Description

Technical Field

[0001] This application relates to the field of fire protection technology, and in particular to a fire rescue device and a fire rescue method. Background Technology

[0002] Disasters such as mudslides, typhoons, fires, and earthquakes require corresponding rescue vehicles or tools for rescue or firefighting. Firefighting and rescue equipment plays an important role in these disaster relief efforts. Existing firefighting and rescue equipment typically has functions such as elevated spray fire extinguishing, hydraulic breakers, hydraulic shears, grabbers (wood grabbers), shovels, and winches. However, when fighting fires in urban complexes, the exterior facades of these buildings are typically enclosed and solid concrete walls. Existing firefighting and rescue equipment is inefficient and time-consuming when breaking down these solid walls, making rapid rescue impossible. Furthermore, the large size of fire hoses can interfere with the demolition tools on the firefighting and rescue equipment, making it impossible to simultaneously demolish and spray fire hoses. As a result, smoke and dust can easily spread during the wall demolition process. Summary of the Invention

[0003] The main purpose of this application is to provide a fire rescue device and method that can quickly break through solid walls, achieve rapid rescue, and suppress dust.

[0004] To achieve the above objectives, this application adopts the following technical solution: According to one aspect of this application, a fire rescue device includes a main body, a drilling machine, and a spraying device. The drilling machine is disposed on the main body and includes: a frame, a drill bit, a rotary drive mechanism, and a feed mechanism. The drill bit is disposed on the frame; the rotary drive mechanism is disposed on the frame and connects to and drives the drill bit to rotate; the feed mechanism is disposed on the frame and is used to drive the drill bit to feed; wherein the rotary drive mechanism is a hydraulic drive mechanism. The spraying device is disposed on the main body and is capable of providing coolant to the drilling machine and spraying liquid to suppress dust during drilling.

[0005] According to one embodiment of this application, the drill bit has a tensile strength greater than or equal to 1400 MPa and a hardness greater than or equal to 40 HRC. The diameter of the drill bit is greater than or equal to 200 mm.

[0013] This application also provides a fire rescue method using the above-mentioned fire rescue equipment, wherein the fire rescue equipment includes a first detector and a second detector. The first detector is disposed on the drilling machine and is used to detect whether the axis of the drill bit is perpendicular to the drilled surface of the wall. The second detector is used to detect the smoke and dust concentration of the sprinkler device. The fire rescue method includes the following steps: Step S1: The first detector detects whether the axis of the drill bit is perpendicular to the surface of the wall to be drilled. If so, the drill bit is started to perform drilling operations; if not, the axis of the drill bit is readjusted until it is perpendicular to the surface of the wall to be drilled. Step S2: The drilling machine drills holes, and at the same time, the second detector detects the dust concentration around the spray device. When the dust concentration exceeds the threshold, the second detector sends a signal to the controller, and the controller controls the automatic start of the spray device to suppress dust.

Detailed Implementation

[0023] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this application will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0024] In the following description of various exemplary embodiments of this application, reference is made to the accompanying drawings, which form part of this application, and which illustrate by way of example different exemplary structures, systems, and steps that can implement various aspects of this application. It should be understood that other specific solutions to components, structures, exemplary devices, systems, and steps may be used, and structural and functional modifications may be made without departing from the scope of this application. Furthermore, while the terms “above,” “between,” “within,” etc., may be used in this specification to describe different exemplary features and elements of this application, these terms are used herein only for convenience, such as the orientation according to the examples described in the accompanying drawings. Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of this application.

[0025] It is understood that the terms "comprising" and "having," and any variations thereof, in the embodiments of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or components inherent to these processes, methods, products, or devices.

[0026] As used herein, “about,” “approximately,” “essentially,” or “substantially” includes the value and the average value within an acceptable range of deviations from a particular value as determined by one of ordinary skill in the art, taking into account the measurement under discussion and a particular number of errors associated with the measurement (i.e., limitations of the measurement system). For example, “about” may mean within one or more standard deviations of the value, or, for example, within ±30%, ±20%, ±15%, ±10%, ±5%. Furthermore, the use of “about,” “approximately,” “essentially,” or “substantially” herein may be chosen to select a more acceptable range of deviations or standard deviations depending on the nature of the measurement, the cutting nature, or other properties, and may not require a single standard deviation to apply to all properties.

