Description

Technical Field

[0001] The present invention relates to the technical field of rail transportation, and in particular to an intelligent measuring vehicle for rail transportation. Background Art

[0002] The rail transit measurement trolley is a device specially used for various measurement work in the rail transit field. It is widely used in the construction, maintenance and inspection of rail transit such as subways, light rails, and railways. It has high measurement accuracy and efficiency, can quickly obtain a large amount of track data, and reduce the error and workload of manual measurement.

[0003] Since the inner side of the rail wheel is provided with a rim (25-30mm higher than the tread), when the trolley enters a curve, the rim contacts the side of the rail body, so as 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, based on the setting of the rim, the structure formed by the engagement with the track cannot be removed by horizontal movement. Usually, it is necessary to use a crane to lift the rail transit intelligent measuring trolley to a certain height and then move it horizontally, or to manually disassemble the measuring trolley in advance and then remove it. The operation process of these two methods is relatively cumbersome and inconvenient to use. Summary of the Invention

[0004] The purpose of the present invention is to provide an intelligent measuring vehicle for rail transit to solve the following technical problems: The moving process of the intelligent measuring vehicle in the prior art is relatively complicated.

[0005] The purpose of the present invention can be achieved through the following technical solutions: An intelligent measuring trolley for rail transportation, comprising a trolley frame, wherein the trolley frame is provided with four sets of rail wheels for moving on a rail body; A reinforcing crossbeam is fixedly arranged at the bottom of the trolley frame, and the reinforcing crossbeam is slidably arranged on the base; Among them, the base is provided with a translation module, and the track body module is used to drive the reinforcement beam to slide on the base; the base is also provided with a lifting module, and the lifting module is used to drive the base to rise and fall.

[0006] Preferably, a plurality of measuring sensors are arranged on both the front and rear sides of the trolley frame, and each measuring sensor is electrically connected to a server fixedly arranged on the trolley frame.

[0007] Preferably, two groups of T-shaped sliding grooves are symmetrically provided on the base, and a T-shaped slide seat slidably connected to the T-shaped sliding grooves is fixedly arranged on the bottom of the reinforcing beam.

[0008] Preferably, the translation module includes racks symmetrically fixed on both sides of the base; Wherein, translation motors are fixedly arranged on both sides of the reinforcing crossbeam, and a gear meshing with the rack is fixedly arranged on the driving end of the translation motor.

[0009] Preferably, a bearing plate is provided on one side of the track body.

[0010] Preferably, two groups of support plates are symmetrically arranged below the base, and the positions of the two groups of support plates correspond to the positions of the track bodies on both sides; Wherein, the base is provided with an adjusting portion, which is used to drive the support plate and the base to move closer to each other or away from each other.

[0011] Preferably, the adjustment part includes a bidirectional screw 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 to the base, a nut is symmetrically spirally sleeved on the bidirectional screw, the bottom of the nut is hinged with a push rod, and the other end of the push rod is hinged to one side of the support plate; Wherein, a telescopic rod is fixedly arranged on the support plate, and the other end of the telescopic rod is plugged into a sleeve fixed to the bottom of the base.

[0012] Preferably, two groups of wedge-shaped plates are symmetrically arranged on both sides of the bottom of the support plate, and an inclined guide surface is provided at one end of the wedge-shaped plates that is close to each other, and the inclined guide surface corresponds to the arc-shaped portion on the track body, and the wedge plates are connected to the elastic mechanism arranged on the support plate; Wherein, the distance between the wedge plates on both sides is smaller than the width of the rail head of the rail body.

[0013] Preferably, the elastic mechanism includes a limiting plate fixed on the wedge plate, a guide rod slidably plugged with the limiting plate is fixedly arranged on the support plate, and a telescopic spring is provided on the guide rod.

[0014] Preferably, an inclined guide plate is fixedly arranged on the limit plate, and the inclined guide plates on two opposite sides are inclined in directions away from each other; Wherein, a limiting frame is fixedly arranged at the bottom of the base, and a guide wheel corresponding to the inclined guide plate is rotatably arranged at the bottom of the limiting frame.

[0015] A method for operating an intelligent measuring vehicle for rail transit comprises the following steps: The lifting module drives the base to rise, and the base drives the trolley frame to rise to a certain height through the reinforced crossbeam, driving the rail wheels to separate from the rail body; The translation module drives the reinforcement beam to slide on the base, and the reinforcement beam synchronously drives the trolley frame and the rail wheel to translate toward one side of the rail body; After the trolley frame and rail wheels are completely moved to one side of the rail body, the base is removed.

