Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, and more specifically, to a car body support device and a straddle-type monorail vehicle production line. Background Technology

[0002] In transportation systems such as straddle-type monorail transit, during the vehicle assembly process, it is necessary to install components such as interior trim inside the vehicle body, as well as components such as bogies under the vehicle body. Since the bottom of the vehicle body is usually uneven, during the vehicle assembly process, it is usually necessary to lift the vehicle body onto a support device, which then supports the vehicle body.

[0003] Currently, in the case of installing components inside the vehicle body and in the case of installing components under the vehicle body, support devices of different height specifications are often used to support the vehicle body. The support devices have low versatility in different working conditions, and in the case of working conditions requiring higher support height, the support devices often occupy a large space, which is not conducive to the lightweight design of the support devices. Utility Model Content

[0009] Optionally, a second connecting hole is provided on the stop plate opposite to the first connecting hole of the columnar structure, and the limiting connector passes through the first connecting hole and the second connecting hole; And / or, the columnar structure is a vehicle anti-nodding torsion seat; When the columnar structure is provided with the first connecting hole, the stop plate is provided with the second connecting hole, and the columnar structure is the anti-nodding torsion seat, the first connecting hole is also used to install the anti-nodding torsion bar mechanism.

[0010] Optionally, the support frame further includes a fastening structure. The fixed frame has a guide hole with an open top. The lifting frame is movably inserted into the guide hole in the vertical direction. The fixed frame has a third connecting hole. The lifting frame has a fourth connecting hole. The fastening structure passes through the third connecting hole and the fourth connecting hole. At least one of the third connecting hole and the fourth connecting hole has multiple holes spaced apart in the vertical direction.

[0011] Optionally, the lifting frame includes a guide column located below the support platform, the top end of the guide column being connected to the bottom end of the support platform, the projection of the support platform in the horizontal plane in the vertical direction covering the projection of the guide column in the horizontal plane in the vertical direction, the guide column being inserted into the guide hole and slidably connected to the guide hole, the length of the guide column being less than or equal to the depth of the guide hole, the guide column being provided with a plurality of the fourth connecting holes, and the fixing frame being provided with a plurality of the third connecting holes.

[0012] Optionally, the two fixing brackets are spaced apart in the left and right directions of the vehicle body, and the fixing brackets are adjustablely connected to the support frame in the left and right directions.

[0013] Optionally, the support frame is provided with a guide rail extending in the left-right direction, and the fixing frame is slidably connected to the guide rail; And / or, the fixing frame includes a column and a base plate connected to the bottom end of the column, the lifting frame is connected to the column, the base plate is provided with a fifth connecting hole, the bearing frame is provided with a sixth connecting hole, the fifth connecting hole and the sixth connecting hole are connected, and the distance from the inner edge of the base plate in the left-right direction to the column is greater than the distance from the inner edge of the base plate in the left-right direction to the column. And / or, the support frame includes a horizontal frame and a vertical frame, with two vertical frames spaced apart in the left-right direction and respectively connected to both ends of the support frame, and a designated space formed between the two vertical frames below the horizontal frame is used to accommodate the transport trolley.

[0014] Secondly, this utility model provides a straddle-type monorail vehicle production line, which includes at least one support station that requires support for the vehicle body, and at least one support station is provided with a vehicle body support device as described in any of the first aspects above; when at least two support stations are respectively provided with the vehicle body support device, the bearing frame of the vehicle body support device at at least two support stations is in a different position in the vertical direction.

