Detailed implementation manners

[0037] In order to make the technical solutions and advantages in the embodiments of the present application clearer and more understandable, the following further elaborates on the exemplary embodiments of the present application with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than an exhaustive list of all embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0038] According to the first aspect of the embodiments of the present application, Figure 1 is the structural schematic of the vehicle body provided by the embodiment of the present application, in which the guiding device 100 in the lifted state is schematically shown with a dashed line, Figure 2 is the front view schematic of the guiding device 100 provided by the embodiment of the present application, Figure 6 is the side view schematic of the guiding device 100 provided by the embodiment of the present application, as Figure 1, Figure 2 and Figure 6 As shown, a guiding device 100 is provided for cooperating with a rail 1 to guide a vehicle. The guiding device 100 includes a guiding wheel assembly, a lifting mechanism, and a linkage mechanism. The guiding wheel assembly includes a pair of guiding wheels 11 for cooperating with the rail 1 and an axle 12 connected between the pair of guiding wheels 11. The pair of guiding wheels 11 are configured to travel along the pair of rails 1. The lifting mechanism includes a lifting driving member 20 and a first movable hinge assembly 80. The lifting driving member 20 includes a lifting driving body 23 and a telescopic member 21. The telescopic member 21 is telescopically inserted into the lifting driving body 23 (such as a cylinder). The top end portion 22 of the lifting driving body 23 is hinged to the vehicle frame 201 through the first movable hinge assembly 80, so that the lifting driving member 20 has at least a degree of freedom of moving in the width direction of the vehicle frame 201 and a degree of freedom of rotating about the hinge point between the first movable hinge assembly 80 and the vehicle frame 201.

[0039] The linkage mechanism includes a second movable hinge assembly 90 and a connecting rod 31. The connecting rod 31 includes a first end portion 311, a second end portion 312, and a hinge portion 313 located between the first end portion 311 and the second end portion 312. The hinge portion 313 is hinged to the telescopic member 21. The first end portion 311 is connected to the axle 12. The second end portion 312 is movably hinged to the vehicle frame 201 through the second movable hinge assembly 90, so that the connecting rod 31 together with the axle 12 has at least a degree of freedom of moving in the width direction of the vehicle frame 201 and a degree of freedom of rotating about the hinge point between the second movable hinge assembly 90 and the vehicle frame 201.

[0040] The "degree of freedom of moving in the width direction of the vehicle frame 201" can refer to the ability to move along the width direction of the vehicle frame 201 or the ability to swing in the width direction of the vehicle frame 201. "Movable hinge" is different from ordinary hinge. Through the structure of movable hinge, it can not only rotate about the hinge axis, but also has other degrees of freedom, such as the degree of freedom of moving in the width direction of the vehicle frame 201.

[0041] In the above technical solution, since the second end portion 312 and the hinge portion 313 of the connecting rod 31 are respectively hinged to the vehicle frame 201 and the telescopic member 21, when it is necessary to lower the guide wheel 11 to cooperate with the rail 1, the guiding device 100 is in the guiding state, and the telescopic member 21 of the lifting driving member 20 extends downward, thereby driving the connecting rod 31 to rotate downward around the hinge with the vehicle frame 201, driving the guide wheel 11 fixed to the first end portion 311 of the connecting rod 31 to descend until the guide wheel 11 descends to a preset position and abuts against the rail 1, so as to guide the vehicle traveling on the rail 1; when the guide wheel 11 is not needed, the guiding device 100 is in the lifting state, and the telescopic member 21 of the lifting driving member 20 retracts upward, thereby driving the connecting rod 31 to rotate upward around the hinge with the vehicle frame 201, driving the guide wheel 11 fixed to the first end portion 311 of the connecting rod 31 to rise to a preset position and separate from the rail 1. Therefore, through the above guiding device 100, the lifting and lowering of the guide wheel 11 can be conveniently realized, with the advantages of simple and compact structure, convenient guiding of the rail 1, low manufacturing cost, convenient maintenance, etc., improving the operation efficiency and quality on site and saving costs.

