[0028] Embodiment 1

[0029] In this embodiment, refer to Figures 1 to 4As shown, a contact network suspension string support is provided, including: a first suspension rope 100, a second suspension rope 200, and a connecting rope 300 connected between the first suspension rope 100 and the second suspension rope 200, wherein the first end of the connecting rope 300 is connected to the first suspension rope 100 through a locking mechanism 400, and the second end of the connecting rope 300 is connected to the second suspension rope 200 through a locking mechanism 400; thus, by operating the locking mechanism 400, the two ends of the connecting rope 300 can be quickly disassembled from the first suspension rope 100 and the second suspension rope 200, respectively, and the installation or disassembly of the connecting rope 300 can be achieved. In this embodiment, one end of the connecting rope 300 is connected to the first suspension rope 100 through a locking mechanism as an example for description. Among them, refer to Figure 2 As shown, the locking mechanism 400 includes a fixing seat 410, a positioning member 420 and a clamping member 430. The fixing seat 410 is fixedly installed on the end of the first suspension rope 100; the fixing seat 410 is provided with a positioning hole 401, and the side wall of the positioning hole 401 is provided with a clamping hole 402. The positioning member 420 is movably arranged in the positioning hole 401 along the opening direction of the positioning hole 401, and the clamping member 430 is movably arranged in the clamping hole 402 along the opening direction of the clamping hole 402. A clamping groove 421 is provided on one side of the positioning member 420, and the clamping member 430 is used to be movably inserted into the clamping groove 421 when the clamping groove 421 is aligned with the clamping hole 402. The clamping member 430 at least partially protrudes to the end of the clamping hole 402 away from the positioning hole 401, and the end of the positioning member 420 away from the positioning hole 401 is connected to one end of the connecting rope 300.

[0030] In this embodiment, the first lifting rope 100 and the connecting rope 300 are movably connected through the locking mechanism 400; and the second lifting rope 200 and the connecting rope 300 are movably connected, and the locking mechanism 400 adopts a connection method of a fixed base 410, a positioning member 420 and a clamping member 430. The positioning member 420 is passed through the positioning hole 401 of the fixed base 410, and the clamping member 430 is clamped in the clamping groove 421 of the positioning member 420 to fix the positioning member 420, or the clamping member 430 is detached from the clamping groove 421, which can realize the detachment of the positioning member 420 from the fixed base 410, so that the operation of adding connecting ropes 300 of different lengths between the first lifting rope 100 and the second lifting rope 200 is relatively quick and convenient, and the disassembly and assembly of the connecting rope 300 is convenient.

[0031] In one embodiment, continue to refer to Figure 2As shown, the clamping mechanism 400 further includes an elastic member 440, and the clamping member 430 is connected to the fixing seat 410 through the elastic member 440. In this embodiment, the elastic member 440 is connected to the fixing seat 410, and the elastic member 440 can be connected to the side wall of the clamping hole 402. The elastic member 440 is provided so that when the clamping groove 421 is aligned with the clamping hole 402, the clamping member 430 can automatically extend and clamp into the clamping groove 421 under the action of elastic force, so that the positioning member 420 is fixed in the fixing seat 410, thereby realizing the fixed connection between the connecting rope 300 and the first suspension rope.

[0032] In one of the embodiments, the end face of the clamping member 430 close to the positioning member 420 is set as an inclined surface 431, and the inclined surface 431 gradually inclines toward the direction of the end of the clamping hole 402 away from the positioning hole 401 from the end close to the bottom of the positioning hole 401 to the end away from the bottom of the positioning hole 401, and the positioning member 420 is movably abutted against the inclined surface 431 when inserted into the positioning hole 401.

[0033] By setting the inclined surface 431, when the positioning member 420 is inserted into the positioning hole 401, force is applied to the inclined surface 431, so that the inclined surface 431 generates a component force along the extension direction of the clamping hole 402 after the force is applied, thereby causing the clamping member 430 to move along the clamping hole 402 to the outside of the positioning hole 401.

