[0038] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0039] In the description of the embodiments of the present utility model, it should be noted that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present utility model. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.
[0040] Combine the following Figures 1 to 5 The crane connection device of the utility model is described, which is used to connect a first crane 100 and a second crane 200. The first crane 100 is provided with a first boom 101, and the second crane 200 is provided with a second boom 201.
[0041] like Figure 1 and Figure 2As shown, the utility model provides a crane connection device, including a first connection member 1 and a second connection member 2, wherein the first connection member 1 is connected to the head of a first arm 101; the angle between the top side of the first connection member 1 and the center line a of the first arm 101 is greater than 60°, and the second connection member 2 is connected to the head of a second arm 201; the angle between the top side of the second connection member 2 and the center line b of the second arm 201 is greater than 60°. The first connection member 1 and the second connection member 2 have structures matching the corresponding arm heads to ensure stable and safe connection, without changing the pulley blocks of the first crane 100 and the second crane 200, and are easy to install.
[0042] The second connecting member 2 is docked with the first connecting member 1 to ensure that the two can be tightly and accurately connected together, so that when the first crane 100 and the second crane 200 lift the same workpiece, the first crane 100 and the second crane 200 can form a more stable gantry structure, thereby improving the load capacity of the first crane 100 and the second crane 200 for lifting the workpiece 300.
[0043] The first connecting member 1 and the second connecting member 2 are connected, and the first arm 101, the second arm 201 and the ground on which the crane is placed form a stable triangular structure, which plays a role in assisting the lifting of the load. The second connecting member 2 is connected to the first connecting member 1, and the first crane 100 and the second crane 200 are formed into an integrated structure to improve the stability of the lifting action. By the first crane 100 and the second crane 200 hoisting a workpiece at the same time, the crane connection device can significantly improve the efficiency of hoisting large or heavy workpieces. Because the two cranes can work together, the adjustment and coordination time during the hoisting process is reduced. In a feasible embodiment of the utility model, the first connecting member 1 and the second connecting member 2 have the same structure, which improves the versatility of the components. The same structure means that the first connecting member 1 and the second connecting member 2 can use the same process and materials in the design and manufacturing process, thereby reducing production costs and complexity. In addition, the same structure is also convenient for inventory management and maintenance, because only one type of connecting member needs to be managed, which reduces the types and quantities of inventory and simplifies the maintenance process.
[0044] In addition, the improvement in versatility makes the first connecting member 1 and the second connecting member 2 excellent in interchangeability. During the collaborative operation of the crane, if one of the connecting members is damaged or needs to be replaced, the other connecting member can be directly replaced without additional adaptation or adjustment. This interchangeability not only improves work efficiency, but also reduces downtime and costs caused by replacing parts.
[0045] See again Figure 2As shown, in a feasible embodiment of the present invention, a tension sensor 3 is provided at least at one place between the first connecting member 1 and the head of the first arm 101, and between the second connecting member 2 and the head of the second arm 201. The tension sensor 3 is used to detect the tension of the first connecting member 1 or the second connecting member 2 to ensure the normal use of the first connecting member 1 and the second connecting member 2. The tension sensor 3 can be a pull plate type sensor, a pin shaft type sensor, or a sensor of other structural forms, as long as the tension detection can be realized.
[0046] Specifically, a pin-type tension sensor is arranged between the first connecting member 1 and the top of the first arm 101, and a pin-type tension sensor is arranged between the second connecting member 2 and the top of the second arm 201, wherein the pin-type tension sensor is usually an integral hollow cross-section circular shaft with a compact structure, can be assembled with various load-bearing components, and can measure tiny pressure changes.
[0047] A pull plate type tension sensor is provided between the first connecting member 1 and the side of the first arm 101, and a pull plate type tension sensor is provided between the second connecting member 2 and the side of the second arm 201. The pull plate tension sensor has high precision and a wide measurement range, and has a long service life and a simple structure. At the same time, its rugged and durable characteristics also ensure the stability and reliability of the sensor in various harsh environments.