[0042] Moreover, since the top end portion 22 of the lifting driving member 20 (i.e., the top end portion of the lifting driving body 23) is movably hinged to the vehicle frame 201 through the first movable hinge assembly 80, and the second end portion 312 of the connecting rod 31 is movably hinged to the vehicle frame 201 through the second movable hinge assembly 90, the lifting driving member 20 and the connecting rod 31 can move or swing in the width direction of the vehicle frame 201, and further the guide wheel 11 connected to the first end portion 311 of the connecting rod 31 can move or swing in the width direction of the vehicle frame 201. When the vehicle passes through the curve of the rail 1, the guide wheel 11 can adaptively move or swing along with the curve of the rail 1, and always keep in close contact with the surface of the rail 1, so as to provide good guiding for the vehicle traveling to the curve of the rail 1.

[0043] In an embodiment of the present application, the first movable hinge assembly 80 and the second movable hinge assembly 90 have the same structural composition.

[0044] In the present application, there is no limitation on how the movable hinge assembly (the first movable hinge assembly 80, the second movable hinge assembly 90) specifically realizes the freedom of movement in the width direction of the vehicle frame 201 and the freedom of rotation around the hinge. For example, the movable hinge assembly can be a universal joint, and the top end of the cylinder barrel is connected to the vehicle frame 201 through the universal joint, so that the lifting mechanism can not only rotate around the hinge, but also swing in the width direction of the vehicle frame 201, having the freedom of movement in the width direction of the vehicle frame 201. Similarly, the second end portion 312 of the connecting rod 31 can also be connected to the vehicle frame 201 through the universal joint.

[0045] In an embodiment of the present application Figure 3 ForFigure 2 Partial enlarged schematic view at position A in Figure 4 is Figure 2 Partial enlarged schematic view at position B in Figure 3 , Figure 4 and Figure 6 As shown in , the guiding device 100 further includes a first ear group 13 for fixing to the vehicle frame 201. The first ear group 13 includes a pair of oppositely arranged ears 131, and each ear 131 is provided with a fixing hole. The first movable hinge assembly 80 includes a first rotating shaft 81 extending in the width direction of the vehicle frame 201. The top end portion 22 of the cylinder barrel is located between the pair of ears 131. The top end portion 22 of the cylinder barrel is provided with a first shaft hole, and the first rotating shaft 81 passes through the two fixing holes and the first shaft hole. The first rotating shaft 81 has a clearance fit with the first shaft hole, so that the top end portion 22 can rotate around the first rotating shaft 81. There is a movable clearance between the top end portion 22 of the cylinder barrel and the pair of ears 131 in the axial direction of the first rotating shaft 81, so that the lifting driving member 20 has the freedom to move in the width direction of the vehicle frame 201. In other words, the lifting driving member 20 can move or swing in the width direction of the vehicle frame 201. Optionally, the first movable hinge assembly 80 and the second movable hinge assembly 90 have the same structural composition. The second movable hinge assembly 90 is hinged to a second ear group 14 on the vehicle frame 201. There is also a movable clearance between the second end portion 312 of the connecting rod 31 and the ear 131 of the second ear group 14 in the axial direction.

[0046] Due to the above-mentioned movable clearance being provided, when the vehicle passes through a curve of the track, the connecting rod 31 and the lifting driving member 20 can move or swing adaptively in the width direction of the vehicle frame 201, so as to ensure that the guiding wheel 11 is in close contact with the surface of the steel rail 1, and prevent the guiding wheel 11 from separating from the steel rail 1 when passing through the curve and losing the guiding function of the vehicle.

[0047] In an embodiment of the present application, as shown in Figure 3 and Figure 4 The first movable hinge assembly 80 further includes at least two elastic pads 82. The top end portion 22 includes a first plane opposite to one of the ears 131 and a second plane opposite to the other ear 131. The surface of the top end portion 22 facing the ear 131 is flattened to form a plane. The first shaft hole extends from the first plane to the second plane and penetrates the top end portion 22. Elastic pads 82 are arranged in the movable clearance, the first rotating shaft 81 passes through the elastic pads 82, at least one elastic pad 82 is clamped between the first plane and the corresponding ear 131, and at least one elastic pad 82 is clamped between the second plane and the corresponding ear 131. The first movable hinge assembly 80 and the second movable hinge assembly 90 have the same structural composition, and the second movable hinge assembly 90 also includes at least two elastic pads 82. Elastic pads 82 are also arranged on both lateral sides of the second end portion 312 of the connecting rod 31.

