Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, and more specifically, to a lifting device and a monorail transit production line. Background Technology

[0002] In the field of rail transit technology, such as monorail systems, the manufacturing, maintenance, and repair processes of vehicles are quite complex. Car bodies require lifting in various scenarios or under various working conditions. For example, in some scenarios, it is necessary to lift a car body with only the main frame to a support structure for work underneath or inside the car body. In other scenarios, it is necessary to lift a car body with bogies connected underneath or to be connected to bogies. Currently, the common practice is to design different specialized lifting tools for different operating scenarios, which can meet the lifting needs of the car body in various scenarios. However, this requires multiple sets of lifting tools, resulting in high costs and a large amount of storage space. Utility Model Content

[0014] In the lifting device and monorail transit production line of this utility model, a support beam is arranged under the car body. The support beam has two first lifting interfaces spaced apart in the width direction of the car body. The distance between the two first lifting interfaces is greater than the width of the car body. The lifting equipment can lift the support beam by connecting to the two first lifting interfaces. When a support seat is used as the support structure between the support beam and the car body (the first use case of the lifting device), the upper end of the support seat is used to connect to a first set structure on the car body chassis for mounting the bogie. The lifting device can be arranged under the car body by occupying at least part of the arrangement space of the bogie. Thus, by lifting the support beam, the car body can be lifted in the case where the bogie does not need to be arranged. In this case, it is beneficial to reduce the weight of the car body. When lifting the car body at a low center of gravity, the lifting stability is ensured. This design fully utilizes the load-bearing capacity of the original first-set structure of the car body chassis, avoiding the need for additional structural reinforcement. It also balances the stability of the car body lifting and the effectiveness of force transmission. When using columns as the support structure between the support beam and the car body (the second use case of the lifting device), the positions of the support beam and column are offset from the positions of the bogies below the car body. This allows for lifting of the car body even when bogies are located below it or when bogies are required. Furthermore, it utilizes the superior force transmission performance of the second-set structure at the car body chassis position, avoiding the need for additional structural reinforcement while maintaining the stability of the car body lifting and the effectiveness of force transmission. Overall, in this utility model, one set of lifting equipment can be adapted to various working conditions such as lifting only the car body or lifting the car body and bogie as a whole. This utility model adopts a modular design scheme, which allows the support base and column to be selectively and detachably connected to the support beam. The lifting equipment has high applicability in multiple scenarios and effectively reduces the cost of manufacturing, warehousing and managing multiple sets of special lifting equipment.

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

[0021] like Figure 1 , Figure 4 and Figure 7 As shown, this utility model provides a lifting device, which includes a support beam 1, a support base 21 and a column 22; the support beam 1 is arranged below the vehicle body 73 and is set along the width direction of the vehicle, and the support beam 1 is provided with two first hanging interfaces 12 that are spaced apart in its length direction, the distance between the two first hanging interfaces 12 is greater than the width of the vehicle body 73, and the two first hanging interfaces 12 are used for hanging the support beam 1; The support base 21 and the column 22 are used to be selectively and detachably connected to the support beam 1; When the support seat 21 is connected to the support beam 1, the two support seats 21 are spaced apart in the width direction of the vehicle body 73, and the upper end of the support seat 21 is used to connect with the first setting structure 731 at the chassis of the vehicle body 73 for mounting the bogie 74. When the column 22 is connected to the support beam 1, the two columns 22 are spaced apart in the width direction of the vehicle body 73. The upper end of the column 22 is used to connect with the second set structure 732 at the chassis of the vehicle body 73. The arrangement positions of the support beam 1 and the column 22 are offset from the arrangement position of the bogie 74 below the vehicle body 73.

[0022] In this manual, when hoisting the vehicle body 73, the length direction of the support beam 1 is consistent with the width direction of the vehicle body 73, both being the X-axis direction in the figure. The width direction of the support beam 1 is consistent with the length direction of the vehicle body 73, both being the Y-axis direction in the figure. The height direction of the column 22, the height direction of the support seat 21, and the height direction of the support beam 1 are consistent with the height direction of the vehicle body 73, all being the Z-axis direction in the figure.

[0023] When hoisting the car body 73, multiple support beams 1 can be arranged along the length of the car body 73. The hoisting equipment connects to two first hanging interfaces 12 on the support beams 1 respectively to hoist the support beams 1, thereby hoisting the car body 73 through multiple support beams 1 and their connected columns 22 or support seats 21.

[0024] It should be noted that the hoisting equipment is usually located above the vehicle body 73, and the way it is connected to the first hoisting interface 12 is not limited. It can be connected to the first hoisting interface 12 through a flexible structure or a rigid structure, which will be illustrated later.

