[0001] The utility model relates to the technical field of tunnel anchoring operation equipment, in particular to a tow chain hidden anchor drilling mechanism bracket and an anchor digger. Background Art

[0002] Tunnel anchoring operations can effectively improve the construction safety of tunnels. Anchor diggers are integrated digging and anchoring equipment that integrates digging, anchoring and transportation. They effectively improve construction efficiency and reduce the labor intensity of construction personnel. Therefore, they are widely used. However, because the anchor drilling mechanism drag chain and anchor arm part of the anchor digger are distributed side by side, the anchor drilling mechanism is relatively wide. The anchor drilling mechanism of the anchor digger is distributed on both sides of the tunnel boring machine, which makes the width of the whole machine wider and difficult to apply to construction operations in narrow tunnels.

[0019] The following is a further description of the specific implementation of the utility model in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0021] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention. Embodiment 1:

[0022] like Figure 1 As shown, this embodiment provides a drag chain hidden anchor drilling mechanism bracket, which is composed of a support plate 1, a pressure block 2, a bottom bracket 3 and a drag chain support frame 6. The pressure block 2 is fixedly connected to the support plate 1, and the lower end of the bottom bracket 3 is horizontally slidably connected between the pressure block 2 and the support plate 1. The drilling and anchoring slide 4 of the anchor drilling mechanism is slidably connected to the bottom bracket 3. The drag chain support frame 6 is fixedly connected to the support plate 1 and placed below the drilling and anchoring slide 4. The head and tail ends of the drag chain 5 of the anchor drilling mechanism are respectively fixedly connected to the drag chain support frame 6 and the drilling and anchoring slide 4. The drag chain hidden anchor drilling mechanism bracket places the drag chain and the drag chain support frame below the drilling and anchoring slide 4 of the anchor drilling mechanism, fully utilizing the lateral space of the anchor drilling mechanism, reducing the width of the anchor drilling mechanism, and further reducing the width of the whole machine, so that the anchor digging machine can be applied to the construction of narrow tunnels, thereby improving the application range of the anchor digging machine.

[0023] Specifically, the support plate 1 is used to carry the anchor drilling mechanism, and the pressure blocks 2 are fixed on the support plate 1 and are distributed on both sides of the bottom of the bottom bracket 3, and there are several of them. The bottom bracket 3 is placed on the support plate 1 and is restricted by the pressure blocks 2, and can only slide forward and backward. The drilling and anchoring slide 4 is placed on the bottom bracket 3 and is also restricted to slide forward and backward relative to the bottom bracket 3. The drag chain support frame 6 is fixed on the support plate 1, and the drag chain 5 is placed on the drag chain support frame 6. The drag chain 5 and the drag chain support frame 6 are placed under the drilling and anchoring slide 4 and hidden inside the drilling and anchoring slide 4. The head and tail of the drag chain 5 are respectively fixed on the drilling and anchoring slide 4 and the drag chain support frame 6. When the bottom bracket 3 and the drilling and anchoring slide 4 slide forward and backward, the drag chain 5 can slide forward and backward with the drilling and anchoring slide 4, and the movement space of the drag chain 5 is limited by the drag chain support frame 6 to prevent the drag chain 5 from shaking. A number of first support columns 7 are arranged at the front and rear ends of the drag chain support frame 6 to support and connect the drag chain support frame 6. The number and position of the first support columns 7 arranged at the front end of the drag chain support frame 6 are based on the premise that they do not block the forward sliding movement of the bottom bracket 3. In addition, the pressing block 2 located inside the anchor drilling mechanism to limit the bottom bracket 3 is hidden at the bottom of the drag chain support frame 6.

[0024] like Figure 2As shown, the bottom bracket 3 is a box-type welded structure, and a drag chain guide plate 3.1 and a first supporting rib 3.2 are welded on the inner side of the rear end of the bottom bracket 3. The drag chain guide plate 3.1 and the first supporting rib 3.2 are vertically fixedly connected to prevent the drag chain 5 from interfering with the bottom bracket 3 when the drag chain 5 slides back and forth independently following the drilling and anchoring slide 4.

[0025] like Figure 3 As shown, for ease of assembly, the drag chain support frame 6 is split into a lower drag chain support frame 6.1 and an upper drag chain support frame 6.2, which are fixed to each other by bolts. The upper drag chain support frame 6.2 can be a sheet metal bending part or a sheet metal welding structure; Figure 4 As shown, the lower drag chain support frame 6.1 is a split welded structure, and a number of second support ribs 6.1.2 and second support columns 6.1.1 are welded on the structure to ensure structural strength and cooperate with the first support column 7 that is less arranged at the front end of the drag chain support frame 6 relative to the rear end of the drag chain support frame 6 to prevent overturning when assembling the drag chain 5. The length of the second support column 6.1.1 is less than the first support column 7 and does not contact the bottom bracket 3 after the drag chain 5 is assembled. The second support column 6.1.1 and the second support rib 6.1.2 need to avoid the pressing block 2 hidden in the lower part of the drag chain support frame 6 during design and production, and the connecting plate 6.1.3 is used to fix the lower drag chain support frame 6.1 on the support plate 1. Alternatively, the drag chain support frame 6 can be processed into an integral welded structure. Embodiment 2:

[0026] This embodiment provides an anchor mining machine, comprising the drag chain hidden anchor drilling mechanism bracket described in the first embodiment, and the support plate 1 is fixedly connected to the anchor mining machine.

[0027] It should be noted that the contents not described in detail in the present invention are all prior art.

[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
