Description

Technical Field

[0001] This application relates to the field of auxiliary tools for power maintenance, and in particular to a multi-angle pin replacer for live working. Background Art

[0002] A pole tower is a structure for supporting conductors. An insulator string is installed on the pole tower. One end of the insulator string is fixedly connected to the cross arm in the pole tower, and the other end is connected to the conductor to insulate the conductor from the pole tower. The insulator string includes a bowl head, and the bowl heads are usually connected by an R pin. However, as the service life increases, the R pin may fall off. To ensure the safety of the pole tower and the conductor, pin replacement operations are required.

[0003] When installing the R pin, a person stands on the pole tower. If the installation position of the R pin is in the front of the structure to be pin-replaced, at this time, the operator standing on the pole tower can directly see the installation position of the R pin, then the operator can directly use the existing pin replacer to install the R pin, that is, insert the R pin into the pin replacement position from the direction of the person to the installation position; but if the installation position of the R pin is in the back of the structure to be pin-replaced, at this time, the operator standing on the pole tower cannot see the installation position of the R pin, and at this time, it may be necessary to insert the R pin into the pin replacement position from the direction of the installation position to the person. For this situation, the person needs to slide to the pin replacement position through a suspension rope, but this method has a low safety factor; therefore, in order to improve the operation safety factor, it is an urgent problem to provide a pin replacer that allows a person to install the R pin from the front and from the back when standing on the pole tower. Utility Model Content

[0004] In order to be able to install the R pin from the front and from the back, this application provides a multi-angle pin replacer for live working.

[0005] The multi-angle pin replacer for live working provided by this application adopts the following technical solutions:

[0006] A multi-angle pin replacer for live working, comprising:

[0007] A main rod parallel to the first direction X with one end being the installation end and the other end being the connection end;

[0008] Two transverse clamping strips installed at the installation end of the main rod, the transverse clamping strips are arranged parallel to the second direction Y, the two transverse clamping strips are spaced apart in the third direction Z, and the mutually close surfaces of the two transverse clamping strips are transverse clamping surfaces, and the two transverse clamping surfaces form a transverse clamping area in the third direction Z; and

[0009] A spacing adjustment assembly for driving the transverse clamping strips to move in the third direction Z to change the width of the transverse clamping area.

[0010] By adopting the above technical solution, during pin replacement, if the installation position of the R pin is in the direction away from the operator, the operator only needs to hold the main rod and place the transverse clamping strip on the back of the structure to be pin-replaced. Since the transverse clamping strip and the main rod are perpendicular to each other, at this time, the state formed after the operator holds the main rod is that the structure to be pin-replaced is located between the operator and the transverse clamping strip. Thus, the transverse clamping strip can be pulled from the direction of the structure to be pin-replaced towards the operator to install the R pin clamped between the two transverse clamping strips on the structure to be pin-replaced. If installation from the front is required, only the transverse clamping strip needs to be placed on the side of the structure to be pin-replaced close to the operator. Then, the transverse clamping strip is moved from the operator towards the structure to be pin-replaced to insert the R pin clamped between the transverse clamping strips into the pin replacement position. Therefore, the present application can not only achieve front installation but also achieve back installation. There is no need for the operator to slide to the pin replacement position using a suspension rope and the operation can be carried out while standing on the cross arm, which can improve the safety of the operation.

[0011] Optionally, the spacing adjustment assembly includes:

[0012] Two guiding blocks fixedly connected to the main rod and having guiding portions, the two guiding blocks are spaced apart along the third direction Z. The surfaces of the two guiding portions facing each other are guiding surfaces, and the spacing between the two guiding surfaces gradually increases towards the side away from the main rod. A limiting area with a width gradually increasing towards the side away from the main rod is formed between the two guiding surfaces in the third direction Z;

[0013] A driving rod slidably connected to the main rod along the first direction X, and the driving end of the driving rod extends into the limiting area;

[0014] Two longitudinal clamping strips elastically hinged to the driving end of the driving rod through torsion springs, the two longitudinal clamping strips are located in the limiting area, the longitudinal clamping strips are arranged parallel to the first direction X, and each transverse clamping strip is fixedly connected to one of the longitudinal clamping strips; the rotation axis of the longitudinal clamping strip along the driving rod is parallel to the second direction Y, and the longitudinal clamping strip is always pressed against the guiding surface under the pushing force of the torsion spring.

