Description
Technical Field
The present invention relates to an inclination correction device on which a gyro turntable is mounted, and an aerial ladder/cantilever-mounted vehicle in which an aerial ladder or cantilever can be extended, lowered, or rotated.
Background
As a boom/aerial ladder carrying vehicle such as a fire truck or an aerial vehicle on which a boom or an aerial ladder capable of performing telescopic, lifting, or swinging operations is carried, a vehicle having a gyro turntable type tilt correction device for automatically keeping the boom or the aerial ladder horizontal on a tilted ground is known.
For example, patent document 1 discloses an aerial ladder truck in which, when the aerial ladder is parked on an inclined floor, the support member is moved in a spherical surface with respect to the vehicle body so as to be in an up-down direction with respect to a pivot shaft of the support member of the vehicle body and in a horizontal direction with respect to a pivot shaft of an aerial ladder attached to the support member, first and second search beams are emitted from one of the aerial ladder and an aerial ladder holder and reach the other, both of the first and second search beams are detected when the aerial ladder is located at a support position by the aerial ladder holder in a rotation direction at a center of the pivot shaft, the first search beam is detected when an interval from the support position to one of the rotation directions is within a set range, the second search beam is detected when an interval from the support position to the other rotation direction is within a set range, and the aerial ladder is rotated in a direction in which only one search beam is detected.
Patent literature: japanese patent laid-open No. 2000-350791.
In consideration of the height restrictions in roads, garages, and the like, it is sometimes required to set the total height of the aerial ladder/boom car to be equal to or less than a predetermined level. However, since the aerial ladder or the boom of the aerial ladder/boom-mounted vehicle is placed laterally above the cab and the vehicle body, the overall height of the vehicle tends to be large. In addition, in the case of the gyro-turntable-type tilt correction device, since the clearance between the aerial ladder or the cantilever and the cab or the like is set large in consideration of interference with the cab or the like at the time of tilt correction, the position of the aerial ladder or the cantilever at the time of storage is raised, and the overall height of the vehicle is increased.
Further, patent document 1 discloses facilitating the operation of accommodating the aerial ladder, and does not attempt to reduce the overall height of the vehicle.

According to the present embodiment, the total height of the vehicle can be suppressed without extending the carrier device during running, and therefore the vehicle can easily pass through roads, garages, and the like having a height limitation. In addition, when the tilt correction is performed on the tilted floor surface by the gyro turntable, the carrier is extended to expand the gap, so that the tilt correction can be performed without causing interference between the aerial ladder or the cantilever and the cab or the vehicle body.
The second embodiment of the present invention is configured as follows: the aerial ladder/boom-mounted vehicle according to the first embodiment is provided with a control device that controls such that a force in a lowering direction is applied to the aerial ladder or the boom during extension of the carrying device.
According to the present embodiment, the aerial ladder or the boom can be reliably prevented from floating from the carrying portion while being lifted by the carrying device.

Examples
Hereinafter, an aerial ladder/boom car according to an embodiment of the present invention will be described. In the present embodiment, the description is given as an aerial ladder vehicle on which an aerial ladder is mounted, but the case of a boom vehicle on which a boom is mounted is basically the same.
Fig. 1 is a view showing an aerial ladder truck according to the present embodiment.
The aerial ladder loading vehicle (fire-fighting aerial ladder vehicle) includes a cab 10 located at the front of the vehicle and having a driver's seat, a vehicle body 20 located at the rear of the cab 10, an aerial ladder 30 stored in a lying state above the cab 10 and the vehicle body 20, a gyro turntable 40 located at the rear of the vehicle body 20, a support frame 50 located on the gyro turntable 40 and supporting the rear end of the aerial ladder 30, a carrying device 60 carrying and supporting the aerial ladder 30 from below at a position close to the rear surface of the cab 10, a basket 70 attached to the front end of the aerial ladder 30, and hydraulic legs 80.
The scaling ladder 30 is provided with a plurality of layers of ladder bodies 31, telescopic cylinders 32 for telescopic movement of the ladder bodies 31, lifting cylinders 33 for lifting the ladder bodies 31, and bending cylinders 34 for adjusting bending angles of the bending layers.
Fig. 2 is a view showing the carrying device, fig. 2 (a) shows an unextended state, and fig. 2 (b) shows an extended state. In fig. 2 (a) and (b), the middle is a front view, the left side is a left side view, and the right side is a right side view.
The carrying device 60 includes a carrying portion 61 having a carrying surface on which a part of the aerial ladder 30 in a lying state is carried, and a carrying holding portion 62 for holding the carrying portion 61 from below.
The carrier 61 has protruding portions 61a protruding upward at both ends.
The load holding portion 62 has a pair of leg portions 62a and a pair of arm portions 62b. The leg portions 62a are vertically erected, and one leg portion 62a and the other leg portion 62a are aligned in the vehicle width direction with a gap smaller than the entire length of the bearing portion 61.
