Description

Technical Field

[0001] The utility model belongs to the technical field of ballastless track slab fine-tuning construction, and in particular relates to a track slab fine-tuning sensor fixing frame. Background Art

[0002] The fine-tuning construction of ballastless track slabs is a high-precision installation and measurement work aimed at accurately adjusting the track slabs to the designed position. Before starting the fine-tuning, the track slabs need to be preliminarily rough-laid to ensure that they are roughly consistent with the designed position. The fine-tuning software is used to command the total station to observe the prisms placed at specific positions on the track slabs. The deviation between the measured value and the theoretical value is calculated based on the measured coordinate values, and then precise adjustments are made. After fine-tuning, a clamping device should be installed to fix the position of the track slab, and it should be clearly marked on the site to prevent accidental stepping on the fine-tuned track slab.

[0003] Problems with existing technologies:

[0004] During the fine-tuning construction of the track slab, the placement process of the sensors is mostly done by manually moving and placing the sensors one by one. The frequent reciprocating transportation will undoubtedly increase the construction time and seriously consume manpower. When using auxiliary devices to install the sensors, it is important to note how to install the sensors at the corresponding position on the board surface when the track slab is offset. This problem needs to be solved urgently. Utility Model Content

[0005] The utility model aims to provide a track plate fine-tuning sensor fixing frame, which can automatically complete the transportation and placement of the sensor, and can also automatically complete the placement of the sensor when the track plate has been offset.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A track plate fine adjustment sensor fixing frame, comprising a gantry moving frame, an inner frame, a track plate and a sensor, wherein a dual-axis servo motor is fixedly installed in the middle of both ends of the gantry moving frame, and the output shafts of the dual-axis servo motors are fixedly connected with screws, and the ends of the screws are screwed with pushing screw tubes, and both ends of the inner walls on both sides of the gantry moving frame are fixedly welded with inner wall guide rods, and the pushing screw tubes simultaneously form a sliding assembly relationship with the adjacent inner wall guide rods, and the ends of the inner wall guide rods are simultaneously slidably assembled with a wall-adhering adjustment frame, and the bottom end of the wall-adhering adjustment frame is fixedly installed with a guide wheel frame for fitting with the side wall of the track plate, and the side walls at the top of the wall-adhering adjustment frame are fixedly welded with push frames;

[0008] The inner walls on both sides of the gantry moving frame are equipped with climbing machines in a lifting sliding manner. There are two groups of climbing machines, and one group has two climbing machines. The inner walls of the climbing machines are fixedly welded with sliding frames, and the bottom ends of the inner walls of the climbing machines are fixedly installed with hydraulic cylinders.

[0009] A rotating frame is fixedly welded at the center above the inner frame, and an adapter frame is assembled above the inner frame through the rotation of the rotating frame, and push-bearing frames are fixedly welded on both sides of the outer wall of the rotating frame, and the ends of the four side branches of the adapter frame are slidably assembled inside the corresponding sliding frames, and push plates are slidably assembled on both sides of the adapter frame through slides that are integrally arranged under each branch end, and the push plates are placed on the outside of the corresponding push-bearing frames.

[0010] The ends of the four push frames are respectively placed outside the ends of the two push plates, and the two push frames located on different sides are used to push the push plates to press the corresponding push frames and rotate the inner frame when they are close to each other.

[0011] The ends of the telescopic output ends of the four hydraulic cylinders are aligned with the outer walls of the corresponding slides.

[0012] The central axis inside the inner frame is assembled with double-threaded screw rods 1 and 2 in a criss-cross rotation, and motor 1 and motor 2 are installed above the inner frame for driving the double-threaded screw rods 1 and 2 to rotate respectively.

[0013] Slide rods 1 are movably assembled on both sides of the inner frame, and slide rods 2 are movably assembled on both ends of the inner frame. The slide rods 1 and 2 are arranged at an angle, and a double tube body 3 is penetrated through the intersection point.

[0014] The two ends of the double-threaded screw rod 1 are threadedly connected to the double tube body 1, and the slide rod 1 movably penetrates the tube body located below the corresponding double tube body 1. The two ends of the double-threaded screw rod 2 are threadedly connected to the double tube body 2, and the slide rod 2 movably penetrates the tube body located above the corresponding double tube body 2.

[0015] The four double-tube bodies three are distributed at the four corners of the inner frame, and the bottoms of the double-tube bodies three are fixedly welded with connecting rods, and the bottom ends of the connecting rods are fixedly assembled with hook frames for temporarily hooking the sensors.

