Description

Technical Field

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

[0002] In actual track laying work, the track to be laid is currently mainly towed by a tractor to the track fasteners on the sleepers for installation. During this process, the staff 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. The current rail laying device for railway construction mainly judges by manual observation that one track fastener bolt is tightened every three sleepers. This method is prone to omissions in manual operation. When the manual fastener tightening equipment tightens the four fastener bolts on both sides of the track at the same time, the quality of track tightening is affected due to inadequate observation, which affects the subsequent adjustment and stress of the track, and is also easy to cause the bolts to slip off the wrench, further damaging the fastener bolts, making it inconvenient to perform in-place detection, and it is also inconvenient to disassemble and detect the drag reduction roller before track installation. When the fastener bolts are directly tightened without disassembling the drag reduction roller, because the drag reduction roller needs to support the track, its height is higher than the track fastener support height, directly tightening the fastener bolts will directly cause extrusion deformation damage to the track, affecting the track accuracy, or even scrapping.

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

The anti-deformation insurance part can be used to assist in testing obstacles before the fastener bolts to be tightened, to prevent the drag reduction roller on the front side from being removed or missed to be removed and affecting the tightening of the bolts. Because the drag reduction roller needs to support the track, its height is higher than the support height of the track fastener. If the fastener bolts are directly tightened, the drag reduction roller will directly squeeze and deform to damage the track, causing economic losses and delays in construction.

[0027] like Figures 1 to 10 As shown, an embodiment of the present invention provides a rail laying device for railway construction, including a laying installation part 1, on which two lifting adapter parts 2 are installed, and two bolt tightening parts 3 are respectively installed on the two lifting adapter parts 2; the four bolt tightening parts 3 are respectively used to tighten the rail fastener bolts; the laying installation part 1 is used to move on the rail surface; an interval fastening detection part 4 is installed at the bottom of the laying installation part 1; the interval fastening detection part 4 is used to fit the rail sleepers; an interval prompting part 5 is installed on the interval fastening detection part 4; the interval prompting part 5 is used to prompt the fastening position; two limit center parts 6 are fixedly installed at the bottom of the laying installation part 1; anti-deformation insurance parts 7 are respectively installed on the two limit center parts 6; the anti-deformation insurance part 7 is used to detect the removal of the rail support roller; the laying installation part 1 includes: a movable counterweight plate 101 and a handheld frame 102, and the handheld frame 102 is rotatably installed on the movable counterweight plate 101; the movable counterweight plate 101 is used for counterweighting.

[0028] like Figures 3 to 5As shown, the laying installation part 1 also includes four rollers 103 rotatably installed on both sides of the mobile 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 the track; an indicator light 104 is installed on the mobile counterweight plate 101; the lifting adapter 2 includes a lifting column 201 slidably installed on the mobile counterweight plate 101; the lifting column 201 is a hexagonal column structure; a downward tension spring 202 is sleeved on the lifting column 201; a fixed connecting plate 203 is fixedly installed on the lifting column 201; the end of the downward tension spring 202 is connected to the mobile counterweight plate 101; the other end of the downward tension spring 202 is connected to the fixed connecting plate 203; the fixed connecting plate 203 is fixedly installed There is an in-position prompt light 204; an upper lifting and toggling rod 205 is fixedly installed on the fixed connecting plate 203, and the end of the upper lifting and toggling rod 205 is located above the handheld frame 102; two guide blocks 206 are fixedly installed at the bottom of the fixed connecting plate 203, and the front ends of the bottoms of the two guide blocks 206 are inclined structures; the two guide blocks 206 are used to slide over the track fastener bolts respectively; the two guide 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 drive motor 301 fixedly installed on the fixed connecting plate 203; the output shaft of the tightening drive motor 301 passes through the fixed connecting plate 203; an inner hexagon socket 302 is fixedly installed on the output shaft of the tightening drive motor 301; the inner hexagon socket 302 is fixed inside A micro switch 303 is installed in place; the micro switch 303 is used to detect that the hexagon socket 302 is connected to the track fastener bolt; the bottom of the hexagon socket 302 is flush with the bottom of the guide block 206; the inner circle of the bottom of the hexagon socket 302 is chamfered; the in-place prompt light 204 is electrically connected to the micro switch 303, and the bolt tightening part 3 can be used to facilitate the staff to quickly tighten the fastener bolts. At the same time, with the lifting adapter 2, there is no need for the staff to manually align the bolts every time, which can make it easier to automatically socket the bolts for tightening, thereby increasing the bolt tightening speed and improving the track laying and installation efficiency. At the same time, this structure can detect the fastener bolt in place to avoid directly starting the tightening drive motor 301 when the fastener bolts are not fully in place. The hexagon socket 302 is driven to rotate, causing problems such as the fastener bolts becoming loose. The present structure is more reasonable and can ensure the quality of bolt tightening while preventing omissions. The roller 103 used can roll directly on the track to ensure the flexibility of the present structure. The front inclined surface structure of the guide block 206 can drive the guide block 206 to move upward under the extrusion of the front fastener bolts. At this time, the lifting column 201 will move upward, lengthening the downward pressure spring 202. As the moving 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 pulled by the downward pressure spring 202 and directly inserted into the fastener bolt. The fastener bolt will squeeze the micro switch 303 into place, and the control indicator light 204 will light up to indicate that it is in place.