[0027] Furthermore, relative terms such as “down” or “bottom” and “up” or “top” may be used herein to describe the relationship between one element and another, as illustrated in the figures. It should be understood that relative terms are intended to include different orientations of the device beyond those shown in the figures. For example, if a device in one figure is flipped, an element described as being “down” to another element will be oriented “up” to that element. Thus, the exemplary term “down” can include both “down” and “up” orientations, depending on the specific orientation of the figure. Similarly, if a device in one figure is flipped, an element described as being “below” or “under” another element will be oriented “above” that element. Thus, the exemplary terms “above” or “below” can include both “up” and “down” orientations.

[0028] This document describes exemplary embodiments with reference to cross-sectional views, which are schematic diagrams of idealized embodiments. Therefore, variations in the shape of the illustrations can be expected as a result of, for example, manufacturing techniques and / or tolerances. Consequently, the embodiments described herein should not be construed as limited to the specific shapes of the regions shown herein, but rather include, for example, shape deviations caused by manufacturing processes. For example, regions shown or described as flat may generally have rough and / or non-linear characteristics. Furthermore, the acute angles shown may be rounded. Therefore, the regions shown in the figures are schematic in nature, and their shapes are not intended to show the precise shapes of the regions, nor are they intended to limit the scope of this application.

[0029] See Figures 1 to 2The fire rescue equipment 1 of this application can be a fire truck, or other fire rescue equipment 1, such as a fire robot, a tracked fire rescue equipment 1, etc. To explain the fire rescue equipment 1 of this application in detail, the description uses a fire truck as an example. The fire rescue equipment 1 of this application includes a main body 10, a drilling machine 20, and a sprinkler device 60. In this embodiment, the main body 10 can be a vehicle body. The drilling machine 20 is disposed on the main body 10 and can drill holes in concrete walls. The drilling machine 20 includes: a frame 201, a drill bit 202, a rotary drive mechanism 203, and a feed mechanism 204. The drill bit 202 is disposed on the frame 201 and is used to drill holes in concrete walls; the rotary drive mechanism 203 is disposed on the frame 201 and connects to and drives the drill bit 202 to rotate; the feed mechanism 204 is disposed on the frame 201 and is used to drive the drill bit 202 to feed; wherein the rotary drive mechanism 203 is a hydraulic drive mechanism. The hydraulic drive mechanism can be a hydraulic motor. The spraying device 60 is installed on the main body 10. It can provide coolant to the drilling machine 20 and spray liquid on the wall to suppress dust when the drilling machine 20 is drilling holes in the concrete wall.

[0030] The fire rescue equipment 1 of this application is equipped with a drilling machine 20, which can drill through walls for rescue operations. The drilling machine 20 uses a hydraulic drive mechanism to drive the drill bit 202, which can provide the drill bit 202 with powerful wall-breaking force, and can penetrate solid concrete walls within one minute, greatly improving rescue efficiency. The fire rescue equipment 1 of this application has a sprinkler device 60 independent of the fire monitor of the fire rescue equipment 1, which can spray while breaking through obstacles, suppressing the spread of smoke and dust, which may include dust, smoke, and other solid particles or droplets suspended in the air. The sprinkler device 60 can provide coolant to the drilling machine 20, which simplifies the overall structure of the fire truck, making the fire truck's operation more efficient without complicating its structure.

[0031] The fire truck is also equipped with a log grabber 30, hydraulic shears 40, a hydraulic breaker, a breaker shovel, and a winch, which enable the fire truck to adapt to complex fire rescue situations and efficiently break through and rescue.

[0032] In this embodiment, the fire truck also includes a boom 50, which is foldable and retractable, enabling it to perform operations such as aerial spraying for fire extinguishing and demolition. See also Figures 3 to 4One end of the frame 201 of the drilling machine 20 is equipped with a conversion connector 211, which is used to connect to the boom 50 of the fire rescue equipment 1. This allows the drilling machine 20 to be connected to the boom 50, and under the influence of the boom 50, it can be lifted to a higher position for drilling. The drilling machine 20 can quickly drill through solid walls, improving rescue efficiency and greatly reducing loss of life and property. In addition, other demolition and rescue devices on the fire truck, such as the log grabber 30, hydraulic shears 40, hydraulic breaker, breaker shovel, and winch, are all equipped with connectors for connection to the boom 50, allowing personnel to select appropriate demolition devices according to the actual rescue situation.

[0033] In this specification, the drilling object of the drilling machine 20 is described using a wall as an example. However, the drilling machine 20 of this application can also drill holes in solid objects such as solid ground and floors.

