TECHNICAL FIELD

[0002] A boring machine is a machine used for tunneling in a straight line. As the field of boring machines becomes more diverse, boring machines need to meet different tunnel line requirements, and need to be used for boring in large-angle uphill and downhill tunnel lines during construction.
[0003] The muck receiving bucket of the conventional boring machine is usually provided with a muck receiving plate at the muck inlet. The muck chute has a fixed included angle with the vertical direction. During the falling of the muck, the muck contacts the muck chute and enters the muck receiving bucket under the action of the muck chute, preventing the muck from directly falling and damaging the belt conveyor.
[0004] However, when encountering a large-angle uphill, the angle of the muck chute is fixed, and the muck may directly fall and damage the belt conveyor during the falling of the muck. When encountering a large-angle downhill, due to the fixed angle of the muck chute, the friction between the muck and the muck chute is too large, and the muck cannot be normally mucked.

[0033] The specific embodiments of the application have been shown by way of example in the above figures, and will be described in more detail hereafter. These figures and this written description are not intended to limit the scope of the inventive concept in any way, but rather to illustrate the inventive concept to one of ordinary skill in the art by reference to specific embodiments. DETAILED DESCRIPTION
[0034] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The description of the exemplary embodiments is intended to apply to any embodiment of the application, unless specified otherwise. It should be understood that every embodiment need not necessarily include all of the features shown in the drawings or all of the components described in the text, but is intended to include only those features, components or steps that are specifically set forth or otherwise deliberately excluded. Moreover, it should be understood that the description of the exemplary embodiments is intended merely to be illustrative of the application and should not be taken in a restrictive sense.
[0035] Firstly, the terms involved in the present application are explained:
[0036] Boring machine is a machine used for tunneling in flat ground. There are many types of boring machines: according to the operation object, there are ordinary machines and tunnel boring machines (TBM); according to the operation mode, there are open type boring machines and shield type boring machines.
[0037] As described in the background art, the boring machine is a comprehensive device that uses machinery to break rocks, remove spoil and support for continuous operation. During the spoil removal process, the broken spoil is transported out by the belt conveyor. The traditional spoil receiving hopper is usually provided with a spoil receiving plate at the spoil inlet. The spoil receiving plate has a fixed angle with the vertical direction. During the falling process of the spoil, the spoil contacts the spoil receiving plate and enters the spoil receiving hopper under the action of the spoil receiving plate, preventing the spoil from falling directly and damaging the belt conveyor.
[0038] Because the angle of the spoil receiving plate is fixed, when encountering a large-angle uphill tunnel line, the spoil falling process is prone to the problem of spoil falling directly and damaging the belt conveyor. When encountering a large-angle downhill tunnel line, the problem of excessive friction between the spoil and the spoil receiving plate occurs, which cannot normally remove the spoil.
[0039] In view of the above technical problems, the present application provides a boring machine spoil receiving hopper structure. By adjusting the angle between the first spoil receiving plate 200 and the spoil hopper body 100 through the first adjusting assembly 300, the problem of spoil falling directly and damaging the belt conveyor when encountering a large-angle uphill tunnel line is solved. At the same time, the problem of excessive friction between the spoil and the spoil receiving plate when encountering a large-angle downhill tunnel line is also solved.
[0040] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific examples. The following specific examples can be combined with each other, and the same or similar concepts or processes can not be described again in some examples. The embodiments of the present application will be described below with reference to the accompanying drawings.
[0041] As shown in Figure 1 and Figure 2 , the present embodiment provides a mucking bucket structure of a tunneling machine, comprising: a mucking bucket body 100, a first mucking plate 200 and a first adjusting assembly 300, wherein the mucking bucket body 100 has a mucking channel inside the mucking bucket body 100, the mucking channel passes through the mucking bucket body 100; the first mucking plate 200 is arranged at the entrance of the mucking channel; the first mucking plate 200 is adapted to be rotatably connected with the mucking bucket body 100; the first mucking plate 200 is adapted to change the falling path of the mucking stones; the first adjusting assembly 300 is arranged between the mucking bucket body 100 and the first mucking plate 200; the first adjusting assembly 300 is adapted to adjust the angle between the first mucking plate 200 and the mucking bucket body 100. When encountering large-angle uphill and downhill tunnel routes, the first adjusting assembly 300 adjusts the angle between the first mucking plate 200 and the mucking bucket body 100, so that the mucking stones can always fall on the first mucking plate 200, thereby solving the problem that the mucking stones do not directly fall through the mucking bucket to damage the belt conveyor when encountering large-angle uphill, and the problem that the friction between the mucking stones and the mucking plate is too large when encountering large-angle downhill, which cannot normally muck.
