Bogie, adjusting method and transport vehicle

Abstract

The invention discloses a bogie, an adjusting method and a transport vehicle. The bogie comprises a framework; the wheel set assembly is mounted on the framework and used for being in rolling fit with the track; a spring; the bracket is connected with the framework through a spring; a first vertical interval is formed between the bracket and the framework; the positioning wheel assembly is mounted on the bracket and is in rolling fit with the track beam; the vertical limiting assembly is installed on the framework or the support and located in the first vertical interval. And a second vertical interval is formed between the vertical limiting assembly and the framework or the bracket. When side rolling of the vehicle body is larger than a design value, one side of the framework is lifted, after the framework is lifted, the second vertical interval is gradually reduced until the second vertical interval is reduced to 0, and when the second vertical interval is reduced to 0, the vertical limiting assembly abuts against the framework and the support, so that overturning of the vehicle body is prevented. When the wheels climb upwards along the rails, under the action of the vertical limiting assembly, the climbing height of the rims of the wheels climbing upwards along the rails is smaller than the minimum height of the rims of the wheels, and therefore the situation that the vehicle climbs the rails is avoided. In addition, if the vertical limiting assembly loses efficacy and the wheel rims transversely move along the rail and further increase, the transverse limiting assembly works, and therefore the vehicle is prevented from falling off the rail. Therefore, the derailment of the vehicle is avoided through the two measures.

[0002] Skyrail, also known as "suspended monorail", is a new type of medium and low-capacity rail transit system. The Skyrail train body is suspended under the track beam and "flies" in the air, and is called the "sky train".

[0026] In some embodiments, the second lateral spacing satisfies y1 < y < y2; where y is the second lateral spacing, y1 = y11 + y12, y11 is the maximum lateral displacement of the wheels of the wheel set relative to the track, and y12 is the maximum lateral displacement of the frame relative to the track; y2 = min(y21, y22), y21 is the minimum derailment distance of the wheels on the climbing rail side; y22 is the minimum derailment distance of the wheels on the non-climbing rail side.

[0042] In a third aspect, an embodiment of the present application provides a transport vehicle, comprising the bogie described in the first aspect.

[0043] The present invention has at least the following beneficial effects:

[0044] When the vehicle body roll is greater than the design value, the gravity moment of the vehicle body cannot balance the roll moment at the specified vehicle body roll angle, and the excess roll force on the vehicle body is transmitted to the frame, causing one side of the frame to lift. After the frame is lifted, the second vertical distance gradually decreases until it is reduced to 0. When it is reduced to 0, the vertical limit component abuts against the frame and the bracket, thereby preventing the frame from continuing to rise, thereby limiting the excessive roll of the vehicle body, thereby preventing the vehicle body from overturning and ensuring the safety of transportation.

[0045] And after the application is designed in this way, when the wheel traverses a large amount, the gap between the wheel and the track is reduced from a positive value to 0, and then the wheel rim climbs up along the track. When the wheel climbs up along the track, the frame on the same side thereof will be raised, and when the frame is raised to a maximum value (i.e., raised to the time when the vertical limit component is in contact with the frame and the support), the climbing height of the wheel rim along the track is less than the minimum height of the wheel rim, and then the track prevents the wheel from having a larger traverse amount, thereby avoiding the vehicle from climbing the track (climbing the track is a way of derailing), forming an anti-derailment measure, and preventing the vehicle from derailing.

[0046] In addition, if the vertical limit member fails and the wheel lateral displacement further increases, the wheel flange climbs to the top surface of the rail, and the second lateral interval gradually decreases until it is reduced to 0. When it is reduced to 0, the lateral limit member abuts against the track beam, thereby preventing the wheel from continuing to move laterally, thereby preventing the vehicle from derailing (derailing is another way of derailing), forming another anti-derailment measure.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0064] In the related art, there is a technical problem that the bogie is prone to overturning. The embodiment of the present application provides a bogie, an adjustment method and a transport vehicle, which can at least solve the technical problem that the bogie is prone to overturning to a certain extent.

[0065] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0066] like Figures 1 to 5 As shown, the bogie 100 includes a frame 110, a wheel set assembly 120, a spring assembly 130, a bracket 140, a positioning wheel assembly 150 and a vertical limit assembly 160. The wheel set assembly 120 is mounted on the frame 110 for rolling cooperation with the track 200; the bracket 140 is connected to the frame 110 through the spring assembly 130; the bracket 140 and the frame 110 have a first vertical interval; the positioning wheel assembly 150 is mounted on the bracket 140 for rolling cooperation with the track beam 300; the vertical limit assembly 160 is mounted on the frame 110 or the bracket 140 and is located in the first vertical interval; and the vertical limit assembly 160 and the frame 110 or the bracket 140 have a second vertical interval.