[0048] like Figure 3 , Figure 4 and Figure 5 As shown, in a feasible embodiment of the utility model, the first connecting member 1 is connected to the first crane 100 at the first connecting point, and the second connecting member 2 is connected to the second crane 200 at the second connecting point, and the first connecting point and the second connecting point each have four groups, the first connecting member 1 and the first crane 100 have four groups of connecting points, and the second connecting member 2 and the second crane 200 have four groups of connecting points, so that the first connecting member 1 and the first crane 100 are firmly connected, and the second connecting member 2 and the second crane 200 are firmly connected. The four groups of connecting points significantly enhance the stability and safety of the connection. During the hoisting process, the force applied by the workpiece 300 to the first connecting member 1 and the second connecting member 2 is transmitted to the corresponding arm through the four groups of connecting points corresponding to each connecting member, thereby reducing the pressure on a single connecting point. This not only helps to reduce the risk of damage caused by overloading of the connection point, but also ensures the stability and safety of the crane when hoisting large or heavy workpieces.
[0049] In a feasible embodiment of the present invention, the first connecting member 1 and the second connecting member 2 are connected to a third connecting point, and the third connecting point has two groups to make the connection between the first connecting member 1 and the second connecting member 2 more secure, providing a solution that balances stability and complexity.
[0050] like Figure 3 As shown, in a feasible embodiment of the utility model, the first connecting member 1 includes two pairs of first vertical rods 11 and four first cross rods 12, the first end of each first vertical rod 11 is connected to the boom head of the first crane 100; the second ends of the two first vertical rods 11 in the same pair are close to each other and connected into one by a plate; the two ends of each first cross rod 12 are respectively connected to the corresponding first vertical rod 11 to form a closed loop structure.
[0051] The second connecting member 2 includes two pairs of second vertical rods 21 and four second cross rods 22. The first end of each second vertical rod 21 is connected to the boom head of the second crane 200; the second ends of the two second vertical rods 21 in the same pair are close to each other; the two ends of each second cross rod 22 are respectively connected to the corresponding second vertical rod 21 to form a closed loop structure.
[0052] The second end of the first vertical rod 11 and the second end of the second vertical rod 21 are butted against each other to achieve butt connection between the first connecting member 1 and the second connecting member 2 .
[0053] By providing the first vertical rod 11, the first cross rod 12, the second vertical rod 21 and the second cross rod 22, the first connecting member 1 and the second connecting member 2 have a stable and strong frame, which can effectively connect the boom head of the crane with the connecting device. This structure not only takes into account the stability and supporting capacity of the connecting device, but also simplifies the connection process and improves the connection accuracy and efficiency. It is suitable for large-scale projects or projects that require multiple cranes to work together, and provides a more reliable and efficient solution for hoisting operations.
[0054] In a feasible embodiment of the present invention, a connecting plate is disposed at the second end of the first vertical rod 11 , and a clamping plate is disposed at the second end of the second vertical rod 21 , and the clamping plate is correspondingly and adaptively connected to the connecting plate.
[0055] It should be understood that as long as the clamping plate and the connecting plate can be connected, the luffing planes of the first crane 100 and the second crane 200 can be overlapped to achieve the fixation of the luffing planes. At this time, the structure of the first connecting member 1 is different from that of the second connecting member 2, which improves the convenience of installation.
[0056] See again Figure 3As shown, in a feasible embodiment of the present invention, the second ends of the two pairs of first vertical rods 11 are respectively provided with a first connecting plate 13 and a first clamping plate 14, and the second ends of the two pairs of second vertical rods 21 are respectively provided with a second clamping plate 24 and a second connecting plate 23, the first clamping plate 14 and the second connecting plate 23 are correspondingly matched and matched, and the second clamping plate 24 and the first connecting plate 13 are correspondingly matched and matched. The structures of the first connecting plate 13 and the second connecting plate 23 can be the same, and the structures of the first clamping plate 14 and the second clamping plate 24 can be the same.
[0057] It should be understood that the first connecting member 1 and the second connecting member 2 have the same structure and only need to be rotated 180 degrees during installation, thereby improving the versatility of the components.
[0058] like Figure 5 As shown, in a feasible embodiment of the present invention, a reinforcing rod 15 is arranged between adjacent first vertical rods 11, and the reinforcing rod 15 forms a triangular structure with the first vertical rod 11 and the first horizontal rod 12 to enhance the stability of the structure of the first connecting member 1 and the second connecting member 2.

[0062] In the description of the embodiments of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium.
