Description

Technical Field

[0001] This utility model relates to the field of rail transit signaling and control technology, specifically an intelligent loop forming device for railway signaling engineering. Background Technology

[0002] Intelligent loop forming devices in railway signaling engineering are intelligent devices used in railway signaling control systems (especially track circuits or cable networks). They are mainly used to realize automatic signal connection, loop configuration or fault diagnosis to improve system reliability and maintenance efficiency.

[0003] In the entire railway signal control system equipment, the pantograph is a key component for electric locomotives or EMUs to obtain electrical energy from the overhead contact line. It is used to obtain electrical energy from the overhead contact line to supply power to the train traction, auxiliary systems and signal equipment. It can maintain stable current collection under high-speed operation conditions, while adapting to the geometric changes of the overhead contact line (such as height, gradient, vibration, etc.) to ensure the safety of train power supply and operating efficiency.

[0004] Therefore, based on the above retrieval and combined with existing information, the carbon strip at the head of the pantograph is responsible for direct contact with the overhead contact line cable and conducting current. However, in cold environments, ice and snow easily condense on the surface of the overhead contact line cable. Since the existing carbon strip is installed at a fixed angle, it cannot dynamically adjust its tilt angle according to the thickness of the ice layer on the surface of the overhead contact line, resulting in a reduced contact area and uneven distribution of contact pressure. This not only seriously affects the current conduction efficiency, causing unstable power supply to the train and leading to operational failures, but also causes local wear to intensify between the carbon strip and the overhead contact line cable. Long-term wear not only significantly shortens the service life of the carbon strip, increases maintenance costs and replacement frequency, and affects the continuity of railway operation, but the debris generated by wear may also pollute the surrounding environment and may even cause serious safety accidents such as short circuits, posing a great threat to the safety and reliability of railway transportation. At the same time, during the sliding process, loose snow particles are compacted to form denser ice nodules, increasing running resistance. Utility Model Content

[0005] The purpose of this invention is to provide an intelligent loop forming device for railway signaling engineering to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A smart loop forming device for railway signaling engineering includes a base frame, a pantograph structure fixedly connected to the outer wall of the base frame, and a mounting bracket for easy installation and fixing of the pantograph structure fixedly installed at the bottom of the base frame.

[0008] The pantograph structure consists of a lower arm, an upper arm, and a pantograph head. One end of the lower arm is fixedly connected to the outer wall of the base frame, and the other end of the lower arm is rotatably connected to the upper arm. The top of the upper arm is rotatably connected to the pantograph head. A carbon sliding plate is installed above the pantograph head, and an adjustment structure for driving the carbon sliding plate to adjust its tilt angle is fixedly installed between the two. A cleaning structure for removing ice and snow from the surface of the contact wire cable is fixedly installed inside the pantograph head.

[0009] As a further embodiment of this utility model, the adjustment structure includes two bending plates, each fixedly installed on both sides of the inner side of the bow head. A connecting shaft is rotatably connected to the interior of each bending plate. One end of the connecting shaft passes through a bending plate and is fixedly fitted with a connecting block. A base plate for supporting the carbon sliding plate is fixedly connected to the upper surface of the connecting block, and the carbon sliding plate is fixedly connected to the base plate. When the carbon sliding plate comes into contact with a contact wire cable containing ice and snow, the carbon sliding plate itself is squeezed by the protruding end of the ice and snow, causing it to drive the base plate and connecting block to rotate around the connecting shaft, generating a tilt angle, thereby achieving self-adjustment of the tilt angle.

[0010] As a further embodiment of this utility model, a bent plate is inserted through the end of the connecting shaft away from the connecting block and a rotating strip is fixedly sleeved thereon, and a connecting rod for buffering is slidably connected to one side of the outer wall of the rotating strip.

[0011] As a further embodiment of this utility model, a spring for resetting is fixedly connected to the other side of the outer wall of the rotating bar. The elastic force generated by the spring's stretching or compression can assist the movement of the carbon slide plate or play a role in buffering and resetting.

[0012] As a further embodiment of this utility model, two sets of limiting rods are fixedly connected to the outer surface of the bending plate, and both sets of limiting rods are located below the rotating bar, thereby limiting the left and right rotation range of the carbon slide plate.

[0013] As a further embodiment of this utility model, the cleaning structure includes a fixing block, and a plurality of fixing blocks are provided and fixedly installed inside the bow head. A transmission rod is rotatably connected to the outer wall of each fixing block, and one end of the transmission rod passes through the bow head and is rotatably connected to a scraper for scraping ice and snow.

