As shown in FIG. 1, FIG. 4 and FIG. 5, the suspension moving device 9 of the tunneling machine according to an embodiment of the present invention comprises rails 1 and a lifting mechanism 3.

The lifting mechanism 3 is movably mounted on the rails 1. The lifting mechanism 3 comprises a lower frame 302 for horizontal movement, a rotary frame 310, a pivot bearing 308 and a drive mechanism 305. A pivot bearing 308 is connected to a lower frame 302 for horizontal movement and pivoting frame 310. The pivoting frame 310 by means of a slewing bearing 308 is made to rotate relative to the lower frame 302 for horizontal movement. The drive mechanism 305 due to the engagement is connected to the slewing bearing 308 and is designed to drive the slewing bearing 308 to rotate the slewing frame 310 relative to the lower frame 302 for horizontal movement.

The engagement used in the above suspension device 9 of the tunneling machine can provide features such as simplicity and compactness of the structure between the lower horizontal moving frame 302 and the swing frame 310, which can reduce the failure rate of the suspension moving device 9 and make maintenance convenient, as well as increases the efficiency of the tunneling machine.

In particular, the rails 1 can be made by connecting in series by means of clamping plates, bolts and the like. several grooved rails. The rails 1 can be installed by means of bolts inside the main beam and the connecting bridge of the tunneling machine. The rails 1 can provide an open path for the passage of the suspension moving device 9 and withstand the loads that arise during the movement of the suspended segment 12 of the bottom of the tunnel.

In some embodiments, the slewing bearing 308 comprises an outer gear ring 308a. The suspension moving device 9 comprises a rotary gear rack 309. The rotary gear rack 309 is engaged with the outer gear ring 308a. The drive mechanism is designed to bring the rotary gear rack 309 into reciprocating motion to actuate the slewing bearing 308 to rotate the rotary frame 310 relative to the lower frame 302 for horizontal movement.

In particular, the pivot frame 310 can be firmly connected to the outer ring of the pivot bearing 308, and the lower frame 302 for horizontal movement can be firmly connected to the inner ring of the pivot bearing 308. The outer gear ring 308a is mounted on the outer ring of the pivot bearing bearing 308 or performed on the outer ring of a slewing bearing 308.

As seen in FIG. 2, in some embodiments, the rails 1 comprise a first horizontal section 101, a second horizontal section 105, and a transition connecting section 102a. The second horizontal section 105 and the first horizontal section 101 are made at different heights. The transitional connecting section 102a connects the first horizontal section 101 with the second horizontal section 105.

Thus, under the first horizontal section 101, the means of transporting the segments of the bottom of the tunnel can stop, and under the second horizontal section 105 of the tunneling machine, a conveyor belt can be provided, and after lifting the segment 12 of the bottom of the tunnel from the means of transportation of the segments of the bottom of the tunnel, the lifting mechanism 3 reaches the second horizontal section 105 above the conveyor belt of the tunneling machine, sequentially passing the first horizontal section 101 and the transition connecting section 102a; Thus, the segments 12 of the bottom of the tunnel can be moved from the means of transportation of the segments of the bottom of the tunnel to the conveyor belt of the tunneling machine using only one suspension moving device 9, which increases the efficiency of tunneling.

In an embodiment of the present invention, the distance between the first horizontal section 101 and the ground is greater than the distance between the second horizontal section 105 and the ground. Thus, the means of transporting the segments of the bottom of the tunnel can be placed under the first horizontal section 101.

In some embodiments, the transition connecting section 102a between the first horizontal section 101 and the second horizontal section 105 comprises successively extending outwardly curved section 102, an inclined section 103 and inwardly curved section 104.

The outwardly curved section 102 is connected to the first horizontal section 101, the inclined section 103 is inclined relative to the first horizontal section 101 and connects the outwardly curved section 102 to the inwardly curved section 104, and the inwardly curved section 104 is connected to the second horizontal section 105.

