Referring to fig. 1 to 3, an embodiment of the present application provides a dual-purpose operation chassis for a track, which includes: a first chassis frame 10, a second chassis frame 20, and a driving element.
The rail dual-purpose operation chassis provided by the embodiment of the application can be applied to an aerial operation vehicle, and the aerial operation vehicle is a special vehicle for conveying workers and using equipment to the site and carrying out aerial operation. The overhead working truck comprises a walking chassis, an arm support arranged on the chassis and a working platform. The high-altitude operation vehicle can be a straight-arm high-altitude operation vehicle or a crank-arm high-altitude operation vehicle. Some existing aerial work vehicles are provided with two sets of wheels, namely road wheels and track wheels. When the road surface walking is switched to the rail walking operation, the direction and the position of the vehicle body need to be continuously adjusted to enable the rail wheels to be in contact fit with the rail, and more operations are needed, so that the operation is inconvenient.
The first chassis frame 10 is provided with a first type of wheels 11 capable of running on the ground, and the first type of wheels 11 can be rubber wheels and can be used for running on the ground. Specifically, the first chassis frame 10 is arranged with front and rear pairs of wheels 11 of the first type. The first chassis frame 10 may be mounted with a power source for driving the first type of wheels 11 to rotate. The power source can be an internal combustion engine, an electric motor and a hydraulic motor.
The second chassis frame 20 is positioned above or below the first chassis frame 10, and is provided with a movable arm 21; the movable arm 21 is provided with a second type wheel 22 capable of running on the track, and the second type wheel 22 can be a metal wheel. The movable arm 21 can adjust the height of the second type wheel 22 to press down on the rail to lift the first type wheel 11 or lift up off the rail to land the first type wheel 11. When the high-altitude operation vehicle runs on a common road surface, the second type wheels 22 can be lifted by adjusting the movable arms 21, so that the first type wheels 11 land, and at the moment, the first type wheels 11 drive the high-altitude operation vehicle to run under the driving of a power source. When the overhead working truck switches from the road traveling to the rail traveling, the second type wheels 22 can be pressed down the rail by adjusting the movable arms 21, at this time, the first type wheels 11 are separated from the ground, and the overhead working truck is driven by the second type wheels 22 to travel along the rail.
In the embodiment of the present application, the driving element can drive the first chassis frame 10 to rotate relative to the second chassis frame 20, and when the overhead working truck switches from road running to track running, the contact fit with the track can be more conveniently realized by adjusting the position and the direction of the second type wheels 22. The driving element can be an electric mechanism, a hydraulic actuator or a pneumatic mechanism. In some embodiments, the driving element is a hydraulic motor or a rotary cylinder, or other electric mechanism capable of driving the first chassis frame 10 to rotate relative to the second chassis frame 20.
In some embodiments, the second chassis frame 20 is hinged with a movable arm 21 on each side; an oil cylinder or an air cylinder 23 capable of driving the movable arm 21 to move up and down is installed between the second chassis frame 20 and the movable arm 21. The movable arm 21 is driven by a cylinder 23 to rotate around the hinged position to lift or press the second type wheel 22.
Further, the movable arm 21 includes: two first movable arms 211 provided at a first side of the second chassis frame 20, and one second movable arm 212 provided at a second side of the second chassis frame 20; wherein, each first movable arm 211 is correspondingly provided with a second wheel 22; a pair of wheels 22 of the second type are mounted on the second movable arm 212. Each of the second wheels 22 may form one contact position with the rail, the two second wheels 22 on the second movable arm 212 on the second side may simultaneously contact the rail to form two contact positions, and then the two second wheels 22 on the two first movable arms 211 on the first side may be separately adjusted to contact the rail, so that the four second wheels 22 may be adjusted to simultaneously contact the rail, so that the whole chassis is balanced.
In addition, the movable arm 21 can support the whole chassis when being pressed down, and can be used for crossing uneven road surfaces. Therefore, the movable arm 21 can increase the passing ability of the work chassis under some road conditions by being lifted up and pressed down.
Further, the movable arm 21 is provided with a hydraulic motor or an electric motor 213 for driving the second type wheel 22 to rotate.
It should be noted that the above dual-purpose operation chassis for rails is used for various types of operation vehicles, and is not limited to aerial operation vehicles, and the dual-purpose operation chassis for rails proposed in the above section can be used for simultaneously walking on rails and the ground, and can be flexibly switched between the rails and a common road surface.
In the present application, the dual-purpose rail working chassis includes a first chassis frame 10, a second chassis frame 20 located above or below the first chassis frame 10; the driving element drives the first chassis frame 10 to rotate relative to the second chassis frame 20. The technical scheme of the application has the following technical effects: the first chassis frame and the first chassis frame can rotate relative to the second chassis frame, and when the ground running is switched to the track running, the position and the direction of the second type of wheels are adjusted, so that the contact matching with the track is conveniently realized. And secondly, the movable arm can be lifted up and pressed down, so that the passing capacity of the operation chassis under some road conditions can be increased. In the third, during the operation on the ordinary road, the first type wheel 11 is grounded, and the movable arm 21 can be used as a support leg to play an auxiliary supporting role so as to effectively improve the stability of the operation vehicle. Therefore, the weight of the whole machine can be effectively reduced and the safety of the whole machine can be improved when the working radius and the height are the same.
Referring to fig. 2 and 3, the embodiment of the application also provides an aerial work platform, which is provided with the dual-purpose rail work chassis provided in the above part, and an aerial work arm support 30 mounted on the dual-purpose rail work chassis.
