Description

Technical Field

[0001] The present invention belongs to the technical field of subway track detection equipment, and specifically relates to a positioning detection device for subway power supply installation. Background Art

[0002] As an important part of modern urban transportation, the subway is a rapid, high-capacity, and electrically powered rail transit system built in cities. Its trains run on fully enclosed lines, which not only ensures the safety of train operation but also efficiently avoids ground traffic interference, greatly improving the traffic efficiency. In the subway system, electric locomotives obtain electrical energy by contacting the contact rail with pantographs. This power supply method directly determines the stability and reliability of train operation. If the installation quality of the contact rail does not meet the design specifications, it will cause problems such as poor contact and increased wear, resulting in the abnormal operation of the traction power supply system. This not only affects the punctuality rate and operation efficiency of subway trains but may also cause train delays, outages, etc., seriously interfering with the daily travel of urban residents and even threatening public traffic safety. Therefore, ensuring that the installation quality of the contact rail meets the standards is crucial for ensuring the safe and efficient operation of the subway.

[0003] The existing traditional fixed-point installation and detection of contact rails mainly rely on staff using track gauges to measure point by point. This manual detection method has many drawbacks: First, it requires a large amount of manpower, consuming a lot of time and energy, and long-term repetitive work is likely to cause staff fatigue, affecting the measurement accuracy. Second, the detection efficiency is low, making it difficult to meet the timeliness requirements of subway engineering construction or maintenance. Especially during large-scale line detection, it will seriously slow down the project progress. Third, even if an unqualified contact rail installation is found, there is a lack of fast and accurate marking means, making it difficult to quickly locate the problem area, increasing the difficulty and time cost of subsequent correction operations. It may even lead to secondary detection or incorrect repair due to untimely and inaccurate marking, further reducing work efficiency and increasing maintenance costs, and it is difficult to meet the requirements of high-efficiency operation and maintenance in the rapid development of modern rail transit. Therefore, improvement and optimization are needed. Summary of the Invention

[0014] 1. By sequentially starting the controller and the lifting assembly, the present invention realizes precise control of the height lifting of the components of the detection box, ensuring that the monitoring reference plate provided at the end of the detection connection plate can accurately correspond to and contact the contact rail. Secondly, after the cylinder is started, it drives the relevant components to act, and in cooperation with the elastic recovery of the spring and the magnetic attraction between the magnetic attraction groove and the magnetic attraction protrusion, it effectively avoids shaking and guarantees the stability of the detection. Furthermore, the detection connection plate drives the positioning detection device to perform positioning detection on the contact rail.

[0015] 2. Firstly, the controller starts the power pump to achieve precise pumping of the paint. The paint is pumped out from the inside of the storage tank to the delivery hose, ensuring the efficient delivery of the marking raw material and avoiding waste. Secondly, the linkage design between the detection box and the marking component enables the marking device to be lifted and lowered synchronously with the detection components, ensuring that the marking position is highly adapted to the detection situation of the contact rail and improving the marking accuracy. Thirdly, the connection design between the delivery hose and the spraying head precisely coats the paint on the contact rail that does not meet the positioning and installation requirements, clearly marking the problem areas and providing an intuitive guide for subsequent repair and adjustment, reducing the cost of repeated detection and repair. Fourthly, the sealing cover is threadedly connected to the top of the storage tank, facilitating the replenishment of raw materials and ensuring the continuous and efficient progress of the marking work.

[0016] 3. The controller starts the hydraulic cylinder, which can achieve precise control of the lifting of the transmission plate. The design of the slider sliding inside the rectangular groove effectively guarantees the stability of the transmission plate during the lifting process, avoiding affecting the detection accuracy due to shaking. The linkage between the transmission plate and the lifting rod drives the detection component and the marking component to be lifted and lowered synchronously, ensuring that the detection device can flexibly adjust the height and precisely fit different positions of the contact rail. This hierarchical linkage design enables the equipment to perform all-round positioning detection on the contact rail efficiently and stably, greatly improving the accuracy and reliability of the detection work.

Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of 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.