[0029] like Figure 3 , Figures 6 to 8 As shown, the interval fastening detection member 4 includes two rotating connecting arms 401 fixedly installed at the bottom of the movable counterweight plate 101; a rotating wheel 402 is rotatably installed on the two rotating connecting 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 elastic rolling and fitting the sleeper; four positioning grooves 4021 are opened on the side of the rotating wheel 402; the inner sides of the four positioning grooves 4021 are inclined structures respectively; an elastic limiting shaft 403 is slidably inserted on the rotating connecting arm 401; a tension spring is sleeved on the elastic limiting shaft 403, and the elastic The end of the tension spring sleeved on the limit shaft 403 is connected to the side of the rotating connecting arm 401, and the other end of the tension spring sleeved on the elastic limit shaft 403 is connected to the side of the elastic limit shaft 403; the elastic limit shaft 403 is inserted into the positioning groove 4021 on the same side; the interval fastening detection member 4 also includes a rotation control column 404 fixedly installed on the side of the rotating wheel 402; the end of the rotation control column 404 is an arc-shaped structure; the interval prompting part 5 includes a detection fixing piece 501 fixedly installed on the side of the rotating connecting arm 401 located on one side of the rotation control column 404; the detection fixing piece 501 located on the rotation control column 40 The side of the rotating connecting arm 401 on one side is fixedly installed with a power connection spring piece 502; the end of the rotary control column 404 is used to squeeze the power connection spring piece 502, and the power connection spring piece 502 elastically fits the detection fixing piece 501; the detection fixing piece 501, the squeezing power connection spring piece 502 and the indicator light 104 are connected in series with the power supply, and the interval fastening detection piece 4 can cooperate with the interval prompting part 5 to automatically detect the number of sleepers passing by, and the light source is used to prompt, which can ensure that the staff can tighten a fastener bolt after every three sleepers, and can perform interval fastening more accurately. Work, avoiding the traditional fastening method that needs to rely on manual counting. Once the counting is wrong, it will cause rework and other problems. The structure detection is accurate and direct, which can improve the accuracy of track fastening and reduce the error rate. At the same time, the prompt method is simple and intuitive. As the track fastener fastening specification, when the train is running, there will be a slight displacement between the rails and the sleepers due to load changes. Interval fastening reserves adjustment space for the system, allowing workers to gradually correct loose bolts in subsequent inspections, avoiding the overall structure from losing flexibility due to one-time locking, especially the elasticity difference between the materials of wooden sleepers or concrete sleepers. Interval tightening can avoid local compression and deformation of the sleeper due to over-tightening of the bolts on one side, ensuring that the load is evenly transferred to the roadbed. The track gauge and track levelness need to be adjusted synchronously when tightening the fasteners. Interval operation allows for measurement and correction of deviations section by section to avoid difficulty in adjustment after one-time tightening. The slewing wheel 402 will be driven by friction to rotate ninety degrees each time it passes a sleeper. 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 slewing wheel 402 from idling. Because there are four positioning grooves 4021, that is, each time it passes four sleepers, the slewing control column 404 returns to the origin, so that the interval control indicator light 104 lights up for prompting.

