Description

Technical Field

[0001] This utility model relates to the field of hydraulic supports, and more specifically, to a front beam telescopic beam and a hydraulic support. Background Technology

[0002] Hydraulic supports are crucial support equipment in fully mechanized mining faces. During operation, a reasonable beam end distance can prevent the hydraulic supports from being too close to the coal face, thus avoiding safety hazards. It also ensures the normal operation and working space of the mining equipment. For conditions prone to roof collapse or coal face spalling, a structure with an integral top beam containing an internal telescopic beam or a hinged front beam containing a telescopic beam is typically used to effectively prevent these problems. To accommodate the mining machine's "travel space," the front beam section is designed with a thinner box body than the top beam. In actual working conditions, due to face inclination or asynchronous force distribution on the two telescopic jacks, the telescopic beam often shifts, deforms, or jams within the front beam. In existing technology, for internal telescopic beam structures, to ensure the strength of the front beam, only a small notch can be made at the front beam cover plate to expose the joint seat and hinge pin. Consequently, repair and replacement are extremely difficult when the telescopic beam jacks malfunction.

[0003] Therefore, a lighter, stronger, and easier-to-maintain front beam telescopic beam and hydraulic support has become an urgent problem to be solved. Utility Model Content

[0004] Therefore, the first objective of this utility model is to provide a front beam telescopic beam.

[0005] The second objective of this utility model is to provide a hydraulic support.

[0006] In view of the above, the first aspect of the present invention provides a front beam telescopic beam, comprising: a front beam; a base plate, one end of which is fixedly connected to the front beam, the base plate including at least one guide member; at least one telescopic beam, the telescopic beam corresponding to the guide member, the telescopic beam being disposed within the guide member and slidably connected to the guide member, the telescopic beam having a U-shaped cross-section; a telescopic member, parallel to the base plate, disposed on the side of the base plate away from the guide member, the telescopic member being slidably connected to the base plate; and a side guard assembly, slidably connected to the base plate.

[0007] In this design, the front beam telescopic beam structure, through the inclusion of a base plate, guide components, telescopic beam, telescopic components, and side protection components, achieves efficient telescopic function of the hydraulic support's front beam. The telescopic beam has a U-shaped cross-section; this structural design not only ensures stable sliding of the telescopic beam within the guide components but also improves its bending resistance and overall rigidity. Simultaneously, the sliding connection between the telescopic components and the base plate makes the telescopic movement smoother, reducing jamming problems caused by structural complexity. Furthermore, the sliding connection design between the side protection components and the base plate further enhances the adaptability and stability of the hydraulic support under complex working conditions. In practical applications, this structure effectively avoids the "rock trapping" problem common in traditional built-in telescopic beam structures, while reducing the risk of damage due to telescopic deformation, thus improving the service life and reliability of the hydraulic support. Overall, this technical solution achieves a balance between lightweight and high strength through optimized structural design, providing a superior solution for the application of hydraulic supports in fully mechanized mining faces.

[0008] In some possible designs, a reinforcing plate is provided at the end of the guide member away from the front beam, and the reinforcing plate is provided with a clearance groove; the side guard assembly includes a side guard plate, wherein at least one main reinforcement is provided on the side guard plate, and the main reinforcement is provided in correspondence with the clearance groove.

[0009] In this design, a reinforcing plate is installed at the end of the guide member furthest from the front beam, and an avoidance groove is provided on the reinforcing plate. This design not only enhances the structural strength of the guide member but also provides space for the movement of the side protection assembly, avoiding interference between the side protection plate and the guide member. The side protection plate in the side protection assembly is equipped with main ribs, which are correspondingly positioned with the avoidance groove, ensuring that the side protection plate remains parallel to the front beam when retracted. This significantly increases the working space of the coal mining machine and effectively avoids the "roof cutting" problem. This improvement not only enhances the overall performance of the hydraulic support but also improves the safety and efficiency of coal mining operations. Through this ingenious structural design, the hydraulic support can better adapt to changes in the roof and coal face under complex working conditions, while reducing equipment maintenance costs and repair difficulty.

[0010] In some possible designs, the side guard assembly also includes a side guard cylinder and a support beam; the support beam includes a U-shaped seat; one end of the side guard cylinder is hinged to the U-shaped seat, and the other end of the side guard cylinder is hinged to the side guard plate.

