Description

Technical Field

[0001] This disclosure relates to the field of engineering machinery, and in particular to a pipe-drafting vehicle and a suction rescue unit. Background Technology

[0002] Earthquakes, mudslides, and other geological disasters often result in people being buried alive. During rescue operations, the rescue area is large, the number of trapped people is high, and the burial depth is deep. Furthermore, the rescue window is short, and the environment is complex; the first 72 hours after the accident are the critical period for saving lives.

[0003] Currently, the efficiency of fire and rescue teams in clearing debris from above buried individuals is low, as the debris is difficult to remove quickly. Conventional machinery (excavators, loaders, bulldozers, etc.) used for close-range rescues poses a risk of secondary injury (collision, crushing, etc.) to the buried individuals due to the heavy loads involved, and is only suitable for the outer perimeter of the rescue area. Conventional manual clearing methods using hand tools or by hand are labor-intensive, inefficient, and prone to secondary collapses at accident sites, posing significant safety risks to rescue personnel.

[0004] To quickly and safely remove buried materials, specialized suction rescue equipment is required at accident sites to perform suction operations. Suction rescue equipment mainly comes in two types of drives: one is powered by a diesel or gasoline engine, and the other is electrically driven, which powers a hydraulic pump unit to provide power to the equipment. With the implementation of the "dual-carbon" policy, using diesel or gasoline engines not only pollutes the environment but also generates significant noise; therefore, electric drive systems have seen rapid development.

[0005] However, the electric drive technology of current suction rescue equipment still has shortcomings such as poor battery life, long charging time, and insufficient protection and detection, which affect rescue efficiency. Summary of the Invention

[0072] refer to Figures 1 to 4 Some embodiments of this disclosure provide a pipe-pulling vehicle for suction rescue, including a charging interface 3011, a power battery 302, a motor pump unit 303, and a power supply control unit 304.

[0073] Charging interface 3011 is configured to be electrically connected to an external power source to obtain electrical energy. Power battery 302 is optionally electrically connected to charging interface 3011. Motor pump assembly 303 is configured to provide hydraulic power and is optionally electrically connected to both charging interface 3011 and power battery 302. Power supply control unit 304 is communicatively connected to charging interface 3011 and power battery 302 and is configured to supply power to motor pump assembly 303 when charging interface 3011 is energized, and to determine whether charging interface 3011 charges power battery 302 based on the power battery's charge level.

[0074] Optionally, refer to Figure 2 and Figure 3 The pipe-hauling vehicle 3 includes a plug-in rectifier unit 301, which includes a charging interface 3011, a main switch 3012, and a rectifier module 3013. Optionally, the charging interface 3011 is compatible with a 220V AC power supply. Optionally, the power battery 302 is a lithium battery. The rectifier module 3013 is located in the circuit between the charging interface 3011 and the motor pump assembly 303, and is configured to convert the AC power provided by the charging interface 3011 into DC power, for example, converting AC 220V into DC 48V. The power supply control unit 304 includes a fuse assembly 3044 for preventing excessive current in the circuit. The fuse assembly 3044 and the main switch 3012 are sequentially located in the circuit at the power supply end of the motor pump assembly 303.

[0075] Optionally, the electric pump assembly 303 includes a DC motor 3031, a motor driver 3032, and a hydraulic pump assembly 3033. The motor driver 3032 is configured to drive the DC motor 3031 at a certain speed. The DC motor 3031 is connected to the hydraulic pump assembly 3033 and configured to drive the hydraulic pump assembly 3033, so that the hydraulic pump assembly 3033 provides the hydraulic power required for the pipe trailer 3 to travel and perform suction operations to the hydraulic system of the pipe trailer 3.

[0076] In the pipe-towing vehicle provided in the embodiments of this disclosure, when the charging interface 3011 is energized, that is, when the charging interface 3011 is electrically connected to the power source outside the pipe-towing vehicle 3, the charging interface 3011 can charge the power battery 302 according to the power battery 302 while supplying power to the motor pump unit 303. This not only saves the time of charging the power battery 302 separately, but also prevents the power battery 302 from frequently being in a state of low power, which is conducive to improving the range of the pipe-towing vehicle 3, extending the life of the power battery 302, meeting the requirements of continuous rescue, and improving rescue efficiency.

[0077] Some embodiments of this disclosure also provide a suction rescue unit, including a pipe-hauling trolley 3, a material trolley 2, a power vehicle 1, and a power generation system as provided in embodiments of this disclosure. The material trolley 2 is configured to collect the material suctioned by the pipe-hauling trolley 3. The power vehicle 1 is configured to provide suction power to the pipe-hauling trolley 3. The power generation system is detachably connected to a charging interface 3011 via a cable 5.

[0078] Optionally, refer to Figure 1 The power generation system can be located at the rear of the material car 2 and detachably connected to the charging interface 3011 via a cable 5 wound on a reel at one end. The power car 1 and the material car 2, and the material car 2 and the pipe-carrying car 3 are connected by a suction hose 4 to transmit suction power and transport materials.

