Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and particularly to a post-welding leveling device for turnout tie plates. Background Art

[0002] At present, the post-welding leveling of turnout tie plates relies on manual operation of ordinary presses, and manual operation of a straight-edge is used for the flatness detection of turnout tie plates. The detection accuracy is low, and the labor intensity of workers is high, which severely restricts the implementation and operation of automatic devices for turnout tie plates.

[0003] Currently, the post-welding leveling of turnout tie plates relies on traditional leveling devices, and most traditional leveling devices adopt simple mechanical structures, such as ordinary jacks combined with manual measurement. This method is greatly affected by human factors, and manual measurement errors are inevitable. At the same time, due to differences in the execution of the welding process in some parts, or additional stress acting on the local area of the tie plate, sometimes the deformation of the turnout tie plate is not evenly distributed, and there may be only large protrusions or depressions in local areas. This easily causes changes in the contact force between the wheels and the track when the train passes, resulting in vibrations and impacts, affecting the running stability and safety of the train. Moreover, local deformations require frequent detection and repair, but the lifting accuracy of the jack is limited and it is impossible to precisely control the tiny adjustment amount of local changes in the tie plate, increasing the workload and difficulty of track maintenance. The existing leveling devices are difficult to comprehensively and accurately handle these deformations. Therefore, a post-welding leveling device for turnout tie plates needs to be proposed. Summary of the Invention

[0014] Preferably, an electric lifting guide rod is installed on the top of the side side plate. A side abutment frame is installed on the top of the electric lifting guide rod. A plurality of support legs are magnetically connected to the bottom of the knuckle frame and the side side plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the present invention, with the cooperation of the leveling control component, in the positioning link, through the cooperation of the first and second servo guide rails in the azimuth adjustment component, precise positioning in the two-dimensional plane is achieved, and any local deformation area of the turnout tie plate can be quickly reached, greatly improving the pertinence and efficiency of the leveling operation, overcoming the drawback of difficult positioning of traditional devices. Under the action of structures such as the screw member, sliding point block, swing rod, and stress rod, the screw member rotates, driving the sliding point block to move up and down along the spiral groove, thereby causing the swing rod to swing. Through the synchronous rod, the stress rod generates a horizontal displacement, which is finally converted into the horizontal movement of the bearing abutting rod, so as to realize the leveling operation of the tie plate. This structure can flexibly and accurately control the direction and magnitude of the force on the tie plate, and can effectively cope with the complex local deformation of the turnout tie plate, greatly improving the leveling accuracy. In addition, the leveling control component is equipped with an electric telescopic rod and an energy absorber. The electric telescopic rod can flexibly adjust the extended or retracted length according to the actual leveling requirements, and finely adjust the force of the positioning leveling block on the tie plate. The energy absorber absorbs the possible impact force during leveling to prevent the tie plate from suffering secondary damage. The two cooperate to achieve dynamic fine adjustment and protection, comprehensively improving the leveling quality.

[0016] 2. In the present invention, with the cooperation of the azimuth adjustment component, when it is detected that the turnout tie plate is uneven and needs to be leveled, after installing the device on the top of the external movable vehicle through the mounting frame, the azimuth adjustment component is turned on. The first servo guide rail drives the second servo guide rail to slide. Under the intelligent autonomous analysis and judgment of the operator or the external PLC controller, according to the feedback of the laser detection sensor, the sliding of the two is precisely controlled, and the leveling block can be quickly moved approximately above the deformed area of the tie plate. This process greatly improves the positioning efficiency, overcomes the problem of difficultly quickly finding the deformed area, saves a lot of time for the subsequent leveling operation, and the azimuth adjustment component can flexibly adjust the angle. During the process of moving the leveling block, the circumferential rotation motor box cooperates to adjust the angle of the second shaft joint torque joint to ensure that the leveling block can better align with the deformed part of the tie plate. No matter how tricky the deformed position of the tie plate is, precise adaptation can be achieved, improving the pertinence and success rate of leveling. At the same time, through its coordinated work with other components, when the azimuth adjustment component drives the second servo guide rail to move, the belt drive structure is synchronously moved, facilitating the subsequent orderly operation of components such as the temperature control adjustment component, the electric telescopic abutment, and the leveling control component. Each component closely cooperates, significantly improving the flexibility and efficiency of the overall leveling operation, and comprehensively ensuring the efficient and precise completion of the turnout tie plate leveling work.