[0034] In this embodiment, the main body 10 of the fire truck is also equipped with a water system for fire extinguishing, see [link / reference]. Figure 1 and Figure 6 The fire truck's sprinkler system 60 includes an atomizing nozzle 601 and a spray medium storage tank 602, both of which are located on the main body 10. The sprinkler system 60 is equipped with a dedicated spray medium storage tank 602, separating it from the fire-fighting water system. This allows for simultaneous demolition operations and spraying, and also enables the selection of different spray media based on various fire rescue situations, adapting to complex and diverse firefighting scenarios and expanding the fire truck's operational capabilities. In this embodiment, the spray medium can be water.

[0035] In this embodiment, the drill bit 202 of the drilling machine 20 has a tensile strength greater than or equal to 1400 MPa and a hardness greater than or equal to 40 HRC. Such a drill bit 202 is suitable for drilling into solid walls. The drill bit 202 can be made of tungsten alloy. The diameter of the drill bit 202 is greater than or equal to 200 mm, for example, 210 mm, 220 mm, 245 mm, etc. The length of the drill bit 202 is approximately 500 mm, ensuring that the hole formed by the drill bit 202 penetrates the wall to meet the requirements of a fire monitor, allowing the fire monitor to directly penetrate the wall through the hole drilled by the drilling machine 20 for fire extinguishing. The drill bit 202 has a cylindrical structure. One end of the drill bit 202 is connected to the rotary drive mechanism 203 via a round tube, and the other end is equipped with cutting edges spaced at intervals along the circumferential edge of the cylindrical structure. When the drilling machine 20 drills into the wall, the interior of the cylindrical structure of the drill bit 202 can accommodate the removed wall material.

[0036] In this embodiment, the feed mechanism 204 of the drilling machine 20 includes a telescopic cylinder and a slider assembly 2041. The telescopic cylinder is mounted on the frame 201, and the slider assembly 2041 can slide on the frame 201. The slider assembly 2041 is connected to the drill bit 202 via a square tube, which can drive the drill bit 202 to feed. The feed stroke of the feed mechanism 204 is approximately 500 mm, which is sufficient to drill through a solid wall. The slider assembly 2041 includes a slider that can slide on the frame 201 and a slider pressure plate connected to the telescopic cylinder. The slider pressure plate is fixed to the slider. A guide rail is provided on the frame 201 for the slider to slide on.

[0037] The drilling machine 20 of this application has a tungsten alloy drill bit 202 driven by a hydraulic rotary drive mechanism 203. The drill bit 202 rotates at a high speed during drilling, and the drill bit 202 is driven by the feed mechanism 204 to quickly drill holes in solid walls. Drilling can be completed within one minute, which saves valuable time for rescue, greatly improves rescue efficiency, and prevents the fire from spreading.

[0038] In this embodiment, see Figure 2 , Figure 3 and Figure 5 The frame 201 defines a receiving space 205, in which the drill bit 202 and the rotary drive mechanism 203 are disposed. The drill bit 202 can extend or retract into the receiving space 205. The feed mechanism 204 is located outside the receiving space 205 and can drive the drill bit 202 to extend or retract into the receiving space 205. The frame 201 is a welded structure, which can be composed of multiple hollow steel pipes welded into a hollow cube, and steel plates can be installed on the outer wall as needed. This protects the drill bit 202 and the rotary drive mechanism 203 of the drilling machine 20. By placing the feed mechanism 204 outside the receiving space 205, the volume and weight of the drilling machine 20 can be reduced, and the lifting height of the drilling machine 20 by the fire truck boom 50 can be increased, thus extending the lifting time.

[0039] In this embodiment, the frame 201 includes an end face 2011, and the space within the end face 2011 is an accommodating space 205. A first detector 2012 is provided on the end face 2011 to detect whether the end face 2011 is parallel to the surface of the concrete wall to be drilled. In practice, parallelism can be approximately parallel. Since fire trucks are usually a certain distance from the surface of the wall to be drilled from the ground, that is, fire trucks usually stay at a certain ground distance from the building, such as on the street, to extinguish fires in buildings, while the boom extends from the fire truck toward the building in the space above the ground, this causes an acute angle to be generated between the boom 50 and the surface of the wall to be drilled in the vertical plane. This can easily cause the axis of the drill bit 202 of the drilling machine 20 to be non-perpendicular to the wall surface, which is not conducive to quickly drilling through the solid wall. The drill bit 202 rotates around its own axis, which refers to the axis of rotation of the drill bit 202. Furthermore, the drilling position of the drilling machine 20 is too high for workers to reach, making it impossible to detect whether the axis of the drill bit 202 is perpendicular to the wall. Therefore, a first detector 2012 is installed at the end face 2011 of the frame 201. Workers can send a signal based on the detector's reading to start the drilling machine 20. The first detector 2012 can be a sensor, such as a laser rangefinder, or an inductor, such as a photoelectric sensor, etc.

