Description

Technical Field

[0001] The invention belongs to the field of ballastless track equipment, in particular to a ballastless track fine-tuning frame and a use method thereof. Background Art

[0002] Ballastless track is a track structure that uses an integral foundation such as concrete and asphalt mixture to replace the granular gravel roadbed. Ballastless track has the advantages of good smoothness, good stability, long service life and good durability. The track bearing platform is a directly cast reinforced concrete structure with rigid characteristics. The rails on the track bearing platform are directly connected to the bridge beam body through fasteners. Compared with the track plate, the track bearing platform can be approximately regarded as a mass block.

[0003] The ballastless track bearing platform fine-tuning frame is an auxiliary tool used to accurately adjust the position and posture of the bearing platform. During the ballastless track laying process, the position and posture accuracy of the bearing platform has an important impact on the smoothness of the track and the running stability of the train. The fine-tuning frame is required to ensure that the installation accuracy of the bearing platform meets the design requirements.

[0004] However, the above technologies often have the following defects: the currently used ballastless track fine-tuning frame generally requires the removal of the completed track fasteners, and then the fine-tuning frame is installed in the threaded holes of the fasteners before the track platform can be measured and fine-tuned. However, the removal of the track fasteners is very prone to deviations during the installation process, which in turn leads to increased errors and affects the construction progress.

[0005] To this end, the present invention provides a ballastless track fine-tuning frame and a use method thereof. Summary of the invention

At the same time, the gear will shift the shift block, so that the shift block slides in the empty slot in the direction away from the gear. The two clamping columns can be positioned to avoid shaking through the design of the bevel on the surface of the shift block. At this time, the measuring prism is installed on the surface of the prism seat, and the measuring device is used for measurement. When disassembly is required, the shift block is directly rotated in the direction away from the gear. The spring reset drives the clamping column to reset, so that the frame body can be removed.

[0016] Preferably, the air outlet and the air pipe are both provided with elastic membranes, and the surface of the elastic membranes are provided with elastic shrinkage holes; during operation, the air outlet and the elastic membranes in the air pipe can effectively prevent the entry of impurities and foreign objects, avoid blockage, and at the same time increase the pressure of the gas when it is ejected, further improving the cleaning effect.

[0017] A method for using a ballastless track fine-tuning frame, the method using the above-mentioned ballastless track fine-tuning frame, comprises the following steps: S1: Place the frame body on the rail support platform, press the frame body downward, clamp the two clamping columns on the rail support platform, and then turn the knob counterclockwise to reel in the connecting rope, position the two clamping columns, and then install the measuring prism on the surface of the prism seat and measure with the measuring device; S2: When the clamping column is installed to the extreme position of the rail support platform, the extrusion block will be forced to rotate and squeeze the cutter head, causing the cutter head to retract into the sliding cavity and shrink the blade in advance.

When the top plate moves upward, it drives the push plate to squeeze the elastic block 2 in the inner cavity, so that the gas in the elastic block 2 is blown to the anti-slip pad and both sides of the rail support platform through the air outlet.

[0018] S4: When the measuring object of the frame body needs to be modified, the electric telescopic rod in the lifting assembly lifts the frame body and makes the clamping column set on the frame body leave the track. Then the electric turntable turns and changes the position of the clamping column on the original basis. The base of the rail support platform is re-detected and the distance between the bases is detected through the clamping column.

[0020] 2. The present invention describes a ballastless track fine-tuning frame and a method of use. When the frame body is pressed downward, the rail support platform squeezes the top plate, causing the top plate to move upward, and at the same time stretches the spring to generate tension. When the top plate moves upward, it drives the push plate to squeeze the elastic block 2 in the inner cavity, so that the gas in the elastic block 2 is blown toward the anti-slip pad and both sides of the rail support platform through the air outlet, thereby improving the cleaning effect of the cutter head.

