Description

Technical Field

[0001] The utility model relates to the technical field of electric power fittings equipment, in particular to a quick opening device for an R-type locking pin of a bowl head hanger plate. Background Technique

[0002] The R-type locking pin of the bowl head hanger plate is a locking device with a special design and plays a crucial role in the transmission line. Its main function is to ensure the stable connection between the insulator string and the bowl head hanger plate and prevent falling off due to factors such as vibration and wind force. Therefore, to further improve the safety and reliability of the transmission line, it is crucial to ensure the locking force and position accuracy requirements of the R-type locking pin between the insulator string and the bowl head hanger plate.

[0003] Regarding the above problems, the invention patent document with the application number CN107009319A discloses a split pin press-fitting tool, which includes a pressing head. A press-fitting hole is axially opened at the first end of the pressing head, and a plurality of mounting holes are radially opened on the pressing head. The mounting holes are all communicated with the press-fitting hole; steel balls and compression springs are arranged in the mounting holes. The steel balls are located at one end of the mounting hole close to the press-fitting hole. One end of the compression spring is fixedly connected with the steel ball, and the other end is fixedly connected with the side wall of the mounting hole at the end far from the press-fitting hole. When the above technology is used, the split pin is inserted into the press-fitting hole. At this time, the steel ball is subjected to the pressure from the split pin and transmits this force to the compression spring. The compression spring is stressed and pulls the steel ball back into the mounting hole. The steel ball clamps the split pin with the pressure of the compression spring. Then, the pressing head is operated to align the split pin with the relevant hole and insert the split pin. Since the clamping force of the steel ball on the split pin is not very large, after the split pin is inserted into the relevant hole, the pressing head can be pulled out, and the split pin remains in the relevant hole.

[0004] The above split pin press-fitting tool completes the press-fitting of the split pin through the cooperation of the compression spring and the steel ball, but there are still certain deficiencies in its use: when the lower end surface of the part to be processed is uneven, due to the lack of a positioning reference for this tooling, it is difficult to ensure the installation position accuracy of the split pin. At the same time, since the clamping force of the steel ball on the split pin is not very large, it is difficult to ensure the locking effect of the split pin. Content of the Utility Model

Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0035] Next, the principles and spirits of the present invention will be elaborated in detail with reference to several representative embodiments of the present invention.

[0036] As Figures 1 to 4 shown, a quick-opening device for the R-type locking pin of a bowl head hanging plate 13 provided by the present invention includes a workbench 1, a stamping assembly, and a limiting assembly.

[0037] Among them, there are at least two groups of parallel table legs under the workbench 1, and a support rod 8 is fixedly connected between the table legs, and the upper surface of the workbench 1 is horizontal.

[0038] The described stamping assembly is fixedly connected to the left part of the upper surface of the workbench 1 and is used for stamping the R-type locking pin inserted into the bowl head hanging plate 13. The stamping assembly includes a horizontally placed cylinder 2. The cylinder 2 is preferably a heavy-duty cylinder and is clamped and fixed with angle steel and bolts to ensure the stability of the cylinder 2.

[0039] Among them, the control signal input end of the cylinder 2 is connected to the controller 6 through the control circuit 7, and the control signal sent by the controller 6 is transmitted to the control signal input end of the cylinder 2 through the control circuit 7; in this embodiment, the controller 6 can adopt a pedal, and the pedal is located below the workbench 1 on the side where the limiting assembly is placed, which is convenient for the staff to operate. Preferably, the control circuit 7 can adopt a wire.

[0040] The output end of the cylinder 2 is coaxially provided with a punch rod 4, and the right end of the punch rod 4 is coaxially provided with a punch head 10. Preferably, a stamping part is integrally provided at the right end of the punch head 10, and the stamping part is adapted to the shape of the open end of the R-type locking pin.

