In this embodiment, the cab 12 is assembled on the front end of the front support section 10, and the front end of the front support section 10 is inclined downward compared to the rear end of the front support section 10, so that the bottom of the cab 12 is lowered compared to the rear end of the front support section 10, and the height of the cab 12 is reduced, so that the height of the top end of the cab 12 from the ground is not more than 2m.

In some embodiments, a front support section 10 is connected to the front end of the sink section 8. The rear support section 11 is connected to the rear end of the sinking section 8.

The sinking section 8 and the rear support section 11 are used for supporting the upper assembly 4, wherein the lifting platform 7 in the upper assembly 4 is assembled to the sinking section 8. Thus, the layout of the cab 12, the battery pack 6 and the upper assembly 4 assembled on the chassis girder 5 is reasonable and compact, the occupied space is reduced, and the whole miniaturization of the pipeline refueling truck 1 is promoted. The sinking section 8 is recessed downward so that an accommodation space 33 can be formed, and the accommodation space 33 is used for assembling the lifting platform 7, so that the height of the top end of the lifting platform 7 from the ground can be reduced, and the whole height of the pipeline refueling truck 1 is ensured to be lowered and not to exceed 2m. In some embodiments, the distance between the upper surfaces of the front support section 10 and the rear support section 11 and the upper surface of the sink section 8 is 190mm. In some embodiments, the height of the lifting platform 7 when not raised is 1580mm. In some embodiments, the front support section 10 is hollowed out. In some embodiments, the rear support section 11 is hollowed out. In some embodiments, the countersink 8 is hollowed out. The front support section 10, the rear support section 11 and the sinking section 8 are hollow, so that the manufacturing materials of the chassis girder 5 can be reduced, resources are saved, and the weight of the chassis girder 5 is reduced.

In some embodiments, the length of the chassis girder 5 ranges from 6000mm to 6100mm. In some embodiments, the sink element 8 has a width ranging from 750mm to 850mm. In some embodiments, the length of the front support section 10 ranges from 1500mm to 1600mm. In some embodiments, the length of the rear support section 11 ranges from 2100mm to 2200mm.

In some embodiments, the upper surface of the submerged section 8 is a horizontal plane, the front support section 10 comprises a front section plane 34 parallel to the upper surface of the submerged section 8, the rear support section 11 comprises a rear section plane 35 parallel to the upper surface of the submerged section 8, the front section plane 34 is level with the rear section plane 35 in the height direction, and the height difference between the upper surface of the submerged section 8 and the front section plane 34, the rear section plane 35 ranges from 180mm to 200mm. The upper surface of the sinking section 8 is in a horizontal state, and the lower surface of the lifting platform 7 is also in a horizontal state, so that the lifting platform 7 is assembled on the upper surface of the sinking section 8, the level of the mounting surface of the lifting platform 7 is ensured, and the mounting stability of the lifting platform 7 is improved. The front section plane 34 is level with the rear section plane 35, so that the stress generated by the transition connection of the sinking section 8 and the front support section 10 is the same as the stress generated by the transition connection of the sinking section 8 and the rear support section 11, and the load transmission of the chassis girder 5 is balanced, and the stability is improved.

In some embodiments, the chassis girder 5 includes a front connection section 36 connecting the sinking section 8 and the front support section 10, and a rear connection section 37 connecting the sinking section 8 and the rear support section 11, the lower end of the front connection section 36 being connected to the sinking section 8, the upper end being connected to the front support section 10, the lower end of the rear connection section 37 being connected to the sinking section 8, the upper end being connected to the rear support section 11, the upper end of the front connection section 36 being inclined with respect to a side facing away from the rear connection section 37 with respect to a vertical plane, and the upper end of the rear connection section 37 being inclined with respect to a side facing away from the front connection section 36 with respect to a vertical plane. The front connecting section 36 can realize the transition of the height difference between the front supporting section 10 and the sinking section 8, and the front connecting section 36 which is obliquely arranged is beneficial to the load transmission between the front supporting section 10 and the sinking section 8, so that the stress concentration at the front connecting section 36 is avoided. The rear connecting section 37 can realize the transition of the height difference between the sinking section 8 and the rear supporting section 11, and the rear connecting section 37 which is obliquely arranged is beneficial to the load transmission between the sinking section 8 and the rear supporting section 11, so that the stress concentration at the rear connecting section 37 is avoided. In one embodiment, in the horizontal plane, the width dimension of the front connecting section 36 is the same as the width of the sinking section 8 and the front supporting section 10 in the width direction (Y direction in fig. 5) perpendicular to the length direction of the vehicle body, and the front connecting section 36 is connected between the front end of the sinking section 8 and the front supporting section 10, so that the front end of the sinking section 8 and the front supporting section 10 are connected more firmly, and are not broken due to stress concentration caused by abrupt change of the section. The rear connecting section 37 is used for connecting the rear end of the sinking section 8 and the front supporting section 10, so that the rear end of the sinking section 8 is connected with the rear supporting section 11 more firmly, and the sinking section is not broken due to stress concentration caused by abrupt change of the section. The overall stability of the chassis frame 5 is improved by connecting the sinking section 8 and the front support section 10 via the front connecting section 36 and the sinking section 8 and the rear support section 11 via the rear connecting section 37. The front connecting section 36 is inclined towards the front support section 10 relative to the vertical direction, and the rear connecting section 37 is inclined towards the rear support section 11 relative to the vertical direction, so that the corresponding space of the upper surface of the sinking section 8 in the vertical direction is enlarged towards two sides, and the lifting platform 7 is assembled. And, when the upper assembly component 4 is assembled, the stress concentration in the sinking section 8 and the peripheral area thereof is avoided, which is beneficial to improving the stability of the chassis girder 5.