[0025] like Figure 7 As shown, when the lifting device of this utility model uses the support base 21 as the support structure between the support beam 1 and the vehicle body 73 (hereinafter referred to as the first usage of the lifting device), since the first setting structure 731 is used to install the bogie 74, the chassis has better structural performance at the first setting structure 731 because the vehicle body 73 needs to transfer weight through the bogie 74. The upper end of the support base 21 is connected to the first setting structure 731 at the chassis of the vehicle body 73 for installing the bogie 74, which can ensure the reliability of the support base 21 in supporting the vehicle body 73. In this case, the vehicle body 73 can be lifted by the lifting device to operate below the vehicle body 73, or the vehicle body 73 can be transported to, for example, the first preset work position.

[0026] It should be noted that the interface of the first setting structure 731 for connecting with the support base 21 can be the original interface of the component used to install the bogie 74, or it can be a redesigned interface. The redesigned interface does not affect the installation of the bogie 74.

[0027] In some scenarios, the first setting structure 731 is a spring mounting seat, which is used to install the shock-absorbing spring 745 of the bogie 74, such as an air spring. The interface of the first setting structure 731 for connecting with the support seat 21 can be a vertical connecting hole, that is, the top of the support seat 21 is connected to the spring mounting seat through a vertical connector, such as a pin or bolt. In some scenarios, the car body 73 is lifted to the first preset work position by a lifting device. The first preset work position is provided with a first support fixture, which is used to support the car body 73. For example, it is connected to the anti-diving torsion bar seat 733 at the bottom of the car body 73. The lower end of the anti-diving torsion bar seat 733 is lower than the position of the spring mounting seat in the vertical direction. The first support fixture supports the car body 73 by supporting the lower end of the anti-diving torsion bar seat 733. The first support fixture can be provided with a plug-in groove, and the lower end of the anti-diving torsion bar seat 733 forms a plug-in post, which is inserted into the plug-in groove.

[0028] like Figure 4 and Figure 5 As shown, when the lifting device of this utility model uses the column 22 as the support structure between the support beam 1 and the vehicle body 73 (hereinafter referred to as the second use case of the lifting device), the second setting structure 732 must be positioned on the chassis of the vehicle body 73 to avoid the bogie 74, so as to avoid interference between the column 22 and the bogie 74 after the column 22 and the second setting structure 732 are connected. On this basis, the position and configuration of the second setting structure 732 on the chassis are not limited. It can be constructed by using the inherent interface of the chassis of the vehicle body 73, or it can be specially set according to the connection requirements with the column 22. For example, the second setting structure 732 can be connected to the longitudinal beam of the chassis. While avoiding interference with the bogie 74 under the vehicle body 73, the reliability of the support for the vehicle body 73 can be ensured, and the reliable lifting of the vehicle body 73 can be achieved. In the second use of this lifting device, the car body 73 can be lifted to facilitate the installation of the bogie 74 below the car body 73, or the car body 73 and the bogie 74 connected to it can be hoisted as a whole when the bogie 74 is installed on the car body 73.

[0029] In the lifting device of this utility model, the support beam 1 is arranged below the vehicle body 73. The support beam 1 is provided with two first lifting interfaces 12 spaced apart in the vehicle width direction. The distance between the two first lifting interfaces 12 is greater than the width of the vehicle body 73. The lifting equipment can lift the support beam 1 by connecting to the two first lifting interfaces 12. When the support seat 21 is used as the support structure between the support beam 1 and the vehicle body 73 (the first use case of the lifting device), the upper end of the support seat 21 is used to connect to the first setting structure 731 for mounting the bogie 74 on the chassis of the vehicle body 73. The lifting device can be arranged below the vehicle body 73 by occupying at least part of the arrangement space of the bogie 74. Thus, by lifting the support beam 1, the vehicle body 73 can be lifted in the case where the bogie 74 does not need to be arranged. In this case, it is beneficial to reduce the lifting capacity of the vehicle body 73. The center of gravity of the car body 73 at time 3 ensures the stability of the lifting operation and makes full use of the load-bearing capacity of the original first set structure 731 of the car body 73 chassis, avoiding the need for additional structural reinforcement design, while taking into account the stability of the car body 73 and the effectiveness of force transmission. When the column 22 is used as the support structure between the support beam 1 and the car body 73 (the second use case of the lifting device), the arrangement of the support beam 1 and the column 22 is offset from the arrangement of the bogie 74 under the car body 73. Thus, the car body 73 can be lifted when there is a bogie 74 under the car body 73 or when there is a need for the bogie 74 to be arranged, by suspending the support beam 1. It also takes advantage of the good force transmission performance of the second set structure 732 at the chassis position of the car body 73, avoiding the need for additional structural reinforcement design, while taking into account the stability of the car body 73 and the effectiveness of force transmission. Overall, in this utility model, one set of lifting equipment can be adapted to various working conditions such as lifting only the car body 73 or lifting the car body 73 and the bogie 74 as a whole. This utility model adopts a modular design scheme, which allows the support base 21 and the column 22 to be selectively and detachably connected to the support beam 1. The lifting equipment has high applicability in multiple scenarios and effectively reduces the cost of manufacturing, warehousing and managing multiple sets of special lifting equipment.

