[0002] Drilling tools refer to tools used for drilling holes and other related purposes, mainly including exploration (well drilling) drilling tools and metallurgical furnace drilling tools. Since the second-floor drilling tools are higher than the ground, they need to be placed in a fixed position during drilling operations. High-altitude drilling tools are greatly affected by external factors and may cause dangerous accidents if not handled with caution. Therefore, an anti-reversal device suitable for drilling tools is designed to prevent the drilling tools from falling out easily after entering a specific area, thereby avoiding danger to construction workers.

[0003] A Chinese patent with authorization announcement number 202123157526.5 discloses an anti-reversal device for a screw drill, comprising a fixed plate, four fan-shaped grooves are equidistantly arranged at the upper end of the fixed plate, a connecting ring is rotatably connected to the inner side of the fixed plate, and a fixing rod is arranged on the inner side of the fan-shaped groove at the upper end of the connecting ring, and a limiting tube is rotatably connected to the middle part of the fixed plate, an inclined plate is rotatably connected to the inner end of the limiting tube, and the other side of the inclined plate is connected to the limiting tube through a first spring, and a clamping block is fixedly connected to the outer end of the limiting tube.

[0004] However, the anti-reversal device for the screw drill cannot prevent the drill from being tipped out by external force when the drill enters the designated area, and cannot realize the function of allowing the drill to enter but not exit. Therefore, technicians in this field need to further study and set up the anti-reversal device. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figures 1 to 3 , Figure 1 It is a three-dimensional structural schematic diagram of the utility model; Figure 2 for Figure 1 A side view structural schematic diagram of; Figure 3 for Figure 1 Schematic diagram of the top view structure.

[0027] The utility model provides a technical solution: an anti-reversal device suitable for drilling tools, comprising a base plate 2, wherein the base plate 2 may be provided with a plurality of through fixing holes 1 for fixing the base plate 2 by bolts, and may be fixed by welding if it is inconvenient to fix by bolts.

[0028] A base 17 is fixedly provided at the upper end of the bottom plate 2, which may be welded or otherwise connected, and the base 17 is connected to a rotating block 18 via a horizontally arranged second rotating shaft 16. The base 17 is provided for mounting the second rotating shaft 16, and the base 17 is connected to the rotating block 18 via the second rotating shaft 16, so that the device can achieve a certain angle of rotation in the vertical direction. When the device is in a horizontal state as a whole when anti-reversal is not required, the device can be adjusted to a vertical state.

[0029] An upper fixed plate 6 is fixed on the upper part of one side of the rotating block 18, and a lower fixed plate 13 is fixed on the lower part, and both of the fixing methods can be welding. A limit plate 8 that can rotate within a certain range is connected between the upper fixed plate 6 and the lower fixed plate 13 through the first rotating shaft 4 that runs through the two, and the rotation direction of the limit plate 8 is circumferential rotation around the first rotating shaft 4. An arc structure 10 is set at the end of one side of the limit plate 8, and a straight structure 9 is set on the other side. The setting of the arc structure 10 is to facilitate the smooth entry of the drilling tool. A spring 7 is connected to one side of the straight structure 9 on the limit plate 8, and the other end of the spring 7 is fixed by the first rotating shaft 4. A second limit pin 19 can be set through the bottom end of the first rotating shaft 4 for fixing.

[0030] The setting of the limit plate 8 is used to limit the drilling tool to prevent the drilling tool from reversing. The spring 7 arranged on the limit plate 8 makes the limit plate 8 automatically rebound to its position after the drilling tool passes through, thereby preventing the drilling tool from falling out from the side of the spring 7. The spring 7 is fixed by the first rotating shaft 4, and the other end of the spring 7 can be clamped with one side of the limit plate 8. At the same time, a limit column is arranged on the arc side to prevent it from falling out from the straight side.

[0031] In order to solve the problem of reducing the wear between the first rotating shaft 4 and the upper fixing plate 6, as shown in FIG. Figure 1 As shown, a first gasket 5 is provided at the junction between the upper surface of the upper fixing plate 6 and the end of the first rotating shaft 4 .

[0032] In order to solve the problem that the limit plate 8 does not move up and down during the rotation process, as Figure 2 As shown, a third gasket 21 is provided at the junction of the upper surface of the limiting plate 8 and the lower surface of the upper fixing plate 6, and a second gasket 20 is provided between the lower surface of the limiting plate 8 and the upper surface of the lower fixing plate 13, so that the limiting plate 8 will not move up and down during the rotation process.

[0033] As an improvement, a limiting column 11 is provided between the upper fixing plate 6 and the lower fixing plate 13 on the side relatively far from the spring 7 to solve the problem of limiting the position of the limiting plate 8 after rebounding to the original position. There can be two limiting columns 11, and the bottom ends of the limiting columns 11 can be fixed in position by having a first limiting pin 12 provided therethrough to prevent the limiting columns 11 from falling off during use of the device.

[0034] In addition, a buffer pad 23 may be provided on the outer side of the limiting column 11 to play a buffering role when the limiting plate 8 rebounds, and also to avoid contact between metals and reduce noise.

[0035] In order to further solve the problem that the limit plate 8 fails to limit after being bounced up by external force during use, two vertical support columns 14 can be fixed above the bottom plate 2, which can be fixed by bolts. A detachable rectangular pin 3 is horizontally provided between the two support columns 14. A third limit pin 22 is provided at one end of the rectangular pin 3, and the third limit pin 22 can be conveniently disassembled to achieve the purpose. When the device is used to prevent the drilling tool from turning over, the rectangular pin 3 can limit the horizontal position of the upper fixed plate 6. At the same time, when the device is not in use, after the limit plate 8 is turned up and folded around the second rotating shaft 16 with the rotating block 18, the rectangular pin 3 can lock the position of the lower fixed plate 13 to prevent the limit plate 8 from falling down, thereby ensuring that other working conditions of the drilling operation with the device installed are not affected.

[0036] Furthermore, in order to solve the problem that the limiting plate 8 is in a horizontal state during use, as Figure 1 As shown, a horizontal beam 15 is fixed between the bottoms of the support columns 14 to ensure that the limiting plate 8 is in a horizontal state as a whole during the use of the device.

[0037] The specific implementation methods disclosed in the present invention omit detailed descriptions of known functions and known components. To ensure the compatibility of the equipment, the operating methods adopted are consistent with the parameters of commercially available equipment.

[0038] The anti-reversal device for drilling tools has the following beneficial effects:

[0039] 1. Through the horizontally arranged second rotating shaft, the device can achieve a certain angle of rotation in the vertical direction. When the anti-reversal function is used, the device is in a horizontal state as a whole. When the anti-reversal function is not required, the device can be adjusted to a vertical state.

[0040] 2. By setting a limit plate, and setting the end of one side of the limit plate to an arc-shaped structure, it is convenient for the drilling tool to enter smoothly and be limited. In addition, a limit column can be set on the arc-shaped side to prevent the drilling tool from falling out from this side.

[0041] 3. By setting the spring, after the drill enters from the arc end, the limit plate will automatically rebound to prevent the drill from falling out from the spring side.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
