[0021] Clamping the column in a first direction by the first clamping arm and clamping the column in a second direction by the second clamping arm;

[0022] Releasing the fixation between the rotating plate and the support seat through the limiting member, enabling the rotating plate to rotate relative to the support seat, and adjusting the angle of the mounting plate in the horizontal plane;

[0023] By adjusting the distance from the end of the adjusting jack rod that presses against the supporting part to the adjusting plate, enabling the column to rotate around the axis of the rotating shaft, and adjusting the angle of the mounting plate in the vertical plane to align the mounting hole positions of the mounting position of the mounting plate with the tunnel or the horizontal support frame.

[0024] The railway catenary suspension post tooling and installation method of the present invention have the following beneficial effects compared with the prior art:

[0025] (1) Release the fixation between the rotating plate and the support base through the limiting member, so that the rotating plate rotates relative to the support base, and adjust the angle of the mounting plate in the horizontal plane; adjust the distance from the end of the adjusting ejector rod that presses against the support part to the adjusting plate, so that the column rotates around the axis of the rotating shaft, and adjust the angle of the mounting plate in the vertical plane to align the mounting hole position of the mounting plate with the mounting position of the tunnel or the horizontal support frame, and then fasten it by bolt connection. This alignment method is simple and fast, and can greatly improve the assembly efficiency;

[0026] (2) Compress the first support spring between the support frame and the bottom surface of the support part. The elastic force of the first support spring supports the support frame, avoiding the shaking and impact of the entire clamping assembly during movement caused by workers forgetting to tighten the four adjusting rods after the hanging column installation is completed, and improving the stability and reliability of the device;

[0027] (3) When both groups of the sliding columns are located in the straight section, the two first clamping arms and the top plate form a clamping state; when one group of the sliding columns is located in the straight section and the other group of the sliding columns is located in the inclined section, the two first clamping arms are in an open state, which is convenient for guiding the column into the first clamping arm or taking out the first clamping arm from the column. This clamping method is convenient and fast, and has a good clamping effect, which can improve the assembly efficiency;

[0028] (4) The guide rod is slidably installed on the clamping frame, and one end is connected to the first clamping arm. The other ends of the two guide rods are both connected to the middle block; the first driving member is a hydraulic cylinder. The first driving member includes a first cylinder body and a first telescopic rod. The first cylinder body is connected to the clamping frame. One end of the first telescopic rod is connected to the first cylinder body, and the other end is hinged to the middle block. Through the transfer of the middle block, the first driving member and the guide rod can both be installed on the clamping frame. The first driving member and the guide rod are both on the same side of the middle block, which can reduce the size of the device, make the structure more compact, occupy less volume, and facilitate the flexible layout of the device in a compact space;

[0029] (5) A slide rail parallel to the column is provided on the chassis; the support frame is slidably installed on the slide rail; one end of the third support spring supports on the chassis, and the other end supports below the support frame. The support frame and the hanging column cause the third support spring to be compressed under the action of gravity. When the mounting plate is butted against the mounting position of the tunnel or the horizontal support frame, the third support spring can have a certain buffering effect on the mounting plate, avoiding damage to the tunnel or the horizontal support frame caused by the impact of the mounting plate, and improving the reliability of the installation.

[0051] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0052] Refer to Figure 1-13 As shown, in the first aspect embodiment of the present invention, a catenary suspension post tooling for installing the catenary suspension post 100 is proposed. The catenary suspension post 100 includes a column body 101 and a mounting plate 102. The catenary suspension post tooling includes a support frame 1, a clamping assembly 2, and an adjusting assembly 3, wherein:

[0053] The support frame 1 includes a support framework 11, a support base 12, two rotating shafts 13, two support blocks 14 and a first support spring 15. The two opposite ends of the support base 12 are respectively rotatably mounted on the support framework 11 through the two rotating shafts 13. A bearing 16 is mounted on the support framework 11, and the rotating shaft 13 is mounted in the bearing 16. The support base 12 is fixedly mounted on the rotating shaft 13. The support block 14 is fixedly mounted on the rotating shaft 13. Support portions 141 are respectively arranged on the two sides of the support block 14 in the horizontal direction. The top surface of the support block 14 is parallel to the top surface of the support base 12. The support block 14 and the support base 12 are respectively located on both sides of the bearing 16. The support portions 141 are arranged on the top surface of the support block 14. An opening is provided on the support base 12 to form an avoidance area. The first support spring 15 is compressed between the support framework 11 and the bottom surface of the support portion 141, and one first support spring 15 is arranged at the bottom of each support portion 141. The first support spring 15 can be a rectangular spring, also known as a die spring. Since the cross-section of the manufacturing material is rectangular, it is called a rectangular spring. Rectangular springs have been famous for their stable performance for many years. They are very suitable for occasions with high loads and very limited space. They are designed for use in holes or on shafts and meet the requirements of high-speed compression and overweight loads.

[0054] The clamping assembly 2 includes a clamping base 21, a top plate 22, two first clamping arms 23 and two second clamping arms 24. The clamping base 21 includes a rotating plate 211, a clamping frame 212 and a limiting member 213. The rotating plate 211 is rotatably connected to the support base 12. The clamping frame 212 is fixedly connected to the rotating plate 211. The limiting member 213 is mounted on the support base 12 and can be movably connected to the rotating plate 211 to switch between connection fixation and limit release. The limiting member 213 can be a indexing pin. A plurality of indexing holes are equidistantly arranged on the rotating plate 211. When the limiting member 213 is inserted into the indexing hole, the rotating plate 211 is connected and fixed to the support base 12. When the limit needs to be released, the limiting member 213 retracts from the indexing hole to release the limit between the rotating plate 211 and the support base 12. The top plate 22 is movably mounted in the clamping frame 212. The two first clamping arms 23 are both slidably mounted on the clamping frame 212 and are arranged opposite to the top plate 22 for clamping the column body 101 in a first direction. The first direction is perpendicular to the axis direction of the rotating shaft 13. The two second clamping arms 24 are both slidably mounted on the rotating plate 211 and are arranged opposite to each other for clamping the column body 101 in a second direction. The second direction is perpendicular to the first direction, that is, parallel to the axis direction of the rotating shaft 13.

[0055] The adjusting assembly 3 includes an adjusting plate 31 and two adjusting ejector rods 32. The adjusting plate 31 is fixed on the support frame 11. The adjusting ejector rods 32 are threadedly connected to the adjusting plate 31. The two adjusting ejector rods 32 respectively press against the top surfaces of the two supporting parts 141; one adjusting assembly 3 is configured for each support block 14.

[0056] For the pantograph mast tooling proposed in this embodiment, by releasing the fixation between the rotating plate 211 and the support seat 12 through the limiting member 213, the rotating plate 211 rotates relative to the support seat 12 to adjust the angle of the mounting plate 102 in the horizontal plane; by adjusting the distance from the end of the adjusting ejector rod 32 pressing against the supporting part 141 to the adjusting plate 31, the column body 101 rotates around the axis of the rotating shaft 13 to adjust the angle of the mounting plate 102 in the vertical plane, so as to align the mounting holes of the mounting position of the mounting plate 102 with the tunnel or the horizontal support frame 1, and then fasten them by bolt connection. This alignment method is simple and fast, and can greatly improve the assembly efficiency.

[0057] By the first support spring 15 being compressed between the support frame 11 and the bottom surface of the supporting part 141, the elastic force of the first support spring 15 supports the support frame 11, preventing workers from forgetting to tighten the four adjusting rods 32 after the pantograph mast installation is completed, which may cause the entire clamping assembly 2 to shake and collide during the movement, and improving the reliability and stability of the device; since the first support springs 15 are installed on both sides of the rotating shaft 13, the compression amount of the first support spring 15 on one side becomes larger and the elastic force becomes larger, while the compression amount of the first support spring 15 on the other side becomes smaller and the elastic force becomes smaller. The initial positions of the two first support springs 15 are compressed. To rotate in which direction, turn down the adjusting rod 32 on that side.