[0030] like Figure 4 As shown, in the second use case of the above-mentioned lifting device, that is, when the column 22 is connected to the support beam 1, the support beam 1 can optionally be arranged below the temporary support rail 71 of the vehicle body 73.

[0031] It should be understood that the vertical dimension of the column 22 is greater than that of the support base 21 in the vertical direction. In some scenarios, in the second usage case, a temporary support rail 71 can be arranged in the space between the support beam 1 and the underside of the vehicle body 73.

[0032] In this specification, the following will use the example of the lifting tool also being used to lift the temporary support rail 71 to illustrate the content of this utility model.

[0033] In this case, the support beam 1 is arranged below the temporary support rail 71 of the car body 73, and the two columns 22 are arranged at intervals below the car body 73 in the width direction of the car body 73. The lower ends of the columns 22 are connected to the support beam 1, and the upper ends are connected to the second set structure 732 at the chassis of the car body 73. In this case, the lifting device of this utility model avoids interference with the bogie 74 (including the traveling wheels 742, guide wheels 743, and balance wheels 746, etc.) and the temporary support rail 71 during the lifting process. It can be used to lift the car body 73 without the bogie 74 connected, as well as the car body 73 connected to the bogie 74. For example, in some scenarios, this lifting device can also be used to lift the car body 73, the temporary support rail 71 under the car body 73, and the bogie 74 connected to the car body 73 as a whole to the running track and connect it with the running track. This makes it convenient for the car body 73 to be transferred to the running track (the running track can be an experimental track or a track of a rail transit system) after the lifting device is disassembled.

[0034] like Figure 5 As shown, in the second use case of the above-mentioned lifting device (that is, when the column 22 is connected to the support beam 1), the lifting device may also be used to lift the temporary support rail 71; the support beam 1 and the temporary support rail 71 are connected at an upper limit in at least one of the length direction and the width direction of the vehicle body 73.

[0035] The method of limiting the connection between the support beam 1 and the temporary support rail 71 in at least one direction is not a restriction. When the two are connected in a limiting manner, it is beneficial to ensure the stability of the relative position of the temporary support rail 71 and the support beam 1, and improve the stability of the lifting device in lifting the car body 73, the temporary support rail 71 and the connected components.

[0036] like Figure 5 As shown, in the second use case of the above-mentioned lifting device (that is, when the column 22 is connected to the support beam 1), the lifting device further includes a first limiting structure 81. The two first limiting structures 81 are located on both sides of the temporary support rail 71 and are detachably connected to the support beam 1. The first limiting structure 81 is used to abut against the side wall of the temporary support rail 71 in the vehicle width direction.

[0037] Specifically, the support beam 1 is provided with a connection interface for connecting with the first limiting structure 81. The first limiting structure 81 is adjustable in position in the vehicle width direction on the support beam 1. For example, the first limiting structure 81 and the support beam 1 are connected by a connector, and the through hole on the support beam 1 or the first limiting structure 81 for the connector to pass through is an elongated hole extending in the vehicle width direction.

[0038] In this case, when arranging the lifting equipment, the support beam 1 can be placed under the vehicle body 73 first, and the support beam 1 can be hoisted by the hoisting equipment. After the column 22 is connected to the second setting structure 732, the first limiting structure 81 can be connected to the support beam 1. Of course, at least one first limiting structure 81 can be initially connected to the support beam 1 first, and then the position of the first limiting structure 81 can be adjusted as needed.

[0039] The vertical dimension of the first limiting structure 81 is smaller than that of the support base 21 in the vertical direction. Therefore, in some scenarios, such as the first use of the lifting device, the first limiting structure 81 can be retained on the support beam 1 unless necessary, which can reduce the frequency of the first limiting structure 81 being removed from the support beam 1.

