Description

Technical Field

[0001] This utility model relates to the field of lifting beam technology, and more specifically, to a multi-functional lifting beam for a monorail crane. Background Technology

[0002] In the equipment installation process at fully mechanized coal mining faces, the transportation and installation of hydraulic supports is the most labor-intensive and time-consuming. Especially with the trend of heavy and large-scale fully mechanized mining supports, and due to the limitations of mine transportation conditions, large hydraulic supports need to be disassembled into several parts on the ground before being transported down the mine. After being reassembled at the underground working face, the entire support is moved to the installation position, and the entire support is adjusted to 90° using manual labor or a ground turning platform.

[0003] Monorail crane transportation, as an efficient auxiliary transportation method in coal mines, has one of its most important functions: transporting hydraulic supports, either as a whole or in parts, via a lifting beam. However, when the existing lifting beam makes a 90° turn, the center of gravity of the hydraulic support gradually deviates from the track line. Due to the characteristics of monorail suspension, the hydraulic support and lifting beam gradually tilt towards one side of the center of gravity, causing the track to tilt and overturn, posing a significant safety hazard.

[0004] Therefore, how to solve the problem of the center of gravity shift of the existing lifting beam when turning is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a multi-functional lifting beam for monorail crane locomotives, which can precisely adjust the center of gravity position of hydraulic supports, thereby ensuring the stability and smoothness of hydraulic supports during turning, reducing the time for manual adjustment and operation, and improving the installation efficiency of hydraulic supports.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-functional lifting beam for a monorail crane locomotive includes:

[0008] Composite beam;

[0009] The rotating beam is rotatably connected to the composite beam via a slewing mechanism.

[0010] At least one bidirectional drive device is provided on the rotating beam, and lifting devices are respectively connected to both ends of the bidirectional drive device for driving the lifting devices to move along the extension direction of the rotating beam;

[0011] The control device is signal-connected to the slewing mechanism, bidirectional drive device, and lifting device.

[0012] Preferably, there are two bidirectional drive devices, which are symmetrically arranged on the rotating beam.

[0013] Preferably, the bidirectional drive device is a bidirectional hydraulic cylinder.

[0014] Preferably, the lifting device includes a hoist and a lifting trolley, the lifting trolley is movable along the slide of the rotating beam, one end of the hoist is connected to the lifting trolley, and the other end is connected to the chain hook.

[0015] Preferably, the top surface of the composite beam is provided with a support device on both sides, and the support device is connected to the control device via signal.

[0016] Preferably, the jacking device is a jacking hydraulic cylinder, which includes a cylinder body and a piston rod. The cylinder body is located on the top surface of the composite beam, and the extended end of the piston rod is provided with a support plate. The support plate is used to contact the roadway roof and provide support force.

[0017] Preferably, the rotation angle of the rotary mechanism is greater than 90°.

[0018] Preferably, the slewing mechanism includes a slewing bearing and a slewing drive structure. The slewing bearing is used to rotatably connect the rotating beam and the composite beam, and the slewing drive structure is used to drive the rotating beam to rotate relative to the composite beam.

[0019] Preferably, the composite beam has connecting parts at both ends, which are used to connect with the hooks of the monorail crane. The composite beam is moved along the track by at least two load-bearing trolleys.

[0020] Preferably, the composite beam includes a main beam and a secondary beam, with the main beam connected to the monorail crane and the secondary beam rotatably connected to the rotating beam.

[0021] The multi-functional lifting beam of the monorail crane provided by this utility model includes a composite beam, a rotating beam, a bidirectional drive device, a lifting device, and a control device. Specifically, the control device is signal-connected to the slewing mechanism, the bidirectional drive device, and the lifting device. Operators can precisely control the movements of the slewing mechanism, the bidirectional drive device, and the lifting device through the control device, improving the accuracy and reliability of operation, reducing safety risks caused by operational errors, realizing automated control of the entire lifting and turning process, shortening the installation time of hydraulic supports, improving the overall efficiency of equipment installation in coal mine fully mechanized mining faces, and reducing the labor intensity of workers.

[0022] The rotating beam is rotatably connected to the combined beam via a slewing mechanism, enabling the hydraulic support to flexibly turn in the confined space of the well, especially achieving 90° turning adjustment. This meets the requirements for the hydraulic support to transition from its transport state to its installation state. At least one bidirectional drive device is located on the rotating beam, with lifting devices connected to both ends of the bidirectional drive device. This drive device is used to drive the lifting devices to move along the extension direction of the rotating beam. During the reassembly of the hydraulic support, the bidirectional drive device can adjust the position of the lifting point to achieve precise alignment of the hydraulic support components. During the 90° turning adjustment, by adjusting the position of the lifting point, the center of gravity of the hydraulic support can be adjusted to coincide as closely as possible with the structural center of the rotating beam. This avoids the lifting beam from swaying or tilting due to a shift in the center of gravity, significantly improving the stability and safety of the operation.

