Description

Technical Field

[0001] The present application relates to the field of rail transit technology, and in particular to an inspection vehicle. Background Art

[0002] In the related technology, inspection vehicles are often used for track maintenance or collision test inspection. When a rail train or a test trolley passes by the track, the inspection vehicle needs to be manually moved to a safe place in advance to prevent the rail train or test trolley from colliding with the inspection vehicle lying on the track.

[0003] Therefore, repeated handling leads to low working efficiency of the inspection vehicle, that is, low detection and marking efficiency. In addition, since the inspection vehicle needs to be manually moved away before the rail train or experimental trolley passes, it also threatens the life safety of the handling personnel and has a high risk factor. Summary of the invention

[0009] The first connecting rod assembly and the second connecting rod assembly are configured such that the first wheel group and the second wheel group are retracted between the first track and the second track when the main shaft is driven to rotate by the driving motor.

[0010] Preferably, the inspection vehicle further comprises:

[0011] A first support group and a second support group, wherein the first support group and the second support group are both located between the first track and the second track, the first support group is located on the side where the first track is located, and the second support group is located on the side where the second track is located;

[0012] Wherein, the first support group and the second support group both include downwardly extending legs, the first support group and the second support group are both connected to the main shaft transmission, and the first support group and the second support group are configured to shrink when the first connecting rod assembly and the second connecting rod assembly are retracted between the first track and the second track.

[0013] Preferably, the first track and the second track are mounted on sleepers, and the first support group and the second support group are configured so that when the first wheel group and the second wheel group are respectively overlapped on the first track and the second track, there is a gap between the lower end of the support leg and the sleeper.

[0014] Preferably, the inspection vehicle further comprises a vehicle body, the first support group and the second support group are connected to the vehicle body, and the first connecting rod assembly and the second connecting rod assembly are configured such that the first wheel group and the second wheel group are folded into the vehicle body.

[0016] Preferably, the first support group and the second support group are arranged opposite to each other, the main shaft passes between the first support group and the second support group, the inspection vehicle also includes a gear arranged on the main shaft and a gear arranged on the first support group and the second support group, and the main shaft is transmission-connected to the first support group and the second support group via the gear arranged on the main shaft and the gear arranged on the first support group and the second support group.

[0017] Preferably, the inspection vehicle further includes a vehicle body, the drive motor and the main shaft are arranged on the vehicle body, and the inspection vehicle further includes a battery, the battery is arranged on the vehicle body, and the battery is electrically connected to the drive motor to supply power to the drive motor.

[0018] Preferably, the inspection vehicle further includes a vehicle body, the first connecting rod assembly is hinged to the vehicle body, and the second connecting rod assembly is hinged to the vehicle body.

[0019] Preferably, a plurality of the first wheel sets are arranged on the side where the first track is located, and the second wheel sets are arranged in one-to-one correspondence with the first wheel sets.

[0026] After the first wheel group and the second wheel group are folded together, they can be lower than the rail surface of the first track and the second track (that is, the upper end surface of the first track and the second track), so there is no need to manually carry the inspection vehicle, because the inspection vehicle neither interferes with the vehicle on the track nor interferes with the bottom of the vehicle in height. In this way, after the inspection vehicle folds the first wheel group and the second wheel group, the inspection vehicle can be left between the first track and the second track without manual carrying. In this way, it is no longer necessary to manually carry the inspection vehicle repeatedly, which greatly improves efficiency and avoids manual repeated carrying of the inspection vehicle, which poses a threat to the lives of the carrying personnel.

[0027] Even if the height of the inspection vehicle with the first wheel group and the second wheel group is retracted and the track surface of the first track and the second track, since the inspection vehicle is already in the retracted state, even if manual transportation is required, the difficulty of manual transportation can be reduced, the time of manual transportation can be shortened, and the utilization efficiency of the inspection vehicle can be improved. In addition, since the time of manual transportation is reduced, the safety threat to the transportation personnel from vehicles passing on the track can also be reduced.

[0041] According to an embodiment of the present application, a patrol vehicle is provided. Figures 1 to 5 Describe in detail the structure and working principle of the inspection vehicle.