[0040] like Figure 5 As shown, in the second use case of the above-mentioned lifting device (that is, when the column 22 is connected to the support beam 1), the bottom end of the temporary support rail 71 is further fixedly connected to a second limiting structure 82. The two second limiting structures 82 are distributed at intervals in the vehicle length direction. The support beam 1 is accommodated between the two second limiting structures 82. The side wall of the support beam 1 in the vehicle length direction is used to abut against the second limiting structure 82.

[0041] The second limiting structure 82 can be welded to the temporary support rail 71. When arranging the lifting equipment, the support beam 1 can be placed under the car body 73 and placed between the two second limiting structures 82 to achieve the relative positioning of the support beam 1 and the car body 73 in the length direction of the car.

[0042] It should be noted that, in the above embodiment, a temporary support 72 can be connected below the temporary support rail 71, and the temporary support rail 71 is supported on the ground by the temporary support 72, thereby facilitating the arrangement of the support beam 1 from below the temporary support rail 71. The hoisting equipment can simultaneously hoist the car body 73, the temporary support rail 71, the temporary support 72, and the bogie 74 using a lifting device.

[0043] like Figure 6 As shown, in the second use case of the above-mentioned lifting device (that is, when the column 22 is connected to the support beam 1), a temporary limiting frame 83 is optionally provided between the temporary support rail 71 and the car body 73, and the temporary limiting frame 83 is detachably connected to the temporary support rail 71 and the car body 73 respectively.

[0044] For example, the temporary limiting frame 83 is located at one end of the car body 73 and is detachably connected to the temporary support rail 71 and the car body 73 respectively. Thus, the connection between the temporary support rail 71 and the car body 73 can be realized by using the temporary limiting frame 83. The structure is simple and highly practical.

[0045] like Figure 6As shown, in the second use case of the above-mentioned lifting device (that is, when the column 22 is connected to the support beam 1), the temporary support rail 71 may optionally be provided with at least one of the following: guide wheel limit seat 75, balance wheel limit seat 76, and frame limit seat 77. The guide wheel limit seat 75 abuts against the guide wheel 743 of the bogie 74 in the length direction, the balance wheel limit seat 76 abuts against the balance wheel 746 of the bogie 74 in the length direction, and the frame limit seat 77 is connected to the frame 741 of the bogie 74 by a binding strap 78.

[0046] In the above embodiments, optionally, at least one of the support base 21 and the column 22 is a lifting structure.

[0047] It should be noted that the heights of both the column 22 and the support base 21 can be fixed, or they can be adjustable. When the heights of both the support base 21 and the column 22 are adjustable, the methods of adjusting their heights can be different.

[0048] In this way, the height adjustment of the support seat 21 can meet the different distance requirements between the chassis of the vehicle body 73 and the ground. When the height of the column 22 is adjustable, the height of the column 22 can be adjusted to a suitable position so that the height of the column 22 can adapt to the vertical position deviation of the second setting structure 732 at the chassis of the vehicle body 73. This position deviation may be caused by the processing error of the vehicle body 73 and the temporary support rail 71. When the running wheels 742 of the bogie 74 need to be inflated, the second setting structure 732 may also have this vertical position deviation before and after inflation. The height adjustment of the column 22 allows the column 22 to better meet the height requirements for connection with the second setting structure 732.

[0049] like Figure 1 and Figure 5 As shown, in a further optional embodiment of the column 22, the column 22 includes a fixed column 221, a lifting column 222, and a connector 223. The lower end of the fixed column 221 is detachably connected to the support beam 1, and the upper end is provided with a first receiving cavity. The lower end of the lifting column 222 is received in the first receiving cavity and is threadedly connected to the fixed column 221. The upper end of the connector 223 is connected to the second setting structure 732, and the lower end of the connector 223 is provided with a second receiving cavity. The upper end of the lifting column 222 is received in the second receiving cavity. The upper end of the lifting column 222 is threadedly connected to the connector 223 (not shown in this diagram) so that the distance between the connector 223 and the fixed column 221 can be adjusted by rotating the lifting column 222 about its axis relative to the fixed column 221 and the connector 223 respectively.

[0050] Specifically, the lifting column 222 is a double-ended stud. In some scenarios, when viewed along the negative Z-axis, as the lifting column 222 rotates clockwise around its axis, the length of the lifting column 222 housed in the first receiving cavity becomes shorter, and the length of the lifting column 222 housed in the second receiving cavity also becomes shorter, thereby increasing the distance between the connector 223 and the fixed column 221. When viewed along the negative Z-axis, as the lifting column 222 rotates counterclockwise around its axis, the length of the lifting column 222 housed in the first receiving cavity becomes longer, and the length of the lifting column 222 housed in the second receiving cavity also becomes longer, thereby decreasing the distance between the connector 223 and the fixed column 221.

