Description

Technical Field

[0001] The invention relates to the technical field of window opener testing, and in particular to a thrust measuring device and a measuring method for a heavy-duty push rod type window opener. Background Art

[0002] Heavy-duty push rod window openers are mechanical devices specially designed for opening and closing large or heavy windows. They are usually installed in industrial buildings, commercial facilities or places with special ventilation requirements, such as factories, warehouses, gymnasiums, etc. This type of window opener can provide a large thrust to ensure smooth operation even in the case of high wind pressure or heavy windows. Therefore, heavy-duty push rod window openers need to be tested for thrust before leaving the factory to ensure the safety of heavy-duty push rod window openers.

[0003] Publication No. CN118050110B discloses a window opener thrust detection device, which relates to the field of thrust detection technology, including: two connecting rods are symmetrically welded at the bottom of both ends of the force-bearing track, the head end parts of the two connecting rods are in abutment with the horizontal detection platform, and the two connecting rods are rotatably connected to a forwardly arranged inclined rod, and the tail ends of the two inclined rods are rotatably connected to two slip rings; when the force-bearing track slides backward, the two slip rings are driven to abut and contact with the rear end fixing blocks of the two longitudinal positioning shafts; a triangular guide strip is welded on the front side wall of the force-bearing track, and the guide wheel at the head end of the folding arm of the folding arm window opener moves forward to abut and contact the hypotenuse of the triangular guide strip to be plugged and combined with the force-bearing track.

[0004] Although the above-mentioned application and the prior art can save the trouble of manual operation before and after the detection, when the window opener is used for thrust detection in the above-mentioned application and the prior art, it is not convenient to simulate windows of different weights to perform thrust detection on the window opener, so the detection is one-sided. Moreover, although adding a counterweight block on the surface of the window or adding a water source inside the window can increase the overall weight of the window, it will cause the overall weight distribution of the window to be uneven and the weight will shift during the rotation of the window, which will cause errors in the thrust measurement results. Moreover, when the weight of the window is increased by using a water source, the air pressure inside the window will increase. In order to avoid the increase of the air pressure inside the window, it is usually reduced by opening a hole or using a pressure relief valve. However, opening a hole will cause the water source inside to be lost. The pressure relief valve will be used frequently during the actual detection process, which will cause the pressure relief valve to be damaged over time. Therefore, we propose a thrust measurement device and a measurement method for a heavy-duty push rod window opener. Summary of the invention

In order to avoid the increase of the air pressure inside the window, it is usually reduced by opening a hole or using a pressure relief valve, and opening a hole will cause the water source inside to be lost.

[0026] Compared with the prior art, the present invention provides a thrust measurement device and method for a heavy-duty push rod window opener, which has the following beneficial effects:

[0027] 1. The thrust measuring device and method of the heavy-duty push rod window opener start the suction pump by using the water supply component in conjunction with the simulation frame.

[0050] The water supply component 3 is arranged inside the measuring box 2 and is used to supply water to the inside of the simulation frame 24, so as to increase the overall weight of the simulation frame 24;

[0051] The forming component 4 is arranged on one side of the simulation frame 24 and is used to squeeze the water source inside the simulation frame 24 to prevent the water source inside the simulation frame 24 from shaking during the detection process;

[0052] The pressure relief component 5 is arranged inside the simulation frame 24 to prevent the internal air pressure of the simulation frame 24 from increasing when the molding component 4 squeezes the water source, thereby causing damage to the simulation frame 24;

[0053] When the window opener needs to be tested for thrust, the window opener to be tested is installed inside the mounting groove 11, and then the rear end of the window opener is installed inside the mounting frame 242 through screws and bolts, so that the rear end of the window opener is hinged with the mounting frame 242, and then the dynamometer 241 is connected to the window opener, and the window opener is started to push the simulation frame 24, and then the thrust of the window opener pushing the simulation frame 24 is measured by the dynamometer 241, so as to measure the thrust generated by the window opener when pushing the simulation frame 24;

[0054] For specific embodiment 2, please refer to Figures 1 to 8 According to a thrust measuring device for a heavy-duty push rod type window opener provided in the first specific embodiment, this embodiment provides a further technical solution:

[0055] A water tank 13 is provided inside the support platform 1, and a tilting block 131 is fixedly connected inside the water tank 13. A water inlet channel 12 is provided on one side of the water tank 13, and a screw block 121 is threadedly connected to one end of the water inlet channel 12 away from the water tank 13. The water supply component 3 includes a suction pump 31 fixedly connected to the inside of the measuring box 2, a water inlet pipe 311 is provided at the bottom of the suction pump 31, and the water inlet pipe 311 is provided inside the water tank 13. A water outlet pipe 312 is provided at the top of the suction pump 31, and a bellows 32 is fixedly connected to one end of the water outlet pipe 312 away from the suction pump 31, and a one-way valve 321 is provided on the surface of the bellows 32, and one end of the bellows 32 away from the water outlet pipe 312 is fixedly connected to the top of the simulation frame 24, and a drain pipe 243 is fixedly connected to the bottom of the simulation frame 24, and a solenoid valve 244 is provided on the surface of the drain pipe 243;

