Description

Technical Field

[0001] The present invention relates to the technical field of track laying tools, and particularly relates to a rail laying device for railway construction. Background Art

[0002] In actual track laying work, currently, the track to be laid is mainly towed by a tractor to the track fasteners on the sleepers for installation. During this process, workers will place a drag reduction roller under the track, and then remove the drag reduction roller and tighten the bolts of the track fasteners. Usually, the bolts need to be tightened at intervals. Currently, the rail laying device for railway construction mainly relies on manual observation to determine that one track fastener bolt is tightened every three sleepers. This manual operation is prone to omission. When manually operating the fastener tightening device to tighten the four fastener bolts on both sides of the track simultaneously, due to insufficient observation, the quality of track tightening is affected, which has an impact on the subsequent adjustment and stress of the track. It is also easy for the bolt to slip off the wrench, further damaging the fastener bolt. It is not convenient for in-place detection, and it is also not convenient to detect the removal of the drag reduction roller before track installation. When the fastener bolt is directly tightened without removing the drag reduction roller, since the drag reduction roller needs to support the track and its height is higher than the support height of the track fastener, directly tightening the fastener bolt will directly cause extrusion deformation damage to the track, affecting the track accuracy and even scrapping it.

[0003] Therefore, the present application provides a rail laying device for railway construction to meet the requirements. Summary of the Invention

[0040] As Figures 3 to 5As shown, the laying and installation part 1 further includes four rollers 103 rotatably installed on both sides of the movable counterweight plate 101; annular grooves 1031 are respectively provided on the four rollers 103, and the four annular grooves 1031 are respectively used for rolling and fitting on the track; an indicator light 104 is installed on the movable counterweight plate 101; the lifting adapter 2 includes a lifting column 201 slidably installed on the movable counterweight plate 101; the lifting column 201 is of a hexagonal column structure; a downward pressure spring 202 is sleeved on the lifting column 201; a fixed connection plate 203 is fixedly installed on the lifting column 201; the end of the downward pressure spring 202 is connected to the movable counterweight plate 101; the other end of the downward pressure spring 202 is connected to the fixed connection plate 203; a in-place indicator light 204 is fixedly installed on the fixed connection plate 203; a lifting toggle rod 205 is fixedly installed on the fixed connection plate 203, and the end of the lifting toggle rod 205 is located above the hand-held frame 102; two guiding blocks 206 are fixedly installed at the bottom of the fixed connection plate 203, and the front ends of the bottoms of the two guiding blocks 206 are respectively of a bevel structure; the two guiding blocks 206 are respectively used for sliding over the track fastener bolts; the two guiding blocks 206 are respectively located on both sides of the two rollers 103 on the same side; the bolt tightening part 3 includes a tightening driving motor 301 fixedly installed on the fixed connection plate 203; the output shaft of the tightening driving motor 301 passes through the fixed connection plate 203; an internal hexagonal socket 302 is fixedly installed on the output shaft of the tightening driving motor 301; an in-place microswitch 303 is fixedly installed inside the internal hexagonal socket 302; the in-place microswitch 303 is used to detect the docking of the internal hexagonal socket 302 with the track fastener bolt; the bottom of the internal hexagonal socket 302 is flush with the bottom of the guiding block 206; the inner circle of the bottom of the internal hexagonal socket 302 is chamfered; the in-place indicator light 204 is electrically connected to the in-place microswitch 303. The bolt tightening part 3 can facilitate the staff to quickly tighten the fastener bolts. At the same time, in cooperation with the lifting adapter 2, it is not necessary for the staff to manually align the bolts each time, which is more convenient for automatically sleeving the bolts for tightening, improving the bolt tightening speed and the track laying and installation efficiency. At the same time, this structure can detect the in-place situation of the fastener bolts, avoiding problems such as the loosening of the fastener bolts caused by directly starting the tightening driving motor 301 to drive the internal hexagonal socket 302 to rotate when the fastener bolts are not completely in place. This structure is more reasonable, can ensure the bolt tightening quality, and prevent omission. The rollers 103 used can directly roll on the track to ensure the flexibility of the use of this structure. The bevel structure on the front side of the guiding block 206 can drive the guiding block 206 to move upward under the extrusion of the front fastener bolt. At this time, the lifting column 201 will move upward, stretching the downward pressure spring 202. As the movable counterweight plate 101 continues to be pushed to move, when the internal hexagonal socket 302 moves to the fastener bolt, the internal hexagonal socket 302 will be directly inserted into the fastener bolt under the pulling of the downward pressure spring 202, and the fastener bolt will squeeze the in-place microswitch 303 to control the indicator light 204 to light up to indicate in-place.

