For the sake of general understanding, the structure and operation of the embodiment of the entire climbing robot are described as follows:
the climbing robot, as shown in fig. 1-20, has a preferred structure comprising a main machine 10 in the shape of an elongated frame and a clamping assembly arranged on the main machine 10; in actual operation, the length direction of the main body 10 should be parallel to the length direction of the angle iron a. One surface of the main machine 10 facing the angle steel A is provided with a sliding track, and an electric control sliding block is arranged on the sliding track, so that the main machine 10 can reciprocate along the length direction according to the action of the control unit; and a group of clamping components are fixed on the sliding block one by one. In the particular example configuration shown in fig. 1-6, it can be seen that there are two sets of clamping assemblies, namely, an upper clamping assembly a and a lower clamping assembly b. When the clamping device works, one or both of the upper clamping component a and the lower clamping component b can slide up and down on the sliding track along the length direction of the main machine 10 through the sliding block, so that an inchworm-like action function is realized. When the main body 10 travels to a predetermined point along the angle a and stops, a predetermined operation can be performed by a working part which is previously installed at the head end or other portion of the main body 10. If the working part is a mechanical head with a torque wrench, the tightening action of the assembled mounting screw at the angle steel A can be realized.
On the basis of the above structure, the structure of the clamping assembly is shown in fig. 13-20, and mainly comprises three major parts, namely a clamping jaw 20, an angle adjusting assembly 30 and a lifting assembly 40. Wherein:
clamping jaw 20
The clamping jaw 20 is provided to directly achieve the clamping and loosening functions of the angle iron A. As shown in fig. 7-12, the clamping jaw 20 for the climbing robot of the present invention comprises a fixing base 21 and a clamping end arranged in front of the fixing base 21.
The fixing base 21 is formed by a lower mounting plate 21a, a rear mounting plate 21j and an upper mounting plate 21i, and a guide rod 21k, a push-pull screw rod 21g, a push-pull slider 21f, a push-pull plate 21c, a positioning block 21l, a V-shaped block 21e, a push-pull motor 21h, etc. are installed in a groove cavity of the fixing base 21, as shown in fig. 10-11. The structure of the clamping end comprises two sets of claw rods 22 which are symmetrical to each other, the two sets of claw rods 22 are inserted into the rotary sliding sleeve 23, and the rotary sliding sleeve 23 is fixed on the fixed seat 21 through the vertical hinge seat 23 a. During assembly, the clamping end is fixed relative to the fixed seat 21, and it is required to ensure that the lower shaft end of the vertical push-pull shaft 24 located at the tail end of the claw rod 22 is accurately matched with the orientation groove 21b, that is, the rolling bearing 24a located at the vertical push-pull shaft 24 is accurately in rolling fit with the groove wall of the orientation groove 21 b. Then, the push-pull quick-position guide groove 21d is clamped into the upper shaft end of the vertical push-pull shaft 24, and then the push-pull slider 21f and the push-pull lead screw 21g are sequentially installed. Then, the guide rod 21k is assembled at the upper mounting plate 21i, the upper mounting plate 21i is fixed on the rear mounting plate 21j, and the push-pull motor 21h is mounted on the corresponding plate surface of the rear mounting plate 21j or the tail end of the upper mounting plate 21i through the positioning block 21 l. Finally, the two ends of the V-shaped block 21e are fixed to the head ends of the upper mounting plate 21i and the lower mounting plate 21a, respectively, thereby completing the overall assembly of the clamping ends. In fact, the "straight" shaped guiding groove 21d may also be formed by two sets of horizontal sub-grooves arranged in sequence along the length direction of the push-pull plate 21c, each set of horizontal sub-grooves correspondingly matching with a set of vertical push-pull shafts 24 at the tail end of the claw rod 22, as shown in fig. 10 and 12.
When being directed at the angle steel A of different models, accessible dismantlement is located the grabbing pole 22b of claw pole 22 front end and is changed the grabbing pole 22b of new size to the angle steel A of adaptation current model, the flexibility is obviously higher in the operation. Meanwhile, the replacement part is only the top end position of the claw rod 22, and the sliding rod 22a which is matched with the rotating sliding sleeve 23 and even the sliding plate 21c and other moving parts does not need to be replaced, so that the efficiency and convenience of field replacement are effectively ensured, and multiple purposes are achieved. The guide groove 22c serves the purpose of further ensuring the accuracy of the linear motion of the slide lever 22 a.
Second, the angle adjusting assembly 30
The angle adjustment assembly 30, as shown in fig. 18-20, includes an angle adjustment plate 31, two sets of bottom hinge lugs 32, one set of top hinge lugs 33, one set of screw slider unit formed by the cooperation of an angle adjustment screw 34 and an angle adjustment slider 35, and one set of angle adjustment motor 36.
During actual assembly, firstly, a screw rod sliding block unit is arranged at the upper part of the angle adjusting plate 31, and the angle adjusting motor 36 is correspondingly assembled; meanwhile, a bottom hinge lug 32 is installed at the lower part of the angle adjusting plate 31; at this time, a stable isosceles triangle three-point layout is formed by the two sets of screw slider units and the two sets of bottom hinge lugs 32. The lower part of the fixed seat 21 of the clamping jaw 20 is correspondingly matched with the bottom hinge lug 32, so that the clamping jaw 20 can generate hinge action relative to the bottom hinge lug 32; the upper part of the fixed base 21 extends upwards to form a top hinge lug 33, and the top hinge lug 33 is hinged on an angle adjusting slide block 35 as shown in fig. 16-20.