With continued reference to fig. 5, in some embodiments, the sinker section 8 includes a first sinker beam 38 and a second sinker beam 39 extending in the front-to-back direction (X-direction in fig. 5), the first sinker beam 38 being parallel to and spaced apart from the second sinker beam 39, and the sinker section 8 further includes a connecting beam 40 connecting the first sinker beam 38 and the second sinker beam 39. In this embodiment, the first sinking beam 38 and the second sinking beam 39 are connected between the front support section 10 and the rear support section 11 at intervals, and are used for supporting the lifting platform 7, so that the stress of the lifting platform 7 is balanced, and the stability of the lifting platform 7 is improved. The first sinking beam 38 and the second sinking beam 39 are arranged in parallel, so that the first sinking beam 38 and the second sinking beam 39 are positioned on the same horizontal plane, which is beneficial to balancing the load transmission of the chassis girder 5 and enables the chassis girder 5 after the assembly component 4 is assembled to be more stable. The upper surface of the connecting beam 40 is in direct contact with the lifting platform 7, and the first sinking beam 38 and the second sinking beam 39 connected to the two ends of the connecting beam 40 are used for supporting the gravity of the lifting platform 7 together with the connecting beam 40 and balancing the gravity of the lifting platform 7, so that the overall stability of the chassis girder 5 is improved.

In some embodiments, the front support section 10 includes a contiguous front support front section 41 and a front support rear section 42, the front support rear section 42 connecting the front support front section 41 with the sink section 8, the front end of the front support front section 41 being inclined downwardly. In this embodiment, the front support front section 41 corresponds to the support cab 12, and the front support rear section 42 corresponds to the support battery 6. The cab 12 is sized larger than the battery pack 6 and has a height larger than the battery pack 6, and the front support front section 41 is provided to be inclined downward as compared with the front support rear section 42, so that the height of the cab 12 correspondingly supported is lowered to ensure that the overall height of the pipeline tanker 1 is not more than 2m.

In some embodiments, the front support rear section 42 is provided as a variable cross-section beam. A larger cross section is used at a location where the bending moment is larger, and a smaller cross section is used at a location where the bending moment is smaller. Such beams with a variable cross-section along the axis are called variable cross-section beams. The bending moment of the front end of the front support rear section 42 is smaller, a smaller cross section is adopted, the bending moment of the rear end of the front support rear section 42 is larger, and a larger cross section is adopted, so that the manufacturing materials of the chassis girder 5 are reduced at the front end of the front support rear section 42, resources are saved, and the weight of the chassis girder 5 is reduced.

In some embodiments, the front support front section 41 is provided as a constant cross-section beam. The beam with the same cross-sectional dimension at any place along the length of the beam is an equal cross-sectional beam. Since the weight of the cab 12 is large and the front support front section 41 corresponds to the support cab 12, the front support front section 41 is provided as a constant cross-section beam to improve the bending strength of the front support front section 41, thereby making the assembly of the cab 12 to the front support front section 41 more stable. In one embodiment, the length of the front support front section 41 is less than the length of the front support rear section 42, and the cross section of the front support front section 41 is approximately equal to the cross section of the rear end of the front support rear section 42.

In some embodiments, the front support rear section 42 includes a first sub-section 43 and a second sub-section 44 connected, the first sub-section 43 being connected to the rear end of the front support front section 41, the second sub-section 44 being connected to the front end of the sink section 8, the cross section of the first sub-section 43 increasing from front to back. That is, the front support front section 41 and the sinking section 8 are connected by the first sub-section 43 and the second sub-section 44 in this order from front to back. Because the submerged section 8 is recessed from other portions of the chassis frame 5, stress concentrations are more likely to occur at the connection locations at the ends of the submerged section 8, and in order to reduce or avoid such stress concentrations, the present application provides the first sub-section 43 in the front support rear section 42 as a variable cross-section beam to increase the ability of the front end of the submerged section 8 to carry both lateral and vertical loads and reduce the risk of deformation or breakage of the connection of the submerged section 8. In addition, assembled at the first sub-section 43 is the battery pack 6 with larger mass, the cross section of the first sub-section 43 is gradually increased from front to back, so that the thickness of the first sub-section 43 is gradually increased from front to back, the bearable pressure is gradually increased, and the supporting effect on the battery pack 6 is better.

