[0028] In this embodiment, the height of the transmission line is adjusted by driving the rotating disk 200 to rotate, thereby driving the height of the threaded rod 300 to adjust; and after the height adjustment of the transmission line is completed, the limiting assembly 400 is clamped in the limiting groove 201 of the rotating disk 200 to limit the rotating disk 200 to prevent the transmission line from shaking. The above height adjustment method is convenient and quick to operate, and is convenient for adjusting the height of the transmission line.
[0029] In one embodiment, see Figure 1As shown, the limiting component 400 includes a limiting member 410 and a first elastic member 420, the first end of the first elastic member 420 is connected to the reset component 500, the second end of the first elastic member 420 is connected to the limiting member 410, and the limiting member 410 is used to be inserted into the limiting groove 201 under the elastic force of the first elastic member 420. In this embodiment, the limit assembly 400 adopts a structure in which a limit member 410 is connected to a first elastic member 420, so that when the first elastic member 420 is compressed, the limit member 410 moves in a direction away from the turntable 200 to make way for the turntable 200, thereby facilitating the smooth rotation of the turntable 200, and under the elastic action of the first elastic member 420, the limit member 410 moves in a direction close to the turntable 200, so that the limit member 410 is inserted into any limit groove 201 of the turntable 200, thereby limiting the continued rotation of the turntable 200, thereby achieving the fixation of the threaded rod 300 and the transmission line connected to the end of the threaded rod 300 at a certain height position.
[0030] In one embodiment, continue to refer to Figure 1 As shown, the end face of the limiting member 410 close to the limiting groove 201 is set as an inclined surface, and the inclined surface is gradually inclined from the side close to the turntable 200 to the side away from the turntable 200 toward the direction of the end of the threaded rod 300 away from the frame 100. When the rotating disk 200 stops rotating and the limiting groove 201 on the rotating disk 200 is aligned with the limiting groove 201, the limiting groove 410 is reset under the elastic force of the first elastic groove 420, and the limiting groove 201 on the rotating disk 200 is driven to move to the side close to the rotating disk 200, so that the limiting groove 201 on the rotating disk 200 is inserted into the limiting groove 201 of the rotating disk 200.
[0031] In one embodiment, the first elastic member 420 adopts a compression spring structure, wherein the limiting assembly 400 further includes a mounting seat 430, the mounting seat 430 is provided with a mounting slot, the first elastic member 420 and the limiting member 410 are installed in the mounting slot, the first end of the first elastic member 420 is fixed in the mounting slot, and the second end of the first elastic member 420 is connected to the limiting member 410. When the rotating disk 200 abuts against the inclined surface of the limiting member 410 and the rotating disk 200 is driven to rotate, the limiting member 410 is driven to move to the side away from the rotating disk 200, and the first elastic member 420 is compressed; the limiting member 410 gives way to the rotating disk 200, so that the rotating disk 200 rotates smoothly; when the rotating disk stops rotating and the limiting slot 201 is aligned with the limiting member 410, the limiting member 410 moves toward the side close to the rotating disk 200 under the action of the elastic force of the first elastic member 420, thereby driving the limiting assembly 400 to insert into the limiting slot 201.
[0032] In other embodiments, the first elastic member 420 may also adopt a torsion spring, a disc compression spring or other structures, which are not listed herein.
[0033] In one embodiment, see Figure 1 As shown, it also includes a reset component 500, which includes a connecting member 510 and an operating member 520. The middle part of the connecting member 510 is rotatably arranged on the frame 100 through a rotating shaft. The first end of the connecting member 510 is fixedly connected to the limiting component 400. Specifically, the first end of the connecting member 510 is fixedly connected to the mounting seat 430 of the limiting component 400, and the second end of the connecting member 510 is connected to the operating member 520. The connecting member 510 is used to rotate relatively around the rotating shaft under the drive of the operating member 520, so as to drive the limiting component 400 to disengage from the limiting groove 201.
[0034] In this embodiment, a reset assembly 500 is provided. By operating the operating member 520 of the reset assembly 500, the connecting member 520 can be driven to rotate around the rotating shaft, thereby driving the limiting assembly 400 to move in a direction away from the limiting groove 201 of the turntable 200, thereby realizing the separation of the limiting assembly 400 from the limiting groove 201 of the turntable 200; this operation method is simple and convenient.
[0035] In one embodiment, the reset assembly 500 also includes a second elastic member 530, the first end of the second elastic member 530 is connected to the frame 100, the second end of the second elastic member 530 is connected to the connecting member 510, and the second elastic member 530 is used to apply elastic force to the connecting member 510 to drive the first end of the connecting member 510 to move toward the direction of the limiting groove 201.
[0036] In one embodiment, the second elastic member 530 adopts a compression spring structure, wherein a receiving groove is provided on the frame 100, and the receiving groove is used for installing the compression spring, and the compression spring is installed at the second end of the connecting member 510 and is located on the other side opposite to the operating member 520. When the operating member 520 is applied with force, the second end of the connecting member 510 is driven to overcome the elastic force of the second elastic member 530 and move toward the side where the second elastic member 530 is located, so that the first end of the connecting member 510 moves in the direction opposite to the second end, that is, away from the second elastic member 530, thereby realizing the overall movement of the limiting assembly 400 and disengaging from the limiting groove 201 of the rotating disk 200; when the force applied to the operating member 520 is canceled, the second end of the connecting member 510 moves toward the side close to the operating member 520 under the action of the elastic force, thereby causing the limiting assembly 400 to abut against the limiting groove 201 again.
[0037] In other embodiments, the second elastic member 530 may also adopt a torsion spring, a disc compression spring or other structures, which are not listed herein.
