Description

Technical Field

[0001] This invention belongs to the field of engineering equipment, and in particular relates to a support machine for subway tunnel construction. Background Technology

[0002] A subway is a high-speed, high-capacity, electrically powered rail transit system built in cities. Trains run on fully enclosed tracks, with lines in central urban areas primarily located in underground tunnels.

[0003] Subways are a major mode of public transportation in modern metropolises, and with development, subway lines are constantly increasing and extending. The construction of subways is basically the same as that of tunnels. Specialized machinery is used to excavate a regular tunnel underground. Support devices are needed during the subway excavation process to support the subway tunnel and prevent the risk of collapse. The support machine is the mechanical equipment that installs the steel frame for support into the subway tunnel.

[0004] As is well known, the support structure of a subway tunnel is assembled from multiple identical arc-shaped steel frames. Currently, when carrying out support construction, the arc-shaped steel frames first need to be transported into the tunnel, and then installed on the support machine. After the support machine lifts the arc-shaped steel frames, manual assembly is assisted. Therefore, this process requires a variety of construction equipment, such as transport vehicles and support machines, which makes the site space relatively crowded and inconvenient for the support construction. Summary of the Invention

[0005] The purpose of this invention is to provide a support machine for subway tunnel construction, which aims to solve the problems mentioned in the background art.

[0006] The present invention is implemented as follows: a subway tunneling support machine includes a traction vehicle, a cargo platform mounted on the traction vehicle, and further includes:

[0007] A conveying assembly is set on a loading platform and is arranged along the length of the loading platform. Multiple supporting steel frames are arranged on the conveying assembly along its own length.

[0008] The lifting assembly is located on one side of the cargo platform and at the rear of the traction vehicle. The lifting assembly is arranged vertically. The output end of the lifting assembly consists of two horizontally spaced forks facing the conveying assembly. The conveying assembly is used to drive the support steel frame to move laterally, so that the support steel frame falls onto the two horizontal forks. The lifting assembly is used to drive the support steel frame on the horizontal forks to move vertically.

[0009] The lifting assembly is mounted on the loading platform and located on the side away from the lifting component. The lifting assembly includes a base fixedly connected to the loading platform, a telescopic robotic arm mounted on the base, and a gripping component mounted on the other end of the telescopic robotic arm.

[0010] Preferably, the conveying assembly includes two spaced support plates fixedly connected to the loading platform, with the support plates arranged along the length of the loading platform. Multiple mounting rollers are rotatably arranged between the two support plates, and a transmission chain is fitted on the mounting rollers. Multiple push plates are fixedly arranged at intervals on the transmission chain. A support steel frame is located on top of the support plates and between the push plates. The two crossbars in the lifting assembly are both located between the support plates.

[0011] Preferably, an extension plate is fixedly connected to the end of each of the two support plates near the lifting assembly, and a positioning block is fixedly connected to the top of the extension plate near the lifting assembly. The end of the cross fork near the conveying assembly is located between the extension plates.

[0012] Preferably, the top of the support plate is rotatably provided with a plurality of support rollers, which are spaced apart along the length of the support plate and are in contact with the support steel frame.

[0013] Preferably, both sides of the conveying component on the loading platform are rotatably connected to a top plate, the top plate is in contact with both ends of the supporting steel frame, the top plate is set along the length of the loading platform, and a telescopic structure is set on the outside of the top plate, the telescopic structure is used to drive the top plate to rotate.

[0014] Preferably, the push plate is composed of a first plate and a second plate. The first plate is fixedly connected to the transmission chain, and the second plate is located on top of the first plate. A limit rod is fixedly connected to one side of the top of the first plate, and an adjusting screw is rotatably connected to the other side. The second plate has sleeve holes and threaded holes that cooperate with the limit rod and the adjusting screw, respectively. A handle for driving the adjusting screw to rotate is provided on the side of the second plate away from the first plate.

[0015] Preferably, the base includes a chassis fixedly mounted on a loading platform, an operating station rotatably mounted on the chassis, and a telescopic robotic arm rotatably mounted on the operating station.