[0011] In this design, the U-shaped support structure of the support beam, through the hinged connection between the support beam and the side-protection cylinder, enables the flexible opening and closing of the side-protection plate. The extension and retraction of the side-protection cylinder is transmitted to the side-protection plate via the U-shaped support, allowing the side-protection plate to quickly expand or retract when needed, thus better adapting to changes in the roof and coal face and providing a more reliable support effect. Furthermore, the support beam design not only provides stable support for the side-protection cylinder but also enhances the overall stability of the hydraulic support through its structural characteristics. This improvement allows the hydraulic support to adjust its support posture more flexibly in complex coal mining environments, effectively preventing coal face spalling and roof collapse, and improving the support performance and safety of the hydraulic support.

[0012] In some possible designs, the support beam includes at least one first guide plate; at least one first slide rail is also provided on the base plate, with the first guide plate and the first slide rail corresponding one to one.

[0013] In this design, the use of a first guide plate and a first slide rail makes the movement of the support beam on the base plate smoother and more precise, reducing equipment failures caused by uneven beam movement. The cooperation between the first guide plate and the first slide rail not only improves the movement accuracy of the support beam but also enhances its resistance to deformation, further improving the overall stability of the hydraulic support. Through this optimized design, the hydraulic support can maintain better balance during the extension and retraction of the telescopic beam, reducing jamming problems caused by structural deformation. Furthermore, this structural design facilitates the modular design of the hydraulic support, making equipment assembly and maintenance more efficient. Overall, this improvement significantly enhances the reliability and service life of the hydraulic support.

[0014] In some possible designs, the support beam includes a first ear plate; the side guard plate is hinged to the first ear plate.

[0015] In this design, a stable connection between the side guard plate and the support beam is achieved by installing a first ear plate on the support beam and hinged to the first ear plate. This design not only improves the movement flexibility of the side guard plate but also enhances its stability under complex working conditions. Through the hinged relationship of the first ear plate, the side guard plate can be deployed and retracted more smoothly, reducing equipment failures caused by unstable connections. Furthermore, this structural design facilitates the modular design of the hydraulic support, making equipment assembly and maintenance more efficient. Overall, this improvement significantly enhances the reliability and service life of the hydraulic support, while also improving the safety and efficiency of coal mining operations.

[0016] In some possible designs, the front beam telescopic beam also includes: at least one telescopic cylinder, one end of which is hinged to the telescopic component, and the other end of which is fixed to the front beam.

[0017] In this design, the telescopic cylinder provides power support for the telescopic beam's extension and retraction, making its movement smoother and more reliable. By hinged one end of the telescopic cylinder to the telescopic component and fixing the other end to the front beam, this design not only improves the precision of the extension and retraction but also enhances the overall stability of the hydraulic support. Furthermore, the use of the telescopic cylinder facilitates the automated control of the hydraulic support, enabling the equipment to better adapt to the demands of coal mining under complex conditions. Overall, this improvement significantly enhances the reliability and service life of the hydraulic support, while simultaneously increasing the efficiency and safety of coal mining operations.

[0018] In some possible designs, the telescopic component is provided with at least one second ear plate, the telescopic beam is connected to the second ear plate, and the telescopic beam and the second ear plate correspond one-to-one.

[0019] In this design, a stable connection between the telescopic beam and the telescopic component is achieved by installing a second ear plate on the telescopic component and connecting the telescopic beam to the second ear plate. This design not only improves the motion accuracy of the telescopic beam but also enhances its stability under complex working conditions. Through the connection of the second ear plate, the telescopic beam can slide more smoothly within the guide component, reducing equipment failures caused by unstable connections. Furthermore, this structural design facilitates the modular design of the hydraulic support, making equipment assembly and maintenance more efficient. Overall, this improvement significantly enhances the reliability and service life of the hydraulic support, while also improving the efficiency and safety of coal mining operations.

[0020] In some possible designs, the base plate also includes two second slides, the direction of which is parallel to the direction of which the guide is set, and the two second slides are respectively set on the edges of the two sides of the base plate; the telescopic component also includes two second guide plates, the second guide plates being set corresponding to the second slides.

[0021] In this design, a second slide rail is installed on the base plate, and a corresponding second guide plate is installed on the telescopic component, achieving stable sliding of the telescopic component on the base plate. This design not only improves the motion accuracy of the telescopic component but also enhances the overall stability of the hydraulic support. The cooperation between the second slide rail and the second guide plate allows the telescopic component to maintain better balance during movement, reducing jamming problems caused by structural deformation. Furthermore, this structural design facilitates the modular design of the hydraulic support, making equipment assembly and maintenance more efficient. Overall, this improvement significantly enhances the reliability and service life of the hydraulic support, while also improving the efficiency and safety of coal mining operations.