[0042] According to the inspection vehicle provided in the embodiment of the present application, the inspection vehicle is used to move on a first track and a second track 13 arranged side by side. The inspection vehicle includes a first wheel group 2, a second wheel group, a first connecting rod assembly 3, a second connecting rod assembly, a control mechanism 11, a drive motor 4 and a main shaft 6.

[0043] In the embodiment, the first wheel set 2 is used to overlap the first track, and the first wheel set 2 can roll along the first track, and the second wheel set is used to overlap the second track 13, and the second wheel set can roll along the second track 13. The first connecting rod assembly 3 is connected to the first wheel set 2, and the second connecting rod assembly is connected to the second wheel set.

[0044] In an embodiment, the drive motor 4 is transmission-connected to the main shaft 6, the main shaft 6 is transmission-connected to the first connecting rod assembly 3 and the second connecting rod assembly, the control mechanism 11 is communication-connected to the drive motor 4, and the control mechanism 11 is configured to receive a control signal to drive the motor 4 to rotate.

[0045] In the embodiment, the first link assembly 3 and the second link assembly are configured such that the first wheel set 2 and the second wheel set are retracted between the first rail and the second rail 13 when the main shaft 6 is driven to rotate by the driving motor 4 .

[0046] In this way, according to the inspection vehicle provided in the embodiment of the present application, when the inspection vehicle is required to operate on the first track and the second track 13, the first wheel group 2 and the second wheel group can roll along the first track and the second track 13 respectively, so that the inspection vehicle can move and operate across the first track and the second track 13.

[0047] When the inspection vehicle needs to avoid rail vehicles passing on the first track and the second track 13, a control signal can be sent to the control mechanism 11. After the control mechanism 11 receives the control signal, the drive motor 4 drives the main shaft 6 to rotate, and then drives the first connecting rod assembly 3 and the second connecting rod assembly, so that the first wheel group 2 and the second wheel group are retracted between the first track and the second track 13, thereby removing the first wheel group 2 and the second wheel group from the first track and the second track 13.

[0048] In this way, the inspection vehicle provided according to the embodiment of the present application can be remotely controlled to change its shape. After the inspection vehicle has changed its shape, the first wheel group 2 and the second wheel group have been removed from the first track and the second track 13, so that it will not interfere with the vehicles that will pass through the first track and the second track 13.

[0049] In an embodiment, the first wheel set 2 and the second wheel set can be lower than the rail surface of the first track and the second track 13 (that is, the upper end surface of the first track and the second track 13) after being folded, so that there is no need to manually carry the inspection vehicle, because the inspection vehicle neither interferes with the vehicle on the track nor interferes with the bottom of the vehicle in height. In this way, after the inspection vehicle folds the first wheel set 2 and the second wheel set, the inspection vehicle can be left between the first track and the second track 13 without manual transportation. In this way, it is no longer necessary to manually carry the inspection vehicle repeatedly, which greatly improves efficiency and avoids manual repeated transportation of the inspection vehicle, which poses a threat to the lives of the transporters.

[0050] In other examples, even if the height of the inspection vehicle with the first wheel group 2 and the second wheel group is folded up to the track surface of the first track and the second track 13, since the inspection vehicle is already in the folded state, even if manual transportation is required, the difficulty of manual transportation can be reduced, the time of manual transportation can be shortened, and the utilization efficiency of the inspection vehicle can be improved. In addition, since the time of manual transportation is reduced, the safety threat to the transporting personnel posed by vehicles passing on the track can also be reduced.

[0051] According to the inspection vehicle provided in the embodiment of the present application, a plurality of first wheel groups 2 are arranged on the side where the first track is located, and the second wheel groups are arranged one-to-one corresponding to the first wheel groups 2. As an example, two first wheel groups 2 can be arranged along the extension direction of the first track, and correspondingly, two first wheel groups 2 can be arranged correspondingly along the extension direction of the second track 13. For each first wheel group 2, the second wheel group can be arranged opposite to the first wheel group 2 in the extension direction perpendicular to the first track.