[0051] It should be noted that in this case, nuts for position locking can be provided on the lifting column 222. For example, two nuts are threadedly connected to the lifting column 222 and abut against the fixed column 221 and the connector 223 respectively.

[0052] like Figure 1 and Figure 5 As shown, unlike the above-mentioned scheme where the upper end of the lifting column 222 is threadedly connected to the connector 223, in some scenarios, the upper end of the lifting column 222 and the connector 223 are rotatably connected around the axis of the lifting column 222.

[0053] Specifically, the upper end of the lifting column 222 is inserted into the second accommodating cavity. There is no threaded connection structure between the lifting column 222 and the second accommodating cavity, and the two can only rotate relative to the axis of the lifting column 222.

[0054] In this case, the overall height of the column 22 can be adjusted by rotating the lifting column 222 relative to the fixed column 221, and the position of the connector 223 in the horizontal plane can be adjusted by rotating the connector 223 relative to the lifting column 222, so that it can be easily connected to the second setting structure 732.

[0055] In this case, a locking structure is usually provided between the lifting column 222 and the connector 223. The locking structure is used to lock or unlock the relative position of the connector 223 and the lifting column 222.

[0056] In some scenarios, the locking structure includes a set screw that passes through the wall of the second receiving cavity and abuts against the lifting column 222. The lifting column 222 may be provided with an annular groove for receiving the set screw, which will not be described in detail here.

[0057] In some scenarios, the lifting column 222 and the connector 223 can be respectively set on the connecting plate extending in the horizontal plane, and the two connecting plates are connected by vertical fasteners. At least one of the connecting plates has a through hole for fasteners to pass through, which is an oblong hole coaxial with the lifting column 222.

[0058] like Figure 5As shown in the above embodiment, optionally, the upper end of the column 22 is provided with a receiving groove structure 225, the second setting structure 732 is housed in the receiving groove structure 225, the second setting structure 732 is inserted into the receiving groove structure 225, and the groove wall of the receiving groove structure 225 is used to abut against the second setting structure 732.

[0059] Specifically, the upper end of the connector 223 is provided with a receiving groove structure 225. When the second setting structure 732 is inserted into the receiving groove structure 225, the bottom of the receiving groove structure 225 can abut against the second setting structure 732, and the groove wall of the receiving groove structure 225 can abut against the second setting structure 732, thus restricting the relative rotation of the two.

[0060] The large surface of the second setting structure 732 can be perpendicular to the vehicle width direction, and the receiving groove structure 225 can be a C-shaped groove. In actual manufacturing, the C-shaped groove can be made by bending sheet metal.

[0061] The receiving groove structure 225 and the second setting structure 732 are connected by a connector, which can be a vertical connector or a horizontal connector. The horizontal connector can be a pin or a screw.

[0062] Thus, during the connection of the column 22, the receiving groove structure 225 can play a guiding and positioning role, facilitating the quick connection of the column 22 and the second setting structure 732. Furthermore, when the column 22 has the aforementioned lifting column 222 and the height of the lifting column 222 is adjusted by rotating around its axis, the groove wall of the receiving groove structure 225 can abut against the second setting structure 732, thereby restricting the degree of freedom of the connector 223 to rotate around the axis of the lifting column 222. When the lifting column 222 rotates, the connector 223 can only move upward or downward until the connector 223 moves to the required height to facilitate connection with or separation from the second setting structure 732.

[0063] It should be noted that elastic pads can be provided on the bottom and / or walls of the receiving groove structure 225 to ensure the contact performance between the two, which will not be described in detail here.

[0064] like Figure 1 As shown in the above embodiment, optionally, at least one of the support base 21 and the column 22 is connected to the support beam 1 in an adjustable position in the vehicle width direction.

[0065] Specifically, the lower end of the fixing post 221 of the column 22 is provided with a connecting plate 224, which is connected to the support beam 1 through a connecting frame. The support beam 1 is provided with a plurality of first connecting holes 101, which are connected to the connecting plate 224 through the first connecting holes 101.

[0066] In some scenarios, the first connecting hole 101 is an elongated hole extending in the vehicle width direction, and the top of the support beam 1 is provided with a connecting edge, on which the first connecting hole 101 is located.

[0067] The position of the support 21 is adjustable in a similar way, and will not be described in detail here.