[0022] In some possible designs, the telescopic beam also includes an internal reinforcing plate.

[0023] In this design, the bending resistance and overall rigidity of the telescopic beam are significantly improved by incorporating an internal reinforcing plate. This design not only enhances the stability of the telescopic beam under complex working conditions but also reduces jamming problems caused by structural deformation. The use of the internal reinforcing plate allows the telescopic beam to maintain better structural integrity when bearing large loads, thereby extending the service life of the hydraulic support. Furthermore, this structural design supports the lightweight design of the hydraulic support, reducing the weight of the equipment while ensuring support strength, thus improving the efficiency of transportation and installation. Overall, this improvement significantly enhances the reliability and service life of the hydraulic support, while also improving the efficiency and safety of coal mining operations.

[0036] 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.

[0037] The first aspect of this utility model provides a front telescopic beam, such as... Figure 1 , Figure 2 and Figure 3 As shown, the front telescopic beam includes: a front beam 1; a base plate 2, one end of which is fixedly connected to the front beam 1, the base plate 2 including at least one guide member 21; at least one telescopic beam 3, the telescopic beam 3 corresponding to the guide member 21, the telescopic beam 3 being disposed within the guide member 21, the telescopic beam 3 being slidably connected to the guide member 21, the cross section of the telescopic beam 3 being U-shaped; a telescopic member 4, which is parallel to the base plate 2, the telescopic member 4 being disposed on the side of the base plate 2 away from the guide member 21, the telescopic member 4 being slidably connected to the base plate 2; and a side guard assembly 5, which is slidably connected to the base plate 2.

[0038] In this embodiment, the front beam telescopic beam structure, through the arrangement of a base plate 2, guide member 21, telescopic beam 3, telescopic member 4, and side protection assembly 5, achieves the efficient telescopic function of the front beam 1 of the hydraulic support. The telescopic beam 3 has a U-shaped cross-section; this structural design not only ensures stable sliding of the telescopic beam 3 within the guide member 21 but also improves its bending resistance and overall rigidity. Simultaneously, the sliding connection between the telescopic member 4 and the base plate 2 makes the telescopic movement smoother, reducing jamming problems caused by structural complexity. Furthermore, the sliding connection design between the side protection assembly 5 and the base plate 2 further enhances the adaptability and stability of the hydraulic support under complex working conditions. In practical applications, this structure effectively avoids the "rock trapping" problem common in traditional built-in telescopic beam 3 structures, while reducing the risk of damage due to telescopic deformation, thus improving the service life and reliability of the hydraulic support. Overall, this technical solution, through optimized structural design, achieves a balance between lightweight and high strength, providing a superior solution for the application of hydraulic supports in fully mechanized mining faces.

[0039] In some possible embodiments, a reinforcing plate 22 is provided at the end of the guide member 21 away from the front beam 1, and the reinforcing plate 22 is provided with a relief groove 23; the side guard assembly 5 includes a side guard plate 51, wherein at least one main rib 52 is provided on the side guard plate 51, and the main rib 52 is correspondingly provided with the relief groove 23.

[0040] In this embodiment, a reinforcing plate 22 is provided at the end of the guide member 21 away from the front beam 1, and an avoidance groove 23 is provided on the reinforcing plate 22. This design not only enhances the structural strength of the guide member 21, but also provides space for the movement of the side support assembly 5, avoiding interference between the side support plate 51 and the guide member 21. The side support plate 51 in the side support assembly 5 is provided with main reinforcing bars 52, which are correspondingly arranged with the avoidance groove 23, so that the side support plate 51 can remain parallel to the front beam 1 when retracted, thereby significantly increasing the travel space of the coal mining machine and effectively avoiding the "roof cutting" problem. This improvement not only enhances the overall performance of the hydraulic support, but also improves the safety and efficiency of coal mining operations. Through this ingenious structural design, the hydraulic support can better adapt to changes in the roof and coal wall under complex working conditions, while reducing equipment maintenance costs and repair difficulty.

