The invention provides a beam body detection track, which comprises a suspension traction piece 1, a driving rope 2 and a plurality of track units 3 distributed side by side. In this beam body detection track, all track units 3 are distributed side by side along the same line, including but not limited to along the same straight line or along the same curved surface.
For two adjacent track units 3, the adjacent upper edges of the two track units 3 are pivotally hinged so that the adjacent lower edges of the two track units 3 are separated and brought closer together in a side-by-side distribution direction. Wherein, two adjacent track units 3 are in a fixed-axis hinge relation, and the hinge part of the two track units is visible to be a joint 31.
The number of track units 3 may be two or more for all track units 3. When the number of the track units 3 is 2, any one of the track units 3 is connected with the suspension traction member 1, for example, two track units 3 are connected to the same suspension traction member 1, or two track units 3 are respectively connected to one suspension traction member 1. When two track units 3 are connected to the same suspension traction member 1, the suspension traction member 1 generally adopts a flexible structure including, but not limited to, ropes, chains, and the like. The suspension traction member 1 may be sequentially threaded through the two rail units 3, for example, sequentially threaded through and straddled around pulley structures of the two rail units 3. When the number of the rail units 3 is 2 or more, the suspension traction members 1 are connected to the rail units 3 located at both ends in the side-by-side distribution direction, and in short, the suspension traction members 1 pull all the rail units 3 upward at both ends in the side-by-side distribution direction of all the rail units 3. In the latter case, the suspension traction member 1 may be a flexible rope, a chain, or the like, or may be a rigid rod-like structure.
When the beam body is used for detecting the track, all the track units 3 can be pulled upwards by the suspension traction piece 1, so that the suspension installation of all the track units 3 below the beam body 01 to be detected is realized. For example, when the beam body detection rail is used for detecting a bridge, all the rail units 3 are located below the bridge and distributed along the width direction of the bridge, and the suspension traction members 1 are pulled upward from both ends of the bridge in the width direction, so that all the rail units 3 are suspended in the mid-air. At the same time, the side-by-side distribution trajectory of all the track units 3 is adjusted by adjusting the length of the drive ropes 2 defined between all the track units 3.
For example, when the driving rope 2 has not applied a force to all the track units 3 or the applied force is small, the length of the driving rope 2 defined between all the track units 3 is large, and then the track units 3 positioned in the middle of the side-by-side distribution direction are suspended downward, so that the side-by-side distribution track of all the track units 3 takes a shape in which the middle is bent downward and both ends are tilted upward. For convenience of description, this state of the entire track units 3 will be referred to as a deployed state hereinafter.
For another example, when the driving rope 2 applies a large force to all the track units 3, and the length of the driving rope 2 defined between all the track units 3 is shortened, the driving rope 2 pulls all the track units 3 to tighten so that the parallel distribution trajectories of all the track units 3 approach a straight line. For convenience of description, this state of the entire track unit 3 will be referred to as a tightened state hereinafter.
Obviously, when adjusting from the unfolded state to the folded state, it is necessary to stretch both ends of the driving rope 2, so that the length of the driving rope 2 defined between all the track units 3 is shortened; when the device is adjusted from the contracted state to the expanded state, both ends of the drive rope 2 need to be loosened, and the length of the drive rope 2 limited between all the track units 3 needs to be increased. When the length of the driving rope 2 defined between all the rail units 3 is reduced to the minimum length, all the rail units 3 are distributed along a straight line, and the adjacent end surfaces of the two adjacent rail units 3 are flatly attached, in other words, the parallel distribution tracks of all the rail units 3 are in a straight line.
In summary, the beam body detection track provided by the invention can be arranged below the beam body 01 to be detected through the suspension traction piece 1, so that the side-by-side distribution track of all the track units 3 is naturally bent under the action of dead weight, and the relative position relation of all the track units 3 can be adjusted by combining the driving rope 2, thereby adjusting the side-by-side distribution track of all the track units 3, including but not limited to stretching the originally bent side-by-side distribution track to be flat. It can be seen that the beam body detection track utilizes the suspension traction piece 1 and the driving rope 2 to jointly adjust the side-by-side distribution track of all the track units 3, so that the side-by-side distribution track conforms to the shape of the beam body 01 to be detected, and the movement of relevant detection equipment along the beam body detection track is met.
The beam body detection track provided by the invention is further described below with reference to the accompanying drawings and embodiments.
In the beam body detection track, any one of the track units 3 may be configured as a truss structure, that is, any one of the track units 3 is formed by connecting a plurality of rod members having different directions. For example, one track unit 3 may comprise a plurality of axial bars, a plurality of transverse bars, a plurality of vertical bars and a plurality of diagonal bars; all axial bars are parallel and not in the same plane; all the transverse rod pieces and all the vertical rod pieces are connected to the axial rod pieces at an angle perpendicular to the axial rod pieces, so that the rod body peripheral sides of all the axial rod pieces are surrounded; all the diagonal rods are connected between columnar frames surrounded by the axial rods, the transverse rods and the vertical rods.