[0067] The wheel set assembly 120 is mounted on the frame 110, and the frame 110 is supported. The structure of the wheel set assembly 120 is diverse, and may include components such as axles, wheels 121, and load-bearing saddles. Specifically, the wheel set assembly 120 rolls with the track 200 through the wheels 121. The bracket 140 is used to support components such as the linear motor and the positioning wheel assembly 150. The positioning wheel assembly 150 may include components such as axles and positioning wheels. The circumferential surface of the positioning wheel of the positioning wheel assembly 150 rolls in contact with the track beam 300 located at the top of the bogie 100, so that there is a sufficient air gap between the linear motor and the track beam 300 to generate an electromagnetic driving force that meets the requirements.

[0068] The specific structures of the wheelset assembly 120, the positioning wheel assembly 150, the bracket 140 and the frame 110 are not limited in the present application, and those skilled in the art can make adaptive designs according to specific circumstances. The connection relationship between them is also known to those skilled in the art, and can be referred to the utility model patent with patent publication number CN218340601U and the invention patent with patent publication number CN116552590 A, which are not described in detail in the present application.

[0069] The frame 110 and the bracket 140 are connected by a spring assembly 130, which applies an upward force to the bracket 140. Under the action of the spring assembly 130, the positioning wheels of the positioning wheel assembly 150 are always in contact with the inner top wall of the track beam 300. Since the spring assembly 130 is elastic, it will be compressed and shortened when subjected to force. Therefore, in an environment with extremely strong crosswinds, one side of the frame 110 will be lifted toward the side close to the bracket 140, thereby overturning. In some embodiments, the frame 110 and the bracket 140 are also connected by a tie rod.

[0070] In the vertical direction, there is a first vertical interval between the bracket 140 and the frame 110. The vertical limit assembly 160 can be installed on the frame 110 or on the bracket 140. When the vertical limit assembly 160 is installed, the vertical limit assembly 160 is located in the first vertical interval. If the vertical limit assembly 160 is installed on the frame 110, there is a second vertical interval between the vertical limit assembly 160 and the bracket 140. If the vertical limit assembly 160 is installed on the bracket 140, there is a second vertical interval between the vertical limit assembly 160 and the frame 110.

[0071] After the present application is designed in this way, when the car body 400 installed on the frame 110 of the bogie 100 rolls under conditions such as extremely strong crosswinds, and the roll is less than the design value, the gravity moment of the car body 400 can balance the rolling moment at a limited roll angle of the car body 400. At this time, the vertical limit component 160 does not work. When the roll of the vehicle body 400 is greater than the design value, the gravity moment of the vehicle body 400 cannot balance the roll moment at the limited roll angle of the vehicle body 400, and the surplus roll force on the vehicle body 400 is transmitted to the frame 110, causing one side of the frame 110 to rise. After the frame 110 is lifted, the second vertical interval gradually decreases until it is reduced to 0. When it is reduced to 0, the vertical limit assembly 160 abuts against the frame 110 and the bracket 140, thereby preventing the frame 110 from continuing to rise, thereby limiting the excessive roll of the vehicle body 400, thereby preventing the vehicle body 400 from overturning and ensuring the safety of transportation.

[0072] After the present application is designed in this way, when the lateral displacement of the wheel 121 is small, both the running and parking of the vehicle are safe and derailment will not occur. When the lateral displacement of the wheel 121 is large, the gap between the wheel 121 and the track 200 decreases from a positive value to 0, and then the flange of the wheel 121 climbs upward along the track 200. When the wheel 121 climbs upward along the track 200, the same-side frame 110 will be lifted. When the frame 110 is lifted to the maximum value (that is, when the vertical limit assembly 160 abuts against both the frame 110 and the bracket 140), the climbing height of the flange of the wheel 121 along the track 200 is less than the minimum height h of the flange of the wheel 121, thereby preventing the track 200 from blocking a larger lateral displacement of the wheel 121, thus avoiding the vehicle from climbing the track (climbing the track is a form of derailment), forming a derailment prevention measure to prevent the vehicle from derailing.