[0023] The multi-functional lifting beam of the monorail crane, designed in the above manner, can precisely adjust the center of gravity of the hydraulic support with the help of a two-way drive device, thereby ensuring the stability and smoothness of the hydraulic support during the turning process, reducing the time for manual adjustment and operation, and improving the installation efficiency of the hydraulic support.

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0046] It should be noted that the directional terms such as "front," "back," "left," and "right" used below are defined based on the accompanying drawings in the instruction manual.

[0047] The core of this utility model is to provide a multi-functional lifting beam for monorail crane locomotives, which can precisely adjust the center of gravity position of hydraulic supports, thereby ensuring the stability and smoothness of hydraulic supports during turning, reducing the time for manual adjustment and operation, and improving the installation efficiency of hydraulic supports.

[0048] Please refer to Figure 1 and Figure 2 A multi-functional lifting beam for a monorail crane includes a composite beam 1, a rotating beam 2, a slewing mechanism 3, a bidirectional drive device 4, a lifting device 5, and a control device 20.

[0049] Specifically, the control device 20 is signal-connected to the slewing mechanism 3, the bidirectional drive device 4, and the lifting device 5. Operators can precisely control the movements of the slewing mechanism 3, the bidirectional drive device 4, and the lifting device 5 through the control device 20, thereby improving the accuracy and reliability of the operation, reducing safety risks caused by operational errors, realizing automated control of the entire lifting and turning process, shortening the installation time of hydraulic supports, improving the overall efficiency of equipment installation in coal mine fully mechanized mining faces, and reducing the labor intensity of workers.

[0050] The rotating beam 2 is rotatably connected to the combined beam 1 via the slewing mechanism 3, enabling the hydraulic support to flexibly turn in the confined space of the well, especially to achieve 90° turning adjustment, meeting the requirements for the hydraulic support to switch from the transportation state to the installation state. At least one bidirectional drive device 4 is provided on the rotating beam 2, and the two ends of the bidirectional drive device 4 are respectively connected to the lifting device 5, which is used to drive the lifting device 5 to move along the extension direction of the rotating beam 2. During the reassembly of the hydraulic support, the bidirectional drive device 4 can adjust the position of the lifting point to achieve precise alignment of the hydraulic support components. During the 90° turning adjustment, by adjusting the position of the lifting point, the center of gravity of the hydraulic support can be adjusted to make it coincide with the structural center of the rotating beam 2 as much as possible, avoiding the tilting of the lifting beam caused by the offset of the center of gravity, which significantly improves the stability and safety of operation.

[0051] The multi-functional lifting beam of the monorail crane, designed in the above manner, can precisely adjust the center of gravity of the hydraulic support with the help of the bidirectional drive device 4, thereby ensuring the stability and smoothness of the hydraulic support during the turning process, reducing the time for manual adjustment and operation, and improving the installation efficiency of the hydraulic support.

[0052] In the above embodiment, there are two bidirectional drive devices 4, which are symmetrically arranged on the rotating beam 2.

[0053] It should be noted that the two bidirectional drive devices 4 are symmetrically arranged on the rotating beam 2, providing a more uniform driving force. This ensures that the lifting device 5 experiences more balanced force during movement, avoiding offset or swaying caused by unilateral drive and significantly improving the stability of the lifting process. During the reassembly and 90° steering adjustment of the hydraulic support, the symmetrically arranged bidirectional drive devices 4 can more precisely adjust the position of the lifting point, ensuring better alignment of the hydraulic support's center of gravity with the structural center of the rotating beam 2, further enhancing operational stability. The two bidirectional drive devices 4 can work independently or collaboratively, providing more flexible adjustment capabilities. During the reassembly of the hydraulic support, bidirectional adjustment can more precisely align the various components of the hydraulic support, ensuring the accuracy and reliability of the assembly.

[0054] The two bidirectional drive devices 4 are symmetrically arranged, which can distribute the load to the two devices, avoiding excessive force on a single device, thereby improving the load-bearing capacity of the entire lifting beam system. The symmetrically arranged bidirectional drive devices 4 can better disperse the point of force application, reduce local stress concentration on the rotating beam 2, and enhance the structural strength and service life of the entire lifting beam.

