Description

Technical Field

[0001] This invention relates to the field of tunnel support technology, specifically to a tunnel support device and a transport device. Background Technology

[0002] Currently, in modern mechanized coal mining, the safety support of roadways is a prominent issue. As mining depth increases and geological conditions become more complex, roadways located in special geological structures often become difficult to maintain. One existing method for temporary support of tunneling faces is to use gantry cranes to support the roadway immediately excavated by the tunneling machine. After support is in place, anchor bolts and metal mesh are used to protect the roof and sidewalls to prevent coal chunks from falling and injuring workers. However, this support method requires specialized handling equipment to move the gantry cranes and cannot protect the working face where tunneling is currently underway. Summary of the Invention

[0003] The present invention aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of the present invention propose a roadway support device that can move forward as the working face advances, is easy to move, and has a good support effect.

[0005] Embodiments of the present invention also provide a conveying device.

[0006] The tunnel support equipment of an embodiment of the present invention includes: a portal frame, the portal frame including a connected support beam and two support columns, the two support columns being respectively disposed on both sides of the support beam along its length direction; the portal frame having a working state and a shifting state; in the working state, the support columns are raised to allow the support beam to support the tunnel roof; in the shifting state, the support columns are retracted to separate the support beam from the tunnel roof; and a transport device, the transport device including a support platform, a traveling assembly, and a transport vehicle; the traveling assembly being disposed at the lower end of the support platform and defining an activity space for people and machines to move along with the support platform; the transport vehicle being disposed at the upper end of the support platform; when the portal frame is in the shifting state, the support beam is placed on the transport vehicle, and the transport vehicle is movable along the length direction of the support platform to move the portal frame to a preset position.

[0007] According to an embodiment of the roadway support equipment of the present invention, when it is necessary to move the gantry support, the gantry support can be moved to a shifting state, allowing it to be placed on a transport vehicle. Since the transport vehicle is movable along the length of the support platform, the gantry support can be moved to a preset position, and then moved to the working state to support the roadway roof. Furthermore, since the support platform can travel within the roadway via a walking assembly, it can advance with the roadway excavation face and provide protection for both the roadway and the working face. Therefore, the roadway support equipment of the embodiment of the present invention can move forward with the advancement of the working face, is easy to move, and provides good support.

[0008] In some embodiments, the walking components are in two groups, and the two groups of walking components are respectively arranged on both sides of the support platform in the width direction. Each group of walking components includes at least two walking units, and the two walking units are arranged at intervals along the length direction of the support platform.

[0009] In some embodiments, the walking unit includes a first telescopic column, a second telescopic column, and a third telescopic column. The first and second telescopic columns are arranged at intervals along the length of the support platform. The upper ends of both the first and second telescopic columns are connected to the support platform, and the lower ends of both the first and second telescopic columns can support the tunnel floor. One of the first and second telescopic columns is slidably connected to the support platform along its length, while the other is fixedly connected to the support platform. The third telescopic column extends along the length of the support platform, with one end connected to the first telescopic column and the other end connected to the second telescopic column.

[0010] In some embodiments, the transport device further includes a support assembly, which includes a first support plate and a fourth telescopic column. The fourth telescopic column is located at the front end of the support platform, with its lower end connected to the support platform and its upper end connected to the first support plate. The first support plate is used to support the roof of the roadway.

[0011] In some embodiments, the support assembly further includes a second support plate and a fifth telescopic column. The second support plate is disposed at the front end of the first support plate and is pivotally connected to the first support plate. The fifth telescopic column is disposed at the front end of the support platform. The lower end of the fifth telescopic column is connected to the support platform, and the upper end of the fifth telescopic column is connected to the second support plate. The fifth telescopic column is used to drive the second support plate to swing relative to the first support plate.

[0012] In some embodiments, the gantry frame further includes two telescopic beams, which are respectively disposed on both sides of the length direction of the support beam. The upper end of the support column is connected to the telescopic beams. In the working state, the telescopic beams extend, and in the moving state, the telescopic beams retract.