[0042] Specifically, the shape of the mucking channel is a fan-shaped channel, and the entrance of the mucking channel is a fan-shaped opening; it should be noted that the shape of the mucking channel can be changed according to actual needs, such as a circular tube-shaped channel or other irregular channels.
[0043] Specifically, as shown in Figure 4 , the first mucking plate 200 is a trapezoidal plate; the shape of the first mucking plate 200 is as consistent as possible with the shape of the mucking channel, which can maximize the guarantee that all mucking soil passes through the first mucking plate 200; the first side of the first mucking plate 200 is hingedly connected with the mucking bucket body 100, thereby realizing the rotatable connection between the first mucking plate 200 and the mucking bucket body 100; further, the first mucking plate 200 is rotatably connected with the mucking bucket body 100 through a clamping plate, one side of the clamping plate is fixedly connected with the mucking bucket body 100 by welding or bonding; a rotating groove is formed in the clamping plate. The first side of the first mucking plate 200 is the side close to the mucking bucket body 100; the end of the first side of the first mucking plate 200 is provided with a cylindrical protrusion; the cylindrical protrusion is adapted to be rotatably connected with the rotating groove in the clamping plate, wherein the first mucking plate 200 and the clamping plate are first installed by sliding insertion, and then the assembled clamping plate is fixedly connected with the mucking bucket body 100.
[0044] It should be noted that the first spillage plate 200 in the prior art cannot change the included angle with the muck bucket body 100, and the falling path of the muck stone is always vertically downward. During normal travel of the tunneling machine, there is a certain included angle between the falling path of the muck stone and the first spillage plate 200. Assuming that the whole tunneling machine goes uphill to the left side, when the angle of inclination is large, the included angle between the falling path of the muck stone and the first spillage plate 200 will become small, so that part of the muck stone cannot pass through the first spillage plate 200, thereby causing damage to the conveyor belt. When the angle of inclination is large, the included angle between the falling path of the muck stone and the first spillage plate 200 will become large, the first spillage plate 200 will receive the muck stone, but the friction between the muck stone and the first spillage plate 200 increases, so that the muck stone cannot normally spill due to its own gravity, thereby affecting the spilling efficiency.
[0045] According to the above, since the included angle between the falling path of the muck stone and the first spillage plate 200 will become small when the angle of inclination is large, in the present application, as shown in Figure 2 , the included angle between the first spillage plate 200 and the muck bucket body 100 is increased by the first adjusting assembly 300, so as to ensure that the included angle between the falling path of the muck stone and the first spillage plate 200 is within the normal spilling range. Since the included angle between the falling path of the muck stone and the first spillage plate 200 will become large when the angle of inclination is large, in the present application, as shown in Figure 3 , the included angle between the first spillage plate 200 and the muck bucket body 100 is reduced by the first adjusting assembly 300, so as to ensure that the included angle between the falling path of the muck stone and the first spillage plate 200 is within the normal spilling range.
[0046] It should be noted that in order to further increase the spilling effect, a second spillage plate is also provided at the entrance of the spilling channel, and the second spillage plate has a certain included angle with the muck bucket body 100. The second spillage plate has a guiding effect on the muck stone, and the muck stone moves towards the first spillage plate 200 through the second spillage plate.
[0047] Further, the tunneling machine muck bucket structure provided by the embodiments of the present application includes a first adjusting assembly 300, which includes a first telescopic oil cylinder 310. The first end of the first telescopic oil cylinder 310 is adapted to be connected with the spilling channel in the muck bucket body 100, and the second end of the first telescopic oil cylinder 310 is adapted to be connected with the first spillage plate 200. Since one side of the first spillage plate 200 is rotationally connected with the muck bucket body 100, the first telescopic oil cylinder 310 can change the included angle between the first spillage plate 200 and the muck bucket body 100 during the telescopic process. In the present application, the telescopic amount of the first telescopic oil cylinder 310 is controlled, so as to realize precise control of the rotation angle of the first spillage plate 200. For example, if it is desired to increase the angle between the first spillage plate 200 and the muck bucket body 100, the telescopic amount of the first telescopic oil cylinder 310 is increased, and if it is desired to reduce the angle between the first spillage plate 200 and the muck bucket body 100, the telescopic amount of the first telescopic oil cylinder 310 is reduced.