[0041] In some possible embodiments, the side guard assembly 5 further includes a side guard cylinder 53 and a support beam 54; the support beam 54 includes a U-shaped seat 55; one end of the side guard cylinder 53 is hinged to the U-shaped seat 55, and the other end of the side guard cylinder 53 is hinged to the side guard plate 51.

[0042] In this embodiment, the U-shaped seat 55 structure of the support beam 54, through the hinged connection between the support beam 54 and the support beam 53, enables the flexible opening and closing of the support plate 51. The extension and retraction movement of the support cylinder 53 is transmitted to the support plate 51 through the U-shaped seat 55, allowing the support plate 51 to quickly expand or retract when needed, thereby better adapting to changes in the roof and coal wall and providing a more reliable support effect. Furthermore, the design of the support beam 54 not only provides stable support for the support cylinder 53 but also enhances the overall stability of the hydraulic support through its structural characteristics. This improvement allows the hydraulic support to adjust its support posture more flexibly in complex coal mining environments, effectively preventing coal wall spalling and roof collapse, and improving the support performance and safety of the hydraulic support.

[0043] In some possible embodiments, the support beam 54 includes at least one first guide plate 56; the base plate 2 is also provided with at least one first slide rail 24, and the first guide plate 56 corresponds one-to-one with the first slide rail 24.

[0044] In this embodiment, such as Figure 3 and Figure 6 As shown, the design using the first guide plate 56 and the first slide rail 24 makes the movement of the support beam 54 on the base plate 2 smoother and more precise, reducing equipment failures caused by poor movement of the support beam 54. The cooperation between the first guide plate 56 and the first slide rail 24 not only improves the movement accuracy of the support beam 54, but also enhances its resistance to deformation, further improving the overall stability of the hydraulic support. Through this optimized design, the hydraulic support can maintain better balance during the extension and retraction of the telescopic beam 3, reducing jamming problems caused by structural deformation. In addition, this structural design also facilitates the modular design of the hydraulic support, making equipment assembly and maintenance more efficient. Overall, this improvement significantly enhances the reliability and service life of the hydraulic support.

[0045] In some possible embodiments, the support beam 54 includes a first ear plate 57; the side guard plate 51 is hinged to the first ear plate 57.

[0046] In this embodiment, such as Figure 6 As shown, by setting a first ear plate 57 on the support beam 54 and hinged the side guard plate 51 to the first ear plate 57, a stable connection between the side guard plate 51 and the support beam 54 is achieved. This design not only improves the movement flexibility of the side guard plate 51 but also enhances its stability under complex working conditions. Through the hinged relationship of the first ear plate 57, the side guard plate 51 can be deployed and retracted more smoothly, reducing equipment failures caused by unstable connections.

[0047] In some possible embodiments, the front beam telescopic beam further includes at least one telescopic cylinder 6, one end of which is hinged to the telescopic member 4, and the other end of which is fixed to the front beam 1.

[0048] In this embodiment, the telescopic cylinder 6 provides power support for the telescopic beam 3's extension and retraction, making its movement smoother and more reliable. By hinged one end of the telescopic cylinder 6 to the telescopic component 4 and fixing the other end to the front beam 1, this design not only improves the accuracy of the extension and retraction but also enhances the overall stability of the hydraulic support. Furthermore, the use of the telescopic cylinder 6 facilitates the automated control of the hydraulic support, enabling the equipment to better adapt to the coal mining needs under complex working conditions. Overall, this improvement significantly enhances the reliability and service life of the hydraulic support, while also increasing the efficiency and safety of coal mining operations.

[0049] In some possible embodiments, the telescopic member 4 is provided with at least one second ear plate 41, the telescopic beam 3 is connected to the second ear plate 41, and the telescopic beam 3 and the second ear plate 41 correspond one-to-one.

[0050] In this embodiment, such as Figure 1 and Figure 4 As shown, by setting a second ear plate 41 on the telescopic member 4 and connecting the telescopic beam 3 to the second ear plate 41, a stable connection between the telescopic beam 3 and the telescopic member 4 is achieved. This design not only improves the motion accuracy of the telescopic beam 3 but also enhances its stability under complex working conditions. Through the connection relationship of the second ear plate 41, the telescopic beam 3 can slide more smoothly within the guide member 21, reducing equipment failures caused by unstable connections. In addition, this structural design also facilitates the modular design of the hydraulic support, making equipment assembly and maintenance more efficient. Overall, this improvement significantly enhances the reliability and service life of the hydraulic support, while also improving the efficiency and safety of coal mining operations.

