Description

Technical Field

[0001] The utility model relates to the field of tunnel excavation, in particular to a slag cleaning device and a tunneling machine. Background Art

[0002] When the tunnel boring machine is excavating, a tunnel will be formed underground. The rocks or soil on the side walls or top walls of the tunnel will fall and accumulate at the bottom of the tunnel to form slag. During the advancement of the tunnel boring machine, these slag must be cleaned up in time to avoid affecting the normal advancement of the subsequent supporting equipment. Currently, there are two main cleaning methods: manual and mechanical automatic slag cleaning. Manual slag cleaning has low efficiency, high labor costs, and is prone to safety hazards. Therefore, more and more tunnel boring machines use mechanical automatic slag cleaning solutions.

[0003] For example, a Chinese invention patent application with an application publication date of October 1, 2021 and an application publication number of CN 113464158 A discloses a slag cleaning device for a full-face hard rock tunnel boring machine, which is arranged below the main beam and moves synchronously with the main beam. The slag cleaning device includes a semicircular slag cleaning frame, which includes an arc-shaped portion (i.e., an arc-shaped frame) and a straight portion. A special-shaped roller chain (i.e., a chain) is provided on the slag cleaning frame, and a slag cleaning bucket (i.e., a slag bucket) is fixedly provided on the chain. In order to realize the movement of the slag bucket, a driving wheel and a driven wheel are also provided. The movement of the chain is controlled by the driving wheel and the driven wheel, so that the chain connects to the slag bucket and reciprocates on the slag cleaning frame. In addition, in order to realize the tensioning of the chain, the driving wheel guide is provided on the slag cleaning frame and can move outward under the action of the tensioning cylinder. In order to clean the slag at different heights, the slag cleaning frame is also connected with a slag cleaning lower petal through a screw rod. The position of the slag cleaning lower petal is adjusted by adjusting the length of the screw rod, so as to clean the slag at different heights.

[0004] However, in the above technical solution, the slag cleaning frame is generally semicircular, which blocks the space under the main beam and is not conducive to the passage of construction personnel or materials. In order to clean up the slag at different heights, the position of the lower slag cleaning flap is adjusted by adjusting the screw. Since the chain has a certain length, during the movement of the lower slag cleaning flap, the positions of the driving wheel and the driven wheel need to be adjusted at the same time, so that the lengths of the driving wheel, multiple driven wheels and the chain supported by the lower slag cleaning flap are consistent, which makes the operation troublesome and the efficiency low.

DETAILED DESCRIPTION

[0034] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0035] The tunnel boring machine in the utility model is provided with a slewing mechanism between the slag cleaning frame and the main beam, thereby controlling the slag cleaning frame to rotate relative to the main beam, thereby facilitating the avoidance of personnel or materials at the bottom of the tunnel and facilitating passage.

[0036] In the embodiment of the tunnel boring machine of the present utility model:

[0037] like Figure 1 and Figure 4As shown, in this embodiment, the roadheader includes a main beam 76 and a slag cleaning device arranged below the main beam 76, wherein the slag cleaning device includes a slag cleaning frame, a chain 71 arranged on the slag cleaning frame, and a slag bucket 73 arranged on the chain 71. The slag cleaning frame includes a linear frame 3 and an arc frame 4, wherein the linear frame 3 is located on the top of the arc frame 4, thereby making the slag cleaning frame fan-shaped as a whole, and a chain 71 is further arranged on the periphery of the slag cleaning frame, and the chain 71 is looped around the periphery of the slag cleaning frame. A slag bucket 73 is fixedly arranged on the chain 71. Naturally, the slag bucket 73 can rotate with the chain 71. During the rotation, the slag bucket 73 collects the slag below the tunnel and rises along the outer circumference of the arc frame 4 until it enters the top of the linear frame 3 to complete the transfer and collection of the slag. During the rotation of the chain 71, an arc segment located on the outer circumference of the arc frame 4 and a straight segment connecting the two ends of the arc segment are formed, wherein the straight segment is located above the linear frame 3, and the linear frame 3 supports the straight segment. When the slag bucket 73 is in the straight segment, it is convenient to dump the slag, and the slag can enter the belt conveyor 75 for convenient transportation. At the same time, in order to prevent the slag from accumulating on the linear frame 3, a scraper plate 74 is also fixedly arranged on the chain 71. Of course, in other embodiments, the linear frame 3 may no longer be provided, and only the arc frame 4 may be provided. At this time, the chain 71 will also form straight segments at both ends of the arc segment due to the tension of the sprocket.

