Description

Technical Field

[0001] This invention relates to the field of railway line inspection and bridge crossing technology, and in particular to a bridge crossing device. Background Technology

[0002] Tension towers are equipped with insulators, typically horizontally positioned, and are a crucial component of transmission lines. Insulators provide segmented insulation while maintaining the position of each conductor, effectively isolating energized conductors from the ground and increasing the safety of the transmission line environment. During the daily operation and maintenance of transmission lines, the complex and variable geographical environment and weather conditions inevitably damage the insulators. Insulators are the most common product in transmission lines, often used in conjunction with matching hardware to achieve the function of high-voltage porcelain insulation. Furthermore, in practical applications, construction teams often combine several insulators together to meet the tension requirements of the transmission line, depending on the needs of power system construction.

[0003] For example, the patent application number CN205595740U shows a bridge-crossing device to help inspection robots cross towers. By using inspection robots to inspect high-voltage transmission lines, a bridge-crossing device needs to be set up when the inspection robot encounters a tower so that the inspection robot can pass through the tower.

[0004] However, the tower-crossing device in the aforementioned patent lacks corresponding insulation design. If it is directly installed on a tension tower equipped with insulators, it will conduct the circuit, preventing the insulators from performing their original function and failing to meet the safety insulation requirements of the tower. Summary of the Invention

[0005] The purpose of this invention is to address the deficiencies in the prior art by proposing a bridge crossing device. This device divides the line insulation into three sections—front, middle, and rear—by setting a first insulation component and a second insulation component in sections between the traveling guide rail and the tower, and by setting an independent third insulation component in sections of the traveling guide rail.

Detailed Implementation

[0055] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and should not be construed as limiting the present invention.

[0056] In the description of this invention, it should be understood that the terms "upper," "lower," etc., indicating orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0057] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0058] For example, patent application number CN205595740U discloses a bridge-crossing device to help inspection robots cross towers. By using inspection robots to inspect high-voltage transmission lines, a bridge-crossing device needs to be set up when the inspection robot encounters a tower so that the inspection robot can pass through the tower.

[0059] Current tension towers come with two existing insulators when no bridge crossing device is installed; however, the bridge crossing device in the aforementioned patent does not have a corresponding insulation design. If it is directly built on a tension tower with insulators, it will conduct electricity, preventing the insulators from performing their original function and failing to meet the safety insulation requirements of the tower.

[0060] To solve the above problems, this application proposes a bridge crossing device, which is installed on a pole tower. The bridge crossing device includes a traveling guide rail 3 and a support member 4. The two ends of the traveling guide rail 4 are connected to the ground wire, and the ground wire 12 is connected to the pole tower through the ground wire's inherent insulator.

[0061] The pole is connected and fixed in the middle of the walking guide rail 3 by a support member 4;

[0062] The walking guide rail 3 is equipped with an insulating device to insulate the walking guide rail 3 from the tower.

[0063] In this embodiment, two ground wires 12 extend from the left and right sides of the tower, respectively. One end of the walking guide rail 3 is connected to one of the ground wires 12, and the other end of the walking guide rail 3 is connected to the other ground wire 12. The two ground wires 12 are equipped with inherent ground wire insulators between them and the tower, so that the ground wires 12 and the tower are in an insulated state. However, since the walking guide rail 3 is directly connected to the two ground wires 12, the walking guide rail 3 is in a conductive state. Since the walking guide rail 3 needs to be connected and fixed to the tower through the support member 4, the tower will also be in a conductive state, which does not meet the installation insulation requirements of the tower. Therefore, it is necessary to ensure that the walking guide rail 3 and the tower are in an insulated state. This application achieves the insulation state between the walking guide rail 3 and the tower by installing the insulation device on the walking guide rail 3.

[0064] Specifically, in one embodiment of this application, the bridge crossing device includes a steel strand 2, which is connected to two ground wires 12 of the tower via a left-clamping branch clamp 10 and a right-clamping branch clamp 11, respectively. The steel strand 2 is fitted with a travel guide rail 3, and the travel guide rail 3 is equipped with a support member 4 to achieve fixed installation with the tower through the support member 4.