[0021] 3. Therefore, while the track support platform is being inspected using the frame body, the track position of the track support platform is inspected after the track is laid.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0026] Embodiment 1: Figures 1 to 7As shown, a ballastless track fine-tuning frame according to an embodiment of the present invention comprises a rail support platform 1 and a frame body 2. The frame body 2 is located above the rail support platform 1. A prism seat 4 is fixedly connected to the surface of the frame body 2. A group of slide grooves 9 are provided on the surface of the frame body 2. A clamping column 6 is slidably connected to the slide groove 9 through a spring. An anti-slip pad 7 is bonded to the surface of the clamping column 6. A cavity 15 is provided in the frame body 2. A reel 14 is rotatably connected to the cavity 15. One end of the reel 14 passes through the cavity 15 and is fixedly connected to a knob 5. A connecting rope 8 is fixedly connected to the surface of the reel 14. The other end of the connecting rope 8 is fixedly connected to the surface of the clamping column 6. An empty groove 10 is provided on the surface of the frame body 2. A shift block 3 is slidably connected to the empty groove 10. The shift block 3 is "L"-shaped. A spring sheet 11 is fixedly connected to one side of the shift block 3. The other end of the spring sheet 11 is a free end. A gear 13 is fixedly sleeved on the surface of the reel 14. An angle is provided on the short arm end of the shift block 3. During operation, the frame body 2 is placed on the rail support platform 1, and then the frame body 2 is pressed downward, the two clamping columns 6 are clamped on the rail support platform 1 respectively, and then the knob 5 is turned counterclockwise, so that the knob 5 drives the rotating shaft to rotate, and at the same time, the reel 14 will reel up the connecting rope 8, and at the same time, the two clamping columns 6 are driven to move towards each other through the reeling of the connecting rope 8, and at the same time, the spring will be squeezed to generate elastic force, and when the reel 14 rotates, the gear 13 will also be driven to rotate, and at the same time, the gear 13 will shift the shifting block 3, so that the shifting block 3 is in the empty slot 10, in the direction away from the gear 13 By sliding, the bevel design of the surface of the shift block 3 can prevent the gear 13 from rotating in the opposite direction, and the two clamping columns 6 can be positioned to avoid shaking. At this time, the measuring prism is installed on the surface of the prism seat 4, and the measurement is carried out in conjunction with the measuring device. When disassembly is required, the shift block 3 is directly shifted away from the gear 13, and the spring reset drives the clamping column 6 to reset, so that the frame body 2 can be removed. By cooperating with the clamping column 6 with the reel 14, the connecting rope 8 and the shift block 3, the rail fasteners that have been constructed do not need to be removed, and the rail support platform 1 can be measured and fine-tuned, which effectively reduces the error.

[0027] The clamping column 6 is provided with a sliding cavity 18, in which a scraper 20 is slidably connected via an elastic member. During operation, since the rail support platform 1 is generally installed outdoors, impurities such as sand and gravel are easily adhered to the surface. At this time, the scraper 20 can be used to clean the surface to avoid unbalanced clamping.

[0028] The scraper 20 is divided into a handle 24 and a cutter head 22, and the cutter head 22 is magnetically connected to the handle 24 via a magnetic block; during operation, the cutter head 22 and the handle 24 are magnetically mounted, so that the cutter head 22 can be quickly replaced.

[0029] The bottom end of the clamping column 6 is rotatably connected to an extrusion block 21 through a torsion spring. The extrusion block 21 is made of elastic material. A lever 31 is fixedly connected to the surface of the extrusion block 21, and a groove 32 is provided on the surface of the cutter head 22. During operation, when the clamping column 6 is installed to the extreme position of the rail support platform 1, the extrusion block 21 will be forced to rotate. At this time, the extrusion block 21 will squeeze the cutter head 22, causing the cutter head 22 to retract into the sliding cavity 18, shrinking the blade in advance to avoid damage to the blade when the two clamping columns 6 are clamped. The extrusion block 21 made of elastic material can squeeze the rail support platform 1 after the frame body 2 is installed in place, thereby further improving the clamping effect of the clamping column 6.

