Description

Technical Field

[0001] This invention belongs to the field of power equipment technology, and in particular relates to an R-type pin mounting device for suspension clamps. Background Technology

[0002] The suspension clamp and the mounting plate are connected by through pins, while bolts or pins are locked between the suspension clamp and the mounting plate by passing an R-shaped pin through the pin hole. Due to prolonged use, factors such as aging of the R-shaped pin, reduced elasticity, and external forces can cause the R-shaped pins on the transmission line suspension clamp to frequently fall off after a long period of use. This can lead to the bolt, nut, or pin coming loose or falling off, causing the suspension clamp to lose its connection with the mounting plate and resulting in accidents such as conductor detachment.

[0003] For example, Chinese invention CN202210389085.1 discloses a suspended wire clamp pin live installation device based on photoelectric sensor. By setting up a light receiver and a light emitter, the device can locate the pin hole position of the pin shaft. The device can also drive the pin shaft to rotate through a sleeve to adjust the position of the pin hole on the pin shaft. Finally, the device can use an electric gripper to drive the pin to be inserted into the pin hole of the pin shaft.

[0004] However, the above technical solutions cannot flexibly adjust the position of the device. For example, if the orientation of the pin hole is not horizontal or vertical, it will be inconvenient to adjust the position of the device. The position needs to be adjusted manually to determine the position of the pin hole, which makes the positioning process cumbersome and the overall flexibility and convenience of use poor. Summary of the Invention

[0005] The purpose of this invention is to provide an R-type pin mounting device for suspension clamps. By driving the mounting frame to rotate with a motor, the positioning ball and clamping block rotate along the bolt or pin shaft, so that the positioning ball can accurately position the pin hole, thus solving the problems of poor flexibility and convenience in existing devices.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0007] This invention relates to an R-type pin mounting device for a suspension clamp, comprising a mounting box, and an electrical device and a motor mounted inside the mounting box. A link bar is fixedly connected to the mounting box. The output shaft of the motor passes through the side wall of the mounting box and is fixedly connected to a mounting frame. The mounting frame is slidably connected to a mounting plate and a side plate, and is fixedly connected to an electric push rod, a guide rod, and a photoelectric sensor. A positioning sleeve concentrically arranged with the motor's output shaft is fixedly connected to the mounting frame. The side of the mounting plate is connected to the telescopic end of the electric push rod. A clamping block is fixedly connected to the mounting plate, and the clamping block has an opening for placing... The R-type pin has a clamping groove; the side plate is fixedly connected to a guide plate, a strip plate, and a positioning ball corresponding to the position of the clamping groove, which is used to cooperate with the end of the bolt or pin through the positioning sleeve, so that the motor drives the positioning ball and the clamping block to rotate around the bolt or pin; the guide plate has a through hole that cooperates with the guide rod, and the guide rod is fitted with a spring, which is used to push the positioning ball towards the clamping block through the spring, and when the positioning ball corresponds to the pin hole of the bolt or pin, the strip plate triggers the photoelectric sensor, and the electric push rod drives the mounting plate, so that the R-type pin is inserted into the pin hole.

[0008] As a preferred embodiment of the present invention, the mounting plate is fixedly connected to a U-shaped plate, and several guide rods are fixedly connected between the two side walls of the U-shaped plate. The guide rods are arranged parallel to the positioning sleeve and are fitted with compression springs. The clamping block has a through hole that fits with the guide rods with a clearance. The clamping block has a wedge-shaped part on its side, and the mounting frame is fixedly connected to a stop rod. When the mounting plate drives the clamping block to insert the R-shaped pin into the pin hole and continues to move, the stop rod cooperates with the wedge-shaped part to make the clamping block move axially along the guide rod, so that the R-shaped pin disengages from the clamping groove.

[0009] As a preferred embodiment of the present invention, the mounting bracket is fixedly connected to a support plate with a positioning sleeve vertically arranged, and the support plate has a positioning slot.

[0010] As a preferred embodiment of the present invention, the clamping groove includes a circular recess that mates with the head of an R-shaped pin, and a rectangular recess that communicates with the circular recess.

[0011] As a preferred embodiment of the present invention, the clamping block is fixedly connected to an arc-shaped pressure plate, which is located above the circular groove and is used to allow the R-pin to continue to be pushed by the arc-shaped pressure plate after it is disengaged from the clamping groove.

