[0002] The overhead contact system is the main structure of railway electrification engineering. It is a special type of power transmission line that runs along the railway line to supply power to electric locomotives. The overhead contact system consists of several parts: contact suspension, support devices, positioning devices, supports, and foundations. The cantilever arm is the support device for the overhead contact system, used to support the contact suspension and transfer its load to the supports or other structures. When the overhead contact system is installed in a location with a large span or in a tunnel, a suspension column is required. The suspension column is suspended from a horizontal support frame or installed on the tunnel ceiling, and then the cantilever arm is installed on the suspension column.

[0024] The railway catenary cantilever and suspension column installation equipment and method of this utility model have the following advantages over the prior art:

[0025] (1) The mounting frame is detachably connected to the cantilever arm fixture or the hanging column fixture. The robotic arm drives the cantilever arm fixture or the hanging column fixture to move. The moving mechanism drives the mounting frame to move relative to the connecting block along the X-axis, Y-axis and Z-axis to achieve the initial alignment of the installation position of the cantilever arm or the hanging column. The front wheel and the two rear wheels move on the railway, driving the movement of the entire device, which is convenient for long-distance transportation.

The movement is convenient and fast, which can improve the installation efficiency and avoid the possible injury to personnel caused by manual handling. The safety is high.

[0026] (2) The first screw is driven to rotate by the first driving component. Due to the restriction of the second guide rod, the connecting block can only move in a straight line along the second guide rod. The connecting block is installed on the robotic arm, so that the second guide rod and the two sliders slide together in the connecting block along the length direction of the second guide rod, realizing the X-axis movement of the mounting frame relative to the connecting block. The slider is driven to slide along the first guide rod by the second moving unit, realizing the Y-axis movement of the mounting frame relative to the connecting block. The third moving unit drives the mounting frame to move in a direction perpendicular to the plane where the bottom frame is located, realizing the Z-axis movement of the mounting frame relative to the connecting block. This allows for fine adjustment of the position of the hanging column fixture or the cantilever arm fixture, quickly adjusting the installation position of the hanging column or the cantilever arm, and improving installation efficiency.

[0027] (3) The positioning pin is installed on the mounting frame. The cantilever tool or the hanging column tool is provided with a positioning hole. The positioning pin is used to insert and cooperate with the positioning hole. After positioning, it is convenient to connect the connecting bolt and the connecting hole. It is more accurate and faster and can improve the assembly efficiency.

[0028] (4) The gyroscope is installed on the top surface of the mounting frame to measure the tilt angle of the mounting frame. Combined with the pre-measured angle of the mounting surface, the cantilever arm fixture or the hanging column fixture can be adjusted to the required angle by the robotic arm in a relatively convenient and quick manner, thereby improving the installation efficiency.

[0050] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0051] Reference Figure 1-11 As shown in the embodiment of this utility model, a railway catenary cantilever and suspension column installation device is proposed, including a car body 1, a robotic arm 2, and a connecting assembly 3, wherein:

[0052] The car body 1 includes a frame 11, two front wheels 12 and two rear wheels 13, with the two front wheels 12 and the two rear wheels 13 located below the frame 11 for moving on the railway.

[0053] The robotic arm 2 is mounted on the vehicle frame 11, and the robotic arm 2 has multiple degrees of freedom;

[0054] The connecting assembly 3 includes a connecting block 31, a mounting frame 32, and a moving mechanism 33. The connecting block 31 is mounted on the end of the robotic arm 2. The mounting frame 32 is detachably connected to the cantilever arm fixture 100 or the hanging column fixture 200. The moving mechanism 33 is connected to both the connecting block 31 and the mounting frame 32, and is used to drive the mounting frame 32 to move relative to the connecting block 31 along the X-axis, Y-axis, and Z-axis. This device can simultaneously connect the cantilever arm fixture 100 and the hanging column fixture 200, completing the installation of the cantilever arm and the hanging column. It has good compatibility and a wide range of applications.

[0055] The railway catenary cantilever and suspension column installation equipment proposed in this embodiment is detachably connected to the cantilever tool 100 or suspension column tool 200 through the installation frame 32. The robotic arm 2 drives the cantilever tool 100 or suspension column tool 200 to move and achieve preliminary alignment of the installation position of the cantilever or suspension column. The front wheel 12 and the two rear wheels 13 move on the railway, driving the movement of the entire device, which is convenient for long-distance transportation. The movement and preliminary alignment do not require manual operation, making the movement convenient and quick, improving installation efficiency, and avoiding the possible injury to personnel caused by manual handling, thus ensuring high safety.

[0056] In some embodiments, the moving mechanism 33 includes a base frame 331, a first moving unit 332, a second moving unit 333, and a third moving unit 334, wherein:

[0057] The bottom frame 331 includes a first crossbeam 3311, a second crossbeam 3312, and two first guide rods 3313. The first crossbeam 3311 and the second crossbeam 3312 are arranged parallel to each other in the horizontal direction and are both connected to the mounting frame 32. The two ends of the first guide rods 3313 are respectively connected to the first crossbeam 3311 and the second crossbeam 3312 to form a frame structure.