Thus, it is possible to provide a smooth tilt between the first horizontal section 101 and the second horizontal section 105, which facilitates the smooth movement of the lifting mechanism 3 from the first horizontal section 101 to the transition connecting section 102a and its smooth movement from the transition connecting section 102a to the second horizontal section 105.

In some embodiments, an outwardly curved section 102 connects to each other a first horizontal section 101 and an inclined section 103, and an inwardly curved section 104 connects to each other a second horizontal section 105 and an inclined section 103.

Thus, the lifting mechanism 3 can also smoothly move from the first horizontal section 101 to the transitional connecting section 102a and smoothly move from the transitional connecting section 102a to the second horizontal section 105.

As shown in FIG. 4 and FIG. 5, in some embodiments, the drive mechanism 305 is a hydraulic cylinder, wherein the hydraulic cylinder body is attached to the lower frame 302 for horizontal movement, and the piston rod of the hydraulic cylinder is firmly connected to the rotary gear rack 309 by means of a slide bar 306.

Thus, by making reciprocating movements, the piston rod of the hydraulic cylinder can cause the rotary gear rack 309 to reciprocate, and thus rotate the rotary frame 310 relative to the lower frame 302 for horizontal movement. In addition, the hydraulic cylinder can make the design of the suspension moving device 9 simpler and easier to control, which can reduce the cost of the suspension moving device 9 and increase the reliability of the suspension moving device 9.

As shown in FIG. 2, when the piston rod of the hydraulic cylinder is pulled out of the cylinder body, the slide bar 306 together with the rotary gear rack 309 moves to the left and thus drives the outer gear ring 308a to rotate the rotary frame 310 relative to the lower frame 302 for horizontal counterclockwise movement ( if you look from top to bottom). When the piston rod of the hydraulic cylinder is pulled into the cylinder body, the extension bar 306 moves in the same direction with the rotary gear rack 309, and thus drives the outer gear ring 308a to rotate the rotary frame 310 relative to the lower frame 302 for horizontal clockwise movement ( if you look from top to bottom).

As shown in FIG. 1 and FIG. 3-5, in some embodiments, the lifting mechanism 3 comprises a lifting chassis 2 and an upper frame 301 for horizontal movement mounted on the lifting chassis 2. A lifting chassis 2 includes a lifting chassis 201 and sprockets 202 mounted on the lifting chassis 201, while the articulated wheels 202 with the possibility of rolling mounted on the rails 1.

The upper frame 301 for horizontal movement can make movements perpendicular to the longitudinal direction of the rails 1, and the upper frame 301 for horizontal movement is connected to the lower frame 302 for horizontal movement.

Thus, when moving along the rails 1, the lifting chassis 2 can move along the rails 1 together with the lifting mechanism 3 and, thus, move the suspended segment 12 of the bottom of the tunnel. Swivel wheels 202 can reduce friction during movement of the lifting chassis 2.

In addition, when moving, the upper frame 301 for horizontal movement can move the segment 12 of the tunnel bottom raised by the lifting mechanism 3 perpendicular to the longitudinal direction of the rails 1. As shown in FIG. 1, the longitudinal direction of the rails 1 is a forward or backward direction, and the direction perpendicular to the rails 1 is a left or right direction. In other words, the upper frame 301 for horizontal movement can move left or right, so that when the suspended segment 12 of the bottom of the tunnel moves, the suspension moving device 9 can move the segment 12 of the bottom of the tunnel left or right.

In particular, as seen in FIG. 3 and FIG. 4, the upper frame 301 for horizontal movement can be moved perpendicular to the longitudinal direction of the rails 1 by means of a hydraulic cylinder 303. The housing of the hydraulic cylinder 303 can be mounted on the upper frame 301 for horizontal movement, and the extension end of the piston rod of the hydraulic cylinder 303 is connected to the mounting member 203 of the lifting chassis frames 201.

As seen in FIG. 5, in some embodiments, the upper frame 301 for horizontal movement can rotate relative to the lower frame 302 for horizontal movement, while the lifting mechanism 3 includes a connecting plate 307, and after rotating the upper frame 301 for horizontal movement relative to the lower frame 302 for horizontal movement, the connecting plate 307 firmly connects the upper frame 301 for horizontal movement with the lower frame 302 for horizontal movement.

