DETAILED DESCRIPTION

[0031] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0033] Refer to the following Figures 1 to 13 The following describes tunneling equipment provided according to some embodiments of the present invention.

[0034] Combine Figure 1 、 Figure 2 、 Figure 5 and Figure 6As shown, in an embodiment of the present invention, a tunneling device is provided, comprising: a main body 100, a shovel blade 200, a pin 300, a traveling unit 400, a stopper 500, and a fastener 600. The main body 100 is provided with a first hinge portion 110 having a first hinge hole. The shovel blade 200 is provided with a second hinge portion 210 having a second hinge hole. The pin 300 passes through the first and second hinge holes, allowing the shovel blade 200 to rotate relative to the main body 100 about the pin 300. The pin 300 has an axial through hole 330. The traveling unit 400 is connected to the main body 100 and is used to drive the main body 100 to move. The stopper 500 is connected to the main body 100 and is located on the side of the first hinge portion 110 facing the running portion 400. The stopper 500 is used to limit the movement of the pin 300 toward the running portion 400. At least a portion of the fastener 600 passes through the axial through hole 330 and is connected to the stopper 500. The fastener 600 is detachably connected to the stopper 500 and is used to limit the movement of the pin 300 away from the running portion 400.

[0035] In the excavation equipment provided in this embodiment, the main body 100 and the shovel plate 200 are rotatably connected through a pin shaft 300. Specifically, the first hinge part 110 on the main body 100 is provided with a first hinge hole, and the second hinge part 210 of the shovel plate 200 is provided with a second hinge hole. The pin shaft 300 can pass through the first hinge hole and the second hinge hole.

[0036] Walking parts 400 are installed on both sides of the main body 100. The walking parts 400 can drive the main body 100 to move. For example, the walking parts 400 can be wheels, or the walking parts 400 can be tracks.

[0037] To ensure a stable connection between the shovel blade 200 and the main body, the pin 300 needs to be limited so that it is retained within the first and second hinge holes. The first side of the first hinge portion 110 faces the running portion 400, and the second side of the first hinge portion 110 faces away from the running portion 400. The limiting member 500 is located on the first side of the first hinge portion 110, so that a portion of the limiting member 500 contacts one end of the pin 300. Since the limiting member 500 is fixed to the main body 100 using screws or the like, the limiting member 500 can prevent the pin 300 from disengaging from the first and second hinge holes in the direction toward the running portion 400.

[0038] At least a portion of the fastener 600 passes through the axial through hole 330 and is then connected to the limit member 500. At this time, the fastener 600 is not easy to disengage from the axial through hole 330. The fastener 600 can limit the movement of the pin shaft 300 in the direction away from the walking part 400, and is used to limit the pin shaft 300 from disengaging from the first hinge hole and the second hinge hole in the direction away from the walking part 400.

[0039] When the pin 300 needs to be removed, the fastener 600 can be first removed from the stopper 500, and then the fastener 600 can be removed from the side of the first hinge 110 facing away from the walking unit 400. Since the removal process is performed from the side of the first hinge 110 facing away from the walking unit 400, the removal of the pin 300 will not be interfered with by the walking unit 400, and therefore, there is no need to remove the walking unit 400. This facilitates the removal of the pin 300 and, in turn, improves the maintenance convenience of the tunneling equipment.

[0040] In a possible application, the main body 100 includes a main body portion 120 and a first hinge portion 110 , and the main body portion 120 and the first hinge portion 110 are an integrally formed structure.

[0041] Combine Figure 2 and Figure 6 As shown, in the above embodiment, the fastener 600 includes: a bolt, the bolt includes a screw rod 610 and a nut 620 connected to each other, the screw rod 610 passes through the axial through hole 330 and is connected to the limit member 500, and along the radial direction of the pin shaft 300, the radial dimension of the nut 620 is greater than the radial dimension of the axial through hole 330.

