Specifically, the conveyer still includes rabbling mechanism 6, and rabbling mechanism 6 includes stirring rod 61 and drive structure 62, and the inner chamber of hopper 1 is stretched into to the one end of stirring rod 61, and the other end is connected with drive structure 62, and drive structure 62 can drive stirring rod 61 and rotate. The stirring mechanism 6 can stir the concrete in the hopper 1, and the influence on the construction quality due to the coagulation of the concrete in the transportation process is prevented.

Further, the driving structure 62 comprises a first bevel gear 621, a second bevel gear 622, a first pulley 623, a second pulley 624, a third pulley 625, a first universal coupling 626, a second universal coupling 627, a first rotating shaft 628, a second rotating shaft 629, a telescopic profiled shaft 6210, a connecting rod 6211, a spring 6212, a belt 6213 and a third rotating shaft 6214.

As shown in fig. 2, a first bevel gear 621 is fixed to the wheel shaft 312, and a second bevel gear 622 is engaged with the first bevel gear 621. During the movement of the transportation device, the wheel shaft 312 rotates around its central axis, and the first bevel gear 621 rotates along with the wheel shaft 312, and the second bevel gear 622 rotates along with the first bevel gear 621 because the second bevel gear 622 is engaged with the first bevel gear 621.

With continued reference to fig. 2, the first rotating shaft 628 is fixed on the traction frame 313, one end of the first rotating shaft 628 is fixed with the second bevel gear 622, the other end is connected with the first universal coupling 626, the other end of the first universal coupling 626 is connected with the telescopic special-shaped shaft 6210, and the other end of the telescopic special-shaped shaft 6210 is connected with the second universal coupling 627. In practical application, the first rotating shaft 628 rotates along with the second bevel gear 622, and the first universal coupling 626, the second universal coupling 627 and the telescopic special-shaped shaft 6210 cooperate to perform a reversing function, so that the transportation device can also perform power transmission during the steering process, and simultaneously, the damage of gear teeth caused by the collision of the gear teeth of the first bevel gear 621 and the second bevel gear 622 due to the steering of the transportation device can also be prevented.

Specifically, the other end of the second universal coupling 627 is connected to a second rotating shaft 629, the second rotating shaft 629 is fixed on the traction frame 313, and the other end of the second rotating shaft 629 is connected to the first belt pulley 623. The second shaft 629 can rotate along with the second universal joint 627 to transmit power to the first pulley 623, so as to drive the first pulley 623 to rotate along with the second shaft 629.

Further, first pulley 623, second pulley 624, and third pulley 625 are simultaneously connected by belt 6213 and are all located at an inner ring of belt 6213. The belt 6213 is capable of power transmission to rotate the second pulley 624 and the third pulley 625 simultaneously when the first pulley 623 rotates.

As shown in fig. 2, the second pulley 624 is fixed to one end of the stirring rod 61 and can rotate the stirring rod 61. In practical applications, when the transportation device moves, the wheel shaft 312 rotates, and the rotation of the stirring rod 61 is realized through power transmission among the first bevel gear 621, the second bevel gear 622, the first belt pulley 623, the second belt pulley 624, the third belt pulley 625, the first universal coupling 626, the second universal coupling 627, the first rotating shaft 628, the second rotating shaft 629, the telescopic special-shaped shaft 6210, the belt 6213 and the third rotating shaft 6214, so that when the transportation device moves, the stirring rod 61 starts to rotate, and when the transportation device stops moving, the stirring rod 61 stops rotating. Whole stirring simple structure, the stirring is convenient, just can drive stirring rod 61 at the in-process of conveyer operation through existing walking structure 31 and rotate, keeps the stirring of muddy soil in real time, does not need manual control and also need additionally not set up power components such as motor again, has saved construction cost.

Specifically, one end of the third rotating shaft 6214 is connected to the third pulley 625, the other end is hinged to one end of the connecting rod 6211, and the other end of the connecting rod 6211 is hinged to the traction frame 313. As shown in fig. 4, when the lifting mechanism 5 lifts the hopper 1, the stirring rod 61 is fixed on the hopper 1, and the stirring rod 61 is lifted along with the hopper 1, and the second pulley 624 is also lifted along with the stirring rod 61. However, the belt 6213 is of a fixed length to ensure good transmission, and therefore the link 6211 is hinged to the traction frame 313, and when the lifting mechanism 5 lifts the hopper 1, the link 6211 will rotate about the traction frame 313 to release the belt 6213 and thereby effect lifting of the hopper 1.

Further, one end of the spring 6212 is connected to the link 6211, and the other end is connected to the traction frame 313. In practical application, the spring 6212 can provide a tension force to the connecting rod 6211, so that the third belt pulley 625 can be matched with the belt 6213 in real time, thereby ensuring a good power transmission effect.

With continued reference to fig. 1, the stirring rod 61 is provided with blade groups 611 at intervals along its axial direction. The provision of the blade group 611 on the stirring rod 61 can increase the contact area between the stirring rod 61 and the concrete in the hopper 1, and thus the fluid can be stirred more sufficiently.

Further, the blade group 611 includes at least two blades 611a, and the at least two blades 611a are disposed at intervals in the circumferential direction of the stirring rod 61. As shown in fig. 1, the blades 611a are provided at intervals in the circumferential direction of the stirring rod 61 to allow the fluid to be stirred more sufficiently, and in the present application, the shape of the blades 611a is not limited.