[0055] In the above case, the bidirectional drive device 4 is a bidirectional hydraulic cylinder.

[0056] Understandably, the double-acting hydraulic cylinder utilizes the powerful force provided by the hydraulic system to withstand large loads, ensuring stability and reliability when lifting heavy hydraulic support components. This allows the lifting beam to adapt to hydraulic support components of different weights and sizes, enhancing the system's versatility. In fully mechanized coal mining faces, hydraulic supports are typically large and heavy. The high load-bearing capacity of the double-acting hydraulic cylinder meets the lifting requirements of these heavy equipment, ensuring safety during transportation and installation. The hydraulic cylinder can be steplessly adjusted through the hydraulic system, precisely controlling the moving speed and position of the lifting device 5, ensuring accurate alignment of components and improving assembly efficiency and quality. Furthermore, the hydraulic cylinder's compact structure and small footprint allow for easy installation on the rotating beam 2 without adding extra volume or weight, enabling the lifting beam to operate flexibly within limited underground space and improving the equipment's adaptability.

[0057] Please refer to Figure 3 The lifting device 5 includes a lifting hoist 51 and a lifting trolley 52. ​​The lifting trolley 52 is moved along the slide of the rotating beam 2. One end of the lifting hoist 51 is connected to the lifting trolley 52, and the other end is connected to the chain hook 53.

[0058] It should be noted that the lifting trolley 52 is designed to move along the groove of the rotating beam 2, allowing the lifting point position to be flexibly adjusted according to the component positions and center of gravity of the hydraulic support. This ensures precise alignment and installation of each component, improving installation quality. During the installation of the hydraulic support, the adjustment of the lifting point is faster, reducing the time and labor intensity of manual adjustment, significantly improving installation efficiency and shortening installation time. This adjustability allows the lifting device 5 to adapt to objects of different sizes, shapes, and weights, as well as different lifting positions and angle requirements, greatly improving the applicability and versatility of the lifting device 5. Through the sliding adjustment of the lifting trolley 52 and the connection between the lifting hoist 51 and the chain hook 53, precise lifting and positioning of the object in space can be achieved. Especially in situations requiring high-precision lifting, such as the assembly of large equipment and the installation of important components, it effectively avoids collisions, damage, or installation errors caused by inaccurate lifting positions, improving the quality of lifting work. The design of this lifting device 5 can meet the needs of various lifting tasks. It can be used not only for lifting single objects but also for lifting multiple objects in combination, and can even handle complex lifting environments flexibly. The lifting hoist 51 is hinged to the lifting trolley 52 via the lifting rod, forming a stable lifting system. During the lifting process, the center of gravity and position of the lifted object can be effectively controlled, reducing safety risks caused by swaying or tilting of the lifted object. At the same time, the flexible connection method of the chain hook 53 also facilitates the adjustment and fixation of the lifted object during the lifting process, further improving the safety of the lifting operation.

[0059] Specifically, a double-acting hydraulic cylinder is installed on each side of the rotating beam 2. The piston rods at both ends of these double-acting cylinders are connected to a lifting trolley 52, forming a highly efficient lifting system. The entire system has four lifting trolleys 52, which run smoothly along the grooves of the rotating beam 2. Each lifting trolley 52 is suspended by a lifting hoist 51 and equipped with a chain hook 53. These four chain hooks 53 are used to lift various key components of the hydraulic support, including the support top beam, shield beam, support base, and the entire hydraulic support, ensuring the precision and efficiency of the lifting and installation process. The piston rods of the double-acting cylinders can extend from both ends of the cylinder barrel and have the ability to move in both directions, adapting to different specifications of hydraulic supports or the length of hydraulic support components. This feature allows the double-acting cylinders to precisely push the lifting trolleys 52 to move flexibly within the grooves of the rotating beam 2, thereby achieving precise adjustment of the lifting point positions of the lifting hoist 51 and the chain hook 53. This flexible adjustment function not only improves the adaptability and flexibility of the lifting process, but also ensures the stability and accuracy of each component of the hydraulic support during lifting and installation, greatly improving the efficiency and quality of the entire installation operation.

[0060] In the above embodiment, a support device 6 is provided on both sides of the top surface of the composite beam 1, and the support device 6 is connected to the control device 20 via a signal. When the hydraulic support is in the reassembly stage and when a critical 90° steering adjustment is performed, these support cylinders will extend precisely and tightly support the roadway roof, ensuring that the lifting beam remains stable throughout the entire operation, thereby greatly improving the safety and reliability of the operation.