[0052] In the embodiment, the main shaft 6 can pass between the corresponding first wheel group 2 and the second wheel group, each first wheel group 2 is connected to the main shaft 6 through the first connecting rod assembly 3, and each second wheel assembly is connected to the main shaft 6 through the second connecting rod assembly. As the main shaft 6 is driven to rotate by the driving motor 4, the main shaft 6 will drive a series of first connecting rod assemblies 3 and second connecting rod assemblies connected to the main shaft 6, so that the first wheel group 2 and the second wheel group are retracted between the first track and the second track 13.

[0053] According to the inspection vehicle provided in the embodiment of the present application, the first wheel set 2 and the second wheel set may both include a wheel member and a wheel hub motor, and the wheel member may be configured to be able to roll. In the embodiment, the wheel hub motor may be connected to the wheel member, and the wheel hub motor drives the wheel member to rotate. In the embodiment, the wheel set is a whole integrated by the aforementioned wheel member and the wheel hub motor. In the embodiment, the wheel set may actually adopt an existing rail wheel with a wheel hub motor, and the wheel member may be formed with an annular wheel rim for forming a limit with the corresponding rail.

[0054] According to the inspection vehicle provided in the embodiment of the present application, the inspection vehicle may further include a first support group 7 and a second support group.

[0055] In an embodiment, the first support group 7 and the second support group may both be located between the first track and the second track 13 , the first support group 7 may be located on the side of the first track, and the second support group may be located on the side of the second track 13 .

[0056] In an embodiment, the first support group 7 and the second support group may both include a downwardly extending leg 8, the first support group 7 and the second support group may both be transmission-connected to the main shaft 6, and the first support group 7 and the second support group may be configured to shrink when the first connecting rod assembly 3 and the second connecting rod assembly are retracted between the first track and the second track 13.

[0057] In an embodiment, the legs 8 can support the inspection vehicle from below the inspection vehicle after the first wheel group 2 and the second wheel group leave the first track and the second track 13 respectively, so as to maintain the stability of the inspection vehicle.

[0058] In the embodiment, the first support group 7 and the second support group may include, for example, a screw box in the prior art, which may include an input end and an output end. In the embodiment, the input end of the screw box may be transmission-connected to the spindle 6, and the output end of the screw box may be used to connect the above-mentioned legs 8. As the input end of the screw box rotates, the output end rises and falls accordingly.

[0059] According to the inspection vehicle provided by the embodiment of the present application, the first track and the second track 13 are mounted on the sleepers 14, and the first support group 7 and the second support group are configured so that when the first wheel group 2 and the second wheel group are respectively overlapped on the first track and the second track 13, there is a gap between the lower end of the support leg 8 and the sleeper 14. In this way, when the inspection vehicle moves on the first track and the second track 13, the support leg 8 will not interfere with the movement of the inspection vehicle due to the gap between the support leg 8 and the sleeper 14.

[0060] According to the inspection vehicle provided in the embodiment of the present application, the inspection vehicle may further include a vehicle body 1, the first support group 7 and the second support group may be connected to the vehicle body 1, and the first connecting rod assembly 3 and the second connecting rod assembly may be configured so that the first wheel group 2 and the second wheel group are folded in the vehicle body 1. In this way, the inspection vehicle has a smaller volume after being folded in the vehicle body 1, which is convenient for placing the inspection vehicle between the first track and the second track 13, or for transport personnel to carry the inspection vehicle.

[0061] In addition, as described above, the first support group 7 and the second support group provided according to the embodiment of the present application are configured so that when the first wheel group 2 and the second wheel group are completely folded in the vehicle body 1, the common height of the vehicle body 1 and the support legs 8 is lower than the track surfaces of the first rail and the second rail 13, so that it is convenient to place the inspection vehicle between the first rail and the second rail 13.

[0062] As an example, taking the first connecting rod assembly 3 as an example, the first connecting rod assembly 3 may have a first connecting rod connected to the first wheel set 2, the first connecting rod may be hinged to the vehicle body 1, and the end thereof may be hinged to the second connecting rod of the first connecting rod assembly 3, and the second connecting rod may be transmission-connected to the main shaft 6. In an embodiment, the main shaft 6 may be connected to a cross bar 5, and one end of the cross bar 5 may be hinged to the second connecting rod. In an embodiment, the structure of the second connecting rod assembly may also be the same, and in addition, the second connecting rod of the second connecting rod assembly may be connected to the other end of the cross bar 5.

