Description

Technical Field

[0001] The present application relates to the field of tunnel boring machine technology, and in particular to a tunnel boring machine loading and unloading structure and a tunnel boring machine. Background Art

[0002] Although the existing excavator shovel and the first conveyor are partially linked to each other, there are still large openings between the shovel chute transport upper panel and the first conveyor chute transport upper panel, and between the shovel chute transport lower panel and the first conveyor chute transport lower panel.

[0003] The shovel section and the first conveyor are important components of the loading structure of the tunnel boring machine. The chute therein is smoothly connected, which can ensure the smooth passage of the upper and lower panel transport chains during horizontal loading during operation. However, when the shovel section rotates, the angle between the shovel section and the chute of the first conveyor changes, and the smooth connection between the rotated shovel chute and the chute of the first conveyor changes, which will cause the chain to run unsteadily, easily get stuck or jump, and cause serious friction and wear, thereby increasing the machine maintenance cost of the tunnel boring machine user and affecting work efficiency. Utility Model Content

[0004] In view of this, the present application provides a tunnel boring machine loading structure and a tunnel boring machine, which can ensure a smooth connection between the shovel chute and the first conveyor chute even if the angle changes, thereby avoiding chain jamming and wear, significantly reducing maintenance, and improving work efficiency.

The main body part can drive the shovel plate part and the first conveyor part to move. The shovel plate part and the first conveyor part are staggered with each other so that the connection position of the two for transporting soil is relatively close. Moreover, by staggering the bent plates with each other, after the two rotate at a relative angle, due to the characteristics of the curvature of the bent plates, the shovel plate part and the first conveyor part always maintain a relatively close connection, so that when the angle between the shovel plate part and the first conveyor chute changes, the rotated shovel plate chute and the first conveyor chute are always smoothly connected, thereby improving the stability of the chain operation, preventing chain jamming, chain jumping, and severe friction and wear, reducing the machine maintenance cost of the tunnel boring machine user, and improving work efficiency.

[0009] Preferably, the curved plate of the shovel plate portion includes a first upper curved plate, the first upper curved plate has an arc, the curved plate of the first conveyor portion includes a second upper curved portion, the second upper curved plate also has an arc, and the first upper curved plate and the second upper curved plate are staggered and matched;

[0010] Preferably, the first upper curved plate and the second upper curved plate can together form an arc with R as a radius.

[0011] Preferably, the shovel plate portion is provided with a first upper pressing plate on the bent plate, and the first conveyor portion is provided with a second upper pressing plate on the bent plate, and a gap for accommodating a scraper plate is provided between the first upper pressing plate and the second upper pressing plate.

[0014] Preferably, the lower side of the lower panel of the shovel chute is not blocked, so as to facilitate the removal of excess materials.

[0015] The tunnel boring machine provided in this application adopts the following technical solution:

[0016] A roadheader, characterized in that it comprises the roadheader loading structure, cutting mechanism and traveling mechanism as described above, wherein the cutting mechanism is connected to the roadheader loading mechanism, and the traveling mechanism is connected to the roadheader loading mechanism.

[0017] In summary, the present application includes at least one of the following beneficial technical effects:

[0018] 1. The shovel plate part is responsible for shoveling soil and transporting soil and debris through the first conveyor part. The main body part can drive the shovel plate part and the first conveyor part to move. The shovel plate part and the first conveyor part are staggered with each other so that the connection position of the two for transporting soil is relatively close. The bent plates are staggered with each other so that after the relative angle between the two is rotated, the shovel plate part and the first conveyor part always maintain a relatively close connection due to the characteristics of the curvature of the bent plates. As a result, when the angle between the shovel plate part and the first conveyor chute changes, the rotated shovel plate chute and the first conveyor chute are always smoothly connected, thereby improving the stability of the chain operation, preventing chain jamming, chain jumping, and severe friction and wear, reducing the machine maintenance cost of the tunnel boring machine user and improving work efficiency.

The shovel plate portion 9 is connected to the main body portion 15, the first conveyor portion 18 is connected to the main body portion 15, and a partial gap between the shovel plate portion 9 and the first conveyor portion 18 is sealed.

[0028] A first pin shaft 4 is provided at one end of the main body 15, and the first pin shaft 4 is connected to one end of the shovel plate part 9, so that the main body 15 and the shovel plate part 9 are rotationally connected through the first pin shaft 4, and an oil cylinder 11 is provided at the other end of the shovel plate part 9, and the other end of the oil cylinder 11 is connected to the main body 15, so that the oil cylinder 11 is extended and retracted, driving the shovel plate part 9 to rotate around the first pin shaft 4 on the main body 15.

The second upper curved plate 3 also has an arc, and the second upper curved plate 3 is provided at one end near the shovel plate portion 9. The bent plates 3 are symmetrically arranged on both sides of the ends of the upper panel of the first conveyor chute, so that the second upper bent plate 3 of the first conveyor chute and the first upper bent plate 7 of the shovel plate part 9 are staggered and matched, so that the shovel plate chute is smoothly connected to the upper side of the first conveyor chute, and because the first upper bent plate 7 and the second upper bent plate 3 have an arc, when the shovel plate chute and the first conveyor chute rotate at a relative angle, the shovel plate chute and the first conveyor chute always maintain a gap-sealed state due to the arc-shaped first upper bent plate 7 and the second upper bent plate 3, thereby improving the smoothness of the chain operation.

[0031] Furthermore, in this embodiment, the first upper curved plate 7 and the second upper curved plate 3 can cross each other to form an arc with a radius of R, so as to further improve the stability of the junction between the shovel chute and the first conveyor chute when the shovel chute and the first conveyor chute rotate at a relative angle.

[0036] Furthermore, in this embodiment, the lower side of the lower panel of the shovel chute is not blocked, and excess material can be discharged to avoid the chain getting stuck at the interface.

[0037] The structure of the present invention can make the upper and lower working surfaces of the chain seamlessly and smoothly connected at any position of the working angle of the shovel plate, thereby ensuring the smooth and stable connection of the two chain transmission transport surfaces, effectively avoiding the disadvantages such as chain jamming, reducing friction, improving work efficiency, and extending the service life of the machine.