For the truss structure of the track unit 3, the beam body detection track can be used as a guide rail structure for a moving platform to slide along the track through a track body 11 arranged on the side surface of the track unit 3. In other words, the beam body detection rail with the above structural characteristics needs to be matched with the above moving platform, and only when all rail units 3 are distributed side by side along the same line, all rail bodies 11 of all rail units 3 can be coaxially spliced to form a guide rail structure for the moving platform to slide along the rail.
Wherein the shape of the cross-section outer frame of the rail unit 3 depends on the relative positional relationship of all the axial bars. For example, one track unit 3 may include four axial bars, and axial end faces of the four axial bars are located at four vertex corners of a rectangle, respectively; one rail unit 3 may also comprise three axial bars, and the axial end faces of the three axial bars are respectively located at three apex angles of the triangle, two of the three axial bars being located above and the other being located below, so that the axial end faces of the axial bars are in a triangle with apex angles facing downward.
Further, the aforementioned all-rail units 3 may include the intermediate unit body 301 and the side end unit bodies 302 located at both sides of the intermediate unit body 301 according to the relative positional relationship of the all-rail units 3 in the side-by-side distribution direction. For example, when the number of all the track units 3 is three, one middle unit body 301 and two side end unit bodies 302 are included; when the number of all the track units 3 is four, two middle unit bodies 301 and two side unit bodies 302 are included; similarly, the N track units 3 include two side end unit bodies 302 and N-2 intermediate unit bodies 301.
The side unit body 302 extends linearly along the side-by-side distribution direction of all the track units 3; the intermediate unit 301 extends in a straight line or in an arc along the side-by-side distribution direction of all the track units 3.
Meanwhile, in connection with the cross-sectional frame shape of the rail unit 3, for the side end unit body 302, it may include two structural shapes: the cross-section outer frame of the side end unit body 302 is rectangular, and the cross-section outer frame of the side end unit body 302 is triangular with downward vertex angle.
For the intermediate unit 301, it may include four structural shapes: the side-by-side distribution direction of the middle unit body 301 is a triangle with a straight line extension and a cross section outer frame being a rectangle, the side-by-side distribution direction of the middle unit body 301 is a straight line extension and a cross section outer frame being a triangle with a downward apex angle, the side-by-side distribution direction of the middle unit body 301 is an arc extension and the cross section outer frame is a rectangle, the side-by-side distribution direction of the middle unit body 301 is an arc extension and the cross section outer frame is a triangle with a downward apex angle.
As for the adjacent upper edges of the adjacent two rail units 3, a fixed axis hinge can be achieved by the male hinge support 5 and the female hinge support 6. For example, when all the track units 3 include one middle unit body 301 and two side end unit bodies 302, the two upper edges of the middle unit body 301 along the side-by-side distribution direction may be provided with male hinge supports 5, and the inner upper edge of any side end unit body 302 along the side-by-side distribution direction may be provided with female hinge supports 6. When all the track units 3 include a plurality of intermediate unit bodies 301 and two side end unit bodies 302, the male hinge support 5 and the female hinge support 6 are respectively provided on two upper edges of any one intermediate unit body 301 along the side-by-side distribution direction, one of the two side end unit bodies 302 is provided with the male hinge support 5, and the other is provided with the female hinge support 6.
When the male hinge support 5 is hinged to the female hinge support 6, the hinge shaft 51 of the male hinge support 5 may be inserted into the mounting hole of the female hinge support 6, so as to realize the fixed-axis rotation of the female hinge support 6 around the hinge shaft 51.
When the operator detects the rail using the beam, he can manually or by means of a power plant pull the ends of the drive ropes 2, thereby adjusting the length of the drive ropes 2 defined between all rail units 3.
Illustratively, the track unit 3 is fixed with a hoist 13; one or both ends of the driving rope 2 are connected to the aforementioned winding machine 13. When the hoist 13 is operated, the driving rope 2 is wound around the drum structure of the hoist 13, thereby tightening the driving rope 2, or the driving rope 2 wound around the drum of the hoist 13 is unwound, thereby properly releasing the driving rope 2.
As for the specific connection of the hoisting machine 13 with the drive rope 2, four reference examples are provided below.
As shown in fig. 12, the beam body detection rail includes a hoist 13 and a driving rope 2. For convenience of description, the outermost two track units 3 in the side-by-side distribution direction will be referred to as a first track unit 3 and a second track unit 3, respectively, hereinafter. In this example, the hoist 13 is fixed to the first rail unit 3; one end of the driving rope 2 is fixed to the second rail unit 3, and the other end sequentially winds around the driving fixed pulleys 4 of all the rail units 3 and finally pulls to the hoist 13.