[0015] By adopting the above technical solution, during pin replacement, the driving rod is moved along the main rod. During this process, the torsion spring pushes the longitudinal clamping strip to always press against the guiding surface, thereby changing the opening size between the two longitudinal clamping strips, that is, changing the spacing between the two transverse clamping strips in the third direction Z. This structure facilitates adjusting the spacing between the two transverse clamping strips in the third direction Z.

[0016] Optionally, it further includes a linear driving member connected between the main rod and the driving rod, and the linear driving member is used to drive the driving rod to move back and forth along the main rod.

[0017] By adopting the above technical solution, when the driving rod needs to slide along the main rod, it is only necessary to drive the driving rod to move along the main rod by a linear driving member, which can facilitate personnel to adjust the distance between the two transverse clamping strips.

[0018] Optionally, it further includes:

[0019] An extension rod;

[0020] A universal adjusting member connected between the extension rod and the main rod, and the main rod is connected to one end of the extension rod through the universal adjusting member.

[0021] By adopting the above technical solution, by setting the extension rod, the working distance can be increased, and by setting the universal adjusting member, the angle change between the extension rod and the main rod can be realized to install the R pin from more angles.

[0022] Optionally, it further includes an image transmission component, and the image transmission component includes:

[0023] A camera connected to the main rod and used for collecting the picture of the transverse clamping strip; and

[0024] A display connected to the extension rod and communicatively connected to the camera, and the display is located at the end of the extension rod away from the main rod.

[0025] By adopting the above technical solution, by setting the camera and the display, it is convenient for personnel to remotely observe the installation state of the R pin.

[0026] Optionally, a first gooseneck tube is connected between the main rod and the camera; and / or

[0027] A second gooseneck tube is connected between the extension rod and the display.

[0028] By adopting the above technical solution, by setting the first gooseneck tube and the second gooseneck tube, it is convenient for personnel to adjust the positions of the camera and the display.

[0029] Optionally, the extension rod is a telescopic rod.

[0030] By adopting the above technical solution, it is convenient to install the R pin from different distances.

[0031] Optionally, on the mutually approaching surfaces of the two transverse clamping strips, first clamping grooves parallel to the second direction Y are respectively formed, and the first clamping grooves penetrate through the transverse clamping strips in the second direction Y.

[0032] By adopting the above technical solution, clamping the R pin in the first clamping groove can reduce the slipping of the R pin on the transverse clamping strip.

[0033] Optionally, on the mutually approaching surfaces of the two transverse clamping strips, second clamping grooves perpendicular to the second direction Y are formed, and the second clamping grooves penetrate through the transverse clamping strips.

[0034] By adopting the above technical solution, clamping the R pin in the second clamping groove can further reduce the slipping of the R pin on the transverse clamping strip.

Detailed implementation manners

[0047] The following further describes the present application in detail with reference to the Figures 1-5 drawings. For the convenience of description, the present application introduces orientation terms such as the first direction X, the second direction Y, and the third direction Z to form a three-dimensional reference direction. The orientation terms such as "the first direction X, the second direction Y, and the third direction Z" can specifically refer to the figure shown, where X represents the first direction X, Y represents the second direction Y, Z represents the third direction Z, and the first direction X, the second direction Y, and the third direction Z are perpendicular to each other in pairs.

[0048] An embodiment of the present application discloses a multi-angle pin replenisher for live working. Referring to Figure 1 and Figure 2 , the multi-angle pin replenisher for live working includes a main rod 1, a transverse clamping strip 2, and a spacing adjustment component 3. The main rod 1 is parallel to the first direction X, and one end of the main rod 1 is a mounting end 11, and the other end is a connecting end 12. Two transverse clamping strips 2 are provided at the mounting end 11 of the main rod 1. The transverse clamping strips 2 are arranged parallel to the second direction Y. The two transverse clamping strips 2 are spaced apart in the third direction Z. The mutually approaching wall surfaces of the two transverse clamping strips 2 are transverse clamping surfaces 21. The two transverse clamping surfaces 21 form a transverse clamping area 22 in the third direction Z. The transverse clamping strips 2 can move in the third direction Z to change the spacing between the two transverse clamping strips 2 in the third direction Z, that is, to change the width of the transverse clamping area 22. The spacing adjustment component 3 is used to drive the transverse clamping strips 2 to move in the third direction Z.

