High-precision positioning operation device for overhead working truck

Technical Field

The utility model relates to an aerial working equipment technical field, in particular to aerial working is automobile-used can realize operation device of high accuracy location.

Background

The high-altitude operation vehicle is a special vehicle for transporting workers and using equipment to the high altitude to install, maintain and clean equipment located at the high altitude, has the advantages of good operation performance, high operation efficiency, safe operation and the like compared with the traditional operation modes of taking scaffolds, ladders and the like, and is widely applied to the infrastructure industries of electric power, traffic, petrifaction, communication, gardens and the like at present.

The high-altitude operation vehicle has various classification modes, is classified according to the form of an arm support, can be divided into two basic forms of a straight arm type and a crank arm type, is classified according to the form of a working arm, and has four basic forms, namely: vertical lifting type, folding arm type, telescopic arm type and mixing arm type. The high-altitude operation equipment is generally provided with an amplitude variation mechanism, a horizontal rotating mechanism, a balancing mechanism and a traveling mechanism, and the movement of a manned or robot working bucket in the vertical and horizontal directions is realized by the amplitude variation mechanism and the horizontal rotating mechanism; the included angle between the working bucket and the horizontal plane is kept unchanged by the balance mechanism, and the workplace is transferred by the walking mechanism. However, if the working environment is complex, for example, when the high-voltage wire transmission line is connected in high altitude, the difficulty is increased for high-altitude connection due to the irregular winding track, the thick wire diameter of the coil, the large bending force, the limited bending movement space and the like. In addition, the folding arm overhead working truck has the defects of instability, even rollover accidents in severe cases due to factors such as artificial misoperation or severe natural conditions in the working process, so that the working truck is damaged and the life safety of operators and surrounding pedestrians is threatened. Therefore, when designing the whole aerial work vehicle, it is necessary to analyze the stability of the whole aerial work vehicle. Therefore, an operation device capable of accurately positioning an operation area and having high safety is urgently needed.

When general aerial work equipment is used and aerial work is carried out, the following defects exist: 1. the existing aerial work platform is generally a single operation platform, namely, only one person is allowed to operate each time of operation, the operation space is limited, the operation efficiency is low, and the workload of operators is large. 2. The existing aerial work platform is a movable aerial work platform, a spider type aerial work platform, a self-propelled aerial work platform or a scissor type aerial work platform, and the existing aerial work platform is fixed in the horizontal direction, so that the requirements for multi-angle operation cannot be met. When the operation position changes, the position of the suspension arm needs to be adjusted to realize the position adjustment of the aerial work platform, so as to achieve the purpose of accurately operating the designated operation area; even if the working position changes slightly, the position of the suspension arm needs to be adjusted to realize the operation, and the use is not flexible, so that the working quality is poor, and the working efficiency is low. 3. The existing aerial work platform reaches the designated work area in a mode of lifting, improving and moving the whole lifting arm, so that the aerial work platform is extremely inflexible to use and low in work efficiency.

For example, patent CN 201472231U discloses a mast type aerial work vehicle with a laterally movable working platform, which includes a vehicle chassis, a lifting mast fixed on the vehicle chassis, and a working platform, wherein a support is fixed on the lifting mast, the working platform is disposed on the support through at least two pairs of kinematic pairs composed of a rail and a guide wheel, the rail and the guide wheel are disposed on the working platform and the support, respectively, and a lateral movement driving device is disposed between the working platform and the support. The patent can realize the lateral movement of the working platform by the lateral movement driving device, thereby achieving the purposes of approaching the working target to work and not obstructing the running of other vehicles on the road. But has the following disadvantages that, firstly, the platform is a single platform, and the working efficiency is low. Secondly, the working platform in the patent specifically realizes the lateral movement through the kinematic pair, and the running track is a straight line, so that the purpose of working by the change of the working position within a certain distance from the working platform to the working target position can be realized. However, if the distance exceeds this range, the vehicle chassis does not touch the work target and the position of the work target needs to be adjusted to continue the work.

Further patent CN110740966A discloses an aerial work platform automatically positioned in a compact transport position. The lifting platform comprises a frame (2), a working platform (10) and a lifting structure (20), wherein the lifting structure (20) comprises at least one cantilever (26) capable of being lifted and lowered and a swing arm (30) which is arranged at the top end of the cantilever (26) and supports the platform (10). It also comprises sensors (51, 52) for detecting the approach of the platform (10) to an obstacle. The onboard electronics automatically place the aerial work platform in a compact position upon request of the operator by controlling the lifting structure (20) in view of the surrounding environment in dependence on signals from the sensors (51, 52). Thereby automatically bringing the aerial platform into a compact position in which the aerial platform is suitable for transport on a trailer or a flat bed truck, taking into account the surroundings of the aerial platform. However, this patent does not solve the technical problem that the entire lifting arm needs to be raised to achieve the purpose when the working area needs to be raised to a small extent and the height of the fluctuation needs to be reduced, and this results in the working platform being inflexible to use, having low working efficiency and high construction cost.