[0065] Preferably, the walking guide rail 3 is equipped with at least one insulating device;

[0066] The insulating device includes any one or more combinations of a first insulating component 5, a second insulating component 6, or a third insulating component 7. (Refer to...) Figures 1 to 9 As shown, the insulating device includes a first insulating component 5, a second insulating component 6, and a third insulating component 7, which are installed in sections on the traveling guide rail 3.

[0067] The existing tension tower structure has two existing insulators. One ground wire 12 is connected to the tension tower through one of the insulators, and the other ground wire 12 is connected to the tension tower through the other insulator. However, the bridging device is installed on the tension tower, and the steel strand 2 of the bridging device is connected to the two ground wires 12 of the tower through the left clamp-type branch clamp 10 and the right clamp-type branch clamp 11 respectively. This means that the bridging device is not insulated. In this application, an insulating device is set on the traveling guide rail 3 of the bridging device. The first insulating component 5, the second insulating component 6 and the third insulating component 7 are set in sections on the traveling guide rail 3 to achieve a segmented insulating effect. Similarly, the first insulating component 5 alone, or the second insulating component 6 alone, or the third insulating component 7 alone, or any combination thereof can achieve the effect of insulation between the traveling guide rail and the tower.

[0068] Specifically:

[0069] The first insulating component 5 includes a first connecting part, a first fixing part, and a first insulating part. The first connecting part and the first fixing part are installed and cooperated to make the first insulating part fixedly connect the traveling guide rail 3 and the tower.

[0070] Furthermore, in this embodiment, the installation and cooperation between the first connecting part, the first fixing part, and the first insulating part may include the following specific structure;

[0071] One end of the first connecting part is connected to the support member 4 of the walking guide rail 3, and the other end is connected to the pole tower;

[0072] In this embodiment, the two ends of the first connecting part are respectively connected to the support member 4 and the tower, and the support member 4 is fixedly installed with the walking guide rail 3, so the walking guide rail 3 and the tower can be connected through the first connecting part;

[0073] The first connecting part is provided with a first insulation installation position, and the first fixing part fixes the first insulation part to the first insulation installation position;

[0074] In this embodiment, since the first connecting part is equivalent to the connecting part between the walking guide rail 3 and the tower, the present application sets a first insulation installation station in the first connecting part to fix the first insulation part to the first connecting part, thereby achieving the insulation effect between the walking guide rail 3 and the tower, which is equivalent to achieving insulation between a part of the bridge crossing device and the tower.

[0075] Furthermore, in this embodiment, the first fixing part mainly serves to stabilize the first insulating part. It is not enough for the first insulating part to achieve stability with the first connecting part by relying solely on the first insulating installation position. Therefore, this application provides a first fixing part to further fix the first insulating part and prevent the first insulating part from falling off the first connecting part.

[0076] To better illustrate the technical solution of this application, this application is combined with the appendix. Figure 1 Appendix Figure 2 and attached Figure 5 The preferred embodiments will be further described below;

[0077] Specifically, the first connecting part includes a first stiffening plate 51, the first fixing part includes a first connecting plate 52, and the first insulating part includes a first double stud insulator 53.

[0078] One end of the first stiffening plate 51 is connected to the support member 4, and the other end is connected to the tower;

[0079] The two sides of the first stiffening plate 51 extend outward to form two first insulating mounting plates 54. The two first insulating mounting plates 54 and the plate of the first stiffening plate 51 form a cross structure. The two first insulating mounting plates 54 are respectively provided with the first insulating mounting position.

[0080] The first connecting plate 52 has an L-shaped structure;

[0081] One end of the first double stud insulator 53 is installed at the first insulation installation position, and the other end is fixed to the first connecting plate 52.

