Abstract
Description
Technical Field
[0001] This utility model relates to the field of maglev vehicle technology, and more specifically, to a clamp-type lifting beam for lifting and transporting the body-in-white of a maglev vehicle. Background Technology
[0002] Compared to traditional urban rail vehicles, embedded low-speed maglev vehicles lack lifting points in their body-in-white, requiring them to be supported and operated only by being lifted from below. This design difference presents the following problems:
[0003] When it is necessary to install or transport the body-in-white of a maglev vehicle, since there are no lifting points on the body-in-white, it is impossible to lift it to the target location. Using equipment such as lifters to lift the body-in-white from below can only transport it to the vicinity of the target location. It is difficult to transfer it from the lifters or other equipment to the target location. Other transfer equipment must be used in conjunction. As a result, the installation and transportation of the body-in-white is very inconvenient, the whole process is complicated, the work efficiency is low, and the safety is low. Utility Model Content
[0004] The present invention aims to provide a clamp-type lifting beam for lifting and transporting the body-in-white of a maglev vehicle, in order to solve the problem that there is a lack of lifting devices suitable for the body-in-white of maglev vehicles in the prior art, since there are no lifting points on the body-in-white of the maglev vehicle.
[0005] This utility model is achieved using the following technical solution:
[0006] This utility model provides a clamp-type lifting beam for lifting and transporting the body-in-white of a maglev vehicle, including a portal frame with lifting points on the portal frame;
[0007] The portal frame includes a crossbeam and columns. The columns are connected to both ends of the crossbeam. One end of the column is connected to the crossbeam, and the other end of the column is connected to a lifting arm.
[0008] The lifting arm is rotatably connected to the column. After the lifting arm is rotated into position, a fixing component is connected between the lifting arm and the column. The lifting arm is used to support the bottom of the white body of the maglev vehicle.
[0009] The other end of the column is connected to the lifting arm, and the lifting arm is rotatably connected to the column. The lifting arm can rotate into the portal frame to support the white body of the maglev vehicle, or it can rotate out of the portal frame to avoid interference with the white body of the maglev vehicle during hoisting operations.
[0010] In operation, overhead cranes and other hoisting equipment can be connected to the lifting points of the portal frame via slings. The lifting boom is then rotated outside the portal frame and secured with fasteners. The clamp-type lifting beam is then hoisted to the lifting position, ensuring the portal frame is on the outside of the maglev vehicle body, with the two columns positioned on either side of the vehicle body. The fasteners are then removed, and the lifting boom is rotated inside the portal frame, supporting the maglev vehicle's body at the designated location below. The lifting boom is then secured with fasteners and adjusted to the lifting position. Following this method, the two clamp-type lifting beams support the front and rear of the maglev vehicle's body. By then, the overhead cranes and other hoisting equipment can be activated to smoothly and safely hoist and transport the maglev vehicle's body.
[0011] This utility model's clamp-type lifting beam is suitable for the body-in-white of maglev vehicles. The lifting equipment connects to the lifting points on the portal frame, hoisting the portal frame to the hoisting position so that it is positioned outside the embedded low-speed maglev vehicle body-in-white. Then, by rotating the lifting arm, it supports the bottom of the maglev vehicle body-in-white. The maglev vehicle body-in-white is then hoisted and transported using the lifting equipment. The operation is simple and convenient, improving work efficiency and enhancing the convenience and safety of hoisting and transportation. It overcomes the problem of the lack of suitable lifting devices for maglev vehicle body-in-white in existing technologies.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0045] Example 1
[0046] like Figures 1-4 As shown in the figure, this embodiment proposes a clamp-type lifting beam for lifting and transporting the body-in-white of a maglev vehicle, including a portal frame 1. The portal frame 1 includes two columns 102 and a crossbeam 101. The upper ends of the two columns 102 are respectively connected to the two ends of the crossbeam 101. The columns 102 and the crossbeam 101 are fixedly connected, and the fixed connection method includes, but is not limited to, welding, bolting, etc. The portal frame 1 is provided with lifting points for connecting to lifting equipment.
[0047] Each of the columns 102 is connected to a lifting arm 2 at its lower end. The lifting arm 2 is rotatably connected to the column 102. The lifting arm 2 can be rotated into the portal frame 1 to support the white body 6 of the maglev vehicle, or it can be rotated out of the portal frame 1 to avoid interference with the white body 6 of the maglev vehicle during hoisting operations.
[0048] After the lifting boom 2 is rotated into position, a fixing member is installed between the lifting boom 2 and the column 102 to fix the lifting boom 2. The fixing member is detachably connected between the lifting boom 2 and the column 102. The fixing member is easy to install and remove, thereby facilitating the adjustment and change of the position of the lifting boom 2 and the fixing of the lifting boom 2.
[0049] In the lifting state, the lifting arm 2 is located inside the portal frame 1, and the maglev vehicle body-in-white 6 is located inside the portal frame 1, with its bottom supported by two symmetrical lifting arms 2. The lifting arms 2 are preferably perpendicular to the column 102 to support the maglev vehicle body-in-white 6, but are not limited to being perpendicular to the column 102, as long as the lifting arms 2 and the bottom of the maglev vehicle body-in-white 6 cooperate to provide stable support. Since the lifting equipment is connected to the lifting points on the portal frame 1, after support is completed, the portal frame 1, lifting arms 2, and maglev vehicle body-in-white 6 are lifted as a whole by the lifting equipment, and the maglev vehicle body-in-white 6 is hoisted to the target position. Then, the fixing components are removed, allowing the lifting arms 2 to rotate freely. The lifting arms 2 are rotated outside the portal frame 1 and fixed. Finally, the portal frame 1 and the connected lifting arms 2 are hoisted away by the lifting equipment.