[0030] The end of the knife handle 24 away from the knife head 22 is fixedly connected to the slide bar 23, and the other end of the slide bar 23 passes through the slide cavity 18 and is fixedly connected to the limit block 26. A groove 25 is provided on the surface of the clamping column 6, and the limit block 26 is located in the groove 25. A limit groove 29 is provided on the surface of the knife handle 24, and a clamping block 28 is slidably connected to the side wall of the slide cavity 18 through a spring, and an arc angle is provided on the surface of the clamping block 28; when working, after the knife head 22 is retracted into the slide cavity 18, the clamping block 28 will be driven by the spring to be stuck in the limit groove 29 to limit the knife head 22. At this time, when the clamping column 6 is removed, the knife head 22 will not rub against the support rail platform 1, thereby improving the service life of the knife head 22. At the same time, after the knife head 22 is retracted, it is prevented from scratching the staff. When it is needed, the limit block 26 is pressed so that the limit block 26 drives the slide bar 23 to push the knife head 22 out.

[0031] An elastic rope 27 is fixedly connected to the surface of the clamping block 28, and the other end of the elastic rope 27 is fixedly connected to the extrusion block 21. A limiting groove 230 is provided on the surface of the knife handle 24, and the depth of the limiting groove 230 is greater than the limiting groove 1 29. During operation, after the cutter head 22 is pushed out, the clamping block 28 will be stuck in the limiting groove 230 for fixed limiting, so as to prevent the cutter head 22 from shaking back and forth when the clamping column 6 is stuck on the surface of the rail support platform 1. When the extrusion block 21 rotates, the elastic rope 27 is stretched, so that the elastic rope 27 drives the clamping block 28 to disengage from the limiting groove 230.

[0032] The elastic member is an elastic block 17, which is hollow, and is fixedly connected to the handle 24. A plurality of air pipes 19 are connected to the surface of the elastic block 17, and the other end of the air pipe 19 is in an open state and is located on the surface of the cutter head 22. When working, when the cutter head 22 retracts into the sliding cavity 18, the handle 24 is driven to squeeze the elastic block 17, so that the gas in the elastic block 17 is blown toward the cutter head 22 through the air pipe 19, and the impurities adhering to the surface of the cutter head 22 are cleaned. The surface of the clamping column 6 is fixedly connected to a cross bar 33, and the surface of the cross bar 33 is fixedly connected to a connecting plate 34. The connecting plate 34 The other end is fixedly connected with a top plate 35, which is in an arc shape. An inner cavity 38 is opened in the clamping column 6. The cross bar 33 is in a "U" shape, and the two short arm ends of the sliding rod 23 pass through the inner cavity 38, and are slidably connected in the inner cavity 38 by a spring; during operation, when the frame body 2 is installed on the surface of the support rail platform 1, the frame body 2 can be longitudinally centered by the top plate 35, so as to further improve the measurement efficiency. When the frame body 2 is pressed downward, the support rail platform 1 squeezes the top plate 35, so that the top plate 35 moves upward, and at the same time, the spring is stretched to generate tension. When the frame body 2 is removed, the top plate 35 is reset.

[0033] An elastic block 2 40 is fixedly connected in the inner cavity 38, and a push plate 37 is slidably connected in the inner cavity 38. The short arm end surface of the cross bar 33 is fixedly connected to the push plate 37. The elastic block 2 40 is hollow, and a plurality of air outlet holes 39 are opened on the surface of the clamping column 6, and the air outlet holes 39 are connected with the elastic block 2 40. When working, when the top plate 35 moves upward, it will drive the push plate 37 to squeeze the elastic block 2 40 in the inner cavity 38. The gas is squeezed by the elastic block 2 40, and the gas is blown to the anti-slip pad 7 and both sides of the rail support platform 1 through the air outlet holes 39, thereby improving the cleaning effect of the cutter head 22.

[0034] The air outlet 39 and the air pipe 19 are both provided with elastic membranes, and the surfaces of the elastic membranes are provided with elastic shrinkage holes. During operation, the air outlet 39 and the elastic membranes in the air pipe 19 can effectively prevent the entry of foreign matters and impurities, thus avoiding blockage. At the same time, the pressure of the gas during ejection can be increased, further improving the cleaning effect.

