Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of high-voltage transmission line inspection devices, and in particular to a real-time adjustable clamping walking device for a flying-walking inspection robot for an overhead transmission line. BACKGROUND

[0002] With the development of modern power system, the mileage of high-voltage transmission lines in China is increasing rapidly, and the traditional manual inspection can no longer meet the growing demand for transmission line inspection. Therefore, a series of transmission line inspection devices have been developed and designed in China, among which representative new transmission line inspection devices include inspection robots and inspection aircraft.

[0003] However, the existing inspection robots mainly focus on a double-arm line-hanging inspection robot, which needs manpower or needs to install special lifting equipment on the electric tower line for the robot to cross the electric tower, and the robot is heavy in size and complicated in the design and control system, that is, the inspection robot has the shortcomings of great difficulty in designing the whole machine, inflexible in crossing the line and avoiding obstacles. In some schemes, unmanned aerial vehicles (UAVs) are used for power line inspection, and the unmanned aerial vehicle inspection can also be divided into three types of inspection aircraft carriers: a helicopter, a large UAV and a rotary-wing UAV. The Helicopter and large UAVs can carry sensing equipment for large-area joint operation at the same time, but it is difficult to carry out fine inspection close to the transmission lines, and the collection cost and technical threshold are too high. Moreover, the helicopter is also restricted by weather and environment. The rotary-wing UAV is small in size and high in inspection line, but has disadvantages of limited load and short battery life, that is, the UAV inspection cannot achieve long-term inspection.

[0004] In order to solve the above technical problems, a novel inspection robot for a transmission line is proposed by the latest research in China. The robot can combine the functions of flying and line-hanging inspection and achieve the automatic switching of functions in the air. The appearance of the flying-walking inspection robot for a transmission line, which integrates the functions of line-hanging inspection and flying obstacle crossing, provides a technical solution for the field of power line inspection with both flexible obstacle crossing and long-distance fine inspection ability. Aiming at such as flying-walking multi-rotor automatic inspection device for an overhead transmission line, that is, a flying-walking inspection robot, when an original clamping walking device of the inspection robot is on a curved power line and walks by hanging on the line, one end of the clamping walking device will be slightly tilted due to its own rigid structure, resulting in uneven stress on the clamping walking wheel, which makes the clamping walking wheel cannot well adapt to various line types. When the clamping mechanism is on a large slope, the inspection robot is prone to slip. In a case of slipping in the process of hanging on the line, the inspection robot may tilt as a whole, especially when inspecting on the power line that is dancing due to wind interference, and the inspection robot may be accidently detached, resulting in unnecessary economic losses.

[0005] Therefore, for the problems in the prior art of a flying-walking multi-rotor automatic inspection device for the overhead transmission line, there is an urgent need for a clamping walking device for a flying-walking inspection robot which is suitable for a variety of line shapes and ensures that there is no crash.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] To make the objectives, technical solutions and advantages of the present disclosure more clearly, the following clearly and completely describes the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are merely a part rather than all of the embodiments of the present disclosure. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.

[0034] As shown in FIG. 1 through FIG. 4, this embodiment provides the following technical solution: a real-time adjustable clamping walking device for a flying-walking inspection robot for a transmission line includes a first clamping wheel stand (1), a second clamping wheel stand (2), a slide connecting rod assembly (3), a main push rod assembly (4), a slide rail push rod assembly (5), a support slide rail (6), and an anti-falling mechanism (7). A support beam (19) of the first clamping wheel stand is fixed to the flying-walking inspection robot, the second clamping wheel stand is connected to the side connecting rod assembly and the main push rod assembly, and a bottom of each of the side connecting rod assembly and the main push rod assembly is provided with a boss capable of being installed and sliding on an inner groove of the support slide rail. The support slide rail is also fixedly installed on the flying-walking inspection. The slide rail push rod assembly is installed between the side connecting rod assembly and the main push rod assembly. The anti-falling mechanism is located between the first clamping wheel stand and the second clamping wheel stand. The second clamping wheel stand is attached to the first clamping wheel stand by means of the extension of a main push rod, thus achieving the clamping between the wheel stands. Wheels on the first clamping wheel stand and the second clamping wheel stand cooperate with each other to clamp a cable, and the wheels rotate in the same direction to drive the flying-walking robot to walk along the line.

[0035] Specifically, as shown in FIG. 5, the side connecting rod assembly includes a side rod platform (40), a swinging rod motor (41), a metal motor (42), an adjustable driven swinging rod (43), a driving swinging rod (44), a transmission connecting rod (45), and a slide body (46). An "I-shaped" boss is welded to the bottom of the side rod platform to be in fit with the slide rail, so as to achieve position change. An electromagnet is installed at the bottom of the boss, which is magnetic when energized and non-magnetic when de-energized, so as to control a floating or a fixing state of the boss. The adjustable driven swinging rod and the metal motor are connected into a whole, which is essentially a small electric push rod to achieve the movement relationship change of a connecting rod mechanism through the own length change. One end of the driving swinging rod is connected to the swinging rod motor, the swinging rod motor can drive the driving swinging rod to rotate, and the other end of the driving swinging rod is hinged to the slide body. The slide body can slide in a sliding cavity of the adjustable driven swinging rod, the adjustable driven swinging rod is hinged with the transmission connecting rod, and the transmission connecting rod is hinged to the lower wheel placing platform (30).