[0041] In this embodiment, the stamping part is a frustum with an outer diameter gradually decreasing from left to right, such as a quadrangular frustum, a conical frustum, etc. The stamping part is preferably a trapezoidal block. Guide grooves 20 for guiding the R-shaped locking pins are provided on the front and rear sides of the stamping part. Each guide groove 20 is horizontally arranged in the left-right direction. The left end of the inner bottom of the guide groove 20 is inclined outward to form an outward expansion guide for the open end of the R-shaped locking pin, ensuring that after the R-shaped locking pin is horizontally limited by the guide groove 20, the open end of the R-shaped locking pin can smoothly enter the front and rear sides of the stamping part for outward expansion.

[0042] In this embodiment, the horizontally arranged guide groove 20 can effectively prevent the R-shaped locking pin from shifting when inserted into the tail end of the bowl head hanger 13, guide the R-shaped locking pin to be inserted correctly and smoothly, and cooperate with the shape of the stamping part to ensure the stamping quality.

[0043] Preferably, the output end of the cylinder 2 is provided with a guide sleeve 3. A punch rod 4 is arranged through the inside of the guide sleeve 3. The guide sleeve 3 is used to guide and support the punch rod 4 to ensure the stability and accuracy of the punch rod 4 during movement.

[0044] Furthermore, a punch head 10 connecting part is added to the right end of the punch rod 4. The punch head 10 is detachably connected to the right end of the punch rod 4 through the punch head 10 connecting part; during use, the punch head 10 is a vulnerable part and needs to be replaced regularly according to the wear condition. The setting of the punch head 10 connecting part can improve the replacement efficiency of the punch head 10 and reduce the working intensity. In this embodiment, the punch head 10 connecting part can adopt a threaded connecting sleeve, and the punch rod 4 and the punch head 10 at both ends are respectively connected by threads; the punch head 10 connecting part can also adopt a connecting plate 11, and the punch rod 4 and the punch head 10 at both ends are respectively connected by bolts.

[0045] Preferably, a wear-resistant layer is provided on the end face of the punch head 10. The wear-resistant layer can adopt a coating composed of hard chromium, which can effectively extend the service life of the punch head 10.

[0046] The described limiting component is arranged on the upper right part of the workbench 1. It limits the position of the bowl head hanger 13 during the assembly process of the R-shaped locking pin, preventing the bowl head hanger 13 from shifting when the punch head 10 is pushed into the R-shaped locking pin, resulting in assembly failure.

[0047] In the present utility model, the limiting assembly includes a vertical limiting device and a horizontal limiting device. The vertical limiting device is arranged on the lower side of the bowl head hanger plate 13. At the contact position between the upper end face of the vertical limiting device and the bowl head hanger plate 13, a first groove 21 adapted to the shape of the bottom end of the bowl head hanger plate 13 is provided. The vertical limiting device is used to support the bottom of the bowl head hanger plate 13 vertically. The horizontal limiting device is arranged on the right side of the bowl head hanger plate 13. At the contact position between the left end face of the horizontal limiting device and the bowl head hanger plate 13, a second groove 22 adapted to the shape of the right end of the bowl head hanger plate 13 is provided. The horizontal limiting device is used to support the right end of the bowl head hanger plate 13 horizontally. During the assembly process, the vertical limiting device and the horizontal limiting device act together to limit the bowl head hanger plate 13, preventing the bowl head hanger plate 13 from displacing when the punch 10 is pushed into the R-type locking pin, and ensuring the smooth progress of the assembly work.

[0048] In this embodiment, the vertical limiting device can adopt a support block 14, and the first groove 21 is arranged on the upper end face of the support block 14.

[0049] The horizontal limiting device can adopt a limiting post 17, and the second groove 22 is arranged on the left end face of the limiting post 17.

