Technical Field

[0001] This utility model relates to the field of shaft excavation technology, specifically a guide and positioning device for shaft excavation using a full-face tunneling machine. Background Technology

[0002] The sunken shaft tunneling equipment is designed for building deep shafts with specific supports in underground areas with high groundwater levels. This equipment can be used to excavate soil, transport excavated materials and complete shaft support while continuously tunneling the shaft. The shaft tunneling machine consists of components such as a telescopic milling arm, machine frame and support shoe unit.

[0003] Before a tunnel boring machine can excavate a shaft, a pit of a certain depth must be dug in the ground. During the excavation of the pit, it is necessary to ensure the verticality of the support installed or poured into the pit. Therefore, it is necessary to ensure the verticality of the pit. However, since the pit is excavated manually, it is inconvenient to repeatedly inspect and adjust the pit during the excavation process. After the pit is excavated, it is also not convenient to quickly position and assemble the hoisting equipment for the shaft support around the pit. Utility Model Content

[0004] The purpose of this utility model is to provide a guiding and positioning device for shaft excavation of a full-face tunneling machine, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A guiding and positioning device for shaft excavation using a full-face tunneling machine, comprising:

[0007] The positioning assembly includes multiple base plates, one of which has multiple No. 1 threaded sleeves fixedly installed at equal angles on one side surface, and the other base plates have top frames fixedly installed on one side surface.

[0008] Multiple connecting components are arranged at equal angles between multiple base plates;

[0009] Multiple guide components are fixedly installed on one side surface of the top frame. Each guide component includes a No. 1 U-shaped seat fixedly installed on one side surface of the top frame. A No. 1 arc-shaped slide rail is movably engaged inside the No. 1 U-shaped seat. A No. 1 slider is slidably connected inside the No. 1 arc-shaped slide rail. A pendant is movably provided on one side of the No. 1 slider.

[0010] The auxiliary components are located on one side of the No. 1 U-shaped seat.

[0011] Furthermore, a pointed cone is fixedly installed on the other side surface of one of the base plates, and a second helical rod is screwed onto one side surface of the remaining base plates. Multiple first helical rods are screwed onto one side surface of multiple base plates at equal angles, and a pad is fixedly installed at the lower end of the first helical rod.

[0012] Furthermore, one end of the first arc-shaped slide rail is provided with a slot, and the other end of the first arc-shaped slide rail is fixedly installed with a block, which is movably inserted into the adjacent slot.

[0013] Furthermore, the connection component includes:

[0014] An extension rod is movably positioned between the two base plates;

[0015] The thread is fixed at both ends of the outer surface of the extension rod.

[0016] Preferably, the extension rod is screwed into a first threaded sleeve via a thread, and a second threaded sleeve is screwed into the other end of the extension rod. The second threaded sleeve is screwed into a screw at a corresponding position. Infrared sensors are fixedly installed on the outer sides of both the first threaded sleeve and the screw at the corresponding position.

[0017] Furthermore, the auxiliary components include:

[0018] U-shaped seat number two is located on one side of U-shaped seat number one;

[0019] The second arc-shaped slide rail is connected to the second U-shaped seat by a movable locking mechanism.

[0020] Preferably, a stud is fixedly installed on one side surface of the second U-shaped seat, and the stud is screwed into the third threaded sleeve. The second arc-shaped slide rail has the same structure as the first arc-shaped slide rail, and a second slider is slidably connected inside the second arc-shaped slide rail.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. Fix the middle base plate with a pointed cone, then install the connecting components, and then install the remaining base plates. Insert the No. 1 arc-shaped slide rail into the No. 1 U-shaped seat, so that multiple No. 1 arc-shaped slide rails form a closed circle. This limits the area of ​​the shaft excavation. At the same time, by extending the fixed distance of the extension rod, and using multiple base plates on the outside as references, it is easy to quickly position and assemble the hoisting equipment for shaft support around the pit. The sledgehammer is then lowered into the pit and moves along the No. 1 arc-shaped slide rail, allowing workers to visually observe the verticality of the pit, which is convenient for excavating the pit.

[0023] 2. By installing extension rods of different lengths, the distance between the base plates can be adjusted to facilitate the excavation of shafts of different diameters. Infrared sensors make the installation position of multiple base plates more accurate. After the base plates are installed, the extension rods and the middle base plate can be disassembled to facilitate excavation.