[0038] In one embodiment, the operating member 520 is a pressing rod. In this embodiment, the operating member 520 adopts a pressing rod structure, which is convenient for operators to adjust the height of the power transmission line by operating the pressing member.
[0039] In one embodiment, the operating member 520 at least partially protrudes from the frame 100. Further, in order to facilitate the operation of the operating member 520, the operating member 520 is designed to at least partially protrude from the frame 100.
[0040] In one embodiment, continue to refer to Figure 1 As shown, the second end of the connecting member 510 is formed with an abutting surface that abuts against the second elastic member 530, and the abutting surface gradually approaches the second elastic member 530 from the second end to the first end of the connecting member 510. In this embodiment, the abutting surface of the second end of the connecting member 510 is set as an inclined surface, so that when the operating member 520 drives the second end of the connecting member 510 to move toward the side close to the second elastic member 530, the abutting surface of the connecting member 510 abuts against the second elastic member 530, and drives the second elastic member 530 to contract along the inclined surface, and then the first end of the connecting member 510 drives the limiting assembly 400 to move in a direction away from the rotating disk 200, so that the limiting assembly 400 is separated from the limiting groove 200; when the force applied to the operating member 520 is canceled, the connecting member 510 is reset under the elastic force of the second elastic member 530, and moves in a direction close to the rotating disk 200.
[0041] In one embodiment, see Figure 1 and Figure 3As shown, one end of the threaded rod 300 away from the turntable 200 is connected to the contact network through a connecting assembly 600, and the connecting assembly 600 includes a fixing seat 610 and a connecting head 620. The fixing seat 610 is provided with a fixing groove 601, and a third elastic member 630, a fourth elastic member 640 and a connecting head 620 are installed in the fixing groove. The first end of the third elastic member 630 is connected to the bottom of the fixing groove 601, the second end of the third elastic member 630 is connected to the connecting head 620, the first end of the fourth elastic member 640 is connected to the side wall of the fixing groove 601, and the second end of the fourth elastic member 640 is connected to the connecting head 620. The elastic force directions of the third elastic member 630 and the fourth elastic member 640 are opposite, and the connecting head 620 at least partially extends outside the fixing groove 601. In this embodiment, the threaded rod 300 is connected to the contact network through the connecting assembly 600, and the directions of the forces of the third elastic member 630 and the fourth elastic member 640 of the connecting assembly 600 are relatively set, so that when the movement of the train causes the transmission line to shake, and then causes the connecting head 620 to shake accordingly, the forces of the third elastic member 630 and the fourth elastic member 640 in the relative directions can stabilize the connecting head 620 more quickly, and the connecting head 620 is movably installed in the fixing groove 601 of the fixing seat 610 to prevent the problem of the connecting head 620 bending due to line shaking.
[0042] In one embodiment, continue to refer to Figure 1 and Figure 3 As shown, the end of the threaded rod 300 away from the turntable 200 is fixedly connected with a moving rod 310, and the moving rod 310 is connected to the fixed seat 610 through a bearing. The frame includes a top plate 110 and a wing portion 120 arranged around the top plate 110 in the circumferential direction. A cavity is formed between the top plate 110 and the wing portion 120. The threaded hole is opened in the top plate 110, and a part of the threaded rod 300 is penetrated in the cavity. The outer edge of the moving rod 310 away from the bearing is in sliding contact with the wing portion 120. In this embodiment, the frame 100 adopts the structure of the top plate 110 and the wing portion 120, and the moving rod 310 slides on the wing portion 120, which can ensure the stability of the connection component 600 moving along the axial direction of the threaded rod 300.
[0043] In one embodiment, the side wing portion 120 has a limiting plate 130 extending into the cavity at one end away from the top plate 110, and a limiting channel is formed on the inner side of the limiting plate 130. The width of the limiting channel is smaller than the length of the moving rod 310. In this way, the moving distance of the moving rod 310 is abutted by the limiting plate 130 to prevent the moving rod 310 from detaching from the frame 100.
[0044] During the running of the train, the overhead contact network is erected above the railway line to supply power to the train, and the transmission line is suspended through the overhead contact network suspension connector. The specific working process of this overhead contact network suspension connector is as follows:
[0045] By pressing the operating member 520 in a direction close to the frame 100, the second end of the connecting member 510 is driven to rotate in a direction close to the second elastic member 530, thereby driving the limiting assembly 400 connected to the first end of the connecting member 510 away from the turntable 200, so that the limiting member 410 is disengaged from the limiting groove 201, so that the turntable 200 can be rotated. Through the rotation of the turntable 200, the threaded rod 300 can be driven to rotate to move along the axial direction of the threaded rod 300 relative to the frame 100, thereby realizing the adjustment of the height of the transmission line connected to the connecting assembly 600.
[0046] After the height adjustment of the transmission line is completed, the turntable 200 is moved along the length direction of the frame. When the turntable 200 moves to the position of the limit assembly 400, the turntable 200 first abuts against the inclined surface of the limit member 410, and squeezes the limit member 410 along the inclined surface of the limit member 410, so that the limit member 410 compresses the first elastic member 420, and the limit member 410 moves away from the turntable 200. When the limit groove 201 of the turntable 200 is aligned with the limit member 410, the limit member 410 approaches the turntable 200 under the elastic force of the first elastic member 420, and is clamped in the limit groove 201, so as to limit the turntable 200, so as to prevent the threaded rod 300 from rotating due to the shaking of the transmission line, thereby affecting the height change of the transmission line.
[0047] In addition, when the transmission line shakes due to the movement of the train, the relative forces of the third elastic member 630 and the fourth elastic member 640 of the connecting assembly 600 can reduce the shaking amplitude of the connecting head 620 and ensure the stability of the connection.
[0048] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0049] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
