Description

Technical Field

[0001] This utility model relates to a lifting beam for transporting mining materials, specifically, a heavy-duty lifting beam for a monorail crane. Background Technology

[0002] Monorail cranes are currently the mainstream auxiliary transportation equipment in underground mines. Compared with traditional auxiliary transportation equipment, they have advantages such as large load-bearing capacity, high flexibility of application, small footprint, energy saving and environmental protection, which have made them popular among industry practitioners.

[0003] A monorail crane is a platform for transporting materials and personnel, requiring a large number of supporting equipment and devices to ensure the safe and efficient transport of materials and personnel of different types, volumes, and weights. The lifting beam is a key supporting device for the monorail crane; it connects to lifting tools to transport materials and to personnel carriers to transport workers. Underground mining operations involve a large amount of heavy-duty, large-volume equipment or goods. Furthermore, due to the complexity of roadways, heavy-duty lifting beams that combine high load capacity with good roadway maneuverability have become an important requirement for auxiliary transportation operations in mines.

[0004] Traditional lifting beams are relatively short in length to ensure the passage of tunnels. This shorter length limits the number of trolleys that can be used, directly impacting their load-bearing capacity. Longer lifting beams, on the other hand, are prone to jamming when navigating curves or being transported materials, making them unsuitable for transporting the diverse materials required in the mining industry. Summary of the Invention

[0005] To address the aforementioned problems, this utility model provides a heavy-duty lifting beam for monorail cranes, which has the capacity to transport large equipment in tunnels, can be adapted to different transport frames, and can meet the transportation needs of different materials.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A heavy-duty lifting beam for a monorail crane is disclosed. The monorail crane is equipped with a carrying trolley and a lifting beam. The carrying trolley runs on a track, and a connecting beam is connected to the lower end of the carrying trolley. A set of carrying trolleys is respectively set at the front and rear ends of each set of connecting beams.

[0008] The lifting beam includes a first main beam, a second main beam, a first auxiliary beam, and a second main beam. The front and rear ends of the first and second main beams are respectively connected to a connecting beam via a first pin.

[0009] The first main beam is connected to the first secondary beam at the middle position via the second pin. The second main beam has a second secondary beam at the middle position. The second main beam and the second secondary beam are perpendicular. Connecting chains are attached to the two ends of the first secondary beam and the two ends of the second secondary beam. The chains connected to the same side end of the first and second secondary beams are connected to a set of lifting frames. The lower parts of the two ends of the first and second secondary beams correspond to a set of lifting frames. Chain hooks are provided at the lower parts of the two ends of the lifting frames. The chain hooks are used to fix the goods to be transported.

The longitudinal direction of the H-shaped frame is consistent with the direction of the connecting beam. The two ends of the transverse frames are threaded to the notched ends of the H-shaped frame. The first pin is provided in the middle of the transverse frame and connected to the connecting beam.

[0011] According to the aforementioned heavy-duty lifting beam for a monorail crane, the second auxiliary beam is fixed on the second main beam.

[0012] According to the aforementioned heavy-duty lifting beam for a monorail crane, the lifting frame is a box structure with an internal winch lifting mechanism.

[0013] According to the aforementioned heavy-duty lifting beam for a monorail crane, two sets of lifting frames are arranged on both sides of the first main beam and the second main beam, and are symmetrically arranged with respect to the center lines of the first main beam and the second main beam in the length direction.

[0014] According to the aforementioned heavy-duty lifting beam for a monorail crane, the first main beam and the second main beam are respectively connected to eight sets of load-bearing trolleys via connecting beams, and the load-bearing trolleys at the ends are hinged to other adjacent load-bearing trolleys via connecting rods, with the hinge rotation direction being the plane direction where the first main beam and the second main beam are located.

[0015] According to the aforementioned heavy-duty lifting beam for a monorail crane, the load-bearing trolley and the connecting beam are connected by a ball joint.

[0016] According to the aforementioned heavy-duty lifting beam for a monorail crane, a first main beam and a second main beam are provided with multiple lifting lugs, which are connected to an auxiliary chain, and the auxiliary chain is connected to the goods to be transported.

Detailed Implementation

[0027] The specific structure of this utility model will be further described below:

[0028] This utility model is described in the appendix. Figure 1 This utility model relates to a heavy-duty lifting beam for a monorail crane locomotive, which may be 2, 3, or 4. The monorail crane locomotive is equipped with a carrying trolley and a lifting beam. The carrying trolley runs on the track, and a connecting beam is connected to the lower end of the carrying trolley.

