Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rotary drill perforation depth detection, and more specifically, to a rotary drill perforation depth detection device. Background Art
[0002] When a rotary drill drills a hole, it relies on a pressurizing and rotating mechanism to provide a sufficiently large axial pressure and rotation torque to the drill bit through the drill rod. The rotary drill bit drills and rotates on the rock at the same time, generating static pressure and impact dynamic pressure on the rock. The rotary drill drill needs to measure the depth of the hole during the drilling process to prevent internal collapse caused by over-drilling during the drilling process. However, in the existing depth detection devices, the detected depth is relatively vague, making it difficult to accurately judge the drilling distance, resulting in large errors. Utility Model Content
[0003] In order to overcome the deficiencies of the prior art, the utility model provides a perforation depth detection device for a rotary drill, which has the advantage of improved accuracy in detecting depth.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a perforation depth detection device for a rotary drill, comprising a fixed column, a connecting bracket fixedly installed on the side of the fixed column, a connecting column fixedly installed inside the fixed column, a slide groove one is opened inside the connecting column, a slider one is slidably connected inside the slide groove one, a connecting plate is fixedly installed on the side of the slider one away from the connecting column, a motor is fixedly installed above the connecting plate, a rotating shaft is fixedly installed on the output end of the motor, and a pressure plate is fixedly installed on the left side of the connecting plate.
[0005] As a preferred technical solution of the utility model, there are four fixed columns, and the four fixed columns are aligned and distributed in parallel in pairs in the front, back, left and right directions. A slide groove 2 is opened inside the fixed column close to the pressure plate, and a slider 2 is slidably connected inside the slide groove 2. A connecting block is fixedly installed on the left side of the slider 2, and a telescopic rod is fixedly installed above the connecting block. A spring is sleeved on the outer side of the telescopic rod, and a button is fixedly installed above the spring. An alarm is fixedly installed below the connecting block, and a connecting rod is fixedly installed in front of the spring. A bolt is meshed inside the connecting rod, and a limiting sleeve is fixedly installed on the inner side of the connecting bracket.
[0006] As a preferred technical solution of the utility model, there are multiple connecting brackets, and the multiple connecting brackets are respectively distributed on the left and right sides of the connecting plate, and the multiple connecting brackets are divided into two cross shapes.
[0007] As a preferred technical solution of the utility model, there are two connecting columns, which are distributed on the front and rear sides of the motor, and there are two slide grooves, which are both located inside the connecting columns.
[0008] As a preferred technical solution of the utility model, the pressing plate is located directly above the button, the pressing plate is in a rectangular shape, and the pressing plate is located inside the four fixing columns.
[0009] As a preferred technical solution of the utility model, the bolt is located in front of the fixing column with the second slide groove, and contacts the front of the fixing column after being engaged with the connecting rod.
[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0011] 1. The utility model has a spring connected by sliding inside the second slide slot, a button fixedly installed above the spring and an alarm fixedly installed below the connecting block. First, the connecting block is set to a distance equal to the distance between the connecting plates and the depth of the hole to be drilled. When the connecting plate is drilling, it will move downward with the pressing plate. When the specified distance is reached, the pressing plate will press the button downward to trigger the alarm. When the alarm is heard, the drilling rig is turned off to drill. At this time, the drilling depth will be consistent with the estimated depth, thereby achieving the effect of perforation depth detection.
[0012] 2. The utility model fixes a limit sleeve on the inner side of the connecting bracket. The limit sleeve is located inside the four fixed columns, and the interior of the limit sleeve is hollow. It surrounds the outside of the rotating shaft. When the rotating shaft is driven by the motor to rotate at high speed, the drill bit at the bottom is driven to drill holes. Since the center of gravity of the rotating shaft is downward, slight shaking may occur during drilling, causing the drilling position to shift. At this time, the limit sleeve will limit the rotating shaft to ensure that the drilling direction of the drill bit is fixed. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.
[0020] like Figures 1 to 5 As shown, the utility model provides a perforation depth detection device for a rotary drill, comprising a fixed column 1, a connecting bracket 2 is fixedly installed on the side of the fixed column 1, a connecting column 3 is fixedly installed inside the fixed column 1, a slide groove 4 is opened inside the connecting column 3, a slider 5 is slidably connected inside the slide groove 4, a connecting plate 6 is fixedly installed on the side of the slider 5 away from the connecting column 3, a motor 7 is fixedly installed above the connecting plate 6, a rotating shaft 8 is fixedly installed on the output end of the motor 7, and a pressure plate 9 is fixedly installed on the left side of the connecting plate 6.