[0015] In the vehicle body support device and straddle-type monorail vehicle production line of this utility model, the vehicle body support device can be arranged at the bottom of the vehicle body. For example, two vehicle body support devices are distributed at intervals in the front-rear direction of the vehicle body. In each vehicle body support device, a load-bearing frame supports, for example, two left and right support frames. Each support frame is used to connect to the columnar structure at the bottom of the vehicle body through its liftable lifting frame. In scenarios where work needs to be carried out under the vehicle body, such as when installing components on the vehicle body floor, the lifting frame can be raised to a vertical position, and the columnar structure can be used to provide some operating space under the vehicle body, avoiding direct connection between the lifting frame and the vehicle body floor. By avoiding relying entirely on the vertical dimensions of the vehicle body support device to provide operating space under the vehicle body, the height requirement at the upper limit of the lifting frame can be reduced, thus reducing the volume of the vehicle body support device. In scenarios where work needs to be carried out inside the vehicle body, such as when installing components inside the vehicle body, the vertical position of the lifting frame can be lowered, reducing the difficulty for operators to climb into the vehicle body. At the same time, the lifting frame supports the bottom of the columnar structure through its top support platform, and the stop plates are arranged on the sides of the columnar structure. The stop plates can form a stop on the columnar structure to prevent the supported vehicle body from slipping, thus ensuring the reliability of the support for the vehicle body. Overall, the vehicle body support device of this utility model can adjust the support height of the vehicle body as needed, and can be used for multiple support positions of the vehicle body to meet the support height requirements of multiple support positions. In addition, it can provide a part of the operating space under the vehicle body by using the column structure, which can reduce the upper limit position of the lifting frame and the lifting stroke requirements, which is conducive to the miniaturization and weight reduction of the vehicle body support device. The design of the support platform and the stop plate can prevent the supported vehicle body from slipping and ensure the reliability of the support for the vehicle body. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0023] like Figure 1 and Figure 2 As shown, an embodiment of this utility model provides a vehicle body support device. The vehicle body support device A includes a carrier frame 1 and a support frame 2, with multiple support frames 2 spaced apart on the carrier frame 1. The support frame 2 includes a fixed frame 21 and a lifting frame 22. The fixed frame 21 is connected to the carrier frame 1, and the lifting frame 22 is adjustablely connected to the fixed frame 21 in the vertical direction. The top of the lifting frame 22 is provided with a support platform 221 and a stop plate 222. The support platform 221 is connected to one or more sides of the circumferential direction with stop plates 222. The support platform 221 is used to support the bottom end of the columnar structure 31 at the bottom of the vehicle body 3, and the stop plate 222 is used to be arranged on the side of the columnar structure 31 to limit the side of the columnar structure 31.

[0024] like Figure 1 As shown, two vehicle body support devices are distributed at intervals in the front-rear direction of the vehicle body 3. In each vehicle body support device, the load-bearing frame 1 serves as the basic frame, and two support frames 2 are installed at intervals along the left-right direction of the vehicle body 3 on the load-bearing frame 1. For example, four support frames 2 together support the vehicle body 3. The structure of the load-bearing frame 1 is not limited, as long as it can distribute the supporting force transmitted by the two support frames 2. It is usually composed of multiple structural components connected by means such as welding.

[0025] The specific cross-sectional shape of the columnar structure 31 of the base plate 212 of the car body 3 is not limited. It is usually used as the mounting base for the components under the car body 3. In this specification, taking the car body 3 as the car body 3 of a straddle-type monorail vehicle as an example, the columnar structure 31 can be used as an anti-head-sway torsion bar seat. The columnar structure 31 can be provided with a first connecting hole 311. The first connecting hole 311 is used for subsequent connection with the anti-head-sway torsion bar mechanism. It is not limited to this, and will not be described in detail here.

[0026] The lifting mechanism of the lifting frame 22 relative to the fixed frame 21 in the support frame 2 is not limited. It can be adjusted manually, electrically or pneumatically, or semi-manually. The relevant technologies can be used, but will not be described in detail here.

[0027] The stop plate 222 can be configured as needed. In some scenarios, in the left-right direction, the stop plate 222 is provided on the inner side (the side closer to the center of the vehicle body 3 in the width direction) and / or the outer side of the support platform 221, so that the stop plate 222 can realize the position positioning of the vehicle body 3 and the vehicle body support device in the left-right direction. In some scenarios, in the front-back direction, the stop plate 222 is provided on the inner side (the side closer to the center of the vehicle body 3 in the front-back direction) and / or the outer side of the support platform 221, so that the stop plate 222 can realize the position positioning of the vehicle body 3 and the vehicle body support device in the front-back direction.