[0068] In this way, the position of the column 22 or the support 21 in the vehicle width direction can be adjusted within a certain range. The position can be adjusted as needed to meet the position adjustment requirements of the column 22 or the support 21 due to processing and assembly errors, reduce the possibility of stress concentration of the column 22 or the support 21, thereby improving the stress condition when the spreader lifts the vehicle body 73 and extending the service life of the spreader.

[0069] like Figure 1 As shown, in the above embodiment, optionally, the lifting device also includes a lifting beam 3 and connecting ropes 4. The lifting beam 3 is arranged above the vehicle body 73. The two connecting ropes 4 are arranged on both sides of the vehicle body 73 along the length direction of the support beam 1. The upper ends are connected to the lifting beam 3, and the lower ends are connected to the two first hanging interfaces 12 of the support beam 1. The top of the lifting beam 3 is provided with multiple second hanging interfaces 32 in the vehicle width direction. The second hanging interfaces 32 are used for hanging the lifting beam 3.

[0070] Specifically, in this embodiment, the hoisting equipment is usually located above the hoisting beam 3. The way it is connected to the second hoisting interface 32 is not limited. It can be connected to the second hoisting interface 32 through a flexible structure or a rigid structure. The hoisting equipment hoists the hoisting beam 3 by connecting to the second hoisting interface 32. The hoisting beam 3 is connected to the two first hoisting interfaces 12 of the support beam 1 by two connecting ropes 4, thereby hoisting the support beam 1. The support beam 1 supports the vehicle body 73 through the column 22.

[0071] Specifically, the lifting beam 3 is provided with a first connecting seat. Two first connecting seats are distributed at intervals along the length of the lifting beam 3. The distance between the two first connecting seats is greater than the width of the vehicle body 73. The upper ends of the two connecting ropes 4 are respectively connected to the two first connecting seats of the lifting beam 3, and the lower ends are respectively connected to the two first hanging interfaces 12 of the support beam 1.

[0072] In this embodiment, the lifting beam 3 is arranged above the vehicle body 73. The second hanging interface 32 on the lifting beam 3 is used for hanging the lifting beam 3. Two connecting ropes 4 are arranged on both sides of the vehicle body 73 along the length direction of the support beam 1. The upper ends are connected to the two first connecting seats of the lifting beam 3, and the lower ends are connected to the two first hanging interfaces 12 of the support beam 1. The two connecting ropes 4 can avoid contact with the vehicle body 73. The weight of the vehicle body 73 is transferred to the support beam 1 through the column 22, and then transferred to the lifting beam 3 by the connecting ropes 4 connected to the support beam 1. Finally, it is transferred to the hoisting equipment through the second hanging interface 32 of the lifting beam 3. Thus, the hoisting equipment can hoist the lifting beam 3, the connecting ropes 4, the support beam 1, the column 22 and the vehicle body 73 by hanging the second hanging interface 32. When the vehicle body 73 is hoisted, the hoisting force on the vehicle body 73 is relatively uniform, which helps to avoid the vehicle body 73 tilting, swinging or rotating during the hoisting process, thereby reducing the risk of accidents.

[0073] like Figure 1 As shown, optionally, the lifting device also includes lifting ropes 5 and lifting rings 6. The lifting rings 6 are located above the lifting beam 3. The upper ends of the multiple lifting ropes 5 are respectively connected to the lifting rings 6, and the lower ends of the multiple lifting ropes 5 are respectively connected to multiple second hanging interfaces 32.

[0074] like Figure 1 As shown, two second hanging interfaces 32 are provided on the lifting beam 3 in the Y-axis direction. The two second hanging interfaces 32 are symmetrically arranged in the Y-axis direction. The two columns 22 are symmetrically arranged in the Y-axis direction. The two first hanging interfaces 12 are symmetrically arranged in the Y-axis direction. The symmetrical planes of the two second hanging interfaces 32, the symmetrical planes of the two columns 22, and the symmetrical planes of the two first hanging interfaces 12 are coplanar. When the vehicle body 73 is suspended by the lifting device, this symmetrical plane coincides with the center plane of the vehicle body 73 in the vehicle width direction.

[0075] The lifting ring 6 serves as the main interface with the lifting equipment. It is connected to multiple second lifting interfaces 32 via multiple lifting ropes 5. The lifting ring 6 is connected to the lifting beam 3 via multiple lifting ropes 5. The lifting equipment can distribute the lifting force transmitted by the lifting ring 6 to the entire lifting beam 3 by hanging it on the lifting ring 6 of multiple lifting devices and using multiple lifting ropes 5. This can reduce the structural complexity of the connection between the lifting equipment and the lifting devices.

