Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Example 1
Referring to fig. 1 to 5, an embodiment of the present invention discloses a hook 100, wherein the disclosed hook 100 includes a hook portion 110 and a base portion 120; the hook part 110 is rotatably arranged on the base part 120 through a hinge 121 such as a pin or a rivet, and the base part 120 is provided with a hole 123 for passing the rope 410, so that the rope 410 can be connected with the bottom end of the hook part 110 after passing through the base part 120 through the hole 123; the hook 110 is rotated in a direction of a back side of the hook 110 to a first inclined state by its own weight, and the hook 110 is rotated in a direction of an opening of the hook 110 to a second vertical state by a tensile force of the rope 410.
In the process of getting on the line, after the hook 100 moves upwards to be separated from the conducting wire or the contact wire, the line winding and unwinding mechanism 400 continues unwinding, so that the hook part 110 loses the tensile force of the rope 410 and rotates to the inclined first state in the direction of the back side of the hook part 110 under the action of the gravity of the hook part, namely, the hook part 110 deviates from the conducting wire or the contact wire to avoid the obstacle on the line, and further, the obstacle crossing robot on the line can carry out obstacle crossing walking on the line along the conducting wire or the contact wire.
In the process of off-line, the take-up and pay-off device takes up the wire to enable the hook part 110 to overcome self gravity and rotate to a vertical second state towards the opening of the hook part 110 under the action of the pulling force of the rope 410, so that the hook part 110 returns to the upper part of the guide line or the contact line, and the hook 100 is ensured to be in contact suspension with the lead or the contact line again to be used as a stress point when moving downwards so as to carry out off-line; therefore, compared with the upper and lower line lifting hook structure adopted by the existing robot, the invention can be well applied to the robot with the function of walking on the line over obstacles.
It is easy to understand that, in order to ensure that the hook portion 110 can rotate to the inclined first state toward the back side of the hook portion 110 under the action of its own gravity after losing the pulling force of the rope 410, when the hook portion 110 is in the vertical state, the center of gravity of the hook portion 110 needs to be located on the side of the back side of the hook portion of the hinge member 121, and as shown in fig. 1 generally, a weight member 111 may be disposed on the back side of the hook portion 110; the back side of the hook portion 110 refers to a portion of the hook portion 110 that faces the suspension opening.
Preferably, the base portion 120 may be a cylindrical structural member, and the hook portion 110 is rotatably disposed at the top end of the base portion 120 by a hinge 121; therefore, the cylindrical structural design is beneficial to the insertion fit of the base part 120 and the tube cavity of the barrel body 300 which is described below, and the base part 120 can smoothly rotate relative to the tube cavity of the barrel body 300 under the action of the correction structure.
Meanwhile, the base part 120 may be provided with a correction structure, so that when the base part 120 is inserted into the cylinder 300, the correction structure of the base part 120 and the correction structure of the cylinder 300 are matched with each other to realize automatic rotation correction of the hook part 110, that is, the opening of the hook part 110 faces the direction of the conducting wire or the contact wire, and thus when the hook part 110 rotates to the vertical second state, it is ensured that the hook part 110 can be suspended above the conducting wire or the contact wire, and re-suspension contact with the conducting wire or the contact wire can be completed after the hook part 110 descends.
Specifically, the correction structure may be a second magnetic element disposed on the base 120, and the second magnetic element forms an opposite "N" pole magnetic region 1201 and an "S" pole magnetic region 1202 on an outer sidewall of the base 120; as shown in fig. 5, in the process of inserting the base part 120 into the cylinder 300 described below, the second magnetic element forms the "N" pole magnetic region 1201 and the "S" pole magnetic region 1202 facing each other on the outer side wall of the base part 120, and the "N" pole magnetic region 3001 and the "S" pole magnetic region 3002 facing each other on the first magnetic element provided on the inner side wall of the cylinder 300 generate a magnetic force action, thereby achieving automatic correction and adjustment of the opening orientation of the hook part 110 by the magnetic force action.
