In the description of the present invention, the "up" and "down" orientation or positional relationship is based on the normal use state of the aerial work equipment, i.e., the orientation or positional relationship shown in fig. 1, 6 and 8, wherein "vertical" is the up-down direction of fig. 1, and "down" is the down direction of fig. 6. It is to be understood that such directional terms are merely for convenience in describing the present invention and to simplify the description, and are not intended to indicate or imply that the device or element so referred to must be in a particular orientation, constructed and operative in a particular orientation, and therefore should not be taken as limiting the invention.

Self-walking automobile body mean one kind can rely on self power walking, but do not set up the vehicle of driver's cabin, for example self-walking high altitude construction car, self-walking construction elevator etc. the walking speed of this self-walking automobile body is slower, and can only walk in relative confined place such as factory, construction site when self-walking, can drag along with the tractor and hang the travel on the road when pulling, be different from the general motor vehicle that can travel on roads such as highway.

The embodiment of the utility model provides an aerial working equipment. As shown in fig. 1, 2 and 7, the aerial working equipment comprises a self-walking vehicle body 2 and a telescopic arm support 1 with a plurality of arm sections 1-1 which are mutually sleeved, wherein the self-walking vehicle body 2 comprises a chassis 2-1, the chassis 2-1 comprises a vehicle frame 2-11 and an axle 2-2, the axle 2-2 is installed on the vehicle frame 2-11, the ground clearance of the axle 2-2 is larger than that of the vehicle frame 2-11, the telescopic arm support 1 is connected with the vehicle frame 2-11, and the telescopic direction of the telescopic arm support 1 is vertical.

The above-mentioned "ground clearance" refers to the distance between the lowest point of a certain component of the chassis and the supporting plane of the chassis. For example, the vertical distance between the lowest part of the axle and the ground is larger than the vertical distance between the lowest part of the vehicle frame and the ground. The axle may be a steer axle, a tag axle, a drive axle or a steer-drive axle.

Generally, the axles are all installed below the vehicle frame, namely the ground clearance of the axles is smaller than that of the vehicle frame, but the height of the chassis of the structure is higher, so that the overall size of the aerial work equipment is larger. In addition, most of high-altitude operation equipment for airplane deicing adopts folding arms, the folding arms need to occupy more installation space, even if some high-altitude operation equipment adopts telescopic arm frames, the telescopic arm frames generally change the pitching angle through variable amplitude oil cylinders, and the telescopic arm frames are placed at the top of the high-altitude operation equipment during recovery, so that the height space of the whole airplane is occupied.

Accordingly, prior art high altitude construction equipment for deicing aircraft generally cannot be transported in the cargo compartment of the aircraft. The chassis of the aerial working equipment is provided with the axle arranged above the frame, so that the ground clearance of the axle is larger than that of the frame, namely, the height of the frame is reduced, the overall height of the chassis is further reduced, and meanwhile, the telescopic arm support in the vertical direction is matched with the telescopic direction, so that the overall size of the aerial working equipment is more compact, and the aerial working equipment can be placed in a cargo hold of an airplane to be transported along with the airplane.

Furthermore, the telescopic arm support 1 further comprises a plurality of telescopic cylinders 1-2, two adjacent arm sections 1-1 are connected through one telescopic cylinder 1-2, all the telescopic cylinders 1-2 are arranged on the outer side of the corresponding arm section 1-1, and the telescopic cylinders 1-2 can drive the corresponding arm sections 1-1 to extend and retract through extension. When the telescopic arm support 1 is in a retraction state, namely all the telescopic cylinders 1-2 are retracted to the right position, all the telescopic cylinders 1-2 are distributed at intervals on the periphery of the arm section 1-1 positioned at the outermost side.

Compared with the traditional arrangement mode that the telescopic cylinders are arranged in the cavities of the arm sections, the arrangement mode of the telescopic cylinders adopted in the embodiment can enable the mutually sleeved arm sections to be arranged more compactly on the cross section (refer to fig. 5), and because the telescopic cylinders are not required to be arranged by reserving enough space in the arm sections, the telescopic arm support of the embodiment can increase the total height of the telescopic arm support after being stretched out by sleeving more arm sections with smaller calibers under the condition of ensuring that the overall dimension of the telescopic arm support is not increased, so that the loss of the operation height of the telescopic arm support caused by the reduction of the overall height of the high-altitude operation equipment is made up. In addition, the telescopic cylinder has potential safety hazards such as cracking and the like after being used for a long time, so that a user can conveniently observe whether the telescopic cylinder is abnormal or not by arranging the telescopic cylinder on the outer side of the arm section, and the connecting pipeline and the telescopic cylinder are conveniently maintained and replaced.