[0082] In the preferred embodiment, holes are provided at both ends of the first stiffening plate 51. The hole at one end is fixed to the support member 4 by means of bolt connection. The specific fixing structure will be explained in detail below. The hole at the other end is aligned with the existing installation holes of the tower head of the tower and connected by bolts, so that the first stiffening plate 51 forms a connecting bridge.

[0083] Meanwhile, on the two sides of the middle part of the first stiffening plate 51, two first insulating mounting plates 54 extend outward from the left and right respectively. The two first insulating mounting plates 54 and the plate of the first stiffening plate 51 form a cross structure. The two first insulating mounting plates 54 and the first stiffening plate 51 are integrally formed. At the same time, each first insulating mounting plate 54 is provided with a first insulating mounting position. In this embodiment, the first insulating mounting position is a mounting hole. The bottoms of the two first double stud insulators 53 are installed on the two first insulating mounting plates 54 from the left and right respectively.

[0084] Furthermore, in this embodiment, the first connecting plate 52 has an L-shaped structure, that is, the first connecting plate 52 can be understood as an L-shaped folded plate. The side of the first connecting plate 52 that forms a cavity faces the first double stud insulator 53, and the first connecting plate 52 is fixed to the top of the first double stud insulator 53 by bolts.

[0085] Preferred, such as Figure 9 As shown, the minimum installation distance between the first connecting part and the first fixing part is greater than the minimum discharge distance 9 of the inherent insulator of the ground wire 12.

[0086] In this embodiment, it means that the minimum installation distance between the first connecting plate 52 and the first stiffening plate 51 should be greater than the minimum discharge distance 9 of the inherent insulator of the ground wire 12;

[0087] When the insulation distance of the first studded insulator 53 is less than the discharge distance 9 of the existing insulator, a discharge will occur, connecting the first studded insulator 53 and thus connecting the traveling guide rail 3, making segmented insulation impossible. Therefore, the minimum installation distance between the first stiffening plate 51 and the first connecting plate 52 must be greater than the minimum discharge distance 9 of the existing insulator. This ensures that the insulation performance of the installed insulator is better than that of the existing insulator, preventing discharge and thus providing insulation for the entire insulation assembly.

[0088] Preferably, the second insulating component 6 includes a second connecting part, a second fixing part, and a second insulating part. The second connecting part and the second fixing part are installed and cooperated to make the second insulating part fixedly connect the traveling guide rail 3 and the tower.

[0089] In this embodiment, the mounting structure between the second connecting part, the second fixing part, and the second insulating part can specifically be as follows:

[0090] The second fixing part is provided with a second insulation installation position, and the second insulation part is installed at the second insulation installation position;

[0091] The second fixed part connects the second connecting part and the tower respectively;

[0092] The second connecting part is connected to and installed with the walking guide rail 3;

[0093] In this embodiment, the second connecting part is connected to the walking guide rail 3, the second fixing part is connected to the pole tower, and the second connecting part is connected to the second fixing part, thereby realizing the connection between the walking guide rail 3 and the pole tower. In order to achieve the insulation effect, this application sets a second insulation installation station on the second fixing part, and installs the second insulation part on the second insulation installation station, thereby achieving the insulation effect between the walking guide rail 3 and the pole tower.

[0094] To better illustrate the insulation technology of the second insulation component 6 in this application, this application combines the appendix... Figure 1 Appendix Figure 2 and attached Figure 6 The preferred embodiments will be further described below;

[0095] Specifically, the second connecting part includes a second stiffening plate 61, the second fixing part includes a second connecting plate 62 and a second fixing plate 63, and the second insulating part includes a second double stud insulator 64.

[0096] The second connecting plate 62 has an L-shaped structure. The mounting end of the second connecting plate 62 is provided with a second insulation mounting position. One end of the second double stud insulator 64 is installed at the second insulation mounting position, and the other end of the second double stud insulator 64 is connected to the second fixing plate 63.