[0042] In this embodiment, the screw 610 is connected to the stopper 500, thereby securing the screw 610. The radial dimension of the nut 620 is larger than the radial dimension of the axial through hole 330, so the nut 620 cannot extend into the axial through hole 330. The nut 620 can limit the movement of the pin 300 away from the walking portion 400.

[0043] In a possible application, a countersunk hole is provided on the pin shaft 300 , the nut 620 is located in the countersunk hole, and the countersunk hole is connected to the axial through hole 330 .

[0044] Combine Figure 3 、 Figure 4 and Figure 5 As shown, in any of the above embodiments, the limiting member 500 includes: a flange, and the axis of the flange coincides with the axis of the pin 300.

[0045] In this embodiment, the flange contacts one axial end of the pin 300, thereby achieving one-way positioning of the pin 300. The axis of the flange coincides with the axis of the pin 300, thereby improving the stability of the flange's positioning of the pin 300. The flange can be fastened to the main body 100 using screws or other fasteners.

[0046] Of course, in other embodiments, the flange and the pin 300 may not be concentrically arranged, or the flange may be designed to be an irregular shape according to usage requirements.

[0047] Combining Figure 3 and Figure 4 As shown in any of the above embodiments, the pin shaft 300 is provided with a pin extractor mounting hole 340 at each axial end thereof.

[0048] In this embodiment, the pin extractor mounting hole 340 is formed at each axial end of the pin shaft 300. When the pin shaft 300 needs to be disassembled, the fastener 600 or the limiting member 500 can be disassembled first, and then the pin extractor is connected to the pin extractor mounting hole 340, so that the pin can be pulled out by the pin extractor.

[0049] The pin extractor mounting hole 340 is provided at each end of the pin shaft 300, so that the pin shaft 300 can be conveniently disassembled from either end of the pin shaft 300.

[0050] The pin extractor mounting hole 340 in this embodiment is a threaded hole.

[0051] One or more pin extractor mounting holes 340 can be provided at the end of the pin shaft 300.

[0052] Combining Figure 2 , Figure 9 , Figure 10 and Figure 11 As shown in any of the above embodiments, the tunneling device further comprises a liquid inlet pipe 710, a mounting seat 720 and a liquid supply cup. The pin shaft 300 is provided with a liquid inlet 310 and a liquid guide channel 320, the liquid inlet 310 and the liquid guide channel 320 are in communication, the gap between the pin shaft 300 and the blade 200 is in communication with the liquid guide channel 320, the first end of the liquid inlet pipe 710 is connected to the liquid inlet 310, the mounting seat 720 is connected to the main body 100, the second end of the liquid inlet pipe 710 is connected to the mounting seat 720, the liquid supply cup is in communication with the mounting seat 720, the liquid supply cup is in communication with the liquid inlet pipe 710 through the mounting seat 720, and the liquid supply cup is used to supply lubricating liquid.

The mounting seat 720 is provided with an internal channel, the liquid supply cup is in communication with the liquid inlet pipe 710 through the internal channel, and the lubricating liquid flows into the liquid guide channel 320 through the liquid inlet 310.

[0054] The liquid supply cup can be removed from the mounting base 720 to facilitate refilling. Lubricating liquid can flow into the liquid channel 320 through the liquid inlet 310 on the pin 300. The gap between the shovel plate 200 and the pin 300 is connected to the liquid channel 320, allowing lubricating liquid in the liquid channel to flow between the shovel plate 200 and the pin 300. The shovel plate 200 and the pin 300 can rotate relative to each other, and the lubricating liquid can lubricate the space between the shovel plate 200 and the pin 300, thereby reducing friction between the shovel plate 200 and the pin 300 and slowing wear of the shovel plate 200 and the pin 300.

[0055] Combine Figure 7 and Figure 8 As shown, in any of the above embodiments, the liquid inlet 310 is communicated with the pin puller mounting hole 340 and is concentrically arranged with the pin puller mounting hole 340 .

[0056] In this embodiment, the liquid inlet 310 is concentric with the pin puller mounting hole 340, eliminating the need for multiple drillings in the pin shaft 300 and reducing the difficulty of machining the pin shaft 300.
