Description

Technical Field

[0001] This utility model relates to the field of pipe maintenance technology, and in particular to an auxiliary tool for opening up pipes. Background Technology

[0002] A pipe bank typically refers to a piping system used for a specific function. In thermal power generation, the heat energy generated by boiler combustion is transferred through the pipe bank. The pipe bank is part of the cooling system; cooling water flows through its pipes. When the high-temperature flue gas from boiler combustion passes through the pipe bank, it exchanges heat with the cooling water, transferring heat to the water within the pipes. This lowers the internal temperature of the boiler, preventing overheating and damage to the equipment. The cooling water, having absorbed the heat, turns into steam, driving the turbine to generate electricity.

[0003] Currently, the existing method for maintaining pipe banks is to manually secure the surrounding pipe banks of one pipe bank for maintenance. However, manual securing is time-consuming and labor-intensive, and the manual securing is not secure enough, which may result in accidental contact with other pipe banks, affecting the progress of subsequent pipe bank maintenance and reducing maintenance efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary tool for spreading out pipe arrays, so as to solve the problems existing in the prior art.

[0005] This utility model is implemented by the following technical solution: an auxiliary tool for spreading out a pipe array, comprising a vertical pipe with a closed bottom end, and a mounting base fixed at the top of the vertical pipe; a transmission shaft is provided vertically inside the vertical pipe, the bottom end of the transmission shaft is rotatably connected to the inner wall of the bottom end of the vertical pipe, and the top end of the transmission shaft passes through the bottom wall of the mounting base and is placed inside the mounting base. A first bevel helical gear is sleeved and fixed on the drive shaft inside the vertical tube. An active bevel helical gear that meshes with the first bevel helical gear is provided inside the vertical tube. A drive handle is provided outside the vertical tube. The connecting rod of the drive handle passes through the side wall of the vertical tube and the active bevel helical gear is sleeved and fixed on its end. A second bevel gear is fixedly mounted on the drive shaft inside the mounting base. Limiting openings are respectively opened on the opposite side walls of the mounting base. Two telescopic components are symmetrically arranged in the two limiting openings. Each telescopic component includes a fixed plate fixed inside the mounting base, a passive bevel gear that meshes with the second bevel gear inside the mounting base, a square horizontal tube that passes through the limiting opening and slides in contact with the limiting opening, and a threaded rod between the passive bevel gear and the square horizontal tube. The passive bevel gear is fixedly mounted on one end of the threaded rod, and the other end of the threaded rod rotates through the fixed plate and extends into the square horizontal tube and is threadedly connected to the inner wall of the square horizontal tube.

[0006] Preferably, a support plate is fixed to each end of the two square horizontal tubes outside the mounting base.

[0007] Preferably, several anti-slip blocks are fixed on the upper and lower sides of the square horizontal tube.