[0026] As Figures 1 to 7As shown in the figure, the embodiment of the present invention provides a positioning detection device for subway power supply installation, which includes a support assembly 1, a support frame 3 and a support plate 4. A track wheel 2 is rotatably installed inside the support assembly 1. A lifting assembly 5 is fixedly installed on the bottom side of the support plate 4. A detection assembly 6 is arranged at the end of the lifting assembly 5. The detection assembly 6 includes a detection box 601 fixedly installed at the end of the lifting assembly 5. A first chute 602 is opened inside the detection box 601. A connection box 603 is fixedly installed on one side of the detection box 601. A second protective shell 604 is fixedly installed on the right side of the connection box 603. A cylinder 605 is fixedly installed inside the second protective shell 604 and the output end of the cylinder 605 extends to the inside of the connection box 603. A transmission block 606 is fixedly installed at the end of the output shaft of the cylinder 605. An activity groove 609 is opened on the outer surface of the connection box 603. A limit support 610 is fixedly installed at the top of the transmission block 606. A detection connection plate 615 is slidably installed inside the first chute 602. A slide bar 613 is fixedly installed inside the first chute 602 and both ends of the slide bar 613 penetrate through the inside of the detection connection plate 615 and the detection connection plate 615 is located inside the limit support 610. A magnetic attraction groove 611 is opened inside the detection connection plate 615. A magnetic attraction convex block 612 is fixedly installed inside the limit support 610 and is in magnetic attraction fit with the magnetic attraction groove 611 and the end of the limit support 610 is in a C-shaped shape. A positioning detection device 616 is fixedly installed at one end of the detection connection plate 615. A marking assembly 7 is fixedly installed on the side of the detection box 601. A controller 8 is fixedly installed on the top of the support assembly 1.

[0027] When the work starts the lifting assembly 5 through the controller 8, then the lifting assembly 5 will drive the detection boxes 601 on both sides to rise and fall in height. When the lifting assembly 5 drives the detection box 601 to rise and fall, it will drive the detection connection plate 615 to rise and fall. When the monitoring reference plate arranged at the end of the detection connection plate 615 corresponds to the contact rail, at this time, the cylinder 605 is started through the controller 8. When the cylinder 605 is started, the output end will drive the transmission block 606 to gradually move away from the second protective shell 604. At the same time, the transmission block 606 will drive the C-shaped clamp block at the end of the limit support 610 to gradually move away from the second protective shell 604. At the same time, the springs 614 on both sides will push the detection connection plate 615 away from the second protective shell 604 through the elastic recovery effect. Since the magnetic attraction groove 611 and the magnetic attraction convex block 612 are magnetically attracted and fitted with each other, during the movement process, the situation of excessive shaking is avoided. Then the detection connection plate 615 will drive the positioning detection device 616 to perform positioning detection on the contact rail of the subway power supply. After that, observe the distance reading on the controller 8 and compare it with the designed standard spacing of the contact rail, and then it can be judged whether the distance between the two contact rails meets the installation standard. When it does not meet the standard, the marking assembly 7 will be controlled by the controller 8 to mark the non-compliant contact rail.

[0028] Through the orderly start controller 8 and the lifting assembly 5, precise control over the height lifting of the components of the detection box 601 is achieved, ensuring that the monitoring reference plate provided at the end of the detection connecting plate 615 can accurately correspond to the contact rail. Secondly, after the cylinder 605 is started, it drives related components to act, and in cooperation with the elastic recovery of the spring 614 and the magnetic attraction between the magnetic attraction groove 611 and the magnetic attraction bump 612, shaking is effectively avoided, guaranteeing the stability of the detection. Furthermore, the detection connecting plate 615 drives the positioning detection device 616 to perform positioning detection on the contact rail. By comparing the distance reading on the controller 8 with the design standard, it can quickly and accurately determine whether the spacing meets the standard. Finally, the marking assembly 7 can be controlled by the controller 8 to mark, which is convenient for subsequent adjustment, greatly improving the efficiency and accuracy of detection and maintenance.

