Description

Technical Field

[0001] The utility model relates to track beam measuring equipment, in particular to a guide rail beam guide surface spacing detection vehicle. Background Art

[0002] At present, one way to measure the distance between the guide surfaces of the guide beams of the guide rail type rubber wheel system is to use a handheld laser rangefinder. One end of the handheld laser rangefinder contacts the guide surface, sends a visible infrared laser toward the opposite guide surface, and reads the travel of the reflected laser to measure the guide surface. This method is a manual measurement with slow measurement speed and low efficiency. In addition, the staff will be easily fatigued when bending over for a long time.

[0003] Patent document CN 215766916 U discloses a track beam measuring vehicle, including a workbench, a support frame for setting the workbench horizontally, a superelevation measuring device for measuring the superelevation of the running surface of the track beam, an inner spacing measuring device for measuring the inner spacing of the guide surface of the track beam, and a plurality of running wheels; the superelevation measuring device is located on the workbench, the inner spacing measuring devices are in two groups, and are respectively installed on the support frame, and the running wheels are located below the workbench. During measurement, the running wheels are in contact with the running surface and can drive the measuring vehicle to move along the running surface. By integrating the superelevation measuring device and the inner spacing measuring device, the inner spacing and superelevation can be measured at the same time, without the need to replace the measuring tools or manual measurement, and the running wheels are rotated to drive the entire measuring vehicle to move on the track beam, so that the continuous measurement of the inner spacing and superelevation can be achieved, which improves the measurement efficiency while also improving the accuracy of the measurement data.

[0004] However, the inner spacing measuring device uses a laser distance measuring sensor or an infrared distance measuring sensor. If it encounters the guide beam joints and finger plate bolt holes during the measurement process, the light will pass through these areas, and the measurement results cannot be obtained, which is easy to produce abnormal measurement data.

[0069] like Figures 1 to 3As shown, the basic embodiment of the utility model provides a guide rail beam guide surface spacing detection vehicle, including a workbench 1, a plurality of universal running wheels 3, a guide wheel group and a first displacement detection device 5, a plurality of universal running wheels 3 are arranged on both sides of the workbench 1, and in a preferred case, the universal running wheels 3 are symmetrically arranged on both sides of the workbench 1, and the guide wheel group includes a first group of guide wheels and a second group of guide wheels, the first group of guide wheels is arranged on one side of the workbench 1, and the second group of guide wheels is arranged on the other side opposite to the workbench 1, as shown in FIG. Fig.11 As shown, the guide rail beam generally has two guide rail beam guide surfaces 10 arranged opposite to each other, the first group of guide wheels contacts one of the guide rail beam guide surfaces 10, the second group of guide wheels contacts the other guide rail beam guide surface 10, and the first group of guide wheels is configured to be able to move and maintain contact with the guide surfaces of the guide rail beam to adapt to the change in the spacing of the corresponding guide rail beam guide surfaces 10, the first displacement detection device 5 is used to detect the vertical displacement of the first group of guide wheels on the guide surface 10 of the guide rail beam, or the first displacement detection device 5 is used to detect the vertical displacement of the second group of guide wheels on the guide surface 10 of the guide rail beam, or the first displacement detection device 5 is used to detect the vertical displacement of the first group of guide wheels and the second group of guide wheels on the guide surface 10 of the guide rail beam.

[0070] It is understandable that one or more first displacement detection devices 5 may be provided. For example, two first displacement detection devices 5 may be provided on the workbench, wherein one first displacement detection device 5 is used to detect the vertical displacement of the first group of guide wheels on the guide surface 10 of the guide rail beam, and the other first displacement detection device 5 is used to detect the vertical displacement of the second group of guide wheels on the guide surface 10 of the guide rail beam. In this way, the sum of the displacements detected by the two first displacement detection devices 5 is the change in the spacing between the two guide surfaces 10 of the guide rail beam. Alternatively, multiple first displacement detection devices 5 may be provided to detect the vertical displacement of the first group of guide wheels on the guide surface 10 of the guide rail beam, and multiple first displacement detection devices 5 may be provided to detect the vertical displacement of the second group of guide wheels on the guide surface 10 of the guide rail beam. These simple variations of the technical solutions also fall within the scope of protection of the present utility model. The vertical displacement of the guide surface 10 of the guide rail beam refers to the displacement in the direction perpendicular to the guide surface 10 of the guide rail beam.

