Description

Technical Field

[0001] This application belongs to the field of air conditioning installation and testing technology, and more specifically, it relates to an air conditioning bracket load-bearing testing device. Background Technology

[0002] In air conditioning installation projects, various supports and hangers are indispensable. Air conditioning ventilation ducts are generally suspended and fixed to the top of the building using supports and hangers.

[0003] There are various types of ventilation duct supports. Based on direction, one type is the vertical support, which hangs vertically from the top of the building to secure the ventilation duct at its lower end. Another type is the diagonal support, which also hangs vertically from the top of the building, usually used in pairs, symmetrically arranged in a V-shape, diagonally supporting the ventilation duct on both sides. Sometimes, vertical and diagonal supports are used in combination to further secure the ventilation duct. Based on the structure of the connection, one type uses bolts with connecting plates, while the other uses hinges with lug plates.

[0004] Before air conditioning installation, it's typically necessary to test the supports and hangers used to ensure their load-bearing capacity meets standards and doesn't compromise the quality of the installation. Currently, however, the testing of supports and hangers doesn't differentiate between different types; all are tested using the same method—direct axial tensile testing. This fails to accurately reflect the true stress conditions of the supports and hangers, leading to inaccurate test results. Furthermore, the testing equipment generally only accommodates one type of support and hanger connection structure, limiting its applicability to supports with multiple connection methods. Summary of the Invention

[0005] In view of this, the present application provides an air conditioner support bracket load-bearing testing device to solve the technical problems of existing testing devices being unable to accurately reproduce the actual stress condition of the support bracket and being unable to simultaneously accommodate supports brackets with multiple connection methods.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] On the one hand, an air conditioner bracket load-bearing testing device is provided, comprising:

[0008] The main frame is slidably equipped with a sliding seat, and side stops are provided on both sides of the sliding seat;

[0009] The gantry frame has corresponding top slots on the top of its two side frames and corresponding side slots on its sides. The gantry frame is slidably mounted relative to the main frame and can be switched between being mounted above the sliding seat and being offset at one end of the sliding seat by sliding. When the gantry frame is offset at one end of the sliding seat, the side slots are located on the side of the side frame away from the sliding seat.

[0010] The switching assembly includes a locking shaft, a hinge plate disposed on the side of the locking shaft, and a connecting seat; and

[0011] Two thrust mechanisms are respectively rotatably mounted on both sides of the gantry frame;

[0012] When the gantry frame spans above the sliding seat, both ends of the snap-fit ​​shaft snap into the corresponding top slots, so that the switching assembly is movably mounted on the top of the gantry frame and can rotate. One end of the vertical support to be tested is connected to the sliding seat. The switching assembly rotates to switch the hinge plate or the connecting seat to the other end of the vertical support to be tested, so that the vertical support to be tested is in a vertical use state. The two thrust mechanisms rotate to support the two ends of the snap-fit ​​shaft, so as to push the switching assembly to apply a pulling force to the vertical support to be tested.

[0013] When the gantry frame is biased at one end of the sliding seat, both ends of the snap-fit ​​shaft are snapped into the corresponding side slots, so that the switching component is limited to the side of the side frame away from the sliding seat and can be locked to rotate. One end of the inclined support bracket to be tested is connected to the sliding seat. The switching component rotates to switch the hinge plate or the connecting seat to the other end of the inclined support bracket to be tested and locks the switching component, so that the inclined support bracket to be tested is in the inclined pulling state. The two thrust mechanisms rotate to abut against the two side stops to push the sliding seat to apply a pulling force to the inclined support bracket to be tested.

[0014] In some embodiments, at least one end of the snap-fit ​​shaft is coaxially provided with a positioning disk, the positioning disk having a plurality of locking holes distributed circumferentially, the side frame having a locking pin hole located near the side snap-fit ​​groove, and when the snap-fit ​​shaft is snapped into the side snap-fit ​​groove, any of the locking holes is aligned with the locking pin hole.