[0016] Beneficial effects of the present invention: (1) The present invention drives the base to rise by the lifting module, and the base can drive the trolley frame to rise to a certain height through the reinforcing beam, thereby driving the rail wheel to separate from the rail body. Secondly, the reinforcing beam is driven to slide on the base by the translation module, and the reinforcing beam synchronously drives the trolley frame and the rail wheel to translate toward one side of the rail body. After the trolley frame and the rail wheel are completely translated to one side of the rail body, the base can be removed. The present invention does not require the use of crane equipment to lift and remove the measuring trolley, nor does it require the disassembly and removal of the measuring trolley. The effect of automatic removal can be achieved, which is more efficient. (2) In the present invention, after the measuring trolley moves to one side of the track body, the measuring trolley is positioned, and the gear can be driven by the translation motor to rotate in the opposite direction. During the rotation of the gear, the base can be driven to slide at the bottom of the reinforcing beam to move the base back to the bottom of the reinforcing beam. The present invention does not require manual removal of the base, and has a higher degree of automation; (3) In the present invention, as the adjustment part drives the support plate to move in the direction close to the rail body, the support plate first drives the wedge plates on both sides to move synchronously, and the inclined guide surface of the wedge plates first contacts the arc part. Under the limiting action of the arc part, the wedge plates on both sides can be driven to move away from each other. The wedge plates can compress the elastic mechanism and generate elastic force during the movement. When the support plate contacts the surface of the rail head on the rail body, the wedge plates on both sides are just clamped in the right-angle clamping groove of the rail body. At this time, the upper surface of the wedge plate fits with the lower surface of the rail head, which can play a clamping and limiting effect. When the translation module drives the trolley frame to deviate in the direction away from the rail body, even if the center of gravity of the measuring trolley changes, it will not cause the tilting phenomenon, ensuring the smooth translation of the trolley frame. (4) In the present invention, when the measuring trolley is located on the load-bearing plate, the trolley frame is first supported by setting up a set of support frames. The base can be first driven to move to the rail bodies on both sides by the translation module, and the support plate is driven down to contact the rail body by the adjustment part, and the wedge plate is connected to the rail head. Then, the support frame is removed, and the trolley frame can be translated to the base again by the translation module, and the measuring trolley can be moved to the rail body. No crane equipment is required for lifting and moving during the whole process, which is more efficient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The specific embodiments of the present invention are described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0021] Example 1 See also Figure 1-Figure 3As shown, the present invention is an intelligent measuring trolley for rail transportation, including a trolley frame 1, on which are provided four sets of rail wheels 101 for moving on a rail body 3; specifically, the intelligent vehicle trolley of this embodiment adopts an electric drive method to drive the rail wheels 101 to rotate on the rail body 3, wherein 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 rail body 3 of the rail vehicle during normal driving during movement, thereby achieving the effect of precise measurement.

[0022] In this embodiment, a plurality of measuring sensors 201 are arranged on both the front and rear sides of the trolley frame 1, and each measuring sensor 201 is electrically connected to the server 2 fixedly arranged on the trolley frame 1; specifically, the measuring sensors 201 in this embodiment can be: Gauge sensor: uses laser or inductive sensors to measure gauge changes in real time; Level / superelevation sensor: uses a gyroscope or inclinometer to detect the lateral inclination of the track and the superelevation value of the curved section.

[0023] In addition, a mileage encoder is provided on the rail wheel 101 to record the mileage of the trolley (with an accuracy of ±5mm); It should be noted that each measurement sensor 201 uploads data to the server 2 via a wireless communication module (such as 4G / 5G), and generates a track health report in conjunction with the GIS system.

[0024] In this embodiment, please refer to Figure 3-Figure 5 A reinforcing beam 102 is fixedly arranged at the bottom of the trolley frame 1, and the reinforcing beam 102 is slidably arranged on the base 4; wherein, a translation module is provided on the base 4, and the track body 3 module is used to drive the reinforcing beam 102 to slide on the base 4; Furthermore, a lifting module is provided on the base 4, and the lifting module is used to drive the base 4 to rise and fall; 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, and the base 4 can drive the trolley frame 1 to rise to a certain height through the reinforcing beam 102, and then drive the rail wheel 101 to separate from the track body 3, and then the reinforcing beam 102 is driven to slide on the base 4 by the translation module, and the reinforcing beam 102 synchronously drives the trolley frame 1 and the rail wheel 101 to translate toward one side of the track body 3. After the trolley frame 1 and the rail wheel 101 are completely translated to one side of the track body 3, the base 4 can be removed. This embodiment does not require the use of crane equipment to lift and remove the measuring trolley, nor does it require the measuring trolley to be disassembled and removed. It can achieve the effect of automatic removal, which is more efficient.