In practical application, the two sides of the discharge port are provided with clamping grooves 8, and the clamping grooves 8 are used for clamping the baffle 12. As shown in fig. 1, the clamping grooves 8 are disposed on the left and right sides of the discharge port, the clamping grooves 8 are disposed on the inner wall of the hopper 1, the clamping grooves 8 extend from the bottom end of the hopper 1 to the top end of the hopper 1, and of course, the clamping grooves 8 may not extend to the top end of the hopper 1. Comparatively speaking, when extending draw-in groove 8 to the top of hopper 1, baffle 12 can not have the gap with hopper 1 inner wall, and is better to the fixed effect of baffle 12, and the sealed effect of baffle 12 also can be better.

Specifically, the conveyer still includes blown down tank 9, and the one end of blown down tank 9 is connected with the lower terminal surface of discharge gate. Set up blown down tank 9 and can make the farther of the concrete stream of outflow in the discharge gate to also can pour the ballast bed when the ballast bed is far away from conveyer.

Further, the conveying device further comprises a fixing column 10 and a locking buckle 11, the discharging groove 9 is hinged to the lower end face of the discharging port, the fixing column 10 is fixed along two sides of the discharging port parallel to the ground, the locking buckle 11 is hinged to the discharging groove 9 and matched with the fixing column 10, and the locking buckle 11 is locked with the fixing column 10 to enable the discharging groove 9 to be fixed. As shown in fig. 3, the fixing posts 10 are fixed on the left and right sides of the discharge port, and the locking buckles 11 are hinged on the discharge chute 9 and matched with the fixing posts 10 in position and shape. In practical application, after the transportation device reaches the construction position, the locking of the locking buckle 11 and the fixed column 10 is cancelled, and then the discharging groove 9 is rotated to be aligned with the construction position. After the construction at the construction position is finished, the discharging groove 9 is rotated to be tightly attached to the outer wall of the hopper 1, and then the locking buckle 11 and the fixing column 10 are locked, so that the discharging groove 9 is fixed on the hopper 1. Fixing the discharge chute 9 in the hopper 1 can prevent the damage of the discharge chute 9 caused by the collision between the discharge chute 9 and the inside of the tunnel due to the undersize of the space inside the tunnel.

In particular, the drive mechanism 7 comprises a tractor head. Because the conveyer transports the concrete in the tunnel, the tunnel internal conditions is comparatively abominable, and power supply is more troublesome, uses tractor aircraft nose drive conveyer motion need not consider the electric power problem, only need add diesel oil can, the material is easily obtained and can satisfy the power demand. Of course, the driving mechanism 7 may be another mechanism capable of supplying power, such as an engine.

Specifically, the embodiment of the application provides a use method of the concrete transportation device for tunnel monolithic roadbed construction, which comprises the following steps:

when the transport device transports concrete into the tunnel, the catch 412 of the locking structure 41 of the first end and the locking pin 411 lock to lock the running structure 31 of the first end of the frame 2, thereby prohibiting the running structure 31 of the first end from turning.

The driving mechanism 7 at the second end drives the travelling mechanism 3 to move to the construction position.

The baffle plate 12 is opened, and the concrete in the hopper 1 flows into a construction position from the discharge port.

And closing the baffle 12 after the construction of the construction position is finished.

The catch 412 and the locking pin 411 of the locking structure 41 at the second end are locked to lock the travelling structure 31 at the second end, and the catch 412 and the locking pin 411 of the locking structure 41 at the first end are unlocked to unlock the travelling structure 31 at the first end, so that the driving mechanism 7 at the first end drives the travelling mechanism 3 away from the construction position.

When the tunnel integral ballast bed is constructed, the concrete is transported into the tunnel through the transportation device, the buckle 412 and the locking pin 411 of the locking structure 41 at the first end of the transportation device are locked to lock the running structure 31 at the first end of the vehicle frame 2, so that the running structure 31 at the first end is prohibited from turning. The driving mechanism 7 at the second end drives the travelling mechanism 3 to drive to the construction position, then the baffle 12 is opened, and the concrete in the hopper 1 flows into the construction position from the discharge hole. Because the running structure 31 of first end is locked by first end locking structure 41 to the running structure 31 of the first end of conveyer can follow the direction of motion of the running structure 31 of second end in the work progress, and the running structure 31 of first end can not turn to by oneself, thereby the conveyer can not cause the disturbance to the ballast bed in the work progress, and then can not influence the quality of the ballast bed after the construction. And closing the baffle 12 after the construction of the construction position is finished. The catch 412 and the locking pin 411 of the locking structure 41 at the second end are locked to lock the travelling structure 31 at the second end, and the catch 412 and the locking pin 411 of the locking structure 41 at the first end are unlocked to unlock the travelling structure 31 at the first end, so that the driving mechanism 7 at the first end drives the travelling mechanism 3 away from the construction position. In the process that the transporting device drives away from the construction position, the walking structure 31 at the second end is locked by the locking structure 41 at the second end, so that the walking structure 31 at the second end of the transporting device can move along the movement direction of the walking structure 31 at the first end in the construction process, the walking structure 31 at the second end can not turn to by itself, the transporting device can not cause disturbance to the track bed in the construction process, and the quality of the track bed after construction can not be influenced.