[0015] In some embodiments, one end of the thrust mechanism is hinged to the gantry frame, and the other end is provided with an arc-shaped groove to limit the side stop or the snap-fit ​​shaft.

[0016] In some embodiments, the main frame is provided with rails on both sides, the two side frames of the gantry are sandwiched between the two sides of the main frame, and the inner sides of the two side frames are respectively provided with rollers that roll along the corresponding rails;

[0017] The main frame has multiple sets of positioning pin holes arranged along the track direction on its side, and the side frame has a set of positioning holes. The gantry can slide to align the positioning holes with any set of positioning pin holes.

[0018] In some embodiments, one side of the side frame is provided with a plurality of side slots arranged vertically.

[0019] In some embodiments, the top of the side frame is provided with a removable pressure plate that blocks the opening of the top slot.

[0020] In some embodiments, limiting supports are provided on both sides of the sliding seat, the limiting supports being adapted to restrict the thrust mechanism below and stop the thrust mechanism in alignment with the side stop bar.

[0021] In some embodiments, the hinge plate has a surface perpendicular to the snap-fit ​​shaft and a hinge hole at its center, and the positioning surface of the connecting seat is parallel to the snap-fit ​​shaft.

[0022] The beneficial effects of the air conditioner support and hanger load-bearing testing device provided in this application embodiment are as follows: Compared with the prior art, the air conditioner support and hanger load-bearing testing device in this application embodiment can simulate the actual stress situation of vertical supports and hangers and inclined supports and hangers when in use by moving the gantry and adjusting the position of the switching component on the gantry, thereby making the test more accurate; moreover, by rotating the switching component, the hinge plate or connecting seat can be switched to connect with the support and hanger, thereby accommodating supports and hangers with different connection methods and greatly expanding the scope of application.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" or "several" means two or more, unless otherwise explicitly specified.

[0035] Please refer to the following: Figures 1 to 5 The load-bearing capacity testing device for air conditioner brackets provided in this application will now be described. An air conditioner bracket load-bearing capacity testing device includes: a main frame 1, a gantry frame 2, a switching assembly, and two thrust mechanisms 4.

[0036] The main frame 1 is slidably equipped with a sliding seat 11, and side stops 12 are provided on both sides of the sliding seat 11. The thrust mechanism 4 can apply thrust to the sliding seat 11 through the side stops 12. Specifically, the sliding seat 11 can be installed on the main frame 1 in the form of a slide rail slider.

[0037] The two side frames of the gantry frame 2 have corresponding top slots 21 on their tops and corresponding side slots 22 on their sides. The gantry frame 2 is slidably mounted relative to the main frame 1 and can be switched between being mounted above the sliding seat 11 and offset from one end of the sliding seat 11 by sliding. When the gantry frame 2 is offset from one end of the sliding seat 11, the side slots 22 are located on the side of the side frame away from the sliding seat 11. Specifically, the gantry frame 2 is generally inverted U-shaped, and the two side frames of the gantry frame 2 can slide along the main frame 1 by means of a slide rail slider or by means of rollers 24 and rails 13. A connecting plate 8 can be provided between the two side frames of the gantry frame 2 to increase the overall strength.

[0038] The switching assembly has a snap-fit ​​shaft 3 and a hinge plate 31 and a connecting seat 32 located on the side of the snap-fit ​​shaft 3. The connecting surface of the connecting seat 32 is parallel to the snap-fit ​​shaft 3 and has multiple bolt holes, so that it can be connected to one end of the support. The plate surface of the hinge plate 31 is perpendicular to the snap-fit ​​shaft 3, and it can be hinged to one end of the support by bolts through the central bolt hole.

[0039] Two thrust mechanisms 4 are respectively rotatably mounted on both sides of the gantry 2, so that the two thrust mechanisms 4 can rotate to a horizontal position to push the side stop bar 12, or rotate to a vertical position to push the two ends of the snap-fit ​​shaft 3 of the switching component; the thrust mechanism 4 can be a hydraulic cylinder or a pneumatic cylinder.

