Description
Technical Field
[0001] The utility model relates to the technical field of track measurement equipment, in particular to a rail bottom slope measuring device used for rail transportation. Background Art
[0002] Rail bottom slope refers to the transverse slope formed between the rail bottom and the track plane. Properly setting the rail bottom slope can make the rail axis force more uniform, improve the lateral stability of the rail, reduce uneven wear of the rail head, reduce plastic deformation of the rail head, and extend the service life of the rail. Therefore, it is necessary to periodically use a rail bottom slope measuring device to check whether the rail bottom slope meets the standard so as to promptly detect and adjust the rail bottom slope setting to ensure the safe and stable operation of rail transportation. In actual application, the rail bottom slope measuring device needs to be placed under the rail and make the side of the rail close to the device. Then, it is moved along the rail to complete the detection of the bottom slope of the rail at various locations. However, there are sleepers installed at certain intervals under the rail. As a result, when the rail bottom slope measuring device is moved a certain distance under the rail, it needs to be removed and placed at another location between the sleepers and moved again close to the side of the rail. Frequently pressing the measuring device close to the side of the rail not only easily creates gaps, but also easily causes the measuring device to shift during movement, thereby affecting the accuracy of the measurement results. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a rail bottom slope measuring device for rail transit, so as to solve the problem in the existing technology that frequently placing the measuring device close to the side of the rail not only easily leads to gaps, but also easily causes deviation of the measuring device during movement, thereby affecting the accuracy of the measurement results.
[0004] To achieve the above-mentioned object, the present invention adopts the following technical solution: a rail bottom slope measuring device for rail transportation, comprising a rail bottom slope detector body, and an adjustable positioning frame connected to the rail bottom slope detector body, wherein the adjustable positioning frame comprises:
[0005] A telescopic rod structure, arranged in a horizontal direction and having retaining blocks connected at both ends thereof for slidingly connecting to corresponding rails, the telescopic rod structure comprising a fixed rod and an extension rod slidably connected thereto;
[0006] A connecting rod, the connecting rod being arranged in a vertical direction and having one side of its bottom end connected to the rail bottom slope detector body, the connecting rod being slidably connected to the extension rod and being restricted by a first adjustable limiting structure so that the connecting rod only slides in a horizontal direction;
[0007] A movable guide structure, one end of which is connected to the fixed rod and the other end of which is horizontally arranged to be slidably connected to the connecting rod, and then a second adjustable limiting structure is used to limit the sliding distance of the connecting rod in the horizontal direction.
[0008] Compared with the prior art, the present invention has the following beneficial effects:
[0009] The rail bottom slope measuring device is connected by sliding a fixed rod and an extension rod to adjust the distance between the two holding blocks according to the distance between the two rails, so that the two holding blocks are stably slidably connected to the two rails, and the connecting rod is moved in the vertical direction and the extension rod is moved in the horizontal direction, so that the rail bottom slope detector body is placed at the bottom of the rail on one side, and then the sliding of the connecting rod and the extension rod is restricted by the first adjustable limiting structure so that only the connecting rod can slide in the horizontal direction. At the same time, the movable guide structure reinforces the fixed rod and the connecting rod, and the second adjustable limiting structure limits the sliding distance of the connecting rod in the horizontal direction. During the measurement process, when the rail bottom slope detector body moves to the sleeper, the rail bottom slope detector body moves stably in the horizontal direction with the minimum distance to cross the sleeper and return to the bottom of the rail to continue measuring, so as to ensure that the rail bottom slope detector body is closely attached to the bottom of the rail, and keeps it consistent with the motion trajectory and the rail when the rail bottom slope detector body moves, thereby ensuring the accuracy of the rail bottom slope detection result.

