Description
Technical Field
[0001] This invention relates to the field of rail transit technology, and more specifically to an intelligent measuring trolley for rail transit. Background Technology
[0002] The rail transit measurement trolley is a device specifically designed for various measurement tasks in the rail transit field. It is widely used in the construction, maintenance, and inspection of rail transit systems such as subways, light rails, and railways. It has high measurement accuracy and efficiency, and can quickly acquire a large amount of track data, reducing errors and workload associated with manual measurement.
[0003] Because the inner side of the track wheel has a flange (25-30mm higher than the tread surface), when the trolley enters a curve, the flange contacts the side of the track body to force the wheelset to deflect along the curve direction through friction. Therefore, in the prior art, when it is necessary to remove the measuring trolley from the track, the flange creates a locking structure with the track, making it impossible to remove the trolley by horizontal movement. Usually, a crane is needed to lift the intelligent measuring trolley of the rail transit to a certain height before it is moved horizontally, or the measuring trolley is disassembled manually before removal. Both of these methods are cumbersome and inconvenient to use. Summary of the Invention
[0004] The purpose of this invention is to provide an intelligent measurement trolley for rail transit, solving the following technical problems:
[0005] The movement process of existing intelligent measuring vehicles is rather cumbersome.
[0006] The objective of this invention can be achieved through the following technical solutions:
[0007] An intelligent measuring trolley for rail transit includes a trolley frame with four sets of rail wheels for moving on a track body.
[0008] The bottom of the trolley frame is fixedly provided with a reinforcing crossbeam, which is slidably arranged on the base.
[0009] The base is equipped with a translation module, which is used to drive the reinforcing beam to slide on the base; the base is also equipped with a lifting module, which is used to drive the base to lift.
[0010] Preferably, multiple measuring sensors are arranged on both the front and rear sides of the vehicle frame, and each measuring sensor is electrically connected to a server fixedly arranged on the vehicle frame.
[0011] Preferably, the base has two sets of T-shaped sliding grooves symmetrically arranged, and the bottom of the reinforcing beam is correspondingly fixed with T-shaped sliding seats that are slidably connected to the T-shaped sliding grooves.
[0012] Preferably, the translation module includes racks symmetrically fixed to both sides of the base;
[0013] The reinforcing beam has translation motors fixedly mounted on both sides, and the drive end of the translation motors is fixedly mounted with gears that mesh with the rack.
[0014] Preferably, a support plate is provided on one side of the track body.
[0015] Preferably, two sets of support plates are symmetrically arranged below the base, and the positions of the two sets of support plates correspond to the positions of the track bodies on both sides;
[0016] The base is provided with an adjustment part, which is used to drive the support plate to move closer to or further away from the base.
[0017] Preferably, the adjusting part includes a bidirectional screw that is rotatably arranged at the bottom of the base. The end of the bidirectional screw is fixed to the output end of the lifting motor fixed on the base. Nuts are symmetrically spirally sleeved on the bidirectional screw. A push rod is hinged to the bottom of the nut. The other end of the push rod is hinged to one side of the support plate.
[0018] The support plate is fixedly equipped with telescopic rods, and the other end of the telescopic rods is inserted into a sleeve fixed to the bottom of the base.
[0019] Preferably, two sets of wedge plates are symmetrically arranged on both sides of the bottom of the support plate. An inclined guide surface is provided at one end of the wedge plates that are close to each other. The inclined guide surface corresponds to the arc-shaped part on the track body. The wedge plates are connected to the elastic mechanism arranged on the support plate.
[0020] The distance between the wedge plates on both sides is less than the width of the rail head of the track body.
[0021] Preferably, the elastic mechanism includes a limiting plate fixed to the wedge plate, and a guide rod that is slidably inserted into the limiting plate is correspondingly fixed on the support plate, and a telescopic spring is provided on the guide rod.