[0012] As a preferred embodiment of the present invention, the inner surface of the arc-shaped pressure plate is flush with the upper edge of the circular groove.

[0013] As a preferred embodiment of the present invention, the positioning sleeve is provided with fan-shaped slots corresponding to the positions of the positioning ball and the clamping block.

[0014] The present invention has the following beneficial effects:

[0015] This invention uses a motor to drive the mounting bracket to rotate, causing the positioning ball and clamping block to rotate along the bolt or pin shaft. This allows the positioning ball to accurately locate the pin hole. When the positioning ball couples with the pin hole, the position of the side plate changes. The strip plate triggers the photoelectric sensor, thereby further accurately determining the pin hole position. This makes the overall positioning process simpler and more accurate, effectively improving the overall flexibility and convenience of use.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0031] Example 1

[0032] Please see Figures 1-3 As shown, the present invention is an R-type pin mounting device for suspension clamps, including a mounting box 1, and an electrical device and a motor 2 installed inside the mounting box 1. The electrical device includes a battery, control components, etc. The mounting box 1 is fixedly connected to a linker.

[0033] like Figure 4 and 5 As shown, the output shaft of motor 2 passes through the side wall of mounting box 1 and is fixedly connected to mounting bracket 3. The cross-section of mounting bracket 3 is U-shaped. The inner wall of mounting bracket 3 is slidably connected to mounting plate 4 and side plate 5 through guide rail slider mechanism. Electric push rod 301, guide rod 302 and photoelectric sensor 303 are fixedly connected to the inner wall of mounting bracket 3. Connecting plate is welded between the two side walls of mounting bracket 3. Positioning sleeve 304, which is concentrically arranged with the output shaft of motor 2, is fixedly connected to the connecting plate by screws. Positioning sleeve 304 can be a nylon sleeve.

[0034] The mounting bracket 3 has two fixing plates welded to its inner wall, which fix the two ends of the guide rod 302. The length direction of the guide rod 302 is parallel to the sliding direction of the side plate 5. Furthermore, the sliding directions of the mounting plate 4 and the side plate 5 are parallel to each other.

[0035] like Figure 6 and 8 As shown, the side of the mounting plate 4 is connected to the telescopic end of the electric push rod 301. The electric push rod 301 drives the mounting plate 4 to move in position. The mounting plate 4 is fixedly connected to a clamping block 401, and the clamping block 401 has a clamping groove 402 for placing the R-type pin.

[0036] The clamping groove 402 includes a circular recess 408 that mates with the head of the R-type pin 6, and a rectangular recess 409 that communicates with the circular recess 408. During installation, the head of the R-type pin 6 is inserted into the circular recess 408, and the two pin legs of the R-type pin 6 are pressed together and inserted into the rectangular recess 409. Thus, the R-type pin 6 is clamped in the clamping groove 402 by its own elasticity, and the pin legs of the R-type pin 6 extend out of the rectangular recess 409 to ensure subsequent insertion into the pin hole.

[0037] like Figure 5 As shown, the side plate 5 is welded with a guide plate 501, a strip plate 502, and a positioning ball 503 corresponding to the position of the clamping groove 402, which is fixedly connected by a connecting plate. The guide plate 501 has a through hole that mates with the guide rod 302, and the guide rod 302 is fitted with a spring 306. The spring 306 is located below the guide plate 501 and is used to push the guide plate 501 upward by the spring 306, thereby pushing the positioning ball 503 toward the clamping block 401, so that the positioning ball 503 can be kept in a position close to the clamping block 401.

[0038] like Figure 8 and 9 As shown, when the R-type pin 6 needs to be installed, first insert the R-type pin 6 into the clamping groove 402, and then lift the mounting box 1 to the wire clamp position using the linker. The mounting frame 3 is welded with a vertically arranged support plate 307 with a positioning sleeve 304, and the support plate 307 has a positioning slot 308. The positioning slot 308 cooperates with the bolts or pins on the wire clamp to achieve preliminary positioning.