[0048] It should be noted that, in order to realize the stable connection of the first telescopic oil cylinder 310 and the muck bucket body 100 and the first muck plate 200, a first base is arranged at a position corresponding to the first end of the first telescopic oil cylinder 310 on the muck bucket body 100, the first base is fixedly connected with the muck bucket body 100 by welding, and the first end of the first telescopic oil cylinder 310 is rotatably connected with the first base; a second base is arranged at a position corresponding to the second end of the first telescopic oil cylinder 310 on the first muck plate 200, the second base is fixedly connected with the first muck plate 200 by welding, and the second end of the first telescopic oil cylinder 310 is rotatably connected with the second base.
[0049] It should be noted that, in order to further improve the automation level, the first telescopic oil cylinder 310 can be connected with the control unit, and the extension amount of the first telescopic oil cylinder 310 can be controlled in real time through the control unit, so that the adjustment of the first muck plate 200 is more convenient and simple.
[0050] Further, the muck bucket structure of the tunneling machine provided in the embodiment of the application further comprises a connecting ring 700 and a sliding cover plate assembly 500, wherein the connecting ring 700 is arranged on one side of the muck bucket body 100; the connecting ring 700 is fixedly connected with the muck bucket body 100; wherein the first side of the sliding cover plate assembly 500 is adapted to be slidably connected with the connecting ring 700, and the second side of the sliding cover plate assembly 500 is adapted to be slidably connected with the muck bucket body 100; part of the sliding cover plate assembly 500 is adapted to cover part of the entrance of the muck sliding channel. In the embodiment, the sliding cover plate assembly 500 and the muck bucket body 100 form an inlet for muck therebetween, and the size of the inlet for muck can be adjusted by the sliding connection between the sliding cover plate assembly 500 and the connecting ring 700.
[0051] In specific implementation, whether the size of the inlet for muck needs to be adjusted is determined by the operator observing the size of the falling muck stones, for example, if the muck stones are large, in order to avoid the muck stones being stuck in the inlet for muck, the sliding cover plate assembly 500 needs to be moved away from the first muck plate 200, and if the muck stones are small, in order to avoid the muck stones not passing through the first muck plate 200, the size of the inlet for muck needs to be reduced, and the sliding cover plate assembly 500 needs to be moved towards the first muck plate 200.
[0052] Further, as shown in Figure 2 and Figure 3As shown, the mucking machine muck bucket structure provided by the embodiments of the present application further comprises at least one connecting pipe 400; a first end of the connecting pipe 400 is adapted to be fixedly connected with the muck bucket body 100, and a second end of the connecting pipe 400 is adapted to be fixedly connected with the connecting ring 700. In the embodiment, two connecting pipes 400 are provided, and the two connecting pipes 400 are respectively arranged on the two sides of the connecting ring 700; the connecting pipe 400 is arranged between the muck bucket body 100 and the connecting ring 700, so as to ensure the stability of the sliding assembly during the sliding process, and make the overall structure more stable.
[0053] It can be understood that the number of the connecting pipes 400 can be reasonably increased according to actual needs. For example, if the size of the muck bucket body 100 is large, the number of the connecting pipes 400 can be three or four, and the more the number of the connecting pipes 400, the better the stability of the overall structure. Specifically, the two ends of the connecting pipe 400 are provided with flanges, the connecting pipe 400 is fixedly connected with the flanges by welding, and the flanges are fixedly connected with the muck bucket body 100 and the connecting ring 700 by bolt connection respectively.
[0054] Further, the second adjusting assembly 600 is arranged between the muck bucket body 100 and the cover plate assembly; the second adjusting assembly 600 is adapted to adjust the distance between the sliding cover plate assembly 500 and the muck bucket body 100. In the embodiment, the movement of the sliding cover plate assembly 500 is driven by the second adjusting assembly 600, so as to facilitate the adjustment of the distance between the sliding cover plate assembly 500 and the muck bucket body 100, increase the automation degree of the overall equipment, and increase the work efficiency; it should be noted that if the second adjusting assembly 600 is not arranged, the sliding cover plate assembly 500 needs to be manually pushed by manpower, which has safety hazards and consumes time and energy.