[0041] AsFigure 3 , Figures 6 to 8 As shown in Figures 6 to 8 , the interval fastening detection member 4 includes two rotating connection arms 401 fixedly installed at the bottom of the moving counterweight plate 101; a rotating wheel 402 is rotatably installed on the two rotating connection arms 401, and a rubber soft sleeve is provided on the outer side of the rotating wheel 402; the rubber soft sleeve on the outer side of the rotating wheel 402 is used for elastically rolling and fitting the sleeper; four positioning grooves 4021 are provided on the side surface of the rotating wheel 402; the inner sides of the four positioning grooves 4021 are respectively inclined surface structures; an elastic limiting shaft 403 is slidably inserted on the rotating connection arm 401; a tension spring is sleeved on the elastic limiting shaft 403, and the end of the tension spring sleeved on the elastic limiting shaft 403 is connected to the side surface of the rotating connection arm 401, and the other end of the tension spring sleeved on the elastic limiting shaft 403 is connected to the side surface of the elastic limiting shaft 403; the elastic limiting shaft 403 is inserted into the positioning groove 4021 on the same side; the interval fastening detection member 4 further includes a rotating control column 404 fixedly installed on the side surface of the rotating wheel 402; the end of the rotating control column 404 is an arc structure; the interval prompting part 5 includes a detection fixing piece 501 fixedly installed on the side surface of the rotating connection arm 401 located on one side of the rotating control column 404; a power connection elastic piece 502 is fixedly installed on the side surface of the rotating connection arm 401 located on one side of the rotating control column 404; the end of the rotating control column 404 is used for pressing the power connection elastic piece 502, and the power connection elastic piece 502 elastically fits the detection fixing piece 501; the detection fixing piece 501, the pressing power connection elastic piece 502 and the indicator light 104 are connected in series to the power supply. By using the interval fastening detection member 4, it can cooperate with the interval prompting part 5 to automatically detect the number of sleepers passed. Through the light source for prompting, it can ensure that the staff can tighten one fastener bolt every three sleepers passed, and the interval fastening work can be carried out more accurately, avoiding the problems such as rework that the traditional fastening method needs to rely on manual counting and once the counting is wrong. This structure has accurate and direct detection, can improve the accuracy of track fastening, reduce the error rate, and at the same time the prompting method is simple and intuitive. As a track fastener fastening specification, when the train runs, there will be a small displacement between the rail and the sleeper due to the load change. The interval fastening reserves adjustment space for the system, allowing the workers to gradually correct the loose bolts during subsequent inspections, avoiding the loss of flexibility of the overall structure due to one-time locking, especially the elastic differences in the materials of wooden sleepers or concrete sleepers. The interval fastening can avoid local compression deformation of the sleeper caused by over-tightening of unilateral bolts, ensure uniform load transfer to the roadbed. When fastening the fasteners, the gauge and the track level need to be adjusted synchronously. The interval operation allows measurement and correction of deviations section by section, avoiding difficult adjustment after one-time fastening. The rotating wheel 402 will be driven to rotate 90 degrees by friction every time it passes a sleeper, and the corresponding elastic limiting shaft 403 is used to be inserted into the positioning groove 4021 on the same side for elastic fitting and limiting to prevent the rotating wheel 402 from idling. Because there are four positioning grooves 4021, that is, every time four sleepers are passed, the rotating control column 404 returns to the origin, realizing interval control to prompt the indicator light 104 to light up.

[0042] As Figure 3 , Figure 9 and Figure 10 shown, the position-limiting and centering part 6 includes a position-limiting and centering plate 601 fixedly installed at the bottom of the moving counterweight plate 101 through bolts; two L-shaped plates 602 are fixedly installed on the position-limiting and centering plate 601; the two L-shaped plates 602 are symmetrically arranged; the position-limiting and centering part 6 further includes an obstacle switch 603 fixedly installed on the side of the position-limiting and centering plate 601; an obstacle warning lamp 604 is fixedly installed on the position-limiting and centering plate 601; the obstacle warning lamp 604 is electrically connected to the obstacle switch 603; a chute is provided on the front side of the position-limiting and centering plate 601; the anti-deformation insurance part 7 further includes a sliding plug 701 slidably installed in the chute on the front side of the position-limiting and centering plate 601; both sides of the sliding plug 701 are bevel structures; two V-shaped elastic pieces 702 are fixedly installed at the tail of the sliding plug 701, and the ends of the two V-shaped elastic pieces 702 are respectively connected to the inner sides of the two L-shaped plates 602; the sliding plug 701 is aligned with the obstacle switch 603. Using the position-limiting and centering part 6 can facilitate the staff to carry out auxiliary positioning and correction work on the track, improve the track position accuracy, reduce a small amount of deviation that appears locally on the track, and at the same time can improve the centering degree of the track at the two-side fasteners, ensuring the stable installation of the track. Using the anti-deformation insurance part 7 can be used to assist in testing obstacles before fastening the fastener bolts, preventing the resistance-reducing rollers that are not removed or omitted from being removed on the front side from affecting the bolt fastening. Because the resistance-reducing rollers need to support the track, their height is higher than the support height of the track fasteners. If the fastener bolts are directly tightened, the resistance-reducing rollers will directly squeeze and deform to damage the track, causing economic losses and construction period delays. The detection of this structure is direct and reliable, and the staff can intuitively know that the position-limiting and centering plate 601 is always on one side of the fastener base on the same side. The position-limiting and centering plate 601 is limited by the fastener base, and then the four annular grooves 1031 are used to limit the track. As the moving counterweight plate 101 moves, the four annular grooves 1031 can ensure the accurate position of the track in real time. At the same time, when the position-limiting and centering plate 601 moves, when the sliding plug 701 on the front side passes between two sleepers, there should be no obstacles. The corresponding sliding plug 701 uses its bevel structure and will insert into the interval of the fastener base between the two sleepers, and then it will no longer be in contact with the obstacle switch 603, and the obstacle warning lamp 604 can light up to give a warning. On the contrary, if there are obstacles between the two sleepers.