[0039] Then, by adjusting the position, the positioning sleeve 304 is fitted onto the end of the bolt or pin. At this time, the positioning ball 503 is squeezed by the bolt or pin, causing the positioning ball 503 to move away from the clamping block 401. The distance between them increases, thereby causing the side plate 5 to drive the strip plate 502 to move. At this time, the strip plate 502 does not trigger the photoelectric sensor 303. Furthermore, the movement of the side plate 5 causes the guide plate 501 to move along the guide rod 302 and compress the spring 306. Thus, under the action of the spring 306, the positioning ball 503 is always kept in close contact with the circumferential surface of the bolt or pin.

[0040] After the positioning sleeve 304 is fitted onto the end of the bolt or pin, the motor 2 is started. The motor 2 drives the mounting frame 3 to rotate as a whole. When the positioning sleeve 304 cooperates with the end of the bolt or pin, the positioning ball 503 and the clamping block 401 rotate around the bolt or pin when the motor 2 drives the mounting frame 3 to rotate.

[0041] Furthermore, when the positioning ball 503 corresponds to the pin hole position of the bolt or pin shaft, the positioning ball 503 is inserted into the pin hole port position under the push of the spring 306. At this time, the position of the side plate 5 moves, which in turn causes the position of the strip plate 502 to change. At this time, the photoelectric sensor 303 is triggered by the strip plate 502 to accurately determine the pin hole position. After receiving feedback information, it indicates that the pin hole position is determined. At this time, the mounting plate 4 is moved by the electric push rod 301, which causes the clamping block 401 to move in the direction of the bolt or pin shaft, so that the R-type pin 6 is inserted into the pin hole.

[0042] Therefore, by driving the mounting bracket 3 to rotate via the motor 2, the positioning ball 503 and the clamping block 401 rotate along the bolt or pin shaft, thereby quickly determining the pin hole position and simplifying the pin hole position determination process. Furthermore, by using the strip plate 502 to trigger the photoelectric sensor 3, the pin hole position can be further accurately determined, making the overall positioning process simpler and more accurate, and effectively improving the overall flexibility and convenience of use.

[0043] Example 2

[0044] Based on Example 1, such as Figure 4 and 7 As shown, the mounting plate 4 is fixed to the U-shaped plate 403 by screws or welding, and two guide rods 404 are fixedly connected between the two side walls of the U-shaped plate 403. The guide rods 404 are arranged parallel to the positioning sleeve 304 and are fitted with compression springs 405.

[0045] The clamping block 401 has a through hole that fits with the guide rod 404 with a clearance. The compression spring 405 presses one side of the clamping block 401 so that the clamping block 401 remains in position corresponding to the positioning ball 503.

[0046] like Figure 9 As shown, the clamping block 401 has a wedge-shaped part 406 on its side, and a stop bar 305 is fixedly connected between the two side walls of the mounting bracket 3. When the mounting plate 4 drives the clamping block 401 to insert the R-type pin 6 into the pin hole, and the electric push rod 301 continues to drive the mounting plate 4 to move, the stop bar 305 cooperates with the wedge-shaped part 406 to make the clamping block 401 move axially along the guide rod 404. That is, as the clamping block 401 gradually approaches and moves along the bolt or pin shaft, it moves axially along the bolt or pin shaft simultaneously.

[0047] At this point, the R-pin 6 has been inserted into the pin hole, preventing the R-pin 6 from moving axially along the bolt or pin shaft with the clamping block 401, thereby causing the R-pin 6 to disengage from the clamping groove 402, thus completing the installation of the R-pin 6.

[0048] Example 3

[0049] Based on Example 2, such as Figure 6 and 9 As shown, the clamping block 401 is fixedly connected to an arc-shaped pressure plate 407. The arc-shaped pressure plate 407 is located above the circular recess 408, and the inner surface of the arc-shaped pressure plate 407 is flush with the upper edge of the circular recess 408. This allows the R-type pin 6 to continue to be pushed by the arc-shaped pressure plate 407 after it is disengaged from the clamping groove 402, as the clamping block 401 moves, thus ensuring that the R-type pin 6 can be inserted into the pin hole.

[0050] Meanwhile, the positioning sleeve 304 is provided with fan-shaped slots 309 corresponding to the positions of the positioning ball 503 and the clamping block 401. The fan-shaped slots 309 can avoid interference with the clamping block 401 or the positioning ball 503, thereby improving the reliability of use.