[0034] In one embodiment, see Figure 2 As shown, a limiting groove 403 is defined on the side wall of the engaging hole 402 , and the elastic member 440 is installed in the limiting groove 403 .

[0035] In one embodiment, the elastic member 440 is a compression spring, and the elastic member 440 is sleeved on the outer periphery of the clamping member 430. The fixing seat 410 is provided with a limiting groove 403 for the elastic member 440 to be installed on the side wall of the clamping hole 402, so as to facilitate the installation and fixation of the elastic member 440. In other embodiments, the elastic member 440 may also be a torsion spring, a butterfly spring, etc., which is not limited herein.

[0036] In this embodiment, the end face of the clamping member 430 close to one end of the positioning member 420 is set as an inclined surface 431, so that in the process of inserting the positioning member 420 into the positioning hole 401 of the fixing seat 410, the positioning member 420 abuts against the inclined surface 431 of the clamping member 430, and drives the clamping member 430 along the inclined surface 431 in the direction away from the positioning hole 401. At this time, the elastic member 440 is forced to contract so that the positioning member 420 can continue to be inserted into the positioning hole 401. When the clamping groove 421 of the positioning hole 420 is aligned with the clamping hole 402, the clamping member 430 is reset under the elastic force of the elastic member 440, and moves in the direction close to the positioning hole 401 to be clamped in the clamping groove 421.

[0037] In one embodiment, the positioning hole 401 is opened in a first direction of the fixing seat 410 toward the connecting rope 300, and the clamping hole 402 is opened in a second direction of the fixing seat 410 perpendicular to the first direction. In this embodiment, the positioning hole 401 and the clamping hole 402 are opened in two directions perpendicular to each other on the fixing seat 410, so that the positioning member 420 passing through the fixing seat 410 can be stably fixed in the fixing seat 410 by the force of the clamping member 430, thereby realizing a stable connection between the first suspension rope 100 and the connecting rope 300.

[0038] In one embodiment, the locking mechanism 400 also includes a locking rotating member 450, which is rotatably connected to the fixed base 410 via a rotating shaft. The locking rotating member 450 is used to rotate to align with the clamping member 430 and abut against the end surface of the clamping member 430 away from the positioning member 420.

[0039] In this embodiment, when the locking rotating member 450 rotates to align with the clamping member 430, the locking rotating member 450 abuts against the clamping member 430, limiting the clamping member 430 so that the clamping member 430 cannot be disengaged from the clamping groove 421 of the positioning member 420, thereby ensuring a stable connection between the first suspension rope 100 and the connecting rope 300; when the locking rotating member 450 rotates to other positions, the clamping member 430 can move relative to the positioning hole under the action of the elastic member 440, thereby ensuring that the positioning member is smoothly inserted into the positioning hole 401.

[0040] In one embodiment, see Figure 2 As shown, the locking rotating member 450 is provided with a first clamping structure, and the clamping member 430 is provided with a second clamping structure, and the first clamping structure and the second clamping structure are clamped. In this embodiment, the first clamping structure and the second clamping structure are provided to achieve stable positioning of the clamping member 430.

[0041] In one embodiment, the first clamping structure is a protrusion 451 protruding from the locking rotating member 450, and the second clamping structure is a groove recessed on the end surface of the clamping member 430 away from the positioning member 420, and the protrusion 451 is clamped in the groove;

[0042] In one embodiment, the first clamping structure is a groove recessed on the locking rotating member 450, and the second clamping structure is a convex point protruding from the end surface of the clamping member away from the positioning member, and the convex point is clamped in the groove.

[0043] In this embodiment, the first clamping structure and the second clamping structure are a matching structure of a convex point and a concave groove, which has a simple structure and is convenient for realizing the limit of the clamping member 430 or canceling the limit of the clamping member 430. Of course, in other embodiments, the first clamping mechanism and the second clamping mechanism can also adopt other clamping mechanisms such as mutually clamped buckles and hooks, which are not listed one by one in this article.