[0022] Preferably, inclined guide plates are fixedly arranged on the limiting plate, and the two opposing inclined guide plates are inclined in a direction away from each other;
[0023] The base is provided with a limiting frame at its bottom, and the bottom of the limiting frame is provided with guide wheels that correspond to the inclined guide plate.
[0024] An operating method for an intelligent measuring trolley used in rail transit includes the following steps:
[0025] The lifting module drives the base to rise, and the base drives the trolley frame to rise to a certain height through the reinforcing beam, driving the track wheels to separate from the track body.
[0026] The translation module drives the reinforcing beam to slide on the base, and the reinforcing beam synchronously drives the trolley frame and track wheels to translate towards one side of the track body.
[0027] After the trolley frame and track wheels are completely moved to one side of the track body, the base is removed.
[0028] The beneficial effects of this invention are:
[0029] (1) The present invention drives the base to rise through the lifting module. The base can drive the trolley frame to rise to a certain height through the reinforcing beam, thereby driving the track wheels to separate from the track body. Then, the reinforcing beam is driven to slide on the base through the translation module. The reinforcing beam drives the trolley frame and track wheels to translate towards one side of the track body. After the trolley frame and track wheels are completely translated to one side of the track body, the base can be removed. The present invention does not require the use of a crane to lift and remove the measuring trolley, nor does it require the disassembly and removal of the measuring trolley. It can achieve the effect of automatic removal and is more efficient.
[0030] (2) In this invention, when the measuring trolley moves to one side of the track body, the measuring trolley is positioned. The gear can be driven to rotate in the opposite direction by the translation motor. During the rotation, the gear can drive the base to slide at the bottom of the reinforcing beam so as to move the base back to the bottom of the reinforcing beam. This invention does not require manual removal of the base and has a higher degree of automation.
[0031] (3) In this invention, as the adjustment unit drives the support plate to move toward the direction closer to the track body, the support plate first drives the two wedge plates to move synchronously. The inclined guide surface of the wedge plate first contacts the arc part. Under the limiting action of the arc part, the two wedge plates can be driven to move away from each other. During the movement, the wedge plate can compress the elastic mechanism and generate elastic force. When the support plate contacts the rail head surface on the track body, the two wedge plates are just locked in the right angle slot of the track body. At this time, the upper surface of the wedge plate is attached to the lower surface of the rail head, which can achieve the effect of locking and limiting. When the translation module drives the trolley frame to shift away from the track body, even if the center of gravity of the measuring trolley changes, it will not cause the phenomenon of tilting, ensuring that the trolley frame moves smoothly.
[0032] (4) In this invention, when the measuring trolley is located on the support plate, the trolley frame is first supported by a set of support frames. The base is first driven to move to the track body on both sides by the translation module. The support plate is driven to descend to contact the track body by the adjustment part. The wedge plate and the rail head are engaged. Then the support frame is removed. The trolley frame can be moved back to the base by the translation module. The measuring trolley can then be moved to the track body. No crane equipment is needed for hoisting and moving throughout the process, which is more efficient. Attached Figure Description

[0046] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.
[0047] Example 1
[0048] Please see Figures 1-3 As shown, the present invention is an intelligent measuring trolley for rail transit, including a trolley frame 1, on which four sets of rail wheels 101 for moving on the track body 3 are provided; specifically, the intelligent vehicle trolley of this embodiment is electrically driven, which can drive the rail wheels 101 to rotate on the track body 3. The structure of the rail wheels 101 is the same as the track structure of train wheels in the prior art, so that the measuring trolley can accurately simulate the state of the wheels and the track body 3 of a rail vehicle during normal operation, and achieve the effect of accurate measurement.
[0049] In this embodiment, multiple measuring sensors 201 are evenly distributed on both the front and rear sides of the vehicle frame 1, and each measuring sensor 201 is electrically connected to the server 2 fixedly arranged on the vehicle frame 1; specifically, the measuring sensors 201 in this embodiment can be:
[0050] Track gauge sensor: Employs laser or inductive sensors to measure track gauge changes in real time;
[0051] Horizontal / Ultra-elevation sensors: using gyroscopes or inclinometers to detect the lateral tilt of the track and the superelevation value of curved sections.