[0029] Among them, the marking assembly 7 includes a storage tank 701 fixedly installed on the side of the detection box 601. A pump bracket 703 is fixedly installed on the outer surface of the storage tank 701. A power pump 704 is fixedly installed on the top of the pump bracket 703, and one end of the power pump 704 extends to the inside of the storage tank 701. A connecting plate 705 is fixedly installed on one side of the detection connecting plate 615. A spray head 707 is fixedly installed on the outer surface of the connecting plate 705. The output end of the power pump 704 and the spray head 707 are interconnected through a delivery hose 706. A sealing cover 702 is threadedly connected to the top of the storage tank 701.

[0030] When the controller 8 starts the power pump 704, it will cause one end of the power pump 704 to pump out the marking paint from the inside of the storage tank 701 and pump it into the delivery hose 706. At the same time, the detection box 601 moves up and down, driving the marking assembly 7 up and down. Then the delivery hose 706 is interconnected with the spray head 707. After that, the spray head 707 will apply the marking paint on the contact rail that does not meet the positioning installation, avoiding re-repair and adjustment. At the same time, a sealing cover 702 is threadedly connected to the top of the storage tank 701, facilitating the addition of raw materials to the storage tank 701.

[0031] Firstly, the controller 8 starts the power pump 704 to achieve precise pumping of the paint, pumping the paint from the inside of the storage tank 701 to the delivery hose 706, ensuring the efficient delivery of the marking raw materials and avoiding waste. Secondly, the linkage design between the detection box 601 and the marking assembly 7 enables the marking device to move up and down synchronously with the detection components, ensuring that the marking position is highly adapted to the detection situation of the contact rail and improving the marking accuracy. Thirdly, the connection design between the delivery hose 706 and the spray head 707 accurately applies the paint on the contact rail that does not meet the positioning installation, clearly marking the problem area, providing an intuitive guide for subsequent repair and adjustment, and reducing the cost of repeated detection and repair. Fourthly, the sealing cover 702 is threadedly connected to the top of the storage tank 701, facilitating the replenishment of raw materials and ensuring the continuous and efficient progress of the marking work.

[0032] Among them, the lifting assembly 5 includes a first protective shell 506 fixedly installed on the bottom side of the support plate 4, a hydraulic cylinder 501 fixedly installed on the inner side of the first protective shell 506, the output end of the hydraulic cylinder 501 passes through the support plate 4, and the output end of the hydraulic cylinder 501 is fixedly installed with a transmission plate 502. Rectangular grooves 504 are opened on each side of each side of the support frame 3, and sliders 505 are fixedly installed on both sides of the transmission plate 502 and extend to the inside of the rectangular groove 504. Lifting rods 503 are fixedly installed on both sides of the top of the transmission plate 502, and the ends of the lifting rods 503 pass through the support frame 3, and the ends of the lifting rods 503 are fixedly installed with detection boxes 601.

[0033] When the controller 8 starts the hydraulic cylinder 501, the output end of the hydraulic cylinder 501 will drive the transmission plate 502 to rise and fall. At the same time, when the transmission plate 502 rises and falls, it will drive the slider 505 to slide inside the rectangular groove 504 to keep the transmission plate 502 stable. When the transmission plate 502 rises and falls, it will drive the lifting rod 503 to rise and fall. When the lifting rod 503 rises and falls, it will drive the detection component 6 and the marking component 7 to rise and fall, thereby facilitating the positioning detection of the contact rail.

[0034] By starting the hydraulic cylinder 501 through the controller 8, precise control of the lifting and lowering of the transmission plate 502 can be achieved, and the design of the slider 505 sliding inside the rectangular groove 504 effectively ensures the stability of the lifting process of the transmission plate 502, avoiding the impact of shaking on the detection accuracy. The linkage between the transmission plate 502 and the lifting rod 503 drives the detection component 6 and the marking component 7 to rise and fall synchronously, ensuring that the detection device can flexibly adjust the height and accurately fit the different positions of the contact rail. This hierarchical linkage design enables the equipment to perform all-round positioning detection of the contact rail efficiently and stably, greatly improving the accuracy and reliability of the detection work.

[0035] A stabilizing rod 9 is fixedly installed between the supporting plate 4 and the supporting frame 3 , and both ends of the stabilizing rod 9 pass through the interior of the transmission plate 502 .