[0097] The second fixing plate 63 is connected and installed on the tower;

[0098] The connecting end of the second connecting plate 62 is fixed to the second stiffening plate 61, and the walking guide rail 3 is installed on the surface of the second stiffening plate 61.

[0099] In the preferred embodiment, the second stiffening plate 61 is an L-shaped folded plate, and triangular plates are installed on the two right-angled sides of the L-shaped folded plate to further enhance stability. One end of the second stiffening plate 61 is connected to the walking guide rail 3 by welding the walking guide rail 3 to the second stiffening plate 61 with bolts. The other end of the second stiffening plate 61 is connected to the second connecting plate 62.

[0100] The second connecting plate 62 serves to connect the second stiffening plate 61 and also to fix the two second double stud insulators 64. The fixing method is that the plate surface of the second connecting plate 62 is connected to the top of the second double stud insulator 64.

[0101] The second fixing plate 63 is placed below the second connecting plate 62 and has a second insulation installation position for installing two second double stud insulators 64. At the same time, the second fixing plate 63 is also connected to the pole, realizing the connection between the second insulation component 6 and the pole. The specific connection method between the second fixing plate 63 and the pole will be described in detail below when describing the pole.

[0102] The minimum installation distance between the second connection part and the second insulation part is greater than the minimum discharge distance 9 of the inherent insulator of the ground wire 12.

[0103] When the insulation distance of the second studded insulator 64 is less than the discharge distance 9 of the existing insulator, a discharge will occur, connecting the second studded insulator 64 and subsequently the traveling guide rail 3, making segmented insulation impossible. Therefore, the minimum installation distance between the second stiffening plate 61 and the second studded insulator 64 must be greater than the minimum discharge distance 9 of the existing insulator. This ensures that the insulation performance of the installed insulator is better than that of the existing insulator, preventing discharge and thus providing insulation for the entire insulation assembly.

[0104] The third insulating component 7 includes a third fixing part and a third insulating part. One end of one segment of the walking guide rail 3 is equipped with the third fixing part, and another end of the other segment of the walking guide rail 3 is equipped with the third fixing part. The third insulating part is installed and cooperates with the two third fixing parts respectively to connect the two segments of the walking guide rail 3.

[0105] In this embodiment, when the third insulation component 7 is independently installed on the travel guide rail 3, the travel guide rail 3 is segmented into at least two segments. The two segments of the travel guide rail 3 are connected by the third insulation component 7 to achieve segmented insulation of the travel guide rail 3. The third insulation component 7 specifically includes the following structure:

[0106] The third fixing part is provided with a fixing end 72, and the two ends of the third insulating part are respectively provided with mating ends 73;

[0107] The fixed end 72 of one segment of the walking guide rail 3 is fitted into one of the fitting ends 73 of the third insulating part, and the fixed end 72 of another segment of the walking guide rail 3 is fitted into another fitting end 73, so that one segment of the walking guide rail 3 is connected to the other segment of the walking guide rail 3.

[0108] In this embodiment, the walking guide rail 3 is divided into two sections, named the first guide rail and the second guide rail respectively. The first guide rail has a fixed end 72 at one end, and the second guide rail also has a fixed end 72 at one end. The first guide rail is connected to the third insulating part by fitting the fixed end 72 of the first guide rail into one of the fitting ends 73 of the third insulating part. The second guide rail is connected to the third insulating part by fitting the fixed end 72 of the second guide rail into the other fitting end 73 of the third insulating part. Thus, the first guide rail is connected to the second guide rail through the third insulating part.

[0109] In another embodiment, the walking guide rail 3 is divided into two sections, named the third guide rail and the fourth guide rail respectively. The third guide rail has a fixed end 72 at one end, and the fourth guide rail has a third insulating part at one end. The fourth guide rail and the third insulating part are integrally formed. The third insulating part has a mating end 73. The connection between the third guide rail and the fourth guide rail is achieved by fitting the fixed end 72 of the third guide rail into the mating end 73 of the third insulating part.