[0073] The value of the second vertical interval can be adaptively set according to the first vertical interval, the dynamic deflection of the spring assembly 130, the dynamic deflection of the primary spring 165, etc., and is not limited in the present application. The second vertical interval should ensure that the spring assembly 130 has a certain deformation space and ensure that the vertical limit assembly 160 does not function during the normal running or parking of the vehicle. The second vertical interval should also ensure that before the flange of the wheel 121 reaches the top surface of the track 200, it abuts against the bracket 140 and the frame 110 to prevent the flange of the wheel 121 from climbing onto the top surface of the track 200, causing derailment of the climbing track type.

[0074] H is the second vertical interval. The magnitude of the lifting height z0 of the wheel 121 caused by the second vertical interval is related to the minimum height h of the flange of the wheel 121 and the dynamic deflection z1 of the primary spring 165 of the frame 110. The relationship can be summarized as: z1 < z0 < h. The magnitude relationship between H and z0 can be determined by methods such as the graphical method. The method of the graphical method is as follows: As Fig.11 shown, after determining the value of z0, according to the structural layout of the bogie 100 and the requirement that the vertical limit assembly 160 abuts against both the frame 110 and the bracket 140 during the maximum roll of the car body 400, by measuring Fig.10 the gap between the bracket 140 and the vertical limit assembly 160 on the drawing of the non-rolled car body 400, the magnitude of the second vertical interval H is determined.

[0075] In some embodiments, in order to ensure that both sides of the bogie 100 in the running direction can be evenly stressed and prevent the bogie 100 from being distorted, the bogie 100 includes a plurality of vertical limit assemblies 160, and the plurality of vertical limit assemblies 160 are respectively arranged on both sides of the frame 110 in the running direction and are located above the primary spring 165 of the bogie 100.

[0076] The structure and installation of the primary spring 165 are known to those skilled in the art. The primary spring 165 is disposed between the frame 110 and the wheelset assembly 120. Specifically, the primary spring 165 connects the frame 110 and the load-bearing saddle of the wheelset assembly 120, and can absorb shock and vibration.

[0077] In some embodiments, the bogie 100 has four primary springs 165 and four vertical limit assemblies 160 , two of which are arranged on each side of the traveling direction of the frame 110 , and each vertical limit assembly 160 is arranged directly above each primary spring 165 .

[0078] like Figure 5 As shown, in some embodiments, the vertical limit assembly 160 includes a vertical limit stopper 161 and a vertical adjustment member 162. A second vertical interval is provided between the vertical limit stopper 161 and the frame 110 or the bracket 140; the vertical adjustment member 162 is installed on the frame 110 or the bracket 140, and the output end of the vertical adjustment member 162 is connected to the vertical limit stopper 161; the vertical adjustment member 162 drives the vertical limit stopper 161 to move vertically to adjust the second vertical interval.

[0079] If the vertical adjustment member 162 is installed on the frame 110, there is a second vertical interval between the vertical limit stop 161 and the bracket 140, otherwise there is a second interval between the vertical limit stop 161 and the frame 110. The output end of the vertical adjustment member 162 is connected to the vertical limit stop 161, which can drive the vertical limit stop 161 to rise or fall vertically and stop at the position after the movement. After such a design, the vertical position of the vertical limit stop 161 can be adjusted by controlling the movement of the vertical adjustment member 162, thereby adjusting the value of the second vertical interval, so that the value of the second vertical interval can be adaptively adjusted according to different specific scenarios, which is convenient for the use of the bogie 100.

[0080] In some embodiments, the vertical stopper 161 includes a stopper support seat 1611 and a stopper body 1612. The stopper support seat 1611 has a mounting groove 1611a, and the stopper support seat 1611 is mounted on the output end of the vertical adjustment member 162; the stopper body 1612 is elastic, and the stopper body 1612 is mounted in the mounting groove 1611a and at least partially extends out of the mounting groove 1611a.

[0081] After such design, since the stopper body 1612 is elastic, the stopper body 1612 can absorb part of the impact energy when the stopper body 1612 contacts the bracket 140 or the frame 110, which helps to reduce the direct impact of the stopper body 1612 on the bracket 140 or the frame 110, reduce the vibration and noise generated thereby, and help to make the bogie 100 run more smoothly and safely. It should be noted that when the stopper body 1612 can be compressed to the condition that it does not extend out of the installation groove 1611a, the second vertical interval refers to the vertical interval between the stopper support seat 1611 and the bracket 140 or the frame 110. When the stopper body 1612 is compressed to the limit, if the stopper body 1612 still extends out of the installation groove 1611a, the second vertical interval refers to the vertical interval between the stopper body 1612 and the bracket 140 or the frame 110 when the stopper body 1612 is compressed to the limit.