[0052] In addition, the track wheel 101 is equipped with a mileage encoder to record the mileage of the trolley (accuracy up to ±5mm).
[0053] It should be noted that each measuring sensor 201 uploads data to server 2 via a wireless communication module (such as 4G / 5G), and generates a track health report in conjunction with the GIS system.
[0054] In this embodiment, please refer to Figures 3-5 A reinforcing crossbeam 102 is fixedly arranged at the bottom of the trolley frame 1, and the reinforcing crossbeam 102 is slidably arranged on the base 4; wherein, a translation module is provided on the base 4, and the translation module is used to drive the reinforcing crossbeam 102 to slide on the base 4.
[0055] Furthermore, a lifting module is also provided on the base 4, which is used to drive the base 4 to lift.
[0056] It can be explained that when the intelligent measuring trolley is removed from the track body 3, the base 4 is first driven to rise by the lifting module. The base 4 can drive the trolley frame 1 to rise to a certain height by the reinforcing beam 102, thereby driving the track wheels 101 to separate from the track body 3. Then, the reinforcing beam 102 is driven to slide on the base 4 by the translation module. The reinforcing beam 102 simultaneously drives the trolley frame 1 and the track wheels 101 to translate towards one side of the track body 3. After the trolley frame 1 and the track wheels 101 are completely translated to one side of the track body 3, the base 4 can be removed. In this embodiment, it is not necessary to use a crane to lift and remove the measuring trolley, nor is it necessary to disassemble and remove the measuring trolley. It can achieve the effect of automatic removal and is more efficient.
[0057] Example 2
[0058] Based on Example 1, in order to improve the stability of the reinforcing beam 102 sliding on the base 4, please refer to... Figures 3-4 The base 4 has two sets of T-shaped grooves 409 symmetrically arranged on it. The bottom of the reinforcing beam 102 is correspondingly fixed with T-shaped slide blocks 103 that are slidably connected to the T-shaped grooves 409. It can be explained that in this embodiment, by setting the T-shaped grooves 409 and T-shaped slide blocks 103 to slide the base 4 and the reinforcing beam 102, the stability of the reinforcing beam 102 sliding horizontally on the base 4 can be improved, and the guiding effect can be achieved. On the other hand, the base 4 and the reinforcing beam 102 can move synchronously on the track body 3. When the track wheel 101 drives the trolley frame 1 to move, the trolley frame 1 can drive the base 4 to move synchronously through the reinforcing beam 102.
[0059] In this embodiment, please refer to Figures 5-8 The translation module includes racks 402 symmetrically fixed on both sides of the base 4. Translation motors 403 are fixedly arranged on both sides of the reinforcing beam 102. The drive end of the translation motors 403 is fixedly arranged with gears 404 that mesh with the racks 402. It can be explained that when the reinforcing beam 102 is driven to move on the base 4, the translation motors 403 are started to drive the gears 404 to rotate. During the rotation, the gears 404 can drive the reinforcing beam 102 to slide on the base 4 by meshing with the racks 402, so as to synchronously drive the trolley frame 1 to move.
[0060] Correspondingly, after the measuring trolley moves to one side of the track body 3, the measuring trolley is positioned. In this embodiment, the translation motor 403 drives the gear 404 to rotate in the opposite direction. During the rotation, the gear 404 can drive the base 4 to slide at the bottom of the reinforcing beam 102, so as to move the base 4 back to the bottom of the reinforcing beam 102. In this embodiment, there is no need for manual removal of the base 4, and the degree of automation is higher.
[0061] As a further solution in this embodiment, please refer to Figures 1-2 A support plate 301 can be installed on one side of the track body 3 to support the measuring trolley after it is removed.