[0014] As a further embodiment of this utility model, the bottom surface of the base plate is rotatably mounted with multiple drive rods for pushing the transmission rod to rotate. Each drive rod has a pressing block fixedly installed at its bottom end, and the bottom end of each pressing block is in contact with the top end of the transmission rod.

[0015] As a further embodiment of this utility model, a balance bar is installed below each of the transmission rods to ensure that the scraper always adheres to the contact wire cable. One end of the balance bar is rotatably connected to the fixing block, and the other end is rotatably connected to the scraper for fixing.

[0016] As a further embodiment of this utility model, a drive cylinder for providing power for moving the upper arm is fixedly installed on the upper surface of the base frame, and the output end of the drive cylinder is fixedly connected to the upper arm.

[0017] As a further embodiment of this utility model, a supporting insulator for insulating from the locomotive body is fixedly installed on the top surface of the mounting frame, and the top of the supporting insulator is fixedly connected to the bottom surface of the underframe.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. In use, this utility model, through the setting of an adjustment structure, allows the carbon sliding plate to automatically adjust its tilt angle according to the ice and snow compression on the surface of the contact wire cable. This effectively increases the contact area between the carbon sliding plate and the contact wire cable, ensuring uniform distribution of contact pressure and significantly improving current conduction efficiency. Compared with carbon strips installed at a fixed angle, it can reduce the risk of unstable train power supply, reduce operational failures caused by power supply problems, and ensure the continuity and safety of railway transportation. It also avoids excessive local wear between the carbon sliding plate and the contact wire cable, reducing the generation of wear debris and lowering the possibility of serious safety accidents such as short circuits caused by debris. Furthermore, by promptly removing ice and snow from the surface of the contact wire cable, it prevents loose snow particles from being compacted into ice nodules, reducing train running resistance and further improving the safety of railway transportation.

[0020] 2. When this utility model is in use, the cleaning structure can automatically start and adjust the movement range of the scraper according to the tilt angle of the carbon sliding plate, so as to remove ice and snow on the surface of the contact wire cable in a timely manner, effectively reduce the corrosion of the carbon sliding plate and the contact wire cable by ice and snow, reduce the risk of equipment damage caused by ice and snow accumulation, avoid the aggravation of local wear due to poor contact, extend the service life of the carbon sliding plate, reduce additional cleaning and maintenance work, further reduce operation and maintenance costs, reduce the replacement frequency of the carbon sliding plate, and ensure the continuity of railway operation.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1: Please refer to Figure 1 , Figure 2 A smart ring-forming device for railway signaling engineering includes a base frame 1, a pantograph structure fixedly connected to the outer wall of the base frame 1, and a mounting frame 3 for easy installation and fixing of the pantograph structure fixedly installed at the bottom of the base frame 1.

[0031] The pantograph structure consists of a lower arm 201, an upper arm 202, and a pantograph head 203. One end of the lower arm 201 is fixedly connected to the outer wall of the base frame 1, and the other end of the lower arm 201 is rotatably connected to the upper arm 202 through a connector. The top end of the upper arm 202 is rotatably connected to the pantograph head 203 through a connector. A carbon sliding plate 204 is installed above the pantograph head 203, and an adjustment structure for driving the carbon sliding plate 204 to adjust its tilt angle is fixedly installed between the two. A cleaning structure for removing ice and snow from the surface of the contact wire cable is fixedly installed inside the pantograph head 203.

[0032] Specifically, the carbon sliding plate 204 directly contacts the contact wire cable and is responsible for conducting current. The adjustable structure fixed between the two can automatically adjust the tilt angle of the carbon sliding plate 204 according to the actual contact situation, thereby optimizing the contact effect with the contact wire cable and improving the stability and efficiency of current conduction (the pantograph structure is existing technology, and the specific structure will not be described in detail here).

[0033] Please see Figures 3-6 The adjustment structure includes two bending plates 501, each fixedly installed on both sides of the bow head 203 by bolts. A connecting shaft 502 is rotatably connected inside each bending plate 501. One end of the connecting shaft 502 passes through the bending plate 501 and is fixedly fitted with a connecting block 503. A base plate 504 for supporting the carbon sliding plate 204 is fixedly connected to the upper surface of the connecting block 503 by bolts. The carbon sliding plate 204 is fixedly connected to the base plate 504. When the carbon sliding plate 204 contacts the contact wire cable with ice and snow on its surface, the carbon sliding plate 204 is squeezed by the protruding end of the ice and snow, causing it to rotate around the connecting shaft 502, generating a tilt angle. This achieves self-adjustment of the tilt angle, ensuring good contact between the carbon sliding plate 204 and the contact wire cable.

