Description

Technical Field

[0001] The present application relates to the field of monorail crane transportation, and in particular to a monorail crane transportation vehicle hanging device. Background Art

[0002] Monorail crane transportation is widely used in my country's coal industry due to its advantages such as high transportation efficiency, flexible material lifting methods, and quick track installation.

[0003] It uses a special I-beam suspended above the mine tunnel as a track, and is connected to a train set by hanging vehicles with various functions, and is towed by traction equipment to run along the track. Since the monorail crane has a small cross-section, it has a high utilization rate of the tunnel cross-sectional space and can also be used for continuous non-transshipment transportation in horizontal and inclined tunnels, with low investment and maintenance costs.

[0004] However, when the monorail crane is used to transport mine cars, the mine cars are easily squeezed and deformed due to the small number of hanging points, and the mine cars are not hung properly. In addition, due to the influence of the track, the mine cars will also swing, posing a safety hazard. Summary of the invention

[0011] In a feasible implementation, at least two vehicle connection devices are fixedly mounted on the bottom of the hanging bracket;

[0012] The hanging frame comprises at least four cross beams, and the number of the cross beams is half of the number of the fixing chains.

[0023] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0024] At present, when monorail cranes are used to transport mine cars, due to the small number of hanging points, the mine cars are easily squeezed and deformed, and the mine cars are not hung properly. In addition, due to the influence of the track, the mine cars will also swing, posing a safety hazard.

[0025] In view of the above problems, the embodiment of the present application provides an efficient and stable monorail crane transport vehicle hanging device, which aims to improve the transportation safety and efficiency of heavy equipment such as mining cars, material cars and tool cars on the monorail crane system. The core component of the device is a hanging frame 10, with lifting hook connectors 20 precisely welded on both sides of the top, made of high-strength materials, to ensure stable docking with the lifting hook of the monorail crane, and achieve fast and safe connection and separation.

[0026] At least one set of vehicle connection devices 30 is arranged at the bottom of the hanging frame 10 to meet the transportation requirements of different sizes and weights. Each set of vehicle connection devices 30 consists of four sturdy fixed chains 31 and two auxiliary chains 32. The fixed chains 31 serve as the load-bearing body, and their upper ends are directly welded or bolted to the bottom of the hanging frame 10 to ensure the directness and reliability of force transmission. The four fixed chains 31 are deployed in a symmetrical layout to form a stable support frame. In actual operation, the two fixed chains 31 on the same side flexibly bypass the bottom of the vehicle to be transported, and are connected to the two fixed chains 31 on the other side through quick connection devices such as shackles to form a closed-loop structure. Not only does it simplify the connection process, but it also effectively disperses the weight of the vehicle through multiple points of force, avoiding vehicle deformation or skewness caused by excessive force at a single point, and significantly improving the stability and safety during transportation.

[0027] The two auxiliary chains 32 are arranged perpendicular to the fixed chains 31 and are respectively fixedly connected between adjacent fixed chains 31 to form lateral constraints on the vehicle. In complex transportation environments such as inclined lanes, the auxiliary chains 32 can effectively prevent the vehicle from accidentally slipping off between the fixed chains 31 due to the force of gravity, further enhancing the safety and reliability of the entire suspension system.

[0028] In addition, considering the shaking factors that may be caused by the monorail hanging track, the hanging frame 10 constructs a connection system with good buffering and shock absorption effects through the combination of the fixed chain 31 and the auxiliary chain 32. Even if the hanging frame 10 shakes due to uneven tracks or improper operation, the force generated will be effectively absorbed and dispersed by these chain structures, greatly reducing the direct impact on the lifting vehicle, thereby significantly alleviating the shaking problem during the vehicle lifting process and ensuring stable and smooth transportation.

