Description

Technical Field

[0001] The utility model belongs to the technical field of installation tools, and more specifically, relates to an installation tool for a heat exchanger of a gas water heater. Background Art

[0002] When a gas water heater is in use, the gas will fully burn in the combustion chamber and release huge heat energy. The heat generated by the gas combustion is then transferred to the cold water through the heat exchanger, making cold water heating a key device for hot water. The heat exchanger of a gas water heater is usually large in size and heavy in weight. In order to ensure the stability of the heat exchanger during installation, heat exchanger installation tooling is often used.

[0024] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following embodiments are used to illustrate the technical solution of the present invention, but are not intended to limit the scope of protection of the present invention.

[0025] Example:

[0026] like Figures 1 to 6As shown, the present invention provides a gas water heater heat exchanger installation tool, including a main rod 11 and two sets of fixed frames 12. The two sets of fixed frames 12 are located at both ends of the main rod 11, laying a basic framework structure for the entire tool. A transmission screw 13 is provided on the fixed frame 12, and the two ends of the main rod 11 are respectively mounted on the transmission screw 13. When an external power source acts on the transmission screw 13, it can drive the main rod 11 to move in a specific direction on the screw. Below the main rod 11, an electric lifting rod 21 and a connecting frame 22 are arranged. The electric lifting rod 21 provides the possibility of adjusting the heat exchanger body 14 in the vertical direction. A moving component is also provided on the main rod 11. This moving component is connected to one end of the electric lifting rod 21, and the other end of the electric lifting rod 21 is connected to the connecting frame 22, so that the various components can work together. Two sets of bidirectional screws 23 are provided on the connecting frame 22. Two sets of clamping assemblies are sleeved between the two sets of bidirectional screws 23. The clamping assemblies are slidably connected to the bidirectional screws 23, and the spacing between the clamping assemblies can be adjusted as needed. The heat exchanger body 14 is precisely clamped between the two sets of clamping assemblies. When the bidirectional screws 23 rotate, the clamping assemblies slide on the screws according to the direction of rotation of the screws, thereby achieving the clamping operation of heat exchanger bodies 14 of different sizes. Through the close cooperation between the various components of the entire tooling, the heat exchanger body 14 can be positioned, adjusted, and clamped in multiple directions, thus providing reliable protection for the installation of gas water heater heat exchangers.

[0027] like Figure 2 、 Figure 4 As shown, the moving assembly includes two sets of slide rails 31. Mounting grooves 32 are provided on both sides of the main rod 11. The slide rails 31 can be clamped in the mounting grooves 32 to ensure the relative position relationship between the slide rails 31 and the main rod 11. Two sets of connecting columns 33 are provided at the bottom of the mounting grooves 32. Correspondingly, connecting holes are provided on the slide rails 31 for the connecting columns 33. The connecting columns 33 can pass through the connecting holes and are provided with connecting nuts. The slide rails 31 can not only be connected to the main rod 11, but also be slidably connected to the main rod 11. An electric slider 34 is slidably provided on the slide rails 31. The electric slider 34 can slide smoothly on the slide rails 31 and is driven by electricity to adjust the position.

[0028] The moving assembly also includes a moving frame 35, with two sets of electric sliders 34 positioned between them. A fixing bump 36 is positioned on one side of the electric slider 34, and fixing slots 37 are defined on both sides of the moving frame 35. The fixing bumps 36 are locked into the fixing slots 37, establishing a secure connection between the electric slider 34 and the moving frame 35. Furthermore, two sets of fixing plates 38 are positioned on either side of the moving frame 35, with the fixing bumps 36 locked between the two sets of fixing plates 38, further enhancing the stability of the connection. To ensure a secure connection, both the fixing bumps 36 and the fixing plates 38 have first fixing holes, into which fixing bolts 39 are inserted, preventing any loosening during operation.

[0029] The electric lift rod 21 is positioned below the mobile frame 35. A limit block 24 is positioned at the top of the electric lift rod 21, while the mobile frame 35 defines a limit slot 25 corresponding to the limit block 24. The limit block 24 engages within the limit slot 25, ensuring a more precise connection between the electric lift rod 21 and the mobile frame 35. Furthermore, both the electric lift rod 21 and the mobile frame 35 feature multiple sets of secondary fixing holes, through which fixing bolts are inserted. The tightening action of the fixing bolts further ensures the secure and stable connection between them, ensuring stable operation of the entire structure during operation.

