Specific embodiments

[0026] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with specific embodiments.

If there are descriptions of terms such as first, second, etc., they are only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0029] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installation, connection, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0030] As Figure 1 shown, a roof support platform according to the present invention mainly includes a connection mechanism 1, a support mechanism 2, and a mounting mechanism 3.

[0031] As Figure 2 and Figure 3 shown, the connection mechanism 1 includes a fixed base plate 11 and a movable base plate 18.

[0032] The fixed base plate 11 is used to be connected to a column beside the train to be inspected. For example, clamping grooves 15 are provided on both sides of the top and / or bottom of the fixed base plate 11, and a connecting member 16 is connected to the clamping grooves 15. The connecting member 16 includes two clamping claws 161 and a bolt assembly 162. The two clamping claws 161 are respectively clamped on the clamping grooves 15 on both sides. At the same time, the clamping claws 161 are also clamped on the column, and the two clamping claws 161 are adjusted and locked by the bolt assembly 162 so as to fix and adjust the position of the fixed base plate 11 on the column. The combined structure of the clamping groove 15, the clamping claws 161, and the bolt assembly 162 is simple and reliable, making the installation and adjustment between the fixed base plate 11 and the column more convenient.

[0033] The movable base plate 18 is rotatably connected to the fixed base plate 11 and can rotate at least around the vertical direction, so that the movable base plate 18 can be folded at least to fit with the fixed base plate 11, or rotated to be perpendicular to the fixed base plate 11. For example, a plurality of first ear seats 13 are provided on one side edge of the fixed base plate 11, and a plurality of second ear seats 19 are provided on one side edge of the movable base plate 18. Through holes are vertically opened on both the first ear seats 13 and the second ear seats 19. A pin shaft 17 is used to insert into the through holes on both the first ear seats 13 and the second ear seats 19 at the same time so as to hinge the movable base plate 18 to the fixed base plate 11 and enable the movable base plate 18 to rotate around the vertical direction.

[0034] The support mechanism 2 is located above the train to be inspected. As Figure 1 shown, one end of the support mechanism 2 is connected to the movable base plate 18, so that the support mechanism 2 can also rotate at least around the vertical direction, enabling it to be mutually converted between at least two postures of being parallel to the train traveling direction or perpendicular to the train traveling direction.

[0035] The mounting mechanism 3 is slidably connected to the support mechanism 2 and can reciprocally slide at least along the length direction of the support mechanism 2.

[0036] In the present invention, various instruments for detecting trains are installed on the installation mechanism 3. Since the connecting mechanism 1 has the function of rotating and folding, it can make the installation and adjustment of the instruments more convenient. For example, columns and inspection corridors adjacent to the columns are usually arranged on both sides of the ceiling of the inspection shed, and the height of these corridors is basically flush with the top of the train. When installing the instruments, first carry the components of the platform of the present invention onto the corridor, then install the connecting mechanism 1 on the column within the range of 1 m to 2 m above the corridor, and then rotate the movable bottom plate 18 so that the operator can install the supporting mechanism 2 on the movable bottom plate 18 on the corridor. Subsequently, after installing the installation mechanism 3 on the supporting mechanism 2, install the instrument on the installation mechanism 3 and adjust the position of the installation mechanism 3 on the supporting mechanism 2 so that the installation mechanism 3 can be in a preset detection station on the supporting mechanism 2, thereby making the instrument in a suitable detection position. Finally, rotate the movable bottom plate 18 to make the supporting mechanism 2 perpendicular to the train traveling direction, and then the instrument can be used to detect the train.

[0037] When the position of the instrument needs to be adjusted, the supporting mechanism 2 can be rotated to a posture parallel to the train traveling direction. At this time, the entire supporting mechanism 2 is located on the corridor, and the operator can stand on the corridor to adjust the detection station of the installation mechanism 3 on the supporting mechanism 2, thereby adjusting the detection position of the instrument. After the adjustment is in place, rotate the supporting mechanism 2 to a posture perpendicular to the train traveling direction.

[0038] The present invention improves the convenience of instrument installation and debugging, reduces the labor intensity, reduces the danger of installation and debugging, and effectively improves the problem of installation and debugging accuracy.