[0029] Figure 1 is a structural schematic diagram of a monorail crane transport vehicle hanging device provided in one embodiment of the present application, Figure 2 yes Figure 1 Refer to the top view of Figure 1 and Figure 2 As shown, the embodiment of the present application provides a monorail crane transport vehicle hanging device, including a hanging frame 10, the top two sides of the hanging frame 10 are respectively fixedly installed with a lifting hook connection member 20, and the bottom of the hanging frame 10 is fixedly installed with at least one vehicle connection device 30;

[0030] The vehicle connection device 30 includes four fixed chains 31 and two auxiliary chains 32. The upper ends of the fixed chains 31 are fixedly connected to the bottom of the hanging frame 10. The auxiliary chains 32 are perpendicular to the fixed chains 31, and the two ends of each auxiliary chain 32 are fixedly connected to the corresponding fixed chain 31.

[0031] In actual application, the lifting hook connector 20 is connected to the lifting hook of the monorail crane, and a vehicle connecting device 30 is connected to a mine car, or a material car and a tool car, etc., and is connected to the other two fixed chains 31 after passing around the bottom of the vehicle through two fixed chains 31 located on the same side. The connection between the fixed chains 31 can be achieved by a shackle. After the vehicle is lifted, there are multiple fulcrums between the fixed chain 31 and the lifting vehicle, which can prevent the vehicle from deforming and tilting, thereby improving the stability of the monorail crane when transporting the vehicle. The two auxiliary chains 32 are respectively located on both sides of the vehicle, which can prevent the lifting vehicle from slipping between the four fixed chains 31 during transportation in the inclined lane. The hanging frame 10 is connected to the vehicle through the fixed chain 31 and the auxiliary chain 32. Even if the hanging frame 10 is affected by the monorail crane track and causes it to shake, the force generated is difficult to be transmitted to the lifting vehicle through the fixed chain 31, thereby alleviating the shaking problem of the vehicle during lifting.

[0032] In some examples, the lifting object connected to the vehicle connection device 30 may also be a container. Since a lifting ring is provided on the container, the bottom end of the fixing chain 31 may be connected to the lifting ring through a shackle.

[0033] In the above embodiment, the flexibility and versatility of the vehicle connection device 30 are further demonstrated. It can not only stably connect traditional transportation tools such as mine cars, material cars and tool cars, but also adapt to more extensive and special cargo lifting needs, such as monorail lifting transportation of containers. When lifting the container, the operator can easily connect the bottom end of the fixed chain 31 to the lifting ring on the container through the shackle. As a widely used connecting piece, the shackle has a sturdy structure and is easy to operate. It can quickly and reliably connect and separate the chain and the lifting ring. By accurately adjusting the position and tightening degree of the shackle, it can ensure that the connection between the fixed chain 31 and the container lifting ring is both stable and safe, effectively preventing accidental falling off or breaking during the lifting process.

[0034] In some examples, the hanging bracket 10 includes a main beam 11 and at least two cross beams 12, the main beam 11 and the cross beams 12 are perpendicular to each other, the main beam 11 is fixedly connected to the cross beams 12, the lifting hook connectors 20 are fixedly installed on the top of the main beam 11, and the upper ends of the fixed chains 31 are respectively fixedly connected to the corresponding ends of the cross beams 12.

[0035] The cross beam 12 spans over the main beam 11 and is tightly coupled to the main beam 11 through a precise fixed connection. This vertically staggered layout not only enhances the overall rigidity of the hanger 10, but also effectively disperses stress, making the structure more stable and reliable.

[0036] The fixing chain 31 can be connected to the crossbeam 12 via a shackle. It is easy to understand that a hole needs to be opened on the crossbeam 12 to allow the upper end or shackle of the fixing chain 31 to pass through. This connection method not only ensures the stability of the fixing chain 31 during the hoisting process, but also facilitates subsequent maintenance and replacement.

[0037] Reference Figure 2 As shown, the hanging bracket 10 is a symmetrical structure, which helps to improve the balance and stability of the entire device. In practical applications, the symmetrical structure can reduce the additional stress caused by imbalance, thereby extending the service life of the hanging bracket 10.

[0038] In some examples, the main beam 11 and the cross beam 12 are welded.

[0039] In other examples, the main beam 11 and the cross beam 12 may be connected by bolts, or welded on the basis of the bolt connection, so as to ensure the connection strength between the main beam 11 and the cross beam 12.