[0061] Understandably, the jacking device 6, installed on both sides of the top surface of the composite beam 1, provides real-time top support during the lifting and turning of the hydraulic support. This effectively prevents the composite beam 1 from swaying or shifting due to uneven load or external forces during operation, ensuring the stability of the entire lifting process. The jacking device 6 is signal-connected to the control device 20 and can be dynamically adjusted according to actual needs during operation. In the complex underground environment, the jacking device 6 provides additional safety assurance, reducing safety risks caused by external impacts or operational errors, and protecting the safety of equipment and personnel.

[0062] Based on the above embodiments, the jacking device 6 is a jacking hydraulic cylinder, which includes a cylinder body and a piston rod. The cylinder body is located on the top surface of the composite beam 1, and the extended end of the piston rod is provided with a support plate. The support plate is used to contact the roadway roof and provide support force.

[0063] It should be noted that the hydraulic cylinder for supporting the roof utilizes the powerful force provided by the hydraulic system to generate a large supporting force, ensuring that the combined beam 1 can be stably supported on the roof of the roadway when lifting heavy hydraulic support components. This allows the lifting beam to adapt to hydraulic support components of different weights and sizes, enhancing the versatility of the system.

[0064] In the above embodiment, the rotation angle of the rotary mechanism 3 is greater than 90°.

[0065] Understandably, the rotation angle of the slewing mechanism 3 is greater than 90°, which can meet the turning requirements of the hydraulic support at different installation stages and positions. In a fully mechanized coal mining face, the installation position and direction of the hydraulic support may vary depending on the roadway layout and working face conditions. A rotation angle greater than 90° allows the lifting beam to flexibly adjust the direction of the hydraulic support, ensuring that it can be accurately installed in the predetermined position.

[0066] In a preferred embodiment, the slewing mechanism 3 includes a slewing bearing and a slewing drive structure. The slewing bearing is used to rotatably connect the rotating beam 2 and the composite beam 1, and the slewing drive structure is used to drive the rotating beam 2 to rotate relative to the composite beam 1.

[0067] It should be noted that the slewing bearing, as the core component of the slewing mechanism 3, provides a high-precision rotational connection, ensuring a stable connection and smooth rotation between the rotating beam 2 and the combined beam 1. This reduces friction and wear during rotation, improving the system's reliability and service life. The slewing bearing typically has a high load-bearing capacity, capable of withstanding large loads, ensuring stability when lifting heavy hydraulic support components. This allows the lifting beam to adapt to hydraulic support components of different weights and sizes, enhancing the system's versatility. The slewing drive structure provides reliable driving force, ensuring smooth rotation of the rotating beam 2 relative to the combined beam 1. This makes the rotation smoother, reducing jamming or stalling caused by insufficient drive, and improving operational efficiency and reliability. The slewing drive structure is typically connected to the control device 20, enabling precise rotation angle control. Operators can precisely control the rotation angle through the control device 20, ensuring accurate positioning of the hydraulic support during turning, improving installation accuracy and quality. The combined design of the slewing bearing and the slewing drive structure allows the rotating beam 2 to flexibly adjust its angle, meeting the turning requirements of the hydraulic support at different installation stages and positions. This flexibility is especially important in the complex environment of fully mechanized coal mining faces, ensuring that hydraulic supports can be accurately installed in their designated positions.

[0068] Please refer to Figure 4 The composite beam 1 has connecting parts at both ends, which are used to connect with the tie rod of the monorail crane 7. The composite beam 1 is moved along the track 9 by at least two load-bearing trolleys 8.

[0069] Understandably, the connecting parts at both ends of the composite beam 1 are connected to the tie rods of the monorail crane 7, ensuring a firm connection between the lifting beam and the monorail crane 7. This prevents loosening or detachment during lifting and transportation, improving operational safety and reliability. With at least two load-bearing trolleys 8 moving along the track 9, the composite beam 1 can move smoothly on the track 9. The arrangement of multiple load-bearing trolleys 8 distributes the load, reduces the stress on individual trolleys, lowers wear and tear and the risk of failure, ensuring the smooth operation of the composite beam 1 on the track 9. The movement of the composite beam 1 along the track 9 via the load-bearing trolleys 8 allows the lifting beam to flexibly adjust its position on the track 9, ensuring that the lifting beam can accurately transport the hydraulic support components to the designated location, improving installation efficiency and precision.