[0028] The vehicle body support device of this utility model embodiment can be arranged at the bottom of the vehicle body 3. For example, two vehicle body support devices are distributed at intervals in the front-rear direction of the vehicle body 3. In each vehicle body support device, a bearing frame 1 supports, for example, two left and right support frames 2. Each support frame 2 is used to connect to the columnar structure 31 at the bottom of the vehicle body 3 through its liftable lifting frame 22. In scenarios where work needs to be carried out under the vehicle body 3, such as when components need to be installed on the bottom plate 212 of the vehicle body 3, the lifting frame 22 can be raised to a vertical position, and the columnar structure 31 can be used to provide some operating space under the vehicle body 3, avoiding direct connection of the lifting frame 22 to the bottom plate 212 of the vehicle body 3, thereby avoiding complete reliance on the vehicle body support. The vertical dimensions of the support device provide operating space below the vehicle body 3, reducing the height requirement at the upper limit position of the lifting frame 22 and reducing the volume of the vehicle body support device. In scenarios where operations need to be carried out inside the vehicle body 3, such as when installing components inside the vehicle body 3, the vertical position of the lifting frame 22 can be lowered, reducing the difficulty for operators to climb into the vehicle body 3. At the same time, the lifting frame 22 supports the bottom end of the columnar structure 31 through the support platform 221 at its top. The stop plate 222 is arranged on the side of the columnar structure 31, which can stop the columnar structure 31 and prevent the supported vehicle body 3 from slipping, thus ensuring the reliability of the support for the vehicle body 3. In general, the vehicle body support device of this utility model can adjust the support height of the vehicle body 3 as needed, and can be used for multiple support positions of the vehicle body 3 to meet the support height requirements of the vehicle body 3 at multiple support positions. In addition, it can use the column structure 31 to provide a part of the operating space under the vehicle body 3, which can reduce the upper limit position and lifting stroke requirements of the lifting frame 22, which is conducive to the miniaturization and weight reduction of the vehicle body support device. The design of the support platform 221 and the stop plate 222 can position the column structure 31 to prevent the supported vehicle body 3 from slipping, and can ensure the reliability of the support for the vehicle body 3.

[0029] like Figure 2 As shown, optionally, the stop plate 222 extends circumferentially along the support platform 221 and is connected end to end. The support platform 221 and the end-to-end connected stop plate 222 are connected to form a groove structure.

[0030] When arranging the vehicle body support device, the vehicle body 3 is lifted using, for example, hoisting equipment. The vehicle body support device is placed below the vehicle body 3, aligning the slots of each grooved structure with the lower ends of each columnar structure 31. The position of the lifting frame 22 in the vertical direction is adjusted, and then the position of the vehicle body 3 is gradually lowered to achieve support for the vehicle body 3 by the vehicle body support device. During this process, the grooved structure can guide the lower ends of the columnar structures 31 to a certain extent, ensuring the stability of the relative position of the grooved structure and the columnar structure 31 during the descent of the vehicle body 3.

[0031] The trough-shaped structure completely surrounds the columnar structure 31. When the vehicle body 3 is subjected to forces in the front-rear or left-right directions, the continuous sidewalls of the stop plate 222 can provide restraint, forming a stop on the columnar structure 31 and reducing the risk of slippage of the vehicle body 3 in the front-rear or left-right directions. The stop plate 222 and the support platform 221 are usually integrally connected to reduce local stress concentration.

[0032] like Figure 4 and Figure 5 Main reference Figure 5 As shown, optionally, the top of the support platform 221 is provided with an anti-slip pad 224.

[0033] Specifically, the anti-slip mat 224 contacts the bottom end of the columnar structure 31, and the projection of the protective mat in the horizontal plane in the vertical direction covers the projection of the bottom surface of the columnar structure 31 in the horizontal plane in the vertical direction.

[0034] The anti-slip mat 224 can be made of wear-resistant rubber. The elasticity of the wear-resistant rubber can adapt to the irregular shape (such as rust or unevenness) of the columnar structure 31 to a certain extent.

[0035] The anti-slip pad 224 helps to eliminate the adverse effects that may be caused by the positional accuracy error of the bottom surface of the columnar structure 31 and the upper surface of the support platform 221. It can ensure the integrity of the contact between the vehicle body support device and the bottom surface of the columnar structure 31, ensure the reliability of the vehicle body support device in supporting the vehicle body 3, and reduce the possibility of the vehicle body 3 slipping. It has a simple structure and strong practicality.

[0036] like Figure 4 and Figure 5 Main reference Figure 5 As shown, optionally, the support platform 221 is provided with a receiving groove 2211, and the anti-slip pad 224 is at least partially received in the receiving groove 2211.

[0037] The anti-slip mat 224 can be arranged in the receiving groove 2211 by means of bonding, fastener connection or other methods. The receiving groove 2211 can provide an installation reference for the anti-slip mat 224, and the groove wall of the receiving groove 2211 can also abut against the anti-slip mat 224 to ensure the positional reliability of the anti-slip mat 224, thereby ensuring the reliability of the vehicle body support device in supporting the vehicle body 3.

