Description

Technical Field

[0001] The utility model relates to tunneling equipment for lined or unlined tunnels or adit, in particular to an advance drilling machine and a full-face tunneling machine. Background Art

[0002] In addition to traditional highway, rail and other transportation tunnels, full-face tunnel boring machines (shield machines, TBMs, etc.) are currently also widely used in tunnel construction in mining and other fields. Due to the deep burial depth of tunnels in the mining field, the underground geological conditions are complex. For example, there may be karst caves, toxic gas areas, faults and other geological conditions. If they are not handled in advance, on the one hand, it will affect the normal excavation of the equipment, and on the other hand, it will also affect the safety of the construction workers. Therefore, it is necessary to conduct preliminary exploration of the geological conditions in front of the excavation face and take different safety response measures for different geological conditions. In order to pre-explore the geological conditions in front of the excavation face, some current full-face tunnel boring machines are equipped with advance drilling rigs.

[0003] The structure and installation method of the existing advance drilling rig for full-section tunnel boring machines can be seen in the Chinese utility model patent with authorization announcement number CN211258618U and authorization announcement date August 14, 2020. The patent discloses an advance drilling rig positioning and adjustment device for a TBM rock tunnel boring machine, in which the disclosed advance drilling rig is directly installed on the main beam of the TBM. During operation, the positioning adjustment device can be used to achieve up and down pitch swings and left and right rotation swings, thereby drilling holes at different positions.

[0004] The above patent discloses a typical installation method and structure of the advance drilling rig, which is to install it directly in the middle of the main beam of the tunnel boring machine, and be able to perform pitch swing and left and right rotation. However, in actual engineering, the main beam of the tunnel boring machine is usually used as a pedestrian walkway and material storage point, and in some cases, the utilization rate of the advance drilling rig is not high. And because the advance drilling rig is often large in structure, when it is installed in the middle of the main beam of the tunnel boring machine, it will occupy the pedestrian walkway and material storage space, resulting in problems such as poor passage of personnel and inconvenient material storage. Utility Model Content

[0005] The purpose of the utility model is to provide an advance drilling rig, so that when not in use, the power head and its bracket and other parts of the advance drilling rig that occupy a large space can be moved to one side of the main beam of the tunnel boring machine, thereby freeing up the space at the corresponding position of the main beam of the tunnel boring machine, thereby solving the problem that the advance drilling rig occupies the pedestrian passage and material storage space of the main beam of the tunnel boring machine when not working.

[0006] At the same time, the purpose of the utility model is also to provide a full-face tunnel boring machine using the above-mentioned advance drilling rig to solve the problems of inconvenience in personnel passage and material storage existing in the full-face tunnel boring machine equipped with the advance drilling rig.

At the same time, since the transverse moving seat cooperates with the transverse track in the upper and lower and front and rear directions, it can also ensure that the advance drilling rig can withstand the overturning moment when working, ensuring its normal operation. In summary, the advance drilling rig of the utility model solves the problem that the existing advance drilling rig occupies the pedestrian passage and material storage space of the main beam of the tunnel boring machine when not working.

DETAILED DESCRIPTION

[0031] During the excavation of a full-face tunnel boring machine, such as a TBM, the top of the main beam of the tunnel boring machine is usually used as a pedestrian passage and material storage point due to the limited underground space and the large number of equipment. After the advance drilling machine 102 is arranged in the middle of the left and right directions of the main beam 101, the space on the left and right sides of the advance drilling machine 102 will be limited at the same time, and it is not enough to be used as a pedestrian passage and material storage point. In fact, the width of the power head 21 and the power head bracket of the advance drilling machine 102, which occupy the most space in the left and right directions, is smaller than the width of the main beam 101. Therefore, arranging the advance drilling machine close to the left or right side of the main beam 101 can make room for a pedestrian passage and material storage space on the other side. At the same time, in order to ensure that the advance drilling machine 102 still has a sufficient operating range in the left and right directions when in use, the advance drilling machine 102 can be installed on the main beam 101 with adjustable left and right positions.

[0032] The technical solution of the advance drilling machine 102 of the present utility model is proposed based on the above concept. Specifically, the present utility model is equipped with a base for the advance drilling machine 102. When in use, the advance drilling machine 102 can be installed on the main beam 101 as a whole through the base, rather than installing the advance drilling machine 102 directly on the main beam 101. In order to make the position of the advance drilling machine 102 on the main beam 101 adjustable to make room for pedestrian passages or material storage space, the base includes a transverse track 103 and a transverse moving seat 104 that cooperates with the transverse track 103. The "transverse" in the transverse track 103 refers to the direction of the length extension of the main beam 101, that is, the longitudinal direction. In other words, the transverse track 103 is installed on the main beam 101 along the left and right direction of the main beam 101 when in use. The transverse moving seat 104 can reciprocate along the transverse track 103, thereby moving left and right on the main beam 101, and then reach the corresponding working position and the position (left and / or right side of the main beam 101) that can make room for pedestrian passages and material storage space.

[0033] In order for the advanced drilling machine 102 to work properly, it is necessary to ensure that it can be stably supported during operation, and cannot tip over or move longitudinally. The transverse moving seat 104 and the transverse track 103 are limited in the up and down and front and back directions. From the above description of the purpose of the transverse track 103 and the transverse moving seat 104, it can be known that the track can be a track of any structure such as a single track, a double track, a wheel track, a slide track, etc., and the transverse moving seat 104 can also be a moving seat of any structure, for example, the transverse moving seat 104 can be a frame-type structure or a structure with a panel. All of the above are within the protection scope of the advanced drilling machine of the utility model.

