[0084] Preferably, the stroke of the hydraulic cylinder is 0mm to 1000mm, which means that the piston rod 46 of the hydraulic cylinder can move from the fully retracted position (stroke of 0mm) to the fully extended position (stroke of 1000mm). This parameter (0mm to 1000mm) describes the maximum linear motion range that the hydraulic cylinder can provide.

[0085] In one embodiment, the mobile vehicle 3 further includes an inclined support member 48, which is disposed on the vehicle body device 5 and is used to obliquely support the fixed bracket device 8 and / or the movable bracket device 44.

[0086] Preferably, the inclined support member 48 is a steel column.

[0087] Reference Figures 15 to 18 In this embodiment, the fixed bracket device 8 and the movable bracket device 44 are arranged adjacent to each other and have a common outer frame structure 49. One end of the inclined support member 48 is connected to the outer frame structure 49 and the other end is connected to the vehicle body 36.

[0088] Reference Figure 19 Preferably, the number of the drive wheel 39, the support wheel 40, the fixed bracket 9, the support column 42, the hydraulic cylinder, the piston rod 46, the movable bracket 45, the support platform, and the inclined support member 48 are all two, and they are symmetrically arranged on both sides of the vehicle body 36.

[0089] One hydraulic cylinder is installed on each of the left and right sides of the vehicle body 36, and each hydraulic cylinder can output a maximum vertical upward lifting force of ten tons.

[0090] In one embodiment, the hydraulic cylinder has two operating states: (1) The first state is the hydraulic cylinder being filled with oil: When the fire resistance test frame 2 needs to be lifted, the hydraulic cylinder is filled with oil, and the piston rod 46 drives the movable bracket 45 to rise. The second limiting groove 47 of the movable bracket 45 supports the third support column 34 of the fire resistance test frame 2, and finally lifts the fire resistance test frame 2.

[0091] (2) The second state is the unloading state of the hydraulic cylinder: Once the movable bracket 45 has completed its lifting purpose, the hydraulic cylinder releases oil, the piston rod 46 moves downward, and drives the movable bracket 45 to retract.

[0092] ( Figure 21 → Figure 23 → Figure 23Through the movable bracket device 44 of the present invention, the fire resistance test frame 2 on the vehicle body 36 can be transferred from the support structure 7 and the fixed bracket 9 to the support member 4 of the fire resistance test furnace 1 for fixation (wherein, the support member 4 of the fire resistance test furnace 1 can support the first pillar 22 of the fire resistance test frame 2).

[0093] The cavity 21 of the fire resistance test frame 2 is used to place the test sample (such as fire door, fire window, fire shutter, firewall, etc.), and then the fire resistance limit performance of the test sample is tested through the fire resistance test furnace 1.

[0094] (Reference Figure 21 → Figure 19 → Figures 1 to 23 Through the movable bracket device 44 of the present invention, the refractory test frame 2 fixed on the support member 4 of the refractory test furnace 1 can be transferred to the support structure 7 and the fixed bracket 9 of the vehicle body 36 for fixation. After that, the mobile vehicle 3 will transfer the refractory test frame 2 to another place.

[0095] Another objective of this invention is to provide an operating method to scientifically guide people in using the supporting equipment to improve the installation or removal efficiency of the fire resistance test frame with the test sample.

