Description

Technical Field

[0001] This utility model relates to the field of fire fighting and rescue simulation training technology, specifically a support leg assembly for fire trucks operating on elevated platforms in combat simulation training. Background Technology

[0002] Aerial platform fire trucks are specialized vehicles used for firefighting and high-altitude rescue in high-rise buildings. They effectively address the difficulties and dangers encountered in firefighting and rescue operations in high-rise buildings, improving efficiency and safety. However, in routine training of rescue personnel, using actual aerial platform fire trucks may pose potential risks due to improper equipment operation or emergency response, potentially increasing wear and tear on the equipment. Current technology typically employs live-fire training devices to simulate real-world rescue operations with aerial platform fire trucks. This significantly reduces vehicle wear and tear, ensures personnel safety, and achieves capacity building training for rescue teams in an energy-efficient and environmentally friendly manner.

[0003] However, the existing fire-fighting aerial platform simulation platforms have limited ability to simulate real aerial platform fire trucks, and their stability and reliability are not high.

[0004] Therefore, how to make the aerial platform fire truck training device closely resemble actual combat rescue simulation training, effectively improve its reliability, ensure training safety, and enhance training effectiveness has become an urgent problem to be solved in this field. Summary of the Invention

[0005] This utility model aims to provide a leg assembly for live-fire simulation training of fire trucks with aerial platforms. This solution can effectively compensate for the tilt angle deviation between the fire truck body and the ground, ensure that the legs can be vertically supported even on non-horizontal ground, improve the adaptability of the legs to complex terrain in simulation training, and ensure the stability and reliability of the entire structure. It can effectively overcome the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model provides an outrigger assembly for live-fire simulation training of fire trucks operating from elevated platforms. The assembly includes a fire truck body, an active boom, and a support sleeve. A connecting seat is fixedly installed on the outer edge of the fire truck body. A connecting arm is rotatably installed at the end of the connecting seat away from the fire truck body. A first mounting seat and an active boom are fixedly installed at the end of the connecting arm away from the fire truck body. A first telescopic cylinder is rotatably installed at the end of the first mounting seat away from the connecting arm. A second mounting seat is fixedly installed at the end of the active boom away from the connecting arm. A second telescopic cylinder is provided at the end of the second mounting seat away from the connecting arm. A mounting sleeve is provided at the output end of the first and second telescopic cylinders. A support sleeve is fixedly installed at the end of the mounting sleeve away from the connecting seat. A support column is slidably connected to the inner edge of the support sleeve.

[0007] Preferably, the first mounting base and the first telescopic cylinder are connected by a threaded first adjusting bolt, and the output end of the first telescopic cylinder is rotatably mounted to the mounting sleeve.

[0008] Through the above technical solution, the first adjusting bolt can adjust the connection angle between the first telescopic cylinder and the first mounting base, compensate for the tilt angle deviation between the fire truck body and the ground, and ensure that the outrigger can be vertically supported even on non-horizontal ground. The rotational connection between the output end of the first telescopic cylinder and the mounting sleeve allows the support sleeve to automatically adjust its posture according to the terrain, avoid stress concentration of the outrigger caused by rigid connection, and improve the adaptability of the outrigger to complex terrain in simulated training.

[0009] Preferably, a third adjusting bolt is threadedly connected between the second mounting base and the second telescopic cylinder, a connecting block is fixedly installed at the output end of the second telescopic cylinder, the connecting block and the mounting sleeve are rotatably installed, and a second adjusting bolt is provided between the connecting arm and the active arm.

[0010] Through the above technical solution, the second adjusting bolt can adjust the angle between the active arm and the connecting arm to simulate the different spans when the outriggers of the fire truck are deployed. The third adjusting bolt is used to adjust the installation angle of the second telescopic cylinder, and works with the first telescopic cylinder to realize the three-dimensional position adjustment of the outriggers. The rotating connection between the connecting block and the mounting sleeve allows the output end of the second telescopic cylinder to swing synchronously with the support sleeve.

[0011] Preferably, an adjusting rod is provided at the connection between the active arm and the mounting sleeve, and an adjusting seat is rotatably installed at the end of the support column away from the support sleeve.

[0012] Through the above technical solution, the adjusting rod can finely adjust the relative position of the mounting sleeve and the active arm, compensate for the cumulative error when the multi-section arm is deployed, ensure that the support column is vertically grounded, and allow the rotating installation of the adjusting seat and the support column to adapt to the ground slope within a certain range of the support plate's rotation axis, simulating the outrigger support state of a fire truck on complex terrains such as slopes and steps, thereby improving the realism of the training scenario.

[0013] Preferably, a rotating rod is provided at the connection between the adjusting seat and the support column, and a support plate is fixedly installed at the end of the adjusting seat away from the support column.

[0014] Through the above technical solution, the rotating rod allows the adjusting seat to rotate around the axis of the support column. When the support plate contacts the irregular ground, it can automatically adjust its posture to increase the contact area and prevent the outriggers from slipping.