[0062] Please see Figures 5-8 Two sets of support plates 401 are symmetrically arranged below the base 4. The positions of the two sets of support plates 401 correspond to the positions of the track bodies 3 on both sides. The base 4 is provided with an adjustment part, which is used to drive the support plates 401 to move closer to or further away from the base 4. It can be explained that in the initial state, the track wheels 101 of the trolley frame 1 are in rolling contact with the track body 3, and the support plates 401 on both sides are separated from the track body 3. When it is necessary to drive the base 4 to rise, this embodiment can drive the support plates 401 on both sides to fall through the adjustment part. The support plates 401 first contact the track body 3, and then the adjustment part drives the support plates 401 to move further away from the base 4. Since the position of the support plates 401 remains unchanged, the effect of driving the base 4 to rise can be achieved under the reaction force.
[0063] In this embodiment, the adjustment unit includes a bidirectional screw 501 rotatably mounted on the bottom of the base 4. The end of the bidirectional screw 501 is fixed to the output end of the lifting motor 5 fixed on the base 4. Nuts 502 are symmetrically spirally mounted on the bidirectional screw 501. A push rod 503 is hinged to the bottom of the nut 502. The other end of the push rod 503 is hinged to one side of the support plate 401. A telescopic rod 505 is fixedly mounted on the support plate 401. The other end of the telescopic rod 505 is inserted into a sleeve 504 fixed to the bottom of the base 4. It can be noted that when driving the support plate 401 to rise and fall, in this embodiment, the bidirectional screw 501 is driven to rotate by the lifting motor 5. During the movement of the nuts 502 on the bidirectional screw 501, the support plate 401 can be driven to move by the push rod 503. Based on the limiting and guiding effect of the telescopic rod 505 and the sleeve 504 on the support plate 401, the support plate 401 can achieve a smooth rising and falling effect.
[0064] Please see Figure 10As prior art in this field, the track body 3 includes a rail head 302 and a rail web 303. The rail head 302 is fixed to the rail web 303, and the two form a T-shaped structure. A right-angle groove 304 is formed between the rail head 302 and the rail web 303. Arc-shaped portions 305 are provided on both sides of the rail head 302. Specifically, the rail head 302 contacts the wheel and bears the rolling pressure of the wheel. The rail web 303 connects the rail head 302 and the rail base, enhancing the overall strength of the rail. The track body 3 in this embodiment is a track structure in the prior art, and this embodiment will not elaborate on it.
[0065] Furthermore, when the translation module drives the trolley frame 1 to shift towards one side of the track body 3, in order to ensure that the trolley frame 1 can move smoothly and avoid tilting caused by the change in the center of gravity of the measuring trolley during the translation process, in this embodiment, please refer to... Figures 6-8 Two sets of wedge plates 405 are symmetrically arranged on both sides of the bottom of the support plate 401. An inclined guide surface 406 is provided at the end of each wedge plate 405 that is close to the other. The inclined guide surface 406 corresponds to the arc-shaped portion 305 on the track body 3. The wedge plates 405 are connected to an elastic mechanism arranged on the support plate 401. The distance between the two wedge plates 405 is less than the width of the rail head 302 of the track body 3. It can be explained that as the adjusting unit drives the support plate 401 to move closer to the track body 3... The support plate 401 first synchronously drives the two wedge plates 405 to move. The inclined guide surface 406 of the wedge plate 405 first contacts the arc-shaped part 305. Under the limiting action of the arc-shaped part 305, the two wedge plates 405 can be driven to move away from each other. During the movement, the wedge plates 405 can compress the elastic mechanism and generate elastic force. When the support plate 401 contacts the surface of the rail head 302 on the track body 3, the two wedge plates 405 are just engaged in the right-angle slots 304 of the track body 3 (see reference). Figures 10-11 At this time, the upper surface of the wedge plate 405 is in contact with the lower surface of the rail head 302, which can achieve the effect of clamping and limiting. When the translation module drives the trolley frame 1 to shift away from the rail body 3, even if the center of gravity of the measuring trolley changes, it will not cause the phenomenon of tilting, thus ensuring that the trolley frame 1 moves smoothly.