[0049] Referring to Figure 2 , when the R pin 01 is clamped by the two transverse clamping strips 2, in order to reduce the slipping of the R pin 01 on the transverse clamping strips 2, the transverse clamping strips 2 are provided with a first clamping groove 23 and a second clamping groove 24 on the transverse clamping surface 21;

[0050] The length direction of the first clamping groove 23 is parallel to the second direction Y, and the first clamping groove 23 penetrates the transverse clamping strip 2 in the second direction Y.

[0051] The length direction of the second clamping groove 24 is perpendicular to the second direction Y, and it penetrates the transverse clamping strip 2 along the direction perpendicular to the second direction Y.

[0052] Refer to Figure 2 and Figure 3 As shown in FIGS. and, the spacing adjustment assembly 3 includes a guide block 32 fixedly connected to the main rod 1 and having a guide portion 321 and a connecting portion 322, a driving rod 33 slidably connected to the main rod 1 in the first direction X, and two longitudinal clamping strips 34.

[0053] In the present disclosure, the main rod 1 is a cylindrical tube, and a connecting plate 31 perpendicular to the main rod 1 is fixedly connected to the end wall of the installation end 11 of the main rod 1; there are two guide blocks 32, the connecting portion 322 of the guide block 32 is fixedly connected to one end of the connecting plate 31 away from the main board, and the guide portion 321 is located at one end of the guide block 32 away from the connecting plate 31; the two guide blocks 32 are spaced apart in the third direction Z, and a gap for the driving end of the driving rod 33 to pass through is formed between the two connecting portions 322 in the third direction Z. One side of the two guide portions 321 close to each other is a guide surface 3211, and a limiting area 3212 for accommodating the longitudinal clamping strip 34 is formed between the two guide surfaces 3211 in the third direction Z. The distance between the two guide surfaces 3211 gradually increases in the direction from the connecting portion 322 to the guide portion 321. That is to say, the width of the limiting area 3212 gradually increases toward the side away from the main rod 1.

[0054] There are two longitudinal clamping strips 34. The longitudinal clamping strips 34 are located in the limiting area 3212, and there are two longitudinal clamping strips 34 distributed in the third direction Z. The long sides of the longitudinal clamping strips 34 are arranged parallel to the first direction X. Guide edges 341 are convexly provided on the sides of the two longitudinal clamping strips 34 away from each other, and the guide edges 341 are always in contact with the guide surface 3211; the longitudinal clamping strips 34 are elastically hinged to the driving rod 33.

[0055] When the two longitudinal clamping strips 34 move toward the side away from the main rod 1, the two longitudinal clamping strips 34 rotate toward the side away from each other to increase the opening between the two longitudinal clamping strips 34. The rotation axis of the longitudinal clamping strips 34 is parallel to the second direction Y.

[0056] When the two longitudinal clamping strips 34 move toward the side close to the main rod 1, the two longitudinal clamping strips 34 rotate toward the side close to each other to reduce the opening between the two longitudinal clamping strips 34.

[0057] In some embodiments of the present application, in order to elastically hinge the longitudinal clamping strip 34 to the driving rod 33, the driving rod 33 passes through the connecting plate 31 and the main rod 1 and can slide along the connecting plate 31 and the main rod 1 in the first direction X. A hinge seat 35 is fixedly connected to the driving end of the driving rod 33. One end of the longitudinal clamping strip 34 close to the connecting plate 31 is the hinge end 342, and the end far from the connecting plate 31 is the free end 343. The longitudinal clamping strip 34 is rotatably connected to the hinge seat 35 through a rotating shaft. The rotating shaft is located at the hinge end 342 of the longitudinal clamping strip 34. A torsion spring 36 is provided between the longitudinal clamping strip 34 and the hinge seat 35. One end of the torsion spring 36 is fixedly connected to the hinge seat 35, and the other end is fixedly connected to the hinge end 342 of the longitudinal clamping strip 34. The torsion spring 36 has a force that always pushes the guiding edge 341 of the longitudinal clamping strip 34 to abut against the guiding surface 3211.