[0016] The technical effects achieved by the utility model are:

[0017] The utility model controls each guide wheel frame to fit into and contact with the outer wall of the track plate, so that the inner frame can deflect at the same offset angle of the track plate, and the rotating center frame will also move laterally during the process, eventually coinciding with the center axis of the track plate and the inner frame, ensuring that each sensor will be located at a corresponding detection position on the surface of the track plate. In the case where the track plate has been offset, the placement of the sensor can be automatically completed, and other mechanisms in the fixed frame can also complete the work of carrying the sensor from one track plate to the next, thereby completing the work of automatically lowering the sensor and saving the process of frequently installing the sensor.

[0027] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0028] like Figure 1-7 As shown, a track plate fine-tuning sensor fixing frame includes a gantry moving frame 1, an inner frame 2, a track plate 3 and a sensor 4, dual-axis servo motors 101 are fixedly installed in the middle of both ends of the gantry moving frame 1, and the output shafts of the dual-axis servo motors 101 are fixedly connected with screws 102, and the ends of the screws 102 are screwed with pushing screws 103, and the two ends of the inner walls on both sides of the gantry moving frame 1 are fixedly welded with inner wall guide rods 104, and the pushing screws 103 simultaneously form a sliding assembly relationship with the adjacent inner wall guide rods 104, and the ends of the inner wall guide rods 104 are simultaneously slidably assembled with wall-attached adjustment frames 105, and the bottom end of the wall-attached adjustment frame 105 is fixedly installed with a guide wheel frame 106 for fitting with the side wall of the track plate 3, and the side walls of the top of the wall-attached adjustment frame 105 are fixedly welded with push frames 107.

[0029] See attached Figure 3 The inner walls on both sides of the gantry moving frame 1 are assembled with climbing machines 108 in a lifting sliding manner. The climbing machines 108 are divided into two groups, and each group has two climbing machines. The inner walls of the climbing machines 108 are fixedly welded with sliding frames 109, and the bottom ends of the inner walls of the climbing machines 108 are fixedly installed with hydraulic cylinders 110.

[0030] See attached Figure 4A rotating frame 201 is fixedly welded at the center above the inner frame 2, and an adapter frame 202 is assembled on the top of the inner frame 2 through the rotating frame 201. Push frames 204 are fixedly welded on both sides of the outer wall of the rotating frame 201. The ends of the four side branches of the adapter frame 202 are slidably assembled inside the corresponding sliding frame 109. Push plates 203 are slidably assembled on both sides of the adapter frame 202 through slides 216 integrally arranged under each branch end, and the push plates 203 are placed on the outside of the corresponding push frames 204.

[0031] See attached Figure 1-Figure 4 The ends of the four push frames 107 are respectively placed on the outside of the ends of the two push plates 203, and the two push frames 107 located on different sides are used to push the push plates 203 to squeeze the corresponding push frames 204 and rotate the inner frame 2 when they approach each other. The ends of the telescopic output ends of the four hydraulic cylinders 110 are aligned with the outer walls of the corresponding slides 216.

[0032] According to the above structure, when the placement position of the track plate 3 is offset, Figure 7 As shown in the figure above, during the process of the gantry moving frame 1 moving to the top of the track plate 3, the guide wheel frame 106 comes into contact with the outer wall of the track plate 3. Due to the offset of the track plate 3, the two symmetrical wall-adhering adjustment frames 105 located on different inner walls will move away from each other. After the gantry moving frame 1 moves to the specified position, it stops. Then, the two dual-axis servo motors 101 will work and make the screw 102. The two pushing solenoids 103 on the same axis will move toward each other and push the corresponding wall-adhering adjustment frames 105 to start moving in turn. Then, the two wall-adhering adjustment frames 105 on the same axis will approach each other and finally cling to the side walls of the track plate 3 one after another.

[0033] Furthermore, in the process of the two sets of wall-adjusting frames 105 moving close to each other, the two push frames 107 on the same side will successively contact the two ends of a corresponding push plate 203 and deflect it. The inclination angle of the push plate 203 in the horizontal plane is the same as the inclination angle of the track plate 3 in the horizontal plane. Then the push plates 203 on both sides will squeeze the corresponding push-bearing frames 204 and finally deflect the inner frame 2. At this time, the inclination angle of the inner frame 2 in the horizontal plane is the same as the inclination angle of the track plate 3 in the horizontal plane. At the same time, when the inner frame 2 is deflected, the rotating core frame 201 will carry the inner frame 2 to move horizontally in the horizontal direction, and the branches of the inner frame 2 will telescope and slide in the corresponding sliding frames 109, so that the central axis L1 of the track plate 3 coincides with the central axis L2 of the inner frame 2. Figure 7 As shown in the figure below.

