Description

Technical Field

[0001] This utility model relates to the field of lifting device fixing technology, specifically to a connecting beam structure for a suction cup lifting device. Background Technology

[0002] Tunnel boring machine (TBM) segments are the main assembly components in TBM construction, and automated TBM segment production lines are crucial equipment for their production. Using automated TBM segment production lines for prefabrication allows for greater standardization, mechanization, and automation, making it easier to control the construction schedule, environmental impact, and quality. Automated TBM segment production lines are a type of automated production line used to manufacture TBM segments, and they are currently the main source of production in the market, with each process becoming increasingly automated.

[0003] With the development of automated tunnel segment production lines, the requirements for production line compatibility are becoming increasingly stringent. The automatic demolding process of these lines needs to be compatible with various automated tunnel segment lifting devices. These devices vary in structure and lifting points from different manufacturers, and even within the same manufacturer, different specifications of tunnel segments require different lifting devices. Traditionally, connecting beams and lifting devices are mostly connected using flanges, whose spacing cannot be changed, making it impossible to simultaneously adapt to lifting device connections with different lifting point distances. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides a connecting beam structure for a suction cup lifting device, the specific technical solution of which is as follows: A connecting beam structure for a suction cup lifting device is disclosed, used to connect an automatic vacuum suction cup lifting device to a demolding lifting sheave. The structure includes a connecting beam body, with sheave connecting plates located on both sides of the top of the connecting beam body corresponding to the positions of the demolding lifting sheave. A lifting device connecting plate is located at the bottom of the connecting beam body along its length. The demolding lifting sheave is bolted to the sheave connecting plate via a flange. The flange plate at the top of the automatic vacuum suction cup lifting device is detachably connected to the front and rear sides of the lifting device connecting plate via two opposing connecting pressure plates, thereby enabling the automatic vacuum suction cup lifting device to be adjusted in position within the designed length range of the connecting beam body.

[0005] Preferably, the length of the main body of the connecting beam is equal to the length of the connecting plate of the lifting device.

[0006] Preferably, the connecting pressure plate is L-shaped, including a horizontal part and a vertical part; the vertical part of the connecting pressure plate is provided with several connecting holes corresponding to the positions of the flange plate bolt holes; the front and rear sides of the lifting tool connecting plate are respectively inserted into the U-shaped groove formed by the two connecting pressure plates and the top of the flange plate, and the connecting pressure plate and the flange plate are fixed by fastening bolts.

[0007] Preferably, the main body of the connecting beam includes a main beam square tube and end plates on the left and right sides of the main beam square tube; each end plate can be detachably provided with a limit baffle on the side away from the main beam square tube.

[0008] Preferably, the size of the limiting baffle is larger than the size of the end plate.

[0009] Preferably, the demolding lifting rope wheel is connected to an automatic demolding lifting device.

[0010] More preferably, the automatic vacuum suction cup lifting device is fixed to the tube segment component by a vacuum suction cup at its bottom.

[0011] The beneficial effects of this utility model are: This utility model effectively solves the problem that existing segment demolding and hoisting require lifting tools of various specifications and manufacturers. By using connecting plates and connecting pressure plates, it achieves the fixation of the demolding lifting rope wheel to the main body of the connecting beam and the adjustable connection position of the automatic vacuum suction cup lifting tool on the main body of the connecting beam. This enables compatibility with multiple specifications of segments and different lifting point spacings, effectively improving production efficiency. Attached Figure Description

Detailed Implementation

[0014] The specific implementation of the connecting beam structure of the suction cup lifting device provided by this utility model will be further described with reference to the accompanying drawings and embodiments.

[0015] like Figures 1-3As shown, a connecting beam structure for a suction cup lifting device is used to connect an automatic vacuum suction cup lifting device 2 to a demolding lifting sheave 4. The structure includes a connecting beam body 7, with sheave connecting plates 8 positioned on both sides of the top of the connecting beam body 7 corresponding to the positions of the demolding lifting sheave 4. A lifting device connecting plate 9 is provided at the bottom of the connecting beam body 7 along its length. The demolding lifting sheave 4 is bolted to the sheave connecting plate 8 via a flange. The flange plate 10 at the top of the automatic vacuum suction cup lifting device 2 is detachably connected to the front and rear sides of the lifting device connecting plate 9 via two opposing connecting pressure plates 5, thereby allowing the automatic vacuum suction cup lifting device 2 to be adjusted in position within the designed length range of the bottom of the connecting beam body 7.

[0016] like Figure 5 As shown, the connecting pressure plate 5 is L-shaped and includes a horizontal part and a vertical part; the vertical part of the connecting pressure plate 5 is provided with several connecting holes at the positions corresponding to the bolt holes of the flange plate 10 (not shown in the figure); the connecting holes of the connecting pressure plate 5 are connected to the bolt holes of the flange plate 10 through fastening bolts 6.

[0017] During installation, first determine the lifting point position of the automatic vacuum suction cup lifter 2 on the connecting beam body 7. Then, place the automatic vacuum suction cup lifter 2 and the two connecting pressure plates 5 at the lifting point position. At this time, the front and rear sides of the lifter connecting plate 9 are respectively inserted into the U-shaped groove formed by the two connecting pressure plates 5 and the top of the flange plate 10. Then, fasten the two connecting pressure plates 5 and the front and rear sides of the flange plate 10 with the fastening bolts 6. The automatic vacuum suction cup lifter 2 is then firmly fixed to the connecting beam body 7 by the clamping force of the connecting pressure plates 5. When it is necessary to readjust the lifting point position of the automatic vacuum suction cup lifter 2 on the connecting beam body 7, simply loosen the fastening bolts 6, allowing the U-shaped groove formed by the top of the connecting pressure plates 5 and the flange plate 10 to slide along the front and rear sides of the lifter connecting plate 9 until the desired lifting point position is reached, then tighten the fastening bolts 6 again.

[0018] It is worth noting that the length of the connecting beam body 7 is equal to or slightly greater than the length of the lifting device connecting plate 9. Additionally, the friction coefficient can be increased by roughening the pressing surface of the connecting pressure plate 5, further improving the clamping effect.

[0019] like Figure 4 As shown, the connecting beam body 7 includes a main beam square tube and end plates 701 on both sides of the main beam square tube; each end plate 701 is detachably equipped with a limit baffle 3 on the side away from the main beam square tube to prevent the automatic vacuum suction cup lifting device 2 from detaching from the connecting beam body 7 during movement. Preferably, the size of the limit baffle 3 needs to be larger than the size of the end plate 701.

[0020] More preferably, the demolding lifting rope wheel 4 is connected to the automatic demolding lifting device, and the automatic vacuum suction cup lifting device 2 is fixed to the segment component 1 through the vacuum suction cup at its bottom, thereby realizing the lifting of the segment component 1 during the demolding process.

[0021] Compared to traditional connecting beam structures, which mostly use fixed flange connections with automatic vacuum suction cup lifters, different sizes of tunnel segments require different automatic vacuum suction cup lifters with varying lifting point distances. However, because the spacing on the connecting beam cannot be freely adjusted, traditional connecting beam structures cannot achieve compatibility with multi-sized tunnel segments and automatic vacuum suction cup lifters with different lifting point distances. This invention effectively solves the problem of requiring various specifications and manufacturers of lifters for tunnel segment demolding and lifting. By using different connecting plates and pressure plates, it achieves the fixation of the demolding lifting rope pulley to the main body of the connecting beam and allows for adjustable connection positions of the automatic vacuum suction cup lifter on the main body of the connecting beam, effectively improving production efficiency.