In some embodiments, the second sub-section 44 is provided as a constant cross-sectional beam, and the cross-sectional area of the second sub-section 44 is equal to the cross-sectional area of the large end of the first sub-section 43. In this way, the strength of the connection of the second sub-section 44 with the submerged section 8 can be increased, and since the second sub-section 44 is closer to the submerged section 8 than the first sub-section 43, the resistance of the second sub-section 44 to deformation and breakage can be increased. In addition, the rear part of the battery pack 6 is assembled to the second sub-section 44, and the second sub-section 44 is a constant cross-section beam, so that the upper surface of the second sub-section 44 is horizontal, and the bending strength of the second sub-section 44 is improved, thereby ensuring that the second sub-section 44 and the battery pack 6 are assembled more firmly.

In some embodiments, the rear support section 11 includes a contiguous rear support front section 45 and a rear support rear section 46, the rear support front section 45 connecting the rear support rear section 46 with the sink section 8, the rear support front section 45 having a cross section that is unequal to the cross section of the rear support rear section 46. In this embodiment, the rear end of the sinking section 8 is connected in turn to a rear support front section 45 and a rear support rear section 46, the rear support front section 45 and rear support rear section 46 being used to assemble the filter 28, recovery tank 32, reel 25 and filler tube assembly 3. The cross section of the rear support front section 45 gradually decreases from front to rear, that is, the bottom surface of the rear support front section 45 gradually slopes upward from front to rear. Because the stress at the sinking section 8 of the pipeline refueling truck 1 is concentrated, the weight on the chassis girder 5 is concentrated at the sinking section 8 and the vicinity of the sinking section 8, and therefore, the rear support front section 45 close to the sinking section 8 is arranged to be gradually inclined upwards, so that the whole vehicle weight is prevented from being concentrated at the sinking section 8 and the vicinity thereof, and the stability of the whole vehicle is improved. In some embodiments, the rear support front section 45 is inclined upwardly at an angle of 4 degrees relative to the bottom end of the sink section 8.

In some embodiments, the rear support front section 45 is provided as a variable cross-section beam, with the cross-section of the rear support front section 45 tapering from front to rear. The rear support front section 45 is a variable cross-section beam, whereby the rear support front section 45 can be increased in resistance to deformation and damage due to the rear support front section 45 being closer to the submerged section 8 than the rear support rear section 46. And, the rear end of back support anterior segment 45 is far away from sinking section 8, and the cross-section of the rear end of back support anterior segment 45 is less, can reduce the manufacturing material of chassis girder 5, saves the resource and lightens the weight of chassis girder 5 itself.

In some embodiments, the rear support rear section 46 is configured as a constant cross-sectional beam, and the cross-sectional area of the rear support rear section 46 is equal to the cross-sectional area of the large end of the rear support front section 45, thereby reducing the weight of the rear support rear section 46 if the rear support rear section 46 is loaded. That is, the upper surface of the rear support rear section 46 is horizontal, which increases the bending strength of the rear support rear section 46, thereby making the partial upper assembly 4 assembled on the rear support rear section 46 more stable.

In some embodiments, the submerged section 8 is located at 2/3 of the chassis frame 5, and the midpoint of the chassis frame 5 is located at the front of the midpoint of the submerged section 8. So set up, make the lift platform 7 of equipment in section 8 department of sinking set up near driver's cabin 12, need not to assemble at the tail end of back braced section 11, optimize whole car overall arrangement, and avoid partial lift platform 7 to be in unsettled state, cause the vehicle to throw the tail problem.

With continued reference to fig. 1 and 2, in some embodiments, the fuel line assembly 3 includes a ground connector 13 for connection to a ground plug and a fuel line 15 connected to the ground connector 13, the fuel line 15 extending from one side of the line truck 1 through the tail to the other side of the line truck 1. The well joint 13 is used for communicating the oil delivery pipe 15 with a well plug on the ground. The oil delivery pipe 15 surrounds the outer edge of the chassis girder 5, so that the length of the oil delivery pipe 15 is long enough, and the velocity of the aviation oil in the oil delivery pipe 15 is low, so that the impact of the aviation oil in the oil delivery pipe 15 on other oil filling pipe assemblies 3 communicated with the oil delivery pipe 15 is reduced. In some embodiments, the oil delivery tube 15 includes a first oil delivery tube 16, the first oil delivery tube 16 extending from one side of the pipeline tanker 1 through the tail to the other side of the pipeline tanker 1.

In some embodiments, the battery pack 6 is assembled between the cab 12 and the lift platform 7.