[0043] The working principle of the technical solution provided by the present invention is as follows:

[0044] After the roller 103 is placed on the track, the annular grooves 1031 are respectively used to roll and fit the track. Hold the hand-held frame 102 set by hand and push the movable counterweight plate 101 to move. At this time, the movable counterweight plate 101 can drive the guide block 206 to move together. The front side of the guide block 206 is a bevel structure, and it can be driven to move upward under the extrusion of the front side fastener bolt. At this time, the lifting column 201 will move upward, stretching the downward pressing spring 202. As the movable counterweight plate 101 continues to be pushed to move, when the hexagon socket 302 moves to the fastener bolt, the hexagon socket 302 will be directly inserted into the fastener bolt under the pulling of the downward pressing spring 202. At this time, the staff will obviously feel a sense of blockage when pushing the movable counterweight plate 101 to move. At the same time, when the hexagon socket 302 is inserted into the fastener bolt, the fastener bolt will squeeze the in-place microswitch 303 to control the indicator light 204 to light up to indicate in place. During the process, the tightening drive motor 301 continuously drives the hexagon socket 302 to screw the fastener bolt. When the movable counterweight plate 101 moves, it can drive the rotary wheel 402 to move together. At this time, the rubber soft sleeve provided on the outer side of the rotary wheel 402 will be rubbed by the sleeper and rotate. Each time the rotary wheel 402 passes a sleeper, it will be driven to rotate 90 degrees. The corresponding elastic limit shaft 403 is used to be inserted into the positioning groove 4021 on the same side for elastic fitting and limiting to prevent the rotary wheel 402 from idling. When the rotary wheel 402 rotates, it will drive the rotary control column 404 to rotate together. The rotary control column 404 can squeeze the power connection elastic piece 502 to elastically fit the detection fixing piece 501 to realize the control of the indicator light 104 to light up and prompt. Because there are four positioning grooves 4021, that is, every time the rotary wheel 402 passes four sleepers, the rotary control column 404 returns to the origin to realize the interval control of the indicator light 104 to light up and prompt;As the movable counterweight plate 101 moves, the limit center plate 601 is always on the side of the fastener base on the same side. The limit center plate 601 is limited by the fastener base, and the track is limited by the four annular grooves 1031. As the movable counterweight plate 101 moves, the four annular grooves 1031 can ensure the accuracy of the track position in real time. At the same time, when the limit center plate 601 moves, the front sliding block 701 should be free of obstructions when passing between two sleepers. The corresponding sliding block 701 will use its inclined structure to insert into the fastener base interval between the two sleepers. At this time, the sliding block 701 will no longer fit the obstacle switch 603 under the squeezing of the V-shaped spring piece 702 end, and the obstacle warning light 604 can light up to warn On the contrary, if there is an obstacle between the two sleepers, when the sliding block 701 moves between the two sleepers, the sliding block 701 will be blocked by the undisassembled drag reduction roller, and the V-shaped spring piece 702 will also remain in a compressed state. At this time, the sliding block 701 will be close to the obstacle switch 603, and the obstacle warning light 604 will remain off. Once the staff finds that the obstacle warning light 604 fails to light up between the two sleepers, the problem should be promptly checked. After completing the tightening work of a fastener bolt, the handheld frame 102 can be lifted up to drive the handheld frame 102 to toggle the lifting toggle rod 205, so that the bolt tightening part 3 installed on the lifting column 201 can be lifted and separated from the fastener bolt that has been tightened, and the next bolt tightening work can be continued. ;