[0055] Specifically, the muck bucket body 100 comprises a first muck bucket 110 and a second muck bucket 120; the first muck bucket 110 is arranged on one side of the second muck bucket 120; and the first muck bucket 110 and the second muck bucket 120 are detachably connected. The muck bucket body 100 is combined by the first muck bucket 110 and the second muck bucket 120, and the split type design of the muck bucket body 100 can realize rapid disassembly, so as to facilitate the replacement and maintenance in the later period. In the embodiment, the first muck bucket 110 and the second muck bucket 120 are detachably connected by bolt connection, and as an alternative embodiment, the first muck bucket 110 and the second muck bucket 120 can also be detachably connected by buckles or other ways.
[0056] It can be understood that the boundary line between the first bucket 110 and the second bucket 120 is the symmetry line of the bucket body 100, and the first bucket 110 and the second bucket 120 are symmetrically arranged, which has the advantage of facilitating processing. In specific cases, the boundary line between the first bucket 110 and the second bucket 120 can be shifted left or right, and the shifted boundary line can be disassembled more conveniently in specific cases.
[0057] Specifically, as shown in Figure 4 and Figure 5 The sliding cover plate assembly 500 includes a first front cover plate 510, a second front cover plate 520, a first rear cover plate 530, and a second rear cover plate 540; the first front cover plate 510 is adapted to be slidably connected with the first bucket 110; the first rear cover plate 530 is fixedly connected with the first front cover plate 510, and the first rear cover plate 530 is adapted to be slidably connected with the connecting ring 700; the second front cover plate 520 is adapted to be slidably connected with the second bucket 120; the second rear cover plate 540 is adapted to be fixedly connected with the first front cover plate 510; and the second rear cover plate 540 is adapted to be slidably connected with the connecting ring 700.
[0058] It should be noted that the sliding cover plate assembly 500 is composed of the first front cover plate 510, the second front cover plate 520, the first rear cover plate 530, and the second rear cover plate 540, and the split sliding cover plate assembly can be quickly disassembled, facilitating replacement and later maintenance; the first rear cover plate 530 is fixedly connected with the first front cover plate 510 by means of bolts, so as to ensure that the first front cover plate 510 and the first rear cover plate 530 can move synchronously; specifically, the first front cover plate 510 is slidably connected with the first bucket 110 by means of a sliding groove, and the first rear cover plate 530 is slidably connected with the connecting ring 700 by means of a sliding groove; the second front cover plate 520 and the second rear cover plate 540 are fixedly connected by means of bolts, so as to ensure that the second front cover plate 520 and the second rear cover plate 540 can move synchronously; specifically, the second front cover plate 520 is slidably connected with the second bucket 120 by means of a sliding groove, and the second rear cover plate 540 is slidably connected with the connecting ring 700 by means of a sliding groove; the sliding groove does not need to be driven by electricity during use, has very low operating cost, has a long service life, and has significant economic benefits.
[0059] Further, the tunneling machine muck bucket structure provided by the embodiment of the present application further comprises a second adjusting assembly 600, the second adjusting assembly 600 comprises a second telescopic oil cylinder and a third telescopic oil cylinder; the second telescopic oil cylinder is adapted to be arranged between the first front cover plate 510 and the first muck bucket 110; and the third telescopic oil cylinder is adapted to be arranged between the second front cover plate 520 and the second muck bucket 120. It should be noted that the second telescopic oil cylinder and the third telescopic oil cylinder control the movement of the first front cover plate 510 and the movement of the second front cover plate 520 respectively, and the first front cover plate 510 is allowed to approach or move away from the first muck bucket 110 and the second front cover plate 520 is allowed to approach or move away from the second muck bucket 120 respectively, so that the muck inlet is divided into a first muck inlet surrounded by the first front cover plate 510 and the first muck bucket 110 and a second muck inlet surrounded by the second front cover plate 520 and the second muck bucket 120, and the size of the first muck inlet and the second muck inlet can be controlled independently, for example, when the size of the muck stone is just suitable for the first muck inlet, only the size of the first muck inlet needs to be adjusted, when the size of the muck stone is just suitable for the second muck inlet, only the size of the second muck inlet needs to be adjusted, and when the size of the muck stone is suitable for both the first muck inlet and the second muck inlet, the sizes of the first muck inlet and the second muck inlet are adjusted simultaneously; the size of the first muck inlet and the second muck inlet controlled respectively can adapt to more scenes and increase the practicability.
[0060] As an alternative embodiment, the first adjusting assembly 300 and the second adjusting assembly 600 are not limited to the telescopic oil cylinder, but can also be a gas cylinder or an electric telescopic cylinder.