[0013] In some embodiments, the gantry frame further includes a support shoe pivotally disposed at the lower end of the support column.

[0015] In some embodiments, the tunnel support equipment further includes a control system electrically connected to the gantry frame and the transport device. The control system is used to control the gantry frame to switch between the working state and the moving state, and to control the traveling assembly and the transport vehicle to move forward and backward.

[0017] According to an embodiment of the present invention, when a gantry crane needs to be moved, it can be moved to a shifting state, allowing it to be placed on a transport vehicle. Since the transport vehicle is movable along the length of the support platform, the gantry crane can be moved to a preset position, and then moved to a working state to support the tunnel roof. Furthermore, because the support platform can travel within the tunnel via a walking assembly, it can advance with the tunnel face and provide protection for both the tunnel and the working face. Therefore, the transport device of this embodiment can move forward with the advancement of the working face, is easy to move, and provides good support. Attached Figure Description

Detailed Implementation

[0023] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] The following is a reference appendix. Figure 1 and Figure 2 This invention describes a tunnel support device and a transport apparatus according to embodiments of the present invention.

[0025] like Figure 1 and Figure 2 As shown, the tunnel support equipment according to an embodiment of the present invention includes: a portal frame 1 and a transport device 2. The portal frame 1 includes a connected support beam 11 and two support columns 12, the two support columns 12 being respectively disposed on both sides of the support beam 11 along its length. The portal frame 1 has a working state (e.g., Figure 2 The solid line indicates the gantry frame 1) and the moving state (e.g.) Figure 2 The dotted line indicates the portal frame 1). In the working state, the support column 12 is raised so that the support beam 11 supports the roadway roof. In the shifting state, the support column 12 is retracted so that the support beam 11 is spaced apart from the roadway roof. For example, there can be multiple portal frames 1, which are arranged at intervals along the length of the roadway.

[0026] The handling device 2 includes a support platform 21, a walking component 22, and a handling vehicle 23. The walking component 22 is located at the lower end of the support platform 21 and defines an activity space for people and machines to move around. The handling vehicle 23 is located at the upper end of the support platform 21. When the gantry frame 1 is in the shifting state, the support beam 11 is placed on the handling vehicle 23. The handling vehicle 23 can move along the length of the support platform 21 to move the gantry frame 1 to a preset position.

[0027] According to an embodiment of the roadway support equipment of the present invention, when it is necessary to move the portal frame 1, the portal frame 1 can be moved to a shifting state, so that the portal frame 1 can be placed on the transport vehicle 23. Since the transport vehicle 23 is movable along the length direction of the support platform 21, the portal frame 1 can be moved to a preset position, and then the portal frame 1 can be moved to the working state to support the roadway roof. Furthermore, since the support platform 21 can travel within the roadway via the traveling assembly 22, it can follow the advancement of the roadway excavation face and provide protection for the roadway and the working face. Therefore, the roadway support equipment of the embodiment of the present invention can move forward with the advancement of the working face, is easy to move, and has a good support effect.

[0028] In some embodiments, such as Figure 1 As shown, there are two sets of walking components 22, which are respectively arranged on both sides of the support platform 21 in the width direction. Each set of walking components 22 includes at least two walking units 221, which are spaced apart along the length direction of the support platform 21. By arranging the walking components 22 in the above-described structure, the tunnel support equipment of this embodiment can improve the stability of the movement of the transport device 2. For example, the walking components 22 can be wheeled, tracked, or stepping-type moving structures.

