DETAILED DESCRIPTION

[0024] The specific embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application, but are not used to limit the scope of the present application.

[0025] A preferred embodiment of a rail measurement and adjustment tool according to the present application is shown in Figures 1 to 6 The rail measurement and adjustment tool includes a measurement unit and an adjustment unit. The measurement unit is used to detect the levelness, parallelism and spacing of the rail 10. The adjustment unit is used to adjust the height and position of the rail 10 after the measurement unit completes detection.

[0026] As shown in Figures 1 to 4 The measurement unit includes two sets of measuring trolleys 1. The two sets of measuring trolleys 1 are arranged at intervals along the extension direction of the rail 10. The interval arrangement of the two sets of measuring trolleys 1 can increase the size of the measurement unit in the extension direction of the rail 10, avoid the levelness difference of the rail 10 being too small due to the distance being too small, and improve the accuracy of the detection result. The two sets of measuring trolleys 1 are the same in structure, and only one set is described here as an example.

[0027] The measuring trolley 1 includes a walking frame 11 and a walking wheel 12. The walking wheel 12 is arranged at the bottom of the walking frame 11 and is used to move along the extension direction of the rail 10. The walking frame 11 is of a frame structure, which can reduce the mass of the measuring trolley 1. Four walking wheels 12 are arranged at the bottom of the walking frame 11. The four walking wheels 12 are distributed on both sides of the walking frame 11 in pairs. The spacing between the walking wheels 12 is the same as the spacing of the rail 10 to meet the requirement of walking on the rail 10. In this embodiment, the size of the measuring trolley 1 is 1200mm in length, 500mm in width and 1100mm in height. The spacing between the walking wheels 12 on both sides of the walking frame 11 is adjustable to adapt to the requirement of detecting rails 10 of different spacing. Specifically, a thread is arranged on the assembly shaft of the walking frame 11. The walking wheels 12 are assembled on the walking frame 11 through nuts on both sides. The spacing between the walking wheels 12 can be adjusted by adjusting the position of the nuts. The specific structure is prior art and is not described in detail here.

[0028] The walking frame 11 of each measuring trolley 1 is provided with a measuring tube 2, the measuring tube 2 is vertically arranged on the walking frame 11, and the measuring tube 2 is arranged at least in two groups, and the two groups of measuring tubes 2 are located on both sides of the walking frame 11 to correspond to the rails 10. In this embodiment, two groups of measuring tubes 2 are arranged on each measuring trolley 1, and the two groups of measuring tubes 2 are arranged on the rear side of the measuring trolley 1, wherein the advancing direction of the measuring trolley 1 is defined as the front side, and the other side is the rear side, and the two groups of measuring tubes 2 are located on both sides of the measuring trolley 1 to detect the levelness of the pair of rails 10.

[0029] The two groups of measuring tubes 2 are connected to each other through the communication pipe 3, so that the two groups of measuring tubes 2 form a communicating vessel structure, and the communication pipe 3 is communicated with the bottom end of the measuring tube 2. After the measuring tube 2 is connected to form a communicating vessel structure through the communication pipe 3, under the action of atmospheric pressure, when the two groups of measuring trolleys 1 are at the same height, the liquid level in each group of measuring tubes 2 is at the same height, and when the measuring trolley 1 is not horizontal, the liquid level in each group of measuring tubes 2 will have a height difference, so by determining the height difference of each group of measuring tubes 2, whether the measuring trolley 1 is at the same height can be determined, thereby judging whether the rails 10 are horizontal, and realizing the levelness detection of the rails 10.

[0030] As shown in Figure 5 With Figure 6 The adjusting unit includes a moving frame 4, a jacking mechanism 5 and a rail clamp 6, the bottom of the moving frame 4 is provided with a universal wheel 41, the jacking mechanism 5 is arranged on the moving frame 4, and the rail clamp 6 is arranged at the bottom of the jacking mechanism 5. Under the action of the universal wheel 41, the moving frame 4 can drive the jacking mechanism 5, the rail clamp 6 and the rails 10 to move, and adjust the position of the rails 10.

[0031] The jacking mechanism 5 is used to drive the vertical movement of the rail clamp 6, and the rail clamp 6 is used to clamp and fix the rail 10 to be adjusted. When the measuring unit detects that the levelness of the rails 10 has a difference, the rail clamp 6 can be used to clamp and fix the rails 10 first, the jacking mechanism 5 drives the rail clamp 6 to rise, and then drives the rails 10 to rise, and the moving frame 4 moves under the action of the universal wheel 41, thereby adjusting the position and height of the rails 10.