[0050] The lifting arm 2 is equipped with a support plate 3. When the lifting arm 2 rotates into the portal frame 1, the support plate 3 supports the white body 6 of the maglev vehicle above.
[0051] In this embodiment, the support plate 3 is fixedly connected to the lifting arm 2.
[0052] The support structure is not limited to the support plate 3; other support structures that can support the white body 6 of the maglev vehicle may also be used.
[0053] In this embodiment, the lifting arm 2 is connected to the column 102 via a rotating pin 4 to achieve rotation of the lifting arm 2. The lifting arm 2 has a first pin hole 201, and the column 102 has a rotating hole. The first pin hole 201 is aligned with the rotating hole, and the rotating pin 4 passes through the first pin hole 201 and the rotating hole.
[0054] In this embodiment, the lifting arm 2 is connected to the column 102 via a fixing pin 5 (i.e., the fixing member) to fix the lifting arm 2. The lifting arm 2 is also provided with a second pin hole 202 and a third pin hole 203. The column 102 is provided with a fixing hole. The first pin hole 201, the second pin hole 202, and the third pin hole 203 are arranged in a triangle, that is, the three pin holes are located at the vertices of the triangle. The lifting arm 2 can be aligned with the second pin hole 202 or the third pin hole 203 by rotating the fixing hole.
[0055] When the lifting arm 2 is rotated to be perpendicular to the portal frame 1, the second pin hole 202 is exactly aligned with the fixing hole. At this time, the fixing pin 5 is passed through the second pin hole 202 and the fixing hole, and the lifting arm 2 is connected to the column 102 through the fixing pin 5, so that the lifting arm 2 can be fixed in this position.
[0056] When the lifting arm 2 is rotated outside the portal frame 1 and hangs obliquely downward, the third pin hole 203 is aligned with the fixing hole. At this time, the fixing pin 5 is passed through the third pin hole 203 and the fixing hole, and the lifting arm 2 is connected to the column 102 through the fixing pin 5. The lifting arm 2 can be fixed in this position. Fixing the lifting arm 2 in this position in the preparation state and after the lifting is completed can avoid interference between the lifting arm 2 and the maglev vehicle body 6, so that the portal frame 1 can reach the lifting position of the maglev vehicle body 6 outside the maglev vehicle body 6 or be removed from the maglev vehicle body 6.
[0057] The fixed hole engages with the second pin hole 202 or the third pin hole 203, and the fixed pin 5 is installed to achieve the switching and positioning of the lifting arm 2.
[0058] The rotating pin 4 is not the only option; other rotating connecting parts that can enable the lifting boom 2 to rotate may also be used.
[0059] The fixed pin 5 is not the only option; other connecting parts that can fix the lifting arm 2 to the gantry frame 1 may also be used.
[0060] In this embodiment, the lifting equipment is connected to the lifting point via slings 9. The lifting equipment may be, but is not limited to, an overhead crane.
[0061] like Figure 5As shown, in use, the overhead crane is connected to the lifting point of the portal frame 1 via the sling 9, and the lifting arm 2 is rotated outside the portal frame 1 and fixed with the fixing pin 5. The lifting arm 2 hangs diagonally downwards, and then the clamp-type lifting beam is lifted to the lifting position, so that the portal frame 1 is positioned outside the maglev vehicle body, with the two columns 102 located on both sides of the maglev vehicle body. Then, the fixing pin 5 is removed, and the lifting arm 2 is rotated inside the portal frame 1, so that the support plate 3 on the lifting arm 2 supports the maglev vehicle body 6 at the designated position below, and then the lifting arm 2 is fixed with the fixing pin 5, adjusting the lifting arm 2 to the lifting position. In the above manner, the maglev vehicle body 6 is symmetrically supported at the front and rear by the two clamp-type lifting beams, and then the overhead crane can be started to smoothly and safely carry out the lifting and transportation of the maglev vehicle body 6.
[0062] The clamp-type lifting beam of this utility model is suitable for the body-in-white 6 of a maglev vehicle. By connecting the lifting equipment to the lifting points on the portal frame 1, the portal frame 1 is lifted to the lifting position, so that it is framed on the outside of the embedded medium-low speed maglev vehicle body-in-white 6. Then, by rotating the lifting arm 2, it supports the bottom of the maglev vehicle body-in-white 6. The maglev vehicle body-in-white 6 is lifted and transported by the lifting equipment. The operation is simple and convenient, which improves work efficiency and enhances the convenience and safety of lifting and transportation. It overcomes the problem of the lack of a lifting device suitable for the body-in-white of maglev vehicles in the prior art.
[0063] The clamp-type lifting beam of this utility model has a simple and reliable structure, low cost, simple operation, good economy, and good operability.
[0064] The clamp-type lifting beam of this utility model achieves the switching of the form and position of the lifting arm 2 by disassembling the fixing pin 5, and achieves the fixing of the lifting arm 2 by installing the fixing pin 5, thus taking into account both connection strength and convenience of actual use.
[0065] Example 2
[0066] The difference between this embodiment and Embodiment 1 is that:
[0067] like Figure 1 and Figure 4 As shown, two fixing plates 7 are installed at the connection between the crossbeam 101 and the column 102. The fixing plates 7 are fixedly connected to both sides of the column 102. A lifting pin 8 is connected between the two fixing plates 7, serving as the lifting point. The lifting straps 9 can be connected to the lifting pin 8. One end of each of the two lifting straps 9 is connected to the lifting pin 8 at both ends of the portal frame 1, and the other ends of the two lifting straps 9 are connected together for connection with the overhead crane. This facilitates stable lifting.
[0068] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
