[0033] like Figure 1 , 2 The illustrated device is a column installation apparatus used to install cylindrical contact wire columns 60 onto a foundation for the contact wire column 60. The apparatus includes a traveling mechanism, a lifting mechanism, a positioning and adjustment mechanism 3, a power system, and a control system 5. The following provides a detailed description of each mechanism and system:

[0034] The walking mechanism adopts a track locomotive 1 that can walk on the track. The track locomotive 1 is configured with a bogie, a traction hook, a braking system, etc. The traction hook mounted on the track locomotive 1 can be pulled by other track trolleys to walk; the braking system on the track locomotive 1 can not only meet the braking during driving, but also meet the parking braking when installing the catenary column 60, especially the braking force when installing the catenary column 60 on the slope. The lifting mechanism, the positioning adjustment mechanism 3, the power system, and the control system are all arranged on the track locomotive 1, and during construction, they are pulled by the traction trolley to the vicinity of the catenary column foundation 61 for installation operation.

[0035] The lifting mechanism is arranged on the walking mechanism, i.e. on the track locomotive 1. The lifting mechanism includes a lifting arm 2, which can lift and transport the catenary column 60 to the track locomotive 1 through rotation, pitching, telescoping, etc., or lift and transport the catenary column 60 from the track locomotive 1 to the vicinity of the catenary column foundation 61. It can be controlled independently for lifting and transporting the catenary column 60 or other goods, or it can be adjusted simultaneously with the positioning adjustment mechanism 3 to adjust the position and posture of the catenary column 60. After the lifting arm 2 is retracted, it fully meets the track limit requirements, and after the lifting arm 2 is extended, it meets the extension length and bearing capacity for lifting and transporting the catenary column 60 from the track locomotive 1 to the vicinity of the catenary column foundation 61.

[0036] The adjustment of the position and posture of the catenary column 60 is mainly performed by the positioning adjustment mechanism 3, which finally realizes that the installation base of the catenary column 60 is in complete parallel contact with the catenary column foundation 61, and the installation worker only needs to tighten the anchor bolt to complete the installation of the catenary column 60.

[0037] In the present embodiment, as shown in Figure 3 The positioning adjustment mechanism 3 is arranged at one end of the track locomotive 1 and mainly includes a base, a first support 31, a second support 32, and a pair of arms 33. The positioning adjustment mechanism 3 not only can hold the catenary column 60, but also can realize the movement, rotation, pitching, and rotation of the catenary column 60 in two directions, i.e. adjustment of five degrees of freedom. Specifically,

[0038] The base includes a first base 300 and a second base 301, and the first base 300 and the second base 301 are distributed left and right. As shown in the figure, the first base 300 and the second base 301 are both provided with two, and the two first bases 300 and second bases 301 are distributed front and back.

[0039] The first support 31 is rotatably connected to the base. Specifically, the first support 31 is rotatably connected to the first base 300 through a swing rotary joint, and the rotation center line of the first support 31, i.e., the rotation shaft of the swing rotary joint, extends in the horizontal direction. A swing oil cylinder 34 is connected between the first support 31 and the second base 301, the cylinder barrel seat of the swing oil cylinder 34 is fixed to the second base 301, and the piston rod end of the swing oil cylinder 34 is connected to the upper first support 31 using a spherical seat, forming a swing rotary joint as a rotary pair. The extension and contraction of the swing oil cylinder 34 can drive the first support 31, the upper part and the catenary post 60 to swing in the horizontal direction, so that the catenary post 60 is parallel to the catenary post foundation 61 in the horizontal direction.

[0040] The second support 32 is movable relative to the first support 31 in a first direction and rotatable relative to the first support 31. The first direction is consistent with the extension direction of the rotation center line of the first support 31, and the extension direction of the rotation center line of the second support 32 is also a horizontal direction and perpendicular to the first direction.