[0079] The suction rescue equipment provided in the embodiments of this disclosure has the advantages of the pipe-drafting vehicle provided in the embodiments of this disclosure.

[0080] The control principle of the power supply control unit 304 of the pipe-hauling vehicle 3 in some embodiments of this disclosure will be further explained below.

[0081] In some embodiments, the power supply control unit 304 is configured to supply power from the power battery 302 to the motor pump assembly 303 when the charging interface 3011 is de-energized.

[0082] In the above embodiments, the power battery 302 can supply power to the motor pump group 303 when the charging interface 3011 is not connected to an external power source. If the power generation system of the suction rescue unit fails and cannot provide power, or if the power generation system is far away from the pipe trailer 3 and it is inconvenient to connect it through the cable 5, the power battery 302 can provide power to the pipe trailer 3. That is, the power battery 302 can be used as an emergency power source, which is conducive to meeting the timeliness requirements of rescue.

[0083] In some embodiments, the power supply control unit 304 is configured to disconnect the power between the power battery 302 and the motor pump assembly 303 when the charging interface 3011 is energized, so that the charging interface 3011 supplies power to the motor pump assembly 303 alone.

[0084] In the above embodiments, when the pipe-trailer 3 is powered by the charging interface 3011, the power battery 302 will not supply power to the motor pump group 303, thereby preventing the power battery 302 from charging and discharging at the same time, which protects the power battery 302 and helps to improve the stability and service life of the power battery 302.

[0085] In some embodiments, the power supply control unit 304 includes a normally open relay 3041 and a normally closed relay 3042. The normally open relay 3041 is disposed in the circuit between the charging interface 3011 and the motor pump assembly 303. When the charging interface 3011 is energized, the coil of the normally open relay 3041 is energized, connecting the charging interface 3011 to the motor pump assembly 303. The normally closed relay 3042 is disposed in the circuit between the power battery 302 and the motor pump assembly 303. When the charging interface 3011 is energized, the coil of the normally closed relay 3042 is energized, disconnecting the power battery 302 from the motor pump assembly 303.

[0086] refer to Figure 3 In the above embodiments, when the charging interface 3011 is energized, the coils of both the normally open relay 3041 and the normally closed relay 3042 are energized. The normally open contact of the normally open relay 3041 switches to the closed state, connecting the charging interface 3011 to the motor pump group 303. The normally closed contact of the normally closed relay 3042 switches to the open state, disconnecting the power battery 302 from the motor pump group 303. When the charging interface 3011 is de-energized, the coils of both the normally open relay 3041 and the normally closed relay 3042 are de-energized. The normally open contact of the normally open relay 3041 returns to and remains open, disconnecting the charging interface 3011 from the motor pump group 303. The normally closed contact of the normally closed relay 3042 returns to and remains closed, connecting the power battery 302 to the motor pump group 303.

[0087] Therefore, by setting normally open relay 3041 and normally closed relay 3042, interlocking can be achieved between the charging interface 3011 supplying power to the motor pump group 303 and the power battery 302 supplying power to the motor pump group 303, thereby preventing the power battery 302 from charging and discharging at the same time.

[0088] In some embodiments, the power supply control unit 304 includes a diode 3043, which is disposed in the circuit between the power battery 302 and the normally closed relay 3042 and is unidirectionally connected from the power battery 302 to the motor pump group 303.

[0089] In the above embodiment, when the charging interface 3011 is energized, the diode 3043 can prevent the normally closed relay 3042 from malfunctioning and causing reverse voltage to be applied to the power battery 302 or reverse current to flow to the power battery 302. Therefore, it can protect the power battery 302, thus forming a dual protection mechanism with the normally closed relay 3042.

[0090] In some embodiments, the power supply control unit 304 is configured to: if the charging interface 3011 is switched to the powered state and the power battery 302 has a charge level less than a first preset charge level, charge the charging interface 3011 to the power battery 302 until the power battery 302 is fully charged; if the charging interface 3011 is switched to the powered state and the power battery 302 has a charge level greater than a second preset charge level, disconnect the power supply between the charging interface 3011 and the power battery 302, wherein the second preset charge level is greater than the first preset charge level.

[0091] Optionally, the pipe-hauling vehicle 3 also includes a charging module 312, which is located in the circuit between the charging interface 3011 and the power battery 302 and can control whether the charging interface 3011 charges the power battery 302. The power supply control unit 304 includes an adapter socket 3045, which is located in the circuit between the charging interface 3011 and the power battery 302. The power battery 302 is communicatively connected to the charging module 312. If the power battery 302's charge level is less than a first preset charge level, the power battery 302 sends a charging request to the charging module 312, and the charging interface 3011 is connected to the power battery 302 until the power battery 302 is fully charged. Then, the power battery 302 sends a power-off request to the charging module 312, and the charging interface 3011 is disconnected from the power battery 302. If the power battery 302's charge level is greater than a second preset charge level, the power battery 302 does not send a charging request.