[0025] Example 2 On the basis of embodiment 1, in order to improve the stability of the sliding of the reinforcement beam 102 on the base 4, please refer to Figure 3-Figure 4 Two groups of T-shaped slide grooves 409 are symmetrically provided on the base 4, and a T-shaped slide 103 slidably connected to the T-shaped slide grooves 409 is fixed at the bottom of the reinforcing beam 102; it can be explained that this embodiment slidingly connects the base 4 and the reinforcing beam 102 by setting the T-shaped slide grooves 409 and the T-shaped slide 103. On the one hand, it can improve the stability of the horizontal sliding of the reinforcing beam 102 on the base 4 and achieve the guiding effect. On the other hand, it can enable the base 4 and the reinforcing beam 102 to move synchronously on the rail body 3. When the rail 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.

[0026] In this embodiment, please refer to Figure 5-Figure 8 The translation module includes racks 402 symmetrically fixed on both sides of the base 4, wherein translation motors 403 are fixedly arranged on both sides of the reinforcing beam 102, and the driving end of the translation motor 403 is fixedly provided with a gear 404 engaged with the rack 402; it can be explained that when driving the reinforcing beam 102 to move on the base 4, the translation motor 403 is started to drive the gear 404 to rotate, and the gear 404 can drive the reinforcing beam 102 to slide on the base 4 by engaging with the rack 402 during the rotation process, so as to synchronously drive the trolley frame 1 to move.

[0027] Correspondingly, when the measuring trolley moves to one side of the track body 3, the measuring trolley is positioned. In this embodiment, the gear 404 can be driven to rotate in the opposite direction by the translation motor 403. During the rotation, the gear 404 can drive the base 4 to slide at the bottom of the reinforcing beam 102 to move the base 4 back to the bottom of the reinforcing beam 102. In this embodiment, there is no need to manually remove the base 4, and the degree of automation is higher.

[0028] As a further solution of this embodiment, please refer to Figure 1-Figure 2 A bearing plate 301 can be provided on one side of the track body 3 to support the measuring trolley after it is removed.

[0029] See also Figure 5-Figure 8Two groups of support plates 401 are symmetrically arranged under the base 4, and the positions of the two groups of support plates 401 correspond to the positions of the track bodies 3 on both sides, wherein an adjusting portion is provided on the base 4, which is used to drive the support plates 401 and the base 4 to move closer to or away from each other; it can be explained that in the initial state, the rail 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 in a separated state 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 descend through the adjusting portion, and the support plates 401 first contact the track body 3, and then the support plates 401 and the base 4 are driven away from each other again through the adjusting portion. 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.

[0030] The two ends of the two-way screw 501 are fixed to the output end of the lifting motor 5 fixed to the base 4, and the two-way screw 501 is symmetrically spirally sleeved with a nut 502. The bottom of the nut 502 is hinged with a push rod 503, and the other end of the push rod 503 is hinged to one side of the support plate 401. A telescopic rod 505 is fixed on the support plate 401, and the other end of the telescopic rod 505 is plugged into a sleeve 504 fixed to the bottom of the base 4. It can be explained that when the support plate 401 is driven to rise and fall, the two-way screw 501 is driven to rotate by the lifting motor 5 in this embodiment. During the movement of the nuts 502 on both sides on the two-way 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 lifting effect.

[0031] See also Figure 10 As the existing technology in this field, the rail body 3 includes a rail head 302 and a rail waist 303. The rail head 302 is fixed on the rail waist 303, and the two form a T-shaped structure. A right-angle slot 304 is formed between the rail head 302 and the rail waist 303, wherein arc-shaped portions 305 are respectively provided on both sides of the rail head 302; specifically, the rail head 302 contacts the wheel and withstands the rolling pressure of the wheel; the rail waist 303 connects the rail head 302 and the rail bottom to enhance the overall strength of the rail; the rail body 3 in this embodiment is a rail structure in the existing technology, which will not be described in detail in this embodiment.