[0029] The lifting beam includes a first main beam, a second main beam, a first auxiliary beam, and a second main beam. The front and rear ends of the first and second main beams are connected to the middle of the connecting beams via first pins. Each set of connecting beams has a load-bearing trolley at its front and rear ends. The load-bearing trolleys are connected to the connecting beams via ball joints, facilitating the independent turning of the front and rear load-bearing trolleys when the track turns. The first main beam of this device is hinged to the two sets of connecting beams via first pins, allowing them to rotate relative to each other in the horizontal direction, facilitating turning along the track at curves.

[0030] The first and second main beams are connected to four sets of load-bearing trolleys via connecting beams. The load-bearing trolleys at their ends are hinged to adjacent load-bearing trolleys via connecting rods, with the hinged rotation direction aligned with the plane of the first and second main beams. This structure also adapts to track turning. The connecting rods transmit tension, enabling synchronous movement of the first and second main beams.

[0031] Each lifting beam is equipped with eight load-bearing trolleys, which can evenly distribute the weight of the goods on the monorail track and distribute it to as many monorail track connecting anchors as possible, thereby improving the load-bearing stability during transportation and avoiding overload pressure on the entire track system caused by heavy loads.

[0032] Furthermore, the first main beam is connected to the first secondary beam at its middle position via a second pin, allowing the first secondary beam and the first main beam to rotate relative to each other in the horizontal direction. The second main beam has a fixedly connected second secondary beam at its middle position, perpendicular to the second secondary beam, and in this structure, the second main beam and the second secondary beam are fixed and do not rotate relative to each other. When this device is running on a monorail, the first main beam is in front and the second main beam is behind. The rotating structure of the first main beam and the first secondary beam facilitates steering along the track during operation, similar to the front steering mechanism of a car.

[0033] Connecting chains are suspended from both ends of the first secondary beam. Third pins, arranged vertically, are installed at both ends of the second secondary beam, connecting to chain connectors. These chain connectors are connected to the suspended connecting chains. Connecting chains at the same end of both the first and second secondary beams connect to a set of lifting frames. Each end of the first and second secondary beams corresponds to a set of lifting frames. The two sets of lifting frames are arranged symmetrically along the length centerline of the first and second main beams, on both sides of the first and second main beams. Chain hooks are installed at the lower ends of the lifting frames to secure the goods to be transported.

[0034] Because the first and second main beams will rotate relative to each other at the track turning point, the lifting frame and the first auxiliary beam will undergo displacement deformation due to the actual turning of the connecting chain. That is, when the first auxiliary beam is at the track turning point, the lifting frame and the cargo will maintain a certain distance in their original direction due to inertia, and the connecting chain will become skewed. At the same time, the second auxiliary beam will turn with the carrying trolley. Here, the lifting frame needs to rotate horizontally relative to the second main beam and the second auxiliary beam to eliminate the angle change between the lifting frame and the cargo turning in an integrated state and the second main beam, reduce the skew of the connecting chain connected to the second main beam, and avoid overloading of the connecting chain and tail swing of long-sized cargo.

[0035] Furthermore, the first main beam includes an H-shaped frame and transverse frames at both ends. The longitudinal direction of the H-shaped frame is consistent with the direction of the connecting beam. The two ends of the transverse frames are threaded to the notched ends of the H-shaped frame. The first pin is set in the middle of the transverse frame and connected to the connecting beam. With the H-shaped frame and transverse frame structure, the carrying trolley is located in the middle of the opening of the H-shaped frame, which can leave space for the carrying trolley, avoid the problem of large lower dimensions caused by connecting the lower part of the carrying trolley, and also raise the fixed position of the goods as much as possible to avoid the problem of large-sized goods being supported by the bottom.

[0036] The lifting frame in this device is a box structure with an internal winch lifting mechanism. The winch mechanism can first raise the goods to a high position and then use chain hooks to fix them for easy loading.

[0037] Furthermore, the first and second main beams are equipped with multiple lifting lugs, which are connected to auxiliary chains. These auxiliary chains are connected to the goods to be transported. The auxiliary chains can secure the moving parts of the goods, connecting the main body and moving parts of the goods as a whole, thus preventing the moving parts from shifting during the transport of the entire equipment.

[0038] This utility model designs a heavy-duty lifting beam for monorail cranes that combines long-length carrying capacity with tunnel passability. It can be adapted to different transport frames to meet the transportation needs of different materials and improve the applicability of the lifting beam.