[0110] Furthermore, to more clearly illustrate the technical solution of this application regarding the third insulating component 7, this application, in conjunction with the appendix... Figure 1 Appendix Figure 2 and attached Figure 7 The preferred embodiments are described in detail below;

[0111] Preferably, the third fixing part includes a fixing sleeve 71, and the fixing end 72 is formed by the middle part of the fixing sleeve 71 protruding in the direction of the opening of the fixing sleeve 71. The fixing end 72 is a bolt.

[0112] The mating end 73 of the third insulating part is a screw hole formed by an inward recess, and the screw hole corresponds to the bolt.

[0113] The third insulating part is installed on the third fixing part with a clearance fit by inserting the bolt into the screw hole.

[0114] In the preferred embodiment, the system includes two travel rails 3. One end of one travel rail 3 is fitted with the fixing sleeve 71. The fixing sleeve 71 is hollow inside to form an installation chamber. The bottom center of the installation chamber protrudes towards the opening of the installation chamber to form the fixing end 72. The fixing end 72 is a bolt with positive and negative threads. Similarly, the other end of the travel rail 3 is fitted with the above structure.

[0115] Next, the third insulating component 7 exists as an independent object. In this embodiment, the third insulating part is a strip-shaped barrel structure, and the cross-sections of the two ends of the third insulating part are the same shape as the cross-section of the opening of the fixing sleeve 71. The middle part of the cross-sections of the two ends of the third insulating part is recessed inward to form the mating end 73, and the mating end 73 is a screw hole with positive and negative threads.

[0116] By aligning the screw holes at the two ends of the third insulating part with the bolts of the two sections of the travel guide rail 3, the third insulating part is fixed between the two sections of the travel guide rail 3 by rotation, so that the two sections of the travel guide rail 3 are connected to each other through the third insulating part;

[0117] It should be noted that the diameter of the cross section at the two ends of the third insulating part is smaller than the diameter of the cross section at the opening of the fixing sleeve 71, so that the mating end 73 of the third insulating part can enter the fixing sleeve 71, so that the screw hole can be threaded with the bolt.

[0118] The minimum installation distance between the two sections of the travel guide rail 3 is greater than the minimum discharge distance 9 of the inherent insulator of the ground wire 12.

[0119] Similarly, when the installation distance of the third insulation part is less than the discharge distance 9 of the existing insulator, the third insulation part will be connected by discharge, which in turn will connect the traveling guide rail 3, defeating the original purpose of segmented insulation. Therefore, the minimum distance between the left and right traveling guide rails 3 connected to the third insulation part must be greater than the inherent discharge distance 9 of the ground wire 12 insulator, that is, to ensure that the insulation performance of the installed insulator is better than that of the existing insulator.

[0120] In this embodiment, as Figure 1 and Figure 2 As shown, the left-clamping branch clamp 10 and the right-clamping branch clamp 11 are respectively installed on the two ground wires 12 on the outside of the tower; the left-clamping branch clamp 10 is connected to the steel strand 2 by crimping to ensure strength, and the steel strand 2 is made of flexible material to adapt to various bridge crossing devices; at the same time, a certain amount of slack is left in the left and right clamps to ensure that the embedding slack is 200mm, and the crimping position needs to be ensured to prevent the steel strand 2 from falling off;

[0121] Furthermore, the walking guide rail 3 and the steel strand 2 are embedded in each other, that is, the steel strand 2 can be fitted into the walking guide rail 3.

[0122] The upper end face of the walking guide rail 3 is provided with a U-shaped locking groove 44;

[0123] The support member 4 includes a clamping support plate 41, a U-shaped washer 42, and a U-shaped locking bolt 43;

[0124] The U-shaped gasket 42 is fixed to the pressing support plate 41, and the U-shaped gasket 42 is provided with a U-shaped support groove 45;

[0125] The lower end face of the walking guide rail 3 is attached to the U-shaped support groove 45, and the body of the U-shaped locking bolt 43 is locked into the U-shaped locking groove 44 and fixed to the pressing support plate 41;

[0126] The insulating device includes any one or more combinations of the first insulating component 5, the second insulating component 6, or the third insulating component 7, which are installed in sections on the traveling guide rail 3.