[0040] In this embodiment, the drilling machine 20 includes a coolant inlet 206, which is connected to the spray device 60 and used to deliver coolant from the spray device 60 to the drill bit 202. The spray device 60 can provide coolant to the drill bit 202, thus simplifying the overall structure of the fire truck. Furthermore, the spray device 60 is equipped with a dedicated spray medium storage tank 602, separating the spray device 60 from the fire-fighting water system. This ensures that the coolant provided by the spray device 60 does not affect the fire-fighting water system, further enhancing the function of the spray device 60, improving the overall coordination of the various devices on the fire truck, and ultimately improving the performance of the fire truck.

[0041] In this embodiment, the main body 10 is also equipped with a hydraulic power source, which can provide the necessary power to various devices on the fire truck. The drilling machine 20 also includes a power source connector 207, a rotary drive mechanism interface 208, a feed mechanism interface 209, and a pressure relief interface 210. The rotary drive mechanism interface 208 is used to provide power to the rotary mechanism, the feed mechanism interface 209 is used to provide power to the feed mechanism 204, and the pressure relief interface 210 is used for pressure relief. The hydraulic power source is connected to the rotary drive mechanism interface 208, the feed mechanism interface 209, and the pressure relief interface 210 through the power source connector 207. In this way, the power of the drilling machine 20 can be obtained from the hydraulic power source, eliminating the need for a separate power source and simplifying the structure of the fire truck. The power source connector 207 enables the power source of each mechanism of the drilling machine 20 to be supplied by the power source connector 207, which simplifies the replacement operation. When the drilling machine 20 needs to be replaced, the power source connector 207 can be directly disconnected from the hydraulic power source. In addition, the power source connector 207 can be used as a dividing line for segmented maintenance, which can reduce maintenance costs.

[0042] In this embodiment, the spray device 60 further includes a second detector for detecting the concentration of smoke and dust around the spray device 60. The smoke and dust may include dust, smoke, and other solid particulate matter or droplets suspended in the air. When the smoke and dust concentration exceeds a threshold, the second detector sends a signal to the controller, which then controls the automatic start-up of the spray device 60. The second detector enables the automatic start-up of the spray device 60, avoiding manual intervention. The second detector can be a sensor, including aerosol sensors such as dust sensors and smoke sensors.

[0043] The fire truck of this application is also equipped with a controller, which can receive information detected by the first detector 2012 and the second detector to control various devices on the fire truck. The controller can be a conventional controller in the art, such as a PLC controller. The fire truck is also equipped with conventional components such as an operating panel and an alarm, which will not be described in detail here.

[0044] The fire rescue equipment 1 of this application also has a second embodiment, which is related to the fire rescue equipment 1 of the second embodiment. Figures 1 to 6 Compared to the fire rescue equipment 1 of the second embodiment, it has a substantially similar structure in its basic construction.

Therefore, in the following description of this embodiment, the structure is mainly the same as that of the fire rescue equipment 1 described in the embodiments. Figures 1 to 6The differences between the fire rescue equipment 1 and the embodiments described will be explained. In this second embodiment, the feed mechanism 204 of the drilling machine 20 can be a ball screw mechanism, with the ball replacing the slider assembly 2041 to connect to the drill bit 202. The rotation of the screw can drive the ball to move, thereby driving the drill bit 202 to move.

[0045] The fire rescue equipment 1 of this application also has a third embodiment, which is related to the fire rescue equipment 1 of the third embodiment. Figures 1 to 6 Compared to the fire rescue equipment 1 of the third embodiment, it has a substantially similar structure in its basic construction.

Figures 1 to 6 The differences between the fire rescue equipment 1 in the third embodiment will be explained. In this third embodiment, the feed mechanism 204 of the drilling machine 20 can be a synchronous belt mechanism, and the slider assembly 2041 is fixed at a certain position on the synchronous belt, so that the synchronous belt can drive the slider assembly 2041 to move, thereby driving the drill bit 202 to move.