For example, when the "N" pole magnetic region 1201 of the second magnetic element and the "N" pole magnetic region 3001 of the first magnetic element, the "S" pole magnetic region 1202 of the second magnetic element, and the "S" pole magnetic region 3002 of the first magnetic element are in at least partially opposing positions, the base 120, during insertion into the lumen of the barrel 300, rotates to a position where the "N" pole magnetic region 1201 of the second magnetic element and the "S" pole magnetic region 3002 of the first magnetic element, the "S" pole magnetic region 1202 of the second magnetic element, and the "N" pole magnetic region 3001 of the first magnetic element are in opposing positions under the action of like-polarity opposing magnetic forces, and maintains this state under the action of opposite-polarity opposing magnetic forces, thereby achieving automatic rotational correction of the orientation of the opening of the hook 110, i.e., the opening of the hook 110 is oriented in the direction of the conductive wire or the contact wire.
In the hook 100 disclosed in this embodiment, a third magnetic element 112 may be further disposed on the hook portion 110, and the third magnetic element 112 forms an "N" pole magnetic region and an "S" pole magnetic region on the left side surface and the right side surface of the hook portion 110, respectively; that is, the third magnetic element 112 forms an "N" pole magnetic region on the left side surface of the hook portion 110 and an "S" pole magnetic region on the right side surface of the hook portion 110; alternatively, the third magnetic element 112 has an "S" pole magnetic region on the left side surface of the hook 110 and an "N" pole magnetic region on the right side surface of the hook 110.
An N-pole magnetic area and an S-pole magnetic area are respectively formed on the left side surface and the right side surface of the hook part 110 through the third magnetic element 112, so that when the hook 100 needs to be taken off from the line through an operating rod after the hook is off line, an operator can directly put the operating rod on a lead or a contact line and slide to the hanging position of the hook part 110 along the line, so that the operating rod is in contact with the side surface of the hook part 110, the hook part 110 and the operating rod are adsorbed together through the magnetic force action, and the hook 100 can be conveniently and quickly taken off from the line; therefore, the problem that the operation difficulty of taking the hook 100 off the line is large due to the fact that the existing hook 100 needs to be aligned and lifted by an operating rod can be solved.
Especially in the application scenario where at least two hangers 100 are provided for lifting, the orientations of the "N" pole magnetic region and the "S" pole magnetic region formed by the third magnetic element 112 of each hanger 100 are the same; that is, the magnetic regions of "N" poles are all located on the left side surface of the hook portion 110, and the magnetic regions of "S" poles are all located on the right side surface of the hook portion 110; alternatively, the "N" pole magnetic regions are all located on the right side of the hook 110, and the "S" pole magnetic regions are all located on the left side of the hook 110.
Therefore, when the hanging directions of two adjacent hooks 100 are consistent, the polarities of the magnetic regions on two opposite side surfaces are opposite, so that the operating rod can push the hooks 100 to be adsorbed together through the magnetic action of opposite attraction, the hooks 100 adsorbed together can be simultaneously taken down from the line through one-time operation, the operation times are reduced, and the operation is more convenient and faster; when the hanging directions of two adjacent hooks 100 are opposite, the polarities of the magnetic regions on two opposite sides are the same, so that the two adjacent hooks 100 can be prevented from being adsorbed together through the action of the magnetic force of the same polarity repelling each other, and the problem that the operation difficulty of taking the hooks 100 off the line is increased due to the formation of a closed structure is solved.
Specifically, the number of the third magnetic elements 112 is three, and the third magnetic elements are arranged at intervals along the extending direction of the hook portion 110, so that the magnetic area of the side surface of the hook portion 110 is increased; meanwhile, the hook 110 is provided with a through hole penetrating through the left and right side surfaces, the third magnetic element 112 is disposed in the through hole and is in interference fit with the through hole, so that the third magnetic element 112 is mounted and fixed, and one end magnetic pole of the third magnetic element 112 is located at one end port of the through hole and the other end magnetic pole is located at the other end port of the through hole, so as to form a corresponding magnetic pole area. Of course, the number and the arrangement manner of the third magnetic elements 112 can be adjusted adaptively according to the actual design and use conditions.
Preferably, a rolling member 113 such as a roller or a ball may be further disposed on the suspension contact surface of the hook portion 110, so that the friction between the suspension contact surface of the hook portion 110 and the conductive wire or the contact wire may be reduced by the rolling member 113, and the hook 100 may be ensured to move smoothly along the conductive wire or the contact wire.
