[0021] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0022] Reference Figures 1 to 3 The first aspect of this application discloses a tunneling propulsion beam, including a main beam 100, a protective member 200, a sensor 300, and a sensing member 400. A tunneling trolley 110 is slidably mounted on the main beam 100, and the tunneling trolley 110 is equipped with a chisel for crushing and tunneling operations. The protective member 200 is mounted on the main beam 100 and disposed below the tunneling trolley 110. The protective member 200 defines a receiving groove 210, the opening of which faces a first side in the width direction of the main beam 100. The sensor 300 is mounted in the receiving groove 210, and the sensing member 400 is mounted on the tunneling trolley 110 and disposed on the first side in the width direction of the main beam 100. The sensing member 400 cooperates with the sensor 300 to detect the position of the tunneling trolley 110.

[0023] In this embodiment of the tunneling propulsion beam, by installing a protective member 200 on the main beam 100 and then installing the sensor 300 in the receiving groove 210 of the protective member 200, the probability of the sensor 300 coming into contact with falling rocks, debris, etc. can be effectively reduced, thereby reducing the risk of damage to the sensor 300. The opening of the receiving groove 210 faces one side of the main beam 100, further reducing the risk of falling rocks, debris, etc. entering the receiving groove 210. The sensing element 400 is arranged in cooperation with the sensor 300 on the first side in the width direction of the main beam 100, which can also reduce the risk of being hit by falling rocks, debris, etc., thereby ensuring the stable operation of the sensor 300 and improving tunneling efficiency.

[0024] In some embodiments of this application, reference is made to Figure 3As shown, the sensor 300 includes a sensing rod 310, which is installed in the receiving groove 210. When the sensing rod 310 is installed in the receiving groove 210, it can be completely retracted into the receiving groove 210 and will not protrude from the protective member 200. This ensures that during the operation of the tunneling trolley 110, most of the falling rocks, debris, etc. can only come into contact with the protective member 200 and cannot damage the protective member 200.

[0025] In some specific embodiments of this application, the width of the receiving groove 210 can be set to gradually increase along its depth direction. For example, the width of the receiving groove 210 is the smallest at the opening side, which can further reduce the probability of falling rocks, debris, etc. entering the receiving groove 210.

[0026] In some embodiments of this application, the axial length of the receiving groove 210 is usually specifically set according to the length of the sensing rod 310, and is not limited in this embodiment.

[0027] In some embodiments of this application, the protective component 200 is detachably connected to the main beam 100. Specifically, both ends of the protective component 200 along its length are connected to the main beam 100 by fasteners, which can be bolts or similar structures. Connecting the protective component 200 and the main beam 100 with fasteners facilitates the individual replacement of the protective component 200 or its disassembly for maintenance, thereby reducing maintenance costs and improving maintenance efficiency.

[0028] In some embodiments of this application, the sensing rod 310 is detachably mounted to the protective member 200, for example, the sensing rod 310 is fixed to the protective member 200 by fasteners such as bolts; see reference Figure 2 , Figure 3 As shown, the end of the sensing rod 310 can be fixed inside the protective component 200 by setting a baffle 220. The baffle 220 can be connected to the protective component 200 by bolts or other structures. The sensing rod 310 and the protective component 200 are detachably connected, which facilitates the individual replacement or disassembly of the sensing rod 310 for maintenance, thereby reducing maintenance costs and improving maintenance efficiency.

[0029] In some embodiments of this application, reference is made to Figure 1 , Figure 2As shown, the sensing element 400 includes a magnetic ring, which is installed on the open side of the protective element 200. The tunneling trolley 110 slides along the main beam 100, causing the magnetic ring to move relative to the sensing rod 310. Specifically, the tunneling trolley 110 has a downwardly extending mounting block 111, on which the magnetic ring is installed. Preferably, the magnetic ring is detachably connected to the mounting block 111 by fasteners such as bolts, which facilitates individual replacement of the magnetic ring and reduces maintenance costs. When the tunneling trolley 110 slides along the main beam 100, it causes the magnetic ring to slide synchronously, thereby changing the relative position of the magnetic ring and the sensing rod 310. The sensing rod 310 positions the tunneling trolley 110 by sensing the position of the magnetic ring.

[0030] It should be noted that the sensing element 400 does not directly contact the sensor 300. Specifically, there is a certain gap between the magnetic ring and the sensing rod 310, which can reduce the wear caused by the relative movement between the two and avoid damage to the sensor 300 when the sensing element 400 is damaged or deformed.

[0031] In some embodiments of this application, the protective component 200 is preferably made of metal. For example, different metal materials may be used depending on the actual situation, such as aluminum alloy. The specific material used is not limited in this embodiment.

[0032] The tunneling rig according to the second aspect of this application includes the aforementioned tunneling propulsion beam. Since the tunneling rig includes the aforementioned tunneling propulsion beam, it possesses at least all the beneficial effects of a tunneling propulsion beam, which will not be elaborated upon here.
