Description

Technical Field

[0001] The present invention relates to the technical field of overhead power transmission lines, and in particular to an intelligent protection platform for railway crossing construction in a track-occupying power transmission project. Background Art

[0002] In the process of power transmission line construction, it is inevitable to cross the high-voltage or ultra-high-voltage transmission lines, railways, and highways that have been put into operation for line construction; in addition, with the rapid expansion of my country's high-speed railway network, there are more and more cases of line construction crossing high-speed railways and other electrified railways during the operation and maintenance of new transmission lines and existing lines. If effective safety measures are not taken, it will endanger the safety of railway power supply and cause serious social impact. The method commonly used in the industry is to set up a crossing frame and a safety net, that is, to set up a safety net of a certain width at a safe distance above the crossed lines and facilities. Even if extreme situations occur during the construction process, in the event of an accident where the wire accidentally falls, the safety net can reliably support it, thereby effectively protecting the crossed objects.

[0003] A crossing frame for crossing high-speed railway or highway construction disclosed in Chinese patent CN118554333A includes a frame assembly, a sealing net traction device, main load-bearing cables and a sealing net; two frame assemblies are arranged and are respectively placed on the left and right sides of the object to be crossed; the frame assembly includes a crossbeam, a main column, an assembled base and an assembled ground anchor; two main load-bearing cables are provided and are respectively connected to the crossbeams of the left and right side frame assemblies, and the sealing net is hung between the two main load-bearing cables; two sealing net traction devices are provided and are respectively installed on the crossbeams of the left and right side frame assemblies, and the two sealing net traction devices are connected to the sealing net traction.

[0004] However, the railway crossing protection equipment still has the following problems in actual use: Due to the high density of trains and high speed of the railway network during the day, when carrying out the construction of crossing the railway, the work can only be carried out during the night window period, and the operation time is short. If the existing protective device cannot be erected in one window period, the construction must be stopped and it is necessary to wait for the next window period to continue the construction so that the railway can be opened to traffic, otherwise the railway will be suspended. When crossing construction is carried out in different areas on the same railway line, it is necessary to repeat the construction, and the construction process also requires the occupation of field farmland, which will be affected by the terrain of the erection. When the terrain is more complex, it will affect the stability and safety of the erection. At the same time, the different ropes that make up the protective net are rigidly connected. When the wires, steel strands or other long strips in the direction of the crossing are dropped from above, the rebound force generated by the tension of the ropes will cause the protective net to shake or vibrate. During the shaking or vibrating process of the protective net, the wires, steel strands or other long strips in the direction of the crossing may fall from the protective net, which poses certain safety hazards.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The embodiment of the intelligent protection platform for railway crossing construction of track-occupied power transmission engineering of the present invention is as follows: Figure 1 , Figure 2 and Figure 5 As shown, it includes a vehicle body 1, a side box plate 2 is arranged on the vehicle body 1, a moving mechanism 3 is arranged on the vehicle body 1 and the side box plate 2, a working chassis 4 is arranged at the output end of the moving mechanism 3, and a lifting support mechanism is arranged on the working chassis 4. In this embodiment, the lifting support mechanism includes a support column 5 and a first hydraulic cylinder 6. The top of the working chassis 4 is hinged with a support column 5, the number of the support columns 5 is two, a first hydraulic cylinder 6 is arranged between the support column 5 and the working chassis 4, a connecting mechanism 7 is hinged at one end of the support column 5 away from the working chassis 4, a connecting mechanism 7 is arranged on the lifting support mechanism, and a working platform 8 is arranged on the connecting mechanism 7. A parallelogram structure is formed between the two support columns 5, the working chassis 4 and the connecting mechanism 7 to ensure that the connecting mechanism 7 is always in a horizontal state during the lifting process, thereby ensuring that the working platform 8 is in a horizontal state. Protective nets 9 are arranged on both sides of the working platform 8, and hydraulic support legs 10 are arranged on the side box plates 2. When the vehicle body 1 reaches the working position, after it stops and is locked, it can be flipped on one side or both sides according to the needs of the site. The side box plates 2 are unfolded and the hydraulic support legs 10 are started to rest against the ground on both sides of the track to form a stable support. After the support is stable, the mobile mechanism 3 can realize the overall translation of the working chassis 4 and its top equipment, which is used to avoid the position of the overhead railway contact network line to ensure that subsequent operations will not interfere with the contact network line. The mobile mechanism 3 cooperates with the side box plates 2 and the hydraulic support legs 10 to achieve unilateral translation or bilateral translation. Because the contact network needs to be avoided, the translation operation of the mobile mechanism 3 and the lifting operation of the lifting support mechanism are interlocked. Only when the lifting support mechanism is fully retracted can the mobile mechanism 3 be moved to ensure stability during movement. The mobile mechanism 3 includes a translation track, a translation wheel set, a locking structure, a cable drag chain, a translation drive device, etc. It should be noted that the interlocking relationship between the translation operation of the mobile mechanism 3 and the lifting operation of the lifting support mechanism is a prior art or can be implemented using a prior art. The structure and working principle of the mobile mechanism 3 are also prior art or can be implemented using a prior art.