[0029] Specifically, such as Figure 1 As shown, the walking unit 221 includes a first telescopic column 2211, a second telescopic column 2212, and a third telescopic column 2213. The first and second telescopic columns 2211 and 2212 are arranged at intervals along the length of the support platform 21. The upper ends of both the first and second telescopic columns 2211 and 2212 are connected to the support platform 21, and the lower ends of both can support the tunnel floor. One of the first and second telescopic columns 2211 and 2212 is slidably connected to the support platform 21 along its length, while the other is fixedly connected to the support platform 21. The third telescopic column 2213 extends along the length of the support platform 21, with one end connected to the first telescopic column 2211 and the other end connected to the second telescopic column 2212. For example, the first telescopic column 2211 is slidably connected to the support platform 21 along its length, and the second telescopic column 2212 is fixedly connected to the support platform 21. Among them, the first telescopic column 2211, the second telescopic column 2212 and the third telescopic column 2213 can all be telescopic hydraulic cylinder structures.

[0030] Understandably, when the tunneling workpiece moves forward one step (the distance between two portal supports 1), the transport vehicle 23 is first moved forward one step, the piston rod of the first telescopic column 2211 is retracted to lift the first telescopic column 2211 off the roadway surface, the third telescopic column 2213 is operated to pull the first telescopic column 2211 towards the second telescopic column 2212 one step, the first telescopic column 2211 is raised and supports the support platform 21, the piston rod of the second telescopic column 2212 is retracted and lifted off the roadway surface, the third telescopic column 2213 is operated to push the second telescopic column 2212 forward one step, the second telescopic column 2212 is raised and supports the support platform 21, thus completing the forward movement of the transport device 2 one step.

[0031] In some embodiments, such as Figure 1 As shown, the transport device 2 also includes a support assembly 24, which includes a first support plate 241 and a fourth telescopic column 242. The fourth telescopic column 242 is located at the front end of the support platform 21, with its lower end connected to the support platform 21 and its upper end connected to the first support plate 241. The first support plate 241 is used to support the roadway roof. It can be understood that the fourth telescopic column 242 is a hydraulic cylinder, which can be raised to allow the first support plate 241 to support the roof of the roadway working face, thereby improving the reliability of roadway excavation.

[0032] Furthermore, such as Figure 1 As shown, the support assembly 24 also includes a second support plate 243 and a fifth telescopic column 244. The second support plate 243 is located at the front end of the first support plate 241 and is pivotally connected to the first support plate 241. The fifth telescopic column 244 is located at the front end of the support platform 21, with its lower end connected to the support platform 21 and its upper end connected to the second support plate 243. The fifth telescopic column 244 is used to drive the second support plate 243 to swing relative to the first support plate 241. It can be understood that when it is necessary to move the transport device 2 forward by one step, the fifth telescopic column 244 and the fourth telescopic column 242 can be retracted, thereby separating the first support plate 241 and the second support plate 243 from the roadway roof to facilitate the forward movement of the support platform 21. When the transport device 2 has finished moving and the roadway needs to be supported, the fifth telescopic column 244 and the fourth telescopic column 242 can be lifted so that the first support plate 241 and the second support plate 243 can contact the roadway roof, thereby supporting the tunneling face and improving the reliability of roadway excavation.

[0033] In some embodiments, such as Figure 2As shown, the gantry frame 1 also includes two telescopic beams 13, which are respectively located on both sides of the support beam 11 along its length. The upper end of the support column 12 is connected to the telescopic beams 13. In the working state, the telescopic beams 13 extend, and in the moving state, the telescopic beams 13 retract. It can be understood that because both ends of the gantry frame 1 are telescopic, the width of the gantry frame 1 can be reduced in the moving state to prevent interference between the gantry frame 1 and other components during transportation.

[0034] Optionally, such as Figure 2 As shown, the portal frame 1 also includes a support bottom shoe 14, which is pivotally mounted at the lower end of the support column 12. By providing the support bottom shoe 14, the roadway support device of this embodiment of the invention allows for a larger contact area between the portal frame 1 and the roadway floor, thereby improving the stability of the portal frame 1.