[0021] A cone drill is fixedly mounted on the bottom of the rotating shaft 8, and the cone drill is driven by the motor 7 to rotate rapidly, so that the cone drill has the effect of breaking the soil and drilling a hole.
[0022] Among them, there are four fixed columns 1, and the four fixed columns 1 are all aligned and distributed in parallel in pairs in the front, back, left and right directions. A slide groove 2 10 is opened inside the fixed column 1 close to the pressure plate 9, and a slider 2 11 is slidably connected inside the slide groove 20. A connecting block 12 is fixedly installed on the left side of the slider 2, and a telescopic rod 13 is fixedly installed above the connecting block 12. A spring 14 is sleeved on the outer side of the telescopic rod 13, and a button 15 is fixedly installed above the spring 14. An alarm 16 is fixedly installed below the connecting block 12, and a connecting rod 17 is fixedly installed in front of the spring 14. A bolt 18 is meshed inside the connecting rod 17, and a limiting sleeve 19 is fixedly installed on the inner side of the connecting bracket 2.
[0023] The alarm 16 is located on the right side of the connecting column 3. When the cone drill reaches a certain depth, the alarm 16 will sound an alarm so that the machine can be stopped in time to achieve the alarm effect.
[0024] There are multiple connecting brackets 2 , and the multiple connecting brackets 2 are respectively distributed on the left and right sides of the connecting plate 6 , and the multiple connecting brackets 2 are divided into two cross shapes.
[0025] A plurality of connecting brackets 2 are distributed and fixedly connected to the two front and rear fixing columns 1, so as to connect and support the overall frame of the device.
[0026] There are two connecting columns 3 , which are located at the front and rear sides of the motor 7 ; there are two slide grooves 4 , which are both located inside the connecting columns 3 .
[0027] The two connecting columns 3 support the entire connecting plate 6. When the connecting plate 6 is controlled to be raised or lowered by other devices, the two connecting columns 3 provide guidance and support.
[0028] The pressing plate 9 is located directly above the button 15 . The pressing plate 9 is in a rectangular shape and is located inside the four fixing columns 1 .
[0029] The pressing plate 9 will be driven by the connecting plate 6 to move downward. After the button 15 is set to the specified distance, when the drilling rig drills to the specified depth, the pressing plate 9 will press on the top of the button 15 while following the alarm 16 to move downward, so that the button 15 triggers the alarm 16, causing the alarm 16 to sound an alarm in time and stopping the drilling rig from continuing the drilling work.
[0030] The bolt 18 is located in front of the fixing column 1 with the second slide groove 10 , and contacts the front of the fixing column 1 after being engaged with the connecting rod 17 .
[0031] After the bolt 18 is engaged with the connecting rod 17, the connecting block 12 will be fixed to the left side of the chute 10 through the connecting rod 17, so that after the specific distance is measured, it is fixed to achieve the effect of timely alarm.
[0032] The working principle and use process of this utility model:
[0033] First, install the drill bit to the bottom of the rotating shaft 8, and at the same time control the overall height of the rotating shaft 8 so that the bottom of the drill bit just touches the ground;
[0034] Then, the connection block 12 is set to a distance equal to the distance between the connection plate 6 and the depth of the hole to be drilled. When the connection plate 6 is drilling, it will move the pressing plate 9 downward. When the specified distance is reached, the pressing plate 9 will press the button 15 downward to trigger the alarm 16 to sound an alarm. When the alarm is heard, the drilling machine is turned off to drill. At this time, the drilling depth will be consistent with the estimated depth, thereby achieving the effect of perforation depth detection;
[0035] At this time, since the limiting sleeve 19 is fixedly installed on the inner side of the connecting bracket 2, and the limiting sleeve 19 is located inside the four fixing columns 1, and the inside of the limiting sleeve 19 is hollow, surrounding the outer side of the rotating shaft 8, when the rotating shaft 8 is driven by the motor 7 to rotate at a high speed, the drill bit at the bottom is driven to drill holes. Since the center of gravity of the rotating shaft 8 is downward, there may be a slight shake during drilling, resulting in the deviation of the drilling position. At this time, the limiting sleeve 19 will limit the rotating shaft 8 to ensure that the drilling direction of the drill bit is fixed;
[0036] Finally, after drilling, the depth of the hole is reviewed to ensure the accuracy of the hole and ensure safety during the work process.