[0040] When the gantry 2 spans above the sliding seat 11, both ends of the locking shaft 3 engage with the corresponding top locking groove 21, allowing the switching assembly to slide up and down and rotate within the top locking groove 21 on the top of the gantry 2. The vertical support 5 to be tested is vertical, with its lower end connected to the sliding seat 11. Based on the connection structure at the upper end of the vertical support 5 to be tested, the switching assembly is rotated to connect the hinge plate 31 or connecting seat 32 to the upper end of the vertical support 5 to be tested, so that the vertical support 5 to be tested is in a vertical operating state. The two thrust mechanisms 4 rotate to the vertical state, thereby supporting both ends of the locking shaft 3, and pushing the switching assembly upward to apply a pulling force to the vertical support 5 to be tested, simulating the weight of the air conditioning duct applied to the vertical support 5.

[0041] When the gantry 2 is offset at one end of the sliding seat 11, the two ends of the locking shaft 3 are respectively locked into the side slots 22 of the two side frames of the gantry 2, so that the switching component is limited to the side of the side frame away from the sliding seat 11 and can be locked to rotate. The lower end of the inclined support bracket 6 to be tested is connected to the sliding seat 11; according to the connection structure of the upper end of the inclined support bracket 6 to be tested, the switching component is rotated to switch the hinge plate 31 or the connecting seat 32 to the other end of the inclined support bracket 6 to be tested, and the switching component is locked to keep the position of the hinge plate 31 or the connecting seat 32 fixed, so that the inclined support bracket 6 to be tested is in an inclined use state. The two thrust mechanisms 4 are respectively rotated to a horizontal state to abut against the two side stops 12, so as to push the sliding seat 11 to apply a pulling force to the inclined support bracket 6 to be tested, simulating the situation where the weight of the air conditioning pipe is applied to the inclined support bracket 6.

[0042] Compared with the prior art, the air conditioner support and hanger load-bearing testing device of this application embodiment can simulate the actual stress conditions of the vertical support and hanger 5 and the inclined support and hanger 6 during use by moving the gantry 2 and adjusting the position of the switching component on the gantry 2, thereby making the test more accurate; moreover, by rotating the switching component, the hinge plate 31 or the connecting seat 32 can be switched to connect with the support and hanger, thereby accommodating supports and hangers with different connection methods and greatly expanding the scope of application.

[0043] Please see Figures 1 to 5 As a specific embodiment of the air conditioner bracket load-bearing testing device provided in this application, at least one end of the snap-fit ​​shaft 3 is coaxially provided with a positioning plate 33, the positioning plate 33 is circumferentially distributed with a plurality of locking holes 331, the side frame is provided with a locking pin hole 23, the locking pin hole 23 is located near the side slot 22, and when the snap-fit ​​shaft 3 is snapped into the side slot 22, any locking hole 331 is aligned with the locking pin hole 23.

[0044] In this embodiment, the position and angle of the hinge plate 31 or the connecting seat 32 can be adjusted by rotating the switching component, so that the inclined support bracket 6 is kept in an inclined state when installed between the switching component and the sliding seat 11; the angle of the switching component can be locked by inserting a locking pin into the aligned locking hole 331 and locking pin hole 23, so that the position of the hinge plate 31 or the connecting seat 32 is kept fixed, and the force on the inclined support bracket 6 during the test is the same as that in actual use.

[0045] Please see Figure 1 and Figure 2 As a specific embodiment of the air conditioner support and hanger load-bearing test device provided in this application, one end of the thrust mechanism 4 is hinged to the gantry 2, and the other end is provided with an arc-shaped groove to limit the side stop bar 12 or the clamping shaft 3.

