Abstract

(57) [Summary] [Purpose] The objective is to obtain a work vehicle that can grasp the fuel required for traveling and prevent the situation where it is impossible to escape from a dangerous place. [Structure] It has a function of checking whether or not the amount of fuel is a prescribed amount via a fuel sensor. If the amount of fuel is equal to or greater than the prescribed amount, the amount is stored, and when the amount of fuel becomes 1/2 of the stored amount. This is a work vehicle safety device in which a controller having a function of outputting an alarm signal is connected to an alarm circuit.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This proposal relates to a work vehicle that travels on stairs, for example, to enter an underground mall and perform rescue work in the event of an accident such as a fire.

[0002]

[Prior art]

 Conventionally, there was a technology to move up and down stairs while keeping the driver's seat almost horizontal with respect to the forward and backward inclination of the aircraft.

[0003]

[Problems to be solved by the device]

 The above-mentioned work vehicles are capable of extinguishing fires and conducting rescue activities at a fire site, and can freely drive on slopes such as stairs.However, when going into a building or underground mall with such work vehicles If we do not know the amount of fuel in consideration, if we run out of fuel on the way, we may not be able to move to a safe place and may be fatal. Therefore, the purpose of this plan is to obtain a work vehicle that can grasp the fuel required for traveling and prevent the situation where it is impossible to escape from a dangerous place.

[0004]

[Means for Solving the Problems]

 This plan provides the following work vehicles in order to achieve the above objectives. In other words, it has a function to check whether the amount of fuel is the specified amount or not via the fuel sensor, and if it is more than the specified amount, the amount is stored and an alarm is issued when the fuel reaches the specified amount of the stored amount. This is a work vehicle safety device in which a controller that has the function of outputting signals is connected to an alarm circuit.

[0005]

[Action]

 Before starting fire extinguishing and rescue activities, the amount of fuel is checked and stored, and if it is below the specified amount, an alarm is issued, and if it is above the specified amount, the amount is stored and if the amount of fuel is the specified amount, 1 / When it reaches 2, an alarm is issued.

【Example】

 Embodiments shown in the drawings will be described below. First, the conventional rocking type working vehicle for a cabin will be described. In FIGS. 3 to 7, 1 is a work vehicle for traveling on inclined ground, 2 is a cabin in which a driver's seat 3 and a driving operation unit 4 are installed, 5 is left and right front crawlers 6, 7 and rear crawlers 8 for traveling. , A machine body supporting 9 and 10 is an engine room at a lower rear portion of the cabin 2, and an engine 12 and a water pump for extinguishing a fire are arranged in the engine room 10. Reference numeral 17 denotes a working machine installation stand that also serves as the engine room upper cover, and 18 denotes a fire hose device which is a working machine installed on the installation stand 17. The cabin 2 is supported on the machine base 5 so as to be swingable back and forth. The front end of the first cabin 22 is connected to the front end of the machine base 5 via a front fulcrum shaft 21. The rear end of the second cabin stand 24 is connected to the rear end via the rear fulcrum shaft 23, and the floor surface of the cabin 2 for the driver is fixed to the second cabin stand 24. A first lifting cylinder 28 for tilting the cabin forward is provided between the inner sides of the cabin base 22 via the respective support shafts 26 and 27, and the support shafts are provided between the outer sides and the center of the first and second cabins 22 and 24. A second lifting cylinder 31 for tilting the cabin rearward is provided via 29 and 30, and by extending and contracting the cylinders 28 and 31, the cabin 2 is tilted forward or backward around the front or rear fulcrums 21 and 23. It is configured to tilt.

Further, in FIG. 7, reference numeral 32 denotes an inclination sensor provided in a substantially central portion of the machine base 5 for detecting an inclination angle in the front-rear direction. Reference numeral 33 is a rear stroke sensor provided on the first lifting cylinder 28 for tilting the cabin 2 forward, 34 is a front stroke sensor provided on the second lifting cylinder 31 for tilting the cabin 2 backward, and 35 is a manual switch. These are connected to the controller 36. Reference numeral 37 is a solenoid valve for vertically moving the first lifting cylinder 28, and 38 is a solenoid valve for vertically moving the second lifting cylinder 31. Now, when the engine 12 is started and the aircraft is moved forward while climbing the inclined surface or the stairs, the inclination angle sensor 32 provided on the machine base 5 detects the angle and the first lifting cylinder 28 extends as shown in FIG. The first cabin base 22 is raised. The rear stroke sensor 33 provided in the first lifting cylinder 28 detects the horizontal state of the cabin 2 and stops the lifting. Further, as shown in FIG. 6, when descending downhill or downstairs from the horizontal road surface, the second elevating cylinder 31 for rearward tilting of the cabin is extended by the detection of the tilt sensor 32 and the second cabin base 24 and the cabin. Tilt 2 forward. Then, the front stroke sensor 34 provided in the second lifting cylinder 31 detects the horizontal state of the cabin 2 and stops the descent. 40 in FIG. 3 is a fuel tank.

[0008] By the way, when going into a building or an underground mall with a work vehicle as described above for extinguishing a fire or rescue work at a fire site, the amount of fuel must be grasped in consideration of the way back. If fuel runs out on the way, it may not be possible to move to a safe place, which may be life-threatening. Based on the above, this plan is to create a work vehicle that can grasp the fuel required for traveling on the way back home due to dangerous work such as fire extinguishing or rescue work, and prevent the situation where it is impossible to escape from a dangerous place. .

That is, a fuel sensor 41 is provided in the fuel tank 40 as shown in FIG. 1, and this is connected to an alarm circuit 43 via a controller 42. Reference numeral 44 shown in FIG. 1 denotes an alarm stop switch. The controller 42 has the following functions. That is, check the fuel amount before starting fire extinguishing and rescue activities, and memorize it, and keep it below the specified amount. For example, if it is 1/2 or less, an alarm is issued. When it becomes 1/2, it will start issuing an alarm. Specifically, as shown in FIG. 2, when the key switch 44 is turned ON 45 before the start of fire extinguishing and rescue operations, the fuel amount is first measured as indicated by 46 and is less than the specified amount as indicated by 47. Whether or not it is checked, and if it is below the specified amount, an alarm 50 is output. If the amount is equal to or more than the specified amount, the initial fuel is stored as an initial value as shown by 48, and if the current amount is less than the initial value 1/2 as shown by 49, an alarm 50 is output. Since this plan is structured as described above, the operator will be informed of the time to move to the return journey. A linear fuel sensor is used to detect the fuel amount. In any case, since the fuel amount is checked by the controller via the fuel sensor, the vehicle of the present invention can travel with peace of mind.

[0010]

[Effect of device]

 According to the plan, it is possible to grasp the fuel necessary for traveling on the return trip due to dangerous work in fire extinguishing and rescue operations, and prevent the situation where it becomes impossible to escape from a dangerous place.
