Description

Technical Field

[0001] The utility model relates to the field of refractory component tests, in particular to an adjusting component for refractory component tests. Background Technique

[0002] Refractory components refer to building components that have a certain time of stability, integrity, and heat insulation under standard fire test conditions. Refractory components are an important part of buildings. They can play a crucial role in the event of a fire, slowing down the spread of the fire and buying precious time for personnel evacuation and fire fighting and rescue. There are many types of refractory components, such as fire doors, fire windows, etc. After fire resistance tests on fire doors, fire windows and other refractory components, a water impact test needs to be carried out to test the reliability of refractory components when facing the impact of fire fighting water in an actual fire scene. In order to ensure the accuracy and representativeness of the water impact test, an adjusting component needs to be carefully set up during the test process to finely adjust the position, angle of the water gun, as well as the intensity and direction of the water flow.

[0003] In the prior art, when manually controlling the water gun for spraying, it is difficult to ensure the precise consistency of the water flow route. Due to the slight changes in the force of holding the water gun, the spraying angle, and the moving trajectory, it may lead to uneven water flow distribution, which in turn affects the stress condition on the surface of the component, posing a significant threat to the accuracy and reliability of the test results, and the time control is not precise enough, thus affecting the final evaluation conclusion. Therefore, this application provides an adjusting component for refractory component tests to meet the requirements. Content of the Utility Model

[0025] The present utility model will be further elaborated below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the protection scope of the present utility model.

[0026] The following illustrates the implementation manners of the present utility model through specific examples. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model.

[0027] Refer to Figures 1 - 8, An adjustment component for a refractory component test, including a first moving part 1 and a refractory component main body 16; a mounting frame 6 vertically mounted on the first moving part 1; a laser rangefinder 5 mounted on the mounting frame 6; a second moving part 7 arranged on the mounting frame 6; a third moving part 3 connected to the second moving part 7 and configured to move under the drive of the second moving part 7; a water gun holder 13 detachably mounted on the third moving part 3 and configured to move under the drive of the third moving part 3; a test water gun 2 mounted on the water gun holder 13, and a pressure sensor 9 is arranged on the test water gun 2.

[0028] The first moving part 1 serves as the base of the entire adjustment component and can provide horizontal movement. By adjusting the position of the equipment in the horizontal direction, it can ensure that the distance between the test water gun 2 and the refractory component main body 16 to be tested meets the test standards, thus guaranteeing the accuracy and consistency of the test.

[0029] The mounting frame 6 provides a stable support structure for other components. Its main function is to maintain the stability of the laser rangefinder 5 and the second moving part 7, so as to reduce the vibration and deviation that may occur during the movement and ensure the accuracy of the test.

[0030] The laser rangefinder 5 is used to accurately measure the distance between the test water gun 2 and the refractory component main body 16. The accurate measurement of this distance is very crucial. Through two laser rangefinders 5, it can directly affect the force and effect of the water flow hitting the refractory component main body 16. The accurate data provided by the laser rangefinder 5 can help the operator adjust the position of the test water gun 2 to ensure that the water flow can accurately hit the center or designated area of the refractory component main body 16.

[0031] The second moving part 7 and the third moving part 3 can drive the test water gun 2 to conduct a water spraying test along a predetermined route and adjust the position of the test water gun 2.

[0032] The water gun holder 13 is used to fix and support the first water pipe 14. The design of the water gun holder 13 takes into account the convenience of installation and disassembly for daily maintenance and water pipe replacement.

[0033] The pressure sensor 9 is used to monitor the pressure of the water flow in real time. The data feedback of the pressure sensor 9 ensures that the water flow hits the refractory component at a constant and appropriate pressure.

[0034] The first moving part 1 includes: a base 20; a wheel-mounted motor 17 mounted on the base 20, and the number of wheel-mounted motors 17 is four or more; a Mecanum wheel 18 mounted on the wheel-mounted motor 17, and the number of Mecanum wheels 18 is the same as the number of wheel-mounted motors 17.

[0035] The base 20 serves as the foundation of the entire test device, providing stable and firm support to ensure that the test device remains stable during operation, avoiding displacement or tilt caused by vibration or impact, thereby guaranteeing the accuracy and reliability of the test.