[0039] To improve the reliability of the platform of the present invention, as Figure 2 shown, a plurality of first connection holes 12 can be opened on the fixed bottom plate 11, and at least a limiting surface 131 perpendicular to the plane where the fixed bottom plate 11 is located is provided on the first ear seat 13, and a second connection hole 14 is vertically opened on the limiting surface 131.

[0040] As Figure 3 shown, a third connection hole 110 is opened on the movable bottom plate 18, and a fourth connection hole 113 is also opened on one side edge of the movable bottom plate 18 close to the second ear seat 19.

[0041] There is a positional correspondence between the third connection hole 110 and the first connection hole 12, and there is also a positional correspondence between the fourth connection hole 113 and the second connection hole 14. Their positional correspondence is as follows: when the movable bottom plate 18 rotates to fit with the fixed bottom plate 11, the third connection hole 110 and the first connection hole 12 are aligned. At this time, the attitude can be called the working attitude, and the third connection hole 110 and the first connection hole 12 can be connected by a bolt assembly so that the support mechanism 2 can be firmly in the working attitude to prevent the instrument from moving during detection; when the movable bottom plate 18 rotates to be perpendicular to the fixed bottom plate 11, the fourth connection hole 113 and the second connection hole 14 are aligned. At this time, the attitude can be called the debugging attitude, and the fourth connection hole 113 and the second connection hole 14 can be connected by a bolt assembly so that the support mechanism 2 can be firmly in the debugging attitude to prevent the support mechanism 2 from rotating when adjusting the position of the installation mechanism 3.

[0042] To make the installation of the entire platform more convenient, as an alternative implementation, as Figure 3 shown, the upper part of the side of the movable bottom plate 18 away from the fixed bottom plate 11 has a plurality of hooks 111.

[0043] As Figure 4 shown, the support mechanism 2 includes a truss 22 and a receiving bottom plate 21 connected to one end of the truss 22. A slide rail 23 can be installed on the top of the truss 22 along the length direction of the truss 22, and the installation mechanism 3 is slidably connected to the slide rail 23 on the truss 22 and can reciprocate along the length direction of the truss 22.

[0044] As Figure 5 shown, a hanging hole 211 is opened in the upper part of the receiving bottom plate 21, and the receiving bottom plate 21 can be hung on the hook 111 through the hanging hole 211.

[0045] In this way, after installing the connecting mechanism 1 in the platform of the present invention on the column, the truss 22 can be quickly hung on the movable bottom plate 18 at least through the receiving bottom plate 21. Compared with the previous connection methods such as bolt connection or welding, the installation is faster and more convenient, with less labor intensity and higher safety.

[0046] To improve the accuracy of hanging, as Figure 3 shown, a plurality of protruding guide posts 112 can also be provided at the lower part of the side of the movable bottom plate 18 away from the fixed bottom plate 11. As Figure 5As shown, a number of guiding and limiting holes 212 are provided in the lower part of the receiving base plate 21. When making a hanging connection, first, the hanging hole 211 on the receiving base plate 21 is hooked on the hook 111 on the movable base plate 18, and then the guiding and limiting holes 212 on the receiving base plate 21 are aligned with the protruding guiding columns 112 on the movable base plate 18 and the protruding guiding columns 112 are inserted into the guiding and limiting holes 212 for guiding. In this way, through the guiding and limiting cooperation of the guiding and limiting holes 212 and the protruding guiding columns 112, the receiving base plate 21 can be correctly positioned at the preset position after being hung on the movable base plate 18 without deviation or skew.

[0047] After the support mechanism 2 is hung on the connection mechanism 1, obviously, the connection relationship between the two can be further strengthened by means of, for example, bolt connection. For example, as Figure 3 shown, a number of fifth connection holes 114 are provided on the movable base plate 18. As Figure 5 shown, a number of sixth connection holes 213 are provided on the receiving base plate 21. A bolt assembly is used to pass through the correspondingly positioned fifth connection holes 114 and sixth connection holes 213 to firmly connect the receiving base plate 21 and the movable base plate 18 together, avoiding, for example, the support mechanism 2 being separated from the connection mechanism 1 due to collision, thereby improving the safety of the platform described in the present invention.