[0016] Preferably, the gripping assembly includes a mounting frame rotatably connected to one end of the telescopic robotic arm, an open gripper fixedly connected to the mounting frame, and a telescopic component for driving the mounting frame to rotate is provided between the mounting frame and the telescopic robotic arm.

[0017] Preferably, the surface of the cross fork is provided with an anti-slip structure.

[0018] The beneficial effects of the subway tunnel construction support machine provided by the present invention are: ① When the present invention is put into use, the conveying component can play the role of supporting the steel frame.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0027] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0028] like Figure 1 The diagram shown illustrates the structure of a subway tunnel construction support machine according to an embodiment of the present invention, comprising:

[0029] Towing vehicle 1, with a cargo platform 2 mounted on it, also includes:

[0030] The conveying component 3 is set on the loading platform 2 and is arranged along the length direction of the loading platform 2. Multiple supporting steel frames 4 are arranged on the conveying component 3 along its own length direction.

[0031] The lifting component 5 is located on one side of the loading platform 2 and at the rear of the traction vehicle 1. The lifting component 5 is arranged vertically. The output end of the lifting component 5 consists of two horizontally spaced forks 501 facing the conveying component 3. The conveying component 3 is used to drive the support steel frame 4 to move laterally, so that the support steel frame 4 falls onto the two horizontal forks 501. The lifting component 5 is used to drive the support steel frame 4 on the horizontal forks 501 to move vertically.

[0032] The lifting assembly 6 is mounted on the loading platform 2 and is located on the side away from the lifting assembly 5. The lifting assembly 6 includes a base 601 fixedly connected to the loading platform 2, a telescopic robotic arm 602 mounted on the base 601, and a gripping assembly 603 mounted on the other end of the telescopic robotic arm 602.

[0033] In one embodiment of the present invention, when the present invention is put into use, the conveying component 3 can serve to support the steel frame 4. Therefore, the support machine can transport the steel frame 4. The support machine integrates a lifting component 6 for lifting the steel frame 4 to a certain height, without losing its original function. The support machine can transport the steel frame 4 into the subway tunnel and can also lift the steel frame 4. Through the cooperation of the conveying component 3 and the lifting component 5, the support machine can lift and move a single steel frame 4 to a certain height, thereby facilitating the gripping component 603 for fixing. Unlike conventional support machines, which require a suspension device to assist in the installation of the steel frame 4, the support machine can achieve this operation itself, making it more convenient to use.

[0034] In one embodiment of the present invention, the base 601 includes a chassis 6011 fixedly mounted on the loading platform 2. An operating station 6012 is rotatably mounted on the chassis 6011, and a telescopic robotic arm 602 is rotatably mounted on the operating station 6012. The operating station 6012 can control its rotation on the chassis 6011. Therefore, the lifting assembly 6 can not only vertically lift the supporting steel frame 4, but also laterally lift the supporting steel frame 4, making operation more flexible. Figure 4 As shown, the gripping assembly 603 includes a mounting frame 6031 rotatably connected to one end of the telescopic robotic arm 602. An open gripper 6032 is fixedly connected to the mounting frame 6031. A telescopic component 6033 is provided between the mounting frame 6031 and the telescopic robotic arm 602 to drive the mounting frame 6031 to rotate. The telescopic component 6033 can be hydraulically telescopic or pneumatically telescopic. When the supporting steel frame 4 enters the open gripper 6032, the posture of the supporting steel frame 4 can be adjusted via the telescopic component 6033 to facilitate subsequent installation. Figure 2 As shown, the lifting component 5 includes two support rails 502 fixedly connected to one side of the loading platform 2. A crossbeam 503 is slidably arranged between the support rails 502. A crossbow 501 is fixedly connected to the crossbeam 503. A first motor 504 is arranged between the support rails 502. A screw 505 is fixedly connected to the output end of the first motor 504. The crossbeam 503 is connected to the screw 505. The first motor 504 is used to drive the screw 505 to rotate, so that the crossbeam 503 can be raised or lowered. The surface of the crossbow 501 is provided with an anti-slip structure. The anti-slip structure can be a rubber sleeve wrapped around the crossbow 501, or a serrated structure can be provided on the surface of the crossbow 501.