[0030] like Figure 3 , Fig. 9 and Fig.10 As shown, the position-limiting centering portion 6 includes a position-limiting centering plate 601 fixedly installed at the bottom of the movable counterweight plate 101 by bolts; two L-shaped plates 602 are fixedly installed on the position-limiting centering plate 601; the two L-shaped plates 602 are symmetrically arranged; the position-limiting centering portion 6 also includes an obstacle switch 603 fixedly installed on the side of the position-limiting centering plate 601; an obstacle warning light 604 is fixedly installed on the position-limiting centering plate 601; the obstacle warning light 604 is electrically connected to the obstacle switch 603; a slide groove is provided on the front side of the position-limiting centering plate 601; the anti-deformation insurance portion 7 also includes a slide mounted on the The sliding block 701 is in the sliding groove on the front side of the limit center plate 601; the two sides of the sliding block 701 are inclined structures; two V-shaped spring pieces 702 are fixedly installed at the tail of the sliding block 701, and the ends of the two V-shaped spring pieces 702 are respectively connected to the inner sides of the two L-shaped plates 602; the sliding block 701 is aligned with the obstacle switch 603, and the use of the limit center part 6 can facilitate the staff to perform auxiliary positioning and correction work on the track, improve the track position accuracy, reduce the small amount of local deviation of the track, and at the same time improve the centering degree of the track fasteners on both sides to ensure the track safety. The installation is stable, and the anti-deformation insurance part 7 can be used to assist in testing obstacles before the fastener bolts to be tightened, so as to prevent the drag reduction roller that has not been removed or missed to be removed on the front side from affecting the tightening of the bolts. Because the drag reduction roller needs to support the track, its height is higher than the support height of the track fastener. If the fastener bolts are directly tightened, the drag reduction roller will directly squeeze and deform to damage the track, causing economic losses and delays in construction. The structure is directly and reliably tested, and the staff can intuitively know that the limit centering plate 601 is always on the side of the fastener base on the same side, and the limit centering plate 601 is tested through the fastener base. The track is limited in position, and then cooperated with four annular grooves 1031 to limit the track. As the movable 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 limit center plate 601 moves, the front sliding block 701 should not be blocked 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, and will no longer fit the obstacle switch 603. The obstacle warning light 604 can light up to warn. On the contrary, if there is an obstacle between the two sleepers,

[0031] The working principle of the technical solution provided by the present invention is as follows: After the roller 103 is placed on the track, the annular groove 1031 is used to roll and fit the track respectively. The handheld frame 102 is held by hand to 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 sloped structure, which can drive the guide block 206 to move up under the pressure of the front side fastener bolt. At this time, the lifting column 201 will move up and lengthen the downward pressure spring 202. As the movable counterweight plate 101 continues to be pushed to move, when the hexagonal socket 302 moves to the fastener bolt, the hexagonal socket 302 will be directly inserted into the fastener bolt under the pull of the downward pressure spring 202. At this time, the staff will obviously feel the blockage when pushing the movable counterweight plate 101 to move. At the same time, when the hexagonal socket 302 is inserted into the fastener bolt, the fastener bolt will squeeze the micro switch 303 into place, and the control prompt light 204 will light up to indicate that it is in place. During the process, tighten the driving motor 301 to continuously drive the hexagon socket 302 to tighten the fastener bolt. When the mobile counterweight plate 101 moves, it can drive the rotating wheel 402 to move together. At this time, the rubber soft sleeve provided on the outside of the rotating wheel 402 will be rubbed by the sleepers and rotate. The rotating wheel 402 will be driven to rotate ninety degrees every time it passes a sleeper. 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. When the rotating wheel 402 rotates, it will drive the rotating control column 404 to rotate together. The rotating control column 404 can squeeze the power-connected spring piece 502 to elastically fit the detection fixing piece 501, so that the control indicator light 104 lights up for prompting. Because there are four positioning grooves 4021, that is, every time it passes four sleepers, the rotating control column 404 returns to the origin, so that the interval control indicator light 104 lights up for prompting;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. ;

[0032] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