[0048] Here, for the convenience of description, the end of the truss 22 close to the receiving base plate 21 can be called the proximal end, and the end of the truss 22 far from the receiving base plate 21 can be called the distal end. On the support mechanism 2, preferably, a limiting mechanism 24 and a locking mechanism 25 are also installed on the slide rail 23.

[0049] Among them, as Figure 4 shown, the limiting mechanism 24 is located on a section of the slide rail 23 close to the movable base plate 18, that is, the limiting mechanism 24 is located at the proximal end of the truss 22 for the convenience of personnel operation.

[0050] As Figure 9 shown, the locking mechanism 25 is connected to the installation mechanism 3.

[0051] Both the limiting mechanism 24 and the locking mechanism 25 can be clampers, and their functions are as follows: During the installation process of the platform described in the present invention, first, the limiting mechanism 24 is locked on a section of the slide rail 23 close to the receiving base plate 21, and then the installation mechanism 3 is slid close to the receiving base plate 21 and the locking mechanism 25 is locked. At this time, the position of the installation mechanism 3 on the slide rail 23 is jointly locked by the limiting mechanisms 24 and the locking mechanism 25 on both sides, thereby avoiding shaking during the installation process.

[0052] After the platform described in the present invention is installed, since the support mechanism 2 extends a certain distance, to prevent the support mechanism 2 from tilting downward, as Figure 4 andFigure 9 As shown, a tension plate 29 is further connected to the end of the truss 22 away from the receiving base plate 21 (i.e., the distal end). One end of a safety lifting rope 28 can be connected to the tension plate 29, and the other end of the safety lifting rope 28 is connected to a column, and the safety lifting rope 28 is in an upwardly inclined posture as a whole, so as to provide a pulling force to the distal end of the truss 22 and prevent the support mechanism 2 from tilting downward.

[0053] To facilitate adjusting the position of the installation mechanism 3 on the support mechanism 2, as Figure 4 shown, the support mechanism 2 may further include a position adjustment mechanism 26. The position adjustment mechanism 26 is installed on the truss 22 and is used to drive the installation mechanism 3 to reciprocate along the length direction of the truss 22.

[0054] As an optional implementation manner, as Figure 7 and Figure 8 shown, the position adjustment mechanism 26 may include a transmission seat 262 and a transmission member 263. A plurality of transmission seats 262 are dispersedly installed on the truss 22, and the transmission member 263 is assembled on the transmission seat 262 such that at least a part of the transmission direction of the transmission member 263 is parallel to the length direction of the truss 22. The installation mechanism 3 is connected to the transmission member 263.

[0055] The transmission seat 262 may be a gear seat with gears or a fixed pulley seat with pulleys. The transmission member 263 may be a chain that can mesh with gears, or a flexible cable that can span over pulleys, such as ropes, tapes, steel cables, chains, etc.

[0056] As Figure 7 shown, a plurality of transmission seats 262 are dispersedly installed on the truss 22, and at least one transmission seat 262 is installed at the proximal end and the distal end of the truss 22 respectively, and the remaining transmission seats 262 are dispersedly arranged on the upper and lower parts of the truss 22, as Figure 8 shown, so that after the transmission member 263 is assembled on the transmission seat 262, a loop can be formed, and the upper part of the transmission member 263 is parallel to the length direction of the truss 22. A connection seat 264 is connected to the upper part of the transmission member 263, and the installation mechanism 3 is connected to the connection seat 264 on the upper part of the transmission member 263.

[0057] When the transmission member 263 is pulled to rotate around the transmission seat 262, the installation mechanism 3 moves reciprocally along the length direction of the truss 22 on the truss 22, thereby realizing the adjustment of the instrument position.

[0058] The position adjustment mechanism 26 has two significant advantages: one is that the position of the installation mechanism 3 can be easily and accurately adjusted by pulling the transmission member 263; the other is that when the support mechanism 2 is in a posture perpendicular to the direction of travel of the train, the operator can directly adjust the position of the installation mechanism 3 at the far end in the corridor by pulling the transmission member 263 at the near end, that is, there is no need to rotate the support mechanism 2 to a posture parallel to the direction of travel of the train to adjust the position of the instrument, which greatly facilitates the adjustment of the instrument position, shortens the debugging time of the instrument, and significantly improves the debugging efficiency.