[0040] In the above embodiment, the four fixed chains 31 in a vehicle connection device 30 can be distributed at the four corners, so that when connected to the vehicle, the vehicle can be lifted more evenly, which is beneficial to improving the lifting stability of the vehicle and the connection stability with the vehicle.

[0041] In some examples, the main beam 11 and the cross beam 12 are 11# mining I-beams.

[0042] In the above embodiment, the 11# mining I-beam has high strength, which can ensure that the hanging frame 10 has a good load-bearing capacity to avoid deformation or even breakage after long-term use.

[0043] In some examples, at least two vehicle connection devices 30 are fixedly mounted on the bottom of the hanging bracket 10;

[0044] The hanging frame 10 includes at least four cross beams 12 , and the number of the cross beams 12 is half of the number of the fixing chains 31 .

[0045] In the above embodiment, each vehicle connecting device 30 corresponds to two cross beams 12, and each cross beam 12 corresponds to two fixed chains 31. After the hanging frame 10 is connected to the monorail crane, it can be connected to at least two mine cars through at least two vehicle connecting devices 30, thereby realizing the simultaneous transportation of multiple mine cars, and only occupying two lifting hooks of the monorail crane, the transportation efficiency is higher, the time and labor cost required for a single transportation are reduced, and more efficient transportation operations can be achieved without adding additional equipment burden, meeting the urgent needs for efficient and safe transportation in complex environments such as modern mines.

[0046] In some examples, a lifting hole 21 is formed on the lifting hook connector 20 .

[0047] In some examples, the lifting hook connector 20 is made of an I-beam, and the lifting hole 21 is arranged in the middle of the vertical beam of the I-beam.

[0048] It is easy to understand that the connection method between the lifting hook connector 20 and the main beam 11 can refer to the connection method between the main beam 11 and the cross beam 12, which will not be repeated here.

[0049] It should be noted that when connecting the device to the monorail crane, the lifting hook of the monorail crane is first lowered to the lifting hole 21, and the lifting hook is fixed with a pin after passing through the lifting hole 21 to prevent it from being unhooked.

[0050] In some specific embodiments, the length of the lifting hook connecting member 20 is 0.4-0.6 m.

[0051] In the above embodiment, the lifting hook connector 20 is connected to the main beam 11, which can ensure that there is sufficient connection strength between the two. Compared with directly installing the lifting ring on the top of the main beam 11, it has a larger contact area to prevent the two from loosening after bearing. The lifting hole is set in the middle of the vertical beam of the I-beam, which can slightly reduce the height of the hanging point, thereby facilitating the lifting height. The middle of the vertical beam is also the center of the entire I-beam, which can more evenly apply force to the lifting hook connector 20, further reducing the possibility of the hanging frame 10 being skewed.

[0052] In some examples, the fixed chain 31 is an M16 lifting chain.

[0053] It is easy to understand that the lengths of the fixed chain 31 and the auxiliary chain 32 depend on the model of the mining vehicle and the conditions of the use site, and this application does not limit this.

[0054] The present application provides a monorail crane transport vehicle hanging device, which serves as a connection between the monorail crane and the hoisted object. It is connected to the lifting hook of the monorail crane through a lifting hook connector 20, and the mine car is fixed through the connection between the fixed chains 31, so that the two lifting hooks can lift at least two mine cars, and the transportation efficiency is higher. There are multiple fulcrums between the fixed chain 31 and the mine car, and the auxiliary chain 32 can be used to avoid deformation and skewness of the mine car. The lifting hook is no longer directly connected to the hoisted object. Even if the lifting hook slides, it is difficult to transmit it to the hoisted object through the fixed chain 31, etc., thereby alleviating the shaking of the hoisted object and ensuring transportation safety. The connection method is relatively simple and can be completed by one person.

[0055] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on the several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.

[0056] The above specific implementation methods further explain in detail the purpose, technical solutions and beneficial effects of the embodiments of the present application. It should be understood that the above are only specific implementation methods of the embodiments of the present application and are not used to limit the protection scope of the embodiments of the present application. Any modifications, equivalent substitutions, improvements, etc. made on the basis of the technical solutions of the embodiments of the present application should be included in the protection scope of the embodiments of the present application.