[0044] In one embodiment, the material of the protrusion is rubber. When the locking rotating member 450 rotates to align with the clamping member 430, the protrusion is deformed when it abuts against the clamping member 430, and then engages with the groove. At the same time, the protrusion is made of rubber material to avoid collision damage to the clamping member 430.

[0045] During the operation of high-speed rail or EMU, it is necessary to transmit electricity through the contact network, and the contact network needs to be suspended and supported by the contact network suspension string bracket. In order to ensure that the distance between the contact network and the rail surface is consistent throughout the span, the vertical height of the suspension string bracket needs to be adjusted. The adjustment process of this contact network suspension string bracket is as follows:

[0046] According to actual conditions, different lengths of connecting ropes 300 are selected, and the positioning piece 420 connected to the first end of the connecting rope 300 is inserted into the positioning hole 401 of the fixing seat 410 connected to the first suspension rope 100, and the positioning piece 420 connected to the second end of the connecting rope 300 is inserted into the positioning hole 401 of the fixing seat 410 connected to the second suspension rope 200; when the positioning piece 420 abuts against the inclined surface 431 of the clamping piece 430, the positioning piece 420 drives the clamping piece 430 to move in a direction away from the positioning hole 401, and the elastic piece 440 is forced to shrink; when the clamping groove 421 of the positioning piece 420 is aligned with the clamping interface 402, the clamping piece 430 is reset under the elastic force of the elastic piece 440, and is clamped in the clamping groove 421, so that the positioning piece 420 is connected to the fixing seat 410, thereby realizing the connection between the first suspension rope 100 and the connecting rope 300, and the connection between the second suspension rope 200 and the connecting rope 300.

[0047] After the clamping member 430 is clamped in the clamping groove 421, the locking rotating member 450 is rotated so that when the locking rotating member 450 is rotated to align with the clamping member 430, it abuts against the end surface of the clamping member 430 away from the positioning member 420. This can prevent the clamping member 430 from being accidentally moved and causing the first hanging rope 100 and the connecting rope 300, or the second hanging rope 200 and the connecting rope 300 to fall off.

[0048] When it is necessary to separate the connecting rope 300 from the first suspension rope 100 and the second suspension rope 200, the locking rotating member 450 is rotated to disengage the locking rotating member 450 from the snap-in member 430. By pulling the snap-in member 430 in a direction away from the positioning hole 401, the snap-in member 430 can be disengaged from the snap-in groove 421 of the positioning member 420, and then the positioning member 420 is disengaged from the fixing seat 410, thereby achieving the separation of the connecting rope 200 from the first suspension rope 100 and the second suspension rope 200. In this way, connecting ropes 300 of different lengths can be quickly installed or removed between the first suspension rope 100 and the second suspension rope 200 to adjust the length of the contact network suspension string bracket to ensure that the distance between the contact network and the rail surface remains consistent throughout the span.

[0049] In one embodiment, see Figure 1 , Figure 3 to Figure 4 As shown, one end of the first suspension rope 100 away from the connecting rope 300 is connected to the load-bearing cable through a threaded transmission mechanism 500, and the threaded transmission mechanism 500 includes a first crimping member 510 and a second crimping member 520, and the first crimping member 510 and the second crimping member 520 are fixedly connected to the first suspension rope 100 or the second suspension rope 200, and the first crimping member 510 and the second crimping member 520 are respectively clamped on the outer periphery of the load-bearing cable; the threaded transmission mechanism 500 also includes a threaded rod 530 and the mounting member 540, and the mounting member 540 The first crimping member 510 and the second crimping member 520 are fixedly mounted on the first suspension rope 100, and are respectively slidably mounted on the mounting member 540. The threaded rod 530 is rotatably mounted on the mounting member 540. The first crimping member 510 is provided with a first screw hole, and the second crimping member 520 is provided with a second screw hole. The threaded rod 530 is inserted into the first screw hole and the second screw hole, and is threadedly connected to the side wall of the first screw hole and the side wall of the second screw hole. The thread directions of the first screw hole and the second screw hole are opposite. In this way, the first crimping member 510 and the second crimping member 520 can be driven to approach or move away from the load-bearing cable by rotating the threaded rod 530, thereby clamping the load-bearing cable or canceling the clamping effect on the load-bearing cable.