[0046] In this embodiment, when the arc-shaped groove of the thrust mechanism 4 abuts against the side stop rod 12 or the snap-fit ​​shaft 3, the side stop rod 12 or the snap-fit ​​shaft 3 is limited in the arc-shaped groove, so as to prevent the thrust mechanism 4 from slipping and misaligning with the side stop rod 12 or the snap-fit ​​shaft 3 when the thrust mechanism 4 applies force.

[0047] Please see Figures 1 to 3 As a specific embodiment of the air conditioner support and hanger load-bearing test device provided in this application, the main frame 1 is provided with rails 13 on both sides, the two side frames of the gantry frame 2 are sandwiched between the two sides of the main frame 1, and the inner sides of the two side frames are respectively provided with rollers 24 that roll along the corresponding rails 13.

[0048] The main frame 1 has multiple sets of positioning pin holes 14 arranged along the direction of the track 13 on its side, and the side frame has a set of positioning holes 25. The gantry frame 2 slides so that the positioning holes 25 are aligned with any set of positioning pin holes 14.

[0049] In this embodiment, the gantry frame 2 moves left and right along the main frame 1 by rolling along the track 13 via rollers 24. When the gantry frame 2 is in place, locking pins are inserted into the aligned positioning holes 25 and positioning pin holes 14 to fix the gantry frame 2 in a position spanning above the sliding seat 11 or in a position offset from one end of the sliding seat 11.

[0050] Please see Figures 1 to 3 As a specific embodiment of the air conditioner bracket load-bearing testing device provided in this application, one side of the side bracket is provided with a plurality of side slots 22 arranged in the vertical direction.

[0051] In this embodiment, by inserting the switching component into the side slots 22 at different heights, the use of the inclined support bracket 6 at different tilt angles can be simulated, making the test closer to the actual use.

[0052] Please see Figures 1 to 3 As a specific embodiment of the air conditioner bracket load-bearing testing device provided in this application, the top of the side bracket is provided with a detachable pressure plate 26, which blocks the opening of the top slot 21. In use, the pressure plate 26 is first removed, then the end of the switching component clamping shaft 3 is inserted into the top slot 21, and then the pressure plate 26 is installed on the top of the side bracket.

[0053] In this embodiment, the pressure plate 26 can prevent the thrust mechanism 4 from pushing the switching component upward out of the top slot 21, thus avoiding accidental injury.

[0054] In a practical implementation, pressure plates 26 are detachably mounted on the top of both side frames, and the two pressure plates 26 respectively block the two ends of the switching component clamping shaft 3. Specifically, the pressure plates 26 can be detachably mounted on the top of the side frames by bolts.

[0055] Please see Figure 1 and Figure 2 As a specific embodiment of the air conditioner bracket load-bearing test device provided in this application, the sliding seat 11 is provided with limiting supports 111 on both sides. The limiting supports 111 are adapted to restrict the thrust mechanism 4 below and stop the thrust mechanism 4 in alignment with the side stop bar 12.

[0056] In this embodiment, when the thrust mechanism 4 tilts downward from a vertical position, it can be supported on the limiting support 111, thereby stopping in a horizontal position and aligning perfectly with the side stop bar 12, making it more convenient to use.

[0057] Please see Figure 4 and Figure 5 As a specific embodiment of the air conditioner bracket load-bearing testing device provided in this application, the surface of the hinge plate 31 is perpendicular to the snap-fit ​​shaft 3 and the center is provided with a hinge hole 311, and the positioning surface of the connecting seat 32 is parallel to the snap-fit ​​shaft 3.

[0058] In this embodiment, for a support bracket with an ear plate 7 at one end, the hinge plate 31 of the switching assembly can be hinged to the ear plate 7 of the support bracket using bolts, achieving the same connection method as in actual use, ensuring that the test is completely consistent with the actual use. For a support bracket with a connecting plate 8 at one end, the connecting plate 8 of the support bracket can be attached to the connecting seat 32 of the switching assembly and fixed with bolts, achieving the same connection method as in actual use, ensuring that the test is completely consistent with the actual use.

[0059] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