[0096] Reference Figure 21 An operating method, based on the aforementioned fire resistance performance testing apparatus, includes the following steps: S1. Using a crane to hook the lifting lug hole 28 of the lifting lug device 23, the fire resistance test frame 2 with the test sample is hoisted onto the support structure 7 and fixed bracket 9 of the mobile vehicle 3. S2. Through the program of the power control system of the mobile vehicle 3, the mobile vehicle 3 is controlled to move automatically towards the front of the refractory test furnace 1. After the mobile vehicle 3 moves to the set position in front of the refractory test furnace 1, it stops moving. Preferably, the set position is "0.5m to 1.0m away from the front of the refractory test furnace". S3. Under the control of the hydraulic control system of the mobile vehicle 3, the hydraulic cylinder of the mobile vehicle 3 enters the oiling state, causing the movable bracket 45 of the mobile vehicle 3 to rise and lift the third pillar 34 of the fire resistance test frame 2 on the mobile vehicle 3 (refer to...). Figure 23 ); S4. The power control system of the mobile vehicle 3 controls the mobile vehicle 3 to move to the furnace opening of the refractory test furnace 1, and ensures that the first pillar 22 of the refractory test frame 2 is directly above the support member 4 (refer to...). ​ ); S5. Under the control of the hydraulic control system of the mobile vehicle 3, the hydraulic cylinder of the mobile vehicle 3 enters the oil unloading state, so that the refractory test frame 2 supported by the movable bracket 45 of the mobile vehicle 3 gradually descends until the first pillar 22 of the refractory test frame 2 is connected to the support member 4 of the refractory test furnace 1. S6. Under the program control of the power control system, the mobile vehicle 3 detaches from the refractory test frame 2 and leaves the furnace opening range of the refractory test furnace 1. S7. Complete the automatic installation of the fire resistance test frame 2; S8. Using the refractory test furnace 1, the refractory performance of the sample under test is tested. S9. After the fire resistance performance test of the sample is completed, the power control system of the mobile vehicle 3 is used to control the mobile vehicle 3 to move automatically to the fire resistance test furnace 1, so that the support structure 7 is just below the fire resistance test frame 2, and the second limiting groove 47 of the movable bracket 45 is just below the third pillar 34 of the fire resistance test frame 2. S10. The hydraulic cylinder of the mobile vehicle 3 enters the oiling state under the control of the hydraulic control system of the mobile vehicle 3, so that the movable bracket 45 of the mobile vehicle 3 rises up, lifts the refractory test frame 2 on the refractory test furnace 1, and ensures that the first pillar 22 of the refractory test frame 2 is higher than the top of the support member 4. S11. Under the program control of the power control system, the mobile vehicle 3 leaves the furnace opening range of the refractory test furnace 1 and stops moving at a set distance (e.g., 0.5m to 1.0m) from the refractory test furnace 1. S12. The hydraulic cylinder of the mobile vehicle 3, under the control of the hydraulic control system of the mobile vehicle 3, enters the oil unloading state, so that the fire resistance test frame 2 supported by the movable bracket 45 of the mobile vehicle 3 gradually descends, until the second pillar 33 of the fire resistance test frame 2 abuts against the first limiting groove 43 of the fixed bracket 9, and until the bottom of the fire resistance test frame 2 abuts against the support structure 7. S13. The power control system of the mobile vehicle 3 controls the mobile vehicle 3 to transfer the fire resistance test frame 2 to the target location (e.g., after arriving at the initial location, the fire resistance test frame 2 can be lifted off the mobile vehicle 3 by a crane). S14, The mobile vehicle 3 completes the task of transferring the fire resistance test frame 2.

[0097] Preferably, the fire resistance test of the sample under test in this invention is carried out in a laboratory, that is, the operating space is relatively limited, and the mobile vehicle of this invention can play a good role in transferring the fire resistance test frame.

[0098] (Note: The previous method of transferring the refractory test frame using a crane throughout the entire process had the following disadvantages: ① Using a crane throughout the entire process poses certain safety hazards. The sample being tested needs to be supported by personnel during the movement, and there is a risk of breakage of the lifting equipment. Accidents such as bumps and crushes are also likely to occur during the movement. When moving the refractory test frame to the refractory test furnace, there is also a risk of collision between the refractory test frame and the refractory test furnace, resulting in a relatively high safety risk; ② Using a crane to move the refractory test frame generally requires the site to be equipped with a 10-ton crane. The requirements for the height of the site (including the installation height of the crane) and the setting of load-bearing columns are also relatively high, making the construction of such laboratories more difficult.) In one embodiment, the present invention has the following advantages: (1) The support member on the refractory test furnace of the present invention facilitates the fixing or detachment of the refractory test frame. The support member is designed to be inclined upward. When the refractory test frame is fixed on the support member, the refractory test frame can be self-locked to the furnace mouth of the refractory test furnace by gravity, avoiding the need for a complex refractory test frame locking system. The support member and the refractory test frame support column of the present invention facilitate the automatic fixing of the refractory test frame to the refractory test furnace by a mobile vehicle and facilitate the automatic removal of the refractory test frame from the refractory test furnace by a mobile vehicle. (2) The fire resistance test frame of the present invention is equipped with a lifting lug device, which is beneficial for hoisting by a crane (during the preparation stage). In addition, the fire resistance test frame of the present invention has a reasonable structural design and requires relatively little space, which can meet the needs of multiple frames to be installed, maintained and tested in rotation under small site conditions.

[0099] (3) The mobile vehicle of the present invention can not only automatically install the refractory test frame onto the refractory test furnace, but also automatically remove the refractory test frame from the refractory test furnace, and can transport the refractory test frame smoothly (keeping it in a vertical position during transport). The hydraulic cylinder of the mobile vehicle of the present invention, under the control of the hydraulic control system, can provide a lifting force of not less than ten tons, which can easily realize the lifting and unloading operations of the refractory test frame. Under the program control of the power control system, the mobile vehicle of the present invention can automatically move forward / backward. The power control system, in conjunction with the hydraulic control system, can smoothly complete the installation and removal of the refractory test frame at the destination.

[0100] (4) The present invention utilizes a mobile vehicle to automatically install the refractory test frame onto or remove it from the refractory test furnace. The installation and removal process does not require human intervention, which greatly reduces the safety risks during manual operation and can reduce operation time and improve operation efficiency.

[0101] Other aspects of the supporting device and operating method for fire resistance testing described in this invention can be found in the prior art and will not be repeated here.

[0102] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