[0048] Since the elastic pad 82 is provided in the movable gap, when the vehicle passes through the curve of the rail 1, the top end 22 of the lifting drive member 20 will squeeze the elastic pad 82 on the corresponding side, and the second end 312 of the connecting rod 31 will also squeeze the elastic pad 82 between the lugs 131 in the second lug group 14, so that the guide wheel 11 can have a certain degree of freedom in the width direction of the frame 201, and the elastic pad 82 can prevent the top end 22 of the lifting drive member 20 from colliding with the lug 131 when moving laterally, thereby reducing abnormal noise and wear.

[0049] Optionally, the elastic pad 82 may be a rubber pad or a silicone pad or other material that can be compressed and has a certain elasticity.

[0050] In one embodiment of the present application, Figure 3 and Figure 4 As shown, the first movable hinge assembly 80 also includes a swing bearing 83, which is disposed between a pair of lugs 131, the inner ring of the swing bearing 83 is sleeved on the first rotating shaft 81, and the top end 22 is sleeved on the outer ring through the first shaft hole. The first movable hinge assembly 80 and the second movable hinge assembly 90 have the same structure, and the second movable hinge assembly 90 also includes a swing bearing 83. Optionally, the swing bearing 83 can be a joint bearing.

[0051] By providing the swing bearing 83 , the lifting drive member 20 can be allowed to rotate around the first rotating shaft 81 and can also be allowed to swing left and right in the axial direction.

[0052] In one embodiment of the present application, Figure 3 As shown, the first movable hinge assembly 80 also includes two sleeves 84, a first end cover 85, a second end cover 86 and a first oil groove 87. The two sleeves 84 are respectively sleeved on the first rotating shaft 81, and the first end portions 311 of the two sleeves 84 are respectively against the two sides of the swing bearing 83, thereby limiting the displacement of the swing bearing 83 in the axial direction. The sleeves 84 are respectively passed through the fixing holes on the support ears 131. The outer wall of the sleeve 84 cooperates with the fixing hole, and the inner wall of the sleeve 84 cooperates with the first rotating shaft 81. The first end cover 85 and the second end cover 86 are respectively against the side walls of a pair of support ears 131 away from the top end portion 22, and cover the fixing holes on the support ears 131. The first end cover 85 and the second end cover 86 are used to limit the movement of the first rotating shaft 81 in the axial direction. The first rotating shaft 81 is provided with a connecting hole extending in the axial direction and a radial hole extending in the radial direction. The first end cover 85 is provided with a first through hole corresponding to the connecting hole. Both ends of the connecting hole are respectively connected to the first through hole and the radial hole to form a first oil groove 87 for supplying oil to the swing bearing 83.

[0053] A second through hole corresponding to the first rotating shaft 81 is formed in the second end cover 86. The first rotating shaft 81 is provided with a shaft end connection section 811 that passes through the second through hole and is exposed outside the second end cover 86. The shaft end connection section 811 is provided with an external thread, and the nut member 88 is engaged with the shaft end connection section 811.

[0054] Therefore, by providing the first end cover 85 and the second end cover 86, the movement of the first rotating shaft 81 in the axial direction can be restricted, and the first rotating shaft 81 is limited between a pair of ear members 131 in the first ear member group 13.

[0055] In this application, there is no limitation on the specific type of the lifting driving member 20. For example, it can be a pneumatic cylinder, and the telescopic member 21 is driven to expand and contract by the compressed air generated by a gas pump.

[0056] In an embodiment of this application, the lifting driving member 20 is a hydraulic cylinder, and the telescopic member 21 is driven to expand and contract by the hydraulic oil generated by a hydraulic pump. The hydraulic cylinder can be powered by an external hydraulic pump station through a hydraulic oil pipe, and the lifting and lowering of the guide wheel 11 can be realized.