[0082] like Figure 5 As shown, in some embodiments, the vertical adjustment member 162 is installed on the frame 110, and the limit stop body 1612 can be compressed to be completely located in the installation groove 1611a. In these embodiments, the second vertical interval refers to the limit stop support seat 1611 and the bracket 140, that is, Figure 5 H in.

[0083] In some embodiments, the vertical limit assembly 160 further includes a vertical spacing detector 170 and a controller. The vertical spacing detector 170 is installed at the output end of the vertical adjustment member 162 or the vertical limit stopper 161, and the vertical spacing detector 170 is used to detect the detection value of the second vertical spacing; the controller is electrically connected to the vertical spacing detector 170 and the vertical adjustment member 162; the controller controls the vertical adjustment member 162 to operate based on the detection value of the second vertical spacing fed back by the vertical spacing detector 170, so that the detection value of the second vertical spacing reaches the set value of the second vertical spacing.

[0084] Before the transport vehicle is in operation, the vertical spacing detector 170 detects the detection value of the second vertical spacing and sends the detection value of the second vertical spacing to the controller. The controller compares the detection value of the second vertical spacing with the set value of the second vertical spacing. When the two are not equal, a control signal is sent to the vertical adjustment member 162 according to the size of the deviation, so that the vertical adjustment member 162 drives the vertical limit stop 161 to move, thereby adjusting the second vertical spacing so that the detection value of the second vertical spacing is equal to the set value of the second vertical spacing. With this design, before the transport vehicle is in operation, the second vertical spacing can be automatically detected and adjusted, reducing the need for manual intervention, thereby reducing downtime and maintenance time, and reducing maintenance costs. And with this design, during the transportation of the transport vehicle, the detection value of the second vertical spacing can be sent to the controller in real time, realizing real-time online detection of the detection value of the second vertical spacing, which helps to improve the safety of the transport vehicle.

[0085] In some embodiments, the vertical adjustment member 162 is installed on the frame 110, and the vertical limit assembly 160 also includes a vertical adjustment pad 175, which is arranged between the vertical adjustment member 162 and the frame 110, and / or, between the vertical adjustment member 162 and the vertical limit stop 161.

[0086] The vertical adjustment pad 175 can be arranged between the vertical adjustment member 162 and the frame 110, or between the vertical adjustment member 162 and the vertical limit stop 161. It should be noted that there are multiple vertical adjustment members 162, and the vertical limit stop 161 can be brought close to the bracket 140 by increasing the number of vertical adjustment pads 175, thereby reducing the second vertical interval. It is also possible to increase the second vertical interval by reducing the number of vertical adjustment pads 175 so that the vertical limit stop 161 is away from the bracket 140. After such a design, the second vertical interval can be adjusted by the operator manually increasing or decreasing the number of adjustment pads, so that when the vertical spacing detector 170, the controller, the vertical adjustment member 162 and other components fail or are damaged, the second vertical interval can still be effectively adjusted to ensure the stable operation and safety of the bogie 100 and prevent the bogie 100 from overturning.

[0087] In some embodiments, the vertical adjustment member 162 and the frame 110 are connected by bolts and nuts, and a plurality of vertical adjustment pads 175 are provided. The plurality of vertical adjustment members 162 are stacked vertically and placed between the vertical adjustment member 162 and the frame 110. Under the action of the bolts and nuts, the vertical adjustment member 162 and the frame 110 clamp the plurality of vertical adjustment pads 175 therebetween. When the number of vertical adjustment pads 175 needs to be increased or decreased, the bolts and nuts are removed to perform the operation.

[0088] When the vertical limit component 160 fails, after the wheel 121 edge climbs to the top surface of the track 200, the wheel 121 still has the risk of falling off the track. In some embodiments, such as Figure 3 and Figure 5 As shown, there is a first lateral interval between the frame 110 and the track beam 300; the bogie 100 also includes a lateral limit assembly 180 installed on the frame 110, and the lateral limit assembly 180 is located in the first lateral interval; there is a second lateral interval between the lateral limit assembly 180 and the track beam 300.

