Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and mainly to a general-purpose auxiliary test stand for testing the performance of air conditioning units. Background Technology

[0002] As a key component of an air conditioning system, the performance of the air conditioning unit directly affects the overall system's operation, energy efficiency, and indoor comfort. Comprehensive and accurate testing of the air conditioning unit is crucial to ensuring its quality and performance meet design requirements. Testing allows for the evaluation of various functions, including cooling, heating, ventilation, and air purification, identifying potential problems and providing a basis for product optimization and quality control. Therefore, an auxiliary lifting platform is needed to facilitate air conditioning unit performance testing. Currently, most air conditioning performance testing relies on traditional methods, such as manual handling or simple supports.

[0003] However, the applicant believes that the existing technology has significant shortcomings: 1. Insufficient versatility: Traditional methods are typically designed for air conditioning units of specific specifications and cannot adapt to air conditioning units of different sizes and weights. For large or specially shaped air conditioning units, traditional methods are difficult to meet testing requirements. 2. Limited functionality: Lacking auxiliary functions for adjusting height, angle, etc., it cannot meet the demand for multi-functional integration in modern air conditioning unit performance testing. 3. Poor mobility: Simple supports are usually fixed to the ground or test bench, making it difficult to move flexibly between different testing locations.

[0004] Therefore, there is an urgent need for an auxiliary platform that is versatile, fully functional, and easy to move. Utility Model Content

[0005] To address the above issues, a versatile, fully functional, easily movable, and highly stable auxiliary platform was developed. Through the design of its guardrail components, it became suitable for various models of air conditioning units. The position of the guardrail components can be adjusted according to the different sizes and models of the air conditioning units, effectively improving the applicability of the auxiliary platform.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A general-purpose auxiliary test stand for air conditioning unit performance, comprising:

[0008] Frame and adjustment mechanism;

[0009] The frame includes a base, a platform, and a guardrail assembly. The base is movable, and the platform is rotatably mounted on top of the base. The platform can be freely flipped to adjust its tilt angle and is used to support the air conditioning unit. The guardrail assembly is mounted on the platform and protects the air conditioning unit.

[0010] The adjustment mechanism is mounted on the base and includes a tilting component and a lifting component. The tilting component is mounted on the rotation axis of the platform and adjusts the tilt angle of the platform. The lifting component is located directly below the platform and adjusts the lifting height of the platform.

[0011] As an improvement, the guardrail assembly includes a side stop, a rear stop, an upper stop, and a front limit bar;

[0012] The side stops are symmetrically arranged on both sides of the platform along its length, and the side stops are vertically arranged.

[0013] The rear stop bar is installed on one side of the platform in the width direction, and the rear stop bar is vertically arranged;

[0014] The upper stop lever is adjusted for lifting and sliding between the side stop levers, and the upper stop lever is horizontally positioned.

[0015] The front limit rod is raised and lowered synchronously with the upper stop rod, and the front limit rod is flipped and swung relative to the upper stop rod.

[0016] As an improvement, the upper stop lever and the rear stop lever are guided to slide and rise together via a thin guide rod.

[0017] As an improvement, the upper stop bar is provided with an upward-opening U-shaped limiting groove, and the front limiting bar is provided with a limiting rod that corresponds to and cooperates with the U-shaped limiting groove. The limiting rod is engaged with the U-shaped limiting groove through a limiting nut provided at the suspended end.

[0018] As an improvement, the flipping assembly includes a flipping reducer and a flipping crank;

[0019] The tilting reducer is installed and connected to the lifting assembly. The tilting reducer uses a worm gear transmission structure to drive the rotating shaft to rotate.

[0020] The flip handle is installed on the outside of the flip reducer. The flip handle is connected to the worm gear of the flip reducer, and the flip handle drives the rotating shaft to rotate and adjust through the flip reducer.

[0021] As an improvement, the lifting assembly includes a lifting reducer, a lifting seat, a guide rod, and a lifting crank;

[0022] The lifting reducer is fixedly installed on the base. The lifting seat is installed on the top of the lead screw of the lifting reducer. The platform is rotatably installed on the lifting seat via a rotating shaft. The guide rods are symmetrically installed on both sides of the lifting reducer, supporting the two ends of the platform along its length. The lifting reducer drives the platform to lift and lower via a worm gear lead screw lifting structure. The lifting handle is installed on the outside of the lifting reducer and is connected to the worm gear in the lifting reducer. Rotating the lifting handle drives the worm gear to rotate.

[0023] As an improvement, the four corners of the platform and the base are all provided with linkage support mechanisms, which include swing arms, support rods and second limiting nuts;

[0024] The swing arm is rotatably hinged to the bottom of the platform;

[0025] The support rod is vertically mounted on the base. The top of the support rod is hinged to the swing arm, and the bottom of the support rod is inserted into the waist-shaped guide groove of the base through the limiting support of the second limiting nut.

[0026] The second limiting nut is threaded onto the support rod and abuts against the base.