[0038] In the above embodiments, optionally, the anti-slip pad 224 is provided with a through hole, and the support platform 221 is provided with a communication structure communicating with the through hole (not shown in the figure of this scheme).

[0039] Specifically, the via extends in the vertical direction, and the connecting structure extends in the vertical or horizontal direction. During the contact between the column 211 structure and the anti-slip pad 224, the gas or liquid in the contact gap can be discharged through the via and the connecting structure to avoid liquid accumulation corrosion and extend the life of the anti-slip pad 224.

[0040] In the above embodiments, optionally, the columnar structure 31 is a vehicle anti-nodding torsion seat.

[0041] Specifically, in a straddle-type monorail transit system, the column structure 31 serves as an anti-torsional support for the vehicle, used to mount an anti-torsional bar mechanism. In this case, the column structure 31 can be equipped with a mechanism for mounting the anti-torsional bar mechanism, for example, by setting... Figure 5 The first connecting hole 311 is shown. The columnar structure 31 can also be a structure arranged on the vehicle body 3 for other needs, which will not be described in detail here.

[0042] Optionally, in the above embodiments, reference is made to... Figure 5 As shown, a second connecting hole (not shown in the figure) is provided on the stop plate 222 opposite to the first connecting hole 311 of the columnar structure 31, and the limiting connector (not shown in the figure) passes through the first connecting hole 311 and the second connecting hole.

[0043] Thus, when the first connecting hole 311 and the second connecting hole are aligned, the limiting connector can be inserted through the first connecting hole 311 and the second connecting hole, so that the columnar structure 31 and the lifting frame 22 are connected by the limiting connector, thereby limiting their relative displacement in the vertical direction.

[0044] In some scenarios, the positions of the first connecting hole 311 and the second connecting hole correspond, and the first connecting hole 311 is also used to install the anti-nodding torsion bar mechanism.

[0045] In another embodiment, the stop plate 222 of the vehicle body support device may not have a second connecting hole, and the column structure 31 may be supported only by the support platform 221 and the column structure 31 may be limited by the stop plate 222.

[0046] like Figure 5As shown, optionally, the support frame 2 also includes a fastening structure 23. The fixed frame 21 is provided with a guide hole 2111 with an open top. The lifting frame 22 is movably inserted into the guide hole 2111 in the vertical direction. The fixed frame 21 is provided with a third connecting hole 2112. The lifting frame 22 is provided with a fourth connecting hole 2231. The fastening structure 23 passes through the third connecting hole 2112 and the fourth connecting hole 2231. At least one of the third connecting holes 2112 and the fourth connecting hole 2231 is distributed in multiples at intervals in the vertical direction.

[0047] Specifically, the third connecting hole 2112 and the fourth connecting hole 2231 are aligned axially. Figure 5 In the design, the third connecting hole 2112 penetrates the column 211 of the fixed frame 21 along the Y-axis, and the fourth connecting hole 2231 penetrates the lifting frame 22 along the X-axis. The fastening structure 23 includes a bolt and a nut. The bolt passes through the third connecting hole 2112 and the fourth connecting hole 2231, and the threaded end of the bolt is connected to the nut. By switching the pairing combination of the third connecting hole 2112 and the fourth connecting hole 2231, the position of the lifting frame 22 in the vertical direction relative to the fixed frame 21 can be adjusted.

[0048] like Figure 5 As shown, the lifting frame 22 further includes a guide column 223 located below the support platform 221. The top end of the guide column 223 is connected to the bottom end of the support platform 221. The projection of the support platform 221 in the horizontal plane in the vertical direction covers the projection of the guide column 223 in the horizontal plane in the vertical direction. The guide column 223 is inserted into the guide hole 2111 and is slidably connected to the guide hole 2111. The length of the guide column 223 is less than or equal to the depth of the guide hole 2111. The guide column 223 is provided with a plurality of fourth connecting holes 2231, and the fixing frame 21 is provided with a plurality of third connecting holes 2112.

[0049] The projection of the support platform 221 on the horizontal plane completely covers the projection of the guide column 223. The support platform 221 can achieve a large horizontal dimension, thereby ensuring that its size can meet the requirements for connection with the column structure 31. When the guide column 223 is completely contained in the guide hole 2111, the vertical load borne by the support platform 221 can be directly transferred to the fixed frame 21. In this case, the exposure of the lifting guide column 223 can be avoided, and there is no need to connect the fastening structure 23.