[0089] In the transverse direction, there is a first transverse interval between the frame 110 and the track beam 300, and the transverse limit assembly 180 is installed on the frame 110 and is located in the first transverse interval. In the transverse direction, there is a second transverse interval between the transverse limit assembly 180 and the track beam 300. With this design, when the wheel 121 has a small transverse displacement, the vehicle is safe to run and park, and derailment will not occur. When the wheel 121 has a large transverse displacement, the gap between the wheel 121 and the track 200 decreases from a positive value to 0, and then the wheel rim of the wheel 121 climbs up along the track 200. When wheel 121 climbs up along track 200, the framework 110 on the same side can be raised, and when framework 110 is raised to maximum value H, the upper end surface of limit stop support seat 1611 abuts against the lower end surface of support 140, and the climbing amount of its wheel 121 wheel rim climbing along track 200 is less than the minimum height h of wheel 121 wheel rim, and then track 200 is prevented from the larger lateral displacement of wheel 121, thereby avoiding the vehicle from climbing track (climbing track is a kind of mode of derailment), forming the first anti-derailment measure. If vertical limit composition 160 fails, after wheel 121 wheel rim climbs to track 200 top surface, the second lateral interval between lateral limit composition 180 and track beam 300 inner side surface is reduced, until it is reduced to 0. At this moment, track beam 300 inner side prevents excessive lateral displacement of framework 110, and then prevents excessive lateral displacement of wheel 121 by framework 110, thereby preventing wheel 121 from derailing (derailing is another mode of derailment), thereby forming the second anti-derailment measure. The present application forms two anti-derailment measures under the joint action of vertical limit composition 160 and lateral limit composition 180, can effectively avoid wheel 121 derailment, ensure the safety of transportation.

[0090] The specific setting value of the second lateral interval is related to the minimum derailment distance of the wheel 121 on the climbing side and the minimum derailment distance on the non-climbing side, etc. The user can make an adaptive design according to the specific situation, and it is not limited in this application.

[0091] In some embodiments, the second lateral interval satisfies y1 < y < y2; where y is the second lateral interval, y1 = y11 + y12, y11 is the maximum lateral displacement of the wheel 121 of the wheel set assembly 120 relative to the track 200, and y12 is the maximum lateral displacement of the frame 110 relative to the track 200, as Fig. 9 shown; y2 = min(y21, y22), y21 is the minimum derailment distance of the wheel 121 on the climbing rail side; y22 is the minimum derailment distance of the wheel 121 on the non-climbing rail side, as Figure 8 shown. When actually determining y, manufacturing, installation and other errors usually need to be considered, and an appropriate safety margin should be left. In some embodiments, a safety margin of 3 mm to 5 mm is left.

[0092] In some embodiments, the lateral limit assembly 180 includes a lateral limit assembly 180 and a lateral adjuster 182. There is a second lateral interval between the lateral limit assembly 180 and the track beam 300; the lateral adjuster 182 is installed on the frame 110, the output end of the lateral adjuster 182 is connected to the lateral limit assembly 180, and the lateral adjuster 182 drives the lateral limit block 181 to move laterally to adjust the second lateral interval.

[0093] The lateral adjuster 182 drives the lateral limit block 181 to move laterally and stops at the position after movement. After such a design, the position of the lateral limit block 181 can be adjusted by controlling the movement of the lateral adjuster 182, thereby adjusting the value of the second lateral interval, so that the value of the second lateral interval can be adaptively adjusted according to different specific scenarios, facilitating the use of the bogie 100.

[0094] In some embodiments, the lateral limit assembly 180 further includes a lateral spacing detector 185 and a controller. The lateral spacing detector 185 is disposed on the lateral limit assembly 180 or the output end of the lateral adjuster 182, and the lateral spacing detector 185 is used to detect the detected value of the second lateral interval; the controller is electrically connected to both the lateral spacing detector 185 and the lateral adjuster 182; the controller controls the action of the lateral adjuster 182 based on the detected value of the second lateral interval fed back by the lateral spacing detector 185, so that the detected value of the second lateral interval reaches the set value of the second lateral interval.

[0095] The lateral spacing detector 185 detects the detection value of the second lateral spacing and sends the detection value of the second lateral spacing to the controller. The controller compares the detection value of the second lateral spacing with the set value of the second lateral spacing. When the two are not equal, a control signal is sent to the lateral adjustment member 182 according to the size of the deviation, so that the lateral adjustment member 182 drives the lateral limit stop 181 to move, thereby adjusting the detection value of the second lateral spacing, so that the detection value of the second lateral spacing is equal to the set value of the second lateral spacing. With this design, the second lateral spacing can be automatically detected and adjusted, reducing the need for manual intervention, thereby reducing downtime and maintenance time, and reducing maintenance costs. And with this design, during the transportation of the transport vehicle, the detection value of the second lateral spacing can be sent to the controller in real time, realizing real-time online detection of the detection value of the second lateral spacing, which helps to improve the safety of the transport vehicle.