In some embodiments, the fuel line assembly 3 includes a ground well connection 13, a fuel connection 14, and a fuel line 15 connecting the ground well connection 13 and the fuel connection 14, the fuel connection 14 for connection with a fuel filler port of an aircraft, the ground well connection 13 removably connected to the chassis frame 5, and the fuel connection 14 removably connected to the lift platform 7. The fueling line assembly 3 is used to route the pilot oil from the ground well to the fueling port of the aircraft for fueling the aircraft by filtering through the filter 28 and metering by the flow meter. Specifically, the ground well is first connected to the ground via the ground well connector 13, and then the fueling personnel can connect the fueling connector 14 to the fueling port of the aircraft via the lifting platform 7, so that the transportation of the ground well aviation fuel is realized via the fueling pipeline assembly 3 of the pipeline fueling vehicle 1. When the pipeline refueling truck 1 does not refuel an aircraft, the ground well joint 13 is assembled on the chassis girder 5 and is close to the cab 12, so that the pipeline refueling truck 1 is prevented from falling easily when running; when the pipeline fuelling vehicle 1 fuelling an aircraft, the ground well connector 13 is taken off the chassis girder 5 and connected with the ground well, so that the ground well connector 13 is conveniently connected with the ground well on the ground.

The first oil delivery pipe 16 is a rubber pipe and is wound from one side of the lifting platform 7 to the other side of the lifting platform 7 through the tail of the vehicle. Compared with a metal hard tube, the rubber tube is convenient for the oiling personnel to change the moving track and lighten the work of the oiling personnel. And, the first oil pipe 16 is wound from one side of the lifting platform 7 to the other side of the lifting platform 7 through the vehicle tail.

A first stopper 60 is formed to protrude upward from the upper surface of the pallet 59. In some embodiments, the first blocking member 60 is vertically upward and forms a bent shape with the pallet 59 in a horizontal form, thereby forming an accommodating space, which is the oil delivery pipe accommodating space 51 capable of accommodating the oil delivery pipe 15. So, simple structure holds oil pipe 15 effectual. In some embodiments, the first blocking member 60 is hollow, so as to save manufacturing materials, reduce cost, and reduce the overall weight of the tray 50, and facilitate the movable member 55 to drive the tray 50 to lift.

Fig. 11 is a front view of the leaf spring assembly 73 of the pipeline truck 1 shown in fig. 1. Fig. 12 is a top view of the leaf spring assembly 73 of the pipeline truck 1 shown in fig. 11. As shown in connection with fig. 1,2, 11, 12, the pipeline truck 1 comprises a front axle (not shown), an electric chassis 2, and a leaf spring assembly 73. The electric chassis 2 comprises chassis girders 5. The leaf spring assembly 73 is supported at both ends to the chassis frame 5, and at its middle end to a front axle (not shown) and is supported below the chassis frame 5. The leaf spring assembly 73 is located between the bottom end of the chassis frame 5 and the upper end of the front axle (not shown). The leaf spring assembly 73 is an elastic element of the suspension system of the pipeline cart 1, and functions to cushion and attenuate the vehicle in the case of road surface bumps and road irregularities when the pipeline cart 1 is traveling, and to position and guide the pipeline cart 1 when it is traveling or turning.

Since the middle ends of the plurality of leaf spring blades 75 are supported at a front axle (not shown) and the front axle (not shown) is only one supporting point, the middle ends of the plurality of leaf spring blades 75 need to have a strong bending resistance. Therefore, the thickness of the plurality of leaf spring blades 75 is gradually increased from both ends to the middle end, and the rigidity of the middle end of the plurality of leaf spring blades 75 is enhanced, so that the bending resistance of the plurality of leaf spring blades 75 is enhanced, the plurality of leaf spring blades 75 are not easy to bend, and the cab 12 above the plurality of leaf spring blades is more stable and reliable.

Specifically, the inclined pad 82, the center pad 80, and the middle portions of the plurality of leaf spring blades 75 are provided with a plurality of through holes, respectively. The plurality of through holes form communication channels after the diagonal gasket 82, the center pad 80, and the plurality of leaf spring blades 75 are stacked.

