Technical Field

[0001] This utility model relates to the field of tunnel support technology, specifically a hydraulic support structure for tunnel support. Background Technology

[0002] Hydraulic supports are important equipment used in coal mines to support and protect roadways. They bear the heavy responsibility of supporting the roof of the coal mining face and maintaining a safe working space, preventing roadway deformation and damage, and ensuring a safe working space for workers and equipment. They are of great significance to coal mine safety production, increasing face output, reducing labor intensity and improving labor efficiency.

[0003] However, harsh tunnel working conditions and complex geological environments can easily cause hydraulic supports to tilt and experience uneven stress, making existing hydraulic supports unable to adapt to different tunnel geological conditions, especially unable to effectively support the tunnel sidewalls. This seriously affects the timely support and effective roof support of hydraulic supports, thereby reducing the coordination between tunneling and support and the efficiency of tunnel excavation.

[0004] Therefore, we propose a hydraulic support structure for roadway support to solve the above problems. Utility Model Content

[0016] 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. Example

[0017] like Figure 1-4 As shown in the figure, an embodiment of the present invention provides a hydraulic support structure for roadway support, including an installation platform 1, an adjustable hydraulic support 3 at the top of the installation platform 1, and an extension device 4 at the movable end of the adjustable hydraulic support 3.

[0018] The adjustable hydraulic support 3 includes two hinge seats 301, and a flip cover 303 is rotatably connected between the two hinge seats 301. An inner plate 304 is fixedly installed on the inner side of the flip cover 303. A hydraulic cylinder 305 is hinged to the bottom end of the inner plate 304 and a connecting rod 307 is fixedly connected thereto. An installation groove 308 is opened at the top end of the flip cover 303.

[0019] like Figure 2 As shown, in some embodiments, a control panel 2 is fixedly installed on the top of the mounting platform 1. The control panel 2 is located below the adjustable hydraulic support 3 and is electrically connected to the adjustable hydraulic support 3 and the extension device 4.

[0020] Specifically, the control panel 2 can receive external operation commands and convert them into electrical signals, which are then transmitted to the adjustable hydraulic support 3 and the extension device 4, thereby controlling the working status of the adjustable hydraulic support 3 and the extension device 4.

[0021] like Figure 2 As shown, in some embodiments, a connecting crossbar 302 is fixedly installed between two hinge seats 301, and the bottom end of the hinge seat 301 is fixedly connected to the top end of the mounting platform 1.

[0022] Specifically, the connecting crossbar 302 enhances the structural stability between the two hinge seats 301, ensuring the smoothness and reliability of the flip cover 303 during the deflection process.

[0023] Meanwhile, the connecting crossbar 302 also provides additional support, which helps to resist the pressure from the roadway sidewall and further improves the overall stability of the support structure.

[0024] like Figure 3As shown, in some embodiments, two locking structures 309 are fixedly installed at the top of the mounting platform 1. Each locking structure 309 includes a support column 310. An electric push rod 311 and a locking hook 312 are hinged to the back side of the support column 310. The movable end of the electric push rod 311 is hinged to the bottom end of the locking hook 312. The initial state of the connecting rod 307 is engaged with the locking hook 312.

[0025] Specifically, when the hydraulic cylinder 305 is in the retracted state, the connecting rod 307 engages with the locking hook 312, so that the flip cover 303 remains in a horizontal lifting state, stably supporting the roadway roof.

[0026] like Figure 2 As shown, in some embodiments, the bottom end of the hydraulic cylinder 305 is hinged to a connecting seat 306, and the bottom end of the connecting seat 306 is fixedly connected to the top end of the mounting platform 1.

[0027] Specifically, the connecting seat 306 not only provides stable support for the hydraulic cylinder 305, but also ensures the smoothness and accuracy of the hydraulic cylinder 305 during extension and retraction. The hydraulic cylinder 305 is connected to the connecting seat 306 by a hinge, allowing the hydraulic cylinder 305 to be flexibly adjusted within a certain range, thereby better adapting to the needs of roadway support.