[0027] As an improvement, the base is provided with omnidirectional casters at each of its four corners, and each omnidirectional caster is equipped with a braking unit.

[0028] The beneficial effects of this utility model are as follows:

[0029] (1) The guardrail assembly adjustment platform designed in this utility model can be flexibly flipped up and down by the front limit rod in the guardrail assembly. At the same time, the upper stop rod and the front limit rod can be vertically raised and lowered and horizontally moved according to the actual size of the air conditioner box. Whether it is a small household air conditioner or a large commercial air conditioner, as long as it is within the adjustment range of the platform, it can be tested. This makes the platform more widely applicable, can meet the testing needs of different users and different products, and improves the applicability of the auxiliary platform.

[0030] (2) The present invention also includes a flipping component and a lifting component. The angle of the platform can be adjusted by the flipping component and the height of the platform can be adjusted by the lifting component. The multifunctional platform with the flipping component and the lifting component can be integrated, eliminating the need to frequently change different platforms or equipment for different test requirements. When testing the performance of the air conditioning unit, it is necessary to test its performance when it is installed horizontally, as well as its performance when it is installed at a certain tilt angle and at different heights. This can meet the requirements of different test conditions, greatly save test time and cost, and improve test efficiency.

[0031] (3) The present invention also includes universal casters, which can move the platform to the most suitable position according to different testing needs and site conditions. Whether in different areas inside the laboratory or between different laboratories, or even in temporary outdoor testing sites, it can be quickly set up and tested without being restricted by a fixed position. When the platform is not in use, it can be moved to a place that does not occupy the main work space, providing space for other experimental equipment or work areas.

[0032] (4) The general-purpose auxiliary test stand for testing the performance of air conditioning units of this utility model also effectively improves safety. When manually moving large and heavy air conditioning units, there are certain safety risks, such as operators being injured by heavy objects or twisting their waists. The adjustable auxiliary stand separates the operators from the heavy handling work, reduces the possibility of accidents, and creates a safer working environment for the operators.

[0033] In summary, the universal auxiliary test stand for air conditioning unit performance testing of this utility model effectively improves testing efficiency, expands testing versatility, and enhances operational safety. Attached Figure Description

[0047] Example 1:

[0048] like Figures 1 to 9 As shown, a general-purpose auxiliary test stand for air conditioning unit performance includes:

[0049] Platform 1 and adjustment mechanism 2;

[0050] The platform 1 includes a base 11, a platform 12, and a guardrail assembly 13. The base 11 is movable, and the platform 12 is rotatably mounted on the top of the base 11. The platform 12 can be freely flipped to adjust its tilt angle, and the platform 12 is used to support the air conditioning unit. The guardrail assembly 13 is disposed on the platform 12 and protects the air conditioning unit.

[0051] The adjustment mechanism 2 is installed on the base 11. The adjustment mechanism 2 includes a flipping component 21 and a lifting component 22. The flipping component 21 is installed at the rotation axis 121 of the platform 12 and adjusts the tilt angle of the platform 12. The lifting component 22 is located directly below the platform 12 and adjusts the lifting height of the platform 12.

[0052] The guardrail assembly 13 includes a side stop 131, a rear stop 132, an upper stop 133, and a front limit rod 134;

[0053] The side stops 131 are symmetrically arranged on both sides of the platform 12 along its length, and the side stops 131 are vertically arranged.

[0054] The rear stop bar 132 is installed on one side of the platform 12 in the width direction, and the rear stop bar 132 is vertically arranged;

[0055] The upper stop lever 133 is adjusted and installed between the side stop levers 131, and the upper stop lever 133 is horizontally set.

[0056] The front limit rod 134 is raised and lowered synchronously with the upper stop rod 133, and the front limit rod 134 is flipped and swung relative to the upper stop rod 133.

[0057] The upper stop bar 133 and the rear stop bar 132 are slidably raised and lowered by a thin guide rod 135.

[0058] The upper stop bar 133 is provided with an upward-opening U-shaped limiting groove 136, and the front limiting bar 134 is provided with a limiting bar 137 that corresponds to and cooperates with the U-shaped limiting groove 136. The limiting bar 137 is engaged with the U-shaped limiting groove 136 through a limiting nut 138 provided at the suspended end.

[0059] It should be noted that both the side stop bar 131 and the rear stop bar 132 are provided with elongated sliding grooves 130. The thin guide rod 135 passes through the sliding groove 130 and is fixed by a nut. The two ends of the front limit bar 134 are also provided with movable grooves 1341. Screws pass through the movable grooves 1341 at both ends and connect to the two ends of the upper stop bar 133. When the guardrail assembly 13 is adjusted according to the air conditioning unit of different sizes, the upper stop bar 133 can be moved vertically through the sliding groove 130 to adjust the height. At the same time, the front limit bar 134 can be flipped and set at both ends of the upper stop bar 133 through the movable groove 1341. The front limit bar 134 can also be moved horizontally through the movable groove 1341 to adjust the width, so that the guardrail assembly 13 fully covers and resists the air conditioning unit to stabilize and limit it.