[0050] like Figure 2 As shown, optionally, in the above embodiment, two fixing frames 21 are spaced apart in the left and right directions of the vehicle body 3, and the fixing frames 21 are tunably connected to the support frame 1 in the left and right directions.

[0051] In this way, by adjusting the position of the fixing bracket 21 in the left and right directions, it can be adapted to different sizes of vehicle bodies 3. Specifically, it can be adapted to vehicle bodies 3 with different distances between the two left and right columnar structures 31, thereby improving the applicability of the vehicle body support device.

[0052] like Figure 2 As shown, optionally, the support frame 1 is provided with a guide rail 13 extending in the left and right direction, and the fixing frame 21 is slidably connected to the guide rail 13.

[0053] like Figure 2 As shown, the support frame 1 may include a frame body 11 and a support plate 12 disposed above the frame body 11. The frame body 11 may be connected by multiple structural components, such as by welding. The support plate 12 may be integrally connected to the frame body 11 or detachably connected. The guide rail 13 is disposed on the support plate 12. The fixed frame 21 is slidably connected to the guide rail 13 in the left and right directions. The fixed frame 21 may be provided with a guide groove that matches the guide rail 13, such as a dovetail groove.

[0054] In this way, the movement of the fixed frame 21 in the left and right directions can be guided by the guide rail 13, reducing the difficulty of adjusting the position of the fixed frame 21 in the left and right directions.

[0055] like Figure 2 As shown, the support frame 1 includes a horizontal frame 111 and a vertical frame 112. The two vertical frames 112 are spaced apart in the left and right directions and are respectively connected to the two ends of the support frame 1. The space enclosed between the two vertical frames 112 below the horizontal frame 111 is used to accommodate the transport trolley.

[0056] Specifically, the frame body 11 includes a horizontal frame 111 and a vertical frame 112 welded together. The structural design of the frame body 11 allows the AGV transport trolley to move in the front-back direction to the bottom of the horizontal frame 111, and to transport and transfer the vehicle body transport device through the AGV transport trolley.

[0057] like Figure 2 As shown, optionally, the fixed frame 21 includes a column 211 and a base plate 212 connected to the bottom end of the column 211. The lifting frame 22 is connected to the column 211. The base plate 212 is provided with a fifth connecting hole 2121. The support frame 1 is provided with a sixth connecting hole 121. The fifth connecting hole 2121 and the sixth connecting hole 121 are connected.

[0058] Specifically, the fifth connecting hole 2121 is an elongated hole of color along the left and right direction, which is provided on the base plate 212. Multiple holes can be provided. The sixth connecting hole 121 is a round hole. The sixth connecting hole 121 is arranged on the support plate 12 and is provided at intervals in the left and right direction. Fasteners pass through the fifth connecting hole 2121 and are threadedly connected to the sixth connecting hole 121.

[0059] Furthermore, the distance from the inner edge of the base plate 212 in the left-right direction to the column 211 is greater than the distance from the outer edge of the base plate 212 in the left-right direction to the column 211. The inner edge is the edge of the base plate 212 in the left-right direction near the center of the vehicle body 3, and the outer edge is the edge of the base plate 212 in the left-right direction near the outside of the vehicle body 3.

[0060] In this way, the contact surface between the base plate 212 and the support plate 12 of the support frame 1 can be ensured. For example, more fasteners can be arranged on this contact surface to ensure the reliability of the connection between the fixing frame 21 and the support frame 1. At the same time, the size of the support frame 1 in the left and right directions will not be too large due to ensuring the contact area with the base plate 212. This is conducive to the miniaturization and lightweight design of the vehicle body support device, with a simple structure and strong practicality.

[0061] Another embodiment of this utility model provides a straddle-type monorail vehicle production line, which includes at least one support station that requires support for the vehicle body 3, and the vehicle body support device of the above embodiment is arranged at at least one support station.

[0062] Specifically, the two vehicle body support devices are distributed at intervals in the front-rear direction of the vehicle, and the support frames 2 of the two vehicle body support devices together support the vehicle body 3.

[0063] Furthermore, when a vehicle body support device is arranged at at least two support stations, the load-bearing frame 1 of the vehicle body support device at at least two support stations is in a different position in the vertical direction.

[0064] For example, in two support stations, the support frame 1 of the vehicle body support device at one support station is located at the lower limit position, which makes it convenient for operators to enter the vehicle body 3 to carry out work.