[0034] Specifically, the top of the connecting block 503 protrudes from the upper surface of the bow head 203, thereby connecting to the lifting base plate 504, so that there is a gap between the base plate 504 and the bow head 203, providing adjustment space for the subsequent rotation of the carbon slide plate 204, avoiding the inability to rotate due to insufficient space, thereby ensuring that the carbon slide plate 204 adapts to the surface condition of the contact wire cable, maintains good contact with the contact wire cable, and ensures the stability of current conduction;

[0035] A bent plate 501 is inserted through the end of the connecting shaft 502 away from the connecting block 503 and a rotating bar 505 is fixedly sleeved thereon. A connecting rod 506 for buffering is slidably connected to one side of the outer wall of the rotating bar 505 by bolts.

[0036] On the other side of the outer wall of the rotating bar 505, a spring 507 for resetting is fixedly connected by a fixing bolt. The elastic force generated by the stretching or compression of the spring 507 can assist the movement of the carbon slide plate 204 or play a role in buffering and resetting.

[0037] Specifically, a crossbar 508 for fixing and supporting the spring 507 is fixedly connected to the side of the connecting rod 506 near the spring 507, and the bottom end of the spring 507 is fixedly connected to the crossbar 508 by a fixing bolt.

[0038] More specifically, both the upper and lower ends of the connecting rod 506 are provided with moving grooves. Two sets of bolts are slidably connected inside the connecting rod 506, and the two sets of bolts are located in the two moving grooves respectively. The bolt at the upper end of the connecting rod 506 is fixedly connected to the rotating bar 505, and the bolt at the lower end of the connecting rod is fixedly connected to the bending plate 501.

[0039] When the carbon skateboard 204 is compressed by ice and snow, causing the base plate 504 and connecting block 503 to tilt to the left, the connecting shaft 502 controls the rotating bar 505 to follow suit and rotate to the left. This, in turn, pushes the connecting rod 506 downward through the bolt at the upper end of the connecting rod 506. Simultaneously, the crossbar 508 on one side of the connecting rod 506 pulls the spring 507 downward, using the elastic force generated by the tension to provide power for the subsequent reset of the carbon skateboard 204. Conversely, when the carbon skateboard 204 tilts to the right, the rotating bar 505 rotates and tilts to the right, thus compressing the spring 507 downward. At this time, the rotating bar 505 causes the upper bolt to disengage from the moving groove until the spring 507 releases pressure and pushes the rotating bar 505 back to its reset position. The upper bolt then returns to the moving groove (see details). Figure 5 );

[0040] Two sets of limiting rods 509 are fixedly connected to the outer surface of the bending plate 501, and both sets of limiting rods 509 are located below the rotating bar 505. By using the two sets of limiting rods 509 to limit the left and right rotation of the carbon slide plate 204, it can prevent the rotating bar 505 from rotating excessively, thereby avoiding excessive tilting of the carbon slide plate 204, effectively preventing the carbon slide plate 204 from losing contact with the contact wire cable, ensuring stable current transmission, and at the same time avoiding damage to the carbon slide plate 204 itself due to excessive rotation, extending the service life of the equipment, and ensuring the stable and safe operation of the railway signaling system in complex environments.

[0041] Example 2: Please refer to Figure 3 , Figure 4 , Figure 7 Based on Embodiment 1, the cleaning structure includes a fixing block 601. Multiple fixing blocks 601 are provided and are all fixedly installed inside the bow head 203. The outer wall of each fixing block 601 is rotatably connected to a transmission rod 602 via a pin. One end of the transmission rod 602 passes through the bow head 203 and is rotatably connected to a scraper 603 for scraping ice and snow.

[0042] Specifically, multiple transmission rods 602 are provided and are equidistantly distributed in an even-number symmetrical pattern inside the bow head 203. The two adjacent transmission rods 602 are staggered to effectively avoid uneven force distribution, ensure the stability and reliability of the cleaning structure during operation, help reduce interference and jamming during transmission, improve transmission efficiency, and ensure that the cleaning structure can work efficiently and continuously.

[0043] More specifically, there are two scrapers 603, which are symmetrically and evenly distributed on both sides of the bow head 203;

[0044] The bottom surface of the base plate 504 is rotatably mounted with multiple drive rods 604 for pushing the transmission rod 602 to rotate via a connector. Each drive rod 604 has a pressing block 605 fixedly installed at its bottom end, and the bottom end of each pressing block 605 is in contact with the top end of the transmission rod 602.

