Description

Technical Field

[0001] This application relates to the field of protective device technology, and more specifically, to a safety protective device for geological and mineral exploration drilling. Background Technology

[0002] Geological and mineral exploration drilling involves supplying a certain axial pressure and torsion to the drill string through a drilling rig, thereby enabling the drill bit to extract rock and continuously drill deeper to obtain geological data. When the drill string enters the ground, protective devices are needed to prevent flying debris from injuring people.

[0003] The existing technology publication CN218971146U provides a drilling protection structure for water control in coal mines. When protecting the drilling mechanism, the drill bit passes through a rectangular hole and is positioned between two protective shells. Through the cooperation of a handle, threaded rod, sprocket, and chain, the two threaded rods can rotate synchronously. The threaded rods can drive the drive seats to move, and the two corresponding drive seats move in opposite directions. The drive seats can drive the protective shells to move towards the drill bit, so that the drill bit is positioned in two semi-circular holes. The two protective shells can block the debris during the drilling process and prevent flying debris from injuring the workers. Through the cooperation of the driving bevel gear and the driven bevel gear, the rotation of the threaded rod can drive the drive screw to rotate. The drive screw can drive the insertion rod to move downward through the threaded hole, so that the insertion rod can penetrate deep into the ground, thereby increasing the stability of the base and protective shell.

[0004] Although the device has many beneficial effects, the following problems still exist: when workers are drilling and the drill rod of the external drilling rig is thick or thin, it is difficult for workers to change to different specifications of protective shell according to the specific situation of the drill rod, which can easily reduce the flexibility of the device during use. In view of this, we propose a safety protection device for geological and mineral exploration drilling. Utility Model Content

[0005] This application provides a safety protection device for geological and mineral exploration drilling, which solves the technical problem in the prior art where, when workers are drilling and the drill rod of the external drilling rig is thick or thin, it is difficult for workers to change to different specifications of protective shells according to the specific condition of the drill rod, thus easily reducing the flexibility of the device during use. The device achieves the technical effect of enabling workers to quickly change to different specifications of protective shells according to the thickness of the drill rod of the external drilling rig when drilling the road surface, thereby improving the flexibility of the device during use.

[0006] This application provides a safety protection device for geological and mineral exploration drilling, including: a base plate;

[0007] A through slot is formed at the center of the top of the base plate. A first support frame is fixedly connected to one side of the top of the base plate. A guide rod is fixedly connected to the inner side of the first support frame. Two sliding sleeves are slidably fitted on the outer side of the guide rod. A protective shell is connected to one side of the sliding sleeve through a connecting mechanism. A groove is formed on one side of the protective shell. A second support frame is fixedly connected to the other side of the top of the base plate. A motor is installed on one side of the inner wall of the second support frame. A bidirectional lead screw is fixedly connected to one end of the output shaft of the motor. Two threaded sleeves are threaded on the outer side of the bidirectional lead screw.

[0008] The connecting mechanism includes a fixing plate, which is fixedly connected to the bottom of the sliding sleeve and is also fixedly connected to the screw sleeve. A slot is provided on one side of the top of the fixing plate, and a plug for cooperating with the slot is fixedly connected to the other side of the protective shell. The plug is slidably connected in the slot.

[0009] By adopting the above technical solution and setting up a connecting mechanism, when workers drill holes in the road surface, they can easily change protective shells of different specifications according to the thickness of the drill rod of the external drilling machine, thereby improving the flexibility of the device during use.

[0010] Optionally, the slot has a T-shaped cross-section.

[0011] By adopting the above technical solution, and by limiting the shape of the slot and the plug, the plug can be prevented from detaching from the slot at will, and the protective shell can be moved by the cooperation of the slot and the plug when the fixing plate moves horizontally along the direction of the guide rod.

[0012] Optionally, the top of the fixing plate is provided with a sliding groove, a slider is slidably connected in the sliding groove, a pull plate is fixedly connected to the top of the slider, and a stop block for blocking the insertion block is fixedly connected to the bottom of the pull plate.

[0013] By adopting the above technical solution, and by setting up sliders, pull plates and stops, it is easy for workers to move the stops to the position of the insert and the slot, thereby blocking the insert and preventing it from falling out of the slot at will, thus ensuring the stability of the protective shell.

[0014] Optionally, a crossbar is fixedly connected inside the groove, and the slider is slidably sleeved on the outside of the crossbar.

[0015] By adopting the above technical solution and setting a crossbar, the slider can move horizontally and stably in the groove along the direction of the crossbar, while the slider is blocked by the crossbar to ensure that it will not fall out of the groove and to prevent it from moving vertically.

[0016] Optionally, a spring is fixedly connected to one side of the slider, one end of the spring is fixedly connected to one side of the inner wall of the groove, and the spring is sleeved on the outside of the crossbar.

[0017] By adopting the above technical solution and setting a spring, when the stop block moves away from the slot, the pull plate will drive the slider to squeeze the spring, thereby increasing the resistance to the movement of the stop block and thus preventing the stop block from moving arbitrarily.