Specific implementation mode

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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 the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Example 1: Refer to Figure 1 - Figure 9 As shown in the figure: A turnout tie plate post-welding leveling device includes an azimuth adjustment component 100. The azimuth adjustment components 100 are symmetrically arranged. Inside each of the symmetrically arranged azimuth adjustment components 100, a fixed-point adjustment component 200 is slidably connected. The azimuth adjustment component 100 has a first servo guide rail 101. Inside the first servo guide rail 101, a second servo guide rail 102 is slidably connected. The fixed-point adjustment component 200 has a synchronous sliding seat 201. The synchronous sliding seat 201 is used to be installed at the bottom of the second servo guide rail 102 and slide synchronously with the first servo guide rail 101. At the side end of the bottom of the sliding block, a leveling control component 300 is installed. The leveling control component 300 includes a screw member 303, a sliding point block 308, and a swing rod 309. The sliding point block 308 is slidably connected to the outer spiral groove of the screw member 303. The top of the swing rod 309 is fixedly connected to the sliding point block 308. The bottom center end of the swing rod 309 is connected with a force-bearing rod 310 through a synchronous rod. The side end of the force-bearing rod 310 is connected with a knuckle 312. The side end of the knuckle 312 is connected with a bearing resistance rod 314. A positioning leveling block 315 is arranged on the top of the bearing resistance rod 314 for positioning the local change of the leveling cushion plate.

[0021] A key shaft column 304 is connected to the side end of the screw member 303. Both sides of the key shaft column 304 are key-connected with a control unit. A spiral guide member 302 is arranged inside each control unit. And a group of spiral guide members 302 is arranged on the right side of the screw member 303. An energy-saving drive servo motor 301 is arranged on the surface of the right control unit.

[0022] A guide slide rail 316 is arranged inside each control unit. A connecting guide slider 305 is slidably connected to the inner guide groove of the spiral guide member 302. The connecting guide slider 305 is slidably connected inside the guide slide rail 316 through two sliding saddles. Electric telescopic rods 306 are arranged on the tops of the two sliding saddles. An energy absorber 307 is arranged on the top of the electric telescopic rods 306.

[0023] The bottom of the bearing resistance rod 314 is connected with a stroke slider 313. The side end of the stroke slider 313 is slidably connected with a stroke guide rail 311. The side end of the stroke guide rail 311 is fixedly connected with a bearing frame. A circumferential rotation motor box 204 is arranged at the bottom of the bearing frame.