Example 2

When the wire is fed, the take-up and pay-off mechanism 400 takes off the wire, so that the base part 120 of the hook 100 can be separated from the lifting mechanism, and the hook 100 is hung on the wire or the contact wire through the hook part 110; then, the wire winding and unwinding mechanism 400 winds up, so that the device body 500 rises to a required height, the travelling mechanism of the device body 500 acts and hangs on a lead or a contact line, at this time, the base part 120 of the hook 100 is in a matching state with the lifting mechanism, the lifting mechanism is matched with the wire winding and unwinding mechanism 400 to wind a wire, so that the base part 120 can be pushed to move upwards for a certain distance, the hook part 110 is separated from the lead or the contact line upwards, the wire winding and unwinding mechanism 400 continues to wind a certain distance, the hook part 110 loses the tensile force of the rope 410 and rotates to the direction of the back side of the hook part 110 under the action of the self gravity to reach an inclined first state, namely, the hook part 110 deviates from the lead or the contact line and can avoid obstacles on the line, and the device body 500 can smoothly walk over the obstacles on the line.
When the cable is off line, the take-up and pay-off mechanism 400 takes up the cable for a certain distance, so that the hook part 110 overcomes the self gravity and rotates to a vertical second state under the action of the pulling force of the cable 410, the hook part 110 returns to the position above the guide line or the contact line, the take-up and pay-off mechanism 400 continues to take up the cable for a certain distance, and the base part 120 moves downwards together with the descending movement of the lifting mechanism, so that the hook part 110 can be ensured to be contacted with the lead or the contact line again to be used as a stress point; then, the traveling mechanism of the device body 500 is disengaged from the wire or contact wire, and the take-up and pay-off mechanism 400 pays off the wire, so that the device body 500 is lowered to the ground.
The lifting mechanism disclosed in this embodiment may be an electric lifting mechanism, a pneumatic lifting mechanism, a hydraulic lifting mechanism or an elastic lifting mechanism; after the device body 500 is hung on a conducting wire or a contact wire, the device body is matched with the take-up and pay-off mechanism 400 to pay off, and the lifting mechanism controls the ascending movement of the base part 120, so that the upward separation of the hook part 110 and the conducting wire or the contact wire is realized; when the device body 500 is taken off the line, the take-up and pay-off mechanism 400 is used for taking up the line, and the lifting mechanism controls the descending movement of the base part 120, so that the hook part 110 is downwards contacted and suspended with a conducting wire or a contact wire.
The electric lifting mechanism is a mechanism which uses electric energy as a power source to realize lifting movement, such as an electric screw lifting device or an electric rack-and-pinion lifting device, so that the lifting movement of the electric lifting mechanism drives the hook 100 to perform corresponding lifting movement; when the device is used, the walking power supply carried by the device main body 500 can be used for simultaneously providing electric energy required by the action for the electric lifting device, and certainly, the power supply can be independently arranged for supplying power for the electric lifting device; the pneumatic lifting mechanism can select the existing pneumatic lifting rod, and the hydraulic lifting mechanism can select the existing hydraulic lifting rod and the like.
The elastic lifting mechanism is a mechanism which realizes lifting movement by utilizing the elastic compression deformation and elastic recovery deformation processes of elastic elements 310 such as springs or elastic sheets; when the hook part 110 is in a vertical second state, the rope 410 is wound to pull the hook part 110, so that the base part 120 can press the elastic element 310 to contract, and therefore the downward movement is realized, the rope 410 is wound to release the hook part 110, so that the pressed elastic element 310 expands and recovers, and therefore the base part 120 is pushed to realize the upward movement; compared with an electric lifting mechanism, the elastic lifting mechanism can effectively reduce the power consumption of the device main body 500, is beneficial to improving the cruising ability of the device main body 500, avoids carrying an additional power supply, and is beneficial to reducing the weight of the device main body 500.
Therefore, the lifting mechanism is preferably an elastic lifting mechanism; as shown in fig. 4 and 5 in particular, the elastic lifting mechanism may include a cylinder 300 and an elastic element 310; the top surface of the cylinder 300 is an open end 301 for the insertion and matching of the base 120 and the tube cavity of the cylinder 300, and the bottom surface of the cylinder 300 is a closed end and is provided with a through hole 302 for the rope 410 to pass through; the elastic element 310 is arranged in the tube cavity of the barrel body 300; under the action of the take-up and pay-off mechanism 400 to take up and pay off the rope 410, the base 120 has a lifting state of squeezing and relaxing the elastic member 310.