[0034] See attached Figure 4The central axis of the inner frame 2 is crisscrossed and rotated with double-threaded screw rods 1 205 and double-threaded screw rods 206, and a motor 1 207 and a motor 208 are installed on the upper part of the inner frame 2 for driving the double-threaded screw rods 1 205 and double-threaded screw rods 206 to rotate respectively. Slide rods 1 211 are movably assembled on both sides of the inner frame 2, and slide rods 212 are movably assembled at both ends of the inner frame 2. The slide rods 1 211 and the slide rods 212 are arranged at 90 degrees, and a double tube body 3 213 is arranged through the intersection point.

[0035] See attached Figure 4 and Figure 6 , both ends of the double-threaded screw 205 are screwed with a double-tube body 209, and a slide bar 211 movably penetrates the tube body located below the corresponding double-tube body 209, both ends of the double-threaded screw 206 are screwed with a double-tube body 210, and a slide bar 212 movably penetrates the tube body located above the corresponding double-tube body 210, four double-tube bodies 3 213 are distributed at the four corners of the inner frame 2, and the bottom of the double-tube body 3 213 is fixedly welded with a connecting rod 214, and the bottom end of the connecting rod 214 is fixedly assembled with a hook frame 215 for temporarily hooking the sensor 4.

[0036] According to the above structure, by controlling the motor 1 207 and the motor 2 208 to work, the two slide bars 1 211 and the two slide bars 212 are moved away from or close to each other, and then controlling the climbing machine 108, the sensor 4 is finally lowered into the corresponding pillow groove on the surface of the track plate 3, and then the motor 1 207 is controlled to make the two slide bars 1 211 move away from each other, and the hook frame 215 is separated from the sensor 4, and the sensor 4 completes the work of automatically lowering;

[0037] Through the above process, by controlling each guide wheel frame 106 to fit in contact with the outer wall of the track plate 3, the inner frame 2 can be deflected at the same offset angle of the track plate 3, and the rotating center frame 201 will also move laterally during the process, and finally the central axis of the track plate 3 and the inner frame 2 will coincide, ensuring that each sensor 4 will be located at the corresponding detection position on the surface of the track plate 3. Even if the track plate 3 has been offset, the placement of the sensor 4 can still be automatically completed, and other mechanisms in the fixed frame can also complete the work of carrying the sensor 4 from one track plate 3 to the next track plate 3, thereby completing the work of automatically lowering the sensor 4 and saving the process of frequently installing the sensor.

[0038] The working principle of the utility model is: when the placement position of the track plate 3 is offset, Figure 7As shown in the figure above, during the process of the gantry moving frame 1 moving to the top of the track plate 3, the guide wheel frame 106 comes into contact with the outer wall of the track plate 3. Due to the offset of the track plate 3, the two symmetrical wall-adhering adjustment frames 105 located on different inner walls will move away from each other. After the gantry moving frame 1 moves to the specified position, it stops. Then, the two dual-axis servo motors 101 will work and make the screw 102. The two pushing solenoids 103 on the same axis will move toward each other and push the corresponding wall-adhering adjustment frames 105 to start moving in turn. Then, the two wall-adhering adjustment frames 105 on the same axis will approach each other and finally cling to the side walls of the track plate 3 one after another.

[0039] In the process of the two sets of wall-adjusting frames 105 moving close to each other, the two push frames 107 on the same side will successively contact the two ends of a corresponding push plate 203 and deflect it. The inclination angle of the push plate 203 on the horizontal plane is the same as the inclination angle of the track plate 3 on the horizontal plane. Then the push plates 203 on both sides will squeeze the corresponding push-bearing frames 204 and finally deflect the inner frame 2. At this time, the inclination angle of the inner frame 2 on the horizontal plane is the same as the inclination angle of the track plate 3 on the horizontal plane. At the same time, when the inner frame 2 is deflected, the rotating core frame 201 will carry the inner frame 2 to move horizontally in the horizontal direction, and the branches of the inner frame 2 will telescope and slide in the corresponding sliding frames 109, so that the central axis L1 of the track plate 3 coincides with the central axis L2 of the inner frame 2. Figure 7 As shown in the figure below;

[0040] By controlling the motor 1 207 and the motor 2 208 to work, the two slide bars 1 211 and the two rods 212 move away from or approach each other, and then controlling the climbing machine 108, the sensor 4 will eventually be lowered into the corresponding pillow groove on the surface of the track plate 3, and then the motor 1 207 will be controlled to make the two slide bars 1 211 move away from each other, and the hook frame 215 will be separated from the sensor 4, and the sensor 4 will complete the work of automatically lowering;

[0041] Finally, each hydraulic cylinder 110 works and pushes the corresponding slide 216 to reset the rotating frame 201, and the dual-axis servo motor 101 works in reverse to reset the pushing solenoid 103.

[0042] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