[0015] Preferably, a sliding groove is provided at the inner edge of the support sleeve, a first positioning hole is provided through the outer edge of the support sleeve, and a second positioning hole is provided through the outer edge of the support column, wherein the first positioning hole and the second positioning hole correspond one-to-one.

[0016] The above technical solution allows for manual adjustment of the support column's height relative to the ground, enabling the support column to slide within the support sleeve. Furthermore, the corresponding design of the first and second positioning holes allows for the insertion of positioning bolts to fix the height of the support column, preventing height drift caused by vibration and ensuring the stability of the outrigger's position during training.

[0017] Preferably, a positioning bolt is threaded between the first positioning hole and the second positioning hole, and a handle is fixedly installed on the outer edge of the support sleeve.

[0018] Through the above technical solution, the positioning bolt passes through the first positioning hole and the second positioning hole to form a mechanical lock, bear the vertical load of the outrigger, and prevent the support column from sliding down unexpectedly. At the same time, the handle allows manual adjustment of the height or angle of the support sleeve during training, improving the ease of operation.

[0019] Compared with the prior art, the outrigger assembly for live-fire simulation training of aerial platform fire trucks provided by this utility model has the following beneficial effects:

[0020] 1. In this leg assembly scheme, the connection angle between the first telescopic cylinder and the first mounting base can be adjusted by the first adjusting bolt to compensate for the tilt angle deviation between the fire truck body and the ground, ensuring that the outrigger can be vertically supported even on non-horizontal ground. The rotational connection between the output end of the first telescopic cylinder and the mounting sleeve allows the support sleeve to automatically adjust its posture according to the terrain, avoiding stress concentration in the outrigger caused by rigid connection, and improving the adaptability of the outrigger to complex terrain in simulated training.

[0021] 2. In this leg assembly solution, the height of the support column relative to the ground can be manually adjusted, allowing the support column to slide within the support sleeve. Subsequently, the corresponding design of the first and second positioning holes allows the height of the support column to be fixed by inserting positioning bolts, preventing height drift caused by vibration and ensuring the positional stability of the leg during training.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figure 1-6 As shown, this example illustrates the configuration of the outrigger assembly for live-fire simulation training of a fire truck with an aerial platform.

[0031] based on Figure 1 As shown in the example, the outrigger assembly for the aerial platform fire truck's practical simulation training mainly consists of the fire truck body 1, the active boom 8, and the support sleeve 15.

[0032] The fire truck body 1 is fixedly installed with a connecting seat 2 at its outer edge. A connecting arm 3 is rotatably installed at the end of the connecting seat 2 away from the fire truck body 1. A first mounting seat 4 and an active arm 8 are fixedly installed at the end of the connecting arm 3 away from the fire truck body 1. A first telescopic cylinder 6 is rotatably installed at the end of the first mounting seat 4 away from the connecting arm 3. A second mounting seat 9 is fixedly installed at the end of the active arm 8 away from the connecting arm 3. A second telescopic cylinder 11 is provided at the end of the second mounting seat 9 away from the connecting arm 3. An installation sleeve 13 is provided at the output end of the first telescopic cylinder 6 and the second telescopic cylinder 11. A support sleeve 15 is fixedly installed at the end of the installation sleeve 13 away from the connecting seat 2. A support column 19 is slidably connected to the inner edge of the support sleeve 15.

[0033] Combination Figure 2 and Figure 3 As shown in the example, the first mounting base 4 and the first telescopic cylinder 6 are connected by a threaded first adjusting bolt 5, and the output end of the first telescopic cylinder 6 is rotatably mounted to the mounting sleeve 13.

[0034] Based on this configuration, the first adjusting bolt 5 can adjust the connection angle between the first telescopic cylinder 6 and the first mounting base 4, compensate for the tilt angle deviation between the fire truck body 1 and the ground, and ensure that the outriggers can be vertically supported even on non-horizontal ground. The rotational connection between the output end of the first telescopic cylinder 6 and the mounting sleeve 13 allows the support sleeve 15 to automatically adjust its posture according to the terrain, avoid stress concentration in the outriggers caused by rigid connection, and improve the adaptability of the outriggers to complex terrain in simulated training.

[0035] Further integration Figure 4 As shown, in this example, a third adjusting bolt 10 is threadedly connected between the second mounting base 9 and the second telescopic cylinder 11. A connecting block 12 is fixedly installed at the output end of the second telescopic cylinder 11. The connecting block 12 and the mounting sleeve 13 are rotatably installed. A second adjusting bolt 7 is provided between the connecting arm 3 and the active arm 8.

[0036] Based on this configuration, the second adjusting bolt 7 can adjust the angle between the active arm 8 and the connecting arm 3 to simulate different spans when the outriggers of a fire truck are deployed. The third adjusting bolt 10 is used to adjust the installation angle of the second telescopic cylinder 11, which works with the first telescopic cylinder 6 to achieve three-dimensional position adjustment of the outriggers. The rotating connection between the connecting block 12 and the mounting sleeve 13 allows the output end of the second telescopic cylinder 11 to swing synchronously with the support sleeve 15.