[0070] Track 9 is laid in the roadway, face roadway, and external mining area roadways. Both the first and second locomotives run on Track 9. Track 9 is fixed to the roadway roof and extends directly to the fully mechanized mining face, forming a complete Track 9 line. The monorail locomotive 7 runs along Track 9 and uses a lifting beam to transport and install hydraulic supports. To improve the efficiency of hydraulic support transportation and installation, the monorail locomotive 7 can be configured in two rows. One row of monorail locomotive 7 is equipped with a conventional universal lifting beam, responsible for transporting the hydraulic support components after they have been lowered into the mine to the roadway at the working face and placing them sequentially. The other row of monorail locomotive 7 is equipped with a multi-functional lifting beam, which lifts the components sequentially according to the hydraulic support assembly process, completing the reassembly of the hydraulic support. Subsequently, this locomotive lifts the assembled hydraulic support to the installation position and uses the rotation function of the multi-functional lifting beam to adjust the hydraulic support by 90°, finally completing the installation of the support.

[0071] Please refer to Figure 5 , Figure 6 and Figure 7 The first locomotive, equipped with three sets of standard lifting beams, is responsible for transporting the support top beam, shield beam, and support base to the assembly area in the roadway, and then lowering them to the ground in sequence. After lowering, the first locomotive returns along the same route, repeating the transportation operation. A ground auxiliary device 10 is installed on the ground in the assembly area. This device is mainly used for the reassembly of the hydraulic support; after the support base is lowered, it rests on the base plate 101 of the ground auxiliary device 10. The second locomotive is equipped with one set of multi-functional lifting beams. It first lifts the shield beam and assembles it with the support base, then lifts the support top beam to complete the assembly with the shield beam and support base. The ground auxiliary device 10 plays an important role in the reassembly of the hydraulic support, used to adjust the left and right position of the support base and the front and rear position of the shield beam, thereby improving installation efficiency and reducing manual labor intensity. The horizontal cylinder 103 in the ground auxiliary device 10 can adjust the left and right position of the support base, while the inclined support cylinder 102 is used to support and adjust the height of the shield beam. The inclined support cylinder 102 and the horizontal cylinder 103 can be single hydraulic supports, or hydraulic cylinders, pneumatic cylinders, or manual jacks can be used. The specific quantity is configured according to the actual working conditions, and the fulcrum position and specific structure are not specifically limited. The second locomotive uses a multi-functional lifting beam to lift the assembled hydraulic support and then transports it to the predetermined installation position in the cutting tunnel. At this time, the slewing drive structure drives the slewing support to rotate 90°, rotating the hydraulic support from the horizontal direction to the vertical direction and lowering it to the ground, completing the installation of the hydraulic support. There are two drive methods for the slewing support: one is worm gear motor drive, and the other is hydraulic cylinder connection push, and there are no specific requirements here. Before the hydraulic support is in place, a 90° vertical turn is required, so the rotation angle of the slewing support should be greater than, but not limited to, 90°.

[0072] In the above embodiment, the composite beam 1 includes a main beam 11 and a secondary beam 12. The main beam 11 is connected to the monorail crane 7, and the secondary beam 12 is rotatably connected to the rotating beam 2.

[0073] It should be noted that the main beam 11 is responsible for connecting with the monorail crane 7 and undertakes the main traction and support functions; the secondary beam 12 is rotatably connected to the rotating beam 2 and focuses on realizing the rotation function. This structural optimization makes the functional division of the composite beam 1 clearer and improves the overall performance of the system.

[0074] In summary, the core advantage of the multi-functional lifting beam for monorail cranes provided by this utility model lies in the application of a bidirectional hydraulic cylinder. This cylinder can precisely push the carrying trolley 8 to move back and forth along the slide of the rotating beam 2, thereby achieving flexible adjustment of the lifting points of the hydraulic hoist. Firstly, during the reassembly of the hydraulic support, after the hydraulic hoist lifts the top beam and shield beam of the hydraulic support to the appropriate position, the bidirectional hydraulic cylinder can precisely adjust the front and rear positions of the lifting points of the top beam and shield beam to ensure accurate alignment with the shaft holes of the base, greatly improving assembly efficiency and precision. Secondly, during the rotation of the hydraulic support, the bidirectional hydraulic cylinder adjusts the center of gravity of the hydraulic support to keep it as consistent as possible with the structural center of the lifting beam, effectively preventing the lifting beam from swaying or tilting, ensuring the stability and smoothness of the 90° turn adjustment, and significantly improving the safety and reliability of the entire installation process.

[0075] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0076] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0077] The above provides a detailed description of the multi-functional lifting beam for a monorail crane locomotive provided by this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of this utility model.