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, the slag cleaning frame is an integrated structure, and the slag cleaning frame also includes a connecting frame 5 fixedly connecting the linear frame 3 and the arc frame 4, wherein the connecting frame 5 is a frame structure connected by welding of multiple connecting rods. The connecting frame 5 is connected to the inner wall surface of the arc frame 4 by welding, and the connecting frame 5 is also provided with a fixing member for being arranged below the linear frame 3 and fixedly connected to the linear frame 3, and the fixing member is specifically a fixing frame 51, so that the connecting frame 5, the arc frame 4 and the linear frame 3 are fixedly connected together. Of course, in other embodiments, the linear frame 3 and the arc frame 4 can also be directly fixedly connected together without providing the connecting frame 5.

[0039] like Figure 5As shown, in order to better drive the chain 71, a driving mechanism for driving the chain 71 is provided on the linear frame 3, and the driving mechanism is used to drive the chain 71 to move, and synchronously drive the movement of the slag bucket 73. Specifically, the driving mechanism includes a driving motor and a driving sprocket provided on the driving motor, and the driving sprocket cooperates with the chain 71 to drive the chain 71 to move, and the driving sprocket also constitutes the driving wheel 62 in the device. In addition, a driven wheel 72 is also provided on the linear frame 3, so as to facilitate the reversal of the chain 71 here. Of course, in other embodiments, the driving mechanism can also be set as a hydraulic motor or other rotary power source.

[0040] In order to achieve the tensioning of the chain 71, the guide driving mechanism is set on the linear frame 3. Specifically, a guide seat 31 is fixedly set on the linear frame 3. The guide seat 31 is a rectangular frame structure. Both sides of the rectangular frame structure are provided with inwardly concave grooves. The driving mechanism is fixedly set on the mounting plate 61. There are two mounting plates 61. The two mounting plates 61 are arranged at intervals and a fixed gap is maintained between the two mounting plates 61. The mounting plate 61 is slidably set in the groove of the guide seat 31. At the same time, the groove of the guide seat 31 also constitutes the slide groove 311 of the guide seat 31. The mounting plate 61 slides and is set in the guide seat 31, thereby driving the driving mechanism to be set on the linear frame 3. Of course, in other embodiments, the guide seat 31 may no longer be set, and the slide groove 311 may be set at the bottom of the linear frame 3, and a slider adapted to the slide groove 311 may be set on the driving mechanism. Alternatively, in other embodiments, the driving mechanism may be directly fixed on the linear frame 3.

[0041] In order to perform tensioning, a telescopic mechanism for controlling the guiding movement of the driving mechanism is also provided between the linear frame 3 and the driving mechanism. Specifically, the telescopic mechanism is a telescopic oil cylinder 6, the cylinder body of which is provided on the linear frame 3, and the telescopic rod of which is provided on the mounting plate 61. Driven by the telescopic oil cylinder 6, the driving mechanism can be guided and moved relative to the linear frame 3, and the telescopic oil cylinder 6 also plays a role in limiting the position of the driving mechanism, so that the driving mechanism can be kept in a fixed position. Of course, in other embodiments, the telescopic mechanism may not be provided, and the driving mechanism is fixedly connected to the linear frame 3.