[0024] 3. Fix the No. 2 U-shaped seat with studs, and install multiple No. 2 arc-shaped slide rails to form a circle, so that the pendant is installed on one side of the No. 2 slider, which is vertically parallel to the inner wall of the shaft support in the pit, so as to facilitate observation and adjustment of the verticality of the shaft support during installation or pouring.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-5In this embodiment of the utility model, a guide and positioning device for shaft excavation of a full-face tunnel boring machine includes a positioning component 1. The positioning component 1 includes multiple base plates 101. Multiple No. 1 threaded sleeves 105 are fixedly installed at equal angles on one side surface of one base plate 101. Top frames 108 are fixedly installed on one side surface of the remaining base plates 101. Multiple connecting components 2 are arranged at equal angles between the multiple base plates 101. Multiple guide components 3 are fixedly installed on one side surface of the top frame 108. The guide component 3 includes a No. 1 U-shaped seat 301 fixedly installed on one side surface of the top frame 108. A No. 1 arc-shaped slide rail 302 is movably engaged inside the No. 1 U-shaped seat 301. A No. 1 slider 303 is slidably connected inside the No. 1 arc-shaped slide rail 302. A pendant 306 is movably provided on one side of the No. 1 slider 303. An auxiliary component 4 is movably provided on one side of the No. 1 U-shaped seat 301.

[0033] Specifically, a base plate 101 is installed at the center of the shaft excavation, multiple connecting components 2 are installed at equal angles, and the remaining base plates 101 are installed at the outermost end of the connecting components 2, so that the remaining base plates 101 form a circle around the middle base plate 101. Then, a circle of appropriate size is drawn out by the guide component 3 to limit the excavation range.

[0034] Example 1

[0035] like Figure 2-4 As shown, in this embodiment, a pointed cone 102 is fixedly installed on the other side surface of one base plate 101, and a second spiral rod 109 is screwed onto one side surface of the remaining base plates 101. Multiple first spiral rods 103 are screwed onto one side surface of multiple base plates 101 at equal angles. A pad 104 is fixedly installed at the lower end of the first spiral rod 103. A slot 304 is opened at one end of the first arc-shaped slide rail 302, and a locking block 305 is fixedly installed at the other end of the first arc-shaped slide rail 302. The locking block 305 is movably inserted into the adjacent slot 304.

[0036] In this embodiment, the middle base plate 101 is fixed by the cone 102, and multiple first-order spiral rods 103 are turned to make them abut the ground at different heights to ensure the level of the base plate 101. After the connecting component 2 is installed, the remaining base plates 101 are installed, and the second spiral rod 109 is turned to insert it into the ground to fix the remaining base plates 101. The first arc-shaped slide rail 302 is locked inside the first U-shaped seat 301. Through the movable insertion of the locking block 305 and the locking groove 304, multiple first-order arc-shaped slide rails 302 form a closed circle, thereby limiting the area of ​​the shaft excavation. At the same time, by extending the fixed distance of the extension rod 201, the multiple outer base plates 101 are used as references to facilitate the quick positioning and assembly of the shaft support hoisting equipment around the pit. The pendant 306 is lowered into the pit and moves along the first arc-shaped slide rail 302, allowing the workers to intuitively observe the verticality of the pit and facilitate the excavation of the pit.

[0037] like Figure 1-3 As shown, in this embodiment, the connecting component 2 includes: an extension rod 201 movably disposed between two base plates 101, and a thread 202 fixedly disposed at both ends of the outer surface of the extension rod 201; the extension rod 201 is screwed into a first threaded sleeve 105 via the thread 202, and a second threaded sleeve 203 is screwed into the other end of the extension rod 201; the second threaded sleeve 203 is screwed into a screw 107 at a corresponding position; and infrared sensors 106 are fixedly installed on the outer sides of both the first threaded sleeve 105 and the screw 107 at the corresponding position.

[0038] In practice, by installing extension rods 201 of different lengths, the distance between the base plates 101 can be adjusted to facilitate the excavation of vertical shafts of different diameters. The infrared sensor 106 includes a transmitting module and a receiving module. The transmitting module is fixed to the outside of the first threaded sleeve 105, and the receiving module is fixed to the outside of the screw 107. Thus, the infrared sensor 106 makes the installation position of multiple base plates 101 more accurate. After the base plates 101 are installed, the extension rods 201 and the middle base plate 101 are disassembled to facilitate excavation.

[0039] Example 2

[0040] Based on Example 1, in order to compensate for the problem that the verticality of the shaft support in the pit is not easy to observe when it is newly installed or poured.

[0041] like Figure 1 and Figure 4 As shown, in this embodiment, the auxiliary component 4 includes: a second U-shaped seat 401 movably disposed on one side of the first U-shaped seat 301, and a second arc-shaped slide rail 402 movably engaged with the second U-shaped seat 401; a stud is fixedly installed on one side surface of the second U-shaped seat 401, and the stud is screwed into the third threaded sleeve 307; the second arc-shaped slide rail 402 has the same structure as the first arc-shaped slide rail 302, and a second slider 403 is slidably connected inside the second arc-shaped slide rail 402.

[0042] In practice, the second U-shaped seat 401 is fixed with studs, and multiple second arc-shaped slide rails 402 are installed. The installation principle is the same as that of the first arc-shaped slide rail 302. Multiple second arc-shaped slide rails 402 form a circle, so that the pendant 306 is installed on one side of the second slider 403, which is vertically parallel to the inner wall of the shaft support in the pit, making it easy to observe and adjust the verticality of the shaft support during installation or pouring.