[0036] By having both ends of the stabilizing rod 9 pass through the interior of the transmission plate 502 and having two stabilizing rods 9 on both sides of the hydraulic cylinder 501 , the transmission plate 502 can be kept balanced when it is raised or lowered, thus avoiding jamming.

[0037] A slide groove 607 is provided on the inner side of the connection box 603 , and a ball 608 is rotatably mounted on the bottom of the transmission block 606 and is located inside the slide groove 607 .

[0038] When the transmission block 606 is driven to move by the output end of the cylinder 605, the ball 608 will be driven to roll inside the slide groove 607, and then the stability of the transmission block 606 when driving the limiting bracket 610 to move can be maintained.

[0039] Among them, the track wheel 2 is rotatably installed inside the support assembly 1, and there are two track wheels 2 rotatably installed on the inner side of the support assembly 1 and the two track wheels 2 do not contact each other.

[0040] Since there are two track wheels 2 rotatably installed on the inner side of the support assembly 1 and the two track wheels 2 do not contact each other, it is convenient for the entire detection device to move on the track.

[0041] Among them, a stabilizing bracket 10 is fixedly installed between the support assembly 1 and the support frame 3, and the stabilizing bracket 10 is triangular in shape.

[0042] By fixedly installing the stabilizing bracket 10 between the support assembly 1 and the support frame 3, the structural firmness of the entire detection device can be effectively increased.

[0043] Among them, a support frame 3 is fixedly installed between the two support assemblies 1, and the support frame 3 is C-shaped. A support plate 4 is fixedly installed between the inner sides of the support frame 3.

[0044] By fixedly installing the support plate 4 between the inner sides of the support frame 3, a stable support effect can be effectively provided for the lifting assembly 5.

[0045] Working principle and usage process:

[0046] When the work starts the lifting assembly 5 through the controller 8, then the lifting assembly 5 will drive the detection boxes 601 on both sides to lift in height. When the lifting assembly 5 drives the detection box 601 to lift, it will drive the detection connection plate 615 to lift. When the monitoring reference plate provided at the end of the detection connection plate 615 corresponds to the contact rail, at this time, the cylinder 605 is started through the controller 8. When the cylinder 605 is started, the output end will drive the transmission block 606 to gradually move away from the second protective shell 604. At the same time, the transmission block 606 will drive the C-shaped clamp block at the end of the limit bracket 610 to gradually move away from the second protective shell 604. At the same time, the springs 614 on both sides will push the detection connection plate 615 away from the second protective shell 604 through the elastic recovery effect. Since the magnetic attraction grooves 611 and the magnetic attraction bumps 612 are magnetically attracted and fitted to each other, during the movement process, the situation of excessive shaking can be avoided. Then the detection connection plate 615 will drive the positioning detection device 616 to perform positioning detection on the contact rail for subway power supply. After that, observe the distance reading on the controller 8 and compare it with the designed standard spacing of the contact rail to determine whether the distance between the two contact rails meets the installation standard. When it does not meet the standard, the controller 8 will control the marking assembly 7 to mark the non-compliant contact rail.

[0047] When the controller 8 starts the power pump 704, one end of the power pump 704 will pump out the marking paint from the inside of the storage tank 701 and pump it into the conveying hose 706. At the same time, the upper and lower parts of the detection box 601 will drive the marking assembly 7 up and down. Then the conveying hose 706 will communicate with the spraying head 707. After that, the spraying head 707 will apply the marking paint on the contact rail that does not meet the positioning and installation requirements, avoiding the need for re-repair and adjustment. At the same time, the top of the storage tank 701 is threadedly connected with a sealing cover 702, which is convenient for adding raw materials to the storage tank 701.

[0048] When the controller 8 starts the hydraulic cylinder 501, the output end of the hydraulic cylinder 501 will drive the transmission plate 502 to move up and down. At the same time, when the transmission plate 502 moves up and down, it will drive the slider 505 to slide inside the rectangular groove 504 to keep the transmission plate 502 stable during its up and down movement. When the transmission plate 502 moves up and down, it will drive the lifting rod 503 to move up and down. When the lifting rod 503 moves up and down, it will drive the detection assembly 6 and the marking assembly 7 to move up and down, so as to facilitate the positioning and detection of the contact rail.