[0050] In this embodiment, an example is given in which the end of the first suspension rope 100 away from the connecting rope 300 is connected to the load-bearing cable through the threaded transmission mechanism 500. Figure 3 and Figure 4 As shown, the threaded transmission mechanism 500 includes a mounting member 540, a threaded rod 530, a first crimping member 510, a second crimping member 520 and a fixing block 550, wherein the mounting member 540 is fixedly connected to the first suspension rope, the mounting member 540 is fixedly connected to the fixing block 550, the fixing block 550 is connected to the threaded rod 530 through a bearing, the first crimping member 510 is provided with a first screw hole, the second crimping member 520 is provided with a second screw hole, the threaded rod 530 is penetrated in the first screw hole and the second screw hole, and is threaded with the side wall of the first screw hole and the side wall of the second screw hole. The first screw hole and the second screw hole have opposite thread directions, and the first crimping component 510 is connected to the first slider 560, and the second crimping component 520 is connected to the second slider 570. The first slider 560 and the second slider 570 are slidably connected to the mounting component 540. The first crimping component 510 and the second crimping component 520 are respectively clamped on the outer periphery of the load-bearing cable. By rotating the threaded rod 530, the first crimping component 510 and the second crimping component 520 are clamped on the load-bearing cable, or the first crimping component 510 and the second crimping component 520 are separated from each other to disengage from the load-bearing cable.

[0051] In one embodiment, continue to refer to Figure 3 and Figure 4 As shown, the first crimping member 510 and the second crimping member 520 are provided with a limiting protrusion 501 for contacting with the load-bearing cable. In this embodiment, the protrusion 501 provided on the first crimping member 510 and the second crimping member 520 increases the friction between the first crimping member 510 and the second crimping member 520 and the load-bearing cable, so that the connection between the first crimping member 510 and the second crimping member 520 and the load-bearing cable is more secure.

[0052] In one embodiment, the end of the second suspension rope away from the connecting rope is connected to the load-bearing rope through a threaded transmission mechanism, the threaded transmission mechanism includes a first crimping piece and a second crimping piece, the first crimping piece and the second crimping piece are fixedly connected to the first suspension rope or the second suspension rope, the first crimping piece and the second crimping piece are respectively clamped on the outer periphery of the load-bearing rope; the threaded transmission mechanism also includes a threaded rod and a mounting piece, the mounting piece is fixedly mounted on the first suspension rope, the first crimping piece and the second crimping piece are respectively slidably arranged on the mounting piece, the threaded rod is rotatably arranged on the mounting piece, the first crimping piece is provided with a first screw hole, the second crimping piece is provided with a second screw hole, the threaded rod is penetrated in the first screw hole and the second screw hole, and is threadedly connected with the side wall of the first screw hole and the side wall of the second screw hole, and the thread directions of the first screw hole and the second screw hole are opposite. In this way, by rotating the threaded rod, the first crimping piece and the second crimping piece can be driven to approach or move away from the load-bearing rope, thereby clamping the load-bearing rope or canceling the clamping effect on the load-bearing rope.

[0053] The specific action process of the screw transmission mechanism 500 is as follows:

[0054] Rotating the threaded rod 530 drives the first crimping component 510 and the second crimping component 520 to separate from each other. When the two are separated from each other to a preset distance, the bearing cable is inserted between the first crimping component 510 and the second crimping component 520, and then the threaded rod 530 is rotated in the opposite direction to drive the first crimping component 510 and the second crimping component 520 to approach each other to clamp on both sides of the bearing cable until the limiting protrusions 501 inside the first crimping component 510 and the second crimping component 520 abut against the bearing cable, thereby completing the installation of the bearing cable and the contact network suspension string bracket.

[0055] 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.