When the electric energy is supplied to the upper driving motor 113, the upper driving motor 113 drives the upper assembly component 4 to operate, the walking motor 112 is powered off, noise pollution is not caused, energy is saved, emission is reduced, and considerable economic benefits are achieved. The whole vehicle controller 142 is a core control part of the whole pipeline refueling truck 1. The vehicle controller 142 may monitor the states of the plurality of components in the pipeline refueling truck 1, and control the all-in-one controller 143 according to the states of the plurality of components to distribute the electric power of the battery pack 6 to one of the travel motor 112 and the upper drive motor 113. Specifically, the vehicle controller 142 collects the driving signal of the driving wheel 9 and the running state signal of the upper assembly 4, and controls the all-in-one controller 143 to distribute the electric energy of the battery pack 6 to the running motor 112 according to the driving signal of the driving wheel 9 and the running state signal of the upper assembly 4, so that the driving wheel 9 can run; or controls the unified controller 143 to distribute the power of the battery pack 6 to the upper driving motor 113 so that the upper assembly 4 can be operated. In this way, the electric energy of the battery pack 6 can be optimally matched, and the vehicle state of the pipeline refueling truck 1 can be monitored, so that the stability and reliability of the pipeline refueling truck 1 are improved. In some embodiments, the pipeline truck circuit 153 includes a low voltage power supply 154 electrically connected to the vehicle controller 142 for powering the vehicle controller 142. In some embodiments, the low voltage power supply 154 is electrically connected to the battery pack 6 to convert the high voltage of the battery pack 6 to a low voltage to power the vehicle controller 142. In some embodiments, the pipeline truck circuit 153 includes a PLC controller 158 electrically connected between the low voltage power supply 154 and the vehicle controller 142, and the PLC controller 158 is configured to convert the collected signals from the various components on the pipeline truck 1 into codes and send the codes to the vehicle controller 142.

In some embodiments, the pipeline truck circuit 153 includes a travel motor controller 155 electrically connected to the travel motor 112 for controlling the operating state of the travel motor 112. The travel motor controller 155 is used to control the start or stop of the travel motor 112, and may also control the rotation speed of the travel motor 112.

The upper motor controller 156 is used to control the start or stop of the upper driving motor 133, and also to control the rotation speed of the upper driving motor 133.

In some embodiments, the pipeline truck circuit 153 includes a control switch 157, the control switch 157 being electrically connected to the vehicle controller 142; the whole vehicle controller 142 is configured to detect an open/close state of the control switch 157, and when the control switch 157 is in one of the closed and open states, control the all-in-one controller 143 to distribute the electric power of the battery pack 6 to the travel motor 112, and when the control switch 157 is in the other of the closed and open states, control the all-in-one controller 143 to distribute the electric power of the battery pack 6 to the upper drive motor 113. In this embodiment, the vehicle controller 142 controls the all-in-one controller 143 to distribute the electric power of the battery pack 6 to the travel motor 112 and/or the upper drive motor 113 by monitoring the state of the control switch 157. The operator can operate the control switch 157 to switch the state of the control switch. For example, the control switch 157 may be normally open, and when refueling is desired, the operator depresses the control switch 157, which closes the control switch 157. For example, when the control switch 157 is turned off, the whole vehicle controller 142 monitors a low level, indicating that the driver may need to drive the vehicle, and then controls the all-in-one controller 143 to distribute the electric power of the battery pack 6 to the travel motor 112, not to the upper drive motor 113, so that the travel motor 112 drives the drive wheels 9 to travel; when the control switch 157 is closed, the whole vehicle controller 142 monitors a high level, indicating that an operator may need to refuel the aircraft through the upper assembly 4, and then the all-in-one controller 143 is controlled to distribute the electric power of the battery pack 6 to the upper drive motor 113 and not to the travel motor 112, thereby allowing the upper assembly 4 to operate normally. Or when the control switch 157 is turned off, the whole vehicle controller 142 monitors a low level, which means that an operator may need to refuel the aircraft through the upper assembly 4, and then the all-in-one controller 143 is controlled to distribute the electric energy of the battery pack 6 to the upper assembly driving motor 113 and not to the traveling motor 112, so that the upper assembly 4 operates normally; when the control switch 157 is closed, the whole vehicle controller 142 monitors a high level, which indicates that the driver may need to drive the vehicle, and controls the all-in-one controller 143 to distribute the electric power of the battery pack 6 to the travel motor 112, not to the upper drive motor 113, so that the travel motor 112 drives the drive wheels 9 to travel. In this way, the vehicle controller 142 detects the state of the control switch 157, and controls the all-in-one controller 143 to distribute the electric energy of the battery pack 6 to the traveling motor 112 and/or the upper driving motor 113, so that the circuit structure is simple, and the detection effect is reliable.

In some embodiments, control switch 157 is coupled to vehicle controller 142 via PLC controller 158. The collected analog signals of the control switch 157 are converted into digital signals by the PLC controller 158, and the digital signals are collectively processed and transmitted to the whole vehicle controller 142 in batches.

In some embodiments, the pipeline truck circuit 153 includes a gravity sensor 159 for detecting the weight of the operator's seat support of the pipeline truck 1, the gravity sensor 159 being electrically connected to the vehicle controller 142; the whole vehicle controller 142 is used for controlling the all-in-one controller 143 to distribute the electric energy of the battery pack 6 according to the gravity value detected by the gravity sensor 159. A gravity sensor 159 is disposed at the driver's seat in the cab 12, and the gravity sensor 159 can detect the gravity value of the driver's seat and transmit the gravity value to the vehicle controller 142 by converting the gravity value into a corresponding signal. The whole vehicle controller 142 is configured to control the all-in-one controller 143 to distribute the electric energy of the battery pack 6 to the traveling motor 112 if the gravity value detected by the gravity sensor 159 is greater than the gravity threshold value. The gravity threshold may be a minimum weight of the driver. For example, when the weight of the adult is 50kg or more and the weight value detected by the weight sensor 159 is 50kg or more, it indicates that the driver is sitting on the driver's seat and is driving immediately or, further, the integrated controller 143 is controlled to distribute the electric power of the battery pack 6 to the running motor 112. When the gravity value detected by the gravity sensor 159 is less than 50kg, it indicates that the driver is away from the driver's seat, and further, the all-in-one controller 143 is controlled to distribute the electric power of the battery pack 6 to the upper driving motor 113. By providing the gravity sensor 159 in this way, the all-in-one controller 143 is caused to reasonably distribute the electric power of the battery pack 6.