[0076] like Figure 3As shown, in some scenarios, the lifting beam 3 includes an upper connecting seat 33 and a lifting beam body 31. The upper connecting seat 33 is integrally connected to the top of the lifting beam body 31 and extends along the length of the lifting beam 3. Multiple second hanging interfaces 32 are provided on the upper connecting seat 33. The provision of the upper connecting seat 33 helps to enhance the overall structural performance of the lifting beam 3 and improve its bending resistance. The lifting beam body 31 can be a box-shaped structure. An intermediate plate can be provided inside the box-shaped structure. The intermediate plate is welded to the upper plate and the lower plate of the box-shaped structure, and the position of the intermediate plate corresponds to the position of the upper connecting seat 33.

[0077] like Figure 3 As shown in the above embodiment, optionally, the second hanging interface 32 includes a rotatably configured first connecting ring 301. The rotation axis of the hanging ring 6 and the rotation axis of the first connecting ring 301 extend in the length direction of the vehicle body 73. The two ends of the hanging rope 5 are respectively provided with a first loop structure 51. The first loop structure 51 at the upper end of the hanging rope 5 is movably connected to the hanging ring 6 through interlocking, and the first loop structure 51 at the lower end of the hanging rope 5 is movably connected to the first connecting ring 301 through interlocking. Specifically, the first connecting ring 301 is connected to the upper connecting seat 33 via a rotating shaft that extends along the length of the vehicle body 73, i.e., along the X-axis direction in the figure. The first connecting ring 301 provides an interface for connecting with the first loop structure 51 of the suspension rope 5. The rotation of the first connecting ring 301 around its rotating shaft, combined with the relative movement of the first loop structure 51 of the suspension rope 5 and the first connecting ring 301, satisfies the adjustment requirements of the relative posture of the lifting ring 6 and the lifting beam 3.

[0078] The lifting ring 6 and the first ring structure 51 at the upper end of the lifting rope 5 are interlocked and movably connected to each other to form a chain structure. The lifting ring 6 and the first ring structure 51 can move relative to each other according to the force applied.

[0079] Thus, during the process of suspending the vehicle body 73 by the hoisting equipment, the position and angle of the hoisting rope 5 relative to the hoisting ring 6 and the position and angle of the hoisting rope 5 relative to the hoisting beam 3 can be smoothly and adaptively adjusted according to the force conditions. This is also conducive to the hoisting ring 6, the hoisting rope 5 and the hoisting beam 3 forming a triangular hoisting force transmission system, which helps to ensure the positional stability of the vehicle body 73 during the hoisting process.

[0080] like Figure 1 and Figure 2As shown in the above embodiment, optionally, the first hanging interface 12 includes a first connecting shaft 122 extending in the vehicle length direction, the lower end of the hanging beam 3 is rotatably provided with a second connecting ring 302, the rotation axis of the second connecting ring 302 extends in the vehicle length direction of the vehicle body 73, the two ends of the connecting rope 4 are respectively provided with a second ring structure 41, the second ring structure 41 at the upper end of the connecting rope 4 and the second connecting ring 302 are interlocked and movably connected, and the second ring structure 41 at the lower end of the connecting rope 4 is sleeved on the first connecting shaft 122.

[0081] The support beam 1 may further include a support beam body 11. The first hanging interface 12 includes a lug plate 121, a first connecting shaft 122, and a first reinforcing plate 123. The lug plate 121 is vertically arranged at one end of the support beam body 11 along its length and is welded to the end plate of the support beam body 11. The two lug plates 121 are arranged opposite each other and spaced apart from the edge of the end face along the vehicle length direction. The first connecting shaft 122 is connected to the two lug plates 121 respectively. The two first reinforcing plates 123 are located on opposite sides of the two lug plates 121 respectively. The first reinforcing plates 123 are welded to the corresponding lug plate 121, the end plate of the support beam body 11, and the side plate of the support beam body 11 respectively. This design enables the connection between the first hanging interface 12 and the support beam body 11 to achieve good local stiffness.

[0082] Specifically, a hanging plate can be provided at the bottom end of the hanging beam body 31 of the hanging beam 3. The second connecting ring 302 is connected to the hanging plate. The axis of the second connecting ring 302 extends in the length direction of the hanging beam 3. The hanging beam 3 may also include a second reinforcing plate. Two second reinforcing plates are respectively connected to the hanging plate on both sides in the X-axis direction. The second reinforcing plates are triangular and are welded to the hanging plate and the bottom plate of the hanging beam body 31 respectively. The pin is located between the two second reinforcing plates distributed in the Y-axis direction.