Thus, after rotation, the upper frame 301 for horizontal movement can adapt to the inclined rails 1, so that the lower frame 302 for horizontal movement can remain in a horizontal position, and therefore, it is ensured that the suspended segment 12 of the bottom of the tunnel moved by the suspended moving device 9, maintains an appropriate constant position in space, and accidents caused by the occurrence of harmonic oscillations of segments 12 of the bottom of the tunnel are prevented.

As shown in FIG. 4 and FIG. 5, the upper frame 301 for horizontal movement can be rotated relative to the lower frame 302 for horizontal movement around the connecting pins 304. After rotating the upper frame 301 for horizontal movement at a certain angle, the connecting plate 307 connects the upper frame 301 for horizontal movement with the lower frame 302 for horizontal movement and fixes it. Thus, the inclination of the upper frame 301 for horizontal movement relative to the lower frame 302 for horizontal movement is provided in order to adapt it to the inclined rails 1.

For example, when moving in the direction of the rail connecting section 102a of the rails 1, the lifting mechanism 3 can move the upper frame 301 for horizontal movement into an inclined position, so that the upper horizontal frame 301 and the transition connecting section 102a remain generally parallel to each other, and the lower frame 302 for horizontal movement may remain in a horizontal position.

As shown in FIG. 1, FIG. 6 and FIG. 7, in some embodiments, the suspension moving device 9 of the tunneling machine comprises lifting modules 4 and hanging grips 406, the lifting modules 4 being mounted on a swing frame 310. The lifting modules 4 comprise a sling 404, a rotating wheel 403, and a drive unit 402. Drive unit 402 represents, for example, a hydraulic motor, a gear motor, and the like. Sling 404 is, for example, a chain.

The suspension gripper 406 is connected to the sling 404, while the suspension gripper 406 is, for example, a suspension hook, bolt, etc. The sling 404 is wound on a rotating wheel 403. The drive unit 402 is connected to the rotating wheel 403 and is designed to drive the rotating wheel 403 in rotation.

Thus, the rotation of the rotary wheel 403 can be controlled by the retraction and extension of the sling 404, and thus, the distance between the specified suspension gripper 406 and the indicated rotary frame 310 can be adjusted to raise and lower the suspended segment 12 of the tunnel bottom during movement.

In some embodiments, the number of lift modules 4 is three, with three lift modules 4 evenly distributed in a circle.

Thus, three lifting modules 4 can give the segment 12 of the bottom of the tunnel greater stability when raising and lowering and to balance the forces in the lifting mechanism 3.

In some embodiments, the lifting module 4 comprises a drive box 401 and a chain box 405 mounted on the drive box 401; a rotating wheel 403 is installed in the drive box 401; a drive unit 402 is mounted outside the drive box 401; one end of the sling 404 is firmly connected to the suspension gripper 406, and the other end of the sling 404 is fixed in the chain box 405, while the chain box 405 is designed to guide the retraction and extension of the sling 404.

Thus, the box 405 for the chain can reduce the braking time of the sling 404 that occurs when it is retracted and pulled, which makes the operation of the suspension moving device 9 more stable and the failure rate low.

As shown in FIG. 1, in some embodiments, the suspension moving device 9 of the tunneling machine comprises a travel drive unit 5 and a first connecting rod 7. A travel drive unit 5 is movably mounted on the rails 1. A first connecting rod 7 connects the lifting mechanism 3 and the travel drive unit 5. The chassis the drive unit 5 through the first connecting rod 7 causes the lifting mechanism 3 to move along the rails 1.

Thus, a modular structure can be made between the driving drive unit 5 and the lifting mechanism 3, while the structure is simple and the arrangement is compact, which helps to reduce the size of the suspension moving device 9 so that it fits the different needs arising from the construction of tunnels.