[0036] Specifically, as shown in FIG. 6, the support slide rail is internally provided with a slide chute having the same shape as the boss, a slide rail groove of the support slide rail is internally provided with a guide groove for guiding the boss to move. A magnet is installed on the support slide rail. When the electromagnet at the bottom of a boss is energized, the magnets attract each other to relatively fix the boss and the slide rail. Both ends of the slide rail are provided with stop plates to prevent the boss from slipping out. The slide rail push rod assembly (5) is used to connect the side rod platform on a left side to a left end surface at the bottom of the adjustable main rod (50) and connect the side rod platform on a right side to a right end surface of the adjustable main rod. When the main rail-attracting magnet is electrified and attracts the auxiliary rail-attracting magnet, the side connecting rod assembly and the main push rod assembly are controlled to be fixed or floating, and the slide rail push rod assembly drives the side connecting rod assembly (3) and the main push rod assembly (4) to move along the slide chute in the support slide rail (6) through self-extension or retraction.

[0037] Specifically, as shown in FIG. 7 and FIG. 8, according to a walking direction and slope of the flying-walking inspection robot along the line, the power line type is divided into a flat section and an inclined section. The flat section is within a slope ranging from 0°to 10°, and the inclined section is with a slope ranging from 10°to 25°. When the inspection robot walks on the flat section, the main push rod extends to an extreme position, and the entire clamping walking device is as shown in FIG. 8 at this time. When the inspection robot walks on the inclined section, the main push rod retracts, and the pose change of the clamping walking device can be achieved through the length change of the adjustable driven swinging rod and the swinging of the driving swinging rod of the side connecting rod assembly. By changing the length of the main push rod, the positional relationship between the side connecting rod assembly and the main push rod is controlled, and the geometric relationship of rod sets of the clamping walking device is changed. At this time, the entire clamping walking device is shown in FIG. 9. In addition, the lower wheel placing platform (30) is provided with bosses on both sides of each pressure spring, each boss is provided with a main wheel-attracting magnet, which is magnetic when energized and non-magnetic when de-energized. Each wheel in the second clamping wheel platform can be controlled by an electromagnet to lift and drop, so as to improve the phenomenon that one end is tilted and the other end is not clamped, that is, the "middle wheel fulcrum". Further, the number of wheel sets arranged in the first clamping wheel stand and the second clamping wheel stand can be increased or decreased according to the actual situation.

[0038] Specifically, as shown in FIG. 9, the lock body is installed on the first clamping wheel stand, the nested rod is installed on the second clamping wheel stand, and a bottom of the push rod lock cylinder is connected to the nested rod. The nested rod is composed of multi-stage rods by nesting, and a space is reserved in the nested rod for installing a lock rotating motor. The lock rotating motor can drive the push rod lock cylinder to rotate. When the push rod lock cylinder is inserted into a load-bearing lock body and reaches an internal hollow position, the lock rotating motor can rotate to drive the lock cylinder to rotate, and the lock cylinder is aligned with a locking groove at this time. If the lock rotating motor does not rotate, the lock cylinder is always connected into the lock body. When the lock is ready to be unlocked, the lock cylinder is clamped by the wheel stands and then is jacked to the internal hollow position of the lock body, the lock rotating motor rotates, and then the lock cylinder can be pulled out of the lock body along the shape of a lock opening.

[0039] In some embodiments, as shown in FIG. 10, an anti-falling mechanism includes a lock head rod (90), a lock cylinder push rod motor (90), spring buckles (92), and a lock plate (93). The lock head rod is connected to the lock cylinder push rod motor, the lock cylinder push rod motor is fixedly installed above "the flying-walking inspection robot for a transmission line" and can drive the lock head rod to feed. The lock plate is fixedly installed on the support beam (19), the spring buckles are arranged on the lock head rod in a radial direction. When ready to lock, the load-bearing plate is closed, the lock head rod is driven to achieve upward feed, and the spring buckles automatically retract into the lock head rod due to a stress along an inclined plane, and the spring buckles re-extend after the lock head rod enters the lock plate and are kept at a locking state. The locking plate (93) is composed of a locking motor (100), a crank slider mechanism (101) and a load-bearing plate (102). The locking motor can drive the crank slider mechanism to move, thus achieving the opening and closing of the load-bearing plate. When the load-bearing plate is opened, the self-locking is released.

[0040] In some embodiments, as shown in FIG. 11, the lower pressure spring (37) of the second clamping wheel stand is replaced with a side inclined spring platform (80). In an alternative scheme, the lower unfolded rod is connected to the side inclined spring platform, and the side inclined spring platform is connected to the lower wheel placing platform.