[0056] When the overall weight of the simulation frame 24 needs to be increased, the suction pump 31 is started, and the suction pump 31 transports the water in the water tank 13 to the water outlet pipe 312 through the water inlet pipe 311, and then transports the water source to the inside of the simulation frame 24 through the bellows 32 and the one-way valve 321, so that the overall weight of the simulation frame 24 is increased, and then the window opener can perform thrust tests on simulation frames 24 of different weights, so that the test results are more comprehensive. After the test is completed, the solenoid valve 244 is opened to allow the water flow inside the simulation frame 24 to flow back to the water tank 13 again through the drain pipe 243;

[0057] For specific embodiment 3, please refer to Figures 1 to 10 According to the thrust measuring device of a heavy-duty push rod type window opener provided in the second specific embodiment, this embodiment provides a further technical solution:

[0058] The molding assembly 4 includes a support frame 41 fixedly connected to one side of the simulation frame 24, a driving cylinder 411 is fixedly connected inside the support frame 41, a telescopic rod 412 is differentially connected to the output end of the driving cylinder 411, a U-shaped frame 42 is fixedly connected to the end of the telescopic rod 412 away from the driving cylinder 411, a sealing extrusion plate 421 is fixedly connected to the end of the U-shaped frame 42 away from the telescopic rod 412, the sealing extrusion plate 421 is slidably connected to the inside of the simulation frame 24, and the sealing extrusion plate 421 is in close contact with the inside of the simulation frame 24, and the molding assembly 4 also includes a pressure relief hole 43 opened on the top of the simulation frame 24;

[0059] When the water source inside the simulation frame 24 needs to be formed into a plane, the driving cylinder 411 is started, and the driving cylinder 411 drives the U-shaped frame 42 to move through the telescopic rod 412, so that the U-shaped frame 42 drives the sealing extrusion plate 421 to move inside the simulation frame 24. As the sealing extrusion plate 421 moves, the water source inside the simulation frame 24 is squeezed by the sealing extrusion plate 421 and moves, so that the water source inside the simulation frame 24 gradually forms a plane, thereby ensuring that the total weight of the water source inside the simulation frame 24 will not flow when the simulation frame 24 rotates, so that the weight of the water source inside the simulation frame 24 is evenly distributed, thereby ensuring the accuracy of subsequent thrust measurement;

[0060] For specific example 4, please refer to Figures 1 to 12 According to the thrust measuring device of a heavy-duty push rod type window opener provided in the specific embodiment 3, this embodiment provides a further technical solution:

[0061] The pressure relief component 5 includes a sliding groove 51 provided on the inner wall of the simulation frame 24, a semi-arc groove 511 is provided inside the sliding groove 51, a floating plate 52 is slidably connected inside the sliding groove 51, a semi-arc block 521 is fixedly connected to the surface of the floating plate 52, a blocking column 522 is fixedly connected to the top of the floating plate 52, and the shape of the blocking column 522 is adapted to the shape of the pressure relief hole 43, a control panel 21 is provided on one side of the measuring box 2, a through groove 22 is provided on one side of the measuring box 2 and at the bottom of the control panel 21, and the through groove 22 can connect the heavy-duty push rod type window opener to be tested with the simulation frame 24;

[0062] It should be noted that the blocking column 522 and the pressure relief hole 43 are on the same vertical horizontal plane. When the blocking column 522 is rising, the blocking column 522 can block the pressure relief hole 43, and an M-shaped floating block is provided at the bottom of the floating plate 52. When the simulation frame 24 rotates, the M-shaped floating block can keep the floating plate 52 in a horizontal state. When the simulation frame 24 rotates, the semi-arc groove 511 and the semi-arc block 521 will not affect the small-range deflection of the floating plate 52, and the floating plate 52 and the semi-arc block 521 are made of foam plastic boards and can float on the top of the water surface.

[0063] When it is necessary to relieve the pressure inside the simulation frame 24, the driving cylinder 411 is started, and the driving cylinder 411 drives the U-shaped frame 42 to move through the telescopic rod 412, so that the U-shaped frame 42 drives the sealing extrusion plate 421 to move inside the simulation frame 24. With the movement of the sealing extrusion plate 421, the water source inside the simulation frame 24 gradually forms a plane. During the extrusion process, the excess gas is discharged from the pressure relief hole 43, thereby relieving the pressure of the air inside the simulation frame 24. With the rise of the water level, the floating plate 52 moves inside the sliding groove 51. When the water level continues to rise, the blocking column 522 blocks the pressure relief hole 43, so that the water source inside the simulation frame 24 will not leak from the pressure relief hole 43 when the simulation frame 24 rotates. This not only effectively avoids the increase of the internal air pressure of the simulation frame 24, but also prevents the internal water source of the simulation frame 24 from being exposed from the pressure relief hole 43 when the simulation frame 24 rotates during subsequent measurement, thereby affecting the accuracy of the thrust measurement of the window opener.