[0041] In the embodiment, the movement of the second support 32 relative to the first support 31 is specifically realized through a frame 35 and a first moving assembly. The first moving assembly includes a first sliding rail 360, a first sliding block 361 slidably arranged on the first sliding rail 360, and a moving oil cylinder 362 driving the first sliding block 361 to slide. The first sliding rail 360 is arranged in parallel in two pieces and is installed on the upper plane of the first support 31 and extends in the first direction. Four first sliding blocks 361 are connected below the frame 35, and two first sliding blocks 361 are matched on one first sliding rail 36. The cylinder barrel seat of the moving oil cylinder 362 is installed on the end face of the first support 31, and the piston rod seat of the moving oil cylinder 362 is installed on the frame 35. The extension and contraction of the moving oil cylinder 362 drives the frame 35, the upper part and the catenary post 60 to move along the first sliding rail 360 to the target position where the catenary post 60 is installed, realizing the movement and alignment compensation in the first direction.

[0042] The second support 32 is rotatably connected to the frame 35 and is rotatable relative to the frame 35 and the first support 31 through a pitching oil cylinder 37. The pitching oil cylinder 37 is arranged in two pieces, the cylinder barrel seats of the two pitching oil cylinders 37 are hinged to the frame 35, the piston rods of the two pitching oil cylinders 37 are hinged to the second support 32, the second support 32 is hinged to the frame 35 through a swing rotary joint, forming a pitching rotary pair, the two pitching oil cylinders 37 are synchronously controlled by using an electric proportional control valve to control the speed and amplitude of the extension and contraction, realizing the pitching of the frame 35, the upper part and the catenary post 60 around the second direction, so that the catenary post 60 is perpendicular to the catenary post foundation 61 in the vertical direction.

[0043] A pair of arms 33 are connected to the second support 32 and can be relatively close or far apart. In this embodiment: the close or far apart of the pair of arms 33 is specifically realized by the second moving assembly. The second moving assembly includes a second sliding rail 380, a second sliding block 381 slidably disposed on the second sliding rail 380, and a clamping oil cylinder 382 driving the pair of arms 33 to be relatively close or far apart, the second sliding rail 380 is parallel to two, mounted on the second support 32 and extends along the second direction, the second direction is consistent with the extension direction of the center line of the second support 32 rotation, each arm 33 is connected with two second sliding blocks 381 respectively, one second sliding rail 380 is matched with the second sliding block 381 of one arm 33. The cylinder barrel seat of the clamping oil cylinder 382 is installed on the hinged support at both ends of the second support 32, and the piston rod seat of the clamping oil cylinder 382 is installed on the hinged support of the two arms 33. The extension of each clamping oil cylinder 382 controls the close or far apart of the arm 33, realizes the clamping or disengaging of the arm 33 from the contact net column 60, and the two clamping oil cylinders 382 act simultaneously, when one of the clamping oil cylinders 382 continues to extend while the arm 33 clamps the contact net column 60, the contact net column 60 can be moved to the target position of the contact net column 60 installation along the direction of the second sliding rail 380, realizing the movement and alignment compensation of the second direction; the two clamping oil cylinders 382 are retracted, and the pair of arms 33 are far apart, so that the arm 33 can be disengaged from the contact net column 60.

[0044] In addition, in this embodiment, a pressure sensor is arranged in the hydraulic system of the clamping oil cylinder 382 for controlling the clamping force of the pair of arms 33.

[0045] As shown in Figure 4 : The inner side of the pair of arms 33 is provided with a plurality of driving rotary rollers 390, driven rotary rollers 391, and rotary driving members driving the driving rotary rollers 390 to rotate, and the rotation center lines of the driving rotary rollers 390 and the driven rotary rollers 391 extend in the vertical direction. It is shown that 2 driving rotary rollers 390 and 5 driven rotary rollers 391 are arranged on one arm 33 and distributed in a shape consistent with the outer periphery of the column, such as circumferential distribution, to realize the purpose of circumferential clamping of the contact net column 60. The driving rotary roller 390 and the driven rotary roller 391 have a main body part located in the middle and an end part located at both ends, the main body part is cylindrical, and the end part is drum-shaped, which leaves an adjustment gap for swing and pitch, and is also beneficial to the sliding when the contact net column 60 is lowered.

[0046] The rotating drive member adopts a rotary motor 393 and a speed reducer 394. The rotary motor 393 is selected to be a low-speed large-torque motor. The speed reducer 392 has a speed reduction ratio of 100, which increases the output torque and improves the adjustment accuracy. Each rotary motor 393 is connected with a corresponding speed reducer 394 and is installed in the driving rotary roller 390, so as to output the rotary torque of the rotary motor 393 to the driving rotary roller 390. The driving rotary roller 390 rotates under the clamping force of the clamping cylinder 382 and generates a friction force with the catenary post 60, so as to drive the catenary post 60 to rotate and realize the concentric positioning of each fixed flange hole of the catenary post 60 and the foundation bolt of the catenary post foundation 61.