[0045] Specifically, the drive rod 604 is located above the transmission rod 602. When the carbon slide plate 204 is squeezed by ice and snow, it causes the base plate 504 to rotate and tilt to one side. The drive rod 604 at the bottom of the base plate 504 moves down accordingly, which in turn causes the pressing block 605 to press down the transmission rod 602. This causes the end of the transmission rod 602 away from the pressing block 605 to push the scraper 603 upward, thereby removing the ice and snow from the surface of the contact wire cable. This effectively adjusts the movement range of the scraper 603 according to the rotation and tilt angle of the carbon slide plate 204, promptly removes the ice and snow from the surface of the contact wire cable, reduces the wear and corrosion of the carbon slide plate 204 by ice and snow, extends the service life of the equipment, and reduces maintenance costs and replacement frequency.

[0046] Below each drive rod 602 is a balance rod 606 to ensure that the scraper 603 always adheres to the contact wire cable. One end of the balance rod 606 is rotatably connected to the fixing block 601 via a pin, and the other end is rotatably connected to the scraper 603 via a pin. By rotating the balance rod 606 along with the position of the drive rod 602, the angle of the scraper 603 can be flexibly adjusted to ensure that it always adheres to the surface of the contact wire cable and maintains a good cleaning state. At the same time, the balance rod 606 can distribute the pressure on the scraper 603 during operation, preventing the scraper 603 from shaking or shifting due to uneven force, ensuring a smooth and orderly cleaning process, avoiding the impact of scraper 603 shaking on the cleaning effect, and reducing the risk of power failure due to incomplete cleaning.

[0047] Please see Figure 1 , Figure 2 A drive cylinder 205 for providing the moving power of the upper arm 202 is fixedly installed on the upper surface of the base frame 1, and the output end of the drive cylinder 205 is fixedly connected to the upper arm 202 through a connector.

[0048] The top surface of the mounting frame 3 is fixedly equipped with a support insulator 4 for insulation from the locomotive body, and the top of the support insulator 4 is fixedly connected to the bottom surface of the underframe 1. The support insulator 4 plays the role of electrical insulation, preventing current leakage to the locomotive body and ensuring operational safety.

[0049] The working principle of this utility model is as follows:

[0050] First, the drive cylinder 205 is started, pushing the output end to move the upper arm 202, raising the bow head 203, so that the carbon slide plate 204 contacts the contact wire cable, establishing a current conduction path to power the locomotive. Together with the support insulator 4, the device achieves electrical insulation between itself and the locomotive body, preventing current leakage.

[0051] When the carbon sliding plate 204 comes into contact with the contact wire cable covered with ice and snow, the pressure of the protruding end of the ice and snow pushes the carbon sliding plate 204. Since the carbon sliding plate 204 is fixed to the base plate 504, and the base plate 504 is connected to the connecting shaft 502 through the connecting block 503, the carbon sliding plate 204 drives the base plate 504 and the connecting block 503 to rotate around the connecting shaft 502 as the center, thereby adjusting the tilt angle of the carbon sliding plate 204 to ensure good contact with the contact wire cable and maintain stable current conduction.

[0052] Simultaneously, when the connecting shaft 502 rotates, it drives the rotating bar 505 to tilt synchronously. The rotating bar 505 pushes the connecting rod 506 to move through the bolt on the connecting rod 506. When the carbon slide plate 204 tilts to the left, the crossbar 508 on one side of the connecting rod 506 pulls the spring 507 downward to store elastic potential energy, providing power for the carbon slide plate 204 to reset. Conversely, when the carbon slide plate 204 tilts to the right, the rotating bar 505 squeezes the spring 507, causing the upper bolt to disengage from the moving groove. The spring 507 releases pressure and pushes the rotating bar 505 to reset. The bolt returns to the moving groove again. In conjunction with the limiting rod 509 on the bending plate 501, the rotation amplitude of the rotating bar 505 is limited to prevent the carbon slide plate 204 from tilting excessively and to prevent it from detaching from the contact wire cable, thus protecting the carbon slide plate 204.

[0053] Finally, when the carbon sliding plate 204 is squeezed by ice and snow, causing the base plate 504 to rotate and tilt, the drive rod 604 at the bottom of the base plate 504 moves down accordingly, and the pressing block 605 at the bottom of the drive rod 604 presses down the transmission rod 602. Since one end of the transmission rod 602 is rotatably connected to the fixed block 601, after being pressed, the other end pushes the scraper 603 upward to scrape off the ice and snow on the surface of the contact wire cable.

[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