[0058] In some embodiments, two guiding grooves 2121 are symmetrically arranged on the clamping frame 212. The two guiding grooves 2121 are symmetrically arranged on both sides of the avoidance area. The middle of the clamping frame 212 is hollowed out. The guiding grooves 2121 penetrate the clamping frame 212 in the vertical direction, that is, the guiding grooves 2121 are provided on both the top surface and the bottom surface of the clamping frame 212. The guiding groove 2121 includes a straight section 21211 with a smooth transition and an inclined section 21212. The straight section 21211 is perpendicular to the rotating shaft 13. The two inclined sections 21212 extend in a direction away from each other starting from the straight section 21211. The inclined section 21212 is arranged at the opening end close to the avoidance area. Two sets of sliding columns 25 are provided on the first clamping arm 23. Two sliding columns 25 are connected to both the top surface and the bottom surface of the first clamping arm 23. The two sliding columns 25 on the top surface are slidably installed in the guiding groove 2121 on the top surface of the clamping frame 212 on the same side of the avoidance area, and the two sliding columns 25 on the bottom surface are slidably installed in the guiding groove 2121 on the top surface of the clamping frame 212 on the same side of the avoidance area; when both sets of sliding columns 25 are located in the straight section 21211, the two first clamping arms 23 and the top plate 22 form a clamping state; when one set of sliding columns 25 is located in the straight section 21211 and the other set of sliding columns 25 is located in the inclined section 21212, the two first clamping arms 23 are in an open state, which is convenient for guiding the column body 101 into the first clamping arm 23 or taking out the first clamping arm 23 from the column body 101. When one set of sliding columns 25 is located in the straight section 21211 and the other set of sliding columns 25 is located in the inclined section 21212, the two first clamping arms 23 are in an open state, which is convenient for guiding the column body 101 into the first clamping arm 23 or taking out the first clamping arm 23 from the column body 101; when both sets of sliding columns 25 are located in the straight section 21211, the two first clamping arms 23 and the top plate 22 form a clamping state to clamp the column body 101. This clamping method is convenient and fast, and has a good clamping effect, which can improve the assembly efficiency.

[0059] In some embodiments, the clamping assembly 2 further includes an intermediate block 26, two guide rods 27 and two first driving members 28; the intermediate block 26 is located on the side of the clamping frame 212 away from the opening, the guide rods 27 are slidably mounted on the clamping frame 212, and one end of each guide rod is hinged to the first clamping arm 23. A connecting shaft 251 is further provided on the first clamping arm 23. Two of the sliding columns 25 of a set of sliding columns 25 close to the intermediate block are respectively arranged at both ends of the connecting shaft 251. The connecting shaft 251 is hinged to the guide rod 27. The other ends of the two guide rods 27 are both connected to the intermediate block 26. The axis of the guide rod 27 and the axis of the straight section 21211 are in the same vertical plane; the first driving member 28 is a hydraulic cylinder. The first driving member 28 includes a first cylinder block 281 and a first telescopic rod 282. The first cylinder block 281 is connected to the clamping frame 212. One end of the first telescopic rod 282 is connected to the first cylinder block 281, and the other end is hinged to the intermediate block 26. When introducing the cylinder 101 into the first clamping arm 23 or removing the first clamping arm 23 from the cylinder 101, the first cylinder block 281 drives the first telescopic rod 282 to contract, so that the first clamping arm 23 moves towards the inclined section 21212. When a set of the sliding columns 25 is located on the straight section 21211 and the other set of the sliding columns 25 is located on the inclined section 21212, the two first clamping arms 23 move away from each other, thus being in an open state; when it is necessary to clamp the cylinder 101, the first cylinder block 281 drives the first telescopic rod 282 to extend, so that the first clamping arm 23 moves from the inclined section 21212 towards the straight section 21211. When both sets of the sliding columns 25 are located on the straight section 21211 and the first clamping arm 23 abuts against the cylinder 101, the two first clamping arms 23 and the top plate 22 form a clamping state. Through the transfer of the intermediate block 26, both the first driving member 28 and the guide rod 27 can be installed on the clamping frame 212. The first driving member 28 and the guide rod 27 are both located on the same side of the intermediate block 26, which can reduce the size of the device, make the structure more compact, occupy less volume, and facilitate the flexible layout of the device in a compact space.