The advantage of sharing one electric liquid pipe support with the hydraulic pipe and the electric wire is that the oil pipe winding and the electric wire winding can be arranged more compactly while the number of used pipeline supports is reduced.

In addition, in this embodiment, the diameter of the water pipe coil is almost twice the diameter of the oil pipe coil, and is three times the diameter of the electric wire coil, the water pipe coil needs to occupy more installation space, and the aperture of the water pipe is the largest compared to the electric wire and the hydraulic pipe, therefore, in order to make the arrangement of the water pipe coil, the oil pipe coil and the electric wire coil more compact, the oil pipe coil 5b and the electric wire coil 5c are disposed on the same side of the telescopic boom 1, and the water pipe coil 5b is disposed on the side of the telescopic boom 1 away from the oil pipe coil 5b and the electric wire coil 5 c.

The electric liquid pipe support 4-2c and the water pipe support 4-2b are symmetrically arranged along the rotation center of the guide support 4-1, which is equivalent to that after the guide support rotates clockwise or anticlockwise for 180 degrees along the rotation center, the electric liquid pipe support can move to the position where the electric liquid pipe support is located before the guide support rotates, and the water pipe support can move to the position where the electric liquid pipe support is located before the guide support rotates, so that the water pipe, the electric wire and the hydraulic pipe can be prevented from being interfered in the movement process.

The winding process of the water pipe 6a on the guide bracket 4-1 is briefly described below by taking the water pipe 6a as an example:

as shown in fig. 1, 4 to 11, in an initial state, the telescopic boom 1 is in a retracted state, when the telescopic boom 1 extends out in a vertical direction, the water pipe winding disc 5a continuously releases water through rotation, and when the telescopic boom 1 extends to a proper height, the water pipe winding disc 5a stops rotating. At this time, the telescopic boom 1 may need to be rotated according to the operation situation, and the winding manner of the pipeline on the guide bracket 4-1 is completely the same when the telescopic boom 1 of the embodiment rotates clockwise by 150 degrees, and also rotates counterclockwise by 150 degrees, and rotates counterclockwise and clockwise. Taking the counterclockwise rotation of the telescopic boom support 1 in fig. 12 as an example, when the telescopic boom support 1 rotates counterclockwise, the water pipe support 4-2b drives the water pipe 6a to move together, and meanwhile, the water pipe winding disc 5a continues to pay off by rotating, in practical use, a driving device such as a rotary motor can be arranged on the water pipe winding disc 5a, and the water pipe winding disc 5a is driven by the rotary motor to rotate and pay off, so that the water pipe 6a can be wound on the outer peripheral surfaces of the guide rods 4-11. Similarly, when the telescopic boom support 1 which is rotated in place needs to be retracted to the initial position before rotation, the water pipe support 4-2b can also guide the water pipe 6a to move together in the opposite direction, meanwhile, the water pipe winding disc 5a can also be driven by a driving device such as a rotary motor and the like to rotate reversely to take up the water pipe, and when the telescopic boom support 1 is retracted to the initial position, the water pipe 6a is separated from the guide rod 4-11 and is restored to the state before winding on the guide support 4-1, namely the state shown in fig. 11.

The winding mode of the hydraulic pipe and the electric wire on the guide bracket is completely the same as that of the water pipe, and the description is omitted.

Because the electric liquid pipe support and the water pipe support are symmetrically arranged along the rotation center of the guide support, and the telescopic arm support of the embodiment rotates within the range of +/-150 degrees, no matter the telescopic arm support rotates anticlockwise or clockwise, the three pipelines of the water pipe, the hydraulic pipe and the electric wire cannot be wound together to influence the normal rotation of the telescopic arm support.

The embodiment provides high-altitude operation equipment, and the chassis of the high-altitude operation equipment is designed into a structural form that a vehicle bridge is arranged above a vehicle frame, and is matched with a telescopic arm support with the telescopic direction being the vertical direction, so that the whole vehicle size of the high-altitude operation equipment is more compact, and the aerial transportation is facilitated.