[0058] The first moving unit 332 includes two second guide rods 3321, two sliders 3322, a first lead screw 3323, and a first driving member 3324. The two ends of the second guide rods 3321 are fixedly connected to the two sliders 3322 respectively. The connecting block 31 is slidably mounted on the second guide rods 3321. The two second guide rods 3321 are parallel to the first lead screw 3323 and perpendicular to the first guide rods 3313. The two sliders 3322 are slidably mounted on the two first guide rods 3313 respectively. The first lead screw 3323 is threadedly connected to the connecting block 31. The first driving member 3324 is mounted on one of the sliders 3322 and is driven by the first lead screw 3323. The first driving member 3324 can be a motor.

[0059] The second moving unit 333 is connected to the slider 3322 and is used to drive the slider 3322 to slide along the first guide rod 3313;

[0060] The third moving unit 334 is connected to the bottom frame 331 and the mounting frame 32 respectively, and is used to drive the mounting frame 32 to move in a direction perpendicular to the plane where the bottom frame 331 is located.

[0061] In this embodiment, the moving mechanism 33 drives the first lead screw 3323 to rotate via the first driving member 3324. Due to the restriction of the second guide rod 3321, the connecting block 31 can only move linearly along the second guide rod 3321. The connecting block 31 is mounted on the robotic arm 2, allowing the second guide rod 3321 and the two sliders 3322 to slide together within the connecting block 31 along the length of the second guide rod 3321, thus achieving X-axis movement of the mounting frame 32 relative to the connecting block 31. The second moving unit 333 drives the sliders 3322 to slide along the first guide rod 3313, thus achieving Y-axis movement of the mounting frame 32 relative to the connecting block 31. The third moving unit 334 drives the mounting frame 32 to move in a direction perpendicular to the plane of the bottom frame 331, thus achieving Z-axis movement of the mounting frame 32 relative to the connecting block 31. This allows for fine-tuning of the position of the hanging column fixture or the cantilever arm fixture, enabling faster adjustment of the mounting position of the hanging column or the cantilever arm and improving installation efficiency.

[0062] In some embodiments, the second moving unit 333 includes a second lead screw 3331, a mounting plate 3332, a driving block 3333, and a second driving member 3334. The second lead screw 3331 is arranged parallel to the first guide rod 3313. The two ends of the mounting plate 3332 are respectively fixedly connected to the two sliders 3322. The driving block 3333 is mounted on the mounting plate 3332 and threadedly connected to the second lead screw 3331. The second driving member 3334 is mounted on the first crossbeam 3311 and drivenly connected to the second lead screw 3331. The second drive element 3334 drives the second lead screw 3331 to rotate. The second lead screw 3331 drives the drive block 3333. Due to the restriction of the mounting plate 3332 and the two sliders 3322, the drive block 3333 can only move linearly along the length direction of the second lead screw 3331, causing the two sliders 3322 to slide along the first guide rod 3313. This realizes the Y-axis movement of the mounting frame 32 relative to the connecting block 31, thereby allowing for fine adjustment of the position of the hanging column fixture or the cantilever fixture, quickly adjusting the installation position of the hanging column or cantilever, and improving installation efficiency. The second drive element 3334 can be a motor.

[0063] In some embodiments, the third moving unit 334 includes two third guide rods 3341, two fourth guide rods 3342, two screw jacks 3343, a coupling 3344, and a third driving member 3345; the third guide rods 3341 and the fourth guide rods 3342 are both perpendicular to the plane of the mounting frame 32; one end of each of the two third guide rods 3341 is slidably mounted parallel to the first crossbeam 3311, and the other end is fixedly connected to the mounting frame 32; one end of each of the two fourth guide rods 3342 is slidably mounted parallel to the second crossbeam 3312, and the other end is fixedly connected to the mounting frame 32; the two screw jacks 3343 are respectively mounted on the first crossbeam 3311 and the second crossbeam 3312; the third driving member 3345 is connected to one of the screw jacks 3343. Through the action of coupling 3344, the third drive component 3345 simultaneously drives two screw jacks 3343. The two screw jacks 3343 drive the third guide rod 3341 to slide in the first crossbeam 3311 and the fourth guide rod 3342 to slide in the second crossbeam 3312. This causes the mounting frame 32 to move along the length direction of the third guide rod 3341, thereby realizing the Z-axis movement of the mounting frame 32 relative to the connecting block 31. This allows for fine-tuning of the position of the hanging column fixture or cantilever fixture, enabling faster adjustment of the installation position of the hanging column or cantilever, and improving installation efficiency. The third drive component 3345 can be a motor.