[0050] In the present utility model, a vertical height adjustment device is further arranged between the vertical limiting device and the workbench 1. The height adjustment mechanism is used to adjust the horizontal height of the vertical limiting device. The height adjustment mechanism can adopt a lead screw 18 lifting mechanism connected to the vertical limiting device, that is, the threaded rod is threadedly connected to the vertical limiting device, and the vertical limiting device is restricted to move up and down only with the rotation of the threaded rod by arranging a guide rod, and the thread is used to perform the position locking function. The above lead screw 18 lifting mechanism belongs to the conventional technology in the field and will not be elaborated here.

[0051] In this embodiment, the vertical height adjustment device can also adopt a cushion block 9, which is replaced according to the models of different bowl head hanger plates 13. The cushion block 9 is arranged between the support block 14 and the workbench 1 to adjust the height of the bowl head hanger plate 13, ensuring that the horizontal height of the punch 10 is consistent with the pin hole opening of the bowl head hanger plate 13, and avoiding the situation that the punch 10 cannot enter the pin hole opening during the stamping process.

[0052] In this embodiment, a horizontal position adjustment device is further provided at the right end of the horizontal limiting device. The horizontal position adjustment device is used to adjust the left and right positions of the horizontal limiting device. The horizontal position adjustment device can adopt a lead screw 18 and a positioning plate 19 connected to the horizontal limiting device. The lead screw 18 is threadedly connected to the positioning plate 19 through a threaded hole provided on the positioning plate 19. The left end of the lead screw 18 is detachably connected to the right end of the horizontal limiting device. During use, by rotating the lead screw 18, the left end of the lead screw 18 moves. After reaching the set position, through the lock nut 16 provided on the lead screw 18 on the right side of the positioning plate 19, the position of the lead screw 18 is locked after the position adjustment is in place. Subsequently, the horizontal limiting device is installed at the left end of the lead screw 18, and the adjustment of the horizontal limiting device can be completed. Subsequently, the right end of the bowl head hanger plate 13 can be effectively supported by using the horizontal limiting device.

[0053] The combined use of the horizontal limiting device and the horizontal position adjustment device can be applicable to the assembly of the R-type locking pins of bowl head hanger plates 13 of different specifications, that is, the horizontal limiting device can be assembled after the position of the left end of the lead screw 18 is adjusted in place. The detachable connection mode of the lead screw 18 and the horizontal limiting device facilitates the maintenance and replacement of the horizontal limiting device.

[0054] Considering that after the R-type locking pin is assembled in place with the bowl head hanger plate 13, the head (i.e., the non-open end) of the R-type locking pin will protrude from the body of the bowl head hanger plate 13. In order to reduce the influence of the horizontal limiting device on the movement path of the head of the R-type locking pin, in this embodiment, an accommodating groove 23 for the head of the R-type locking pin is further provided in the second groove 22, which can also play a role in limiting the position of the head of the R-type locking pin.

[0055] In order to further ensure that the horizontal height of the punch 10 and the horizontal limiting device remains unchanged during movement, a guiding device 12 is further provided outside the limiting assembly in this embodiment. Punch guiding grooves and horizontal limiting device guiding grooves are correspondingly provided on the left and right sides of the guiding device 12. The punch 10 and the horizontal limiting device are respectively slidably connected to the guiding device 12 through the punch guiding grooves and the horizontal limiting device guiding grooves. The shapes of the punch guiding grooves and the horizontal limiting device guiding grooves are adapted to the punch 10 and the horizontal limiting device.

[0056] According to the above description of this specification, those skilled in the art can also understand the following terms used, such as the terms indicating the orientation or position relationship, such as "upper", "lower", "front", "rear", "left", "right", "width", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or position relationship shown in the drawings of this specification. It is only for the purpose of facilitating the description of the solution of the present invention and simplifying the description, rather than explicitly or implicitly indicating that the device or element involved must have the specific orientation and be constructed and operated in the specific orientation. Therefore, the above terms indicating the orientation or position relationship cannot be understood or interpreted as a limitation to the solution of the present invention.

[0057] In addition, in the description of this specification, the meaning of "a plurality of" is at least two, such as two, three or more, etc., unless otherwise specifically defined.