[0063] According to the inspection vehicle provided by the embodiment of the present application, the first support group 7 and the second support group are arranged opposite to each other, the main shaft 6 passes between the first support group 7 and the second support group, and the inspection vehicle also includes a gear arranged on the main shaft 6 and a gear arranged on the first support group 7 and the second support group, and the main shaft 6 is connected to the first support group 7 and the second support group via the gear arranged on the main shaft 6 and the gear arranged on the first support group 7 and the second support group. In the embodiment, a bevel gear 9 can be sleeved on the outside of the main shaft 6, and a driven shaft 10 can be arranged at the input end of the first support group 7 and the second support group. The bevel gear 9 that cooperates with the bevel gear 9 arranged on the outside of the main shaft 6 at the end of the driven shaft 10 drives the bevel gears 9 on the two driven shafts 10 to rotate through the rotation of the bevel gear 9 on the main shaft 6.

[0064] In addition, according to the inspection vehicle provided in the embodiment of the present application, the inspection vehicle may further include a battery 12 . The battery 12 may be disposed on the vehicle body 1 . The battery 12 is electrically connected to the drive motor 4 to supply power to the drive motor 4 .

[0065] like Figure 1 As shown, the embodiment of the present application essentially provides a self-powered track-use fast folding horizontal rail remote control inspection vehicle. The cross bar 5 connected to the main shaft 6 is driven by the driving motor 4, and the first connecting rod assembly 3 can fold the first wheel group 2. The front and rear two sets of driven shafts 10 rotate in the same direction, and the driven shaft 10 drives the first support group 7 to move and control the lifting of the legs 8. The energy source comes from the battery 12, and the control mechanism 11 can be interchanged according to different detection requirements.

[0066] like Figure 2 As shown, the width of the sleeper 14 is designed according to the second rail 13 and the diving depth of the second rail and the sleeper, so that there is a gap between the legs 8 even when the legs 8 are extended to the longest state.

[0067] like Figure 3 As shown, the first connecting rod assembly and the second connecting rod assembly can unfold the four sets of wheel components with hub motors and place them on the track plane. At this time, the lifting legs 8 are in an extended state, but the extended length is higher than the diving height of the sleepers 14, so that there is no interference when moving forward and backward.

[0068] like Figure 4 As shown, when the inspection vehicle is initially folded, the legs 8 fall onto the sleepers 14 while the first and second connecting rod assemblies are folded. The subsequent action is that the first and second connecting rod assemblies are folded at a large angle and retracted into the body of the inspection vehicle, and the lifting legs 8 are synchronously and slowly retracted.

[0069] like Figure 5As shown, since the first connecting rod assembly, the second connecting rod assembly, the first support group and the second support group are controlled by the same drive motor, the first connecting rod assembly and the second connecting rod assembly are folded and retracted into the body of the inspection vehicle, and the support legs 8 are completely retracted into the corresponding support groups. At this time, the inspection vehicle is in a retracted state, lying flat on the sleepers, and the upper surface of the vehicle body is far below the track plane.

[0070] The inspection vehicle provided in the embodiment of the present application aims to solve the problems of low efficiency in current rail transit maintenance or collision test detection and marking, high risk factor in manual operation, etc., and to provide a self-powered inspection vehicle that can be remotely controlled to run on a track, which can automatically telescope, fold and lie on the track. After telescoped and folded, the inspection vehicle as a whole can be below the track plane. When a rail train or a test trolley passes by the track, there is no need to manually move the inspection vehicle to a safe place in advance, and the rail train or test trolley will not collide with the inspection vehicle lying on the track when passing by.

[0071] This type of inspection vehicle improves the inspection or detection efficiency of the inspection vehicle, improves the work efficiency and safety of maintenance personnel, ensures that rail transit maintenance or experiments can operate stably and efficiently, and solves the problem that abnormal situations are often not handled in a timely manner and maintenance personnel need to be sent to relevant sections for inspection and maintenance after all trains are stopped.

[0072] The above are only preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. All equivalent structural changes made by using the contents of the present application specification and drawings under the innovative concept of the present application, or directly / indirectly applied in other related technical fields are included in the protection scope of the present application.
