Abstract
Description
Technical Field
[0001] This utility model relates to the field of building component testing technology, specifically to a loading and unloading system for fire resistance limit testing equipment of horizontal building components. Background Technology
[0002] With societal development, increasing material wealth and population density, the frequency of fires and the resulting damage are becoming increasingly severe. The flammability of building materials is a significant factor contributing to fire risk. Therefore, using materials with high fire resistance is a crucial strategy for reducing fire hazards, and fire performance testing must be conducted on building materials before they are put into use.
[0003] The fire resistance of building components is typically verified using a test combustion furnace. In fire tests, a simulated fire environment is established within the furnace according to the temperature and pressure conditions specified in the standards. The integrity, insulation, and other indicators of the building components are analyzed to assess their fire resistance. The test specimens are generally horizontal or vertical components. Horizontal components are often suspended in actual building use and have a relatively long horizontal length; therefore, their fire resistance under pressure is crucial to the safety of the entire building.
[0004] To ensure the ambient temperature for the experiment, the combustion furnace is generally enclosed on all sides, while the top is open for placing and removing samples. Because the combustion furnace is relatively tall and narrow inside, the sample needs to be raised to a sufficient height before being accurately placed or removed from the furnace. It is also important to avoid collisions between the sample and the furnace wall during the process, which is difficult to control. Furthermore, the sample placed in the furnace is prone to deformation during the experiment, which can cause the sample to shift and affect its positional relationship with the burner of the combustion furnace, thus affecting the accuracy of the experimental results.

Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.
[0026] Example
[0027] Please refer to Figures 1 to 3 This embodiment provides a loading and unloading system for fire resistance rating equipment of horizontal building components, including a support platform 10, which is located inside a sample combustion furnace and is used to support the sample; secondly, it includes a transfer mechanism, which includes a translation frame 70, a longitudinal frame 71, and a crane 72. The translation frame 70 is slidably connected to the ground so that it can move along the X-axis. The longitudinal frame 71 is located on the translation frame 70. The crane 72 is slidably connected to the longitudinal frame 71 so that it can move along the Y-axis. The crane 72 can move in the Z-axis direction, with the hook lifting and lowering along the Z-axis. The X-axis, Y-axis, and Z-axis are perpendicular to each other. The transfer mechanism is used to transfer the sample to the bearing platform 10. The third part includes a clamping mechanism, which includes a clamping beam 80 and multiple hydraulic clamping columns 81. The clamping beam 80 is used to slide and connect with the top of the sample combustion furnace. All the hydraulic clamping columns 81 are vertically arranged at the bottom of the clamping beam 80. The hydraulic clamping columns 81 are used to press down on the sample so that the sample is clamped between the hydraulic clamping columns 81 and the bearing platform 10.
[0028] The fire resistance rating test loading and unloading system for horizontal building components provided in this embodiment uses a bearing platform 10 to support the test sample and a transfer mechanism including a translation frame 70, a longitudinal frame 71, and a crane 72. The translation frame 70 is located directly above the top of the combustion furnace and is slidably connected to the ground along the X-axis. The longitudinal frame 71 is installed on the translation frame 70 along the Y-axis. The crane 72 is slidably connected to the longitudinal frame 71 along the Y-axis, thereby enabling the crane 72 to move independently along the X-axis and Y-axis at the top of the combustion furnace. The moving mechanism, combined with its own Z-axis moving hook, uses the hook to lift the sample, enabling the sample to be precisely displaced at the top of the combustion furnace. This effectively solves the problems of difficult operation and easy shaking and collision when loading or unloading samples into the combustion furnace. By setting up a clamping mechanism, the sample placed in the combustion furnace and falling onto the bearing platform 10 is longitudinally fixed to avoid the problem of its own displacement due to deformation during the test. By setting up a clamping beam 80 that is slidably connected to the combustion furnace, it can fully avoid the sample being lifted in, further avoiding collisions.
[0029] To further explain the specific structure of the translation frame 70, the translation frame 70 includes a translation beam 701 and four support legs 702; the translation beam 701 is horizontally positioned above the sample combustion furnace along the Y-axis direction, and the length of the translation beam 701 matches the furnace width in the same direction of the sample combustion furnace; the four support legs 702 are fixedly connected to the four corners of the translation beam 701 respectively, and the bottom end of the support legs 702 is slidably connected to the ground along the X-axis direction.
[0030] With the above configuration, the translation beam 701 can be horizontally positioned above the combustion furnace, and the four legs can effectively support the translation beam 701 without obstructing the combustion furnace. The translation beam 701 can also be moved outside the combustion furnace to hoist the sample located outside the furnace.
[0031] To further enhance the stability of the translation frame 70, the support legs 702 are inclined so that the translation beam 701 and any two support legs 702 can form a trapezoidal surface.
[0032] To further explain the specific structure of the support leg 702, the support leg 702 includes an outer rib 7021, an inner rib 7022, and multiple connecting ribs 7023; the top of the outer rib 7021 is connected to the corner of the translation beam 701; the top of the inner rib 7022 is connected to the long side of the translation beam 701, and the bottom is connected to the bottom of the corresponding outer rib 7021, so that the translation beam 701, the outer rib 7021, and the corresponding inner rib 7022 form a triangular frame; the two ends of the connecting rib 7023 are respectively connected to the corresponding outer rib 7021 and the corresponding inner rib 7022, and all the connecting ribs 7023 are arranged in parallel and at even intervals.
[0033] Through the above configuration, a triangular structure is formed by using the outer reinforcement 7021, the inner reinforcement 7022, and the translation beam 701 to improve the structural stability and strength. On this basis, by setting the connecting reinforcement 7023, a reinforcing skeleton is formed to further enhance the structural strength of the triangular structure.
[0034] To provide a specific explanation of the sliding connection structure between the support leg 702 and the ground, the bottom ends of the two support legs 702 located at the same end of the translation beam 701 are connected to a translation slide 73, which extends along the X-axis; a translation slide rail 74 is provided below the translation slide 73, which extends along the X-axis, and the distance between the two translation slide rails 74 is greater than the width of the sample combustion furnace in the Y-axis direction.
[0035] To improve the smoothness of the sliding fit and provide power, any one of the translation slide blocks 73 is equipped with a translation motor 75 and multiple moving wheels. The translation motor 75 is connected to the moving wheels for transmission. The moving wheels are located on the translation slide block 73. The translation slide block 73 is slidably connected to the translation slide rail 74 through the moving wheels.
[0036] To further explain the specific structure of the longitudinal transfer frame 71, the longitudinal transfer frame 71 includes a longitudinal transfer beam 711 and a longitudinal transfer slide 712. The longitudinal transfer beam 711 is horizontally arranged along the Y-axis and is cross-shapedly inserted with the translation beam 701. The longitudinal transfer slide 712 is slidably connected to the bottom of the longitudinal transfer beam 711, and the crane 72 is fixedly connected to the longitudinal transfer slide 712.
[0037] To prevent the clamping beam 80 from obstructing the sliding of the translation beam 701, the clamping beam 80 is arranged horizontally along the X-axis; the clamping beam 80 is located below the translation beam 701.
[0038] To further explain the sliding fit structure between the clamping beam 80 and the combustion furnace, the two ends of the clamping beam 80 are slidably connected to longitudinal slide rails 82, and the longitudinal slide rails 82 are fixedly connected to the top of the sample combustion furnace; the clamping beam 80 is equipped with a longitudinal motor 83 and a longitudinal track 84, the clamping beam 80 is connected to the longitudinal slide rails 82 through the longitudinal track 84, and the longitudinal motor 83 is drivenly connected to the longitudinal track 84.