[0127] The first connecting part of the first insulating component 5 is fixedly installed with the clamping support plate 41;

[0128] The second connecting part of the second insulating component 6 is fixedly installed with the walking guide rail 3;

[0129] The third insulating component 7 is installed and cooperates with the third fixing part of each of the two segments of the travel guide rail 3 through the third insulating part, so as to connect the two segments of the travel guide rail 3.

[0130] In this embodiment, as Figure 3 and Figure 4 As shown, the walking guide rail 3 needs to be fixed by the support member 4 to enhance its stability. Specifically, the lower end face of the walking guide rail 3 is attached to the U-shaped support groove 45 of the U-shaped pad 42, and a U-shaped locking groove 44 is opened on the upper end face of the walking guide rail 3. Then, the U-shaped locking bolt 43 is locked into the U-shaped locking groove 44, and then the U-shaped locking bolt 43 is fixed to the pressure support plate 41, thereby achieving a stable installation of the support member 4 and the walking guide rail 3.

[0131] Furthermore, taking the structure of the preferred embodiment of each insulating component mentioned above as the basis for explanation, the hole at one end of the first stiffener 51 of the first insulating component 5 is fixed to the clamping support plate 41 by means of bolt connection; the second stiffener 61 of the second insulating component 6 has a hole, and the second stiffener 61 is fixed to the walking guide rail 3 by bolt passing through the walking guide rail 3 and the hole, so as to use the second stiffener 61 to support the walking guide rail 3 and ensure the stability of the walking guide rail 3.

[0132] Preferably, the mounting positions of the left clamp-type splitter 10, the right clamp-type splitter 11, and the ground wire 12 are respectively wrapped with aluminum tape of a preset thickness.

[0133] Depending on the radius of the ground wire 12, when installing the splitter clips, aluminum tape of a certain thickness can be wrapped around the corresponding position of the splitter clips on the ground wire 12 to ensure that the two splitter clips can be installed stably on the ground wire 12, so that the inspection robot will not cause the two splitter clips to rotate when it passes through them.

[0134] In this embodiment, the tower may include the following structure:

[0135] The tower includes a tower head reinforcement assembly, which includes a clamping clamp 81, a first angle steel 82, a second angle steel 83, and a clamping clamp 84.

[0136] The clamping fixture 81 includes a clamping end and a connecting end. The clamping end is locked in the reserved gap between the first angle steel 82 and the second angle steel 83 by fixing the two clamping fixtures 84 to the first angle steel 82 and the second angle steel 83 respectively.

[0137] The connecting end extends toward the second fixing part of the second insulating component 6 and is fixedly installed with the second fixing part.

[0138] In this embodiment, as Figure 8 As shown, the tower is equipped with the aforementioned bridge device featuring insulation through the tower head reinforcement assembly; specifically:

[0139] The first angle steel 82 and the second angle steel 83 are arranged side by side, with a reserved installation space between them for the clamping end of the clamping fixture 81. The clamping end of the clamping fixture 81 is perpendicular to the connecting end of the clamping fixture 81. The clamping end is inserted into the reserved installation space, so that the connecting end is mounted on the upper surface of the first angle steel 82 and the second angle steel 83. At the same time, two clamping fixtures 84 are used to lock the first angle steel 82 to one side of the clamping end and the second angle steel 83 to the other side of the clamping end, thus completing the fixation of the clamping fixture 81 to the first angle steel 82 and the second angle steel 83.

[0140] Furthermore, the connecting end of the clamping fixture 81 extends toward the second fixing plate 63 and is installed with the second fixing plate 63 by means of welding or bolt connection, thereby enabling the tower to be connected to the bridge device through the second insulating component 6.

[0141] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