[0035] Optionally, the upper surface of the support platform 21 is provided with a guide rail 211, which extends along the length of the support platform 21. The lower end of the transport vehicle 23 is provided with a roller 231, which cooperates with the guide rail 211 and is movable along the length of the guide rail 211. By setting the guide rail 211 and the roller 231, the tunnel support equipment of the embodiment of the present invention can improve the accuracy of the movement of the transport vehicle 23, avoid the risk of the transport vehicle 23 detaching from the support platform 21, and improve the safety of the gantry support 1 during transportation.

[0036] In some embodiments, the roadway support equipment further includes a control system (not shown), which is electrically connected to the gantry support 1 and the transport device 2. The control system controls the gantry support 1 to switch between a working state and a moving state, and controls the forward and backward movement of the traveling assembly 22 and the transport vehicle 23. The roadway support equipment of the embodiments of the present invention, through the control system, can improve the intelligence level of roadway support equipment support and transport, and is convenient for operators to use and operate, thus possessing strong practicality.

[0037] The working principle of the tunnel support equipment according to an embodiment of the present invention is as follows:

[0038] When the tunneling workpiece approaches the portal support 1 by one step, the transport vehicle 23 is first moved forward by one step. The first telescopic column 2211 is operated to retract its piston rod, so that the first telescopic column 2211 leaves the roadway surface. The third telescopic column 2213 is operated to pull the first telescopic column 2211 towards the second telescopic column 2212 by one step. The first telescopic column 2211 is raised and supports the support platform 21. The second telescopic column 2212 is operated to retract its piston rod and leave the roadway surface. The third telescopic column 2213 is operated to push the second telescopic column 2212 forward by one step. The second telescopic column 2212 is raised and supports the support platform 21. This completes the forward movement of the transport device 2 by one step.

[0039] Operate the fourth telescopic column 242 to bring the first support plate 241 into contact with the roof, and operate the fifth telescopic column 244 to bring the second support plate 243 into close contact with the tunnel roof. Then move the gantry frame 1, operate the last gantry frame 1, operate the support column 12 to retract it, and the support beam 11 contacts the transport vehicle 23. Continue to operate the support column 12 to retract it, so that the support column 12 and the support bottom shoe 14 are lifted off the tunnel floor. At the same time, the telescopic beam 13 is retracted. Operate the transport vehicle 23 to move from the rear to a position one step in front of the foremost gantry frame 1, operate the gantry frame 1 to raise its column, so that its support beam 11 contacts the tunnel roof and reaches the initial support force. The transport vehicle 23 returns to the bottom of the last gantry frame 1 to wait for the next move, thus completing the cycle of moving the gantry frame 1.

[0040] In summary, the roadway support equipment of the embodiments of the present invention has the following technical effects:

[0041] (1) The roadway support equipment of the present invention has a self-propelled mechanism (propelled component 22) that can move forward as the tunneling face advances.

[0042] (2) The roadway support equipment of the present invention is provided with a portal frame 1 transport mechanism (transport device 2), which can transport the portal frame 1 from the tail to the head.

[0043] (3) The two ends of the portal frame 1 of the roadway support equipment of the present invention are telescopic to reduce the width of the portal frame 1 and prevent the portal frame 1 from interfering with other components during transportation.

[0044] (4) The transport equipment of the roadway support equipment of the present invention can be lifted and reversed, so as to adapt to different types of roadways and have a wide range of applications.

[0045] According to another embodiment of the present invention, the transport device is the transport device 2 of the roadway support equipment of the present invention.

[0046] According to an embodiment of the present invention, when the gantry support 1 needs to be moved, the gantry support 1 can be moved to a shifting state, allowing it to be placed on the transport vehicle 23. Since the transport vehicle 23 is movable along the length of the support platform 21, the gantry support 1 can be moved to a preset position, and then moved to the working state to support the tunnel roof. Furthermore, since the support platform 21 can travel within the tunnel via the traveling assembly 22, it can advance with the tunnel excavation face and provide protection for the tunnel and the working face. Therefore, the transport device 2 of this embodiment can move forward with the advancement of the working face, is easy to move, and provides good support.