[0051] In some possible embodiments, the base plate 2 further includes two second slide rails 25, the direction of the second slide rails 25 being parallel to the direction of the guide member 21, and the two second slide rails 25 being respectively disposed on the edges of both sides of the base plate 2; the telescopic member 4 further includes two second guide plates 42, the second guide plates 42 being disposed corresponding to the second slide rails 25.

[0052] In this embodiment, by setting a second slide rail 25 on the base plate 2 and a corresponding second guide plate 42 on the telescopic member 4, stable sliding of the telescopic member 4 on the base plate 2 is achieved. This design not only improves the motion accuracy of the telescopic member 4 but also enhances the overall stability of the hydraulic support. The cooperation between the second slide rail 25 and the second guide plate 42 allows the telescopic member 4 to maintain better balance during movement, reducing jamming problems caused by structural deformation. Furthermore, this structural design facilitates the modular design of the hydraulic support, making equipment assembly and maintenance more efficient. Overall, this improvement significantly enhances the reliability and service life of the hydraulic support, while also improving the efficiency and safety of coal mining operations.

[0053] In some possible embodiments, the telescopic beam 3 also includes an inner reinforcing plate 31.

[0054] In this embodiment, such as Figure 2 and Figure 5 As shown, by incorporating an inner reinforcing plate 31 within the telescopic beam 3, the bending resistance and overall rigidity of the telescopic beam 3 are significantly improved. This design not only enhances the stability of the telescopic beam 3 under complex working conditions but also reduces jamming problems caused by structural deformation. The use of the inner reinforcing plate 31 allows the telescopic beam 3 to maintain better structural integrity when subjected to large loads, thereby extending the service life of the hydraulic support. Furthermore, this structural design supports the lightweight design of the hydraulic support, reducing the weight of the equipment while ensuring support strength, thus improving the efficiency of equipment transportation and installation. Overall, this improvement significantly enhances the reliability and service life of the hydraulic support, while also improving the efficiency and safety of coal mining operations.

[0055] In some possible embodiments, the front beam 1 is hinged to the overall top beam and the front beam 1 jack via two sets of ear plates welded to the tail upright plate. Three sets of guide-stabilizing hollow steel sections are welded to the bottom plate 2, providing good guiding performance. Slides are provided on the inner sides of the three sets of hollow steel sections. A reinforcing plate 22 is welded to the front of the hollow steel sections, and an avoidance groove 23 is cut into it. When the side guard plate 51 is fully retracted, the corresponding main reinforcement 52 can be embedded in the corresponding groove, achieving parallelism between the side guard plate 51 and the front beam 1. Compared to ordinary structures, this provides a larger travel space for the coal mining machine, thus avoiding the "roof cutting" problem. The front beam 1 has slides on its outer side and a welded box structure on its inner side, providing higher resistance to deformation.

[0056] The telescopic beam 3 is composed of telescopic components, the main body of which is also a hollow steel section with a reinforcing plate 22 welded inside, and a pin hole at the front. The three telescopic components are inserted into the hollow steel section of the front beam 1. The guide grooves on both sides of the telescopic components are inserted into the upper slide rails of the front beam 1. The three sets of ear plates are connected to the three sets of telescopic components via pins. The piston rod side of the telescopic jack is connected to the fixed seat via a pin, and the cylinder bottom side is connected to the ear plate on the front beam 1 via a pin. The telescopic beam 3 opens and retracts by extending and retracting the telescopic jack. The telescopic beam 3 is a single-piece structure, which avoids the "clamping" problem compared to the three-section structure of ordinary telescopic beams 3.

[0057] The support beam 54 has a U-shaped seat 55 at the rear and an ear plate at the front. The guide plate is inserted into the slide of the front beam 1 on both sides. Inside the slide, the bottom of the side jack cylinder is hinged to the U-shaped seat 55. The piston rod is hinged to the side plate 51 through a small four-bar linkage. When the telescopic jack is opened, it drives the support beam 54 to achieve telescopic movement. The telescopic movement of the side jack realizes the opening and retraction of the side plate 51.

[0058] In this application, the front beam telescopic beam, with the same box height and mass, has a larger bending safety factor, reducing the problem of damage due to telescopic deformation; it also provides more walking space for the coal mining machine, avoiding the "roof cutting" problem; and it avoids the "rock trapping" problem of the built-in telescopic beam 3 structure.