[0036] The Mecanum wheel 18 is mounted on the wheel motor 17. The Mecanum wheel 18 is a specially designed wheel that can achieve 360-degree movement in the plane without changing the direction of the vehicle body. It is very helpful for the test device to make fine position adjustments in a narrow or complex test environment. By precisely controlling the rotation speed and steering of each wheel motor 17, precise movement and positioning of the test device can be achieved.

[0037] The second moving part 7 includes: a first guide rail 701 mounted on the mounting frame 6, on which a first rack is mounted; a first slider 703 movably mounted on the first guide rail 701; a first motor 702 detachably mounted on the first slider 703, on which a first gear is mounted, and the first gear meshes with the first rack.

[0038] The first guide rail 701 provides a stable and reliable movement path for the entire second moving part 7. The first guide rail 701 ensures that the first slider 703 moving on it can move smoothly and accurately along the predetermined trajectory, which is crucial for ensuring the accuracy of the distance between the test water gun 2 and the fire-resistant component.

[0039] The first slider 703 can slide freely on the first guide rail 701 while carrying other components, such as the first motor 702. The good cooperation between the first slider 703 and the guide rail reduces friction and wear during movement, while ensuring the smoothness and accuracy of movement.

[0040] The first motor 702 is detachably mounted on the first slider 703. This design facilitates the maintenance and replacement of the motor. When the first motor 702 operates, the meshing relationship between the first gear and the first rack is converted into a linear movement of the slider along the guide rail, thereby driving the test water gun 2 to move.

[0041] The second moving part 7 can also be a worm and worm gear structure. By the meshing of the helical teeth of the worm and the teeth of the worm gear, rotational motion is converted into rotational or linear motion in the vertical direction; a hydraulic or pneumatic cylinder drive system, which generates power by compressing liquid or gas and pushes the piston to move linearly in the cylinder; a direct drive linear motor, which directly converts electrical energy into the kinetic energy of linear motion, etc.

[0042] The third moving part 3 includes: a second guide rail 301 installed on the first slider 703, on which a second rack is installed; a second slider 302 movably installed on the second guide rail 301; a second motor 303 detachably installed on the second slider 302, on which a second gear is installed, and the second gear meshes with the second rack. Both the first motor 702 and the second motor 303 are self-locking motors.

[0043] The second guide rail 301 provides a stable and reliable movement path for the entire moving part. The second guide rail 301 ensures that the second slider 302 moving on it can move smoothly and accurately along a predetermined trajectory.

[0044] The second slider 302 can slide freely on the second guide rail 301 while carrying other components such as the second motor 303.

[0045] When the second motor 303 operates, the meshing relationship between the second gear and the second rack is converted into a linear movement of the slider along the guide rail, thereby driving the test water gun 2 to move on a finer scale.

[0046] The second moving part 7 can also be a worm and worm gear structure. By the meshing of the helical teeth of the worm and the teeth of the worm wheel, the rotational movement is converted into a rotational or linear movement in the vertical direction; a hydraulic or pneumatic cylinder drive system, which generates power by compressing liquid or gas and pushes the piston to move linearly in the cylinder; a direct drive linear motor, which directly converts electrical energy into the kinetic energy of linear movement, etc.

[0047] The first water pipe 14 is detachably installed on the base 20 through the mounting bracket 4, and an automatic regulating valve 19 is provided on the first water pipe 14; the second water pipe 10 is communicated with the first water pipe 14 through the first rotating head 12; the third water pipe 21 is communicated with the second water pipe 10 through the second rotating head 8, and the test water gun 2 is communicated with the third water pipe 21.

[0048] The first water pipe 14 is detachably installed on the base 20, which facilitates the maintenance and replacement of the first water pipe 14. The main function of the first water pipe 14 is to convey the external water source to the test device. It carries the water flow and ensures that the water flow can be stably transmitted to the test water gun 2. An automatic regulating valve 19 is provided on the first water pipe 14, and the automatic regulating valve 19 can automatically adjust the size of the water flow according to needs, thereby precisely controlling the water pressure at the root of the test water gun 2 and ensuring the accuracy and repeatability of the test.

[0049] The second water pipe 10 is connected to the first water pipe 14 through the first rotating head 12, and the third water pipe 21 is connected to the second water pipe 10 through the second rotating head 8. This design of rotational connection enables the third water pipe 21 to rotate freely in space to adapt to the position adjustment of the test water gun 2, so as to accurately adjust the impact point of the water flow according to the test requirements. This flexible connection method is crucial for simulating the water flow impact direction and angle in different fire scenarios.