[0066] It should also be noted that when the trolley frame 1 is offset to one side of the track body 3, the track wheel 101 of the trolley frame 1 is not in contact with the bearing plate 301. In this embodiment, the support plate 401 and the base 4 can be adjusted to move closer to each other through the adjustment part. Since the support plate 401 is limited by the wedge plate 405 and the rail head 302 at this time, the base 4 can only move closer to the support plate 401 by descending. During the descent of the base 4, the reinforcing beam 102 and the trolley frame 1 can be driven to descend simultaneously until the track wheel 101 contacts the bearing plate 301 and stops.
[0067] In this embodiment, the elastic mechanism includes a limiting plate 506 fixed on the wedge plate 405, and a guide rod 508 that is slidably inserted into the limiting plate 506 is correspondingly fixed on the support plate 401. A telescopic spring 509 is provided on the guide rod 508. One end of the telescopic spring 509 is fixed to the limiting plate 506, and the other end is fixed to the guide rod 508. It can be noted that the wedge plate 405 can slide synchronously on the guide rod 508 during the movement, thereby compressing the telescopic spring 509 and generating elastic force to drive the wedge plate 405 to reset.
[0068] As a further embodiment, when the trolley frame 1 is moved to one side of the track body 3, and when the drive base 4 is reset and moved to the bottom of the reinforcing crossbeam 102, in order to avoid interference caused by the wedge plate 405 engaging with the rail head 302, please refer to [reference needed]. Figures 6-8 An inclined guide plate 507 is fixedly arranged on the limiting plate 506. The two opposing inclined guide plates 507 are inclined in a direction away from each other. A limiting frame 407 is fixedly arranged on the bottom of the base 4. A guide wheel 408 corresponding to the inclined guide plate 507 is rotatably arranged on the bottom of the limiting frame 407. It can be explained that when the trolley frame 1 is moved to one side of the track body 3, as the adjusting part drives the base 4 to descend, the guide wheel 408 at the bottom of the base 4 first contacts the inclined guide plate 507. When the base 4 continues to descend, the guide wheel 408 can drive the inclined guide plate 507 to move away from the support plate 401. The inclined guide plate 507 drives the wedge plate 405 to move synchronously through the limiting plate 506. When the wedge plate 405 moves to a state where it is not engaged with the right angle slot 304, the track wheel 101 of the trolley frame 1 also contacts the bearing plate 301 at the same time (see reference). Figure 9 Correspondingly, at this time, the support plate 401 is not subject to the locking and limiting effect of the rail head 302, and can be driven by the adjustment part to move closer to the base 4 until the lower surface of the wedge plate 405 is flush with the upper surface of the rail head 302. Finally, the base 4 is driven by the translation module to reset and slide to the bottom of the reinforcing beam 102.
[0069] In another implementation, when the measuring trolley is located on the support plate 301, this embodiment first supports the trolley frame 1 by setting up a set of support frames. The base 4 is first moved to the two side rail bodies 3 by the translation module. The support plate 401 is lowered to contact the rail body 3 by the adjustment part. The wedge plate 405 is engaged with the rail head 302. Then the support frame is removed. The trolley frame 1 can be moved back to the base 4 by the translation module. The measuring trolley can then be moved to the rail body 3. The entire process does not require the use of a crane for hoisting and moving, which is more efficient.
[0070] An operating method for an intelligent measuring trolley used in rail transit includes the following steps:
[0071] Please see Figures 1-4 S1, the lifting module drives the base 4 to rise, and the base 4 drives the trolley frame 1 to rise to a certain height through the reinforcing beam 102, driving the track wheel 101 to separate from the track body 3.
[0072] S2. The translation module drives the reinforcing beam 102 to slide on the base 4. The reinforcing beam 102 synchronously drives the trolley frame 1 and the track wheel 101 to translate towards one side of the track body 3.
[0073] S3. After completely translating the trolley frame 1 and the track wheels 101 to one side of the track body 3, remove the base 4.
[0074] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