As shown in fig. 13, the beam body detection rail includes two hoists 13 and one driving rope 2. In this example, two winches 13 are fixed to the first rail unit 3 and the second rail unit 3, respectively; the two ends of the driving rope 2 are respectively connected with the two winders 13, and the driving fixed pulleys 4 of all the track units 3 are sequentially wound on the middle part of the driving rope 2 along the side-by-side distribution direction.
As shown in fig. 14, the beam body detection rail includes two hoists 13 and two driving ropes 2. In this example, two winches 13 are fixed to the first rail unit 3 and the second rail unit 3, respectively; one end of the first driving rope 2 and one end of the second driving rope 2 are respectively connected with the same track unit 3 positioned at the middle of the side-by-side distribution direction, and the other end of the first driving rope 2 and the other end of the second driving rope 2 are respectively connected with the windlass 13 at the same side. Of course, the middle part of any one of the driving ropes 2 is sequentially wound with the driving fixed pulley 4 between the driving rope and the same-side winding machine 13.
Wherein, the same side refers to another description object which takes the description object as a base point and is closest to the description object in the side-by-side distribution direction. For example, as above, for the first drive rope 2, one of the two winches 13 that is closer to the first drive rope 2 is regarded as the same side winch 13; in contrast, the other winch 13 of the two winches 13 is closer to the second drive rope 2.
As shown in fig. 15 and 16, the beam body detection rail includes four hoists 13 and two driving ropes 2. In this example, two windlass 13 are provided on opposite sides of the first track unit 3, respectively, and two windlass 13 are also provided on opposite sides of the second track unit 3; meanwhile, two adjacent track units 3 positioned in the middle of the side-by-side distribution direction are respectively provided with a reversing fixed pulley 14 at the bottom of each track unit, the middle of the first driving rope 2 is wound on one reversing fixed pulley 14, two ends of the first driving rope 2 are respectively connected with two windlass 13 positioned on the same side, and two ends of the second driving rope 2 are respectively connected with two windlass 13 positioned on the same side. Of course, any one of the drive ropes 2 is wound around the drive fixed sheave 4 with the winding machine 13 on the same side in sequence.
Wherein, when the installation height of the hoist 13 is greater than the installation height of the driving fixed pulley 4 adjacent thereto, the driving rope 2 should be wound from the bottom of the driving fixed pulley 4 and pulled up to the hoist 13; when the installation height of the hoist 13 is smaller than the installation height of the driving fixed sheave 4 adjacent thereto, the driving rope 2 should be wound from the top of the aforementioned driving fixed sheave 4 and pulled down to the hoist 13. Considering that the driving ropes 2 are used to adjust the distance between the adjacent lower edges of the adjacent track units 3, in order to more effectively adjust the relative positions of the adjacent track units 3 by the driving ropes 2, the driving fixed sheave 4 is generally disposed at the bottom surface of the track units 3, which results in that the installation height of the hoist 13 is generally greater than the installation height of the driving fixed sheave 4.
In order to improve the connection of the drive rope 2 to the drive fixed pulleys 4, the drive fixed pulleys 4 may be arranged in groups. For example, any one of the driving fixed pulleys 4 includes two grooves juxtaposed along the rotation axis, and the rotation axis of the driving fixed pulley extends horizontally and is perpendicular to the side-by-side distribution direction. With this construction of the drive fixed pulleys 4, the drive ropes 2 can be wound in different roping between adjacent drive fixed pulleys 4 of adjacent two track units 3.
Obviously, for the two rail units 3 located at the outermost side in the side-by-side distribution direction, the outer side of the rail unit 3 is no longer adjacent to the other rail units 3, and therefore the drive rope 2 can be directly wound under or over the drive fixed pulley 4 of the rail unit 3.
As for the roping of the drive ropes 2 between adjacent drive fixed pulleys 4 of adjacent two track units 3, two specific examples are provided below.
The first rope winding mode belongs to the winding rope in the shape of Chinese character 'Hui'. As shown in fig. 7, one of the driving fixed pulleys 4 has a groove I-I and a groove I-II, and the other driving fixed pulley 4 has a groove II-I and a groove II-II, as seen in the adjacent driving fixed pulleys 4 of the adjacent two rail units 3. Wherein the wheel groove I-I and the wheel groove II-I are positioned on the same vertical plane; the wheel groove I-II and the wheel groove II-II are positioned on the same vertical plane. Based on the foregoing structure, the drive rope 2 can be led from the lower tread of the wheel groove I-I, wound around one half circumference of the wheel groove II-I after being wound around the lower tread of the wheel groove II-I, then wound around the upper tread of the wheel groove I-II from the upper tread of the wheel groove II-I, and further wound around the lower tread of the wheel groove II-II after winding around one half circumference of the wheel groove I-II, and finally led out from the lower tread of the wheel groove II-II.