In some embodiments, the whole vehicle controller 142 is configured to control the integrated controller 143 to distribute the electric power of the battery pack 6 to the travel motor 112 if the start signal for starting the pipeline cart 1 is received and the gravity value detected by the gravity sensor 159 is greater than the gravity threshold. In this embodiment, when the whole vehicle controller 142 detects the start signal of the pipeline refueling truck 1 and the gravity sensor 159 detects that the support gravity of the driver's seat is greater than the gravity threshold, it indicates that the driver is sitting on the driver's seat and is ready to drive the vehicle, and thus the whole vehicle controller 142 controls the all-in-one controller 143 to distribute the electric power of the battery pack 6 to the traveling motor 112. In some embodiments, the gravity threshold comprises at least one of 50kg, 55kg, 60kg, 65kg, 70kg, 75kg, 80kg, 85 kg.

In some embodiments, the whole vehicle controller 142 is configured to control the all-in-one controller 143 to continue distributing the electric energy of the battery pack 6 to the travel motor 112 if the gravity value detected by the gravity sensor 159 is less than the gravity threshold and the duration of the gravity value less than the gravity threshold is less than the duration threshold when the pipeline cart 1 is in the traveling state. When the line truck 1 is in a driving state, and the gravity value detected by the gravity sensor 159 is smaller than the gravity threshold value for a short period of time (for example, 1s or 2 s), this indicates that the driver on the driver's seat is in a state of physically leaving the driver's seat but standing horse on the driver's seat for the short period of time in the driving state. Therefore, the whole vehicle controller 142 needs to control the all-in-one controller 143 to continue distributing the electric power of the battery pack 6 to the travel motor 112. In some embodiments, the duration threshold comprises at least one of 1s, 2s, 3s, 4 s.

In some embodiments, the pipeline truck circuit 153 includes a key identification sensor 160 for detecting whether the truck start key of the pipeline truck 1 is in a start position, the key identification sensor 160 being electrically connected to the vehicle controller 142; the whole vehicle controller 142 is configured to control the integrated controller 143 to distribute the electric power of the battery pack 6 to the travel motor 112 if the vehicle start key detected by the key identification sensor 160 is at the start position. A key identification sensor 160 is provided at the vehicle start key, and the key identification sensor 160 is used to detect whether the vehicle start key is in the start position. The starting position is the position where the vehicle starting key is located when the pipeline refueling truck 1 is started. When the key identification sensor 160 detects that the vehicle start key is at the start position, it indicates that the driver is about to drive the vehicle, and thus, the whole vehicle controller 142 controls the unified controller 143 to distribute the electric power of the battery pack 6 to the walk motor 112. In this way, the key identification sensor 160 is provided, so that the whole vehicle controller 142 controls the all-in-one controller 143 to reasonably distribute the electric energy of the battery pack 6.

In some embodiments, the whole vehicle controller 142 is configured to control the integrated controller 143 to distribute the power of the battery pack 6 to the travel motor 112 if the gravity value detected by the gravity sensor 159 is greater than the gravity threshold value and if the vehicle start key detected by the key identification sensor 160 is in the start position. In this embodiment, when the gravity sensor 159 detects that the gravity value on the driver's seat is greater than the gravity threshold value and the key recognition sensor 160 detects that the vehicle start key is in the start position, it means that the driver is seated on the driver's seat and ready to drive the vehicle, and thus the whole vehicle controller 142 controls the all-in-one controller 143 to distribute the electric power of the battery pack 6 to the walk motor 112. In this way, the gravity sensor 159 and the key recognition sensor 160 detect whether the pipeline refueling truck 1 is in a driving state or is about to be in a driving state at the same time, so that the whole vehicle controller 142 can control the all-in-one controller 143 to more accurately distribute electric energy according to actual conditions.