Meanwhile, the tube cavities of the base 120 and the cylinder 300 can be designed into cylindrical structures, and the diameter of the tube cavity of the cylinder 300 is larger than that of the base 120, so that the base 120 and the cylinder 300 can be conveniently matched in an inserting manner, and the base 120 can smoothly rotate relative to the tube cavity of the cylinder 300 under the action of a correction structure, so that automatic rotation correction of the hook is realized; of course, according to the actual design, the lumens of the base 120 and the cylinder 300 may be designed to be regular polygons, but in order to ensure that the base 120 can be smoothly inserted into and rotationally fitted with the lumen of the cylinder 300, the diameter of the inscribed circle of the lumens needs to be larger than the diameter of the circumscribed circle of the base 120.
It is easy to understand that, in order to make the base 120 more easily perform the inserting and fitting with the barrel 300, the open end 301 of the barrel 300 may be designed to be a trumpet-shaped flaring structure, so that during the inserting and fitting process, the inserting and fitting of the base 120 and the tube cavity may be guided by the trumpet-shaped flaring structure, which is beneficial to the alignment of the inserting and fitting of the base 120 and the barrel 300.
In the above solution, since the rope 410 has a degree of freedom and the base 120 may rotate relative to the cylinder 300, during engineering application, when the hook 110 rotates to the inclined first state, the opening of the hook 110 may deflect and even face away from the wire or the contact line, and then after the hook 110 rotates to the vertical second state, the hook 110 moves downward and cannot be re-suspended on the wire or the contact line.
In view of the above problem, in the elastic lifting mechanism disclosed in this embodiment, the barrel 300 and the base 120 may be provided with a calibration structure which is matched with each other, so that when the base 120 is matched with the lumen of the barrel 300 in an inserting manner, the base 120 can rotate relative to the barrel 300 under the action of the calibration structure, so as to realize automatic rotation calibration of the opening orientation of the hook portion 110, that is, the opening of the hook portion 110 faces the direction of the conducting wire or the contact wire, and further, after the hook portion 110 rotates to the vertical second state, the hook portion 110 can move downward and smoothly re-hang on the conducting wire or the contact wire.
As an embodiment of the correcting structure, as shown in fig. 5, the correcting structure may include a first magnetic element provided to the cylinder 300, and a second magnetic element provided to the base 120; the first magnetic element forms an opposite N-pole magnetic region 3001 and an opposite S-pole magnetic region 3002 on the inner side wall of the cylinder 300, and the second magnetic element forms an opposite N-pole magnetic region 1201 and an opposite S-pole magnetic region 1202 on the outer side wall of the base 120, so that the base 120 can automatically rotate and correct through the magnetic action between the first magnetic element and the second magnetic element.
As other possible embodiments of the calibration structure, the calibration structure may also include a guide portion disposed on the inner sidewall of the lumen of the cylinder 300, and a sliding portion disposed on the outer sidewall of the base portion 120; the guide part extends along the spiral direction, the sliding part can be in sliding fit with the guide part, and the guide part is provided with a positioning groove in positioning fit with the sliding part.
When the base part 120 is inserted into the barrel 300, the base part 120 can perform spiral rotation through the sliding movement of the sliding part along the guide surface, so that the automatic rotation correction of the opening orientation of the hook part 110 is realized, and when the sliding part slides to the position of the positioning groove, the continuous rotation of the base part 120 is limited through the positioning matching of the sliding part and the positioning groove, and further the fixed keeping of the opening orientation of the hook part 110 is completed.
Preferably, as shown in fig. 3, notches 304 may be respectively formed at two opposite sides of the opening end 301 of the cylinder 300, which are located in the rotation direction of the hook 110, so that the hook 110 may be placed in the notch 304 when rotating to the inclined first state, and the notch 304 may limit the inclined hook 110, thereby better preventing the opening of the hook 110 from deflecting due to the rotation of the base 120 relative to the cylinder 300, and further preventing the hook 110 from being unable to be re-suspended on a wire or a contact wire after rotating to the vertical second state.
