axis of the piston 5 remains horizontal. When the piston 5 is installed laterally onto the nozzle shaft, the axis of the piston 5 is collinear with the axis of the nozzle shaft, ensuring smooth installation.

[0030] Furthermore, a space is provided between the lifting plate 2 and the side of the piston 5 to avoid the eye bolt. The lifting plate 2 does not directly contact the piston 5, and there is sufficient height to ensure the engagement of the eye bolt.

[0031] Specifically, the connecting plate 1 includes a ring 11, on which two strip plates 12 are connected. One end of one strip plate 12 is connected to the lifting plate 2, and the other end of the other strip plate 12 is connected to the support plate 3. The ring 11 is used to allow the super nut connected to the piston 5 to pass, and the two strip plates 12 are used to connect to the end face of the piston 5, and can connect the lifting plate 2, the support plate 3 and the connecting plate 1 into a whole.

[0032] The ring 11 is coaxial with the piston 5, and the inner diameter of the ring 11 is larger than the diameter of the super nut connected to the piston 5. The super nut can be inserted into the inner hole of the ring 11 to avoid interference between them.

[0033] Specifically, the strip plate 12 is connected to the piston 5. The strip plate 12 has through holes, which are connected to the screw holes 21 on the piston 5 via connecting screws 4. The strip plate 12 has through holes with a distribution circle size matching the screw holes 21 on the piston 5, for engaging with the piston 5 via connecting screws 4.

[0034] The two strip plates 12 are collinear, and the line containing the strip plates 12 passes through the center of the ring 11. The lifting plate 2 and the support plate 3 are located at 180° around the circumference of the piston 5 to ensure that the piston 5 does not deflect during lifting and to ensure lifting stability.

[0035] The support plate 3 is parallel to the axis of the piston 5. The support plate 3 fits well with the side of the piston 5, ensuring reliable support and preventing excessive shear force on the connecting screw 4.

[0036] The lifting plate 2 is parallel to the axis of the piston 5.

[0037] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