[0037] Combination Figures 2 to 5 As shown, in this example, an adjusting rod 14 is provided at the connection between the active arm 8 and the mounting sleeve 13, and an adjusting seat 22 is rotatably installed at the end of the support column 19 away from the support sleeve 15.

[0038] Based on this setup, the adjusting rod 14 can finely adjust the relative position of the mounting sleeve 13 and the active arm 8 to compensate for the cumulative error when the multi-section arm is deployed, ensuring that the support column 19 is placed vertically on the ground. The rotating installation of the adjusting seat 22 and the support column 19 allows the support plate 24 to adapt to the ground slope within a certain range, simulating the outrigger support state of a fire truck on complex terrains such as slopes and steps, thus improving the realism of the training scenario.

[0039] Further integration Figure 5 and Figure 6 As shown, in this example, a rotating rod 23 is provided at the connection between the adjusting seat 22 and the support column 19, and a support plate 24 is fixedly installed at the end of the adjusting seat 22 away from the support column 19.

[0040] Based on this configuration, the rotating rod 23 allows the adjusting seat 22 to rotate around the axis of the support column 19. When the support plate 24 contacts the irregular ground, it can automatically adjust its posture to increase the contact area and prevent the outriggers from slipping.

[0041] Combination Figure 2 and Figure 3As shown, in this example, a groove 16 is further provided on the inner edge of the support sleeve 15, a first positioning hole 17 is provided through the outer edge of the support sleeve 15, and a second positioning hole 20 is provided through the outer edge of the support column 19. The first positioning hole 17 and the second positioning hole 20 are in one-to-one correspondence.

[0042] Based on this setup, the height of the support column relative to the ground can be manually adjusted, allowing the support column 19 to slide within the support sleeve 15. Subsequently, the corresponding design of the first positioning hole 17 and the second positioning hole 20 allows the height of the support column 19 to be fixed by inserting the positioning bolt 21, preventing height drift caused by vibration and ensuring the positional stability of the outrigger during training.

[0043] Further integration Figure 5 As shown, in this example, a positioning bolt 21 is threaded between the first positioning hole 17 and the second positioning hole 20, and a handle 18 is fixedly installed on the outer edge of the support sleeve 15.

[0044] Based on this configuration, the positioning bolt 21 passes through the first positioning hole 17 and the second positioning hole 20 to form a mechanical lock, bear the vertical load of the outrigger, and prevent the support column 19 from slipping down unexpectedly. At the same time, the handle 18 allows manual adjustment of the height or angle of the support sleeve 15 during training, improving the ease of operation.

[0045] The following example illustrates the operation of the outrigger assembly used in the live-fire simulation training of the aerial platform fire truck.

[0046] Combination Figures 1 to 6 As shown, the outrigger assembly used for live-fire simulation training of aerial platform fire trucks adjusts the connection angle between the first telescopic cylinder 6 and the first mounting base 4 via the first adjusting bolt 5 to compensate for the tilt deviation between the fire truck body 1 and the ground, ensuring that the outriggers can provide vertical support even on non-horizontal ground. The rotatable connection between the output end of the first telescopic cylinder 6 and the mounting sleeve 13 allows the support sleeve 15 to automatically adjust its posture according to the terrain, avoiding stress concentration in the outriggers caused by rigid connections and improving the adaptability of the outriggers to complex terrain during simulation training. Furthermore, the angle between the active arm 8 and the connecting arm 3 is adjusted via the second adjusting bolt 7 to simulate different spans when the fire truck outriggers are deployed. The installation angle of the second telescopic cylinder 11 is adjusted via the third adjusting bolt 10, which, together with the first telescopic cylinder 6, enables three-dimensional position adjustment of the outriggers.

[0047] Based on the rotational connection between the connecting block 12 and the mounting sleeve 13, the output end of the second telescopic cylinder 11 can swing synchronously with the support sleeve 15. The adjusting rod 14 can finely adjust the relative position between the mounting sleeve 13 and the active arm 8 to compensate for the cumulative error when the multi-section arm is deployed, and ensure that the support column 19 lands vertically.

[0048] Based on the rotating installation of the adjusting seat 22 and the support column 19, the rotating shaft of the support plate 24 is allowed to adapt to the ground slope within a certain range, simulating the outrigger support state of a fire truck on complex terrains such as slopes and steps, thus improving the realism of the training scenario.

[0049] The adjusting seat 22 can be rotated around the axis of the support column 19 by rotating the rotating rod 23. When the support plate 24 contacts the irregular ground, it can automatically adjust its posture to increase the contact area and prevent the outrigger from slipping. The height of the support column from the ground can be manually adjusted so that the support column 19 can slide in the support sleeve 15. The corresponding design of the first positioning hole 17 and the second positioning hole 20 allows the height of the support column 19 to be fixed by inserting the positioning bolt 21 to prevent height drift caused by vibration and ensure the positional stability of the outrigger during training. The positioning bolt 21 passes through the first positioning hole 17 and the second positioning hole 20 to form a mechanical lock, bear the vertical load of the outrigger and prevent the support column 19 from slipping down unexpectedly. At the same time, the handle 18 can be used to manually adjust the height or angle of the support sleeve 15 during training to improve the ease of operation.