[0046] The fire rescue equipment 1 of this application also has a fourth embodiment, which is related to the fire rescue equipment 1 of the fourth embodiment. Figures 1 to 6 Compared to the fire rescue equipment 1 of the previous embodiment, it has a substantially similar structure in its basic construction. Therefore, in the following description of the fire rescue equipment 1 of this fourth embodiment, the description will not be repeated.

Therefore, in the following description of this embodiment, the structure is mainly the same as that of the fire rescue equipment 1 described in the embodiments. Figures 1 to 6 The differences between the fire rescue equipment 1 in the embodiments will be explained. In this fourth embodiment, the feed mechanism 204 of the drilling machine 20 can be driven by a linear motor, which drives the slider assembly 2041, thereby moving the drill bit 202.

[0047] The above is a detailed description of several exemplary embodiments of the fire rescue equipment 1 proposed in this application. The following is a detailed description of the usage process of the fire rescue equipment 1 proposed in this application.

[0048] like Figures 1 to 6When drilling is required in a solid wall, the boom 50 of the fire truck raises the drilling machine 20 to an appropriate height via the adapter 211 of the drilling machine 20. The controller controls the first detector 2012 to detect whether the end face 2011 of the drilling machine 20 is parallel to the wall surface to be drilled. If it is not parallel, the operator is notified to make adjustments. After the first detector 2012 detects that the end face 2011 of the drilling machine 20 is parallel to the wall surface to be drilled, the controller sends a drilling signal status prompt. The operator presses the drilling start button, and the rotary drive mechanism 203 of the drilling machine 20 starts first, driving the drill bit 202 to rotate. Then the feed mechanism 204 drives the drill bit 202 to feed, and the drill bit 202 drills a hole in the wall. After drilling is completed, the feed mechanism 204 retracts the drill bit 202. The fire truck's fire monitor can pass through the hole drilled by the drilling machine 20 to extinguish the fire.

[0049] While the drilling machine 20 is drilling, the spraying device 60 delivers coolant through the coolant inlet 206 to cool the drill bit 202. At the same time, when the dust generated by drilling reaches a certain concentration, due to the scattering of dust, the second detector of the spraying device 60 can detect that the dust concentration has exceeded a preset threshold. The controller receives the information from the second detector and starts the atomizing nozzle 601 to spray and suppress dust.

[0050] Based on the above usage process of the fire rescue equipment 1 of this application, this application also provides a fire rescue method, which adopts the above fire rescue equipment 1, wherein the fire rescue equipment 1 includes a first detector 2012 and a second detector. The first detector 2012 is set on the drilling machine 20 and is used to detect whether the axis of the drill bit 202 is perpendicular to the drilled surface of the wall being drilled. In practice, perpendicularity means approximately perpendicularity. The second detector is used to detect the dust concentration of the sprinkler device 60. The fire rescue method includes the following steps: Step S1: The first detector 2012 detects whether the axis of the drill bit 202 is perpendicular to the drilled surface of the wall being drilled. If so, the drill bit 202 is started to perform drilling operations; if not, the axis of the drill bit 202 is readjusted until it is perpendicular to the drilled surface of the wall being drilled. Step S2: The drilling machine 20 drills holes, and at the same time, the second detector detects the dust concentration around the sprinkler device 60. When the dust concentration exceeds the threshold, the second detector sends a signal to the controller, and the controller controls the automatic start of the sprinkler device 60 to suppress dust.

[0051] The axis of the drill bit 202 can be readjusted by adjusting the angle of the connection between the adapter 211 and the boom 50, so that the axis of the drill bit 202 is perpendicular to the surface of the wall being drilled.

[0052] In summary, the fire rescue equipment proposed in this application includes a drilling machine, which can drill through walls for rescue operations with high efficiency. The drilling machine includes a frame, a drill bit, a rotary drive mechanism, and a feed mechanism. The drill bit is mounted on the frame and can be used to drill holes in concrete walls. The rotary drive mechanism is mounted on the frame, connecting to and driving the drill bit to rotate. The feed mechanism is mounted on the frame and used to feed the drill bit. The rotary drive mechanism is a hydraulic drive mechanism, and the drive mechanism for the drill bit is also hydraulic, providing the drill bit with powerful wall-breaking force. It can penetrate solid concrete walls within one minute, greatly improving rescue efficiency. The fire rescue equipment provided in this application also includes a sprinkler system, which is independent of the fire monitor of the fire rescue equipment. It can spray water while breaking through obstacles, suppressing the spread of smoke and dust while carrying out the rescue operation.