[0060] In some embodiments, the clamping assembly 2 further includes a fixed seat 29 and a second driving member 230; the fixed seat 29 is fixedly installed on the rotating plate 211, and a first sliding groove 291 and a second sliding groove 292 are arranged on the fixed seat 29 along a second direction; the two second clamping arms 24 are respectively slidably installed in the first sliding groove 291 and the second sliding groove 292; one end of the second driving member 230 is connected to one of the second clamping arms 24, and the other end is connected to the other second clamping arm 24. The second driving member 230 can be a hydraulic cylinder. The second driving member 230 includes a second cylinder body 2301 and a second telescopic rod 2302. The second cylinder body 2301 is connected to one of the second clamping arms 24. One end of the second telescopic rod 2302 is connected to the second cylinder body 2301, and the other end is connected to the other second clamping arm 24. When it is necessary to clamp the cylinder 101, the second cylinder body 2301 drives the second telescopic rod 2302 to contract. After the second clamping arm 24 connected to the second telescopic rod acts first until it contacts the cylinder 101, the second clamping arm 24 connected to the second cylinder body 2301 acts until both second clamping arms 24 abut against the cylinder 101, and the clamping operation is completed.

[0061] In some embodiments, the outer wall of the rotating plate 211 is arc-shaped, and a rotating groove 2111 is arranged at the outer edge of the bottom surface of the rotating plate 211. The clamping seat 21 further includes a plurality of side guide wheels 214 and a plurality of bottom support members 215. The plurality of side guide wheels 214 are installed on the support seat 12. The plurality of side guide wheels 214 are evenly arranged along the circumferential direction of a circle with the center of the first rotating plate 211 as the center and a first diameter as the radius. The first diameter is equal to the sum of the diameter of the side guide wheel 214 and the outer wall diameter of the rotating plate 211, and is used to support and guide the peripheral wall of the rotating plate 211 and abut against the top surface of the rotating plate 211; the bottom support members 215 are installed on the support seat 12. The plurality of bottom support members 215 are evenly arranged along the circumferential direction of a circle with the center of the first rotating plate 211 as the center and a second diameter as the radius. The second diameter is equal to the outer wall diameter of the rotating plate 211 minus the width of the rotating groove 2111, and is used to support in the rotating groove 2111. The bottom support member 215 can be a ball column.

[0062] In some embodiments, the clamping assembly 2 further includes a second support spring 240 and a proximity switch 250. The second support spring 240 is compressed between the top plate 22 and the clamping seat 21, and the proximity switch 250 is installed at a position on the top surface of the clamping frame 212 close to the top plate 22. By the second support spring 240 being compressed between the top plate 22 and the clamping seat 21, in the initial state, the second support spring 240 pushes the top plate 22 outwards, making it away from the proximity switch 250 installed here. When the first clamping arm 23 clamps the suspension post 100, it will squeeze the top plate 22 in the direction away from the notch. At this time, the second support spring 240 is compressed, and the top plate 22 will lean against the limit post 260 beside the second support spring 240. The proximity switch 250 installed here will sense that the top plate 22 has reached the position, indicating that the suspension post 100 has been clamped, and the second clamping arm 24 below can start to clamp. The second support spring 240 can be a rectangular spring.