[0050] The support member 15 is installed on the base 20; the control box 11 is installed on the support member 15, and the control box 11 is electrically connected to the second moving part 7, the third moving part 3, the laser rangefinder 5, the automatic regulating valve 19, and the pressure sensor 9 respectively.

[0051] The support member 15 provides a stable and reliable installation platform for the control box 11. The support member 15 has a certain structural strength and rigidity to ensure that it can bear the weight of the control box 11 and its internal equipment during the test, while remaining stable and avoiding displacement or tilt caused by vibration or impact, thus ensuring the accuracy and reliability of the test.

[0052] The control box 11 is the nerve center of the entire test device. The control box 11 is equipped with an electrical control system and a data processing system inside. The function of the control box 11 is to centrally control and coordinate the work of each component to achieve the automation and precise control of the test process. For example, the control box 11 can adjust the positions of the second moving part 7 and the third moving part 3 according to the data provided by the laser rangefinder 5. At the same time, it can also adjust the automatic regulating valve 19 according to the feedback information of the pressure sensor 9 to control the size and speed of the water flow.

[0053] The right-angled tripod, one right-angled side is connected to the base 20, and the other right-angled side is connected to the mounting frame 6.

[0054] The right-angled tripod utilizes the stability principle of the triangle to provide a solid support for the mounting frame 6, ensuring the stability of the mounting frame 6 during the test, being able to effectively disperse the force from the mounting frame 6, transfer the force to the base 20, reduce the burden on a single component, and improve the durability and reliability of the entire test device.

[0055] Before the test, enter the test parameters on the control box, input parameters such as the fire resistance rating, width, and height of the specimen into the software, and click to run. The test device measures the distances L1 and L2 between the test water gun 2 and the main body 16 of the fire-resistant component respectively through two laser rangefinders 5, and calculates the angle θ between the water gun nozzle and the specimen: Angle θ between the test water gun 2 and the main body 16 of the fire-resistant component: By controlling the rotation of the Mecanum wheels, rotate the test device by θ to keep the test water gun 2 perpendicular to the main body 16 of the fire-resistant component. Then, control the longitudinal movement of the test device so that the distance between the water gun nozzle and the test piece is 6 m, and impact along the perimeter of the main body 16 of the fire-resistant component. Starting from any bottom corner of the test piece, move upward. After the water flow covers the perimeter of the main body 16 of the fire-resistant component, move the water flow in the vertical direction and impact at intervals of 305 mm until the entire width direction is impacted. Subsequently, move the water flow in the horizontal direction and impact at intervals of 305 mm until the entire height direction is covered. The path diagram of the water flow acting on the main body 16 of the fire-resistant component is as Figure 2 shown.

[0056] Move the test device horizontally to find the width boundary of the test piece. When the distance between the test device measured by the laser rangefinder 5 and the main body 16 of the fire-resistant component changes significantly, it indicates that the measurement point of the laser rangefinder 5 has exceeded the width range of the main body 16 of the fire-resistant component. Then, move the test device towards the center of the test piece by a distance of △L: L = (L 试件 - L) / 2, which can make the nozzle direction of the test water gun 2 be in the normal direction of the center of the test piece, thus realizing automatic centering. After centering is completed, the control software will automatically set the water spray pressure, the moving speed of the water gun, etc. according to the test parameters. After the water spray starts, control the motor to operate, drive the test water gun 2 to adjust the direction, and complete the water impact test.

[0057] During use, the Mecanum wheels 18 installed under the base 20 are respectively controlled by the motors on the wheels. One end of the first water pipe 14 can be connected to an external water source. The first water pipe 14 and the second water pipe 10 are connected through the first rotating head 12 and can rotate. An automatic regulating valve 19 is installed on the first water pipe 14, and the pressure at the root of the test water gun 2 can be adjusted by adjusting the water flow rate. The pressure sensor 9 can monitor the pressure at the root of the test water gun 2 in real time. The laser rangefinder 5 can measure the distance between the water impact test device and the test piece. By cooperating the laser rangefinder 5 with the Mecanum wheels 18, the test device can be adjusted so that the nozzle direction of the test water gun 2 is in the normal direction of the center of the test piece. The first slider 703 and the second slider 302 slide under the action of the first motor 702 and the second motor 303 respectively, and then drive the test water gun 2 to move.