After the above structure is assembled, when the angle adjustment motor 36 rotates, the angle adjustment screw 34 assembled on the angle adjustment plate 31 through the assembly slot is driven to rotate, and the angle adjustment slider 35 on the angle adjustment screw 34 is driven to move close to and away from the angle steel a. The guiding action of the angle adjusting slider 35 then drives the top hinge lug 33 and thus the whole clamping jaw 20 to swing around the bottom hinge lug 32, thereby achieving the pitch angle adjusting effect of the whole clamping jaw 20.
Third, the lifting assembly 40
As shown in fig. 13-20, the lifting assembly 40 includes a set of vertical bottom plates 41, four sets of guide posts 42, a set of directional screws 43, and a set of lifting motors 44.
During actual assembly, firstly, four groups of guide posts 42 are installed on the angle adjusting plate 31, and then, after the guide posts are in threaded fit with the directional screw rod 43 on the vertical bottom plate 41, the guide posts and the lifting motor 44 on the angle adjusting plate 31 form power fit; at this time, it is sufficient to ensure the insertion and engagement of the guide post 42 with the guide hole or the guide boss on the vertical base plate 41.
After the assembly of the lifting assembly 40 is completed, whenever the lifting motor 44 acts, the orientation screw 43 is driven to rotate, and the slide block on the orientation screw 43, i.e. the vertical bottom plate 41, is driven to act, and the vertical bottom plate 41 acts in a manner of approaching or separating relative to the angle adjustment plate 31 under the guiding action of the guide post 42. When the vertical base plate 41 is fixed to the sliding block of the main body 10, it is obvious that the clamping jaws 20 move toward and away from the main body 10 each time the lifting assembly 40 extends and retracts.
For further description of the action state of the climbing robot of the present invention, the inchworm-type structure is taken as an example here, and the following steps are given in conjunction with fig. 1-6 and fig. 21:
1) fig. 1-2 shows a state diagram of two legs, i.e., two groups of clamping assemblies, clamping the angle steel a at the same time under normal conditions, and it can be seen that the length direction of the main frame 10 is parallel to the length direction of the currently clamped angle steel a;
2) when the main machine 10 needs to go upwards, the lower clamping component b is firstly loosened, and at the moment, due to the action of the gravity of the main machine 10, the main machine 10 has the phenomenon of inclination relative to the angle steel A currently clamped, and the reference is made to fig. 3;
3) the inclinometer on the host 10 acquires the inclination angle of the host 10 relative to the currently clamped angle steel A, and sends a signal to the control unit on the host 10, and the control unit controls the angle adjusting component 30 at the upper clamping component a to act; at this time, the angle adjusting motor 36 starts to operate, so that the clamping jaw 20 at the upper clamping assembly a generates a hinging action relative to the bottom hinging lug 32 through pushing and pulling actions on the top hinging lug 33, and further, a function of adjusting the relative angle between the host 10 and the angle iron a by taking the upper clamping assembly a as a fulcrum is realized until the host 10 is parallel to the currently clamped angle iron a, and at this time, the posture of the host 10 is shown in fig. 4;
4) the lower clamping assembly b generates an upward movement along the main machine 10 through the sliding guide rail and the sliding block, and after the lower clamping assembly b moves upward in place, the angle of the lower clamping assembly b is adjusted through the angle adjusting assembly 30 of the lower clamping assembly b in the same way, so that the angle steel A can be clamped at a proper angle; after the angle of the lower clamping assembly b is adjusted, the lower clamping assembly b can extend to the angle steel A through the lifting assembly 40 and clamp the angle steel A, and the posture of the main body is shown in figure 5;
5) and similarly 2), 3) and 4), when the upper clamping component a is loosened, the host machine 10 inclines relative to the angle steel A currently clamped due to the self-gravity action of the host machine 10; at the moment, the control unit controls the angle adjusting assembly 30 at the lower clamping assembly b to act, so that the relative angle between the main machine 10 and the angle steel A is adjusted by taking the lower clamping assembly b as a fulcrum until the main machine 10 is parallel to the currently clamped angle steel A;
6) the main machine 10 moves upwards relative to the lower clamping component b, and when the main machine 10 moves upwards to a proper position, the angle of the upper clamping component a is adjusted through the angle adjusting component 30 of the upper clamping component a; after the angle of the upper clamping component a is adjusted, the lifting component 40 extends to the angle steel a and clamps the angle steel a, and finally the main machine 10 is restored to the state shown in fig. 6, in which the main machine 10 is parallel to the angle steel a, and the state shown in fig. 6 is the state after the upward step in the state shown in fig. 2, so that the one-wheel walking control action is completed.
When the main machine 10 needs to carry the working part to go up continuously, the steps are taken as a cycle, and the cycle is repeated. Otherwise, if the host 10 needs to go down, the same process can be performed. Similarly, when the host 10 needs to avoid the obstacle B, it is only necessary to retract the corresponding clamping assembly to the lowest position.
For the working part, it may be a torque wrench, a camera or even a welding head, etc., as appropriate depending on the field conditions. As a functional element for performing precise operation, the working portion may be mounted at any position on the main body 10, and may even form an integral structure with the main body 10 or form a structure convenient to mount and dismount with respect to the main body, which is not described herein again.
Of course, the above is one specific embodiment of the present invention. In actual operation, equivalent replacement of each power source is performed, for example, a driving cylinder or even a gear rack mode is adopted to replace the rotation driving action of each motor, the number of clamping assemblies is increased, or the arrangement mode of the clamping assemblies is changed, or even a plurality of groups of main machines 10 of the climbing robot can be hinged end to form a robot structure which is more insect-like, and the like; such conventional variations in structure, which are within the spirit of the invention and are known to the person skilled in the art, are considered to fall within the scope of the invention as it is equally or similarly designed.