[0058] During use, only by moving the driving rod 33 back and forth in the first direction X, the size of the two longitudinal clamping strips 34 can be increased or decreased; each transverse clamping strip 2 is detachably connected to the free end 343 of a longitudinal clamping strip 34 respectively. Thus, when the driving rod 33 moves, the distance between the two transverse clamping strips 2 in the third direction Z is changed.

[0059] Referring to Figure 2 and Figure 3 , in the present disclosure, after the transverse clamping strip 2 is removed, the longitudinal clamping strip 34 can also be used as a structure for clamping the R pin 01. For this purpose, the surfaces of the two longitudinal clamping strips 34 facing each other are longitudinal clamping surfaces 344. The longitudinal clamping strip 34 is provided with a third clamping groove 345 and a fourth clamping groove 346 on the longitudinal clamping surface 344. The length direction of the third clamping groove 345 is parallel to the second direction Y, and the third clamping groove 345 penetrates the longitudinal clamping strip 34 in the second direction Y. The length direction of the fourth clamping groove 346 is perpendicular to the second direction Y, and the fourth clamping groove 346 penetrates the end of the longitudinal clamping strip 34 far from the hinge seat 35.

[0060] Referring to Figure 4, in order to move the driving rod 33 in the first direction X so as to drive the transverse clamping strip 2 and the longitudinal clamping strip 34 to move by the driving rod 33, in some embodiments of the present application, a linear driving member 4 is further included. The linear driving member 4 is connected between the driving rod 33 and the main rod 1 to drive the driving rod 33 to move along the main rod 1. In the present disclosure, the linear driving member 4 is an electric push rod. The cylinder body of the linear driving member 4 is directly or indirectly fixedly connected to the main rod 1, and the push rod of the linear driving member 4 is fixedly connected to the driving rod 33. In order to install the linear driving member 4, the main rod 1 is provided with a straight rod 13 and a support seat 14 at the connection end 12. The support seat 14, the straight rod 13 and the main rod 1 are sequentially distributed in the first direction X. One end of the straight rod 13 is fixedly connected to the main rod 1, and the other end is fixedly connected to the support seat 14. Four straight rods 13 are circumferentially and uniformly distributed along the main rod 1. The linear driving member 4 is located in the area surrounded by the four straight rods 13, and the cylinder body of the linear driving member 4 is fixedly connected to the support seat 14.

[0061] Referring to Figure 5 , further, in order to install the R pin 01 from more angles, in some embodiments of the present application, an extension rod 7 and a universal adjusting member 5 connected between the extension rod 7 and the main rod 1 are further included. The universal adjusting member 5 includes a universal ball seat 51, a universal ball body 52 and a locking screw 53. The universal ball seat 51 is fixedly connected to one end of the extension rod 7. The universal ball body 52 is freely rotatably connected to the universal ball seat 51 in a matching manner. The main rod 1 is directly or indirectly fixedly connected to the universal ball body 52. In the present disclosure, the main rod 1 is fixedly connected to the universal ball body 52 through the support seat 14 to realize the universal hinge between the main rod 1 and the extension rod 7. After rotating the main rod 1 and the extension rod 7 to the required position, the locking screw 53 is passed through the universal ball seat 51 and then abutted against the universal ball body 52. The locking screw 53 is threadedly connected to the universal ball seat 51, so that the universal ball body 52 can be fixed to the universal ball seat 51, that is, the main rod 1 can be fixedly connected to the extension rod 7.

[0062] Referring to Figure 5 , when installing the R pin 01, the operator can stand on the pole tower. Then, hold the extension rod 7 to install the R pin 01 to the required position. In order to facilitate the operator to observe the installation state of the R pin 01, in some embodiments of the present application, an image transmission component 6 is further included. The image transmission component 6 includes a camera 61 connected to the main rod 1 and used for collecting the images of the transverse clamping strip 2 and the longitudinal clamping strip 34, and a display 62 installed on the extension rod 7. The display 62 is communicatively connected to the camera 61 to display the images collected by the camera 61 in real time. In the present disclosure, a holding rod 71 is fixedly connected to the end of the extension rod 7 away from the main rod 1. The holding rod 71 is perpendicular to the extension rod 7, and the display 62 is connected to the holding rod 71.

[0063] Further, in some embodiments of the present application, a first gooseneck tube 611 is fixedly connected between the camera 61 and the main rod 1, and / or a second gooseneck tube 621 is fixedly connected between the display 62 and the extension rod 7.
