Description

Technical Field

[0001] This utility model relates to the technical field of tower fan testing, and in particular to a tower fan load-bearing testing workbench. Background Technology

[0002] Tower fans, as a common household appliance, may be subjected to various external forces during use, among which load-bearing capacity is crucial to their stability and safety. Currently, the market lacks a reasonable and efficient load-bearing testing solution specifically for tower fans, making it impossible to accurately simulate the load-bearing scenarios that may be encountered in actual use. This makes it difficult to accurately assess the performance and structural reliability of tower fans under different load-bearing conditions, resulting in some tower fans with potential load-bearing safety hazards entering the market and posing potential risks to consumers. Utility Model Content

[0003] The present invention aims to overcome the shortcomings of existing technologies in accurately testing the load-bearing capacity of tower fans, and provides a tower fan load-bearing test bench that can simulate various load-bearing conditions in actual use of tower fans.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A tower fan load-bearing test bench includes:

[0006] A support frame, the upper end of which is equipped with a controller;

[0007] A lifting assembly is mounted on the upper end of a support frame, and one end of the lifting assembly is slidably connected to the support frame.

[0008] A displacement component, wherein the displacement component is mounted on the lifting component and is slidably connected to the lifting component;

[0009] A clamping assembly, which is mounted on and detachably connected to the displacement assembly;

[0010] A counterweight assembly, wherein the counterweight assembly is installed at the lower end of the support frame and corresponds to the clamping assembly;

[0011] The tower fan body has its upper end connected to a clamping assembly and its lower end connected to a counterweight assembly. A test sensor is installed on the tower fan body and is electrically connected to a controller.

[0012] Several components and a moving assembly are installed on a support frame. When the tower fan body needs to be tested, the upper end of the tower fan is clamped by a clamping assembly installed on the displacement assembly, suspending the tower fan body. Then, a counterweight assembly is connected to the lower end of the tower fan. A lifting assembly then pulls up the displacement assembly and clamping assembly, causing the tower fan body to move, so that the tower fan body fully bears the weight of the counterweight assembly. The load can be changed by the weight of the counterweight assembly. The tower fan body is then observed and its deformation, component displacement, and any abnormal noises are recorded. Then, the displacement assembly causes the tower fan body to deflect, applying a lateral force to the tower fan body. Different angle off-center load tests are performed on the tower fan body to simulate the external force tilting situation that may occur in actual use. During the test, the state of the tower fan body is accurately measured by test sensors, and the data is analyzed and processed by the controller to ensure the accuracy of the test. This achieves the purpose of simulating various load-bearing conditions of tower fans in actual use.

[0013] Preferably, the support frame includes a base plate, a protective frame, and a lifting frame. The protective frame is mounted on the base plate and corresponds to it. The lifting frame is mounted on one side of the base plate and has a U-shaped cross-section. The lifting frame includes side rods and a top rod. There are two side rods, each located at one end of the top rod. One end of each side rod is connected to the top rod, and the other end is connected to the base plate. One side of the protective frame is connected to the side rod. Several evenly distributed casters are mounted on the base plate. Four casters are installed at the four corners of the base plate. The support frame can be moved or locked using the casters. The protective frame on the base plate protects the front end of the base plate, while the lifting frame is installed at the rear end. A lifting assembly is installed on the lifting frame. The U-shape of the lifting frame facilitates the installation of external components. The connection between the protective frame and the lifting frame ensures the stability of the lifting frame. The protective frame protects the devices on the base plate during movement. This design ensures the stability of the support frame.

[0014] Preferably, the lifting assembly includes a motor and a lifting plate. A motor mount is installed on the top rod, and the motor is mounted on the motor mount. Sliding blocks are installed on both sides of the lifting plate, and sliding grooves are provided on each side rod. The lifting plate is slidably connected to the side rods through the cooperation of the sliding blocks and sliding grooves. A connecting block is installed on the lifting plate. A reel is installed on the motor shaft of the motor, and a winding rope is provided on the reel. One end of the winding rope is connected to the reel, and the other end of the winding rope is connected to the connecting block. The lifting plate of the lifting assembly is installed on the side rods of the lifting frame and is slidably connected to the side rods through the cooperation of the sliding blocks and sliding grooves. The lifting plate can move up and down along the sliding grooves. The motor is mounted on the motor mount on the top rod. The motor drives the reel to rotate, and the rotation of the reel can wind up and unwind the winding rope. Since the lower end of the winding rope is connected to the connecting block on the lifting plate, the connecting block acts on the lifting plate to drive the lifting plate to move up and down. This design can realize the lifting action.