[0063] In some embodiments, the column body 101 is a cylinder 101, and an arc-shaped hole 221 is arranged in the middle of the top plate 22 in the vertical direction. The arc-shaped hole 221 is used to fit with the column body 101. When the column body 101 is a cylinder 101, through the arc-shaped hole 221 to fit with the column body 101, the contact area can be increased, the clamping effect can be improved, and the clamping can be made more stable and reliable.

[0064] In some embodiments, the railway catenary suspension post tooling further includes a chassis 4. The chassis 4 is used to connect with the robotic arm, and the support frame 1 is installed on the chassis 4. By connecting the support frame 1 and the robotic arm through the chassis 4, it can be used to move the suspension post 100 as a whole under the drive of the robotic arm, without manual handling, improving safety.

[0065] In some embodiments, a slide rail 41 parallel to the column body 101 is arranged on the chassis 4, and the support frame 1 is slidably installed on the slide rail 41; the railway catenary suspension post tooling further includes a third support spring 5. One end of the third support spring 5 is supported on the chassis 4, and the other end is supported below the support frame 1. Due to the support frame 1 and the suspension post 100 under the action of gravity, the third support spring 5 is compressed. When the mounting plate 102 is docked with the installation position of the tunnel or the horizontal support frame 1, the third support spring 5 can have a certain buffering effect on the mounting plate 102, avoiding damage to the tunnel or the horizontal support frame 1 caused by the impact of the mounting plate 102, and improving the reliability of installation. The third support spring 5 can be a rectangular spring.

[0066] In a further embodiment, a height measuring sensor may be provided to measure the distance to the installation position of the tunnel or the horizontal support frame 1, and then based on the distance from the clamping position of the column body 101 to the mounting plate 102, it is possible to avoid the mounting plate 102 hitting the tunnel or the horizontal support frame 1 during the movement process, thereby improving the reliability and stability of the assembly. The height measuring sensor may be installed on the fixed bracket 6 on the intermediate block 26. The height measuring sensor may be a laser ranging sensor or an ultrasonic sensor, etc. The working principle is as described in the prior art and will not be elaborated here.

[0067] Based on the same concept, an embodiment of the second aspect of the present invention provides an installation method for a railway catenary suspension post 100, using the railway catenary suspension post tooling as described in the embodiment of the first aspect, as Figure 14 shown, specifically including:

[0068] Step S1: Clamp the column body 101 in the first direction by the first clamping arm 23, and clamp the column body 101 in the second direction by the second clamping arm 24;

[0069] Step S2: Release the fixation of the rotating plate 211 and the support seat 12 by the limiting member 213, so that the rotating plate 211 rotates relative to the support seat 12, and adjust the angle of the mounting plate 102 in the horizontal plane;

[0070] Step S3: By adjusting the distance from the end of the adjusting jack rod 32 that presses against the supporting portion 141 to the adjusting plate 31, make the column body 101 rotate around the axis of the rotating shaft 13, and adjust the angle of the mounting plate 102 in the vertical plane to align the mounting hole positions of the mounting position of the mounting plate 102 with the tunnel or the horizontal support frame 1.

[0071] The installation method for the railway catenary suspension post 100 proposed in this embodiment releases the fixation of the rotating plate 211 and the support seat 12 by removing the limiting member 213, so that the rotating plate 211 rotates relative to the support seat 12, and adjusts the angle of the mounting plate 102 in the horizontal plane; adjusts the distance from the end of the adjusting jack rod 32 that presses against the supporting portion 141 to the adjusting plate 31, so that the column body 101 rotates around the axis of the rotating shaft 13, and adjusts the angle of the mounting plate 102 in the vertical plane to align the mounting hole positions of the mounting position of the mounting plate 102 with the tunnel or the horizontal support frame 1, and then fastens by bolt connection. This alignment method is simple and fast, and can greatly improve the assembly efficiency.

[0072] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