DETAILED DESCRIPTION
[0015] The present invention is further described in detail below through specific implementation methods:
[0016] like Figure 1-Figure 4 As shown, an embodiment of the present utility model proposes a rail bottom slope measuring device for rail transit, including a rail bottom slope detector body 1, and an adjustable positioning frame connected to the rail bottom slope detector body 1, the adjustable positioning frame including a telescopic rod structure 2, a connecting rod 3 and a movable guide structure 4, the telescopic rod structure 2 is arranged in the horizontal direction and both ends of which are connected to a retaining block 21 for slidingly connecting to the corresponding rail, the telescopic rod structure 2 including a fixed rod 22 and an extension rod 23 slidingly connected thereto; the connecting rod 3 is arranged in the vertical direction and one side of its bottom end is connected to the rail bottom slope detector body 1, after the connecting rod 3 is slidably connected to the extension rod 23, it is restricted by a first adjustable limiting structure 24 so that only the connecting rod 3 slides in the horizontal direction; one end of the movable guide structure 4 is connected to the fixed rod 22 and the other end is horizontally arranged to be slidably connected to the connecting rod 3, and then the second adjustable limiting structure 5 is used to limit the sliding distance of the connecting rod 3 in the horizontal direction.
[0017] The rail bottom slope measuring device is connected by sliding the fixed rod 22 and the extension rod 23 to adjust the distance between the two holding blocks 21 according to the distance between the two rails, so that the two holding blocks 21 are stably connected to the two rails by sliding. The connecting rod 3 is moved in the vertical direction and the extension rod 23 is moved in the horizontal direction to place the rail bottom slope detector body 1 at the bottom of the rail on one side. Then, the sliding of the connecting rod 3 and the extension rod 23 is restricted by the first adjustable limiting structure 24 so that only the connecting rod 3 can slide in the horizontal direction. At the same time, the guide structure 4 is moved to the fixed rod 22 and the extension rod 23. The rod 22 and the connecting rod 3 are reinforced, and the second adjustable limit structure 5 limits the sliding distance of the connecting rod 3 in the horizontal direction. During the measurement process, when the rail bottom slope detector body 1 moves to the sleeper, the rail bottom slope detector body 1 moves stably in the horizontal direction with the minimum distance to cross the sleeper and then return to the bottom of the track to continue measuring, so as to ensure that the rail bottom slope detector body 1 is close to the bottom of the track and keeps the motion trajectory and the track consistent when the rail bottom slope detector body 1 moves, thereby ensuring the accuracy of the rail bottom slope detection result.
[0018] In order to better understand the present solution, the structures of the telescopic rod structure 2, the retaining block 21, the first adjustable limiting structure 24 and the second adjustable limiting structure 5 will be further optimized below.
[0019] like Figure 1 and Figure 2 As shown, according to another embodiment of the present invention, a rail bottom slope measuring device for rail transit is provided, wherein there are two extension rods 23, one end of the two extension rods 23 is slidably connected to the two ends of the fixed rod 22 in a one-to-one manner and both are fixed by locking members, and the other end of the two extension rods 23 is connected to the two retaining blocks 21 in a one-to-one manner.
[0020] In this embodiment, the fixed rod 22 is a square tube, and the two extension rods 23 are both square rods. One end of the two extension rods 23 is slidably connected to the two ends of the fixed rod 22 in a one-to-one manner. The locking member can be a locking bolt threadedly connected to the fixed rod 22. By rotating the locking bolt to abut against the outer wall of the extension rod 23, the extension rod 23 and the fixed rod 22 are locked.
[0021] By adjusting the two extension rods 23 to slide relative to the fixed rod 22, the distance between the two holding blocks 21 is adjusted, so that the two holding blocks 21 are slidably connected to the two rails in a one-to-one correspondence.
[0022] In order to make the two retaining blocks 21 quickly and relatively stably connected to the two rails for sliding, the bottoms of the two retaining blocks 21 are formed with connection notches for the tops of the rails to be embedded in. Here, the two retaining blocks 21 are both in an inverted "U" shape.