When the position of the object detected by the clamping column 6 changes, the lifting component 46 rotates the support frame 202 of the specimen body 2, and the support frame 202 drives the position of the clamping column 6 on the mounting frame 210 to turn. Among them, the structure possessed by the rail support platform 1, when being placed, the placement of its own base and the track still needs to be detected multiple times to confirm whether the placement of the rail support platform 1 meets the construction standards, and during the placement During track construction, the construction itself will still have an impact on the position of the base of the track support platform 1, which will cause the position of the base to shift during the construction of the track. Therefore, while the track support platform 1 is being inspected using the frame body 2, the track position of the track support platform 1 is inspected after the track is laid. After the inspection is completed, without changing the placement of the frame body 2, the lifting component 46 is used to turn, and the clamping column 6 is separated from the track of the track support platform 2, and the position between the two groups of clamping columns 6 is extended by the adjustment component 43, and the base of the track support platform 1 is inspected. After the inspection is completed, it can be reset and the track of the track support platform 1 can be re-inspected. At this time, the position of the frame body 2 will not change, so as to avoid affecting the accuracy of the construction and reduce the number of times the frame body structure is re-erected.

[0036] The adjusting assembly 43 includes an adjusting chamber 4301, an adjusting plate 44 and a connecting contact head 45, and the adjusting chamber 4301 is connected to the adjusting plate 44 at one side away from the mounting frame 201, and the connecting contact head 45 is installed at the edge of the adjusting plate 44, and the adjusting chamber 4301 and the adjusting plate 44 form a sliding connection structure through a slide groove, and the lifting assembly 46 includes an electric turntable 47, a connecting collar 48 and an electric telescopic rod 49, and the connecting collar 48 is installed below the electric turntable 47, and the electric telescopic rod 49 is installed below the connecting collar 48. 9, wherein the adjusting plate 44 in the adjusting assembly 43 is driven by an internal motor, and the output shaft of the motor is meshed with the teeth of the adjusting plate 44 through the gear, and drives the adjusting plate 44 to move, and the mounting frame 201 and the supporting frame 202 provided at one end of the clamping column 6 to be extended are in a snap-fitting structure, so that when extending, the clamping column is not affected by the supporting frame 202, and the height of the frame body 2 can be lifted by the electric telescopic rod 49, and the position of the clamping column 6 of the frame body 2 can be changed by the electric rotating disk 47.

[0037] like Fig.10As shown, a method for using a ballastless track fine-tuning frame, the method adopts the above-mentioned ballastless track fine-tuning frame, and includes the following steps: S1: Place the frame body 2 on the rail support platform 1, press the frame body 2 downward, clamp the two clamping columns 6 on the rail support platform 1 respectively, and then turn the knob 5 counterclockwise to reel the connecting rope 8, position the two clamping columns 6, and then install the measuring prism on the surface of the prism seat 4, and measure with the measuring device; S2: When the clamping column 6 is installed to the extreme position of the rail support platform 1, the squeezing block 21 will be forced to rotate and squeeze the cutter head 22, so that the cutter head 22 is retracted into the sliding cavity 18, and the blade is retracted in advance. At the same time, the squeezing block 21 made of elastic material will be stuck in the gap between the rail support platform 1 and the clamping column 6, and generate expansion force to continuously squeeze the rail support platform 1; S3: When the frame body 2 is pressed downward, the rail support platform 1 squeezes the top sheet 35, causing the top sheet 35 to move upward, and at the same time, the spring is stretched to generate tension. When the top sheet 35 moves upward, the push plate 37 is driven to squeeze the elastic block 2 40 in the inner cavity 38, so that the gas in the elastic block 2 40 is blown toward the anti-slip pad 7 and both sides of the rail support platform 1 through the air outlet 39; S4: When the measuring object of the frame body 2 needs to be modified, the electric telescopic rod 49 in the lifting assembly 46 lifts the frame body 2 and makes the clamping column 6 set on the frame body 2 leave the track. Then the electric turntable 47 turns and changes the position of the clamping column 6 on the original basis. The base of the rail support platform 1 is re-detected and the distance between the bases is detected through the clamping column 6.