[0059] A crank 261 can be installed on the near-end transmission seat 262 for the convenience of personnel operation. At this time, the operator can rotate the crank 261 to replace the pulling transmission member 263, making it easier and more accurate to operate, and not easy to dirty hands.

[0060] After the installation mechanism 3 is adjusted to the right position, in order to avoid the position of the installation mechanism 3 being affected by misoperation, Figure 4 As shown, the support mechanism 2 may further include a position locking mechanism 27 , which is mounted on the truss 22 and is used to lock the position of the mounting mechanism 3 on the truss 22 .

[0061] As an optional implementation, Figure 6 and Figure 9 As shown, the position locking mechanism 27 may include a supporting seat 273 , a sliding seat 274 , a connecting rod 275 , a locking seat 276 and an operating rod 271 .

[0062] like Figure 9 As shown, the support seat 273 is installed at the far end of the truss 22 and is located below the mounting mechanism 3 at the detection station. The support seat 273 has a track arranged in parallel with the length direction of the truss 22.

[0063] The two sliding seats 274 are slidably connected to the rails on the supporting seat 273 and can slide back and forth along the length direction of the truss 22 .

[0064] The operating rod 271 is arranged parallel to the length direction of the truss 22 and extends from the proximal end to the distal end of the truss 22. A support 272 may be installed at the proximal end and the middle of the truss 22. The operating rod 271 is rotatably connected to the support 272 to ensure free rotation. The section of the operating rod 271 away from the receiving bottom plate 21 has an external thread and is rotatably arranged in the support seat 273. The two sliding seats 274 have internal threads. The operating rod 271 is screwed with the two sliding seats 274, and when the operating rod 271 is rotated, the two sliding seats 274 move toward or away from each other at the same time.

[0065] The lower ends of the two connecting rods 275 are respectively hinged to the two sliding seats 274, and the upper ends of the two connecting rods 275 are simultaneously hinged to the locking seat 276. At the same time, the locking seat 276 is located below the mounting mechanism 3 at the detection station.

[0066] When the operating rod 271 is rotated to make the two sliding seats 274 move towards each other, the locking seat 276 moves upward and finally abuts against the mounting mechanism 3, thereby locking the position of the mounting mechanism 3 on the truss 22; when the operating rod 271 is rotated to make the two sliding seats 274 move away from each other, the locking seat 276 moves downward and finally disengages from the contact with the mounting mechanism 3, so that the mounting mechanism 3 can freely adjust its position on the truss 22.

[0067] After the operator adjusts the position of the mounting mechanism 3 to the preset detection station through the position adjustment mechanism 26 in the corridor, the mounting mechanism 3 can be locked on the truss 22 through the position locking mechanism 27, so as to ensure that the instrument is fixed in position and stable in posture during detection.

[0068] To further enhance the locking effect of the position locking mechanism 27 on the mounting mechanism 3, as Figure 9 shown, the mounting mechanism 3 may include a sliding support 31 and a rack 32. The sliding support 31 is slidably connected to the support mechanism 2, preferably the sliding support 31 is slidably connected to the slide rail 23. The rack 32 is connected to the bottom of the sliding support 31. When the mounting mechanism 3 is at the detection station, the rack 32 is located above the locking seat 276.

[0069] The top of the locking seat 276 has a toothed structure that is used in pair with the rack 32.

[0070] In this way, when the locking seat 276 rises and abuts against the sliding support 31, the toothed structure on the top of the locking seat 276 will mesh with the rack 32 at the bottom of the sliding support 31. Compared with friction, the meshing between teeth is more reliable, and once the position of the sliding support 31 is locked by the meshing between teeth, it will no longer be possible to move.

[0071] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0072] The above preferred embodiments should not be regarded as limiting the present invention. The protection scope of the present invention should be defined by the scope of the claims. For those of ordinary skill in the art, without departing from the spirit and scope of the present invention, several improvements and refinements can also be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