[0023] like Figure 1 and Figure 3 As shown, according to another embodiment of the present invention, a rail bottom slope measuring device for rail transit, wherein the top wall of the extension rod 23 extends toward its bottom wall to form a first guide hole 6, and the connecting rod 3 freely passes through the first guide hole 6 and slides horizontally in the first guide hole 6; the first adjustable limiting structure 24 includes a second guide hole 241, an adjustment hole 242 and a limit block 243, the second guide hole 241 is opened on the corresponding extension rod 23 and is arranged perpendicular to the first guide hole 6; there are multiple adjustment holes 242 and they are arranged at intervals in the vertical direction on the connecting rod 3, and each adjustment hole 242 is opened in the horizontal direction on the connecting rod 3; the limit block 243 passes through any adjustment hole 242 and the second guide hole 241 and slides horizontally in the second guide hole 241.
[0024] In this embodiment, the first guide hole 6 and the second guide hole 241 are arranged in a "cross" shape on the extension rod 23. The first guide hole 6 is for the connecting rod 3 to pass through the extension rod 23 in the vertical direction, and the connecting rod 3 moves in the horizontal direction in the first guide hole 6, and the connecting rod 3 can also move in the vertical direction. After the connecting rod 3 is moved to arrange the position between the rail bottom slope detector body 1 and the track to be measured, the second guide hole 241 is aligned with one of the adjustment holes 242, and the limit block 243 passes through the aligned second guide hole 241 and the adjustment hole 242 to lock the connecting rod 3, and the connecting rod 3 cannot move in the vertical direction. The limit block 243 can move in the horizontal direction in the second guide hole 241, and the connecting rod 3 can move in the horizontal direction in the first guide hole 6, so that when encountering a sleeper during the track measurement process, the track can be continued to be measured by crossing the sleeper.
[0025] After the different adjustment holes 242 are aligned with the second guide holes 241 , they are passed through by the limiting blocks 243 for limiting, so that the rail bottom slope detector body 1 can be adjusted to different height positions.
[0026] like Figure 1 and Figure 4 As shown, according to another embodiment of the present utility model, a rail bottom slope measuring device for rail transit, wherein the horizontally arranged end of the movable guide structure 4 extends from its top wall to its bottom wall to provide a third guide hole 7, the connecting rod 3 freely passes through the third guide hole 7 and slides horizontally in the third guide hole 7, and the third guide hole 7 divides the horizontally arranged end of the movable guide structure 4 into two guide sections distributed front and back; the second adjustable limiting structure 5 includes a plug-in hole 51 and a limiting block 52, and a plurality of the plug-in holes 51 are arranged at intervals in the horizontal direction on each guide section, and the plug-in holes 51 are perpendicular to and connected to the third guide hole 7; there are two limiting blocks 52, and the two limiting blocks 52 respectively pass through the corresponding two plug-in holes 51 on the two guide sections to limit the connecting rod 3 to slide between the two limiting blocks 52.
[0027] In this embodiment, the two limiting blocks 52 are respectively located on the left and right sides of the connecting rod 3. The cooperation of the two limiting blocks 52 limits the distance that the connecting rod 3 can move horizontally in the third guide hole 7. During the measurement process, the connecting rod 3 slides and contacts with the limiting block 52 on the right, and the rail bottom slope detector body 1 moves to the sleeper. The staff moves the connecting rod 3 to the left until the connecting rod 3 contacts with the limiting block 52 on the left. At this time, the rail bottom slope detector body 1 just moves out from the bottom of the track; then the staff pushes the fixing rod 22 forward, and the rail bottom slope detector body 1 passes over the sleeper; then the staff moves the connecting rod 3 to the right until the connecting rod 3 contacts with the limiting block 52 on the right. At this time, the connecting rod 3 drives the rail bottom slope detector body 1 to move to the side of the track, that is, the rail bottom slope detector body 1 is partially placed at the bottom of the track and partially contacts the side of the track. The staff continues to push the fixing rod 22 forward to perform measurements.