[0032] The measuring trolley 1 of the rail measurement and adjustment tool is provided with multiple groups of measuring tubes 2. Since the measuring tubes 2 are connected through the communication tubes 3 and form a communication vessel structure, when detecting whether the rail 10 is horizontal, liquid can be first injected into the measuring tubes 2. When the rail 10 is kept horizontal, the measuring trolley 1 is in a horizontal state. Under the principle of the communication vessel, the liquid levels in the respective measuring tubes 2 are the same. When the rail 10 is not horizontal, there is a height difference in the liquid levels in the measuring tubes 2. The levelness of the rail 10 can be detected by observing the liquid levels in the respective measuring tubes 2. The measuring trolley 1 moves along the rail 10 through the traveling wheels 12. During the movement, the levelness of the rail 10 can be detected, and the efficiency is high. When there is a difference in the liquid levels in the measuring tubes 2 of the measuring trolley 1, the moving frame 4 of the adjustment unit moves to the upper side of the rail 10. After the rail clamp 6 clamps the rail 10, the rail clamp 6 is lifted through the jacking mechanism 5. The rail 10 is lifted under the action of the rail clamp 6. Then, the moving frame 4 moves under the action of the universal wheels 41 and drives the rail 10 to move. The height and position of the rail 10 are adjusted, so that the rail 10 is kept in a horizontal state. The levelness of the rail 10 is adjusted in real time, and the adjustment efficiency of the rail 10 is improved in cooperation with the measuring trolley 1.

[0033] Preferably, the measuring tube 2 comprises a glass tube 21 and a flexible tube 22 connected to the bottom end of the glass tube 21. The flexible tube 22 is used to communicate with the communication tube 3. The traveling frame 11 is provided with a measurement scale 7 for fixing the glass tube 21.

[0034] As shown in Figure 2 With Figure 3 the bottom end of the glass tube 21 is connected to the flexible tube 22, and the bottom end of the flexible tube 22 is connected to the communication tube 3. The glass tube 21 is made of transparent material. The measurement scale 7 has a height scale. The liquid level height value on the measurement scale 7 can be read through the glass tube 21 and the scale of the measurement scale 7, so that the liquid level height data in the glass tube 21 can be accurately viewed by the detection personnel.

[0035] In this embodiment, the measurement scale 7 is a steel ruler. When detecting the levelness of the rail 10, the glass tube 21 is fixed on the measurement scale 7. If the rail 10 is horizontal, the measurement data values of the four measuring tubes 2 should be zero when subtracted two by two. The scale data corresponding to the liquid level of the four glass tubes 21 are read. The difference between the four data is compared, so that the levelness of the rail 10 is judged.

[0036] Specifically, for example, the liquid level of the glass tube 21 on the left front side of the four groups of measuring tubes 2 is 120 mm, the liquid level of the glass tube 21 on the right front side is 110 mm, the liquid level of the glass tube 21 on the left rear side is 120 mm, and the liquid level of the glass tube 21 on the right rear side is 110 mm. Then, the front and rear levels of the left rail 10, the front and rear levels of the right rail 10, the right side of the front rail 10 being 10 mm higher, and the right side of the rear rail 10 being 10 mm higher can be obtained. The height of the rail 10 can be adjusted by the adjusting unit until the liquid levels of the four groups of measuring tubes 2 are the same.

[0037] The flexible tube 22 is connected between the glass tube 21 and the communication tube 3. The flexible tube 22 can be flexibly deformed. When there is a difference in the levelness of the rail 10, the height of the communication tube 3 will change or be skewed. At this time, the flexible tube 22 will be flexibly deformed to compensate for the change in the height of the communication tube 3, so that the glass tube 21 will not be deformed and damaged.

[0038] The installation height of the glass tube 21 will not affect the detection result. The reading of the liquid level inside the glass tube 21 is mainly observed. Even when there is a difference in the installation height of the measuring scale 7, the measurement result will not be affected. When the trolley is horizontal, the difference in the reading of the measuring scale 7 at the same position is a fixed value.

[0039] Preferably, the measuring scale 7 comprises a scale 71 fixedly connected with the walking frame 11 and a tube clamp 72 fixed on the scale 71, and the glass tube 21 is fixedly worn in the tube clamp 72. The scale 71 is used to read the liquid level height in the glass tube 21.

