[0027] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0028] The hydraulic support 100 with a working platform according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0029] like Figure 1-4 As shown, a hydraulic support 100 with a working platform according to an embodiment of the present invention includes a hydraulic support 1 and a working platform 2 .

[0030] The hydraulic support 1 includes a base 11, a hydraulic telescopic member 12, a top beam 13, a connecting rod 14 and a shielding beam 15. The hydraulic telescopic member 12 is arranged on the base 11 and can telescopically move relative to the base 11 in the up-down direction. The top beam 13 is arranged on the hydraulic telescopic member 12 so that the hydraulic telescopic member 12 drives the top beam 13 to move in the up-down direction. The upper end of the shielding beam 15 is rotatably connected to the top beam 13, and the lower end of the shielding beam 15 is rotatably connected to the base 11 through the connecting rod 14. Specifically, Figure 1 and Figure 2 As shown, the base 11 serves as a stable foundation for the entire hydraulic support and is made of high-strength steel to ensure that it can remain stable in a complex and changeable mine environment. The hydraulic telescopic member 12 is fixed on the base 11 and the hydraulic telescopic member 12 can be fed with hydraulic oil to telescope in the up and down directions on the base 11. As a key component that directly contacts the tunnel roof and bears the pressure thereon, the top beam 13 is installed at the upper end of the hydraulic telescopic member 12. The top beam 13 is driven by the hydraulic telescopic member 12 to move in the up and down directions, thereby achieving effective support and adjustment of the tunnel roof, thereby ensuring the safety and stability of the working surface. The upper end of the shielding beam 15 is rotatably connected to the top beam 13 through a hinge mechanism, and can maintain synchronous tilt adjustment when the top beam 13 moves, effectively dispersing and resisting the pressure from the roof. The lower end of the shielding beam 15 is connected to the base 11 through a connecting rod 14 structure, and a rotatable connection is adopted between the shielding beam 15 and the base 11, so that the shielding beam 15 can have a certain adaptive deformation ability while maintaining structural stability, so as to better adapt to complex and changeable roof conditions.

[0031] The working platform 2 is arranged on the shielding beam 15 and between the shielding beam 15 and the hydraulic telescopic member 12. The working platform 2 has a retracted state and a supporting state. When the hydraulic support 1 is being repaired, the working platform 2 is in the supporting state so that the repair personnel can repair through the working platform 2. When the hydraulic support 1 is retracted, the working platform 2 is in the retracted state. Specifically, Figure 1 and Figure 2As shown, the working platform 2 is arranged on the shielding beam 15 and is located between the shielding beam 15 and the hydraulic telescopic member 12. Without affecting the operation of the hydraulic support 1, the internal space structure of the hydraulic support 1 is fully utilized. When the hydraulic support 1 is undergoing routine inspection or maintenance, when the working platform 2 switches to the supporting state, the supporting structure of the working platform 2 can stably bear the weight of the maintenance personnel and provide a safe working environment, so that the maintenance personnel can conduct detailed inspection, maintenance or replacement of each key part of the hydraulic support 1 through the working platform 2, thereby effectively improving the inspection efficiency and operation safety. When the hydraulic support 1 needs to be retracted to adapt to the change in the mining depth of the mine, or to carry out operations such as transportation and installation, the working platform 2 quickly switches to the retracted state, and the working platform 2 reduces its occupied space, ensuring that the hydraulic support 1 can smoothly and compactly complete the retraction action, avoiding unnecessary structural interference and safety hazards.

[0032] The hydraulic support with a working platform in the embodiment of the present invention is provided with a hydraulic support 1 and a working platform 2. The working platform 2 provides a reliable working platform 2 for the inspection and maintenance of the hydraulic support 1, thereby ensuring the safety of the operating personnel, improving the inspection efficiency and safety performance of the maintenance personnel, and effectively promoting the promotion and use of the ultra-large mining height hydraulic support 1 and the ultra-large mining height mining technology.

[0033] In some embodiments, the hydraulic support 1 provides reliable support for high-altitude operations during maintenance without affecting the propulsion action of the hydraulic support 1 .

[0034] The working platform 2 includes a first supporting frame 21 , a second supporting frame 22 and a supporting plate 23 .

[0035] The two ends of the first support frame 21 are rotatably connected to the shielding beam 15 and the second support frame 22, respectively, and one end of the second support frame 22 is rotatably connected to the connecting rod 14. Figure 1-Figure 4 As shown, the right end of the first support frame 21 is hinged on the shielding beam 15, the left end of the first support frame 21 is hinged on the middle part of the second support frame 22, and the left end of the second support frame 22 is hinged on the connecting rod 14 of the hydraulic support 1, so that the first support frame 21 and the second support frame 22 are roughly formed in a herringbone shape. The first support frame 21, the second support frame 22, the shielding beam 15 and the connecting rod 14 form a four-link 14 mechanism. When the hydraulic support 1 is folded, the right end of the first support frame 21 and the right end of the second support frame 22 are close to each other, so that the first support frame 21 and the second support frame 22 are folded. When the hydraulic support 1 is extended, the right end of the first support frame 21 and the right end of the second support frame 22 are away from each other, so that the first support frame 21 and the second support frame 22 are opened.

[0036] The support plate 23 is rotatably connected to the other end of the second support frame 22 and has a horizontal position and a vertical position relative to the second support frame 22. When the working platform 2 is in a retracted state, the support plate 23 is in a vertical position, and when the working platform 2 is in a supporting state, the support plate 23 is in a horizontal position. Figure 1-Figure 4 As shown, the support plate 23 is a horizontal plate used to provide support or a working surface. The left end of the support plate 23 is connected to the left end of the second support frame 22. When the working platform 2 is in a retracted state, the first support frame 21 and the second support frame 22 are retracted to drive the support plate 23 to rotate to a vertical position. When the working platform 2 is in a supporting state, the first support frame 21 and the second support frame 22 are opened to drive the support plate 23 to a horizontal position, so that the second support frame 22 supports the support plate 23.