[0071] Based on the above technical solution, the first group of guide wheels and the second group of guide wheels are used to contact the two guide rail beam guide surfaces 10, which can avoid the influence of the guide rail beam joints, finger plate bolt holes, etc. on the measurement during the detection process, and the first group of guide wheels can move according to the change of the spacing of the corresponding guide rail beam guide surfaces 10, and use a contact detection method to detect the changes in the guide surfaces 10 of the guide rail beams, and use a first displacement detection device 5 to detect the displacement of the first group of guide wheels and / or the second group of guide wheels, and indirectly detect the changes in the spacing between the two guide rail beam guide surfaces 10, so that the detection data is more real and reliable.

[0072] In some embodiments, Figure 3 As shown, the first set of guide wheels includes a first guide wheel assembly 401, which is connected to the workbench 1 through a guide surface spacing displacement device 2. The guide surface spacing displacement device 2 is used to adjust the displacement of the first guide wheel assembly 401 along the direction of the vertical guide rail beam guide surface 10 to keep the first guide wheel assembly 401 in contact with the corresponding guide rail beam guide surface 10. Figure 3 In the embodiment, only one first guide wheel assembly 401 is provided at the bottom of the workbench 1, and a second guide wheel assembly 402 is provided on the same side thereof. Both the first guide wheel assembly 401 and the second guide wheel assembly 402 have the ability to adapt to the change in the spacing of the corresponding guide rail beam guide surface 10 and perform a certain degree of displacement. The technical solution of the utility model is not limited to Figure 3 The combination of a first guide wheel assembly 401 and a second guide wheel assembly 402 shown can be selected according to the design requirements in terms of the number and combination of the first guide wheel assembly 401 and the second guide wheel assembly 402. For example, two first guide wheel assemblies 401 or more first guide wheel assemblies 401 can be provided, and the first guide wheel assembly 401 is connected to the workbench 1 via a guide surface spacing displacement device 2; or, two second guide wheel assemblies 402 or more second guide wheel assemblies 402 can be provided; all of which fall within the protection scope of the present utility model.

[0073] In some embodiments, Figure 8As shown, the first guide wheel assembly 401 includes a first guide wheel 401a, a first guide wheel bracket 401b and a second displacement detection device 401d. The first guide wheel 401a and the second displacement detection device 401d are both mounted on the first end of the first guide wheel bracket 401b, and the first guide wheel 401a and the second displacement detection device 401d are coaxially arranged. The first guide wheel bracket 401b is preferably an L-shaped structure, so that the edge of the first guide wheel 401a can extend out of the edge of the workbench 1, and then can maintain contact with the corresponding guide rail beam guide surface 10. Of course, the first guide wheel bracket 401b is not limited to the L-shaped structure, and can also be other structures that can achieve similar functions. The first displacement detection device 5 can be arranged directly opposite to the first guide wheel bracket 401b, and indirectly detect the spacing change of the guide rail beam guide surface 10 by detecting the displacement of the first guide wheel bracket 401b, and convert the lateral contact displacement of the first guide wheel 401a into an optical non-contact measurement, and the measurement method is simple and accurate. The second end of the first guide wheel bracket 401b is detachably connected to the guide surface spacing displacement device 2, and is installed at the bottom of the workbench 1 through the guide surface spacing displacement device 2. The second displacement detection device 401d is used to detect the displacement information of the first guide wheel 401a along the direction parallel to the corresponding guide rail beam guide surface 10, so that it can be used in combination with the displacement of the first group of guide wheels detected by the first displacement detection device 5 to adapt to the spacing change of the corresponding guide rail beam guide surface 10, and can obtain information such as the position where the spacing change of the guide rail beam guide surface 10 occurs and the size of the spacing change, so as to facilitate the staff to accurately find the position where the deformation of the guide rail beam guide surface 10 occurs, and make corrections according to the size of the deformation. Among them, the first displacement detection device 5 can be a laser displacement sensor, an infrared displacement sensor, a wire displacement sensor, a displacement sensor and other types of displacement measurement sensors.