[0057] In order to be able to drive the guide wheel 11 to lift and lower, in an embodiment of this application, as Figure 2 and Figure 6 shown, the telescopic member 21 includes a telescopic rod 211 and a guide post 212. Optionally, the bottom end of the telescopic rod 211 is threadedly connected to the top end of the guide post 212. The lifting driving main body 23 is a cylinder barrel. The top end of the telescopic rod 211 is slidably engaged with the cylinder barrel along the length direction of the telescopic rod 211. The bottom end of the telescopic rod 211 is connected with a guide post 212. The link mechanism further includes a hinge assembly, and the guide post 212 is hinged to the hinge portion 313 through the hinge assembly.

[0058] Optionally, as Figure 5 shown, the hinge assembly includes a second rotating shaft 32 and a connecting seat 33. A first hinge hole extending in the width direction of the vehicle frame 201 is formed in the hinge portion 313. The connecting seat 33 is sleeved on the guide post 212. A second hinge hole extending in the width direction of the vehicle frame 201 is formed in the connecting seat 33. The second rotating shaft 32 passes through the first hinge hole and the second hinge hole, and the second rotating shaft 32 is in clearance fit with the second hinge hole, so that when the guide wheel 11 lifts and lowers, the lifting driving member 20 and the link 31 can rotate around the second rotating shaft 32 respectively.

[0059] In an embodiment of this application, as Figure 5As shown, the hinge assembly also includes a connecting sleeve 34 and a first sleeve 35. Optionally, the connecting rod 31 is a hollow structure. The connecting sleeve 34 extends in the width direction of the frame 201, and the connecting sleeve 34 is inserted into the first hinge hole and fixedly connected to the hinge portion 313. The first sleeve 35 is inserted into the second hinge hole, and the second rotating shaft 32 passes through the center hole of the connecting sleeve 34 and is inserted into the center hole of the first sleeve 35. The second rotating shaft 32 is loosely matched with the center hole of the first sleeve 35. By providing the connecting sleeve 34, the matching length with the second rotating shaft 32 in the axial direction can be increased, which is convenient for the connecting rod 31 to rotate around the second rotating shaft 32, and the second rotating shaft 32 is prevented from directly contacting the hinge portion 313, thereby reducing wear. By providing the first sleeve 35, the guide column 212 is convenient for rotating around the second rotating shaft 32, and the second rotating shaft 32 is prevented from directly contacting the connecting seat 33, thereby reducing wear.

[0060] Furthermore, the end of the second rotating shaft 32 inserted into the central hole of the first sleeve 35 is a fitting section, and an oil groove 36 is also provided around the outer circumference of the fitting section, and the oil groove 36 is communicated with the gap between the second rotating shaft 32 and the first sleeve 35. By providing the oil groove 36 in the fitting section, the lubricating liquid can be spread between the fitting section and the first sleeve 35, thereby reducing the friction between the two.

[0061] Optionally, the hinge assembly further includes a third end cover 51. The third end cover 51 is connected to the end surface of the connecting sleeve 34 on the side away from the connecting seat 33, so that the third end cover 51 can cover the end surface of the connecting sleeve 34, thereby limiting the axial movement of the second rotating shaft 32. One end of the second slot is connected to the third end cover 51, and the other end is inserted into the second rotating shaft 32 and connected to the second rotating shaft 32. The second rotating shaft 32 is provided with an axial oil hole extending in the axial direction, and the third end cover 51 is provided with an end cover oil hole connected to the axial oil hole, and the axial oil hole and the end cover oil hole together form a second oil groove 52 for supplying oil to the oil groove 36.

[0062] In order to connect the connecting rod 31 to the axle 12 and increase the connection between the lifting mechanism and the axle 12, in one embodiment of the present application, as shown in FIG. Figure 5 As shown, the connection seat 33 includes a first connection portion 331 and a second connection portion 332. The first connection portion 331 is arranged between the guide column 212 and the hinge portion 313, and the second hinge hole is opened on the first connection portion 331. The second connection portion 332 is arranged on the side of the guide column 212 away from the hinge portion 313, and the second connection portion 332 is provided with a third hinge hole extending in the width direction of the frame 201. Optionally, the first hinge hole and the second hinge hole are coaxially arranged.