[0037] In some embodiments, the working platform 2 further includes a telescopic member 24, which is disposed below the second supporting member and whose two ends are respectively connected to the second telescopic member 24 and the supporting plate 23, so that the telescopic member 24 drives the supporting plate 23 to rotate between the horizontal position and the vertical position. Figure 3 and Figure 4 As shown, the telescopic member 24 can be a hydraulic cylinder, an electric push rod, etc. The telescopic member 24 is arranged below the support plate 23. The left end of the telescopic member 24 is hinged to the lower end surface of the support member, and the right end of the telescopic member 24 is hinged to the second support member. When the working platform 2 is in a retracted state, the telescopic member 24 extends to drive the support plate 23 to rotate to a vertical position. When the working platform 2 is in a supporting state, the telescopic member 24 shortens to drive the support plate 23 to rotate to a horizontal position. As a result, the support plate 23 remains stable under the joint support of the second support member and the telescopic member 24, so as to provide stable support for maintenance personnel.

[0038] In addition, when the hydraulic support 1 is working, it is subjected to the pressure of the overlying rock strata. When the pressure exceeds the rated working pressure of the safety valve of the hydraulic support 1, the safety valve of the hydraulic support 1 starts to relieve pressure, and the height of the top beam 13 is reduced. During this process, the working platform 2 is deformed accordingly, which does not affect the movement of the hydraulic support 1.

[0039] In some embodiments, the second support frame 22 includes a first rod 221, a second rod 222 and a plurality of third rods 223, the first rod 221 and the second rod 222 are arranged opposite to each other along the width direction of the hydraulic support 1, the two ends of the first rod 221 are rotatably connected to the support plate 23 and the connecting rod 14, the two ends of the second rod 222 are rotatably connected to the support plate 23 and the connecting rod 14, and the plurality of third rods 223 are arranged between the first rod 221 and the second rod 222 and are arranged at intervals along the length direction of the first rod 221. Specifically, as Figure 4As shown, the first rod 221 and the second rod 222 are both vertical rods, the third rod 223 is a horizontal rod, the first rod 221 and the second rod 222 are arranged relative to each other in the front-to-back direction, and the left end of the first support frame 21 is hinged to the middle of the first rod 221 and the second rod 222 respectively, and multiple third rods 223 are arranged between the first rod 221 and the second rod 222 and are arranged at intervals along the length direction of the first rod 221, so that the second support frame 22 is ladder-shaped, which not only provides a stable support for the support plate 23, but also provides a safe climbing path for maintenance personnel, thereby improving maintenance efficiency.

[0040] In some embodiments, the hydraulic support 100 with a working platform further includes a fence 25, which is disposed on the support plate 23 and extends along the circumference of the support plate 23. Specifically, Figure 1-Figure 4 As shown, the fence 25 is made of a strong and durable material, such as steel or alloy material. The fence 25 surrounds the circumference of the support plate 23. During the operation, maintenance personnel or operators will perform various operations on the support plate 23. The existence of the fence 25 provides them with a safe working environment to prevent people or objects from accidentally falling from the support plate 23.

[0041] In some embodiments, in the supporting state, the support plate 23 abuts against the hydraulic telescopic member 12. Specifically, Figure 1 As shown, when the working platform 2 is in a supporting state, the supporting plate 23 is in a horizontal position and the left side of the supporting plate 23 is against the circumferential surface of the hydraulic telescopic member 12, thereby not only providing additional supporting force for the supporting plate 23, but also preventing the supporting plate 23 from shaking or tilting due to uneven force during operation, thereby improving the stability of the working platform support.

[0042] In some embodiments, the free end of the support plate 23 is provided with a through hole penetrating the support plate 23 in the up-down direction, and in the supporting state, the outer circumference of the hydraulic telescopic member 12 and the inner circumference of the through hole abut against each other. Figure 1-Figure 4 As shown, the left end of the support plate 23 is provided with a through hole which penetrates the support plate 23 in the up and down directions, and the inner circumference of the through hole coincides with the outer circumference of the support plate 23. In the supported state, when the support plate 23 reaches a horizontal position, the inner circumference of the through hole of the support plate 23 abuts against the outer circumference of the hydraulic telescopic component 12, thereby not only ensuring the stability and horizontality of the support plate 23, but also preventing the support plate 23 from shaking or tilting during operation. The cooperation between the through hole and the hydraulic telescopic component 12 can ensure that the working platform 2 will not be misplaced or loosened during operation, thereby improving the safety performance of the working platform 2.

[0043] In some embodiments, the working platform is coated with an anti-corrosion material, thereby extending the service life of the working platform, reducing the frequency of repair and replacement due to corrosion, and thus reducing the maintenance cost of the support platform.

[0044] In some embodiments, the hydraulic telescopic member 12 includes a first hydraulic telescopic member and a second hydraulic telescopic member, both of which are arranged on the base 11 and are connected to the top beam 13. Specifically, the first hydraulic telescopic member and the second hydraulic telescopic member are arranged at intervals along the front-to-back direction, the lower ends of the first hydraulic telescopic member and the second hydraulic telescopic member are arranged on the base 11, and the first hydraulic telescopic member and the second hydraulic telescopic member are connected to the top beam 13. The first hydraulic telescopic member and the second hydraulic telescopic member improve the stability of the hydraulic support 1 and help prevent the top beam 13 from tilting or shaking during the lifting process.