[0060] The flipping assembly 21 includes a flipping reducer 211 and a flipping crank 212;

[0061] The tilting reducer 211 is installed and connected to the lifting assembly 22. The tilting reducer 211 uses a worm gear transmission structure to drive the rotating shaft 121 to rotate.

[0062] The flip handle 212 is installed on the outside of the flip reducer 211. The flip handle 212 is connected to the worm gear of the flip reducer 211, and the flip handle 212 drives the rotating shaft 121 to rotate and adjust through the flip reducer 211.

[0063] It should be noted that the rotation reducer 211 on the rotation assembly 21 uses a WPX reducer. The WPX reducer uses a worm gear and worm wheel meshing transmission. The worm gear and worm wheel mesh with each other. When the worm gear rotates, it drives the worm wheel to rotate, thereby realizing the speed reduction function. The transmission ratio of the rotation reducer 211 is 60. When the worm gear lead angle is less than the friction angle, it can achieve self-locking and limit the pitch angle of the air conditioning unit.

[0064] The lifting assembly 22 includes a lifting reducer 221, a lifting seat 222, a guide rod 223, and a lifting crank 224;

[0065] The lifting reducer 221 is fixedly mounted on the base 11. The lifting seat 222 is installed on the top of the lead screw of the lifting reducer 221. The platform 12 is rotatably mounted on the lifting seat 222 via the rotating shaft 121. The guide rods 223 are symmetrically installed on both sides of the lifting reducer 221. The guide rods 223 support the two ends of the platform 12 in the length direction. The lifting reducer 221 drives the platform 12 to lift and lower through the worm gear lead screw lifting structure. The lifting handle 224 is installed on the outside of the lifting reducer 221. The lifting handle 224 is connected to the worm gear in the lifting reducer 221. The rotation of the lifting handle 224 drives the worm gear to rotate.

[0066] It should be noted that the lifting reducer 221 uses an SWL reducer, which is a common type of worm gear jack. It is mainly used to convert rotary motion into linear motion. The lifting reducer 221 drives the lead screw 225 on the lifting reducer 221 to operate. The lifting reducer 221 causes the lead screw 225 to move along its own axis, thereby realizing the lifting motion function and having a self-locking function.

[0067] The four corners of the platform 12 and the base 11 are all provided with a linkage support mechanism 3, which includes a swing arm 31, a support rod 32 and a second limiting nut 33;

[0068] The swing arm 31 is rotatably hinged to the bottom of the platform 12;

[0069] The support rod 32 is vertically mounted on the base 11. The top of the support rod 32 is hinged to the swing arm 31, and the bottom of the support rod 32 is inserted into the waist-shaped guide groove 111 of the base 11 by the limiting support of the second limiting nut 33.

[0070] The second limiting nut 33 is threaded onto the support rod 32, and the second limiting nut 33 is positioned to abut against the base 11.

[0071] The base 11 is provided with universal casters 112 at its four corners, and each universal caster 112 is equipped with a brake unit.

[0072] It should be noted that the working principle of the linkage support mechanism 3 is as follows: when the swing arm 31 rotates around the hinge point at the bottom of the platform 12, the support rod 32 will change its position and angle accordingly with the movement of the swing arm 31. Since the support rod 32 and the swing arm 31 are also hinged, the hinge points between the bottom of the platform 12 and the swing arm 31, and between the swing arm 31 and the support rod 32, are all fixed by screws. When adjustment is required, the screws are loosened first, and then the positions of the swing arm 31 and the support rod 32 are adjusted. After adjusting the position, the screws are tightened to fix it. Therefore, the support rod 32 can flexibly adapt to the posture changes of the swing arm 31 during the movement of the swing arm 31. At the same time, the bottom of the support rod 32 is inserted into the guide groove 111 of the base 11, which can limit and guide the movement direction of the support rod 32, so that the support rod 32 moves within a certain range along the guide groove 111 when changing. This structure helps the flipping assembly 21 to adjust the tilt angle of the platform 12 to meet different working requirements.

[0073] Working process: First, flip the front limit bar 134 on the guardrail assembly 13 upwards to open it. Then, place the air conditioner box to be tested on the platform 12. Adjust the height of the upper stop bar 133 according to the size of the air conditioner box. Then, flip the front limit bar 134 downwards to abut against the air conditioner box. Move the position of the front limit bar 134 laterally according to the size of the air conditioner box so that the guardrail assembly 13 completely covers and abuts against the air conditioner box, so that it does not shift. Next, start adjusting the flipping assembly 21 to adjust the platform 12 to a suitable angle position. At the same time, the linkage support mechanism 3 assists in adjusting the angle of the flipping assembly 21. After the adjustment is completed, adjust the platform 12 to a suitable height through the lifting assembly 22. When the specific position of the platform 1 is not accurate enough, the platform 1 can be moved to the accurate position through the universal rollers 112 on the four corners of the base 11 of the platform 1.

[0074] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