[0063] The hinge assembly further includes a connecting plate 37 and a third rotating shaft 38, one end of the third rotating shaft 38 is inserted into the third hinge hole and is clearance-matched with the third hinge hole, and the other end is passed through the connecting plate 37. The bottom end of the connecting plate 37 is sleeved on the axle 12 and fixedly connected to the axle 12.

[0064] Therefore, the guide column 212 is hinged to the axle 12 through the third rotating shaft 38 and the connecting plate 37 . When the guide wheel 11 is raised or lowered, the guide column 212 can rotate relative to the axle 12 . Specifically, the guide column 212 rotates around the third rotating shaft 38 relative to the connecting plate 37 .

[0065] Optionally, an oil groove 36 is also provided at the position where the third rotating shaft 38 cooperates with the third hinge hole to reduce friction. Moreover, a sleeve is also provided on the third rotating shaft 38 to reduce the wear of the third hinge hole. A fourth end cover 53 is provided on the side of the connecting plate 37 away from the connecting seat 33 to connect with the third rotating shaft 38, thereby limiting the axial displacement of the third rotating shaft 38. An axial oil hole extending in the axial direction is provided on the third rotating shaft 38, and an end cover oil hole connected to the axial oil hole is provided on the fourth end cover 53.

[0066] In one embodiment of the present application, Figure 5 As shown, the connecting rod mechanism also includes a pair of ear plates 39 connected to the first end 311, the first end 311 is clamped between the pair of ear plates 39, the axle 12 is passed through the pair of ear plates 39 and is fixedly connected to the pair of ear plates 39, for example, the axle 12 and the ear plates 39 are connected by welding.

[0067] In one embodiment of the present application, Figure 2 and Figure 6 As shown, the connecting seat 33 is slidably sleeved on the guide column 212. The first connecting portion 331 of the connecting seat 33 is hinged to one section of the axle 12 through the second rotating shaft 32, the connecting sleeve 34 and the first end 311 of the connecting rod 31 in sequence, and the second connecting portion 332 of the connecting seat 33 is hinged to the other section of the axle 12 through the third rotating shaft 38 and the connecting plate 37 in sequence, so that both sides of the connecting seat 33 are hinged to the axle 12 respectively.

[0068] The lifting mechanism further includes a stopper 24 and a vibration-damping elastic member 25. The bottom end of the guide post 212 passes through the connection seat 33 and is exposed outside the connection seat 33. The stopper 24 is fixedly connected to the bottom end of the guide post 212. When the guide post 212 moves upward, the stopper 24 can abut against the bottom end surface of the connection seat 33 to prevent the guide post 212 from detaching from the connection seat 33 when it moves upward.

[0069] The top end of the guide post 212 extends radially outward to form a resisting portion 2121. The vibration damping elastic member 25 is sleeved on the guide post 212, and the two ends of the vibration damping elastic member 25 respectively abut against the resisting portion 2121 and the top surface of the connecting seat 33.

[0070] When the guide wheel 11 is in close fit with the steel rail 1, under the drive of the lifting drive member 20, the telescopic rod 211 drives the guide post 212 to extend downward, so as to compress the upper end of the vibration damping elastic member 25 through the resisting portion 2121. The lower end of the vibration damping elastic member 25 presses against the top surface of the connecting seat 33, and the connecting seat 33 presses against the axle 12 downward through the second rotating shaft 32 and the second rotating shaft 32, so that the guide wheel 11 can be in close contact with the steel rail 1. The pressure applied by the lifting drive member 20 to the guide wheel 11 is transmitted through the vibration damping elastic member 25. On the one hand, it can ensure that even if vibration occurs, the guide wheel 11 can always maintain close contact with the steel wheel, and it can prevent the guide wheel 11 from detaching from the steel rail 1 due to vibration. On the other hand, it can buffer the vibration at the guide wheel 11 and reduce the vibration transmitted from the guide wheel 11 to the vehicle frame 201.

[0071] As Figure 1 and Figure 6 shown, a debris remover 40 is further provided on the guide wheel 11. The debris remover 40 corresponds to the outer periphery of the guide wheel 11 and is used to remove slag, gravel, etc. on the guide wheel 11.