[0074] In some embodiments, Figure 8As shown, the second displacement detection device 401d can be a rotary incremental encoder. The second displacement detection device 401d is installed on the first end of the first guide wheel bracket 401b through the rotary incremental encoder fixing block 401e. The second displacement detection device 401d is coaxially connected to the first guide wheel 401a. The first guide wheel 401a moves along a direction parallel to the guide surface 10 of the guide rail beam. As the first guide wheel 401a moves, the second displacement detection device 401d feeds back the deformation position information to the data acquisition device 6 in real time, and the data acquisition device 6 feeds back the deformation position information to the computer 7; at the same time, the first displacement detection device 5 also detects the spacing change amount information of the guide surface 10 of the guide rail beam, and feeds it back to the data acquisition device 6, and the data acquisition device 6 feeds back the spacing change amount information to the computer 7. On the display screen of the computer 7, the relationship curve between the deformation position and the spacing change amount of the guide surface 10 of the guide rail beam can be displayed in real time, and the spacing change of the guide surface 10 of the guide rail beam can be displayed more intuitively. The data acquisition device 6 may be a dynamic data acquisition instrument, which is a conventional device for data acquisition and will not be described in detail.

[0075] In some embodiments, Figures 5 to 7 As shown, the guide surface spacing displacement device 2 includes a connecting seat 201, a displacement device main frame 203, a bracket locking device 207 and an elastic deformation mechanism 208. The connecting seat 201 is used to connect with the workbench 1. The displacement device main frame 203 is installed on the connecting seat 201 and can move vertically along the guide surface 10 of the guide rail beam. The bracket locking device 207 is installed on the displacement device main frame 203 and can move vertically along the guide surface 10 of the guide rail beam. The elastic deformation mechanism 208 is installed on the displacement device main frame 203, and the elastic deformation mechanism 208 is connected to the end of the bracket locking device 207. The second end of the first guide wheel bracket 401b is detachably connected to the bracket locking device 207.

[0076] like Figure 6 and Figure 7 As shown, the bracket locking device 207 includes a bracket locking mounting plate and a bracket locking groove, the bracket locking groove is installed at the bottom of the bracket locking mounting plate, and a slide groove is arranged on the top of the bracket locking mounting plate, which cooperates with the second linear guide rail 206 on the displacement device main frame 203, so that the bracket locking device 207 can slide relative to the displacement device main frame 203. Figure 7As shown, a buckle hook piece 209 is provided on the outer surface of the bracket locking groove, and a buckle 401c is provided on the second end of the first guide wheel bracket 401b. When the first guide wheel assembly 401 is installed on the bracket locking device 207, the end of the second end of the first guide wheel bracket 401b is inserted into the bracket locking groove, and a bolt can be used to pass through the side wall of the bracket locking groove to fasten the end of the second end of the first guide wheel bracket 401b. At the same time, the buckle 401c is buckled with the buckle hook piece 209, so that the first guide wheel assembly 401 is installed and fastened on the bracket locking device 207. It should be noted that the installation method between the first guide wheel assembly 401 and the bracket locking device 207 is not limited to the above-mentioned buckle method, and other methods, such as threaded connection, can also be used. The elastic deformation mechanism 208 includes a pair of bolts and a pair of springs. The springs are sleeved on the bolts. One end of the bolts is tightly connected to the main frame 203 of the displacement device, and the other end of the bolts passes through the baffle at the end of the bracket locking device 207. The spring and the baffle can be set to be in abutment with each other. In this way, the spring can be expanded and contracted with the movement of the bracket locking device 207 to ensure that the first guide wheel assembly 401 can always be in abutment with the corresponding guide surface 10 of the guide rail beam.