[0034] In order to facilitate the adjustment of the position of the power head 21 and the power head bracket, a transverse driving device can be connected to the transverse moving seat 104. The function of the transverse driving device is to drive the transverse moving seat 104 to move back and forth. Therefore, as long as it is a driving device that can output reciprocating motion, it is feasible, such as a cylinder, a screw nut mechanism, a gear rack mechanism, etc., which are all within the protection scope of the present utility model.

[0035] The structure of the embodiment 1 of the advance drilling rig of the utility model is as follows Figure 1-2As shown, in this embodiment, the power head bracket includes a slewing mechanism 22, a connecting mechanism 23 and a pitch driving cylinder 24, wherein the power head 21 is installed on the slewing mechanism 22, and can swing left and right around the vertical rotation center under the action of the slewing mechanism 22, so as to have a wider construction range in the left and right directions. The slewing mechanism 22 is installed on the connecting mechanism 23, and the connecting mechanism 23 specifically adopts a swing seat that can be pitched and swung, and a hinge structure is set at its rear end, and the pitch driving cylinder 24 is connected to the front end. When in use, the connecting mechanism 23 can be installed on the corresponding carrier through the hinge structure, and the other end of the pitch driving cylinder 24 is also connected to the corresponding carrier. The connecting mechanism 23 is driven to pitch and swing around the hinge axis of the hinge structure through the extension and contraction of the pitch driving cylinder 24, so that the advanced drilling rig has a wider operating range in the up and down directions. The above-mentioned structure of the advance drilling rig 102 is prior art. Although its structure is described in detail in this embodiment, those skilled in the art should be able to know that in the present utility model, the structure of the above-mentioned part of the advance drilling rig can adopt any structure existing in the prior art, which should be within the protection scope of the present utility model.

[0036] Combination Figure 1 , 2 It can be seen that in this embodiment, the transverse track 103 adopts a double track, which includes a front guide rail and a rear guide rail arranged on the main beam one after the other when in use, wherein the adjacent sides of the front and rear guide rails, that is, the rear side of the front guide rail and the front side of the rear guide rail are respectively provided with a card slot, the function of the card slot is to limit the transverse moving seat 104 in the front and rear and up and down directions, and at the same time play a role in guiding the left and right movement of the transverse moving seat 104. Figure 1 , 2 In the illustrated embodiment, the front and rear guide rails are both in a split structure, including a horizontal bottom plate, a vertical upright plate, and a horizontal top plate. However, those skilled in the art should understand that in some embodiments, the front and rear guide rails can also be in an integrated structure, and slots can be opened thereon by machining or the like. In addition, although the transverse track in Example 1 adopts a double-track structure, in some other embodiments, the transverse track can also be in a single track, such as an I-beam track, which will not be described in detail here.

[0037] The length of the transverse track 103 determines the movement range of the transverse moving seat, that is, determines the transverse movement range of the power head 21. Therefore, in order to ensure that one side of the advance drilling rig 102 can leave enough space on the main beam 101, the length of the transverse track 103 should generally not be less than 1 / 2 of the width of the main beam 101. In this case, the transverse track 103 can be arranged on the left or right side of the main beam 101 to achieve the switching of the position of the power head 21 between the middle and the left or right side of the main beam 101. Of course, in order to ensure that the advance drilling rig 102 has a wider operating range in the width direction of the main beam 101, the length of the transverse track 103 can be appropriately lengthened, for example, greater than or equal to 2 / 3 of the width of the main beam 101. Figure 2 It can be seen that in Figure 1 , 2 In the embodiment shown, the length of the transverse rail 103 reaches 4 / 5 of the width of the main beam 101. When the length of the transverse rail 103 is longer, it is arranged in the middle of the main beam 101 in the left-right direction, for example Figure 2 This structure is shown in the illustrated embodiment.

[0038] exist Figure 1 , Figure 2 In the illustrated embodiment, the transverse moving seat 104 adopts a "J"-shaped structure, which includes a top crossbeam 41 and support plates 42 at the front and rear sides of the crossbeam, and a slider 43 that slides with the above-mentioned slot is installed at the bottom of the outer side surface of the support plate 42. The transverse moving seat 104 constitutes the installation base of the power head bracket, the hinge structure of the connecting mechanism 23 is connected to the rear support plate of the transverse moving seat 104, and the pitch drive cylinder 24 is connected to the front side plate of the transverse moving seat 104. A space is formed between the front and rear support plates at the position below the crossbeam 41, and the space can be used for the corresponding components to pass through laterally. It should be specially noted here that although in Figure 1 , 2 In the embodiment shown, the transverse moving seat 104 cooperates with the transverse guide rail 103 through a slider. However, in some embodiments, the transverse moving seat 104 can also cooperate with the transverse guide rail 103 through structures such as rollers, which should also be within the protection scope of the present utility model.

[0039] like Figure 2 As shown, in the embodiment 1 of the advanced drilling machine 102, a lateral movement drive device is connected to the lateral movement seat 104, and the lateral movement drive device here adopts a lateral movement drive cylinder 105, and the lateral movement drive device has a connecting seat 106 for connecting with the main beam 101, and the connecting seat 106 includes a hinge seat 61 and a cylinder body connecting member hingedly mounted on the hinge seat, and the cylinder body connecting member is fixedly connected to the cylinder body of the lateral drive cylinder, and specifically adopts a clamp 62 here. Figure 2It can be seen that the transverse driving device is arranged horizontally, one end of which is connected to the connecting seat 106, and the other end passes through the space below the transverse moving seat 104 and is connected to the connecting arm 44 extending downward from the transverse moving seat 104. The connection here is specifically hinged. Figure 2 In the illustrated embodiment, a transverse driving device is provided, but in some cases, the transverse driving device may be omitted, in which case the transverse moving seat may be moved manually with the aid of auxiliary tools on site.