The second rope winding mode belongs to the 8-shaped rope winding mode. As shown in fig. 8, also in the adjacent driving fixed pulleys 4 of the adjacent two track units 3, one driving fixed pulley 4 has a groove I-I and a groove I-II, and the other driving fixed pulley 4 has a groove II-I and a groove II-II. The wheel groove I-I and the wheel groove II-I are positioned on the same vertical plane; the wheel groove I-II and the wheel groove II-II are positioned on the same vertical plane. Based on the foregoing structure, the drive rope 2 can be led from the lower tread of the wheel groove I-I, wound around one half circumference of the wheel groove II-I after being wound around the upper tread of the wheel groove II-I, then wound around the upper tread of the wheel groove I-II from the lower tread of the wheel groove II-I, and further wound around the upper tread of the wheel groove II-II from the lower tread of the wheel groove I-II after one half circumference of the wheel groove I-II, and finally led out from the upper tread of the wheel groove II-II.
In order to achieve a better technical result, the rail unit 3 of the beam body detection rail is also provided with a lift module 10. The lift module 10 has rotatable blades which, when rotated, provide an upward pushing force for assisting the traction of the drive rope 2 to all track units 3.
In addition, the lift module 10 may also include a timing belt, timing pulleys, a pitch motor, and a mount. In the lift module 10, the pitch motor adjusts pitch angles of all blades through a synchronous belt and a synchronous pulley, and then adjusts wind directions of the blades.
In summary, the beam body detection track provided by the invention is formed by connecting a plurality of track units 3 in a chained mode, the adjacent upper edges of two adjacent track units 3 are rotationally connected through a hinge structure, the adjacent lower edges are mutually independent, and a multi-joint serial structure with adjustable side-by-side distribution tracks is formed. Therefore, after all the rail units 3 of the beam body detection rail are hung below the beam body 01, such as a bridge, by the hanging traction piece 1, the bending angles of all the rail units 3 along the side-by-side distribution direction can be adjusted together by the hanging traction piece 1 and the driving ropes 2, so that the side-by-side distribution track of all the rail units 3 can be freely bent or stretched straight or stretched to be consistent with the bottom extension track of the beam body 01, and further different use requirements of the beam body 01 on the beam body detection rail are met. The lifting force module 10 can reduce the requirement on the pulling force of rope driving when the track is deformed, so that an operator can conveniently adjust the side-by-side distribution track of all track units 3 in the beam body detection track.
The beam body detection rail is convenient to disassemble, fold and transport on one hand; on the other hand, the whole weight of the track is reduced, the joint torque requirement is reduced, the track deformation action is simplified, and the device has the advantages of high detection efficiency, low detection cost and low casualty risk of manual high-altitude operation.
When the beam body detection track is used, the suspension traction piece 1 at one end of the beam body detection track can be fixed on the unmanned aerial vehicle, and then the unmanned aerial vehicle is controlled to fly from one side of the bridge to the other side, so that two groups of operators at two sides of the bridge respectively pull the suspension traction pieces 1 at two ends of the beam body detection track, and the rest structure of the beam body detection track is suspended below the beam body 01 to be detected by means of the suspension traction pieces 1. Wherein for bridges of larger span, the beam body detection track typically passes from one width side of the bridge to the other. In order to operate the entire bottom surface of the bridge, the remaining structure of the beam body detection rail may be pulled by the suspension pulling member 1 to move from one end of the length of the bridge to the other end of the length.
Subsequently, a force is applied to the end of the drive rope 2, causing the length of the drive rope 2 defined between all of the track units 3 to increase or decrease.
When the length of the drive rope 2 defined between all the track units 3 is large, the track of all the track units 3 distributed side by side is low in the middle and high at both ends. At this time, the beam body detection rail is in a freely bent state, and any adjacent two rail units 3 are kept hinged only at the adjacent upper edges and separated from each other at the adjacent lower edges.
When the length of the drive rope 2 defined between all the track units 3 is small, the side-by-side distribution trajectory of all the track units 3 is caused to approach a straight line from the above-described freely curved state.
The beam body detection track provided by the invention is described in detail above. The principles and embodiments of the present invention have been described herein with reference to specific examples, the description of which is intended only to facilitate an understanding of the method of the present invention and its core ideas. It should be noted that it will be apparent to those skilled in the art that various modifications and adaptations of the invention can be made without departing from the principles of the invention and these modifications and adaptations are intended to be within the scope of the invention as defined in the following claims.