[0038] Working principle: Place the frame body 2 on the rail support platform 1, then press the frame body 2 downward, clamp the two clamping columns 6 on the rail support platform 1 respectively, and then turn the knob 5 counterclockwise to make the knob 5 drive the rotating shaft to rotate, and at the same time the reel 14 will reel up the connecting rope 8, and at the same time the reeling of the connecting rope 8 will drive the two clamping columns 6 to move towards each other, and at the same time the spring will be squeezed to generate elastic force, and when the reel 14 rotates, the gear 13 will also be driven to rotate, and at the same time the gear 13 will shift the shifting block 3, so that the shifting block 3 is in the empty slot 10 and moves away from the gear 13, the two clamping columns 6 can be positioned by the design of the bevel on the surface of the shift block 3 to avoid shaking. At this time, the measuring prism is installed on the surface of the prism seat 4, and the measurement is carried out in conjunction with the measuring device. When disassembly is required, the shift block 3 is directly rotated in the direction away from the gear 13, and the spring reset drives the clamping column 6 to reset, so that the frame body 2 can be removed. The clamping column 6 cooperates with the reel 14, the connecting rope 8 and the shift block 3 to avoid removing the completed track fasteners, so that the rail support platform 1 can be measured and fine-tuned, which effectively reduces the error; Since the rail support platform 1 is generally installed outdoors, impurities such as sand and gravel are easily adhered to the surface. At this time, the scraper 20 can be used to clean the surface to avoid the situation of unbalanced clamping. The cutter head 22 and the handle 24 installed by magnetic attraction can quickly replace the cutter head 22. When the clamping column 6 is installed to the extreme position of the rail support platform 1, the squeeze block 21 will be forced to rotate. At this time, the squeeze block 21 will squeeze the cutter head 22, so that the cutter head 22 is retracted into the sliding cavity 18, and the blade is retracted in advance to avoid damage to the blade when the two clamping columns 6 are clamped. The squeeze block 21 made of elastic material can squeeze the rail support platform 1 after the frame body 2 is installed in place, thereby further improving the clamping effect of the clamping column 6. After the cutter head 22 is retracted into the slide cavity 18, the clamping block 28 will be driven by the spring to fit into the limit groove 29 to limit the cutter head 22. At this time, when the clamping column 6 is removed, the cutter head 22 will not rub against the support rail platform 1, thereby increasing the service life of the cutter head 22. At the same time, after the cutter head 22 is retracted, it is prevented from scratching the staff. When it is needed, the limit block 26 is pressed so that the limit block 26 drives the slide rod 23 to push the cutter head 22 out. After the cutter head 22 is pushed out, the clamping block 28 is pressed into the limit groove 29 to limit the cutter head 22. 8 will be stuck in the limiting groove 2 30 for fixed limiting, so as to prevent the cutter head 22 from shaking back and forth when the clamping column 6 is stuck on the surface of the rail support platform 1. When the squeezing block 21 rotates, the elastic rope 27 is stretched, so that the elastic rope 27 drives the clamping block 28 to leave the limiting groove 2 30. When the cutter head 22 retracts into the sliding cavity 18, the knife handle 24 is driven to squeeze the elastic block 17, so that the gas in the elastic block 17 is blown to the cutter head 22 through the air pipe 19, and the impurities adhering to the surface of the cutter head 22 are cleaned; When the frame body 2 is installed on the surface of the rail support platform 1, the frame body 2 can be longitudinally centered by the top plate 35, so as to further improve the measurement efficiency. When the frame body 2 is pressed downward, the rail support platform 1 squeezes the top plate 35, so that the top plate 35 moves upward, and at the same time, the spring is stretched to generate tension. When the frame body 2 is removed, the top plate 35 is reset. When the top plate 35 moves upward, it drives the push plate 37 to squeeze the elastic block 2 40 in the inner cavity 38. The gas is squeezed by the elastic block 2 40 and blows toward the anti-slip pad 7 and both sides of the rail support platform 1 through the air outlet 39, so as to improve the cleaning effect of the cutter head 22.