[0072] In order to make the two guide wheels 11 receive uniform force and be able to lift synchronously, in an embodiment of the present application, as Figure 2 shown, the guiding device 100 includes two sets of lifting mechanisms, two sets of link mechanisms and a cross beam. The two sets of lifting mechanisms are arranged at intervals along the width of the vehicle frame 201, the two sets of link mechanisms are arranged at intervals along the width of the vehicle frame 201, the lifting mechanisms and the link mechanisms are in one-to-one correspondence and cooperation, the two sets of lifting mechanisms are arranged between the two sets of link mechanisms, and the two ends of the cross beam are respectively connected to two links 31 in the two sets of link mechanisms, which is convenient to realize the synchronous movement of the two link mechanisms.

[0073] According to the second aspect of the embodiments of the present application, a vehicle body 200 is further provided. The vehicle body 200 is applied to a vehicle that can be used on both roads and railways. The vehicle body 200 includes a frame 201 and the guiding device 100 provided in any of the above embodiments. The guiding devices 100 are provided at both ends of the frame 201 along the length direction. The frame 201 can be a simple welded structure of profiled steel to serve as a load-bearing body. The frame 201 includes a chassis 202 and a connecting frame provided below the chassis 202. The connecting frame is connected to the chassis 202. The top end 22 of the cylinder barrel is hinged to the chassis 202 through a first movable hinge assembly 80, and the second end 312 of the connecting rod 31 is movably hinged to the connecting frame through a second movable hinge assembly 90. Since the vehicle body 200 can be guided on the rail 1 by using the above guiding device 100, the vehicle body 200 can be applied to a road vehicle and can also be applied to a vehicle that can be used on both roads and railways.

[0074] According to the second aspect of the embodiments of the present application, a vehicle is further provided. The vehicle includes a running system and the above vehicle body 200. The running system is provided below the chassis 202 and is used to drive the vehicle to run. Due to the above guiding device 100, the vehicle is convenient to walk and guide on the rail 1, and can also lift the guiding wheel 11 to walk on the road, which is applicable to any construction site and can meet the operation requirements of roads and railways.

[0075] Optionally, the vehicle further includes a guiding control system for controlling the lifting and lowering of the guiding wheel 11. In an embodiment of the present application, the guiding control system includes an electrical control system and a mechanical control device.

[0076] The electrical control system includes a control valve and a controller. The controller controls the oil inlet and oil return of the lifting drive 20 through the control valve, thereby controlling the lifting and lowering of the guiding wheel 11. Specifically, when the guiding control system determines that the preconditions for guiding the guiding wheel 11 are met, the guiding control system controls the oil circuit of the lifting drive 20, so that the rod chamber or the rodless chamber of the lifting drive 20 obtains oil pressure, and the movement of the telescopic rod 211 reaches the specified stroke, thereby driving the guiding wheel 11 to lift or lower to achieve the purpose of guiding the guiding wheel 11.

[0077] Furthermore, it can be extended that information is fed back to the steel wheel guiding control system before and after the execution of the steel wheel guiding to determine whether the steel wheel guiding operation has conditions or whether the steel wheel guiding operation has been completed.

[0078] The mechanical control device is used to manually control the lifting of the guide wheel 11, and the above-mentioned guiding control system does not participate in the control of the relevant lifting driving member 20 electrically. The mechanical control device includes a hand-operated pump, which is communicated with the oil inlet of the lifting driving member 20, so as to drive the hand-operated pump manually to realize the oil inlet and oil return of the oil circuit of the lifting driving member 20, and make the telescopic rod 211 of the lifting driving member 20 move to the specified stroke, thereby driving the guide wheel 11 to rise or fall, achieving the purpose of guiding the guide wheel 11. During operation, the telescopic rod 211 extends out, compresses the shock-absorbing elastic member 25, and the shock-absorbing elastic member 25 presses the guide wheel 11 tightly, which can prevent the shock-absorbing elastic member 25 from detaching from the rail 1 due to vibration.

[0079] The above control method for the guiding device 100 is simple and effective, easy to control, and has a low manufacturing cost, which is conducive to popularization and application.