[0092] In the above embodiments, the power supply control unit 304 can prevent the power battery 302 from being charged frequently, which helps to improve the stability and service life of the power battery 302.

[0093] In the process of realizing this disclosure, the inventors discovered that during the suction rescue process, there are insufficient protective measures for the safety risks posed by the surrounding environment of the pipe-hauling vehicle and the pipe-hauling vehicle itself, and it is difficult to communicate with the rescued personnel in a timely and effective manner, which is not conducive to timely adjustment of the rescue plan.

[0094] To address the aforementioned issues, in some embodiments, the pipe-hauling vehicle 3 includes an action control unit 307 and a detection unit 305. The detection unit 305 is configured to detect the operating status of the pipe-hauling vehicle 3 and includes at least one of a tilt sensor 3051, a gas sensor 3052, a wading sensor 3053, and a temperature sensor 3054.

[0095] The following is combined with Figure 2 and Figure 4 The motion control unit 307, the detection unit 305, and the corresponding actuators will be further described.

[0096] In some embodiments, the pipe-hauling truck 3 includes a tilt sensor 3051, an alarm unit 306, and a motion control unit 307. The tilt sensor 3051 is configured to detect the tilt angle of the pipe-hauling truck 3 relative to a horizontal plane, the tilt angle including at least one of a pitch angle and a roll angle. The alarm unit 306 is capable of issuing an alarm signal. The motion control unit 307 is communicatively connected to the tilt sensor 3051 and the alarm unit 306 and is configured to cause the alarm unit 306 to issue an alarm signal if the pitch angle is greater than a first preset angle value or the roll angle is greater than a second preset angle value.

[0097] Considering the different weight distribution of the pipe-hauling truck 3 in different directions, the first preset angle value and the second preset angle value can be set to be the same or different. Optionally, the alarm unit 306 includes at least one of a buzzer 3061 and an audible and visual alarm 3062 to provide an audible alarm signal or an audible and visual alarm signal. Optionally, the suction rescue unit includes a display, which is communicatively connected to the motion control unit 307. The motion control unit 307 is configured to cause the display to show alarm prompt information, such as numerical information of the tilt angle and image and text information about the tilt of the entire machine, when the alarm unit 306 issues an alarm signal.

[0098] In the above embodiments, the tilt sensor 3051 can detect the overall attitude of the pipe trailer 3 in real time when the pipe trailer 3 is performing suction operation. The alarm unit 306 can issue an alarm signal when at least one of the pitch angle and roll angle exceeds the safe range, reminding the operator that the overall attitude of the machine is tilted and that there is a risk of tipping over. The operator can adjust the overall attitude of the machine in time or stop the pipe trailer from performing suction operation, which helps to enhance the safety protection of the pipe trailer 3.

[0099] In some embodiments, the pipe towing truck 3 includes a tilt sensor 3051, a control valve assembly 308, and a motion control unit 307. The tilt sensor 3051 is configured to detect the tilt angle of the pipe towing truck 3 relative to a horizontal plane, the tilt angle including at least one of a pitch angle and a roll angle. The control valve assembly 308 is disposed in the hydraulic system of the pipe towing truck 3 and includes at least one of a boom slewing control valve 3081 and a boom luffing control valve 3082. The boom slewing control valve 3081 is configured to control the slewing motion of the boom of the pipe towing truck 3, and the boom luffing control valve 3082 is configured to control the luffing motion of the boom of the pipe towing truck 3. The motion control unit 307 is communicatively connected to the tilt sensor 3051 and the control valve group 308 and is configured to: de-energize the boom slewing control valve 3081 so that the boom cannot perform slewing action if the roll angle is greater than a third preset angle value, and / or de-energize the boom luffing control valve 3082 so that the boom cannot perform luffing action if the pitch angle is greater than a fourth preset angle value.

[0100] Considering the difference in the overall weight distribution of the pipe-hauling truck 3 in different directions, the third preset angle value and the fourth preset angle value can be set to be the same or different.

[0101] In the above embodiments, the tilt sensor 3051 can detect the overall attitude of the pipe trailer 3 in real time when the pipe trailer 3 is performing suction operation, the boom slewing control valve 3081 can prevent the boom from performing slewing action when the roll angle exceeds the safe range, and the boom luffing control valve 3082 can prevent the boom from performing luffing action when the pitch angle exceeds the safe range. This can prevent the boom attitude adjustment when the vehicle body tilts severely, which would exceed the overall stability limit and cause the whole machine to overturn, thus enhancing the safety protection of the pipe trailer 3.

[0102] In some embodiments, the pipe-hauling truck 3 includes a gas sensor 3052, an alarm unit 306, and a motion control unit 307. The gas sensor 3052 is configured to detect the concentration of hazardous gas in the environment where the pipe-hauling truck 3 is located. The alarm unit 306 is capable of issuing an alarm signal. The motion control unit 307 is communicatively connected to the gas sensor 3052 and the alarm unit 306 and is configured to cause the alarm unit 306 to issue an alarm signal if the concentration is greater than a preset concentration value.