[0018] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0019] 1. By setting up a connection mechanism, when workers are drilling holes in the road surface, they can easily change the protective shell of different specifications according to the thickness of the drill rod of the external drilling machine, thereby improving the flexibility of the device when it is used.

[0020] 2. By setting sliders, crossbars, pull plates, and stops, it is easy for workers to move the stops to the position of the insert and slot, thereby blocking the insert and preventing it from falling out of the slot, thus ensuring the stability of the protective shell.

[0021] 3. By setting a spring, when the stop block moves away from the slot, the pull plate will drive the slider to compress the spring, thereby increasing the resistance to the movement of the stop block and thus preventing the stop block from moving arbitrarily. Attached Figure Description

Detailed Implementation

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figure 1 and Figure 2 This application discloses a safety protection device for geological and mineral exploration drilling. The safety protection device for geological and mineral exploration drilling includes: a base plate 1;

[0029] A through slot is provided at the center of the top of the base plate 1. A first support frame 2 is fixedly connected to one side of the top of the base plate 1. A guide rod 4 is fixedly connected to the inner side of the first support frame 2. Two sliding sleeves 5 are slidably sleeved on the outer side of the guide rod 4. A protective shell 6 is connected to one side of the sliding sleeve 5 through a connecting mechanism 3. A groove 7 is provided on one side of the protective shell 6. A second support frame 8 is fixedly connected to the other side of the top of the base plate 1. A motor 9 is installed on one side of the inner wall of the second support frame 8. The model of the motor 9 is 130ZFMA1-0003CBNM. A bidirectional lead screw 10 is fixedly connected to one end of the output shaft of the motor 9. Two threaded sleeves 11 are threaded on the outer side of the bidirectional lead screw 10.

[0030] The connecting mechanism 3 includes a fixing plate 31, which is fixedly connected to the bottom of the sliding sleeve 5 and is also fixedly connected to the screw sleeve 11. A slot 32 is provided on one side of the top of the fixing plate 31, and a plug 33 for cooperating with the slot 32 is fixedly connected to the other side of the protective shell 6. The plug 33 is slidably connected in the slot 32, which makes it convenient for staff to replace the protective shell 6 of different specifications and improves the flexibility of the device during use.

[0031] Reference Figure 2 and Figure 3 The slot 32 has a T-shaped cross section, which helps to prevent the insert 33 from detaching from the groove at will, so that the fixed plate 31 can move the protective shell 6 when it moves, and the protective shell 6 can move vertically.

[0032] Reference Figure 1 and Figure 4 The top of the fixed plate 31 is provided with a sliding groove, and a slider 34 is slidably connected in the sliding groove. A pull plate 37 is fixedly connected to the top of the slider 34, and a stop block 38 is fixedly connected to the bottom of the pull plate 37 to block the insert 33, thereby preventing the insert 33 from detaching from the slot 32 at will.

[0033] Reference Figure 1 and Figure 4 A crossbar 35 is fixedly connected inside the groove, and a slider 34 is slidably sleeved on the outside of the crossbar 35, thereby preventing the slider 34 from detaching from the groove.

[0034] Reference Figure 1 and Figure 4A spring 36 is fixedly connected to one side of the slider 34. One end of the spring 36 is fixedly connected to one side of the inner wall of the groove, and the spring 36 is sleeved on the outside of the crossbar 35, so as to prevent the slider 34 from moving at will.

[0035] The implementation principle of a safety protection device for geological and mineral exploration drilling in this embodiment is as follows: When the drill rod of the external drilling rig used for road drilling is thick or thin, the operator can pull the pull plate 37 to move the stop block 38 and the slider 34, causing the stop block 38 and the slider 34 to move away from the slot 32. The movement of the slider 34 will compress the spring 36. When the stop block 38 moves to a position where it no longer obstructs the slot 32, the operator can pull the protective shell 6 to move the insert block 33 upward, causing the insert block 33 to disengage from the slot 32, thus facilitating the replacement of the protective shell 6. Then, the insert block 33 of the new protective shell 6 is... Insert the 3-slot into the slot 32 and release the pull plate 37, causing the compressed spring 36 to rebound, thereby driving the slider 34 and the pull plate 37 to move. The movement of the pull plate 37 can drive the stop block 38 to move, so that the stop block 38 moves above the insert block 33 to block the insert block 33. Finally, the operator can start the motor 9 to drive the two screw sleeves 11 to move towards each other. The movement of the screw sleeves 11 can drive the fixed plate 31 to move. The movement of the fixed plate 31 can drive the protective shell 6 to move through the slot 32 and the insert block 33 until the two protective shells 6 abut against each other. Then the operator can put the drill rod of the drill into the groove 7 to prevent the stone chips from flying and injuring people during drilling.

[0036] This application provides a safety protection device for geological and mineral exploration drilling. By setting a connecting mechanism 3, when workers are drilling holes in the road surface, they can quickly change the protective shell 6 of different specifications according to the thickness of the drill rod of the external drilling machine, thereby improving the flexibility of the device when it is used.
