Detailed Description
In one embodiment shown in fig. 2, the disconnecting switch contact finger assembling device comprises two pressure plates 100, a first adjusting block 200, a second adjusting block 300 and an adjusting screw 400;
the two pressing plates 100 are arranged in parallel, the first adjusting block 200 and the second adjusting block 300 are arranged in parallel and transversely arranged between the two pressing plates 100, both ends of the first adjusting block 200 and the second adjusting block 300 are hinged with the connecting rod 500, the other end of the connecting rod 500 is hinged with the pressing plate 100 on the corresponding side, and the connecting rod 500 is positioned between the first adjusting block 200 and the second adjusting block 300, namely, the included angle between the first adjusting block 200 and the connecting rod 500 and the included angle between the second adjusting block 300 and the connecting rod 500 are arranged in an opposite direction;
the adjusting screw 400 vertically penetrates through the first adjusting block 200 and then is in threaded connection with the second adjusting block 300, and the adjusting screw 400 is axially fixed and rotatably connected with the first adjusting block 200.
As shown in fig. 3 and 4, when the disconnecting switch finger assembling device is used, the adjusting screw 400 is rotated, and the adjusting screw 400 is rotated, so that the adjusting screw 400 can only rotate relative to the first adjusting block 200 and can not move axially. Therefore, the second adjusting block 300 will move closer to the first adjusting block 200 along the thread of the adjusting screw 400, and along with the movement of the second adjusting block 300, the included angle between the second adjusting block 300 and the connecting rod 500 hinged thereto becomes larger gradually, so as to gradually spread the two pressing plates 100. Meanwhile, the first adjusting block 200 is linked therewith and moves closer to the second adjusting block 300, the included angle between the first adjusting block 200 and the connecting rod 500 hinged with the first adjusting block is gradually increased, and the isolating switch contact finger assembling device enters a spreading state.
As shown in fig. 5, the adjusting screw 400 is provided with a rotation limiting groove, and the first adjusting block 200 is rotatably connected in the limiting groove. Through setting up the spacing groove on adjusting screw 400, first regulating block 200 rotates to be connected at the spacing inslot to make adjusting screw 400 can rotate relative to first regulating block 200, but can not axial motion.
Further, the adjusting screw 400 comprises a rod body 410 and a shaft sleeve 420, the rod body 410 comprises a thick rod section 411 and a thin rod section 412, the shaft sleeve 420 is sleeved on the thin rod section 412, the shaft sleeve 420 is fixedly connected with the thin rod section 412 through a pin 430, and a rotation limiting groove is formed between the shaft sleeve 420 and the thick rod section 411.
During the assembly of the first adjustment block 200 to the adjustment screw 400, the first adjustment block 200 is first mounted to the upper thin rod section 412, and then the bushing 420 is mounted to the thin rod section 412, and the first adjustment block 200 is fixed between the bushing 420 and the thick rod section 411. Finally, the pin 430 is inserted into the pin hole at the end of the rod section 412 to fix the bushing 420 and the rod section 412 together. The sleeve 420 and the rod segment 412 may be secured together by other means, such as by a threaded connection.
As shown in fig. 1, a guide device 600 is further disposed between the two pressure plates 100, the guide device 600 includes a guide sleeve 610 and a guide rod 620, the guide sleeve 610 spans the two pressure plates 100, two ends of the guide sleeve 610 are respectively fixedly connected with the corresponding pressure plates 100, the middle portion of the guide sleeve 610 is a cross section, and the guide rod 620 is inserted into the guide sleeve 610.
In the process of the expansion and contraction of the two pressing plates 100, the movement tracks of the two pressing plates 100 are all in the axial direction of the guide rod 620, so that the two pressing plates 100 are expanded stably and parallelly, the situation of dislocation is avoided, and the stability and reliability of the whole device are improved.
In the process of shrinking the two pressing plates 100, when the guide sleeves 610 are drawn together toward the middle, the guide sleeves 610 at the two ends of the cross section are pressed against each other when the width of the cross section becomes zero, the shrinkage reaches the limit position, and the adjusting screw 400 cannot rotate at this time. The width of the cross section is preferably matched with the length of the thread of the adjusting screw 400, so that the second adjusting block 300 is prevented from being separated from the thread part of the adjusting screw 400.
Further, as shown in fig. 6, one end of the guide rod 620 is provided with a limit baffle 621, the other end is provided with a limit pin hole 622, a limit pin 623 is inserted into the limit pin hole 622, and the guide sleeve 610 is located between the limit baffle 621 and the limit pin 623.
In the process of opening the two pressing plates 100, the guide sleeve 610 is located in the interval formed by the limit baffle 621 and the limit pin 623, and when the two ends of the guide sleeve 610 move to touch the limit baffle 621 and the limit pin 623, the adjusting screw 400 cannot rotate continuously at the moment, so that the opening distance of the pressing plates 100 is limited.
The guide rod 620 is fixed by the aid of the limiting pin 623, assembly of the guide rod 620 and the guide sleeve 610 is facilitated, the guide rod 620 is inserted into the guide sleeve 610 and then fixed by the limiting pin 623, and assembly efficiency is improved.
Further, a rotating handle 440 is disposed on the adjusting screw 400 at the end away from the screw thread. Through setting up twist grip 440, reduce the rotation dynamics by a wide margin.
As shown in fig. 7, in the schematic use diagram of the disconnecting switch contact finger assembling device, after the disconnecting switch contact finger assembling device is placed in the high-voltage disconnecting switch contact finger 100a, the rotating handle 440 is rotated to prop the contact finger 110a to a certain distance, the contact finger frame 200a is assembled, the rotating handle 440 is rotated reversely, the two pressing plates 100 are retracted and returned, and the disconnecting switch contact finger assembling device is taken out.
Of course, the present invention is not limited to the above-mentioned embodiments, and those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention, and such equivalent modifications or substitutions are included in the scope defined by the claims of the present application.