[0040] As shown in Figure 2 As shown in Figure 3 The scale 71 is a steel ruler, which can directly read the liquid level height in the glass tube 21, and is convenient for directly determining the height difference of the liquid level. The tube clamp 72 is used to wear the glass tube 21, so that the glass tube 21 is attached to the steel ruler, ensuring the accuracy of the reading. In the embodiment, the length of the steel ruler is 300 mm, and the tube clamp 72 is welded and fixed on the steel ruler.

[0041] Preferably, the communication tube 3 comprises a plurality of horizontally arranged pipe lines 31 and a plurality of multi-way joints 32. Each pipe line 31 is supported and arranged on the walking frame 11, and the pipe lines 31 are connected with each other through the multi-way joints 32.

[0042] The pipe line 31 is arranged on the walking frame 11, and the walking frame 11 is used to support and fix the communication tube 3. In the embodiment, the pipe line 31 is connected by a plurality of rubber pipes, and the multi-way joint 32 is a four-way joint. According to the number of interfaces of the pipe line 31, the specific passage of the multi-way joint 32 can be determined according to actual needs.

[0043] Preferably, the walking frame 11 is further provided with a center monitoring device 8 for detecting the center line of the rail 10, the center monitoring device 8 comprising a support plate 81 fixedly arranged on the walking frame 11 and an indicating mark 82 vertically arranged at the bottom of the support plate 81, the indicating mark 82 being used to be located at the center line of the walking frame 11 to align the checking ruler for the center of the rail 10.

[0044] In addition to the levelness, the parallelism between the rails 10, i.e. whether the two groups of rails 10 always remain parallel, needs to be monitored. The center monitoring device can detect the parallelism of the rails 10 while the measuring trolley 1 is walking.

[0045] As shown in Figure 4 , both ends of the support plate 81 are fixedly arranged on the walking frame 11, and in this embodiment, the support plate 81 is fixedly welded with the walking frame 11. The indicating mark 82 is perpendicular to the support plate 81, and the indicating mark 82 is vertically arranged downward, and the bottom of the indicating mark 82 is provided with a sharp corner, and the indicating mark 82 is located on the center line of the walking frame 11, i.e. at the center position of the two groups of rails 10. The center position of each group of rails 10 is marked with a center line on the bottom surface, and by comparing the indicating mark 82 with the center line, the center monitoring of the rails 10 can be realized.

[0046] In this embodiment, the support plate 81 is made of a steel plate with a length of 1200mm, a width of 1100mm and a thickness of 5mm; the center line of the rail 10 can be connected and marked after the midpoint of the distance between the rails 10 is determined at the head and tail ends, and whether the rails 10 in the middle section are twisted and deviated can be judged by comparing the center monitoring device 8.

[0047] Preferably, the walking frame 11 is further provided with a measuring ruler 9 for measuring the distance between the rails 10, the measuring ruler 9 being horizontally fixedly arranged at the bottom of the walking frame 11.

[0048] As shown in Figure 2 , the measuring ruler 9 can measure the distance between the rails 10 to avoid the change of the distance between the rails 10 in the case of parallelism. In this embodiment, the measuring ruler 9 is made of a steel ruler with a length of 1200mm, a width of 50mm and a thickness of 5mm. During the walking process of the measuring trolley 1, the readings on the measuring ruler 9 corresponding to the single rail center of the rail 10 can be obtained, and the difference between the two readings is the distance between the two rails 10. For example, if the left reading of the measuring ruler 9 is 150mm and the right reading is 2160mm, then the distance between the two rails 10 at this position is 2010mm.

[0049] Preferably, the moving frame 4 is a portal structure, the moving frame 4 is straddled on both sides of the rail 10, the jacking mechanism 5 is arranged at the top of the moving frame 4, and the rail clamp 6 is arranged in the portal space of the moving frame 4.

[0050] The mobile frame 4 adopts a portal structure, and the portal space of the portal can be used to accommodate the rail 10 and the rail clamp 6, and provide stable support for lifting the rail 10. In the embodiment, the size of the mobile frame 4 is 200 mm in length, 200 mm in width, and 200 mm in height.