[0064] Specific embodiment 5, the present invention also provides a method for measuring the thrust of a heavy-duty push rod type window opener, the method specifically comprising the following steps:

[0065] Step 1, install the window opener to be tested inside the mounting groove 11, connect the rear end of the window opener to the mounting frame 242, and then connect the dynamometer 241 to the window opener;

[0066] Step 2: When it is necessary to test windows of different weights, water is delivered to the interior of the simulation frame 24 through the water delivery component 3, so that the overall weight of the simulation frame 24 increases;

[0067] Step 3: When the weight distribution inside the simulation frame 24 needs to be uniform, the water source inside the simulation frame 24 is made into a plane through the forming component 4 to avoid the shaking of the water source during the subsequent force measurement, which may affect the force measurement accuracy;

[0068] Step 4: When the pressure inside the simulation frame 24 needs to be relieved, the pressure relief component 5 is driven by the molding component 4 so that the pressure relief component 5 can release the air pressure inside the simulation frame 24 .

[0069] Working principle: When in use, open the screw block 121, and then transport the external water source to the water tank 13 through the water inlet channel 12, and then restore the screw block 121 to its initial state to ensure that external dust will not enter the water tank 13 through the water inlet channel 12, and then install the window opener to be tested inside the mounting groove 11, and then install the tail end of the window opener inside the mounting frame 242 through screws and bolts, so that the tail end of the window opener is hinged with the mounting frame 242, and then connect the dynamometer 241 to the window opener. When it is necessary to increase the overall weight of the simulation frame 24, start the suction pump 31, and the suction pump 31 transports the water in the water tank 13 to the outlet pipe 312 through the water inlet pipe 311, and then passes through the bellows 32 and the one-way valve 3 21 transports the water source to the inside of the simulation frame 24, so that the overall weight of the simulation frame 24 is increased, so that the window opener can perform thrust tests on simulation frames 24 of different weights, so that the test results are more comprehensive. When it is necessary to form a plane for the water source inside the simulation frame 24, the driving cylinder 411 is started, and the driving cylinder 411 drives the U-shaped frame 42 to move through the telescopic rod 412, so that the U-shaped frame 42 drives the sealing extrusion plate 421 to move inside the simulation frame 24. As the sealing extrusion plate 421 moves, the water source inside the simulation frame 24 is squeezed by the sealing extrusion plate 421 and moves, so that the water source inside the simulation frame 24 gradually forms a plane, thereby ensuring that the overall weight of the water source inside the simulation frame 24 is not too large when the simulation frame 24 rotates. No flow will be generated, so that the weight of the water source inside the simulation frame 24 is evenly distributed, so as to ensure the accuracy of the subsequent thrust measurement. When it is necessary to relieve the pressure inside the simulation frame 24, the driving cylinder 411 is started, and the driving cylinder 411 drives the U-shaped frame 42 to move through the telescopic rod 412, so that the U-shaped frame 42 drives the sealing extrusion plate 421 to move inside the simulation frame 24. With the movement of the sealing extrusion plate 421, the water source inside the simulation frame 24 gradually forms a plane. During the extrusion process, the excess gas is discharged from the pressure relief hole 43, thereby relieving the pressure of the air inside the simulation frame 24. With the rise of the water level, the floating plate 52 moves inside the sliding groove 51. When the water level continues to rise, the blocking column 522 opens the pressure relief hole 43. Blockage prevents the water inside the simulation frame 24 from leaking from the pressure relief hole 43 when the simulation frame 24 rotates, which not only effectively avoids the increase of the air pressure inside the simulation frame 24, but also prevents the water inside the simulation frame 24 from leaking from the pressure relief hole 43 when the simulation frame 24 rotates in subsequent measurements, thereby affecting the accuracy of the thrust measurement of the window opener. The window opener is then started to push the simulation frame 24, and the thrust of the window opener pushing the simulation frame 24 is measured by the dynamometer 241, so as to measure the thrust generated by the window opener when pushing the simulation frame 24. After the detection is completed, the solenoid valve 244 is opened to allow the water flow inside the simulation frame 24 to flow back to the sink 13 through the drain pipe 243 again, so as to form a cycle, thereby preventing water resources from being wasted.

[0070] The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0071] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0072] Parallel: The parallelism defined in this application is not limited to absolute parallelism. This definition of parallelism can be understood as basic parallelism, which allows for non-absolute parallelism due to factors such as assembly tolerance, design tolerance, and the influence of structural flatness. Small angular errors are allowed. For example, an assembly error range of less than 10 degrees can be understood as a parallel relationship.

[0073] Vertical: The verticality defined in this application is not limited to an absolute vertical intersection relationship (angle of 90 degrees). It allows for non-absolute vertical intersection relationships caused by factors such as assembly tolerance, design tolerance, and influence of structural flatness. It also allows for errors in a small angle range. For example, the assembly error range of 80 to 100 degrees can be understood as a vertical relationship.

[0074] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