[0077] Generally, when the guide rail beam guide surface spacing detection vehicle is installed on the guide rail beam, it is necessary to adjust the position of the first guide wheel assembly 401 so that the first guide wheel assembly 401 abuts against the corresponding guide rail beam guide surface 10. Figure 5 and Figure 7 As shown, a slide groove is provided on the displacement device main frame 203, and the first linear guide rail 202 is installed on the connecting seat 201. Through the cooperation between the slide groove and the first linear guide rail 202, the displacement device main frame 203 can slide relative to the connecting seat 201, thereby driving the bracket locking device 207 to move. Figure 5 As shown, a screw mechanism 204 is provided on the main frame 203 of the displacement device. The screw mechanism 204 includes a slider, a mounting seat and a screw. The slider can be slidably mounted on the screw, and the end of the screw can be rotatably connected to the mounting seat. The screw mechanism 204 can be a hand-cranked screw mechanism 204. The screw mechanism 204 can be connected to the workbench 1 through its mounting seat. At the same time, the screw mechanism 204 can be connected to the main frame 203 of the displacement device through the slider. By shaking the screw mechanism 204, the main frame 203 of the displacement device can be driven. 3 moves relative to the workbench 1. Further, a screw locking member 205 can be provided on the mounting seat of the screw mechanism 204. The screw locking member 205 can be a bolt. By rotating the screw locking member 205, the state of the screw mechanism 204 can be restricted. Therefore, when the guide rail beam guide surface spacing detection vehicle is initially installed on the guide rail beam, the moving position of the displacement device main frame 203 relative to the workbench 1 can be adjusted, so as to make the first guide wheel assembly 401 abut against the corresponding guide rail beam guide surface 10.

[0078] In this way, the guide surface spacing displacement device 2 can give the first guide wheel 401a a sufficient lateral adjustment range, ensuring that the first guide wheel 401a can always contact the guide surface 10 of the guide rail beam during measurement, and at the same time can well ensure that the first guide wheel 401a does not deviate, and at the same time, the measurement method of the spacing between the guide surfaces 10 of the guide rail beam is a contact measurement of the first guide wheel 401a, thereby improving the measurement accuracy.

[0079] In some embodiments, Figure 3 As shown, the first guide wheel group further includes a second guide wheel assembly 402 , which is arranged on the same side as the first guide wheel assembly 401 , and the second guide wheel assembly 402 is detachably connected to the workbench 1 .

[0080] In some embodiments, Fig. 9 As shown, the second guide wheel assembly 402 includes a second guide wheel 402a, a second guide wheel bracket and a spring support device 402e, the second guide wheel bracket includes a first bracket 402f and a second bracket 402c, the spring support device 402e includes a mounting plate and a spring, the spring support device 402e is connected to the first end of the first bracket 402f through the mounting plate, the spring support bolt 402d passes through the mounting plate and the baffle at the second end of the second bracket 402c in sequence, and the baffle can be designed to abut against the spring of the spring support device 402e. The second guide wheel 402a is rotatably mounted on the first end of the second bracket 402c through the second guide wheel fixing bolt 402b, and the second end of the first bracket 402f is detachably connected to the workbench 1, for example, the second end of the first bracket 402f can be fastened to the workbench 1 using the first bracket bolt 402g.

[0087] Based on the above technical solution, the use process of the guide rail beam guide surface spacing detection vehicle of the utility model is as follows:

[0088] Initially, the guide rail beam guide surface spacing detection vehicle can be in Figure 4 The folded state shown, then, the first folding workbench 101, the second folding workbench 102 and the fixed workbench 103 are unfolded, and the slider 105 is moved, and the slider locking member 106 is used to make the first folding workbench 101, the second folding workbench 102 and the fixed workbench 103 in the unfolded state.

[0089] The first guide wheel assembly 401 and the second guide wheel assembly 402 are installed at the bottom of the first folding workbench 101 , and the third guide wheel assembly 403 is installed at the bottom of the second folding workbench 102 .

