Refractory components are an important part of buildings.

[0024] 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 other different specific implementation manners.

[0025] Referring to Figures 1 - 6 , a water impact test device for a refractory member, comprising a moving part 1; a mounting frame 5 vertically mounted on the moving part 1; a first moving part 9 arranged on the mounting frame 5; a second moving part 7 connected to the first moving part 9 and configured to move under the drive of the first moving part 9; a water gun holder 8 mounted on the second moving part 7 and configured to move under the drive of the second moving part 7; and a test water gun 14 mounted on the water gun holder 8.

[0026] By controlling the first moving part 9, the movement of the water gun head in the horizontal direction can be accurately controlled to ensure that the water flow can accurately impact the specified part of the member.

[0027] The second moving part 7 moves along the horizontal direction under the drive of the first moving part 9 to meet specific test conditions.

[0028] The water gun holder 8 is mounted on the second moving part 7 and is used to drive the test water gun 14 to move, thereby adjusting the water spraying position.

[0029] The test water gun 14 sprays water flow towards the fire-resistant component according to the set pressure and flow rate, simulating the impact of the water gun on the building component during fire fighting and rescue in the real fire scene. By precisely controlling the working parameters of the water gun, the integrity and structural stability of the component after being impacted by heat and cooling water can be evaluated.

[0030] The moving part 1 includes: a base 15; universal wheels 6, which are installed on the base 15, and the number of the universal wheels 6 is three or more.

[0031] The base 15 serves as the support platform of the entire device. The three or more universal wheels 6 installed on it enable the device to move easily in all directions. The design of the universal wheels 6 not only provides 360-degree moving ability but also can be locked during positioning to ensure the stability of the device during the test. This means that the device can be quickly moved to the designated position and remain stable during the test, and the operator no longer needs to spend a lot of effort to carry or reposition the equipment, reducing the operation difficulty and labor intensity and improving the work efficiency.

[0032] The first moving part 9 includes: a first guide rail 903, which is installed on the installation frame 5, and a first rack is installed on the first guide rail 903; a first slider 902, which is movably installed on the first guide rail 903; a first motor 901, which is detachably installed on the first slider 902, and a first gear is installed on the first motor 901, and the first gear meshes with the first rack. Both the first motor 901 and the second motor 702 are self-locking motors.

[0033] A first rack is installed on the first guide rail 903 and meshes with the first gear on the first motor 901. Using the principle of mechanical transmission, it ensures that the first slider 902 has a high-precision positioning ability when moving on the guide rail.

[0034] The first moving part 9 can also adopt: a lead screw guide rail structure, which uses a spiral lead screw and a matching lead screw nut to rotate, thereby driving the slider to move in a straight line; a hydraulic or pneumatic cylinder drive system, which generates power by compressing liquid or gas and pushes the piston to move in a straight line in the cylinder; a direct drive linear motor, which directly converts electrical energy into the kinetic energy of linear motion; a worm and worm gear structure, which meshes the spiral teeth of the worm with the teeth of the worm gear to convert rotational motion into rotational or linear motion in the vertical direction, etc.

[0035] The second moving part 7 includes: a second guide rail 701, which is installed on the first slider 902, and a second rack is installed on the second guide rail 701; a second slider 703, which is movably installed on the second guide rail 701; a second motor 702, which is detachably installed on the second slider 703, and a second gear is installed on the second motor 702, and the second gear meshes with the second rack.

[0036] The rack two on the second guide rail 701 meshes with the gear two on the second motor 702 to form a precise transmission mechanism, which can ensure that the second slider 703 has high-precision positioning ability when moving on the second guide rail 701, and is suitable for mechanical systems that require high-precision operations.

[0037] The second moving part 7 can also adopt: a lead screw guide rail structure, which uses a spiral lead screw and a matching lead screw nut to rotate, thereby driving the slider to move linearly; 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; a worm and worm gear structure, which meshes the spiral teeth of the worm with the teeth of the worm gear to convert rotational motion into rotational or linear motion in the vertical direction, etc.

[0038] The first water pipe 13 is detachably mounted on the base 15 through the mounting bracket 2; the second water pipe 12 is connected to the first water pipe 13 through the first rotating head 3; the third water pipe 16 is connected to the second water pipe 12 through the second rotating head 4, and the test water gun 14 is connected to the third water pipe 16.

[0039] The first water pipe 13 is detachably mounted on the base 15 through the mounting bracket 2, which enables the entire water circulation system to be quickly assembled and adjusted according to test requirements. The second water pipe 12 is connected to the first water pipe 13 through the first rotating head 3, and the third water pipe 16 is connected to the second water pipe 12 through the second rotating head 4. The design of the first rotating head 3 and the second rotating head 4 further enhances the direction adjustability of the system, allowing the water flow to impact the test component from different positions.

[0040] The support member 11 is mounted on the base 15; the control box 10 is mounted on the support member 11, and the control box 10 is electrically connected to the first moving part 9 and the second moving part 7 respectively.

[0041] The control box 10 is the nerve center of the entire test device. The control box 10 contains electrical components and a control system, which can precisely control the movement of each component and the trajectory of the water flow of the water gun, reducing the need for manual operation, thereby reducing the operation complexity and potential error risk. The control box 10 is equipped with a user interface, such as buttons, switches or a touch screen, enabling the operator to easily set and adjust test parameters, enabling the operator to quickly familiarize with and master the operation process of the equipment, and allowing complex test operations without in-depth professional knowledge.

[0042] A right-angled tripod, with one right-angled side connected to the base 15 and the other right-angled side connected to the mounting frame 5.

[0043] The right-angle tripod utilizes the geometric stability of the triangle to provide solid support for the mounting frame 5 and its upper structure, ensuring the stability and reliability of the entire test device during the test, effectively enhancing the rigidity of the overall structure, and reducing deformation and vibration when subjected to external forces, which is essential for maintaining test accuracy, especially in tests that require long-term operation or withstand large impact forces.

[0044] During use, the test parameters are entered on the control box 10, and the fire resistance grade, width, height and other parameters of the test piece are input into the control box 10. Click "Run", and the control box 10 will automatically calculate the water gun movement speed according to the test parameters, and control the operation of the first motor 901 and the second motor 702 to drive the test water gun 14 to adjust its direction, thereby performing water impact on the refractory component.