[0008] Advantages of this invention: This invention controls the rotation of the active bevel helical gear by rotating the drive handle. The rotation of the active bevel helical gear drives the rotation of the first bevel helical gear, which in turn drives the rotation of the transmission shaft. The rotation of the transmission shaft drives the rotation of the second bevel helical gear, which in turn drives the rotation of two passive bevel helical gears. When the two passive bevel helical gears rotate, they drive the corresponding threaded rods to rotate. Because the square horizontal tubes are restricted by the limiting openings that match their shape and size, both square horizontal tubes move along the length direction of the corresponding threaded rods, adjusting the distance between the two spreading plates to spread out the two adjacent pipe rows. This allows for adjustment of the distance between the two pipe rows. It replaces manual fixing and avoids accidental contact with other pipe rows due to insecure fixing, ensuring the progress of subsequent pipe row maintenance and improving maintenance efficiency.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] like Figures 1-3As shown, an auxiliary tool for spreading out a pipe array includes a vertical pipe 1 with its bottom closed, and a mounting base 2 fixed to the top of the vertical pipe 1; a drive shaft 3 is provided vertically inside the vertical pipe 1, the bottom end of the drive shaft 3 is rotatably connected to the inner wall of the bottom end of the vertical pipe 1, and the top end of the drive shaft 3 rotatably passes through the bottom wall of the mounting base 2 and is placed inside the mounting base 2. A first bevel gear 4 is fixedly mounted on the drive shaft 3 inside the vertical tube 1. An active bevel gear 5 that meshes with the first bevel gear 4 is provided inside the vertical tube 1. A drive handle 6 is provided outside the vertical tube 1. The connecting rod of the drive handle 6 passes through the side wall of the vertical tube 1 and the active bevel gear 5 is fixedly mounted on its end. By rotating the drive handle 6, the active bevel gear 5 is controlled to rotate. The rotation of the active bevel gear 5 drives the first bevel gear 4 to rotate. The first bevel gear 4 drives the drive shaft 3 to rotate. A second bevel gear 7 is fixedly mounted on a drive shaft 3 within the mounting base 2. Rotation of the drive shaft 3 drives the second bevel gear 7 to rotate. Limiting openings 2.1 are respectively opened on opposite side walls of the mounting base 2. These limiting openings 2.1 restrict the rotation of the square horizontal tube 8.3 of the telescopic assembly 8. Two symmetrical telescopic assemblies 8 are inserted into the two limiting openings 2.1. Each telescopic assembly 8 includes a fixed plate 8.1 fixed within the mounting base 2, a passive bevel gear 8.2 meshing with the second bevel gear 7 within the mounting base 2, a square horizontal tube 8.3 slidingly contacting the limiting opening 2.1, and a threaded rod 8.4 positioned between the passive bevel gear 8.2 and the square horizontal tube 8.3. The passive bevel gear 8.2 is fixedly mounted on one end of the threaded rod 8.4, and the other end of the threaded rod 8.4 rotates through the fixed plate 8.1 and extends into the square horizontal tube 8.3, where it meshes with the square horizontal tube 8.3. The inner wall of the horizontal tube 8.3 is threaded; two square horizontal tubes 8.3 outside the mounting base 2 are respectively fixed with a spreading plate 9 at their ends; the second bevel gear 7 rotates to drive two passive bevel gears 8.2 to rotate. When the two passive bevel gears 8.2 rotate, they drive the corresponding threaded rods 8.4 to rotate. Since the square horizontal tube 8.3 is restricted by the limiting port 2.1 that matches its shape and size, the two square horizontal tubes 8.3 move along the length direction of the corresponding threaded rods 8.4 to adjust the distance between the two spreading plates 9, so as to spread the two adjacent tube rows and adjust the distance between the two tube rows; several anti-slip blocks 10 are fixed on the upper and lower sides of the square horizontal tube 8.3. The anti-slip blocks 10 are used to prevent the spreading plate 9 from being subjected to excessive force and being penetrated by the square horizontal tube 8.3, causing relative displacement and causing the two tube rows to suddenly approach each other, thereby avoiding injury to the workers and further improving safety and reliability.

[0015] Instructions for use: When in use, the telescopic component 8 is in the retracted state; the operator inserts this tool between two adjacent pipe rows, and then rotates the drive handle 6 to control the active bevel gear 5 to rotate. The rotation of the active bevel gear 5 drives the first bevel gear 4 to rotate. The first bevel gear 4 drives the transmission shaft 3 and the second bevel gear 7 to rotate simultaneously. The rotation of the second bevel gear 7 drives the two passive bevel gears 8.2 to rotate. When the two passive bevel gears 8.2 rotate, they drive the corresponding threaded rods 8.4 to rotate. Since the square horizontal tubes 8.3 are restricted by the limiting port 2.1 that matches their shape and size, both square horizontal tubes 8.3 move along the length direction of the corresponding threaded rods 8.4 to adjust the distance between the two spreading plates 9, thereby spreading the two adjacent pipe rows and allowing adjustment of the distance between the two adjacent pipe rows.