[0024] In this embodiment, first, before the post-welding leveling operation of the switch tie plate, the leveling device needs to be transported to the operation site and installed at a suitable position near the switch tie plate. The azimuth adjustment assembly 100 is symmetrically arranged. By adjusting its position, the entire device is aligned with the switch tie plate area to be leveled. When it is determined that there are local protrusions or depressions on the switch tie plate that need to be leveled, the azimuth adjustment assembly 100 is activated, causing the first servo guide rail 101 to start working to drive the second servo guide rail 102 to slide along its internal track, thereby driving the synchronous slide block 201 and the leveling control assembly 300 installed at the bottom side end of the synchronous slide block 201 to move. In this way, the leveling control assembly 300 is accurately positioned above the deformed area of the tie plate. For example, if it is detected through preliminary inspection that there is a depression at a certain corner of the switch tie plate, the first servo guide rail 101 and the second servo guide rail 102 are controlled to slide, and the leveling control assembly 300 is moved directly above the corner depression. When the leveling control assembly 300 reaches the designated position, the energy-saving drive servo motor 301 is started. The energy-saving drive servo motor 301 drives the key shaft column 304 to rotate. Since the key shaft column 304 is connected to the spiral member 303, the spiral member 303 rotates accordingly. The spiral groove outside the spiral member 303 cooperates with the sliding point block 308. As the spiral member 303 rotates, the sliding point block 308 moves up and down along the spiral track in the spiral groove. The up and down movement of the sliding point block 308 drives the swing rod 309 connected to it firmly, causing the center end at the bottom of the swing rod 309 to be connected to the stress rod 310 through the synchronous rod. The swing of the swing rod 309 causes the stress rod 310 to generate a horizontal displacement. The side end of the stress rod 310 is connected to the bearing resistance rod 314 through the knuckle 312. The horizontal displacement of the stress rod 310 is converted into the up and down horizontal movement of the bearing resistance rod 314. Then, a positioning leveling block 315 is installed at the top of the bearing resistance rod 314. When the bearing resistance rod 314 moves horizontally, when the positioning leveling block 315 contacts the deformed part of the switch tie plate, if it is a depressed area of the tie plate, the positioning leveling block 315 is pushed by the bearing resistance rod 314 to jack up the tie plate. If it is a protruding area of the tie plate, the positioning leveling block 315, with the assistance of the electric telescopic rod 306 and the energy absorber 307, applies a downward pressure to the tie plate in cooperation with the overall structure of the device to make the tie plate flat. At the same time, the stroke slider 313 connected to the bottom of the bearing resistance rod 314 slides in the stroke guide rail 311, guiding and stabilizing the movement of the bearing resistance rod 314. During the leveling process, fine adjustment is performed through the electric telescopic rod 306 and the energy absorber 307, enabling the electric telescopic rod 306 to adjust the length of its extension or retraction according to the actual leveling requirements, thereby finely adjusting the acting force of the positioning leveling block 315 on the tie plate. The energy absorber 307 absorbs the possible impact forces on both sides of the changed area of the tie plate during the leveling process, avoiding secondary damage to the tie plate. At the same time, pressure sensors are installed on the leveling control assembly 300 and the switch tie plate to monitor the pressure and displacement data during the leveling process in real time.And feedback these data to the external PLC controller, so that the external PLC controller can judge whether it is necessary to further adjust parameters such as the rotation speed of the energy-saving drive servo motor 301 and the telescopic amount of the electric telescopic rod 306 according to the preset flatness standard, and realize the dynamic adjustment of the leveling process. If the pressure is too high, the control system will reduce the rotation speed of the energy-saving drive servo motor 301 and decrease the rotation speed of the spiral part 303, thereby reducing the pressure of the positioning leveling block 315 on the backing plate. If the displacement does not reach the expectation, the control system will appropriately increase the extended length of the electric telescopic rod 306 and increase the acting force on the backing plate. When the leveling of a certain area is completed, operate the energy-saving drive servo motor 301 in reverse to make the spiral part 303 reverse, drive components such as the sliding point block 308, the swing rod 309, the force-bearing rod 310, and the bearing and resisting rod 314 to reset. Then, move the leveling control component 300 to the next area to be leveled through the orientation adjustment component 100, and repeat the above leveling steps until the local deformation areas of the entire turnout backing plate are all adjusted. Through the cooperation of the first servo guide rail 101 and the second servo guide rail 102 in the orientation adjustment component 100, the overall device can achieve precise positioning of the leveling control component 300 in the two-dimensional plane, quickly and accurately reach any local deformation area of the turnout backing plate, greatly improving the pertinence and efficiency of the leveling operation, solving the problem that the traditional device is difficult to quickly locate the local deformation area. Moreover, the leveling control component 300 adopts a transmission structure composed of a spiral part 303, a sliding point block 308, a swing rod 309, a force-bearing rod 310, etc., converting the rotation of the spiral part 303 into the horizontal movement of the bearing and resisting rod 314, thereby realizing the leveling of the backing plate, being able to more flexibly and precisely control the direction and magnitude of the acting force on the backing plate, improving the leveling accuracy, effectively coping with the complex local deformation conditions of the turnout backing plate. At the same time, by using the equipped electric telescopic rod 306 and the energy absorber 307, dynamic fine-tuning can be carried out according to the actual situation during the leveling process, and the impact force can be absorbed to protect the backing plate from damage.,

[0025] Embodiment 2: According to Figure 6 As shown, a first shaft joint torque joint 202 is installed at the side end of the synchronous sliding seat 201, and a second shaft joint torque joint 203 is rotatably connected to the side end of the first shaft joint torque joint 202.