[0028] like Figure 4 As shown, in some embodiments, the extension device 4 includes an inner seat 401, which is fixedly connected to the inner wall of the mounting groove 308. An electric telescopic rod 402 is fixedly installed on the inner side of the inner seat 401. The movable end of the electric telescopic rod 402 extends to the outer side of the inner seat 401 and is fixedly connected to a lifting plate 403. An abutment plate 405 is hinged to the top of the lifting plate 403.

[0029] Specifically, after the hydraulic cylinder 305 drives the tilting cover 303 to deflect to a suitable angle, the operator can control the extension and retraction of the electric telescopic rod 402 through the control panel 2, thereby driving the lifting plate 403 and the contact plate 405 to move up and down. The adjustment of the lifting of the contact plate 405 can make it fit more tightly against the roadway sidewall, further enhancing the stability and support effect of the support structure.

[0030] like Figure 4 As shown, in some embodiments, the side end of the lifting plate 403 is hinged with a folding member 404, and the bottom end of the folding member 404 is hinged to the surface of the inner seat 401.

[0031] Specifically, the design of the folding component 404 increases the flexibility and adaptability of the lifting plate 403. During lifting, the folding component 404 can be slightly adjusted at an angle according to the shape of the roadway sidewall, thereby achieving appropriate folding and unfolding. This ensures that the lifting plate 403 and the contact plate 405 can conform to the roadway sidewall, maintaining good support even when facing irregular or uneven roadway surfaces. This design not only improves the stability of the support structure but also enhances its adaptability to complex geological conditions.

[0032] In addition, the hinged connection of the folding component 404 allows it to distribute stress when subjected to force, reducing stress concentration in a single part and thus extending the service life of the overall structure.

[0033] When in use, when the roadway needs to be supported, the hydraulic support structure is first moved to the designated position. When the angle of the flip cover 303 needs to be adjusted to adapt to different roadway geological conditions, the control panel 2 sends a signal to the electric push rod 311. The electric push rod 311 pushes the locking hook 312 to rotate around the support column 310, unlocking the connecting rod 307. At this time, the hydraulic cylinder 305 can extend and retract freely. The operator can then input operating commands through the control panel 2 to control the extension and retraction of the hydraulic cylinder 305, thereby driving the flip cover 303 to rotate around the hinge seat 301 to adapt to the inclination angle of the roadway or the roof at different heights.

[0034] After the flip cover 303 is tilted to the appropriate position, the extension device 4 begins to play its crucial role. The operator controls the extension length of the electric telescopic rod 402 through the control panel 2, which drives the lifting plate 403 and the contact plate 405 to rise or fall until the contact plate 405 is tightly attached to the sidewall of the tunnel.

[0035] Meanwhile, the folding component 404 also plays an important role in the lifting process. It can make fine adjustments according to the shape of the tunnel sidewall to ensure that the lifting plate 403 and the contact plate 405 always remain in close contact with the tunnel sidewall.

[0036] In summary, by using the adjustable hydraulic support 3 and the expansion device 4, the hydraulic cylinder 305 can drive the flip cover 303 to rotate around the hinge seat 301, causing the flip cover 303 to change from a horizontal lifting state to an inclined overlapping state. In conjunction with the expansion device 4, the contact plate 405 can fit more closely to the sidewall of the roadway, significantly improving the stability of the support structure and its effectiveness in practical applications, ensuring that it can play the best support role in various complex environments.

[0037] It should be noted that the specific models and specifications of the control panel 2, hydraulic cylinder 305, electric push rod 311, and electric telescopic rod 402 in the hydraulic support structure for roadway support need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0038] Furthermore, the power supply and operating principle of the control panel 2, hydraulic cylinder 305, electric push rod 311, and electric telescopic rod 402 in the hydraulic support structure for tunnel support are clear to those skilled in the art, and will not be described in detail here.

[0039] Furthermore, the working principles and wiring methods of the control panel 2, hydraulic cylinder 305, electric push rod 311, and electric telescopic rod 402 in the hydraulic support structure for tunnel support are commonplace and belong to conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