[0015] Preferably, the displacement assembly includes a pneumatic cylinder and a moving plate. The lifting plate has a moving groove, one side of the moving plate is attached to one side of the lifting plate, and a moving rod is installed on one side of the moving plate. One end of the moving rod is connected to the moving plate, and the other end of the moving rod passes through the moving groove and is placed at the other end of the lifting plate. A limit plate is installed on the moving rod. The pneumatic cylinder is placed on the side of the moving rod where the limit plate is installed and is mounted on the lifting plate. The pneumatic end of the pneumatic cylinder is connected to the moving rod. The displacement assembly is mounted on the lifting plate, and the moving plate of the displacement assembly moves within the moving groove of the lifting plate via the moving rod. A clamping assembly is installed on the moving plate of the displacement assembly. The moving plate drives the clamping assembly to move. The limit plate installed on the moving rod can restrict the moving plate within the moving groove, ensuring the smooth movement of the moving plate. The movement of the moving rod can be pushed by the moving end of the pneumatic cylinder, which pushes the moving rod to move within the moving groove, thereby moving the moving plate. This design can achieve lateral offset.

[0016] Preferably, the clamping assembly includes an extension plate, a bonding plate, and a clamping plate. A mounting bracket is mounted on the movable plate, and the mounting bracket has a U-shaped cross-section. One end of the extension plate is detachably connected to the mounting bracket, and the other end of the extension plate is connected to the bonding plate. The extension plate has a bonding groove one, which corresponds to the tower fan body. A locking block is installed in the bonding groove one of the extension plate. The clamping plate is mounted on the upper end of the bonding plate and is detachably connected to the bonding plate. The clamping plate has a bonding groove two, which corresponds to the tower fan body. The bonding groove one and the bonding groove two are matched. The extension plate of the clamping assembly is installed on the mounting bracket of the movable plate and fixed with screws. The installation of the extension plate via the mounting bracket allows for quick installation without affecting the movement of the movable plate. After the extension plate is installed via the mounting bracket, a bonding plate is installed at the end of the extension plate. The bonding groove one on the bonding plate is bonded to the upper end of the tower fan body, and the upper end of the tower fan body is positioned and supported by a locking block. Then, a clamping plate is installed on the bonding plate with screws. The clamping plate is bonded to the tower fan body via a second bonding groove. During the installation of the clamping plate, the upper end of the tower fan body is restricted between the first and second bonding grooves, clamping and suspending the upper end of the tower fan body. This design can suspend the tower fan body.

[0017] Preferably, the counterweight assembly includes a placement plate and counterweight blocks. The placement plate is placed on a base plate, and a screw is mounted on the placement plate.

A fixing plate is provided on the screw, and a nut is provided on the fixing plate. The nut is threadedly connected to the screw. A hook is installed on the fixing plate, and the upper end of the hook is connected to the tower fan body. The counterweight assembly is installed on the base to apply pressure to the tower fan body. The counterweight blocks are stacked sequentially on the placement plate. The load is changed by changing the weight of the counterweight blocks. The counterweight blocks on the placement plate are constrained by the screw passing through the through hole. After constraining the counterweight blocks, a fixing plate is installed on the top layer to fix the counterweight blocks to the placement plate. The fixing plate is also screwed through and fits against the counterweight blocks. Then, the fixing plate and counterweight blocks are fixed to the placement plate by a nut. The hook installed on the fixing plate can be connected to the lower end of the tower fan body. This design can apply load to the tower fan body.

[0018] Preferably, the controller is installed at the upper end of the lifting frame. The test sensors include a displacement sensor and a stress sensor, both of which are mounted on the tower fan body and electrically connected to the controller. The controller, installed at the upper end of the lifting frame, controls the electronic components to automate the testing process. The stress sensor, mounted on the tower fan body, detects stress changes during the test and transmits the electrical signals to the controller for analysis. A displacement sensor, installed at the lower end of the tower fan body, detects the displacement distance of the tower fan body. The displacement data detected by the displacement sensor is transmitted to the controller for analysis. This design allows for more precise numerical measurements.

[0039] like Figure 6 As shown, the clamping assembly 4 includes an extension plate 41, a bonding plate 42, and a clamping plate 43. A mounting bracket 35 is installed on the movable plate 32. The cross-sectional shape of the mounting bracket 35 is U-shaped. One end of the extension plate 41 is detachably connected to the mounting bracket 35, and the other end of the extension plate 41 is connected to the bonding plate 42.