[0032] Furthermore, when the translation module drives the trolley frame 1 to deviate toward one side of the track body 3, in order to ensure that the trolley frame 1 can move smoothly and avoid the phenomenon of tilting caused by the change of the center of gravity of the measuring trolley during the translation process, in this embodiment, you can refer to Figure 6-Figure 8, two groups of wedge plates 405 are symmetrically arranged on both sides of the bottom of the support plate 401, and an inclined guide surface 406 is provided at one end of the wedge plates 405 that is close to each other. The inclined guide surface 406 corresponds to the arc portion 305 on the track body 3, and the wedge plates 405 are connected to the elastic mechanism arranged on the support plate 401, wherein the distance between the wedge plates 405 on both sides is less than the width of the rail head 302 of the track body 3; It can be explained that as the adjustment part drives the support plate 401 to move in the direction close to the track body 3 The support plate 401 first drives the wedge plates 405 on both sides to move synchronously. The inclined guide surface 406 of the wedge plates 405 first contacts the arc portion 305. Under the limiting action of the arc portion 305, the wedge plates 405 on both sides can be driven to move away from each other. The wedge plates 405 can compress the elastic mechanism and generate elastic force during the movement. When the support plate 401 contacts the surface of the rail head 302 on the rail body 3, the wedge plates 405 on both sides are just clamped in the right-angled grooves 304 of the rail body 3 (see Figure 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 play a clamping and limiting effect. When the translation module drives the trolley frame 1 to deviate in the direction away from the rail body 3, even if the center of gravity of the measuring trolley changes, it will not cause the tilting phenomenon, ensuring that the trolley frame 1 can translate smoothly.

[0033] It should also be noted that when the trolley frame 1 is offset to one side of the rail body 3, the rail wheel 101 of the trolley frame 1 is not in contact with the load-bearing plate 301. In this embodiment, the support plate 401 and the base 4 can be adjusted to be 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 approach the support plate 401 by descending. During the descent of the base 4, the reinforcing beam 102 and the trolley frame 1 can be synchronously driven to descend until the rail wheel 101 contacts the load-bearing plate 301 and stops.

[0034] In this embodiment, the elastic mechanism includes a limit plate 506 fixed on the wedge plate 405, and a guide rod 508 is correspondingly fixed on the support plate 401 and slidably plugged with the limit plate 506. A telescopic spring 509 is provided on the guide rod 508, and one end of the telescopic spring 509 is fixed to the limit plate 506, and the other end is fixed to the guide rod 508; it can be explained 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.

[0035] As a further solution of this embodiment, when the trolley frame 1 is translated to the side of the rail body 3, when the driving base 4 is reset and translated to the bottom of the reinforcing beam 102, in order to avoid the wedge plate 405 and the rail head 302 from interfering with each other, please refer to Figure 6-Figure 8, an inclined guide plate 507 is fixedly arranged on the limit plate 506, and the inclined guide plates 507 on the opposite sides are inclined in the direction of moving away from each other, wherein a limiting frame 407 is fixedly arranged on the bottom of the base 4, and a guide wheel 408 corresponding to the inclined guide plate 507 is rotatably arranged at the bottom of the limiting frame 407; it can be explained that when the trolley frame 1 is translated to one side of the track body 3, as the adjustment 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. As the base 4 continues to descend, the guide wheel 408 can drive the inclined guide plate 507 to move in the direction away from the support plate 401, and 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 non-engaged state with the right-angle slot 304, the rail wheel 101 of the trolley frame 1 also contacts the bearing plate 301 at the same time (see Figure 9 ), accordingly, the support plate 401 at this time is not affected by the clamping and limiting effect of the rail head 302, and the support plate 401 can be driven toward the base 4 by the adjustment part until the lower surface of the wedge plate 405 is flush with the upper surface of the rail head 302, and finally the base 4 is driven to reset and slide to the bottom of the reinforcing beam 102 through the translation module.

[0036] As another embodiment, when the measuring trolley is located on the load-bearing plate 301, this embodiment first supports the trolley frame 1 by setting up a group of support frames, and can first drive the base 4 to move to the rail bodies 3 on both sides through the translation module, and then drive the support plate 401 down to contact with the rail body 3 through the adjustment part, and the wedge plate 405 is connected with the rail head 302. Then, the support frame is removed, and the trolley frame 1 can be translated to the base 4 through the translation module, and the measuring trolley can be moved to the rail body 3. No crane equipment is required for lifting and moving throughout the process, which is more efficient.

[0037] A method for operating an intelligent measuring vehicle for rail transit comprises the following steps: See also Figure 1-Figure 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 rail wheel 101 to separate from the rail body 3; S2, the translation module drives the reinforcing beam 102 to slide on the base 4, and the reinforcing beam 102 synchronously drives the trolley frame 1 and the rail wheel 101 to translate toward one side of the rail body 3; S3. After the trolley frame 1 and the rail wheel 101 are completely translated to one side of the rail body 3, the base 4 is removed.

[0038] The above disclosures are only a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