[0064] In some embodiments, the connecting assembly 3 further includes a connecting bolt. The mounting frame 32 has a mounting hole 321, and the cantilever arm fixture 100 or the hanging column fixture 200 has a connecting hole 300. The connecting bolt passes through the connecting hole 300 and connects to the mounting hole 321. After aligning the connecting hole 300 and the mounting hole 321, the connecting bolt passes through the connecting hole 300 and connects to the mounting hole 321, thus achieving a detachable connection between the mounting frame 32 and the cantilever arm fixture 100 or the hanging column fixture 200.

[0065] In some other embodiments, other detachable connection methods such as plug-in or snap-fit ​​connections can be used, as long as the mounting frame 32 can be detachably connected to the cantilever tool 100 or the hanging column tool 200.

[0066] In some embodiments, the connecting assembly 3 further includes a positioning pin 34, which is mounted on the mounting frame 32. The cantilever arm fixture 100 or the hanging column fixture 200 has a positioning hole 400, and the positioning pin 34 is used to engage with the positioning hole 400. By mounting the positioning pin 34 on the mounting frame 32, and by engaging the positioning pin 34 with the positioning hole 400, the relative position of the fixture remains unchanged after each fixture change. After positioning, this facilitates the connection of the connecting bolts with the connecting hole 300, making the connection more accurate and faster, and improving assembly efficiency.

[0067] In some embodiments, the railway catenary cantilever and suspension column installation equipment further includes a gyroscope 4, which is mounted on the top surface of the installation frame 32 and used to measure the tilt angle of the installation frame 32. By measuring the tilt angle of the installation frame 32 using the gyroscope 4, the cantilever fixture 100 or suspension column fixture 200 can be adjusted to a horizontal state more conveniently and quickly, thereby improving installation efficiency.

[0068] In some embodiments, the vehicle body 1 further includes a fourth drive component 14, a front axle 15, a rear axle 16, and two transport chassis 17. The fourth drive component 14 is mounted on the frame 11 and is drivenly connected to the rear axle 16. The two front wheels 12 are mounted at both ends of the front axle 15; the two rear wheels 13 are mounted at both ends of the rear axle 16. The two transport chassis 17 are detachably connected to the front axle 15 and the rear axle 16, respectively, to support the frame 11. The detachable connection of the two transport chassis 17 to the front axle 15 and the rear axle 16 allows the vehicle body 1 to be disassembled, facilitating modularization of the device and disassembly for transport when not in use, thus improving the device's applicability. The transport chassis 17 here can be snapped into the front axle 15 or the rear axle 16 to achieve a detachable connection. The fourth drive component 14 can be a diesel engine.

[0069] In some embodiments, the robotic arm 2 includes a base 21 and an arm body 22. The base 21 is detachably connected to the frame 11, and the arm body 22 is fixed to the base 21. The top surface of the frame 11 is provided with a first clamping piece 111, and the bottom surface of the base 21 is provided with a second clamping piece 211. The first clamping piece 111 and the second clamping piece 211 are connected by fastening bolts 5 to achieve a detachable connection between the base 21 and the frame 11. The arm body 22 has multiple degrees of freedom, such as rotation, X-axis movement, Y-axis movement, and Z-axis movement.

[0070] In some embodiments, the robotic arm 2 further includes four support legs 23, which are vertically mounted on the base 21 and form a rectangle. When the support legs 23 are lowered to rest on the ground, they support and secure the entire device, preventing the vehicle body 1 from moving during robotic arm 2 operation and improving the reliability and stability of the device.

[0071] In some embodiments, the vehicle body 1 further includes two steering wheels 18, which are respectively mounted on the front and rear ends of the frame 11 and are both connected to the front wheels 12 via a drive mechanism. Since both steering wheels 18 are connected to the front wheels 12 via a drive mechanism, both steering wheels 18 can control the steering of the front wheels 12, making operation more convenient and eliminating the need for U-turns, thus improving the reliability of the device.

[0072] In some embodiments, the railway catenary cantilever and suspension column installation equipment also includes a vision recognition camera mounted on the installation frame 32. The vision recognition camera identifies the position of the installation location of the suspension column or cantilever, enabling coarse motion adjustment of the robotic arm and improving assembly efficiency.

[0073] The working principle of the railway catenary cantilever and suspension column installation equipment proposed in this embodiment is as follows: the mechanical arm 2 drives the installation frame 32 to move, so that the positioning pin 34 is inserted into the positioning hole 400, and the connecting bolt passes through the connecting hole 300 to connect with the installation frame 32, thereby realizing the connection between the installation frame 32 and the cantilever tool 100 or the suspension column tool 200; the mechanical arm 2 drives the cantilever tool 100 or the suspension column tool 200 to move, and realizes the preliminary alignment of the installation position of the cantilever or suspension column; the front wheel 12 and the two rear wheels 13 move on the railway, driving the movement of the entire device, which is convenient for long-distance transportation. The movement and preliminary alignment do not require manual operation, and the movement is convenient and quick, which can improve the installation efficiency and avoid the possible injury to personnel caused by manual handling, thus ensuring high safety.