[0022] This application also includes a safety detection system and an operation control system. The safety detection system has the functions of monitoring the operating status of the equipment, realizing equipment safety detection, feedback of the specific position of the equipment, checking the interlocking of different equipment, determining whether the safety device is effective, emergency handling, data feedback, fault diagnosis, etc., which is the key to realizing the safe and reliable operation of the crossing device. The safety detection system includes various switch components, limit position detection components, emergency stop safety components, speed detection components, position detection components, video monitoring systems, brakes, safety latches and positioning device detection, safety warning devices, etc. The operation control system controls the normal operation of the entire equipment system. The operation control system consists of equipment operation control, operation display, sound and light alarm and other parts. It uses industrial control equipment and industrial networks to control mechanical equipment to realize the operation, display, detection, fault judgment and other functions of the system. The two consoles of the operating system are backed up by each other, and the control system can be powered on or off, parameters can be set, and operation can be performed at any console. After the target working condition is set, one-key operation is automatically in place. The forward and reverse speed control can also be manually operated. The control system consists of a main PLC, a field PLC, a frequency converter, a sensor, cables and wires, etc. The monitoring, parameter setting and network interface functions are realized through the touch screen, and the on-site PLC realizes the control and signal acquisition functions. It should be noted that the safety detection system and the operation control system are both existing technologies or can be realized by using existing technologies.

A second slide groove 925 is provided on the connecting frame 923, and the number of the second slide grooves 925 is two. The spacing between the two second slide grooves 925 close to one end of the connecting shaft 921 is greater than the spacing between the two second slide grooves 925 away from one end of the connecting shaft 921. A slider 926 is slidably connected in the second slide groove 925, and a second elastic member 927 is provided between the slider 926 and the connecting frame 923. A friction wheel 928 is provided on one side of the slider 926. A hook 929 is rotatably connected to the side of the connecting frame 923 away from the second connecting rope 92, and the hook 929 is connected to the connecting ring 911.

[0029] The working process is as follows: S1. When the railway contact network is inspected and maintained, after reaching the working position and the car body 1 is stopped and locked, the side box plate 2 can be flipped on one side or both sides to unfold according to the needs of the site, and the hydraulic support legs 10 are started to rest on the ground on both sides of the track to form a stable support; S2. After the support is stable, the moving mechanism 3 can realize the overall translation of the working chassis 4 and its top equipment to adjust the position of the top equipment of the working chassis 4, and then start the first hydraulic cylinder 6, the support column 5 drives the workbench 8 to rise through the connecting mechanism 7, start the first driving member 703, the first driving member 703 drives the second gear 705 to rotate through the first gear 704, and the second gear 705 drives the workbench 8 to rotate through the second connecting platform 702 to adjust the angle of the workbench 8; S3, start the second driving member 85, the second driving member 85 drives the third gear 86 to rotate, because the rack 706 is fixedly connected to the second connecting platform 702 and the third gear 86 and the rack 706 are meshed with each other, when the third gear 86 rotates, it will drive the workbench 8 to move on the second connecting platform 702, and adjust the position of the workbench 8, so that the staff on the workbench 8 can inspect and maintain the railway contact network; S4. When performing the crossing construction, the moving mechanism 3 can realize the overall translation of the working chassis 4 and its top equipment to avoid the position of the overhead railway contact network line, ensuring that the subsequent operations will not interfere with the contact network line, and then start the first hydraulic cylinder 6, and the support column 5 drives the workbench 8 to rise through the connecting mechanism 7, so that the horizontal height of the workbench 8 is higher than the horizontal height of the railway contact network; S5, then start the second hydraulic cylinder 84, the second hydraulic cylinder 84 drives the deployment arm 82 to rotate and deploy, start the third driving member 822, the third driving member 822 drives the screw 823 to rotate, the screw 823 drives the crossbeam 83 and the winding roller 912 to move along the first slide groove 821 on the deployment arm 82 through the connecting seat 824, and drives the protection net 9 to deploy, so as to realize the safety protection when the transmission line crosses the railway track; S6. During the construction of the transmission line crossing, when a conductor, steel strand or other long strip component in the direction of the crossing falls on the protective net 9, at the moment when the conductor, steel strand or other long strip component in the direction of the crossing falls on the protective net, the force on the second connecting rope 92 suddenly increases, and the second connecting rope 92 pulls the connecting shaft 921 to slide in the connecting frame 923, and the first elastic member 924 contracts to buffer the second connecting rope 92; S7, when the second connecting rope 92 is pulled, the friction wheel 928 rotates due to the friction between the second connecting rope 92 and the second connecting rope 92, so that the slider 926 slides in the second slide groove 925, and the second elastic member 927 stretches; S8. Since there are two second slide grooves 925, and the spacing between the two second slide grooves 925 close to one end of the connecting shaft 921 is greater than the spacing between the two second slide grooves 925 away from one end of the connecting shaft 921, as the slider 926 slides in the second slide groove 925, the friction wheel 928 will squeeze the second connecting rope 92, increasing the friction between the friction wheel 928 and the second connecting rope 92, so that the second connecting rope 92 moves slowly on the connecting frame 923, and the second connecting rope 92 is slowly tightened at the moment of being stressed, reducing the rebound force generated by the second connecting rope 92 being suddenly tightened by the force, thereby reducing the shaking or jittering of the protective net 9, and preventing the protective net 9 from causing the wires, steel strands or other long strip components in the spanning direction that fall on it to fall from the protective net 9 during the shaking or jittering process, thereby improving safety.
