Abstract
Description
Technical Field
[0001] This utility model belongs to the field of underground support and standardized construction of underground panels, and specifically relates to an underground support anchor hook device. Background Technology
[0002] In downhole shotcrete and anchor mesh support operations, industry standards impose certain requirements on the thickness of the shotcrete. Meeting these requirements is crucial to ensuring the quality of the support structure. Current technologies measure shotcrete thickness using methods such as drilling probes and measuring cross-sections, which are complex, time-consuming, and labor-intensive. Secondly, red zone warning within the downhole panel is typically achieved using red zone ropes. However, these ropes lack fixed suspension points on both sides. Generally, the ropes are hung on the metal mesh after the support structure is damaged. This method is not only improperly implemented but also poses safety hazards. Utility Model Content
[0003] This utility model provides a downhole support anchor hook device, which aims to solve the problems of cumbersome measurement of shotcrete thickness and non-standard setting of red zone in the downhole panel in the above-mentioned background art.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows:
[0005] A downhole support anchor hook device is characterized in that it includes an anchor rod and a measuring structure. The anchor rod includes an anchor rod body, a threaded washer, and a nut. One end of the anchor rod body is threaded. The threaded washer and the nut are both located at the threaded end of the anchor rod body. The measuring structure includes a measuring cap. One end of the measuring cap is connected to a hook, and the other end of the measuring cap is threadedly connected to the anchor rod body.
[0006] Furthermore, the measuring cap is welded with clips, there are two clips, and a pin is provided between them. The hook is rotatably fixed between the clips by the pin.
[0007] Furthermore, the measuring cap is marked with graduations.
[0008] The beneficial effects of this utility model are: it allows for direct observation of whether the thickness of the sprayed grout meets the requirements based on the original support, and can also be used as a red zone warning rope and other item hanging point. Attached Figure Description

[0012] In the diagram, 1 is the anchor bolt, 2 is the measuring structure, 3 is the anchor bolt body, 4 is the threaded washer, 5 is the nut, 6 is the measuring cap, 7 is the clamp, 8 is the pin, and 9 is the hook. Detailed Implementation
[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0014] like Figure 1-3 As shown, a downhole support anchor hook device includes an anchor 1 and a measuring structure 2. The anchor 1 includes an anchor body 3, a threaded washer 4, and a nut 5. One end of the anchor body 3 is threaded. The threaded washer 4 and the nut 5 are both located at the threaded end of the anchor body 3. The anchor body 3 is based on the anchor 1, with the tail thread extended. The threaded washer 4 plays a role in dispersing pressure during anchor support. The nut 5 fixes the anchor 1 and provides space for the installation of the measuring structure 2. The measuring structure 2 includes a measuring cap 6, one end of which is connected to a hook 9, and the other end of the measuring cap 6 is threadedly connected to the anchor body 3.
[0015] Furthermore, the measuring cap 6 is marked with centimeter-level graduations for intuitive reading. It has two clips 7 welded to its top, with a pin 8 between them. The hook 9 is rotatably fixed between the clips 7 via the pin 8. The pin 8 allows for quick assembly and disassembly of the hook 9 to adapt to different scenarios. The hook 9 provides a standard hanging point for the red rope in the red zone and can also be used to hang other items.
[0016] Before measuring the thickness of the shotcrete, insert the anchor body 3 into the anchor hole of the anchor 1, inject cement mortar for anchoring, and install the threaded washer 4 and nut 5 in sequence. At this time, the thread length needs to be reserved to ensure the installation space of the measuring cap 6. Screw the measuring cap 6 to the tail of the anchor body 3, determine the scale direction, and ensure the "0" scale reference. Rotate the hook 9 so that its opening faces the direction to be suspended. The pin 8 passes through the clamps 7 on both sides to fix the hook 9.
[0017] During spraying, the measuring structure is wrapped with a plastic bag to prevent clogging by the sprayed material. After spraying, the plastic bag is removed, and the exposed scale of the measuring cap 6 (i.e., the sprayed thickness) is read directly, solving the problem of cumbersome sprayed thickness measurement. After verifying that the sprayed thickness meets the standard, a red rope is hung on hook 9 to avoid damaging the support netting while standardizing the setting of the red zone warning.