[0090] Place the guide surface spacing detection vehicle of the guide rail beam as a whole on the guide rail beam, so that the universal running wheel 3 falls on the guide rail beam running surface 9, then make the third guide wheel assembly 403 abut against the guide surface 10 of the guide rail beam on one side, and then adjust the first guide wheel assembly 401 and the second guide wheel assembly 402, so that the first guide wheel assembly 401 and the second guide wheel assembly 402 abut against the guide surface 10 of the guide rail beam on the other side, wherein the first guide wheel assembly 401 can be adjusted by the guide surface spacing displacement device 2, so that the guide surface spacing detection vehicle of the guide rail beam can adapt to different guide surface 10 spacings of the guide rail beams.

[0091] The data acquisition device 6, the computer 7 and the power supply 8 are installed on the workbench 1, so that the data acquisition device 6 is signal-connected with the first displacement detection device 5 and the second displacement detection device 401d respectively.

[0092] In this way, the guide rail beam guide surface spacing detection vehicle is driven to move along the guide rail beam. When encountering a curved position, it can be automatically identified and guided due to the guiding effect of the first guide wheel assembly 401, the second guide wheel assembly 402 and the third guide wheel assembly 403. When encountering a certain deformed position on the guide rail beam guide surface 10, the first guide wheel assembly 401 will move in a direction perpendicular to the guide rail beam guide surface 10, and the first displacement detection device 5 detects the displacement of the first guide wheel assembly 401, which indicates the deformation of the guide rail beam guide surface 10. At the same time, the second displacement detection device 401d records in real time the movement distance of the guide rail beam guide surface spacing detection vehicle from the starting position along the direction parallel to the guide rail beam guide surface 10, and the movement distance indicates the deformation position of the guide rail beam guide surface 10. The first displacement detection device 5 and the second displacement detection device 401d transmit information to the data acquisition device 6, and the data acquisition device 6 feeds back the information to the computer 7, so that the staff can know the deformation position and deformation of the guide rail beam guide surface 10 in real time, which is convenient for timely repair.

[0093] Patent document CN 215766916 U discloses a track beam measuring vehicle, which has a large overall size, a large mass, and a complex structure, and is inconvenient to carry for transportation; at the same time, the line of the rail-type rubber-wheel system is generally an elevated bridge, and the test of the rail beam needs to be measured after the rail beam is erected. At this time, the platform and electromechanical equipment have not been completed, and the line is not smooth. It is inconvenient to disassemble and transport the measuring vehicle on the line; the inner spacing measurement device adopts a laser ranging sensor and an infrared ranging sensor. When encountering the joints of the rail beam and the bolt holes of the finger plate during measurement, these areas will be passed through, which is easy to generate abnormal measurement data; the running wheels are connected to the universal joints and driven by the motor to walk, and manual identification of the curved walking section is required. It does not have a free steering function and there is a possibility of deviation when traveling on the curved track beam.

[0094] Compared with the patent document CN215766916U, the main body of the guide rail beam guide surface spacing detection vehicle of the utility model is made of aluminum profiles, which ensures strength while reducing weight, has a folding function, reduces the volume of the detection vehicle, and is conducive to the transportation and carrying of the detection vehicle. A contact-type guide wheel mechanism is used to detect the spacing change of the guide surface 10 of the guide rail beam, and an infrared laser displacement sensor is used to indirectly measure the contact displacement change of the guide wheel mechanism to obtain the spacing change of the guide surface 10 of the guide rail beam, avoiding the influence of the guide beam joint, the finger plate bolt hole, etc., making the detection data more real and reliable. Through the guide mechanism composed of the first guide wheel assembly 401, the second guide wheel assembly 402 and the third guide wheel assembly 403 and the running mechanism composed of the universal running wheel 3, it can be ensured that the guide rail beam guide surface spacing detection vehicle does not deviate when traveling, and the accuracy of the detection data is guaranteed; and the guide mechanism has a large adjustment range and can adapt to the measurement of the guide rail beams of each line. The measurement efficiency of the guide rail beam guide surface 10 spacing of the guide rail type rubber wheel system is improved.