[0051] Preferably, the rail clamp 6 comprises a connecting rod 61, two clamping jaws 62, a driving rod 63, and a lifting screw 64. The two clamping jaws 62 are oppositely arranged to clamp the rail 10. The top ends of the two clamping jaws 62 are hingedly connected to the connecting rod 61. The driving rod 63 is hingedly connected to each clamping jaw 62 to drive the clamping jaw 62 to rotate. The top ends of the two driving rods 63 are hingedly connected to the bottom end of the lifting screw 64. The lifting mechanism 5 is threadedly connected to the lifting screw 64 to drive the lifting screw 64 to lift.

[0052] The top ends of the two clamping jaws 62 are hingedly connected to the connecting rod 61, and the hinged shafts are horizontally arranged so that the clamping jaws 62 can move in a vertical plane. The rail 10 is an I-shaped section, and when the two clamping jaws 62 are close to each other, the clamping jaws 62 can be clamped on the web of the rail 10 and hooked with the top plate to achieve clamping connection of the rail 10.

[0053] When the lifting screw 64 is lifted under the action of the lifting mechanism 5, the driving rod 63 is lifted. Since the hinged shaft of the driving rod 63 is hingedly connected to the clamping jaw 62, the driving rod 63 can drive the clamping jaws 62 to move close to each other. Therefore, when the lifting screw 64 is lifted, the driving rod 63 drives the clamping jaws 62 to clamp the rail 10 more tightly, and in turn drives the rail 10 to lift, thereby adjusting the height of the rail 10.

[0054] Preferably, the lifting mechanism 5 comprises a lifting ring 51 fixedly arranged at the top end of the mobile frame 4 and a lifting nut 52 threadedly connected to the lifting screw 64. The lifting screw 64 is arranged in the lifting ring 51. The lifting ring 51 is used to block the assembly of the lifting nut 52 along the axial direction of the lifting screw 64. The lifting nut 52 is further connected to a rotating handle.

[0055] The lifting ring 51 can limit the direction of the lifting screw 64 to avoid the lifting screw 64 from deviating. When the lifting nut 52 is rotated and drives the lifting screw 64 to lift, the lifting nut 52 has a downward movement tendency. Since the lifting nut 52 is blockingly assembled with the lifting ring 51 along the axial direction of the lifting screw 64, the lifting nut 52 cannot lift, and thus the lifting screw 64 can lift and drive the rail 10 to lift. The rotating handle is convenient for an operator to rotate the lifting nut 52.

[0056] Preferably, the clamping jaw 62 comprises an integral connecting arm 621 and a supporting table 622, the connecting arm 621 and the supporting table 622 are in L-shaped structure, the supporting table 622 is located at the bottom of the connecting arm 621, the top end of the connecting arm 621 is hinged with the connecting rod 61, the bottom end of the driving rod 63 is hinged with the middle part of the connecting arm 621, and the top surface of the supporting table 622 is used for lifting the rail 10.

[0057] The connecting arm 621 and the supporting table 622 are in L-shaped structure, the top surface of the supporting table 622 is used for lifting the rail 10, and the specific structure of the clamping jaw 62 is simplified, and the operation is simple and convenient.

[0058] The working process of the present application is as follows: the detection personnel injects water into the measuring pipe 2, pushes the measuring trolley 1 to move on the rail 10, observes the reading of the liquid level in the measuring pipe 2, the comparison between the indicating mark 82 of the central monitoring device 8 and the center line of the rail 10, and the reading corresponding to the monorail center of the measuring scale 9, judges the levelness, center line and spacing of the rail 10; when the data of the rail 10 is out of tolerance, the fastening nuts and the pressing pieces on both sides of the rail 10 are disassembled, so that the rail 10 is free; then the moving frame 4 is moved to the upper side of the rail 10, the lifting nut 52 is rotated to lower the rail clamp 6, the two clamping jaws 62 are sleeved into the rail 10, the lifting nut 52 is rotated to drive the rail clamp 6 to rise, when the rail 10 rises to a certain height, the moving frame 4 is pushed to move under the action of the universal wheel 41, the front and rear and left and right displacement adjustment of the rail 10 is realized, then the fastening nuts and the pressing pieces on both sides of the rail 10 under the rail 10 are disassembled, so that the rail 10 is free, the lifting nut 52 is rotated to lower the rail clamp 6, so that the rail 10 falls to the specified position, the fastening nuts and the pressing pieces on both sides of the rail 10 are tightened; the rail clamp 6 is lowered again, the adjusting unit can be taken off, and the adjustment of the rail 10 is realized; the above operation is repeated to complete the adjustment of the rail 10.