[0035] like Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, the conveying assembly 3 includes two spaced support plates 301 fixedly connected to the loading platform 2, and the support plates 301 are arranged along the length direction of the loading platform 2. A plurality of mounting rollers 302 are rotatably arranged between the two support plates 301. A transmission chain 303 is fitted on the mounting rollers 302. A plurality of push plates 304 are fixedly arranged at intervals on the transmission chain 303. The support steel frame 4 is located on the top of the support plates 301 and between the push plates 304. The two cross forks 501 in the lifting assembly 5 are both located between the support plates 301.

[0036] In one embodiment, a second motor 305 is fixedly connected to the outer side of the support plate 301 on the loading platform 2. The second motor 305 drives the mounting roller 302 to rotate via a transmission component 306. The transmission component 306 can be a chain drive or a gear drive. When the mounting roller 302 rotates, the push plate 304 can push the support steel frame 4 to move laterally. Extension plates 7 are fixedly connected to the ends of the support plates 301 near the lifting component 5 on both sides. A positioning block 8 is fixedly connected to the top of the extension plate 7 near the lifting component 5. The end of the cross fork 501 near the conveying component 3 is located between the extension plates 7. This structure allows the support steel frame 4 to move laterally to directly above the cross fork 501, facilitating its lifting by the cross fork 501. Figure 3 As shown, the top of the support plate 301 is rotatably provided with multiple support rollers 9. The support rollers 9 are spaced apart along the length of the support plate 301. The support rollers 9 are in contact with the support steel frame 4. Generally speaking, the support steel frame 4 is relatively heavy. After the support rollers 9 are provided, the push plate 304 pushes the support steel frame 4 to move laterally more smoothly.

[0037] like Figure 3 As shown, in a preferred embodiment of the present invention, the top plate 10 is rotatably connected to both sides of the conveying component 3 on the loading platform 2. The top plate 10 is in contact with both ends of the supporting steel frame 4. The top plate 10 is arranged along the length direction of the loading platform 2. A telescopic structure 11 is provided on the outer side of the top plate 10. The telescopic structure 11 is used to drive the top plate 10 to rotate.

[0038] In one embodiment, when loading the support steel frame 4, it is placed directly on the conveying assembly 3. When the traction vehicle 1 is moving, the support steel frame 4 cannot be stabilized by the push plate 304 alone and may sway. However, the top plate 10 is deflected by the telescopic structure 11, and the top plate 10 can lift the support steel frame 4 from both sides, thereby separating the support steel frame 4 from the conveying assembly 3 and fixing the support steel frame 4 for convenient transportation. The telescopic structure 11 can be in the form of a cylinder or an electric telescopic rod.

[0039] like Figure 5 As shown, in a preferred embodiment of the present invention, the push plate 304 is composed of a first plate 12 and a second plate 13. The first plate 12 is fixedly connected to the transmission chain 303, and the second plate 13 is located on top of the first plate 12. A limit rod 14 is fixedly connected to one side of the top of the first plate 12, and an adjusting screw 15 is rotatably connected to the other side. The second plate 13 has sleeve holes and threaded holes that respectively cooperate with the limit rod 14 and the adjusting screw 15. A handle 16 for driving the adjusting screw 15 to rotate is provided on the side of the second plate 13 away from the first plate 12.

[0040] In one embodiment, the supporting steel frames 4 used in different tunnels are generally different, meaning that the radii of curvature of the supporting steel frames 4 are different. When the radius of curvature of the supporting steel frame 4 is large, the push plate 304 can definitely contact the supporting steel frame 4, thereby pushing it to move. However, when the radius of curvature of the supporting steel frame 4 is small, the push plate 304 may not be able to contact the supporting steel frame 4 because the top of the supporting steel frame 4 is more arched. Therefore, the above structure is set up so that the distance between the first plate 12 and the second plate 13 can be adjusted by the handle 16, thereby adjusting the height of the push plate 304, so that the conveying assembly 3 can stably push different supporting steel frames 4 to move laterally.

[0041] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