In some embodiments, the whole vehicle controller 142 is configured to control the all-in-one controller 143 to distribute the power of the battery pack 6 to the upper drive motor 113 or control the all-in-one controller 143 to disconnect the battery pack 6 from both the travel motor 112 and the upper drive motor 113 if the vehicle start key detected by the key identification sensor 160 is not in the start position. When the key identification sensor 160 detects that the vehicle start key is not in the start position (the vehicle start key is in the closed position or withdrawn), it indicates that the driver is not ready to drive the vehicle, but is likely ready to refuel the aircraft through the upper assembly 4. The whole vehicle controller 142 then controls the all-in-one controller 143 to distribute the electric power of the battery pack 6 to the upper drive motor 113 based on the signal transmitted from the key identification sensor 160. Or when the key recognition sensor 160 detects that the vehicle start key is not at the start position, it indicates that the driver does not prepare to drive the vehicle, and the pipeline refueling truck 1 does not need to refuel the aircraft, so the whole vehicle controller 142 controls the all-in-one controller 143 to power off the battery pack 6, the walking motor 112 and the uploading driving motor 113 according to the corresponding signal sent by the key recognition sensor 160. In some embodiments, the overall vehicle controller 142 may check the status of the upper assembly 4, and determine whether to control the all-in-one controller 143 to distribute power from the battery pack 6 to the upper drive motor 113 or to control the all-in-one controller 143 to disconnect the battery pack 6 from both the travel motor 112 and the upper drive motor 113 based on the status of the upper assembly 4 when the key identification sensor 160 detects that the vehicle activation key is not in the activated position.

In some embodiments, when the key identification sensor 160 detects that the vehicle start key is not in the start position, the whole vehicle controller 142 detects that at least one of the lifting platform 7, the ground well joint 13, the oil filling pipeline assembly 3, the oil pump and the lifting device 49 of the upper assembly 4 is out of position, indicating that the oil filling operation is required, and then controls the all-in-one controller 143 to distribute the electric energy of the battery pack 6 to the upper assembly driving motor 113; the detection of the presence of the above-described components of the upper assembly 4 indicates that no oiling operation is performed, and the all-in-one controller 143 is controlled to disconnect the battery pack 6 from both the travel motor 112 and the upper drive motor 113. In other embodiments, the pipeline truck circuit 153 includes a total power-off switch 170 electrically connected to the vehicle controller 142, and the vehicle controller 142 detects the on-off state of the total power-off switch 170. When the key recognition sensor 160 detects that the vehicle start key is not at the start position and the total power-off switch 170 is closed, stopping and refueling are indicated, and the all-in-one controller 143 is controlled to distribute the electric energy of the battery pack 6 to the upper driving motor 113; when the key identification sensor 160 detects that the vehicle starting key is not at the starting position and the total power-off switch 170 is turned off, stopping flameout is indicated, and no oil is added, the all-in-one controller 143 is controlled to disconnect the battery pack 6 from the walking motor 112 and the upper driving motor 113; when the key identification sensor 160 detects that the vehicle start key is in the start position and the total power-off switch 170 is closed, it indicates that the vehicle is started, and the all-in-one controller 143 is controlled to distribute the electric power of the battery pack 6 to the travel motor 112. Thus, by arranging the key identification sensor 160, the whole vehicle controller 142 controls the all-in-one controller 143 to reasonably distribute the electric energy of the battery pack 6, and the distribution of the electric energy is more reasonable and intelligent. In some embodiments, the total power-off switch 170 is connected to the overall vehicle controller 142 through the PLC controller 158. The PLC controller 158 converts the collected analog signals of the total power-off switch 170 into digital signals, and the digital signals are collectively processed and transmitted to the vehicle controller 142 in batches.

In some embodiments, the pipeline truck circuit 153 includes an indicator light 191, the indicator light 191 being electrically connected to the PLC controller 158 for indicating whether the upper assembly 4 is in place. For example, when any one of the upper assemblies 4 is not mounted in place, the indicator light 191 displays red; when all of the upper assemblies 4 are in place, the indicator light 191 is green. Thus, the operator can conveniently confirm whether the uploading assembly 4 is installed in place in real time, and accordingly the operator can perform corresponding operation.

In some embodiments, the pipeline truck circuit 153 includes a homing sensor 161 for detecting whether the upper assembly 4 is in a home position, the homing sensor 161 being electrically connected to the vehicle controller 142; the whole vehicle controller 142 is configured to control the all-in-one controller 143 to distribute the electric power of the battery pack 6 to the upper drive motor 113 if the homing sensor 161 detects that the upper assembly 4 is not home.

When the upper assembly 4 is not reset, the reset sensor 161 detects a non-reset signal and transmits the non-reset signal to the whole vehicle controller 142, and the whole vehicle controller 142 controls the all-in-one controller 143 to distribute the electric energy of the battery pack 6 to the upper driving motor 113 according to the non-reset signal. In this way, by providing the homing sensor 161, the whole vehicle controller 142 controls the all-in-one controller 143 to reasonably distribute the electric energy of the battery pack 6.

It should be noted that the above technical solution regarding whether the homing sensor 161 detects the homing of the upper assembly 4 is only used for illustrating feasibility, and should not limit the protection scope of the present application.