[0028] In order to strengthen the restriction on the connecting rod 3, the second adjustable limiting structure 5 also includes a connecting slider 53 and a constraint block 54. The connecting slider 53 is fixedly connected to the limiting block 52 on the side of the track to be measured. The constraint block 54 is slidably connected to the connecting slider 53 along the length direction of the limiting block 52, and the distance between the constraint block 54 and the corresponding limiting block 52 is just enough to place the connecting rod 3 therebetween.
[0029] In this embodiment, the limiting block 52 facing the side of the track to be measured is the right limiting block 52. When the connecting rod 3 moves to contact the right limiting block 52, the restraining block 54 is slid to position the connecting rod 3 between the right limiting block 52 and the restraining block 54 to stabilize the connecting rod 3 during the measurement process. When the rail bottom slope detector body 1 moves to the sleeper, the restraining block 54 needs to be slid in the opposite direction to release the restraint on the connecting rod 3. The connecting rod 3 can then move stably horizontally between the two limiting blocks 52 to cross the sleeper and continue measuring.
[0030] A sliding groove for the restraining block 54 to slide can be provided on the connecting slider 53 to make the sliding adjustment of the restraining block 54 more stable.
[0031] In order to improve the stability of the restriction on the connecting rod 3, there are two constraint blocks 54 and one end of the two constraint blocks 54 is connected by a connecting bar, one constraint block 54 is located above the horizontal arrangement end of the movable guide structure 4 and the other constraint block 54 is located below the horizontal arrangement end of the movable guide structure 4.
[0032] The two constraint blocks 54 are connected by a connecting bar to form a whole to slide synchronously, and the two constraint blocks 54 cooperate with the limiting block 52 on the right to more stably limit the horizontal movement of the linkage rod 3.
[0033] like Figure 1 and Figure 2 As shown, according to another embodiment of the present invention, a rail bottom slope measuring device for rail transit, wherein the movable guide structure 4 includes a positioning rod 41 and an expansion rod 42. The positioning rod 41 is arranged vertically and its bottom end is fixedly connected to the fixed rod 22; the expansion rod 42 is arranged horizontally and one end is fixedly connected to the top of the positioning rod 41. The second adjustable limiting structure 5 is connected between the other end of the expansion rod 42 and the connecting rod 3. To reasonably design the movable guide structure 4.
[0034] In this embodiment, the two restraining blocks 54 are specifically distributed above and below the expansion rod 42 .
[0035] When using:
[0036] When the staff needs to inspect the rail bottom slope, the staff can first slide the extension rod 23 so that the extension rod 23 drives the retaining block 21 to move to a suitable position until the two retaining blocks 21 can move to the two rails for connection, and then use the locking piece to lock the extension rod 23 and the fixed rod 22;
[0037] Then the staff can slide the connecting rod 3 in the vertical and horizontal directions, and drive the rail bottom slope detector body 1 to contact the bottom end of the track through the connecting rod 3;
[0038] Then the staff inserts the limit block 243 into the aligned adjustment hole 242 and the second guide hole 241, and the movement of the connecting rod 3 in the vertical direction is restricted;
[0039] Then the staff needs to slide the connecting rod 3 horizontally, so that the connecting rod 3 drives the rail bottom slope detector body 1 to move until it contacts the side of the track. At this time, the rail bottom slope detector body 1 is partially placed at the bottom of the track and partially contacts the side of the track;
[0040] When the rail bottom slope detector body 1 encounters a sleeper, the rail bottom slope detector body 1 moves horizontally across the sleeper by the required distance to insert the two limiting blocks 52 into the corresponding two insertion holes 51, wherein the limiting block 52 on the right side contacts the connecting rod 3;
[0041] Continue to slide the constraint block 54 to clamp the connecting rod 3 between the limiting block 52 and the constraint block 54 on the right side. Then the staff can push the positioning rod 41 to make the positioning rod 41 drive the rail bottom slope detector body 1 to move. The movement trajectory of the rail bottom slope detector body 1 will be limited by the holding block 21, so that it can be consistent with the track trajectory, thereby ensuring the accuracy of the rail bottom slope detection result of the rail bottom slope detector body 1.
[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
