Therefore, it is particularly important to conduct fire resistance tests on rolling shutter components. However, traditional fire resistance test devices often have problems such as uncontrollable test processes and inaccurate data collection.

[0003] In related technologies, the Chinese utility model patent with the publication number CN205403489U discloses a fire resistance test furnace for doors and rolling shutters, including a wall furnace and a specimen frame. The wall furnace is made of silicon carbide bricks, and the inner wall of the wall furnace sequentially includes a heat insulation layer, a refractory layer, and an anti-corrosion layer.

The moving frame includes a pair of parallel upper crossbars, a pair of parallel lower crossbars, vertical bars connecting the upper crossbars and the lower crossbars, connecting rods arranged between the upper crossbars and the lower crossbars, and a plurality of universal wheels arranged at the bottom of the lower crossbars. The vertical bars are fixedly connected to the upper crossbars and the lower crossbars. First sliding grooves for the sliding fit of the specimen frame are formed in the two upper crossbars and the two lower crossbars. Through grooves for the passage of the moving frame are formed in a plurality of the connecting rods. A driving component for driving the movement of the specimen frame is arranged on the lower crossbar. Fixed rods are arranged on both side walls of the wall furnace, and a fixing component for fixing the moving frame is arranged on the fixed rods. An operation platform is arranged behind the wall furnace, and a smoke suction hood is arranged above the wall furnace.

[0008] By adopting the above technical solution, the operator first moves the moving frame to one side of the test port through a plurality of universal wheels, places the specimen on the specimen frame, and the operator controls the driving component through the operation platform to drive the specimen frame to move in the first sliding groove and the through groove until the specimen frame abuts against the wall furnace. At this time, the specimen is placed into the test port and the fire resistance test can be started. After the test is completed, the operator reversely uses the driving component through the control platform to pull the specimen frame away from the wall furnace. After cooling, it is convenient for the operator to replace the specimen. In this way, the operator only needs to control the operation platform to complete the test, which saves manpower and material resources and improves efficiency at the same time. The smoke suction hood can timely absorb the smoke and dust generated by the test.

[0009] Preferably, the driving component includes a driving motor arranged on the outer end face of the lower crossbar and a threaded rod rotatably arranged in the lower crossbar. The specimen frame is in threaded fit with the threaded rod.

[0010] By adopting the above technical solution, the operator starts the driving motor through the operation platform. The driving motor rotates to drive the threaded rod to rotate. The threaded rod rotates to drive the specimen frame to move in the first sliding groove and the through groove, realizing the full mechanical driving of the movement of the specimen frame.

[0011] Preferably, a guide rod is arranged in the upper crossbar. The specimen frame is in sliding fit with the guide rod.

At this time, the vertical rod on the mobile frame is close to the fixed rod on the side wall of the wall furnace, and the fixed block enters the fixed slot. The mobile frame continues to move forward. At this time, the plug-in rod moves to the second sliding slot under the action of the fixed block and its inclined surface. At this time, the fixed spring is in a compressed state. When the vertical rod abuts against the fixed rod, the fixed block completely enters the fixed slot, and the plug-in rod pops out under the action of the fixed spring. The plug-in rod is inserted into the plug-in slot on the fixed block, completing the fixation of the mobile frame and facilitating the stable implementation of subsequent tests.

[0017] Preferably, a lever is provided on the plug-in rod, the lever is fixedly connected to the plug-in rod, the end surface of the lever is away from the plug-in rod and extends out of the vertical rod, and a third sliding groove for sliding cooperation of the lever is provided on the vertical rod.

The movement of the lever drives the plug-in rod to move. At this time, the fixed spring is in a compressed state. When the plug-in rod is completely out of the fixed slot, the specimen frame can be taken out.

[0019] Preferably, a buffer pad is provided on the end wall of the guide track close to the test port.

[0020] By adopting the above technical solution, the provision of the buffer pad is beneficial to reducing the rigid collision between the universal wheel and the guide rail, thereby improving the protection of the universal wheel and the guide rail.

In this way, the operator only needs to control the operating platform to complete the test, which saves manpower and material resources while also improving efficiency. The smoke hood can absorb the smoke generated by the test in time;

[0025] 2. The operator places the test piece on the test piece frame, guides the mobile frame onto the universal wheel guide roller track at the bottom of the mobile frame, and continues to push the mobile frame forward. At this time, the vertical rod on the mobile frame is close to the fixed rod on the side wall of the wall furnace, and the fixed block enters the fixed slot. The mobile frame continues to move forward. At this time, the plug-in rod moves into the second sliding slot under the action of the fixed block and its inclined surface. At this time, the fixed spring is in a compressed state.

The plug-in rod is inserted into the plug on the fixed block to complete the fixation of the mobile frame, which is convenient for the stable conduct of subsequent tests.

[0026] 3. After the test is completed, when the specimen frame needs to be taken out, the operator pushes the lever downward, and the lever moves in the third sliding groove.