[0047] In addition, an accumulator is arranged in the hydraulic assembly of the two clamping cylinders 382. When the catenary post 60 is clamped, the accumulator is closed, the clamping cylinder 382 provides sufficient clamping force, and the catenary post 60 can rotate. When the catenary post 60 needs to be lowered for butt joint after being positioned, the accumulator is opened, the friction force is removed, and the catenary post 60 is lowered to the catenary post foundation 61 by the boom 2.

[0048] For the cylindrical catenary post 60, the boom 33 adopts a semicircular structure, and a reinforcing rib plate 392 is arranged between each rotary roller, so as to increase the strength of the overall structure.

[0049] A visual sensor 395 is arranged below each boom 33. The visual sensor 395 is connected with the control system of the hoisting mechanism. One is used to sense the position of the catenary post foundation 61, send a position instruction to the boom 2, and hoist the catenary post to a specified position. The other is used to sense the relative position of the fixed flange hole and the foundation bolt of the catenary post foundation 61 after the catenary post 60 is clamped by the positioning adjustment mechanism 3. The position and posture of accurate positioning are output through the optimization algorithm of the industrial computer, so as to control the accurate movement of the boom 2 and the positioning adjustment mechanism 3.

[0050] The power system includes a power source and a hydraulic assembly 40. In the embodiment, the power source is a small generator set 41 arranged on the track locomotive 1, which provides power for the boom 2, the hydraulic assembly 40 and the like.

[0051] The hydraulic assembly 40 is composed of a hydraulic pump, various direction, flow and pressure control valves, a motor and some hydraulic auxiliary components. The hydraulic pump provides hydraulic power for each cylinder. The direction and flow control valves adopt proportional valves, which control the moving or rotating amplitude and speed of each cylinder and motor, can realize fine adjustment in each movement direction, facilitate accurate positioning, have high control accuracy and strong controllability. In addition to the clamping cylinder 382, other cylinders can also be provided with an accumulator filled with a certain pressure. When elastic adjustment is needed, the pre-charge pressure of the accumulator is matched to adapt to the elastic variation.

[0052] The control system 5 adopts CAN bus communication, each execution element is configured with a driver, and various signals such as the position, posture, system pressure and the like of each execution mechanism are fed back in real time, and then input into the main control box through a multi-core cable, and then processed by the central computer of the main control box, and then directly sent to each terminal control, regulation and execution mechanism through digital-to-analog conversion or digital switching value, so as to form a closed loop control, and achieve synchronous control or independent control of the boom 2 and the positioning adjustment mechanism 3 according to needs.

[0053] When installing: the overhead line post 60 is lifted from the track locomotive 1 by the boom 2 to the overhead line post foundation 61, and through the positioning adjustment mechanism 3, the overhead line post 60 is held to move, turn, hold tightly, rotate the post and the like, the position and posture of the overhead line post are adjusted, the accurate centering and positioning of the installation flange hole of the overhead line post 60 and the foundation bolt of the overhead line post foundation 61 are realized, the centering and positioning process is automatically controlled by the visual sensor 395, and finally the installation base of the overhead line post 60 is completely in parallel contact with the overhead line post foundation 61, and the installation worker only needs to tighten the foundation bolt to complete the installation of the overhead line post 60, as shown in Figure 5 .

[0054] The embodiment realizes the accurate positioning of the installation flange bolt hole of the cylindrical overhead line post and the foundation bolt of the overhead line post foundation by the mechanized and intelligent equipment, and the installation worker only needs to tighten the foundation bolt to complete the installation of the overhead line post. The use of the equipment changes the traditional installation process that the cylindrical overhead line post is completely lifted, centered and installed by manpower, greatly reduces the labor intensity of workers, improves the operation efficiency and construction process quality, has high mechanization and intelligent integration, is convenient to use, and has good application prospect.

[0055] The above embodiments are only for illustrating the technical concept and characteristics of the present application, the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application.