The arm portions 62b are erected obliquely from the respective upper surfaces of the one leg portion 62a and the other leg portion 62a toward the longitudinal center of the bearing portion 61, and the upper end of the one arm portion 62b and the upper end of the other arm portion 62b meet at a connection portion with the bearing portion 61.
The bearing portion 61 is raised by the extension of the bearing holding portion 62. The maximum raising position of the carriage 61 is determined in consideration of the total height of the vehicle, the degree of interference between the aerial ladder 30 and the cab 10 at the time of inclination correction, and the like, and the distance from the maximum lowering position is set to 200mm, for example.
A carrier cylinder 63 as a hydraulic cylinder for carrying the expansion and contraction of the holding portion 62 is accommodated in each of the one leg portion 62a and the other leg portion 62a. As the carrier cylinders 63, one cylinder may be provided between the leg portions 62a, but as in the present embodiment, by providing two carrier cylinders 63 and disposing them in a laterally dispersed manner, the diameter of each carrier cylinder 63 and the diameter of the leg portion 62a can be made relatively smaller than in the case where one carrier cylinder 63 is provided. In addition, the carrying portion 61 carrying the aerial ladder 30 is easily lifted up smoothly.
Fig. 3 is a view showing the load holding portion and the oil tank.
In the space created between one leg portion 62a and the other leg portion 62a, an oil tank 90 is provided that stores oil to be supplied to hydraulic equipment such as the expansion cylinder 32, the lift cylinder 33, the bending cylinder 34, and the carrier cylinder 63. By providing the oil tank 90 that requires a relatively large installation space between the leg portions 62a, the installation space for other equipment and the like can be easily secured as compared with the case where the oil tank 90 is provided at another position, and the degree of freedom of arrangement increases. Further, since the carrier 60 and the tank 90 are unitized and integrally handled, the mounting work of the carrier 60 and the tank 90 can be performed more effectively than before.
In addition, by disposing the carrier 60 and the oil tank 90 on the front side of the vehicle body 20 near the rear surface of the cab 10, it is easy to dispose other equipment or the like on the rear side of the vehicle body 20.
Fig. 4 is a view showing the lifting of the aerial ladder by the carrying device on the flat ground, where fig. 4 (a) shows a state in which the aerial ladder is not lifted, and fig. 4 (b) shows a state in which the aerial ladder is lifted.
When the intermediate portion between the rear end and the front end of the aerial ladder 30 in the housed state is placed on the carrying portion 61 and the carrying holding portion 62 is not extended, the aerial ladder 30 is substantially horizontal as shown in fig. 4 (a). In this state, the total vehicle height is low compared to a state in which the aerial ladder 30 is inclined forward and upward by extending the load holding portion 62, and therefore, during a non-use time of the aerial ladder 30 such as during traveling, the aerial ladder 30 is made substantially horizontal without extending the load holding portion 62, and thus, the total vehicle height is suppressed to be within a predetermined height, and the vehicle can easily pass through roads, garages, and the like having a height restriction.
The gyro turntable 40 attached to the vehicle body 20 has a wedge-shaped lower inclined plate 41, a wedge-shaped upper inclined plate 42 located on the lower inclined plate 41, and a disk-shaped upper circular plate 43 located on the upper inclined plate 42, and is used for correcting the inclination of the aerial ladder 30 on the inclined floor. The upper surface of the lower swash plate 41 is inclined, and the lower surface of the upper swash plate 42 is inclined, and the inclined surfaces are connected to each other. A support frame 50 is mounted on the upper circular plate 43.
The lower swash plate 41 and the upper swash plate 42 are rotatable, respectively, and the horizontal degree of the upper disc 43 is adjusted by a combination of the rotational position of the lower swash plate 41 and the rotational position of the upper swash plate 42. In the inclination correction, the lower swash plate 41 is rotated to a predetermined rotation position set for the lower swash plate 41, and the upper swash plate 42 is rotated to a predetermined rotation position set for the upper swash plate 42 with the lower swash plate 41 fixed to the predetermined rotation position.
The predetermined rotational positions to be given to the lower swash plate 41 and the upper swash plate 42 are determined based on the amount of inclination of the vehicle body 20 obtained by the sensor.
Fig. 5 is a diagram showing a state in which the tilt correction of the aerial ladder is performed on the tilted ground surface. In this embodiment, fig. 5 (a) shows a state in which the aerial ladder is lifted up by the extension of the load bearing and holding portion to perform tilt correction, and fig. 5 (b) shows a state in which interference with the cab occurs without lifting up the aerial ladder to perform tilt correction, as a comparative example.
There are various types of inclination correcting devices according to the manner. In the gyro turntable type tilt correction device, when an aerial ladder vehicle that is parked at a fire site or the like is tilted in the front-rear direction or the left-right direction due to the tilt of the ground, the upper disk 43 of the gyro turntable 40 to which the support frame 50 is attached is operated so as to be horizontal when a fire extinguishing operation, a rescue operation or the like is started.