[0026] The circumferential rotation motor box 204 is installed inside the side rod body of the second shaft joint torque joint 203, and an electric telescopic abutment 400 is installed at the bottom of the side rod body of the second shaft joint torque joint 203.

[0027] In this embodiment, when the above-mentioned operation of leveling the backing plate is carried out, the azimuth adjustment component 100 is started, so that the first servo guide rail 101 drives the second servo guide rail 102 to slide along its internal track, thereby driving the synchronous slide 201 to move. The movement of the synchronous slide 201 will cause the connected first knuckle torque joint 202 and the second knuckle torque joint 203 to move accordingly. By controlling the sliding direction and distance of the first servo guide rail 101 and the second servo guide rail 102, the leveling control component 300 is roughly moved above the deformed area of the backing plate. At the same time, the circumferential rotation motor box 204 starts to work. According to the position and angle requirements of the deformed area of the backing plate, it drives the second knuckle torque joint 203 to rotate, adjusts the angles of the electric telescopic abutment 400 and the leveling control component 300, so that it can better align with the deformed part of the backing plate. Then, when the leveling control component 300 approaches the deformed area of the backing plate, the electric telescopic abutment 400 is started, so that it extends and contacts the ground or the supporting structure around the backing plate, providing stable support for the whole device. At this time, the whole device can realize the precise position adjustment of the leveling control component 300 in the three-dimensional space through the fine adjustment of the first knuckle torque joint 202 and the second knuckle torque joint 203. The first knuckle torque joint 202 and the second knuckle torque joint 203 can flexibly change the angle according to the specific situation of the deformation of the backing plate, so that the positioning leveling block 315 can accurately fit the deformed part of the backing plate, preparing for the subsequent leveling operation. When the leveling of the backing plate reaches the preset standard, the energy-saving drive servo motor 301 is operated in reverse, so that the screw part 303 rotates in reverse, driving each component to reset, retracting the electric telescopic abutment 400, releasing the support state of the device, and then moving the leveling control component 300 to the initial position through the azimuth adjustment component 100, so as to level the next possible deformed area or end the operation. The whole device can adapt to the deformation of turnout backing plates with various complex shapes and positions, improving the accuracy and applicability of leveling, effectively coping with the inclination or special angles of the deformed parts of the backing plate, and enabling the electric telescopic abutment 400 to be adjusted in terms of extension and retraction according to the actual operation environment and the situation of the backing plate, adapting to different support heights and ground conditions.

[0028] Embodiment 3: According to Figure 4 and Figure 5 As shown, a belt drive structure 103 is installed on the surface of the side end frame of the second servo guide rail 102. The output end of the belt drive structure 103 is connected with a rotating pulley 104. A temperature control adjusting part 107 is installed on the surface of the rotating pulley 104. A high-efficiency heat conduction plate 106 is slidably connected to the top of the temperature control adjusting part 107. A laser detection sensor is installed at the side end of the high-efficiency heat conduction plate 106. A leveling block 105 is installed on the top of the high-efficiency heat conduction plate 106.

[0029] A mounting bracket 600 is fixedly connected to the side end of the first servo guide rail 101, and the mounting bracket 600 is used to be mounted on the top of an externally connected movable vehicle.