[0083] Thus, the second connecting ring 302, as an independent and rotatable connector, becomes the main stress point and wear point, providing sufficient space for the connection and movement of the second loop structure 41 of the connecting rope 4. This helps reduce the contact stress between the connecting rope 4 and the lifting beam 3, improves the stress condition of the lifting rope 5, and extends the service life of the lifting device. The second loop structure 41 at the lower end of the connecting rope 4 is sleeved on the first connecting shaft 122, and its structure is relatively simple. Overall, this arrangement allows the connecting rope 4 to swing freely relative to the lifting beam 3 and the support beam 1 in the YZ plane according to the stress condition, adapting to the lifting conditions. The second loop structure 41 is rotatable with the first connecting shaft 122 or the second connecting ring 302, and the friction is mainly rolling or sliding friction. Compared with the connecting rope 4 being directly knotted or rubbing against metal edges, this helps reduce wear. This embodiment helps avoid unpredictable twisting and scratching, extends the service life of the connecting rope 4 and its connecting structure, and reduces maintenance frequency and cost.

[0084] like Figure 2 and Figure 7 As shown in the above embodiment, optionally, the support base 21 includes a base plate 211, a top plate 212 and an intermediate support structure. The lower end of the intermediate support structure is connected to the base plate 211 and the upper end is connected to the top plate 212. The base plate 211 is detachable from the support beam 1 and the top plate 212 is detachably connected to the first setting structure 731.

[0085] Specifically, the intermediate support structure includes multiple vertical plates, including a first vertical plate 213 and a second vertical plate 214. The first vertical plate 213 extends along the length of the support beam 1 and is welded to the base plate 211 and the top plate 212 at its upper and lower ends, respectively. The second vertical plate 214 extends along the length of the vehicle body 73 and is welded to the base plate 211, the top plate 212, and the first vertical plate 213, respectively. At least one side of the second vertical plate 214 on the base plate 211 is provided with a connection hole for connecting to the support beam 1, and at least one side of the second vertical plate 214 on the top plate 212 is provided with a connection hole for connecting to the first setting structure 731.

[0086] Thus, the first vertical plate 213 and the second vertical plate 214 form a high-strength, high-rigidity three-dimensional support frame. The first vertical plate 213 provides the main compressive strength and effectively transmits the vertical load, while the second vertical plate 214 acts as a reinforcing rib, which is conducive to the lightweight design of the intermediate support structure and facilitates the arrangement of the connection holes on the base plate 211 and the top plate 212. The structure is simple and highly practical.

[0087] In contrast to the above-mentioned intermediate support structure design, the intermediate support structure can optionally be a retractable multi-segment structure, with the upper segment connected to the top plate 212 and the lower segment connected to the base plate 211. This will not be described in detail here.

[0088] Another embodiment of this utility model provides a monorail transit production line, including hoisting equipment and lifting devices as described in the above embodiment. Multiple lifting devices are distributed along the length of the vehicle body 73, and the support beam 1 of the lifting device is suspended from the hoisting equipment through two first hanging structures provided thereon. The lifting device is connected to the first setting structure 731 of the vehicle body 73 via its support base 21, or the lifting device is connected to the second setting structure 732 of the vehicle body 73 via its column 22.

[0089] Some aspects of the monorail transit production line have already been described above. The monorail transit production line is capable of operating in various conditions. In some scenarios, such as the first scenario, where bogie 74 is not required, the car body 73 can be suspended by the support seat 21. In some scenarios, the monorail transit production line includes a first support fixture for supporting the car body 73, for example, by connecting to the anti-head-sway torsion bar seat 733 at the bottom of the car body 73. The lower end of the anti-head-sway torsion bar seat 733 is lower than the position of the spring mounting seat in the vertical direction. The first support fixture supports the car body 73 by supporting the lower end of the anti-head-sway torsion bar seat 733. The first support fixture can be provided with a plug-in slot, and the lower end of the anti-head-sway torsion bar seat 733 forms a plug-in post, which is inserted into the plug-in slot. In this scenario, the lifting device can be the support seat 21, which is connected to the first set structure 731 to lift the car body 73 to the connection with the first support fixture.

[0090] For example, in the second working condition, the temporary support rail 71, the car body 73 and the bogie 74 need to be hoisted as a whole so that the temporary support rail 71 can be connected to another running track, so that the car body 73 can be transferred between the temporary support rail 71 and the running track through the bogie 74.

[0091] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
