Description

Technical Field

[0001] This utility model belongs to the technical field of power equipment maintenance, and specifically relates to an electric pressure spraying device for bolt disassembly. Background Technology

[0002] In power systems, the maintenance of substation equipment is crucial. When hot-point bolts in the equipment show signs of corrosion, workers face a series of challenges during bolt removal and installation. Corrosion not only complicates the process but can also affect the normal operation of the equipment. To effectively address this problem, workers typically need to first spray a loosening agent onto the hot-point bolts to remove rust, thus ensuring smooth disassembly and installation.

[0003] However, currently, the application of loosening agents mainly relies on manual operation by workers. Considering that power equipment is usually installed at high locations and that the operating space for some bolts is limited, this not only poses safety hazards for working at heights but also makes it difficult to maintain a stable spraying operation for extended periods, thus affecting the rust-removing effect of the loosening agent. Furthermore, because loosening agents have a certain degree of volatility or corrosiveness, direct manual operation may also pose a potential threat to the health of workers. Summary of the Invention

[0004] This utility model aims to provide an electric pressure spraying device, specifically designed for bolt disassembly operations in power equipment. Its design highlight lies in the integration of an electric pressing function, which enables automated spraying of the loosening agent, greatly reducing the labor intensity of workers and improving work efficiency.

[0005] To achieve the above objectives, this utility model provides an electric pressure spraying device for bolt disassembly. Its key features include: a placement cylinder for accommodating a loosening agent canister; a limit bolt detachably installed at the top of the placement cylinder corresponding to the loosening agent self-spraying valve; a through hole for the loosening agent spray pipe to pass through in the cylinder body; and a pressing drive at the bottom of the placement cylinder for lifting the loosening agent canister, causing the loosening agent self-spraying valve to squeeze the limit bolt, thereby achieving automatic spraying of the loosening agent through the loosening agent spray pipe.

[0006] Furthermore, the diameter of the cavity of the placement tube matches the diameter of the loosening agent container.

[0007] Furthermore, the limiting bolt is in the form of a bolt, with a handwheel connected to one end; a socket for bolt insertion is radially provided on the top of the placement cylinder.

[0008] Furthermore, the pressing drive includes an axially arranged electric push rod, the output end of which acts on the bottom of the loosening agent can.

[0009] Furthermore, a remote control module is connected to the control circuit of the electric linear actuator, which allows users to remotely control the electric linear actuator via a remote control.

[0010] Furthermore, the electric push rod is integrated into a mounting cylinder, the top of which expands radially to form an interface that nests with the placement cylinder, and the interface is fixed to the mounting cylinder with a wing screw.

[0011] Furthermore, the remote control module is externally mounted on the body of the mounting cylinder and connected to the control circuit of the electric push rod via a connecting wire.

[0012] Furthermore, a storage battery for power supply is also provided in the cavity of the mounting cylinder.

[0013] Furthermore, a connector for connecting the support rod is provided at the bottom of the mounting cylinder.

[0014] Compared with the prior art, the significant advantages of this utility model are:

[0015] By integrating an electric actuator as the pressing drive, stable and continuous pressure is applied to the loosening agent canister, thereby improving the uniformity and efficiency of loosening agent spraying. Simultaneously, the remote control module allows users to operate the electric actuator from a safe distance, avoiding direct contact with bolts and loosening agent in high-temperature or high-pressure environments, significantly improving operational safety.

Detailed Implementation

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0026] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] Figures 1 to 7The first embodiment of the present invention is shown: an electric pressure spraying device for bolt removal, comprising a placement cylinder 2 for accommodating a loosening agent canister 1, a limit bolt 4 detachably installed at the top of the placement cylinder 2 corresponding to a loosening agent self-spraying valve 3, a through hole 6 for a loosening agent spray pipe 5 to pass through in the cylinder body of the placement cylinder 2, and a pressing drive 7 provided at the bottom of the placement cylinder 2, the pressing drive 7 being used to lift the loosening agent canister 1, causing the loosening agent self-spraying valve 3 to squeeze the limit bolt 4, so as to realize the automatic spraying of loosening agent through the loosening agent spray pipe 5.

[0028] like Figure 3 As shown, specifically, the diameter of the cavity of the placement cylinder 2 matches the diameter of the loosening agent canister 1. Furthermore, to ensure that the limiting bolt 4 can stably fix the loosening agent self-spraying valve 3 and prevent it from slipping or shifting during pressing, the limiting bolt 4 is in the form of a bolt, with a handwheel 8 connected to one end. A bolt insertion hole 9 is radially provided at the top of the placement cylinder 2 for bolt insertion. This design not only facilitates the installation and removal of the limiting bolt 4 but also ensures a stable connection between the limiting bolt 4 and the placement cylinder 2 (see reference). Figure 4 and Figure 6 ).