[0030] In this embodiment, when it is detected that the turnout tie plate is locally or integrally uneven after welding, affecting the driving safety and stability of the train, the device is firmly mounted on the top of the externally connected movable vehicle through the mounting bracket 600 to ensure the stability of the device during operation. Then, the azimuth adjustment assembly 100 is turned on, and the first servo guide rail 101 starts to work, driving the second servo guide rail 102 to slide along its track, so that the belt drive structure 103 at the side end of the second servo guide rail 102 also moves accordingly. Then, under the intelligent autonomous analysis and judgment of the operator or the externally connected PLC controller, it is possible to move the leveling block 105 approximately above the tie plate area to be leveled according to the actual deformation position of the turnout tie plate under the detection feedback of the laser detection sensor. During this process, the circumferential rotation motor box 204 can cooperate to adjust the angle of the second shaft torque joint 203 to make the leveling block 105 better align with the deformed part of the tie plate. After the leveling block 105 reaches the predetermined position, the belt drive structure 103 is started, and its output end drives the rotating pulley 104 to rotate. The temperature control adjustment part 107 on the surface of the rotating pulley 104 starts to work, and according to factors such as the material of the tie plate, the degree of deformation, and the ambient temperature, the temperature is precisely adjusted. The temperature control adjustment part 107 can adopt heating or cooling methods, and transfer the temperature to the leveling block 105 through the high-efficiency conduction plate 106 (where the leveling block 105 is made of shape memory alloy material). For some tie plates deformed due to internal stress generated by welding, appropriately increasing the temperature of the leveling block 105 can cause the leveling block 105 to deform to fit the shape of the deformed tie plate, making the overall leveling easier. When the temperature of the leveling block 105 reaches the appropriate value, the height and angle of the device are further adjusted through the electric telescopic support seat 400 to make the leveling block 105 closely fit the deformed part of the tie plate. At this time, the above-mentioned leveling control assembly 300 also starts to work, and the contact force detection sensors installed on the side of the leveling block 105 and the positioning leveling block 315 monitor the force exerted by the leveling block 105 and the positioning leveling block 315 on the tie plate in real time. If the pressure is insufficient, the control system will increase the power of the energy-saving drive servo motor 301 or adjust the running speed of the belt drive structure 103, so that the overall device can better adapt to different shapes and deformation conditions of the tie plate, improving the leveling accuracy and efficiency, and greatly improving the flexibility and efficiency of the operation.

[0031] Example 4: According to Figure 1 and Figure 2As shown, a side leveling assembly 500 is installed on the side of the mounting bracket 600. The side leveling assembly 500 includes a telescopic rod bracket 501. A knuckle bracket 502 is rotatably connected to the side end of the telescopic rod bracket 501. A side plate is connected to the side end of the knuckle bracket 502.

[0032] An electric lifting guide rod 503 is installed on the top of the side plate. A side abutment bracket 505 is installed on the top of the electric lifting guide rod 503. A plurality of support legs 504 are magnetically connected to the bottom of the knuckle bracket 502 and the side plate.

[0033] In this embodiment, when the above-mentioned external movable vehicle with the leveling device moves to a suitable position near the turnout tie plate to be leveled through the mounting bracket 600, and ensures the stability of the device, and when the azimuth adjustment assembly 100 and the leveling control assembly 300 are roughly moved above the main area where the tie plate needs to be leveled for preliminary positioning, the side leveling assembly 500 is started. The telescopic rod bracket 501 starts to extend, driving the knuckle bracket 502 to move towards the side of the tie plate. The knuckle bracket 502 rotates and adjusts the angle to make the side plate close to the side of the tie plate. Then, the support legs 504 are removed from the bottom of the knuckle bracket 502 and the side plate and placed in a suitable position to provide stable support for the side leveling assembly 500. During or after the above-mentioned main leveling operation, according to the deformation condition of the side of the tie plate, the electric lifting guide rod 503 of the side leveling assembly 500 is started, so that the electric lifting guide rod 503 rises or falls, driving the side abutment bracket 505 to press or lift the side of the tie plate to adjust the flatness of the side of the tie plate (where the shape and size of the side abutment bracket 505 can be designed according to the specific situation of the side of the tie plate to ensure that the side can be effectively leveled), so as to level the side of the tie plate as a whole, solve the problem that it is difficult to handle the side deformation, comprehensively improve the flatness of the entire turnout tie plate, improve the overall quality and safety of the railway turnout, and the overall device forms a multi-component collaborative operation with the azimuth adjustment assembly 100, the leveling control assembly 300, the belt drive and the temperature control adjustment structure, as well as the side leveling assembly 500, enabling the components to cooperate with each other to jointly complete the leveling task of the turnout tie plate, improving the leveling efficiency and quality.