In the gyro-turntable type tilt correction device, the tilt correction is performed by rotating the upper swash plate 42 and the lower swash plate 41 and changing the relative rotational positions, but in order to avoid interference between the aerial ladder 30 and the cab 10 or the like at the time of tilt correction, it is necessary that the lower surface of the aerial ladder 30 and the upper surface of the cab 10 or the like be separated by a predetermined distance or more.
In the present embodiment, as shown in fig. 4 (a), the carrier portion 61 is set to the maximum descent position so as not to extend the carrier holding portion 62 in order to reduce the total height of the vehicle as much as possible, and therefore the clearance (clearance) between the lower surface of the aerial ladder 30 and the upper surface of the cab 10 is relatively small. At the time of inclination correction, since the front end side of the aerial ladder 30 swings by rotation of the upper inclined plate 42 of the gyro turntable 40 with respect to the lower inclined plate 41 and the aerial ladder 30 slides on the roller of the bearing portion 61 so that the contact position of the aerial ladder 30 with the bearing portion 61 is shifted, if the inclination correction is performed while keeping a narrow gap in traveling on the inclined ground, the aerial ladder 30 interferes with the cab 10 as shown in fig. 5 (b). In addition, although fig. 5 (b) shows the case of the inclined floor surface inclined forward and upward, the same problem occurs when the inclined correction is performed on the inclined floor surface inclined forward and downward or on the inclined floor surface inclined to either the left or right.
Therefore, when the gyro turntable 40 is used for inclination correction, as shown in fig. 4 (b), the load holding portion 62 is extended and the load portion 61 is raised to the maximum raised position on the inclined floor surface, so that the front end side of the aerial ladder 30 is lifted, and the lower surface of the aerial ladder 30 is sufficiently separated from the upper surface of the cab 10 or the like.
By performing tilt correction in this state, even if the tip end side of the aerial ladder 30 swings due to rotation of the gyro turntable 40 and the contact position of the aerial ladder 30 and the carrier 61 is shifted, tilt correction can be completed without causing interference between the aerial ladder 30 and the cab 10 or the like as in fig. 5 (a).
A control device (not shown) is provided in the aerial ladder truck. The control device controls so that a force in the descending direction is applied to the aerial ladder 30 by the lifting cylinder 33 in the middle of lifting the aerial ladder 30 by the extension of the load holding portion 62. This can reliably prevent the aerial ladder 30 from being lifted from the carrying portion 61 while being lifted by the carrying device 60. The control device appropriately controls the force in the descending direction in the middle of the lifting of the aerial ladder 30 by the carrier 60 to balance the force in the ascending direction of the carrier 60, thereby allowing the carrier 60 to ascend.
The control device controls the lift cylinder 33 to apply a force in the lowering direction to the aerial ladder 30 even when the gyro turntable 40 is rotated to perform tilt correction and when the load holding portion 62 is lowered to lower the aerial ladder 30 after the completion of the work.
In addition, as in the prior art, the loading device is fixed, and when traveling in a state where the lower surface of the aerial ladder 30 is sufficiently away from the upper surface of the cab 10 or the like, the vehicle can be directly transferred to the tilt correction when parked on the tilt floor. On the other hand, in the aerial ladder truck of the present invention, it is necessary to extend the load holding portion 62 to raise the aerial ladder 30 before the tilt correction is performed by the gyro turntable 40, and therefore, the time required for the tilt correction increases as compared with the conventional one.
Accordingly, the control unit rotates the lower swash plate 41 to a predetermined rotation position in parallel with the extension of the load holding portion 62. When the sensor detects that the carrier 61 reaches the maximum raised position and the lower swash plate 41 rotates to the predetermined rotation position, the control unit rotates the upper swash plate 42 to the predetermined rotation position. This can shorten the time taken for the tilt correction, as compared with the case where the tilt correction is started by the gyro turntable 40 after the completion of the ascent of the carrier section 61.
Further, when the lower swash plate 41 rotates to a predetermined rotation position, the upper swash plate 42 also rotates together, and therefore the relative rotation position of the lower swash plate 41 and the upper swash plate 42 is unchanged, and the pitch angle of the upper disc 43 is constant. Therefore, even if the lower swash plate 41 is rotated during the lifting of the bearing portion 61, the aerial ladder 30 does not interfere with the cab 10.
When the fire extinguishing operation or the like ends and the aerial ladder 30 is returned to the storage position and the aerial ladder 30 is placed on the carrier 61, the control unit rotates the upper swash plate 42 to the rotation position before the inclination correction and then rotates the lower swash plate 41 to the rotation position before the inclination correction, but retracts the carrier holding portion 62 in parallel with the rotation of the lower swash plate 41. This can shorten the time taken for the withdrawal work, compared with the case where the carrier holding portion 62 is retracted after the completion of the rotation of the lower swash plate 41.