[0030] like Figure 2 、 Figure 3 As shown, the clamping assembly includes a clamping plate 41, a key component that directly contacts and clamps the heat exchanger body 14. Two sets of movable holes 42 are defined in the clamping plate 41, through which the bidirectional screw 23 passes. This creates a sliding connection between the clamping plate 41 and the bidirectional screw 23. When the bidirectional screw 23 rotates, the clamping plate 41 slides on the screw in the direction of rotation, thereby enabling the clamping or loosening of heat exchanger bodies 14 of different sizes.

[0031] A limit plate 43 is provided on one side of the clamping plate 41, and both the limit plate 43 and the clamping plate 41 are in contact with the heat exchanger body 14. The presence of the limit plate 43 provides an additional limiting function for the heat exchanger body 14. It works in conjunction with the clamping plate 41 to determine the position of the heat exchanger body 14, prevent unnecessary displacement of the heat exchanger body 14 during the clamping process, and ensure its stability during installation. Two sets of reinforcement rods 44 are provided on the other side of the clamping plate 41, and a sleeve 45 is provided at one end of the reinforcement rod 44. The sleeve 45 is sleeved on the bidirectional screw 23. The combination of the reinforcement rod 44 and the sleeve 45 provides more stable support for the sliding of the clamping plate 41 on the bidirectional screw 23, enhances the stability of the clamping plate 41 during operation, and ensures that it can withstand the corresponding pressure when clamping the heat exchanger body 14 without deformation or shaking.

[0032] The clamping assembly also includes an energizing seat 46 and a pressure sensor 47. The clamping plate 41 is provided with a first slot 48 and a second slot 49. The energizing seat 46 is positioned within the first slot 48, and an electromagnet is housed within the energizing seat 46. When energized, the electromagnet generates a strong suction force, which further enhances the securing effect on the heat exchanger body 14, making the heat exchanger body 14 more stable during installation. The pressure sensor 47 is positioned within the second slot 49 and in contact with the heat exchanger body 14. The pressure sensor 47 can detect the clamping pressure in real time. When the clamping plate 41 contacts the heat exchanger body 14, the pressure sensor 47 also contacts the heat exchanger body 14, and the first motor 27 stops rotating. This ensures that the clamping force remains within the appropriate range, ensuring that the heat exchanger body 14 is securely clamped while preventing damage to the heat exchanger body 14 due to excessive clamping force.

[0033] like Figure 2 、 Figure 5 As shown, the bidirectional screw 23 plays a key role in transmission and regulation in the operation of the entire gas water heater heat exchanger installation tool. A transmission wheel 26 is located at one end of the bidirectional screw 23. There are two sets of transmission wheels 26, connected by a transmission belt. When one of the transmission wheels 26 receives power, the power is evenly transferred to the other transmission wheel 26 via the transmission belt, ensuring that the two sets of bidirectional screws 23 operate synchronously and in a coordinated manner.

[0034] A first motor 27 is mounted at one end of the connecting frame 22. The shaft end of the first motor 27 is connected to one of the two sets of bidirectional screws 23. When the first motor 27 is powered, its shaft begins to rotate, directly driving the two bidirectional screws 23 connected to it. Because the two sets of bidirectional screws 23 are connected to the transmission belt via a transmission pulley 26, the other set of bidirectional screws 23 also rotates synchronously. This ensures that the sliding operation of the clamping assembly on the bidirectional screws 23 is synchronized, effectively clamping or loosening heat exchanger bodies 14 of different sizes.

[0035] A second motor 28 is mounted at one end of the mounting bracket 12, and the shaft end of the second motor 28 is connected to the transmission screw 13. When the second motor 28 starts operating, the rotation of the motor shaft end drives the transmission screw 13, thereby enabling the main rod 11 to move left and right along the transmission screw 13, facilitating the removal and installation of the heat exchanger body 14 and allowing the heat exchanger body 14 to be flexibly adjusted according to actual needs.

[0036] A control panel 29 is installed on one of the mounting brackets 12. The operator can use this control panel 29 to control the first motor 27 and the second motor 28, such as starting, stopping, and adjusting the motor speed, thereby controlling the movement of each component of the fixture. The control panel 29 can be equipped with the Mitsubishi FX3U series FX3U-32MT / ES-A controller. Multiple mounting holes 15 are also provided at both ends of the mounting bracket 12. These mounting holes 15 provide multiple options for installing and securing the fixture. Whether the fixture is mounted on a specific workbench or integrated with other equipment, these mounting holes 15 ensure a secure connection, ensuring the stability and reliability of the fixture during operation.

[0037] The basic principles, main features and advantages of the present invention are shown and described above. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