[0096] In some embodiments, the transverse limiting assembly 180 includes a mounting seat 1811 and a limiting wheel 1812. The mounting seat 1811 is mounted on the output end of the transverse adjusting member 182; the limiting wheel 1812 is rotatably connected to the mounting seat 1811, and a second transverse interval is formed between the limiting wheel 1812 and the track beam 300.

[0097] The lateral adjustment member 182 drives the mounting seat 1811 to move laterally, thereby driving the limiting wheel 1812 on the mounting seat 1811 to move laterally. When the limiting wheel 1812 moves to contact the track beam 300, it prevents the wheel 121 from continuing to move laterally, thereby preventing the wheel 121 from falling off the track. It should be noted that the axis of the limiting wheel 1812 is arranged in the vertical direction. After such a design, when the limiting wheel 1812 moves to contact the track beam 300, the circumferential surface of the limiting wheel 1812 contacts the track beam 300, and the rolling contact between the limiting wheel 1812 and the track beam 300 helps to reduce the friction between the limiting wheel 1812 and the track beam 300, and improves the stability of the movement of the transport vehicle.

[0098] In some embodiments, the lateral limiting assembly 180 further includes a lateral adjustment pad 190 ; the lateral adjustment pad 190 is disposed between the lateral adjusting member 182 and the frame 110 , and / or, between the lateral adjusting member 182 and the lateral limiting stop 181 .

[0099] The lateral adjustment pad 190 can be arranged between the lateral adjustment member 182 and the frame 110, or between the lateral adjustment member 182 and the mounting seat 1811. It should be noted that there are multiple lateral adjustment members 182, and the lateral limit stop 181 can be made close to the track beam 300 by increasing the number of lateral adjustment pads 190, thereby reducing the second lateral interval. It is also possible to increase the second lateral interval by reducing the number of lateral adjustment pads 190 so that the lateral limit stop 181 is away from the track beam 300. After such a design, the second lateral interval can be adjusted by the operator manually increasing or decreasing the number of adjustment pads, which is convenient for effectively adjusting the second lateral interval in the event of failure or damage of components such as the lateral spacing detector 185, the controller, and the lateral adjustment member 182, thereby ensuring the stable operation and safety of the bogie 100 and preventing the bogie 100 from derailing.

[0100] When the bogie 100 is assembled, the second vertical interval can be adjusted to a set value by adding or subtracting the vertical adjustment pad 175 , and the second lateral interval can be adjusted to a set value by adding or subtracting the lateral adjustment pad 190 .

[0101] In some embodiments, the lateral adjustment member 182 and the mounting seat 1811 are connected by bolts and nuts, and a plurality of lateral adjustment pads 190 are provided. The plurality of lateral adjustment members 182 are stacked in the lateral direction and placed between the lateral adjustment member 182 and the mounting seat 1811. Under the action of the bolts and nuts, the lateral adjustment member 182 and the mounting seat 1811 clamp the plurality of lateral adjustment pads 190 therebetween. When the number of lateral adjustment pads 190 needs to be increased or decreased, the bolts and nuts can be removed to perform the operation.

[0103] In some embodiments, four lateral limiting assemblies 180 are provided, with two lateral limiting assemblies 180 provided on each side of the traveling direction of the frame 110 .

[0107] S300, an adjustment step, controlling the vertical limit component 160 and / or the lateral limit component 180 to move according to the judgment result of the judgment step, and executing the detection step again.

When it is detected that the detection value of the second vertical spacing is not equal to the set value of the second vertical spacing, the controller sends a control signal to the vertical adjustment member 162 according to the deviation, so that the vertical adjustment member 162 drives the vertical limit stop 161 to move, thereby adjusting the second vertical spacing, so that the detection value of the second vertical spacing is equal to the set value of the second vertical spacing. When it is detected that the detection value of the second lateral interval is not equal to the set value of the second lateral interval, the controller sends a control signal to the lateral adjustment member 182 according to the deviation size, so that the lateral adjustment member 182 drives the lateral limit stop 181 to move, thereby adjusting the detection value of the second lateral interval so that the detection value of the second lateral interval is equal to the set value of the second lateral interval.