In some embodiments, homing sensor 161 is coupled to vehicle controller 142 via PLC controller 158. The PLC controller 158 converts the analog signals of the collected homing sensor 161 into digital signals, and the digital signals are collectively processed and transmitted to the whole vehicle controller 142 in batches.

In some embodiments, the pipeline truck circuit 153 includes an emergency switch 162 electrically connected to the whole truck controller 142; the whole vehicle controller 142 is used for controlling the all-in-one controller 143 to disconnect the battery pack 6 from the walking motor 112 and the upper driving motor 113 when the emergency switch 162 is detected to be closed. When the line truck 1 is in an emergency (e.g., a condition in which the drive wheel 9 is flat, the truck head is slamming against an obstacle, etc.), the operator turns off the emergency switch 162. When the whole vehicle controller 142 detects the signal of closing the emergency switch 162, the all-in-one controller 143 is controlled to disconnect the battery pack 6 from both the travel motor 112 and the upper drive motor 113, so that the drive wheel 9 cannot travel and the upper assembly 4 cannot operate. Thus, by setting the emergency switch 162, the whole vehicle controller 142 can detect whether the pipeline refueling truck 1 has an emergency, and if the pipeline refueling truck 1 has an emergency, the whole vehicle controller 142 controls the all-in-one controller 143 to power off the battery pack 6, the traveling motor 112 and the upper driving motor 113, thereby avoiding potential safety hazards further occurring in the pipeline refueling truck 1. In some embodiments, the emergency switch 162 is coupled to the vehicle controller 142 via the PLC controller 158. The collected analog signals of the emergency switch 162 are converted into digital signals by the PLC controller 158, and the digital signals are collectively processed and transmitted to the whole vehicle controller 142 in batches.

In some embodiments, the pipeline truck circuit 153 includes a travel switch 163 disposed above the cab 12 of the pipeline truck 1, the travel switch 163 having a height not lower than the height of the upper assembly 4, electrically connected to the overall truck controller 142; the whole vehicle controller 142 is configured to control the all-in-one controller 143 to disconnect the battery pack 6 from both the travel motor 112 and the upper drive motor 113 when the displacement of the travel switch 163 is detected when the line filler 1 is in the forward travel state. The travel switch 163 is one of position switches (also called limit switches). In this embodiment, a travel switch 163 is provided on the top of the pipeline cart 1. The whole vehicle controller 142 determines whether the top of the line truck 1 touches an obstacle by detecting whether the travel switch 163 is shifted. For example, when the pipeline dispenser 1 passes through the tunnel, if the travel switch 163 is shifted, this means that the height of the tunnel is lower than the height of the pipeline dispenser 1, and the inner roof of the tunnel is lower than the highest position of the upper package 4, and the pipeline dispenser 1 cannot pass through the tunnel. Further, the whole vehicle controller 142 controls the all-in-one controller 143 to power off the battery pack 6, the travel motor 112 and the upper drive motor 113 according to the detected offset signal of the travel switch 163, so that the drive wheel 9 cannot travel and the upper assembly 4 cannot operate. In this way, by setting the travel switch 163, it is determined whether the top of the pipeline refueling truck 1 touches an obstacle, and the upper assembly 4 can pass through to control the distribution of electric energy by the all-in-one controller 143, thereby avoiding potential safety hazards which may occur in the pipeline refueling truck 1. In some embodiments, travel switch 163 is coupled to vehicle controller 142 via PLC controller 158. The PLC controller 158 converts the acquired analog signals of the travel switch 163 into digital signals, and the digital signals are collectively processed and transmitted to the vehicle controller 142 in batches.

It should be noted that the above technical solution regarding how the vehicle controller 142 detects the state of the pipeline refueling truck 1 is only for illustrating feasibility, and should not limit the protection scope of the present application.

In some embodiments, the pipeline truck circuit 153 includes a CAN controller 164 connected between the upper motor controller 156 and the upper assembly 4 for enabling data interaction of the upper motor controller 156 with the upper assembly 4. CAN controller 164 may enable data interaction between the on-board motor controller 156 and the on-board components 4. The CAN controller 164 transmits a control command of the upper motor controller 156 to the upper assembly 4, and the upper assembly 4 performs an operation according to the control command. The CAN controller 164 may send the operation data of the upper assembly 4 to the upper assembly motor controller 156, and the upper assembly motor controller 156 may determine the operation data of the upper assembly 4 to adjust the operation state of the upper assembly 4. Thus, the data interaction between the upper motor controller 156 and the upper assembly 4 is realized through the CAN controller 164, and the reliability of the pipeline refueling truck 1 is improved. In some embodiments, the operational data of the upper assembly 4 may be uploaded to an instrument panel (not shown) within the cab 12 to facilitate real-time monitoring of the operational status of the upper assembly 4 by the driver.

In some embodiments, the pipeline truck 1 further comprises a transmission electrically connected between the travel motor 112 and the drive wheel 9 for varying the rotational speed of the travel motor 112.