As seen in FIG. 2, FIG. 8 and FIG. 9, in some embodiments, the travel drive assembly 5 comprises a travel drive frame 501 and a travel drive mechanism. It should be noted that the rails 1 in FIG. 8 are indicated by the dotted line. The driving drive frame 501 is movably mounted on the rails 1. The driving drive mechanism connects the rails 1 to the driving drive frame 501 and is designed to provide movement of the driving drive frame 501 along the rails 1.

In some embodiments, the running gear includes running gear racks 106, running gears 503, and running gear motor 502. The running gear racks 106 are attached to the bottom of the rails 1. The running gear rails 106 extend in the longitudinal direction of the rails 1, and the running gears 503 stay with toothed racks 106 meshed. The driving drive motor 502 is mounted on the running drive frame 501. The running gears 503 are connected to the output shaft of the driving drive motor 502.

Thus, in the interaction of the running gears 503 with the running gear racks 106, the driving drive motor 502 can rotate the driving drive unit 5 and the lifting mechanism 3 along the rails 1 by rotating the driving gears 53, provides more stable movement of the lifting mechanism 3 and the correspondence suspension moving device 9 of the tunneling machine the requirements for construction work with a large inclination of the tunneling machine, and can also prevent slipping on Removable mechanism 3.

In particular, running wheels 506 are mounted on the running drive frame 501, while the running wheels 506 are mounted on the rails 1 with the possibility of rolling in order to reduce the friction force when moving the driving drive unit 5 along the rails 1.

In some embodiments, the shape of the gear racks 106 corresponds to the shape of the rails 1. For example, the gear racks 106 comprise serially connected a first straight gear section 106a, an outwardly curved gear section 106b, an inclined gear section 106c, an inwardly curved gear section 106d, and a second straight gear rack section 106e. The first straight gear section 106a, the outwardly curved gear section 106b, the inclined gear section 106c, the inward curved section 106d and the second straight gear section 106e are properly connected to the first horizontal section 101, the outward curved section 102, the inclined section 103 bent inwardly by section 104 and second horizontal section 105 of rails 1, respectively.

In some embodiments, the running gears 503 are coupled to the output shaft of the driving drive motor 502 via an intermediate gear 504.

As seen in FIG. 9, in some embodiments, the number of rails 1 is two, with two rails 1 parallel to each other and a gear rack 106 provided on each rail 1. The number of running gears 503 is two, each of the two running gears 503 being meshed with the corresponding toothed rack 106. The toothed drive unit 5 comprises a drive shaft 505 connected to two toothed wheels 503, while the toothed drive motor 502 is designed to drive ix one of the running gears 503.

Thus, the drive shaft 505 can drive two running gears 503 in synchronous rotation by only one engine and, thus, move the lifting mechanism 3 along the rails 1, which can reduce the number of engines and reduce the cost of the suspension moving device 9.

As shown in FIG. 1 and FIG. 10, in some embodiments, the suspension moving device 9 of the tunneling machine comprises a hydraulic power unit 6 and a second connecting rod 8, wherein the hydraulic power unit 6 comprises a mounting frame 601 and a hydraulic power unit 602.

The mounting frame 601 is movably mounted on the rails 1. The second connecting rod 8 connects the mounting frame 601 to the driving drive unit 5. The hydraulic power unit 602 is mounted on the mounting frame 601. The hydraulic power unit 602 is designed to provide the suspension moving device 9 of the tunneling machine with hydraulic power .

Of course, the hydraulic power unit 602 includes a hydraulic pump, a hydraulic valve, a hydraulic pipe and other elements, which, thus, together can constitute the hydraulic oil channel of the suspension moving device 9, which makes it convenient to maintain the suspended moving device 9.

The tunneling machine according to an embodiment of the present invention comprises an overhead moving device 9 of the tunneling machine according to any of the above embodiments.

In a tunneling machine according to an embodiment of the present invention, the interaction of the external gear ring 308a with the rotary gear rack 309 can provide features such as simplicity and compactness of the structure between the lower horizontal frame 302 and the support of the rotary frame 310, and can also reduce the failure rate of the suspension moving device 9, make maintenance convenient and improve the efficiency of the tunneling machine.