In this embodiment, as shown in fig. 1, 2 and 5, the base 120 of the hook 100 may be provided with a limiting portion 122; correspondingly, a thimble structure 320 matched with the limiting part 122 is arranged on the inner side wall of the cylinder 300, and the thimble structure 320 has an extending state and a retracting state; when the thimble structure 320 is in the extended state, the thimble structure 320 can abut against the limiting portion 122 for limiting the base 120; when the thimble structure 320 is in the retracted state, the thimble structure 320 may release the position-limiting portion 122 for releasing the position limitation of the base 120.
When the base part 120 is inserted into the lumen of the cylinder 300, the thimble structure 320 is in an extended state, so that the thimble structure 320 can abut against the limiting part 122, thereby limiting the base part 120, and in the process that the take-up and pay-off mechanism 400 takes up the rope 410 to pull the hook part 110 to rotate to the vertical second state, because the thimble structure 320 limits the base part 120, the problem that the vertical height of the hook part 110 is reduced due to the fact that the base part 120 extrudes the elastic element 310 to move in the rotating process of the hook part 110 can be prevented, and further, the hook part 110 which rotates to the vertical state can be located above a lead or a contact line.
After the hook part 110 rotates to the vertical second state, the take-up and pay-off mechanism 400 continues to take up the rope 410, and at this time, the thimble structure 320 retracts to be separated from the limiting part 122, so that the thimble structure 320 loosens the limiting part 122, the limiting on the base part 120 is released, so that the base part can press the elastic element 310 to move under the pulling force of the rope 410, and the hook part 110 moves downwards to be in suspension contact with the conducting wire or the contact wire.
Therefore, through the design of the thimble structure 320 and the limiting portion 122, the rotation of the hook portion 110 to the vertical state and the extrusion of the elastic element 310 by the base portion 120 are sequentially performed separately, so that compared with a mode that the rotation of the hook portion 110 to the vertical state and the extrusion of the elastic element 310 by the base portion 120 are performed simultaneously, the problem that the height of the hook portion 110 after the rotation to the vertical state is reduced to affect the suspension matching between the hook portion 110 and a lead or a contact line can be effectively avoided.
It is easy to understand that the limiting portion 122 may be an annular rib structure disposed along the circumferential direction of the base portion 120, or an annular groove structure disposed along the circumferential direction of the base portion 120; the thimble structure 320 may be a pogo-thimble structure, so that the pogo-thimble structure can be automatically retracted along with the increase of the pressing force of the limiting portion, and of course, the thimble structure may also be a thimble structure controlled by another telescopic mechanism.
In the device with lifting function disclosed in the embodiment of the present invention, as shown in fig. 3, the device main body 500 is provided with two take-up and pay-off mechanisms 400, and the front side wall and the rear side wall of the device main body 500 are respectively provided with corresponding lifting mechanisms, so that the ropes 410 respectively led out from the two take-up and pay-off mechanisms 400 are respectively connected with two corresponding hooks 100 after passing through the corresponding lifting mechanisms.
The hook parts 110 of the two hooks 100 are provided with third magnetic elements 112, the third magnetic elements 112 form magnetic regions of "N" poles on the left side surfaces of the hook parts 110, and the magnetic regions of "S" poles are formed on the right side surfaces of the hook parts 110; meanwhile, the suspension contact surfaces of the two hook portions 110 are provided with rolling members 113, so that the friction between the suspension contact surfaces of the hook portions 110 and a wire or a contact line can be reduced by the rolling members 113.
When the hanging positions of the two hooks 100 are too far away or too close to each other, the hooks 100 can smoothly move along a conducting wire or a contact wire in an adaptive manner under the action of the tension of the rope 410, so that the rope 410 is ensured to be basically in a vertical state in the hoisting process, the problem that the rope 410 inclines outwards or inwards in the hoisting process due to the fact that the hanging positions of the two hooks 100 are too far away or too close to each other is avoided, and the hoisting stability of the device main body 500 is further facilitated; in addition, in the process of taking the hook 100 off the line, the operation rod is convenient to push the hook 100 to move for magnetic adsorption.
It should be noted that the apparatus main body 500 in this embodiment includes, but is not limited to, apparatuses or devices applied to a wire or a contact wire, such as an online traveling apparatus, an online inspection robot, or an online maintenance robot, and may also include apparatuses or devices applied to a suspended track, such as a suspended track traveling apparatus, a suspended track inspection robot, or a suspended track maintenance robot, and the present invention does not limit the type and application scenarios of the apparatus main body 500.