[0042] like Figure 1 and Figure 4As shown, the arrangement of the slag cleaning frame and the chain 71 makes the slag cleaning frame block the space at the bottom of the tunnel when in use, affecting the passage of personnel and materials. Therefore, the slag cleaning device also includes a slewing mechanism 1, wherein the slewing mechanism 1 includes a mounting structure for mounting on the main beam 76 and a connecting structure for connecting with the slag cleaning frame, and the connecting structure can rotate relative to the mounting structure around a vertical axis. In order to perform the slewing control of the slewing mechanism 1, the slewing mechanism 1 also includes a power source for controlling the relative rotation of the mounting structure and the connecting structure. In this embodiment, the slewing mechanism 1 can be a slewing drive with a slewing bearing and a driving power source. The slewing drive is a prior art and is not described here. Through the arrangement of the slewing mechanism 1, the slag cleaning frame has a slag cleaning state in which the straight section of the chain 71 is arranged perpendicular to the extension direction of the tunnel for the slag bucket 73 to transport the slag, and a evasive state in which the straight section of the chain 71 is arranged along the extension direction of the tunnel for the passage of personnel or materials. A connecting plate 11 is provided at the bottom of the connecting structure, and the connecting plate 11 is better connected to the slag cleaning frame.

[0043] In the slag cleaning process, in order to better clean the tunnels of different diameters and to gradually clean the thicker slag accumulation parts, a lifting structure for controlling the lifting movement of the slag cleaning frame is also provided between the connection structure of the rotary device and the slag cleaning frame. The lifting structure is a lifting cylinder 2, and four lifting cylinders 2 are provided. Both ends of each lifting cylinder 2 are hingedly connected to the connection structure and the slag cleaning frame. The width of the fixed frame 51 is greater than the width of the linear frame 3. The four lifting cylinders 2 are arranged in two rows, and the two rows of lifting cylinders 2 are respectively provided at the two ends of the fixed part extending out of the linear frame 3, so that the weight can be well distributed while supporting. In addition, the fixed frame 51 and the connecting plate 11 are both rectangular, and the lifting structure is provided at the vertex position of the fixed frame 51 and the connecting plate 11. Of course, in order to facilitate the connection between the fixed frame 51 and the connecting plate 11 and the lifting cylinder 2, ear plates are provided on the fixed frame 51 and the connecting plate 11, and the ear plates are hingedly connected to the lifting cylinder 2.

[0044] Of course, in other embodiments, two lifting cylinders 2 or six lifting cylinders 2 may be provided, and the lifting cylinders 2 are arranged in two rows. Alternatively, in other embodiments, only one lifting cylinder 2 may be provided, and the lifting cylinder 2 is fixedly provided on the connecting structure and the slag cleaning frame. Alternatively, in other embodiments, the fixing member and the connecting plate 11 are both circular, and the plurality of lifting cylinders 2 are evenly distributed around the circumference. Alternatively, in other embodiments, the lifting structure may be provided as a lifting cylinder or an electric push rod.

[0045] When the lifting cylinder 2 is in an articulated connection, in order to avoid the formation of an unreliable parallelogram structure between the multiple lifting cylinders 2, the hinge axes of the slag cleaning rack of two adjacent lifting cylinders 2 intersect or are in different planes, and the hinge axes of the two adjacent lifting structures and the connecting structure intersect or are in different planes. In this way, the lifting cylinder 2 will not swing, avoiding shaking during the slag cleaning process. Of course, in other embodiments, only two of the four lifting cylinders 2 intersect or are in different planes with the hinge axes of the connecting structure, and only two of the lifting cylinders 2 intersect or are in different planes with the hinge axes of the slag cleaning rack. Alternatively, in other embodiments, there may be three lifting cylinders 2 arranged as described above.

[0047] The structure of the slag cleaning device in this embodiment is the same as that of the slag cleaning device in the above-mentioned embodiment of the tunnel boring machine, and will not be repeated here.

The patent protection scope of the present invention shall be based on the claims. All equivalent structural changes made using the description and drawings of the present invention shall be included in the protection scope of the present invention.