[0029] from Figure 6 and Figure 7 As can be seen, in practical implementation, the pressing drive 7 is the core component of the device. It adopts an axially arranged electric push rod 701, the output end of which directly acts on the bottom of the loosening agent tank 1. When the electric push rod 701 is activated, it pushes the loosening agent tank 1 upward, thereby causing the loosening agent self-spraying valve 3 to squeeze the limit plug 4, and the loosening agent is automatically sprayed out through the spray pipe 5.

[0030] In this embodiment, the electric actuator 701 is selected with consideration for sufficient thrust and stable operating characteristics to ensure that sufficient pressure is generated when pressing the loosening agent canister 1, so that the loosening agent is sprayed out evenly and forcefully. A common electric actuator 701 model in the prior art can be used, and its thrust range can be adjusted according to actual usage requirements to meet the pressing needs of different loosening agent canisters 1, thereby ensuring that the loosening agent self-spraying valve 3 can be fully squeezed during the pressing process, achieving maximum spraying of the loosening agent.

[0031] Please see Figure 4 , Figure 5 and Figure 7To further enhance the convenience and practicality of the device, this embodiment also integrates a remote control module 702 into the control circuit of the electric push rod 701. This module allows users to remotely control the electric push rod 701 via a remote control, enabling pressing operations without close contact with the device. This design not only improves operational safety but also allows users to spray bolts from different angles and positions, greatly enhancing the flexibility and adaptability of the device. When the pressing drive 7 is activated, the electric push rod 701 starts, and its output end pushes the loosening agent canister 1 upward until the loosening agent self-spraying valve 3 is squeezed by the limit bolt 4. At this time, the loosening agent in the loosening agent canister 1 is sprayed out through the loosening agent spray nozzle 5 under pressure. Throughout the process, the operator only needs to operate the remote control module 702 via a remote control to start and stop the electric push rod 701, thereby completing the loosening agent spraying operation.

[0032] like Figures 4 to 7 As shown, in this embodiment, the electric actuator 701 is integrated into a mounting cylinder 703, and the mounting cylinder 704 is nested with the placement cylinder 2. The top of the mounting cylinder 703 expands radially to form an interface 704 that nests with the placement cylinder 2. The interface 704 and the mounting cylinder 703 are fixed together using wing screws 705. This design not only simplifies the assembly process of the device but also enhances its stability and durability. Furthermore, the wing screws 705 allow users to easily disassemble and replace device components, facilitating maintenance and upkeep.

[0033] Specifically, the remote control module 702 is externally mounted on the body of the mounting cylinder 703 and connected to the control circuit of the electric actuator 701 via a connecting wire. This external design not only facilitates the user's operation and observation of the remote control module but also effectively avoids heat dissipation and maintenance problems caused by an internal module. Furthermore, the connecting wire between the remote control module 702 and the electric actuator 701 is made of a highly elastic, wear-resistant material, ensuring stable signal transmission and a long service life.

[0034] Furthermore, considering that the electric pressure spraying device may need to operate for extended periods during use, this embodiment also includes a battery 706 installed in the cavity of the mounting cylinder 703 as a power source (see reference). Figure 4 and Figure 5The introduction of the storage battery 706 provides a stable power supply for the remote control module 702 and the electric actuator 701, ensuring the continuous and stable operation of the device. Simultaneously, the rechargeable design of the storage battery 706 allows users to charge the device whenever needed, extending its usage time. The preferred charging method for the storage battery 706 is a commonly available charging port, such as a Type-C or USB interface 704, allowing users to charge it with a standard charger. In some embodiments, the charging port of the storage battery 706 can be integrated into the body of the mounting sleeve 703. In other embodiments, the storage battery 706 can also be removable, allowing users to easily remove it for charging or replacement. This design not only improves the portability and flexibility of the device but also ensures its continuous operation in various working environments. To ensure the safe use of the storage battery 706, this embodiment also includes overcharge and over-discharge protection devices to prevent damage to the battery due to excessively high or low battery levels, thereby extending the service life of the storage battery 706.

[0035] from Figure 4 and Figure 6 As can be seen, a connector 707 for connecting the support rod is also provided at the bottom of the mounting cylinder 703. This design allows the device to be fixed in a suitable position by the support rod, which can ensure the stability of the device and the safety of the workers, especially when performing high-altitude operations.

[0036] In summary, this invention, by integrating an electric push rod 701 as a pressing drive 7, achieves stable and continuous pressure application to the loosening agent canister 1, thereby improving the uniformity and efficiency of loosening agent spraying. Simultaneously, the design of the remote control module 702 allows users to operate the electric push rod 701 from a safe distance, avoiding direct contact with bolts and loosening agent under high temperature or high pressure environments, significantly improving operational safety. Furthermore, the nested design of the mounting cylinder 703 and the placement cylinder 2, along with the fixing method of the wing screws 705, not only simplifies the assembly process but also enhances the stability and durability of the device. The introduction of the battery 706 provides convenient power support for the remote control module 702 and the electric push rod 701, while the design of the connector 707 facilitates flexible placement of the device in different working environments.

[0037] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
